Description

Technical Field

[0001] The present invention relates to the technical field of rail locomotives, and in particular to a locomotive coupler equalizing beam anti-detachment device. Background Art

[0002] Currently, the installation height of couplers on domestic locomotives is 880±10mm. To meet the requirements of coupler connection height difference and left-right swing, the coupler is generally adjusted by a coupler equalizer beam, which allows the coupler to float up and down relative to the rail surface. The equalizer beam is hung on the frame via a hanger. Because the equalizer beam is simply hung on the hanger without any fastening connection, it often falls off due to locomotive vibration on sections with poor track quality. The loss of the equalizer beam poses a safety hazard to driving. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a locomotive coupler equalizer beam anti-detachment device; it can effectively ensure that the equalizer beam is always connected to the vehicle body during the swinging and up and down jumping of the coupler, so as to prevent it from falling off and causing locomotive accidents.

[0004] The solution adopted by the present invention to solve the technical problem is:

[0005] A locomotive coupler equalizing beam anti-detachment device includes a boom seat, a boom vertically arranged and used in conjunction with the boom seat, an equalizing beam hung on one end of the boom away from the boom seat, and a rope; the boom seat, the boom, and the equalizing beam form an installation chamber for installing the coupler, and the rope is wound around the outside of the installation chamber and connected to the top of the boom and the bottom of the equalizing beam.

[0006] The coupler is located in the installation chamber, the boom seat is also installed on the car body and arranged on the same side as the coupler, the two ends of the boom are respectively hung on the boom seat and the equalizing beam, the rope is located outside the installation chamber and connected to the top of the boom and the bottom of the equalizing beam, and the rope is in a loose state; during use, the coupler moves in the installation chamber, thereby driving the equalizing beam to move, and the addition of the rope prevents the equalizing beam from falling off from the boom, effectively avoiding locomotive accidents caused by the falling of the equalizing beam.

[0007] In some possible implementations, in order to effectively position the rope at the top of the boom, a nut A is provided at the top of the boom away from the top, and one end of the rope passes through the nut A.

[0008] In some possible embodiments, in order to effectively position the rope at the top of the boom and the bottom of the equalizing beam, the rope forms a closed loop around the outside of the installation chamber; a nut B is provided on the side of the equalizing beam away from the boom seat, and the other end of the rope passes through the nut B and is connected to the end thereof passing through the nut A.

[0009] One end of the rope passes through the threaded hole in nut A, and the other end passes through the threaded hole in nut B, and then the two ends are connected to form a closed loop wrapped around the outside of the installation chamber; in order not to affect the follow-up movement of the equalizing beam and the coupler, the closed loop formed by the rope is in a loose state; the loose state described here means that the length of the closed loop formed by the rope is greater than the sum of the length of the boom, the length of the equalizing beam, and the length of the boom seat.

[0010] In some possible embodiments, there are two hangers; the balancing beam includes a base plate located at the bottom of the hanger seat, and lifting ears connected to both ends of the base plate and symmetrically arranged; the two lifting ears are respectively hung with two hangers; the nut B is installed on the side of the base plate away from the hanger seat.

[0011] The two booms are respectively connected to the boom base, and the other ends are connected to the lifting ears to form an installation chamber;

[0012] Preferably, the threaded holes of the nuts A on the two suspension rods are also coaxially arranged and parallel to the axis of the nut B.

[0013] In some possible implementations, in order to effectively ensure that a portion of the rope is always located at the bottom of the equalizing beam, the number of the nuts B is at least two and they are evenly arranged along the long direction of the bottom plate.

[0014] Two nuts B are located at the bottom of the base plate and are coaxial;

[0015] In some possible implementations, in order to effectively realize the connection between the boom and the equalizing beam, a U-shaped opening groove is provided on the side where the lifting ears are away from each other; and the opening of the U-shaped opening groove is provided on the side where the lifting ears are away from each other.

[0016] In some possible implementations, a hooking member 1 for use with the U-shaped opening groove is provided at one end of the suspension rod close to the suspension ear.

[0017] In some possible implementations, both ends of the rope are connected by a rope clamp.

[0018] In some possible implementations, the rope is a steel wire rope for durability and longer service life.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention effectively prevents the equalizing beam from being separated from the boom during the following movement of the coupler and the equalizing beam by setting a rope, thereby effectively avoiding locomotive accidents and effectively improving driving safety.

[0021] The present invention installs nut A on the top of the boom and nut B on the bottom of the equalizing beam to limit the position of the rope through nuts A and B, thereby effectively preventing the rope from falling off.

[0022] The present invention can effectively ensure that the balancing beam and the coupler move with each other by connecting the two ends of the rope to form a closed loop in a loose state. BRIEF DESCRIPTION OF THE DRAWINGS
