Referring to fig. 1 to 4, the tripod 200 for construction survey has the following working principle:
the tripod 200 for construction survey includes a connection stage 210, a table 220, a connection assembly 230, an adjustment assembly 240, and a stand assembly 250.
Wherein, the connection table 210 is connected with the workbench 220 through the connection assembly 230; the end surface of the workbench 220 far away from the connecting platform 210 is provided with a working surface 221 for mounting the measuring instrument; the stand assembly 250 is coupled with the coupling stage 210 to support the coupling stage 210.
In use, the measuring instrument is mounted on the work surface 221, and the levelness of the work surface 221 is adjusted through the cooperation of the connecting assembly 230, the adjusting assembly 240 and the stand assembly 250, so as to ensure that the levelness of the work surface 221 meets the requirement of the measuring instrument on the levelness.
Specifically, in the process of adjusting the levelness of the working surface 221, the working height of the table 220 can be adjusted by the supporting function of the stand assembly 250. Meanwhile, the connection assembly 230 includes a locking pipe joint 231 and a square cone joint 232 which are respectively connected with the connection table 210 and the workbench 220, and the locking pipe joint 231 is respectively connected with the square cone joint 232 through corresponding matching of four connection studs 233 and four fixing screw holes 234, so that after the four connection studs 233 are correspondingly matched with the corresponding fixing screw holes 234, each connection stud 233 extends into the locking pipe joint 231 and is adjusted in length with the square cone joint 232 in abutting joint, and the levelness of the workbench 220 connected with the square cone joint 232 can be adjusted.
In addition, in the process of adjusting the levelness of the workbench 220 by connecting the locking pipe joint 231 with the square cone joint 232, the position of the abutting block 242 slidably connected with the movable turntable 241 relative to the workbench 220 is adjusted by rotating the movable turntable 241, and then the abutting force between the abutting block 242 and the workbench 220 can be adjusted by rotating the rotating stud 243, so that the workbench 220 is driven to rotate relative to the locking pipe joint 231 by the abutting action of the abutting block and the workbench 220, and the levelness of the working surface 221 is adjusted.
Therefore, through the above adjusting mode, in the process of adjusting the levelness of the working surface 221 of the working table 220, the levelness of the working surface 221 is accurately adjusted through the abutting action of the connecting stud 233 and the square cone joint 232 and the abutting action of the abutting table and the working table 220. In addition, the adjustment mode is simple, the adjustment is convenient, and the adjustment efficiency can be effectively improved.
It should be noted that, in the process of arranging the connection assembly 230, the locking pipe joint 231 of the connection assembly 230 is provided with an installation cavity corresponding to the square cone joint 232, when the square cone joint 232 is installed, the square cone joint 232 is inserted into the installation cavity of the locking pipe joint 231, then the four connection studs 233 are respectively matched with the four fixing screw holes 234 in a one-to-one correspondence manner, and the connection studs 233 are rotated, so that the four connection studs 233 are abutted against the square cone joint 232 located in the installation cavity after being inserted into the installation cavity, and the square cone joint 232 can be relatively fixed in the locking pipe joint 231, thereby determining the relative position between the connection table 210 and the workbench 220; in addition, by adjusting the length of the four connecting studs 233 extending into the mounting cavity of the locking pipe joint 231, the connection angle of the pyramid joint 232 relative to the locking pipe joint 231 can be adjusted, and further, the levelness of the working surface 221 can be adjusted.
In setting the adjustment assembly 240, the adjustment assembly 240 functions to make precise adjustments to the levelness of the work surface 221. The reason for this is that, in the process of adjusting the levelness of the working surface 221 through the four connecting studs 233, the connecting studs 233 at the adjusting positions need to be unscrewed, and the working platform 220 needs to be pulled by an external force, so as to adjust the levelness of the working surface 221, that is, in the process of adjusting the working surface 221 by the connecting assembly 230, the working platform 220 needs to be pulled by the external force, so as to adjust the levelness, and therefore, when the levelness of the working surface 221 is adjusted by the connecting assembly 230, the difficulty of adjusting the levelness of the working surface 221 within a certain range is low, and the operation is convenient; the precise adjustment of the levelness of the working surface 221 by the connecting assembly 230 is difficult, time-consuming and labor-consuming.
Secondly, the four first limiting holes 212 correspond to the four fixing screw holes 234 one by one, and the axis of each first limiting hole 212 and the axis of the corresponding fixing screw hole 234 are located in the same vertical plane; and around the axial direction of the movable turntable 241, the axial line of the second limiting hole 246 is 90 degrees apart from the axial line of the slideway 247; in this way, the purpose of the arrangement is to provide a position corresponding to each connection stud 233 by the rotation of the movable dial 241, so that the cooperation between the limit pin 244 and the first limit hole 212 and the second limit hole 246 determines that the abutting block 242 can adjust the levelness of the working surface 221 in the direction at the position corresponding to the connection stud 233, so as to accurately overcome the levelness error of the working surface 221 in each direction. Moreover, since the axial line of the second position-limiting hole 246 is spaced from the axial line of the slide way 247 by 90 °, when the movable turntable 241 is rotated, the movement of the position-limiting pin 244 does not interfere with the movement of the abutting block 242 because the second position-limiting hole 246 engaged with the position-limiting pin 244 is spaced from the slide way 247.
