Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The machine roadway advance support assembly provided in this embodiment of the utility model is applied to roadways, such as... Figure 1 and Figure 2 As shown, the system includes at least two machine lane advance supports 1 connected end to end. Each machine lane advance support 1 includes a base 11, a telescopic member 12, a control member 13, and a support member 14. The control member 13 is disposed on the base 11. One end of the telescopic member 12 is connected to the base 11, and the other end is connected to the support member 14. The control member 13 is electrically connected to the adjacent machine lane advance support 1. In use, the user controls the extension and retraction of the telescopic member 12 on the adjacent machine lane advance support through the control member 13, so that the base 11 contacts the bottom plate of the lane, and the support member 14 contacts the top plate of the lane.

[0023] After adopting the above solution, the user can control the adjacent machine lane advance support 1 through the control component 13 at the machine lane advance support where he / she is located, and then control the extension and retraction of the telescopic component 12, so that the base 11 contacts the bottom plate of the lane and the support component 14 contacts the top plate of the lane, thereby protecting the top plate of the lane from sinking. By controlling the adjacent machine lane advance support 1 through the control component 13 at the machine lane advance support where he / she is located, it is convenient for the user to operate on the adjacent frame, avoiding the risk of limited operating space on the local frame. At the same time, operating on the adjacent frame also makes it easier to observe the situation ahead, making the machine lane advance support assembly more convenient during movement.

[0024] Furthermore, by setting at least two machine roadway advance supports 1 connected end to end, the front end of the machine roadway advance support 1 can act on the working face whether it is moving forward or backward.

[0025] In the specific implementation process of this embodiment, such as Figure 2 and Figure 3As shown, the telescopic member 12 includes a first telescopic column 121 and a second telescopic column 122. One end of the first telescopic column 121 and the second telescopic column 122 are both connected to the base 11, and the other end of the first telescopic column 121 and the second telescopic column 122 are both connected to the support member 14.

[0026] More specifically, one end of the first telescopic column 121 and the second telescopic column 122 are both connected to the base 11, so that the base 11 protects the bottom plate of the roadway. The other end of the first telescopic column 121 and the second telescopic column 122 are both connected to the support member 14, so that the support member 14 protects the top plate of the roadway and prevents coal slag or gravel from falling from the top of the roadway.

[0027] In the specific implementation process of this embodiment, such as Figure 2 and Figure 3 As shown, the telescopic member 12 also includes a telescopic connecting rod 123, one end of which is connected to the base 11 and the other end is connected to the support member 14.

[0028] More specifically, the telescopic linkage 123 provides better support for the machine roadway advance support 1 when supporting the roadway.

[0029] Furthermore, the first telescopic column 121, the second telescopic column 122, and the telescopic connecting rod 123 can be hydraulically driven, electrically driven, or other devices that realize telescopic movements.

[0030] In the specific implementation process of this embodiment, such as Figure 2 and Figure 3 As shown, the support member 14 is provided with a valve assembly 141 on the side near the base 11.

[0031] In the specific implementation process of this embodiment, such as Figure 2 and Figure 3 As shown, each of the machine lane advance supports also includes a pipe 15, one end of which is connected to the valve group 141, and the other end of which is connected to the telescopic member 12 and the connecting member 2 respectively.

[0032] More specifically, high-pressure liquid is provided in the pipeline 15, and the flow of high-pressure liquid in the pipeline 15 into the expansion joint 12 and the connecting member 2 is controlled by the switch valve group 141.

[0033] Furthermore, connector 2 is a push cylinder, which realizes the connection between two machine lane advance supports that are connected end to end.

[0034] In the specific implementation process of this embodiment, such as Figure 2 and Figure 3As shown, both the telescopic member 12 and the connecting member 2 are provided with channels, and the pipeline 15 is located in the channels.

[0035] More specifically, since the pipeline 15 contains high-pressure liquid, it cannot be bent. Therefore, channels are provided on the expansion joint 12 and the connector 2 for the pipeline 15 to pass through, to prevent the pipeline 15 from being damaged by friction with other components and thus causing it to burst, so as to prevent the personnel working in the tunnel from being threatened.

[0036] Furthermore, channels are provided on the inner sides of the first telescopic column 121, the second telescopic column 122, and the telescopic connecting rod 123 to avoid friction of the pipe 15, increase its service life, and reduce purchase costs.

[0037] In the specific implementation process of this embodiment, such as Figure 2 and Figure 3 As shown, the support member 14 includes a top beam 142, with a valve assembly 141 provided at one end of the top beam 142 near the base 11, and the other end of the top beam 142 away from the base 11 in contact with the roof of the tunnel.

[0038] More specifically, the valve assembly 141 of the control pipeline 15 is mounted on the top beam 142, which further avoids friction of the pipeline 15; when the top beam 142 is supported by the support member 14, it contacts the roof of the roadway, thereby protecting the roof of the roadway.

[0039] In the specific implementation process of this embodiment, such as Figure 2 As shown, the support member 14 also includes a protective member 143, which is movably connected to the top beam 142.

[0040] More specifically, the protective component 143 is movably connected to the top beam 142. The protective component 143 unfolds when in operation and folds and stores under the top beam 142 when not in operation.

[0041] In the specific implementation process of this embodiment, such as Figure 2 As shown, the protective component 143 includes a driving part 1431 and a protective part 1432, with the driving part 1431 connected to the protective part 1432.

[0042] More specifically, the protective component 143 includes a driving part 1431 and a protective part 1432. The driving part 1431 drives the protective part 1432, enabling the protective part 1432 to be folded and unfolded.

[0043] Furthermore, the drive unit 1431 can be electrically driven or hydraulically driven. If it is hydraulically driven, the valve group 141 is connected to the drive unit 1431 through the pipeline 15, thereby driving the folding and unfolding of the protection unit 1432.

[0044] The workflow provided by this utility model embodiment is as follows: The user controls the adjacent machine lane advance support 1 via control component 13 from the advance support in their current machine lane, thereby controlling the extension and retraction of the first telescopic column 121, the second telescopic column 122, and the telescopic connecting rod 123. This causes the top beam 142 to contact the roof of the roadway when supported, thus protecting the roof of the roadway and preventing it from sinking. This also allows the base 11 to contact the bottom of the roadway. The user then controls the adjacent machine lane advance support 1 via control component 13 from the advance support in their current machine lane. This design facilitates operation from adjacent frames, avoiding the risks associated with limited operating space on the main frame. Operation from adjacent frames also allows for better observation of the surrounding area, making the movement of the machine roadway advance support assembly more convenient. By providing channels on the telescopic component 12 and connecting component 2 for the pipe 15 to pass through, friction between the pipe 15 and other components prevents damage and potential pipe bursts, thus protecting personnel working in the roadway. When the protection unit 1432 is deployed, it protects the open roof area in front from falling coal or gravel, ensuring the safety of personnel.

[0045] In summary, when using this utility model, the user controls the adjacent machine lane advance support 1 via the control component 13 from the advance support in their current machine lane, thereby controlling the extension and retraction of the telescopic component 12. This allows the base 11 to contact the bottom plate of the roadway, and the support component 14 to contact the top plate of the roadway, thus protecting the top plate of the roadway from sinking. By controlling the adjacent machine lane advance support 1 via the control component 13 from the current machine lane advance support, the user can easily operate on the adjacent support, avoiding the risks associated with limited operating space on the current support. At the same time, operating on the adjacent support also facilitates observation of the situation ahead, making the machine lane advance support assembly more convenient to move.

[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
