Description

Technical Field

[0001] The utility model relates to the technical field of installation tools, in particular to a multifunctional positioning and installation wrench. Background Art

[0002] In order to ensure the stability and reliability of the operation of the contact network system, the installation of the contact network suspension string in China needs to meet certain process standards. The installation process requires that the angle of the suspension string current ring be inclined at an angle at the contact line end and inclined at an angle at the load-bearing cable end. Both angles are standardized by industry standards. However, when installing the suspension string, workers mainly use two wrenches to clamp the nuts and bolts at the front and rear ends of the bolts to tighten them. In addition, during the installation process, there are no corresponding tools to limit the relative positions of the nuts, bolts and the wire noses of the suspension string current rings. When the nut is rotated to a tightening torque close to the bolt, the bolt will rotate with the nut, causing the wire nose of the suspension string current ring to move together, making it difficult to control the process standards during the installation of the suspension string, and the work efficiency is very low.

The utility model has a simple structure. When in use, it is only necessary to clamp the bolt head in the clamping groove between the two main bolt clamping blocks and clamp the hanging string wire clamp in the vertical positioning groove, so that the handle can be positioned on the hanging string as a whole, and the bolt rotation is prevented from causing the handle to swing left and right when the nut at the rear end of the bolt is tightened. Moreover, since the clamping groove is a through groove, the bolt head can be slightly moved within the length of the clamping groove, and the distance requirement between the vertical positioning groove and the clamping groove does not need to be very precise. Therefore, it is very convenient to manufacture and use, and can make the installation of the hanging string simple and quick, thereby greatly improving the work efficiency.

[0023] In this embodiment, both ends of the working surfaces of the two main bolt blocks 2 along the length direction are inclined toward the outside of the handle, so that the openings at both ends of the slot 21 are trumpet-shaped, which is convenient for guiding the bolt head when it is clamped in the slot.

[0024] In this embodiment, a first vertical limit baffle 7 is further provided on the upper surface of the handle 1 on one side close to the second angle positioning groove 6. The distance between the first vertical limit baffle 7 and the center line of the handle 1 is such that when the clamping groove 21 clamps the head of the string clamp bolt, the first vertical limit baffle 7 can contact the side of the string clamp. A second vertical limit baffle 8 is further provided on the side of the handle 1 away from the first angle positioning groove 5. The second vertical limit baffle 8 is located between the main bolt clamp 2 and the vertical positioning groove 4, and its height is greater than that of the first vertical limit baffle 7.

[0025] In this embodiment, the vertical positioning groove 4 includes a rectangular positioning plate perpendicular to the upper surface of the handle 1, and a U-shaped groove for clamping the string clamp is opened in the middle of the top of the rectangular positioning plate.

[0026] In this embodiment, the first angle positioning groove 5 and the second angle positioning groove 6 both include a base plate and baffles located on both sides of the base plate, one end of the base plate is connected to the side of the handle 1, and the other end is inclined at an angle toward the lower surface of the handle 1, and the baffles are located on both sides of the other end of the base plate, and the spacing between the two baffles matches the diameter of the suspension string; the two base plates are located in the same plane and arranged side by side in an "eight" shape, and the center lines of the two are set with the same angle but in opposite directions with the center line of the handle, and the angle matches the angle between the suspension string current-carrying ring and the contact line or the load-bearing cable.

[0027] In this embodiment, a crimping tube push rod groove 9 is provided in the middle position of the other end of the handle 1, and the extension direction of the crimping tube push rod groove 9 is consistent with the length direction of the handle, that is, the center line of the crimping tube push rod groove 9 is consistent with the center line of the handle 1.

[0028] In this embodiment, a spare plum blossom through hole 3 is further provided at the other end of the handle 1 , which is located between the crimping tube push rod groove 9 and the main bolt clamping block 2 .

[0029] The use of the utility model:

[0030] When installing the suspension string clamp at the contact line end, the wire nose of the suspension string current ring is sleeved on the bolt, and then the bolt is installed on the suspension string clamp, and the nut is screwed on the tail end of the bolt, and then the clamping groove 21 between the main bolt clamping block 2 in the utility model is clamped on the bolt head of the suspension string clamp, and the suspension string clamp is clamped in the vertical positioning groove 4, and the wire clamp at the wire nose end of the suspension string current ring is clamped in the first angle positioning groove 5, at this time, the vertical limit baffle 7 is just placed on the side of the suspension string clamp, and finally the nut at the tail end of the bolt is tightened with another wrench. Since the vertical positioning groove 4 and the clamping groove 21 position the handle 1 as a whole on the suspension string, it can prevent the bolt from rotating when the nut is tightened by another wrench, and the first angle positioning groove 5 positions the wire nose end of the suspension string current ring at an angle specified with the suspension string, preventing the wire nose from rotating with the bolt, so that during the installation process, the operator only needs to use another wrench to rotate the nut, which is simple in structure and convenient to use, making the installation of the suspension string simple and improving work efficiency. The second angle positioning groove 6 is used for installing the suspension string clamp at the end of the load-bearing cable, so as to locate the angle between the suspension string current-carrying ring and the load-bearing cable end.

[0031] The above description is only the preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
