Description

Technical Field

[0001] The invention belongs to the technical field of highway construction equipment, in particular to a drilling device for highway construction. Background Art

[0002] During highway construction, in order to separate the construction area, it is necessary to build fences on the surface of the highway. Therefore, workers need to use a drilling machine to drill evenly spaced holes on the surface of the highway. Then the workers can insert poles into the holes, and then install fences on the bases of each pole.

[0003] The prior art has also proposed some solutions, such as a movable drilling machine, that is, by placing the drilling machine on a cart, workers can more conveniently move the drilling machine to a designated area using the cart, and then the workers screw the threaded pins around the cart to fix the cart, and then control the drilling machine on the cart to slowly descend to complete the drilling operation on the road surface.

[0004] In the prior art, the highway drilling device can be moved by a cart, which can facilitate workers to move the drilling machine. However, when the drilling machine is moved to the position where holes need to be drilled and before drilling, the worker needs to fix the cart to prevent the drill bit from deviating from the drilling position or being damaged due to the movement of the cart during the drilling operation. Therefore, during the batch drilling process, the worker needs to constantly turn the pin to fix and release the cart, thereby reducing work efficiency.

[0005] To this end, the present invention provides a punching device for highway construction. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a punching device for highway construction described in the present invention comprises a base plate; a pair of sliding rods are fixedly connected to the top surface of the base plate; a movable seat is slidably connected between the two sliding rods; a spindle seat is fixedly connected to one side of the movable seat; a drill bit is fixedly connected to the output shaft of the spindle seat, and the output shaft of the spindle seat is driven by an engine; a water injection assembly is installed on the top surface of the spindle seat; the water injection assembly is used to inject coolant into the drill bit; the tops of the two sliding rods are fixedly connected to a top plate; a threaded rod is rotatably connected to the top surface of the base plate at the corresponding position of the movable seat; the threaded rod is threadedly connected to the movable seat and rotatably connected to the top plate; a base is arranged on the outer side of the base plate , and the base is U-shaped; a plurality of evenly arranged rollers are installed on the outside of the base; a support frame is fixedly connected to the side of the base away from the drill bit; a pair of support rods are rotatably connected to the inside of the support frame; the rotation connection point between the support rod and the support frame divides the support rod into two parts, and the length of the support rod close to the bottom plate is shorter than the length of the part away from the bottom plate; a connecting plate is rotatably connected between one end of the support rod close to the bottom plate and the bottom plate; a locking assembly is installed at one end of the support rod away from the bottom plate; the locking assembly is used to fix the angle between the support rod and the base; when working, in order to facilitate workers to carry out continuous drilling operations on the road, the embodiment of the present invention can be used, and when the embodiment of the present invention needs to be moved, the worker needs to press down the support rod first The support rod is rotatably connected to the support frame, and the length of the support rod close to the bottom plate is shorter than the length of the support rod away from the bottom plate, so the support rod is a labor-saving lever. When the worker presses down the support rod, the support rod will lift the bottom plate through the connecting plate to make it leave the ground. Then the worker fixes the support rod through the locking assembly. At this time, the rollers at the bottom of the base are in normal contact with the bottom surface, while the bottom plate is not. Therefore, the worker can push the embodiment of the present invention normally through the support frame. After the worker pushes the embodiment of the present invention to the position where drilling is required, the worker needs to unlock the support rod through the locking assembly, so that the support rod can deflect and let the end of the support rod close to the bottom plate slowly descend so that the bottom plate can contact with the road. The rollers around the seat cannot drive the embodiment of the present invention to move at will, and then the worker can start the engine to rotate the drill bit at the spindle seat, and then screw the threaded rod at the top plate, so that the moving seat on the surface of the threaded rod descends along the surface of the sliding rod, thereby driving the spindle seat and the drill bit to descend together, so that the drill bit can complete the drilling operation on the road surface. During the drilling process, the water injection assembly will also inject coolant into the drill bit to avoid the drill bit from overheating. The support rod and the support frame form a lever structure, so that the worker can lift or lower the bottom plate more conveniently and quickly, thereby further facilitating the worker to fix or move the embodiment of the present invention, thereby simplifying the operating process and improving the worker's work efficiency.

