Description

Technical Field

[0001] This utility model relates to the field of roadway support devices, specifically, to a simple integrated support and transportation device for transport roadways. Background Technology

[0002] The reinforcement of transport roadways in fully mechanized mining and longwall mining faces (including end supports and advance supports) has always been a crucial factor affecting the safe and efficient mining of coal. The "Coal Mine Safety Regulations" stipulate that reinforcement support must be provided within 20 meters of the connection between all safety exits of the mining face and the roadway. Within the required reinforcement support range for transport roadways, transport equipment such as transfer conveyors, crushers, self-moving mechanisms for transfer conveyors, self-moving tail sections of belt conveyors, and belt conveyors are typically arranged. Currently, existing support equipment (end supports, advance supports, etc.) and transport equipment (transfer conveyors, self-moving mechanisms for transfer conveyors, crushers, self-moving tail sections of belt conveyors, belt conveyors, etc.) are arranged simultaneously in transport roadways of fully mechanized mining and longwall mining faces. However, these various pieces of equipment operate independently, each with large external dimensions, requiring significant roadway width, and exhibiting complex inter-equipment and movement relationships. This results in cumbersome and inefficient operation, and the support and transport equipment are prone to interference or restriction, hindering the normal advancement of the working face.

[0003] In the prior art, such as the stepping support and transfer integrated device disclosed in Chinese utility model patent CN202420397005.1, the scraper transfer machine, track column, trough column, pushing cylinder, track, lifting device, guiding device and bottom lifting cylinder realize the repeated stepping movement of the scraper transfer machine, track column and trough column.

[0004] However, the solutions in the aforementioned patent documents still have certain problems. Since the track columns and trough columns cannot be adjusted in position during stepping movement, the anchor bolt and cable system on the tunnel roof will be damaged to some extent during the stepping movement.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a simple integrated support and transport device for transport roadways. This device enables the stepping self-moving device and the transfer machine transport trough to move forward alternately, thus avoiding damage to the anchor bolt and cable system when the alternating support mechanism supports the roadway roof.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: It includes a stepping self-moving device, which comprises a track, an alternating support mechanism, and a pushing mechanism. The stepping self-moving device alternately steps forward with the transfer machine's transport trough. The alternating support mechanism includes a first column and a second column. The first column is connected to a first sliding mechanism, which is connected to the track. The first sliding mechanism drives the first column to move back and forth relative to the track. The second column is connected to a second sliding mechanism, which is connected to the transfer machine's transport trough. The second sliding mechanism drives the second column to move back and forth relative to the transfer machine's transport trough.

[0008] This application not only realizes the alternating forward movement of the stepping self-moving device and the transfer machine transport trough, but also, through the first sliding mechanism and the second sliding mechanism, allows the first column and the second support column to adjust their positions according to the position of the anchor bolt and cable system on the roadway roof before extending out to support the roadway roof. This avoids the alternating support mechanism from damaging the anchor bolt and cable system when supporting the roadway roof.

[0009] Based on the above, the first sliding mechanism includes a first housing, a first slider that can move back and forth is provided inside the first housing, the first housing is fixedly installed on the track, the bottom of the first column is fixedly connected to the first slider, a first sliding jack is installed on the first housing, and the first sliding jack drives the first slider to move left and right.

[0010] The first housing and the first slider can effectively limit the possible offset when the first column slides left and right, and prevent the first column from tilting when sliding, thereby ensuring safety when supporting the top plate.

[0011] Based on the above, the second sliding mechanism includes a second housing, a second slider that can move back and forth is provided inside the second housing, the second housing is fixedly installed on the transport trough of the transfer machine, the second column is connected to the second slider, and a second sliding jack is installed on the second housing, the second sliding jack drives the second slider to move left and right.

[0012] The second housing and the second slider can effectively limit the possible offset when the second column slides left and right, and prevent the second column from tilting when sliding, thereby ensuring safety when supporting the top plate.

