Description

Technical Field

[0001] The invention belongs to the technical field of measuring instruments, and in particular relates to a high-efficiency roof slope measuring instrument. Background Art

[0002] Roofing project is one of the main parts of housing construction project. It includes the materials, equipment and technical activities such as design, construction, maintenance, etc. used in the project. It also refers to the object of project construction and plays a role in functional guarantee. In order to facilitate the detection of roof slope during the construction process, corresponding slope measuring devices are often used.

[0003] Our company applied for patent number "2023223148722" on August 28, 2023. The patent name is "A roof slope measuring device", which records "The utility model discloses a roof slope measuring device, which relates to the field of slope detection technology, including a protective shell, a laser emitter is arranged inside the protective shell, the protective shell is fixedly connected to the outer wall of the rotating button, the rotating button is arranged inside the fixed seat, the rotating button is rotatably connected to the fixed seat, the fixed seat is fixedly connected to the top of the rotating seat, the rotating seat is fixedly connected to the top of the needle disk, the needle disk is movably connected to the top of the scale plate, and the scale plate is fixedly connected to the top of the support base. The utility model adjusts the length of the three by rotating the thread of the adjusting column, the long rod and the tapered rod, thereby adjusting the height of the starting point of the device, and the adjusting column itself can also adjust the height of the starting point of the device again by pulling and retracting, which solves the problem that the traditional measuring device cannot adjust the height of its own starting point, making the device more convenient in use."

[0004] However, during use, we found that the above-mentioned prior art measuring device still has the following shortcomings: First, although the roof slope device of the prior art solves the problem of height adjustment and movement to a certain extent, it requires the staff to manually rotate the adjustment column to achieve it. Such an operation method is time-consuming and labor-intensive, which seriously restricts the efficiency of slope measurement operations at a large number of measuring points on the roof slope. At the same time, there are errors in manual adjustment, which will also seriously affect the accuracy of slope measurement. Further analysis shows that the use of the support frame and spare frame of the above-mentioned measuring device and the movement of the wheels are not related, that is, the adjustment of the measurement working state and the movement state of the above-mentioned measuring device lacks relevance. At the same time, after the height travel of the support frame and the spare frame is adjusted, the wheel is in contact with the ground at this time, and then the use of partial stacking height can be achieved by rotating the sleeve. However, at this time, as a measuring state, the wheel is not fixed due to sliding and position offset, which is easy to cause measurement errors. Second, the measurement method adopted by the roof slope device in the prior art is relatively simple, and the factors of sampling quantity and measurement signal acquisition and processing are particularly important. That is, in the actual measurement operation of the roof slope, the signal measurement lacks calibration, and direct comparison with the roof surface is likely to cause benchmark deviation. At the same time, the acquisition and processing of the measurement signal and the storage and transmission of the data in the actual measurement process of the above-mentioned measurement device are not intelligent enough, resulting in low measurement accuracy of the roof slope.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0022] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0023] Example 1: Figure 1-Figure 8 As shown: An efficient roof slope measuring instrument includes a support frame 1, a measuring component 2 and a calibration component 3. The measuring instrument has a compact overall structure and a reasonable design, which can improve the efficiency of roof slope measurement by at least 15%, while also further improving the measurement accuracy. The support frame 1 includes a fixed seat 11 and a support leg 12. The fixed seat 11 is vertically distributed, and the fixed seat can adopt a cylindrical structure. The support leg 12 is telescopically arranged on the fixed seat 11, and the two can be relatively rotatable. Specifically, as Figure 3As shown: the support leg 12 includes a hinged plate 121, a connecting rod 122, a connecting sleeve 123 and a movable plate 124. The hinged plate 121 is hingedly mounted on the fixed seat 11, and there are two connecting rods distributed on both sides. One end of the connecting rod 122 is arranged on the hinged plate 121, and the other end is connected to the connecting sleeve 123, and a sliding connection is maintained between the connecting rod 122 and the connecting sleeve 123. Among them, the connecting sleeve 123 and the movable plate 124 are an integrally formed structure, the movable plate is arranged between the two connecting rods, and the movable plate and the connecting rod can be connected by keyway cooperation, and a travel limit is set at the end. A support pin 125 is provided at the bottom end of the movable plate 124. The purpose of such a setting is to facilitate the reasonable adjustment of the deflection angle of the support leg, thereby realizing the adjustment of the measurement height. Among them, in a preferred embodiment, the support legs are three groups evenly distributed in a ring.

[0024] like Figure 4 As shown: In this embodiment, a movable structure 13 is further provided below the fixed seat 11, wherein the movable structure 13 includes a connecting arm 131, a base 132 and a universal wheel 133. The connecting arms 131 are vertically distributed and are multiple and evenly distributed in a ring shape; the base 132 is horizontally distributed and is connected and fixed to the bottom end of the connecting arm 131, and the universal wheel 133 is set on the base 132 through a bracket. The purpose of setting the universal wheel is to ensure the convenience of movement. An electric hydraulic telescopic rod 134 is also provided at the lower end of the base 132. The electric hydraulic telescopic rod 134 is connected to a switch button 135, and one end is connected to the base 132, and the other end is connected to a pad 136; in the initial state, the electric hydraulic telescopic rod 134 and the pad are integrally retracted, and the height is less than the setting height of the universal wheel 133. For details, refer to Figure 7 The structure shown. With such a setting, the first stage of measurement height adjustment can be achieved while ensuring the high efficiency of movement under different measuring points, saving time and effort. A battery compartment is provided inside the fixing seat, and a battery is installed in the battery compartment to power electrical components such as the LED control panel.

