DETAILED DESCRIPTION

[0038] 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.

[0039] Example: Reference Figure 1-9The illustrated embodiment of a construction engineering hanger installer comprises a rod body 3 with an electric drill 4 mounted on its upper end, a drilling unit 5 or a hanger installation unit 6 detachably mounted on the self-locking head of the electric drill 4, and a lifting unit for lifting the rod body 3, wherein the lifting unit comprises a first adjustment unit 7 and a second adjustment unit 8, wherein the first adjustment unit 7 is used to lift and lower the entire installer, and the second adjustment unit 8 is used to lift and lower the rod body 3, and the first adjustment unit 7 and the second adjustment unit 8 are performed synchronously. When installing the hanger, the drilling unit 5 can be first mounted on the electric drill 4. When the installer is pushed to the drilling position, the lifting unit can be controlled to lift the rod body 3, and the electric drill 4 can drive the drilling unit to drill holes on the indoor ceiling for the subsequent installation of the suspension rod. After all the installation holes are drilled, the drilling unit 5 is removed and replaced with the suspension rod installation unit 6. After the suspension rod is installed on the suspension rod installation unit 6, the lifting unit is used to push the upper end of the expansion bolt on the suspension rod into the installation hole, and then the electric drill 4 is used to drive the suspension rod installation unit 6 to rotate so that the expansion ring of the expansion bolt opens and is in close contact with the inner wall of the installation hole to form a fixation. At this point, the suspension rod is installed.

[0040] As a preferred implementation in this embodiment, Figure 1-9As shown, the second adjustment unit 8 includes two mounting frames 82 respectively fixed on two mounting plates 1 arranged in an upper and lower manner, a hollow column 81 is rotatably arranged between the two mounting frames 82, a moving round block 86 is threadedly connected in the cylindrical threaded cavity of the hollow column 81, the upper end of the moving round block 86 is fixedly connected to the lower end of the rod body 3 located in the inner cavity of the hollow column 81, the upper end of the rod body 3 passes through the upper mounting plate 1, a first driven gear 83 is fixed on the outer wall of the hollow column 81, and the first driven gear 83 is connected to the output of the driving motor 84. The drive gear 85 mounted on the output shaft is meshed and connected, and the drive motor 84 is fixedly mounted on the lower mounting plate 1. The first adjustment unit 7 includes a plurality of columns 71 with rectangular through cavities fixedly arranged between the two mounting plates 1 and arranged in a circumferential manner. A ring 77 is arranged between the plurality of columns 71, and a threaded tube 78 sleeved on the screw 75 is installed on the ring 77. The screw 75 is rotatably arranged between the two mounting plates 1, and a second driven gear meshed and connected with the first driven gear 83 is fixedly arranged on the screw 75. 76, a connecting block 72 corresponding to a plurality of columns 71 is fixed in a circumferential manner on the outer wall of the ring 77, the connecting block 72 is extended in the corresponding rectangular through cavity and fixedly connected to the support rod 73, and the lower end of the support rod 73 passes through the column 71 and is connected to the caster 74. When the driving motor 84 is controlled to work, the driving motor 84 drives the hollow column 81 to rotate through the gear, and the rotation of the hollow column 81 will cause the moving block 86 to drive the rod body 3 to move upward. At the same time, the hollow column 81 drives the screw 75 to rotate through the gear, and the ring 77 moves downward under the action of the threaded tube 78, and then the whole installer is lifted by the support rod 73. Through the cooperation of the first adjusting unit 7 and the second adjusting unit 8, the height of the rod body 3 can be quickly adjusted, thereby improving the working efficiency. In addition, since the device adopts a double adjustment mechanism, the height adjustment range of the rod body 3 is greatly extended, so that the device can also adapt to the long-distance punching operation under the condition of small volume (its occupied space is also relatively reduced);

