Description

Technical Field

[0001] The utility model relates to the technical field of cement processing, in particular to cement quality detection equipment used in construction projects. Background Art

[0002] Cement is a powdered, hydraulic, inorganic binder that solidifies and hardens when mixed with water. It's not typically used alone, but rather combined with sand or gravel to form mortar or concrete. Cement's main ingredients are lime or calcium silicate, and once hardened, it resists erosion by fresh or salt water. As an important binder, it's widely used in civil engineering, water conservancy projects, and national defense projects.

[0003] A search of a Chinese patent with publication number CN219266294U disclosed a cement quality detection device.

[0004] The utility model includes a base plate, a sliding groove is provided on the top surface of the base plate, a fixed plate is fixedly installed on one side of the base plate, a mixing box is fixedly installed on the top surface of the fixed plate, a fixed groove is provided on one side of the fixed plate, and a connecting pipe is fixedly sleeved on the inner circular wall surface of the fixing groove, and one end of the connecting pipe extends to the interior of the mixing box; a detection component, the detection component is arranged on the top surface of the base plate, and is used to detect the expansion volume of the cement. The powdered cement can be fully stirred by the mixing box under the action of the driving motor, and then injected into the first fixed barrel and the second fixed barrel through the connecting pipe, thereby assisting the detection component to detect the cement. By arranging a transparent plate, it is convenient for the staff to intuitively observe the volume of the cement after expansion, and thus statistics are made by pointing to the position of the block on the scale, thereby improving the flexibility of the detection component.

[0005] However, this patent still has the following problems: although the device can directly fill cement into two fixed barrels to achieve rapid cement injection, since the cement injection position is fixed, it will make it difficult to evenly distribute the cement in the fixed barrel, which will cause bubbles to easily appear in the cement slurry. If the cement slurry contains more bubbles, it will increase the buoyancy of the blocking plate, resulting in a higher measurement result, making it difficult to achieve accurate measurement, and the practicality is poor.

DETAILED DESCRIPTION

[0031] See also Figure 1-Figure 7 , a cement quality detection device for construction projects, comprising a base 1, a movable mechanism 2 and a material discharge mechanism 4 are provided on the top of the base 1, a holding mechanism 3 is provided on the surface of the movable mechanism 2, and a mixing mechanism 5 is provided on the surface of the material discharge mechanism 4;

[0032] The movable mechanism 2 allows the cement slurry to vibrate and can move the internal components of the holding mechanism 3. The holding mechanism 3 is used to hold the cement slurry. The feeding mechanism 4 allows the cement slurry to be evenly distributed during the feeding process. The mixing mechanism 5 is used to mix the cement slurry and perform feeding processing.

[0033] The movable mechanism 2 includes a drive housing 201, a vibration motor 203 and a first U-shaped plate 204 are fixed to the bottom of the drive housing 201, a shock absorber 205 is fixed to the bottom of the first U-shaped plate 204, and the bottom of the shock absorber 205 is fixedly connected to the surface of the base 1. An adjustment structure is installed inside the drive housing 201;

[0034] During the filling process of cement slurry, it can be filled in sections. After each certain amount of cement is filled, the shock absorber 205 is started so that the drive shell 201 can drive the first U-shaped plate 204 to vibrate, so that the cement slurry can also obtain a vibration effect, so that the air inside the cement slurry can be quickly discharged, and the shock absorber 205 can buffer and reduce the vibration transmitted to the base 1. After that, the cement filling operation is performed again and the vibration motor 203 is started again, so that there are fewer bubbles inside the cement slurry after filling, thereby improving the accuracy and reliability of the measurement results. The adjustment structure is used to adjust the position of the internal components of the containing mechanism 3.

[0035] The containing mechanism 3 includes a first containing shell 301 and a second containing shell 302. A floating plate 303 is slidably connected inside the first containing shell 301 and the second containing shell 302. A transparent observation window 304 is embedded and fixed on the surface of the first containing shell 301 and the second containing shell 302.

