Waterproof and dustproof integrated protection support for hydraulic ram sensor

Abstract

This application relates to an integrated waterproof and dustproof protective bracket for hydraulic rammer sensors, belonging to the technical field of sensor installation and protection for engineering machinery. It includes an L-shaped cavity, a sensor mounting assembly, a sealing and shock-absorbing assembly, and a protective assembly. The sensor mounting assembly includes a sensor mounting cavity fixedly connected to the inner wall of the L-shaped cavity. This application utilizes a locking rod, spring, sealing cover, sealing block, lead screw, and pressure plate. When the operator closes the sealing cover to the opening of the sensor mounting cavity, the locking rods on both sides are pushed by the springs into the locking holes on the sealing block, achieving rapid pre-locking. Subsequently, rotating the lead screw from the outside moves the pressure plate towards the sensor mounted on the mounting plate until the sensor is properly pressed. At this point, the pressure plate generates a counterforce on the sealing cover and sealing block, causing the sealing block to move slightly outward, which in turn presses the locking rods more tightly into the inner wall of the locking hole, effectively preventing the connection from easily loosening.

Description

Technical Field

[0001] This invention relates to the field of sensor installation and protection in engineering machinery, and in particular to an integrated waterproof and dustproof protective bracket for hydraulic rammer sensors. Background Technology

[0002] In the field of construction machinery, especially heavy compaction equipment such as hydraulic rammers, various sensors are widely installed to monitor equipment operating status, operational parameters, and achieve automated control. These sensors are crucial for ensuring construction quality, improving work efficiency, and ensuring equipment safety. With the increasing application of intelligent and digital technologies in construction machinery, the number and types of sensors are growing, placing higher demands on the stability and reliability of their working environment.

[0003] However, hydraulic rammers typically operate outdoors in harsh conditions characterized by dust, mud, and high vibration and impact. This poses a significant challenge to the sensors mounted on the machine and their connecting cables. Therefore, effectively protecting precision electronic components from environmental damage and ensuring their long-term stable and accurate signal acquisition and transmission has become a crucial concern and a pressing issue in the field. To address these challenges, an integrated waterproof and dustproof protective bracket for hydraulic rammer sensors has been proposed. Summary of the Invention

[0005] Technical problems to be solved

[0006] The purpose of this application is to provide an integrated waterproof and dustproof protective bracket for hydraulic rammer sensors to solve the problems mentioned in the background art.

[0007] The integrated waterproof and dustproof protective bracket for hydraulic rammer sensors provided in this application adopts the following technical solution: The integrated waterproof and dustproof protective bracket for hydraulic rammer sensors includes an L-shaped cavity, a sensor mounting assembly, a sealing and shock-absorbing assembly, and a protective assembly. The sensor mounting assembly includes a sensor mounting cavity fixedly connected to the inner wall of the L-shaped cavity. An mounting plate is installed on the inner wall of the sensor mounting cavity. A first shock-absorbing pad is fixedly connected to one side of the mounting plate. Locking rods are slidably connected to both sides of the outer surface of the sensor mounting cavity. A spring is sleeved on the outside of each locking rod. The two ends of the spring are fixedly connected to the outer surfaces of the sensor mounting cavity and the locking rod, respectively. The sealing and shock-absorbing assembly includes a sealing cover and a sealing block fixedly connected to the outer surface of the sealing cover. Locking holes are opened on both sides of the outer surface of the sealing block. Two locking rods are respectively inserted into the inner walls of the two locking holes. A lead screw is threadedly connected to the center of the sealing cover. The outer surface of the lead screw is threadedly connected to the inner wall of the sealing block. A pressure plate for positioning the sensor is fixedly connected to one end of the lead screw. The protective assembly seals both ends of the L-shaped cavity.