[0041] The drilling unit 5 comprises a first cylinder 51 with an opening at the upper end and a sealed bottom, and a second cylinder 52 with a through hole in the inner cavity and slidably sleeved on the outer periphery of the first cylinder 51. An air inlet hole is arranged on the outer wall of the second cylinder 52 near the upper end. The first cylinder 51 and the second cylinder 52 are connected by a telescopic spring 53. A limit rod 56 is fixed to the lower end of the first cylinder 51, and the lower end of the limit rod 56 is plugged into the upper end of the rod body 3. A drill rod 57 is rotatably arranged in the inner cavity of the first cylinder 51, and the lower end of the drill rod 57 is mounted on the self-locking head of the electric drill 4. The upper end of the drill rod 57 penetrates the set A dust hood 55 is provided in the inner cavity of the first cylinder 51, and the dust outlet of the dust hood 55 passes through the bottom of the first cylinder 51. A plurality of blades 54 are arranged in a circle on the drill rod 57. The upper end of the drill rod 57 is flush with the upper end surface of the second cylinder 52. The drilling unit 5 is installed on the electric drill 4 through the self-locking head, and the installer is moved to the drilling point through the casters 74. At this time, the driving motor 84 is controlled to work and the electric drill 4 is operated. The height of the rod body 3 is adjusted by the cooperation of the first adjusting unit 7 and the second adjusting unit 8. When the upper end of the second cylinder 52 contacts the indoor top wall, the height of the rod body 3 is adjusted. After that, the drill rod 57 will contact the indoor top wall and perform the drilling operation. As the drill rod 57 continues to rise, the second cylinder 52 will compress the telescopic spring 53, so that during the entire drilling process, the second cylinder 52 always maintains good contact with the indoor top wall, ensuring that the dust generated during drilling does not overflow the space surrounded by the first cylinder 51 and the second cylinder 52. At the same time, when the drill rod 57 performs high-speed rotation drilling, it can drive the blade 54 to rotate. The rotating blade 54 can form a negative pressure on the upper end of the dust collecting cover 55, and the outside air can enter the first cylinder 5 through the air inlet. 1 and flows downward, and the dust generated is driven downward by the downwardly flowing airflow, and enters the filter bag threadedly installed on the discharge port of the dust collecting cover 55 through the guide of the dust collecting cover 55 (the filter bag has air permeability, which allows the inhaled gas to return to the outside to form a cycle, which is conducive to the accumulation of dust in the filter bag) for dust collection, which can effectively prevent the diffusion of dust. After reaching the drilling depth requirement, the driving motor 84 is controlled to rotate in the reverse direction to move the electric drill 4 out of the drilled installation hole, and then the installer is moved to the next location for drilling;

