Abstract
The invention discloses a trolley roller assembly. The trolley roller assembly comprises a roller and a roller support for fixing the roller, and is characterized by also comprising a vertically arranged fixing plate, and the roller support is in a U shape, and the opening of the roller support is arranged towards the horizontal direction; the roller is horizontally arranged between upper and lower horizontal plates of the roller support, and a vertical plate of the roller support is fixedly connected with the lower part of the vertically arranged fixing plate; and the upper part of the fixing plate is arranged on a fixing rod arranged on the bottom surface of a tower arm in a welding way. The trolley roller assembly provided by the invention has the advantages that the roller is arranged in the U-shaped roller support of which the opening is arranged towards the horizontal direction, accordingly, if a roller bearing is damaged, the roller can fall on the horizontal plates of the roller support and can not fall from a height, and thus the safety of use is improved; and the roller support is horizontally and fixedly connected onto the fixing plate, and the fixing plate is also arranged on the fixing rod in a welding way, accordingly, compared with the original situation that the roller support is directly fixedly arranged on the fixing rod through bolts, the connecting mode provided by the invention is more reliable.
Description
Technical field
The present invention relates to a kind of trolley idler wheels assembly, be specifically related to a kind of trolley idler wheels assembly that is arranged on the arm frame of tower crane lower edge, belong to hoisting crane and make the field.
Background technology
General crane arm from peaceful arm tower machine is for just putting the triangular-section, and the roller of crane carriage moves at two lower edges of jib.
See figures.1.and.2, existing trolley idler wheels assembly, it includes: roller 101, and roller support 102.Roller 101 and roller support 102 be anti-the holder in the bottom surface of fixed link 103 all, if roller bearing is damaged, then roller 101 directly falls; If the bolt looseness of roller support lost efficacy, then there are great potential safety hazard in roller support 102 and roller 101 conjuncted falling.
Summary of the invention
Be to solve the deficiencies in the prior art, even the object of the present invention is to provide a kind of safe and reliable roller bearing to damage also not exist the fall trolley idler wheels assembly of phenomenon of roller.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of trolley idler wheels assembly comprises: roller, and the roller support of fixing aforementioned roller, it is characterized in that, also comprise: the adapter plate that vertically arranges, aforementioned roller support is the U font, opening is towards horizontal direction, between the up and down two blocks of horizontal plates that are arranged on roller support of roller level; The vertical plate of roller support is fixedly connected on the bottom of the adapter plate of vertical setting.
Aforesaid trolley idler wheels assembly is characterized in that aforementioned roller support and adapter plate are bolted to connection.
Aforesaid trolley idler wheels assembly is characterized in that, the number of aforementioned bolt is 4, and is distributed on four angles of rectangle.
Aforesaid trolley idler wheels assembly is characterized in that, the top of aforementioned adapter plate is welded on the fixed link of bottom surface of tower arm.
Aforesaid trolley idler wheels assembly is characterized in that the weld of aforementioned adapter plate and fixed link scribbles protective paint.
Usefulness of the present invention is: roller is arranged on is U font and opening in the roller support of horizontal direction, if roller bearing is damaged, roller can drop on the horizontal plate of roller support, and the situation from falling from high altitude can not occur, and has improved the safety of using; Being fixedly connected on the adapter plate of fixed bearing level, adapter plate are welded on again on the fixed link, compare with original directly fixed bearing being bolted on the fixed link, and connection mode of the present invention is more reliable.

Fig. 4 is the left view of dolly roll wheel assembly among Fig. 3.
The implication of Reference numeral among the figure: 101-roller, 102-roller support, 103-fixed link, 201-roller, 202-roller support, 203-adapter plate, 204-horizontal plate, 205-vertical plate, 206-bolt, 207-fixed link.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
With reference to Fig. 3 and Fig. 4, trolley idler wheels assembly of the present invention comprises: roller 201, the roller support 202 of fixed idler whell 201, and the adapter plate 203 that vertically arranges.Wherein, roller support 202 is the U font, and opening is towards horizontal direction, between the up and down two blocks of horizontal plates 204 that are arranged on roller support 202 of roller 201 levels; 205 of the vertical plates of roller support are fixedly connected on the bottom of the adapter plate 203 of vertical setting.
Trolley idler wheels assembly of the present invention, be U font and opening in the roller support 202 of horizontal direction because roller 201 is arranged on, if roller bearing is damaged, roller 201 can drop on the horizontal plate 204 of roller support, situation from falling from high altitude can not occur, and has improved the safety of using.
As a kind of preferred scheme, roller support 202 is captiveed joint by bolt 206 with adapter plate 203, is convenient for changing roller support 202.
More preferably, the number of bolt 206 is 4, and be distributed on four angles of rectangle, has effectively guaranteed the steadiness that is connected between roller support 202 and the adapter plate 203.
In the present invention, connection mode between the fixed link 207 of the bottom surface of adapter plate 203 and tower arm, the preferred employing welded, concrete, the top of adapter plate 203 is welded on the fixed link 207, adopt the mode of welding to be fixed connection, so that trolley idler wheels assembly of the present invention is more durable, use safer.
More preferably, adapter plate 203 scribbles protective paint (not shown) with the weld of fixed link 207.Protective paint can effectively reduce wind, frost, rainwater, daylight etc. to the erosion of weld, thereby prolongs the service life of roll wheel assembly, and guarantees the safety of its use.
Need to prove, above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
