A measuring device for construction size of engineering cost

Abstract

This invention discloses a measuring device for construction dimensions of engineering cost estimates, relating to the field of surveying devices. It includes a protective plate, an adjusting component within the inner cavity of the protective plate, and a protective component positioned above the adjusting component. The adjusting component adjusts the angle of the protective component, while the protective component limits the measuring instrument. This measuring device for construction dimensions of engineering cost estimates uses a sliding block to slide along the inner wall of a groove, thereby moving an arc-shaped plate around a sphere. This moves the protective component mounted on a limiting block to a suitable position, meeting the required measurement standards. A movable block moves downward, squeezing a drive plate to rotate around its connection with a fixed block. This causes the end of the drive plate away from the fixed block to move downward, fixing the measuring instrument and preventing it from slipping during use.

Description

Technical Field

[0001] This invention relates to surveying device technology, specifically to a measuring device for engineering cost and construction dimensions. Background Technology

[0002] Construction project cost generally refers to the expenses incurred in carrying out a construction project, that is, all costs from planning to completion and acceptance. It consists of construction and installation costs, equipment and tool purchase costs, other construction costs, contingency costs, and taxes. Since the project cost is usually related to the building area, it is often necessary to measure the area and dimensions of the building in construction project cost estimation. There are many types of measuring devices, such as tape measures or total stations. The use of these measuring devices makes it easier for staff to measure the dimensions of the building, thereby facilitating the calculation of project cost.

[0003] Chinese invention patent CN115218080A discloses a precision measuring device for construction engineering cost estimation. This device, proposed in this invention, facilitates the use and storage of the precision measuring device through a supporting and fixing structure, a lifting and storage structure, and a dual-axis motor. The included protective storage compartment effectively protects the measuring device when not in use. The fixing components further enhance the horizontal adjustment and fixation of the measuring device; these components also allow for fine-tuning of the device's level, resulting in more accurate measurements.

[0004] Currently, most measurement work is carried out manually on-site by technicians holding or carrying measuring devices. During the measurement process, the measuring angle and placement angle of the entire device are adjusted by personnel. This not only results in a large workload for personnel, but also the accuracy of the measurement data depends mainly on the quality of the technicians. Furthermore, uncontrollable human factors can affect the accuracy of the measurement results. Therefore, a measuring device for construction dimensions of engineering cost has been developed. Summary of the Invention

[0005] The purpose of this invention is to provide a measuring device for construction dimensions of engineering costs, so as to overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a measuring device for construction dimensions of engineering cost, comprising a protective plate, wherein an adjusting component is provided in the inner cavity of the protective plate, and a protective component is provided at the upper end of the adjusting component, wherein the angle of the protective component is adjusted by the adjusting component, and the protective component limits the measuring device.

[0007] The adjustment component includes a base plate fixedly connected to the protective plate, and the base plate has an L-shaped cross-section. A slide rod is slidably installed at one end of the base plate, and a snap-fit ​​block is fixedly installed at one end of the slide rod. A slot is provided at one end of the snap-fit ​​block, and a ball is slidably installed on the inner wall of the slot. A telescopic component is fixedly installed on the outer surface of the ball, and a limit block is fixedly installed at the end of the telescopic component away from the ball. The angle between the limit block and the protective component is adjusted.

[0008] As a further optimization of the present invention, an arc-shaped plate is slidably installed on the inner wall of the limiting block, and an movable groove is opened on the outer surface of the arc-shaped plate. Multiple sets of protrusions are installed at a height on one side of the inner wall of the movable groove and are evenly distributed on one side of the inner wall of the movable groove.

[0009] As a further optimization of the present invention, a power component is fixedly installed on one side of the limiting block, and the output end of the power component penetrates and extends into the interior of the limiting block. A gear is fixedly installed on the output end of the power component, and the outer surface of the gear meshes with the outer surface of the protrusion.

[0010] As a further optimization of the present invention, a groove is provided on one side of the base plate and below the arc-shaped plate, and a slider is slidably installed on the inner wall of the groove, with the upper end of the slider being rotatably connected to the lower end of the arc-shaped plate.

