Technical Field

[0001] The utility model relates to an adjustable tire rotating clamp suitable for narrow space operations, belonging to the technical field of tire rotating clamps. Background Art

[0002] The tire rotating clamp is a commonly used machine tool for operations such as installation, placement, and transportation of tires.

[0003] At present, most of the common tire rotating clamps on the market have the following problems:

[0004] 1. The clamping part of the tire clamp cannot adjust the angle of the clamping plate. Therefore, when the clamp is clamping a tire with a smaller diameter, the clamping part and the tire are not in surface contact, which will cause certain dangers during the transportation of the loader.

[0005] 2. The clamping part at the front end of the clamp has a small adjustment range, which makes it impossible for the clamp to extend into some narrow spaces to perform work tasks, thereby greatly reducing the working capacity of the loader. Summary of the invention

[0006] The utility model aims to provide a tire rotating clamp with a narrow front clamping mechanism and adjustable clamping angle, thereby reducing the danger in the transportation process and improving the working capacity.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0016] The threaded rod is composed of a rod portion and a circular ring portion welded or integrally formed, the circular ring portion is hinged on a fixed shaft located on the boom beam, and the rod portion is provided with an external thread, which penetrates into the rotating shaft of the forward clamping mechanism;

[0017] A plurality of nuts are respectively arranged on the threaded rods located on both sides of the rotating shaft, and the purpose of adjusting the forward extending clamping mechanism is achieved by adjusting the tightening length of the nuts.

[0018] In some embodiments, the rotating device comprises:

[0019] An articulated bracket, the two arm beams are connected to the articulated bracket, the oil cylinder is arranged transversely in the articulated bracket, and the two ends of the oil cylinder are respectively articulated with the two arm beams; when the oil cylinder is retracted, the two arm beams are opened; when the oil cylinder is extended, the two arm beams are clamped;

[0020] A vertical rotary drive mechanism is mounted on the bracket, and the articulated bracket is rigidly connected to the vertical rotary drive mechanism;

[0021] The motor is installed on the bracket and is used to drive the vertical rotary drive mechanism to work, thereby driving the articulated bracket to rotate 360 ​​degrees.

[0022] In some embodiments, the forward clamping mechanism comprises:

[0023] A connecting frame, hinged on the arm beam and connected to the adjusting rod mechanism;

[0024] The clamping plates are rigidly connected to the connecting frame, and the tire is clamped by the clamping plates on both sides.

[0027] A plurality of connecting plates, one end of each connecting plate is fixed on the round rod, and the other end of each connecting plate is fixed on the back of the clamping plate, wherein at least one connecting plate continues to extend outward from the round rod to form a protrusion, and a rotating shaft for connecting to the adjusting rod mechanism is installed on the protrusion.

[0028] In some embodiments, at least one vertically arranged rib plate is fixed to the back side of the clamping plate, and the rib plate is fixed together with each connecting plate.

[0029] In some embodiments, the clamping plate is assembled with a nylon rubber plate whose size is not smaller than the clamping plate through a plurality of fasteners at the front side contacting the tire.

[0050] In this embodiment, three nuts 8.2 are provided, one nut 8.2 is provided on the outer side of the threaded rod 8.1, and two nuts 8.2 are provided on the inner side of the threaded rod 8.1.

[0051] like Figure 1 As shown, the slewing device includes an articulated bracket 6 and a vertical slewing drive mechanism 3; the arm beams I4 and II7 are connected to the articulated bracket 6, the cylinder is arranged horizontally in the articulated bracket 6, and the two ends of the cylinder are respectively articulated with the arm beams I4 and II7; when the cylinder retracts, the arm beams I4 and II7 are opened; when the cylinder extends, the arm beams I4 and II7 are clamped; the vertical slewing drive mechanism 3 is installed on the bracket 2, and the articulated bracket 6 is rigidly connected to the vertical slewing drive mechanism 3; the motor 1 is installed on the bracket 2, and is used to drive the vertical slewing drive mechanism 3 to work, and then drive the articulated bracket 6 to rotate 360 ​​degrees.

[0052] like Figure 2 As shown, the forward clamping mechanism 5 includes a connecting frame 5.1 and a clamping plate. The connecting frame 5.1 is hinged on the boom beam and connected to the adjusting rod mechanism 8. The clamping plate is rigidly connected to the connecting frame 5.1, and the tire is clamped by the clamping plates on both sides. At the same time, the entire clamping plate has a small thickness and a large width. When the tire is in a very narrow space, the clamping plate assembly can easily extend into it to clamp the tire.

[0053] Further solutions, such as Figure 2 As shown, the connecting frame 5.1 includes a vertically arranged round rod and a plurality of connecting plates; the top end of the round rod is inserted into the upper round tube of the boom beam, and the bottom end is inserted into the lower round tube of the boom beam, and the round rod and the round tube are gap-matched; one end of each connecting plate is fixed on the round rod, and the other end of each connecting plate is fixed on the back of the clamping plate, wherein at least one connecting plate continues to extend outward from the round rod to form a protrusion, and a rotating shaft for connecting to the adjusting rod mechanism 8 is installed on the protrusion.
