DETAILED DESCRIPTION

[0028] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0029] In the present disclosure, "inner" and "outer" refer to the contour of the respective components as such, unless otherwise stated. In addition, the terms "first", "second", and the like used in the present disclosure are intended to distinguish one element from another element, and do not have sequential or important meanings. In the following description, the same numbers refer to the same or similar elements unless otherwise indicated.

[0030] In the related art, the construction of a temporary sealing wall in a coal mine is an essential technology in the production of a high-efficiency coal mine with double-lane mining, and plays an important role in controlling the ventilation of the roadway, blocking harmful gases such as gas and carbon monoxide in the goaf. Among them, the construction of the sealing wall can be to build a skeleton of the sealing wall by a plurality of supporting rods, and to finally form a temporary sealing wall in a coal mine by arranging a sealing cloth on the skeleton of the sealing wall. However, in the actual construction process, in order to improve the overall stability of the sealing wall, the two ends of the supporting rod can be buried in the roadway wall to make the sealing wall more firm, but this form of fixing the supporting rod will cause damage to the roadway wall, and there is a certain safety hazard.

[0031] Based on this, the first aspect of the present disclosure provides a supporting rod, referring to Figure 1 The supporting rod includes a rod body 1 and a supporting mechanism 2, the rod body 1 includes a first supporting assembly 201 and a second supporting assembly 202, the first supporting assembly 201 is connected to the first end of the rod body 1 through a first elastic member 3, and the second supporting assembly 202 is installed at the second end of the rod body 1 away from the first elastic member 3. The first elastic member 3 is used to make the first supporting assembly 201 and the second supporting assembly 202 abut the inner wall surface of the roadway 10 respectively, so that the rod body 1 is supported in the roadway 10.

[0032] In the present disclosure, the two ends of the supporting rod are not buried in the roadway 10, and artificial damage to the roadway 10 by the supporting rod is avoided as much as possible. Specifically, the first supporting assembly 201 and the second supporting assembly 202 arranged at the two ends of the rod body 1 abut the inner wall surface of the roadway 10 respectively, and the supporting rod can be supported in the roadway 10 by the elastic force of the first elastic member 3.

[0033] In some embodiments, referring to Figure 2 and Figure 3 The rod body 1 is configured as a hollow pipe body, the first supporting assembly 201 includes a first supporting plate 2011 and a guide column 2012, one end of the guide column 2012 is fixedly connected to the first supporting plate 2011, the other end is movably inserted into the rod body 1, the first elastic member 3 is abutted between the rod body 1 and the first supporting plate 2011, and the first supporting plate 2011 is used to directly or indirectly abut the inner wall surface of the roadway 10.

[0034] In the present disclosure, the first support assembly 201 comprises a first support plate 2011 and a guide column 2012, and the rod body 1 is configured as a hollow pipe body, one end of the guide column 2012 is fixedly connected to the first support plate 2011, and the other end is movably inserted into the rod body 1, and the first elastic member 3 is abutted between the rod body 1 and the first support plate 2011. When a support rod is installed, the length of the guide column 2012 inserted into the rod body 1 can be adjusted, that is, the compression amount of the first elastic member 3 is changed, so that the first support assembly 201 and the second support assembly 202 at both ends of the rod body 1 are respectively abutted to the inner wall surface of the roadway 10.

[0035] In the present disclosure, the overall length of the support rod which is not installed in the roadway 10 is greater than the width or height of the roadway 10, that is, when the support rod is installed, the guide column 2012 needs to be moved towards the one end of the second support assembly 202, so that the first elastic member 3 is compressed, at this time, the overall length of the support rod is smaller than the width or height of the roadway 10, and then the support rod is placed horizontally or vertically in the roadway 10, and then the guide column 2012 can be moved towards the one end away from the second support assembly 202 under the elastic force of the first elastic member 3, and when the guide column 2012 stops moving, that is, the installation of the support rod is completed, at this time, the first elastic member 3 is still in the compressed state.

[0036] In the present disclosure, referring to Figure 1 and Figure 4 When the support rod is fixed in the roadway 10, the first support plate 2011 can directly abut the inner wall surface of the roadway 10, the first support plate 2011 can be configured as a circular pad plate, the diameter of the first support plate 2011 is greater than the diameter of the guide column 2012 and the rod body 1, so that the first support plate 2011 can contact a larger area of the inner wall surface of the roadway 10, thereby providing good stability for the rod body 1.

[0037] In some embodiments, referring to Figure 1 and Figure 4 In the present disclosure, considering that the pipe wall of the rod body 1 is thin, in order to make the contact between the first elastic member 3 and the rod body 1 more stable, a first stopper 4 can be arranged at the end of the rod body 1 facing the first elastic member 3, and the first stopper 4 contacts the first elastic member 3.

