[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] See attached Figure 1-4 A detachable and movable simple lifting and hoisting device comprises two parallel I-beam bottom beams 1, the I-beam bottom beam 1 is arranged horizontally, a vertical supporting I-beam 2 is vertically and detachably connected to the middle of the top surface of the I-beam bottom beam 1, and the top ends of the two vertical supporting I-beams 2 are detachably connected through a transverse supporting I-beam 3; movable pulleys 4 are fixedly installed at both ends of the bottom surface of the I-beam bottom beam 1; a U-shaped ring 5 is fixedly connected to the middle of the bottom surface of the transverse supporting I-beam 3, and a lifting mechanism 6 is connected to the U-shaped ring 5.

[0021] The two I-beam bottom beams 1 are aligned at both ends, the vertical supporting I-beam 2 is perpendicular to the I-beam bottom beam 1, and the transverse supporting I-beam 3 is perpendicular to both the vertical supporting I-beam 2 and the I-beam bottom beam 1; the I-beam bottom beam 1 and the vertical supporting I-beam 2, and the vertical supporting I-beam 2 and the transverse supporting I-beam 3 are connected by I-beam connectors 10 and anchor bolts 11, and the models of the anchor bolts are consistent.

[0022] The I-beam connector 10 is a steel plate bent into different shapes and has a number of through holes 12 at both ends. The shape of the I-beam connector 10 corresponds to the shape required by the connection position. For example, at the connection between the I-beam bottom beam 1 and the vertical support I-beam 2, the I-beam connector 10 is L-shaped and can be attached to the I-beam bottom beam 1 and the vertical support I-beam 2 at the same time. The I-beam bottom beam 1 and the vertical support I-beam 2 have threaded holes (not shown in the figure) at positions corresponding to the through holes 12. The threaded holes are compatible with the anchor bolts 11, and then the anchor bolts 11 are used to pass through the through holes 12 and are threadedly connected to the threaded holes. In this way, the I-beam bottom beam 1 and the vertical support I-beam 2 can be fixedly connected. In the same way, the vertical support I-beam 2 and the horizontal support I-beam 3 can also be fixedly connected. This technology belongs to the existing conventional connection method and will not be repeated here.

[0023] The I-beam bottom beam 1, the vertical supporting I-beam 2 and the transverse supporting I-beam 3 will form a door-shaped frame. A U-shaped ring 5 is fixedly connected to the middle of the bottom surface of the transverse supporting I-beam 3. A lifting mechanism 6 is connected to the U-shaped ring 5 to lift the goods. Moving pulleys 4 are fixedly installed at both ends of the bottom surface of the I-beam bottom beam 1. After the lifting mechanism 6 lifts the goods, the entire device can be pushed to the required position, and finally the lifting mechanism 6 can be allowed to put down the goods.

[0024] According to a further optimized solution, oblique I-beams 7 are symmetrically and detachably installed on both sides of the vertical supporting I-beam 2 , and one end of the oblique I-beam 7 away from the vertical supporting I-beam 2 is detachably connected to the top surface of the I-beam bottom beam 1 .

[0025] The oblique I-beam 7 and the I-beam bottom beam 1, and the oblique I-beam 7 and the vertical supporting I-beam 2 are also connected through the I-beam connector 10 and the anchor bolts 11. The I-beam connector 10 is also bent into a suitable angle to adapt to the angle between the oblique I-beam 7 and the I-beam bottom beam 1 and the angle between the oblique I-beam 7 and the vertical supporting I-beam 2; the connection principle is the same as the connection method between the above-mentioned I-beam bottom beam 1 and the vertical supporting I-beam 2.

[0026] In another embodiment of the present application, the I-beam bottom beam 1, the vertical supporting I-beam 2 and the oblique I-beam 7 are fixedly connected to each other by welding to form a whole, which reduces the installation steps. Before use, it is only necessary to fix the transverse supporting I-beam 3 to the top of the two vertical supporting I-beams 2, which is faster.

[0027] According to a further optimization scheme, a movable pulley brake 8 is fixedly installed on the bottom surface of the I-beam bottom beam 1 near the movable pulley 4 .

[0028] The movable pulley brake 8 can lock the movable pulley 4 and prevent the movable pulley 4 from moving, thereby preventing the device from moving after lifting a heavy object, making the device more stable during operation.

[0029] To further optimize the solution, the I-beam bottom beam 1, the vertical supporting I-beam 2, the horizontal supporting I-beam 3 and the oblique I-beam 7 are all made of No. 18 I-beam.

[0030] No. 18 I-beam is made of high-strength high-quality steel, has good weather resistance and corrosion resistance, can be used in various harsh environments, and has high tensile strength and bending strength, can withstand large loads, and is suitable for the design and construction of various building structures. The application of this utility model can improve the firmness of the device.

[0031] According to a further optimization scheme, a plurality of connecting angle steels 9 are horizontally arranged between the two I-beam bottom beams 1 . The connecting angle steels 9 are perpendicular to the I-beam bottom beam 1 , and both ends of the connecting angle steels 9 are detachably connected to the two I-beam bottom beams 1 .

[0032] The connecting angle steel 9 is parallel to the transverse supporting I-beam 3, and the connecting angle steel 9 is also connected with the I-beam connector 10 and the anchor bolt 11. Through holes 12 are opened at both ends of the connecting angle steel 9, and threaded holes are opened at corresponding positions on the I-beam bottom beam 1. The anchor bolt 11 passes through the through holes 12 and is threadedly connected with the threaded holes; the position where the connecting angle steel 9 is set needs to ensure that it will not affect the movement of the lifted goods.

[0033] The utility model can be assembled on site at the construction site according to the prepared assembly instructions. After the assembly is completed, the heavier materials can be hoisted at the construction site. That is to say, during use, the utility model can transport separate relatively small accessories to the construction site for assembly, and can be moved in a small range through the mobile pulley. It has good use value in limited, narrow and irregular operating space that is not conducive to large vehicle-mounted hoists. It has the advantages of simple operation, easy use, low labor consumption, fast construction progress, high construction quality, and effective savings in construction machinery costs.

[0035] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
