Description

Technical Field

[0001] This invention relates to the field of precast concrete tetrahedron technology, and in particular to a hook replacement mechanism and a tetrahedron formwork disassembly device. Background Technology

[0002] Tetrahedral prefabrication is an advanced technology in architectural and structural design that uses concrete to create prefabricated tetrahedral components. This method can be used in various building projects, including residential, commercial, and industrial buildings, as well as infrastructure projects. Tetrahedrals are also frequently used for protection in slag heaps. Due to the large volume of demand, mobile tetrahedral prefabrication devices are employed for efficient and high-precision prefabrication. Tetrahedral formwork is used for casting during the prefabrication process.

[0003] The existing tetrahedral prefabrication equipment requires the dismantling of the formwork after the casting is completed. During dismantling, the formwork is quickly dismantled using lifting equipment and hooks. However, most of the existing formwork hooks are directly welded to one side of the formwork. During long-term and repeated dismantling and lifting, the hooks may malfunction or be damaged, making it difficult to quickly dismantle and replace them. This affects the prefabrication efficiency of tetrahedrals and causes great inconvenience. Summary of the Invention

[0004] Given that most existing template hooks are directly welded to one side of the template, the hooks may malfunction or be damaged during repeated disassembly and lifting over a long period of time, making it difficult to quickly disassemble and replace the hooks, thus affecting the prefabrication efficiency of the tetrahedron, this invention is proposed.

[0005] Therefore, the object of the present invention is to provide a hook replacement mechanism.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a hook replacement mechanism, including an installation component, comprising an installation part and a lifting part, wherein the lifting part is disposed on one side of the installation part; and a reset component, comprising a back pressure part and a reset part, wherein the back pressure part is disposed on one side of the installation part, and the reset part is disposed within the installation part; the installation part includes an installation cylinder and an elastic clamping frame slidably disposed on one side of the installation cylinder; and the lifting part includes a lifting block slidably disposed within the installation cylinder, one end of which contacts the elastic clamping frame.

[0007] As a preferred embodiment of the hook replacement mechanism of the present invention, the mounting component further includes a hook, a plug disposed on one side of the hook, a mounting cylinder disposed on one side of the plug, and a first channel and a second channel opened on the outside of the mounting cylinder.

[0008] As a preferred embodiment of the hook replacement mechanism of the present invention, the lifting member further includes a first rotating shaft rotatably disposed on one side of the mounting cylinder, a first rotating handle disposed on the outside of the first rotating shaft, and a top block disposed on one side of the first rotating handle.

[0009] As a preferred embodiment of the hook replacement mechanism of the present invention, the lifting member further includes a toothed block disposed on the outside of the lifting block and a toothed groove disposed on the inside of the elastic clamping frame, wherein the toothed block extends into the toothed groove.

[0010] As a preferred embodiment of the hook replacement mechanism of the present invention, the back pressure component includes a second rotating shaft rotatably disposed inside the mounting cylinder, a second rotating handle rotatably disposed in the second channel, through holes opened on both sides of the lifting block, and an inner groove opened inside the lifting block, wherein the radius of the through holes is greater than the radius of the second rotating shaft.

[0011] As a preferred embodiment of the hook replacement mechanism of the present invention, the back pressure component further includes an irregularly shaped back pressure block disposed on the outside of the second rotating shaft, a wedge-shaped surface disposed on the outside of the elastic clamping frame, and a wedge-shaped notch disposed on one side of the mounting cylinder, wherein the wedge-shaped surface and the wedge-shaped notch are matched with each other.

[0012] In a preferred embodiment of the hook replacement mechanism of the present invention, the reset component includes a connecting plate disposed inside the mounting cylinder and a tension spring disposed on one side of the connecting plate, wherein the two ends of the tension spring are respectively connected to one side of the connecting plate and one side of the elastic clamping frame.

[0013] The beneficial effects of the hook replacement mechanism described in this invention are as follows: By using the installation component and the reset component in cooperation, this invention facilitates the quick disassembly, replacement, and fixed installation of hooks on the side walls of tetrahedral precast templates. Furthermore, no specific disassembly or installation tools are required during the disassembly and installation process, making disassembly convenient. This reduces the inconvenience caused by the fact that most existing template hooks are directly welded to one side of the template, which may malfunction or be damaged during repeated disassembly and lifting operations over a long period, making quick disassembly and replacement difficult and thus affecting the precast efficiency of tetrahedrals.

[0014] In actual use, it is difficult to quickly clamp and fix the template, which may cause the template to fall off during hoisting and disassembly, resulting in damage to the template.

