Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude construction of building construction, in particular to a safe suspension structure for high-altitude construction of building construction. Background Art

[0002] Building construction refers to the construction of houses and other structures on land where infrastructure construction has been completed, including residential buildings, industrial plants, commercial buildings, office buildings and other special-purpose houses. When construction is carried out at high altitudes on construction sites, suspended structures are often used to assist in the construction. The characteristics of building construction are large workloads at heights, complex and changeable working environments, high labor intensity of manual operations, and many dangerous factors in cross-operation of multiple trades, which makes accidents very easy to occur.

[0003] At present, the utility model with the announcement number CN219316479U proposes a safety suspension structure for high-altitude construction of building construction, including a wall, a fixed plate is fixedly installed on the left side of the wall by bolts, two mounting plates are fixedly connected to the left side of the fixed plate, two slide rails are fixedly connected to the left side of the fixed plate, both slide rails are slidably connected to sliders, a moving plate is fixedly connected between the left sides of the two sliders, a fixed frame is fixedly connected to the left side of the moving plate, and a connecting plate is fixedly installed on the left side of the wall and located at the top of the fixed plate by bolts. The safety suspension structure for high-altitude construction of building construction conveniently drives the moving plate to move through the sliding connection between the slide rail and the slider, improves the stability of the moving plate, improves the stability of the mounting plate and the fixed frame under the action of the first support plate and the second support plate, further improves the stability of the suspension structure, and is more convenient to use.

[0004] However, the above-mentioned prior art still has the following deficiencies in actual use: 1. When the take-up drum is started and stopped, the objects suspended on it by the rope will generate a large impact force due to inertia, and this impact force will affect the safety of the entire suspension structure; 2. When the take-up drum is in the process of winding the wire, the rope is prone to fixed-point winding, that is, the winding on the take-up drum is prone to aggregation and expansion, and it is difficult to spread it axially, which easily leads to the problem of tension and collapse of the rope when the take-up drum is winding and releasing the wire. The tension and collapse will form an impact, and also accelerate the wear of the rope, affecting the service life of the rope.

[0005] To this end, the utility model provides a safe suspension structure for high-altitude construction of building construction. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a safe suspension structure for high-altitude construction of building construction, comprising a fixed plate 1, a movable plate 2 located on one side of the fixed plate 1, and a wire take-up drum 3 located on one side of the movable plate 2, wherein the sliding matching structure of the movable plate 2 and the fixed plate 1 and the movement control function of the movable plate 2 can adopt the structure of the prior art mentioned in the background technology, when in use, the fixed plate 1 is installed on the wall, two ear plates can be welded on one side of the fixed plate 1, the wire take-up drum 3 is rotatably connected between the two ear plates, a retractable control motor is installed on one of the ear plates, and the output shaft of the retractable control motor is fixedly connected to the wire take-up drum 3 to realize the rotation control of the wire take-up drum 3.

[0023] In the present technical solution, one side of the movable plate 2 is provided with an elastic buffer rod 4 which is laterally slidably connected to the bottom of the take-up drum 3. The free end of the elastic buffer rod 4 is provided with a reversing wheel 5. The rope hanging down on the take-up drum 3 passes through the wheel groove on the reversing wheel 5. When the rope is loaded, the elastic buffer rod 4 is elastically compressed.

[0024] Specifically, the elastic buffer rod 4 includes a guide sleeve 41, a shock absorbing spring 42 and a guide shaft 43. One end of the guide shaft 43 is sleeved in the guide sleeve 41 and is a damping sliding fit. The specific implementation structure is that a rubber sleeve 9 is nested in the guide sleeve 41, and the guide shaft 43 is sleeved in the rubber sleeve 9. A wheel seat 431 connected to the reversing wheel 5 is welded to the other end of the guide shaft 43, and a sliding seat 411 slidably connected to the moving plate 2 is welded to one end of the guide sleeve 41. The shock absorbing spring 42 is sleeved on the outside of the guide sleeve 41 and the guide shaft 43. When the guide shaft 43 is axially squeezed, the shock absorbing spring 42 will be compressed. The structure of the slide 411 and the movable plate 2 is that a slider 4111 is welded to one side of the slide 411, a guide groove 21 slidably matched with the slider 4111 is opened on one side of the movable plate 2, a support plate 22 located below the guide groove 21 is welded to one side of the movable plate 2, and a roller 4112 is provided at the bottom of the slide 411 to abut against the top of the support plate 22. When the support plate 22 lifts the roller 4112, the smoothness of the sliding of the slide 411 relative to the movable plate 2 can be improved.

[0025] One side of the moving plate 2 is also rotatably connected with a reciprocating screw 6 that is screwed with the elastic buffer rod 4. When the reciprocating screw 6 rotates, it drives the elastic buffer rod 4 to slide back and forth horizontally. Specifically, the middle part of the slide 411 is penetrated and fixed with a wire sleeve 4113 sleeved on the reciprocating screw 6. When the reciprocating screw 6 rotates, it drives the wire sleeve 4113 to reciprocate. A transmission assembly 7 is arranged between the take-up drum 3 and the reciprocating screw 6, that is, when the take-up drum 3 rotates, the reciprocating screw 6 is driven to rotate through the transmission assembly 7. When the elastic buffer rod 4 moves back and forth horizontally, the position of the rope in contact with the take-up drum 3 in the axial direction is changed, so that the rope can be evenly wound on the take-up drum 3. The specific implementation structure is that a transmission shaft 31 is welded at one end of the take-up drum 3, and the transmission assembly 7 includes a gear 1 71 and a gear 2 72. The gear 1 71 is fixedly connected to one end of the transmission shaft 31, and the gear 2 72 is fixedly connected to one end of the reciprocating screw 6 and meshes with the gear 1 71. When the take-up drum 3 rotates, it can provide a rotational driving force to the reciprocating screw 6 through the transmission assembly 7.

[0026] In this embodiment, a portal frame 4311 is welded to one side of the wheel seat 431, a positioning shaft 43111 is welded inside the portal frame 4311, and a reversing wheel 5 is sleeved on the crossbeam 43112 of the portal frame 4311 and the positioning shaft 43111. The reversing wheel 5 on the crossbeam 43112 and the positioning shaft 43111 serves to limit the rope and prevent the rope from slipping out of the groove.

[0027] In this embodiment, one side of the slide 411 is fixedly connected to a wheel frame 8 located below the elastic buffer rod 4, and the wheel frame 8 is provided with two reversing wheels 5 that are in the same plane and have parallel axes. The two reversing wheels 5 also play a role in limiting the rope, ensuring that the rope is not affected by the extension and retraction action of the elastic buffer rod 4, so that the objects at the bottom of the rope are in a stably suspended state.

[0028] Working principle: after the object is hung by the hook at the bottom of the rope, the take-up drum 3 is controlled to rotate, and the take-up drum 3 starts to wind the rope. At the same time, the transmission shaft 31 will drive gear 1 71 to rotate, gear 1 71 drives gear 2 72 to rotate, and gear 2 72 drives the reciprocating screw 6 to rotate, and the entire elastic buffer rod 4 will move laterally to guide the winding of the rope. When the force on the rope increases, the guide shaft 43 slides into the guide sleeve 41, and the shock-absorbing spring 42 is compressed. After the object is lifted, the elastic buffer rod 4 is in a stable state. When the take-up drum 3 stops rotating, the elastic buffer rod 4 will expand and contract slightly to buffer the impact force when the object stops, so that the overall suspension structure has suspension buffering function and rope guiding function, which improves the stability and safety of the use of the suspension structure.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
