Description

Technical field:

[0001] The utility model belongs to the technical field of tire transportation, and particularly relates to a transport tire clamping device, which is especially suitable for the transportation of giant engineering tires. Background technology:

[0002] After the full steel radial tire is vulcanized, it is necessary to inspect the internal steel wire arrangement and other conditions, and use X-rays for flaw detection. Before the inspection, the finished tire needs to be forked onto the inspection and transport trolley by a forklift, and then the trolley is used to transport the tire to the designated location for inspection. Because the tire diameter is as large as 4 meters, if the placement deviation is large, it is possible to overturn, which not only poses a safety hazard, but may also cause damage to the equipment.

[0003] How to provide a more reasonable technical solution becomes the research object of the present invention. Summary of the invention:

[0004] The utility model aims to design a transport tire clamping device which is suitable for being placed on a trolley bucket and used for clamping tires.

[0005] The technical solution of the utility model is implemented as follows: a carrier tire clamping device, characterized in that it includes two symmetrically arranged wedge blocks, the surfaces facing each other of the two wedge blocks have an arc surface that matches the tire tread, a pair of clamping arms that can move laterally are arranged at a high position of the arc surface, and at least one clamping arm can clamp or release the surfaces on both sides of the tire when driven by a driving cylinder.

[0006] The wedge block is welded from steel plates, and includes an arc surface and a triangular rib plate supporting the arc surface. There are at least two triangular rib plates, which are respectively welded on both sides of the arc surface, and are supported on the trolley bucket by means of the triangular rib plates. A pair of slide grooves are respectively opened in the transverse direction of the arc surface, and one end of the clamping arm is slidably placed in the slide grooves. A guide rod parallel to the slide groove is also locked between the triangular rib plates. The guide rod passes through the through hole of the clamping arm and together with the slide groove forms a support and constraint for the clamping arm. One end of the driving cylinder arranged parallel to the guide rod is fixed on the triangular rib plate, and the other end is locked on the clamping arm.

[0007] The triangular rib plate is composed of three pieces, the middle piece is welded in the middle of the arc surface and also supports the middle of the guide rod; the facing surfaces of a pair of clamping arms are processed into curved surfaces that match the tire contour.

[0008] The driving cylinder is an air cylinder or an oil cylinder, and the air pressure or oil pressure is provided by the same pressure source, and the two driving cylinders between the same sides of the two wedge blocks are synchronously controlled and adjusted.

[0009] The utility model provides a clamp for a trolley carrying giant engineering tires, which has the characteristics of reasonable design, simple operation, convenient use and stable clamping; it can prevent the tire from rolling and form a clamp to prevent tilting, eliminating safety hazards in the transportation process.

[0021] Reference Figures 1 to 4 The carrier tire clamping device comprises two symmetrically arranged wedge blocks 1, the surfaces facing each other of the two wedge blocks 1 have arc surfaces 11 matching the tire tread, a pair of clamping arms 2 capable of laterally moving are arranged at the high position of the arc surfaces 11, at least one clamping arm 2 can clamp or release the surfaces on both sides of the tire 5 when driven by a driving cylinder 3; the arc surfaces 11 of the two wedge blocks prevent the tire from rolling, and the two clamping arms 2 clamp on both sides of the tire to keep the tire upright and stable and prevent it from tilting.

[0022] More specifically, the wedge block 1 is welded from steel plates, including an arc surface 11 and a triangular rib plate 12 supporting the arc surface. The triangular rib plate 12 has at least two pieces, which are welded on both sides of the arc surface 11 respectively. In this example, there are three pieces, and another piece is welded in the middle to support the middle part of the arc surface 11, which also strengthens the important part of the tire. With the help of the triangular rib plate 12, it is supported on the truck bed and is suitable for transportation in any truck bed.

[0023] A pair of slide grooves 13 are respectively provided in the transverse direction of the arc surface 11, and a guide rod 4 parallel to the slide groove is locked between the triangular rib plate 12, and the slide groove 13 and the guide rod 4 are used together to form a sliding support and constraint function for the clamping arm 2; the specific structure is that a through hole 21 for the guide rod 4 to pass through is provided at one end of the clamping arm 2, and this end is slidably placed in the slide groove 13 at the same time, and the other end is a suspended end for clamping the side of the tire. For this reason, the facing surfaces of the pair of clamping arms 2 are processed into a curved surface 22 that matches the contour of the tire 5, which can better match the side surface of the tire to increase the contact surface.

[0024] In addition, the driving cylinder 3 is arranged parallel to the guide rod 4, one end of which is fixed on the triangular rib plate 12 and the other end is locked on the clamping arm 2. The driving cylinder 3 is used to drive the clamping arm 2 to clamp or release the tire. In theory, only one clamping arm 2 on a wedge block 1 is required to be slidable, and the other clamping arm is fixed, so that a clamping action can also be formed. However, for a heavy engineering tire, it is difficult to use the driving cylinder to push the tire to move. The wedge block 1 can only be adjusted in the opposite direction to cater to the upright tire 5. For this reason, both clamping arms 2 are provided with driving cylinders 3, and it is most ideal to drive them to slide.

[0025] The driving cylinder 3 is an air cylinder or an oil cylinder, and the air pressure or oil pressure is provided by the same pressure source. The two driving cylinders 3 between the same side of the two wedge blocks 1 are synchronously controlled and adjusted, so that the synchronous adjustment of one side of the tire 5 can be realized.
