Description

Technical Field

[0001] This invention relates to the field of high-altitude work equipment technology, specifically an operating platform for chimney exterior wall anti-corrosion construction. Background Technology

[0002] After the chimney is built, in order to improve the protective ability of its outer wall, it is often necessary to apply protective coating to its outer wall. At present, the application of anti-corrosion coating is mainly carried out manually. The operator needs to stand on the operating platform, which is hoisted by the hoisting equipment installed from the top of the chimney.

[0003] In order to improve the stability of operation, the existing chimney exterior wall anti-corrosion construction operation platform is often designed to be in contact with the construction platform exterior wall through abutment wheels. However, due to the structural design of the chimney exterior wall, its verticality is not maintained at 90 degrees with the ground. This makes it impossible for the operation platform to maintain a vertical and stable state during construction and lifting, thus affecting the safety of personnel. Summary of the Invention

[0004] The purpose of this invention is to provide an operating platform for chimney exterior wall anti-corrosion construction, which solves the problem that existing chimney exterior wall anti-corrosion construction operating platforms designed for personnel to stand on are often designed to abut against the construction platform exterior wall through abutment wheels. Since the chimney exterior wall is not perpendicular to the ground at 90 degrees, the operating platform cannot maintain a vertical and stable state during construction and lifting, thus affecting the safety of personnel during construction.

[0005] To achieve the above objectives, the present invention provides an operating platform for chimney exterior wall anti-corrosion construction, comprising:

[0006] There are two sets of operating platforms, each equipped with a hanging ring fixedly connected to a hanging rope. The near ends of the two sets of operating platforms are rotatably connected to the upper end of a mounting base plate. A set of drive seats is slidably mounted on the mounting base plate. The drive seats are driven to slide linearly by a power component on the mounting base plate. Both ends of the mounting base plate are respectively connected to the transmission columns at the bottom of the operating platforms through corresponding transmission components. The linear movement of the drive seats drives the two sets of operating platforms to rotate.

[0007] Two sets of counterweight boxes are fixedly installed at the bottom of the corresponding operating platform.

[0008] There are two sets of abutting main wheels, which are rotatably installed on the side of the corresponding operating platform near the outer wall of the chimney, for abutting against the wall surface of the chimney.

[0009] The positioning wheels are arranged in two sets and are rotatably mounted on the positioning rods set on the corresponding operating platform. The positioning rods are slidably connected to the positioning frames set on the operating platform and are elastically connected to the bottom of the positioning frames through elastic elements. The positioning frames are provided with locking structures for locking the positioning rods.

[0010] As a further embodiment of the present invention, a protective claw post is provided near the end of the operating table, and two sets of protective claw posts near the operating table are staggered, and the protective frame is fixedly installed on the periphery of the operating table.

[0011] As a further embodiment of the present invention, a connecting column is fixedly installed at the bottom corner of the operating table near the end, and the connecting column is rotatably connected to one end of the mounting base plate.

[0012] As a further embodiment of the present invention, multiple sets of fixing columns are fixedly installed parallel to the bottom of the mounting base plate, and the drive seat is provided with positioning through holes that are slidably connected to the multiple sets of fixing columns.

[0013] As a further embodiment of the present invention, the power assembly includes a first drive screw and a stepper motor. The first drive screw is rotatably mounted on the bottom of the mounting base plate, and one end of it is connected to the output shaft of the stepper motor at the bottom of the mounting base plate. The drive seat is provided with a fixed threaded cap that forms a helical pair with the first drive screw.

[0014] As a further embodiment of the present invention, the transmission component is a transmission plate, and one end of the two sets of transmission plates is rotatably connected to the fixed columns fixedly installed at both ends of the drive seat, and the other end is rotatably connected to the corresponding transmission column.

[0015] As a further embodiment of the present invention, the positioning frame is fixedly installed at the far end of the two sets of operating tables, and has a sliding cavity for the positioning rod to slide through. The elastic element is a connecting spring, one end of which is fixedly connected to the end of the positioning rod inserted into the sliding cavity, and the other end is fixedly connected to the bottom of the sliding cavity. The connecting spring is used to provide support elasticity for the positioning column to slide out of the positioning frame.

[0016] As a further embodiment of the present invention, the locking structure includes a locking rack and a fixing toothed plate. The fixing toothed plate is fixedly installed on one side of the positioning post. The locking rack is slidably installed in the positioning frame through multiple sets of guide posts and is driven to move linearly by a second threaded rod rotatably installed on the side plate of the positioning frame.

