[0049] Safety and warning function

[0050] The warning light serves as a visual prompt signal, which can avoid misoperation and personnel entering a dangerous area. The mechanical locking mode of the screw rod and the pressing block can provide additional safety protection in the case of hydraulic failure

[0051] Working principle: The hydraulic elevator of the present application mainly relies on the hydraulic system to drive and cooperate with multiple structures such as damping, guiding, and direction adjusting to realize the stable lifting and flexible conveying of goods.

[0052] Overall bearing and damping effect

[0053] The support base plate 1 serves as a bottom foundation bearing member to ensure the stability of the whole machine. The top of the support base plate is provided with a damping structure composed of a base block 28, a clamping cover block 29, a pressing plate 30, and a spring rod 31.

[0054] During the operation of the elevator, when external environmental vibration or load impact is transmitted to the damping structure through the support base plate, the spring rod will elastically deform to absorb and release the impact, thereby ensuring the stability of the lifting platform during operation and reducing the vibration damage to the materials.

[0055] Direction adjusting and multi-point distribution: The direction adjusting motor 2 is arranged above the damping structure, and the output end of the direction adjusting motor drives the direction adjusting disc 3 to rotate. The outer wall of the direction adjusting disc is provided with an annular groove, and multiple lifting structures are uniformly distributed outside the annular groove.

[0056] When the direction adjusting motor drives the direction adjusting disc to rotate, different lifting structures can be adjusted to the appropriate angle according to the needs, realizing multi-direction and multi-point material conveying and improving the operation flexibility.

[0057] Working process of the lifting structure one

[0058] The lifting structure one is mainly composed of a guide plate 8, an oil cylinder 9, a liquid pump, a guide oil pipe 10, a hydraulic lifting pipe 16, and a top tray 17.

[0059] The oil cylinder pushes the hydraulic oil to flow under the action of the liquid pump, and the oil enters the hydraulic lifting pipe through the guide oil pipe. The hydraulic lifting pipe extends upward under the pressure to drive the top tray to lift.

[0060] The top tray can form an adjustable clamping mechanism through the protrusions 24, the threaded pipes 25, the screw rods 26, and the pressing blocks 27, which can stably support and lock the building materials to prevent sliding during transportation.

[0061] Working process of the lifting structure two

[0062] The second lifting structure is composed of the inclined frame plate 18, the bottom support plate 19, the casting block 20, the second hydraulic cylinder 21 and the placing frame 22.

[0063] When the second hydraulic cylinder is extended or retracted, the placing frame is moved up and down along the sliding groove, and the elastic pad 23 is arranged in the placing frame to provide buffering and protection when heavy objects are transported.

[0064] The placing frame is suitable for carrying regular or irregular objects, and realizes the transportation of large or special-shaped components.

[0065] Safety and prompt

[0066] The warning light 32 is installed on the top of the top frame plate 5, and when the elevator is running or in a load state, the warning light is lit or flashes to remind the construction personnel to keep a safe distance.

[0067] The integrated working principle of overall shock absorption and stability, steering distribution, hydraulic drive, load buffering and safety prompting realizes efficient, safe and flexible lifting of construction goods.
