Description

Technical Field

[0001] The utility model relates to the field of cranes, in particular to a single-girder semi-gantry crane. Background Art

[0002] A semi-gantry crane is a type of crane. One side of the outrigger is supported on the ground, and the other side of the end beam is supported on a factory building or a trestle. The main girder spans above the working area, forming a semi-gantry appearance. The outrigger travels on the ground track and cooperates with the end beam on the factory building or trestle to drive the main girder to move in the working area, and a combined electric hoist is used to lift heavy objects.

[0003] The single-girder semi-gantry crane in the factory building is divided into two installation methods for the inner and outer sites. The traveling track of the end beam in the factory is installed on the skeleton, and the outside is installed on the wall. However, sundries are likely to appear in the track on the outer wall of the factory building, resulting in an uneven traveling surface of the end beam in the track, which may cause unstable operation. Summary of the Utility Model

In addition, the device can also include other orientations (such as rotating 90 degrees or other orientations), and the spatial description terms used herein are accordingly interpreted.

[0032] Please refer to Figures 1-4 , a single-main-beam semi-gantry crane, including a main beam 1, an end beam moving mechanism 2, a pipe fitting 3, a support member 4, an air inlet assembly 5 and a traveling assembly 6. The end beam moving mechanism 2 is arranged on the main beam 1, the pipe fitting 3 is arranged on the end beam moving mechanism 2, the support member 4 is arranged on the air inlet side of the pipe fitting 3, the air inlet assembly 5 is arranged on the support member 4 and extends into the pipe fitting 3 at one end, and the traveling assembly 6 is arranged on the end beam moving mechanism 2 and contacts the other end of the air inlet assembly 5.

[0033] In the prior art, one side end beam of a single-girder semi-gantry crane moves on the plant track structure, and the other side support leg is adapted to move on the ground track. It hoists and transfers heavy objects within the working area. In this embodiment, based on the end beam moving mechanism 2 running on the plant track structure, a pipe fitting 3 is installed at one end in its starting forward direction. The pipe fitting 3 is located above the track structure. The walking assembly 6 contacts the plant wall. When the end beam moving mechanism 2 moves on the track structure, the walking assembly 6 moves along with the plant wall and contacts the air inlet assembly 5 to make it rotate on the support member 4, suck air into the pipe fitting 3, and discharge it from the other end along the channel of the pipe fitting 3 to clean the sundries in the track structure, realizing the stable movement of the end beam of the single-girder semi-gantry crane on the plant.

[0034] Please refer to Figures 1-4 , the pipe fitting 3 includes an air guide pipe box 31 arranged at the end of the end beam moving mechanism 2. A reinforcing block is arranged between the air guide pipe box 31 and the end beam moving mechanism 2. A blow pipe head 32 is arranged at the air outlet of the air guide pipe box 31.

[0035] When the above pipe fitting 3 discharges air to clean the sundries on the plant track structure, the air guide pipe box 31 of the pipe fitting 3 is arranged with an air inlet at the vertical top end and an air outlet at the bottom end. The blow pipe head 32 at the bottom air outlet is designed with a narrow upper part and a wide lower part. The wide end of the blow pipe head 32 is inclined downward towards the plant track structure. In this way, the incoming air flows along the air guide pipe box 31 to the blow pipe head 32 and is sprayed obliquely to blow off the sundries in the track structure.

[0036] Please refer to Figures 1-4 , the support member 4 includes an outer frame 41, a rotating seat 42 and a filter screen 43. The outer frame 41 is arranged at the air inlet of the air guide pipe box 31. The rotating seat 42 is arranged inside the outer frame 41. The filter screen 43 is arranged in the space between the rotating seat 42 and the outer frame 41.

[0037] Based on the air inlet at the upper end of the air guide pipe box 31, in this embodiment, the filter screen 43 is blocked at the air inlet of the air guide pipe box 31 through the outer frame 41 and the rotating seat 42. When the end beam moving mechanism 2 is in a stationary state, it can isolate the dust settling with the air and prevent it from adhering and accumulating on the air guide pipe box 31 and the air inlet assembly 5.

[0038] Please refer to Figures 1-4 , the air inlet assembly 5 includes a central shaft 51 arranged on the rotating seat 42. The central shaft 51 extends to one end of the air guide pipe box 31 and is provided with a fan blade 52 arranged in an annular array. A transmission wheel 53 is arranged at the other end of the central shaft 51.

[0039] The above air inlet assembly 5 operates to suck air driven by the walking assembly 6. The air inlet assembly 5 is cooperated with the walking assembly 6 through the transmission wheel 53 outside the central shaft 51 to drive the central shaft 51 to make the fan blade 52 rotate in the air guide pipe box 31, introduce the air through the filter screen 43 into the air guide pipe box 31, and convey it to the blow pipe head 32.

[0040] Considering that the air inlet direction of the existing fan blades is fixed, there will still be a weak reverse air inlet when it rotates in reverse. Therefore, in this embodiment, the air blowing pipe head 32 is located above the movement path of the end beam moving mechanism 2, and a dust-proof net is provided at the air outlet of the air blowing pipe head 32. When the end beam moving mechanism 2 moves in reverse, the traveling assembly 6 drives the transmission wheel 53, driving the central shaft 51 to make the fan blades 52 rotate in reverse. Finally, air enters through the dust-proof net at the air outlet of the air blowing pipe head 32, realizing the prevention of dust from entering the air duct box 31 when the end beam moving mechanism 2 moves in reverse.

[0041] Please refer to Figures 1-4 , the traveling assembly 6 includes a rotating shaft 61 and traveling wheels 62. An installation seat is provided at the end of the end beam moving mechanism 2, and a connection hole is formed in the reinforcing block. The rotating shaft 61 is arranged on the installation seat, and the rotating shaft 61 passes through the reinforcing block through the connection hole. The traveling wheels 62 are arranged on the rotating shaft 61, and the traveling wheels 62 are in contact with the transmission wheel 53.

[0042] It should be noted that the operating speed of the crane is generally slow. By driving the transmission wheel 53 through the movement of the traveling wheels 62 on the factory building wall, the diameter of the traveling wheels 62 should be larger than that of the transmission wheel 53. In this way, the traveling wheels 62 move slowly on the rotating shaft 61 along with the end beam moving mechanism 2, enabling the transmission wheel 53 to drive the fan blades 52 at a relatively fast speed to suck air into the air duct box 31.

[0043] When the above-mentioned traveling wheels 62 and transmission wheel 53 move on the air duct box 31, a protective cover 7 is provided on the end beam moving mechanism 2 of this embodiment. The traveling wheels 62 and the transmission wheel 53 are located below the protective cover 7. The protective cover 7 with an isosceles trapezoid cross-section is arranged above, and at the same time, the side close to the factory building wall is open, cooperating with the movement of the traveling wheels 62 on the wall to protect the traveling wheels 62 and the transmission wheel 53.

[0044] Considering that the traveling wheels 62 travel on the factory building wall and may be deformed and damaged under slight displacement of the end beam moving mechanism 2, therefore, a channel steel 8 is provided on the end beam moving mechanism 2 of this embodiment, and a guide wheel 9 is provided on the channel steel 8. By using the guide wheel 9 to assist the movement of the end beam moving mechanism 2 along the factory building wall, the movement of the traveling wheels 62 can be assisted, reducing the possibility of deformation and damage of the traveling wheels 62.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
