Description

Technical Field

[0001] This application relates to the field of construction equipment technology, and in particular to a suspended platform device for chimney interior wall construction. Background Technology

[0002] Suspended platforms are common equipment in the construction industry, used to carry people and goods, enabling high-altitude maintenance and demolition operations. Chimneys, on the other hand, are important facilities in industrial production, and many were built in the last century.

[0003] As chimneys age and industrial technology upgrades, some develop problems requiring repair, while others face demolition and are revitalized as parks or tourist attractions. The repair and removal of the inner walls and inner layers of chimneys typically require the use of suspended platforms. However, the following problems exist in the use of suspended platforms:

[0004] 1. Typically, the lower diameter of a chimney is larger than the upper diameter, while the suspended platform descends vertically from the top of the chimney. As the platform descends, the work platform cannot get close enough to the inner wall of the chimney to perform operations.

[0005] 2. The maintenance and dismantling work is often carried out from top to bottom in a circular segment. Moving the suspended platform horizontally along the chimney is very troublesome. It is necessary to first lower the suspended platform to the ground, then dismantle and move the suspension device and reinstall it, and then raise the suspended platform to the designated working height. This results in low construction efficiency and the inability to guarantee construction quality. In addition, the risk of dismantling and reinstalling the suspension device at high altitude is high. Moreover, during the process of lowering the suspended platform to the ground, moving it, and then raising and lowering it, the remaining structure that has been dismantled halfway in the circular segment is at risk of instability and falling, causing injury. Utility Model Content

[0006] The purpose of this application is to address the problems of inconvenience, low efficiency, and low safety associated with using suspended platforms for chimney inner wall construction in the prior art. Therefore, this application provides a suspended platform device for chimney inner wall construction. A suspension mechanism allows the main body of the suspended platform to move and rise and fall along the circumference of the chimney. A limiting mechanism and an adjusting mechanism work together to ensure the main body of the suspended platform is close to the inner wall of the chimney, thereby facilitating construction and improving efficiency and safety.

[0007] This application provides a suspended platform device for chimney inner wall construction, comprising:

[0008] A suspension mechanism is connected to a first drive mechanism, and the suspension mechanism includes a clamping part for clamping the top of the chimney and sliding along the circumference of the chimney under the drive of the first drive mechanism;

[0009] The main body of the suspended platform is connected to a second drive mechanism. The main body of the suspended platform is suspended below the suspension mechanism and located inside the chimney. Under the drive of the second drive mechanism, it can be raised and lowered relative to the suspension mechanism.

[0010] A limiting mechanism includes a limiting member, which is disposed along the height direction of the chimney and located inside the chimney, and can move synchronously with the suspension mechanism along the circumference of the chimney; and,

[0011] An adjustment mechanism includes an adjustment member, one end of which is connected to the limiting member and can slide along the limiting member, and the other end is connected to the suspended basket body. The adjustment member is used to adjust the distance between the suspended basket body and the limiting member so that a preset distance is maintained between the suspended basket body and the inner wall of the chimney.

[0012] By adopting the above technical solution, the main body of the suspended platform is suspended by a suspension mechanism. Driven by a second drive mechanism, the main body of the suspended platform can be raised and lowered. Furthermore, driven by a first drive mechanism, the suspension mechanism can simultaneously move the main body of the suspended platform along the circumference of the chimney. This achieves movement of the main body of the suspended platform along both the circumference and height of the chimney, enabling construction personnel to perform segmented, circular construction of the chimney's inner wall from top to bottom within the suspended platform. This improves construction convenience, efficiency, and safety. Moreover, during construction, the main body of the suspended platform can be moved circumferentially at any time via the suspension mechanism without needing to be lowered to the ground for adjustments, further enhancing construction convenience and efficiency. Simultaneously, through the cooperation of limiting and adjusting mechanisms, the main body of the suspended platform maintains a preset distance from the inner wall of the chimney throughout the construction process, ensuring that construction personnel remain within the construction radius, thereby further improving construction convenience and safety.

[0013] In some embodiments, the limiting mechanism further includes a connector, which is used to fix the suspension mechanism to a corresponding position at the bottom of the inner wall of the chimney or a corresponding position on the ground, depending on the position of the suspension mechanism in the circumferential direction of the chimney.

[0014] The limiting component is a rope, with one end connected to the suspension mechanism and the other end connected to the connecting component. By changing the connecting component connected to different positions, the limiting component can move synchronously with the main body of the suspended basket along the circumference of the chimney.

[0015] Using the above technical solution, the limiting component is connected to the suspension mechanism at one end, so that the end can move synchronously with the suspension mechanism along the circumference of the chimney. The other end is connected to the connecting components located at different positions at the bottom of the chimney, so that the end can be fixed to correspond to the movement of the suspension mechanism. Thus, the entire limiting component can move synchronously with the suspension mechanism along the circumference of the chimney, and the operation is convenient.

