A horizontal cement slurry spraying device and a paver with the device and applications thereof

Abstract

The present invention provides a horizontal mud spraying device and a paver with the device and applications thereof. The cement slurry spraying device mainly includes a cement box. The pipeline in the cement box extends out of the box, surrounds the paver once and returns to the cement box. The pipeline is composed of a pipe and a hose. The hose can be bent according to the spraying position, and the position of the hose on the paver can be adjusted to fit the paver. The cement slurry spraying device can be installed on the paver to spray cement slurry on the roadbed while paving, avoiding cement slurry agglomeration and solidification caused by spraying first and then paving, eliminating the time difference between paving and spraying, and ensuring the adhesion of the base structure. The agitator in the cement box cooperates with the reflux flushing of the reflux pipe to form double stirring. The mechanical rotation stirring of the agitator and the water flow flushing stirring of the reflux pipe continuously stir the cement slurry at the same time, so that the cement slurry maintains uniform mixing characteristics and does not stick and solidify.

Description

Technical Field

[0001] The invention belongs to the field of highway construction equipment, and in particular relates to a horizontal cement slurry spraying device, a paver with the device and applications thereof. Background Art

[0002] With the rapid development of highway construction in the current society, road reconstruction and expansion work occurs from time to time. Under the influence of this national condition, the splicing of new and old roads is particularly important. However, in the process of combining the new and old roadbeds, due to the limitations and differences of practice and various factors, some large and small problems will arise in the process of combining. Therefore, the docking of the new and old roadbeds is a very important task.

[0003] In order to prevent and reduce the gaps and various road surface failures at the junction of the new and old roadbeds, the "reverse excavation construction process" is usually adopted. This construction process requires "cement slurry" with a water-cement mixture ratio to bond and reinforce the joints to increase the overall structural strength between layers. At present, the work of brushing and spraying cement slurry on the roadbed steps is done manually, which is very inefficient and has problems such as uneven brushing, which brings certain troubles to the construction progress.

[0004] At present, cement slurry spraying machines have been used to replace manual spraying, such as the application document with application number 201820073938.X, which mainly realizes the function of spraying cement slurry through various structural combinations on the automobile body.

[0005] However, the above device has the following problems:

[0006] (1) It must be independently towed by a tire dump truck, which is a special vehicle for special use. The road trench depth of the "reverse excavation construction process" is about 670mm, and it is inconvenient for a tire dump sprayer to go up and down the road trench;

[0007] (2) There is a time lag after the dump truck sprays the cement slurry. When the paver spreads the cement slurry, it agglomerates and solidifies early, and the characteristics of the cement slurry cannot be well guaranteed. This affects the adhesion between the base structures and the structural strength of the roadbed. Summary of the invention

[0008] The purpose of an embodiment of the present invention is to provide a horizontal cement slurry spraying device and a paver having the device and applications thereof. The first purpose is to solve the problem that the existing cement slurry spraying device must be independently towed by a truck, which makes it inconvenient to go up and down the road trough; the second purpose is to solve the problem that the existing spraying device and the paver cannot perform paving work synchronously, and there is a time difference that causes poor adhesion between the base structure and low structural strength.

[0070] No spraying state: Figure 4 As shown, cement is added into cement tank 1 through feeding window 105, and clean water is added into cement tank 1 through water adding window 106, valves III 1003, V 1005, IX 1009 and XII 1012 are closed, other valves are opened, and the paver is started. Agitator 3 rotates first and rotates counterclockwise to stir the cement slurry mixture, and screw pump 2 is started again. The cement slurry is sucked into the pump body by screw pump 2, passes through pipe No. 1 901 and pipe No. 2 902 in turn, and is separated at the connection between pipe No. 2 902 and pipe No. 3 903. There are two routes, one route enters the cement tank 1 through valve No. Ⅰ 1001 and is discharged through the first return pipe 1301 to flush the bottom of the cement tank 1, and the other route enters the cement tank 1 through pipeline No. 3 903, pipeline No. 5 905, pipeline No. 6 906, pipeline No. 4 904, pipeline No. 7 907, pipeline No. 8 908, valve No. Ⅹ 1010 and is discharged through the second return pipe 1302 to flush the bottom of the cement tank 1. The two return pipes return and flush the bottom of the tank body, forming a double mixing with the agitator 3, and the cycle continues until the cement slurry in the cement tank 1 is evenly mixed;

