Description

Technical Field

[0001] This invention relates to the field of building decoration technology, and in particular to a ceiling suspension rod installation tool and its installation method. Background Technology

[0002] During the installation of ceiling hangers, expansion bolts are typically fixed into the expansion threaded holes in the ceiling, and then the hanger is connected to the expansion bolts to complete the installation. However, in practice, due to the high ceiling height, installers often try to align the expansion bolts with the expansion threaded holes by connecting the expansion bolts to a long-handled wrench. This process is difficult due to the height of the ceiling, wasting time and increasing the workload for the installers. Furthermore, when inserting the expansion bolts into the expansion threaded holes, space constraints and operational difficulties often prevent installers from applying sufficient force, causing the bolts to fail to insert smoothly and further complicating the installation process.

[0003] Therefore, it is necessary to develop a tool that can help installers quickly and accurately align expansion bolts with expansion threaded holes and facilitate the insertion of expansion bolts, so as to improve installation efficiency and accuracy. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of existing methods, such as difficulty in aligning expansion bolts with expansion threaded holes and the need for considerable force when inserting expansion bolts into expansion threaded holes, and to propose a ceiling hanger installation tool and its installation method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ceiling hanger installation tool, comprising:

[0007] Control cylinder;

[0008] A connecting plate is positioned above the control cylinder;

The adjustment structure includes a connecting cylinder that is fixed through the connecting plate, and the bottom end of the connecting cylinder extends into the control cylinder.

[0012] A drive structure, including rollers, is used to move the connecting plate along the ceiling;

[0013] A striking structure, including a striking post, for inserting an expansion bolt into an expansion threaded hole;

[0014] The roller is driven to rotate in one direction by a drive structure, so that the adjusting sleeve moves and aligns with the expansion threaded hole.

[0015] In one possible design, the adjustment structure further includes a positioning bolt threaded through the operating cylinder, and a plurality of positioning grooves are provided on one side of the connecting cylinder, with the positioning bolts engaging with the positioning grooves; it also includes a rotating structure, which includes a rotating handle rotating at the bottom of the operating cylinder, a rotating cylinder fixed to the top of the rotating handle, the top of the rotating cylinder extending rotatably into the operating cylinder and slidingly into the connecting cylinder, the rotating cylinder being slidably connected to a sliding rod via a groove and a slider, and the top of the sliding rod being fixedly connected to the bottom of gear I.

[0016] In one possible design, the bottom of the adjusting sleeve is fixed with a retaining ring that penetrates the connecting plate. The adjusting sleeve passes through gear II and slides with gear II through a groove and a slider. The adjusting sleeve has a hexagonal groove inside, which engages with the expansion bolt. The rotating handle drives gear I to rotate through the rotating cylinder and the sliding rod. Gear I drives gear II to rotate. Gear II drives the expansion bolt to rotate through the adjusting sleeve.

[0017] In one possible design, the drive structure further includes a fixed cylinder, which is fixedly connected to the top of the connecting plate via multiple L-shaped rods.

A fixed cylinder is fixed to one side of the U-shaped seat, and a piston rod is slidably connected and sealed inside the fixed cylinder. A rack is fixed to the top of the piston rod, and the rack meshes with gear III. The reciprocating movement of the rack drives gear III to reciprocate, and the one-way bearing drives the roller to rotate unidirectionally.

[0018] In one possible design, the drive structure further includes a hollow tube rotatably mounted on one side of the control cylinder. A connecting hose is fixed to the outer wall of the hollow tube, and the top end of the connecting hose is fixedly connected to the bottom of the fixed cylinder. A disc spring is fitted onto the outer wall of the hollow tube, and the two ends of the disc spring are fixedly connected to the outer wall of the hollow tube and one side of the control cylinder, respectively, via connecting seats. A hollow disc is rotatably and sealed to one end of the hollow tube, and a piston plate is slidably and sealed inside the hollow disc. A nut seat is fixed to the side of the piston plate away from the hollow tube via a support rod. A reciprocating screw is rotatably connected to the side of the hollow disc away from the hollow tube. The reciprocating screw passes through the nut seat, and a sliding block is fixed inside the nut seat, which slides in cooperation with the spiral groove on the outer wall of the reciprocating screw. The reciprocating screw is manually rotated to drive the piston plate to move back and forth, and the flow of hydraulic oil inside the fixed cylinder is controlled by the connecting hose.

