Description

Technical Field

[0001] This application relates to the field of workpiece mounting devices, and in particular to a support structure for fine-tuning the angle of a workpiece to be mounted. Background Technology

[0002] The refuge floor features a partially externally projecting reinforced concrete structure, most of which is attached to the bay window sill beam. Traditional construction techniques involve pre-embedding box-shaped structures during the main construction phase to create through-wall openings, then installing cantilevered I-beams as scaffold supports. However, these openings require sealing later, which can easily lead to leaks.

[0003] The commonly used construction method involves fixing the cantilever bracket to the bay window sill using steel plates and bolts. The cantilever bracket consists of two I-beam supports: a horizontal support and a diagonal brace fixed to the bottom of the horizontal support. Steel pads are installed on both the upper and lower bay window sills, and high-strength bolts are used to secure the steel pads to the bay window sills. Steel square tubes are then welded onto the steel pads. Finally, the two I-beam supports are welded to the two steel square tubes, thus completing the installation of the cantilever bracket. However, during the welding process between the I-beam supports and the steel square tubes, the I-beam supports are prone to tilting, resulting in poor stability of the cantilever bracket. Summary of the Invention

[0004] To address the issue of misalignment that easily occurs during the welding process between the I-beam support and the square steel tube, this application provides a support structure for fine-tuning the angle of the workpiece to be installed.

[0005] The technical solution provided in this application for a workpiece angle fine-tuning support structure is as follows:

[0006] A support structure for fine-tuning the angle of a workpiece to be installed includes a mounting frame, which is fixedly connected to a steel square tube. The mounting frame includes a mounting plate located on the top surface of a bay window panel. Two limiting plates are slidably mounted on the top surface of the mounting plate. A mounting block is fixed on the bottom surface of the limiting plate. A mounting groove is formed on the top surface of the mounting plate. The mounting block slides and engages with the mounting plate along its length through the mounting groove. A pushing component is provided on the mounting plate for pushing the two mounting blocks to move towards each other. Limiting blocks are fixed on the sides of the two limiting plates that are close to each other. The limiting blocks are used to insert into the grooves of the I-beam support. Abutment grooves are formed on the top and bottom surfaces of the limiting blocks. Abutment blocks are slidably mounted on the limiting blocks along the vertical direction through the abutment grooves. The abutment blocks abut against the inner wall of the groove of the I-beam support. A driving component is provided inside the limiting blocks for pushing the abutment blocks to move in opposite directions.

[0007] By adopting the above technical solution, the mounting bracket is first fixed to the steel square tube, the mounting plate is placed on the top surface of the protruding wall panel, and the I-beam support is located between the two limiting plates. The pushing component is used to drive the two limiting plates to move towards the I-beam support, so that the limiting block is inserted into the groove of the I-beam support. Then, the driving component is used to drive the abutment block to move away from the limiting block, so that the abutment block abuts against the inner wall of the groove of the I-beam support, thereby limiting the I-beam support, so that the construction personnel can weld and fix the I-beam support to the steel square tube.

[0008] Preferably, the limiting block is provided with a rotating cavity communicating with the abutment groove, the driving component includes a bidirectional screw first rotatably installed in the rotating cavity, the abutment block is sleeved on the outer periphery of the bidirectional screw first, the abutment block and the bidirectional screw first are threadedly driven together, and the limiting block is provided with a rotating component for driving the bidirectional screw first to rotate.

[0009] By adopting the above technical solution, the rotating component drives the bidirectional screw to rotate, and the bidirectional screw drives the two abutting blocks to move away from the limiting block, thereby making the abutting blocks abut against the inner wall of the groove of the I-beam support, thus limiting the I-beam support in the vertical direction.

[0010] Preferably, the rotating component includes a bevel gear one rotatably mounted in the rotating cavity, the bevel gear being sleeved and fixed to the outer periphery of the bidirectional screw one, an adjustment cavity being provided on the side of the limiting plate away from the limiting block, an adjustment rod being rotatably mounted in the adjustment cavity, and a bevel gear two being sleeved and fixed to the outer periphery of the adjustment rod, the bevel gear two meshing with the bevel gear one.

[0011] By adopting the above technical solution, rotating the adjusting rod causes the second bevel gear to rotate, which in turn causes the first bevel gear to rotate, which in turn causes the first double-acting screw to rotate, thereby moving the abutment block.

