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

In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

Referring to the accompanying drawings 1 to 5 of the specification, FIG1 is a schematic diagram of the extended state structure of the retractable frame for the belt conveyor provided in the embodiment of the present application, FIG2 is a schematic diagram of the retracted state structure of the retractable frame for the belt conveyor provided in the embodiment of the present application, FIG3 is a schematic diagram of the partial assembly of the frame and the bridge sliding frame provided in the embodiment of the present application, FIG4 is a schematic diagram of the partial assembly of the frame and the retractable belt roller mechanism provided in the embodiment of the present application, and FIG5 is a side view of the retractable frame for the belt conveyor provided in the embodiment of the present application, including: a driving tail 1, a bridge sliding frame 2, a retractable belt roller mechanism 3 and a mobile frame; one end of the bridge sliding frame 2 is connected to the driving tail 1, and the other end is slidably connected to the inside of the mobile frame through a roller, and the driving tail 1 can drive the bridge sliding frame 2 to move along the length direction of the mobile frame by its own power. The retractable belt roller mechanism 3 is slidably connected inside the mobile frame, and its two ends are respectively connected to the bridge sliding frame 2 and the rear end of the mobile frame. The middle part of the telescopic belt roller mechanism 3 can be telescopic, and the sliding of the bridge sliding frame 2 can drive the telescopic belt roller mechanism 3 to telescope, so as to realize the free movement of the bridge sliding frame 2 in the mobile frame and extend the sliding range of the bridge sliding frame 2. In a single collection operation, under the premise of fixing the mobile frame, the telescopic belt roller mechanism 3 is extended to increase the collection and recovery distance of the bridge sliding frame 2.

The mobile frame can move along its own length direction. Since the bridge sliding frame 2 and the telescopic belt roller mechanism 3 are slidably connected inside, the mobile frame can adjust the position of the bridge sliding frame 2 and the telescopic belt roller mechanism 3 relative to the mobile frame after changing its own position. In this way, the equipment can be mined over a long distance without stopping, greatly improving work efficiency. The overall structure is safe and firm through mechanical connection transmission.

The movement of the above-mentioned mobile frame can be achieved by adding an external mobile structure, which will not be elaborated in this article.

Furthermore, the above-mentioned mobile frame is configured as a step-type mobile frame, comprising: a frame body 4, a lifting cylinder 5, a horizontal displacement cylinder 6 and a supporting sliding shoe 7;

One end of the bridge sliding frame 2 is slidably connected to the bottom surface inside the frame 4, and the telescopic belt roller mechanism 3 is slidably connected to the top surface inside the frame 4; such an arrangement facilitates ensuring that the bridge sliding frame 2 and the telescopic belt roller mechanism 3 move along the length direction of the frame 4.

The lifting cylinder 5 is connected to both ends of the frame 4, and the bottom of the lifting cylinder 5 is slidably connected to the top surface of the support shoe 7 through a pulley and a fixed connecting plate. The horizontal displacement cylinder 6 is installed on the top surface of the support shoe 7, and the horizontal displacement cylinder 6 abuts against the lifting cylinder 5, thereby realizing the horizontal displacement of the lifting cylinder 5.

When the walking movable frame walks forward (the front here refers to the collection direction facing the driving machine tail 1, and correspondingly, the backward movement refers to the recovery direction away from the driving machine tail 1), the lifting cylinders 5 at both ends of the walking movable frame contract, driving the supporting slide shoe 7 to leave the ground, the frame legs 41 support the ground, the horizontal displacement cylinder 6 extends to drive the supporting slide shoe 7 forward, and then the lifting cylinder 5 extends so that the supporting slide shoe 7 supports the ground, and the reciprocating cycle realizes the overall walking forward of the frame 4.

When the walking movable frame moves backward, the lifting cylinder 5 of the walking movable frame extends to lift the frame 4, the horizontal displacement cylinder 6 on the supporting slipper 7 extends, and the frame 4 moves backward. When the horizontal displacement cylinder 6 extends to the limit position, the lifting cylinder 5 contracts to lift the supporting slipper, the frame legs 41 support the ground, the horizontal displacement cylinder 6 on the supporting slipper 7 contracts, and the supporting slipper 7 moves backward.

