TECHNICAL FIELD

[0001] The present application relates to the technical field of gypsum mold casting, in particular to a continuous grouting method with self-positioning function. BACKGROUND

[0002] The gypsum mold grouting process refers to the process of mixing alpha gypsum mixture with water in a mixing tank according to a certain proportion to become gypsum slurry, and then pouring the slurry into a sand box in which a fusible model is placed through a grouting tank, and filling the sand box. The gypsum slurry is filled into the sand box for a certain period of time, and then a hydration reaction occurs and finally solidifies.

[0003] The existing gypsum mold grouting tank is generally cylindrical, and there are vertical top-opening and horizontal side-opening two types. These two types of equipment have the following disadvantages:

[0110] Further, in the step S2, the tank body 1 is provided with an observation window 6; during the grouting process, the operator observes whether the sand box 25 is grouted through the observation window 6.

[0111] Further, in the step S3, the slide rail frame 14 is provided with a pin hole 22, and the sliding platform is provided with a pin 24; after the sliding platform is slid to the transfer trolley, the pin 24 on the sliding platform is inserted into the pin hole 22 on the slide rail frame 14, so as to fix the sliding platform on the transfer trolley, and then the transfer trolley is pushed to displace to transfer the sand box 25 after grouting.

[0112] Specifically, in the step S1, the process of sliding the sliding platform from the transfer trolley to the grouting tank is as follows:

[0113] Step S11: The positioning pin 28 at the end of the slide rail frame 14 is inserted into the positioning insertion hole 501 of the slide rail 5, so as to butt the slide rail frame 14 of the transfer trolley with the slide rail 5;

[0115] Step S13: The sliding platform is slid along the slide rail frame 14 and the slide rail 5, and is transferred from the transfer trolley to the inside of the grouting tank.

[0116] In the step S12, as shown in Figure 14 When the positioning pin 28 on the slide rail frame 14 is inserted into the positioning insertion hole 501: the positioning pin 28 slides along the slope surface, and in turn can push the slope surface to displace, and in turn push the locking pin 502 to retract into the locking pin mounting hole 505 while compressing the first spring 506; when the locking pin 502 retracts into the locking pin mounting hole 505, the sliding platform can slide along the slide rail 5.

[0117] In the step S13, after the sliding platform is transferred to the grouting tank, the transfer trolley is separated from the grouting tank, and the positioning pin 28 is pulled out of the positioning insertion hole 501: when the positioning pin 28 is removed from the positioning insertion hole 501, the locking pin 502 is reset under the elastic force of the first spring 506, and the locking pin 502 protrudes from the side surface of the slide rail 5 under the pushing of the first spring 506, so as to limit the sliding platform, and keep the sliding platform from sliding during grouting.

[0118] Specifically, in the step S2, the grouting process of the sand box 25 is as follows:

[0119] Step S21: An annular sealing strip 11 is arranged at the port of the tank body 1; when the sealing cover 2 is covered with the tank body 1, the sealing strip 11 is in contact with the sealing cover 2 and is sealed;

[0120] Step S22: A gas pipeline interface 7 is arranged on the tank body 1; the gas pipeline interface 7 is connected with a vacuum pump; the vacuum pump is started to extract the gas in the grouting tank, so that the grouting tank is in a negative pressure state; and then the slurry in the slurry box is extracted into the tank body 1 through the negative pressure in the tank body 1.

[0121] Step S23: After the slurry enters the grouting tank, it flows out through the drainage pipe 20 and then flows into the sand box 25 below the drainage pipe 20.

[0122] Specifically, in the step S3, the process of sliding the platform from the grouting tank to the transfer trolley is as follows:

[0123] Step S31: The positioning pin 28 at the end of the slide rail frame 14 is inserted into the positioning insertion hole 501 of the slide rail 5, so that the slide rail frame 14 of the transfer trolley is docked with the slide rail 5.

[0124] Step S32: After the positioning pin 28 is inserted into the positioning insertion hole 501, it is in contact with the slope surface of the trapezoidal slide groove 504 on the locking pin 502; the positioning pin 28 continues to displace along the positioning insertion hole 501, while pushing the locking pin 502 to retract into the locking pin mounting hole 505; the blocking and positioning of the sliding platform by the locking pin 502 is released.

