Technical Field

[0001] This utility model relates to a lifting hopper, and more particularly to a special lifting hopper suitable for lifting miscellaneous building materials such as pipes, steel bars and profiles of varying lengths in construction, belonging to the field of lifting and hoisting technology. Background Technology

[0002] In construction projects such as bridges, docks, tunnels, and buildings, there is a need to lift large quantities of pipes, plates, and various types of timber, as well as to use slings to lift smaller, irregularly sized building materials. Existing slings for these smaller materials generally suffer from the following problems:

[0003] It cannot simultaneously lift scattered building materials of varying lengths, such as long steel bars, long pipes, and long profiles that exceed the length of the hoisting box, as well as short pipes, short steel bars, and short profiles that are shorter than the length of the hoisting box. In addition, the existing hoisting box door structure is mostly a single-sided swing type, which occupies a lot of space when opened and lacks anti-accidental opening devices, posing a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a special hoisting box for small building materials with simple structure that can safely hoist profiles and steel bars of different lengths at the same time.

[0005] This utility model is achieved through the following technical solution:

[0006] A special hoisting box for miscellaneous building materials includes a cuboid frame welded from perpendicularly intersecting square steel pipes. Except for the open top of the cuboid frame, the other inner sides are welded with hoisting box sealing plates. The vertical rods at the four corners of the cuboid frame extend downward from the bottom of the cuboid frame and support the ground. Rectangular recesses are recessed in the upper middle part of the side frames on both longitudinal sides of the cuboid frame, and opening and closing flaps are located in the rectangular recesses. The opening and closing flaps include a rectangular flip frame and a flip side plate welded to the inner side of the rectangular flip frame. The lower ends of the rectangular flip frame are hinged to the two ends of the middle rod on the lower side of the rectangular recess by hinges. The upper ends of the rectangular recess are locked by upper opening and closing locking devices for the upward-flipped opening and closing flaps. The lower ends of the side frames are locked by lower opening and closing locking devices for the opening and closing flaps that have been flipped downward by 180°.

[0007] The objective of this utility model can also be further achieved through the following technical measures.

[0008] Furthermore, the upper opening and closing locking device includes a spring pin, a spring pin mounting base, and a locking base. The spring pin body is fixed on the spring pin mounting base, and the spring pin mounting base is fixed on the upper horizontal bar ends outside the upper sides of the rectangular notch. The locking base is fixed on the top corner of the rectangular flip frame, and the locking holes of the locking base correspond to the pin positions of the spring pins on the upper horizontal bar ends. The lower opening and closing locking device has its spring pin body fixed on the spring pin mounting base, and the spring pin mounting base is fixed on both ends of the lower horizontal bar of the cuboid frame. The locking holes are located on the top of the vertical side of the rectangular flip frame. When the opening and closing flip plate is locked upwards, the pins of the spring pins on the upper horizontal bar ends of the rectangular notch extend into the upper locking holes of the corresponding locking bases on the top corners of the rectangular flip frame, locking the opening and closing flip plate in the upward reset state. When the opening and closing flip plate is locked downwards, the pins of the spring pins on the lower horizontal bar extend into the lower locking holes on the top of the vertical side of the rectangular flip frame, locking the opening and closing flip plate in the downward state.

[0009] Furthermore, lifting angle steels with lifting holes at the top are welded to the upper part of the vertical rods of the cuboid frame.

[0010] Furthermore, the ratio of the length A1 of the rectangular notch to the length A2 inside the cuboid frame is: A1 / A2 = 0.80~0.86; the ratio of the height B1 of the rectangular notch to the height B2 inside the cuboid frame is: B1 / B2 = 0.48~0.52.

[0011] This invention features a simple structure, high strength, and long service life. After the opening and closing flap folds down and locks to expose the rectangular recess, short pipes, short steel bars, and short profiles with lengths shorter than the internal length of this invention can be placed inside the box at the bottom of the rectangular recess. Several layers of longer pipes, steel bars, and profiles with lengths greater than the internal length of this invention can be stacked horizontally inside the rectangular recess, solving the problem that existing hoisting boxes cannot simultaneously lift building materials of varying lengths. After the opening and closing flap folds up and locks to close the rectangular recess, the entire box can be used to lift and transport small building materials, making it convenient and flexible to use. The spring pin locking device provides reliable locking, and the opening and closing flap does not occupy external space during use, significantly improving the lifting safety of this invention.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-3 As shown, this utility model includes a cuboid frame 1 welded from perpendicularly intersecting square steel pipes. Except for the open top of the cuboid frame 1, the other inner surfaces are each welded with a hanging box sealing plate 2. Vertical rods 11 at the four corners of the cuboid frame 1 extend downwards from the bottom of the cuboid frame 1 and support it on the ground, improving the support stability of this utility model. In this embodiment, galvanized square steel pipes with a wall thickness of 5mm are used, which are high in strength, corrosion-resistant, and have a long service life.