[0011] As a further optimization of the present invention, the protective component includes a connecting plate fixedly connected to the limiting block. Two limiting plates are provided at the upper end of the connecting plate, and a fixing block is fixedly installed at the opposite end of each of the two limiting plates. A through hole is provided on one side of the fixing block.

[0012] As a further optimization of the present invention, a movable block is slidably installed between the two fixed blocks, and positioning blocks are fixedly installed at both ends of the movable block, and the outer surface of the positioning block is slidably connected to the inner wall of the through hole.

[0013] As a further optimization of the present invention, a drive rod is rotatably mounted on one end of the movable block, and a drive component is rotatably mounted on the lower end of the drive rod, while the lower end of the drive component is fixedly connected to the upper end of the connecting plate.

[0014] As a further optimization of the present invention, a limiting plate is rotatably mounted on the end of the movable block away from the driving rod, a driving plate is rotatably mounted on the middle part of the limiting plate, and the end of the driving plate away from the limiting plate is rotatably connected to one side of the fixed block, and a clamping plate is fixedly mounted on the upper end of the driving plate.

[0015] As a further optimization of the present invention, a stop plate is rotatably installed between the two fixed blocks and below the drive plate, and the middle part of the stop plate is rotatably connected to the end of the limiting plate.

[0016] Compared with the prior art, the present invention provides a measuring device for construction dimensions of engineering cost. By driving the slider to slide on the inner wall of the groove, the arc plate moves around the sphere, so that the protective component installed on the limit block moves to the appropriate position and meets the required measurement standards. By moving the movable block downward, the drive plate is squeezed to rotate around the connection with the fixed block, so that the end of the drive plate away from the fixed block moves downward and fixes the measuring instrument so that it will not slip during use.

[0027] Example:

[0028] Please see Figure 1 - Figure 5 A measuring device for construction dimensions of engineering cost includes a protective plate 1, an adjusting component 2 is provided in the inner cavity of the protective plate 1, and a protective component 3 is provided at the upper end of the adjusting component 2. The angle of the protective component 3 is adjusted by the adjusting component 2, and the protective component 3 limits the measuring device.

[0029] In this solution, the instruments required for measurement are clipped onto the protective component 3 to ensure that the measuring instruments will not slip when the angle is adjusted. At the same time, the measuring instruments can be removed when not in use. In order to prevent external dust from affecting the measuring instruments, a transparent dust cover can be placed on the upper end of the protective plate 1 to prevent external dust from affecting the measurement results. A tripod is set at the lower end of the protective plate 1 to support the entire device and adjust to a suitable height. A storage box is set below the protective plate 1 to store the measuring instruments.

[0030] The adjusting component 2 includes a base plate 21 fixedly connected to the protective plate 1, and the cross-section of the base plate 21 is L-shaped. A slide rod 22 is slidably installed at one end of the base plate 21, and a snap-fit ​​block 23 is fixedly installed at one end of the slide rod 22. At the same time, a slot 24 is opened at one end of the snap-fit ​​block 23, and a ball 25 is slidably installed on the inner wall of the slot 24. A telescopic component 26 is fixedly installed on the outer surface of the ball 25. A limit block 261 is fixedly installed at the end of the telescopic component 26 away from the ball 25. The angle between the telescopic component 26 and the protective component 3 is adjusted by the limit block 261.

[0031] Specifically, the ball 25 is located on the inner wall of the snap-fit ​​block 23, so that the angle of the telescopic member 26 can be adjusted when the ball 25 rotates. At the same time, the telescopic member 26 is composed of a cylinder and a rod. The outer surface of the rod is connected to the inner wall of the cylinder. The end of the cylinder away from the rod is fixedly connected to the ball 25, and the end of the rod away from the cylinder is fixedly connected to the limiting block 261.

[0032] Furthermore, an arc-shaped plate 27 is slidably installed on the inner wall of the limiting block 261. An movable groove 271 is opened on the outer surface of the arc-shaped plate 27, and multiple sets of protrusions 272 are installed on one side of the inner wall of the movable groove 271 and are evenly distributed on one side of the inner wall of the movable groove 271.

