The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1 and fig. 2, according to the cable dragging bracket provided by this embodiment, on one hand, the cable dragging bracket can be used to support a cable to be dragged, and on the other hand, the cable can be more stable during dragging, and the friction force for dragging the cable can be reduced, so as to save labor. The cable dragging device comprises at least three support frames 100 which are arranged in a surrounding mode and fixedly connected, wherein a plurality of support frames 100 are fixedly surrounded to form frames through which cables penetrate, and the cables to be dragged penetrate through the frames to form support for the cables; in order to reduce the friction force of dragging the cable and stably install the whole bracket, the support frame 100 is provided with a rolling matching mechanism and a fixing mechanism; before use, each bracket needs to be fixed on the cable dragging line, the fixing mechanism provided by the embodiment comprises a fixing block 400 fixed at the joint of two adjacent supporting frames 100, and the fixing block 400 is provided with a fixing hole. The fixing block 400 can be brought into contact with the mounting surface, and the bracket can be fixed to the fixing hole by a fixing member such as a bolt. In addition, the rolling matching mechanism comprises a rotating sleeve 200 sleeved on at least one support frame 100, the rotating sleeve 200 is in rotating matching with the support frame 100 to enable the support frame 100 to rotate circumferentially, and a rolling bearing 500 positioned in the rotating sleeve 200 is further installed on the support frame 100; the rotating sleeve 200 can be in rotating fit with a corresponding support frame 100 through the rolling bearing 500, and the rotating friction of the rotating sleeve 200 can be reduced under the action of the rolling bearing 500; thus, when the cable is dragged and pulled, the rotating sleeve 200 rotatably arranged on the support frame 100 can be in running fit with the cable, so that the cable forms rolling friction with a contact surface thereof, the friction force for dragging the cable is reduced, and the effects of saving time and labor are achieved. After long-time use, the rotating sleeve 200 can be ensured to rotate flexibly by adding lubricating oil/lubricating grease between the rotating sleeve 200 and the supporting frame 100; because the outer layer of the cable is a rubber layer, in order to avoid abrasion of the outer layer of the cable, the outer peripheral surface of the rotating sleeve 200 is sleeved with a protective sleeve, and the surface of the protective sleeve is provided with anti-skid grains. The outer surface of the cable can be prevented from being abraded by the protective sleeve.

In the embodiment, as shown in fig. 1, preferably, three support frames 100 are fixed around the bracket to form a frame in a triangular arrangement, and a rotating sleeve 200 is rotatably mounted on one of the support frames 100, and in order to improve the structural firmness and the stability of the rotation of the rotating sleeve 200, each support frame 100 that is not rotatably engaged with the rotating sleeve 200 is an L-shaped angle iron. The angle steel is rectangular steel with two mutually perpendicular sides to form an angle shape, can form various different stress members according to different requirements of the structure, can also be used as a connecting piece between the members, has higher mechanical performance, and ensures the firmness of the bracket structure.

In addition, the support bracket 100 rotatably engaged with the rotating sleeve 200 is cylindrically arranged. The support frame 100, which is arranged in a cylindrical shape, can be coaxially and rotatably fitted with the rotating sleeve 200, and a rolling bearing 500 or the like can be mounted on the support frame 100.

In other embodiments, for cables with larger specifications, the rotating sleeves 200 may be mounted on a plurality of support frames 100 to form a multi-angle rolling support for the cables, for example, the rotating sleeves 200 are mounted on the support frames 100 in a triangular arrangement, so that the rotating sleeves 200 on the support frames 100 form rolling friction with the cables; for another example, the support frame 100 having a quadrilateral shape may be provided with three rotating sleeves 200 on three of the support frames 100, and the three rotating sleeves 200 form a U-shaped rolling support for the cable.

As shown in fig. 2, since the rolling bearings 500 are sleeved at two ends of the supporting frame 100, in order to improve the stability of the installation of the rolling bearings 500, the supporting frame 100 is provided with positioning shoulders 120 at two ends thereof for installing and fixing the bearings. Thus, the rolling bearings 500 installed at both ends of the support bracket 100 can abut against a corresponding one of the positioning shoulders 120, preventing the rolling bearings 500 from slipping.

In addition, in order to prevent the end of the rotating sleeve 200 from rubbing against the end of the supporting frame 100 when rotating, which results in abrasion, in this embodiment, the two ends of the supporting frame 100 are provided with the limiting rings 110 corresponding to the outer sides of the rotating sleeve 200, the supporting frame 100 is further provided with the thrust bearings 300, and the two ends of the thrust bearings 300 abut against the limiting rings 110 and the end surfaces of the rotating sleeve 200. Thus, the end surface of the rotating sleeve 200 can be in rolling fit with the limit ring 110 through the thrust bearing 300, and the rotating sleeve 200 is prevented from being laterally deviated when rotating.

As shown in fig. 1, in order to facilitate the installation and removal of the entire bracket, a handle 600 is provided on one of the support frames 100 which is not rotatably engaged with the rotating sleeve 200. The handle 600 can facilitate the installation or removal of the entire bracket while being easily handled by an operator.
