Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery technology, specifically a mobile lifting platform with a detachable hydraulic arm. Background Technology
[0002] Mobile lifting platforms, as important material handling equipment, are widely used in factory maintenance, warehousing and logistics, and construction. Traditional lifting platforms generally use a fixed hydraulic arm structure, which is inconvenient for assembling and disassembling the hydraulic arm. Most equipment uses bolted connections, requiring special tools for each disassembly and assembly, taking 15-30 minutes each time, seriously affecting work efficiency. Existing quick-release structures mostly use a purely mechanical pin design, which is prone to developing clearances after long-term use, causing the hydraulic arm to wobble and posing safety hazards. Traditional bolted connections are time-consuming to assemble and disassemble, while existing quick-release structures have defects such as large clearances and easy loosening. At the same time, ordinary mobile casters have poor stability when working on inclined ground and lack effective automatic leveling and safety warning systems, making it difficult to meet the safety requirements of high-altitude operations. To address these problems, although the industry has tried to use electromagnetic locking and hydraulic leveling as improvement solutions, they generally have new problems such as complex structure, high cost, or insufficient reliability. Especially under frequent disassembly and assembly conditions, existing technologies struggle to simultaneously meet the two core requirements of ease of operation and connection reliability. Utility Model Content
[0003] To solve the above problems, this utility model provides the following technical solution: a mobile lifting platform with a detachable hydraulic arm, including a lifting platform base, a detachable hydraulic arm assembly, a hydraulic drive mechanism, and movable casters. The detachable hydraulic arm assembly is detachably connected to the lifting platform base through a quick-connect mechanism. The quick-connect mechanism includes a tapered insertion structure disposed at the root of the hydraulic arm, an electromagnetic locking ring disposed at the docking end of the base, and a mechanical safety pin penetrating the tapered insertion portion with a taper of 1:5 to 1:8. The mechanical safety pin is provided with a visual locking indicator.
[0004] Preferably, the movable casters are hinged to the lower end of the lifting platform base via four sets of independent hydraulic leveling outriggers, and the lower part of the movable casters is provided with liftable rubber anti-slip blocks with a descent stroke ≥30mm.
[0005] Preferably, the hydraulic leveling outrigger is equipped with a tilt compensation component, which automatically starts the leveling program when the platform tilt exceeds 3°.
[0006] Preferably, the quick-connect mechanism integrates a contact pressure sensor, which triggers an audible and visual alarm when the detected pressure value is lower than a set threshold.
[0007] Preferably, the disassembly and assembly interface of the hydraulic arm assembly is provided with a dustproof sealing cover, which is made of magnetic rubber material.
[0008] Preferably, the bottom surface of the rubber anti-slip block is provided with radial drainage grooves, the groove depth is 2-3mm, and the groove spacing is 10±1mm.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: through the coordinated cooperation of the conical plug-in structure and the electromagnetic locking ring, the operation time is shortened to less than 1 minute, realizing the rapid disassembly and assembly and reliable locking of the hydraulic arm; the four sets of independent hydraulic leveling outriggers, together with the liftable anti-slip block, improve the stability of the equipment when working on inclined ground; the integrated pressure sensing and audible and visual alarm system can monitor the connection status in real time, effectively preventing safety accidents; the overall structure improves work efficiency while ensuring safety, and is particularly suitable for industrial scenarios that require frequent movement.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0013] like Figure 1As shown, the movable lifting platform of the detachable hydraulic arm in this embodiment includes a lifting platform base 1, a detachable hydraulic arm assembly 2, a hydraulic drive mechanism 3, and movable casters 4. The detachable hydraulic arm assembly 2 is detachably connected to the lifting platform base 1 through a quick connection mechanism 5. The quick connection mechanism 5 includes a tapered insertion structure 501 disposed at the root of the hydraulic arm, an electromagnetic locking ring 502 disposed at the docking end of the base, and a mechanical safety pin 503 penetrating the tapered insertion part with a taper of 1:5 to 1:8. The mechanical safety pin 503 is provided with a visual locking indicator.
[0014] The movable caster 4 is hinged to the lower end of the lifting platform base 1 by four sets of independent hydraulic leveling legs 6. The lower part of the movable caster 4 is equipped with a liftable rubber anti-slip block 7 with a descent stroke ≥30mm.
[0015] The hydraulic leveling outrigger 6 is equipped with a tilt compensation component 8, which automatically starts the leveling program when the platform tilt exceeds 3°.
[0016] The quick-connect mechanism 5 integrates a contact pressure sensor 504, which triggers an audible and visual alarm 505 when the detected pressure value is lower than a set threshold.
[0017] The hydraulic arm assembly 2 is equipped with a dustproof sealing cover 9 at the disassembly and assembly interface. The sealing cover 9 is made of magnetic rubber material.
[0018] The bottom surface of the rubber anti-slip block 7 is provided with radial drainage grooves 701, with a groove depth of 2-3mm and a groove spacing of 10±1mm.
[0019] The working principle of this utility model is as follows: The conical plug-in structure 501 is aligned with the base interface and inserted. The electromagnetic locking ring 502 is energized to generate a radial locking force of 8-12kN to achieve initial fixation. Then, the mechanical safety pin 503 is inserted to complete the double locking. During operation, the tilt compensation component 8 monitors the platform posture in real time. When the tilt exceeds 3°, the height of the hydraulic leveling outrigger 6 is automatically adjusted. At the same time, the rubber anti-slip block 7 is pressed down by 30mm to enhance stability. The pressure sensor 504 continuously monitors the connection status and triggers an alarm when there is an abnormality. When disassembling, the detachable hydraulic arm assembly 2 can be quickly separated by reversing the operation. The entire system achieves a balance between safety and ease of operation through electromechanical-hydraulic coordinated control.
