Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a lifting frame with adjustable lifting points. Background Technology

[0002] In modern urbanization, especially subway construction, when it comes to relatively prosperous areas and urban areas, it is necessary to ensure the site conditions required for normal construction while also ensuring smooth traffic. In such cases, the foundation pit will usually be constructed using the partial excavation method.

[0003] In construction, lifting equipment is indispensable for everything from steel support erection and dismantling to the hoisting of rebar and formwork. Currently, the most widely used and economical are various crawler cranes and truck cranes. However, these conventional cranes can only lift vertically when there are no obstructions, leaving them helpless when there are cover plates. During earthwork excavation, hoisting under cover plates can only be done with excavators, while rebar and other materials must be handled manually. Excavator hoisting is risky, while manual handling is inefficient. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing lifting equipment cannot perform vertical lifting when obstructed. To address this problem, a lifting frame with adjustable lifting points is proposed, comprising a horizontal rod, a sleeve rod, a telescopic rod, and a vertical connecting rod. The telescopic rod is slidably connected within the sleeve rod and fixed by a pin. The horizontal rod is located above the sleeve rod and is parallel to it. Both ends of the vertical connecting rod are connected to the horizontal rod and the sleeve rod, respectively. The combined length of the sleeve rod and the telescopic rod is greater than the length of the horizontal rod. The ends of both the horizontal rod and the telescopic rod furthest from the vertical connecting rod are provided with shackles for connecting lifting wire ropes.

[0005] The technical solution of this embodiment, the technical solution of this utility model, by using a structure in which the horizontal height of the sleeve rod is lower than that of the cover plate, the sleeve rod can extend under the cover plate to lift and move objects in the obstructed area; through the structure of the sleeve rod and the telescopic rod slidingly connected, the length of the telescopic rod extending out of the sleeve rod is adjustable, and the lifting point of the object to be lifted is adjustable, thus realizing the lifting and movement of objects under cover plates of different spans without the need for manpower or other machinery, improving work efficiency, saving manpower and machinery costs, and also greatly improving the safety of such lifting operations.

[0006] In a preferred embodiment of the present invention, both the telescopic rod and the sleeve rod are provided with multiple openings for passing through bolts. The openings on the telescopic rod and the sleeve rod facilitate fixing by bolts. Furthermore, by having the openings on the telescopic rod correspond to different openings on the sleeve rod, the length can be adjusted, thereby adjusting the position of the lifting point.

[0007] In a preferred embodiment of the present invention, the vertical connecting rod is perpendicular to the horizontal rod and the sleeve rod, and a tie plate is provided at the angle between the vertical connecting rod and the horizontal rod and the sleeve rod. The tie plate is used to strengthen the fixation, improve the stability of the hanger, and reduce the probability of the horizontal rod and the sleeve rod breaking off from the connection point with the vertical connecting rod.

[0008] In a preferred embodiment of the present invention, the tie plate is in the shape of an isosceles right triangle. One right-angled side of the tie plate is connected to the vertical connecting rod, and the other right-angled side is connected to the horizontal rod or sleeve rod. The tie plate is fixed by welding, which increases the area of ​​the connection and strengthens the stability between the horizontal rod / sleeve rod and the vertical connecting rod.

[0009] In a preferred embodiment of the present invention, the length of the vertical connecting rod is greater than the thickness of the cover plate during partial half-cover construction. This ensures that the sleeve rod and telescopic rod are located below the cover plate, enabling the hoisting of objects below the area covered by the cover plate.

[0010] In a preferred embodiment of the present invention, the horizontal height of the sleeve rod is lower than that of the cover plate, and the outer end of the telescopic rod is located below the cover plate. Since the sleeve rod is lower than the cover plate, the telescopic rod connected to it is also located below the cover plate. This allows for the hoisting and movement of objects obscured below the cover plate.

[0011] The advantages of this utility model compared with the prior art are:

[0012] The technical solution of this utility model, through the structure that the horizontal height of the sleeve rod is lower than that of the cover plate, allows the sleeve rod to extend under the cover plate to lift and move objects in the obstructed area; through the structure that the sleeve rod and the telescopic rod are slidably connected, the length of the telescopic rod extending out of the sleeve rod is adjustable, and the lifting point of the object to be lifted is adjustable. Therefore, it is possible to lift and move objects under cover plates of different spans without the need for manpower or other machinery, thereby improving work efficiency, saving manpower and machinery costs, and greatly improving the safety of such lifting operations.

[0016] The following will refer to the appendix in the embodiments of this utility model. Figure 1-2 The technical solutions in the embodiments of this utility model will be described in detail below. Embodiment 1

[0017] As shown in Figure 1-2 Figure, the utility model is a hanging bracket with adjustable hanging points, including a horizontal rod 2, a sleeve rod 3, a telescopic rod 4 and a vertical connecting rod 5.

