Abstract
The invention relates to a worm and gear type lifting platform. The worm and gear type lifting platform comprises a pedestal and an end cover; the end cover is arranged above the pedestal; a round hole is formed in the upper head face of the pedestal; a vertically arranged rotating shaft is arranged in the round hole; a worm and a worm gear arranged horizontally and engaged to each other are arranged at the joint between the pedestal and end cover; the worm gear is arranged on the rotating shaft in an interference fit mode, and one end of the worm extends out of the pedestal; the end cover is provided with a workbench capable of moving up and down; the upper end of the rotating shaft is in threaded connection with the workbench. When working, through rotating a hand wheel, the worm drives the worm gear to rotate so as to drive the rotating shaft to rotate, and the rotating shaft enables the workbench to move up and down through threaded transmission. The worm rotates by a scale according to the worm and gear transmission ratio and threaded transmission pitch through manual regulation, the workbench ascends or descends a little to achieve precise regulation, and the cost is low.
Description
Technical field
The present invention relates to lifting field, refer in particular to a kind of Worm-gear type bay-lift.
Background technology
In an experiment, often need the accurate height regulating object, and now drive screw nut driving by stepping motor in the art, thus drive the accurate up-and-down movement of bay-lift; Due to the up-and-down movement by step motor control bay-lift, cause cost higher, and cannot use under power down mode, cause unnecessary loss, for this reason, we have developed a kind of Worm-gear type bay-lift of manual regulation, and accurately mobile, with low cost.
Summary of the invention
The present invention seeks to furnish us with to overcome the deficiencies in the prior art the Worm-gear type bay-lift that have developed a kind of manual regulation, and accurately mobile, with low cost.
For achieving the above object, the technical solution used in the present invention is: a kind of Worm-gear type bay-lift, comprises base, end cap; Described end cap is arranged on the top of base; The upper surface of described base is provided with circular hole; The rotating shaft vertically arranged is provided with in described circular hole; The junction of described base and end cap is provided with and is horizontally disposed with and the worm screw be meshed and turbine; Described turbine interference fit be arranged in rotating shaft, one end protuberate basic unit of worm screw; Described end cap is provided with bench board moving up and down; Upper end and the bench board of described rotating shaft are threaded; Operationally, rotate handwheel, worm screw drives turbine rotation, thus drives axis of rotation, and rotating shaft makes bench board move up and down by screw-driven.
Preferably, the bottom of described bench board is provided with annular groove; The medial surface of described annular groove is provided with screw thread; The upper end of described rotating shaft is provided with tapped bore; The described tapped bore of rotating shaft upper end is threaded with the medial surface of annular groove.
Preferably, the side of described bench board is provided with scale mark.
Preferably, one end of described worm screw protuberate basic unit is provided with handle.
Preferably, one end of described worm screw protuberate basic unit is provided with handwheel; Described handwheel is provided with scale.
Preferably, the lower end of described rotating shaft is connected with the bottom of circular hole by bearing.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Worm-gear type bay-lift of the present invention manually regulates and worm screw can be made to turn a scale according to the pitch of the transmitting ratio of worm and gear and screw-driven, and bench board rises or declines one, reaches fine adjustment, and with low cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the birds-eye view of Worm-gear type bay-lift of the present invention;
Accompanying drawing 2 is the cutaway view of A-A in Fig. 1;
Wherein: 1, base; 2, end cap; 3, worm screw; 4, turbine; 5, bench board; 6, rotating shaft; 7, bearing; 8, handwheel.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1-2 is Worm-gear type bay-lift of the present invention, comprises base 1, end cap 2; Described end cap 2 is arranged on the top of base 1, and is connected by screw; The upper surface of described base 1 is provided with circular hole; The rotating shaft 6 vertically arranged is provided with in described circular hole; The lower end of described rotating shaft 6 is connected with the bottom of circular hole by bearing 7; The junction of described base 1 and end cap 2 is provided with and is horizontally disposed with and the worm screw 3 be meshed and turbine 4; Described turbine 4 interference fit be arranged in rotating shaft 6, one end protuberate basic unit 1 of worm screw 3 is also provided with handwheel 8 or handle; Described handwheel 8 is provided with scale; Described end cap 2 is provided with bench board 5 moving up and down; The side of described bench board 5 is provided with scale mark, and bottom is provided with annular groove; The medial surface of described annular groove is provided with screw thread; The upper end of described rotating shaft 6 is provided with tapped bore; The tapped bore of described rotating shaft 6 upper end is threaded with the medial surface of annular groove; Operationally, rotate handwheel 8, worm screw 3 drives turbine 4 to rotate, thus drives rotating shaft 6 to rotate, and rotating shaft 6 makes bench board 5 move up and down by screw-driven.
In use: first make handwheel 8 turns of scales according to the transmitting ratio of worm and gear and the pitch of screw-driven, bench board rises or declines one; Rotate handwheel 8, worm screw 3 drives turbine 4 to rotate, thus drives rotating shaft 6 to rotate, and rotating shaft 6 makes bench board 5 move up and down by screw-driven, and very clearly can know that bench board 5 rises altogether or have dropped how many by the scale mark of bench board 5 side.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Worm-gear type bay-lift of the present invention manually regulates and worm screw can be made to turn a scale according to the pitch of the transmitting ratio of worm and gear and screw-driven, and bench board rises or declines one, reaches fine adjustment, and with low cost.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
