Description

Technical Field

[0001] This utility model relates to the field of downhole mining technology with steep slopes, and in particular to an end support. Background Technology

[0002] In underground mining operations, the roof support can support the roof, thereby ensuring the stability of the entire roadway, preventing debris from falling from the roof and damaging equipment or causing personnel injuries, and improving the overall safety of underground mining operations.

[0003] However, for deep-slope underground mining operations, the triangular point of the working face transport roadway is the turning point between the slope and the plane. The top wall is usually inclined and sloped, which makes conventional flat-top supports unsuitable, resulting in greater difficulty in supporting this area at present.

[0004] Therefore, there is a need to provide an end bracket to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this application is to provide an end support to solve, to some extent, the problem that it is impossible to quickly and stably support the triangular point of the transport roadway in downhole mining operations with steep slopes.

[0006] The end bracket provided by this utility model includes a base, a lifting mechanism, and a support mechanism. The lifting mechanism includes a first lifting component and a second lifting component arranged vertically on the base, and the height of the first lifting component is greater than the height of the second lifting component. The support mechanism includes a support beam, a rotary beam, and a first driving member. The support beam is connected to the ends of the first and second lifting components away from the base, so that the support beam is arranged at an angle. One end of the rotary beam is rotatably connected to one end of the support beam, and one end of the first driving member is rotatably connected to the support beam, and the other end is rotatably connected to the rotary beam.

[0007] The base is rectangular, the first lifting component includes a first telescopic column, the second lifting component includes a second telescopic column, the first telescopic column and the second telescopic column are corresponding to each other on the base, and the height of the first telescopic column at the front end is greater than the height of the second telescopic column at the rear end.

[0008] Specifically, there are at least two first telescopic columns arranged in parallel, and the second telescopic columns are arranged in a one-to-one correspondence with the first telescopic columns; the width of the support beam can cover the first and second telescopic columns.

[0009] Specifically, the second lifting assembly further includes a telescopic box and a guide box. Both the telescopic box and the guide box are sleeved on the outside of the second telescopic column, and the guide box is sleeved on the outside of the telescopic box, so that the telescopic box can extend and retract relative to the guide box.

[0010] The support beam has a first connecting ear at the position corresponding to the first driving member, and the rotary beam has a second connecting ear at the position corresponding to the first driving member. One end of the first driving member is rotatably connected to the first connecting ear, and the other end is rotatably connected to the second connecting ear.

[0011] Specifically, the slewing beam includes a base square box, an extended square box, and a second driving component; one end of the base square box is rotatably connected to the support beam, the base square box is fitted outside the extended square box, one end of the extended square box protrudes from the base square box, and one end of the second driving component is connected to the base square box, while the other end is rotatably connected to the end of the extended square box that protrudes from the base square box.

[0012] The end bracket provided by this utility model also includes a pushing component, which is disposed between two adjacent bases and includes a third driving component. One end of the third driving component is connected to one of the bases and the other end is connected to the other base. The third driving component can drive the two adjacent bases to move in a direction that approaches or moves away from each other.

[0013] Specifically, a third connecting ear is formed on the base corresponding to the position of the third driving member. The two ends of the third driving member are rotatably connected to the third connecting ears on two adjacent bases, and there are multiple third driving members. The third connecting ears are correspondingly arranged with the third driving members.

[0014] Furthermore, the end bracket provided by this utility model also includes an anti-slip component, which includes a first anti-slip member and a second anti-slip member. The first anti-slip member is rotatably connected to the end face of the rear end of the base, and the second anti-slip member is rotatably connected to the end of the support beam away from the rotating beam.

[0015] Furthermore, the end bracket provided by this utility model also includes an anti-slip telescopic component, one end of which is rotatably connected to the first lifting assembly.

