Description

Technical Field

[0001] The invention relates to the field of transportation, and in particular to a circular tube rail transportation hanging wheel. Background Art

[0002] Circular tube rail transportation is a commonly used method of transporting heavy objects in production. It uses a pre-erected circular tube track as a guide track, on which a hanging wheel that can move along the track is arranged. The heavy object is hoisted under the hanging wheel, and then the heavy object moves along the extension direction of the circular tube track with the hanging wheel, thereby achieving the transportation purpose.

[0003] During the laying process of the circular tube track, there are usually multiple turns according to the planning of the conveying path. When the hanging wheel carrying the heavy objects moves to the turning position, it is easy to separate from the circular tube track due to inertia, causing derailment. At the same time, the contact point between the hanging wheel and the circular tube track is a rotating wheel structure. The rotating wheel is pulled by the heavy objects under the hanging wheel, and the positive pressure between it and the circular tube track is large, so the rotating wheel structure is severely worn.

[0035] like Figures 1 to 4 As shown, an embodiment of the present invention provides a circular tube rail transport hanging wheel (hereinafter referred to as hanging wheel), including a hanging seat 200, a suspension structure 500, a rotating wheel mechanism 300 and an adjusting mechanism 400. A circular arc opening is opened in the center of the upper part of the hanging seat 200, and the diameter of the circular arc opening is larger than the outer diameter of the circular tube rail 100; the suspension structure 500 is rotatably arranged at the lower part of the hanging seat 200 for hanging heavy objects; the rotating wheel mechanism 300 has two and is respectively located on both sides of the circular arc opening at the top of the hanging seat 200, the rotating wheel mechanism 300 includes a supporting part 320 and a rotating wheel body 310, the supporting part 320 has two ends, the middle part of the supporting part 320 is hinged to the hanging seat 200 and can slide elastically left and right relative to the hanging seat 200, and the rotating wheel body 310 is rotatably arranged at one end of the supporting part 320.

[0036] The adjusting mechanism 400 is arranged on the hanging seat 200 and is located below the supporting part 320, and supports the end of the supporting part 320 away from the rotating wheel body 310 so that the rotating wheel body 310 abuts against the outer peripheral wall of the circular tube track 100. The adjusting mechanism 400 is configured to lift the end of the supporting part 320 away from the rotating wheel body 310 to rotate the supporting part 320 when the hanging wheel of the present invention reaches the turning point of the circular tube track 100, so as to lift the hanging seat 200, thereby lifting the overall center of gravity of the device, reducing the rotational inertia of the device when turning, and avoiding derailment of the device at the turning point.

[0037] To facilitate installation, the present invention provides a preferred embodiment, in which the hanging seat 200 includes two hanging plates 210, which are arranged at intervals and connected to each other; two hinged columns are arranged in the middle of the support portion 320, and horizontal slide grooves 211 are arranged on the two hanging plates 210. The support portion 320 is arranged between the two hanging plates 210 and the hinged columns are slidably arranged in the corresponding horizontal slide grooves 211, and elastic members 212 are arranged on both sides of the hinged columns in the horizontal slide groove 211, and the elastic members 212 make the hinged columns initially located in the middle of the horizontal slide groove 211; the elastic member 212 is preferably a compression spring.

[0038] It should be noted that the circular tube track 100 is a transport track erected using circular tubes in a workshop or on-site according to a pre-planned transport path. The hanging wheel of the present invention is installed on the circular tube track 100 and can move along the circular tube track 100. The heavy object is suspended on the suspension structure 500 of the hanging wheel. The hanging wheel can be driven to move along the circular tube track 100 by pushing the hung heavy object, or a driving motor is set on the rotating wheel body 310 of the hanging wheel to drive the rotating wheel body 310 to rotate, thereby realizing the movement of the device along the circular tube track 100; or when erecting the circular tube track 100, the circular tube track 100 can be made to have a certain inclination angle, so that the device can move along the circular tube track 100 by gravity. For example, when the device is used in a small workshop or construction site, it is mostly manually pushed to drive the hanging wheel to move along the circular tube track 100, and sometimes it is assisted by the inclination of the circular tube track 100. Technical personnel in this field can make an adaptive choice according to the size of the site or construction needs.

[0039] When the circular tube track 100 is erected, it usually turns according to the needs of the transportation path. When the hanging wheel moves along the circular tube track 100 to the turning point, it is easy to detach from the circular tube track 100 due to inertia, causing certain dangers. The present invention is to rotate the support part 320 on which the rotating wheel body 310 is installed to the hanging seat 200, and an adjustment mechanism 400 is provided to support and adjust the support part 320. When the hanging wheel moves to the turning point, the adjustment mechanism 400 pushes the end of the support part 320 away from the rotating wheel body 310, so that the support part 320 rotates in a direction close to the horizontal. During the rotation of the support part 320, the hanging seat 200 is lifted, so that the overall center of gravity of the device is lifted, the rotational inertia of the device when turning is reduced, and the device is prevented from derailing at the turning point.

