Description

Technical Field

[0001] This utility model relates to the field of crane technology, and in particular to a crane moving device that is easy to replace. Background Technology

[0002] Crane moving devices are a key component in ensuring the flexible operation of cranes. Common types include wheeled, tracked, and rail-mounted moving devices. Rail-mounted moving devices rely on rails for guidance and precise positioning. They are often used in large construction sites, factories, and other scenarios where high positioning accuracy is required. They enable cranes to move smoothly along a predetermined route, ensuring the safe and accurate handling of goods.

[0003] However, most crane mobile devices adopt an integrated design, which requires complete disassembly for maintenance. This operation is complex, time-consuming, and labor-intensive. Once a component is damaged, a large number of related structures may need to be disassembled for replacement, resulting in long downtime, affecting production progress, increasing operational risks, and raising maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where most crane moving devices adopt an integrated design, which requires the whole disassembly during maintenance, making the operation complicated, time-consuming and labor-intensive. Once a component is damaged, a large number of related structures may need to be disassembled to replace it, resulting in long downtime, affecting production progress, increasing operational risks and maintenance costs. Therefore, this utility model proposes a crane moving device that is easy to replace.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a crane moving device that is easy to replace, comprising a support column, a first guide rail, a second guide rail, a moving device, and a maintenance device. The first guide rail is fixedly connected to the support column, and there are two support columns arranged symmetrically. The second guide rail is located at one end of the first guide rail. The moving device is slidably connected to the surface of the first guide rail. The maintenance device is disposed on the surface of the second guide rail, and the maintenance device includes a rotating rod rotatably connected to the support column. One end of the second guide rail is fixedly connected to the rotating rod. The second guide rail is close to the first support column. A cavity is formed at one end of a guide rail, and an insert block is slidably connected to the inner wall of the cavity. A slot is formed at the end of the first guide rail near the insert block, and the insert block is inserted into the first guide rail. A motor is fixedly connected to the end of the support column near the rotating rod, and the drive end of the motor is fixedly connected to the rotating rod. By setting a maintenance device, pulling the ring drives the pull rope, causing the insert block to disengage from the first guide rail. Then, the motor drives the rotating rod to rotate, realizing the disconnection between the first guide rail and the second guide rail. This creates a sliding gap for the mobile device, reducing the disadvantages of the complex disassembly required when disassembling the traditional integrated structure, greatly shortening the disassembly time, and improving maintenance efficiency.

[0006] Preferably, one end of the insert is fixedly connected to a spring, and the end of the spring away from the insert is fixedly connected to the inner wall of the second guide rail. By setting the spring, the spring squeezes the insert with elastic force, so that it is tightly inserted into the slot of the first guide rail, ensuring that the first guide rail and the second guide rail form a firm rigid connection during normal operation, and preventing the guide rail from separating due to vibration or external force during the sliding of the mobile device.

[0007] Preferably, a pull rope is fixedly connected to one side of the insertion block. The end of the pull rope away from the insertion block passes through the second guide rail and is fixedly connected to a ring. By setting the pull rope, when the ring is pulled, the ring transmits the pulling force to the insertion block through the pull rope, overcomes the spring force, and pulls the insertion block out of the slot of the first guide rail, so that the connection between the first guide rail and the second guide rail is broken, creating conditions for the mobile device to slide out.

[0008] Preferably, a wheel is rotatably connected to one end of the support column near the pull rope, and the pull rope contacts the wheel.

[0009] Preferably, a positioning component is provided at one end of the rotating rod. The positioning component includes a circular block, which is fixedly connected to the end of the rotating rod away from the motor. A baffle is fixedly connected to the surface of the circular block. By setting the positioning component, when the rotating rod drives the second guide rail to reset, the baffle and the circular block rotate together until the baffle abuts against the assembly table. Using this as a reference point, the first guide rail and the second guide rail can be accurately aligned, reducing problems such as poor gliding, jamming, or even derailment of the mobile device caused by guide rail misalignment, and providing basic conditions for the subsequent normal gliding of the mobile device.

