[0024] Please refer to Figures 1-9 , the present utility model provides the following technical solutions: A support frame for tunnel engineering measurement, comprising a base plate 1, a sleeve 2, a threaded barrel 3, a gear 4 and a motor 7, further comprising a support mechanism 5 and a bearing plate 6. A measuring device 11 is provided on the top of the base plate 1. Several extension rods 21 are annularly distributed on the bottom surface of the base plate 1. The sleeve 2 is slidably mounted on the extension rods 21. A threaded barrel 3 is provided at the center of the bottom surface of the base plate 1. A threaded rod 31 is mounted on the threaded barrel 3. A mounting plate 12 is mounted on the sleeve 2. A motor 7 is mounted on the mounting plate 12. A gear 4 meshing with the threaded rod 31 and the motor 7 is mounted. A support mechanism 5 is provided in the bottom groove of the sleeve 2;

[0025] The support mechanism 5 comprises a mounting disc 51, a support plate 52, a placement groove 53, a fixed block 54 and a spring 55. The mounting disc 51 is slidably mounted in the bottom groove of the sleeve 2. A groove cooperating with the side wall protrusion of the mounting disc 51 is provided on the side wall of the sleeve 2. Several support plates 52 are hinged on the bottom surface of the mounting disc 51. A placement groove 53 cooperating with the support plates 52 is provided on the bottom surface of the sleeve 2. Fixed blocks 54 are mounted on both ends of the side wall of the bottom groove of the sleeve 2 through several springs 55. A groove cooperating with the fixed blocks 54 is provided on the side wall of the mounting disc 51.

[0026] The bottom plate 1 is used to install the remaining components of the device. The measuring device 11 is used to measure data. The threaded rod 31 is installed on the threaded barrel 3 by means of threads. When the device is in use, the threaded rod 31 is rotated, and the threaded barrel 3 moves along the threaded rod 31 under the action of the threads. At this time, the bottom plate 1 drives the measuring device 11 to rise, thus realizing the adjustment of the height of the device, enabling the device to be applicable to users of different heights. During the rising process of the bottom plate 1, the cooperation between the sleeve 2 and the extension rod 21 plays a limiting role, preventing the threaded barrel 3 and the bottom plate 1 from being driven to rotate by the threaded rod 31 during the rotation of the threaded rod 31, ensuring the working effect of the threaded rod 31. The sleeve 2 increases the grounding area of the device, ensuring the stability of the device during use. The mounting plate 12 is used to install the motor 7 and the threaded rod 31. The motor 7 is connected to the threaded rod 31 through meshing gears 4. The motor 7 can provide power for the rotation of the threaded rod 31, facilitating the user to adjust the height of the device. One end of the threaded rod 31 is installed on the mounting plate 12, ensuring the stability of the threaded rod 31 during the use of the device;

[0027] The side wall protrusion of the mounting disc 51 facilitates the user to move the mounting disc 51. The cooperation between the side wall protrusion of the mounting disc 51 and the mating groove plays a limiting role, preventing the mounting disc 51 from detaching from the sleeve 2 during movement and ensuring the stability of the mounting disc 51 during movement. Several support plates 52 are hinged to the bottom of the mounting disc 51, and placement grooves 53 for mating with the support plates 52 are provided on the sleeve 2. When the mounting disc 51 descends, the support plates 52 extend out of the bottom groove of the sleeve 2 driven by the mounting disc 51, and then the support plates 52 are rotated to a state parallel to the ground. The support plates 52 in the state parallel to the ground increase the grounding area of the device and the position of the outermost end of the grounded part of the device, increasing the stability of the device during use. The placement grooves 53 are used to place the rotated support plates 52. After the support plates 52 are rotated to a state parallel to the ground, they will enter the placement grooves 53. The placement grooves 53 ensure that the deployed support plates 52 do not affect the contact between the sleeve 2 and the ground, ensuring the support effect of the sleeve 2. When the device is idle, the mounting disc 51 is fixed through the cooperation of the side wall groove and the fixing block 54, ensuring the stability of the mounting disc 51 during idleness and transportation of the device. The position of the fixing block 54 ensures that the mounting disc 51 can be fixed through the cooperation between the fixing block 54 and the side wall groove of the mounting disc 51 when the support plates 52 are in the deployed and retracted states, ensuring the stability of the support plates 52 before and after deployment. The side wall shape of the fixing block 54 is an inclined surface that slopes towards the top and bottom side walls of the fixing block 54. During the movement of the mounting disc 51, the fixing block 54 is pushed into the interior of the groove for mounting the fixing block 54, ensuring that the mounting disc 51 is not obstructed during lifting and lowering, and ensuring the working effect of the mounting disc 51. When the fixing block 54 is pushed into the groove for mounting the fixing block 54, the spring 55 is compressed under the action of the moving fixing block 54. As the mounting disc 51 moves, the fixing block 54 enters the interior of the side wall groove of the mounting disc 51 under the action of the spring 55, completing the fixation of the mounting disc 51 by the fixing block 54. Protrusions are provided on the side wall of the fixing block 54, and grooves for mating with the side wall protrusions of the fixing block 54 are provided on the side wall of the mounting fixing block 54. The cooperation between the side wall protrusions of the fixing block 54 and the mating grooves plays a limiting role, ensuring the stability of the fixing block 54 during movement.

