Description

Technical Field

[0001] This invention relates to the field of coal mine tunneling support, and more specifically, to coal mine tunneling support systems and installation equipment. Background Technology

[0002] In coal mining, anchor bolts are used for support operations. Currently, anchor bolt installation is accomplished using automated anchor bolt drilling equipment. These drilling machines are often equipped with anchor bolt chambers to facilitate continuous anchor bolt installation. However, most anchor bolt chambers are disc-shaped, meaning they can only hold one ring of anchor bolts. This results in a limited storage capacity, low overall space utilization, and low efficiency for continuous operation. Consequently, the frequency of downtime for reloading anchor bolts increases, further reducing overall work efficiency.

[0003] For example, the "Anchor Bolt Storage Mechanism and Anchor Bolt Drilling Rig" disclosed in Chinese Invention Patent (Application No.: CN202110773714.6) includes an anchor bolt storage mechanism comprising: a fixed support, a wheel device, a first drive device, and a gripping device; the fixed support has an mounting portion for connecting the anchor bolt drilling rig; the wheel device is disposed on the fixed support for simultaneously storing multiple anchor bolts; the first drive device is disposed on the fixed support and is drively connected to the wheel device for driving the wheel device to rotate, thereby changing the position of the multiple anchor bolts; the gripping device is disposed on the fixed support for gripping the anchor bolts on the wheel device and transferring them to a designated position. This embodiment of the anchor bolt storage mechanism can automatically install anchor bolts and can simultaneously store multiple anchor bolts, improving the efficiency of anchor bolt operations and saving labor; the aforementioned patent can corroborate the deficiencies of the prior art.

[0004] Therefore, we have made improvements to this and proposed a coal mine tunneling support system and installation equipment. Summary of the Invention

[0005] The purpose of this invention is to address the issue that most anchor bolt drilling equipment currently uses a disc-shaped design for its anchor bolt chamber. This results in the anchor bolt chamber only being able to hold one ring of anchor bolts, with the anchor bolts arranged in a ring shape. This limits the number of anchor bolts that can be stored, leading to low overall space utilization, low efficiency in continuous operation, and a corresponding increase in the frequency of needing to stop the machine to load anchor bolts, thus reducing work efficiency.

[0006] To achieve the above-mentioned objectives, the present invention provides the following coal mining tunneling support system and installation equipment to improve the aforementioned problems.

[0007] The application is as follows:

[0008] Coal mining support systems include:

[0009] Steel support structure, used to support the roof grid of coal mining face;

[0010] Anchor bolts and cable anchors are used to enhance the stability of the support structure;

[0011] The safety monitoring system is used to monitor changes in the deformation of the support structure, coal seam gas concentration, and ground stress in real time.

[0012] The early warning and alarm system triggers corresponding alarms and emergency measures based on the early warning thresholds set by the monitoring data.

[0013] The remote monitoring and data analysis system transmits monitoring data to the monitoring center for real-time monitoring and data analysis.

[0014] As a preferred technical solution of this application, the steel bracket support structure is made of high-strength steel.

[0015] As a preferred technical solution of this application, the anchor bolt and anchor cable support device are made of high-strength and durable materials.

[0016] As a preferred technical solution of this application, the safety monitoring system includes a displacement sensor, a gas concentration sensor, and a ground stress monitoring device, which are used to monitor the deformation of the support structure, the coal seam gas concentration, and the changes in ground stress in real time.

[0017] As a preferred technical solution of this application, the early warning and alarm system sets an early warning threshold based on monitoring data. Once the early warning threshold is exceeded, a corresponding alarm is issued and emergency measures are triggered.

[0018] A coal mine tunneling support installation equipment includes a machine body. A drilling mechanism for drilling anchor bolts is provided on one side of the machine body, and an anchor bolt storage mechanism for storing anchor bolts is provided on the other side of the machine body. A grabbing mechanism for moving the anchor bolts in the anchor bolt storage mechanism to the drilling mechanism and installing them on the drilling rig is provided on the top of the machine body. Several anchor bolts are placed in a vortex on the anchor bolt storage mechanism.

[0019] As a preferred technical solution of this application, the anchor bolt chamber mechanism includes a pair of storage trays installed on the machine body. The storage trays are provided with vortex clamping channels. One end of the storage tray has a linear discharge channel tangent to the vortex clamping channels. The linear discharge channel faces the drilling mechanism. The vortex clamping channels and the linear discharge channel are combined to form a storage channel. A plurality of anchor bolts are sequentially attached to each other in the storage channel, and rollers are provided on the inner wall of the storage channel.

