Description

Technical Field

[0001] This utility model relates to the field of lifting tools technology, specifically a guide wheel lifting device. Background Technology

[0002] In various industrial production and logistics handling scenarios, the lifting operation of idler wheels is crucial. Traditional methods of lifting idler wheels often rely on simple rope binding or general-purpose lifting tools. These methods have many drawbacks. In the early days, using ropes to directly bind the idler wheels for lifting was not only time-consuming and labor-intensive, but also easily caused wear and scratches on the surface of the idler wheels during the binding process, affecting the accuracy and service life of the idler wheels.

[0003] During use, the idler wheel spreader needs to clamp and transport the idler wheel. Existing spreaders can only clamp and fix the idler wheel on both sides, lacking support on both sides. This makes it easy for the idler wheel to shake during transportation, which may lead to collisions. Therefore, we need an idler wheel spreader. Utility Model Content

[0004] The purpose of this utility model is to provide a guide wheel lifting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide wheel lifting device, including a crossbeam, a motor fixedly installed on the side wall of the crossbeam, a bidirectional threaded rod fixedly connected to the output end of the motor, the bidirectional threaded rod being internally threadedly connected to a threaded block, and the bidirectional threaded rod being rotated by starting the motor, which causes the two threaded blocks to move towards the two clamps at the ends of the connecting block to clamp and fix the guide wheel in the middle, the threaded block being slidably connected to the inner wall of the crossbeam, the outer wall of the threaded block being fixedly connected to one end of the connecting block, and a clamp being fixedly installed on the other end of the connecting block, the clamp having a support mechanism inside;

[0006] The support mechanism includes:

[0007] A rotating rod, which is used to drive the bent plate to rotate;

[0008] A curved plate, which is used to support the guide wheel;

[0009] A torsion spring is used to drive the rotating rod to rotate and reset.

[0010] Preferably, a rotating rod is rotatably connected to the inner wall of the clamp, and a bent plate is fixedly installed on the outer wall of the rotating rod. By pressing the end of the bent plate with a guide wheel, the bent plate can rotate around the rotating rod. The outer wall of the rotating rod is fixedly connected to one end of a torsion spring, and the other end of the torsion spring is fixedly connected to the inner wall of the clamp.

[0011] Preferably, a fixed frame is fixedly installed on the outer wall of the bent plate. The bent plate can drive the circular roller inside the fixed frame to squeeze and support the guide wheel. The inner wall of the fixed frame is fixedly connected to one end of the bearing spring, and a slider is fixedly installed on the other end of the bearing spring. The slider is slidably connected to the inner wall of the fixed frame.

[0012] Preferably, a round rod is rotatably connected to the outer wall of the slider. Through the rotatable connection between the round rod and the slider, the round roller can rotate on the outer wall of the guide wheel. The round roller is fixedly installed on the outer wall of the round rod.

[0013] Preferably, a sleeve is fixedly installed on the outer wall of the round rod, and the sleeve has a slot, which is arranged in an array on the sleeve.

[0014] Preferably, a fixing rod is fixedly installed on the inner wall of the fixing frame, an arc-shaped plate is fixedly installed at the end of the fixing rod, and a locking block is fixedly installed on the outer wall of the arc-shaped plate. The arc-shaped plate drives the locking block on the outer wall to engage with the inside of the locking groove, so that the sleeve can no longer rotate the round rod.

[0015] Compared with the prior art, the present invention provides a guide wheel lifting device, which has the following beneficial effects:

[0016] 1. The guide wheel lifting device is squeezed at the end of the bent plate in the support mechanism, which can make the bent plate rotate around the rotating rod. The bent plate can drive the round roller inside the fixed frame to squeeze and support the guide wheel. Through the rotational connection between the round rod and the slider, the round roller can rotate on the outer wall of the guide wheel, which makes it easy for the clamp to adjust the position of the guide wheel.

[0017] 2. The guide wheel lifting device uses a circular roller to drive the sleeve on the outer wall of the circular rod to move into the interior of the fixed frame, thereby causing the locking block on the outer wall of the arc plate to engage with the interior of the locking groove. This prevents the sleeve from driving the circular rod to rotate, and consequently prevents the circular roller from rotating, thus preventing the guide wheel from becoming unstable during the support and clamping process.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a guide wheel lifting device, including a crossbeam 1, a motor 2 fixedly installed on the side wall of the crossbeam 1, a bidirectional threaded rod 3 fixedly connected to the output end of the motor 2, the bidirectional threaded rod 3 being internally threadedly connected to a threaded block 4, by starting the motor 2 to drive the bidirectional threaded rod 3 to rotate, which enables the two threaded blocks 4 to drive the two clamps 6 at the ends of the connecting block 5 to move towards each other to clamp and fix the guide wheel in the middle, the threaded block 4 being slidably connected to the inner wall of the crossbeam 1, the outer wall of the threaded block 4 being fixedly connected to one end of the connecting block 5, the other end of the connecting block 5 being fixedly installed with a clamp 6, and the clamp 6 having a support mechanism 7 inside.