[0008] Preferably, a pair of symmetrically arranged sliders are fixedly connected on both sides of the base plate; a side of the base close to the base plate is fixedly connected to a limiting block at a corresponding position of the slider; a limiting groove is provided on a side of the limiting block close to the slider; the slider is adapted to the limiting groove, and the slider is slidably connected to the limiting groove; during operation, when the base plate is lifted or lowered, the sliders around the base plate will slide in the sliding grooves on the surface of the limiting block, thereby limiting the horizontal movement of the base plate, so that the base plate can only move in the vertical direction, so that the base plate can be accurately placed on the ground.

[0009] Preferably, one end of the two support rods away from the connecting plate is commonly fixedly connected to a connecting rod; a sleeve is slidably connected to the surface of the connecting rod; a pedal is rotatably connected to the surface of the sleeve; when working, when the worker needs to press down the support rod, the worker can step on the pedal with his foot, and the sleeve and the connecting rod are driven down by the pedal, and then the support rod is driven down by the connecting rod to complete the operation of lifting the base plate. At the same time, when the worker is lowering the base plate, the worker still needs to step on the base plate to control the falling speed of the base plate, thereby preventing the base plate from hitting the ground quickly and causing damage to the base plate. The pedal can slide on the connecting rod through the sleeve, so the worker can slide the pedal to the side of his dominant foot, which is convenient for the worker to use.

[0010] Preferably, the locking assembly includes a hanging rod, and the hanging rod is arranged in an L shape; the hanging rod is rotatably connected to one end of the base away from the bottom plate; a stop rod is fixedly connected to the side of the two support rods close to each other; the two stop rods are symmetrically arranged, and the gap left between the two stop rods is larger than the diameter of the hanging rod; during work, when the worker lifts the bottom plate through the support rod and needs to move it through the rollers later, the worker needs to rotate the hanging rod at one end of the base so that the hanging rod is rotated to the side of any stop rod close to the bottom plate, thereby limiting the deflection of the support rod through the stop rod, and then locking the support rod. At this time, the worker does not need to continuously press down the pedal to keep the bottom plate in a lifted state. Since a pair of stop rods are provided, it is convenient for the worker to quickly lock the support rod with either hand, thereby improving the usability of the embodiment of the present invention.

[0011] Preferably, the inner walls on both sides of the base are provided with rotating grooves at corresponding positions of the bottom plate; a rotating column is rotatably connected in the rotating groove; a support rod is threadedly connected to the side of the rotating column close to the bottom plate, and the support rod is slidably connected to the base; a slot is provided at the end of the rotating column away from the support rod; a handle is inserted in the slot; during work, when the embodiment of the present invention is not used for a long time or needs to be loaded and transported, the worker can insert the handle into the slot on the end face of the rotating column, and since the rotating column is threadedly connected to the support rod, and the support rod is slidably connected to the base, the worker can drive the support rod to move toward the direction of the bottom plate by rotating the handle, and finally move it to the bottom surface of the bottom plate, at this time the bottom plate is supported by the support rod, even if the hanging rod and the baffle rod become loose during transportation, the support rod can still resist the bottom plate to prevent the bottom plate from falling directly to the ground and causing damage to the bottom plate and the components on top of it.

[0012] Preferably, the base is a hollow structure; a transmission rod is provided on one side of the two rotating columns close to the support frame; the transmission rod is rotatably connected to the inside of the base and is connected to the rotating column through a gear set; a rotating rod is provided between the two transmission rods and at one end away from the rotating column; the rotating rod is rotatably connected to the inside of the base, and both ends of the rotating rod are connected to the transmission rod through a gear set; during work, when a worker rotates the rotating column on one side, the rotating column on that side will drive the transmission rod on that side to rotate through the gear set, and the transmission rod will drive the rotating rod to rotate through the gear set, and finally the rotating rod will drive the transmission rod on the other side to rotate through the gear set, and then the transmission rod on the other side will drive the rotating column on the other side to rotate through the gear set, so that only rotating one side of the rotating column can also drive the support columns on both sides to move to the bottom surface of the base plate, thereby avoiding the worker from rotating the rotating columns on both sides separately, thereby reducing the operation difficulty of the worker and improving the ease of use of the embodiment of the present invention.