In summary, when the levelness of the working surface 221 is adjusted by the connecting assembly 230, the levelness of the working surface 221 is adjusted within a certain range with low difficulty, and the operation is convenient. Therefore, in the embodiment of the present invention, it is adopted that the levelness of the working surface 221 is adjusted within a certain range by the connection assembly 230, and then the levelness of the working surface 221 is precisely adjusted by the adjustment assembly 240.
Referring to fig. 1 to 4, the tripod 200 for construction survey is adjusted as follows:
the deviation between the levelness of the working surface 221 and the target levelness is measured by a measuring instrument or a horizontal bubble on the working surface 221, the adjusting direction of the working surface 221 is determined, then the connecting stud 233 in the corresponding direction is unscrewed, the limit pin 244 is pulled to separate the limit pin 244 from the first limit hole 212, the movable turntable 241 is rotated to rotate the abutting block 242 to the corresponding direction, then the rotating stud 243 is rotated to abut the abutting block 242 with the workbench 220, so that the abutting table applies external force to the workbench 220 to drive the workbench 220 to rotate in the direction with the deviation until the levelness deviation in the direction disappears, and after the deviation disappears, the connecting stud 233 in the direction is screwed, at the moment, because the abutting table abuts against the workbench 220, and under the action force of the thread fit of the rotating stud 243 and the abutting table, the abutting table and the rotating stud 243 have a self-locking function, at the moment, the position of the holding-down stage may be constant.
Similarly, if the levelness in the other direction needs to be adjusted, the adjustment process is as above, but it should be noted that, when the levelness deviation in one direction disappears due to the abutting action of the abutting table, and the abutting table needs to be rotated to the next direction by rotating the movable turntable 241, the connecting studs 233 in the previous direction all need to be kept in the abutting state with the square cone joints 232.
Further, in this embodiment, when the slide ways 247 are disposed, in order to facilitate the installation of the abutting block 242 and facilitate the threaded connection between the rotating studs 243 and the abutting block 242, at least one sliding groove matched with the abutting block 242 is formed in the side wall of the slide ways 247 along the radial direction of the movable turntable 241 and the radial direction of the movable turntable 241, and the sliding groove is used for guiding the abutting block 242 to move along the radial direction of the movable turntable 241. A first mounting portion and a second mounting portion are disposed in the slideway 247, the first mounting portion and the second mounting portion are respectively located at two ends of the slideway 247 in the extending direction, and both the first mounting portion and the second mounting portion are rotatably connected with the rotating stud 243.
In addition, when the work table 220 is abutted by the abutting block 242 to support and adjust the work table 220, the adjusting assembly 240 further includes a rotating handle 249, the rotating handle 249 is connected with one end of the rotating stud 243 close to the second mounting portion and is located outside the slideway 247, and the rotating handle 249 is used for driving the rotating stud 243 to rotate in the slideway 247 under the action of external force, so as to facilitate the operation of a measurer.
Further, in the present embodiment, in order to adjust the levelness of the working surface 221, at least one level bubble for measuring the levelness of the working surface 221 is disposed on the working surface 221. The working surface 221 is provided with at least one mounting groove for mounting the horizontal bubble.
In this embodiment, in order to determine the relative position of the movable turntable 241 with respect to the connecting stud 233, four first scale marks are provided on the outer circumferential surface of the body, the four first scale marks are sequentially arranged around the central axis of the body at intervals, the four first scale marks correspond to the four first limiting holes 212 one by one, and the axis of each first limiting hole 212 and the corresponding first scale mark are located in the same vertical plane; the outer peripheral surface of the movable turntable 241 is provided with a second scale mark, and the second scale mark and the axis of the first limiting hole 212 are located in the same vertical plane. And because the four first position-limiting holes 212 correspond to the four fixing screw holes 234 one to one, and the axis of each first position-limiting hole 212 and the axis of the corresponding fixing screw hole 234 are located in the same vertical plane.
By the arrangement mode, the relative position of the movable turntable 241 can be conveniently determined, and then the position of the abutting table is determined, namely when the first scale mark and the second scale mark are located on the same vertical plane, the axis of the first limiting hole 212 and the axis of the second limiting hole 246 are located on the same vertical plane. The position of the abutting table corresponds to the position of one of the connecting studs 233, and the movement of the abutting block 242 along the extension direction of the slideway 247 can drive the worktable 220 to move in the corresponding direction after abutting against the worktable 220, so that the levelness of the working surface 221 in the direction can be accurately adjusted.
Further, referring to fig. 3-4, in the present embodiment, in order to reduce the rotational friction between the movable turntable 241 and the connection column 211, a bearing mounting portion is disposed on the outer circumferential surface of the connection column 211, a rotational bearing 236 is disposed between the mounting hole 245 and the mating surface of the connection column 211, and the movable turntable 241 is rotatably connected to the connection column 211 through the rotational bearing 236. Second, when the bearing mounting portion is provided, the bearing mounting portion is spaced from the first position-limiting hole 212 in order to prevent the position of the rotary bearing 236 from affecting the fit between the position-limiting pin 244 and the first position-limiting hole 212.
In the present embodiment, in order to improve the connection stability between the connection table 210 and the table 220, the central axis of the locking pipe joint 231 coincides with the central axis of the connection table 210, and the central axis of the square cone joint 232 coincides with the central axis of the table 220.