[0042] The sling installation unit 6 includes a first C-shaped column 61 with a mounting head 65 at the bottom, a second C-shaped column 62 is arranged at the upper end of the first C-shaped column 61, and a limiting groove 63 adapted to the nut is opened on the second C-shaped column 62, a bottom plate 64 is fixed to the bottom of the first C-shaped column 61, and a top plate 67 is arranged above the bottom plate 64, and a telescopic rod 66 is fixed between the top plate 67 and the bottom plate 64, and a fastening spring 68 is fixedly installed on the periphery of the telescopic rod 66, and a cylinder 69 with a plug-in groove is rotatably arranged at the upper end of the top plate 67, and the axis of the limiting groove 63 and the cylinder 69 are on the same straight line. During the whole process of the sling installation, the lower end of the nut on it is always not in contact with the bottom of the inner cavity of the limiting groove 63. After the installation hole is drilled, the drilling unit 5 can be removed from The self-locking head of the electric drill 4 is removed and the mounting head 65 of the hanging rod mounting unit 6 is mounted on the self-locking head, and the lower end of the nut on the hanging rod is inserted into the limiting groove 63 (the lower end of the nut is one end away from the bottom of the limiting groove 63, and the upper end of the nut is located above the limiting groove 63). At the same time, the lower end of the hanging rod is inserted into the plug-in slot of the cylinder 69 and contacts the inner bottom of the plug-in slot. After the hanging rod is placed, the first adjustment unit 7 and the second adjustment unit 8 are used to drive the upper end of the expansion bolt on the hanging rod to be inserted into the mounting hole. When the upper end of the expansion bolt contacts the mounting hole and forms an extrusion conflict, it will drive the hanging rod to move downward and squeeze the tightening spring 68 (which has a buffering effect on the cylinder 69 to prevent it from being subjected to excessive extrusion force ) moves a short distance and then stops the movement of the first adjusting unit 7 and the second adjusting unit 8 (at this time, the lower end of the nut is not in contact with the bottom of the limiting groove 63, and the upper end of the nut is located above the limiting groove 63). At this time, the upper and lower ends of the hanging bar are clamped and fixed by the inner wall of the mounting hole and the cylinder 69 respectively, and the main body of the hanging bar remains stable. The electric drill 4 is controlled to drive the hanging bar mounting unit 6 to rotate at a low speed. During this rotation process, the rotating second C-shaped column 62 drives the nut in the limiting groove 63 to rotate. At this time, the nut makes a rotational upward movement in the limiting groove 63. The upward movement of the nut will squeeze the expansion ring on the hanging bar to move upward and open at the same time, so that the outer wall of the expansion ring is squeezed and squeezed with the inner wall of the mounting hole, thereby firmly fixing the hanging bar and the mounting hole. After the two ends of the nut are fixed together, the rotation of the electric drill 4 is stopped (at this time, the lower end of the nut has not completely disengaged from the limiting groove 63). After the installation of the hanging bar is completed, the control rod body 3 moves downward while pushing the installer to move. After the nut moves out of the limiting groove 63 and the lower end of the hanging bar moves out of the cylinder 69, the part of the hanging bar located at the first C-shaped column 61 and the second C-shaped column 62 can be moved out from the opening of the first C-shaped column 61 and the second C-shaped column 62. At this time, the hanging bar is completely separated from the hanging bar installer, and the upper and lower ends of the hanging bar are clamped and fixed by the inner wall of the installation hole and the rotatable cylinder 69 to keep the main body of the hanging bar stable. At the same time, when the hanging bar is installed, the lower end of the nut is always kept from contacting the inner bottom of the limiting groove 63 (the advantage of not contacting is that the lower end of the nut is not subjected to the extrusion force,This prevents the friction F1 between the nut and the threaded section on the hanging rod from increasing due to the extrusion force on the lower end of the nut. When F1 is greater than the friction F2 that prevents the hanging rod from rotating, the nut is likely to drive the hanging rod body to rotate together when the electric drill 4 is driven at a low speed, thereby affecting the installation of the hanging rod). Then, the electric drill 4 uses the rotating second C-shaped column 62 to drive the nut to rotate upward on the hanging rod, which can ensure that the hanging rod body does not rotate with the rotation of the nut when the hanging rod is installed, avoiding affecting the installation of the hanging rod.

[0043] It should be noted that, first, the rod body can be set to a rectangular, square or other shaped structure. In this embodiment, the rod body 3 adopts a square structure, and its upper end passes through the upper mounting plate 1. The rod body 3 can only move up and down through the limit of the mounting plate 1; second, the drive motor 84 and the electric drill 4 are electrically connected to the programmable PLC controller provided on the upper end of the upper mounting plate 1, and each of its electrical equipment is electrically connected to the power supply provided inside the lower mounting plate 1. The number of revolutions of the drive motor 84 when drilling can be set through the PLC controller, that is, the height of the rod body 3 is controlled, thereby controlling the drilling The hole depth is set to set the number of revolutions of the driving motor 84 when the hanging rod is installed, that is, to control the height of the rod body 3, and then control the depth of the upper end of the hanging rod inserted into the installation hole and the compression amount of the tightening spring 68; Third, the drilling unit 5 and the hanging rod installation unit 6 on the installer are installed together with the rod body through the self-locking head on the electric drill 4, which is convenient for the removal and installation of the drilling unit 5 and the hanging rod installation unit 6; Fourth, the inner wall of the limiting groove 63 is set to a smooth surface, which can reduce the resistance of the nut when it moves upward; Fifth, the lower end of the cylinder 69 is fixed to the top plate 67 through a bearing, and the bearing is fixed The cylinder 69 is fixed at the upper end of the top plate 67, and the lower outer wall of the cylinder 69 is fixedly connected to the inner ring wall of the bearing, and the lower end of the cylinder 69 does not contact the top plate 67. This design structure is conducive to the resistance-free rotation of the cylinder 69. When the cylinder 69 rotates, the resistance is too large, which is not conducive to the stability of the main body of the hanging bar in the clamped fixed state, and may even drive the main body of the hanging bar to rotate with the first C-shaped column 61, which is not conducive to the installation of the hanging bar; Sixth, the first C-shaped column 61 can be set to be telescopic, and its own length can be changed to adapt to the installation and adjustment of hanging bars of different lengths; Seventh, for this The installer can remove the rod body 3 with the electric drill from the installer for use (at this time, the electric drill is electrically connected to an external power supply). At this time, the first cylinder 51 and the second cylinder 52 are both set to a transparent color (to facilitate personnel to observe the drilling position). The operator holds the rod body 3 and cooperates with the drilling unit 5 and the suspension rod installation unit 6 to perform drilling and suspension rod installation operations. However, this operation method requires that the rod body 3 be held all the time and the upper and lower ends of the suspension rod need to be in contact with the inner wall of the installation hole and the cylinder body, which makes the suspension rod installation operation labor-intensive and is not conducive to the stability of the drilling, and it is easy to drill the hole off-center.

