Description

Technical Field

[0001] This utility model relates to the field of deep-slope underground mining technology, and in particular to a hydraulic support system. Background Technology

[0002] In deep-slope mining operations, hydraulic supports are needed to support the roof. However, due to the steep slope, the center of gravity of the hydraulic supports shifts upward, posing a risk of tipping downhill.

[0003] Furthermore, the roof wall in the working face area is not entirely flat; there are areas where the roof can leak. In these leaking areas, the top of the hydraulic support cannot fully contact the roof wall. Therefore, under the influence of gravity, the roof support is prone to tilting, falling over, and biting, affecting the stability and safety of underground operations.

[0004] Therefore, there is a need to provide a hydraulic support system to solve the problems existing in the prior art. Utility Model Content

[0011] The first connecting ear, the second connecting ear, and the third connecting ear are all formed with mounting holes, and the first connecting shaft, the second connecting shaft, and the third connecting shaft are assembled with the mounting holes; the horizontal height of the mounting hole of the third connecting ear is lower than that of the mounting holes of the first connecting ear and the second connecting ear.

[0016] Compared with existing technologies, the hydraulic support system provided by this utility model has the following advantages:

[0017] The hydraulic support system provided by this utility model includes a first support, a second support, and a connecting mechanism; the connecting mechanism includes a first connecting component, a second connecting component, and a third connecting component; the first support and the second support are arranged adjacent to each other, and the two ends of the first connecting component are respectively connected to the first position of the first support and the second support; the two ends of the second connecting component are respectively connected to the second position of the first support and the second support; the two ends of the third connecting component are respectively connected to the third position of the first support and the second support.

[0018] Analysis shows that arranging the first and second supports adjacent to each other facilitates the connection and installation of the connecting mechanism. The connecting mechanism provided in this application includes a first connecting component, a second connecting component, and a third connecting component.

The first position is located in the front end region of the first and second supports, the third position is located in the rear end region of the first and second supports, and the second position is located between the first and third positions. Therefore, by connecting the front, middle, and rear positions, adjacent first and second supports can be connected in series to form a complete hydraulic support system. Since the center of gravity of the complete hydraulic support system is located between the first and second supports, the plumb line drawn from the center of gravity will necessarily be within the end face of the lower support, thus making the complete hydraulic support system more stable and preventing tilting or overturning. Furthermore, since the first and second supports are connected in series as a single structure, the problem of bracket jamming can also be avoided, improving the stability of the system.

[0019] It is understood that the aforementioned "the plumb line is within the end face of the lower support" in this application means that when the first and second supports are connected in series and placed on the slope, the plumb line will not exceed the end face of the support located at the lower position, thereby ensuring the stability of the overall hydraulic support system.

Detailed Implementation

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] like Figure 1 As shown, the hydraulic support system provided by this utility model includes a first support 1, a second support 2, and a connecting mechanism; the connecting mechanism includes a first connecting component 3, a second connecting component 4, and a third connecting component 5; the first support 1 and the second support 2 are arranged adjacent to each other, and the two ends of the first connecting component 3 are respectively connected to the first position of the first support 1 and the second support 2; the two ends of the second connecting component 4 are respectively connected to the second position of the first support 1 and the second support 2; the two ends of the third connecting component 5 are respectively connected to the third position of the first support 1 and the second support 2.

[0033] Compared with existing technologies, the hydraulic support system provided by this utility model has the following advantages:

[0034] The hydraulic support system provided by this utility model facilitates the connection and installation of the connecting mechanism by arranging the first support 1 and the second support 2 adjacent to each other. The connecting mechanism provided by this application includes a first connecting component 3, a second connecting component 4, and a third connecting component 5. The two ends of the first connecting component 3 are respectively connected to the first position of the first support 1 and the second support 2. The two ends of the second connecting component 4 are respectively connected to the second position of the first support 1 and the second support 2. The two ends of the third connecting component 5 are respectively connected to the third position of the first support 1 and the second support 2. The first position mentioned above is located in the front end region of the first support 1 and the second support 2, the third position is located in the rear end region of the first support 1 and the second support 2, and the second position is located between the first position and the third position. Therefore, by connecting the front, middle, and rear positions, the adjacent first support 1 and the second support 2 can be connected in series to form an integrated hydraulic support system. Since the center of gravity of the integrated hydraulic support system is located between the first support 1 and the second support 2, the downward line drawn from the center of gravity must be within the end face of the lower support, thereby making the integrated hydraulic support system more stable and avoiding tilting or overturning problems. Since the first support 1 and the second support 2 are connected in series to form an integral structure, the problem of biting can be avoided, thus improving the stability of the system.

