DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: a tunnel floor drilling device, including a box body 1, a moving wheel 2, a movable plate 3, a fixed plate 4, a receiving sleeve 5, an adjusting rod 6, a first motor 7, a moving block 8, a limiting plate 9, a second motor 10, a drill bit 11, a height sensor 12, a limiting plate 13, a controller 14, a display 15, a shielding plate 16, a transfer frame 17, a connecting pipe 18, a pump 19, a filter screen 20 and a counterweight plate 21. When the tunnel floor drilling device is used, Figure 1 , Figure 2 and Figure 3 First, the box body 1 and the movable plate 3 engaged in the fixed plate 4 fixedly connected to the front side thereof can be pulled upward, and then the movable plate 3 can be pulled, so that the device can be moved on the tunnel floor to be drilled under the action of the movable wheel 2 fixedly installed by the screws on the outer lower side of the box body 1, and the drill bit 11 connected through the coupling under the second motor 10 is located above the tunnel floor drilling hole, and then the controller 14 embedded and installed on the inner side of the left front upper end of the box body 1 can be used to control the first motor 7 connected through the coupling on the right side of the adjusting rod 6 and the second motor 10 nested in the receiving sleeve 5 to operate, so that the first motor 7 drives the adjusting rod 6 connected to the coupling on the left side thereof to rotate under the engaging limit of the box body 1, so that the second motor 10 drives the drill bit 11 connected to the coupling below it to rotate;

[0027] Since the outer sides of the left and right ends of the adjusting rod 6 are threadedly connected with moving blocks 8 that are symmetrically fitted with the box body 1, the inner side of the lower end of the moving block 8 is rotatably connected with a limiting plate 9, and the inner lower side of the limiting plate 9 is provided with a receiving sleeve 5 that rotates therewith, therefore, through the operation of the first motor 7, it is convenient for the adjusting rod 6 to drive the moving block 8 to move under the fitting limit of the box body 1, so that the moving block 8 drives the receiving sleeve 5 to move downward through the limiting plate 9, so as to facilitate the drilling of the lower tunnel floor by the rotating drill bit 11. During the drilling process, the height sensor 12 embedded on the inner side of the middle part of the upper end of the receiving sleeve 5 and the display 15 embedded on the inner side of the left front upper end of the box body 1 can be controlled by the controller 14 to cooperate with each other to make the height sensor 12 perform height sensing, so that the display 15 limits the data sensed by the height sensor 12, thereby facilitating the sensing of the drilling depth, and achieving the purpose of accurate drilling;

[0028] like Figure 1 , Figure 3and Figure 4 , and the pump 19 installed after the transfer frame 17 can be controlled by the controller 14 to operate. Since the inner side of the left front end and the inner side of the right front end of the transfer frame 17 are both threadedly connected with the connecting pipe 18, the lower end of the connecting pipe 18 is obliquely threadedly connected to the inner sides of the left and right ends of the box body 1, and the inner side of the transfer frame 17 is nested and fitted with a filter screen 20, and the filter screen 20 is fixedly connected with a counterweight plate 21 that is fitted with the transfer frame 17. Therefore, through the operation of the pump 19, the heat and waste generated by the drill bit 11 drilling a hole are sucked into the transfer frame 17 through the connecting pipe 18, and the waste is filtered and collected through the filter screen 20, and then discharged through the pump 19 for heat dissipation;

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 After the drilling is completed, the first motor 7 can be controlled by the controller 14 to operate, so that the drill bit 11 rises and is stored in the box body 1. After the device is used for a long time, the counterweight plate 21 can be moved up to take the filter screen 20 out of the transfer frame 17, and the waste debris on the filter screen 20 can be cleaned. The screws fixing the pump 19 and the box body 1 can be disconnected, and the pump 19 can be disassembled, repaired and replaced. The baffle plate 16 can be rotated to disconnect its shielding of the limiting plate 13, and then the screw fixing of the receiving sleeve 5 and the limiting plate 13 set in front of it can be disconnected, so as to disassemble, repair and replace the second motor 10 nested in the receiving sleeve 5.
