Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a foldable steel pipe hoisting frame for building construction. Background Technology
[0002] Traditional steel pipe hoisting frames used in construction are typically fixed in structure and bulky in size. They occupy a lot of space during transportation, increasing transportation costs and difficulties. Their installation and dismantling often require specialized equipment and a large amount of manpower, which is not only time-consuming and labor-intensive, but may also pose safety hazards due to improper operation. Fixed hoisting frames are difficult to adjust according to different construction sites and operation requirements, thus limiting their applicability.
[0003] Patent document CN221544013U discloses a steel pipe lifting frame, including a base and a support frame. Two sliding grooves are formed through the upper surfaces of both bases. The inner walls of both ends of the two sliding grooves are rotatably connected to bidirectional lead screws, and the outer walls of both ends of the bidirectional lead screws are threaded with nuts. This lifting frame can only improve the stability of steel pipe transportation and prevent unnecessary damage caused by pipe swaying. It does not allow for the folding of steel pipes for use, and still suffers from problems such as large space occupation, high transportation and storage costs, and low flexibility in subsequent use. Utility Model Content
[0004] The purpose of this invention is to provide a foldable steel pipe hoisting frame for building construction, which solves the problems of large space occupation and low flexibility.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A foldable steel pipe hoisting frame for building construction includes two hoisting frame vertical rods 1, two hoisting frame vertical rods 2, a crossbeam, a supporting crossbeam, and a manual hoist. The two hoisting frame vertical rods 1 are vertically spaced apart and their top ends are fixedly connected by the crossbeam. The manual hoist is provided in the middle of the crossbeam. The hoisting frame vertical rods 2 are hinged to the bottom end of the hoisting frame vertical rods 1 by a hinge assembly. The bottom ends of the two hoisting frame vertical rods 2 are fixedly connected by the supporting crossbeam. A support block is provided at the bottom end of the hoisting frame vertical rods 2. In the non-folded state, the lifting frame vertical rod one and the lifting frame vertical rod two are temporarily fixed and supported at the hinge by locking the fixing block; in the folded state, the lifting frame vertical rod one and the lifting frame vertical rod two are fixed by suction components by releasing the fixing block.
[0006] Preferably, the hinge assembly includes two hinged fixing plates, one of which is fixedly connected to the bottom of the first vertical rod of the hoisting frame, and the other fixing plate is fixedly connected to the top of the second vertical rod of the hoisting frame.
[0007] Preferably, a plurality of threaded holes are evenly spaced on the fixing plate, and bolts are passed through the threaded holes to connect to the first or second vertical rod of the hoisting frame.
[0008] Preferably, threaded holes adapted to the bolts are provided at the bottom of the first vertical rod of the hoisting frame and at the top of the second vertical rod of the hoisting frame.
[0009] Preferably, a slot is provided on both sides of the first hoisting rod and both sides of the second hoisting rod, which forms a sliding groove after being hinged. The fixing block is slidably installed in the sliding groove. The fixing block can be fixed in the sliding groove by fasteners and is located at the joint of the first hoisting rod and the second hoisting rod.
[0010] Preferably, the fixing block is U-shaped, and a protrusion that matches the sliding groove is provided on each of the two inner sides of the fixing block.
[0011] Preferably, the attraction assembly includes two N-pole magnetic blocks and two S-pole magnetic blocks. The two N-pole magnetic blocks are respectively arranged at the top rear of the two lifting frame vertical rods one, and the two S-pole magnetic blocks are respectively arranged at the bottom rear of the two lifting frame vertical rods two. When the lifting frame vertical rods one and two are in a folded state, the N-pole magnetic blocks and the S-pole magnetic blocks are attracted together.
[0012] Preferably, a fixing beam is used to reinforce the space between the two lifting frame vertical rods.
[0013] Preferably, a threaded hole for temporarily fastening the fixing block is provided at the bottom front of the first hoisting rod and at the top front of the second hoisting rod.
[0014] In this invention, the hinge assembly allows the steel pipe hoisting frame to be folded flexibly, facilitating transportation and storage, reducing space occupation, and lowering transportation and warehousing costs.
[0015] The steel pipe hoisting frame is easy to install and dismantle, which improves construction efficiency, reduces labor costs, and enhances installation and dismantling efficiency.

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-4 The foldable steel pipe hoisting frame for building construction shown includes two hoisting frame vertical rods 1, two hoisting frame vertical rods 2, a horizontal beam 3, a supporting horizontal beam 4, and a manual hoist 5.
