A device for pre-embedded pipeline in fire engineering construction

Abstract

The application provides a device for pre-embedded pipeline in fire engineering construction, belonging to the technical field of fire engineering construction, comprising a base body, a supporting plate mechanism horizontally installed on the top surface of the base body, and a mechanical mechanism vertically and fixedly installed on the top surface of the supporting plate mechanism. This structure enables the pipeline to be rotated and screwed in a firmly clamped state, completely replacing the manual screwing operation mode of the pipeline in traditional construction. The side matching block can realize multi-degree-of-freedom angle adjustment in the horizontal direction and the pitch direction. The turning mechanism driving end turning block makes the extension arm rod turn around the shaft, and the auxiliary mechanism driving turning link makes the fixed end disc deflect. The two sets of mechanisms cooperate to enable the pipeline to reach any installation angle in the three-dimensional space. Compared with the traditional fixed clamp, the device improves the pipeline positioning accuracy from centimeter level to millimeter level, effectively avoids the problems of pipeline deviation and inclination, and significantly reduces the construction rework rate.

Description

Technical Field

[0001] This invention relates to the field of fire protection engineering construction technology, and more specifically, to a device for pre-embedded pipes used in fire protection engineering construction. Background Technology

[0002] In fire protection engineering construction, pre-embedded pipelines are a core component of the fire protection system, and their installation quality directly affects the reliability and safety of the entire fire protection system. Pre-embedded fire protection pipelines within building walls, floors, and other structural elements require precise placement and fixing of the pipelines according to the design drawings during the civil construction phase. Subsequent pipeline connections and system commissioning can only be carried out after the concrete pouring is completed.

[0003] Currently, the installation of pre-buried pipes in fire protection engineering construction mainly relies on manual operation or simple auxiliary tools, which presents the following prominent problems: 1. Low pipeline positioning accuracy. Traditional construction methods often involve manually moving pipelines to the pre-buried location and then fixing them with temporary supports. Because the pre-buried space is usually quite narrow, it is difficult for operators to accurately control the horizontal position and elevation of the pipeline, leading to frequent problems such as pipeline offset and tilting. Subsequent connections require a lot of rework and adjustments, seriously affecting the construction progress.

[0004] 2. Limited Pipe Clamping and Installation Methods. Most existing pipe clamping devices are fixed or only support adjustment in one direction, failing to adapt to the needs of different pipe diameters and installation angles. In actual construction, pipes often need to be rotated and fine-tuned in multiple directions, but traditional clamps are difficult to achieve multi-degree-of-freedom adjustment. Operators need to repeatedly disassemble and reassemble, resulting in high labor intensity and low efficiency.

[0005] 3. Lack of a systematic auxiliary installation mechanism. In existing technologies, the transportation, positioning, clamping, and rotation installation of pipelines are usually completed by different tools, with a lack of effective coordination between the processes. Multiple tools are required on-site, increasing construction costs and wasting time due to process switching. Especially when pipelines require threaded connections, existing devices cannot drive the pipeline to rotate while clamping and fixing it, still requiring manual tightening, which is difficult and easily damages the pipeline threads.

[0006] 4. Poor equipment mobility. Traditional pipeline pre-embedding auxiliary devices are mostly fixed structures, which cannot be flexibly moved to different work locations as the construction progresses. When the construction area changes, the equipment needs to be re-erected, which is time-consuming and labor-intensive, and seriously restricts the continuity and flexibility of construction.

A limiting ring is horizontally clamped on the inner side of the limiting groove.

[0013] As a preferred technical solution of the present invention, the steering spindle is vertically and through-type fixedly inserted into the inner side of the fixed bearing, and the extended bottom end is fixedly connected to the output end of the bottom transmission body. The steering motor structure is fixedly installed on the top surface of the bottom transmission body, and the fixed top plate and the mounting bottom plate are arranged in parallel and superimposed on each other.

[0014] As a preferred technical solution of the present invention, the top end of the steering spindle is fixedly installed at the center of the bottom surface of the rotating support plate via a flange. The rotating support plate and the fixed top plate are arranged in parallel and superimposed on each other. The control box is fixedly installed at the center of the top surface of the rotating support plate. The remote control panel is electrically connected to the internal control equipment of the control box via a wire, and the remote control panel is snapped onto the inner side of the support frame. The main bottom gear is connected to the top surface of the rotating support plate near one end via a central shaft, and the top end of the shaft of the main bottom gear is fixedly installed at the bottom end of the support arm via a flange.

