[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0023] like Figure 1 , 2 As shown: A hoisting fixing device includes four fixing plates 101 arranged in a rectangle. The four fixing plates 101 are arranged so that the four sides of the object to be hoisted can be fixed, especially for objects with sharp edges. Each fixing plate 101 is designed with an L-shaped structure, which can further improve the fixing effect. The two ends of each fixing plate 101 can limit the two sides of the object to be hoisted. The fixing plates 101 can be integrally formed by casting with a mold during manufacturing, so that the connection structure is more stable and the manufacturing speed can be improved. The inner sidewalls of the four fixing plates 101 are correspondingly arranged, so that the four inner sidewalls of the four fixing plates 101 form a rectangular space, which can further improve the support effect, so that the object to be hoisted can be fixed between the four fixing plates 101 before hoisting.
[0024] Each fixing plate 101 has a first mounting hole 102 symmetrically formed on one vertical surface, and a second mounting hole 103 symmetrically formed on the vertical surface perpendicular to the side with the first mounting hole 102. The first mounting holes 102 and the second mounting holes 103 are provided so that the threaded rod 105 can pass through them, thereby supporting the four fixing plates 101. The distance between each pair of corresponding fixing plates 101 can be adjusted, so that items of various sizes can be fixed. The two first mounting holes 102 and the two second mounting holes 103 can be integrally formed by casting the fixing plates 101 with a mold during manufacturing, so that the connection structure is more stable and easy to mass-produce. The two first mounting holes 102 and the two second mounting holes 103 on each pair of adjacent fixing plates 101 correspond to each other so that the threaded rod 105 can be inserted into them. Moreover, the two first mounting holes 102 and the two second mounting holes 103 on each fixing plate 101 are not on the same horizontal plane, thereby avoiding the threaded rod 105 from colliding with each other.
[0025] A threaded rod 105 is inserted into the corresponding first mounting hole 102 and second mounting hole 103 on each pair of adjacent fixing plates 101. The threaded rods 105 can limit the four fixing plates 101 through multiple threaded rods 105 and facilitate disassembly and assembly. Each threaded rod 105 has a fastening nut 106 connected to both ends and the outside of each fixing plate 101 through threaded engagement. The fastening nuts 106 can fix each pair of adjacent fixing plates 101 and adjust the spacing, so that the four fixing plates 101 can provide stable support for the items to be hoisted.
[0026] In use, first place the four fixing plates 101 on the four sides of the item to be hoisted, then insert multiple threaded rods 105 into multiple first mounting holes 102 and multiple second mounting holes 103 in sequence, and then connect multiple fastening nuts 106 to both ends of each threaded rod 105 through threaded engagement. Thus, the item to be hoisted can be fixed without much work experience, without much cost, and can be reused multiple times. It is also relatively convenient in the process of assembly and disassembly.
[0027] like Figure 1 , 2 As shown: Each fixing plate 101 is provided with a support plate 104 at its lower part. The support plate 104 can further improve the support effect. When fixing lighter items, simply lift the four corners and place the fixing plate 101 on the four sides of the item. When fixing heavier items, use a forklift to insert it and place it on the four sides of the item. The support plate 104 is fixedly connected to the lower part of the fixing plate 101, thereby making the connection structure more stable. The support plate 104 can support the lower part of the item to be lifted, so that the item to be lifted can be lifted without excessive clamping.
[0028] like Figure 2 , 3 As shown: Each fixing plate 101 has a buffer pad 107 on its inner side wall. The buffer pad 107 is provided to prevent damage to the surface of the item when the four fixing plates 101 are used to fix the item, thereby preventing damage to the item that needs to be hoisted. The buffer pad 107 is fixedly connected to the inner side wall of the fixing plate 101, thereby making its connection structure more stable.
[0029] like Figure 2 As shown: The buffer pad 107 is made of rubber. The use of rubber increases its service life, and its soft material prevents damage to the hoisted items.
[0030] like Figure 1As shown: Each fastening nut 106 is provided with a locking washer between itself and each fixing plate 101 and on the outer wall of the threaded rod 105. The locking washers are provided to prevent the fastening nut 106 from loosening due to shaking during hoisting, thereby further improving safety.
[0031] like Figure 2 , 3 As shown: Each fixed plate 101 is provided with a mounting plate 108 on its upper part. The mounting plate 108 is provided to support the hanging ring 109 installed on it. The mounting plate 108 is fixedly connected to the upper part of the fixed plate 101, thereby making the connection structure more stable. Each mounting plate 108 is provided with a hanging ring 109 on its upper part, so that ropes can be tied to it, thereby making the crane more stable in lifting it. The hanging ring 109 is fixedly connected to the upper part of the mounting plate 108, thereby making the connection structure more stable.
[0032] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