[0020] As a preferred technical solution of this application, the middle part of the anchor bolt chamber mechanism is provided with a discharge assembly for sequentially pushing out the anchor bolts. The discharge assembly includes a power shaft rotatably disposed in the middle of the storage pan. The power shaft is provided with a push plate that contacts the anchor bolt at the inner end of the vortex clamping channel and a drive assembly that drives the push plate to gradually extend with the vortex clamping channel.

[0021] As a preferred technical solution of this application, the push plate component includes a support plate with a cavity and a push plate inserted into the cavity. The outer end of the push plate is in contact with the anchor rod, and the inner end of the push plate is connected to the inner wall of the support plate through a first elastic member.

[0022] As a preferred technical solution of this application, the drive assembly includes an L-shaped piston tube disposed between the inner end of the push plate and the support plate. The two ends of the L-shaped piston tube are sequentially provided with a first piston rod fixed to the push plate and a second piston rod parallel to the power shaft. The power shaft is hollow, and a threaded rod is threaded into the inner cavity at the top of the power shaft. A second elastic element is disposed between the top end of the threaded rod and the top inner wall of the power shaft. A guide rod extending into the power shaft is fixed on the machine body. The bottom of the guide rod is inserted and connected to the threaded rod. A pressing rod is rotatably connected to the bottom end of the threaded rod. The pressing rod passes through the power shaft and is opposite to the end of the second piston rod.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] In the scheme of this application:

[0025] 1. In order to solve the problem of the limited number of anchor bolts that can be stored in the existing anchor bolt bin, this application improves the number of anchor bolts that can be stored by setting up an anchor bolt bin mechanism, which includes a storage tray installed on the machine body and a vortex clamping channel on the storage tray;

[0026] 2. By using the set discharge component, the anchor rods in the vortex clamping channel are pushed out by pushing, realizing the automatic discharge of the anchor rods and facilitating the installation of the anchor rods;

[0027] 3. With the push plate component, the push plate component can automatically extend along the vortex clamping channel during the anchor bolt discharge process, which improves the automation level of the device;

[0028] 4. Through the set drive component, during the synchronous movement of the push plate component driven by the rotation of the power shaft, the threaded rod moves upward, driving the second piston rod to move upward, which in turn pushes the first piston rod to move outward, thus pushing the push plate outward, realizing the automatic extension of the push plate component. Only one drive component is needed to drive the rotation of the power shaft to complete the rotation and extension movement of the push plate component, saving equipment costs.

[0029] 5. Through the reset component, the lower pressure rod rotates during the rotation of the power shaft. That is, the rotation relationship between the lower pressure rod and the power shaft is corresponding. After the power shaft rotates a certain number of times and pushes out all the anchor rods, the lower pressure rod can contact the restriction of the threaded rod, so that the threaded rod returns to the initial position, and then the push plate returns to the initial length, so as to repeat the next material discharge operation. At the same time, it is convenient for the loading of anchor rods and avoids the inefficiency of loading anchor rods in the vortex clamping channel of the push plate due to the long restriction.

[0047] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0048] As described in the background section, most anchor bolt drilling equipment currently uses a disc-shaped anchor bolt chamber. This results in the anchor bolt chamber only being able to hold one ring of anchor bolts, with the anchor bolts arranged in a ring shape. This limits the number of anchor bolts that can be stored, leading to low overall space utilization, low efficiency in continuous operation, and a corresponding increase in the frequency of needing to stop the machine to load anchor bolts, thus reducing work efficiency.

[0049] To solve this technical problem, the present invention provides a coal mine tunneling support system and installation equipment, which is applied to the installation of anchor bolts.

[0050] For details, please refer to Figure 1 The coal mining support system specifically includes:

[0051] Steel support structure, used to support the roof grid of coal mining face;

[0052] Anchor bolts and cable anchors are used to enhance the stability of the support structure;

[0053] The safety monitoring system is used to monitor changes in the deformation of the support structure, coal seam gas concentration, and ground stress in real time.

[0054] The early warning and alarm system triggers corresponding alarms and emergency measures based on the early warning thresholds set by the monitoring data.

[0055] The remote monitoring and data analysis system transmits monitoring data to the monitoring center for real-time monitoring and data analysis.

