Description

Technical Field

[0001] This utility model relates to the field of coal mining machinery technology, specifically to a conveyor with passive folding outriggers and a coal sweeping system for the conveyor. Background Technology

[0002] Belt conveyors are the primary transportation equipment in coal mine roadways, playing an irreplaceable role in coal production. However, during coal transport, high coal moisture content, large transport volumes, or belt misalignment often result in large amounts of coal falling onto the sides and bottom of the conveyor, leading to a waste of coal resources.

[0003] There is no dedicated equipment for cleaning up coal falling from the bottom of the conveyor. Currently, the usual practice is to first stop the belt conveyor, and then manually use shovels to clear the coal falling from the bottom of the belt conveyor to the side before loading it back onto the belt conveyor.

[0004] Therefore, the existing bottom coal cleaning method has a series of problems, including high manpower, high labor intensity, low efficiency, and potential safety hazards.

[0005] The reason for this is that the belt conveyor has a long span and requires outriggers to support the main structure. When cleaning equipment is used, the outriggers can easily block the walking space, making the entire cleaning process unsustainable. This is the main reason that restricts the entry of cleaning equipment.

[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of the existing technology by providing a conveyor and a coal sweeping system with passively folding outriggers that allow a sweeper to pass smoothly.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a conveyor with passively folding legs, including a conveyor support and several leg assemblies, wherein several of the leg assemblies are arranged below the conveyor support. The outrigger assembly includes a connecting seat, a clamping plate, an outrigger column, and a crossbeam. The connecting seats are fixed in pairs to both sides of the conveyor bracket, and the clamping plate is fixed to the lower end of each connecting seat. The card plate is provided with an upward-facing arc-shaped elongated hole, and a cylindrical locking position is provided at the center of the arc-shaped elongated hole. An oblong hole is provided on the card plate above the arc-shaped elongated hole, and the oblong hole is vertically positioned and located directly above the cylindrical locking position. The support columns are installed at both ends of the crossbeam to form an H-shaped frame. The inner end of each support column is provided with a first pin and a second pin. The first pin is inserted into the waist-shaped hole of the corresponding side plate, and the second pin is slidably installed in the arc-shaped elongated hole of the corresponding side plate. When the support column is perpendicular to the conveyor bracket and supported on the ground, the second pin is engaged in the locking hole and the first pin is located in the upper half of the waist-shaped hole, forming a support locking structure. When the support column is perpendicular to the conveyor support and off the ground, the second pin falls into the arc-shaped elongated hole, the first pin is located in the lower half of the waist-shaped hole, and the support column can swing around the first pin.

[0009] This utility model utilizes the sweeping action of the sweeping equipment. When the sweeping equipment passes the support leg assembly, the support leg assembly is lifted up and folded up as the sweeping equipment passes through using its hinge structure. This solves the problem of space obstructing the forward movement of the sweeping equipment in the traditional solution, where the space under the conveyor support frame blocks the movement of the sweeping equipment.

[0010] Based on the above, the conveyor support includes several intermediate frames and several connecting components, with adjacent intermediate frames connected as a whole by the connecting components.

[0011] Its advantage is that the conveyor support is connected by an assembly structure, so when the current structure is lifted, the impact on the structure of other areas at both ends is relatively smaller.

[0012] Based on the above, the connecting seat is a common structure of the connecting components. The connecting seat is a channel steel, and the bottom of the channel steel is provided with mounting holes. The connecting seat is installed on the intermediate frame by bolts.

[0013] Its advantages are: fewer overall structural components and a simpler structure.

[0014] Based on the above, the main body area of ​​the conveyor support is used to install the conveyor belt assembly.

[0015] The conveyor belt is only installed in the main area; other structures are mainly for passage purposes.

[0016] A conveyor coal cleaning system includes a sweeper and a conveyor with passive folding outriggers; The sweeper moves entirely beneath the conveyor support frame; The top of the sweeper is equipped with two rows of top wheels for lifting a local area of ​​the conveyor support. The front end of the sweeper abuts against the support column or crossbeam during travel, which is used to lift the support column and crossbeam as a whole and rotate them around the first pin shaft so that the sweeper can pass.

[0017] The sweeper in this solution is equipped with top wheels, which reduce resistance and make the movement smoother.

[0018] Based on the above, the sweeper is a tracked sweeper.

[0019] It can meet the passage requirements of complex underground road surfaces.

