Description

Technical Field

[0001] This utility model relates to the field of bracket technology, specifically to a pull-off valve bracket for unloading. Background Technology

[0002] A breakaway valve is an emergency disconnect device that prevents leaks caused by accidental pipeline rupture. It is applicable to ship-to-shore unloading, tank loading and unloading on highways and railways, and other fixed and mobile fluid storage devices, such as the connection between loading arms, fluid transfer arms and transport vehicles. When unloading breakaway valves, brackets are needed to place and lift them. Traditional brackets are mostly single-unit support blocks at the top, and their lifting method is relatively simple. During the unloading process, the lifting effect of a single-unit support block is poor, and tilting and displacement may occur. In order to improve this situation, a new unloading breakaway valve bracket is proposed.

[0003] For example, the unloading pull-off valve bracket disclosed in the authorization announcement number CN219327842U includes an upward push cylinder, a connecting rod is fixedly welded to the pushing end of the upward push cylinder, and a support assembly is welded to the top of the connecting rod; the support assembly includes a concave support block welded to the top of the connecting rod, and side support rods are connected to both sides of the concave support block, and a concave support plate is welded to one end of each side support rod; Although it achieves the upward movement of the connecting rod by setting up the support components and pushing the cylinder upward, the pull-off valve support plate can move upward and press against the lower surface of the pull-off valve. At the same time, the concave support block drives the two side support rods to move upward, and the edge pipe support plate can drive the rubber arc plate to fit against the lower surface of the pipe at both ends of the pull-off valve. This can ensure that the entire pull-off valve will not cause the pipe and valve to shake during use, and has higher stability. However, the existing brackets do not solve the problems that make it difficult to flexibly adjust and adapt to support breakaway valves of different specifications during use, and that it is not easy to flexibly adjust the placement height to avoid workers frequently bending over and causing back injuries, thus affecting the convenience and stability of unloading and placing breakaway valves. Utility Model Content

[0004] The purpose of this utility model is to provide a pull-off valve bracket for unloading, so as to solve the problems mentioned in the background art, which are not convenient to flexibly adjust and adapt to support pull-off valves of different specifications, are not conducive to flexibly adjusting the placement height to avoid workers frequently bending over and causing back injuries, and affect the convenience and stability of unloading and placing the pull-off valve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a unloading pull-off valve bracket, comprising a base and a bidirectional lead screw. The bidirectional lead screw is movably installed inside the base. Threaded sleeves are symmetrically installed on the surface of the bidirectional lead screw, and the threaded sleeves are threadedly connected to the bidirectional lead screw. A handle is provided on the side wall of the base on one side of the bidirectional lead screw, and the handle is connected to the bidirectional lead screw. A connecting rod is provided inside the base on one side of the bidirectional lead screw. A slider is symmetrically slidably installed on the surface of the connecting rod. A base frame is symmetrically installed above the base. Telescopic rods are symmetrically installed at the bottom ends of the base frames. A first sleeve is provided on the surface of each telescopic rod, and the telescopic rod is slidably connected to the first sleeve. A first locking pin is provided on the side wall of each first sleeve, and the first locking pin extends through the first sleeve to the surface of the telescopic rod, and the first locking pin is threadedly connected to the first sleeve. The first sleeve is connected to the threaded sleeve and the slider respectively. A top frame is provided on the side wall of each base frame, and a main support plate is symmetrically installed at the top of each top frame.

[0006] Preferably, each of the base frames has a second sleeve symmetrically and movably installed at its top, and each of the second sleeves has a sliding rod slidably installed inside.

[0007] Preferably, a second locking pin is provided on the side wall of the second sleeve, and the second locking pin extends through the second sleeve to the surface of the slide rod, and the second locking pin is threadedly connected to the second sleeve.

[0008] Preferably, both ends of the base frame are provided with adjusting arms, and the end of each adjusting arm near the base frame is provided with a hinge shaft, and the adjusting arm is movably connected to the base frame through the hinge shaft.

[0009] Preferably, each slide bar is provided with a connecting shaft at one end near the adjusting arm, and the slide bar is movably connected to the adjusting arm through the connecting shaft.

