[0029] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] The utility model is described in detail below in conjunction with the accompanying drawings. The embodiment discloses a fixed support frame for subway measurement and monitoring equipment, such as Figure 1 As shown, it includes a support platform 1, a measuring device body 2 is fixedly installed in the middle position of the top of the support platform 1, an adjusting sleeve 3 is fixedly connected to the bottom of the support platform 1, the adjusting sleeve 3 is threadedly connected to the first threaded rod 4, a stable support block 6 is fixedly installed at the bottom of the first threaded rod 4, a circular fixing block 7 is fixedly installed on the outer surface of the adjusting sleeve 3, a plurality of telescopic sleeves 8 are fixedly installed on the circular fixing block 7, and the telescopic sleeves 8 are threadedly connected to the second threaded rod 9; a dustproof structure is also provided on the top of the support platform 1, which can wrap the measuring device body 2 inside to prevent the measuring device body 2 from being affected by dust in the air when not in use.

[0031] In this embodiment, if Figure 1 , Figure 2 , Figure 3 As shown, the dustproof structure includes two first square fixing blocks 10 fixedly installed on the front and rear sides of the top surface of the support platform 1, and the first movable door 11 is movably connected to the two first square fixing blocks 10 on the same side; it can be understood that a movable door mounting hole is provided in the middle of the first square fixing block 10, and movable door rotating shafts are provided on both sides of the bottom end of the first movable door 11, and the movable door rotating shafts are set in the movable door mounting holes, thereby limiting the first movable door 11 to rotate only relative to the first square fixing block 10.

[0032] It should be noted that the first movable door 11 is a square plate, and its bottom end is in contact with the top surface of the support platform 1. When the first movable door 11 is perpendicular to the support platform 1, the side surface of the support platform 1 and the first movable door 11 are in the same longitudinal plane, which makes the first movable door 11 rotate toward the side away from the measuring device body 2 when it is perpendicular to the support platform 1.

[0033] In this embodiment, if Figure 1 , Figure 2 , Figure 3 As shown, two second square fixing blocks 12 are fixedly installed on the left and right sides of the top surface of the support platform 1, and the second movable door 13 is movably connected to the two second square fixing blocks 12 on the same side. It can be understood that a movable door mounting hole is also provided in the middle of the second square fixing block 12, and movable door rotating shafts are also provided on both sides of the bottom end of the second movable door 13. The second movable door 13 is also a square plate, and its bottom end is also in contact with the top surface of the support platform 1.

[0034] It can be understood that the first square fixing block 10 and the second square fixing block 12 are of the same size. Since the length and width of the measurement device body 2 are mostly inconsistent, the support platform 1 is mostly designed as a rectangle. The inconsistent length and width of the support platform 1 result in different distances between the two first square fixing blocks 10 and the two second square fixing blocks 12. This also causes the widths of the first movable door 11 and the second movable door 13 to be different, while their lengths are the same.

[0035] In this embodiment, as Figure 1 , Figure 3 shown, a cover plate 14 is provided at the top of the first movable door 11 and the second movable door 13. The cover plate 14 is a "concave" plate. When both the first movable door 11 and the second movable door 13 are perpendicular to the support platform 1, the cover plate 14 houses the tops of the first movable door 11 and the second movable door 13, restricting the outward rotation of the first movable door 11 and the second movable door 13, thereby realizing the enclosure of the measurement device body 2. It can be understood that a handle 15 is fixedly installed at the top of the cover plate 14. By a staff member holding the handle 15 and removing the cover plate 14 from the tops of the first movable door 11 and the second movable door 13, the first movable door 11 and the second movable door 13 can be opened, so as to use the measurement device body 2. Conversely, by combining the first movable door 11 and the second movable door 13 and using the cover plate 14 to cover the measurement device body 2, the function of dust-proof protection can be achieved, thereby realizing the function of dust-proof protection and effectively improving the service life of the measurement device body 2.

[0036] It can be understood that the measurement device body 2 can be engineering surveying instruments such as a theodolite, a level, a plane table, a rangefinder, a tachymeter, a gyrotheodolite, a laser measuring instrument, a total station, a camera, a measuring instrument, a mapping instrument, a projector, etc.

[0037] In this embodiment, as Figure 4 shown, the inside of the adjusting sleeve 3 is hollow and is provided with a first internal thread groove 5, and the first internal thread groove 5 is used in matching with the first threaded rod 4. By rotating the adjusting sleeve 3, the stable support block 6 is moved away from or close to the adjusting sleeve 3. Since the stable support block 6 is supported on the ground, by rotating the adjusting sleeve 3, the height of the support platform 1 relative to the ground can be adjusted.

[0038] Since the scale is prone to wear and disappear, in this embodiment, the height is controlled by the equidistant measurement holes, that is, a plurality of measurement holes 41 with the same spacing are provided on the first threaded rod 4. Since the pitch of the thread on the first threaded rod 4 (i.e., the axial distance between the corresponding points of two adjacent teeth on the thread) is fixed and is a known quantity, one measurement hole 41 is provided for every plurality (not limited here considering different pitches in actual applications) of pitches, and the distance between every two measurement holes 41 must be the same; the measurement holes 41 start from the end of the stable support block 6 far from the tip, and the distance from the stable support block 6 to the center of the first measurement hole 41 is equal to the distance between the centers of every two measurement holes 41; scale lines are provided on the stable support block 6, and the height of the stable support block 6 above the ground can be clearly known.

[0039] It can be understood that when the height of the support table 1 relative to the ground needs to be adjusted, the height of the stable support block 6 is considered first. If the tip of the stable support block 6 is inserted into the ground, then the height of the stable support block 6 above the ground is considered first; when the adjustment sleeve 3 is rotated, observe how many measurement holes 41 are away from the stable support block 6. Since the spacing between every two measurement holes is known, the pitch is known, and the length of the adjustment sleeve 3 is known, the height of the support table 1 relative to the ground can be known according to the number of measurement holes 41 exposed on the first threaded rod 4 and the pitch.

[0040] In this embodiment, as Figure 1 shown, three telescopic rods 8 are evenly arranged along the circumference of the circular fixing block 7. It can be understood that a second internal thread groove (not shown in the figure) is provided inside the telescopic rod 8, and the second internal thread groove is used in cooperation with the second threaded rod 9. In this embodiment, the stable support block 6 is a conical structure, and the bottom end of the second threaded rod 9 is also provided with a balance support block 91 with a conical structure.

[0041] In this embodiment, the staff firmly fixes the stable support block 6 by inserting it into the ground or places the tip of the stable support block 6 on the control point of the hard ground; then the staff holds the adjustment sleeve 3 and rotates it to adjust the relative height relationship between the adjustment sleeve 3 and the first threaded rod 4, and adjusts the height of the support table 1 relative to the ground to control the height of the instrument and equipment relative to the ground; after the height adjustment is completed, the staff holds the second threaded rod 9 and rotates it to move the balance support block 91 away from the telescopic rod 8, inserts the three balance support blocks 91 into the ground or places the tips of the balance support blocks 91 on the hard ground to stably support the whole, and then the measuring device body 2 can be used for measurement work; it can not only effectively support the measuring device body, but also directly observe and adjust the height, effectively improving the practicability of the measuring device body.

[0042] Although the specific implementation manners of the present utility model have been described above in conjunction with the accompanying drawings, they do not limit the protection scope of the present utility model. Those skilled in the art should understand that various modifications or deformations that can be made without creative efforts on the basis of the technical solution of the present utility model are still within the protection scope of the present utility model.
