DETAILED DESCRIPTION
[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.
[0024] Reference below Figures 1 to 4 , describing a temporary support system for an integrated miner and anchor machine with a dynamic adjustment mechanism for the top distance according to an embodiment of the present invention.
[0025] The temporary support system of the anchoring and boring machine with the dynamic adjustment mechanism of the empty-top distance according to the embodiment of the present invention includes a temporary support assembly 1 , a wing-spreading roof assembly 4 and a temporary support member 6 .
[0026] The temporary support assembly 1 includes a main frame 12, with a retractable sliding roof panel 11 at its front end. The wing-spreading roof assembly 4 is located on either side of the sliding roof panel 11. The wing-spreading roof assembly 4 includes an adaptive roof panel 41, one end of which is connected to one side of the sliding roof panel 11. A retractable curved guard plate 45 is provided at the front end of the adaptive roof panel 41. The top end of the temporary support member 6 is connected to the bottom of the sliding roof panel 11.
[0027] When the support system is in operation, the adaptive roof 41 maintains uniform contact with the top coal and rock layer of the tunneling roadway, and the arc-shaped guard plate 45 extends forward to provide advanced support for the empty roof area facing the tunneling working face.
[0028] Both the sliding roof 11 and the arc-shaped guard plate 45 can be extended to the undeveloped area of the tunnel through a telescopic mechanism. The temporary support 6 also has a telescopic mechanism. The specific type of the telescopic mechanism is set according to actual needs, and the telescopic mechanism can be a single-stage or multi-stage telescopic mechanism, and there is no restriction on this. The number of wing-spreading ceiling assemblies 4 is set according to actual needs, and there is no restriction on this. For example, the number of wing-spreading ceiling assemblies 4 is 2, distributed at the left and right ends of the sliding roof 11, providing a larger coverage range in the left and right directions. The adaptive roof 41 maintains uniform contact with the top coal rock layer of the tunneling tunnel, which means that the support force of the adaptive roof 41 on the roof is evenly distributed, and can automatically adjust its own state according to environmental conditions.
[0029] The support system of the embodiment of the present invention needs to be installed on the anchoring and digging machine when in use. The installation method is as follows: the bottom end of the temporary support member 6 is connected to the chassis of the anchoring and digging machine, and the rear end of the temporary support assembly 1 is connected to the frame of the anchoring and digging machine.
[0030] According to the temporary support system of the drilling and anchoring machine with a dynamic adjustment mechanism for the empty top distance according to the embodiment of the present invention, by providing a retractable sliding roof and an arc-shaped guard plate, the temporary support system can be equipped on the drilling and anchoring machine. The sliding roof can be extended to support the coal and rock layer at the top of the excavation face, and the arc-shaped guard plate can be extended into the unsupported empty top area in front of the excavation working face in advance to form a temporary protective barrier, thereby realizing zero empty top distance advance support operation at the head of excavation, improving the adaptability and reliability of underground excavation operations to roof control, and ensuring the safe, stable and efficient operation of the excavation operation.
[0031] like Figure 1 As shown, in some embodiments, the temporary support assembly 1 further includes a support arm 13, a screw adjustment mechanism 14, and a pin 16. The front section of the support arm 13 is fixedly connected to the main frame 12 via multiple pins 16, and the screw adjustment mechanism 14 is disposed at the end of the support arm 13. The support arm 13 and the main frame 12 are detachably connected, and the number and installation position of the pins 16 are selected based on actual needs. The screw adjustment mechanism 14 is provided with a screw 141. By rotating the screw 141, its working length can be adjusted, thereby changing the height and angle of the main frame 12, so that the temporary support assembly better fits the tunnel roof.
[0032] Combine Figure 1 and Figure 2 As shown, the main frame 12 comprises a main box girder structure, a first mounting base 121, side arms 123, and a first-stage front probe 15. The side arms 123 are connected to both sides of the main box girder structure, with their rear sides connected to the support arms 13. The first mounting base 121 is located within the main box girder structure, and the rear end of the first-stage front probe 15 is connected to the first mounting base 121. The first mounting base 121 is detachably connected to the main box girder structure, facilitating installation and maintenance. The main box girder structure has a rectangular cross-section with a width L. Generally, L is ≤ 800mm, making it suitable for the confined spaces of roadways. The number and type of first-stage front probes 15 are determined based on actual needs and are not limited. For example, two first-stage front probes 15 are arranged side by side to improve reliability. The first-stage front probes 15 are hydraulic cylinders, enabling precise position control to meet high load requirements. The rear section of the side arms 123 extends from the rear of the main box girder structure, forming a U-shaped clearance, thereby reserving space for the installation of the dust collector.
