[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 6 As shown, this embodiment provides a template lifting device, including a template structure and a frame structure. The template structure includes two template components 1, each of which is formed by connecting multiple templates 11 end to end. The two template components 1 are arranged sequentially in the vertical direction, and their cavities are connected. Magnetic suction components are provided at both ends of the two template components 1 in the vertical direction to magnetically connect them, ensuring the connection stability of the two template components 1 in the vertical direction. The frame structure includes a frame body 2, a fixing component 3, and a moving component 4. The frame body 2 is located outside the template components 1, the fixing component 3 is located on the frame body 2, and the moving component 4 is movably located on the frame body 2 in the vertical direction. The fixing component 3 is detachably connected to the upper template component 1, and the moving component 4 is detachably connected to the multiple templates 11 of the lower template component 1. After the concrete in the cavity of the lower template component 1 is poured and formed, the moving component 4 can be used to move the multiple templates 11 of the lower component upwards to be located above the original upper template component 1. In practice, the moving component 4 first moves the multiple templates 11 of the lower template component 1 horizontally to demold the template component 1. Then, the moving component 4 moves the multiple templates 11 of the lower template component 1 upward. During this process, the fixing component 3 connects to the original upper template component 1 to ensure the stability of the upper template component 1 and the frame 2. That is, this template lifting device can use the vertical movement of the moving component 4 on the frame 2 to lift the lower template component 1, while the fixing component 3 on the frame 2 can fix the upper template component 1. This effectively improves the problem of swaying and displacement of the template 11 during the lifting process, improves construction accuracy, and ensures construction safety.

[0039] Optionally, such as Figure 2As shown, the template assembly 1 also includes multiple fixing plates 12, multiple limiting members 13, and multiple stops 14. Multiple templates 11 are connected end to end to form a template assembly 1. Magnetic members 15 are provided at both ends of the multiple templates 11 in the vertical direction to ensure that even if the order of two template assemblies 1 is changed in the vertical direction, the two template assemblies 1 can still be connected by magnetic attraction. In this embodiment, a fixing plate 12 is disposed on one template 11, a limiting member 13 is detachably connected to the fixing plates 12 on two adjacent templates 11, and the stops 14 are connected to the limiting members 13 and sandwiched between two adjacent templates 11. In this embodiment, the template 11 is a flat plate structure, and multiple templates 11 surround a rectangular mold cavity. Four templates 11 can be connected end to end in sequence to form a template assembly 1, and each limiting member 13 is located at the corner of the template assembly 1 to connect two adjacent templates 11. Because the template 11 is a flat structure, a narrow space with the thickness of the template 11 as the side length is formed at the corner of two adjacent templates 11. The stop block 14 is placed in this narrow space, and the connector 41 is located on the side of the stop block 14 away from the template 11. The connector 41 is connected to the template 11, so that the stop block 14 can be fixed and the connection between adjacent templates 11 can be sealed by the stop block 14, thereby ensuring the sealing of the mold cavity and preventing the formation of gaps at the connection between two adjacent templates 11, which would affect the concrete pouring.

[0040] Optionally, such as Figure 2 As shown, a template assembly 1 has two sets of fixing plates 12, two sets of limiting members 13, and one set of stops 14. The two sets of fixing plates 12 and the two sets of limiting members 13 are all vertically spaced on the template 11, while the stops 14 are at the same vertical height as the template 11, and both ends of the stops 14 are connected to one set of limiting members 13 respectively. In this embodiment, a template assembly 1 has four templates 11, which form a rectangular mold cavity. The set of fixing plates 12 has four fixing plates 12, and two fixing plates 12 are vertically spaced on one template 11. The set of limiting members 13 has four limiting members 13. Adjacent templates 11 are connected by two vertically spaced limiting members 13, thereby ensuring the connection stability of multiple templates 11.

[0041] In this embodiment, the fixing plate 12 has a C-shaped structure and is disposed on the template 11 with the groove of the C-shaped structure facing away from the template 11. The limiting member 13 has an L-shaped structure, with both ends of the limiting member 13 inserted into the grooves of two adjacent fixing plates 12. The fixing plate 12 and the limiting member 13 are connected by fasteners. The fixing plate 12 is provided with a first mounting hole, and the two ends of the limiting member 13 are provided with second mounting holes. The fasteners pass through the first mounting holes and the second mounting holes to connect the fixing plate 12 and the limiting member 13. The stop block 14 is located between two adjacent templates 11 and the limiting member 13. Therefore, when the limiting member 13 is fixed to the fixing plate 12, the stop block 14 will be fixed between the two templates 11 and the limiting member 13.

[0042] Optionally, such as Figure 1 and Figure 2 As shown, the movable component 4 has two sets, one set of movable components 4 is connected to the fixed plate 12 of the template component 1. The movable components 4 are arranged vertically at intervals on the frame 2, while the fixed plates 12 are arranged vertically at intervals on the template 11, and in the height direction of the template 11, the two sets of fixed plates 12 are respectively arranged at both ends of the template 11.

[0043] Optionally, such as Figures 2 to 4 As shown, the moving component 4 includes a connector 41, a telescopic component 42, and a slider 44. One end of the connector 41 is detachably connected to the fixing plate 12 of the template component 1, and the other end of the connector 41 is provided with the telescopic component 42. The telescopic component 42 can extend and retract in the horizontal direction to drive the connector 41 to move back and forth in the horizontal direction. The end of the telescopic component 42 that is not connected to the connector 41 is connected to the slider 44. The slider 44 is sleeved on the screw 23. The screw 23 is installed in the guide groove on the frame 2. The slider 44 is located in the guide groove. The guide groove extends in the vertical direction and limits the slider 44 to move only in the vertical direction on the screw 23. Therefore, the rotation of the screw 23 can drive the slider 44 to move.

