[0026] See also Figure 1-6 , a rapid detection device for the bonding strength of a shock-absorbing pad of an elevator traction machine comprises a device body 1, a connector body 2, a shock-absorbing pad body 3, a fixing body 4 and a top plate 8. A cylinder 5 is embedded on the left side of the top of the device body 1, and a push plate 6 is bolted to the output shaft of the cylinder 5. A groove 18 is provided on the right side of the top of the device body 1, and the fixing body 4 is slidably connected to the inner wall of the groove 18. An inner groove 9 is provided inside the device body 1, and the front and rear sides of the inner cavity of the inner groove 9 are respectively rotatably connected with a first rotating rod 10 and a second rotating rod 11. The top ends of the first rotating rod 10 and the second rotating rod 11 are both penetrated to the top of the device body 1 and are bolted with a threaded rod 12, and the top end of the threaded rod 12 is rotatably connected to the bottom of the top plate 8. A moving block 7 is arranged below the top plate 8, and a connecting plate 13 is bolted to the front and rear sides of the moving block 7, and the threaded rod 12 penetrates the connecting plate 13 and is threadedly connected thereto, and the bottom of the moving block 7 is fixedly installed with a fixed plate through a connecting rod The fixed block 14 has a card slot 16 at the bottom, and the top of the connector body 2 is slidably connected to the inner wall of the card slot 16. The front and rear sides of the fixed block 14 are bolted with a bent rod 15, and the bottom end of the bent rod 15 is bolted with a cross plate 17. A driving mechanism 19 is arranged inside the inner groove 9, and a collecting mechanism 20 is arranged on the left side of the device body 1. Through the arrangement of the cylinder 5, the push plate 6, the moving block 7, the inner groove 9, the first rotating rod 10, the second rotating rod 11, the threaded rod 12, the connecting plate 13, the fixed block 14, the bent rod 15, the card slot 16, the cross plate 17, the groove 18 and the driving mechanism 19, the device can quickly fix the shock-absorbing pad, and can delete the disassembly and assembly steps, and improve the detection efficiency, which solves the problem that when the shock-absorbing pad is currently detected, the connector and the fixing part of the shock-absorbing pad need to be fixed to the operating table by fixing bolts, which makes the detection steps cumbersome and affects the detection efficiency.

[0027] In this embodiment, the driving mechanism 19 includes a motor 191, a pulley 192, a first belt pulley 193 and a second belt pulley 194. The pulley 192 is clamped with the output shaft of the motor 191, and the first belt pulley 193 and the second belt pulley 194 are bolted to the surfaces of the first rotating rod 10 and the second rotating rod 11 respectively, and the pulley 192, the first belt pulley 193 and the second belt pulley 194 are connected to each other by belt transmission. Through the arrangement of the motor 191, the pulley 192, the first belt pulley 193 and the second belt pulley 194, the effect of providing power for the rotation of the first rotating rod 10, the second rotating rod 11 and the threaded rod 12 is achieved.

[0028] In this embodiment, a controller 26 is disposed on the left side of the front of the device body 1 , and the controller 26 is electrically connected to the motor 191 . The controller 26 is configured to control the motor 191 .

[0029] In this embodiment, the lengths of the threaded rods 12 at the tops of the first rotating rod 10 and the second rotating rod 11 are the same, and the directions of the threads on the surfaces of the two threaded rods 12 are the same. This design allows the front and rear threaded rods 12 to rotate while the connecting plates 13 on both sides move upward or downward synchronously, thereby increasing the stability of the moving block 7 during the up and down movement.

[0030] In this embodiment, the collection mechanism 20 includes a support plate 201, a collection box 202 and a slope 203. The support plate 201 and the slope 203 are both bolted to the right side of the device body 1. The collection box 202 is arranged on the top of the support plate 201, and the right side of the slope 203 extends to the top of the collection box 202. Through the arrangement of the support plate 201, the collection box 202 and the slope 203, if the shock-absorbing pad body 3 is not firmly bonded to the fixing parts and the connecting parts, it will move to the right under the action of the push plate 6 and reach the inside of the collection box 202 through the slope 203, thereby achieving the effect of collecting unqualified shock-absorbing pads.

