Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hoisting equipment, and in particular relates to a special hoist for a prefabricated stand plate of a stadium. Background Art
[0002] In the construction process of modern stadiums, in order to meet the requirements of urgency of construction period and aesthetics, more and more stadiums choose to use precast concrete stand panels as the structure of the stands. This design has the characteristics of large span, heavy weight, special style, etc., which brings a series of challenges to the hoisting process.
[0003] The traditional lifting method for prefabricated stand panels requires that an ordinary sling be passed through the bottom of each end of the stand panel for lifting. However, after the lifting is completed in this way, the slings often cannot be withdrawn smoothly, which brings many inconveniences to the subsequent construction. In addition, the direct contact and friction between the slings and the prefabricated stand panels make it difficult to protect the finished prefabricated stand panels, and collisions are prone to occur during the lifting process, resulting in damage to the stand panels, which increases the workload of subsequent maintenance. In order to solve these problems, the utility model provides a special lifting device for prefabricated stand panels for stadiums to prevent the slings from hard contact with the stand panels, resulting in damage to the stand panels, resulting in a large workload of subsequent maintenance.
[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special hanger for prefabricated stands in a stadium, comprising a hanger body and anti-slip pad corners, the hanger body comprising a first baffle plate, a second baffle plate being slidably connected to the bottom of the first baffle plate, a lifting ear being fixed to the top end face of the first baffle plate, a through hole being provided at the other end of the first baffle plate and the second baffle plate, the two through holes being collinearly arranged, screws being installed inside the two through holes, and fixing nuts being threadedly connected to the rod shafts at both ends of the screws.
[0006] As a preferred technical solution of the present utility model, anti-slip pads are provided on the inner sides of the two fixing nuts located on the first baffle plate and the second baffle plate.
[0007] As a preferred technical solution of the utility model, the number of the sling body and the anti-slip pad corners is not less than two.
[0008] As a preferred technical solution of the present utility model, the corner cross-section of the anti-slip pad is L-shaped.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] The utility model places a grandstand board between two baffles, adjusts the distance between the two baffles, uses a fixing nut to tighten and clamp the grandstand board, then connects a lifting ear on the first baffle board and a lifting ring on the grandstand board through a sling, places an anti-skid pad corner at a position where the sling and the grandstand board contact, and finally lifts the grandstand board. The overall operation is convenient, and hard contact between the sling and the grandstand board, which would cause damage to the grandstand board and result in a large amount of maintenance work in the later stage, is prevented. At the same time, the structure is simple, and the production and operation are convenient. The distance between the two baffles can be adjusted according to the thickness of different grandstand boards, thereby improving versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] Example
[0017] See also Figure 1-2The utility model provides the following technical solutions: A special hoist for prefabricated stands in a stadium, comprising a hoist body 8 and an anti-skid pad corner 1. The hoist body 8 is composed of a first baffle 2 and a second baffle 3, which are connected to each other by a sliding connection. The bottom of the first baffle 2 is connected to the second baffle 3, and a lifting ear 4 is fixed on the top of one end, and a through hole is opened together with the second baffle 3 at the other end, and the two through holes are arranged in a collinear manner. The screw 6 passes through the two through holes, and its two ends are respectively connected to the fixing nut 7. When it is necessary to adjust the distance between the first baffle 2 and the second baffle 3, the distance is adjusted by rotating the hoist body 8 and using the opposite characteristics of the threads at both ends of the screw 6. After the adjustment is completed, it is fixed by using the fixing nut 7. During the hoisting process, the sling is connected to the lifting ear 4 and the lifting ring on the stand, and the anti-skid pad corner 1 is placed at the position where the sling contacts the stand, and finally hoisting is performed. This hoist is simple in design and easy to use, and the distance can be adjusted according to the stand of different thicknesses, which greatly improves the convenience of production and operation.
[0018] In order to prevent the fixing nuts 7 from loosening, in this embodiment, as a preferred technical solution of the utility model, anti-slip pads 5 are provided on the inner sides of the two fixing nuts 7 located on the first baffle plate 2 and the second baffle plate 3 .
[0019] In order to increase the safety and stability of the grandstand panels during hoisting, in this embodiment, as a preferred technical solution of the utility model, the number of the hoisting device body 8 and the anti-slip pad corner 1 is not less than two.
[0020] In order to facilitate the adaptation to the corners of the stand board, in this embodiment, as a preferred technical solution of the utility model, the cross-section of the anti-slip pad corner 1 is an L-shaped structure.
[0021] To summarize, with the aid of the above-mentioned technical scheme of the utility model, since the thickness of the stands of the grandstand is different, firstly, the distance between the first baffle plate 2 and the second baffle plate 3 is adjusted by rotating the two fixing nuts 7. After adjusting the distance between the two baffle plates, it is installed at one end of the grandstand plate so that one end of the grandstand plate is placed at the opening of the first baffle plate 2 and the second baffle plate 3. The two fixing nuts 7 are tightened to clamp and fix one end of the grandstand plate with the aid of the two baffle plates. Then, the sling is connected to the lifting ear 4 on the first baffle plate 2 and the lifting ring on the grandstand plate, and the anti-slip pad corner 1 is placed at the position where the sling and the grandstand plate contact, and finally the grandstand plate is lifted. Since the grandstand plate has a certain length, at least two sling bodies 8 and anti-slip pad corners 1 are required, which are symmetrically installed at both ends of the grandstand plate to improve the safety and stability of lifting the grandstand plate.
[0022] Finally, it should be noted that in the present utility model, unless otherwise clearly stipulated and limited, terms such as "installation", "setting", "connection", "fixation", and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.
