Technical Field

[0001] The utility model belongs to the technical field of limit alarm devices, in particular to a limit alarm device for tunneling in a steel sleeve of a shield machine. Background Art

[0002] A shield machine is a special engineering machinery for tunnel excavation. However, it needs to be monitored when the shield machine is working to ensure its normal operation. The limit alarms currently used are mostly fixed with threads. This connection method has great limitations and cannot be fixed according to connecting pipes of different diameters, which greatly reduces the installation efficiency of the equipment and the practicality of the equipment. The threaded connection will greatly increase the possibility of the equipment falling off. Therefore, a limit alarm device for excavation in the steel sleeve of a shield machine is proposed. Utility Model Content

[0003] The purpose of the present utility model is to provide a limit alarm device for excavating in the steel sleeve of a shield machine, by setting a fixed component, specifically, rotating the knob 212 clockwise to drive the rotating shaft 1 215 to rotate, and the rotation of the bevel gear 1 216 will drive the two bevel gears 217 to rotate relative to each other, and at the same time, the two threaded rods 218 will drive the clamping plates 214 to move away from each other through the rotation of the bevel gear 217 and clamp and fix the inside of the connecting pipe 114, thereby completing the installation of the probe 115, solving the problem that the shield machine is a special engineering machinery for tunnel excavation, but the shield machine needs to be monitored when it is working to ensure its normal operation. Most of the limit alarms currently used are fixed by threads, and this connection method has great limitations. It cannot be fixed according to connecting pipes of different diameters, which greatly reduces the installation efficiency of the equipment and the practicality of the equipment. In addition, the threaded connection will greatly increase the problem of the equipment falling off.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The utility model provides a limit alarm device for excavating in a steel sleeve of a shield machine, comprising a main frame mechanism, the main frame mechanism comprising a steel sleeve, a shield machine being arranged inside the steel sleeve, a fixing assembly being arranged on the front face of the steel sleeve, and an anti-slip assembly being arranged on the outside of the fixing assembly, the fixing assemblies being in four groups, and the four groups of fixing assemblies comprise the same parts, the fixing assembly comprising a supporting frame, a bevel gear 1 being arranged inside the supporting frame, a rotating shaft 1 being fixedly connected to the front face of the bevel gear 1, a knob being arranged on the front face of the supporting frame, a back face of the knob being fixedly connected to the front face of the rotating shaft 1, an outer surface of the bevel gear 1 being meshed and connected to two bevel gears 2, an outer surface of the rotating shaft 1 being rotatably connected to the inner front face of the supporting frame, and clockwise rotation of the knob drives the rotating shaft 1 to rotate, and the rotation of the bevel gear 1 drives the two bevel gears 2 to rotate relative to each other, and at the same time, the two threaded rods drive the clamps to move away from each other through the rotation of the bevel gear 2 and clamp and fix the inside of the connecting pipe, thereby completing the installation of the probe.

[0006] Furthermore, the two bevel gears are fixedly connected to a threaded rod on one side away from each other, and the two threaded rods are rotatably connected to the top and bottom of the support frame on the other side. The outer surfaces of the two threaded rods are threadedly connected to a splint, and the front of the steel sleeve is fixedly connected to four support blocks, and the corresponding sides of the four support blocks are fixedly connected to connecting pipes, and the outer surfaces of the four connecting pipes are fixedly connected to a fixed frame, and a probe is fixedly connected to the left side of the support frame.

Spring 2 is fixedly connected to the inside of the two disc springs, and a push block is fixedly connected to the left side of the two disc springs. At the same time, the disc spring drives the push block to exert force on the nut through the rebound force of spring 2, thereby preventing the nut from loosening due to shaking, thereby causing the equipment to fall off.

When the spring 1 312 shrinks, the fixing plate 311 can be successfully sleeved on the outside of the support rod 315. Then the staff tightens the nut 313 and the support rod 3 318 is a kind of screw threaded fastener, and the screw threaded fastener 313 is fixed on the support rod 315 ... When the nut 313 is turned counterclockwise to disengage from the support rod 315, the limit plate 319 is affected by the rebound force of the spring 1 312 to pop out the fixing plate 311, which is convenient for the staff to disassemble, greatly improving the work progress and greatly reducing the labor of the staff.
