Description

Technical Field

[0001] The utility model belongs to the technical field related to cathodic protection test piles, and particularly relates to a top pressing device for a cathodic protection test pile. Background Technique

[0002] A cathodic protection test pile is a device used to detect and evaluate the cathodic protection effect of metal structures such as pipelines, storage tanks, and underground facilities. Cathodic protection is a method to prevent metal corrosion. By applying an external current, the potential on the metal surface is reduced, thereby achieving the purpose of protecting the metal structure. The test pile is usually located near the protected object for regular inspection and maintenance.

[0003] The cathodic protection test pile is usually designed as an integral structure, and the top of the test pile is integrated with the main body part. The main purpose of this design is to ensure the integrity of the test pile, facilitate the installation and maintenance of devices such as sensors and electrodes in the cathodic protection system, and also facilitate regular inspection and testing.

[0004] Since the cathodic protection test pile is usually designed as an integral structure, and the top needs to be adjusted to a suitable shape according to different requirements, it is necessary to separately stamp and form the top of the test pile. However, when the existing forming device is used, it cannot simultaneously form test piles with different diameters, and it is necessary to stamp and form the top of each test pile one by one. This not only has low work efficiency, but also easily causes damage to the stamping die when frequently using the forming device to form a single test pile, resulting in high costs. Therefore, a top pressing device for a cathodic protection test pile is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a top pressing device for a cathodic protection test pile to solve the problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A top pressing device for a cathodic protection test pile, including a box body, an oil storage tank, a stamping cylinder, and a moving plate. The moving plate is slidably arranged in front of the box body, and a motion mechanism for forming the top of the cathodic protection test pile is arranged inside the box body;

[0007] The motion mechanism includes a screw rod, which is threadedly connected to the box body. The lower end of the screw rod is rotatably connected to a pushing plate, which is slidably connected to the box body. Two groups of connecting rods are fixedly connected below the pushing plate. The lower ends of the connecting rods are rotatably connected to a first pushing frame and a second pushing frame. Multiple extrusion blocks are rotatably connected below the first pushing frame and the second pushing frame through pin shafts. A pressing rod is arranged below the extrusion block, and a strong spring is arranged on the surface of the pressing rod;

[0008] Two sets of racks are detachably connected to the front of the pushing plate. A gear is meshed and connected to the front of the racks. A rotating shaft is fixedly connected to the inside of the gear. The rotating shaft is rotatably connected to the box body. A pushing disk and a rotating disk are fixedly connected to the surface of the rotating shaft.

[0009] Preferably, a piston rod is arranged above the pushing disk. The piston rod is slidably connected to the surface of a piston cylinder. The piston cylinder communicates with the inside of the fuel tank. The surface of the piston cylinder is communicated with an upper die through a hose. The upper die is installed below the stamping cylinder.

[0010] Preferably, a lower die is installed below the upper die. A limiting plate is detachably connected to the lower end of the rack. A sliding column is installed below the rotating disk. An air conditioner is installed on the side of the box body. The lower end of the sliding column is connected to the switch of the air conditioner.

[0011] Preferably, an extrusion plate is installed at the bottom of the pressing rod. A limiting groove is installed at the bottom of the box body. A triangular groove is formed inside the limiting groove. A plurality of through holes with different diameters are formed at the rear of the box body. A return spring is arranged on the surface of the sliding column.

[0012] Preferably, the pressing rod is slidably connected to the box body. One-way valves are installed inside the piston cylinder and the hose. A reset element is installed inside the piston cylinder. The piston cylinder is fixedly connected to the box body.

[0014] Preferably, the first pushing frame, the second pushing frame and the extrusion block are also made of high-strength materials. The triangular groove formed inside the limiting groove and the through groove formed inside the lower die are both set in shapes with different widths.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. In this utility model, the rotation of the screw rod drives the pushing plate to move downward. The movement of the pushing plate drives the first pushing frame and the second pushing frame to move downward through two groups of connecting rods. The downward movement of the first pushing frame and the second pushing frame drives multiple groups of pressing blocks to move downward. The movement of the pressing blocks can drive the pressing plate below the pressing rod to press and limit the test pile body above the limiting groove, which can improve the stability of stamping and forming the top of the test pile. At the same time, when the pushing plate moves downward, it will also drive the limiting plate to move downward through the rack.

[0017] 2. In this utility model, the rotation of the gear is driven by the meshing transmission of the rack. The rotation of the gear drives the push plate to rotate through the rotating shaft. The rotation of the push plate can intermittently push the piston rod to slide inside the piston cylinder, which can transport the lubricating oil inside the fuel tank to the inside of the upper mold through the hose, and then flow from the inside of the upper mold to the inside of the lower mold and the top of the test pile to be formed, which can reduce the heat generated during the stamping and forming of the top of the test pile, avoid large friction between the upper mold and the lower mold, and improve the service life of both. At the same time, when the rotating shaft rotates, it will also drive the rotating disk to rotate. The rotation of the rotating disk can intermittently push the sliding column to turn on the switch of the air conditioner, so that the cold air is intermittently transported to the inside of the lower mold, which can further protect the upper mold and the lower mold and facilitate their forming work on the top of the test pile.

