DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 8 The present invention provides a technical solution: a construction safety protection device, comprising a freely lifting top platform 1 and a base 2 arranged on the top platform 1 for supporting a drilling machine 3, and also comprising a water tank for receiving water, the drilling machine 3 is provided with a detachably connected drill bit, and the base 2 is provided with a protective structure for protecting the drilling machine 3 when drilling holes on concrete components; The protective structure includes a horizontal seat 5 which is arranged on the base 2 and can move freely in the horizontal direction. The horizontal seat 5 is provided with a moving assembly which drives the drilling machine 3 to always contact the concrete during the drilling process. The end of the drilling machine 3 away from the top platform 1 is fixedly connected with two sets of side plates 18. The side plate 18 is provided with a protective component to prevent the debris generated by the drill bit during the drilling process from splashing randomly. The protective component includes a baffle 19 arranged on the side plate 18. The baffle 19 is fixedly rotated on the side plate 18 and can swing freely in the vertical direction. The side plate 18 is provided with a plurality of nozzles 36 , and the drilling machine 3 is provided with a dust reduction component for driving the water source in the water tank to spray from the nozzles 36 toward the concrete.

[0022] like Figure 1 , Figure 2 and Figure 5 As shown, when drilling a concrete component, the horizontal height of the top platform 1 is adjusted to drive the drilling machine 3 set on the base 2 to correspond to the position to be drilled. After the staff confirms the drilling point, the rotating drill bit is driven toward the concrete component through the abutment assembly, and during the drilling process, the drilling machine 3 always has a certain squeezing force with the concrete component, thereby ensuring the stability of the drilling process, and through the squeezing force, the drill bit can drill into the concrete component more efficiently, so as to achieve the purpose of increasing the drilling speed and shortening the construction time.

[0023] At the same time, in the initial state, there is a certain distance between the drill bit and the concrete component, and the distance is reduced to facilitate the staff to determine the drilling point. At the same time, during the drilling process, the drilling machine 3 moves horizontally toward the concrete component and finally contacts the concrete component. During this process, the movement of the drilling machine 3 can drive the protection component to operate to drive the baffle 19 on the side plate 18 to stand up, thereby preventing the drilling machine 3 from generating gravel during the drilling process. The baffle 19 can be automatically deployed before the drill bit contacts the concrete component, which is more convenient to use. When the baffle 19 is retracted, it is in a horizontal state, thereby avoiding the problem of obstructing the staff's line of sight and will not affect the staff's observation and determination of the drilling point.

[0024] Furthermore, during the drilling process, driven by the dust reduction assembly, the water in the water tank is sprayed onto the concrete member through multiple groups of nozzles 36 provided on the side plate 18. Before the drill bit contacts the concrete member, spraying water on the drilling point in the concrete member can reduce loose debris on its surface, enhance the density of the surface, and thus improve the stability in the initial stage of drilling.

[0025] At the same time, when the drill bit drills into the concrete component, the drill bit will generate a lot of heat during the high-speed rotation and drilling process. Therefore, the water source sprayed by the nozzle 36 can effectively reduce the temperature of the drill bit to ensure the service life of the drill bit. At the same time, water sprinkling can lubricate the contact surface between the drill bit and the concrete, reduce friction resistance, and make the drill bit drill into the concrete more smoothly, thereby improving the speed and quality of drilling. In addition, a large amount of concrete dust will be generated during the drilling process. Sprinkling water can inhibit the diffusion of dust and reduce the dust concentration in the air, thereby ensuring the air quality at the construction site.

[0026] In one of the more preferred embodiments, the protection assembly further comprises an L-shaped support seat 16 disposed on the base 2, the drilling machine 3 is fixedly connected to the L-shaped support seat 16, and a transverse through groove 17 is provided on the base 2 for the L-shaped support seat 16 to slide horizontally; The side plate 18 is provided with a level seat 21 and a rectangular groove for the level seat 21 to slide horizontally. The level seat 21 is provided with a freely swinging positioning column 20. Both ends of the positioning column 20 include an integrally formed ball head. The level seat 21 and the baffle 19 are fixedly connected with a ball head seat 22 for the ball head to roll on.

[0027] A special-shaped bottom plate 23 fixedly connected to the L-shaped support seat 16 is provided below the base 2, a positioning pin 24 is fixedly connected to one end of the horizontal seat 21 facing the special-shaped bottom plate 23, and a positioning groove 25 for the positioning pin 24 to slide and connect is opened on the special-shaped bottom plate 23, and the positioning groove 25 includes an integrally formed oblique groove portion 251 and a straight groove portion 252.

