The German patent application 3819717 introduced by the same applicant of the present invention and the patentee is a kind of continuous (non-stop) track-type track tamping on the track, leveling and track-tracking machine along the working direction. A rack arranged in front and back and supported on the traveling mechanism. The middle frame directly connected with the track tamping machine is equipped with a height-adjustable middle plow and side slope plow arranged between the two traveling mechanisms, and the third frame is equipped with a plow arranged between the two traveling mechanisms. A track stabilizer and a sweeping unit. In addition, each rail is equipped with a height-adjustable and laterally pivotable small moldboard on the protruding front end of the rail tamping machine. With such a continuous walking mechanical combination with a cab at the front and rear ends and a control room at the tamping unit, it is possible to tamp the sleeper at the same cycle as the stepping operation of the tamping unit, and use the same mechanical combination It is also possible to shape the ballast bed and then compact the ballast bed with a track stabilizer. According to another mechanical combination scheme introduced in this patent document, the continuously running track tamping, leveling and track-setting machine is only equipped with a second frame that can be adjusted in height through a driving device at the rear along the working direction. , Ballast plow device with ballast cleaning device. In the case of very uneven accumulation of ballast or less ballast in the tamping area, it is necessary to use this mechanical combination to run once before the tamping operation, use the ballast plow device to shape the ballast bed, or transport the ballast to the tamping area ballast required. This mechanical combination has cabs at the ends of two connected frames, where the height of the machine is the same as the cabs from end to end.

According to U.S. Patent No. 4,165,694 of the same applicant and patentee of the present invention, it has become a known track tamping, leveling and channeling machine that can walk one by one sleepers, the front and rear ends of the track tamping machine are respectively Hinged together with a trailer that has only one running gear. The trailer at the front can be connected to the track tamping machine in a longitudinally telescopic and movable manner through a coupling device, and has a middle plow and a side slope plow whose height can be adjusted by a driving device between the running gears. Above these plows there is a control room and a mechanical structure designed to be at the same height as it. A height-adjustable ballast sweeper and detection mechanism for the reference system are mounted on the rear trailer. Such a mechanical equipment with a tamping machine that can walk step by step and a track bed plow device that can walk continuously or move relative to the tamping machine has never produced so far.

In addition, according to the U.S. Patent 4,165,693 of the same applicant and patentee of the present invention, a similar track tamping, leveling and channeling machine is known in the U.S. Patent 4,165,693. Set on a vehicle that can travel independently and continuously, this vehicle has its own cab and mechanical structure equipped with indicating instruments and control devices.

The object of the present invention is to provide a continuous (non-stop) rail-traveling machine of the type described at the outset for tamping sleepers of a track. Utilize this machinery to be able to tamp sleeper and repair track bed better and more economically, and make machinery have better use possibility.

The present invention is characterized in that, in a continuous (non-stop) rail-traveling machine of the type mentioned at the outset, the rail tamping machine is designed so that it follows the vehicle at the front end of the frame in the direction of work through at least The ends of the second frame supported by a running gear can be connected or linked together by joints.

Using a kind of such mechanical combination according to the present invention, for the first time, the machine can be continuously (non-stop) walked once and can be continuously repaired and formed on the ballast bed, followed by the evenly filled ballast track. Continuous tamping. The use of this set of machinery can be particularly economical, with less manpower and machinery, and after one operation, a track that is evenly tamped and durable due to the evenly filled ballast can be processed. In addition, because the vehicle connected with the ballast plow device is directly hinged with the tamping machine, it is possible to directly manipulate the ballast plow device smoothly, and directly transmit the force of the driving mechanism of the tamping machine to the front The vehicle of the ballast plow so that there is sufficient propulsion to distribute the ballast continuously and without disturbance. Through this combination, this force transmission device, the vehicle with the ballast plow, which is hinged in front of the tamping machine, can be made particularly flat and low in construction. Another special advantage resulting from this is that from the cab at the front of the tamping machine, an unhindered, straight-through line of sight to the front track can be guaranteed, and at the same time, accurate observation and manipulation of the ballast plow device can be guaranteed. The unobstructed view required to use the center plow or the side plow depending on the ballast situation. In addition, due to the advantages of the huge traction and driving force that can be transmitted between the tamping machine and the vehicle equipped with the ballast plow installed in front of it, it is possible to smoothly organize the machinery into trains for rapid transfer of work sites.

