Description

Technical Field

[0001] This utility model relates to the field of coal mine electromechanical equipment technology, specifically a cable winding and unwinding device for coal mine electromechanical equipment. Background Technology

[0002] During coal mining operations, the normal operation of electromechanical equipment (such as coal mining machines, scraper conveyors, and tunneling machines) is inseparable from the power and signal transmission of cables. Due to the complex working space and dynamic changes in the working range in coal mines, electromechanical equipment needs to be moved continuously with the mining progress, which requires cables to be flexible in deployment and retraction.

[0003] Based on the above, the inventors have discovered the following problems: the current common method of cable winding and unwinding in coal mines is manual dragging, which is labor-intensive, inefficient, and affects the use of electromechanical equipment.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a cable winding and unwinding device for coal mine electromechanical equipment, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a cable reeling and unloading device for coal mine electromechanical equipment, in order to solve the problem mentioned in the background art that the current common cable reeling and unloading methods in coal mines are mostly manual dragging and unloading, which is labor-intensive, inefficient, and affects the use of electromechanical equipment.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

A support plate is installed at the top of the base frame, and a fixed seat is installed at the middle of the top of the support plate. A rotating shaft is rotatably connected to the inner side of the fixed seat, and a turntable is fitted on the outer side of the rotating shaft. Several sliding lifting mechanisms for supporting the turntable are installed at the top of the support plate. A vertical pole is installed on one side of the top of the base frame, and a push rod is installed at the top of the vertical pole. A drive mechanism for rotating the turntable is installed on one side of the top of the base frame, and a positioning mechanism for limiting the rotation of the turntable is installed on the other side of the top of the base frame.

[0008] Furthermore, the drive mechanism includes a first retainer, the bottom end of the first retainer is fixedly connected to one side of the top end of the base frame, a motor is mounted on one end face of the first retainer, a bevel gear is mounted on the output end of the motor, and a bevel gear ring is mounted on the bottom end of the turntable, the bevel gear and the bevel gear ring meshing.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the motor is fixed by the first cage of the drive mechanism, which ensures the stable operation of the motor; and the high-speed rotation of the motor is converted into the low-speed stable rotation of the turntable by the meshing of the bevel gear at the output end of the motor with the bevel gear ring at the bottom end of the turntable.

[0010] Furthermore, the positioning mechanism includes a second retainer, the bottom end of which is fixedly connected to the other side of the top end of the base frame, a positioning screw is installed on the inner side of the second retainer, and a plurality of positioning holes are opened on the outer side of the turntable, with one end of the positioning screw inserted into the inner side of the positioning hole.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the positioning screw is fixed by the second retainer of the positioning mechanism to ensure stable movement of the screw. The positioning screw is inserted into the positioning hole on the outside of the turntable by one end, locking the rotation of the turntable and preventing the turntable from rotating accidentally after the cable is retracted or transferred.

[0012] Furthermore, one end of the positioning screw is arc-shaped, and the other end of the positioning screw is equipped with an adjustment knob.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the arc shape of one end of the positioning screw reduces the frictional resistance between the screw and the positioning hole, making it easier to insert or pull out the screw. The adjustment knob at the other end of the positioning screw increases the force application radius and reduces the operating force.

[0014] Furthermore, the sliding lifting mechanism includes a retaining seat, the bottom end of which is fixedly connected to the top end of the support plate, and a ball bearing is rotatably connected to the top end of the retaining seat, with the top end of the ball bearing in contact with the bottom end of the turntable.

[0016] Furthermore, a wire threader is installed on one side of the push rod.

[0017] The advantage of adopting the above-mentioned further solution is that the cable is guided to move along a fixed path during cable winding and unwinding by the cable guide on one side of the push rod, thus avoiding cable tangling and mess.

[0018] Furthermore, omnidirectional wheels are installed at the four corners of the bottom of the base frame, and a brake foot plate is connected to one side of each omnidirectional wheel.

