[0029] This utility model discloses a movable belt conveyor, which improves the conveying capacity of the movable belt conveyor.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-4 As shown, Figure 1 A schematic diagram of the layout structure of the movable belt conveyor provided in this application; Figure 2 for Figure 1 Schematic diagram of the structure of the mid-section of the aircraft head frame; Figure 3 for Figure 1 Schematic diagram of the intermediate frame structure; Figure 4 for Figure 1 A schematic diagram of the structure of a medium-tracked chassis.

[0032] This application provides a movable belt conveyor, including a head frame 1, an intermediate frame 2, and a tail frame 5, as well as traveling rails respectively arranged on the top of the head frame 1, intermediate frame 2, and tail frame 5; a cable reel 3 and a receiving trolley 4 are arranged on the traveling rails; the head frame 1, intermediate frame 2, and tail frame 5 are also equipped with a tracked chassis 6. The head frame 1, intermediate frame 2, and tail frame 5 of the belt conveyor are automatically moved by the tracked chassis 6 set under each frame. A set of traveling rails is set on the upper part of the head frame 1, tail frame 5, and intermediate frame 2, so that the cable reel 3 and the receiving trolley 4 can travel on the traveling rails. By setting the belt conveyor as a self-moving structure driven by the tracked chassis 6, the cable reel 3 and the receiving trolley 4 can move with the tracked double-drum mining machine, electric shovel, crushing station, transfer station, and other mining equipment on the working face, thereby improving the conveying capacity of the movable belt conveyor.

[0033] In a specific embodiment of this case, the head frame 1 includes a head frame body 101, a drive device 102 arranged within the head frame body 101, and a tensioning device 103 connected to the cable reel 3. The head frame 1 is composed of the head frame body 101, the drive device 102, the tensioning device 103, the head frame rails 104, idlers, head funnels, and other components. The head frame body 101 provides space for the drive device 102 and the tensioning device 103, and can provide stable support for the top head frame rails 104 and idlers.

[0034] Meanwhile, by integrating components such as the drive unit 102 and the tensioning device 103 into the head frame 1, they can be moved together as a whole.

[0035] The head frame 101 is also equipped with a head funnel for transferring materials conveyed by the receiving trolley. The head funnel at the head of the head frame 101 facilitates the transfer and conveying of materials transported by the receiving trolley.

[0036] like Figure 5 As shown, Figure 5 The diagram shows the support structure of the intermediate frame for the receiving trolley.

[0037] Furthermore, the head frame 1, intermediate frame 2, and tail frame 5 are all equipped with idlers to support the movement of the receiving trolley 4. Taking the intermediate frame as an example, the idler 203 is arranged on the intermediate frame 2. The receiving trolley 4 includes traveling legs that cooperate with the traveling rails and a carrying cylinder for carrying materials. A traveling roller 401 is installed at the bottom of the carrying cylinder, which cooperates with the idlers on the head frame 1, intermediate frame 2, and tail frame 5 to improve the movement safety of the receiving trolley 4.

[0038] In this application, the intermediate frame 2 includes multiple frames that can be spliced ​​and connected.

[0039] The tail frame 5 includes a tail frame body and a redirecting roller located at the rear of the tail frame body to change the direction of the cable winding drum. The tail frame is supported by the tail frame body, and the traveling rail is the tail frame rail located at the top of the tail frame body. The tail frame is also equipped with a tail redirecting roller, which works with the cable of the cable winding drum to drive the receiving trolley back and forth. At the same time, the tail frame body is equipped with idler rollers that cooperate with the movement of the receiving trolley.

[0040] In one specific embodiment of this case, the tracked chassis 6 includes a connecting beam 601 for supporting the frame and a slewing support device 605 for supporting the connecting beam 601.

[0041] The chassis frame 605 is used to support the slewing support device 605, and the walking tracks 604 are arranged on the chassis frame 606.

[0042] Furthermore, the connecting beam 601 is hinged at its midpoint along its length to the slewing support device 605, which is equipped with two adjusting cylinders 603 for adjusting the height of both ends of the connecting beam 601 along its length. The tracked walking device 6 is suitable for walking in mining road environments. Meanwhile, the movable belt conveyor needs to meet multi-directional walking requirements during its movement. To ensure stable support for the head frame 1, intermediate frame 2, and tail frame 5, a slewing support device 605 is installed between the chassis frame 606 and the connecting beam 601 of the supporting frame, thereby ensuring stable support for the head frame 1, intermediate frame 2, and tail frame 5 during the tracked walking chassis's reversal.

[0043] Meanwhile, to ensure the stability of the inclined bottom surface, a hinged support structure 602 is provided between the connecting beam 601 and the slewing support device 605. The middle part of the connecting beam 601 is hinged to the slewing support device 605. An adjusting cylinder 603 is provided at each end of the connecting beam 601 along its length. By adjusting the extension length of the cylinder 603, the extension height and extension angle of the connecting beam 601 relative to the slewing support device 605 are adjusted, thereby achieving stable support for the frame.

[0044] In this embodiment, the head frame 1, intermediate frame 2, and tail frame 5 are all configured as truss structures. The truss structure has strong load-bearing capacity and can also form internal space to facilitate the arrangement of structures such as drive devices and tensioning devices.

[0045] like Figure 6 As shown, Figure 6 This is a partially enlarged schematic diagram of the connection structure between adjacent frames.

[0046] In a specific embodiment of this case, a frame hinge device 701 is provided between the head frame 1 and the intermediate frame 2, and between the intermediate frame 2 and the tail frame 5, and a turning gap is reserved between adjacent traveling rails.

[0047] Due to the unevenness and undulating terrain of the mining surface, a tracked chassis 6 and an adjusting mechanism for the connecting beam 601 on it are installed to provide stable support structures between the head frame 1 and the intermediate frame 2, and between the intermediate frame 2 and the tail frame 5. Simultaneously, considering the long spans of the head frame 1, intermediate frame 2, and tail frame 5 along the traveling direction of the rails, which could lead to height fluctuations at the frame connection points during travel, frame hinge devices 701 are installed between adjacent head frames 1 and intermediate frames 2, and between intermediate frames 2 and tail frames 5. Specifically, adjacent frame sections are connected by hinge frames and hinge shafts. Tilting gaps are provided between adjacent traveling rails, such as between the head frame rail 702 and the intermediate frame rail 703, and between the intermediate frame rail and the tail frame rail, to prevent rail collisions and interference during hinge structure rotation, and also serve as rail expansion joints.

[0048] In this embodiment, when the automatic relocation belt conveyor is relocated as a whole, the tracked chassis under each head frame, tail frame, and intermediate frame can move simultaneously, and each tracked chassis can also be controlled individually, adjusting in real time according to the overall status of the belt conveyor.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
