Description

Technical Field

[0001] The invention relates to the technical field of concrete prefabricated component production, and particularly discloses a mobile PC component pre-buried pipeline fixing device. Background Art

[0002] During the production of prefabricated PC components, pre-buried pipelines need to be arranged in advance. The specific operation process is to first use wire to connect it to the steel skeleton, and then bend the two ends of the pipeline upwards to a certain height to prevent concrete from entering the pipeline and causing blockage during the pouring process. The mixed concrete is then poured into the mold for solidification and molding, and finally the ends of the pipeline are cut to a fixed length. Especially in the production process of prefabricated wall panels, multiple pipelines need to be pre-buried and fixed at the same time, and the pipelines must be concentrated on one side of the wall panel and led outward. When the operators operate on the ends of the pipelines, it is difficult to align the upper ends of multiple pipes and they cannot remain in a vertical upward state. In addition, the impact during the concrete pouring process can easily cause the ends of the pipes to tilt and bend, and they need to be tied one by one with wire. The operation process is very complicated. After the concrete solidifies, the ends of the pipelines need to be cut one by one to ensure that the ends of a row of pipelines are neat.

[0003] The invention patent with application number 202310483242X discloses a device for fixing pre-embedded pipe parts, comprising a base, a motor fixedly mounted on the base, a support rod mounted on the motor via a circular plate, a telescopic rod mounted horizontally on the upper end of the support rod, a telescopic cylinder for controlling the extension and retraction of the telescopic rod mounted on the telescopic rod, a lifting cylinder mounted on the lower right end of the telescopic section of the telescopic rod, and an internal support mechanism for internal support of the pre-embedded pipe part symmetrically connected to the bottom end of the lifting cylinder via a mounting plate. The pre-embedded pipe part fixing device provided by this invention controls the internal support mechanism to provide flexible internal support to the pre-embedded pipe part through the cooperation of the motor, the telescopic rod, and the lifting cylinder, but this device is not applicable when pre-embedding and fixing multiple pipelines. In addition, when fixing the curved end of the pipe, the device cannot prevent concrete from entering the pipe and causing blockage, and after the prefabricated part is solidified and formed, its end needs to be manually cut to a fixed length, and the entire operation steps are complicated and cumbersome. Based on this, the present application proposes a mobile PC component pre-embedded pipeline fixing device that can effectively solve the above-mentioned technical problems. Summary of the Invention

[0004] The present invention aims to provide a mobile PC component embedded pipeline fixing device to solve the shortcomings of existing pipeline embedded component fixing devices in the process of positioning and pouring multiple embedded pipe components.

[0005] The present invention is achieved through the following technical solutions:

[0006] The inflatable tube is located in the airtight container and has an inflatable airbag which is adapted to move along the inflatable tube to the cam, and an air outlet is located in the airtight container, and the inflatable tube has an inflatable airbag which is adapted to move along the inflatable tube to the cam.

[0007] As a further arrangement of the above scheme, the inner wall of the cover body is provided with a first slide rail, the movable seats are all provided on the first slide rail, the middle movable seat is fixedly connected to the first slide rail, the other movable seats are all slidably connected to the second slide rail, a row of movable seats is connected with a fork-type telescopic frame, and the cover body is provided with a first telescopic member connected to the outermost movable seat.

[0008] As a further configuration of the above solution, the inner wall of the cover body is provided with a second slide rail, and the second telescopic member is slidably arranged on the second slide rail.

[0009] As a further arrangement of the above scheme, a guide cylinder is fixed on each of the movable seats, and the pipe head positioning rod is arranged along the wire tube and passes through the movable seat. The upper end diameters of the pipe head positioning rod and the guide head rod are both smaller than the inner diameter of the embedded pipeline, and the lower end of the guide head rod is arranged in a radially contracted frustum shape.

[0010] As a further arrangement of the above scheme, the cover body is rotatably connected to two drive shafts located on both sides of a row of pipe head positioning rods, each drive shaft is connected to a tool holder, the end of the tool holder is connected to a cutting knife for cutting the embedded pipeline under the guide head rod, and the cover body is provided with a drive assembly for realizing synchronous reverse rotation of the two drive shafts.

[0011] As a further arrangement of the above scheme, the drive assembly includes a third telescopic member, the end of the third telescopic member is connected to a U-shaped bar, both sides of the U-shaped bar are provided with tooth surfaces, and the two drive shafts are provided with gears meshing with the corresponding tooth surfaces.

[0012] As a further configuration of the above solution, rails are provided on the bases on both sides of the component mold, and the lower ends of both sides of the gantry are matched with the corresponding rails.

[0013] As a further arrangement of the above scheme, a long strip opening perpendicular to the track is opened at the upper end of the gantry, the cover body is arranged in the long strip opening, an adjusting screw rod is rotatably arranged at the upper end of the gantry, one end of the adjusting screw rod is connected to a handwheel, and a protrusion is provided on the cover body which is threadedly connected to the adjusting screw rod.

