Abstract
The utility model discloses a tunnel excavator bucket which comprises a bucket wall plate and bucket side plates. The bucket wall plate and the bucket side plates are welded together to form a bucket-shaped structure. Bucket teeth are fixed under the front end of the bucket wall plate, and the upper end of the bucket wall plate is connected with an upper tooth plate in a welded mode. Dialing and scrabbling teeth which are inclined forward are arranged on the upper tooth plate. The upper tooth plate is welded on the outer side face of the upper end of the bucket wall plate. Outer side reinforcing plates are welded on the outer side face of the bucket wall plate at intervals. The outer side reinforcing plates are strip-shaped plates which are arranged along the width direction of the bucket. Inner side reinforcing plates which are strip-shaped plates are welded on the inner side face of the bucket wall plate at intervals. The tunnel excavator bucket not only can effectively shovel earth and stones, but also can carry out shoveling operation for earth and stones on a vault of a tunnel and on a relative high position. Therefore, the tunnel excavator bucket is suitable for being used in an excavator.
Description
Technical field
The utility model relates to a kind of excavator, relates in particular to the improvement of tunnel excavator scraper bowl structure.
Background technology
Tunnel excavator is the special engineering construction machinery for tunnel excavation.Tunnelling is confidential in the tunnel, finish cubic metre of earth or rock loosening, broken, excavate and the operation such as heap quarrel, have that work plane is narrow, working condition is complicated, execution conditions are poor and the characteristics such as difficulty of construction is large, so the construction requirement of tunnel excavator obviously is different from common ground excavation machinery.
Scraper bowl is the important construction parts that excavator excavates operation, it mainly comprises scraper bowl side plate and curved scraper bowl wallboard, the scraper bowl plate-side plate welding is in the both sides of wallboard, lower front end at wallboard is fixedly welded with bucket tooth, also be fixedly installed the scraper bowl otic placode in the wallboard rear end side, so that scraper bowl is hinged on the bucket arm.Existing this scraper bowl with crowd shovel structure, pretend industry although can shovel preferably, but can't break ground to the native stone of tunnel vault position or higher range and pull out and take off excavation, have to increase the mobile number of times of excavator during excavation, perhaps explosion number of times, not only increased the running cost of manpower and machinery, and prolonged the construction period, increase construction risk.
The utility model content
For the existing above-mentioned deficiency of prior art, technical problem to be solved in the utility model provides a kind of tunnel excavator scraper bowl, and it can not only shovel native stone and dig, and can pull out the native stone of tunnel vault and higher part position and take off digging operation.
In order to solve the problems of the technologies described above, tunnel excavator scraper bowl of the present utility model, comprise scraper bowl wallboard and scraper bowl side plate, this scraper bowl wallboard is welded to each other into bucket-shaped structure with the scraper bowl side plate, lower front end at the scraper bowl wallboard is fixedly installed bucket tooth, also be welded with tooth plate in the upper end of described scraper bowl wallboard, be provided with the grilled teeth of dialling that leans forward on this on the tooth plate.
After adopting said structure, owing to be welded with tooth plate at scraper bowl wallboard upper end position, should be provided with the grilled teeth of dialling that leans forward on the upper tooth plate, excavator is when construction operation like this, just can use tooth plate and dial grilled teeth and the native stone of the native stone of construction the place ahead higher range or tunnel vault position is dialled taken off excavation, thereby effectively increase the construction operation scope of excavator, reduced construction cost, increased working security.Also owing to be fixedly installed simultaneously bucket tooth at the two ends of scraper bowl wallboard and dialled grilled teeth, make scraper bowl have excavation, dial the several functions of taking off and loading, improved the compliance of excavator constructing tunnel, make the excavation function carry out multiple constructing tunnel operation, thereby improved tunnel machine level of operation and operating efficiency, accelerated construction speed.
Preferably; Described upper tooth plate is welded in the lateral surface of scraper bowl wallboard upper end.This reasonable in design, be convenient to make to use.
Preferably; The lateral surface compartment of terrain of described scraper bowl wallboard is welded with outer stiffening plate, and this outer stiffening plate is the strip plate of arranging along the outside width of bucket direction.The medial surface compartment of terrain of described scraper bowl wallboard is welded with the inboard stiffener that is the strip plate.This structure has not only improved the strength and stiffness of scraper bowl, and can effectively prolong the application life of scraper bowl.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model tunnel excavator scraper bowl is described in further detail.
Fig. 1 is the main TV structure view of a kind of specific embodiment of the utility model tunnel excavator scraper bowl;
Fig. 2 is the left view of structure shown in Figure 1;
Fig. 3 is the top view of structure shown in Figure 1;
Fig. 4 is the upper toothed plate structure view in the structure shown in Figure 1.
Among the figure, 1-scraper bowl wallboard, 2-outer stiffening plate, 3-inboard stiffener, 5-upper tooth plate, 6-scraper bowl side plate, 7-bucket tooth, 8-group grilled teeth.
The specific embodiment
In tunnel excavator scraper bowl shown in Figure 1, the scraper bowl wallboard 1 of this scraper bowl and scraper bowl side plate 6 form the scraper bowl of bucket shape structure by welding; Scraper bowl wallboard 1 bilateral symmetry of curved structure be welded with scraper bowl side plate 6.Be connected with bucket tooth 7 towards the place ahead in the lower front end position of scraper bowl wallboard 1 by toothholder plate.Then be welded with tooth plate 5 above the scraper bowl wallboard 1, be fixedly installed group grilled teeth 8 that leans forward on this on the tooth plate 5, tooth plate 5 is welded on the lateral surface of scraper bowl wallboard upper-end part of driving on this.On the bottom outside face of scraper bowl wallboard 1, be welded with interval outer stiffening plate 2; the strip plate that this outer stiffening plate 2 is arranged for broad ways; this strip plate not only effectively increases scraper bowl intensity, and has protected the scraper bowl wallboard not to be worn, and has prolonged scraper bowl application life.Medial surface at scraper bowl wallboard 1 is welded with the inboard stiffener 3 that is the strip plated construction equally with interval, and this inboard stiffener 3 arranges that along the arc length direction of wallboard this structure can strengthen scraper bowl rigidity, can make things convenient for again the loading and unloading material of scraper bowl.
More than show and described basic principle and essential characteristic and the characteristics of the present utility model of utility model, that describes in above-mentioned fact Example and the manual just illustrates principle of the present utility model, under the prerequisite that does not break away from these practical spirit and scope, the utility model also has various changes and modifications.These variations all fall in the claimed utility model, and the scope of this real requirement protection is defined by claims and equivalent thereof.
