Problems solved by technology

[0004] Another example is the work platform for preventing continuous involuntary operation disclosed by the Chinese patent whose publication number is CN107257773A, comprising: a floor structure, which has a width dimension and a depth dimension; and a safety guardrail, which is connected with the floor structure, and the control panel area can be The safety rail cooperates with and includes a sensor support bar having a top rail extending along the width dimension and side rails extending substantially perpendicularly from the top rail, each side rail comprising : an upper portion extending inwardly from the top rail along the depth dimension to a bend, and a lower portion extending outwardly from the bend along the depth dimension to the safety rail, configured to be The platform switch, which trips when a predetermined force is applied, is attached to the sensor support rod through a switch rod, which is held by a shear element, and the whole structure is a fixed structure, which is relatively rigid, especially when there is a large extrusion force In some cases, although the alarm can be issued, the impact on people is still relatively large, and the position of the human body is relatively limited, and the effect of avoiding danger is not good enough.

Embodiment 1

[0028] Embodiment 1, an anti-extrusion device, including an operating platform protective frame 1 for being installed on the protective rail of an aerial work platform, the operating platform protective frame 1 can adopt an existing conventional protective frame, and the protection of the protective frame An operating platform a1 is provided in the area, and at least one detection rod 2 for the human body to lean on is movably connected to the protective frame 1 of the operation platform. One or two, or even more, can be selected. The initial state of these detection rods 2 can maintain Stationary, when an abnormal situation such as obstacle extrusion occurs, the operator can touch the detection rod 2 and push a certain distance to produce a position change. The detection rod 2 is equipped with a position change sensor for triggering an alarm system alarm. Device 3, position change sensing device 3 can send position change information to the alarm system to shut down the action...

Embodiment 2

[0045] Embodiment 2, on the basis of Embodiment 1, considering the aesthetics of the structure on the equipment, the integrity and the reliability of the force, etc., the anti-extrusion device preferably has two detection rods 2 opposite to each other and opposite to each other. Position change sensing devices 3 are arranged at the ends, and the detection rod 2 should also be extended in the left and right directions. For the drawings, refer to all the drawings in Embodiment 1.

[0046] The left and right detection rods 2 can be respectively installed on the left and right two protective frames 10 through the installation structure in embodiment 1. This design further strengthens the structure, and the safety will be improved, because pushing any detection rod 2 can complete the alarm.

[0047] The position change sensing device 3 can be embedded in the end of the detection rod 2, and there are various specific implementation schemes, for example:

[0048] The position change...

Embodiment 3

[0052] Embodiment 3, the difference between this embodiment and the previous two embodiments lies in the further design of the detection rod 2 body, at least a part of the surface of the detection rod 2 is an arc-shaped part that can be contacted by the operator. Then the detection rod 2 should adopt a long cylindrical and horizontally placed rod structure, which is better in use. For the drawings, refer to all the drawings in Embodiment 1.

[0053] In addition, the outer part of the detection rod 2 should preferably be wrapped with a buffer layer 20 . The buffer layer 20 can adopt flexible materials such as sponge, latex, rubber, plastic, etc., to better protect the human body, and the detection rod 2 body can adopt a metal rod or a hard plastic rod.

[0054] Detection rod 2 is controlled at about 30cm as far as possible, should not be too long, and the swing distance of detection rod 2 is controlled within 15cm as far as possible, and the angle range of swing is controlled w...

Abstract

The invention relates to the technical field of extrusion preventing systems and particularly provides an extrusion preventing device and an overhead operation platform. The extrusion preventing device comprises an operation platform protective rack is installed on a protective fence of the overhead operation platform; the operation platform protective rack is movably connected with at least one detecting rod for a human body to lean against; and the detecting rod is provided with a position change sensing device used for triggering an alarming system to give an alarm, so higher safety is realized.

Description

technical field [0001] The invention relates to the technical field of an anti-extrusion system, in particular to an anti-extrusion device and an aerial work platform. Background technique [0002] Aerial work platforms are used more and more frequently in today's society, and its safety has attracted more attention. In particular, when obstacles occur above or behind the platform, it is very likely that the operator will not find it. When continuing to lift, the staff may be squeezed by obstacles, and it is more likely that the machine will continue to lift because the operator cannot release the operating handle in time, which will eventually cause more serious accidents. Anti-extrusion safety device. [0003] For example, the Chinese patent with the publication number CN208249834U discloses an anti-extrusion system for a work platform and an aerial work platform. The anti-extrusion system for the work platform is arranged on the work platform. And two ends are connected...
