Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment for construction, and in particular to a comprehensive prestressed pipeline grouting device. Background Art

[0002] Prestressed concrete structures are widely used in my country's infrastructure construction due to their good crack resistance, high rigidity, material saving and light weight.

[0003] Although the current grouting device is equipped with an agitator and a pressurized conveying function, which can mix and stir the added grouting material and water, there are still other problems during use, such as the inability to quantitatively add raw materials and water. The slurry is mixed with slurry and water in a specific proportion. This step is generally observed manually based on experience. If the ratio of the two deviates too much, it will have a great impact on the quality of the slurry, and the cleaning water cannot be recycled and reused. Before the steel strand is inserted, the inner wall of the pipeline needs to be moistened with medium water. While checking the air tightness of the pipeline, the residual impurities in the pipe are cleaned. The cleaning water is directly discharged to the ground from the other end of the pipeline after use. Not only does it require personnel to collect and process the impurities after discharge, it will also cause a waste of water resources. At the same time, the grouting effect of the slurry is poor. After mixing, the slurry is directly delivered to the pipeline by a pressurized pipeline. During the transportation process, the prestressed tendons are bonded. Due to the durability problems of the grouting process, the grouting of the prestressed pipeline often has the phenomenon of insufficient grouting or loose grouting, and its practicality is low.

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0023] The present invention provides a comprehensive prestressed pipeline grouting device, comprising a shell 100, a fixing plate 110 and a water tank 200 installed in the shell 100, a feed hopper 120 is welded through the top of the shell 100; a stirring tank 300 is arranged through the top of the fixing plate 110, the feed hopper 120 is connected with the stirring tank 300, weighing mechanisms 400 are installed on both sides of the stirring tank 300, and a stirring mechanism 310 is arranged inside the stirring tank 300; a water supply mechanism 210 is arranged on one side of the water tank 200, and the water supply mechanism 210 is connected to the water tank 200. 0 and a stirring tank 300; a recovery mechanism 500 is arranged on the top of the shell 100, two pressurizing components 600 are bolted inside the shell 100, one side of the water tank 200 is connected with the pressurizing component 600 through the first connecting pipe 214, and the bottom of the stirring tank 300 is connected with the pressurizing component 600 through the second connecting pipe 320; a volume measuring component 700 and a vibrator 800 are bolted inside the shell 100 respectively, an output end of the vibrator 800 is fixedly sleeved with a cable 810, and a vibrating terminal 820 is installed at the other end of the cable 810.

[0024] By first feeding the slurry from the feed hopper 120, the slurry fed into the feed hopper 120 will fall downward into the mixing tank 300. The slurry falling into the mixing tank 300 will increase the weight of the mixing tank 300. As the weight increases, it will be fed back to the outside through the weighing mechanism 400. When the slurry falling into the mixing tank 300 reaches a predetermined value, the feeding is stopped, and then the water supply mechanism 210 is started to transport the water in the water tank 200 to the mixing tank 300. It can have a quantitative proportioning function, and the specific gravity of the slurry and water fed in is monitored in real time, thereby improving the feeding efficiency of the slurry and water and ensuring the mixing quality of the final slurry.

[0025] Exemplarily, the weighing mechanism 400 includes a weighing sensor, a fixing block 330 is symmetrically welded on the surface of the mixing tank 300 , and the weighing sensor is installed between the bottom of the fixing block 330 and the fixing plate 110 .

[0026] In one embodiment, the stirring mechanism 310 includes a stirring shaft 311 , the surface of which is rotatably connected to the inside of the stirring tank 300 via a bearing, a stirring motor 312 is fixedly sleeved on the bottom end of the stirring shaft 311 , and a stirring blade 313 is installed on the surface of the stirring shaft 311 .

[0027] After the stirring motor 312 is started, the stirring shaft 311 starts to rotate, driving the stirring blades 313 to rotate, thereby completing the stirring work in the stirring tank 300 .

[0028] In one embodiment, the water supply mechanism 210 includes a water pump 211, which is bolted to one side of the water tank 200. The two ends of the water pump 211 are respectively fixedly sleeved with a suction pipe 212 and a discharge pipe 213. The other end of the suction pipe 212 is connected to one side of the water tank 200, and the other end of the discharge pipe 213 extends to the interior of the mixing tank 300.

