Description

Technical Field

[0001] This invention relates to the field of building material testing technology, and in particular to a high-efficiency testing device for testing the quality of building materials. Background Technology

[0002] Concrete is a building material used in construction. When pouring concrete, it is usually done by a concrete pump truck. After the concrete arrives at the construction site, the site needs to conduct demolding and testing. This involves filling the concrete into molds and then storing the molds. Filling the molds is a sampling process, and storing the molds is a transportation and storage process. These processes are currently all done manually. During these manual processes, human actions such as replacing or swapping samples can occur, affecting the test results and leading to inaccurate test results. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a highly efficient testing device for detecting the quality of building materials.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-efficiency testing device for detecting the quality of building materials, comprising a concrete pump truck with a concrete pipe, a discharge opening on the concrete pipe, a track and a support below the concrete pipe, a limit block at the rear end of the track, and a sampling box slidably mounted on the track. When the sampling box touches the limit block, the sampling box aligns with the discharge opening, allowing concrete from the concrete pipe to enter the sampling box. The support is provided with a guide post and a locking element. A support element is slidably mounted on the guide post, and the locking element locks the support element. A sliding opening is provided on the guide rail. When the sampling box touches the limit block, it is entirely located at the sliding opening. At this time, the lower end of the sampling box touches the support element, and the upper end of the sampling box touches the concrete pipe. The support element includes a shell, a moving device, and an energy storage device. The moving device includes a sliding shell, which is elastically slidably mounted inside the shell. A conveyor belt is mounted on the sliding shell, and the upper end of the conveyor belt is higher than the upper end of the shell. The shell has a first contact block with its front end extending beyond the front end of the outer shell. The support has an inclined block. The energy storage device includes a cup sleeve, a rotating shaft, and an energy storage locking element. The cup sleeve is mounted on the drive wheel of the conveyor belt, and a spiral spring is installed inside the cup sleeve. A sliding groove is formed inside the outer shell, and a sliding element is slidably mounted within the sliding groove. The rotating shaft is unidirectionally mounted within the sliding element, with one end connected to the middle position of the spiral spring, and the other end unidirectionally mounted with a rolling wheel. A friction block is mounted on the support, and the rolling wheel contacts the friction block. The cup sleeve... A groove is provided on the outer side, and an energy storage locking component is set on the outer shell with its front end touching the groove to lock the cup sleeve. When the locking component is unlocked, the support component moves downward under the weight of the sampling box. The rolling wheel rotates due to friction with the friction block, which drives the rotating shaft to rotate and tightens the spiral spring. The first contact block touches the inclined block, causing the sliding shell to slide backward, so that the rear end of the conveyor belt exceeds the rear end of the outer shell. At the same time, the cup sleeve is disengaged from the energy storage locking component, the cup sleeve is unlocked, and the conveyor belt rotates, moving the sampling box outward.

[0005] Its beneficial effects are that it can automatically collect random samples from inside the concrete pipe. After sampling is completed, the sampling box can automatically slide down. When it slides to the lowest point, the sampling box is automatically moved to the lower track for storage. This process is completed automatically, avoiding human intervention, making sampling more efficient, and making the test results more representative.

[0006] In the above scheme, preferably, the guide post is fitted with a first elastic element, the two ends of which respectively abut against the lower end face of the support member and the lower end of the bracket.

[0007] In the above scheme, preferably, the locking component includes an electromagnet with a locking head slidably mounted on it, and a second elastic element is provided between the locking head and the electromagnet in contact. When the electromagnet is energized, it can attract the locking head backward.

[0008] In the above scheme, preferably, the bracket is also provided with a lower track and a lower limit block. The support slides down the sampling box and finally presses against the lower limit block. At this time, pushing the sampling box will allow it to slide into the lower track.

[0009] In the above scheme, preferably, the energy storage locking component includes a piston tube and a piston rod. The piston tube is disposed inside the outer casing, and the piston rod is slidably disposed inside the piston tube. The rear end of the piston rod abuts against one end where a third elastic element is disposed, and the other end abuts against the end wall of the piston tube. The front end of the piston rod abuts against a groove.

