Description

Technical Field

[0001] This utility model belongs to the field of engineering measurement technology, specifically, it relates to an engineering measurement height measuring device. Background Technology

[0002] In all stages of modern engineering construction, from project planning and design to construction and acceptance, accurate height measurement is a key element in ensuring project quality and safety. Taking building engineering as an example, the precise measurement of parameters such as building floor height, foundation depth, and verticality directly affects the structural stability and functionality of the building; in road and bridge engineering, the accurate determination of road surface elevation and bridge pier height has a decisive impact on road smoothness, driving comfort, and bridge load-bearing capacity.

[0003] Existing height measuring instruments are mounted on tripods for measurement tasks. However, some existing height measuring instruments cannot be rotated on the tripod after installation. When other engineering measurements are needed, the entire tripod must be rotated to adjust the orientation, which requires readjusting the horizontal position of the equipment. This also makes it inconvenient to adjust the measurement, thus increasing the cumbersomeness of height measuring tasks.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the technical problem that some existing height measuring instruments cannot be rotated on a tripod after installation, requiring the entire tripod to be rotated for adjustments during other engineering measurements, necessitating readjustment of the equipment's horizontal position and increasing the complexity of height measurement tasks, the basic concept of this utility model is as follows:

[0006] An engineering measurement height measuring device includes a support base and a rotating shaft rotatably mounted on the outer wall of the support base. The support base and the rotating shaft are equipped with a rotation disassembly mechanism and an adjustment mechanism.

[0007] The rotary disassembly mechanism includes a rotary support seat rotatably mounted on a support base, on which a measuring instrument is mounted. The rotary support seat is used to drive the measuring instrument to rotate at an angle.

[0008] The adjustment mechanism includes a support adjustment plate connected to the outer wall of the rotating shaft. The support adjustment plate is movably provided with support feet, which are used to adjust the support height of the equipment and adapt to different terrain changes.

[0009] In a preferred embodiment of this utility model, the rotating disassembly mechanism includes a fixed plate connected to the top surface of the rotating support base. A first bolt is threaded onto the outer wall of the fixed plate. A sliding hole is provided on the outer wall of the rotating support base. A spring is connected to the inner wall of the sliding hole. A positioning rod is connected to the end of the spring away from the inner wall of the sliding hole. A connecting rod is connected to the outer wall of one end of the positioning rod. A push plate is connected to the outer wall of the connecting rod.

[0010] In a preferred embodiment of the present invention, the adjustment mechanism includes a limiting groove formed in the inner wall of the support adjustment plate, a limiting slider slidably disposed in the inner wall of the limiting groove, the outer wall of one side of the support foot being connected to the outer wall of the limiting slider, and a second bolt being threadedly connected to the outer wall of the support adjustment plate.

[0011] In a preferred embodiment of this utility model, a retaining ring is engaged on the outer wall of the rotating support base, a positioning hole is provided on the inner wall of the retaining ring, a ball is movably disposed at the bottom end of the retaining ring, and a measuring instrument is connected to the top surface of the retaining ring.

[0012] In a preferred embodiment of this utility model, the end of the positioning rod away from the spring is provided with an inclined surface, and the outer wall of the positioning rod is fitted to the inner wall of the positioning hole.

[0013] In a preferred embodiment of this utility model, the inner wall of the limiting groove is fitted to the outer wall of the limiting slider, and the outer wall of the support foot is fitted to the inner wall of the support adjustment plate.

[0014] In a preferred embodiment of this utility model, a magnetic block is connected to one side of the outer wall of the support adjustment plate, and a magnetic column is connected to the bottom end of the support base.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention utilizes a method where rotating the first bolt disengages it from the support seat, thereby releasing the locking limit of the support seat. This allows the measuring instrument to rotate at an angle, eliminating the need to move and adjust the entire device. This simplifies operation and eliminates the need for significant adjustments to the measuring instrument's horizontal angle after transport, enabling faster measurements and improving measurement accuracy.

[0017] This invention allows for the release of the support foot's compression limit by rotating the second bolt, thereby freeing the support foot from its constraint. The support foot can then be adjusted by pulling it up and down to change its length, thus adapting to different terrains. Magnetic blocks and columns can be used to limit and store the support adjustment plate and support foot, preventing the support adjustment plate from rotating outwards and causing storage inconvenience when not in use.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figures 1 to 5 As shown, an engineering surveying height measuring device includes a support base 1 and a rotating shaft 2 rotatably mounted on the outer wall of the support base 1. A rotation disassembly mechanism 31 and an adjustment mechanism 32 are installed on the support base 1 and the rotating shaft 2. The rotation disassembly mechanism 31 includes a rotating support base 313 rotatably mounted on the support base 1. A measuring instrument 3111 is installed on the rotating support base 313. The rotating support base 313 is used to drive the measuring instrument 3111 to rotate at an angle. The adjustment mechanism 32 includes a support adjustment plate 321 connected to the outer wall of the rotating shaft 2. A support foot 325 is movably mounted on the support adjustment plate 321. The support foot 325 is used to adjust the support height of the device and adapt to different terrain changes.