[0029] After the water pump 211 is started, the water in the water tank 200 is sucked in, and after being sucked in, the water is transported to the mixing tank 300 through the drain pipe 213 .

[0030] In one embodiment, the recovery mechanism 500 includes a water tank 510, which is bolted to the top of the shell 100. The bottom of the water tank 510 is connected to the water tank 200 through a third connecting pipe 520. A metal filter screen 530 is bolted to the inside of the water tank 510. A fourth connecting pipe 540 is passed through one side of the water tank 510, and a water inlet cover 550 is fixedly sleeved on the other end of the fourth connecting pipe 540.

[0031] By extending the discharge pipe of the pressurizing component 600 into the prestressed pipe and fixing the water inlet cover 550 to the other end of the pipe with a clamp, then opening the valve on the first connecting pipe 214 and starting the pressurizing component 600 connected thereto, the pressurizing component 600 will send the water entering the interior into the pipe after starting, and the water flowing in the pipe will enter the water tank 510 from the other end along with the impurities. The metal filter 530 in the water tank 510 will intercept the impurities, and the water will flow back to the water tank 200 from the third connecting pipe 520 through the holes, so that the cleaning water can be recycled and reused, the operation is simple and convenient, the waste of water resources is reduced, and it is beneficial for personnel to collect and treat impurities.

[0032] After the interior of the prestressed pipe is cleaned, the stranded wire is inserted into it. After the stranded wire is inserted, the micro-robot part of the volume measurement component 700 is sent into the pipe to scan the situation inside the pipe. The image after the scan will measure the volume inside the pipe and display it on the display. Then the valve on the second connecting pipe 320 is opened to allow the slurry in the mixing tank 300 to enter another pressurizing component 600 connected to it. The slurry flows inside the pressurizing component 600 and generates lift through the rotation of the impeller in the pump, so that the internal slurry obtains energy and is discharged. When the slurry is poured in, the personnel on the side adjust the amount of the grouting liquid according to the volume error between the grouting liquid and the volume measurement. Finally, the vibrating end 820 is extended into the grouting liquid and the vibrator 800 is started to vibrate it. This can improve the grouting injection effect of the device, ensure the fullness of the slurry in the prestressed pipe, and has high practicality.

[0033] In one embodiment, ventilation slots 130 are formed on both sides of the housing 100 , and dustproof nets 131 are bolted to the ventilation slots 130 .

[0034] The ventilation slots 130 are provided to dissipate heat within the housing 100 , and dustproof nets 131 are bolted to the ventilation slots 130 to prevent dust and other debris from entering the housing 100 through the ventilation slots 130 . In one embodiment, a universal wheel 140 is installed at the bottom of the housing 100 , and a brake pad is installed on the surface of the universal wheel 140 .

[0035] The installation of the universal wheel 140 allows the comprehensive prestressed pipe grouting device to be moved at will. A brake pad is installed on the surface of the universal wheel 140 to fix the universal wheel 140, so that the comprehensive prestressed pipe grouting device will not move when in use.

[0036] In one embodiment, a PLC controller 900 is bolted to one side of the housing 100 .

[0037] The data measured by the weighing sensor is fed back to the PLC controller 900, and the PLC controller 900 is used to control the start and stop of the comprehensive prestressed pipe grouting device.

[0038] In one embodiment, shock-absorbing pads are installed between the pressurizing assembly 600 and the vibrator 800 and the housing 100 .

[0039] The present invention adopts the use of a fixed plate 110, a fixed block 330, a stirring tank 300 and a weighing sensor, and can have a quantitative proportioning function, and can monitor the specific gravity of the slurry and water put in in real time, thereby improving the efficiency of putting the slurry and water and ensuring the mixing quality of the final slurry; the present invention can recycle and reuse the cleaning water through the combined use of a water tank 510, a water inlet cover 550, a first connecting pipe 214 and a second connecting pipe 320, and the operation is simple and convenient, which reduces the waste of water resources and is conducive to the collection and treatment of impurities by personnel; the present invention effectively improves the grouting injection effect of the device by installing both the volume measuring component 700 and the vibrator 800 inside, and extending the vibrating end 820 to the outside through the cable 810, thereby ensuring the fullness of the slurry in the prestressed pipe and having high practicality.
