Description

Karakuli unpowered reciprocating self-propelled vehicle

The present invention relates to a Karakul force unpowered load-carrying reciprocating self-propelled vehicle, in particular to a reciprocating self-propelled vehicle technology that can realize the Karakul force function through the construction of toggle-type linkage and energy storage reciprocating traction mechanism .

According to what we know, the term "Karakuli" is directly translated in Japanese, which means "ingenious machinery". Generally speaking, "Karaku force" refers to a non-power transmission mechanism designed directly using physical principles such as gravity, levers, or machinery in an environment that does not use electricity. The more common method of applying Karakuli is to use the unpowered transmission mechanism as the self-propelled driving source of the self-propelled unmanned truck or the self-propelled lifting platform to make up for the failure of the automated transportation system or the automated storage system. Although the conventional Karakuri self-propelled vehicle has the advantage of self-propelled function without consuming electric energy in the area of the dead corner of conveying goods, its kinetic energy accumulation mechanism is mostly realized by a scroll-type spring mechanism, so that the required composition The components are relatively numerous and complex, which leads to the lack of higher manufacturing costs.

Furthermore, after a patent search, it is found that the previous patents related to this case are the patents shown in the national model announcement No. M571334 "Power traction device that can be combined with unpowered carts or trolleys", which includes the provision of a speed controller , The speed controller is electrically connected to a battery, the battery is located behind the speed controller, the motor is located beside the speed controller, the motor is electrically connected to the aforementioned speed controller and the battery, the motor power is connected to the reducer, and the reducer is combined with the motor shaft. At the front end, the drive shaft is set to reduce Below the speed machine, the reducer is equipped with an output shaft, the output shaft is fixed with a first transmission sprocket, and a passive first sprocket is fixed on the transmission shaft. The chain connects the transmission first sprocket and the passive first sprocket, and the two parts of the transmission shaft At the end, the first wheel and the second wheel are respectively provided to form a modular power traction device; although the patent only needs to develop one of the aforementioned power traction devices, which can be applied to all the aforementioned unpowered carts or trolleys for combined assembly; This patent does not have the self-propelled function of Karakuli, so it must be driven by batteries and motors to achieve the purpose of driving the cart or trolley, which causes inconvenience and difficulty in use.

In view of this, the above-mentioned conventional Karakuli self-propelled vehicle technology and the aforementioned patent are indeed not perfect, and there is still a need for further improvement, and based on the urgent needs of related industries, the inventors have made continuous efforts Under the research and development, finally developed a set of the present invention which is different from the above-mentioned conventional technology and the previously disclosed patent.

The first objective of the present invention is to provide a Karakuli unpowered load-carrying reciprocating self-propelled vehicle. The Karakuli function is realized by the construction of toggle-type linkage and energy-storage reciprocating traction mechanism, and thus has a self-propelled Functions without the need for power consumption, labor saving, reduced labor costs, and relatively streamlined components and reduced manufacturing costs. The technical means to achieve the aforementioned first objective include a frame, a lifting platform, a toggle linkage mechanism, an energy storage reciprocating traction mechanism, and a runner mechanism. The lifting platform is arranged on the frame to move up and down. When the loading platform carries the weight of the article, the lifting platform moves down relative to the frame, and drives the toggle-type linkage mechanism to accumulate kinetic energy to drive the wheel mechanism on the frame to move forward. A certain distance in one direction, when the item is removed without downward pressure, the toggle-type linkage mechanism releases the accumulated kinetic energy to drive the lifting platform to move up relative to the frame, and then drive the wheel mechanism on the frame to the opposite direction Go some distance.

The second object of the present invention is to provide a device with counting Karakuli unpowered reciprocating self-propelled vehicle with overweight warning and other functions. The technical means to achieve the aforementioned second objective include a frame, a lifting platform, a toggle linkage mechanism, an energy storage reciprocating traction mechanism, and a runner mechanism. The lifting platform is arranged on the frame to move up and down. When the loading platform carries the weight of the article, the lifting platform moves down relative to the frame, and drives the toggle-type linkage mechanism to accumulate kinetic energy to drive the wheel mechanism on the frame to move forward. A certain distance in one direction, when the item is removed without downward pressure, the toggle-type linkage mechanism releases the accumulated kinetic energy to drive the lifting platform to move up relative to the frame, and then drive the wheel mechanism on the frame to the opposite direction Go some distance. It further includes a signal processing module, a displacement sensing module, and a load meter arranged in the second rail to sense the load weight of the article when the first rail is loaded to generate a weight sensing signal. When the lifting platform moves from top to bottom relative to the frame, the displacement sensing module generates a displacement sensing signal, which is interpreted and processed by the signal processing module and then calculated as a frequency value. The accumulated number of times can be obtained in a preset time period. The signal processing module converts and processes the weight sensing signal into a weight value, and compares it with a preset weight value. When the weight value is higher than the set weight value, it outputs a warning signal to issue a warning through a warning device.