[0016] Compared with the prior art, the end bracket provided by this utility model has the following advantages:

[0017] The end bracket provided by this utility model includes a base, a lifting mechanism, and a support mechanism. The lifting mechanism includes a first lifting component and a second lifting component arranged vertically on the base, and the height of the first lifting component is greater than the height of the second lifting component. The support mechanism includes a support beam, a rotary beam, and a first driving component. The support beam is connected to the ends of the first and second lifting components away from the base, so that the support beam is arranged at an inclination. One end of the rotary beam is rotatably connected to one end of the support beam, and one end of the first driving component is rotatably connected to the support beam, and the other end is rotatably connected to the rotary beam.

[0018] Analysis shows that the first and second lifting components, which are vertically mounted on the base, can provide an installation and support foundation for the support mechanism. Since the height of the first lifting component in this application is greater than the height of the second lifting component, the support mechanism can form an inclined support surface after being connected to the first and second lifting components, thus enabling it to better adapt to the stable support of the top wall of the triangular point position of the transport roadway in steep underground mining operations.

[0019] Furthermore, since the first and second lifting components in this application can extend and retract in the vertical direction, the tilt angle of the support mechanism can be made consistent with the tilt angle of the top wall at the triangular point position, thereby ensuring the fit with the top wall.

[0020] The support mechanism provided in this application includes a support beam, a slewing beam, and a first drive component. The support beam is connected to the aforementioned first lifting component and second lifting component. One end of the slewing beam is rotatably connected to one end of the support beam. Therefore, the slewing beam can serve as a further extension of the support beam, achieving both contact and support with the top wall. On the other hand, the end of the slewing beam away from the support beam can be used to further support the slope transport equipment and the flat-top support, preventing the equipment on the slope from sliding down.

[0021] Accordingly, since one end of the first driving member in this application is rotatably connected to the support beam and the other end is rotatably connected to the slewing beam, when the first driving member extends or retracts, the slewing beam can rotate relative to the support beam, thereby achieving the purpose of aligning and contacting with the equipment on the slope and fitting against the top wall, ensuring the safety and stability of the overall mining system operation.

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0026] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0027] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figure 1 As shown, the end bracket provided by this utility model includes a base 1, a lifting mechanism, and a support mechanism. The lifting mechanism includes a first lifting component 2 and a second lifting component 3 arranged vertically on the base 1, and the height of the first lifting component 2 is greater than the height of the second lifting component 3. The support mechanism includes a support beam 4, a rotary beam 5, and a first driving component 6. The support beam 4 is connected to the ends of the first lifting component 2 and the second lifting component 3 away from the base 1, so that the support beam 4 is arranged at an inclination. One end of the rotary beam 5 is rotatably connected to one end of the support beam 4, and one end of the first driving component 6 is rotatably connected to the support beam 4, and the other end is rotatably connected to the rotary beam 5.

[0031] Compared with the prior art, the end bracket provided by this utility model has the following advantages:

[0032] The end bracket provided by this utility model can provide an installation and support foundation for the support mechanism through the first lifting component 2 and the second lifting component 3 arranged vertically on the base 1. Since the height of the first lifting component 2 in this application is greater than the height of the second lifting component 3, the support mechanism can form an inclined support surface after being connected with the first lifting component 2 and the second lifting component 3, thereby being able to better adapt to the stable support of the top wall of the triangular point position of the transport roadway in the operation of mining on a large slope.

[0033] Furthermore, since the first lifting component 2 and the second lifting component 3 in this application can extend and retract in the same vertical direction, the tilt angle of the support mechanism can be made consistent with the tilt angle of the top wall at the triangular point position, thereby ensuring the fit with the top wall.

[0034] The support mechanism provided in this application includes a support beam 4, a slewing beam 5, and a first driving component 6. The support beam 4 is connected to the first lifting component 2 and the second lifting component 3 mentioned above. One end of the slewing beam 5 is rotatably connected to one end of the support beam 4. Therefore, the slewing beam 5 can serve as a further extension of the support beam 4. On the one hand, it can achieve fitting and support with the top wall. On the other hand, the end of the slewing beam 5 away from the support beam 4 can be used to further support the slope transport equipment and the flat-top support, thus preventing the slope equipment from sliding down.

