[0005] To overcome the shortcomings of existing technologies and address the problems caused by limitations in the structural design or functional configuration of current cable trolleys, most trolleys currently use bolts to fix cables. However, this fixing method requires multiple tightening and adjustment of the bolts, which is not only extremely inefficient, but also the tightening force is largely affected by the operator's experience. Excessive or insufficient clamping force may lead to excessive wear on the cable sheath.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The cable trolley of this utility model, by setting a connecting column, with the connecting column serving as the main frame of the trolley, and the two side support plates forming a stable triangular structure, disperses the force on the cable and reduces local stress concentration. A pulley is fixed at the bottom of the connecting plate to realize the linear movement of the trolley along the cable track. The first vertical plate serves as the mounting base for the clamping plate. The clamping plate is driven to move relative to the cable by a power component, realizing the automatic clamping and release of the cable.

When the bidirectional lead screw rotates, a pair of first vertical plates will move relative to each other, causing a pair of pushing blocks to drive the second L-shaped plate to move. The connecting block will extend into the through hole and squeeze the locking block, causing the locking block to move downward in the third slide groove. The spring pushes the locking block to embed into the vertical locking groove, forming a self-locking mechanism, which can prevent the bidirectional lead screw from rotating due to external force.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown in the embodiment of this utility model, a cable trolley includes a connecting column 1; support plates 2 are fixedly connected to both sides of the connecting column 1; a pair of connecting plates 3 are fixedly connected to the bottom ends of each pair of support plates 2; a pulley 4 is provided on one side of each pair of connecting plates 3; a pair of first vertical plates 5 are provided at the top of the connecting column 1; a cable clamping plate 6 is provided on the opposite side of each pair of first vertical plates 5; a first L-shaped plate 7 is fixedly connected to the top of each pair of support plates 2; a first vertical plate 5 is penetrated on one side of each pair of first L-shaped plates 7; a power component is provided inside the connecting column 1; the power component is used to drive... The cable clamping plates 6 are moved by a pair of moving parts. During operation, the connecting column 1 is set up, which serves as the main frame of the trolley. The two side support plates 2 form a stable triangular structure to distribute the force on the cable and reduce local stress concentration. The pulley 4 is fixed at the bottom of the connecting plate 3 to realize the linear movement of the trolley along the cable track. The first vertical plate 5 serves as the mounting base for the clamping plate. The clamping plate is driven to move relative to each other by a power component to realize the automatic clamping and release of the cable. The first L-shaped plate 7 can form a sliding guide structure for the first vertical plate 5 to ensure that the clamping plate moves only along the axial direction and avoids uneven clamping force caused by deflection.

[0024] The power component includes a bidirectional lead screw 8; the bidirectional lead screw 8 is rotatably connected inside the connecting column 1, and both ends extend to one side of the support plate 2; a first sliding groove 9 is provided at the top of the connecting column 1; a pair of sliders 10 are slidably connected in the first sliding groove 9; the pair of sliders 10 are respectively fixed to the bottom ends of a pair of first vertical plates 5; the pair of first vertical plates 5 are slidably connected to the top of the connecting column 1; both ends of the bidirectional lead screw 8 are fixedly connected to rotating wheels 11. During operation, by opening the first sliding groove 9 at the top of the connecting column and rotatably connecting the bidirectional lead screw 8 in the first sliding groove 9, when the operator rotates the rotating wheels 11, the bidirectional lead screw 8 rotates, causing the pair of sliders 10 to move synchronously in opposite directions along the axial direction. The sliders 10 are fixed to the first vertical plates 5, driving the cable clamping plates 6 on both sides to move towards or away from each other, realizing the automatic centering, clamping and releasing of the cable.

