Description

Technical Field

[0001] This application belongs to the field of suspended platform technology, specifically relating to a suspended platform lifting control assembly. Background Technology

[0002] A suspended platform is a construction tool used for high-altitude operations in construction projects. The cantilever mechanism is erected on a building or structure, and the suspended platform is driven by a winch mechanism. It moves up and down along the facade of the building or structure via steel wire ropes and also serves as a working platform for operators.

[0003] In the use of existing suspended platforms, two operators are required to work on the platform; it is prohibited for a single person to work on the platform.

[0004] However, in the existing technology, a single operator can raise or lower the suspended platform by pressing the up or down button on the control box, which easily leads to situations where only one person is working.

[0005] In addition, when two operators are working on the suspended platform, if one operator finishes their work and the other is finishing up or tidying up their tools, i.e., the other operator is not ready to raise or lower, and the former presses the raise or lower button, the latter may become unstable without being prepared, posing a safety hazard. Utility Model Content

[0006] This application provides a suspended platform lifting control assembly, which aims to solve the safety hazards of the existing technology where a single person can control the lifting of the suspended platform.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0008] A suspended platform lifting control assembly is provided, comprising:

[0009] A control box is installed on the suspended platform; the control box is equipped with an up button and a down button, both of which are electrically connected to the winch; the up button and the down button are connected in parallel, and the up button and the down button are connected in series with a control bus;

[0010] A normally open control switch is connected to the suspended platform and to the control bus; the distance at which a single person can simultaneously touch the control box and the normally open control switch is the single-person operating distance; the installation distance between the normally open control switch and the control box is greater than the single-person operating distance.

[0011] When the normally open control switch is pressed, the control bus is energized; when the normally open control switch is stopped being pressed, the control bus is de-energized.

[0012] In one possible implementation, the normally open control switch is fixed to the top of the suspended basket railing by cable ties, or the normally open control switch is fixed to the top of the suspended basket railing by bolts and nuts.

[0013] In one possible implementation, when the normally open control switch is fixed to the suspended basket railing by bolts and nuts, a first connecting part is fixedly provided on the outer side wall of the normally open control switch, and a second connecting part is fixedly provided on the suspended basket railing.

[0014] The first connecting part and the second connecting part have through holes aligned with each other. Bolts can pass through the through holes on the first connecting part and the second connecting part and cooperate with nuts to fasten the normally open control switch.

[0015] In one possible implementation, when the normally open control switch is fixed to the basket railing with cable ties, two anti-rotation plates are connected to the basket. The two anti-rotation plates contact the outer and inner sides of the normally open control switch respectively, so as to limit the swing of the normally open control switch inward and outward when the cable ties are tightened.

[0016] In one possible implementation, when the width of the normally open control switch is less than the width of the top of the suspended basket railing, the bottoms of both anti-rotation plates are fixed to the top of the suspended basket railing.

[0017] When the width of the normally open control switch is greater than the width of the top of the suspended basket railing, the bottom of one of the anti-rotation plates is fixed to the top of the suspended basket railing, and the other anti-rotation plate is bent; the bent end of the other anti-rotation plate is fixed to the side of the railing.

[0018] In one possible implementation, the outer wall of the normally open control switch is fixed with insert plates at both ends of each anti-rotation plate, and the insert plates contact the ends of the anti-rotation plates to restrict the sliding of the normally open control switch between the two anti-rotation plates.

[0019] In one possible implementation, a sealing plate is fixedly installed on the outer side of the two insert plates on the same side of the normally open control switch, and a slot is formed between the sealing plate, the two insert plates and the side wall of the normally open control switch, and the anti-rotation plate is inserted into the slot.

[0020] In one possible implementation, a mounting plate is fixedly installed on the top of the control box, with one end of the mounting plate welded to the top of the suspended platform railing; a support plate is fixedly installed on the bottom of the control box, with one end of the support plate welded to the suspended platform railing.

[0021] In one possible implementation, the welding end of the mounting plate has a bent portion, and the welding end of the support plate also has a bent portion; wherein, before welding, the bent portion is hung on the railing of the basket.

[0022] In one possible implementation, a rib is fixed between the bottom of the support plate and the bend, and the rib is welded to the side of the hanging basket railing.