[0013] Based on the above, the second slider is provided with a guide sleeve, which is slidably fitted onto the second column. A third sliding jack is also provided between the second column and the second box, which drives the second column to slide up and down. The second column is located between the track and the transfer machine transport trough.

[0014] The relative height between the second housing and the second column can be adjusted by the guide sleeve and the third sliding jack, so that when the tunnel floor is uneven, the bottom of the second column can effectively support the tunnel floor.

[0015] Based on the above, a column base is installed at the bottom of the second column.

[0016] The stability of the second column is increased by using the column base.

[0017] Based on the above, the stepping self-moving device further includes a bottom lifting mechanism, which includes a bottom lifting jack and a sliding base. The sliding base slides along the track, and the bottom lifting jack is used to lift the transfer machine transport trough and the crusher from the sliding base.

[0018] By using the lifting jack and the sliding base in combination, the sliding resistance during step-by-step frame movement can be greatly reduced.

[0019] Based on the above, the first column and the second column are both arranged in pairs, and the two tracks are respectively arranged on both sides of the transfer machine transport trough. Support beams are provided between the paired first columns and between the paired second columns.

[0020] The stability of the support structure can be enhanced by using supporting beams and paired first and second columns and tracks.

[0021] Based on the above, connecting rods are provided between the tracks to prevent the tracks from deviating.

[0022] Based on the above, the pushing mechanism includes a first pushing jack, which is connected to the track and the transfer machine transport trough.

[0023] The first push jack enables the stepping self-moving device and the transfer machine transport trough to step forward alternately.

[0024] Based on the above, the pushing mechanism includes a second pushing jack, which is connected to the end hydraulic support and the transfer machine transport trough.

[0025] The second push jack allows the end hydraulic support and the transfer machine conveyor trough to move forward alternately, and can also cooperate with the first push jack. Attached Figure Description

[0039] The technical solution of this utility model will be further described in detail below through specific embodiments. Example 1

[0040] like Figures 1-8 As shown, the simple support and transportation integrated device for the transport roadway in this embodiment includes a stepping self-moving device. The stepping self-moving device includes a track 3, an alternating support mechanism, and a pushing mechanism. The stepping self-moving device can alternately step forward with the transfer machine transport trough 100 through the track 3, the alternating support mechanism, and the pushing mechanism, eliminating the need to use the self-moving mechanism of the transfer machine transport trough 100.

[0041] A crusher is installed on the transfer conveyor trough 100 at the stepping self-moving device.

[0042] Track 3 can be a box-type guide rail, which has high structural strength.

[0043] The alternating support mechanism includes a first column 1 and a second column 2 for alternating support of the top plate during alternating stepping forward movement. These two different columns are respectively connected to the stepping self-moving device and the transfer machine transport trough 100.

[0044] The first column 1 and the second column 2 of the alternating support mechanism provide alternating support when they move forward alternately. When they do not move forward alternately, the first column 1 and the second column 2 can support the roadway roof at the same time.

[0045] The first column 1 is connected to the track 3 of the stepping self-moving device, and the second column 2 is connected to the transfer machine conveyor trough 100. When the first column 1 supports the roadway roof, the track 3 is fixed, the transfer machine conveyor trough 100 is driven forward by the pushing mechanism, and the second column 2 is in a retracted state and moves forward with the transfer machine conveyor trough 100. When the second column 2 supports the roadway roof, the transfer machine conveyor trough 100 is fixed, the track 3 is driven forward by the pushing mechanism, and the first column 1 is in a retracted state and moves forward with the track 3.

[0046] Therefore, this application realizes the alternating stepping forward movement of the stepping self-moving device and the transfer machine transport trough 100. The stepping self-moving device has the advantages of high integration, high automation and high modularity. The overall shape and outline are uniform, the requirements for roadway width are low, the self-moving mechanism of the transfer machine transport trough 100 is eliminated, and the matching and movement relationships between multiple devices are simple, which is conducive to the efficient advancement of the working face.

