Description

Technical Field

[0001] The utility model relates to the field of mining and tunnel engineering equipment. Specifically, the utility model relates to a bolt operation device and a bolt jumbo. Background Technique

[0002] After the excavation of a tunnel or roadway, in order to control the appropriate release of the surrounding rock stress and the deformation amount, increase the structural safety factor and facilitate construction, the initial support with a relatively small stiffness and as a part of the permanent bearing structure is immediately implemented after the excavation of the soft surrounding rock tunnel or roadway. Different initial support methods are determined according to different surrounding rock grades. For surrounding rocks of grade IV and above, bolt grouting support is generally adopted during the support process. Bolt grouting support can adopt support methods such as hollow bolts, mortar bolts, self-advancing bolts, and locking foot pipes. Bolt grouting support can provide a certain support stiffness at the initial stage of tunnel excavation. Bolt grouting support can be well combined with steel arch frames, steel wire meshes, and shotcrete to form a combined support and enhance the support effect. The construction process of bolt grouting is as follows: first, the bolt is sent into the bolt hole, and grouting is carried out in the hole to connect the bolt with the surrounding rock mass into one body. The front end of the bolt is welded to the steel arch frame to reinforce the stability of the entire tunnel section.

[0003] During the construction process of roadways and tunnels, at present, manual operation methods are usually adopted for construction operations respectively. However, manual construction not only has a large operation intensity, low construction efficiency, but also has certain safety hazards. Content of the Utility Model

[0029] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0030] During the construction process of mines and tunnels, construction operations such as tunnel drilling, grouting, and anchor rods are usually involved. Currently, manual operations are usually used to carry out the construction operations separately. However, manual construction not only has a high labor intensity, low construction efficiency, but also has certain safety hazards.

[0031] Based on the above problems, please refer to Figures 1 to 3, the embodiment of the present utility model provides a bolter, which is applied to fields such as mines and tunnel engineering. The bolter includes a vehicle body and a bolt operation device 10. The bolt operation device 10 is arranged on the vehicle body and can be used for drilling operations, grouting operations, bolt 11 operations, etc., with high operation efficiency.

[0032] Specifically, the bolt operation device 10 includes an installation carrier 100, a central shaft 200, a working position switching mechanism 300, and a three-station construction mechanism. The central shaft 200 and the working position switching mechanism 300 are both arranged on the installation carrier 100. The three-station construction mechanism is movably arranged on the central shaft 200. The working position switching mechanism 300 is connected to the three-station construction mechanism and is used to drive the three-station construction mechanism to switch construction working positions so as to perform drilling, injecting resin cartridges, and driving bolts respectively.

[0033] In this embodiment, by movably arranging the three-station construction mechanism on the central shaft 200, the working position switching mechanism 300 can drive the three-station construction mechanism to rotate around the axis of the central shaft 200 to achieve the purpose of switching the operation mechanism, that is, drilling, grouting, and bolt construction operations can be sequentially performed on the same position on the inner wall of the tunnel. The construction operation is efficient and effectively guarantees the operation safety of workers.

[0034] Furthermore, the three-station construction mechanism includes a rock drilling mechanism 400, a cartridge feeding mechanism 500, a bolt propulsion mechanism 600, and a driving mechanism 700.

[0035] Among them, the installation carrier 100 is used to connect with the vehicle body. The central shaft 200 and the working position switching mechanism 300 are both arranged on the installation carrier 100. The rock drilling mechanism 400, the cartridge feeding mechanism 500, and the bolt propulsion mechanism 600 are all movably arranged on the central shaft 200. The driving mechanism 700 is arranged on the central shaft 200. The driving mechanism 700 is used to drive the rock drilling mechanism 400 to drill holes in the tunnel, or to drive the bolt propulsion mechanism 600 to drive the bolt 11 to be embedded into the holes. The cartridge feeding mechanism 500 is used to blow resin into the holes. The working position switching mechanism 300 is used to drive the rock drilling mechanism 400, the cartridge feeding mechanism 500, and the bolt propulsion mechanism 600 to rotate around the axis of the central shaft 200.

