Description

Technical Field

[0001] This application relates to the field of building construction, and more specifically, to a pouring equipment and a method of using the pouring equipment. Background Technology

[0002] During construction, numerous horizontal or longitudinal spatial concrete pouring operations are involved. Typical applications include: concrete pouring for horizontal support steel pipes in tunnels, backfilling of existing horizontal culverts, and filling of abandoned urban water supply and drainage pipelines. These types of construction often face the following technical challenges: limited working space, long pouring distances, difficulty in accessing large equipment, restricted personnel operation, significant safety hazards, and difficulty in ensuring pouring quality.

[0003] Currently, long-distance pump-pipe delivery is commonly used for horizontal pouring, where concrete is transported to the target work surface via a pressure pump. However, actual construction shows that this method still has significant shortcomings in terms of the quality of horizontal pouring: when the pump pipe is at a low position, insufficient pressure during pressurized delivery can lead to incomplete filling, or excessive pressure can cause grout leakage. This is especially true for large-diameter pipe applications, where pressurization becomes significantly more challenging.

[0004] Furthermore, the pumping process places high demands on the technical indicators of concrete, such as fluidity, workability, and consolidation. If pipe blockage occurs or the pump pipe is not removed in time, it will not only significantly reduce the economic efficiency of horizontal filling construction, but also seriously affect the safety and reliability of the project. Summary of the Invention

[0005] The purpose of this application is to provide a pouring equipment and a method for using the pouring equipment, which can improve the pouring quality and avoid pipe blockage.

[0006] In a first aspect, the present invention provides a casting device for casting a narrow space, comprising a vehicle body, wheels, a first connector, a second connector, an elastic member, and a pumping pipe. The vehicle body has a placement position, and a plurality of wheels are mounted under the vehicle body, with each wheel equipped with a control module for controlling the wheel's brakes. The first connector is mounted on the vehicle body, and the second connector is mounted on the vehicle body, with the second connector and the first connector being disposed opposite to each other. At least one of the second connector or the first connector is provided with a distance sensor for detecting the distance between the first connector and the second connector, and the distance sensor is signal-connected to the control module. The elastic member is supported between the second connector and the first connector. One end of the pumping pipe is mounted at the placement position, and the other end of the pumping pipe passes through the first connector and the second connector.

[0007] In an optional embodiment, the second connector includes two sub-connectors, an overflow channel is provided between the two sub-connectors, and an overflow port is provided on the sub-connector away from the first connector, the overflow port being located at the lower part of the sub-connector.

[0008] In an optional embodiment, the lower ends of both sub-connectors are provided with wear-resistant sliding plates, which are in contact with the vehicle body.

[0009] In an optional embodiment, the second connector further includes a connecting block, which is connected to each of the two sub-connectors.

[0010] In an optional embodiment, the pouring equipment further includes a baffle plate rotatably connected to the vehicle body, and the baffle plate abuts against the lower structural wall of the narrow space.

[0011] In an optional embodiment, the pouring equipment further includes a level detector, which is installed on the second connector and located below the pumping pipe.

[0012] In an optional embodiment, the pouring equipment further includes a monitor mounted on the second connector and positioned above the pumping pipe.

[0013] In an optional embodiment, the pouring equipment further includes a plurality of support members, the height of which gradually increases along the vehicle body direction. The height of the support members is lower than that of the first connecting member, and the heights of the first connecting member and the second connecting member are the same.

[0014] In an optional embodiment, the casting equipment further includes a counterweight placed on the vehicle body.

[0015] Secondly, the present invention provides a method for using a casting equipment, for implementing the casting equipment described in the foregoing embodiments. The method includes: pumping casting slurry into a pumping pipe, the casting slurry being output from the discharge end of the pumping pipe to the closed end of a narrow space, the lateral pressure of the casting slurry pushing a second connector toward a first connector, and when the distance detected by the distance sensor reaches a preset value, the control module controls the brakes of the wheels to be released, and the vehicle body moves in a direction away from the casting position under the action of the elastic element.

[0016] Compared to existing technologies, the beneficial effects of this application are:

[0017] This application uses the vehicle body as a carrier to pump grout into a narrow space through a pumping pipe. Furthermore, this application utilizes the elastic connection between the first and second connecting parts to compress and store energy through lateral pressure on the elastic parts, providing energy supply for the subsequent movement of the pouring equipment, improving the compaction level of the pouring in the narrow space, ensuring the pouring quality, and avoiding pipe blockage.

[0032] Example 1

[0033] This embodiment is applicable to the filling and pouring of narrow spaces. Here, a narrow space refers to a space where the length and height of the space to be poured have a large difference, and the height is lower than the height of the construction personnel, making it inconvenient to enter the narrow space for construction.

[0034] Please see Figures 1 to 3 This embodiment uses a horizontal, narrow space as an example for illustration. The pouring grout 20 used for filling and pouring includes, but is not limited to, liquids with a certain degree of fluidity such as cement mortar.

