Detailed Description

The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the utility model and together with the description, serve to explain the principles of the utility model and not to limit the scope of the utility model.

Referring to fig. 1, the lifting device for assembling the construction machine comprises a carrying plate 1, a lifting mechanism 2 and a foot switch 3, wherein the lifting mechanism 2 is in transmission connection with the carrying plate 1 and can drive the carrying plate 1 to move upwards. The foot switch 3 is electrically connected with the lifting mechanism 2, and the foot switch 3 can close the circuit to electrify the lifting mechanism 2 and lift the object carrying plate 1.

In the present embodiment, for convenience of use, a frame 4 is generally further provided, and the frame 4 is placed on the working floor. A sliding groove 41 is arranged on the frame 4 along the vertical direction, and the object carrying plate 1 is in sliding connection with the sliding groove 41 in a matching manner. The loading plate 1 can be driven to move upwards along the sliding groove 41 under the driving action of the lifting mechanism 2.

In the present embodiment, the lifting mechanism 2 includes a motor 21, a fixed pulley 22, and a cable 23. The fixed pulley 22 is fixedly arranged on the frame 4 and is positioned above the sliding chute 41. One end of the cable 23 is fixedly connected with the rotating shaft of the motor 21, and the other end of the cable is fixedly connected with the carrying plate 1 by passing through the fixed pulley 22. When the motor 21 works, the rotating shaft rotates and winds the cable 23, and the cable 23 pulls the loading plate 1 to be lifted. In order to allow the carrier plate 1 to be lifted even better without getting stuck in the chute 41, it is preferable that the part of the cable 23 between the carrier plate 1 and the fixed pulley 22 is parallel to the chute 41.

In the present embodiment, the carrier plate 1 includes a connecting plate 11, a carrying plate 12 and a reinforcing plate 13. The connecting plate 11 is slidably connected with the sliding groove 41, the upper surface of the bearing plate 12 is horizontal and used for bearing a heavy object, and the lower surface of the bearing plate 121 is fixedly connected with the connecting plate 11 through the reinforcing plate 3. The cable 23 is fixedly connected to the connecting plate 11, and pulls the connecting plate 11 to move the bearing plate 12.

The foot switch 3 is generally designed to be closed by foot in order to facilitate the use of the carrier. Therefore, in the present embodiment, the foot switch 3 is disposed at the bottom of the frame 4, and includes a fixed portion 31, a rotating portion 32, and a return spring 33. The fixed portion 31 is fixedly connected with the frame 4, and the rotating portion 32 is disposed above the fixed portion 31 and rotatably connected with the frame 4. The return spring 33 is located between the fixed portion 31 and the rotating portion 32, and has upper and lower ends respectively connecting the rotating portion 32 and the fixed portion 31. The rotating portion 32 can rotate when receiving an external force (e.g., stepping), and contacts the fixing portion 31 to conduct a circuit.

The fixed part 31 and the rotating part 32 are communicated with the motor 21 through necessary leads, and it is easy to know that the contact part of the fixed part 31 and the rotating part 32 is conductive, and other parts are wrapped by insulating protective skins to avoid electric leakage.

When the device is used, the motor 21 is powered on, and then heavy objects, usually bagged materials, are moved from the ground to the bearing plate 12. The carrier then stands facing or facing away from the carrier plate 12 and closes it by stepping on the foot switch 3. The loading plate 12 is slowly lifted up with the weight under the action of the motor 21. When the lifting platform rises to the position near the shoulder height of a worker, the worker can turn over the heavy object by hands to turn over the shoulder of the carrier, and the worker can carry the heavy object to walk away. After the porter walks, the foot switch 3 is automatically switched off, the motor 21 is powered off and stops working, and the object carrying plate 1 falls back to the ground under the action of gravity. Therefore, a shock absorbing cushion can be preferably arranged right below the carrier plate 1, so that the carrier plate 1 is prevented from being broken or generating great noise when falling down.

And since the carrier plate 1 needs to be lifted to the height of the shoulders of the worker, the height of the top end of the chute 41 is accordingly at least 2 meters, thereby ensuring satisfaction of the requirements.

The embodiment of the utility model has the following beneficial effects: the lifting device for assembling the construction machinery has simple structure and low cost, and is convenient to be widely applied; when the carrying plate is used, a carrier only needs to move the heavy object to the carrying plate firstly, then stands and treads the foot switch to enable the lifting mechanism to be electrified and lift the carrying plate, when the carrying plate is lifted to the shoulder height, the heavy object is moved to the shoulder of the carrier, the carrier does not need to carry the heavy object by the carrier, and the occupational injury of the carrier is greatly reduced.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
