Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and more specifically, to a parallel operation tunneling machine. Background Technology

[0002] Tunnel boring machines are widely used in the excavation of coal mines and mine tunnels, including tunneling operations and roadway roof support operations.

[0003] In related technologies, tunneling operations need to be stopped during support work, but continuous support work cannot be carried out during tunneling operations. In applying these technologies, the inventors discovered at least the following problems: the inability to perform tunneling and roadway roof support work in parallel affects the overall tunneling progress speed. Summary of the Invention

[0004] To address the problem that parallel operations of tunneling and roadway roof support cannot be achieved in related technologies, this invention proposes a parallel operation tunneling machine.

[0005] In view of this, the present invention proposes a parallel operation type tunneling machine, comprising: a machine body; a cutting section disposed on the machine body, the cutting section being used for tunneling operations; and a support device disposed on the machine body, the support device being used to support the roadway roof in the support state; wherein, when the tunneling machine is performing tunneling operations, the support device maintains the support state and moves relative to the roadway roof along the tunneling direction of the machine body.

[0006] The parallel-operation tunneling machine provided by this invention includes a body, a cutting section, and a support device. The cutting section is mounted on the body at its front end and is used for tunneling operations. The support device is mounted on the body and is used for temporary roof support operations in the tunnel. The support device has a supported state and a retracted state; during support operations, the support device is in the supported state. The support operations include installing anchor nets, installing anchor bolts, and erecting roof beams.

[0007] Furthermore, when the tunneling machine is tunneling, the support device can maintain its support status and move relative to the roadway roof along the tunneling direction of the machine, thereby enabling the tunneling operation and the roadway roof support operation to be carried out simultaneously.

[0008] This application involves installing a support device on the body of a tunneling machine, which, when supported, can move relative to the tunnel roof along the tunneling direction of the machine. This allows for simultaneous tunneling operations and tunnel roof support operations, increasing the tunneling speed of the machine and thus improving the excavation efficiency of coal mines and mining tunnels.

[0009] In addition, the parallel operation tunneling machine in the above-mentioned technical solution provided by the present invention may also have the following additional technical features:

[0010] In the above technical solution, the support device includes: a first frame; and a rolling device, which is installed on the first frame and, when the support device is in the support state, the rolling device abuts against the roof of the roadway.

[0011] Preferably, the support device includes a first frame and a rolling device. The first frame supports the rolling device and provides an installation position for the rolling device.

[0012] Furthermore, when the support device is in the supported state, the rolling device abuts against the roadway roof, which allows the support device to roll relative to the roadway roof in the supported state. The tunneling machine can maintain continuous support while tunneling and advancing, realizing parallel operation of tunneling and support without interference, thus improving work efficiency.

[0013] In any of the above technical solutions, the rolling device is a rolling wheel, and there are multiple rolling wheels, which are spaced apart on the first frame.

[0014] Preferably, the rolling device can be a rolling wheel, and there are multiple rolling wheels spaced apart on the first frame. By setting multiple rolling wheels on the first frame, when the support device is in the supported state, the rolling wheels abut against the roadway roof, thereby enabling the support device to roll relative to the roadway roof along the excavation direction of the machine body in the supported state, thus achieving continuous support.

[0015] In any of the above technical solutions, the support device further includes: a shock-absorbing component, which is installed on the first frame and is used to maintain a preset pressure between the rolling wheel and the roadway roof.

[0016] Preferably, the support device also includes a shock-absorbing component. When the tunneling machine is tunneling, the machine body will vibrate. The shock-absorbing component can play a role in shock absorption and displacement compensation when the support device is performing support operations.

[0017] Specifically, the shock-absorbing component is installed on the first frame, which is located between the shock-absorbing component and the tunnel roof. The shock-absorbing component is used to maintain a preset pressure between the rolling wheel and the tunnel roof to achieve the functions of shock absorption and displacement compensation.

[0018] In any of the above technical solutions, the shock absorption component includes: a second frame, spaced apart from the first frame, the second frame being located between the first frame and the body; and an elastic element, disposed between the first frame and the second frame, wherein the elastic element is in a compressed state when the support device is in a supported state.

[0019] Preferably, the shock absorption assembly includes a second frame and an elastic element. Specifically, the second frame is spaced apart from the first frame, and an elastic element is provided between the first and second frames. The elastic element can be a spring, with both ends of the spring abutting against the first and second frames. To ensure the shock absorption effect, multiple springs are used, arranged adjacent to each other. In the supported state, the springs are in a compressed state, and there is a certain pressure surplus between the rolling wheel and the roadway roof.