[0125] Step S33: The sliding platform slides from the slide rail 5 to the slide rail frame 14 until the positioning plate 21 on the sliding platform and the slide rail frame 14 is in contact; the transfer of the sliding platform from the grouting tank to the transfer trolley is completed, and the sand box 25 after grouting is transferred to the transfer trolley.

[0126] Further, after the sliding platform is transferred to the transfer trolley, the transfer trolley is separated from the grouting tank, the positioning pin 28 is removed from the positioning insertion hole 501, and the locking pin 502 is reset.

[0127] The continuous grouting method provided in the embodiment synchronously realizes the pressing or popping of the locking pin 502 in the locking pin mounting hole 505 through the insertion or separation of the positioning pin 28 and the positioning insertion hole 501, and then realizes the blocking or releasing of the sliding platform, guarantees the position accuracy of the sand box 25 during grouting, and further guarantees the reliability of grouting.

[0128] In this embodiment, by setting a locking pin 502 and a first spring 506, the slide rail 5 and the slide rail frame 14 are unlocked when docking and locked after separation.

Specifically, the traction ring 23 is used when the sliding platform is moved; when the sliding platform needs to be moved, the traction ring 23 is hooked by a tool, so that the sliding platform can slide on the slide rail 5 or between the slide rail 5 and the slide rail frame 14.

[0146] Further, as shown in Figure 4 、 Figure 7 , a group of through holes 12 are arranged on the side of the slide rail 5 inside the tank body 1, and the through holes 12 are used for inserting a brake latch to prevent the sliding platform from sliding during grouting.

[0147] In one specific embodiment of the present application, the transfer trolley comprises a slide rail frame 14 and a transfer trolley base 15, as shown in Figure 12 .

[0148] Specifically, as shown in Figure 12 , the slide rail frame 14 is provided with a baffle 16 on the outside, which is used to limit the sliding platform inside the slide rail frame 14, so as to prevent the sliding platform from disengaging from the slide rail frame 14.

At the same time when the gas in the grouting tank is extracted, the slurry in the slurry tank is affected by the negative pressure and enters the grouting tank through the grouting interface 8, and is distributed to each sand box 25 through the distribution pipeline 9 and the flow distributor, so that the synchronous grouting of the multiple sand boxes 25 is realized.

[0155] Further, the tank body 1 is further provided with a pressure gauge 10, which is used for monitoring the air pressure in the grouting tank.

[0159] Further, the transfer trolley is provided with a transfer trolley handle 27; the transfer trolley handle 27 is fixedly installed at the end of the transfer trolley base 15, and is used for facilitating the displacement of the transfer trolley.

[0160] In one specific embodiment of the present application, the grouting tank and the transfer trolley are improved:

[0161] In order to realize the effective connection of the slide rail frame 14 and the slide rail 5 and ensure the smooth transfer of the sliding platform between the slide rail 5 and the slide rail frame 14, the present application realizes the effective connection of the slide rail 5 and the slide rail frame 14 by arranging a positioning pin 28 and a positioning hole 501.

[0162] As shown in Figure 12 , Figure 13As shown, the end of the slide rail frame 14 is fixedly provided with a positioning pin 28, and the end of the slide rail 5 is provided with a positioning hole 501, and the positioning pin 28 and the positioning hole 501 are matched. When the positioning pin 28 is inserted into the positioning hole 501, the abutment of the slide rail 5 and the slide rail frame 14 on the transfer trolley is completed. Further, in order to realize that the sliding platform is fixed to the slide rail 5 during grouting, the sliding platform can slide along the slide rail 5 after grouting is completed. The embodiment is provided with a locking and positioning assembly at both ends of the slide rail 5, as shown. Figure 14

[0163] As shown in the drawings, Figure 14 The locking and positioning assembly comprises a locking pin 502, a fixed plate 503 and a first spring 506. Specifically, the slide rail 5 is provided with a locking pin mounting hole 505, which is perpendicular to the positioning hole 501. The locking pin 502 is slidingly installed in the locking pin mounting hole 505, and the locking pin 502 protrudes from the side surface of the slide rail 5. The first spring 506 is also arranged in the locking pin mounting hole 505. The end of the locking pin mounting hole 505 is fixedly installed with the fixed plate 503 by welding, and the first spring 506 is arranged between the locking pin 502 and the fixed plate 503. Specifically, the two ends of the first spring 506 are welded and fixed with the locking pin 502 and the fixed plate 503, respectively.

