Description

Technical Field

[0001] This utility model relates to the field of cable fixing bracket technology, and in particular to tower crane cable fixing bracket. Background Technology

[0002] my country's construction engineering sector is booming, and tower cranes, as power transmission and control cables, have played a significant role in its development. For most high-rise and super high-rise buildings, the method for fixing tower crane cables involves welding a horizontal square steel section onto the tower crane connecting column, or drilling holes in the connecting column and installing bolts to attach a horizontal square steel section with an insulating porcelain insulator attached to it. The cable is then tied and fixed to this insulated porcelain insulator. However, welding or drilling at high altitudes is difficult. Therefore, one end of a support frame can be connected to the tower crane connecting column, and the cable can be fixed through the other end of the support frame.

[0003] Common tower crane cable fixing brackets only include the function of fixing cables, which can fix the cables, but lack adjustment function. They cannot guarantee the compatibility between the bracket and the tower crane connecting column. This can easily lead to the tower crane connecting column having different thicknesses, which means that the bracket cannot be installed on tower cranes with connecting columns of different thicknesses, affecting the problem of installation compatibility.

[0004] Therefore, to address the lack of adjustment function in the aforementioned tower crane cable fixing brackets, a new type of tower crane cable fixing bracket can be designed. By rotating the handle to turn the bidirectional screw forward or backward, the bidirectional screw drives two T-shaped sliding blocks to move closer or further apart. The two T-shaped sliding blocks, in turn, drive two clamping blocks to move closer or further apart through two connecting plates, until the distance between the two clamping blocks is adapted to the thickness of the tower crane connecting column. Then, the tower crane connecting column is clamped by the two clamping blocks, and finally, the two connecting blocks are fixed with bolts. This achieves the effect of adjusting the clamping distance according to the different thicknesses of the tower crane connecting columns. Utility Model Content

[0005] To overcome the common problem of tower crane cable fixing brackets lacking adjustment function and failing to ensure compatibility between the bracket and the tower crane connecting column, which is prone to having different thicknesses of tower crane connecting columns, the bracket cannot be installed on tower cranes with connecting columns of different thicknesses, thus affecting the problem of installation compatibility.

[0006] The technical solution of this utility model is as follows: a tower crane cable fixing bracket, including an adjusting plate; it also includes an adjusting groove, a sliding groove, a T-shaped sliding block, a connecting plate, a clamping block, and a two-way screw rod. The adjusting plate has an adjusting groove at the top, and a sliding groove is formed through the middle of the bottom end of the adjusting groove. Two T-shaped sliding blocks are symmetrically arranged at the left and right ends of the adjusting groove. The bottom end of the T-shaped sliding block is connected to the connecting plate through the sliding groove. A clamping block is provided at the bottom end of the connecting plate. A two-way screw rod is provided in the middle of the adjusting groove, and the two-way screw rod is threadedly connected to the two T-shaped sliding blocks.

[0007] Preferably, by rotating the handle to rotate the bidirectional lead screw in either the forward or reverse direction, the bidirectional lead screw drives two T-shaped sliding blocks to move closer or further apart. The two T-shaped sliding blocks, in turn, drive two clamping blocks to move closer or further apart through two connecting plates until the distance between the two clamping blocks matches the thickness of the tower crane connecting column. Then, the tower crane connecting column is clamped by the two clamping blocks, and finally, the two connecting blocks are fixed with bolts. This achieves the effect of adjusting the clamping distance according to the different thicknesses of tower crane connecting columns, thus solving the problem that common tower crane cable fixing brackets only include the function of fixing cables. While they can fix the cables, they lack adjustment functions and cannot guarantee the compatibility between the bracket and the tower crane connecting column. This can easily lead to tower crane connecting columns of different thicknesses, which means that the bracket cannot be installed on tower cranes with connecting columns of different thicknesses, affecting the problem of installation compatibility.

[0008] Preferably, two clamping slots are symmetrically provided on the right side of the left clamping block and the left side of the right clamping block, and two connecting blocks are symmetrically provided on the right side of the bottom middle of the left clamping block and the left side of the bottom middle of the right clamping block.

[0009] Preferably, the left end of the bidirectional lead screw is rotatably connected to the left side inside the adjustment groove, and the right end of the bidirectional lead screw passes through the adjustment plate and is connected to a rotating handle.

