Abstract

The invention belongs to the field of civil engineering construction, and particularly relates to a jacking device which comprises a base, jacking nuts, a jacking screw rod and a jacking steel pipe. The jacking device is suitable for installing large components of a fabricated building, improving and increasing the floor height of the existing building and locally heightening the building. The jacking screw rod passes through the base and the jacking steel pipe; the jacking screw rod makes contact with the base by the jacking nut, and the jacking screw rod makes contact with the jacking steel pipe by the other jacking nut; the upper part of the jacking screw rod is in right hand thread, and the lower part of the jacking screw rod is in left hand thread. Jacking is directly carried out by combining a thick threaded rod and a wrench, so that the device is simple and adjustable in jacking force.

Description

A kind of self-locking mechanical type jacking apparatus
Technical field
the invention belongs to Construction of Civil Engineering field, refer more particularly to jacking apparatus. be applicable to the installation of assembled architecture large-scale component and reconstruction of existing building increase floor height and structures part are increased.
Background technology
in recent years, along with the lasting expansion with construction scope that deepens constantly of building industry system reform, the feature that building industrialization relies on it can improve construction efficiency, promote architecture quality, low-carbon energy-saving, meet sustainable development becomes the effective way that building is transformed the mode of development.
in the middle of fabricated structure work progress, people usually need prefabricated components carry out jacking and installed, but common jacking apparatus is difficult to guarantee stationarity and the precision of jacking process, and work efficiency and degree of automation are relatively low.
Summary of the invention
the present invention, in order to make up the defect of prior art, provides a kind of steady, accurate self-locking mechanical type jacking apparatus.
in order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
a self-locking mechanical type jacking apparatus, comprises base, jacking nut, jacking screw rod, jacking steel pipe.Wherein, jacking screw rod, through base and jacking steel pipe, contacts by nut between jacking screw rod and base, between jacking screw rod and jacking steel pipe, by jacking nut, contacts, and jacking screw rod top is divided into right-hand thread, and bottom is divided into left-hand thread.
advantage of the present invention is: by the mode that adopts coarse thread bar to add spanner, directly carry out jacking, device is simple, and top lift is adjustable.
Accompanying drawing explanation
fig. 1 is schematic diagram of the present invention.
in figure: 1, base, 2, jacking nut, 3, jacking screw rod, 4, jacking steel pipe.
The specific embodiment
below in conjunction with drawings and Examples to the present invention's detailed explanation in addition.
as shown in Figure 1: the present invention is mainly comprised of base 1, jacking nut 2, jacking screw rod 3, jacking steel pipe 4, nut 5.
jacking jacking screw rod 3 of the present invention, through base 1 and jacking steel pipe 4, contacts by nut 5 between jacking screw rod 3 and base 1, between jacking screw rod 3 and jacking steel pipe 4, by jacking nut 2, contacts, and jacking screw rod 3 tops are divided into right-hand thread, and bottom is divided into left-hand thread.
principle of work of the present invention:
need the member of jacking to be connected with jacking steel pipe 4 by backing plate, during work, by pulling jacking nut 2, drive jacking steel pipe 4 and then can realize the jacking to member.In jacking process, jacking screw rod 3 rotates along with the rotation of jacking nut 2, and the left-hand thread of jacking screw rod 3 partly drives nut 5 to rotate, and reaches the effect of self-locking.
finally it should be noted that: although the present invention is had been described in detail with reference to previous embodiment, but for a person skilled in the art, in the situation that not making creative work, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.

Claims (3)

1. a self-locking mechanical type jacking apparatus, is characterized in that, described self-locking mechanical type jacking apparatus comprises base 1, jacking nut 2, jacking screw rod 3, jacking steel pipe 4, nut 5.
