Description

Technical Field

[0001] The invention belongs to the technical field of concrete wet spraying, in particular to a foundation reinforcement concrete wet spraying device and a construction method. Background Art

[0002] Wet concrete spraying is a construction method that uses a spraying machine to load pre-mixed cement, sand, gravel and a certain amount of accelerator into the sprayer, use high-pressure air to send them to the nozzle and mix them with water, and then spray them onto the surface of rock or concrete at a very high speed.

[0003] In bridge reinforcement, wet shotcrete can be used to repair and reinforce cracks, damage and weak parts of bridges, and improve the bearing capacity and durability of bridges. It should be noted that when carrying out wet shotcrete reinforcement, the construction process and quality need to be strictly controlled to ensure the reinforcement effect and bridge safety.

[0004] In the prior art, when feeding the wet spraying machine, the cement in the tank truck is generally poured slowly onto the sieve plate of the discharge barrel, and the large hard impurities are filtered out through the sieve plate, and then the cement enters the discharge barrel to spray out the liquid concrete through high pressure. However, there are the following problems: First, the tank truck and the wet spraying machine are generally fixed (inconvenient to move). When the tank truck is used to discharge the material onto the sieve plate, the position is often fixed. Because the concrete is liquid and viscous, it is not easy to pass through the sieve plate. Although there is a vibrator for vibrating the discharge, overflow often occurs (the material is not discharged in time at the sieve plate, and the material piles up thicker and thicker, and workers need to spread it manually with tools). Moreover, because the discharge position is fixed, only a part of the sieve plate is used, and the utilization rate is low. Second, when hard impurities appear, they cannot be removed in the first time, and workers are also required to take care of them to prevent large pieces of hard impurities from accumulating on the sieve plate and affecting the discharge rate.

[0005] To this end, the present invention provides a foundation reinforcement concrete wet spraying equipment and a construction method. Summary of the invention

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 10As shown, a foundation reinforcement concrete wet spraying equipment described in an embodiment of the present invention includes a body 1 and a discharge barrel 11; the discharge barrel 11 is installed on the body 1; a spray pipe 12 is fixedly connected to the side wall of the discharge barrel 11 away from the body 1; the opening at the top of the discharge barrel 11 is inclined downward, and the spray pipe 12 is located at the lower end of the opening of the discharge barrel 11; the top opening of the discharge barrel 11 is square or isosceles trapezoidal; a fixed inclined plate 13 is fixedly connected to the side wall of the high end of the opening of the discharge barrel 11; a sieve plate 14 is rotatably connected to the side walls on both sides of the lower end of the top opening of the discharge barrel 11 through a rotating column; a placement block is fixedly connected to the side wall of the discharge barrel 11 away from the spray pipe 12; the sieve plate 14 is far away One end away from the rotating column is placed on the placement block; the planes where the sieve plate 14 and the opening of the discharge barrel 11 are located are parallel to each other; a trapezoidal plate 15 is fixedly connected to the top of the sieve plate 14 near the fixed inclined plate 13, and a pneumatic vibrator 16 is fixedly connected to the top of the trapezoidal plate 15; an upper fixed plate 2 and a lower fixed plate 21 are placed on the sieve plate 14, and the upper fixed plate 2 is mounted on the trapezoidal plate 15 by bolts, and the lower fixed plate 21 is mounted at the bottom of the sieve plate 14 by bolts; two pairs of symmetrically distributed first rotating shafts 22 are rotatably connected between the upper fixed plate 2 and the lower fixed plate 21; the first rotating shaft 22 and the sieve plate 14 are arranged parallel to each other; the first rotating shaft 22 is fixedly connected to the positions near both ends A pair of sprockets 23, the sprockets 23 on the two adjacent first rotating shafts 22 are driven by a chain 24; a group of scraper plates 25 are fixedly connected between the two chains 24 on each side; the first rotating shaft 22 is driven by an air motor 26, and the air motor 26 is fixedly connected to the upper fixed plate 2; when the scraper plates 25 are driven to rotate by the chain 24, the bottom end of the scraper plates 25 does not contact the screen plate 14; a first inclined surface 27 is provided at the bottom end of the scraper plates 25; in the prior art, when feeding the wet spraying machine, the cement in the tank truck is generally slowly poured onto the screen plate 14 of the discharge barrel 11, and the large pieces of hard impurities are filtered out by the screen plate 14, and then enter the discharge barrel 11, and the liquid mixture is mixed by high pressure. Concrete is sprayed out, but there are the following problems: first, tank trucks and wet spraying machines are generally fixed (inconvenient to move). When the tank truck is used to discharge the material on the screen plate 14, the position is often fixed. Because the concrete is liquid and viscous, it is not easy to pass through the screen plate 14. Although there is a vibrator to vibrate and discharge the material, overflow often occurs (the material is not discharged in time at the screen plate 14, and the material piles up thicker and thicker, and workers need to spread it manually with tools). In addition, due to the fixed discharge position, only a part of the screen plate 14 is used, and the utilization rate is low; second, when hard impurities appear, they cannot be removed in the first time, and workers are also required to take care of them to prevent large pieces of hard impurities from accumulating on the screen plate 14 and affecting the discharge rate;For this reason, when the present invention is working, the sprocket wheels 23 on the two sets of first rotating shafts 22 are used to drive the scraper plates 25 to move through the transmission of the chains 24, so that the concrete in the middle of the material is spread to both sides. After the concrete is spread to both sides, the utilization rate of the screen plate 14 can be increased, and the excessive accumulation of the material discharge position can be avoided. At the same time, the openings of the screen plate 14 and the discharge barrel 11 are both inclined downward, so that the concrete can flow downward while spreading to both sides, further increasing the coverage of the screen plate 14 to ensure the material discharge rate. At the same time, the two sets of scraper plates 25 are from the screen plate 1 4 moves to both sides, which can push the large hard impurities of the material to both sides to avoid affecting the material discharge of the sieve plate 14, and can also accumulate the hard impurities to both sides for collection operation; at the same time, the upper fixing plate 2 and the lower fixing plate 21 provided in the present invention are both bolt-mounted, and the upper fixing plate 2 and the lower fixing plate 21 can be disassembled as a whole. When corresponding to different concrete materials, they can be selectively installed or disassembled. At the same time, the detachable installation of the upper fixing plate 2 and the lower fixing plate 21 does not affect the subsequent opening of the sieve plate 14 to clean the inside of the material discharge barrel 11. ;

