Description

Technical Field

[0001] This application relates to the technical field of tunnel construction, and particularly relates to a mine arch trolley. Background Art

[0002] In recent years, as China has accelerated the construction of the national comprehensive transportation network, the focus of the highway network has gradually shifted from the eastern coastal areas to the central and western regions. Mountain tunnels have emerged in large numbers on highways. During tunnel construction, in order to prevent the surrounding rock from being poor and unstable, resulting in excessive deformation or collapse, during the construction process, it is necessary to install arch frames and form a rigid body with anchor bolts, wire mesh, connecting steel bars, concrete, etc. to support and maintain the stability of the tunnel.

[0003] Existing mine arch trolleys are usually three-arm arch trolleys and two-arm arch trolleys. Among them, the three-arm arch trolley includes a middle arm and left and right arms. When erecting the arch frame, the left and right arms and the middle arm respectively grab a section of the arch frame for docking. The mine arch trolley can carry a certain number of arch frames into the tunnel for installation, or directly enter the tunnel to install the arch frames that have been transported into the tunnel. It can also assemble the arch frames outside the tunnel and then bring them into the working face of the tunnel for installation. When building arch frames in tunnels of different diameters, arch frames of different sizes are used according to the building requirements. When the existing equipment grabs the middle arch frame, the backing plate needs to be replaced, so rapid construction cannot be achieved. Secondly, when the existing middle arch frame moves upward for docking, the arch frame needs to be moved. The existing equipment can only be adjusted significantly through the grabbing arm, and it is difficult to perform fine adjustment, which greatly increases the difficulty of building the arch frame.

Its function is that the mine arch trolley can carry a certain number of arches into the tunnel interior, and the carried arches are assembled by the left and right manipulators 4 and the intermediate lifting mechanism 5, and then installed at the working face, or the empty trolley enters and installs the arches that have been transported into the tunnel interior; it is also possible to assemble the arches outside the tunnel and then bring them into the working face of the tunnel for installation, thus providing various installation methods for the tunnel arches.

[0020] Please refer to Figures 3 - 7, the intermediate lifting mechanism 5 includes two symmetrically arranged slide rails 51. A plurality of rectangular rods 52 are fixedly connected to the back surfaces of the two slide rails 51. A bottom plate 53 is fixedly connected to the back surface of the bottom rectangular rod 52. A main telescopic rod 54 is fixedly installed above the bottom plate 53. A sliding frame 55 is fixedly installed at the telescopic end of the main telescopic rod 54. A plurality of pulleys 56 are fixedly installed on both the left and right sides of the sliding frame 55. A connecting plate 57 is fixedly installed in the middle of the sliding frame 55. A U-shaped plate 58 is fixedly connected to the front of the connecting plate 57. Clamping mechanisms 6 are fixedly installed on both the left and right sides of the bottom surface of the U-shaped plate 58. A limiting mechanism 7 and a fine-tuning mechanism 8 are arranged on the upper surface of the U-shaped plate 58. Its function is that after the intermediate lifting mechanism 5 is erected and the arch frame is relatively clamped, the main telescopic rod 54 extends, driving the sliding frame 55 to move upward, driving the middle arch frame to move until the top of the mine roadway.

[0021] Among them, the clamping mechanism 6 includes a fixed seat 61, two bolts 63, and two fixing pins 64. Clamping arms 62 are arranged on both the front and back sides of the fixed seat 61. The middle of the clamping arm 62 is rotatably installed on the fixed seat 61 through the bolt 63. An adjusting telescopic rod 65 is arranged between the bottom ends of the two clamping arms 62.

A push rod 78 is slidably connected to the top end of the air channel 77. The bottom end of the air channel 77 is communicated with an air pipe 79. The push rod 78 is fixedly connected to the inclined plate 76. Its function is that a plurality of sliding rods 74 are slidably connected between the inclined plate 76 and the fixed block 71 and a plurality of springs 75 are fixedly installed. When the arch frame is placed between the two inclined plates 76, the arch frame will squeeze the inclined plate 76 to move to both sides until the lower surface of the arch frame contacts the rubber wheel 82. At this time, by extending the adjusting telescopic rod 65 to clamp the clamping arms 62, arch frames of different sizes can be quickly clamped, thus solving the problem that when the existing equipment grabs medium arch frames of different sizes, it is necessary to replace the backing plate, resulting in the inability to construct quickly.

[0022] Among them, the fine-tuning mechanism 8 includes a plurality of transmission rods 81, a first driving motor 86, and a second driving motor 88. A rubber wheel 82 is fixedly connected to the middle of the transmission rod 81. Belt pulleys 83 are fixedly connected to both the front and rear ends of the transmission rod 81.

