Description

Technical Field

[0001] This utility model belongs to the technical field of tunnel engineering equipment, specifically relating to a transfer and storage device and a shotcrete trolley. Background Technology

[0002] In existing technology, before a shotcrete trolley can perform shotcrete operations, the anchor bolts must first be installed. After the anchor bolts are installed, the cement mixer truck driver drives the mixer to the rear of the trolley to supply cement slurry to the trolley's pumping system, and then operates the shotcrete arm to perform shotcrete operations on the working face. However, each shotcrete operation requires the cement mixer truck to enter the site to supply cement slurry to the pumping system, which cannot guarantee that the hopper will have sufficient slurry reserves for a long period of time. Furthermore, during shotcrete operations, the driver must remain on the mixer truck to wait for the shotcrete work to be completed before leaving the site, resulting in long waiting times and low efficiency. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a transfer and storage device and a shotcrete trolley to solve the problem that the existing shotcrete trolleys need to rely on external cement mixer trucks to enter the site multiple times to provide cement slurry, resulting in low shotcrete efficiency.

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

[0005] On one hand, a transfer and storage device is provided, including a support frame, a storage component, and an anti-condensation mechanism. The support frame is provided with a trough-shaped storage component, the inner cavity of which is a storage chamber. The storage chamber is provided with a slurry anti-condensation mechanism. The opening of the trough-shaped storage component is at least partially formed as a receiving port, which faces upward to connect with a feeding device. The trough-shaped storage component is provided with a discharge port for connecting to a pumping system of a shotcrete trolley.

[0006] In one possible implementation, the trough-shaped storage component is provided with a mesh assembly, the mesh assembly including a screen covering the receiving port.

[0007] In one possible implementation, the mesh assembly also includes a protective mesh arranged alongside the screen to jointly cover the opening of the trough-shaped storage component.

[0008] In possible implementations, the trough-shaped storage component is provided with flushing pipes distributed circumferentially along the opening; and / or, the protective net is separable from the trough-shaped storage component.

[0009] In a possible implementation, an attitude adjustment component is also included, wherein the trough-shaped material storage component is movably mounted on the support frame, and the attitude adjustment component drives the trough-shaped material storage component to adjust its pitch angle in the direction toward the discharge port.

[0010] In one possible implementation, one end of a trough-shaped storage component with a discharge port is rotatably connected to a support frame, and the other end of the trough-shaped storage component is connected to the support frame through the attitude adjustment component. The attitude adjustment component drives the trough-shaped storage component to switch between an inclined position and a horizontal position.

[0011] In a possible implementation, the rotatable end of the trough-shaped storage component is provided with a first support leg, which is raised or lowered as the trough-shaped storage component moves.

[0012] And / or, the support frame is provided with a plurality of second support legs.

[0013] In one possible implementation, the outer side of the trough-shaped storage component is provided with a reinforcing frame, which includes a main body covering the outer surface of the trough-shaped storage component and a plurality of support beams spanning over the opening of the trough-shaped storage component.

[0014] In one possible implementation, the support frame includes a main frame with a disassembly port and a mounting beam detachably connected to the disassembly port. When the mounting beam is separated from the main frame, the trough-shaped storage component can be inserted into the main frame through the disassembly port.

[0015] On the other hand, a shotcrete trolley is also provided, including a frame and a transfer storage device as described in any of the above claims, wherein the outlet of the trough-shaped storage component is connected to the pumping system of the shotcrete trolley.

[0016] The carrier frame of the transfer storage device is fixedly connected to one side of the vehicle frame to move synchronously, or the transfer storage device does not move synchronously with the shotcrete trolley and the discharge port of the trough-shaped storage component is connected to the pumping system of the shotcrete trolley through an extension pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The transfer and storage device and shotcrete trolley of this utility model have functions such as storing cement slurry, automatic anti-coagulation, and material discharge. The trough-shaped storage component can store a larger amount of cement slurry. The trough-shaped storage component can be easily connected with cement tank trucks and other material supply equipment through the material inlet. The large amount of cement slurry stored inside can provide a continuous and large amount of cement slurry for the shotcrete trolley. This ensures that the trolley has more slurry for continuous shotcreting in single shotcreting operations and multiple continuous shotcreting operations, improves work efficiency, avoids long-term occupation of cement slurry mixing trucks, saves construction time, and provides a guarantee for cyclical and continuous construction.

