Description

Technical Field

[0001] This utility model belongs to the field of tunneling and anchoring machine technology, specifically relating to a six-arm tunneling and anchoring machine with lower support. Background Technology

[0002] Due to varying geological conditions, underground coal mine roadways employ different excavation techniques, such as "one excavation, one anchor" and "long-distance excavation with long anchors."

[0003] Currently, the market is dominated by side-sliding two-arm roadheader-anchor rigs. Compared to tunneling machines, they not only have tunneling and support functions, but their side support systems can also work asynchronously, making them more flexible to operate. However, their efficiency is lower than that of a tunneling machine combined with a single-arm anchor drill. Chinese invention patent application number 202110251318.7 discloses a six-arm roadheader-anchor rig, which is more efficient than the two-arm roadheader-anchor rig, and the efficiency improvement is more significant under the long-step, long-anchoring process. However, the side anchor bolt support of the above-mentioned six-arm roadheader-anchor rig can only support the upper side anchor bolts above a certain height, and cannot support the lower side anchor bolts. For coal mine conditions where side anchors need to be supported in a timely manner, the side anchor bolt machine of the above-mentioned six-arm roadheader-anchor rig almost loses its support function.

[0004] In order to balance the efficiency of tunneling and roadway support, make full use of each drill arm, and meet the needs of coal mine lower rib support, a six-arm tunneling and anchoring machine with lower rib support is needed. Utility Model Content

[0029] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] Please refer to the following: Figures 1 to 8 This invention provides a six-arm tunneling and anchoring machine with under-slope support. The six-arm tunneling and anchoring machine with under-slope support includes a machine body and an under-slope anchoring drill assembly. The under-slope anchoring drill assembly includes an under-slope anchoring lifting frame 122, an under-slope anchoring lifting platform 127, an under-slope anchoring drill 123, and a rotary drive component. The under-slope anchoring lifting frame 122 is connected to the side of the machine body, and its bottom is close to the bottom of the roadway. The under-slope anchoring lifting platform 127 slides along the height direction with the under-slope anchoring lifting frame 122. The rotary drive component is connected to the under-slope anchoring lifting platform 127, and its rotary drive end is connected to the side of the under-slope anchoring drill 123 to drive the under-slope anchoring drill 123 to swing up and down.

[0031] This utility model provides a six-arm anchor drilling machine with lower side support. Compared with the prior art, when it is necessary to support the side of the roadway with anchor bolts, the rotary drive component can rotate the side anchor bolt drill 123 from a vertical state to a horizontal state. Through the sliding cooperation between the side anchor lifting platform 127 and the side anchor lifting frame 122, the side anchor bolt drill 123 can move up and down, thereby facilitating the support of the upper and lower positions of the roadway side and increasing the support range of the side anchor bolt drill 123. By driving the side anchor bolt drill 123 to rotate through the rotary drive component, the side anchor bolt drill 123 can be used to support the anchor bolts at a preset angle.

[0032] In some embodiments, such as Figures 1 to 8 As shown, there is at least one pair of anchor bolt drilling assemblies, with each pair of anchor bolt drilling assemblies respectively located on both sides of the rear of the machine body. The rear of the machine body is provided with a rear support section 7, which includes a support frame and a fixing frame. The anchor bolt drilling assembly also includes an anchor bolt telescopic arm 121 connected to the fixing frame, the telescopic direction of which is parallel to the forward direction of the machine body. The telescopic end of the anchor bolt telescopic arm 121 is connected to the anchor bolt lifting frame 122. The anchor bolt drilling assembly is located below and behind the rear support section 7.

[0033] It should be noted that the support frame is hinged to the fixed frame. When excavating forward, the support frame is retracted upward, at which point the support frame is separated from the ground. When support is needed, the support frame is rotated downward to the position in contact with the ground, at which point the support frame can play a supporting role.

[0034] By installing anchor bolt drilling assemblies on both sides of the tail of the machine body, anchor bolt support can be provided for the side walls on both sides of the roadway. The anchor bolt lifting frame 122 is connected to the fixed frame through the anchor bolt telescopic arm 121. The horizontal position of the anchor bolt lifting frame 122 can be adjusted by the telescopic movement of the anchor bolt telescopic arm 121, thereby facilitating the increase of the anchor bolt support range of the anchor bolt drilling rig 123.

