Abstract
The utility model discloses a trolley roller component which comprises a roller and a roller support for fixing the roller. The trolley roller component is characterized by further comprising a fixing plate which is vertically arranged; the roller support is U-shaped; the opening of the roller support faces towards the horizontal direction; the roller is horizontally arranged between upper and lower horizontal plates of the roller support; a vertical plate of the roller support is fixedly connected with the lower part of the fixing plate which is vertically arranged; the upper part of the fixing plate is welded with a fixing rod at the bottom surface of a tower arm. The trolley roller component has the beneficial effects that as the roller is arranged in the roller support which is U-shaped and opened towards the horizontal direction, then the roller can fall on the horizontal plates of the roller support if a roller bearing is damaged, the accident that the roller falls down from high above is prevented, and the use security is improved; the fixing support is horizontally and fixedly connected with the fixing plate, and the fixing plate is further welded with a fixing rod, so that compared with the conventional trolley roller component that the fixing support is directly fixed on the fixing rod through bolts, the trolley roller component is more reliable in connection mode.
Description
Technical field
The utility model relates to a kind of trolley idler wheels assembly, is specifically related to a kind of trolley idler wheels assembly be arranged on the arm frame of tower crane lower edge, belongs to hoisting crane and manufactures field.
Background technology
The general crane arm from peaceful arm tower machine is for just putting triangular-section, and the roller of crane carriage moves on 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, roller 101 directly falls; If the bolt looseness of roller support lost efficacy, roller support 102 falls with roller 101 is conjuncted, has great potential safety hazard.
The utility model content
For solving the deficiencies in the prior art, even being to provide a kind of safe and reliable roller bearing to damage, the purpose of this utility model do not have the fall trolley idler wheels assembly of phenomenon of roller yet.
In order to realize above-mentioned target, the utility model 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 vertically arranged, aforementioned roller support is the U font, opening is towards horizontal direction, between the two blocks of horizontal plates up and down 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 be 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 utility model is: roller is arranged on and 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, the situation from falling from high altitude can not occur, and has improved the safety of using; Being fixedly connected on adapter plate of fixed bearing level, adapter plate is welded on again on fixed link, and with original directly fixed bearing being bolted on fixed link and comparing, connection mode of the present utility model is more reliable.
The accompanying drawing explanation
Fig. 1 is the structural representation of existing trolley idler wheels assembly;
Fig. 2 is the left view of dolly roll wheel assembly in Fig. 1;
Fig. 3 is the structural representation of a specific embodiment of trolley idler wheels assembly of the present utility model;
Fig. 4 is the left view of dolly roll wheel assembly in Fig. 3.
The implication of Reference numeral in 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 utility model is done to concrete introduction.
With reference to Fig. 3 and Fig. 4, trolley idler wheels assembly of the present utility model comprises: roller 201, the roller support 202 of fixed idler whell 201, and the adapter plate 203 vertically arranged.Wherein, roller support 202 is the U font, and opening is towards horizontal direction, between the two blocks of horizontal plates 204 up and down 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 utility model, due to being arranged on, roller 201 is U font and opening in the roller support 202 of horizontal direction, if roller bearing is damaged, roller 201 can drop on the horizontal plate 204 of roller support, the situation from falling from high altitude can not occur, improved the safety of using.
As a kind of preferred scheme, roller support 202 is fixedly connected with 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 be connected between roller support 202 and adapter plate 203.
In the utility model, connection mode between the fixed link 207 of the bottom surface of adapter plate 203 and tower arm, preferably adopt welding, concrete, the top of adapter plate 203 is welded on fixed link 207, adopt the mode of welding to be fixed connection, make trolley idler wheels assembly of the present utility model 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 the erosion to weld such as wind, frost, rainwater, daylight, thereby extends the service life of roll wheel assembly, and guarantees the safety of its use.
It should be noted that, above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
