Referring to fig. 3b, the present embodiment proposes a specific structure of the locking mechanism: the locking mechanism comprises a limit baffle (the second limit baffle 4.3.3 corresponds to the second turning claw, the first limit baffle 3.5.4 corresponds to the first turning claw 3.3.1), a pin shaft is arranged on the turning claw in a penetrating mode to realize rotation of the turning claw, a limit groove is formed in the head of the pin shaft, and the limit baffle is inserted into the limit groove to limit rotation of the pin shaft. The locking structure adopting the structure has the advantages of simple structure, easy manufacture and low cost.
Specifically, the limit baffle is detachably arranged on the bearing piece 3 and the climbing frame 4. For example, two groups of bolt holes can be formed in the bearing piece 3 and the climbing frame 4, and when bolts penetrating through the limiting baffle are installed in the first group of bolt holes, the limiting baffle is inserted into an annular positioning groove formed in the end part of the pin shaft, so that the pin shaft is limited to play a role in axial positioning, and the pin shaft is prevented from loosening. When the bolts penetrating through the limit baffle are arranged in the second group of bolt holes, the limit baffle is inserted into the special-shaped limit groove at the inner side of the annular locating groove, and at the moment, the pin shaft cannot rotate, so that the rotation of the turning claw can be locked.
Further, referring to fig. 2e and fig. 3b, a limiting protrusion (such as a mounting flat key) is arranged on the outer side wall of the pin shaft (including the first pin shaft 3.5.1 and the second pin shaft 4.3.1), a positioning groove is arranged on the inner wall of the through hole for the pin shaft to pass through, and the limiting protrusion is accommodated in the positioning groove to fixedly connect the turning claw and the pin shaft. Through the cooperation of the limiting bulge and the positioning groove, the circumferential rotation of the pin shaft is limited, and meanwhile, the installation process of the turning claw and the pin shaft is very simple.
Further, the mating contact surfaces of the prongs (including the first prong 3.3.1 and the second prong) are provided with a layer of elastomeric material by fasteners (e.g., screws). Through setting up the elastic material layer, thereby the elastic material layer is out of shape under external force has guaranteed to turn over claw and outer claw boots 3.4.1 or interior claw boots 5.1.1 can closely laminate in order to bear the weight together.
In this embodiment, referring to fig. 3a, the climbing frame 4 includes two side plates and a base connecting the two side plates, the supporting frame 5 is located in a concave space formed by the two side plates and the base, and the supporting frame 5 and the climbing frame 4 can be hung on the outer side of the same layer of bearing member 3.
Because the supporting frame 5 is hung on the bearing member 3 on the upper layer of the climbing frame 4 in the prior art, that is, the supporting frame 5 and the climbing frame 4 are not on the same layer, the climbing frame 4 and the supporting frame 5 at least need to occupy at least two layers of heights (therefore, in the prior art, a multi-layer concrete main structure is generally adopted to install the existing self-elevating support system, that is, the self-elevating support system can be installed after the concrete main structure is at least constructed for two layers, in addition, the self-elevating support system occupies the multi-layer structure, so that the follow-up secondary structure, external wall painting and other follow-up construction operations are inconvenient). In this embodiment, the supporting frame 5 is accommodated in the concave space formed by the climbing frame 4, so that the supporting frame 5 and the climbing frame 4 can be simultaneously hung on the side surface of the bearing member 3 on the same layer, thus the supporting frame 5 and the climbing frame 4 occupy a layer of space together, and the self-lifting supporting system can be installed after the concrete main structure is constructed for one layer, so that the construction steel platform 1 can be inserted into the concrete main structure construction as soon as possible. In addition, the self-lifting supporting system only occupies one layer of structure, so that the follow-up secondary structure and the follow-up construction operations such as external wall painting are facilitated. That is, the same-floor frame type supporting lifting system achieves the same-floor climbing effect (same-floor climbing means that the supporting frame 5 and the climbing frame 4 can be hung on the bearing piece 3 on the same floor at the same time).
