[0076] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. It should be noted that, for ease of description, in this application, "left side" is referred to as "first end", "right side" as "second end", "upper side" as "first end", and "lower side" as "second end" in the current view. The purpose of such description is to clearly express the technical solution and should not be construed as an improper limitation of the technical solution of this application.
[0077] This invention aims to address the technical problem of the lack of a method for dismantling large-volume, large-area construction formwork in existing technologies. Please refer to [link / reference needed]. Figure 1-7As shown, this technical solution is mainly used for the dismantling of large-volume, large-module templates. Specifically, the template dismantling equipment based on hydraulic means in this solution is equipped with a working base 10, which is arranged on one side of the template 1 to be dismantled. The template 1 to be dismantled can be inclined or vertical. The characteristics of this type of template are that it is relatively large in volume, and sufficient safety needs to be ensured. In addition, the dismantling pulling force needs to be more flexible and stable. First, this technical solution sets up a hydraulic jacking mechanism 100, which is set on the working base 10. Unlike a jack, the hydraulic jacking mechanism 100 in this technical solution includes a... A hydraulic cylinder 101 is used. The first hydraulic cylinder 101 moves horizontally to raise a lifting plate 102 by a preset distance and lift the lower edge of the template 1 to be dismantled. The lifting method using a jack is not adopted. The main reason is that although the template is large, excessive lifting pressure during actual dismantling will cause force accumulation and serious damage during dismantling. On the other hand, the lifting method using a jack has high requirements for the foundation support surface and is easy to damage the foundation support surface, which poses a safety hazard. Therefore, this technical solution needs to provide a more stable lifting force to complete the dismantling. Therefore, the horizontal movement of the first hydraulic cylinder 101 is used to convert the lifting force.
[0078] Furthermore, a reciprocating traction mechanism 200 was designed, which is mounted on top of a support 30. The reciprocating traction mechanism 200 includes a second hydraulic component 201. The reciprocating motion of the second hydraulic component 201 enables the traction end of the second hydraulic component 201 to move along a virtual elliptical trajectory. The second hydraulic component 201 is connected to the upper edge of the template 1 to be dismantled via a pull rope 20. In this way, the force that can be applied during dismantling is variable and has a gradual effect, which is more conducive to dismantling than continuous tension dismantling, which would cause damage to the template injection components.
[0079] Additionally, the intermediate traction assembly 300 is arranged on a platform 40 below the reciprocating traction mechanism 200, and the platform 40 is mounted on the support 30; the intermediate traction assembly 300 includes an intermediate traction end 3011, which is used to connect to and traction the side of the template 1 to be demolished via another pull rope 20; as the main implementation of the demolition force.
[0080] Therefore, the advantage of this technical solution is that the lifting force provided by the hydraulic jacking mechanism 100 is more stable, the traction force of the reciprocating traction mechanism 200 has a gradual effect to prevent continuous pulling from damaging the template components, and the intermediate traction component 300 ensures the stability of the traction force. The above three can cooperate with each other when they operate, and it can be applied to the dismantling of large templates.
[0081] In one specific embodiment, please refer to Figure 1 , 2As shown, multiple U-shaped connectors 11 can be prefabricated and fixed on the side of the template 1 to be dismantled; a strip-shaped notch 12 is cut out at the bottom of the template 1 to be dismantled.
[0082] An opening groove 102a is formed on the other side of the lifting plate 102; the lifting plate 102 can be inserted into the strip-shaped notch 12.
[0083] In one specific embodiment, please refer to Figure 1 , 2 As shown in Figures 4 and 5, the hydraulic lifting mechanism 100 includes:
[0084] Two sets of symmetrically arranged fixing blocks 110; each set of fixing blocks 110 is connected to a threaded component 111;
[0085] Threaded component 111 includes:
[0086] The threaded end 111a is screwed onto a threaded post 112; the threaded post 112 includes two sets and is fixedly connected to one side of the lifting plate 102.
[0087] The threaded component 111 further includes: a rotating shaft end 111b, which is connected to the second end of the threaded end 111a; each rotating shaft end 111b is rotatably connected to a fixing block 110; the second end of the rotating shaft end 111b extends out of the fixing block 110 and is connected to a rotating shaft arm 113; the rotating shaft arm 113 is perpendicular to the rotating shaft end 111b; each fixing block 110 is connected to the working base 10 through a connecting plate 110a.
[0088] In one specific embodiment, please refer to Figure 1 , 2 As shown in Figures 4, 5, and 6, the fixed end of the first hydraulic cylinder 101 is provided with a first rotating connection part 101a; the output end of the first hydraulic cylinder 101 is provided with a second rotating connection part 101b; the first rotating connection part 101a is rotatably connected to a rotating shaft arm 113; and the second rotating connection part 101b is rotatably connected to another rotating shaft arm 113.
[0089] As can be seen from the above configuration, when the hydraulic lifting mechanism 100 is working, as shown in the attached... Figure 4 As shown, the retraction action of the first hydraulic cylinder 101 causes the two rotating shaft arms 113 to rotate, while the opposing fixed block 110 is connected to the working base 10 and remains stationary. At this time, the action of the threaded part 111 causes the lifting plate 102 to be raised a small distance. The lifting plate 102 can be inserted into the strip notch 12. The small-distance lifting action is completed through the above principle. The opening slot 102a of the lifting plate 102 is used to arrange some filler materials, which play a role in anti-slip and shock absorption.
[0090] In one specific embodiment, please refer to Figure 1 , 2As shown in Figure 3, the second hydraulic component 201 includes: a hydraulic cylinder 201a fixed to the support platform 301 of the bracket 30, with the first end of the hydraulic cylinder 201a open;

[0092] Additionally, in one specific embodiment, please refer to Figure 1 , 2 As shown in Figures 3 and 7, the reciprocating traction mechanism 200 further includes a balancing action mechanism, which is connected to the traction end 202a and used to balance the pressure generated when the traction end 202a reciprocates with the piston rod 202; the balancing action mechanism includes two sets of balancing arm assemblies 210; each set of balancing arm assembly 210 includes a connecting arm 211, the first end of which is connected to the side of the traction end 202a, and the two sets of connecting arms 211 form a 45-degree angle with the traction end 202a as the vertex;
[0093] Each set of connecting arms 211 is connected to a rotating part 213 via a connecting piece 212; the rotating part 213 is connected to a rotating seat 215 via a rotating shaft 214; the rotating seat 215 is connected to the support platform 301. This design serves two purposes: firstly, the force on the traction end 202a is balanced by the connecting arms 211, resulting in a more uniform force distribution. In particular, the traction end 202a at the end of the piston rod 202 will oscillate in an elliptical trajectory under the action of the piston, and the connecting arms 211 ensure the stability of this motion; secondly, it ensures the overall stability of the reciprocating traction mechanism 200.
[0094] In one specific embodiment, please refer to Figure 1 , 2 As shown, the intermediate traction assembly 300 includes:
[0095] The first main cylinder 310 has its fixed end rotatably connected to a fixed seat 311, which is fixed on the platform 40.

The auxiliary cylinder 320 has its fixed end fixed on the platform 40 and located on one side of the first main cylinder 310. The output end of the auxiliary cylinder 320 is rotatably connected to an actuating shaft seat 321, which is fixedly connected to the radial direction of the first main cylinder 310.
[0096] The dismantling method using the hydraulically based template dismantling equipment includes the following steps:
[0097] Step S1: First, use hoisting machinery to hoist and connect one or more sets of U-shaped connectors 11 connected to the template 1 to be dismantled, so as to ensure the safety of the overall dismantling.
