Description

Technical Field

[0001] This utility model relates to the field of pipeline clamp disassembly technology, specifically a hydraulic support pipeline clamp removal tool. Background Technology

[0002] Hydraulic support pipe clamps are special accessories used to fix the pipe connections of hydraulic supports. Their main function is to prevent loosening, falling off, or leakage by tightening the pipe joints, thereby ensuring the stable operation and safety of the hydraulic system.

[0003] To prevent the pipe clamps from loosening and falling off, it is necessary to ensure that the U-shaped clamps are fully inserted into the connector pin holes and locked with the U-shaped pins during installation. However, when the hydraulic lines need to be moved, the pipe clamps need to be removed, and the tightened pipe clamps are difficult to remove. Therefore, when removing the pipe clamps, due to the limited operating space, it is difficult for workers to use large tools, and they can usually only use a screwdriver to pry them off.

[0004] However, in actual operation, due to the small operating space, the firm fixing of the pipe clamps, the low strength of the screwdriver, and the lack of a fulcrum to pry open during the process, the operation is very difficult, which can easily cause the screwdriver to bend and break, and can easily cause workers to be cut or crushed by the screwdriver and pipe clamps.

[0005] Therefore, a hydraulic support pipe clamp removal tool is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The hydraulic support pipeline clamp removal tool of this utility model includes a pair of sleeve rods; an extension rod is slidably installed between the pair of sleeve rods; a flat shovel head is bolted to the end of one sleeve rod; a hammer seat is bolted to the end of the other sleeve rod; and a pointed hammer head is bolted to the bottom of the hammer seat.

[0008] Preferably, the flat shovel head has a V-shaped groove in the middle of the end away from the sleeve.

[0009] Preferably, the top surfaces of both sides of the card slot are provided with inclined sliding platforms; the top surfaces of the sliding platforms are uniformly fixed with multiple anti-slip protrusions.

[0010] Preferably, V-shaped cutters are fixedly connected to the middle of both sides of the slot.

[0011] Preferably, the outer ring of the sleeve is provided with multiple sliding grooves; a ring hammer is slidably installed on the outer ring of one of the sleeves near the flat shovel head, and the ring hammer is locked to the sleeve by screws.

[0012] Preferably, a fan-shaped groove is formed on the top of the side of the hammer base away from the sleeve rod; a rotating arm is rotatably installed at the circular part of the fan-shaped groove; a fulcrum column capable of telescopic movement is installed at the end of the rotating arm away from the hammer base; and a pressure plate is provided between the fulcrum column and the hammer base.

[0013] Preferably, arc-shaped grooves are provided on both sides of the fan-shaped groove; and protrusions that slide in cooperation with the arc-shaped grooves are fixed on both sides of the rotating arm.

[0014] The advantages of this utility model are: 1. The hydraulic support pipe clamp removal tool of this utility model is configured with a sleeve rod, an extension rod, a flat shovel head, a hammer seat, a pointed hammer head, a retaining ring, and an external thread block. By adjusting the length of the lever arm formed by the sleeve rod and the extension rod, and by selecting either the flat shovel head or the pointed hammer head, it is convenient for workers to remove pipe clamps in different states in different operating spaces, making the operation easier for workers and reducing the difficulty of removal work and the probability of injury.

