Description

Technical Field

[0001] This utility model relates to the technical field of tire production, and in particular to a retaining device for the bead of an engineering tire. Background Technology

[0002] After the engineering tire is formed, it needs to be stored on the tire blank storage vehicle for a period of time. However, because the bead part of the engineering tire is relatively heavy, the bead of the engineering tire may deform and sink during the storage process, which seriously affects the quality of the finished engineering tire. Therefore, it is necessary to design a bead retaining device for engineering tires to keep the bead of the engineering tire from deforming.

[0003] Existing engineering tire bead holding devices are hoisting type. After the engineering tire is formed, it is transferred to the area below the holding device, which then supports and holds the bead portion of the tire. These existing devices are bulky and require fixing in a specific area, occupying a significant amount of space and hindering the transport of the engineering tire. Delayed transport can also cause the bead portion of the tire to sink and deform, thus affecting the effectiveness of holding the bead. Utility Model Content

[0004] The present invention aims to provide a retaining device for the bead of an engineering tire, which occupies less space, keeps the bead of the engineering tire from deforming, facilitates the timely transfer of the engineering tire, and improves the retaining effect of the bead on the engineering tire.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a retaining device for engineering tire mouth, including a handwheel, a screw, a lifting ring, and a retaining mechanism. The handwheel is fixedly installed on the top of the screw, the retaining mechanism is installed on the screw, and the lifting ring is rotatably installed on the top of the handwheel. The screw has opposite thread directions at the top and bottom. The retaining mechanism includes two retaining components respectively arranged at the top and bottom of the screw, and the two retaining components are symmetrically arranged. Each retaining component includes a bushing, a connecting sleeve, a nut disc, and multiple retaining parts evenly spaced around the screw. Each retaining part includes a support frame, a connecting rod, a support claw, a long rod, a first short rod, a second short rod, and a rotating frame. The bushing and the nut disc are threadedly connected to the screw. The connecting sleeve is rotatably connected to the bushing. The support frame is fixedly installed on the connecting sleeve. One end of the connecting rod is installed on the support frame, and the other end is rotatably installed on the support claw. One end of the first short rod and the second short rod are rotatably installed on the connecting sleeve and the nut disc, respectively, and the other ends are rotatably installed on the rotating frame. One end of the long rod is rotatably installed on the support claw, and the other end is fixedly installed on the rotating frame.

[0006] As a preferred embodiment of the above solution, it also includes an adjusting block. The support frame has two sliding grooves and a fixing block is fixedly installed thereon. The fixing block has a through hole, and two locking bolts pass through the sliding grooves. The locking bolts are threaded to the adjusting block. The heads of the adjusting block and the locking bolts abut against both ends of the support frame, thereby positioning the adjusting block. One end of the connecting rod is fixedly connected to the adjusting block and passes through the through hole, thereby forming the connection between the connecting rod and the support frame.

[0007] More preferably, a graphite copper sleeve is fixedly installed on the connecting rod, and the graphite copper sleeve is slidably disposed in the through hole.

[0008] More preferably, the bushing is located inside the connecting sleeve, and is rotatably connected to the connecting sleeve by two deep groove ball bearings and a thrust bearing.

[0009] More preferably, an elastic retainer for holes is fixedly installed inside the connecting sleeve, and the two deep groove ball bearings are located between the thrust bearing and the elastic retainer for holes, thereby achieving axial limiting of the deep groove ball bearings and preventing the deep groove ball bearings from axially loosening and falling off.

[0010] More preferably, the support claw includes an arc-shaped plate and a connecting frame, the arc-shaped plate is fixedly installed on the connecting frame, and the long rod and connecting rod are rotatably installed on the connecting frame.

[0011] The beneficial effects of this utility model are:

[0012] 1. This invention utilizes a handwheel, screw, lifting ring, and two symmetrically arranged retaining components on the screw to support and retain the bezel portion of the engineering tire inside the tire, preventing deformation of the bezel and tire body. This invention is small in size, occupies little space, and does not require fixation in a specific area during use. This invention can be transported along with the engineering tire, thus facilitating timely transport while maintaining the bezel's integrity and improving the bezel's retention effect. By eliminating quality risks such as severe bezel sagging and deformation and tire body deformation during storage, this invention prevents defects in the finished engineering tire, such as internal air bubbles, insufficient glue, and tire body air bubbles, thus improving the performance of the finished engineering tire.

[0013] 2. This utility model uses a long rod, a first short rod, and a second short rod to enable the rotation of the support claw, which facilitates the support claw to fit into and move away from the opening part of the engineering tire. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-6 As shown, a retaining device for an engineering tire mouth includes a handwheel 2, a screw 4, a lifting ring 3, and a retaining mechanism. The handwheel 2 is fixedly installed on the top of the screw 4, the retaining mechanism is installed on the screw 4, and the lifting ring 3 is rotatably installed on the top of the handwheel 2. The screw 4 has an upper thread direction opposite to the lower thread direction. The retaining mechanism includes two retaining components respectively disposed on the upper and lower parts of the screw 4, and the two retaining components are symmetrically arranged.

