Description

Technical Field

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

[0002] During tunnel construction, in order to prevent excessive deformation or collapse due to poor surrounding rock and instability, during the construction process, it is necessary to install arch frames and form a rigid body with anchor bolts, wire meshes, 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 with different diameters, arch frames of different sizes are required according to the building requirements. When the existing equipment grabs the middle arch frame, the backing plate needs to be replaced, resulting in inability to construct quickly. 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 is difficult to fine-tune, which greatly increases the difficulty of building the arch frame. Summary of the Invention

The middle of the clamping arms is rotationally installed on the fixed seat through bolts. An adjusting telescopic rod is arranged between the bottoms of the two clamping arms. Both ends of the adjusting telescopic rod are rotationally connected to the bottoms of the clamping arms through fixing pins.

[0007] Preferably, the limiting mechanism includes a fixed block and two inclined plates. A plurality of round holes and a plurality of annular holes are formed inside the fixed block. A sliding rod is slidably connected to the middle of the round hole. A spring is fixedly installed inside the annular hole. The inclined plate is fixedly connected to the sliding rod and the spring on the same side. Two air ducts are formed at the center inside the fixed block. A push rod is slidably connected to the top end of the air duct. The bottom end of the air duct is communicated with a trachea. The push rod is fixedly connected to the inclined plate.

[0008] Preferably, the fine-tuning mechanism includes a plurality of transmission rods, a driving motor I, and a driving motor II. A rubber wheel is fixedly connected to the middle of the transmission rod. Belt pulleys are fixedly connected to both the front and rear ends of the transmission rod.

[0009] Preferably, the pulley is located inside the slide rail. The two fixed seats are fixedly connected to the bottom surface of the U-shaped plate. The driving motor I is fixedly connected to the U-shaped plate.

[0010] Preferably, the fixed block is fixedly connected to the inner wall of the U-shaped plate. The plurality of transmission rods are rotationally connected to the fixed block.

[0011] Preferably, the rubber wheel is exposed on the surface of the fixed block. Compressed gas is filled inside the air duct and the trachea.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. In the present invention, a plurality of sliding rods are slidably connected between the inclined plate and the fixed block, and a plurality of springs are fixedly installed. When the arch frame is placed between the two inclined plates, the arch frame will squeeze the inclined plates to move to both sides until the lower surface of the arch frame contacts the rubber wheel.

[0014] 2. The present invention drives the second driving motor to operate, driving the spur gear to rotate forward. The spur gear drives the tooth block to move. The tooth block moves forward, thus squeezing the gas inside the front air duct and trachea. The gas inside the air duct will push the push rod to move. The push rod will push the arch frame to move backward. The space between the rear air duct and trachea will increase, making it easier for the arch frame to move backward. When the second driving motor operates to drive the spur gear to rotate backward, it will push the arch frame to move forward, thereby performing fine adjustment of the arch frame back and forth, thus solving the problem that the existing equipment can only perform large-scale back-and-forth adjustment through the grasping arm and is difficult to perform fine back-and-forth adjustment.

[0015] 3. The present invention drives the telescopic rod to shorten to drive the clamping arm to open appropriately. When the first driving motor operates, it drives the driving gear to rotate forward. The driving gear drives the rightmost rubber wheel to rotate. Through the transmission of multiple driven gears and belts, multiple rubber wheels rotate in the same direction, thereby driving the upper arch frame to move to the left. When the first driving motor operates to drive the driving gear to rotate backward, it drives the arch frame to move to the right, thus solving the problem that the existing equipment cannot move the middle arch frame left and right and perform left and right fine adjustment.

[0028] 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 of the two slide rails 51, the back of the bottom rectangular rod 52 is fixedly connected to a bottom plate 53, 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, and a limiting mechanism 7 and a fine adjustment 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 is relatively clamped, the main telescopic rod 54 extends, driving the sliding frame 55 to move upward, driving the middle arch to move until the top of the mine roadway.

[0029] 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 rear 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. Both ends of the adjusting telescopic rod 65 are rotatably connected to the bottom ends of the clamping arms 62 through the fixing pins 64. The limiting mechanism 7 includes a fixed block 71 and two inclined plates 76. A plurality of round holes 72 and a plurality of annular holes 73 are formed inside the fixed block 71. A sliding rod 74 is slidably connected to the middle of the round hole 72. A spring 75 is fixedly installed inside the annular hole 73. The inclined plate 76 is fixedly connected to the sliding rod 74 and the spring 75 on the same side. Two air channels 77 are formed at the center inside the fixed block 71. 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 through the sliding connection of a plurality of sliding rods 74 and the fixed installation of a plurality of springs 75 between the inclined plate 76 and the fixed block 71, when the arch is placed between the two inclined plates 76, the arch will squeeze the inclined plate 76 to move to both sides until the lower surface of the arch contacts the rubber wheel 82. At this time, by extending the adjusting telescopic rod 65 to clamp the clamping arms 62, archs of different sizes can be quickly clamped, thus solving the problem that when the existing equipment grabs medium archs of different sizes, the cushion plate needs to be replaced, resulting in the inability to construct quickly.

[0030] 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 belt 84 is connected in transmission between adjacent belt pulleys 83. A driven gear 85 is fixedly installed on the rightmost 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 straight gear 89 is fixedly installed on the output shaft of the second driving motor 88. A tooth block 810 is meshed with the left side of the straight gear 89. Its function is that by shortening the adjusting telescopic rod 65 to drive the clamping arms 62 to open appropriately, 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, a plurality of rubber wheels 82 will rotate in the same direction, thereby driving the upper arch to move to the left. When the first driving motor 86 works to drive the driving gear 87 to rotate in reverse, the arch will be driven to move to the right, thus solving the problem that the existing equipment can only perform large-scale front and rear adjustment through the grabbing arm and is difficult to perform front and rear fine-tuning.

[0031] Among them, the pulley 56 is located inside the slide rail 51. 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 both 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. The air channels 77 and the air pipe 79 are filled with compressed gas. 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 and drives the spur gear 89 to rotate in reverse, it will push the arch frame to move forward, thereby performing fine adjustment of the arch frame back and forth, thus solving the problem that the existing equipment cannot move the middle arch frame left and right and perform left and right fine adjustment.

[0032] Working principle:

[0033] Lift the middle lifting mechanism 5 upright. After using the electric winch to release the steel wire rope for auxiliary lifting, 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 middle arch frame between the two inclined plates 76. The inclined plates 76 will move to both sides under the pressure of the arch frame, thereby causing the inclined plates 76 to squeeze the springs 75. The lower surface of the arch frame contacts the rubber wheel 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, causing the arch frame to be relatively clamped. The main telescopic rod 54 extends, driving the sliding frame 55 to move upward until it reaches the top of the mine roadway.

[0034] The second driving motor 88 works, 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, 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 and drives the spur gear 89 to rotate in reverse, it will push the arch frame to move forward, thereby performing fine adjustment of the arch frame back and forth.

[0035] The adjustment of the telescopic rod 65 to shorten drives the clamping arm 62 to open appropriately. When the first driving motor 86 operates, it drives the driving gear 87 to rotate forward. The driving gear 87 drives the rightmost rubber wheel 82 to rotate. Through the transmission of multiple driven gears 85 and the belt 84, multiple 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 operates to drive the driving gear 87 to rotate in reverse, the arch frame is driven to move to the right;

[0036] By adjusting the position of the middle arch frame, the user then controls the left and right manipulators 4 to perform corresponding coordinated operations, thereby quickly completing the docking and installation of the arch frame.
