[0001] This utility model relates to the field of tunnel construction equipment technology, specifically to a tunnel construction grouting trolley. Background Technology

[0002] In tunnel construction, grouting is a crucial step in ensuring the quality and durability of the tunnel structure. This is especially true for long tunnels, where the quality of grouting is paramount. However, current techniques for grouting long tunnels typically involve either erecting mobile scaffolding, having workers climb the scaffolding to manually insert grouting pipes into the grouting holes, or using a vehicle platform to lift workers and grouting pipes to the grouting hole location before workers insert the pipes. In practice, these methods are problematic because long tunnels require frequent relocation of the scaffolding, leading to low efficiency, high workload for workers, and difficulty in guaranteeing the effectiveness of the grouting. Utility Model Content

[0003] The purpose of this utility model is to provide a tunnel construction grouting trolley to solve the above problems, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The present invention provides a tunnel construction grouting trolley, including a trolley frame body. Both sides of the bottom of the trolley frame body are fixedly equipped with longitudinal bottom beams, and the bottom front and rear positions of the bottom of the longitudinal beams are combined with a traveling mechanism for driving the trolley frame body to move longitudinally.

[0006] The trolley frame body is fixedly equipped with multiple operating platforms on both sides and top, and ladders are installed between the multiple operating platforms to facilitate climbing to the operating platforms on each level.

[0007] Grouting components are assembled on both sides and top of the trolley frame body outside the operating platform, and part of the grouting components are located between the lower two sides of the trolley frame body to perform grouting operations on the grouting holes on the inner surface of the tunnel.

[0008] Preferably, the trolley frame body is a prefabricated steel frame with dimensions of 4m x 2.72m x 5.72m (length x width x height) and the bottom longitudinal beam is H300 x 300 with a total length of 4 meters.

[0009] Preferably, the operating platform is a steel platform, and the ladder is an inclined ladder equipped with guardrails.

[0010] Preferably, the walking mechanism includes a wheel frame and a walking drive device. The wheel frame is fixedly assembled at both the front and rear positions of the bottom longitudinal beam, and each wheel frame is rotatably mounted with a walking wheel arranged vertically in the longitudinal direction via a wheel axle. The walking drive device is also fixedly configured on the side of the bottom longitudinal beam, and the walking drive device is connected to the wheel axle on the corresponding side for driving the walking wheel to rotate.

[0011] Preferably, the outer surface of each of the walking wheels is covered with rubber tires, and the walking drive device is a motor drive device and is connected to the wheel axle on the corresponding side via chain drive.

[0012] Preferably, the top surface of the operating platform is equipped with a lifting platform with lifting and adjusting function.

[0013] Preferably, the lifting platform is an electric lifting platform or a hydraulic lifting platform.

[0014] Preferably, the grouting assembly includes an installation platform, a storage tank body, a grouting booster pump, and grouting pipelines. The installation platform is horizontally fixed between the lower two sides of the trolley frame body, and the storage tank body is fixedly installed on the top surface of the installation platform. The grouting booster pump is assembled and installed on both sides of the storage tank body on the installation platform, and the grouting booster pump is connected to the grout supply pipe on the corresponding side of the storage tank body. The grouting pipelines in an arched shape are provided on both sides and the top of the trolley frame body outside the operating platform, and telescopic grouting pipes that can output grouting liquid to the outside are evenly distributed and fixedly connected to the outside of the grouting pipelines. At the same time, the grouting pipelines are all connected to the corresponding grouting booster pumps through grout delivery pipelines.

[0015] Preferably, the grouting pipeline is provided in two sections, located at the front and rear positions of the trolley frame body respectively. The telescopic grouting pipelines are all equipped with length extension and retraction adjustment functions and are combined with electrically controlled valves for opening and closing.

[0016] Preferably, the volume of the liquid storage tank body is not less than 1500L and a liquid level observation window is embedded in the front. The water delivery rate of the grouting booster pump is 2.5 cubic meters per hour. A controller for frequency conversion adjustment of the power of the grouting booster pump and opening and closing control of the electronically controlled valve is installed in front of the liquid storage tank body.

