[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0017] Please see Figures 1 to 3 The embodiments of this utility model include: A simple crane for use in a factory building includes a column 1 and a rotating arm 2, wherein the rotating arm 2 is connected to the top side wall of the column 1, and the column 1 is used to support the entire crane structure.

[0018] The rotating arm 2 can rotate at an angle, cooperating with the electric hoist mounted on it, so that heavy objects can be easily moved to a new position.

[0019] The rotating arm 2 is connected to the top side wall of the column 1 through a quick-connect structure, which makes it easy to install and can be used to move heavy objects in small factory spaces, thus making up for the shortcomings of existing cranes that occupy a lot of space.

[0020] The quick-connect structure includes an upper mounting base and a lower mounting base for mounting the rotating arm 2. The upper mounting base is located at the top of the column 1, and the lower mounting base is located in the middle section of the column 1. The distance between the upper mounting base and the lower mounting base matches the length of the rotating shaft 15 of the rotating arm 2. Both the upper mounting base and the lower mounting base adopt a double-layer mounting plate 3 structure, which reduces the weight of the upper mounting base and the lower mounting base. At the same time, by connecting with the U-shaped block 5 and the annular block 7, the upper mounting base and the lower mounting base meet the heavy load requirements.

[0021] The mounting plate 3 has a first circular hole that is fixed to the column 1. The first circular hole is used for the fixed installation of the quick connection structure and the column 1.

[0022] The upper mounting base adopts a combined structure, which makes the installation of the rotating arm 2 more convenient and quick. During installation, after the bottom of the rotating shaft 15 is installed on the lower mounting base, the T-block 6 limits the top of the rotating shaft 15, and finally locks it in place by the cooperation of the fixing plate 16 and the connecting plate 17.

[0023] A U-shaped groove 4 is provided on one side of the upper mounting base. A U-shaped block 5 that mates with the U-shaped groove 4 is installed between the two mounting plates 3 in the upper mounting base. A T-shaped block 6 is installed at the opening of the U-shaped block 5. The T-shaped block 6 has an arc groove facing the U-shaped groove 4. The T-shaped block 6 and the U-shaped block 5 are locked together by a fixing plate 16 and connecting plates 17 on both sides of the U-shaped block 5. The U-shaped block 5 and the T-shaped block 6 form an upper mounting hole.

[0024] The U-shaped block 5 is used to connect the two mounting plates 3 inside the upper mounting base, so that the upper mounting base is not only lightweight, but also meets the requirements of heavy load.

[0025] A second circular hole is provided on one side of the lower mounting base. An annular block 7 that mates with the second circular hole is installed between the two mounting plates 3 inside the lower mounting base at the location of the second circular hole. The second circular hole and the annular block 7 form a lower mounting hole.

[0026] A reinforcing plate 18 is installed at the bottom of the lower mounting base to reinforce the lower mounting base.

[0027] The annular block 7 is used to connect the two mounting plates 3 inside the lower mounting base, so that the lower mounting base is not only lightweight, but also meets the requirements of heavy load.

[0028] An upper bearing structure and a lower bearing structure are respectively installed in the upper mounting hole and the lower mounting hole. Both the upper bearing structure and the lower bearing structure include a bearing seat 8, a sealing ring 9, a deep groove ball bearing 10, a washer 11, and a flat bearing 12.

[0029] The deep groove ball bearing 10 is used to bear radial force, so that the rotating arm 2 is prevented from drooping due to gravity.

[0030] The planar bearing 12 is used to bear axial force, making the rotating arm 2 rotate more freely and flexibly.

[0031] The washer 11 is used to separate the deep groove ball bearing 10 and the flat bearing 12 to prevent them from affecting each other.

[0032] The two deep groove ball bearings 10 and the two flat bearings 12 are respectively installed on the first connecting section 13 and the second connecting section 14 at the top and bottom of the rotating shaft 15, and the sealing ring 9 is disposed between the deep groove ball bearings 10 and the flat bearings 12.

[0033] The bearing seats 8 in the upper bearing structure and the lower bearing structure are respectively installed on the upper mounting hole and the lower mounting hole with the limiting platform on top. Since the bearing seats 8 are subjected to gravity, the bearing seats 8 can be fixed more firmly by adopting the position with the limiting platform on top.

[0034] The sealing ring 9 in the upper bearing structure is installed at the bottom of the corresponding bearing seat 8, and the sealing ring 9 in the lower bearing structure is installed at the top of the corresponding bearing seat 8.

[0035] Unlike existing technologies, this utility model provides a simple crane for use in factory buildings. The crane adopts a quick-connect structure, which makes it easy to install and can be used to move heavy objects in small factory spaces, thus overcoming the shortcomings of existing overhead cranes that occupy a lot of space.
