A U-shaped channel concrete lining mold

Abstract

This utility model relates to the field of concrete pouring technology, specifically a U-shaped channel concrete lining mold, including an inner chamber. An auxiliary mechanism is provided on the surface of the inner chamber, including a lifting component disposed inside the inner chamber. The lifting component includes multiple top plates, with sliding rods symmetrically fixedly installed on the lower surface of each top plate. A trapezoidal block is fixedly installed at the lower end of each sliding rod, and trapezoidal push blocks are symmetrically and movably arranged on both sides of each trapezoidal block. Two transmission components are respectively disposed on one side of each of the two side plates. In this utility model, by flipping the side plates, the pressing blocks are moved, causing the sliding rods to drive the trapezoidal push blocks to move. The pressing trapezoidal blocks move upward, causing the top plates to push the concrete channel on the surface of the inner chamber upward a certain distance. Thus, when the side plates are opened, the force of the opening of the side plates first lifts the concrete channel a certain distance, facilitating the hoisting rope to pass under the concrete for lifting and transportation, making it easier to remove the concrete channel from the mold.

Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, specifically a U-shaped channel concrete lining mold. Background Technology

[0002] Concrete channels have been widely used in the construction of farmland irrigation canals. Their main advantages are that they greatly improve construction efficiency, reduce labor intensity and construction costs. Most concrete channels are U-shaped structures, including monolithic and modular types.

[0003] After the existing U-shaped concrete channel is poured, the concrete is usually exposed by flipping open the side baffles and then lifted out with the help of lifting equipment. However, the inner wall of the concrete channel is close to the inner cavity of the mold, so the concrete channel needs to be lifted manually first, and the lifting rope of the lifting equipment needs to be passed through the inside of the channel before lifting. It is not convenient to directly pass the lifting rope under the concrete for lifting and transportation after the baffles are opened, which is quite inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a U-shaped channel concrete lining mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A U-shaped channel concrete lining mold includes an inner chamber, with side plates at both ends and baffles hinged to both sides of the inner chamber. An auxiliary mechanism is provided on the surface of the inner chamber, the auxiliary mechanism including:

[0007] A lifting assembly is installed inside the inner compartment. The lifting assembly includes multiple top plates. Slide rods are symmetrically fixedly installed on the lower surface of the top plates. Trapezoidal blocks are fixedly installed at the lower ends of the slide rods. Trapezoidal push blocks are symmetrically and movably arranged on both sides of the trapezoidal blocks.

[0008] Two transmission components are respectively located on one side of the two side plates.

[0009] Furthermore, the upper surface of the inner compartment is provided with multiple storage slots, the top plate is movably connected to the storage slots at the corresponding positions, the sliding rod slides through the inner compartment, and a support frame is fixedly installed on the lower surface of the inner compartment.

[0010] Furthermore, the lower surface of the inner compartment is provided with a sliding groove, and two sliding strips are slidably connected inside the fixing frame, with the sliding strips passing through the sliding groove and being fixedly connected to the trapezoidal push block at the corresponding position.

[0011] Preferably, a compression block is fixedly installed at the other end of the slide bar.

[0012] Furthermore, the transmission assembly includes:

[0013] Two fixing sleeves are respectively fixedly installed on one side surface of the two baffles;

[0014] Two threaded sleeves are rotatably connected to the inside of two fixed sleeves via bearings;

[0015] A two-way screw, screwed into the inside of two threaded sleeves.

[0016] Preferably, a slide rail is symmetrically fixedly installed on one side surface of the side plate, and a sliding connecting seat is slidably connected inside the slide rail, with the bidirectional screw rotating through the sliding connecting seat.

[0017] Preferably, a limit ring is fixedly installed on the outer surface of the bidirectional screw inside the sliding connection seat, and hexagonal nuts are fixedly installed at both ends of the bidirectional screw.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By turning two double-acting screws, the threaded sleeve rotates as the position moves, which facilitates the flipping of the baffle and provides power for the flipping of the baffle. At the same time, it restricts the position of the baffle and prevents the gravity of the concrete channel from squeezing the top plate downward and resetting it.