[0028] like Figure 2 , Figure 4 and Figure 8 As shown, when the L-shaped support seat 16 drives the drilling machine 3 to move in the horizontal direction toward the position of the concrete component, it can drive the special-shaped base plate 23 below to move horizontally synchronously, wherein, in the initial state, the positioning pin 24 is at one end of the inclined groove portion 251 away from the straight groove portion 252, and when the special-shaped base plate 23 is moving, it can first drive the positioning pin 24 to slide on the inclined groove portion 251, and then change the horizontal position of the level seat 21 through the positioning pin 24, wherein a positioning column 20 is provided between the level seat 21 and the baffle 19, and the end positions of the positioning columns 20 of both are fixedly connected with ball head seats 22, therefore, when the horizontal position of the level seat 21 changes, it can drive the positioning column 20 to deflect, and then drive the baffle 19 to rotate on the side plate 18, so that the angle between the baffle 19 and the horizontal plane gradually increases, so that it is in an upright state.

[0029] It should be noted that with the subsequent horizontal movement of the L-shaped support seat 16, the positioning pin 24 corresponds to the position of the straight groove portion 252 and slides on the straight groove portion 252. Therefore, during this process, the horizontal position of the horizontal seat 21 will not change, and then the baffle 19 will not deflect during the drilling process after being in the upright state, thereby ensuring that the baffle 19 can prevent the stones generated by drilling from splashing randomly.

[0030] Based on the embodiment of the protection component, the abutment component includes a threaded rod 4 that rotates on a fixed axis on a base 2, and an internal threaded cylinder 7 that rotates on a fixed axis on a horizontal seat 5 and is threadedly connected to the threaded rod 4; The horizontal seat 5 is provided with a receiving groove, and a corresponding plate 9 is slidably connected in the receiving groove. The internal threaded tube 7 is provided with a corresponding groove 8 corresponding to the corresponding plate 9. A pressure spring 10 is provided in the receiving groove. The two ends of the pressure spring 10 are respectively fixedly connected to the corresponding plate 9 and the horizontal seat 5. The horizontal seat 5 is provided with a locking component for driving the corresponding plate 9 to disengage from the corresponding groove 8. A plurality of guide posts 6 are slidably passed through the transverse seat 5 , and both ends of the guide posts 6 are fixedly connected to the base 2 .

[0031] The locking assembly includes a traverse plate 12 arranged on the traverse seat 5, a yield pin 11 is fixedly connected to one end of the same position plate 9 facing the traverse plate 12, and an oblique yield groove 13 for the yield pin 11 to be slidably connected is provided on the traverse plate 12, and a groove body 1 for the traverse plate 12 to be slidably connected is provided on the traverse seat 5; The end of the traverse plate 12 facing the L-shaped support seat 16 is fixedly connected with a connecting rod 14 , and the end of the connecting rod 14 facing the L-shaped support seat 16 is provided with a push plate 15 abutting against it.

[0032] The L-shaped support seat 16 is located at one end close to the top platform 1 and is not in contact with the push plate 15 in an initial state.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, in the initial state, under the action of the elastic potential energy of the compression spring 10, the isotropic plate 9 is in the isotropic groove 8. When the threaded rod 4 rotates freely in the vertical direction, due to the restriction of the guide column 6, the transverse seat 5 will not rotate in the vertical direction with the threaded rod 4. Therefore, driven by the threaded rod 4, the transverse seat 5 can be driven by the internal threaded tube 7 to move in the horizontal direction toward the L-shaped support seat 16.

[0034] At the same time, with the horizontal movement of the transverse seat 5, the distance between the push plate 15 and the L-shaped support seat 16 gradually decreases, and finally the push plate 15 contacts the L-shaped support seat 16. With the continuous rotation of the transverse seat 5, the push plate 15 can push the L-shaped support seat 16 to move horizontally, so as to drive the drilling machine 3 on the L-shaped support seat 16 to move toward the concrete component, and finally make the drill bit thereon contact with the concrete component.

[0035] Moreover, after the drill bit contacts the concrete member, the push plate 15, the connecting rod 14 and the oblique giving way groove 13 cannot continue to move horizontally. However, at this time, the threaded rod 4 is still in a rotating state. Therefore, a relative displacement movement occurs between the traverse plate 12 and the transverse seat 5, thereby driving the giving way pin 11 to slide on the oblique giving way groove 13 provided on the traverse plate 12, so that the giving way pin 11 can drive the same position plate 9 to move in the vertical direction, and drive the pressure spring 10 to undergo compression deformation, and at the same time, cause the same position plate 9 to disengage from the same position groove 8. At this time, when the threaded rod 4 rotates, since the internal threaded tube 7 is no longer restricted by the same position plate 9, the internal threaded tube 7 will rotate synchronously with the threaded rod 4 and can no longer drive the transverse seat 5 to move horizontally.

[0036] At the same time, due to the compression deformation of the pressure spring 10, a downward force is generated on the isotropic plate 9, and then a horizontal force is generated on the traverse plate 12 through the give way pin 11 and the oblique give way groove 13, and the drilling machine 3 is subjected to a horizontal extrusion force through the transmission of the connecting rod 14, the push plate 15 and the L-shaped support seat 16. At the same time, since the drill bit rotates at high speed during this process, the drill bit can drill into the concrete component under the extrusion force.