[0012] Preferably, the pushing assembly includes a second bidirectional screw rotatably mounted in the mounting groove, a motor mounted on the mounting plate, and the output end of the motor fixedly connected to the end of the second bidirectional screw; a mounting block is sleeved on the outer periphery of the second bidirectional screw, and a mounting cavity is provided in the mounting block. A connecting cylinder is rotatably mounted in the mounting cavity, and the connecting cylinder is sleeved on the outer periphery of the second bidirectional screw. The second bidirectional screw and the connecting cylinder are threadedly engaged. A control groove is provided on the bottom surface of the mounting block, and a control block is mounted on the mounting block by sliding vertically through the control groove. A connecting groove for inserting the control block is provided on the outer periphery of the connecting cylinder.

[0013] By adopting the above technical solution, the control block is inserted into the connecting groove, so that the connecting cylinder and the mounting block remain relatively fixed. The motor is started, and the motor drives the double-headed screw to rotate. The double-headed screw drives the two mounting blocks to move in a direction that brings them closer to each other, thereby driving the limiting block into the groove of the I-beam support. This allows both limiting blocks to abut against the inner wall of the groove of the I-beam support, thereby achieving horizontal limiting of the I-beam support.

[0014] Preferably, a magnetic block is fixed on the bottom surface of the control block, and an electromagnet is embedded and fixed on the inner bottom surface of the mounting groove. When the electromagnet is energized, it repels the magnetic block. A battery and a switch are installed on the top surface of the mounting plate. The battery is electrically connected to the switch, and the switch is electrically connected to the electromagnet.

[0015] By adopting the above technical solution, when the switch is turned on, the electromagnet is energized and works. The magnetic block moves upward under the repulsive force of the electromagnet, and the magnetic block drives the control block to move upward, thereby causing the control block to be inserted into the connecting groove. The bidirectional screw drives the two mounting blocks to move towards each other.

[0016] Preferably, a slider is fixed to the side of the control block, a groove is provided on the inner wall of the control slot, the slider slides vertically with the mounting block through the groove, and a sliding spring is fixed to the bottom surface of the slider, the bottom end of the sliding spring is fixedly connected to the inner bottom surface of the groove.

[0017] By adopting the above technical solution, when the switch is turned off, the electromagnet is de-energized, and the control block moves downward under the elastic force of the sliding spring, thereby causing the control block to disengage from the connecting groove. The bidirectional screw drives the connecting cylinder to rotate synchronously, and the mounting plate stops moving.

[0018] Preferably, a movable groove is formed on the side of the limiting block away from the limiting plate. A movable block is slidably mounted on the limiting block along the length direction of the mounting plate through the movable groove. A movable spring is fixed on the side of the movable block near the limiting plate. The end of the movable spring away from the movable block is fixedly connected to the inner wall of the movable groove. A movable contact piece is embedded and fixed on the side of the movable block. A fixed contact piece for electrical contact with the movable contact piece is embedded and fixed on the inner wall of the movable groove. The movable contact piece is electrically connected to the electromagnet, and the fixed contact piece is electrically connected to the battery.

[0019] By adopting the above technical solution, when the limiting block is not in contact with the inner wall of the groove of the I-beam support, the moving block extends out of the moving slot under the action of the moving spring, the moving contact and the fixed contact make electrical contact, the electromagnet is energized and works, so that the limiting block continues to move towards the I-beam support; when one of the limiting blocks abuts against the inner wall of the groove of the I-beam support, and the other limiting block does not abut against the inner wall of the groove of the I-beam support, the electromagnet remains energized, and the two limiting blocks continue to move towards each other; when both limiting blocks are in contact with the inner wall of the groove of the I-beam support, the moving contact separates from the corresponding fixed contact, and the switch is in the closed state, the electromagnet is de-energized, the limiting blocks stop moving, and the two limiting blocks limit the I-beam support in the horizontal direction.

[0020] Preferably, the top surface of the mounting plate has two vertical baffles fixed, and a snap-fit ​​plate is fixed to the side of the vertical baffles near the steel square tube. A snap-fit ​​block is fixed to the side of the snap-fit ​​plate near the steel square tube. The snap-fit ​​block fits against the side of the steel square tube. A snap-fit ​​groove is opened on the side of the two snap-fit ​​blocks that are close to each other. A positioning block is installed on the snap-fit ​​block along the length direction of the mounting plate through the snap-fit ​​groove. The positioning block is used to abut against the side of the steel square tube away from the mounting plate. A pressure plate is fixed to the bottom surface of the mounting plate, and a snap-fit ​​plate is fixed to the side of the pressure plate near the steel square tube.

