Description
Technical Field
[0001] The present invention relates to the technical field of tunnel construction, and in particular to a multifunctional auxiliary trolley. Background Art
[0002] During the construction of conventional shield tunnels, when the shield machine is moving forward, the segments often have a large amount of splashing mud pollutants and a certain degree of mud leakage due to the unstable construction conditions. This phenomenon not only affects the efficiency of construction, but also may pose a potential threat to the safety of the subsequent tunnel structure. At the same time, the construction team faces many challenges during the assembly and post-finishing of the segments. For example, the joints between the segments may not be tight, resulting in the need for two groutings to ensure a firm connection. In addition, the damage to the surface of the segments during construction needs to be repaired to maintain the overall strength and stability of the tunnel. At the same time, the tightening of the bolts during the assembly process may also be unsatisfactory, resulting in the need for replacement and re-tightening, which not only increases the complexity of the construction, but may also delay the overall construction period. In addition, the secondary cleaning of the pipe wall is also an important link that cannot be ignored, aimed at removing residual mud and pollutants to ensure the smooth progress of subsequent construction and the long-term stability of the tunnel. The post-finishing work of the tunnel, such as painting and waterproofing, also needs to be carried out after the cleaning and repair work is completed.

[0023] The embodiment of the present invention discloses a multifunctional auxiliary trolley for assisting tunnel construction, comprising: a trolley body 100, the trolley body 100 comprising a moving device 110, the moving device 110 is arranged on the trolley body 100, and the moving device 110 can drive the trolley body 100 to move along the tunnel; a cleaning device 200, the cleaning device 200 comprises a support frame 210 and a cleaning component 220, the support frame 210 is fixedly arranged on the trolley body 100, the cleaning component 220 is arranged on the outer peripheral surface of the support frame 210 according to a preset interval, and the cleaning component 220 is used to clean the pipe wall in the tunnel; a recovery device 300, the recovery device 300 is arranged on the trolley body 100, and the recovery device 300 is used to recover the sewage used by the cleaning component 220 to clean the pipe wall.
[0024] By adopting the mobile device 110, the trolley can be flexibly moved in the tunnel, which greatly improves the maneuverability of the construction. Compared with the traditional manual cleaning method, the mobility of the trolley can enable the cleaning operation to cover a larger range, reduce the need for manual operation, and thus improve work efficiency. At the same time, the design of the trolley can be adjusted according to the specific environment of the tunnel, adapt to tunnels of different diameters and shapes, and ensure the continuity and stability of the construction. The setting of the cleaning device 200 makes the pipe wall cleaning work systematic and automated. Through the cleaning assembly 220 on the support frame 210, the trolley can pump the water pump 320 to effectively clean the pipe wall in the tunnel within the prescribed interval, ensuring the uniformity and thoroughness of the cleaning. The timely recovery of sewage can not only avoid pollution to the construction environment, but also realize the reuse of cleaning water resources, which meets the current environmental protection requirements. Through the centralized treatment of sewage, the environmental sanitation of the construction site has been improved, thereby ensuring the health and safety of the construction workers.
[0025] In some embodiments, the structure of the support frame 210 is arc-shaped, and the number of cleaning components 220 is four, and the four cleaning components 220 are respectively arranged on the outer peripheral surface of the support frame 210 according to preset spacing. The arc-shaped support frame 210 can better fit the inner wall of the pipe wall, maximize the contact area between the cleaning component 220 and the pipe wall, not only enhance the cleaning effect, but also effectively avoid blind spots in the cleaning process, thereby ensuring that every pipe wall is fully cleaned. The four cleaning components 220 are distributed according to the preset spacing, which can achieve uniform cleaning coverage, ensuring that when the trolley moves, the cleaning components 220 can work efficiently at the same time, reduce cleaning time, and improve overall operating efficiency.
