In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Please refer to Figure 1-4As shown, the tension wire guide rope drum control device includes a track slide 1, the upper end of the bracket of the track slide 1 is symmetrically slidably connected with two groups of guide rail frames 2, and a hydraulic lift 3 with a top support seat 6 is installed in the middle of the slide rail of the guide rail frame 2. The hydraulic lift 3 includes a hydraulic lift rod 31 and a pedal 32 installed at the oil circuit end of the hydraulic lift rod 31. After the wire pay-off drum 10 is installed on the transmission shaft 8, the combination of the hydraulic lift rod 31 and the pedal 32 in the hydraulic lift 3 is used. The worker operates the foot pedal 32 to control the flow of the hydraulic oil circuit in the hydraulic lift rod 31, and the piston rod of the hydraulic lift rod 31 is pushed out to push the wire pay-off drum 10 up. On the contrary, when the hydraulic oil flows back, the piston rod retracts and the wire pay-off drum 10 descends, thereby realizing the rapid winding and wire pay-off of the wire pay-off drum 10. It replaces the traditional manual handling or crane lifting method, and the operation is safe, convenient and efficient, and the handling cost is low.

[0026] Both ends of the slide rails of each group of guide rail frames 2 are slidably connected with guide slides 5, and the upper ends of the frames of the two groups of guide slides 5 are symmetrically connected with two groups of side support brackets 4, and the top ends of the arm rods of the two groups of side support brackets 4 are connected to the support seats 6, and both ends of the arm rods of the side support brackets 4 are provided with rotating seats connected with the guide slides 5 and the support seats 6. An isosceles triangle structure is formed between the two groups of side support brackets 4 and the guide rail frames 2. When the hydraulic lift 3 supports the lifting and braking of the pay-off drum 10, the triangular telescopic frame structure formed between the side support brackets 4 and the guide rail frames 2 has good side support stability, can improve the stability of the overall structure, ensure that the pay-off drum 10 leaves the ground smoothly, and avoid accidental injuries caused by improper operation.

[0027] The support seat 6 is internally rotatably connected with a transmission shaft 8, and a pay-off reel 10 is fixedly sleeved on the outer side of the shaft rod of the transmission shaft 8, and a brake disc 9 close to the support seat 6 is arranged at one end of the shaft rod of the transmission shaft 8, and a brake mechanism 7 opposite to the brake disc 9 is arranged on one side of the support seat 6, and the brake mechanism 7 includes a brake sleeve 71 mounted on the support seat 6, and a clamping screw rod 76 is rotatably connected to the middle part of the clamping sleeve of the brake sleeve 71, and a rotating handle 72 is arranged at one end of the shaft rod of the clamping screw rod 76, and two groups of clamping screw sleeves 77 are symmetrically sleeved on the outer side of the shaft rod of the clamping screw rod 76, and arm force guide plates 73 are sleeved and fixed on the outer sides of the shaft sleeves of the two groups of clamping screw sleeves 77, and brake pads 74 clamped opposite to the brake disc 9 are arranged on the clamping surfaces of the two groups of arm force guide plates 73. The wire clamping rod 76 is bounded by the center line, and the two sides of the center line are symmetrically provided with positive and negative threads compatible with the wire clamping sleeve 77. The inner wall of the brake sleeve 71 is symmetrically provided with a guide groove 75 that guides the arm guide plate 73. During the process of paying off the wire on the wire reel 10, when the staff needs to control the rotation speed of the wire reel, they can rotate the rotating handle 72 to drive the wire clamping rod 76 to rotate. The positive and negative threads on the wire clamping rod 76 are driven to push the combination of the wire clamping sleeve 77 and the arm guide plate 73 to slide symmetrically along the guide groove 75, so that the brake pad 74 on the arm guide plate 73 is clamped in a manner, and friction with the brake pad 74 generates resistance, thereby slowing down or stopping the rotation of the wire reel 10, effectively solving the problem of the difficulty in controlling the rotation speed of the wire reel 10.

[0028] The working principle of the utility model is as follows: during the use of the wire drum control device, firstly, two sets of track slides 1 are placed on both sides of the wire drum 10, and then two sets of guide rail frames 2 are slidably installed on the track slides 1 in a horizontally relative manner, and the transmission shaft 8 is opposite to the central axis of the wire drum 10, so that the transmission shaft 8 is used as a rotating component to push the wire drum 10 to wind and pay out the wire. After the wire drum 10 is installed on the transmission shaft 8, the combination of the hydraulic lifting rod 31 and the pedal 32 in the hydraulic lift 3 is used, and the worker operates the foot pedal 32 to control the flow of the hydraulic oil circuit in the hydraulic lifting rod 31, and the piston rod of the hydraulic lifting rod 31 is pushed out to push the wire drum 10 up, so as to ensure that the wire drum 10 is stably off the ground, and the fast winding and paying out of the wire drum 10 is realized;

[0029] The rotation of the pay-off reel 10 is slowed down or stopped by the friction between the brake pads 74 and the brake guide plate 73, thereby solving the problem of the difficulty in controlling the rotation speed of the pay-off reel 10 and facilitating the staff to control the pay-off speed of the pay-off reel 10 more smoothly.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
