Description

Technical Field

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

[0002] Slipforms not only include ordinary or special tool formworks, but also include comprehensive technologies such as power sliding equipment and supporting construction processes. The main sliding power is hydraulic jacks. Under the synchronous action of group jacks, the tool formwork or sliding frame more than 1 meter high is driven to slide along the newly formed concrete surface or formwork surface. The concrete is poured into the sleeve groove in layers from the upper mouth of the formwork. Each layer is generally not more than 30 cm thick. When the bottom layer of concrete in the formwork reaches a certain strength, the formwork sleeve groove relies on the action of the lifting machine to slide along the poured concrete surface or the sliding frame slides along the outer surface of the formwork and slides upward for about 30 cm. This operation is repeated in a continuous cycle until the designed height is reached and the entire construction is completed.

[0003] As a modern concrete engineering structure with high efficiency and fast mechanical construction method, slipform construction technology is widely used in all walks of life in civil engineering. The existing slipform usually adopts the method of jacking and guide wheels, and has the following problems: the existing jacking method has a relatively complex structure and occupies a large space. The hydraulic press cannot jack normally during the extension and retraction process, the construction efficiency is low, and the sliding of the slipform cannot be guided, which is prone to certain deviations.

[0015] The beneficial effects of the utility model are:

[0016] 1. The utility model provides a movable sleeve, and the air pump will transport gas to the inner cavity of the sliding jack through the power interface, thereby increasing the air pressure at the top of the inner wall of the sliding jack, driving the movable sleeve to move downward. When the movable sleeve moves downward, the air pressure in the middle of the inner cavity of the sliding jack will increase. At this time, the air pressure will enter the interior of the slot through the through hole, thereby pushing the first locking block to lock the screw rod. At the same time, the pressure in the inner cavity of the sliding jack will push the second locking block through the tapered groove to keep it away from the screw rod, so that the fixed sleeve drives the structure outside the device to move upward, thereby realizing the overall lifting of the device.

[0017] 2. The utility model sets a first spring and a fixed sleeve block. After the device is lifted upward, the external air pump stops supplying air. At this time, the first spring inside the sliding jack will push the movable sleeve upward through its own elastic force. During this process, the air pressure in the middle of the inner wall of the sliding jack will decrease. At this time, the second spring will drive the first locking block through its own pulling force to retract it into the inner cavity of the card slot, so that the movable sleeve can slide on the side of the screw rod, and at this time, the third spring will push the second locking block through its own elastic force, so that the second locking block locks the screw rod, thereby achieving the lifting of the screw rod, which is beneficial to improving the working efficiency of the device.

[0018] 3. The inner and outer sliding forms of the utility model are easy to splice, and the sliding form fixing frame is convenient for limiting the inner and outer sliding forms, thereby improving the stability of the device; by arranging inclined rods and platform support plates, it is convenient to lift the inner and outer operating platforms and reinforce the stilt frame, which can further improve the stability of the device.

[0019] 4. The jacking method of the utility model is easy to operate, occupies little space, has low construction efficiency, and is convenient for guiding the sliding of the sliding form to avoid deviation. BRIEF DESCRIPTION OF THE DRAWINGS

The power interface 1102 is externally connected to an air pump, and a movable sleeve 1103 is slidably connected to the top of the sliding form jack 11, and a fixed sleeve 1105 is fixedly connected to the bottom. A first spring 1104 is provided on the inner wall, and the top of the first spring 1104 is fixedly connected to the bottom of the movable sleeve 1103, and the bottom is fixedly connected to the top of the fixed sleeve 1105. The screw rod 12 passes through the movable sleeve 1103 and the fixed sleeve 1105, and the screw rod 12 is slidably connected to the inner wall of the movable sleeve 1103, and movable clamping components are respectively provided inside the movable sleeve 1103 and the fixed sleeve 1105, and the movable clamping components are clamped with the screw rod 12;

[0054] The movable clamping assembly includes a clamping slot 11031, a through hole 11032, a first locking block 11033, a second spring 11034, a mounting slot 11051, a conical slot 11052, a second locking block 11053, and a third spring 11054; the clamping slots 11031 are evenly distributed in the circumference and radial direction at the bottom of the inner wall of the movable sleeve 1103, the through hole 11032 is opened at the bottom of the clamping slot 11031, the first locking block 11033 is slidably connected in the clamping slot 11031, the second spring 11034 is installed in the clamping slot 11031 and connected to the first locking block 11033, and the first locking block 11033 is connected to the second spring 11034 through the first locking block 11033.

[0056] When the upward movement is completed, the external air pump stops supplying air. At this time, the first spring 1104 inside the sliding jack 11 will push the movable sleeve 1103 upward and pull the second crossbeam 103 upward by its own elastic force. During this process, the air pressure in the middle of the inner wall of the sliding jack 11 will decrease. At this time, the second spring 11034 will drive the first locking block 11033 by its own pulling force, so that it can be recovered to the inner cavity of the slot 11031, so that the movable sleeve 1103 can slide on the side of the screw rod 12, and at this time, the third spring 11054 will push the second locking block 11053 by its own elastic force, so that the second locking block 11053 can lock the screw rod 12, thereby realizing the lifting of the screw rod 12, which is beneficial to improving the working efficiency of the device.

[0057] The inner sliding form 7 and the outer sliding form 5 of the utility model are easy to splice, and the sliding form fixing frame 2 is convenient for limiting the inner sliding form 7 and the outer sliding form 5, thereby improving the stability of the device; by arranging the inclined rod 3 and the platform support plate 302, it is convenient to lift the inner and outer operating platforms and reinforce the tripod 4, which can further improve the stability of the device.
