Abstract
Description
Technical Field
[0001] This invention relates to the field of chamber sealing technology, and more specifically, to a trolley for laying rubber sealing layers in artificial chambers. Background Technology
[0002] Artificial chambers typically refer to underground cave structures artificially excavated or constructed through engineering methods. The inner lining of these chambers requires a sealing layer. Existing technologies include trolley-type sealing material laying structures, which involve laying the material by unrolling it onto the lining. Specifically: The roll material is loaded onto the loading wheel. One end of the roll material is passed between the material sorting plate and the hot welding device and fixed on the arch surface of the chamber. Then, the traveling trolley is started, and the laying pressure roller lays the sealing material on the arch surface of the chamber. Since the sealing material is a hot melt material, the sealing material is welded to the pre-placed hot melt gasket on the arch surface of the chamber by the hot welding device.
[0003] For example, Chinese patent publications CN118911727A and CN103089281A both disclose similar structures. In the technical solution disclosed in CN118911727A, the loading wheel is set at the end of the hydraulic telescopic rod, and then a hot-melt welding device is installed on the hydraulic telescopic rod. Because the loading wheel is directly installed at the end of the hydraulic telescopic rod, the front space of the laying device is occupied by the loading wheel, which is relatively large. In the technical solution disclosed in CN103089281A, the loading wheel and the laying pressure wheel are respectively installed on the bracket, and the material sorting plate and the hot-melt welding device are installed on the inner side of the laying pressure wheel. This increases the span between the loading wheel and the laying pressure wheel, so the space required at the end of the bracket is also considerable.
[0004] It is evident that the space occupied by the end of the structure in existing technologies is relatively large. Summary of the Invention
[0005] The purpose of this invention is to provide a trolley for laying rubber sealing layers in artificial chambers, so as to solve the problem of large space occupation caused by insufficient compactness of the laying structure.
[0006] To achieve the above objectives, a trolley for laying rubber sealing layers in artificial chambers is provided, comprising: At least one track, on which a laying trolley is provided; A roll of material is fixedly connected to the rear of the laying trolley; At least one laying telescopic component is provided, which is located in front of the laying trolley, and a laying wheel is rotatably connected to the telescopic end of the laying telescopic component. as well as, At least one hot-welded expansion joint is provided, which is located in front of the laying trolley and adjacent to the laying expansion joint; a pressure block is fixedly connected to the expansion end of the hot-welded expansion joint.
[0007] The core inventive concept of the above solution lies in optimizing the space and integrating the functions of the laying structure to solve the problem of the bulky and space-consuming front end of existing equipment. This is primarily reflected in the layout structure. By fixing the large roll frame at the rear of the laying trolley, and placing the laying wheels and hot-welding blocks adjacent to the front of the trolley via their respective telescopic components, a compact module with rear-mounted material supply and front-mounted operation is formed. This layout significantly reduces the volume of the equipment's working end, enabling it to adapt to the narrow cross-section and space-constrained environment of artificial chambers, thus improving the equipment's mobility and applicability.
[0008] As a further improvement to this technical solution, the roll frame is disposed on one side of the laying trolley; Part of the roll material on the roll material rack is housed in the laying trolley.
[0009] As a further improvement to this technical solution, the hot-welded telescopic component is located on the other side of the laying trolley.
[0010] As a further improvement to this technical solution, the heat-welded expansion joint is parallel to the laid expansion joint.
[0011] As a further improvement to this technical solution, a guide structure is provided between the laying expansion joint and the hot-welding expansion joint.
[0012] As a further improvement to this technical solution, the guiding structure includes: A side frame is fixedly connected to the side wall where the expansion joint is laid; as well as, A pressure bar is mounted on a side frame, and a pressure plate is fixedly connected to the front of the pressure bar.
[0013] As a further improvement to this technical solution, side plates are provided on both sides of the pressure block.
[0014] As a further improvement to this technical solution, side plates are provided on both sides of the pressure block, and both side plates are fixedly connected to the pressure plate.
[0015] As a further improvement to this technical solution, one side of the side plate is wedge-shaped.
[0016] As a further improvement to this technical solution, at least one track includes a first track and a second track, both of which are concentrically arranged with the chamber.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: In this artificial chamber rubber sealing layer laying trolley, by placing the roll frame at the rear of the laying trolley and integrating the laying wheels and pressure blocks at the front of the trolley via adjacent telescopic components, a compact layout of the front end of the laying structure is achieved. This effectively solves the problem of large end space occupation caused by the front placement of the loading wheels or excessive spacing between components in existing technologies. This layout makes the overall structure of the equipment more streamlined and improves the passability and operational flexibility in narrow chambers. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] First embodiment, Figure 1 The image shows a rubber sealing layer laying trolley being installed inside the tunnel. The trolley is used to lay the rubber sealing layer onto the lining inside the tunnel. Specifically, an annular hot-melt steel plate 9 is pre-placed on the lining inside the tunnel. Alternatively, a hot-melt gasket can be pre-placed as in existing technologies, depending on the actual requirements.
