Description
Technical Field
[0001] This utility model relates to the technical field of dustproof and temperature-controlled devices, specifically a crane positioning vehicle-mounted dustproof and temperature-controlled device. Background Technology
[0002] A bridge crane, also known as an overhead crane, is a type of crane whose bridge structure runs on elevated tracks. The bridge of the bridge crane runs longitudinally along tracks laid on both sides of the elevated structure, while the trolley runs laterally along tracks laid on the bridge, forming a rectangular working area. This allows for full utilization of the space beneath the bridge for lifting and transporting materials without obstruction from ground equipment. These cranes are widely used in indoor and outdoor warehouses, factories, docks, and open-air storage yards. To ensure real-time positioning of the bridge, a vehicle-mounted GPS device is typically installed on the bridge for location tracking.
[0003] Existing overhead crane GPS navigators experience significant vibrations during crane operation, leading to data transmission and reception malfunctions or data loss. Furthermore, the vibrations can loosen the connection between the navigator and the crane body, potentially causing it to detach and damage the device. Moreover, prolonged use results in the accumulation of dust, hindering heat dissipation and overall functionality. Therefore, we propose an onboard dustproof and temperature-controlled device for overhead crane positioning to address these issues. Utility Model Content

[0006] Preferably, a transmission seat is installed at the rear of the upper end of the cover plate, and a motor is installed at the rear end of the transmission seat. The output end of the motor passes through and extends into the interior of the transmission seat, and a drive shaft is installed thereon. One end of the drive shaft extends to the outside of the transmission seat and is connected to the mounting shell through a support. A cooling fan is installed on the outer wall of the drive shaft, and two cooling fans are provided.
[0007] Preferably, a driven shaft is installed inside the transmission base, with both ends of the driven shaft passing through and extending to both sides of the transmission base. An eccentric striking disc is installed at both ends of the driven shaft. A worm gear is installed on the outer wall of the drive shaft, and the worm gear is located inside the transmission base. A worm section is provided on the outer wall of the driven shaft, and the worm section is located inside the transmission base and is connected to the worm gear. A brush rod is provided on the outer side of the side heat dissipation groove. A transmission rod is installed above the rear end of the brush rod. A guide seat is installed on the outer wall of the transmission rod. The guide seat is fixedly connected to the mounting shell and slidably connected to the transmission rod. A strike plate is installed at the upper end of the transmission rod, and the strike plate is connected to the guide seat by a compression spring.
[0008] Preferably, a polytetrafluoroethylene (PTFE) scraper is installed on the inner wall of the brush rod, and the PTFE scraper and the brush rod are connected by nylon screws.
[0009] Preferably, the other end of the brush rod is provided with a guide strip, the inside of the guide strip is provided with a groove, the end of the brush rod is provided with a protrusion, and the brush rod is slidably connected to the groove through the protrusion.
[0010] Preferably, the upper surface of the cover plate is provided with a plurality of heat dissipation fins, and the lower ends of the heat dissipation fins extend into the interior of the mounting shell.
[0011] Preferably, foot pads are installed at all four corners of the lower end of the mounting shell.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. When using this utility model, the crane positioning device is placed in the mounting housing and positioned between four sets of triangular positioning blocks. Then, the handle is rotated to drive the bidirectional lead screw on one side to rotate. At the same time, the bidirectional lead screw on one side rotates through the synchronous pulley and synchronous belt, so that the bidirectional lead screws are synchronously transmitted, driving the four sets of triangular positioning blocks to move relative to each other in pairs, thereby clamping and fixing the crane positioning device. This solves the problem that in the use of existing crane GPS navigators, when the crane is working, the GPS navigator will be subjected to large vibrations, causing the navigator's data transmission and reception to malfunction or data loss.
[0014] 2. During the use of the overhead crane positioning device, the side heat dissipation slots on both sides of the mounting shell can play a role in ventilation and heat dissipation. The dustproof net inside the side heat dissipation slots can isolate dust. The upper surface of the cover plate is provided with several heat dissipation fins, and the lower end of the heat dissipation fins extends into the interior of the mounting shell. The heat dissipation fins can quickly conduct the heat generated by the overhead crane positioning device inside the mounting shell to the top. In conjunction with the motor output end driving the drive shaft and cooling fan to rotate, the heat dissipation of the fins can be accelerated, ensuring that the operating temperature of the GPS navigator is within the normal range.
[0015] 3. During the heat dissipation process, when the drive shaft rotates, it drives the driven shaft to rotate through the worm gear and the worm on the outer wall of the driven shaft. This causes the eccentric striking discs at both ends to rotate and strike the impact plate at the end of the transmission rod back and forth. The impact plate then drives the transmission rod and the brush rod at the end of the transmission rod to move up and down, brushing away the dust on the surface of the dustproof net and preventing dust from clogging the dustproof net.