[0035] In addition, the large space at the rear of the machine body allows for the installation height of the side bolt drilling rig assembly to be reduced, which in turn facilitates bolt support at different heights on the roadway sidewall.

[0036] In some embodiments, such as Figures 1 to 8 As shown, the anchor lifting frame 122 has a vertically arranged guide rail, and the anchor lifting platform 127 has a sliding groove that slides with the guide rail; the anchor lifting frame 122 is connected to a lifting drive component, and the lifting end of the lifting drive component is connected to the anchor lifting platform 127.

[0037] It should be noted that the anchor lifting platform 127 slides with the anchor lifting frame 122 through the sliding groove, which can guide the sliding direction of the anchor lifting platform 127 and keep the lateral distance between the anchor lifting platform 127 and the anchor lifting frame 122 relatively fixed. Therefore, during the lifting and lowering process of the anchor lifting platform 127, the anchor lifting platform 127 will not detach from the anchor lifting frame 122.

[0038] For example, the lifting drive component includes a double-speed hydraulic cylinder 126, the cylinder body of which is fixed on the anchor lifting frame 122, and the lifting end of the double-speed hydraulic cylinder 126 is connected to the anchor lifting platform 127. By extending and retracting the lifting end of the double-speed hydraulic cylinder 126, the lifting and lowering movement of the anchor lifting platform 127 can be driven, thereby adjusting the height of the anchor drilling rig 123.

[0039] In some embodiments, such as Figures 1 to 8 As shown, the anchor lifting platform 127 includes a lifting part and a rotating part. The lifting part of the anchor lifting platform 127 is slidably engaged with the anchor lifting frame 122. The anchor drilling machine 123 is slidably disposed on the rotating part of the anchor lifting platform 127, and the sliding direction is along the length direction of the anchor drilling machine 123. The rotary drive component is connected to the lifting part, and the rotary drive end of the rotary drive component is connected to the rotating part.

[0040] It should be noted that the rotary drive component includes a rocking bolt swing cylinder 125. The cylinder body of the rocking bolt swing cylinder 125 is fixed to the lifting part of the rocking bolt lifting platform 127, and the rotary drive end of the rocking bolt swing cylinder 125 is connected to the rotating part of the rocking bolt lifting platform 127. Through the drive of the rocking bolt swing cylinder 125, the rotating part and the rocking bolt drilling machine 123 can achieve the purpose of rotation. The axis of the rocking bolt swing cylinder is parallel to the forward direction of the machine body, so the rocking bolt drilling machine 123 can rotate around the horizontal axis. The rocking bolt drilling machine 123 can rotate to a vertical state or to a horizontal state. When the rocking bolt drilling machine 123 rotates to a horizontal state, the end of the rocking bolt drilling machine 123 faces the side wall of the roadway, which facilitates the rocking bolt drilling machine 123 to perform anchor bolt support.

[0041] For example, the rotating part of the anchor lifting platform 127 is equipped with an adjusting cylinder 128. The two ends of the adjusting cylinder 128 are respectively hinged to the rotating part and the anchor drilling machine 123. The anchor drilling machine 123 is slidably engaged with the rotating part of the anchor lifting platform 127. By adjusting the extension and retraction of the piston rod of the adjusting cylinder 128, the anchor drilling machine 123 can be driven to slide along its length direction, thereby adjusting the distance between the anchor drilling machine 123 and the roadway sidewall, so as to facilitate the anchor drilling machine 123 to provide anchor support to the roadway sidewall.

[0042] For example, the side anchor drilling rig 123 is connected to the side anchor control panel 124 on the side away from the side anchor swing cylinder 125. After the side anchor drilling rig 123 is in position, the operator can control the side anchor drilling rig 123 to anchor the side wall of the roadway through the control panel.