[0028] Furthermore, the rotating disassembly mechanism 31 includes a fixing plate 311 connected to the top surface of the rotating support 313. The outer wall of the fixing plate 311 is threaded with a first bolt 312. The outer wall of the rotating support 313 has a sliding hole. The inner wall of the sliding hole is connected with a spring 314. The end of the spring 314 away from the inner wall of the sliding hole is connected with a positioning rod 315. The outer wall of the positioning rod 315 is connected with a connecting rod 316. The outer wall of the connecting rod 316 is connected with a push plate 317.

[0029] Furthermore, a retaining ring 318 is engaged on the outer wall of the rotating support 313, a positioning hole 3110 is provided on the inner wall of the retaining ring 318, a ball bearing 319 is movably provided at the bottom end of the retaining ring 318, and a measuring instrument 3111 is connected to the top surface of the retaining ring 318.

[0030] Furthermore, the positioning rod 315 has an inclined surface at the end away from the spring 314, and the outer wall of the positioning rod 315 fits snugly against the inner wall of the positioning hole 3110. Through the inclined surface, the retaining ring 318 can squeeze the positioning rod 315, thereby facilitating the installation of the measuring instrument 3111.

[0031] The adjustment mechanism 32 includes a limiting slide groove 322 formed in the inner wall of the support adjustment plate 321, a limiting slider 324 slidably disposed in the inner wall of the limiting slide groove 322, a support foot 325 connected to the outer wall of the limiting slider 324 on one side of the outer wall, and a second bolt 323 threadedly connected to the outer wall of the support adjustment plate 321.

[0032] Furthermore, the inner wall of the limiting groove 322 is fitted to the outer wall of the limiting slider 324, and the outer wall of the support foot 325 is fitted to the inner wall of the support adjustment plate 321. This improves the tightness of the fit between the support foot 325 and the support adjustment plate 321, thereby enhancing the support stability of the support foot 325.

[0033] Furthermore, a magnetic block 326 is connected to one side of the outer wall of the support adjustment plate 321, and a magnetic column 327 is connected to the bottom of the support base 1. The support adjustment plate 321 and the support foot 325 can be stored and limited by the magnetic block 326 and the magnetic column 327.

[0034] The implementation principle of the engineering measurement height measuring device in this embodiment is as follows: When installing the measuring instrument 3111, first align the retaining ring 318 with the groove at the top of the support base 1, and then push it downwards so that the inner wall of the retaining ring 318 engages with the outer wall of the rotating support base 313. At this time, the inner wall of the retaining ring 318 will contact and squeeze the positioning rod 315. The squeezed positioning rod 315 will move inwards, and at the same time, it will squeeze the spring 314 during the movement. The continued downward movement of 318 will cause the positioning hole 3110 on the inner wall to move downward until the positioning hole 3110 moves to the position of the positioning rod 315. Then, the spring 314 will rebound and push the positioning rod 315 to engage with the positioning hole 3110, thus completing the engagement and installation of the retaining ring 318. In this way, the measuring instrument 3111 can be fixedly installed on the support base 1. During disassembly, simply move the push plate 317 to move the connecting rod 316 inward, which will move the positioning rod 315, causing its outer wall to disengage from the positioning hole 3110. To disassemble the measuring instrument 3111, firstly rotate the first bolt 312 outwards, disengaging one end of the first bolt 312 from the support seat 1, thus releasing the rotation limit of the rotating support seat 313. Then, rotate the measuring instrument 3111 to drive the retaining ring 318 to rotate the rotating support seat 313 on the support seat 1, thereby completing the angle adjustment of the measuring instrument 3111. After adjustment, reverse the first bolt 312, pressing and limiting it against the outer wall of the support seat 1 to complete the positioning. This eliminates the need to move and adjust the angle of the entire device, facilitating operation and avoiding significant adjustments to the horizontal angle of the measuring instrument 3111 after moving the entire device, thus enabling workers to perform measurements quickly and improving measurement efficiency.

[0035] When the length of the support foot 325 needs to be adjusted, first rotate the second bolt 323 to move it outward and release it from the squeezing limit on the outer wall of the support foot 325. Then the support foot 325 can be moved up and down. Through the movement limit of the limiting groove 322 and the limiting slider 324, the support foot 325 can move up and down on the inner wall of the support adjustment plate 321, thereby completing the height adjustment of the equipment to adapt to different terrain changes. The support adjustment plate 321 can be stored by magnetically connecting the magnetic block 326 to the outer wall of the magnetic column 327, preventing the support adjustment plate 321 from rotating outward when not in use, which would cause storage inconvenience.
