Description

Technical Field

[0001] The utility model relates to the technical field of loading arms, and more specifically, to a liquid receiving mechanism of a loading arm. Background Art

[0002] A loading arm is a telescopic and movable pipe, which is mostly used for the loading and unloading of liquid materials such as oil and chemicals. The media in the pipe are such as oil and water. It is divided into various types, and the loading operation of the loading arm is an essential process.

[0003] Every time the factory area ships and loads goods, a loading arm is used to transport the product into the tank car. After each loading is completed and the pump and valve are closed, there will still be residual product in the vertical pipe of the loading arm. Due to inertia, the residual product will drip along the vertical pipe of the loading arm. At this time, it is necessary for workers to wait for most of the residual product to enter the tank car and then add a bucket to the vertical pipe for collection and treatment. When workers operate the loading arm on the top of the tank car, they may encounter acids, alkalis and other media that are toxic and harmful to the human body, which is extremely dangerous, and residual liquid may also drip during the actual operation process.

[0023] Refer to Figures 1-3 As shown, it is a preferred embodiment provided by the present utility model.

[0024] The liquid receiving mechanism of the loading arm includes a vertically movable vertical pipe 10 and a liquid receiving hopper 20. The vertical pipe 10 is connected to the liquid receiving hopper 20 through a rotating mechanism 30. The rotating mechanism 30 includes a connecting plate 31 and a rotating motor 32. The rotating motor 32 is installed on the connecting plate 31. The connecting plate 31 is connected to the vertical pipe 10. The rotating motor 32 is connected to a telescopic motor 40. The telescopic motor 40 is connected to the liquid receiving hopper 20. The liquid receiving hopper 20 includes an inner hopper 22 for receiving leaked liquid and an outer hopper 21 for placing the inner hopper 22. The outer hopper 21 is connected to the telescopic motor 40. The inner hopper 22 is detachably connected to the outer hopper 21.

[0025] The liquid receiving mechanism of the loading arm provided above uses the liquid receiving hopper 20 to receive the residual liquid leaking from the vertical pipe 10, preventing the residual liquid from dripping and splashing everywhere and damaging the environment. The vertical pipe 10 can drive the liquid receiving hopper 20 to rotate away from the vertical pipe 10 through the rotating mechanism 30, and then use the telescopic motor 40 to recycle it, preventing the liquid receiving hopper 20 from affecting the insertion of the vertical pipe 10 into the tank car, solving the problem that part of the material residual liquid is likely to leak out after the loading arm finishes loading; the liquid receiving hopper 20 receives the leaked liquid through the inner hopper 22 and places the inner hopper 22 through the outer hopper 21, facilitating the removal and pouring out of the residual liquid from the inner hopper 22.

[0026] In this embodiment, the inner hopper 22 has an internal cavity 23 with an open top. Hanging ears 24 are respectively arranged on both sides of the open top, and the two hanging ears 24 are connected by a connecting piece 25. In this way, the inner hopper 22 can be separated from the outer hopper 21 through the connecting piece 25, and the connecting piece 25 facilitates the lifting and placing function of the inner hopper 22.

[0027] In this embodiment, the connecting piece 25 is arranged in an arc shape. The two ends of the connecting piece 25 are respectively hinged to the hanging ears 24. When the connecting piece 25 swings to the edge of the open top, the connecting piece 25 extends along the length direction of the edge of the open top. In this way, when the residual liquid of the vertical pipe 10 drips, it will not drip onto the connecting piece 25, and the connecting piece 25 will not affect the collection of the residual liquid.

[0028] In this embodiment, the bottom of the telescopic motor 40 has a telescopic rod 41. The top of the telescopic rod 41 is inserted into the telescopic motor 40, and the bottom of the telescopic rod 41 is connected to the outer hopper 21. In this way, the telescopic motor 40 can drive the outer hopper 21 to move up and down telescopically through the telescopic rod 41.

[0029] In this embodiment, a horizontal plate 42 is connected to the telescopic motor 40. The horizontal plate 42 and the outer hopper 21 are arranged vertically opposite to each other. A guide rod 43 that can move up and down on the horizontal plate 42 is connected between the horizontal plate 42 and the outer hopper 21. The bottom of the guide rod 43 is fixedly connected to the outer hopper 21, the top of the guide rod 43 penetrates the horizontal plate 42, and the guide rod 43 and the telescopic rod 41 are arranged horizontally and relatively spaced apart.

