Abstract
The utility model discloses a hydraulic quick-jacking device, which comprises a base, a hydraulic cylinder body and a driving rod arranged in the hydraulic cylinder body, wherein the driving rod projects from the hydraulic cylinder body. The hydraulic quick-jacking device is characterized in that a base cover is fixed on the base, N extension covers which are sequentially sheathed from inside to outside are arranged in the base cover, a positioning mechanism is respectively arranged between every two adjacent extension covers, a supporting table is integrally arranged at the upper end part of the first extension cover, an installing surface is integrally arranged at the bottom of the Nth extension cover, an installing hole is arranged in the installing surface, and the hydraulic cylinder body extends into the installing hole. The hydraulic quick-jacking device has the advantages that when the heights of the ordinary jack and other jacking tools are not enough at the places with higher altitudes, the extension covers which are sequentially sheathed can be pulled out by hands to be positioned so as to increase the height of the jacking device, then the extension covers are jacked by a hydraulic mechanism to support heavy things, and the large-distance jacking and expanding functions can be quickly realized.
Description
Technical field
The utility model relates to a kind of support expansion tool, relates in particular to the quick jacking apparatus of a kind of fluid pressure type.
Background technology
In daily life and some disaster reliefs (as traffic accident, earthquake, landslide etc.), we often can use the support expansion tool, so that weight propped up or expand and obtain an activity space.Lifting altitude is low, lifting velocity is slow for common in the market support expansion tool (stretching instrument as tops such as jacks), uses inconvenience even can't use in some highly higher occasions.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of quick jacking apparatus of fluid pressure type that can realize the support the planning function of big distance in highly higher occasion apace.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the quick jacking apparatus of a kind of fluid pressure type, comprise base, hydraulic cylinder and the drive spindle that is arranged in the described hydraulic cylinder, described drive spindle passes described hydraulic cylinder, be set with cover for seat on the described base, described cover for seat is set in outside the described hydraulic cylinder, be provided with the from inside to outside extension set of socket successively of N in the described cover for seat, N 〉=2, and N round numbers, be provided with detent mechanism between two adjacent extension sets, the upper end of first extension set has been wholely set brace table, the height of first extension set is greater than the height of second extension set, the bottom of N extension set has been wholely set attachment face, and described attachment face is provided with mounting hole, and described hydraulic cylinder stretches in the described mounting hole.
Described detent mechanism comprises button and locating piece, described locating piece is set in place on the lower end side of the extension set of inboard, described locating piece and described between the extension set of inboard apical grafting spring is arranged, the described upper side that is positioned at the extension set in the outside is provided with knock hole, described button stretches out described knock hole, the inner of described button has been wholely set positioning boss, described positioning boss apical grafting is in described knock hole, in working order down, described locating piece stretches into location in the described knock hole.
The described inside face of extension set that is positioned at the outside is provided with axial and described knock hole to the guide groove that is communicated with, described locating piece and described guide groove bearing fit.
The both sides of described brace table are provided with the recess that conveniently pulls, and described recess is positioned at the top of second extension set.
Be wholely set bracing frame in the described cover for seat, under off working state, the attachment face on described N the extension set is supported on the described bracing frame, to eliminate the holding capacity of hydraulic efficiency gear part drive spindle under off working state.
Compared with prior art, the utility model has the advantages that owing to be provided with the from inside to outside extension set of socket successively of N in the cover for seat, higher in some aspect ratios, and stretch under the height situation far from being enough of instrument on common tops such as jack, the first extension set of socket successively of available hand is pulled out the location to increase the height of jacking apparatus, by hydraulic gear jack-up extension set weight is supported then, realize the support the planning function of big distance apace; And extension set as long as inwardly pin button, makes locating piece break away from knock hole and gets final product when resetting.
