[0048] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application will be further described below in combination with specific embodiments.

[0049] In order to be able to quickly disassemble and assemble the detection head from the cement consistency instrument, as shown in Figure 1 The present application provides a consistency instrument for cement detection, which comprises a consistency instrument support 100, a connecting block 200, a rod body 400 and a conical detection head 500. Figure 1 and Figure 2 The connecting block 200 is arranged on the consistency instrument support 100, and the conical detection head 500 is arranged at the bottom end of the rod body 400. Figure 6 As shown in Figure 3As shown, the rod body 400 is arranged inside the through hole and is slidingly mounted with the inner wall of the through hole. In use, the rod body 400 freely falls downward along the inner wall of the through hole, and the conical detection head 500 is driven to freely fall, so as to realize the detection of the cement consistency (the detailed detection is described below).

[0050] The conical detection head 500 is detachably connected with the rod body 400. In order to mount the conical detection head 500, as shown in Figure 10 As shown, the bottom end of the rod body 400 is provided with a fourth slot 430, and a cylinder 440 is fixedly mounted between the inner walls of the fourth slot 430. As shown in Figure 12 As shown, the top of the conical detection head 500 is fixedly provided with a connecting rod, which is inserted between the inner walls of the fourth slot 430. The outer surface of the connecting rod is provided with a clamping groove 510. In mounting, the user places the conical detection head 500 horizontally, first places the connecting rod horizontally into the fourth slot 430, so that it is located above the cylinder 440, and then slowly aligns the clamping groove 510 with the cylinder 440. Because the cylinder 440 and the inner wall of the clamping groove 510 are slidingly mounted, the cylinder 440 slides into the clamping groove 510. Because the conical detection head 500 has a weight, it will rotate downward under the action of its own gravity with the cylinder 440 as the rotating fulcrum. Because the top end of the connecting rod is provided with an inclined surface 520, the top wall of the fourth slot 430 is provided with an inclined surface matching the inclined surface 520, and the outer surface of the inclined surface 520 is fixedly provided with a magnet 530, which is magnetically adsorbed with the inclined surface of the top wall of the fourth slot 430, so as to fix the position of the conical detection head 500. When the conical detection head 500 is detached, it can be manually rotated in the opposite direction. Through the above arrangement, the user can improve the speed of dismounting the conical detection head 500 from the rod body 400, thereby improving the detection speed. In actual design, in order to prevent the cylinder 440 from sliding out of the clamping groove 510 when the conical detection head 500 rotates, the clamping groove 510 and the central axis of the conical detection head 500 are provided with an inclination angle, so that the cylinder 440 is not easy to slide out of the clamping groove 510. The inclination of the inclined surface 520 enables the conical detection head 500 to be limited after rotating.

[0051] In order to realize the detection of the consistency of the cement, as shown in Figure 1As shown, the consistency gauge support 100 comprises a support rod 110 and a conical barrel 120, the connecting block 200 is slidingly installed on the outer surface of the support rod 110, the other end of the connecting block 200 is threadedly connected with a locking bolt 210, one end of the locking bolt 210 abuts against the outer surface of the support rod 110, the conical detection head 500 is arranged directly above the conical barrel 120, the outer shape of the conical detection head 500 is matched with the inner wall of the conical barrel 120, the upper surface of the connecting block 200 close to one end of the rod body 400 is fixedly installed with an electronic scale 300, the rod body 400 is slidingly inserted into the electronic scale 300, after the conical detection head 500 is installed to the bottom end of the rod body 400, the height of the connecting block 200 on the support rod 110 is manually adjusted, so that the bottom tip of the conical detection head 500 is located at the barrel opening position of the conical barrel 120 and is flush with the barrel opening of the conical barrel 120, then the height position of the connecting block 200 is fixed by tightening the locking bolt 210, and then the height of the conical detection head 500 is fixed, at this time, the scale on the electronic scale 300 is cleared, and then the rod body 400 and the conical detection head 500 are suddenly released, so that the conical detection head 500 freely falls into the cement inside the conical barrel 120, and then the falling height displayed on the electronic scale 300 is recorded, so as to detect the consistency of the cement.

[0052] In order to limit the position of the rod body 400 on the connecting block 200 and enable sudden release, Figure 4 , Figure 7 and Figure 13 As shown, the inner wall of the through hole of the connecting block 200 is provided with a first cavity 220, the top of the first cavity 220 is provided with a conical surface 230, the outer surface of the rod body 400 is slidingly sleeved with a spring sleeve 700, the spring sleeve 700 is arranged inside the first cavity 220, the outer surface of the spring sleeve 700 is provided with a conical surface matched with the conical surface 230, a plurality of U-shaped openings are equidistantly formed on the circumferential outer surface of the spring sleeve 700, when the spring sleeve 700 is driven to move upward, the conical surface of the outer surface of the spring sleeve 700 will contact and abut against the conical surface 230, and because of the arrangement of the U-shaped openings, the spring sleeve 700 can be elastically contracted, so as to clamp the rod body 400, and through the arrangement, the rod body 400 can be fixed at the fixed position of the connecting block 200.

