Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0036] In the embodiment of the present application, by providing a tooling for hoisting the skirt pile sleeve diaphragm, the problem in the prior art that when hoisting the skirt pile diaphragm with a hoisting device, it cannot clamp and hoist from the thickened area at the edge of the skirt pile diaphragm according to the shape of the skirt pile diaphragm, resulting in a cumbersome hoisting process of the skirt pile diaphragm is solved. After hoisting, the skirt pile sleeve diaphragm can be firmly lifted, and the installation task of the diaphragm can be completed efficiently and conveniently. This diaphragm fixture tooling greatly facilitates the on-site construction, improves the work efficiency, saves the labor consumption cost, and makes the hoisting of the skirt pile sleeve diaphragm more convenient.

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the specification drawings and specific embodiments.

[0038] The embodiment of the utility model discloses a tooling for hoisting the skirt pile sleeve diaphragm.

[0039] According to FIG. Figure 1 -5, it includes a clamping mechanism 1 and a limit rotation device 2. The clamping mechanism 1 is arranged in a cross-symmetrical manner, and the limit rotation device 2 is inserted and connected between the clamping mechanisms 1. The clamping mechanism 1 includes: a connecting arm 11, and the connecting arm 11 is arranged in a long strip shape; a clamping hook 12, and the clamping hook 12 is connected to the end of the connecting arm 11. The clamping hooks 12 are arranged oppositely, and the connecting arm 11 and the clamping hook 12 are integrally arranged. The clamping hook 12 is arranged in a hook shape. During the clamping and hoisting of the diaphragm by the clamping mechanism 1, by utilizing the self-weight of the diaphragm and skillfully using the thickened steel ring at the edge of the diaphragm, when clamping and hoisting, the clamping hook 12 is embedded and hooked on the thickened steel ring at the edge of the diaphragm, so that the skirt pile sleeve diaphragm can be firmly lifted after hoisting. Through the cross arrangement of the connecting arms 11, similar to a scissor clamp, the clamping hook 12 can stably hook the thickened part at the edge of the diaphragm, and the diaphragm can be very conveniently hoisted to a high altitude. It is simple to manufacture and easy to operate.

[0040] Further, the limit rotation device 2 includes: an insertion pin 21, a circular hole is opened on the clamping mechanism 1, and the insertion pin 21 is slidably inserted and connected with the inner cavity of the circular hole; a nut limit ring 22, and the nut limit ring 22 is in threaded cooperation with the outside of one end of the insertion pin 21. The limit rotation device 2 further includes: a positioning mechanism 23, and the positioning mechanism 23 is clamped inside one end of the insertion pin 21, and the positioning mechanism 23 is used for positioning the nut limit ring 22. An external thread is opened at one end of the insertion pin 21, and the nut limit ring 22 is matched with the external thread. Thus, through the mutual cooperation between the head of the insertion pin 21 and the nut limit ring 22, the two connecting arms 11 can be limited inside, so that the two clamping mechanisms 1 can rotate around the axis of the insertion pin 21 for fixed-axis rotation to facilitate the clamping of the diaphragm.

[0041] Furthermore, the positioning mechanism 23 includes: a plug-in head 231, a groove is provided at one end of the inserted pin 21, and the plug-in head 231 is in snap-fit with the inner cavity of the groove; a connection disk 232, the connection disk 232 is connected to one end of the plug-in head 231, and the diameter of the connection disk 232 is larger than the diameter of the inserted pin 21; a positioning bracket 233, a plurality of positioning brackets 233 are installed on one side of the connection disk 232; an elastic snap-fit component 234, the elastic snap-fit component 234 is inserted inside the plug-in head 231 and the connection disk 232, and the plug-in head 231 is mutually snap-connected with the inserted pin 21 through the elastic snap-fit component 234. The plurality of positioning brackets 233 are arranged in a circular array, the positioning brackets 233 are inclined relative to the connection disk 232, and the positioning brackets 233 are made of an elastic material to elastically and obliquely support the nut limiting ring 22. By inserting the plug-in head 231 into the inside of the groove and then cooperating with the snap connection between the elastic snap-fit component 234 and the inserted pin 21, it is convenient to install and fix the relative position between the connection disk 232 and the inserted pin 21. Through the connection disk 232, it is convenient to install the plurality of positioning brackets 233, so that the positioning brackets 233 can limit the position of the nut limiting ring 22, prevent the nut limiting ring 22 from rotating and loosening outside the inserted pin 21 and disengaging from the inserted pin 21. Through the positioning of the nut limiting ring 22 by the positioning brackets 233, the cooperation between the inserted pin 21 and the nut limiting ring 22 is more stable.

[0042] Specifically, slots are provided inside the plug 231 and the connection plate 232. The elastic clamping component 234 is movably arranged inside the slots. The elastic clamping component 234 includes: a sliding frame 2341, which is symmetrically arranged and slidably arranged inside the slots. The sliding frame 2341 is arranged in a Z shape to facilitate increasing the installation space of the spring 2344; one-way clamping blocks 2342, which are connected to one end of the sliding frame 2341 and are arranged in opposite directions; guide rods 2343, which are fixedly installed inside the slots and are slidably inserted through the sliding frame 2341; and a spring 2344, which is movably sleeved outside the guide rods 2343 and is arranged between the sliding frames 2341. The one-way clamping blocks 2342 are provided with inclined surfaces, and the one-way clamping blocks 2342 are slidably inserted through the insertion pin shafts 21. The inner wall of the groove is provided with a clamping slot, and the one-way clamping blocks 2342 are mutually matched with the inner cavity of the clamping slot. The installation of the one-way clamping blocks 2342 is facilitated through the sliding frame 2341, so that the movement of the sliding frame 2341 can synchronously drive the movement of the one-way clamping blocks 2342, in order to unlock the clamping of the one-way clamping blocks 2342. Through the sliding insertion between the guide rods 2343 and the sliding frame 2341, linear limitation of the sliding of the sliding frame 2341 inside the slots is facilitated, making the sliding of the sliding frame 2341 more stable. Through the compression deformation of the spring 2344, elastic support for the sliding frames 2341 at both ends thereof is facilitated. While facilitating the support and reset of the sliding frame 2341, the cooperation between the one-way clamping blocks 2342 and the clamping slots is also made more stable. By relatively squeezing the ends of the two sliding frames 2341, the relative movement of the two one-way clamping blocks 2342 is driven, so as to facilitate the separation of the one-way clamping blocks 2342 from the inner cavity of the clamping slots, in order to unlock the clamping of the one-way clamping blocks 2342, so as to realize the disassembly of the positioning mechanism 23, and thus facilitate the disassembly of the nut limiting ring 22.
