In order to solve the technical problem, the utility model discloses a technical scheme be:
the utility model provides a well multipurpose jack, includes connecting seat and connecting piece, the connecting seat both ends articulate respectively has the landing leg, and the lower extreme of two landing legs all is equipped with the supporting shoe that couples with the track, the cross-sectional shape of supporting shoe is "n" style of calligraphy, the connecting piece rotates with the connecting seat to be linked, the connecting piece articulates there is the pinch bar, and the one end of pinch bar is equipped with the chain.
And the supporting block is provided with a threaded through hole for connecting with a bolt.
And the supporting block is internally provided with a top block, the top block is connected with the supporting block in a sliding manner, and the top block is pushed to slide through a bolt.
And the connecting seat is provided with a fixed supporting leg.
The connecting piece is rotationally connected with the connecting seat through a bearing.
compared with the prior art, the utility model, the intentional effect that has is:
Through the cooperation of landing leg and supporting shoe, can arrange the ground jack in on the track, utilize lever principle to lift by crane the operation to reach laborsaving purpose. The device has the advantages of simple structure, low manufacturing cost, convenient installation and maintenance, sensitive and reliable action and long service life, and plays an important role in improving the production efficiency, improving the labor condition and guaranteeing the safety production.

Detailed Description
The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the multipurpose well jack comprises a connecting seat 1 and a connecting piece 2, wherein two ends of the connecting seat 1 are respectively hinged with a supporting leg 3, the lower ends of the two supporting legs 3 are respectively provided with a supporting block 4 connected with a track 13, the cross section of each supporting block 4 is n-shaped, and each supporting block 4 can be made of channel steel.
Connecting piece 2 and connecting seat 1 rotate the hookup, and connecting piece 2 articulates there is pinch bar 5, and connecting piece 2 and pinch bar 5 can rotate for connecting seat 1, and the one end of pinch bar 5 is fixed (the welding) has chain 6. Specifically, the method comprises the following steps: the pry bar 5 may be hinged to the link 2 by a hinge shaft.
As shown in FIG. 2, when in use, the two support blocks 4 are respectively placed on the track 13, the pry bar 5 is rotated to move the support blocks to the position above the part to be lifted, the support blocks are connected with the part to be lifted through the chain 6 (specifically: the chain 6 is wound on the part to be lifted or connected with a hook on the part to be lifted), and the other end of the pry bar 5 is pressed downwards to lift the part to be lifted after the connection; after the hoisting, the pry bar 5 is rotated to move the part to be hoisted to the required position.
Further, as shown in fig. 3 and 4, in order to ensure the stability of the connection, the supporting block 4 is provided with a threaded through hole for connecting with the bolt 7; the bolt 7 can be passed through the threaded through-hole against the rail 13.
Further, the bolt 7 directly abuts against the rail 13, which tends to cause a problem of stress concentration. Therefore, as shown in fig. 6 and 7, a top block 8 is provided in the support block 4, and the top block 8 is slidably coupled with the support block 4. The bolt 7 pushes the top block 8 to slide, and the top block 8 abuts against the track 13. The sliding coupling of the top block 8 and the support block 4 can be achieved by various structures, such as: the top block 8 is provided with a slide block 9, and the supporting block 4 is provided with a corresponding chute 10.
Further, as shown in fig. 5, in order to improve the overall stability, the connecting base 1 is provided with a fixed leg 11 to form a triangular support.
Further, the connecting member 2 may be directly rotatably coupled to the connecting socket 1, preferably by a bearing 12 to the connecting socket 1. The bearing 12 can be a thrust bearing, a race of the bearing 12 is fixedly connected with the connecting seat 1, and a shaft ring of the bearing 12 is fixedly connected with the connecting piece 2.
The above description has been made in detail only for the preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art, and all such changes are intended to be encompassed by the present invention.
