Description

Technical Field

[0001] This invention relates to the field of material loading and unloading technology, specifically to an automatic loading arm for automobiles. Background Technology

[0002] Loading arms are specialized equipment used in the petrochemical industry for loading and unloading fluids. Also known as fluid loading arms, they are mobile devices that use rotary joints to connect with rigid pipes and elbows to transfer liquid media between trains, tank cars, and storage and transportation pipelines on trestle bridges. They are characterized by high safety, flexibility, and long service life.

[0003] The existing loading arms require manual connection between the loading arms and the loading / unloading vehicles, which is cumbersome. Furthermore, the loading arms are not cleaned after loading, and the oil adhering to them is exposed to the air for a long time, which can easily dry and solidify on the surface of the loading arms. This can cause the oil to fall into the oil during the next loading, reducing the quality of the oil and corroding the loading arms over time. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic loading arm for automobiles to solve the problems mentioned in the background art.

[0007] The equipment bracket is installed on the side of the loading and unloading bracket, and the equipment bracket is used to support the equipment components;

[0008] The loading and unloading assembly includes a hydraulic adjustment mechanism, a pipeline cleaning mechanism, and a loading and unloading mechanism. The hydraulic adjustment mechanism adjusts the position of the loading and unloading mechanism, and the pipeline cleaning mechanism cleans the pipeline of the loading and unloading mechanism.

[0009] The equipment components include a feed pipe, an electric ball valve, an electromagnetic flow meter, a manual gate valve, and an electrical control box.

[0010] Preferably, the loading and unloading bracket includes a support frame, and support columns are provided at the four corners below the support frame. The support columns are fixed to the support frame by U-bolts.

[0011] Preferably, the hydraulic adjustment mechanism includes a first hydraulic cylinder, a rectangular frame, and a loading / unloading platform. The inner walls of the rectangular frame and the support frame are provided with sliding grooves. Pulleys are provided on both sides of the rectangular frame and the loading / unloading platform. The loading / unloading platform is located inside the rectangular frame. The pulleys are in rolling connection with the sliding grooves. There are two first hydraulic cylinders. The cylinder bodies of the two first hydraulic cylinders are fixedly connected to the support frame, and the two first hydraulic cylinders are set at 90° to each other. The hydraulic rod ends of the two first hydraulic cylinders are fixedly connected to the side of the rectangular frame and the upper surface of the loading / unloading platform, respectively.

[0012] Preferably, the loading and unloading mechanism includes a housing, a composite hose, a tee pipe, a second hydraulic cylinder, and a loading pipe. A sealing plate is welded to the upper end of the loading pipe. The tee pipe is sleeved on the surface of the loading pipe, and the other end of the tee pipe is connected to the composite hose. An inlet is provided at the upper end of the loading pipe corresponding to the connection between the tee pipe and the composite hose. The cylinder body of the second hydraulic cylinder is fixedly installed on the loading and unloading platform, and the end of its hydraulic rod is fixedly connected to the sealing plate. Two guide rods are fixedly installed between the loading and unloading platform and the inner top wall of the housing. Guide holes are provided on the surface of the sealing plate corresponding to the positions of the guide rods.

[0013] Preferably, the pipe cleaning mechanism includes a lever fixedly installed on the upper end of the loading pipe, a rotating rod rotatably connected to the inner top wall of the housing, a threaded groove on the surface of the rotating rod, the lower end of the rotating rod extending to the bottom of the loading and unloading platform, a rotating cylinder rotatably connected to the lower part of the rectangular frame, a first spur gear fixedly installed on the surface of the rotating cylinder, a second spur gear meshing with the first spur gear fixedly connected to the lower end of the rotating rod, a cleaning cylinder threadedly connected to the lower end of the rotating cylinder, and arc-shaped scrapers fixedly connected to the inner walls of both ends of the cleaning cylinder by bolts, with a sludge-absorbing sponge cylinder disposed between the two arc-shaped scrapers.

[0014] Preferably, the lower end of the cleaning cylinder is threaded with a sealing ring, and the lower end of the sealing ring is rotatably connected to a sealing plate via a torsion spring.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention provides a pipe cleaning mechanism inside the box. During loading, the second hydraulic cylinder moves the sealing plate downward, which in turn moves the loading pipe downward, connecting the feed port above the loading pipe with the composite hose inside the tee. During this process, the lever at the top of the loading pipe moves downward along with the loading pipe, causing the rotating rod to rotate. This, in turn, drives the rotating cylinder to rotate through the second spur gear. The arc-shaped scraper inside the rotating cylinder cleans the lower end of the loading pipe. After loading is completed, the loading pipe can also be cleaned when it rises, preventing oil stains from adhering to the loading pipe.

