Description

Technical Field

[0001] This utility model patent relates to a track end buffer limit device for a monorail crane locomotive, belonging to the field of monorail crane equipment. Background Art

[0002] Monorail cranes are currently the preferred auxiliary transport system for efficient transportation of goods and personnel in underground mines. Monorail cranes are primarily categorized by power source, including diesel, lithium-ion batteries, battery-powered, pneumatic, and wire rope traction. They offer high carrying capacity, minimal tunnel space occupation, and flexible and adaptable operations. Lithium-ion monorail cranes, in particular, are environmentally friendly, energy-efficient, and have broad industrial application prospects and enormous market demand.

[0003] Monorail cranes operate on a single suspended track at the top of underground mine tunnels, and the track layout at the start and end of operations has open ends. Attention must be paid to the track end conditions at the start or end of a monorail crane's operation to prevent it from derailing and causing safety accidents. Traditional track end derailment prevention methods all use a rigid method, welding steel plates (anti-derailment plates) at the track ends to block them. When approaching the track end, although the locomotive has been braked and its speed has been greatly reduced or it has stopped when approaching the end, there is still a special situation where the locomotive hits the end anti-derailment plate. The impact load is large, the locomotive is easily damaged, the driver and passenger experience is poor, and there are certain safety hazards. Therefore, how to design a track end limit device with a buffer to improve the stability and safety of locomotive operation and enhance the driver and passenger experience is of great significance and value.

[0004] Monorail locomotive track systems have open ends at their starting and ending points. To prevent the locomotive from accidentally derailing, a rigid method using welded steel plates is currently used. However, this method can lead to collisions between the locomotive and the anti-derailment plates at the track ends. Although these collisions occur at relatively low locomotive speeds, they can still cause damage to the locomotive and a poor ride experience for the driver and passengers. Utility Model Content

[0005] In view of the above problems, the utility model designs an end buffer limiter for a monorail locomotive running track, which reduces the collision degree between the locomotive and the track end limiter and alleviates the damage to the locomotive.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a track end buffer limiter for a monorail crane locomotive, which is arranged at the end position of the monorail crane track.

[0007] It includes a motion buffer plate, a spring, a fixed buffer plate and a pair of fixed plates; the two fixed plates clamp the monorail hanging track and are arranged on the outside of the end portion, the fixed plates are provided with fixing holes located above and below the monorail hanging track, and the fixing holes of the two fixed plates are connected by bolts;

[0008] The fixed buffer plate is arranged at the inner edge of the fixed plate relative to the end of the track, the spring is arranged between the fixed buffer plate and the moving buffer plate, and a guide pin is arranged in the spring.

[0009] According to the track end buffer limit device for monorail crane, it is characterized in that the moving buffer plate and the fixed limit plate are provided with a limit plate on the spring side, the middle of the limit plate is a limit hole, and the end of the spring is sunk into the limit hole on the moving buffer plate.

[0010] According to the track end buffer limit device for monorail crane, it is characterized in that a guide pin hole is opened in the middle of the fixed buffer plate, one end of the guide pin is fixed to the moving buffer plate, and the other end passes through the guide pin hole of the fixed buffer plate, and the guide pin passes through the side of the fixed buffer plate and is fixed with an external bolt and a nut.

[0011] According to the track end buffer limit device for monorail crane locomotive, it is characterized in that a moving buffer plate, a spring and a fixed buffer plate are respectively provided on both sides of the monorail track, and the structure is symmetrical, and the two fixed buffer plates are respectively welded to the fixed plates of the monorail crane twice.

[0012] According to the track end buffering and limiting device for a monorail crane vehicle, it is characterized in that the outer side surface of the fixed plate is provided with reinforcing ribs connecting the fixed plate and the fixed buffer plate.

[0013] According to the track end buffer limit device for monorail crane locomotive, it is characterized in that the fixed buffer plate and the movable buffer plate are provided with a gap in the middle for the monorail crane track to pass through.

[0014] The advantages of the present invention are:

[0015] When the monorail crane reaches the end of the track, the locomotive contacts the track end buffer limiter designed by this utility model. The spring compresses, absorbing the locomotive's kinetic energy, and the locomotive eventually stops running, achieving a buffer limiter effect. This reduces the degree of collision between the locomotive and the track end limiter and alleviates damage to the locomotive.

[0016] The structure is simple, stable and reliable, and can be installed at any position, suitable for installation without changing the track. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The specific structure of the utility model is further described below: This device is applied to a monorail hanging track and is used for buffering and limiting the locomotive at the end of the track.

[0021] The device is arranged at the end position of the monorail hanging track 1, and includes a moving buffer plate 2, a spring (9), a fixed buffer plate and a pair of fixed plates 6; the two fixed plates 6 clamp the monorail hanging track 1 and are arranged on the outer side of the end, and the fixed plates 6 are provided with fixing holes located above and below the monorail hanging track 1, and the fixing holes of the two fixed plates 6 are connected by bolts.

[0022] The fixed buffer plate is provided at the inner edge of the fixed plate 6 relative to the track end. The spring 9 is provided between the fixed buffer plate and the moving buffer plate 2. The spring 9 is provided with a guide pin 4. When the monorail crane vehicle reaches the end and still has a certain speed, it impacts the moving buffer plate, which compresses the spring. The spring then acts on the fixed buffer plate and the fixed plate, completely braking the vehicle.

[0023] The moving buffer plate 2 and the fixed buffer plate are provided with a limit plate 3 on the spring (9) side. The middle of the limit plate 3 is a limit hole. The end of the spring (9) is sunk into the limit hole on the moving buffer plate 2. A guide pin 4 hole is opened in the middle of the fixed buffer plate. One end of the guide pin 4 is fixed to the moving buffer plate 2, and the other end passes through the guide pin 4 hole of the fixed buffer plate. The guide pin 4 passes through the external bolt set on the side of the fixed buffer plate and is fixed with a nut.

[0024] A moving buffer plate 2, a spring (9) and a fixed buffer plate are respectively provided on both sides of the monorail track, and the structure is symmetrical. The two fixed buffer plates are respectively welded to the fixed plates 6 of the monorail crane twice. The symmetrical buffer plate structure decelerates the monorail crane locomotive and avoids the locomotive running deviation caused by a single deceleration.

[0025] The outer side of the fixed plate 6 is provided with a reinforcing rib connecting the fixed plate 6 and the fixed buffer plate. The reinforcing rib strengthens the connection strength between the fixed buffer plate and the fixed plate.

[0026] The fixed buffer plate and the moving buffer plate 2 of the device can also be provided as an integral plate with a notch in the middle, and the middle hole is used for the monorail hanging track 1 to pass through.

[0027] Working principle: When the monorail crane locomotive runs to the end of the track, the locomotive contacts the track end buffer limit device designed by the utility model patent, the spring is compressed, and the kinetic energy of the locomotive is absorbed. The locomotive eventually stops running, realizing the buffer limit effect.
