Abstract
The utility model belongs to engineering machinery, and relates to big and small arms of a small digging machine. The utility model is composed of two mutually parallel lateral plates, and a roof plate and a bottom plate which are connected with the upper and lower edges of the lateral plate. A plurality of shaft sleeves are connected between the two lateral plates vertically with the two lateral plates. An inner cavity which is formed by the two lateral plates, the roof plate and the bottom plate is provided with several supporting plates which are vertical with the lateral plates. Two side edges of the supporting plate are fixed to the two lateral plates. At Least, one strip of edge of one of the supporting plate is connected with the outerwall of the shaft sleeve. The utility model enhances the integral structural strength of the big and small arms. A distortion and a fracture are not easily appeared. Simultaneously the requirements of material is lower, and the big and small arms of a small digging machine are helpful to reduce the cost.
Description
Technical field
The utility model belongs to engineering machinery, relates to a kind of big and small arms of mini-excavator.
Background technology
The big forearm of existing excavator generally comprises two side plates that are parallel to each other, top board by two ends about it between the biside plate is connected with base plate, in the inboard of biside plate and top board and base plate, except being connected with several axle sleeves vertical with biside plate, other parts are cavity.Because excavator is when work, its big and small arms will be born very big moment, thereby existing said structure is very high to the requirement of the strength of materials, the necessary higher special rolling-mill section of use cost, even so, its bulk strength is still not high yet, is prone to problems such as distortion, fracture in use.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of lower to material requirements, simultaneously the big and small arms of the mini-excavator of structural strength height, not yielding or fracture.
The big and small arms of mini-excavator of the present utility model includes the side plate that is parallel to each other and is connected the side plate top board and the base plate of edges at two ends up and down, between biside plate, also be connected with several axle sleeves vertical with biside plate, in the inner chamber that biside plate and top board and base plate surround, also be provided with a plurality of gripper shoes vertical with biside plate, the dual-side of gripper shoe and two side plates are connected and fixed.In described each gripper shoe, have at least an edge of a gripper shoe to be connected with the outer wall of above-mentioned axle sleeve.
The utility model is owing to be provided with gripper shoe in the inner chamber of big and small arms, make whole big arm or forearm be separated into a plurality of stress unit, avoided concentrating stressed, thereby improved its overall construction intensity, thereby be not prone to distortion, phenomenon of rupture, also lower to the requirement of material simultaneously, help reducing cost.

Fig. 2 is the plan structure schematic diagram of Fig. 1;
Fig. 3 is the structural representation of forearm of the present utility model;
Fig. 4 is the plan structure schematic diagram of Fig. 3.
The specific embodiment
As shown in the figure, surround an inner chamber between the side plate 1 of the big and small arms of mini-excavator of the present utility model and top board 2 and the base plate 3, in inner chamber except several axle sleeves vertical with biside plate 4 are arranged, also be provided with a plurality of gripper shoes vertical with biside plate 5, the dual-side of gripper shoe and two side plate welding are fixing.In each gripper shoe 5, have at least an edge of a gripper shoe to be connected (as Fig. 1, Fig. 3) with the outer wall of axle sleeve 4.
Claims (2)
1, a kind of big and small arms of mini-excavator, include the side plate (1) that is parallel to each other and be connected the side plate top board (2) and the base plate (3) of edges at two ends up and down, between biside plate, also be connected with several axle sleeves vertical (4) with biside plate, it is characterized in that: in the inner chamber that biside plate and top board and base plate surround, also be provided with a plurality of gripper shoes vertical with biside plate (5), the dual-side of gripper shoe and two side plates (1) are connected and fixed.
2, the big and small arms of mini-excavator according to claim 1 is characterized in that: in described each gripper shoe (5), have at least an edge of a gripper shoe to be connected with the outer wall of axle sleeve (4).
