Description

Technical Field

[0001] This utility model relates to a suspension device, specifically a multi-functional safety suspension device for concrete structures. Background Technology

[0002] In the field of power construction, especially in thermal power projects and substation construction, high-support formwork and large-span concrete structures have been widely used due to their advantages such as high load-bearing capacity, high construction efficiency, strong environmental adaptability, and outstanding safety and reliability. This structural form can effectively support the installation and operation of large equipment, while improving the overall construction progress. However, with the increase in structural height and span, a series of safety and efficiency issues have gradually emerged, becoming the core factors restricting construction safety and efficiency.

[0003] In the construction of secondary structure masonry and exterior wall insulation coating of high-formwork, large-span concrete structures, the large span, high floor height, and few attached components limit the availability of sufficient anchoring points for safety belts and ropes, leading to significant defects in material transportation. For example: 1. Manual handling: In the erection of structural columns and ring beam formwork, the vertical transportation of assembled formwork is mostly done manually, resulting in low construction efficiency and high labor intensity. 2. Scaffolding: While this method reduces risk, it consumes a large amount of manpower and resources for material transportation, making it uneconomical and extending the construction period. 3. Lifting: For coating and installation projects on large-span, high-rise buildings, vertical transportation of tools and loose materials (such as formwork, reinforcements, mortar, and putty) using lifting is convenient, but the excessive height above the ground increases the risk of instability and overturning.

[0004] In summary, existing methods of vertical material transportation suffer from problems such as insufficient safety assurance, low construction efficiency, high labor intensity, and high construction costs. Utility Model Content

[0005] The present invention aims to provide a multi-functional safety suspension device for concrete structures to solve the problems of insufficient safety assurance, low construction efficiency, high labor intensity and high construction cost of existing vertical material transportation methods.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-functional safety suspension device for concrete structures includes a fixed rod and a hoisting mechanism disposed at the end of the fixed rod. The hoisting mechanism includes a hoisting pulley for a rope to pass over to lift a heavy object. A first locking member and a second locking member are detachably disposed on the fixed rod, and the first locking member and the second locking member form a locking space for locking the wall.

[0007] As a limitation of this utility model: the first locking member and the second locking member have the same structure, the first locking member is a nut; the fixing rod is provided with external threads, and both the first locking member and the second locking member are threaded onto the fixing rod.

[0008] As a further limitation of this utility model: a set of gasket assemblies is respectively provided on the fixing rod near the first locking member and the second locking member, and each set of gasket assemblies includes a flat gasket and a spring gasket.

[0009] As another limitation of this utility model: a limiting component can be detachably provided at the end of the fixed rod away from the hoisting mechanism, and the first locking component and the second locking component are located between the hoisting mechanism and the limiting component.

[0010] As a further limitation of this utility model: the limiting member includes a positioning pin and a cotter pin that is inserted and fixed to the positioning pin; an anti-disassembly locking hole is provided on the end of the fixing rod away from the hoisting mechanism, and the positioning pin passes through the anti-disassembly locking hole and is clearance-fitted with the anti-disassembly locking hole.

[0011] As another limitation of this utility model: the hoisting mechanism also includes a safety buckle, a connecting ring is fixedly provided at the end of the fixed rod, the safety buckle is detachably connected to the connecting ring, and the hoisting pulley is movably connected to the safety buckle.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: This utility model includes a fixed rod and a hoisting mechanism. The hoisting pulley in the hoisting mechanism is used for the rope to pass through. By pulling down one end of the rope, the hoisting pulley rotates, causing the weight at the other end of the rope to rise, thus realizing the vertical transportation of materials. Compared with manual handling, this method has high construction efficiency and low labor intensity. In this invention, the fixing rod is detachably equipped with a first locking member and a second locking member, which together form a locking space for securing the rod to the wall. During implementation, the fixing rod is passed through a pre-drilled hole in the wall (parapet wall or frame beam), and then secured to both sides of the wall using the first and second locking members. This ensures the fixing rod is firmly fixed and remains stable during subsequent hoisting, preventing instability and overturning, thus improving safety. This device has a simple structure and saves manpower and resources compared to scaffolding, resulting in lower costs.

[0013] In summary, this utility model has good stability and high safety, as well as high construction efficiency, low labor intensity, and low construction cost. This utility model is suitable for the vertical transportation of materials in the construction of high-formwork and large-span concrete structures. Attached Figure Description

Detailed Implementation

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and do not constitute a limitation thereof.

[0018] like Figures 1-5 As shown, this embodiment includes a fixing rod 1 and a hoisting mechanism 2 disposed at the end of the fixing rod 1. The fixing rod 1 is used for fixing through the wall, and the hoisting mechanism 2 is used for hoisting the material to achieve vertical transportation of the material.

[0019] The fixing rod 1 is made of round steel with a diameter of 18mm and a length of 70cm. A first locking element 3 and a second locking element 4 are detachably mounted on the fixing rod 1, forming a locking space between them for securing it to the wall. During installation, the fixing rod 1 is passed through a pre-drilled hole in the wall (parapet wall or frame beam), and then secured to both sides of the wall using the first locking element 3 and the second locking element 4, ensuring the fixing rod 1 is firmly fixed and stable during subsequent hoisting.

