Description

Technical Field

[0001] This utility model relates to the field of concrete pouring, specifically to a formwork for continuous pouring of vertical shafts. Background Technology

[0002] Currently, commonly used formwork for shaft construction includes slipform, wooden formwork, and modular formwork. Existing shaft casting formwork can be found in patent application number CN202121969079.0, which includes a main mold, a constriction mold, a cutting edge mold, a no-scraping template, and a demolding mechanism. The constriction mold, through sliding contact, connects to the hinged main mold to form a hollow cylinder with openings at the top and bottom, creating a casting space between the hollow cylinder, the no-scraping template, and the inner wall of the shaft. However, the aforementioned shaft casting formwork typically requires the erection of an operating platform or scaffolding inside the shaft, resulting in a large amount of preparation work and tedious demolding and assembly operations for workers. The operating platform or scaffolding also needs adaptive adjustments, leading to low efficiency in concrete pouring for the shaft's inner wall.

[0003] Therefore, how to improve the assembly and demolding efficiency of vertical shaft casting formwork is an urgent technical problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a continuous casting template for vertical shafts, thereby solving the technical problem of low assembly and demolding efficiency of existing vertical shaft casting templates.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a continuous casting template for vertical shafts, which includes:

[0007] A lifting assembly includes a connecting seat capable of vertical movement within a shaft, and the connecting seat being able to remain at any position along its movement trajectory; and

[0008] A forming assembly includes a plurality of side plates and a plurality of adjusting members that correspond one-to-one with each other. The plurality of side plates are arranged circumferentially along the connecting seat. One end of each adjusting member is connected to the connecting seat, and the other end is connected to the side plate. The adjusting member has a first state of moving the side plate away from the connecting seat and a second state of moving the side plate closer to the connecting seat. When the adjusting member is in the first state, the plurality of side plates surround each other to form a forming surface.

[0009] In some embodiments, the adjusting member includes a first telescopic member and a second telescopic member with adjustable length. One end of the first telescopic member is fixed to the connecting seat, and the other end is hinged to the side plate. The two ends of the second telescopic member are respectively hinged to the connecting seat and the side plate.

[0010] In some embodiments, the first telescopic member includes a first hydraulic cylinder, the cylinder body of which is mounted on the connecting seat, and the piston rod of which is hinged to the side plate.

[0011] In some embodiments, the second telescopic member includes a second hydraulic cylinder, the cylinder body of which is hinged to the connecting seat, and the piston rod of which is hinged to the side plate.

[0012] In some embodiments, the lifting assembly includes a support frame, a take-up roller, a drive unit, and a traction rope. The support frame is erected above the shaft, the take-up roller is rotatably mounted on the support frame, one end of the traction rope is connected to and wound around the take-up roller, the other end of the traction rope is connected to the connecting seat, and the drive unit is driven to rotate the take-up roller.

[0013] In some embodiments, the top of the connector has a winding hole, and the traction rope is tied to the winding hole.

[0014] In some embodiments, the drive element includes a motor mounted on the support frame and drivenly connected to the take-up roller.

[0015] In some embodiments, the vertical shaft continuous casting template further includes a plurality of positioning components corresponding one-to-one with the plurality of side plates, one end of the positioning component being connected to the top of the side plate, and the other end being detachably connected to the vertical shaft rock wall.

[0016] In some embodiments, the positioning component includes a third telescopic member, the length of which is adjustable, and one end of which is hinged to the top of the side plate, while the other end is detachably connected to the shaft wall.

[0017] In some embodiments, guide wedge surfaces are provided at both ends of the side plate.