[0017] The tunnel construction grouting trolley described above, in practical use, utilizes a grouting assembly assembled on the trolley frame. The grouting fluid is stored in a reservoir within this assembly, ensuring proper temporary storage. Simultaneously, the agitator mechanism stirs the grout within the reservoir, ensuring its uniformity and quality. Furthermore, after the telescopic grouting pipe is inserted into the grouting hole, the grouting fluid is pressurized and flowed through the delivery and grouting pipelines by a grouting booster pump, exiting from the telescopic grouting pipe to the grouting hole. This allows for grouting of the tunnel's inner surface grouting holes, improving the grouting effect. The telescopic grouting pipe's adjustable telescopic function ensures flexible connection to the grouting holes within the tunnel. Each telescopic grouting pipe is equipped with an electrically controlled valve, allowing for independent opening and closing control of each pipe. This allows for flexible adjustment of the opening and closing state of the telescopic grouting pipe according to actual needs during grouting operations, ensuring smooth completion of the grouting process. Furthermore, the presence of a traveling mechanism at the bottom of the trolley frame allows the trolley frame to move flexibly within the tunnel, changing its position. This movement facilitates the repositioning of the grouting components within the tunnel, enabling comprehensive grouting of all grouting holes within the tunnel. This reduces the workload of operators and improves grouting efficiency. Additionally, the lifting platform integrated into the top of the trolley frame's operating platform allows for both operator and equipment installation. The adjustable lifting platform accommodates different construction heights, enhancing the flexibility of the construction process.

[0018] The beneficial effects are as follows: 1. The trolley frame body assembly of this utility model is equipped with a grouting component. By storing the grouting liquid in the storage tank of the grouting component, the grouting liquid can be properly stored temporarily. At the same time, the grouting liquid in the storage tank can be stirred by the working mechanism of the agitator, so as to ensure the uniformity and quality of the grouting liquid. Moreover, after the telescopic grouting pipe is sent into the grouting hole, the grouting liquid is pressurized and flowed through the grouting pipeline and the grouting pipeline by the grouting booster pump and then output from the telescopic grouting pipe to the grouting hole. This can realize the grouting operation of the grouting hole on the inner surface of the tunnel and improve the grouting effect.

[0019] 2. The telescopic grouting pipe has a telescopic adjustment function, which ensures that the telescopic grouting pipe can be flexibly connected to the grouting holes in the tunnel. At the same time, each telescopic grouting pipe is equipped with an electric control valve, which allows for independent opening and closing control of each telescopic grouting pipe. This facilitates flexible adjustment of the opening and closing status of the telescopic grouting pipe according to actual needs during grouting operations, ensuring the smooth completion of the grouting operation.

[0020] 3. A traveling mechanism is provided at the bottom of the trolley frame body. By using the traveling drive device of the traveling mechanism to drive the traveling wheels to roll, the trolley frame body can move flexibly in the tunnel to change its position. This makes it easy to change the position of the grouting components in the tunnel by moving the trolley frame body. In turn, the grouting components can be moved to realize the overall grouting operation of grouting holes in various positions inside the tunnel, reducing the workload of operators and improving the efficiency of grouting operation.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] See Figures 1-2 As shown, this utility model provides a tunnel construction grouting trolley, including a trolley frame body 3. Both sides of the trolley frame body 3 are fixedly equipped with longitudinal bottom beams 301. The bottom of the longitudinal bottom beams 301 are combined with a traveling mechanism 4 at both the front and rear positions to drive the trolley frame body 3 to move longitudinally. Specifically, the traveling mechanism 4 includes wheel frames 401 and a traveling drive device 404. Wheel frames 401 are fixedly combined with the bottom of the longitudinal bottom beams 301 at both the front and rear positions, and each wheel frame 401 is rotatably mounted with a longitudinally vertically arranged traveling wheel 402 via a wheel axle 403. The sides of the longitudinal bottom beams 301 are also fixed with… The trolley frame 3 is equipped with a fixed walking drive device 404, which is connected to the corresponding axle 403 on the side for transmission. The walking drive device 404 drives the walking wheels 402 to rotate. This arrangement allows the trolley frame 3 to move flexibly within the tunnel, changing its position. This movement of the trolley frame 3 facilitates the repositioning of the grouting assembly 6 within the tunnel, enabling the overall grouting operation of grouting holes at various locations within the tunnel. Optionally, multiple operating platforms 1 are fixedly installed on both sides and the top of the trolley frame 3. Ladders 2 are connected between these multiple operating platforms 1, allowing operators to easily climb to each level. This arrangement allows personnel to easily inspect the actual condition of the tunnel walls by standing on the operating platforms 1.

