Abstract
The utility model discloses a single girder overhead crane, which comprises a main girder and the end girders connected with two ends of the main girder. Through a connecting pipe which is horizontally arranged in the ends of the main girder, the end girders at one end or two ends of the main girder of is connected in transitional way with the setting hole of the end girders. A girder box of the main girder is an integral frame structure of cold pressure. An inner groove is respectively arranged in the plate surface of a left side plate, a right side plate and a top plate, which provides the main girder with better bearing strength. The utility model has following features. The connecting pipe horizontally arranged in the ends of the main girder through one end of the main girder is in transition fit connection with the setting hole of the end girders; therefore The purpose of automatic adjusting the horizontal plane of the end girders is realized. Problem of twist deformation in the main girder is resolved, which is caused by manufacturing error, welding stress and deformation and long time operation leading to that fact that four road wheels are not in the same horizontal plane. The girder box of the main girder is set as an integral frame structure of cold pressure, which overcomes the defect that the frame structure splicing with the traditional main girder box often influences bearing of the main girder.
Description
Technical field
The utility model relates to elevator machinery, especially relates to the single-beam crane that moves along two side rails.
Background technology
Single-beam crane is widely used in industrial and mining enterprises, is the requisite lifting appliance of industrial and mining enterprises' production site, and it is to carry weights such as workpiece by four driving wheels that are arranged on the end carriage of two ends along the fixed guide parallel motion.Single-beam crane because manufacturing errors, welding stress deformation and often between use can cause four wheel faces not on same horizontal surface, traditional single-beam crane is owing to all be to connect as one by tie bolt is rigid between girder and the two ends end carriage, therefore this reduces service life with regard to the torsional deflection that causes girder, and has potential safety hazard.
The utility model content
The utility model purpose is to provide a kind of single-beam crane that can the automatic compensation road wheel be in same horizontal surface; Novel another purpose of this use is not increase its loading strength of raising under the girder deadweight condition.
For achieving the above object, the utility model can be taked following technical proposals:
Single-beam crane described in the utility model, the end carriage that comprises girder and be connected to the girder both ends, the end carriage of described girder one or both ends is connected with end carriage mounting hole transition fit by the connection pipe that is horizontally set on the girder end.
The beam box of described girder is the integral body framed structure of colding pressing; On the plate face of the left and right side plate of described beam box and top board, be respectively arranged with inner groovy vertically, can make the loading strength of girder better.
The utility model advantage is the one or both ends of girder are connected with end carriage mounting hole transition fit by the connection pipe that is horizontally set on the girder end, thereby realize the purpose of self-regulated end carriage horizontal surface, solved because of manufacturing errors, welding stress deformation and long-time the use and cause four road wheels not cause girder torsional deflection problem at same horizontal surface; The beam box of girder is set to the integral body framed structure of colding pressing, and has overcome the framed structure of traditional girder beam box spicing forming type and influences the defective of girder load-bearing; On the plate face of the left and right side plate of described beam box and top board, be respectively arranged with inner groovy vertically, can play the effect of reinforced rib, make the loading strength of girder better, and saved the raw MAT'L of girder, the deadweight that has alleviated girder greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the beam box section-drawing of girder described in the utility model.
The specific embodiment
As shown in the figure, single-beam crane described in the utility model, the end carriage 2 that comprises girder 1 and be connected to girder 1 both ends, the end carriage of described girder 1 one ends is combined as a whole by tie bolt and girder 1, and the end carriage 2 of the other end is connected with end carriage 2 mounting hole transition fit by the connection pipe 3 that is horizontally set on girder 1 end.Be to improve the loading strength of girder 1, the beam box of girder 1 is the integral body framed structure of colding pressing; When being provided with inner groovy 4,5,6 vertically on the plate face of the left and right side plate of beam box and top board, the loading strength of its girder can be better.
