Description

Technical Field

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

[0002] Construction hoisting equipment is mechanical equipment used in construction for hoisting, moving, and positioning heavy objects. Common types include tower cranes, crawler cranes, and truck cranes. It consists of hoisting, luffing, slewing, and traveling mechanisms as well as a metal structure. Through the coordinated operation of these mechanisms, it achieves operations such as lifting, moving, and transporting heavy objects. The selection of equipment must take into account factors such as the characteristics of the object being hoisted, the conditions of the construction site, and the performance parameters of the equipment. It is crucial for improving construction efficiency and reducing labor intensity.

[0003] However, existing technologies still have significant shortcomings, such as:

[0004] Existing hoisting equipment for construction has many limitations in practical applications: some equipment has a fixed structure and lacks flexible storage or folding design, resulting in a large space occupation when idle, and additional disassembly or the use of large transport vehicles is required during transportation and relocation, which is cumbersome and costly. Utility Model Content

[0005] The purpose of this utility model is to provide a hoisting device for building construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hoisting device for building construction includes a crossbeam, a leg assembly, and a hoisting assembly. The leg assembly is rotatably mounted on the crossbeam. First rotating seats are fixedly mounted at both ends of the top of the crossbeam. The leg assembly includes a main leg and a secondary leg. The main leg is rotatably mounted on the crossbeam via the first rotating seats. A clearance support is provided at the upper end of the main leg. A second rotating seat is fixedly mounted at the other end of the main leg. The angle between the second rotating seat and the main leg is 30 degrees. Connection holes are provided on the crossbeam, main leg, second rotating seat, and secondary leg. Bolts and nuts are used to connect the main leg to the crossbeam and the secondary leg, respectively, thereby providing a fixing function.

[0008] Preferably, the auxiliary support leg is rotatably provided with a support foot.

[0009] Preferably, a cushioning pad is fixedly provided at the bottom of the support foot.

[0010] Preferably, the buffer pad has anti-slip texture.

[0011] Preferably, the hoisting assembly includes a sliding seat slidably mounted on a crossbeam, the sliding seat being slidably mounted on the crossbeam via pulleys, and a hoist being rotatably mounted at the bottom of the sliding seat.

[0012] Preferably, the auxiliary support leg is fixedly provided with several handles.

[0013] Preferably, the auxiliary support leg is rotatably positioned close to the main support leg, and the connecting hole on the auxiliary support leg is positioned away from the main support leg.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The main support leg can be rotated around the first rotating seat to be parallel to the crossbeam, and the auxiliary support leg can be stored near the clearance support part of the main support leg, making the overall structure compact and greatly reducing the space occupied when idle, which is conducive to storage. At the same time, the handle on the auxiliary support leg is easy for operators to hold and move. The overall structure in the folded state is lightweight, which reduces the difficulty of transportation and relocation and improves the turnover efficiency of the equipment.

[0016] 2. The outrigger assembly forms a rotating engagement with the crossbeam via a rotating base, and with the main outrigger and the auxiliary outrigger. Combined with the corresponding connecting holes and the locking structure of bolts and nuts, it can be quickly deployed and fixed without the need for complicated tools, simplifying the operation process. The angle design between the main outrigger and the second rotating base, and the position layout of the auxiliary outrigger connecting holes, ensure the stability of the support structure after deployment, taking into account both convenience and reliability.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] The main components of the hoisting equipment used in this construction project include a crossbeam 1, a leg assembly 2, and a hoisting assembly 3. The connections, positional relationships, and working principles of each component are as follows:

[0026] The crossbeam 1 is the basic load-bearing component of the equipment and is horizontally positioned. Its cross-section is I-shaped, with a first rotating seat 11 fixed at each of its top ends. The first rotating seat 11 remains relatively fixed to the crossbeam 1, enabling a rotatable connection between the support leg assembly 2 and the crossbeam 1. The crossbeam 1 also has connecting holes 12, which mate with corresponding holes on the support leg assembly 2, allowing the support leg assembly 2 to be fixed to the crossbeam 1 after adjustment.

[0027] The support leg assembly 2 includes a main support leg 21 and a secondary support leg 22, which are rotatably connected to the crossbeam 1. One end of the main support leg 21 is rotatably engaged with the first rotating seat 11, allowing it to rotate around the axis of the first rotating seat 11, thereby switching the main support leg 21 between a retracted state parallel to the crossbeam 1 and a working state perpendicular to the crossbeam 1. The upper end of the main support leg 21 is provided with a clearance support part 211, which is adapted to the crossbeam 1. When the main support leg 21 is perpendicular to the crossbeam 1, it can be embedded therein to avoid interference between the two.

