Abstract
The invention provides a lifter with a lead screw. The lifter comprises a cabinet, a swing base is arranged on the lower portion of the cabinet, a worm wheel and a worm are arranged in the cabinet and are meshed with each other, the lead screw is arranged in the worm wheel, a lug ring is arranged on the lead screw, a copper sleeve is arranged between the lead screw and the cabinet, a protecting sleeve is arranged at a position, below the copper sleeve, of the lead screw, a guide key is mounted on a cabinet cover, a key groove matched with the guide key is formed in the lead screw, one end of the worm is connected with a motor through a shaft sleeve, and the other end of the worm is connected with an encoder. The lifter has the advantages that one end of the worm is connected with the motor through a motor connecting plate, the other end of the worm is connected with the encoder, the worm drives the worm wheel to rotate, the worm wheel drives the lead screw to move up and down, and the lead screw drives the lug ring to move up and down to achieve functions such as lifting and dropping, the guide key on the lead screw plays a role in guiding, and space of an anti-rotation device is saved; the lifter is compact in structure, small in size, convenient to mount, flexible to use, high in stability, long in service life and the like.
Description
Technical field
The invention belongs to elevator field, especially relate to a kind of screw lift.
Background technology
Screw lift can control to adjust the height promoting or advance by certain procedures exactly, is widely used in the industry-by-industries such as machinery, metallurgy, building, chemical industry.In the process manufacturing steel pipe, need use elevator the machine in jacking frame is promoted, lower degradation operation, in existing technology, there is elevator and take the technical matters such as height that volume greatly, can accurately not control to promote and decline in the complex structure of elevator.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of compact conformation, uses screw lift flexibly, and the jacking frame being particluarly suitable for pipe mill uses.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of screw lift, comprise casing, described lower box is provided with swing seat, worm gear and worm screw is provided with in described casing, described worm gear and worm mesh, screw mandrel is provided with in described worm gear, described screw mandrel is provided with earrings, copper sheathing is provided with between described screw mandrel and casing, the below described screw mandrel being positioned at copper sheathing is provided with protecting sleeve, described casing is provided with case lid, described case lid is provided with feather key, described screw mandrel is provided with the keyway matched with feather key, save the space of anti-rotation device, the effect of guiding can also be played, one end of described worm screw is provided with axle sleeve, described axle sleeve is connected with motor, the other end of described worm screw and coder connect, described coder is arranged on the coder support of the worm screw other end.
Further, described swing seat is disk, and described disk is provided with two support cylinder.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, one end of worm screw is connected with motor by motor tie-plate, the other end of worm screw and coder connect, worm screw drives worm gear to rotate, worm gear drives screw mandrel to move up and down, and screw mandrel drives earrings to move up and down, and completes lifting, lower degradation function, feather key on screw mandrel plays the effect of guiding, saves the space of anti-rotation device; Have compact conformation, volume little, easy for installation, use flexibly, good reliability, stability are high, long service life etc.

Detailed description of the invention
As illustrated in fig. 1 and 2, a kind of screw lift of the present invention, comprise casing 11, described casing 11 bottom is provided with swing seat 4, described swing seat 4 is disk, described disk is provided with two support cylinder, worm gear 3 and worm screw 8 is provided with in described casing 11, described worm gear 3 engages with worm screw 8, screw mandrel 5 is provided with in described worm gear 3, described screw mandrel 5 is provided with earrings 1, copper sheathing 7 is provided with between described screw mandrel 5 and casing 11, the below described screw mandrel 5 being positioned at copper sheathing 7 is provided with protecting sleeve 6, described casing 11 is provided with case lid, described case lid is provided with feather key 2, described screw mandrel 5 is provided with the keyway matched with feather key 2, save the space of anti-rotation device, the effect of guiding can also be played, one end of described worm screw 8 is provided with axle sleeve 9, described axle sleeve 9 is connected with motor, the other end and the coder of described worm screw 8 connect, described coder is arranged on the coder support 12 of worm screw 8 other end.
The working process of this example: during work, one end of worm screw 8 is connected with motor by motor tie-plate 10, the other end of worm screw 8 and coder connect, worm screw 8 drives worm gear 3 to rotate, worm gear 3 drives screw mandrel 5 to move up and down, and screw mandrel 5 drives earrings 1 to move up and down, and completes lifting, lower degradation function, feather key 2 on screw mandrel 5 plays the effect of guiding, saves the space of anti-rotation device.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