[0022] Figure 2The laying structure on the laying trolley is shown. The main components of the laying structure are the roll frame 5, the laying wheel 10 and the pressure block 12. The roll frame 5 is used to carry the roll material. The roll material is pre-wound from the rubber sheet 14 (i.e., the rubber sealing layer). The shaft of the roll material is a replacement part and is packaged and shipped together with the roll material.
[0023] See Figure 1 and Figure 2 This embodiment provides a trolley for laying rubber sealing layers in artificial chambers, comprising: At least one track, on which a laying trolley 4 is installed; A roll of material 5 is fixedly connected to the rear of the laying trolley 4; At least one laying expansion joint 11 is provided, which is located in front of the laying trolley 4, and a laying wheel 10 is rotatably connected to the extension end of the laying expansion joint 11. as well as, At least one heat-welded expansion joint 13 is provided in front of the laying trolley 4 and adjacent to the laying expansion joint 11; a pressure block 12 is fixedly connected to the expansion end of the heat-welded expansion joint 13.
[0024] In one implementation scheme, a circular track is set up, and after the paving trolley travels into the chamber, the track is concentric with the chamber, allowing the paving trolley 4 to travel on the track. The paving trolley 4 includes a main body, which is driven by a drive wheel set at its rear end. The drive wheel set consists of a traveling wheel, a reduction gearbox, and a servo motor, and is securely mounted on the track to ensure that the paving trolley 4 can travel smoothly along the circumference of the track. The paving trolley 4 is driven by a servo motor, which transmits power to the traveling wheel through the reduction gearbox, achieving stepless speed regulation for forward or backward control.
[0025] Before laying, a certain length of rubber sheet 14 is pulled out and passed sequentially through the gaps between the laying wheel 10 and the lining, and between the pressure block 12 and the lining. The laying expansion joint 11 adapts to the curvature of the chamber wall, allowing the laying wheel 10 to roll the material against the wall with constant pressure. During laying, the roll frame 5 behind the laying trolley 4 releases the rubber sheet 14 simultaneously, and the adjacent hot-welding expansion joint 13 drives the pressure block 12 to heat and pressurize the rubber sheet 14, so that the rubber sheet 14 is welded to the hot-melt steel plate 9 or the hot-melt washer. The entire process is synchronously coordinated by the vehicle-mounted PLC controller, which controls the walking speed, laying pressure, and welding sequence.
[0026] See Figure 1In another embodiment, two tracks are provided: a first track 2 and a second track 3, arranged concentrically. Both tracks 2 and 3 are mounted on a frame 1, with multiple sets of servo motor-driven wheels 8 at the bottom. A laying trolley 4 can travel on the second track 3 to lay the rubber sheet 14. Considering that manual intervention may be required, a functional trolley 6 is provided on the first track 2. The functional trolley 6 is securely mounted on the first track 2 using another set of drive wheels. A hanging basket 7 is then placed on the functional trolley 6. A personnel platform is located under the laying trolley 4, allowing personnel on the platform to assist in removing the adhesive tape from the back of the rubber sheet 14, perform other auxiliary operations, or conduct maintenance.
[0027] Furthermore, the functional mobile cart 6 can be equipped with additional functional devices as needed, such as monitoring equipment and further processing equipment (e.g., cutting equipment, secondary extrusion equipment). Additionally, the number of tracks can be increased to accommodate more functional mobile carts 6 and functional devices.
[0028] As a further improvement, the laying trolley is equipped with an automatic lifting device, which can lift the roll material from the bottom moving trolley and install it on the roll material rack 5.
[0029] Preferably, the roll holder 5 can be equipped with a servo motor, which is controlled by a controller to realize the winding and unwinding of the roll.
[0030] See Figure 2 The roll material rack 5 is located on one side of the laying trolley 4, so that the roll material rack 5 is close to the laying trolley 4, thereby making the laying structure more compact. Moreover, part of the roll material on the roll material rack 5 is accommodated in the laying trolley 4, so that the larger volume roll material can share a part of the space with the laying trolley 4, thereby reducing the space occupied by the roll material.
[0031] Once the position of the roll frame 5 is determined, the telescopic end is positioned directly in front of the laying trolley 4, and the laying wheel 10 is installed on the telescopic end of the laying telescopic component 11, which is in front of the laying trolley 4. The front-to-back arrangement of the roll and the laying wheel 10 maximizes the use of space, and the roll will not occupy the front space of the laying structure. The laying wheel 10 is located directly in front of the laying trolley 4, which is equivalent to a derivative structure of the laying trolley 4, so it does not occupy space. Moreover, the size of the laying wheel 10 itself is not large.
