Description

Technical Field

[0001] This utility model relates to the technical field of oil mobile lifting platforms, and in particular to a mobile lifting platform. Background Technology

[0002] Oil refers to liquid substances used for lubrication, fuel, or other purposes. A lifting platform is a mechanical device used for vertical transportation of personnel or goods. It operates through hydraulic, electric, or mechanical transmission systems. A mobile lifting platform is a type of lifting equipment with mobility capabilities. It not only possesses the basic functions of a regular lifting platform but also features devices for easy movement. Oil is typically stored in large tanks or drums, and loading and unloading require lifting these drums or tanks to a certain height for transportation or storage; hence, a mobile lifting platform is used.

[0003] A search revealed Chinese Patent Publication No. CN211862087U, which discloses a mobile lifting platform, including a base. The base is connected to four support rods, each support rod being connected to a caster wheel, and each caster wheel having a stop switch. The base is connected to a fixed seat, and the fixed seat is fixedly connected to a fixed rod. The fixed rod is slidably connected to a sliding tube, and the sliding tube is fixedly connected to a tabletop. A gas spring is disposed between the support rods and the sliding tube. The gas spring includes a fixed part, a moving part, and a push-button switch. The fixed part is fixedly connected to the support rods, the moving part is fixedly connected to the sliding tube, and the push-button switch is connected to an adjustment device.

[0004] In the aforementioned utility model, a gas spring and a corresponding adjustment device are provided. This adjustment device, by operating the pressing plate, pulls the connecting rope, which in turn pulls the connecting lever. Due to the lever principle, the pressing part presses the switch, thus allowing for timely adjustment of the table height. Since the lifting platform has only one lifting leg, there is no need to consider the issue of synchronous lifting, allowing the lifting platform to complete lifting quickly. Simultaneously, the presence of casters allows for convenient movement of the lifting platform, and the casters are further secured by stop switches. Therefore, the lifting platform has good mobility. However, in actual use, when the lifting platform needs to be secured after movement, the securing effect may still be poor, and the platform may easily shift again. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mobile lifting platform, which aims to improve the problem of poor fixation of the lifting platform after it has been moved, which easily leads to movement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mobile lifting platform, comprising a chassis, a connecting piece fixedly connected to the outer wall of the chassis, a connecting shaft rotatably connected to the inside of the connecting piece, a first cylinder fixedly connected to the outer wall of the connecting shaft, a first rotating shaft fixedly connected to the output end of the first cylinder, a rotating plate fixedly connected to the outer wall of the first rotating shaft, a second rotating shaft fixedly connected to the inside of the rotating plate, a fixing block rotatably connected to the outer wall of the second rotating shaft, the outer wall of the fixing block fixedly connected to the outer wall of the chassis, a vertical plate rotatably connected to the outer wall of the first rotating shaft, a fixing seat fixedly connected to the lower surface of the vertical plate, wheels provided inside the chassis, and a lifting assembly provided inside the chassis.

[0007] The above technical solution works as follows: starting the first cylinder allows the rotating plate to rotate via the sliding of the first rotating shaft. The rotation of multiple rotating plates can cause multiple upright plates and fixed seats to detach from the ground, thereby allowing the wheels to contact the ground. When the wheels are in contact with the ground, the platform can be moved. Conversely, when the fixed seats are in contact with the ground, the platform can be fixed and provided with stable support.

[0008] As a further description of the above technical solution:

[0009] The lifting assembly includes a second cylinder, the outer wall of which is fixedly connected to the inside of the chassis, a support base is fixedly connected to the output end of the second cylinder, a first support plate is fixedly connected to the lower surface of the support base, a second support plate is slidably connected to the outer wall of the first support plate, and the lower surface of the second support plate is fixedly connected to the upper surface of the chassis.

[0010] The above technical solution allows for flexible adjustment of the height of the support base via the second cylinder, thereby adjusting the height of the platform. Simultaneously, the first support plate slides along with the support base, providing auxiliary support.

[0011] As a further description of the above technical solution:

[0012] The support base is slidably connected to a guardrail, and the outer wall of the guardrail is fixedly connected to a limit strip. The outer wall of the limit strip is slidably connected to the inside of the support base.

[0013] With the above technical solution, when the limiting strip is stuck inside the support base, the position of the guardrail can be restricted, and it will not fall off the support base due to external force. Oil can be placed through the guardrail.

[0014] As a further description of the above technical solution:

[0015] The support base is slidably connected to a protective plate, and the outer wall of the protective plate is slidably connected to the outer wall of the guardrail.

[0016] The above technical solution aims to fix the position between the protective plate and the support base, thereby blocking the guardrail and making its position inside the support base more stable.

[0017] As a further description of the above technical solution:

[0018] The support base is fixedly connected to a fixed column, and the fixed column is slidably connected to a sliding column.