[0036] In this embodiment, during the construction process, the position of the central shaft 200 is fixed. By movably arranging the rock drilling mechanism 400, the cartridge feeding mechanism 500, and the bolt propulsion mechanism 600 on the central shaft 200, the working position switching mechanism 300 can drive the rock drilling mechanism 400, the cartridge feeding mechanism 500, and the bolt propulsion mechanism 600 to rotate around the axis of the central shaft 200 to achieve the purpose of switching the operation mechanism, that is, drilling, grouting, and bolt 11 construction operations can be sequentially performed on the same position on the inner wall of the tunnel without moving the central shaft 200. The construction operation is efficient and effectively guarantees the operation safety of workers.

[0037] Furthermore, the bolt operating device 10 further includes a propulsion beam 800 rotatably arranged on the central axis 200. The rock drilling mechanism 400, the winding and feeding mechanism 500, and the bolt propulsion mechanism 600 are all arranged on the central axis 200. The station switching mechanism 300 is used to drive the propulsion beam 800 to rotate relative to the axis of the central axis 200.

[0038] In this embodiment, by providing a propulsion beam 800 that can rotate around the axis of the central axis 200, and arranging the rock drilling mechanism 400, the winding and feeding mechanism 500, and the bolt propulsion mechanism 600 on the central axis 200, therefore, driven by the station switching mechanism 300, the propulsion beam 800 can be driven to rotate around the axis of the central axis 200, and thus drive the rock drilling mechanism 400, the winding and feeding mechanism 500, and the bolt propulsion mechanism 600 to rotate relative to the axis of the central axis 200, so as to achieve the purpose of switching stations.

[0039] Furthermore, the propulsion beam 800 is provided with a first guide rail 810 and a second guide rail 820. The rock drilling mechanism 400 is slidably arranged on the first guide rail 810, and the bolt propulsion mechanism 600 is slidably arranged on the second guide rail 820.

[0040] In this embodiment, by providing a first guide rail 810 and a second guide rail 820 on the propulsion beam 800, the rock drilling mechanism 400 can move along the first guide rail 810 under the drive of the drive mechanism 700, so as to complete the rock drilling operation; similarly, the bolt propulsion mechanism 600 can also move along the second guide rail 820 under the drive of the drive mechanism 700, so as to realize that the bolt propulsion mechanism 600 injects the bolt 11 into the hole drilled by the rock drilling mechanism 400.

[0041] It can be understood that the winding and feeding mechanism 500 includes a resin spray pipe and a grouting device. The grouting device is usually arranged on the vehicle body. Through the grouting device, resin cartridges can be conveyed to the resin spray pipe, and the resin spray pipe can be aligned with the hole drilled by the rock drilling mechanism 400 through the station switching mechanism 300, so as to realize the grouting operation.

[0042] It is worth mentioning that the grouting operation is after the drilling operation.

[0043] It should be noted that the drive mechanism 700 includes a drive cylinder. The number of drive cylinders can be one or more, that is, the rock drilling mechanism 400 and the bolt propulsion mechanism 600 can be driven by one drive cylinder, or the rock drilling mechanism 400 and the bolt propulsion mechanism 600 can be driven by multiple drive cylinders respectively. No specific limitation is made here.

[0044] Further, the rock drilling mechanism 400 includes a rock drill 410, a drill pipe 420, and a first sliding member 430. The rock drill 410 is disposed on the first sliding member 430, the drill pipe 420 is disposed on the rock drill 410, the rock drill 410 is used to drive the drill pipe 420 to rotate, the first sliding member 430 is slidably disposed on the first guide rail 810, and the driving mechanism 700 is used to drive the first sliding member 430 to move along the first guide rail 810.

[0045] In this embodiment, one end of the drill pipe 420 is provided with a drill bit, and the other end is connected to the rock drill 410. By driving the drill pipe 420 with the rock drill 410, the drill pipe 420 can be used for rock drilling and hole boring. By driving the first sliding member 430 to move along the first guide rail 810 with the driving mechanism 700, the rock drill 410 can be driven to move along the first guide rail 810, thereby driving the drill pipe 420 to advance relative to the inner wall of the tunnel, and finally holes can be drilled in the inner wall of the tunnel.

[0046] Further, the bolt propulsion mechanism 600 includes a push rod 610 and a second sliding member 620. The push rod 610 is disposed on the second sliding member 620, and the driving mechanism 700 is used to drive the second sliding member 620 to move along the second guide rail 820.