[0014] During use of the mobile PC component pre-buried pipeline fixing device disclosed in the present invention, the operator first arranges the pre-buried pipelines in the component mold according to the routing requirements and ties them to the steel frame with wire. The upper ends of the pre-buried pipelines are then bent upward to a certain height, with the ends of multiple pre-buried pipelines concentrated at one end of the component mold. The operator then moves the gantry along the track to align longitudinally with the pre-buried pipeline ends based on their positions. The operator then rotates the handwheel to move the cover laterally until it is aligned with the pre-buried pipeline ends.

[0015] When the cover is located directly above the end of the embedded pipe, the first telescopic member is controlled to extend or shorten according to the distance between the pipes. Then, under the action of the fork-type telescopic frame, the spacing of each movable seat is adjusted to the same as the pipe spacing. The position of the pipe head positioning rod is fine-tuned by the hand wheel so that the pipe head positioning rod is aligned with the end of the corresponding embedded pipe fitting. Then, the second telescopic member is activated to push the pipe head positioning rod downward until the inflatable rubber layer is completely inserted into the end of the embedded pipe fitting.

[0016] The air pump is then activated to inflate each inflatable rubber layer. Under the action of the gas, the rubber layer slowly expands and adheres tightly to the inner wall of the embedded pipe. This expansion helps correct the bent end of the embedded pipe, keeping it perfectly vertical. Furthermore, it completely seals the end of the embedded pipe, effectively preventing concrete from entering the embedded pipe beneath the rubber layer during subsequent pouring.

[0017] Finally, after the concrete in the component mold solidifies, the third telescopic part is directly started to move the U-shaped bar upward or downward. During the movement of the U-shaped bar, the gears on both sides will engage simultaneously to make the two drive shafts rotate synchronously in opposite directions. Then, under the action of the drive shaft, the two tool holders and the cutting knife will rotate downward until the blade of the cutting knife acts on the embedded pipeline under the guide rod, and then the upper ends of a row of embedded pipelines can be cut off at the same horizontal height.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The embedded pipeline fixing device disclosed in the present invention can be adjusted longitudinally and transversely according to the arrangement position of the embedded pipeline in the PC component during use, so that it can be used to fix the ends of the embedded pipelines in different arrangement conditions. In addition, through the design of multiple movable seats with adjustable spacing, pipe head positioning rods, guide head rods and other components, the ends of multiple embedded pipelines in the component mold can be fixed synchronously. The entire device has a wide range of applications and a high fixing speed for embedded pipe fittings.

[0020] The embedded pipeline fixing device disclosed in the present invention fixes the end of the embedded pipeline, utilizes the action of the cylinder to insert the guide rod and the gas-expanding rubber layer into the pipeline, and then uses the air pump to inflate the gas-expanding rubber layer. The gas-expanding rubber layer can not only correct the inclined bent end of the embedded pipe fitting, but also completely seal the end of the embedded pipe fitting, effectively preventing concrete from entering the embedded pipe fitting below the gas-expanding rubber layer and causing blockage during the subsequent pouring process, thereby ensuring the patency of the embedded pipeline in the entire PC component and facilitating the construction and routing during the PC component building assembly process.

[0021] The embedded pipeline fixing device disclosed in the present invention can cut off the ends of a row of embedded pipelines to a fixed length by using the synchronous action of the tool holders and the cutting knife on both sides after the concrete in the component mold is solidified, without the need for operators to cut them one by one. The ends of the embedded pipelines after cutting can be guaranteed to be neat and consistent, which is convenient for subsequent lifting, transportation or construction.

[0030] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Figures 1 to 7 , and describes the application in detail with reference to embodiments. Example 1

[0032] Example 1 discloses a mobile PC component embedded pipeline fixing device, refer to the attached Figure 1 and attached Figure 2 The apparatus includes a base 200 for mounting a component mold 100. The component mold 100, shown in this illustration, is enclosed by two longitudinal side panels 101 and two transverse side panels 102, forming a space within which the prefabricated wall panels are located. Tracks 201, parallel to the longitudinal side panels 101, are located on both left and right ends of the base 200's upper surface. A gantry 300 is movably mounted on the two aligned tracks 201. The left and right lower ends of the gantry 300 mate with corresponding tracks 201, allowing the entire gantry 300 to move along the tracks 201.

[0033] The upper end of the gantry 300 is provided with an elongated opening 301, perpendicular to the track 201. A cover 400 is positioned within the elongated opening 301. A rotating seat is also provided on each of the upper and lower ends of the gantry 300. An adjustment screw 302 is positioned between the two rotating seats, with a handwheel 303 positioned at one end of the adjustment screw 302. A protrusion 401 is fixed to the cover 400, with a threaded hole formed in the protrusion 401 that matches the adjustment screw 302. By rotating the adjustment screw 302, the operator can move the cover 400 laterally within the elongated opening 301, thereby adjusting the cover 400's lateral position.