[0015] 2. The hydraulic support pipeline clamp removal tool of this utility model is configured with a fan-shaped groove, a rotating arm, a fulcrum column, and a pressure plate. Rotating the fulcrum column causes its screw to move along the screw hole of the rotating arm, causing the fulcrum column to press against the pressure plate. The pressure plate then presses against the outer wall of the hammer seat, thereby fixing and locking the fulcrum column. The fulcrum column can be fixed to the bottom outer side of the fan-shaped groove, i.e., the fulcrum column and the sleeve rod are on the same axis. The fulcrum column can also be fixed to the top outer side of the fan-shaped groove, i.e., the fulcrum column and the pointed hammer head are on the same axis. By adjusting the position of the fulcrum column, the position of the fulcrum can be controlled and adjusted, thus facilitating clamp removal work in different situations and expanding the applicability of the removal work.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] like Figures 1 to 3 As shown, a hydraulic support pipe clamp removal tool includes a pair of sleeve rods 1; an extension rod 2 is slidably installed between the pair of sleeve rods 1; a flat shovel head 3 is bolted to the end of one sleeve rod 1; a hammer seat 4 is bolted to the end of the other sleeve rod 1; and a pointed hammer head 5 is bolted to the bottom of the hammer seat 4. Specifically, the two sleeve rods 1 have an inner cavity at their close ends, and the extension rod 2 is located in the inner cavity between the two sleeve rods 1; a retaining ring 6 is fixedly installed at the close ends of the two sleeve rods 1 by screws; the outer diameter of the retaining ring 6 is the same as the outer diameter of the sleeve rod 1, and the inner diameter of the retaining ring 6 is smaller than the inner diameter of the sleeve rod 1 and larger than the outer diameter of the extension rod 2; both ends of the extension rod 2 are bolted with cylindrical external threaded blocks 7; both ends of the inner cavity of the sleeve rod 1 are provided with internal threads that match the external threaded blocks 7; Two sleeve rods 1 are fixed to a regular polygonal mounting block at their far ends. The flat shovel head 3 and the hammer seat 4 are both provided with grooves that match the mounting blocks at their ends near the sleeve rods 1, and are fixed and locked by multiple screws. The end of the flat shovel head 3 closest to the sleeve rod 1 is cylindrical, and its diameter is the same as that of the sleeve rod 1; the end of the flat shovel head 3 furthest from the sleeve rod 1 is flat; the end of the flat shovel head 3 furthest from the sleeve rod 1 is curved upward. The hammer base 4 has a circular cylindrical structure, and the bottom of the hammer base 4 is provided with a insertion groove that matches the top of the pointed hammer head 5; the insertion groove of the hammer base 4 is provided with a through hole at the position corresponding to the pointed hammer head 5, and a double-headed bolt is provided inside the through hole. The top of the pointed hammer head 5 has a square columnar structure, and the bottom has a pointed structure; When using this device, depending on the location of the pipe clamp, choose to use either the flat shovel head 3 or the pointed hammer head 5 to remove the clamp. Insert the flat shovel head 3 into the gap between the clamp and the pipe, and using the end of the flat shovel head 3 near the sleeve 1 as a fulcrum, turn the sleeve 1 to rotate the flat shovel head 3, thus prying the clamp outward. Alternatively, insert the tip of the pointed hammer head 5 into the gap between the clamp and the pipe, and using the hammer base 4 as a fulcrum, turn the sleeve 1 to rotate the hammer base 4 and the pointed hammer head 5, thus prying the clamp outward. This makes it easier for workers to remove the clamp in confined spaces, improving the convenience of removal. Meanwhile, based on the actual operating conditions, the size of the operating space, and the required force, the staff adjusted the combined length of the sleeve rod 1 and the extension rod 2 to adjust the lever arm length when prying the clamp. When the extension rod 2 is completely inside the inner cavity of the two sleeve rods 1, the external threaded blocks 7 at both ends of the extension rod 2 are fixed with the threaded engagement at the bottom of the inner cavity of the sleeve rod 1. At this time, the length of the removal tool is the shortest and the lever arm length is the shortest. Although the force required for the removal operation is the greatest, it is convenient for the operator to operate in a confined space. Rotating one sleeve rod 1 causes the thread at the bottom of its inner cavity to rotate relative to the external threaded block 7 of the extension rod 2 located within the inner cavity of the sleeve rod 1. This loosens the fixation between the external threaded block 7 and the sleeve rod 1, allowing the external threaded block 7 to slide inside the sleeve rod 1. Pulling the extension rod 2 to slide it outward from the sleeve rod 1 causes the external threaded block 7 to contact the thread at the opening of the inner cavity of the sleeve rod 1. Rotating the sleeve rod 1 then fixes the external threaded block 7 at the opening of the inner cavity of the sleeve rod 1. In this way, the length of the two sleeve rods 1 is extended by half the length of the extension rod 2, thereby extending the length of the removal tool and the lever arm. At this point, the force required for removal is reduced, but the space required for operation is relatively increased. Similarly, the other half of the extension rod 2 is also moved out from the other sleeve rod 1 and fixed by the external threaded block 7 at this end and the threaded engagement at the inner cavity opening of the sleeve rod 1; that is, the length of the entire extension rod 2 is extended between the two sleeve rods 1; at this time, the length of the tool is the largest, the lever arm is the largest, the force required for the tool removal operation is the smallest, but the space required for the operation is also the largest. By adjusting the length of the lever arm composed of the sleeve rod 1 and the extension rod 2, and by selecting the flat shovel head 3 or the pointed hammer head 5, it is easier for workers to remove pipe clamps in different states in different operating spaces. This makes the operation easier for workers and reduces the difficulty of the removal work and the probability of injury.

