[0029] Embodiment 1

[0030] Refer to Figures 1 to 6, which is the first embodiment of the present utility model, provides a concrete core drill. This core drill includes a core drilling assembly 100 and a braking assembly 200. Among them, the core drilling assembly 100 includes a trolley 101, a positioning rod 102 arranged on the trolley 101, a positioning slider 103 arranged on the positioning rod 102, a driving motor 104 arranged on the positioning slider 103, and a drill bit 105; the braking assembly 200 is arranged at the bottom of the trolley 101 and includes a pulley 201, a positioning column 202, a fixed seat 203 connected to the positioning column 202, a hook spring 204 arranged in the positioning column 202, a crank 205 connected to the positioning column 202, and a lever 206 connected to the fixed seat 203.

[0031] Among them, a reinforcing rod 101a is further arranged on the trolley 101. One end of the reinforcing rod 101a is rotatably connected to the trolley 101, and the other end is rotatably connected to the positioning rod 102. The positioning slider 103 is slidably connected to the positioning rod 102, and the positioning slider 103 can move up and down in the vertical direction of the positioning rod 102. The driving motor 104 is fixed to the positioning slider 103, and the output shaft of the driving motor 104 is fixedly connected to the drill bit 105. The direction of the drill bit 105 is vertically downward. Four pulleys 201 are arranged, and the pulleys 201 are distributed in a rectangle at the bottom of the trolley 101. The positioning column 202 is arranged in the center of the two pulleys 201 at the front end of the trolley 101, and a cross bar 202a is horizontally arranged in the positioning column 202. The fixed seat 203 is slidably connected to the positioning column 202, and a second cross bar 203a is horizontally arranged in the fixed seat 203. One end of the hook spring 204 is connected to the cross bar 202a, and the other end is connected to the second cross bar 203a. The crank 205 is rotatably connected to the side wall of the positioning column 202, and a reset rod 204a is further arranged on the crank 205. The lever 206 is rotatably connected to the side wall of the fixed seat 203, a pedal 205a is arranged on the lever 206, and the lever 206 is also rotatably connected to the crank 205.

[0032] During use, the cart 101 is moved to the working area via the pulley 201, and the reinforcing rod 101a can reinforce the positioning rod 102. In order to brake and fix the cart 101, in the initial state, the hook spring 204 pulls the second crossbar 203a to shrink the fixing seat 203 in the positioning column 202. At this time, the fixing seat 203 is not in contact with the ground, and the pulley 201 can slide on the ground normally. The staff can rotate the lever 206 around the rotation point on the side wall of the fixing seat 203 by stepping on the pedal 205a. Since the lever 206 is also in contact with the fixing seat 203, the fixing seat 203 is not in contact with the ground. The crank 205 is rotatably connected, so during the rotation of the lever 206, the crank 205 also rotates around the rotation point on the side wall of the positioning column 202. During the rotation of the lever 206 and the crank 205, the distance between the two is stretched, so that the fixing seat 203 and the positioning column 202 overcome the pulling force of the hook spring 204 and extend. When the lever 206 and the crank 205 are rotated until the connecting rod of the two is vertical, the length of the positioning column 202 and the fixing seat 203 is the longest, and the pedal 205a is continued to be stepped on to make the lever 206 continue to rotate. At this time, the lever 20 6 and the crank 205 connecting rod is no longer vertical, because the reset rod 204a is provided with a limit rod 204b, the limit rod 204b is close to the side wall of the positioning column 202 when the crank 205 rotates, and when the limit rod 204b is against the side wall, the lever 206 cannot continue to rotate, and the pedal 205a is released. At this time, the length of the fixed seat 203 extends beyond the height of the pulley 201, and one end of the cart 101 is lifted up. The gravity of the cart 101 presses down because the limit rod 204b is against the side wall of the positioning column 202, and the lever 206 cannot rotate, and the device is locked. The trolley 101 is locked and the driving motor 104 is started to rotate the drill bit 105, and drilling is performed by moving the positioning slider 103 on the positioning rod 102. This is the normal operation of the coring machine and will not be described in detail here. After the operation is completed, the crank 205 rotates with the lever 206, and the reset rod 204a on the crank 205 is tilted. By stepping on the reset rod 204a, the lever 206 can be reset and retracted, and the fixed seat 203 is pulled up by the hook spring 204 and reset, and the pulley 201 falls to the ground again, and the trolley 101 can be pushed.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