[0010] Preferably, a fixing plate is provided on the top of the adjusting plate, and the four corners of the fixing plate are fixed to the adjusting plate by bolts.

[0011] Preferably, a lower cable fixing block is provided in the middle of the top of the fixing plate, and an upper cable fixing block is provided on top of the lower cable fixing block.

[0012] Preferably, two fixing grooves are symmetrically provided at the middle of the top of the lower cable fixing block and at the middle of the bottom of the upper cable fixing block.

[0013] Preferably, connecting hinges are provided on the left side of the lower cable fixing block and the upper cable fixing block, and the connecting hinges are connected to the lower cable fixing block and the upper cable fixing block respectively by bolts.

[0014] The beneficial effects of this utility model are:

[0015] 1. By rotating the handle to turn the double-sided lead screw forward or backward, the double-sided lead screw drives the two T-shaped sliding blocks to move closer or further apart. The two T-shaped sliding blocks, in turn, drive the two clamping blocks to move closer or further apart through the two connecting plates. This continues until the distance between the two clamping blocks matches the thickness of the tower crane connecting column. The tower crane connecting column is then clamped by the two clamping blocks, and finally, the two connecting blocks are fixed with bolts. This achieves the effect of adjusting the clamping distance according to the different thicknesses of tower crane connecting columns. This solves the problem of common tower crane cable fixing brackets, which only include the function of fixing cables. While they can fix the cables, they lack adjustment functions and cannot guarantee the compatibility between the bracket and the tower crane connecting column. This can easily lead to tower crane connecting columns of different thicknesses, which means that the bracket cannot be installed on tower cranes with connecting columns of different thicknesses, affecting the problem of installation compatibility.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a tower crane cable fixing bracket, including an adjusting plate 1; it also includes an adjusting groove 2, a sliding groove 3, T-shaped sliding blocks 4, a connecting plate 5, a clamping block 6, and a bidirectional screw rod 10. The adjusting plate 1 has an adjusting groove 2 at its top, and a sliding groove 3 is formed through the middle of the bottom end of the adjusting groove 2. Two T-shaped sliding blocks 4 are symmetrically arranged at the left and right ends of the adjusting groove 2. The bottom end of each T-shaped sliding block 4 passes through the sliding groove 3 and is connected to the connecting plate 5. A clamping block 6 is provided at the bottom end of the connecting plate 5. A bidirectional screw rod 10 is arranged in the middle of the adjusting groove 2, and the bidirectional screw rod 10 is threadedly connected to the two T-shaped sliding blocks 4. By rotating the handle 9 to rotate the bidirectional screw rod 10 in either the forward or reverse direction, the bidirectional screw rod 10 drives the two T-shaped sliding blocks 4. The two T-shaped sliding blocks 4 move closer or further apart, and the two connecting plates 5 simultaneously drive the two clamping blocks 6 to move closer or further apart until the distance between the two clamping blocks 6 matches the thickness of the tower crane connecting column. Then, the two clamping blocks 6 clamp the tower crane connecting column, and finally, the two connecting blocks 8 are fixed with bolts. This achieves the effect of adjusting the clamping distance according to the different thicknesses of the tower crane connecting columns, thus solving the problem that common tower crane cable fixing brackets only have the function of fixing cables. They can fix the cables, but lack adjustment function, and cannot guarantee the compatibility between the bracket and the tower crane connecting column. This can easily lead to tower crane connecting columns of different thicknesses, which means that the bracket cannot be installed on tower cranes with connecting columns of different thicknesses, affecting the problem of installation compatibility.

[0024] Please see Figures 2-5 In this embodiment, a lower cable fixing block 12 is provided in the middle of the top of the fixing plate 11, and an upper cable fixing block 13 is provided on the top of the lower cable fixing block 12. Two fixing grooves 14 are symmetrically opened in the middle of the top of the lower cable fixing block 12 and the middle of the bottom of the upper cable fixing block 13. A connecting hinge 15 is provided on the left side of the lower cable fixing block 12 and the upper cable fixing block 13. The connecting hinge 15 is connected to the lower cable fixing block 12 and the upper cable fixing block 13 respectively by bolts. After the bracket is fixed to the tower crane connecting column, the cable is placed in the fixing groove 14 on the top of the lower cable fixing block 12. Then the upper cable fixing block 13 is rotated until the upper cable fixing block 13 and the lower cable fixing block 12 are in contact. At this time, the upper part of the cable is inserted into the fixing groove 14 at the bottom of the upper cable fixing block 13. Then the upper cable fixing block 13 and the lower cable fixing block 12 are fixed by bolts. The cable is clamped and fixed by the upper cable fixing block 13 and the lower cable fixing block 12.

