Description

Technical Field

[0001] The invention relates to the technical field of building drilling, and in particular to a reinforcement embedding drilling device for a structural column reinforcement at the bottom of a beam. Background Art

[0002] During the construction of masonry structural columns, the pre-embedded structural column steel bars at the bottom of the beam are very cumbersome and involve template opening, which is a complicated process. Therefore, the construction often adopts the method of drilling and embedding steel bars in the later stage to retain the structural column steel bars at the bottom of the beam. Since the structural column at the bottom of the beam is higher than the ground, a reinforcement embedding drilling device for the structural column steel bars at the bottom of the beam is required for auxiliary drilling.

[0003] However, the existing beam bottom structural column reinforcement planting drilling device still has the following defects during use:

[0004] 1. Although the existing rebar embedding drilling device can also drill holes at the bottom of the beam bottom structural column on the ground, it cannot ensure that the electric hammer always moves vertically upward during the process of pushing the electric hammer upward. Therefore, the drill bit is easily broken during the drilling process, and the holes are easily tilted, affecting the normal progress of subsequent rebar embedding. At the same time, the fixing and pushing up of the electric hammer are not stable enough, so it is easy to shake during the drilling process, affecting the normal progress of the drilling.

[0005] 2. When drilling on the ground, a large amount of dust will fall during the drilling process, which will cause interference and harm to the operators. Although some existing rebar drilling devices are equipped with dust collection devices, they cannot always adhere to the bottom surface of the beam bottom structural column during the drilling process, so they cannot effectively prevent dust from falling.

[0006] 3. Since the drilling operation is performed on the ground, the depth of the drilling cannot be directly observed, and the existing rebar embedding drilling device cannot accurately control and adjust the depth of the drilling, thereby reducing the quality of the drilling. Summary of the invention

[0007] The purpose of the present invention is to solve the above-mentioned problems that the electric hammer cannot be guaranteed to move vertically upward all the time, which easily causes the drill bit to break and the hole to be tilted, the dust cannot always be attached to the bottom surface of the bottom structural column of the beam when collected, and it cannot be effectively guaranteed that the dust will not fall, and the fixing and pushing up of the electric hammer are not stable enough, and the depth of the drilling cannot be accurately controlled and adjusted, which reduces the quality of the drilling.

DETAILED DESCRIPTION

[0035] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] A reinforcing bar drilling device for a beam bottom structural column reinforcement according to a preferred embodiment of the present invention will be described in detail below. Figure 1-Figure 3 As shown, a reinforcement drilling device for beam bottom structural column reinforcement includes a box body 1 and a universal wheel 2, the universal wheel 2 is fixedly installed on the bottom end of the box body 1, a lifting component 3 is arranged on the top of the box body 1, and a mounting platform 4 is arranged on the top of the lifting component 3.

[0037] The lifting assembly 3 includes an articulated link 31, and the top of the box body 1 is symmetrically hinged with an articulated link 31. The articulated link 31 is composed of two links hinged to each other, and the top of the articulated link 31 is hinged to the mounting platform 4. Therefore, the mounting platform 4 can be driven to move up and down by folding and stretching the articulated link 31. A connecting column 32 is connected to the hinges of the articulated links 31 on the left and right sides for limited rotation. A central gear 33 is connected to the left and right sides for limited rotation in the center of the right side of the left connecting column 32. A motor 34 is fixedly installed at the center of the left end of the left connecting column 32. The motor 34 is connected to the central gear 33 for transmission. The front and rear sides of the central gear 33 on the right side of the left connecting column 32 are symmetrically connected to the side gears 35 for limited rotation. The front and rear side gears 35 are meshed with the central gear 33. Therefore, during the rotation of the central gear 33, the side gears 35 on both sides can be driven to rotate synchronously.

[0038] A threaded rod 36 is fixedly installed at the center of the right end of the side gear 35. The threaded rod 36 passes through the right connecting column 32 to the right and is threadedly connected to the connecting column 32. The connecting columns 32 on the left and right sides can be telescopically controlled by rotating the threaded rod 36. A hanging ring is fixedly installed at the right end of the threaded rod 36 for manually driving the threaded rod 36 to rotate.

[0039] When drilling is required, the universal wheel 2 at the bottom of the box 1 is used to move the drilling device to the bottom of the structural column at the bottom of the beam. After the position is adjusted, the universal wheel 2 is limited and fixed to ensure that the drilling device is stably parked.

