Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically a balance distribution beam for hoisting steel structure components. Background Technology

[0002] In current steel structure component hoisting operations, the problems of unbalanced hoisting and uneven load distribution are very prominent. In the construction field, such as the construction of high-rise steel structure buildings, if the hoisting points of steel beams and other components are not set properly, the components will tilt during the hoisting process. This tilting will not only cause the components to collide with the surrounding existing structures or other obstacles during the ascent, causing scratches and deformation on the surface of the components, but also affect the subsequent installation accuracy and overall structural stability. Therefore, in order to achieve balanced hoisting of objects, the hoisting equipment is generally equipped with a balance distribution beam, so that the objects can be hoisted smoothly and safely.

[0003] Furthermore, the existing balance distribution beam has obvious defects in its structural design. Before lifting, the hook needs to be fixed in the preset installation hole of the balance distribution beam, and the hook and the installation hole need to be firmly connected by fasteners such as screws, nuts, and spring washers. During the lifting operation, in order to ensure the weight balance of the lifted object, the fixed point of the hook needs to be adjusted multiple times. Each adjustment requires repeated disassembly and reassembly of the above fasteners, which makes the operation process cumbersome and tedious, and seriously reduces the efficiency of the lifting operation.

[0004] Therefore, it is necessary to provide a new balanced distribution beam for hoisting steel structure components to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a balance distribution beam for hoisting steel structure components, which allows for convenient and fast adjustment of hook positions and effectively improves hoisting efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides a balance distribution beam for hoisting steel structure components, comprising: a portal-shaped main beam and a secondary beam. The secondary beam is fixedly installed inside the portal-shaped main beam. A lifting ring is fixedly installed on the top of the portal-shaped main beam.

A positioning mechanism is provided on each of the two sliding arms, and the positioning mechanism is adapted to the positioning holes.

[0007] Furthermore, in both of the positioning mechanisms, each positioning mechanism includes a connecting arm, which is fixedly installed on the top of the corresponding sliding arm.

All four point insertion rods are inserted into the corresponding point holes. A wedge-shaped abutment block is fixedly installed at the top of each of the two guide rods. A fastening screw is threaded onto the top of the connecting bracket, and an inverted U-shaped support is rotatably installed at the bottom end of the fastening screw. The bottom sides of the inverted U-shaped support are both arc surfaces, and the two arc surfaces contact the two wedge-shaped abutment blocks respectively. A connecting ring is fixedly sleeved on each of the two guide rods, and a return spring is sleeved on each of the two guide rods.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figures 1-6 .

[0017] The balance distribution beam for hoisting steel structure components includes a portal-shaped main beam 1 and a secondary beam 3. The secondary beam 3 is fixedly installed inside the portal-shaped main beam 1. To improve the stability between the portal-shaped main beam 1 and the secondary beam 3, multiple reinforcing ribs are fixedly installed on both sides of the secondary beam 3. The tops of the multiple reinforcing ribs are fixedly connected to the top inner wall of the portal-shaped main beam 1. A lifting ring 2 is fixedly installed on the top of the portal-shaped main beam 1. Two sliding arms 4 are slidably installed on the secondary beam 3. An installation block 5 is fixedly installed at the bottom of each of the two sliding arms 4. An installation socket 6 is opened at the bottom of each of the two installation sockets 5. A positioning block 7 is fixedly installed in each of the two installation sockets 6 by bolts. A hook 8 is fixedly installed at the bottom of each of the two positioning blocks 7. The tops of the two sliding arms 4 extend above the portal-shaped main beam 1 and are slidably connected to the portal-shaped main beam 1. To facilitate and quickly adjust the hoisting point of the hook 8, multiple positioning holes 9 are opened on the secondary beam 3. A fixing mechanism is provided on each of the two sliding arms 4, and the fixing mechanism is adapted to the positioning hole 9.

[0018] In both of the aforementioned positioning mechanisms, each includes a connecting arm 10, which is fixedly mounted on the top of the corresponding sliding arm 4. A connecting bracket 11 is fixedly mounted on the top of the connecting arm 10. Guide rods 12 are slidably mounted on both sides of the connecting bracket 11. Linkage plates 13 are fixedly mounted on the ends of the two guide rods 12 that are far apart from each other. To ensure that the linkage plates 13 do not rotate, sliding rods are fixedly mounted on both sides of the connecting arm 10. The two sliding rods pass through the two linkage plates 13 respectively and are slidably connected to the corresponding linkage plates 13. Two point-positioning rods 14 are fixedly mounted on the side of the two linkage plates 13 that are close to each other. All four point-positioning rods 14 are... Insert into the corresponding point hole 9 to form a fixed position effect. Wedge-shaped abutment blocks 15 are fixedly installed at the top of the two guide rods 12. Fastening screws 16 are threaded on the top of the connecting bracket 11. Inverted U-shaped supports 17 are rotatably installed at the bottom of the fastening screws 16. The bottom of both sides of the inverted U-shaped supports 17 are set as arc surfaces. The two arc surfaces contact the two wedge-shaped abutment blocks 15 respectively. Connecting rings 18 are fixedly sleeved on the two guide rods 12. Return springs 19 are sleeved on the two guide rods 12. The ends of the two return springs 19 that are close to each other are fixedly connected to the two connecting rings 18 respectively. The ends of the two return springs 19 that are far apart from each other are fixedly connected to the inner walls of both sides of the connecting bracket 11 respectively.

