Description

Technical Field

[0001] The invention belongs to the technical field of building measurement, in particular to a device for measuring the width of indoor beams of buildings. Background Art

[0002] Indoor beams usually refer to the load-bearing beams in the room. They play an important role in the structure of the building. When doing interior decoration or architectural design, by measuring the width of the indoor beams, designers can better plan the space layout and avoid the negative impact of beams on space utilization.

[0003] The patent with announcement number CN212007084U discloses a device for measuring the width of indoor beams for construction, including a base, a guide rail and a laser rangefinder. The guide rail is horizontally arranged and installed on the top of the base. The top surface of the guide rail is provided with a slide groove extending along its length direction. The top surface of the guide rail is provided with scale lines extending along the direction of the slide groove. A positioning rod is provided on one side of the guide rail. The positioning rod and the guide rail are arranged parallel to each other. The laser rangefinder is arranged on the guide rail and can slide back and forth along the slide groove. The laser transmitter head of the laser rangefinder is located on its top surface. The device for measuring the width of indoor beams for construction is provided with a base, a guide rail and a laser rangefinder, etc., so that a surveyor can directly measure the width of a building beam on the ground, thereby avoiding the danger caused by the surveyor's climbing and improving the safety of the measurement.

[0004] However, the above technical solution still has the following deficiencies in practical application: When measuring by using a laser rangefinder to emit a laser from one point to another, however, in some cases, the indoor beam wall may not be perpendicular to the ground and may have a certain slope. This may be caused by construction factors, building materials, etc. When this happens, using a laser rangefinder to measure the width will cause errors in the measurement results. In the subsequent construction process, if it is found that the actual width of the beam does not match the design, it will affect the construction. In addition, since the wall is still in the rough stage when measuring the indoor beam width, there may be some dust particles on the surface and protrusions formed on the wall. When the laser is irradiated, it may be blocked by these protruding particles, which in turn affects the accuracy of the measurement results. It is also difficult for staff to know whether the measurement results are interfered with. It is also time-consuming to perform multiple measurements to obtain a more accurate beam width.

[0009] Preferably, one side of the slide plate is fixedly connected to a second motor, and an output end of the second motor is fixedly connected to a gear.

[0010] Preferably, one side of the fixed plate and the adjustment plate are both fixedly connected with an electric push rod 1, and the piston end of the electric push rod 1 is fixedly connected to one side of the displacement plate.

[0011] Preferably, a motor 1 is fixedly connected to one side of the front end surface of the mounting frame, and an output end of the motor 1 is fixedly connected to the middle part of the electrostatic roller.

[0012] Preferably, two sliding rods three are slidably connected to one side of the mounting frame, and a scraper is fixedly connected to one end of the sliding rod three.

Moreover, when the electrostatic roller is close to the wall, the electrostatic roller is energized to absorb impurities on the wall. At the same time, the electrostatic roller is driven to rotate. Since the electrostatic roller is attached to the scraper, the impurities absorbed on the surface of the electrostatic roller will be scraped off by the scraper. That is, while the electrostatic roller adsorbs impurities, it also removes impurities on its surface. When the electrostatic roller contacts the wall, the impurities can avoid affecting the electrostatic roller, further improving the accuracy of detection and avoiding misleading workers. In addition, when the electrostatic roller completes an adsorption work and stops rotating, it drives the push block to move to hit the limit block, and the scraper vibrates with the cooperation of the spring and the slide rod, so that the impurities attached to the inside can be shaken off, thereby ensuring the cleanliness of the inside of the scraper and avoiding the situation where the impurities accumulate too much on the inside of the scraper and move to the surface of the electrostatic roller, affecting its adsorption effect.

[0018] 2. The indoor beam width measuring device for buildings described in the present invention can move the entire device to a designated position using universal wheels, which is relatively convenient. Moreover, when the device is moved to the designated position, the anti-slip pad can be lowered and contacted with the ground by rotating the threaded rod, so that the base can be stabilized, thereby avoiding the situation where the measurement result is affected by the slipping of the base.

