Description

Technical Field

[0001] The utility model relates to the technical field of highway maintenance equipment, and more specifically, to a seam grouting device for highway maintenance. Background Art

[0002] Highway maintenance refers to the work carried out to keep the highway in good condition, prevent its quality from deteriorating, and provide good services to highway users. my country attaches more and more importance to preventive maintenance of highways. Considering that the traffic volume of national and provincial trunk roads is large and the diseases and conditions are serious, many national and provincial trunk roads have begun to implement preventive maintenance, and initial results have been achieved.

[0003] Preventive highway maintenance is still in its early stages in the overall development of my country. Due to poor maintenance, some highways have too many and premature quality problems. The highway repair process takes a long time, consumes a lot of manpower and funds, and affects the normal driving of vehicles, forcing them to change routes, etc., thereby increasing the investment in highway funds, further hindering the development of the local economy and making it difficult to improve highway maintenance technology.

[0004] To this end, we should strengthen the importance of preventive highway maintenance and change traditional concepts. Relevant highway departments should strengthen the publicity of the importance of preventive highway maintenance and enhance people's attention. At the same time, we should introduce advanced technologies, improve backward maintenance methods, effectively play the important role of preventive maintenance, let people feel the important role of preventive maintenance on highways, and promote the development of highway maintenance. However, from the actual situation, there are still some problems in the construction of preventive maintenance of national and provincial trunk roads. These problems are mainly manifested in: the preventive maintenance technology used is still at the level of simple grouting, and the latest scientific research results cannot be fully implemented, which is mainly due to the influence and limitations of economic and technical factors. National and provincial trunk roads bear a huge amount of traffic and are prone to diseases and damage. Although the use of primary preventive maintenance measures can eliminate diseases, it is necessary to introduce new preventive maintenance technologies to keep the highway in good use for a longer time, reduce the cost of highway maintenance as much as possible, and reduce the impact of highway maintenance construction on the normal traffic of the road section. The new preventive maintenance technology emphasizes that maintenance work should be carried out when the highway and its structures are in good condition, that is, when the highway has not yet suffered from diseases or has only suffered minor diseases. The comprehensive equipment used in the new preventive maintenance technology includes: an intelligent monitoring system that monitors and analyzes the use of the highway in real time, non-destructive testing equipment for highways that helps maintenance personnel to find problems in time, and preventive maintenance equipment that repairs the highway in time when minor damage occurs. After the sensors in the intelligent monitoring system are deployed, the status data of the highway is collected, and then the data center receives the data from the sensors. The system analyzes the data and finds abnormalities or potential problems. Based on the analysis results of the intelligent monitoring system, it provides support for maintenance decisions and carries out preventive maintenance work according to the recommendations of the intelligent monitoring system. Then the staff can further detect the highway diseases through non-destructive testing equipment. Highway diseases include cracks, potholes, etc. Finally, preventive maintenance equipment is used for construction to fill the cracks and potholes on the road surface.

[0005] The grouting device is required for the grouting and grooving of the road surface. After the road surface cracks are grooved and cleaned, the grouting glue is evenly poured into the groove through the grouting device to complete the grouting work. In the prior art, during the grouting construction, in order to prevent the grouting glue from cooling and solidifying, which affects the construction efficiency, a stirrer is set in the device to heat and stir the grouting glue.

[0006] However, when the existing caulking device is in use, the caulking glue is heated and stirred, and the caulking glue will flow in the device due to its high viscosity.