[0164] Further, as shown in the drawings, Figure 15 The middle part of the locking pin 502 is provided with a trapezoidal sliding groove 504. The trapezoidal sliding groove 504 is communicated with the positioning hole 501, and the trapezoidal sliding groove 504 has an inclined surface, which is opposite to the positioning hole 501.

[0165] During installation, the two ends of the first spring 506 are welded and fixed with the locking pin 502 and the fixed plate 503 to form an integral body. Then, the locking pin 502 and the first spring 506 are inserted into the locking pin mounting hole 505. Finally, the fixed plate 503 is welded and fixed with the slide rail 5. The sliding installation of the locking pin 502 in the locking pin mounting hole 505 is completed. When the locking pin 502 protrudes from the slide rail 5, the sliding of the sliding platform relative to the slide rail 5 can be blocked.

[0166] When the sliding platform is placed inside the grouting tank and the grouting tank is grouting the sand box 25, the locking pins 502 on both sides of the slide rail 5 can position the sliding platform, limit the sliding of the sliding platform, and keep the position accuracy during the grouting process. When the locking pin 502 is pressed into the inside of the locking pin mounting hole 505 by the positioning pin 28, the first spring 506 is in a compressed state, and at this time, the locking pin 502 releases the positioning of the sliding platform, and the sliding platform can slide along the slide rail 5 to the slide rail frame 14, and then the sand box 25 after grouting is transferred to the transfer trolley.

[0167] ​The embodiment achieves the locking and positioning of the sliding platform and the sand box 25 by the locking pin during the grouting, and the locking pin 502 releases the limiting effect on the sliding platform when the sliding rail frame 14 and the sliding rail 5 are connected.

[0168] Further, considering that the residual slurry will be left on the inner wall surface of the drainage pipe 20 during the slurry flowing out of the drainage pipe 20, the residual slurry will solidify after a certain period of time, causing the blockage of the drainage pipe 20. Therefore, the drainage pipe 20 needs to be replaced regularly.

[0169] In a specific embodiment of the present application, in order to realize the quick disassembly and installation of the drainage pipe 20, the specific structure of the drainage device is improved on the basis of the embodiment 1 or the embodiment 2:

[0170] Specifically, the inner diameter of the drainage pipe 20 is the same as the outer diameter of the drainage device interface 19; the drainage pipe 20 is connected with the interface branch pipe 192 of the drainage device interface 19 through the plug-in connection, and is fastened through the lock catch assembly or the snap ring assembly.

[0171] 1 When fastened through the lock catch assembly:

[0172] As shown in Figure 16 , Figure 17 , the inner recessed clamping groove 193 is arranged on the interface branch pipe 192 of the drainage device interface 19, and the end of the drainage pipe 20 is provided with the lock catch assembly; when the drainage pipe 20 is plugged with the drainage device interface 19, the clamping block 203 of the lock catch assembly is clamped into the clamping groove 193, so as to realize the reliable connection between the drainage pipe 20 and the drainage device interface 19, and prevent the drainage pipe 20 from being separated from the drainage device interface 19.

[0173] Specifically, the lock catch assembly comprises a pressing block 201, a first fixed ring 202, a clamping block 203, a second spring 204 and a top rod 205.

[0174] As shown in Figure 16 , Figure 17 , the first fixed ring 202 is adhesively fixed at the end of the drainage pipe 20, and the side surface of the first fixed ring 202 is provided with a clamping block mounting groove; the clamping block 203 and the second spring 204 are arranged side by side in the clamping block mounting groove, and the convex round top end of the clamping block 203 protrudes from the inner wall surface of the first fixed ring 202. The pressing block 201 is arranged outside the first fixed ring 202; one end of the top rod 205 is fixedly connected with the clamping block 203, and the other end penetrates through the second spring 204 and the first fixed ring 202 and is fixedly connected with the pressing block 201. One end of the second spring 204 is fixedly connected with the clamping block 203, and the other end abuts against the end surface of the clamping block mounting groove.

