Description

Technical Field

[0001] The present invention relates to the technical field related to building construction equipment, and in particular to a building hoisting device. Background Art

[0002] In the later stage of construction, the main task is to remove the formwork. Since most of the existing buildings are high-rise or super-high-rise, the disassembled formwork and related supporting accessories need to be transported out one by one. The most common way to transport these related building materials is to first open a small hole in the protective foot net, and then install the relevant unloading platform. At present, the fixed installation structure of the unloading platform is mostly to insert two connecting rods into the n-shaped embedded parts embedded in the floor slab for fixing. The unloading platform of this structure can actually only cope with the axial tension of the connecting rod, and since the unloading platform is extended out of the protective net, each connecting rod is actually supported by two n-shaped embedded parts. First of all, the n-shaped embedded parts must bear the unloading The upward pulling force of the platform is the main reason for the poor bearing capacity of all existing unloading platforms. It is not uncommon for unloading platforms to overturn and cause casualties during construction and application. In view of this, some of our project departments require that a diagonal brace steel pipe must be installed at the bottom of the extended part of the unloading platform to the next floor. We have also tested this method through ballast, which can at least increase the load of the existing platform by 50%. However, the operation of installing the diagonal brace steel pipe is very dangerous. The main reason is that the unloading platform is the protrusion of the entire main building, and the workers have to hang down from the bottom of this protrusion to set up the diagonal brace, which is difficult to construct and has low work efficiency.

[0003] Therefore, how to improve the carrying capacity of the unloading platform is the key to improving the efficiency of lifting and transportation. Summary of the invention

[0019] A positioning seat 10 is provided on each driving box 7, and the two positioning seats 10 are connected and fixed as a whole by a driving shaft 11. A second slide rail 12 is vertically extended downward from the lower bottom surface of the positioning seat 10, and the lower bottom surface of the second slide rail 12 is welded and fixed to the second driving slider 13 as a whole. A positioning shaft rod 14 that can slide with it is provided in the middle of the second driving slider 13, and one end of the positioning shaft rod 14 is vertically welded and fixed to the inner wall of the driving box 7. A return spring 26 is sleeved on the positioning shaft rod 14, and the two ends of the return spring 26 are respectively pressed between the inner wall of the driving box 7 and the second driving slider 13. A second guide slide groove 15 that can slide with the second slide rail 12 is provided on the driving box 7. A driving plate 16 that can slide against the lower bottom surface of the driving box 7 is welded to the bottom of the second driving slider 13, and a plurality of positioning sliders 17 arranged equidistantly are welded on the driving plate 16;

[0020] The driving box 7 is provided with several through holes corresponding to the positioning slider 17, each of which is provided with an ear seat 18 that can slide with the gap therein, and a support rod 19 that can be rotatably connected and matched therewith is installed above the ear seat 18, and both sides below the ear seat 18 respectively extend vertically outward to form a stopper 20 to prevent the ear seat 18 from going out of the through hole, and the cross section of the positioning slider 17 is a right-angled trapezoidal structure; under the drive of the second driving slider 13, when the lower end of the ear seat 18 passes through the hypotenuse of the positioning slider 17 and rises to the upper top edge of the positioning slider 17, the ear seat 18 rises to the highest state;

[0021] Driving connecting rods 21 which can be rotatably connected and matched therewith are respectively installed on the two side surfaces of the unloading platform 8. The driving connecting rods 21 are rotatably connected and matched with each supporting rod 19 in the same row through a hinge shaft.

[0022] The upper end of the support rod 19 is provided with a screw rod 22 which is spirally matched therewith. A top plate 23 is welded to the upper end of the screw rod 22. Bosses 24 are respectively welded and fixed on both sides of the lower bottom surface of the top plate 23.

[0024] Lifting ears are welded on both sides of the top of the hanging bucket 9.

[0025] The working principle and implementation process of the technical solution in this specific implementation method are further explained below in conjunction with the figure:

[0026] During operation, firstly, the height of the floor should be roughly measured, and the screw rod 22 should be adjusted to the corresponding height (but the rising height of the ear seat 18 and the support rod 19 should be left), and then the drive motor 2 should be started to drive the unloading platform 8 to move horizontally in the direction of the drive shaft 11 through the screw rod 3 and the first drive slider 4. During the horizontal movement, the unloading platform 8 drives each support rod 19 to gradually become perpendicular to the drive box 7 with the ear seat 18 as the center through the driving connecting rod 21. When the unloading platform 8 gradually runs to the top, the unloading platform 8 starts to contact with the drive shaft 11 and moves through the drive shaft 11 and the positioning seat 10. The second driving slider 13 is driven to slide along the axial direction of the positioning shaft 14 and compress the reset spring 26. During the sliding process, the second driving slider 13 drives each positioning slider 17 through the driving plate 16. The lower end of the ear seat 18 is a spherical structure. The ear seat 18 is lifted by the bevel of the positioning slider 17. The ear seat 18 and the support rod 19 gradually move upward until the top plate 23 directly contacts the ceiling vertically to achieve the installation of the entire lifting equipment. Of course, it is necessary to pre-tighten the screw 22 at the end, and use a hammer to hit the boss 24 to make the top plate 23 tightly against the ceiling, so as to achieve the purpose of vertical fixation.

[0027] When storing, it is only necessary to hit the boss 24 to loosen the contact between the top plate 23 and the ceiling.