[0036] The first containing shell 301 and the second containing shell 302 can be moved closer to or further away from each other through an adjustment structure. After they are brought closer together, cement slurry can be filled inside the first containing shell 301 and the second containing shell 302 through the mixing mechanism 5 and the discharge mechanism 4. After the cement slurry is filled, the floating plate 303 is placed inside the first containing shell 301 and the second containing shell 302 so that it is located on top of the cement slurry. The height position of the floating plate 303 is then observed and recorded through the transparent observation window 304. The height of the floating plate 303 is then observed again after the cement solidifies, thereby realizing the detection operation of the cement expansion coefficient.

[0037] The unloading mechanism 4 includes a support frame 401 and a mounting frame 406. A lifting structure is installed on the surface of the support frame 401. A reciprocating screw rod 408 is rotatably connected to the surface of the mounting frame 406. A first motor 407 is fixed to the surface of the mounting frame 406. The output shaft of the first motor 407 is fixedly connected to one end of the reciprocating screw rod 408. A moving block 409 is threadedly connected to the surface of the reciprocating screw rod 408. A telescopic rod 410 is fixed to the surface of the moving block 409. A nozzle 411 is fixed to one end of the telescopic rod 410.

[0038] The lifting structure can drive the mounting frame 406 to adjust the height, thereby adjusting the height position of the nozzle 411, and the telescopic rod 410 can be extended and retracted to raise the position of the nozzle 411 so that it does not block the placement of the floating plate 303. When filling cement slurry into the first containing shell 301 and the second containing shell 302, the first motor 407 is started to rotate the reciprocating screw 408, so that the moving block 409 can move back and forth on the surface of the reciprocating screw 408, thereby changing the position of the nozzle 411, and then the cement slurry is transported to the inside of the nozzle 411 through the mixing mechanism 5, so that the cement slurry can be evenly covered inside the first containing shell 301 and the second containing shell 302, thereby reducing the occurrence of bubbles and improving the subsequent detection accuracy.

[0039] Furthermore, the mixing mechanism 5 includes a mixing box 501, which is fixed above the surface of the support frame 401. A second motor 502 is fixed to the top of the mixing box 501. The output shaft of the second motor 502 passes through the interior of the mixing box 501 and is fixed with a stirring rod 503. The bottom of the mixing box 501 is connected to a solenoid valve 504. The surface of the solenoid valve 504 is connected to a bellows 505. The bottom of the bellows 505 is connected to the top of the nozzle 411. A feeding port 506 is opened on the top of the mixing box 501.

[0040] Cement slurry can be added to the mixing box 501 through the feeding port 506. When the second motor 502 is started, it can drive the stirring rod 503 to mix the cement slurry. When the solenoid valve 504 is opened, the cement slurry can be transported to the inside of the nozzle 411 through the bellows 505, and then sprayed out from the nozzle 411 toward the inside of the first containing shell 301 and the second containing shell 302.

[0041] Furthermore, the internal adjustment structure of the movable mechanism 2 includes two bidirectional screw rods 206, which are rotatably connected to the inner wall of the drive shell 201. Two first movable blocks 207 are threadedly connected to the surface of the bidirectional screw rod 206. A plurality of slide grooves 202 are provided on the surface of the drive shell 201. The first movable block 207 is slidably connected to the surface of the slide groove 202. The top of the first movable block 207 on one side is fixedly connected to the bottom of the first containing shell 301, and the top of the first movable block 207 on the other side is fixedly connected to the bottom of the second containing shell 302. An operating rod 208 is fixed to one end of the front bidirectional screw rod 206. The operating rod 208 passes through the drive shell 201. A positioning structure is installed on the surface of the operating rod 208, and a linkage structure is installed on the surface of the bidirectional screw rod 206.

[0042] The rotating operating rod 208 can drive the two bidirectional screw rods 206 to rotate simultaneously through the linkage structure, so that the first movable blocks 207 on both sides can be affected by the threads and begin to move toward or toward each other on the surface of the slide groove 202, so that the first containing shell 301 and the second containing shell 302 can be merged and split.

[0043] Furthermore, the surface positioning structure of the operating rod 208 includes a T-shaped pin 213, and the surface of the T-shaped pin 213 slides through a side block 212, the side block 212 is fixed to the surface of the drive housing 201, and the T-shaped pin 213 slides through the operating rod 208;

[0044] After the operating rod 208 has completed its rotation, in order to prevent the operating rod 208 from rotating on its own due to vibration, a T-shaped pin 213 can be passed through the side block 212 and the surface of the operating rod 208, so that the operating rod 208 can be positioned.

