Description

Technical Field

[0001] The utility model relates to the technical field of lifting platforms, in particular to an adjustable hydraulic lifting platform device. Background Art

[0002] A lifting platform is a multifunctional lifting and loading and unloading mechanical equipment, which can be divided into fixed and mobile, guide rail and articulated arm types. Fixed types include scissor-type lifting freight elevators, chain lifts, loading and unloading platforms and attached electric construction platforms. Mobile types include four-wheel mobile lifting platforms, two-wheel traction lifting platforms, car-modified lifting platforms, hand-push lifting platforms, hand-cranked lifting platforms, AC / DC dual-purpose lifting platforms, battery-mounted lifting platforms, self-propelled lifting platforms, diesel engine articulated arm self-propelled lifting platforms, folding arm lifting platforms, cylinder lifting platforms and aluminum alloy lifting platforms.

[0003] The Chinese authorized announcement number CN216737450U is a guide rail type hydraulic lifting platform. The guide rail type hydraulic lifting platform uses an adjustable railing device to enable the objects to be directly pushed through the triangular plate by rotating the angle of the adjustment plate when transporting large objects, so that the objects pass through the triangular plate and then reach the interior of the lifting platform device through the adjustment plate, which is more convenient for the staff to use. By setting a fixing device, the adjustment plate is fixed after the pin passes through the fixing plate. When the pin is inserted into the slot, it is inserted through the grooves opened on both sides of the slot. After insertion, the pin is rotated to make the protrusion rotate and engage with the annular groove opened at the bottom of the slot, so that the pin will not move when subjected to external force, preventing the staff or objects from colliding with the pin during work, causing the pin to move and the fixing effect to fail.

[0004] There are still certain deficiencies in use. When the lifting platform is in use, the top of the platform cannot be adjusted accordingly according to the actual height of the cargo being carried. The cargo may accidentally slip from the top of the platform, thereby reducing the safety of the lifting platform during use. At the same time, when the platform is in a high position, it is only supported by the cylinder, and the platform may accidentally fall, which will also reduce the safety of the platform during use.