[0031] Specifically, when the existing indoor beam width measuring device is used, a laser rangefinder is used to emit a laser, which is irradiated from one point to another point. The distance between the two points is the width of the indoor beam. However, in some cases, the indoor beam wall may not be perpendicular to the ground and may have a certain slope. This may be caused by construction factors, building materials, etc. When this happens, using a laser rangefinder to measure the width will cause errors in the measurement results. In the subsequent construction process, if it is found that the actual width of the beam does not match the design, it will affect the construction. In addition, since the wall is still in the rough stage when measuring the indoor beam width, there may be some dust particles on the surface and bulges are formed on the wall. When the laser is irradiated, it may be blocked by these bulges, thereby affecting the accuracy of the measurement results. It is not easy for the staff to know whether the measurement results are interfered with. It is also time-consuming to perform multiple measurements to obtain a more accurate beam width. Therefore, in order to solve the above problems, when the present embodiment is used, the base 1 is placed under the indoor beam, and then the scissor lift mechanism 3 is used to raise the lifting plate 25, and the left end face of the fixed plate 6 is driven to fit with one side of the indoor beam, and then the motor 26 is used to drive the gear 27 to rotate, so that the slide bar 1 8 can slide from right to left under the action of the tooth block 24, and the spacing between the fixed plate 6 and the adjustment plate 9 is adjusted, and the rising of the adjustment plate 9 is coordinated to make the right end face of the adjustment plate 9 fit with the other side of the indoor beam. At this time, the distance from the right end face of the adjustment plate 9 to the left end face of the fixed plate 6 is the width of the indoor beam, and then the laser rangefinder body 28 is turned on, and the laser transmitter 29 is used to emit laser, and the laser falls on the adjustment plate 9, so that the spacing between the fixed plate 6 and the adjustment plate 9 can be measured, and then the width of the indoor beam can be obtained; Furthermore, after the fixing plate 6 and the adjusting plate 9 are both in contact with the wall, and before the laser rangefinder body 28 is turned on, the electric push rods 10 on both sides are started at the same time, and the electric push rods 10 drive the displacement plate 12 to slide on the sliding rod 2 11, so that the electrostatic rollers 18 on both sides are close to the wall at the same time. If the wall is flat without protrusions and is perpendicular to the ground, the distance between the two electrostatic rollers 18 and the wall is the same, and the two electrostatic rollers 18 will contact the wall at the same time, and the spring damper 13 will be deformed, and the pressure rod 15 will be close to the pressure sensor 14. When the pressure sensor 14 detects pressure, the indicator light 31 will light up. If the two indicator lights 31 light up at the same time, it means that the fixing plate 6 and the adjusting plate 9 are in close contact with the wall. When the width measurement is performed, the measurement result is accurate. When any side of the wall is inclined or has a protrusion, the distance between the two electrostatic rollers 18 and the wall will be different. Then, one side indicator light 31 will light up first. At this time, the distance between the fixed plate 6 and the adjustment plate 9 is not equal to the width of the indoor beam, and the measurement result will be inaccurate, so there is no need to measure. It is necessary to change the measurement position or adopt other processing methods. Therefore, before using the laser rangefinder body 28 to perform the measurement, it is possible to judge whether the fixed plate 6, the adjustment plate 9 and the wall are closely attached to each other, so as to choose whether to measure at this position, thereby avoiding invalid measurement and improving the measurement efficiency and accuracy. Moreover, in some cases, the fixed plate 6 and the adjustment plate 9 are in close contact with the wall surface. However, when the electrostatic roller 18 contacts the wall surface, there may be impurities such as dust and particles at the contact position, and a bulge is formed at the contact position, which will cause the electrostatic roller 18 to be squeezed in advance, and the indicator light 31 on one side will light up first, thereby misleading the measurement personnel. Therefore, in order to avoid this situation, when the electrostatic roller 18 is close to the wall surface, the electrostatic roller 18 is energized, and the electrostatic roller 18 is used to absorb impurities on the wall surface. At the same time, the electrostatic roller 18 is driven to rotate by the motor 17. Since the electrostatic roller 18 is in close contact with the scraper 20, the impurities absorbed on the surface of the electrostatic roller 18 will be scraped off by the scraper 20, that is, while the electrostatic roller 18 absorbs impurities, the impurities on its surface are also removed. When the electrostatic roller 18 contacts the wall surface, the situation that the impurities affect the electrostatic roller 18 can be avoided, which further improves the accuracy of the detection and avoids misleading the workers. Furthermore, since the scraper 20 is used to scrape off impurities on the surface of the electrostatic roller 18, impurities may also accumulate on the inside of the scraper 20. When too many impurities accumulate, these impurities may move to the surface of the electrostatic roller 18, thereby affecting its adsorption effect. Therefore, in order to avoid this situation, when the electrostatic roller 18 completes an adsorption work and stops rotating, the electric push rod 2 16 is used to drive the push block 32 to move to hit the limit block 22, and the spring 23 and the slide rod 3 21 cooperate to make the scraper 20 vibrate so that the impurities attached to the inside are shaken off, thereby ensuring the cleanliness of the inside of the scraper 20 and avoiding the situation where too many impurities accumulate on the inside of the scraper 20 and the impurities move to the surface of the electrostatic roller 18, thereby affecting its adsorption effect.

[0032] In this embodiment, Figure 7 As shown, a display screen 30 is provided on one side of the upper end surface of the laser rangefinder body 28 .

[0033] Specifically, the measured values ​​can be read using the display screen 30, which is relatively convenient.

[0034] In this embodiment, Figure 1 As shown, a plurality of universal wheels 2 are arranged on the lower end surface of the base 1 , threaded rods 4 are arranged on both sides of the base 1 , and anti-slip pads 5 are fixedly connected to the lower ends of the threaded rods 4 .