[0016] In some embodiments, the limiting mechanism further includes a turnbuckle, which connects the limiting member and the connecting member and is used to tension the limiting member.

[0017] In some embodiments, the adjusting mechanism further includes a first winch disposed on the suspended platform body;

[0018] The adjusting component is a rope, and the other end of the adjusting component is connected to the first winch. The rope is wound up and down by the first winch to adjust the distance between the suspended basket body and the limiting component.

[0019] In some embodiments, the adjusting mechanism further includes a shackle, and one end of the adjusting member is connected to the limiting member via the shackle.

[0020] In some embodiments, two clamping parts are symmetrically arranged and are respectively connected to the two ends of the basket body through suspension members, and the suspension members are connected to the second drive mechanism;

[0021] The clamping part includes a bracket, on which a first traveling wheel, a second traveling wheel and a third traveling wheel are provided. The first traveling wheel is used to contact the top surface of the chimney, and the second traveling wheel and the third traveling wheel are arranged opposite to each other and are used to contact the inner and outer walls of the chimney respectively.

[0022] Both supports are connected to the first drive mechanism via ropes.

[0023] In some embodiments, the support includes a first rod, a second rod, a third rod, and a diagonal brace, wherein the second rod and the third rod are spaced apart and respectively perpendicularly disposed on the first rod, and the diagonal brace is disposed between the first rod and the third rod;

[0024] The first walking wheel is mounted on the first pole and is located between the second pole and the third pole;

[0025] The second traveling wheel is mounted on the second rod, and the third traveling wheel is mounted on the third rod;

[0026] The suspension point of the main body of the suspended basket is located on the first pole and close to the diagonal brace.

[0027] In some embodiments, the limiting member is arranged parallel to the inner wall of the chimney.

[0028] Other features and corresponding beneficial effects of this application will be described in the latter part of the specification, and it should be understood that at least some of the beneficial effects will become obvious from the description in this application.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] It should be noted that the inner wall of a chimney usually has multiple layers, such as insulation layers and decorative layers. Repair and dismantling work on the inner wall of a chimney refers to repairing or dismantling different layers of the inner wall of the chimney, but without damaging the overall structure of the chimney.

[0042] Typically, this type of construction requires the use of suspended platforms to assist workers.

[0043] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating the usage status of this application.

[0044] This application provides a suspended platform device for chimney inner wall construction, including a suspension structure and a suspended platform body 2.

[0045] The suspension mechanism 1 is located at the top of the chimney, providing a base for the installation of the basket body 2. Preferably, the suspension mechanism 1 includes a clamping part 12 for clamping onto the top of the chimney.

[0046] The main body 2 of the suspended platform is suspended below the suspension mechanism 1 and located inside the chimney. The main body 2 of the suspended platform is connected to a second drive mechanism, and can be raised and lowered relative to the suspension mechanism 1 under the drive of the second drive mechanism. That is, the main body 2 of the suspended platform can be raised and lowered along the inner wall of the chimney under the drive of the second drive mechanism, so that the construction personnel inside the main body 2 can carry out construction on the inner wall of the chimney from top to bottom.

[0047] It should be noted that, in order to ensure the safety of chimney construction, the maintenance and dismantling of the inner wall of the chimney is carried out not only from top to bottom, but also in a circular manner, that is, construction is carried out layer by layer downward along the height of the chimney.

[0048] In conventional construction, the suspended platform needs to be lowered to the ground first, then the suspension mechanism 1 on the chimney needs to be dismantled, moved circumferentially, and reinstalled before the platform is raised to the designated working height. This results in low construction efficiency and poses a high risk of dismantling and reinstalling the suspension mechanism 1 at high altitude. In addition, during the process of lowering the platform to the ground, moving it, and then raising and lowering it again, the remaining structure in the ring section that has been dismantled halfway poses a risk of instability and falling, causing injury.

[0049] Therefore, the suspension mechanism 1 of this application is connected to the first drive mechanism 11, and can slide along the circumference of the chimney under the drive of the first drive mechanism 11. That is, after being installed at the top of the chimney once, it can slide along the circumference of the chimney at any time during the construction process without dismantling and re-moving or reinstalling. It can keep up with the construction progress in real time and move along the same height of the corresponding construction ring segment, which greatly improves the convenience, efficiency and safety of construction.

[0050] In other words, this suspended platform device enables continuous high-altitude operations through aerial translation, thereby improving work efficiency; and by avoiding frequent landings, repositioning, and re-ascending of the suspended platform, it avoids the risk of being struck by falling objects from heights, thus improving safety.