The diameter of the circular trajectory drawn by the bottom end of the unloading cylinder 21 and the scraper plate 86 when the rotation is greater than the diameter of the stirring blade 63, that is, the stirring blade 63 does not interfere with the scraper plate 86; a grouting mechanism 4 is provided on the fixed cylinder 2, and the grouting mechanism 4 includes a discharge pipe 41, and the discharge pipe 41 is fixedly connected to the fixed cylinder 2, and a flexible pipe 42 is provided on the discharge pipe 41, and a holding pipe 43 is fixedly connected to the flexible pipe 42, and a gate valve is provided on the holding pipe 43, and the grouting glue in the disassembly cylinder 21 is discharged through the holding pipe 43; a monitoring unit is fixedly provided at the bottom of the mobile cart 1, and the monitoring unit can assist the construction personnel in grouting the small gaps in the road surface, determine the positions of the small gaps for the construction personnel, and improve the construction efficiency. The monitoring unit includes a data acquisition module, a data analysis module and a communication module, and the output end of the data acquisition unit is connected to the input end of the data analysis module, and the output end of the data analysis module is connected to the input end of the communication module. The data acquisition module is configured as a monitoring camera and a temperature and humidity sensor. The monitoring camera records the road conditions. The temperature and humidity sensor detects the temperature and humidity of the road surface. The data analysis module is configured as a PLC controller. The data analysis module receives the data acquired by the data acquisition module and performs analysis and processing. The data analysis module transmits the obtained road condition information, temperature and humidity and other information results to the communication module. The output end of the communication module is connected to the input end of the mobile terminal. The communication module is used to transmit the results obtained by the data analysis module. A display screen is fixedly installed on the mobile cart 1. The output end of the communication module is connected to the input end of the display screen. The display screen is used to display the data transmitted by the communication module. Construction personnel can view relevant data through the display screen. A mounting frame 12 is fixedly installed on the mobile cart 1. The holding tube 43 is compatible with the mounting frame 12. The holding tube 43 can be clamped on the mounting frame 12 to achieve positioning of the holding tube 43.

[0034] It should be noted that a power supply module is fixedly provided on the mobile cart 1, and the power supply module is configured as a battery, and the power supply module supplies power to other components. A vibrator 22 is fixedly provided on the disassembly cylinder 21. After the vibrator 22 is started, the vibrator 22 drives the disassembly cylinder 21 and the fixed cylinder 2 to vibrate, which can improve the stirring efficiency of the caulking glue in the disassembly cylinder 21 and the fixed cylinder 2.

[0035] It should also be noted that a pump is fixedly connected to the discharge pipe 41, and the discharge end of the pump is fixedly connected to the flexible tube 42. The start of the pump is used to improve the efficiency of the discharge of the caulking glue, which makes it easy to efficiently inject raw materials into the gap during caulking. The start switch of the pump is set on the holding tube 43.

[0036] The specific implementation scenario is as follows: first, groove the gap on the road surface, cut the loose base material at the edge of the gap, and clean the base material. After the cleaning is completed, the caulking glue is poured into the disassembly cylinder 21, and then the stirring blade 63 is driven to stir the caulking glue. The heating component heats the caulking glue to prevent the caulking glue from lowering its temperature and solidifying. Then, the scraper plate 86 is driven to rotate in the disassembly cylinder 21. The rotation of the scraper plate 86 cleans and scrapes the caulking glue on the inner wall of the disassembly cylinder 21 and the fixed cylinder 2 to prevent the caulking glue from sticking to the disassembly cylinder 21. The inner wall of the fixed tube 2 is difficult to clean. Two staff members are required to cooperate when using this device. One staff member pushes the mobile cart 1 to move, and the other staff member holds the holding tube 43. During the movement of the cart 1, the data acquisition module collects information on the road surface gaps, temperature and humidity. The collected results will be displayed on the display screen. When encountering cracks on the road, open the gate valve and start the pump. The caulking glue in the disassembly tube 21 is efficiently sprayed out through the holding tube 43. After the caulking is completed, the pump and gate valve are closed. As the guideway caulking continues, the caulking glue in the disassembly tube 21 and the fixed tube 2 becomes less and less, and the continuous rotation of the scraper plate 86 can clean the inner walls of the disassembly tube 21 and the fixed tube 2, and improve the discharge efficiency of the caulking glue in the disassembly tube 21 and the fixed tube 2. Avoid caulking glue remaining in the disassembly tube 21 and the fixed tube 2. There are two ways of construction. One way is that the mobile cart 1 moves on the road, and the data acquisition module analyzes the road surface information passed by the mobile cart 1, and then the construction workers fill the gaps. This method is conducive to the construction of small gaps; the other way is that the staff fills the gaps on the road surface by visual means. This method is suitable for filling larger gaps. After the staff completes the filling of the gaps on the road surface and the caulking glue cools in the gaps, the mobile cart 1 is pushed through the filling, and the data acquisition module analyzes the road surface conditions again to ensure that the road surface gaps are completely filled with the caulking glue.

