[0002] The self-moving tail of the belt conveyor is a key equipment for the rapid movement of the chute conveying equipment. With the construction of high-yield and high-efficiency mines, the technical development and research work on the self-moving tail of the belt conveyor is constantly advancing. Among them, the application of the self-moving tail of the large-stroke belt conveyor meets the demand of the coal mine working face to move the self-moving tail of the belt conveyor once a production shift.

[0003] When the chute height is small, it is necessary to reduce the overall coordination height of the transfer machine and the belt conveyor tail. The most effective solution is to use a flexible large-stroke chute transfer integrated machine, that is, the transfer machine slides forward on the belt conveyor tail. This solution causes rapid wear on the upper edge of the belt conveyor tail. In addition, due to the small coal passing space between the middle trough of the transfer machine and the middle frame of the belt conveyor tail, the life of the middle plate of the middle frame of the belt conveyor tail is relatively low.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0032] Please see Figures 1 to 5 The present invention provides a self-moving tail intermediate frame of a belt conveyor, comprising a side plate assembly 01, a middle plate assembly 02, a bottom plate 03, a lifting assembly 04, and a track 05; The side panel components 01 are symmetrically arranged on both sides of the bottom panel 03 , so that the side panel components 01 and the bottom panel 03 form an H-shaped structure.

[0033] The lifting assembly 04 is symmetrically arranged on the outer side of the side plate assembly 01 , and the lower end of the lifting assembly 04 is higher than the lowest end of the bottom of the side plate assembly 01 .

[0034] The middle plate assembly 02 includes an upper middle plate 21 and a lower middle plate 22; the lower middle plate 22 is arranged between the side plate assemblies 01, and a gap is left between the lower middle plate 22 and the bottom plate 03, so that a cavity for the belt to rotate is formed between the lower middle plate 22 and the bottom plate 03, and the upper middle plate 21 is arranged above the upper middle plate 21, and a gap is left between the upper middle plate 21 and the lower middle plate 22; the upper middle plate 21 adopts a "C" type structure with an angle between 20° and 30°. Under the action of the coal chute, the belt can slide automatically to prevent deviation; the lower middle plate 22 adopts a "bow" type structure and has good energy storage characteristics. The stored elastic potential energy can prevent the intermediate frame from being deformed or damaged due to the overload of the power unit of the transfer machine.

[0035] Track 05 is embedded in the side plate assembly 01 along the top of the side plate assembly 01, and the top of track 05 protrudes from the side plate assembly 01, so that the trolley of the transfer machine and the self-moving tail of the belt conveyor can run on track 05. Track 05 is installed in an embedded manner, which reduces the overall height of the self-moving tail of the belt conveyor, can reduce the overall height of the tunnel, reduce the tunnel excavation volume, save costs, and improve the safety factor of excavation work.

[0036] Please see Fig. 9In one embodiment, the side panel assembly 01 includes an inner panel 11, an outer panel 12, and a support panel 13; the inner panel 11 is symmetrically arranged on both sides of the bottom panel 03, the outer panel 12 is arranged on the side of the inner panel 11 away from the bottom panel 03, and a rib plate 14 is horizontally arranged between the outer panel 12 and the inner panel 11, so that a mounting groove capable of embedding the track 05 is formed between the outer panel 12 and the inner panel 11, and the support panel 13 is arranged at the bottom of both ends of the inner panel 11 and the outer panel 12. In this way, the side panel assembly 01 is formed into a double-layer structure as a whole, the path for transferring loads is increased, and the stress state of the single-layer vertical panel is optimized, which is conducive to providing a more stable support effect. The double-layer structure is used to replace the single-layer vertical panel + triangular rib plate 14, and the structure is more compact, which is conducive to reducing the width of the self-moving tail of the belt conveyor and increasing the matching passing space. The double-layer structure is not only high in strength, but also hydraulic pipelines and cable lines can be arranged inside.