[0047] The first column 1 is connected to the first sliding mechanism 10, which is connected to the track 3. The first sliding mechanism 10 drives the first column 1 to move back and forth relative to the track 3. The second column 2 is connected to the second sliding mechanism 20, which is connected to the transfer machine transport trough 100. The second sliding mechanism 20 drives the second column 2 to move back and forth relative to the transfer machine transport trough 100.

[0048] Therefore, through the first sliding mechanism 10 and the second sliding mechanism 20, the positions of the first column 1 and the second column 2 can be adjusted according to the position of the anchor bolt and anchor cable system on the roadway roof before the first column 1 and the second column 2 extend out to support the roadway roof. This can avoid the alternating support mechanism from damaging the anchor bolt and anchor cable system when supporting the roadway roof. Example 2

[0049] Based on Embodiment 1, the first sliding mechanism 10 includes a first housing 11, a first slider that can move back and forth is provided inside the first housing 11, the first housing 11 is fixedly installed on the track 3, the bottom of the first column 1 is fixedly connected to the first slider, and a first sliding jack 12 is installed on the first housing 11, the first sliding jack 12 drives the first slider to move left and right.

[0050] The first housing 11 can be fixedly installed on the track 3 by means of pins, bolts and clamps.

[0051] The first housing 11 and the first slider can effectively limit the possible offset when the first column 1 slides left and right, and prevent the first column 1 from tilting when sliding, thereby ensuring the safety of supporting the top plate.

[0052] Furthermore, the first housing 11 is provided with a baffle, and the first column 1 passes through the baffle. The baffle slides left and right with the first column 1, and the baffle can cover the top of the first housing 11.

[0053] Furthermore, the first housing 11 is provided with a jack housing, and the first sliding jack 12 is installed inside the jack housing.

[0054] In other embodiments, a slide rail may be used instead of the first housing 11, so that the first slider is slidably disposed on the slide rail. Example 3

[0055] Based on Embodiment 1, the second sliding mechanism 20 of this embodiment is similar to the first sliding mechanism 10 of Embodiment 2. The second sliding mechanism 20 of this embodiment includes a second housing 21, and a second slider that can move back and forth is provided inside the second housing 21. The second housing 21 is fixedly installed on the transfer machine transport trough 100. For example, the second housing can be installed on the transfer machine transport trough 100 by bolts. The second column 2 is connected to the second slider. A second sliding jack 22 is installed on the second housing 21. The second sliding jack 22 drives the second slider to move left and right.

[0056] Since the transfer machine transport trough 100 has a certain height, the second box 21 is generally set in the upper middle part of the transfer machine transport trough 100. In this way, the second box 21 can be staggered from the guide rail 3 and the first box 11 in the vertical direction, so that the two can be arranged adjacent to each other to avoid interference between related components.

[0057] The second housing 21 and the second slider can effectively limit the possible offset when the second column 2 slides left and right, and prevent the second column 2 from tilting when sliding, thereby ensuring the safety of supporting the top plate. Example 4

[0058] Based on embodiment 3, the second slider is provided with a guide sleeve 23, which is slidably sleeved on the second column 2. A third sliding jack 24 is also provided between the second column 2 and the second box 21. The third sliding jack 24 drives the second column 2 to slide up and down. The second column 2 is located between the track 3 and the transfer machine transport trough 100.

[0059] Since the second column 2 is located inside the track 3 and the first support column 1 is located on the track 3, the first box 11 and the second box 21 can be staggered in the horizontal direction, so they can be arranged adjacent to each other to avoid interference between related components.

[0060] The relative height between the second housing 21 and the second column 2 can be adjusted by the guide sleeve 23 and the third sliding jack 24, so that when the tunnel floor is uneven, the bottom of the second column 2 can also effectively support the tunnel floor. Example 5

[0061] Based on embodiment 4, a column base 25 is installed at the bottom of the second column 2.

