Abstract
Description
Technical Field
[0001] The present application relates to the technical field of concrete sampling, and in particular to a concrete coring device. Background Art
[0002] The core drilling method for testing the compressive strength of concrete means that a standard core sample or a small diameter core sample (nominal diameter should not be less than 70mm and not less than 2 times the maximum particle size of aggregate) with a diameter of 100m is drilled in the concrete by core drilling equipment and then subjected to pressure test to determine the strength of structural concrete. This core drilling method is a commonly used method in concrete testing, and a concrete coring machine is often used for coring. It is mainly used for cement concrete in roads, airports, ports, docks, dams, etc. It is an ideal engineering testing equipment for coring compression and flexural tests.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0024] like Figure 1-Figure 2 As shown, the present application provides a concrete coring device, including a mobile base 1, which is placed on the ground. A plurality of sets of casters 2 are installed at the bottom of the mobile base 1, and a plug 21 is provided on one side of the caster 2. The plug 21 is used to limit the movement of the caster 2. Through the cooperation of the caster 2 and the plug 21, the mobile base 1 can be used on various terrains and sites, thereby improving the mobility and flexibility of the equipment. At the same time, a sampling structure 3 is installed on the mobile base 1, and the sampling structure 3 is used for coring operations on cement concrete.
[0025] The sampling structure 3 includes a column 31, which is fixedly mounted on the moving seat 1. A vertical slide 311 is provided on one side of the column 31. A coring machine 5 is installed in the slide 311. The coring machine 5 includes a motor 51. One end of the motor 51 is slidably mounted in the slide 311. A driving unit (not shown in the figure) is connected to the motor 51. The driving unit is used to drive the motor 51 to move up and down along the slide 311. In this embodiment, the driving unit can adopt a screw structure or other methods such as cylinder driving, which will not be described in detail here.
[0026] The output end of the motor 51 extends vertically downward, and a drill bit 52 is fixedly mounted on the output end. The drill bit 52 is a cylindrical drill bit with a cavity inside, and is used to drill holes in concrete for sampling. When sampling is required, the through-hole driving unit drives the motor 51 to move toward the ground, and at this time, the drill bit 52 contacts the ground and performs coring operations on the ground.
[0027] At the same time, in order to prevent dust from splashing when the drill bit 52 is working and causing safety hazards, a protective cover 53 is provided on the outer side of the drill bit 52. One end of the protective cover 53 is fixedly mounted on the bottom surface of the motor 51 and is coaxially arranged with the drill bit 52. The length of the protective cover 53 matches the length of the drill bit 52.
[0028] The protective cover 53 is an elastic and retractable protective cover. When the drill bit 52 contacts the ground, the bottom surface of the protective cover 53 contacts the ground at the same time, isolating the drill bit 52 from the outside. When the drill bit 52 extends into the ground, the protective cover 53 contracts due to the thrust of the motor 51, and the debris generated by the drill bit 52 when working is isolated by the protective cover 53, avoiding potential safety hazards.
[0029] like Figure 3-Figure 4 As shown, a spray device 6 is provided at the bottom of the motor 51, and the spray device 6 includes a water pipe 61 fixedly installed at the bottom of the motor 51, and a plurality of groups of nozzles 62 are provided at the bottom of the water pipe 61. The spraying direction of the nozzles 62 is toward the ground, and a water inlet 611 is provided on the outer side of the water pipe 61. The water inlet 611 is connected to an external water source and is provided with a valve (not shown in the figure). When the drill bit 52 is coring, the valve is opened. At this time, the nozzle 62 continuously sprays water onto the ground, so that the flying dust around the drill bit 52 is reduced, and at the same time, the friction between the drill bit 52 and the concrete can be reduced, and the service life of the drill bit 52 can be extended. In addition, spraying water can also reduce the temperature between the drill bit 52 and the concrete to avoid overheating.
[0030] like Figure 1-Figure 2 As shown, the bottom of the mobile seat 1 is connected to a support rod 4 by bolts, and the other end of the support rod 4 is hinged to a slider 41, and an adjusting bolt 411 is provided on the slider 41, and the adjusting bolt 411 fixes the end of the support rod 4 away from the mobile seat 1 on the column 31;
[0031] A handle 42 is fixedly installed in the middle of the support rod 4. When the device needs to be moved to the workplace, the slider 41 can be removed from the slide groove 311 first, and then the movable base 1 can be pushed to the workplace by holding the handle 42. When arriving at the workplace, the slider 41 can be fixedly installed in the slide groove 311 by adjusting the bolt 411, so that the support rod 4 is stored, thereby reducing the occupied area of the support rod 4.
[0032] In summary, the setting of the protective cover 53 can effectively block the splashing of debris and prevent it from causing harm to surrounding personnel and equipment. At the same time, the continuous spraying of the spray device 6 can reduce the temperature of the drill bit 52 and prevent it from overheating and affecting the operating effect and equipment life.
[0033] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