[0071] Front spraying work and side spraying work at the same time: Figure 5 As shown, valves III, IV, VIII, and XII are closed, other valves are opened, and the paver is started. Agitator 3 rotates first and rotates counterclockwise to stir the cement slurry mixture. Screw pump 2 is started again, and the cement slurry is sucked into the pump body by screw pump 2, and passes through pipeline No. 1 901 and pipeline No. 2 902 in sequence. At the connection between pipeline No. 2 902 and pipeline No. 3 903, it is divided into two paths. One path enters cement tank 1 through valve No. 1001 and is discharged through first reflux pipe 1301 to flush the bottom of cement tank 1. The other path flows through pipeline No. 3 903, pipeline No. 5 905, The sixth pipe 906, the first hose 1201, the first spray pipe 1101, the second hose 1202, the second spray pipe 1102, the third hose 1203, the third spray pipe 1103, the fourth hose 1204, the seventh pipe 907, the eighth pipe 908, and the X valve 1010 enter the cement tank 1 and are discharged through the second return pipe 1302 to flush the bottom of the cement tank 1, and the circulation is continuous, ensuring that the first spray pipe 1101 and the third spray pipe 1103 respectively spray cement slurry uniformly and continuously on the adjacent side roadbed 8, and the second spray pipe 1102 sprays cement slurry uniformly and continuously on the middle roadbed 7;

[0072] Front spray does not work while side spray works: Figure 6 As shown, valves III, IV, VI, VII, and XII are closed, other valves are opened, and the paver is started. Agitator 3 rotates first and rotates counterclockwise to stir the cement slurry mixture. Screw pump 2 is started again, and the cement slurry is sucked into the pump body by screw pump 2, and passes through pipeline No. 1 901 and pipeline No. 2 902 in sequence. At the connection between pipeline No. 2 902 and pipeline No. 3 903, it is divided into two paths. One path enters cement tank 1 through valve No. 1001 and is discharged through the first reflux pipe 1301 to flush the bottom of cement tank 1. The other path The cement slurry flows sequentially through the No. 3 pipe 903, the No. 5 pipe 905, the No. 6 pipe 906, the No. 1 hose 1201, the first spray pipe 1101, the No. 2 hose 1202, the No. 10 pipe 910, the No. 3 hose 1203, the third spray pipe 1103, the No. 4 hose 1204, the No. 7 pipe 907, the No. 8 pipe 908, the No. 10 valve 1010, enters the cement box 1, and is discharged through the second return pipe 1302 to flush the bottom of the cement box 1, and circulates continuously to ensure that the first spray pipe 1101 and the third spray pipe 1103 respectively spray cement slurry uniformly and uninterruptedly on the adjacent side roadbed 8;

[0073] Cleaning state: add clean water into the cement box 1, open all valves, circulate the clean water in all pipes and spray the clean water through the first spray pipe 1101, the second spray pipe 1102, and the third spray pipe 1103 to flush the cement box 1 and the pipes, and circulate multiple times until the cleaning is completed.

[0074] It should be noted that the screw pump 2 does not need to be equipped with a separate power device, but the power device of the paver is used to provide power for the screw pump 2 as a power source for pumping cement slurry.

[0075] All valves can be used together to adjust the cement slurry injection flow rate, adjust the flow direction of the cement slurry and the pipes it passes through, etc.

[0076] In particular, a certain proportion (the proportion is adjusted according to on-site needs) of cement and clean water needs to be manually poured into the cement box 1 in advance, and then sprayed after being evenly mixed in the cement box 1. Specifically, the cement slurry of the cement slurry spraying device is cyclically sprayed, a part of the cement slurry is sprayed on the roadbed, and the remaining part of the cement slurry is returned to the cement box 1, and then sucked and sprayed out by the screw pump 2 after stirring, and the cycle is continuously carried out. The remaining amount of cement slurry in the cement box 1 is observed, and cement slurry is added in time as needed to avoid uneven spraying caused by insufficient remaining amount.

[0077] In this embodiment, the cement slurry spraying device is suspended on the paver, which is convenient for disassembly and installation, and the cement spraying function is carried out simultaneously with the pavement paving work, ensuring the interlayer adhesion between the paving material and the cement slurry, avoiding the cement slurry from clumping and solidifying caused by spraying first and then paving, and eliminating the time difference between paving and spraying.

