Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a pressurized concrete pumping pipeline and cleaning device for a tunnel secondary lining trolley. Background Technology

[0002] During tunnel construction, the secondary lining trolley is a key piece of equipment, and its efficiency and quality in concrete delivery and pouring directly affect the overall progress and quality of the tunnel project. However, existing secondary lining trolleys often suffer from uneven delivery, easy pipe blockage, and difficulty in cleaning during concrete delivery. These problems not only reduce construction efficiency but may also affect the quality of the concrete, thereby impacting the stability and durability of the tunnel structure.

[0003] Therefore, it is particularly important to develop an efficient and reliable concrete pressurized pumping pipeline and cleaning device. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of uneven delivery, easy blockage of pipelines and difficulty in cleaning that often exist in the concrete delivery process of the secondary lining trolley in the prior art. These problems not only reduce construction efficiency, but may also affect the quality of concrete, and thus affect the stability and durability of the tunnel structure. Therefore, a pressurized concrete pumping pipeline and cleaning device for tunnel secondary lining trolley is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pressurized concrete pumping pipeline and cleaning device for tunnel secondary lining trolley includes a trolley body, a bracket fixedly installed at the top center of the trolley body, a template fixedly installed on the outer wall of the trolley body, multiple moving wheels fixedly connected to both sides of the bottom of the trolley body, multiple material inlet windows opened on the outer wall of the template, and conveying components for conveying materials fixedly connected to both sides of the bracket for conveying materials to the side of the template.

[0007] A rotating punching port body is fixedly connected to the bracket, and the rotating punching port body is used to convey materials to the top of the template;

[0008] A cleaning assembly is also fixedly installed on the bracket, which is used to clean the pipe.

[0009] In one possible design, the conveying assembly includes two main chutes fixedly connected to both sides of the support. One end of each main chute is fixedly connected to a third inlet chute, which corresponds to the upper inlet window. A diversion chute is fixedly connected to the lower end of one end of the main chutes. One end of the diversion chute is fixedly connected to a vertical distribution cylinder. A second inlet chute is fixedly connected to the top side of the vertical distribution cylinder, which is connected to the middle inlet window. A first inlet chute is fixedly connected to the bottom of the vertical distribution cylinder, which is connected to the bottom inlet window.

[0010] In one possible design, the main body of the rotating punching port includes rotating punching port four, rotating punching port three, rotating punching port two, and rotating punching port one. Rotating punching ports four, three, two, and one are all located at the top of the template and arranged sequentially, connected by pipes. A symmetrical material distribution tee four, three, two, and one are also fixedly connected to one side of the support. The symmetrical material distribution tee is staggered with the rotating punch port 4, rotating punch port 3, rotating punch port 2 and rotating punch port 1 respectively. The two ends of the symmetrical material distribution tee 4, symmetrical material distribution tee 3, symmetrical material distribution tee 2 and symmetrical material distribution tee 1 are respectively connected to the main chute on both sides. One end of the symmetrical material distribution tee 4, symmetrical material distribution tee 3, symmetrical material distribution tee 2 and symmetrical material distribution tee 1 is connected to the pipe between the rotating punch port 4, rotating punch port 3, rotating punch port 2 and rotating punch port 1 and is used to supply material to it.

[0011] In one possible design, the cleaning assembly includes a cleaning pipe with a cleaning connector fixedly connected to one end. The cleaning connector is connected to a rotating punch port, and the cleaning pipe is used to deliver high-pressure air into the pipe.

[0012] In one possible design, a material cart is fixedly connected to one side of the trolley body, the material cart's discharge pipe is fixedly connected to a main feed pipeline, one end of the main feed pipeline is fixedly connected to a concrete feed pump pipe, and one end of the concrete feed pump pipe is fixedly connected to a rotary converter.

[0013] In one possible design, rotary converter one is fixedly connected to rotary converter three and rotary converter two at its two ends respectively, rotary punch three and rotary punch two are fixedly connected to the same rotary converter four, rotary converter four is connected to rotary converter two, and rotary converter three is connected to symmetrical material distribution tee three through a pipe.

[0014] In this application, the main design concept of the pouring system is to combine rotating pipeline switching with concrete pipeline chutes.

[0015] This design eliminates the rotary casting and trolley casting systems, significantly reducing operating costs.

[0016] Compared to trolley-based or rotary casting, this method is easier to operate and requires less space for piping. The elimination of the moving mechanism significantly improves the safety of operating the equipment on the trolley.

[0017] This device fully considers the symmetrical material distribution system of the side mold, improves the pouring efficiency, and the top sealing uses a rotating device to form a fan-shaped seamless seal, improving the appearance quality of the concrete.

[0018] The equipment is equipped with 4 sets of symmetrical material distribution tees, 4 sets of rotary converters, 4 sets of top rotary punching ports, and 1 set of matching feeding chute.

[0019] The specific implementation method for side formwork material feeding is shown in the attached diagram: If concrete has just been poured for the secondary lining trolley, the plan is to pour concrete into feed window 1-1. Control rotary converter one to connect the pipeline to rotary converter two. Control rotary converter two to connect to symmetrical distribution tee one. Concrete is connected to the main chute through symmetrical distribution tee one. The main chute is connected to the diversion chute, which is then connected to the vertical distribution cylinder, which is connected to feed chute one. The concrete reaches the designated feed window 1-1. In the same way, concrete can reach other side formwork windows.

[0020] The specific implementation method for the top impeller is as follows: As shown in the attached diagram, the plan is to feed material into rotary impeller one. Control rotary converter one to connect the pipeline to rotary converter two. Rotary converter two is connected to rotary converter four. Rotary converter four is connected to rotary impeller two, and rotary impeller two is connected to rotary impeller one. Pressurized concrete is poured into rotary impeller one. Concrete can be delivered to any other top impeller in the same manner.

[0021] Regarding the cleaning of pipelines:

[0022] High-pressure air (from an external air compressor and storage tank) is introduced from the rightmost pigging ball and cleaning connector on the diagram. It is equipped with a switch ball valve for controlling the supply of air.

[0023] Once the concrete has been poured into inlet window 1-1, the concrete pipeline has switched to inlet window 1-2, the cyan path. At this point, rotary converters four and two can be controlled to form a purple cleaning loop. Cleaning can be performed on any pipeline by using time differences and controlling each rotary switch.

[0024] Beneficial effect: The system allows for window-by-window injection of the mold.

[0025] It replaces the traditional rotary casting system (accessory), which has complex piping.

[0026] It also replaced the complex mechanical structure of the trolley (attached).

[0027] Beneficial effect: The system allows for window-by-window injection of the mold.

[0028] It replaces the traditional rotary casting system (accessory), which has complex piping.

[0029] It also replaced the trolley casting of complex mechanical structures (attached);

[0030] High-efficiency conveying: Through the coordinated work of the conveying components and the rotating top-pumping body, the concrete material is uniformly conveyed from both sides of the trolley body to the side of the formwork, and efficiently pushed from the top of the formwork, which significantly improves the concrete conveying efficiency.

[0031] Flexible adjustment: The staggered arrangement of the rotating punching port and the symmetrical material distribution tee allows the material conveying path to be flexibly adjusted according to actual construction needs, ensuring the uniformity and quality of concrete pouring.

[0032] Easy to clean: The design of the cleaning components allows the inside of the pipes to be quickly cleaned after each construction, effectively preventing pipe blockage and extending the service life of the equipment.

[0033] Compact structure: The overall structure is compact, easy to install and disassemble, and facilitates rapid deployment and movement during tunnel construction. Attached Figure Description