[0019] Two vertical lifting frame rods 1 are set vertically at intervals and their top ends are fixedly connected by a horizontal beam 3. A manual hoist 5 is installed in the middle of the horizontal beam 3. In order to increase the strength of the steel pipe lifting frame, a fixing beam 11 is also used to reinforce the two lifting frame rods 1. The fixing beam 11 can also be used to assist in the installation of some lifting-related accessories or ropes.
[0020] A second vertical rod 2 of the hoisting frame is hinged to the bottom of the first vertical rod 1 via a hinge assembly 6. The bottoms of the two second vertical rods 2 are fixedly connected by a support beam 4. A support block 8 is provided at the bottom of the second vertical rod 2 to ensure the stability of the steel pipe hoisting frame. In this example, the hinge assembly 6 includes two hinged fixing plates 60. One fixing plate 60 is fixedly connected to the bottom of the first vertical rod 1, and the other fixing plate 60 is fixedly connected to the top of the second vertical rod 2. Multiple threaded holes are evenly spaced on the fixing plates 60, and bolts 61 pass through the threaded holes to connect to the first vertical rod 1 or the second vertical rod 2. Threaded holes adapted to the bolts 61 are provided at the bottom of the first vertical rod 1 and the top of the second vertical rod 2.
[0021] In the non-folded state, the locking block 7 provides temporary support at the hinge joint of the lifting frame vertical rod 1 and the lifting frame vertical rod 2. A slot is provided on both sides of the lifting frame vertical rod 1 and the lifting frame vertical rod 2, forming a sliding groove 10 after hinge. The locking block 7 is slidably installed within the sliding groove 10. The locking block 7 can be fixed within the sliding groove 10 by fasteners and is located at the joint of the lifting frame vertical rod 1 and the lifting frame vertical rod 2, thus achieving temporary support for the lifting frame vertical rod 1 and the lifting frame vertical rod 2. The cooperation between the sliding groove 10 and the slider 9 also ensures the flexibility and ease of installation of the steel pipe lifting frame. In this example, the locking block 7 is U-shaped, and a protrusion 70 that matches the sliding groove 10 is provided on both inner sides of the locking block 7. A threaded hole for temporarily fastening the locking block 7 is provided at the bottom front of the lifting frame vertical rod 1 and the top front of the lifting frame vertical rod 2. The locking block 7 is temporarily fixed at the threaded hole by fasteners.
[0022] In the folded state, by releasing the fixing block 7, the lifting frame vertical rod 1 and the lifting frame vertical rod 2 are attracted and fixed together by the attraction assembly 9. In this example, the attraction assembly 9 includes two N-pole magnetic blocks 90 and two S-pole magnetic blocks 91. The two N-pole magnetic blocks 90 are respectively arranged at the top rear of the two lifting frame vertical rods 1, and the two S-pole magnetic blocks 91 are respectively arranged at the bottom rear of the two lifting frame vertical rods 2. When the lifting frame vertical rods 1 and 2 are in the folded state, the N-pole magnetic blocks 90 and the S-pole magnetic blocks 91 are attracted together.
[0023] Working principle: The hinge assembly 6 is used to realize the folding function between the lifting frame vertical rod 1 and the lifting frame vertical rod 2 15, and then the manual hoist 3 is used to complete the lifting operation of the steel pipe.
[0024] The steel pipe hoisting frame is initially folded for easy transportation and storage. When needed, the hoisting frame vertical rod 1 and the hoisting frame vertical rod 2 are unfolded. After unfolding, the fixing block 7 is slid to the joint of the hoisting frame vertical rod 1 and the hoisting frame vertical rod 2. Then, the fixing block 7 is fixed to the hoisting frame vertical rod 1 and the hoisting frame vertical rod 2 respectively with fasteners, which further enhances the overall stability of the steel pipe hoisting frame. After the hoisting operation is completed, the steel pipe hoisting frame needs to be folded and stored. The fixed connection between the concave block 7 and the hoisting frame vertical rod 1 and 2 is released. Then, the concave block 7 is slid to one side along the slide groove 10. After the hoisting frame vertical rod 1 and 2 are folded, the concave block 7 is separated from the slide groove 10. Finally, the N pole magnetic block 90 on the hoisting frame vertical rod 1 and the S pole magnetic block 91 on the hoisting frame vertical rod 2 are attracted to each other to further fix the folded state.
[0025] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
