Abstract
The invention relates to an auxiliary top traveling mechanism, in particular to an auxiliary top traveling mechanism which increases the traction of a tunneling machine and solves the problems of the insufficient traction and stability and the like of the tunneling machine during tunneling a steep tunnel. The mechanism is provided with an auxiliary top traveling part and a connection cushioning device, wherein the auxiliary top traveling part is fixed to the connection cushioning device, and the auxiliary top traveling part is fixedly connected on the tunneling machine by the connection cushioning device. When the tunneling machine works in a steep tunnel, since the traveling part can not provide sufficient traction and the tunneling machine can not work in the steep tunnel, the auxiliarytop traveling mechanism is required to provide the traction to enable the tunneling machine to complete the tunneling of the steep tunnel. When the tunneling machine is in the progress of tunneling the steep tunnel, the top traveling mechanism can be attached to the top plate of the tunnel, so that the tunneling machine can obtain the sufficient traction and the favorable stability, thereby greatly raising the tunneling efficiency and meeting the requirements for tunneling a steep tunnel by the tunneling machine.

Summary of the invention
The object of the present invention is to provide a kind of auxiliary top traveling mechanism of tunneling machine; It is the mechanism that increases development machine tractive force; Solve tractive force and the problems such as stable deficiency of machine of development machine in heavy grade shape tunnelling process, this mechanism can increase substantially the stability of drivage efficiency and development machine.
Technical scheme of the present invention is:
A kind of auxiliary top traveling mechanism of tunneling machine, this mechanism is provided with auxiliary top traveling part and connection cushioning device, and auxiliary top traveling part is fixed on the connection cushioning device, and auxiliary top traveling part is fixedly connected on the development machine through connection cushioning device.
The present invention provides the development machine auxiliary top traveling mechanism, and this auxiliary top traveling mechanism is fixedly connected on the development machine.On the top board attached to the tunnel during this auxiliary top traveling mechanism work, make auxiliary top traveling mechanism produce certain pressure, increased the tractive force of development machine complete machine through the driving force of auxiliary top traveling mechanism back through connection cushioning device.
The invention has the beneficial effects as follows:
1, the present invention makes development machine can obtain enough tractive force when the heavy grade tunnelling through auxiliary top traveling mechanism motion.
2, the present invention is through making the stability of development machine complete machine when the heavy grade tunnelling obtain large increase with being fixedly connected of development machine.
3, the present invention through with being fixedly connected of development machine solved development machine when the heavy grade tunnelling because the safety problem that machine glides and causes.

Among the figure, 1 auxiliary top traveling part; 2 connection cushioning device; 3 development machines; 4 CD-ROM drive motors; 5 track frames; 6 creeper tread assemblies; 7 Connection Blocks; 8 linking arms; 9 oil cylinders; 10 running part Connection Blocks.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
Like Fig. 1-shown in Figure 2, auxiliary top traveling mechanism of the present invention is made up of auxiliary top traveling part 1 and connection cushioning device 2, and auxiliary top traveling part 1 is fixed on the connection cushioning device 2, and auxiliary top traveling part 1 is fixedly connected on the development machine 3 through connection cushioning device 2.Among the present invention, connection cushioning device 2 is fixedly connected on auxiliary top traveling part 1 on the development machine 3, and can make auxiliary top traveling part 1 stretch out the top board attached to the tunnel, also can be so that auxiliary top traveling part 1 is recovered to development machine 3 tops.
Auxiliary top traveling mechanism of the present invention makes auxiliary top traveling mechanism be pressed on the back and to back and produces certain pressure through the action of connection cushioning device 2, increases the tractive force of development machine complete machine through the driving force of auxiliary top traveling mechanism.
As shown in Figure 3, the auxiliary top traveling part structure in the embodiment of the invention can be following:
Auxiliary top traveling part 1 can mainly be made up of following three parts: CD-ROM drive motor 4, track frame 5, creeper tread assembly 6, creeper tread assembly 6 are installed on the track frame 5, and CD-ROM drive motor 4 is installed on the sprocket wheel of track frame 5 both sides.During auxiliary top traveling part 1 work, produce driving forces by CD-ROM drive motor 4, make auxiliary top traveling part 1 along the tunnel sidewall advance, be fixedly connected with development machine 3 through connection cushioning device 2, thus the driving force of increase development machine 3.
As shown in Figure 4, the connection cushioning device structure in the embodiment of the invention can be following:
Connection cushioning device 2 can mainly be made up of following four parts: Connection Block 7, linking arm 8, oil cylinder 9, running part Connection Block 10; Connection Block 7 is fixedly connected with development machine 3; Running part Connection Block 10 is fixedly connected with auxiliary top traveling part 1; Linking arm 8 one ends and Connection Block 7 are hinged, and linking arm 8 other ends are connected with running part Connection Block 10, and oil cylinder 9 two ends are hinged with Connection Block 7 and running part Connection Block 10 respectively.The flexible auxiliary top traveling part 1 that can make of oil cylinder 9 obtains different adhesive power with top board, and can make auxiliary top traveling part 1 be recovered to development machine 3 tops, avoids increasing machine height.
The present invention is applicable to the auxiliary top traveling mechanism of large gradient roadheader; When development machine is worked in tunnel with heavy gradient; Running part can't provide enough adhesive power to make development machine in the heavy grade tunnel, to work, and at this moment just needs auxiliary top traveling mechanism to provide tractive force to make development machine accomplish the headwork in heavy grade tunnel.Be specially: auxiliary top traveling mechanism is fixedly connected on the development machine.When development machine is carrying out heavy grade when driving; Can this auxiliary top traveling mechanism be attached to the top board in tunnel; Pass to the enough adhesive power of auxiliary top traveling part by connection cushioning device; Start the walking mechanism and the auxiliary top traveling part of development machine then simultaneously, thereby make development machine obtain enough tractive force.Because auxiliary top traveling part is fixedly connected on the development machine through connection cushioning device, thereby reduce the vibrations of development machine, made development machine obtain good mechanical stability against short circuit, satisfied development machine requirement when heavy grade tunnels.Adopt the present invention to solve the problem that development machine walking that development machine causes by adhesive power is short of power in the heavy grade tunneling process; Increase stability, safety and the mobility of the complete machine of development machine in the heavy grade tunneling process, can increase substantially drivage efficiency.
