Description

Technical Field

[0001] The utility model belongs to the technical field of ultra-high-speed low-vacuum construction, and particularly relates to a measurement auxiliary device. Background Art

[0002] The ultra-high-speed low-vacuum tube maglev transportation system uses superconducting magnetic levitation technology to break away from the ground to eliminate frictional resistance, and uses internal near-vacuum pipeline lines to significantly reduce air resistance, thereby achieving "near-ground flight" of more than 1,000 kilometers per hour. It is faster, more convenient, more comfortable, safer and economically controllable, and is the next generation of ultra-high-speed transportation.

[0003] In the actual construction process, since the construction workers are working inside the pipe beam, the construction space inside the pipe beam is small. In the traditional measurement process using a total station, it is necessary to fine-tune the pipe beam prefabricated panels on both sides of the pipe beam. As a result, the total station is affected by the prefabricated panel fine-tuning device 102 during measurement, and the total station cannot observe the targets on the prefabricated panels (see the attached diagram for details). Figure 1 , the dotted line is the surveyor’s line of sight). Utility Model Content

[0004] The embodiment of the utility model provides a measurement auxiliary device, which aims to solve the technical problem in the prior art that a total station cannot observe a target on a prefabricated plate during measurement.

[0005] To achieve the above objectives, the present invention employs a technical solution: providing a measurement assistance device. The measurement assistance device comprises a base plate and a prism mounting frame. The base plate is connected to the precast tubular beam plate; the prism mounting frame is fixed to the base plate, the prism mounting frame being arranged perpendicular to the base plate, and the top of the prism mounting frame is used to place a prism.

[0006] In one possible implementation, the prism mounting frame includes two uprights, a top crossbar, and a bottom crossbar. The two uprights are vertically mounted on the base plate, connected to the base plate, and spaced apart along the length of the base plate. The top crossbar is mounted between the two uprights, with both ends of the top crossbar connected to the tops of the two uprights. The bottom crossbar is mounted between the two uprights, with both ends of the bottom crossbar connected to the bottoms of the two uprights.

[0007] In a possible implementation, the two vertical poles, the top cross bar, and the bottom cross bar surround a cavity, and the prism mounting frame further includes a web embedded in the cavity.

[0008] In a possible implementation, the web is provided with a plurality of weight-reducing holes.

[0009] In a possible implementation, the vertical pole, the top cross bar, and the bottom cross bar are all hollow structures.

[0010] In a possible implementation, the upright pole is connected to the base plate via a detachable connection structure.

[0011] In a possible implementation, the vertical pole is a rod-shaped object whose length direction is adjustable.

[0012] In one possible implementation, the vertical rod includes a first vertical rod, a second vertical rod, and a latch. The first vertical rod is a hollow tubular structure, one end of which is provided with a retaining hole, and the other end of the first vertical rod is connected to the base plate. The second vertical rod is inserted into the first vertical rod, one end of which is provided with a plurality of retaining holes, which are spaced and arranged linearly along the longitudinal direction of the tube body of the second vertical rod, and the other end of the second vertical rod is connected to the prism. The latch is installed in the retaining hole and plugs into the retaining hole to drive the first vertical rod to move relative to the second vertical rod.

[0013] In one possible implementation, the vertical pole includes a central tube, a positive vertical rod, a negative vertical rod, and a locking member. The central tube has internal threads at both ends. The positive vertical rod has external threads at one end, threadedly connected to the central tube via internal and external threads, and its other end is connected to the reaction frame via a detachable connection structure. The negative vertical rod has external threads at one end, threadedly connected to the central tube via internal and external threads, and its other end is connected to the prism. The locking members are located at both ends of the central tube. After the vertical pole is adjusted to the desired length, the central tube and the vertical rod are locked and fixed by adjusting the locking members.

[0014] In a possible implementation, the vertical pole, the top cross bar, and the bottom cross bar are all made of aluminum alloy.

[0015] In the embodiment of the present application, compared with the prior art, first, the worker installs the base plate and the prism mounting frame into one piece, then vertically connects the base plate and the tubular beam prefabricated plate, adjusts the central axis of the prism mounting frame to be parallel to the horizontal plane, and finally installs the prism on the top of the prism mounting frame. The total station measures the prism coordinates on the top of the prism mounting frame to obtain the relative coordinates of the prism at that location; since the overall length of the prism mounting frame and the base plate are relatively fixed, the accurate coordinates of the tubular beam prefabricated plate at that location can be obtained by calculation, thereby solving the technical problem in the prior art that the total station cannot observe the target on the prefabricated plate during measurement.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, and "several" means one or more, unless otherwise specifically defined.

[0027] Please also refer to Figure 2 Now, a measurement auxiliary device provided by the utility model is described.

[0028] The measurement auxiliary device includes a base plate 1 and a prism mounting frame 2. The base plate 1 is connected to the precast tubular beam plate 100. The prism mounting frame 2 is fixed to the base plate 1, and is arranged perpendicular to the base plate 1. The top of the prism mounting frame 2 is used to place a prism 103.

[0029] Compared to the prior art, the measurement assistance device provided in this embodiment first integrates the base plate 1 and the prism mounting frame 2. Next, the base plate 1 is vertically connected to the tubular beam precast panel 100, and the central axis of the prism mounting frame 2 is adjusted to be parallel to the horizontal plane. Finally, the prism 103 is mounted on top of the prism mounting frame 2. The total station 101 measures the coordinates of the prism 103 on top of the prism mounting frame 2 to obtain the relative coordinates of the prism 103 at that location. Because the overall length of the prism mounting frame 2 and the base plate 1 are relatively fixed, the accurate coordinates of the tubular beam precast panel 100 at that location can be obtained through calculation, thereby resolving the technical problem in the prior art where the total station 101 cannot observe the target on the precast panel during measurement.

[0032] The top crossbar 22 and the bottom crossbar 23 connect the two vertical poles 21 into a whole. The surveyor can measure the relative coordinates of the ends of the two vertical poles 21 in actual measurement. The surveyor compares the X, Y and Z values of the two relative coordinates. When the X and Y values of the two relative coordinates are exactly the same, and only the Z value has a height difference, and the height difference is the relative distance between the central axes of the two vertical poles 21, it can be determined that the central axis of the prism mounting frame 2 is horizontal ( Figure 2 The dotted line in the figure is the surveyor’s line of sight).
