Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
In one embodiment of the main beam structure of the single-beam bridge crane of the present invention as shown in fig. 1, 2 and 3, the main beam structure comprises a cross beam 1; the bottom of the beam 1 is provided with a slide rail 2; the sliding rail 2 is provided with an electric hoist 3; the slide rail 2 comprises a bottom plate 21 and a web plate 22; two sides of the web plate 22 are respectively connected with a dust guard 23. Through setting up the dust guard, reduced the contact of apparatus with the air dust, the risk that the dust accumulates on the effectual retrieval slide rail.
Specifically, the electric hoist 3 is provided with a through hole 31 along the length direction thereof; cleaning belts 25 are respectively arranged at two sides of the web plate 22; the cleaning belt 25 passes through the through hole 31, and two ends of the cleaning belt are fixed at two ends of the sliding rail 2; the bottom of the cleaning belt 25 contacts the top surface of the base plate 21. The design of cleaning the area is more thorough clears up the dust on the slide rail, further reduces the influence of dust to the apparatus use.
Specifically, the cleaning belt 25 is provided with a plurality of magnetic blocks 26 at intervals. The design of magnetic path can make the cleaning belt more closely laminate on the web, and the electric hoist is to driving the cleaning belt in sliding, reaches the slide rail face of biggest effect and cleans.
Specifically, a brush is provided at the bottom of the cleaning belt 25.
Specifically, the dust-proof plate 23 may be hinged to the web 22, and a positioning plate 24 for supporting the dust-proof plate 23 is disposed between the dust-proof plate 23 and the bottom plate 21. The dust guard is hinged, so that the dust guard can be conveniently moved after the electric hoist is in fault, and the maintenance work is facilitated.
Specifically, the dust-proof plate 23 includes a horizontal section 231, a vertical section 232; the width of the horizontal section 231 is not less than half of the width of the electric hoist 3; the width of the positioning plate 24 is not less than half of the width of the horizontal section 231.
Specifically, a plurality of reinforcing ribs 11 are provided at intervals in the longitudinal direction in the cross member 1.
The working principle is as follows: the user passes behind two cleaning belt 25 the through-hole 31 of electric hoist 3, fixes the both ends of cleaning belt 25 on the both ends face of slide rail, installs electric hoist 3 after, puts down dust guard 23, and dust guard 23 can not collide with electric hoist 3 under the support of locating plate 24, does not influence electric hoist 3's reciprocating motion.
The cleaning belt 25 and the web plate form a cavity under the action of the through hole 31 of the electric hoist 3, the cleaning belt 25 is attached to the web plate of the slide rail 22 under the action of the magnetic block 26 in the front of the advancing direction of the electric hoist 3, the cleaning belt 25 attached to the front is pulled open by the electric hoist 3 in the motion of the electric hoist 3, the cleaning belt 25 at the rear is attached to the web plate 22 under the action of the magnetic block 26 again due to the reduction of the distance between the cleaning belt 25 and the web plate 22, and therefore the cleaning surface for driving the cleaning belt 25 to clean the slide rail 2 is maximum by separating the magnetic block 26 every time, and the electric hoist 3 can be cleaned in a reciprocating mode.
The design structure is simple and reasonable, the dust accumulation is reduced to a great extent, the sliding rail is cleaned in time, the sliding rail is kept clean, the use efficiency is improved, and the damage risk of instruments is reduced.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