[0051] It should also be noted that the interior of a chimney is usually larger in diameter at the bottom and smaller in diameter at the top. The suspended platform gradually descends from the top of the chimney as construction progresses and will gradually move away from the inner wall of the chimney without intervention. This causes the construction personnel inside the main body 2 of the suspended platform to be out of the construction radius, making construction inconvenient and increasing the construction risk.

[0052] Therefore, in one embodiment, the suspended platform device further includes a limiting mechanism and an adjusting mechanism.

[0053] The limiting mechanism includes a limiting member 31, which is arranged along the height direction of the chimney and located inside the chimney, and can move synchronously with the suspension mechanism 1 along the circumference of the chimney.

[0054] The adjustment mechanism includes an adjustment component 41. One end of the adjustment component 41 is connected to the limiting component 31 and can slide along the limiting component 31. The other end is connected to the main body 2 of the suspended platform. The adjustment component 41 is used to adjust the distance between the main body 2 of the suspended platform and the limiting component 31 so that the main body 2 of the suspended platform and the inner wall of the chimney maintain a preset distance, so that the construction personnel are always within the construction radius, thereby further improving the convenience and safety of construction.

[0055] In other words, this suspended platform device, through the cooperation of the limiting mechanism and the adjusting mechanism, enables the main body 2 of the suspended platform to be stably and reliably close to the chimney wall, thereby ensuring the quality of maintenance and construction, and improving the convenience and safety of construction.

[0056] In one embodiment, the limiting mechanism further includes a connector for fixing the suspension mechanism 1 to a corresponding position at the bottom of the inner wall of the chimney or a corresponding position on the ground, depending on the position of the suspension mechanism 1 in the circumferential direction of the chimney.

[0057] In one specific embodiment, the limiting member 31 is a rope, such as a steel wire rope.

[0058] One end of the limiting member 31 is connected to the suspension mechanism 1, meaning that this end can move synchronously with the suspension mechanism 1 along the circumference of the chimney.

[0059] The other end of the limiting member 31 is connected to the connecting member. By replacing the connecting member at different positions, the limiting member 31 can move synchronously with the main body 2 of the suspended basket along the circumference of the chimney. That is, this end can be fixed to correspond to the movement of the suspension mechanism 1, so that the entire limiting member 31 can move synchronously with the suspension mechanism 1 along the circumference of the chimney. Moreover, it is easy to operate.

[0060] Preferably, the connector is an anchor bolt, which provides a reliable connection, is low in cost, and is easy to install.

[0061] Before construction, the locations of all connectors that need to be installed during construction can be determined by calculation, and the connectors can be installed one by one. During construction, as the suspension mechanism 1 moves synchronously, the limiting component 31 is replaced with the corresponding connector, thereby enabling the limiting component 31 to move synchronously with the main body of the suspended basket 2 along the circumference of the chimney.

[0062] Understandably, during the adjustment process, the limit member 31 can be disconnected from the adjusting member 41 to avoid interference.

[0063] In one embodiment, the limiting mechanism further includes a turnbuckle, which connects the limiting member 31 and the connecting member, and is used to tension the limiting member 31, that is, to keep the limiting member 31 taut, thereby facilitating the connection of the adjusting member 41, and controlling the distance between the suspended basket body 2 and the limiting member 31 through the adjusting member 41.

[0064] Furthermore, the turnbuckle is positioned between the connector and the limiting member 31, that is, near the bottom of the chimney, which makes it easy for construction workers to adjust the turnbuckle to tighten the limiting member 31.

[0065] In one embodiment, the limiting member 31 is arranged parallel to the inner wall of the chimney, so that the adjusting member 41 can be adjusted to a constant length, which is convenient for construction personnel to operate.

[0066] In one specific embodiment, the adjustment mechanism further includes a first winch, which is mounted on the main body 2 of the suspended platform.

[0067] The adjusting component 41 is a rope, such as a steel wire rope. The other end of the adjusting component 41 is connected to the first winch, and the rope is wound up and down by the first winch to adjust the distance between the suspended basket body 2 and the limiting component 31. Since the first winch is set on the suspended basket body 2, it is convenient for construction personnel inside the suspended basket body 2 to make adjustments according to construction needs, making the operation convenient.

[0068] In one specific embodiment, the adjustment mechanism further includes a shackle, one end of the adjustment member 41 is connected to the limiting member 31 through the shackle, that is, the adjustment member 41 is fixed with the shackle, and the shackle is sleeved on the limiting member 31, so as to facilitate the adjustment member 41 to slide along the limiting member 31, and the connection is reliable.