[0045] Furthermore, one end of the bidirectional screw rod 206 passes through the drive housing 201. No threads are provided on the surface where the bidirectional screw rod 206 and the drive housing 201 pass through. The bidirectional screw rod 206 is rotatably connected to the surface where the drive housing 201 passes through. The surface linkage structure of the bidirectional screw rod 206 includes a transmission wheel 209. The transmission wheel 209 is fixed to the surface of the bidirectional screw rod 206. The front and rear transmission wheels 209 are connected by a belt drive.

[0046] When the front bidirectional screw rod 206 rotates, it will drive the transmission wheel 209 on its surface to rotate together. At the same time, the transmission wheel 209 will drive the rear bidirectional screw rod 206 to rotate synchronously through the transmission with the belt, so that the rotating operating rod 208 can achieve the effect of rotating the two bidirectional screw rods 206 at the same time.

[0047] Furthermore, a guide rod 210 is fixed to the inner wall of the drive housing 201. Two second movable blocks 211 are slidably connected to the surface of the guide rod 210. The top of the second movable block 211 on one side is fixedly connected to the bottom of the first receiving housing 301, and the top of the second movable block 211 on the other side is fixedly connected to the bottom of the second receiving housing 302. The second movable block 211 is slidably connected to the surface of the slide groove 202.

[0048] When the first receiving shell 301 or the second receiving shell 302 moves, it will drive the second movable block 211 at the bottom to slide on the surface of the guide rod 210, so that they can obtain a further guiding effect and improve stability during movement.

[0049] Furthermore, the surface lifting structure of the blanking mechanism 4 includes an electric push rod 405, which is fixed to the surface of the support frame 401. One end of the electric push rod 405 passes through the support frame 401 and is fixed with a movable plate 404. Two slide rails 402 are fixed to the surface of the support frame 401. The surface of the slide rails 402 is slidably connected to the slide table 403. The movable plate 404 is fixedly connected to the surface of the slide table 403. The mounting frame 406 is fixed to the surface of the movable plate 404.

[0050] When started, the electric push rod 405 can drive the movable plate 404 to move up and down. At the same time, the movable plate 404 can drive the slide 403 to slide on the surface of the slide rail 402, thereby guiding the movable plate 404, and then the height position of the nozzle 411 can be adjusted to facilitate more accurate filling of cement and avoid collision between the solidified cement and the nozzle 411 when it is taken out upward.

[0051] Furthermore, a plurality of second U-shaped plates 308 are fixed on the top of the floating plate 303 , and pulleys 309 are fixed on the surface of the second U-shaped plates 308 ;

[0052] When the cement expands and causes the floating plate 303 to move upward, the pulley 309 will slide on the surfaces of the first containing shell 301 and the second containing shell 302, thereby providing a guiding effect for the floating plate 303 to prevent the floating plate 303 from tilting when moving up and down.

[0053] Furthermore, two protrusions 305 are fixed on the surface of the first and second containing shells 301, 302. The surface of the protrusion 305 is rotatably connected to a screw 306. The surface of the screw 306 is threadedly connected to a slider 307. The surface of the slider 307 is fixed with a pointer. The surface of the transparent observation window 304 is provided with scale lines. The screw 306 passes through the upper protrusion 305 and is fixed with a handwheel.

[0054] Rotating the handwheel can drive the screw 306 to rotate, so that the slider 307 can be affected by the thread to move up and down on the surface of the screw 306, so that the slider 307 can drive the pointer to move. Through this design, the slider 307 on one side can be moved to the basic position after cement filling, and the slider 307 on the other side can be moved to the height position after the cement expands, which makes it easier to manually observe the changes in cement expansion.

[0055] Furthermore, a fastening bolt 412 is threaded through the surface of the telescopic rod 410, and a controller 6 is fixed to the surface of the base 1. The controller 6 is electrically connected to the second motor 502, the solenoid valve 504, the first motor 407, the electric push rod 405 and the vibration motor 203;

[0056] After the telescopic rod 410 is adjusted to its telescopic length, tightening the fastening bolt 412 can increase the friction force on the surface of the telescopic rod 410, thereby enabling the telescopic rod 410 to obtain a limiting effect. The setting of the controller 6 enables it to operate multiple devices.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