[0031] In this embodiment, a baffle 21 is bolted to the right side of the top of the collection box 202, and a soft pad 22 is arranged inside the collection box 202. Through the arrangement of the baffle 21 and the soft pad 22, if the pressure of the push plate 6 is too large and causes the shock-absorbing pad body 3 to fly out, the baffle 21 can block the shock-absorbing pad body 3, and the soft pad 22 can prevent the shock-absorbing pad body 3 from falling into the collection box 202, causing damage to the collection box 202 or the shock-absorbing pad body 3.

[0032] In this embodiment, vertical plates 23 are bolted to the front and rear sides of the top of the slope 203, and the inclination angle of the vertical plates 23 is the same as the inclination angle of the slope 203. The vertical plates 23 are arranged to prevent the shock-absorbing pad body 3 from falling from the front and rear sides when sliding on the surface of the slope 203.

[0033] In this embodiment, a rubber pad 24 is bonded to the bottom of the horizontal plate 17, and a protrusion 25 is provided at the bottom of the rubber pad 24. Through the setting of the rubber pad 24 and the protrusion 25, their coordinated use can increase the friction between the horizontal plate 17 and the fixing body 4, so as to improve the fixing effect.

[0034] In this embodiment, the push plate 6 is overall arc-shaped, and the upper and lower heights of the push plate 6 are less than the thickness of the shock-absorbing pad body 3. This design enables the push plate 6 to be tightly attached to the surface of the shock-absorbing pad body 3, so that the force on the shock-absorbing pad body 3 is more evenly applied. At the same time, the push plate 6 will not touch the connector body 2 or the fixing body 4 during movement to avoid affecting the detection results.

[0035] In this embodiment, the area of ​​the bottom of the inner wall of the groove 18 is larger than the area of ​​the bottom of the fixing body 4, and the depth of the groove 18 is less than the thickness of the fixing body 4. This design can prevent the groove 18 from being too deep, causing a portion of the shock-absorbing pad body 3 to be located inside the groove 18 and affecting the detection operation.

[0036] Working principle: When working, first pick up the shock-absorbing pad to align the fixing body 4 with the groove 18, then put down the shock-absorbing pad to place the fixing body 4 inside the groove 18, and at the same time turn on the motor 191, which drives the pulley 192, the first belt pulley 193 and the second belt pulley 194 to start rotating, and the first rotating rod 10, the second rotating rod 11 and the threaded rods 12 on both sides start rotating together. At this time, the connecting plates 13 on the front and rear sides drive the moving block 7, the fixing block 14, the bending rod 15 and the cross plate 17 to move downward together under the action of the thread until the top of the connecting body 2 is located inside the slot 16, then turn off the motor 191, and at the same time, the rubber pad 24 and the protrusion 25 at the bottom of the cross plate 17 are close to the surface of the fixing body 4. At this time, the connecting body 2 and The fixing part body 4 is in a limited state, and at the same time, the cylinder 5 is turned on, and its output shaft extends and drives the push plate 6 to move to the right. Then the push plate 6 is close to the surface of the shock-absorbing pad body 3 and exerts a force to the right, and then the thrust of the cylinder 5 is increased to the set value. If the shock-absorbing pad is not firmly bonded, the shock-absorbing pad body 3 will loosen under the force and separate from the fixing part body 4 and the connecting part body 2. If the bonding strength is qualified, the shock-absorbing pad body 3 will not move. After the detection is completed, the motor 191 is turned on to make the fixing block 14 rise and release the limit on the connecting part body 2, and then the shock-absorbing pad can be taken out. During the detection process, the device can quickly fix the fixing plate and the connecting part of the shock-absorbing pad without the use of fixing bolts, and improve the detection efficiency of the device.