[0037] The scraper plate 25 is provided with a first slide groove 31 on its side wall; a slide plate 32 is slidably connected in the first slide groove 31; an elastic telescopic rod 33 is fixedly connected to the side wall of the slide plate 32 close to the lower fixed plate 21, and the elastic telescopic rod 33 is fixedly connected to the side wall of the first slide groove 31; a group of partitions 3 are provided on the side wall of the slide plate 32, and a triangular surface 34 is provided on the side wall of the partition 3 away from the slide plate 32; the slide plate 32 moves back and forth through the circulating power member; when working, the partition 3 is used to slow down the downward flow speed of the concrete after it is spread from the middle to both sides, so as to further increase the material discharge rate of the screen plate 14, and at the same time, the scraper plate 25 When the partition 3 is driven to move from the middle to both sides, the partition 3 will be driven to move up and down multiple times through the circulating power parts. The partition 3 moves upward, which can make the concrete material between adjacent partitions 3 rise a certain flow distance. The partition 3 moves downward to allow the concrete material in the partition 3 to flow down between adjacent partitions 3 (to prevent the concrete between adjacent partitions 3 from flowing down from the openings between adjacent partitions 3. The transmission speed of the chain 24 is slow, and the concrete material is easily thrown out if it is too fast). The reciprocating circulation of the partition 3 can further slow down the overall downward speed of the concrete, and further ensure the unloading rate of the screen plate 14.