[0019] In one possible design, a No. III spring abuts against the bottom of the sliding seat and the inner wall of the bottom of the fixed cylinder. A fixed plate is provided on one side of the fixed cylinder, and a limit rod is fixed on one side of the fixed plate. The limit rod slides into the fixed cylinder. A tension spring is sleeved on the outer wall of the fixed cylinder. The two ends of the tension spring are fixedly connected to the outer wall of the fixed cylinder and one side of the fixed plate respectively through spring seats. Multiple No. I magnets are fixed on one side of the fixed cylinder, and multiple electromagnets are fixed on one side of the fixed plate. The limit rod limits the sliding seat, and the repulsive force between the electromagnets and the No. I magnets drives the limit rod to move.

[0020] In one possible design, the striking structure further includes a pull rod fixed to the bottom end of the striking column, the bottom end of the pull rod extending slidably to the bottom of the rotating handle, the bottom of the striking column and the inner wall of the bottom of the rotating handle being in contact by a No. I spring, the striking column sliding within the rotating handle; wherein, by pulling and releasing the striking column with the pull rod, the operating cylinder is struck under the elastic force of the No. I spring, causing the expansion bolt to be inserted into the expansion threaded hole.

[0021] In one possible design, a light is fixed to the side of the fixed cylinder near the adjusting sleeve, and a light strip is fixed to the side of the U-shaped seat near the adjusting sleeve; wherein the light and the light strip provide illumination to determine alignment.

[0022] In one possible design, the outer wall of the fixed ring is provided with an annular groove, the bottom of the connecting plate is fixed with a base, a slide rod slides through the base, one end of the slide rod is fixed with a trapezoidal block, and the outer wall of the slide rod is fitted with a No. II spring. The two ends of the No. II spring are fixedly connected to the base and the trapezoidal block respectively through spring seats; wherein, the trapezoidal block cooperates with the annular groove to limit the position of the fixed ring.

[0023] This application discloses a method for installing a ceiling hanger tool, comprising the following steps:

[0024] S1. Component connection: Connect the expansion bolt to the hanger rod; install the adjusting sleeve to the connecting plate, specifically: make the fixing ring pass through the connecting plate, and under the action of the spring, the trapezoidal block is inserted into the circular groove of the connecting plate to achieve the limit; pass one end of the hanger rod through the hexagonal groove and through hole of the adjusting sleeve in sequence, and make one end of the expansion bolt engage with the hexagonal groove.

[0025] S2. Height Adjustment: Loosen the positioning bolt to disengage it from the positioning groove of the control cylinder; pull out the connecting cylinder inside the control cylinder to the required length according to the ceiling height; tighten the positioning bolt to lock it into the corresponding positioning groove to achieve the positioning of the connecting cylinder.

[0026] S3. Lifting and Positioning: Vertically lift the operating cylinder and connecting cylinder so that the rollers abut against the ceiling; rotate the connecting cylinder to adjust the relative position of the expansion bolt inside the adjusting sleeve and the bolt hole on the ceiling to be in a straight line.

[0027] S4. Fine-tuning Alignment: Manually rotate the reciprocating screw; the reciprocating screw drives the nut seat and piston plate to move back and forth within the fixed cylinder; the piston plate draws or injects hydraulic oil through the connecting hose, driving the rack to move back and forth; the rack drives gear III to rotate back and forth; gear III drives the rotating column and roller to rotate unidirectionally through the one-way bearing, causing the adjusting sleeve and expansion bolt to gradually move toward the ceiling bolt hole until precise alignment; at the same time, lighting lamps and light strips are used to provide illumination to assist in judging the alignment status.

[0028] S5. Insertion preparation: Control the electromagnet to be energized by the button on the side of the control cylinder; the magnetic force between the electromagnet and the magnet drives the limit rod to move outward, releasing the brake on the sliding seat.

[0029] S6, Impact Embedding: Push the operating cylinder, connecting cylinder and connecting plate upward to push the expansion bolt into the bolt hole of the ceiling, while the U-shaped seat and roller are stored in the fixed cylinder; pull the pull rod downward to move the striking column down and release it, and use the spring force to make the striking column repeatedly strike the operating cylinder to impact and embed the expansion bolt into the bolt hole to the predetermined depth.