[0010] Preferably, each of the adjusting arms is provided with an adjusting block at the end away from the base frame, and each adjusting block is provided with a bolt and nut assembly at its bottom end, and the adjusting block is movably connected to the adjusting arm through the bolt and nut assembly.

[0011] Preferably, each of the adjustment blocks has a secondary support plate at its top, and each secondary support plate has a sliding groove inside, and each sliding groove has a limiting arc plate inside, and the limiting arc plate is slidably connected to the sliding groove.

[0012] Preferably, the top of each of the sub-support plates is provided with two sets of pin holes, and the end of each limiting arc plate away from the sub-support plate is provided with two sets of third locking pins, and the third locking pins are threadedly connected to the pin holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the bracket not only realizes flexible adjustment to adapt to lift pull-off valves of different specifications, but also facilitates flexible adjustment of the placement height to avoid frequent bending of workers and resulting in back injury, but also improves the convenience and stability of unloading and placing pull-off valves. Place the bracket in the unloading area of ​​the breakaway valve. First, measure the length of the breakaway valve. Turn the handle, which drives the double-acting screw to rotate. The double-acting screw drives two sets of threaded sleeves to move towards or opposite each other. The threaded sleeves drive the first sleeve to move towards or opposite each other. The first sleeve, through the telescopic rod, moves the base frame, top frame, and main support plate closer or further apart. Adjust the distance between the two sets of main support plates to accommodate breakaway valves of different lengths. To facilitate unloading the breakaway valve, first loosen the first locking pin to disengage the telescopic rod from the first sleeve. Move the base frame upward, which drives the telescopic rod to move inside the first sleeve. The base frame then drives the top frame and main support plate upward, adjusting the main support plate to a higher position. Tighten the first locking pin to fix the telescopic rod to the first sleeve, keeping the main support plate at the adjusted height. This reduces the number of times workers bend over, preventing back injuries during unloading. When the breakaway valve is straight... When the diameter is larger, if the auxiliary support plate is close to the main support plate, the two sets of breakaway valves will collide. Loosen the second locking pin to separate the slide rod from the second sleeve. Move the slide rod, and the slide rod will drive the adjusting arm to rotate around the hinge axis through the connecting shaft. The adjusting arm will drive the adjusting block and the auxiliary support plate to rotate, so that the auxiliary support plate is away from the main support plate. After adjusting to the working position, retighten the second locking pin to fix the slide rod to the second sleeve. Rotate the auxiliary support plate, and the auxiliary support plate will drive the adjusting block to rotate around the bolt and nut assembly, so that the opening of the auxiliary support plate faces upward. Then tighten the bolt and nut assembly to fix the adjusting block to the adjusting arm. Then place the breakaway valve with a larger diameter on the auxiliary support plate to avoid the collision of adjacent breakaway valves. This achieves flexible adjustment to support breakaway valves of different specifications, facilitates flexible adjustment of the placement height, avoids frequent bending of workers causing back injuries, and improves the convenience of unloading and placing the breakaway valve. When a larger diameter breakaway valve is placed on the sub-support plate, to prevent it from falling off, the third locking pin is pulled out. The third locking pin drives the limiting arc plate to slide in the groove, so that one end of the limiting arc plate contacts the sub-support plate, thereby forming a closed loop between the limiting arc plate and the sub-support plate. The third locking pin is then inserted into the pin hole and tightened to fix the limiting arc plate to the sub-support plate. This closed loop limits the breakaway valve, preventing it from falling off the sub-support plate and improving the stability of the breakaway valve during unloading and placement.

[0017] Please see Figure 1-5 This utility model provides an embodiment of a derailment valve bracket, comprising a base 1 and a bidirectional lead screw 17. The bidirectional lead screw 17 is movably installed inside the base 1. Threaded sleeves 2 are symmetrically installed on the surface of the bidirectional lead screw 17 and are threadedly connected to the bidirectional lead screw 17.

