Problems solved by technology

However, due to the considerable weight of the equipment itself, when the operator adjusts the height of the equipment, improper operation occurs; or when the adjustment of the operating height of the equipment is completed, but the locking device cannot be locked; even the locking device In case of failure, there will be situations that cause the equipment to fall
At the same time, if the machine itself fails to take good preventive measures, it may cause injury to personnel and equipment

Embodiment Construction

[0033] see figure 1 , which is a schematic diagram of a machine in a preferred embodiment of the present invention. The present invention is a machine platform with an emergency fall prevention device, which mainly includes a machine platform 1 and an emergency fall prevention device 2 .

[0034] The machine platform 1 includes a lifting platform 12 and a pulley mechanism 3 . In this example, the pulley mechanism 3 includes a cable 31 and a pulley 32 . Such as figure 1 As shown, the lifting platform 12 also includes a slider 121 . In this way, the sliding block 121 of the lifting platform 12 can securely clamp one end of the cable 31 , and the other end of the cable 31 loops around the pulley 32 and is connected to a counterweight assembly 33 . In this example, the counterweight assembly 33 is formed by stacking a plurality of counterweights, which can be adjusted according to actual conditions.

[0035] see figure 2 and see also figure 1 , figure 2 It is an exploded...

Abstract

The invention provides a machine station with an emergency anti-fall device, mainly comprising a machine station and an emergency anti-fall device; the machine station comprises a lifting platform, a pulley mechanism and a cable; one end of the cable is fixedly arranged on the lifting platform and the other end thereof surrounds the pulley so as to drive the emergency anti-fall device; the emergency anti-fall device mainly comprises a turbulence ratchet and a unidirectional tenon; the turbulence ratchet and the unidirectional tenon are arranged in the internal space of the anti-fall device where the fluid is filled. Therefore, if the lifting platform falls suddenly, the cable is driven so as to lead the pulley and the turbulence ratchet of the anti-fall device to rotate synchronously, thus driving the end of the unidirectional tenon to stop a diversion ratchet and leading the diversion ratchet and the pulley not to rotate, thereby leading the cable to pull the lifting platform and avoid the lifting platform from falling any more and having the emergency anti-fall efficacy.

Description

technical field [0001] The invention relates to a fall prevention device, in particular to a machine platform with an emergency fall prevention device, which is used to prevent a sudden fall of a lifting platform carrying important equipment. Background technique [0002] In the known working machines or equipment, in order to facilitate the operator to adjust the equipment on the machine to an appropriate operating height, therefore, a lifting platform is designed on the machine body, and the equipment is fixed on the lifting platform. [0003] Generally speaking, the lifting platform itself is designed with a locking device to fix the equipment on it at an appropriate operating height. However, due to the considerable weight of the equipment itself, when the operator adjusts the height of the equipment, improper operation occurs; or when the adjustment of the operating height of the equipment is completed, but the locking device cannot be locked; even the locking device I...
