Description

Technical Field

[0001] The utility model relates to the technical field of rail lifting tools, and particularly relates to a special lifting tool for traveling crane rails. Background Art

[0002] At present, the existing original on-site lifting methods for rails are as follows: 1. The bundling method, which has little limitation, but the rail is prone to bending; 2. The lug plate method, which is prone to the mutual sliding of two lug plates, resulting in the falling of the rail. Content of the Utility Model

[0003] In view of the above technical problems, the utility model provides a special lifting tool for traveling crane rails.

[0004] In order to achieve the above object, the technical solution of the utility model is specifically as follows:

[0005] A special lifting tool for traveling crane rails, comprising:

[0006] An N-shaped connecting piece, the inner wall shape of which is adapted to the shape of the top of the rail;

[0007] Two second nuts, respectively arranged on the positioning holes on both sides of the N-shaped connecting piece;

[0008] Two bolts, respectively installed in cooperation with the two second nuts, and after the bolt heads enter the positioning holes, they press against the side wall of the rail, so that the N-shaped connecting piece and the rail are locked with each other;

[0009] A lug plate, which is provided with a connection hole at the top for connecting with a lifting device, and a notch at the bottom that can be adapted to the cross-sectional shape of the rail for sleeving on the rail;

[0010] Wherein, the lug plate is arranged at one end of the N-shaped connecting piece and is fixedly connected with the N-shaped connecting piece through a connecting component.

[0011] The connecting component includes:

[0012] A pin shaft, horizontally installed on two inserting plates on the side wall of the lug plate;

[0013] Two connecting plates, respectively arranged on both sides of the pin shaft, and one end of the connecting plate is connected with the bolt, and the other end is fixedly installed on the pin shaft through a first nut.

[0014] The beneficial effects of the present utility model are as follows: The present utility model is suitable for on-site hoisting, demolition, adjustment and other operation activities of steel rails, which can greatly improve work efficiency, save human resources, ensure safe maintenance and installation quality, and is suitable for hoisting of various steel rail models. The present utility model locks the n-shaped connecting piece and the steel rail to each other through two bolts, preventing sliding between the steel rail and the present utility model during the hoisting process. The inner wall shape of the n-shaped connecting piece is adapted to the shape of the top of the steel rail, enabling the n-shaped connecting piece to move on the steel rail, thereby realizing position adjustment to adapt to the hoisting of ultra-long steel rails. At the same time, a notch adapted to the cross-sectional shape of the steel rail is provided at the bottom of the lifting lug plate, enabling the lifting lug plate to also move on the steel rail to adapt to the position adjustment of the n-shaped connecting piece. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following further describes in detail the specific embodiments of the present utility model with reference to the drawings.

[0016] Figure 1 It is a structural schematic diagram of the present utility model.

[0017] Figure 2 is Figure 1 exploded view of. SPECIFIC EMBODIMENTS

[0018] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0019] As Figure 1 and Figure 2 shown, a special lifting tool for overhead traveling crane steel rails includes: an n-shaped connecting piece 7, the inner wall shape of which is adapted to the shape of the top of the steel rail 8; two second nuts 6, respectively arranged on the positioning holes on both sides of the n-shaped connecting piece 7; two bolts 5, respectively installed in cooperation with the two second nuts 6, and after the bolt heads enter the positioning holes, they press against the side wall of the steel rail 8, so that the n-shaped connecting piece 7 and the steel rail 8 are locked to each other; a lifting lug plate 4, with a connecting hole provided at the top for connecting with the lifting equipment, and a notch adapted to the cross-sectional shape of the steel rail 8 provided at the bottom for sleeving on the steel rail 8; wherein, the lifting lug plate 4 is arranged at one end of the n-shaped connecting piece 7 and is fixedly connected with the n-shaped connecting piece 7 through a connecting component.
