The two rails 3 are arranged in parallel, and the length of the rails 3 and the distance between the two rails are set as required. For example, in one embodiment, the length of the track is 40 meters.

Each track 3 is formed by splicing a plurality of circular tube-shaped sub-tracks 31 in order to facilitate the arrangement under the well. The radial inner side of the splicing part of the adjacent round tubular sub-rails 31 is sleeved with a connecting piece 32, and the connecting piece 32 is connected with the round tubular sub-rails 31 into a whole through connecting pins 33.

Preferably, the length of each circular tubular sub-rail 31 is 6 m or less.

Referring to fig. 2, the upper end of each frame 7 is provided with a conveyor belt support 71 for supporting the conveyor belt. The specific shape, number, arrangement, etc. of the belt supports 71 may be set as desired.

The frame 7 at the head end is fixedly connected to the two rails 3 at the lower end both sides, respectively. That is, the left side of the lower end of the frame 7 is fixedly connected to the left rail, and the right side of the lower end of the frame 7 is fixedly connected to the right rail. Advantageously, the fixed connection is realized by means of a threaded connection.

The frames 7 are spaced apart from each other in the extending direction of the track 3, and wire rope hooks are provided on the frames 7 located at the tail end and the head end. Thereby, the driving frame is convenient to unfold and fold, and the driving frame and the track move together, so that the movement of the whole folding frame device is realized.

In addition to the head end frame, each frame 7 is provided with a frame support 8 on each of its lower sides, said frame support 8 being slidably supported on the respective rail 3. Thus, the other frames than the head end frame can slide on the guide rail to accommodate the adjustment of the belt length.

The frame support base 8 may take any suitable form and configuration. In an alternative embodiment, the frame support base 8 includes a base plate 81 mounted to the bottom of the frame 7. The base plate 81 is attached to the bottom of the frame 7 by means of screws or welding, for example. The number of the base plates 81 is two, one on the left side and one on the right side. A semicircular sliding sleeve 82 is arranged below the base plate 81, and the semicircular sliding sleeve 82 is matched with the track 3 and is supported on the track in a sliding manner. Advantageously, a lubricant or grease is provided between the semicircular sliding bush 82 and the rail 3.

In order to improve the strength, reinforcing ribs are welded on the base plate 81 and the semicircular sliding sleeve 82.

A link mechanism 6 is provided between the adjacent frames 7, the link mechanism 6 including two intermediate bars 61 and four side bars 62, the two intermediate bars 61 being hinged to each other at the middle, both ends of the intermediate bars 61 being connected to the adjacent frames 7 through the respective side bars 62. As shown, the side bars 62 are hinged at both ends to the respective ends of the intermediate bar and to the adjacent frame.

In a front view, the side rod on the upper side and the side rod on the lower side are arranged symmetrically up and down. Also, the two intermediate bars are bilaterally symmetrical in front view.

The folding type rack device for the belt conveyor can quickly adjust the length and can integrally move, so that the adjustment efficiency is high, and the requirement of integral position adjustment can be well met.

In order to facilitate the movement of the rail, and to support the rail, the folding frame device further comprises a sleeper 4. The sleepers 4 are arranged below the rails 3 and support the rails 3, and the extending direction of the sleepers 4 is perpendicular to the rails 3. The number of the sleepers 4 is set according to the requirement. Advantageously, on both sides of the splicing location, a sleeper is arranged to support the circular tube-shaped sub-rail 31. The arrangement of the sleepers 4 can reduce the influence on the frame device due to uneven ground and settlement.

In order to improve the convenience of installation, the folding rack device further comprises a fixing plate 9, and two ends of the fixing plate 9 are fixedly connected with the two rails 3 respectively so as to keep the two rails 3 parallel to each other and connect the two rails 3 into a whole. After the track rail 3 and the fixing plate 9 are mounted, a frame or the like may be mounted. The installation position and the number of the fixing plates can be set according to requirements. It should be noted that the mounting position of the fixing plate on the rail 3 needs not to interfere with the sliding of the frame 7 on the rail. In one embodiment only one fixing plate is provided, said fixing plate 9 being provided at the trailing end of the track.

In one embodiment, the folding rack apparatus further comprises: the traction steel wire rope (not shown) is connected with the steel wire rope hooks on the frames 7, and the frames 7 are unfolded or folded along the length direction of the track 3 or the track 3 moves in the length direction of the track under the driving of the driving unit (not shown).

Advantageously, adjacent linkage arrangements 6 are staggered in the width direction. That is, one link mechanism is provided on the left side, the next link mechanism 6 is provided on the right side, and the next link mechanism is provided on the right side. Therefore, under the furled state, the mutual interference of adjacent link mechanisms can be avoided. Improving the compactness in the furled state. In other words, the link mechanism 6 is installed inside and outside at intervals to increase the telescopic folding ratio. For example, with such an arrangement, the telescopic folding ratio can be 1: 5.

for example, if a folding rack device requires a telescopic length of 30 meters, the folding ratio is 1: 5 (fully furled length: telescopic length). Thus, the length of the folded machine frame is 6 meters after the folded machine frame is completely folded, and the maximum unfolding length of the folded machine frame needs 36 meters. And the total length of the three front-end fixing frames is not less than 40 m. Before the frame is released, all the parts are concentrated at the front end of the track, and the connecting rod mechanism is folded. When the folding machine frame is moved, the hydraulic motor and the steel wire rope are firstly used for driving the frame and the track to move together through the steel wire rope fixing buckle on the end frame. The folding rack slides on the track in sequence, the tail end rack is fixedly connected with the fixed rack, the middle rack moves along with the track, the contracted connecting rod mechanism is opened, after the tail rack is completely opened, the limiting head sends out an alarm signal, the storage belt is completely released, the storage belt and the rack are required to be stored and supplemented, at the moment, the tail rack is pulled through the steel wire rope, the released connecting rod mechanism is folded, and the fixed rack is additionally arranged in the space. The operation is circulated, and a rack is not required to be added when the tail moves every time.

The utility model discloses a belt conveyor is with folding frame device simple structure, convenient operation, occupation space is little, adapts to the operational environment in the pit.