[0043] In some embodiments, such as Figures 1 to 8 As shown, the machine body includes a cutting section 1, a support working platform 2, a main body 3, a top anchor drilling rig 4, a transport section 6, a rear support section 7, a traveling section 8, a shovel plate section 10, and a temporary support section 11. The cutting section 1 is located on the front side of the main body 3 and is hinged to the front end of the rotary table of the main body 3 along the centerline of the main body 3. The shovel plate section 10 is hinged to the front end of the main body 3 along the centerline of the main body 3. The support working platform 2 is connected to the top of the cutting section 1 and is located in the middle of the cutting section 1. The top anchor drilling rig 4 is connected to the side of the main body 3 and can slide forward to a preset working position. The transport section 6 is located on the main body. 3. The transport section 6 is used to transport materials. The transport section 6 passes through the body section 3 along the center line and enters the body section 3. The front end of the transport section 6 is connected to the front end of the body section 3 by a pin, and the rear end of the transport section 6 is supported by the rear support section 7. The rear support section 7 is located on the rear side of the body section 3. The walking section 8 is located on the side of the body. There are two walking sections 8, which are located on both sides of the body section 3 respectively, and are used to drive the six-arm anchor drilling machine to move as a whole. The shovel plate section 10 is located on the lower front side of the body section 3. The temporary support section 11 is located in the middle of the body section 3 and is installed on the rear support section 7 by bolts. The anchor drilling machine assembly is located on the rear support section 7.

[0044] It should be noted that the machine body also includes an electrical system 5, a hydraulic system 13, and a water system 14. The hydraulic system 13 and the electrical system 5 are connected to the tunneling system and the support system to provide power for their operation. The water system 14 is connected to the tunneling system and the support system to supply water for cooling the motor, dust removal, and drilling slag removal.

[0045] In some embodiments, such as Figures 1 to 8 As shown, the support working platform 2 includes a left flap 21, a middle platform 23, a right flap 24, and a platform sliding seat 26. The platform sliding seat 26 is slidably mounted on the cutting part 1. The middle platform 23 is hinged to the platform sliding seat 26. The left flap 21 and the right flap 24 are respectively hinged to both sides of the middle platform 23.

[0046] It should be noted that the connection between the left flap 21 and the middle platform 23 is the same as the connection between the right flap 24 and the middle platform 23. The connection between the left flap 21 and the middle platform 23 will be used as an example for explanation. A flap cylinder 22 is provided between the middle platform 23 and the left flap 21. The two ends of the flap cylinder 22 are hinged to the middle platform 23 and the left flap 21, respectively. The unfolding and retraction of the left flap 21 are controlled by the flap cylinder 22. When both the left flap 21 and the right flap 24 are unfolded, the left flap 21, the right flap 24, and the middle platform 23 are arranged parallel to each other, forming a large platform. A platform swing cylinder 25 is connected to the platform sliding seat 26. The rotating end of the platform swing cylinder 25 is connected to the middle platform 23. The platform swing cylinder 25 can drive the middle platform 23 to swing, thereby adjusting the angle of the middle platform 23. A platform sliding cylinder 27 is provided between the platform sliding seat 26 and the cutting part 1. The two ends of the platform sliding cylinder 27 are connected to the platform sliding seat 26 and the cutting part 1 respectively. The platform sliding cylinder 27 can drive the platform sliding seat 26 to slide.

[0047] In some embodiments, such as Figures 1 to 8 As shown, the top anchor drilling unit 4 includes a top anchor drilling machine 44, a top anchor lifting frame 43, a top anchor lifting platform 47, and a top anchor sliding seat 42; the top anchor drilling machine 44 is connected to the top anchor lifting platform 47, and the top anchor lifting platform 47 and the top anchor lifting frame 43 are slidably engaged; the top of the top anchor sliding seat 42 has a sliding platform, and the top anchor lifting frame 43 is connected to the sliding platform.

[0048] It should be noted that the top anchor sliding seat 42 is equipped with a top anchor sliding cylinder 48, and the piston rod end of the top anchor sliding cylinder 48 is connected to the top anchor lifting frame 43 to drive the top anchor lifting frame 43 to slide left and right on the top anchor sliding seat 42; the top anchor lifting frame 43 is equipped with a lifting cylinder 46, one end of the lifting cylinder 46 is fixedly connected to the top anchor lifting frame 43, and the other end of the lifting cylinder 46 is connected to the top anchor lifting platform 47, which can realize the lifting function of the top anchor drilling machine 44; there are two top anchor drilling machines 44, and both top anchor drilling machines 44 are connected to the top anchor lifting platform 47; each top anchor drilling machine 44 is equipped with a top anchor operating platform 45, which is installed inside the top anchor drilling machine 44. The operator can control the various actions of the top anchor drilling machine 44 by operating the top anchor operating platform 45.