[0029] See Figures 1-2As shown, grouting components 6 are assembled on both sides and top of the trolley frame body 3 outside the operating platform 1. Part of the grouting components 6 are located between the lower two sides of the trolley frame body 3, used to perform grouting operations on the grouting holes on the inner surface of the tunnel. Specifically, the grouting components 6 include an installation platform 6011, a storage tank body 607, a grouting booster pump 6010, and grouting pipelines 603. The installation platform 6011 is horizontally fixed between the lower two sides of the trolley frame body 3, and the storage tank body 607 is fixedly installed on the top surface of the installation platform 6011. Grouting booster pumps 6010 are assembled on both sides of the storage tank body 607 on the installation platform 6011, and the grouting booster pumps 6010 are respectively connected to the grout supply pipes 609 on the corresponding sides of the storage tank body 607. The grouting components 6 are located between the lower two sides and top of the trolley frame body 3 outside the operating platform 1. The location is equipped with an arched grouting pipe 603, and each grouting pipe 603 is uniformly and fixedly connected to a telescopic grouting pipe 602 that can output grouting fluid to the outside. At the same time, each grouting pipe 603 is connected to a corresponding grouting booster pump 6010 through a grout delivery pipe 604. The purpose of this arrangement is that, firstly, the grouting fluid is properly stored in the storage tank body 607 of the grouting component 6. Secondly, the grouting fluid in the storage tank body 607 is stirred by the working of the agitator mechanism 605 to ensure the uniformity and quality of the grouting fluid. Moreover, after the telescopic grouting pipe 602 is sent into the grouting hole, the grouting booster pump 6010 pressurizes the grouting fluid through the grout delivery pipe 604 and the grouting pipe 603 and outputs it from the telescopic grouting pipe 602 to the grouting hole, thus realizing the grouting operation of the grouting hole on the inner surface of the tunnel.

[0030] See Figures 1-2 As shown, the following optimizations have been made to this application. Specifically, the trolley frame body 3 is a prefabricated steel frame with dimensions of 4m x 2.72m x 5.72m (length x width x height). The bottom longitudinal beam 301 is H300 x 300 with a total length of 4 meters. This ensures that the design dimensions of the trolley frame body 3 meet the actual needs of tunnel grouting, and also ensures that the bottom longitudinal beam 301 has design dimensions that meet the usage requirements. Further optionally, the operating platform 1 is a steel platform, and the ladder 2 is an inclined ladder 2 equipped with guardrails, so that the configuration of both the operating platform 1 and the ladder 2 meets the usage requirements. Furthermore, the exterior of the traveling wheels 402 is covered with rubber tires, and the traveling drive device 404 is a motor-driven device that is connected to the corresponding axle 403 on the side via chain drive. This configuration firstly facilitates the traveling wheels 402 to have good lateral movement ability on the tunnel surface without the need for tracks, and secondly, it facilitates the traveling drive device 404 to drive the axle 403 and the traveling wheels 402 to roll together via chain drive.