[0015] As a preferred technical solution of the present invention, the extension arm is connected to the top opening groove of the support arm through an end flipping block shaft at one end. A control cylinder structure is provided on the side of the extension arm. The side mating block is horizontally fixedly connected to the center line of the steering side plate. The output end of the clamping body is extended and connected to one end of the clamping screw. There are two clamping claws, and the two clamping claws are adjusted and clamped on the outer side of the pipe through the clamping screw. One end of the end clamping block is clamped to the inner side of the end channel, and the side screw hole of the end clamping block is threadedly connected to the outer side of the clamping screw.

[0016] As a preferred technical solution of the present invention, the bottom end of the vertical pole is fixedly connected to the top surface of the telescopic crossbar at the end away from the rotating support plate. The vertical pole and the telescopic crossbar are arranged in an L-shape relative to each other. The output end of the synchronization mechanism is connected to the top end of the inner screw. The output end of the adjusting motor extends into the interior of the synchronization mechanism to maintain mechanical connection.

[0017] As a preferred technical solution of the present invention, the internal gear structure of the transmission mechanism extends horizontally to the inner side of the side groove of the end clamping block. The gear extension side and the outer side of the rotating ring are toothed together. The end clamping block and the sealing cover are clamped together at the top and bottom surfaces of the rotating ring. The side of the rotating ring is open, and the rotating ring is fastened to the outer side of the pipe through the opening. The top end of the locking mechanism is connected to the side of the clamping inner block, and the clamping inner block is clamped to the outer side of the pipe. One end of the moving clamping block is clamped to the inner side of the vertical side groove, and the top screw hole of the moving clamping block is threaded to the outer side of the inner screw. The middle clamping block is vertically clamped to the inner side of the middle limiting groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: In the solution of this invention: 1. Two clamping claws, symmetrically engaged on the sides by a side-fitting block, open and close synchronously via the threaded drive of a clamping screw. End-clamping blocks welded to the ends of the clamping claws engage with end slots and are threadedly connected to the clamping screw, forming a triple-stabilized structure of "screw drive—clamping block guidance—claw clamping." This design not only ensures even distribution of clamping force on the outer side of the pipe, preventing pipe deformation caused by localized stress concentration, but also allows for rapid adaptation to fire-fighting pipelines of different diameters by replacing clamping screws of different specifications. One device can cover various construction needs, reducing equipment configuration costs.

[0019] 2. The vertical side groove on the side of the vertical support frame engages with the inner screw rod, and the lifting movement is achieved by an adjusting motor driven by a synchronization mechanism. The synchronization mechanism ensures that the inner screw rods on both sides lift synchronously, and the engagement of the central limit groove and the central locking block provides vertical guidance for the moving locking block. This structure allows the auxiliary installation mechanism to be precisely adjusted in the vertical direction, meeting the pipe pre-embedding requirements of different floors and elevations, with a large adjustment range and accurate positioning.

[0020] 3. The rotating ring in the auxiliary installation mechanism is fastened to the outside of the pipe through an opening. The drive motor directly drives the rotating ring to rotate via gear transmission of the transmission mechanism. Simultaneously, the locking mechanism drives the clamping inner block to lock the pipe inside the rotating ring. This structure allows for threaded installation of the pipe while it is securely clamped, completely replacing the traditional manual tightening method. The limiting ring engages in the limiting groove, and the sealing cover and end clamping block form an upper and lower clamping design, ensuring that the rotating ring will not experience axial displacement or fall off during high-speed rotation, making the rotational installation process safe and reliable. The side mating block allows for multi-degree-of-freedom angle adjustment in both horizontal and vertical directions. The flipping mechanism drives the end flipping block to flip the extension arm around its axis, and the auxiliary mechanism drives the flipping connecting block to deflect the fixed end plate. These two mechanisms work together to allow the pipe to achieve any installation angle in three-dimensional space. Compared to traditional fixed clamps, this device improves pipe positioning accuracy from centimeter-level to millimeter-level, effectively avoiding pipe offset and tilting problems, and significantly reducing construction rework rates.

The side of the rotating ring body 507 is open and is fastened to the outer side of the pipe through the opening. The top end of the locking mechanism 509 is connected to the side of the clamping inner block 510 and clamps the inner block 510 to the outer side of the pipe. One end of the moving locking block 511 is locked to the inner side of the vertical side groove 403, and the screw hole on the top surface of the moving locking block 511 is threaded to the outer side of the inner screw rod 404. The middle locking block 512 is vertically locked to the inner side of the middle limiting groove 405.

