Description
Technical field
The excavator-type shovel clamshell excavator that this utility model loess tunnel excavation is special, belongs to excavator-type shovel clamshell excavator technical field.
Background technology
Build tunnel, tunnel in Loess Plateau, the excavation of its face, use arc leading pit or benching tunnelling method to construct more.Main operational approach and step be directly dig out in arch with excavator arc or by excavator go out blank again by artificial pneumatic pick, electric pick or scoop scrape out design require arc.Existing excavator-type shovel clamshell excavator substrate is square, it is impossible to scrape out the arc that arch, tunnel requires, backbreaks serious, not only adds potential safety hazard, and causes concrete spray anchor material and the waste of activity duration；Go out blank with excavator the most dangerous by manual operation again, and operation trouble, work efficiency are low.
Row insider know altogether, in loess tunnel digging process, face excavation is the priority control work of tunneling operation construction, particularly backbreak and potential safety hazard is the most important thing of work, the surrounding rock structure of arc is more stable, the arc excavated with arc base sword with arc substrate adds the contact area of bucket and country rock the most to greatest extent, and can be good at maintaining the rock-steady structure of country rock self, but the most crucial step fails to be well solved all the time.
Utility model content
This utility model overcomes the deficiency that prior art exists, it is provided that a kind of loess tunnel improving excavation efficiency and working security excavates special excavator-type shovel clamshell excavator.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: the excavator-type shovel clamshell excavator that loess tunnel excavation is special, including base plate, side plate, wrapper sheet, flap and torque tube, the both sides of described base plate are provided with side plate, described wrapper sheet is arranged on the upper end connecting portion of base plate, described base plate, side plate and wrapper sheet cooperatively form bucket, the bottom of described wrapper sheet is fixing with base plate to be connected, the upper parallel of described wrapper sheet is provided with two flaps, two groups of torque tubes it have been horizontally disposed with on described flap, it is provided with base sword in the work portion, lower end of described base plate, described base sword and base plate are the most curved, and the two joint portion arc-shaped transition.
Described base sword is consistent with the radian of base plate, is 120 °～135 °.
The front end of described base sword is arcuate structure forward.
Described base sword is linked together with base plate by fastener.
Described base sword hardness is HB400, and the yield strength abrasion-resistant stee more than 1000pa is made.
Described side plate outer rim is surrounded by the sidepiece wearing plate made with potassium steel, in order to increase abrasion resistance and to provide supplementary protection.
This utility model compared with prior art has the beneficial effect that this utility model base plate and base sword are arc, loess tunnel for arc excavates, expand the contact area of bucket and excavation face, it is possible to excavate more accurately and efficiently, decrease the amount of backbreaking；The arc-shaped sections that arc bucket scrapes out simultaneously is conducive to maintaining the stability of country rock self, improves the safety of construction.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described further.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of curved plate in this utility model.
In figure: 1 be base plate, 2 be side plate, 3 be wrapper sheet, 4 be flap, 5 be torque tube, 6 be base sword, 7 for sidepiece wearing plate.
Detailed description of the invention
Such as Fig. 1, shown in Fig. 2, the excavator-type shovel clamshell excavator that this utility model loess tunnel excavation is special, including base plate 1, side plate 2, wrapper sheet 3, flap 4 and torque tube 5, the both sides of described base plate 1 are provided with side plate 2, described wrapper sheet 3 is arranged on the upper end connecting portion of base plate 1, described base plate 1, side plate 2 and wrapper sheet 3 cooperatively form bucket, the bottom of described wrapper sheet 3 is fixing with base plate 1 to be connected, the upper parallel of described wrapper sheet 3 is provided with two flaps 4, two groups of torque tubes 5 it have been horizontally disposed with on described flap 4, it is provided with base sword 6 in the work portion, lower end of described base plate 1, described base sword 6 and base plate 1 are the most curved, and the two joint portion arc-shaped transition.
Described base sword 6 is consistent with the radian of base plate 1, is 120 °～135 °.
The front end of described base sword 6 is arcuate structure forward.
Described base sword 6 is linked together with base plate 1 by fastener.
Described base sword 6 is HB400 by hardness, and the yield strength abrasion-resistant stee more than 1000pa is made.
Described side plate 2 outer rim is surrounded by the sidepiece wearing plate 7 made with potassium steel, in order to increase abrasion resistance and to provide supplementary protection.
In this utility model, base sword 6 is arc, and radian is consistent with base plate 1 radian, makes with the HB400 surrender degree abrasion-resistant stee more than 1000pa, and during work, the special bucket in excavator operation driver operation loader excavator large arm excavates along tunnel camber line.Its arc base sword is maximum at curved leading edge stress, and excavation dynamics is the most maximum, and excavation effect is higher.
This utility model equipped with torque tube 5, loads in order to distribution evenly and increases durability on flap 4.