[0019] Moreover, the transfer and storage device can be fixedly connected to the shotcrete trolley, allowing the storage device to move synchronously with the shotcrete trolley.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] Please refer to Figure 1-6 As shown, an embodiment of this application provides a transfer and storage device 1, including a support frame 11, a storage component and an anti-condensation mechanism. The support frame 11 is provided with a trough-shaped storage component 12, the inner cavity of the trough-shaped storage component 12 is a storage chamber 121, the storage chamber 121 is provided with a slurry anti-condensation mechanism, the opening of the trough-shaped storage component 12 is at least partially formed as a receiving port, the receiving port faces upward to connect with a feeding device, and the trough-shaped storage component 12 is provided with a discharge port for connecting to the pumping system of the shotcrete trolley 2.

[0029] The intermediate storage device 1 is used for the intermediate storage of cement slurry. It can provide storage for feeding equipment such as cement mixer trucks without occupying the feeding equipment. It can also provide a more stable and continuous slurry supply to the wet spraying trolley by storing a large amount of cement slurry, thereby avoiding the occupation of the feeding equipment, improving work efficiency, and saving costs. The trough-shaped storage component 12 has a trough structure, which can be square or U-shaped. It can store a large amount of cement slurry, and its open top opening can be used as a receiving port for feeding equipment such as cement mixer trucks, making receiving more convenient and faster. The discharge port of the trough-shaped storage component 12 is used to connect to the pumping system of the spraying trolley 2 to provide slurry for pumping. In specific implementation, the intermediate storage device 1 can provide slurry at a fixed point or move synchronously with the spraying trolley 2 to provide slurry. In specific implementation, the trough-shaped discharge component is U-shaped, which has better structural integrity and can obtain a longer length in the axial direction, reducing the occupation of lateral space.

[0030] Through the above technical solution, the transfer and storage device 1 has functions such as storing cement slurry, automatic anti-coagulation, and material discharge. The trough-shaped storage component 12 can store a larger amount of cement slurry. The trough-shaped storage component 12 can be easily connected with cement tank trucks and other material supply equipment through the material inlet. The large amount of cement slurry stored inside can provide a continuous and large amount of cement slurry for the shotcrete trolley 2. This ensures that the trolley has more slurry for continuous shotcrete operation in single shotcrete operation and multiple continuous shotcrete operations, improves operation efficiency, avoids long-term occupation of cement slurry mixer truck, saves construction time, and provides a guarantee for cyclical and continuous construction.

[0031] In one embodiment, combined with Figure 2 As shown, the trough-shaped storage component 12 is provided with a mesh assembly, which includes a screen 13 covering the material receiving port.

[0032] In this way, the mesh assembly can act as a filter or interceptor, providing better protection for the trough-shaped storage component 12 with a large opening, and the screen 13 can prevent large objects from entering the trough-shaped storage component. In specific implementation, the screen 13 is also equipped with a vibration motor 20 to improve feeding efficiency and prevent clogging.

[0033] Furthermore, in order to effectively protect the opening of the trough-shaped discharge component, the mesh assembly also includes a protective mesh 14 arranged side by side with the screen 13 to jointly cover the opening of the trough-shaped storage component 12.

[0034] In this way, the entire opening can be covered by the protective net 14 and the screen 13. The protective net 14 can prevent personnel from falling into the trough-shaped storage component 12 from areas other than the material receiving port, thus enhancing safety. The screen 13 is set at one end of the opening of the trough-shaped storage component 12 and serves as the main material receiving port. The screen 13 can filter and intercept large objects in the cement slurry to prevent large objects from entering the spraying pipe of the trolley and affecting the normal operation of the equipment. The protective net 14 is set in the remaining areas of the opening of the trough-shaped storage component 12 to prevent personnel from falling into the storage component, thus improving safety.

[0035] To facilitate automatic cleaning of the storage chamber 121 of the storage component, combined with Figure 5 As shown, the trough-shaped storage component 12 is provided with flushing pipes 24 distributed circumferentially along the opening.

[0036] In this way, the storage chamber can be flushed and cleaned through the circumferentially arranged cleaning pipeline, which can replace manual cleaning and is more convenient. In the specific implementation process, the flushing pipeline 24 is connected to a water source, and can include water pipes arranged above or inside the opening of the trough-shaped storage component and distributed circumferentially, as well as several nozzles distributed in the extension direction of the water pipes, and controlled by valves, so as to realize the flushing of the storage chamber 121.

[0037] Based on this, the protective net 14 can be replaced or simultaneously installed with the trough-shaped storage component 12. The separability of the protective net 14 makes it easier to clean the trough-shaped storage component 12. The separability can be achieved by fasteners such as screws, or by other separable connection structures, and there are no restrictions.