[0019] In the above method, in order to improve the fastening force of the fastening screw 16, a screw head is fixedly installed at the top of the fastening screw 16, and a spring washer is sleeved on the fastening screw 16. The spring washer is located between the screw head and the connecting bracket 11. Two limit rods are slidably installed on the top of the connecting bracket 11, and the bottom ends of the two limit rods are fixedly connected to the inverted U-shaped support 17.

[0020] In this embodiment, in order to further improve the stability of the sliding arm 4, four guide rails are fixedly installed on the top of the portal main beam 1, and sliders are slidably installed on each of the four guide rails. The tops of the four sliders are fixedly connected to the corresponding connecting arms 10.

[0021] The working principle of the balance distribution beam for hoisting steel structure components provided by this utility model is as follows: Initially, the return spring 19 is in a stretched state; When in use, first connect and fix the entire balance distribution beam to the external lifting equipment through the lifting ring 2 at the top of the portal main beam 1 to ensure the stability of the connection between the lifting ring 2 and the lifting equipment; According to the weight distribution, size specifications and preset lifting point position of the steel structure component to be hoisted, loosen the fastening screw 16 of the positioning mechanism to separate the inverted U-shaped support 17 from the wedge-shaped contact block 15, and the stretched return spring 19 returns to its original position, so that the point insertion rod 14 moves out of the point hole 9. At this time, the two sliding arms 4 can be adjusted horizontally along the guide rails at the top of the sub-beam 3 and the portal main beam 1. When the distance between the two sliding arms 4 is adjusted by sliding, the mounting block 5 moves synchronously with the sliding arm 4, thereby driving the positioning block 7 and the hook 8 to adjust their positions until the two hooks 8 are precisely aligned with the preset lifting point of the component to be lifted, ensuring that the component is balanced under force when it is lifted. Once the hook 8 is in position, rotate the screw head at the top of the fastening screw 16 to drive the fastening screw 16 to spiral downward along the connecting bracket 11. The inverted U-shaped support 17 then moves downward, and the arc surfaces at the bottom of its two sides contact the two wedge-shaped contact blocks 15 and generate a squeezing force, forcing the two guide folding rods 12 to slide along the connecting bracket 11 towards each other. When the guide folding rods 12 slide, they drive the linkage plate 13 to move synchronously, so that the point insertion rod 14 on the linkage plate 13 is inserted into the corresponding point hole 9 of the sub-beam 3, thereby locking the position of the sliding arm 4. At the same time, the connecting ring 18 on the guide folding rod 12 pulls the return spring 19, causing the return spring 19 to be in a stretched state. Thus, the goods can be hoisted. During the hoisting process, the weight of the steel structure component to be hoisted is evenly transmitted to the lifting ring 2 through the hook 8, mounting block 5, sliding arm 4, sub-beam 3 and portal main beam 1, thereby achieving a balanced distribution of the load. When the lifting point needs to be adjusted, simply rotate the screw head of the fastening screw 16 in the opposite direction. This will cause the fastening screw 16 to move the inverted U-shaped support 17 upward. The squeezing force of the inverted U-shaped support 17 on the wedge-shaped contact block 15 will disappear, the return spring 19 will return to its original position, and the linkage plate 13 will drive the point insertion rod 14 to be pulled out from the point hole 9, releasing the position lock of the sliding arm 4. Then, repeat the aforementioned point adjustment steps to quickly adjust the position of the sliding arm 4 and the hook 8. There is no need to repeatedly disassemble the connection structure between the mounting block 5 and the positioning block 7, which greatly simplifies the adjustment process and improves the efficiency of the lifting operation.

[0022] Compared with related technologies, the balance distribution beam for hoisting steel structure components provided by this utility model has the following beneficial effects: I. This utility model eliminates the need for repeated disassembly of the connection structure between the mounting block 5 and the positioning block 7. The insertion and removal of the point insertion rod 14 and the locking / unlocking of the sliding arm 4 can be completed simply by rotating the fastening screw 16, which greatly simplifies the point adjustment process of the hook 8 and improves the efficiency of hoisting operations. Second, this utility model utilizes the precise cooperation between the multiple point holes 9 of the secondary beam 3 and the point insertion rod 14, combined with the locking effect of the fastening screw 16, to ensure that the sliding arm 4 does not shift unexpectedly after being locked, thus ensuring the balance and stability of the hoisting. In addition, the portal main beam 1 and the secondary beam 3 are reinforced and connected by reinforcing ribs to avoid structural deformation during hoisting and to extend the service life of the equipment.