[0010] Preferably, an assembly table is fixedly connected to the side of the support column near the baffle. The assembly table is located on the lower surface of the baffle. By setting the baffle, when the rotating rod drives the second guide rail to reset, the baffle rotates with the rotating rod until it abuts against the assembly table. The physical limit ensures that the connection between the first guide rail and the second guide rail is accurately aligned, avoiding misalignment of the guide rail due to incomplete reset, which would affect the normal sliding of the mobile device.

[0011] Preferably, the assembly table is arranged in an "L" shape, and the baffle is in contact with the assembly table.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up a maintenance device, when the mobile device needs to be removed for maintenance, pulling the ring causes the ring to pull the rope, which pulls the plug block away from the first guide rail. Then, the motor is started, and the motor drives the rotating rod to rotate upward. At this time, the first guide rail and the second guide rail are disconnected, and the mobile device can slide out along the disconnected gap. After the mobile device is maintained, when the mobile device is re-attached to the first guide rail through the cross section, the motor is then started to drive the rotating rod to reset the second guide rail and release the ring. The rope is no longer restrained, and the spring generates elastic force to squeeze the plug block into the first guide rail, reconnecting the first guide rail and the second guide rail. The mobile device can then slide normally on the first and second guide rails. By setting up a maintenance device, pulling the ring causes the rope to pull the plug block away from the first guide rail, and then using the motor to drive the rotating rod to rotate, the first guide rail and the second guide rail are disconnected, thus creating a sliding gap for the mobile device. This reduces the disadvantages of the complex disassembly required for traditional integrated structures, greatly shortens the disassembly time, and improves maintenance efficiency.

[0014] 2. In this utility model, by setting a positioning component, when the rotating rod rotates to reset, the baffle and the round block follow the rotating rod to rotate until the baffle abuts against the assembly table, which facilitates the precise alignment of the first guide rail and the second guide rail. By setting a positioning component, when the rotating rod drives the second guide rail to reset, the baffle and the round block follow the rotation until the baffle abuts against the assembly table. Using this as a reference point, it is ensured that the first guide rail and the second guide rail can be precisely aligned, reducing problems such as poor gliding, jamming, or even derailment of the mobile device caused by guide rail misalignment, and providing basic conditions for the normal gliding of the mobile device in the future.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a crane moving device that is easy to replace, including a support column 1, a first guide rail 2, a second guide rail 3, a moving device 4, and a maintenance device 5. The first guide rail 2 is fixedly connected to the support column 1. There are two support columns 1, which are symmetrically arranged. The second guide rail 3 is located at one end of the first guide rail 2. The moving device 4 is slidably connected to the surface of the first guide rail 2. The maintenance device 5 is located on the surface of the second guide rail 3.

[0022] In this implementation scheme: the maintenance device 5 includes a rotating rod 58, which is rotatably connected to the support column 1. One end of the second guide rail 3 is fixedly connected to the rotating rod 58. A cavity 59 is opened at the end of the second guide rail 3 near the first guide rail 2. An insert block 51 is slidably connected to the inner wall of the cavity 59. A slot is opened at the end of the first guide rail 2 near the insert block 51, and the insert block 51 is inserted into the first guide rail 2. A motor 57 is fixedly connected at the end of the support column 1 near the rotating rod 58. The drive end of the motor 57 is fixedly connected to the rotating rod 58. By setting up the maintenance device 5, pulling the ring 55 drives the pull rope 53, causing the insert block 51 to disengage from the first guide rail 2. Then, the motor 57 drives the rotating rod 58 to rotate, thereby disconnecting the first guide rail 2 from the second guide rail 3. This creates a sliding gap for the mobile device 4, reducing the disadvantages of complex disassembly of the whole when disassembling the traditional integrated structure, greatly shortening the disassembly time, and improving maintenance efficiency.

[0023] Specifically, one end of the insert 51 is fixedly connected to a spring 52, and the end of the spring 52 away from the insert 51 is fixedly connected to the inner wall of the second guide rail 3. By setting the spring 52, the spring 52 squeezes the insert 51 with elastic force, so that it is tightly inserted into the slot of the first guide rail 2, ensuring that the first guide rail 2 and the second guide rail 3 form a firm rigid connection during normal operation, and preventing the guide rails from separating due to vibration or external force during the sliding of the mobile device 4.

