Description

Technical Field

[0001] This utility model relates to the field of construction auxiliary device technology, specifically to a fixed device for UWB positioning base stations for construction personnel inside a TBM tunnel. Background Technology

[0002] TBM (Transportation Machine Building) construction methods are being implemented on a large scale, especially in pumped storage power stations in recent years. When construction workers are working inside the tunnel, real-time location tracking is crucial to ensure their safety during TBM construction. Traditional tunnel personnel positioning relies on conventional positioning technologies, whose application inside tunnels is limited; for example, GPS cannot receive satellite signals inside tunnels. With the development of UWB (Ultra-Wideband) technology, UWB base stations have been developed and strategically deployed at intervals within the tunnel to achieve high-precision positioning of personnel inside.

[0003] A UWB base station is a type of base station designed and developed based on Ultra Wide Band (UWB) technology, a wireless carrier communication technology. Its primary function is positioning, similar to GPS satellites, providing a location reference. Combined with positioning tags, it receives location information from the tags via an antenna to achieve precise target positioning. UWB base stations can be installed on TBM (Telematics Machine) equipment. However, the UWB base station and antenna are rigidly fixed to a bracket, with the antenna fixedly connected to the bracket. This means the antenna angle cannot be flexibly adjusted in multiple angles, making its use less flexible and convenient. Utility Model Content

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0028] Example 1:

[0029] like Figures 1 to 3 As shown, this embodiment provides a UWB positioning base station fixing device for construction personnel inside a TBM tunnel, including a first bracket 1 for fixing an antenna 7 and a second bracket 2 for fixing a UWB base station 6. The first bracket 1 and the second bracket 2 are connected at one end with a hollow collar block 11, and the second bracket 2 and the first bracket 1 are connected at one end with a protruding end 21. The first bracket 1 is provided with a positioning hole that matches the protruding end 21. The collar block 11 is fitted onto the protruding end 21 and fixedly connected by a fixing member 3.

[0030] Generally, when constructing inside a TBM tunnel, a UWB positioning base station consisting of two antennas 7 and one UWB base station 6 is used. The two antennas 7 are symmetrically mounted on the first bracket 1. This application describes the installation of one of the antennas 7 as an example.

[0031] In some embodiments, the fixing member 3 is a fixing bolt, and the upper part of the protruding end 21 of the second bracket 2 is provided with a plurality of first threaded holes around its circumference. The collar block 11 is provided with a circular hole corresponding to the first threaded hole. The collar block 11 is locked to the second bracket 2 by fixing bolts passing through the circular hole and the first threaded hole.

[0032] In other embodiments, the fixing member 3 includes a fixing bolt, a clamping block is fixed at one end of the fixing bolt, and a threaded hole matching the fixing bolt is opened on the collar block 11. The fixing bolt passes through the threaded hole, and the clamping block abuts against the protruding end 21 by tightening the fixing bolt.

[0033] Specifically, in order to facilitate the adjustment of the height of the antenna 7, an antenna adjustment assembly 4 is also included. The antenna adjustment assembly 4 includes a connecting rod 41, a hinge seat 42, and a first adjustment rod 43. One end of the connecting rod 41 is fixed to the first bracket 1 by a U-shaped fixing angle bracket, and the other end of the connecting rod 41 is fixedly connected to one end of the hinge seat 42. The other end of the hinge seat 42 is movably connected to the first adjustment rod 43, and the first adjustment rod 43 is fixedly connected to the antenna 7.

[0034] The hinge seat 42 and the first adjusting rod 43 are hinged together by a pin. The hinge seat 42 has a first fixing hole 44 on the outside of the pin, and the first adjusting rod 43 has a second fixing hole corresponding to the first fixing hole 44. The hinge seat 42 and the first adjusting rod 43 are connected by bolts passing through the first fixing hole 44 and the second fixing hole.

[0035] like Figure 3 As shown, in order to adjust the pitch angle of the antenna 7, a pitch adjustment assembly 5 for adjusting the pitch angle of the antenna 7 is also included between the first adjustment rod 43 and the antenna 7. One end of the pitch adjustment assembly 5 is fixedly connected to the first adjustment rod 43, and the other end is movably connected to the antenna 7. The pitch adjustment assembly 5 includes two fixed seats 51, a movable rod 52, and a tightening nut 53. The two fixed seats 51 are symmetrically fixed on the antenna 7. Each fixed seat 51 has a through hole for the movable rod 52 to pass through. Both ends of the movable rod 52 are provided with threads that match the tightening nut 53. The first adjustment rod 43 is fixedly connected to the movable rod 52, and the movable rod 52 is fixed on the antenna 7 by the cooperation of the tightening nut 53 and the movable rod 52.

[0036] like Figure 2 As shown, the second bracket 2 includes a connecting bracket 22, a fixed bracket, and a movable bracket 23. The UWB base station 6 is fixed on the fixed bracket by a U-shaped fixing angle bracket. One end of the connecting bracket 22 is integrally formed with the fixed bracket, and the other end is connected to the fixing plate 24. The fixing plate 24 is provided with screw holes for expansion screws 25 to pass through. One end of the movable bracket 23 is threadedly connected to the fixed bracket, and the other end is provided with a protruding end 21 that is fixedly connected to the first bracket 1.

[0037] Due to limited installation space for the TBM equipment inside the TBM tunnel, the relative position of the first support 1 and the second support 2 can be adjusted by means of a movable support 23. The movable support 23 uses a 304 stainless steel corrugated pipe commonly used in water heaters. This corrugated pipe is bendable and also provides support strength for the first support 1. When installation space on the TBM equipment is limited, the first support 1 can be partially adjusted to another position by bending the movable support 23, instead of having an L-shaped structure with insufficient space utilization. Figure 4 As shown, in order to increase the support strength of the movable bracket 23, two stainless steel corrugated pipes can be installed. A mounting plate is provided on the fixed bracket, and a protrusion connected to the corrugated pipe is provided on the mounting plate. The corrugated pipe and the protrusion are connected by bolts. Similarly, a mounting plate is also provided on the protruding end 21, and a protrusion connected to the corrugated pipe is also provided on the mounting plate. The corrugated pipe and the protrusion are connected by bolts. In this way, the two corrugated pipes of the movable bracket 23 connect the first bracket 1 and the fixed bracket together. By adjusting the bending direction of the corrugated pipe, the relative positional relationship between the first bracket 1 and the second bracket 2 can be adjusted so that the axes of the first bracket 1 and the second bracket 2 do not have to be on the same straight line.

[0038] The usage process of this embodiment is as follows:

[0039] First, fix the connecting rod 41 to the first bracket 1 using the fixed U-shaped angle bracket. Then, observe the installation position on the TBM equipment and align the first bracket 1 with the protruding end 21 of the second bracket 2 through the positioning hole. Fit the collar block 11 onto the protruding end 21. Adjust the circumferential direction until a suitable direction is achieved. Then, fix the first bracket 1 and the second bracket 2 using fixing bolts. Next, adjust the elevation angle of the antenna 7 until a suitable position is achieved. Finally, fix the movable rod 52 by tightening the nut 53. Specifically, if the installation space on the equipment is insufficient, the movable bracket 23 can be adjusted by bending it to a suitable position.

[0040] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
