Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping devices, in particular to a surveying and mapping device for building construction based on BIM. Background Art

[0002] Surveying and mapping instruments, in simple terms, are instruments and devices designed and manufactured for surveying and mapping operations for data collection, processing, and output. They are instruments for various types of orientation, distance, angle, height, mapping, and photogrammetry required for surveying work during the planning, design, construction, and management stages of engineering construction.

[0003] According to a BIM-based surveying and mapping device for building construction disclosed in Chinese patent publication number CN216590882U, the utility model discloses a BIM-based surveying and mapping device for building construction, including a base, a telescopic rod is arranged in the middle of the base, a rotating shaft is arranged in the inner cavity of the telescopic rod, a sliding cylinder is arranged at the bottom of the telescopic rod, a protective plate is fixedly connected to the top of the telescopic rod, a mounting groove is arranged in the inner cavity of the protective plate, a balancing instrument is fixedly connected to the top of the mounting groove, a supporting leg is arranged in the inner cavity of the base, an adjusting shaft is arranged on the top of the supporting leg, and the telescopic plate can be stretched outward by the cooperation of the balancing frame and the fixed shaft, so as to meet the fitting use of various equipment, and the height of the suction cup is adjusted by rotating the bearing. When the supporting plate is subjected to force, the rubber column and the buffer spring cooperate to produce a rebound effect, so that the measurement work can be better accurately measured, and the generation of the BIM model is better guaranteed.

[0004] According to the above patent, when installing the surveying and mapping device on the ground, it is necessary to first fix the surveying and mapping device by cooperating with the supporting legs and the adjusting shaft, and then stretch the telescopic rod by cooperating with the rotating shaft and the sliding cylinder to adjust the inclination angle of the supporting legs to achieve the effect of leveling the surveying and mapping device. This adjustment method has too many steps, which affects the installation efficiency of the surveying and mapping device.

[0005] However, three-dimensional models can be quickly generated through BIM3D visualization technology, which requires surveying and mapping devices to collect construction scene data from multiple angles. Therefore, the surveying and mapping device needs to change the data collection scene according to use, and the surveying and mapping device needs to be re-leveled every time it is changed. Too many leveling steps for the surveying and mapping device will greatly affect the information collection efficiency of the surveying and mapping device. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a BIM-based surveying and mapping device for building construction, so as to solve the technical problems mentioned in the above background technology.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0008] A BIM-based surveying and mapping device for building construction comprises a base and a surveying and mapping instrument body, wherein the four bottom corners of the base are hinged with support legs, a ball groove is provided in the middle of the base, an adjusting ball is sleeved in the ball groove, the top of the adjusting ball is fixedly connected to the surveying and mapping instrument body through a support rod, the top of the surveying and mapping instrument body is fixedly connected to a BIM processor, and the bottom of the adjusting ball is fixedly connected to a counterweight ball through a connecting rod.

[0009] Furthermore, a plurality of balls are evenly distributed on the inner wall of the adjusting ball, and a side of the balls away from the inner wall of the ball groove contacts the outer wall of the adjusting ball.

[0010] Furthermore, a groove for accommodating the supporting leg is formed on the outer side wall of the counterweight ball, and a protrusion for clamping the supporting leg is formed on the opening of the inner side wall of the groove.

[0011] Furthermore, sealing rings are fixedly connected to the top and bottom openings of the ball groove, and the inner wall of the sealing ring fits with the outer wall of the adjusting ball.

[0012] Furthermore, a main rod and a secondary rod are provided between two adjacent supporting legs, the ends of the main rod and the secondary rod are hinged, and the ends of the main rod and the secondary rod away from the hinge point are respectively hinged to the corresponding supporting legs.

[0013] Furthermore, the weight of the counterweight ball is greater than that of the surveying instrument body, so that the center of gravity of the adjustment ball is located below the center of the ball slot.

[0014] In summary, the present invention includes at least one of the following beneficial technical effects:

[0015] 1. The BIM-based surveying and mapping device for building construction, through the provided adjustment ball and counterweight ball, can make the counterweight ball rotate in the ball groove with the adjustment ball through the connecting rod under the action of gravity when the base is tilted, so that the surveying and mapping device body always keeps a horizontal state, so that the surveying and mapping device for building construction can be directly installed and used in any scene, eliminating the step of leveling the surveying and mapping device body, thereby improving the efficiency of surveying and mapping data collection, making the acquisition of BIM point information more accurate, and thus the three-dimensional model generated by the surveying and mapping device collecting information has higher accuracy;

[0016] 2. This BIM-based surveying and mapping device for construction can reduce friction by using the rolling contact of the balls arranged in the ball grooves, thereby reducing the wear caused by the rotation of the adjusting ball and making the leveling effect of the counterweight ball more sensitive. Sealing rings are arranged at the top and bottom openings of the ball grooves, and the sealing rings can be used to intercept dust particles outside the ball grooves, which can effectively prevent dust particles from entering the ball grooves and causing damage to the adjusting balls and the balls.

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Example:

[0026] Reference Figure 1 - Figure 5The utility model discloses a BIM-based surveying and mapping device for construction, comprising a base 1 and a surveying and mapping instrument body 2, wherein the four bottom corners of the base 1 are hinged with support legs 3, a ball groove 4 is provided in the middle of the base 1, an adjusting ball 5 is sleeved in the ball groove 4, the top of the adjusting ball 5 is fixedly connected to the surveying and mapping instrument body 2 through a supporting rod 6, the top of the surveying and mapping instrument body 2 is fixedly connected with a BIM processor 15, and the bottom of the adjusting ball 5 is fixedly connected with a counterweight ball 8 through a connecting rod 7.

