Abstract
The invention discloses a tunneling machine body and shovel plate connecting device. The tunneling machine body and shovel plate connecting device comprises a body and a shovel plate machine which are connected through an engaging lug, the engaging lug is fixedly connected with the body and provided with two lugs; the inside of the connecting lug is provided with a flitch, a reinforced plate and a rib plate, and the flitch is clung to one side of the inside wall of the engaging lug and abutts against the front outside of the body; the reinforced plate is fixedly connected between two lugs of the engaging lug and form a closed cavity structure with the flitch; the rib plate is arranged in the middle of the cavity to divide the cavity into two cavities. Through the adoption of the closed cavity structure formed by the flitch, the reinforced plate and the rib plate and having a simple structure, the phenomenon of serious deformation and fracturing in the prior art is effectively solved, the engaging lug strength is high, the rigidity is high, the manufacturing and maintenance are convenient, the production efficiency is high, and the device has the characteristic of being simple in structure.
Description
Technical field
The invention belongs to a kind of Coal Mechanical structure, the development machine body of more particularly to a kind of high intensity and shovel board connection dress
Put.
Background technology
Development machine is the machine for digging straight underground passage, is provided with shovel board on development machine, the body of development machine and
Shovel board is by the connection of two engaging lugs, and development machine is during underground work, the body of development machine and the engaging lug of shovel board by
In the pulling force by shovel board and fatigue stress, when causing gug, engaging lug stress is excessive causes gross distortion to distort, and can also send out
Raw fracture, intensity and rigid wretched insufficiency, damage frequent, cause production efficiency to decline, labour intensity increase.
The content of the invention
The technical problem to be solved in the present invention is：A kind of development machine body and shovel board attachment means are provided, simple structure, by force
Degree is high, and rigidity is good, is easy to manufacture and safeguards, production efficiency is high, to overcome the shortcomings of prior art problem.
The technical scheme that the present invention takes is：Development machine body and shovel board attachment means, including body and shovel board machine, body
It is connected by engaging lug with shovel board machine, the engaging lug is fixedly connected on body, is provided with two ears, in the engaging lug
Side is provided with pasting board, securing plate and gusset, and the pasting board is close to engaging lug madial wall outside before body, described to add
Gu plate is fixedly connected between two ear of engaging lug, closed cavity structure is formed with pasting board, the gusset is arranged in cavity middle
Position, is divided into two cavitys.
The pasting board arranges two pieces, is symmetrically arranged on two ear madial wall of engaging lug, can balance engaging lug both sides
Stress, producing balanced forces improve integral rigidity and intensity.
The securing plate has three blocks of plates to constitute, and forms closed cavity with pasting board and body front end outer side face, material-saving and
Cost, is easy to manufacture and safeguards.
The pasting board, securing plate and gusset are connected using welding manner, are simple to manufacture conveniently, and operation and maintenance is convenient, into
This is low.
Beneficial effects of the present invention：Compared with prior art, the present invention adopts pasting board, securing plate and the gusset of simple structure
The phenomenon of the closed cavity structure of formation, the gross distortion occurred in efficiently solving prior art and fracture, realizes connection
Ear intensity is high, and rigidity is good, is easy to manufacture and safeguards, production efficiency is high, and the characteristics of there is simple structure.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the junction generalized section of the present invention.
In figure：1st, body；2nd, engaging lug；3rd, pasting board；4th, securing plate；5th, gusset.
Specific embodiment
As shown in Figure 1 and 2, development machine body and shovel board attachment means, including body and shovel board machine, body is led to shovel board machine
Cross engaging lug 2 to connect, the engaging lug 2 is fixedly connected on body 1, be provided with two ears, arrange on the inside of the engaging lug 2
There are pasting board 3, securing plate 4 and gusset 5, the pasting board 3 is close to 2 madial wall of engaging lug outside before body 1, described to add
Gu plate 4 is fixedly connected between 2 liang of ears of engaging lug, closed cavity structure is formed with pasting board 3, the gusset 5 is arranged in cavity
Centre position, is divided into two cavitys, the closed cavity structure formed using the pasting board of simple structure, securing plate and gusset, effectively
The gross distortion occurred in solving prior art and the phenomenon of fracture, realize engaging lug intensity height, and rigidity is good, is easy to manufacture
And maintenance, production efficiency is high, and the characteristics of there is simple structure.
The pasting board 3 arranges two pieces, is symmetrically arranged on 2 liang of ear madial walls of engaging lug, can balance 2 liang of engaging lug
The stress of side, producing balanced forces improve the integral rigidity and intensity of engaging lug 2.
The securing plate 4 has three blocks of plates to constitute, and forms closed cavity, material-saving with pasting board 3 and 1 front end outer side face of body
And cost, it is easy to manufacture and safeguards.
The pasting board 3, securing plate 4 and gusset 5 are connected using welding manner, are simple to manufacture conveniently, and operation and maintenance is convenient,
Low cost.
Find out the correct position of pasting board, securing plate and gusset during welding first by line, by welding pasting board, reinforcing
Plate and gusset are welded on the inside of engaging lug, and weld seam is welded using continuous weld.