[0037] Specifically, a support seat 23 for installing the lower middle plate 22 is provided on the inner plate 11, and the support seat 23 is fixed to the lower middle plate 22 with bolts; thereby realizing the detachable assembly of the middle plate assembly 02, so that after subsequent wear and tear occurs, it can be replaced at the position prone to wear, and the overall life of the equipment is increased.

[0038] In order to facilitate installation, a circular hole 24 facing the support seat 23 is opened on the upper middle plate 21 .

[0039] Please see Figure 6 , Figure 7 In one embodiment, anti-deviation sensors 06 are provided on both sides of the upper surface of the lower middle plate 22. The infrared rays of the anti-deviation sensors 06 can monitor the belt through the upper middle plate 21 of the middle plate assembly 02. When the sensor detects the belt signal (blocking the infrared signal), the side shift cylinder moves to adjust the belt position, thereby reducing the wear of the belt and the wear of the belt and the middle frame.

[0040] In one embodiment, pin holes 25 for mounting the rails 05 are provided on the inner plate 11 and the outer plate 12 .

[0041] Please see Fig.10Specifically, one end of the track 05 is provided with a double-ear structure 52 for connecting to the pin hole 25, and the other end of the track 05 is provided with a single-ear structure 53 for connecting to the pin hole 25. When the two intermediate frames are assembled and installed, the two adjacent guide rails must also be connected. At this time, the single-ear structure 53 of one track 05 needs to be connected to the double-ear structure 52 of the other track 05, that is, the double-ear structure 52 must be connected to the pin hole 25 and the single-ear structure 53, so that the junction of the two adjacent tracks 05 can be hinged, which reduces the height difference of the slot parts, is conducive to the smooth operation of the matching trolley, and reduces the risk of the transfer machine overturning. The track 05 and the side plate assembly 01 use a pin clearance fit, which can reduce the undulation angle of the adjacent slot guide rails and alleviate the impact of the undulation of the lane. Secondly, the track 05 uses a pin to achieve installation and fixation, so that it can be quickly and conveniently replaced after the track 05 is worn.

[0042] The upper surface of the track 05 is also provided with travel positioning holes 51 which are arranged at equal intervals along the track 05 .

[0043] Please see Figure 8 In one embodiment, the lifting component 04 includes an outer cylinder sleeve 41, an inner cylinder sleeve 42, a sliding shoe 43, and a lifting cylinder 44; the outer cylinder sleeve 41 is arranged on the outer plate 12, the inner cylinder sleeve 42 is fixedly arranged in the outer cylinder sleeve 41, the lifting cylinder 44 is installed in the inner cylinder sleeve 42, the upper end of the lifting cylinder 44 is fixedly connected to the upper end of the inner cylinder sleeve 42, and the lower end of the lifting cylinder 44 is connected to the sliding shoe 43. After the lower end of the lifting cylinder 44 is extended, the sliding shoe 43 can lift the middle part after contacting the ground. A side shift cylinder 45 and a sliding block 46 are arranged on the sliding shoe 43. One end of the side shift cylinder 45 is hinged on the sliding shoe 43, and the other end of the side shift cylinder 45 is hinged to the sliding block 46, so that the side shift cylinder 45 can drive the sliding block 46 to move back and forth along the sliding shoe 43, and the sliding block 46 is connected to the lower end of the lifting cylinder 44. The lifting cylinder 44 adopts a middle pin connection method. Under the condition of meeting the lifting stroke, the height of the intermediate frame can be greatly reduced, making the intermediate frame more compact and improving the strength and life of the intermediate frame.

[0044] In one embodiment, the present invention provides a self-moving tail of a belt conveyor, including an intermediate frame of the self-moving tail of the belt conveyor, and the self-moving tail intermediate frames of the belt conveyor are at least two, and each of the self-moving tail intermediate frames of the belt conveyor is assembled in a straight line in sequence.

[0045] In one embodiment, the present invention provides a chute conveying equipment, including the self-moving tail of the belt conveyor and a transfer machine.