[0026] In some embodiments, the cleaning assembly 220 includes a cleaning tank 221 and a telescopic member 222. The cleaning tank 221 is arranged at the telescopic end of the telescopic member 222. The cleaning tank 221 is symmetrically provided with sealing strips 223 on both sides. A brush head 224 is provided on the inner circumference of the cleaning tank 221. The telescopic member 222 drives the cleaning tank 221 and drives the brush head 224 to move back and forth. The telescopic member 222 can adjust the distance of the cleaning tank 221 according to the actual width of the tunnel to ensure that it is in close contact with the pipe wall for effective cleaning, so that the cleaning can adapt to tunnels of different diameters, and enhance the versatility of the equipment. The design of the sealing strips 223 on both sides of the cleaning tank 221 prevents the leakage of cleaning agents and sewage. The sealing strips 223 can fit closely to the pipe wall to form a good sealing effect, ensure that the cleaning liquid can act on the dirt surface, improve the cleaning effect, and reduce the waste of resources caused by liquid overflow. The setting of the brush head 224 on the inner circumference makes the cleaning process more efficient. The reciprocating movement of the brush head 224 can achieve mechanical cleaning of the pipe wall, and with the use of cleaning liquid, stubborn dirt can be effectively removed. Driven by the telescopic member 222, the brush head 224 can quickly and evenly cover the cleaning area to ensure that there is no dead corner.
[0027] In some embodiments, the cleaning tank 221 is further provided with water outlet holes 225, which are evenly arranged at the bottom of the inner circumference of the cleaning tank 221. The cleaning tank 221 is also provided with drain pipes 226 on both sides perpendicular to the sealing strip 223, and the drain pipes 226 are connected to the recovery device 300. The uniform arrangement of the water outlet holes 225 can ensure the effective distribution of the cleaning liquid in the cleaning tank 221. When the cleaning tank 221 is working, the cleaning liquid can be evenly sprayed through these water outlet holes 225 to form a spray or flow state, which can better penetrate into every corner of the pipe wall and improve the cleaning effect. The water outlet holes 225 at the bottom of the cleaning tank 221 are combined with the design of the drain pipe 226, and the sewage and residues generated during the cleaning process can be quickly discharged through the drain pipe 226 and sent to the recovery device 300, avoiding the retention of sewage in the cleaning tank 221. The over-cleaned sewage can be collected and processed, and part of the cleaning liquid can be recycled, thereby achieving a more environmentally friendly cleaning process.
[0028] In this embodiment, the working principle of the cleaning device 200 is as follows: after the multifunctional trolley is installed, the telescopic member 222 pushes the cleaning assembly 220, and when the brush head 224 fits the inner wall of the pipe, after moving 3-5mm, the sealing strips around the cleaning tank 221 fit tightly with the inner wall of the pipe. When the shield advances forward, the translation device of the cleaning tank 221 starts to work. The cleaning tank 221 translates 300mm to perform two reciprocating movements. The first time, a single row of water outlet holes 225 and a single row of 80 water outlet holes 225 work, and the 300mm translation speed is 80mm / s. When the 300mm stroke is completed, the water outlet holes 225 stop spraying water, and the brush head 224 cleans the tank 221, and performs two reciprocating movements at a speed of 40mm / s. When the scraping stroke is completed, 160 water outlet holes 225 are opened at the same time, and the movement speed of the cleaning tank 221 is 30mm / s. A 300mm degree action is completed. The cleaning action enters the next repeated cycle process. After the lifting operation of the inner wall of the pipeline is completed, the materials required by the cleaning device 200 are replenished. After being separated from the shield machine, the battery pallet truck is connected to move to the rear side of the excavation direction, and the above movement is repeated. 80 of the last 160 water nozzles can be opened to achieve the minimum total working power consumption. The high-pressure water jet angle is 65°, the water outlet hole 225 has a diameter of 1.8, the flow rate is L / min, the pressure bar is: 5.8L / 10bar, and the motor power is 28KW.
[0029] In some embodiments, the cleaning device 200 further includes a clean water tank 230, which is movably arranged on the trolley body 100, and the clean water tank 230 is connected to the cleaning device 200. The clean water tank 230 is arranged in the cleaning device 200 and is movably connected to the trolley body 100. The clean water tank 230 enables continuous water supply during the cleaning process to ensure sufficient and stable cleaning liquid. The continuous water supply mechanism reduces the need for frequent water replenishment during the cleaning process and improves work efficiency, which is particularly important in large-scale cleaning operations. The movable setting of the clean water tank 230 greatly enhances the flexibility of the equipment. The operator can adjust the position of the clean water tank 230 according to the specific conditions of the site to adapt to different cleaning needs. The connection design between the clean water tank 230 and the cleaning device 200 optimizes the water flow path and reduces the loss and delay in the water source transportation process. It ensures that the cleaning liquid can reach the cleaning area quickly and effectively, thereby improving the cleaning effect. At the same time, the clean water tank 230 can be used as a pre-treatment device for the cleaning liquid, so that the water quality is controlled, thereby improving the cleaning quality.
