[0031] refer to Figure 1-4 , shows a decoupling device for steel pipe pile hoisting, comprising a main body 1, an insertion rod 2, an elastic member 3, a pulley 4 and a steel wire rope 5;

[0032] The main body 1 includes a base block 11, and a first support plate 12 and a second support plate 13 are arranged in parallel at the bottom of the base block 11. The first support plate 12 is provided with a first plug hole 121 that runs horizontally therethrough, and the second support plate 13 is provided with a second plug hole 131 that is coaxially arranged with the first plug hole 121; one end surface of the first support plate 12 is connected to a horizontally arranged mounting tube 14, and a baffle 142 is arranged on the end of the mounting tube 14 away from the first support plate 12, and a guide groove 141 that communicates with the inside and outside is opened on the side wall of the mounting tube 14; wherein, the base block 11, the first support plate 12 and the second support plate 13 form an integrated structure in the shape of a door, and the overall structure is stable and not easy to deform.

[0033] The insertion rod 2 can be slidably inserted into the first insertion hole 121 and the second insertion hole 131, and at least a part of the insertion rod 2 is located inside the installation tube 14. A connecting rod 21 is provided on the side wall of the part of the insertion rod 2 located inside the installation tube 14, and the connecting rod 21 extends out from the guide groove 141; wherein, when the insertion rod 2 is inserted on the first support plate 12 and the second support plate 13, the base block 11, the first support plate 12, the second support plate 13 and the insertion rod 2 form a square structure without a hinge structure, which can well bear the steel pipe pile.

[0034] The elastic member 3 is arranged in the installation tube 14, and applies a driving force to the insertion rod 2 to approach the second support plate 13; the pulley 4 is arranged below the installation tube 14; one end of the wire rope 5 is connected to the connecting rod 21, and the wire rope 5 is slidably wound around the pulley 4.

[0035] Specifically, when in use, the unhooking device for steel pipe pile lifting is arranged on the lifting equipment, and the steel pipe pile is hung on the insertion rod 2 by cables and hooks; when unhooking is required, the steel wire rope 5 is pulled by means of an instrument or manpower, and the steel wire rope 5 drives the insertion rod 2 to move axially through the connecting rod 21, so that one end of the insertion rod 2 is disengaged from the second socket 131 of the second support plate 13, thereby achieving unhooking; when the steel wire rope 5 is released, the insertion rod 2 is reset under the elastic force of the elastic member 3.

[0036] The connecting rod 21 is slidably disposed in the guide groove 141 , and the guide groove 141 limits the moving path of the connecting rod 21 , so that the insertion rod 2 can move along a prescribed route, and the elastic member 3 cannot completely push the insertion rod 2 out of the installation tube 14 .

[0037] The function of the pulley 4 is to change the pulling direction of the steel wire rope 5. Figure 2 As shown, when the steel pipe pile is hoisted to a high altitude, the steel wire rope 5 can be pulled downward, and the pulley 4 can enable the steel wire rope 5 to pull the connecting rod 21 laterally, thereby causing the insertion rod 2 to move axially.

[0038] The unhooking device for steel pipe pile hoisting does not adopt hinged connection, so that its structural strength is higher, which is conducive to bearing steel pipe piles with higher loads, and the overall structure is relatively simple, the manufacturing cost is low, and the practicability is strong.

[0039] For details of the above scheme, please refer to Figure 2 , the elastic member 3 is a spring.

[0040] In some embodiments, reference Figure 2 and Figure 4 The insertion rod 2 includes a thick diameter section 22 and a thin diameter section 23. The diameter of the thick diameter section 22 is larger than that of the thin diameter section 23. The elastic member 3 is sleeved on the thin diameter section 23. One end of the elastic member 3 abuts against the end surface of the thick diameter section 22, and the other end abuts against the baffle 142. In this way, the spring can be prevented from being displaced inside the mounting tube 14, thereby improving the installation stability of the spring.

[0041] In addition, refer to Figure 2 and Figure 3 In order to avoid interference between the thin-diameter section 23 and the baffle 142 , a third insertion hole 143 is formed on the baffle 142 for the thin-diameter section 23 of the insertion rod 2 to pass through.

[0042] In some embodiments, in order to facilitate the elastic member 3 to drive the insertion rod 2 to smoothly insert into the second insertion hole 131, refer to Figure 4The end of the thick diameter section 22 away from the thin diameter section 23 is set as a cone head 221. In this way, the precision requirement for the opening position of the second insertion hole 131 can be reduced, and the manufacturing difficulty can be reduced.

[0043] Specifically, the first plug hole 121 and the second plug hole 131 have the same diameter, and there is a gap of 0.5-3 mm between the first plug hole 121 and the thick-diameter section 22 , so as to prevent the insertion rod 2 from getting stuck in the first plug hole 121 or the second plug hole 131 .

[0044] For details of the above scheme, please refer to Figure 1 and Figure 2 A hanging plate 15 is provided on the top of the base block 11, and a hanging hole 151 is provided on the hanging plate 15. In this way, the hanging hole 151 can be used to connect the unhooking device for steel pipe pile hoisting to the hoisting equipment.

[0045] Specifically, in order to facilitate the setting of the pulley 4, refer to Figure 2 , and also includes a pulley frame 41, which is welded below the mounting cylinder 14, and the pulley 4 is rotatably disposed on the pulley frame 41.

[0046] When assembling the unhooking device for steel pipe pile hoisting, the elastic member 3 is firstly arranged on the plug rod 2, and then the plug rod 2 is sequentially inserted into the installation tube 14 through the second insertion hole 131 and the first insertion hole 121, and then the connecting rod 21 is inserted into the installation tube 14 from the guide groove 141 of the installation tube 14 and fixed to the plug rod 2;

[0047] Among them, regarding the connection method of the connecting rod 21 and the insertion rod 2, in one embodiment, the side wall of the insertion rod 2 is provided with a connecting hole 24, one end of the connecting rod 21 is inserted into the connecting hole 24, and the connecting rod 21 is welded to the insertion rod 2. In this way, the connection between the connecting rod 21 and the insertion rod 2 is stable.

[0048] Regarding the connection method between the connecting rod 21 and the insertion rod 2, in another embodiment, the side wall of the insertion rod 2 is provided with a connecting hole 24, the connecting hole 24 is provided with an internal thread, one end of the connecting rod 21 is provided with an external thread, and the connecting rod 21 is threadedly connected to the connecting hole 24.