[0034] Reference Attachment Figure 3 and attached Figure 4A first slide rail 402 is fixed on the transverse inner wall of the cover body 400, and then a row of movable seats 403 are arranged at intervals on the first slide rail 402. The middle movable seat 403 is fixedly connected to the first slide rail 402, and the other movable seats 403 are slidably arranged on the first slide rail 402. A fork-type telescopic frame 404 is connected to the upper surface of the row of movable seats 403, and then a first cylinder 405 is installed on one side of the cover body 400, and the end of the first cylinder 405 is connected to the outermost movable seat 403, so that under the action of the first cylinder 405 and the fork-type telescopic frame 404, the row of movable seats 403 can be synchronized with each other or move away from each other along the first slide rail 402 with the fixed movable seat 403 as the center.

[0035] A guide cylinder 406 is fixed to each movable seat 403. A pipe head positioning rod 407 is vertically inserted into each guide cylinder 406 and extends through the movable seat 403. The diameter of the pipe head positioning rod 407 is smaller than the inner diameter of the pre-buried pipeline. A second slide rail (not shown) is also fixed to the transverse inner wall of the gantry 300 and is arranged parallel to the first slide rail 402. A row of second cylinders 408 are slidably arranged on the second slide rail, and the second cylinders 408 are aligned one by one with the movable seat 403. Then, a connector 409 is fixedly connected to the upper end of the pipe head positioning rod 407 at the end of each second cylinder 408, so that the second cylinder 408 can push the connected pipe head positioning rod 407 downward.

[0036] Reference Attachment Figure 5 Each pipe head positioning rod 407 is provided with an inflation channel 4071 along its central axis. The lower end of the inflation channel 4071 is connected to an inflation tube 410. The lower end of the inflation tube 410 is connected to a guide rod 411. The upper end of the guide rod 411 has the same diameter as the pipe head positioning rod 407, and the lower end is in a radially contracted frustum shape, which facilitates the insertion of the guide rod 411 into the embedded pipe 600. An inflatable rubber layer 412 is connected between the pipe head positioning rod 407 and the guide rod 411, and the inflation tube 410 is located within the inflatable rubber layer 412. A plurality of air outlet holes are also provided on the circumferential surface of the inflation tube 410.

[0037] Finally, an air pump 500 is provided at the upper end of the cover body 400, and the end of the air pump 500 is connected to the air tube 501, and the upper end of the air channel 4071 of each pipe head positioning rod 407 is connected to the air tube 501 through a hose. The air tube 501 is also provided with a corresponding air valve (not shown in the figure). The air pump 500 can inject high-pressure gas into the air channel 4071, and the high-pressure gas is then discharged from the air outlet on the air tube 410, causing the air-expanding rubber layer 412 that was originally in a contracted state to begin to expand. Under the action of the expansion of the air-expanding rubber layer 412, the end of the embedded pipeline is sealed to prevent a small amount of concrete from entering the embedded pipeline 600 and clogging it during the pouring process. Example 1

[0038] Example 2 discloses a mobile PC component embedded pipeline fixing device that is optimized based on the technical solution in Example 1. It is mainly designed to address the problem that after the PC component is solidified and formed, the operator needs to cut the ends of the embedded pipelines one by one. The similarities between Example 2 and Example 1 will not be described again.

[0039] Reference Attachment Figure 3 , Attachment Figure 6 and attached Figure 7 A drive shaft 700 is rotatably connected to the inner wall of the cover body 400 on both the front and rear sides of a row of pipe head positioning rods 407. A gear 701 is fixed to the same end of each of the two drive shafts 700. A third cylinder 702 is then installed on the upper surface of the cover body 400 directly above the gears 701. The lower end of the third cylinder 702 is connected to a U-shaped bar 703 located between the two gears 701. The front and rear sides of the U-shaped bar 703 are provided with tooth surfaces that mesh with the gears 701. Driven by the third cylinder 702, the U-shaped bar 703 moves up and down. The meshing action of the gears 701 and the tooth surfaces on the U-shaped bar enables the two drive shafts 700 to rotate synchronously in opposite directions.

[0040] An L-shaped blade holder 704 is welded to each drive shaft 700. A cutting blade 705 is removably mounted to the lower end of each blade holder 704 via bolts or other fasteners. A row of notches 7051 are evenly spaced along the blade edge of each cutting blade 705, aligned with each pipe head positioning rod 407. When the third cylinder 702 controls the vertical movement of the U-shaped bar 703, the two blade holders 704, which were originally horizontal, gradually rotate downward until the ends of the two cutting blades 705 contact the pre-buried pipelines 600 below the guide rod 411. The notches 7051 then cut the upper ends of the row of pre-buried pipelines 600 at the same level.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