[0023] This application provides a suspended platform lifting control assembly. Compared with the prior art, by installing a normally open control switch on the suspended platform railing, the on / off state of the control bus can be controlled. When the normally open control switch is not pressed, it is in the open state, and the control bus is not energized. Even if the operator presses the up or down button, the suspended platform will not rise or fall, thus reducing safety hazards. When both operators are ready, one operator presses the normally open control switch to energize the control bus, and the other operator presses the up or down button to raise or lower the suspended platform. Through the above operation method, the suspended platform can be raised and lowered when both operators are ready, improving safety performance and reducing safety hazards.

[0036] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0037] Please refer to the following: Figures 1 to 11 The present application provides a description of a suspended platform lifting control assembly. This suspended platform lifting control assembly includes a control box 1 and a normally open control switch 2. The control box 1 is mounted on the suspended platform 3. The control box 1 has an up button 11 and a down button 12, both electrically connected to the winch. The up button 11 and the down button 12 are connected in parallel and share a common control bus. The control box 1 also has an emergency stop button 13. The circuit wiring of the emergency stop button 13 within the control box 1 is existing technology and will not be described further here.

[0038] Normally open control switch 2 is connected to the suspended platform 3 and to the control bus; the distance at which a single person can simultaneously touch the control box 1 and the normally open control switch 2 is the single-person operating distance; the installation distance between the normally open control switch 2 and the control box 1 is greater than the single-person operating distance.

[0039] When the normally open control switch 2 is pressed, the control bus is energized; when the normally open control switch 2 is stopped being pressed, the control bus is de-energized.

[0040] This application provides a lifting control assembly for a suspended platform 3. Compared with the prior art, by setting a normally open control switch 2 on the railing 31 of the suspended platform 3, the on / off state of the control bus can be controlled. When the normally open control switch 2 is not pressed, it is in the open state, and the control bus is not energized. Even if the operator presses the up button 11 or the down button 12, the suspended platform 3 will not rise or fall, thus reducing safety hazards. When both operators are ready, one operator presses the normally open control switch 2 to energize the control bus, and the other operator presses the up button 11 or the down button 12 to raise or lower the suspended platform 3. Through the above operation method, the suspended platform 3 can be raised and lowered when both operators are ready, improving safety performance and reducing safety hazards.

[0041] It should be noted that the solution in this application is applied to the suspended platform 3 for two-person operation, and is not applicable to the suspended platform 3 for single-person operation; the control bus is a live wire, and the control bus is connected to the normally open control switch 2, and the on and off of the control bus is controlled by the normally open control switch 2.

[0042] When the normally open control switch 2 is pressed, the control bus forms a path at the position of the normally open control switch 2; when the up button 11 or the down button 12 is pressed, the suspended basket 3 can rise or fall.

[0043] When the normally open control switch 2 is stopped, it resets and the control bus is disconnected at the position of the normally open control switch 2. At this time, no matter whether the up button 11 or the down button 12 is pressed, no power is supplied and the suspended platform 3 will not rise or fall.

[0044] The control circuit of control box 1, the working principle of normally open control switch 2, and other mechanisms on the suspended platform 3 are all existing technologies and will not be described in detail here.

[0045] In some embodiments, such as Figures 1 to 11 As shown, the normally open control switch 2 is fixed to the top of the railing 31 of the suspended basket 3 by cable ties 4, or the normally open control switch 2 is fixed to the top of the railing 31 of the suspended basket 3 by bolts and nuts.

[0046] For example, such as Figures 1 to 11 As shown, when the normally open control switch 2 is fixed to the railing 31 of the suspended basket 3 by bolts and nuts, a first connecting part 21 is fixedly provided on the outer wall of the normally open control switch 2, and a second connecting part 22 is fixedly provided on the railing 31 of the suspended basket 3; wherein, the first connecting part 21 and the second connecting part 22 have through holes aligned with each other, and bolts can pass through the through holes on the first connecting part 21 and the second connecting part 22 and cooperate with nuts to fasten the normally open control switch 2.

[0047] A first connecting part 21 is fixedly installed on the outer wall of the normally open control switch 2, and a second connecting part 22 is installed on the railing 31 of the suspended basket 3. The first connecting part 21 and the second connecting part 22 have through holes that are aligned with each other. When installing the normally open control switch 2, the normally open control switch 2 is placed at the top of the railing 31 of the suspended basket 3, and the through holes on the first connecting part 21 are aligned with the through holes on the second connecting part 22. At this time, the threaded end of the bolt passes through the first connecting part 21 and the second connecting part 22, and the threaded end protrudes from the second connecting part 22 and engages with the nut. After the bolt and nut are tightened, the normally open control switch 2 can be fixed on the railing 31 of the suspended basket 3.

