Technical Field

[0001] The utility model belongs to the field of auxiliary equipment for construction hoisting, and specifically relates to a steel pipe pile hook releaser. Background Art

[0002] In a water operation environment, the construction hoisting of steel pipe piles is a key link. However, when the steel pipe pile is hoisted in place, the hanging buckle of the steel casing is often at a relatively high position, which makes the subsequent hook unhooking operation complicated and dangerous.

[0003] The traditional method is to use a crane to lift the staff to a high place to unhook the hook and the lifting lug, but this method has significant safety risks. Due to the particularity of water construction conditions, such as the instability of the operation platform and the unpredictability of the water area environment, it is very difficult to ensure the safety of the operators. Therefore, the existing hook operation methods have obvious deficiencies in terms of safety and efficiency.

[0004] To solve this problem, there is an urgent need for a new technology or equipment that can quickly, conveniently and safely perform the hook releasing operation to improve the overall safety and efficiency of water steel pipe pile construction. Summary of the Utility Model

[0005] The utility model provides a steel pipe pile hook releaser, which solves the problem that manual hook unhooking has great potential safety hazards and improves the safety and construction efficiency of water steel pipe pile construction.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A steel pipe pile hook releaser for use in cooperation with a steel casing, comprising a main body member, a pin, a spring rod, a spring and a pull rope.

[0008] A groove is formed at the bottom of the main body member, and the groove is adapted to the side wall of the steel casing. A passage is formed on one side of the main body member, and the passage passes through the groove and forms a passage end on the other side of the main body member.

[0009] The spring is sleeved on the spring rod, the spring rod is placed in the passage, one end of the spring rod is fixedly connected to the pin, and the other end of the spring rod is connected to the pull rope.

[0010] Furthermore, one end of the spring is fixedly connected to the side of the main body member where the passage is formed, and the other end of the spring abuts against the pin.

[0011] Further, it also includes a latch plate, which is placed in the groove of the main body. The latch plate is fixedly connected to both sides of the groove. The gap between the two latch plates is larger than the thickness of the side wall of the steel casing. There are holes on the latch plate, and the latch passes through the holes on the latch plate and mates with the end of the passage.

[0012] Further, it also includes a spring plate, which is fixedly connected to one side of the main body where the passage is opened. There are holes on the spring plate, and the spring rod passes through the holes on the spring plate and is connected to the pull rope.

[0013] Further, one end of the spring is fixedly connected to the spring plate, and the other end of the spring abuts against the latch.

[0014] Further, there is a limit block on the main body, which is placed at the upper end of the passage. The width of the gap between the limit block and the groove is larger than the length of the latch.

[0015] Further, there are holes opened above the main body for hoisting.

[0022] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Next, in combination with the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described.

[0024] Embodiment 1

[0025] As Figure 1 shown, this embodiment provides a steel pipe pile hook releaser for use in conjunction with a steel casing 9. The steel casing 9 is provided with holes. The steel pipe pile hook releaser includes a main body member 1, a pin plate 2, a pin 3, a spring rod 4, a spring 5, a spring plate 6, and a pull rope 7.

[0026] Specifically, a groove 11 is provided at the bottom of the main body member 1. Two pin plates 2 are welded to both sides of the inner wall of the groove 11. The gap between the two pin plates 2 is greater than the side wall thickness of the steel casing 9, so that the hook releaser device can be sleeved on the side wall of the steel casing 9.

[0027] A passage 12 is provided on the side of the main body member 1 away from the groove 11. The passage 12 passes through the internal space of the groove 11 until an unpenetrated opening is formed on the other side of the main body member 1. The above opening is the end 121 of the passage. A spring plate 6 is welded on the side of the main body member 1 where the passage 12 is provided. The spring plate 6 is provided with a hole. The spring rod 4 is placed in the above passage 12. One end of the spring rod 4 is welded to the pin 3, and the other end passes through the hole on the spring plate 6 and is connected to the pull rope 7.

