Description

Technical Field

[0001] The utility model belongs to the technical field of sliding form support, in particular to a sliding form support structure with adjustable height. Background Art

[0002] Slipform construction is a construction technology, the main feature of which is to use a hydraulic lifting device to slide the formwork to cast a vertical concrete structure. The components of the slipform construction mainly include formwork, enclosure, lifting frame, operating platform, support rod and hydraulic jack. During construction, the hydraulic jack climbs on the support rod, driving the lifting frame and the formwork operating platform to rise together. After each layer of concrete is poured, the formwork is slid until the structure is poured. In the process of using the slipform, the support structure is generally used to support the slipform, and the slipform construction structure is also often used in the construction of small buildings.

[0003] The utility model patent with patent application publication number 202223394550.5 discloses an adjustable slipform construction support platform, which relates to the technical field of construction support platforms, including a base plate, wheels are arranged on the base plate, a fixing mechanism is arranged on the base plate, a slide cylinder is welded on the base plate, a slide rod is slidably connected in the slide cylinder, a table top is welded on the slide rod, a column is welded on the table top, an adjustment mechanism is arranged on the column, and a template is detachably installed on the column. By installing wheels on the base plate, fixing an electric motor on the base plate, welding a screw on the rotating shaft of the motor, a support plate is arranged on the outside of the screw, and an insert cylinder is welded on the support plate, the wheels make the device as a whole easy to move and adjust, and the electric motor drives the screw to rotate and the support plate to make a threaded movement, so that the insert cylinder can be moved into the ground, so that the device as a whole can be stably placed on the ground while facilitating the movement and adjustment of the position.

[0004] However, the above device still has shortcomings in actual use. The most obvious one is that the lifting and lowering of the sliding form support platform is achieved by the coordinated use of the screw and the barrel. When the load of the sliding form support platform is too heavy, it is easy to reverse the rotation of the barrel thread on the screw, thereby reducing the height of the sliding form support platform. The self-locking ability is poor, which affects the lifting effect of the sliding form support platform. For this reason, we propose a sliding form support structure with adjustable height. Utility Model Content

[0005] The purpose of the utility model is to provide a sliding formwork support structure with adjustable height to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0010] As a preferred technical solution of the present application, an annular block is fixedly connected to the bottom of the worm wheel, an annular groove for rotation of the annular block is provided on the top of the support column, and a connecting groove for facilitating the lifting and lowering of the first screw is provided on the top of the support column.

[0011] The top of the base is fixedly connected to two sides away from each other with telescopic rods, the telescopic rods are fixedly connected to the bottom of the fixing frame, and a supporting assembly for supporting the worm is arranged on the telescopic rods.

[0012] The support assembly comprises a mounting plate, the mounting plate is fixedly connected between the outer side walls of the two groups of telescopic rods, and a fixing block for rotating the connecting worm is arranged on the top of the mounting plate.

[0013] The transmission mechanism includes an L-shaped support frame, which is fixedly connected to the side wall of the mounting plate, and the side wall of the L-shaped support frame away from the mounting plate is fixedly connected to a motor, the power output end of the motor passes through the side wall of the L-shaped support frame and is fixedly connected to a rotating shaft, the outer side walls of the rotating shaft are fixedly connected to second sprockets on both sides away from each other, the outer side wall of the connecting rod is fixedly connected to the first sprocket, and a chain for transmission is arranged between the second sprocket and the first sprocket.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] In the scheme of this application:

[0017] 1. By setting a worm, a worm wheel and a first screw, the worm drives the worm wheel to rotate. At this time, the worm wheel rotates in the annular groove through the annular block. Since a threaded groove matching the first screw is opened in the worm wheel, and the first screw is connected to the fixed frame, the worm wheel can drive the first screw to rise and fall when it rotates. The fixed frame and the template are driven to rise and fall through the first screw and the telescopic rod. Since the lifting and lowering of the first screw requires the rotation of the worm wheel, the worm wheel cannot drive the worm to rotate. Therefore, the first screw has a good self-locking ability when supporting, which ensures the lifting and lowering effect of the sliding formwork support platform.

[0018] 2. By opening a trapezoidal groove on the fixed frame, the template is installed between the fixed frames through the trapezoidal slider, and by rotating the second screw, the second screw drives the limit block to move horizontally, and the trapezoidal slider is limited in the trapezoidal groove by the limit block, thereby facilitating the disassembly and assembly of the template.