The mounting shell 1 has side heat dissipation grooves 5 on both sides, and a dustproof mesh 6 is installed inside the side heat dissipation grooves 5. Two bidirectional lead screws 23 are mounted on both sides inside the mounting shell 1. The bidirectional lead screws 23 include a forward lead screw 231 and a reverse lead screw 232, one end of the forward lead screw 231 being fixedly connected to the reverse lead screw 232. The mounting housing 1 is equipped with bearing plates 233. A transmission cover 4 is installed at the front end of the mounting housing 1. The front ends of the two-way lead screws 23 on both sides extend through and into the interior of the transmission cover 4, and are equipped with synchronous pulleys 401. The synchronous pulleys 401 are connected by a synchronous belt 402. The rear end of one side of the two-way lead screw 23 extends through and into the exterior of the mounting housing 1, and is equipped with a handle 22. Slider blocks 24 are installed on both the forward lead screw 231 and the reverse lead screw 232 of the two-way lead screw 23. Triangular positioning blocks 25 are installed on the sliders 24. A rubber terminal sleeve 21 is installed at the rear end of the mounting housing 1.
[0023] Please see Figure 1-3 A transmission seat 13 is installed at the rear of the upper end of the cover plate 3. A motor 14 is installed at the rear end of the transmission seat 13. The output end of the motor 14 passes through and extends into the interior of the transmission seat 13, and a drive shaft 17 is installed thereon. One end of the drive shaft 17 extends to the outside of the transmission seat 13 and is connected to the mounting shell 1 via a support 19. Two cooling fans 18 are installed on the outer wall of the drive shaft 17. A driven shaft 15 is installed inside the transmission seat 13. Both ends of the driven shaft 15 pass through and extend to both sides of the transmission seat 13. An eccentric striking disc 16 is installed at both ends of the driven shaft 15. A worm gear is installed on the outer wall of the driven shaft 17, and the worm gear is located inside the transmission seat 13. A worm section is provided on the outer wall of the driven shaft 15. The worm section is located inside the transmission seat 13 and is connected to the worm gear. A brush rod 7 is provided on the outer side of the side heat dissipation groove 5. A transmission rod 9 is installed above the rear end of the brush rod 7. A guide seat 10 is installed on the outer wall of the transmission rod 9. The guide seat 10 is fixedly connected to the mounting shell 1 and slidably connected to the transmission rod 9. A strike plate is installed at the upper end of the transmission rod 9. The strike plate is connected to the guide seat 10 by a compression spring 11. Foot pads 2 are installed at the four corners of the lower end of the mounting shell 1.
[0024] In use, unlock the screws on cover plate 3, remove cover plate 3, and place the GPS navigator into the mounting housing 1, positioning it between the four sets of triangular positioning blocks 25. Then, rotate handle 22 to rotate one of the bidirectional lead screws 23. Simultaneously, the rotation of one bidirectional lead screw 23 drives the rotation of the other bidirectional lead screw 23 via synchronous pulley 401 and synchronous belt 402, ensuring synchronous transmission of the bidirectional lead screws 23. This causes the four sets of triangular positioning blocks 25 to move relative to each other, clamping and fixing the GPS navigator. After clamping, close cover plate 3. During use, the side heat dissipation grooves 5 on both sides of the mounting housing 1 provide ventilation and heat dissipation. The dustproof mesh 6 inside the side heat dissipation grooves 5 isolates dust. The upper surface of cover plate 3... The device is equipped with several heat dissipation fins 20, with the lower ends of the fins extending into the interior of the mounting housing 1. The heat dissipation fins 20 can quickly conduct the heat generated by the GPS navigator inside the mounting housing 1 to the top. In conjunction with the output of the motor 14 driving the drive shaft 17 and the cooling fan 18 to rotate, the heat dissipation of the fins can be accelerated, ensuring that the operating temperature of the GPS navigator is within the normal range. When the drive shaft 17 rotates, it drives the driven shaft 15 to rotate through the worm gear and the worm on the outer wall of the driven shaft 15. This causes the eccentric striking discs 16 at both ends to rotate and strike the impact plate at the end of the transmission rod 9 back and forth. The impact plate causes the transmission rod 9 and the brush rod 7 at the end of the transmission rod 9 to move up and down, brushing away the dust on the surface of the dustproof net 6, thus preventing the dust from clogging the dustproof net 6.
[0025] Furthermore, a polytetrafluoroethylene (PTFE) scraper 8 is installed on the inner wall of the brush rod 7. The PTFE scraper 8 and the brush rod 7 are connected by nylon screws.
