Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forming water-stopping materials for underground buildings, and in particular to a precision forming device and method for water-stopping materials for underground buildings. BACKGROUND

[0002] In engineering construction, underground buildings often face water penetration problems due to their special environment. To prevent the intrusion of underground water or other water sources into underground buildings, water-stopping materials are often used to block underground water. Common water-stopping materials include waterproofing membranes, grouting materials, and water-stopping strips, which can effectively isolate water and protect the structural integrity and environmental safety of underground buildings.

[0003] Among them, the water-stopping strip is a common water-stopping material, which is usually obtained by pouring molten raw materials in a specific mold and forming by cooling. For example, the patent application with publication number CN208960278U discloses a rapid cooling and compaction water-stopping material forming device, which includes a frame, a holding tank, a conveying roller, a compaction roller, and a cold air generating device. The frame is provided with a holding tank containing waterproof coating and a conveying roller. A gap-type outlet is formed below the holding tank. A compaction roller is connected to a power source in front of the outlet. The shaft core is parallel to the plane of the waterproof material and perpendicular to the forward direction, and the side surface is in pressure contact with the waterproof material. The cold air outlet of the cold air generating device is aligned with the cooling point of the waterproof material behind the compaction roller. This device can prevent the waterproof material from adhering to the compaction roller and improve product quality.

DETAILED DESCRIPTION

[0038] The following will be combined with the Figures 1 to 11 The present application is further described in detail.

[0039] The embodiment of the present application discloses an underground building water stop material precise forming device and method, which can adapt to reciprocating movement of forming groove structure in stages. In the first stage, the forming groove vertical section is adapted, and in the second stage, the forming groove horizontal section is adapted with a larger stroke, so that the whole area of the forming groove is ensured to be free of dead angle distribution.

[0040] An underground building water stop material precise forming device, comprising a bottom frame 1, a plurality of forming frames 2 are uniformly arranged on the bottom frame 1 along the length direction of the bottom frame 1, a T-shaped forming groove is arranged in the forming frame 2, a moving frame 3 in a U-shaped structure is slidably arranged on the bottom frame 1, and the opening of the moving frame 3 faces downward, and a forming mechanism 4 matched with the forming frame 2 is installed on the moving frame 3.

[0041] The forming mechanism 4 comprises: a storage box 41 installed above the horizontal section of the moving frame 3, used for storing molten raw materials.

[0042] A lifting frame 42 is arranged below the horizontal section of the moving frame 3, and a blanking pipe 43 reciprocally moving along the width direction of the moving frame 3 is arranged on the lifting frame 42.

[0043] The bottom of the forming frame 2 is provided with a supporting spring rod 44 symmetrically arranged along the length direction of the forming frame 2, and the supporting spring rod 44 is installed on the bottom frame 1, and the forming frame 2 is installed on the corresponding two supporting spring rods 44.

[0044] The vibration assembly 45 for lifting the forming frame 2 to reciprocally vibrate along the height direction is installed on the two vertical sections of the moving frame 3.

[0045] Among them, the various driving forces involved in the subsequent text and their corresponding control technical solutions all have mature existing driving technologies as corresponding support, which are common technical means widely popularized in the industry. Their working principles, structural designs and implementation methods are well known to technicians, so they will not be described in detail in this article (except for the driving mentioned).

[0046] The storage tank 41 and the discharge pipe 43 are connected through a variable-length flexible pipe (not shown in the figure). The mobile frame 3 is driven by an external driving force to move. When the mobile frame 3 moves above the corresponding forming frame 2, the mobile frame 3 temporarily stops moving. The lifting frame 42 is driven by an existing driving force to move downward, so that the discharge pipe 43 enters the inside of the forming groove.

[0047] During the reciprocating translation operation of the discharge pipe 43, the lifting frame 42 drives the discharge pipe 43 to move upward synchronously, ensuring that the discharge pipe 43 can continuously and uniformly lay the raw materials layer by layer on the designated area of the forming groove according to the preset material distribution track and height, effectively avoiding the problem of local raw material accumulation or uneven distribution.

