Description
[technical field]
The utility model relates to a kind of parts of hoisting crane, relates to a kind of end carriage location structure of hoisting crane specifically.
[background technology]
Crane span structure type hoisting crane is claimed overhead traveling crane again.Common crane span structure type hoisting crane is made up of crane carriage, crane span structure operating unit, crane span structure metal construction; The crane span structure of crane in bridge type vertically moves along being laid on the track of both sides on overhead; Crane carriage laterally moves along the track that is laid on the crane span structure; Constitute the operating range of a rectangle, just can make full use of the space handling material below the crane span structure, do not receive the obstruction of wayside equipment.
The electric block mono beam crane in bridge type is the general-purpose overhead crane that is widely used in commercial production, storage, communications and transportation.Since this pattern hoisting crane compare with other pattern hoisting crane of model of the same race have simple in structure, in light weight, cost is low, easy to maintenance, so this machine is widely used in the various places of indoor and outdoor.Most medium and small sized enterprises all adopt this type of hoisting crane, so this product is that China produces and use maximum hoisting cranes.Real genus amount is big and wide, and national annual turnover is above 100,000.
The electric block mono beam crane in bridge type main frame of producing now is the structural shape of China's the seventies in last century; The employing single crab operating structure that wherein hoisting capacity is little; The employing double trolley operating structure that hoisting capacity is big, girder adopts the I shape steel plate, welded structure behind the end carriage employing steel plate die mould; There is disadvantage in this type hoisting crane: 1, main beam structure is loaded down with trivial details, can not adapt to the mechanization batch manufacturing, and structural section is long-pending can not to be made full use of, and the California bearing ratio ratio of hoisting capacity (deadweight with) is than higher; 2, end carriage is relatively reasonable in design initial, can not adapt to present development need; 3, often produce cliding friction between operating unit wheel rim and the guide rail, running resistance is big, noise is big, loss is big, and wheel and orbit gap produce snakelike when cart moves.
The form single-beam crane of homemade LD type and process improvement and two big types of import are arranged on the market; But all have relative weakness, imported product cucurbit quality is good, but girder is heavy; Snakelike still the failing of cart overcomes; The high general enterprise of price does not think usefulness, the old product low price, but life-span, quality all have weak point.
The dolly of hoisting crane does not generally install track adjusting wheel additional at present, and in the trolley travelling process, wheel wear comes serious; Even useful track adjusting wheel, because the difference of track adjusting wheel, the distance between the track adjusting wheel is difficult for adjustment; Fine setting is more difficult, and exists the adjustment back to be difficult for fixing defective.
[utility model content]
The technical matters that the utility model solves provides the end carriage location structure that the adjustment of a kind of position is accurate, locate the hoisting crane of firm and long service life.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of end carriage location structure of hoisting crane; It is characterized in that the bottom end face of said end carriage is arranged at intervals with two track adjusting wheels side by side, the bottom end face setting of the said end carriage of axis normal of said track adjusting wheel.
Preferably, said track adjusting wheel comprises roller shaft and roller, and said roller is fixed on the bottom end face of said end carriage through roller shaft.
Preferably; Said roller shaft comprises bonded assembly axle top successively, axle bottom and the axle bumper plate that is arranged on a bottom; Said axle top, axle bottom and axle bumper plate are wholely set; So axle top is provided with axle bottom off-axis, is provided with the spline of captiveing joint with the bottom end face of said end carriage on said axle top, said roller is arranged on said axle top or axle bottom.
Preferably, also be provided with an adapter plate between the bottom end face of end carriage and the said roller.
The utility model beneficial effect compared with prior art is: owing to be arranged at intervals with two track adjusting wheels side by side at the bottom end face of end carriage; The bottom end face setting of the said end carriage of axis normal of two track adjusting wheels; The utlity model has the position and adjust accurately, locate firmly, and the advantages such as long service life that can prolong crane end carriage.
[description of drawings]
Accompanying drawing described herein is the further understanding that is used to provide the utility model, constitutes the application's a part, but do not constitute improper qualification the utility model, in the accompanying drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the structure for amplifying scheme drawing of A part shown in Figure 1;
Fig. 3 is the decomposition texture scheme drawing of the utility model track adjusting wheel.
Description of reference numerals: 10a-track adjusting wheel; The 12-roller shaft; 12a-axle top; 12b-axle bottom; 12c-axle bumper plate; The 12d-spline; The 10-roller; The 14-adapter plate; The 20-end carriage.
[specific embodiment]
To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of the utility model, but not as the qualification to the utility model.Referring to accompanying drawing 1, Fig. 2, shown in Figure 3; The utility model discloses a kind of end carriage location structure of hoisting crane; The bottom end face of said end carriage 20 is arranged at intervals with two track adjusting wheel 10a side by side, the bottom end face setting of the said end carriage 20 of the axis normal of said two track adjusting wheel 10a.Said track adjusting wheel 10a comprises roller shaft 12 and roller 10, and said roller 10 is fixed on the bottom end face of said end carriage 20 through roller shaft 12.Said roller shaft 12 comprises bonded assembly axle top 12a successively, axle bottom 12b and the axle bumper plate 12c that is arranged on a bottom 12b; Said axle top 12a, axle bottom 12b and axle bumper plate 12c are wholely set; So axle top 12a is provided with axle bottom 12b off-axis; Be provided with the spline 12d of captiveing joint with the bottom end face of said end carriage 20 at said axle top 12a, said roller 10 is arranged on said axle top 12a or axle bottom 12b.Also be provided with an adapter plate 14 between the bottom end face of end carriage 20 and the said roller 10.
The axle top 12a of the roller shaft 12 of this product and axle bottom 12b are accentrics, can make end carriage running fix accomplish fine setting, shown in accompanying drawing 3.The utility model roller shaft 12 adopts eccentric shaft, and track adjusting wheel 10a is to be connected through bearing with roller shaft 12.The relative position of adjustment roller 10 and top tie plate 14 changes the distance between two track adjusting wheel 10a, plays directional tagging.Roller shaft 12 is that spline 12d is connected with top tie plate 14, and is stressed even, steadily, rational in infrastructure.The roller shaft 12 of this product is splined with the bottom end face of end carriage 20, like this design have be prone to fixing, be prone to adjust, stressed advantage such as even.This product structure design is simple, is convenient to install, and is practical extremely strong with property.Because the bottom end face at end carriage 20 is arranged at intervals with two track adjusting wheel 10a side by side; The bottom end face setting of the said end carriage 20 of the axis normal of two track adjusting wheel 10a; The utlity model has the position and adjust accurately, locate firmly, and the advantages such as long service life that can prolong crane end carriage.
The above in the spiritual category that does not break away from the utility model creation, is familiar with the protection domain that this technological various simple covert and modification that those skilled in the art did still belongs to the utility model only with the convenient the utility model of explaining.
