Description

Technical Field

[0001] The present invention relates to the field of building measurement, and in particular to an industrial heritage measurement system, a measurement method and a measurement device. Background Art

[0002] Industrial heritage refers to all buildings and structures built for industrial activities, the craftsmanship and tools contained in such buildings and structures, the towns and landscapes in which such buildings and structures are located, and all other material and non-material manifestations of such buildings and structures, all of which are of vital importance. Industrial heritage includes industrial cultural relics with historical, technological, social, architectural or scientific value, including buildings, machinery, factories, production workshops and factory mines, as well as processing and refining sites, etc., which have extremely high cultural value.

[0003] In a Chinese patent with the patent publication number CN113155095A, a slope measuring device for construction engineering supervision and a method of using the same are disclosed, including a base plate, a box body is fixedly connected to the top of the base plate, a moving wheel is fixedly connected to the bottom of the base plate, a push handle is fixedly connected to one side of the base plate, a measuring mechanism is arranged on the top of the box body, a horizontal adjustment mechanism is arranged on the bottom of the box body, and the measuring mechanism includes a driving motor and a measuring system. The present invention relates to the field of construction engineering technology. The slope measuring device for construction engineering supervision and a method of using the same are provided with a measuring mechanism, and a driving motor is used to drive the rotation of the driving shaft, so that the screw rod rotates, and the rotating bearing, the first moving block and the second moving block move, and the detection plate is driven to move by the second cylinder at the same time, which can not only better measure the lateral and longitudinal distances of the slope, but also can continuously adjust the position and perform multi-point detection, thereby improving the data accuracy of the slope measurement.

[0004] However, the following defects still exist in the specific use of the comparative documents:

[0005] 1. In the comparative document, the third cylinder is used to drive the movement of the third push rod, so that the support plate and the fixed plate move downward until they contact the ground, and the threaded column is driven to rotate by turning the adjusting dial, so that the entire base plate is in a horizontal state. However, the corresponding extension or shortening of the pillar cannot be controlled, which will cause it to still be unable to maintain balance on an inclined or uneven bottom surface. The inability of the measuring device to maintain balance will cause the error of a single measurement to increase. As the number of measurements increases, these errors will continue to accumulate, and ultimately lead to serious deviations in the overall measurement results.

[0006] 2. The comparative documents do not provide protection for the measuring device. When measuring a building, it is usually necessary to move the measuring device to different points to be measured. During the movement and transportation, due to the unevenness of the bottom surface or the carelessness of the staff, the measuring device may be subjected to physical damage such as impact and bumps, resulting in the loss of the accuracy of the measuring element, thereby affecting the accuracy of the measurement results.

[0007] Therefore, an industrial heritage measurement system, measurement method and measurement device are proposed to solve the above problems. Summary of the invention

[0047] Embodiment 2

[0048] Please refer to Figures 1 to 3 As shown:

[0049] In order to solve the problems mentioned in the technical solution, an embodiment of the present application provides an industrial heritage measuring device, including: a base 1, a support plate 11 is fixedly connected to the top surface of the base 1, a measuring instrument body 12 is rotatably connected to the inner wall of the support plate 11, a measuring lens 13 is fixedly connected to the outer surface of the measuring instrument body 12, a storage protection mechanism 2 is provided on the top surface of the base 1, and a balance maintaining mechanism 3 is provided on the bottom surface of the base 1.

[0050] The storage protection mechanism 2 includes an electric telescopic rod 21, which is circumferentially fixedly connected to the bottom surface of the base 1, and one end of the electric telescopic rod 21 away from the base 1 is fixedly connected to a connecting plate 22, and a plurality of rollers 14 are provided on the bottom surface of the electric telescopic rod 21. A first compression cylinder 23 is fixedly connected between the base 1 and the electric telescopic rod 21, and a second compression cylinder 24 is fixedly connected to the top surface of the connecting plate 22.

[0051] The outer surface of the bottom end of the second compression cylinder 24 is fixedly connected to a connecting pipe 25, and the other end of the connecting pipe 25 is fixedly connected to the outer surface of the support plate 11, and a plurality of nozzles are arranged on the top of the connecting pipe 25. The bottom surface of the inner wall of the second compression cylinder 24 is fixedly connected to a contact 26, and the bottom surface of the base 1 is fixedly connected to a pressing plate 27, and the pressing plate 27 is located above the second compression cylinder 24.

