Description
Technical Field
[0001] The utility model relates to the technical field of oil depot oil distribution equipment, in particular to a maintenance trolley for a crane pipe installed under the oil depot. Background Art
[0002] Daily inspection and maintenance of oil depot oil distribution equipment is a very important part of oil depot safety production. Inspection and maintenance operations involve not only safety risks but also environmental risks. Bottom-mounted crane pipes are common oil transmission equipment in oil depots. Due to the particularity of the working environment, bottom-mounted crane pipes often face problems such as corrosion and wear, resulting in performance degradation or even failure. Therefore, the repair and maintenance of bottom-mounted crane pipes is particularly important, and the dry valve on the bottom-mounted crane pipe needs to be replaced in time after it is damaged.
[0003] In the prior art, the oil in the crane pipe under the oil platform can only be emptied by placing the oil into an aluminum basin through a lock control, which easily causes oil splashing, polluting the environment and increasing the loss of oil. The dry valve (also known as the API joint dry separation valve) needs to be replaced, but it is impossible to detect whether the sealing performance of the new dry valve is good. If the seal is not tight and leakage occurs when the dry valve is replaced, it is easy to cause repeated emptying and secondary maintenance and replacement of the crane pipe under the oil depot, which not only wastes manpower time but also increases the safety and environmental risks on site. Therefore, we propose a maintenance trolley for the crane pipe under the oil depot to solve the above problems. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and provides a small maintenance cart for a crane pipe installed under an oil depot.

[0012] Compared with the prior art, the advantages of the utility model are:
[0013] This solution connects the oil unloading valve with the lower loading valve of the crane pipe. The oil hose in the lower loading crane pipe guides the oil into the aluminum basin of the collection container, which greatly avoids oil splashing.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Depend on Figure 1-Figure 3 As shown, it involves a maintenance trolley for crane pipes installed under an oil depot, comprising a base plate 1, the base plate 1 is made of steel plate, four self-locking wheels 2 are fixedly installed on the bottom of the base plate 1, the self-locking wheels 2 drive the base plate 1 to move and limit, the top of the base plate 1 is fixedly connected to a bearing tray 3, the top of the bearing tray 3 is fixedly connected to a pillar 4, the outer wall of the pillar 4 is fixedly connected to a plurality of support plates 5, the bottoms of the plurality of support plates 5 are all fixedly connected to the top of the bearing tray 3, and the pillars 4 and the support plates 5 support the crane pipe rotating joint 6.
[0021] The top of the pillar 4 is fixedly connected with a crane pipe rotating joint 6, one end of the crane pipe rotating joint 6 is fixedly connected with a flange 7, the outer wall of the flange 7 is fixedly connected with an oil unloading valve 8, the oil unloading valve 8 is fixed to one end of the crane pipe rotating joint 6 through the flange 7, and the dry valve and the oil unloading valve 8 are directly connected by a card sleeve type connection. As long as the oil-generating lower crane pipe is connected, the yin and yang joints can be tightly locked together, and the connection is convenient and fast, which greatly improves the work efficiency; because the yin and yang joints of the lower crane pipe dry valve connection device are opened and closed synchronously, and in the whole process before disconnection, there is no gap between the opening and closing plug on the female joint and the sealing plug on the male joint, and there is a plane contact between the yin and yang joints, so there is no residual medium when disconnected, which truly realizes the environmental protection requirements.
[0022] An electrostatic releaser 9 is installed on the top of the oil unloading valve 8. The electrostatic releaser 9 uses a SA-M electrostatic grounding alarm, an intrinsically safe explosion-proof electrical device, with good alarm performance, and uses reliable integrated circuits. The anti-static and alarm performance are stable and reliable; when working, the paint-breaking needle, the clamp, and the wire are effectively connected to the grounding pile to form an equipotential between the connected equipment and the earth, and static electricity is introduced into the earth to ensure that the electrostatic grounding loop resistance of the equipment meets the safety standards. When one side of the clamp has poor contact, an alarm response is immediately made to remind the staff; the alarm module is fixed to the outside of the toolbox 17, the grounding terminal is connected to the base plate 1, and the grounding clamp for detecting the connection equipment loop is wrapped around the U-shaped handrail 14.
[0023] The other end of the crane pipe rotary joint 6 is fixedly connected with a manual ball valve 10. The manual ball valve 10 is in a closed state when the dry valve female joint is first connected to the oil unloading valve 8, and the other end of the dry valve is connected to the existing water hose, and water is delivered through the existing pump body. The outer wall of the manual ball valve 10 is fixedly connected with a hose 11.
[0024] A pushing mechanism is provided on the top of the base plate 1, and the pushing mechanism includes a U-shaped handrail 14. Four trapezoidal pieces 12 are fixedly connected to the top of the base plate 1, and the same shaft body 13 is fixedly connected between two trapezoidal pieces 12. The outer walls of the two shaft bodies 13 are fixedly connected to the two ends of the U-shaped handrail 14. Two cross bars 15 are fixedly connected to the outer wall of the U-shaped handrail 14, and a plurality of vertical bars 16 are fixedly connected between the two cross bars 15. A tool box 17 is welded to the outer wall of the U-shaped handrail 14. The tool box 17 can store commonly used tools such as wrenches and sockets. Not only can the required tools be found quickly during maintenance, but they can also be conveniently summarized and stored after use, and are not easy to lose.
[0025] Working principle: When in use, when the oil in the crane pipe under the oil platform is emptied, the bottom plate 1 is moved through the four self-locking wheels 2 and the U-shaped handrail 14 to connect the oil unloading valve 8 with the crane pipe lower valve, similar to the connection with the tanker when filling oil. The oil in the lower crane pipe is diverted from the oil unloading valve 8, the crane pipe rotary joint 6 and the hose 11 to the collection container aluminum basin by manually turning the manual ball valve 10, which greatly avoids oil splashing; the dry valve female connector that needs to be installed can be connected to the oil unloading valve 8 first, and the other end of the dry valve can be connected to the existing water hose. Water is passed to test the sealing performance of the dry valve, which can quickly test whether the sealing is good. After the dry valve is installed once after the test, it not only avoids the loss caused by oil leakage, but also reduces the safety and environmental risks on site.
