Description

Technical Field

[0001] The utility model relates to the technical field of supporting tools, in particular to a convenient opening device for a rigid contact network busbar. Background Art

[0002] In recent years, urban rail transit is gradually expanding to major cities, and overhead rigid contact networks are widely used in rail transit projects;

[0003] At present, a wire-laying trolley is used to handle the de-grooving and cleaning of clamped foreign objects in the rigid contact network. However, the wire-laying trolley is heavy, with an overall weight of about 2.3KG. It is troublesome to install and requires two operators to install it simultaneously. It also requires high skills and proficiency of the operators. Improper installation will damage the bus, resulting in a decrease in clamping force, which further increases the frequency of faults. In addition, when a fault occurs, the wire-laying trolley needs to be moved back and forth, which requires a certain amount of strength from the operators. The entire handling process will greatly affect the progress of the entire operation.

[0004] To this end, a convenient opening device for a rigid contact network busbar is proposed to solve the above-mentioned problems. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] Example:

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A convenient opening device for a rigid contact network busbar comprises two support blocks 1, which are symmetrically arranged. A groove is provided on the adjacent side of the two support blocks 1, and a limiting slide rail 2 is fixedly arranged inside the two grooves. A threaded rod 3 is threaded on the upper side walls of the two support blocks 1, and a clamping plate 4 is rotatably arranged on the lower end of the threaded rod 3. A limiting slide groove is provided on the side away from the two clamping plates 4, and the limiting slide groove is slidably connected to the limiting slide rail 2. A clamping port is provided on the lower side wall of the clamping plate 4. A threaded mounting rod 5 is fixedly arranged on the lower side walls of the two support blocks 1, and a supporting tube 6 is provided on the external thread of the threaded mounting rod 5. In the past, it took at least 40 minutes to deal with the fault of the contact line of the rigid contact network busbar being out of the groove and cleaning the clamped foreign objects. The device in the present application can shorten the time to less than 10 minutes. It has the advantages of light weight, simple installation, low skill requirements for personnel, and convenient carrying.

[0025] A busbar 7 is arranged between the two support blocks 1 , and the two bayonet holes are matched with the upper surface of the busbar 7 .

[0026] Symmetrical rotating handle insertion holes 8 are provided at the upper ends of the rod walls of the two threaded rods 3. When the threaded rods 3 need to be rotated, it is difficult to rotate them directly by hand. The rotating handles can be inserted into the rotating handle insertion holes 8 to easily rotate the threaded rods 3, which is more labor-saving.

[0027] The lower ends of the two support blocks 1 on the adjacent side are provided with steps, and the two ends of the bus 7 are clamped with the steps. The bus 7 can be firmly supported and limited by the two support blocks 1, thereby increasing the support stability.

[0028] The two support blocks 1 are 100 mm long, 60 mm wide and 130 mm high; the support tube 6 is 1000 mm high, with an inner diameter of 25 mm and a wall thickness of 2 mm.

[0029] The support block 1 and the limiting slide rail 2 are integrally formed of aluminum alloy, thereby avoiding the possibility of deformation due to excessive force.

[0030] Working principle:

[0031] When using the device, the operator loosens the two threaded rods 3, clamps the device in the corresponding position, and tightens the threaded rods 3, thereby driving the two clamping plates 4 to move downward to clamp the bus 7. During operation, two support tubes 6 are installed, and the operator slowly applies external force to clamp the contact wire into the clamping mouth at the same time. When the contact wire is completely embedded in the bus, the external force is withdrawn, and the removal process is completed when it is observed that there is no problem with the contact wire.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description. Therefore, it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model, and any figure marks in the claims should not be regarded as limiting the claims involved.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