[0040] Then start the motor 34, so that the motor 34 drives the central gear 33 to rotate, and utilizes the mutual engagement of the central gear 33 and the side gear 35 to drive the side gear 35 to rotate, thereby driving the threaded rod 1 36 fixedly installed on the right side of the side gear 35 to rotate synchronously. During the rotation of the threaded rod 1 36, the threaded connection between the threaded rod 1 36 and the right connecting column 32 can drive the connecting columns 32 on the left and right sides to move toward or away from each other, thereby driving the hinged connecting rod 31 to fold downward or stretch upward, so as to adjust the height of the mounting platform 4.

[0041] Furthermore, if Figure 1 , Figure 2 , Figure 4-Figure 7 As shown, a mounting assembly 5 is provided at the top of the mounting platform 4, and the mounting assembly 5 includes a lower connecting rod 51. The lower connecting rods 51 are evenly hinged around the top of the mounting platform 4, and the tops of the lower connecting rods 51 are hinged with cross rods 52. The middle parts of the cross rods 52 are hinged, and a mounting plate 53 is provided on the inner side of the top of the cross rod 52. A covering plate 54 is provided above the mounting plate 53. The central parts of the mounting plate 53 and the covering plate 54 are both hollow in design, so as to realize the installation and dust and falling of the electric hammer 510. The covering plate 54 is provided on the inner side of the top of the cross rod 52. The inner parts of the four sides are all limitedly slidably connected with two symmetrical sliders 55, and a spring 56 is fixedly connected between the two symmetrical sliders 55. An upper connecting rod 57 is hinged between the slider 55 and the top of the cross rod 52, and the hinge between the upper connecting rod 57 and the top of the cross rod 52 is limitedly slidably connected with the outer side of the mounting plate 53, so that the cross rod 52 can be driven to extend or contract during the up and down movement of the mounting plate 53, and the cross rods 52 around the four sides can improve the stability of the up and down movement of the mounting plate 53.

[0042] The mounting assembly 5 also includes a conical cylinder 58, which is fixedly connected to the lower part of the hollow part at the bottom of the center of the mounting plate 53, and can collect falling dust. A fixing seat 59 is fixedly installed on the inner side of the top of the conical cylinder 58, and the fixing seat 59 is hollowed out in the conical cylinder 58 so that dust can pass through the fixing seat 59. An electric hammer 510 is fixed to the inner limit of the fixing seat 59. A threaded rod 511 is fixedly installed in the center of the bottom of the conical cylinder 58, and circular holes 512 are evenly opened on the periphery of the bottom of the conical cylinder 58 so that dust can fall downward through the circular holes 512. A bellows 513 is fixedly connected between the mounting platform 4 and the mounting plate 53, and between the mounting plate 53 and the covering plate 54. The bellows 513 are located on the outer side of the central hollow part of the mounting plate 53 and the covering plate 54 to ensure that dust does not float outward.

[0043] The control power line of the electric hammer 510 is located inside the corrugated tube 513 , and passes downward through the mounting platform 4 to be connected to the box body 1 , so that the electric hammer 510 can be controlled at the box body 1 .

[0044] Conical leakage holes 7 penetrating from top to bottom are provided on the front and rear sides of the internal threaded sleeve 64 of the mounting platform 4. The conical leakage hole 7 is located on the inner side of the bellows 513. A connecting hose 8 is fixedly connected between the bottom of the conical leakage hole 7 and the inside of the box body 1, so that dust entering the inside of the bellows 513 between the mounting platform 4 and the mounting plate 53 can enter the box body 1 through the conical leakage hole 7 and the connecting hose 8, completing collection and cleaning.

[0045] After using the lifting assembly 3 to adjust the height of the mounting platform 4 according to the height of the bottom structural column of the beam from the ground, when drilling, the electric hammer 510 can be started at the box 1 first, and then the pushing assembly 6 can be used to push the mounting plate 53 upward, thereby driving the electric hammer 510 installed in the conical cylinder 58 at the bottom end of the mounting plate 53 to move upward.

[0046] When the cover plate 54 is pushed upward, the upper connecting rod 57 pushes the sliders 55 on each side to compress the springs 56 therebetween and bring them closer to each other. Therefore, after the cover plate 54 contacts the bottom surface of the beam bottom structural column, the mounting plate 53 can drive the electric hammer 510 to continue to move upward, thereby making the drill bit at the top of the electric hammer 510 contact the bottom surface of the beam bottom structural column to drill a hole until the mounting plate 53 and the cover plate 54 can no longer get close to each other, thereby achieving a certain depth of drilling.

