Description

Technical Field

[0001] The utility model relates to the technical field of slipform lifting equipment for concrete pouring construction, in particular to a slipform lifting device for building concrete construction. Background Art

[0002] Slipform engineering technology is a construction technology in my country's cast-in-place concrete structure construction that features high mechanization, fast construction speed, small site occupation, strong structural integrity, good seismic performance, guaranteed safe operation, and significant environmental and economic benefits. It is usually referred to as "slipform". At present, hydraulic jacks or hydraulic cylinders are mainly used as the sliding power. Under the synchronous action of the group jacks, the tool formwork or sliding frame is driven to slide along the newly formed concrete surface or the formwork surface. The concrete is poured into the sleeve groove from the upper mouth of the formwork in layers, and each layer is generally not more than 30cm thick. When the bottom layer of concrete in the formwork reaches a certain strength, the template sleeve groove slides along the poured concrete surface or the sliding frame slides along the outer surface of the formwork by relying on the action of the lifting machine, and then slides upward for about 30cm. This continuous cycle operation is carried out until the designed height is reached and the entire construction is completed. The existing hydraulic power slipform system uses a jack fixed on a supporting steel rod for lifting. The lifting control accuracy is low, and the overall stroke synchronization during lifting is poor, which poses a major safety hazard. In addition, there is a phenomenon of hydraulic oil leakage and pollution during the use of the hydraulic jack, which pollutes the cast concrete structure. The jack also needs to be replaced and repaired, which is costly. Utility Model Content

Specifically, the lifting bracket 1 is formed by welding and fixing steel sections. During construction, when the strength of the concrete structure 3 cast in the next layer reaches 0.1Mpa to 0.3Mpa, the operator controls the lifting bracket 1 to drive the sliding form 2 to lift, and each layer of the cast concrete structure 3 is 50mm lower than the upper edge of the sliding form 2.

[0022] A support rod 4 is fixedly provided vertically in the concrete structure 3 by pouring, and a lifting motor 5 is installed on the lifting bracket 1. In this embodiment, the lifting motor 5 uses a stepper motor with a reducer, and the number of rotations of the stepper motor can be accurately controlled during operation to achieve accurate control of the lifting height. A nut is provided at the output end of the lifting motor 5, and the lifting motor 5 can drive the nut to rotate after being powered. A hollow threaded screw 6 is connected to the output end of the lifting motor 5, and the hollow threaded screw 6 is connected to the nut through threaded power. Specifically, the lifting speed of the lifting bracket 1 driven by the lifting motor 5 is 300mm / min.

A support member 7 is detachably installed on the support rod 4, and an adapter 8 is rotatably installed at the end of the bottom end of the hollow threaded screw 6, and the bottom end of the adapter 8 is against the support member 4. When the lifting motor 5 is powered on and rotates forward, the hollow threaded screw 6 is driven downward by the nut, and the sliding form 2 is slid upward along the concrete structure 3 through the lifting bracket 1 under the support of the support member 7, so that the lifting operation is realized. When the sliding form 2 is lifted to the specified height, the lifting bracket 1 is fixed to the external structure, and then the lifting motor 5 is controlled to be powered on and rotated in the reverse direction, and the hollow threaded screw 6 is driven upward by the nut to move unloaded, and the support member 7 is removed and installed at the next support position, and the above operation is repeated to pour concrete until the construction is completed.