[0038] The circulating power part includes a semi-elliptical through groove 35; a pair of symmetrically distributed semi-elliptical through grooves 35 are opened on the upper fixed plate 2, and the upper fixed plate 2 cut off by the semi-elliptical through groove 35 is fixedly connected to the outer wall of the upper fixed plate 2 by a U-shaped rod 36; a sliding rod 37 is fixedly connected to the side wall of the slide plate 32 close to the upper fixed plate 2, and the sliding rod 37 extends out of the upper fixed plate 2 and slides in the semi-elliptical through groove 35; a pushing column 38 is fixedly connected to the end of the sliding rod 37 extending out of the upper fixed plate 2, and the pushing column 38 is perpendicular to the sliding rod 37; a group of right-angled trapezoidal blocks 39 are fixedly connected to the side wall of the upper fixed plate 2 away from the lower fixed plate 21, and the group of right-angled trapezoidal blocks 39 are symmetrically distributed about the straight groove of the semi-elliptical through groove 35; when the sliding rod 37 moves following the scraper plate 25, the pushing column 38 is pushed When the moving column 38 and the right-angled trapezoidal block 39 are in contact and working, when the chain 24 is driving, the scraper plate 25 and the partition plate 3 move in the same direction and at the same speed. At this time, the sliding rod 37 drives the pushing column 38 to move in the straight groove of the semi-elliptical through groove 35. The pushing column 38 will first move through the inclined surface of the right-angled trapezoidal block 39, and then drive the slide plate 32 to move through the sliding rod 37, and then drive a group of partition plates 3 upward. When the pushing column 38 slides down through the right-angled surface of the right-angled trapezoidal block 39, the slide plate 32 is restored to its original position through the elastic telescopic rod 33, and then a group of partition plates 3 are restored to their original position. Because multiple groups of right-angled trapezoidal blocks 39 are arranged, the partition plates 3 are allowed to move up and down cyclically when the scraper plate 25 moves from the middle of the screen plate 14 to both sides, thereby slowing down the downstream flow rate of the concrete and ensuring the unloading rate.

[0039] A group of corrugated grooves 4 are provided at the top of the right-angled trapezoidal block 39; the pushing column 38 is a circular column; when working, when the pushing column 38 rises from the inclined surface of the right-angled trapezoidal block 39 to the top of the right-angled trapezoidal block 39, it will pass through the corrugated groove 4, and the pushing column 38 will move up and down on the corrugated groove 4 to drive the partition 3 to tap the concrete located between the adjacent partitions 3, which can speed up the feeding rate.

[0040] A group of second slide grooves 41 are provided on the bottom of the first slide groove 31; a slider 42 is fixedly connected to the side wall of the second slide groove 41 near the upper fixed plate 2 through a stabilizing spring 43; the slider 42 is slidably connected in the second slide groove 41, and the slider 42 is fixedly connected to the side wall of the slide plate 32; a ball 44 is fixedly connected to the side wall of the slider 42 near the lower fixed plate 21; when working, there are sliders 42 and ball 44, when the pushing column 38 on the sliding rod 37 does not contact the right-angled trapezoidal block 39, at this time, the slider 42, under the action of the spring force of the stabilizing spring 43, allows the ball 44 to be tightly attached to the side wall of the second slide groove 41, at this time, the slide plate 32, the sliding rod 37 and the pushing column 38 are all in a stable state, so after the sliding rod 37 is separated from the semi-elliptical groove 35, It can stably enter the semi-elliptical groove 35 again from the other end of the semi-elliptical groove 35. At the same time, when the push column 38 falls through the right-angled side of the right-angled trapezoidal block 39, it is in an instantaneous drop. At this time, under the action of the spring force of the stabilizing spring 43, it can drive the ball 44 on the slider 42 to collide with the side wall of the second slide groove 41 at high speed. At this time, the partition 3 and the scraper plate 25 can be vibrated to facilitate shaking off the materials attached to them, and to increase the overall vibration force and facilitate the unloading of the screen plate 14 (the pneumatic vibrator 16 can vibrate, but mainly the screen plate 14. The vibration here is mainly the partition 3 and the scraper plate 25. In particular, when the upper fixed plate 2 and the lower fixed plate 21 are removed for cleaning, the vibration on the partition 3 and the scraper plate 25 can facilitate cleaning).

[0041] A group of limit blocks 51 are fixedly connected to the side wall of the slide plate 32 away from the slide block 42; a third slide groove 5 is opened on the side wall of the partition 3; the limit block 51 is slidably connected in the third slide groove 5, and the limit block 51 is square; a threaded rod 53 is rotatably connected between the upper and lower side walls of the third slide groove 5, and the threaded rod 53 and the limit block 51 are threadedly connected; the top of the threaded rod 53 extends out of the top of the partition 3; when working, the distance from the bottom end of the partition 3 to the bottom end of the scraper plate 25 can be adjusted by rotating the threaded rod 53, so as to be suitable for concrete materials of different compositions (different compositions, different viscosities, and different material discharge rates on the screen plate 14).