[0053] In actual use, in order to limit the rod body 400 to move up and down along the axial direction only and not to rotate, as shown in Figure 8 and Figure 10 The circumferential outer surface of the rod body 400 is provided with a third groove 410, the inner wall of the through hole is provided with a protruding portion 270, the protruding portion 270 is slidingly installed on the inner wall of the third groove 410, and the cooperation of the protruding portion 270 and the third groove 410 limits the rod body 400 to move up and down only and not to rotate.

[0054] The existing release of the rod body 400 by loosening the bolt is prone to errors in detection results because the bolt loosening needs to consider the speed of the operator's hand, so as to quickly and suddenly achieve the effect of releasing the rod body 400. Figure 7 And Figure 8 As shown in the first cavity 220, the inner wall of the second cavity 240 is provided with a first slot 250, the bottom end of the spring sleeve 700 is fixedly installed with a top rod 710, the top rod 710 is slidably installed with the inner wall of the first slot 250, the top end of the top rod 710 is fixedly connected with the first spring 720, the top end of the first spring 720 is fixedly connected with the top wall of the first slot 250, through the cooperation of the top rod 710 and the first slot 250, the spring sleeve 700 can only move along the central axis direction of the rod body 400, as shown in Figure 5 Because the connecting block 200 is rotatably installed with a knob 600 near one end of the rod body 400, one end of the knob 600 penetrates the second cavity 240 and is fixedly installed with a disc cam 800, the bottom end of the top rod 710 abuts against the circumferential outer surface of the disc cam 800, when the knob 600 rotates, it will drive the disc cam 800 to rotate, at this time, the bottom end of the top rod 710 will slide on the circumferential outer surface of the disc cam 800, because as shown in Figure 11 The circumferential outer surface of the disc cam 800 is provided with a fracture, when the bottom end of the top rod 710 relatively slides to the position of the fracture, under the action of the force of the first spring 720, the spring sleeve 700 will slide downward, thereby releasing the clamping of the rod body 400, because the elastic force of the first spring 720 is released instantaneously, so it is faster than the speed of manually loosening the bolt by hand, and the detection data is more accurate.

[0055] Because when detecting the consistency of cement, the conical detection head 500 must be kept in a completely vertical state, the conical detection head 500 and the rod body 400 must be completely installed in place, in order to solve this problem, in the embodiment, as shown in Figure 4 , Figure 11 And Figure 13As shown, the disc cam 800 is provided with a mounting groove 810 near the end face of the rod body 400, the inner wall of the mounting groove 810 is slidably installed with a T-shaped clamping block 900, the cross section of the T-shaped clamping block 900 is T-shaped (by T-shaped setting to avoid the T-shaped clamping block 900 from being pulled out of the mounting groove 810), the bottom end of the T-shaped clamping block 900 penetrates the circumferential outer surface of the disc cam 800, when the T-shaped clamping block 900 rotates to the upper side with the disc cam 800, under its own gravity, it will move downward and retract into the mounting groove 810, at this time, the bottom end of the T-shaped clamping block 900 is in contact with the circumferential outer surface of the disc cam 800, so as not to affect the sliding of the bottom end of the ejector rod 710 on the circumferential outer surface of the disc cam 800, since the bottom wall of the second cavity 240 is provided with a second groove 260, the inner wall of the second groove 260 is slidably installed with an L-shaped rod 1000, the other end of the L-shaped rod 1000 is fixedly connected with a third spring 1500, the other end of the third spring 1500 is fixedly connected with the inner wall of the second groove 260, the L-shaped rod 1000 is kept in a fixed position of the second groove 260 through the third spring 1500, so that when the T-shaped clamping block 900 rotates to the lower side, the top end of the L-shaped rod 1000 abuts against the outer surface of the T-shaped clamping block 900, thereby limiting the continuous rotation of the disc cam 800, so that the ejector rod 710 cannot slide to the position of the break of the disc cam 800, thereby the spring collet 700 cannot release the clamping of the rod body 400, through the above setting, when the conical detection head 500 and the rod body 400 are not completely installed in place, the spring collet 700 cannot be loosened.

[0056] In order to release the abutment of the top end of the L-shaped rod 1000 against the outer surface of the T-shaped clamping block 900 when the conical detection head 500 and the rod body 400 are completely installed in place, as shown in Figure 10 and Figure 13 As shown, the inside of the rod body 400 is provided with a second insertion hole 460, the inner wall of the second insertion hole 460 is slidably inserted with a driving rod 1100, the top end of the driving rod 1100 abuts against one end of the L-shaped rod 1000, when the conical detection head 500 is not installed in place, one end of the L-shaped rod 1000 is inserted into the outlet at the top end of the second insertion hole 460, when the conical detection head 500 is installed in place, the driving rod 1100 is driven to move towards the L-shaped rod 1000, thereby ejecting one end of the L-shaped rod 1000 from the outlet at the top end of the second insertion hole 460, so that the top end of the L-shaped rod 1000 is separated from the outer surface of the T-shaped clamping block 900 and no longer abuts against, thereby releasing the limitation of the disc cam 800.

