Technical Field
[0001] This utility model belongs to the technical field of bridge construction auxiliary equipment, specifically relating to an automatic hoisting device for wet joint templates. Background Technology
[0002] Formwork installation is a crucial step in the construction of wet joints in bridges. Its quality directly determines the appearance, size, and density of the concrete at the joint, which in turn affects the overall alignment, load-bearing capacity, and durability of the bridge.
[0003] In traditional bridge wet joint construction, formwork installation typically relies on manual handling and hoisting for positioning, which is inefficient, labor-intensive, and poses safety hazards. Existing hoisting equipment is mostly large cranes, which lack flexibility and are costly. Furthermore, the hooks are difficult to remove from the bottom of the beam after hoisting. Therefore, there is an urgent need for a lightweight and specialized formwork hoisting solution. Utility Model Content
[0004] To address the aforementioned issues, this utility model discloses an automatic hoisting device for wet joint templates. It features a simple structure and flexible movement, achieving rapid hoisting and positioning of templates through a combination of an angle steel frame and an electric lifting system.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An automatic hoisting device for wet joint templates includes a left support frame, a right support frame, a connecting rod, hoists, and an electromagnet. The left and right support frames are frame platforms welded from structural steel. Rollers are installed below the left and right support frames. The connecting rod connects the left and right support frames and is a sleeve. Two hoists are respectively installed above the left and right support frames. The electromagnet is located at the end of the hoisting rope below the hoist.
[0006] As an improvement of this utility model, the left support frame and the right support frame are rectangular platforms or right-angled trapezoidal platforms welded from angle steel and square tubes.
[0007] As an improvement of this utility model, the hoist is connected to the square tube above the left support frame and the right support frame via connecting plates.
[0008] As an improvement of this utility model, a brake pad is provided at the roller.
[0009] As an improvement of this utility model, the connecting rod is composed of two square tubes of different sizes, and the two square tubes are provided with connecting holes, in which movable pins are inserted.
[0010] As an improvement of this utility model, the two ends of the connecting rod are inserted into the positioning frames on the sides of the left and right support frames.
[0011] As an improvement of this utility model, electric controllers are provided on the sides of the left and right support frames.
[0012] The beneficial effects of this utility model are as follows: (1) This device can replace manual labor and cranes for the installation of templates, increasing efficiency by more than 50%; (2) Adding a connecting rod in the middle can adjust the distance between the two ends, making it easier to hoist; (3) The end of the hoist is changed to an electromagnet, which can be directly attracted to the iron tie rod of the formwork, so that the hooks do not need to be installed and removed manually, thus solving the problem that the hooks are difficult to remove at the bottom of the beam; (4) Reduce labor and hoisting machinery, save construction costs and ensure construction safety.

[0017] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0018] As shown in the figure, the automatic hoisting device for wet joint templates of this utility model includes a left support frame 1, a right support frame 2, a connecting rod 3, a hoisting hoist 4, and an electromagnet 5. The left support frame 1 and the right support frame 2 are frame platforms welded from structural steel. Rollers 6 are installed below the left support frame 1 and the right support frame 2. The connecting rod 3 connects the left support frame 1 and the right support frame 2 and is a sleeve. The two hoists 4 are respectively installed above the left support frame 1 and the right support frame 2. The electromagnet 5 is located at the end of the hoisting rope below the hoisting hoist 4.
[0019] The left support frame 1 and right support frame 2 of this utility model are rectangular or right-angled trapezoidal platforms welded from angle steel and square tubing. Figure 1 and 3As shown, the device is welded using #5 angle steel. The connecting rod 3 in the middle is composed of two square tubes of different sizes. The two square tubes are provided with connecting holes 9, and movable pins 10 are inserted into the connecting holes 9 to adjust the distance between the two ends, which facilitates better hoisting. During hoisting, the device is first placed across the wet joint of the two beams. Then, two electromagnets 5 are attracted to the iron tie rod of the template. The hoisting hoist 4 is started to lift the template to the wet joint. After it is in place, the pouring is carried out. In this utility model, the end of the hoisting hoist is changed to an electromagnet 5, which is directly attracted to the iron tie rod of the template. This eliminates the need for manual installation and removal of hooks, solving the problem that the hooks are difficult to remove from the bottom of the beam.
[0020] The hoist 4 described in this utility model is connected to the square tubes above the left support frame 1 and the right support frame 2 via connecting pieces 7, such as... Figure 2 As shown, the hoist 4 is a PA400 mini electric hoist with a rated lifting capacity of 200 / 400kg and a lifting height of 6m / 12m. The output shaft is connected to a drum for winding steel wire rope with a diameter of 6mm. The end of the steel wire rope is connected to an electromagnet 5 for attracting the template. The hoist 4 can achieve forward and reverse rotation through the electric controller 12 to control the lifting and stopping of the template.
[0021] The left support frame 1 and the right support frame 2 of this utility model have rollers 6 at the bottom of their legs, which can achieve flexible positioning. The rollers 6 are equipped with brake pads 8, which can stop at the designated position during construction.
[0022] The two ends of the connecting rod 3 of this utility model are inserted into the positioning frame 11 on the side of the left support frame 1 and the right support frame 2, and can be disassembled when not in use, thus reducing the floor space occupied.
[0023] This utility model has an electric controller 12 installed on the inner side of the left support frame 1 and the right support frame 2, so that one person can control the two switches at the same time and achieve basic synchronous control.
[0024] This utility model has a simple structure and is flexible in movement, which can greatly improve construction efficiency, reduce labor and hoisting machinery, save construction costs, and ensure construction safety.
[0025] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
