Abstract
Description
Technical Field
[0001] This utility model belongs to the field of internal combustion locomotive technology, specifically relating to an emergency stop device for the front of an internal combustion locomotive. Background Technology
[0002] A diesel locomotive is a vehicle that uses a diesel engine as its prime mover and drives the wheels to rotate through a transmission device. Based on the type of fuel used in the diesel engine, the vast majority of diesel locomotives used on my country's railways are equipped with diesel engines. Diesel locomotives can move stably along the track. When a diesel locomotive is braking or making an emergency stop, two braking components generally operate simultaneously. One is the clamping and squeezing of the brake disc by the brake pads to lock the angle and position of the wheelset, thus enabling the diesel locomotive to stop suddenly. The other is the use of a spreader to spray sand of a specific size between the track and the wheelset, increasing the friction between the wheelset and the track, allowing the locked wheelset to stop suddenly.
[0003] When using existing spreaders, materials such as sand of a specific size are poured into the spreader, and then compressed gas is introduced through a side-connected pipe to propel the sand and other materials out through the discharge pipe on the spreader. The materials fall onto the track, assisting the locomotive head in making an emergency stop.
[0004] Existing spreaders can reliably spray materials such as sand, but they have certain problems in actual use. Specifically, the angle and position of the discharge pipe of the existing spreaders are locked, making it impossible to flexibly adjust the landing point of the sprayed material. In addition, the gap between the outlet of the discharge pipe and the track is too large. Under the wind force generated by the locomotive head during operation, the sprayed material is blown by the wind and cannot fall accurately between the track and the wheelset, affecting the overall emergency stopping effect of the locomotive head. Utility Model Content
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] To address the problems mentioned in the background section, the present invention adopts the following technical solution.
[0007] An emergency stop device for an internal combustion locomotive includes a feeder mounted on a bogie. An adjustment mechanism is installed on the side of the feeder. The feeder includes a storage bin, an air inlet pipe, and a feeding assembly. The storage bin is installed below the bogie. An air inlet pipe is installed on the side of the storage bin. A feeding assembly is installed at the bottom of the storage bin. Compressed air is introduced into the air inlet pipe to spray the material in the storage bin out of the feeding assembly. A wheelset is installed below the bogie and on the side of the feeder. The material sprayed out of the feeding assembly falls between the wheelset and the track. The adjustment mechanism is equipped with an adjustment component for adjusting the angle and bending of the feeding assembly.
[0008] As a preferred technical solution of this utility model, the adjustment component includes a blocking frame, a blocking plate, a pushing cylinder and a pushing block. The blocking frame is symmetrically arranged on the outside of the feeding component, the blocking plate is installed on the side of the blocking frame, and the pushing block is installed on the outside of the feeding component and on the side of the blocking frame. The pushing cylinder is installed on the side of the pushing block.
[0009] As a preferred technical solution of this utility model, the adjustment mechanism includes a mounting frame and a mounting plate. The mounting frame is symmetrically installed on the side of the storage compartment, and the mounting plate is installed below the mounting frame. The mounting plate is connected to the end of the blocking frame, and the pushing cylinder is connected to the side wall of the mounting plate.
[0010] As a preferred technical solution of this utility model, the feeding assembly includes a connecting pipe, a bent pipe and a feeding component. A connecting pipe is installed at the bottom outlet of the storage bin, a bent pipe is installed at the end of the connecting pipe, and a feeding component is installed at the end of the bent pipe. The connecting pipe, the bent pipe and the feeding component constitute a material discharge pipe.
[0011] As a preferred technical solution of this utility model, the bending tube is a metal gooseneck tube that can be bent and deformed, and the middle end of the bending tube is in contact with the outside of the blocking frame.
[0012] As a preferred embodiment of this utility model, the feeding component includes a feeding pipe, and the end of the bent pipe is equipped with a feeding pipe for ejecting material.
[0013] As a preferred embodiment of this utility model, the feeding component further includes an output pipe and a wind deflector. The output pipe is installed at the end of the bent pipe, and wind deflectors are installed on both sides of the outer side of the output pipe to block external wind.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In this invention, the feeder and adjustment mechanism, under the operation of the cylinder, adjust the angle and height of the feeder, control the distance between the opening at the end of the feeder and the track, reduce the drop of the material after it is sprayed out, and prevent the material from falling unstablely between the track and wheelset due to wind, thus affecting the emergency stopping effect of the internal combustion engine locomotive. Furthermore, the feeder in this invention includes a feed pipe, which can stably transport the material, allowing it to fall between the track and wheelset or directly onto the track, ensuring the overall stability of the device. The feeder also includes an output pipe and a wind deflector. The wind deflector reduces the impact of external wind on the material, allowing it to fall stably between the track and wheelset, and enhancing the friction between the wheelset and the track.

Detailed Implementation
[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.