[0048] At the same time, the forming frame 2 matched with the forming groove continuously performs reciprocating vibration operation, so that the raw material particles in the forming groove are fully filled with gaps and adjusted in arrangement under the action of inertia, thereby realizing the densification and vibration treatment of the raw material layer. Through the above steps, not only the combination and compactness between the raw materials can be significantly improved, but also the air inside the raw materials can be effectively discharged, fundamentally reducing the risk of gaps in the cured and formed water stop strip due to internal porosity and loose combination, and ensuring the structural integrity and sealing and waterproof performance of the water stop strip.

[0049] Specifically, the storage tank 41 includes a box body 411 installed on the horizontal section of the mobile frame 3 and opening upward. A cover plate 412 is slidably arranged inside the box body 411. A fixed frame 413 is installed on the horizontal section of the mobile frame 3. A driving cylinder 414 is installed on the fixed frame 413 through a cylinder seat. The extension end of the driving cylinder 414 is fixedly connected with the cover plate 412.

[0050] During specific work, before the device starts to work, the driving cylinder 414 is started and drives the cover plate 412 to move upward, so that the cover plate 412 is separated from the box body 411. Then the molten raw material is poured into the inside of the box body 411. Then the cover plate 412 is reset through the driving cylinder 414. When it is needed to pour the raw material into the inside of the forming groove, the driving cylinder 414 is started at this time. The extension end of the driving cylinder 414 drives the cover plate 412 to move downward and extrude the raw material to fall into the inside of the forming groove through the flexible pipe and the discharge pipe 43.

[0051] It should be noted that the molten raw material will fall through the flexible pipe and the discharge pipe 43 only when the cover plate 412 moves downward and extrudes. If the cover plate 412 is stationary, the molten raw material will not fall in the inside of the discharge pipe 43.

[0052] The lifting frame 42 comprises a lifting cylinder 421 mounted at the bottom of the horizontal section of the moving frame 3, a lifting plate 422 mounted at the telescopic end of the lifting cylinder 421, a back-shaped frame 423 mounted at the bottom of the lifting plate 422, reciprocating plates 424 symmetrically arranged along the length direction of the back-shaped frame 423, and the reciprocating plates 424 are limitingly and slidingly arranged on the short section of the back-shaped frame 423, extension frames 425 mounted on the opposite surfaces of the reciprocating plates 424, and the blanking pipe 43 is arranged between the two extension frames 425, and the blanking pipe 43 is respectively mounted on the corresponding extension frame 425 at both ends.

[0053] In specific work, when the blanking pipe 43 needs to be sent into the inside of the forming groove, the lifting cylinder 421 is started at this time, and the telescopic end of the lifting cylinder 421 moves to drive the back-shaped frame 423 to synchronously descend through the lifting plate 422, and the back-shaped frame 423 moves to drive the blanking pipe 43 to synchronously descend through the reciprocating plates 424 and the extension frames 425, so that the blanking pipe 43 enters the inside of the forming groove.

[0054] In addition, a rotating shaft 426 is mounted on the outer side edge of the short section of the back-shaped frame 423 through a bearing, a gear 427 is mounted on the rotating shaft 426, a rack plate meshing with the corresponding gear 427 is mounted on the reciprocating plate 424, and a telescopic plate 428 matched with the rotating shaft 426 is mounted at the bottom of the horizontal section of the moving frame 3, and the rotating shaft 426 is rotatably arranged on the telescopic end of the corresponding telescopic plate 428 through a bearing.

[0055] In specific work, the telescopic end of the telescopic plate 428 descends through the rotating shaft 426 during the descending process of the lifting frame 42, and according to the shape of the forming groove, the working process of the blanking pipe 43 can be divided into two stages, in the first stage, the rotating shaft 426 is driven to reciprocate through the existing driving force, the reciprocating plate 424 is driven to reciprocate along the short section of the back-shaped frame 423 through the gear 427 and the rack plate meshing with each other during the reciprocating process of the rotating shaft 426, and the blanking pipe 43 can be driven to reciprocate through the extension frame 425 during the reciprocating process of the reciprocating plate 424, so that the blanking pipe 43 can uniformly lay the raw materials on the vertical section of the forming groove.