[0013] Preferably, a rotating seat is rotatably connected to the top surface of one side of the base near the drill bit position; a knocking rod is rotatably connected to the top surface of the rotating seat; a spring is fixedly connected between the knocking rod and the rotating seat; during operation, during the drilling process, when gravel is stuck inside the drill bit, the worker needs to lift the drill bit first, and then rotate the rotating seat so that the knocking rod on the top of the rotating seat faces the drill bit, and then the worker lifts one end of the knocking rod away from the drill bit and compresses the spring, so that the end of the knocking rod close to the drill bit can be knocked on the surface of the drill bit, and then the worker lets go, and the compressed spring recovers, thereby driving the knocking rod to reset, and then the worker repeatedly lifts and releases the knocking rod to achieve continuous knocking on the surface of the drill bit, so that the stone stuck inside the drill bit can be loosened and fall out of the drill bit.

[0014] Preferably, the top surface of the rotating seat is rotatably connected with a support plate; the support plate is located in the vertical direction of the knocking rod, and the end of the support plate close to the knocking rod is located at the bottom of the knocking rod; a second spring is fixedly connected between the end of the support plate close to the knocking rod and the rotating seat; during work, when the worker needs to move the knocking rod, the worker can step on the support plate away from the end of the knocking rod, at this time the second spring is stretched, and the end of the support plate close to the knocking rod will be lifted up, thereby lifting the end of the knocking rod away from the drill bit, and then causing the end of the knocking rod close to the drill bit to knock on the surface of the drill bit, and when the worker does not step on the support plate, the stretched second spring is restored, and the support plate is driven to restore, and at this time the knocking rod will also be reset under the action of the first spring, so that the worker no longer needs to bend over to move the knocking rod, thereby improving the comfort of using this embodiment.

[0015] Preferably, one end of the knocking rod away from the top plate is threadedly connected to the extension rod; an elastic ball is fixedly connected to one end of the extension rod away from the knocking rod; during work, when using drill bits of different diameters, the worker also needs to screw the extension rod so that the elastic ball at the end of the extension rod can just touch the surface of the drill bit, so that the knocking rod can normally knock the drill bit through the extension rod, and the elastic ball can also avoid scratching the drill bit, thereby improving the scope of application of the embodiment of the present invention.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figure 1 to Figure 2As shown, a punching device for highway construction described in an embodiment of the present invention comprises a base plate 1; a pair of sliding rods 2 are fixedly connected to the top surface of the base plate 1; a moving seat 3 is slidably connected between the two sliding rods 2; a spindle seat 4 is fixedly connected to one side of the moving seat 3; a drill bit 5 is fixedly connected to the output shaft of the spindle seat 4, and the output shaft of the spindle seat 4 is driven by an engine; a water injection assembly is installed on the top surface of the spindle seat 4; the water injection assembly is used to inject coolant into the drill bit 5; the tops of the two sliding rods 2 are fixedly connected to a top plate 6; a threaded rod 7 is rotatably connected to the top surface of the base plate 1 at a corresponding position of the moving seat 3; the threaded rod 7 is threadedly connected to the moving seat 3 and is rotatably connected to the top plate 6 The bottom plate 1 is provided with a base 8 on its outer side, and the base 8 is U-shaped; a plurality of evenly arranged rollers 9 are installed on the outer side of the base 8; a support frame 10 is fixedly connected to the side of the base 8 away from the drill bit 5; a pair of support rods 11 are rotatably connected to the inner side of the support frame 10; the rotation connection point between the support rod 11 and the support frame 10 divides the support rod 11 into two parts, and the length of the part of the support rod 11 close to the bottom plate 1 is less than the length of the part away from the bottom plate 1; a connecting plate 12 is rotatably connected between the end of the support rod 11 close to the bottom plate 1 and the bottom plate 1; a locking assembly is installed at the end of the support rod 11 away from the bottom plate 1; the locking assembly is used to fix the angle between the support rod 11 and the base 8;During work, in order to facilitate workers to perform continuous drilling operations on the road, the embodiment of the present invention can be used. When the embodiment of the present invention needs to be moved, the worker needs to first press down the end of the support rod 11 away from the bottom plate 1. Since the support rod 11 is rotatably connected to the support frame 10, and the length of the part of the support rod 11 close to the bottom plate 1 is less than the length of the part away from the bottom plate 1, the support rod 11 is a labor-saving lever. When the worker presses down the support rod 11, the support rod 11 will lift the bottom plate 1 off the ground through the connecting plate 12, and then the worker fixes the support rod 11 through the locking assembly. At this time, the roller 9 at the bottom of the base 8 is normally in contact with the bottom surface, while the bottom plate 1 is not. Therefore, the worker can push the embodiment of the present invention normally through the support frame 10. After the worker pushes the embodiment of the present invention to the position where drilling is required, the worker needs to unlock the support rod 11 through the locking assembly so that the support rod 11 can deflect. The end of the support rod 11 close to the bottom plate 1 is slowly lowered so that the bottom plate 1 can contact the road. At this time, the rollers 9 around the base 8 cannot drive the embodiment of the present invention to move at will. Then the worker can start the engine to rotate the drill bit 5 at the spindle seat 4, and then screw the threaded rod 7 at the top plate 6, so that the moving seat 3 on the surface of the threaded rod 7 descends along the surface of the slide bar 2, thereby driving the spindle seat 4 and the drill bit 5 to descend together, so that the drill bit 5 can complete the drilling operation on the road surface. During the drilling process, the water injection component will also inject coolant into the drill bit 5 to prevent the temperature of the drill bit 5 from being too high. The support rod 11 and the support frame 10 form a lever structure, so that the worker can lift or put down the bottom plate 1 more conveniently and quickly, thereby further facilitating the worker to fix or move the embodiment of the present invention, thereby simplifying the operation process and improving the work efficiency of the worker. ;

