Description

Technical Field

[0001] This utility model relates to the field of pallet auxiliary lifting frame technology, and in particular to a concrete block lifting frame. Background Technology

[0002] Precast concrete blocks are an important building material. Construction sites typically require large quantities of these blocks, which are usually lifted using cranes. Specifically, the blocks are stacked on pallets (and secured with straps to prevent them from falling during lifting). Lifting slings are then used to lift the pallets and blocks, allowing for the lifting of a large number of blocks at once and significantly improving transport efficiency. In practice, to facilitate the connection of the lifting slings, load-bearing strips are often attached to the bottom of the pallet. These strips, usually two in number, extend beyond the pallet at both ends for the lifting slings to be fitted onto. The slings then wrap around the top of the concrete blocks and connect to the crane's boom. While this improves transport efficiency, the ends of the load-bearing strips also extend beyond the stacked blocks (otherwise, the lifting slings cannot properly connect to the strips), potentially affecting construction workers' work and causing unnecessary danger (such as accidental collisions leading to injury). Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a concrete block hoisting frame, which solves the problem that the ends of the load-bearing bars located outside the pallet may affect the construction workers' work.

[0004] According to an embodiment of this utility model, a concrete block hoisting frame includes a pallet with a top surface and a bottom surface. The top surface is for stacking concrete blocks, and the bottom surface is fixedly connected to a pair of load-bearing strips, the ends of which are located within the pallet's coverage area. The two load-bearing strips are parallel and have a first through hole along their axial direction. The frame also includes connecting strips that pass through the two first through holes, with both ends of each connecting strip located outside the pallet. A hook is fixedly connected to the same end of each connecting strip. Furthermore, it includes four hoisting straps connected to both ends of the two connecting strips, each strap having a collar to engage with the ends of the connecting strips. In this design, the connecting strips replace the load-bearing strips for connecting the hoisting straps, ensuring the normal operation of the hoisting process. After completion, the connecting strips can be smoothly pulled out with the assistance of the hoisting straps without affecting the construction workers' work. Simultaneously, the load-bearing strips are not exposed, thus solving the problem in the prior art where the ends of the load-bearing strips located outside the pallet could affect the construction workers' work.

[0005] Furthermore, both the first perforation and the connecting strip have square cross-sections, and the length and width of the connecting strip cross-section are smaller than the length and width of the first perforation cross-section.

[0006] Furthermore, a crossbar is fixedly connected between the two ends of the two load-bearing bars, and a second through hole is provided on each of the two crossbars, which communicates with the first through hole so that the connecting bar can pass through.

[0007] Furthermore, the cross-section of the second perforation is a square with the same dimensions as the first perforation.

[0008] Furthermore, the hook has a free end that extends upward toward the tray.

[0009] Furthermore, the hook has a free end extending downwards toward the tray.

[0010] Furthermore, the free end of the hook is located between the bottom surface of the load-bearing strip and the bottom surface of the connecting strip.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The end of the load-bearing strip is placed within the pallet's coverage area, and a connecting strip passes through the first perforation. The connecting strip replaces the load-bearing strip for connection with the lifting strap, ensuring normal lifting operations. After lifting, the connecting strip can be easily pulled out with the lifting strap, and then the next round of lifting can begin. The stacking of the lifted concrete blocks will not be adversely affected by the load-bearing strip or the connecting strip, solving the problem in the prior art where the end of the load-bearing strip is located outside the pallet, which may affect the construction workers' operations.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] In an exemplary implementation, such as Figure 1-6 As shown, this embodiment provides a concrete block hoisting frame, which includes a pallet 1. The pallet 1 has a top surface and a bottom surface, wherein the top surface is for stacking concrete blocks. After stacking into a concrete block pile 10, it can be fixed with straps similar to the prior art. Furthermore, a pair of load-bearing strips 2 are fixedly connected to the bottom surface of the pallet 1, and the ends of the two load-bearing strips 2 are located within the coverage area of ​​the pallet 1, thus avoiding the load-bearing strips 2 from affecting the construction. The two load-bearing strips 2 are parallel and have a first through hole 3 along their axial direction. The hoisting frame also includes connecting strips 4 that pass through the two through holes 3 respectively, and both ends of the two connecting strips 4 can be located outside the pallet 1. A hook 5 is fixedly connected to the same end of the two connecting strips 4 respectively. The hoisting frame also includes four hoisting straps 6 connected to both ends of the two connecting strips 4. The hoisting straps 6 are equipped with collars 7 to fit around the ends of the connecting strips 4. The structure of the hoisting straps 6 is similar to that in the prior art. The collars 7 and the rest of the straps are wide-bodied strip structures, which can increase the contact surface and thus improve stability. At the same time, after hoisting is completed, pulling the collars 7 of the hoisting straps 6 outward can also fit around the hooks 5, making it easy to pull the connecting strips 4 outward. In this way, the outer edge of the concrete block pile 10 has neither the load-bearing strips 2 nor the connecting strips 4, which will not have an adverse impact on construction. This solves the problem in the prior art where the end of the load-bearing strip 2 is located outside the pallet 1, which may affect the construction workers' work.

[0024] In a further embodiment, a horizontal bar 8 is fixedly connected between the two ends of the two load-bearing bars 2. The horizontal bar 8 is also fixed to the bottom surface of the tray 1 and is located within the coverage area of ​​the tray 1, which can increase the stability of the overall structure. At the same time, a second through hole 9 communicating with the first through hole 3 is provided on the horizontal bar 8, and both the first through hole 3 and the second through hole 9 can be squares of the same size (i.e., the length and width of the cross section are the same). The connecting bar 4 is also square, but its size is smaller than that of the first through hole 3 and the second through hole 9, so that the connecting bar 4 can be smoothly inserted and withdrawn.

[0025] In one embodiment, the hook 5 can be a free end that extends upwards, that is, the hook 5 has a free end that extends upwards towards the pallet 1. In this way, the collar 7 of the lifting strap 6 can be pulled outwards first, and then the connecting strip 4 can be pulled out by putting it on the hook 5 and pulling it outwards.

[0026] In another embodiment, the free end of the hook 5 can also extend downward, that is, the hook 5 has a free end extending downward toward the pallet 1. During the process of the lifting sling 6 pulling outward, the collar 7 can be caught with the hook 5 to pull out the connecting strip 4 more smoothly. More specifically, the free end of the hook 5 is located between the bottom surface of the load-bearing strip 2 and the bottom surface of the connecting strip 4 to avoid the hook 5 from contacting the ground during the process and causing collision damage.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
