A concrete subgrade reinforcement device for road and bridge construction

Abstract

This application discloses a concrete subgrade reinforcement device for road and bridge construction, belonging to the field of road construction technology. It includes a mobile platform with an electric telescopic rod mounted on its inner side. Two sets of lifting rods are slidably connected to the inner side of the mobile platform. By setting up a circular ring and a hollow column, when the mobile platform moves on steep roads, the rollers drive the L-shaped rod to change with the road surface height. The up-and-down movement of the L-shaped rod drives the circular ring to move up and down, simultaneously moving the rotating plate, thus achieving real-time adjustment of the rotating plate height according to the ground conditions. Starting a motor drives the rotating rod to rotate, and the rotation of the rotating rod causes the lifting rod and the hollow column to rotate together via a transmission belt. A limiting plate keeps the hollow column in its current position, ensuring that the rotation of the lifting rod is not affected while it is moving up and down.

Description

Technical Field

[0001] This application relates to the field of road construction technology, and more specifically, to a concrete subgrade reinforcement device for road and bridge construction. Background Technology

[0002] Currently, my country is vigorously promoting the application of concrete subgrade reinforcement devices for road and bridge construction. The core function of these devices is to proactively improve the stability, bearing capacity, and durability of the subgrade, preventing or repairing defects at their source. Specifically, their functions can be divided into two main categories: 1. Core reinforcement function; 2. Typical applications targeting specific defects.

[0003] Because existing concrete subgrade reinforcement devices for road and bridge construction are inconvenient to use when clearing gravel and other debris from the ground, especially on steep terrain, they cannot effectively adjust to the ground height.

[0014] The advantages of this application are: (1) By setting up a circular ring and a hollow column, the rollers will drive the L-shaped rod to change with the height of the road surface when the mobile platform moves on a steep road. The up and down movement of the L-shaped rod drives the circular ring to move up and down at the same time, and drives the rotating plate to move, so as to achieve the purpose of adjusting the height of the rotating plate in real time according to the ground. By starting the motor, the rotating rod is driven to rotate. The rotation of the rotating rod causes the lifting rod and the hollow column to rotate together through the transmission belt.

The rotation of the first reciprocating screw causes the second stacking platform to move up and down along the first reciprocating screw. When the second stacking platform moves down and presses the L-shaped pressing plate, the first stacking platform gradually tilts towards one end of the second stacking platform, causing the debris on the first stacking platform to fall onto the top of the second stacking platform. As the second stacking platform moves up to the opening, the debris on the second stacking platform falls into the groove, thus achieving the purpose of collecting debris.

[0016] (3) This application sets up two rings and three rings so that when the motor two starts, it drives the reciprocating screw two to rotate. Through the rotation of the reciprocating screw two, the ring two moves up and down along the reciprocating screw two. Through the up and down movement of the ring two, the ring three and the four sets of telescopic rods move up and down together. By starting the motor three, the motor three drives the ring four to rotate and at the same time drives the four sets of telescopic rods to rotate together with the ring three, so as to achieve the purpose of the four sets of telescopic rods moving up and down while rotating around the ring three as the center. This allows the debris accumulated in the groove to be processed by the crusher, and the processed debris falling from the discharge port of the crusher can be evenly scattered on the road surface to achieve the purpose of waste utilization.

