Description

Technical Field

[0001] This utility model relates to a crane track trolley maintenance and replacement device, belonging to the technical field of crane equipment maintenance tools in the metallurgical industry. Background Technology

[0002] The overhead crane track trolley is a power supply method for the crane's translation, hoisting mechanisms, and mobile operator's cab. All power control cables are fixed on its support plate, and it is synchronously moved by the trolley's support bracket. During daily operation, wear and tear on the cable trolley and pulley wheels frequently causes electrical slippage, which can severely damage cables and bend track supports. Therefore, regular inspection and replacement of the overhead crane track trolley and pulley wheels are necessary. Currently, due to the lack of specialized maintenance tools and the large amount of cables on the cable support plate, maintenance is done manually. This requires at least four people and two hours to complete the work, which is time-consuming, labor-intensive, and poses safety hazards. Utility Model Content

[0003] The purpose of this invention is to provide a crane track trolley maintenance and replacement device that can reduce the maintenance and replacement time of crane track trolleys and trolley wheels, and solve the problems existing in the background art.

[0004] The technical solution of this utility model is:

[0005] A crane track trolley maintenance and replacement device includes a torque wrench, a support base, a width adjusting screw, a traction screw, a positioning seat, a traction arm, and a nut. The support base is provided with a nut that is threadedly connected to the traction screw. The torque wrench is fixed to the upper end of the traction screw, and the lower end of the traction screw is rotatably connected to the positioning seat. The positioning seat cooperates with the I-beam of the track. The support base is provided with symmetrically arranged width adjusting screws on both sides. Each width adjusting screw is provided with a traction arm. The upper end of the traction arm is fixed to the width adjusting screw, and the lower end of the traction arm cooperates with the crane track trolley.

[0006] The positioning seat has a U-shaped structure.

[0007] The positioning seat is equipped with a bearing that cooperates with the traction screw.

[0008] The width adjusting screws symmetrically arranged on both sides of the support base are threaded onto the support base.

[0009] The traction arm on the width adjusting screw is L-shaped.

[0010] The nut is fixed to the support base.

[0011] The beneficial effects of this utility model are: when the crane cable trolley or pulley wheel malfunctions or wears out, it replaces traditional manual operation, reduces the maintenance and replacement time of the crane track trolley and pulley wheel, is easy to operate, is not limited by the site, has a compact structure, is lightweight, small in size, and is easy to carry.

[0014] Figure 3 This is a frontal comparison diagram of the lifting and lowering mechanism of this utility model;

[0015] In the diagram: Torque wrench 1, support seat 2, width adjusting screw 3, traction screw 4, positioning seat 5, traction arm 6, track I-beam 7, pulley wheel 8, pulley rod screw 9, towing cable support plate 10, nut 11, bearing 12. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and examples.

[0017] See attached document Figure 1-3 A crane track trolley maintenance and replacement device includes a torque wrench 1, a support base 2, a width adjusting screw 3, a traction screw 4, a positioning seat 5, a traction arm 6, and a nut 11. The support base 2 is provided with a nut 11 that is threadedly connected to the traction screw 4. The torque wrench 1 is fixed to the upper end of the traction screw 4, and the lower end of the traction screw 4 is rotatably connected to the positioning seat 5. The positioning seat 5 cooperates with the track I-beam 7. The support base 2 is provided with symmetrically arranged width adjusting screws 3 on both sides. Each width adjusting screw 3 is provided with a traction arm 6. The upper end of the traction arm 6 is fixed to the width adjusting screw 3, and the lower end of the traction arm 6 cooperates with the crane track trolley.

[0018] In this embodiment, refer to the appendix Figure 1-3 The maintenance and replacement device includes a torque lever 1, a support base 2, a width adjusting screw 3, a traction screw 4, a positioning seat 5, a traction arm 6, a nut 11, and a bearing 12, wherein:

[0019] Nut 11 is fixed at the center of support seat 2, torque wrench 1 is fixed at the top of traction screw 4, traction screw 4 passes through the matching nut 11 at the center of support seat 2, and the bottom is connected to bearing 12 at the center of positioning seat 5. Positioning seat 5 has a U-shaped structure.

[0020] The traction arm 6 is L-shaped, and there are four width adjusting screws 3 and four traction arms 6, which are symmetrically arranged on both sides of the support seat 2.

[0021] By rotating the torque lever 1 clockwise and counterclockwise, the traction screw 4 moves relative to the support seat 2, thereby converting the rotary motion into lifting motion.

[0022] See attached document Figure 1 , 2 3. During use, place the positioning seat 5 of the device stably above the I-beam 7 of the track, hook the traction arm 6 onto the base plate of the overhead crane trolley, adjust the distance using the width adjustment rod 3, loosen the trolley connecting rod screw 9, turn the torque wrench 1 clockwise, and the support seat 2 moves upward perpendicular to the track. The traction arm 6 drives the trolley wheel base plate to rise to the appropriate replacement position for trolley wheel replacement.

[0023] When the crane cable trolley or pulley wheel malfunctions or wears out, this repair and replacement device can reduce the workload from four people working for two hours to two people working for half an hour to complete the repair task. This greatly improves the efficiency and safety of pulley wheel replacement and reduces the risks and labor intensity of manual operation.