[0021] In some embodiments, such as Figures 4 to 5 As shown, a V-shaped groove 8 is provided in the middle of the end of the flat shovel head 3 away from the sleeve rod 1; Specifically, during the installation of pipe clamps, nails are used to fix the pipe clamps to the wall or brackets and other supporting structures. When removing the clamps, the nails need to be removed. By inserting the flat shovel head 3 under the outer edge of the nail, the slot 8 of the flat shovel head 3 is engaged with both sides of the nail shaft. Using the end of the flat shovel head 3 near the sleeve rod 1 as a fulcrum, the sleeve rod 1 is turned to rotate the flat shovel head 3 and pull out the nail. This makes it easier for workers to pull out the nail and remove the entire pipe clamp.

[0022] Furthermore, such as Figures 4 to 5 As shown, inclined slides 9 are provided on the top surfaces of both sides of the slot 8; multiple anti-slip protrusions are uniformly fixed to the top surface of the slides 9. Specifically, the slide table 9 is opened along the top surfaces of both sides of the slot 8, and the depth of the end of the slide table 9 away from the sleeve rod 1 is greater than the depth of the end closer to the sleeve rod 1; When the slot 8 of the flat shovel head 3 is engaged with both sides of the nail shaft, the two sides of the nail flange slide against the two side slides 9. The two side slides 9 lift up the nail flange, and the anti-slip strips prevent the nail flange from sliding between the slides 9, thereby fixing the nail in the slot 8 and improving the efficiency of nail removal.

[0023] Furthermore, such as Figures 4 to 6 As shown, V-shaped cutters 10 are fixedly connected to the middle of both sides of the slot 8; Specifically, the cutter 10 has a V-shaped structure that matches the shape of the slot 8, and the length of the two sides of the cutter 10 is less than the length of the two sides of the slot 8; the cutting edge of the cutter 10 is located on the inside of the V-shape. Some pipe clamps are tied with wire, and the wire needs to be cut when removing them. At this time, the slot 8 of the flat shovel head 3 is inserted into the outside of the wire, so that the wire is inserted into the cutter 10. Then, the sleeve rod 1 is repeatedly turned to make the flat shovel head 3 swing, so that the cutter 10 swings to cut the wire, thus achieving the purpose of cutting the wire, which makes it easier for the staff to remove it.

