Description

Technical Field

[0001] This utility model relates to the field of mechanical auxiliary tools, specifically a locomotive obstacle removal and assembly device. Background Technology

[0002] Locomotives are widely used in railway transportation. Their obstacle clearers, installed at the lower ends of the car body, are used to remove obstacles in front of the locomotive, playing a crucial role in ensuring its safe operation. During locomotive maintenance, the obstacle clearers need to be disassembled. However, due to temperature imbalances during the manufacturing process and stress concentration at bending points, the release of stress during disassembly causes slight deformation, resulting in the mounting holes between the obstacle clearer and the car body becoming non-coaxial.

[0003] When the ground wheels of locomotive 9 move between the two sections of rail 8 on the foundation 7, adjustments are required.

[0004] Currently, the existing operation method for disassembling and assembling the HXD3 locomotive obstacle remover requires the use of surrounding walls 10 for support, and multiple people working together using tools such as wooden blocks 11 and hydraulic jacks 2 to press the obstacle remover to complete the disassembly and assembly. This operation method has many drawbacks: First, it is labor-intensive, requiring five to seven people to work together, consuming a lot of manpower; second, it is inefficient, with the disassembly and assembly of a single obstacle remover taking up to 4 hours; third, the equipment does not meet standardized operation requirements, making it difficult to guarantee the quality of the work; fourth, it poses safety hazards, as the operation relies on fixed objects such as surrounding walls, and falling parts may cause personal injury; fifth, it is highly dependent on the working environment, and the working site is very limited.

[0005] Therefore, there is an urgent need to design a special device to solve the above-mentioned problems in the disassembly and assembly of locomotive obstacle removers. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a locomotive obstacle removal device assembly and disassembly equipment.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A locomotive obstacle removal device includes a main frame, one side of which is inserted from the gap between the foundation and the locomotive until it passes over the rail, and a rail hook is detachably installed on the side of the main frame that passes over the rail.

[0009] Adjust the track hooks to a horizontal position when inserting the main frame;

[0010] When the end of the main frame passes the rail, adjust the rail hook to a vertical position, and lock the rail hook on the side of the rail away from the main frame;

[0011] The main frame is fixed with a hydraulic jack on the side away from the rail hook, which presses the locomotive horizontally toward the rail hook.

[0012] Preferably, the rail hook has a hook groove corresponding to the protrusion of the rail, the hook groove is engaged with the protrusion of the rail, and the hook groove and the protrusion of the rail are used in conjunction.

[0013] Preferably, four rectangular casters are fixedly installed at the bottom of the main frame, and each caster is equipped with a brake pad.

[0014] Preferably, a handle frame is detachably installed on the main frame, and a handle sleeve is fixedly fitted onto the handle of the handle frame.

[0015] Preferably, the main frame and the track hook are connected together by several bolts, and the track hook is a steel component.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses a hydraulic jack to adjust the position of the locomotive wheels by pressing the locomotive horizontally toward the rail hook, since the rail hook is locked on the side of the rail away from the main frame.

[0018] 2. Through practical application and testing, this utility model has shown that after using this equipment, the time required for disassembling and assembling a single obstacle remover has been reduced from 4 hours to 45 minutes, which has greatly improved work efficiency, significantly shortened locomotive maintenance downtime, and ensured transportation production efficiency.

[0019] 3. The equipment uses rail hooks to attach to steel rails as fixed points, eliminating dependence on the working environment and avoiding potential safety risks caused by relying on unstable supports such as surrounding walls. At the same time, the equipment's structural design is reasonable, and all components are securely installed, completely eliminating the safety hazards of falling parts causing personal injury that occurred in previous operations, thus protecting the safety of workers.

[0020] 4. The use of this equipment makes the disassembly and assembly of the obstacle clearer more standardized, meets the requirements of standardized operation, and effectively ensures the quality of locomotive maintenance.

[0021] 5. After the equipment was put into use, the requirements for the working environment were further reduced, the shunting operations in the depot were reduced, and the production order of the entire section was ensured. Attached Figure Description

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example

[0030] like Figure 1-4 As shown, a locomotive obstacle removal device includes a main frame 1. One side of the main frame 1 is inserted from the gap between the foundation and the locomotive until it passes over the rail. A rail hook 3 is detachably installed on the side of the main frame 1 that passes over the rail.

[0031] When inserting the main frame 1, adjust the track hook 3 to a horizontal position;

[0032] When the end of the main frame 1 passes the rail, the rail hook 3 is adjusted to a vertical position and the rail hook 3 is locked on the side of the rail away from the main frame 1.

[0033] A hydraulic jack 2 is fixed on the side of the main frame 1 away from the rail hook 3, which presses the locomotive horizontally toward the rail hook 3.

[0034] This utility model, by activating the hydraulic jack 2, allows the rail hook 3 to be engaged on the side of the rail away from the main frame 1, thus enabling the hydraulic jack 2 to compress the locomotive to move horizontally toward the rail hook 3, thereby achieving the adjustment of the position of the wheels on the locomotive;

[0035] The rail hook 3 has a hook groove 4 corresponding to the protrusion of the rail. The hook groove 4 is engaged with the protrusion of the rail.

