Description

Technical Field

[0001] The present application relates to the field of concrete moulds, and in particular to a concrete pier mould. Background Art

[0002] During the construction of the pipeline corridor, in order to facilitate the installation of pipelines, a large number of concrete piers need to be cast in the pipeline corridor to support the pipelines. When casting the concrete piers, concrete pier molds are required.

[0003] At present, the concrete pier mold is mainly in the shape of a rectangular frame. When in use, the rectangular frame is placed at the concrete pier casting position, and then the concrete pier mold is kept stable, and then concrete is poured in the concrete pier mold. In order to make the size of the concrete pier reach the standard level, the concrete pier mold is customized according to the size of the concrete pier, and when pouring concrete, the concrete needs to be flush with the upper surface of the concrete pier mold, so as to ensure that the height of each concrete pier is consistent, so as to facilitate the bearing of the pipeline.

[0004] With regard to the above-mentioned related technologies, after the initial setting of the concrete, the concrete pier mold needs to be taken out, and the main way to take it out is to manually lift the concrete pier mold. However, since the concrete needs to be flush with the upper surface of the concrete pier mold, it is difficult to take out the concrete pier mold, and manually lifting the concrete pier is likely to cause damage to the initially set concrete pier. Utility Model Content

[0005] In order to facilitate the removal of the concrete pier mold, the present application provides a concrete pier mold.

[0006] The present application provides a concrete pier mold, which adopts the following technical solution:

[0007] A concrete pier mold comprises a frame, and lifting mechanisms for vertically moving the frame are installed on two opposite outer walls of the frame, the lifting mechanism comprises a sleeve and a lifting rod, the sleeve is installed on the outer wall of the frame, one end of the lifting rod is inserted in the sleeve, and the other end of the lifting rod extends out of the sleeve to abut against a supporting surface, and the lifting rod extends out of the sleeve to push the frame to move; an air injection mechanism for injecting air into the sleeve is installed on the frame, and the air injection mechanism injects air into the sleeve to make the lifting rod extend out of the sleeve.

[0008] By adopting the above technical solution, when the concrete is poured and initially solidified, the air injection mechanism is used to inject air into the sleeve to move the jacking rod. After the jacking rod abuts the supporting surface, it can push the frame to move vertically, so that the frame can be gradually separated from the concrete pier; the jacking mechanism is used to drive the frame to move vertically, which facilitates the frame to separate from the concrete pier.

[0009] Optionally, the gas injection mechanism includes an air cylinder and a piston, the air cylinder is fixed on the frame, the piston is arranged in the air cylinder, and the piston can move in the air cylinder, the air cylinder is connected to the sleeve, the piston moves to inflate or drain the sleeve, and a push rod is fixedly connected to the piston.

[0010] By adopting the above technical solution, when the sleeve is injected with gas, the push rod is used to push the piston to move, so that the lifting rod moves under the action of gas pressure; the gas injection mechanism has a simple structure and is easy to operate.

[0011] Optionally, the number of the gas injection mechanisms is two, and the two gas injection mechanisms are used to inject gas into the two sleeves respectively, and the frame is provided with a driving component for driving the two pistons to move closer to or away from each other.

[0012] By adopting the above technical solution, the driving assembly can drive the two pistons to move synchronously, thereby ensuring that the moving speeds of the jacking rods on both sides are consistent, thereby facilitating the frame to separate from the concrete pier.

[0013] Optionally, a sliding rod is fixedly connected to the push rod, and the sliding rod can slide on the frame. The driving assembly includes a bidirectional screw rod and a handle. The bidirectional screw rod is rotatably connected to the frame, and the handle is used to drive the bidirectional screw rod to rotate. The bidirectional screw rod rotates to drive the two sliding rods to move closer to or away from each other.

[0014] By adopting the above technical solution, when the slide rod is driven to move, the handle is rotated to drive the bidirectional screw rod to rotate, thereby driving the two slide rods to move closer to or away from each other. The bidirectional screw rod in the drive assembly has a certain limiting ability and can position the slide rod in a suitable position to a certain extent.

[0015] Optionally, the sleeve is rotatably connected to the frame, and the sleeve rotates to approach or move away from the frame. The frame is provided with a limiting component for limiting the sleeve from rotating toward the frame.

[0016] By adopting the above technical solution, when pouring concrete, the sleeve and the lifting rod can be set at an angle, so that the sleeve can be injected with air using the air injection mechanism to make the lifting rod contact the supporting surface, thereby preventing the frame from moving and ensuring the stability of the frame when pouring concrete.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] 1. The present application provides a jacking mechanism to push the frame to move vertically, so that the frame can quickly detach from the concrete pier after the initial setting of the concrete;

[0019] 2. The present application prevents the frame from moving by means of the rotating setting of the sleeve, thereby ensuring the stability of the frame during the pouring of concrete. BRIEF DESCRIPTION OF THE DRAWINGS