[0175] In implementation, the interface branch pipe 192 is inserted with the drainage pipe 20, and the clamping block 203 is extruded into the clamping block mounting groove during the insertion process, and the second spring 204 is compressed; when the clamping block 203 slides in the clamping block mounting groove, the pressing block 201 and the top rod 205 are synchronized with the displacement of the clamping block 203. Until the clamping block 203 is aligned with the clamping groove 193, the clamping block 203 is clamped into the clamping groove 193 under the elastic force of the second spring 204, and the fastening connection of the interface branch pipe 192 and the drainage pipe 20 is realized. When it is necessary to disassemble the drainage pipe 20, the pressing block 201 is only pulled outward, the clamping block 203 is moved out of the clamping groove 193, and the drainage pipe 20 is pulled downward, so that the drainage pipe 20 can be disassembled from the interface branch pipe 192.

[0176] 2) When fastened by the clamping ring assembly:

[0177] As shown in Figure 18 , Figure 19 , a plurality of linear grooves 194 are arranged on the outer surface of the interface branch pipe 192, and a plurality of linear ribs 206 are arranged on the inner wall surface of the drainage pipe 20; when the drainage pipe 20 is inserted with the drainage device interface 19, the linear ribs 206 are clamped into the linear grooves 194. Further, after the drainage pipe 20 is inserted with the drainage device interface 19, the clamping and fixing are performed by the clamping ring assembly.

[0178] Specifically, as shown in Figure 19 , the clamping ring assembly comprises a second fixed ring 207, a clamping ring 208, a third spring 209 and a floating ball 2010.

[0179] The second fixed ring 207 is sleeved on the outside of the drainage pipe 20 and is adhesively fixed with the drainage pipe 20.

The upper end of the drainage pipe 20 is provided with the embeddedly mounted floating ball 2010, and the floating ball 2010 protrudes from the surface of the drainage pipe 20. The floating ball 2010 can float left and right in the drainage pipe 20, and the clamping ring 208 is in extrusion contact with the floating ball 2010 when the third spring 209 is not compressed.

[0180] When the clamping ring 208 contacts the floating ball 2010, the floating ball 2010 is displaced in the axial direction of the drainage pipe 20, and when the clamping ring 208 does not contact the floating ball 2010, the floating ball 2010 can be displaced to the outer surface of the drainage pipe 20. When the drainage pipe 20 is inserted with the interface branch pipe 192, the linear ribs 206 are clamped into the linear grooves 194, and the clamping ring 208 is clamped on the outside of the drainage pipe 20, and the interface branch pipe 192 is pressed by the floating ball 2010, so that the drainage pipe 20 is clamped on the interface branch pipe 192.

[0181] When the drainage tube 20 is installed, the clamping ring 208 is pressed down and the third spring 209 is compressed at the same time, so that the floating ball 2010 is exposed above the clamping ring 208; the drainage tube 20 is inserted into the interface branch pipe 192, and the linear convex rib 206 is clamped into the linear groove 194; the interface branch pipe 192 extrudes the floating ball 2010 outward. When the clamping ring 208 is loosened, the clamping ring 208 is clamped and fixed on the outside of the drainage tube 20 under the elastic force of the third spring 209, and at the same time, the floating ball 2010 is extruded inward, so that the drainage tube 20 and the interface branch pipe 192 are extruded and fixed. When the drainage tube 20 is disassembled, the clamping ring 208 is pressed down and the third spring 209 is compressed at the same time, the clamping ring 208 moves down to below the floating ball 2010, the pressing force on the drainage tube 20 and the interface branch pipe 192 is eliminated, and the drainage tube 20 is pulled down to separate from the interface branch pipe 192.

[0182] Further, the lower end of the clamping ring 208 is provided with a protruding conical ring, the outer surface of the upper end of the drainage tube 20 is provided with a conical surface, and the conical ring of the clamping ring 208 is fitted with the conical surface; when the conical ring is fitted with the conical surface, the clamping ring 208 extrudes the floating ball 2010; as shown in Figure 20 .

[0183] Specifically, the installation mode of the floating ball 2010 is that the side surface of the drainage tube 20 is provided with a ball installation groove, and the diameter of the ball installation groove is greater than the diameter of the floating ball 2010, and the port width of the ball installation groove is less than the diameter of the floating ball; that is, the side surface of the ball installation groove is a circular arc surface, and the central angle corresponding to the circular arc surface is 90°-120°.
