Technical Field

[0001] This utility model belongs to the technical field of railway sleeper production equipment, specifically relating to a rail pre-embedded sleeve oil injection and capping device. Background Technology

[0002] During the railway sleeper production process, to ensure the stability of sleeper quality, grease needs to be injected into the sleeper sleeve after demolding, and then the sleeve cap needs to be fastened to prevent rusting during subsequent storage. Currently, the grease injection and capping operations for the pre-embedded rail sleeves are mostly done manually, which is inefficient and makes it difficult to ensure consistency in the amount of grease injected and the quality of the capping. Problems such as insufficient or excessive grease injection and loose capping are prone to occur, affecting the quality of the sleepers and production efficiency.

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art are within the protection scope of this utility model.

They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0028] like Figure 1-3 As shown, a rail-embedded sleeve oil injection and capping device includes a robotic arm 2 and a capping mechanism. The robotic arm 2 is a commercially available six-axis robotic arm 2. The structure and electrical control principle of the robotic arm 2 will not be described in detail here.

[0029] The sleeper sleeve cover 12 is generally a metal or plastic cover structure with a flat top surface, which can be picked up and put down by a suction cup structure. The cover-fastening mechanism is used to pick up and put down the sleeper sleeve cover. The cover-fastening mechanism is assembled at the end of the robotic arm 2. The working radius of the robotic arm 2 covers the sleeper sleeve cover 12 feeding fixture and the sleeper sleeve cover fastening station. Thus, under the drive of the robotic arm 2, the sleeper sleeve cover 12 can be picked up by the sleeper sleeve cover 12 feeding fixture, and then the sleeper sleeve cover 12 can be fastened to the corresponding position of the sleeper mold at the sleeper sleeve cover fastening station.

[0030] The cover-fastening mechanism includes a main body 4 and an oiler 8. The oiler 8 is a commercially available product. The main body 4 has a downward-extending negative pressure pipe 5 in the middle. The upper end of the negative pressure pipe 5 is connected to a negative pressure pump to draw oil into the sleeper sleeve cover 12 through negative pressure. The diameter of the negative pressure pipe 5 is smaller than the diameter of the sleeper sleeve cover 12. The oiler 8 is located on the side of the main body 4 and is connected to an oil pump. Its oil injection pipe extends downward to inject oil into the sleeper sleeve.

[0031] In this embodiment, the diameter of the oil injection pipe is smaller than that of the sleeper sleeve, so that it can be inserted into the sleeper sleeve for oil injection. The oil injector 8 is slidably mounted on the main body 4 along the longitudinal direction via the slide seat 9. The main body 4 is a square box, and a slide rail corresponding to the slide seat 9 is provided on the main body 4. A driving device corresponding to the slide seat 9 is provided on the main body 4. The driving device can be a cylinder or a hydraulic cylinder. No specific restrictions are placed on its structure here. Under the drive of the driving device, the oil injection pipe can slide downward to extend below the negative pressure pipe 5, thereby avoiding the negative pressure pipe 5 from contacting the sleeper mold during the oil injection process.

[0032] In an optional embodiment, the lower end of the negative pressure pipe 5 is provided with an elastic suction nozzle 6. The negative pressure pipe 5 serves as the supporting body 4 to ensure that the elastic suction nozzle 6 will not undergo excessive deformation. The elastic suction nozzle 6 can be made of rubber. The upper end of the elastic suction nozzle 6 is closed and connected to the inner wall of the negative pressure pipe 5, or the upper end is closed and directly connected to the negative pressure pipe 5. The lower end of the elastic suction nozzle 6 extends out of the negative pressure pipe 5 and has a flat lower end surface, so that it can be sealed after contacting the sleeper sleeve cover 12 to meet the suction requirements.

[0033] Furthermore, a suction cup-shaped or trumpet-shaped suction port is provided at the lower end of the elastic suction nozzle 6 to ensure suction stability.

[0034] In this embodiment, the main body 4 of the elastic suction nozzle 6 is a cylindrical rubber tube. During the suction process, it can be pressed against the sleeper sleeve cover 12 to improve suction stability and avoid damaging the sleeper sleeve cover 12.

[0035] Furthermore, the portion of the elastic suction nozzle 6 extending out of the negative pressure tube 5 is provided with a baffle 7 corresponding to the negative pressure tube 5. The baffle 7 can limit the maximum upward retraction distance of the elastic suction nozzle 6, thereby blocking the elastic suction nozzle 6 and maximizing the suction effect while ensuring sufficient buffer spacing.

[0036] In an optional embodiment, the sleeper sleeve cover 12 feeding fixture includes a vibrating feeding plate 3 and a feeding trough 10. The vibrating feeding plate 3 is a conventional product, and no modifications or excessive restrictions are made to it. The feeding trough 10 is connected to the upper end of the feeding track inside the vibrating feeding plate 3. The feeding trough 10 extends horizontally along the tangent direction of the feeding track, so that the sleeper sleeve cover 12 transmitted upward by the vibrating feeding plate 3 can be stably placed. The trough body of the feeding trough 10 is adapted to the sleeper sleeve cover 12. The end away from the feeding track is a closed end, which is used to stop the sleeper sleeve cover 12 and prevent it from falling out. There are corresponding rail stops 13 on both sides above the feeding trough 10. The rail stops restrict the sleeper sleeve cover 12. The front end of the rail stops 13 is provided with a notch corresponding to the sleeper sleeve cover 12. The negative pressure pipe 5 is used to suck up the sleeper sleeve cover 12 at this point.

[0037] Furthermore, in this application, the distance between the lower end face of the elastic suction nozzle 6 and the baffle 7 is adapted to the depth of the sleeper sleeve cover 12. The inner cavity of the sleeper sleeve cover 12 also has a flat inner wall (at least one side of the inner wall of the sleeper sleeve cover 12 is flat). The diameter of the elastic suction nozzle 6 is smaller than the inner cavity diameter of the sleeper sleeve cover 12 to avoid friction between the two. This allows it to be inserted into the sleeper sleeve cover 12 and sucked tightly against the inner wall of the sleeper sleeve cover 12. As a result, the vibrating feeding plate 3 does not need to consider whether it is facing upwards during the feeding process. Therefore, the vibrating feeding plate 3 does not need to be equipped with a sleeper sleeve cover 12 orientation adjustment mechanism, thereby reducing the structural complexity of the vibrating feeding plate 3.

[0038] The baffle 7 is also made of rubber, and its diameter is larger than that of the sleeper sleeve cover 12. Its lower surface is flat. The baffle 7 can also seal the opening end of the sleeper sleeve cover 12 by contacting it, thus achieving a double seal and ensuring the suction effect.

[0039] In addition, the lower diameter of the flexible suction nozzle 6 is smaller than the diameter of the sleeper sleeve. An air pump is connected to the flexible suction nozzle 6 through an electronically controlled valve, so as to control the air flow direction of the flexible suction nozzle 6. Before oil injection, the flexible suction nozzle 6 is inserted into the sleeper sleeve and blows air, thereby blowing out the dust inside the sleeper sleeve.

[0040] The vibrating feeding plate 3 has a spiral feeding track inside. At the upper end of the feeding track, there is a guide plate 11 corresponding to the feeding trough 10. The distance between the guide plate 11 and the end of the feeding track is adapted to the sleeper sleeve cover 12, thereby ensuring that the sleeper sleeve cover 12 can smoothly enter the feeding trough 10.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