Referring to fig. 4a, a guide assembly 5.3 is mounted on the side of the support frame 5, guide grooves 4.1.1 are formed in the sides of the climbing frame 4, which are close to each other, and the guide assembly 5.3 is accommodated in the guide grooves 4.1.1 to guide the lifting of the support frame 5.
The guide sliding pair is formed by the guide assembly 5.3 and the guide groove 4.1.1 of the climbing frame 4, so that the mutual guiding effect of the supporting frame 5 and the climbing frame 4 in the movement process is ensured, that is, the mutual climbing of the frames is guided (the mutual climbing of the frames refers to the relative movement between the climbing frame 4 and the supporting frame 5).
Further, the guide assembly 5.3 comprises a guide holder 5.3.1 fixed on the side of the support frame 5 and a wear plate 5.3.2 detachably mounted on the outer side of the guide holder 5.3.1. The material of the wear-resisting plate 5.3.2 is ZCUSn10P1. The guide assembly 5.3 is attached to the support frame body 5.1 by means of screws. The wear resistance of the guide assembly 5.3 is improved by providing wear plates 5.3.2. The thickness of the wear-resistant plate 5.3.2 is adjustable so as to adjust the distance between the support frame 5 and the climbing frame 4, and the adjustable distance ensures the smooth movement of the support frame 5 and the climbing frame 4.
The jacking process of the jacking supporting system of the jacking mould is as follows (comprising two large jacking steps of the supporting frame 5 and the climbing frame 4).
When the telescopic mechanism 6 extends (the cylinder body extends relative to the telescopic rod), the lower flange 6.2 of the telescopic mechanism is contacted with the bottom of the supporting frame 5 step by step, and the upper flange 6.1 of the telescopic mechanism is separated from the spring box 5.2 step by step, so that the lower flange 6.2 supports the supporting frame 5 to continuously rise in the extending motion, and the bottom of the supporting frame 5 and the lower flange 6.2 can slide under external force. During the movement, the load of the construction steel platform 1 is transferred to the telescopic mechanism 6 via the upper flange 6.1. The head of the telescopic mechanism 6 adopts a spherical hinge structure 6.3 to ensure the self-centering effect in the telescopic movement. When the supporting frame 5 rises to the proper position, the telescopic mechanism 6 makes retraction movement (namely the cylinder body slightly moves downwards for a certain distance), so that the inner claw shoes 5.1.1 of the supporting frame 5 and the first turning claw 3.3.1 are simultaneously attached to the multiple surfaces to jointly bear force, and at the moment, the supporting frame 5 is hung on the bearing piece 3. Of course, when the retraction movement is performed, if the inner claw shoes 5.1.1 and the first turning claws 3.3.1 of the supporting frame 5 cannot be bonded in multiple planes due to installation deviation, overlarge structural construction deviation and large deformation under large load in construction, the positions of the supporting frame 5 on the lower flange 6.2 can be adjusted through external force so as to realize that the inner claw shoes 5.1.1 and the first turning claws 3.3.1 are bonded in multiple planes simultaneously to bear force together. The continuous retraction realizes gradual lamination of the upper flange 6.16.1 and the spring box 5.2, and after the jacking is finished, the load of the construction steel platform 1 is sequentially transferred to the upper flange 6.1, the supporting frame 5, the bearing piece 3 and the turnover concrete structure embedded part 2 through the supporting upright post 7 until reaching the concrete main structure. In the jacking process, the load of the construction steel platform 1 is sequentially transferred to the upper flange 6.1, the spherical hinge structure 6.3, the bottom of the climbing frame 4, the second turning claw, the bearing piece 3 and the turnover concrete structure embedded part 2 through the supporting upright post 7 until the construction steel platform is in a concrete main structure (the concrete section specifically depicts the jacking of the climbing frame 4).
