Description

Technical Field

[0001] This utility model relates to the field of concrete technology, specifically to a production and transportation device for precast concrete components. Background Technology

[0002] Precast concrete pipes are tubular structural components widely used in municipal drainage, stormwater and sewage separation, water supply, and underground integrated pipe corridor projects. The production process of precast concrete pipes typically includes multiple stages such as mold making and casting, initial setting and curing, demolding, steam curing, finishing, painting, hydrostatic testing, inspection and warehousing, storage in a stockyard, and loading and shipping. Due to the physical spatial differences between these stages, the concrete pipes must be transferred multiple times to ensure seamless process flow and operational efficiency.

[0003] Currently, pipeline transportation mainly includes hoisting and forklift handling. During hoisting, slings, hooks, or clamps are used to directly lift the pipeline. In forklift handling, the pipeline is often placed directly on wooden blocks, steel supports, or the ground, and moved horizontally by the forklift's forks. However, because concrete pipelines are initially hard and brittle, uneven stress and pipe rolling during actual transportation can easily lead to quality defects such as cracks, chipped edges, and broken corners, severely impacting product qualification rates. Furthermore, existing transportation methods struggle to effectively balance pipeline protection with the efficiency of multi-station handling, and also suffer from problems such as improper selection of lifting points, overturning, and cumbersome operations.

[0004] Therefore, it is necessary to study a production and transportation device for precast concrete components. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a production and transportation device for precast concrete components, which can effectively solve the problems of low handling efficiency and easy damage to existing precast concrete pipes during the production process.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A precast concrete component production and transportation device includes a guide rail, a base bracket, a transport frame, and a pipe support. Two sets of guide rails are laid in parallel. The bottom of the base bracket is rotatably equipped with a track wheel, and is moved on the guide rail by the track wheel; Limiting supports are provided on both the left and right sides of the base bracket. The transport frame is arranged on the base bracket and is limited between two limiting supports; Multiple sets of pipe supports are fixed at intervals on the left and right sides of the transport frame; Both the top of the limiting bracket and the top of the pipe bracket are provided with semi-circular grooves for jointly supporting the upper opening of the pipe.

[0007] Furthermore, support platforms are fixed on both the front and rear sides of the upper end of the base bracket to support the transport frame.

[0008] Furthermore, limit plates are fixed to both the left and right end faces of the transport frame. The limit plates are attached to the inner surface of the limit support and extend downwards to limit the distribution between the front and rear support platforms.

[0009] Furthermore, the support platform is provided with a through fork tooth opening for the fork teeth of the forklift to enter.

[0010] Furthermore, a bottom support plate for direct contact with the pipe is fixed on the bracket, and the bottom support plate is a semi-circular shape with an opening at the top.

[0011] Furthermore, lifting rings are fixed on both the front and rear sides of the transport frame.

[0012] Furthermore, handles are fixed on both the front and rear sides of the limiting support.

[0013] The beneficial effects of the above technical solution are: This utility model features a detachable transport frame mounted on a base bracket, with multiple pipe supports fixed to the transport frame. Combined with limiting supports on both sides of the base bracket, the tops of both the pipe supports and the limiting supports are provided with semi-circular grooves, which together fit against the outer surface of the pipe, achieving stable multi-point support and positioning of the pipe.

[0014] The transport frame's limiting mechanism is located between the two limiting supports of the base bracket, allowing it to move horizontally along the guide rails with the base bracket, facilitating transfer between production processes. When the pipeline needs to be transferred to other processes or work points, the transport frame can be lifted as a whole using hoisting equipment or a forklift, allowing the pipeline to be transferred together with the transport frame. There is no need to directly hang or clamp the pipeline body, avoiding quality problems such as point pressure damage and external wall impact on the pipeline, thus improving the transfer efficiency and finished product qualification rate of precast concrete pipeline products in the production line.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: This embodiment aims to provide a concrete precast component production and transportation device, which is mainly used for the transfer during the production of precast concrete pipes, addressing the problems of low handling efficiency and easy damage to the pipes in the existing precast concrete pipe production process.

[0018] A precast concrete component production and transportation device, such as Figure 1 It includes guide rail 1, base bracket 2, transport frame 3 and pipe support 4.

[0019] Two sets of guide rails 1 are laid in parallel, such as Figure 1-5 The bottom of the base bracket 2 is rotatably equipped with track wheels 201, and is moved on the guide rail 1 via the track wheels 201 to facilitate the horizontal transport of the pipe 6. Three sets of track wheels 201 are spaced apart in the left-right direction on the base plate to ensure the smooth transport of the base bracket 2.

[0020] Limiting supports 5 are fixedly installed on both the left and right sides of the base bracket 2. The limiting supports 5 are made of flat steel plate structure. Support platforms 202 are fixed on the front and rear sides of the upper end of the base bracket 2 to support the transport frame 3. Handles 204 are fixed on the front and rear sides of the limiting supports 5 to facilitate manual pushing and transport.

[0021] The transport frame 3 is arranged on the base bracket 2 and is positioned between two limiting supports 5. Specifically, limiting plates 301 are fixed to both the left and right end faces of the transport frame 3. The limiting plates 301 are distributed and adhere to the inner surface of the limiting supports 5, with the inner surface being the side where the two sets of limiting plates 301 approach each other, thereby restricting the left and right movement of the transport frame 3. The limiting plates 301 extend downward and are positioned between the front and rear support platforms 202 to restrict the forward and backward movement of the transport frame 3, allowing the transport frame 3 to move together with the base bracket 2 on the guide rail 1. If necessary, additional detachable limiting structures, such as pins, can be provided to achieve stable transportation of the transport frame 3.

[0022] Two sets of pipe supports 4 are fixed on the left and right sides of the transport frame 3. The pipe supports 4 adopt a flat steel plate structure. The top of the limiting support 5 and the top of the pipe support 4 are both provided with semi-circular grooves 401 for jointly supporting the pipe 6. That is, the limiting support 5 and the pipe support 4 can jointly provide multi-point support for the pipe 6. However, it should be noted that the pipe support 4 plays the main supporting role, and at least two sets should be set to ensure that they can individually support the pipe 6.

[0023] In this example, a bottom support plate 402 for direct contact with the pipe 6 is fixed on the groove 401 of the pipe support 4. The bottom support plate is a semi-circular shape with an open top and extends in the left-right direction to reduce stress concentration. Several ribs are also fixed circumferentially between the bottom support plate 402 and the pipe support 4 to improve the stability of the bottom support plate 402. In this embodiment, the pipe support 4 is not installed on the groove 401 of the limiting support 5. The groove 401 on the limiting support 5 and the bottom support plate 402 on the pipe support 4 simultaneously contact the pipe 6.

[0024] Lifting rings 302 are fixed on both the front and rear sides of the transport frame 3 for lifting by gantry cranes and other lifting mechanisms. The support platform 202 has a through fork tines 203 for the forks of a forklift to enter. When the pipe 6 needs to be transferred to other processes or work points, the transport frame 3 only needs to be lifted as a whole by lifting equipment or forklifts to separate the transport frame 3 from the base frame 2. The pipe 6 can then be transferred together with the transport frame 3. The lifting rings 302 on the transport frame 3 can be used directly as lifting points or the transport frame 3 can be used directly as a raft. There is no need to directly hang or clamp the pipe 6 body, avoiding quality problems such as point pressure damage and external wall impact on the pipe 6. This improves the transfer efficiency and finished product qualification rate of the precast concrete pipe 6 in the production line.