[0033] A power component 28 is fixedly installed on one side of the limiting block 261. At the same time, the output end of the power component 28 passes through and extends into the interior of the limiting block 261. A gear 281 is fixedly installed on the output end of the power component 28. The outer surface of the gear 281 meshes with the outer surface of the protrusion 272.

[0034] In this embodiment, the driving component 28 is a device with power output such as a motor. When the driving component 28 is started, it drives the gear 281 inside the limiting block 261 to rotate. Since the outer surface of the gear 281 meshes with the protrusion 272 on the inner wall of the movable groove 271 and rotates around the ball 25, the angle of the entire limiting block 261 is adjusted until it reaches the appropriate position.

[0035] Furthermore, a groove 211 is provided on one side of the base plate 21 and below the arc plate 27. A slider 212 is slidably installed on the inner wall of the groove 211, and the upper end of the slider 212 is rotatably connected to the lower end of the arc plate 27.

[0036] Specifically, the inner wall of the slide 211 is equipped with a device with power output, such as an electric telescopic rod. When the electric telescopic rod is activated, it drives the slider 212 to slide on the inner wall of the slide 211, thereby driving the arc plate 27 to move around the sphere 25, so that the protective component 3 installed on the limit block 261 moves to the appropriate position and meets the standards required for measurement.

[0037] Furthermore, the protective component 3 includes a connecting plate 31 fixedly connected to the limiting block 261. The upper end of the connecting plate 31 is provided with two limiting plates 32. A fixing block 33 is fixedly installed on the opposite end of each of the two limiting plates 32. A through hole 331 is opened on one side of the fixing block 33.

[0038] A movable block 34 is slidably installed between two fixed blocks 33. Positioning blocks 343 are fixedly installed at both ends of the movable block 34, and the outer surface of the positioning block 343 is slidably connected to the inner wall of the through hole 331.

[0039] In this design, the movable block 34 is confined between two fixed blocks 33 by the positioning block 343, and moves within the inner wall of the through hole 331. Specifically, a protrusion is provided below the end of the movable block 34, which drives the protrusion to move downward when the movable block 34 moves within the inner wall of the through hole 331.

[0040] Furthermore, a drive rod 341 is rotatably mounted on one end of the movable block 34, and a drive component 342 is rotatably mounted on the lower end of the drive rod 341. At the same time, the lower end of the drive component 342 is fixedly connected to the upper end of the connecting plate 31.

[0041] Specifically, the driving component 342 is a device with power output, such as an electric telescopic rod, so that when the driving component 342 is started, it pushes the driving rod 341 to move, and the driving rod 341 pushes the movable block 34 to slide on the inner wall of the through hole 331, thereby moving the movable block 34.

[0042] Furthermore, a limiting plate 37 is rotatably mounted on the end of the movable block 34 away from the drive rod 341, and a drive plate 35 is rotatably mounted on the middle part of the limiting plate 37. At the same time, the end of the drive plate 35 away from the limiting plate 37 is rotatably connected to one side of the fixed block 33, and a clamping plate 351 is fixedly mounted on the upper end of the drive plate 35.

[0043] In this scheme, the movable block 34 moves downward, thereby squeezing the drive plate 35 to rotate around the connection with the fixed block 33, so that the end of the drive plate 35 away from the fixed block 33 moves downward and fixes the measuring instrument.

[0044] Furthermore, a stop plate 36 is rotatably mounted between the two fixed blocks 33 and below the drive plate 35, and the middle part of the stop plate 36 is rotatably connected to the end of the limiting plate 37.

[0045] Specifically, the limiting plate 37 is limited by the abutment plate 36, and the abutment plate 36, together with the clamping plate 351, fixes the measuring instrument so that it will not slip during use.

[0046] All electrical components described in this solution are connected to an external control unit and controlled by the control unit.

[0047] The control device can use a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.

[0048] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
