Detailed Description
In order to make the technical solutions of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. The specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
As shown in fig. 1, a belt cement clamping frame comprises a main bracket a and a sub-bracket B for clamping a belt and a locking and fixing device installed at the outer sides of the main bracket a and the sub-bracket B. The main bracket A and the auxiliary bracket B comprise an L-shaped clamping bracket 1 and a clamping device. The clamping device comprises a compression nut 2 and a compression bolt 3, wherein the compression nut 2 is installed on the inner side of the L-shaped clamping support 1, the compression bolt 3 is connected with the L-shaped clamping support 1 through the compression nut 2, and the belt is pressed and fixed on the L-shaped clamping support 1 by screwing in downwards. On one side, the belt crack is respectively fixed by the main support A and the auxiliary support B, the main support A and the auxiliary support B are fixed in a tensioning manner through the locking and fixing device arranged on the outer side of the L-shaped clamping support 1 of the main support A and the auxiliary support B, the stress at the crack is reduced, and when the belt crack is bonded, the belt joint can be stably and tightly attached. The locking and fixing device comprises a guide ring 7 arranged on the outer side of the L-shaped clamping support 1 of the main support, a tensioning nut 4 arranged on the outer side of the L-shaped clamping support 1 of the auxiliary support, a tensioning bolt 5 for connecting the guide ring 1 and the tensioning nut 4, and a locking nut 6 which is arranged on the inner side of the guide ring 7 and used for locking and fixing the tensioning bolt 5. The tension bolt 5 penetrates through one side of the guide ring 7, the locking nut 6 is arranged on the tension bolt 5 on the other side of the guide ring 7, the tension bolt 5 is screwed into the tension nut 4, the belt is tensioned by adjusting the tension bolt 5, and the tension bolt 5 is fixed by the locking nut 6.
As shown in fig. 2 and 3, the L-shaped holding brackets 1 of the primary bracket a and the secondary bracket B are made of angle iron, and are made of 40 × 40mm in this embodiment. The compression nut 2 is installed at the inner side of the L-shaped clamping support 1, preferably at the middle upper part of the inner side surface of the L-shaped clamping support 1, and the compression bolt 3 is screwed into the compression bolt 2 to be connected with the L-shaped clamping support 1, so that the belt is pressed down to be compressed and fixed. The guide ring 7 and the tensioning nut 4 are installed on the outer side of the L-shaped clamping support 1, the center of the through hole is located on the same horizontal straight line, and in order to enable the main support A and the auxiliary support B to be stressed evenly during tensioning, the main support A and the auxiliary support B are preferably installed in the middle of the outer side face of the L-shaped clamping support 1.