[0021] By adopting the above technical solution, the mounting plate is placed on the top surface of the convex wall panel, the snap-fit ​​plate is located on the bottom surface of the convex wall panel, the pressure plate is attached to the side of the convex wall panel, the two snap-fit ​​plates are located on both sides of the steel square tube, the snap-fit ​​block is attached to the side of the steel square tube, and the positioning block is attached to the side of the steel square tube away from the mounting plate, thereby fixing the relative position of the mounting plate and the steel square tube.

[0022] Preferably, a reset block is fixed to the side of the positioning block, and a reset groove is provided on the inner wall of the snap-fit ​​groove. The reset block slides and engages with the positioning block along the length of the mounting plate through the reset groove. A reset spring is fixed to the side of the reset block away from the steel square tube, and the end of the reset spring away from the reset block is fixedly connected to the inner wall of the reset groove.

[0023] By adopting the above technical solution, the positioning block is moved into the snap-fit ​​groove so that the snap-fit ​​block can fit with the steel square tube. Then the positioning block is released, and under the elastic force of the return spring, the positioning block moves towards the steel square tube, so that the positioning block fits with the side of the steel square tube away from the mounting plate.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. First, fix the mounting bracket to the steel square tube. Place the mounting plate on the top surface of the protruding wall panel. The I-beam support is located between the two limiting plates. Use the pushing component to move the two limiting plates toward the I-beam support, so that the limiting block is inserted into the groove of the I-beam support. Then use the driving component to move the abutting block away from the limiting block, so that the abutting block abuts against the inner wall of the groove of the I-beam support, thereby limiting the I-beam support, so that the construction personnel can weld and fix the I-beam support to the steel square tube.

[0026] 2. Insert the control block into the connecting groove so that the connecting cylinder and the mounting block remain relatively fixed. Start the motor. The motor drives the double-headed screw to rotate. The double-headed screw drives the two mounting blocks to move towards each other, thereby driving the limit block into the groove of the I-beam support. This ensures that both limit blocks abut against the inner wall of the groove of the I-beam support, thereby limiting the horizontal movement of the I-beam support.

[0027] 3. When the limiting block is not in contact with the inner wall of the groove of the I-beam support, the moving block extends out of the moving slot under the action of the moving spring, the moving contact and the fixed contact make electrical contact, the electromagnet is energized and works, so that the limiting block continues to move towards the I-beam support; when one of the limiting blocks abuts against the inner wall of the groove of the I-beam support, and the other limiting block does not abut against the inner wall of the groove of the I-beam support, the electromagnet remains energized, and the two limiting blocks continue to move towards each other; when both limiting blocks are in contact with the inner wall of the groove of the I-beam support, the moving contact separates from the corresponding fixed contact, and the switch is in the closed state, the electromagnet is de-energized, the limiting blocks stop moving, and the two limiting blocks limit the I-beam support in the horizontal direction.

[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0036] This application discloses a support structure for fine-tuning the angle of a workpiece to be installed. (Refer to...) Figure 1 and Figure 2 The workpiece angle fine-tuning support structure includes a mounting frame 1, which includes a mounting plate 11 and a pressure plate 12 fixed to the bottom surface of the mounting plate 11. A locking plate 13 is fixed to the side of the pressure plate 12 near the steel square tube. The mounting frame 1 is locked to the bay window panel, with the mounting plate 11 located on the top surface of the bay window panel, the pressure plate 12 abutting against the side of the bay window panel, and the top surface of the locking plate 13 fitting against the bottom surface of the bay window panel, thereby making the bottom surface of the mounting plate 11 fit against the top surface of the bay window panel and maintaining the stability of the mounting plate 11.

