Description

Technical Field

[0001] This utility model specifically relates to the technical field of anti-runaway vehicle mechanisms, and more specifically to an anti-runaway vehicle mechanism for an inclined monorail. Background Technology

[0002] Monorails are commonly used for transporting materials, equipment, and personnel in underground coal mines, mining operations, and some industrial plants. When the monorail track is tilted, the monorail locomotive or its carrying vehicle is prone to slippage when stopped due to the force of gravity, which may lead to serious accidents such as equipment damage and personal injury. Therefore, a reliable anti-slippage mechanism must be installed to ensure safety.

[0003] Traditional anti-slip methods, such as simple manual braking devices or friction-based braking structures, lack sufficient reliability and stability when facing complex working conditions and unexpected situations. Manual braking devices rely on manual operation, resulting in slow response times and a high risk of operational errors; friction-based braking structures become significantly less effective when the track surface is wet or oily, failing to effectively prevent slippage. Traditional monorail trolley anti-slip mechanisms are deficient in stability and reliability, making it difficult to meet the requirements of complex working conditions and high-precision operations. Utility Model Content

By installing the anti-slip mechanism and the anti-vehicle mechanism with the monorail trolley, the monorail trolley has dual protection, which greatly improves safety; thus solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-8In this embodiment of the utility model, an anti-slip mechanism for an inclined monorail hoisting track includes a monorail trolley 1, on which a car-stopping mechanism 3 and an anti-slipping mechanism 2 are symmetrically installed on both sides; the car-stopping mechanism 3 is located at the front end of the anti-slipping mechanism 2.

[0032] The anti-slip mechanism 2 includes a fixed base 21, which is symmetrically arranged. The bottom of the fixed base 21 is fixedly connected to the upper surface of one end of the mounting platform 16. The upper end of the symmetrically arranged fixed base 21 is fixedly connected to the L-mounting frame 22. The inner side of the end of the L-mounting frame 22 is provided with a bearing 23, which is rotatably connected to the rotating rod 25. The outer side of the end of the L-mounting frame 22 is provided with a limiting ring 24. The front end of the rotating rod 25 is provided with a fixing ring 27, which is rotatably connected to the limiting ring 24. The end of the rotating rod 25 is fixedly connected to the auxiliary slide 26, which is slidably connected to the track 18.

[0033] By adopting the above technical solution, the anti-slip mechanism 2 and the vehicle blocking mechanism 3 are symmetrically installed on both sides of the monorail trolley 1, so that the force is evenly distributed, avoiding stress concentration on one side and improving the overall stability.

[0034] The anti-slip mechanism 2 generates resistance in advance through mechanical contact, reducing the slippage speed and the impact force during emergency braking, thus preventing the monorail trolley 1 or goods from shaking or derailing due to sudden braking. The rotating rod 25 on the anti-slip mechanism 2 can rotate flexibly through the bearing 23 and the limit ring 24, which can adapt to changes in the slope of the track 18 or the posture adjustment of the monorail trolley 1, ensuring that the anti-slip function is always effective.

[0035] In this embodiment, the other end of the mounting platform 16 is symmetrically provided with a lower rotating ear plate seat 17. The upper end of the lower rotating ear plate seat 17 is rotatably connected to the upper rotating ear plate 31. The upper rotating ear plate 31 is symmetrically provided on the lower surface of the mounting base 32.

[0036] The mounting base 32 has a cylinder rotating seat 33 on one inner side, the cylinder rotating seat 33 is rotatably connected to the telescopic cylinder 34, the other end of the telescopic cylinder 34 is rotatably connected to the claw 36, and the claw 36 is connected to the track 18.

[0037] A pawl rotating platform 35 is mounted on the upper surface of the other end of the mounting base 32. The guide rod on the pawl rotating platform 35 is rotatably connected to the pawl 36. A buffer spring assembly 37 is connected to the guide rod on one side of the pawl rotating platform 35.

[0038] The mounting platform 16 is symmetrically mounted on the lower surface of the frame 11. Wheels 12 are symmetrically arranged on the inner side of the upper end of the frame 11, and the symmetrically arranged wheels 12 are slidably connected to the rail 18. A buffer block 15 is provided in the middle of the frame 11.

[0039] A motor mounting bracket 13 is installed on the upper surface of the frame 11, and a rotary motor 14 is installed on the motor mounting bracket 13. The end of the rotary motor 14 is connected to one of the wheels 12.

[0040] By adopting the above technical solution, the braking mechanism 3 uses the claws 36 driven by the telescopic cylinder 34 to grip the track 18, which has strong braking force and rapid response, and can stop the vehicle within a short distance. It is especially suitable for inclined track scenarios to prevent the vehicle from slipping due to gravity. The buffer spring assembly 37 absorbs the impact energy when the claws 36 brake, reduces mechanical wear and vibration, extends the equipment life, and improves the smoothness of the braking process.

[0041] The working principle of this utility model is as follows: the fixed seat 21 supports the rotating rod 25 through the L-mount bracket 22, the bearing 23 and the limiting ring 24 ensure that the rotating rod can rotate flexibly, and the auxiliary slide 26 at its end slides in contact with the track 18; when the monorail trolley 1 is traveling normally on the inclined track 18, the auxiliary slide 26 slides with the track 18, and the rotating rod 25 maintains its initial angle and does not hinder the movement of the trolley; when the monorail trolley 1 slips, the auxiliary slide 26 slides faster relative to the track 18 due to inertia or gravity, which drives the rotating rod 25 to rotate around the bearing 23, causing the rotating rod to tilt towards the track 18, generating resistance through friction or mechanical obstruction, and slowing down the slipping speed;

[0042] The anti-slip mechanism 2 generates resistance in advance through mechanical contact, reduces the slipping speed, reduces the impact force during emergency braking, and avoids the monorail trolley 1 or goods from shaking or derailing due to sudden braking. The rotating rod 25 on the anti-slip mechanism 2 can rotate flexibly through the bearing 23 and the limit ring 24, which can adapt to the changes in the slope of the track 18 or the posture adjustment of the monorail trolley 1, ensuring that the anti-slip function is always effective.

[0043] During normal operation, the telescopic cylinder 34 on the braking mechanism 3 is in the retracted state, and the claw 36 is separated from the track 18, which does not affect the movement of the monorail trolley 1. When emergency braking is required, the telescopic cylinder 34 extends rapidly, pushing the claw 36 to rotate around the guide rod of the claw rotating platform 35, so that the claw quickly grips the track 18. At this time, the buffer spring assembly 37 absorbs the impact energy through elastic deformation, avoiding structural damage caused by rigid collision, and at the same time provides continuous braking force to stop the monorail trolley 1 from moving.

[0044] The braking mechanism 3 uses a chuck 36 driven by a telescopic cylinder 34 to grip the track 18, providing strong braking force and rapid response. It can stop the vehicle within a short distance, making it particularly suitable for inclined track scenarios to prevent slippage accidents caused by gravity. The buffer spring assembly 37 absorbs impact energy when the chuck 36 brakes, reducing mechanical wear and vibration, extending equipment life, and improving the smoothness of the braking process.

[0045] The anti-slip mechanism 2 and the anti-rollover mechanism 3 are symmetrically installed on both sides of the monorail trolley 1, so that the force is evenly distributed, avoiding stress concentration on one side and improving the overall stability.
