Description
Technical Field
[0001] The present invention relates to the technical field of tool carts, and in particular to a multifunctional workshop tool cart and a use method thereof. Background Art
[0002] As a treasure chest for manufacturing workers, workshop tool carts are used in various manufacturing sites, such as automobile manufacturing, shipbuilding, etc., which can provide various conveniences for on-site workers. However, the tool carts in the prior art have a single function, and most of them only have a storage function, lacking support and protection for the working environment of the workers. For example, in shipbuilding operations, there are many welding processes, and welding sparks are sprayed everywhere in the entire workshop, which can easily cause harm to the surrounding personnel. In addition, there is a lot of dust at the work site, and the workers often go home with a head full of dust. In addition, there are a lot of outdoor operations in the shipbuilding industry. In the hot summer, there is no place to shade the sun, or you can only bring an umbrella to shade it. However, the umbrella has no good fixing facilities and cannot automatically adjust the position. It is very laborious to hold it in your hand, and it cannot achieve the ideal sunshade effect when facing the sunlight angles in different directions. If you encounter sudden rain weather, it is even more difficult for an umbrella to play a protective role. Therefore, in response to the above technical problems, there is an urgent need for a multi-functional tool cart, which can not only carry commonly used tools in the workshop, but also provide a stable and safe working environment for workshop workers. When working outside, it can also provide shade and shelter from rain, thereby improving the applicable environment of the tool cart and improving the comfort and satisfaction of workshop workers. Summary of the invention
[0003] In view of this, the purpose of the present invention is to provide a multifunctional workshop tool cart, which can provide a stable and safe working environment for workshop workers by setting up a top shielding component and a surrounding shielding component, improve the safety of workshop workers working in the workshop, and the comfort and satisfaction of working outdoors in hot summer and rainy days.

The connecting rope connects the central hinge points of the arc-shaped connecting rod in series, and the shielding curtain is connected to the connecting rope through multiple rings arranged on the top. The arc-shaped connecting rod can move in a circle to form an arc-shaped structure or a circular structure. The shielding curtain can form a curtain-like structure with an arc-shaped or circular cross-section by following the movement of the arc-shaped connecting rod; the top shielding assembly includes a shielding umbrella, a hinged head, and a limit device. The shielding umbrella is hinged to the top of the electric telescopic rod four through the hinged head. The shielding umbrella can be adjusted from a horizontal state to a vertical state through the hinged head. The limit device can limit the shielding umbrella to keep the shielding umbrella in a vertical state.
[0005] Furthermore, a baffle is provided on the upper part of the multifunctional box, and the baffle is connected to both sides of the multifunctional box by slide rails. The baffle can shield the upper part of the multifunctional box. The energy storage device has an external power socket, which can supply power to small electrical devices such as mobile phones and fans.
[0006] Furthermore, the length of the shielding umbrella is matched with the length of the multifunctional box, and the shielding umbrella is circular when opened.
[0007] Furthermore, the maximum length of the three electric telescopic rods when extended is not shorter than the radius of the shielding umbrella.

[0012] Furthermore, the shielding curtain is composed of a plurality of independent small curtains, one of which is transparent. With this arrangement, the outside environment can be observed when the shielding curtain is closed, thereby improving the comfort of the operator.
[0013] Furthermore, a counterweight and a fixing ring are provided at the lower end of the shielding curtain, and the height of the shielding curtain after vertical extension is not less than 2 meters. Through this arrangement, the shielding curtain can be prevented from being blown up by the wind, thereby losing the shielding effect.
[0014] The present invention also provides a method for using a multifunctional workshop tool vehicle, which is characterized by comprising the following steps:
[0015] Step 1: Control the electric casters to move the workshop tool cart to the target location, clean the site, and fix the workshop tool cart;
[0016] Step 2: Slide the baffle plate and remove it from the multifunctional box to expose the top shielding assembly and the surrounding shielding assemblies. Adjust the shielding umbrella from a horizontal state to a vertical state through a hinge joint, and limit it through a limit device to keep the shielding umbrella in a vertical state. The control device controls the electric telescopic rod three and the electric telescopic rod four to extend, adjust the shielding umbrella to a suitable position and height, and open the shielding umbrella to shield the construction dust layer.
[0017] Step 3: The control device controls the extension of the electric telescopic rod 1 and the electric telescopic rod 2, adjusts the surrounding shielding components to a suitable position and height, adjusts the length and curvature of the arc-shaped connecting rod, and unfolds the shielding curtain vertically and horizontally to form an arc-shaped or circular curtain-like structure. The arc-shaped connecting rod is rotated horizontally to adjust the shielding direction and width of the shielding curtain according to the direction of the surrounding welding sparks, so that the shielding curtain can block the welding sparks, and continues to adjust the height of the electric telescopic rod 2 to raise the shielding curtain to a suitable height. If necessary, use the fixing component to fix the shielding curtain to the ground through the fixing ring;
[0018] Step 4: When the staff needs to work outdoors, adjust the height of the shielding umbrella and the shielding curtain, and cover the shielding umbrella on the shielding curtain so that the shielding umbrella and the shielding curtain form a structure of a small wooden house, thereby forming a temporary semi-enclosed working environment. The semi-enclosed working environment can block wind and sun, improve the comfort of the staff, and improve the working efficiency. When encountering sudden rain and the work cannot be interrupted, the shielding curtain can be adjusted to a circular closed loop structure to form a quasi-enclosed working environment, so as not to affect the continuous work; the staff can observe the outdoor situation through the transparent small curtain, and after the rain stops, the shielding curtain can be adjusted to restore the working environment to a semi-enclosed state;
[0019] Step 5. After use, the controller controls the shielding umbrella and the shielding curtain to descend to a certain height, folds the shielding umbrella and the shielding curtain, adjusts the shielding umbrella and the arc connecting rod back to the initial state, retracts the electric telescopic rods, retracts the shielding umbrella and the shielding curtain into the multi-functional box, and closes the baffle.
[0020] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the multifunctional workshop tool cart of the present invention is more practical than the tool cart of the prior art through the arrangement of the main body, electric casters, energy storage device, tool box, multifunctional box, top shielding assembly, surrounding shielding assembly, supporting device and control device.