[0025] Please see Figures 1-5In this embodiment, two clamping grooves 7 are symmetrically provided on the right side of the left clamping block 6 and the left side of the right clamping block 6. Two connecting blocks 8 are symmetrically provided on the right side of the bottom center of the left clamping block 6 and the left side of the bottom center of the right clamping block 6. The left end of the bidirectional lead screw 10 is rotatably connected to the left side inside the adjusting groove 2. The right end of the bidirectional lead screw 10 passes through the adjusting plate 1 and is connected to a rotating handle 9. A fixing plate 11 is provided on the top of the adjusting plate 1. The four corners of the fixing plate 11 are fixed to the adjusting plate 1 by bolts. By rotating the bidirectional lead screw 10 in the forward or reverse direction by rotating the rotating handle 9, the bidirectional lead screw... 10 drives the two T-shaped sliding blocks 4 to move closer or further apart. The two T-shaped sliding blocks 4, in turn, drive the two clamping blocks 6 to move closer or further apart through the two connecting plates 5. This continues until the distance between the two clamping blocks 6 is adapted to the thickness of the tower crane connecting column. Then, the two clamping blocks 6 clamp the tower crane connecting column. Finally, the two connecting blocks 8 are fixed with bolts. This achieves the function of adjusting the clamping distance according to the different thicknesses of the tower crane connecting columns, preventing the problem that the bracket cannot be installed on tower cranes with connecting columns of different thicknesses due to the inconsistent thickness of the tower crane connecting columns, thus affecting the installation compatibility.

[0026] During operation, rotating the handle 9 forward or backward rotates the bidirectional lead screw 10. The bidirectional lead screw 10 drives the two T-shaped sliding blocks 4 to move closer or further apart. The two T-shaped sliding blocks 4, in turn, drive the two clamping blocks 6 to move closer or further apart through the two connecting plates 5. This continues until the distance between the two clamping blocks 6 matches the thickness of the tower crane connecting column. The tower crane connecting column is then clamped by the two clamping blocks 6. Finally, the two connecting blocks 8 are fixed with bolts. After the bracket and the tower crane connecting column are fixed, the cable is placed in the fixing groove 14 at the top of the lower cable fixing block 12. Then, the upper cable fixing block 13 is rotated until it is in contact with the lower cable fixing block 12. At this time, the upper part of the cable is inserted into the fixing groove 14 at the bottom of the upper cable fixing block 13. The upper cable fixing block 13 and the lower cable fixing block 12 are then fixed with bolts. The upper cable fixing block 13 and the lower cable fixing block 12 clamp and fix the cable, realizing the function of adjusting the clamping distance according to the different thicknesses of the tower crane connecting columns.

[0027] Through the above steps, by rotating the handle 9 to rotate the bidirectional lead screw 10 in the forward or reverse direction, the bidirectional lead screw 10 drives the two T-shaped sliding blocks 4 to move closer or further apart. The two T-shaped sliding blocks 4, in turn, drive the two clamping blocks 6 to move closer or further apart through the two connecting plates 5, until the distance between the two clamping blocks 6 is adapted to the thickness of the tower crane connecting column. Then, the tower crane connecting column is clamped by the two clamping blocks 6, and finally, the two connecting blocks 8 are fixed by bolts. This achieves the effect of adjusting the clamping distance according to the different thicknesses of the tower crane connecting columns, thus solving the problem that common tower crane cable fixing brackets only have the function of fixing cables. They can fix the cables, but lack adjustment function, and cannot guarantee the compatibility between the bracket and the tower crane connecting column. This can easily lead to tower crane connecting columns of different thicknesses, which makes it impossible to install the bracket on tower cranes with connecting columns of different thicknesses, affecting the installation compatibility problem.
