Description

TECHNICAL FIELD

[0001] The utility model relates to road repair technical field, concretely is frozen soil area road prevention and control subsidence disease device. BACKGROUND

[0002] When building roads in frozen soil areas, the stability of the frozen soil is extremely susceptible to temperature changes because of its special engineering properties. When the external temperature rises, the ice in the frozen soil melts, the soil structure is destroyed, the bearing capacity of the foundation is reduced, and then the road subsidence, deformation and other diseases are caused. When the temperature decreases, the frozen soil will also have frost heaving phenomenon, which will also have adverse effects on the road structure.

[0003] The subsidence, frost heaving and other diseases not only reduce the service life of the road, affect the driving safety and comfort, but also greatly increase the maintenance cost of the road. At present, for the prevention and control of frozen soil area road subsidence disease, methods such as replacement, laying of thermal insulation layer, setting of drainage system are usually used, but these methods often have problems such as complex construction, high cost, limited prevention and control effect or short duration. The hose lacks a stable positioning mechanism and is prone to displacement, shaking or even falling under the action of material conveying pressure. Because the working environment in the frozen soil area is complex, the ground may have frost heaving or unevenness. If the hose cannot be accurately fixed, the material spraying position will be offset, it is difficult to uniformly cover the target area, and the filling and paving quality and the prevention and control effect will be affected. The hose may also be entangled or collided with the surrounding equipment due to random shaking, increasing the operation safety hazard. At the same time, the connection between the hose and the feeding system usually adopts a fixed or simple buckle structure, and the disassembly process is complicated. When different specifications of hoses need to be replaced to adapt to different filling and paving ranges, or the hose needs to be cleaned and repaired, multiple step operations often need to be performed with the aid of tools. Not only is the equipment adjustment time prolonged, the work efficiency is reduced, but also the connection components may be worn due to frequent disassembly, affecting the sealing performance and causing material leakage and waste.

[0035] Furthermore, such as Figure 6 As shown, the limiting assembly includes a limiting seat 25 fixedly installed on the top of the base 1.

A control rod 210 is provided on one side of the limiting seat 25. Two linkage rods 213 are fixedly installed on one side of the limiting plate 29.

[0036] For further reference Figure 1 and Figure 7 The disassembly and assembly mechanism 3 includes a threaded seat 34 fixedly installed on one side of the transfer box 9 and a sealing strip 36 fixedly installed on one end of the hose 4. The sealing strip 36 cooperates with the transfer box 9. A rotating sleeve 31 is fixedly installed on the outer wall of the hose 4. A threaded sleeve 32 is rotatably installed on the outer wall of the rotating sleeve 31. A positioning sleeve 33 is fixedly installed on one side of the threaded sleeve 32.

A contact groove 35 matching the rotating sleeve 31 is opened on one side of the threaded seat 34.

[0037] The overall working principle of this utility model is as follows:

[0038] First, the material for preventing subsidence is added to the storage bin 6 through the feed hopper 7. The drive motor 10 is then started, and its output drives the transmission shaft 12 to rotate. Multiple sets of stirring rods 11 on the outer wall of the transmission shaft 12 rotate accordingly, stirring the material in the storage bin 6 to prevent clumping and ensure uniformity. The material inside the storage bin 6 is then transported to the transfer box 9 by the pump 8, and finally sprayed out through the hose 4 and nozzle 5. When it is necessary to disassemble or reassemble the hose 4, the sealing strip 36 at one end of the hose 4 is connected to the transfer box. 9. Insert the threaded sleeve 32, then rotate the threaded sleeve 32. Since the threaded sleeve 32 is threadedly connected to the threaded seat 34, as the threaded sleeve 32 rotates, the positioning sleeve 33 rotates in the rotating groove of the rotating sleeve 31. At the same time, the threaded sleeve 32 continuously moves closer to the threaded seat 34, eventually causing the rotating sleeve 31 to abut against the contact groove 35 of the threaded seat 34, completing the connection between the hose 4 and the transfer box 9. This ensures that the material can smoothly enter the hose 4 from the transfer box 9. Subsequently, the positioning mechanism 2 positions the hose 4, placing it at the bottom of the positioning seat 21. The positioning seat 21 is fixed to the top of the base 1 by bolts 22 that are screwed between multiple fixing plates 23 and the base 1 in a circular groove that matches the hose 4. The clamping plate 24 is rotated so that it rotates around the rotation axis 27 and contacts the hose 4. Then, the clamping plate 24 is limited by the limiting assembly. In the limiting assembly, the elastic force of the compression spring 211 pushes the limiting plate 29 so that the limiting plate 29 cooperates with one side of the clamping plate 24, limiting the rotation of the clamping plate 24, thereby stably clamping the hose 4 between the clamping plate 24 and the support seat 26. If it is necessary to release the clamp, the linkage rod 213 can be driven by the control rod 210 to compress the limit plate 29 and squeeze the spring 211 away from the clamp plate 24, so that the clamp plate 24 can be rotated. Through the cooperation of the limit plate 29 and the squeeze spring 211, the position of the clamp plate 24 can be stably restricted, ensuring that the hose 4 remains reliably fixed in complex environments such as low temperature, avoiding positioning failure caused by component stiffness; at the same time, it reduces the risk of equipment entanglement and collision caused by the shaking of the hose 4, and ensures the operational safety in the frozen soil environment.