[0018] The telescopic rod 4 is slidably connected in the sleeve rod 3 and fixed by a bolt pin 7. A plurality of openings for passing the bolt pin 7 are provided on both the telescopic rod 4 and the sleeve rod 3. The telescopic rod 4 slides in the sleeve rod 3. When the length of the telescopic rod 4 extending out of the sleeve rod 3 reaches the required length range, through fine adjustment, the openings on the telescopic rod 4 are made to correspond to the openings on the sleeve rod 3. At this time, the telescopic rod 4 and the sleeve rod 3 can be fixed by the bolt pin 7.

[0019] The horizontal rod 2 is parallel to the sleeve rod 3 and is located above the sleeve rod 3. The sleeve rod 3 and the telescopic rod 4 are connected to form an assembly. The length of this assembly is greater than the length of the horizontal rod 2. Therefore, in the case of local semi-covered construction, even if the horizontal rod 2 is in an uncovered area, the assembly can still extend under the cover plate 8 in the covered area to hoist the object to be hoisted, improving efficiency. The two ends of the vertical connecting rod 5 are respectively fixedly connected to the horizontal rod 2 and the sleeve rod 3. The specific connection method can also be fixed by the bolt pin 7.

[0020] It should be noted that the length of the vertical connecting rod 5 is greater than the thickness of the cover plate 8 during local semi-covered construction operations. Therefore, it can ensure that the horizontal height of the sleeve rod 3 is always lower than the cover plate 8. The telescopic rod 4 can always be kept below the cover plate 8 by adjusting the length extending out of the sleeve rod 3, which is convenient for hoisting and moving the object to be hoisted in the semi-covered area, saving manpower and improving efficiency.

[0021] The vertical connecting rod 5 is perpendicular to the horizontal rod 2 and the sleeve rod 3, and the overall shape is an "L" - shaped frame. Among them, the assembly formed by the sleeve rod 3 and the telescopic rod 4 serves as the lower bottom edge of the "L", and its length is greater than the horizontal rod 2 serving as the upper bottom edge. The included angles between the vertical connecting rod 5 and the horizontal rod 2 and the sleeve rod 3 are right angles. At the right angles, a reinforcing gusset plate 6 is fixed by welding, and a reinforcing gusset plate 6 is welded and installed at both the upper and lower right angles.

[0022] The gusset plate 6 is in the shape of an isosceles right triangle. One right - angled side of the gusset plate 6 is fitted and connected to the vertical connecting rod 5, and the other right - angled side is fitted and connected to the horizontal rod 2 or the sleeve rod 3.

[0023] An installation hole is provided at the end of the horizontal rod 2 far from the vertical connecting rod for connecting with a shackle 1, and this shackle 1 is used to connect the steel wire rope of the hoisting equipment; an installation hole is also provided at the end of the telescopic rod 4 far from the vertical connecting rod, and a shackle 1 is connected. This shackle 1 is connected to the object to be hoisted through a steel wire rope.

[0024] It should be noted that there may be some inaccuracies in the understanding and translation of the geometric shape description in this text. The "匚" - shaped frame description in the original text may need to be further confirmed according to the actual situation. If it is a "U" - shaped frame, the translation should be adjusted accordingly. Also, for the numbers and symbols like , they are usually specific identifiers in a patent context and are directly retained without translation.In use, the horizontal bar 2 is located in the uncovered area, and the telescopic bar 4 is located below the cover plate 8 in the covered area. The wire rope of the hoisting equipment is connected to the shackle on the horizontal bar 2. The object to be hoisted is connected to the shackle 1 on the telescopic bar 4 through the wire rope. At this time, the hoisting equipment can be started to hoist and move the object to be hoisted in the covered area without the need for manual movement, saving manpower and greatly improving efficiency.

[0025] Meanwhile, the length of the telescopic rod 4 extending out of the sleeve rod 3 can be adjusted to suit cover plates 8 of different spans, so as to lift the objects to be lifted below them. It should be noted that during the lifting process, because the length of the telescopic rod 4 is adjusted, one end of the telescopic rod 4 with the shackle 1 will be lower than the other end. At this time, the entire "U"-shaped frame will tilt at a certain angle, but this tilt will not affect the lifting and moving of the objects to be lifted.

[0026] The method of using a hanger with adjustable suspension points in this embodiment is as follows:

[0027] First, connect the wire rope of the hoisting equipment to the shackle 1 on the horizontal bar 2. Then, release the bolts 7 that secure the telescopic rod 4 and the sleeve rod 3. Adjust the length of the telescopic rod 4 extending beyond the sleeve rod 3 until the required length is reached. Then, reconnect the telescopic rod 4 and the sleeve rod 3 using the bolts 7. At this point, the hoisting frame is adjusted and hoisting work can begin. Start the hoisting equipment, lift the hoisting frame, and slowly lower it to the unobstructed area while simultaneously moving the telescopic rod 4 under the cover plate 8. Next, connect the wire rope of the object to be hoisted to the shackle 1 on the telescopic rod 4. Finally, use the hoisting equipment to lift the object under the cover plate 8 and move it along the edge of the cover plate 8 or out of the covered area. This process requires no manual labor or other machinery, saving manpower and machinery costs, greatly improving efficiency, and reducing safety hazards.

[0028] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