Furthermore, the lifting cylinders 5 are respectively connected to both sides of the two ends of the frame 4, and the left-right deflection and movement of the frame 4 and its internal structure are controlled by changing the axial deflection angle of the lifting cylinders 5.

The arrangement and use of the above-mentioned lifting cylinder 5 can refer to the existing technology and will not be elaborated in this article.

Furthermore, the telescopic belt roller mechanism 3 comprises: a plurality of suspension rollers and a transmission chain connected between the suspension rollers; the plurality of suspension rollers are arranged along the length direction of the frame 4, and the top of each suspension roller can move along the length direction of the frame 4, and the telescopic movement is achieved by adjusting the spacing between the suspension rollers. The telescopic belt roller mechanism 3 can realize the continuous and uninterrupted transportation of the rollers and the belts thereon during the forward and backward movement of the tail 1 and the forward and backward movement of the frame 4.

One end of the bridge-type sliding frame 2 is connected to a transmission chain, thereby driving the distance adjustment between each suspension roller to achieve the extension and retraction of the telescopic belt roller mechanism.

The arrangement and use of the above-mentioned suspension rollers can be referred to the prior art and will not be elaborated in detail herein.

Furthermore, the driving tail 1 is connected to the bridge-type sliding frame 2 via the dragging oil cylinder 8, which can realize motion transmission and avoid loss of transmission force, and also play a role in adjusting the direction of the bridge-type sliding frame 2.

The arrangement and use of the above-mentioned pulling cylinder 8 can refer to the prior art and will not be elaborated in this article.

Furthermore, the top and bottom surfaces inside the frame 4 are both provided with slide tracks, the slide track on the top surface is used to hang and guide the telescopic belt roller mechanism 3, and the slide track on the bottom surface is used to assemble and guide one end of the bridge-type sliding frame 2.

Furthermore, a belt rack 9 is arranged outside the end of the mobile frame away from the driving machine tail 1, and the belt rack 9 is used to stabilize the installation of the telescopic belt roller mechanism 3. The arrangement and use of the belt rack 9 can refer to the prior art, and will not be elaborated in this article.

During normal forward mining, the tail 1 is driven forward by its own power, and the bridge-type sliding frame 2 is driven forward by the dragging cylinders 8 on both sides, thereby driving the telescopic belt roller frame 3 to extend along the sliding track. When extended to the limit, since the telescopic belt roller frame 3 is less than the length of the mining surface, when the step-type moving frame needs to move forward as a whole, the lifting cylinders 5 at both ends of the step-type moving frame are contracted, driving the supporting sliding shoe 7 off the ground, the frame legs 41 support the ground, the horizontal displacement cylinder 6 extends to drive the supporting sliding shoe 7 forward, and then the lifting cylinder 5 extends so that the supporting sliding shoe 7 supports the ground, and the reciprocating cycle realizes the overall stepping forward of the frame 4. When it is necessary to recover the working face, the driving machine tail 1 can move backward by its own power, thereby driving the bridge sliding frame 2 to compress the telescopic belt roller frame 3 backward. When the telescopic belt roller frame 3 is compressed to the limit position, it is necessary to stop the machine and remove a certain length of the belt frame 13. After meeting the backward requirements of the walking type moving frame, the cylinder of the lifting cylinder 5 device of the walking type moving frame is extended to lift the frame 4, the horizontal displacement cylinder 6 on the supporting slipper 7 is extended, and the frame 4 moves backward. When the horizontal displacement cylinder 6 is extended to the limit position, the lifting cylinder 5 contracts to lift the supporting slipper, the frame leg 41 supports the ground, the horizontal displacement cylinder 6 on the supporting slipper 7 contracts, and the supporting slipper 7 moves backward. The cycle is repeated until the walking type moving frame moves to the back of the belt frame 13, and the backward movement of the frame 4 is realized.

It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
