Description

Technical Field

[0001] The utility model relates to the technical field of precast piles, in particular to a soil pile precast extrusion device. Background Technique

[0002] With the annual increase in the speed of national infrastructure construction, precast piles, as a pile type with mature technology, have a large number of applications in various engineering construction fields due to their advantages such as easy guarantee of pile-forming quality, ability to bear large loads, firmness and durability, etc. According to the use requirements and construction plans, precast piles can be made in factories or on construction sites. When making precast piles, processes such as feeding, pressing piles, and discharging piles need to be carried out to complete the production of a complete precast pile.

[0003] A soil pile precast extrusion device disclosed in Chinese Patent with the publication number CN216682709U includes a main support frame and a feeding mechanism. An extrusion assembly is arranged on the upper part of the main support frame, and a forming assembly and a sleeve material assembly are arranged on the lower part of the main support frame. After the feeding mechanism injects raw materials into the forming assembly in the utility model, the extrusion assembly extends downward into the forming assembly to extrude the raw materials, and then the sleeve material assembly drives the forming assembly to move upward, realizing the integration of feeding, pressing piles, and discharging piles for precast piles, saving processes, reducing production costs, improving production efficiency, enhancing production safety, and having a relatively simple overall structure.

[0004] Aiming at the above related technologies, there are some deficiencies in this device. During actual use, due to the soil pile coming out of the extrusion cylinder under the action of gravity, this demoulding method may lead to unsmooth separation between the soil pile and the extrusion cylinder. Because there is no specific separation mechanism or control means, the soil pile may get stuck or rub against the extrusion cylinder during demoulding, resulting in unsmooth pile discharging or jamming. Therefore, it is necessary to provide a soil pile precast extrusion device to solve the above technical problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a soil pile precast extrusion device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A soil pile precast extrusion device, which includes:

[0008] A substrate, on both sides of the top of the substrate are fixedly installed support plates, on the top of the support plates are fixedly installed support frames, the top of the support frames is fixedly penetrated by a pressing oil cylinder, and the driving end of the pressing oil cylinder extends below the bottom of the support frame. The driving end of the pressing oil cylinder is fixedly installed with a pressing plate. On the opposite sides of the two support plates are respectively provided with limiting grooves.

After the soil pile is formed, the extrusion plate is controlled to rise a distance slightly but does not separate from the inside of the extrusion barrel, so that the extrusion barrel moves upward. The soil pile will automatically separate from the extrusion barrel when it is hindered by the extrusion plate, ensuring that the formed soil pile can stably separate from the bottom opening of the extrusion barrel to the top of the translation block during the upward movement of the extrusion barrel, thereby solving the problem that the soil pile falls out of the extrusion barrel under the action of gravity.

DETAILED DESCRIPTION

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0027] A soil pile prefabricated extrusion device, which includes:

[0028] A substrate 1, both sides of the top of the substrate 1 are fixedly installed with support plates 2, the top of the support plates 2 is fixedly installed with a support frame 8, the top of the support frame 8 is fixedly penetrated with an extrusion oil cylinder 7, and the driving end of the extrusion oil cylinder 7 extends below the bottom of the support frame 8. The driving end of the extrusion oil cylinder 7 is fixedly installed with an extrusion plate 9. Limiting grooves 6 are opened on the opposite sides of the two support plates 2. A fixed cavity 19 is arranged inside the substrate 1. Threaded rods 16 are rotatably installed inside the two limiting grooves 6. The bottom end of the threaded rod 16 sequentially penetrates the bottom of the inner wall of the limiting groove 6 and the top of the substrate 1 and extends into the fixed cavity 19 to be rotatably connected with a bearing installed on the bottom of the inner wall of the fixed cavity 19;

[0029] A driving mechanism is arranged inside the fixed cavity 19. Adjusting blocks 17 are sleeved on the outer walls of the two threaded rods 16, and the adjusting blocks 17 are slidably connected with the limiting grooves 6. Fixed frames 11 are fixedly installed on the opposite sides of the two adjusting blocks 17;

[0030] The adjusting block 17 is fixedly installed with an extrusion cylinder 10 through the fixed frame 11. A track 3 is fixedly installed on the top of the substrate 1. An electric slider 5 is slidably installed on the track 3. A translation block 15 is fixedly installed on the top of the electric slider 5.

[0031] Both sides of the translation block 15 are fixedly installed with fixing plates 13. Above the opposite sides of the two fixing plates 13, hydraulic telescopic rods 14 are fixedly penetrated and installed. The driving ends of the two hydraulic telescopic rods 14 are fixedly installed with arc-shaped limiting plates 12.