[0038] In the present disclosure, the first stopper 4 can be a flange plate welded on the rod body 1.

[0039] In some embodiments, referring to Figure 1 and Figure 4As shown, the first elastic member 3 can be sleeved on the guide column 2012, and in order to make the support rod be more firmly arranged in the roadway 10, the first support assembly 201 further comprises a second elastic member 5 sleeved outside the first elastic member 3, and one end of the second elastic member 5 is fixedly connected to the first support plate 2011, and the other end of the second elastic member 5 is used for abutting against the first stopper 4, under the joint action of the first elastic member 3 and the second elastic member 5, the support rod can be more firmly arranged in the roadway 10.

[0040] In some embodiments, with reference to Figure 1 and Figure 4 As shown in the present disclosure, the first elastic member 3 and the second elastic member 5 are both configured as springs, and the elastic force of the second elastic member 5 is greater than that of the first elastic member 3.

[0041] In some embodiments, with reference to Figure 1 and Figure 4 As shown in the present disclosure, a first flexible gasket 6 can be arranged on the end face of the first support plate 2011 away from the guide column 2012, the first flexible gasket 6 can be made of rubber material, which can increase the friction between the first support plate 2011 and the inner wall surface of the roadway 10, so that the support rod is not easy to shake after installation, and at the same time, if the roadway wall is a mine wall of coal and rock body with low strength, the first support assembly 201 and the second support assembly 202 at both ends of the rod body 1 still have the risk of damaging the roadway wall when extruding the roadway wall in the direction away from the rod body 1, therefore, the first flexible gasket 6 also plays a role in protecting the roadway wall.

[0042] In some embodiments, with reference to Figures 1 to 3 As shown, the second support assembly 202 comprises a second support plate 2021, a screw rod 2022 and a nut 2023 threadedly connected to the screw rod 2022, one end of the screw rod 2022 is fixedly connected to the first support plate 2011, and the other end is movably inserted into the rod body 1, the second end of the rod body 1 is provided with a second stopper 7 for abutting against the nut 2023, and the second support plate 2021 is used for directly or indirectly abutting against the inner wall surface of the roadway 10.

[0043] In the present disclosure, the second stopper 7 can be a flange plate welded on the rod body 1.

[0044] Specifically, in the first embodiment, when installing a support rod, the support rod can be assembled as follows: first, the nut 2023 is rotated to fit the second support plate 2021, then the screw rod 2022 is inserted into one end of the rod body 1, at this time the nut 2023 contacts the second stopper 7, the guide column 2012 is inserted into the other end of the rod body 1, at this time the first elastic member 3 only contacts the first stopper 4 but is not compressed, and the overall length of the support rod is less than the width or height of the tunnel 10. After the support rod is assembled, the personnel move the assembled support rod to the position where the sealed wall is to be built, hold the rod body 1 horizontally or vertically, then rotate the nut 2023 (when the nut 2023 is rotated, it is necessary to ensure that the screw rod 2022 does not rotate around its own axis), as the nut 2023 rotates, the distance between the nut 2023 and the second support plate 2021 gradually increases, the rod body 1 gradually moves towards one end of the first elastic member 3, and the first elastic member 3 and the second elastic member 5 start to contract, and the support force of the support rod fixed in the tunnel 10 is provided by the elastic force of the first elastic member 3 and the second elastic member 5. In addition, by adjusting the position of the nut 2023, the compression amount of the first elastic member 3 and the second elastic member 5 can be indirectly adjusted, that is, the elastic force of the first elastic member 3 and the second elastic member 5 can be adjusted.

[0045] In the second embodiment, when installing a support rod, the support rod can be assembled as follows: first, the nut 2023 is rotated to fit the second support plate 2021, then the screw rod 2022 is inserted into one end of the rod body 1, at this time the nut 2023 contacts the second stopper 7, the guide column 2012 is inserted into the other end of the rod body 1, at this time the first elastic member 3 only contacts the first stopper 4 but is not compressed, and the overall length of the support rod is less than the width or height of the tunnel 10. After the support rod is assembled, the personnel move the assembled support rod to the position where the sealed wall is to be built, hold the rod body 1 horizontally or vertically;