A connecting rod 18 is provided inside the base 1 on one side of the bidirectional lead screw 17. Sliding sliders 5 are symmetrically slidably installed on the surface of the connecting rod 18. Above the base 1... A base frame 4 is symmetrically arranged, and a telescopic rod 9 is symmetrically arranged at the bottom end of each base frame 4. A first sleeve 3 is provided on the surface of each telescopic rod 9, and the telescopic rod 9 is slidably connected to the first sleeve 3. A first locking pin 10 is provided on the side wall of each first sleeve 3, and the first locking pin 10 extends through the first sleeve 3 to the surface of the telescopic rod 9. The first locking pin 10 is threadedly connected to the first sleeve 3. The first sleeve 3 is connected to the threaded sleeve 2 and the slider 5 respectively. A top frame 7 is provided on the side wall of each base frame 4, and a main support plate 8 is symmetrically arranged on the top of each top frame 7. The top of the base frame 4 is symmetrically and movably equipped with a second sleeve 15, and the inside of the second sleeve 15 is slidably equipped with a slide rod 14; The second sleeve 15 is provided with a second locking pin 19 on its side wall. The second locking pin 19 extends through the second sleeve 15 to the surface of the slide rod 14. The second locking pin 19 is threadedly connected to the second sleeve 15. The base frame 4 is provided with an adjusting arm 12 at both ends. The adjusting arm 12 is provided with a hinge shaft 11 at the end near the base frame 4. The adjusting arm 12 is movably connected to the base frame 4 through the hinge shaft 11. Each slide rod 14 is provided with a connecting shaft 13 at one end near the adjusting arm 12, and the slide rod 14 is movably connected to the adjusting arm 12 through the connecting shaft 13.

The bracket is placed in the unloading area of ​​the breakaway valve. First, the length of the breakaway valve is measured. Then, handle 16 is turned, causing the double-acting screw 17 to rotate. With the double-acting screw 17 threadedly connected to the threaded sleeve 2, the double-acting screw 17 drives the two sets of threaded sleeves 2 to move towards or away from each other. With the sliding engagement of the slider 5 and the connecting rod 18, the threaded sleeves 2 drive the first sleeve 3 to move towards or away from each other. The first sleeve 3, through the telescopic rod 9, drives the base frame 4, top frame 7, and main support plate 8 to move closer or further apart, adjusting the distance between the two sets of main support plates 8, thereby... To accommodate breakaway valves of varying lengths and facilitate unloading for workers, first loosen the first locking pin 10 to disengage the telescopic rod 9 from the first sleeve 3. Then, move the base frame 4 upwards, causing the telescopic rod 9 to move within the first sleeve 3. The base frame 4 then moves the top frame 7 and the main support plate 8 upwards, adjusting the main support plate 8 to a higher position. Finally, tighten the first locking pin 10 to secure the telescopic rod 9 to the first sleeve 3, maintaining the main support plate 8 at the adjusted height. This reduces the number of times workers need to bend over, thus preventing injuries during unloading. When the diameter of the breakaway valve is relatively large, if the auxiliary support plate 22 is close to the main support plate 8, the two sets of breakaway valves will collide. Loosen the second locking pin 19 to separate the slide rod 14 from the second sleeve 15. Move the slide rod 14, which will drive the adjusting arm 12 to rotate around the hinge shaft 11 via the connecting shaft 13. The adjusting arm 12 will then drive the adjusting block 21 and the auxiliary support plate 22 to rotate, moving the auxiliary support plate 22 away from the main support plate 8. After adjusting to the working position, retighten the second locking pin 19 to fix the slide rod 14 to the second sleeve 15. Rotate the auxiliary support plate 22 to ensure proper connection. The auxiliary support plate 22 drives the adjusting block 21 to rotate around the bolt and nut assembly 20 as the axis, so that the opening of the auxiliary support plate 22 faces upward. Then, tighten the bolt and nut assembly 20 to fix the adjusting block 21 to the adjusting arm 12. Then, place the larger diameter breakaway valve on the auxiliary support plate 22 to avoid the collision of adjacent breakaway valves. This realizes flexible adjustment to adapt to and lift breakaway valves of different specifications, facilitates flexible adjustment of the placement height, avoids frequent bending of workers causing back injuries, and improves the convenience of unloading and placing breakaway valves. Each adjustment block 21 has a secondary support plate 22 at its top, and each secondary support plate 22 has a sliding groove 24 inside. Each sliding groove 24 has a limiting arc plate 23 inside, and the limiting arc plate 23 is slidably connected to the sliding groove 24. The top of the auxiliary support plate 22 is provided with two sets of pin holes 6, and the end of the limiting arc plate 23 away from the auxiliary support plate 22 is provided with two sets of third locking pins 25, and the third locking pins 25 are threadedly connected to the pin holes 6. When a larger diameter breakaway valve is placed on the sub-support plate 22, to prevent it from falling off, the third locking pin 25 is pulled out. The third locking pin 25 drives the limiting arc plate 23 to slide in the slide groove 24, so that one end of the limiting arc plate 23 contacts the sub-support plate 22, thereby forming a closed ring between the limiting arc plate 23 and the sub-support plate 22. The third locking pin 25 is inserted into the pin hole 6 and tightened to fix the limiting arc plate 23 to the sub-support plate 22. The closed ring limits the breakaway valve, preventing it from falling off the sub-support plate 22, which can improve the stability of the breakaway valve when unloading and placing it.