[0018] Compared with the prior art, the vertical shaft continuous casting formwork provided by this utility model has the following advantages:

[0019] First, adjust the lifting assembly, using the connecting seat to move each side plate and adjusting component to the bottom of the shaft. Then, switch each adjusting component from its second state to its first state, causing the side plates to move away from the connecting seat and close together to form a shaping surface. A pouring area is then formed between the shaping surface and the shaft wall, and concrete is poured within this area. After the concrete solidifies, the adjusting components can be switched back to their second state, causing the side plates to detach from the solidified concrete. Using the lifting assembly connecting seat, the connecting seat moves each side plate and adjusting component upwards as a whole. Once at the predetermined position, the adjusting components can be switched back to their first state again, and the side plates close together to form the shaping surface once more, allowing for the next stage of concrete pouring. Using this continuous shaft pouring formwork, the assembly and demolding of the continuous shaft pouring formwork can be quickly completed by switching the adjusting component states and adjusting the connecting seat positions, thus improving the construction speed of shaft pouring.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] To address the technical problem of low assembly and demolding efficiency in vertical shaft casting formwork, this utility model provides a continuous casting formwork for vertical shafts, which can move the mold as a whole in the vertical direction and allow each formwork to move radially, thereby improving the assembly and demolding speed of the formwork.

[0025] It should be noted that the continuous casting template for vertical shafts of this utility model is used for casting the inner wall of vertical shafts, etc. For ease of explanation, this utility model will only be described using the application of the continuous casting template for vertical shafts to the inner wall of vertical shafts as an example.

[0026] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of a continuous casting template for a vertical shaft in one embodiment of the present invention. The continuous casting template for a vertical shaft includes a lifting assembly 100 and a forming assembly 200. The lifting assembly 100 includes a connecting seat 110 that can move vertically within the vertical shaft, and the connecting seat 110 can stop at any position on its movement trajectory. The forming assembly 200 includes a plurality of side plates 210 and a plurality of adjusting members 220 that correspond one-to-one with each other. The plurality of side plates 210 are arranged circumferentially along the connecting seat 110. One end of the adjusting member 220 is connected to the connecting seat 110, and the other end is connected to the side plate 210. The adjusting member 220 has a first state of driving the side plate 210 away from the connecting seat 110, and a second state of driving the side plate 210 closer to the connecting seat 110. When the adjusting member 220 is in the first state, the plurality of side plates 210 surround and form a forming surface. By using the aforementioned continuous casting formwork for vertical shafts, the assembly and demolding of the continuous casting formwork for vertical shafts can be completed quickly by switching the state of the adjustment component 220 and adjusting the position of the connecting seat 110, thereby improving the construction speed of vertical shaft casting.

[0027] First, adjust the lifting assembly 100, using the connecting seat 110 to move each side plate 210 and each adjusting component 220 to the bottom of the shaft. Then, switch each adjusting component 220 from the second state to the first state, so that each side plate 210 moves away from the connecting seat 110 and closes to form a forming surface. Subsequently, a pouring area can be formed between the forming surface and the shaft wall, and concrete can be poured in the pouring area. After the concrete solidifies, the adjusting component 220 can be switched to the second state, thereby causing the side plate 210 to detach from the solidified concrete. Using the lifting assembly 100 connecting seat 110, the connecting seat 110 moves each side plate 210 and each adjusting component 220 upward as a whole. After reaching the predetermined position, the adjusting component 220 can be switched from the second state to the first state again, and the side plates 210 close to form a forming surface again, thus proceeding to the next stage of concrete pouring. By using the aforementioned continuous casting formwork for vertical shafts, the assembly and demolding of the continuous casting formwork for vertical shafts can be completed quickly by switching the state of the adjustment component 220 and adjusting the position of the connecting seat 110, thereby improving the construction speed of vertical shaft casting.

[0028] In some embodiments, the adjusting member 220 includes a first telescopic member 221 and a second telescopic member 222 with adjustable length. One end of the first telescopic member 221 is fixed to the connecting seat 110, and the other end is hinged to the side plate 210. The two ends of the second telescopic member 222 are respectively hinged to the connecting seat 110 and the side plate 210. The first telescopic member 221 and the second telescopic member 222 jointly drive the side plate 210 to move relative to the connecting seat 110. As the side plate 210 moves closer to or away from the connecting seat 110, it can also drive the side plate 210 to flip, so as to prevent adjacent side plates 210 from jamming each other when the side plate 210 moves closer to the connecting seat 110.

[0029] Based on the above embodiments, in some embodiments, the first telescopic member 221 includes a first hydraulic cylinder, the cylinder body of which is mounted on the connecting seat 110, and the piston rod of the first hydraulic cylinder is hinged to the side plate 210. The length of the first telescopic member 221 can be adjusted by moving the piston rod relative to the cylinder body of the first hydraulic cylinder.

