[0020] Optionally, the measuring method of the area measuring device for building construction comprises the following steps:

[0021] S1. First, move the carrier to the edge of the construction site. After determining the starting point, pull out the positioning rod from the card plate on the side surface of the measuring box, insert it into the ground at the starting point and fix it, then start the upper box compartment, and drive the active rubber rotary wheel and the active concave rotary wheel on the side surface of the middle block to rotate in the same direction through the motor box, and pull the counting rope out from the side surface of the rope winding rod. After the counting rope passes through the limiting rope sleeve, the rope pressing rod and the deflection adjustment of the tail wheel, it passes through the traction sleeve close to the side of the middle block, and passes through the five staggered dial wheels in sequence. The traction sleeve at the end turns into the rope channel, and then stretches through the lower ring, the bottom rope sleeve, and falls into the L-shaped ropeway. Then, press the pin to make the arc baffle seal the gap, and continue to pull the counting rope to make it fall on the ground. When the counting rope accumulates a certain length, the auxiliary upper rotary wheel, the auxiliary lower rotary wheel and the carrier are started together to ensure that the length and speed of the counting rope flowing out are consistent, which can reduce the pulling force on the positioning rod;

[0022] S2. Along with the start of the carrier, the transmission machine is also started. The driving wheel connected to one end of the output shaft of the transmission machine is started together. The rack on the surface of the driving wheel drives the inner and outer toothed belts to rotate together. The driven gear located at the other end of the inner toothed belt can ensure the stability of rotation. When the paddle on the outer rack of the outer toothed belt encounters the drag plate, it will push the drag plate and the return plate to the inner side of the V-shaped track. In this process, since the crossbar on the top of the return plate limits the moving trajectory in the V-shaped track, one end will be moved first. The pull plate is disengaged from the top of the paddle plate by moving horizontally and then upwardly. After losing the thrust of the paddle plate, the pull plate is reset to block the hexagonal rod behind it under the thrust of the extrusion spring, and the side surface of the top plate of the falling drop rod falls into the groove of the grooved belt. With the rotation of the outer toothed belt, the hexagonal rod moves forward until it enters the docking ramp and is driven by the top plate to roll forward. When it reaches the platform ramp, one side of the hexagonal rod falls into the groove and slides down. At the end of the connecting ramp, it enters the falling channel through the gap of the upper ring.

[0023] S3. When the drop rod enters the docking ramp, the toothed plate on one side of the transmission belt will first mesh with the driving gear for transmission, and coaxially drive the lower gear on the other end to rotate through the linkage shaft. Here, the lower gear close to the driven gear side drives the side gear on the side surface to rotate, and the rotation of the side gear causes the synchronous shaft and connecting bevel gear of the same group to rotate, and the synchronous bevel gears at both ends of the middle connecting rod drive the connecting bevel gear and side gear of the other group to rotate, and then let the lower gear close to the active wheel side rotate, and the two groups of lower gears will cause the middle gear above the side surface to rotate. When the two groups of middle gears rotate, the elliptical disk at the other end of the central shaft will rotate. Due to the shape of the elliptical disk, The adjusting turntable is required to move upward, and the positioning wheel in the annular groove in the adjusting turntable makes the movable rod move upward in the upper fixed sleeve at one end of the top of the medium rod, and moves together with the tripod and the lower pressure rod during the upward movement. The linkage sleeve rod sleeved on the lower pressure rod pulls the slider sleeve at the bottom of the linkage block to lift it up, and presses the drop rod in the drop channel down to the ground. When the counting rope is in the same direction as the rectangular plate, the pressure plate on the side surface of the hexagonal rod will clamp the counting rope, or when the counting rope and the rectangular plate are staggered in direction, it will fall between the two plug cones, and there is a traction spring between the two plug cones to pull inward, which ensures the clamping force on the counting rope. In both cases, the counting rope will be fixed as the plug cone is inserted into the ground;

[0024] S4. The thrust spring located on the side surface of the movable rod will provide acceleration force to the falling slider sleeve and strengthen the hammering force. On the other hand, the feeding box located on the top of the measuring box can continuously provide falling rods, which can be placed in advance or added later from the feed port. The added falling rods fall along the upper slope to the lower slope and then pass through the feed port to the unloading ramp and are placed on the top of the conveyor belt. The telescopic rod and the limiting rope sleeve are pulled to perform reciprocating motion by the stepper motor to prevent the recovery counting rope from gathering at one place on the side surface of the rope winding rod.

