Description

Technical Field

[0001] This utility model relates to the field of hoisting tools, and in particular to a U-hole hoisting lock. Background Technology

[0002] In the field of machinery manufacturing, the assembly of parts is a key link. During the hoisting and assembly of parts, hoisting tools such as lifting rings, hooks, and lugs are usually needed to lift the parts and transport them to the installation position of the equipment for subsequent assembly operations. These hoisting tools play an indispensable role in practical applications, providing convenience and protection for the handling and assembly of parts.

[0003] However, in existing technologies, when using lifting tools such as lifting rings or hooks, it is often necessary to pre-set lifting screw holes on the surface of the workpiece to securely install the lifting rings or hooks onto the workpiece. This process requires drilling screw holes on the workpiece surface using equipment such as drilling machines. During the lifting process, the screw holes will be subjected to significant tensile force, which may cause deformation of the workpiece and affect its quality. In addition, most existing workpiece surfaces have U-shaped holes, but existing lifting tools such as lifting rings or hooks lack a structure that can effectively connect with the U-shaped holes. This makes it impossible to fully utilize the existing U-shaped holes on the workpiece surface for lifting, resulting in low lifting efficiency.

[0004] To address the aforementioned issues, this application proposes a U-hole hoisting lock. Utility Model Content

[0005] Based on the technical problems existing in the background art, this utility model proposes a U-hole hoisting lock.

[0006] This utility model proposes a U-hole hoisting lock, which includes a hoisting lock and an angle iron;

[0007] The angle iron has a U-shaped hole, and the lifting lock is used to pass through the U-shaped hole and rotate to engage with the angle iron.

[0008] The lifting lock includes a locking rod, a locking head, an elastic element, and a lifting ring. The locking head is fixed to one end of the locking rod and fits into a U-shaped hole. The elastic element is fitted onto the locking rod and abuts against the locking head, and the elastic element can slide on the locking rod. The lifting ring is fixed to the other end of the locking rod.

[0009] Preferably, the lock head includes an elliptical lock head and a fixing block. The fixing block is fixed to one end of the lock rod, and the elliptical lock head is fixed to the side of the fixing block away from the lock rod. The elliptical lock head is adapted to the U-shaped hole.

[0010] Preferably, the surface of the elliptical lock head is covered with a rubber layer for pressing against the angle iron.

[0011] Preferably, the elastic element includes an upper baffle and an elastic part. The upper baffle is fixedly fitted onto the other end of the locking rod, and the upper baffle is connected to an elastic part that is sleeved on the locking rod and abuts against the fixing block.

[0012] Preferably, the elastic part includes a lower baffle and a spring, the bottom side of the upper baffle is fitted with a spring sleeved on the locking rod, and the bottom end of the spring is fitted with a lower baffle that is slidably sleeved on the locking rod and abuts against the fixing block.

[0013] Preferably, the outer surface of the lifting ring is provided with anti-slip texture.

[0014] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0015] 1. Angle irons are usually installed on parts for fixing them to other parts. U-shaped holes are provided on the angle irons. When hoisting parts, the elliptical lock head at the bottom of the locking rod is passed through the U-shaped hole. The elastic part on the locking rod presses against the surface of the angle iron and retracts. The hoisting lock is rotated 90 degrees by holding the lifting ring so that the elliptical lock head and the angle iron form a cross structure. After releasing the hand, the elastic part returns to its original position, and the elliptical lock head is tightly attached to the bottom of the angle iron, thus completing the fixation. The parts can be hoisted using the lifting ring. The above design avoids drilling additional screw holes on the surface of the parts by effectively connecting the hoisting lock with the U-shaped hole on the angle iron of the parts. This reduces the risk of deformation of the parts due to the force on the screw holes during hoisting, thus improving the quality of the parts. At the same time, it makes full use of the existing U-shaped hole on the surface of the parts, improving hoisting efficiency.

