By using advanced devices such as total stations, the surveying and mapping device can quickly obtain topographic and geomorphic information, improve the efficiency and accuracy of surveying and mapping, and thus provide reliable data support for the planning, design and construction of engineering projects. In addition, modern surveying and mapping devices also have portability and stability, which are convenient for operation in various environments and ensure the continuity and accuracy of surveying and mapping work.

The utility model discloses a surveying and mapping device for construction project cost, including a surveying pen, a pen cap is arranged at the top of the surveying pen, a threaded shaft is movably connected to the top of the pen cap, and a threaded sleeve is movably sleeved on the top surface of the threaded shaft. By using the cooperation of the surveying rod, the anti-slip sleeve, the pen cap, the fixing block, the threaded sleeve, the scale guide rod, the baffle, the threaded shaft, the limiting sleeve, the upper clamping body, the lower clamping body, the controller, the breathing lamp, the second anti-slip knob, the second scale body, the fixed shaft, the first scale body, the solar power storage board, the GPS positioning module, the sliding sleeve, the limiting groove, the limiting block, the pen core and the threaded shell, the problems that the existing surveying and mapping device for construction project cost usually does not have the function of measuring the diameter and length of an object and usually does not have an automatic positioning function, resulting in possible loss and other situations during its use are solved.

[0004] The above device clamps the object to be measured through the upper clamping body and the lower clamping body, so as to measure the data of the object to be measured. However, when measuring the lowest point of the concave part of the arc surface by the above device, since the corresponding surfaces between the upper clamping body and the lower clamping body are pure planes, it may encounter the situation that it cannot fully contact the fine concave and convex parts of the arc surface, resulting in inaccurate measurement data and affecting the measurement efficiency of the measuring device. In view of this, we provide a surveying and mapping device for construction project cost. Content of the Utility Model

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a surveying and mapping device for construction project cost.

[0006] To achieve the above object, the present utility model provides the following technical solution: A surveying device for construction project cost, including a measuring handle. On both sides of the top surface of the measuring handle, a group of corresponding limiting slide rails are fixedly connected. And at the outer end of the outer wall of the limiting slide rail far from the measuring handle, a top support is fixedly connected. The top support is located at the center of the top of the measuring handle. And the center of the top of the measuring handle is slidably connected with a sliding support through the limiting slide rail. A threaded screw rod is rotatably connected to the center of the top surface of the measuring handle. And the threaded screw rod is simultaneously located at the center of the inner part of the sliding support and the bottom surface center of the top support. An adjustment window is opened on one side of the outer wall of the measuring handle. And at the top end inside the measuring handle, an adjustment knob is simultaneously rotatably connected. A group of corresponding measuring calipers are fixedly connected to the outer walls of the top support and the sliding support respectively.

[0007] As described above, the limiting slide rails are located on both sides inside the sliding support. And the sliding support and the measuring calipers are both slidably connected to the top of the measuring handle through the limiting slide rails.

[0008] As described above, one end of the outer wall of the limiting slide rail penetrates through one side of the top surface of the sliding support. And the center of the outer wall of the limiting slide rail is slidably connected to one side inside the sliding support.

[0009] As described above, a plurality of groups of scale lines are opened on both sides of the outer wall of the limiting slide rail. And the scale lines correspond to the outer wall of the top end of the sliding support.

[0010] As described above, one side of the outer wall of the adjustment knob penetrates through one side inside the adjustment window. And one side of the outer wall of the adjustment knob is rotatably connected to one side inside the adjustment window.

[0011] As described above, the bottom of the outer wall of the threaded screw rod penetrates through the center of the top surface of the sliding support. And the bottom of the outer wall of the threaded screw rod is rotationally connected to the center of the inside of the sliding support through a thread.

And the bottom outer wall of the threaded screw rod penetrates through the top end inside the measuring handle and is fixedly connected to the center of the top surface of the adjustment knob. The measuring calipers are respectively fixedly connected to one side of the outer walls of the top support and the sliding support. And the partial cross-section of the measuring caliper is mainly a triangular structure.

[0013] Compared with the prior art, this surveying device for construction project cost has the following beneficial effects:

[0014] First, the present utility model sets the limiting slide rail between the top support and the measuring handle. And through the penetration of the limiting slide rail and one side inside the sliding support, the movement track of the sliding support is restricted. When the sliding support drives the measuring caliper on one side of its outer wall to move, it can only move vertically along the outer wall of the limiting slide rail, ensuring the smoothness and stability of the movement of the measuring caliper during the measurement process.