[0035] Accordingly, since one end of the first driving member 6 in this application is rotatably connected to the support beam 4 and the other end is rotatably connected to the slewing beam 5, when the first driving member 6 extends or retracts, the slewing beam 5 can rotate relative to the support beam 4, thereby achieving the purpose of aligning and contacting with the equipment on the slope and fitting against the top wall, ensuring the safety and stability of the overall mining system operation.

[0036] It should be noted that in this application, the connection between the first lifting component 2 and the second lifting component 3 and the support beam 4 can be a fixed connection, but the first lifting component 2 and the second lifting component 3 need to extend and retract synchronously to avoid the problem of breakage at the connection position between the support beam 4 and the first lifting component 2 and the second lifting component 3.

[0037] To improve the adaptability of the end support, the first lifting component 2 and the second lifting component 3 in this application can be rotatably connected to the support beam 4. Therefore, the support tilt angle of the support beam 4 can be changed by the extension and retraction of the first lifting component 2 and the second lifting component 3 at different amplitudes, so as to better adapt to the tilt angle of the top wall in different slope environments, improve the fit, and ensure the support stability.

[0038] Optionally, such as Figure 1 As shown, the base 1 in this application is rectangular, the first lifting component 2 includes a first telescopic column, the second lifting component 3 includes a second telescopic column, the first telescopic column and the second telescopic column are corresponding to each other on the base 1, and the height of the first telescopic column at the front end is greater than the height of the second telescopic column at the rear end.

[0039] In this application, the front end of the base 1 refers to the end closer to the equipment on the slope, while the rear end is the end closer to the wall. It can be understood that since the support beam 4 is a straight structure, the first telescopic column and the second telescopic column need to be aligned front to back to ensure that the support beam 4 can extend along the direction of the slope.

[0040] In this application, both the first and second telescopic columns are telescopic hydraulic cylinders, which are used to support and control the support beam 4 by extending and retracting the hydraulic cylinders.

[0041] Preferably, such as Figure 1 As shown, there are at least two first telescopic columns in this application, which are arranged in parallel, and the second telescopic columns are arranged in a one-to-one correspondence with the first telescopic columns; the width of the support beam 4 can cover the first telescopic columns and the second telescopic columns.

[0042] Since the base 1 in this application is rectangular, the two first telescopic columns and the two second telescopic columns are respectively set at the four corners of the rectangular base 1. Correspondingly, the support beam 4 in this application can correspond to a set of front and rear corresponding first telescopic columns and second telescopic columns. However, this application preferably uses a support beam 4 with a wider width. That is, the connection area of ​​the support beam 4 provided in this application can meet the simultaneous connection of the two first telescopic columns and the two second telescopic columns. Since the support beam 4 is wider, it also has a wider support surface, thereby ensuring the support of the top wall.

[0043] More preferably, such as Figure 1As shown, the second lifting assembly 3 in this application also includes a telescopic box 301 and a guide box 302. Both the telescopic box 301 and the guide box 302 are sleeved on the outside of the second telescopic column, and the guide box 302 is sleeved on the outside of the telescopic box 301, so that the telescopic box 301 can extend and retract relative to the guide box 302.

[0044] Since the first telescopic column in this application needs to be connected to the anti-slip telescopic components described below, the guide box 302 and telescopic box 301 provided outside the second telescopic column can provide protection for the second telescopic column, thereby ensuring the service life of the overall support to a certain extent.

[0045] It is understandable that, such as Figure 1 As shown, in this application, the support beam 4 has a first connecting ear 401 formed at the position corresponding to the first driving member 6, and the rotary beam 5 has a second connecting ear 5011 formed at the position corresponding to the first driving member 6. One end of the first driving member 6 is rotatably connected to the first connecting ear 401, and the other end is rotatably connected to the second connecting ear 5011.

[0046] The first driving component 6 in this application is a telescopic hydraulic cylinder. By forming a first connecting lug 401 on the outside of the support beam 4 and a second connecting lug 5011 on the outside of the rotary beam 5, a foundation can be provided for the installation of the first driving component 6, thereby enabling the driving and holding of the rotary beam 5 through the first driving component 6.