[0010] In the above scheme, preferably, when the support member presses against the lower limit block, the piston rod extends outward to its longest position, and the front end of the piston rod leaves the groove, and the cup sleeve contacts and locks.

[0011] In the above scheme, preferably, multiple grooves are evenly provided on the outer wall of the bowl sleeve, the width of the grooves is the same as the diameter of the piston rod, and the front end of the piston rod is provided with a chamfer.

[0012] The beneficial effects of this invention are: This invention provides a highly efficient testing device for detecting the quality of building materials. It can automatically and randomly sample materials falling from concrete pipes without human intervention. After sampling is completed, the sampling box can automatically slide downwards. When it slides to the lowest point, the sampling box is automatically moved to the lower track for storage. The process is fully automated, avoiding human intervention, making sampling more efficient, and making the test results more representative. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-8 ,

[0022] A high-efficiency testing device for detecting the quality of building materials includes a concrete pump truck with a concrete pipe 1 and a discharge opening. Three trigger switches are installed inside the concrete pipe 1. A track 2 and a support 3 are located below the concrete pipe 1. A limit block 21 is installed at the rear end of the track 2, and a pressure switch is installed on the limit block 21. A sampling box 22 for storing concrete samples slides along the track 2. The sampling box 22 is transported from the previous process to below the discharge opening of the concrete pipe 1. When the sampling box 22 touches the limit block 21, it simultaneously presses the pressure switch, which in turn powers the trigger switches. Meanwhile, concrete continuously flows through the concrete pipe 1. When the stones in the concrete simultaneously impact the three trigger switches, the discharge opening opens, and the concrete in the concrete pipe 1 automatically flows into the sampling box 22. After the discharge opening has been open for a certain period, it automatically closes.

[0023] The bracket 3 is provided with a guide post 31 and a locking member 32. A support member 4 is slidably arranged on the guide post 31, and a first elastic member 311 is sleeved on the guide post 31. Its two ends respectively abut against the lower bottom surface of the support member 4 and the bottom surface of the bracket 3. The bracket 3 is also provided with an upper limit block 312 and a lower limit block 313. In the initial state, the support member 4 abuts against the upper limit block 312 under the action of the first elastic member 311. The locking member 32 includes an electromagnet 321, which is arranged on the bracket 3. The electromagnet 321 has a locking head 322 that is slidably arranged on the piston of the electromagnet 321. A second elastic member 323 abuts against the locking head 322 and the electromagnet 321. When the electromagnet 321 is energized, it can attract the locking head 322 backward. The guide post 31, the locking member 32, and the support member 4 are arranged symmetrically from left to right.

[0024] The locking head 322 has a sloping lower end and a flat upper end. In the initial state, the upper flat surface of the locking head 322 contacts the lower flat surface of the support member 4, thus preventing the support member 4 from sliding downward and locking it. The track 2 has a sliding opening 23 at the front end of the limiting block 21, through which the sampling box 22 can slide downward. At this time, the support member 4 is locked by the locking head 322, the bottom surface of the sampling box 22 touches the support member 4, and the upper flat surface is level with the concrete pipe 1, thus preventing the sampling box 22 from falling. After the material discharge opening is opened, the concrete in the concrete pipe 1 can enter the sampling box 22. After the material discharge opening has been open for a certain period of time, that is, after the sampling box 22 is full, the material discharge opening automatically closes. At the same time, the electromagnet 321 is energized, which pulls the locking head 322 backward, causing the locking head 322 to leave the bottom of the support member 4. The support member 4 slides downward under the weight of the full sampling box 22, compressing the first elastic member 311.

