Description

Technical Field

[0001] The utility model relates to the technical field of lifting belts, in particular to a lifting belt for a bridge bottom support mesh sheet. Background Technique

[0002] A sling is a connecting belt used for mechanical hoisting and lifting, and it is often used in large-scale construction projects. Among them, during the construction process of bridge construction, the beam and the bridge deck are generally prefabricated into finished products in an enterprise and then transported to the construction site for hoisting construction. At present, when hoisting operations are carried out on structures such as beams and bridge decks, a slender sling is used for hoisting. These slings are generally hung at both ends of the precast beam and the precast bridge deck. For some precast beams or bridge decks with larger volumes, several slings will also be added in the middle according to needs, and then a hoisting device is used to lift each sling together. However, in this hoisting method, the stress points are small, resulting in a lack of hoisting stability. Content of the Utility Model

Front sling groups and rear sling groups are respectively arranged on the front and rear sides of the lower end surface of the pallet, and a detachable protective surface is arranged on the upper end surface of the pallet;

[0005] The protective surface includes an upper wear-resistant layer and a lower wear-resistant layer sewn together with each other, and a deformable metal grid is arranged between the upper wear-resistant layer and the lower wear-resistant layer.

[0006] Further, the protective surface is connected to the upper end surface of the pallet through a detachable member.

[0007] Further, the detachable member is a mother-and-son buckle or a magic tape, and the mother-and-son buckle or the magic tape is respectively arranged on the lower end surface of the lower wear-resistant layer and the upper end surface of the pallet.

[0008] Further, anti-slip lines are arranged on the upper end surface of the upper wear-resistant layer.

[0009] Further, the front sling group includes a first sling and a second sling fixedly arranged on the pallet in an X shape, and the rear sling group includes a third sling and a fourth sling fixedly arranged on the pallet in an X shape. One end of each sling extends obliquely outwards towards the outer sides of the four end corners of the pallet, and the other end of each sling extends obliquely outwards towards the outer side of the middle of the pallet.

[0010] Further, the part of the first sling facing the middle of the tray and the part of the third sling facing the middle of the tray cross each other and are fixedly connected; the part of the second sling facing the middle of the tray and the part of the fourth sling facing the middle of the tray also cross each other and are fixedly connected.

[0018] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0020] Such as Figures 1-3As shown in the figure, a lifting belt for the bottom net of a bridge according to this embodiment includes a rectangular soft pallet 1. Front sling groups and rear sling groups are respectively arranged on the front and rear sides of the lower end surface of the pallet 1, and a detachable protective surface 2 is arranged on the upper end surface of the pallet 1;

[0021] The protective surface 2 includes an upper wear-resistant layer 2a and a lower wear-resistant layer 2b sewn together. A deformable metal grid 2c is arranged between the upper wear-resistant layer 2a and the lower wear-resistant layer 2b to combine the upper and lower wear-resistant layers with the metal grid 2c, improving the wear resistance of the protective surface 2 and thus increasing its service life.

[0022] The protective surface 2 is connected to the upper end surface of the pallet 1 through a detachable part.

[0023] The detachable part is a mother-and-son buckle or a magic tape, and the mother-and-son buckle or the magic tape is respectively arranged on the lower end surface of the lower wear-resistant layer 2b and the upper end surface of the pallet 1.

[0024] The structure of the mother-and-son buckle or the magic tape is not shown in the figure. The mother-and-son buckle or the magic tape can be installed along the edges of the lower wear-resistant layer 2b and the pallet 1, or evenly distributed on the lower wear-resistant layer 2b and the pallet 1.

[0025] Anti-slip lines are arranged on the upper end surface of the upper wear-resistant layer 2a. The anti-slip lines improve the anti-slip performance of the upper wear-resistant layer 2a and the stability of the lifting.

[0026] The front sling group includes a first sling 3 and a second sling 4 fixedly arranged on the pallet 1 in an X shape. The rear sling group includes a third sling 5 and a fourth sling 6 fixedly arranged on the pallet 1 in an X shape. One end of each sling extends obliquely outward to the outside of the four end corners of the pallet 1, and the other end of each sling extends obliquely outward to the outside of the middle of the pallet 1.

[0027] The part of the first sling 3 facing the middle of the pallet 1 and the part of the third sling 5 facing the middle of the pallet 1 cross and are fixedly connected to each other; the part of the second sling 4 facing the middle of the pallet and the part of the fourth sling 6 facing the middle of the pallet 1 also cross and are fixedly connected to each other.

[0028] Lifting rings 7 are arranged at both ends of the first sling 3, the second sling 4, the third sling 5 and the fourth sling 6.

[0029] Preferably, the materials of the upper wear-resistant layer 2a and the lower wear-resistant layer 2b are both polypropylene fibers, and the grid 2c is a steel wire grid.

[0030] Preferably, the pallet 1 and the sling group are both made of nylon fiber material.

[0031] When the utility model is in use, the side of the tray 1 with the protective surface 2 is placed at the lower end of the precast beam or the precast bridge deck. The protective surface 2 is arranged in a fitting manner with the lower end surface of the above-mentioned precast member. Then, the lifting rings 7 at the ends of each sling are connected by using a lifting device. When the lifting device hoists the precast member upward, the entire tray 1 will be supported under the precast member, and the crossed slings will surround both sides of the precast member. In this way, the precast beam or the precast bridge deck can be hoisted, which can improve the stability of the hoisting and also ensure the stability of the precast member, avoiding the phenomenon of strangulation damage caused by the small stress surface of the sling.

[0032] The embodiments of the present utility model are given for the purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
