Technical Field

The invention relates to the technical field of vehicle-mounted square cabins, in particular to a vehicle-mounted shelf arranged in a square cabin.

Background

For the vehicle-mounted shelter, a shelf is usually required to be installed in the cabin for placing some important equipment or boxes, and when the volume and weight of some equipment or boxes are large and heavy, the cabin can be accessed by a hoisting mode. For example, the two sides of the carriage of the medical shelter are provided with shelves for placing medical first-aid kits, which are generally heavier, and when the carriage door is opened, the medical first-aid kits are placed on or taken out of the shelves, which can be completed quickly by means of the hoisting device. However, the existing shelter and shelf have no lifting function, and special lifting equipment must be additionally searched for matching, so that the operation is inconvenient.

Disclosure of Invention

The invention aims to provide a vehicle-mounted shelf with a lifting function, which can conveniently and quickly put a box body into the shelf or take the box body out of the shelf.

In order to solve the technical problems, the technical scheme of the invention is as follows: a vehicle-mounted goods shelf with a lifting function comprises a fixed frame, a slide rail, a movable frame, a movable bottom plate and a lifting mechanism, wherein the fixed frame is arranged in a carriage of an automobile; one end of the sliding rail is arranged at the upper part of the fixed frame through a screw, the other end of the sliding rail is arranged on the movable frame through a screw, and the movable frame can horizontally push and pull relative to the fixed frame through the sliding rail; the lifting mechanism comprises a servo motor, a speed reducer and a rotating shaft which are installed on the movable frame, the speed reducer is installed in the middle of the movable frame, the speed reducer is provided with two output ends which are bilaterally symmetrical, the two output ends are respectively connected with one rotating shaft through a coupler, the installation direction of the rotating shaft is perpendicular to the installation direction of the sliding rail, the outer side ends of the two rotating shafts are respectively provided with a hoisting wheel, the two hoisting wheels are respectively provided with a steel wire rope, and the lower ends of the steel wire ropes are connected with the two ends of the movable bottom plate; the movable bottom plate can vertically lift relative to the movable frame under the action of the lifting mechanism and the steel wire rope.

The operation method of the technical scheme is as follows: when the goods shelves are placed to the box to needs, at first with movable frame pull play from fixed frame, because movable bottom plate is connected with the pivot of installing on movable frame through wire rope, movable bottom plate will follow movable frame and carry out horizontal migration like this, after movable frame and movable bottom plate are pulled out, down transfer wire rope through hoist mechanism, make movable bottom plate fall to ground, the reuse is artifical to be moved the box to movable bottom plate on, then hoist mechanism upwards receives wire rope, make movable bottom plate and the box on it move to goods shelves relevant position perpendicularly upwards, at last with movable frame together with movable bottom plate and box horizontal propelling movement to on-vehicle goods shelves in. When the box body needs to be taken out of the shelf, the operation process is similar.

Preferably, the hoisting wheel is a single-groove hoisting wheel. The hoisting wheel adopting the single-groove structure can ensure that the steel wire ropes on the left side and the right side can be hoisted synchronously, and the condition that the movable bottom plate is high on one side and low on the other side is avoided.

Further, the lifting mechanism further comprises an input handle.

Further, the speed reducer is a planetary speed reducer and comprises a first speed reducer and a second speed reducer which are connected with each other. The multi-stage speed reducer is matched to realize high-speed-ratio and high-torque output.

Preferably, the slide rail is a three-section slide rail.

the invention has the beneficial effects that: according to the invention, the movable frame is connected with the fixed frame through the slide rail, and the lifting mechanism is integrated on the movable frame, so that the goods can be lifted and transversely moved, the goods can be quickly placed on the goods shelf and quickly taken out of the goods shelf, and the working efficiency is greatly improved.
