Abstract
The utility model relates to wheel crane and girder thereof, wheel crane comprises electric block and girder, electric block comprises the left lateral travelling wheel and right lateral travelling wheel that pivot center extends in left-right direction, girder comprises the U-lag that notch length down extends along the longitudinal direction, a left side for U-lag, the horizontal link plate being installed with length and extending along the longitudinal direction is welded in the lower end of right cell wall, the left end of horizontal link plate protrudes from described left cell wall and forms the left track for described left lateral travelling wheel orienting roll force fit, the right-hand member of horizontal link plate protrudes from described right cell wall and forms the right track for described right lateral travelling wheel orienting roll force fit.The utility model solves in prior art and causes weld seam many because welding oblique side plate and tiltedly side plate angle of inclination not easily ensures and causes the problem that girder make efficiency is low.
Description
Technical field
The utility model relates to wheel crane in weight-lifting equipment and girder thereof.
Background technology
The girder that hoisting crane comprises electric block and extends along the longitudinal direction, the structure of girder is as shown in Figure 1: comprise notch U-lag 1 down, the lower end of U-lag is welded with by left tiltedly side plate, right tiltedly side plate 2 I-beam section 3 extended along the longitudinal direction, the upper end of left and right oblique side plate is fixedly welded on U-lag, and the upper end of I-beam section is fixedly welded on left and right oblique side plate.It is walk before and after track that the left and right road wheel of electric block is mounted on I-beam section and with I-beam section.Existing this girder Problems existing is: by oblique side plate bag solder together between I-beam section and U-lag, this Type of Welding complex structure, the angle of inclination of left and right oblique side plate is difficult to ensure, make loaded down with trivial details, weld seam is many, and production efficiency is low, and the top of I-beam section is wrapped in inside oblique side plate simultaneously, cause the material behavior of I-beam section not play completely, there is certain waste.
Summary of the invention
The purpose of this utility model is to provide a kind of girder, causes weld seam many and tiltedly side plate angle of inclination not easily ensures and causes the problem that girder make efficiency is low to solve in prior art because welding oblique side plate; The purpose of this utility model is also to provide a kind of wheel crane using this girder.
In order to solve the problem, in the utility model, the technical scheme of wheel crane is:
Wheel crane, comprise electric block and girder, electric block comprises the left lateral travelling wheel and right lateral travelling wheel that pivot center extends in left-right direction, girder comprises the U-lag that notch length down extends along the longitudinal direction, the horizontal link plate being installed with length and extending along the longitudinal direction is welded in the lower end of the left and right cell wall of U-lag, the left end of horizontal link plate protrudes from described left cell wall and forms the left track for described left lateral travelling wheel orienting roll force fit, and the right-hand member of horizontal link plate protrudes from described right cell wall and forms the right track for described right lateral travelling wheel orienting roll force fit.
The groove bottom wall of described U-lag is installed with leg-of-mutton reinforced rib with all welding between left and right sidewall.
The technical scheme of middle girder of the present invention is:
The girder of wheel crane, comprise the U-lag that notch length down extends along the longitudinal direction, the horizontal link plate being installed with length and extending along the longitudinal direction is welded in the lower end of the left and right cell wall of U-lag, the left end of horizontal link plate protrudes from described left cell wall and forms the left track of the left lateral travelling wheel orienting roll force fit for corresponding electric block, and the right-hand member of horizontal link plate protrudes from described right cell wall and forms the right track of the right lateral travelling wheel orienting roll force fit for described electric block.
The groove bottom wall of described U-lag is installed with leg-of-mutton reinforced rib with all welding between left and right sidewall.
The beneficial effects of the utility model are: in the utility model, the left end of horizontal link plate protrudes from described left cell wall and forms the left track that the left lateral travelling wheel roll extrusion for corresponding electric block coordinates, the right-hand member of horizontal link plate protrudes from described right cell wall and forms the right track that the right lateral travelling wheel roll extrusion for electric block coordinates, so to realize the smooth walking of electric block, horizontal link plate is directly fixedly welded on a left side for U-lag, right cell wall lower end, do not need to arrange oblique side plate and I-beam section, horizontal link plate only need weld twice weld seam with between U-lag, and the level angle of horizontal link plate is easy to ensure, thus simplify structure and the production process of girder, substantially increase the make efficiency of girder.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model background technology middle girder;
Fig. 2 is the structural representation of an embodiment of the utility model middle girder.
Detailed description of the invention
The embodiment of wheel crane is as shown in Figure 2: wheel crane comprises electric block and girder, girder comprises the U-lag 5 that notch length down extends along the longitudinal direction, U-lag 5 comprises groove bottom wall 4 and is positioned at left side wall 6 and the right side wall 7 of the groove bottom wall left and right sides, the groove bottom wall of U-lag is with left, between right side wall, all welding is installed with triangle reinforced rib 11, left, the horizontal link plate 10 being installed with length and extending along the longitudinal direction is welded in the lower end of right cell wall, electric block comprises the left lateral travelling wheel and right lateral travelling wheel that pivot center extends in left-right direction, electric block also comprises the movable motor driving left lateral travelling wheel or right lateral travelling wheel to rotate, the left end of horizontal link plate protrudes from left cell wall and forms the left track 9 for left lateral travelling wheel orienting roll force fit, the right-hand member of horizontal link plate protrudes from right cell wall and forms the right track 8 for right travelling wheel orienting roll force fit.
Girder in the utility model is when making, directly horizontal link plate is fixedly welded on the lower end of left and right cell wall, welding twice weld seam is only needed between U-lag and horizontal link plate, weld seam quantity is few, and the level angle of horizontal link plate is easy to ensure, therefore substantially increase the make efficiency of girder, left and right road wheel lays respectively at the left and right sides of U-lag in addition, increase the spacing between two road wheels like this, more contribute to improving the stability in road wheel operational process; U-lag acts on direction of pull on horizontal link plate upward, and road wheel acts on pressure direction on horizontal link plate down, does not so just have the component on other direction, is conducive to the service life of the horizontal link plate of guarantee.
The embodiment of the girder of hoisting crane is as shown in Figure 2: the concrete structure of girder is identical with the girder described in above-mentioned each hoisting crane embodiment, is not described in detail in this.