[0035] This embodiment provides a pouring device. It should be understood that the diameter of the narrow space is sufficient for the pouring device to enter. The pouring device includes a body 100, wheels 200, a first connecting member 300, a second connecting member 400, an elastic member 500, and a pumping pipe 600.

[0036] The vehicle body 100 is provided with a placement position. Specifically, the vehicle body 100 is provided with a placement block 121, which has the aforementioned placement position. The opening of the placement position faces upward and is used to place the pumping pipe 600 mentioned later.

[0037] In this embodiment, the vehicle body 100 includes a first sub-vehicle body 110 and a second sub-vehicle body 120, with the first sub-vehicle body 110 as the front and the second sub-vehicle body 120 as the rear. The second sub-vehicle body 120 is provided with the aforementioned placement block 121, and the second sub-vehicle body 120 is connected to the first sub-vehicle body 110.

[0038] Please see Figure 3 and Figure 4 Multiple wheels 200 are installed under the vehicle body 100, and at least one wheel 200 is equipped with a control module 210. The control module 210 controls the brake of the wheel 200. When the control module 210 controls the brake, the pouring equipment remains stationary. When the control module 210 releases the brake, the pouring equipment moves under the action of an external load.

[0039] The braking control method is as follows: a brake block 220 is set on the wheel 200, and the control module 210 is connected to the brake block 220 by signal. After receiving the braking signal, the brake block 220 brakes by friction or by engaging. It is understood that the braking method of the wheel 200 is common knowledge in the field and will not be described in detail here.

[0040] Please see Figure 2 Two wheels 200 are arranged as a group, and a group of wheels 200 are respectively arranged on both sides of the vehicle body 100. In this embodiment, two groups of wheels 200 are arranged on the second sub-vehicle body 120, and a group of wheels 200 is arranged on the first sub-vehicle body 110.

[0041] Please see Figures 1 to 3The first connector 300 is mounted on the vehicle body 100. Specifically, the first connector 300 is located between the first sub-vehicle body 110 and the second sub-vehicle body 120.

[0042] The second connector 400 is mounted on the vehicle body 100, and the second connector 400 is disposed opposite to the first connector 300. At least one of the second connector 400 or the first connector 300 is provided with a distance sensor 410. The distance sensor 410 is used to detect the distance between the first connector 300 and the second connector 400, and the distance sensor 410 is signal-connected to the control module 210.

[0043] Please see Figure 3 , Figure 5 and Figure 6 The second connector 400 includes two sub-connectors 420, with an overflow channel 401 between the two sub-connectors 420, and an overflow port 402 on the sub-connector 420 away from the first connector 300. The overflow port 402 is connected to the overflow channel 401 and is located at the lower part of the sub-connector 420.

[0044] Overflow channel 401 is used to handle part of the overflow during the pouring process. The overflow flows back to the front pouring surface through overflow port 402, reducing manual operation and making it suitable for pouring processes in narrow spaces.

[0045] The lower ends of the two sub-connectors 420 are provided with wear-resistant sliding plates 421. The wear-resistant sliding plates 421 are in contact with the vehicle body 100. The wear-resistant sliding plates 421 have a preset friction force, which enables the two sub-connectors 420 to move. When the lateral pressure of the grout 20 poured on the right side is greater than the friction force, the two sub-connectors 420 move to the left.

[0046] The second connector 400 further includes a connecting block 430, which is connected to the two sub-connectors 420 respectively.

[0047] Both the first connector 300 and the second connector 400 are plate-shaped structures.

[0048] Please continue reading. Figures 1 to 3 The elastic element 500 is supported between the second connecting member 400 and the first connecting member 300. In this embodiment, the elastic element 500 can be configured as a compression spring with a certain gap between the coils of the compression spring. When subjected to an external load, the spring contracts and deforms, storing deformation energy.

[0049] In this embodiment, when the two sub-connectors 420 move toward the first connector 300, the lateral pressure of the grout 20 is transmitted to the elastic member 500 through the second connector 400. Since the first connector 300 is fixed, the lateral pressure acts as an external load to compress the elastic member 500, causing the elastic member 500 to shrink and deform.

[0050] Please see Figure 3 and Figure 4 When the deformation reaches the preset value, the control module 210 controls the brake to be released, the elastic element 500 releases the deformation energy, the right side of the second connecting part 400 is held by the grout 20, the elastic element 500 releases energy to the left, so that the entire pouring equipment moves away from the grout 20.

[0051] This embodiment uses a distance sensor 410 to measure the real-time distance to monitor the storage of deformation energy in the elastic element 500, quantify the magnitude of deformation energy, and make a decision on rear braking for the control module 210. The operation is simple and effective, improves the level of automation, and contributes to the casting process in narrow spaces.

[0052] One end of the pumping pipe 600 is positioned at the placement location, and the other end of the pumping pipe 600 passes through the first connector 300 and the second connector 400. In this embodiment, the pumping pipe 600 can be configured as a circular pipe, and correspondingly, the contact surface between the placement location and the pumping pipe 600 is arc-shaped, as are the contact surfaces between the first connector 300, the second connector 400, and the pumping pipe 600. This maximizes the stability of the pumping pipe 600 placement.

