Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete drilling device. Background Art

[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete.

[0003] However, the existing concrete drilling devices still have the following shortcomings: 1. During the drilling process, the friction between the drill bit and the concrete will generate a lot of heat and dust, which will affect the health of the operator and the working environment; 2. The concrete drilling devices in the prior art may be bulky and inconvenient to move between different work locations, and they do not have a limit function, which may cause the device to be unstable and prone to accidents such as tilting and rolling, posing a safety hazard to the operator and the surrounding environment. Therefore, we propose a concrete drilling device. Utility Model Content

A movable hole 13 is passed through from top to bottom, the front end of the movable block 12 is fixedly connected with a connecting block 14, the upper end of the connecting block 14 is fixedly connected with a second rotating motor 15, the middle part of the upper end of the bottom plate 1 is fixedly connected with a water tank 16, the upper front part of the water tank 16 is provided with a water inlet 17, the lower left end of the water tank 16 is inserted and fixedly connected with a suction pipe 18, the end of the suction pipe 18 away from the water tank 16 is fixedly connected with a pump 19, the lower end of the pump 19 is fixedly installed with an output pipe 20, the end of the output pipe 20 away from the pump 19 is inserted and fixedly connected with a connecting pipe 21, the left and right parts of the outer surface of the connecting pipe 21 are both inserted and fixedly connected with two guide pipes 22, the outer surfaces of the four guide pipes 22 are provided with a number of nozzles 23, and the output end of the second rotating motor 15 passes through the connecting block 14 and is fixedly connected with a drill bit 24.

[0025] In this embodiment, the diameter of the two movable holes 13 is consistent with the diameter of the four fixed columns 3. The two fixed columns 3 on the front side are arranged in the two movable holes 13. The diameter of the movable hole 13 is consistent with the diameter of the fixed column 3, so that the movable block 12 can move along the direction of the fixed column 3 when moving up and down, which plays a guiding role and ensures that the movement trajectory of the drill bit 24 is accurate; the lower end of the screw rod 11 is movably connected to the upper end of the base plate 1 through a bearing. Through the bearing connection, the friction resistance between the screw rod 11 and the base plate 1 is reduced during rotation, so that the rotation of the screw rod 11 is smoother and the energy loss is reduced; the two bolts 7, handles 8 and conical teeth 9 are distributed in left and right mirror images.

When drilling, the device is not easy to tilt or shake; the lower end of the pump 19 is fixedly connected to the upper end of the base plate 1, and the pump 19 is fixed on the base plate 1, which can increase the stability of the entire device.

Several nozzles 23 are distributed at equal distances and do not contact each other.

[0026] It should be noted that the utility model is a concrete drilling device. During specific use, the device is first moved to the position where drilling is required by the push handle 4, the handle 8 is rotated to move the bolt 7 downward, the conical ground tooth 9 is inserted into the ground, the friction between the device and the ground is increased, and the device is fixed. Then the first rotary motor 10 is started to drive the screw 11 to rotate, so that the movable block 12 moves up and down on the screw 11, thereby adjusting the height of the drill bit 24. When the appropriate position is reached, the second rotary motor 15 is started to drive the drill bit 24 to rotate and drill the concrete. During the drilling process, the pump 19 is started to suck the water in the water tank 16 into the pump 19 through the suction pipe 18, and then transported to the connecting pipe 21 through the output pipe 20, and finally sprayed out through the guide pipe 22 and the nozzle 23 to cool the drill bit 24 and settle the dust generated by drilling. Through the above working principle, the device realizes the drilling operation of concrete, and improves the work efficiency and the comfort of the operator through the cooling and dust reduction system.
