Detailed Description
In order to further describe the technical means and effects adopted by the utility model for achieving the preset aim, the following detailed description is given below of the specific implementation, structure, characteristics and effects according to the utility model with reference to the attached drawings and the preferred embodiment.
As shown in fig. 1, a hoisting device for a narrow space comprises a measuring mechanism 1, a base frame 2 and a hoisting tool 3; the base frame 2 is erected above the reserved opening 4, the suspension end of the lifting appliance 3 penetrates through the reserved opening 4 to lift an object at the lower layer of the building, and the measuring mechanism 1 is used for measuring whether the installation position of the base frame 2 is proper or not. If the position of the base frame 2 deviates, the base frame 2 collapses or tilts due to the stress deflection of the device, and the dangling articles swing, fall and the like are caused.
As shown in fig. 2, in the process of installing the base frame 2, it is required to consider that the stress point of the whole base frame 2 should be located at the center of the base frame, so as to ensure that the device with simple structure does not disintegrate or incline. Therefore, when the base frame 2 is mounted, attention is paid to the positional relationship between the mounting position of the base frame 2 and the reserved opening 4. In an embodiment, the base frame 2 includes two bases 201, two supporting frames 202 and a supporting beam 203, wherein the two bases 201 are respectively and fixedly connected with one ends of the two supporting frames 202, and the two supporting frames 202 are fixedly connected with the supporting beam 203; two base 201 install respectively in reserve mouthful 4 both sides, be convenient for follow-up measurement and hoisting work for measuring mechanism 1's effect is better.
As shown in fig. 2, in the use process of the base frame 2, the supporting strength and the structural hanging stability of the base frame 2 are to be ensured, in an embodiment, an upper haunching plate 5 is disposed at the connection position of any one of the supporting frames 202 and the supporting beam 203, specifically, the supporting frames 202 and the supporting beam 203 are fixedly connected to form a 90 ° included angle, the upper haunching plate 5 has a triangular structure, and the connection positions of the two right-angle sides of the upper haunching plate 5 and the supporting frames 202 and the supporting beam 203 are welded and reinforced respectively, so that when the supporting beam 203 suspends objects, the supporting effect of the supporting frames 202 on the supporting beam 203 is enhanced.
As shown in fig. 2, similarly, the connection part between any support frame 202 and the base 201 is provided with a lower haunching plate 6, specifically, the lower haunching plate 6 is welded and fixed with the base 201 and the support frame 202, so that the structural stability of the base frame 2 is enhanced, and the stable supporting effect can be achieved while the structure is simple.
