Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a hoisting frame for hoisting masonry materials. Background Art

[0002] The traditional way to transport masonry materials in high-rise buildings is to use small trolleys or construction hoists. For example, masonry materials such as wall filling bricks are loaded into small trolleys and then transported by construction elevators. For conventional construction hoists, since there is only an opening at the top, it is necessary to carry the masonry materials in and out, which is time-consuming and laborious.

[0003] Currently, there are block hoisting devices that can more conveniently realize the transfer of blocks. For example, the block hoisting cage in CN207671531U. After the hoisting cage sleeves the support of the block, a U-shaped pin is passed through the bottom of the support and the support is clamped, and then hoisting can be carried out. In order to ensure safety, such U-shaped pins usually use steel bars with a larger diameter. When inserting the pin, the construction worker squats down and pushes the pin towards the opposite jack. Since the pin is heavy and long, and the strength of the construction worker is limited, the construction worker cannot directly insert the pin straight into the opposite jack from one side of the hoisting cage, and the distal end of the pin will fall to the ground during the insertion process. The construction worker pushes the pin along the ground until the distal end of the pin reaches the opposite hoisting cage. Then, the construction worker needs to walk to the opposite side of the cage, squat down, then reach into the hanging basket with his hand, pick up the pin from the ground, and then hold the pin and pull it into the jack on this side. That is, the process of inserting the pin requires the construction worker to squat down, move his hands and exert force on both sides of the cage respectively, and the work efficiency needs to be improved.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above deficiencies in the prior art. Content of the Utility Model

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0035] like Figures 1 to 5 As shown, a hoisting frame for hoisting masonry materials comprises a cage body 1, a hoisting lug 3, a bottom lug 4, an insertion rod 6 and a guide slope;

[0036] The cage body 1 is a rectangular parallelepiped frame structure that penetrates from top to bottom; the cage body 1 includes two first facades and two second facades that are arranged oppositely; the width of the first facade is greater than the width of the second facade; the lifting ears 3 are fixed on both sides of the upper part of the second facade; the lifting ears 3 are inverted U-shaped, and the top ends of the lifting ears 3 extend beyond the cage body 1 to form hanging holes; the bottom ears 4 are fixed on both sides of the lower part of the second facade; the bottom ears 4 are U-shaped, and the lower ends of the bottom ears 4 extend beyond the cage body 1 to form insertion holes; the four insertion holes are arranged in a rectangular shape; the insertion rod 6 passes through the insertion holes on one side of the two second facades to form a support for the masonry material bracket; a bending portion is provided at one end of the insertion rod 6; the guide slope is obliquely arranged on the opposite side of the bottom ear 4, for guiding the insertion rod 6 to slide from the ground into the insertion hole;

[0037] When in use, the cage body 1 falls on the ground, and the guide slope falls on the ground accordingly and forms a guiding slope connecting the ground and the insertion hole. When the construction personnel push the insertion rod 6 into the insertion hole from the opposite side, the straight end of the insertion rod 6 slides along the ground to the guide slope and enters the insertion hole; the construction personnel only need to squat on one side of the cage body 1 and operate the insertion rod 6, and on the opposite side of the cage body 1, they only need to visually check the insertion status of the insertion rod 6 without having to lower the end again; the utility model can conveniently and quickly realize the fixing of the insertion rod 6 in the cage body 1, saving time, trouble and labor.

[0038] Further, such as Figures 1 to 3 As shown, the cage body 1 includes an upper frame, a lower frame, and a plurality of vertical rods fixed between the upper frame and the lower frame; in this embodiment, taking the wall filling bricks as an example, Figure 5As shown, its bracket includes a rectangular bracket plate 7, a footrest 8 fixed to the bottom surface of the long side of the bracket plate 7, and a reinforcement structure 9 fixed to the bottom surface of the bracket plate 7; correspondingly, for the cage body 1 of this embodiment, the interval between the first vertical rods of the first facade is greater than the interval between the second vertical rods of the second facade.