[0037] Reference Figure 2 and Figure 3Two vertically arranged baffles 14 are fixed to the top surface of the mounting plate 11. A snap-fit ​​plate 15 is fixed to the side of the baffles 14 near the steel square tube. A snap-fit ​​block 2 is fixed to the side of the snap-fit ​​plate 15 near the steel square tube, with the two snap-fit ​​blocks 2 located on opposite sides of the steel square tube and abutting against the steel square tube. A snap-fit ​​groove 21 is provided on the side of the snap-fit ​​block 2 near the steel square tube. A positioning block 22 is slidably mounted on the snap-fit ​​block 2 along the length of the mounting plate 11 via the snap-fit ​​groove 21. The positioning block 22 abuts against the side of the steel square tube away from the mounting plate 11. Reset blocks 23 are fixed to both sides of the positioning block 22. A reset groove 24 is provided on the inner wall of the snap-fit ​​groove 21. The reset block 23 slides along the length of the mounting plate 11 and is connected to the positioning block 22 via the snap-fit ​​groove 21. A reset spring 25 is fixed to the side of the reset block 23 away from the steel square tube. The end of the reset spring 25 away from the reset block 23 is fixedly connected to the inner wall of the reset groove 24 away from the steel square tube.

[0038] After the mounting plate 11 is attached to the protruding wall panel, it is moved toward the direction closer to the steel square tube. The positioning block 22 is moved toward the direction away from the steel square tube, so that the positioning block 22 moves into the snap-fit ​​groove 21, so that the snap-fit ​​block 22 is attached to the steel square tube. Then the positioning block 22 is released. Under the elastic force of the return spring 25, the positioning block 22 moves toward the direction closer to the steel square tube, so that the positioning block 22 abuts against the side of the steel square tube away from the mounting plate 11. At this time, the pressing plate 12 abuts against the side of the protruding wall panel away from the steel square tube, so that the mounting plate 11 and the steel square tube are snapped and fixed.

[0039] Reference Figure 3 and Figure 4 The top surface of the mounting plate 11 has a mounting groove 41, and a double-acting screw 4 is rotatably mounted in the mounting groove 41. A motor 42 is fixed to the side of the mounting plate 11, and the output end of the motor 42 is fixedly connected to the end of the double-acting screw 4. Two mounting blocks 5 are slidably mounted on the mounting plate 11 along its own length direction through the mounting groove 41. The mounting blocks 5 are sleeved on the outer periphery of the double-acting screw 4, and the double-acting screw 4 can drive the two mounting blocks 5 to move towards each other. A vertically set limiting plate 3 is fixed to the top surface of the mounting block 5, and limiting blocks 31 are fixed to the sides of the two limiting plates 3 that are close to each other. The limiting blocks 31 can be inserted into the groove of the I-beam support, thereby limiting the I-beam support.

[0040] Reference Figure 3 and Figure 4The limiting block 31 has a rotating cavity 32, within which a vertically mounted bidirectional screw 33 is rotatably installed. Each end of the bidirectional screw 33 is fitted with an abutment block 34, which engages with the bidirectional screw 33 via a threaded connection. The top and bottom surfaces of the limiting block 31 have abutment grooves 35, through which the abutment blocks 34 slide vertically against the limiting block 31. The side of the limiting plate 3 away from the limiting block 31 has an adjusting cavity 36, within which an adjusting rod 37 is rotatably installed. The end of the adjusting rod 37 away from the bidirectional screw 33 extends out of the limiting plate 3 and is fixed with a handle 371. A bevel gear 38 is fitted and fixed to the outer circumference of the bidirectional screw 33, and a bevel gear 39 is fitted and fixed to the outer circumference of the adjusting rod 37. The bevel gear 38 and bevel gear 39 mesh with each other.

[0041] When the limiting block 31 abuts against the inner wall of the I-beam support frame, the limiting block 31 limits the horizontal position of the I-beam support. Turning the handle 371 drives the adjusting rod 37 to rotate, which in turn drives the bevel gear 39 to rotate. The bevel gear 39 drives the bevel gear 38 to rotate, which in turn drives the double screw 33 to rotate. The double screw 33 pushes the two abutting blocks 34 to move away from each other, so that the abutting blocks 34 abut against the inner wall of the I-beam support, thereby limiting the vertical position of the I-beam support.

