In some embodiments, as shown in fig. 2, the first lifting mechanism 2 may include a first lifting rod 21, a support rod 22, a pulley 23, a chain 24, and a hydraulic system 25. The first end of the first lifting rod 21 is fixedly connected with the first side wall of the tunnel frame 1, the second end of the first lifting rod 21 is fixedly connected with the support rod 22, the first lifting rod 21 is further connected with a hydraulic system 25, the hydraulic system 25 can enable the first lifting rod 21 to extend or shorten to adjust the height of the support rod 22, and the hydraulic system 25 can limit the length of the first lifting rod 21.

Of course, the first connecting rod 41 and the second connecting rod 43 may be both L-shaped rods, and in this case, the first end of the first connecting rod 41 and the first end of the second connecting rod 43 are both fixedly connected to the side surface of the first bracket 11.

In some embodiments, the second end of the first connecting rod 41 and the second end of the second connecting rod 43 are both provided with a groove along the length direction of the tunnel frame 1, and bearings are respectively arranged in the grooves along the width direction of the tunnel frame 1, in this case, the first rotating wheel 42 is connected with the bearing arranged at the second end of the first connecting rod 41, and the second rotating wheel 44 is connected with the bearing arranged at the second end of the second connecting rod 43, so as to ensure that the first rotating wheel 42 and the second rotating wheel 44 can rotate freely.

Thus, after the motor 46 is started, the first runner 42 and/or the second runner 44 can be driven to rotate, and the track 45 sleeved on the first runner 42 and the second runner 44 can be driven to rotate synchronously, so as to drive the movement of the tunnel frame 1.

Wherein, the inner ring of the caterpillar 45 can be engaged with the first runner 42 and the second runner 44, and the outer ring of the caterpillar 45 can be provided with a tooth point with a ground gripping capability, so as to drive the movement of the tunnel frame 1 in the tunnel with a certain inclination, thereby avoiding the slipping phenomenon.

In order to ensure the stability between the first rotating wheel 42 and the second rotating wheel 44 when the tunnel frame 1 is moved by the first moving mechanism 4, as shown in fig. 2, the first moving mechanism 4 may further include a limiting rod 47, and two ends of the limiting rod 47 are respectively connected to the first rotating wheel 42 and the second rotating wheel 44. Of course, both ends of the limiting rod 47 can also be fixedly connected with the first connecting rod 41 and the second connecting rod 43 respectively.

In this way, the first roller 42 and the second roller 44 can be defined as a whole by the limiting rod 47, thereby reducing the possibility of the distance between the first roller 42 and the second roller 44 changing.

Further, the first transfer mechanism 4 may further include a controller electrically connected to the motor 46, and the controller is configured to control the start or stop of the motor 46. Therefore, under the action of the controller, the field control and the remote control can be carried out, so that the operation of operators is facilitated.

It should be noted that the controller included in the first transfer mechanism 4 and the controller included in the hydraulic system 25 may be the same controller, or may be different controllers, and this is not limited in this embodiment of the present application.

It should be further noted that the structure of the second transportation mechanism 5 may be the same as or similar to the structure of the first transportation mechanism 4 described above, and details of this embodiment are not repeated herein. Of course, the structure of the second transportation mechanism 5 may also be different from the structure of the first transportation mechanism 4 as long as the second transportation mechanism can drive the tunnel frame 1 to move, and this embodiment of the present application does not limit this.

In this way, the first transporting mechanism 4 can be independently controlled to drive the tunnel frame 1 to transport, so as to control the tunnel frame 1 to adjust the direction towards the direction deviated from the second transporting mechanism 5; or the second transporting mechanism 5 is independently controlled to drive the tunnel frame 1 to transport so as to control the tunnel frame 1 to adjust the direction towards the direction deviated from the first transporting mechanism 4; or the colleagues control the first transporting mechanism 4 and the second transporting mechanism 5 to drive the tunnel frame 1 to transport so as to control the tunnel frame 1 to transport along the length direction.

In some embodiments, as shown in fig. 3, the pipe pairing apparatus may further include an operation table 6, and the operation table 6 is connected to each of the first side wall and/or the second side wall of the tunnel frame 1. Thus, when the field operation is needed, the operator can stand on the operation table 6 to operate, and the problem that the operator stands at a position difficultly is avoided.

The first side wall and/or the second side wall of the tunnel frame 1 may be connected with the console 6 in a hinged manner, that is, the first support 11 and/or the second support 12 may be connected with the console 6 in a hinged manner. In this way, the operator station 6 can be rotated by the operator station 6 about the connection position with the tunnel frame 1 to effect the retraction or lowering of the operator station 6.

It should be noted that, the operation panel 6 may be provided with a hook so as to be convenient for being connected with the tunnel frame 1 through the hook to realize being packed up, and in addition, the side wall of the tunnel frame 1 may also be provided with a limit table so as to be convenient for being limited through the limit table, so as to ensure that the operation panel 6 is placed along the horizontal plane. Wherein, the lower edge of operation panel 6 can be hugged closely to spacing platform, and with tunnel frame 1's lateral wall fixed connection.

In the embodiment of the application, at the supporting role of tunnel frame, can hoist oil gas pipe through first elevating system and second elevating system to the adjustment of the height of oil gas pipe is carried out at pipeline group's in-process to the realization, the operating personnel only need carry out simple swing to oil gas pipe this moment, can realize orificial well being, has improved pipeline group's efficiency, has reduced operating personnel's work load. In addition, when the tunnel frame is driven to move under the action of the first moving mechanism and the second moving mechanism, the tunnel frame can be moved, and the direction of the tunnel frame can be adjusted, so that the hoisted oil and gas pipe can be more conveniently moved to a position where pipe orifice assembly is needed, the process of laying a track in a tunnel is avoided, and the pipe orifice assembly efficiency is improved.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