[0025] The present invention provides an area measuring device for building construction, which has the following beneficial effects:

[0026] The area measuring device for construction can slowly release the counting rope through the cooperation of the rope retracting and releasing assembly and the rope winding frame, so as to avoid the vehicle stretching the rope during travel, which would cause the positioning rod at the starting point to be pulled up due to excessive force. On the other hand, the slackened rope can also facilitate the rod to be inserted into the ground and fixed, thereby increasing the rope stretching methods.

[0027] The area measuring device for construction use is linked with a feed box and a conveyor belt. When a lever located in the conveyor belt passes through a discharge channel, the lever can push open a drag plate and lower a drop rod. When the drop rod falls, the drag plate automatically resets under the action of a spring. The structures cooperate with each other to form an automatic loading and unloading structure.

[0028] The area measuring device for construction use can drive the various gear sets in the pressing assembly to rotate as the drop rod falls through the toothed plate on the side of the conveyor belt, thereby lifting the linkage assembly and the drop hammer assembly in turn and hammering and fixing the top of the drop rod that has entered the falling channel.

[0029] The area measuring device for construction uses the disc structure on the top of the drop rod and the grooves of other structures to guide displacement and increase the hammering surface. The hexagonal structure of the rod body makes it convenient to fix the rod body between the racks on the side surface of the conveyor belt, thereby improving the stability of transportation. The pressure plate and cone on the side of the rod body ensure that the bottom of the rod can be aligned and pressed down to fix the counting rope in any direction to prevent the rope from detaching.

[0030] The area measuring device for construction reduces the measuring pressure of workers through carrier operation, especially when the area is large. When a starting point is fixed, the shape of the measuring range can be adjusted arbitrarily, and during the driving process, the rope can be released and fixed at the same time, which increases the measuring efficiency.

[0069] A measuring method of an area measuring device for building construction comprises the following steps:

[0070] S1. First, move the vehicle 1 to the edge of the construction site. After determining the starting point, pull out the positioning rod 19 from the card plate 18 on the side surface of the measuring box 2, insert it into the ground at the starting point and fix it, then start 1601 in the upper box compartment 6, and drive the active rubber rotating wheel 1603 and the active concave rotating wheel 1604 on the side surface of the middle block 1602 to rotate in the same direction through the motor box 1601, and pull the counting rope 20 out from the side surface of the rope winding rod 1503. After the counting rope 20 passes through the limiting rope loop 1504, it is adjusted by the deflection of the rope pressing rod 1608 and the tail wheel 1607, and then passes through the side of the middle block 1602. The traction sleeve 1609 passes through the five staggered dial wheels 1610 in sequence, and then the traction sleeve 1609 at the end turns into the rope channel 17, and then stretches through the lower ring 1307, the bottom rope sleeve 1308, and falls into the L-shaped ropeway 1309. Then, the latch 1310 is pressed to make the arc baffle 1311 seal the gap, and the counting rope 20 is continued to be pulled to fall on the ground. When the counting rope 20 accumulates a certain length, the auxiliary upper rotating wheel 1605, the auxiliary lower rotating wheel 1606 and the carrier 1 are started together to ensure that the length and speed of the counting rope 20 flowing out are consistent, which can reduce the pulling force on the positioning rod 19;

[0071] S2. The transmission machine 9 is started along with the carrier 1. The driving wheel 801 connected to one end of the output shaft of the transmission machine 9 is started together. The rack on the surface of the driving wheel 801 drives the inner toothed belt 802 and the outer toothed belt 804 to rotate together. The driven gear 803 located at the other end of the inner toothed belt 802 can ensure the stability of the rotation. When the paddle 807 on the outer rack of the outer toothed belt 804 encounters the drag plate 3011, it pushes the drag plate 3011 and the return plate 3010 to the inner side of the V-shaped track 309. In this process, since the cross bar on the top of the return plate 3010 limits the moving trajectory in the V-shaped track 309, one end will be translated first, and then The sliding plate 3011 is moved upward, so that the sliding plate 3011 is separated from the top of the paddle plate 807. After losing the thrust of the paddle plate 807, the sliding plate 3011 is reset to block the hexagonal rod 402 behind under the thrust of the extrusion spring 3012, and the side surface of the top plate 401 of the falling drop rod 4 falls into the groove of the grooved belt 805, and moves forward with the rotation of the outer toothed belt 804 until the hexagonal rod 402 enters the docking ramp 1401, and is driven by the top plate 401 to roll forward. When it reaches the platform ramp 1402, one side of the hexagonal rod 402 falls into the groove and slides down, and at the end of the connecting ramp 1403, it enters the falling channel 1305 through the gap of the upper ring 1304;