[0028] Specifically, a mounting rod 22 is provided on the bottom groove of the sleeve 2, and the mounting disc 51 is slidably mounted on the mounting rod 22. Placement grooves 53 for mating with the support plates 52 are provided on the bottom protrusion of the mounting rod 22.

[0029] The installation rod 22 plays a guiding role to ensure the stability of the installation disc 51 during the movement. The bottom protrusion of the installation rod 22 plays a limiting role, further improving the stability of the installation disc 51 after being installed on the bottom groove of the sleeve 2. The placement groove 53 provided on the bottom protrusion of the installation rod 22 ensures that the bottom protrusion of the installation rod 22 does not hinder the user from removing the support plate 52 from the bottom groove of the sleeve 2.

[0030] Specifically, a protrusion is provided at the bottom of the side wall of the placement groove 53 provided on the bottom protrusion of the installation rod 22, and the cross-sectional shape of the protrusion on the side wall of the placement groove 53 provided on the installation rod 22 is triangular.

[0031] The protrusion on the side wall of the placement groove 53 provided on the installation rod 22 plays a guiding role. During the process of the support plate 52 being removed from the bottom groove of the sleeve 2, the support plate 52 will be pushed by the protrusion on the side wall of the placement groove 53 to rotate outward, facilitating the user to unfold the support plate 52 and improving the efficiency of the user in unfolding the support plate 52. The shape of the protrusion on the side wall of the placement groove 53 ensures the working effect of the protrusion on the side wall of the placement groove 53.

[0032] Specifically, a baffle is provided at the position where the installation disc 51 is hinged to the support plate 52.

[0033] The baffle provided on the installation disc 51 can prevent the support plate 52 from rotating inward, so that the support plate 52 will not be pushed by the fixing block 54 located below the bottom groove of the sleeve 2 during the downward movement, ensuring that the support plate 52 can smoothly pass through the placement groove 53 provided on the installation rod 22 and guaranteeing the working effect of the support mechanism 5.

[0034] Specifically, a disc protrusion is provided on the bottom surface of the extension rod 21, a groove matching the bottom protrusion of the extension rod 21 is provided on the inner wall of the sleeve 2, and the length of the groove on the inner wall of the sleeve 2 is less than the length of the threaded part of the threaded rod 31.

[0035] The cooperation between the bottom protrusion of the extension rod 21 and the groove on the inner wall of the sleeve 2 plays a limiting role, preventing the extension rod 21 from detaching from the sleeve 2 during the movement and ensuring the stability of the extension rod 21 during the use of the device. The length of the groove on the inner wall of the sleeve 2 ensures that when the extension rod 21 moves to the extreme position, the threaded section of the threaded rod 31 is still inside the threaded barrel 3, guaranteeing the stability of the cooperation between the threaded barrel 3 and the threaded rod 31, and thus ensuring the working effect of the threaded rod 31.

[0036] Specifically, a bearing plate 6 matching the gear 4 installed on the threaded rod 31 is installed on the side wall of the sleeve 2. A plurality of balls 61 contacting the side wall of the gear 4 are provided on the opposite side walls of the bearing plate 6, and the depth of the groove on the bearing plate 6 for installing the balls 61 is greater than the radius of the balls 61.

[0037] The bearing plate 6 plays a role in limiting, ensuring the stability of the gear 4 installed on the threaded rod 31 during rotation. The ball 61 provided on the bearing plate 6 reduces the friction suffered by the gear 4 during rotation, thereby reducing the damage suffered by the gear 4 and the bearing plate 6 during the use of the device, extending the service life of the gear 4 and the bearing plate 6. The depth of the groove on the bearing plate 6 for installing the ball 61 can prevent the ball 61 from detaching from the groove on the bearing plate 6 for installing the ball 61 during the use of the device, ensuring the stability of the ball 61 during the use of the device.

[0038] Specifically, the diameter of the gear 4 installed on the threaded rod 31 is larger than the diameter of the gear 4 installed on the motor 7.

[0039] The diameter ratio of the gear 4 installed on the threaded rod 31 and the motor 7 enables the user to accurately adjust the height of the device. The diameter of the gear 4 installed on the motor 7 can also prevent the gear 4 installed on the motor 7 from protruding outside the device, avoiding the user from touching the gear 4 installed on the motor 7 during movement.

[0040] The working principle and usage process of the present utility model: When setting up the device, the mounting plate 51 is moved downward through the side wall protrusion of the mounting plate 51. As the mounting plate 51 moves, the support plate 52 unfolds outward under the action of the side wall protrusion of the placement groove 53 provided on the mounting rod 22. After the mounting plate 51 moves to the extreme position, the support plate 52 is rotated to a state parallel to the ground. When the mounting plate 51 moves, it will push the fixing block 54 into the inside of the groove for installing the fixing block 54, and the fixing of the mounting plate 51 by the fixing block 54 is released. As the mounting plate 51 moves, the mounting plate 51 pushes the lower fixing block 54. When the mounting plate 51 moves to the extreme position, the lower fixing block 54 returns to its original position under the action of the spring 55, and the mounting plate 51 is fixed through the cooperation of the side wall groove and the fixing block 54. The device is placed at the position to be used, and the motor 7 is started. The motor 7 drives the threaded rod 31 to rotate through the meshing gears 4. When the threaded rod 31 rotates, the threaded cylinder 3 rises under the action of the thread, thereby realizing the adjustment of the height of the device.
