Road surface core drilling machine mud guard device manufacturing method

Abstract

The invention belongs to the technical field of highway testing equipment, and relates to a road surface core drilling machine mud guard device manufacturing method. A steel plate is used for manufacturing a cylindrical mud guard barrel of a hollow structure first, wherein the specific size of the mud guard barrel is determined according to core drilling machine drill bits with different models, and a drill bit hole is formed in the center of the upper end of the mud guard barrel; then, a steel plate is used for manufacturing a base plate of a square structure, wherein a circular hole is formed in the center of the base plate in an excavated mode; next, the circular hole of the base plate and the lower end of the mud guard barrel are in fixed seal welding, and it is ensured that the central axis of the mud guard barrel and the central axis of the circular hole are located in the same vertical axis at the same time; or, a check block or a baffle ring is fixedly welded to the lower end edge of the mud guard barrel; since the diameter of the circular hole in the center of the base plate is larger than the diameter of the mud guard barrel, the circular hole of the base plate is connected to the lower end of the mud guard barrel in a sleeved mode. The road surface core drilling machine mud guard device manufacturing method is practical, a manufactured road surface core drilling machine mud guard device is reasonable in design, simple in structure, easy and convenient to manufacture, low in cost, good in mud guard effect and environmentally friendly, and the materials are easy to get.

Description

Technical field: [0001] The invention belongs to the technical field of road detection equipment manufacturing, and relates to a method for preparing a mudguard of a road surface coring machine. The prepared mudguard can ensure the safe operation of the road surface coring machine, and at the same time avoid the generation of mud in the process of coring and rotary cutting pollute. Background technique: [0002] With the increasing investment in highway construction in China, the total mileage of highways in China has reached 4,237,500 kilometers by the end of 2012, and the "five vertical and seven horizontal" national highways have been fully completed. With the rapid development of the country, the quality requirements for road construction are also increasing day by day, which requires a complete and mature road inspection technology; the traditional inspection method is to use a road surface coring machine to conduct cement stabilized base, cement concrete surface and as...

[0002] With the increasing investment in highway construction in China, the total mileage of highways in China has reached 4,237,500 kilometers by the end of 2012, and the "five vertical and seven horizontal" national highways have been fully completed. With the rapid development of the country, the quality requirements for road construction are also increasing day by day, which requires a complete and mature road inspection technology; the traditional inspection method is to use a road surface coring machine to conduct cement stabilized base, cement concrete surface and asphalt concrete surface. Drilling and coring, and then analyzing the data of the obtained samples to check whether the road construction is qualified; as we all know, in order to ensure that the motor does not exceed 70 °C when the road surface coring machine is operating, water needs to be added continuously during the entire drilling process. In order to cool the drill bit, while the core drill bit rotates at high speed under the drive of the motor to cut the cement stable base and the concrete surface layer, a large amount of gravel and dust will be generated. At the same time, the cooling water on the core drill bit flows to the ground and the core drill The gravel and dust produced in the process are mixed to produce mud, which will be splashed by the centrifugal force generated by the high-speed rotation of the coring bit, which brings safety hazards to the operators of the road core machine, and the splash of mud will pollute the surrounding environment and Operator's clothing; there is no relevant equipment and method in the prior art to overcome this problem, so seek to design a preparation method for the mudguard of the road surface coring machine, and the prepared mudguard can ensure that the road surface coring machine The personal safety of the operator and the prevention of mud pollution to the environment have good economic prospects and practical value
