Abstract

The utility model discloses a tunnel boring machine screw conveyer which comprises a through shaft and a screw blade fixed on the through shaft. A plurality of wear resistant blocks are fixedly arranged on the arc-shaped edge of the screw blade. Due to the fact that the wear resistant blocks are arranged on the arc-shaped edge of the screw blade of the tunnel boring machine screw conveyer, the tunnel boring machine screw conveyer has the advantages of being capable of obviously improving abrasion performance of the screw blade, prolonging the service life of the screw blade, reducing frequency of replacement of the screw blade, further reducing frequency of shut-down examination, and reducing production cost of tunneling.

Description

The tunnel boring machine auger loader
Technical field
The utility model relates to a kind of auger loader, is applicable to the earth pressure balance shield machine technical field.
Background technology
At present, along with greatly developing of City Underground Transportation, the application of shield tunnel development machine is increasingly extensive.Earth pressure balance shield machine is when advancing, and the quarrel soil that its front end cutterhead rotary cutting gets off enters native cabin, and when quarrel soil was full of native cabin, soil, hydraulic pressure on its passive soil pressure and the digging face were basic identical, so digging face is realized equilibrium of pressure (namely stable).Quarrel soil leans on the auger loader dispatch to native case, and then is transported to the face of land by equipment such as band conveyors.Auger loader is that the quarrel soil that the spiral of utilization rotation will be transferred carries out transportation work along interior passing of fixing casing.In the course of conveying of quarrel soil, quarrel soil is even more serious to the wearing and tearing of the surface generation of spiral certain wearing and tearing, especially helical margin, thereby has shortened the service life of spiral greatly, therefore presses for the resistance to abrasion that improves helical margin.
The utility model content
Technical problem to be solved in the utility model provides a kind of tunnel boring machine auger loader that can improve the helicallobe resistance to abrasion.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of tunnel boring machine auger loader, comprise axis and the helicallobe that is fixed on the axis, and be fixed with a plurality of wear-resistant blocks on the curved edge of described helicallobe.
Described wear-resistant block comprises wearing layer and matrix; The material of described wearing layer is wear resisting cast iron or wear-resistant steel, and the material of described matrix is dead-soft steel or low-alloy steel; Described wearing layer is captiveed joint by castingin or biliquid forging type with matrix; Described matrix is captiveed joint by welding manner with the curved edge of helicallobe.
The upper and lower surface of described wear-resistant block is arc-shaped curved surface, and its left and right sides face is the plane, and the angle of left and right sides face is that 10 degree are to 30 degree.
Principle of work of the present utility model is as follows:
When auger loader was worked, helicallobe rotated and drives quarrel soil.Because the friction of quarrel soil, the camber line edge of helicallobe constantly is subjected to the wearing and tearing of tiny fragments of stone, coal, etc. soil.Owing to welded wear-resistant block at the curved edge of helicallobe, tumbled in wear-resisting limit together with regard to being equivalent to the curved edge of helicallobe.So just avoid the curved edge of helicallobe to contact with the direct friction of tiny fragments of stone, coal, etc. soil, thereby avoided the wearing and tearing of helicallobe.Since wear-resistant block wearing layer adopt high-abrasive materials such as wear resisting cast iron or wear-resistant steel to make, so resistance to abrasion is good, and is not easy to wear; Because matrix adopting dead-soft steel or the low-alloy steel material of wear-resistant block are made, so weldability is good, can be easily weld with the curved edge of helicallobe, easy to operate, firm welding is reliable.
The beneficial effect that adopts technique scheme to produce is: by the curved edge at the helicallobe of auger loader wear-resistant block is set, can obviously improve the resistance to abrasion of helicallobe, prolong the service life of helicallobe, reduce the number of times of changing rotating blade, that further reduces auger loader stops examining number of times, reduces the productive costs of tunnelling.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is local structure scheme drawing of the present utility model;
Fig. 2 is the structural representation of wear-resistant block described in the utility model;
Wherein, 1, axis, 2, helicallobe, 3, wear-resistant block, 4, wearing layer, 5, matrix.
The specific embodiment
Embodiment as shown in Figure 1 as can be known, tunnel boring machine auger loader described in the utility model comprises axis 1 and is fixed in helicallobe 2 on the axis 1, is fixed with a plurality of wear-resistant blocks 3 on the curved edge of described helicallobe 2.
As shown in Figure 2, above-mentioned wear-resistant block 3 comprises wearing layer 4 and matrix 5; The material of described wearing layer 4 is wear resisting cast iron or wear-resistant steel, and the material of described matrix 5 is dead-soft steel or low-alloy steel; Described wearing layer 4 is captiveed joint by castingin or biliquid forging type with matrix 5; Described matrix 5 is captiveed joint by welding manner with the curved edge of helicallobe 2.
The upper and lower surface of described wear-resistant block 3 is arc-shaped curved surface, and its left and right sides face is the plane, and the angle of left and right sides face is that 10 degree are to 30 degree.The curved edge welding back that the arranging of this angle can guarantee wear-resistant block and helicallobe forms required spiral-shaped.
The principle of work of above-mentioned tunnel boring machine auger loader is as follows:
When auger loader was worked, helicallobe rotated and drives quarrel soil.Because the friction of quarrel soil, the camber line edge of helicallobe constantly is subjected to the wearing and tearing of tiny fragments of stone, coal, etc. soil.Owing to welded wear-resistant block at the curved edge of helicallobe, tumbled in wear-resisting limit together with regard to being equivalent to the curved edge of helicallobe.So just avoid the curved edge of helicallobe to contact with the direct friction of tiny fragments of stone, coal, etc. soil, thereby avoided the wearing and tearing of helicallobe.Since wear-resistant block wearing layer adopt high-abrasive materials such as wear resisting cast iron or wear-resistant steel to make, so resistance to abrasion is good, and is not easy to wear; Because matrix adopting dead-soft steel or the low-alloy steel material of wear-resistant block are made, so weldability is good, can be easily weld with the curved edge of helicallobe, easy to operate, firm welding is reliable.
