Abstract

The utility model includes a pulling jack 1, a lever 2, which is mounted on a metal base 6 through a bushing. On the base 6 there are several holes for installing the lever 2, which allows you to change the distance and installation angle of the device for straightening the supports. Thanks to this, the straightening process can be carried out in cramped conditions. A guide rail 5 and a pulling jack 1 are attached to the body of the support 3 with metal clamps 4, which is also connected to the lever 2 through a movable hinge. The clamps 4 have different configurations depending on the type of support being straightened. The device for straightening supports is a prefabricated structure, which greatly simplifies the process of transportation, storage and straightening. On the body of the support 3 at a certain height, metal clamps 4 are fixed with a guide rail and a pulling jack 1, which is extended to the maximum possible distance necessary to straighten the support. Then a lever 2 is attached to the jack 1 on a swivel joint and secured to a suitable hole in the metal base 6, which is previously pressed into the ground. The pulling jack 1 is activated by acting on its handle. Lever 2 begins to slide along the guide rail 5, which at the same time works in compression and transmits force to the body of the support 3. In this case, the effective force, due to the design used, is reduced, due to which the metal consumption of the straightening device can be reduced. The force that is transmitted to support 3 causes it to deflect to the required vertical position. Due to the movable lever 2, which slides along the guide rail 5, the stroke length of the jack rod 1 is reduced.

Description

The utility model relates to railway equipment and is intended for straightening reinforced concrete supports of a contact network, and can be used for straightening supports with an inclination relative to design parameters and maintaining the integrity of the support body.

A device for leveling contact network supports is known, containing a counterweight frame with counterweights, which is mounted on the straightened support using grips; jacks are installed at the free end of the frame (see Application for invention No. 94028487, IPC E04N 12/34, publication 12/27/1995 ).

There is a known complex for straightening overhead contact network supports, which includes a crane with a telescopic boom, a removable support gripping mechanism, mounted on a common transport platform (see Russian Federation Utility Model Certificate No. 31595, MPK E04N 12/34, publication 08/20/2003).

The closest analogue of the claimed utility model is a device for straightening contact line supports, including a jack consisting of a welded base, a stop, a screw and a drive mechanism with a screw handle. (see Utility model certificate RF111567, MPK E04N 12/34, publication 12/20/2011), accepted as a prototype.

The main disadvantage of the prototype is the uneven distribution of the load on the support and the large weight of individual parts of the structure.

The proposed utility model differs from known analogues and the prototype in its compact assembly and movable point of contact with the support.

The problem to which the useful model is aimed is to increase the reliability of the alignment of supports in cramped conditions, as well as to reduce the load acting on the support and a more uniform distribution of force.

The technical result achieved by implementing the claimed utility model is to increase the reliability of the straightening process, as well as the area of use of the device for straightening supports due to the use of a guide rail with a movable lever.

The specified technical result is achieved by the fact that a device for straightening supports contains a jack, a stop, two clamps for attaching the device to the support, characterized in that the device contains a guide rail secured with clamps to the support, along which a lever moves, ensuring reliable alignment of the support.

The utility model is illustrated by drawings:

in fig. 1 - process of straightening the support;

in fig. 2 - appearance and dimensions of the structure.

The device for straightening the supports includes a pulling jack 1, a lever 2, which is installed on a metal base 6 through a bushing. On the base 6 there are several holes for installing the lever 2, which allows you to change the distance and installation angle of the device for straightening the supports. Thanks to this, the straightening process can be carried out in cramped conditions. A guide rail 5 and a pulling jack 1 are attached to the body of the support 3 with metal clamps 4, which is also connected to the lever 2 through a movable hinge. The clamps 4 have different configurations depending on the type of support being straightened. The device for straightening supports is a prefabricated structure, which greatly simplifies the process of transportation, storage and straightening.

The device for straightening the supports operates as follows.

A pre-dig is dug in and a pit is made near the support to be straightened. On the body of the support 3 at a certain height, metal clamps 4 are fixed with a guide rail and a pulling jack 1, which is extended to the maximum possible distance necessary to straighten the support. Then a lever 2 is attached to the jack 1 on a swivel joint and secured to a suitable hole in the metal base 6, which is previously pressed into the ground.

If necessary (in weak or waterlogged soils), in order to more reliably support lever 2 in the ground, additional supports in the form of wooden beams or concrete blocks are placed under the stop 6.

The pulling jack 1 is activated by acting on its handle. Lever 2 begins to slide along the guide rail 5, which at the same time works in compression and transmits force to the body of the support 3. In this case, the effective force, due to the design used, is reduced, due to which the metal consumption of the straightening device can be reduced. The force that is transmitted to support 3 causes it to deflect to the required vertical position. Due to the movable lever 2, which slides along the guide rail 5, the stroke length of the jack rod 1 is reduced.

The use of the proposed device for straightening supports makes it possible to increase the reliability of support straightening, simplifies work in hard-to-reach places, as well as when transporting the device to the place of work, installation and dismantling.

The proposed utility model can be used in work on leveling inclined railway supports, while the design of the device for straightening the supports makes it possible to increase the reliability of the straightening process and can be used in cramped conditions.