[0042] Reference Figure 2 and Figure 5 The mounting block 5 has a mounting cavity 52, within which a connecting cylinder 51 is rotatably mounted. The connecting cylinder 51 is fitted onto the outer circumferential surface of the double-acting screw 4, and the connecting cylinder 51 and the double-acting screw 4 are threadedly engaged. A control groove 53 is formed on the bottom surface of the mounting block 5, through which a control block 54 is vertically slidably mounted. A connecting groove 55 for insertion is formed on the outer circumferential surface of the connecting cylinder 51. Slider blocks 57 are fixed to both sides of the control block 54. A sliding groove 56 is formed on the inner wall of the control groove 53, through which the sliders 57 slide vertically to the connecting cylinder 51. A sliding spring 58 is fixed to the bottom surface of the slider 57, and the bottom end of the sliding spring 58 is fixedly connected to the inner bottom surface of the sliding groove 56. A magnet 44 is fixed to the bottom surface of the control block 54, and an electromagnet 43 is embedded in the inner bottom surface of the mounting groove 41. When energized, the electromagnet 43 repels the magnet 44. A battery 45 and a switch 46 are mounted on the top surface of the mounting plate 11. The battery 45 is electrically connected to the switch 46, and the switch 46 is electrically connected to the electromagnet 43.

[0043] When switch 46 is turned on, electromagnet 43 is energized and operates. Magnetic block 44 moves upward under the repulsive force of electromagnet 43, thereby inserting control block 54 into connecting groove 55. At this time, bidirectional screw 4 can drive mounting block 5 to move. When switch 46 is turned off, electromagnet 43 stops operating, and control block 54 moves downward under the elastic force of sliding spring 58, thereby disengaging control block 54 from connecting groove 55. Connecting cylinder 51 rotates synchronously with bidirectional screw 4, and mounting block 5 stops moving.

[0044] Reference Figure 3 and Figure 6 Two limiting blocks 31 have movable grooves 61 on their adjacent sides. Movable blocks 6 are mounted on the limiting blocks 31 by sliding along the length of the mounting plate 11 through the movable grooves 61. A movable spring 62 is fixed to the side of the movable block 6 closest to the limiting plate 3, and the end of the movable spring 62 away from the movable block 6 is fixedly connected to the inner wall of the movable groove 61. A movable contact 63 is embedded and fixed on the top surface of the movable block 6, and a fixed contact 64 is embedded and fixed on the inner top surface of the movable groove 61. The fixed contact 64 can make electrical contact with the movable contact 63. The movable contact 63 is electrically connected to the electromagnet 43, and the fixed contact 64 is electrically connected to the battery 45.

[0045] When motor 42 is started, switch 46 is in the closed state. Moving contact 63 and fixed contact 64 are in electrical contact, electromagnet 43 is energized, and control block 54 is inserted into connecting slot 55. The two limit blocks 31 move towards the I-beam support. When limit block 31 abuts against the inner wall of the groove of the I-beam support, fixed contact 64 separates from moving contact 63. When one limit block 31 abuts against the inner wall of the groove of the I-beam support, and the other limit block 31 is not abutting against the I-beam support... When the inner wall of the groove abuts against each other, the electromagnet 43 remains energized, and the two limit blocks 31 continue to move toward the direction of the I-beam support; when both limit blocks 31 abut against the inner wall of the groove of the I-beam support, the fixed contact 64 separates from the corresponding moving contact 63, the electromagnet 43 is de-energized, the control block 54 disengages from the connecting groove 55 under the elastic force of the sliding spring 58, and the mounting block 5 stops moving, thereby reducing the possibility of the limit blocks 31 squeezing the I-beam support.

[0046] The implementation principle of the workpiece angle fine-tuning support structure in this application embodiment is as follows: After the mounting frame 1 is engaged with the protruding wall plate, the positioning block 22 is then abutted against the steel square tube, so that the positions of the mounting frame 1 and the steel square tube remain relatively fixed; then the motor 42 is started, and the two-way screw 4 drives the two mounting blocks 5 to move towards the direction close to the I-beam support. After the limiting block 31 abuts against the inner wall of the groove of the I-beam support, the adjusting rod 37 is rotated so that the abutting block 34 abuts against the groove of the I-beam support, thereby limiting the I-beam support, so that the construction personnel can weld the I-beam support and the steel square tube; after the welding is completed, the switch 46 is turned on, the electromagnet 43 is energized, the control block 54 is inserted into the connecting groove 55, and the motor 42 is started to reverse, so that the limiting block 31 is separated from the I-beam support, so that the construction personnel can remove the mounting frame 1.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
