Description

Technical Field

[0001] This utility model relates to the field of leveling instrument technology, and more specifically to a support device for an engineering surveying leveling instrument. Background Technology

[0002] In the field of engineering surveying, the level instrument, as a core device for accurately measuring elevation differences, is widely used in scenarios such as building construction, road construction, and topographic mapping. Its measurement accuracy directly affects the quality of engineering construction and subsequent acceptance results. The stable operation of the level instrument is highly dependent on the support device. The support device must have the functions of stably fixing the level instrument, flexibly adjusting its height, and adapting to the movement requirements of different working environments to ensure that the level instrument can maintain accurate measurement even under complex working conditions (such as uneven ground on the construction site and frequent changes in measurement points).

[0003] According to research, most of the common engineering surveying level support devices on the market are based on tripod structures. Some improved support devices may add simple manual adjustment mechanisms or basic fixing components. Although some level support devices have been optimized in terms of stability or ease of adjustment, they still do not fully solve the multiple pain points in actual operation, and there is still room for improvement in the overall structural design and functional adaptability.

[0004] The shortcomings of existing technologies: Most existing support devices use a single clamping or bolt fixing method, which makes it difficult to form a uniform and stable enclosure and limit for the level and rotating parts. In addition, some fixing structures lack protective design, which can easily cause hard wear to the equipment during clamping. At the same time, the level is prone to displacement when subjected to external vibration or slight collision, affecting the measurement accuracy.

[0005] Therefore, there is a need to provide a support device for engineering surveying level instruments to solve the problems mentioned above. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an engineering surveying level support device to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: an engineering surveying level support device, including a level body, a bracket fixedly connected to the bottom end of the level body, a rotating platform fixedly connected to the bottom end of the bracket, lifting limit rods fixedly connected to both sides of the bottom end of the rotating platform, a base fixedly connected to the bottom end of the two lifting limit rods, universal self-locking wheels fixedly connected to the four corners of the bottom end of the base, and three square sliding grooves opened near the middle of the bracket;

[0008] The support device for the engineering surveying level also includes:

[0009] A limiting component is provided at the bracket and is used to limit and fix the rotary table under the support of the bracket;

[0010] A height adjustment component is disposed inside the base and between the bottom of the rotating platform, for adjusting the height of the rotating platform and the level instrument body;

[0011] Preferably, the limiting component includes:

[0012] Two cylinders are located inside the bracket near the top. A connecting rod is fixedly connected between the two ends of each cylinder. A fixed support is fixedly sleeved in the middle of the left connecting rod, and the top of the fixed support is fixedly connected to the top of the inner wall of the bracket. A movable support is fixedly sleeved in the middle of the right connecting rod, and a slider is fixedly attached to the top of the movable support. A main guide rod is movably sleeved at the bottom of the slider through a movable column. A turntable is movably sleeved at the other end of the main guide rod through a movable column. The top center of the turntable is rotatably connected to the middle of the bracket through a rotating column.

[0013] A secondary guide mechanism is located at the opposite corner of the turntable, and rotates accordingly as the turntable rotates.

[0014] Preferably, the secondary guide mechanism includes two secondary guide rods, the opposite ends of the two secondary guide rods are movably connected to the diagonal of the turntable via movable columns, the opposite ends of the two secondary guide rods are each movably connected to a slider via a movable column, and the top ends of the three sliders are each fixedly connected to a clamping block.

[0015] Preferably, the outer walls of the three sliders are slidably connected in a square groove, and protective pads are fixedly connected to the opposite sides of the three clamping blocks. The three protective pads are made of soft rubber anti-slip material, and the rotating platform is disposed between the three protective pads.

[0016] Preferably, the height adjustment component includes:

[0017] A limiting post is provided, with its bottom end fixedly connected to the inner bottom end of the base. A driven bevel gear is movably sleeved on the top end of the limiting post via a bearing. A screw is fixedly connected to the middle of the driven bevel gear. The outer wall of the screw is movably sleeved with the base. A threaded sleeve is threaded onto the outer wall of the screw. The top end of the threaded sleeve is fixedly connected to the middle of the bottom end of the rotary table.

