[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. It is also known as an overhead crane, gantry crane, or hoist. The support roller is an important supporting component of the crane. The support roller needs to be frequently maintained and repaired, and it is necessary to disassemble the support roller.

[0003] Currently, most disassembly and assembly methods involve removing the track under the track roller, then flipping the entire track roller assembly over for disassembly and assembly. This method requires the use of specialized disassembly tools to operate on the track rollers one by one, and is time-consuming, labor-intensive, and results in low efficiency in disassembly and assembly of track rollers.

[0004] Therefore, a track support roller that is easy to disassemble and maintain is proposed here. Utility Model Content

[0005] This utility model proposes a track support roller that is easy to disassemble and maintain. It can drive multiple support rollers to move simultaneously using a transmission frame, thereby facilitating the inspection and replacement of the support rollers. It can also fix the position of the support rod, thereby increasing the stability of the support rollers in use.

[0006] This utility model is achieved through the following technical solution: a track support roller that is easy to disassemble and maintain, including a connecting frame, a transmission frame sliding inside the connecting frame, and a set of support components for supporting the connecting frame on both sides of the transmission frame. The support component includes a support shaft fixed to one side of the connecting frame, a support rod rotatably sleeved around the support shaft, a ball bearing fixedly sleeved at the end of the support rod away from the connecting frame, and a support wheel installed around the ball bearing.

[0007] Furthermore, a movable rod is fixedly sleeved at the end of the support rod away from the support wheel, and a set of sliding grooves are opened on one side of the transmission frame, with the movable rod sliding inside the sliding grooves.

[0008] Furthermore, the top surface of the connecting frame is provided with a power component that drives the transmission frame to move. The power component includes a motor fixed to the top surface of the connecting frame. The output end of the motor is fixed with a first threaded rod. A positioning block fixed to the upper surface of the connecting frame is rotatably sleeved around the first threaded rod. A transmission block is threadedly sleeved around the first threaded rod, and the transmission block is fixed to one side of the transmission frame.

[0009] Furthermore, the top surface of the connecting frame is provided with a moving groove, and the transmission block is slidably connected inside the moving groove.

[0010] The connecting frame is internally equipped with a limiting component for fixing the position of the support rod. The limiting component includes a support frame fixed to the inner top wall of the connecting frame. A set of positioning rods is fixed to the side of the support frame away from the connecting frame. A transmission sleeve is fixed to one side of one of the positioning rods. A second threaded rod is rotatably sleeved inside the transmission sleeve. Both ends of the second threaded rod are threaded with movable sleeves. A transmission rod is rotatably connected to both sides of the movable sleeve. A connecting plate is rotatably connected to the end of the transmission rod away from the movable sleeve. A set of connecting sleeves is fixed to the side of the connecting plate near the connecting frame. Two clamping rods are fixed to one side of the connecting sleeves.

[0011] Furthermore, the two ends of the second threaded rod are provided with two threads in opposite directions, and a transmission wheel is fixedly sleeved on one end of the second threaded rod.

[0012] Furthermore, the distance between the support frame and the connecting frame is greater than the height of the transmission frame, and the transmission frame slides between the support frame and the connecting frame.

[0013] This utility model provides a track support roller that is easy to disassemble and maintain, and its beneficial effects are as follows: This track support roller, which is easy to disassemble and maintain, moves by starting the motor to move the transmission frame. The transmission frame and the slide rail move the moving rod, which in turn moves the support rod to move the support wheel. When the support wheel contacts the track surface, it can support the connecting frame. Starting the motor in the opposite direction can move the support wheel to the side away from the track, thus facilitating the inspection and replacement of the support wheel.

[0014] This easily disassembled and maintained track support roller features a rotating drive wheel that moves the connecting plate via a second threaded rod. This causes the connecting sleeve to slide around the positioning rod and moves the two clamping rods to the periphery of the support rod, thus fixing the position of the support rod and increasing the stability of the support roller.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0018] Please see Figures 1-4 The present invention proposes the following implementation scheme: a track support roller that is easy to disassemble and maintain, including a connecting frame 1, a transmission frame 2 sliding inside the connecting frame 1, and a set of support components 4 for supporting the connecting frame 1 on both sides of the transmission frame 2. The support component 4 includes a support shaft 41 fixed to one side of the connecting frame 1, a support rod 42 rotatably sleeved around the support shaft 41, a ball bearing 43 fixedly sleeved at the end of the support rod 42 away from the connecting frame 1, and a support wheel 44 installed around the ball bearing 43.