[0078] Second implementation method:

[0079] Different from the first embodiment, Figure 1 or Figure 4 or Figure 5 or Figure 6 In this embodiment, two return pipes are added. Specifically, the No. 3 pipe 903 and the No. 5 pipe 905 are connected via a three-way valve. The No. II valve 1002 is installed at the third outlet of the three-way valve. The No. II valve 1002 is connected to the third return pipe 1303 in the cement box 1.

[0081] The working principle of the cement slurry spraying device in this embodiment is as follows:

[0082] No spraying state: Figure 4 As shown, cement is added into cement tank 1 through feeding window 105, and clean water is added into cement tank 1 through water adding window 106, valves III 1003, V 1005, IX 1009 and XII 1012 are closed, other valves are opened, and the paver is started. Agitator 3 rotates first and rotates counterclockwise to stir the cement slurry mixture, screw pump 2 is started again, and the cement slurry is sucked into the pump body by screw pump 2, passes through pipeline No. 1 901 and pipeline No. 2 902 in turn, and is divided into two paths at the connection between pipeline No. 2 902 and pipeline No. 3 903. One path enters cement tank 1 through valve No. 1001 and is discharged through the first reflux pipe 1301 to flush the bottom of cement tank 1, and the other path passes through pipeline No. 3 After 903, it is divided into two paths. One path enters the cement tank 1 through the valve No. II 1002 and is discharged through the third return pipe 1303 to flush the bottom of the cement tank 1. The other path flows through the pipeline No. 5 905, the pipeline No. 6 906, the pipeline No. 4 904, the pipeline No. 7 907 and the pipeline No. 8 908 in sequence and then is divided into two paths. One path enters the cement tank 1 through the valve No. X 1010 and is discharged through the second return pipe 1302 to flush the bottom of the cement tank 1. The other path passes through the pipeline No. 9 909 and the valve No. XI 1011 in sequence and then is discharged through the fourth return pipe 1304 to flush the bottom of the cement tank 1. The four return pipes return and flush the bottom of the tank body, forming a double mixing with the agitator 3, and the cycle continues until the cement slurry in the cement tank 1 is evenly mixed.

[0083] Front spraying work and side spraying work at the same time: Figure 5 As shown, valves III, IV, VIII, and XII are closed, other valves are opened, and the paver is started. Agitator 3 rotates first and rotates counterclockwise to stir the cement slurry mixture. Screw pump 2 is started again, and the cement slurry is sucked into the pump body by screw pump 2, passes through pipeline No. 1 901 and pipeline No. 2 902 in sequence, and is divided into two paths at the connection between pipeline No. 2 902 and pipeline No. 3 903. One path enters cement tank 1 through valve No. 1001 and is discharged through the first return pipe 1301 to flush the bottom of cement tank 1.

One route enters the cement box 1 through the No. 10 valve 1010 and is discharged through the second return pipe 1302 to flush the bottom of the cement box 1. The other route passes through the No. 9 pipe 909 and the No. 11 valve 1011 in turn and is discharged through the fourth return pipe 1304 to flush the bottom of the cement box 1. The cycle continues, ensuring that the first spraying pipe 1101 and the third spraying pipe 1103 respectively spray cement slurry uniformly and continuously on the adjacent side roadbed 8, and at the same time, the second spraying pipe 1102 sprays cement slurry uniformly and continuously on the middle roadbed 7.

[0084] Front spray does not work while side spray works: Figure 6As shown, valves III, IV, VI, VII, and XII are closed, other valves are opened, and the paver is started. Agitator 3 rotates first and rotates counterclockwise to stir the cement slurry mixture. Screw pump 2 is started again, and the cement slurry is sucked into the pump body by screw pump 2, passes through pipeline No. 1 901 and pipeline No. 2 902 in sequence, and is divided into two paths at the connection between pipeline No. 2 902 and pipeline No. 3 903. One path enters cement tank 1 through valve No. 1001 and is discharged through the first return pipe 1301 to flush the bottom of cement tank 1. The other path is divided into two paths after passing through pipeline No. 3 903. One path enters cement tank 1 through valve No. 2 1002 and is discharged through the third return pipe 1303 to flush the cement tank. 1, and the other path flows through the No. 5 pipeline 905, the No. 6 pipeline 906, the No. 1 hose 1201, the first spraying pipe 1101, the No. 2 hose 1202, the No. 10 pipeline 910, the No. 3 hose 1203, the third spraying pipe 1103, the No. 4 hose 1204, the No. 7 pipeline 907, and the No. 8 pipeline 908, and then is divided into two paths. One path enters the cement tank 1 through the No. Ⅹ valve 1010 and is discharged through the second return pipe 1302 to flush the bottom of the cement tank 1, and the other path passes through the No. 9 pipeline 909, the No. Ⅺ valve 1011, and then is discharged through the fourth return pipe 1304 to flush the bottom of the cement tank 1, and the cycle continues, ensuring that the first spraying pipe 1101 and the third spraying pipe 1103 respectively spray cement slurry uniformly and uninterruptedly on the adjacent side roadbed 8;