[0018] A drive mechanism is provided on the outer wall of the driven bevel gear and is used to drive the driven bevel gear to rotate the screw.

[0019] Preferably, the driving mechanism includes a drive motor, the bottom end of which is fixedly connected to the inner bottom end of the base, a transmission rod fixedly connected to the transmission end of the drive motor, a vertical plate movably sleeved on the outer wall of the transmission rod, the bottom end of the vertical plate fixedly connected to the inner bottom end of the base, and a driving bevel gear fixedly connected to one end of the transmission rod through the vertical plate, the outer wall of the driving bevel gear meshing with the driven bevel gear.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] 1. This utility model, by incorporating a limiting component, facilitates the stable positioning and fixing of the rotary table and the level instrument body. The two cylinders in the limiting component can drive the connecting rod to move the movable support. In conjunction with the linkage of the turntable, the main guide rod, and the secondary guide rod, the three sliders can slide synchronously along the square groove, thereby causing the clamping block to form a closed clamping around the rotary table. At the same time, the soft rubber anti-slip protective pad on the inner side of the clamping block can not only prevent hard damage to the rotary table during clamping, but also enhance the clamping friction, effectively preventing the level instrument body from shifting due to vibration or external force during measurement, significantly improving the stability and accuracy of the measurement operation.

[0022] 2. This utility model, by incorporating a height adjustment component, facilitates convenient and precise adjustment of the level instrument's height to adapt to different engineering measurement scenarios. The drive motor in the height adjustment component can drive the active bevel gear to rotate via a transmission rod. The active bevel gear meshes with the driven bevel gear, driving the screw to rotate stably under the support of the limit column. This causes the threaded sleeve to rise and fall along the screw axis, ultimately adjusting the height of the rotary table and the level instrument. The entire adjustment process requires no manual operation, reducing the labor intensity of operators and ensuring the accuracy of height adjustment through the stable transmission of the motor, significantly improving the ease of use and adaptability of the device.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-5 As shown, this utility model has the following two specific embodiments.

[0031] Example 1

[0032] This utility model is a support device for an engineering surveying level instrument, including a level instrument body 1, a bracket 2 fixedly connected to the bottom end of the level instrument body 1, a rotating platform 3 fixedly connected to the bottom end of the bracket 2, lifting limit rods 4 fixedly connected to the bottom end of the rotating platform 3 near both sides, a base 5 fixedly connected to the bottom end of the two lifting limit rods 4, and universal self-locking wheels 6 fixedly connected to the four corners of the bottom end of the base 5. Three square sliding grooves 201 are opened near the middle of the bracket 2.

[0033] The support device for the engineering surveying level also includes:

[0034] Limiting component 8 is provided at bracket 2 and is used to limit and fix the rotary table 3 under the support of bracket 2;

[0035] The height adjustment component 7 is disposed inside the base 5 and between the bottom of the rotating platform 3, and is used to adjust the height of the rotating platform 3 and the level body 1.

[0036] Limiting component 8 includes:

[0037] Two cylinders 804 are located inside the bracket 2 near the top. Connecting rods 805 are fixedly connected between the two ends of the two cylinders 804. A fixed support 806 is fixedly sleeved in the middle of the left connecting rod 805. The top of the fixed support 806 is fixedly connected to the top of the inner wall of the bracket 2. A movable support 810 is fixedly sleeved in the middle of the right connecting rod 805. A slider 801 is fixedly attached to the top of the movable support 810. A main guide rod 809 is movably sleeved at the bottom of the slider 801 through a movable column. A turntable 808 is movably sleeved at the other end of the main guide rod 809 through a movable column. The top center of the turntable 808 is rotatably connected to the middle of the bracket 2 through a rotating column.

[0038] The secondary guide mechanism is located at the diagonal of the turntable 808, and rotates accordingly as the turntable 808 rotates.

