Embodiment Construction
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
[0032] The application provides an anti-break telescopic device, which includes a telescopic machine, a load mechanism and a safety mechanism. The telescopic machine includes a telescopic rod, and the main function of the telescopic machine is to provide telescopic power; The mechanism is configured to protect the telescopic rod when the force is overloaded, so as to prevent the curvature of the telescopic rod from exceeding the limit.
[0033] When this embodiment is in use, the telescopic machine can b...

The invention discloses an anti-breaking telescopic device. When the anti-breaking telescopic device is used, when load mechanisms are impacted, impact force is transmitted to telescopic rods through the load mechanisms, and the telescopic rods are impacted. Through overload protection of safety mechanisms, if the loads borne by the safety mechanisms are too large, the safety mechanisms are directly broken or disconnected, after the safety mechanisms are broken or disconnected, the load mechanisms and a telescopic machine cannot extrude the telescopic rods, and therefore the telescopic rods are prevented from being bent, and the overload protection effect on the telescopic rods is achieved. The safety mechanisms can bear the stress generated when the telescopic rods push and pull the load mechanisms, but cannot bear the stress enabling the telescopic rods to generate unrecoverable bending. Due to the fact that the structure of the telescopic machine is quite complex, if the telescopic rods are damaged, the cost for replacing the telescopic rods is high, and the replacement procedure is complex; and the anti-breaking telescopic device avoids the problems, and the telescopic rods can be effectively protected against bending damage in the complex environment.
Description
technical field [0001] The present application relates to the technical field of telescopic mechanical equipment, in particular to an anti-break telescopic device. Background technique [0002] In all walks of life, it is often necessary to use telescoping devices to complete some jobs. The telescopic device generally includes a telescopic machine and a telescopic rod. The telescopic machine is equipped with a motor and some mechanical transmission structures that can drive the telescopic rod to expand and contract. For example, in the spreader equipment, the spreader includes a telescopic machine, and the telescopic rod of the telescopic machine drives the telescopic push-pull of the load beam of the spreader, thereby adjusting the position of the load beam of the spreader to adapt to the installation of various types of goods. During the use of the telescopic machine, it is often necessary to perform telescopic work in some complex and narrow environments. When the extens...
