Description

Technical Field

[0001] The present application relates to the field of construction site tools, and in particular to a two-in-one small-sized climbing device. Background Art

[0002] A cart (transportation tool) is a transport vehicle that is pushed and pulled by manpower. There are single-wheeled, two-wheeled, three-wheeled and four-wheeled carts. The body of a traditional cart is generally made of wood, while the body of a modern cart is generally made of iron. Scaffolding is a tool that assists workers in climbing up and is generally used when workers are working on higher walls.

[0003] Construction sites require transportation tools (such as carts) to transport materials, but common transportation tools only have transportation functions and are relatively simple. Therefore, it is necessary to improve the practicality of transportation tools, increase their functions, and reduce the number of tools. Utility Model Content

[0007] By adopting the above technical solution, when it is necessary to transport items, the ladder frame is stored and partially tilted to make the ladder frame in an inclined state. After that, items are placed on the base, and the base can be pushed to transport materials. The inclination angle of the ladder frame is determined according to the height of the worker; if the worker needs to work at height, the ladder frame is set up and fixed by a fixing component, and the worker can climb onto the ladder frame and step on the pedal. Since the universal wheel has a self-locking function, the base is in a stable state when the worker works at height and will not move, thereby ensuring the safety of the worker when working at height, and the base is easy to move and can be changed to facilitate the worker to continue working at the next work site; the base can also be used as a simple recliner, and the extension frame can be pulled out for the worker's legs to lean on, and the worker can lie on the base to rest. The climbing device (transportation device) can carry materials, assist workers in climbing work, and provide a place for workers to rest. It has many functions and is highly practical, and the number of tools can be reduced.

[0008] Optionally, the ladder frame includes a rotating rod rotatably connected to the base, two frame rods fixed to the rotating rod, and a fixing rod connecting the two frame rods. The pedal is fixed between the two frame rods, and a push rod is provided on the frame rod.

[0009] By adopting the above technical solution, the ladder frame is rotatably connected to the base, which is convenient for setting up for workers to work at height or retracting to carry items.

[0010] Optionally, the fixing component includes a locking rod rotatable on the base and a locking screw provided on the locking rod. A through hole is provided on the locking rod, and a locking hole is provided on the frame rod. The locking screw passes through the through hole and is threadedly connected to the locking hole to fix the ladder frame.

[0011] By adopting the above technical solution, the locking screw passes through the through hole and is threadedly connected to the locking hole to fix the ladder frame, which is convenient for fixing the ladder frame.

[0012] Optionally, the locking screw is provided with a screwing protrusion, and the screwing protrusion is located at the end of the locking screw.

[0013] By adopting the above technical solution, the screwing protrusion is provided to facilitate screwing the locking screw, thereby facilitating fixing or loosening the ladder frame.

[0014] Optionally, the base is provided with a placement protrusion for the locking rod to abut against.

[0015] By adopting the above technical solution, the anti-protrusion is provided for the locking rod to abut against, thereby retracting the locking rod.

[0016] Optionally, the base is provided with a receiving groove for receiving the frame rod.

[0017] By adopting the above technical solution, the receiving groove is provided to receive the frame rod and store the frame rod.

[0018] Optionally, guide protrusions are provided on both sides of the extension frame, and guide grooves for receiving the guide protrusions are provided on the base.

[0019] By adopting the above technical solution, the guide protrusions and guide grooves are provided to guide the movement of the extension frame, which is convenient for pulling out the extension frame from the base, so as to be convenient for workers to lean on their legs when lying on the base to rest.

[0020] Optionally, a moving rod is provided on the base, and the moving rod facilitates the worker to push and pull the base.

[0021] By adopting the above technical solution, the moving rod is provided to facilitate the worker to move the base. The ladder frame can be laid down to increase the carrying capacity, and at this time, the moving rod can be used to transport items.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When transporting items, the storage ladder is retracted and tilted at a certain angle so that the ladder is in an inclined state. Then, place the items on the base, and the base can be pushed to transport materials. The inclination angle of the ladder is determined according to the height of the worker. If the worker needs to work at height, set up the ladder and fix it through the fixing component. The worker can climb onto the ladder and step on the pedal. Since the universal wheels have a self-locking function, the base is in a stable state and will not move when the worker is working at height, ensuring the safety of the worker when working at height. Moreover, the base is easy to move and can change its position to facilitate the worker to continue working at the next work location. The base can also be used as a simple reclining chair. Pull out the extension rack for the worker's legs to lean on, and the worker can lie on the base to rest. This heightening device can transport materials, assist the worker to work at height, and provide a place for the worker to rest. It has multiple functions, high practicality, and can reduce the number of tools;

[0024] 2. Set the locking screw to pass through the through hole and be threadedly connected to the locking hole to fix the ladder, facilitating the fixation of the ladder;

[0025] 3. Set the guiding protrusion and guiding groove to guide the movement of the extension rack, facilitating the pulling out of the extension rack from the base, so as to facilitate the worker to lean on the legs when lying on the base to rest;

[0026] 4. Set the moving rod to facilitate the worker to move the base. The ladder can be laid down to increase the carrying capacity, and at this time, the moving rod can be used to transport items. Description of the Drawings
