Abstract
The utility model discloses a hydraulic elevation device of traction base of traction automobile, which comprises a rocking arm and a hydraulic cylinder. One end of the rocking arm is fixed on a vehicle frame of a traction automobile by a rotary shaft, another end of the rocking arm is fixedly connected with a traction base; a ball joint on two ends of the hydraulic cylinder respectively, an upper ball joint is fixedly connected with the rocking arm by a ball joint base, a lower ball joint is connected with a fixing device on the vehicle frame by a ball joint base; a left giude limit plate and a right guide limit plate are arranged on the vehicle frame at two sides of the traction automobile; a lower limit elastic pad is arranged on the vehicle frame below the rocking arm. When the traction automobile is separated from the semi-trailer, the driver controls a handle in a cab, the hydraulic cylinder is driven by a power take-off, a transmission shaft and a hydraulic pump so as to rise the rocking arm, separation between the traction automobile and the semi-trailer can be realized conveniently in this way. When coupling between the traction automobile and the semi-trailer is required, the rocking arm is dropped by the hydraulic cylinder. The utility model reduces labor strength of the driver, and has advantages of rational design, simple structure, flexible operation, convenient use and improved working efficiency greatly.
Description
(1) technical field
The utility model relates to a kind of jacking system, particularly a kind of wheel tractor traction seat hydraulic lift.
(2) background technology
The traction seat of existing wheel tractor is stationary structure, promptly captives joint with vehicle frame.Its technological deficiency is that when tractor truck separated with superimposed trailer, the hydraulic ram that chaufeur must be handled superimposed trailer earlier landed it, and then handles tractor truck and separate with superimposed trailer; When needing tractor truck and superimposed trailer to articulate, at first handle tractor truck and superimposed trailer articulates, the hydraulic ram of handling superimposed trailer is raised to the height that does not influence automobile normal running away from ground again.This structure makes separating of tractor truck and superimposed trailer and articulates, and is very numerous and diverse, is not suitable for the operating mode that tractor truck and superimposed trailer frequently articulate especially.
(3) summary of the invention
For overcoming the defective of prior art, the utility model provides a kind of reasonable in design, simple in structure, flexible operation, easy to use, the wheel tractor traction seat hydraulic lift of increasing work efficiency greatly.
A kind of wheel tractor traction seat hydraulic lift is made up of swing arm and hydraulic actuating cylinder, and swing arm one end is fixed on by axis of revolution on the vehicle frame of tractor truck, and the other end is captiveed joint with traction seat; Respectively there is a bulb at the hydraulic actuating cylinder two ends, and last bulb is captiveed joint with swing arm by ball cap, and following bulb is connected with anchor fitting on the vehicle frame by ball cap.
The vehicle frame of swing arm both sides is provided with left and right sides guide and limit sheet.
The vehicle frame of swing arm below is provided with the lower limit cushion.
When tractor truck separated with superimposed trailer, chaufeur was handled control handle at operator's compartment, promoted hydraulic actuating cylinder by power takeoff, transmission shaft and Hydraulic Pump, and swing arm is risen, and can realize separating of tractor truck and superimposed trailer easily.When needing tractor truck and superimposed trailer to articulate, by hydraulic actuating cylinder swing arm is fallen and to get final product.Alleviate the labour intensity of chaufeur, improved work efficiency.
The utlity model has reasonable in design, simple in structure, flexible operation, easy to use, the characteristics of increasing work efficiency greatly.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1, tractor chassis, 2, traction seat, 3, power takeoff, 4, oil pump, 5, fuel tank, 6, hydraulic actuating cylinder, 7, ball cap, 8, swing arm, 9, axis of revolution, 10 guide and limit sheets, 11, the lower limit cushion, 12, control cock, 13, control handle.
(5) specific embodiment
Embodiment: structure of the present utility model is made up of swing arm 8 and hydraulic actuating cylinder 6 as shown in Figure 1, and swing arm 8 one ends are fixed on the vehicle frame of tractor truck 1 by axis of revolution 9, and the other end is captiveed joint with traction seat 2; Respectively there is a bulb at the two ends of hydraulic actuating cylinder 6, and last bulb is captiveed joint with swing arm 8 by ball cap 7, and following bulb passes through on ball cap 7 and the vehicle frame 1 anchor fitting and is connected.The vehicle frame 1 of swing arm 8 both sides is provided with left and right sides guide and limit sheet 10, and the vehicle frame 1 of swing arm 8 belows is provided with lower limit cushion 11.
Claims (3)
1, a kind of wheel tractor traction seat hydraulic lift is characterized in that, is made up of swing arm and hydraulic actuating cylinder, and swing arm one end is fixed on by axis of revolution on the vehicle frame of tractor truck, and the other end is captiveed joint with traction seat; Respectively there is a bulb at the hydraulic actuating cylinder two ends, and last bulb is captiveed joint with swing arm by ball cap, and following bulb is connected with anchor fitting on the vehicle frame by ball cap.
2, wheel tractor traction seat hydraulic lift as claimed in claim 1 is characterized in that, the vehicle frame of described swing arm both sides is provided with left and right sides guide and limit sheet.