[0035] It is understood that the aforementioned drooping line being located within the end face of the lower support means that when the first support 1 and the second support 2 are connected in series and placed on the slope, the drooping line will not exceed the end face of the support located at the lower position, thereby ensuring the stability of the overall hydraulic support system.

[0036] Optionally, such as Figures 1-5 As shown, the first bracket 1 in this application includes a first base 101, the second bracket 2 includes a second base 201, and the first connecting component 3, the second connecting component 4 and the third connecting component 5 are all connected to the first base 101 and the second base 201.

[0037] The first base 101 and the second base 201 provide stable and sufficient installation space for the first connecting component 3, the second connecting component 4 and the third connecting component 5. The first connecting component 3, the second connecting component 4 and the third connecting component 5 in this application can adopt structures such as rods, shafts or pins, and the connection between the first bracket 1 and the second bracket 2 is achieved by welding the two ends to the corresponding first base 101 and second base 201.

[0038] Optionally, the first connecting component 3 in this application includes a first connecting ear and a first connecting shaft 301. The first connecting ear is formed at the first position of both the first base 101 and the second base 201. The two ends of the first connecting shaft 301 are respectively connected to the first connecting ear on the first base 101 and the second base 201.

[0039] It is understandable that the first connecting ears formed at corresponding positions on the first base 101 and the second base 201 facilitate the connection of the first connecting shaft 301. Furthermore, the first connecting ears can be used in different connection methods. For example, the first connecting shaft 301 can be a pin, with both ends passing through the first connecting ears, and a pin passing through the pin hole at the end of the pin to achieve a stable connection between the first connecting shaft 301 and the first connecting ears. This method allows for a detachable connection of the first connecting shaft 301, enabling the first support 1 and the second support 2 to be quickly separated into independent units for transport when they need to be disassembled and moved, avoiding the problem of excessive size causing transportation difficulties.

[0040] Accordingly, the second connecting component 4 in this application includes a second connecting ear and a second connecting shaft 401. The second connecting ear is formed at the second position of the first base 101 and the second base 201, and the two ends of the second connecting shaft 401 are respectively connected to the second connecting ear on the first base 101 and the second base 201.

[0041] The third connecting component 5 includes a third connecting ear and a third connecting shaft 501. The third connecting ear is formed at the third position of the first base 101 and the second base 201. The two ends of the third connecting shaft 501 are respectively connected to the third connecting ear on the first base 101 and the second base 201.

[0042] The second connecting shaft 401 and the third connecting shaft 501 in this application can both adopt the structure of the first connecting shaft 301 described above, thus realizing the detachable connection between the second connecting shaft 401 and the second connecting ear, and the detachable connection between the third connecting shaft 501 and the third connecting ear, thereby realizing the detachable connection between the first bracket 1 and the second bracket 2.

[0043] It is understood that the first connecting ear, the second connecting ear, and the third connecting ear in this application are all formed with mounting holes. In some embodiments, the first connecting shaft 301, the second connecting shaft 401, and the third connecting shaft 501 are assembled with the mounting holes. The horizontal height of the mounting hole of the third connecting ear is lower than that of the mounting holes of the first connecting ear and the second connecting ear.

[0044] like Figure 5As shown, the horizontal height of the mounting hole formed by the third connecting ear at the rear end in this application is lower than the mounting hole height of the first connecting ear and the second connecting ear, thereby enabling three-point positioning that is not on the same straight line. That is, after the first connecting component 3, the second connecting component 4 and the third connecting component 5 rigidly connect the first bracket 1 and the second bracket 2, since the horizontal height of the three connection positions is different, the problem of the first base 101 and the second base 201 shrinking towards each other due to pressure can be avoided to a certain extent, thereby ensuring the connection stability of the first bracket 1 and the second bracket 2.

[0045] Preferably, in this application, the mounting holes of the first connecting ear and the second connecting ear can be located on the same straight line, or the center of the mounting hole of the second connecting ear can be higher than the center of the mounting hole of the first connecting ear, thereby forming a connection state that gradually rises from the front end of the first base 101 and the second base 201 to the rear end. This provides a more stable support force after connection, so as to avoid the problem of the first bracket 1 and the second bracket 2 being compressed and shrinking, which would damage the first connecting component 3, the second connecting component 4 and the third connecting component 5.

