Description

Technical Field

[0001] This utility model relates to the field of cable-hauling machinery maintenance technology, specifically to an auxiliary device for changing the wheels of a cable-hauling trolley. Background Technology

[0002] The cable trolley is an indispensable and important component of overhead crane cable conveying. For overhead cranes in steel rolling mills, due to the high power of the main hook motor and the numerous protection measures, a separate cable is required to bring the field signals to the control cabinet. This cable needs to move with the trolley, requiring the cable trolley to fix these cables while simultaneously moving with the trolley. However, the load-bearing capacity of the cable trolley wheels is usually limited. During on-site production, the overhead crane trolley moves frequently and operates at a very fast pace. The reciprocating motion of the cable trolley is frequent, and the wheels are mostly operating under full load or even overload conditions, resulting in a very short service life for the cable trolley. Due to the special nature of the cable trolley, the wear and tear is mainly on the wheels, while other components of the cable trolley can still be used normally. To reduce maintenance costs, the cable trolley wheels are usually replaced.

[0003] When replacing the trolley wheels, maintenance personnel need to disconnect the power supply to the entire trolley, then remove the cables locked under the trolley to release the load, remove the single-sided wheel bolts and take off the single-sided wheel, allowing the trolley to be taken off the line as a whole. After replacing the wheels offline, the trolley is then installed on the overhead crane trolley cable track. Finally, the cables are fixed one by one to the load-bearing points under the trolley. This process is extremely tedious and requires a lot of working time. Taking the electromagnetic crane for bar and wire production as an example, each wheel needs to be inspected every week, and the wheels need to be replaced approximately every 30 days. This replacement method not only requires the crane to be stopped and the power to be cut off, but also requires a lot of time and manpower, resulting in more downtime on the production line, affecting the crane's operating rate, and failing to meet the requirements of smooth production and operation. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for changing the wheels of a cable trolley, so as to solve the problem that when changing the wheels of a cable trolley, it is necessary not only to cut off the power supply of the entire vehicle, but also to spend a lot of time and manpower, resulting in a lot of downtime on the production line, affecting the operation rate of the overhead crane, and failing to meet the problem of smooth production and operation of the production line.

[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: an auxiliary device for changing the wheels of a cable trolley, including a connecting plate and a hand-held electric drill. Two U-shaped frames are provided on both sides of the connecting plate. A base support can be detachably connected to each U-shaped frame. A bolt is threaded through the top plate. One end of the bolt is connected to the top plate, and the other end is provided with a connector. The bolt is detachably connected to the hand-held electric drill through the connector.

[0006] The principle and beneficial effects of this utility model are as follows: A handheld electric drill is used to rotate the bolt, thereby moving the connecting plate up and down. The connecting plate then moves the U-shaped frame up and down. The bottom support on the U-shaped frame abuts against the bottom of the cable-hauling trolley, causing the trolley to move up and down. When the trolley moves upward, the wheels leave the H-beam, allowing workers to replace them. When the trolley moves downward, the replaced wheels rest against the H-beam, thus completing the wheel replacement process. This auxiliary device allows for quick and convenient wheel replacement of the cable-hauling trolley, replacing manual lifting of the trolley, reducing worker workload, shortening wheel replacement time, minimizing downtime, and accelerating production line speed.

[0007] Option 2, a preferred option of the basic design, features a connector with one concave circular side and the other concave hexagonal side. The concave circular side engages with the drill bit of the hand drill, while the concave hexagonal side engages with the end of the bolt. Designing the connector so that both ends respectively engage with the drill bit and the bolt end increases the stability of the screw during rotation.

[0008] Option 3, the preferred option of the basic design, features a series of movable pins that pass through the U-shaped frame and the base. These pins connect the base to the U-shaped frame, and the base can be removed by pulling out the pins when not in use.

[0009] Option 4, a preferred option of the basic design, involves hinged connections between the U-shaped frame and the base. A connecting rod is located at the free end of the base. A slotted hole is located at the end of the U-shaped frame separated from the base, and the connecting rod engages with this slotted hole. By hinged connections between the U-shaped frame and the base, the base is rotated from a vertical to a horizontal position when using the device, allowing the connecting rod on the base to engage with the slotted hole in the U-shaped frame. When not in use, the connecting rod can be removed from the U-shaped frame.

[0010] Option 5, a preferred option from Option 3 or Option 4, includes fixing rods on the U-shaped frame. During use, the cable trolley needs to be lifted upwards; adding fixing rods increases the stability and robustness of the U-shaped frame.

[0011] Option six, an optimal choice from option five, uses an aluminum alloy U-shaped frame. The aluminum alloy material allows the U-shaped frame to maintain strength while reducing its weight, thus reducing the workload for workers.

[0012] Option 7, a preferred option of Option 3 or Option 4, features a rubber layer on the base. When the bottom of the cable trolley rests against the base, the rubber layer generates friction on the bottom of the cable trolley, preventing it from slipping and shifting during wheel replacement.

[0018] Example 1

[0019] The basic implementation examples are as follows: Figure 1 and attached Figure 2 As shown: A wheel replacement auxiliary device for a cable-hauling trolley includes a connecting plate 1 and a handheld electric drill 2. Two U-shaped frames 3 are provided on both sides of the connecting plate 1. A base support 4 is detachably connected to each U-shaped frame 3. A bolt 5 is threaded through the connecting plate 1. One end of the bolt 5 is connected to a top plate 6, and the other end is provided with a connector 7. The bolt 5 is detachably connected to the handheld electric drill 2 through the connector 7. One side of the connector 7 is circularly concave, and the other side is hexagonally concave. The circularly concave side of the connector 7 engages with the drill bit of the handheld electric drill 2, and the hexagonally concave side of the connector 7 engages with the end of the bolt 5. Pins 8 are movably inserted through the U-shaped frames 3 and the base support 4 in sequence. Each U-shaped frame 3 is provided with a fixing rod 11. The base support 4 is provided with a rubber layer. The U-shaped frames 3 are made of aluminum alloy.

[0020] The specific implementation method of this embodiment is as follows:

[0021] When replacing the wheels of the cable trolley, first hang the U-shaped frame 3 on the I-beam, at which point the connecting plate 1 abuts against the I-beam. Then place the base support 4 in the middle of the U-shaped frame 3 and connect the U-shaped frame 3 and the base support 4 using the pin 8. After fixing, start the hand-held electric drill 2 to rotate the bolt 5. The connecting plate 1 gradually moves upward through the rotation of the bolt 5, while simultaneously moving the U-shaped frame 3 upward. The base support 4 on the U-shaped frame 3 abuts against the bottom of the cable trolley, causing the entire cable trolley to move upward. After the cable trolley moves upward, the wheels leave the I-beam, and the workers replace the wheels. After the wheels are replaced, control the hand-held electric drill 2 to reverse, causing the connecting plate 1 to move downward on the bolt, while simultaneously moving the U-shaped frame 3 downward. The base support 4 on the U-shaped frame 3 separates from the bottom of the cable trolley, and the new cable trolley wheels abut against the I-beam, thus completing the replacement of the cable trolley wheels.

[0022] After replacement, remove pin 8 from U-shaped frame 3 to separate base 4 from U-shaped frame 3, and then remove the entire device from the I-beam.