[0016] 2. By utilizing the elastic element in the lifting lock, when disassembly is required, simply apply a certain force to the lifting lock to deform the elastic element, which can quickly release the locking structure between the lifting lock and the angle iron, achieving rapid overall disassembly and improving the efficiency and convenience of lifting operations.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] like Figure 1-3 As shown, the present invention proposes a U-hole lifting lock, which includes a lifting lock 1 and an angle iron 2;

[0023] An angle iron 2 has a U-shaped hole 21, and the lifting lock 1 is used to pass through the U-shaped hole 21 and rotate to engage with the angle iron 2;

[0024] The lifting lock 1 includes a locking rod 11, a locking head 12, an elastic element 13, and a lifting ring 14. The locking head 12 is fixed to one end of the locking rod 11 and is adapted to the U-shaped hole 21. The elastic element 13 is fitted on the locking rod 11 and abuts against the locking head 12. The elastic element 13 can slide on the locking rod 11. The lifting ring 14 is fixed to the other end of the locking rod 11.

[0025] Angle iron 2 is usually installed on the component workpiece for fixing it to other workpieces. U-shaped holes 21 are opened on the angle iron 2. When hoisting the component, the locking head 12 of the hoisting lock 1 is aligned with the U-shaped hole 21 of the angle iron 2 and passed through. Then, the hoisting lock 1 is rotated 90 degrees so that the locking head 12 and the bottom surface of the angle iron 2 form a locking fit. At the same time, the elastic element 13 undergoes elastic deformation due to contact with the surface of the angle iron 2, and tightly presses against the angle iron 2. During the hoisting operation, the external hoisting equipment hooks the lifting ring 14 and transmits the pulling force through the locking rod 11 to complete the hoisting of the component. The above design does not require additional drilling of screw holes on the surface of the component workpiece, avoids deformation of the workpiece due to the force of the screw holes, protects the quality of the component, and can quickly connect with the U-shaped hole 21 of the angle iron 2, improving hoisting efficiency.

[0026] In a specific embodiment, the lock head 12 includes an elliptical lock head 121 and a fixing block 122. The fixing block 122 is fixed to one end of the lock rod 11, and the elliptical lock head 121 is fixed to the side of the fixing block 122 away from the lock rod 11. The elliptical lock head 121 is adapted to the U-shaped hole 21. When the elliptical lock head 121 passes through the U-shaped hole 21, it passes through the U-shaped hole 21 by its own shape. After passing through, it rotates and lifts the lock 1. The long axis direction of the elliptical lock head 121 is offset from the opening direction of the U-shaped hole 21, forming a stable locking position with the bottom surface of the angle iron 2. The fixing block 122 serves to connect the elliptical lock head 121 and the lock rod 11, ensuring that the two are firmly connected and do not fall off when transmitting tension.

[0027] In a specific embodiment, the surface of the elliptical lock head 121 is covered with a rubber layer 123 for pressing against the angle iron 2. When the elliptical lock head 121 contacts and locks against the bottom surface of the angle iron 2, the rubber layer 123 on its surface directly presses against the bottom surface of the angle iron 2. During the hoisting process, the rubber layer 123 will undergo slight deformation due to the force, filling the gap between the elliptical lock head 121 and the bottom surface of the angle iron 2, increasing the friction between the elliptical lock head 121 and the angle iron 2, further improving the locking stability, preventing relative sliding during hoisting, and avoiding direct rigid contact between the elliptical lock head 121 and the angle iron 2, reducing wear between the two, and protecting the angle iron 2 and the elliptical lock head 121.

[0028] In a specific embodiment, the elastic element 13 includes an upper baffle 131 and an elastic part 132. The upper baffle 131 is fixedly fitted onto the other end of the locking rod 11. The upper baffle 131 is connected to the elastic part 132, which is sleeved on the locking rod 11 and abuts against the fixing block 122. When the lock head 12 in the hoisting lock 1 passes through the U-shaped hole 21, the surface of the angle iron 2 presses against the lower baffle 1321. The lower baffle 1321 drives the spring 1322 to contract upward along the locking rod 11. The spring 1322 generates elastic force. After the rotation and locking, the external force is released, the spring 1322 returns to its original state, and pushes the lower baffle 1321 to press tightly against the surface of the angle iron 2.