[0030] S7. Tightening Installation: Rotating the handle drives the rotating cylinder to rotate; the rotating cylinder drives gear I to rotate via the sliding rod; gear I drives gear II to rotate; gear II drives the adjusting sleeve and its internal expansion bolts to rotate, completing the tightening installation of the expansion bolts in the ceiling bolt holes, thereby fixing the hanger.

[0031] S8. Device storage: Push the connecting cylinder back into the operating cylinder; the coil spring drives the hollow tube to rotate, automatically winding up the connecting hose.

[0032] Beneficial effects: In this invention, a rotating column is rotatably connected inside the U-shaped seat, and a roller is fixedly sleeved on the outer wall of the rotating column. A one-way bearing is sleeved on the outer wall of the rotating column, and a No. III gear is fixed on the outer ring of the one-way bearing. The cooperation between the one-way bearing and the rotating column is used to drive the roller to rotate in one direction. A fixed cylinder is fixed on one side of the U-shaped seat, and a piston rod is slidably connected inside the fixed cylinder. A rack is fixed at the top of the piston rod. The rack can drive the No. III gear to rotate back and forth by moving up and down. The No. III gear can drive the rotating column and the roller to rotate in one direction by cooperating with the rotating column and the one-way bearing. This can drive the adjusting sleeve to gradually move towards the expansion threaded hole until the expansion bolt inside the adjusting sleeve is aligned with the expansion threaded hole, which facilitates the subsequent installation of the expansion bolt in the expansion threaded hole.

[0033] In this invention, a connecting hose is fixed to the outer wall of the hollow tube, and the top end of the connecting hose is fixedly connected to the bottom of the fixed cylinder. A hollow disc is rotatably and sealed to one end of the hollow tube, and a piston plate is slidably and sealed inside the hollow disc. A nut seat is fixed to one side of the piston plate, and a reciprocating screw is rotatably connected to the side of the hollow disc away from the hollow tube. A sliding block is fixed inside the nut seat, which slides in cooperation with the spiral groove on the outer wall of the reciprocating screw. The reciprocating screw drives the piston plate to move back and forth linearly through the nut seat. The piston plate, through the cooperation of the connecting hose, completes the extraction or injection of hydraulic oil in the fixed cylinder, thereby controlling the reciprocating up and down movement of the rack, and driving the roller to rotate, which facilitates the operator to position the expansion bolt and the expansion thread hole.

[0034] In this invention, a pull rod is fixed to the bottom end of the striking column, and the bottom end of the pull rod slides to the bottom of the rotating handle. The bottom of the striking column and the inner wall of the bottom of the rotating handle are in contact by a No. I spring. The striking column is pulled down by the pull rod, and then the pull rod is released. Under the elastic force of the No. I spring, the striking column strikes the operating cylinder. The reciprocating operation can easily insert the expansion bolt into the expansion thread hole, which is convenient for the expansion bolt to be screwed into the expansion thread hole later.

[0035] In this invention, the outer wall of the fixing ring is provided with a circular groove, the bottom of the connecting plate is fixed with a base, a sliding rod slides through the base, and a trapezoidal block is fixed to one end of the sliding rod; the fixing ring passes through the connecting plate, and the trapezoidal block extends into the circular groove under the action of spring II, and the right-angled side of the trapezoidal block cooperates with the circular groove to limit the fixing ring, so as to easily complete the installation of the connecting plate and the fixing ring. In addition, it is convenient to replace the adjusting sleeve of the corresponding size later as needed.

[0036] In this invention, the driving structure, striking structure, and rotating structure achieve beneficial effects such as improving installation efficiency, ensuring installation quality, enhancing safety, strong versatility, and ease of operation. This installation tool can effectively solve the problems of low installation efficiency, significant safety hazards, and unstable installation quality in the prior art, providing an efficient, safe, and reliable solution for ceiling installation.

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0051] In one embodiment: Refer to Figures 1-3 The installation tools relate to the field of construction equipment technology, including a control cylinder 1, a connecting plate 7, an adjusting sleeve 14, an adjusting structure, a driving structure, and a striking structure.