[0056] The steel support structure mentioned above is made of high-strength steel.

[0057] The anchor bolts and anchor cable support devices are made of high-strength and durable materials.

[0058] The safety monitoring system includes displacement sensors, gas concentration sensors, and ground stress monitoring devices, which are used to monitor the deformation of the support structure, the coal seam gas concentration, and changes in ground stress in real time.

[0059] The early warning and alarm system sets early warning thresholds based on monitoring data. Once the early warning threshold is exceeded, a corresponding alarm is issued and emergency measures are triggered.

[0060] The support system can be installed to support coal mine tunnels and monitor them in real time, so that coal mine workers can understand the safety conditions of the working environment in the tunnels and take quick action in the event of an accident.

[0061] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0062] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0063] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0064] Example 1

[0065] Please refer to Figure 2 The coal mine tunneling support installation equipment, specifically, is mainly an installation equipment for anchor bolts in the roadway support system. It includes a machine body 1, a drilling mechanism 2 for drilling anchor bolts on one side of the machine body 1, an anchor bolt storage mechanism 3 for storing anchor bolts on the other side of the machine body 1, and a grabbing mechanism 4 for moving the anchor bolts in the anchor bolt storage to the drilling mechanism 2 and installing them on the drilling rig on the top of the machine body 1. The drilling mechanism 2 and grabbing mechanism 4 mentioned above are similar in principle to the relevant mechanisms in the prior art, and will not be described here.

[0066] For details, please refer to Figure 2 and Figure 3 The anchor bolt storage mechanism 3 includes a pair of storage trays 5 mounted on the machine body 1. The two storage trays 5 are mounted parallel to each other on the machine body 1. The storage trays 5 are provided with a vortex clamping channel 501. One end of the storage tray 5 has a linear discharge channel 502 tangent to the clamping channel. The vortex clamping channel 501 and the linear discharge channel 502 are combined to form a storage channel for storing anchor bolts. The linear discharge channel 502 faces the drilling mechanism 2. Several anchor bolts are sequentially attached to the vortex clamping channel 501 and the linear discharge channel 502. It should be noted that the outer end of the linear discharge channel 502 is provided with an elastic clamp 503 to restrict the anchor bolts. In this embodiment, the anchor bolt has an integral pad, which can restrict it to the storage tray 5.

[0067] By setting up the anchor bolt storage mechanism 3, which includes a storage tray 5 installed on the machine body 1 and a vortex clamping channel 501 on the storage tray 5, the number of anchor bolts stored is increased compared with the anchor bolt storage of existing anchor bolt drilling equipment, and the number of anchor bolts stored is not limited by the circular shape of the annular anchor bolt storage, resulting in better anchor bolt storage effect.

[0068] Example 2

[0069] The coal mine tunneling support installation equipment provided in Example 1 has been further optimized, specifically, as follows: Figure 3 , Figure 4 and Figure 5 As shown, a plurality of rollers 504 are evenly arranged on the inner wall of the vortex clamping channel 501 and the linear discharge channel 502 on the storage tray 5. An elastic bladder 505 (any structure that serves an elastic function can be provided here) is also provided between the rollers 504 and the storage tray 5. Specifically, two elastic bladders 505 are provided in this embodiment, and the combined length of the two elastic bladders 505 is the same as the combined length of the vortex clamping channel 501 and the linear discharge channel 502. By setting the rollers 504, the friction of the anchor rod discharge can be reduced, and the discharge is smoother and more stable. When the friction of the anchor rod discharge is large, the deformation of the elastic bladder 505 allows the rollers 504 to move inward, so that the anchor rod can be discharged smoothly.

[0070] Specifically, the roller 504 is provided with a rotating shaft, and the elastic bladder 505 is provided with a connecting part 506 adapted to the rotating shaft. Several rotating shafts are connected to the elastic bladder 505 as one unit, which facilitates replacement after the component fails.

[0071] Example 3

[0072] The coal mining support installation equipment provided in Example 1 or 2 is further optimized, specifically, as follows: Figure 3As shown, the middle part of the anchor bolt storage mechanism 3 is provided with a discharge assembly for sequentially pushing out anchor bolts. The discharge assembly includes a power shaft 6 rotatably disposed in the middle of the storage tray 5. The power shaft 6 is provided with a push plate 7 that contacts the anchor bolt at the inner end of the vortex clamping channel 501 and a drive assembly 8 that drives the push plate 7 to gradually extend with the vortex clamping channel 501. Through the above-mentioned components, the device can automatically and integratedly discharge the anchor bolts, making the discharge of anchor bolts smoother.