[0052] A protective frame 28 is fixedly connected to the top surface of the base 1, and the protective frame 28 is located on the outer surface of the support plate 11. An electric telescopic plate 29 is fixedly connected to the top surface of the protective frame 28. A side of the measuring instrument body 12 close to the measuring lens 13 is rotatably connected to a ring 210, and the ring 210 is located on the outer surface of the measuring lens 13. The ring 210 is provided with an arc groove, and a baffle 211 is slidably connected in the arc groove.

[0053] Among them: the staff can drive the electric telescopic rod 21 to extend and retract through the driving device, the top outer surface of the connecting tube 25 is provided with a nozzle, the contact 26 is electrically connected with the electric telescopic plate 29 and the ring 210, that is, when the contact 26 is touched, the ring 210 is controlled to rotate and the electric telescopic plate 29 is contracted. Since the ring 210 is provided with an arc groove, and the baffle 211 is slidably connected in the arc groove, that is, when the contact 26 is touched, the ring 210 rotates, and the electric telescopic plate 29 will also extend accordingly, and the measuring lens 13 is protected inside the ring 210 by the sliding of the baffle 211.

[0054] Compared with the comparative document, through the implementation of this embodiment, the contraction of the electric telescopic rod 21 can drive the pressure plate 27 to move up and down, thereby driving the second compression cylinder 24 to contract, and then the gas in the second compression cylinder 24 is sprayed toward the measuring lens 13 through the connecting pipe 25, thereby cleaning the measuring lens 13.

Compared with manual cleaning, air blowing cleaning will not cause friction of the wiping tool on the surface of the measuring lens 13, thereby avoiding wear on the measuring lens 13. In addition, air blowing cleaning can also effectively prevent static electricity from adsorbing the measuring lens 13, thereby avoiding dust and other impurities from adhering to the surface of the measuring lens 13 again.

[0055] For further examples, please refer to Figures 4 to 7 As shown:

[0056] The balance maintaining mechanism 3 includes four first telescopic rods 31, which are rotatably connected to the bottom surface of the connecting plate 22, and one end of the four first telescopic rods 31 away from the connecting plate 22 is rotatably connected to a supporting circular plate 32, and a plurality of rubber pads are provided on the bottom surface of the supporting circular plate 32, an auxiliary cylinder 34 is fixedly connected to the bottom surface of the base 1, and four warning lights 33 are fixedly connected to the top surface of the base 1.

[0057] The bottom end of the auxiliary cylinder 34 is fixedly connected to an auxiliary disc 35, and four contact rings 36 are arranged on the bottom surface of the auxiliary disc 35. The bottom end of the auxiliary cylinder 34 is fixedly connected to an auxiliary ball 39, and the outer surface of the auxiliary ball 39 is rotatably connected to an auxiliary cylinder 37. A protective cover is arranged on the top surface of the auxiliary cylinder 37, and the protective cover protects the auxiliary ball 39.

[0058] Among them: a plurality of rubber pads are arranged on the bottom surface of the supporting circular plate 32, the contact ring 36 is electrically connected with the warning light 33 and the first telescopic rod 31, a protective cover is arranged on the top surface of the auxiliary cylinder 37, and four contact rings 36, four first telescopic rods 31 and four warning lights 33 correspond to each other.

[0059] Compared with the comparative document, through the implementation of this embodiment, the auxiliary cylinder 37 is tilted by tilting the weight block 38, and then the protective cover provided on the auxiliary cylinder 37 is driven to touch the touch ring 36, and then the first telescopic rod 31 corresponding to the touch ring 36 is extended, so that the measuring instrument body 12 is kept balanced. This design allows local adjustment of the first telescopic rod 31, that is, according to the degree and direction of inclination of the weight block 38, the extension of the first telescopic rod 31 is adjusted in a targeted manner, so as to more accurately maintain the balance of the measuring instrument body 12, while the design in the comparative document can only achieve overall extension and cannot perform local adjustment according to specific circumstances. Therefore, in some cases, the best balance effect may not be achieved, which will bring limitations to the measurement of buildings.

[0060] Embodiment 3

[0061] Measurement methods include:

[0062] Step 1: When it is necessary to measure a building, the ring 210 is driven to rotate and the electric telescopic rod 21 is extended by the driving device in advance, thereby releasing the protection of the measuring lens 13 to ensure accurate measurement;

[0063] Step 2: After the building measuring device is moved to the point to be measured by the roller 14, the corresponding touch ring 36 can be touched according to the inclination angle of the auxiliary cylinder 37, thereby driving the first telescopic rod 31 to extend, so that the measuring instrument body 12 can be kept balanced;

[0064] Step 3: When measuring at a different location, control the electric telescopic rod 21 to contract so that the pressure plate 27 squeezes the second compression cylinder 24 and blows air to the measuring lens 13 through the connecting tube 25. When the second compression cylinder 24 is compressed and touches the contact point 26, control the ring 210 to reverse and protect the measuring lens 13.