[0049] For example, the main body 3 is connected to two telescopic booms 9, which are respectively arranged on both sides of the main body 3 and are symmetrical about the center line of the main body 3. The telescopic booms 9 are located on the upper side of the traveling part 8. The bottom end of the top anchor sliding seat 42 is connected to the top anchor swing cylinder 41. The cylinder body of the top anchor swing cylinder 41 is bolted to the front end of the telescopic boom 9. The rotating end of the top anchor swing cylinder 41 is connected to the top anchor sliding seat 42 to drive the top anchor sliding seat 42 to rotate. The top anchor swing cylinder 41 is located on one side of the top anchor sliding seat 42 to realize the deployment and retraction of the top anchor drilling machine 44. The deployment here refers to the two top anchor drilling machines 44 rotating from a position parallel to the forward direction of the machine to a vertical position. The retraction here refers to the two top anchor drilling machines 44 rotating from a vertical position to a parallel position.

[0050] In some embodiments, such as Figures 1 to 8 As shown, the temporary support unit 11 comprises a support platform 111, a support telescopic arm 112, a support cylinder 113, and a fixed base 114. The fixed base 114 is fixed to the fixed frame of the rear support unit 7 by bolts. The bottom end of the support cylinder 113 is hinged to the main body 3, and the top end of the support cylinder 113 is hinged to the middle position of the support telescopic arm 112. The bottom end of the support telescopic arm 112 is hinged to the fixed base 114, and the top end of the support telescopic arm 112 is fixed to the support platform 111. During operation, when the support telescopic arm 112 and the support cylinder 113 extend, the support platform 111 is lifted forward and upward until it reaches the working face.

[0051] Furthermore, the six-arm tunneling and anchoring machine with lower side support of the present invention has high flexibility in support operations. The top anchor bolt and cable drilling machines on both sides can work simultaneously, and the side anchor bolt and cable drilling machines can work simultaneously or independently. The temporary support system can support the roof of the roadway in a timely manner, ensuring the safety of support personnel. Moreover, the temporary support can move forward with the machine. Under the long tunneling and long anchoring process, it can greatly reduce the labor intensity of workers, significantly improve the efficiency of tunneling and support, and improve safety. It can meet the needs of "one tunneling and one anchoring", rapid support process for long tunneling and long anchoring roadways, and lower side anchor bolt support.

[0052] like Figure 1 and Figure 2 As shown, when the tunneling and anchoring machine is in the tunneling state, the support system is in the retracted state. Specifically, the telescopic boom 9 retracts back to the upper side of the traveling section 8, the two top anchor drills 44 rotate to be in the same straight line as the telescopic boom 9, the left flap 21 and the right flap 24 fold onto the middle platform 23 and are close to the cutting section 1, the platform sliding seat 26 slides to the front end so as not to obstruct the view during tunneling, the support cylinder 113 of the temporary support section 11 is lowered to the lowest state, the cutting section 1 operates to cut the material, and the shovel section 10 shovels and loads the material that has fallen from the tunnel. The transportation section 6 realizes the loading and transportation of the material.

[0053] like Figure 3 and Figure 4 As shown, when the tunneling and anchoring machine is stopped, the cutting section 1 and the rear support section 7 touch the ground respectively. The support cylinder 113 of the temporary support section 11 extends and lifts the support telescopic arm 112. The support telescopic arm 112 extends and pushes the support platform 111 forward until the support platform 111 contacts the roof plate. After pressurization reaches the predetermined value, it stops. The telescopic boom 9 extends forward and pushes the top anchor drilling section 4 to extend to the cutting head. Under the drive of the top anchor swing cylinder 41, it rotates 90° and becomes flush with the facing face. The platform of the support working platform 2... The sliding cylinder 27 extends, and the platform sliding seat 26 slides backward, driving the entire support working platform 2 to slide backward. After sliding into position, the platform swing cylinder 25 rotates until the middle platform 23 is horizontal. The flap cylinders 22 extend, with the left flap 21 and right flap 24 unfolding, forming a large working platform with the middle platform 23. The platform sliding cylinder 27 retracts, and the platform sliding seat 26 slides forward, driving the entire support working platform 2 to slide forward to the working position. The workers stand on the support working platform 2 to perform the top anchor bolt and cable support operation. After the support is completed, the workers return from the support working platform 2 to the excavator or the ground. The support working platform 2 returns to the retracted position, and the two top anchor bolt drilling rigs 44 rotate in opposite directions to return to the initial state. The telescopic boom 9 and the temporary support section 11 retract in sequence. At this point, the support system has completed its retraction and is ready for the next cycle.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