[0073] Specifically, such as Figure 3 and Figure 10 As shown, the push plate component 7 includes a support plate 702 with a cavity and a push plate 701 inserted into the cavity. The support plate 702 is fixed on the power shaft 6. When the power shaft 6 rotates, it can drive the support plate 702 to move synchronously. The outer end of the push plate 701 is in contact with the anchor rod, and the inner end of the push plate 701 is connected to the inner wall of the support plate 702 through the first elastic member 703. The push plate 701 can extend and retract along the support plate 702, which adapts to the characteristics of the vortex clamping channel 501 in this embodiment (the vortex clamping channel 501 increases the distance component between the inside and outside and the center of the storage tray 5, i.e., the power shaft 6).

[0074] Specifically, such as Figure 3 , Figure 7 and Figure 10As shown, the drive assembly 8 includes an L-shaped piston tube 801 disposed between the inner end of the push plate 701 and the support plate 702. A first piston rod 802, fixed to the push plate 701, is disposed at the top end of the L-shaped piston tube 801. In this embodiment, the push plate 701 has a groove in the middle, and the first piston rod 802 is disposed within the groove. A second piston rod 803, parallel to the power shaft 6, is disposed at the bottom end of the L-shaped piston tube 801. The power shaft 6 is hollow, and a threaded rod 804 is threaded into the inner cavity at the top of the power shaft 6. A second elastic element 805 is disposed between the top end of the threaded rod 804 and the inner wall of the top of the power shaft 6. A limiting ring is disposed in the inner cavity at the top of the power shaft 6, and the second elastic element 805 is disposed between the limiting ring and the top end of the threaded rod 804. A guide rod 806 extending into the power shaft 6 is fixed on the body 1. The bottom of the guide rod 806 is inserted into the threaded rod 804. A pressing rod 807 is rotatably connected to the bottom end of the threaded rod 804. A [missing information - likely a component or component] is disposed on the power shaft 6. A slot is provided for the downward pressing rod 807 to move through, and the downward pressing rod 807 passes through the slot and is opposite to the end of the second piston rod 803. During the rotation of the power shaft 6 driven by the drive component 601, the threaded rod 804 cannot rotate due to the restriction of the guide rod 806. Correspondingly, since the threaded rod 804 is threaded inside the power shaft 6, the threaded rod 804 moves linearly with the rotation of the power shaft 6, that is, it moves upward along the inner cavity of the power shaft 6. This drives the downward pressing rod 807 to move upward, squeezing the second piston rod 803. The first piston rod 802 moves outward and drives the push plate 701 to move outward synchronously, that is, to achieve automatic extension along the vortex clamping channel 501 to adapt to the discharge of the anchor rod in the vortex clamping channel 501. The downward pressing rod 807 is rotatably connected to the bottom end of the threaded rod 804, so that the downward pressing rod 807 moves synchronously with the push plate component 7, the L-shaped piston tube 801, and the second piston rod 803, so that this part of the structure can smoothly drive the extension and retraction of the push plate component 7.

[0075] By using the set discharge assembly and push plate 7, the anchor rods in the vortex clamping channel 501 are pushed out by pushing, realizing the automatic discharge of the anchor rods and facilitating the installation of the anchor rods; and the push plate 7 can automatically extend with the vortex clamping channel 501 during the discharge of the anchor rods, which improves the automation level of the device.

[0076] Example 4

[0077] Please refer to Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, it also includes a reset assembly 9 mounted on the power shaft 6 for resetting the push plate 7 after all anchor rods are discharged from the storage tray 5. The reset assembly 9 includes a housing 901 mounted on the top of the power shaft 6. The housing 901 is fixed on the power shaft 6. A pair of drive blocks 902 are movably mounted inside the housing 901. The inner side of the drive blocks 902 is provided with threaded grooves 903 that are adapted to the threaded rod 804. The drive blocks 902 are inserted into the power shaft 6, that is, the power shaft 6 has a drive groove for the drive blocks 902 to pass through, so that the inner arc surface of the drive blocks 902 is aligned with the inner wall of the power shaft 6. During the rotation of the power shaft 6, the drive blocks 902 are synchronized with it, that is, they can drive the threaded rod 804 to make linear movements. It should be noted that the housing 901 has space for the drive blocks 902 to move left and right.

