Hydraulic elevator device with high safety performance

Abstract

The invention discloses a hydraulic elevator device with high safety performance, and relates to the technical field of hydraulic elevators. The hydraulic elevator device with high safety performancecomprises a movable base, an elevator body, a protection device and a climbing device, wherein the elevator body is fixedly installed on the upper surface of the movable base, the protection device isfixedly installed on the top of the elevator body, and the upper surface of the movable base is in sliding connection with the climbing device. According to the hydraulic elevator device with high safety performance, through arrangement of the protection device, a first electric push rod and second electric push rods can be used for driving a concentric-square-shaped guardrail and a guardrail plate to extend out of the upper portions of a protection plate and a cabinet door correspondingly, so that the concentric-square-shaped guardrail and the guardrail plate form a height-adjustable complete protection guardrail, the guardrail heights corresponding to workers can be selected by fencing rods according to the different workers, so that the workers with different heights are effectively protected, and practicability of the device is improved while safety is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic lifts, in particular to a hydraulic lift device with high safety performance. Background technique [0002] The hydraulic lift mainly realizes the function of lifting through the pressure transmission of hydraulic oil. Its scissor mechanical structure makes the lift have high stability in lifting, and the wide operating platform and high carrying capacity make the range of high-altitude operations wider Large and suitable for multiple people to work at the same time. It makes aerial work more efficient and safer. A hydraulic lift is a liftable machine equipment composed of a walking mechanism, a hydraulic mechanism, an electric control mechanism, and a supporting mechanism. The hydraulic oil is under a certain pressure formed by the vane pump, and enters the lower end of the hydraulic cylinder through the oil filter, explosion-proof electromagnetic reversing valve, throttle valve, hydraulic co...

AI Technical Summary

Problems solved by technology

[0003] 1. In the prior art, when the hydraulic lift is at the lowest position, there is still a certain distance from the ground, and people do not install protective devices during the process of boarding the hydraulic lift. When people are in danger when they board the hydraulic lift, It will cause the back of the human body to contact the ground, thus posing a threat to the personal safety of the human body

[0004] 2. In the prior art, the structure of the protection device of the existing elevator is relatively simple, and the height of the protection device cannot be adjusted according to the user's own situation, which in turn affects the work efficiency of the workers