[0031] like Figures 1 to 3 As shown, a pair of symmetrically arranged sliders 13 are fixedly connected on both sides of the base plate 1; a side of the base 8 close to the base plate 1 is fixedly connected to a limiting block 14 at a position corresponding to the slider 13; a limiting groove 15 is provided on the side of the limiting block 14 close to the slider 13; the slider 13 is adapted to the limiting groove 15, and the slider 13 is slidably connected to the limiting groove 15; during operation, when the base plate 1 is lifted or lowered, the sliders 13 around the base plate 1 will slide in the sliding grooves on the surface of the limiting block 14, thereby limiting the horizontal movement of the base 8, so that the base plate 1 can only move in the vertical direction, so that the base plate 1 can be accurately placed on the ground.

[0032] like Figure 1 , Figure 2 and Figure 4As shown, one end of the two support rods 11 away from the connecting plate 12 is commonly fixedly connected with a connecting rod 16; the surface of the connecting rod 16 is slidably connected with a sleeve 17; the surface of the sleeve 17 is rotatably connected with a pedal 18; during work, when the worker needs to press down the support rod 11, the worker can step on the pedal 18 with his foot, and the sleeve 17 and the connecting rod 16 are driven down by the pedal 18, and then the support rod 11 is driven down by the connecting rod 16 to complete the operation of lifting the base plate 1. At the same time, when the worker is putting down the base plate 1, the worker still needs to step on the base plate 1 to control the falling speed of the base plate 1, thereby preventing the base plate 1 from quickly hitting the ground and causing damage to the base plate 1, and the pedal 18 can slide on the connecting rod 16 through the sleeve 17, so the worker can slide the pedal 18 to the side of his dominant foot, thereby facilitating the worker's use.

[0033] like Figure 1 to Figure 2 As shown, the locking assembly includes a hanging rod 19, and the hanging rod 19 is arranged in an L shape; the hanging rod 19 is rotatably connected to the end of the base 8 away from the bottom plate 1; the two sides of the support rods 11 close to each other are fixedly connected with a blocking rod 20; the two blocking rods 20 are symmetrically arranged, and the gap left between the two blocking rods 20 is larger than the diameter of the hanging rod 19; during work, when the worker lifts the bottom plate 1 through the support rod 11, and subsequently needs to move it through the roller 9, the worker needs to rotate the hanging rod 19 at one end of the base 8 so that the hanging rod 19 is rotated to the side of any blocking rod 20 close to the bottom plate 1, thereby limiting the deflection of the support rod 11 through the blocking rod 20, and then locking the support rod 11. At this time, the worker does not need to continuously press the pedal 18 to keep the bottom plate 1 in a lifted state. Since a pair of blocking rods 20 are provided, it is convenient for the worker to quickly lock the support rod 11 with either hand, thereby improving the ease of use of the embodiment of the present invention.