[0008] By adopting the above technical solution, the L-shaped cavity serves as the overall load-bearing skeleton, integrating the sensor mounting components, sealing and shock-absorbing components, and protective components at both ends into one unit. The corners of the L-shaped cavity naturally form clearance space, allowing for close placement against the rammer body and reducing the hassle of on-site hole modification or welding. Simultaneously, the insertion and engagement of the locking rod and the locking hole, combined with the preload of the spring, ensures that the sealing cover will not loosen on its own during equipment vibration. The lead screw drives the pressure plate from the outside to press the sensor, ensuring that the sensor does not shift under strong impact. Moreover, when the pressure plate presses the sensor, it generates a reverse force on the sealing cover and the sealing block, allowing the locking rod to be more stably inserted into the inner wall of the locking hole. After the protective components at both ends seal the L-shaped cavity, the internal sensor and cables are isolated from external mud, water, and dust, thereby improving the sensor's survival rate and signal stability in the harsh operating environment of the hydraulic rammer.

[0009] Preferably, a fixing base is fixedly connected to each of the four corners of the mounting plate, and the mounting plate is fixedly connected to the inner wall of the sensor mounting cavity by the fixing base and bolts, and the first shock-absorbing pad is located between the mounting plate and the sensor mounting cavity;

[0010] By adopting the above technical solution, the mounting plate is bolted to the sensor mounting cavity at four corners using the fixed bases at the four corners, resulting in uniform force distribution. The first shock-absorbing pad is pressed between the mounting plate and the bottom surface of the sensor mounting cavity, forming a complete elastic isolation layer. When the hydraulic rammer generates a strong impact, the vibration can be absorbed by the first shock-absorbing pad, and the energy transmitted to the sensor body is weakened, preventing the internal crystal oscillator or solder joints from failing due to long-term high-frequency vibration.

[0011] Preferably, the outer surface of the mounting plate is provided with mounting holes for positioning sensors, and each locking rod is fixedly connected to a paddle on its outer surface. The sealing cover is sealed at the opening of the sensor mounting cavity by a sealing block.

[0012] By adopting the above technical solution, the mounting hole can easily install and position the sensor on the outer surface of the mounting plate. The locking rods on both sides are pushed by the spring and inserted into the locking hole of the sealing block to achieve quick locking between the sealing cover and the sensor mounting cavity. On-site maintenance personnel can unlock it simply by turning the lever, which is more practical.

[0013] Preferably, a rubber pad is fixedly connected to one side of the pressure plate near the mounting plate, the pressure plate and the mounting plate are coaxially disposed inside the sensor mounting cavity, and a knob is fixedly connected to the other end of the lead screw, the knob being located outside the sensor mounting cavity;

[0014] By adopting the above technical solution, the knob is located outside the sensor mounting cavity. The operator can rotate the screw from the outside without opening the sealing cover. The screw drives the pressure plate to move axially, so that the rubber pad gently abuts against the outside of the sensor. This external adjustment method ensures that the sensor is reliably clamped, thereby reducing the impact of vibration on the sensor.

[0015] Preferably, a second waterproof gland is installed on the inner wall of the sensor mounting cavity, and a plurality of evenly distributed cable limiting buckles are installed on the inner wall of the L-shaped cavity.

[0016] By adopting the above technical solution, the second waterproof gland forms a waterproof and dustproof barrier at the outlet of the sensor lead cable. Even if external mud and water splash, they cannot flow back into the sensor installation cavity along the cable. The cable limiting buckle neatly fixes the extension cable to the inner wall of the L-shaped cavity. The two work together to solve the water ingress problem and extend the service life of the cable.

[0017] Preferably, an L-shaped observation window is embedded on the upper surface of the L-shaped cavity, and the L-shaped observation window is located above the multiple cable limiting buckles;

[0018] By adopting the above technical solution, the L-shaped observation window is made of transparent material embedded in the upper surface of the L-shaped cavity, corresponding to the distribution area of ​​the cable limiting buckle. In this way, when installing sensors and leads, the position of the cable can be observed more intuitively, which facilitates the positioning of the cable. Moreover, during daily inspections, the staff does not need to remove any cover plate and can directly check whether the internal cable is loose through the L-shaped observation window.

[0019] Preferably, the bottom surface of the L-shaped cavity is fixedly connected to multiple support columns, and the bottom surface of each support column is fixedly connected to a second shock-absorbing pad.

[0020] By adopting the above technical solution, the support column raises the entire protective bracket, leaving an airflow gap between the bottom surface of the L-shaped cavity and the hydraulic rammer body. The second shock-absorbing pad directly contacts the machine body, further filtering out vibrations from the equipment.

