Detailed ways

Embodiments of the utility model will be described in further detail below in conjunction with the accompanying drawings.

Referring to Fig. 1-Fig. 2, the embodiment of the utility model provides a prefabricated ditch cover lifting device, including a lifting bracket 1 and a lifting assembly 2, wherein the lifting bracket 1 is similar to the shape of a table, with four ends Both parts are provided with legs, and the lifting bracket 1 is used for transshipment within a certain distance after the cover is lifted. The length and width of the lifting bracket 1 are 2-3m. In order to facilitate the movement of the lifting bracket 1, universal wheels 10 are provided on the bottom of the supporting legs of the lifting bracket 1 to facilitate the flexible rotation and movement of the lifting bracket 1. In order to facilitate positioning, stoppers are also provided on the universal wheels 10 11. It can effectively place the lifting bracket 1 to move back and forth when it is fixed, which affects lifting and transfer.

Referring to Figures 1-2, the lifting assembly 2 includes a lifting rod 20, a driving part 23 and a spreader assembly. The assembly includes a first hanger 21 and a second hanger 22. Either one of the first hanger 21 and the second hanger 22 is detachably hung on the drive member 23. The first hanger 21 is used for the solidification of the cover plate. Lifting, the second spreader 22 is used for lifting when the cover plate is not solidified.

Specifically, due to the need for flexible movement in the lifting process to achieve rapid lifting of the cover, and the lifting bracket 1 is relatively large in size, it is inconvenient to adjust the lifting bracket 1 to accurately locate it, which will bring great inconvenience to the operator. . Therefore, a chute is provided at the top of both sides of the lifting bracket 1, and correspondingly, the two ends of the lifting rod 20 are provided with pulleys 24 matching the chute, and the lifting rod 20 can reciprocate along the chute to facilitate quick adjustment. Location. When the position is adjusted, after starting to lift, in order to prevent the sliding of the lifting rod 20, the two ends of the lifting rod 20 are also provided with a limiter 25, and the limiter 25 is used to limit the relative movement of the lifting rod 20 and the lifting bracket 1.

Specifically, the driving member 23 here is preferably an electric hoist, and the electric hoist is slidably arranged on the lifting rod 20 and can reciprocate along the length direction of the lifting rod 20 . Both the lifting rod 20 and the driving part 23 can realize the function of sliding, which can effectively help the arbitrary positioning of the first sling 21 or the second sling 22 within a certain range during the lifting process, which greatly facilitates the operation of the operator. Reasonable structure.

Further, since the driving part 23 can move along the length direction of the lifting rod 20, in order to prevent the driving part 23 from slipping out of one end of the lifting rod 20 during the moving process to cause accidents or inconvenience, therefore, at the two ends of the lifting rod 20 Both are provided with a limiting plate 3, the limiting plate 3 is a rectangular plate with a certain shielding area, and the limiting plate 3 is vertically arranged with the end face of the lifting rod 20.

Referring to Fig. 3, the first hanger 21 includes a first hanging part 212 and two suspenders 210 which are rotatably arranged on the first hanging part 212. The first hanging part 212 is provided with a hook for hanging Hold under the electric hoist, the electric hoist can drive the first spreader 21 to move up and down in the vertical direction. The two suspenders 210 are arranged at intervals and rotate parallel to each other on the first hanging part 212. The end of the suspender 210 away from the first suspender 21 is provided with a first hook 211. The first hook 211 is used for hanging and fixing The solidified cover that needs to be lifted.

Referring to Fig. 4, the second hanger 22 includes a second hanging part 222 and a square hanging frame 220, the square hanging frame 220 is horizontally hung on the second hanging part 222, and the four ends of the square hanging frame 220 are respectively The second hanging part 222 is fixed by the hanging rope, and the second hanging part 222 is provided with a hook. The four ends of the square hanging frame 220 are all provided with a second hook 221. It is used to hang and fix the formwork with the unsolidified cover plate that needs to be lifted, so as to ensure that the cover plate will not be damaged as much as possible when the unsolidified cover plate is lifted.

Referring to shown in Fig. 1, two limit rods 4 are also provided on the lifting bracket 1, and the two limit rods 4 are arranged on the top of the lifting rod 20 at intervals parallel to each other, stick to the top of the lifting rod 20, and are connected to the top of the lifting rod 20. Vertical, the two limit rods 4 are used to limit the lifting rod 20 when lifting the cover plate or the formwork with the cover plate, because the lifting cover plate is too heavy, the lifting rod 20 will flip along its axial direction, causing lifting accidents and damage cover plate.

Further, in order to facilitate the operator to move the lifting bracket 1 , a pull rod 5 is also provided on the lifting rod 20 . Wherein, the distance between the two limit rods 4 is larger than the width of the pull rod 5, so as to ensure that the pull rod 5 can be lifted and dropped freely.

The utility model is not only limited to the above-mentioned best implementation mode, anyone can draw other various forms of products under the enlightenment of the utility model, but no matter make any changes in its shape or structure, anyone who has the same features as the utility model The same or similar technical solutions are all within the scope of protection.