[0027] In this embodiment, when in use, the support legs 3 at the bottom of the base 1 are opened, and then the support legs 3 are used to provide support for the base 1 so that the base 1 is stably placed on the ground. Then, the surveying instrument body 2 is started to collect data on the construction site, and finally the collected data is transmitted to the BIM processor 15 to generate a stereoscopic three-dimensional model to complete the surveying and mapping of the construction.

[0028] When the ground at the construction site is uneven, because the length of the support leg 3 cannot be adjusted, the point where the support leg 3 contacts the ground cannot be kept on the same horizontal plane, which will cause the base 1 to tilt. When the base 1 tilts, the counterweight ball 8 located at the bottom of the adjustment ball 5 will always remain directly below the adjustment ball 5 under the action of gravity. Therefore, the counterweight ball 8 rotates in the ball slot 4 with the adjustment ball 5 through the connecting rod 7, and then the adjustment ball 5 adjusts the position with the surveying instrument body 2 through the support rod 6, so as to achieve automatic correction of the surveying instrument body 2, so that the surveying instrument body 2 can always be kept in a horizontal state, thereby making the BIM point data collection more accurate and the three-dimensional model generated by the BIM processor 15 more accurate. By making the surveying instrument body 2 automatically leveled, the surveying and mapping device for construction can be directly installed and used in any scene, eliminating the step of leveling the surveying and mapping instrument body 2, thereby improving the efficiency of surveying and mapping data collection and increasing the speed of generating BIM models.

[0029] In a further preferred embodiment of the present invention, Figure 3 As shown, a plurality of balls 9 are evenly distributed on the inner wall of the adjusting ball 5 , and the side of the balls 9 away from the inner wall of the ball groove 4 contacts the outer wall of the adjusting ball 5 .

[0030] In this embodiment, because the adjusting ball 5 will contact the inner wall of the ball groove 4 when it rotates driven by the counterweight ball 8, the friction between the adjusting ball 5 and the inner wall of the ball groove 4 will cause damage, and the large-area contact will also increase the friction between the adjusting ball 5 and the ball groove 4, affecting the leveling effect of the counterweight ball 8. Therefore, a ball 9 is provided on the inner wall of the ball groove 4, and the ball 9 is in contact with the adjusting ball 5. When the adjusting ball 5 rotates, the rolling contact of the ball 9 is used to reduce the friction, thereby reducing the wear of the adjusting ball 5 when it rotates, and can also make the leveling effect of the counterweight ball 8 more sensitive.

[0031] In a further preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, a groove 10 for accommodating the support leg 3 is formed on the outer wall of the counterweight ball 8 , and a protrusion 11 for clamping the support leg 3 is formed at the opening of the inner wall of the groove 10 .

[0032] In this embodiment, by providing a groove 10 for accommodating the support leg 3 on the outer side wall of the counterweight ball 8, the support leg 3 can be placed in the groove 10 when storing the surveying and mapping device for construction, thereby preventing the support leg from being loose when storing the surveying and mapping device for construction, thereby increasing the difficulty of storage. By providing a protrusion 11 at the opening of the inner side wall of the groove 10, the support leg 3 can be clamped by the protrusion 11, thereby preventing the support leg 3 from falling out of the groove 10 due to bumps during transportation, thereby achieving a better storage effect of the surveying and mapping device for construction.

[0033] In a further preferred embodiment of the present invention, Figure 3 As shown, a sealing ring 12 is fixedly connected to the top and bottom openings of the ball groove 4 , and the inner wall of the sealing ring 12 fits with the outer wall of the adjusting ball 5 .

[0034] In this embodiment, since there is a gap between the adjusting ball 5 and the ball groove 4, dust particles and the like may enter the gap, causing the adjusting ball 5 to rub against the dust particles when rotating, resulting in scratches on the surface of the ball 9 or the adjusting ball 5, thereby affecting the smoothness of the surface of the ball 9 and the adjusting ball 5 and reducing the rotation sensitivity of the adjusting ball 5. Therefore, a sealing ring 12 is connected to the top opening and the bottom opening of the ball groove 4, and the sealing ring 12 contacts the outer wall of the adjusting ball 5. When the adjusting ball 5 rotates, the sealing ring 12 can be used to intercept dust particles outside the ball groove 4, thereby effectively preventing dust particles from entering the ball groove 4 and causing damage to the adjusting ball 5 and the ball 9.

[0035] In a further preferred embodiment of the present invention, Figure 1 As shown, a main rod 13 and a secondary rod 14 are provided between two adjacent supporting legs 3 , the ends of the main rod 13 and the secondary rod 14 are hinged, and the ends of the main rod 13 and the secondary rod 14 away from the hinge point are hinged to the corresponding supporting legs 3 respectively.

[0036] In this embodiment, by providing the main rod 13 and the auxiliary rod 14, a pulling force can be applied to the support leg 3 when the support leg 3 is opened, which can share the pressure generated by the support leg 3 being pressed down by the weight of the base 1 and the surveying instrument body 2 and other components, thereby reducing the pressure on the hinge point between the support leg 3 and the base 1, and can effectively enhance the pressure-bearing capacity of the support leg 3, making the support of the support leg 3 more stable.

[0037] In a further preferred embodiment of the present invention, Figure 3 As shown, the weight of the counterweight ball 8 is greater than that of the surveying instrument body 2 , so that the center of gravity of the adjustment ball 5 is located below the center of the ball slot 4 .

[0038] In this embodiment, by making the weight of the counterweight ball 8 greater than the surveying instrument body 2 so that the center of gravity of the adjustment ball 5 is located below the center of the ball groove 4, when the base 1 is tilted, the adjustment ball 5 can rotate in the ball groove 4 under the action of the center of gravity, thereby keeping the surveying instrument body 2 always level.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