[0036] This utility model, by opening a hook groove 4 on the track hook 3 that corresponds to the protrusion of the rail, can more stably lock the track hook 3 into the protrusion of the rail and prevent the track hook 3 from slipping off.

[0037] Four rectangular casters 5 are fixedly installed at the bottom of the main frame 1, and each caster 5 is equipped with a brake pad.

[0038] A handle frame 6 is detachably installed on the main frame 1, and a handle sleeve is fixedly fitted to the handle of the handle frame 6.

[0039] The main frame 1 and the track hook 3 are connected together by several bolts, and the track hook 3 is a steel component.

[0040] The main frame 1 supports the hydraulic jack 2, and together with the rail hook 3, it completes the position change of the force application point, making disassembly and assembly possible;

[0041] This part is made of angle steel and channel steel by welding. Based on the distance between the outer side of the obstacle remover and the inner side of the rail 8, the overall length of the main frame 1 is about 1270mm, the width is about 505mm, and the height is about 420mm.

[0042] The main frame 1 includes a structural frame, jack baffles, and tie rods; the materials used for its main structure are as follows:

[0043] Structural frame: Made of No. 4 hot-rolled equal angle steel Made by welding, it is sturdy and durable.

[0044] Jack baffle: Made of 14a hot-rolled channel steel As the support surface for the jack, the bottom is welded to a crossbeam (which is also made of 14a hot-rolled channel steel and welded to the structural frame), and the top is supported by No. 10 hot-rolled channel steel. It is welded to the structural frame.

[0045] Tie rod: also made of No. 10 hot-rolled channel steel It is welded to the bottom crossbeam of the structural frame and the structural frame. There are two tie rods in total, with a center-to-center distance of 330mm.

[0046] Handle 6 is mainly used for gripping and directional control during the disassembly and assembly of equipment. It is made of Φ26×2 cold-drawn seamless steel pipe (GB / T 8162-1999) welded together. The horizontal tube is 800mm long and has handles at both ends. The vertical tube is 1000mm long and spaced 550mm apart.

[0047] The rail hook 3 is a key element for the effective implementation of the solution. It is installed at the end of the main frame tie rod. After being adjusted to a vertical position, its notch can be engaged with the inside of the rail head, transferring the force transmitted from the tie rod to the rail that is attached to the locomotive. This completely eliminates the dependence on the surrounding environment during operation, and there is no need to rely on walls or other fixed objects.

[0048] The rail hook 3 is made of hot-rolled steel plate with a nominal thickness of 10mm (GB / T 709-2006), which is 240mm long, 75mm high and 10mm thick, and has a notch at the far end to achieve attachment with the rail.

[0049] Make a 55×40mm notch at the front end of the steel plate. Before operation, adjust the bolt installation position so that the rail hook is perpendicular to the tie rod and is attached to the inside of the rail head.

[0050] The dismantling and assembly equipment is equipped with a 16-ton screw jack, which can effectively align the installation holes to facilitate bolt removal. It can also be used with other jacks of different sizes to meet different pressure and lifting force requirements when dismantling and assembling the obstacle remover.

[0051] To improve the flexibility of the disassembly and assembly trolley, four swivel wheels (with locking rear wheels) were added to the design of the disassembly and assembly equipment to ensure that the equipment is easy to maneuver and highly flexible when used on site, and to facilitate relocation and use in different lines and warehouses.

[0052] Since the equipment was put into use in June 2016, it has completed the disassembly and assembly of 47 units, totaling 94 C4 locomotive troubleshooters. The number of operators has been reduced from 5 to 2, and the time required for disassembly and assembly of a single unit has been shortened from 4 hours to 45 minutes, saving a total of 916 man-hours and improving 5,820 man-hours, which has greatly reduced labor costs.

[0053] After the specialized dismantling and assembly equipment was put into use, it significantly shortened locomotive maintenance downtime, ensured the quality of locomotive maintenance, and improved transportation production efficiency. At the same time, it avoided the personal injury risks associated with previous operating methods, protecting the safety of workers. Furthermore, the equipment further reduced the requirements for the working environment, decreased shunting operations within the depot, and ensured the overall production order of the entire section.

[0054] The design and manufacturing scheme of this locomotive obstacle removal device is economical and practical, with low cost, high output, and significant comprehensive benefits. It solves the on-site operation problem in a relatively simple way. Most importantly, the successful development and deployment of this equipment has completely changed the status quo of having no dedicated equipment for locomotive obstacle removal. It meets the development needs of railway locomotive equipment exploration and innovation, and also meets the requirements of the "Guiding Opinions of China Railway Corporation on the Configuration of Maintenance Tooling and Equipment for Harmony Locomotives C4 and Below". It creates conditions for further upgrading and improving the HXD3 locomotive obstacle removal device and provides ideas for further expanding on-site operation methods.

[0055] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