[0039] In a specific embodiment, as Figures 1 to 3 shown, there are 5 vertical rods forming the first facade and the second facade respectively, and the wall filling bricks on each bracket are tied and fixed together with the bracket by cable ties.

[0040] Further, the jacking hole is located between the vertical projections of the two hanging holes. The positions of the hanging holes are close to the four corners of the cage body 1. The position of the jacking hole avoids the position of the bracket footrest 8 and is set at a slightly inner position. In this way, after the insertion rod 6 is inserted, the two insertion rods 6 are between the two footrests 8; as Figures 1 to 3 shown, the lifting lugs 3 are welded and fixed to the two vertical rods closest to the edge, and the jacking holes are welded and fixed to the second and third vertical rods closest to the edge.

[0041] Further, as Figures 1 to 2 shown, the lifting lugs 3 are welded and fixed to the vertical rods on both sides of the second facade, and the overlapping length of the end of the lifting lugs 3 and the vertical rods is 250 mm or not less than 10 times the diameter of the lifting lugs.

[0042] Further, as Figures 1 to 3 shown, the bottom lugs 4 are welded and fixed to the vertical rods on both sides of the second facade, and the overlapping length of the end of the bottom lugs 4 and the vertical rods is 250 mm or not less than 10 times the diameter of the bottom lugs.

[0043] The cage body 1, the lifting lugs 3, and the bottom lugs 4 can be welded or bent from square tubes or steel bars; preferably, the cage body 1 is welded from steel bars with a diameter of 25 mm; the lifting lugs 3 and the bottom lugs 4 are bent from steel bars with a diameter of 25 mm; the insertion rod 6 is bent from one end of a steel bar with a diameter of 25 mm.

[0044] Preferably, as Figures 1 to 3 shown, a diagonal reinforcing rib 2 is fixed to one side of the first facade, and the diagonal reinforcing rib 2 can be made of a steel bar with the same specification as the vertical rod.

[0045] In an embodiment, as Figures 1 to 3 shown, the lifting frame for hoisting masonry materials further includes a guide plate 5 welded and fixed to the bottom lugs 4. The upper edge of the guide plate 5 does not exceed the lowest point of the jacking hole; the lower edge of the guide plate 5 does not exceed the bottom end surface of the bottom lugs 4; the upper surface of the guide plate 5 forms a guide slope; the guide plate 5 can be directly welded to the bottom lugs 4, or a support piece can be welded between the guide plate 5 and the bottom lugs 4 to form a strong support for the guide plate 5.

[0046] In another embodiment, asFigure 4 As shown, the hoisting rack for hoisting masonry materials further includes a guide plate 5. The upper part of the guide plate 5 is rotatably installed at a position near the upper edge of the opposite surface of the bottom ear 4, and the upper edge of the guide plate 5 never exceeds the lowest point of the jacking hole. The bottom ear 4 and the guide plate 5 can be connected by a hinge 10. One leaf of the hinge 10 is welded to the bottom ear 4, and then the upper edge of the guide plate 5 is welded to the other leaf of the hinge 10. Preferably, a limiting block 11 is fixed between the back surface of the guide plate 5 and the opposite surface of the second one, so that the angle between the two leaves of the hinge 10 is always at least 30°, preventing the hinge 10 from not opening after the cage lands. One side of the limiting block 11 is adhesively or welded to the bottom ear 4, and the other sides are not fixed to other components. Thus, when the hoisting rack is lifted, the guide plate 5 can naturally fall on the limiting block 11 to form an angle. During the process of the hoisting rack landing, as the guide plate 5 slides on the ground, this angle expands to form a guide slope. The limiting block 11 can be made of rubber sheets, springs, wooden blocks, pipe segments, etc. that are easily obtained at the construction site as long as they have a certain thickness or width, and the limiting block 11 is adhesively or welded according to the material selection. When the cage lands on the ground, the ground touches the guide plate 5, and the hinge 10 opens, so that the lower edge of the guide plate 5 can better adhere to the ground, facilitating the head end of the inserting rod 6 to slide from the ground to the guide slope.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are within the scope of protection of the pending claims of the present invention.
