Problems solved by technology

[0004] However, as the service time of the oil pipe increases, or the quality of the oil pipe is low, once the oil pipe breaks, the hydraulic oil in the oil cylinder will be lost, causing the piston rod in the oil cylinder to drop, which will cause the lifting platform to lose the power of the piston rod. Falling due to support; or the connection between the piston rod of the oil cylinder and the lifting platform is fatigued and loosened or broken, causing the lifting platform to suddenly fall
It will endanger the personal safety of the operators located under the lifting platform and cause safety accidents.

Embodiment 1

[0045] A guide rail type lifting platform fall prevention device, such as figure 1 As shown, it includes a fixed plate 1, a rotating connecting plate 2, and a support rod 3.

[0046] like figure 1 As shown, the fixed plate 1 is provided with a first hinge hole 1-1 and a first positioning hole 1-3, and the side of the fixed plate 1 close to the rotating connecting plate 2 is welded and fixed with a guide post 1-2.

[0047] like figure 1 As shown, one end of the rotating connecting plate 2 is provided with a second hinged hole 2-1 and a guide slide hole 2-2, and the guide slide hole 2-2 is an arc-shaped hole centered on the axis of the second hinged hole 2-1 , the axis of the second hinge hole 2-1 refers to the orthographic projection of the axis of the second hinge hole 2-1 on the radial section of the second hinge hole 2-1, the radial section of the second hinge hole 2-1 The shape is circular, and the orthographic projection of the axis of the second hinged hole 2-1 on its ...

Embodiment 2

[0068] This embodiment 2 is the same as embodiment 1, the difference is that, as Figure 7 and Figure 8 As shown, the anti-falling device of a guide rail type lifting platform in Embodiment 2 also includes a stop switch 10, the stop switch 10 is arranged under the fixing plate 1, and the stop switch 10 is installed and fixed on the mounting plate 10-1. On the guide rail 7, the stop switch 10 cooperates with the lower end of the rotating connecting plate 1. like Figure 10 As shown, the stop switch 10 is electrically connected to the oil pump, specifically, the stop switch 10 is electrically connected to the hydraulic motor for driving the oil pump. In this embodiment, there are four stop switches 10, and what the stop switch 10 adopts is an automatic switch of the TR236 model.

[0069] when using it:

[0070] Before the operator goes to the bottom of the lifting platform 8 to perform operations, at first, the lifting platform 8 is lowered so that the lifting platform 8 fa...

Abstract

The invention discloses a guide rail type lifting platform anti-falling device, and relates to the technical field of anti-falling of lifting equipment. The device comprises a fixed plate, a rotary connecting plate and a supporting rod. The fixed plate is connected with a guide rail of a guide rail type lifting platform. One end of the rotary connecting plate is hinged to the fixed plate. The end,away from the fixed plate, of the rotary connecting plate is hinged to the supporting plate. By means of the device, in the process that an operator operates in the plate under the lifting platform,even if the lifting platform falls down suddenly, the lifting platform can be supported by the supporting rod and is prevented from falling down, thus, the safety of the operator under the lifting platform is guaranteed, safety accidents are avoided, and operation safety is improved.

Description

technical field [0001] The invention relates to the technical field of anti-falling equipment for lifting equipment, in particular to an anti-falling device for a guide rail type lifting platform. Background technique [0002] The guide rail type lifting platform includes a lifting platform, a guide rail, and an oil cylinder. The upper end of the piston rod of the oil cylinder is connected with the lifting platform, and the lifting platform rises and falls along the guide rail. [0003] When it is necessary to perform maintenance and other operations on the guide rail lifting platform, it is necessary to shut down the oil pump used to transmit hydraulic oil to the cylinder through the oil pipe. After the oil pump is shut down, the hydraulic oil in the cylinder will not change, so that the piston rod in the cylinder The position of the lifting platform does not change any more, so that the lifting platform stops lifting. At this time, the operator goes to the bottom of the li...
