Description

Technical Field

[0001] The utility model belongs to the technical field of mine hoist equipment, and in particular relates to a device for eliminating the torsion of a hoisting rope of a mine hoist. Background Art

[0002] Mine hoist is an important auxiliary mechanical equipment in the process of ore mining. It is mainly used to lift coal mines, mines, gangue, lower materials, lift personnel and equipment. It plays an important role in the transportation of personnel and materials above and below the well. It is the "throat" equipment connecting the mine underground and the ground. The counterweight is a connection device used to balance the load and reduce the static difference of the lifting wire rope on the drum on the mine hoist. It is connected to the main hanging plate and the fixed shaft on the counterweight frame, and then connected to the main hanging plate with a wedge-shaped rope clamp connection device. The lifting wire rope passes around the wedge-shaped rope clamp and is fixed with a rope clamp to form a complete connection device. During installation, the entire connection device is hoisted into the wellbore through a winch, and then the counterweight is installed on two wire rope tanks with a wire rope sliding sleeve, so that the counterweight can run up and down in the wellbore.

[0003] There are the following disadvantages in actual use: First, it is difficult to hoist. During the hoisting process, when the counterweight is placed in the wellbore, the lifting wire rope generates a rotational force due to gravity, and at the same time drives the counterweight to rotate. Since the distance between the two wire ropes is fixed, the counterweight is easily twisted with the wire rope, and the operator needs to enter the wellbore for repeated adjustments to completely release the rotational force of the wire rope, which causes great difficulties in replacing the lifting wire rope. Second, it consumes unnecessary costs and has a low safety factor. Working in the wellbore is an aerial operation. In actual operation, an operating platform must be set up and the operator is required to wear a safety belt. After all adjustment operations are completed, the built platform must be dismantled to ensure that the counterweight and the bucket can move freely up and down in the well without collision. At the same time, there are many unpredictable safety hazards in working in the well, such as whether there is floating stone on the wall of the well, whether the sheave platform is intact, and whether there are objects falling on the sheave platform.

Detailed Embodiment

[0017] The present utility model will be further described below with reference to the drawings and embodiments.

[0018] As Figure 1-2As shown in the figure, a device for eliminating the torsion of the hoisting rope of a mine hoist includes a steel wire rope 1, a wedge rope clip 2, a main suspension plate 3, a balance frame 5, and a steel wire rope guide 7, and also includes a turntable 4. The steel wire rope 1 is sleeved in the middle of the wedge rope clip 2. The main suspension plate 3 is arranged at the lower end of the wedge rope clip 2. The upper end of the turntable 4 is connected to the main suspension plate 3, and the lower end of the turntable 4 is connected to the balance frame 5. The steel wire rope guide 7 is arranged at both ends of the balance frame 5. The setting of the turntable avoids building an operation platform in the shaft, reduces the labor intensity of the operators, reduces the cost, and at the same time reduces the potential safety hazards during high-altitude operations;

[0019] The turntable 4 includes two turntable frames 4-2, a thrust bearing 4-5, a thrust bearing seat 4-6, a tapered bearing seat 4-7, a tapered bearing 4-8, and a shaft rod 4-10;

[0020] The turntable frame 4-2 is formed by welding two iron plates through a bottom plate. The thrust bearing seat 4-6 is arranged on the top surface of the bottom plate. The tapered bearing seat 4-7 is arranged on the bottom surface of the bottom plate. The thrust bearing 4-5 is arranged on the thrust bearing seat 4-6. The tapered bearing 4-8 is arranged on the tapered bearing seat 4-7. The turntable frame 4-2 is movably connected to the shaft rod 4-10 through the thrust bearing 4-5, the tapered bearing 4-8, and a nut 4-3. The turntable frame 4-2 and the shaft rod 4-10 can rotate relative to each other freely, releasing the rotational force generated by the steel wire rope 1. There is an upper retaining ring 4-4 between the nut 4-3 and the thrust bearing 4-5, and a lower retaining ring 4-9 between the tapered bearing seat 4-7 and the shaft rod 4-10. The upper end of the turntable frame 4-2 is connected to the main suspension plate 3 through an upper ring shaft 4-1, and the lower end of the shaft rod 4-10 is connected to the balance frame 5 through a lower ring shaft 4-11.

[0021] The working process of the present utility model:

[0022] When the present utility model is in use, the steel wire rope 1 is sleeved on the wedge rope clip 2, and the balance frame 5 is connected to the shaft rod 4-10. The steel wire rope 1 rises upward, lifting the balance frame 5. During the lifting process, the steel wire rope 1 generates a rotational force due to gravity. The rotational force of the steel wire rope 1 passes through the wedge rope clip 2, the main suspension plate 3, and the turntable frame 4-2. The turntable frame 4-2 and the shaft rod 4-10 are connected through the thrust bearing 4-5 and the tapered bearing 4-8, so that the turntable frame 4-2 and the shaft rod 4-10 can rotate relative to each other freely. The rotational force generated by the steel wire rope 1 is released through the rotation of the turntable frame 4-2, avoiding driving the shaft rod 4-10 to rotate, thereby avoiding the balance weight and the steel wire rope guide from twisting together. In addition, it can prevent operators from entering the shaft to adjust the steel wire rope, reducing the operation intensity and improving the operation safety.