[0032] In addition, see Figure 2 The heat-welded expansion joint 13 is set on the other side of the laying trolley 4, so as to... Figure 2Taking the perspective as an example, the other side is the lower side of the laying trolley 4. On the one hand, because the extension end of the heat-welded expansion joint 13 is equipped with a pressure block 12, and the pressure block 12 has a built-in heating module, it can use resistance wire or hot runner. That is to say, the pressure block 12 uses the heat-welded expansion joint 13 to apply force to bond the adhesive surface 15 on the back of the rubber sheet 14 to the hot melt steel plate 9 on the lining. Therefore, the pressure block 12 can only be set on the lower side so that the laying wheel 10 above it can weld the rubber sheet 14 that has been laid first. On the other hand, the heat-welded expansion joint 13 is set adjacent to the laying trolley 4 and is not on the same side as the roll material. Moreover, the heat-welded expansion joint 13 is parallel to the laying expansion joint 11, which further optimizes the spatial arrangement of the laying structure, making the components more compact. In addition, the heat-welded expansion joint 13 is parallel to the laying expansion joint 11, which is the same as the laying trolley 4. When it is set adjacent to the laying trolley 4, it is equivalent to setting its derivative structure on the laying trolley 4.
[0033] Figure 3 The adhesive surface 15 on the back of the adhesive sheet 14 is shown. See Figure 3 The adhesive surface 15 is arranged at intervals of 1-1.5m on the back of the adhesive plate 14. The hot-melt steel plate 9 on the inner side of the lining corresponds to the adhesive surface 15 and is arranged at intervals. Similarly, the pressure block 12 also corresponds to the adhesive surface 15 and is arranged at intervals. The laying wheel 10 is not restricted.
[0034] Second embodiment, Figure 4 An improved scheme for the laying structure on the laying trolley is shown. This embodiment improves the laying structure based on the first embodiment by setting a guide structure between the laying telescopic component 11 and the hot-welding telescopic component 13. When the laying trolley 4 moves, the laying wheels 10 press the rubber surface 15 onto the hot-melt steel plate 9. At this time, the two are only initially connected. Then, under the constraint of the guide structure, the rubber plate 14 can be flattened, so that the pressure block 12 can move more smoothly, and it also prevents the rubber plate 14 from detaching from the hot-melt steel plate 9 before the pressure block 12 is welded.
[0035] See Figure 4 The bootstrap structure includes: One side frame 18 is fixedly connected to the side wall where the expansion joint 11 is laid; as well as, A pressure bar 16 is mounted on the side frame 18. A pressure plate 17 is fixedly connected to the front of the pressure bar 16. The pressure bar 16 is also located directly in front of the laying trolley 4, forming its derivative structure.
[0036] The third embodiment. This embodiment improves the pressure block 12 based on the first embodiment. Side plates 17a are provided on both sides of the pressure block 12, which press against both sides of the adhesive surface 15 on the adhesive plate 14. By squeezing the adhesive plate 14, the adhesive plate 14 on both sides of the adhesive surface 15 is sealed, thereby improving the heat welding effect.
[0037] Fourth embodiment, Figure 5 An improved scheme for the guiding structure is shown. Figure 6 The cross-sections of side plate 17a and adhesive plate 14 are shown. This embodiment improves the guide structure based on the second embodiment; see [link to second embodiment]. Figure 5 Both sides of the pressure block 12 are provided with side plates 17a, and both side plates 17a are fixedly connected to the pressure plate 17 (by...). Figure 6 (As can be seen in the lower half of the figure). In this way, the side plate 17a moves synchronously with the pressure plate 17, independent of the pressure block 12, and the pressure value applied by the pressure plate 17 and the side plate 17a to the rubber sheet 14 is between that of the laying wheel 10 and the pressure block 12, that is, higher than the laying wheel 10 and lower than the pressure block 12.
[0038] The side plate 17a isolates the temperature on both sides of the pressure block 12, thus facilitating the separation of the pressure block 12 from the previous adhesive plate 14. Furthermore, the side plate 17a is independent of the pressure block 12. (See [reference]). Figure 6 Applying moderate pressure causes the first deformed portion 14b of the rubber sheet 14 to fit into the lining, wrapping the hot melt steel plate 9 and forming a gap 19 between it and the lining. The gap 19 is then sealed. At this time, the pressure block 12 applies high pressure to the rubber sheet 14, causing the second deformed portion of the rubber sheet 14 to squeeze the molten rubber surface 15, filling the gap 19 and forming a dense welding interface that connects the rubber sheet 14 to the hot melt steel plate 9.
[0039] Preferably, one side of the side plate 17a is wedge-shaped, so that the two sides of the first deformed part 14b are tightly attached to the lining.
