Description

Technical Field

[0001] The invention relates to the technical field of raw coal transportation and transfer, and in particular to a conveying frame for efficient vertical transportation and transfer of raw coal in coal mines. Background Art

[0002] Raw coal in coal mines refers to the coal that is directly mined from the coal seam during the underground mining process of coal mines and has not yet undergone any processing. The space underground in coal mines is limited. In order to reduce the occupation of horizontal space, it is necessary to use vertical conveyors to transport raw coal, so as to make full use of vertical space and provide continuous material transportation to improve overall production efficiency. When the vertical conveyor transfers the raw coal, in order to prevent the raw coal from leaking during the vertical transportation process and ensure that the coal can be safely and completely transported from underground to the ground, it is necessary to use a conveyor frame to load the raw coal during transfer to reduce the direct wear of coal blocks on the conveying equipment, extend the service life of the equipment, and reduce maintenance costs.

[0003] However, the conveyor frames currently used in vertical conveyors have the following disadvantages: 1. One-piece conveyor frames are usually used to carry raw coal. Although the one-piece conveyor frames can be used quickly, they take up a lot of space when stacked and stored. Therefore, such conveyor frames cannot be placed in large quantities in coal mines with limited space. As a result, during the transportation process of the vertical conveyor, the conveyor frames need to wait until the previous set of conveyor frames have completed transferring the raw coal before they can be used again, which reduces the efficiency of transferring raw coal and affects the continuity of the entire coal mine production; 2. When the vertical conveyor transports the conveyor frame, the conveyor frame is not effectively limited and fixed, which can easily cause the conveyor frame to tilt, flip or fall off during transportation, causing serious safety accidents, and unstable conveyor frames will hit or wear the vertical conveyor, thereby shortening the service life of the vertical conveyor. Summary of the invention

[0031] See also Figure 1 and Figure 2 The bearing part 41 includes a bearing cross plate 411, bearing rollers 412 and a triangular baffle 413. The bearing cross plate 411 is fixedly installed at the front end of the moving end of the vertical conveyor 1.

The upper ends of the bearing rollers 412 at the left and right ends are fixedly installed with triangular baffles 413.

[0032] See also Figure 3 , Figure 4 and Figure 5The support portion 51 includes a side baffle 511 and an isosceles triangular bottom plate 512. Four isosceles triangular bottom plates 512 are placed above a number of bearing rollers 412. The four isosceles triangular bottom plates 512 are combined to form a rectangular plate structure. One side wall of the isosceles triangular bottom plates 512 that are away from each other is hinged with a side baffle 511. A telescopic rubber baffle for blocking raw coal is arranged between the side baffle 511 and the isosceles triangular bottom plate 512. A groove for inserting the telescopic rubber baffle is arranged between adjacent side baffles 511 (not shown in the figure).

[0033] See also Figure 3 , Figure 4 and Figure 5 The docking portion 52 includes a docking frame 521 and a docking rod 522. The adjacent side baffles 511 that are close to each other are fixedly installed with docking frames 521 that are distributed up and down and docked with each other. The adjacent docking frames 521 that are distributed up and down are commonly inserted with docking rods 522. The upper end of the docking rod 522 is provided with a round boss for limiting its position.

[0034] See also Figure 3 , Figure 4 and Figure 5 The mating portion 53 includes a mating socket 531, a first plug rod 532 and a second plug rod 533. The isosceles triangle bottom plate 512 is provided with a mating socket 531 on a vertical line thereof, and the opening directions of the mating socket 531 are opposite to each other. The front and rear isosceles triangle bottom plates 512 are commonly connected with the first plug rod 532 located in the corresponding mating socket 531, and a through hole is provided at the center of the first plug rod 532. The left and right isosceles triangle bottom plates 512 are commonly connected with the second plug rod 533. The second plug rod 533 passes through the right mating socket 531 and the through hole and is inserted into the left mating socket 531. The first plug rod 532 and the second plug rod 533 form a cross-shaped structure.

[0035] See also Figure 3 and Figure 4 The clamping portion 54 includes a clamping block 541 and a clamping slot 542. The front and rear ends of the first plug rod 532 and the left and right ends of the second plug rod 533 are clamped with a clamping block 541. The clamping block 541 is composed of an upper triangular plate and a lower rectangular plate. The side baffle 511 is provided with a clamping slot 542 that cooperates with the clamping block 541.

[0036] During specific work, when it is necessary to use a conveyor frame to load raw coal, the workers first manually lay the four isosceles triangle bottom plates 512 flat on the ground and arrange the four isosceles triangle bottom plates 512 into a square. Then, one of the side baffles 511 is flipped upward ninety degrees with the hinge point as the center, and the same operation is performed to form a frame structure with the other three side baffles 511. At this time, the bottom plate composed of the four side baffles 511 and the four isosceles triangle bottom plates 512 below constitutes a conveyor frame.

[0037] In the process of flipping the side baffles 511, the docking frames 521 between adjacent side baffles 511 are docked with each other. After the docking frames 521 are docked, the docking rods 522 are inserted from the top docking frame 521 so that the docking rods 522 lock the adjacent side baffles 511. Subsequently, the insertion of the other four docking rods 522 is completed in the same manner as above, thereby completing the fixation of the four side baffles 511.