[0025] Example 1, see Figures 1-3 This embodiment provides a concrete subgrade reinforcement device for road and bridge construction, including a mobile platform 100, an electric telescopic rod 200 mounted on the inner side of the mobile platform 100, and a reinforcement plate 300 mounted below the electric telescopic rod 200. Two sets of lifting rods 101 are slidably connected to the inner side of the mobile platform 100. A rotating plate 102 is fixedly connected below each set of lifting rods 101. A ring 103 is rotatably connected to the outer side of each set of lifting rods 101 and above the mobile platform 100. An L-shaped rod 104 is rotatably connected to the outer side of each set of rings 103. Rollers 105 are rotatably connected to the inner side of the lower part of each set of L-shaped rods 104. The bottom of each set of rollers 105 is on the same horizontal plane as the bottom of each set of rotating plates 102. Both sets of rotating plates 102 are designed with a cross-shaped structure, and their diameters are less than half the distance between the two sets of lifting rods 101. A motor 106 is mounted above the mobile platform 100 and between the two sets of lifting rods 101. A rotating rod 107 is mounted above the motor 106. A ring 103 is rotatably connected to the outer side of each set of lifting rods 101 and above the ring 102. Hollow columns 108 are slidably connected above each of the two sets of lifting rods 101. Two sets of sliding grooves are provided on the outer side of each of the two sets of hollow columns 108 and above the ring 103. Rectangular blocks corresponding to the two sets of sliding grooves are provided on the inner side of each of the two sets of hollow columns 108. Transmission belts 109 are sleeved on the outer side of each of the two sets of hollow columns 108. Transmission belts 109 are sleeved on the outer side of the rotating rod 107. Rectangular plates 110 are fixedly connected above the moving platform 100 and behind each of the two sets of lifting rods 101. Limiting plates 111 are fixedly connected on the outer side of each of the two sets of rectangular plates 110 and on the side near the hollow columns 108. The diameter of the ring above each of the two sets of hollow columns 108 is larger than the diameter of the arc below each of the hollow columns 108. The limiting plates 111 are rotatably connected to the outer side of the ring above each of the two sets of hollow columns 108. This application sets up a circular ring 103 and a hollow column 108 so that when the mobile platform 100 moves on a steep road surface, the roller 105 will drive the L-shaped rod 104 to change with the height of the road surface. The up and down movement of the L-shaped rod 104 drives the circular ring 103 to move up and down, and at the same time drives the rotating plate 102 to move, so as to achieve the purpose of adjusting the height of the rotating plate 102 in real time according to the ground. By starting the motor 106, the rotating rod 107 is driven to rotate. The rotation of the rotating rod 107 causes the lifting rod 101 and the hollow column 108 to rotate together through the transmission belt 109. The limiting plate 111 keeps the hollow column 108 in the current position, so as to achieve the purpose of not affecting the rotation of the lifting rod 101 while it moves up and down.

[0026] In practical use, the above-mentioned equipment utilizes two sets of lifting rods 101 slidably connected to the inner side of the mobile platform 100, with rotating plates 102 fixedly connected below each set of lifting rods 101. The rotation of the lifting rods 101 drives the rotating plates 102 to rotate, thus accumulating gravel and other debris in a straight line. A circular ring 103 is rotatably connected to the outer side of each set of lifting rods 101 and above the mobile platform 100. The up-and-down movement of the circular ring 103 drives the up-and-down movement of the lifting rods 101. Finally, L-shaped rods 104 are rotatably connected to the outer side of each set of circular rings 103. When the L-shaped rod 104 moves up and down, it drives the ring 103 to move. Rollers 105 are rotatably connected to the inner sides of both sets of L-shaped rods 104, and the bottom of both sets of rollers 105 is on the same horizontal plane as the bottom of both sets of rotating plates 102. When the moving platform 100 moves on steep surfaces, the rollers 105 drive the L-shaped rods 104 to change with the road surface height, thus achieving real-time adjustment of the height of the rotating plates 102. A motor 106 is installed above the moving platform 100 and between the two sets of lifting rods 101, and a rotating plate is installed above the motor 106. Rotating rod 107 rotates when motor 106 starts. Hollow columns 108 are slidably connected to the outer sides of the two sets of lifting rods 101 and above the ring 103. Two sets of sliding grooves are provided on the outer sides of the two sets of lifting rods 101 and above the ring 103. Rectangular blocks corresponding to the sliding grooves are provided on the inner sides of the two sets of hollow columns 108. This allows the hollow columns 108 to drive the lifting rods 101 to rotate while the lifting rods 101 can slide up and down through the hollow columns 108. A transmission belt 109 is sleeved on the outer sides of the two sets of hollow columns 108. Furthermore, both sets of transmission belts 109 are sleeved on the outside of the rotating rod 107, so that when the rotating rod 107 rotates, it drives the two sets of hollow columns 108 to rotate. Rectangular plates 110 are fixedly connected above the moving platform 100 and behind the two sets of lifting rods 101. Limiting plates 111 are fixedly connected on the outside of the two sets of rectangular plates 110 and on the side close to the hollow columns 108. The two sets of limiting plates 111 are rotatably connected to the outside of the two sets of hollow columns 108, so that when the lifting rod 101 moves up and down, the hollow columns 108 can always be kept in the original position through the limiting plates 111.

