Definitions
- the invention relates to a ram boring machine connected via a hose to a compressed air source and having an impact piston axially displaceable in a tubular housing and alternately pressurized with compressed air.
- Such ram boring machines are primarily used to lay supply lines for water or electricity, as well as telephone cables, without having to tear up the pavement or sidewalks and dig a trench. They usually have a percussion tip which is actuated by a pneumatically operated percussion piston. In order to advance the percussion tip, the percussion piston is moved back and forth in a tubular housing in that compressed air supplied via a compressed air line alternately acts on the front and rear end faces of the percussion piston.
- shut-off valves e.g. ball valves
- the invention has for its object to provide a starting device for ram boring machines, which is effective even the longer compressed air hoses, so that they can start up without difficulty.
- this object is achieved by a valve which is arranged upstream of the percussion piston and opens suddenly at a predetermined pressure.
- This valve should be arranged as close as possible to the percussion piston and can therefore be arranged either in the housing of the device itself or in the hose between the device and the compressed air source close to the device.
- Such a valve can be controlled either by compressed air, by hydraulic pressure or by gas pressure.
- a prerequisite for its effectiveness is that a sufficiently high pressure builds up in front of the valve so that when the valve is suddenly opened, a pressure surge acts on the percussion piston in the implement, which immediately sets the working piston in motion.
- the valve preferably has a control piston which can be moved and sealed in a housing and which has differently sized hydraulic, gas or compressed air piston surfaces in the closed and in the open state.
- control piston In order to ensure that the valve opens suddenly at a predetermined pressure, the control piston is held in the direction of the closed position by means of a spring.
- a tubular stepped piston which is guided in a sealed manner in the housing, is closed at one end, guided in a sealed manner in the region in this area and has radial passage openings; it is provided at the other end with a piston part of larger diameter which is also sealed in the housing.
- a ram boring machine 16 is connected via a compressed air hose 17 to a compressed air source, not shown.
- a start valve 18 is arranged in the compressed air hose 17 close to the ram boring machine 16. This start valve 18 should be arranged as close as possible to the ram boring machine 16, so that the pressure wave reaches the percussion piston in the ram boring machine 16 as undamped as possible after opening the start valve 18.
- the start valve 18 can therefore also be arranged both directly on the ram boring machine 16 and in the ram boring machine 16 itself.
- the start valve 18 consists of a cylindrical housing 2, which is closed at one end by means of a valve plug.
- a tubular piston 3 is arranged in the housing 2 and is surrounded by a compression spring 5 arranged in an annular space 4 of the housing 2.
- the end of the valve plug 1 facing the housing interior forms a stop surface 7.
- the housing 2 has a shoulder 8, which also serves as a stop.
- the tubular piston 3 is guided with its one end sealed in a bore 9, so that no compressed air can escape from radial passage openings 10 arranged in this area in the tubular piston 3. For this reason, the tubular piston 3 also has a closed end 15.
- piston part 14 At the other end of the tubular piston 3 there is a piston part 14 of larger diameter, one end face 11 of which, in the position shown in FIG. 2, bears tightly against the stop surface 7 of the valve plug 1. With its opposite side 12, the piston part 14 comes to rest against a shoulder 8 in the housing 2 when it moves as in FIG. 3 under the influence of the compressed air.
- the compressed air supplied via the hose connection 6 acts only on the inner surface of the tubular piston 3.
- the air pressure rises, so that the pressure on the tubular one Piston 3 acting force exceeds the opposing force of the compression spring 5, the tubular piston 3 moves, so that the rear end 11 of the piston part 14 of larger diameter lifts from the stop surface 7.
- the air pressure acts not only on the inner surface of the tubular piston 3, but also on the end face 11 of the piston part 14. Since the force acting on the tubular piston 3 and the piston part 14 is now considerably greater than the force of the compression spring 5, the tubular piston 3 moves suddenly with the piston part 14 into the position shown in FIG. 3.
- the radial passage openings 10 pass from the area of the bore 9 into the area of the air duct 13, and the pressure wave which thereby develops hits the percussion piston of the ram drilling device 16 without noticeable damping, which sets in motion immediately, without the risk of standstill there is a dead center position.
