Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to railway construction and maintenance equipment field, concretely refers to a special lifting appliance for rail. BACKGROUND
[0002] In the railway construction and maintenance process, the hoisting operation of the rail is an indispensable link.
[0003] The traditional rail hoisting mode adopts a single lifting appliance to be directly connected through a rope or a chain to carry out the operation by the crane, and this mode needs the operator to continuously adjust to keep balance in the hoisting process, which is not only inefficient, but also has a great safety hazard.
[0004] Therefore, it is particularly important to develop a special lifting appliance for rail which can automatically keep balance and reduce manual intervention. SUMMARY
[0005] The utility model solves the technical problem of overcoming the above-mentioned technical defects, and provides a special lifting appliance for rail.
[0006] To solve the above technical problems, the technical scheme provided by the utility model is a special lifting appliance for rail, which comprises a lifting appliance, a lifting ring and a connecting bolt.
[0007] A lower clamping groove is formed in the lifting appliance body, and an opening part is formed in the bottom of the lifting appliance body.
[0008] Further, the lifting appliance body and the upper connecting part are integrally formed.
[0009] Further, the lower clamping groove and the opening part are communicated.
[0010] The utility model has the advantages compared with the prior art: the lifting appliance body and the upper connecting part are integrally formed, which enhances the structural strength and ensures the stability of the hoisting operation; at the same time, the detachable connecting structure of the lifting appliance and the lifting ring facilitates the assembly and maintenance of the lifting appliance, and reduces the use cost. BRIEF DESCRIPTION OF DRAWINGS
[0011] Figure 1 is the structural schematic diagram of the utility model;
[0012] Figure 2 is the structural schematic diagram of the lifting appliance of the utility model;
[0013] Figure 3 is the use reference drawing of the utility model.
[0014] As shown in the figure: 1, the lifting appliance, 101, the lifting appliance body, 102, the upper connecting part, 103, the connecting hole, 104, the lower clamping groove, 105, the opening part, 2, the lifting ring, 3, the connecting bolt. DETAILED DESCRIPTION
[0015] The utility model discloses a special lifting appliance for rail makes further detailed instructions below.
[0016] Combining with the drawing, a special lifting appliance for rail, including lifting appliance 1, lifting ring 2 and connecting bolt 3, lifting appliance 1 includes lifting appliance body 101 and upper connecting part 102, the top of lifting appliance body 101 is equipped with upper connecting part 102, upper connecting part 102 is set with connecting hole 103, the through hole corresponding to connecting hole 103 is set on lifting ring 2, connecting bolt 3 passes through the through hole, connecting hole 103 in proper order makes lifting appliance 1, lifting ring 2 constitutes detachable connecting structure;
[0017] Lifting appliance body 101 is set with lower clamping groove 104, and opening part 105 is set in the bottom of lifting appliance body 101.
[0018] As the preferred embodiment of the present embodiment, the lifting appliance body 101 and the upper connecting part 102 are integrally formed.
[0019] As the preferred embodiment of the present embodiment, the lower clamping groove 104 and the opening part 105 are in communication.
[0020] In the specific implementation of the utility model, the lower clamping groove 104 is set in the lifting appliance 101 for clamping the rail, and the opening part 105 is set in the bottom of the lifting appliance body 101, the lower clamping groove 104 and the opening part 105 are in communication, which facilitates the insertion and fixation of the rail, and the lifting appliance body 101 ensures that the rail can be smoothly clamped and stably clamped; the through hole corresponding to the connecting hole 103 is set in the lifting ring 2 for connection with the lifting appliance 1, the lifting ring 2 and the lifting appliance 1 are fixedly connected by passing through the through hole of the lifting ring 2 and the connecting hole 103 of the lifting appliance 1 to form a detachable connecting structure, which facilitates assembly and maintenance.
[0021] When hoisting the rail, the device is used in pairs, two lifting appliances 1 are symmetrically clamped on both sides of the rail respectively to provide two hoisting points for the rail, which can ensure the balance of the rail during hoisting and avoid the manual balance adjustment operation in the traditional single-lifting appliance mode, thereby reducing the operation risk and improving the efficiency.
[0022] The above has described the utility model and its implementation mode, which is not restrictive, and the drawings only show one of the implementation modes of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
