Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway crossing technology, and in particular to an inspection hole cover for preventing the traction motor of a diesel locomotive from detaching. Background Technology
[0002] A DC traction motor consists of a commutator and carbon brushes. After the motor has been running for a period of time, the carbon brushes need to be replaced. Therefore, an inspection hole is provided on the frame of the DC traction motor. These inspection holes are typically used to check the sealing condition of the inspection hole cover. When it is necessary to inspect the internal condition of the motor or replace the carbon brushes, the inspection hole cover needs to be opened.
[0003] Currently, the failure of the inspection hole cover of the traction motor to fall off during operation of diesel locomotives occurs frequently. In the course of use, it has been found that cracks in the upper hook of the inspection hole cover, detachment from welding, and failure of the spring clip can all easily cause the motor cover to fall off. On the one hand, the falling off of the traction motor cover can allow moisture, dust, and foreign objects to enter the motor, reducing the motor insulation and causing major mechanical accidents such as motor burnout. On the other hand, if the motor cover falls off and lands on the rail, it may cause a major safety hazard of train derailment. Utility Model Content
[0004] The purpose of this utility model is to solve the problem in the prior art where cracks in the upper hook of the inspection hole cover, detachment from welding, and failure of the spring clip can easily cause the motor cover and traction motor cover to fall off. This utility model provides an anti-detachment inspection hole cover for the traction motor of an internal combustion locomotive. It has both a fastening mechanism and a secondary protection structure for anti-detachment, which greatly improves the reliability of the inspection hole cover and effectively reduces the risk of the inspection hole cover falling off.
[0005] To achieve the above objectives, this utility model provides an anti-derailment inspection hole cover for the traction motor of an internal combustion locomotive, comprising a bracket, a buckle, a hook, and an anti-derailment connecting ring. The bracket and hook are fixed on the base, the buckle is installed on a plurality of inspection hole covers provided on the base, the anti-derailment connecting ring is installed on the inspection hole cover, and a connecting rope ring is connected between adjacent anti-derailment connecting rings. Each connecting rope ring is connected to the anti-derailment rope ring through a first locking clip, and the anti-derailment rope ring is connected to a fixed seat through a locking member. The fixed seat is installed on the locomotive.
[0006] As a further description of the above technical solution: the locking component includes a locking body, one end of which is rotatably connected to a locking rod, and the other end of the locking body is provided with a locking groove adapted to the locking rod, and a locking ring is threadedly connected to the locking rod.
[0007] As a further description of the above technical solution: the fixed base includes a base plate, the bottom of which is connected to a hanging rod, and the base plate is bolted to the locomotive.
[0008] As a further description of the above technical solution: both the connecting rope loop and the anti-detachment rope loop are made of steel wire rope.
[0009] As a further description of the above technical solution: the connecting rope ring and the anti-derailment rope ring are both formed by connecting the ends of a steel wire rope, and a second locking clip is provided at the connection point of the beginning and end of the connecting rope ring and the anti-derailment rope ring.
[0010] As a further description of the above technical solution: the diameter of both the connecting rope loop and the anti-slip rope loop is 5mm.
[0011] As a further description of the above technical solution: at least two anti-detachment connecting rings are installed on each of the observation hole covers.
[0012] As a further description of the above technical solution: the base is provided with four observation hole covers.
[0013] The above technical solution has the following advantages or beneficial effects:
[0014] This invention uses a snap fastener to secure the inspection port cover to the machine base. When issues arise, such as hook cracks, weld failure, or spring clip malfunction, causing the inspection port cover to tend to fall off, the anti-detachment structure, composed of a connecting rope ring and an anti-detachment rope ring, comes into play. The connecting rope ring connects to the anti-detachment connecting rings on adjacent inspection port covers, forming a unified constraint network. The anti-detachment rope ring is connected to the fixing base via a locking component, securing the entire inspection port cover system to the locomotive and preventing the inspection port cover from falling off. With both the snap fastener fixation and the secondary protection of the anti-detachment connecting structure, the reliability of the inspection port cover's anti-detachment function is greatly improved, effectively reducing the risk of the inspection port cover falling off.

[0024] like Figure 1-4 As shown, the present invention provides an anti-derailment inspection hole cover for a traction motor of an internal combustion locomotive, comprising a bracket 1, a buckle 2, a hook 3, and an anti-derailment connecting ring 4. The bracket 1 and the hook 3 are fixed on the base 5. The buckle 2 is installed on multiple inspection hole covers 6 provided on the base 5. The anti-derailment connecting ring 4 is installed on the inspection hole cover 6. A connecting rope ring 7 is connected between adjacent anti-derailment connecting rings 4. Each connecting rope ring 7 is connected to an anti-derailment rope ring 9 through a first locking clip 8. The anti-derailment rope ring 9 is connected to a fixed seat 11 through a fastening member 10. The fixed seat 11 is installed on the locomotive.