[0048] The installation process is as follows: After the normally open control switch 2 is wired, place the normally open control switch 2 in the installation position and align the through hole on the first connecting part 21 with the through hole on the second connecting part 22; then pass the bolt through the first connecting part 21 and the second connecting part 22, and finally fix the normally open control switch 2 to the railing 31 of the hanging basket 3 by using the nut and the bolt.

[0049] For example, such as Figures 1 to 11 As shown, when the normally open control switch 2 is fixed to the railing 31 of the suspended basket 3 by the cable tie 4, two anti-rotation plates 5 are connected to the suspended basket 3. The two anti-rotation plates 5 contact the outer and inner sides of the normally open control switch 2 respectively, so as to limit the swing of the normally open control switch 2 in the inner and outer directions when the cable tie 4 is tightened.

[0050] During the process of fixing the normally open control switch 2 with cable ties 4, the two anti-rotation plates 5 contact the inner and outer sides of the normally open control switch 2 respectively, which can limit the normally open control switch 2 in the inner and outer directions and restrict the swing of the normally open control switch 2 in the inner and outer directions.

[0051] The inner side of the normally open control switch 2 refers to the direction facing the standing area of ​​the suspended basket 3, and the outer side of the normally open control switch 2 refers to the direction away from the standing area of ​​the suspended basket 3. When fixing the normally open control switch 2 with the cable tie 4, the cable tie 4 passes around the normally open control switch 2 and the top position of the railing 31 of the suspended basket 3, and then the cable tie 4 is tightened to fix the normally open control switch 2 to the railing 31 of the suspended basket 3.

[0052] Since the direction in which the cable tie 4 passes around the normally open control switch 2 is the inside and outside direction of the normally open control switch 2, the anti-rotation plates 5 on the inside and outside of the normally open control switch 2 can limit the inside and outside swing of the normally open control switch 2 during the tightening process of the cable tie 4.

[0053] In some embodiments, such as Figures 1 to 11As shown, when the width of the normally open control switch 2 is less than the width of the top of the railing 31 of the suspended basket 3, the bottom of both anti-rotation plates 5 are fixed to the top of the railing 31 of the suspended basket 3; when the width of the normally open control switch 2 is greater than the width of the top of the railing 31 of the suspended basket 3, the bottom of one anti-rotation plate 5 is fixed to the top of the railing 31 of the suspended basket 3, and the other anti-rotation plate 5 is bent; the bent end of the other anti-rotation plate 5 is fixed to the side of the railing 31.

[0054] It should be noted that the anti-rotation plate 5 at the top of the railing 31 of the suspended basket 3 has different models. For normally open control switches 2 of different widths, the appropriate model of anti-rotation plate 5 needs to be selected.

[0055] Once the model of the normally open control switch 2 is selected, the model of the anti-rotation plate 5 is also determined. Then, the anti-rotation plate 5 is fixed at the top of the railing 31. When the normally open control switch 2 is placed between the two anti-rotation plates 5, the inner and outer sides of the normally open control switch 2 can contact the corresponding anti-rotation plates 5 respectively.

[0056] If the width of the normally open control switch 2 exceeds the width of the top of the railing 31 of the suspended basket 3, the bottom of one of the anti-rotation plates 5 is fixed to one side of the top of the railing 31, and the outer side of the anti-rotation plate 5 is on the same plane as the outer side of the railing 31; the other anti-rotation plate 5 contacts the other side of the normally open control switch 2, and the bottom of the other anti-rotation plate 5 is bent and fixedly connected to the railing 31; with the above arrangement, the space between the two anti-rotation plates 5 can accommodate the normally open control switch 2.

[0057] In some embodiments, such as Figures 1 to 11 As shown, the outer wall of the normally open control switch 2 is fixed with insert plates 6 at both ends of each anti-rotation plate 5. The insert plates 6 contact the ends of the anti-rotation plates 5 to restrict the sliding of the normally open control switch 2 between the two anti-rotation plates 5.

[0058] By installing insert plates 6 at both ends of each anti-rotation plate 5 on the normally open control switch 2, the sliding of the normally open control switch 2 along the length direction of the railing 31 of the hanging basket 3 can be restricted through the cooperation of the two insert plates 6 and the anti-rotation plate 5, thereby improving the stability of the normally open control switch 2 after installation.