[0019] 2. This invention provides a suction sponge tube between two arc-shaped scrapers inside the rotating cylinder, which can temporarily store the cleaned oil stains and replace them after loading. By threading a sealing ring to the lower end of the rotating cylinder and installing a sealing plate at the lower end of the sealing ring via a torsion spring, the outlet of the loading pipe can be sealed when not loading, preventing foreign objects from entering the loading pipe.

[0020] 3. This invention uses two first hydraulic cylinders to automatically adjust the position of the loading and unloading mechanism, thereby aligning the loading pipe with the oil inlet of the transport vehicle. The entire process is automatically controlled and easy to operate. It adopts a three-way structure to connect the loading pipe and the composite hose, and the structure is simple and compact.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 7 The present invention provides a technical solution: an automatic loading arm for automobiles, including a loading and unloading bracket 1 and an equipment bracket 2. The inner wall of the loading and unloading bracket 1 is provided with a loading and unloading component 3, and the equipment bracket 2 is fixedly installed with an equipment component 4.

[0032] The loading and unloading bracket 1 is set above the loading and unloading vehicle. The loading and unloading bracket 1 includes a support frame 101. Support columns 102 are set at the four corners below the support frame 101. The support columns 102 are fixed to the support frame 101 by U-bolts. The loading and unloading bracket 1 supports the loading and unloading assembly 3.

[0033] The equipment bracket 2 is installed on the side of the loading and unloading bracket 1, and the equipment bracket 2 is used to support the equipment component 4;

[0034] The loading and unloading assembly 3 includes a hydraulic adjustment mechanism 5, a pipeline cleaning mechanism 6, and a loading and unloading mechanism 7. The hydraulic adjustment mechanism 5 adjusts the position of the loading and unloading mechanism 7, and the pipeline cleaning mechanism 6 cleans the pipeline of the loading and unloading mechanism 7.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the hydraulic adjustment mechanism 5 includes a first hydraulic cylinder 501, a rectangular frame 502, and a loading and unloading platform 503. The inner walls of the rectangular frame 502 and the support frame 101 are provided with sliding grooves 504. The rectangular frame 502 and the loading and unloading platform 503 are provided with pulleys 505 on both sides. The loading and unloading platform 503 is located inside the rectangular frame 502. The pulleys 505 are rolledly connected to the sliding grooves 504. There are two first hydraulic cylinders 501. The cylinder bodies of the two first hydraulic cylinders 501 are fixedly connected to the support frame 101, and the two first hydraulic cylinders 501 are set at 90° to each other. The hydraulic rod ends of the two first hydraulic cylinders 501 are fixedly connected to the side of the rectangular frame 502 and the upper surface of the loading and unloading platform 503, respectively.

[0036] Specifically, by extending and retracting the two first hydraulic cylinders 501, the support frame 101 and the rectangular frame 502 are moved left and right and back and forth respectively, thereby adjusting the position of the loading and unloading mechanism 7. The whole process is automatically controlled and easy to operate.

[0037] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, the loading and unloading mechanism 7 includes a housing 701, a composite hose 702, a tee pipe 703, a second hydraulic cylinder 704, and a loading pipe 705. The loading pipe 705 is made of stainless steel and has a diameter of DN200. A sealing plate 706 is welded to the upper end of the loading pipe 705. The tee pipe 703 is sleeved on the surface of the loading pipe 705, and the other end of the tee pipe 703 is connected to the composite hose 702. A feed inlet 707 is provided at the upper end of the loading pipe 705 corresponding to the position where the tee pipe 703 is connected to the composite hose 702. The cylinder body of the second hydraulic cylinder 704 is fixedly installed on the loading and unloading platform 503, and the end of its hydraulic rod is fixedly connected to the sealing plate 706. Two guide rods 708 are fixedly installed between the loading and unloading platform 503 and the inner top wall of the housing 701. A guide hole is provided on the surface of the sealing plate 706 corresponding to the position of the guide rod 708.

[0038] Furthermore, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the pipe cleaning mechanism 6 includes a lever 601 fixedly installed on the upper end of the loading pipe 705. A rotating rod 602 is rotatably connected to the inner top wall of the housing 701. A threaded groove 603 is formed on the surface of the rotating rod 602. The lower end of the rotating rod 602 extends to the bottom of the loading and unloading platform 503. A rotating cylinder 604 is rotatably connected to the bottom of the rectangular frame 502. A first spur gear 605 is fixedly installed on the surface of the rotating cylinder 604. A second spur gear 606 meshing with the first spur gear 605 is fixedly connected to the lower end of the rotating rod 602. When the loading pipe 705 is raised or lowered, the lever 601 moves along the threaded groove 603, causing the rotating rod 602 to rotate. This, in turn, uses the second spur gear 606 at the lower end of the rotating rod 602 to drive the first spur gear 605 on the surface of the rotating cylinder 604 to rotate, thereby causing the rotating cylinder 604 to rotate. The lower end of 604 is threadedly connected to a cleaning cylinder 607. The inner walls of both ends of the cleaning cylinder 607 are fixedly connected to arc-shaped scrapers 608 by bolts. A suction sponge cylinder 609 is set between the two arc-shaped scrapers 608. By setting the suction sponge cylinder 609 between the two arc-shaped scrapers 608 in the rotating cylinder 604, the cleaned oil can be transported to the suction sponge cylinder 609 for temporary storage. It can be replaced after loading. The lower end of the cleaning cylinder 607 is threadedly connected to a sealing ring 610. The lower end of the sealing ring 610 is rotatably connected to a sealing plate 611 by a torsion spring. By threading the sealing ring 610 at the lower end of the rotating cylinder 604 and setting the sealing plate 611 at the lower end of the sealing ring 610 by a torsion spring, the outlet of the loading pipe 705 can be sealed when not loading, so as to prevent foreign objects from entering the loading pipe 705.

