Description

Technical Field

[0001] The utility model relates to the technical field of prism mounts, in particular to an assembled laser prism mount. Background Art

[0002] In engineering survey applications, it is necessary to mark the plane positions of the buildings (structures) designed on the drawings on the ground. This work is called setting out. Using a total station for setting out is a common means in engineering practice. There are usually two ways to set out with a total station. One is the polar coordinate method for setting out, and the other is the coordinate method for setting out. Among them, the coordinate method for setting out is the most commonly used method. When using the total station coordinate method for setting out, first, the instrument station is set up and oriented. After inputting the coordinates of the point to be set out, the azimuth of the point to be set out is obtained. According to the azimuth, the sighting direction of the total station is turned, and the setting-out personnel are instructed to place the setting-out prism rod in the line of sight direction of the total station. The distance and angle between the prism and the instrument station are measured to determine the position of the point to be set out.

[0003] According to the theoretical distance between the point to be set out and the instrument station, the setting-out distance deviation is obtained. The setting-out personnel hold the prism rod and move it back and forth, left and right along the line of sight direction of the total station until the distance and angle deviations are zero. In order to accurately determine the position of the point to be set out, every time the prism mount is moved, the total station has to measure the distance between the prism and the instrument station again and inform the setting-out personnel of the distance deviation of the point to be set out. The setting-out personnel repeatedly adjust the moving azimuth and moving distance according to the instructions. However, in the traditional prism mount setting-out process, repeatedly moving the prism mount not only increases the time cost of the setting-out process, but also affects the point position accuracy when the point position is determined and the prism mount is moved away to do other things.

[0028] Furthermore, scale lines 203 are arranged on both the crossbeam track 201 and the movable crossbeam 202.

[0029] Specifically, the assembled laser prism holder mainly consists of support legs 1, a movable disk 2, and a telescopic prism rod 3. The support legs 1 are composed of two movable inclined rods 101 and a fixed vertical rod 102. Both the movable inclined rods 101 and the fixed vertical rod 102 can be disassembled from the movable disk 2. The fixed vertical rod 102 is fixedly connected to the movable disk 2. The universal ball head 1011 is snap-connected to the movable disk 2, facilitating quick assembly and disassembly for on-site operations. The length of the fixed vertical rod 102 is 120 cm. Together with two movable inclined rods 101 with lengths of 150 cm - 180 cm, the movable disk 2 is leveled. The horizontal bubble 6 can observe the horizontal state of the movable disk 2. The mounting tube 2021 on the movable crossbeam 202 supports the telescopic prism rod 3. The telescopic prism rod 3 is inserted into the mounting tube 2021, and its position can be fixed with bolts. The telescopic prism rod 3 can move horizontally by 10 cm within the crossbeam track 201 and vertically by 10 cm on the movable crossbeam 202. The movable disk 2 has scale lines 203 both longitudinally and horizontally for understanding the adjusted displacement distance. The length of the movable tube 302 of the telescopic prism rod 3 is 105 cm, and it can move vertically by 100 cm within the support prism sleeve 301. The top of the telescopic prism rod 3 is inserted and installed with the prism through the prism buckle 303, and the prism buckle 303 and the prism can also be fixed with bolts. The power control box 4 can use No. 5 batteries as the power source. A switch for controlling the laser emitter to emit a laser beam is provided on the power control box 4. The laser beam is directed towards the ground along the movable tube 302. Figure 1 The dotted line on the lower side of the movable tube 302 is the optical path of the laser beam.