[0021] Preferably, the protective component includes a first sealing plate and a second sealing plate, which are respectively fixedly connected to the two ends of the L-shaped cavity by bolts. A sealing ring is embedded on the outer surface of the first sealing plate, and a sealing block is fixedly connected to the outer surface of the second sealing plate. Both the sealing ring and the sealing block are in sealing contact with the inner wall of the L-shaped cavity.

[0022] By adopting the above technical solution, the first sealing plate and the second sealing plate completely seal both ends of the L-shaped cavity, forming a relatively sealed internal space. The sealing ring and the sealing block respectively form an interference fit with the inner wall of the L-shaped cavity, which optimizes the actual waterproof effect of the L-shaped cavity.

[0023] Preferably, a first waterproof gland is installed on the inner wall of the first sealing plate, and protective eaves are fixedly connected to the outer sides of both ends of the L-shaped cavity. A sealing strip is fixedly connected to the inner wall of each protective eave, and the two sealing strips abut against the outer surfaces of the first sealing plate and the second sealing plate, respectively.

[0024] By adopting the above technical solution, the protective eaves extend outward from both ends of the L-shaped cavity, covering the joint and preventing rainwater from directly entering. The sealing strip is pressed between the protective eaves and the outer surfaces of the first and second sealing plates, forming a sealed defense line and optimizing the actual waterproof and dustproof effect.

[0025] Preferably, the outer surface of the L-shaped cavity is fixedly connected with uniformly distributed heat dissipation ribs;

[0026] By adopting the above technical solution, heat dissipation ribs are evenly distributed on the outer surface of the L-shaped cavity, increasing the heat exchange area between the L-shaped cavity and the outside air. The heat dissipation ribs can conduct and dissipate heat, preventing internal electronic components from being damaged due to overheating. At the same time, these heat dissipation ribs also act as reinforcing ribs, improving the impact resistance of the L-shaped cavity.

[0027] Beneficial effects

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] This invention provides an integrated waterproof and dustproof protective bracket for a hydraulic tamping sensor. By incorporating locking rods, springs, a sealing cap, a sealing block, a lead screw, and a pressure plate, when the operator places the sealing cap onto the opening of the sensor mounting cavity, the locking rods on both sides are pushed by the springs into the locking holes on the sealing block, achieving rapid pre-locking. Subsequently, rotating the lead screw from the outside moves the pressure plate toward the sensor mounted on the mounting plate until the sensor is properly pressed. At this point, the pressure plate generates a counterforce on the sealing cap and the sealing block, causing the sealing block to move slightly outward, which in turn presses the locking rods more tightly into the inner wall of the locking hole, effectively preventing the connection from easily loosening.

[0030] This invention provides an integrated waterproof and dustproof protective bracket for a hydraulic tamping sensor. By setting up a first sealing plate, a second sealing plate, a sealing ring, a sealing block, a first waterproof gland, a protective outer edge, and a sealing strip, the first and second sealing plates seal the L-shaped cavity from both ends. The sealing ring and sealing block form an interference fit with the inner wall of the cavity, blocking the path of mud and water seeping in from the end cap joint. Simultaneously, the protective outer edge extends outward from both ends of the cavity, covering the joint between the sealing plate and the cavity, preventing water from directly impacting the gap. The sealing strip is pressed tightly between the protective outer edge and the outer surface of the sealing plate, forming a seal. Furthermore, the first waterproof gland clamps and seals the cable passing through the first sealing plate, preventing water from being sucked back along the cable. Through these effects, a tiered protection function is achieved, optimizing the actual waterproofing effect.