[0053] A smooth rubber sleeve (not shown in the figure) is provided at the contact position between the pumping pipe 600 and the first connector 300, and a smooth rubber sleeve is provided at the contact position between the pumping pipe 600 and the second connector 400, so as to facilitate the necessary sliding of the pumping pipe 600.

[0054] Please see Figure 3 and Figure 6 In some embodiments, the pouring equipment further includes a baffle 700, which is rotatably connected to the vehicle body 100 and abuts against the lower structural wall of the elongated space. In this embodiment, the baffle 700 can be configured to be rotatably connected to the first sub-vehicle body 110, and the length of the baffle 700 is adapted to the width of the elongated space, meaning the baffle 700 can prevent the pouring slurry 20 from flowing to the stopping position of the pouring equipment.

[0055] Please see Figure 1 , Figure 3 and Figure 6From the current perspective, when the pouring equipment moves to the left, the baffle 700 can rotate counterclockwise within a small range, ensuring that the pouring grout 20 is blocked on the right side of the baffle 700, that is, preventing the pouring grout 20 from overflowing from the bottom. In this embodiment, during the pouring process, after pouring a certain distance, the pouring equipment reverses a certain distance, and then continues to pour the space created by the reversal, and then continues to reverse, and so on.

[0056] Please see Figure 3 , Figure 4 and Figure 5 In some embodiments, the pouring equipment further includes a level detector 800, which is installed on the second connector 400 and located below the pumping pipe 600.

[0057] In some embodiments, the pouring equipment further includes a monitor 900, which is mounted on the second connector 400 and positioned above the pumping pipe 600. The monitor 900 is configured as a video surveillance device or a CCD camera, or other device with real-time monitoring capabilities.

[0058] In this embodiment, the pouring process is monitored by a liquid level detector 800 and a monitor 900. When the pouring space is close to being full, a signal is sent to the control module 210 to achieve precise control and feedback of the front pouring surface. Finally, the front sensing area is connected and interacts with the rear stable control area to achieve control of the horizontal pouring action of the entire device.

[0059] Therefore, in this embodiment, the distance sensor 410 is used as the main discrimination condition for releasing the brake, and the liquid level detector 800 and the monitor 900 are used as auxiliary discrimination conditions for releasing the brake. This design can avoid the situation where the discrimination is not timely due to the failure of one of the instruments, resulting in a pipe blockage accident.

[0060] In some embodiments, the casting equipment further includes a plurality of support members 1000, the height of which gradually increases along the vehicle body 100, the height of which is lower than that of the first connector 300, and the height of the first connector 300 and the second connector 400 are the same.

[0061] Please see Figure 2 and Figure 3 In this embodiment, the number of support members 1000 is two. The two support members 1000 are used to support the pumping pipe 600, so that the height of the pumping pipe 600 gradually increases. This ensures the pumping of the grout 20 through the pumping pipe 600 and prevents the grout 20 from accumulating inside the pumping pipe 600, which could cause the pumping pipe 600 to bend and become blocked.

[0062] To maintain the placement of the pumping pipe 600, this embodiment may also provide a slot on the support member 1000, with the shape of the pumping pipe 600 matching the slot.

[0063] In some embodiments, the casting equipment also includes a counterweight 1100. Since the first body 110 has more components, the mass of the first body 110 is greater than that of the second body 120. The counterweight 1100 is placed on the second body 120 to balance the mass of the casting equipment, so that the casting equipment can be stably kept in a horizontal state during the casting process, and to provide feasibility for the casting equipment to reverse.

[0064] It is understandable that if the counterweight 1100 is not set, the mass of each part of the casting equipment can be kept uniform by configuring the weight of each component. For example, the mass of the second connector 400 can be configured to be greater than the mass of the first connector 300.

[0065] This embodiment makes the horizontal pouring process controllable and ensures the overall height and density of the poured material. At the same time, it reduces the construction difficulty in narrow horizontal spaces and avoids safety problems caused by personnel entering confined spaces. Through this device, construction quality, safety and efficiency are significantly improved.

[0066] Secondly, please refer to Figures 1 to 3 This invention provides a method for using a casting equipment, for implementing the casting equipment described in the foregoing embodiments. The method includes: pumping casting slurry 20 into a pumping pipe 600; outputting the casting slurry 20 from the discharge end of the pumping pipe 600 to the closed end of a narrow space; the lateral pressure of the casting slurry 20 pushes the second connecting member 400 to move towards the first connecting member 300; when the distance detected by the distance sensor 410 reaches a preset value, the control module 210 controls the brakes of the wheel 200 to be released; and the vehicle body 100 moves in a direction away from the casting position under the action of the elastic member 500.

[0067] In this embodiment, the vehicle body 100 is used as a carrier. The grout 20 is pumped into the narrow space through the pumping pipe 600. In this embodiment, the elastic connection between the first connector 300 and the second connector 400 is used to compress and store energy in the elastic member 500 through lateral pressure. This provides energy supply for the subsequent movement of the pouring equipment, improves the compaction level of the pouring in the narrow space, ensures the pouring quality, and avoids pipe blockage.