[0034] like Figure 3 and Figure 5As shown, the inner walls of both sides of the base 8 are provided with rotation grooves 21 at positions corresponding to the bottom plate 1; a rotation column 22 is rotatably connected in the rotation groove 21; a support rod 23 is threadedly connected to the side of the rotation column 22 close to the bottom plate 1, and the support rod 23 is slidably connected to the base 8; a slot 24 is provided at one end of the rotation column 22 away from the support rod 23; a handle 25 is inserted into the slot 24; during operation, when the embodiment of the present invention is not used for a long time or needs to be loaded and transported, a worker can insert the handle 25 into the rotation column 2 2, and since the rotating column 22 is threadedly connected to the support rod 23, and the support rod 23 is slidably connected to the base 8, the worker can drive the support rod 23 to move toward the bottom plate 1 by rotating the handle 25, and finally move it to the bottom surface of the bottom plate 1. At this time, the bottom plate 1 is supported by the support rod 23. Even if the hanging rod 19 and the blocking rod 20 become loose during transportation, the support rod 23 can still support the bottom plate 1 to prevent the bottom plate 1 from falling directly to the ground and causing damage to the bottom plate 1 and the components on top of it.

[0035] like Figure 5 As shown, the base 8 is a hollow structure; a transmission rod 26 is provided on one side of the two rotating columns 22 close to the support frame 10; the transmission rod 26 is rotatably connected to the inside of the base 8, and is connected to the rotating column 22 through a gear set; a rotating rod 27 is provided between the two transmission rods 26 and at one end away from the rotating column 22; the rotating rod 27 is rotatably connected to the inside of the base 8, and both ends of the rotating rod 27 are connected to the transmission rod 26 through a gear set; when working, when a worker rotates the rotating column 22 on one side, the rotating column 22 on that side will The transmission rod 26 on that side is driven to rotate by the gear set, and the transmission rod 26 in turn drives the rotating rod 27 to rotate through the gear set, and finally the rotating rod 27 drives the transmission rod 26 on the other side to rotate through the gear set, and then the transmission rod 26 on the other side drives the rotating column 22 on the other side to rotate through the gear set, so that only the rotating column 22 on one side is rotated, and the support columns on both sides can be driven to move to the bottom surface of the base plate 1, thereby avoiding the workers from rotating the rotating columns 22 on both sides separately, thereby reducing the difficulty of operation for workers and improving the usability of the embodiments of the present invention.

[0036] like Figure 1 to Figure 2As shown, a rotating seat 28 is rotatably connected to the top surface of one side of the base 8 near the drill bit 5; a knocking rod 29 is rotatably connected to the top surface of the rotating seat 28; a spring 30 is fixedly connected between the knocking rod 29 and the rotating seat 28; during operation, during the drilling process, when gravel is stuck inside the drill bit 5, the worker needs to lift the drill bit 5 first, and then rotate the rotating seat 28 so that the knocking rod 29 on the top of the rotating seat 28 faces the drill bit 5, and then the worker lifts the knocking rod 29 away from one end of the drill bit 5 and compresses the spring 30, so that the end of the knocking rod 29 close to the drill bit 5 can be knocked on the surface of the drill bit 5, and then the worker lets go, and the compressed spring 30 recovers, thereby driving the knocking rod 29 to reset, and then the worker repeatedly lifts and releases the knocking rod 29, so as to achieve continuous knocking on the surface of the drill bit 5, so that the stone stuck inside the drill bit 5 can be loosened and fall out of the drill bit 5.

[0037] like Figure 1 , Figure 2 and Figure 6 As shown, the top surface of the rotating seat 28 is rotatably connected with a support plate 31; the support plate 31 is located in the vertical direction of the knocking rod 29, and the end of the support plate 31 close to the knocking rod 29 is located at the bottom of the knocking rod 29; a spring 2 32 is fixedly connected between the end of the support plate 31 close to the knocking rod 29 and the rotating seat 28; during work, when the worker needs to move the knocking rod 29, the worker can step on the support plate 31 away from the end of the knocking rod 29 with his foot. At this time, the spring 2 32 is stretched, and the end of the support plate 31 close to the knocking rod 29 will be lifted, thereby lifting the end of the knocking rod 29 away from the drill bit 5, and then causing the end of the knocking rod 29 close to the drill bit 5 to knock on the surface of the drill bit 5, and when the worker does not step on the support plate 31, the stretched spring 2 32 is restored, and the support plate 31 is driven to restore. At this time, the knocking rod 29 will also be reset under the action of the spring 1 30, so that the worker no longer needs to bend over to move the knocking rod 29, thereby improving the comfort of this embodiment when used.

