Description
Technical field
The utility model relates to a kind of all-hydraulic cableway tractor, is applied to cableway transport.
Background technology
The performance of cableway tractor directly determines the conveying efficiency of provisional built on stilts freight ropeway, and existing cableway tractor is generally converted by motor-driven grinding mill, and price is lower, but tractive output is little, and deceleration and stopping performance is bad, during operation, heating is large, speed is low, and fault rate is very high.Existing hydraulic pressure cableway tractor is integrated, belt-driving, the traction of single cylinder, and braking is general, and tractive force is maximum is only 1.5t, cannot meet the traction requirement of heavily loaded cableway.
Utility model content
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of all-hydraulic cableway tractor.
The technical solution of the utility model is:
A kind of all-hydraulic cableway tractor, comprises power system, hydraulic efficiency pressure system, traction system that split is arranged, it is characterized in that:
Described power system comprises by driving engine and HM Hydraulic Motor; Described hydraulic efficiency pressure system comprises engine-driven hydraulic variable displacement pump, described hydraulic variable displacement pump is in order to drive HM Hydraulic Motor, between HM Hydraulic Motor and hydraulic variable displacement pump, be provided with high-pressure overflow valve, described traction system comprises the hitch wheel driven through reductor by HM Hydraulic Motor.
Wherein, also comprise the control system that split is arranged, described control system comprises controlling power system, hydraulic efficiency pressure system, the pressure-gradient control valve of traction system, directional control valve.
Described high-pressure overflow valve is provided with compression indicator.
Connect dish by flange between described driving engine and hydraulic variable displacement pump to connect.
The utility model has the advantage of: the utility model stepless change, transmission is simple, and hydraulic braking is reliable, simple to operate; Continuous tractive effort is large, and haulage speed is high, meets the traction requirement of heavily loaded cableway.
Accompanying drawing explanation
Fig. 1 the utility model embodiment control module block diagram.
Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
With reference to figure 1, the utility model relates to a kind of all-hydraulic cableway tractor, and comprise power system, hydraulic efficiency pressure system, traction system that split is arranged, described power system comprises by driving engine and HM Hydraulic Motor; Described hydraulic efficiency pressure system comprises engine-driven hydraulic variable displacement pump, described hydraulic variable displacement pump is in order to drive HM Hydraulic Motor, between HM Hydraulic Motor and hydraulic variable displacement pump, be provided with high-pressure overflow valve, described traction system comprises the hitch wheel driven through reductor by HM Hydraulic Motor.
Also comprise the control system that split is arranged, described control system comprises controlling power system, hydraulic efficiency pressure system, the pressure-gradient control valve of traction system, directional control valve.
Above-mentioned high-pressure overflow valve is provided with compression indicator.
Connect dish by flange between above-mentioned driving engine and hydraulic variable displacement pump to connect.
In implementation process, driven by engine hydraulic variable displacement pump rotates, and to hydraulic efficiency pressure system pressure oil output, drives HM Hydraulic Motor to rotate; HM Hydraulic Motor drives hitch wheel to carry out towage by reductor.High-pressure overflow valve for setting up the delivery pressure of hydraulic variable displacement pump, and is shown by compression indicator.The size of hydraulic system working pressure depends on the size of load.The friction force that the traction resistance that load depends primarily on hitch wheel overcomes with it, and the on-way resistance that fluid flows in pipeline.Load is larger, and system pressure is higher.The maximum working pressure (MWP) of hydraulic efficiency pressure system adjusts by high-pressure overflow valve, when the pressure adjusting of by pass valve is after a certain numerical value, the tractive force limit that the maximum working pressure (MWP) of system and equipment can bear just determines, as long as therefore regulate high-pressure overflow valve pressure, and just can stepless control tractive force limit.When equipment works below tractive force limit, HM Hydraulic Motor oil inlet and outlet difference of pressure also below maxim according to tractive force size respective change.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