[0019] Please refer to this carefully. Figure 3 The end of the support rod 42 away from the support wheel 44 is fixedly sleeved with a movable rod 45. A set of sliding grooves 21 are opened on one side of the transmission frame 2, and the movable rod 45 slides inside the sliding grooves 21.

[0020] In the above scheme, the transmission frame 2 and the slide 21 drive the moving rod 45 to move, so that the support rod 42 rotates around the support shaft 41 and drives the support wheel 44 to move together. When the support wheel 44 contacts the track surface, it can support the connecting frame 1. The reverse start motor 31 can move the support wheel 44 to the side away from the track, so as to facilitate the maintenance and replacement of the support wheel 44.

[0021] Please refer to this carefully. Figure 2The top surface of the connecting frame 1 is provided with a power component 3 that drives the transmission frame 2 to move. The power component 3 includes a motor 31 fixed on the top surface of the connecting frame 1. The output end of the motor 31 is fixed with a first threaded rod 32. The periphery of the first threaded rod 32 is rotatably sleeved with a positioning block 34 fixed on the upper surface of the connecting frame 1. The periphery of the first threaded rod 32 is threadedly sleeved with a transmission block 33, and the transmission block 33 is fixed on one side of the transmission frame 2.

[0022] The top surface of the connecting frame 1 is provided with a moving groove 11, and the transmission block 33 is slidably connected inside the moving groove 11.

[0023] In the above scheme, the starting motor 31 drives the first threaded rod 32 to rotate, and drives the transmission frame 2 to slide inside the connecting frame 1 through the transmission block 33.

[0024] Please refer to this carefully. Figure 2 and Figure 4 The connecting frame 1 is equipped with a limiting component 5 for fixing the position of the support rod 42. The limiting component 5 includes a support frame 51 fixed to the inner top wall of the connecting frame 1. A set of positioning rods 52 is fixed to the side of the support frame 51 away from the connecting frame 1. A transmission sleeve 53 is fixed to one side of one of the positioning rods 52. A second threaded rod 54 is rotatably sleeved inside the transmission sleeve 53. Both ends of the second threaded rod 54 are threadedly sleeved with movable sleeves 55. A transmission rod 56 is rotatably connected to both sides of the movable sleeve 55. A connecting plate 57 is rotatably connected to the end of the transmission rod 56 away from the movable sleeve 55. A set of connecting sleeves 58 is fixed to the side of the connecting plate 57 close to the connecting frame 1. Two clamping rods 59 are fixed to one side of the connecting sleeves 58. The distance between the two clamping rods 59 is greater than the width of the outer surface of the support rod 42.

[0025] Please refer to this carefully. Figure 4 The two ends of the second threaded rod 54 are provided with two threads in opposite directions, and a transmission wheel 541 is fixedly sleeved on one end of the second threaded rod 54.

[0026] The distance between the support frame 51 and the connecting frame 1 is greater than the height of the transmission frame 2, and the transmission frame 2 slides between the support frame 51 and the connecting frame 1.

[0027] In the above scheme, the rotating transmission wheel 541 drives the two movable sleeves 55 to move through the second threaded rod 54. The cooperation between the movable sleeves 55 and the transmission rod 56 drives the connecting plate 57 to move, so that the connecting sleeve 58 slides on the periphery of the positioning rod 52, and the two clamping rods 59 move to the periphery of the support rod 42.

[0028] In use, this invention works as follows: An external jack lifts the connecting frame 1, and the motor 31 drives the first threaded rod 32 to rotate. This, in turn, drives the transmission frame 2 to slide inside the connecting frame 1 via the transmission block 33. The transmission frame 2 and the sliding groove 21 then move the moving rod 45, causing the support rod 42 to rotate around the support shaft 41 and move the support wheel 44. When the support wheel 44 contacts the track surface, it supports the connecting frame 1. Reversing the motor 31 moves the support wheel 44 to a side away from the track, facilitating its inspection and replacement. Subsequently, the transmission wheel 541 rotates, and the second threaded rod 54 drives the two moving sleeves 55 to move. The cooperation between the moving sleeves 55 and the transmission rod 56 moves the connecting plate 57, causing the connecting sleeve 58 to slide around the positioning rod 52. This moves the two clamping rods 59 to the periphery of the support rod 42, fixing its position and increasing the stability of the support wheel 44.
