Description

Technical Field

[0001] This invention relates to the field of cement pole manufacturing technology, and in particular to an automated processing equipment for precast cement poles. Background Technology

[0002] Concrete utility poles are structures used to support power transmission lines or telecommunication lines. They are usually made of cement concrete. These poles have many different designs and uses, but their main purpose is to provide support and stability to ensure that wires or cables can safely transmit electricity or data. Concrete utility poles are available in prestressed and non-prestressed types. The cross-sectional shapes of utility poles include square, octagonal, I-shaped, ring, or other irregular cross-sections. The most commonly used cross-sections are ring and square.

[0003] A search revealed a prior art device for manufacturing reinforced precast concrete poles, comprising a workbench, a fixing device, a water spraying device, and a curing device. The fixing device is located on top of the workbench, and the curing device is located inside the fixing device. A water spraying device is positioned inside the fixing device and between the first and second curing frames of the curing device. This invention, through the coordination of the workbench, fixing device, water spraying device, and curing device, first places the concrete pole to be cured into the fixing device. Then, the fixing device and the curing device work together to form a cavity. At this point, the water spraying device is activated to spray water onto the surface of the concrete pole to prevent cracks from forming during curing, thus affecting the pass rate. The curing device then cures the surface of the concrete pole. However, the following problems exist: the manufacturing and curing of the concrete pole cannot be carried out in the same equipment; the cured concrete pole requires support; and a large area cannot be cured.

[0004] To address the aforementioned issues, we propose an automated processing equipment for precast cement utility poles. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art where the manufacturing and maintenance of cement utility poles cannot be carried out in the same equipment, and the cement utility poles to be maintained need to be supported, resulting in a large area that cannot be maintained. Therefore, this invention proposes an automated processing equipment for precast cement utility poles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automated processing device for precast concrete utility poles includes a processing box containing two molds: a first mold and a second mold. Each mold has a semi-circular groove on one side. When closed, the two grooves form the cavity of the concrete utility pole. The lower ends of the first and second molds are rotatably connected. The bottom of the processing box is equipped with two vertically arranged hydraulic cylinders, a first cylinder and a second cylinder, connected to the first and second molds. The driving end of the first cylinder is rotatably connected to the lower side wall of the second mold, and the driving end of the second cylinder is rotatably connected to the lower side wall of the first mold. A third cylinder is fixedly embedded in the outer wall of the processing box. The driving end of the third cylinder is located inside the processing box and is fixedly connected to a discharge plate matching the size and position of the cavity. A discharge port is located on the side of the processing box away from the third cylinder. A rotating plate located outside the discharge port is rotatably connected to the outer wall of the processing box. A curing mechanism is provided on the upper side of the processing box.

[0008] In the aforementioned automated processing equipment for precast cement utility poles, a hydraulic cylinder four is fixedly embedded on the rotating plate, and a sealing plate for sealing the discharge port is fixedly connected to the driving end of the hydraulic cylinder four. A grouting port located above the discharge port is opened on the outer wall of the processing box, and the end of the grouting port is vertically downward and connected to the discharge port.

[0009] In the aforementioned automated processing equipment for precast concrete utility poles, the curing mechanism includes a right-angle plate fixedly connected to the upper side wall of the processing box. A curing box is fixedly connected to the lower side wall of the right-angle plate. Two adjusting mechanisms are symmetrically arranged on the lower side wall of the curing box. Each adjusting mechanism includes a fixed plate fixed to the lower side wall of the curing box. A gear is installed at the lower end of the fixed plate. A movable plate is located below the gear. The upper side wall of the movable plate has serrations that mesh with the gear. A connecting rod is fixedly connected to the end of the movable plate. A vertical rod is fixedly connected to the end of the connecting rod. A sliding rod is fixedly connected to the outer wall of the vertical rod. The end of the sliding rod is slidably inserted into the processing box. A movable rod is fixedly connected to the end of the sliding rod located inside the processing box. A return spring is fitted on the outer wall of the rod. The two ends of the return spring are fixedly connected to the outer wall of the processing box and the outer wall of the vertical rod, respectively. A guide tube is connected to the lower side wall of the curing box. A moving tube is slidably inserted into the lower end of the guide tube. A curing tube is fixedly connected to the lower end of each moving rod. An opening for the downward movement of the curing tube is opened on the upper side wall of the processing box. Multiple steam ports and water spray ports are provided on the outer wall of the curing tube. A telescopic spring is fitted on the outer wall of the moving tube. The two ends of the telescopic spring are fixedly connected to the outer wall of the moving tube and the lower end of the guide tube, respectively. A connecting column is also fixedly connected to the outer wall of the moving tube. A push plate for pushing the connecting column and the moving rod downward is fixedly connected to the outer wall of the gear. The two moving rods are symmetrically arranged on the outer side of mold one and mold two.

[0010] In the aforementioned automated processing equipment for precast cement utility poles, the curing box is equipped with a steam engine and a water tank. The water tank is equipped with a water pump. The output end of the water pump is connected to a water spray nozzle via a hose one, and the output end of the steam engine is connected to a steam outlet via a hose two.