[0020] In any of the above technical solutions, the support device further includes: a distance sensor, which is disposed on the shock absorption assembly, and the distance sensor is used to detect the distance between the first frame and the second frame.

[0021] Preferably, the support device further includes a distance sensor, which is disposed on the shock absorption assembly and is used to detect the distance between the first frame and the second frame.

[0022] It is understandable that a spring is installed between the first and second supports. By installing a distance sensor in the shock absorption assembly, the degree of spring compression can be measured to ensure that the support device maintains a certain pressure margin between the rolling wheel and the roadway roof under supported conditions. When excessive spring compression is detected, it indicates that the support device is under excessive pressure, which can issue an early warning to remind the workers and ensure operational safety.

[0023] In any of the above technical solutions, the parallel operation tunneling machine further includes: a boom assembly, which is installed on the machine body and connected to the support device. The boom assembly is used to drive the support device to move so that the support device is in a supported state or a retracted state.

[0024] Preferably, the parallel-operation tunneling machine also includes a boom assembly. The boom assembly can move the support device, allowing the support device to extend or retract. Specifically, one end of the boom assembly is located on the machine body, and the other end of the boom assembly is connected to the support device. The boom assembly is used to move the support device so that the support device is in an extended or retracted state.

[0025] In any of the above technical solutions, the outrigger assembly includes: a first outrigger, the first end of which is rotatably connected to the machine body; and a second outrigger, one end of which is rotatably connected to the second end of the first outrigger, and the other end of which is rotatably connected to the support device.

[0026] Preferably, the outrigger assembly includes a first outrigger and a second outrigger, which are rotatably connected to allow the support device to be deployed and retracted. Specifically, a first end of the first outrigger is rotatably connected to the machine body, a second end of the first outrigger is rotatably connected to one end of the second outrigger, and the other end of the second outrigger is rotatably connected to the support device. The deployment and retraction of the support device can be achieved by driving the first and second outriggers.

[0027] In any of the above technical solutions, the parallel operation tunneling machine further includes: a rotating cylinder, which is disposed on the boom assembly and rotatably connected to the support device, and the rotating cylinder is used to drive the support device to rotate relative to the boom assembly.

[0028] Preferably, the parallel-operation tunneling machine also includes a rotary cylinder. The rotary cylinder is used to adjust the angle of the support device so that the rolling wheels of the support device fit snugly against the roadway roof, forming a stable supporting protection. Specifically, the rotary cylinder is installed on the boom assembly and rotatably connected to the support device. By adjusting the angle of the rotary cylinder, the support device can be made to fit snugly against the roadway roof, forming a stable supporting protection to facilitate support operations.

[0029] In any of the above technical solutions, there are multiple support devices, which are arranged along the circumference of the machine body.

[0030] Preferably, there are multiple support devices arranged circumferentially around the machine body. Arranging multiple support devices circumferentially around the machine body ensures effective support during operation, thereby improving the stability of the support protection.

[0031] Furthermore, multiple support devices can be controlled synchronously or independently to adapt to roadways of different shapes, improve the support effect during support operations, and ensure operational safety.

[0032] Additional aspects and advantages of the invention will become apparent in the following description or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0039] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0041] The following reference Figures 1 to 3 A parallel-operation tunneling machine 100 is described according to some embodiments of the present invention.

[0042] like Figures 1 to 3 As shown, the present invention proposes a parallel operation type tunneling machine 100, including: a body 110; a cutting section 120 disposed on the body 110, the cutting section 120 being used for tunneling operations; and a support device 130 disposed on the body 110, the support device 130 being used to support the roadway roof in the support state; wherein, when the tunneling machine 100 is performing tunneling operations, the support device 130 maintains the support state and moves relative to the roadway roof along the tunneling direction of the body 110.

[0043] The parallel-operation tunneling machine 100 provided by this invention includes a body 110, a cutting section 120, and a support device 130. The cutting section 120 is disposed on the body 110, located at the front end of the body 110, and is used for tunneling operations. The support device 130 is disposed on the body 110 and is used for temporary support of the tunnel roof. The support device 130 includes a supported state and a retracted state; during support operations, the support device 130 is in the supported state. The support operations include installing anchor nets, installing anchor bolts, and erecting roof beams, etc.