[0033] from Figure 2 It can be seen that a vertically running long hole 122 is provided in the middle of the main box girder structure. The size of the long hole 122 is designed according to actual needs, and a certain space is reserved for anchor cables and anchor rods.
[0034] Combine Figures 1 to 3As shown, in some embodiments, rails 111 are provided on both sides of the rear portion of the sliding top plate 11, and a special-shaped plate with a high middle and low sides is provided at the front end of the sliding top plate 11. The rails 111 are slidably connected to the main box beam structure. A second mounting seat 112 is provided at the bottom of the sliding top plate 11, and a third mounting seat 113 and a ceiling interface 114 are provided at the bottom of both sides of the special-shaped plate. The second mounting seat 112 is connected to the front end of the first-level front probe 15, and the third mounting seat 113 is connected to the top of the temporary support member 6. The shape of the special-shaped plate can better match the wing-spreading ceiling assembly 4 and enhance the support effect. The ceiling interface 114 can be connected to the wing-spreading ceiling assembly 4 by setting a ball joint.
[0035] Combine Figure 1 and Figure 4 As shown, in some embodiments, the wing-spreading roof assembly 4 also includes an inner sleeve 42, a secondary front probe 43, an outer sleeve 44, and a dust curtain 46. The outer sleeve 44 is located in the middle of the adaptive roof panel 41, and the inner sleeve 42 and the outer sleeve 44 are slidably connected. The two ends of the secondary front probe 43 are connected to the inner sleeve 42 and the outer sleeve 44, respectively. A curved guard plate 45 is located at the front end of the inner sleeve 42, and the dust curtain 46 is installed below the curved guard plate 45. The curved outer surface of the curved guard plate 45 is consistent with the curved surface of the formed roadway, providing effective support for the head-on area. The type of the primary front probe 15 is determined according to actual needs and is not limited to this. For example, the secondary front probe 43 is a hydraulic cylinder, which can achieve precise position control to meet high load requirements. In one example, the curved guard plate 45 is hinged to the front end of the inner sleeve 42 and can rotate to a certain angle in the left and right directions, improving its adaptability to different roadway sections and enhancing its fit and coverage. At the same time, the maximum rotation angle is limited to ensure the effectiveness of the support. The maximum rotation angle is designed according to actual needs and is not limited.
[0036] In some embodiments, displacement sensors are provided in the temporary support member 6 and the first-level front exploration member 15 to detect the extended length of each push rod, thereby achieving the matching of the front exploration depth with different mining heights. The front exploration depth can be adjusted through the program to correspond to the mining height parameters, and different mining heights are set with different front exploration depths.
[0037] In the operation process, according to different mining heights, the screw adjustment mechanism 14 and the front exploration extension amounts of the first-level front exploration piece 15 and the second-level front exploration piece 43 are adjusted, that is, there is a certain correspondence between the tunnel height, the effective length of the screw 141, the telescopic length of the first-level front exploration piece 15, and the telescopic length of the second-level front exploration piece 43. When the mining height changes, it is necessary to adjust the extension amount of the screw 141 and the front exploration piece.
[0038] In some embodiments, as Figure 1As shown, the temporary support system for a miner-anchor machine with a dynamic adjustment mechanism for the top-to-bottom distance also includes a net hanging assembly 2, a net storage assembly 3, a net limiting assembly 7, a dust collector interface 5, a transition frame 52, and an air guide duct 53. The net hanging assembly 2, net storage assembly 3, and net limiting assembly 7 are sequentially arranged above the main frame 12 from front to back, used for storing and hanging the anchor net. The dust collector interface 5 is located on the main frame 12 for installing the dust collector. The air guide duct 53 and transition frame 52 are sequentially arranged at the bottom of the main frame 12 from front to back to collect headwind.