[0025] The support member 4 includes a housing 41, a moving device 42, and an energy storage device 43. The housing 41 has a belt groove 411. The moving device 42 includes a sliding shell 421, which is slidably mounted on the belt groove 411. A conveyor belt 422 is mounted on the sliding shell 421, with its upper surface extending beyond the upper surface of the housing 41. The sampling box 22 slides to the sliding opening 23, and its lower end face presses against the conveyor belt 422. 422 includes a driving wheel 4221, a driven wheel 4222, and a belt 4223. The driving wheel 4221 and the driven wheel 4222 are rotatably mounted on the sliding housing 421. The belt 4223 connects the driving wheel 4221 and the driven wheel 4222. The energy storage device 43 includes a cup sleeve 431, a rotating shaft 432, and an energy storage locking element 433. One end of the driving wheel 4221 is connected to the cup sleeve 431. The outer end of a spiral spring 434 is connected to the inner wall of the cup sleeve 431.

[0026] The outer casing 41 has a sliding groove 412, and a sliding member 413 is slidably disposed in the sliding groove 412. The rotating shaft 432 is unidirectionally rotatable in the sliding member 413, and one end is connected to the inner end of the spiral spring 434. The other end is unidirectionally rotatable with a rolling wheel 4321. A friction block 34 is disposed on the bracket 3. The rolling wheel 4321 abuts against the friction block 34. Multiple grooves 435 are evenly distributed on the outer wall of the cup sleeve 431. The energy storage locking member 433 includes a piston tube 4331 and a piston rod 4332. The piston tube 4331 is disposed in the outer casing 41. The piston rod 4332 is slidably disposed in the piston tube 4331. The rear end of the piston rod 4332 abuts against one end of a third elastic member 4333, and the other end abuts against the end wall of the plug tube 4331. The front end of the piston rod 4332 abuts against the groove 435 for locking the cup sleeve 431.

[0027] After the locking head 322 moves backward, the support member 4 slides downward under the gravity of the sampling box 22. The rolling wheel 4321 at the upper end of the support member 4 rotates relative to the friction block 34. The rolling wheel 4321 rotates, driving the rotating shaft 432 to rotate. At this time, the cup sleeve 431 is locked by the energy storage locking member 433. Therefore, the rotating shaft 432 rotates and tightens the spiral spring 434.

[0028] The outer shell 41 is also provided with a fourth elastic element 424, the two ends of which respectively abut against the sliding shell 421 and the sliding cavity inside the outer shell 4. Under the action of the fourth elastic element 424, the outer shell 41 is located in the belt groove 411 in the initial state. The outer shell 41 is also provided with a first abutting block 423, which extends forward and the front end extends beyond the front end of the outer shell 41. The bracket 3 is provided with an inclined block 33.

[0029] The support member 4 slides downward, and the first top contact block 423 on it can contact the inclined block 33, thereby causing the first top contact block 423 to retract inward, thereby pushing the sliding shell 421 to slide backward, while compressing the fourth elastic member 424. As the sliding shell 421 slides backward, the rear end of the conveyor belt 422 exceeds the rear end of the outer shell 41.

[0030] The bracket 3 is also equipped with a lower track 35 and a lower limit block 313. The support member 4 slides downward under the action of the sampling box 22 and finally presses against the lower limit block 313. At this time, the height of the sampling box 22 is just enough to slide into the lower track 35 to the side. At this time, the first top contact block 423 is completely retracted into the outer shell 41 under the action of the inclined block 33. The sliding shell 421 moves backward to the outermost end. At the same time, since the cup sleeve 431 moves backward with the sliding shell 421, the piston rod 4332 extends outward. When the sliding shell 421 moves backward to its outermost position, the piston rod 4332 extends outward to its longest position, and the front end of the piston rod 4332 leaves the groove 435. The cup sleeve 431 is unlocked. At the same time, the rotating shaft 432 rotates unidirectionally within the sliding member 413. Under the reaction of the spiral spring 434, the rotating shaft 432 does not rotate. Therefore, when the cup sleeve 431 is unlocked, the cup sleeve 431 rotates, thereby driving the conveyor belt 422 to rotate, and driving the sampling box 22 to leave the support member 4 and enter the lower track 35.

