Problems solved by technology
[0006] The random drive system device of the hydraulic pump with the above structure realizes the random linkage between the hydraulic pump and the actuator (hydraulic pipe wrench) when in use. When the hydraulic pipe wrench works, the hydraulic pump works, and when the hydraulic pipe wrench stops working, the hydraulic pump simultaneously Stop working, so as to solve the unnecessary increase of the engine load and fuel consumption of the working machine caused by the inability of the original drive device to realize the random linkage between the hydraulic pump and the hydraulic pipe wrench, the accelerated damage of the hydraulic pump and the hydraulic pump drive device, and the hydraulic oil Problems such as failure and leakage, accelerated aging of auxiliary hydraulic components, etc., reduce the ineffective loss of operating machine fuel and hydraulic oil, and save the cost of frequent replacement of hydraulic pumps and their driving devices

Embodiment Construction
[0009] The specific structure and working principle of the present invention are illustrated below in conjunction with the embodiments given in the accompanying drawings.
[0010] As shown in Figure 2, the hydraulic pump random drive system device of the present invention has a hydraulic pump (10), and the hydraulic pump passes through the hydraulic pipeline (17) through the hydraulic motor (14) in the pipe wrench control valve (13) and the hydraulic pipe wrench. ), the overflow valve (12) is connected to the hydraulic pump through the hydraulic pipeline, and the operating handle (20) hinged on the pipe wrench control valve (13) is also hinged with one end of the linkage arm (19). The other end of the connecting arm is hinged together with the movable contact (18-1) of the normally open double contact switch (18), and the movable contact of the normally open double contact switch is connected to the positive pole of the power supply through the lead (16). The contact point (18...

The invention provides a hydraulic pump driving randomly system. There is hydraulic pump getting across hydraulic pipeline and then connecting with hydraulic motor in hydraulic socket wrench according to manipulative valve of socket wrench. Operating handle hinging the manipulative valve hinges one end of the linkage arm, the other end of which hinges moving contact of normally open switch with double contacts. The moving contact of the normally open switch connects with anode of electrical source while fixing contact with anode of electromagnetic clutch. The electromagnetic clutch whose shell is grounded according to bonding is fixed between output axis of transimisson of the operating machine and the hydraulic pump. The use of the invention device realizes linkage with randomicity of the hydraulic pump and executive units thereby settling problems such as meaningless increase of charge and oil consume of motor of the operating machine brought as existing driving device cannot realize linkage with randomicity, quickening damage of the hydraulic pump and its driving device, invalidation and lose of hydraulic oil, quickening aging of the assistant hydraulic parts and so on.
Description
[0001] technical field [0002] The invention provides a hydraulic pump driving device, in particular a hydraulic pump driving device used on a working machine in the crude oil exploitation industry. Background technique [0003] At present, the hydraulic pipe wrench driven by the operating machine is widely used in the crude oil extraction industry, which is used for loading and unloading oil pipes during drilling and major and minor repairs of oil wells. The hydraulic pipe wrench is powered by a hydraulic pump driven by a working machine. Due to the current drive system device, the hydraulic pump cannot be linked randomly with the actuator (hydraulic pipe wrench), so that most of the time the hydraulic pump is in a long-term position with the medium and high-speed operation of the working machine engine except for effective work. Ineffective operation under pressure for a long period of time will not only cause accelerated damage to...
