Description

Technical Field

[0001] The utility model relates to the technical field of I-shaped wheel locking, in particular to an I-shaped wheel locking device for a turnover trolley. Background Art

[0002] The I-shaped wheel is a tool used to wind metal wire or wire rope. The specifications and materials of the I-shaped wheel vary according to the materials and specifications of the wire rope being wound. The I-shaped wheel for winding steel wire generally uses a steel plate structure, but wooden I-shaped wheels can be used for winding fine steel wire and non-ferrous metal wire. The use of plastic I-shaped wheels is increasing day by day. By placing the I-shaped wheel on a turnover trolley, it can be moved freely.

[0003] At present, the known I-wheel locking structure of the turnover trolley is an outer circle locking structure. By turning the brake handle, the brake arm installed on the frame is driven to rotate, so that the locking wheel made of polyurethane material installed at the front end of the brake arm moves, which is used to frictionally lock the outer circle of the I-wheel. In actual use, due to the elliptical shape of the outer circle of the I-wheel, the braking effect is not ideal, and some I-wheels cannot be locked. Therefore, there is an urgent need for a turnover trolley I-wheel locking device to solve the above problems. Utility Model Content

[0004] Based on the deficiencies in the prior art mentioned in the above background technology, the utility model provides a spool locking device for a turnover trolley.

[0006] A spool locking device for a turnover trolley comprises a frame, a material roll spool and a pad cloth spool are arranged on the top of the frame, and the material roll spool is located on the left side of the pad cloth spool;

[0007] The diameter of the material roll spool is larger than the diameter of the pad cloth spool;

[0008] A locking assembly for fixing the material roll spool is arranged on the top of the frame.

[0009] As a further solution of the utility model: the locking assembly includes a brake arm fixedly connected to the top outer wall of the frame, the top of the brake arm is provided with a first fisheye joint, the top of the frame is provided with a connecting rod, a movable rod is provided on one side of the first fisheye joint, and a second fisheye joint is provided on the end of the movable rod away from the first fisheye joint.

[0010] As a further solution of the utility model: a locking rod is arranged on one side of the brake arm, and a locking groove is opened on one side of the locking rod.

[0011] As a further solution of the utility model: the circumferential inner wall of the material roll I-shaped wheel is fixedly connected with a rotating shaft, and locking blocks are arranged at both ends of the rotating shaft, and the locking blocks cooperate with the locking grooves.

[0012] As a further solution of the utility model: a mounting frame is fixedly connected to the top of the frame, and a brake handle is provided on one side of the mounting frame.

[0013] As a further solution of the utility model: a vertical frame is fixedly connected to the top of the frame;

[0014] The vertical frame and the mounting frame are formed in one piece, an adjusting rod is arranged on one side of the vertical frame, and a tension spring is arranged on one end of the adjusting rod.

[0015] As a further solution of the utility model: a fixing plate is fixedly connected to the bottom of the frame;

[0016] The bottom of the fixed plate is rotatably connected to a mounting seat, and the inner walls on both sides of the mounting seat are rotatably connected to rollers;

[0017] The number of the rollers is four groups, and the four groups of rollers are respectively arranged at the four corners of the frame.

[0018] After adopting the above structure, the utility model has the following advantages compared with the prior art:

[0019] Two locking blocks are installed on the brake arm. When working, the brake handle is turned to control the rotation of the brake arm, so that the locking block and the tightening wheel installed on the I-shaped wheel interact with each other to perform locking. At the same time, the turnover trolley adopts a new locking structure, which changes the I-shaped wheel locking from outer circle locking to locking block structure. The braking effect is stable and can prevent the adhesion of rubber caused by the rotation of the I-shaped wheel due to poor braking effect, thus meeting people's usage needs.