[0040] In a further embodiment, the support part 320 includes a support cylinder 321 and a support shaft 322, the support cylinder 321 is hinged to the hanging plate 210 of the hanging seat 200, the support shaft 322 is slidably inserted in the support cylinder 321, the wheel body 310 is rotatably arranged on the support shaft 322 through the bearing 323, an oil storage cavity is formed between the bottom of the support cylinder 321 and the support shaft 322, the oil storage cavity is filled with lubricating oil, and an oil passage connecting the oil storage cavity and the bearing 323 is arranged on the support shaft 322. When the device reaches the turning point of the circular tube track 100, the adjustment mechanism 400 pushes the end of the support cylinder 321 away from the wheel body 310 to move upward, thereby rotating the support cylinder 321, and the support cylinder 321 drives the hanging seat 200 to rise, and at the same time, the support cylinder 321 approaches the support shaft 322, the oil storage cavity is compressed, and the lubricating oil in the oil storage cavity is squeezed to the bearing 323 to lubricate the bearing 323, thereby reducing the wear of the device and extending the service life.

[0041] In a further embodiment, the adjustment mechanism 400 includes two adjustment units, which are respectively arranged under the corresponding support tube 321 , and the adjustment unit includes a limiting sleeve 410 , a sliding sleeve 420 , a curved slide plate 430 and a push spring 440 .

[0042] The limiting sleeve 410 is fixedly arranged on the hanging seat 200 and tilted to point to the end of the support tube 321 away from the rotating wheel body 310; the sliding sleeve 420 is coaxially slidably sleeved on the outside of the limiting sleeve 410; the curved slide plate 430 is slidably inserted in the hanging seat 200 along the front-back direction and extends out of the hanging seat 200 at both ends. A reset structure is provided on the curved slide plate 430 for resetting the curved slide plate 430. The curved slide plate 430 is located below the sliding sleeve 420 and is aligned with the sliding sleeve 420. The sleeve 420 is vertical, and the surface (upper surface) of the curved slide plate 430 close to the sliding sleeve 420 is a concave curved surface that is concave downward; the curved slide plates 430 of the two adjustment units are connected so that the two curved slide plates 430 move synchronously; the push spring 440 is arranged inside the limiting sleeve 410, with the upper end connected to the support tube 321 and the lower end connected to the sliding sleeve 420, and the sliding sleeve 420 abuts against the curved slide plate 430 under the action of the push spring 440.

[0043] Specifically in this embodiment, a connecting pin 220 is fixedly provided between the two hanging plates 210, and there are two connecting pins 220. A guide ring 431 is fixedly provided on the lower surface of the curved skateboard 430, and the guide ring 431 is slidably sleeved on the connecting pin 220, so that the curved skateboard 430 can slide along the connecting pin 220; the reset structure is a spring telescopic rod 450, and spring telescopic rods 450 are provided on both sides of the guide ring 431 on the curved skateboard 430, and the end of the spring telescopic rod 450 away from the guide ring 431 is connected to the corresponding hanging plate 210, and the spring telescopic rod 450 makes the curved skateboard 430 initially in the middle position. When the hanging wheel reaches the turning point of the circular tube track 100, the front end of the curved slide plate 430 located on the inner side of the turning direction (the forward direction is forward) moves backward under the push of the turning circular tube track 100. Since the upper surface of the curved slide plate 430 is a concave curved surface, after the curved slide plate 430 slides, the bottom end of the sliding sleeve 420 contacts the higher part of the upper surface of the curved slide plate 430 and is then lifted up by the curved slide plate 430. The support tube 321 is pushed by the push compression spring 440 to achieve deflection.

[0044] Furthermore, in order to achieve the connection between the curved slides 430 of the two adjustment units, a connecting rod 460 is provided between the two curved slides 430 , and both ends of the connecting rod 460 are respectively connected to the guide ring 431 of one of the curved slides 430 .

[0045] In a further embodiment, a mounting tube 230 is fixedly disposed between the two hanging plates 210, and the hanging structure 500 is rotatably disposed on the mounting tube 230. The hanging structure 500 may be a structure such as a hanging ring used in the prior art, which will not be described in detail here.

[0046] The following takes the example of pushing a heavy object to make the hanging wheel move along the circular tube track 100 to illustrate the use principle and working process of the present invention:

[0047] A heavy object is hung on the hanging structure 500 , and then the heavy object is pushed to drive the hanging wheel to move forward along the circular tube track 100 .

[0048] Since the support of the hanging wheel and the heavy object depends on the pressure of the rotating wheel body 310 on the circular tube track 100, when hanging a heavy object, the support shaft 322 drives the support tube 321 to deflect relative to the hanging seat 200, compressing the push spring 440.

[0049] When the hanging wheel moves to the turning point, since the hanging plate 210 is exposed on both sides of the curved slide plate 430, the exposed part of the curved slide plate 430 located on the inner side of the turning direction is pushed by the turning circular tube track 100, and the curved slide plate 430 slides relative to the hanging plate 210. Since the bottom end of the sliding sleeve 420 is always against the upper surface of the curved slide plate 430 under the action of the pushing compression spring 440, after the curved slide plate 430 slides, the bottom end of the sliding sleeve 420 and the higher part of the upper surface of the curved slide plate 430 When the support tube 321 makes contact with the cylindrical body 310, the support tube 321 is pushed by the push spring 440 and deflected, tending to be more horizontal (the outer peripheral surface of the wheel body 310 is a spherical surface, so it can still roll relative to the circular tube track 100 after deflection), which increases the center of gravity of the device and reduces the moment of inertia, thereby preventing the device from derailing when turning. At the same time, after the support tube 321 is deflected, it approaches the support shaft 322, the oil storage chamber is compressed, and the lubricating oil in the oil storage chamber is squeezed out to lubricate the bearing 323, thereby preventing the device from wearing too quickly and extending its service life.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
