Description

Technical Field

[0001] This utility model relates to the technical field of railway track fastener fastening tools, and in particular to a T-shaped wrench for track fastener screws with torque measurement function. Background Technology

[0002] A T-shaped wrench with torque measurement function is a tool specifically designed for tightening and loosening track fastener screws. Its main function is to accurately apply appropriate torque to the track fastener screws through its unique design and torque measurement capabilities, ensuring a secure connection of the track fasteners and guaranteeing safe and stable track operation. Currently, in railway track maintenance, tightening fastener screws mainly relies on workers using a T-shaped wrench to apply torque to the fastener nut and judging the appropriateness of the torque by observing the gap between the spring clip's lower jaw and the fastener plate. However, due to differences in spring clip materials from different manufacturers, variations in operator arm strength, sense of responsibility, and the degree of rust on the spring clip, the gap observation method is difficult to meet the standard torque requirements stipulated by railway regulations.

[0003] Existing T-wrenches, when used, can cause excessive torque, which accelerates the fatigue and aging of the spring clips. This can also weaken the elasticity of the track structure, accelerate the wear of the rail surface and the aging of the rubber pads under the rails. Insufficient torque can make it difficult for the spring clip assembly to maintain the track gauge, leading to railway derailment accidents. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a T-wrench for track fastener screws with torque measurement function, aiming to improve the problem that the existing T-wrenches affect accuracy when the torque is too large or too small.

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.

[0023] Reference Figures 1-3 One embodiment of this utility model is a T-shaped wrench for track fastener screws with torque measurement function, including a torque meter 5. A second fixing post 14 is fixedly connected to the bottom of the torque meter 5. A lower hole sleeve 7 is provided at the bottom of the second fixing post 14. The bottom end of the second fixing post 14 passes through and extends into the lower hole sleeve 7. A long connecting rod 8 is fixedly connected to the bottom end of the lower hole sleeve 7. A working sleeve 9 is fixedly connected to the bottom end of the long connecting rod 8. A slot 12 is opened at the bottom end of the working sleeve 9. A disassembly component is provided at the top of the torque meter 5 for quick disassembly.

[0024] Specifically, the torque of the torque meter 5 is set by pressing button 11. During use, the current torque is determined by observing the display screen 10 on the torque meter 5. The torque value is displayed in real time during the tightening of the track fastener nut through the bottom working sleeve 9, and an alarm prompt is given when the target value is reached, which improves the accuracy of the uniformity between the torque of the fastener nut and the pressure of the spring clip.

[0025] Reference Figure 3 and Figure 4 The disassembly assembly includes a first fixing post 13, which is fixedly connected to a torque meter 5. The top of the first fixing post 13 is provided with an upper hole sleeve 3, and the left side of the first fixing post 13 is provided with a first transverse pin 4.

[0026] Specifically, by removing the first transverse pin 4, the top hole sleeve 3 can be removed, thereby replacing the top transverse handle 1 and the short connecting rod 2. The connecting rod can be replaced with a different length according to the actual needs of the worker, thus adapting to the needs of workers of different heights.

[0027] Reference Figure 3The top of the first fixing post 13 penetrates and extends into the interior of the upper hole sleeve 3, and the right end of the first transverse pin 4 penetrates and extends to the right side of the upper hole sleeve 3.

[0028] Specifically, the first fixed post 13 and the upper hole sleeve 3 are connected by the first transverse pin 4, and the torque is transmitted downward when the top transverse grip 1 is rotated.

[0029] Reference Figure 3 A second transverse pin 6 is provided on the left side of the second fixed post 14, and the right end of the second transverse pin 6 passes through and extends to the right side of the lower hole sleeve 7.

[0030] Specifically, the lower hole sleeve 7 and the second fixing post 14 are fixed by the second transverse pin 6, and the torque generated by the bottom working sleeve 9 is transmitted to the torque meter 5, thereby realizing real-time measurement of torque.

[0031] Reference Figure 1 A short connecting rod 2 is fixedly connected to the top end of the upper hole sleeve 3, and a horizontal handle 1 is fixedly connected to the top end of the short connecting rod 2.

[0032] Specifically, the horizontal handle 1 makes it easy for workers to hold the nut and apply force to tighten it.

[0033] Reference Figure 1 A display screen 10 is fixedly connected to the front of the torque meter 5, and four buttons 11 are provided on the front of the torque meter 5.

[0034] Specifically, the torque of the torque meter 5 can be set via button 11, and the torque data is displayed on the display screen 10, making it easy for workers to observe the real-time torque.

[0035] Reference Figure 3 The upper hole sleeve 3 and the first fixing post 13 are fixedly connected by the first transverse pin 4, and the lower hole sleeve 7 and the second fixing post 14 are fixedly connected by the second transverse pin 6.

[0036] Specifically, through-pins can fix them together and transmit a certain force and torque. Pin connections have the advantages of simple structure, convenient installation and disassembly, and reliable connection.

[0037] Reference Figure 2 The horizontal handle 1 is welded to the short connecting rod 2, the short connecting rod 2 is welded to the upper hole sleeve 3, the lower hole sleeve 7 is welded to the long connecting rod 8, and the long connecting rod 8 is welded to the working sleeve 9.

[0038] Specifically, welding can evenly distribute the force during operation between the components, reduce stress concentration, and create a continuous bond at the joint, providing high connection strength and rigidity.

[0039] Working principle: First, the torque of the torque meter 5 is set by button 11. Then, the user holds the horizontal handle 1 and applies force to make the working sleeve 9 fit onto the track fastener nut. During the tightening process, the torque generated by the bottom working sleeve 9 is transmitted to the second fixed column 14 through the second transverse pin 6, and then to the torque meter 5. The torque data is displayed on the display screen 10 in real time. When the set torque value is reached, the torque meter 5 gives an alarm prompt, and the user stops applying force.

[0040] If it is necessary to change the connecting rod to a different length according to the worker's height, the first transverse pin 4 can be removed, and the upper hole sleeve 3, together with the top transverse handle 1 and the short connecting rod 2, can be replaced. The welded connection ensures the uniform transmission of force between the components and the high connection strength, while the fixing pin ensures the disassembly between the components and the effective transmission of force.
