Embodiment Construction

[0016] The present invention is further described and understood by non-limiting examples below.

[0017] like Figure 1-3 As shown, the present invention is an air-source power-driven lift working ladder, which includes a bottom frame 1, which is designed to stick to the ground and has a height above the ground of 80 mm. The top of the bottom frame 1 passes through scissor lifting mechanisms on both sides. 2. The support is equipped with an aluminum lifting platform 3. Compared with the scissor lifting mechanism 2 in the prior art, it is directly arranged under the lifting platform. The design of the supports on both sides strengthens the stability of the platform. The bottom frame 1 and the scissor lifting mechanism 2 Using Q345B material, it has the characteristics of high strength and light specific gravity;

[0018] The scissor lifting mechanism 2 includes a first scissor bar 22 hinged on the top of the bottom frame 1 through a hinge seat, a third scissor bar 24 hinged a...

Abstract

The invention discloses a lifting working ladder driven by air source power, and belongs to a large assembly fixture. The lifting working ladder driven by the air source power comprises a bottom frame, wherein an aluminum lifting platform is supported and installed at the top of the bottom frame through shear fork lifting mechanisms at the two sides; an operation table used for containing a gas-liquid booster pump assembly is arranged at the end part of the aluminum lifting platform; a hydraulic air cylinder assembly used for jacking the aluminum lifting platform is installed on each shear fork lifting mechanism; the hydraulic air cylinder assemblies are connected with the gas-liquid booster pump assembly, and hydraulic power is provided to drive the hydraulic air cylinder assemblies to carry out jacking action. According to the invention, a gas-liquid booster pump is adopted for driving the hydraulic air cylinder assemblies, so that the safety and practicability better meet the requirements, and the practicability of the product is improved; and the shear fork lifting mechanisms are symmetrically arranged at the two sides of the lifting platform, so that the stability of the platform is enhanced.

Description

technical field [0001] The invention relates to the technical field of large-scale assembly frames, in particular to an air source power-driven elevating working ladder. Background technique [0002] The hydraulic system has the advantages of large power-to-weight ratio, easy realization of various transmission movements, good load characteristics, good rapidity, automatic lubrication, and easy automation, etc., and is widely used in the aviation field. The driving of the existing aircraft working ladder lifting is usually realized by the electric drive hydraulic system, and the hydraulic pump is driven by the motor booster to provide the lifting power of the working ladder. This driving method has the following disadvantages: the high-power motor is easy to generate heat and electricity Sparks, there is a danger of electric leakage. Contents of the invention [0003] The object of the present invention is to provide an air source power-driven working lift. [0004] The ...
