Description

Technical Field

[0001] This invention relates to the field of communication engineering technology, and in particular to an electric paint scraper for communication engineering construction. Background Technology

[0002] In the field of communication engineering construction technology, according to relevant construction specifications, cable trays and battery vibration damping racks installed indoors in base stations must be reliably grounded. Currently, most telecommunications base stations require cable trays and battery vibration damping racks to be connected to lightning protection grounding. The grounding method is to first connect the cable trays and battery vibration damping racks in the base station with a flexible cable, and then connect them to the protective grounding bar through a grounding cable. However, since the cable trays and battery vibration damping racks are painted or powder coated for rust prevention when they leave the factory, the rust prevention layer must be scraped off to achieve a reliable connection between the flexible cable and the cable trays and battery vibration damping racks.

[0003] Existing electric paint scrapers are usually manually adjusted by workers to clamp the cable, which is cumbersome and inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide an electric paint scraper for communication engineering construction, which solves the problem of cumbersome clamping operation of existing electric paint scrapers.

[0005] To achieve the above objectives, the present invention provides an electric paint scraper for communication engineering construction. The electric paint scraper for communication engineering construction includes a wire clamp, a gripping assembly, and a fixing device. The fixing device is fitted under the wire clamp and slidably connected to the wire clamp. The gripping assembly is disposed on the side of the fixing device away from the wire clamp and is fixedly connected to the fixing device. The wire clamp includes a mounting block with a guide post, a sliding block, and a connecting rod. The mounting block is disposed above the fixing device and slidably connected to the fixing device. The guide post is disposed at the bottom of the mounting block and cooperates with the fixing device.

The end of the connecting rod away from the sliding block passes through the mounting block and the fixing device and is connected to the gripping assembly via a universal joint.

[0006] The connecting rod includes a connector and a pull rod. The connector is located on the side of the sliding block near the mounting block and is slidably connected to the sliding block. The pull rod is located on the side of the connector near the mounting block and is hinged to the connector. The end of the pull rod away from the connector passes through the mounting block and the retainer and is connected to the gripping assembly via a universal joint.

[0007] Place the cable between the sliding block and the mounting block, press the grip assembly, and the connecting rod will pull the sliding block toward the mounting block to clamp the cable.

[0008] The connector includes a sliding seat and a buffer spring. The sliding seat is disposed on the side of the sliding block near the mounting block and is slidably connected to the sliding block. The buffer spring is disposed between the sliding seat and the sliding block, and its two ends are fixedly connected to the sliding seat and the sliding block, respectively.

[0009] Once the cable is clamped, continue pressing the grip assembly; the pull rod pulls the sliding seat, and the buffer spring extends.

[0010] The fixture includes a fixed shell and a drive assembly. The fixed shell is located below the mounting block and is slidably connected to the mounting block. The fixed shell is also fixedly connected to the grip assembly. The drive assembly is located inside the fixed shell and cooperates with the guide post and the grip assembly, respectively.

[0011] After the cable is clamped, the drive assembly drives the mounting block and the sliding block to slide laterally to scrape the paint off the cable.

[0012] The drive assembly includes a roller and a motor. The roller is disposed inside the fixed housing and is rotatably connected to the fixed housing.

[0028] Please see Figures 1 to 5 This invention provides an electric paint scraper for communication engineering construction. The electric paint scraper includes a wire clamp 10, a gripping assembly 30, and a fixing device 20. The fixing device 20 is fitted below the wire clamp 10 and slidably connected to it. The gripping assembly 30 is disposed on the side of the fixing device 20 away from the wire clamp 10 and is fixedly connected to it. The wire clamp 10 includes a mounting block 12 with a guide post 14, a sliding block 11, and a connecting rod 13. The mounting block 12 is disposed above the fixing device 20 and is fixedly connected to it. The retainer 20 is slidably connected. The guide post 14 is disposed at the bottom of the mounting block 12 and cooperates with the retainer 20. The sliding block 11 is disposed on the side of the mounting block 12 away from the gripping component 30 and is slidably connected with the mounting block 12. The connecting rod 13 is disposed on the side of the sliding block 11 close to the mounting block 12 and is slidably connected with the sliding block 11. The end of the connecting rod 13 away from the sliding block 11 passes through the mounting block 12 and the retainer 20 and is connected to the gripping component 30 through a universal joint.

[0029] The connecting rod 13 includes a connector 131 and a pull rod 132. The connector 131 is located on the side of the sliding block 11 near the mounting block 12 and is slidably connected to the sliding block 11. The pull rod 132 is located on the side of the connector 131 near the mounting block 12 and is hingedly connected to the connector 131. The end of the pull rod 132 away from the connector 131 passes through the mounting block 12 and the retainer 20, and is connected to the gripping assembly 30 via a universal joint.

