Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, and in particular to a concrete sampling device used for hydropower and water conservancy. Background Art

[0002] During the construction of hydropower and water conservancy projects, it is usually necessary to pour concrete on the foundation piles. In order to ensure the strength and other working performance of the concrete, it is usually necessary to sample the concrete poured inside the foundation piles and use a cone bucket to test the slump of the concrete.

[0003] Existing concrete sampling devices often use workers to use shovels to continuously dig concrete from concrete mixers to achieve sampling. Since the amount of concrete required for the pouring of hydropower and water conservancy foundation piles is relatively large, sampling is often performed after a certain amount of pouring. Existing work cannot quickly sample according to the progress of the foundation pile pouring, and the workload required for continuous digging with a shovel is relatively large. In the process of pouring concrete into the cone barrel, a large amount of concrete will be directly scattered on the ground, and the appropriate amount of concrete cannot be quickly collected. Workers are required to manually vibrate the concrete, further increasing the difficulty of the work. Summary of the invention

The surface of the connecting block 10 is fixedly connected with a reset spring 11, and the other end of the reset spring 11 is fixedly connected with a connecting box 12. The top of the connecting rod 602 is penetrated by the connecting box 12, and the connecting rod 602 is slidably connected to the connecting box 12, and the reset ring is sleeved with the connecting rod 602, and the locking mechanism 9 is arranged on one side of the connecting column 3. The locking mechanism 9 is used to lock or release the lifting mechanism 6 The locking mechanism 9 includes two latches 901 and a lock column 902. Two groups of bayonet holes 17 are provided on the surface of the connecting rod 602 from top to bottom. The latches 901 are engaged with the bayonet holes 17. The two latches 901 are symmetrically slidably connected to the inside of the connecting box 12.

The two connecting pins 18 are respectively penetrated by the two latches 901, and the connecting pins 18 are penetrated by the connecting box 12.

[0037] Among them, by sliding the extension handle 19 along the connecting column 3 and engaging with different holes 21 through the spring lock 20, the position of the extension handle 19 is fixed, and the use height of the device can be adjusted according to the height of the concrete in the foundation pile, which can facilitate the normal progress of subsequent sampling work, and by pulling the connecting rod 602 upward, the pull rod 601 is forced to drive the closing plate 5 to separate from the receiving barrel 1. At this time, the lock 901 is engaged with the two bayonet holes 17 located below, so as to lock the position of the connecting rod 602, and the receiving barrel 1 is inserted into the concrete of the foundation pile to dig out the concrete poured into the foundation pile. When the connecting rod 602 and the connecting block 10 slide upward, the reset spring 11 is in a compressed state. After the digging is completed, the lock 901 is forced to separate from the bayonet hole 17, and the reset spring 11 is extended from the compressed state. At this time, the closing plate 5 rotates to close the receiving barrel 1, and forces the excess concrete inside the receiving barrel 1 to flow into the replenishing barrel 2 for temporary storage.

[0038] The vibrating mechanism 7 is arranged inside the connecting column 3. The vibrating mechanism 7 is used to vibrate the concrete inside the receiving barrel 1 to make it solid. The vibrating mechanism 7 includes a vibrator 701 and a vibrating rod 702. The vibrator 701 is fixedly connected to the inside of the connecting column 3. The vibrating rod 702 is retracted and slidably connected to the bottom of the vibrator 701. The vibrating rod 702 is arranged to penetrate the inside of the feeding barrel 2, and one end of the vibrating rod 702 penetrates to the bottom of the feeding barrel 2 and is slidably connected to the inside of the receiving barrel 1.

The two extrusion plates 13 are slidably connected to the inside of the pressure box 14.

[0039] Among them, the vibrator 701 drives the vibrating rod 702 to slide up and down continuously in the receiving barrel 1, so as to form a working effect of vibrating and compacting the concrete in the receiving barrel 1. As the material height in the feeding barrel 2 decreases during the continuous compaction of the concrete, the concrete temporarily stored in the feeding barrel 2 will be automatically replenished into the receiving barrel 1 at this time, and the vibration generated by the continuous sliding effect of the vibrating rod 702 will further promote the falling effect of the concrete inside the feeding barrel 2, preventing the concrete from being unable to fall due to the gel effect of the concrete, thereby ensuring the working effect of the concrete slump test.

[0040] The blocking mechanism 8, the two blocking mechanisms 8 are slidably connected to the two sides of the inside of the feeding cylinder 2, the blocking mechanism 8 is used to close the connection state between the feeding cylinder 2 and the receiving cylinder 1, the blocking mechanism 8 includes two blocking plates 801 and two pressure bags 802, the two blocking plates 801 are symmetrically slidably connected to the two sides of the inside of the feeding cylinder 2, the two pressure bags 802 are symmetrically arranged on the two sides of the inside of the pressure box 14, and the pressure bags 802 are located above the extrusion plate 13, the bottom of the pressure bags 802 is connected with a conduit 15, the top ends of the two conduits 15 are penetrated by the extrusion plate 13, and the other ends of the two conduits 15 are respectively connected to the two sides of the feeding cylinder 2, and the two blocking plates 801 are fixedly connected to the sides away from each other with a guide head 16, and the guide head 16 is slidably connected to the inside of the feeding cylinder 2.