[0057] In order to drive the driving rod 1100 to move towards the L-shaped rod 1000, as shown in Figure 5 and Figure 9As shown, the outer circumferential surface of the rod body 400 near the bottom end is provided with an opening 420, the top wall and the bottom wall of the opening 420 are provided with a first insertion hole 450, the first insertion hole 450 of the top wall of the opening 420 is slidably inserted with a second pin 1400, the first insertion hole 450 of the bottom wall of the opening 420 is slidably inserted with a first pin 1200, the first pin 1200 and the second pin 1400 are fixedly connected between the adjacent ends of the first pin 1200 and the second pin 1400, the bottom end of the first pin 1200 penetrates the bottom end of the rod body 400 and abuts against the inclined surface 520, the top end of the second pin 1400 penetrates the bottom wall of the third groove 410 and abuts against the lower surface of the protruding portion 270, the outer surface of the first pin 1200 is fixedly connected with a block 1210, the outer surface of the block 1210 is provided with a sliding groove 1211, the bottom end of the driving rod 1100 is fixedly installed on the outer surface of the rod body 400 and is provided with a sliding column 1110, the sliding column 1110 is slidably installed on the inner wall of the sliding groove 1211, through the installation of the conical detection head 500, the inclined surface 520 abuts against the bottom end of the first pin 1200, the first pin 1200 is driven to slide upward, the block 1210 is driven to move upward by the first pin 1200, the block 1210 drives the driving rod 1100 to move in the direction close to the L-shaped rod 1000 through the cooperation of the sliding column 1110 and the sliding groove 1211, so that the top end of the driving rod 1100 abuts against the outer circumferential surface of the rod body 400, at the same time, the L-shaped rod 1000 is driven to move in the direction away from the rod body 400, so that the top end of the L-shaped rod 1000 is away from the outer surface of the T-shaped clamping block 900.

[0058] When the conical detection head 500 is detected, the user first separates the conical detection head 500 and the rod body 400, at this time, the driving rod 1100 is reset under the action of the second spring 1300, the outlet of the top end of the second insertion hole 460 exposes a space, then the user pulls the rod body 400 upward until one end of the L-shaped rod 1000 is inserted into the outlet of the top end of the second insertion hole 460, at this time, the rod body 400 is clamped again by rotating the disc cam 800, then the top end of the L-shaped rod 1000 abuts against the outer surface of the T-shaped clamping block 900, and the rotation position of the disc cam 800 is limited.

[0059] It should be noted that the first pin 1200 and the second pin 1400 are arranged to remind the operator that the conical detection head 500 should be removed first when the rod body 400 is pulled to reset completely without removing the conical detection head 500 first, because the first pin 1200 is abutted by the inclined surface 520, so the second spring 1300 is compressed, when the second pin 1400 abuts against the lower surface of the protruding portion 270, the elastic reaction force increases obviously, reminding the operator that the conical detection head 500 should be removed first, otherwise the L-shaped rod 1000 cannot correctly limit the disc cam 800.

[0060] In the embodiment, the first pin 1200 and the second pin 1400 are T-shaped in cross section and square in shape, thereby being limited in the installation position of the first socket 450 and not slipping and rotating.

[0061] In the embodiment, the L-shaped rod 1000 is square in shape, so that it can only slide along the second groove 260.

7. A method for testing the consistency of cement, characterized in that, The consistency meter for cement testing as described in claim 6 includes the following steps: S1: The user places the conical detection head (500) horizontally, first places the connecting rod horizontally inside the fourth groove (430) so that it is located on the upper part of the cylinder (440), and then slowly aligns the slot (510) with the cylinder (440). Because the cylinder (440) and the inner wall of the slot (510) are slidably installed, the cylinder (440) slides into the slot (510) and is magnetically attracted by the magnet (530) and the inclined surface of the top wall of the fourth groove (430), thereby fixing the position of the conical detection head (500). S2: By manually adjusting the height of the connecting block (200) on the support rod (110), the tip of the bottom of the cone-shaped detection head (500) is positioned at the mouth of the cone (120) and is flush with the mouth of the cone (120). Then, the height of the connecting block (200) is fixed by tightening the locking bolt (210), thereby fixing the height of the cone-shaped detection head (500). Finally, the scale on the electronic ruler (300) is manually cleared to zero. S3: When the spring clip (700) is driven to move upward, the conical surface of the outer surface of the spring clip (700) will contact and abut against the conical surface (230). Due to the U-shaped opening, the spring clip (700) can elastically contract, thereby clamping the rod (400). S4: When the bottom end of the push rod (710) slides to the position of the break, it will cause the spring sleeve (700) to slide downward under the force of the first spring (720), thereby releasing the clamping of the rod body (400); S5: When the conical detection head (500) is installed in place, the drive rod (1100) is driven to move closer to the L-shaped rod (1000), thereby pushing one end of the L-shaped rod (1000) out of the outlet at the top of the second insertion hole (460), thereby separating the top of the L-shaped rod (1000) from the outer surface of the T-shaped block (900).