[0024] In this embodiment, the clamp 6 is provided with a support mechanism 7. The end of the bent plate 72 in the support mechanism 7 is squeezed, which causes the bent plate 72 to rotate around the rotating rod 71. The bent plate 72 can drive the circular roller 78 inside the fixed frame 74 to squeeze and support the guide wheel. Through the rotational connection between the circular rod 77 and the slider 76, the circular roller 78 can rotate on the outer wall of the guide wheel, which makes it easy for the clamp 6 to adjust the position of the guide wheel. At the same time, the circular roller 78 drives the sleeve 79 on the outer wall of the circular rod 77 to move into the interior of the fixed frame 74, so that the locking block 713 on the outer wall of the arc plate 712 can be engaged into the interior of the locking groove 710, so that the sleeve 79 can no longer drive the circular rod 77 to rotate, and thus the circular roller 78 cannot rotate, preventing rotation during the support and clamping of the guide wheel, which would cause the guide wheel to become unstable.

[0025] The aforementioned support mechanism 7 includes a rotating rod 71, which is rotatably connected to the inner wall of the clamp 6. A bent plate 72 is fixedly installed on the outer wall of the rotating rod 71. By pressing the end of the bent plate 72 with a guide wheel, the bent plate 72 can rotate around the rotating rod 71. The outer wall of the rotating rod 71 is fixedly connected to one end of a torsion spring 73, and the other end of the torsion spring 73 is fixedly connected to the inner wall of the clamp 6. A fixed frame 74 is fixedly installed on the outer wall of the bent plate 72. The bent plate 72 can drive the circular roller 78 inside the fixed frame 74 to press and support the guide wheel. The inner wall of the fixed frame 74 is fixedly connected to one end of a bearing spring 75. A slider 76 is fixedly installed on the other end of the bearing spring 75. The slider 76 is slidably connected to the inner wall of the fixed frame 74. A circular rod 77 is rotatably connected to the outer wall of the slider 76. The rotatable connection between rod 77 and slider 76 allows the roller 78 to rotate on the outer wall of the guide wheel. The roller 78 is fixedly installed on the outer wall of rod 77, and a sleeve 79 is fixedly installed on the outer wall of rod 77. The sleeve 79 has a slot 710, which is arranged in an array. A fixing rod 711 is fixedly installed on the inner wall of fixing frame 74. An arc plate 712 is fixedly installed at the end of fixing rod 711. A locking block 713 is fixedly installed on the outer wall of arc plate 712. The locking block 713 on the outer wall of arc plate 712 engages with the slot 710, preventing the sleeve 79 from rotating the rod 77 and preventing the roller 78 from rotating. This prevents rotation during the support and clamping of the guide wheel, which could lead to instability of the guide wheel.

[0026] In this embodiment, the starting motor 2 drives the bidirectional threaded rod 3 to rotate, which in turn causes the two threaded blocks 4 to move towards the two clamps 6 at the ends of the connecting block 5, clamping and fixing the guide wheel in the middle. During the clamping process, the clamps 6 press the end of the bent plate 72 through the guide wheel, causing the bent plate 72 to rotate around the rotating rod 71. This causes the bent plate 72 to drive the circular roller 78 inside the fixed frame 74 to press and support the guide wheel. Simultaneously, through the rotational connection between the circular rod 77 and the slider 76, the circular roller 78 can... The guide wheel can rotate on the outer wall, which makes it easy for the clamp 6 to adjust the position of the guide wheel. Then, the guide wheel squeezes the circular roller 78, causing the circular roller 78 to drive the sleeve 79 on the outer wall of the circular rod 77 to move into the fixed frame 74. This causes the locking block 713 on the outer wall of the arc plate 712 to engage into the slot 710, preventing the sleeve 79 from driving the circular rod 77 to rotate. Consequently, the circular roller 78 cannot rotate, preventing rotation during the support and clamping of the guide wheel, which could lead to instability of the guide wheel.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