[0017] Compared with existing technologies, this invention sets up two sets of operating platforms, a counterweight box, abutting main wheels, and positioning slave wheels. The near ends of the two sets of operating platforms are rotatably connected to the mounting base plate. At the same time, the drive seat mounted on the mounting base plate slides linearly, causing the corresponding operating platform to deflect. This allows the included angle parameter of the two sets of operating platforms to be adjusted according to the arc specifications of the chimney's outer wall, making the operating platform fit the chimney's outer wall more closely. Simultaneously, the weight of the counterweight box, combined with the abutting main wheels, abuts against the chimney's outer wall, maintaining the operating platform in a vertical state. At this point, the positioning rod can be unlocked. The positioning rod extends out of the positioning frame and slides against the chimney's outer wall before locking, thereby increasing the fulcrum of the operating platform and improving its stability. This solves the problem that existing chimney outer wall anti-corrosion construction operating platforms designed for personnel to stand on are often designed to abut against the construction platform's outer wall through abutting wheels. Since the verticality of the chimney's outer wall is not always 90 degrees perpendicular to the ground, the operating platform cannot maintain a vertical and stable state during construction and lifting, thus affecting the safety of personnel during construction.

[0024] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0025] like Figure 1 , Figure 3 as well as Figure 4As shown in this embodiment of the invention, an operating platform for chimney exterior wall anti-corrosion construction includes two sets of operating platforms 1. Each set has a hanging ring fixedly connected to a hanging rope 15. The near ends of the two sets of operating platforms 1 are rotatably connected to the upper end of a mounting base plate 2. A set of drive seats 10 is slidably mounted on the mounting base plate 2. The drive seats 10 are linearly slidable by a power component on the mounting base plate 2. Both ends of the mounting base plate 2 are respectively connected to a transmission column at the bottom of the operating platform 1 via corresponding transmission components. The linear movement of the drive seats 10 drives the two sets of operating platforms 1. Platform 1 rotates; counterweight boxes 9, in two sets, are fixedly installed at the bottom of the corresponding operating platform 1; abutting main wheels 7, in two sets, are rotatably installed on the side of the corresponding operating platform 1 near the outer box of the chimney outer wall 6, for abutting against the wall surface of the chimney outer wall 6; positioning wheels 8, in two sets, are rotatably installed on the positioning rods 16 set on the corresponding operating platform 1, the positioning rods 16 are slidably connected to the positioning frame 17 set on the operating platform 1, and are elastically connected to the bottom of the positioning frame 17 through elastic elements, the positioning frame 17 is provided with a locking structure 14 for locking the positioning rods 16;

[0026] Specifically, in this invention:

[0027] 1. By rotating two sets of operating platforms 1 onto the mounting base plate 2, and simultaneously driving the drive seat 10 mounted on the mounting base plate 2 to slide linearly, and cooperating with two sets of transmission components to drive the corresponding operating platform 1 to deflect, the included angle parameter of the two sets of operating platforms 1 can be adjusted according to the arc specification of the chimney outer wall 6, so that the operating platform 1 fits the chimney outer wall 6 better, making it easier for personnel to carry out anti-corrosion construction operations.

[0028] 2. By setting the abutting main wheel 7 and the positioning slave wheel 8 on the side of the operating platform 1, the operating platform 1 is kept vertical during the hanging process by the weight of the counterweight box 9 and the abutting main wheel 7 abutting against the outer wall 6 of the chimney. At the same time, the positioning rod 16 connected to the positioning slave wheel 8 is unlocked. Under the elastic action of the elastic element, the positioning rod 16 extends out of the positioning frame 17 and slides against the outer wall 6 of the chimney. At the same time, the locking structure 14 locks the positioning rod 16, realizing the two-point positioning frame 17 of the abutting main wheel 7 and the positioning slave wheel 8, and realizing the locking of the operating platform 1.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment of the invention, the operating platform 1 is provided with a protective claw post 3 near its end. The protective claw posts 3 of the two sets of operating platforms 1 near their respective sides are staggered. The protective frame is fixedly installed on the periphery of the operating platform 1. By providing the protective claw posts 3, the openings of the two sets of operating platforms 1 near their respective sides are protected. Because the protective claw posts 3 are staggered, the protective claw posts 3 are prevented from getting stuck when the operating platform 1 is rotated, thus avoiding affecting the normal deflection and movement of the operating platform 1.

[0030] like Figure 1 As shown, in this embodiment of the invention, a connecting column 5 is fixedly installed at the bottom corner of the near end of the operating table 1. The connecting column 5 is rotatably connected to one end of the mounting base plate 2. The invention designs two sets of rounded corners of the near end of the operating table 1 to abut against each other, so as to avoid gaps appearing at the corners of the near end of the operating table 1 when the operating table 1 rotates, which would affect the safety of personnel operation.