[0052] Reference Figure 1 , Figure 2 and Figure 5 The control cylinder 1 is the main operating component for installing the tool, facilitating handheld operation by the worker. A connecting plate 7 is located above the control cylinder 1, and gears 13 (II) and 8 (I) are rotatably connected to the top of the connecting plate 7, with gear 8 meshing with gear 13 (II). This gear transmission structure enables efficient power transmission and speed regulation.

[0053] Reference Figure 4 and Figure 5Multiple adjusting sleeves 14 are inserted into the connecting plate 7, and adjusting sleeves 14 of different sizes can be used with expansion bolts of different sizes. A fixing ring 16 is fixed to the bottom of the adjusting sleeve 14, penetrating the connecting plate 7. The adjusting sleeve 14 passes through gear II 13 and slides with gear II 13 via a groove and a slider. The adjusting sleeve 14 has a hexagonal groove 15 inside, which mates with the expansion bolt. Both the adjusting sleeve 14 and the fixing ring 16 have through holes 46, and the hexagonal groove 15 communicates with adjacent through holes 46 for inserting the lifting rod. This design allows the adjusting sleeves 14 to be easily replaced to accommodate expansion bolts of different sizes, improving the versatility of the installation tools.

[0054] Reference Figures 1-3 An adjustment structure is located between the operating cylinder 1 and the connecting plate 7 to adjust the distance between them, so that the expansion bolt inside the adjusting sleeve 14 can mate with the expansion threaded hole on the ceiling. The adjustment structure includes a connecting cylinder 2 fixed through the connecting plate 7, with the bottom end of the connecting cylinder 2 extending into the operating cylinder 1. The adjustment structure also includes a positioning bolt 4 threaded through the operating cylinder 1. Multiple positioning grooves 3 are provided on one side of the connecting cylinder 2, and the positioning bolt 4 engages with the positioning grooves 3 to position the connecting cylinder 2 and control its extension length.

[0055] In practice, workers can loosen the positioning bolt 4 according to the ceiling height, causing one end of the positioning bolt 4 to disengage from the positioning groove 3, pulling the connecting cylinder 2 out of the operating cylinder 1, adjusting the extension length of the connecting cylinder 2, and completing the positioning of the connecting cylinder 2 through the cooperation of the positioning bolt 4 and the positioning groove 3. This adjustment structure is simple and reliable, and can easily adjust the distance between the operating cylinder 1 and the connecting plate 7 to adapt to ceilings of different heights.

[0056] Reference Figure 2 , Figure 3 and Figure 6 In order to enable the expansion bolt to be screwed into the expansion thread hole, a rotating structure is provided in the operating cylinder 1. The rotating structure includes a rotating handle 9 rotating at the bottom of the operating cylinder 1, a rotating cylinder 5 fixed at the top of the rotating handle 9, the top of the rotating cylinder 5 extending into the operating cylinder 1, and the top of the rotating cylinder 5 slidingly extending into the connecting cylinder 2. A sliding rod 6 is slidably connected to the rotating cylinder 5 through a sliding groove and a slider. The top of the sliding rod 6 is fixedly connected to the bottom of the No. I gear 8. The rotating cylinder 5 drives the No. I gear 8 to rotate through the sliding rod 6. A fixing ring 16 penetrating the connecting plate 7 is fixed at the bottom of the adjusting sleeve 14. The adjusting sleeve 14 penetrates the No. II gear 13 and slides with the No. II gear 13 through a sliding groove and a slider. A hexagonal groove 15 is provided in the adjusting sleeve 14. The hexagonal groove 15 cooperates with the expansion bolt. Both the adjusting sleeve 14 and the fixing ring 16 are provided with through holes 46. The hexagonal groove 15 is connected to the adjacent through hole 46 for the insertion of the boom.

[0057] Specifically, the rotating handle 9 drives the rotating cylinder 5 to rotate, and the rotating cylinder 5 drives the No. I gear 8 to rotate via the sliding rod 6. The radius of the No. I gear 8 is larger than the radius of the No. II gear 13. The No. I gear 8 can easily drive the No. II gear 13 to rotate. The No. II gear 13 drives the expansion bolt inside it to rotate via the adjusting sleeve 14, thereby completing the installation of the expansion bolt and the expansion thread hole, and thus completing the installation of the hanging rod and the ceiling.

