[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 This utility model provides a quick disassembly device for a petrochemical terminal oil transport arm, comprising: a support plate 9, an upper limit frame 4 fixedly connected to the lower surface of the support plate 9, two upper sliding blocks 21 slidably connected to the inner surface of the upper limit frame 4, a telescopic rail 10 fixedly connected to the lower surface of the two upper sliding blocks 21, two lower sliding blocks 23 fixedly connected to the lower end of the telescopic rail 10, and a lower limit frame 5, with the two lower sliding blocks 23 slidably connected to the inner surface of the lower limit frame 5.

[0022] Specifically: two upper sliding blocks 21 are slidably connected within the upper limit frame 4, and two lower sliding blocks 23 are slidably connected within the lower limit frame 5. The upper sliding blocks 21 and lower sliding blocks 23 are connected by a telescopic bar 10. The telescopic bar 10 can fold and extend when the lower sliding blocks 23 move.

[0023] The lower limit frame 5 is fixedly connected to the base plate 11. The inner surface of the upper limit frame 4 is fixedly connected to two slide rods 22. Two upper sliding blocks 21 are slidably connected to the outer wall of the two slide rods 22. The inner surface of the lower limit frame 5 is rotatably connected to a two-way lead screw 24. The two-way lead screw 24 is threadedly connected to the two lower sliding blocks 23. The side surface of the lower limit frame 5 is fixedly connected to a motor 3 17. The two-way lead screw 24 is driven by the motor 3 17.

[0024] Specifically: A bidirectional lead screw 24 is rotatably connected inside the lower limit frame 5. It is threadedly connected to two lower sliding blocks 23 and driven to rotate by a motor 3 17. When the motor 3 17 starts, the bidirectional lead screw 24 rotates. Due to the threaded engagement between the bidirectional lead screw 24 and the lower sliding blocks 23, the two lower sliding blocks 23 move towards or away from each other on the inner surface of the lower limit frame 5. When the two lower sliding blocks 23 move away from each other, the telescopic bar 10 is compressed and folded, causing the upper sliding block 21 to move away from each other within the upper limit frame 4, thereby causing the bearing plate 9 and frame 8 and other components to descend as a whole. Conversely, when the two lower sliding blocks 23 move towards each other, the telescopic bar 10 extends, causing the upper sliding block 21 to move towards each other within the upper limit frame 4, causing the bearing plate 9 and frame 8 and other components to rise as a whole. This achieves vertical height adjustment of the device to meet the disassembly requirements of oil delivery arms at different heights.

[0025] A frame 8 is fixedly connected to the upper surface of the bearing plate 9. Two movable plates 6 are slidably connected to the inner surface of the frame 8. A bidirectional lead screw 20 is rotatably connected to the inner surface of the frame 8. A motor 16 is fixedly connected to the side surface of the frame 8. The bidirectional lead screw 20 is driven by the motor 16. Both ends of the bidirectional lead screw 20 are threadedly connected to the two movable plates 6 respectively.

[0026] Specifically: In use, the oil delivery arm is placed inside the frame 8, between two movable plates 6. A bidirectional lead screw 20 is rotatably connected inside the frame 8. It is threadedly connected to the two movable plates 6 and driven to rotate by a motor 16. When the motor 16 starts, the bidirectional lead screw 20 rotates. Due to the threaded engagement between the bidirectional lead screw 20 and the movable plates 6, the two movable plates 6 move towards or away from each other on the inner surface of the frame 8. When they move towards each other, they drive multiple clamping plates 7 to move synchronously, thereby clamping and fixing the oil delivery arm in the middle. After it is fixed, the oil delivery arm can be disassembled.

[0027] The movable plate 6 is provided with a main slide groove 19 and two secondary slide grooves 18, which are located on the upper and lower sides of the main slide groove 19. A main slider 13 is slidably connected to the inner surface of the main slide groove 19, and a secondary slider 12 is slidably connected to the inner surface of the secondary slide grooves 18. A main connecting block 27 is fixedly connected to the rear surface of the main slider 13, and a secondary connecting block 25 is fixedly connected to the rear surface of the secondary slider 12. Pull rods 26 are fixedly connected to the two opposite side surfaces of the main connecting block 27, and the two pull rods 26 respectively pass through... The two connecting blocks 25 are slidably connected inside each other. The inner surface of the main slide groove 19 is rotatably connected to a screw 15. The side surface of the moving plate 6 is fixedly connected to a motor 14. The screw 15 is driven by the motor 14. The screw 15 is threadedly connected to the main slider 13. The front surfaces of the main slider 13 and the sliding block 12 are both fixedly connected to a connecting plate 1. The side surface of the connecting plate 1 is fixedly connected to a spring 3. The side surface of the connecting plate 1 is fixedly connected to a damper 2. The other end of the spring 3 and the damper 2 is fixedly connected to a clamping plate 7.

[0028] Specifically: On the movable plate 6, a main slider 13 is slidably connected in the main slide groove 19, and a secondary slider 12 is slidably connected in the secondary slide groove 18. A main connecting block 27 is fixedly connected to the rear surface of the main slider 13, and a secondary connecting block 25 is fixedly connected to the rear surface of the secondary slider 12. A pull rod 26 is fixedly connected to the two opposite surfaces of the main connecting block 27, and the pull rod 26 is slidably connected inside the secondary connecting block 25. A screw 15 is rotatably connected in the main slide groove 19. The screw 15 is driven by a motor 14 and is threadedly connected to the main slider 13. When the motor 14 starts, the screw 15 rotates, causing the main slider 13 to move within the main slide groove 19. Due to the connection relationship of the pull rod 26, the movement of the main slider 13 will drive the slave slider 12 to move in the slave groove 18 through the pull rod 26, thereby realizing the synchronous movement of the main slider 13 and the slave slider 12. The front surfaces of the main slider 13 and the slave slider 12 are fixedly connected to the connecting plate 1. The side surface of the connecting plate 1 is fixedly connected to the spring 3 and the damper 2. The other end of the spring 3 and the damper 2 is fixedly connected to the clamping plate 7. As the main slider 13 and the slave slider 12 move, the connecting plate 1 will move, which in turn will move the clamping plate 7, thereby realizing the adjustment of the position of the clamping plate 7, and finally enabling the clamping plate 7 to adapt to oil delivery arms of different sizes and effectively clamp them.

[0029] Working principle: During use, the oil delivery arm is placed inside the frame 8, between two movable plates 6. A double-acting screw 20 is rotatably connected inside the frame 8, and it is threaded through the two movable plates 6. It is driven to rotate by a motor 16. When the motor 16 starts, the double-acting screw 20 rotates. Due to the threaded engagement between the double-acting screw 20 and the movable plates 6, the two movable plates 6 move towards or away from each other on the inner surface of the frame 8. When they move towards each other, they drive multiple clamping plates 7 to move synchronously, thereby clamping and fixing the middle oil delivery arm. After it is fixed, the oil delivery arm can be disassembled.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