[0025] Each pair of first L-shaped plates 7 has a second sliding groove 12 on one side; a second L-shaped plate 13 is slidably connected within each pair of second sliding grooves 12; a through hole 14 is provided on one side of one of the pair of second L-shaped plates 13; a connecting block 15 is fixedly connected to one side of one of the pair of second L-shaped plates 13; a vertical slot 16 is provided on the outer circular wall of the connecting block 15; a third sliding groove 17 is provided within the through hole 14; a locking block 18 is slidably connected within the third sliding groove 17 via a spring; the connecting block 15 is slidably connected inside the through hole 14; a pusher is fixedly connected to one side of each pair of first vertical plates 5. Block 19; the other side of the pair of push blocks 19 is respectively fixed to one side of the second L-shaped plate 13. During operation, by opening a second slide groove 12 in a pair of first L-shaped plates 7, and setting the second L-shaped plate 13 in the second slide groove 12, when the bidirectional lead screw 8 rotates, a pair of first vertical plates 5 will move relative to each other, causing a pair of push blocks 19 to drive the second L-shaped plate 13 to move. The connecting block 15 will extend into the through hole 14 and press against the locking block 18, causing the locking block 18 to move downward in the third slide groove 17. The spring pushes the locking block 18 to embed into the vertical locking groove 16, forming a self-locking mechanism, which can prevent the bidirectional lead screw 8 from rotating due to external force.

[0026] A through groove 20 is provided on one side of one of the pair of second L-shaped plates 13; a pair of push rods 21 are provided in the through groove 20; the pair of push rods 21 are respectively fixed to both sides of the locking block 18. During operation, by opening the through groove 20 on one side of the second L-shaped plate 13 and setting the push rods 21, when it is necessary to disassemble the trolley, the pair of push rods 21 can be pressed down to move the locking block 18 downward, so that the locking block 18 moves out of the vertical locking groove 16, thereby canceling the self-locking between the connecting block 15 and the bidirectional lead screw 8.

[0027] The bidirectional lead screw 8 is coated with an anti-corrosion coating. During operation, the metal coating on the bidirectional lead screw 8 provides wear resistance and corrosion resistance, preventing excessive corrosion.

[0028] The cable clamping plate 6 is provided with an anti-slip rubber pad 22 on its clamping surface. During operation, the clamping effect of the cable clamping plate 6 can be improved by providing the anti-slip rubber pad 22 on its clamping surface.

[0029] Working Principle: A connecting column 1 serves as the main frame of the trolley, with two supporting plates 2 forming a stable triangular structure to distribute cable stress and reduce local stress concentration. A pulley 4 is fixed at the bottom of the connecting plate 3, enabling linear movement of the trolley along the cable track. The first vertical plate 5 serves as the mounting base for the clamping plates. A power component drives the clamping plates to move relative to each other, achieving automatic clamping and release of the cable. The first L-shaped plate 7 forms a sliding guide structure for the first vertical plate 5, ensuring that the clamping plates move only axially and preventing uneven clamping force due to deflection. A first sliding groove 9 is opened at the top of the connecting column, and a bidirectional screw 8 is rotatably connected within the first sliding groove 9. When the operator rotates the rotating wheel 11, the bidirectional screw 8 rotates, causing a pair of sliders 10 to move synchronously in opposite directions axially. The sliders 10 are fixed to the first vertical plate 5, driving the cable clamping plates 6 on both sides to move towards or away from each other, achieving automatic centering, clamping, and release of the cable. A second sliding groove 12 is opened on the pair of first L-shaped plates 7. A second L-shaped plate 13 is installed in the second slide groove 12. When the bidirectional lead screw 8 rotates, a pair of first vertical plates 5 will move relative to each other, causing a pair of push blocks 19 to drive the second L-shaped plate 13 to move. The connecting block 15 will extend into the through hole 14, pressing the locking block 18 and causing the locking block 18 to move downward in the third slide groove 17. The spring pushes the locking block 18 into the vertical locking groove 16, forming a self-locking mechanism, which can prevent the bidirectional lead screw 8 from rotating due to external force. This is achieved by opening a groove on one side of the second L-shaped plate 13. The through slot 20 is provided with push rods 21. When the trolley needs to be disassembled, a pair of push rods 21 can be pressed down to move the locking block 18 downwards and move the locking block 18 out of the vertical locking slot 16. This cancels the self-locking between the connecting block 15 and the bidirectional lead screw 8. By spraying a metal coating on the bidirectional lead screw 8, wear resistance and corrosion resistance are improved, and excessive corrosion is avoided. By setting anti-slip rubber pads 22 on the clamping surface of the cable clamping plate 6, the clamping effect of the cable clamping plate 6 can be improved.
