Description

Technical Field

[0001] This utility model relates to the field of railway engineering technology, and in particular to a track gauge adjustment device for subway maintenance. Background Technology

[0002] Track gauge adjustment is a crucial task in the construction and maintenance of subway systems. Track gauge refers to the distance between two parallel tracks, and it is essential for ensuring the safe and smooth operation of trains. Deviations in track gauge can not only affect train performance but also increase wear and tear, and even lead to safety accidents. Therefore, track gauge adjustment devices are frequently used during subway track maintenance to precisely adjust the distance between the tracks.

[0003] Currently, the gauge blocks used in subway tracks are all made of plastic. When maintaining and adjusting the gauge blocks, the gauge blocks are prone to breakage during installation, or when using a pry bar to adjust the gap between the gauge blocks and the rails, the pry bar may slip and cause injury. Overall, the operation may result in material waste and the risk of personnel injury. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing track gauge adjustment devices suffer from safety risks and efficiency issues during use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a track gauge adjustment device for subway maintenance, including a long support pad and a rerouting threaded rod. A threaded sleeve is fixedly connected to the bottom of the long support pad and is threadedly connected to the outside of the rerouting threaded rod. Two nuts are threadedly connected to the outside of the rerouting threaded rod. An adjusting block is rotatably connected to one end of the rerouting threaded rod. Stable clamping mechanisms are provided at the bottom of both ends of the long support pad.

[0006] As a further improvement of this utility model, the two nuts are located on both sides of the threaded sleeve.

[0007] As a further improvement of this utility model, the rerouting threaded rod is rotatably connected to the adjusting block through the first bearing, and the end of the rerouting threaded rod away from the adjusting block is provided with an internal hexagonal groove.

[0008] As a further improvement of this utility model, the stable clamping mechanism includes a fixing block disposed at the bottom of the long support pad and fixedly connected thereto. A screw threadedly connected to the fixing block is threaded through it. A knob is fixedly connected to one end of the screw, and a clamping plate is rotatably connected to the other end of the screw.

[0009] As a further improvement of this utility model, the screw is rotatably connected to the clamping plate via a second bearing.

[0010] The beneficial effects of this utility model are as follows: By using an improved track gauge adjustment device, this utility model eliminates the risk of accidental injury caused by the slippage of the pry bar during the traditional track gauge block adjustment process, ensuring the personal safety of maintenance personnel; in addition, the design of the stable clamping mechanism can better fix the track gauge adjustment device, reducing the safety hazards caused by the movement of the track gauge adjustment device.

[0018] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0019] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0020] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] This utility model provides the following: Figure 1-6 The illustrated track gauge adjustment device for subway maintenance includes a long support plate 1 and a rerouting threaded rod 2. A threaded sleeve 3 is fixedly connected to the bottom of the long support plate 1 and is threadedly connected to the outside of the rerouting threaded rod 2. Two nuts 4 are threadedly connected to the outside of the rerouting threaded rod 2 and are respectively located on both sides of the threaded sleeve 3. An adjusting block 5 is rotatably connected to one end of the rerouting threaded rod 2. Stable clamping mechanisms 6 are provided at the bottom of both ends of the long support plate 1. The rerouting threaded rod 2 is rotatably connected to the adjusting block 5 through a first bearing 7, which improves the stability of the rerouting threaded rod 2 when rotating. An internal hexagonal groove 8 is provided at the end of the rerouting threaded rod 2 away from the adjusting block.

[0022] like Figure 3 As shown, the stable clamping mechanism 6 of this utility model includes a fixing block 601 fixedly connected to the bottom of the long support plate 1. A screw 602 threadedly connected to the fixing block 601 is threaded through it. A knob 603 is fixedly connected to one end of the screw 602, and a clamping plate 604 is rotatably connected to the other end of the screw 602. The screw 602 is rotatably connected to the clamping plate 604 through a second bearing 605. Through the design of the stable clamping mechanism, it can be ensured that the clamping plate 604 can firmly clamp the track base pillow 9 during the track gauge adjustment process, thereby avoiding safety hazards caused by the movement of the device.

[0023] Working principle: In specific implementation, this utility model firstly... Figure 5 or Figure 6The device is installed on the track base pillow 9 and the track body 10 in the shown state. At this time, the long support pad 1 is located on the two track base pillows 9, and the adjusting block 5 is locked in place by the track body 10. By rotating the control knob 603, the screw 602 is driven to rotate. Since the screw 602 is threadedly connected to the fixing block 601 and is rotatably connected to the clamping plate 604 through the second bearing 605, when the screw 602 rotates, it will slide to one side, thereby driving the clamping plate 604 to move. This allows the clamping plate 604 to firmly clamp the track base pillow 9, thus avoiding safety hazards caused by the movement of the device.

[0024] The nut 4 is moved by the adjustable wrench and the two nuts 4 are pressed tightly against the long support plate 1. Then the adjustable wrench is used to fix the nut 4. The hex wrench is used to cooperate with the internal hexagonal groove 8 at one end of the diversion threaded rod 2 to realize the rotation of the diversion threaded rod. When the diversion threaded rod 2 rotates, since the threaded sleeve 3 is fixed on the long support plate 1, the diversion threaded rod 2 will move along the axis of the threaded sleeve 3. At this time, the movement of the diversion threaded rod 2 will drive the adjusting block 5 to move relative to the track body 10, thereby realizing the adjustment of the track gauge between the track bodies 10.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