[0024] Specifically, a pull rope 53 is fixedly connected to one side of the insertion block 51. The end of the pull rope 53 away from the insertion block 51 passes through the second guide rail 3 and is fixedly connected to a ring 55. By setting the pull rope 53, when the ring 55 is pulled, the ring 55 transmits the pulling force to the insertion block 51 through the pull rope 53, overcomes the elastic force of the spring 52, and pulls the insertion block 51 out of the slot of the first guide rail 2, so that the connection between the first guide rail 2 and the second guide rail 3 is broken, creating conditions for the mobile device 4 to slide out.

[0025] Specifically, a wheel 54 is rotatably connected to one end of the support column 1 near the pull rope 53, and the pull rope 53 contacts the wheel 54.

[0026] Specifically, a positioning component 56 is provided at one end of the rotating rod 58. The positioning component 56 includes a round block 561, which is fixedly connected to the end of the rotating rod 58 away from the motor 57. A baffle 562 is fixedly connected to the surface of the round block 561.

[0027] In this embodiment: by setting the positioning component 56, when the rotating rod 58 drives the second guide rail 3 to reset, the baffle 562 and the round block 561 rotate together until the baffle 562 abuts against the assembly table 563. Using this as a reference point, it is ensured that the first guide rail 2 and the second guide rail 3 can be accurately aligned, reducing problems such as the mobile device 4 not sliding smoothly, getting stuck or even derailing due to guide rail misalignment, and providing basic conditions for the subsequent normal sliding of the mobile device 4.

[0028] Specifically, an assembly table 563 is fixedly connected to the side of the support column 1 near the baffle 562, and the assembly table 563 is located on the lower surface of the baffle 562.

[0029] In this embodiment: by setting baffle 562, when the rotating rod 58 drives the second guide rail 3 to reset, baffle 562 rotates with the rotating rod 58 until it abuts against the assembly table 563. The physical limit ensures that the connection between the first guide rail 2 and the second guide rail 3 is accurately aligned, avoiding misalignment of the guide rail due to incomplete reset, which would affect the normal sliding of the mobile device 4.

[0030] Specifically, the assembly table 563 is arranged in an "L" shape, and the baffle 562 is in contact with the assembly table 563.

[0031] Working principle: By setting up maintenance device 5, when the mobile device 4 needs to be removed for maintenance, pull the ring 55. The ring 55 drives the pull rope 53, which pulls the insert block 51 away from the first guide rail 2. Then, start the motor 57, which drives the rotating rod 58 to rotate upward. At this time, the first guide rail 2 and the second guide rail 3 are disconnected, and the mobile device 4 can slide out along the disconnection gap. After the maintenance of the mobile device 4 is completed, when the mobile device 4 is re-attached to the first guide rail 2 through the cross-section, the motor 57 is then started to drive the rotating rod 58 to reset the second guide rail 3, and the ring 55 is released, and the pull rope 53 is disengaged. The spring 52 generates elastic force to squeeze the insert 51 into the first guide rail 2, reconnecting the first guide rail 2 with the second guide rail 3. The mobile device 4 can then slide normally on the first guide rail 2 and the second guide rail 3. By setting up the maintenance device 5, the ring 55 is pulled to drive the pull rope 53, causing the insert 51 to disengage from the first guide rail 2. Then, the motor 57 drives the rotating rod 58 to rotate, realizing the disconnection between the first guide rail 2 and the second guide rail 3. This creates a sliding gap for the mobile device 4, reducing the disadvantages of the traditional integrated structure that requires complex disassembly, greatly shortening the disassembly time and improving maintenance efficiency.

[0032] By setting the positioning component 56, when the rotating rod 58 rotates to reset, the baffle 562 and the round block 561 rotate with the rotating rod 58 until the baffle 562 abuts against the assembly table 563, which facilitates the precise alignment of the first guide rail 2 and the second guide rail 3. By setting the positioning component 56, when the rotating rod 58 drives the second guide rail 3 to reset, the baffle 562 and the round block 561 rotate with the rotating rod until the baffle 562 abuts against the assembly table 563. Using this as a reference point, it ensures that the first guide rail 2 and the second guide rail 3 can be precisely aligned, reducing problems such as the mobile device 4 not sliding smoothly, getting stuck, or even derailing due to guide rail misalignment, and providing basic conditions for the subsequent normal sliding of the mobile device 4.