[0041] Among them, after the vibrating rod 702 completes the solidification work of the concrete in the receiving barrel 1, it is retracted toward the inside of the connecting column 3 through the vibrator 701. At this time, the vibrating rod 702 will drive the extrusion plates 13 on both sides to slide along the pressure box 14, and squeeze the two pressure bags 802, forcing the air inside the extrusion bags to be discharged outward through the conduit 15, and through the working effect of pushing the guide head 16 to slide inside the feeding barrel 2, drive the two blocking plates 801 to approach each other, so as to complete the closure of the bottom of the feeding barrel 2, and separate the feeding barrel 2 from the receiving barrel 1, so as to prevent the concrete in the feeding barrel 2 from affecting the concrete that has been settled in the receiving barrel 1, thereby ensuring the normal progress of the slump test.

[0042] The top of the lock column 902 is movably sleeved with a connecting ring 22, one side of the connecting ring 22 is fixedly connected to the extension handle 19, the inside of the connecting box 12 is rotatably connected with a collar 23, both sides of the surface of the collar 23 are symmetrically fixedly connected with coil springs 24, the other end of the coil spring 24 is fixedly connected to the inside of the connecting box 12, the lock column 902 and the collar 23 are penetrated, the surface of the lock column 902 is symmetrically fixedly connected with a limit strip 25, the inside of the collar 23 is symmetrically provided with two limit openings 26, the limit openings 26 and the limit strip 25 slide through and slide, the surface of the connecting block 10 is penetrated with a notch 27, the lock column 902 and the connecting pin 18 slide through and through the connecting block 10 through the notch 27.

[0043] Among them, during the extension process of the extension handle 19, the lock column 902 can be driven to slide through the connecting ring 22, which can facilitate the operation of the lock column 902 after the height adjustment is used. By twisting the lock column 902, the two connecting pins 18 can drive the two locks 901 to move away from each other. At this time, the lock 901 is separated from the bayonet 17, forcing the locking mechanism 9 to no longer lock the connecting rod 602. During the rotation of the lock column 902, the ring 23 will be driven to rotate through the limit strip 25, and the coil spring 24 is compressed at this time. The lock column 902 can be automatically reset through the reset effect of the coil spring 24, thereby driving the two locks 901 to automatically lock with the bayonet 17.

[0044] The specific working principle and method of use of the present invention are explained in detail below: When in use, the first step is to slide the extension handle 19 along the connecting column 3 and engage the extension handle 19 with different holes 21 through the spring lock 20, so as to fix the position of the extension handle 19. The height of the device can be adjusted according to the height of the concrete in the foundation pile, which can facilitate the normal subsequent sampling work. By pulling the connecting rod 602 upward, the pull rod 601 is forced to drive the closing plate 5 to separate from the receiving barrel 1. At this time, the locking 901 is engaged with the two bayonet holes 17 located below, so as to lock the position of the connecting rod 602, insert the receiving barrel 1 into the concrete of the foundation pile, and dig the concrete poured into the foundation pile. When the connecting rod 602 and the connecting block 10 slide upward, the reset spring 11 is in a compressed state. After the digging is completed, the locking 901 is forced to separate from the bayonet hole 17, and the reset spring 11 is extended from the compressed state. At this time, the closing plate 5 rotates to close the receiving barrel 1, and forces the excess concrete in the receiving barrel 1 to flow into the replenishing barrel 2 for temporary storage.

[0045] In the second step, the vibrator 701 drives the vibrating rod 702 to slide up and down continuously in the receiving barrel 1, so as to form a working effect of vibrating and compacting the concrete in the receiving barrel 1. As the concrete is continuously compacted, the material height in the feeding barrel 2 will drop. At this time, the concrete temporarily stored in the feeding barrel 2 will be automatically added to the receiving barrel 1 continuously, and the vibration generated by the continuous sliding effect of the vibrating rod 702 will further promote the falling effect of the concrete inside the feeding barrel 2, preventing it from being unable to fall due to the gel effect of the concrete.

[0046] In the third step, after the vibrating rod 702 completes the solidification of the concrete in the receiving barrel 1, it is retracted toward the inside of the connecting column 3 through the vibrator 701. At this time, the vibrating rod 702 will drive the extrusion plates 13 on both sides to slide along the pressure box 14, and squeeze the two pressure bags 802, forcing the air inside the extrusion bags to be discharged outward through the conduit 15, and through the working effect of pushing the guide head 16 to slide inside the feeding barrel 2, drive the two blocking plates 801 to move closer to each other, thereby completing the closure of the bottom of the feeding barrel 2 and separating the feeding barrel 2 from the receiving barrel 1.

[0047] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

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.
