Description

Technical Field

[0001] This utility model relates to the field of high-speed rail construction technology, specifically a device for breaking up the post-cast strip of a high-speed rail base. Background Technology

[0002] Chinese Utility Model Patent Application No. CN2025204036256 discloses a high-pressure breaking device for the post-cast strip of a high-speed railway base. The device includes a crossbeam with detachable track frames at both ends to drive its movement. A lifting assembly is detachably installed in the middle of the crossbeam, and a connecting plate is detachably installed at the output end of the lifting assembly. The connecting plate has an angle adjustment mechanism. This high-pressure breaking device for the post-cast strip of a high-speed railway base uses a single-sided spray pipe design. Since the post-cast strip is 3 meters long, when cleaning a 2-3 meter area of ​​the post-cast strip, the far end of the spray pipe is suspended, making spraying difficult. The high-pressure water flow experiences energy loss due to pipe vibration during long-distance transmission, resulting in a significant decrease in concrete breaking efficiency in that area.

[0003] Therefore, it is necessary to propose a device for breaking up the post-cast strip of high-speed rail base to solve the above problems. Utility Model Content

When cleaning the post-cast strip within a range of 2-3 meters, the spray pipe is suspended at the far end, making it difficult to spray at the far end. The high-pressure water flow loses energy due to the vibration of the pipe body during long-distance transmission, resulting in a significant decrease in the concrete breaking efficiency in this area.

The auxiliary removal mechanism comprises two U-shaped frames that are laterally spaced and clamped onto the protective wall, with a transverse moving mechanism between the two U-shaped frames. A lifting mechanism is fixedly installed on the moving end of the transverse moving mechanism. An installation box is fixedly installed on the moving end of the lifting mechanism, and a fixed... The system is equipped with a drive mechanism and a fixed block. The fixed block has a cavity along its longitudinal direction, and a high-pressure nozzle is rotatably mounted inside the cavity. A water inlet hole communicating with the cavity is opened on one side of the fixed block, and a water supply pipe is fixedly mounted inside the water inlet hole. The other end of the water supply pipe passes through the mounting box and is connected to the high-pressure water pump. A through hole communicating with the cavity of the fixed block is opened in the middle of the high-pressure nozzle. A nozzle head is fixedly installed at the end of the high-pressure nozzle near the high-speed rail track. The nozzle head has two spray holes arranged in a figure-eight shape. The other end of the high-pressure nozzle is connected to the drive mechanism for transmission.

[0006] Preferably, a screw I is threaded onto the U-shaped frame, with a rotating handle fixedly installed at one exposed end of the screw I, and an anti-slip seat rotatably installed at the other end of the screw I.

[0007] Preferably, the lateral movement mechanism includes a rack and two slide rails fixedly installed between two U-shaped frames. The rack and slide rails are both horizontally arranged, with the rack located between the two slide rails. The same fixed plate is fixedly installed on the side of the two slide rails closest to the high-speed rail track. Multiple pulleys are rotatably installed on the fixed plate, arranged in a rectangular array. Both slide rails are located within the enclosed area formed by the multiple pulleys and respectively abut against the pulleys on the adjacent side. A gear is rotatably installed on the fixed plate, meshing with the rack for transmission. A motor I and a worm gear reducer I are fixedly installed on the side of the fixed plate closest to the high-speed rail track, and the motor I is connected to the gear via the worm gear reducer I.

[0008] Preferably, the lifting mechanism includes an outer cylinder fixedly installed on the side of the fixed plate near the high-speed rail track. A worm gear reducer II and a motor III are fixedly installed on the outer cylinder. An inner cylinder is slidably fitted inside the outer cylinder along the vertical direction. A pin is rotatably installed at the upper end of the inner cylinder. A connecting ring is sleeved on the pin. A screw II is fixedly installed at the top of the connecting ring along the vertical direction. The worm of the worm gear reducer II is connected to the motor III for transmission. The worm wheel of the worm gear reducer II is threadedly fitted on the screw II.

[0009] Preferably, the drive mechanism includes a mounting plate fixedly installed inside the mounting box. A worm gear reducer III and a motor II are fixedly installed on the mounting plate. A rotating shaft is rotatably installed on the mounting plate. The motor II is connected to the rotating shaft via the worm gear reducer III.

[0011] Beneficial effects: Compared with the prior art, this utility model provides a high-speed rail base post-cast strip breaking device. This high-speed rail base post-cast strip breaking device has a unique structure and is easy to use. The main breaking mechanism first breaks the post-cast strip from the inside out. When the breaking depth reaches 2 meters, the auxiliary breaking mechanism is clamped to the protective wall by a U-shaped frame and driven by screw I to the anti-slip seat to abut against the protective wall to prevent the mechanism from sliding. At this time, the lateral movement mechanism of the auxiliary breaking mechanism is driven by motor I to drive the gear along the rack and pinion to adjust the horizontal position of the high-pressure nozzle. The lifting mechanism is driven by motor III to drive worm gear reducer II to adjust the height of the inner cylinder, so that the high-pressure nozzle is accurately aligned with the center position of the post-cast strip.