[0078] Specific examples Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the two drive blocks 902 are connected by a linkage assembly 906. A pressure plate 904 is provided at the top of the linkage assembly 906. The pressure plate 904 is sleeved on the drive shaft 6, and several third elastic elements 905 are provided between its bottom end and the housing 901. When the pressure plate 904 presses down, it drives the two drive blocks 902 to move outward synchronously via the linkage assembly 906. The linkage assembly includes a first connecting rod inserted into the housing 901. The sides of the two drive blocks 902 are provided with convex shafts. A second connecting rod is hinged between the rod and the cam shaft. When the lower pressure plate 904 is pressed down, the connecting rod assembly 906 enables the two drive blocks 902 to move outward synchronously. That is, the internal thread 903 of the drive block 902 separates from the threaded rod 804. Correspondingly, under the action of the second elastic element 805, the threaded rod 804 can be reset. The lower pressure plate 904 is reset through the third elastic element 905, which can drive the drive block 902 to reset, that is, return to the threaded engagement relationship with the threaded rod 804.

[0079] Specific examples Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, a first gear 907 is mounted on the power shaft 6, and a second gear 908 meshing with the first gear 907 is mounted on the storage tray 5. The gear ratio between the first gear 907 and the second gear 908 is proportional to the length of the vortex clamping channel 501 and the linear discharge channel 502. A lower pressing block 909 is provided on the outer extension of the second gear 908. When all anchor rods are discharged, the lower pressing block 909 abuts against the lower pressing plate 904 and moves downward. The outer surface of the lower pressing plate 904 is a boss-shaped structure with a wider top and bottom. The lower pressing block 909 is an arc-shaped block with an arc-shaped bottom. When the power shaft 6 rotates to perform the anchor rod discharge operation, the corresponding... The second gear 908 rotates synchronously. When the anchor rod is completely discharged, the lower pressure block 909 presses the lower pressure plate 904, thereby resetting the threaded rod 804 and returning it to its initial position. This causes the push plate 7 to return to its initial length. The arc length of the lower pressure block 909 is proportional to the rotation angle of the power shaft 6. That is, when the push plate 7 returns to its initial position (located at the inner end of the vortex clamping channel 501), the lower pressure block 909 separates from the lower pressure plate 904. Through the above structure and settings, the next discharge operation can be repeated, and the loading of the anchor rod is facilitated, avoiding the impact of the push plate 7 process on the loading efficiency of the anchor rod.

[0080] The usage process of the coal mine tunneling support installation equipment provided by this invention is as follows:

[0081] During operation, the drive unit 601 on the machine body 1 drives the power shaft 6 to rotate intermittently. The push plate 701 rotates synchronously with the power shaft 6, pushing the anchor rod into one station (the station length is the width of the anchor rod, which in this embodiment is the diameter of the pad). Then, the gripping mechanism 4 clamps the anchor rod to the drilling mechanism 2 and installs it on the drilling mechanism 2. Finally, the drilling mechanism 2 drills the anchor rod into the inner wall of the tunnel. During the process of pushing the anchor rod, the power shaft 6 rotates, which correspondingly drives the threaded rod 804 to move upward and squeezes the second elastic element 805. The upward movement of the threaded rod 804 drives the downward pressing rod 807 to move upward and squeeze the second piston rod 803. The first piston rod 802 moves outward and drives the push plate 701 to move outward synchronously. That is, the push plate 701 automatically extends during the rotation of the power shaft 6. At the same time, the power shaft 6 rotates. During the rotation of the force shaft 6, the first gear 907 drives the second gear 908 to rotate, and the rotation of the second gear 908 causes the lower pressure block 909 to move accordingly. When the anchor rod is completely discharged, the lower pressure block 909 presses the lower pressure plate 904, and the third elastic element 905 is compressed. Through the action of the connecting rod assembly 906, the two drive blocks 902 can move outward synchronously, that is, the internal thread 903 of the drive block 902 separates from the threaded rod 804. Under the action of the second elastic element 805, the threaded rod 804 returns to the initial position, which in turn causes the lower pressure rod 807 to return to the initial position and the push plate 7 to return to the initial length. After the lower pressure block 909 separates from the lower pressure plate 904, under the action of the third elastic element 905, the drive block 902 returns to the initial position so as to repeat the next batch of loaded anchor rod discharge work.