[0015] II. By setting the cross-section of the measuring caliper of the present utility model as a triangle, the measuring caliper can better fit the surface of the object to be measured. Subsequently, after the measuring caliper on one side of the outer wall of the top support is abutted against the surface of the object to be measured, the adjusting knob is rotated to drive the threaded lead screw to rotate at the center of the top surface of the measuring handle. At the same time, under the combined action of the threaded lead screw and the limit slide rail, the sliding support and the measuring caliper on one side of its outer wall are pushed to move along the limit slide rail towards the outer wall of the object to be measured. When the measuring calipers are all abutted against the surface of the object to be measured, observe which scale line on the outer wall of the top of the sliding support is aligned with the scale, and record the relevant data. Furthermore, by using the measuring caliper with a triangular cross-section, the device can effectively and accurately measure the object to be measured with an irregular shape or an arc-shaped outer wall.

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-4As shown in the figure, the present utility model provides a technical solution: a surveying and mapping device for construction project cost, including a measuring handle 1. On both sides of the top surface of the measuring handle 1, a group of corresponding limiting slide rails 2 are fixedly connected. One end of the outer wall of the limiting slide rail 2 far from the measuring handle 1 is fixedly connected with a top support 201. The top support 201 is located at the center of the top of the measuring handle 1. The center of the top of the measuring handle 1 is slidably connected with a sliding support 202 through the limiting slide rail 2. The center of the top surface of the measuring handle 1 is rotatably connected with a threaded screw rod 3. The threaded screw rod 3 is located at the center of the inside of the sliding support 202 and the center of the bottom surface of the top support 201 at the same time. On one side of the outer wall of the measuring handle 1, an adjustment window 301 is opened. At the same time, the top end inside the measuring handle 1 is rotatably connected with an adjustment knob 302. On the outer walls of the top support 201 and the sliding support 202, a group of corresponding measuring calipers 303 are fixedly connected.

[0024] By arranging the limiting slide rail 2 between the top support 201 and the measuring handle 1 and passing through one side inside the sliding support 202 through the limiting slide rail 2, the movement track of the sliding support 202 is restricted. By setting the cross-section of the measuring caliper 303 to be triangular, the measuring caliper 303 can better fit the surface of the object to be measured. Then, after the measuring caliper 303 on one side of the outer wall of the top support 201 abuts against the surface of the object to be measured, rotate the adjustment knob 302 to drive the threaded screw rod 3 to rotate at the center of the top surface of the measuring handle 1. At the same time, under the combined action of the threaded screw rod 3 and the limiting slide rail 2, the sliding support 202 and the measuring caliper 303 on one side of its outer wall are pushed to move along the limiting slide rail 2 towards the outer wall of the object to be measured. When the measuring calipers 303 both abut against the surface of the object to be measured, observe which scale line 203 on the outer wall of the top of the sliding support 202 is aligned with the scale, and record the relevant data. Furthermore, by adopting the measuring caliper 303 with a triangular cross-section, the device can effectively and accurately measure the object to be measured with an irregular shape or an arc-shaped outer wall. While improving the degree of fit between the measuring tool and the surface of the object to be measured, it also enhances the stability and accuracy during the measurement process.

[0025] As Figure 1 、 Figure 2 and Figure 4 shown in the figure, the limiting slide rail 2 is located on both sides inside the sliding support 202. The sliding support 202 and the measuring caliper 303 are both slidably connected to the top of the measuring handle 1 through the limiting slide rail 2. One end of the outer wall of the limiting slide rail 2 penetrates through one side of the top surface of the sliding support 202, and the center of the outer wall of the limiting slide rail 2 is slidably connected to one side inside the sliding support 202. When placing the limiting slide rail 2 on both sides of the top surface of the measuring handle 1, the outer wall of the limiting slide rail 2 penetrates through one side inside the sliding support 202, so that the outer wall of the limiting slide rail 2 fits with the inner wall of the sliding support 202 to restrict the movement track of the sliding support 202. When the sliding support 202 moves, it can only move vertically along the outer wall of the limiting slide rail 2.

[0026] On both sides of the outer wall of the limit slide rail 2, multiple groups of scale lines 203 are provided, and the scale lines 203 correspond to the outer wall of the top of the sliding support 202. By providing multiple groups of scale lines 203 on the outer wall of the limit slide rail 2, when the sliding support 202 moves on the outer wall of the limit slide rail 2, it can be aligned with the scale on a certain scale line 203 by passing through the outer wall of the top of the sliding support 202, so as to accurately determine the detailed spacing value between the sliding support 202 and the top support 201.

