Description
Technical Field
The invention relates to the technical field of steel supports in foundation pit excavation construction, in particular to a maintenance device for a steel support axial force servo system.
Background
At present, when the steel support works, if the steel support system needs to be maintained, the steel support needs to be unloaded, the steel support is maintained after being disassembled, and once the steel support is in a supporting state, if the steel support is unloaded, the steel support can lose the jacking pressure and cannot reach the required position by using the jacking pressure, the maintenance and replacement time is long, the normal operation of construction is influenced, and the whole construction is influenced.
Disclosure of Invention
The invention aims to provide a maintenance device for a steel support axial force servo system, which can adjust the length of a support rod through threads, can realize the adjustment of any length within the engineering requirement range, fully ensure the effective maintenance of the axial force of a steel support during the maintenance of the servo system and is simple and feasible to operate.
The solution of the invention is such that:
the utility model provides a steel shotcrete axle power servo maintenance device, connects the steel crossbeam that outwards stretches out at two terminal surfaces and steel shotcrete or the matching section middle part that steel shotcrete axle power servo is connected, the steel crossbeam is opened there is the through-hole, is provided with the bracing piece that one end inserted the through-hole, the position that the bracing piece inserted the through-hole is opened threadedly, and the screw thread of this department is used for connecting lock nut and bearing nut, and wherein the bearing surface of bearing nut meets with a side end face of steel crossbeam, and the other side end face of steel crossbeam is connected with lock nut's locking end.
The more specific technical scheme also comprises the following steps: the radial direction of the middle part of the matching section is provided with a mounting hole, the steel beam is inserted from the mounting hole, penetrates through the mounting hole and extends out to two sides, and the through hole is arranged at the part of the steel beam extending out from two sides of the mounting hole.
The invention has the advantages that the length of the supporting rod is adjusted through the threads, the adjustment of any length within the engineering requirement range can be realized, the effective maintenance of the axial force of the steel support during the maintenance of the servo system is fully ensured, and the operation is simple and feasible.

The parts of the drawings are detailed as follows: 1. the steel support comprises a steel support main part, 2, a locking nut, 3, a matching joint, 4, a connecting bolt, 5, a bearing nut, 6, a support rod, 7, a steel support axial force servo system, 8, a steel cross beam, 9, a through hole, 10 and a mounting hole.
Detailed Description
As shown in figures 1 and 2, the middle of a matching joint 3 with two end surfaces connected with a steel support or a steel support axial force servo system is connected with a steel beam 8 extending outwards, the steel beam 8 is provided with a through hole 9, a support rod 6 with one end inserted into the through hole 9 is arranged, the part of the support rod 6 inserted into the through hole 9 is provided with threads, the threads at the part are used for connecting a locking nut 2 and a bearing nut 5, wherein the bearing surface of the bearing nut 5 is connected with one side end surface of the steel beam 8, and the other side end surface of the steel beam 8 is connected with the locking end of the locking nut 2.
The structure of the matching joint 3 is shown in fig. 5 and 6, the mounting surfaces at two sides are connected into a whole by welding through supporting steel beams, a mounting hole 10 is formed in the middle in the radial direction, and mounting holes are formed in the mounting surfaces at two sides.
The structure of the steel beam 8 is shown in fig. 3 and 4, the steel beam 8 is welded by adopting a frame structure, and mounting holes 10 are respectively formed at two ends.
The using method of the invention comprises the following steps: when servo needs the maintenance, pass earlier the mounting hole 10 on the matching section 3 with steel crossbeam 8, erection bracing pole 6, lock nut 2 and bearing nut 5, through the elongation value of screw thread regulation bracing piece 6 after that, guarantee that 6 terminal surfaces of bracing piece can effectively bear.
Then the jack of the servo system is returned, and the supporting shaft force borne by the original jack is transferred to the two symmetrical supporting rods. And finally, taking out the connecting bolt for connecting the servo system, and lifting the servo system out of the working surface for maintenance.