[0031] like Figure 3 As shown, in this embodiment of the invention, multiple sets of fixing columns 12 are fixedly installed parallel to the bottom of the mounting base plate 2. The drive seat 10 is provided with positioning through holes that are slidably connected to the multiple sets of fixing columns 12. When the power component drives the drive seat 10 to slide linearly, the drive seat 10 slides with the multiple sets of fixing columns 12 to improve the stability of the drive seat 10 when sliding linearly.

[0032] Furthermore, the power assembly includes a first drive screw 11 and a stepper motor 13. The first drive screw 11 is rotatably mounted on the bottom of the mounting base plate 2, and one end of it is connected to the output shaft of the stepper motor 13 at the bottom of the mounting base plate 2. The drive seat 10 is provided with a fixed thread cap that forms a helical pair transmission with the first drive screw 11. The output shaft of the stepper motor 13 is directly coaxially fixedly connected to one end of the first drive screw 11 through a coupling. The stepper motor 13 starts and drives the first drive screw 11 to rotate, and the threaded transmission drives the drive shaft to move linearly.

[0033] Of course, in actual design, the power component can also be replaced with other components with linear drive capability, such as telescopic hydraulic cylinders and other structures.

[0034] like Figure 3 As shown, in this embodiment of the invention, the transmission component is a transmission plate 4. One end of the two sets of transmission plates 4 is rotatably connected to the fixed columns 12 fixedly installed at both ends of the drive seat 10, and the other end is rotatably connected to the corresponding transmission column. When the drive seat 10 is driven to move linearly by the power component, the transmission plate 4 rotates, which drives the operating table 1 to rotate around the connecting column 5, thereby adjusting the angle between the two sets of operating tables 1.

[0035] like Figure 4 and Figure 5As shown, in this embodiment of the invention, the positioning frame 17 is fixedly installed at the far end of the two sets of operating platforms 1, and has a sliding cavity for the positioning rod 16 to slide through. The elastic element is a connecting spring 18. One end of the connecting spring 18 is fixedly connected to the end of the positioning rod 16 inserted into the sliding cavity, and the other end is fixedly connected to the bottom of the sliding cavity. The connecting spring 18 is used to provide support elastic force for the positioning rod to slide out of the positioning frame 17. In this invention, when the weight of the counterweight box 9 abuts against the main wheel 7 and the outer wall of the chimney 6, keeping the operating platform 1 vertical, the positioning rod 16 can be unlocked. Under the elastic action of the connecting spring 18, the positioning rod 16 extends out of the positioning frame 17 and slides against the outer wall of the chimney 6. Then, the locking structure 14 locks the positioning rod 16, thereby increasing the fulcrum of the operating platform 1 and improving the stability of the operating platform 1.

[0036] The locking structure 14 includes a locking rack 142 and a fixing toothed plate 141. The fixing toothed plate 141 is fixedly installed on one side of the positioning post. The locking rack 142 is slidably installed in the positioning frame 17 through multiple sets of guide posts 20, and is driven to move linearly by a second threaded rod 19 rotatably installed on the side plate of the positioning frame 17. After the positioning rod 16 extends to the positioning stroke, the operator manually grasps the second threaded rod 19, which, in conjunction with the multiple sets of guide posts 20, slides and guides the locking rack 142 to move closer to the fixing toothed plate 141 until it engages and locks with the fixing toothed plate 141, thereby locking the positioning rod 16. Of course, in actual design, the locking structure 14 can also be replaced with other components such as those with self-locking structures. The designer can make the appropriate selection while ensuring the locking strength.

[0037] In summary, this invention, by setting up two sets of operating platforms 1, a counterweight box 9, abutting main wheels 7, and positioning driven wheels 8, rotatably connects the near ends of the two sets of operating platforms 1 to the mounting base plate 2. Simultaneously, the drive seat 10 mounted on the mounting base plate 2 slides linearly, causing the corresponding operating platform 1 to deflect. This allows the included angle parameter of the two sets of operating platforms 1 to be adjusted according to the arc specifications of the chimney outer wall 6, making the operating platform 1 fit more closely to the chimney outer wall 6. Furthermore, the gravity of the counterweight box 9, combined with the abutting main wheels 7, abuts against the chimney outer wall 6, maintaining the vertical position of the operating platform 1. Once in the straight position, the positioning rod 16 can be unlocked. The positioning rod 16 extends out of the positioning frame 17 and slides against the outer wall 6 of the chimney to lock it in place. This increases the fulcrum of the operating platform 1 and improves its stability. This solves the problem that existing chimney outer wall 6 anti-corrosion construction operating platforms 1, which are designed for personnel to stand on, are often designed to abut against the outer wall of the construction platform through abutment wheels. Since the verticality of the outer wall 6 of the chimney is not maintained at 90 degrees and perpendicular to the ground, the operating platform 1 cannot maintain a vertical and stable state during construction and lifting, thus affecting the safety of personnel during construction.

[0038] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
