Abstract
The invention discloses a tow tractor capable of limiting for a draw gear traction frame. The tow tractor comprises a tow tractor main body, which is provided with the draw gear traction frame capable of moving up and down, wherein the draw gear traction frame is controlled by an oil cylinder; the tow tractor main body is provided with a limit switch, which is above the draw gear traction frame; when the draw gear traction frame is lifted to a limiting part, the limit switch is touched, and a power circuit is switched off, so that the oil cylinder is stopped, and the lifting of the draw gear traction frame is stopped; the rear part of the tow tractor main body is provided with a sliding rail; and the draw gear traction frame is capable of moving on the sliding rail. According to the tow tractor capable of limiting for the draw gear traction frame disclosed by the invention, when the draw gear traction frame is lifted, the lifting of the draw gear traction frame can be automatically stopped, so that the workload of workers is reduced; and the lifting stop part is uniform, so that working efficiency is improved.
Description
Technical field
The present invention relates to a kind of tractor truck, refer in particular to a kind of tractor truck with hook drawbar frame of limit function.
Background technology
Along with the fast development of modern logistics, the propelling of enterprise automation process, work efficiency improves step by step, and tractor truck is used in enterprises widely as a kind of handbarrow, and it is provided and delivered efficiently, satisfies enterprise's running production rapidly and efficiently fully.Concrete spacing of the tractor truck neither one of present employed hook traction posture, in use, need the manual control switch to realize the rising of hook drawbar frame is stopped, this has increased the weight of workman's work load, and the rising of linking up with drawbar frame is stopped the position being not easy to hold, affect work efficiency.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of tractor truck with hook drawbar frame of limit function.
For achieving the above object, the technical solution used in the present invention is: a kind of tractor truck with hook drawbar frame of limit function, comprise the tractor truck body, and the rear portion of described tractor truck body is provided with hook drawbar frame moving up and down; Described hook drawbar frame is controlled by oil cylinder; Described tractor truck body is provided with limit switch, is positioned at the top of hook drawbar frame; Described hook drawbar frame rises to spacing place, runs into described limit switch, and interrupting power circuit quits work oil cylinder, and then the hook drawbar frame stops to rise.
Preferably, the rear portion of described tractor truck body is provided with slide rail; Described hook drawbar frame can be mobile at slide rail.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
The tractor truck of the present invention program's the hook drawbar frame with limit function because described tractor truck body is provided with limit switch, is positioned at the top of hook drawbar frame; Described hook drawbar frame rises to spacing place, runs into described limit switch, and interrupting power circuit quits work oil cylinder, and then the hook drawbar frame stops to rise.Tractor truck with hook drawbar frame of limit function of the present invention in the process of enhancing hook drawbar frame, can be realized stopping automatically rising, and has reduced workman's work load, and the position unification of rising and stopping, and has improved work efficiency.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the block diagram of the tractor truck of the hook drawbar frame with limit function of the present invention;
Accompanying drawing 2 is the spacing fundamental diagram of the tractor truck of the hook drawbar frame with limit function of the present invention;
Wherein: 1, tractor truck body; 2, hook drawbar frame; 3, limit switch; 4, slide rail.
The specific embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1,2 is a kind of tractor truck with hook drawbar frame of limit function of the present invention, comprises tractor truck body 1, and the rear portion of described tractor truck body 1 is provided with by oil cylinder and controls hook drawbar frame 2 moving up and down; Described hook drawbar frame 2 is controlled by oil cylinder; Described tractor truck body 1 is provided with limit switch 3, is positioned at the top of hook drawbar frame 2; Described hook drawbar frame 2 rises to spacing place, runs into described limit switch 3, interrupting power circuit, and motor quits work, and motor-driven oil pump also quits work, and oil cylinder is quit work, and then hook drawbar frame 2 stops to rise; The rear portion of described tractor truck body 1 is provided with slide rail 4; Described hook drawbar frame 2 can be mobile at slide rail 4.
Tractor truck with hook drawbar frame of limit function of the present invention in the process of enhancing hook drawbar frame 2, can be realized stopping automatically rising, and has reduced workman's work load, and the position unification of rising and stopping, and has improved work efficiency.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