[0028] A second rotating seat 212 is fixed to the end of the main support leg 21 away from the first rotating seat 11. The orientation of the second rotating seat 212 forms a 30-degree angle with the length direction of the main support leg 21. One end of the auxiliary support leg 22 is rotatably engaged with the second rotating seat 212, allowing it to rotate around the axis of the second rotating seat 212. The main support leg 21 has a connecting hole 12 corresponding to the connecting hole 12 of the crossbeam 1, and the second rotating seat 212 and the auxiliary support leg 22 also have corresponding connecting holes 12. When the main support leg 21 is flipped to the working position perpendicular to the crossbeam 1, the crossbeam 1 and the connecting hole 12 on the main support leg 21 are aligned. The crossbeam 1 and the main support leg 21 are fixed by bolt 4 passing through and tightening with nut 5. When the auxiliary support leg 22 is flipped to the working position, the auxiliary support leg 22 and the connecting hole 12 on the second rotating seat 212 are aligned. The second rotating seat 212 and the auxiliary support leg 22 are fixed by bolt 4 and nut 5, thereby making the support leg assembly 2 form a stable support structure.

[0029] The auxiliary support leg 22 is positioned close to the main support leg 21, and the two are connected by a rotating structure, allowing the auxiliary support leg 22 to rotate around the connection point. The connecting hole 12 on the auxiliary support leg 22 is located on the side away from the main support leg 21. When the auxiliary support leg 22 is rotated around the connection point to the unfolded state, the connecting hole 12 can be aligned with the corresponding hole on the second rotating seat 212, facilitating the insertion of the bolt 4 into the hole and tightening it with the nut 5, thereby fixing the auxiliary support leg 22 to the second rotating seat 212.

[0030] Several handles 224 are fixedly provided on the side of the auxiliary support leg 22. These handles 224 are relatively fixed to the auxiliary support leg 22. The operator can apply force by holding the handles 224 to facilitate the movement of the auxiliary support leg 22 or adjust its flipping angle.

[0031] The auxiliary support leg 22, located away from the main support leg 21, is connected to a support foot 221 via a rotating structure. The support foot 221 can rotate around this connection point to adapt to different ground slopes. A buffer pad 222 is fixed to the bottom of the support foot 221, fitting snugly against it. The lower surface of the buffer pad 222 has anti-slip textures 223. When the equipment is placed on the ground, the buffer pad 222 is in direct contact with the ground. The anti-slip textures 223 increase friction with the ground, reducing slippage caused by stress during hoisting. Simultaneously, the buffer pad 222 absorbs some vibration, reducing swaying during hoisting operations and improving the overall stability of the equipment.

[0032] The hoisting assembly 3 consists of a sliding seat 31 and a hoist 32. The sliding seat 31 engages with the crossbeam 1 via pulleys 311. The pulleys 311 contact the crossbeam 1 and can roll along the crossbeam 1, causing the sliding seat 31 to move along the length of the crossbeam 1. The bottom of the sliding seat 31 is equipped with a rotating structure, through which the hoist 32 is connected to the sliding seat 31, allowing the hoist 32 to rotate around the connection point to accommodate hoisting requirements at different angles. This is used for hoisting and transferring building materials and other equipment.

[0033] In operation, the operator first adjusts the outrigger assembly 2 by flipping it off the crossbeam 1, causing the main outrigger 21, which was originally parallel to the crossbeam 1, to rotate to a position perpendicular to the crossbeam 1. At this point, the connecting holes 12 on the crossbeam 1 and the main outrigger 21 are aligned. Bolts 4 are passed through the holes and tightened with nuts 5 to lock and fix the two in place. Subsequently, the auxiliary outrigger 22 is flipped and unfolded from the main outrigger 21, aligning with the connecting holes 12 on the second rotating seat 212. Similarly, bolts 4 and nuts 5 are used to fix the two in place. At this point, the hoisting equipment is assembled and ready for operation. The operator pushes the sliding seat 31 to move it along the crossbeam 1, thereby adjusting the position of the hoist 32. The hoist 32 is then used to hoist and transfer building materials and other equipment.

[0034] In the folded state, the main support leg 21 rotates to be parallel to the crossbeam 1, while the auxiliary support leg 22 flips over and is stored near the clearance support part 211 of the main support leg 21, making the overall structure compact. At this time, the operator can move the equipment by holding the handle 224 on the auxiliary support leg 22, and the folded structure can reduce the space occupied during storage.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
