Description

Technical Field

[0001] This utility model relates to an oil tank pouring support device, and belongs to the technical field of oil tank auxiliary devices. Background Technology

[0002] Crude oil is mostly stored in oil tanks. Due to the weight of the tanks, it is inconvenient to pour the crude oil during use. If an outlet is opened at the bottom of the tank, the tank will not be reusable. Existing oil tank pouring equipment generally uses clamps to hold the tank and pour the crude oil. However, during the pouring process, the tank is only supported by the clamps, resulting in poor protection of the tank and reducing the service life of the clamps. Summary of the Invention

[0003] The purpose of this invention is to design a support device that can assist in pouring oil from an oil tank.

[0004] This utility model includes a base, which includes a clamping mechanism and a first lifting rod and a second lifting rod respectively arranged on the front and rear sides of the clamping mechanism. The clamping mechanism includes a base and two opposing left and right columns fixed on the base. Electric push rods are arranged on the inner side of the upper part of the left and right columns. The inner end of each electric push rod is fixedly connected to an arc-shaped clamping plate. The inner surface of each arc-shaped clamping plate is fixed with an anti-slip pad. The two electric push rods are connected to their adjacent columns through bearings. One of the electric push rods is fixed with a driven gear, which meshes with a driving gear driven by a hydraulic motor. The first lifting rod and the second lifting rod are respectively connected to the first lifting mechanism and the second lifting mechanism.

[0005] Furthermore, the first or second lifting mechanism includes a left support column and a right support column respectively located on the base and corresponding to the positions of the left and right columns. The left and right support columns are respectively equipped with longitudinal lead screws connected to their lifting motors. Each longitudinal lead screw has a first nut that cooperates with it. The two ends of the first or second lifting rod are respectively fixedly connected to the first nuts on the corresponding left and right support columns.

[0006] Furthermore, a reinforcing block is fixedly connected to the inner side of the bottom of the left and right columns, and the upper surface of the reinforcing block is a slope.

[0007] Furthermore, a placement seat is provided between the left and right columns, below each arc-shaped clamping plate. The placement seat includes a bottom box with an open upper end, and a top plate is provided above the bottom box. At least one tank lifting mechanism is provided between the bottom surface of the bottom box and the top plate. Each tank lifting mechanism includes a transverse lead screw mounted on the side wall of the upper part of the bottom box via bearings. The transverse lead screw is connected to its drive motor. There are two second nuts that cooperate with the transverse lead screw. Each second nut is mounted with an upper connecting rod and a lower connecting rod via a shaft. The lower ends of the two lower connecting rods are connected to a lower positioning block fixed on the bottom surface of the bottom box via a shaft. The upper ends of the two upper connecting rods are connected to an upper positioning block via a shaft. The upper positioning block is fixed on the lower surface of the top plate.

[0008] This invention features first and second lifting mechanisms on both sides of the clamping mechanism. A lifting motor controls the up-and-down movement of the lifting rods. During oil pouring, the lifting rods on both sides support both ends of the oil tank, distributing the weight of the arc-shaped clamping plate and providing auxiliary support, thus improving the protection of the oil tank. Furthermore, by adjusting the position of the lifting rods on both sides, the oil pouring area can be accessed from both sides of the clamping mechanism, increasing the working range and improving the flexibility of the device.

The outer ends of each electric push rod 5 are rotatably connected to the left and right columns respectively through bearings. An arc-shaped clamping plate 6 is provided at the inner push rod of each electric push rod 5. The arc-shaped clamping plate 6 is welded and fixed to the push rod of the electric push rod 5. In use, the arc-shaped clamping plate 6 can be controlled by the electric push rod 5 to clamp the oil tank. Anti-slip pads 7 are fixedly installed on the inner surface of each arc-shaped clamping plate 6, which can play an anti-slip role when clamping the oil tank. A hydraulic pump 8 is installed on the outer side of the right column 4. The shaft of the hydraulic pump 8 passes through the right column 4, and a drive gear 9 is fixedly installed on the inner side of the right column 4. A driven gear 10 is installed on the outer shell of the electric push rod 5 inside the right column 4. The driven gear is fixedly connected to the outer shell of the electric push rod 5 and meshes with the drive gear 9. In use, starting the hydraulic pump 8 can control the rotation of the electric push rod on the right column 4. In this embodiment, a reinforcing block 11 is installed on the inner side of the bottom of the left and right columns. The reinforcing block 11 is triangular, with an inclined upper surface and the remaining surfaces fixedly connected to the left and right columns and the base 2. It can provide auxiliary support for the left and right columns and enhance the stability of the two columns.