[0038] In a preferred embodiment of the slurry anti-coagulation mechanism, a stirring shaft 22 and stirring blades 23 distributed on the stirring shaft 22 are provided in the storage chamber 121. A stirring motor 4 outside the storage component provides the power for stirring. The trough-shaped storage component 12 stores materials through the storage chamber 121. Cement slurry enters the storage chamber 121 through the inlet and maintains relatively stable fluidity under the continuous stirring action of the slurry anti-coagulation mechanism. During the shotcreting operation, cement can be drawn out from the outlet of the trough-shaped storage component by an external pumping device for shotcreting.

[0039] Please refer to Figure 2-4 As shown, in the embodiments of this application, a posture adjustment component 15 may also be included. The trough-shaped material storage component 12 is movably mounted on the support frame 11. The posture adjustment component 15 drives the trough-shaped material storage component 12 to adjust the pitch angle in the direction toward the discharge port.

[0040] The attitude adjustment component 15 is used to adjust the pitch angle of the trough-shaped storage component 12 in the direction of the discharge port. When there is little cement slurry in the trough-shaped storage component 12 and it is not easy to flow, the attitude adjustment component 15 can raise the end of the trough-shaped storage component 12 away from the discharge port. In this way, the internal cement slurry can be gathered at the end with the discharge port and discharged by adjusting the pitch angle. This can make the discharge more thorough and greatly reduce the cement slurry remaining in the storage cavity 121, and prevent this part of the cement slurry from solidifying and occupying storage space.

[0041] In specific implementation, one end of the trough-shaped storage component 12 with a discharge port is rotatably connected to the support frame 11 via a connector such as a rotating shaft 19. The other end of the trough-shaped storage component 12 is connected to the support frame 11 via the attitude adjustment component 15. The attitude adjustment component 15 drives the trough-shaped storage component 12 to switch between an inclined position and a horizontal position. The attitude adjustment component 15 allows the trough-shaped storage component 12 to rotate around the rotating shaft 19 to achieve inclination, that is, to switch between an inclined position and a horizontal position, so that the remaining material can be discharged from the discharge port. Specifically, a pumping device is also provided at the end of the trough-shaped storage component 12 with the discharge port. The input port of the pumping device is connected to the discharge port, and the storage port of the pumping device is connected to the spraying pipeline of the shotcrete trolley 2.

[0042] In addition, a support shaft 18 is provided at the end of the trough-shaped storage component 12 away from the rotating shaft 19, so as to support it on the bearing frame 11 when it is in a horizontal position, so as to prevent the trough-shaped storage component 12 from falling.

[0043] Since the end of the trough-shaped storage component 12 facing away from the rotating shaft 19 is mounted on the support frame 11 via the attitude adjustment component 15, in order to reduce the force borne by the attitude adjustment component 15 and improve the effective support of the trough-shaped storage component 12, a first support leg 16 is provided at the rotatable end of the trough-shaped storage component 12. The first support leg 16 is raised or lowered as the trough-shaped storage component 12 moves. By providing the first support leg 16 to the trough-shaped storage component 12, the first support leg 16 can provide support during fixed-point shotcreting and can also be raised by the attitude adjustment component 15 to avoid obstacles when encountering them. This avoids the need for additional telescopic or lifting mechanisms, making it more convenient and practical.

[0044] Based on this, alternatively or simultaneously, the support frame 11 is provided with several second support legs 17. The second legs support the support frame 11. When the transfer storage device 1 provides slurry at a fixed point, they support the support frame 11 and the trough-shaped storage component 12 on it. When the transfer storage device 1 moves synchronously with the shotcrete trolley 2 to provide slurry, the second support legs 17 are retractable, allowing them to easily avoid obstacles during movement by retracting. The retractable second support legs 17 on the support frame 11 can support the trough-shaped storage component 12 carrying a large amount of cement slurry during fixed-point shotcreting, reducing the stress at the connection between the support frame 11 and the trolley, making the transfer storage device 1 more stably and reliably connected to the trolley. When the equipment moves and the trough-shaped storage component 12 is lightly unloaded, it can retract to avoid obstacles, making movement more flexible and convenient.

[0045] Specifically, the attitude adjustment component 15 may include a hydraulic cylinder, with its two ends connected to the support frame 11 and the trough-shaped storage component 12, respectively, thus enabling adjustment of the pitch angle. Alternatively, a hydraulic mechanism can be used as a retractable second support leg 17, which can support the transfer storage device 1.

