Description

Technical Field

[0001] This utility model relates to the field of railway maintenance tools, and in particular to a T-shaped wrench. Background Technology

[0002] A T-wrench, also called a T-type wrench or T-shaped wrench, is a common hand tool mainly used for tightening or loosening bolts and nuts. It is simple to make and allows for better application of torque. Larger T-wrenches are often used in railway construction and maintenance.

[0003] Traditional T-wrenches often use a vertical bar at one end to apply force, requiring rotation during use and making it inconvenient for workers to apply force. In railway maintenance work, one T-wrench requires two people to apply force simultaneously. When loosening or tightening railway bolts, two workers often need to rotate the wrench, which is time-consuming and labor-intensive, making it difficult to improve work efficiency in railway maintenance. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a ratchet-assisted T-wrench, which aims to improve the shortcomings of existing T-wrenches used in railway operations, optimize the force application structure, and improve the efficiency of railway screw inspection and maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ratchet-type torque T-wrench, comprising a T-wrench body, the T-wrench body including a handle, a connecting rod fixedly connected to the lower part of the handle, a ratchet wrench head fixedly connected to the lower part of the connecting rod, torque-enhancing connecting mechanisms provided on both the left and right sides of the handle, auxiliary grips fixedly connected to both the left and right sides of the top surface of the handle, a torque-enhancing rod provided in the middle of the torque-enhancing connecting mechanism, the torque-enhancing connecting mechanism including a sleeve, the torque-enhancing rod engaging with the sleeve, the sleeve fixedly connected to the handle, a fixing component provided in the middle of the sleeve, the fixing component including two clamping bars, the two clamping bars being symmetrically arranged, a fixing pad fixedly connected to the side of the two clamping bars that are far apart from each other, a guide block fixedly connected to the end of the two clamping bars near the handle, an adjusting rod threadedly connected through and threaded to the side of the two clamping bars near the handle, the adjusting rod being rotatably connected through and threaded to the sleeve.

[0006] As a further preferred embodiment of the above technical solution, the upper and lower parts of the adjusting rod are respectively provided with threads in opposite directions, and the middle part of the abutting bar is equipped with a threaded sleeve that matches the adjusting rod.

[0007] As a further preferred embodiment of the above technical solution, guide grooves are provided at both ends of the wrench handle, and the guide block is slidably connected to the guide groove.

[0008] As a further preferred embodiment of the above technical solution, the outer wall of the sleeve is fitted with a first anti-slip sleeve.

[0009] As a further preferred embodiment of the above technical solution, the surface of the first anti-slip sleeve is provided with a first anti-slip texture.

[0010] As a further preferred embodiment of the above technical solution, the outer wall of the auxiliary grip is fitted with a second anti-slip sleeve.

[0011] As a further preferred embodiment of the above technical solution, the outer wall of the second anti-slip sleeve is provided with a second anti-slip ridge.

[0012] As a further preferred embodiment of the above technical solution, the force-adding rod may be a hollow rod or a rod with a groove at one end that is compatible with the fixing component.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 and Figure 2 This utility model discloses a ratchet-type torque-enhancing T-wrench, comprising a T-wrench body 1, a large-volume wrench primarily used for railway construction and maintenance. The T-wrench body 1 includes a handle 11, which connects various components and facilitates the user's grip. A connecting rod 12 is fixedly connected to the lower part of the handle 11, perpendicular to the handle 11. A ratchet wrench head 13 is fixedly connected to the lower part of the connecting rod 12. This design allows workers to tighten or loosen bolts without needing to rotate the wrench. The ratchet and pawl engage to tighten or loosen the bolt. When tightening, the wrench rotates a certain angle, then rotates in the opposite direction to reset the torque-enhancing connection mechanism 2. If further tightening is needed, the wrench rotates another angle, repeating this process. This eliminates the need for workers to rotate, maintain a stable stance, and easily apply force.

[0025] like Figures 3 to 5 As shown, the outer wall of the sleeve 21 is fitted with a first anti-slip sleeve 22, which may be made of rubber. The surface of the first anti-slip sleeve 22 is provided with a first anti-slip ridge 221, which is circular and there are multiple ridges. The outer wall of the auxiliary grip 3 is fitted with a second anti-slip sleeve 31, which is made of rubber. The outer wall of the second anti-slip sleeve 31 is provided with a second anti-slip ridge 311, which is circular and there are multiple ridges. The force-adding rod 4 may be a hollow rod or a rod with a groove at one end that is compatible with the fixing component 23, so as to facilitate the connection with the force-adding connection mechanism 2 and facilitate storage and transportation.

[0026] Furthermore, the left and right sides of the wrench handle 11 are each equipped with a force-applying connecting mechanism 2, which is used to limit the movement of the force-applying rod 4. The top surface of the wrench handle 11 is fixedly connected to the left and right sides of the top surface of the wrench handle 11, which is used to assist the operator in gripping the handle. A force-applying rod 4 is provided in the middle of the force-applying connecting mechanism 2, which is used to increase torque. Its length can be selected according to actual needs. The force-applying connecting mechanism 2 includes a sleeve 21, which is fixedly connected to the wrench handle 11. The force-applying rod 4 is engaged with the sleeve 21. A fixing component 23 is provided in the middle of the sleeve 21, which is used to press and fix the inner wall of the force-applying rod 4, making it difficult for the force-applying rod 4 to detach from the sleeve 21. The fixing component 23 includes two clamping strips 231, which are symmetrically arranged, with the two clamping strips 231 on opposite sides. Each is fixedly connected with a fixing pad 232. Two clamping strips 231 are fixedly connected with guide blocks 233 near one end of the wrench handle 11. The guide blocks 233 can be T-shaped blocks. An adjusting rod 234 is threaded through and connected to one side of the two clamping strips 231 near the wrench handle 11. The adjusting rod 234 is used to adjust the distance between the two clamping strips 231, thereby facilitating the disassembly and assembly of the force lever 4. The upper and lower parts of the adjusting rod 234 are respectively provided with threads in opposite directions. A threaded sleeve adapted to the adjusting rod 234 is installed in the middle of the clamping strip 231. The adjusting rod 234 is rotatably connected to the sleeve 21. A torsion block is provided at the top of the adjusting rod 234 to facilitate the twisting by the operator. Guide grooves 111 are provided at the upper and lower parts of both ends of the wrench handle 11. The shape of the guides is adapted to the guide blocks 233. The guide blocks 233 are slidably connected to the guide grooves 111.

[0027] In use, firstly, select a suitable length of the lever 4 according to the actual usage. Then, insert one end of the lever 4 into one of the sleeves 21, so that the two clamping strips 231 can be inserted into the lever 4. Then, rotate the adjusting rod 234, which will control the two clamping strips 231 to move away from each other, so that the fixing pad 232 on the outer wall of the clamping strip 231 abuts against the inner wall of the lever 4, thereby fixing the lever 4 in the sleeve 21. Then, the ratchet wrench head at the lower part of the T-wrench body 1 is... The ratchet wrench head 13 is positioned on the outside of the railway bolt. One worker holds the end of the T-wrench handle 11 where the lever 4 is not fixed, while another worker holds the end of the lever 4 away from the T-wrench. This rotates the T-wrench body 1. During the application of force, the worker holding the handle 11 can also hold the auxiliary handle 3 for easier application. As the T-wrench body 1 rotates, the ratchet wrench head 13 loosens or tightens the bolt. The worker only needs to repeatedly turn the T-wrench to completely loosen or tighten the bolt. For bolt inspection along a railway section stretching ten or tens of kilometers, this method can significantly reduce work time.