[0044] Furthermore, when the tunneling machine 100 is performing tunneling operations, the support device 130 can maintain its support status and move relative to the roadway roof along the tunneling direction of the machine body 110, thereby enabling the tunneling operation and the roadway roof support operation to be carried out simultaneously.

[0045] This application provides a support device 130 on the body 110 of a tunneling machine 100, and the support device 130 can move relative to the tunnel roof along the tunneling direction of the body 110 when in a supported state. This allows the tunneling operation of the tunneling machine 100 and the tunnel roof support operation to be carried out simultaneously, increasing the tunneling speed of the tunneling machine 100 and thus improving the excavation efficiency of coal mines and mine tunnels.

[0046] In the above embodiments, such as Figure 1 As shown, the support device 130 includes: a first frame 132; and a rolling device 134, which is disposed on the first frame 132. When the support device 130 is in the support state, the rolling device 134 abuts against the roof of the roadway.

[0047] In this embodiment, the support device 130 includes a first frame 132 and a rolling device 134. The first frame 132 supports the rolling device 134 and provides an installation position for the rolling device 134.

[0048] Furthermore, when the support device 130 is in the support state, the rolling device 134 abuts against the roadway roof, thereby enabling the support device 130 to roll relative to the roadway roof in the support state. The tunneling machine 100 can maintain continuous support while tunneling and advancing, realizing parallel operation of tunneling and support without interference, and improving work efficiency.

[0049] In any of the above embodiments, such as Figure 1 As shown, the rolling device 134 is a rolling wheel 136, and there are multiple rolling wheels 136, which are spaced apart on the first frame 132.

[0050] In this embodiment, the rolling device 134 can be a rolling wheel 136, and there are multiple rolling wheels 136 spaced apart on the first frame 132. By setting multiple rolling wheels 136 on the first frame 132, when the support device 130 is in the support state, the rolling wheels 136 abut against the roadway roof, thereby enabling the support device 130 to roll relative to the roadway roof along the excavation direction of the machine body 110 in the support state, thus achieving continuous support.

[0051] In any of the above embodiments, such as Figure 1 As shown, the support device 130 also includes a shock-absorbing component 140, which is disposed on the first frame 132. The shock-absorbing component 140 is used to maintain a preset pressure between the rolling wheel 136 and the roadway roof.

[0052] In this embodiment, the support device 130 also includes a shock absorption component 140. When the tunneling machine 100 is tunneling, the machine body 110 will vibrate. The shock absorption component 140 can play the role of shock absorption and displacement compensation when the support device 130 is performing support operations.

[0053] Specifically, the shock absorber 140 is disposed on the first frame 132, which is located between the shock absorber 140 and the tunnel roof. The shock absorber 140 is used to maintain a preset pressure between the rolling wheel 136 and the tunnel roof to achieve the functions of shock absorption and displacement compensation.

[0054] In any of the above embodiments, such as Figure 1 As shown, the shock absorption assembly 140 includes: a second frame 142, which is spaced apart from the first frame 132 and is located between the first frame 132 and the body 110; and an elastic member 144, which is disposed between the first frame 132 and the second frame 142 and is in a compressed state when the support device 130 is in a support state.

[0055] In this embodiment, the shock absorption assembly 140 includes a second frame 142 and an elastic element 144. Specifically, the second frame 142 is spaced apart from the first frame 132, and the elastic element 144 is provided between the first frame 132 and the second frame 142. The elastic element 144 can be a spring, and both ends of the spring abut against the first frame 132 and the second frame 142. To ensure the shock absorption effect, there are multiple springs arranged adjacent to each other. In the support state, the springs are in a compressed state, and there is a certain pressure surplus between the rolling wheel 136 and the tunnel roof.

[0056] In practical applications, after the support device 130 is deployed, it enters a support state, forming temporary support protection. During tunneling operations, even if the machine body 110 vibrates, the presence of springs ensures that the supporting force remains constant. Even if the equipment moves back and forth, the support device 130 will still provide support protection. Because the support device 130 always maintains support protection, the anchoring equipment behind the tunneling machine 100 can be deployed and operated simultaneously with the tunneling machine 100, providing a safe parallel working environment.

[0057] In any of the above embodiments, the support device 130 further includes a distance sensor (not shown in the figure), disposed on the shock absorption assembly 140, the distance sensor being used to detect the distance between the first frame 132 and the second frame 142.