[0018] Working principle: The bracket is placed in the unloading area of ​​the breakaway valve. First, the length of the breakaway valve is measured. The handle 16 is rotated, causing the double-acting screw 17 to rotate. With the double-acting screw 17 threadedly connected to the threaded sleeve 2, the double-acting screw 17 drives the two sets of threaded sleeves 2 to move towards or opposite each other. With the sliding engagement of the slider 5 and the connecting rod 18, the threaded sleeves 2 drive the first sleeve 3 to move towards or opposite each other. The first sleeve 3, through the telescopic rod 9, drives the base frame 4, top frame 7, and main support plate 8 to move closer or further apart, adjusting the distance between the two sets of main support plates 8 to accommodate breakaway valves of different lengths. This facilitates better handling of the breakaway valve by workers. For unloading, first loosen the first locking pin 10 to disengage the telescopic rod 9 from the first sleeve 3. Move the base frame 4 upwards, causing the telescopic rod 9 to move within the first sleeve 3. The base frame 4 then moves the top frame 7 and the main support plate 8 upwards, adjusting the main support plate 8 to a higher position. Tighten the first locking pin 10 to fix the telescopic rod 9 to the first sleeve 3, maintaining the main support plate 8 at the adjusted height. This reduces the number of times workers bend over, preventing back injuries during unloading. When the diameter of the breakaway valve is large, if the auxiliary support plate 22 is close to the main support plate 8, the two sets of breakaway valves will collide. Loosen the second locking pin 19 to allow the sliding rod 1... 4. Separate from the second sleeve 15, move the slide rod 14, which drives the adjusting arm 12 to rotate around the hinge shaft 11 via the connecting shaft 13. The adjusting arm 12 drives the adjusting block 21 and the auxiliary support plate 22 to rotate, so that the auxiliary support plate 22 moves away from the main support plate 8. After adjusting to the working position, retighten the second locking pin 19 to fix the slide rod 14 to the second sleeve 15. Rotate the auxiliary support plate 22, which drives the adjusting block 21 to rotate around the bolt and nut assembly 20, so that the opening of the auxiliary support plate 22 faces upward. Then tighten the bolt and nut assembly 20 to fix the adjusting block 21 to the adjusting arm 12. Then, move the thicker diameter... Placing the breakaway valve on the auxiliary support plate 22 avoids collisions between adjacent breakaway valves. When a breakaway valve with a larger diameter is placed on the auxiliary support plate 22, to prevent it from falling off, the third locking pin 25 is pulled out. The third locking pin 25 drives the limiting arc plate 23 to slide in the slide groove 24, so that one end of the limiting arc plate 23 contacts the auxiliary support plate 22, thereby forming a closed ring between the limiting arc plate 23 and the auxiliary support plate 22. The third locking pin 25 is inserted into the pin hole 6 and tightened to fix the limiting arc plate 23 to the auxiliary support plate 22. The closed ring limits the breakaway valve and prevents it from falling off the auxiliary support plate 22.