[0038] Next, first pass the first insertion rod 532 through the matching sockets 531 on the two isosceles triangle bottom plates 512 on the front and rear sides, and then insert the second insertion rod 533 into the matching socket 531 on the left side, so that it passes through the through hole on the first insertion rod 532 and then is inserted into the matching socket 531 on the right side. In this way, the first insertion rod 532 and the second insertion rod 533 form a cross-shaped structure to fix the bottom plate composed of four isosceles triangle bottom plates 512.

[0039] Subsequently, the connecting block 541 is respectively connected to the two ends of the first plug rod 532 and the second plug rod 533, and the connecting block 541 is respectively inserted into the corresponding slot 542, so that when the bottom plate composed of the four isosceles triangle bottom plates 512 bears the force of the raw coal, the four side baffles 511 can provide support for it, thereby completing the assembly of the conveying frame, which can be modularly and quickly assembled into a conveying frame for loading raw coal, allowing the conveying frame to be disassembled and stored when not in use, greatly saving the limited space underground, and being able to store more conveying frame components, thereby improving the overall transportation capacity.

[0040] See also Figure 3 and Figure 6 The positioning portion 61 includes a right-angle block 611, a limit stop block 612 and a slot 613. The upper ends of adjacent side baffles 511 are commonly provided with a right-angle block 611. The lower end surface of the right-angle block 611 is fixedly provided with a limit stop block 612 for limiting the position of the corresponding adjacent side baffle 511. The lower end surface of the right-angle block 611 is provided with a slot 613 for mating with the upper end of the corresponding docking rod 522.

[0041] See also Figure 3 , Figure 5 and Figure 6 The plug-in portion 62 includes a triangular block 621, a plug-in rod 622, a connecting cross plate 623 and a positioning hole 624. The triangular block 621 is fixedly installed at one end of the right-angle block 611 that is close to each other. The lower end of the triangular block 621 is fixedly installed with a plug-in rod 622 that is symmetrical about the contact surface of the corresponding adjacent isosceles triangle bottom plate 512. The symmetrical plug-in rods 622 are jointly fixedly installed with a connecting cross plate 623. The isosceles triangle bottom plate 512 is penetrated with a positioning hole 624 that cooperates with the lower end of the corresponding plug-in rod 622 for plugging.

[0042] During specific operation, after the transfer mechanism 5 is assembled, the right-angle block 611 is placed at the upper end of the right angle formed by a group of adjacent side baffles 511, and then the right-angle block 611 is pressed downward so that the limiting stop block 612 can simultaneously limit the adjacent side baffles 511. At the same time, the upper end of the corresponding docking rod 522 will be inserted into the slot 613, thereby preventing the docking rod 522 from moving up and down. Then, the same operation is performed to complete the fixation of the other three right angles, thereby completing the first fixation of the conveying frame.

[0043] During the downward movement of the right-angle block 611, the plug-in rod 622 will be inserted into the corresponding positioning hole 624. At this time, a group of symmetrical plug-in rods 622 will re-fix the corresponding group of adjacent isosceles triangle bottom plates 512, thereby using double fixation to ensure the structural stability of the conveying frame, further reducing the risk of shaking and deformation during transportation. After the conveying frame is loaded with raw coal, the downward gravity of the raw coal will give downward pressure to the connecting cross plate 623, so that the right-angle block 611 is always attached to the upper end of the side baffle 511.

[0044] See also Figure 1 and Figure 2 The limiting portion 42 includes a limiting slot 421, a spring rod 422 and a slider 423. Except for the front end of the outer ring wall of the leftmost and rightmost load-bearing rollers 412, a limiting slot 421 is opened, and a slider 423 is slidably installed in the limiting slot 421. A spring rod 422 is fixedly installed between the slider 423 and the limiting slot 421. A right-angled triangle with an inclined surface facing backward is arranged on the upper end of the slider 423.

[0045] During specific operation, after the transfer mechanism 5 and the fixing mechanism 6 cooperate to form a conveying frame, the raw coal can be loaded into the conveying frame, and then the feed roller 2 is used to transport the conveying frame loaded with the raw coal. When the feed roller 2 transports the conveying frame to the position of the bearing cross plate 411, the vertical conveyor 1 will rise with the bearing cross plate 411, and then rise with the bearing roller 412. At this time, the triangular baffles 413 on both sides will limit the position of the conveying frame.

[0046] During the rising process of the supporting roller 412, the upper end of the right triangle of the slider 423 will first contact the front end surface of the isosceles triangle bottom plate 512, and as the supporting roller 412 continues to rise, the front end of the isosceles triangle bottom plate 512 will squeeze the slider 423 forward, and when the front end surface of the isosceles triangle bottom plate 512 contacts the vertical section of the slider 423, under the action of the spring rod 422, a number of sliders 423 will limit and fix the position of the conveying frame, and when reaching the position of the discharge roller 3, the conveying frame will be placed above the discharge roller 3, and the supporting roller 412 will continue to descend, causing the conveying frame to separate from a number of sliders 423, so that the conveying frame can be transported outward through the discharge roller 3, thereby completing the transfer of the conveying frame, thereby adaptively limiting the conveying frame when transferring it, ensuring that the conveying frame can be firmly fixed under various conditions, and reducing the friction and collision between the conveying frame and the vertical conveyor 1.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