When the supporting frame 5 is lifted to the upper layer of bearing pieces 3, the climbing frame 4 can be lifted to move upwards through the telescopic mechanism 6. The second turning claw of the climbing frame 4 is contacted with the outer claw boots 3.4.1 of the bearing piece 3 in the lifting process of the climbing frame 4, so that the second turning claw is turned over inside the climbing frame 4, the second turning claw is gradually separated from contact with the outer claw boots 3.4.1 and turned over under self gravity when the climbing frame 4 continuously ascends, and meanwhile, the second turning claw is in a horizontal state in a natural state through the limit of the top block. Then, the telescopic mechanism 6 extends (namely, the telescopic rod moves downwards), so that the climbing frame 4 is driven to descend, and when the self-centering structure of the second turning claw and the outer claw boot 3.4.1 of the climbing frame 4 is used for realizing the falling position, the position deviation can be eliminated, and the self-centering is in a plane contact state. In the motion process, the spherical hinge structure 6.3 is in a free sliding and rotating state, so that the second turning claw and the outer claw boot 3.4.1 are simultaneously attached to each other for bearing force after the lifting is finished. Of course, the lifting can be performed as desired by non-whole layers. The lifting function enables the climbing frame 4 to be mounted centrally on the support 3 (this section specifically describes the lifting of the support frame 5).
The lowering process of the self-lifting supporting system of the top die is as follows.
Firstly, the retraction movement of the telescopic mechanism 6 lifts the climbing frame 4 (the telescopic rod moves upwards to enable the second turning claw and the outer claw boots 3.4.1 to be separated from support), then the second hexagonal head 4.3.4 is rotated to drive the second turning claw to turn over inside the climbing frame 4 and lock the second turning claw, and then the extension movement of the telescopic mechanism 6 (the telescopic rod moves downwards) enables the climbing frame 4 to move downwards to the position of the next layer of bearing piece 3 and restore the second turning claw to enable the climbing frame 4 to be in a horizontal state (namely, the locking is released and the second turning claw is in an overhanging state), and the second turning claw and the outer claw boots 3.4.1 are simultaneously attached to each other in a multi-face manner to jointly bear force, so that the climbing frame 4 is lowered. After the climbing frame 4 descends, firstly, the telescopic mechanism 6 stretches to move (the cylinder body moves upwards) so that the supporting frame 5 and the first turning claw 3.3.1 are separated from contact, then the first hexagonal heads 3.5.3 of the upper layer and the lower layer of bearing pieces 3 rotate to drive the second turning claw to turn over inside the bearing pieces 3 and lock, and then, the telescopic mechanism 6 retracts to move, so that the supporting frame 5 moves down to the position of the next layer of bearing pieces 3 and restores the horizontal state of the first turning claw 3.3.1, and the multiple surfaces of the first turning claw 3.3.1 and the inner claw boots 5.1.1 are simultaneously attached to the common bearing, thereby realizing the descending of the supporting frame 5. Of course, the descent can be non-whole-layer descent according to construction requirements. After the descent is finished, the telescopic mechanism 6 can be adopted to bear the load of the construction steel platform 1 to be sequentially transferred to the climbing frame 4, the bearing piece 3 and the turnover concrete structure embedded part 2 until the concrete main structure.
The self-lifting supporting system for the top die has the following beneficial effects:

2. The cylinder body and the support frame 5 can move, the position of the support frame 5 on the lower flange 6.2 is adjusted by external force, so that the inner claw shoe 5.1.1 of the support frame 5 is matched with the first claw turning component 3.3.3, and the position of the second claw turning inserted into the inner claw shoe 5.1.1 is adjusted, and the accuracy of the position of the support frame 5 on the bearing piece 3 when the support frame 5 is lifted is ensured;
3. the spherical hinge structure 6.3 and the buffer balance mechanism are matched for use, so that the effective release of internal force between structural members in the action process of a supporting lifting system is ensured, the cylinder body and the supporting frame 5 are matched for moving, the two points are matched together, on one hand, the accuracy of the lifting position of the supporting frame 5 and the climbing frame 4 on the upper position of the bearing piece 3 is ensured, and on the other hand, the adaptability to the installation deviation, the construction deviation and the lifting operation under the influence of heavy load in construction (the construction deviation and the construction load are external factors which are not centered, and the design of the internal guiding centering structure is insufficient, the external factors and the internal factors are improved, so that the centering is ensured);
4. the same-layer frame type supporting lifting system has the advantages of simple structure, convenient disassembly and stable and reliable work.