A driving gear 87 is fixedly installed on the output shaft of the first driving motor 86. The driving gear 87 meshes with the driven gear 85. A spur gear 89 is fixedly installed on the output shaft of the second driving motor 88. A tooth block 810 meshes with the left side of the spur gear 89. Its function is that by adjusting the telescopic rod 65 to shorten, the clamping arm 62 is appropriately opened. When the first driving motor 86 works, it will drive the driving gear 87 to rotate forward. The driving gear 87 will drive the rightmost rubber wheel 82 to rotate. Through the transmission of a plurality of driven gears 85 and the belt 84, the plurality of rubber wheels 82 rotate in the same direction, thereby driving the upper arch frame to move to the left. When the first driving motor 86 works to drive the driving gear 87 to rotate in reverse, the arch frame is driven to move to the right, thus solving the problem that the existing equipment can only perform large-scale front-back adjustment through the grabbing arm and is difficult to perform front-back fine-tuning.

[0023] Among them, the pulley 56 is located inside the slide rail 51. The two fixed seats 61 are fixedly connected to the bottom surface of the U-shaped plate 58. The first driving motor 86 is fixedly connected to the U-shaped plate 58. The fixed block 71 is fixedly connected to the inner wall of the U-shaped plate 58. A plurality of transmission rods 81 are rotatably connected to the fixed block 71. The second driving motor 88 is fixedly connected to the fixed block 71. The front and rear ends of the tooth block 810 are slidably connected to the inner wall of the air pipe 79. The rubber wheel 82 is exposed on the surface of the fixed block 71. Compressed gas is filled in the air channels 77 and the air pipe 79. Its function is that when the second driving motor 88 works, it drives the spur gear 89 to rotate forward. The spur gear 89 will drive the tooth block 810 to move. The tooth block 810 moves forward, thereby squeezing the gas inside the front air channels 77 and the air pipe 79. The gas inside the air channel 77 will push the push rod 78 to move. The push rod 78 will push the arch frame to move backward. The space between the rear air channels 77 and the air pipe 79 will increase, making it easier for the arch frame to move backward. When the second driving motor 88 works to drive the spur gear 89 to rotate in reverse, it will push the arch frame to move forward, thereby performing front-back fine-tuning of the arch frame, thus solving the problem that the existing equipment cannot move the middle arch frame left and right and perform left-right fine-tuning.

[0024] Working principle: Erect the middle lifting mechanism 5. After assisting in lifting by releasing the steel wire rope through the electric winch, use the left and right manipulators 4 to grab and fix the arch frames on both sides. Then, adjust the telescopic rod 65 to shorten, driving the clamping arms 62 to open. Place the arch frame in the middle between the two inclined plates 76. The inclined plates 76 will move to both sides under the pressure of the arch frame, thus causing the inclined plates 76 to squeeze the springs 75. The lower surface of the arch frame contacts the rubber wheels 82. Subsequently, adjust the telescopic rod 65 to extend, causing the clamping arms 62 to clamp. The clamping arms 62 will contact the upper surface of the arch frame, relatively clamping the arch frame. The main telescopic rod 54 extends, driving the sliding frame 55 to move upward until it reaches the top of the mine roadway; The driving motor two 88 operates, driving the spur gear 89 to rotate forward. The spur gear 89 will drive the tooth block 810 to move. The tooth block 810 moves forward, thus squeezing the gas inside the front air duct 77 and the air pipe 79. The gas inside the air duct 77 will push the push rod 78 to move. The push rod 78 will push the arch frame to move backward. The space between the rear air duct 77 and the air pipe 79 will increase, making it easier for the arch frame to move backward. When the driving motor two 88 operates to drive the spur gear 89 to rotate in reverse, it will push the arch frame to move forward, thus performing fine adjustment of the arch frame in the front and back directions; Adjust the telescopic rod 65 to shorten, driving the clamping arms 62 to open appropriately. When the driving motor one 86 operates, it will drive the driving gear 87 to rotate forward. The driving gear 87 will drive the rightmost rubber wheel 82 to rotate. Through the transmission of multiple driven gears 85 and the belt 84, multiple rubber wheels 82 will rotate in the same direction, thus driving the upper arch frame to move to the left. When the driving motor one 86 operates to drive the driving gear 87 to rotate in reverse, it will drive the arch frame to move to the right; By adjusting the position of the middle arch frame, the user then performs corresponding coordinated operations by controlling the left and right manipulators 4, thus quickly completing the docking and installation of the arch frames.
