[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Reference Figures 1-4 A workbench 1 for storing a reel drive shaft, comprising a workbench 1, a lifting frame 2 is fixedly connected to the back of the workbench 1, the lifting frame 2 comprises two vertical guide rods and a horizontal rod fixed to the upper ends of the two guide rods, the height of the horizontal rod is greater than the upper surface of the workbench 1, two guide rods of the lifting frame 2 are vertically slidably provided with adjusting assemblies 3 respectively, the adjusting assembly 3 comprises a moving block 301 slidably arranged on the surface of the guide rod and an adjusting rod 302 horizontally slidably arranged in the moving block 301, two adjusting rods 302 are respectively provided with bearing assemblies 4 at the back, two adjusting rods 302 are respectively fixedly connected with handles at the outer ends, and the back of the moving block 301 is provided with locking bolts for fixing the position of the adjusting rod 302.

[0023] It can be understood that the moving block 301 is vertically slidably arranged on the surface of the lifting frame 2, so that the bearing assembly 4 can drive the drive shaft to a position higher than the top of the workbench 1, the two adjusting rods 302 are horizontally slidably arranged in the moving block 301, so that the two bearing assemblies 4 are close to or away from each other, thereby facilitating the support of the two ends of the drive shaft of different lengths, and being suitable for different models of drive shafts, and under the action of the locking bolt, the position of the adjusting rod 302 can be limited.

[0024] Specifically, the bearing assembly 4 comprises a bearing rod 401 hingedly connected to the back of the inner end of the adjusting rod 302, the lower surface of the bearing rod 401 is fixedly connected with a limit block 402 for keeping the bearing rod 401 in a horizontal position, the other end of the limit block 402 abuts against the back of the adjusting rod 302, and the upper surface of the bearing rod 401 is an arc surface with a downward groove.

[0025] It can be understood that the bearing rod 401 is provided with an arc surface, which facilitates the placement of the transmission shaft, adapts to the use of transmission shafts of different diameters, prevents the transmission shaft from slipping off the surface of the bearing rod 401 during lifting or lowering, and is hinged to rotate on the back of the adjusting rod 302. When the bearing rod 401 moves downward from directly above the transmission shaft, the transmission shaft pushes the bearing rod 401 to rotate upward, avoids, and smoothly moves the bearing rod 401 below the transmission shaft. The bearing rod 401 rotates to the horizontal under the action of gravity, is supported by the limiting rod to keep it horizontal, and is lifted upward by the transmission shaft through the bearing rod 401 by moving the adjusting rod 302 upward.

[0026] Specifically, the moving block 301 is driven upward by two groups of lifting assemblies 5, and the two groups of lifting assemblies 5 are arranged on both sides of the lifting frame 2. The lifting assembly 5 includes a winding wheel 501 and a guide wheel 502 fixed to the upper surface of the cross bar of the lifting frame 2.

[0027] It can be understood that the double-head motor drives the two winding wheels 501 to rotate simultaneously, thereby winding the two pull ropes 503, and under the action of the guide wheel 502, the moving block 301 is driven to slide upward on the surface of the lifting frame 2, thereby lifting the transmission shaft. The double-head motor drives the two winding wheels 501 to rotate in opposite directions, gradually releasing the pull rope 503, and the two groups of adjusting assemblies 3 slide downward under the action of gravity.

[0028] Specifically, the upper surface of the workbench 1 is provided with a support assembly 6 for pulling the transmission shaft to the surface of the workbench 1. The support assembly 6 includes two trapezoidal sliding rails 601 fixed to the upper surface of the workbench 1.

[0029] It can be understood that when the transmission shaft is lifted to be higher than the height of the supporting blocks 603, the sliding frame 602 is pushed to slide on the surfaces of the two slide rails 601, the two supporting blocks 603 are moved to be below the transmission shaft, the carrying rod 401 drives the transmission shaft to move downwards, the transmission shaft is placed on the surfaces of the two supporting blocks 603, then the sliding frame 602 is pulled, the supporting blocks 603 and the transmission shaft are moved to the surface of the workbench 1, and the sliding frame 602 is fixed through the locking bolts, so that the transmission shaft is prevented from moving in the detection process, the V-shaped grooves are arranged, and therefore different diameter transmission shafts can be conveniently supported and used.

[0030] In the utility model, the drawer type storage rack with the transmission shaft is moved to the back of the workbench 1, the transmission shaft layer frame to be detected is pulled out of the range of the storage rack, the two adjusting rods 302 are transversely slid in the moving blocks 301, the two groups of carrying assemblies 4 are close to or away from each other, the carrying assembly 4 is adjusted to the positions of the two ends of the transmission shaft, the double-head motor drives the two winding wheels 501 to gradually release the pull ropes 503, the two groups of adjusting assemblies 3 slide downwards under the action of gravity, the carrying rod 401 moves downwards from the position directly above the transmission shaft, when the carrying rod 401 contacts the transmission shaft, the carrying rod 401 is pushed upwards by the transmission shaft to avoid, the carrying rod 401 is smoothly moved to be below the transmission shaft, the carrying rod 401 rotates to be horizontal under the action of gravity, the carrying rod 401 is supported by the limiting rods and kept horizontal, the double-head motor drives the two winding wheels 501 to wind the two pull ropes 503, under the action of the guide wheels 502, the moving blocks 301 slide upwards on the surface of the lifting frame 2, the transmission shaft is lifted, the transmission shaft is driven to be higher than the top of the workbench 1, then the sliding frame 602 is pushed to slide on the surfaces of the two slide rails 601, the two supporting blocks 603 are moved to be below the transmission shaft, the carrying rod 401 drives the transmission shaft to move downwards, the transmission shaft is placed on the surfaces of the two supporting blocks 603, then the sliding frame 602 is pulled, the supporting blocks 603 and the transmission shaft are moved to the surface of the workbench 1, and the sliding frame 602 is fixed through the locking bolts, so that the transmission shaft is prevented from moving in the detection process, the purpose that the transmission shaft is easily lifted to the surface of the workbench 1 is achieved, when the detection is completed, the carrying rod 401 is moved downwards to be below the surface of the workbench 1, the transmission shaft is pushed to be above the carrying rod 401 through the sliding frame 602, the carrying rod 401 moves upwards and alternately puts the transmission shaft on the surface of the carrying rod 401, and the sliding frame 602 is pulled back, so that the carrying rod 401 drives the transmission shaft to move downwards, and therefore the detected transmission shaft is placed back on the surface of the layer frame of the storage rack.
