Description

Technical Field

[0001] This utility model relates to the field of prefabricated building construction technology, specifically to a prefabricated building hoisting equipment. Background Technology

[0002] Prefabricated construction is a modern construction method that involves prefabricating major building components, such as structural parts, external enclosure systems, interior systems, and equipment and pipeline systems, in a factory. These components are then transported to the construction site and quickly assembled into a complete building using reliable connection methods. This method offers advantages such as fast construction speed, energy conservation and environmental protection, controllable quality, and flexibility.

[0003] In existing technologies, when hoisting the wall panel structure of prefabricated buildings, embedded parts are usually fixed on both sides of the top of the wall panel, and then the slings of the horizontal beam structure below the boom are tied to the embedded parts to lift the wall panel structure. However, during the hoisting process, the slings may sway due to external environmental disturbances, which may cause the horizontal beam and the wall panel structure below to lose stability, thus posing a safety hazard. To address this issue, a hoisting device for prefabricated buildings is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is as follows: During the lifting process, the sling may sway due to external environmental disturbances, so the crossbeam and the wall panel structure below cannot remain stable.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A prefabricated building hoisting equipment includes a hoisting mechanism, and a positioning mechanism is provided below the hoisting mechanism;

[0007] The positioning mechanism includes two extension rods. The top of each extension rod is fixedly connected to an end plate, and each extension rod has a fastening nut threadedly connected to the upper end of its outer wall. The bottom ends of the two extension rods are jointly fixedly installed with a base plate.

[0008] The base plate has rotating disks symmetrically connected to both sides of its bottom surface. Each rotating disk has a support plate fixedly connected to one end of its side wall. The support plate is aligned with the length of the base plate. A positioning hole is provided at one end of the top surface of the rotating disk.

[0009] The lower end of the inner wall of the base plate is symmetrically slidably connected with positioning shafts, and the top ends of the two positioning shafts are fixedly connected with springs II, and the top ends of each spring II are fixedly connected to the inner wall of the base plate.

[0010] Among them, a synchronizing rod is fixedly installed on the middle of the outer wall of the two positioning shafts, and the two ends of the synchronizing rod are slidably connected along the outer wall of the base plate.

[0011] As a further embodiment of this utility model: the hoisting mechanism includes a crossbeam, and sleeves are symmetrically fixedly connected to the outer wall of the crossbeam. The inner walls of the two sleeves are respectively connected through the extension rod, and the top surface of each sleeve abuts against the bottom of the fastening nut.

[0012] As a further embodiment of this utility model: several through holes are provided on both sides of the top and bottom surfaces of the crossbeam, and the through holes on each side are arranged at equal intervals along the length direction of the crossbeam. The inner wall of the crossbeam is hollowed out, and each of the through holes extends to the hollowed-out inner side of the crossbeam. A backing plate is fixedly installed in the middle of the inner wall of the crossbeam, and the backing plate is consistent with the length direction of the crossbeam.

[0013] As a further embodiment of this utility model: the hoisting mechanism further includes an insert block, and the upper end of the inner wall of the insert block is symmetrically slidably connected with a support shaft. One end of the top of each support shaft is fixedly connected with a spring, and the other end of the spring is fixedly connected to the inner wall of the insert block.

[0014] As a further embodiment of this utility model: a connecting rod is fixedly connected to the upper end of the inner wall of the insert block and located between the two support shafts, the bottom end of the connecting rod extends to the bottom of the insert block, and a lifting lug is fixedly installed at the bottom end of the connecting rod.

[0017] The beneficial effects of this utility model are:

[0018] (1) The present invention provides a positioning mechanism under the crossbeam. The extension rod in the positioning mechanism can move up and down relative to the crossbeam, thereby driving the bottom plate down to the bottom of the hoisted object. A support plate is provided under the bottom plate. The support plate can be rotated to the bottom of the hoisted object and pressed against its bottom, thereby limiting the extension rod to the hoisted object, ensuring that the hoisted object and the upper crossbeam remain stable, thereby improving the safety during hoisting.

[0019] (2) Multiple lifting lugs are installed on the top surface and the ground of the crossbeam. The lifting lugs are used to connect the upper and lower sides. The spacing of the lifting lugs under the crossbeam can be adjusted. When hoisting objects of different sizes and shapes, by adjusting the spacing of the lifting lugs and adding different numbers of lifting lugs, the connection of the hoisted objects can be made more stable, thereby avoiding safety hazards such as shaking or falling off during the hoisting process.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-5As shown, a prefabricated building hoisting equipment includes a hoisting mechanism 1, with a positioning mechanism 2 located below the hoisting mechanism 1. The positioning mechanism 2 includes two extension rods 201. An end plate 202 is fixedly connected to the top of each extension rod 201, and a fastening nut 203 is threaded onto the upper end of the outer wall of each extension rod 201. A base plate 204 is fixedly installed at the bottom ends of both extension rods 201. Rotary discs 208 are symmetrically rotatably connected to both sides of the bottom surface of the base plate 204, and a support plate 210 is fixedly connected to one end of the side wall of each rotating disc 208. A rubber pad is provided on the top of the support plate 210 to provide friction, and the support plate 210 and the base plate 204 are aligned in the same length direction. A positioning hole 209 is provided at one end of the top surface of the rotating disk 208. The lower inner wall of the base plate 204 is symmetrically slidably connected to positioning shafts 205. Springs 206 are fixedly connected to the top ends of the two positioning shafts 205, and the top ends of each spring 206 are fixedly connected to the inner wall of the base plate 204. A synchronizing rod 207 is fixedly installed in the middle of the outer wall of the two positioning shafts 205, and both ends of the synchronizing rod 207 are slidably connected along the outer wall of the base plate 204. Figures 2-3 As shown, spring 206 pushes the positioning shaft 205 downward. When the positioning hole 209 is aligned with the positioning shaft 205, the positioning shaft 205 is inserted into the positioning hole 209, so the rotating disk 208 cannot rotate.

