Description

Technical Field

[0001] This utility model relates to the field of hydraulic sensor technology, specifically to a hydraulic sensor for industrial vehicles. Background Technology

[0002] Industrial vehicles, as core equipment in logistics warehousing, mining, and engineering construction, directly impact the smoothness of the industrial production chain and economic benefits through their operational efficiency, safety, and reliability. Hydraulic systems, with their advantages of high power density, smooth transmission, and high control precision, have become the core power transmission and execution unit for various industrial vehicles such as forklifts, loaders, cranes, and mining dump trucks. They undertake key functions such as lifting, steering, braking, and driving working devices, and their operating status directly determines the operational performance and safety of industrial vehicles.

[0003] With the development of industrial automation and intelligent manufacturing technologies, industrial vehicles are upgrading towards larger size, higher intelligence, and higher efficiency, placing more stringent demands on the performance of hydraulic sensors. Currently, existing hydraulic sensors still face many unresolved issues in industrial vehicle applications. For example, a Chinese patent application with publication number CN203069310U discloses a hydraulic sensor comprising a base, an O-ring, a retaining ring, a ceramic seat, a copper ring, a flexible circuit board, and a plastic connector. The retaining ring and ceramic seat are both housed within the base. A spring is positioned between the ceramic seat and the copper ring, with one end connected to the ceramic seat and the other end connected to the copper ring. This technical solution achieves product sealing. Furthermore, when the measured medium changes from liquid to solid, the pressure felt by the product increases instantaneously by 10 to 30 times. At this time, the spring undergoes compression deformation, increasing its volume and reducing the internal pressure, thus providing protection. When the measured medium changes from solid to liquid, the spring returns to its original encasing shape, thus not affecting the product's sealing performance.

[0004] However, in actual use, because existing hydraulic sensors use snap-fit ​​or plug-in connections to adapt to specific hydraulic valve group interfaces, the maintenance of these hydraulic sensors is complicated by calibration and replacement, which prolongs downtime. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic sensor for industrial vehicles, which connects the disassembly interface to the hydraulic sensor body through quick-release bolts, thus solving the technical problem of high complexity in connecting the disassembly interface and the hydraulic valve interface in traditional snap-fit ​​structures, resulting in excessive downtime during maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A hydraulic sensor for industrial vehicles includes a hydraulic sensor body, which includes a mechanism body. The hydraulic valve connection end of the mechanism body is fixedly connected to a connection port, and a disassembly interface is provided at the bottom of the connection port for easy removal of the hydraulic sensor body. The disassembly interface includes an interface body, which is fixedly connected to the connection port by quick-release bolts. The bottom of the interface body is provided with a hydraulic valve interface, which is used to install the hydraulic sensor body into the hydraulic valve interface.

[0007] Preferably, an extension plate is fixedly connected to the outer wall of the connection port, a plurality of limiting posts are fixedly connected to the bottom of the extension plate, and a first wedge block is fixedly connected to the bottom of the limiting posts.

[0008] Preferably, a fixing plate is fixedly connected to the outer wall of the interface body, and the outer wall of the fixing plate has multiple fixing holes, with limit posts provided inside the fixing holes.

[0009] Preferably, a mounting plate is fixedly connected to the bottom of the interface body, and multiple limiting grooves are provided on the top corners of the mounting plate.

[0010] Preferably, the hydraulic valve interface includes a valve interface body, the top of which is mounted to the bottom of the interface body, and a mounting groove is fixedly connected to the bottom of the valve interface body, with the mounting plate inserted into the mounting groove.

[0011] Preferably, the surface of the mounting groove is provided with multiple extension grooves, and a hydraulic telescopic rod is fixedly connected to the inner wall of the extension groove. A second wedge block is fixedly connected to one end of the surface of the hydraulic telescopic rod, and the second wedge block matches the inclined side of the first wedge block.

[0012] Preferably, a buffer spring is sleeved on the surface of the hydraulic telescopic rod, and the two ends of the buffer spring are fixedly connected to the inner wall of the extension groove and the outer wall of the second wedge block, respectively.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model discloses a hydraulic sensor for industrial vehicles, which achieves a detachable connection between the disassembly interface and the hydraulic sensor body through quick-release bolts. When the hydraulic sensor needs maintenance, only the quick-release bolts need to be removed to take out the hydraulic sensor body for maintenance. The disassembly interface is always fixedly installed on the surface of the hydraulic valve interface. This solves the technical problem of high complexity in the connection between the disassembly interface and the hydraulic valve interface in the traditional snap-fit ​​structure, which leads to excessive downtime during maintenance. This significantly improves the efficiency of equipment maintenance. 2. In the hydraulic sensor for industrial vehicles of this utility model, during the insertion of the hydraulic sensor body into the disassembly interface, the limiting post on its surface is simultaneously embedded into the extension groove of the hydraulic valve interface. The first wedge block drives the second wedge block to retract, thereby realizing the synchronous completion of the insertion of the hydraulic sensor body into the disassembly interface and its fixation to the hydraulic valve interface. This significantly improves the structural stability of the hydraulic sensor body connection. When the hydraulic sensor body is removed, the buffer spring will rebound, and at this time, the second wedge block will fix the mounting plate into the mounting groove, ensuring that the disassembly interface and the hydraulic valve interface maintain reliable installation stability after the hydraulic sensor body is removed, and preventing the interface from loosening or detaching.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-5The hydraulic sensor for industrial vehicles shown includes a hydraulic sensor body 1, which includes a mechanism body 11. The hydraulic valve connection end of the mechanism body 11 is fixedly connected to a connection port 12. The bottom of the connection port 12 is provided with a disassembly interface 2 for easy removal of the hydraulic sensor body 1. The disassembly interface 2 includes an interface body 21, which is fixedly connected to the connection port 12 by quick-release bolts.