[0019] A first lifting mechanism 12 is provided in front of the clamping mechanism 1. The first lifting mechanism 12 includes a left support column 14 and a right support column 15 opposite to it. Both support columns are fixedly installed on the base 2. The positions of the left and right support columns correspond to those of the left and right columns. Each support column is equipped with a lifting motor 16 at its upper end. The shaft of each lifting motor 16 is set downwards, and a longitudinal lead screw 17 is installed at the shaft. The lower end of the longitudinal lead screw 17 is rotatably connected to the inner wall of the support column through a bearing. In use, starting the lifting motor 16 can control the rotation of the longitudinal lead screw 17. A matching first nut 18 is screwed onto the outer circumference of each longitudinal lead screw 17. When the longitudinal lead screw 17 rotates, it can control the first nut 18 to move up and down. A first lifting rod 13 is provided inside the left support column 14 and the right support column 15. The left and right ends of the first lifting rod 13 are fixedly connected to the first nuts of the two support columns. In use, controlling the lifting motor can make the first lifting rod 13 move up and down.

[0020] A second lifting mechanism 19 is provided behind the clamping mechanism 1, and a second lifting rod 20 is provided inside the second lifting mechanism 19. The connection and transmission relationship of the second lifting mechanism 19 are the same as those of the first lifting mechanism 12, and will not be described in detail here.

[0021] A placement seat 21 is provided between the left column 3 and the right column 4, and the placement seat 21 is located below each arc-shaped clamping plate 6. The placement seat 21 includes a base box 22 with an opening at the top and a top plate 23 above it. A tank lifting mechanism is provided between the top plate 23 and the base box 22. In this embodiment, two tank lifting mechanisms are provided. Each tank lifting mechanism includes a transverse lead screw 24. The front end of each transverse lead screw 24 is rotatably connected to the front side wall of the upper part of the base box 22 through a bearing, and the rear end passes through the base box 22 and is connected to the shaft of the drive motor 31. The drive motor 31 is fixedly installed on the rear surface of the base box 22. Starting the drive motor 31 can control the rotation of the transverse lead screw 24. In this embodiment, the threads of the front and rear parts of each transverse lead screw 24 have opposite directions, and two matching second nuts 25 are screwed onto the front and rear sides. Two upper connecting rods 26 are arranged above the transverse lead screw 24, and the upper ends of the two upper connecting rods 26 are rotatably connected to the upper positioning block 28 via connecting shafts. Two lower connecting rods 27 are arranged below the transverse lead screw 24, and the lower ends of the two lower connecting rods 27 are rotatably connected to the lower positioning block 29 via connecting shafts. The upper positioning block 28 is fixedly connected to the lower surface of the top plate 23, and the lower surface of the lower positioning block 29 is fixedly connected to the bottom surface of the base box 22. The lower ends of the two upper connecting rods 26 and the upper ends of the two lower connecting rods 27 are rotatably connected via the extension shaft of the second lead screw nut 25, which allows the upper connecting rods 26 and lower connecting rods 27 to move with the second lead screw nut 25. In use, after starting the drive motor 31, the top plate 23 can be moved up and down by the relative movement of the front and rear second lead screw nuts 25. A protective pad 30 is provided on the upper end of the top plate 23, which can play a role in shock absorption and protection when placing oil tanks.

[0022] In this embodiment, firstly, the drive motors 31 are controlled to move the top plate 23 upwards to its limit position. Then, the oil tank is hoisted onto the placement seat 21, and the electric actuators 5 are activated to clamp and fix the oil tank. In this embodiment, the front side of the device is the pouring area. The first lifting rod 13 needs to be moved to its upper limit position, and the second lifting rod 20 to its lower limit position. After completion, the drive motors 31 are controlled to move the top plate 23 downwards, leaving room for the oil tank to rotate. Then, the pouring motor 8 is activated, controlling the electric actuators 5 and the oil tank to rotate forward. During rotation, when the oil tank contacts the first lifting rod 13, the lifting motor 16 of the first lifting mechanism 12 is activated, causing the first lifting rod 13 to move downwards with the rotation of the oil tank, sharing the load of the arc-shaped clamping plate 6 during the pouring process. When the bottom of the oil tank rotates above the second lifting rod 20, the lifting motor of the second lifting mechanism 19 is activated, causing the second lifting rod 20 to release the oil tank and move upwards with the rotation of the oil tank, sharing the load of the arc-shaped clamping plate 6. After the oil is poured out, the reverse oil pouring motor 8 resets the oil tank, and at the same time, the first lifting rod 13 and the second lifting rod 20 are reset as the oil tank rotates. After the oil tank is reset, the drive motor 31 is controlled to move the top plate 23 upward to support the oil tank, and then each electric push rod 5 is reset to replace the oil tank.
