Description

Technical Field

[0001] This utility model relates to the field of inspection hammer technology, and in particular to a multifunctional inspection hammer. Background Technology

[0002] An inspection hammer, also known as a check hammer or inspection stick, is a tool typically used for inspections. Its design aims to help operators check for abnormal vibrations in railway tracks. When using it, the operator holds the end with their fingers and taps different parts of the railway with the hammer head. If there is looseness or abnormal vibration inside the railway, the vibration will be transmitted to the hand end, allowing the operator to judge the condition of the railway based on the vibration feedback.

[0003] In existing railway inspection work, inspection hammers are one of the commonly used tools for checking the mechanical condition of railway vehicles and identifying potential hazards. However, traditional railway inspection hammers can only perform basic mechanical inspection functions and lack specific means to inspect key sensor components. This not only limits the comprehensiveness and accuracy of inspection work but may also lead to the failure to detect safety hazards in a timely manner, increasing the risk of accidents.

A continuous Z-shaped measuring groove is formed on the side wall of the clamping plate along the length of the hammer handle. The continuous Z-shaped measuring groove is formed by connecting transverse and longitudinal surfaces arranged in a periodic alternation. The connection between adjacent transverse and longitudinal surfaces forms a first measuring part and a second measuring part with an included angle of 90°.

[0008] The longitudinal length of the first measuring part is greater than the longitudinal length of the second measuring part, forming an asymmetric Z-shaped groove structure;

[0009] When the card is in use, the height and horizontal position of the wheel sensor are measured by the asymmetric continuous Z-shaped measuring groove. The generated detection values ​​are compared with preset standard values ​​to determine the correctness of the sensor installation position.

[0010] Preferably, it also includes a round steel bar vertically set on the inspection hammer, with the central axes of the two being perpendicular to each other and having a diameter of 4 mm.

[0011] Preferably, the hammer handle is made of high-strength plastic material, with a total length of about 450mm, and the middle section is marked with a scale of 0mm-200mm.

[0012] Preferably, the hammer handle has a hollow structure, and a feeler gauge with a diameter of 1.0mm-1.5mm and a diameter of 1.5mm-2.0mm are installed inside the hollow structure. The end of the hammer handle is threaded with a spiral bottom cap.

[0013] By employing the above technical solution, this utility model provides a multifunctional inspection hammer, which has at least the following beneficial effects:

[0014] 1. This utility model, through the asymmetric continuous Z-shaped measuring groove design of the card plate, makes the wheel sensor measurement process more efficient and improves the overall detection accuracy and reliability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3 This embodiment proposes a multifunctional inspection hammer, including:

[0023] The inspection hammer 1 has a hammer handle 11 set perpendicularly to it, and the two central axes are perpendicular to each other. The bottom of the inspection hammer 1 maintains the style of a normal inspection hammer and is used for mechanical inspection, checking the condition of bolt fixing by tapping, etc.

[0024] The clamping plate 2 is fixed on the hammer handle 11 and is parallel to the central axis of the hammer handle 11. A continuous Z-shaped measuring groove 21 is opened on the side wall of the clamping plate 2 along the length direction of the hammer handle 11. The continuous Z-shaped measuring groove 21 is formed by connecting the periodically alternating transverse surfaces 211 and longitudinal surfaces 212. The connection between adjacent transverse surfaces 211 and longitudinal surfaces 212 forms a first measuring part 213 and a second measuring part 214 with an included angle of 90°.

[0025] The length of the longitudinal surface 212 of the first measuring part 213 is greater than the length of the longitudinal surface 212 of the second measuring part 214, forming an asymmetric Z-shaped groove structure;

[0026] When the card plate 2 is in use, the height and horizontal position of the wheel sensor are measured by the asymmetric continuous Z-shaped measuring groove 21. The generated detection values ​​are compared with the preset standard values ​​to determine the correctness of the sensor installation position.

[0027] Specifically, during use, the card plate 2 utilizes the asymmetric continuous Z-shaped measuring groove 21 to simultaneously perform multi-directional measurements of the wheel sensor. First, the first measuring section 213 within the asymmetric continuous Z-shaped measuring groove 21 measures the height of the wheel sensor. This precise measurement ensures that the sensor's vertical installation position meets requirements. Next, the second measuring section 214 measures the horizontal position of the wheel sensor, ensuring accurate horizontal positioning. Through the coordinated operation of these two measuring sections, the measurement data from the card plate 2, along with sensor installation-related detection values, are compared with preset standard values ​​to determine the accuracy of the sensor's installation position, ensuring normal sensor operation and system stability.

[0028] In another embodiment of this utility model, a round steel bar 3 is also included, which is vertically arranged on the inspection hammer 1, with the central axes of the two being perpendicular to each other and having a diameter of 4 mm.

[0029] Furthermore, one end of the inspection hammer 1 was replaced with a 4mm diameter round steel bar 3. This modification allows the inspection hammer 1 to function not only as a conventional inspection tool during maintenance but also as a 4mm non-locking test clamp for the switch machine. Switch machine testing is a crucial part of the maintenance process, ensuring the switch machine's operational performance and safety. In the non-locking test, the clamp is required to securely and precisely engage with relevant components of the switch machine to test its operation in the non-locking state. The 4mm diameter round steel bar 3 provides precisely the clamping capability needed to ensure the clamp's fixation and the reliability of the test during the process.

[0030] As another embodiment of this utility model, the hammer handle 11 is made of high-strength plastic material, with a total length of about 450 mm, and the middle section is marked with a scale of 0 mm-200 mm.

[0031] Furthermore, the hammer handle 11 is made of high-strength plastic or steel pipe, with a total length of approximately 450 mm, making it sturdy and durable. The middle section is marked with graduations from 0 mm to 200 mm, providing a convenient length reference during maintenance and measurement. Through this design, the hammer handle 11 not only serves as a common inspection tool but can also replace traditional steel rulers for precise measurement of turnout opening. Turnout opening is a critical parameter in railway facility maintenance, typically requiring precise tools to ensure accuracy. The hammer handle 11's clear graduations and suitable length allow for flexible application in turnout opening measurement, improving efficiency and accuracy during maintenance. This design further enhances the versatility of the hammer handle 11, providing convenience for railway equipment maintenance.

[0032] In another embodiment of this utility model, the hammer handle 11 is a hollow structure, and a feeler gauge with a diameter of 1.0mm-1.5mm and a diameter of 1.5mm-2.0mm are installed inside the hollow structure. The end of the hammer handle 11 is threadedly connected to a spiral bottom cover 4.

[0033] Furthermore, the hammer handle 11 features a hollow structure design, offering excellent portability and durability, making it suitable for extended use during maintenance. The hollow structure houses two feeler gauges of different sizes: one 1.0mm-1.5mm and one 1.5mm-2.0mm. This design allows for convenient and accurate measurement of gaps or crevices during the hammer handle 11's operation, especially in situations requiring detailed inspections based on different dimensions. The feeler gauges' mounting position also makes them easy to carry and use, eliminating the need to carry additional tools.

[0034] Furthermore, the hammer handle 11 is threadedly connected to a spiral cap 4 at its end. This design enhances the structural stability of the hammer handle 11 and also provides a secure storage space for the feeler gauge. When the feeler gauge is not in use, the spiral cap 4 can seal it, preventing loss or damage. At the same time, the threaded connection of the cap makes operation more convenient, allowing for easy disassembly or replacement, thereby improving the tool's lifespan and reliability.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
