Description

Technical Field

[0001] This utility model relates to the field of cable rack straightening technology, and more specifically, to a cable rack straightening device for power construction. Background Technology

[0002] In power construction projects, cable racks are important infrastructure for cable laying and support. Their geometric accuracy and structural integrity are directly related to the safe and reliable operation of the entire power system. Cable racks are widely used in various power engineering projects due to their good conductivity, corrosion resistance and structural strength. However, during transportation, storage and installation, structural defects such as deformation, twisting and bending are prone to occur, which affect their performance and installation quality.

[0003] Existing cable rack straightening devices generally use fixed-size clamping and straightening mechanisms. Key parameters such as clamp opening, support point spacing, and straightening force application position are designed and manufactured based on specific cable rack specifications. This one-to-one design mode means that the straightening device can only be applied to cable rack products of a single specification or a very narrow range. When faced with cable racks of different cross-sectional sizes, wall thicknesses, and lengths, existing straightening devices cannot achieve effective size matching and geometric adaptation. Either there is too large a gap between the clamp and the cable rack, resulting in insecure clamping, or there is dimensional interference, preventing normal clamping. This deficiency in size adaptability forces power construction units to equip cable racks of different specifications with corresponding special straightening devices, which not only increases equipment investment costs and storage management complexity, but more importantly, it is often impossible to accurately determine all specifications and models of the required cable racks in advance at the actual construction site, resulting in low efficiency of straightening operations.

A clamping plate 22 is coaxially provided on the outer surface of the sleeve 21. Multiple sets of connecting rods 23 are provided on the side wall of the clamping plate 22. The other end of the connecting rod 23 is connected to a connecting plate 24. Insert rods 25 are provided on the side wall of the connecting plate 24. A ring 26 is provided on the side wall of the connecting plate 24. A tension spring 27 is provided on the upper end face of the sleeve 21. A connecting sleeve 28 is provided on the other end of the tension spring 27. Multiple sets of sliding rods 29 are provided on the upper end face of the connecting sleeve 28. The sliding rods 29 are connected to the connecting plate 24. The sleeve 21 has multiple sets of round holes that are adapted to each other. The inner wall of the sleeve 21 has several sets of inclined grooves 210. The lower end of the connecting sleeve 28 has several sets of pull rods 211 that are adapted to the inclined grooves 210. The other end of the pull rod 211 is connected to a connecting spring 212. The other end of the connecting spring 212 is connected to a slider 213. The slider 213 is embedded in the inclined groove 210 and is slidably connected to the inclined groove 210. The side wall of the slider 213 is provided with a compression spring 214. The other end of the compression spring 214 is connected to an abutment plate 215. The side wall of the abutment plate 215 abuts against the surface of the insertion rod 25.

[0019] The operator places the cable frame between the first clamping roller 18, the second clamping roller 19, and the third clamping roller 117. The clamping rod 118 abuts against the surface of the cable frame. The operator rotates the push rod 115, which drives the lead screw 114 to move up or down, thereby driving the slide plate 116 to move up or down, and causing the third clamping roller 117 to move accordingly, clamping the upper surface of the cable frame. The clamping plates 22 at one end of the first clamping roller 18, the second clamping roller 19, and the third clamping roller 117 clamp the side wall of the cable frame. The operator starts the motor 12, which drives the drive wheel 13 to rotate, which in turn drives the driven wheel 15 to rotate through the belt 16. The rotation of the driven wheel 15 drives the reducer 14 to run, which in turn drives the drive shaft 110 to rotate, which drives the drive gear 111 to rotate. The drive gear 111 drives the driven gear 112 to rotate through the chain 113. The synchronous rotation of the drive gear 111 and the driven gear 112 drives the first clamping roller 18 and the second clamping roller 19 on the other side to rotate synchronously, clamping and conveying the cable frame forward to straighten the cable frame.

[0020] When the cable tray that needs to be corrected is changed in size, the clamping device needs to be replaced. The worker holds the ring 26 with both hands and presses the slide bar 29 with his thumbs. The slide bar 29 is subjected to inward squeezing force, which in turn drives the connecting sleeve 28 and the pull rod 211 to move into the sleeve 21. The connecting spring 212 at the other end of the pull rod 211 continues to push the slider 213 to move inward along the inclined slide groove 210. At this time, the contact state between the connecting plate and the surface of the insertion rod 25 can be released, and the insertion rod 25 and the clamping plate 22 connected to its side wall can be pulled out. When replacing the new clamping device, the round hole on the surface of the connecting plate 24 is aligned with the slide bar 29 and inserted. The insertion rod 25 is inserted into the sleeve 21. At this time, the tension spring 27 and the connecting spring 212 both provide outward pulling force to the slider 213. The compression spring 214 on the side wall of the slider 213 applies pressure to the abutment plate 215, so that the abutment plate 215 tightly abuts against the surface of the insertion rod 25, thereby achieving the fixed installation of the clamping device.
