Description

The invention relates to machines for tunneling, with mounting sites for auxiliary works, mainly for the construction of elements of the prefabricated lining.

The purpose of the invention is to increase the convenience of work.

In FIG. 1 shows an installation site at different angles of inclination of the boom, side view; in FIG. 2 - the same, with the horizontal position of the boom; in FIG. 3 - the same, top view.

The mounting platform of the tubing spreader consists of a frame 1, rigidly fixed to the frame of the tiered steps 2 and the guard 3. The frame 1 is mounted on the pipe 4, through which the axis 5 is inserted, inserted into the hole in the boom 6. An arm 7 with a hole is fixed to the pipe 4 a link is pivotally connected, consisting of two links 8 and 9, interconnected by a hinge 10. Link 9 of the link is pivotally attached to the support base 11 of the boom 6. The arrow 6 is fixed to the support base 11 with the possibility of rotation in the vertical plane by the hinge 12. Thus the base, the boom body 6, the rods from the links 8 and 9, the bracket 7 and the support base part between the hinge 12 and the fastening point of the link 9 with the support base form a hinged parallelogram to maintain the frame 1 with steps 2 in working position. The support base 11 has a stop 13 made in the form of a plate and fixed with the possibility of rotation and fixing the position by a latch in the form of a pin 14, fixed in the supporting base 11. The stop 13 is placed on the supporting base 11 so that when the boom is tilted relative to the horizontal by an angle of 25-30 °, l the possibility of its interaction with link 9 thrust.

For work at the roof of the excavation, the boom 6 is turned upward relative to the hinge 12 so that the mounted support element, for example tubing, is located at the roof of the excavation. At the same time, its installation and fastening with other tubings is carried out from the upper steps of 2 mounting sites, the location of which provides the worker with the opportunity to stand without bending. When installing the side tubing located below, lower the boom 6, the steps 2 maintain a horizontal position due to the parallelogram mechanism in which the traction from the links 8 and 9, working in tension, is stretched in one line.

When the tubing is captured by the boom 6 from the trolley 16 or any other land vehicle, the boom 6 is lowered to a horizontal position. In this case, when the boom 6 is tilted relative to the horizontal by an angle of 25-30 ° in the stop position 13 shown in FIG. 1 and 2, the link 9 of the rod comes into contact with the stop 13. Lowering the boom 6 down does not change the position of the link 9 of the rod, and the link 8 of the rod rotates relative to the hinge 10, while the bracket 7 rotates together with the frame 1 relative to the arrow 6, i.e. . the entire mounting pad is rotated in a vertical plane with its rise relative to the lower edge of the boom 6. In this position of the mounting pad, the boom 6 can be freely installed in the immediate vicinity of the body of the trolley 15, which makes it possible to grab the tubing from the trolley using a tow hitch. In the same position of the installation site, it becomes possible to carry out other technological operations with arrow 6 in the immediate vicinity of the excavation soil. If necessary, the emphasis 13 can be turned down, i.e. to the position when it does not interact with the link 9 of the traction, and the steps 2 of the mounting platform retain their working (horizontal) position when lowering the boom until the platform touches the soil.

Claims (2)

  1. The invention relates to mining machines that have mounting platforms for auxiliary operations, mainly for erecting lining elements. The purpose of the invention is to improve the convenience of work. FIG. I shows the mounting pad at different angles of the boom, side view; in fig. 2 - the same, with a horizontal boom; in fig. 3 - the same, top view. The mounting platform of the pipe laying machine consists of a frame 1 rigidly fixed on the frame of brown steps 2 and a barrier 3. The frame 1 is fixed on the pipe 4, through which the axis 5 is passed, inserted into the hole in the boom 6. The pipe 7 is fixed to the bracket 7 with the hole to which A hinge joint, consisting of two links 8 and 9, interconnected by a hinge 10. A link of 9 tons of hinge is hingedly attached to the support base 11 of the boom 6. The boom 6 is fixed on the support base I1 and can be rotated in a vertical plane with the help of a hinge 12. Taki , the boom body 6, the thrust of the links 8 and 9, the bracket 7 and a base portion of the support between the hinge point 12 and fixing unit 9 to the support base form a hinged parallelogram to maintain in working position the frame 1 with stages E
  2. 2. The support base 11 and. Has a stop 13, made in the form of a plate and fixed with the possibility of rotation and fixation of the position of the retainer in the form of a pin 14, fixed in the support base 11. The stop 13 is placed on the support base 11 so that when the boom is tilted relative to the horizontal at an angle of 25-30 °, it was possible to interact with the 9-ti link. In order to carry out work at the roof of the excavation, the boom 6 is turned upwards relative to the hinge 12 so that the mounting element, such as tubing, is mounted at the roof of the excavation. At the same time, its mounting and fastening with other tubings is carried out from the upper steps 2 of the assembly site, the location of which provides the worker with the opportunity to stand without being bent. When mounting the side tubings located below, the boom 6 is lowered, the steps 2 remain horizontal position due to the parallelogram mechanism, in which the pull from links 8 and 9, working in tension, is stretched in one line. When seizing the tubing by the boom 6 from the trolley 16 or any other ground vehicle, the boom 6 is lowered to a horizontal position. Moreover, when the boom 6 is inclined relative to the horizontal at an angle of 25-30 ° in the position of the stop 13 shown in FIG. 1 and 2, the 9 ti link comes into contact with the anvil 13. Lowering the boom 6 downwards does not change the position of the 9 ti link, and the 8 ti link rotates relative to the hinge 10, while the brackets 7 rotate with the frame 1 relative to the boom 6 i.e. The entire assembly platform is rotated in a vertical plane with its elevation relative to the lower edge of the boom 6. In this position of the assembly site, the boom 6 can be freely installed in the immediate vicinity of the body of the trolley 15, which makes it possible to grab the tubing from the trolley by means of a hitch. In the same position of the installation site, it is possible for the boom 6 to perform other technological operations in the immediate vicinity of the production soil. If necessary, the stop 13 can be turned down, i.e. to the position where it does not interact with the link of 9 tons, and the steps 2 of the assembly site retain their working (horizontal) position when lowering the boom until the platform touches the ground. Claims The mounting platform of the tubing blocker, comprising a frame pivotally connected to a vertical pivot boom mounted on a support base, and held in working position by a parallelogram mechanism, the rod of which is pivotally connected to the support base and the frame bracket, characterized in that the purpose of improving the convenience of work, ha ha is made of two links hinged together among themselves, and the support base has a swivel support with a lock that interacts with one it is one of the links ti gi when lowering the boom.
