Abstract
A folding type working platform comprises a middle frame and side frames at two sides of the folding type working platform, wherein the two side frames are respectively connected with two sides of the middle frame in pivot mode through one rotating shaft, the middle frame is used to be directly connected with a lifter, a four-bar mechanism is arranged between the middle frame and one side frame, and a driving machine is arranged between the middle frame and the other side frame. The four-bar mechanism and the driving machine can drive the side frames to carry out the actions of rotating and folding relative to the middle frame, and the driving machine can be a motor or a hydraulic cylinder. The working platform is foldable and can meet the need of carrying large objects. When the folding type working platform is in a state of being folded, the folding type working platform is small in occupied space and convenient to move and store.
Description
Technical field
The utility model relates to a kind of workplatform, specifically a kind of collapsible workplatform.
Background technology
In the lifting machinery technical field, the workplatform of elevator or lifting table generally all is that area is fixing, and personnel or equipment are placed on and carry out operation on the lifting table.In general, the area of the area of workplatform and the engineering truck of below is suitable, can move easily.Will require larger workplatform in some occasion, this just needs a kind of folding workplatform of exploitation.
The utility model content
The purpose of this utility model is to provide a kind of collapsible workplatform, and a kind of more large-area working space can be provided.
The technical scheme in the invention for solving the technical problem is: a kind of collapsible workplatform, it is characterized in that, the frame that comprises middle frame and both sides, two frames are articulated in respectively the both sides of middle frame by rotating shaft, middle frame is used for directly connecting with elevator, between middle frame and frame, be respectively equipped with four-bar linkage and driving machine, this four-bar linkage can drive the relative middle frame of frame with driving machine and be rotated jackknife action, and described driving machine can be motor or hydraulic actuating cylinder.
Be provided with at least one row's roller bearing in described middle frame and frame, described roller bearing is driven by the motor that is installed on the middle frame by the chain transmission.
At least one pair of pneumatic or hydraulic pressure is installed in the both sides of described middle frame is stepped up cylinder.
The beneficial effects of the utility model are: workplatform is collapsible, satisfies the carrying of large-sized object, and under the folded state, it is little to take up room, convenient mobile and storage
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is lateral plan of the present utility model;
Fig. 3 is block diagram of the present utility model;
Among the figure: 1 middle frame, 2 frames, 21 rotating shafts, 3 elevators, 4 four-bar linkages, 5 hydraulic actuating cylinders, 6 roller bearings, 61 motors, 7 hydraulic pressure step up cylinder.
The specific embodiment
Such as Fig. 1～shown in Figure 3, a kind of collapsible workplatform comprises the frame 2 on middle frame 1 and both sides, and both all are the rectangle frames that has shaped steel to be welded, and have identical width.2 both sides that are articulated in respectively middle frame by rotating shaft 21 of two frames, two frames can rotate around the shaft.The following of middle frame 1 directly connects for being connected with elevator, between middle frame and frame, be respectively equipped with four-bar linkage 4 and driving machine, wherein driving machine is a hydraulic actuating cylinder 5, and this hydraulic actuating cylinder 5 is the part of four-bar linkage, as shown in the figure, this four-bar linkage can drive the relative middle frame of frame with driving machine and be rotated jackknife action, and this is easy to realize at mechanical field.
Be provided with two row's roller bearings 6 in middle frame and frame, roller bearing is driven by the motor 61 that is installed on the middle frame by the chain transmission, forms so a simple conveyer chain.
At least one pair of pneumatic or hydraulic pressure is installed in the both sides of middle frame 1 is stepped up cylinder 7, can be fixed the article on the platform easily.
Except the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