[0019] Therefore, when the hydraulic sensor needs maintenance, only the quick-release bolts need to be removed to take out the hydraulic sensor body 1 for inspection and maintenance, while the disassembly interface 2 is always fixedly installed on the surface of the hydraulic valve interface 3 for easy use.

[0020] The bottom of the interface body 21 is provided with a hydraulic valve interface 3, which is used to install the hydraulic sensor body 1 into the hydraulic valve interface 3.

[0021] To achieve rapid positioning of the hydraulic sensor body 1 onto the surface of the disassembly interface 2, such as Figure 2-3 As shown, an extension plate 13 is fixedly connected to the outer wall of the connection port 12, and multiple limiting posts 14 are fixedly connected to the bottom of the extension plate 13. A fixing plate 22 is fixedly connected to the outer wall of the interface body 21. Multiple fixing ports 23 are opened on the outer wall of the fixing plate 22, and the limiting posts 14 are provided inside the fixing ports 23.

[0022] Before the hydraulic sensor body 1 moves to the surface of the disassembly interface 2, multiple limiting posts 14 need to be aligned with the fixing port 23 in sequence. After alignment, the hydraulic sensor body 1 is slowly moved to the surface of the disassembly interface 2. Through the above structure, the hydraulic sensor body 1 can be positioned and then fixed during the installation process, which makes it easier to install the hydraulic sensor body 1 onto the surface of the disassembly interface 2.

[0023] The bottom of the interface body 21 is fixedly connected to a mounting plate 24, and multiple limiting grooves 25 are provided on the top corners of the mounting plate 24.

[0024] The hydraulic valve interface 3 includes a valve interface body 31. The top of the valve interface body 31 is installed on the bottom of the interface body 21. It should be noted that during vehicle production, the interface body 21 needs to be installed on the appropriate surface of the valve interface body 31. During the connection between the interface body 21 and the valve interface body 31, the connection is achieved through a snap-fit ​​structure. The snap-fit ​​structure is located on the surface of the connection point between the interface body 21 and the valve interface body 31. The snap-fit ​​structure is a mature existing technology, and its internal structure and working principle will not be described in detail here.

[0025] Based on the snap-fit ​​structure, in order to limit the disassembly interface 2 to the surface of the hydraulic valve interface 3, such as Figure 4-5As shown, the bottom of the valve interface body 31 is fixedly connected to the mounting groove 32, and the mounting plate 24 is inserted into the mounting groove 32.

[0026] Multiple extension slots 33 are formed on the surface of the mounting slot 32. A hydraulic telescopic rod 35 is fixedly connected to the inner wall of the extension slot 33. A second wedge block 34 is fixedly connected to one end of the surface of the hydraulic telescopic rod 35. A first wedge block 15 is fixedly connected to the bottom of the limiting post 14. The second wedge block 34 matches the inclined side of the first wedge block 15. During the downward insertion of the hydraulic sensor body 1, the first wedge block 15 will be inserted into the limiting slot 25. At this time, the second wedge block 34 is set in the limiting slot 25. During the continued downward insertion of the hydraulic sensor body 1, the inclined surface of the first wedge block 15 will contact the inclined surface of the second wedge block 34. At this time, a force in a certain direction will be applied to the second wedge block 34, causing it to move outward. The outward movement of the second wedge block 34 will drive the hydraulic telescopic rod 35 to extend and retract, and finally realize that the first wedge block 15 is inserted into the limiting slot 25. This realizes the synchronous completion of the insertion of the hydraulic sensor body 1 into the disassembly interface 2 and the fixing to the hydraulic valve interface 3, which greatly improves the structural stability of the connection of the hydraulic sensor body 1.

[0027] When the hydraulic sensor body 1 needs to be repaired and removed, a buffer spring 36 is sleeved on the surface of the hydraulic telescopic rod 35. The two ends of the buffer spring 36 are fixedly connected to the inner wall of the extension groove 33 and the outer wall of the second wedge block 34, respectively. At this time, the elastic force of the buffer spring 36 can make it rebound, thereby causing the second wedge block 34 to rebound back into the limiting groove 25. This ensures that after the hydraulic sensor body 1 is removed, the disassembly interface 2 and the hydraulic valve interface 3 still maintain reliable installation stability, avoiding loosening or detachment of the interface.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
