Description
Technical Field
The utility model relates to a railway maintenance machinery is equipped, especially relates to a tamping car.
Background
Present large-scale railway maintenance machinery switch tamping car is under the condition of not changing the lane, there is the blind area to the tamping coverage area in switch region, mainly embody in the fourth rail region far away from the thread, consequently switch tamping car will realize then needing to change the lane to the regional full coverage tamping operation of switch, nevertheless receive the construction tissue restriction, switch tamping car often can only carry out the tamping operation in a lane, therefore adopt artifical tamping operation in the switch region that switch tamping car can't cover usually, make switch tamping operation quality relatively poor. In order to improve the tamping quality of the turnout area, it is necessary to develop a tamping vehicle which can complete the high-quality tamping operation of the whole turnout area under the condition of not changing the railway.
Chinese patent No. ZL201580058008.6 discloses a track tamping machine (22) for tamping a ballast bed of a track, which has at least two tamping units (37, 38, 41) on each side of the track tamping machine, which are displaceable transversely to the longitudinal direction of the track tamping machine by means of a transverse displacement device, wherein the two tamping units (37, 38) on each side of the track tamping machine are equipped with at least two guide rails, in particular slide bars or slide tubes (2, 3), which are offset relative to one another in their height position and in the longitudinal direction of the track tamping machine, wherein each outer tamping unit (37) can be displaced transversely to the longitudinal direction of the track tamping machine by means of an adjusting drive (21) via its corresponding guide rail, and wherein the inner tamping unit (38) on the same guide rail can be displaced transversely to the longitudinal direction of the track tamping machine by means of the adjusting drive (21) independently of the outer tamping unit (37) . However, when the tamping operation is performed on the fourth rail area with a switch area far from the main line or a large bending degree, a long guide rail, a long slide bar or a long slide pipe needs to be arranged, so that the suspension extending distance of the tamping unit is too long, the lasting stability of the tamping operation in the switch area is affected, and the quality of the tamping operation in the switch area is directly affected, and therefore improvement is still needed.
Chinese patent No. ZL94101162.3 discloses a combined machine for tamping lines, consisting of a first and a second machine, which are connected to each other by means of a removable coupler. Each machine has a running drive and a machine frame supported on a rail-mounted mechanism, and a tamping unit with adjustable height. The machine of the first part, which is of greater length, is equipped with a switch tamping unit which can be moved laterally beyond the cross section of the machine frame by means of a drive. An auxiliary track lifting mechanism for adjusting the height and lateral position of the track switch by means of a drive mechanism is also provided for clamping a rail of a branch line of the track switch located beside the machine. An operation chamber is arranged in front of or behind the tamping unit. A cab is provided at each of the opposite ends of the first and second machines sharing the coupler. However, the second machine, which includes the auxiliary tamping tool, is equivalent to an independent switch tamping tool, because it has a frame, a track-following mechanism, a travel-driving mechanism, a cab, etc., and when tamping the switch area, the coupler with the first machine must be disengaged, and then the second machine must travel on the branch line of the switch to complete the tamping operation of the switch area. Therefore, in order to realize the full-coverage tamping operation of the turnout area, an independent turnout tamping vehicle needs to be replaced to a turnout area lane for operation, obviously, the technical scheme of the invention is too complex, the economical efficiency is not good, and the improvement is still needed.
