Description

Technical Field

[0001] This utility model patent relates to a track end buffer and anti-dropping device for monorail crane locomotives, which belongs to the auxiliary safety equipment for monorail crane operation. Background Art

[0002] Monorail cranes are currently the preferred auxiliary transport method for efficient transportation of goods and personnel in underground mines. They offer high carrying capacity, minimal tunnel space occupation, and flexible and adaptable operations. Lithium-electric monorail cranes, in particular, are environmentally friendly, energy-efficient, and have broad industrial application prospects and enormous market demand.

[0003] Monorail cranes run on a single suspended track at the top of an underground mine tunnel. The track layout at the start and end of the operation has open ends or end limit devices. At the start or end of the monorail crane operation, attention must be paid to the track end conditions to prevent it from derailing and causing safety accidents. Traditional track end derailment prevention adopts a rigid method, welding steel plates (anti-derailment plates) at the track end to block it. When approaching the end of the track, although the locomotive has been braked and the speed has been greatly reduced or it has stopped running 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 passengers have a poor experience, and there are certain safety hazards. Therefore, it is of great significance to design a safety device with buffering and anti-derailment to improve the stability and safety of locomotive operation.

[0004] Existing problems: The monorail locomotive operating track system has open ends or end limits at the starting and ending positions. To prevent the locomotive from accidentally derailing, a rigid method of welded steel plates is currently used to achieve this goal. However, this rigid method will cause the locomotive to collide with the anti-derailment plate at the end of the track. Although the collision occurs at a relatively low locomotive speed, it still causes damage to the locomotive and a poor experience for the driver and passengers because it has no buffer. In addition, under special circumstances, the locomotive may derail. Utility Model Content

[0005] In view of the above problems, the utility model designs a track end buffer and anti-derailment device for monorail crane locomotives, which reduces the collision degree between the locomotive and the track end limit device, alleviates locomotive damage, and reduces the probability of locomotive derailment.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The utility model discloses a track end buffering and anti-derailing device for a monorail crane, comprising a buffering and anti-derailing device at the front end of the monorail crane and a carrying trolley. The rear end of the buffering and anti-derailing device is connected to the front end of the monorail crane via a connecting seat. The upper front end of the buffering and anti-derailing device is connected to the carrying trolley, and the carrying trolley is arranged on the track and runs.

[0008] The front end of the buffer anti-derailment device is provided with a collision plate, and the middle is a guide cylinder and a guide rod.

When the trolley derails and falls, the guide rod and the rod seat are driven down to pull the brake lever, and the brake sensor senses and brakes the monorail locomotive.

[0014] The utility model is provided with an anti-collision mechanism and a spring buffer mechanism at the front end, which can reduce the collision degree between the locomotive and the track end limit device, alleviate the damage to the locomotive, and improve the experience of the driver and passengers.

DETAILED DESCRIPTION

[0020] The specific contents of the present invention are further described below:

[0021] The utility model provides a track end buffering and anti-derailment device for a monorail crane, comprising a buffering and anti-derailment device 3 and a carrying trolley 4 at the front end of a monorail crane 2. The rear end of the buffering and anti-derailment device 3 is connected to the front end of the monorail crane 2 via a connecting seat 5. The upper front end of the buffering and anti-derailment device 3 is connected to the carrying trolley 4, which is arranged to run on a track 1. The carrying trolley 4 is used to suspend and drive the buffering and anti-derailment device 3 to travel on the track.

[0022] This device buffers the anti-drop device 3 as Figure 1 and Figure 2 As shown, the front end of the buffer and anti-drop device 3 is provided with a collision plate 303, and the middle is a guide cylinder 301 and a guide rod 302. The guide rod 302 is inserted into the guide cylinder 301, and the outer end of the guide rod 302 is connected to the connecting seat 5. A spring 306 is also provided inside the guide cylinder 301. The side of the guide cylinder 301 is provided with a guide groove 304, which is arranged along the length of the guide cylinder 301. The guide rod 302 is provided with a sliding pin 305, which moves in the guide groove 304. The collision plate 303 is provided at the front end of the guide cylinder 301, and the rod seat 315 is provided at the rear end of the guide rod 302.

[0023] The connecting seat 5 is a pair of parallel connecting plates with coaxial pin holes. The connecting plates are connected to the mounting bracket 307 through the pins in the pin holes. The side of the mounting bracket 307 is L-shaped, with the vertical part fixing the hinge plate with holes on the top and the horizontal part at the bottom.

[0024] The rod seat 315 is hingedly connected to the vertical portion, and the hinge axis is arranged horizontally. The mounting bracket 307 and the connecting seat 5 are hingedly arranged vertically.

[0025] The brake sensor 308 is installed on the horizontal part of the mounting frame 307. A limit block 310 is provided on the outside of the guide cylinder 301 to limit the brake lever 311 on the brake sensor 308 to protrude toward the guide rod 302. The limit block 310 is located on the outer side of the guide cylinder 301 near the guide hole.

[0026] The limit block 310 is in the limit position where the brake lever 311 moves synchronously when the guide rod 302 is pressed into the limit position of the wire tube. When the brake lever 311 collides with the limit block 310, the monorail crane is braked.

[0027] The end of the brake lever 311 is connected to the rod seat 315 by a steel wire rope 312. When the trolley 4 falls off the track, the guide rod 302 and the rod seat 315 are driven to fall and pull the brake lever 311. The brake sensor 308 senses and brakes the monorail crane.

[0028] The working process of the utility model is as follows: when the monorail crane locomotive runs to the end of the track, the buffer anti-collision device designed by the utility model patent contacts the track end limiting component, the spring is compressed, and the kinetic energy of the locomotive is absorbed to prevent hard collision.

[0029] When the guide rod is compressed to the spring support limit, the brake lever of the brake sensor is touched by the limit block, which gives a signal to the locomotive braking system. The locomotive brakes until it finally stops, realizing the buffer limit effect.

[0030] When the track has no end limit components, the trolley will fall off the track. At this time, the sensor will be activated by the pulling of the wire rope and transmit the signal to the braking system of the monorail crane. The monorail crane will brake until it stops.

[0031] This new utility model incorporates an anti-collision mechanism and a spring buffer mechanism at the front end, minimizing collisions between the locomotive and the track end stop, alleviating damage to the locomotive and enhancing the driver and passenger experience. The front-end derailment brake mechanism reduces the probability of the locomotive derailing, improving safety and enhancing locomotive operation quality. This device can be added to existing single-track locomotives, enhancing the safety of existing products.
