Description

Technical Field

[0001] This utility model relates to the field of locomotive manufacturing technology, and in particular to a cylinder structure and a locomotive. Background Technology

[0002] The main air reservoir is a crucial component of the railway locomotive braking system. Its function is to store compressed air, processed by a dryer and filter, for use by the locomotive braking system and auxiliary equipment. Normally, the main air reservoir of an electric locomotive is installed inside the locomotive's engine room via a mounting bracket. However, in special cases, due to space constraints, it may be necessary to suspend the main air reservoir below the locomotive underframe.

[0003] The existing locomotives use a clamp-on system to secure the air cylinders, which are mounted under the locomotive's underframe. If the clamp breaks and detaches, the air cylinder may fall, posing a safety hazard. Typically, a steel cable is installed between the air cylinder and the frame. However, if the clamp breaks, the entire weight of the air cylinder rests on the steel cable. Since the steel cable sways with locomotive traction or braking, the air cylinder is at risk of impact. Therefore, in this situation, the mining locomotive is unsuitable for continued operation. If the distance to the maintenance location is far, to ensure safety, the disabled locomotive must be towed there via rescue, which would disrupt shift work and reduce the locomotive's operational efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a cylinder structure and locomotive that solves the problem that damage or breakage of the chuck on the cylinder in the prior art would delay the locomotive's operating efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution: The present invention provides a cylinder structure, including a cylinder body, a strap attached to the cylinder body, a fixing frame installed on the upper side of the cylinder body, the fixing frame being a rigid structure, and the fixing frame and the strap being connected to the chassis respectively.

[0006] Preferably, two sets of fixing brackets are welded to the upper side of the air cylinder body.

[0007] Preferably, two sets of U-shaped plates are formed on the underside of the locomotive, each U-shaped plate corresponding to a fixed frame. An mounting sleeve is formed on each U-shaped plate, and a bolt is installed upside down inside the mounting sleeve. The fixed frame is placed on the upper side of the mounting sleeve, and the bolt passes through the fixed frame and is tightened with a nut.

[0008] Preferably, a groove is formed inside the mounting sleeve, the groove has a T-shaped cross-section, and the bolt slides within the groove.

[0009] Preferably, the chassis is equipped with a steel wire rope, with both ends of the steel wire rope connected to the underside of the chassis. The main body of the air cylinder passes through the U-shaped area formed by the steel wire rope and the chassis. Along the axial direction of the main body of the air cylinder, the steel wire rope is positioned between the fixing frame and the clamping belt.

[0010] Preferably, the cartridge includes a first connecting strap and a second connecting strap, which are connected to each other to form a placement area, and the air cylinder body is inserted into the placement area.

[0011] Preferably, the chassis is equipped with a first fixing pin, and the first connecting strip is bent and hooked onto the first fixing pin.

[0012] Preferably, the chassis is equipped with U-bolts, which are fastened to the chassis by fasteners, and the second connecting strip is bent and hooked onto the U-bolts.

[0013] Preferably, the first connecting strap and the second connecting strap are connected by a connecting bracket, on which a first connecting rod and a second connecting rod are installed side by side.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0021] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0024] In the current technology, the main body of the air cylinder on the underside of the locomotive is fixed to the underside of the locomotive chassis by two methods: clamps and steel wire ropes. Under normal conditions, the steel wire rope is not under stress. If the clamp breaks, the main body of the air cylinder will be pressed against the steel wire rope. However, the steel wire rope will swing back and forth, causing the main body of the air cylinder to be unstable and swing back and forth. This will prevent the locomotive from working normally, disrupt the operation time, and reduce the operation efficiency.

[0025] To solve the above problems, such as Figures 1 to 3As shown, this utility model provides a cylinder structure, including a cylinder body 1, a strap 2 attached to the cylinder body 1, a fixing frame 3 installed on the upper side of the cylinder body 1, the fixing frame 3 being a rigid structure, and the fixing frame 3 and the strap 2 being connected to the chassis 20 respectively. Typically, the cylinder structure is located on the lower side of the locomotive chassis 20.

[0026] In normal operation, the cylinder body 1 is mainly fixed by the cassette 2. Even if the cassette 2 breaks or fails, the fixing bracket 3 can still maintain the connection with the cylinder body 1. At the same time, the fixing bracket 3 is a rigid structure. When the fixing bracket 3 is connected to the cylinder body 1, there will be no relative shaking between the cylinder body 1 and the chassis 20, so that the cylinder body 1 can remain stable. Even if the cassette 2 fails, the fixing bracket 3 can still play a fixing role. The cylinder structure of this utility model increases the number of rigid connection points, so that if the rigid connection points, such as the cassette 2, fail, they can be fixed by the fixing bracket 3 to avoid large shaking of the cylinder body 1.

