Technical Field

[0001] This utility model belongs to the field of contact rail technology, specifically relating to a quick adjustment device for contact rail joints. Background Technology

[0002] As urban rail transit lines age, contact rails and related equipment gradually enter their overhaul period. Due to factors such as the equipment itself and its weight, the installation and adjustment of expansion joints and end elbows of contact rails often result in large gaps between the two contact rail joints after installation, making adjustment difficult. Currently, there are no specialized tools available for the installation and adjustment of contact rail joints. Therefore, to meet maintenance process requirements and improve work efficiency, it is necessary to propose a tooling solution suitable for adjusting contact rail joint gaps. Utility Model Content

[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] Example 1

[0036] See Figures 1-6 This embodiment discloses a quick adjustment device for a contact rail joint, including two clamping modules 1 for clamping the contact rail joint and an adjusting screw 3. Each clamping module 1 includes two jaws 101 and a connecting member 2; a locking structure 103 is provided between the two jaws 101, and when the locking structure 103 is in the locked state, the clamping module 1 is locked and fixed to the contact rail joint; the connecting member 2 is connected to one or both jaws 101, and the connecting member 2 has a threaded hole 201 that mates with the adjusting screw 3; the thread directions of the threaded holes 201 of the connecting members 2 on the two clamping modules 1 are opposite; the adjusting screw 3 has two threaded sections 302 with opposite directions, which respectively mate with the connecting members 2 of the two clamping modules 1.

[0037] Furthermore, the gripper 101 includes a connecting portion 1011 and a clamping portion 1012, with the clamping portion 1012 located below the connecting portion 1011; the connecting portion 1011 is arranged flat and cooperates with the locking structure 103; the inner side of the clamping portion 1012 matches the contour of the side of the contact rail.

[0038] In addition, for ease of carrying, each clamping module 1 also includes a handle plate 102, which is located between the two grippers 101, and the portion of the handle plate 102 above the two grippers 101 has a through groove. In the locked state, the locking structure 103 is connected to the two grippers 101 and the handle plate 102. Specifically, in this embodiment, the locking structure 103 uses bolts, with a threaded hole at the connection portion 1011 of the grippers 101, and a corresponding through hole on the handle plate 102. By locking the three together with the bolts, the two grippers 101 can be locked and fixed to the contact rail. In the unlocked state, the bolts do not completely lock the two grippers 101, but are threaded through the three together, making the two grippers 101 and the handle plate 102 form a whole, which is convenient for carrying and transferring.

[0039] Of course, the locking structure 103 in this embodiment can also adopt other detachable structures, such as bolt and nut structures, snap-fit ​​structures, etc., so as to facilitate locking the two jaws 101 onto the contact rail.

[0040] Furthermore, the handle plate 102 has an extension 1021 with two grippers 101 extending from one end facing the other clamping module 1. A card holder 104 is detachably connected to the extension 1021. The connector 2 is connected to the card holder 104. The extension 1021 has at least two first through holes extending along the width direction of the clamping module 1. The card holder 104 has a card groove 1043, and at least two second through holes 1044 are provided at the corresponding positions of the card holder 104 and the card groove 1043. The two second through holes 1044 communicate with the card groove 1043. In the assembled state, the extension 1021 is embedded in the card groove 1043, and a connecting pin passes through the first through hole and the second through hole 1044 to realize the assembly of the card holder 104 and the extension 1021.

[0041] In this embodiment, the connector 2 is in the shape of a long rod. One end of the connector 2 is the opening of a threaded hole 201, which extends axially. The other end of the connector 2 is the connecting end, used to connect with the card holder 104. The card holder 104 in this embodiment is provided with a connecting groove 1042. A limiting groove 1041 is provided on one side of the connecting groove 1042. The limiting groove 1041 communicates with the outside, and the width of the limiting groove 1041 is smaller than that of the connecting groove 1042. The connecting end of the connector 2 is provided with a locking block 203 and an anti-rotation block 202 in sequence. The locking block 203 corresponds to the connecting groove 1042, and the anti-rotation block 202 corresponds to the limiting groove 1041. The anti-rotation block 202 cooperates with the limiting groove 1041 to prevent the connector 2 from rotating.

[0042] Specifically, in this embodiment, the locking block 203 is circular and larger than the limiting groove 1041, which can prevent it from coming off during the gap adjustment process; while the anti-rotation block 202 has a hexagonal cross-sectional profile, which can prevent the connecting piece 2 from being driven when the adjusting screw 3 is rotated, ensuring that the gap adjustment purpose is achieved through the threaded engagement between the threaded hole 201 and the adjusting screw 3.

[0043] In this embodiment, the assembly of the card holder 104 and the handle plate 102 is achieved through structural cooperation and the use of connecting pins. The assembly of the card holder 104 and the connector 2 is even simpler; during use, the connecting end of the connector 2 is placed in the corresponding connecting groove 1042 and limiting groove 1041 of the card holder 104. In other words, the quick-adjustment device for the contact rail joint in this embodiment is very convenient to assemble and disassemble, and when not in use, multiple components can be disassembled for easy carrying.

[0044] In this embodiment, an adjustment section 301 is provided between the two threaded sections 302 on the adjusting screw 3. The cross-section of the adjustment section 301 is hexagonal. The hexagonal adjustment section 301 can be matched with the ratchet wrench 4, which facilitates turning the adjusting screw 3 and also makes it easier to control the accuracy of the gap adjustment.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