A special development of the invention is that the rail tamping is connected to the second frame of the front, with a height-adjustable ballast plow device with a center plow and a side plow controllable by the drive The machine is designed so that the end of the frame at the rear in the working direction can be connected or linked together with the end of a third frame supported by at least one running gear of another vehicle, where The third frame is provided with a set of ballast cleaning device which can be adjusted in height by the driving device and is preferably connected with a set of horizontal conveyor belts controlled by the driving device.

Another excellent expansion scheme of the present invention is: two frames respectively equipped with ballast bed plow device and ballast cleaning device are designed to be only provided with the trailer type vehicle of a traveling mechanism. This trailer-mounted vehicle with ballast plowing device and ballast cleaning device can advantageously transmit force with a particularly simple structure, especially to the vehicle in front or behind the tamping machine, so that there is a sufficiently large push force or traction to distribute or clear ballast continuously and smoothly. In addition, the end of the tamping machine is hinged, so that the continuous walking type tamping machine currently in use can be retrofitted in a simple way.

Another suitable structure of the present invention is: the front, if necessary, the rear frame has a support beam that preferably protrudes in the middle, and these support beams are respectively rammed through a preferably omnidirectional joint. The end of the solid machine is connected with the tamping machine within the scope of the traveling mechanism. Such a method of articulation to the front and sometimes rear frame is simple but robust and ensures a reliable transfer of sufficient force from the tamping machine to the front bed plow unit when the track is well run , in order to continuously distribute the ballast and form the ballast bed without any hindrance.

Another excellent development of the invention is that a vehicle with a second frame at the front with a ballast plow device and a vehicle with a third frame with a ballast cleaning device at the rear is designed as In the scope of being arranged on the driver's cab or the operating room at the front end or the rear end of the track tamping machine, the first frame respectively following the middle can be connected or linked together by a joint, and has a second frame and a third frame respectively. The two vehicles on the frame do not have a cab or a control room, nor do they have a high mechanical structure, and are designed to be basically only slightly higher than the height of the frame of the corresponding running mechanism. This low structural form of the most structurally simple front-mounted vehicle, especially in connection with the adjoining driver's cab or operator's cab on the tamping machine in the middle, allows freedom in the direction of travel of the adjacent tracks. Unobstructed line of sight, while providing a comprehensive, unrestricted view of the front ballast plow unit and the rear ballast clearing unit, allowing these units to be monitored and easily operated.

Finally, another particularly excellent structure of the present invention is: a frame with a self-contained travel drive device and a drive device, a braking device, a power supply device and a control device is housed, and two travel devices separated by a distance The tamping unit between the mechanisms, and a continuous (non-stop) walking track tamping machine arranged along the working direction in front of the tamping unit, is designed to be both track tamping, leveling and setting road machine, and a standard vehicle with buffer couplings at both ends of the frame, at least one of the two vehicles is equipped with buffer couplings at both ends of its frame so that they can be quickly disconnected from each other, or The corresponding end of the frame of the track tamping machine can be quickly disengaged. Such a track tamping, leveling and track machine designed as a standard vehicle is especially suitable for vehicles equipped with other work tools at the end. The vehicle is articulated and will not interfere with various work tools located between the running gear. A buffer coupler is installed at the end of the tamping machine and at the end of the auxiliary frame, which can be quickly connected and disconnected as needed. Although there are vehicles connected at the front and rear, the tamping machine can still be assembled without restriction. Get into trains for quick and safe transfers to work sites.
