Description

Technical Field

[0001] The utility model relates to the technical field of precise measurement of construction site materials, and particularly relates to a precise measurement device for construction site materials based on BIM. Background Technique

[0002] The precise measurement device for construction site materials based on building information model is an intelligent system that combines BIM technology and Internet of Things technology, and is used to achieve precise measurement and management of materials at the construction site. For example, in mortar preparation, a precise measurement device for materials is usually used to weigh the proportioned mortar raw materials to reduce the waste of mortar preparation and optimize resource allocation.

[0003] After retrieval, the Chinese patent "High-efficiency preparation device for interfacial mortar" with the authorization announcement number "CN215472087U" realizes the weighing of the proportioned mortar raw materials in and out through a weight sensor, a display screen, a hook and a material bag, which is beneficial to more accurate proportioning of interfacial mortar.

[0004] In the above application, after the proportioned mortar raw materials are loaded into the material bag and weighed, and then the proportioned raw materials in the material bag are poured into the mixing barrel, this method makes it too inconvenient to pour the proportioned raw materials in the material bag into the mixing barrel.

[0005] Therefore, a precise measurement device for construction site materials based on BIM is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a precise measurement device for construction site materials based on BIM to solve the above problems, and improves the problem that it is too inconvenient to pour the proportioned raw materials in the material bag into the mixing barrel.

[0007] The present utility model achieves the above object through the following technical solutions. A precise metering device for construction site materials based on BIM includes: a mixing barrel, with a meter fixedly connected to the top of the mixing barrel; a weighing mechanism disposed at the bottom of the meter. Among them, the weighing mechanism includes a weighing cylinder fixedly connected to the bottom of the meter. An inlet frame is fixedly connected to the upper end of the surface of the weighing cylinder. A sealing cover is hinged to the lower end of the surface of the weighing cylinder. One end of the sealing cover is fixedly connected to a dial. An iron rod is slidably connected to the upper end of the inner wall of the dial. The surface of the iron rod is clamped to the lower end of the inner wall of the weighing cylinder. One end of the iron rod is fixedly connected to a spring, and the other end of the spring is fixedly connected to one end of the inner wall of the dial. Through the inlet frame and the weighing cylinder, it is convenient to pour the mortar proportioning raw materials into the weighing cylinder. Compared with the existing method of pouring the mortar proportioning raw materials into a material bag, where it is necessary to open the opening of the material bag, resulting in inconvenient operation, this method reduces the inconvenience of weighing the mortar proportioning raw materials. Through the sealing cover and the dial, the opening at the bottom end of the weighing cylinder is opened. Compared with the existing method of pushing the material bag to pour the weighed mortar proportioning raw materials in the material bag into the mixing barrel, this method is more convenient and labor-saving for pouring the mortar proportioning raw materials. Through the spring and the iron rod, the top end of the sealing cover stably abuts against the bottom end of the weighing cylinder, ensuring stable weighing of the mortar proportioning raw materials in the weighing cylinder.

[0008] Preferably, a rotating rod is rotatably connected to the inner wall of the weighing cylinder. A regulating frame is fixedly connected to the lower end of the surface of the rotating rod. One side of the regulating frame contacts the inner wall of the weighing cylinder. The top end of the rotating rod is fixedly connected to a first servo motor. Through the first servo motor, the regulating frame and the rotating rod, the mortar proportioning raw materials in the weighing cylinder are scraped off, enabling the raw materials in the weighing cylinder to quickly fall into the mixing barrel, preventing the mortar proportioning raw materials from remaining in the weighing cylinder and reducing waste of resources.

[0009] Preferably, two stoppers are fixedly connected to the lower end of the surface of the weighing cylinder.

[0010] Preferably, a driven block is fixedly connected to the surface of the sealing cover. The bottom of the driven block contacts the top of one of the stoppers. Through the stopper and the driven block, the flipping angle of the sealing cover is restricted, facilitating the precise insertion of the iron rod into the lower end of the inner wall of the weighing cylinder.