[0011] In the aforementioned automated processing equipment for precast cement poles, the two movable rods are inclined and symmetrically arranged along the centerline of the processing box, so that when the movable rods move down, they are inclinedly inserted between the cement pole and the inner wall of the cavity.

[0012] In the aforementioned automated processing equipment for precast cement utility poles, vibration motors are fixedly installed on the outer walls of both mold one and mold two.

[0013] In the aforementioned automated processing equipment for precast cement utility poles, after mold one and mold two are closed, the rotating plate is closed and locked. Concrete is injected through the grouting port, and the concrete flows into the cavity through the discharge port. After the cavity is filled, grouting is stopped. The drive end of the hydraulic cylinder four extends into the sealing plate to seal the cavity and the grouting port. The concrete solidifies and forms in the cavity.

[0014] In the aforementioned automated processing equipment for precast cement utility poles, the outer wall of the processing box is provided with a locking structure for fixing the rotating plate. The locking structure includes a pin and a socket provided on the rotating plate and the outer wall of the processing box for the pin to be inserted.

[0015] Compared with existing technologies, the advantages of this automated processing equipment for precast concrete utility poles are:

[0016] 1. Mold 1 and Mold 2 are set in the processing box, and a curing mechanism is set on the upper side of the processing box. The cement pole is formed in the cavity. After forming, the cement pole is cross-cured on both sides by rotating Mold 1 or Mold 2, so that the forming and curing of the cement pole can be carried out in one step without the need to transfer and replace the equipment.

[0017] 2. After mold one and mold two are closed, the rotating plate is closed and fixed by inserting the pin into the insertion hole. Concrete is injected through the grouting port and flows into the cavity through the discharge port. After the injected concrete fills the cavity, the grouting is stopped. The drive end of the hydraulic cylinder four extends into the sealing plate and moves inward to seal the cavity and the grouting port. The sealing plate and the discharge plate seal both ends of the cavity, allowing the concrete to solidify and form in the cavity.

[0018] 3. Set up the curing mechanism. The drive end of the hydraulic cylinder one retracts, pulling the mold two to rotate outward, making the mold two tilted. At this time, the cement pole in the cavity will slide into the groove on the mold two, forming a large gap between the cement pole and the inner wall of the groove of the mold one. As the mold two rotates outward, the mold two will contact the moving rod, pushing the moving rod to move outward, which in turn drives the moving plate to move outward. Through the meshing of the saw teeth and gears, the gears are driven to rotate, and the end of the push plate rotates downward, pushing the connecting column and the moving pipe to move downward, so that the curing pipe moves between the cement pole and the inner wall of the groove. Start the water pump and steam engine to pump out water and steam to contact the cement pole and perform curing of the cement pole.

[0019] In summary, this invention sets the molding and curing of cement utility poles within a processing box, enabling curing without the need to change equipment, which is more convenient. During curing, the retraction of the driving ends of hydraulic cylinders one and two is performed alternately, allowing molds one and two to rotate outward intermittently. This allows the curing pipe to be inserted between the cement utility pole and the groove, causing water and steam to be sprayed out to cure both sides of the cement utility pole. The contact area between the cement utility pole and the water and steam is greatly increased, ensuring the quality of curing. Attached Figure Description

[0027] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0028] Reference Figures 1-5 An automated processing device for precast cement utility poles includes a processing box 1. The processing box 1 contains a first mold 3 and a second mold 4. Each of the first mold 3 and the second mold 4 has a groove with a semi-circular cross-section on one side. When the first mold 3 and the second mold 4 are closed, the two grooves form a cavity for the cement utility pole 22. The lower ends of the first mold 3 and the second mold 4 are rotatably connected. A vibration motor is fixedly installed on the outer wall of each of the first mold 3 and the second mold 4. After the first mold 3 and the second mold 4 are closed to form a cavity, concrete is injected for molding. The vibration motor is started at the same time as the concrete is injected to promote concrete vibration, remove air bubbles in the concrete, and ensure the quality of the molded cement utility pole 22.

[0029] The bottom of the processing box 1 is equipped with vertically arranged hydraulic cylinders 2 and 3, which are connected to mold 3 and mold 4, respectively. The driving end of hydraulic cylinder 2 is rotatably connected to the lower side wall of mold 4, and the driving end of hydraulic cylinder 3 is rotatably connected to the lower side wall of mold 3. Hydraulic cylinder 15 is fixedly embedded in the outer wall of the processing box 1. The driving end of hydraulic cylinder 15 is located inside the processing box 1 and is fixedly connected to a discharge plate that matches the size and position of the cavity. A discharge port 23 is opened on the side of the processing box 1 away from hydraulic cylinder 15. The outer wall of the processing box 1 rotates... A rotating plate 24 is connected to the outside of the discharge port 23. A hydraulic cylinder 4 is fixedly embedded on the rotating plate 24. A sealing plate 25 for sealing the discharge port 23 is fixedly connected to the driving end of the hydraulic cylinder 4. A grouting port 26 is opened on the outer wall of the processing box 1 above the discharge port 23. The end of the grouting port 26 is vertically downward and communicates with the discharge port 23. A locking structure for fixing the rotating plate 24 is provided on the outer wall of the processing box 1. The locking structure includes a pin and a hole for the pin to be inserted on the rotating plate 24 and the outer wall of the processing box 1.