[0015] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: a tetrahedral template disassembly device, including the above-mentioned hook replacement mechanism, and further including a structural component, including a structural member and a lifting member disposed on one side of the structural member, a clamping component; including a fixing member disposed on one side of the structural member and a clamping member disposed on one side of the lifting member, a rotating component, including a rotating member disposed on one side of the lifting member and a pressing member disposed on one side of the clamping member.

[0016] As a preferred embodiment of the tetrahedral template dismantling device of the present invention, the structural components include a casting template, a horizontal reinforcing bar disposed on one side of the casting template, and an adjustable hook disposed on the outside of the horizontal reinforcing bar. One end of the adjustable hook is connected to the horizontal reinforcing bar, and the other end is connected to the casting template.

The installation cylinder is disposed on one side of the casting template, and the hook is installed on one side of the installation cylinder through a column.

[0017] As a preferred embodiment of the tetrahedral template disassembly device of the present invention, the fixing member includes a fixing cylinder disposed on the upper side of the casting template and an annular plate disposed inside the fixing cylinder. The annular plate is disposed inside the fixing cylinder. The clamping member includes an installation sleeve disposed on one side of the extrusion member, an installation tube slidably disposed on one side of the extrusion member, a shaped pressure block rotatably disposed inside the installation sleeve, and a through groove opened on one side of the installation tube. One end of the shaped pressure block extends out of the through groove and contacts the annular plate.

[0018] The beneficial effects of the tetrahedral template dismantling device of the present invention are as follows: The present invention, through the cooperation of the clamping component and the rotating component, facilitates the quick clamping and fixing of the casting template during hoisting and dismantling. At the same time, after the hoisting is completed, the device is easy to dismantle, reducing the difficulty of quickly clamping and fixing the template during the hoisting and dismantling process of existing dismantling devices, which may cause the template to fall off and be damaged during the hoisting and dismantling process.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a hook replacement mechanism, including an installation assembly 100, comprising an installation member 101 and a lifting member 102, the lifting member 102 being disposed on one side of the installation member 101, and a reset assembly 200, comprising a back pressure member 201 and a reset member 202, the back pressure member 201 being disposed on one side of the installation member 101, and the reset member 202 being disposed within the installation member 101. The installation member 101 includes an installation cylinder 101a and a slidably disposed on the installation cylinder 101a. The elastic clamping frame 101b on one side of the cylinder 101a includes a lifting member 102, which is slidably disposed in the mounting cylinder 101a. The lifting block 102a is used to lift the elastic clamping frame 101b. One end of the lifting block 102a is in contact with the elastic clamping frame 101b. One side of the elastic clamping frame 101b has multiple elastic clamping plates, which are arranged in a ring. The radius after opening is larger than the radius of the mounting cylinder 101a, and is used to clamp and fix the insertion post 101d.

[0033] Specifically, the mounting component 101 also includes a hook 101c, a post 101d disposed on one side of the hook 101c, a mounting cylinder 101a disposed on one side of the post 101d, and a first channel 101e and a second channel 101f opened on the outside of the mounting cylinder 101a. The first channel 101e and the second channel 101f allow the first rotating handle 102c and the second rotating handle 201b to rotate within the channels. The hook 101c is used to lift the mold, and the mounting cylinder 101a is used to install the post 101d.

[0034] Furthermore, the lifting member 102 also includes a first rotating shaft 102b rotatably disposed on one side of the mounting cylinder 101a, a first rotating handle 102c disposed on the outside of the first rotating shaft 102b, and a top block 102d disposed on one side of the first rotating handle 102c. The top block 102d is used to lift and raise the lifting block 102a. The lifting member 102 also includes a toothed block 102e disposed on the outside of the lifting block 102a and a toothed groove 102f disposed on the inside of the elastic clamping frame 101b. The toothed block 102e extends into the toothed groove 102f. The toothed block 102e and the toothed groove 102f can make the contact between the lifting block 102a and one side of the elastic clamping frame 101b more dense, so that the lifting block 102a can better drive the elastic clamping frame 101b to slide out of the mounting cylinder 101a when it moves.

[0035] Operation process: Before installation, press down the first rotation, thereby driving the top block 102d to move. When the moving block moves, the toothed block 102e set on the outside of the lifting block 102a and the toothed groove 102f set on the inside of the elastic clamping frame 101b cause the lifting block 102a to squeeze the elastic clamping frame 101b, causing the elastic clamping frame 101b to extend out of the mounting cylinder 101a. Since one side of the elastic clamping frame 101b has multiple elastic clamping plates and they are arranged in a ring, after one side of the elastic clamping frame 101b extends out of the mounting cylinder 101a, it spreads outward. Then, the insertion post 101d to be installed is inserted into the elastic clamping frame 101b, and it is ready for quick fixing installation.