[0024] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the outer ring of the sleeve rod 1 is provided with multiple sliding grooves 11; a ring hammer 12 is slidably installed on the outer ring of one of the sleeve rods 1 near the flat shovel head 3, and the ring hammer 12 is locked to the sleeve rod 1 by screws. Specifically, multiple grooves 11 are opened parallel to each other along the axis of the sleeve rod 1; the ring hammer 12 consists of a ring-shaped sliding ring and a square hammer. The inner ring of the sliding ring is provided with a slider that slides with the groove 11. The two sides of the sliding ring are locked to the sleeve rod 1 by multiple screws. The square hammer is fixed to the bottom of the sliding ring; the bottom of the square hammer at the bottom of the ring hammer is provided with an arc-shaped chamfer on the side near the flat shovel head 3. The ring hammer 12 makes it easy for workers to use the square hammer at the bottom of the ring hammer 12 to hammer, which makes it easier for workers to install nails and other workpieces that need to be hammered. Using the ring hammer 12 as a fulcrum, the ring hammer 12 slides along the slide groove 11 to control the distance between the ring hammer 12 and the flat shovel head 3, thereby controlling the position of the fulcrum and making it easier for the staff to operate the flat shovel head 3 to remove the pipe clamps. By setting the square hammer at the bottom of the ring hammer 12 with an arc chamfer, it is easier for the ring hammer 12 to rotate, which in turn makes it easier to drive the flat shovel head 3 to rotate, thus improving the effect of the flat shovel head 3 in removing pipe clamps.

[0025] In some implementations, such as Figure 1 , Figure 2 , Figures 8 to 12 As shown, a fan-shaped groove 13 is provided on the top of the side of the hammer base 4 away from the sleeve rod 1; a rotating arm 14 is rotatably installed at the circular part of the fan-shaped groove 13; a telescopic fulcrum 15 is installed at the end of the rotating arm 14 away from the hammer base 4; a pressure plate 16 is provided between the fulcrum 15 and the hammer base 4. Specifically, a circular hole is provided at the center of the sector groove 13, and one end of the rotating arm 14 near the center of the sector groove 13 is rotatably connected to the circular hole through a rotating shaft. A screw hole is provided at the end of the rotating arm 14 away from the hammer seat 4. The fulcrum column 15 is composed of a round-headed column and a screw rod. The screw rod of the fulcrum column 15 is threadedly engaged with the screw hole of the rotating arm 14. A through hole is provided in the middle of the pressure plate 16, which is sleeved on the outer ring of the screw rod of the fulcrum column 15. Rotating the fulcrum column 15 causes the screw of the fulcrum column 15 to move along the screw hole of the rotating arm 14, causing the fulcrum column 15 to press against the pressure plate 16, and the pressure plate 16 to press against the outer wall of the hammer seat 4, thereby fixing and locking the fulcrum column 15; the fulcrum column 15 can be fixed on the bottom outer side of the sector groove 13, that is, the fulcrum column 15 and the sleeve rod 1 are on the same axis; the fulcrum column 15 can be fixed on the top outer side of the sector groove 13, that is, the fulcrum column 15 and the pointed hammer head 5 are on the same axis; When the fulcrum 15 is located on the top outside of the fan-shaped groove 13, it is suitable for situations where the gap between the pipe clamp and the pipe is small. Insert the pointed hammer 5 at the bottom of the hammer seat 4 into the gap between the clamp and the pipe. First, using the hammer seat 4 as the fulcrum, turn the sleeve rod 1 to make the hammer seat 4 and the pointed hammer 5 rotate, and pry the clamp outward. Then, using the fulcrum 15 at the top of the hammer seat 4 as the fulcrum, turn the sleeve rod 1 again to make the hammer seat 4 and the pointed hammer 5 rotate, and continue to pry the clamp outward to remove it. When the fulcrum 15 is located on the outer side of the bottom of the fan-shaped groove 13, it is suitable for situations where the gap between the pipe clamp and the pipe is large. The fulcrum 15 is used to increase the length of the fulcrum, so that the pointed hammer 5 can effectively pry out the clamp. At the same time, it is also suitable for situations where the pipe clamp is located at the end of the pipe. The fulcrum 15 is used to contact the end of the pipe so that the pointed hammer 5 can effectively pry out the clamp. By adjusting the position of the control fulcrum column 15, the position of the fulcrum can be controlled and adjusted, thereby facilitating the removal of the clip in different situations and improving the applicability of the removal operation.

