Abstract
The utility model proposes a kind of arm extension bracket, comprise square set, carrier base, described square set both sides are provided with spike, are provided with contiguous block bottom described spike, and described spike is fixed on described carrier base by described contiguous block; Wearing bush is provided with between described contiguous block and described carrier base; Described square set both sides are provided with roller frame, described roller frame is provided with support roller, described support roller is across bottom described square set, telescopic boom passes described square set and is pressed on described support roller, the utility model sets up support roller on the square set of hold-down arm bottom, when telescopic boom is stretched, makes the cliding friction between flexible wall and bracket be converted into friction of rolling, reduce the wear intensity of telescopic boom, greatly reduce maintenance cost and energy.
Description
Technical field
The utility model relates to technical field of engineering machinery, especially relates to a kind of arm extension bracket.
Background technology
Along with the fast development of China's economic construction, the demand that material is removed for large-tonnage dress in camp site increases day by day; Maximization is the important design goal of various dress tipping wagons.For telescopic arm crane, the performance of its telescopic boom is most important, directly affect the lifting performance of hoisting crane entirety, in existing technology, common telescopic boom is directly contacting with the support of telescopic boom outside, and the cliding friction that between metal piece, directly contact produces makes telescopic boom be worn, and needs the larger energy of cost and expense to keep in repair, meanwhile, between spike and carrier base also very easily by plucking.
Utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of arm extension bracket, comprising square set, carrier base, described square set both sides are provided with spike, are provided with contiguous block bottom described spike, and described spike is fixed on described carrier base by described contiguous block; Wearing bush is provided with between described contiguous block and described carrier base; Described square set both sides are provided with roller frame, and described roller frame is provided with support roller, and described support roller is across bottom described square set, and telescopic boom passes described square set and is pressed on described support roller.
The further preferred version that the utility model proposes, described wearing bush is copper sheathing.
The further preferred version that the utility model proposes, described roller frame is fixed on described square set by connecting panel.
The arm extension bracket that the utility model proposes has following beneficial effect: 1, on the square set of hold-down arm bottom, set up support roller, when telescopic boom is stretched, the cliding friction between flexible wall and bracket is made to be converted into friction of rolling, reduce the wear intensity of telescopic boom, greatly reduce maintenance cost and energy.
2, between support and carrier base, be provided with copper sheathing, work good between copper sheathing and support and add lubricating oil, effectively prevent wearing and tearing.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is construction profile schematic diagram of the present utility model;
Wherein, 1-square set, 2-carrier base, 3-spike, 4-contiguous block, 5-wearing bush, 6-roller frame, 7-support roller, 8-connecting panel, 9-telescopic boom.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Composition graphs 1,2, the utility model proposes a kind of arm extension bracket, comprise square set 1, carrier base 2, described square set 1 both sides are provided with spike 3, be provided with contiguous block 4 bottom described spike 3, described spike 3 is fixed on described carrier base 2 by described contiguous block 4; Wearing bush 5 is provided with between described contiguous block 4 and described carrier base 2; Described square set 1 both sides are provided with roller frame 6, and described roller frame 6 is provided with support roller 7, and described support roller 7 is across bottom described square set 1, and telescopic boom 9 passes described square set 1 and is pressed on described support roller 7.
When telescopic boom 9 is pressed on and support roller 7 carries out flexible, support roller 7 auxiliary telescopic arm 9 moves, and original cliding friction is become friction of rolling, telescopic boom 9 activity can be made more smooth and easy, also reduce the abrasion factor of telescopic boom 9, greatly reduces maintenance old and the time.
The further preferred version that the utility model proposes, described wearing bush 5 is copper sheathing, and spike 3 inserts in copper sheathing, and copper sheathing can effectively prevent by plucking between steel part, wearing and tearing.
The further preferred version that the utility model proposes, described support roller 7 frame 6 is fixed on described square set 1 by connecting panel 8, and support roller 7 is across on support roller 7 frame 6, produces larger power, uses connecting panel 8 to make installation more firm.
To be apparent for those skilled in the art to the multiple amendment of embodiment, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