[0020] like Figure 1 , 2 As shown, in this embodiment, the first locking member 3 and the second locking member 4 have the same structure, both using nuts. The fixing rod 1 is provided with external threads. Figure 1-3The external thread on the fixing rod 1 is not shown. Both the first locking element 3 and the second locking element 4 are threaded onto the fixing rod 1. The distance between the nuts is adjusted by tightening the two nuts to accommodate walls of different thicknesses. By securing the fixing rod 1 to both sides of the wall using the first locking element 3 and the second locking element 4, the fixing rod 1 is firmly fixed and remains stable during subsequent hoisting, preventing instability and overturning, thus improving safety.

[0021] Of course, the first locking element 3 and the second locking element 4 can also be replaced with another structure. For example, two slotted holes with a certain interval can be opened along the axial direction of the fixing rod 1, and a bolt can be inserted into each slotted hole. The bolts are fixed in position within the slotted holes by using nuts. For thicker walls, the nuts are loosened, causing the two bolts to slide back and forth within their respective slotted holes, increasing the distance between the two bolts. After they move into position, the nuts are tightened to prevent the bolts from moving further. For thinner walls, the relative movement of the two bolts within the slotted holes can be adjusted.

[0022] like Figure 1 , 2 As shown, a set of washer assemblies is fitted on the fixing rod 1 near the first locking member 3 and the second locking member 4. Each washer assembly includes a flat washer 5 and a spring washer 6. The structure of the flat washer 5 and the spring washer 6 is existing technology. During on-site construction, the flat washer 5 and the spring washer 6 are located between the first locking member 3 and the wall, and between the second locking member 4 and the wall; the flat washer 5 is used to increase the force-bearing area of ​​the nut, while the spring washer 6 plays a buffering and protective role.

[0023] Furthermore, to further ensure the stability of the fixing rod 1, a limiting component can be detachably installed at the end of the fixing rod 1 away from the hoisting mechanism 2. The first locking component 3 and the second locking component 4 are located between the hoisting mechanism 2 and the limiting component. When the second locking component 4 slips, the limiting component can prevent the fixing rod 1 from coming out of the reserved hole, causing the device to tip over and causing safety problems.

[0024] like Figure 5 As shown, the limiting component includes a locating pin 7 and a cotter pin 8 that is inserted and fixed to the locating pin 7. The cooperation between the locating pin 7 and the cotter pin 8 is existing technology. Figure 1 , 2 As shown, the end of the fixing rod 1 furthest from the lifting mechanism 2 is provided with an anti-disassembly locking hole 9. The positioning pin 7 passes through the anti-disassembly locking hole 9 and is clearance-fitted with it. In use, the positioning pin 7 is passed through the anti-disassembly locking hole 9, and then the cotter pin 8 is inserted to achieve fixation. Even if the second locking member 4 slips, the limiting member can ensure that the fixing rod 1 will not come out of the reserved hole, further ensuring the stability of the lifting.

[0025] like Figure 1As shown, the lifting mechanism 2 includes a lifting pulley 21 around which a rope passes to lift the heavy object. The lifting pulley 21 has a prior art structure, is made of high-quality carbon steel, and possesses excellent performance in terms of strength, toughness, and wear resistance, meeting the mechanical performance requirements of this device. Figure 3 , 4 As shown, the lifting pulley 21 includes a U-shaped sleeve 211 and a pulley 212 rotatably mounted on the U-shaped sleeve 211, with the pulley 212 located within the U-shaped groove. The lifting mechanism 2 also includes a safety buckle 22, which is an existing O-ring safety buckle made of high-quality carbon steel, possessing excellent strength, toughness, and wear resistance, meeting the mechanical performance requirements of this device. Figure 1 , 4 As shown, a connecting ring 10 is fixedly provided at the end of the fixed rod 1. The safety buckle 22 is detachably connected to the connecting ring 10, facilitating omnidirectional rotation. In this embodiment, the connecting ring 10 is teardrop-shaped and integrally connected to the fixed rod 1. That is, the end of the fixed rod 1 is bent into the connecting ring 10 by a bending machine, and the folded-back end is welded and fixed to the fixed rod 1. The lifting pulley 21 is movably connected to the safety buckle 22, that is, the U-shaped sleeve 211 is movably fitted onto the safety buckle 22.

[0026] In this embodiment, the surface of the hoisting pulley 21 and the connecting ring 10 is coated with red lead anti-rust and anti-corrosion paint, which can not only effectively prevent corrosion and rust and extend the service life of the device, but also serve as a safety warning through the eye-catching color, thereby improving the safety management level of the construction site.

[0027] In this embodiment, the fixing rod 1 is passed through the pre-drilled hole in the wall (parapet wall or frame beam), and then secured to both sides of the wall using the first locking member 3 and the second locking member 4 to fix the fixing rod 1, after which hoisting begins. This embodiment has two implementation forms: First, the use of safety buckle 22; safety buckle 22 is directly connected to the horizontal safety rope or vertical safety rope to realize the tying operation of the horizontal safety rope and vertical safety rope; safety buckle 22 can also be used to hoist and fix the pouring hose of the secondary structure ring beam and structural column. Second, the use of hoisting pulley 21; hoisting pulley 21 is used to realize the vertical transportation of tools and loose short materials (such as formwork, reinforcement parts, mortar, putty, etc.) during the secondary structure construction stage and decoration construction stage.

[0028] This embodiment has a simple overall structure, saving manpower and resources compared to setting up scaffolding, resulting in lower costs. Furthermore, compared to manual handling, this embodiment offers higher construction efficiency and lower labor intensity.

[0029] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
