[0027] The utility model provides a light steel structure hoisting facility, such as Figure 1 And Figure 2 As shown, including base 1, stand 2, electric hoist 3 and counterweight 4, stand 2 is fixedly installed at the edge of the top of base 1, to improve the connecting strength between stand 2 and base 1, can set up triangular inclined bracing on the both sides of stand 2, counterweight 4 is installed at the top of base 1, and is located at the end away from stand 2, electric hoist 3 is installed at the top of stand 2 through support, and the hook of electric hoist 3 extends out of base 1, facilitates hoisting, avoids the collision of steel structure and base 1 or stand 2 in the process of feeding and moving, the bottom of base 1 is equipped with drive wheel 5, still includes support column 6, transmission assembly, spring 7 and steel wire rope 8, the through hole is set up on base 1, support column 6 is slidably installed in the through hole, transmission assembly is rotatably connected with the top of base 1, and one end of transmission assembly is hinged with support column 6, and the other end is fixedly connected with one end of steel wire rope 8, the other end of steel wire rope 8 is slidably connected with the top of stand 2 and hook, spring 7 is sleeved on support column 6, and the both ends of spring 7 are respectively abutted with transmission assembly and base 1, when the bearing capacity of hook is greater than lifting capacity, the bottom end of support column 6 is in contact with the ground by overcoming the elastic force of spring 7, otherwise the bottom end of support column 6 is separated from the ground, in the above process, steel wire rope 8 is always in the state of being taut, and the tightness state of the connecting rope of electric hoist 3 is consistent or close to consistent, ensure that the bearing capacity on hook can be transmitted to steel wire rope 8 in the first time.

[0028] In this embodiment, the arrangement of the support column 6, transmission assembly, spring 7, and wire rope 8 serves two purposes: firstly, it prevents the steel structure from tipping over due to its weight exceeding the lifting capacity of the hoisting equipment; secondly, it shares some of the steel structure's weight, extending the service life of the electric hoist 3's connecting rope; and thirdly, it supports the steel structure in case the electric hoist 3's connecting rope breaks, preventing the steel structure from falling directly. Specifically, when the weight of the steel structure is less than or equal to the lifting capacity of the hoisting equipment, the bottom end of the support column 6 will not contact the ground under the constraint of the spring force of the spring 7, maintaining a certain distance between them. At this time, the hoisting equipment can move freely via the drive wheel 5. When the weight of the steel structure exceeds the lifting capacity during the loading process, including both fully and partially lifting the steel structure, the force exerted on the hook by the steel structure will cause the transmission component to rotate through the wire rope 8, thereby moving the bottom end of the support column 6 towards the ground until it contacts the ground. During this process, the spring 7 is continuously compressed. By observing whether the support column 6 contacts the ground or the distance between the two, the construction personnel can quickly determine that the weight of the steel structure is overloaded, and thus stop the loading operation to ensure safety. In addition, when the support column 6 contacts the ground, the hoisting equipment cannot move freely, which can prevent illegal operation and further ensure safety.

[0029] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the transmission assembly includes a support 9 and an adjusting rod 10. The middle part of the adjusting rod 10 is rotatably connected to the top of the base 1 through the support 9. One end of the adjusting rod 10 is hinged to the support column 6, and the other end is fixedly connected to the wire rope 8. A limit block 11 is also installed on the top of the base 1. The limit block 11 is fixedly installed below the adjusting rod 10 and located between the support column 6 and the support 9. When the adjusting rod 10 contacts the limit block 11, the compression of the spring 7 is not greater than the maximum compression. A support plate 12 is provided at the bottom end of the support column 6. The size of the support plate 12 is larger than the size of the through hole.

[0030] In this embodiment, the support 9 and the adjusting rod 10 enable the sliding of the support column 6 by lever principle; the limiting block 11 enables the position of the adjusting rod 10 to be hard-limited, thereby improving the service life of the spring 7; and the support plate 12 increases the contact area between the support column 6 and the ground, better protecting the ground and preventing the support column 6 from dislodging from the through hole.

[0031] In this utility model, preferably, such as Figure 1 As shown, a fixed pulley 13 is provided at the top of the column 2, and one end of the wire rope 8 is fixedly connected to the hook via the fixed pulley 13.

[0032] In this embodiment, by setting the fixed pulley 13, the sliding friction between the wire rope 8 and the top of the column 2 can be reduced, so that the load-bearing capacity of the hook can be better transferred to the adjusting rod 10.

[0033] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the steel wire rope 8 comprises multiple strands, which are symmetrically distributed on both sides of the hook.

[0034] In this embodiment, the arrangement of multiple symmetrically arranged steel wire ropes 8 can distribute more of the steel structure weight, improve safety performance, and enhance the stability of hoisting.

[0035] In this utility model, preferably, such as Figure 2 As shown, a tension sensor is provided between the wire rope 8 and the transmission assembly.

[0036] In this embodiment, by setting up a tension sensor, the weight of the steel structure can be measured in real time, which makes it convenient for operators to judge in advance whether the weight of the steel structure will exceed the limit. At the same time, the actual weight of the steel structure can also be roughly calculated by the reading of the tension sensor.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
