Abstract
Description
Technical Field
[0001] The present application belongs to the field of construction technology, and specifically relates to a device for removing the bottom formwork of a tall aqueduct. Background Art
[0002] In recent years, my country is in the process of rapid construction of various water conservancy projects, and many water conservancy projects involve the construction of tall aqueducts. Tall aqueducts generally have large spans, high heights, high construction difficulty, and high risks. Especially when the bottom formwork of the aqueduct is removed after the concrete pouring of the tall aqueduct is completed, the support system of the bottom formwork must be removed first, which will cause the formwork to sway greatly when the bottom formwork of the aqueduct is removed, making removal difficult and posing a high safety risk. Utility Model Content
[0003] In view of the above problems existing in the prior art, the present invention provides a device for removing the bottom formwork of a tall aqueduct, which can effectively fix the formwork when the lower support frame of the bottom formwork is removed to prevent the formwork from shaking, and the formwork can be lowered symmetrically after the bottom support frame is removed.
[0004] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a device for dismantling the bottom formwork of a tall aqueduct, comprising: a connecting frame, an electric hoist, a wire rope and a hook. The connecting frame is horizontally erected on a connecting frame platform. The two ends of the connecting frame are respectively fixedly connected with electric hoists. The electric hoist hooks are connected to the wire ropes. Hooks are arranged at both ends of the wire rope. The hooks are respectively connected to the hanging points arranged on the template. Two hanging points are arranged at each end of the template and the hanging points are symmetrically arranged.
[0005] Furthermore, the electric hoist hook is connected to the midpoint of the steel wire rope, and the steel wire rope and the template form an isosceles triangle structure.
[0006] Furthermore, the electric hoist is fixed to the connecting frame by bolts.
[0007] Furthermore, the device also includes a controller, which is connected to the electric hoists and controls the two electric hoists to run simultaneously.
[0008] Furthermore, the device also includes an electronic level, which is installed on the template and connected to the controller.
[0009] Beneficial effects of this application:
[0010] The present application provides a device for removing the bottom formwork of a tall aqueduct. Electric hoists are arranged at both ends of a connecting frame to operate simultaneously and cooperate with each other. Before the support frame is installed, the hook of the electric hoist is connected to the template lifting point to effectively fix the template and prevent the template from shaking. After the removal of the bottom support frame is completed, the height and speed of the hoisted template are controlled to lower the template symmetrically. The device operates smoothly and efficiently, which not only ensures construction safety but also saves construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0016] As shown in the figure, the high aqueduct bottom formwork removal device includes: a connecting frame 1, an electric hoist 3, a wire rope 4 and a hook 5. According to the length of the bottom formwork 6 of the aqueduct to be removed, an electric hoist 3 connecting frame 1 is formed by processing with an I-beam. Bolt holes are opened at both ends of the connecting frame 1. The bolt holes are used to fix the electric hoist 3 and match the electric hoist 3 base. The electric hoist 3 base and the I-beam connecting frame 1 are firmly connected with bolts. After the electric hoist 3 is fixedly connected to the connecting frame 1, it is erected on the connecting frame platform 2. The connecting frame platform 2 is the concrete surface of the top of the aqueduct concrete. The concrete surface needs to be cleaned to ensure that the connecting frame 1 is placed at the same horizontal height.
[0017] After the connecting frame 1 is placed stably, a steel wire rope 4 is placed on the electric hoist hooks at both ends. The electric hoist hook is connected to the midpoint of the steel wire rope 4. The model of the steel wire rope 4 matches the weight of the hoisted template 6. The steel wire rope 4 and the template 6 form an isosceles triangle structure. Hooks 5 are set at both ends of the steel wire rope 4. The hooks 5 are respectively connected to the hanging points set on the removed template 6. Two hanging points are set at each end of the template 6, and the two hanging points are arranged symmetrically. After the electric hoist hook and the steel wire rope 4, the hook 5 and the hanging point are firmly suspended, the template 6 is stably supported to ensure that the template 6 is effectively fixed when the lower support frame of the bottom mold is removed, and no shaking occurs.
[0018] After the removal is completed, the two electric hoists 3 are started at the same time, and the operator simultaneously raises and lowers the hooks of the electric hoists 3 according to the lifting height to ensure that the template 6 descends smoothly and the removal of the template 6 is completed.
[0019] Furthermore, in order to facilitate the simultaneous operation of the electric hoist 3 and ensure that the template 6 is always hoisted and lowered in a horizontal state, the device is also provided with a controller and an electronic level, and the controller is connected to the electric hoist 3 and the electronic level. The two electric hoists 3 are controlled to operate simultaneously by the controller, and the horizontal state of the template 6 is measured by the electronic level. When the base of the level is tilted due to the tilt of the test piece, the voltage of the induction coil caused by the movement of the internal pendulum changes, thereby detecting the tilt of the template 6, and issuing a tilt alarm through the controller to notify the operator to check the device connection and adjust the device connection.