[0031] After the sampling box 22 is completely separated from the support member 4, the support member 4 slides upward under the action of the first elastic member 311. A pressure switch is provided on the lower end surface of the upper limit block 312. When the support member 4 slides upward and touches the upper limit block 312, it presses the pressure switch. The pressure switch controls the electromagnet 321 to be de-energized, so that the locking head 322 is pushed forward under the action of the second elastic member 323 and returns to the support member 4, locking the support member 4.

[0032] When the top touches the inclined block 33, the sliding shell 421 slides backward. At the same time as unlocking the bowl cover 431, the sampling box 22 can move out of the travel trajectory of the support member 4, so that the support member 4 will not touch the sampling box 22 when it rises, and the sampling box 22 is stored on the lower track 35.

[0033] Its working principle or usage method is as follows:

[0034] The sampling box 22 is transported from the previous process to below the discharge opening of the concrete pipe 1. When the sampling box 22 touches the limit block 21, it simultaneously presses the pressure switch. The pressure switch controls the power supply to the trigger switch. At this time, concrete continues to flow through the concrete pipe 1. When the stones in the concrete hit the three trigger switches at the same time, the discharge opening is opened, and the concrete in the concrete pipe 1 automatically flows into the sampling box 22. After the discharge opening is open for a certain period of time, it automatically closes. At the same time, the electromagnet 321 is energized, which pulls the locking head 322 backward, so that the locking head 322 leaves the support member 4. The support member 4 slides downward under the weight of the full sampling box 22, compressing the first elastic member 311.

[0035] The support 4 slides downward under the gravity of the sampling box 22. The rolling wheel 4321 at the upper end of the support 4 rotates relative to the friction block 34. The rolling wheel 4321 rotates, driving the rotating shaft 432 to rotate. At this time, the cup sleeve 431 is locked by the energy storage locking member 433. Therefore, the rotating shaft 432 rotates and tightens the spiral spring 434.

[0036] When the support member 4 slides down to near the lower limit block 313, the first top contact block 423 on the support member 4 can contact the inclined block 33, thereby causing the first top contact block 423 to retract inward, thereby pushing the sliding shell 421 to slide backward, while compressing the fourth elastic member 424. As the sliding shell 421 slides backward, the rear end of the conveyor belt 422 exceeds the rear end of the outer shell 41.

[0037] When the support 4 presses against the lower limit block 313, the height of the sampling box 22 is just enough to slide into the lower track 35 from the side. At this time, the first top contact block 423 is completely retracted into the outer shell 41 under the action of the inclined block 33. The sliding shell 421 moves backward to the outermost end. At the same time, since the cup sleeve 431 moves backward with the sliding shell 421, the piston rod 4332 extends outward. When the sliding shell 421 moves backward to the outermost end, the piston rod 4332 extends outward to its longest position, and the front end of the piston rod 4332 leaves the groove 435. The cup sleeve 431 is unlocked. At the same time, the rotating shaft 432 rotates unidirectionally in the sliding member 413. Under the reaction of the spiral spring 434, the rotating shaft 432 does not rotate. Therefore, when the cup sleeve 431 is unlocked, the cup sleeve 431 rotates, thereby driving the conveyor belt 422 to rotate, driving the sampling box 22 to leave the support 4 and enter the lower track 35.

[0038] After the sampling box 22 completely leaves the support member 4, the support member 4 slides upward under the action of the first elastic member 311, the first top contact block 423 disengages from the inclined block 33, and the sliding shell 421 slides inward to the initial position under the action of the fourth elastic member 424. At this time, the front end of the piston rod 4332 touches the groove 435 again, locking the cup sleeve 431.

[0039] A pressure switch is provided on the lower end face of the upper limit block 312. When the support member 4 slides upward and touches the upper limit block 312, it presses the pressure switch. The pressure switch controls the electromagnet 321 to de-energize, so that the locking head 322 is pushed forward under the action of the second elastic member 323 and returns to the support member 4, locking the support member 4.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