[0036] Example 2

[0037] Reference Figures 2-5 This is the second embodiment of the present invention. Unlike the previous embodiment, the back pressure member 201 includes a second rotating shaft 201a rotatably disposed inside the mounting cylinder 101a, a second rotating handle 201b rotatably disposed inside the second channel 101f, through holes 201c opened on both sides of the lifting block 102a, and an inner groove 201d opened inside the lifting block 102a. The radius of the through hole 201c is larger than the radius of the second rotating shaft 201a. The larger radius of the through hole 201c than the radius of the second rotating shaft 201a allows the lifting member 102a to move during the lifting and back pressure process without being jammed by the second rotating shaft 201a.

[0038] Specifically, the back pressure component 201 also includes a shaped back pressure block 201e disposed on the outside of the second rotating shaft 201a. The shaped back pressure block 201e is used to back pressure and reset the lifting component 102 after it moves. One side of the shaped back pressure block 201e is set as an arc-shaped part. The back pressure component 201 also includes a wedge-shaped surface 201f disposed on the outside of the elastic clamping frame 101b and a wedge-shaped notch 201g disposed on the side of the mounting cylinder 101a. The wedge-shaped surface 201f and the wedge-shaped notch 201g match each other. When the elastic clamping frame 101b is back pressured, during the process of the elastic clamping frame 101b retracting into the mounting cylinder 101a, multiple elastic clamping plates on its side wall are squeezed by the wedge-shaped notch 201g on the side wall of the mounting cylinder 101a due to the wedge-shaped surface 201f, which drives the multiple clamping plates to clamp inward, thereby realizing the rapid clamping and fixing of the insertion post 101d.

[0039] Furthermore, the reset component 202 includes a connecting plate 202a disposed inside the mounting cylinder 101a and a tension spring 202b disposed on one side of the connecting plate 202a. The two ends of the tension spring 202b are respectively connected to one side of the connecting plate 202a and one side of the elastic clamping frame 101b. The tension spring 202b is used to reset the component 102 after it is pushed back up.

[0040] The rest of the structure is the same as in Example 1.

[0041] Operation process: Before installation, press down the first rotation, thereby driving the top block 102d to move. When the moving block moves, the toothed block 102e set on the outside of the lifting block 102a and the toothed groove 102f set on the inside of the elastic clamping frame 101b cause the lifting block 102a to squeeze the elastic clamping frame 101b, causing the elastic clamping frame 101b to extend out of the mounting cylinder 101a. Since one side of the elastic clamping frame 101b has multiple elastic clamping plates and they are arranged in a ring, after one side of the elastic clamping frame 101b extends out of the mounting cylinder 101a, it spreads outward. Then, the insertion post 101d to be installed is inserted into the elastic clamping frame 101b.

[0042] When the lifting block 102a slides outward, the through hole 201c on the side wall of the lifting block 102a, near the lifting block 102a, contacts the second rotating shaft 201a. Simultaneously, the internal irregularly shaped back pressure block 201e is squeezed by one side of the inner groove 201d, causing it to rotate at a small angle. This causes the second rotating handle 201b to rotate slightly. When the insert post 101d needs to be quickly clamped and fixed after insertion, the second rotating handle 201b is pushed downwards. The downward movement of the second rotating handle 201b causes the internal irregularly shaped clamping block to rotate partially in the opposite direction. The lower arc-shaped part of the irregularly shaped clamping block presses against the side wall of the inner groove 201d, thereby causing... The moving jacking member 102 retracts inward, causing the side of the through hole 201c near the elastic clamping frame 101b to contact the second rotating shaft 201a, thereby driving the elastic clamping frame 101b to retract. During retraction, the tension spring 202b can be used to provide auxiliary reset force. During retraction, it is squeezed by the wedge-shaped notch 201g on the side wall of the mounting cylinder 101a, which drives multiple clamping plates to clamp inward, thereby achieving rapid clamping and fixing of the insert 101d, and finally achieving rapid clamping and fixing of the hook 101c. At the same time, when the jacking block 102a retracts, it presses the jacking block 102d in the opposite direction, driving the second rotating handle 201b to rotate in the opposite direction and reset.