[0030] Based on the above embodiments, in some embodiments, the second telescopic member 222 includes a second hydraulic cylinder, the cylinder body of which is hinged to the connecting seat 110, and the piston rod of which is hinged to the side plate 210. Movement of the piston rod relative to the cylinder body of the second hydraulic cylinder can adjust the length of the second telescopic member 222.

[0031] Any implementation of the lifting assembly 100 that can drive the connecting seat 110 to move vertically is feasible. In some embodiments, the lifting assembly 100 includes a support frame 120, a take-up roller 130, a drive member 140, and a traction rope 150. The support frame 120 is erected above the shaft, the take-up roller 130 is rotatably mounted on the support frame 120, one end of the traction rope 150 is connected to and wound around the take-up roller 130, and the other end of the traction rope 150 is connected to the connecting seat 110. The drive member 140 drives the take-up roller 130 to rotate. When the take-up roller 130 rotates clockwise to wind up the traction rope 150, it can pull the connecting seat 110 upward. Conversely, when the take-up roller 130 rotates counterclockwise to release the traction rope 150, the connecting seat 110 will descend under the action of gravity.

[0032] Based on the above embodiments, in some embodiments, the top of the connecting seat 110 is provided with a winding hole 111, and the traction rope 150 is tied to the winding hole 111, so that the traction rope 150 can be more securely connected to the connecting seat 110.

[0033] Any implementation of the drive component 140 that can drive the take-up roller 130 to rotate is feasible. In some embodiments, the drive component 140 includes a motor, which is mounted on the support frame 120 and is connected to the take-up roller 130 in a transmission connection.

[0034] In some embodiments, the continuous casting formwork for the shaft also includes a plurality of positioning components 300 corresponding one-to-one with a plurality of side plates 210. One end of each positioning component 300 is connected to the top of the side plate 210, and the other end is detachably connected to the shaft wall. Since the positioning components 300 connect the side plates 210 and the rock wall, they help to maintain the stability of the side plates 210.

[0035] In some embodiments, the positioning assembly 300 includes a third telescopic member 310, the length of which is adjustable. One end of the third telescopic member 310 is hinged to the top of the side plate 210, and the other end is detachably connected to the shaft wall. Since the shape of the shaft wall is not regular, the distance between the side plate 210 and the shaft wall varies. By connecting the side plate 210 and the shaft wall with the adjustable-length third telescopic member 310, the varying distance between the side plate 210 and the shaft wall can be accommodated.

[0036] In some embodiments, guide wedge surfaces are provided at both ends of the side plate 210. The guide wedge surfaces of adjacent side plates 210 can overlap each other, thereby improving the sealing performance between adjacent side plates 210.

[0037] To better understand this utility model, the following is combined with... Figures 1 to 2 The technical solution of this utility model is described in detail below:

[0038] The drive unit 140 drives the take-up roller 130 to rotate. When the take-up roller 130 reverses to release the traction rope 150, the connecting seat 110 descends to the bottom of the shaft under the action of gravity. The first telescopic member 221 and the second telescopic member 222 jointly drive the side plates 210 to move relative to the connecting seat 110, so that each side plate 210 moves away from the connecting seat 110 and closes to form a forming surface. Then, a pouring area is formed between the forming surface and the shaft wall, and concrete is poured in the pouring area. After the concrete solidifies, the first telescopic member 221 and the second telescopic member 222 jointly drive the side plates 210 to move relative to the connecting seat 110 and cause the side plates 210 to flip, preventing adjacent side plates 210 from getting stuck together as they approach the connecting seat 110. This allows the side plates 210 to detach from the solidified concrete. Then, the drive unit 140 drives the take-up roller 130 to rotate forward, thereby winding the traction rope 150 and pulling the connecting seat 110 upward. Upon reaching the designated position, the side plates 210 are used again to enclose and form the shaped surface, thus enabling the next stage of concrete pouring. Using the aforementioned continuous casting formwork for the vertical shaft, the assembly and demolding of the continuous casting formwork for the vertical shaft can be quickly completed by switching the state of the adjusting component 220 and adjusting the position of the connecting seat 110, thereby improving the construction speed of the vertical shaft pouring.
