Description

Technical Field

[0001] This utility model belongs to the field of instrument support technology, and in particular relates to a support frame for a vertical testing device used in building engineering. Background Technology

[0002] In the construction and acceptance process of building engineering, vertical testing devices are instruments used to measure whether structures such as walls, columns, and poles are perpendicular to the horizontal plane. Common types include plumb lines, laser line projectors, and total stations. Their core function is to provide a vertical reference through physical or electronic principles to determine the verticality deviation of the target structure. Support frames for these vertical testing devices provide auxiliary structures for installation, height adjustment, and stable support. By bearing the load and maintaining their position, they ensure the accuracy of the baseline or measurement points during the testing process.

[0003] However, most of the support frames in the existing technology are simple telescopic brackets or fixed brackets, which generally lack a dedicated horizontal calibration function: when the ground of the construction site is uneven (such as foundation pits or rough ground) or the bracket placement angle is deviated, the tilt of the support frame itself will directly cause the baseline of the detection device to shift, which in turn will cause errors in the verticality measurement results (for example, the laser projection instrument emits a non-vertical laser line due to the tilt of the bracket). Utility Model Content

[0004] The purpose of this utility model is to provide a support frame for a vertical testing device in building engineering. By setting a horizontal calibration adjustment component at the bottom of the telescopic support rod assembly and cooperating with the cylindrical spirit level on the top of the support platform to achieve precise horizontal calibration, the existing support frame is prone to tilting when used on uneven ground due to the lack of a dedicated horizontal calibration function, which in turn causes the baseline of the testing device to deviate and the testing results to be incorrect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a support frame for a vertical detection device used in building engineering, including a support platform. Three telescopic support rod groups are rotatably installed in a circular array on the periphery of the support platform, and a horizontal calibration adjustment component is fixedly installed at the bottom of the telescopic support rod groups. The horizontal calibration and adjustment assembly includes a connecting seat fixedly connected to the bottom of the telescopic support rod assembly. A through hole is provided on one side of the connecting seat, and an adjusting sleeve is rotatably fitted on the other side of the connecting seat. A screw is threadedly connected to the inner circumferential side of the adjusting sleeve. The screw passes through the adjusting sleeve and the through hole in sequence, and a triangular support foot is fixedly connected to the end of the screw away from the connecting seat.

[0006] The present invention is further configured such that two symmetrical limiting keys are fixedly connected to the inner circumferential side of the connecting seat, and two symmetrical keyways are opened on the circumferential side of the screw, and the two limiting keys slide in cooperation with the two keyways respectively.

[0007] The present invention is further provided that the outer peripheral side of the adjusting sleeve is provided with friction texture.

[0008] The present invention is further configured such that an adapter is rotatably mounted on the top of the support platform, and an installation groove is provided on one side of the adapter, into which a cylindrical horizontal bubble is embedded.

[0009] The present invention is further configured such that a connecting hole is provided through the inside of the adapter, a connecting shaft is rotatably fitted in the connecting hole, and a U-shaped mounting base is fixedly connected to both ends of the connecting shaft.

[0010] The present invention is further configured such that a threaded hole is provided on the other side of the adapter, the threaded hole is connected to the connecting hole, an adjusting pressure rod is threadedly connected inside the threaded hole, and a locking shaft arc-shaped stop is provided at one end of the adjusting pressure rod, the arc surface profile of the locking shaft arc-shaped stop is adapted to fit the curved surface features of the side surface of the connecting shaft.

[0011] This utility model has the following beneficial effects: This invention achieves precise leveling by using a horizontal calibration and adjustment component at the bottom of the telescopic support rod assembly in conjunction with a cylindrical level bubble at the top of the support platform. This compensates for tilting caused by uneven ground or initial height differences, ensuring stable testing benchmarks and improving result accuracy. Furthermore, the device employs a conventional mechanical structure, eliminating the need for complex electronic components and resulting in low manufacturing costs.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0016] 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. Specific Implementation

[0017] Please see Figure 1-5 This utility model is a support frame for a vertical detection device used in building engineering. It includes a support platform 1, and three telescopic support rod groups 2 are rotatably installed in a circular array on the side of the support platform 1. A horizontal calibration and adjustment component 3 is fixedly installed at the bottom of the telescopic support rod group 2. By adopting a three-point support structure, the stability of the overall support is ensured by utilizing the principle of triangle stability. The telescopic support rod group 2 with a buckle structure can initially adjust the height of the vertical detection device to adapt to different sites.

