Description

Technical Field

[0001] This utility model relates to the field of architectural construction surveying technology, and in particular to a support frame for an architectural construction surveying instrument. Background Technology

[0002] Currently, surveying instruments are required for building surveying during construction. These instruments are typically used with support frames to provide stable support. In practical use, surveying instruments need to maintain a certain level of horizontality to ensure the accuracy of the surveyed data. Existing surveying instrument support frames (such as the support frame for a building construction surveying device disclosed in application number 202321317777.1) can confirm the horizontality of the placement plate by observing the positional relationship between the plumb block at the bottom of the plumb line and the detection tube, thus confirming the horizontality of the surveying instrument. However, they cannot adjust the horizontality of the placement plate, and therefore cannot adjust the horizontality of the surveying instrument. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a support frame for a construction surveying instrument, thereby solving the technical problem that the existing support frame for the surveying instrument cannot adjust the levelness of the surveying instrument.

[0004] To achieve the above technical objectives, the present invention provides a support frame for a construction surveying instrument, comprising:

[0005] The supporting mechanism on which the surveying instrument is placed;

[0006] Multiple support mechanisms, each having a fixed end and a telescopic end, wherein each fixed end is rotatably connected to the bearing mechanism to adjust the tilt angle of the fixed end.

[0007] Furthermore, the supporting mechanism includes a supporting plate and multiple mounting seats. The supporting plate is used to place the surveying instrument. The multiple mounting seats are distributed in a circle and are all fixedly connected to the supporting plate. Each fixed end is rotatably connected to each mounting seat in a one-to-one correspondence.

[0008] Furthermore, each of the support mechanisms includes a fixed support rod, a movable support rod, and a fastening assembly. The upper end of the fixed support rod forms the fixed end and is rotatably connected to the mounting base to adjust the tilt angle of the fixed support rod. The movable support rod is slidably connected to the fixed support rod and can move along the length direction of the fixed support rod to adjust the extension length of the movable support rod. The fastening assembly is detachably and fixedly connected to the fixed support rod and the movable support rod.

[0009] Furthermore, the fixed support rod has a receiving cavity extending along its length, the movable support rod is slidably disposed in the receiving cavity, and the lower end of the movable support rod extends out of the fixed support rod.

[0010] Furthermore, the fastening assembly includes a fastener and an elastic element. The fastener is rotatably connected to the fixed support rod, and the elastic element connects the fastener and the fixed support rod so that the fastener abuts against the side wall of the movable support rod.

[0011] Furthermore, the fixed support rod has a slot communicating with the accommodating cavity. The fastener is rotatably disposed at the slot. The fastener includes a rotating shaft, a roller, and a gripping rod. The rotating shaft is horizontally disposed and rotatably connected to the fixed support rod. The roller is eccentrically fixedly sleeved on the rotating shaft. One end of the gripping rod is fixedly connected to the roller, and the other end of the gripping rod extends out of the fixed support rod. The elastic element connects the roller and the fixed support rod so that the arc-shaped wall of the roller abuts against the side wall of the movable support rod.

[0012] Furthermore, the sidewalls of the movable support rod and the arc-shaped wall of the abutment roller are both rough surfaces.

[0013] Furthermore, the elastic element includes two torsion springs, which are respectively disposed on both sides of the abutment roller and both are sleeved on the rotating shaft.

[0014] Furthermore, the building construction surveying instrument support frame also includes a connecting mechanism, which includes multiple connecting ropes of equal length, each of which is disposed between adjacent fixed support rods, and the connecting ropes are fixedly connected to two adjacent fixed support rods.

[0015] Furthermore, a circular water tank is provided on the support plate, and a circular reference line is provided on the side wall of the water tank. The water tank is used to hold a solution. When the support plate is in a horizontal state, the liquid level of the solution in the water tank coincides with the reference line.

