[0002] Hydraulic anchor drilling rigs are industrial equipment primarily used in support engineering for coal mine roadways and tunnels. Powered by a hydraulic system, they perform drilling operations to install anchor bolts and reinforce the roadway. They offer advantages such as explosion-proof safety, reasonable structure, convenient operation, high power, high efficiency, long service life, and labor-saving features. They also boast an extremely low failure rate, are lightweight, and easy to operate.

[0003] Currently, the output end of anchor drilling rigs on the market is not stable enough when moving in the drilling direction, which can easily affect drilling accuracy. In addition, the debris splashed during drilling may damage the output motor. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a flip-top rotating mechanism anchor drilling machine that solves the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a flip-top rotating mechanism anchor drill, comprising a base, a fixed seat on the side of the base, a clamping device on the inner side of the fixed seat, a limit rod fixedly connected to the top of the base, and a stabilizing drilling mechanism on the top of the base; the stabilizing drilling mechanism includes a movable seat and a drive seat, the movable seat being slidably connected to the limit rod, a drilling motor being mounted on the top of the movable seat, a rotating shaft being fixedly connected to the output shaft of the drilling motor, the drive seat being fixedly connected to the top of the base, a sprocket being mounted at the front end of the drive seat, a chain being mounted on the surface of the sprocket, and a cooling mechanism being mounted at the rear end of the movable seat.

[0007] Furthermore, the limiting rods are configured in four sets, and the diameters of the four sets of limiting rods are equal, which makes the moving seat more stable when it moves.

[0008] Furthermore, a coupling is provided at the end of the rotating shaft away from the drilling motor, and a flip cover is provided on the top of the drilling motor. The flip cover can prevent residue from splashing onto the drilling motor. The drill rod can be connected to the rotating shaft through the coupling.

[0009] Furthermore, the number of sprockets is set to four sets, and the number of chains is set to two sets. The tops of the two sets of chains are fixedly connected to the bottom of the movable seat, and the movement of one set of chains is driven by the rotation of every two sets of sprockets.

[0010] Furthermore, the cooling mechanism includes a cooling water tank, a pressure chamber, and an extrusion block. The cooling water tank is fixedly connected to the rear end of the movable seat, and the pressure chamber is fixedly connected to the top of the movable seat. A return spring is installed inside the pressure chamber, and a piston rod is slidably connected inside the pressure chamber via the return spring piston. A water suction pipe is passed through and fixedly connected to the rear end of the pressure chamber, and a water spray pipe is passed through and fixedly connected to the side of the pressure chamber. Both the water suction pipe and the water spray pipe are equipped with one-way valves. The extrusion block is fixedly connected to the surface of the rotating shaft.

The ball bearing can reduce the wear between the squeezing block and the piston rod.

[0013] This utility model has the following beneficial effects:

[0014] This utility model features a stable drilling mechanism, which allows the drive seat to rotate the sprockets when drilling is required. The rotation of the four sprockets drives the movement of two chains, which in turn moves the moving seat. Simultaneously, the drilling motor is activated, driving the rotating shaft to rotate. The rotating shaft, through a coupling, drives the drill rod to rotate, thus coordinating the drilling operation. The four sets of limit rods further stabilize the movement of the moving seat.

[0015] This utility model incorporates a cooling mechanism, which, during the drilling process, enables the drilling motor to rotate the shaft while simultaneously drawing cooling water from the cooling water tank through the cooperation of components such as the extrusion block, piston rod, and pressure chamber.

[0026] Please see Figures 1-5 This utility model is a flip-top rotating mechanism anchor drill, including a base 1, a fixed seat 2 on the side of the base 1, a clamping device 3 on the inner side of the fixed seat 2, a limit rod 4 fixedly connected to the top of the base 1, and a stable drilling mechanism 5 on the top of the base 1; the stable drilling mechanism 5 includes a movable seat 51 and a drive seat 55, the movable seat 51 is slidably connected to the limit rod 4, a drilling motor 52 is provided on the top of the movable seat 51, a rotating shaft 53 is fixedly connected to the output shaft of the drilling motor 52, the drive seat 55 is fixedly connected to the top of the base 1, a sprocket 56 is provided at the front end of the drive seat 55, a chain 57 is provided on the surface of the sprocket 56, and a cooling mechanism 6 is provided at the rear end of the movable seat 51.

