Technical Field

[0001] The utility model relates to coal mines and mine transport machinery, in particular to a self-moving walking device of a fully mechanized coal mining and conveying machine. Background Art

[0002] At present, the coal transportation system of the underground fully-mechanized mining face mainly uses supporting equipment such as transfer machines, crushers, and transport belts for coal transportation. Taking a fully-mechanized mining face with a chute length of 1000m as an example, the fixed length of the transfer machine and belt conveyor includes: the fixed length of the belt self-moving machine tail and the transfer machine is about 80m; the fixed part of the belt: including the driving part, tensioning part, unloading part, and hydraulic pump station part is about 40m. Due to the limitation of the fixed length of the transfer machine and belt conveyor during the final mining of the fully-mechanized mining face, the final stop mining distance is about 120m from the transport chute, and the remaining safety coal pillar is greater than the specified value, resulting in a waste of coal resource mining. Utility Model Content

[0003] The utility model provides a self-moving walking device for a coal mine comprehensive mining transfer machine to solve the problem that the coal resource mining is wasted due to the length limitation of the fixed parts above the transfer machine and the belt conveyor during the final mining period of the comprehensive mining working face.

[0007] The supporting part connecting shaft is a pair, which is respectively installed in the middle of each supporting box and parallel to the walking wheel shaft. The supporting part is a pair, and the lower part of the supporting part is rotatably installed on the supporting part connecting shaft, and the device bearing platform is installed on the top of a pair of supporting parts.

[0008] The lower part of the support part is in the shape of an inverted triangle and is located inside the support box, and the upper part is in the shape of a rectangle with the top of the rectangle extending out of the support box; the connecting shaft of the support part is arranged close to the vertex of the inverted triangle.

DETAILED DESCRIPTION

[0018] Embodiment 1 A self-propelled walking device of a coal mine comprehensive mining transfer machine comprises two walking guide rails 8 (the width is greater than that of a scraper conveyor), a support box 3 (the bottom is at a sufficient distance from the ground for arranging a scraper conveyor), and walking wheels 5 installed below the support box 3 for moving on the walking guide rails 8. A support part connecting shaft 4 is horizontally installed on the support box 3, and the support part connecting shaft 4 is perpendicular to the direction of the walking guide rails 8. A support part 2 is rotatably connected to the support part connecting shaft 4, and a device bearing platform 1 located above the support box 3 is installed on the top of the support part 2.

[0019] When used, two walking rails 8 are placed on the outside of the scraper conveyor, and the self-moving walking device of the coal mine fully mechanized mining and loading machine moves on the walking rails through the walking wheels, while not affecting the work of the scraper conveyor (such as Figure 4 As shown in FIG. 1 ), the length of the transport equipment can be effectively shortened; the head of the transfer machine is supported by the device carrying platform 1, and the tail of the transfer machine is supported on the ground, so the transfer machine can maintain balance, and the support part 2 has a certain rotation space, and the support angle can be appropriately adjusted with the head of the transfer machine. The head of the transfer machine is fixed to the device carrying platform.

[0020] Example 2 The support box 3 is a pair, both of which are rectangular in structure, and the lower part of each support box 3 is evenly installed with two running wheels 5 through a running wheel shaft 6, one in front and one behind; a pair of support boxes 3 are respectively movably supported on a pair of running guide rails 8 through the running wheels 5; the running guide rail 8 adopts an I-beam structure; an anti-derail baffle 7 is installed on the side of the two support boxes 3 facing outward (i.e. toward the outside of the running guide rail) corresponding to each running wheel 5; the anti-derail baffle 7 is composed of a vertical section and a horizontal section connected to the vertical section near the bottom, each running wheel shaft 6 extends to the side facing outward (i.e. toward the outside of the running guide rail), the top of the vertical section of the anti-derail baffle 7 is installed on the part extending from the running wheel shaft 6, and the horizontal section is connected to the vertical section and extends from the outside of the I-beam to the bottom of the upper wing plate of the I-beam. The support part connecting shaft 4 is a pair, which is respectively installed in the middle of each support box 3 and parallel to the walking wheel shaft 6. The support part 2 is a pair, and the lower part of the support part 2 is rotatably installed on the support part connecting shaft 4. The device bearing platform 1 is installed on the top of a pair of support parts 2.

[0021] The anti-derail baffle is located on the outside of the I-beam and is stuck under the upper wing plate of the I-beam. The anti-derail baffles of the left and right supporting boxes cooperate with each other to effectively prevent the self-moving walking device from falling off the track.

[0022] Embodiment 3 The lower portion of the support portion 2 is in the shape of an inverted triangle and is located inside the support box 3 , and the upper portion is in the shape of a rectangle with the top of the rectangle extending out of the support box 3 ; the support portion connecting shaft 4 is arranged close to the vertex of the inverted triangle.

[0023] The support part can rotate around the support part connecting axis 4, but because the support part connecting axis 4 is arranged close to the top angle of the inverted triangle, that is, the support part connecting axis 4 is located at the bottom center of the support part, under normal circumstances, the device supporting platform 1 above the support part remains horizontal; in actual applications, it can also appropriately rotate back and forth at a certain angle with the head of the transfer machine in order to adjust to the optimal support position.

[0024] A pin hole is vertically opened on the device carrying platform 1 ( Figure 1 The support frame of the transfer machine head is also provided with a pin hole, and the transfer machine head and the device carrying platform 1 are connected by a pin shaft to prevent relative sliding between the transfer machine head and the device carrying platform.

[0025] The structure of this device is as follows Figure 1 , 2 As shown:

[0026] 1. This device is composed of a device carrying platform 1, a support part 2 and a support box 3 to support the transfer machine;

[0027] 2. The lower part of the support part 2 is connected to the support box 3 through the support part connecting shaft 4, so that the angle between the transfer machine and the walking guide rail 8 can be freely adjusted;

[0028] 3. The lower part of the supporting box 3 is equipped with a walking wheel 5 and a walking wheel shaft 6, which can move on the walking guide rail 8;

[0029] 4. The anti-derail baffle 7 can prevent the device running wheel from falling off the running rail due to deflection.

[0030] Note: The forward moving force of the transfer machine comes from the hydraulic support push cylinder at the end of the comprehensive mining working face.

[0031] Figure 3 , 4 Shown: After the transfer machine is installed on the device, it is used together with the transfer machine and scraper conveyor. Figure 3 It can be seen that the transfer machine head and the device carrying platform are connected through a pin shaft.

[0032] Figure 5The figure shows a schematic diagram of the comparison before and after the installation of the device in the chute transport equipment, where the upper part is before the use of the device, and the lower part is after the use of the device. It can be seen that after the use of the utility model, the length of the entire equipment is reduced (the position of the walking guide rail and the scraper conveyor can overlap), so the stop mining line can be shortened to about 60m, that is, the recovery footage is increased by 60m, which effectively improves the coal recovery rate.
