Description

A kind of protective structure for aerial work platform

technical field

The invention relates to the field of electric power maintenance work tools and security protection, in particular to a protection structure of an aerial work platform.

Background technique

With the increase in infrastructure construction, the demand for aerial work platforms continues to increase. Aerial work platform is a kind of large-scale construction machinery equipment used to transport staff and work equipment to a specified height for operation, and is widely used in electric power, street lights, municipal administration, gardens, communications, airports, shipbuilding, transportation, advertising, photography lights at high altitudes field of work. The national standard GB3608.93 "Classification of Work at Heights" stipulates: "VL works at heights where it is possible to fall above the datum level of the drop height of 2 meters, which is called work at heights." Therefore, in order to ensure the safety of workers working at heights Because of this, more and more aerial work equipment has appeared.

Due to the limited area of the high-altitude environment, it is inevitable to encounter various obstacles that hinder the operation during high-altitude work. The blind area of the operating room will cause the operating platform to come into contact with obstacles, resulting in the shaking of the operating platform. If it collides with obstacles such as poles or cables, it may endanger the personal safety of operators and cause serious safety accidents.

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a protective structure for aerial work platforms, which solves the problem of lack of safety protection measures for the work platform during aerial power maintenance and installation of equipment, which is easy to cause safety accidents.

The present invention is achieved through the following technical solutions:

A protective structure for an aerial work platform, comprising a work platform and a protective fence, a safety protective fence is arranged around the operating platform, at least one set of protective frames is arranged on the periphery of the protective fence, and the inner side of the protective frame is movable through a telescopic piece It is arranged on the protective fence, and each outer side of the protective frame is provided with an ultrasonic probe. The ultrasonic probe transmits the detection situation of obstacles around the working platform to the controller. When the platform distance is less than the set distance, the controller activates the alarm device and controls the control switch for closing the working platform to close. The invention provides a protective structure for an aerial work platform. By setting a radar system, the distance between the work platform and the obstacle can be predicted in advance, so that the operator can turn off the moving power of the work platform or automatically control the shutdown, so collisions can be avoided. When a dead angle is detected, it can be protected by a protective frame; at least one set of protective frames is provided on the periphery of the protective fence, and the inner side of the protective frame is movably set on the protective fence through a telescopic piece. When the protective fence encounters an obstacle, the protective frame Through the expansion and contraction of the telescopic piece and the movement of the telescopic piece along the longitudinal chute on the protective fence, the collision force can be effectively absorbed by the two shrinking structures, thereby effectively preventing the work platform from swinging. The box can be moved and retracted in the opposite direction along the two collision surfaces, which can adapt to various high-altitude action environments

Further, each inner side of the protective frame is movably arranged on the protective fence through at least two telescopic pieces, the telescopic pieces include an I-shaped connector and a telescopic spring, and one end of the I-shaped connector is installed on the protective fence. The other end of the I-shaped connecting piece is installed in the horizontal sliding slot of the protective frame to telescopically slide, and a telescopic spring is sleeved on the I-shaped connecting piece between the protective fence and the protective frame.

Further, each side of the protective fence is provided with an anti-swing device.

Further, the anti-swing device includes a V-shaped sleeve, and a plurality of anti-damping balls are placed in the V-shaped sleeve.

Further, each side of the protective fence is also provided with a vibration switch. Once the control switch controlled by the radar cannot act as the power source to turn off the work platform, when the work platform swings, the vibration switch will be triggered and turned on according to the amplitude of the work platform swing or shaking. When the vibration switch is turned on, the vibration switch will be turned off by control Control the switch, thereby preventing the work platform from continuing to move, causing a larger crash.

Further, the vibration switch is a ball switch.

Further, the ball switch is also connected to the controller for control.

Further, a protective pad is provided on the outer side of the protective frame.

Compared with the prior art, the present invention has the following advantages and beneficial effects:

1.