[0085] Cleaning state: add clean water into the cement box 1, open all valves, circulate the clean water in all pipes and spray the clean water through the first spray pipe 1101, the second spray pipe 1102, and the third spray pipe 1103 to flush the cement box 1 and the pipes, and circulate multiple times until the cleaning is completed.

[0086] In this embodiment, the horizontal cement slurry spraying device has four reflux pipes. The mechanical rotation stirring of the agitator and the water flushing stirring of the four reflux pipes continuously stir the cement slurry simultaneously, so that the cement slurry maintains uniform mixing characteristics and does not stick and solidify.

[0087] Third embodiment:

[0088] Based on the second implementation mode, Figure 1 or Figure 4 or Figure 5 or Figure 6 The third return pipe 1303 and the fourth return pipe 1304 have the same structure and are arranged opposite to each other. They are both straight pipes. One end of the straight pipe is connected to valve No. Ⅱ 1002 or valve No. Ⅺ 1011, and the other end penetrates the wall of the cement box 1 and extends into the cement box 1 and is close to the bottom of the cement box 1.

[0089] In order to enhance the flushing pressure, the first return pipe 1301 and the second return pipe 1302 have the same structure and are arranged opposite to each other, both of which are composed of a U-shaped pipe and a straight pipe, wherein the opening end of the U-shaped pipe is a flat mouth and is inclined toward the bottom of the cement box 1, and the sealing end opposite to the opening end is connected with the straight pipe, and the straight pipe passes through the wall of the cement box 1 and is connected with valve No. Ⅰ 1001 or valve No. Ⅹ 1010.

[0090] Reference Figure 1 or Figure 4 or Figure 5 or Figure 6 The U-shaped flat ejection ports of the first return pipe 1301 and the second return pipe 1302 cooperate with the straight pipes of the third return pipe 1303 and the fourth return pipe 1304, which can increase the flow rate on the one hand and increase the injection pressure of the cement slurry on the other hand, thereby forming a vortex with the stirring of the agitator 3 and improving the uniformity of the stirring.

[0091] The bottom of the cement box 1 consists of three sections, namely a horizontal section 101 in the center, and slope sections 102 located on both sides of the horizontal section 101 and symmetrically distributed about the horizontal section 101. The height of the slope section 102 gradually increases from the center to the side wall. The through opening 104 of the cement box 1 is opened in the horizontal section 101, and the horizontal section 101 is also provided with a sewage outlet 103.

[0092] The horizontal section 101 is the low-lying part of the cement box 1 . The cement slurry in the cement box 1 slides down along the box wall or the sloped section 102 to the horizontal section 101 , is aggregated and mixed in the horizontal section 101 , and then enters the screw pump 2 through the through port 104 .

[0093] The above-mentioned design of the cement box 1 can prevent cement slurry from accumulating at the corners or the box walls of the cement box 1, thereby improving the utilization efficiency of the cement slurry.

[0094] In order to facilitate the addition of cement and water, the top cover of the cement box 1 is provided with a feeding window 105 and a water adding window 106 , both of which are paved with screens, and the diameter of the feeding window 105 is larger than that of the water adding window 106 .

[0095] It should be noted that the water adding window 106 can also be used as an observation port to observe the remaining amount of cement slurry and replenish cement or clean water in time.

[0100] The above is a preferred arrangement of the suspension bracket 5 and the mounting base 6, but is not limited thereto. Any structure that can suspend the cement slurry spraying device on the paver can be used. It is worth mentioning that the cement slurry spraying device can also be detachably installed on the paver or fixed to the paver or plugged into the paver. In order to facilitate installation and disassembly, the present embodiment preferably adopts a hanging method.

[0101] In order to facilitate the addition of cement and clean water, at least two escalators are provided on the side of the cement box 1 , one of which is close to the material adding window 105 , and the other is close to the water adding window 106 .

The agitator in the cement box cooperates with the reflux flushing of the reflux pipe to form double stirring. The mechanical rotation stirring of the agitator and the water flow flushing stirring of the reflux pipe continuously stir the cement slurry at the same time, so that the cement slurry maintains uniform mixing characteristics and does not stick and solidify.