[0072] S3. When the drop rod 4 enters the docking ramp 1401, the toothed plate 806 on one side of the transmission belt 8 will first mesh with the driving gear 1022 for transmission, and coaxially drive the lower gear 1017 at the other end to rotate through the linkage shaft 1018. Here, the lower gear 1017 close to the side of the driven gear 803 drives the side gear 1023 on the side surface to rotate, and the rotation of the side gear 1023 causes the synchronous shaft 1024 and the connecting bevel gear 1026 of the same group to rotate, and the rotation of the side gear 1023 causes the synchronous shaft 1024 and the connecting bevel gear 1026 of the same group to rotate. The synchronous bevel gears 1027 at both ends of the central connecting rod 1028 drive the other group of connecting bevel gears 1026 and the side rotating gears 1023 to rotate, and then the lower rotating gears 1017 close to the side of the active rotating wheel 801 rotate, and the two groups of lower rotating gears 1017 will make the central rotating gears 1016 above the side surface rotate. When the two groups of central rotating gears 1016 rotate, the elliptical disk 1004 at the other end of the central shaft 1003 will rotate. Due to the shape of the elliptical disk 1004, The adjusting turntable 1005 is lifted up, and the positioning wheel 1007 in the annular groove 1006 in the adjusting turntable 1005 makes the movable rod 1009 move up in the upper fixed sleeve 1010 at one end of the top of the medium rod 1002, and during the upward movement, the tripod 1013 and the lower pressure rod 1015 move together, and the linkage sleeve rod 1102 sleeved on the lower pressure rod 1015 pulls the slider sleeve 1202 at the bottom of the linkage block 1103 to lift up, so that the slider sleeve 1202 at the bottom of the falling channel is lifted up. The drop rod 4 in 1305 is pressed down to the ground. When the counting rope 20 is in the same direction as the rectangular plate 404, the pressing plate 403 on the side surface of the hexagonal rod 402 will clamp the counting rope 20. Or when the counting rope 20 and the rectangular plate 404 are in the same direction, they will fall between the two inserting cones 406. There is a traction spring 407 between the two inserting cones 406 to pull inwards, ensuring the clamping force on the counting rope 20. In both cases, the counting rope 20 will be fixed as the inserting cone 406 is inserted into the ground.

[0073] S4. The thrust spring 1014 located on the side surface of the movable rod 1009 will provide acceleration force to the falling slider sleeve 1202, thereby increasing the hammering force. On the other hand, the feed box 3 located on the top of the measuring box 2 can continuously provide drop rods 4, which can be placed in advance or added later from the feed port 303. The added drop rods 4 fall along the inclined surface of the upper slope 304 into the lower slope 305 and then pass through the feed port 303 to the unloading ramp 307, and are placed on the top of the conveyor belt 8. The telescopic rod 1505 and the limiting rope loop 1504 are pulled to perform reciprocating motion by the stepper motor 1506 to prevent the recovery counting rope 20 from gathering at one place on the side surface of the rope winding rod 1503.