[0030] In this embodiment, the cable is placed between the sliding block 11 and the mounting block 12. Pressing the gripping component 30 causes the connecting rod 13 to pull the sliding block 11 toward the mounting block 12, and the cable clamp 10 tightens to clamp the cable. This simple operation solves the problem of cumbersome clamping operation in existing electric paint scrapers. Continuing to press the gripping component 30 causes the fixing device 20 to drive the mounting block 12 to slide laterally via the guide post 14, scraping the paint off the cable. The connector 131 is slidably connected to the sliding block 11, providing a buffer after the cable clamp 10 clamps the cable, allowing the gripping component 30 to be pressed further to accommodate cables of different thicknesses. Additionally, when the paint scraper's power is low, pressing the gripping component 30 allows the mounting block 12 to be manually driven to slide.

[0031] Furthermore, the connector 131 includes a sliding seat 1311 and a buffer spring 1312. The sliding seat 1311 is disposed on the side of the sliding block 11 near the mounting block 12 and is slidably connected to the sliding block 11. The buffer spring 1312 is disposed between the sliding seat 1311 and the sliding block 11, and both ends of the buffer spring 1312 are fixedly connected to the sliding seat 1311 and the sliding block 11, respectively.

[0032] The fixture 20 includes a fixing shell 21 and a driving component 22. The fixing shell 21 is disposed below the mounting block 12 and is slidably connected to the mounting block 12. The fixing shell 21 is fixedly connected to the gripping component 30. The driving component 22 is disposed inside the fixing shell 21 and cooperates with the guide post 14 and the gripping component 30 respectively.

[0033] The drive assembly 22 includes a roller 221 and a motor 222. The roller 221 is disposed inside the fixed housing 21 and is rotatably connected to the fixed housing 21. The motor 222 is disposed at one end of the roller 221 and is fixedly connected to the fixed housing 21. The roller 221 cooperates with the guide post 14 and the gripping assembly 30 respectively.

[0034] The roller 221 has a guide groove 2212 and a ratchet 2211. The guide groove 2212 spirals around the side of the roller 221 and cooperates with the guide post 14. The ratchet 2211 is located at the end of the roller 221 away from the motor 222 and cooperates with the gripping assembly 30.

[0035] In this embodiment, after the sliding block 11 and the mounting block 12 clamp the cable, the gripping assembly 30 is pressed further, the pull rod 132 pulls the sliding seat 1311, the buffer spring 1312 extends, the sliding block 11 and the mounting block 12 remain stationary, and the cable is continuously clamped. When the power is sufficient, the motor 222 starts after the cable is clamped, driving the roller 221 to rotate. The guide post 14 slides inside the guide groove 2212, guiding the mounting block 12 to slide laterally. When the power is insufficient, the gripping assembly 30 is pressed repeatedly to move the ratchet 2211, thereby manually pushing the roller 221 to rotate.

[0036] Furthermore, the grip assembly 30 includes a fixed handle 31 and a movable handle 32. The fixed handle 31 is disposed on the side of the retainer 20 away from the mounting block 12 and is fixedly connected to the retainer 20. The movable handle 32 is disposed below the fixed handle 31 and is hinged to the fixed handle 31. The movable handle 32 is hinged to the connecting rod 13 and cooperates with the retainer 20.

[0037] The fixed handle 31 includes a grip 311 and a collar 312. The grip 311 is disposed on the side of the retainer 20 away from the mounting block 12 and is fixedly connected to the retainer 20. The grip 311 is hinged to the movable handle 32. The collar 312 is simultaneously fitted on the outside of the grip 311 and the movable handle 32, and the collar 312 is slidably connected to the grip 311.

[0038] The movable handle 32 includes a rotating rod 321 with a slot 322 and a pawl 323. The rotating rod 321 is located below the handle 311 and is hinged to the handle 311. The slot 322 is located on one side of the rotating rod 321. The pawl 323 is located inside the slot 322 and is slidably connected to the slot 322. The pawl 323 engages with the ratchet 2211.

[0039] The pawl 323 has a rotating shaft 3231 and a pull ring 3232. The rotating shaft 3231 is located on the side of the pawl 323 closer to the rotating rod 321, and the rotating shaft 3231 is slidably connected to the rotating rod 321. The pull ring 3232 is located on the side of the pawl 323 away from the rotating shaft 3231.

[0040] In this embodiment, pressing the movable handle 32 and the fixed handle 31 causes the rotating rod 321 to rotate on the grip 311. The movable handle 32 pulls the sliding block 11 via the pull rod 132, which, in conjunction with the mounting block 12, clamps the cable. When the power is insufficient, pulling the pull ring 3232 causes the rotating shaft 3231 to slide inside the slot 322, removing the pawl 323 from the slot 322. When the rotating rod 321 is fully open, rotating the pawl 323 removes the pawl 323 from the slot. Insert 23 into the fixed housing 21 to switch the paint scraper to manual mode. In the clamped state, repeatedly press the rotating rod 321. The pawl 323 pushes the roller 221 to rotate through the ratchet 2211, so that the paint scraper can be manually driven to work when the power is insufficient. During manual operation, slide the collar 312. The collar 312 cooperates with the rotating rod 321 to prevent the rotating rod 321 from opening too much, which would cause the sliding block 11 to loosen the cable and the pawl 323 to fall out of the fixed housing 21.

[0041] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
