specific Embodiment approach

[0061] In order to further illustrate the technical solution of the present invention, in conjunction with the accompanying drawings, the specific implementation of the present invention is as follows:

[0062] The purpose of the present invention is to provide a large-scale gantry equipment stepped beam crawling lifting device, which is used to complete the stepped lifting of heavy objects, mainly to meet the working requirements of the stepped beam above 30T. The driving of the overall lifting device comes from the oil supply of the hydraulic station. The control mechanism of the hydraulic station completes the control of the oil supply volume and oil supply speed of each hydraulic actuator, so that the hydraulic actuator can complete the corresponding action. In order to be more accurate To complete the lifting movement, each actuator is equipped with a displacement sensor, a force sensor, and a servo valve body to ensure sufficient displacement of the piston rod of the actu...

Abstract

The invention discloses a large gantry equipment stepped beam crawling and lifting device. The large gantry equipment stepped beam crawling and lifting device consists of a vertical lifting platform assembly body, hydraulic actuator moving arm assembly bodies and gantry stand column support platform assembly bodies, wherein the hydraulic actuator moving arm assembly bodies are symmetrically hinged onto two sides of the vertical lifting platform assembly body; the vertical lifting platform assembly body is arranged between the two gantry stand column support platform assembly bodies; a platform parking support shaft and a guide rail are arranged on the front side of each gantry stand column support platform assembly body along the vertical direction; and the hydraulic moving arm assembly bodies are clamped on the platform parking support shafts to drive the vertical lifting platform assembly body to lift and move along the guide rails. By adopting the large gantry equipment stepped beam crawling and lifting device, upper beam lifting work with self-set speed can be realized; and furthermore, the device is provided with positioning locking devices and falling-prevention safety devices, so that the working reliability of a heavy duty lift is greatly improved, and the working stability is ensured.

Description

technical field [0001] The present invention relates to a large-scale gantry equipment beam elevating device, more precisely, the invention relates to a large-scale gantry equipment stepped beam crawling elevating device. Background technique [0002] At present, under the influence of the national macro-control policy, my country's industry is developing rapidly, especially the construction machinery industry has shown an unprecedented prosperity. This has also led to the rapid development of hoisting machinery technology, making the development direction of hoisting machinery gradually tend to be hydraulic, integrated, large-scale, and functional. However, this still cannot make up for the technical gap between domestic and foreign countries. The development of foreign elevators is earlier than domestic elevators, and the technology of elevators is more high-end, mature and perfect. The current foreign development trend of elevators is: large-scale heavy-duty products, pro...