The other path passes through the No. 3 pipe (9 03) and then divided into two paths, one path enters the cement box (1) through valve No. II (1002) and is discharged through the third return pipe (1303) to flush the bottom of the cement box (1), and the other path flows through pipe No. 5 (905), pipe No. 6 (906), pipe No. 4 (904), pipe No. 7 (907) and pipe No. 8 (908) in sequence and then divided into two paths, one path enters the cement box (1) through valve No. X (1010) and is discharged through the second return pipe (1302) to flush the bottom of the cement box (1), and the other path flows through pipe No. 9 (909), valve No. XI (1011) in sequence and then is discharged through the fourth return pipe (1304) to flush the bottom of the cement box (1). The four return pipes return and flush the bottom of the box body, forming a double mixing with the agitator (3), and the cycle continues until the cement slurry in the cement box (1) is evenly mixed; S002.Working status S201. Front spraying while side spraying Close valves III (1003), IV (1004), VIII (1008) and XII (1012), open other valves, start the paver, and the agitator (3) rotates first and rotates counterclockwise to stir the cement slurry mixture. The screw pump (2) is then started, and the cement slurry is sucked into the pump body by the screw pump (2), and passes through pipes No. 1 (901) and No. 2 (902) in sequence, and then passes through pipes No. 2 (902) and No. 3 ( The cement tank (1) is divided into two paths at the connection point of No.

903. One path enters the cement tank (1) through the No. Ⅰ valve (1001) and is discharged through the first return pipe (1301) to flush the bottom of the cement tank (1). The other path is divided into two paths after passing through the No. 3 pipe (903). One path enters the cement tank (1) through the No. Ⅱ valve (1002) and is discharged through the third return pipe (1303) to flush the bottom of the cement tank (1). The other path flows through the No. 5 pipe (905), the No. 6 pipe ( The flushing water is then divided into two paths, one of which enters the cement box (1) through the No. X valve (1010) and is discharged through the second return pipe (1302). The bottom of the mud box (1), and the other route is discharged through the ninth pipeline (909), the Ⅺ valve (1011) and the fourth return pipe (1304) to flush the bottom of the cement box (1), and the cycle continues, ensuring that the first spraying pipe (1101) and the third spraying pipe (1103) respectively spray cement slurry uniformly and continuously on the adjacent side roadbed (8), and the second spraying pipe (1102) sprays cement slurry uniformly and continuously on the middle roadbed (7); S202. Front spray does not work while side spray works Close valves III (1003), IV (1004), VI (1006), VII (1007) and XII (1012), open other valves, start the paver, and the agitator (3) rotates first and rotates counterclockwise to stir the cement slurry mixture. The screw pump (2) is then started, and the cement slurry is sucked into the pump body by the screw pump (2), passes through pipe No. 1 (901) and pipe No. 2 (902) in sequence, and is divided into two paths at the connection between pipe No. 2 (902) and pipe No. 3 (903). One path enters the cement tank (1) through valve No. 1 (1001) and is discharged through the first return pipe (1301) to flush the bottom of the cement tank (1). The other path passes through pipe No. 3 (903) and is divided into two paths. One path enters the cement tank (1) through valve No. 2 (1002) and is discharged through the third return pipe (1303) to flush the bottom of the cement tank (1). The other path flows sequentially through the fifth pipeline (905), the sixth pipeline (906), the first hose (1201), the first spraying pipe (1101), the second hose (1202), the tenth pipeline (910), the third hose (1203), the third spraying pipe (1103), the fourth hose (1204), the seventh pipeline (907), and the eighth pipeline (908), and then is divided into two paths. One path enters the cement box (1) through the No. X valve (1010) and is discharged through the second return pipe (1302) to flush the bottom of the cement box (1). The other path flows sequentially through the No. 9 pipeline (909), the No. XI valve (1011), and then is discharged through the fourth return pipe (1304) to flush the bottom of the cement box (1). The cycle continues, ensuring that the first spraying pipe (1101) and the third spraying pipe (1103) respectively spray cement slurry uniformly and continuously on the adjacent side roadbed (8); S003. Cleaning status Add clean water into the cement box (1), open all valves, and allow the clean water to circulate in all pipes and spray through the first spray pipe (1101), the second spray pipe (1102), and the third spray pipe (1103) to flush the cement box (1) and the pipes. Repeat the cycle several times until the cleaning is completed.
