Description

TECHNICAL FIELD

[0001] The utility model relates to the expressway maintenance blowing field, concretely relates to an expressway maintenance equipment for blowing and maintaining the expressway pavement. BACKGROUND

[0002] In the long-term use process of the expressway, the pavement will accumulate various dusts, sundries and fine particles and other pollutants generated by vehicle driving. These pollutants not only affect the aesthetic degree of the pavement, but more importantly, will reduce the friction of the pavement, increase the safety hidden danger of vehicle driving, and are also not conducive to the accurate detection and evaluation of the pavement condition. When it snows, the pavement will also have accumulated snow, which also needs to be blown and cleaned. The traditional expressway pavement maintenance cleaning method is relatively single, and a cleaning device with a fixed angle and position is mostly used, which is difficult to accurately and efficiently clean the pollutants at different road conditions and different positions. For example, some simple blowing equipment has a fixed air outlet angle, which cannot be flexibly adjusted according to the actual situation of the pavement, such as the change of the pavement slope and the difference of the pollutant accumulation position. This results in that the cleaning effect is greatly reduced in some special sections or complex road conditions, and more manpower, material resources and time cost are needed to repeatedly clean or supplement the cleaning operation. Moreover, the existing maintenance equipment also has defects in the connection structure. The lower end outlet part of the blowing air pipe can be adjusted, which will affect the normal use of the equipment and the continuity and efficiency of the maintenance work. The shape design of the blowing air outlet is also lack of targeted consideration, which cannot well meet the optimization demand of the blowing effect under different wind forces. In summary, in order to overcome the defects of the existing expressway maintenance equipment in the blowing angle adjustment, the stability of the connection structure and the optimization of the blowing effect, it is particularly necessary to develop a new type of expressway maintenance equipment which has a blowing air outlet angle that can be flexibly adjusted, a stable connection structure and can effectively improve the blowing effect.

[0017] In the present application, blowoff outlet 4 is in the shape of a circular truncated cone as a whole.

[0018] In the present application, telescopic action unit 6 is adjustable air cylinder or oil cylinder.

[0019] In the present application, the upper end of connecting joint 3 is placed outside the lower end of blowoff pipe 2 and wraps the lower end of blowoff pipe 2, and the two are further fixed by bolt 10.

[0020] The implementation process of the highway maintenance equipment described in the present application will be described in detail as follows:

[0021] I. Equipment assembly: Prepare the maintenance vehicle body 1, ensure its structural integrity and stability, and reasonable space layout. Select the appropriate vertical installation position at the rear end of the maintenance vehicle body 1, and install the blowing air pipe 2. The upper end of the blowing air pipe 2 is accurately connected with the high-pressure fan previously installed on the maintenance vehicle body 1, and is firmly connected to ensure that the airflow generated by the high-pressure fan can smoothly enter the blowing air pipe 2. Take the corrugated connecting joint 3 made of plastic material, put its upper end on the lower end of the blowing air pipe 2, so that the connecting joint 3 wraps the lower end of the blowing air pipe 2, and use the bolt 10 to fasten it according to the specified torque, to ensure that the connection is tight and there is no risk of leakage. At this time, the sealing and firmness of the connection part should be carefully checked to prevent loosening or air leakage during subsequent use. Fix the telescopic action unit 6 (such as a pneumatic cylinder or an oil cylinder) on the designated mounting base at the rear end of the maintenance vehicle body 1, ensure that its installation position is accurate and fixed firmly, and make its action end flexible to stretch and contract without interference from other components. Install the rotating connecting block 7 through the rotating shaft 9 at the corresponding position at the rear end of the maintenance vehicle body 1, and the rotating shaft 9 needs to be firmly fixed on the maintenance vehicle body 1 to ensure that the rotating connecting block 7 can rotate freely and smoothly around the rotating shaft 9, and the friction during rotation is within a reasonable range, which will not affect the adjustment accuracy and action response speed. The upper end of the connecting rod 8 is reliably connected with one end of the rotating connecting block 7, for example, by welding, high-strength bolt connection or other appropriate connection methods, to ensure that the connection strength is sufficient to withstand various forces generated during equipment operation due to blowing force and equipment vibration. Then connect the lower end of the connecting rod 8 with the blowing air outlet 4, and the connection method should also ensure stability and not negatively affect the blowing effect of the blowing air outlet 4.

