Description

Technical Field

[0001] The utility model belongs to the technical field of mine support, in particular to a coal guiding device and a chute self-moving unit bracket. Background Art

[0002] When the chute self-moving unit support is pulled, the base of the chute self-moving unit support slides on the ground of the tunnel, and a lot of coal slime and rocks will accumulate in front of the base, increasing the difficulty of pulling the chute self-moving unit support. Especially when the chute self-moving unit support passes through the water accumulation and bottom coal area, the accumulation of the accumulated coal slime and rocks is particularly serious, and even buries the entire base. The coal slime must be cleaned before pulling the chute self-moving unit support, which increases the labor intensity of employees. In addition, too much coal slime is accumulated on the base of the chute self-moving unit support, which will affect the support pipeline, increase the failure rate of the hydraulic system, and increase the damage rate of the push jack and the connector, posing a greater safety risk. The coal slime accumulation on the base will also affect the cross-section of the tunnel and affect the normal passage of employees.

[0003] Based on this, the existing technology needs to be further developed. Utility Model Content

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0020] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0021] According to an embodiment of the utility model, a coal guiding device is provided. Figure 1 and Figure 2 , comprising a coal guiding device, including a bottom plate 1, a guide plate 2, a first baffle 3 and a second baffle 4, the first baffle 3 and the second baffle 4 are respectively located on opposite sides of the bottom plate 1, and the first baffle 3 and the second baffle 4 are both connected to the bottom plate 1, the two ends of the guide plate 2 are respectively connected to the first end of the first baffle 3 and the first end of the second baffle 4, the bottom of the guide plate 2 is connected to the edge of the bottom plate 1, the angle between the guide plate 2 and the bottom plate 1 is not less than 90°, and the second end of the first baffle 3, the second end of the second baffle 4 and the end of the bottom plate 1 away from the guide plate 2 form a channel 5 for installing a self-moving bracket unit 11.

[0022] It should be noted that the coal guiding device is installed below the self-moving support unit 11. When the self-moving support unit 11 moves forward, the bottom plate 1 in the coal guiding device slides on the ground of the tunnel, and the floating coal and rocks on the surface are arched. The arched floating coal and rocks are diverted to the two sides of the guide plate 2 under the action of the guide plate 2, reducing the difficulty of pulling and moving the self-moving support unit 11. The first baffle 3 and the second baffle 4 further block the floating coal and rocks diverted to the two sides to prevent the floating coal and rocks from accumulating on the base 12 of the self-moving support unit 11; the angle between the guide plate 2 and the bottom plate 1 is not less than 90°, which can prevent the floating coal and rocks from passing over the guide plate 2 along the surface of the guide plate 2 and then covering the base 12 of the self-moving support unit 11, thereby reducing the amount of coal slime cleaning and reducing the labor intensity of employees.

[0023] In the coal guiding device of this embodiment, the angle between the guide plate 2 and the bottom plate 1 is set to range from 110° to 150°.

[0024] It should be noted that when the angle between the guide plate 2 and the bottom plate 1 is greater than 150°, the angle between the guide plate 2 and the ground is too small, and floating coal and rocks are accumulated between the guide plate 2 and the ground, hindering the normal movement of the self-moving support unit 11; when the angle between the guide plate 2 and the bottom plate 1 is less than 110°, the inclination angle of the guide plate 2 is too small to play a good diversion effect, and floating coal and rocks are easy to accumulate in front of the guide plate 2, and then go over the guide plate 2 to cover the base 12 of the self-moving support unit 11. Preferably, the angle between the guide plate 2 and the bottom plate 1 is set to 145°, which can not only play a good diversion effect, but also will not hinder the normal movement of the self-moving support unit 11.

[0025] In the coal guiding device of the present embodiment, the connection between the guide plate 2 and the bottom plate 1 is rounded. On the one hand, it helps the guide plate 2 to divert the flow more smoothly; on the other hand, it avoids stress concentration at the connection to cause bumps on the guide plate 2, thereby increasing the service life of the coal guiding device; at the same time, it can also avoid arching up too much floating coal and rock, reduce the impact on the cross-section of the tunnel, and avoid affecting the normal passage of employees.

[0026] In the coal guiding device of the present embodiment, a clearance hole 6 is provided on the guide plate 2 for the connecting end of the push jack to pass through.

[0027] It should be noted that the push jack is used to connect the two front and rear self-moving bracket units 11. The connecting end of the push jack passes through the clearance hole 6 and is connected to the base 12 of the self-moving bracket unit 11 to prevent damage to the push jack and improve the service life of the push jack.

[0028] In the coal guiding device of the present embodiment, mounting holes 7 for fasteners to pass through are provided on the first baffle plate 3 and the second baffle plate 4 to connect the coal guiding device and the self-moving support unit 11 .

[0029] It should be noted that the self-moving support unit 11 and the coal guiding device are detachably connected, so that the self-moving support unit 11 or the coal guiding device can be replaced separately, thereby reducing the replacement cost.

[0030] In the coal guiding device of this embodiment, a lifting hole 8 is provided on the guide plate 2, and / or the first baffle plate 3, and / or the second baffle plate 4. Preferably, a plurality of lifting holes 8 are provided to ensure stability during lifting.

[0031] It should be noted that the lifting hole 8 is provided to provide a connection point for the lifting equipment to prevent the coal guide device from falling off during the lifting process due to loose connection, so as to facilitate the smooth and safe lifting of the coal guide device.

[0032] Specifically, the bottom plate 1, the guide plate 2, the first baffle plate 3 and the second baffle plate 4 are all made of steel plates to improve the strength and durability of the coal guiding device.

[0033] In the coal guiding device of this embodiment, the bottom plate 1, the diversion plate 2, the first baffle 3 and the second baffle 4 are integrally formed, which improves the integrity of the coal guiding device, enables it to withstand greater external forces, and is convenient for processing.

[0034] According to an embodiment of the present invention, a gob-side self-shifting unit support is provided. Please refer to Figure 1 and Figure 2 , which includes a self-shifting support unit 11 and the above-mentioned coal guiding device. The self-shifting support unit 11 includes a base 12 and a telescopic mechanism 13 connected to the base 12. A connection hole for connecting the coal guiding device is provided on the base 12. The connection hole is disposed opposite to the mounting hole 7. A connection seat 14 for connecting a pushing jack is provided on the base 12.

[0035] It should be noted that by providing the coal guiding device, the base 12 of the self-shifting support unit 11 is effectively prevented from being covered by coal slime, and the difficulty of pulling the gob-side self-shifting unit support is avoided. The coal guiding device has a good on-site application effect. Especially when passing through low-lying points, muddy sections and sections with remaining bottom coal in the roadway, the coal guiding device effectively reduces the amount of coal slime deposition on the base 12 of the self-shifting support unit 11, reduces the cleaning difficulty, reduces the labor intensity of workers, and reduces the pulling difficulty of the gob-side self-shifting unit support.

[0036] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention, and the scope of implementation of the present invention cannot be limited. That is, all equal changes and modifications made according to the scope of this application should still fall within the scope covered by the present invention.