[0039] Specifically, by setting a pipe cleaning mechanism 6 inside the housing 701, during loading, the second hydraulic cylinder 704 drives the sealing plate 706 to move downward, which in turn moves the loading pipe 705 downward, so that the feed port 707 above the loading pipe 705 is connected to the composite hose 702 in the tee pipe 703. During this process, the lever 601 at the upper end of the loading pipe 705 moves downward along with the loading pipe 705, causing the rotating rod 602 to rotate, which in turn drives the rotating cylinder 604 to rotate through the second spur gear 606. The arc-shaped scraper 608 inside the rotating cylinder 604 cleans the lower end of the loading pipe 705. After loading is completed, when the loading pipe 705 rises, it can also be cleaned to prevent oil stains from sticking to the loading pipe 705.

[0040] Furthermore, such as Figure 1 As shown, the equipment component 4 includes a feed pipe 401, an electric ball valve 402, an electromagnetic flow meter 403, a manual gate valve 404, and an electrical control box 405. The feed pipe 401 is fixedly installed on the upper end of the equipment support 2. One end of the feed pipe 401 is connected to the composite hose 702 through a flange. The electric ball valve 402, the electromagnetic flow meter 403, and the manual gate valve 404 are installed on the feed pipe 401 in sequence. The electrical control box 405 is installed on the side of the equipment support 2.

[0041] Specifically, the opening and closing of the feed pipe 401 is controlled by the electric ball valve 402, and the flow rate is calculated by the electromagnetic flow meter 403. When the electric ball valve 402 fails, the feed pipe 401 can also be closed by the manual gate valve 404, which plays a protective role.

[0042] Working principle and usage process of this invention:

[0043] First, the transport vehicle drives to the bottom of the loading and unloading support 1 and opens the oil inlet;

[0044] Then, the two first hydraulic cylinders 501 are controlled by the remote computer through the electrical control box 405 to make the discharge port of the loading pipe 705 face the oil filling port of the transport vehicle (the electrical control technology is already very mature, so it will not be described in detail here).

[0045] Secondly, the second hydraulic cylinder 704 is retracted by the control box 405, which pulls the sealing plate 706 downward, thereby causing the loading pipe 705 to move down and push open the sealing plate 611. This moves the feed port 707 at the upper end of the loading pipe 705 into the tee pipe 703 and connects it to the composite hose 702. At the same time, the lower end of the loading pipe 705 extends into the oil inlet of the transport vehicle. During this process, the lever 601 at the upper end of the loading pipe 705 moves down and slides in the threaded groove 603. This causes the rotating rod 602 to rotate, and the second spur gear 606 below the rotating rod 602 drives the first spur gear 605 at the upper end of the rotating cylinder 604 to rotate, thereby causing the rotating cylinder 604 to rotate. The arc-shaped scraper 608 in the cleaning cylinder 607 at the lower end of the rotating cylinder 604 scrapes off the oil stains on the surface of the loading pipe 705. The scraped oil stains are collected along the edge of the arc-shaped scraper 608 into the suction sponge cylinder 609, where the suction sponge cylinder 609 absorbs the oil stains.

[0046] Then, the electric ball valve 402 and electromagnetic flow meter 403 are opened through the electrical control box 405 (the manual butterfly valve is normally open), so that the oil is injected into the transport vehicle through the feed pipe 401, the composite hose 702, and finally the loading pipe 705.

[0047] Finally, after the oil loading and unloading is completed, the electric ball valve 402 is closed, and then the second hydraulic cylinder 704 is extended to push the sealing plate 706 upward, causing it to move the loading pipe 705 upward and away from the transport vehicle. When the second hydraulic cylinder 704 extends to its maximum value, the loading pipe 705 retracts into the sealing ring 610, and the sealing plate 611 seals the discharge end of the loading pipe 705. During the process of the loading pipe 705 rising, the arc-shaped scraper 608 scrapes off the oil adhering to the surface of the loading pipe 705 to prevent the oil from adhering to the surface of the loading pipe 705.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
