And be fit for various different chain saw tests, the upgrading requirement of chain saw safety test has been accomplished to the low cost.
Description
Technical Field
The utility model relates to the technical field of chain saw suspension safety testing equipment.
Background
Because of convenient use, manual chain saws are increasingly popular with consumers and widely used throughout the world. The export of manual chain saws in our country has been in a continuously growing state for the past few years and has been scaled up in the european market, which is one of two markets worldwide, but has caused a certain restriction to the export of the product due to incomplete safety testing capabilities.
The safety test certification is realized, and the complete test capability of European and American standard safety certification of the product is established, wherein one important safety index is that the chain saw suspension test must meet the performance requirement of the standard test. However, both domestic manufacturers and domestic and foreign authorities lack sufficient research and development for the equipment for chain saw suspension testing. The existing devices with different positions and directions are needed to be adjusted and installed again, and the method is time-consuming, inconvenient to operate and has great uncertainty on test results. On the other hand, the requirements of some test standards are continually increasing and improving. For example, new standards now require testing lifting suspensions, with existing testing equipment, which can only be lifted manually, then lifted with the aid of a lifting truck, with low efficiency, and which require a large test site to be occupied.
In order to increase the ability to adapt to standards while at the same time saving costs as much as possible, it is necessary to develop a new chain saw suspension testing device to meet new testing requirements.
Disclosure of Invention
The utility model aims to solve the defects of the prior art and provides a novel chain saw suspension testing device and a special lifting mechanism.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the lifting mechanism comprises a hydraulic cylinder, a connecting rod, a piston rod and a vertical cylinder sleeve, wherein the hydraulic cylinder comprises an oil pump, a vertical oil cylinder and an oil cylinder piston rod, the piston rod is arranged in the vertical cylinder sleeve, and the top ends of the piston rod and the oil cylinder piston rod are fixedly connected through the connecting rod.
Further, the stroke of the cylinder piston rod and the piston rod is 50-850 mm.
Further, the hydraulic cylinder with the cylinder diameter of more than 90 mm is selected as the hydraulic cylinder.
Further, the lifting mechanism further comprises a base, and the hydraulic cylinder and the vertical cylinder sleeve are respectively fixed on the base, so that the whole lifting mechanism is convenient to transfer to a test site.
The existing chain saw suspension testing device is fixed on the lifting mechanism piston rod 3 of the novel chain saw suspension testing device capable of stably moving up and down is formed.
The utility model has the beneficial effects that:
the hydraulic cylinder is adopted to serve as the upward thrust of the suspension chain saw, so that the lifting force is large, the stability is good, and the safety and the reliability are realized; meanwhile, the cylinder sleeve and the piston rod are in parallel linkage, so that stable operation and accurate positioning of the suspension chain saw are further ensured.
In addition, a matched lifting mechanism is added to the existing chain saw suspension testing device, only fixed connection is needed, and replacement or improvement of existing testing equipment is not needed; and be fit for various different chain saw tests, the upgrading requirement of chain saw safety test has been accomplished to the low cost.
In general, the novel chain saw suspension testing device provided by the utility model has the advantages of stable lifting, safety, reliability, accurate positioning, small occupied area and capability of completely meeting various testing requirements of the standard.
The technical scheme of the utility model is illustrated in the following by referring to the attached drawings and examples.