[0042] A U-shaped enclosure 6 is fixedly connected to the outer side wall of the opening of the unloading barrel 11; the fixed inclined plate 13 is located at the opening of the U-shaped enclosure 6; a first inclined surface 61 is provided on the side wall of the U-shaped enclosure 6 away from the fixed inclined plate 13; a pair of first grooves 62 symmetrically distributed about the first inclined surface 61 are provided on the side wall of the U-shaped enclosure 6 away from the fixed inclined plate 13; a T-shaped block 63 is fixedly connected to the bottom of the first groove 62 through a spring; both sides of the T-shaped block 63 are retractable; when the T-shaped block 63 is squeezed and moved toward the bottom of the first groove 62, an alarm will be issued; when working, the scraper plate 25 and the partition plate 3 drive the concrete to be removed from the sieve plate 14 When the sieve 14 is spread out to both sides, once it encounters concrete or hard impurities that cannot be discharged after spreading out, it will be pushed to both sides of the U-shaped enclosure 6, and then the material will flow down as a whole, squeezing the T-shaped block 63. When the T-shaped block 63 is squeezed, it will alarm through the alarm part, thereby reminding the workers to clean the sieve plate 14 or slow down the unloading speed of the tank truck, etc., so that timely notification can be given to avoid overflow or accumulation of impurities. At the same time, because the opening of the discharge barrel 11 is square and isosceles trapezoidal, when it is an isosceles trapezoidal, the two sides of the T-shaped block 63 are contractile to avoid jamming. The setting of the first inclined surface 61 can facilitate the opening of the sieve plate 14 at an inclination angle greater than ninety degrees.

[0043] The alarm component includes a positive pole 64 and a negative pole 65; warning lights 66 are fixedly connected to the side walls of both sides of the discharge barrel 11; a negative pole 65 is fixedly connected to the middle of the bottom of the first groove 62; a positive pole 64 is fixedly connected to the side wall of the T-shaped block 63 close to the first groove 62; when the positive pole 64 and the negative pole 65 fit together, the warning light 66 alarms; during operation; when the T-shaped block 63 is squeezed, the positive pole 64 is pushed to move, and when the positive pole 64 and the negative pole 65 fit together, the warning light 66 alarms and notifies in time.

[0044] A pair of pneumatic motors 26 drive the connected first rotating shaft 22 to rotate in opposite directions and at the same speed; when the two groups of scraper plates 25 on the two pairs of the first rotating shafts 22 follow the chain 24 to rotate, the two groups of scraper plates 25 rotate alternately; when working, a pair of pneumatic motors 26 drive the connected first rotating shafts 22 to rotate in opposite directions and at the same speed, that is, the scraper plates 25 are spread out from the middle of the screen plate 14 to both sides, and at the same time, the scraper plates 25 are rotated alternately (that is, the two will never meet), so as to increase the scraping range of the scraper plates 25 and ensure the subsequent spreading effect (the above-mentioned semi-elliptical through grooves 35 are set instead of elliptical through grooves) The same reason).

[0045] A construction method of a foundation reinforcement concrete wet spraying device, the method adopts the above-mentioned foundation reinforcement concrete wet spraying device, and the steps of the method are as follows:

[0046] S1: Pour concrete into the upper middle part of the sieve plate 14 of the discharge barrel 11 through a tank truck, then start the pneumatic vibrator 16 and the pneumatic motor 26 to drive the sieve plate 14 to vibrate and the scraper plate 25 to rotate, so that the scraper plate 25 spreads the concrete material from the middle of the sieve plate 14 to both sides;

[0047] S2: During the spreading process, the scraper plate 25 drives the partition plate 3 to move back and forth through the circulating power member, slowing down the downflow rate of the concrete on the screen plate 14;

[0048] S3: At the same time, the scraper plate 25 pushes the hard and large impurities from the middle of the sieve plate 14 to the two sides of the sieve plate 14, so as to facilitate the collection operation.