[0046] To improve the overall structural stability of the trough-shaped storage component 12 for better load-bearing capacity, combined with Figure 2 , Figure 3 and Figure 5 As shown in the embodiment of this application, a reinforcing frame 26 is provided on the outer side of the trough-shaped storage component 12. The reinforcing frame 26 includes a main body covering the outer surface of the trough-shaped storage component 12 and multiple support beams 261 spanning above the receiving port. The trough-shaped storage component 12 is semi-circular or U-shaped, and the reinforcing frame 26 is also semi-circular or U-shaped. The reinforcing frame 26 is welded to the outer surface of the trough-shaped storage component 12. The support beams 261 spanning the receiving port facilitate the installation and support of the protective net 14 assembly, and also make the connection of the main body structure more reliable. Thus, the reinforcing frame 26 supports the weight of the trough-shaped storage component 12, which weighs more than ten tons after being filled with cement slurry.

[0047] In addition, to facilitate the installation of the trough-shaped storage component 12 inside the support frame 11, combined with Figure 4As shown, the support frame 11 may include a main frame with a disassembly port and a mounting beam 111 detachably connected to the disassembly port. When the mounting beam 111 is separated from the main frame, the trough-shaped storage component 12 can be installed into the main frame through the disassembly port. By setting the beam component at one end of the support frame 11 as a detachable connection structure, during assembly or replacement, the mounting beam 111 can be removed first, and then the trough-shaped storage component 12 can be installed into the support frame 11 or removed, which facilitates disassembly and assembly. Specifically, the mounting beam 111 can be connected to the main frame of the support frame 11 by fasteners such as bolts.

[0048] The vibrating motor 20 installed on the screen 13 facilitates the passage of cement slurry through the screen 13. Because the screen 13 is equipped with the vibrating motor 20, it is relatively heavy and can be fixed compared to the protective net 14. To adjust the gap between the trough-shaped storage component 12 and the support frame 11, a slider 21 that can slide along the length direction can be installed on one side of the support frame 11. The top of the slider 21 abuts against the bottom of both sides of the reinforcing frame 26 of the trough-shaped storage component 12.

[0049] Please refer to Figure 1 and Figure 3 As shown, an embodiment of this application also provides a shotcrete trolley 2, including a frame and a transfer and storage device 1 as described in any of the above technical solutions, wherein the outlet of the trough-shaped storage component 12 is connected to the pumping system of the shotcrete trolley 2.

[0050] In some application scenarios, the support frame 11 of the transfer storage device 1 is fixedly connected to one side of the vehicle frame for synchronous movement. When the support frame 11 of the transfer storage device 1 is fixedly connected to one side of the frame of the shotcrete trolley 2, the transfer storage device 1 can move with the shotcrete trolley, thereby maintaining timely and rapid supply of slurry. This also reduces the need for piping and allows the shotcrete trolley, especially for integrated units, to further improve integration, without occupying space on the vehicle. The trough-shaped storage component 12 extending in the length direction can minimize the space occupied in the lateral or width directions, resulting in a more rational structural design. In specific implementation, multiple welding seats 3 can be installed on the support frame 11 near the vehicle frame. The multiple welding seats 3 are arranged in an array. Correspondingly, the frame of the shotcrete trolley 2 is also provided with corresponding connection parts, and the transfer storage device 1 is connected and fixed to the shotcrete trolley 2 by welding.

[0051] In another application scenario, the transfer storage device 1 does not move synchronously with the shotcrete trolley 2, and the outlet of the trough-shaped storage component 12 is connected to the pumping system of the shotcrete trolley 2 via an extension pipe. In this scenario, the transfer storage device 1 provides fixed-point material supply and does not move with the shotcrete trolley 2. Specifically, it is connected to the pumping system of the shotcrete trolley 2 via an extension pipe, thereby enabling continuous material supply from the transfer storage device 1 to the shotcrete trolley 2.

[0052] During construction, cement mixer trucks can transport cement slurry to the transfer storage device 1 in advance. When cement slurry is needed for shotcreting, the switch device 25 of the discharge port of the trough-shaped storage component 12 is opened to discharge the cement slurry into the pumping device. The driver does not need to wait for the shotcreting to be completed; he can simply pour the cement slurry into the trough-shaped storage component 12 and leave the tunnel, reducing the driver's waiting time and improving construction efficiency.

[0053] The trough-shaped storage component 12 has an 8m 3 The large capacity ensures that there is always material in the hopper, saving construction time and providing a guarantee for cyclical and continuous construction; the tanker truck driver only needs to transport the cement slurry to the storage tank, without having to wait for the shotcreting operation to be completed, reducing the tanker truck driver's waiting time.

[0054] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