[0027] Example 2, see Figures 1-6In this embodiment, based on Embodiment 1, a housing 201 is fixedly connected to the inner side of the mobile platform 100. A reciprocating screw 204 is rotatably connected to the inner side of the housing 201. A transmission rod 202 is fixedly connected above the reciprocating screw 204 and above the housing 201. A transmission belt 203 is sleeved on the outer side of the transmission rod 202 and the rotating rod 107. A stacking platform 205 is threadedly rotatably connected to the outer side of the reciprocating screw 204. A rotating rod 206 is rotatably connected to the inner side of the housing 201. The outer side of the rotating rod 206 is fixed... A stacking platform 207 is connected to the outside of the stacking platform 207. An L-shaped pressing plate 208 is fixedly connected to the bottom of the stacking platform 207. A spring 209 is fixedly connected between the bottom of the stacking platform 207 and the outer shell 201. An arc-shaped plate 210 is fixedly connected to the outside of the outer shell 201 and to one side of the stacking platform 207. Baffles 211 are fixedly connected to both sides of the arc-shaped plate 210. A round rod 212 is rotatably connected between the two sets of baffles 211. Six sets of sliding plates 213 are fixedly connected to the outside of the round rod 212. A transmission assembly 214 is mounted above the transmission rod 202. The transmission assembly 214 includes a second rotating rod 301, a second transmission rod 303, and a third transmission rod 305. The second rotating rod 301 is fixedly connected above the first transmission rod 202. A first bevel gear 302 is fixedly connected to the outer side of the second rotating rod 301. The second transmission rod 303 is rotatably connected to the outer side of the outer casing 201. A second bevel gear 304 is fixedly connected to the outer side of the second transmission rod 303. The first bevel gear 302 meshes with the second bevel gear 304. The third transmission rod 305 passes through a set of baffles 211 and is fixedly connected to the outer side of the round rod 212. A transmission belt 306 is sleeved on the outside of the transmission rod 305. An opening 215 is provided on the outside of the outer shell 201 and on one side of the stacking platform 205. A groove 216 is provided above the moving platform 100 and below the opening 215. The stacking platform 205 is set as an inclined structure. The stacking platform 207 is set as an arc-shaped structure. The L-shaped pressing plate 208 is set as an arc-shaped structure on one side of the stacking platform 205. The slitting plate 213 is attached to the arc plate 210. The groove 216 is set as a trapezoidal structure.This application sets up a stacking platform 205 and a transmission assembly 214. When the motor 106 starts, it drives the round rod 212 to rotate via the transmission assembly 214. The rotation of the round rod 212 causes the six sets of slitting plates 213 to rotate around the round rod 212. Through the rotation of the six sets of slitting plates 213, the gravel and other debris that have accumulated behind the two sets of rotating plates 102 due to their rotation can fall onto the stacking platform 207 through the movement of the six sets of slitting plates 213. This is achieved by the reciprocating screw. The rotation of the first 204 allows the second 205 to move up and down along the reciprocating screw 204. When the second 205 moves downward and presses the L-shaped pressing plate 208, the first 207 gradually tilts towards one end of the second 205, causing the debris on the first 207 to fall onto the second 205. As the second 205 moves upward to the opening 215, the debris on the second 205 falls into the groove 216, thus achieving the purpose of collecting the debris.