[0028] The pin plate 2 is provided with a hole corresponding to the position of the passage 12, and the size of the above hole is matched with the size of the pin 3. The pin 3 passes through the hole on the above pin plate 2 and is matched with the end 121 of the passage.

[0029] The spring 5 is sleeved on the spring rod 4. One end of the spring 5 is welded to the spring plate 6, and the other end abuts against the pin 3. When the pull rope 7 pulls the spring rod 4, the pin 3 moves to apply pressure to the spring 5. After the pin 3 releases the steel casing 9, the steel casing 9 is separated from the hook releaser device, and the spring 5 helps the pin 3 to quickly reset for the next use.

[0030] Among them, the main body part 1 is the basis for installing other structural parts. The groove 11 is connected to the passage 12 and cooperates with the bolt 3 to realize the locking and releasing of the steel casing 9. The bolt plate 2 is fixed in the groove 11, providing stable support and guidance for the bolt 3. At the same time, the bolt plate 2 also enhances the connection strength between the main body part 1 and the steel casing 9. The spring rod 4 is a component connecting the bolt 3 and the pull rope 7, which transmits the pulling force of the pull rope 7 to the bolt 3, enabling the bolt 3 to move along a predetermined trajectory. The spring 5 provides the necessary elastic force and reset function for the movement of the bolt 3, enabling the bolt 3 to maintain a stable state without external force. The spring plate 6 is fixed to the main body part 1 and connected to the spring 5, providing a stable installation position for the spring 5.

[0031] Specifically, a limit block 13 is also provided on the main body part 1. The limit block 13 has a trapezoidal structure and is located at the upper end inside the passage 12. The gap width between the limit block 13 and the groove 11 is greater than the length of the bolt 3. The limit block 13 is used to limit the movement range of the bolt 3, so that when the spring rod 4 drives the bolt 3 to move, it can both limit the bolt 3 and prevent it from disengaging from the steel pipe pile unhooking device, and also enable the bolt 3 to be completely withdrawn from the groove 11 to release the steel casing 9.

[0032] A hole is opened above the main body part 1 for connecting to a crane, thereby realizing the hoisting of the steel pipe pile. A weight-reducing groove is also opened on the main body part 1, reducing the weight of the main body part 1 and improving the economy and practicality of the equipment.

[0033] The above is the structural description of a steel pipe pile unhooking device provided in this embodiment. The principle of this embodiment is:

[0034] As Figure 1 shown, pull the pull rope 7 to make the spring rod 4 drive the bolt 3 to move out of the bolt plate 2 to the limit block 13. The spring 5 is compressed. Put the steel pipe pile unhooking device on the side wall of the steel casing 9, so that the side wall of the steel casing 9 is placed between the two bolt plates 2, and the holes on the bolt plate 2 are aligned with the holes on the side wall of the steel casing 9. Release the pull rope 7, and the bolt 3 passes through the holes on the bolt plate 2 and the holes on the steel casing 9 under the thrust of the spring 5 to lock the steel casing 9.

[0035] Connect the steel pipe pile unhooking device to the crane through the hole on the main body part 1 to realize the hoisting of the steel pipe pile. After hoisting the steel pipe pile to the predetermined position, pull the pull rope 7 to make the spring rod 4 drive the bolt 3 to move out of the bolt plate 2, realizing the separation of the steel pipe pile unhooking device from the steel casing 9 and achieving the effect of unhooking.

[0036] Embodiment 2

[0037] As Figure 2As shown in the figure, there are no holes on the steel casing 9, but lifting lugs 8 are fixed on the outer wall of the steel casing 9. Then, the steel pipe pile unhooking device is sleeved on the above-mentioned lifting lugs, so that the lifting lugs are placed between the two pin plates 2, and the holes on the lifting lugs are aligned with the holes on the side wall of the steel casing 9. Other steps are the same as those in Embodiment 1.

[0038] The embodiments of the present invention have been described in detail above, but the above content is only the preferred embodiment of the present invention and cannot be considered as limiting the implementation scope of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
