Embodiment 1

[0016] A cab hydraulic lifting device, such as figure 1 , figure 2 As shown, it includes two electric pumps 1 connected in parallel and manual pump 2 connected in series with electric pump 1, which greatly reduces the hydraulic pulsation of the system, makes the actuator run more smoothly, and has a larger flow rate, thereby greatly shortening the turning time of the cab and saving The time required for cab overturning maintenance improves the work efficiency. The electric pump 1 and the manual pump 2 are connected by the oil pipe 3. The oil pipe 3 is made of stainless steel pipe, which is easy to form, suitable for making pipelines of different shapes, and has strong weather resistance , strong rust resistance, high strength, high fatigue resistance, the electric pump 1 is equipped with a motor 4 connected to the electric pump 1, the motor adopts 24V voltage, permanent magnet DC motor, low noise, waterproof and dustproof, high speed and overheating Protection function, high...

Abstract

The invention relates to the technical field of automobile cab lifting and discloses a cab hydraulic lifting device. The cab hydraulic lifting device comprises two parallel-connected electric pumps and manual pumps in series connection with the electric pumps. The electric pumps and the manual pumps are connected through oil pipes. The electric pumps are provided with motors connected with the electric pumps. The electric pumps are provided with first check valves connected with the electric pumps. Second built-in check valves are arranged in the manual pumps. The electric pumps are further provided with relays connected with the electric pumps. The relays are magnetic relays. Sockets and switches are connected to the relays correspondingly. The switches are toggle switches. The electric pumps are provided with overflow valves in parallel connection with the electric pumps. The manual pumps are provided with overflow valves connected with the manual pumps. According to the cab hydraulic lifting device, the time need by cab lifting is shortened by one time and lowered to 15 s from original 30 s, the work efficiency is improved greatly, and the automobile maintenance time is saved.

Description

technical field [0001] The invention relates to the technical field of lifting a cab, in particular to a hydraulic lifting device for a cab. Background technique [0002] The performance requirements of the hydraulic lift pump for the cab are very important, which involves the realization of product functions, whether the cab can be lifted and how fast it can be lifted, and even the life safety of the operator. At present, the electrohydraulic lifting oil pump of the cab tilting system generally adopts a single electric lifting oil pump. When the vehicle power supply is out of power and the electric pump is damaged, the electric pump will lose its working function and can no longer provide power to the tilting system. hydraulic kinetic energy. Contents of the invention [0003] The invention aims at the disadvantages of the prior art, and provides a hydraulic lifting device for a driver's cab which is easy to use and quick to lift. [0004] In order to solve the above te...