[0069] In other alternative embodiments, the adjusting member 41 is a rod with its two ends connected to the limiting member 31 and the main body 2 of the suspended platform, respectively. The rod with a fixed length ensures that the distance between the main body 2 of the suspended platform and the limiting member 31 is constant, thereby ensuring construction.

[0070] Please see Figure 2 , Figure 2 for Figure 1 A top-down view.

[0071] In one embodiment, two clamping parts 12 are symmetrically arranged, which can improve the stability of the suspension mechanism moving around the chimney, thereby improving the stability of the basket body 2 moving around the chimney.

[0072] The two clamping parts 12 are connected to both ends of the suspended basket body 2 through suspension components, which can also improve the suspension stability of the suspended basket body 2.

[0073] The suspension component is connected to the second drive mechanism, thereby enabling the lifting and lowering of the main body 2 of the suspended basket.

[0074] In one embodiment, the two clamping parts 12 are connected to the first drive mechanism 11, such as a winch, via a translation member 13, such as a wire rope. The suspension mechanism 1 is moved circumferentially by the first drive mechanism 11 through the retraction and extension of the translation member 13.

[0075] In one specific embodiment, the first drive mechanism 11 includes two winches, which are fixed to the chimney wall 5 by chemical anchors, anchor plates and bolts.

[0076] There are two translation components 13. One of the translation components 13 is arranged clockwise along the chimney, and one end of it is fixed to the two clamping parts 12, and the other end is fixed to one of the two winches. The other translation component 13 is arranged counterclockwise along the chimney, and one end of it is fixed to the two clamping parts 12, and the other end is fixed to the other of the two winches.

[0077] When the two clamping parts 12 move circumferentially, two winches are needed to work together to control the movement of the suspension mechanism 1 along the chimney circumferentially.

[0078] Please see Figure 3 , Figure 3 This is a schematic diagram of the clamping part 12 in this application.

[0079] In one embodiment, the clamping part 12 includes a support.

[0080] The support frame is equipped with a first traveling wheel 125, a second traveling wheel 126, and a third traveling wheel 127. The first traveling wheel 125 is used to contact the top surface of the chimney, while the second traveling wheel 126 and the third traveling wheel 127 are arranged opposite to each other and are used to contact the inner and outer walls of the chimney, respectively, thereby enabling the clamping part 12 to move stably along the circumference of the chimney.

[0081] Furthermore, both supports are connected to the first drive mechanism 11 via ropes, namely the translation component 13.

[0082] In one specific embodiment, the support includes a first rod 121, a second rod 122, a third rod 123, and a diagonal brace 124. The second rod 122 and the third rod 123 are spaced apart and respectively perpendicularly disposed on the first rod 121, so that the support can straddle the top of the chimney. The diagonal brace 124 is disposed between the first rod 121 and the third rod 123, thereby enhancing the strength between the two.

[0083] The first traveling wheel 125 is mounted on the first rod 121 and is located between the second rod 122 and the third rod 123.

[0084] The second traveling wheel 126 is mounted on the second rod 122, and the third traveling wheel 127 is mounted on the third rod 123.

[0085] The suspension point of the main body 2 of the suspended platform, i.e., the position indicated by a, is set on the first rod 121 and close to the diagonal brace 124.

[0086] The construction steps for using this suspended platform device are as follows:

[0087] 1. The suspension mechanism 1 and the first drive mechanism 11 are manually carried to the top of the chimney wall 5 via the well wall ladder. Then, the two clamping parts 12 of the suspension mechanism 1 are installed in sequence and fixed to the chimney wall 5 by the three traveling wheels. The first drive mechanism 11 is then installed. If the chimney wall 5 is not flat, it must be repaired in advance or a steel plate track matching the traveling wheels must be installed in advance.

[0088] 2. Anchor bolts are installed on the inner side of the bottom of the chimney wall 5, and limiters 31 and turnbuckles are installed and connected to the bottom of the suspension mechanism 1.

[0089] 3. The adjusting component 41 and the first winch are installed on the main body 2 of the suspended platform.

[0090] 4. Continue to install the working wire rope (suspension component) of the suspended platform on the top of the main body 2.

[0091] 5. Tighten the limiting piece 31 by using turnbuckles.

[0092] 6. The main body 2 of the suspended basket carries people to the top of the chimney, and the adjusting component 41 is connected to the limiting component 31 through the shackle.

[0093] 7. As the main body 2 of the suspended platform descends, the tension adjustment component 41 of the first winch is used to ensure that the main body 2 of the suspended platform always maintains a certain distance from the inner wall of the chimney.

[0094] 8. The first drive mechanism 11 is manually controlled at the top of the chimney. By retracting and extending the two translation components, the two clamping parts 12 are moved circumferentially along the chimney wall 5, thereby driving the main body 2 of the suspended basket to move circumferentially.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