[0012] The water supply pipe introduces water from the high-pressure pump into the cavity of the fixed block, and then flows into the interior of the high-pressure nozzle through a through hole in the middle of the nozzle. Motor II drives the rotating shaft to rotate via a worm gear reducer III. The rotating shaft and the high-pressure nozzle are driven by a sprocket and chain, causing the nozzle to rotate synchronously. Because the two nozzles on the nozzle head are arranged in a figure-eight shape, the high-pressure water flow forms a conical impact head during rotation, and the coverage area expands with the rotation speed, achieving uniform crushing of the post-cast strip. This device uses a main crushing mechanism and an auxiliary crushing mechanism to operate from both ends of the post-cast strip, avoiding the efficiency reduction when a single mechanism operates at a remote end, and greatly improving the overall crushing efficiency.

[0024] A screw rod I 26 is threaded onto the U-shaped frame 21. A rotating handle is fixedly installed at the exposed end of the screw rod I 26, and an anti-slip seat 27 is rotatably installed at the other end of the screw rod I 26 via a bearing. The lateral movement mechanism includes a rack 23 and two slide rails 22 fixedly installed between the two U-shaped frames 21. The rack 23 and slide rails 22 are both horizontally arranged, with the rack 23 located between the two slide rails 22. The same fixing plate 24 is fixedly installed on the side of the two slide rails 22 closest to the high-speed rail track. The fixing plate 24 rotates via a bearing. Multiple pulleys 25 are installed in a rectangular array. Two slide rails 22 are located within the enclosed area formed by the multiple pulleys 25 and abut against the pulleys 25 on the adjacent side. A gear 226 is rotatably mounted on the fixed plate 24 via bearings. The gear 226 meshes with the rack 23 for transmission.

[0025] The lifting mechanism includes an outer cylinder 28 fixedly installed on the side of the fixed plate 24 near the high-speed rail track. A worm gear reducer II 211 and a motor III 229 are fixedly installed on the outer cylinder 28. An inner cylinder 212 is vertically slidably fitted inside the outer cylinder 28. A pin 213 is rotatably installed at the upper end of the inner cylinder 212. A connecting ring 214 is sleeved on the pin 213. A screw II 215 is fixedly installed vertically at the top of the connecting ring 214. The worm of the worm gear reducer II 211 is connected to the motor III 229 for transmission.

[0026] The drive mechanism includes a mounting plate 217 fixedly installed inside the mounting box 216. A worm gear reducer III 219 and a motor II 225 are fixedly installed on the mounting plate 217. A rotating shaft 218 is rotatably mounted on the mounting plate 217 via bearings. The motor II 225 is connected to the rotating shaft 218 via the worm gear reducer III 219.

The same chain is fitted on the two sprockets 222.

[0027] Working principle: When using this device, the main breaking mechanism 1 first breaks the post-cast strip from the inside out. After the main breaking mechanism 1 breaks the post-cast strip by two meters with high-pressure water flow, the auxiliary breaking mechanism 2 is clamped onto the protective wall. Then, the rotating handle on the screw I 26 is rotated, and the anti-slip seat 27 is tightly pressed against the protective wall through the threaded connection, thereby preventing the auxiliary breaking mechanism 2 from moving. After the auxiliary breaking mechanism 2 is fixed, the motor I 29 and motor III 229 are started in sequence, so that the high-pressure nozzle 221 is moved to the center position of the post-cast strip to be removed. Then, the water supply pipe 224 is connected to the high-pressure water pump. The high-pressure water flows into the cavity of the fixed block 220 through the water supply pipe 224 and into the high-pressure nozzle 221 through the through hole in the middle of the high-pressure nozzle 221.

[0028] The motor II225 is started. The motor II225 drives the rotating shaft 218 to rotate through the worm gear reducer III219, and then drives the high-pressure nozzle 221 to rotate through the chain drive. Since the two nozzles on the high-pressure nozzle 221 are arranged in a figure-eight shape, when the high-pressure nozzle 221 rotates, the high-pressure water flow will form a conical impact head, which facilitates the crushing of the post-cast strip. By using the main crushing mechanism 1 and the auxiliary crushing mechanism 2 to crush from both ends of the post-cast strip, the crushing efficiency of the post-cast strip is greatly improved.

[0029] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 2-7As shown, a connecting rod 227 is fixedly installed on the side of the mounting box 216 near the protective wall. A ball bearing 228 is embedded at the other end of the connecting rod 227. By setting the connecting rod 227 and the ball bearing 228, the mounting box 216 can be provided with support force to prevent the mounting box 216 from shaking under the action of the back force of the high-pressure water flow.