[0047] In this embodiment, when delivering resin cartridges to the holes in the inner wall of the tunnel and waiting for the resin cartridges to solidify, the driving mechanism 700 drives the second sliding member 620 to move along the second guide rail 820 to drive the push rod 610 to move along the second guide rail 820, thereby realizing that the push rod 610 presses and feeds the bolt 11 into the holes in the tunnel, that is, the operation of driving the bolt 11 is realized.

[0048] Further, the bolt operating device 10 further includes a bolt bin 900. The bolt bin 900 is rotatably disposed on the mounting carrier 100. The bolt bin 900 is used to place a plurality of bolts 11. The bolt propulsion mechanism 600 further includes a clamping member 630. The clamping member 630 is used to clamp a bolt 11 from the bolt bin 900. The connection line between the clamping position of the clamping member 630 and the push rod 610 is parallel to the central axis 200.

[0049] In this embodiment, by providing the bolt bin 900, a plurality of bolts 11 can be stored in the bolt bin 900 at one time. Therefore, during the tunnel construction process, it is not necessary to frequently stop the machine to deliver the bolts 11. Only the station switching mechanism 300 needs to drive the propulsion beam 800 to rotate so that the clamping member 630 corresponds to the bolt 11 at the outlet of the bolt bin 900 and clamps the bolt 11 to realize clamping the bolt 11.

[0050] It should be noted that when the bolt 11 is in the clamped state, the push rod 610 can abut against the end of the bolt 11 and push the bolt 11 into the hole in the tunnel under the driving action of the driving mechanism 700.

[0051] Further, one end of the central axis 200 is connected to the driving mechanism 700, and the other end is provided with a telescopic abutting portion 210 for abutting against the inner wall of the tunnel.

[0052] In this embodiment, by providing the abutting portion 210 at one end of the central axis 200, it abuts against the inner wall of the tunnel through the abutting portion during the entire construction process, so as to play a fixing role, ensuring that the rock drilling mechanism 400, the wire feeding and winding mechanism 500, and the bolt propulsion mechanism 600 rotate stably around the central axis 200 under the drive of the station switching mechanism 300, thereby improving the stability of the bolt operating device 10.

[0053] It should be noted that the abutting portion 210 can extend or retract relative to the central axis 200 to adapt to the uneven tunnel face.

[0054] Further, the bolt operating device 10 further includes a wire grabbing arm 1000 provided on the mounting carrier 100, and the wire grabbing arm 1000 is used to grab the iron net and convey it to the wall surface of the tunnel.

[0055] In this embodiment, by providing the wire grabbing arm 1000 on the mounting carrier 100, the iron net can be grabbed by the wire grabbing arm 1000 to the wall surface of the tunnel, thus further improving the construction efficiency of the bolt operating device 10 and increasing the functionality of the bolt operating device 10.

[0056] Further, the bolt operating device 10 further includes a pitching drive mechanism 1100 and a rotation drive mechanism 1200. Both the pitching drive mechanism 1100 and the rotation drive mechanism 1200 are connected to the mounting carrier 100 and are both used to connect to the vehicle body. The pitching drive mechanism 1100 is used to drive the mounting carrier 100 to pitch, and the rotation drive mechanism 1200 is used to drive the mounting carrier 100 to rotate.

[0057] In this embodiment, by providing the pitching drive mechanism 1100 and the rotation drive mechanism 1200 connected to the mounting carrier 100, the pitching drive mechanism 1100 is used to drive the mounting carrier 100 to pitch, and the rotation drive mechanism 1200 drives the mounting carrier 100 to rotate, thereby improving the flexibility of the central axis 200 in the tunnel, enabling drilling, grouting, and bolt 11 operations at any position in the tunnel, and effectively improving the performance of the bolt operating device 10.

[0058] In summary, the embodiment of the present utility model provides an anchor rod working device 10 and an anchor rod trolley. During the construction process, the position of the central shaft 200 is fixed. By movably arranging the rock drilling mechanism 400, the wire feeding and winding mechanism 500, and the anchor rod propulsion mechanism 600 on the central shaft 200, the working mechanism can be switched by driving the rock drilling mechanism 400, the wire feeding and winding mechanism 500, and the anchor rod propulsion mechanism 600 to rotate around the axis of the central shaft 200 through the working position switching mechanism 300. That is, the operations of drilling, grouting, and installing the anchor rod 11 can be sequentially carried out at the same position on the inner wall of the tunnel without moving the central shaft 200. The construction operation is efficient, and the safety of the workers is effectively guaranteed.

[0059] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present utility model should be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