[0058] Reference Figures 5-10 To enable the connecting plate 7 to move smoothly along the ceiling and align the adjusting sleeve 14 with the expansion threaded hole, a drive structure is provided on the top of the connecting plate 7. The drive structure includes components such as rollers 33, fixed cylinders 22, sliding seats 23, U-shaped seats 30, rotating columns 32, one-way bearings 34, gear III 35, fixed cylinders 36, piston rods 37, racks 38, hollow tubes 40, connecting hoses 39, disc springs 41, hollow discs 42, piston plates 43, nut seats 44, and reciprocating lead screws 45, all mounted on the connecting plate 7.

[0059] Reference Figure 5 , Figure 6 , Figure 8 and Figure 10 The fixed cylinder 22 is fixedly connected to the top of the connecting plate 7 via multiple L-shaped rods, and is located above gear I 8. A sliding seat 23 is slidably connected inside the fixed cylinder 22. A U-shaped seat 30 is fixed to the top of the sliding seat 23. A rotating column 32 is rotatably connected inside the U-shaped seat 30, and a roller 33 is fixedly sleeved on the outer wall of the rotating column 32. One end of the rotating column 32 extends rotatably to one side of the U-shaped seat 30. A one-way bearing 34 is sleeved on the outer wall of the rotating column 32. The inner ring of the one-way bearing 34 is fixedly connected to the outer wall of the rotating column 32, and gear III 35 is fixed to the outer ring of the one-way bearing 34. A fixed cylinder 36 is fixed to one side of the U-shaped seat 30. A piston rod 37 is slidably connected inside the fixed cylinder 36. A rack 38 is fixed to the top of the piston rod 37, and the rack 38 meshes with gear III 35.

[0060] Reference Figure 1 , Figure 9 and Figure 10The drive structure also includes a hollow tube 40 that rotates on one side of the control cylinder 1. A connecting hose 39 is fixed to the outer wall of the hollow tube 40. The bottom end of the connecting hose 39 extends into the hollow tube 40, and the top end of the connecting hose 39 is fixedly connected to the bottom of the fixed cylinder 36. A coil spring 41 is sleeved on the outer wall of the hollow tube 40. The two ends of the coil spring 41 are fixedly connected to the outer wall of the hollow tube 40 and one side of the control cylinder 1 respectively through connecting seats, and are used to drive the hollow tube 40 to reset and rotate to complete the winding of the connecting hose 39. A hollow disc 42 is rotatably connected to one end of a hollow tube 40, and the hollow disc 42 is connected to the hollow tube 40. A piston plate 43 is slidably connected inside the hollow disc 42. A nut seat 44 is fixed to the side of the piston plate 43 away from the hollow tube 40 by a support rod. A reciprocating screw 45 is rotatably connected to the side of the hollow disc 42 away from the hollow tube 40, and one end of the reciprocating screw 45 extends into the hollow disc 42 and passes through the nut seat 44. A sliding block is fixed inside the nut seat 44 and slides in a spiral groove on the outer wall of the reciprocating screw 45.

[0061] In actual operation, the operator manually rotates the reciprocating screw 45, which drives the piston plate 43 to move linearly back and forth via the nut seat 44. The piston plate 43, through the connecting hose 39, extracts or injects hydraulic oil into the fixed cylinder 36, thereby controlling the reciprocating up and down movement of the rack 38. The reciprocating up and down movement of the rack 38 drives the No. III gear 35 to rotate back and forth. The No. III gear 35, through the cooperation of the rotating column 32 and the one-way bearing 34, drives the rotating column 32 and the roller 33 to rotate unidirectionally, thereby driving the adjusting sleeve 14 to gradually move towards the expansion threaded hole until the expansion bolt inside the adjusting sleeve 14 is aligned with the expansion threaded hole. This drive structure enables the automatic movement of the adjusting sleeve 14, improving installation efficiency and alignment accuracy.