[0043] Example 3

[0044] Reference Figures 1-8 This is the third embodiment of the present invention. Unlike the previous embodiments, this embodiment provides a tetrahedral template disassembly device, including the hook 101c replacement mechanism, a structural component 300 including a structural member 301 and a lifting member 302 disposed on one side of the structural member 301, a clamping component 400 including a fixing member 401 disposed on one side of the structural member 301 and a clamping member 402 disposed on one side of the lifting member 302, a rotating component 500 including a rotating member 501 disposed on one side of the lifting member 302 and a pressing member 502 disposed on one side of the clamping member 402, and the fixing member 401 including an annular plate 401b disposed within the fixing member 401.

[0045] Specifically, the structural component 301 includes a casting template 301a, a horizontal reinforcing bar 301b disposed on one side of the casting template 301a, and an adjustable hook 301c disposed on the outside of the horizontal reinforcing bar 301b. One end of the adjustable hook 301c is connected to the horizontal reinforcing bar 301b, and the other end is connected to the casting template 301a. The casting template 301a adopts a standardized integral steel template and is directly placed into the silo by a tank truck. The welded horizontal reinforcing bar 301b is used to connect with the adjustable hook 301c to prevent the template from floating during casting and to improve the stability of the casting template 301a during casting.

[0046] Furthermore, the lifting component 302 includes a mobile gantry crane 302a, a lifting device 302b slidably disposed on one side of the gantry crane, an installation plate 302c disposed on one side of the lifting device, a lifting rope 302d disposed on one side of the installation plate 302c, and a hook 101c disposed on one side of the casting template 301a. The mobile gantry crane 302a can move on the ground. The lifting device 302b is used to lift and dismantle the casting template 301a. The lifting device 302b can move laterally under the mobile gantry crane 302a. The installation plate 302c is used to install the clamping assembly 400. One end of the lifting rope 302d is connected to the installation plate 302c, and the other end is connected to the hook 101c on the side wall of the casting template 301a.

[0047] Preferably, the fixing member 401 includes a fixing cylinder 401a disposed on the upper side of the casting template 301a, an annular plate 401b disposed inside the fixing cylinder 401a, the fixing cylinder 401a being fixedly installed on the upper side of the casting template 301a, and the annular plate 401b being fixedly installed inside the fixing cylinder 401a. The clamping member 402 includes an mounting sleeve 402a disposed on one side of the extruder 502, an mounting tube 402b slidably disposed on one side of the extruder 502, and a clamping tube 402b rotatably disposed on the mounting sleeve 401a. The irregularly shaped pressure block 402d inside 2a and the through groove 402c opened on one side of the installation tube 402b. The two sides of the installation sleeve 402a are provided with slots that match the through groove 402c. One end of the irregularly shaped pressure block 402d extends out of the through groove 402c and the slot and contacts the annular plate 401b. The irregularly shaped pressure block 402d can extend out of the through groove 402c to quickly clamp and fix the annular plate 401b, thereby realizing the quick clamping and fixing of the casting template 301a.

[0048] Furthermore, the clamping member 402 includes a rotating shaft 402e disposed in the mounting sleeve 402a for driving the irregularly shaped pressure block 402d to rotate, an irregularly shaped pressure block 402d rotatably disposed outside the rotating shaft 402e for clamping the annular plate 401b, a through groove 402c opened outside the mounting tube 402b, and a mounting platform 402f disposed on one side of the mounting tube 402b. The irregularly shaped pressure block 402d can rotate around the rotating shaft 402e. One end of the irregularly shaped pressure block 402d extends out of the through groove 402c and the groove opening and contacts the annular plate 401b, and the other end is movably connected to the mounting platform 402f.

[0049] Preferably, the clamping member 402 further includes a return spring 402g disposed inside the mounting tube 402b and a fixing plate 402h disposed on one side of the mounting sleeve 402a. The two sides of the return spring 402g are respectively connected to the inner wall of the mounting tube 402b and the side wall of the fixing plate 402h. The return spring 402g is used to reset the mounting tube 402b.

[0050] Furthermore, the rotating component 501 includes a fixed tube 501a disposed on one side of the mounting tube 402b, a rotating plate 501b rotatably disposed on one side of the fixed tube 501a, a rotating block disposed on one side of the rotating plate 501b, and extrusion plates 501d disposed on both sides of the rotating block. The extrusion plates 501d are used to extrude the shaped tube 501e during rotation.