[0047] During the process of drilling and operating the drill bit to move up and down repeatedly for drilling, the covering plate 54 can be in contact with the bottom surface of the structural column at the bottom of the beam, thereby preventing dust from floating out. The generated dust will enter the conical cylinder 58 through the bellows 513 between the mounting plate 53 and the covering plate 54, and then enter the bellows 513 between the mounting plate 53 and the mounting platform 4 through the circular hole 512, and then enter the box body 1 through the conical leakage hole 7 and the connecting hose 8 to complete collection and cleaning.

[0048] By adjusting the height of the mounting platform 4, the distance between the mounting platform 4 and the bottom surface of the beam bottom structural column can be adjusted. Due to the difference in the distance, after the covering plate 54 is driven to contact the bottom surface of the beam bottom structural column, the cross rod 52 and the lower connecting rod 51 and the upper connecting rod 57 will extend upward to different extents. Therefore, under the action of the upper connecting rod 57, after the covering plate 54 contacts the bottom surface of the beam bottom structural column, the distance between the mounting plate 53 and the covering plate 54 will also be different. Therefore, when the mounting plate 53 is driven to move upward to complete the drilling, the depth of the drilling will also be different. Then, by adjusting the height of the mounting platform 4, drilling of different depths can be achieved.

[0049] Furthermore, if Figure 1 , Figure 6 , Figure 8-Figure 10 As shown, an upward push assembly 6 is arranged between the bottom of the mounting assembly 5 and the interior of the box body 1, and the upward push assembly 6 includes a bevel gear 1 61, and a bevel gear 1 61 is connected to the center of the top of the box body 1 for limited rotation. The outer side of the bevel gear 1 61 is limited and slidably connected to a cylindrical barrel 1 62, and the inner side of the cylindrical barrel 1 62 is limited and slidably connected to a cylindrical barrel 2 63, and a threaded sleeve 64 is fixedly installed on the top of the cylindrical barrel 2 63, and the threaded sleeve 64 is limited and rotatably connected at the center of the mounting platform 4. The left side of the bevel gear 1 61 at the top of the box body 1 is limited and rotatably connected to a rotating shaft 65, and one end of the rotating shaft 65 close to the bevel gear 1 61 is fixedly installed with a bevel gear 2 66, and the bevel gear 2 66 is meshed with the bevel gear 1 61, so that the rotation of the bevel gear 2 66 can drive the bevel gear 1 61 to rotate, and the end of the rotating shaft 65 away from the bevel gear 2 66 passes through the left inner wall of the box body 1, and a turntable 67 is fixedly installed on it, which is used to drive the rotating shaft 65 and the bevel gear 2 66 to rotate on the left side.

[0050] The second threaded rod 511 passes through the threaded sleeve 64 downward and extends to the interior of the second cylindrical tube 63 , and the second threaded rod 511 is threadedly connected to the threaded sleeve 64 , so when the threaded sleeve 64 rotates, it can drive the second threaded rod 511 to move up and down.

[0051] Among them, the principle of the push-up component 6 pushing the mounting plate 53 to move up and down is: first drive the turntable 67 to rotate, and drive the bevel gear 2 66 to rotate under the action of the rotating shaft 65, and utilize the mutual engagement of the bevel gear 2 66 and the bevel gear 1 61 to drive the bevel gear 1 61 to rotate. During the rotation of the bevel gear 1 61, the limited sliding connection between the bevel gear 1 61 and the cylindrical barrel 1 62, and the limited sliding connection between the cylindrical barrel 1 62 and the cylindrical barrel 2 63 can drive the cylindrical barrel 1 62 and the cylindrical barrel 2 63 to rotate, and then drive the threaded sleeve 64 at the top of the cylindrical barrel 2 63 to rotate. During the rotation of the threaded sleeve 64, the threaded connection between the threaded sleeve 64 and the threaded rod 2 511 can drive the threaded rod 2 511 to move up and down, and then drive the conical barrel 58 and the mounting plate 53 to move up and down.

[0052] At the same time, by utilizing the limited sliding connection between bevel gear 1 61 and cylindrical barrel 1 62, and the limited sliding connection between cylindrical barrel 1 62 and cylindrical barrel 2 63, when the mounting platform 4 is adjusted up and down to drive the threaded sleeve 64 to move up and down, the rotation of bevel gear 1 61 can drive the threaded sleeve 64 to rotate.

[0053] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