[0059] To strengthen the connection between the normally open control switch 2 and the railing 31 of the hanging basket 3, a sealing plate 61 is fixedly installed on the outside of the two insert plates 6 on the same side of the normally open control switch 2, forming a U-shaped structure between the sealing plate 61 and the two insert plates 6; a slot 62 is formed between the sealing plate 61, the two insert plates 6 and the side wall of the normally open control switch 2, and the anti-rotation plate 5 is inserted into the slot 62.

[0060] After the anti-rotation plate 5 is inserted into the slot 62, it can restrict the sliding of the normally open control switch 2 in the horizontal direction. After being tightened by the cable tie 4, it can restrict the sliding of the normally open control switch 2 in the vertical direction.

[0061] Therefore, the above-mentioned settings in this application can limit the sliding of the normally open control switch 2 in the horizontal and vertical directions, thereby improving the stability of the normally open control switch 2.

[0062] In some embodiments, such as Figures 1 to 11 As shown, a mounting plate 14 is fixedly installed on the top of the control box 1, and one end of the mounting plate 14 is welded to the top of the railing 31 of the suspended basket 3; a support plate 15 is fixedly installed at the bottom of the control box 1, and one end of the support plate 15 is welded to the railing 31 of the suspended basket 3.

[0063] By setting mounting plate 14 and support plate 15 at the top and bottom of control box 1 respectively, and welding mounting plate 14 and support plate 15 to railing 31 of suspended basket 3, the position of control box 1 can be fixed, so that control box 1 is relatively fixed to railing 31 of suspended basket 3.

[0064] In this application, the control box 1 is located outside the railing 31 of the suspended basket 3. Therefore, the control box 1 does not occupy the space enclosed by the railing 31 of the suspended basket 3, that is, the control box 1 does not occupy the space of the standing area. When the operator needs to operate the up button 11 or the down button 12, one of the operator's hands is on the railing 31, and the other hand of the operator operates the up button 11 or the down button 12 on the control box 1.

[0065] In some embodiments, such as Figures 1 to 11 As shown, the welding end of the mounting plate 14 has a bent portion 16, and the welding end of the support plate 15 also has a bent portion 16; wherein, before welding, the bent portion 16 is hung on the railing 31 of the hanging basket 3.

[0066] With the above-described configuration of this application, the bent portion 16 of the mounting plate 14 is hung at the top of the railing 31, and the bent portion 16 of the support plate 15 is hung at the middle of the railing 31, which can initially position the control box 1 and place the control box 1 on the railing 31; then the mounting plate 14 and the support plate 15 are welded to the railing 31 by welding equipment.

[0067] The connection between the mounting plate 14 and the control box 1 can be either bolted or welded; the connection between the support plate 15 and the control box 1 can also be either bolted or welded.

[0068] To improve the support strength of the support plate 15, a rib plate 17 is fixed between the bottom of the support plate 15 and the bending part 16. The rib plate 17 is welded to the side of the railing 31 of the hanging basket 3. There can be multiple support rib plates 17 on the support plate 15. By setting the rib plate 17 between the support plate 15 and the railing 31, the support strength of the support plate 15 can be improved.

[0069] Working principle: When two operators are needed to construct the exterior wall of a building, both operators stand on the suspended platform 3 and place the relevant construction tools on it. Then, one operator presses the normally open control switch 2, and the other operator presses the rise button 11, which raises the suspended platform 3. After the suspended platform 3 reaches the designated position, releasing the rise button 11 and the normally open control switch 2 will stop the suspended platform 3 at the designated position, making it convenient for the operators to construct the exterior wall of the building. When construction is required at different heights, the above process can be repeated to adjust the height of the suspended platform 3.

[0070] After both operators have finished their work, one operator presses the normally open control switch 2 and the other operator presses the descent button 12, which will cause the suspended platform 3 to descend and eventually land on the ground.

[0071] The installation process of the normally open control switch 2 by fixing it with cable ties 4 is as follows: the slot 62 of the normally open control switch 2 is inserted into the anti-rotation plate 5 at the top of the railing 31 to initially position the normally open control switch 2; then, the cable ties 4 are passed around the normally open control switch 2 and the crossbar at the top of the railing 31, and the cable ties 4 are tightened to fix the normally open control switch 2 to the railing 31 of the suspended basket 3; through the above settings, the stability between the normally open control switch 2 and the railing 31 of the suspended basket 3 can be improved.

[0072] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