[0051] Specifically, the rotating component 501 includes a shaped tube 501e slidably disposed within the fixed tube 501a, an arc-shaped portion 501f disposed on one side of the shaped tube 501e, a groove portion 501g disposed on one side of the shaped tube 501e, and a vertical portion 501h disposed on one side of the shaped tube 501e. The extrusion plate 501d contacts one side of the shaped tube 501e. Two sets of arc-shaped portions 501f, groove portions 501g, and vertical portions 501h are provided and evenly distributed on one side of the shaped block. During the rotation of the rotating plate 501b, the rotating block is driven to rotate, thereby driving the extrusion plate 501d to move. The extrusion plate 501d first moves along the lowest point of the arc-shaped portion 501f to the highest point of the arc-shaped portion 501f. During the movement, it extrudes the shaped tube 501e, causing the shaped tube 501e to slide downward.

[0052] Furthermore, the rotating component 501 includes a rotating ring 501i disposed on one side of the rotating plate 501b, which facilitates the rotation of the rotating plate 501b. The extruding component 502 includes an extrusion tube 502a disposed on one side of the shaped tube 501e, a compression spring 502b sleeved on the outside of the extrusion tube 502a, and a fixing cover 502c disposed between the inner walls of the fixing tube 501a. The two ends of the compression spring 502b are respectively connected to the side wall of the fixing cover 502c and the side wall of the shaped tube 501e. The other end of the extrusion tube 502a extends into the mounting sleeve 402a and contacts one side of the mounting tube 402b. The extrusion tube 502a extends into the mounting sleeve 402a and slides therewith. When the arc plate rotates to the groove portion 501g, it enters the groove portion 501g, and the shaped tube 501e slides to the lowest point. The extrusion plate 501d enters the groove 501g and locks in place. The groove 501g is an arc-shaped groove. When the rotation continues, the extrusion plate 501d leaves the groove 501g and passes the vertical part 501h. If the rotation continues, the shaped tube 501e and the extrusion plate 501d separate from each other and are in a non-contact state. At this time, the compression spring 502b provides a restoring force to the shaped tube 501e, causing the shaped tube 501e to slide upward, so that the lowest point of the arc-shaped part 501f contacts the extrusion plate 501d again, and the rotation and extrusion on the next side are performed. When the shaped tube 501e moves, it drives the extrusion tube 502a to move. The extrusion tube 502a slides downward to extrude the mounting tube 402b, so that the shaped pressure block 402d extends out of the through groove 402c and clamps and fixes the annular plate 401b.

[0053] The rest of the structure is the same as in Example 2.

[0054] Operation process: After the hook 101c is fixedly installed, when it is necessary to quickly disassemble the casting template 301a, the installation sleeve 402a is inserted into the fixed sleeve 401a. The rotating plate 501b is rotated by the rotating ring 501i. During the rotation of the rotating plate 501b, the rotating block is driven to rotate, thereby driving the extrusion plate 501d to move. The extrusion plate 501d first moves from the lowest point of the arc-shaped part 501f to the highest point of the arc-shaped part 501f. During the movement, it extrudes the shaped tube 501e, causing the shaped tube 501e to slide downward. When the arc-shaped plate rotates to the groove part 501g, it enters the groove part 501g, and the shaped tube 501e slides to the lowest point. At this time, the extrusion plate 501d enters the arc part 501f and locks in place. 01g is designed with an arc-shaped groove. When the extrusion plate 501d leaves the groove 501g and passes the vertical part 501h, if the rotation continues, the shaped tube 501e and the extrusion plate 501d will separate from each other and be in a non-contact state. At this time, the compression spring 502b provides a restoring force to the shaped tube 501e, causing the shaped tube 501e to slide upward, so that the lowest point of the arc-shaped part 501f re-contacts the extrusion plate 501d, and the next side of the rotation extrusion is performed. When the shaped tube 501e moves, it drives the extrusion tube 502a to move. The extrusion tube 502a slides downward to extrude the mounting tube 402b, so that the shaped pressure block 402d extends out of the through groove 402c and clamps and fixes the annular plate 401b.

[0055] Then, after removing the adjustable hook 301c hanging on one side of the casting template 301a, start the lifting equipment 302b to lower the mounting plate 302c. When it is lowered above the casting template 301a, connect the lifting ropes 302d on both sides of the mounting plate 302c to the side wall hooks 101c of the casting template 301a. Then, insert the clamping member 402 on the upper side of the mounting plate 302c into the fixing member 401 set on the upper side of the casting template 301a, and rotate the rotating member 501 to quickly clamp and fix the fixing member 401. Then, start the lifting equipment 302b to quickly disassemble the casting template 301a.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