[0027] Two sets of fixing brackets 3 are welded to the upper side of the air cylinder body 1. The two sets of fixing brackets 3 are welded to the outer wall of the air cylinder body 1 to increase the connection points between the air cylinder body 1 and the vehicle chassis 20. If one set of connection fails, the remaining connection can continue to fix the air cylinder body 1.

[0028] Two sets of U-shaped plates 4 are formed on the underside of the locomotive. The U-shaped plates 4 correspond one-to-one with the fixing frame 3. The mounting sleeves 5 are formed on the U-shaped plates 4. The bolts 6 are installed upside down inside the mounting sleeves 5. The fixing frame 3 is placed on the upper side of the mounting sleeves 5. The bolts 6 pass through the fixing frame 3 and are tightened with nuts.

[0029] The main body 1 of the air cylinder of this utility model is fixed by bolts 6, realizing the detachable connection between the fixing frame 3 and the U-shaped plate 4. This makes it easier for maintenance personnel to carry out maintenance after increasing the rigid connection of the fixing frame 3, and reduces the difficulty of disassembly and installation.

[0030] The mounting sleeve 5 of this utility model has a groove 7 formed inside. The cross-section of the groove 7 is T-shaped. The bolt 6 slides in the groove 7. The head of the bolt 6 is placed in the end area of ​​the groove 7. The bolt 6 is in an inverted state. Then, a nut is screwed on the bolt 6 to connect the fixing bracket 3 and the U-shaped plate 4. The bolt 6 in the groove 7 can change its own installation position to adapt to the fixing bracket 3 of different lengths. The bolt 6 can pass through the through holes at different positions on the fixing bracket 3, so that the U-shaped plate 4 on the vehicle chassis 20 can adapt to the air cylinder body 1 of different sizes.

[0031] A steel wire rope 8 is installed on the chassis 20, with both ends of the steel wire rope 8 connected to the underside of the chassis 20. The air cylinder body 1 is inserted into the U-shaped area formed by the steel wire rope 8 and the chassis 20. Along the axis of the air cylinder body 1, the steel wire rope 8 is positioned between the fixing frame 3 and the clamping belt 2. In this invention, the steel wire rope 8 is installed on the chassis 20 between the fixing frame 3 and the clamping belt 2. When both the fixing frame 3 and the clamping belt 2 fail to connect to the air cylinder body 1, the steel wire rope 8 will pull the air cylinder body 1, preventing it from falling and improving safety. Both ends of the steel wire rope 8 are wound around a hanging rod on the chassis 20, which is fixed to the underside of the chassis 20 for easy disassembly and maintenance by maintenance personnel.

[0032] The cassette 2 of this invention includes a first connecting strip 21 and a second connecting strip 22, which are connected to each other to form a placement area, into which the air cylinder body 1 is inserted. The cassette 2 of this invention is made of metal. To prevent breakage due to excessive bending, the first connecting strip 21 and the second connecting strip 22 are used to connect them, reducing the degree of bending and thus minimizing stress on the first and second connecting strips, thereby extending their service life.

[0033] The chassis 20 is equipped with a first fixing pin, and the first connecting belt 21 is bent and hooked onto the first fixing pin. The side of the first connecting belt 21 closest to the chassis 20 is bent and hooked onto the first fixing pin. The first fixing pin and the chassis 20 can be connected in a detachable manner, which is convenient for workers to disassemble and repair.

[0034] The chassis 20 is equipped with U-bolts 9, which are fastened to the chassis 20 by fasteners. The second connecting strap 22 is bent and hooked onto the U-bolts 9. The two ends of the U-bolts 6 are fastened to the chassis 20 by fasteners. The U-bolts 6 can bear the main gravity, so that the heavier air cylinder body 1 can be hooked onto the first connecting strap 21 and the second connecting strap 22.

[0035] The first connecting strap 21 and the second connecting strap 22 are connected by a connecting bracket 10. A first connecting rod 101 and a second connecting rod 102 are mounted side-by-side on the connecting bracket 10. The end of the first connecting strap 21 is fitted onto the outside of the first connecting rod 101, and the end of the second connecting strap 22 is fitted onto the outside of the second connecting rod 102. The first connecting rod 101 and the second connecting rod 102 can be connected via the connecting bracket 10. Furthermore, the first connecting rod 101 and the second connecting rod 102 are detachably mounted on the connecting bracket 10, facilitating subsequent maintenance and installation by personnel.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
