Description

Technical Field

[0001] This utility model belongs to the field of engineering cost surveying technology, and specifically relates to a surveying equipment for construction engineering cost. Background Technology

[0002] In construction cost surveying, the exterior walls, as a crucial component of the building structure, are directly affected by the dimensional accuracy of their construction process, which is crucial for calculating material usage and controlling construction quality. Whether it's the width of mortar joints during the masonry stage, the dimensions of splicing joints in precast exterior wall panels, the gap between the exterior wall finish and the base layer, or the installation gaps of suspended exterior wall components, all require data acquisition through measurement.

[0003] In actual exterior wall measurement operations, especially for high-altitude suspended areas or concealed gaps, existing measurement methods face significant operational difficulties. Suspended areas of the exterior wall lack stable support points, requiring operators to hold measuring tapes or calipers close to the measurement area. The tools are prone to losing their positioning reference due to hand shaking. On the other hand, the measuring components of traditional tools lack precise guiding and transmission mechanisms. When contacting irregular surfaces of the exterior wall or penetrating narrow gaps, the measuring tape is prone to tilting or shifting, resulting in deviations between the measured data and the actual dimensions. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a surveying device for construction project cost estimation.

[0005] To achieve the above objectives, this utility model provides a surveying and mapping device for construction project cost estimation, including a support block. A guide groove is provided on one side of the support block, and a guide strip is slidably connected in the guide groove. A measuring ruler is adhered to the side of the guide strip away from the guide groove. An observation strip is fixedly connected to one side of the support block corresponding to the measuring ruler. A support rod is fixedly connected to the lower end of the support block, and a top plate is fixedly connected to one side of the support rod. A suspended surveying and mapping component is provided on the support block.

[0006] In the above technical solution, the suspended mapping component further includes a support plate fixedly installed on the upper end of the support block. The support plate is rotatably connected to two first rotating shafts on the side near the support block. A first extrusion wheel is fixedly connected to the outer wall of the first rotating shaft, and a first pulley is fixedly installed on the upper end of one of the first rotating shafts.

[0007] In the above technical solution, a second rotating shaft is rotatably connected to the side of the support plate away from the first rotating shaft, and the lower end of the second rotating shaft passes through the support plate, while a second pulley is fixedly installed on the upper end of the second rotating shaft.

[0008] In the above technical solution, the outer walls of the first pulley and the second pulley are jointly fitted with a synchronous belt, and the second shaft is fixedly connected to a second extrusion wheel at one end that passes through the support plate. The outer wall of the second extrusion wheel is in close contact with the measuring ruler.

[0009] In the above technical solution, the support block is further provided with a push rod that is slidably connected through the first extrusion wheel. The outer wall of the push rod is in close contact with the first extrusion wheel. A protrusion is fixedly connected to the outer wall of the push rod, and the protrusion is slidably connected to the support block.

[0010] In the above technical solution, a limiting plate is fixedly connected to the end of the push rod near the first extrusion wheel, and a rubber handle is fixedly connected to the end of the push rod away from the limiting plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) By combining the top plate and the support rod, a simple positioning benchmark is provided for the measurement of the exterior wall. The equipment can be directly attached to the surface of the exterior wall to avoid the positioning deviation caused by the shaking of traditional hand tools. At the same time, the power transmission and steering are realized through the multi-stage transmission structure, ensuring that the measuring ruler moves smoothly in the direction perpendicular to the exterior wall. This effectively solves the problem of ruler body offset in the measurement of the suspended parts of the exterior wall. The accuracy of the measurement data meets the needs of material usage calculation and construction quality verification in the project cost, and provides reliable data support for the cost control of the exterior wall project.

[0012] (2) The convex strip limits the radial offset of the top rod, the guide groove ensures the linear movement of the measuring ruler, the limiting plate avoids excessive travel of the components, and the rubber grip has an anti-slip function. Especially when measuring exterior walls at high altitudes, it can enhance the stability of the operator's hand grip on the equipment and reduce the safety hazards of equipment falling or operation errors due to slipping. At the same time, the overall structure of the equipment does not require the operator to get too close to the suspended area of ​​the exterior wall to complete the measurement, reducing the personal safety risks in high-altitude operations. This allows the equipment to be adapted to various measurement scenarios such as exterior wall masonry, precast panel splicing, and curtain wall installation, improving the work efficiency of exterior wall engineering cost surveying.