[0046] After the placement, because the elastic force of the first elastic member 3 is smaller than that of the second elastic member 5, and in order to reduce the time required for fixing the support rod in the tunnel 10 as much as possible, the first stopper 4 can be pressed to compress the first elastic member 3 (because the elastic force of the first elastic member 3 is small, the person does not need to use a large force, and the first elastic member 3 can be easily pressed by the first stopper 4) by manually moving the rod body 1 (at this time, the person can move the rod body 1 by holding the rod body 1), until the first stopper 4 is close to the end of the second elastic member 5 away from the first support plate 2011 (at this time, the second elastic member 5 is not pressed by the first stopper 4), and then the person needs to continuously apply a force to the rod body 1 to press the first elastic member 3, and in the process of continuously applying the force to the rod body 1 to press the first elastic member 3, the nut 2023 is rotated, and then when the nut 2023 contacts the second stopper 7, the person can remove the force applied to the rod body 1 to press the first elastic member 3, at this time, the elastic force provided by the first elastic member 3 can preliminarily fix the support rod in the tunnel 10;

[0047] Finally, in order to ensure that the support rod can be more firmly fixed in the tunnel 10, the nut 2023 needs to be continuously rotated, and with the rotation of the nut 2023, the first stopper 4 starts to press the second elastic member 5 and makes the second elastic member 5 shrink, which can be determined by the experience of the person, and when the second elastic member 5 is compressed to a certain extent, the rotation of the nut 2023 is stopped. The fixation of one support rod is completed.

[0048] In the second embodiment described above, the first elastic member 3 serves to provide an initial support force for the preliminary installation of the support rod, and when the support rod is preliminarily fixed in the tunnel 10 by the first elastic member 3, the second elastic member 5 can be compressed by continuously rotating the nut 2023 to provide strong support for the support rod.

[0049] In the present disclosure, reference is made to Figure 1 and Figure 3 When the support rod is fixed in the tunnel 10, the second support plate 2021 can directly abut the inner wall surface of the tunnel 10, and the second support plate 2021 can be configured as a circular pad plate, the diameter of the second support plate 2021 is greater than the diameter of the screw rod 2022 and the rod body 1, which can make the area of the inner wall surface of the tunnel 10 contacted by the second support plate 2021 larger, and provide good stability for the rod body 1.

[0050] In some embodiments, reference is made to Figure 1 and Figure 3As shown, in the present disclosure, a second flexible gasket 8 can be arranged on the end face of the second support plate 2021 away from the screw rod 2022, the second flexible gasket 8 can be made of rubber material, which can increase the friction between the second support plate 2021 and the inner wall of the roadway 10, so that the support rod is not easy to shake after installation. If the wall of the roadway 10 is a mine wall with low strength coal rock body, the first support assembly 201 and the second support assembly 202 at both ends of the rod body 1 still have the risk of damaging the wall of the roadway 10 when they are pressed towards the direction away from the rod body 1. Therefore, the second flexible gasket 8 plays a role in protecting the wall of the roadway 10.

[0051] On the basis of the above technical solution, the second aspect of the present disclosure further provides a sealing wall, which comprises a framework 9 and a sealing cloth, the framework 9 comprises a plurality of longitudinal support rods extending in the vertical direction and arranged at intervals in the horizontal direction, and a plurality of transverse support rods extending in the horizontal direction and arranged at intervals in the vertical direction, the longitudinal support rods and / or the transverse support rods adopt the support rod of the above-mentioned first aspect or any of the embodiments of the above-mentioned first aspect; the sealing cloth is laid on the framework 9.

[0052] In the present disclosure, with reference to Figure 5 As shown, after the first embodiment or the second embodiment is used to fix a plurality of support rods, the framework 9 of the sealing wall is formed, the sealing cloth can be laid on the framework 9, and after the laying is completed, the sealing wall can be finally sealed by spraying mortar on the surface, so that there is no gap between the sealing cloth and the wall of the roadway 10.

[0053] In some embodiments, the intersection of the longitudinal support rods and the transverse support rods is connected by a fixing member, which can be an existing device, such as a ring hoop, a cross fixing clamp, etc., or the intersection of the longitudinal support rods and the transverse support rods is connected and fixed by tightening with a wire.

[0054] The process of constructing the sealing wall by the support frame: in the present disclosure, the support rod adopts a split design and mainly comprises three parts, namely the rod body 1, the first support assembly 201 and the second support assembly 202. When it is necessary to build a sealing wall in the roadway 10, considering that the space in the roadway 10 is relatively narrow, a plurality of rod bodies 1, a plurality of first support assemblies 201 and a plurality of second support assemblies 202 can be transported into the roadway 10 in batches, then a plurality of support rods can be installed and fixed according to the first embodiment or the second embodiment to form the framework 9, then the sealing cloth is laid on the framework 9, and after the laying is completed, the gap between the sealing cloth and the wall of the roadway 10 is completely sealed by spraying mortar.