[0025] like Figure 1As shown: wherein, a driving member 14 is also provided between the connecting arm 131 and the fixing seat 11, so that when the base 132 reaches the preset first height, the supporting leg 12 is driven to expand outward until the supporting leg 12 forms an angle of 30 degrees with the central axis of the fixing seat 11, at which time the universal wheel 133 does not touch the ground; this process is mainly achieved by changing the deflection angle of the supporting leg to adjust the measurement height. When the base 132 reaches the preset second height, the supporting leg 12 is driven to expand outward until the supporting leg 12 forms an angle of 45 degrees with the central axis of the fixing seat 11, at which time the universal wheel 133 touches the ground, and the bottom of the supporting leg 12 begins to leave the ground; in this process, the universal wheel contacts the ground and begins to form a moving state. In this state, it is convenient to realize the movement of measuring multiple position points, and at the same time, the relative change of the height of the universal wheel and the electric hydraulic telescopic rod can be used to realize the free switching between the moving state and the fixed state of the measuring position.

[0026] In a preferred embodiment, Figure 2 As shown: the driving member 14 includes a mounting plate 141, a driving motor 142, a rotating lead screw 143, a guide rod 144, a sleeve 145, and a bearing plate 146. The mounting plate 141 is arranged at the lower end of the fixed seat 11, and serves as a mounting carrier for the driving motor. The driving motor 142 is fixedly mounted on the mounting plate 141, wherein the driving motor adopts a servo control motor, and the displacement parameter control is more accurate. The rotating lead screw 143 is vertically distributed and connected to the output shaft of the driving motor 142; with such an arrangement, the driving motor drives the rotating lead screw to rotate synchronously. The guide rod 144 is a plurality of evenly distributed annular guide rods, and the guide rods 144 are vertically distributed, one end of which is connected to the mounting plate 141 and the other end is connected to the bearing plate 146, and the guide rods 144 and the bearing plate 146 are fixed by welding; with such an arrangement, a supporting frame structure is formed. The sliding sleeve 145 is movably arranged on the rotating screw 143 and the guide rod 144, and the sliding sleeve 145 is threadedly connected to the rotating screw 143, and the sliding sleeve 145 is slidingly connected to the guide rod 144; the sliding sleeve is an annular structure. A driving arm 147 is also arranged between the sliding sleeve 145 and the connecting sleeve 123, and the driving arm 147 is hinged to both. The sliding sleeve and the bearing plate are both annular and have the same size and structure. The base is circular, and the outer diameter is larger than the outer diameter of the sliding sleeve. The connecting arm is located outside the sliding sleeve, and the top of the connecting arm is connected and fixed to the sliding sleeve through a connecting protrusion, and the connecting protrusion is fixed to the connecting arm and the sliding sleeve by welding.

[0027] With such a configuration, the driving motor drives the rotating screw to rotate synchronously, which in turn drives the sliding sleeve to move up and down. When the driving motor rotates forward, it drives the sliding sleeve to move downward, which in turn changes the tilt distribution of the driving arm. The driving arm drives the supporting leg to gradually unfold as a whole. During this process, the universal wheel is always not in contact with the ground. This process mainly relies on the extension and deflection angle change of the supporting leg to achieve the adjustment of the supporting height. The driving member 14 shown also includes an infrared ranging sensor 148, which is fixedly mounted on the sliding sleeve 145, and the infrared ranging sensor 148 maintains a signal connection with the driving motor 142. The sliding sleeve 145 is also connected to the top of the connecting arm 131. By initially setting the first height of the infrared ranging sensor, that is, the downward displacement height value of the base when the central axis of the supporting leg 12 and the fixing seat 11 is 30 degrees. The second height is the downward displacement height of the base when the central axis of the supporting leg 12 and the fixing seat 11 is 45 degrees. In this state, the bottom of the support leg and the universal wheel are in contact with the ground, and the support leg begins to leave the ground. The drive motor continues to drive the sleeve downward, and the sleeve also drives the base to continue to move downward, which is also the second stage of adjusting the measurement height; at the same time, the relative height change of the universal wheel and the electric hydraulic telescopic rod can realize the free switching between the mobile state and the fixed state of the measurement position.

[0028] like Figure 5 As shown: In this embodiment, the calibration component 3 includes a calibration rod 31, a base 32, a top seat 33 and a laser emitter 34.

A prism protective cover 37 is also provided on the outside of the laser emitter 34, and the prism protective cover is fixedly installed on the top seat 33. The calibration rod 31 includes a tube body 311 and an electric hydraulic lifting rod 312. As shown Figure 6 As shown: the tube body 311 is vertically distributed, and a cavity 313 is provided inside, and a lithium battery 314 is provided in the cavity for powering the laser emitter. The top of the tube body 311 is connected and fixed to the base 132; one end of the electric hydraulic lifting rod 312 is connected to the tube body, and the other end is connected to the base 32. The purpose of such a setting is to quickly adjust the setting height of the laser emitter, provide a strong benchmark for subsequent slope measurement and improve the test efficiency. The base 32 and the end of the electric hydraulic lifting rod 312 are connected by threads. The fixing seat 11 is provided with a mounting hole 111 for adapting and installing the calibration rod 31. In the initial state, the calibration rod 31 is embedded in the fixing seat 11. Such a setting is convenient for installation and carrying. At the same time, in the initial carrying state, it is embedded in the fixing seat, saving time and effort.

[0031] like Figure 8 As shown: wherein, the controller 25 includes a signal filtering processing module 251, a signal acquisition module 252, a signal calculation module 253 and a signal data storage module 254.