[0027] Example 1
[0028] like Figure 1 As shown, this is a structural schematic diagram of the emergency stop device for the locomotive head in this embodiment. The emergency stop device for the locomotive head in this embodiment can adjust the position and angle of the discharge pipe, so that the material output from the discharge pipe can fall stably onto the track, ensuring the emergency stop effect of the locomotive head. The emergency stop device includes a spreader 1 installed on the bogie 3. An adjustment mechanism 2 for controlling the height and angle of the material output by the spreader 1 is installed on the side of the spreader 1. Multiple sets of wheelsets 4 are installed at the bottom of the bogie 3. The wheelsets 4 move along the track. The material sprayed by the spreader 1 falls between the wheelsets 4 and the track, increasing the friction between the wheelsets 4 and the track, and assisting the locomotive head in emergency stopping.
[0029] It is worth noting that there are multiple sets of spreaders 1, and the number of spreaders 1 corresponds to the number of wheelsets 4. The spreaders 1 are installed below the bogie 3, and the top of the adjustment mechanism 2 is connected to the lower surface of the bogie 3, which ensures the stability of the adjustment mechanism 2 in actual use.
[0030] As attached Figure 2 As shown, this is a schematic diagram of the structure of the spreader 1 in this embodiment. The spreader 1 includes a storage chamber 11, an air inlet pipe 12, and a feeding assembly 13. The storage chamber 11 serves as a storage chamber for materials such as sand. One end of the storage chamber 11 is connected to the air inlet pipe 12, and compressed gas is input into the storage chamber 11 through the air inlet pipe 12. The bottom end of the storage chamber 11 is connected to the feeding assembly 13. When the compressed gas enters the storage chamber 11 through the air inlet pipe 12, the material in the storage chamber 11 is pushed by the gas and discharged through the feeding assembly 13. The material falls stably onto the track.
[0031] It is worth noting that a closing plate is installed on the upper surface of the storage bin 11. The rotation and opening and closing of the closing plate facilitates the replenishment of materials such as sand in the storage bin 11 by subsequent operators.
[0032] As attached Figure 3 As shown, this is a schematic diagram of the feeding assembly 13 in this embodiment. The feeding assembly 13 mainly consists of a connecting pipe 131, a bent pipe 132, and a feeding component 133. The bottom of the storage bin 11 is equipped with a connecting pipe 131, and the end of the connecting pipe 131 is equipped with a bent pipe 132. The bent pipe 132 is a metal gooseneck tube, which can freely adjust its angle and direction. The end of the bent pipe 132 is equipped with a feeding component 133. After the material in the storage bin 11 passes through the connecting pipe 131 and the bent pipe 132, it is directly sprayed out from the opening at the end of the feeding component 133.
[0033] As attached Figure 5 As shown, it is a structural schematic diagram of the feeding component 133 in this embodiment. The feeding component 133 includes a feeding pipe 1331. The feeding pipe 1331 is installed at the end of the bent pipe 132. The feeding pipe 1331 is a hollow metal pipe. The feeding pipe 1331 stably sprays out the material transported by the bent pipe 132 and the connecting pipe 131.
[0034] As attached Figure 4 As shown, this is a schematic diagram of the adjustment mechanism 2 in this embodiment. The adjustment mechanism 2 includes a mounting frame 21, a mounting plate 22, and a blocking frame 23. The mounting frame 21 is symmetrically mounted on the side wall of the feeder 1. The mounting plate 22 is mounted on the bottom end of the mounting frame 21. The blocking frame 23 is symmetrically mounted between the mounting plates 22. The blocking frame 23 is attached to the upper and lower ends of the bent tube 132. The blocking plate 24 is mounted on the side of the blocking frame 23. A pushing cylinder 25 is mounted on one side of the inner wall of the mounting frame 21. A pushing block 26 is mounted on the output end of the pushing cylinder 25. The pushing block 26 is mounted on the outside of the feeding component 133. When the output end of the pushing cylinder 25 moves telescopically, the pushing block 26 is pushed. The feeder 133 is pushed at an angle, causing the bent tube 132 to bend. At this time, the blocking frame 23 and the blocking plate 24 limit and block the bent part of the bent tube 132, limiting the bending angle and position of the bent tube 132, and stabilizing the angle of the end opening of the feeder 133. This allows for adjustment of the distance between the end opening of the feeder 133 and the track as needed, ensuring that the material output by the feeder 133 falls stably between the track and the wheel set 4, reducing the influence of external wind. The blocking frame 23, the blocking plate 24, the pushing cylinder 25, and the pushing block 26 constitute the angle adjustment component of the feeder assembly 13.
[0035] It is worth noting that when the locomotive head makes an emergency stop, in order to avoid material spraying onto the outside of the wheelset 4 and splashing, the end of the feeder 133 can be almost perpendicular to the track, so that the material falls directly onto the track, allowing the wheelset 4 to make full contact with the sand and other materials on the track as it moves along the track.
[0036] Example 2
[0037] As attached Figure 6 As shown, it is a structural schematic diagram of the feeding component 133 in this embodiment. The difference between this embodiment and embodiment 1 is that the feeding component 133 in this embodiment includes an output pipe 1332 and a baffle plate 1333. The output pipe 1332 is installed at the end of the bent pipe 132, and the baffle plate 1333 is installed on the upper and lower sides of the output pipe 1332. The baffle plate 1333 blocks the end of the output pipe 1332, reducing the impact of external wind on the material discharged from the output pipe 1332, so that the material falls accurately between the wheel set 4 and the track.
[0038] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