[0038] The rotating ring 507 is directly driven to rotate by the transmission motor 503 via gear transmission mechanism 502. At the same time, the locking mechanism 509 drives the clamping inner block 510 to lock the pipe inside the rotating ring 507. This structure allows the pipe to be installed by rotation thread while it is firmly clamped, completely replacing the traditional method of manually turning the pipe during construction.

[0039] Working principle: The entire device is placed on a movable equipment. The rotating support plate 201 above the main steering shaft 105 rotates horizontally around the fixed bearing 104, allowing the entire device to be oriented according to the spatial layout of the construction site, facilitating alignment with the pipe pre-buried area. After moving the equipment to the construction site, the locking function of the bottom transmission body 106 secures the device to the ground, ensuring stability for subsequent operations.

[0040] The fire-fighting pipeline to be pre-buried is hoisted to the working range of the mechanical mechanism 3. The operator sends a command to the control box 202 via the remote control panel 204, controlling the control box 202 to drive the top motor 207. The output end of the top motor 207 drives the mating gear 208 to rotate. The mating gear 208 meshes with the main bottom gear 205, thereby driving the main bottom gear 205 and the support arm 301 connected to its flange to adjust the angle on the rotating support plate 201, so that the orientation of the support arm 301 is aligned with the installation direction of the pipeline. The auxiliary mechanism 311 drives the flipping connecting block 303 to rotate around the axis, driving the fixed end plate 304 and the steering side plate 305 to adjust the angle, so that the side mating block 306 is precisely aligned with the clamping position of the pipeline. After the side mating block 306 is close to the pipeline, the clamping body 307 starts, and its output end drives the clamping screw 313 to move in the horizontal insertion direction of the inner side of the side mating block 306. When the clamping screw 313 rotates, it drives the symmetrically engaged clamping claws 308 on both sides to move relative to each other along the side of the side mating block 306. The two clamping claws 308 achieve precise opening and closing through the threaded transmission of the clamping screw 313, firmly clamping the outer edge of the pipe. The end locking block 314 welded to the end of the clamping claw 308 engages with the inner side of the end groove 312 on the side mating block 306, and is threadedly connected to the outer side of the clamping screw 313 through the threaded hole on the side of the end locking block 314, ensuring structural stability during the clamping process. When the pipe needs to be adjusted in multiple directions, the operator can control the flipping mechanism 310 and the auxiliary mechanism 311 to work together via the remote control panel 204. The flipping mechanism 310 drives the flipping block 309 to adjust the pitch angle of the extension arm 302 relative to the support arm 301. The auxiliary mechanism 311 drives the flipping connecting block 303 to deflect the fixed end plate 304 and the steering side plate 305, thereby driving the side mating block 306 and the clamped pipe to rotate horizontally. The steering side plate 305 is rotatably connected to the side of the fixed end plate 304, providing flexible freedom of movement for multi-angle adjustment of the pipe. The synchronization mechanism 406 ensures that the inner screws 404 on both sides rise and fall synchronously, thereby driving the auxiliary installation mechanism 5 to move precisely in the vertical direction, realizing fine adjustment of the pipe installation height. The center limit groove 405 provides vertical guidance and limit for the center clamping block 512, ensuring the smoothness of the movement process.

[0041] When the pipeline needs to be installed to the reserved interface via a threaded connection, the auxiliary installation mechanism 5 is switched on for operation. The drive motor 503 starts, driving the gear structure inside the transmission mechanism 502 to rotate. The gear extends to the inner side of the side groove of the end clamping block 504, and meshes with the outer side of the rotating ring 507. The moving clamping block 511 is threaded to the outer side of the inner screw 404 through its top threaded hole, and moves synchronously with the lifting and lowering of the inner screw 404; the middle clamping block 512 is vertically clamped to the inner side of the middle limiting groove 405, ensuring that the auxiliary installation mechanism 5 is smoothly guided in the vertical direction. The side of the rotating ring 507 is open, and it is fastened to the outer side of the pipeline through the opening. After the locking mechanism 509 is activated, its top end acts on the clamping inner block 510 symmetrically clamped to the inner side of the rotating ring 507, firmly clamping the pipeline inside the rotating ring 507. The drive motor 503 drives the rotating ring 507 to rotate around the pipeline axis via gear transmission of the transmission mechanism 502. The clamping inner block 510 rotates synchronously with the rotating ring 507, causing the pipeline to rotate in a fixed state, thereby realizing the threaded connection between the pipeline and the reserved interface. The sealing cover plate 505 is fixed to the top surface of the end clamping block 504 by bolts, forming a clamping structure with the end clamping block 504, stably constraining the rotating ring 507 between the top and bottom surfaces, ensuring safety and accuracy during the rotation installation process.