[0020] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model modifies the support and leg structure of the conveyor belt. The leg is designed to form a self-locking structure when it lands, which can maintain stable support. When it is lifted, it forms a swing structure that can rotate around the second pin. During the forward movement of the sweeper, it is passively folded up, freeing up the forward movement space of the sweeper. This ensures that there are no obstacles when the sweeper is cleaning up fallen coal, solving the problem of the traditional conveyor legs blocking the forward movement space.

[0026] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0027] Example 1 like Figures 1-4 As shown, a conveyor with passively folding legs includes a conveyor support 1 and a plurality of leg assemblies 2, wherein the plurality of leg assemblies 2 are arranged below the conveyor support 1, and the main body area of ​​the conveyor support is used to install conveyor belt assemblies.

[0028] In this embodiment, the conveyor support 1 is also modified to be a support connected by several intermediate frames 3. Adjacent intermediate frames 3 are connected by connecting seats 101. The connecting seats 101 are groove-shaped structures with mounting holes on the groove walls and bottom. They are locked to the intermediate frames 3 by bolts to achieve the connection and fixation of the intermediate frames. The purpose of this design is that when the sweeper passes by, it can lift the connection position of the adjacent intermediate frames 3. Because the intermediate frames 3 are discontinuous structures, the slight local deformation at the connecting seats 101 during the lifting process can reduce the load requirement of the lifting support. At the same time, the slight deformation will not cause the overall stability of the conveyor support 1 to decrease.

[0029] A retaining plate 102 is fixed below the connecting seat 101. The retaining plate 102 is an important structure in the support leg assembly 2. The retaining plate 102 is provided with an arc-shaped elongated hole 103 with the opening facing upward. A cylindrical retaining position 104 is provided at the center of the arc-shaped elongated hole. An oblong hole 105 is provided on the retaining plate above the arc-shaped elongated hole 103. The oblong hole 105 is vertically arranged and located directly above the cylindrical retaining position 104.

[0030] The support leg assembly 2 also includes a support leg column 203 and a crossbeam 204. The connecting seats 101 are fixed in pairs on both sides of the conveyor bracket 1, and the lower end of each connecting seat 101 is fixed with the card plate 102.

[0031] The support column 203 is installed at both ends of the horizontal beam 204 to form an H-shaped frame. The inner end of each support column 203 is provided with a first pin 201 and a second pin 202. The first pin 201 is inserted into the waist-shaped hole 105 of the corresponding side plate, and the second pin 202 is slidably installed in the arc-shaped elongated hole 103 of the corresponding side plate.

[0032] Working principle explanation: In this embodiment, the two support columns 203 in the same group are connected as one unit by the crossbeam 204 to form a stable support structure. Under normal conditions, the support columns 203 are supported on the ground, the first pin 201 enters the upper part of the waist-shaped hole 105, and the second pin 202 enters the cylindrical locking position 104. At this time, the support columns 203 are locked, forming a stable support for the conveyor bracket 1.

[0033] When the sweeper 4 is cleaning the space under the conveyor, the sweeper lifts up part of the conveyor support 1 during its movement. The support column 203 of the lifted part moves down a short distance under its own weight. The first pin 201 enters the lower half of the waist-shaped hole 105, and the second pin 202 enters the arc-shaped elongated hole 105. The support column 203 is unlocked and can rotate around the first pin 201.

[0034] As the sweeper moves forward, the outrigger column 203 or the crossbeam 204 is lifted and rotated at a certain angle to allow the sweeper 4 to pass. After the sweeper passes, the outrigger column 203 returns to its original position under the action of gravity. After the sweeper moves away, the outrigger column 203 falls to the ground, the first pin 201 re-enters the upper part of the waist-shaped hole, and the second pin 202 enters the cylindrical locking position 104 and is locked again.

[0035] Example 2 like Figure 1 and Figure 2 As shown, a conveyor coal cleaning system includes a sweeper 4 and a conveyor with passive folding legs.

[0036] The sweeper 4 travels entirely beneath the conveyor support 1.

[0037] The top of the sweeper 4 is provided with two rows of top wheels 401, which are used to lift a local area of ​​the conveyor support 1. The width of the two rows of top wheels 401 is equivalent to the width of the intermediate frame conveyed to the support 1.

[0038] The front end of the sweeper 4 abuts against the support column or crossbeam during movement, which is used to lift the support column and crossbeam as a whole and rotate them around the first pin shaft so that the sweeper can pass. For ease of movement, the sweeper 4 is a tracked sweeper.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