[0047] Optionally, such as Figure 1 As shown, the slewing beam 5 in this application includes a base square box 501, an extended square box 502, and a second driving member 503; one end of the base square box 501 is rotatably connected to the support beam 4, the base square box 501 is sleeved on the outside of the extended square box 502, one end of the extended square box 502 protrudes out of the base square box 501, and one end of the second driving member 503 is connected to the base square box 501, and the other end is rotatably connected to the end of the extended square box 502 that protrudes out of the base square box 501.

[0048] By further configuring the extended rectangular box 502 and the corresponding connected second driving component 503, the extended rectangular box 502 can extend and retract relative to the basic rectangular box 501, thereby making the length of the overall slewing beam 5 adjustable. On the one hand, it can ensure stable support for the top wall at the triangular point position, and on the other hand, it can adjust the length according to the actual situation, so as to smoothly contact the flat-top support on the slope, realize the support for the flat-top support, and avoid the flat-top support from sliding down the slope, which would affect the stability of the support.

[0049] Optionally, such as Figure 1As shown, the end bracket provided by this utility model also includes a pushing component 7, which is disposed between two adjacent bases 1. The pushing component 7 includes a third driving component, one end of which is connected to one of the bases 1 and the other end of which is connected to the other base 1. The third driving component can drive the two adjacent bases 1 to move in a direction that approaches or moves away from each other.

[0050] The third driving component in this application is also a telescopic hydraulic cylinder. By connecting the pushing component 7 between two adjacent bases 1, when the support position needs to be adjusted, one of the two adjacent end supports can be determined as the positioning base. The first lifting component 2 and the second lifting component 3 are extended to make the support beam 4 fit tightly against the top wall, ensuring the position is fixed. Then, by extending or retracting the pushing component 7, the other end support is pushed or pulled closer in a direction away from or towards, thereby completing the position adjustment.

[0051] Once the position adjustment is complete, the support beam 4 can be brought into close contact with the top wall by extending the first lifting component 2 and the second lifting component 3, thus completing the position adjustment.

[0052] It should be noted that, following the steps described above, multiple end supports can also be moved autonomously.

[0053] Accordingly, in this application, a third connecting ear 701 is formed on the base 1 at the position corresponding to the third driving member. The two ends of the third driving member are rotatably connected to the third connecting ear 701 on two adjacent bases 1, and there are multiple third driving members, with the third connecting ear 701 corresponding to the third driving member.

[0054] Optionally, such as Figure 1 As shown, the end bracket provided by this utility model also includes an anti-slip component, which includes a first anti-slip member 8 and a second anti-slip member 9. The first anti-slip member 8 is rotatably connected to the end face of the rear end of the base 1, and the second anti-slip member 9 is rotatably connected to the end of the support beam 4 away from the rotating beam 5.

[0055] In this application, the first anti-slip member 8 is located on the end face of the rear end of the base 1, and the second anti-slip member 9 is located on the end face of the support beam 4 away from the rotating beam 5. The first anti-slip member 8 and the second anti-slip member 9 can abut against the side wall at the triangular point position, thereby preventing the end support from slipping towards the side wall and ensuring the stability of the support for the top wall and the stability of the support for the equipment on the slope.

[0056] Preferably, the end bracket provided by this utility model further includes an anti-slip telescopic component, one end of which is rotatably connected to the first lifting assembly 2.

[0057] The anti-slip telescopic component in this application is also a telescopic cylinder, and one end of the telescopic cylinder is rotatably connected to the non-telescopic position of the first lifting component 2, while the other end is rotatably connected to the bottom of the flat-top support on the slope.

[0058] It is understandable that, since the extended rectangular box 502 described above can support the top of the flat-top bracket, the anti-slip telescopic component that can be rotatably connected to the bottom of the flat-top bracket can further improve the support for the equipment on the slope, thereby ensuring the stability of the equipment on the slope and preventing the equipment from sliding down the slope.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
