Description

Technical Field

[0001] This utility model relates to the field of rope groove detection, and in particular to a fixture for detecting the wear of traction sheave rope grooves. Background Technology

[0002] With the increasing number and height of construction projects, elevators have become an indispensable means of transportation in construction projects. Elevator drive methods are generally divided into hydraulic drive, forced drive, and traction drive, among which traction drive is the most common. During the long-term operation of traction drive elevators, the traction sheave rope groove is prone to wear. When the wear is severe, it will affect the performance of the traction elevator, create safety hazards, and may lead to elevator accidents. At present, the detection method of rope groove wear of elevator traction sheaves is relatively complex. The detection requires the use of various precision instruments, which is costly. Moreover, different detection instruments are generally required to test different models of traction sheaves, making the measurement cumbersome and impractical. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a traction sheave groove wear detection fixture.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a traction sheave groove wear detection fixture, including a fixed base, a receiving controller fixedly connected to the bottom end of the fixed base, a clamping assembly provided on the outer surface of the fixed base, the clamping assembly including an electric push rod, a pulling rod movably connected to the end of the electric push rod away from the fixed base, a pulling block fixedly connected to the end of the pulling rod away from the electric push rod, two movable rods fixedly connected to the side of the pulling block away from the pulling rod, and a measuring clamping block movably sleeved on the outer surface of the movable rod.

[0005] As a preferred technical solution of this utility model, the bottom end of the measuring clamp block is fixedly connected to the fixed base, the outer surface of the measuring clamp block is provided with a measuring component, the end of the movable rod away from the measuring clamp block is fixedly connected to the measuring pressure block, the outer surface of the pull rod is provided with an auxiliary cleaning component, the cleaning component includes two pull arms, the two sides of the pull arms near the fixed base are movably connected to the electric push rod, and the side of the pull arm away from the electric push rod is movably connected to the oil leakage box.

[0006] As a preferred technical solution of this utility model, a swing arm is movably connected at the center of the pulling arm, and a connecting block is movably connected to the side of the swing arm away from the pulling arm. A rust-removing brush plate is movably sleeved on the outer surface of the oil leakage box. A semi-circular opening is provided at the top of the rust-removing brush plate. The measuring component includes several return springs. A sliding block is fixedly connected to the bottom of the return spring. A fitting card is fixedly connected to the side of the sliding block away from the return spring.

[0007] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0008] 1. This utility model uses an electric push rod to drive a multi-stage linkage mechanism to form a progressive clamping force. When the measuring pressure block contacts the rope, the hydraulic system can automatically adjust the clamping force to avoid rope deformation errors caused by excessive clamping or slippage caused by excessive clamping in traditional clamps.

[0009] 2. This utility model adopts a displacement feedback structure of a reset spring and a sliding block. The displacement of the contact card is triggered by the free sliding of the traction rope. Combined with the spring deformation, dynamic wear detection is achieved. The automatic spring reset design eliminates the need for manual calibration.

[0010] 3. This utility model integrates clamping and inspection with cleaning and rust removal functions through a linkage mechanism. During the clamping process, rust removal and lubricant application are completed simultaneously on the surface of the rope. Compared with traditional step-by-step inspection equipment, this not only avoids rust residue from aggravating rope groove wear, but also completes preventive maintenance during the inspection process, extending the service life of the traction system.

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0018] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a fixed base 1, and a receiver controller 2 is fixedly connected to the bottom end of the fixed base 1. The receiver controller 2 is a PCL controller. A clamping assembly is provided on the outer surface of the fixed base 1. The clamping assembly includes an electric push rod 3, which is a Shenli LW new type push rod. A pull rod 4 is movably connected to the end of the transmission rod of the electric push rod 3 away from the fixed base 1. A pull block 5 is fixedly connected to the end of the pull rod 4 away from the electric push rod 3. Two movable rods 6 are fixedly connected to the side of the pull block 5 away from the pull rod 4. A measuring clamping block 7 is movably sleeved on the outer surface of the movable rod 6.

[0019] When the elevator performs rope groove testing, the equipment receives instructions from the elevator control system via receiver controller 2. Receiver controller 2 controls the electric push rod 3 to retract. The retraction of the electric push rod 3 drives the pull rod 4 to retract inward. The retraction of the pull rod 4 drives the pull block 5 and the movable rod 6 to retract inward. After the movable rod 6 retracts inward, it drives the measuring pressure block 8 to retract inward to clamp the elevator traction rope. After clamping, the measuring component detects the descent distance of the traction rope, thereby avoiding the inaccuracies of manual testing methods.