[0029] In a specific embodiment, the elastic part 132 includes a lower baffle 1321 and a spring 1322. The lower baffle 1322 is mounted on the bottom side of the upper baffle 131 and sleeved on the locking rod 11. The lower baffle 1321, which is slidably sleeved on the locking rod 11 and abuts against the fixing block 122, is mounted on the bottom end of the spring 1322.

[0030] During installation, angle iron 2 presses against lower baffle 1321, which slides along locking rod 11 and compresses spring 1322. Spring 1322 stores elastic potential energy. After locking, spring 1322 releases elastic potential energy, pushing lower baffle 1321 to reset and continuously press against angle iron 2. During disassembly, pressing down on lifting ring 14 causes locking rod 11 to move upper baffle 131 down, further compressing spring 1322. This allows the lifting lock 1 to be rotated, enabling the oval lock head 121 to be removed from U-shaped hole 21, thus completing the unlocking process.

[0031] In a specific embodiment, the outer surface of the lifting ring 14 is provided with anti-slip texture. During the lifting operation, the hook of the external lifting equipment contacts the lifting ring 14. The anti-slip texture on the outer surface of the lifting ring 14 increases the friction between the hook and the lifting ring 14. During the lifting process, even if it is subjected to vibration or slight external force displacement, the anti-slip texture can prevent the hook from slipping off the lifting ring 14, effectively avoiding lifting accidents caused by hook slippage, improving the safety of the lifting operation, and ensuring that the parts are stable and do not fall off during the lifting process.

[0032] The specific working principle of this utility model is as follows:

[0033] Confirm the position of the angle iron 2 and the U-shaped hole 21 on the component workpiece. Hold the lifting ring 14 and align the lock head 12 of the lifting lock 1 with the U-shaped hole 21. Pass the elliptical lock head 121 through the U-shaped hole 21. During the process, the lower baffle 1321 in the elastic element 13 first contacts the surface of the angle iron 2. Continue to push the lifting ring 14 downward. The lower baffle 1321 slides upward along the locking rod 11, compressing the spring 1322 sleeved on the locking rod 11. The top of the spring 1322 is limited by the upper baffle 131. At this time, the spring 1322 stores elastic potential energy.

[0034] After the elliptical lock head 121 has completely passed through the U-shaped hole 21, rotate the lifting ring 14 to drive the lock rod 11 and lock head 12 to rotate 90 degrees, so that the long axis of the elliptical lock head 121 is perpendicular to the opening direction of the U-shaped hole 21. The elliptical lock head 121 contacts the bottom surface of the angle iron 2 through the rubber layer 123 to form a locking structure.

[0035] Release the downward pressure on the lifting ring 14, the spring 1322 releases its elastic potential energy, pushes the lower stop plate 1321 to return to its original position along the locking rod 11, and presses tightly against the surface of the angle iron 2. At this time, the elliptical lock head 121 and the lower stop plate 1321 clamp the angle iron 2 from the bottom and top surfaces respectively, thus completing the fixing of the lifting lock 1 and the angle iron 2.

[0036] During hoisting, hook the hook of the external hoisting equipment onto the lifting ring 14, start the hoisting equipment, and the pulling force is transmitted through the lifting ring 14 to the locking rod 11, and then through the fixing block 122 to the elliptical lock head 121, which drives the angle iron 2 and the component workpieces to rise, thus completing the hoisting operation.

[0037] After hoisting is completed, press down on the lifting ring 14, and the locking rod 11 moves along the upper baffle 131 to further compress the spring 1322. Then, rotate the lifting ring 14 to rotate the entire hoisting lock 1 by 90 degrees so that the long axis of the elliptical lock head 121 is aligned with the opening direction of the U-shaped hole 21. Then, pull the lifting ring 14 upward to remove the elliptical lock head 121 from the U-shaped hole 21, thus completing the disassembly.

[0038] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model, and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