[0011] Preferably, the lower end of the surface of the weighing cylinder is funnel-shaped.

[0012] Preferably, a magnetic attracting ring is fixedly connected to the upper end of the inner wall of the dial. The surface of the magnetic attracting ring magnetically attracts the surface of the iron rod. Through the magnetic attracting ring, it is ensured that the iron rod is stably clamped to the lower end of the inner wall of the weighing cylinder, thereby ensuring the stable sealing of the bottom end of the weighing cylinder by the sealing cover.

[0013] Preferably, a protective frame is fixedly connected to the bottom of the meter, and the top end of the servo motor is fixedly connected to the inner wall of the protective frame. Through the protective frame, the support and protection of the servo motor are realized, and impurities are prevented from adhering to the surface of the servo motor.

[0014] Preferably, the bottom of the feeding frame forms an angle with the horizontal plane, and both the feeding frame and the weighing cylinder are made of stainless steel members.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. Through the feeding frame and the weighing cylinder, it is convenient to pour the mortar proportioning raw materials into the weighing cylinder. Compared with the existing method of pouring the mortar proportioning raw materials into a material bag, which requires opening the opening of the material bag, resulting in inconvenient operation, this method reduces the inconvenience of weighing the mortar proportioning raw materials. Through the sealing cover and the dial, the opening at the bottom end of the weighing cylinder is opened. Compared with the existing method of pushing the material bag to pour the weighed mortar proportioning raw materials in the material bag into the mixing barrel, this method is more convenient and labor-saving for pouring the mortar proportioning raw materials. Through the spring and the iron rod, the top end of the sealing cover is stably abutted against the bottom end of the weighing cylinder, ensuring stable weighing of the mortar proportioning raw materials in the weighing cylinder;

[0017] 2. Through the first servo motor, the adjusting frame and the rotating rod, the mortar proportioning raw materials in the weighing cylinder are scraped off, so that the raw materials in the weighing cylinder quickly fall into the mixing barrel, preventing the mortar proportioning raw materials from staying in the weighing cylinder and reducing the waste of resources.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] During specific implementation: As Figures 1-4 shown, a precise metering device for construction site materials based on BIM includes: a mixing barrel 1, and a meter 2 is fixedly connected to the top of the mixing barrel 1; a weighing mechanism 3, and the weighing mechanism 3 is arranged at the bottom of the meter 2; wherein, the weighing mechanism 3 includes a weighing cylinder 31 fixedly connected to the bottom of the meter 2, a feeding frame 32 is fixedly connected to the upper end of the surface of the weighing cylinder 31, a sealing cover 33 is hinged to the lower end of the surface of the weighing cylinder 31, a dial 34 is fixedly connected to one end of the sealing cover 33, an iron rod 35 is slidably connected to the upper end of the inner wall of the dial 34, the surface of the iron rod 35 is clamped to the lower end of the inner wall of the weighing cylinder 31, a spring 36 is fixedly connected to one end of the iron rod 35, and the other end of the spring 36 is fixedly connected to one end of the inner wall of the dial 34. The lower end of the surface of the weighing cylinder 31 is funnel-shaped, and a magnetic attracting ring is fixedly connected to the upper end of the inner wall of the dial 34, and the surface of the magnetic attracting ring is magnetically attracted to the surface of the iron rod 35.