[0058] In this embodiment, the support device 130 also includes a distance sensor, which is disposed on the shock absorption assembly 140 and is used to detect the distance between the first frame 132 and the second frame 142.

[0059] It is understood that a spring is installed between the first frame 132 and the second frame 142. By installing a distance measuring sensor in the shock absorption assembly 140, the degree of spring compression can be measured to ensure that the support device 130, in its supported state, maintains a certain pressure margin between the rolling wheel 136 and the roadway roof. When excessive compression of the spring is detected, it indicates that the support device 130 is under excessive pressure, and an early warning can be issued to remind the workers to ensure operational safety.

[0060] In any of the above embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the parallel operation tunneling machine 100 also includes: a boom assembly 150, which is disposed on the machine body 110 and connected to the support device 130. The boom assembly 150 is used to drive the support device 130 to move so that the support device 130 is in a supported state or a retracted state.

[0061] In this embodiment, the parallel-operation tunneling machine 100 also includes a boom assembly 150. The boom assembly 150 can drive the support device 130 to move, allowing the support device 130 to extend or retract. Specifically, one end of the boom assembly 150 is disposed on the machine body 110, and the other end of the boom assembly 150 is connected to the support device 130. The boom assembly 150 is used to drive the support device 130 to move, so that the support device 130 is in a supported state or a retracted state.

[0062] In any of the above embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the outrigger assembly 150 includes: a first outrigger 152, the first end of which is rotatably connected to the body 110; and a second outrigger 154, one end of which is rotatably connected to the second end of the first outrigger 152, and the other end of which is rotatably connected to the support device 130.

[0063] In this embodiment, the support arm assembly 150 includes a first support arm 152 and a second support arm 154, which are rotatably connected to allow the support device 130 to be deployed and retracted. Specifically, a first end of the first support arm 152 is rotatably connected to the body 110, a second end of the first support arm 152 is rotatably connected to one end of the second support arm 154, and the other end of the second support arm 154 is rotatably connected to the support device 130. The deployment and retraction of the support device 130 can be achieved by driving the first support arm 152 and the second support arm 154.

[0064] In practical applications, when the tunneling machine 100 starts working, the posture of the first boom 152 and the second boom 154 is adjusted by the hydraulic cylinders on the tunneling machine 100, changing the angle between the first boom 152 and the second boom 154 and the angle between the first boom 152 and the body 110 of the tunneling machine 100, so that the rolling wheel 136 contacts the roadway roof to form temporary support protection. When the support operation is not required, the posture of the first boom 152 and the second boom 154 can be adjusted by the hydraulic cylinders on the tunneling machine 100 to retract the support device 130 to save space.

[0065] In any of the above embodiments, such as Figure 1 As shown, the parallel operation tunneling machine 100 also includes: a rotating cylinder 160, which is disposed on the boom assembly 150 and rotatably connected to the support device 130. The rotating cylinder 160 is used to drive the support device 130 to rotate relative to the boom assembly 150.

[0066] In this embodiment, the parallel-operation tunneling machine 100 also includes a rotating cylinder 160. The rotating cylinder 160 is used to adjust the angle of the support device 130 so that the rolling wheel 136 of the support device fits well with the roadway roof, forming a stable supporting protection. Specifically, the rotating cylinder 160 is disposed on the boom assembly 150 and rotatably connected to the support device 130. By adjusting the angle of the rotating cylinder 160, the support device 130 can be made to fit well with the roadway roof, forming a stable supporting protection, so as to facilitate support operations.

[0067] In any of the above embodiments, such as Figure 2 and Figure 3 As shown, there are multiple support devices 130, which are arranged circumferentially along the body 110.

[0068] In this embodiment, there are multiple support devices 130, which are arranged circumferentially along the body 110. Arranging multiple support devices 130 circumferentially along the body 110 ensures the support effect of the support operation, thereby improving the stability of the support protection.

[0069] Furthermore, multiple support devices 130 can be controlled synchronously or independently to adapt to roadways 170 of different shapes, thereby improving the support effect during support operations and ensuring operational safety.

[0070] like Figure 2 and Figure 3 As shown, tunnel 170 is an arched tunnel. The tunneling machine 100 includes five support devices 130, which are arranged in a fan shape on the machine body 110. The three support devices 130 on the left side are in the support state, and all five support devices 130 can be independently controlled to extend at different angles.

[0071] In practical applications, the arrangement and quantity of support devices 130 can be determined according to the cross-sectional shape of the roadway 170 in order to achieve a better support effect.
