Description

Technical Field

[0001] The utility model relates to supporting equipment in railway engineering, in particular to a flip derailer which derails a locomotive or a vehicle entering a protection section to ensure the safety of the protected object. Background Art

[0002] A derailer is a protective device on the track, used to protect people or important locomotives and vehicles on the track. Once a locomotive or vehicle enters the track, it will be derailed to ensure the safety of the protected object. Derailers are required to be installed at both ends of the train when the freight train is inspected at the arrival yard. If the locomotive slides, the derailer will force the locomotive to derail to protect human lives. In addition, derailers are also installed at both ends of some important locomotives and vehicles to protect the safety of these important locomotives and vehicles.

[0003] Existing derailers, such as "an outer shaft-connected traveling rotating derailer" disclosed in Chinese patent CN202703620U, include a derailing block, a base fixed to the outer side (right side) of the rail and an action rod for driving the derailing block to move, a derailing structure is provided on the derailing block, the base includes two side walls arranged at a front and rear interval, derailing block guide posts are provided on opposite sides of the two side walls, a connecting shaft guide groove with a middle height and left and right ends being low is provided at the upper ends of the two side walls, a guide arm is provided on the right side of the derailing block, a connecting shaft with two ends extending along the front and rear directions and guiding and moving with the corresponding connecting shaft guide groove is installed on the guide arm, a guide post matching groove matching with the derailing block guide post is provided on the right side of the guide arm, and the derailing block guide post extends into the corresponding guide post matching groove.

[0004] During use, when needing to go up the rail, the action bar moves to the left, and the action bar moves along the connecting shaft guide groove with the connecting shaft, and the derail block connected with the connecting shaft moves together with the connecting shaft, while moving to the left, the guide arm on the derail block is subjected to the action force of the derail block guide post on the base, with the connecting shaft as the center of a circle, with the contact point of the guide arm and the derail block guide post 22 as a fulcrum, with the guide arm as a power arm, the derail block is rotated around the connecting shaft and flipped to the upper side of the rail, when the connecting shaft is pushed to the other end of the connecting shaft guide groove by the action bar, the derail block tread guide plate lower surface of the derail block is close to the upper end surface of the rail, thereby completing the railing action of the derailer. When the action bar moves to the right, the derailer can be completed to flip to the lower rail action of the rail outside from the upper side of the rail.

[0005] The existing derailer has the following problems: in the prior art, there is only one side wall of the base, so the guide post of the derailing block can only be a cantilever structure supported at one end, and the support strength caused by the derailing block is insufficient, and it is easy to deform during use, which affects the service life of the entire derailer; in addition, it is also difficult to process the connecting shaft guide groove on the side wall. More importantly, the derailer is used outdoors, and the connecting shaft guide groove is easily sprayed with anti-skid sand by the locomotive sandblasting tube. In winter, snow will accumulate in the connecting shaft guide groove. When there is mud, sand or ice and snow in the connecting shaft guide groove, the mud, sand or ice and snow will jam or block the guide post of the derailing block, resulting in failure to derail normally. Utility Model Content

[0006] The utility model aims to provide a flip derailer to solve the technical problem that the derailing block guide column in the prior art is a cantilever structure supported at one end and is easily deformed during use, thus affecting the overall service life of the flip derailer.

[0007] In order to solve the above technical problems, a technical solution of a flip derailer in the utility model is as follows:

[0008] A flip derailer comprises a derail block, an action rod connected to the derail block through a connecting shaft, and a base fixed to the outer side of a rail when in use, a front derail block guide post and a rear derail block guide post arranged coaxially are arranged on the base, a connecting shaft guide structure with a middle height and low left and right ends matched with the connecting shaft is arranged on the base, the base comprises a front side vertical plate group and a rear side vertical plate group arranged at intervals in front and back, the two vertical plate groups are connected by a connecting piece, and the front side vertical plate group and the rear side vertical plate group each comprise two front and rear vertical plate groups arranged at intervals in front and back The two ends of the front derailment block guide column are arranged on the two vertical plates of the front side vertical plate group, the two ends of the rear derailment block guide column are arranged on the two vertical plates of the rear side vertical plate group, the derailment block is provided with two derailment block guide arms arranged with a front and rear interval, the two ends of the connecting shaft are arranged on the two derailment block guide arms, the derailment block guide arms are provided with guide column matching long holes matched with the corresponding derailment block guide column guides, and the connecting shaft guiding structure is arranged on the vertical plate at the rear position in the front side vertical plate group and the vertical plate at the front position in the rear side vertical plate group.

[0009] Furthermore, the connecting shaft guide structure is composed of the top surface of the vertical plate at the rear position in the front vertical plate group and the top surface of the vertical plate at the front position in the rear vertical plate group.

[0010] Furthermore, a plurality of reinforcing protrusion structures are arranged at intervals between the two derailment block guide arms on the derailment block.

[0011] Furthermore, the two derailing guide arms are provided with connecting shaft mounting holes for realizing rotational cooperation with the connecting shaft, and the matching long holes of each guide column are respectively located on the right side of the corresponding connecting shaft mounting holes.

[0012] Furthermore, the front derailment block guide post is detachably connected to the front side vertical plate group through a front side cotter pin; the rear derailment block guide post is detachably connected to the rear side vertical plate group through a rear side cotter pin.

[0013] Furthermore, the action rod includes a straight rod section extending in the left-right direction and a bent rod section connected to the left end of the straight rod section and extending upward, and the connecting shaft is connected to the upper end of the bent rod section.

[0014] The beneficial effects of the utility model are as follows: the working principle of the utility model is the same as that of the prior art, that is, when the upper rail needs to be flipped, the action rod moves to the left, the action rod moves along the connecting shaft guide structure with the connecting shaft, and the derailing block connected to the connecting shaft moves along with the connecting shaft. While moving to the left, the derailing block guide arm on the derailing block is subjected to the force of the corresponding derailing block guide column on the base, with the connecting shaft as the center of the circle, the contact point between the guide arm and the derailing block guide column as the fulcrum, and the derailing block guide arm as the power arm, so that the derailing block rotates around the connecting shaft and flips to the upper side of the rail. Different from the prior art, the front side vertical plate group and the rear side vertical plate group of the base both include two vertical plates spaced apart from each other in the front and rear directions, the two ends of the front derailment block guide column are arranged on the two vertical plates of the front side vertical plate group, and the two ends of the rear side derailment block guide column are arranged on the two vertical plates of the rear side vertical plate group. Both the front side derailment block guide column and the rear side derailment block guide column adopt a two-end support structure, which can improve the supporting strength of the derailment block guide column and reduce the deformation of the derailment block caused by the force-bearing process, thereby ensuring the service life of the flip derailer.

[0015] Furthermore, since each derailment block guide post adopts a support structure at both ends, the derailment block guide post can be detachably connected to the corresponding two vertical plates using a cotter pin, which facilitates maintenance and replacement when the derailment block causes problems.

[0016] Furthermore, since both the front and rear sides of the base adopt a double vertical plate structure, the connecting shaft guide structure can be composed of the top surface of the vertical plate at the rear position in the front vertical plate group and the top surface of the vertical plate at the front position in the rear vertical plate group. The connecting shaft guide structure does not use the guide groove structure in the prior art, thereby reducing the processing difficulty of the connecting shaft guide structure. At the same time, the connecting shaft guide structure is a supporting surface structure. When the connecting shaft moves up and down in the presence of mud, sand, ice and snow, the connecting shaft will not get stuck, and the mud, sand and snow can be automatically removed during the movement, thereby increasing the reliability of the equipment.