[0018] Specifically, the horizontal calibration adjustment assembly 3 includes a connecting seat 4 fixedly connected to the bottom of the telescopic support rod assembly 2. A through hole 5 is provided on one side of the connecting seat 4, and an adjusting sleeve 6 is rotatably fitted on the other side of the connecting seat 4. A screw 7 is threadedly connected to the inner circumferential side of the adjusting sleeve 6. The screw 7 passes through the adjusting sleeve 6 and the through hole 5 in sequence. A triangular support foot 8 is fixedly connected to the end of the screw 7 away from the connecting seat 4. Two symmetrical limit keys 9 are fixedly connected to the inner circumferential side of the connecting seat 4. Two symmetrical keyways 10 are provided on the circumferential side of the screw 7, and the two limit keys 9 slide with the two keyways 10 respectively. The rotational motion is converted into the axial linear motion of the screw 7 by adjusting the threaded engagement between the adjusting sleeve 6 and the screw 7 (when the adjusting sleeve 6 is rotated, the screw 7 moves along the axial direction); the sliding engagement between the limiting key 9 and the keyway 10 restricts the screw 7 to rotate synchronously with the adjusting sleeve 6, ensuring that the screw 7 only moves axially. Since the triangular support foot 8 is in direct contact with the ground, the distance and height difference between the connecting seat 4 and the triangular support foot 8 are adjusted by driving the screw 7 to move relative to the connecting seat 4, so as to compensate for the tilt of the bearing platform 1 caused by uneven ground or the initial height difference of the support legs. Friction grooves 11 are provided on the outer circumference of the adjusting sleeve 6. The friction grooves 11 are used to increase the friction between the hand and the adjusting sleeve 6, so that the operator can hold and rotate the sleeve stably in the construction environment where he is wearing gloves or his hands are covered with dust, and avoid slippage that affects the adjustment accuracy and efficiency.

[0019] Furthermore, an adapter 12 is rotatably mounted on the top of the support platform 1. An installation groove 13 is provided on one side of the adapter 12, and a cylindrical level bubble 14 is embedded in the installation groove 13. The adapter 12 can rotate around the support platform 1 to realize flexible switching of the detection direction. The cylindrical level bubble 14 serves as a horizontal reference component, and the position change of the bubble inside it intuitively reflects the horizontal state of the support platform 1 (the bubble is horizontal when it is in the center), providing a visual basis for horizontal calibration. The adapter 12 has a through-hole 15 inside, and a connecting shaft 16 is rotatably fitted inside the connecting hole 15. Both ends of the connecting shaft 16 are fixedly connected to a U-shaped mounting base 17. The rotatable fit between the connecting shaft 16 and the connecting hole 15 allows the U-shaped mounting base 17 to rotate around the connecting shaft 16, thereby realizing the angle adjustment of the vertical detection device (such as pitch angle adjustment). The U-shaped mounting base 17 provides a stable mounting structure for the detection device, ensuring that the device and the mounting base move synchronously when adjusting the angle. The other side of the adapter 12 has a threaded hole 18, which communicates with the connecting hole 15. An adjusting rod 19 is threadedly connected inside the threaded hole 18. One end of the adjusting rod 19 has a locking shaft arc-shaped stop 20. The arc-shaped profile of the locking shaft arc-shaped stop 20 is adapted to fit the curved surface features of the side of the connecting shaft 16. The adjusting rod 19 and the threaded hole 18 are threaded together to achieve axial movement (the rod moves forward and backward along the threaded hole 18 when it is rotated). The locking shaft arc-shaped stop 20 is adapted to the arc surface of the connecting shaft 16. When moving forward, the connecting shaft 16 is locked by surface contact (fixing the angle of the U-shaped mounting seat 17). When moving backward, the connecting shaft 16 is released to allow the angle of the U-shaped mounting seat 17 to be adjusted. The combination of "threaded transmission + arc-shaped clamping" achieves rapid fixing and release of the angle.

[0020] The operation process of this embodiment is as follows: First, unfold the three telescopic support rod groups 2 with buckle structures, place the support frame on the testing site, and initially stretch / shrink the length of the support rods through the buckle adjustment function of the telescopic support rod groups 2 to make the vertical testing device roughly adapt to the testing height requirements. Then, observe the cylindrical horizontal bubble 14 in the mounting groove 13 at the top of the bearing platform 1. Determine the tilt state of the bearing platform 1 based on the direction of bubble offset. If the bubble is biased in a certain direction, it means that the height of the support foot corresponding to that direction is too low. At this time, rotate the adjusting sleeve 6 corresponding to that support foot. Under the sliding fit restriction of the limit key 9 and the keyway 10, the rotational motion of the adjusting sleeve 6 is converted into the axial linear motion of the screw 7. Rotating the adjusting sleeve 6 clockwise can cause the screw 7 to drive the triangular support foot 8 to move away from the connecting seat 4 to raise the support foot. Rotating it counterclockwise will cause the triangular support foot 8 to move closer to the connecting seat 4. The support 4 is moved to lower the feet. The height of the three feet is adjusted until the bubble in the cylindrical level bubble 14 is centered, thus completing the horizontal calibration of the support platform 1. If it is necessary to adjust the angle of the U-shaped mounting base 17 and the vertical detection device fixed on it, the adjusting rod 19 can be rotated to move the adjusting rod 19 backward along the threaded hole 18. The locking shaft arc stop 20 is separated from the connecting shaft 16. At this time, the connecting shaft 16 can rotate in the connecting hole 15, thereby driving the U-shaped mounting base 17 to adjust to the required angle. After the angle is determined, the adjusting rod 19 is rotated in the opposite direction to move it forward along the threaded hole 18. The locking shaft arc stop 20 fits tightly against the circumferential side of the connecting shaft 16, thus locking the connecting shaft 16 and fixing the angle of the U-shaped mounting base 17 and the vertical detection device. At the same time, the detection direction can be adjusted by rotating the adapter 12, thus completing the preparation work before detection.