[0031] This invention provides an integrated waterproof and dustproof protective bracket for a hydraulic tamping sensor. By incorporating a first shock-absorbing pad, a mounting plate, support columns, a second shock-absorbing pad, and heat dissipation ribs, the sensor is fixed to the mounting plate. The first shock-absorbing pad is pressed between the mounting plate and the bottom surface of the sensor mounting cavity, absorbing vibrations from the machine body. The entire device is elevated and installed using multiple support columns, each with a second shock-absorbing pad at its bottom to further isolate residual vibrations. Simultaneously, the heat dissipation ribs, evenly distributed on the outer surface of the L-shaped cavity, increase the contact area between the housing and the air, dissipating heat generated by the sensor itself and through thermal radiation from the machine body. In this way, the sensor is protected from strong vibrations and impacts, and avoids prolonged high-temperature operation, thus improving stability and service life. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0041] Example 1: Waterproof and dustproof integrated protective bracket for hydraulic rammer sensor, refer to Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The system includes an L-shaped cavity 1, a sensor mounting assembly 2, a sealing and shock-absorbing assembly 3, and a protective assembly 5. The sensor mounting assembly 2 includes a sensor mounting cavity 201 fixedly connected to the inner wall of the L-shaped cavity 1. A mounting plate 202 is installed on the inner wall of the sensor mounting cavity 201. A first shock-absorbing pad 203 is fixedly connected to one side of the mounting plate 202. Locking rods 206 are slidably connected to both sides of the outer surface of the sensor mounting cavity 201. A spring 207 is sleeved on the outside of each locking rod 206. The two ends of the spring 207 are respectively connected to the sensor mounting cavity 201 and the locking rod 206. The outer surface is fixedly connected, and the sealing and shock-absorbing assembly 3 includes a sealing cover 301 and a blocking block 302 fixedly connected to the outer surface of the sealing cover 301. Locking holes 303 are provided on both sides of the outer surface of the blocking block 302. Two locking rods 206 are respectively inserted into the inner walls of the two locking holes 303. A screw rod 304 is threadedly connected to the center of the sealing cover 301. The outer surface of the screw rod 304 is threadedly connected to the inner wall of the blocking block 302. One end of the screw rod 304 is fixedly connected to a pressure plate 305 for positioning sensors. The protective assembly 5 is respectively sealed at both ends of the L-shaped cavity 1.

[0042] Reference Figure 5 , Figure 6 and Figure 7The mounting plate 202 has fixed bases 204 at each of its four corners. The mounting plate 202 is fixedly connected to the inner wall of the sensor mounting cavity 201 via the fixed bases 204 and bolts. The first shock-absorbing pad 203 is located between the mounting plate 202 and the sensor mounting cavity 201. The mounting plate 202 is secured to the sensor mounting cavity 201 at four points with bolts via the fixed bases 204 at its four corners, ensuring even force distribution. The first shock-absorbing pad 203 is pressed between the mounting plate 202 and the bottom surface of the sensor mounting cavity 201, forming a complete elastic isolation layer. When the hydraulic rammer generates a strong impact, the vibration can be absorbed by the first shock-absorbing pad 203 and transmitted to the sensor body. The energy is weakened, preventing the internal crystal oscillator or solder joints from failing due to long-term high-frequency vibration. The outer surface of the mounting plate 202 is provided with mounting holes 205 for positioning the sensor. Each locking rod 206 has a fixedly connected paddle 208 on its outer surface. The sealing cover 301 is sealed at the opening of the sensor mounting cavity 201 by the sealing block 302. The mounting holes 205 can easily install and position the sensor on the outer surface of the mounting plate 202. The locking rods 206 on both sides are inserted into the locking holes 303 of the sealing block 302 under the push of the spring 207, realizing the quick locking of the sealing cover 301 and the sensor mounting cavity 201. On-site maintenance personnel only need to turn the paddle 208 to unlock, which is more practical.

[0043] Reference Figure 3 , Figure 4 and Figure 5 A rubber pad 306 is fixedly connected to the side of the pressure plate 305 near the mounting plate 202. The pressure plate 305 and the mounting plate 202 are coaxially arranged inside the sensor mounting cavity 201. A knob 307 is fixedly connected to the other end of the lead screw 304. The knob 307 is located outside the sensor mounting cavity 201. The operator can rotate the lead screw 304 from the outside without opening the sealing cover 301. The lead screw 304 drives the pressure plate 305 to move axially, so that the rubber pad 306 gently abuts against the outside of the sensor. This external adjustment method This ensures that the sensor is reliably clamped, thereby reducing the impact of vibration on the sensor. The inner wall of the sensor mounting cavity 201 is equipped with a second waterproof gland 6, and the inner wall of the L-shaped cavity 1 is equipped with multiple evenly distributed cable limiting clips 4. The second waterproof gland 6 forms a waterproof and dustproof barrier at the outlet of the sensor lead cable, so that even if external mud and water splash, they cannot flow back into the sensor mounting cavity 201 along the cable. The cable limiting clips 4 neatly fix the extension cable to the side of the inner wall of the L-shaped cavity 1. The two work together to solve the water ingress problem and extend the service life of the cable.