[0016] Compared with the prior art, the beneficial effects of this utility model include: when setting up this support frame, each support mechanism is opened at the same preset angle. When each support mechanism has the same length, if the ground is flat, the bearing mechanism can be kept in a horizontal state after the bottom of each support mechanism contacts the ground. The surveying instrument is placed on the bearing mechanism. If the ground is uneven, the level of the bearing mechanism needs to be adjusted. When the level of the bearing mechanism needs to be adjusted, the corresponding support mechanism is operated according to the adjustment requirements, so that the support mechanism is extended or shortened. When the support mechanism is extended or shortened, the corresponding side of the bearing mechanism will move up or down, thereby adjusting the level of the bearing mechanism, and thus adjusting the level of the surveying instrument.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] This utility model provides a support frame for a construction surveying instrument, the structure of which is as follows: Figure 1 - Figure 2 As shown, it includes a bearing mechanism 100 and multiple support mechanisms 200200. The bearing mechanism 100 is used to place a surveying instrument. Each support mechanism 200200 has a fixed end and a telescopic end. Each fixed end is rotatably connected to the bearing mechanism 100 to adjust the tilt angle of the fixed end.

[0022] When setting up this support frame, each of the support mechanisms 200200 is opened to the same preset tilt angle. If the ground is flat, and the bottom of each support mechanism 200200 contacts the ground, the bearing mechanism 100 will remain horizontal. The surveying instrument is then placed on the bearing mechanism 100. If the ground is uneven, the horizontality of the bearing mechanism 100 needs to be adjusted. When adjusting the horizontality of the bearing mechanism 100, the corresponding support mechanism 200200 is operated according to the adjustment requirements, causing it to extend or shorten. When the support mechanism 200200 extends or shortens, the corresponding side of the bearing mechanism 100 will move upward or downward, thus adjusting the horizontality of the bearing mechanism 100 and consequently, adjusting the horizontality of the surveying instrument.

[0023] As a preferred embodiment, please refer to Figure 1 The supporting mechanism 100 includes a supporting plate 110 and a plurality of mounting seats 120. The supporting plate 110 is used to place the surveying instrument. The plurality of mounting seats 120 are circumferentially distributed and are all fixedly connected to the supporting plate 110. Each fixed end is rotatably connected to each mounting seat 120 in a one-to-one correspondence. The supporting plate 110 realizes the supporting function of the surveying instrument, and the mounting seats 120 realize the rotatable connection with the fixed end.

[0024] As a preferred embodiment, please refer to Figure 1 and Figure 2 Each of the support mechanisms 200 includes a fixed support rod 210, a movable support rod 220, and a fastening assembly 230. The upper end of the fixed support rod 210 forms the fixed end and is rotatably connected to the mounting base 120 to adjust the tilt angle of the fixed support rod 210. The movable support rod 220 is slidably connected to the fixed support rod 210 and can move along the length direction of the fixed support rod 210 to adjust the extension length of the movable support rod 220. The fastening assembly 230 is detachably and fixedly connected to the fixed support rod 210 and the movable support rod 220. When each of the fixed support rods 210 is opened to the same preset tilt angle and each of the movable support rods 220 extends to the same length, if the ground is flat, the bearing plate 110 can be kept horizontal after the bottom of each of the movable support rods 220 contacts the ground. The surveying instrument is placed on the bearing plate 110. If the ground is uneven, The level of the support plate 110 needs to be adjusted. When the level of the support plate 110 needs to be adjusted, the corresponding fastening component 230 is operated according to the adjustment requirements, so that the movable support rod 220 is in the unlocked state. The movable support rod 220 is moved along the length direction of the fixed support rod 210, and the extension length of the movable support rod 220 is adjusted. This allows the overall length of the fixed support rod 210 and the movable support rod 220 to be adjusted. When the overall length of the fixed support rod 210 and the movable support rod 220 increases or decreases, the corresponding side of the support plate 110 will move up or down, thereby adjusting the level of the support plate 110 and thus adjusting the level of the surveying instrument.

[0025] As a preferred embodiment, please refer to Figure 1 The fixed support rod 210 has a receiving cavity 211 extending along its length direction. The movable support rod 220 is slidably disposed in the receiving cavity 211, and the lower end of the movable support rod 220 extends out of the fixed support rod 210. The receiving cavity 211 can accommodate the movable support rod 220 and guide the movement of the movable support rod 220.

