Abstract
Disclosed is a stable jack-up device. In the structure of the utility model, an assistant hydrocylinder (4) is arranged beside a jack-up hydrocylinder (1), the top end of a mandril (5) of the assistant hydrocylinder is provided with a cushion block (6) which can be extended through to the underside of a reaming base (3). The utility model can jack up the goods with different shapes, different weights and different jack-up time requirements stably in a long time, thus various maintenance operations can be more convenient and much safer.
Description
Technical field
The utility model relates to a kind of hydraulic jacking device technical field of structures.
Background technology
Industry-by-industry widely used short travel jacking system in overhaul of the equipments and maintenance mainly relies on the hand-hydraulic jack or utilizes the automatic jacking system of wind oil supercharging at present.Hand-hydraulic jack inefficiency, it is big to take up room, and jack-up is limited in one's ability, is not suitable for the bulky and heavier object of jack-up.And the automatic jacking system of wind oil supercharging is when the heavier object of jack-up, and object is lived in long-time if desired jacking, just must keep the oil pressure of jack-up oil cylinder for a long time.And, make jacking apparatus can not withstand object long-term and stably because the holding time of oil pressure can not be long, brought inconvenience for overhaul of the equipments and handling labor.In the practical application,, the requirement that plays lift, the quantity and the requirement such as jack-up time that hoist a little also are not quite similar, make existing jacking apparatus be difficult to meet the demands just because of usage space, the use occasion difference of jacking system.
Summary of the invention
The purpose of this utility model provides a kind of jacking long-term and stably to live difformity, Different Weight, different top just and plays the object that the time requires, thereby make the stable jacking apparatus that various service works are more convenient and safe in order to solve the deficiency that above-mentioned prior art exists.
The purpose of this utility model is achieved by the following technical solution.
A kind of stable jacking apparatus is to be provided with an auxiliary cylinder on jack-up oil cylinder side, is provided with a cushion block that can reach under the free bearing bottom surface on the push rod top of auxiliary cylinder.
The utility model utilizes cushion block of auxiliary cylinder control, when the jacking of jack-up oil cylinder plays object, cushion block is reached below the free bearing of jack-up oil cylinder push rod, support free bearing, thereby the object that the push rod that relies on cushion block rather than jack-up oil cylinder will be positioned at above the free bearing props up for a long time, efficiently solve owing to can not keep the oil pressure of jack-up oil cylinder for a long time and can not stablize the problem that object is lived in jacking for a long time, make that various service works are more convenient and safe.The utility model is simple in structure, and regulation and control are convenient.
Further set forth content of the present utility model below in conjunction with Figure of description.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is that the utility model is installed the scheme drawing that is used for the jack-up cylinder.
The specific embodiment
As shown in the figure, the utility model comprises jack-up oil cylinder 1, is installed on the free bearing 3 on jack-up oil cylinder push rod 2 tops, is provided with an auxiliary cylinder 4 on jack-up oil cylinder 1 side, is provided with a cushion block 6 that can reach under free bearing 3 bottom surfaces on push rod 5 tops of auxiliary cylinder.Cushion block 6 generally is designed to strip, can be fixedly installed in push rod 5 tops of auxiliary cylinder, turns under free bearing 3 bottom surfaces with push rod 5, also can be horizontally installed in push rod 5 tops, can be along moving laterally under free bearing 3 bottom surfaces.The position control member all is set, with the position of control oil cylinder push rod lifting and rotation on jack-up oil cylinder and auxiliary cylinder.
The utility model can be made into independent instrument and use, and also can be installed on as shown in Figure 3 below the cylinder 10 that needs jack-up.The utility model symmetry is installed on the bracing frame 7, lays stay bearing plate 9 on free bearing 3, cylinder 10 places on the stay bearing plate 9.During jacking cylinder 10, start hydraulic work system, the push rod 2 of control jack-up oil cylinder 1 rises, driving free bearing 3 together rises, with cylinder 10 jack-up, the push rod 5 of HYDRAULIC CONTROL SYSTEM auxiliary cylinder rotates subsequently by stay bearing plate 9, drives the cushion block 6 that is installed on its top and together turns in the space 8 between free bearing 3 and the jack-up oil cylinder, the push rod 2 of jack-up oil cylinder drops to cushion block and is killed by free bearing 3, and cushion block 6 can stable support be lived free bearing 3.If cushion block is to be horizontally installed in push rod 5 tops,, cushion block is moved in the space 8 then along side travel cushion block 6.When needs are fallen cylinder, the push rod 2 of jack-up oil cylinder is risen slightly, rotate auxiliary cylinder 4, cushion block 6 is produced, the push rod 2 of control jack-up oil cylinder descends to putting in place and gets final product.