[0044] Example 2: Waterproof and dustproof integrated protective bracket for hydraulic rammer sensor, refer to Figure 1 , Figure 2 and Figure 3An L-shaped observation window 7 is embedded in the upper surface of the L-shaped cavity 1. The L-shaped observation window 7 is located above multiple cable limiting clips 4. The L-shaped observation window 7 is made of transparent material and embedded in the upper surface of the L-shaped cavity 1, corresponding to the distribution area of ​​the cable limiting clips 4. This allows for a more intuitive observation of the cable position during sensor and lead wire installation, facilitating cable positioning. Furthermore, during routine inspections, personnel do not need to remove any covers; they can directly check for loose internal cables through the L-shaped observation window 7. Multiple support pillars 8 are fixedly connected to the bottom surface of the L-shaped cavity 1, and each support pillar 8 has a fixedly connected bottom surface... The second shock-absorbing pad 9 and the support column 8 raise the entire device, leaving an airflow gap between the bottom surface of the L-shaped cavity 1 and the hydraulic rammer body. The second shock-absorbing pad 9 directly contacts the machine body, further filtering out vibrations from the equipment. The outer surface of the L-shaped cavity 1 is fixedly connected with evenly distributed heat dissipation ribs 10. The heat dissipation ribs 10 are evenly distributed on the outer surface of the L-shaped cavity 1, increasing the heat exchange area between the L-shaped cavity 1 and the outside air. The heat dissipation ribs 10 can conduct and dissipate heat, preventing damage to internal electronic components due to overheating. At the same time, these heat dissipation ribs 10 also act as reinforcing ribs, improving the impact resistance of the L-shaped cavity 1.

[0045] Reference Figure 1 , Figure 2 and Figure 3 The protective component 5 includes a first sealing plate 501 and a second sealing plate 502. The first sealing plate 501 and the second sealing plate 502 are respectively fixedly connected to both ends of the L-shaped cavity 1 by bolts. A sealing ring 503 is embedded on the outer surface of the first sealing plate 501, and a sealing block 504 is fixedly connected to the outer surface of the second sealing plate 502. Both the sealing ring 503 and the sealing block 504 are in sealing contact with the inner wall of the L-shaped cavity 1. The first sealing plate 501 and the second sealing plate 502 completely seal both ends of the L-shaped cavity 1, forming a relatively sealed internal space. The sealing ring 503 and the sealing block 504 respectively form an interference fit with the inner wall of the L-shaped cavity 1, optimizing the L-shaped cavity. The actual waterproof effect of cavity 1 is achieved by installing a first waterproof gland 505 on the inner wall of the first sealing plate 501, and fixing protective eaves 506 to the outer sides of both ends of the L-shaped cavity 1. A sealing strip 507 is fixedly connected to the inner wall of each protective eave 506. The two sealing strips 507 abut against the outer surfaces of the first sealing plate 501 and the second sealing plate 502, respectively. The protective eaves 506 extend outward from both ends of the L-shaped cavity 1, covering the joint and preventing rainwater from directly entering. The sealing strips 507 are pressed between the protective eaves 506 and the outer surfaces of the first sealing plate 501 and the second sealing plate 502, forming a sealed defense line and optimizing the actual waterproof and dustproof effect.

