DETAILED DESCRIPTION

[0035] The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0036] The embodiment of the present application proposes a track type gate-shaped support frame concrete cloth device, which is used for narrow linear concrete structure construction in factory building or infrastructure engineering, can be applied to a space with narrow working surface, reduces the operation difficulty of workers, improves the construction efficiency, and provides more safe operation space for workers; meanwhile, the pump pipe can be fixed in the concrete pouring process, so as to avoid concrete overflow and scattering due to pump pipe shaking; the overall structure is simple, convenient to operate, and has strong practicality.

[0037] As Figure 1As shown in the figure, this embodiment of the invention proposes a track-type portal frame concrete placing device, including a first track 4, a portal frame 5, a second track 6, and a placing mechanism 7. The first track 4 and the second track 6 are two parallel structures. The portal frame 5 spans the first track 4 and is slidably connected to the first track 4, allowing it to move along the first track 4. The portal frame 5 is equipped with an operating platform, which facilitates workers to perform concrete placing operations on the operating platform. The second track 6 is connected to the portal frame 5 and is perpendicular to the first track 4. The placing mechanism 7 is slidably connected to the second track 6, allowing it to move along the second track 6, and is equipped with a buffer 71 for connecting a concrete pump pipe. In operation, the first track 4 is set along the length of the concrete structure to be constructed. The gantry frame 5 is erected on the first track 4 and positioned above the concrete structure. The second track 6 is set on the gantry frame 5 in a direction perpendicular to the first track 4. The position of the concrete placing mechanism 7 on the second track 6 can be adjusted as needed to align the concrete placing mechanism 7 with the concrete structure from top to bottom. During pouring, the gantry frame 5 moves along the first track 4 to complete the pouring of the entire length of the concrete structure. With this technical solution, workers only need to connect the concrete pump pipe to the concrete placing mechanism 7 and adjust the position of the concrete placing mechanism 7 and control the movement of the gantry frame 5 along the first track 4 to complete the pouring of the concrete structure. This operation is convenient, significantly reducing the labor intensity and workload of workers and improving construction efficiency. Furthermore, the gantry frame 5 is equipped with an operating platform, providing workers with a safe and reliable operating space and improving the safety of construction operations. The concrete pump pipe is connected to the concrete placing mechanism 7, which is more stable than when the worker holds it by hand, thus avoiding concrete waste and pollution caused by pump pipe shaking.

[0038] Furthermore, in the embodiments of this application, such as Figure 2 As shown, the gantry frame 5 includes a base 51, with support portions 511 at opposite ends of the base 51. An operating platform is mounted on the support portions 511. A fabric support frame is located between the support portions 511, and a second track 6 is mounted on the top of the fabric support frame. The gantry frame 5 serves as the mounting base for the second track 6 and is preferably a frame structure to reduce overall weight. The support portions 511 are positioned opposite each other at both ends of the fabric support frame and are arranged parallel to the second track 6, serving to mount the operating platform so that workers can operate from either side of the fabric support frame as needed.

[0039] Specifically, the gantry frame 5 is welded from square steel tubing. The base 51 includes several horizontal bars parallel to the second track 6 and vertical bars at both ends of the horizontal bars. The support part 511 includes at least two horizontal bars. The fabric placing frame also includes at least two horizontal bars, and the second track 6 is installed on the horizontal bars of the fabric placing frame. Preferably, the top of the fabric placing frame is higher than the support part 511. The fabric placing mechanism 7 is installed on the second track 6, which is installed on the top of the fabric placing frame. The operating platform is installed on the support part 511, so that the fabric placing mechanism 7 is higher than the operating platform, which facilitates operation by workers.

[0040] Furthermore, in the above embodiment, the bottom of the support portion 511 is provided with a first directional wheel 52, which is rotatably connected to the first track 4 to drive the support frame to move along the first track 4. Specifically, the first directional wheels 52 are arranged in pairs opposite to each other at the bottom of two longitudinal bars located at the edge of the fabric frame, and the rolling direction is set along the length direction of the longitudinal bars. Multiple sets of first directional wheels 52 can be provided as needed.

[0041] like Figure 2 As shown, the aforementioned operating platform includes a platform plate 53 and a guardrail 54. The platform plate 53 is fixed to the support portion 511, and the guardrail 54 is connected to the side of the support portion 511 away from the fabric rack. Specifically, the platform plate 53 is made of checkered steel plate and is fixed to the crossbar of the support portion 511 in the extension direction, allowing workers to walk on it; the guardrail 54 is located on the opposite outer side of the platform plate 53 to form a safety protection; the platform plate 53 and the guardrail 54 can be welded to the support portion 511, or they can be detachably connected to the support portion 511.

[0042] like Figure 3 As shown, the buffer 71 has a funnel-shaped structure, and second directional wheels 73 are provided at opposite ends of the buffer 71. The second directional wheels 73 are rolledly connected to the second track 6. The buffer 71 is used to connect to the concrete pump pipe. By setting it in a funnel shape, it can buffer the concrete from the concrete pump pipe, reduce segregation during vertical pouring of concrete, and ensure the construction quality. By setting the second directional wheels 73, the buffer 71 can move along the second track 6.

