Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the crawler lift vehicle of the present invention will be described in further detail.

[0023] figure 1 The overall layout plan diagram of the crawler lift vehicle of the present invention is given, including a battery 1, an engine 2, a hydraulic oil tank 3, a hydraulic valve group 4, a working platform 5, a lifting mechanism 6, a hydraulic pump 7, a traveling mechanism 8, and a hydraulic motor 9 .

[0024] Described walking mechanism 8 is made up of rubber track, driving wheel, guide wheel, track roller, supporting pulley and hydraulic motor 9. After the engine 2 is started, the power is transmitted to the reducer through the V-belt, and the torque decelerated by the reducer is directly output to the hydraulic pump 7, and the hydraulic pump 7 converts mechanical energy into hydraulic energy and transmits it to the hydraulic motor through the hydraulic oil pipe and the hydraulic valve group 4 9, thus driving the hydraul...

Abstract

The present invention designs a crawler-type lifting vehicle, which adopts a hydraulically driven crawler-type walking chassis, and realizes the forward, backward and turning of the vehicle by controlling the rotating speed of the left and right hydraulic motors. Its lifting platform is composed of a scissor-type lifting mechanism and a telescopic work platform. The lifting is driven by a hydraulic cylinder. The independent pump is used to realize the operation of platform lifting and farm tool lifting, which achieves the purpose of energy saving and solves the problem of single oil pump oil supply making the walking power Insufficient problem.

Description

Technical field [0001] The invention relates to a semi-automatically controlled and hydraulically driven crawler lift vehicle. Background technique [0002] At present, in gardening operations, the degree of mechanization is not high, and most of the work is done by manpower. Even if most of the machines in use are general-purpose machines, these machines have single functions and require a variety of different machines to complete the work. Moreover, the existing mechanical walking adopts mechanical drive, which is cumbersome, laborious, and inefficient to shift gears, and the mechanical controllability and comfort are not good. personnel poses personal safety concerns. Contents of the invention [0003] In order to solve the problems of poor maneuverability of mechanically driven work vehicles and difficulty in realizing stepless speed change, the present invention designs a hydraulically driven crawler-type work vehicle, which can not only realize semi-automatic contro...
