Abstract
The utility model discloses a novel arm structure, piece under last piece of fly jib and fly jib, on the fly jib under piece and the fly jib chip bonding to form the cross section be square inner arm together, still include piece under last piece of cantilever crane and the cantilever crane, on the cantilever crane under piece and the cantilever crane chip bonding to form the cross section be square outer arm together, this outer arm movable sleeve is established on the inner arm, be located the periphery of outer arm is provided with the guard shield, form the cavity that supplies the storage between guard shield and the outer arm. Be provided with the one deck guard shield in the outside of cantilever crane, and vacuole formation between guard shield and the cantilever crane for place and connect oil pipe, electric wire or tow chain usefulness, set up a fine protective layer for the cantilever crane like this, and makeed electric wire and oil pipe can both obtain fine conclusion and place. Can dismantle the guard shield by oneself during the maintenance, do not make a sound maintenance and maintenance, and the part on the cantilever crane be more durable, has increased the life of equipment at all.
Description
Technical field
The utility model relates to a kind of Novel arm support structure, belongs to engineering machinery field.
Background technology
The jib form of straight arm type overhead working truck has a variety of, drag chain on jib, electric wire and oil pipe normal conditions are all design outside, just conveniently install, these things are chronically exposed in air, get rusty easily corrosion, it is very fast that electric wire also weares and teares, and can there is potential safety hazard to a certain extent.
Utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of can the Novel arm support structure of convenient for maintaining.
For achieving the above object, the technical solution of the utility model is as follows: a kind of Novel arm support structure, comprises fly jib upper slice and fly jib bottom sheet, and it is square inner arm that described fly jib upper slice and fly jib bottom sheet are welded together to form cross-sectional plane; Also comprise jib upper slice and jib bottom sheet, it is square outer arm that described jib upper slice and jib bottom sheet are welded together to form cross-sectional plane; This outer arm is movably set on inner arm; The periphery being positioned at described outer arm is provided with guard shield, forms the cavity for storing between described guard shield and outer arm.
As preferably, described inner arm is connected by several slide blocks with between outer arm, and forms telescopic jib.The telescopic jib of two joints be made up of inner arm and outer arm its can strengthen the bearing capacity of jib itself, reduce jib distortion, minimizing collection space.
As preferably, described guard shield detouchable is arranged on the periphery of outer arm; And described guard shield is covered by upper cover and side and forms, and described upper cover detouchable is arranged on jib upper slice top, and described side cover detouchable is arranged on the side of outer arm.Described upper cover and side are covered interior for placing oil pipe and electric wire, for placing drag chain in jib bottom sheet, are convenient to the outside line of jib to carry out rational layout and planning like this.
The beneficial effects of the utility model: have one deck guard shield in the outer setting of jib; and form cavity between guard shield and jib; oil pipe, electric wire or drag chain use is connect for placing; be provided with a good protective cover to jib like this, and make electric wire and oil pipe well to be concluded and to place.Can realizing self disassembling guard shield during maintenance, at all do not ring M R, and parts on jib are more durable, add the service life of equipment.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present utility model;
Wherein: 1. fly jib upper slice, 2. fly jib bottom sheet, 3. jib upper slice, 4. jib bottom sheet, 5. guard shield, 6. slide block, 7. upper cover, 8. side cover.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in further detail.
As shown in Figure 1, a kind of Novel arm support structure, comprises fly jib upper slice 1 and fly jib bottom sheet 2, and it is square inner arm that described fly jib upper slice 1 and fly jib bottom sheet 2 are welded together to form cross-sectional plane; Also comprise jib upper slice 3 and jib bottom sheet 4, it is square outer arm that described jib upper slice 3 and jib bottom sheet 4 are welded together to form cross-sectional plane; This outer arm is movably set on inner arm; The periphery being positioned at described outer arm is provided with guard shield 5, forms the cavity for storing between described guard shield 5 and outer arm.
Described inner arm is connected by several slide blocks 6 with between outer arm, and forms telescopic jib.The telescopic jib of two joints be made up of inner arm and outer arm its can strengthen the bearing capacity of jib itself, reduce jib distortion, minimizing collection space.
Described guard shield 5 detouchable is arranged on the periphery of outer arm; And described guard shield 5 covers 8 by upper cover 7 and side to be formed, and described upper cover 7 detouchable is arranged on above jib upper slice 3, and the side that 8 detouchables are arranged on outer arm is covered in described side.Described upper cover 7 and side are covered for placing oil pipe and electric wire in 8, for placing drag chain in jib bottom sheet 4, are convenient to the outside line of jib to carry out rational layout and planning like this.
There is one deck guard shield 5 in the outer setting of jib, and form cavity between guard shield and jib, connecing oil pipe, electric wire or drag chain use for placing, being provided with a good protective cover to jib like this, and making electric wire and oil pipe well to be concluded and to place.Can realizing self disassembling guard shield during maintenance, at all do not ring M R, and parts on jib are more durable, add the service life of equipment.