[0044] As a preferred implementation in this embodiment, Fig. 9 As shown, the upper end of the mounting head 65 is rotatably connected to the lower end of the base plate 64 through a rotating rod 610, and a tightening elastic sleeve 611 is sleeved on the outer periphery of the rotating rod 610, and the upper and lower end surfaces of the tightening elastic sleeve 611 respectively contact the bottom of the base plate 64 and the top of the mounting head 65. When the electric drill 4 is used to install the hanging rod and the hanging rod is fixed to the mounting hole, in order to prevent the continued rotation of the electric drill 4 from causing excessive extrusion and deformation of the expansion ring, which is not conducive to the subsequent removal of the hanging rod from the mounting hole, the mounting head 65 is rotatably connected to the base plate 64 through the rotating rod 610, and a tightening elastic sleeve 611 is sleeved on the rotating rod 610. When the hanging rod is installed, the electric drill 4 is used to drive the mounting head 63 to rotate, and the tightening elastic sleeve is used to tighten the mounting head 63. The friction between 611 and the base plate 64 and the mounting head 65 drives the first C-shaped column 61 and the second C-shaped column 62 to rotate, and then drives the nut to rotate, the outer wall of the expansion ring opens and is squeezed with the inner wall of the mounting hole. When the outer wall of the expansion ring is in tight squeeze contact with the inner wall of the mounting hole (at this time the suspension rod is firmly fixed on the indoor ceiling and the installation requirements are met), the first C-shaped column 61 and the second C-shaped column 62 will remain stationary, and the mounting head 65 will rotate relative to the first C-shaped column 61 and the second C-shaped column 62, thereby preventing the expansion ring from being excessively squeezed and deformed, which is beneficial for removing the suspension rod from the mounting hole during subsequent indoor redecoration, and is also beneficial for the secondary use of the removed suspension rod.

[0045] It should be noted that the lower end of the fastening elastic sleeve 611 is fixed to the upper end of the mounting head 65 or the upper end of the fastening elastic sleeve 611 is fixed to the lower end of the bottom plate 64 .

[0046] As a preferred implementation in this embodiment, Figure 2As shown, the lower ends of several support rods 73 are fixedly connected to the fixing ring 10, a cross bar 11 is fixed in the annular cavity of the fixing ring 10, and a vertically arranged indicating rod 9 is fixed to the lower end of the cross bar 11, the axis of the indicating rod 9 is respectively on the same straight line as the axis of the drill rod 57 or the limiting groove 63 installed on the electric drill 4, and the mounting plate 1 located below is set to a C-shaped structure. Before drilling, it is necessary to mark the position of the drilling point, and the drilling point position can be marked on the indoor floor (compared with drawing lines on the indoor ceiling wall and marking points by using climbing tools, drawing lines on the ground is convenient and quick, and does not require climbing tools, and is safer). Move the installer, and when the lower part of the indicating rod 9 is When the end is in the same vertical direction as the position mark, the drilling unit 5 is lifted by the first adjusting unit 7 and the second adjusting unit 8, and the point where the drill rod 57 contacts the indoor ceiling is the drilling point corresponding to the ground position mark. Similarly, when installing the suspension rod, when the lower end of the indicator rod 9 is consistent with the position mark, the upper end of the suspension rod can be directly inserted into the mounting hole through the lifting unit, which is convenient for locating the mounting hole. The C-shaped structure of the lower mounting plate 1 is provided to facilitate personnel to observe whether the indicator rod 9 is consistent with the position mark through this opening. At the same time, the setting of the fixing ring 10 can connect several support rods 73 into a whole and enhance the structural strength of the support rod 73.