[0046] More preferably, the first connecting component 3 in this application further includes a first connecting sleeve, the second connecting component 4 further includes a second connecting sleeve, and the third connecting component 5 further includes a third connecting sleeve; the first connecting sleeve is connected to the first connecting ear, the first connecting sleeve is located at the end of the first connecting shaft 301, and is sleeved on the outside of the first connecting shaft 301, and the first connecting shaft 301 and the first connecting sleeve are slidably connected; the second connecting sleeve is connected to the second connecting ear, the second connecting sleeve is located at the end of the second connecting shaft 401, and is sleeved on the outside of the second connecting shaft 401, and the second connecting shaft 401 and the second connecting sleeve are slidably connected; the third connecting sleeve is connected to the third connecting ear, the third connecting sleeve is located at the end of the third connecting shaft 501, and is sleeved on the outside of the third connecting shaft 501, and the third connecting shaft 501 and the third connecting sleeve are slidably connected.

[0047] In this embodiment, the first connecting sleeve can be welded to the first connecting ear or connected by threads to achieve a detachable connection between the first connecting sleeve and the first connecting ear. Correspondingly, the second connecting sleeve and the second connecting ear, and the third connecting sleeve and the third connecting ear can all be connected in this way to achieve a detachable connection between the first bracket 1 and the second bracket 2.

[0048] In this embodiment, the distance between the two first connecting ears is greater than the length of the first connecting shaft 301, the distance between the second connecting ears is greater than the length of the second connecting shaft 401, and the distance between the third connecting ears is greater than the length of the third connecting shaft 501. After assembling the first connecting sleeve, the second connecting sleeve, and the third connecting sleeve, the first connecting shaft 301, the second connecting shaft 401, and the third connecting shaft 501 can be connected to the first connecting ears, the second connecting ears, and the third connecting ears. Furthermore, since the first connecting shaft 301 is slidably connected to the first connecting sleeve, the second connecting shaft 401 is slidably connected to the second connecting sleeve, and the third connecting shaft 501 is slidably connected to the third connecting sleeve, when the distance between the first bracket 1 and the second bracket 2 decreases, the relative sliding of the first connecting shaft 301, the second connecting shaft 401, and the third connecting shaft 501 relative to the first connecting sleeve, the second connecting sleeve, and the third connecting sleeve can be used to achieve a small-amplitude movement of the first bracket 1 and the second bracket 2, thereby avoiding damage to the first connecting ears, the second connecting ears, and the third connecting ears.

[0049] Optionally, to ensure connection strength, the diameters of the first connecting shaft 301, the second connecting shaft 401, and the third connecting shaft 501 in this application are not less than 100 mm.

[0050] Optionally, such as Figure 1 Combination Figure 5 As shown, the first bracket 1 and the second bracket 2 in this application also include a lifting mechanism 6 and a support mechanism 7. The lifting mechanism 6 is disposed on the first base 101 and the second base 201, and the telescopic end of the lifting mechanism 6 is connected to the support mechanism 7. The support mechanism 7 extends in the horizontal direction, and a flat support surface is formed on the side away from the lifting mechanism 6.

[0051] The lifting mechanism 6 in this application is a hydraulic cylinder. The hydraulic cylinder can realize the raising and lowering of the support mechanism 7. When the first support 1 and the second support 2 are in place, the extension of the hydraulic cylinder is used to realize the lifting of the support mechanism 7 until it abuts against the top wall of the working surface, thus completing the support of the top wall.

[0052] Preferably, such as Figure 5 As shown, the support mechanism 7 in this application includes a support component 701 and an extension component; the telescopic end of the lifting mechanism 6 is connected to the support component 701, and the extension component includes an extension arm 702 and a drive member 703. One end of the extension arm 702 is rotatably connected to the support component 701, and one end of the drive member 703 is rotatably connected to the support component 701, and the other end is rotatably connected to the extension arm 702. The extension and retraction of the drive member 703 can drive the extension arm 702 to rotate relative to the support component 701.

[0053] The support component 701 in this application is a support arm, which is connected to the telescopic end of the lifting mechanism 6 mentioned above and plays the main supporting role. The extension arm 702, which is further connected, and the drive component 703, which can drive the extension arm 702 to rotate relative to the support component 701, can further increase the support area of ​​the overall support mechanism 7, ensure the support effect, and improve the safety of operation.

[0054] 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.