[0035] Specifically, the entire device can be moved to a designated position using the universal wheel 2, which is relatively convenient. Moreover, when the device is moved to the designated position, the anti-slip pad 5 can be lowered and contacted with the ground by rotating the threaded rod 4, so that the base 1 can be stabilized, thereby avoiding the situation where the measurement result is affected by the slipping of the base 1.

[0036] Working principle: The whole device can be moved to the designated position by the universal wheel 2, which is convenient. When the device moves to the designated position, the anti-skid pad 5 can be lowered and contacted with the ground by rotating the threaded rod 4, so that the base 1 can be stabilized to avoid the situation where the measurement result is affected by the slip of the base 1. The base 1 is placed under the indoor beam, and then the scissor lift mechanism 3 is used to raise the lifting plate 25, and the left end face of the fixed plate 6 is driven to fit with one side of the indoor beam, and then the motor 26 is used to drive the gear 27 to rotate, so that the slide bar 8 can slide from right to left under the action of the tooth block 24. Adjust the distance between the fixed plate 6 and the adjusting plate 9, and coordinate with the rise of the adjusting plate 9 to make the right end face of the adjusting plate 9 fit with the other side of the indoor beam. At this time, the distance from the right end face of the adjusting plate 9 to the left end face of the fixed plate 6 is the width of the indoor beam. Then turn on the laser rangefinder body 28, and use the laser transmitter 29 to emit laser. The laser falls on the adjusting plate 9 to measure the distance between the fixed plate 6 and the adjusting plate 9, and then get the width of the indoor beam. Use the display screen 30 to read the measured value, which is more convenient. Moreover, when the fixed plate 6 and the adjusting plate 9 are both fitted with the wall, and before the laser rangefinder body 28 is turned on, At the same time, the electric push rods 10 on both sides are started, and the electric push rods 10 drive the displacement plate 12 to slide on the sliding rod 2 11, so that the electrostatic rollers 18 on both sides are close to the wall at the same time. If the wall is flat without protrusions and is perpendicular to the ground, the distance between the two electrostatic rollers 18 and the wall is the same, and the two electrostatic rollers 18 will contact the wall at the same time, and the spring damper 13 will be deformed, and the pressure rod 15 will be close to the pressure sensor 14. When the pressure sensor 14 detects pressure, the indicator light 31 lights up. If the two indicator lights 31 light up at the same time, it means that the fixing plate 6 and the adjustment plate 9 are tightly fitted with the wall. At this time, the width measurement work is performed again, and the measurement The result is accurate. When any side of the wall is inclined or has a protrusion, the distance between the two electrostatic rollers 18 and the wall will be different. Then, the indicator light 31 on one side will light up first. At this time, the distance between the fixed plate 6 and the adjustment plate 9 is not equal to the width of the indoor beam, and the measurement result will be inaccurate, so there is no need to measure. It is necessary to change the measurement position or adopt other processing methods. Therefore, before using the laser rangefinder body 28 for measurement, it is possible to judge whether the fixed plate 6, the adjustment plate 9 and the wall are closely attached to each other, so as to choose whether to measure at this position, thereby avoiding invalid measurement and improving measurement efficiency and measurement accuracy.Moreover, in some cases, the fixed plate 6 and the adjustment plate 9 are in close contact with the wall surface. However, when the electrostatic roller 18 contacts the wall surface, there may be impurities such as dust and particles at the contact position, and a bulge may be formed at the contact position, which will cause the electrostatic roller 18 to be squeezed in advance, and the indicator light 31 on one side will light up first, thereby misleading the measurement personnel. Therefore, in order to avoid this situation, when the electrostatic roller 18 is close to the wall surface, the electrostatic roller 18 is energized, and the electrostatic roller 18 is used to absorb impurities on the wall surface. At the same time, the motor 17 is used to drive the electrostatic roller 18 to rotate. Since the electrostatic roller 18 is in contact with the scraper 20, the impurities absorbed on the surface of the electrostatic roller 18 will be scraped off by the scraper 20. That is, while the electrostatic roller 18 absorbs impurities, the impurities on its surface are also removed. When the electrostatic roller 18 contacts the wall surface, the impurities can be prevented from affecting the electrostatic roller 18. The situation further improves the accuracy of detection and avoids misleading workers; and, since the scraper 20 is used to scrape off the impurities on the surface of the electrostatic roller 18, impurities may also accumulate on the inside of the scraper 20. When the impurities accumulate too much, these impurities may move to the surface of the electrostatic roller 18, thereby affecting its adsorption effect. Therefore, in order to avoid this situation, when the electrostatic roller 18 completes an adsorption work and stops rotating, the electric push rod 2 16 is used to drive the push block 32 to move to hit the limit block 22, and the spring 23 and the slide rod 3 21 cooperate to make the scraper 20 vibrate, so that the impurities attached to the inside can be shaken off, thereby ensuring the cleanliness of the inside of the scraper 20, and avoiding the situation that the impurities accumulate too much on the inside of the scraper 20 and move to the surface of the electrostatic roller 18, affecting its adsorption effect. ;