[0037] Refer to the instruction manual Figures 1 to 4After the equipment is used, in order to facilitate the staff to disassemble the disassembly cylinder 21, the disassembly cylinder 21 and the fixed cylinder 2 are cleaned and maintained. Specifically, a positioning mechanism 3 is provided on the support plate 11, and the positioning mechanism 3 includes a sleeve 31, and a thread is provided in the sleeve 31. The sleeve 31 is rotatably set on the support plate 11. A positioning rod 32 is threadedly connected to the sleeve 31, and the positioning rod 32 is set as a threaded rod. A limited seat 33 is fixedly provided on the disassembly cylinder 21, and a groove is provided on the limit seat 33. The positioning rod 32 fits tightly with the limit seat 33.

[0038] It should be noted that when it is necessary to disassemble the disassembly cylinder 21 and clean and maintain the inner wall of the equipment, first hold the positioning rod 32, and then rotate the sleeve 31 horizontally. The sleeve 31 and the positioning rod 32 are threadedly connected. When the sleeve 31 rotates, the positioning rod 32 will move vertically upward. When the positioning rod 32 is not tightly fitted with the limit seat 33, flip the sleeve 31 again to release the positioning between the disassembly cylinder 21 and the fixed cylinder 2, and the disassembly cylinder 21 and the fixed cylinder 2 can be cleaned.

[0039] Refer to the instruction manual Figure 1 and Figure 5 When the staff holds the holding tube 43, in order to facilitate the staff to stand at different angles, the holding tube 43 can efficiently spray the caulking glue. Specifically, a connecting tube 431 is fixedly provided at one end of the holding tube 43 away from the flexible tube 42, and a rolling ball 432 is rollingly provided on the connecting tube 431. The rolling ball 432 is fixedly connected to a bending tube 433, and the bending tube 433 is fixedly connected to a rolling ball 434. The outer rolling sleeve of the rolling ball 434 is provided with a material leveling plate 435.

[0040] It should be noted that when the staff holds the holding tube 43, no matter where they stand or at what angle they hold the holding tube 43, they only need to stick the leveling plate 435 to the ground of the gap. At this time, the caulking glue is sprayed out through the bending tube 433. Under the rolling action of the roller 1 432 and the roller 2 434, the bending tube 433 automatically adjusts the angle relationship with the connecting tube 431, and the leveling plate 435 automatically adjusts the relationship with the bending tube 433. After the caulking glue is sprayed out through the bending tube 433, the leveling plate 435 can spread the caulking glue evenly.

[0041] Refer to the instruction manual Figure 1 and Figure 2 In order to remove dust in the gaps when grouting the road surface and improve the adhesion between the logistics and the gaps, specifically, a blower 5 is fixedly installed in the mobile cart 1, and the exhaust end of the blower 5 is fixedly connected to an exhaust hood 51, and the exhaust port of the exhaust hood 51 is arranged toward the ground.

[0042] It should be noted that after the blower 5 is started, the mobile cart 1 is driven to move, and the wind generated by the blower 5 is blown toward the gap on the ground through the exhaust hood 51, the dust in the gap will be blown away, and then the gap will be filled.

[0043] Refer to the instruction manual Figures 1 to 3 and Figure 6 In order to improve the mixing efficiency of the caulking glue in the disassembly cylinder 21 and the fixed cylinder 2, specifically, the stirring mechanism 6 also includes a rotation driver 61, the rotation driver 61 is fixedly arranged in the mobile cart 1, and a gear box 62 is also fixedly arranged in the mobile cart 1. The output shaft of the rotation driver 61 is fixedly arranged with the input end of the gear box 62, and the output end of the gear box 62 extends into the fixed cylinder 2 and is rotatably arranged with the fixed cylinder 2. The stirring blade 63 is fixedly sleeved on the output end of the gear box 62. The input end of the gear box 62 refers to the port for transmitting power from the outside to the inside, and the output end of the gear box 62 refers to the port for transmitting power from the inside to the outside.

