Embodiment 1

[0039] Such as figure 1 with figure 2 As shown, an anti-falling device for a material hoist includes a bottom plate 10, the front end of the bottom plate 10 is provided with an adjustment block 20, and the upper end of the adjustment block 20 is provided with a spring sheet 30, wherein the lower end of the adjustment block 20 An adjustment mechanism is provided that can drive the adjustment block 20 to move up and down between a pair of guide plates 40 located at the front end of the adjustment block 20. The adjustment mechanism includes a driving mechanism 1 and a number of locking mechanisms 2. The driving mechanism 1 is arranged on the front end of the bottom plate 10, and the driving mechanism 1 is connected with the lower end of the adjusting block 20, and the locking mechanism 2 is arranged on the front end of the bottom plate 10, and The locking mechanism 2 can lock the drive mechanism 1 to determine the position of the adjustment block 20, so that not only can the posit...

Embodiment 2

[0049] Such as figure 2 As shown, the driving mechanism 1 further includes a second spring 16, which is arranged between the vertical plate 132 and the fixed block 60 at the front end of the bottom plate 10. Specifically, the second spring The upper end of 16 is sleeved on the upper guide shaft 1321 at the lower end of the vertical plate 132, and the lower end of the second spring 16 is sleeved on the lower guide shaft 601 at the upper end of the fixed block 60. The spring 16 and the second spring 16 can support the moving rod 13 so as to make the moving rod 13 more stable during the movement, thereby making the adjustment block 20 more stable during the movement.

Embodiment 3

[0051] Such as figure 2 As shown, on the basis of the second embodiment, the lower end of the operating rod 11 has a drive rod 111, and the lower end of the drive rod 111 is provided with an operating ring 112. Since the drive rod 111 and the operating ring 112 are provided, it is convenient to align The operating lever 11 is operated to cause a directional swing.

Abstract

The invention discloses a falling prevention device of a material lifting machine. The falling prevention device of the material lifting machine comprises a base plate. An adjusting block is arrangedat the front end of the base plate, and a leaf spring is arranged at the upper end of the adjusting block. An adjusting mechanism is arranged at the lower end of the adjusting block and can drive theadjusting block to move up and down between a pair of guide plates located at the front end of the adjusting block. According to the falling prevention device of the material lifting machine, due to the fact that the structure is adopted, the position of the adjusting block can be accurately adjusted, the adjusting block can also be reliably connected to the base plate, and the falling preventiondevice of the material lifting machine is conveniently used.

Description

Technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-falling device for a material hoist. Background technique [0002] The material hoist is a kind of mechanical conveying equipment with a fixed device. It is mainly suitable for continuous vertical lifting of powder, granular and small materials. It is equipped with a rope break protection safety device, a parking safety device, a buffer device, upper and lower heights and limit limits. Safety protection devices such as safety devices and anti-loosing rope devices. [0003] Chinese patent CN00242437.1 discloses an anti-fall protector for a material hoist, which includes a bottom plate, a guide device and an elastic device. The bottom plate is equipped with a guide rail and a guide rail. The guide rail and the guide rail have an angle α with the vertical direction. The sliding block and the sliding block are respectively installed, and the sliding block and the slid...