[0043] like Figure 4As shown in this embodiment, the first track 4 and / or the second track 6 include a flat plate 61. The upper surface of the flat plate 61 is provided with a limiting groove 62 and multiple sets of connecting holes. Specifically, the limiting groove 62 is a U-shaped groove, which can be adapted to the first directional wheel 52 and / or the second directional wheel 73 to prevent the first directional wheel 52 and / or the second directional wheel 73 from lateral displacement during rolling, ensuring stable and safe movement of the gantry frame 5 and / or the fabric mechanism 7. The structures of the first track 4 and the second track 6 can be the same or different, or other structural forms adapted to the first directional wheel 52 and the second directional wheel 73 can be used; no limitation is made here. In this embodiment, the structures of the first track 4 and the second track 6 are the same, respectively made using platform plates 53 of the same width but different lengths and limiting grooves 62. The first directional wheel 52 and the second directional wheel 73 are the same size to facilitate processing. The first track 4 and / or the second track 6 are fastened to the fabric frame by bolts passing through the connecting holes.

[0044] like Figure 3 As shown, the buffer 71 is also connected to a limiting pin 74, which is used to fix the buffer 71 in a set position on the second track 6 to prevent the buffer 71 from moving during concrete pouring, causing the pouring position to deviate and improving the stability of the overall structure. Specifically, the limiting pin 74 can be directly set on the buffer 71, or it can be set on the second directional wheel 73, or other positions. It can be set to one or more, which is not limited here. In a specific embodiment, wheel seats 72 are provided at opposite ends of the buffer 71, and the second directional wheel 73 is connected to the wheel seat 72. An L-shaped bracket is also provided on one side of the wheel seat 72. The bottom end of the L-shaped bracket is provided with a horizontal connecting plate. The horizontal connecting plate has a threaded hole, and the limiting pin 74 is threadedly connected to the threaded hole. When it is necessary to fix the buffer 71 in a set position on the second guide rail, the limiting pin 74 is screwed down to move the limiting pin 74 downward and press against the second track 6, thereby fixing the buffer 71.

[0045] Furthermore, in a specific embodiment, the flat plate 61 has an elongated hole 63 that matches the limiting pin 74. The elongated hole 63 is arranged parallel to the limiting groove 62. When the buffer 71 moves, the limiting pin 74 partially extends into the elongated hole 63. When it is necessary to fix the buffer 71, the limiting pin 74 is rotated to move downward and press against the fabric frame to avoid damage to the second track 6.

[0046] Preferably, the limiting pin 74 is disposed on the outside of the limiting groove 62 to facilitate the worker's operation to lock the limiting pin 74.

[0047] Furthermore, the concrete placing frame is higher than the support 511, and the buffer 71 passes through the gap between the second tracks 6 and extends below the support 511. By setting the buffer 71, the outlet end of the concrete is as close as possible to the pouring position, which can further avoid concrete waste and pollution caused by concrete overflow when it falls.

[0048] This application also proposes a construction method using the above-mentioned track-type portal support frame concrete placing device for pouring electromechanical pipeline trenches, including the following steps:

[0049] S1. Foundation beams on both sides of the construction trench, and brick formwork 2 are built for backfilling.

[0050] Specifically, based on the geometric dimensions and elevation characteristics of the foundation beam, a brick formwork 2 is built on the outside of the trench. After the construction is completed, backfilling is carried out to reduce the difficulty of irregular shape formwork and formwork support, and the backfill soil 1 is used to form a stable structure.

[0051] S2, Support trench formwork system;

[0052] Specifically, bakelite formwork can be used as the template and pipe racks can be used for support and fixation; the template and brick formwork 2 together form the concrete pouring space of the trench;

[0053] S3. Install the first track 4;

[0054] The first track 4 is installed above the backfill soil 1 to ensure the track position and direction are accurate.

[0055] S4, assemble the gantry frame 5, the second track 6 and the fabric laying mechanism 7 into one unit, and install the assembled structure on the first track 4;

[0056] The gantry frame 5, the second track 6, and the fabric-laying mechanism 7 are assembled on the ground and then installed at one end of the first track 4.

[0057] S5. Move the concrete placing mechanism 7 to one side of the trench and connect it to the concrete pump pipe;

[0058] Move the placing mechanism 7 along the second track 6 so that the buffer 71 is aligned with the pouring space on one side of the channel. Fix the placing mechanism 7 in this position by the limiting pin 74, and then connect the concrete pump pipe.

[0059] S6. Move the gantry frame 5 along the first track 4 and pour concrete;

[0060] The concrete is buffered by the buffer 71 and poured into the pouring space. During pouring, the gantry frame 5 is pushed at a uniform speed to achieve uniform material distribution along the length of the channel.

[0061] S7. Move the cloth-laying mechanism 7 to the other side of the trench, move the gantry frame 5 along the first track 4, and pour concrete on the other side.

[0062] After the concrete is poured along the entire length of one side of the channel, the concrete placing mechanism 7 is moved along the second track 6 so that the buffer 71 is aligned with the pouring space on the other side of the channel. Then, the gantry frame 5 is moved along the first track 4 to pour the concrete on the other side of the channel.

[0063] The advantages and positive effects of this invention are:

[0064] (1) By setting up a first track, a gantry frame, a second track and a concrete placing mechanism, this application makes the pouring of narrow linear concrete structures more convenient and faster, greatly reducing the labor intensity and workload of workers and improving construction efficiency.

[0065] (2) By setting up an operating platform, a safe and reliable operating space is provided for workers, which improves the safety of construction operations;

[0066] (3) The concrete pump pipe is connected to the buffer, which is more stable than the worker holding it, thus avoiding concrete waste and pollution caused by the shaking of the pump pipe. It can also buffer the concrete in the concrete pump pipe, reduce the segregation phenomenon when the concrete is poured vertically, and ensure the construction quality.

[0067] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