[0044] It should be noted that the rotary driver 61 is configured as a motor, and the output shaft of the motor is fixedly configured with the input end of the gear box 62. The blades on the stirring blade 63 are inclined, and the inclined blades can improve the stirring effect of the caulking glue.

[0045] It should also be noted that the rotary driver 61 is started. The output shaft of the rotary driver 61 drives the output shaft of the gear box 62 to rotate, and the rotation of the output end of the gear box 62 drives the stirring blade 63 to rotate, so as to achieve the effect of efficiently stirring the caulking glue in the disassembly cylinder 21 and the fixed cylinder 2.

[0046] Refer to the instruction manual Figures 1 to 3 After all the gaps on the road surface are filled, sometimes some caulking glue will remain in the disassembly cylinder 21 and the fixed cylinder 2. In order to reuse the remaining caulking glue, it is necessary to efficiently discharge the remaining caulking glue in the disassembly cylinder 21 and the fixed cylinder 2. Specifically, a material guiding mechanism 7 is also provided on the mobile cart 1. The material guiding mechanism 7 includes a discharge pipe 2 71 and a discharge pipe 3 72. The discharge pipe 2 71 and the discharge pipe 3 72 are both fixedly connected to the fixed cylinder 2. The end of the discharge pipe 3 72 away from the fixed cylinder 2 is fixedly connected to the discharge pipe 2 71, and the discharge pipe 2 71 is fixedly connected with an auxiliary pipe 73.

[0047] It should be noted that gate valves are fixedly provided on the discharge pipe 2 71 and the discharge pipe 3 72 , and the output end of the auxiliary pipe 73 is fixedly connected to a pump, which can improve the circulation efficiency of the caulking glue in the auxiliary pipe 73 .

[0048] It should also be noted that when the grouting is completed, and there is still some grouting glue in the disassembly cylinder 21 and the fixed cylinder 2, the gate valve and the pump connected to the discharge pipe 41 are closed, and the gate valve and the pump on the disassembly cylinder 21 and the fixed cylinder 2 are opened. The grouting glue is efficiently discharged through the auxiliary pipe 73, which is convenient for the next use of the grouting glue.

[0049] Refer to the instruction manual Figures 1 to 3 , Figure 6 and Figure 7 , after the cylinder 21 is disassembled, in order to facilitate the cleaning of the scraper plate 86, and the scraper plate 86 reduces the use of the driver when in use, thereby reducing the use cost, specifically, the scraper mechanism 8 also includes a cover plate 81, which is arranged on the disassembly cylinder 21, and the cover plate 81 is installed on the disassembly cylinder 21 by bolts. A baffle plate 82 is rotatably arranged on the cover plate 81, and the baffle plate 82 can not only prevent the irritating smell generated by the caulking glue in the disassembly cylinder 21 and the fixed cylinder 2 from diffusing outward, but also effectively prevent the rapid decrease in the temperature of the caulking glue in the disassembly cylinder 21 and the fixed cylinder 2, thereby achieving the effect of heat preservation. A fixed seat 83 is fixedly arranged at the bottom of the cover plate 81, and an annular slide groove is provided in the fixed seat 83. A sliding rod 84 is slidably arranged in the annular slide groove of the fixed seat 83, and a clamping rod 85 is fixedly arranged on the sliding rod 84. The scraper plate 86 is fixedly arranged on the clamping rod 85, and a clamping groove 631 is provided on the stirring blade 63, and the clamping rod 85 is clamped with the clamping groove 631.

[0050] It should be noted that the rotation of the stirring blade 63 drives the clamping rod 85 to rotate, and the rotation of the clamping rod 85 drives the scraper plate 86 to scrape off the caulking glue remaining on the inner walls of the disassembly cylinder 21 and the fixed cylinder 2. When the cylinder 21 needs to be disassembled, after removing the bolts, pull the cover plate 81 upwards so that the clamping rod 85 is not clamped in the slot 631.

[0051] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