[0025] During the preparation of mortar, manually turn on the meter 2 and operate the numerical control display screen on the meter 2 to make the meter 2 tare the weighing cylinder 31. Pour raw materials such as cement, sand, and interface agent into the weighing cylinder 31 through the feeding frame 32. At this time, the meter 2 weighs the raw materials in the weighing cylinder 31, and the weighed data is displayed on the numerical control display screen of the meter 2 for the staff to intuitively understand the specific weight of the raw materials. Since the meter 2 is connected to the wireless communication technology, the data of the raw materials weighed in the weighing cylinder 31 by the meter 2 is stored in the cloud or the local server to ensure the security and accessibility of the data. When the corresponding amount is exceeded, part of the raw materials in the weighing cylinder 31 is removed. After the raw materials in the weighing cylinder 31 reach the appropriate amount, at this time, pull the iron rod 35 to make the iron rod 35 away from the lower end of the inner wall of the weighing cylinder 31, push the dial 34, and make the dial 34 drive the sealing cover 33 to turn over, so that the bottom opening of the weighing cylinder 31 is opened, and the raw materials fall into the mixing barrel 1. At this time, after adding a certain amount of water into the mixing barrel 1, the mixing barrel 1 stirs the raw materials to form mortar. After the mortar is prepared, by opening the discharge pipe at the bottom of the mixing barrel 1, the mortar is discharged for building construction.

[0026] As Figure 3As shown in the figure, a rotating rod 39 is rotatably connected to the inner wall of the weighing cylinder 31. A lower end of the surface of the rotating rod 39 is fixedly connected with an adjusting frame 310. One side of the adjusting frame 310 contacts the inner wall of the weighing cylinder 31. A top end of the rotating rod 39 is fixedly connected with a first servo motor 311. A bottom of the meter 2 is fixedly connected with a protective frame 312. A top end of the servo motor 311 is fixedly connected to the inner wall of the protective frame 312.

[0027] Manually turn on the servo motor 311. The output shaft of the servo motor 311 rotates to drive the rotating rod 39 to rotate. The rotating rod 39 rotates to drive the adjusting frame 310 to rotate. The rotating adjusting frame 310 stirs the raw materials in the weighing cylinder 31, enhancing the fluidity of the raw materials and quickly discharging them from the weighing cylinder 31. After the raw materials are discharged, manually turn off the servo motor 311.

[0028] As Figure 4 shown, two stoppers 37 are fixedly connected to a lower end of the surface of the weighing cylinder 31. A driven block 38 is fixedly connected to the surface of the sealing cover 33. A bottom of the driven block 38 contacts a top of one of the stoppers 37.

[0029] As Figure 3 shown, a bottom of the feeding frame 32 forms an angle with the horizontal plane. Both the feeding frame 32 and the weighing cylinder 31 are made of stainless steel components. Both the rotating rod 39 and the adjusting frame 310 are made of stainless steel components.

[0030] When the present utility model is in use, manually turn on the meter 2 and operate the numerical control display screen on the meter 2 to tare the weighing cylinder 31 by the meter 2. Pour raw materials such as cement, sand, and interfacial agent into the weighing cylinder 31 through the feeding frame 32. At this time, the meter 2 weighs the raw materials in the weighing cylinder 31, and the weighed data is displayed on the numerical control display screen of the meter 2 for the staff to directly understand the specific weight of the raw materials. When the corresponding amount is exceeded, dig out some of the raw materials in the weighing cylinder 31. When the raw materials in the weighing cylinder 31 reach the appropriate amount, pull the iron rod 35 at this time to make the iron rod 35 away from the lower end of the inner wall of the weighing cylinder 31. Push the dial 34 to drive the sealing cover 33 to flip, so that the bottom of the driven block 38 abuts against the top of one of the stoppers 37. Stop pushing the dial 34 to open the bottom opening of the weighing cylinder 31, and the raw materials fall into the mixing barrel 1. Manually turn on the servo motor 311. The output shaft of the servo motor 311 rotates to drive the rotating rod 39 to rotate. The rotating rod 39 rotates to drive the adjusting frame 310 to rotate. The rotating adjusting frame 310 stirs the raw materials in the weighing cylinder 31, enhancing the fluidity of the raw materials and quickly discharging them from the weighing cylinder 31. After the raw materials are discharged, manually turn off the servo motor 311.

[0031] It should be noted that in the above description, the mixing barrel 1, the meter 2, the servo motor 311, the magnetic ring, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply for the meter 2 and the servo motor 311 can be an internal power supply or a mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0032] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
