Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, specifically a fall-prevention forklift lifting platform. Background Technology

[0002] The lifting platform is a type of lifting equipment composed of a traveling mechanism, a hydraulic mechanism, an electric control mechanism, and a support mechanism. Hydraulic oil is pressurized by a vane pump and passes through an oil filter, an explosion-proof solenoid directional valve, a throttle valve, a hydraulic check valve, and a balance valve before entering the lower end of the hydraulic cylinder. This causes the piston in the cylinder to move upward, lifting the load. Oil returning from the upper end of the cylinder flows back to the oil tank through the explosion-proof solenoid directional valve. The rated pressure is adjusted by a relief valve, and the pressure is observed through a pressure gauge.

[0003] Application number CN201921576319.3 discloses a fall-prevention scissor lift, including a movable base, a scissor lift arm, and a work platform. Through this method, the fall-prevention scissor lift provided by this utility model, by installing ropes on a fixed pole, allows workers to secure the ropes around their waist while working at height, thereby preventing falls and improving safety. However, in practical use, this application has a problem: although the ropes can prevent workers from falling to the ground, they cannot prevent workers from colliding with the scissor lift arm while being pulled by the ropes, resulting in varying degrees of injury to the workers. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A fall-prevention forklift includes a lifting mechanism and a fall-prevention mechanism. The lifting mechanism includes a lift body, a plurality of crossbar sleeves disposed on the top of the lift body, and a guard rod connecting the lift body and the plurality of crossbar sleeves. The fall-prevention mechanism includes a pull rope that slides through the crossbar sleeves, a cylinder disposed on the outside of the crossbar sleeves and connected to the pull rope, a waist sleeve disposed between the plurality of pull ropes, and an arc-shaped rod connecting the pull ropes and the waist sleeve.

[0007] By adopting the above technical solution, in the event of a fall, the multiple pull ropes working together can firmly hold the worker, and ensure that the worker's fall position is always close to the outside of the guardrail. This allows the fallen worker to climb back onto the platform of the elevator body on their own after regaining their composure, thus improving operational safety.

[0008] In a preferred embodiment, this utility model can be further configured such that: multiple pull ropes are of equal length, and the length of the pull ropes is equal to one-half the length of the main platform of the elevator.

[0009] In a preferred embodiment, the present invention can be further configured such that: the inside of the cylinder is hollow, the cylinder is made of metal material, and the diameter of the cylinder is larger than the diameter of the pull rope.

[0010] In a preferred embodiment, the present invention can be further configured such that the waistband is made of nylon material.

[0011] In a preferred embodiment, the present invention can be further configured such that a gate is movably mounted on the guardrail, and the gate is made of the same material as the guardrail.

[0012] In a preferred embodiment, the present invention can be further configured such that: the bottom end of the guard rod is fitted with multiple reinforcing sleeves, and the multiple reinforcing sleeves are all fixedly connected to the top of the elevator body.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, when a worker wearing a waist harness falls, the multiple pull ropes work together to firmly pull the worker, and ensure that the worker's fall position is always close to the outside of the guardrail. This allows the worker to climb back onto the platform of the elevator body after regaining their composure, thus improving work safety.

[0015] 2. In this utility model, the worker opens the gate and enters the platform of the elevator body. Then, he puts on the waist belt to complete the preparation work. After that, he controls the extension of the scissor lift arm of the elevator body to provide conditions for high-altitude work. The length design of the pull rope allows the worker to reach any position on the platform of the elevator body, which not only ensures the safety of the worker, but also does not hinder the worker's high-altitude work.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a fall-prevention forklift lift.

[0027] Example 1:

[0028] Combination Figure 1-3 As shown, the present invention provides a fall-prevention forklift lift, including a lifting mechanism 100 and a fall-prevention mechanism 200. The lifting mechanism 100 includes a lift body 110, a plurality of cross rod sleeves 120 disposed on the top of the lift body 110, and a guard rod 130 connecting the lift body 110 and the plurality of cross rod sleeves 120.

[0029] The fall protection mechanism 200 includes a pull rope 210 that slides through the crossbar sleeve 120, a cylinder 220 located outside the crossbar sleeve 120 and connected to the pull rope 210, a waist sleeve 230 located between multiple pull ropes 210, and an arc-shaped rod 240 connecting the pull ropes 210 and the waist sleeve 230.

[0030] Furthermore, the multiple pull ropes 210 are of equal length, and the length of the pull rope 210 is equal to half the length of the platform of the elevator body 110. The length design of the pull rope 210 allows the worker wearing the waist belt 230 to easily reach any position on the platform of the elevator body 110, which facilitates the worker's work.

[0031] Furthermore, the cylinder 220 is hollow inside and made of metal. The diameter of the cylinder 220 is larger than the diameter of the rope 210. The structural design of the cylinder 220 will not put too much load on the worker. The use of metal material ensures its rigidity, so that the worker can firmly hold the cross bar sleeve 120 when falling.

[0032] Furthermore, the waist support 230 is made of nylon material, and the nylon waist support 230 can be firmly worn around the worker's waist.

[0033] Example 2:

[0034] Combination Figure 1 As shown, based on Embodiment 1, a gate 300 is movably installed on the guardrail 130. The gate 300 is made of the same material as the guardrail 130. The gate 300 facilitates the operator's access to the platform of the elevator body 110.

[0035] Example 3:

[0036] Combination Figure 1-2 As shown in the above embodiment, the bottom end of the guard rod 130 is fitted with a plurality of reinforcing sleeves 400, and the plurality of reinforcing sleeves 400 are all fixedly connected to the top of the elevator body 110. The installation of the reinforcing sleeves 400 can improve the installation firmness of the guard rod 130 and the platform of the elevator body 110.

[0037] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the worker opens the gate 300 and enters the platform of the elevator body 110. Then, the worker puts on the waist belt 230, thus completing the preparation work. After that, the scissor-type lifting arm of the elevator body 110 is extended to provide conditions for high-altitude operations. The length design of the pull rope 210 allows the worker to reach any position on the platform of the elevator body 110. When the worker falls, the pull ropes 210 in multiple directions work together to tighten the worker's body, effectively controlling the worker's fall height. Under the limitation of the waist belt 230, the worker will only stick to the outside of the guardrail 130, so that the worker can climb back to the platform of the elevator body 110 on his own after an accident, effectively improving the safety of use.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