[0030] In some embodiments, the cleaning device 200 further includes a sewage tank 310, which is movably arranged on the trolley body 100, and the sewage tank 310 is connected to the drain pipe 226. The sewage tank 310 is arranged in the cleaning device 200 and movably connected to the trolley body 100. The sewage tank 310 realizes the centralized collection and treatment of sewage, avoids the random discharge of sewage during the cleaning process, not only improves the cleanliness of the cleaning work, but also effectively reduces the pollution to the environment, and meets the modern environmental protection requirements. The movable setting of the sewage tank 310 enhances the flexibility of the equipment. The operator can adjust the position of the sewage tank 310 according to the on-site requirements to adapt to different cleaning environments. The connection between the sewage tank 310 and the drain pipe 226 ensures that the sewage can be discharged quickly and efficiently, reduces the retention time of sewage during the cleaning process, and reduces the risk of corrosion and blockage caused by the accumulation of sewage, thereby extending the service life of the equipment.
[0031] In some embodiments, the multifunctional auxiliary trolley further includes a double-layer slurry agitator, which is movably arranged on the trolley body 100. The double-layer slurry agitator has two layers of 300 liters each, a motor power of 3Kw, and a slurry discharge hole size of 3". Double-liquid grouting pump, motor power of 7.5W, suction pipe diameter of 32mm, slurry discharge pipe diameter of 19mm, pump action form: horizontal double cylinder and piston, fast gear: rated displacement L / min: 70, rated pressure Mpa: 2, reciprocating times: times / min: 72, slow gear: rated displacement L / min: 42, rated pressure Mpa: 4, reciprocating times, times / min: 43. The double-layer stirring structure can effectively improve the uniformity and stability of the slurry. During the cleaning and construction process, the composition and concentration of the slurry remain consistent to ensure the best cleaning effect and construction quality. The double-layer agitator 400 can fully mix the various components in the slurry through alternating stirring of the upper and lower layers, avoiding sedimentation and stratification, and ensuring the high efficiency of the slurry when in use. The double-layer slurry agitator can also improve work efficiency. Compared with the single-layer agitator, the double-layer design can achieve the ideal stirring effect in a shorter time, reducing the time for slurry preparation. This efficient stirring mechanism can quickly respond to the needs of the site and improve the overall construction efficiency. The double-layer agitator 400 also helps to reduce maintenance costs. As the uniformity and stability of the slurry are improved, the service life and reliability of the equipment are also enhanced, reducing equipment failures and maintenance requirements caused by uneven slurry.
[0032] In some embodiments, the multifunctional auxiliary trolley further includes a working platform, which is arranged on the trolley body 100, and the working platform includes a first platform 510, a second platform 520 and a third platform 530. The design of multiple platforms enhances the flexibility and adaptability of the operation. According to the requirements of the specific task, the operator can flexibly adjust the use of each platform and quickly respond to different work requirements. The multi-layer structure of the working platform contributes to the rational use of space. Different platforms can perform different operations at the same time, avoiding the crowding of equipment and tools and improving the neatness of the work site.
[0033] In some embodiments, the multifunctional auxiliary trolley further includes a material storage platform 600, which is arranged on the trolley body 100. In some embodiments, the multifunctional auxiliary trolley further includes a lifting device 700, which is movably arranged above the trolley body 100. The material storage platform 600 provides a space for centrally storing various tools and materials, making on-site work more orderly. Operators can easily obtain the required materials, reduce the time of searching and carrying, and improve work efficiency. The lifting device 700 greatly improves the versatility of the trolley. The movable lifting device 700 can easily lift heavy objects, facilitate operation at different heights, and meet various construction needs. The combination of the material storage platform 600 and the lifting device 700 can realize efficient handling and use of materials. The materials on the storage platform can be directly lifted to the required position by the lifting device 700, reducing the time and manpower required for traditional handling methods and improving the overall fluency of the operation.
[0034] In some embodiments, the various functions of the multifunctional trolley are all modularly designed, and the functions can be expanded according to specific needs. When excavating forward with the shield, it can automatically clean the pipe wall, perform secondary grouting, and meet the location requirements of various operation constructions, and the trolley has strong functional expandability. When encountering an emergency and after the shield excavation is completed, it can be separated from the shield machine and combined with the battery trolley. An emergency work platform is formed to handle emergencies, and the overall cleaning, detection, and secondary grouting of the pipe wall in the later stage are convenient. The automatic cleaning capacity of the pipe wall is greatly improved, and various expansion functions also improve construction efficiency.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents.