[0047] As a preferred implementation in this embodiment, Figure 1 and Fig.10 As shown, it also includes a push rod unit 2 for pushing the entire installer to move. The push rod unit 2 includes two push rods 21 fixedly arranged on the fixing ring 10, and the two push rods 21 are connected by a connecting rod 22. A limit slider 23 is fixedly arranged on the two push rods 21, and the outer ends of the two limit sliders 23 are slidably arranged in a slide groove provided on the outer wall of the corresponding column 71. The two push rods 21 are both arranged close to the opening of the lower mounting plate 1, and the installer can be pushed to move by the push rod 21. The push rod 21 is arranged at the opening, so that when the personnel push the installer to move, they have a sufficiently open field of vision to observe whether the lower end of the indicator rod 9 is consistent with the drilling point position mark. The setting of the limit slider 23 and the connecting rod is to ensure that the push rod 21 cannot be deformed left and right, front and back under external force, thereby improving the structural strength of the two push rods 21. At the same time, the sliding setting of the limit slider 23 and the column 71 ensures that when the column 71 is raised, the height of the push rod unit 2 remains unchanged, which is convenient for personnel to hold.

[0048] It should be noted that, in order to conveniently control the working states of the electric drill 4 and the drive motor 84 , control keys for controlling the electric drill 4 and the drive motor 84 may be disposed on the hand grip of the push rod 21 .

[0049] As a preferred implementation in this embodiment, Figure 1As shown, a protective plate 12 is provided between two adjacent columns 71 for protecting the second driven gear 83 and the driving gear 85. The protective plate 12 is intended to prevent the working gears from contacting other objects when the installer is pushed to move, causing the gears to malfunction or be damaged.

[0050] It should be noted that a protective plate 12 is provided between the two upright posts 71 near the C-shaped opening of the lower mounting plate 1 to protect the first driven gear 83 . At the same time, in order to facilitate the operator to observe the indicator rod 9 , the protective plate 12 is set to be transparent.

[0051] As a preferred implementation mode in this embodiment, not shown in the figure, the outer surface of the fastening elastic sleeve 611 is provided with a layer of ZS-711 inorganic anti-corrosion coating which can extend its service life. The ZS-711 inorganic anti-corrosion coating has excellent corrosion resistance and wear resistance, which can greatly improve the service life of the fastening elastic sleeve 611.

[0052] As a preferred implementation in this embodiment, Figure 1 As shown, a self-locking part is installed at the upper end of the upper mounting plate 1, and the self-locking part is used to fix the drilling unit 5 or the hanging rod mounting unit 6. When the drilling unit 5 or the hanging rod mounting unit 6 is not in use, the drilling unit 5 or the hanging rod mounting unit 6 can be fixed together with the self-locking part, which can avoid temporarily placing the drilling unit 5 or the hanging rod mounting unit 6 at other placement points. It takes a certain amount of time to go back and forth from the temporary placement point to get the drilling unit 5 or the hanging rod mounting unit 6, which is not conducive to improving the work efficiency of the hanging rod installation.

[0053] It should be noted that in this embodiment, a self-locking part with the same structure as the self-locking head on the electric drill 4 is selected, and the drill rod 57 of the drilling unit 5 or the mounting head 65 of the hanger mounting unit 6 can be fixed together with the self-locking part, and self-locking parts of other structures can also be used.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
