Description
Technical field
The utility model relates to a kind of jacking system.
Background technology
Vehicle-carrying lifting machine is that jacking system is arranged on to the aerial lift device on automobile, existing jacking system can be divided into crossing type lifting apparatus and crank arm type jacking system, the volume of crossing type lifting apparatus and crank arm type jacking system is all very large, this causes while putting onboard and need to reequip vehicle on the one hand, but law is to the repacking of vehicle, there are strict requirements, and this has also just limited the use of crossing type lifting apparatus and crank arm type jacking system; Be exactly because the volume of crossing type lifting apparatus and crank arm type jacking system is large, Heavy Weight in addition, its driver train is generally hydraulic drive mechanism, need could use after supporting corresponding pumping plant, the use of pumping plant has further increased complex structure degree and the cost of manufacture of these two kinds of jacking systems; In addition, existing jacking system is very not steady yet, and long-time use affects its service life, is not also used in some to using in the high moral occasion of lifting process smoothness requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of jacking system simple in structure.
In order to address the above problem, the technical solution of the utility model is:
A kind of jacking system, comprise base, on base, be provided with at least two vertical guideposts of arranging, the slidable fit that leads on described guidepost has lifting support, on base, rotate and be provided with the screw mandrel be arrangeding in parallel with described guidepost, on screw mandrel, be provided with the moment of torsion input section for moment of torsion input, screw mandrel and described lifting support screwed connection to make lifting support move linearly along screw mandrel in the time that screw mandrel rotates.
Described guidepost has three, and on the cross section perpendicular to vertical, the axis of three guideposts forms three summits of equicrural triangle.
Described screw mandrel is positioned on the Huo Yao limit, base of described equicrural triangle.
The top of described guidepost is installed with footstock, and the top of described screw mandrel is rotated and is assemblied on described footstock.
On described base, be also provided with drive motor, the power take-off shaft of described drive motor is in transmission connection by the moment of torsion input section of transmission device and described screw mandrel.
On described base and footstock, be respectively arranged with the limit switch with described drive motor control linkage.
The beneficial effects of the utility model are: screw mandrel and lifting support have formed leading screw, screw mechanism, input the upper input torque of section to the moment of torsion of screw mandrel in use, screw mandrel rotates, lifting support will do straight line lifting action along screw mandrel, it is steady that guidepost is conducive to the lifting of lifting support, whole jacking system simple in structure, and take small volume, easy to carry and transport.

Detailed description of the invention
A kind of embodiment of jacking system is as shown in Fig. 1 ~ 4: comprise base 2, on base, be provided with three vertical guideposts 4 of arranging, on the cross section perpendicular to vertical, the axis of three guideposts forms three summits of equicrural triangle, the top of guidepost is installed with the slidable fit that leads on 1, three guidepost of footstock lifting support 3.On base, be rotatably equipped with the screw mandrel 7 be arrangeding in parallel with guidepost, screw mandrel is positioned on the base of equicrural triangle, the top of screw mandrel and footstock normal-running fit, the bottom of screw mandrel is provided with the moment of torsion input section for moment of torsion input, and lifting support and screw mandrel screwed connection to make lifting support move linearly along screw mandrel in the time that screw mandrel rotates.On base, be also provided with drive motor 6, the power take-off shaft of drive motor is in transmission connection by transmission device 5 and the moment of torsion input section of screw mandrel, transmission device is turbine and worm transmission device, the turbine of turbine and worm transmission device is coaxially fixedly arranged on the moment of torsion of screw mandrel and inputs section above, and the worm screw of turbine and worm transmission device and the power take-off shaft of drive motor are in transmission connection.On base and footstock, be respectively arranged with the limit switch 8 with drive motor control linkage.
When use, drive motor drives screw mandrel to rotate by transmission device, and screw mandrel and lifting support have formed screw-nut mechanism, in the time that screw mandrel rotates, lifting support can be along screw mandrel oscilaltion campaign, and in the time that lifting support touches corresponding limit switch, limit switch control drive motor quits work.Three guideposts are equicrural triangle and distribute, and can be conducive to the steady lifting of lifting support, can ensure again the stability of whole jacking system skeleton; Screw mandrel is positioned on the base of equicrural triangle, be conducive to middle part for jacking system remaining go out working space.In other embodiment of the present utility model: the number of guidepost can also be three, four or more; Screw mandrel can also be positioned on the waist limit of equicrural triangle, and screw mandrel also can be positioned at equicrural triangle inside or outside certainly; Moment of torsion input section can also be arranged at the top of screw mandrel, and now drive motor can be arranged on footstock; Certainly footstock also can not established; Each limit switch also all can not established; Transmission device can also be gear drive, gear drive comprises the first gear of being coaxially fixedly arranged on screw mandrel and the second gear with the first meshed transmission gear, the power take-off shaft of the second gear and drive motor is in transmission connection, and transmission device can also be chain drive; Drive motor and transmission device can not be also the parts of this jacking system, such as drive motor and transmission device are as outsourcing piece, just drive motor and transmission device are assemblied on jacking system in use.