[0032] In one or more of the embodiments, the driving mechanism includes a worm 18, and the worm 18 is rotatably installed inside the fixed cavity 19. Threaded wheels 21 are fixedly installed on the outer walls of the bottom ends of the two threaded rods 16, and the threaded wheels 21 are meshed with the worm 18. A motor 20 is fixedly installed on one side of the substrate 1, and the driving end of the motor 20 penetrates one side of the substrate 1 and extends into the fixed cavity 19 to be fixedly connected with one end of the worm 18.

[0033] In one or more preferred embodiments, a protective box 4 is fixedly installed on one side of the substrate 1, and the motor 20 is located inside the protective box 4, providing a protective effect on the motor 20 to prevent the motor 20 from being damaged due to external collisions.

[0034] In one or more preferred embodiments, a plurality of installation grooves 22 are formed on the sliding contact surface between the adjusting block 17 and the inner wall of the limiting groove 6. A ball 23 is movably installed in the installation groove 22, and the ball 23 is in rolling contact with the inner wall of the limiting groove 6, reducing the friction between the adjusting block 17 and the limiting groove 6, improving the efficiency of the motor 20, and at the same time reducing the wear of the adjusting block 17 and increasing the service life of the adjusting block 17.

[0035] In one or more embodiments, a threaded hole adapted to the threaded rod 16 is formed at the top of the adjusting block 17, and the adjusting block 17 is threadedly connected to the threaded rod 16 through the threaded hole formed at its top.

[0036] The parts not involved in this device are the same as or can be implemented by the prior art. The electrical components mentioned in this article are all electrically connected to an external main controller and 220V mains, and the main controller can be a conventional known device such as a computer for control.

[0037] When in use, the raw material is added through the top opening of the extrusion cylinder 10, and then the extrusion cylinder 7 is controlled to start working. The driving end of the extrusion cylinder 7 drives the extrusion plate 9 to move vertically, so that the extrusion plate 9 enters the interior of the extrusion cylinder 10 through the top opening of the extrusion cylinder 10 to extrude the raw material inside the extrusion cylinder 10. After the soil pile is formed, the extrusion plate 9 is controlled to rise a distance slightly, but does not leave the interior of the extrusion cylinder 10. At this time, the motor 20 is controlled to start working, and the driving end of the motor 20 drives the worm 18 to rotate. Through the meshing action of the worm 18 and the worm wheel 21, the worm wheel 21 drives the two threaded rods 16 to rotate synchronously. Through the threaded transmission of the threaded rod 16 and the adjusting block 17, and the sliding relationship between the adjusting block 17 and the limiting groove 6, the two adjusting blocks 17 are synchronously moved vertically. The movement of the adjusting block 17 drives the extrusion cylinder 10 to move vertically through the fixed frame 11, so that the extrusion cylinder 10 moves upward, and first the soil pile is formed. The pile will fall out of the extrusion cylinder 10 under the action of gravity. Secondly, if the separation between the soil pile and the extrusion cylinder 10 is not smooth, the soil pile will move up with the upward movement of the extrusion cylinder 10. At this time, the top of the soil pile inside the extrusion cylinder 10 will contact the bottom of the extrusion plate 9 inside the extrusion cylinder 10. After being blocked by the extrusion plate 9, the soil pile will automatically separate from the extrusion cylinder 10, ensuring that the formed soil pile can stably detach from the bottom opening of the extrusion cylinder 10 to the top of the translation block 15 during the upward movement of the extrusion cylinder 10, solving the problem of the soil pile falling out of the extrusion cylinder under the action of gravity. This demolding method may cause the soil pile to separate poorly from the extrusion cylinder, ensuring the stability of the soil pile demolding until the soil pile is completely out of the way. At this time, the longitudinal movement of the electric slider 5 on the track 3 can be controlled to transport the formed soil pile to the front of the top of the base plate 1, making it convenient for the staff to take it away, and then each structure is reset to repeat the prefabrication of the soil pile.

[0038] Subsequently, during the transportation of the soil piles through the translation block 15, the soil piles placed on the top of the translation block 15 can be limited, and the hydraulic telescopic rod 14 can be controlled to start working. The driving end of the hydraulic telescopic rod 14 drives the two arc-shaped limiting plates 12 to move relative to each other to clamp and fix the bottom outer wall of the soil pile located on the top of the translation block 15, thereby ensuring the stability of the soil piles during the process of moving them out of the equipment, avoiding tipping or deviation during the removal process, and improving the transportation stability of the soil piles.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