[0029] The hoisting mechanism 1 includes a crossbeam 101, with sleeves 102 symmetrically fixedly connected to the outer wall of the crossbeam 101. The inner walls of the two sleeves 102 are respectively connected through the extension rod 201, and the top surface of each sleeve 102 abuts against the bottom of the fastening nut 203. Figure 1 As mentioned above, the sleeve 102 is not on the same vertical plane as the object being hoisted below, so that the extension rod 201 does not contact the object being hoisted;

[0030] The top and bottom surfaces of the crossbeam 101 are provided with several through holes 103 on both sides. The through holes 103 on each side are equidistant along the length of the crossbeam 101. The inner wall of the crossbeam 101 is hollowed out, and each through hole 103 extends to the inner side of the hollowed-out surface of the crossbeam 101. A support plate 104 is fixedly installed in the middle of the inner wall of the crossbeam 101. The support plate 104 is aligned with the length of the crossbeam 101. The hoisting mechanism 1 also includes an insert block 105. Support shafts 106 are symmetrically slidably connected to the upper end of the inner wall of the insert block 105. A spring 107 is fixedly connected to one end of the top of each support shaft 106, and the other end of the spring 107 is fixedly connected to the inner wall of the insert block 105. Figure 5 As shown, spring 107 pulls the support shaft 106 to retract into the insert 105, thereby facilitating the insertion of the end of the insert 105 into the through hole 103.

[0031] A connecting rod 108 is fixedly connected to the upper inner wall of the insert 105, located between the two support shafts 106. The bottom end of the connecting rod 108 extends to the bottom of the insert 105, and a lifting lug 109 is fixedly installed at the bottom end of the connecting rod 108. A compression sleeve 110 is threaded onto the lower inner wall of the insert 105. The bottom of the compression sleeve 110 extends to the bottom of the insert 105, and a knob 111 is fixedly connected to the bottom of the compression sleeve 110. The middle parts of the compression sleeve 110 and the knob 111 are both connected through the connecting rod 108. The top end of the compression sleeve 110 is frustum-shaped, and the diameter of the top end of the compression sleeve 110 gradually increases from top to bottom. The top end of the compression sleeve 110 abuts against each support shaft 106. Figure 5 As shown, the lower end of the extrusion sleeve 110 is provided with an external thread that mates with the inner wall of the extrusion sleeve 110.

[0032] The working principle of this utility model:

[0033] When the device is in use, the slings are tied to the outside of the upper and lower lifting lugs 109. The upper sling end is connected to the boom, and the lower sling end is connected to the embedded part of the object being lifted. When installing the lifting lugs 109, the insert block 105 is inserted into the through hole 103. Then, the knob 111 is turned. Under the compression of the inner wall thread of the insert block 105, the compression sleeve 110 is pushed up along the outside of the connecting rod 108. Thus, the top of the compression sleeve 110 pushes the two support shafts 106 outward. The support shafts 106 pull the spring 107 and extend from the surface of the insert block 105. The support shafts 106 extend to the inner wall of the crossbeam 101 and provide support, so that the lower lifting lug 109 and the crossbeam 101 remain relatively fixed.

[0034] After the lower sling is connected to the embedded part, the extension rod 201 moves down along the inner wall of the sleeve 102 until the top surface of the support plate 210 is flush with the bottom surface of the hoisted object. At this time, the fastening nut 203 is tightened, and the fastening nut 203 moves along the outside of the extension rod 201 to the top of the sleeve 102, supporting the extension rod 201 and the lower base plate 204. Then, the rotating disk 208 is rotated towards the bottom of the hoisted object. After the support plate 210 rotates 90 degrees, it abuts against the bottom surface of the hoisted object. At this time, the positioning hole 209 is aligned with the positioning shaft 205. The spring 206 pushes the positioning shaft 205 downward to insert into the inner wall of the positioning hole 209. At this time, the rotating disk 208 is locked. At this time, the slight sway of the hoisted object is offset by the friction provided by the lower support plate 210. When the hoisted object sways more significantly, the extension rod 201 limits the periphery of the hoisted object.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