[0022] II. Equipment commissioning phase: After completing the assembly of the equipment, first of all, the high-pressure fan is individually commissioned. Start the high-pressure fan, check whether its operation is smooth, whether there is abnormal noise or vibration, and at the same time use professional wind speed measuring instruments to detect whether the wind speed at the inlet of the blowing wind pipe 2 reaches the design requirement. If not, the speed, blade angle and other parameters of the high-pressure fan need to be adjusted or the electrical control system of the fan needs to be checked whether it is working normally. Adjust the adjusting mechanism 5. Control the telescopic action unit 6 to perform telescopic action, observe whether the rotating connecting block 7 can rotate smoothly along the rotating shaft 9, and whether the blowing air outlet 4 driven by the connecting rod 8 can rotate flexibly and accurately. Check whether the angle range during rotation meets the design expectation. If the angle range is not accurate, the installation position of the rotating connecting block 7, the length of the rotating shaft 9 or the stroke of the telescopic action unit 6 need to be adjusted. At the same time, observe whether the blowing air outlet 4 is stable in different angles, whether there is deflection or turbulence phenomenon, if there is a problem, check whether the connection between the connecting rod 8 and the blowing air outlet 4 and the rotating connecting block 7 is loose or deformed. Check the sealing condition of the connection part between the connecting joint 3 and the blowing wind pipe 2 during the operation of the equipment. Smoke generator and other tools can be used to detect the sealing performance of the connection part when the high-pressure fan is running. If smoke leakage is found, the bolts 10 need to be further tightened or the sealing surface of the connecting joint 3 and the blowing wind pipe 2 needs to be checked whether it is smooth, and the sealing parts such as gaskets can be replaced if necessary.

[0023] III. Equipment operation: After the equipment commissioning is completed and all performance indicators meet the requirements, the maintenance equipment is driven to the highway section that needs to be maintained. According to the actual situation of the road surface, such as the slope of the road surface, the distribution and accumulation of pollutants, etc., the operator adjusts the blowing air outlet angle of the blowing air outlet 4 by controlling the telescopic amount of the telescopic action unit 6. For example, when there is an uphill section on the road surface and the pollutants are concentrated near the road shoulder, the telescopic amount of the telescopic action unit 6 can be appropriately increased to make the blowing air outlet 4 rotate to the uphill direction and to the side of the road shoulder, so as to ensure that the high-pressure airflow can effectively blow away the pollutants. During the operation of the equipment, the operating state of the high-pressure fan is continuously monitored, including the wind speed, wind pressure, motor temperature and other parameters, to ensure that it is always within the normal working range. At the same time, the blowing effect of the blowing air outlet 4 is observed. If the cleaning effect is not good, such as there are still a large number of pollutants remaining or local cleaning is not thorough, the blowing air outlet angle can be adjusted or the working performance of the high-pressure fan can be checked, such as whether the fan filter is blocked, and appropriate treatment can be carried out. Regularly maintain the equipment, including checking the seals of the telescopic action unit 6, the amount of lubricating oil, the wear condition of the rotating connecting block 7 and the rotating shaft 9, the connection tightness of the connecting joint 3 and the blowing wind pipe 2, etc. Repair or replace damaged parts in time to ensure the long-term stable operation of the equipment and good maintenance effect.

[0024] IV. Equipment shutdown phase: when the maintenance work of a highway pavement is completed or the equipment needs to be shut down for other reasons, first stop the operation of the high-pressure air blower, and gradually stop the airflow in the blowing air pipe 2.

[0025] The telescopic action unit 6 is restored to the initial position, and the blowing air outlet 4 returns to the designed initial angle position, avoiding unnecessary stress or deformation of the adjusting mechanism 5 due to long-term non-initial position. The equipment is comprehensively checked, and various data and problems found during the operation of the equipment are recorded, providing a basis for subsequent equipment maintenance, improvement and optimization. The maintenance equipment leaves the working area and is parked in the designated equipment storage place, and is properly stored according to the equipment storage requirements, such as covering the dust cover, preventing the equipment from being damp and rusty, etc.

[0026] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