[0030] After mold 1 (3) and mold 2 (4) are closed, the rotating plate 24 is closed and fixed by inserting a pin into the insertion hole. Concrete is injected through the grouting port 26 and flows into the cavity through the discharge port 23. After the injected concrete fills the cavity, the grouting is stopped. The drive end of the hydraulic cylinder 4 extends into the sealing plate 25 to seal the cavity and the grouting port 26. The sealing plate 25 and the discharge plate seal both ends of the cavity, allowing the concrete to solidify and form in the cavity.

[0031] A maintenance mechanism is provided on the upper side of the processing box 1. The maintenance mechanism includes a right-angle plate 10 fixedly connected to the upper side wall of the processing box 1. A maintenance box 11 is fixedly connected to the lower side wall of the end of the right-angle plate 10. Two adjustment mechanisms are symmetrically arranged on the lower side wall of the maintenance box 11. The adjustment mechanism includes a fixed plate 16 fixedly connected to the lower side wall of the maintenance box 11. A gear 17 is installed at the lower end of the fixed plate 16. A movable plate 9 is provided below the gear 17. The upper side wall of the movable plate 9 is provided with serrations that mesh with the gear 17. A connecting rod 8 is fixedly connected to the end of the movable plate 9. A vertical rod 7 is fixedly connected to the end of the connecting rod 8. A sliding rod 14 is fixedly connected to the outer wall of the vertical rod 7. The end of the sliding rod 14 is slidably inserted into the processing box 1. A movable rod 5 is fixedly connected to the end of the sliding rod 14 located inside the processing box 1. A return spring 6 is sleeved on the outer wall of the sliding rod 14. The two ends of the return spring 6 are respectively fixed to the outer wall of the processing box 1 and the outer wall of the vertical rod 7. The lower side wall of the curing box 11 is connected to a guide tube 18. The lower end of the guide tube 18 is slidably inserted with a moving tube 12. The lower end of the moving tube 12 is fixedly connected to a curing tube 13. The upper side wall of the processing box 1 has an opening for the downward movement of the curing tube 13. The outer wall of the curing tube 13 is provided with multiple steam ports and water spray ports. The curing box 11 is equipped with a steam engine and a water tank. The water tank is equipped with a water pump. The output end of the water pump is connected to the water spray port through a hose one. The output end of the steam engine is connected to the steam port through a hose two. The outer wall of the moving tube 12 is fitted with a telescopic spring 19. The two ends of the telescopic spring 19 are fixedly connected to the outer wall of the moving tube 12 and the lower end of the guide tube 18, respectively. The outer wall of the moving tube 12 is also fixedly connected with a connecting column 21. The outer wall of the gear 17 is fixedly connected with a push plate 20 for pushing the connecting column 21 and the moving tube 12 downward. Two moving rods 5 are symmetrically arranged on the outside of mold one 3 and mold two 4.

[0032] After the cement pole 22 is formed, the following maintenance work is carried out: First, the vibration motor is started to loosen the cement pole 22 from the inner wall of the cavity. The drive end of the hydraulic cylinder 2 retracts, pulling the mold 4 to rotate outward, making the mold 4 tilted. At this time, the cement pole 22 in the cavity will slide into the groove on the mold 4 (the groove on the mold 4 is lower). A large gap is formed between the cement pole 22 and the inner wall of the groove on the mold 3. As the mold 4 rotates outward, it will contact the moving rod 5, pushing the moving rod 5 to move outward, which in turn drives the moving plate 9 to move outward. Through the meshing of the saw teeth and the gear 17, the gear 17 is driven to rotate. The end of the push plate 20 rotates downward, pushing the connecting... The column 21 and the moving pipe 12 move downwards, causing the curing pipe 13 to move between the cement pole 22 and the inner wall of the groove. The water pump and steam engine are started, so that water and steam are pumped out to contact the cement pole 22 for curing. Water helps the cement to react and harden fully, while steam promotes the hardening of the cement by providing constant high humidity and temperature conditions, which can accelerate the early strength development of the cement. Similarly, after the mold 2 4 rotates upwards and the mold 1 3 rotates downwards, the above process can be repeated to cure the other side of the cement pole 22. By cross-curing both sides, the curing of the entire cement pole 22 can be completed. After curing, the rotating plate 24 can be opened, and the cement pole 22 can be pushed out by moving the unloading plate.

[0033] The two moving tubes 12 are inclined and symmetrically arranged along the center line of the processing box 1, so that when the moving tubes 12 move downward, they are inclined to be inserted between the cement pole 22 and the inner wall of the cavity. The moving tubes 12 are inclined, so when the moving tubes 12 move downward, they can be inserted between the inner wall of the cement pole 22 and the groove, so as not to cause the problem that water and steam cannot be fully introduced to the side of the cement pole 22 when moving vertically downward.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