[0022] The retaining assembly includes a bushing 19, a connecting sleeve 11, a nut disc 9, and multiple retaining parts evenly spaced around the screw 4. Each retaining part includes a support frame 5, a connecting rod 13, a support claw 1, a long rod 7, a first short rod 6, a second short rod 8, and a rotating frame 12. The bushing 19 and the nut disc 9 are both threadedly connected to the screw 4. The connecting sleeve 11 is rotatably connected to the bushing 19. The support frame 5 is fixedly mounted on the connecting sleeve 11. One end of the connecting rod 13 is mounted on the support frame 5, and the other end is rotatably mounted on the support claw 1. One end of the first short rod 6 and the second short rod 8 are rotatably mounted on the connecting sleeve 11 and the nut disc 9, respectively, and the other ends are rotatably mounted on the rotating frame 12. One end of the long rod 7 is rotatably mounted on the support claw 1, and the other end is fixedly mounted on the rotating frame 12.

[0023] After the engineering tire is formed, the lifting hook of the crane device is used to hook the lifting ring 3 to lift the present invention into the engineering tire. Then, the handwheel 2 is turned while the support frame 5 is kept stationary. The handwheel 2 will rotate together with the screw 4 and the bushing 19. The two nut discs 9 will move on the screw 4 and approach the corresponding connecting sleeve 11. The second short rod 8 will push the support claw 1 to rotate through the first short rod 6, the rotating frame 12 and the long rod 7 until the support claws 1 of the two retaining components respectively fit into the upper and lower bezels of the engineering tire, thereby forming a retaining effect on the upper bezel of the engineering tire. Then, the lifting hook of the crane device is separated and the crane device is removed. After hooking the lifting ring 3 with the hook of the crane device again, turn the handwheel 2 in the opposite direction and keep the support frame 5 stationary. The handwheel 2 will rotate together with the screw 4 and the bushing 19. The two nut discs 9 will move on the screw 4 and move away from the corresponding connecting sleeve 11. The second short rod 8 will push the support claw 1 to rotate through the first short rod 6, the rotating frame 12 and the long rod 7 until the support claws 1 of the two retaining components are away from the upper and lower openings of the engineering tire. The present invention can then be lifted and removed from the engineering tire. The number of retaining parts of one retaining component can be four.

[0024] It also includes an adjusting block 14. The support frame 5 has two sliding grooves 15 and a fixing block 10 is fixedly installed thereon. The fixing block 10 has a through hole. Two locking bolts (not shown in the figure) pass through the sliding grooves 15. The locking bolts are threaded to the adjusting block 14. The heads of the adjusting block 14 and the locking bolts abut against the two ends of the support frame 5 respectively, thereby positioning the adjusting block 14. One end of the connecting rod 13 is fixedly connected to the adjusting block 14 and passes through the through hole, thereby forming the connection between the connecting rod 13 and the support frame 5.

[0025] Rotate the locking bolt, and the locking bolt and adjusting block 14 will rotate relative to each other. The head of the locking bolt will move away from the adjusting block 14 and will no longer abut against the support frame 5. Then move the adjusting block 14. The adjusting block 14 will move together with the locking bolt and the connecting rod 13. The connecting rod 13 will move together with the support claw 1. The locking bolt will slide in the slide groove 15 until the support claw 1 moves to the predetermined position. Then rotate the locking bolt in the opposite direction. The head of the locking bolt will approach the adjusting block 14 and abut against both ends of the support frame 5, thereby positioning the adjusting block 14.

[0026] A graphite copper sleeve 18 is fixedly installed on the connecting rod 13, and the graphite copper sleeve 18 is slidably disposed in the through hole.

[0027] The graphite copper sleeve 18 can prevent the connecting rod 13 from directly contacting the inner wall of the through hole, thereby preventing wear on the connecting rod 13.

[0028] The bushing 19 is located inside the connecting sleeve 11 and is rotatably connected to the connecting sleeve 11 via two deep groove ball bearings 21 and a thrust bearing 22. A perforated elastic retainer 20 is fixedly installed inside the connecting sleeve 11, and the two deep groove ball bearings 21 are located between the thrust bearing 22 and the perforated elastic retainer 20, thereby axially limiting the deep groove ball bearings 21 and preventing the deep groove ball bearings 21 from axially loosening and falling off.

[0029] The deep groove ball bearing 21 and the thrust bearing 22 can avoid frictional losses caused by direct rotational contact between the bushing 19 and the connecting sleeve 11, and the elastic retainer 20 for the hole can be a snap ring.

[0030] The support claw 1 includes an arc-shaped plate 16 and a connecting frame 17. The arc-shaped plate 16 is fixedly installed on the connecting frame 17, and the long rod 7 and the connecting rod 13 are rotatably installed on the connecting frame 17.

[0031] The arc-shaped plate 16 facilitates the fit between the support claw 1 and the opening of the engineering jig, thereby better supporting and maintaining the opening of the engineering jig and preventing deformation of the opening.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