[0046] It should be noted that the first damping pad 203 and the second damping pad 9 can be made of rubber, polyurethane, or other elastic materials, as long as they can absorb vibration. The specific material is not limited. The sealing ring 503, sealing block 504, and sealing strip 507 can be made of materials with good weather resistance, such as EPDM rubber or silicone rubber, to ensure that they do not age or crack in the long-term outdoor environment. The L-shaped observation window 7 can be made of tempered glass or polycarbonate transparent plate. When it is installed, it can be fixed by sealant or slot to ensure that there is no gap between it and the upper surface of the L-shaped cavity 1. The distribution spacing and height of the heat dissipation ribs 10 can be adjusted according to the actual heat dissipation needs. The figures in this application are only schematic and do not limit the specific quantity and arrangement. The structures and materials not marked in detail in the figures can be understood and implemented by those skilled in the art based on the description in this application and conventional technical means, and will not affect the feasibility of the solution.

[0047] The implementation principle of this application embodiment is as follows: First, the L-shaped cavity 1 is fixed to the body of the hydraulic rammer by multiple support columns 8 at the bottom and the second shock-absorbing pad 9. The support columns 8 lift the L-shaped cavity 1 away from the surface of the body, leaving a gap for air circulation. The second shock-absorbing pad 9 directly contacts the body, filtering out part of the vibration generated by the equipment. When installing the sensor, the sensor body is first placed on the mounting plate 202, which has mounting holes 205. Then, the sensor is fixedly connected to the mounting plate 202 by bolts. The four corners of the mounting plate 202 are locked to the inner wall of the sensor mounting cavity 201 by fixing bases 204 and bolts. The first shock-absorbing pad 203 is pressed between the mounting plate 202 and the sensor mounting cavity 201, forming an elastic isolation layer. After the sensor is placed in position, the operator places the sealing cover 301 along with the sealing block 302 onto the opening of the sensor mounting cavity 201. During the closing process, the locking rods 206, which are slidably connected to both sides of the outer wall of the sensor mounting cavity 201, will be pushed by the spring 207 and inserted into the locking holes 303 on both sides of the sealing block 302. A click is heard, indicating that the quick pre-locking is completed. At this point, the sealing cover 301 has been initially fixed and will not pop open on its own. Next, the operator directly rotates the knob 307 located on the outside of the sensor mounting cavity 201 by hand. The knob 307 drives the lead screw 304 to rotate. The lead screw 304 passes through the central threaded hole of the sealing cover 301 and the sealing block 302, pushing the pressure plate 305 towards the sensor. The rubber pad 306 on the pressure plate 305 will gently... However, while firmly holding the top of the sensor in place, it's worth noting that when the pressure plate 305 presses the sensor, the sensor generates a reaction force on the pressure plate 305. This force is transmitted to the sealing cover 301 and the sealing block 302 through the lead screw 304, causing the sealing block 302 to have a slight tendency to move in the opposite direction. When the sealing block 302 moves slightly in the opposite direction, the inner wall of the locking hole 303 will press the locking rod 206 tightly. The lead cable on the sensor first passes through the second waterproof gland 6 on the inner wall of the sensor mounting cavity 201, forming a seal. Then, the cable runs along the inside of the L-shaped cavity 1 and is neatly fixed to the inner wall of the cavity by multiple evenly distributed cable limiting buckles 4 to prevent the cable from being damaged by back-and-forth friction during vibration. After the cable reaches the end of the cavity, it passes through the first sealing plate 501. The first waterproof gland 505 is then led out to connect to external equipment. The first sealing plate 501 and the second sealing plate 502 are respectively fixed to both ends of the L-shaped cavity 1 with bolts. The sealing ring 503 and the sealing block 504 form an interference fit with the inner wall of the L-shaped cavity 1 to seal the gaps at the ends. In addition, the protective eaves 506 on the outer sides of both ends of the L-shaped cavity 1 extend outward to cover the joints between the first sealing plate 501 and the second sealing plate 502 and the L-shaped cavity 1. The sealing strip 507 on the inner wall of the protective eaves 506 is pressed tightly against the outer surface of the first sealing plate 501 and the second sealing plate 502 to form a waterproof barrier. The L-shaped observation window 7 embedded on the upper surface of the L-shaped cavity 1 is made of transparent material, allowing direct observation of the internal cable arrangement during installation or maintenance.The heat dissipation ribs 10, evenly distributed on the outer surface of the cavity, not only increase the heat dissipation area but also act as reinforcing ribs, helping internal heat to dissipate in a timely manner and preventing the sensor from operating at high temperatures for extended periods.