A support plate 3 is installed at the top of the base frame 1, and a fixed seat 4 is installed at the center of the top of the support plate 3. A rotating shaft 5 is rotatably connected to the inner side of the fixed seat 4, and a turntable 6 is fitted onto the outer side of the rotating shaft 5. Several sliding lifting mechanisms 7 for supporting the turntable 6 are installed at the top of the support plate 3. A vertical rod 8 is installed on one side of the top of the base frame 1, and a push rod 9 is installed at the top of the vertical rod 8. A drive mechanism 11 for rotating the turntable 6 is installed on one side of the top of the base frame 1, and a positioning mechanism 12 for limiting the rotation of the turntable 6 is installed on the other side of the top of the base frame 1. The cross shape of the turntable 6 forms a stable support structure, preventing the device from tipping over during cable retraction and making it suitable for uneven ground in coal mines. The support plate 3 provides a flat installation base for the fixed seat 4 and the sliding lifting mechanism 7, ensuring stable rotation of the turntable 6. The fixed seat 4 supports the rotation of the rotating shaft 5, preventing the shaft 5 from bending. The turntable 6 winds the cable, replacing manual dragging. The sliding lifting mechanism 7 reduces the rotational resistance of the turntable 6, lowering the load on the drive mechanism 11. The upright pole 8 and the push rod 9 provide convenient force application points, facilitating the movement of the device. The drive mechanism 11 provides power to achieve automatic cable retraction and extension. The positioning mechanism 12 locks the turntable 6 to prevent accidental cable detachment.

[0029] The drive mechanism 11 includes a first retainer 1101, the bottom end of which is fixedly connected to one side of the top of the base frame 1. A motor 1102 is mounted on one end face of the first retainer 1101. A bevel gear 1103 is mounted on the output end of the motor 1102. A bevel gear ring 1104 is mounted on the bottom end of the turntable 6. The bevel gear 1103 and the bevel gear ring 1104 mesh. The motor 1102 is fixed by the first retainer 1101 of the drive mechanism 11 to ensure stable operation of the motor 1102. The high-speed rotation of the motor 1102 is converted into low-speed stable rotation of the turntable 6 by the meshing of the bevel gear 1103 at the output end of the motor 1102 with the bevel gear ring 1104 at the bottom end of the turntable 6.

[0030] The positioning mechanism 12 includes a second retainer 1201, the bottom end of which is fixedly connected to the other side of the top of the base frame 1. A positioning screw 1202 is installed on the inner side of the second retainer 1201. Several positioning holes 601 are opened on the outer side of the turntable 6. One end of the positioning screw 1202 is inserted into the inner side of the positioning hole 601. The positioning screw 1202 is fixed by the second retainer 1201 of the positioning mechanism 12 to ensure stable movement of the screw. The rotation of the turntable 6 is locked by inserting one end of the positioning screw 1202 into the positioning hole 601 on the outer side of the turntable 6 to prevent the turntable 6 from rotating accidentally after the cable is retracted or during transportation.

[0031] One end of the positioning screw 1202 is arc-shaped, and the other end of the positioning screw 1202 is equipped with an adjustment knob 1203. The arc shape of one end of the positioning screw 1202 reduces the frictional resistance between the screw and the positioning hole 601, making it easier for the screw to be inserted or pulled out. The adjustment knob 1203 at the other end of the positioning screw 1202 increases the force application radius and reduces the operating force.

[0032] The sliding lifting mechanism 7 includes a retaining seat 701, the bottom end of which is fixedly connected to the top end of the support plate 3.

The ball bearing 702 is fixed by the retaining seat 701 of the sliding lifting mechanism 7 to ensure stable rotation of the ball bearing 702. The contact between the top end of the ball bearing 702 and the bottom end of the turntable 6 converts the sliding friction between the turntable 6 and the support plate 3 into rolling friction.

[0033] One side of the push rod 9 is equipped with a cable guide 10. The cable guide 10 on one side of the push rod 9 guides the cable to move along a fixed path during cable winding and unwinding, thus avoiding cable tangling and mess.

[0034] Among them, the four corners of the bottom of the base frame 1 are equipped with casters 2, and one side of the caster 2 is connected to a brake foot plate. The casters 2 at the four corners of the bottom of the base frame 1 enable the device to turn flexibly and adapt to the narrow passages in the coal mine.

The positioning screw 1202 ensures stable screw movement. One end of the positioning screw 1202 is inserted into the positioning hole 601 on the outer side of the turntable 6 to lock the rotation of the turntable 6, preventing accidental rotation of the turntable 6 after cable winding or unwinding or during transfer. The arc shape of one end of the positioning screw 1202 reduces the frictional resistance between the screw and the positioning hole 601, making it easier for the screw to be inserted or removed. The adjustment knob 1203 at the other end of the positioning screw 1202 increases the force application radius and reduces the operating force. The ball bearing 702 is fixed by the retaining seat 701 of the sliding lifting mechanism 7 to ensure the rolling... The ball 702 rotates stably. By contacting the bottom of the turntable 6 with the top of the ball 702, the sliding friction between the turntable 6 and the support plate 3 is converted into rolling friction. The cable guide 10 on one side of the push rod 9 guides the cable to move along a fixed path during cable winding and unwinding, avoiding cable tangling and mess.