[0019] Through the above technical solution, the fixed column supports the sliding column, and the support base supports the fixed column, which allows the sliding column to slide stably inside the fixed column.

[0020] As a further description of the above technical solution:

[0021] A pull tab is fixedly connected to the outer wall of the sliding column, and a fixing plate is also fixedly connected to the outer wall of the sliding column.

[0022] Through the above technical solution: the sliding column has a fixing effect on the pull plate. By pulling the pull plate, the sliding column can slide synchronously, and thus the fixing plate slides synchronously with the sliding column.

[0023] As a further description of the above technical solution:

[0024] The outer wall of the fixing plate is slidably connected to the inside of the fixing column, and a spring is fixedly connected to the outer wall of the fixing plate. The outer wall of the spring is fixedly connected to the inside of the fixing column.

[0025] With the above technical solution: the fixed plate will slide stably inside the fixed column due to the sliding of the sliding column, and the spring is set between the fixed plate and the fixed column, so that it can be squeezed due to the sliding of the fixed plate.

[0026] As a further description of the above technical solution:

[0027] The outer wall of the fixing plate is fixedly connected to a locking post, the outer wall of the locking post is slidably connected to the inside of the fixing post, and the outer wall of the locking post is slidably connected to the inside of the protective plate.

[0028] Through the above technical solution: the fixing plate has the function of fixing the locking post, and the locking post will slide synchronously with the sliding of the fixing plate. When the locking post is retracted into the protective plate, the protective plate can be installed. When the locking post slides into the protective plate, the protective plate and the support base can be fixed.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the first cylinder is activated, and through the cooperation between the first rotating shaft, rotating plate, second rotating shaft, fixed block, upright plate and fixed seat, the position of the wheel is adjusted by adjusting the position of the fixed seat, so as to quickly move the guardrail to the designated position and fix it after moving, which is suitable for flexible switching in multiple sites.

[0031] 2. In this utility model, pulling the pull tab allows the guardrail to slide into the support base through the cooperation of the fixed column, sliding column, fixed plate, spring, and locking column. The locking column can limit and fix the protective plate and the support base, achieving the effect of quick assembly and installation of the platform, which is convenient for use or maintenance.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a mobile lifting platform, including a chassis 1, a connecting piece 2 fixedly connected to the outer wall of the chassis 1, a connecting shaft 3 rotatably connected inside the connecting piece 2, a first cylinder 4 fixedly connected to the outer wall of the connecting shaft 3, a first rotating shaft 5 fixedly connected to the output end of the first cylinder 4, a rotating plate 6 fixedly connected to the outer wall of the first rotating shaft 5, a second rotating shaft 7 fixedly connected inside the rotating plate 6, a fixing block 8 rotatably connected to the outer wall of the second rotating shaft 7, the outer wall of the fixing block 8 fixedly connected to the outer wall of the chassis 1, a vertical plate 9 rotatably connected to the outer wall of the first rotating shaft 5, a fixing seat 10 fixedly connected to the lower surface of the vertical plate 9, wheels 11 provided inside the chassis 1, and a lifting assembly 12 provided inside the chassis 1.

[0041] Specifically, the connecting piece 2 is fixed to the outer wall of the chassis 1 and supports the connecting shaft 3. The connecting shaft 3 connects the connecting piece 2 and the first cylinder 4. During the operation of the first cylinder 4, the connecting shaft 3 will rotate inside the connecting piece 2. The first rotating shaft 5 can slide through the driving action of the first cylinder 4. The rotating plate 6 fixes the first rotating shaft 5 and can rotate through the sliding action of the first rotating shaft 5. The second rotating shaft 7 rotates inside the fixed block 8 and provides stable support for the rotation of the rotating plate 6. The upright plate 9 supports the first rotating shaft 5. The first rotating shaft 5 is evenly arranged on the upper and lower parts of the upright plate 9, and the first cylinder 4 is only connected to the upper first rotating shaft 5. The position of the upright plate 9 can be adjusted by the joint rotation of the two rotating plates 6. The upright plate 9 fixes the fixed seat 10 and can drive the fixed seat 10 to detach from the ground. At this time, due to the rise of the upright plate 9 and the fixed seat 10, the wheels 11 can contact the ground, and the position of the lifting platform can be moved. When the fixed seat 10 contacts the ground, it can provide stable support for the platform.

[0042] Reference Figure 1 The lifting assembly 12 includes a second cylinder 1201. The outer wall of the second cylinder 1201 is fixedly connected to the inside of the chassis 1. The output end of the second cylinder 1201 is fixedly connected to a support base 1202. The lower surface of the support base 1202 is fixedly connected to a first support plate 1203. The outer wall of the first support plate 1203 is slidably connected to a second support plate 1204. The lower surface of the second support plate 1204 is fixedly connected to the upper surface of the chassis 1.