[0020] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the bottom end of the measuring clamping block 7 is fixedly connected to the fixed base 1. The outer surface of the measuring clamping block 7 is provided with a measuring component. The end of the movable rod 6 away from the measuring clamping block 7 is fixedly connected to the measuring pressure block 8. The outer surface of the pull rod 4 is provided with an auxiliary cleaning component. The cleaning component includes two pull arms 9. The two sides of the pull arms 9 near the fixed base 1 are movably connected to the electric push rod 3. The side of the pull arm 9 away from the electric push rod 3 is movably connected to the oil leakage box 12.

[0021] When the traction rope is clamped, the pull rod 4 retracts inward, causing the two swing arms 10 to retract inward. The two swing arms 10 retract inward, causing the connecting block 11 to retract inward. The connecting block 11 retracts inward, causing the two pull arms 9 to contract towards the center of the pull rod 4. The two pull arms 9 compressing towards the center of the pull rod 4 causes the two oil leakage boxes 12 and the rust removal brush plate 13 to slide towards the center of the pull rod 4. During the sliding process, the rust on the outer surface of the traction rope is removed, preventing the rust on the outer surface of the traction rope from causing accelerated wear of the rope groove.

[0022] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a swing arm 10 is movably connected to the center of the pull arm 9, and a connecting block 11 is movably connected to the side of the swing arm 10 away from the pull arm 9. A rust removal brushing plate 13 is movably sleeved on the outer surface of the oil leakage box 12. A semi-circular opening is provided at the top of the rust removal brushing plate 13. The measuring component includes several return springs 14. A sliding block 15 is fixedly connected to the bottom end of the return spring 14. A fitting clip 16 is fixedly connected to the side of the sliding block 15 away from the return spring 14.

[0023] When the traction rope is clamped and measured, the measuring clamping block 7 and the measuring pressure block 8 clamp the traction rope. The traction rope slides downward between the measuring clamping block 7 and the measuring pressure block 8. The downward sliding of the traction rope causes the bonding card 16 to slide downward along the square sliding block 16 set behind the measuring clamping block 7. The downward sliding of the bonding card 16 causes the return spring 14 and the sliding block 15 to slide downward. When the traction rope stops sliding down, the clamping assembly receives the detection completion signal, and the pull rod 4 pushes outward to cause the measuring pressure block 8 to cancel the clamping of the traction rope. At this time, the downward force of the traction rope on the bonding card 16 disappears, and the return spring 14 rebounds and resets. The rebound of the return spring 14 causes the sliding block 15 and the bonding card 16 to rebound and reset, and the bonding card 16 rebounds and resets to facilitate the next detection.

[0024] Working principle:

[0025] Please refer to Figures 1-5 As shown, when the elevator performs rope groove detection, the equipment receives instructions from the elevator control system via the receiver controller 2. The receiver controller 2 controls the electric push rod 3 to retract, which in turn drives the pull rod 4 to retract inward. The retraction of the pull rod 4 inward drives the pull block 5 and the movable rod 6 to retract inward. After the movable rod 6 retracts inward, it drives the measuring pressure block 8 to retract inward to clamp the elevator traction rope. After clamping, the measuring component detects the descent distance of the traction rope, thus avoiding the inaccuracies of manual detection methods.

[0026] When the traction rope is clamped, the pull rod 4 retracts inward, causing the two swing arms 10 to retract inward. The two swing arms 10 retract inward, causing the connecting block 11 to retract inward. The connecting block 11 retracts inward, causing the two pull arms 9 to contract towards the center of the pull rod 4. The two pull arms 9 compressing towards the center of the pull rod 4 causes the two oil leakage boxes 12 and the rust removal brush plate 13 to slide towards the center of the pull rod 4. During the sliding process, the rust on the outer surface of the traction rope is removed, preventing the rust on the outer surface of the traction rope from causing accelerated wear of the rope groove.

[0027] When the traction rope is clamped and measured, the measuring clamping block 7 and the measuring pressure block 8 clamp the traction rope. The traction rope slides downward between the measuring clamping block 7 and the measuring pressure block 8. The downward sliding of the traction rope causes the bonding card 16 to slide downward along the square sliding block 16 set behind the measuring clamping block 7. The downward sliding of the bonding card 16 causes the return spring 14 and the sliding block 15 to slide downward. When the traction rope stops sliding down, the clamping assembly receives the detection completion signal, and the pull rod 4 pushes outward to cause the measuring pressure block 8 to cancel the clamping of the traction rope. At this time, the downward force of the traction rope on the bonding card 16 disappears, and the return spring 14 rebounds and resets. The rebound of the return spring 14 causes the sliding block 15 and the bonding card 16 to rebound and reset, and the bonding card 16 rebounds and resets to facilitate the next detection.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