[0044] In practice, the connection between the limiting member 13 and the fixing plate 12 can be released first, so that one template assembly 1 can be split into multiple individual templates 11. Then, the telescopic member 42 is retracted to move the connecting member 41 toward the slider 44, thereby moving the template 11 connected to the connecting member 41 toward the slider 44. Once all templates 11 have detached from the poured concrete and moved to the first position, the screw 23 can be driven to rotate, causing the slider 44 to move upward, thereby moving the lower template 11 upward until the upper template 11 is above the lower template 11. The first position is the position where the lower template 11 will not interfere with the upper template 11 when it moves upward. Then, the telescopic member 42 is extended to move the connecting member 41 away from the slider 44, thereby moving the template 11 connected to the connecting member 41 away from the slider 44 and moving it to the second position. In the second position, the edges of multiple templates 11 abut against each other. At this point, the multiple templates 11 can be connected to the limiting member 13 via the fixing plate 12, thereby allowing the multiple templates 11 to recombine to form a template assembly 1 with a mold cavity for subsequent concrete pouring. In this manner, the lower template 11 can always be slid above the upper template 11 to form a new mold cavity.

[0045] In this embodiment, the frame 2 includes multiple uprights 21 and multiple horizontal bars 22. The uprights 21 are vertically arranged, and the horizontal bars 22 are horizontally arranged. The uprights 21 and horizontal bars 22 are connected to form the frame 2. Figure 1 As shown, in this embodiment, the template component 1 has a rectangular structure, and the moving component 4 is disposed on the frame 2 and detachably connected to the template 11. The fixing component 3 is disposed on the frame 2 and detachably connected to the connection point of two adjacent templates 11. To avoid interference between the moving component 4 and the fixing component 3, the frame 2 has an octagonal structure, and the moving component 4 and the fixing component 3 are spaced apart in the circumference of the frame 2. Optionally, a guide groove extending in the vertical direction is disposed on the column 21, the screw 23 is vertically disposed in the guide groove, the slider 44 is sleeved on the screw 23 and slidably disposed in the guide groove, and a motor 24 is also disposed in the guide groove. The motor 24 is connected to the end of the screw 23 to drive the screw 23 to rotate around its own axis, thereby driving the slider 44 to move in the vertical direction.

[0046] In this embodiment, the fixing plate 12 has a C-shaped structure, and one end of the connector 41 is inserted into the groove of the C-shaped structure. The fixing plate 12 is provided with a third mounting hole, and the connector 41 is provided with a fourth mounting hole. Fasteners pass through the third mounting hole and the fourth mounting hole to connect the fixing plate 12 and the connector 41. The connector 41 and the fixing plate 12 are detachably connected. That is, when it is necessary to move a certain template component 1 upward, the connector 41 is connected to the fixing plate 12 of that template component 1, while the fixing component 3 is connected to the fixing plate 12 of another template component 1. The fixing component 3 and the moving component 4 are never connected to the same template component 1 at the same time.

[0047] Optionally, such as Figure 2 and Figure 3 As shown, the moving component 4 also includes a limiting chamber 43, with a telescopic member 42 disposed within the limiting chamber 43. The connecting member 41 and the slider 44 both extend into the limiting chamber 43 and connect to the telescopic member 42. The limiting chamber 43 is a cylindrical structure with both ends open. The telescopic member 42, disposed within the limiting chamber 43 and connected to the connecting member 41 and the slider 44, improves the horizontal alignment of the three components, preventing the moving component 4 from shifting during extension and retraction. In this embodiment, the telescopic member 42 is a bidirectional hydraulic cylinder, capable of reciprocatingly pushing the connecting member 41 to move the template 11 horizontally.

[0048] Furthermore, such as Figure 1 and Figure 5 As shown, the fixing components 3 have two sets, one set of fixing components 3 is connected to the limiting members 13 of the template components 1. The fixing components 3 are arranged vertically at intervals on the frame 2, while the limiting members 13 are arranged vertically at intervals on the template 11, and in the height direction of the template 11, the two sets of limiting members 13 are respectively arranged at both ends of the template 11.

[0049] Optionally, such as Figure 5 and Figure 6 As shown, the fixing component 3 includes an insert plate 31. A through groove is provided on the frame 2, and a fixing groove is provided on the fixing plate 12 of the template component 1. The insert plate 31 is inserted into the through groove and the fixing groove and is detachably connected to the frame 2. In specific implementation, if it is necessary to lift the lower template 11, the upper template component 1 also needs to be fixed. In this case, the insert plate 31 can be inserted into the fixing groove of the upper template component 1 and the through groove corresponding to the fixing groove in the horizontal direction. Then, the insert plate 31 is connected to the frame 2 so that the insert plate 31 is fixed in the through groove and the fixing groove, thereby achieving relative fixation between the upper template component 1 and the frame 2. When it is necessary to lift the template 11 again, the insert plate 31 needs to be removed, that is, the relative fixation between the template component 1 and the frame 2 is released, and instead, it is connected to the frame 2 via the moving component 4.

[0050] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
