A lift trolley

technical field

The utility model relates to the technical field of transportation equipment, more specifically, it relates to a lifting trolley.

Background technique

Trolley is a transport vehicle pushed and pulled by manpower, which can work in places where motor vehicles are inconvenient to use, and carry lighter goods in a short distance.

The Chinese patent with the existing publication number CN206749848U discloses a height-adjustable load trolley, which includes a movable platform, a trolley support frame and a handrail, and the lower end of the handrail is fixedly connected with the trolley support frame, and also includes scissors. Fork mechanism, screw rod and rocker, the scissor mechanism is composed of two sets of opposite upper scissor arm mechanisms and two opposite lower scissor arm mechanisms, the upper scissor arm mechanism and the lower scissor arm mechanism are hinged, and the opposite The hinge point of the upper scissor arm mechanism and the lower scissor arm is connected together by the scissor arm support shaft, the screw rod is rotatably installed on the scissor arm support shaft, and the rocking bar is fixedly installed on the tail end of the screw mandrel.

In the above technical solution, the operator manually shakes the rocker to drive the screw to rotate, so as to realize the extension of the scissor arm, so that the movable platform can be raised and lowered, thereby adjusting the height of the movable platform, which is inconvenient to operate. In addition, the operator It is tiring to bend over and carry goods for a long time. At this time, the height of the movable platform needs to be adjusted according to the height of the goods, which increases the labor intensity of the operator.

Utility model content

Aiming at the problem that the operator needs to bend down to manually adjust the height of the movable platform in practical application, and the operation is inconvenient, the purpose of this utility model is to propose a lifting trolley. After the objects are placed on the loading platform, the loading platform can be lowered by itself , so as to reduce the workload of operators, the specific scheme is as follows:

A lifting trolley, comprising a support frame, sliding wheels and a loading platform arranged on the support frame, a sliding plate is arranged between the support frame and the loading platform, and the loading platform is slidably connected to the loading platform The sliding plate is provided with a lifting mechanism arranged in pairs, and the lifting mechanism includes a fixed wheel, a counterweight and a winding rope, and the fixed wheel is installed on the end of the sliding plate away from the support frame. The winding rope is wound on the fixed wheel and one end is connected to the counterweight, and the other ends of the two winding ropes are connected to the loading platform.

Through the above technical solution, when no items are placed on the loading platform, the loading platform is at the end of the sliding plate away from the support frame, and the counterweight is at the end of the sliding plate close to the support frame, so that the operator can easily place the items on the sliding plate without bending over. On the loading platform, after the items are gradually placed on the loading platform, under the action of the gravity of the items, the winding rope starts to rotate around the fixed wheel, the counterweight gradually moves away from the support frame, and at the same time the loading platform gradually approaches the support frame. As a result, more items can be placed on the loading platform, and the transportation efficiency of the trolley is improved each time. The operator does not need to manually adjust the height of the loading platform, which saves labor and reduces the labor intensity of the staff.

Further, the sliding plate is provided with a cavity, the lifting mechanism is installed in the cavity, a guide slide is provided in the cavity, a sliding block is slidably connected to the guide slide, and the sliding block extends The cavity is connected with the loading platform.

Through the above technical solution, the lifting mechanism is installed in the cavity as a whole, avoiding the collision between the lifting mechanism and external objects, resulting in damage; in addition, when the counterweight drives the loading platform to move, the loading platform slides stably along the guide slide plate through the sliding block To avoid the tilting of the loading platform and the spilling of items.

Through the above technical solution, the sliding plate is detachably connected as a whole, which facilitates the installation or removal of the guide slide plate in the cavity and the adjustment of the counterweight.

Further, a connection block is connected to the end of the winding rope away from the counterweight, the connection block is slidably connected to the C-shaped plate, and the connection block is connected to the loading platform.

Through the above technical solution, the counterweight is connected with the connecting block through the winding rope, and the connecting block slides on the C-shaped plate, which further limits the smooth sliding of the loading platform on the guide plate and avoids skewing.

Further, the counterweight includes more than two counterweights, and the two winding ropes are respectively connected to the two counterweights.

Through the above technical solution, after the item is placed on the loading platform, the generated gravity interacts and balances with the gravity of the counterweight, so that the counterweight limits the loading platform to be stable on the guide slide and will not slide down suddenly.

Further, the two counterweights are connected to each other.

Through the above technical solution, the two counterweights jointly exert a pulling force on the loading platform, so that the two connecting blocks can slide on the C-shaped plate synchronously, avoiding that the height of the connection between the loading platform and the connecting block is different, causing the loading The platform is askew.

Further, the counterweight is slidably connected to the C-shaped plate.

Through the above technical solution, the counterweight slides stably on the C-shaped plate during the movement away from the support frame, thereby improving the stability of the movement of the counterweight, thereby improving the stability of the movement of the loading platform.

Further, guide rails are fixedly connected to the C-shaped plates, and both ends of the counterweight in the length direction slide on the guide rails.

Through the above technical solution, the counterweight slides on the guide rail, and the counterweight is slidably connected to the C-shaped plate, thereby improving the stability of the counterweight movement.

Further, a loading board is embedded on the support frame.

Through the above technical solution, when the object platform is in the middle of the slide guide, different types of objects can be placed on the object loading plate at this time, reducing the time for operators to separate the objects in the later stage, thereby improving work efficiency.

Compared with the prior art, the beneficial effects of the utility model are as follows:

(1) By setting the lifting mechanism on the support plate, after the object is placed on the loading platform, under the action of the gravity of the object, the winding rope starts to rotate around the fixed wheel, the counterweight gradually moves away from the support frame, and the loading platform gradually Close to the support frame, so that more items can be placed on the loading platform, without the need for the operator to manually adjust the height of the loading platform, reducing the labor intensity of the staff;

(2) By setting the loading board on the support frame, different types of items can be placed on the loading board, reducing the time for operators to separate items in the later stage, thereby improving work efficiency.
