SU100422A1 - Device for feeding a perforator when drilling vertical holes - Google Patents

Description

The invention relates to a device for feeding a perforator when drilling vertical holes using two parallel pneumatic cylinders.

This device is more perfect in comparison with the known ones, since it provides a significant increase in the depth of drilling of the hole without the labor and time spent on rearranging and replacing the H1Tang OR drill.

This is achieved by the fact that the perforator and the cylinders are mutually movable relative to each other. The perforator, together with the cylinders, is raised by pushing the rods out of the cylinders to the FULL stroke of the piston, which is the first stage of the feed. In the second stage, a rod stand is installed between the bar, connecting the ends of the cylinders, and the perforator, which allows for further feed of the perforator by means of a new extension of the stems.

FIG. 1 is a schematic diagram of the proposed device; in fig. 2, 3 and 4 scheme of his work in drilling vertical HjnypOB.

The device consists of two parallel pneumatic cylinders /, between which there is a perforator 2, and a rod stand 3.

The cylinders / are connected by a tube 4, which serves simultaneously as a skarnit piece, a handle for carrying and holding the device in the required position during operation, and an air duct for the entry of compressed air into the cylinders /. At the bottom, they are connected to each other by means of a strap 5. One cylinder has a valve 6 for lowering compressed air from the cylinders.

The proposed device operates as follows.

The first stage of supplying the perforator 2 is carried out by lifting it together with the cylinders / by extending the rods from the SILS of wood for the FULL stroke of the piston (Fig. 2). Thereafter, between the strap 5 and the perforator 2, an anvil support rod 3 is inserted and the cylinders are placed on the rods, moving them relative to the fixed perforator (Fig. 3).

The second stage of the punch feed is accomplished by a new

extending the UJTOKOB from the cylinders. (FIG. 4). In this case, the lower end. the supports 3 abut their protrusions against the strip 5, connecting the cylinders.

Subject N o d e b e

A device for feeding a perforator and drilling vertical holes using two parallel pneumatic cylinders, characterized in that, in order to drill the hole at full depth without shifting and replacing the rods and drills, the perforator and cylinders are mutually movable relative to each other so that after lifting punch together with the cylinders, by pushing the rods out of the cylinders to the full stroke of the piston, which is the first stage of the supply, set between the bar connecting the ends of the rods and the perforator, st A stainless stand and deposit the cylinders on the rods, linking the latter with the stand, followed by a new extension of the rods to implement the second stage of the punch feed.