[0062] Reference Figure 6 , Figure 8 and Figure 9 A No. III spring 47, with a spring constant of 50-100 N / m, abuts against the bottom of the sliding seat 23 and the inner wall of the bottom of the fixed cylinder 22. This spring is used to house the sliding seat 23 and the U-shaped seat 30 within the fixed cylinder 22. A fixed plate 26 is provided on one side of the fixed cylinder 22, and a limiting rod 25, which slides into the fixed cylinder 22, is fixed to one side of the fixed plate 26. The limiting rod 25 is used to limit the movement of the sliding seat 23. A tension spring 27, with a spring constant of 30-60 N / m, is fitted onto the outer wall of the fixed cylinder 22. Both ends of the tension spring 27 are fixedly connected to the outer wall of the fixed cylinder 22 and one side of the fixed plate 26 respectively via spring seats, for inserting the limiting rod 25 into the fixed cylinder 22. Multiple No. I magnets 28 are fixed on one side of the fixed cylinder 22, and multiple electromagnets 29 are fixed on one side of the fixed plate 26. The electromagnets 29 and No. I magnets 28 generate a repulsive force, and the repulsive force is greater than the tension of the tension spring 27.

[0063] When the roller 33 moves on the ceiling, the limiting rod 25 limits the sliding seat 23 to prevent the sliding seat 23 from retracting into the fixed cylinder 22. The repulsive force between the electromagnet 29 and the No. I magnet 28 drives the limiting rod 25 to move outward, releasing the brake on the sliding seat 23. This makes it easier to store the U-shaped seat 30 and the sliding seat 23 into the fixed cylinder 22 when the expansion bolt is screwed into the expansion thread hole later.

[0064] Reference Figure 1 , Figure 2 and Figure 4 The striking structure is used to easily insert the expansion bolt into the expansion threaded hole after the expansion bolt is aligned with it. The striking structure includes a striking post 11, a pull rod 10, and a No. I spring 12. The pull rod 10 is fixed to the bottom end of the striking post 11, and the bottom end of the pull rod 10 slides to the bottom of the rotating handle 9. The bottom of the striking post 11 and the inner wall of the bottom of the rotating handle 9 are in contact by the No. I spring 12. The spring constant of the No. I spring 12 is in the range of 80-120 N / m. The thrust applied by the No. I spring 12 to the striking post 11 strikes the operating cylinder 1, and the striking post 11 slides within the rotating handle 9.

[0065] In actual operation, the staff pulls the striking column 11 downward by pulling rod 10, and then releases the pull of rod 10. Under the elastic force of spring 12, the striking column 11 strikes the operating cylinder 1. The reciprocating operation can easily insert the expansion bolt into the expansion thread hole, which is convenient for the expansion bolt to be screwed into the expansion thread hole later.

[0066] Reference Figure 5 , Figure 8 and Figure 10 A light 24 is fixed to the side of the fixed sleeve 22 near the adjusting sleeve 14, and a light strip 31 is fixed to the side of the U-shaped seat 30 near the adjusting sleeve 14. The light strip 31 is used to provide illumination when the adjusting sleeve 14 is aligned with the expansion threaded hole, so that the staff can judge whether the expansion threaded hole and the expansion bolt are aligned.

[0067] In another embodiment: Reference Figure 6 and Figure 7An improvement upon Embodiment 1: The outer wall of the fixing ring 16 is provided with an annular groove 17. A base 18 is fixed to the bottom of the connecting plate 7. A sliding rod 19 slides through the base 18. A trapezoidal block 20 is fixed to one end of the sliding rod 19, and the trapezoidal block 20 slides on the bottom of the connecting plate 7. The trapezoidal block 20 cooperates with the annular groove 17 to position the fixing ring 16. A spring II 21 is sleeved on the outer wall of the sliding rod 19. The spring constant of spring II 21 is in the range of 40-70 N / m. Both ends of spring II 21 are fixedly connected to the base 18 and the side of the trapezoidal block 20 that are close to each other via spring seats. The fixing ring 16 is passed through the connecting plate 7. Under the action of spring II 21, the trapezoidal block 20 extends into the annular groove 17, and the right-angled side of the trapezoidal block 20 cooperates with the annular groove 17 to limit the fixing ring 16, thereby completing the installation of the connecting plate 7 and the fixing ring 16.