Detailed Implementation To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1-4 The construction cost surveying equipment shown includes a support block 1, a guide groove 2 on one side of the support block 1, a guide strip 3 slidably connected in the guide groove 2, a measuring ruler 4 glued to the side of the guide strip 3 away from the guide groove 2, an observation strip 5 fixedly connected to one side of the support block 1 corresponding to the measuring ruler 4, a support rod 6 fixedly connected to the lower end of the support block 1, a top plate 7 fixedly connected to one side of the support rod 6, and a suspended surveying component on the support block 1. The suspended mapping assembly includes a support plate 8 fixedly mounted on the upper end of a support block 1. Two first rotating shafts 9 are rotatably connected to the side of the support plate 8 closest to the support block 1. A first pressing wheel 10 is fixedly connected to the outer wall of each first rotating shaft 9. A first pulley 11 is fixedly mounted on the upper end of one of the first rotating shafts 9. A second rotating shaft 12 is rotatably connected to the side of the support plate 8 furthest from the first rotating shafts 9, with the lower end of the second rotating shaft 12 penetrating the support plate 8. A second pulley 13 is fixedly mounted on the upper end of the second rotating shaft 12. The outer walls of the first pulley 11 and the second pulley 13 are fitted with the same... The step belt 14, the second rotating shaft 12 passes through the support plate 8 and is fixedly connected to the second extrusion wheel 15. The outer wall of the second extrusion wheel 15 is tightly fitted with the measuring ruler 4. The support block 1 is slidably connected to the first extrusion wheel 10. The outer wall of the top rod 16 is tightly fitted with the first extrusion wheel 10. The outer wall of the top rod 16 is fixedly connected to the protrusion 17. The protrusion 17 is slidably connected to the support block 1. The end of the top rod 16 near the first extrusion wheel 10 is fixedly connected to the limit plate 18. The end of the top rod 16 away from the limit plate 18 is fixedly connected to the rubber handle 19.

[0016] Working principle: Before the measurement is started, the operator holds the support rod 6 with his left hand and at the same time tightly attaches the top plate 7 to the outer wall of the part of the building to be measured. The contact between the top plate 7 and the wall forms an overall positioning reference. The support block 1, as the core load-bearing component, stably bears the force of all subsequent transmission structures and avoids the equipment from shaking or shifting due to suspended measurement.

[0017] During measurement, the operator places their right hand on the rubber grip 19 and pushes the push rod 16 toward the support block 1. The push rod 16 slides along the support block 1, and the protrusion 17 fixed on the outer wall of the push rod 16 slides synchronously along the groove on the inner side of the support block 1. The protrusion 17, through clearance fit with the groove, restricts the push rod 16 to move only axially, preventing radial displacement of the push rod 16 and causing transmission failure. At the same time, the push rod 16 drives the limiting plate 18 to move, and the limiting plate 18 limits the push rod 16, playing a role in stroke limit protection.

[0018] The outer wall of the push rod 16 is in close contact with the wheel surface of the first extrusion wheel 10. The axial movement of the push rod 16 drives the first extrusion wheel 10 to rotate around the first rotating shaft 9 through friction. The first extrusion wheel 10 and the first rotating shaft 9 are interference fit, and they rotate synchronously, thereby driving the first pulley 11, which is interference-connected to the top of the first rotating shaft 9, to rotate synchronously. The first pulley 11 transmits the rotational power to the second pulley 13 through the synchronous belt 14 sleeved on the outside. The second pulley 13 rotates at the same speed and in the same direction as the first pulley 11.

[0019] The second pulley 13 is interference-fitted with the top of the second rotating shaft 12. The rotation of the second pulley 13 drives the second rotating shaft 12 to rotate. The rotation of the second rotating shaft 12 directly drives the second pressing wheel 15 to rotate synchronously. The wheel surface of the second pressing wheel 15 is in close contact with the back of the measuring ruler 4. The rotation of the second pressing wheel 15 pushes the measuring ruler 4 to move horizontally through friction.

[0020] When the measuring ruler 4 moves, it drives the guide bar 3 to slide in a straight line along the guide groove 2. The movement trajectory of the measuring ruler 4 is restricted by the cooperation between the guide groove 2 and the guide bar 3, ensuring that the measuring ruler 4 always moves in a direction perpendicular to the wall, and avoiding reading errors caused by the deviation of the measuring ruler 4.

[0021] When the front end of the measuring ruler 4 is pressed against the other outer wall of the part of the building to be measured, the operator stops pushing the top rod 16; at this time, the observation strip 5 fixed on one side of the support block 1 is aligned with the scale line of the measuring ruler 4, and the operator can read the value on the measuring ruler 4 through the baseline of the observation strip 5 to obtain the accurate size of the suspended part of the building and complete the measurement operation.

[0022] The system uses the "manually pushed top rod 16" as the initial power source and achieves power transmission and direction conversion through multi-stage transmission. At the same time, the system is assisted by structures such as the convex strip 17, guide groove 2, and limiting plate 18 to ensure the accuracy and safety of each transmission step. Ultimately, it realizes the measurement of the suspended parts of the building, meets the measurement requirements of right-angled exterior wall dimensions in engineering cost surveying, and provides reliable data support for material usage calculation and construction quality verification.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
