Description

Technical Field

[0001] This utility model relates to a hydraulic pipe replacement device for a crane hydraulic station, belonging to the technical field of hydraulic station auxiliary tools. Background Technology

[0002] In existing overhead crane hydraulic station systems, the inlet and outlet oil pipes from the hydraulic station's oil tank to the hydraulic pump often suffer from aging, peeling, cracks, oil leaks, and even bursts, leading to frequent maintenance. Furthermore, these pipes are directly connected to the pump body; disconnecting them causes oil leakage. Therefore, when replacing pipes or repairing the hydraulic pump, the hydraulic oil in the tank must be emptied first, and then refilled after the repair is complete. This process is not only time-consuming and labor-intensive but also significantly increases the workload for workers and reduces work efficiency. Additionally, the lack of protective devices during pipe replacement causes hydraulic oil to drip onto the ground, causing pollution. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a hydraulic station oil pipe replacement device for overhead cranes, which improves the convenience of replacing oil pipes and prevents oil dripping and pollution caused by pipeline replacement.

[0004] The present invention relates to a hydraulic station oil pipe replacement device for a crane, comprising: an oil distribution pipe including a main pipe, a plurality of branch pipes provided on the main pipe, valves provided on the branch pipes, and an external hydraulic pipeline connected to the outlet end of the valves;

[0005] A collection box for collecting oil is movably connected to the oil distribution pipe, and the collection box is located below the valve.

[0006] Furthermore, the collection box includes: a box body, a crossbeam on the box body, a slide cylinder on the crossbeam, and an oil drain port at the bottom of the box body;

[0007] The slide is slidably connected to the branch pipe, and the collection box moves on the branch pipe through the slide.

[0008] Furthermore, the bottom of the box is funnel-shaped, and the oil drain is located at the lowest point of the bottom of the box.

[0009] Furthermore, a reinforcing beam is provided on one side of the crossbeam to increase the connection strength between the crossbeam and the box body.

[0010] Furthermore, the collection box also includes hooks that are attached to the outer wall of the box.

[0011] Furthermore, a warning sign is provided on the collection box, and the warning sign is hung on a hook.

[0012] Furthermore, the warning signs are equipped with a reflective coating and contain warning slogans.

[0013] Furthermore, the valve type is a ball valve.

[0014] The advantages of this utility model compared with the prior art are:

[0015] The combination of oil pipes and valves provides multiple pathways when replacing hydraulic pipes in the hydraulic station, thus ensuring the continuity of the hydraulic station's operation; the collection box can effectively collect leaked oil during pipe replacement, preventing oil contamination and waste; the warning signs enhance safety awareness and improve safety during maintenance.

[0023] 4. Warning signs. Detailed Implementation

[0024] like Figures 1-3 As shown, this embodiment is achieved through the following technical solution: the oil distribution pipe 1 includes a main pipe 101, the main pipe 101 is provided with a plurality of branch pipes 102, the branch pipes 102 are provided with valves 2, and the outlet end of the valves 2 is connected to a hydraulic pipeline.

[0025] A collection box 3 for collecting oil is movably connected to the oil distribution pipe 1, and the collection box 3 is located below the valve 2.

[0026] Specifically, the collection box 3 includes: a box body 301, a crossbeam 302 on the box body 301, a slide cylinder 303 on the crossbeam 302, and an oil drain port 304 at the bottom of the box body 301;

[0027] The slide cylinder 303 is slidably connected to the branch pipe 102, and the collection box 3 moves on the branch pipe 102 through the slide cylinder 303.

[0028] Specifically, the bottom of the box 301 is funnel-shaped, and the oil drain port 304 is located at the lowest point of the bottom of the box 301; a plug is provided on the oil drain port 304.

[0029] Specifically, a reinforcing beam 3021 is provided on one side of the crossbeam 302 to increase the connection strength between the crossbeam 302 and the box 301.

[0030] Specifically, the collection box 3 also includes a hook 305, which is attached to the outer wall of the box body 301.

[0031] Specifically, a warning sign 4 is provided on the collection box 3, and the warning sign 4 is hung on the hook 305.

[0032] Specifically, warning sign 4 has a reflective coating and contains warning slogans.

[0033] Specifically, valve type 2 is a ball valve.

[0034] The specific working principle of this utility model is as follows:

[0035] In this embodiment, the oil distribution pipe 1 is provided with two branch pipes 102. Conventionally, the valve 2 on one branch pipe 102 is in the closed state and serves as a backup pipeline; the valve 2 on the other branch pipe 102 is in the open state and serves as the commonly used working pipeline. When the commonly used pipeline fails, the valve 2 of that pipeline is closed and the valve 2 of the backup pipeline is opened, thereby ensuring that the hydraulic station can work continuously.

[0036] When replacing the oil pipe, the operator first slides the collection box 3 via the slide cylinder 303 to the valve 2 corresponding to the oil pipe to be replaced. Then, the valve 2 is closed and the oil pipe is disassembled. At this time, the leaking oil will be effectively collected by the collection box 3. After the oil pipe replacement is completed, the drain port 304 is opened to drain the collected oil for further processing. Meanwhile, the reflective coating and warning signs on the warning sign 4 can remind the operator to pay attention to safety and avoid accidents.

[0037] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
