Definitions

the invention relates to a hydraulic pressure and drawing device, in particular for railroad tracks, for mechanical compensation of climate-related influences during the continuous welding of railroad tracks.
the smallest climate-related changes in length of continuously welded railroad tracks are achieved by welding the individual railroad tracks to one another at an average annual temperature.
the invention eliminates these disadvantages by proposing a hydraulic pushing and pulling device, which is characterized in that only free piston surfaces come into effect both in pulling and in pushing operation.
the subject matter of the invention is defined in claims 1 to 14.
the hydraulic pushing and pulling device is further characterized in that it has at least one hydraulic cylinder which can be turned through 180 ° together with a pair of articulated levers which act on one rail track and on the other at the opposite end of the device a corresponding one , on the other rail track engaging pair of articulated levers, which can also be turned through 180 °.
the device is switched to pull and push operation and always the same free piston surface is brought into the working position.
This construction ensures that the device works with maximum and identical force ratios in both the push and pull mode.
the device can be easily dismantled and can be arranged on the rail tracks during operation so that emergency train operation can also take place if necessary, which is advantageous in the context of repair work.
the device according to FIGS. 1, 2 and 3 has two cross members 5 and 6, which are passed under the rail tracks 43 and 44. They have profile-matching adapters 27 for the base of the rails 43 and 44. At the outer ends of the crossbeams, journals 7, 8, 9 and 10 project vertically upwards, onto which articulated levers 1, 2, 3 and 4 can be attached.
the articulated levers 1, 2, 3 and 4 have contact shoes 1a, 2a, 3a and 4a. These consist of a wear material that is particularly well suited for adhesion to the rail web. They have profiles 45, which increase liability.
the screws 46 are provided for the detachable attachment of the system shoes.
the guide cages 51 and 52 have fastening eyes 37 and 39, which cooperate in the pulling operation via articulated bolts 34 with articulated forks 32 and 33 of pull or push rods 30 and 31, which in turn via articulated forks 21 and 22 at the outer ends 3b, 4b of the articulated levers 3 and 4 are articulated.
the hydraulic pressure cylinders 23 and 24 For the printing operation according to FIG. 2 (pushing apart the rails 43, 44), the hydraulic pressure cylinders 23 and 24 have fastening eyes 38 and 40 at their ends, which thereby, secured against buckling, into the pockets 32 'and 33' of the articulated forks 32 and 33 the rods 30 and 31 now acting as push rods interact.
the hydraulic pressure cylinders 23 and 24 are connected to a hydraulic pump 42 via lines 35 and 36.
the active hydraulic unit 23, 24 including guide cages 51, 52 is connected at 34 to the rods 30 and 31 which are subjected to tension.
the articulated levers 3 and 4 with their bearings 13, 14 are temporarily withdrawn from the pins 9, 10, turned through 180 ° and put back on.
the ends 3c, 4c and 1c, 2c of the articulated levers 3, 4 and 1, 2 engaging the rail webs 55 are directed away from the rail joint 50 in their arrowing.
each cylinder and guide unit 23/51 or 24/52 individually, as shown in FIG. 2 is shown.
all that is required is the temporary loosening of the bolts 15 and 16, the repositioning of the articulated levers 1 and 2 by lifting their bearings 11 and 13 from the pins 7 and 8 of the cross member 5 and turning them 180 °.
an adjustable limit stop 28 is provided, which on the one hand on the detachable bolts 15 and 16 on the articulated levers 1 and 2 and on the other hand via a ring 29 on the hydraulic cylinders 23 and 24 is set.
the device is suitable for quick and easy implementation of push and pull operations and vice versa. Due to the limit stop 28, it can work exactly according to the respective temperature conditions. By means of the pressure pump 42, which can also be operated by hand, the device operates without external energy, so that it can be used at any point in the route network.
the train operation can continue - if the rail joint 50 is not too large or is temporarily bridged during the work.
the pull or push rods 30 and 31 and their connection to the adjacent parts can also be designed differently, i.e. for example, more stable, and have additional devices against buckling at higher pressure forces.