[0056] In the second stage, when the blanking pipe 43 moves out of the vertical section of the forming groove and enters the horizontal section of the forming groove, the rotating shaft 426 and the reciprocating plate 424 repeat the actions in the first stage, and the only difference is that the reciprocating stroke of the reciprocating plate 424 is greater than the reciprocating stroke of the reciprocating plate 424 in the first stage, so as to adapt to the size of the horizontal section of the forming groove, and ensure that the blanking pipe 43 can uniformly lay the raw materials on the horizontal section of the forming groove.

[0057] By accurately matching the T-shaped structure of the forming groove, the blanking step is carried out in stages, the raw materials are uniformly laid in the whole area of the forming groove, and the raw materials are more uniform.

[0058] In addition, the driving force for reciprocating vibration of the forming frame 2 can be provided by the vibration assembly 45 of the present application. Specifically, the vibration assembly 45 comprises a horizontal frame 451 mounted on the vertical section of the moving frame 3, a moving plate 452 slidingly arranged on the horizontal frame 451 and cooperating with the telescopic plate 428, a guide slope arranged on the top of the moving plate 452 and cooperating with the telescopic end of the telescopic plate 428, an elastic telescopic rod 453 mounted on the horizontal frame 451 by a fixing protrusion and used for resetting the moving plate 452, the telescopic end of the elastic telescopic rod 453 being mounted on the moving plate 452, a linkage rod 454 mounted on the side of the moving plate 452 close to the forming frame 2, and a plurality of arc-shaped protrusions 455 evenly arranged on the bottom of the forming frame 2 close to the side of the moving plate 452 along the length direction of the bottom frame 1 and cooperating with the linkage rod 454.

[0059] wherein Figure 1 The arrow direction in the above formula is the moving direction of the moving frame 3, and the telescopic end of the telescopic plate 428 is spaced apart from the top of the moving plate 452 by a certain distance to ensure that the moving plate 452 can smoothly pass through the telescopic plate 428 when the moving plate 452 is filled with materials inside the forming groove and moves to the next forming frame 2, thereby avoiding interference between the moving plate 452 and the telescopic plate 428. In specific work, when the moving frame 3 moves to the vicinity of the corresponding forming frame 2, the lifting frame 42 is lowered, the telescopic end of the telescopic plate 428 is lowered by the rotating shaft 426 during the lowering process of the lifting frame 42, and the telescopic end of the telescopic plate 428 is lowered along the guide slope during the lowering process. At this time, the moving plate 452 is slidingly driven on the horizontal frame 451 due to the guiding effect of the guide slope. In this process, the elastic telescopic rod 453 is compressed, the moving plate 452 moves synchronously to drive the linkage rod 454 to move, the linkage rod 454 moves along the surface of the arc-shaped protrusion 455 and drives the arc-shaped protrusion 455 to move upward, thereby synchronously driving the forming frame 2 to move upward, and the supporting spring rod 44 is stretched. When the linkage rod 454 passes through the bottom of the arc-shaped protrusion 455 and is separated from the arc-shaped protrusion 455, the forming frame 2 is driven to move upward due to the gravity of the forming frame 2 and the elastic return of the supporting spring rod 44.

[0060] The above-mentioned actions are repeated, and the forming frame 2 can be shaken to shake off the impurities adhered to the inner wall of the forming frame 2 to the bottom of the forming frame 2 before the materials are laid flat. The existing dust collector (not shown in the figure) is used to remove the impurities falling to the bottom of the forming frame 2, thereby improving the integrity of the subsequent materials contacting the inside of the forming groove to ensure the flatness of the surface of the subsequent materials after solidification.

[0061] It should be noted that the distance between the discharging pipe 43 and the bottom of the forming groove is greater than the shaking stroke of the forming frame 2, so as to avoid collision between the forming frame 2 and the bottom of the forming groove during the shaking process of the forming frame 2.

[0062] When it is necessary to pour material into the forming groove, at this time the downward movement of the feeding pipe 43 is synchronized with the upward movement of the back-shaped frame 423, the upward movement of the back-shaped frame 423 drives the extension plate 428 to reset synchronously, at this time the extension plate 428 contacts the limit of the moving plate 452, the elastic extension rod 453 drives the moving plate 452 to reset, and the moving plate 452 resets through the linkage rod 454 and the arc-shaped protrusion 455 to repeat the above-mentioned action, so that the forming frame 2 is vibrated synchronously when the feeding pipe 43 is used to put material, the uniformity of the material in the forming groove is ensured, and the possibility of gaps after the material is solidified is reduced.