[0020] 2. When the baffle flips to both sides, the baffle presses down on the squeezing block, causing the two trapezoidal push blocks to move inward. The squeezing trapezoidal block moves upward, causing the top plate to move upward. Thus, through the force of the baffle opening, the top plate pushes the concrete channel on the inner surface of the chamber upward by a certain distance, raising the concrete channel by a certain distance first, making it easier for the hoisting rope to pass under the concrete for hoisting and transportation, and making it easier to remove the concrete channel from the mold.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 In this embodiment of the utility model, a U-shaped channel concrete lining mold includes an inner chamber 1, with side plates 101 at both ends of the inner chamber 1 and baffles 102 hinged to both sides of the inner chamber 1. An auxiliary mechanism is provided on the surface of the inner chamber 1. The auxiliary mechanism includes a lifting component 2 disposed inside the inner chamber 1. The lifting component 2 includes multiple top plates 201. A sliding rod 202 is symmetrically fixedly installed on the lower surface of the top plate 201. A trapezoidal block 203 is fixedly installed at the lower end of the sliding rod 202. Trapezoidal push blocks 207 are symmetrically and movably disposed on both sides of the trapezoidal block 203. Two transmission components 3 are respectively disposed on one side of the two side plates 101.

[0029] Specifically, the transmission component 3 provides power for the flipping of the two baffles 102, while restricting the position of the baffles 102. When the baffles 102 flip, they drive the lifting component 2 to operate, causing the top plate 201 to move upward and lift the concrete channel upward.

[0030] Example 1

[0031] like Figure 2-4 As shown, in this embodiment, the upper surface of the inner chamber 1 is provided with multiple storage slots 105, the top plate 201 is movably inserted into the storage slots 105 at the corresponding positions, the slide bar 202 slides through the inner chamber 1, and a support frame 103 is fixedly installed on the lower surface of the inner chamber 1. The support frame 103 raises the mold as a whole to a certain height, which facilitates the movement of the slide bar 205.

[0032] In this embodiment, the storage slot 105 stores the top plate 201, so that the upper surface of the top plate 201 and the upper surface of the inner compartment 1 form a plane. When the top plate 201 moves up and down, the stability of the top plate 201 is improved by the sliding limit of the slide rod 202 and the inner compartment 1.

[0033] like Figure 3 and Figure 4 As shown, in this embodiment, a groove 104 is provided on the lower surface of the inner compartment 1, and two slide bars 205 are slidably connected inside the fixing frame 204. The slide bars 205 pass through the groove 104 and are fixedly connected to the trapezoidal push block 207 at the corresponding position. A pressing block 206 is fixedly installed at the other end of the slide bar 205.

[0034] In specific implementation, when the baffle 102 flips to both sides, the baffle 102 presses down on the extrusion block 206, causing the extrusion block 206 to drive the slide bar 205 to slide inside the fixed frame 204. Through the sliding limit of the slide groove 104 and the slide bar 205, the two trapezoidal push blocks 207 move inward, and the extrusion trapezoidal block 203 moves upward, causing the top plate 201 to move upward. Thus, through the force of the baffle 102 opening, the top plate 201 pushes the concrete channel on the surface of the inner chamber 1 to move upward by one distance, so that the concrete channel is first raised a certain distance, making it easier for the hoisting rope to pass under the concrete for hoisting and transportation, and making it easier to remove the concrete channel from the mold.

[0035] Example 2

[0036] Based on Example 1, in order to compensate for the problem that the heavy concrete channel is prone to causing the baffle 102 to reset and close.

[0037] like Figure 2 and Figure 5 As shown, in this embodiment, the transmission assembly 3 includes: two fixed sleeves 301 respectively fixedly installed on one side surface of the two baffles 102, two threaded sleeves 302 respectively rotatably connected to the inside of the two fixed sleeves 301 through bearings, and a bidirectional screw 303 screwed into the inside of the two threaded sleeves 302.

[0038] In practice, by turning the two bidirectional screws 303, the threaded sleeve 302 and the bidirectional screws 303 are connected by screwing. Under the free rotation of the threaded sleeve 302, the threaded sleeve 302 rotates with the position, which facilitates the flipping of the baffle 102, provides power for the flipping of the baffle 102, and at the same time restricts the position of the baffle 102 to prevent the gravity of the concrete channel from squeezing the top plate 201 to move down and reset.

[0039] like Figure 2 As shown, in this embodiment, a slide rail 306 is symmetrically fixedly installed on one side surface of the side plate 101, and a sliding connecting seat 305 is slidably connected inside the slide rail 306. A bidirectional screw 303 rotates through the sliding connecting seat 305. A limit ring 304 is fixedly installed on the outer surface of the bidirectional screw 303 inside the sliding connecting seat 305, and hexagonal nuts 307 are fixedly installed at both ends of the bidirectional screw 303.

[0040] In practice, the limiting ring 304 rotates inside the sliding connecting seat 305 to prevent the bidirectional screw 303 from moving laterally. In conjunction with the sliding connecting seat 305, it can only slide up and down inside the slide rail 306, limiting the movement direction of the bidirectional screw 303 and improving the stability of the bidirectional screw 303.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