[0038] like Figure 6 As shown, the end of the knock rod 29 away from the top plate 6 is threadedly connected to the extension rod 33; the end of the extension rod 33 away from the knock rod 29 is fixedly connected with an elastic ball 34; during work, when using drill bits 5 of different diameters, the worker also needs to screw the extension rod 33 so that the elastic ball 34 at the end of the extension rod 33 can just touch the surface of the drill bit 5, so that the knock rod 29 can normally knock the drill bit 5 through the extension rod 33, and the elastic ball 34 can also avoid scratching the drill bit 5, thereby improving the scope of application of the embodiment of the present invention.

[0039] like Figure 1 , Figure 2 and Figure 7As shown, a positioning rod 35 is rotatably connected to the bottom surface of the base 8 away from the rotating seat 28; a baffle 36 is fixedly connected to the bottom surface of the base 8 on one side of the positioning rod 35; a laser lamp 37 is fixedly connected to the end of the positioning rod 35 away from the base 8; the irradiation direction of the laser lamp 37 is toward the ground; during work, when the worker needs to align the drill bit 5 with the drilling position, the worker can rotate the positioning rod 35 so that the surface of the positioning rod 35 fits the surface of the baffle 36. At this time, the positioning rod 35 is vertically arranged to one side of the base 8, and the laser lamp 37 at the end of the positioning rod 35 is just on the axis of the spindle seat 4, which is also on the axis of the drill bit 5. At this time, the worker turns on the laser lamp 37, and the bright spot it irradiates on the ground can assist the worker in accurately locating the drilling point.

[0040] During work, in order to facilitate workers to perform continuous drilling operations on the road, the embodiment of the present invention can be used. When the embodiment of the present invention needs to be moved, the worker needs to first press down the end of the support rod 11 away from the bottom plate 1. Since the support rod 11 is rotatably connected to the support frame 10, and the length of the part of the support rod 11 close to the bottom plate 1 is less than the length of the part away from the bottom plate 1, the support rod 11 is a labor-saving lever. When the worker presses down the support rod 11, the support rod 11 will lift the bottom plate 1 off the ground through the connecting plate 12, and then the worker fixes the support rod 11 through the locking assembly. At this time, the roller 9 at the bottom of the base 8 is normally in contact with the bottom surface, while the bottom plate 1 is not. Therefore, the worker can push the embodiment of the present invention normally through the support frame 10. After the worker pushes the embodiment of the present invention to the position where drilling is required, the worker needs to unlock the support rod 11 through the locking assembly so that the support rod 11 can deflect. The end of the support rod 11 close to the bottom plate 1 is slowly lowered so that the bottom plate 1 can contact the road. At this time, the rollers 9 around the base 8 cannot drive the embodiment of the present invention to move at will. Then the worker can start the engine to rotate the drill bit 5 at the spindle seat 4, and then screw the threaded rod 7 at the top plate 6, so that the moving seat 3 on the surface of the threaded rod 7 descends along the surface of the sliding rod 2, thereby driving the spindle seat 4 and the drill bit 5 to descend together, so that the drill bit 5 can complete the drilling operation on the road surface. During the drilling process, the water injection component will also inject coolant into the drill bit 5 to avoid the temperature of the drill bit 5 being too high. The support rod 11 and the support frame 10 form a lever structure, so that the worker can lift or put down the bottom plate 1 more conveniently and quickly, thereby further facilitating the worker to fix or move the embodiment of the present invention, thereby simplifying the operation process and improving the work efficiency of the workers.

[0041] When the base plate 1 is lifted or lowered, the sliders 13 around the base plate 1 will slide in the slide grooves on the surface of the limit blocks 14, thereby limiting the horizontal movement of the base 8, so that the base plate 1 can only move in the vertical direction, so that the base plate 1 can be accurately placed on the ground.

[0042] When the worker needs to press down the support rod 11, the worker can step on the pedal 18 with his foot, and the pedal 18 drives the sleeve 17 and the connecting rod 16 to descend, and then the connecting rod 16 drives the support rod 11 to descend, so as to complete the operation of lifting the base plate 1. At the same time, when the worker is putting down the base plate 1, the worker still needs to step on the base plate 1 to control the falling speed of the base plate 1, thereby preventing the base plate 1 from hitting the ground quickly and causing damage to the base plate 1. The pedal 18 can slide on the connecting rod 16 through the sleeve 17, so the worker can slide the pedal 18 to the side of his dominant foot, which is convenient for the worker to use.

