Abstract
The invention relates to an auxiliary side traveling mechanism, in particular to an auxiliary side travelling mechanism for increasing the traction of a tunnelling machine. The auxiliary side traveling mechanism solves the problems that the traction and the machine stability of the tunnelling machine are insufficient, and the like in the process of tunnelling a tunnel with heavy gradient. The mechanism is provided with an auxiliary side traveling part and a connecting buffering device, wherein the auxiliary side traveling part is fixed on the connecting buffering device and is fixedly connected with the tunnelling machine by the connecting buffering device. When the tunnelling machine works in the tunnel with heavy gradient, the traveling part can not provide sufficient traction so that the tunnelling machine can not work in the tunnel with heavy gradient, and at the moment, the auxiliary side traveling mechanism is needed to provide the traction to enable the tunnelling machine to complete the tunnelling work in the tunnel with heavy gradient. When the tunnelling machine tunnels the tunnel with heavy gradient, the traveling mechanism of the side can be adhered to the side wall ofthe tunnel so that the tunnelling machine obtains sufficient traction and good machine stability, thereby greatly improving the tunnelling efficiency and satisfying the requirements of the tunnellingmachine in the process of heavy gradient tunnelling.

Technical scheme of the present invention is:
A kind of auxiliary side traveling mechanism of tunnelling machine, this mechanism is provided with secondary side running part and connection cushioning device, and the secondary side running part is fixed on the connection cushioning device, and the secondary side running part is fixedly connected on the development machine through connection cushioning device.
Described auxiliary side traveling mechanism of tunnelling machine is arranged in the development machine both sides.
The present invention provides development machine secondary side walking mechanism, and this secondary side walking mechanism is fixedly connected on the development machine.On the sidewall attached to the tunnel during this secondary side walking mechanism work, make the secondary side running part produce certain pressure, increased the tractive force of development machine complete machine through the driving force of secondary side walking mechanism the tunnel sidewall 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 secondary side walking 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 secondary side running 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; Secondary side walking mechanism of the present invention is arranged in development machine 3 both sides; Be made up of secondary side running part 1 and connection cushioning device 2, secondary side running part 1 is fixed on the connection cushioning device 2, and secondary side running 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 secondary side running part 1 on the development machine 3, and can make secondary side running part 1 stretch out the sidewall attached to the tunnel, also can be so that secondary side running part 1 is recovered to the both sides of development machine 3.
Secondary side walking mechanism of the present invention makes the secondary side walking mechanism produce certain pressure attached to the tunnel sidewall and to the tunnel sidewall through the action of connection cushioning device 2, increases the tractive force of development machine 3 complete machines through the driving force of secondary side walking mechanism.
As shown in Figure 3, the secondary side running part structure in the embodiment of the invention can be following:
Secondary side running 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 secondary side running part 1 work, produce driving forces by CD-ROM drive motor 4, make secondary side running 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 secondary side running 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 secondary side running part 1 that can make of oil cylinder 9 obtains different adhesive power with sidewall, and can make secondary side running part 1 be recovered to development machine 3 both sides, avoids increasing machine-wide.
The present invention is applicable to the secondary side walking 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 the secondary side walking mechanism to provide tractive force to make development machine accomplish the headwork in heavy grade tunnel.Be specially: the secondary side walking mechanism is fixedly connected on the development machine.When development machine when carrying out the heavy grade tunnelling; Can this skidding be walked the sidewall that mechanism is attached to the tunnel; Pass to the enough adhesive power of secondary side running part by connection cushioning device; Start the walking mechanism and the secondary side running part of development machine then simultaneously, thereby make development machine obtain enough tractive force.Because the secondary side running part is fixedly connected on the development machine through connection cushioning device; Thereby the vibrations of development machine have been reduced; Make development machine obtain good mechanical stability against short circuit; Make development machine obtain enough tractive force and good mechanical stability against short circuit, satisfy development machine requirement when the heavy grade tunnelling.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 heavy grade tunnelling process, can increase substantially drivage efficiency.