[0063] When the material in the forming groove is filled, the moving plate 452 resets to the starting position, at this time the moving frame 3 continues to move to the next forming frame 2, at this time the linkage rod 454 and the arc-shaped protrusion 455 are contacted again, so that the material filled in the forming groove can be vibrated as a whole, and the uniformity of the material filling is further ensured.

[0064] Then, the existing drying equipment and compaction equipment are used to dry and compact the material filled in the forming frame 2, and finally the solidified water stop strip is obtained.

[0065] It should be noted that the forming groove is a through structure in the length direction of the forming frame 2, and the forming groove is clamped at both ends with a plugging block 21 matched therewith, a plurality of metal thin strips 22 are uniformly clamped on the inner wall of the forming groove along the track, so that when the water stop strip is taken out subsequently, the contact area between the water stop strip and the inner wall of the forming groove is significantly reduced through the point contact support structure formed by the metal thin strips 22 and the surface of the water stop strip, the frictional resistance in the demolding process is reduced, the problems such as surface scratching, edge damage or structural deformation of the water stop strip caused by uneven stress in the demolding process are effectively avoided, and the smooth demolding of the water stop strip along the forming track is ensured, and the structural integrity and appearance quality of the water stop strip are ensured.

[0066] The metal thin strips 22 are tightly matched with the inner wall of the forming groove, and the material will not leak out from the gap between the metal thin strips 22 and the forming groove.

[0067] Finally, referring to Figure 8 The application also provides a precise forming method for underground building water stop material, and the use method comprises the following steps: S1: starting the driving cylinder 414 of the storage tank 41, driving the cover plate 412 to move upwards, then injecting molten raw material into the tank, and then resetting the cover plate 412 to seal. When the moving frame 3 moves to the target forming frame 2 and stops stably, the lifting frame 42 moves downward, the moving plate 452 slides through the extension plate 428, the linkage rod 454 moves along the arc-shaped protrusion 455 of the forming frame 2, and the forming frame 2 moves upwards and then resets with the support spring rod 44. Repeating the action of shaking the forming frame 2, the impurities on the inner wall are vibrated and removed by the dust collector, and the obstacles for subsequent material laying are cleared.

[0068] S2: Start the lifting cylinder 421 of the lifting frame 42, drive the blanking pipe 43 to move down into the forming groove through the lifting plate 422, the back-shaped frame 423 and other structures. Then start the storage box 41 drive cylinder 414, the cover plate 412 moves down to extrude the raw material, which is transported to the blanking pipe 43 through the flexible pipe. At the same time, the lifting frame 42 drives the blanking pipe 43 to move up synchronously, the rotating shaft 426 drives the gear 427 to mesh with the rack plate, drives the reciprocating plate 424 and the blanking pipe 43 to move along the back-shaped frame 423, and first completes uniform distribution in the vertical section of the forming groove with short stroke.

[0069] S3: When the blanking pipe 43 enters the horizontal section of the forming groove, the rotating shaft 426 and the reciprocating plate 424 repeat the previous action, only increase the stroke of the reciprocating plate 424 to adapt to the size of the horizontal section, realize the full-area no-dead-angle distribution. During blanking, the moving plate 452 reciprocates under the action of the elastic expansion rod 453, the linkage rod 454 and the arc-shaped protrusion 455 cooperate to continuously drive the forming frame 2 to vibrate up and down, so that the raw material particles fill the gap and expel air.

[0070] S4: After the forming groove is filled, the moving plate 452 is reset, the moving frame 3 moves to the next forming frame 2, the linkage rod 454 contacts the arc-shaped protrusion 455 again, and the filled forming groove is vibrated again. After the distribution of all the forming frames 2 is completed, the material is treated by using the existing drying and compaction equipment, and the metal strips 22 on the inner wall of the forming groove are removed by point contact to reduce friction, and cooperate with the through structure and the blocking block 21 to make the water stop strip smoothly out of the track.

[0071] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application.
