Description

Device for immersing pipes into the ground by driving

The utility model relates to the field of construction equipment and relates to devices for driving a pipe into the ground by driving it and uses it at the 6th floor, with a cushion for laying underground utilities.

From the description to the author's certificate N 607902, a device for immersing a pipe into the ground by driving into a clogging device is known, containing a percussion mechanism, a sleeve mounted on its nose, the inner surface of which is tapered, and ring grooves are made on the end face of the sleeve facing the nose of the shock assembly .The bushing is connected to the clogged pipe and provides shock transmission to it. The disadvantage of this solution is the cantilever attachment of the shock node through the sleeve. This leads to the swing of the hzost part of the device, which increases the load in the sleeve and reduces the transmission coefficient of shock. In addition, the presence of a conical connection of the sleeve with the pipe makes it difficult to disassemble the device after work. Thus, this device has insufficient reliability and reliability.

In the known device according to the author's certificate N 1664980, containing a percussion mechanism, a sleeve, a clip and a clamping device for attaching the sleeve to the pipe, which is made in the form of clamps. Such a design makes it easier to disassemble the device after work, but does not eliminate the presence of cantilever during installation on the pipe, which, as in the analogue, promotes the swing of the tail of the device, causing the possibility of breakage due to the presence of stresses in the sleeve. . . . . . - -.

The technical problem solved by the utility model is to increase the reliability and productivity of the device, as well as ease of maintenance. ,; .

This problem is solved in that the device for immersion

... -. I

pipes into the ground by clogging, containing a percussion mechanism and a sleeve connected to the end of the pipe to be hammered, mounted on the percussion mechanism, provided with medium with axial-axial-fixation of the shock mechanism relative to the blockage, the pipe and its coaxial arrangement E02F 5/18

filled in the form of at least one rod, one end fixed to the pipe to be hammered, and the other to the tail of the percussion mechanism, the fiction of the coaxial arrangement makes it possible: -...-. .

the ability to eliminate the cantilever attachment of the percussion mechanism on the clogged pipe, i.e. improve reliability and performance. . Axial fixation makes it easier to assemble and disassemble the device.

If the connection of the impact mechanism with the sleeve is performed with a taper angle greater than the jamming angle, this will facilitate the removal of the sleeve from the impact mechanism.

The utility model is illustrated in the drawing, which shows the inventive device.

A device for immersion of a pipe into the ground by driving contains a percussion mechanism 1, for example, mon: eumatic, connected

  i- -

with a clogged pipe 2 by means of a transition sleeve 3. A shock mechanism is connected to a clogged pipe by means of a rod 4 attached to the tail of the percussion mechanism. The connection 5 of the impact mechanism .1 with the sleeve 3 can be made conical, and the angle of taper should be greater than the angle of jamming.

When driving pipe 2 into the ground, the percussion mechanism. 1. transfers the shock load through the sleeve 3 to the clogged pipe 2 and makes it sink into the ground. In this case, the axial fixation mechanism of the impact mechanism 1, made in the form of a rod 4, will pull the impact mechanism 1 to the driven pipe 2, fixing them in the axial direction, and hold it from the vertical runout of the impact assembly in the radial direction, thereby protecting the sleeve 3 from bending forces vr increasing Effectiveness of shock transmission to the pipe. After work is complete, the device is easily dismantled: removal of the thrust will allow axial tension to be removed, and due to the conical connection with an angle exceeding the self-jamming angle, sleeve 3 is quite easy to disconnect from the percussion mechanism .1 .. As a result, the device is ready for transportation.