[0025] In the technical solution of this invention, the observation hole cover 6 is fixed to the base 5 by the buckle 2. When the hook cracks, the weld breaks, or the spring clip fails, causing the observation hole cover 6 to tend to fall off, the anti-detachment structure composed of the connecting rope ring 7 and the anti-detachment rope ring 9 comes into play. The connecting rope ring 7 connects to the anti-detachment connecting ring 4 on the adjacent observation hole cover 6, forming an integral constraint network. The anti-detachment rope ring 9 is connected to the fixing seat 11 through the locking member 10, fixing the entire observation hole cover system to the locomotive and preventing the observation hole cover from falling off. With both the fixing of the buckle 2 and the secondary protection of the anti-detachment connecting structure, the reliability of the observation hole cover's anti-detachment is greatly improved, and the risk of the inspection hole cover falling off is effectively reduced.
[0026] Specifically, multiple observation hole covers are connected into a single unit via connecting rope loops 7, enhancing system stability. Even if the buckle of one observation hole cover malfunctions, the other observation hole covers can still restrain it, preventing it from falling off independently. The connecting rope loops 7 are installed on the anti-detachment connecting rings 4 of the observation hole covers 6, and adjacent anti-detachment connecting rings 4 are connected by connecting rope loops 7. Each connecting rope loop 7 is connected to an anti-detachment rope loop 9 via a first locking clip 8. The anti-detachment rope loop 9 is connected to the fixing base 11 via a locking member 10.
[0027] Each observation hole cover 6 is equipped with at least two anti-detachment connecting rings 4, and the diameter of the connecting rope ring 7 and the anti-detachment rope ring 9 is 5mm.
[0028] like Figure 2 and Figure 3 As shown, the locking component 10 includes a locking body 101. One end of the locking body 101 is rotatably connected to a locking rod 102, and the other end of the locking body 101 is provided with a locking groove 103 that is adapted to the locking rod 102. A locking ring 104 is threadedly connected to the locking rod 102. By rotating the locking rod 102 into the locking groove 103 and tightening the locking ring 104, the secure connection and easy disassembly of the anti-detachment rope ring 9 and the fixing seat 11 are achieved.
[0029] like Figure 1 and Figure 4 As shown, the fixed base 11 includes a base plate 111, with a hanging rod 112 connected to the bottom of the base plate 111. The base plate 111 is mounted on the locomotive by bolts 113. The fixed base 11 is mounted on the locomotive by bolts 113. The locking member 10 makes the connection and disassembly of the anti-derailment rope ring 9 to the fixed base 11 simple, which facilitates the installation, maintenance and repair of the device. The bolts 113 facilitate the installation and disassembly of the base plate 111.
[0030] like Figure 1 and Figure 4As shown, both the connecting rope ring 7 and the anti-derailment rope ring 9 are made of steel wire rope. The connecting rope ring 7 and the anti-derailment rope ring 9 are made of steel wire rope and are connected and fixed by components such as locking clips and fastening devices, ensuring the strength and durability of the anti-derailment structure and enabling it to adapt to complex working conditions such as vibrations during locomotive operation.
[0031] like Figure 1 As shown, both the connecting rope ring 7 and the anti-derailment rope ring 9 are formed by connecting the ends of a steel wire rope. A second locking clip 12 is provided at the connection point of both the connecting rope ring 7 and the anti-derailment rope ring 9. The connection is formed by connecting the ends of a steel wire rope, and the second locking clip 12 is provided at the connection point of both ends to ensure the firmness and reliability of the connection, while also facilitating the installation and disassembly of the connecting rope ring 7 and the anti-derailment rope ring 9.
[0032] The base 5 is equipped with four observation hole covers 6, which are located on the upper part, lower part, front and back of the base 5, respectively.
[0033] Working principle: The inspection hole cover 6 is fixed to the base 5 by the hook 2. When the hook cracks, becomes detached, or the spring clip fails, causing the inspection hole cover 6 to tend to fall off, the anti-detachment structure composed of the connecting rope ring 7 and the anti-detachment rope ring 9 comes into play. The connecting rope ring 7 connects to the anti-detachment connecting ring 4 on the adjacent inspection hole cover 6, forming an integrated restraint network. The anti-detachment rope ring 9 is connected to the fixing seat 11 through the locking member 10, fixing the entire inspection hole cover system to the locomotive and preventing the inspection hole cover from falling off. With the fixing of the hook 2 and the secondary protection of the anti-detachment connecting structure, the reliability of the inspection hole cover's anti-detachment is greatly improved, effectively reducing the risk of the inspection hole cover falling off.