[0074] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

10. The measuring method of the area measuring device for building construction according to claim 9, comprising the following steps: S1. First, the carrier (1) is moved to the edge of the construction site. After the starting point is determined, the positioning rod (19) is pulled out from the card plate (18) on the side surface of the measuring box (2), and the positioning rod (19) is inserted and fixed to the ground at the starting point. Then, 1601 in the upper box compartment (6) is started, and the active rubber rotating wheel (1603) and the active concave rotating wheel (1604) on the side surface of the middle block (1602) are driven by the motor box (1601) to rotate in the same direction, and the counting rope (20) is pulled out from the side surface of the rope winding rod (1503). After the counting rope (20) passes through the limiting rope loop (1504), it is adjusted by the rope pressing rod (1608) and the tail wheel (1607), and then passes through the side of the middle block (1602) close to the middle block (1602). The traction sleeve (1609) passes through the five staggered dial wheels (1610) in an interlaced manner, and then the traction sleeve (1609) at the end is turned into the rope channel (17), and then stretched through the lower ring (1307), the bottom rope sleeve (1308), and falls into the L-shaped rope path (1309). Then, the latch (1310) is pressed to make the arc baffle (1311) seal the gap, and the counting rope (20) is continued to be pulled to fall on the ground. When the counting rope (20) accumulates to a certain length, the auxiliary upper rotating wheel (1605), the auxiliary lower rotating wheel (1606) and the carrier (1) are started together to ensure that the length and speed of the counting rope (20) flowing out are consistent, which can reduce the pulling force on the positioning rod (19); S2. Along with the vehicle (1), the transmission machine (9) is also started. The driving wheel (801) connected to one end of the output shaft of the transmission machine (9) is started together. The rack on the surface of the driving wheel (801) drives the inner toothed belt (802) and the outer toothed belt (804) to rotate together. The driven gear (803) located at the other end of the inner toothed belt (802) can ensure the stability of the rotation. When the paddle (807) on the outer rack of the outer toothed belt (804) encounters the drag plate (3011), it pushes the drag plate (3011) and the return plate (3010) to move closer to the inside of the V-shaped track (309). During this process, since the cross bar on the top of the return plate (3010) limits the moving trajectory in the V-shaped track (309), one end will be translated first, and then The sliding plate (3011) moves upward, so that the sliding plate (3011) is separated from the top of the shifting plate (807). After losing the thrust of the shifting plate (807), the sliding plate (3011) is reset to block the hexagonal rod (402) behind it under the thrust of the extrusion spring (3012), and the side surface of the top plate (401) of the falling drop rod (4) falls into the groove of the grooved belt (805), and moves forward with the rotation of the outer toothed belt (804) until the hexagonal rod (402) enters the docking ramp (1401), and is driven by the top plate (401) to roll forward. When reaching the platform ramp (1402), one side of the hexagonal rod (402) falls into the groove and slides down, and at the end of the connecting ramp (1403), it enters the falling channel (1305) through the gap of the upper ring (1304); S3. When the drop rod (4) enters the docking ramp (1401), the toothed plate (806) on one side of the transmission belt (8) will first mesh with the driving gear (1022) to drive the lower gear (1017) on the other end to rotate coaxially through the linkage shaft (1018). Here, the lower gear (1017) close to the side of the driven gear (803) drives the side gear (1023) on the side surface to rotate, and the rotation of the side gear (1023) causes the synchronous shaft (1024) and the connecting bevel gear (1026) of the same group to rotate. The synchronous bevel gears (1027) at both ends of the central connecting rod (1028) drive the other set of connecting bevel gears (1026) and the side rotating gears (1023) to rotate, and then the lower rotating gears (1017) close to the side of the active rotating wheel (801) rotate, and the two sets of lower rotating gears (1017) will cause the central rotating gears (1016) above the side surface to rotate. When the two sets of central rotating gears (1016) rotate, the elliptical disk (1004) at the other end of the central shaft (1003) will rotate. Due to the shape of the elliptical disk (1004), the adjustment The turntable (1005) moves upward, and the positioning wheel (1007) in the annular groove (1006) of the adjusting turntable (1005) causes the movable rod (1009) to move upward in the upper fixed sleeve (1010) at one end of the top of the medium rod (1002). During the upward movement, the tripod (1013) and the lower pressure rod (1015) move together. The linkage sleeve rod (1102) sleeved on the lower pressure rod (1015) pulls the slider sleeve (1202) at the bottom of the linkage block (1103) to be lifted high, so that the slider sleeve (1202) located at the falling channel (1303) is lifted upward. 05) is pressed down to the ground, when the counting rope (20) and the rectangular plate (404) are in the same direction, the pressing plate (403) on the side surface of the hexagonal rod (402) will clamp the counting rope (20), or when the counting rope (20) and the rectangular plate (404) are in the same direction, they will fall between the two insert cones (406), and there is a traction spring (407) between the two insert cones (406) to pull inwards, thereby ensuring the clamping force on the counting rope (20). In both cases, the counting rope (20) will be fixed as the insert cone (406) is inserted into the ground; S4. The thrust spring (1014) located on the side surface of the movable rod (1009) provides an acceleration force to the falling slider sleeve (1202) to strengthen the hammering force. On the other hand, the feeding box (3) located on the top of the measuring box (2) can continuously provide the falling rod (4), which can be placed in advance or added later from the feed port (303). The added falling rod (4) falls into the lower slope (305) along the inclined surface of the upper slope (304) and then passes through the feed port (303) to the unloading ramp (307), and is placed on the top of the conveyor belt (8). The telescopic rod (1505) and the limiting rope sleeve (1504) are pulled by the stepping motor (1506) to perform reciprocating motion, thereby preventing the recovery counting rope (20) from gathering at a place on the side surface of the rope winding rod (1503).