[0027] Further, in order to facilitate the heat dissipation work of the upper die 5 and the lower die 15 when stamping and forming the top of the test pile, and facilitate the improvement of their service lives, two groups of racks 16 are detachably connected in front of the pushing plate 8, a gear 17 is meshed in front of the racks 16, a rotating shaft 18 is fixedly connected inside the gear 17, the rotating shaft 18 is rotatably connected to the box body 1, and a pushing disc 19 and a rotating disc 23 are fixedly connected to the surface of the rotating shaft 18.

[0028] Further, in order to facilitate the intermittent addition of lubricating oil into the upper die 5 and then evenly flow to the lower die 15 and the top of the test pile to be formed, a piston rod 20 is arranged above the pushing disc 19, the piston rod 20 is slidably connected to a piston cylinder 21, the piston cylinder 21 communicates with the inside of the oil storage tank 2, the surface of the piston cylinder 21 is connected to the upper die 5 through a hose, and the upper die 5 is installed below the stamping cylinder 3.

[0029] Further, in order to more conveniently dissipate the heat generated during the operation of the upper die 5 and the lower die 15, the lower die 15 is installed below the upper die 5. The lower end of the rack 16 is detachably connected to the limit plate 22. A sliding column 24 is installed below the rotating disk 23. An air conditioner 6 is installed on the side of the box body 1. The lower end of the sliding column 24 is connected to the switch of the air conditioner 6.

[0030] Further, in order to facilitate the limitation of the main body of the test pile and facilitate the upper die 5 and the lower die 15 to perform forming work on it, an extrusion plate 25 is installed at the bottom of the pressure rod 13.

[0032] Further, the service life of local parts in the device can be improved, and the use cost can be reduced.

[0033] Further, in order to facilitate the device to perform top stamping and forming work on test piles with different diameters at the same time, the first push frame 10, the second push frame 11 and the extrusion block 12 are also made of high-strength materials. The triangular groove opened inside the limit groove 14 and the through groove opened inside the lower die 15 are both set in shapes with different widths.

[0034] The working principle and usage process of the present utility model: After the present utility model is installed, first add the lubricating oil to be used into the internal of the oil storage tank 2, and then insert a plurality of test piles with different diameters into the internal of the box body 1, so that the tops of the test piles are closely attached to the inner side surface of the moving plate 4. Then rotate the screw rod 7 to drive the push plate 8 to move downward inside the box body 1. When the push plate 8 moves, it will drive the first push frame 10 and the second push frame 11 to move downward through the connecting rod 9. The movement of the first push frame 10 and the second push frame 11 will drive a plurality of extrusion blocks 12 to move downward through the pin shafts. The downward movement of the extrusion blocks 12 will push the pressure rod 13 to move downward. The pressure rod 13 will drive the lower extrusion plate 25 to extrude and limit the test pile, so as to facilitate the subsequent top stamping and forming work on the test pile, with high working efficiency;

[0035] When the screw rod 7 drives the pushing plate 8 to move downward, the movement of the pushing plate 8 will drive two groups of racks 16 to move downward. The movement of the racks 16 will drive the gears 17 to rotate through meshing transmission. The gears 17 will drive the internal rotating shaft 18 to rotate. The rotation of the rotating shaft 18 can drive the push plate 19 to rotate. The rotation of the push plate 19 can intermittently push the piston rod 20 to slide inside the piston cylinder 21, so that the lubricating oil added to the inside of the storage oil tank 2 can be intermittently added to the inside of the upper die 5 through the hose on the surface of the piston cylinder 21, and then flow to the surface of the lower test pile through the liquid discharge hole opened below the upper die 5. This can avoid large friction when stamping and forming the top of the test pile, and at the same time reduce the heat generated during stamping and forming, and improve the service life of the upper die 5 and the lower die 15;

[0036] When the rotating shaft 18 rotates, it will also drive the rotating disk 23 to rotate. The rotation of the rotating disk 23 can intermittently push the sliding column 24 to move up and down. When the sliding column 24 moves downward, it can turn on the switch of the air conditioner 6, so that the cold air generated by the air conditioner 6 enters the inside of the lower die 15 through the pipeline, thereby further reducing the heat generated when the upper die 5 and the lower die 15 stamp and form the top of the test pile. After the preparation work is completed, the stamping cylinder 3 is started to drive the upper die 5 to move downward to perform the forming work on the top of the test pile. After stamping and forming, the moving plate 4 is opened at this time to take out the formed multiple test piles, so as to facilitate subsequent work, and the work efficiency is high;

[0037] Since a strong spring is arranged on the surface of the pressure rod 13, and the pushing plate 8 is rotationally connected to the first pushing frame 10 and the second pushing frame 11 through the connecting rod 9. When the first pushing frame 10, the second pushing frame 11 and the extrusion block 12 push the multiple pressure rods 13 to move downward, due to the different diameters of the multiple test piles, when the pressure rods 13 limit the test piles through the extrusion plate 25, it can avoid excessive extrusion of the test pile body with different diameters by the pressure rods 13 and cause damage to the test pile body. At the same time, when the upper die 5 and the lower die 15 stamp and form the top of the test pile, the limiting plate 22 can prevent the test pile from tilting when being extruded, and the forming stability is high.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