[0068] A method for installing ceiling hanger tools includes the following steps:

[0069] S1. In use, connect the expansion bolt to the boom, and then install the adjusting sleeve 14 that mates with the expansion bolt to the connecting plate 7. Specifically, the fixing ring 16 passes through the connecting plate 7, and the trapezoidal block 20 extends into the annular groove 17 under the action of spring II 21. The right-angled side of the trapezoidal block 20 mates with the annular groove 17 to limit the fixing ring 16. When the fixing ring 16 passes through the connecting plate 7, the adjusting sleeve 14 and gear II 13 slide together through the groove and the slider. Therefore, gear II 13 can drive the adjusting sleeve 14 to rotate later. Then, pass one end of the boom through the hexagonal groove 15 and the through hole 46 in sequence, and the one end of the expansion bolt mates with the hexagonal groove 15.

[0070] S2. Loosen the positioning bolt 4 so that one end of the positioning bolt 4 is disengaged from the positioning groove 3. Pull the connecting cylinder 2 out of the operating cylinder 1. Adjust the extension length of the connecting cylinder 2 according to the height of the ceiling. The positioning of the connecting cylinder 2 is completed by the cooperation of the positioning bolt 4 and the positioning groove 3.

[0071] S3. Due to the high ceiling, it is difficult for workers to position the expansion bolts with the previously completed bolt holes on the ceiling when operating the control cylinder 1 and connecting cylinder 2 from the ground. Therefore, the control cylinder 1 and connecting cylinder 2 can be raised vertically so that the roller 33 touches the ceiling. The connecting cylinder 2 is rotated according to the relative position of the expansion bolt and bolt hole inside the adjusting sleeve 14 to align the adjusting sleeve 14 with the bolt hole. Then, the reciprocating screw 45 is manually rotated. The reciprocating screw 45 drives the piston plate 43 to move reciprocally in a straight line through the nut seat 44. The piston plate 43, through the cooperation of the connecting hose 39, completes the fixation of the liquid inside the cylinder 36. The extraction or injection of pressurized oil controls the reciprocating up and down movement of rack 38, which in turn drives gear III 35 to rotate reciprocally. Gear III 35, through the cooperation of rotating column 32 and one-way bearing 34, can drive rotating column 32 and roller 33 to rotate in one direction, which can drive adjusting sleeve 14 to gradually move towards expansion thread hole until the expansion bolt in adjusting sleeve 14 is aligned with the expansion thread hole. In addition, during the movement, the cooperation of lighting lamp 24 and light strip 31 can provide illumination for the alignment of expansion bolt and bolt hole, avoiding the inability to accurately judge whether expansion bolt and bolt hole are aligned in poor light conditions.

[0072] S4. By controlling the electromagnet 29 to be energized by the button on one side of the control cylinder 1, the magnetic force between the electromagnet 29 and the No. I magnet 28 drives the limit rod 25 to move outward, releasing the brake on the sliding seat 23. Then, the control cylinder 1, the connecting cylinder 2 and the connecting plate 7 are pushed upward, and the expansion bolt is pushed into the bolt hole. The U-shaped seat 30 and the roller 33 are stored in the fixed cylinder 22. In addition, in order to ensure that the expansion bolt can be screwed into the expansion thread hole smoothly, the control cylinder 1 needs to be pushed into the expansion thread hole to a certain depth before driving the expansion bolt to rotate. Specifically, the striking column 11 is pulled down by the pull rod 10, and then the pull rod 10 is released. The striking column 11 strikes the control cylinder 1 under the elastic force of the No. I spring 12. The reciprocating operation can easily insert the expansion bolt into the expansion thread hole.

[0073] S5. Next, the rotating handle 9 drives the rotating cylinder 5 to rotate. The rotating cylinder 5 drives the No. I gear 8 to rotate through the sliding rod 6. The radius of the No. I gear 8 is larger than the radius of the No. II gear 13. The No. I gear 8 can easily drive the No. II gear 13 to rotate. The No. II gear 13 drives the expansion bolt inside it to rotate through the adjusting sleeve 14, thereby completing the installation of the expansion bolt and the expansion thread hole, and then completing the installation of the hanging rod and the ceiling. After the installation is completed, the connecting cylinder 2 is stored in the operating cylinder 1. When storing, the coil spring 41 drives the hollow tube 40 to rotate, completing the winding of the connecting hose 39.

[0074] However, as is well known to those skilled in the art, the working principle and wiring method of electromagnet 29 are commonplace and are all conventional methods or common knowledge, so they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0075] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0076] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