[0026] As a preferred embodiment, please refer to Figure 2 The fastening assembly 230 includes a fastener 231 and an elastic element 232. The fastener 231 is rotatably connected to the fixed support rod 210. The elastic element 232 connects the fastener 231 and the fixed support rod 210, so that the fastener 231 abuts against the side wall of the movable support rod 220. Rotating the fastener 231 can loosen the side wall of the movable support rod 220. At this time, the elastic element 232 undergoes elastic deformation and accumulates elastic potential energy. The movable support rod 220 is in an unlocked state. The movable support rod 220 is moved along the length direction of the fixed support rod 210 to adjust the extension length of the movable support rod 220. When the extension length of the movable support rod 220 is adjusted to a preset value, the fastener 231 is released, and the elastic element 232 releases its elastic potential energy, so that the fastener 231 abuts against the side wall of the movable support rod 220 again, thereby locking the position of the movable support rod 220.

[0027] As a preferred embodiment, please refer to Figure 2 The fixed support rod 210 has a slot 212 communicating with the receiving cavity 211. The fastener 231 is rotatably disposed at the slot 212, so that the fastener 231 can abut against the side wall of the movable support rod 220. The fastener 231 includes a rotating shaft 2311, a roller 2312, and a gripping rod 2313. The rotating shaft 2311 is horizontally disposed and rotatably connected to the fixed support rod 210. The roller 2312 is eccentrically fixedly sleeved on the rotating shaft 2311. One end of the gripping rod 2313 is fixedly connected to the roller 2312, and the other end of the gripping rod 2313 extends out of the fixed support rod 210. The elastic element 232 connects the roller 2312 and the fixed support rod 210 so that the arc-shaped wall of the roller 2312 abuts against the side wall of the movable support rod 220. The gripping rod 2313 is held by hand. Rotating the grip 2313 upwards or downwards causes the abutment roller 2312 to rotate in the forward or reverse direction. Since the abutment roller 2312 is eccentrically connected to the rotating shaft 2311, when the abutment roller 2312 rotates in the forward or reverse direction, the abutment roller 2312 releases the side wall of the movable support rod 220. At this time, the elastic element 232 undergoes elastic deformation and accumulates elastic potential energy, and the movable support rod 220 is in the unlocked state. Moving the movable support rod 220 along the length direction of the fixed support rod 210 adjusts the extension length of the movable support rod 220. When the extension length of the movable support rod 220 is adjusted to a preset value, the grip 2313 is released, and the elastic element 232 releases elastic potential energy, causing the abutment roller 2312 to press against the side wall of the movable support rod 220 again, thereby locking the position of the movable support rod 220.

[0028] In a preferred embodiment, the sidewalls of the movable support rod 220 and the arc-shaped wall of the abutment roller 2312 are both rough surfaces, which can improve the friction between the abutment roller 2312 and the movable support rod 220.

[0029] In a preferred embodiment, the abutting roller 2312 has a deformable structure, which can increase the contact area between the abutting roller 2312 and the movable support rod 220, and further improve the friction between the abutting roller 2312 and the movable support rod 220.

[0030] As a preferred embodiment, please refer to Figure 2 The elastic element 232 includes two torsion springs 2321, which are respectively disposed on both sides of the abutment roller 2312 and both sleeved on the rotating shaft 2311. When the abutment roller 2312 rotates in the forward or reverse direction, the abutment roller 2312 releases the side wall of the movable support rod 220. At this time, the torsion spring 2321 undergoes tensile elastic deformation and accumulates tensile elastic potential energy, and the movable support rod 220 is in the unlocked state.