[0030] The horizontal plate 42 increases the stability of the telescopic rod 41 driving the outer hopper 21 to move up and down telescopically through the guide rod 43, preventing the telescopic rod 41 from swinging or deviating during the process of driving the outer hopper 21 to move up and down.

[0031] In this embodiment, a sealing cap 50 that moves up and down on the vertical pipe 10 is arranged on the vertical pipe 10. The sealing cap 50 is arranged around the outer circumference of the vertical pipe 10. A spring mechanism 60 is arranged on the vertical pipe 10. The vertical pipe 10 is connected to the sealing cap 50 through the spring mechanism 60, and a sealing ring 70 that is squeezed and deformed is installed between the spring mechanism 60 and the sealing cap 50.

[0032] On the premise of ensuring that the sealing cap 50 seals the tank mouth of the tank truck, the sealing cap 50 reduces the impact force when the sealing cap 50 contacts the tank mouth of the tank truck during the descending process of the vertical pipe 10 during loading through the spring mechanism 60, so as to avoid the conflict between the up and down forces causing damage to the crane pipe or the tank truck. The sealing cap 50 reduces the influence of the tilt of the tank truck on the vertical pipe 10 during loading through the sealing ring 70; the problem that the conflict between the up and down forces in the process of the crane pipe driving the sealing cap 50 to seal can easily cause damage to the crane pipe or the tank truck is solved.

[0033] In this embodiment, the spring mechanism 60 includes a fixing ring 61 and a pressing ring 62. The fixing ring 61 is fixed around the outer periphery of the vertical tube 10. The fixing ring 61 is connected to the pressing ring 62 through a spring column 63. The pressing ring 62 and the sealing ring 70 are fixed to the sealing cap 50 through bolts. The interval between the fixing ring 61 and the pressing ring 62 forms a compression area for the spring column 63 to be compressed and deformed. A plurality of spring columns 63 are arranged at intervals around the circumference of the extending compression area.

[0034] In this way, when the sealing cap 50 is obstructed by the tank mouth of the tank truck, the sealing cap 50 will move in the opposite direction relative to the vertical pipe 10. The sealing cap 50 uses the elasticity of the spring column 63 to buffer the conflict between the sealing cap 50 and the force of the tank mouth moving up and down, thereby avoiding damage to the crane pipe or the tank truck.

[0035] When the tank truck starts to load, the vehicle sometimes tilts slightly as the amount of liquid loaded changes, and the sealing cap 50 tilts with the tank mouth. Since there is a gap between the pressure ring 62 and the vertical pipe 10, and the material of the sealing ring 70 is soft, the vertical pipe 10 will not move with the tilt of the vehicle while ensuring sealing.

[0036] In this embodiment, the drop tube 10 is connected to a lifting driver for driving the drop tube 10 to move up and down, and the lifting driver is electrically connected to a limit switch 80, which is installed on the drop tube 10, and the limit switch 80 is arranged longitudinally opposite to the sealing cap 50, and the limit switch 80 is located above the sealing cap 50. In this way, the drop tube 10 can be prevented from excessively extending into the tank opening of the tank truck, thereby preventing the drop tube 10 from damaging the tank truck.

[0037] In this embodiment, the limit switch 80 includes a switch seat 81 and a driving rod 82 that controls the lifting drive to stop driving the vertical tube 10 to move downward. One end of the driving rod 82 is hingedly mounted on the switch seat 81, and the switch seat 81 is mounted on the fixing ring 61. The other end of the driving rod 82 is mounted with a guide wheel 83, and the guide wheel 83 is exposed above the sealing cap 50.

[0038] The limit switch 80 contacts the sealing cap 50 through the guide wheel 83, which is used to reduce the frictional resistance between the drive rod 82 and the sealing cap 50. When the sealing cap 50 pushes the guide wheel 83 through an upward force, the drive rod 82 is driven by the guide wheel 83 to control the lifting driver to stop driving the vertical pipe 10 from moving downward.

[0039] In this embodiment, a ventilation pipe 90 is connected to the sealing cap 50, and the ventilation pipe 90 is longitudinally inserted on the top of the sealing cap 50. In this way, the excess gas in the tank car can be discharged through the ventilation pipe 90 in the tank opening of the tank car.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