[0027] As shown in the figure, there are four sets of limit rods 4, and the diameters of the four sets of limit rods 4 are equal. The four sets of limit rods 4 make the moving seat 51 more stable when it moves.

[0028] As shown in the figure, a coupling 58 is provided at the end of the rotating shaft 53 away from the drilling motor 52, and a flip cover 54 is provided on the top of the drilling motor 52. The flip cover 54 can prevent residue from splashing onto the drilling motor 52. The drill rod can be connected to the rotating shaft 53 through the coupling 58.

[0029] As shown in the figure, the number of sprockets 56 is set to four sets, and the number of chains 57 is set to two sets. The top of the two sets of chains 57 is fixedly connected to the bottom of the movable seat 51. The rotation of each pair of sprockets 56 drives one set of chains 57 to move.

[0030] As shown in the figure, the cooling mechanism 6 includes a cooling water tank 61, a pressure chamber 62, and a squeezing block 67. The cooling water tank 61 is fixedly connected to the rear end of the movable base 51, and the pressure chamber 62 is fixedly connected to the top of the movable base 51. A return spring 63 is installed inside the pressure chamber 62, and a piston rod 64 is slidably connected to the inside of the pressure chamber 62 through the return spring 63. A water suction pipe 65 is fixedly connected to the rear end of the pressure chamber 62, and a water spray pipe 66 is fixedly connected to the side of the pressure chamber 62. Both the water suction pipe 65 and the water spray pipe 66 are equipped with one-way valves. The squeezing block 67 is fixedly connected to the surface of the rotating shaft 53.

[0031] As shown in the figure, the one-way valve inside the water suction pipe 65 is unidirectionally open to the inside of the pressure chamber 62, and the end of the water suction pipe 65 away from the pressure chamber 62 is connected to the cooling water tank 61 through and fixedly. When a negative pressure is formed inside the pressure chamber 62, water will be drawn from the cooling water tank 61 through the water suction pipe 65.

[0032] As shown in the figure, the one-way valve inside the water spray pipe 66 is unidirectionally open to the outside of the pressure chamber 62. The piston rod 64 is equipped with a ball bearing at the end away from the pressure chamber 62. When the cooling water in the pressure chamber 62 is squeezed, it will be sprayed out through the water spray pipe 66. The ball bearing can reduce the wear between the squeezing block 67 and the piston rod 64.

[0033] A specific application of this embodiment is as follows: When drilling is required, the drive seat 55 drives the sprockets 56 to rotate. The rotation of the four sets of sprockets 56 drives the two sets of chains 57 to move. The movement of the chains 57 drives the moving seat 51 to move. At the same time, the drilling motor 52 is turned on, driving the rotating shaft 53 to rotate. The rotation of the rotating shaft 53 drives the drill rod to rotate through the coupling 58, thus coordinating the drilling work. The setting of the four sets of limit rods 4 makes the movement of the moving seat 51 more stable, thereby improving the overall drilling accuracy. When the drilling motor 52 is turned on, driving the rotating shaft 53 to rotate, the pressing block 67 follows the rotation of the rotating shaft 53. The piston rod 64 is repeatedly squeezed by the pressing block 67, causing it to move to the rear end. The return spring 63 is compressed, and the ball bearings reduce wear between the pressing block 67 and the piston rod 64. The rearward movement of the piston rod 64 squeezes the cooling water in the pressure chamber 62, causing it to be sprayed out through the water spray pipe 66. When the pressing block 67 leaves the piston rod 64, the return spring 63 rebounds, causing the piston rod 64 to move to the front end to return to its original position. At this time, a negative pressure is formed in the pressure chamber 62, which draws water from the cooling water tank 61 through the water suction pipe 65. This cycle continues, and by spraying water onto the drilling area, cooling and dust reduction are achieved.