[0043] When the worker lifts the base plate 1 by the support rod 11 and needs to move it by the roller 9 later, the worker needs to rotate the hanging rod 19 at one end of the base 8 so that the hanging rod 19 is rotated to the side of any baffle rod 20 close to the base plate 1, thereby limiting the deflection of the support rod 11 by the baffle rod 20 and then locking the support rod 11. At this time, the worker does not need to continuously press down the pedal 18 to keep the base plate 1 in the lifted state. Since a pair of baffle rods 20 are provided, it is convenient for the worker to quickly lock the support rod 11 with either hand, thereby improving the usability of the embodiment of the present invention.

[0044] When the embodiment of the present invention is not used for a long time, or needs to be loaded and transported, the worker can insert the handle 25 into the slot 24 on the end face of the rotating column 22. Since the rotating column 22 is threadedly connected to the support rod 23, and the support rod 23 is slidably connected to the base 8, the worker can drive the support rod 23 to move toward the bottom plate 1 by rotating the handle 25, and finally move it to the bottom surface of the bottom plate 1. At this time, the bottom plate 1 is supported by the support rod 23. Even if the hanging rod 19 and the blocking rod 20 become loose during transportation, the support rod 23 can still support the bottom plate 1 to prevent the bottom plate 1 from falling directly to the ground and causing damage to the bottom plate 1 and the components on top of it.

[0045] When a worker rotates the rotating column 22 on one side, the rotating column 22 on that side will drive the transmission rod 26 on that side to rotate through the gear set, and the transmission rod 26 will drive the rotating rod 27 to rotate through the gear set, and finally the rotating rod 27 will drive the transmission rod 26 on the other side to rotate through the gear set, and then the transmission rod 26 on the other side will drive the rotating column 22 on the other side to rotate through the gear set, so that only rotating one side of the rotating column 22 can be rotated, and the supporting columns on both sides can be driven to move to the bottom surface of the base plate 1, thereby avoiding the workers from rotating the rotating columns 22 on both sides separately, thereby reducing the difficulty of operation for workers and improving the usability of the embodiments of the present invention.

[0046] During the drilling process, when gravel is stuck inside the drill bit 5, the worker needs to lift the drill bit 5 first, and then rotate the rotating seat 28 so that the knocking rod 29 on the top of the rotating seat 28 faces the drill bit 5, and then the worker lifts the knocking rod 29 away from one end of the drill bit 5, and compresses the spring 30, so that the end of the knocking rod 29 close to the drill bit 5 can be knocked on the surface of the drill bit 5, and then the worker lets go, and the compressed spring 30 recovers, thereby driving the knocking rod 29 to reset, and then the worker repeatedly lifts and releases the knocking rod 29, so as to continuously knock on the surface of the drill bit 5, so that the stone stuck inside the drill bit 5 can be loosened and fall out of the drill bit 5.

[0047] When the worker needs to move the knocking rod 29, the worker can step on the end of the support plate 31 away from the knocking rod 29. At this time, the spring 2 32 is stretched, and the end of the support plate 31 close to the knocking rod 29 will be lifted, thereby lifting the end of the knocking rod 29 away from the drill bit 5, and then the end of the knocking rod 29 close to the drill bit 5 knocks on the surface of the drill bit 5. When the worker does not step on the support plate 31, the stretched spring 2 32 recovers and drives the support plate 31 to recover. At this time, the knocking rod 29 will also be reset under the action of the spring 1 30, so that the worker no longer needs to bend over to move the knocking rod 29, thereby improving the comfort of this embodiment when used.

[0048] When using drill bits 5 of different diameters, workers also need to screw the extension rod 33 so that the elastic ball 34 at the end of the extension rod 33 can just touch the surface of the drill bit 5, so that the knocking rod 29 can normally knock the drill bit 5 through the extension rod 33, and the elastic ball 34 can also avoid scratching the drill bit 5, thereby improving the scope of application of the embodiment of the present invention.

[0049] When the worker needs to align the drill bit 5 with the drilling position, the worker can rotate the positioning rod 35 so that the surface of the positioning rod 35 fits against the surface of the baffle 36. At this time, the positioning rod 35 is vertically arranged to one side of the base 8, and the laser lamp 37 at the end of the positioning rod 35 is just on the axis of the spindle seat 4, which is also the axis of the drill bit 5. At this time, the worker turns on the laser lamp 37, and the bright spot it illuminates on the ground can assist the worker in accurately locating the drilling point.
