DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example: See Figure 1-Figure 3 , the utility model provides a technical solution:

[0024] A high-voltage cable test device comprises a base frame 1, a mounting frame 2 is fixedly mounted on the front end of the top of the base frame 1, a clamping mechanism 3 is mounted on the top of the mounting frame 2, an adjusting frame 4 is fixedly mounted on the rear end of the top of the base frame 1, and a pulling mechanism 5 is mounted on the inner side of the adjusting frame 4.

[0025] First, in this embodiment, the specific structure of the clamping mechanism 3 is as follows:

[0026] The clamping mechanism 3 includes a telescopic cylinder 301 fixedly mounted on the bottom of the mounting frame 2, a top frame 302 is fixedly mounted on the driving end of the telescopic cylinder 301, the front and rear ends of the top frame 302 are symmetrically rotatably connected with transmission arms 303, the left and right ends of the top of the mounting frame 2 corresponding to the transmission arms 303 are rotatably connected with clamping arms 304, and the top of the transmission arms 303 is rotatably connected with the clamping arms 304, and the tops of the multiple groups of clamping arms 304 are fixedly mounted with clamping blocks 305, During the pulling test, one end of the high-voltage cable is passed through multiple groups of clamping blocks 305, and then the high-voltage cable is extended into the pulling mechanism 5 on the adjusting frame 4, and then the telescopic cylinder 301 is started to drive the top frame 302 to move downward, and under the transmission of the transmission arm 303, the multiple groups of clamping arms 304 are driven to swing synchronously to the outside of the high-voltage cable until the multiple groups of clamping blocks 305 clamp and fix the high-voltage cable, so that only one group of telescopic cylinders 301 is needed to fix the high-voltage cable, while ensuring the fixing effect of the high-voltage cable.

[0027] Furthermore, the bottom ends of the multiple groups of clamping arms 304 are rotatably connected to the mounting frame 2 via connecting rods 306, and the inner sides of the multiple groups of clamping blocks 305 are provided with arc-shaped clamping grooves 307. The bottom ends of the clamping arms 304 are rotated via the connecting rods 306, and the multiple groups of clamping blocks 305 clamp and fix the high-voltage cables via the inner arc-shaped clamping grooves 307.

[0028] Then, a fixing plate 401 is fixedly installed at both the front and rear ends of the right side of the adjusting frame 4, a locking block 402 is fixedly installed at the right end of the fixing plate 401, and a guide sleeve 403 is clamped between the fixing plate 401 and the locking block 402. When the high-voltage cable is extended into the pulling mechanism 5 on the adjusting frame 4, the high-voltage cable is guided by the guide sleeve 403.

[0029] Furthermore, the pulling mechanism 5 includes a fixed seat 501 fixedly installed at the bottom end of the inner side of the adjusting frame 4, the top of the inner side of the adjusting frame 4 is slidably connected with the adjusting seat 502, the top of the inner side of the adjusting frame 4 is threadedly connected with the adjusting rod 503, the right sides of the fixed seat 501 and the adjusting seat 502 are rotatably connected with the first roller 504 and the second roller 505 respectively, the top of the bottom frame 1 and the right side of the first roller 504 are fixedly installed with a motor 506, and the driving end of the motor 506 is connected to the first roller 504. The central axis is fixedly connected, and the high-voltage cable is extended between the first roller 504 and the second roller 505 through the guide sleeve 403. Then, the height of the adjustment seat 502 is adjusted so that the high-voltage cable is clamped and fixed between the first roller 504 and the second roller 505. After the other end of the high-voltage cable is fixed by multiple groups of clamping blocks 305, the motor 506 is started to drive the first roller 504 to rotate, so that the high-voltage cable is pulled by the first roller 504 and the second roller 505 for a pulling test.

[0030] Among them, a slide groove 507 is opened on the right side of the adjustment frame 4 and at the front and rear ends of the adjustment seat 502, and the front and rear ends of the adjustment seat 502 are slidably connected to the slide groove 507. When the height of the adjustment seat 502 is adjusted, the adjustment seat 502 moves stably through the slide groove 507.

[0031] Secondly, a rotating wheel 508 is fixedly installed on the top of the adjusting rod 503, and the bottom end of the adjusting rod 503 is rotatably connected to the adjusting seat 502 through the shaft sleeve 509. The rotating wheel 508 is operated to rotate the adjusting rod 503 to screw into the inner side of the adjusting frame 4, and then the adjusting seat 502 is lowered on the connection with the shaft sleeve 509.

[0032] Finally, a clamping groove 510 is provided on the inner side of the first roller 504 and the second roller 505, and a transmission gear 511 is fixedly installed on the left end of the central axis of the first roller 504 and the second roller 505, and the two sets of transmission gears 511 are meshed with each other. When the adjustment seat 502 is lowered, the high-voltage cable is located between the first roller 504 and the second roller 505, and the high-voltage cable is clamped and fixed by the inner clamping groove 510. At the same time, the two sets of transmission gears 511 are meshed with each other, so that when the motor 506 drives the first roller 504 to rotate, the second roller 505 is synchronously driven to roll under the transmission of the transmission gear 511, thereby stably pulling the high-voltage cable for test operation.

[0033] In this embodiment, the implementation scenario is specifically as follows: when performing a pulling test on a high-voltage cable, one end of the high-voltage cable is passed through multiple groups of clamping blocks 305, and then extended between the first roller 504 and the second roller 505 through the guide sleeve 403, and then the height of the adjustment seat 502 is adjusted so that the high-voltage cable is clamped and fixed between the first roller 504 and the second roller 505, and then the high-voltage cable is extended into the pulling mechanism 5 on the adjustment frame 4, and then the telescopic cylinder 301 is started to drive the top frame 302 to move downward, and the transmission arm 303 drives multiple groups of clamping blocks 305 to move downward. The clamping arms 304 are synchronously swung toward the outside of the high-voltage cable until the multiple clamping blocks 305 clamp and fix the high-voltage cable, and the start motor 506 drives the first roller 504 to rotate, so that the first roller 504 and the second roller 505 are used to pull the high-voltage cable for a pulling test. The entire operation process is simple and convenient. Compared with the existing high-voltage cable testing device, the utility model only needs one set of telescopic cylinders 301 to fix the high-voltage cable through design, while ensuring the fixing effect of the high-voltage cable, thereby greatly reducing the manufacturing cost of the device.
