Description

Technical Field

[0001] The utility model relates to the field of mine transportation, in particular to a supporting belt tail self-moving device. Background Art

[0002] In the process of raw coal transportation in mine production, as the working face continues to advance, the transfer machine chute must move forward with the working face, and the transport belt must be shortened synchronously with the advancement of the chute. In the previous operation process, mine workers used multi-point installation of return column winches to pull the wire rope, which not only has a high risk factor, but also has high labor intensity and low production efficiency. In order to solve these problems, it is proposed to design and manufacture a supporting belt tail self-moving device. Utility Model Content

[0003] The purpose of the utility model is to provide a supporting belt tail self-moving device to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A supported belt tail self-moving device comprises a base, a belt for conveying materials is laid on the upper end of the base, a belt tail receiving roller frame is provided on one side of the base, the belt is laid on the belt tail receiving roller frame, a push cylinder is provided between the belt tail receiving roller frame and the base, a bottom support plate is laid under the belt receiving rod, a bottom lifting device is made at the front end of the base, a vertically arranged supporting jack is provided at the upper end of the base, and the telescopic end of the supporting jack is connected to the top beam.

[0006] As a further solution of the utility model: the telescopic direction of the push cylinder is horizontal.

[0007] As a further solution of the utility model: the top beam and the base are also provided with a four-link frame.

[0008] As a further solution of the utility model: a balancing jack is further provided between the four-link frame and the top beam.

[0009] As a further solution of the utility model: a bottom support plate is laid under the belt receiving rod.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the equipment is arranged between the transfer machine chute and the transport belt, with a frame-type hydraulic support as the anchor point, a hydraulic system as the power, and a hydraulic cylinder as the moving medium. When the working surface moves forward, the support frame touches the top under the action of the hydraulic system and plays the role of an anchor point. Since the support frame adopts a frame structure, it will not cause damage to the top plate and the bottom plate of the tunnel. At the same time, the hydraulic cylinder performs retraction work, and pulls the transport belt tail frame group, that is, a plurality of linked belt receiving stick frames, forward. As the belt tail is pushed into place, the support frame retracts and is fixed by the deadweight of the entire set of belt tail frames. As the cylinder extends, the support frame is pushed forward, and the action is repeated several steps to complete a certain distance of the belt retraction work cycle, remove the redundant H-shaped three-section stick frame in the middle, and the retracted belt is tightened by the belt storage bin of the belt conveyor.

[0011] The production and commissioning of this equipment has successfully solved the problem of continuously reducing the belt tail and dragging the belt receiving rod frame group during the raw coal production process, realized the self-movement of the belt tail, greatly improved the safety factor in the belt reduction work, eliminated the phenomenon of "hard pulling" at work, reduced the labor intensity of front-line workers, and improved labor efficiency.

[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] Embodiment 1:

[0018] See also Figure 1-3In the embodiment of the utility model, a supported belt tail self-moving device comprises a base 4, a belt 8 for conveying materials is installed on the upper end of the base 4, a belt tail receiving roller frame 7 is provided on one side of the base 4, the belt 8 is laid on the belt tail receiving roller frame 7, a push cylinder 5 is provided between the end frame 6 of the belt tail receiving roller frame 7 and the base, a vertically arranged support jack 9 is provided on the upper end of the base 4, the telescopic end of the support jack 9 is connected to the top beam 1, a bottom lifting device 10 is provided at the forward end of the base 4, a bottom support plate 11 is laid at the lower part of the belt tail receiving roller frame 7, a bottom support plate 10 is provided at the lower part, and the telescopic direction of the push cylinder 5 is horizontal;

[0019] In order to ensure the stability of the top beam 1, a four-link frame 3 is provided between the top beam 1 and the base 4, and a balancing jack 2 is provided between the four-link frame 3 and the top beam 1. The balancing jack 2, the four-link frame 3 and the supporting jack 9 ensure the stability of the force on the base 4.

[0020] When in use, in the initial state, the push cylinder 5 is in a retracted state, and the supporting jack 9 is also in a retracted state;

[0021] When the belt tail needs to move forward, the push cylinder 5 extends to push the base 4 and the balance jack 2, the four-link frame 3, the support jack 9 and the top beam connected to the base 4 forward (such as Figure 2 shown);

[0022] When the push cylinder 5 is extended to the right position, the support jack 9 extends upward, and cooperates with the balance jack 2 and the four-link frame 3 to make the top beam 1 contact and bear force in the vertical direction, and form a stable force support (such as Figure 3 shown);

[0023] After the top beam 1 is supported and stabilized, the push cylinder 5 is retracted. Since the base 4 is fixed by force, the belt tail receiving roller frame 7 is pulled forward to realize the self-movement of the belt tail. This action step is repeated according to the actual propulsion distance requirements.

[0024] This set of equipment is set between the transfer machine chute and the transport belt, with a frame-type hydraulic support as the anchor point, a hydraulic system as the power, and a hydraulic cylinder as the moving medium. When the working surface moves forward, the support frame touches the top under the action of the hydraulic system and acts as an anchor point. Since the support frame adopts a frame structure, it will not cause damage to the top and bottom plates of the tunnel. At the same time, the hydraulic cylinder performs a contraction work to drag the receiving rod frame group at the tail of the transport belt forward. After the tail of the belt is dragged into place, the support frame retracts and is fixed by the deadweight of the entire set of belt tail frames. As the cylinder extends, the support frame moves forward and is towed again to complete several working cycles to reach the contracted belt length.

[0025] The production and commissioning of this equipment has successfully solved the problem of continuously reducing the belt in the process of raw coal production, realized the self-movement of the belt tail, greatly improved the safety factor in the work of reducing the belt, eliminated the phenomenon of "hard pulling" in the work, reduced the labor intensity of front-line workers, and improved labor efficiency.