[0062] The stability of the second column 2 is increased by using the column base 25. Example 6

[0063] Based on Embodiment 1, the stepping self-moving device also includes a bottom lifting mechanism, which includes a bottom lifting jack 4 and a sliding base 5. The sliding base 5 slides along the track 3, and the bottom lifting jack 4 is used to lift the transfer machine transport trough 100 from the sliding base 5.

[0064] When the first support column 1 and the track 3 are supported, the bottom lifting jack 4 can lift the transfer machine transport trough 100 on the sliding base 5. At this time, the transfer machine transport trough 100 is pushed, and the bottom lifting jack 4 moves synchronously, thereby driving the sliding base 5 to slide on the track 3, which can greatly reduce the sliding resistance.

[0065] Several lifting mechanisms are arranged in front of and behind the crusher in the transfer conveyor trough 100 to smoothly lift the crusher.

[0066] The sliding base 5 can be composed of a connecting box, rollers, bearings and other components. The rollers are installed in the connecting box through bearings and a rotating shaft. The connecting box is installed on the track 3 and the rollers roll on the track 3.

[0067] One end of the lifting jack 4 is connected to the sliding base 5, and the other end is connected to the transfer conveyor trough 100 or the crusher. The lifting jack 4 is kept vertical on the sliding base 5. Since the sliding base 5 has a degree of freedom, both ends of the sliding base 5 can be fixedly connected to the sliding base 5 and the transfer conveyor trough 100 / crusher. In addition, a jack protective shell can be set on the outer periphery of the lifting jack 4 to prevent the lifting jack 4 from shifting.

[0068] Furthermore, a sliding plate is provided on the track 3, and wing plates extend from the sliding plate to the left and right sides of the track 3. The connecting box of the sliding base 5 is embedded in the wing plate, or the bottom of the sliding base 5 is provided with rollers that can slide along the bottom of the wing plate, so that the track 3 can be lifted by the transfer machine transport trough 100 / crusher when the bottom lifting jack is retracted.

[0069] By using the lifting jack 4 and the sliding base 5 in coordination, the sliding resistance during the step-by-step frame movement can be greatly reduced. Example 7

[0070] Based on Embodiment 1, the first column 1 and the second column 2 are both arranged in pairs, and the two tracks 3 are respectively arranged on both sides of the transfer machine transport trough 100. Support beams 6 are provided between the paired first columns 1 and between the paired second columns 2.

[0071] The first sliding mechanism 10 and the second sliding mechanism 20 can also prevent the supporting beam 6 from damaging the anchor bolt and cable system on the roadway roof. The supporting beam 6 can effectively increase the support contact area and enhance the support stability.

[0072] The stability during support can be enhanced by supporting the crossbeam 6 and the paired first column 1, second column 2, and track 3.

[0073] In other embodiments, depending on the shape of the roof, the supporting beam 6 can also adopt an irregular structure, such as an arched box type or a telescopic box type, to achieve full connection and support with the roof of the roadway. Example 8

[0074] Based on Embodiment 1, a connecting rod 7 is provided between the tracks 3. The connecting rod 7 can be set at the front of the track 3. The front of the track 3 is located below the bridge section of the transfer machine, which can effectively arrange the connecting rod 7 to prevent the track 3 from deviating. Example 9

[0075] Based on Embodiment 1, the pushing mechanism includes a first pushing jack 8, which is connected to the track 3 and the transfer machine transport trough 100, so that the stepping self-moving device and the transfer machine transport trough 100 can alternately step forward. The first pushing jack 8 can be set in the middle of the track 3. Example 10

[0076] Based on embodiment 1 or 9, the pushing mechanism includes a second pushing jack 9, which is connected to the end hydraulic support 200 and the transfer machine transport trough 100, so that the end hydraulic support 200 and the transfer machine transport trough 100 can move forward alternately. The second pushing jack 9 is located behind the track 3 and can cooperate with the first pushing jack 8.

[0077] 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.
