Description

Technical Field

[0001] This utility model relates to a temporary attachment device for the circulation of construction hoists. Background Technology

[0002] Existing technologies typically address the issue of construction hoists exceeding the specified wall attachment distance or having excessive free height by adding a steel structure gatehouse. Taking the SC200 / 200 construction hoist commonly used on construction sites as an example, the free end height of the hoist is limited to 7.5m. For general models using external drives, the cage height plus the drive height is approximately 4.5m. National standards require that when the upper limit switch of the construction hoist is activated, the distance from the top of the drive to the top of the guide rail should be greater than 1.8m, and the top section height should be 1.5m. Therefore, under normal circumstances, construction hoists cannot meet the requirements for rooftop access, necessitating the addition of a gatehouse frame as an attachment system.

[0003] Conventional attached gate towers are constructed using steel or secondary concrete structures. The erection of these gate towers is time-consuming and material-intensive. Furthermore, the attached gate towers must be dismantled after the construction elevators are removed. Mechanical injuries are among the most frequent and dangerous accidents in construction sites, often occurring during the structural construction phase. Therefore, some of the causes of these accidents stem from the construction hoist's attachment method being out of specification or having defects. Once an accident occurs, it can cause significant economic losses and, in severe cases, lead to the company having to suspend operations for rectification. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0027] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Reference Figure 1-4 As shown, a temporary attachment device for circulating construction hoist includes an I-beam 1; a groove 10 formed at one end of the I-beam 1; and an installation component embedded in the groove 10.

[0029] The mounting components include a pad 102, a first bolt 103 located at the center of the pad 102, a plurality of first buckles 104 symmetrically arranged on the top surface of the pad 102, a first bolt hole 101 connected to the first bolt 103 formed in the groove 10, and a slot 50 formed at one end of the vertical steel beam 5.

[0030] In order to quickly position and install the vertical steel beam 5 and the I-beam 1, the pad 102 is pre-embedded in the groove 10 before installation. Then, the first bolt 103 is inserted through the first bolt hole 101 and out through the hole in the middle of the pad 102, thereby connecting and fixing it to the vertical steel beam 5. Then, the slot 50 on the vertical steel beam 5 is spliced ​​with the first buckle 104, and the first bolt 103 is rotated to quickly install and position the vertical steel beam 5 and the I-beam 1.

[0031] An attachment steel beam 4 is set on one side of the I-beam 1, and a first limiting structure 8 is set on the top of the attachment steel beam 4 and on the adjacent side of the vertical steel beam 5. The first limiting structure 8 includes a first limiting plate 80, a second buckle 81 set on one side of the top surface of the first limiting plate 80, and a third bolt 82 set on the top surface of the first limiting plate 80 and away from the second buckle 81.

[0032] Following the positioning of the vertical steel beam 5 and the I-beam 1, the first limiting plate 80 in the first limiting structure 8 is then joined to one side of the vertical steel beam 5 and engaged with the slot 50. The first limiting plate 80 is then fixed using the third bolt 82. A reinforcing structure 7 is provided on the top of the horizontal steel beam 2 and attached to the steel beam 4, and on one side of the first limiting structure 8. The reinforcing structure 7 includes a connecting plate 70 and a first stiffening rib 71 located at the first end of the connecting plate 70. The second bolt hole 72 at one end of the connecting plate 70, the second bolt 73 symmetrically arranged at the second end of the connecting plate 70, and the reinforcing block 74 arranged at the angle between the connecting plate 70 and the first stiffening rib 71 are provided. The connecting plate 70 is attached to one side of the first limiting plate 80 and fixed by the second bolt 73. The first stiffening rib 71 abuts against one side of the vertical steel beam 5 and is connected and fixed to the vertical steel beam 5 by inserting a fixing bolt (not shown in the figure) into the bolt hole 72, thereby forming a stable abutment structure.

[0033] The second limiting structure 9 is located at one end of the I-beam 1 and on one side of the mounting component. The second limiting structure 9 includes a second limiting plate 90, fourth bolts 91 located at both ends of the second limiting plate 90, a second stiffening rib 92 located on the top surface of the second limiting plate 90, and a third buckle 93 located at one end of the second limiting plate 90 and near the fourth bolt 91.

[0034] After the first limiting structure 8 is fixed and sealed, the third buckle 93 on the second limiting plate 90 in the second limiting structure 9 is engaged with the slot 50. Then, the second limiting plate 90 is fixed by the fourth bolt 91. In order to strengthen the strength of the inclined steel beam 3, the second stiffening rib 92 is directly abutted against the inclined steel beam 3 and clamped and fixed while the second limiting plate 90 is installed, thus ensuring the strength of the inclined steel beam 3.

[0035] In summary, the slot 50 engages with the mounting component, connecting the I-beam 1 and the vertical steel beam 5. The first limiting structure 8 and the second limiting structure 9 block the slot 50, thereby enabling the vertical steel beam 5, the I-beam 1, and the attached steel beam 4 to be quickly positioned and installed. Consequently, the inclined steel beam 3 at one end of the vertical steel beam 5, the transverse steel beam 2 between the two I-beams 1, and the I-beam 1, the attached steel beam 4, and the vertical steel beam 5 combine and run in parallel to form a temporary attachment frame.

[0036] The other end of the I-beam 1 is provided with a positioning structure 6; the positioning structure 6 includes a positioning plate 60, a positioning hole 61 formed on the positioning plate 60, a positioning bolt 62 threadedly connected to the positioning hole 61, an elongated groove 64 formed on the positioning plate 60 and located on both sides of the positioning hole 61, a pivot seat 65 disposed inside the elongated groove 64, and a positioning rod 66 rotatably disposed on the pivot seat 65; a washer 63 is sleeved on the outer wall of the positioning bolt 62, and an abutment groove 67 formed on the washer 63 and abutting against the positioning rod 66.

[0037] To further ensure the stability of the entire attachment frame, the positioning bolt 62 in the positioning structure 6 at one end of the I-beam 1 is connected to the hole on the plane (not shown in the figure). As the positioning bolt 62 is gradually tightened, the positioning rod 66 on the pivot seat 65 abuts against the abutment groove 67 on the washer 63. This ensures that the positioning bolt 62 is always in the center of the hole in the positioning hole 61 and the hole on the plane (floor slab), making it less prone to shaking and ensuring accurate positioning.

[0038] Working principle:

[0039] Rapid positioning and installation are achieved through the groove 10 on the I-beam 1 and the slot 50 on the vertical steel beam 5. The mounting plate 102, the first bolt 103, and the first buckle 104 in the mounting components are used for fixation. Subsequently, the stability of the vertical steel beam 5 and the I-beam 1 is further ensured by the limiting plate and buckle in the first limiting structure 8 and the second limiting structure 9. The connecting plate 70 and the first stiffening rib 71 in the reinforcing structure 7 enhance the stability of the transverse steel beam 2. Finally, the positioning structure 6 at the end of the I-beam 1 ensures the accurate positioning and stability of the entire attachment frame through the positioning bolt 62 and the positioning rod 66, thus forming a temporary attachment frame that can be reused without the need for attachment to the main structure.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
