Abstract
The utility model provides a tunnel steel arch frame jacking device, which comprises a support leg, wherein the support leg is provided with a lower support rod and an upper support rod; a threaded rod is arranged at the upper end of the lower support rod; a threaded rod with opposite screw threads is arranged at the lower end of the corresponding upper support rod; a threaded sleeve is correspondingly sleeved on the threaded rods; a U-shaped slot matched with a steel arch frame is arranged on the top end of the upper support rod; and a disk stressing device is arranged at the middle position outside the threaded sleeve. The tunnel steel arch frame jacking device utilizes the stressing disk to jack the positive and opposite screw threads and to simultaneously screw in or screw out the upper and lower support rods; therewith, the steel arch frame jacking device is shortened or prolonged, thereby complementing steady elevation and accurate aligned connection between the steel arch frame jacking device and the steel arch frames on the two sides; only three persons are needed for operation and control, therefore, the labor is greatly saved and the labor intensity is reduced; simultaneously, lots of unsafe factors are reduced as well; and the tunnel steel arch frame jacking device is steady and labor-saving, achieves aligned connection, is flexible to regulate, is accurate and convenient, is simple in structure, easy to process, low in cost and convenient to carry, and has high applicability and high work efficiency.
Description
Technical field
The utility model relates to the tunnel construction technical field, is specifically related to a kind of tunnel steel arch frame lift-up device.
Background technology
At present, along with building on a large scale of infrastructure such as special line for passenger trains and high-grade highway, the footpath construction of tunnel of striding greatly under unfavorable geological condition also gets more and more.Present tunnel all adopts the New Austrian Tunneling Method construction, and the benching tunnelling method excavation is adopted in unfavorable geology location not only section, and its preliminary bracing is also used the steel bow member instead by general grid.Because the span in tunnel is big, the steel bow member is all taked three sections spellings, and in the end during the bow member of spelling vault sections, way is to be realized connecting with the contraposition of both sides steel bow member by number human manual elevations usually.There is following defective in this way; One is to use manpower many, and labour intensity is big; The 2nd, the effort of taking a lot of work when contraposition is regulated, the difficult control of precision, efficient is low; The 3rd, also can increase some unsafe factors in the operation.
Summary of the invention
The purpose of the utility model just provides a kind of convenience simple in structure, light and handy, easy operating, and contraposition is regulated flexibly, is easy to control the tunnel steel arch frame lift-up device of aligning accuracy again.
The technical scheme of the utility model does for this reason, and the tunnel steel arch frame lift-up device comprises a supporting leg, and supporting leg is provided with lower fulcrum bar; And be provided with upper rack posts, it is characterized in that: be provided with threaded rod in described lower fulcrum bar upper end, corresponding upper rack posts lower end is provided with the opposite threaded rod of screw thread; Correspondence is with threaded sleeve on the threaded rod; The top of upper rack posts is provided with the U type draw-in groove that is complementary with the steel bow member.
Improvement to such scheme is: the outer centre position of said threaded sleeve is provided with augmentor.
Improvement to such scheme is: said augmentor is afterburning disk.
Beneficial effect:
The utility model is because the fixing steel bow member of the U type draw-in groove that utilizes upper rack posts; The supporting leg of lower fulcrum bar is flat in operating platform or the arch and reserves on the core soil; Make positive left-hand thread jacking with afterburning disk, upper and lower pole screws in simultaneously or screws out, and steel bow member lift-up device then shortens or elongation thereupon; With this steady up-down and accurately contraposition that drives vault sections steel bow member, realization connects with its both sides steel bow member; Only need three people to control, the steel bow member that can carry out the vault sections connects with the accurate contraposition of both sides steel bow member, greatly saves manpower and reduces labor intensity, and also reduces many unsafe factors simultaneously; Not only steadily laborsaving, contraposition connects, regulates flexibly, and is accurately convenient; Moreover be exactly that this apparatus structure is simple, be easy to processing, with low cost, easy to carry, applicability is big, high efficiency.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the user mode sketch map of the utility model.
Among the figure 1 is supporting leg, the 2nd, lower fulcrum bar, the 3rd, afterburning disk, the 4th, threaded sleeve, the 5th, upper rack posts, the 6th, U type draw-in groove, the 7th, steel bow member, the 8th, threaded rod the, the 9th, threaded rod two.
The specific embodiment
The utility model such as Fig. 1, as shown in Figure 2.
The tunnel steel arch frame lift-up device comprises a supporting leg 1, and supporting leg 1 is provided with lower fulcrum bar 2; And be provided with upper rack posts 5, and lower fulcrum bar 2 upper ends are provided with threaded rod 1, and corresponding upper rack posts 5 lower ends are provided with the opposite threaded rod of screw thread 29; Correspondence is with threaded sleeve 4 on threaded rod 1, the threaded rod 29; The top of upper rack posts 5 is provided with the U type draw-in groove 6 that is complementary with the steel bow member.
Threaded sleeve 4 outer centre positions are provided with afterburning disk 3.
The utility model is when frame stands and promote steel bow member 7; Positive and negative threaded rod 1, threaded rod 29 with lower fulcrum bar that processes 2 and upper rack posts 5 screws in the threaded sleeve 4 earlier; Accomplish the connection of whole lift-up device; And rotate afterburning disk 3, treat that test running is normal after, be transported to the location of the upright steel bow member 7 of tunnel domestic demand frame.
During concrete operations, reserving core soil in will encircleing earlier needs the position leveling and the cushioning at placement supporting leg 1 place solid, then this device is erected; And transfer to suitable height; With artificial the steel bow member 7 of vault sections is lifted to the U type draw-in groove 6 of upper rack posts 5 subsequently, treat steel bow member 7 in U type draw-in groove 6, fall the position stable after, by the afterburning disk 3 of people's turn; Other arranges two people to control the two ends of steel bow member 7 respectively; Through the rotation and lifting of screw thread, realize the accurate contraposition of steel bow member 7 like a cork, realization connects with both sides steel bow member.In addition, the space is bigger in arch, when the stroke of steel bow member lift-up device is not enough, also can satisfy top journey needs with this through the position at supporting leg 1 place is increased.