[0043] Specifically, the chassis 1 fixes the second cylinder 1201. The second cylinder 1201 drives the support seat 1202 to slide. The support seat 1202 fixes the first support plate 1203. The second support plate 1204 is fixed on the upper surface of the chassis 1 and supports the sliding of the first support plate 1203, providing stable auxiliary support for the sliding of the support seat 1202.

[0044] Reference Figure 3 , Figure 4 and Figure 5 The support base 1202 has a sliding connection to a guardrail 13 inside, and a limit strip 14 is fixedly connected to the outer wall of the guardrail 13. The outer wall of the limit strip 14 is slidably connected to the inside of the support base 1202. The support base 1202 has a sliding connection to a protective plate 15 inside, and the outer wall of the protective plate 15 is slidably connected to the outer wall of the guardrail 13. The support base 1202 has a fixed connection to a fixed post 16 inside, and a sliding post 17 is slidably connected to the inside of the fixed post 16. The outer wall of the sliding post 17 has a fixed connection to a pull tab 18, and a fixed plate 19. The outer wall of the fixed plate 19 is slidably connected to the inside of the fixed post 16. The outer wall of the fixed plate 19 has a fixed connection to a spring 20, and the outer wall of the spring 20 is fixedly connected to the inside of the fixed post 16. The outer wall of the fixed plate 19 has a fixed connection to a locking post 21, and the outer wall of the locking post 21 is slidably connected to the inside of the fixed post 16. The outer wall of the locking post 21 is also slidably connected to the inside of the protective plate 15.

[0045] Specifically, the support base 1202 supports the guardrail 13, and the guardrail 13 fixes the limiting strip 14. When the guardrail 13 and the limiting strip 14 are slid into the support base 1202 simultaneously, the limiting strip 14 restricts the position of the guardrail 13 inside the support base 1202. The protective plate 15 limits the guardrail 13. When the protective plate 15 is installed on the outside of the guardrail 13, it can block the guardrail 13. The fixing post 16 is fixed inside the support base 1202 and supports the sliding post 17. The sliding post 17 fixes the pull tab 18. The 7 fixing plates 19 serve to fix the platform. By pulling the pull tab 18, the fixing plates 19 can slide inside the fixing column 16. The spring 20 will also be compressed due to the sliding of the fixing plates 19. The fixing plates 19 fix the locking column 21, allowing the locking column 21 to slide into the interior of the fixing column 16 simultaneously. Align the protective plate 15 with the support base 1202, release the pull tab 18, and the spring 20 will rebound after compression. By pushing the locking column 21 in the opposite direction, the protective plate 15 can be fixed to the support base 1202 through the locking column 21, thus completing the rapid installation of the lifting platform.

[0046] Working principle: When the lifting platform is needed, the support base 1202 and guardrail 13 are quickly installed and used. The guardrail 13 and the limiting strip 14 are slid into the support base 1202. Pull the pull tab 18, which will drive the sliding column 17 and the fixing plate 19 to slide simultaneously. During the sliding process, the spring 20 is squeezed. When the fixing plate 19 slides, it will retract the locking column 21 into the fixing column 16. At this time, the protective plate 15 can be placed in the support base 1202. Release the pull tab 18. The spring 20 will push the locking column 21 in the opposite direction to lock it into the protective plate 15. By fixing the protective plate 15, the position of the guardrail 13 can be limited, achieving the effect of quick assembly and installation of the platform, which is convenient for use or maintenance.

[0047] Activating the second cylinder 1201 can push the support base 1202 to rise or fall, flexibly adjusting the height of the guardrail 13. The first support plate 1203 provides auxiliary support, facilitating the raising of the oil to a suitable height. When the platform needs to be moved, activating the first cylinder 4 will push the first rotating shaft 5 to slide. When the first rotating shaft 5 slides, it will cause the rotating plate 6 on the outer wall to rotate. The rotating plate 6 will then cause the second rotating shaft 7 to rotate via the fixing block 8. Simultaneously, the first cylinder 4 will also cause the connecting shaft 3 to rotate. Similarly, when the first rotating shaft 5 slides... The platform 9 and the fixed base 10 slide together, and the fixed base 10 is lifted off the ground by the rotation of the rotating plate 6. At this time, the wheels 11 can be brought into contact with the ground by the chassis 1. The wheels 11 can move the platform, so as to quickly move the guardrail 13 to the designated position and provide stable support for the platform after the movement. This platform is suitable for flexible switching between multiple sites. The lifting platform can not only achieve the effect of quick assembly and installation of the platform, which is convenient for use or maintenance, but also achieve the effect of quickly moving the guardrail 13 to the designated position and providing stable support for the platform after the movement. This platform is suitable for flexible switching between multiple sites.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
