[0005] Preferably, the sliding mechanism includes: a hydraulic fixed top, which is fixedly installed on the outer surface of one end of the chassis frame close to the roller, and the hydraulic fixed top is evenly distributed on the outer surface of the chassis frame. A sliding top rod is slidably installed on the outer surface of the sliding guide rod, and the sliding top rod and the sliding guide rod are connected by bolts. A support frame is fixedly installed on the outer surface of the sliding top rod, and the outer surface of the support frame is covered with a rubber pad, and the support frame is L-shaped.

[0006] By adopting the above technical solution, the freight elevator is placed under the window that needs to be transported, and the support frame is inserted into the upper edge of the window. Then, the position of the sliding top rod on the sliding guide rod is adjusted to leave a gap between the sliding top rod and the window. Then, the roller is separated from the ground by starting the hydraulic fixed top, so that the chassis frame rises and the support frame is fitted with the window, so that the freight elevator can be quickly erected and fixed. The L-shaped design of the support frame is engaged with the window to reduce the probability of the chassis frame shifting when the conveyor box moves, so that the freight elevator can be easily and quickly erected, and at the same time, it can be moved and erected elsewhere for use.

[0007] Preferably, an engaging and pulling mechanism is provided between the chassis frame and the sliding top rod, and the conveying box is driven to move on the sliding guide rod by the engaging and pulling mechanism.

[0008] By adopting the above technical solution, the operation of the driving motor can drive the turbine reel to rotate, and the turbine reel can tighten or loosen the cable, thereby driving the conveying box to move up and down on the sliding guide rod.

[0010] By adopting the above technical solution, the rotation of the driving motor can drive the worm to rotate, so that the turbine reel that meshes with the worm can follow the rotation movement. Through the self-locking property of the turbine reel and the worm, the turbine reel will not slip when reeling or unreeling the cable. At the same time, in the event of a sudden power outage, the conveyor box will not fall and cause a safety accident.

[0011] Preferably, a pulling and traction frame is slidably installed inside the chassis frame, and the outer surface of one end of the pulling and traction frame is engaged with the chassis frame. The chassis frame and the pulling and traction frame are rotatably connected, and an annular pulling piece is provided on the outer surface of the pulling and traction frame.

It can be suitable for automatic unloading and manual unloading.

[0015] Preferably, a pushing cylinder is fixedly mounted on the outer surface of the conveying box, and the pushing cylinder is located between the conveying box and the conveyor belt. An extension plate is slidably mounted on the outer surface of the conveying box, and the extension plate is connected to the output end of the pushing cylinder. The extension plate is inclined in design, and the extension plate is engaged with the conveying box.

[0016] By adopting the above technical solution, when the conveying box contacts the trigger switch, the push cylinder will push out the extension plate, so that the extension plate extends into the interior of the window and crosses the thickness of the window opening, and the object frame pushed out by the conveyor belt will slide out along the inclined surface of the extension plate, so that the object frame will not fall on the window edge and cause it to overturn and fall.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the portable multifunctional freight elevator:

[0018] 1. After moving the freight elevator to the place where it needs to be installed, insert the support frame into the upper end of the window sill, and adjust the height of the sliding top rod to keep a certain distance between the support frame and the window sill. Then, start the hydraulic fixed top to prop up the chassis frame, so that the support frame is stuck into the window sill. The L-shaped design of the support frame prevents the elevator from being offset when in use. By adjusting the length of the sliding guide rod and the sliding top rod, and coordinating with the lifting of the hydraulic fixed top, the freight elevator can be fixed in different places. At the same time, it can be transported by rollers, so that the disassembled freight elevator can be moved to other places for rapid erection;

[0019] 2. Put the item frame into the conveyor box, then start the drive motor to drive the worm to rotate, so that the turbine reel engaged with the worm rotates. Through the self-locking property of the worm and the turbine reel, when the turbine reel is reeling in or unreeling the cable, the conveyor box will not automatically slide down on the sliding guide rod to cause a safety accident;

[0020] 3. When the conveyor box rises to the limited position, it will contact the trigger switch, triggering the conveyor belt to rotate, and start the push cylinder to push the extension plate outward. When the conveying device is docked with the freight elevator, the flexible interception lever can be opened to allow the conveyor belt to rotate and push the item frame out, allowing the item frame to slide outward along the inclined surface of the extension plate and fall onto the conveying device for automatic unloading. When there is no conveying device for docking, the flexible interception lever can be pulled down so that the flexible interception lever can intercept the item frame, so that the flexible interception lever can block the item frame, so that the item column can cross the window edge to reduce the probability of the item frame tipping over, and manual unloading and automatic unloading can be performed at the same time.
