Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation pipe technology, specifically relating to an automatic feeding mechanism for thermal insulation pipes. Background Art

[0002] Precast direct-buried insulated pipes are mainly used in district heating external network pipelines. With the national promotion of centralized heating, their usage is increasing and their application scope is expanding. Precast direct-buried insulated pipes have many advantages, such as good waterproof and corrosion resistance, cost savings, shorter construction period, and low maintenance costs. Currently used precast direct-buried pipes consist of steel pipes, supports, insulation layers, and outer protective pipes. Before assembly, the steel pipes need to undergo rust removal and anti-corrosion processes. During these processes, the steel pipes need to be transported to adjacent workstations. Currently, two main methods are used for transporting steel pipes: one is by conveyor belt, but this has the following disadvantages: the transport distance of the steel pipes is relatively short, and the conveyor belt occupies a lot of space, making it unsuitable for transporting insulated pipes. The other method is by conveyor rollers, but during unloading, two workers are needed to lift the steel pipes from both ends, which is time-consuming and labor-intensive. Utility Model Content

The steel pipe moving platform and the driving mechanism are respectively fixed on the support. The driving mechanism drives the steel pipe moving platform to move on the support. The steel pipe moving platform includes a moving seat and a guide rail. The guide rail is fixed on the support. The bottom of the moving seat is slidably connected to the guide rail via a slider. A lifting cylinder is provided at the bottom of the support. A push block is fixed at the upper end of the lifting cylinder. A square hole is provided in the middle of the moving seat. When the push block moves below the square hole, it extends out of the square hole under the drive of the cylinder.

[0005] Preferably, the driving mechanism is a moving module, and the movable end of the moving module is fixedly connected to the side of the moving base through a connecting plate.

[0006] Preferably, the driving mechanism includes a motor, a conveyor belt, and two connecting wheels. The two connecting wheels are respectively installed at both ends of the bracket. The motor drives one of the connecting wheels to rotate. The conveyor belt is wound between the two connecting wheels and is fixed to the side of the movable seat through a connecting plate.

[0007] Preferably, the steel pipe moving platform and the drive mechanism are at least one.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0015] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0016] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0017] like Figure 1 and Figure 2As shown, this utility model discloses an automatic feeding mechanism for thermal insulation pipes, including a support 1, a steel pipe moving platform, and a drive mechanism 2. The steel pipe moving platform and the drive mechanism are respectively fixed on the support. The drive mechanism drives the steel pipe moving platform to move on the support. In this embodiment, the drive mechanism adopts a moving module, and the movable end of the moving module is fixedly connected to the side of the moving base through a connecting plate. The advantage of using a moving module is that since both the moving module and the moving module are purchased components, the overall operation is relatively stable. The disadvantage is that the conveying distance is relatively short, and if long-distance conveying is required, it needs to be ordered separately. In addition, if long-distance conveying of steel pipes is required, this device also involves another drive mechanism scheme. Specifically, the drive mechanism includes a motor, a conveyor belt, and two connecting wheels. The two connecting wheels are respectively installed at both ends of the support. The motor drives one of the connecting wheels to rotate, and the conveyor belt is wound between the two connecting wheels. The conveyor belt is fixedly connected to the side of the moving base through a connecting plate. The conveyor belt is driven by a motor, and a moving seat is moved by a connecting plate on one side of the conveyor belt. Although this method can transport steel pipes over long distances, its disadvantage is that the structure is somewhat complicated. Regardless of the driving method, workers can choose according to the specifications of the steel pipes.

[0018] In this device, the steel pipe moving platform includes a moving seat 3 and a guide rail 4. The moving seat is used to support the steel pipe, and the guide rail is fixed on the bracket. The bottom of the moving seat is slidably connected to the guide rail through a slider. When in use, the steel pipe is placed on the moving seat, and the moving seat moves along the guide rail. Furthermore, to achieve automatic steel pipe unloading, the device is equipped with a lifting cylinder 5 at the bottom of the support, and a push block 6 is fixed at the upper end of the lifting cylinder. A square hole 7 is provided in the middle of the moving seat. When the push block moves below the square hole, it extends out of the square hole under the drive of the cylinder. Furthermore, the upper surface of the push block is wedge-shaped. The area of ​​the push block cannot be too small and must be designed according to the size of the steel pipe. If the steel pipe is relatively short, a relatively long push block can be set. If the steel pipe is relatively long, multiple sets of lifting cylinders and push blocks can be set up at the same time to smoothly lift the steel pipe and push it down. The push block should be biased towards the lower rear side of the steel pipe, that is, off the axis of the steel pipe. When the push block rises, while lifting the steel pipe, it makes the steel pipe gradually move towards the side of the moving seat, thereby separating it from the moving seat. Some buffer platforms are set on this side so that the steel pipe can roll down smoothly.

[0019] Furthermore, in order to support the steel pipe, the upper part of the movable seat is equipped with a positioning block 8 for positioning the steel pipe.

[0020] In this device, there is at least one steel pipe moving platform and one drive mechanism. The number of steel pipe moving platforms and drive mechanisms should be selected according to the length of the steel pipe. If the steel pipe is relatively long, multiple steel pipe moving platforms and drive mechanisms should be set up, all in parallel.

[0021] In use, after the steel pipe 9 undergoes rust removal and anti-corrosion treatment on the steel pipe moving platform, the pneumatic drive mechanism moves the steel pipe to the next station. At this time, the push block below is positioned below the square hole. The pneumatic lifting cylinder drives the push block to move upward, pushing the steel pipe off the moving platform, saving time and effort.

[0022] It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