[0037] Moreover, as the drill bit drills forward, the traverse plate 12, the connecting rod 14 and the L-shaped support seat 16 can move a certain distance in the horizontal direction as the drilling process progresses due to the extrusion force, thereby driving the clearance pin 11 to slide a certain distance on the inclined clearance groove 13, so that the pressure spring 10 can restore part of the compression deformation. As the drilling process continues, the pressure spring 10 can completely restore the deformation and prompt the isotropic plate 9 to re-enter the isotropic groove 8 to complete the restriction of the internal threaded tube 7.

[0038] Therefore, when the subsequent threaded rod 4 continues to rotate, it can drive the horizontal seat 5 to move a certain distance in the horizontal direction again, until the traverse plate 12 is relatively deformed with the horizontal seat 5 again, prompting the isotropic plate 9 to disengage from the isotropic groove 8 again, thereby causing the pressure spring 10 to be compressed and deformed again to apply an extrusion force to the drilling machine 3.

[0039] It should be noted that, in actual use, the threaded rod 4 rotates continuously, so during drilling, it can drive the horizontal seat 5 to move until the pressure spring 10 applies the maximum extrusion force to the drilling machine 3, the horizontal seat 5 will stop moving, and under the action of the pressure spring 10, the drill bit gradually penetrates into the concrete component and completes the release of the extrusion force until the pressure spring 10 recovers its elastic deformation, and after the pressure spring 10 recovers its deformation, the rotation process of the threaded rod 4 again drives the horizontal seat 5 to move horizontally a certain distance, so as to prompt the pressure spring 10 to apply an extrusion force to the drilling machine 3 again, and through the reciprocating horizontal movement process of the horizontal seat 5 and the extrusion force application and release process of the pressure spring 10, the drilling process of the concrete component is completed.

[0040] Based on the embodiment of the abutment assembly, the dust reduction assembly includes a water cylinder 26 fixedly connected to the base 2, the inner wall of the water cylinder 26 is in sliding contact with a piston plate 27 that can move freely in the horizontal direction, and a water outlet pipe 34 and a water inlet pipe 35 are fixedly passed through the water cylinder 26. The end of the water inlet pipe 35 away from the water cylinder 26 is fixedly passed through the water tank, and the end of the water outlet pipe 34 away from the water cylinder 26 is fixedly passed through multiple groups of branch pipes, the nozzle 36 is fixedly passed through the branch pipe, and the branch pipe is fixedly connected to the side plate 18.

[0041] A U-shaped bracket 33 is fixedly connected to the bottom of the base 2, and a connecting rod 30 that is fixedly rotated on the U-shaped bracket 33 and is transmission-connected to the threaded rod 4, and one end of the connecting rod 30 away from the U-shaped bracket 33 is fixedly connected to a limit pin 31, and a traverse column 28 is fixedly connected to the piston plate 27, and an end rocker rod 29 is fixedly connected to the end of the traverse column 28 away from the piston plate 27, and a limit groove 32 for the limit pin 31 to slide and connect is provided on the end rocker rod 29.

[0042] like Figure 2 , Figure 5 and Figure 6 As shown, when the threaded rod 4 rotates horizontally, it can drive the connecting rod 30 connected thereto to rotate in the horizontal direction, wherein a limit pin 31 is fixedly provided on the connecting rod 30, and a limit groove 32 for the limit pin 31 to be slidably connected is provided on the end rocker arm 29. Therefore, when the connecting rod 30 rotates horizontally, the horizontal position of the end rocker arm 29 can be changed by the limit pin 31, thereby driving the end rocker arm 29 and the transverse moving column 28 fixed thereon to perform reciprocating motion in the horizontal direction.

[0043] At the same time, a piston plate 27 fixedly arranged at the end of the transverse moving column 28 is slidably arranged on the inner wall of the water cylinder 26. The reciprocating motion of the piston plate 27 in the water cylinder 26 can suck the water in the water tank or discharge the water in the water cylinder 26. The piston plate 27 is fixedly connected with multiple groups of branch pipes through the water outlet pipe 34. Therefore, the water in the water cylinder 26 can flow to the nozzle 36 through the water outlet pipe 34 and the branch pipe, and be sprayed out through the positions of the multiple groups of nozzles 36, thereby cooling the drill bit position and suppressing the dust generated during drilling to reduce the dust concentration in the air, thereby ensuring the air quality at the construction site.

[0044] It should be noted that a set of one-way valves are respectively provided on the water inlet pipe 35 and the water outlet pipe 34, and the valve ports of the two sets of one-way valves are facing opposite directions. Therefore, by setting the two sets of one-way valves, the flow direction of the water source can be restricted, so that the water source can only flow into the water cylinder 26 through the water tank, and then pass through the water cylinder 26 to the nozzle 36, and finally spray out.

[0045] In addition, the connecting rod 30 is connected to the threaded rod 4 by transmission, wherein the threaded rod 4 rotates in the vertical direction and the connecting rod 30 rotates in the horizontal direction. Therefore, in actual use, the rotation direction of the transmission shaft can be changed by the meshing of two or more sets of bevel gears, and the rotation speed of the shaft rotating in the same direction can be changed by components such as transmission wheels, thereby ensuring that the connecting rod 30 and the threaded rod 4 can rotate synchronously.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
