The embodiment of the utility model provides a with supporting belt conveyor of coal-winning machine with foldable frame device, include with the supporting belt conveyor of coal-winning machine with foldable frame device: a track 2; a plurality of frames 3 and a walking traction gantry crawler 6.

The track 2 is supported on the ground for supporting the machine frame, at least a part of the machine frame.

The track 2 may take any suitable cross-sectional shape, configuration or construction. For example, the cross-sectional shape may be circular or annular; or an i-steel shape, or a rectangular shape, etc. The number of the rails 2 may be one, two or more.

In one embodiment, two rails 2 are used, and the two rails 2 are arranged in parallel to each other, thereby improving the stability of the support.

The length of the track 2 and the distance between the two tracks are set as desired. For example, in one embodiment, the length of the track is 80 meters.

For the convenience of underground arrangement, each track 2 is formed by splicing a plurality of sub-tracks 21 and sub-track clamping plates 22. The length of each sub-rail 21 is set to 6 meters or less, for example. The adjacent sub-rails 21 are connected to each other by sub-rail clips 22 and supported at the connection on the ground by the shoe 1. The skid shoe 1 can reduce the influence on the frame caused by uneven ground and settlement. The sub-rail clamping plates 22 clamp the adjacent sub-rails 21 on the left and right sides and are respectively connected with the sub-rails, thereby achieving connection between the adjacent sub-rails.

The sliding shoes 1 are arranged in pairs at the left and the right, and the two rails 2 are connected into a whole through a cross beam in groups. After the sub-rail 21 and the sub-rail clamping plate 22 are installed, a frame or the like may be installed. It should be noted that the mounting position of the sub-rail clip 22 on the rail 2 needs not to prevent the frame from sliding on the rail.

The number of the racks is set according to needs. The plurality of racks 3 are combined into a folding rack. The plurality of frames 3 are spaced apart from each other in the extending direction of the rail 2, and the entire length of the plurality of frames is folded and unfolded by increasing and decreasing the distance between the adjacent frames.

A conveyor supporting roller 31 is provided at the upper end of each frame 3 for supporting the conveyor. That is, the upper end of each frame 3 is provided with a conveyor belt support for supporting the conveyor belt. The specific shape, structure, number, arrangement and the like of the conveyor belt supports can be set as required.

Adjacent frames 3 are interconnected by a linkage 7. Thus, the synchronous expansion or contraction of all the racks is realized. The specific shape and structure of the frame 3 are not limited to the illustrated embodiment, but may take any suitable shape and structure.

The plurality of frames 3 includes a head end frame 4, a tail end frame 8, and an intermediate frame 9 between the head end frame 4 and the tail end frame 8. The head end shelf 4 and the tail end shelf 8 are relative. For example, the rack in the adjustment direction may be referred to as a head end rack.

The head end frame 4 and the intermediate frame are arranged to be able to slide on the rail 2, it being noted that the sliding resistance can be reduced by arranging rollers between the frame and the rail. In addition to the front end frame 4, each of the other frames 3 is provided on both sides of the lower end thereof with a frame support base plate 33, the frame support base plates 33 being rollingly supported on the corresponding rails 2 by the contour wheels 35. The profile wheel 35 is provided with projecting stops on the left and right sides, which are adapted to cooperate with the left and right profiles of the rail, thereby limiting the left and right relative position of the profile wheel with respect to the rail.

The end bracket 8 is fixed relative to the track 2. Thus, the tail end frame moves integrally with the rail. A connecting part is arranged on the tail end frame 8 and/or the track 2, and the connecting part is suitable for being connected with a driving unit so that the driving unit can drive the tail end frame 8 and the track 2 to move. The drive unit may take any suitable arrangement or configuration. The adjustment of the overall length is achieved by relative movement between the head end frame 4, the intermediate frame 9 and the tail end frame 8.

The link mechanism 7 between the adjacent frames may take any suitable form and configuration as long as the contraction and expansion between the adjacent frames can be achieved, and is not limited to the illustrated embodiment. In the illustrated embodiment, the linkage 7 between adjacent frames comprises, for example, four intermediate bars 71 and four end bars 72. Every two middle rods 71 form a group of cross rods, the middle parts (middle cross hinge points) of the two middle rods 71 of one group of cross rods are hinged with each other, the adjacent end parts of the two groups of cross rods are hinged with each other, the far end parts of the two groups of cross rods are hinged to end rods 72, and the end rods 72 are hinged to the rack. That is, both ends of each end rod 72 are respectively hinged with the corresponding end of one intermediate rod and the adjacent frame.

In order to limit the maximum extension of the frame, the linkage may also be provided with a limit stop 73. The two ends of the limiting member 73 are respectively connected with the middle cross hinge points of the two sets of cross rods to limit the maximum unfolding degree of the rack. The limiting member 73 can be a limiting telescopic rod and a limiting rope. The maximum length of the limiting telescopic rod or the straightening length of the limiting rope limits the maximum unfolding degree of the rack, and the limitation of the maximum distance between adjacent racks is realized.

In one embodiment, each of the racks 3 includes a housing body 32, and a base plate 33 is provided at the bottom of the housing body 32. The base plate 33 may take any suitable form and construction. The base plate 33 is connected to the bottom of the housing body 34 by means of screws or welding. The number of the base plates 33 is two, one on the left side and one on the right side. In an alternative embodiment, profile wheels 35 are arranged below the base plate 33, and the profile wheels 35 are engaged with the track rail 2 and are supported on the track rail 2 in a rolling manner. The cross section of the rail 2 is, for example, i-beam shaped, the latter being rectangular frame shaped. The frame 4 at the head end is supported at the lower end at both sides and is fixedly connected to the two rails 2 by frame wheeled support base plates 33, respectively. In order to improve the strength, reinforcing ribs are welded on the base plate 33 and the wheel seat of the special-shaped wheel 35.