[0031] As a preferred embodiment, please refer to Figure 1 The building construction surveying instrument support frame also includes a connecting mechanism 300, which includes multiple connecting ropes 310, each of which is of equal length and is respectively disposed between adjacent fixed support rods 210. The connecting ropes 310 are fixedly connected to two adjacent fixed support rods 210. When the support frame is erected, each fixed support rod 210 is opened to its maximum tilt angle. At this time, each connecting rope 310 is in a taut state. When each movable support rod 220 extends to the same length, if the ground is flat, the bearing plate 110 can be kept in a horizontal state after the bottom of each movable support rod 220 contacts the ground.

[0032] As a preferred embodiment, please refer to Figure 1 A circular water tank 111 is provided on the support plate 110. A circular reference line is provided on the side wall of the water tank 111. The water tank 111 is used to hold a solution. When the support plate 110 is in a horizontal state, the liquid level of the solution in the water tank 111 coincides with the reference line. The levelness of the support plate 110 can be confirmed by observing the angle between the liquid level of the solution in the water tank 111 and the reference line, which facilitates the adjustment of the levelness of the support plate 110.

[0033] To better understand this utility model, the following is combined with... Figure 1 - Figure 2 The working principle of the technical solution of this utility model will be described in detail below:

[0034] When erecting this support frame, each of the fixed support rods 210 is opened to its maximum tilt angle. At this time, each of the connecting ropes 310 is in a taut state. With each of the movable support rods 220 extended to the same length, if the ground is flat, the bearing plate 110 can be kept horizontal after the bottom of each of the movable support rods 220 contacts the ground. The surveying instrument is placed on the bearing plate 110. If the ground is uneven, the levelness of the bearing plate 110 needs to be adjusted. When adjustment is required... When adjusting the level of the bearing plate 110, operate the corresponding fastening assembly 230 according to the adjustment requirements. Hold the handle 2313 and rotate it upwards or downwards, thereby driving the abutment roller 2312 to rotate in the forward or reverse direction. Since the abutment roller 2312 is eccentrically connected to the rotating shaft 2311, when the abutment roller 2312 rotates in the forward or reverse direction, the abutment roller 2312 releases the side wall of the movable support rod 220. At this time, the elastic element 232 undergoes elastic deformation. And accumulate elastic potential energy. The movable support rod 220 is in the unlocked state. The movable support rod 220 is moved along the length direction of the fixed support rod 210 to adjust the extension length of the movable support rod 220. When the extension length of the movable support rod 220 is adjusted to a preset value, the grip rod 2313 is released. The elastic element 232 releases elastic potential energy, so that the abutment roller 2312 presses against the side wall of the movable support rod 220 again to lock the position of the movable support rod 220. The movable support rod 220 is moved along the length direction of the fixed support rod 210 to adjust the extension length of the movable support rod 220. Thus, the overall length of the fixed support rod 210 and the movable support rod 220 can be adjusted. When the overall length of the fixed support rod 210 and the movable support rod 220 increases or decreases, the corresponding side of the bearing plate 110 will move up or down to adjust the level of the bearing plate 110, thereby enabling the adjustment of the level of the surveying instrument.

[0035] The building construction surveying instrument support frame provided by this utility model has the following beneficial effects:

[0036] (1) When erecting this support frame, each of the fixed support rods 210 is opened to the maximum tilt angle. At this time, each of the connecting ropes 310 is in a straight state. When each of the movable support rods 220 extends to the same length, if the ground is flat, after the bottom of each of the movable support rods 220 contacts the ground, the bearing plate 110 can be kept in a horizontal state.

[0037] (2) When the support plate 110 is in a horizontal state, the liquid level of the solution in the water tank 111 coincides with the baseline. By observing the angle between the liquid level of the solution in the water tank 111 and the baseline, the levelness of the support plate 110 can be confirmed, which makes it easier to adjust the levelness of the support plate 110.

[0038] (3) Adjust the extension length of the movable support rod 220, thereby adjusting the overall length of the fixed support rod 210 and the movable support rod 220. When the overall length of the fixed support rod 210 and the movable support rod 220 increases or decreases, the side of the bearing plate 110 will move up or down, thereby adjusting the level of the bearing plate 110 and thus adjusting the level of the surveying instrument.

[0039] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