[0039] The secondary guide mechanism includes two secondary guide rods 807. The opposite ends of the two secondary guide rods 807 are movably connected to the diagonal of the turntable 808 via movable columns. The ends of the two secondary guide rods 807 that are far apart from each other are movably connected to sliders 801 via movable columns. The tops of the three sliders 801 are all fixedly connected to clamping blocks 802.

[0040] The outer walls of the three sliders 801 are slidably connected to the square groove 201. The opposite sides of the three clamping blocks 802 are fixedly connected to protective pads 803. The three protective pads 803 are all made of soft rubber anti-slip material. The rotating table 3 is set between the three protective pads 803.

[0041] In this embodiment, as Figure 1-4 As shown, the two cylinders 804 in the limiting assembly 8 can drive the connecting rod 805 to move the movable support 810. With the linkage of the turntable 808, the main guide rod 809 and the secondary guide rod 807, the three sliders 801 can slide synchronously along the square slide groove 201, thereby driving the clamping block 802 to form an encircling clamp on the rotary table 3. At the same time, the soft rubber anti-slip material protective pad 803 on the inner side of the clamping block 802 can not only avoid hard damage to the rotary table 3 during the clamping process, but also enhance the clamping friction.

[0042] Example 2

[0043] The difference from Embodiment 1 is that this embodiment discloses a height adjustment component 7 comprising:

[0044] The bottom end of the limiting post 705 is fixedly connected to the inner bottom end of the base 5. The top end of the limiting post 705 is movably sleeved with a driven bevel gear 706 through a bearing. The middle part of the driven bevel gear 706 is fixedly connected with a screw 707. The outer wall of the screw 707 is movably sleeved with the base 5. The outer wall of the screw 707 is threaded with a threaded sleeve 708. The top end of the threaded sleeve 708 is fixedly connected to the middle part of the bottom end of the rotary table 3.

[0045] The drive mechanism is located on the outer wall of the driven bevel gear 706 and is used to drive the driven bevel gear 706 to rotate the screw 707.

[0046] The drive mechanism includes a drive motor 701. The bottom end of the drive motor 701 is fixedly connected to the inner bottom end of the base 5. A transmission rod 702 is fixedly connected to the transmission end of the drive motor 701. A vertical plate 703 is movably sleeved on the outer wall of the transmission rod 702. The bottom end of the vertical plate 703 is fixedly connected to the inner bottom end of the base 5. One end of the transmission rod 702 passes through the vertical plate 703 and is fixedly connected to a driving bevel gear 704. The outer wall of the driving bevel gear 704 meshes with a driven bevel gear 706.

[0047] In this embodiment, as Figure 1-2 and Figure 5 As shown, the drive motor 701 in the height adjustment assembly 7 can drive the active bevel gear 704 to rotate through the transmission rod 702. The active bevel gear 704 meshes with the driven bevel gear 706 to drive the screw 707 to rotate stably under the support of the limit post 705, thereby causing the threaded sleeve 708 to rise and fall along the screw axis, and finally driving the rotary table 3 and the level body 1 to achieve height adjustment.

[0048] The working principle of this utility model is as follows: The two cylinders 804 in the limiting component 8 can drive the connecting rod 805 to move the movable support 810. With the linkage of the turntable 808, the main guide rod 809 and the auxiliary guide rod 807, the three sliders 801 can slide synchronously along the square slide groove 201, thereby driving the clamping block 802 to form a closed clamping on the rotary table 3. At the same time, the soft rubber anti-slip material protective pad 803 on the inner side of the clamping block 802 avoids hard damage to the rotary table 3 during the clamping process, enhances the clamping friction, and prevents the level body 1 from being displaced due to vibration or external force during the measurement process. The drive motor 701 in the height adjustment component 7 can drive the active bevel gear 704 to rotate through the transmission rod 702. The active bevel gear 704 meshes with the driven bevel gear 706 to drive the screw 707 to rotate stably under the support of the limiting column 705, thereby causing the threaded sleeve 708 to rise and fall along the screw axis, and finally driving the rotary table 3 and the level body 1 to achieve height adjustment.