[0049] Working principle: two groups of sprockets 23 on the first rotating shaft 22 are used to drive the scraper plate 25 to move through the transmission of the chain 24, so that the concrete in the middle of the material discharge is spread to both sides. After the concrete is spread to both sides, the utilization rate of the screen plate 14 can be increased, and the excessive accumulation of the material discharge position can be avoided. At the same time, the screen plate 14 and the opening of the discharge barrel 11 are tilted downward, so that the concrete can flow downward while spreading to both sides, further increasing the coverage of the screen plate 14 to ensure the material discharge rate. At the same time, the two groups of scraper plates 25 move from the middle of the screen plate 14 to both sides, which can push the large hard impurities of the material discharge to both sides to avoid affecting the material discharge of the screen plate 14, and also The hard impurities can be accumulated on both sides for collection operation; at the same time, the upper fixed plate 2 and the lower fixed plate 21 provided in the present invention are both bolt-mounted, and the upper fixed plate 2 and the lower fixed plate 21 can be disassembled as a whole. When corresponding to different concrete materials, they can be selectively installed or disassembled. At the same time, the detachable installation of the upper fixed plate 2 and the lower fixed plate 21 does not affect the subsequent opening of the sieve plate 14 to clean the inside of the discharge barrel 11; when the chain 24 is driven, the scraper plate 25 and the partition plate 3 move in the same direction and at the same speed. At this time, the sliding rod 37 drives the push column 38 to move in the straight groove of the semi-elliptical through groove 35, and the push column 38 will first move through the inclined surface of the right-angled trapezoidal block 39, and then move. The sliding plate 32 is driven to move by the sliding rod 37, thereby driving a group of partitions 3 upward. When the pushing column 38 slides down through the right-angled surface of the right-angled trapezoidal block 39, the sliding plate 32 is restored to its original position by the elastic telescopic rod 33, thereby allowing a group of partitions 3 to return to their original position. Because the right-angled trapezoidal blocks 39 are provided in multiple groups, the partitions 3 are allowed to move up and down cyclically when the scraper plate 25 moves from the middle of the sieve plate 14 to both sides, thereby slowing down the downflow rate of the concrete and ensuring the feeding rate; a sliding block 42 and a ball 44 are provided. When the pushing column 38 on the sliding rod 37 is not in contact with the right-angled trapezoidal block 39, the sliding block 42, under the action of the spring force of the stabilizing spring 43, allows the ball 44 to move upward. 4 is closely attached to the side wall of the second chute 41. At this time, the slide plate 32, the sliding rod 37 and the pushing column 38 are all in a stable state. Therefore, after the sliding rod 37 is separated from the semi-elliptical groove 35, it can stably enter the semi-elliptical groove 35 from the other end of the semi-elliptical groove 35 again. At the same time, when the pushing column 38 falls through the right angle side of the right-angled trapezoidal block 39, it is in an instantaneous fall. At this time, under the action of the spring force of the stabilizing spring 43, the ball 44 on the slide block 42 can be driven to collide with the side wall of the second chute 41 at a high speed. At this time, the partition plate 3 and the scraper plate 25 can be vibrated to facilitate the shaking off of the materials attached thereto, and also to facilitate the increase of the overall vibration force and thus facilitate the unloading of the screen plate 14.When the scraper plate 25 and the partition plate 3 drive the concrete to spread from the middle of the screen plate 14 to both sides, once the concrete or hard impurities that cannot be discharged after spreading are encountered, they will be pushed to both sides of the U-shaped enclosure 6, and then the material will flow down as a whole, squeezing the T-shaped block 63. When the T-shaped block 63 is squeezed, it will alarm through the alarm part, and then remind the workers to clean the screen plate 14 or slow down the unloading speed of the tank truck, etc., so that timely notification can be made to avoid overflow or accumulation of impurities. At the same time, because the opening of the unloading barrel 11 is square and isosceles trapezoidal, when it is an isosceles trapezoidal, the two sides of the T-shaped block 63 are contractile, which can avoid the situation of being stuck. The setting of the first inclined surface 61 can facilitate the opening of the screen plate 14 at an angle greater than 90 degrees. ;