[0065] Everything in the above example works like this:

[0066] In the initial state: the electric telescopic rod 21 is in a retracted state, and the baffle 211 protects the measuring lens 13 inside the ring 210 .

[0067] The following is the working process of the storage protection mechanism 2 cleaning and protecting the measuring lens 13:

[0068] When in use, the staff moves the measuring device to the point to be measured through the roller 14, and then the staff controls the electric telescopic rod 21 to extend. The extension of the electric telescopic rod 21 drives the base 1 fixedly connected thereto to extend, thereby stretching the compressed second compression cylinder 24. Since the bottom surface of the inner wall of the second compression cylinder 24 is fixedly connected with the contact 26, when the second compression cylinder 24 is stretched, the contact 26 is no longer touched, and the contact 26 is electrically connected to the ring 210, that is, when the contact 26 is no longer touched, the ring 210 rotates to move the baffle 211. The measuring lens 13 is released from the inside of the ring 210, and the measuring lens 13 is no longer protected. Then the building is measured through the measuring instrument body 12. After the measurement, the electric telescopic rod 21 is retracted to control the overall height of the base 1 to prevent it from tipping over when it moves through the rollers 14, thereby enhancing the safety of the device when moving. In addition, in different application scenarios, the overall height of the device is controlled by retracting the electric telescopic rod 21, so that the device can better adapt to these space limitations and improve the passability.

[0069] When the electric telescopic rod 21 contracts, the second compression cylinder 24 is squeezed, so that the gas in the second compression cylinder 24 is squeezed to the surface of the measuring lens 13 through the connecting tube 25, and a nozzle is provided at one end of the connecting tube 25 close to the measuring lens 13, so that the surface of the measuring lens 13 is blown, thereby cleaning the measuring lens 13. By blowing, dust, dirt and other impurities on the surface of the measuring lens 13 can be quickly blown away to achieve rapid cleaning. Compared with manual cleaning, air blowing cleaning will not cause friction of the wiping tool on the surface of the measuring lens 13, thereby avoiding wear on the measuring lens 13. In addition, air blowing cleaning can also effectively prevent static electricity from adsorbing the measuring lens 13, thereby avoiding dust and other impurities from adhering to the surface of the measuring lens 13 again. At the lowest level, the contact 26 will be squeezed. Since the contact 26 is electrically connected to the electric telescopic plate 29 and the ring 210, the ring 210 is driven to rotate. The rotation of the ring 210 drives the baffle 211 to move toward each other, thereby protecting the measuring lens 13 inside the ring 210, and the electric telescopic plate 29 will also extend accordingly. Protecting the measuring lens 13 inside the ring 210 can reduce its direct contact with the external environment, thereby reducing wear and corrosion caused by friction, oxidation and other factors, which helps to extend the service life of the components and improve the overall performance of the equipment. For some components that require high precision, protecting them inside can reduce the impact of environmental factors such as temperature and humidity on their accuracy. For example, during precision measurement, this design can ensure that the accuracy of the components remains stable for a long time.

[0070] Please refer to the above working process Figures 1 to 3 .

[0071] The following is the working process of maintaining the balance of the balancing mechanism 3 position measuring instrument body 12:

[0072] When in use, when the measuring device is at an uneven or tilted measuring point, the weight block 38 will tilt with the overall tilt of the device, and the tilt of the weight block 38 will cause the auxiliary cylinder 37 to tilt together, and the weight block 38 is protected by the first compression cylinder 23 and will not be affected by external factors. Since the top surface of the auxiliary cylinder 37 is provided with a protective cover, and since the bottom surface circumference of the auxiliary disc 35 is provided with four touch rings 36 corresponding to the four first telescopic rods 31, when the auxiliary cylinder 37 tilts and touches the touch ring 36, the corresponding warning light 33 will light up to warn the worker. The measuring device is not in a stable state, and the corresponding first telescopic rod 31 will also extend accordingly, thereby adjusting the stability of the measuring device. This design allows local adjustment of the first telescopic rod 31, that is, according to the inclination and direction of the load block 38, the extension of the first telescopic rod 31 is adjusted in a targeted manner, so as to more accurately maintain the balance of the measuring instrument body 12. The design in the comparative document can only achieve overall extension and cannot perform local adjustment according to specific circumstances. Therefore, in some cases, the best balance effect may not be achieved, which will bring limitations to the measurement of buildings.