[0026] Furthermore, such as Figures 9 to 10 As shown, arc-shaped grooves 17 are provided on both sides of the fan-shaped groove 13; and protrusions 18 that slide in cooperation with the arc-shaped grooves 17 are fixed on both sides of the rotating arm 14. Specifically, the arc of the arc groove 17 is the same as the arc of the fan-shaped groove 13; when the rotating arm 14 rotates, it drives the protrusion 18 to slide along the arc groove 17, thereby effectively improving the stability of the rotating arm 14, as well as the stability and firmness of the rotating arm 14 after it is fixed.

[0027] Working principle: Based on the actual operating conditions, the size of the operating space, and the required force, the operator adjusts the combined length of the sleeve rod 1 and the extension rod 2 to adjust the lever arm length when prying the clamp. When the extension rod 2 is completely inside the inner cavity of the two sleeve rods 1, the external threaded blocks 7 at both ends of the extension rod 2 are fixed with the threaded engagement at the bottom of the inner cavity of the sleeve rod 1. At this time, the length of the removal tool is the shortest and the lever arm length is the shortest. Although the force required for the removal operation is the greatest, it is convenient for the operator to operate in a confined space. Rotating one sleeve rod 1 causes the thread at the bottom of its inner cavity to rotate relative to the external threaded block 7 of the extension rod 2 located within the inner cavity of the sleeve rod 1. This loosens the fixation between the external threaded block 7 and the sleeve rod 1, allowing the external threaded block 7 to slide inside the sleeve rod 1. Pulling the extension rod 2 to slide it outward from the sleeve rod 1 causes the external threaded block 7 to contact the thread at the opening of the inner cavity of the sleeve rod 1. Rotating the sleeve rod 1 then fixes the external threaded block 7 at the opening of the inner cavity of the sleeve rod 1. In this way, the length of the two sleeve rods 1 is extended by half the length of the extension rod 2, thereby extending the length of the removal tool and the lever arm. At this point, the force required for removal is reduced, but the space required for operation is relatively increased. Similarly, the other half of the extension rod 2 is also moved out from the other sleeve rod 1 and fixed by the external threaded block 7 at this end and the threaded engagement at the inner cavity opening of the sleeve rod 1; that is, the length of the entire extension rod 2 is extended between the two sleeve rods 1; at this time, the length of the tool is the largest, the lever arm is the largest, the force required for the tool removal operation is the smallest, but the space required for the operation is also the largest. Depending on the location of the pipe clamp, use either a flat shovel head 3 or a pointed hammer head 5 to remove the clamp; insert the flat shovel head 3 into the gap between the clamp and the pipe, and use the end of the flat shovel head 3 near the sleeve 1 as a fulcrum to turn the sleeve 1, causing the flat shovel head 3 to rotate and pry the clamp outward. When the fulcrum 15 is located on the top outside of the fan-shaped groove 13, it is suitable for situations where the gap between the pipe clamp and the pipe is small. Insert the pointed hammer 5 at the bottom of the hammer seat 4 into the gap between the clamp and the pipe. First, using the hammer seat 4 as the fulcrum, turn the sleeve rod 1 to make the hammer seat 4 and the pointed hammer 5 rotate, and pry the clamp outward. Then, using the fulcrum 15 at the top of the hammer seat 4 as the fulcrum, turn the sleeve rod 1 again to make the hammer seat 4 and the pointed hammer 5 rotate, and continue to pry the clamp outward to remove it. When the fulcrum 15 is located on the outer side of the bottom of the fan-shaped groove 13, it is suitable for situations where the gap between the pipe clamp and the pipe is large. The fulcrum 15 is used to increase the length of the fulcrum, so that the pointed hammer 5 can effectively pry out the clamp. At the same time, it is also suitable for situations where the pipe clamp is located at the end of the pipe. The fulcrum 15 is used to contact the end of the pipe so that the pointed hammer 5 can effectively pry out the clamp. By adjusting the length of the lever arm composed of the sleeve rod 1 and the extension rod 2, and by selecting the flat shovel head 3 or the pointed hammer head 5, it is easier for workers to remove pipe clamps in different states in different operating spaces. This makes the operation easier for workers and reduces the difficulty of the removal work and the probability of injury.
