[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] Refer to the accompanying specification Figures 1-5 , the present invention provides an auxiliary device for opening holes in a floor slab, including a cross beam 1. An electric hoist 2 for guiding and transporting the floor slab is connected to the bottom end of the cross beam 1. Columns 3 are arranged on both sides of the electric hoist 2. Connecting steel plates I 4 are fixedly arranged at the top ends of the two columns 3, and the two connecting steel plates I 4 are detachably and fixedly connected to the cross beam 1. Connecting steel plates II 5 are fixedly arranged at the bottom ends of the two columns 3, and detachable steel base plates 6 are fixedly arranged at the bottom ends of the two connecting steel plates II 5. Carriage wheels 7 are fixedly arranged at the four corners of the bottom ends of the two steel base plates 6;

[0026] Rotating rods 8 penetrate through the front ends of the two columns 3, and detachable limit plates 9 are sleeved on the front and rear ends of the rotating rods 8. Rubber strips 10 are fixedly arranged on one side of each limit plate 9 close to the electric hoist 2. A plurality of grooves 11 are processed on the outer wall surface of the rubber strip 10 to increase the friction force on the surface of the rubber strip 10;

[0027] The crossbeam 1 and the two columns 3 are both H-shaped steel beams. The H-shaped steel beam is light in weight and can effectively reduce the total weight of the entire device. Secondly, the H-shaped steel beam has high strength and a large section modulus. Under the premise of meeting the same load-bearing capacity, the H-shaped steel beam can save metal content compared with traditional materials, thereby reducing manufacturing costs.

[0028] Next, a driving assembly 12 for driving the rotating rod 8 to rotate is fixedly provided at the rear end of each of the two columns 3. Each driving assembly 12 includes a motor 1201. The motor 1201 is provided below the limit plate 9. The output shaft of the motor 1201 is connected to the rotating rod 8 through a bevel gear set 1202. A support plate 1203 is fixed to the bottom end of each of the two motors 1201. The support plate 1203 is fixed to the rear end of the column 3 to improve the stability of the motor 1201 when in use.

[0029] Furthermore, in order to facilitate the staff to operate the motor 1201 and the electric hoist 2, a control switch 13 is fixed on the far side of the two columns 3, and the control switch 13 is connected to the electric hoist 2 and the motor 1201 through wires;

[0030] In order to improve the stability of the steel base plate 6 when it is stationary, a threaded rod 14 is passed through the top of the two steel base plates 6. The two threaded rods 14 are distributed on the front and rear sides of the column 3, and the threaded rods 14 are threadedly connected to the steel base plate 6. A foot pad 15 is fixed to the bottom end of the threaded rod 14. Tighten the threaded rod 14 so that the foot pad 15 is against the ground, thereby improving the stability of the steel base plate 6.

[0031] Before drilling holes in the floor slab, the staff first implants multiple anchor bolts on the floor slab according to calculations, and then connects the anchor bolts to an electric hoist 2 (or manual hoist) on the beam 1 before drilling holes. After the drilling is completed, the cut floor slab is first lifted vertically away from the floor surface using the electric hoist 2, and then horizontally moved to the stacking location through multiple carriage wheels 7 at the bottom of the steel base plate 6. The floor slab is hoisted by the electric hoist 2, which can effectively solve the safety risks caused by the falling of debris during the drilling process, save manpower in handling, and improve the efficiency of transportation.

[0032] In addition, before transferring the floor slab, the staff can use the control switch 13 to control the operation of the two motors 1201, and use the motor 1201 and the bevel gear set 1202 to drive the rotating rod 8 to rotate, so that the two limit plates 9 on the two columns 3 move toward the floor slab on the electric hoist 2 and press the floor slab, so as to prevent the floor slab from shaking during transportation, thereby improving the safety of the staff during operation.

[0033] Furthermore, by arranging threaded rods 14 on the steel bottom plate 6 and twisting the threaded rods 14 so that the foot pads 15 at the bottom thereof come into contact with the ground, the stability of the steel bottom plate 6 can be improved, thereby improving the stability of the electric hoist 2 .

[0034] Embodiment 2

[0035] Different from Embodiment 1, referring to the appended drawings of the specification Figure 5 , two electric hoists 2 are arranged on the cross beam 1 to improve the stability when guiding and transporting the floor slab. Bolts 16 penetrate through both of the limiting plates 9, and the bolts 16 are threadedly connected to the limiting plates 9. One end of each bolt 16 contacts the outer wall of the column 3.

[0036] The staff directly loosens the bolts 16 on the limiting plates 9, then manually moves the limiting plates 9 to press against the floor slab generated by the opening, and then tightens the bolts 16 to fix the limiting plates 9. After that, the column 3 can be pushed to transport the floor slab generated by the opening.

[0037] Finally: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
