Description

TECHNICAL FIELD

[0001] The utility model belongs to coal mine transportation equipment technical field, especially involves the tape winding device of two-way winding conveying belt. BACKGROUND

[0002] In the field of coal mine transportation, the belt conveyor bears the responsibility of transporting the mined coal from the underground to the ground due to its high efficiency, safety and economy. During the transportation process, the coal, the carrier roller and the driving drum continuously rub against the conveying belt for a long time, which may cause wear and tear of the conveying belt. In order to ensure the safe and efficient production of coal, the belt replacement work needs to be carried out irregularly. If the conveying belt is replaced manually, it will face the problems of high labor intensity, great safety hazards and long belt replacement time.

[0003] Currently, the work of collecting the conveying belt of the belt conveyor is usually completed by the tape winding device. The tape winding device limits the conveying belt by the pressing mechanism, then the conveying belt is pulled out by the belt pulling mechanism, and the conveying belt is wound up by the winding machine behind. The positions of the three mechanisms are fixed, and the pressing, pulling and winding operations are completed in turn. If two conveying belts with opposite conveying directions need to be collected underground, only one conveying belt can be collected first, then the tape winding device needs to be adjusted to the opposite direction to collect the other conveying belt, which increases the belt replacement time. If the working space underground cannot allow the tape winding device to turn, the tape winding device needs to be transported to the outside of the well for turning, which increases the labor intensity and working time of belt replacement and reduces the working efficiency.

[0035] Supporting legs 9 are connected to the two ends of the crossbeam 1, one end of each supporting leg 9 is connected to the crossbeam 1, and the other end is fixed to the ground, the supporting leg 9 has an inclination angle with the ground, the supporting leg 9 fixes the crossbeam 1 to the ground to form a rigid connection, greatly improves the overall stability of the winding device, and reduces the ground pressure by expanding the contact area of the winding device and the ground, for example, prevents the soft ground from sinking, and avoids deformation or inclination of the winding device due to local overload.

[0036] The driving motor 21, the crossbeam 1 and the support 3 are connected together through fastening bolts, the overall stability of the winding device is improved, and the winding device can be conveniently disassembled and transported.

[0037] Two beams 1 are jointly connected with a supporting roller 10, which is located at the middle position of the beams 1. When the conveying belt is extracted, the conveying belt extracted from the driving track 2 and the driven track 7 is placed on the supporting roller 10, and the supporting roller 10 bears the weight of the conveying belt through uniform load distribution, prevents the conveying belt from sagging due to gravity, increases the load of the winding machine 8, and thus maintains the stable operation of the winding machine 8.

[0038] In the embodiment, the driving track 2 and the driven track 7 adopt a steel-rubber composite track, which can not only ensure the strength of the track but also protect the conveying belt from damage, and can ensure the required traction of the conveying belt under the condition that the pressure per unit area of the conveying belt is minimized, and the steel-rubber composite track meets the requirements of antistatic and flame retardant.

[0039] A support two 5 is arranged at the inner side of the two supports one 3, and the support two 5 is connected with a hydraulic lifting cylinder two 6. In the embodiment, the support two 5 and the hydraulic lifting cylinder two 6 are connected by welding, which eliminates the risk of loosening between the support two 5 and the hydraulic lifting cylinder two 6, and enables the hydraulic lifting cylinder two 6 to work in a stable environment.

The hydraulic lifting cylinder one 4 and the hydraulic lifting cylinder two 6 are arranged on the two sides of the driven track 7, which can evenly share the load and avoid the bending of the piston rod one caused by local overload of the hydraulic lifting cylinder one 4.

[0041] When the limiting sliding rod 711 slides to the top end of the limiting sliding groove 521, the bottom of the driving track 2 is attached to the top of the driven track 7. The limiting sliding groove 521 limits the maximum lifting height of the hydraulic lifting cylinder two 6, preventing the clamping force between the driving track 2 and the driven track 7 from being too large to damage the conveying belt.

[0042] The bottom of the support one 3 is connected with a base one 31, and the bottom of the support two 5 is connected with a base two 51. The bottom ends of the base one 31 and the base two 51 are fixed to the ground. In the embodiment, the bottom of the base one 31 and the base two 51 is provided with a steel plate, which increases the contact area between the belt winding device and the ground, disperses the load received by the support one 3 and the support two 5, and improves the stability of the belt winding device.

[0043] Working principle: when the belt conveyor needs to change the belt, the conveyor belt is cut off, one end of the conveyor belt is placed between the driving track 2 and the driven track 7, the hydraulic lifting cylinder 1 and the hydraulic lifting cylinder 2 are controlled to lift the driven track 7, and the conveyor belt is clamped through the cooperation of the driving track 2 and the driven track 7, the driving motor 21 is started to drive the driving track 2 to rotate, the extraction of the conveyor belt can be realized, and the conveyor belt is wound through the winding machine 8 under the cross beam 1, if the belt conveyor in the opposite direction also needs to change the belt, the extraction of the conveyor belt can also be completed through the cooperation of the driving track 2 and the driven track 7 on the other side, through the driving track 2 and the driven track 7 arranged on both sides of the cross beam 1, the winding device can realize the extraction operation of the conveyor belt in the opposite two directions without turning direction, the time for turning the direction of the winding device is saved, the working efficiency of winding the conveyor belt is improved, and the cost is reduced.