[0028] In practical use, the above-mentioned equipment is configured such that a housing 201 is fixedly connected to the inner side of the moving platform 100, and a reciprocating screw 204 is rotatably connected to the inner side of the housing 201. A transmission rod 202 is fixedly connected above the reciprocating screw 204 and above the housing 201, so that the rotation of the transmission rod 202 drives the reciprocating screw 204 to rotate. A transmission belt 203 is sleeved on the outer side of the transmission rod 202 and the rotating rod 107, so that the rotation of the rotating rod 107 drives the transmission rod 202. A stacking platform 205 is rotatably connected to the outer side of the reciprocating screw 204, so that the rotation of the reciprocating screw 204 causes the stacking platform 205 to move back and forth up and down. A rotating rod 202 is rotatably connected to the inner side of the housing 201. 206, and a stacking platform 207 is fixedly connected to the outside of the rotating rod 206, so that the stacking platform 207 can rotate around the rotating rod 206. By fixing an L-shaped pressing plate 208 below the stacking platform 207, when the stacking platform 205 moves downward and presses the L-shaped pressing plate 208, the stacking platform 207 gradually tilts towards one end of the stacking platform 205, so that the debris on the stacking platform 207 falls onto the stacking platform 205. By fixing a spring 209 between the bottom of the stacking platform 207 and the outer shell 201, when the stacking platform 205 moves upward, the stacking platform 205 stops pressing the L-shaped pressing plate 208, so that the stacking platform 207 can be lifted by the spring 209. To maintain balance, an opening 215 is made on the outside of the outer shell 201 and on one side of the second stacking platform 205. A groove 216 is made above the moving platform 100 and below the opening 215. When the second stacking platform 205 moves upward to the opening 215, gravel and other debris above the second stacking platform 205 can fall into the groove 216 through the opening 215. An arc-shaped plate 210 is fixedly connected to the outside of the outer shell 201 and on one side of the first stacking platform 207. Baffles 211 are fixedly connected to both sides of the arc-shaped plate 210. A round rod 212 is rotatably connected between the two sets of baffles 211. Six sets of swashplates 213 are fixedly connected to the outside of the round rod 212. When the round rod 212 rotates, it drives the six sets of swashplates 213. The slitting plate 213 rotates, causing the gravel and other debris behind the two sets of rotating plates 102 to fall onto the material stacking platform 207 through the movement of the six sets of slitting plates 213. A rotating rod 301 is fixedly connected above the transmission rod 202, and a bevel gear 302 is fixedly connected to the outside of the rotating rod 301. When the transmission rod 202 rotates, it drives the rotating rod 301 and the bevel gear 302 to rotate together. A transmission rod 303 is rotatably connected to the outside of the housing 201, and a bevel gear 304 is fixedly connected to the outside of the transmission rod 303. The bevel gear 302 meshes with the bevel gear 304, so that when the bevel gear 302 rotates, it drives the bevel gear 304 and the transmission rod 303 to rotate together.By passing transmission rod 305 through a set of baffles 211 and fixing it to the outside of round rod 212, the rotation of transmission rod 305 drives the round rod 212 to rotate. By connecting transmission belt 306 to the outside of transmission rod 203 and transmission rod 305, the rotation of transmission rod 203 drives transmission rod 305 to rotate together via transmission belt 306.

[0029] Example 3, see Figures 6-7 In this embodiment, based on Embodiment 1, multiple sets of openings 401 are formed below the center of the groove 216 and on the outer side of the moving platform 100. A crusher 402 is installed below the moving platform 100 and below the openings 401. A motor 403 is installed above the moving platform 100. A reciprocating screw 404 is installed below the motor 403. A ring 405 is rotatably connected to the outer side of the reciprocating screw 404. A ring 406 is rotatably connected to the outer side of the ring 405. Six sets of rotating rods 407 are fixedly connected to the outside of the 06. A motor 408 is installed below the moving platform 100 and outside the reciprocating screw 404. A ring 409 is installed below the motor 408. A discharge port is provided below the crusher 402 and above the rotating rods 407. All six sets of rotating rods 407 are set as arc structures. The diameter of the ring 409 is the same as the diameter of the ring 3 406. Four sets of telescopic rods 410 are fixedly connected between the ring 409 and the ring 3 406. This application sets up two rings 405 and three rings 406. When motor 2 403 starts, it drives reciprocating screw 2 404 to rotate. The rotation of reciprocating screw 2 404 causes ring 2 405 to move up and down along reciprocating screw 2 404. The up and down movement of ring 2 405 causes ring 3 406 and four sets of telescopic rods 410 to move up and down together. By starting motor 3 408, motor 3 408 drives ring 409 to rotate, and at the same time drives the four sets of telescopic rods 410 and ring 3 406 to rotate together. This achieves the purpose of the four sets of telescopic rods 410 moving up and down while rotating around ring 3 406 as the center.