[0027] As Figures 1-4 shown, one side of the outer wall of the adjustment knob 302 penetrates through one side of the interior of the adjustment window 301, and one side of the outer wall of the adjustment knob 302 is rotatably connected to one side of the interior of the adjustment window 301. By the penetration of the adjustment knob 302 through one side of the interior of the adjustment window 301, the operator can operate the adjustment knob 302 through the adjustment window 301 and rotate the adjustment knob 302 through the adjustment window 301.

[0028] The bottom of the outer wall of the threaded lead screw 3 penetrates through the center of the top surface of the sliding support 202, and the bottom of the outer wall of the threaded lead screw 3 is rotatably connected to the center of the interior of the sliding support 202 through a thread. The outer wall of the threaded lead screw 3 penetrates through the center of the interior of the sliding support 202 and is rotatably connected to the center of the interior of the sliding support 202 through the thread on its outer wall. As the threaded lead screw 3 rotates, the threaded lead screw 3 cooperates with the limit slide rail 2 to drive the sliding support 202 and one of the measuring calipers 303 to move vertically along the outer wall of the limit slide rail 2.

[0029] The bottom of the outer wall of the threaded lead screw 3 is connected through the center of the top surface of the measuring handle 1, and the bottom of the outer wall of the threaded lead screw 3 penetrates through the top end of the interior of the measuring handle 1 and is fixedly connected to the center of the top surface of the adjustment knob 302. By the penetration of the bottom of the outer wall of the threaded lead screw 3 through the top end of the interior of the measuring handle 1 and the fixation of the center of its bottom surface to the center of the top surface of the adjustment knob 302, when the operator operates the adjustment knob 302 through the adjustment window 301, the threaded lead screw 3 can be synchronously driven to rotate at the center of the top surface of the measuring handle 1.

[0030] The measuring calipers 303 are respectively fixedly connected to one side of the outer walls of the top support 201 and the sliding support 202, and the partial cross-section of the measuring calipers 303 is mainly a triangular structure. By setting the cross-section of the measuring calipers 303 as a triangle, when the device measures the fine concave and convex parts of the arc surface through the measuring calipers 303, it can better fit the surface of the object to be measured and help reduce the possible gaps during the measurement process, thereby improving the measurement accuracy.

[0031] Working principle: While placing the limit slide rail 2 on both sides of the top surface of the measuring handle 1, penetrate one side inside the sliding support 202 through the outer wall of the limit slide rail 2, so that the limit slide rail 2 fits against the inner wall of the sliding support 202 through its outer wall, restricting the movement trajectory of the sliding support 202. When the sliding support 202 moves, it can only move vertically along the outer wall of the limit slide rail 2. By opening multiple groups of scale lines 203 on the outer wall of the limit slide rail 2, when the sliding support 202 moves on the outer wall of the limit slide rail 2, it can be aligned with the scale on a certain scale line 203 by penetrating the top outer wall of the sliding support 202, so as to accurately determine the detailed spacing value between the sliding support 202 and the top support 201. The adjusting knob 302 penetrates through one side inside the adjusting window 301, enabling the operator to operate the adjusting knob 302 through the adjusting window 301. Rotate the adjusting knob 302 through the adjusting window 301, penetrate the outer wall of the threaded lead screw 3 through the center inside the sliding support 202, and connect it to the center inside the sliding support 202 through the thread on its outer wall. As the threaded lead screw 3 rotates, the threaded lead screw 3 cooperates with the limit slide rail 2 to drive the sliding support 202 and one of the measuring calipers 303 to move vertically along the outer wall of the limit slide rail 2. The bottom outer wall of the threaded lead screw 3 penetrates through the top inside the measuring handle 1, and the center of its bottom surface is fixedly connected to the center of the top surface of the adjusting knob 302, so that when the operator operates the adjusting knob 302 through the adjusting window 301, it can synchronously drive the threaded lead screw 3 to rotate at the center of the top surface of the measuring handle 1. By setting the cross-section of the measuring caliper 303 to be triangular, when the device measures the fine concave and convex parts of the arc surface through the measuring caliper 303, it can better fit the surface of the object to be measured, and helps to reduce the possible gaps during the measurement process, thereby improving the measurement accuracy.