[0031] See Figure 1 As shown, the top operating platform 1 is equipped with a lifting platform 5 with lifting and adjustment function. The reason for this arrangement is that the lifting platform 5 can be used for construction personnel operation and equipment installation. At the same time, the lifting and adjustment of the lifting platform 5 can meet the construction needs at different heights. Furthermore, the lifting platform 5 can be an electric lifting platform or a hydraulic lifting platform to ensure that the lifting platform 5 has a good and reliable performance.

[0032] See Figures 1-2 As shown, the grouting pipeline 603 is provided with two sections, located at the front and rear positions of the trolley frame body 3 respectively. The telescopic grouting pipes 602 all have length telescopic adjustment functions and are combined with an electrically controlled valve 601 for controlling opening and closing. This arrangement ensures that the design style and quantity of the grouting pipeline 603 can meet the overall grouting needs in the tunnel, while also ensuring that the telescopic grouting pipes 602 can flexibly connect to the grouting holes in the tunnel. Moreover, the opening and closing of each telescopic grouting pipe 602 can be independently controlled by the electrically controlled valve 601, thus facilitating the flexible adjustment of the opening and closing state of the telescopic grouting pipes 602 according to actual needs during grouting operations. Optionally, the volume of the storage tank body 607 is not less than 1500L and a liquid level observation window 608 is embedded in the front. The water delivery rate of the grouting booster pump 6010 is 2.5 cubic meters per hour. A controller 606 is installed in front of the storage tank body 607 to control the power of the grouting booster pump 6010 by frequency conversion and to control the opening and closing of the electrically controlled valves 601. The reason for this arrangement is that, firstly, the storage tank body 607 has a sufficient working volume, so that grouting liquid does not need to be frequently replenished. Secondly, the grout delivery rate of the grouting booster pump 6010 meets the usage requirements for grouting liquid injection. Moreover, it is convenient to use the controller 606 to control the power of the grouting booster pump 6010 by frequency conversion, so as to flexibly adjust the grouting rate according to actual usage needs. Furthermore, it is convenient to control the opening and closing of multiple electrically controlled valves 601 separately, so as to flexibly adjust the opening and closing state of the telescopic grouting pipe 602 according to actual usage needs during grouting operations.

[0033] With the above structure, in practical use, since the trolley frame body 3 is equipped with a grouting component 6, the grouting liquid can be properly stored by using the storage tank body 607 of the grouting component 6. At the same time, the grouting liquid in the storage tank body 607 can be stirred by the working of the agitator mechanism 605 to ensure the uniformity and quality of the grouting liquid. Moreover, after the telescopic grouting pipe 602 is sent into the grouting hole, the grouting booster pump 6010 uses the grouting pump to deliver the grouting liquid through the grouting pipe. The pressurized flow from grouting pipe 604 and grouting pipe 603, exiting through telescopic grouting pipe 602 to the grouting hole, enables grouting operations on the grouting holes on the inner surface of the tunnel, improving the grouting effect. Furthermore, the telescopic grouting pipe 602 has an adjustable telescopic function, ensuring flexible connection to the grouting holes within the tunnel. Each telescopic grouting pipe 602 is equipped with an electrically controlled valve 601, allowing for independent control of each pipe's opening and closing. The opening and closing control allows for flexible adjustment of the telescopic grouting pipe 602 according to actual needs during grouting operations, ensuring smooth completion of the grouting operation. Furthermore, the presence of a traveling mechanism 4 at the bottom of the trolley frame 3 allows the traveling wheels 402 to roll, enabling the trolley frame 3 to move flexibly within the tunnel and change its position. This movement facilitates the repositioning of the grouting component 6 within the tunnel, enabling comprehensive grouting of various grouting holes within the tunnel. This reduces the workload of operators and improves grouting efficiency. Additionally, the top surface of the operating platform 1 on the top of the trolley frame 3 is equipped with a lifting platform 5. This platform can be used for operator work and equipment installation, and its adjustable height meets different construction height requirements, enhancing the flexibility of construction.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