The walking traction gantry crawler device 6 is spanned above the frame 3. The walking traction gantry crawler device 6 is connected with the head end frame 4 and can pull the head end frame 4 to slide on the track 2. For example, the plurality of frames 3 are unfolded, that is, the length of the belt conveyor is lengthened; or the plurality of frames are folded, namely the length of the belt conveyor is shortened.

Specifically, the walking traction gantry crawler device 6 comprises a gantry 63 and a walking crawler 61 driven by a hydraulic power source.

The walking crawler 61 walks on the ground on two sides of the frame 3, and simultaneously drives the head end frame 4 to move on the track 2 through the universal joint 62, so that the frame 3 is unfolded.

In one embodiment, the walking traction gantry crawler 6 is used to achieve the unfolding of the frame and the drive unit is used to achieve the folding of the frame. More specifically, in the case of backward mining, when it is desired to shorten the length of the rack, the drive unit gradually folds the rack so that the tail end frame 8 and the rail move towards the direction of the proximity head end frame 4, i.e. the tail end frame retracts, for example, until the folding rack reaches a minimum length, but may, of course, be only partially folded. In case of further shortening the length of the belt conveyor, the gantry crawler 6 is dragged by the user to make the head end frame 4 slide on the track 2 and move in a direction away from the tail end frame 8, i.e. the head end frame retreats (note that, at this time, part of the fixing frame needs to be removed). For example, the folding chassis may be made to expand to a maximum length, or may be partially expanded.

In other words, when the traveling crawler 61 travels, the front fixed frame is removed, and the traveling crawler 61 moves the head end frame 4 and the folding frame 3 connected thereto on the lower rail 2 via the universal connecting rod 62, and in turn opens the folding frame 3.

Retreat mining is a common stoping method in the normal stoping process of coal mines. During backward mining, the advancing direction of the working face faces the auxiliary transportation main roadway, and the air flow of the working face does not pass through the goaf, so that fire prevention and extinguishing of the goaf are facilitated. More specifically, after the stage haulage drift is tunneled to the boundary of the well field, the ore blocks from the boundary of the well field are recovered towards the main well or the main drift.

In another embodiment, the walking traction gantry crawler assembly 6 is used to effect the furling of the frame and the drive unit is used to effect the unfolding of the frame.

As previously mentioned, the drive unit may take any suitable arrangement or configuration. In one embodiment, the drive unit comprises a hydraulic winch 11 and a traction rope 111. The hydraulic winch 11 is arranged on the walking traction gantry crawler device 6, one end of the traction rope 111 is wound on a winch drum of the hydraulic winch 11, and the other end of the traction rope 111 is connected with the tail end frame 8 and/or the track 2 so as to drive the tail end frame 8 and the track 2 to move. Thereby, the folding or unfolding of the plurality of racks 3 is achieved.

The hauling cable 111 is a double-cable, the other end of the hauling cable 111 is connected with a hauling cable hook arranged on the tail end frame 8 through a balance oil cylinder 112, and under the driving of the driving unit, the plurality of frames 3 are unfolded or folded along the length direction of the track 2, or the track 2 moves along the length direction of the track.

In this embodiment, the end bracket 8 is fixedly connected to the track 2 to form a single unit. The left side and the right side of the tail end frame 8 are respectively provided with a balance oil cylinder with a connecting ring (an oil cylinder lug ring) so as to ensure that the trace asynchronism of a traction rope is compensated when the double-rope traction of the hydraulic winch is carried out, and the tail end frame 8 and the track 2 move forwards along the central line of the belt conveyor. Meanwhile, the machine frame supported on the track 2 is blocked by the fixed belt machine frame or the head end frame, and the machine frame 3 is contracted on the track in sequence until all the machine frames are closed. The balancing cylinders on the left and right sides are communicated with each other, thereby ensuring that the same or basically the same traction force is applied on the two sides. The oil cylinder earrings are connected with the traction ropes.

And guide plates are arranged on two sides of the front end of the track and are used for positioning at the inner side of the fixed rack when the track moves forwards so as to prevent deviation.

The tail end frame 8 and the track 2 are fixed when the walking crawler 61 walks, and the head end frame 4 and the frame 3 move and stretch on the track 2. After the walking crawler 61 is in place, (the maximum unfolding state) and the belt conveyor is contracted in the length direction, the tail end frame 8 and the track 2 are dragged to move by the hydraulic winch 11 through the traction rope 111 and the balance oil cylinder 112, the machine frame 3 is blocked by the front end fixed belt machine frame to be sequentially closed, the energy accumulator implements consistent tension of the two balance oil cylinders by using a tee joint so as to ensure that the machine frame moves along the central line of the belt conveyor, and the walking crawler 61 and the hydraulic winch mutually act to realize the opening and closing of the folding machine frame.

In order to facilitate the installation and movement of the relevant equipment, an equipment platform 10 is arranged on the portal frame 63 of the walking traction portal crawler device 6. And a hydraulic pump station 12 and a hydraulic winch 11 are arranged on the equipment platform 10.

The equipment platform 10 is further provided with an electric control box 12 with remote control and remote control functions to control the walking crawler 61 and the hydraulic winch 11.

The equipment platform 10 is further provided with a video monitoring system for providing image monitoring for an operator.