[0020] like Figure 2 As shown, rectangular recesses 13 are recessed into the upper middle part of the side frames 12 on both longitudinal sides of the cuboid frame 1. The length of the rectangular recesses 13 is greater than the width of the special hoisting box, and they are used to hold pipes, steel bars, and profiles with a length greater than the length of the special hoisting box. The opening and closing flap 3 is located in the rectangular recesses 13. The opening and closing flap 3 includes a rectangular flip frame 31 and a flip side plate 32 welded to the inner side of the rectangular flip frame. Both the hoisting box sealing plate 2 and the flip side plate 32 are made of steel plate with a thickness of 5mm. The lower ends of the rectangular flip frame 31 are respectively hinged to the two ends of the middle rod 131 on the lower side of the rectangular recess 13 by hinges 4. The upper ends of the rectangular recess 13 are locked by upper opening and closing locking devices 5 to lock the upward-flipping opening and closing flap 3, and the lower ends of the side frames 12 are locked by lower opening and closing locking devices 6 to lock the downward-flipping opening and closing flap 2 that has been flipped 180°.

[0021] like Figure 5 As shown, the upper opening and closing locking device 5 includes a spring pin 51, a spring pin mounting base 52, and a locking base 53. The spring pin body 511 is fixed on the spring pin mounting base 52. The spring pin mounting base 52 is fixed on the ends of the upper horizontal bar 14 outside the upper sides of the rectangular recess 13. The locking base 53 is fixed on the top corner of the rectangular flip frame 31. The upper locking hole 531 of the locking base 53 corresponds to the position of the pin body 512 of the spring pin 51 on the end of the upper horizontal bar 14.

[0022] like Figure 4As shown, the spring pin body 511 of the lower opening and closing locking device 6 is fixed on the spring pin mounting base 52, and the spring pin mounting base 52 is fixed on the lower crossbar 121 of the cuboid frame 11. The lower locking hole 311 is set on the top of the vertical side of the rectangular flip frame 31.

[0023] When the opening / closing flap 3 is locked upwards, the pins 512 of the spring pins 51 on the ends of the upper crossbars 14 at both ends of the rectangular notch 13 extend into the upper locking holes 531 of the corresponding locking seats 53 on the top corners of the rectangular flip frame 31, locking the opening / closing flap 3 in the upward reset state. When the opening / closing flap 3 is locked downwards, the pins 512 of the spring pins 51 on the lower crossbar 121 extend into the lower locking holes 311 on the top of the vertical side of the rectangular flip frame 31, locking the opening / closing flap 3 in the downward state.

[0024] like Figure 1 and Figure 2 As shown, lifting angle steel 7 with lifting holes 71 at the top is welded to the upper part of the vertical rod 11 of the cuboid frame 1.

[0025] like Figure 2 As shown, in this embodiment, the ratio of the rectangular notch length A1 to the inner length A2 of the cuboid frame is A1 / A2 = 0.83, and the ratio of the rectangular notch height B1 to the inner height B2 of the cuboid frame is B1 / B2 = 0.50. This allows the rectangular notch 13 to be used to support a large number of long pipes, long steel bars, and long profiles.

[0026] When using this invention to simultaneously hoist long building materials and miscellaneous short building materials, first release the locking pin 512 of the upper opening and closing locking device 5, then pull the pin 512 outwards so that the pin 512 disengages from the upper locking hole 531 of the locking seat 53, and the opening and closing flap 3 is unlocked. The opening and closing flap 3 can then be flipped downwards 180°. Next, release the locking pin 512 of the lower opening and closing locking device 6, and then insert the pin 512 into the lower locking hole 311 on the top vertical side of the corresponding rectangular flip frame 31, so that the opening and closing flap 3 is locked in the flipped-down state. Miscellaneous building materials such as short pipes, short steel bars, and short profiles of varying lengths can then be placed in the lower part of this invention. Then, long steel bars and long profiles with a length greater than the inner length of this invention can be evenly placed horizontally in the rectangular recess 13 at the upper part of this invention. Since the opening and closing flap 3 is fixed on the cuboid frame 1 when opening and closing, it does not occupy the external space of the box, making the hoisting very safe and significantly improving the overall hoisting capability of this utility model.
