Description

Track mounting rack, pipeline extension device and heading machine

Technical Field

The utility model relates to the technical field of suspension devices for pipes or the like in mines or tracks, in particular to a track mounting frame, a pipeline extension device and a heading machine.

Background

At present, most of tunnel or underground engineering is constructed by adopting shield/TBM. When the tunneling distance is short, the tunneling route is complex, the transition times are many and the requirement of rapid disassembly and assembly of the machine is met, the prior art usually separates the rear support of the shield/TBM from the host machine, integrally arranges the rear support equipment outside the tunnel, and only enters the tunnel for tunneling. The tunneling mode has the advantages that the disassembly and assembly machine and the transition are rapid and convenient, and the tunneling mode has the defect that along with the continuous tunneling of the main machine, the distance between the main machine and the rear support is continuously increased, so that much inconvenience is brought to the pipeline connection and extension between the rear support and the main machine.

In order to solve the problem of connection and extension of the pipeline, a patent with an authorization publication number of CN206554975U provides a pipeline hanging device, which includes a fixed base fixed on the top of the tunnel through an anchor rod and a track in accordance with the extending direction of the tunnel, the track is hoisted below the track through a connecting anchor chain, a hanging line pulley for fixing the pipeline is installed on the track in a guiding and moving manner, and the host drives the hanging line pulley to slide along the track when heading forward, so as to extend the pipeline. The pipeline hanging device has the following two problems: firstly, the rail is hoisted at the top of the tunnel through the fixed base, so that the main space occupied by the tunnel is large, and the rail is easy to interfere with other equipment in the tunnel when in use; and secondly, the connection anchor chain is of a flexible connection structure, the host drives the wire hanging pulley to move and simultaneously drives the track to deflect in the moving direction of the host, so that the track cannot be always kept horizontal, and when the wire hanging pulley is subjected to traction force in the horizontal direction of the host, the movement direction between the wire hanging pulley and the track is inconsistent, so that clamping stagnation is generated, the pipeline is not smoothly extended, and the tunneling efficiency is influenced.

In addition, a patent with publication number CN202560321U provides a synchronous moving device for a split shield starting pipeline, which can also be used to solve the above-mentioned problems of connecting and extending the pipeline, and the moving device includes a lifting lug fixed on the side wall of the tunnel, and a track is connected to the lifting lug by hoisting a rope. In addition, a pipeline bracket is provided in patent publication No. CN211342917U, which includes a pulling member connected to the side wall of the tunnel, a rail hinged to the lower end of the pulling member, and a supporting frame, one end of which is supported on the wall of the tunnel, and the other end of which is connected to the rail, so that the rail is kept horizontal. But because tunnel wall unevenness and bear during heavier when pipeline and cable on the track, the support frame often can't guarantee stable support for the track is very difficult to keep the level, and like this, the sliding part takes place the eccentric wear even jamming easily when sliding on the track. In terms of installation of pipelines, the devices provided in the three aforementioned patents fix the pipeline and the cable together through the pipe clamp, but the cable is heavy and fixed on the pipe clamp together, so that the work intensity is high, and the problems of time and labor waste exist.

Specifically, as shown in fig. 4, the rail mounting bracket 400 includes a rail mounting body, the rail mounting body is a cross beam 401, the cross beam 401 is horizontally disposed in the tunnel 700 and perpendicular to the extending direction of the tunnel 700, one end of the cross beam 401 close to the tunnel wall of the tunnel 700 is connected to the tunnel wall through a connecting seat 403, the cross beam 401 is hinged to the connecting seat 403 through a first hinge shaft 402, and in order to prevent the cross beam 401 from having a deflection degree of freedom in the extending direction of the tunnel 700, the axial direction of the first hinge shaft 402 is consistent with the extending direction of the tunnel 700. One end of the crossbeam 401, which is far away from the hole wall, is connected to the hole wall through a leveling connection mechanism, the leveling connection mechanism comprises a traction piece 404 and a connecting piece 411, one end of the traction piece 404 is hinged to the crossbeam 401 through a second hinge shaft 405, the other end of the traction piece 404 is hinged to the connecting piece 411 through a third hinge shaft 406, and the connecting piece 411 is connected to the hole wall through an anchor bolt.

Meanwhile, the position of the connecting piece 411 does not need to be set deliberately, and when the track mounting frames 400 are not at the same height, the connecting piece can be adjusted by the length adjusting mechanism, so that the position of the connecting piece is prevented from being adjusted repeatedly, and the work efficiency is improved while the workload is reduced. The corresponding positions on the rail 500 are respectively connected with the cross beams 401 on the rail mounts 400, and the connection manner between the rail 500 and the rail mounts 400 is the same, and only one of the connection manners is taken as an example to explain the connection manner: as shown in fig. 2 and 4, the lower side of the cross beam 401 is provided with two L-shaped connecting blocks 410, vertical portions of the two connecting blocks 410 are welded to the lower side of the cross beam 401, and horizontal portions of the two connecting blocks 410 extend toward each other with a certain interval.

In addition, the adjacent pipe clamp pulleys 600 are connected through a steel wire rope 605, and the length of the steel wire rope 605 connecting the two pipe clamp pulleys 600 is greater than the length of the pipeline 300 between the two pipe clamp pulleys 600, so that the pipeline 300 does not bear tension when the main machine 100 pulls the pipe clamp pulleys 600, and the pipeline 300 is protected.
