Description

Technical Field

[0001] This invention relates to construction tools, specifically a mobile cantilevered operating platform. Background Technology

[0002] Cantilevered operating platforms are typically used to provide a working platform when constructing on the exterior of a building. Currently, cantilevered operating platforms are generally fixed and the extension distance of the platform cannot be adjusted, which limits the operating range. If some parts of the building exterior protrude significantly, the difficulty of construction for workers increases, and construction may even become impossible.

[0003] Although there are movable cantilevered operating platforms in the existing technology, their movement is limited to lateral movement and cannot overcome the problem of excessive protrusion of the building exterior by moving forward and backward.

[0004] In addition, there is currently a problem that the space between the cantilever and the operating platform is too small, making it difficult for staff to pass through.

[0005] This shows that the current cantilevered operating platform still has many shortcomings and is poorly adaptable to building construction. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a mobile cantilevered operating platform that allows workers to conveniently operate on protruding parts of the building's exterior. It also provides elevation while facilitating worker access to and from the platform, making it easier for workers to move between operating areas at the same height. Furthermore, it offers good support stability while allowing workers to easily move to another operating position.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A mobile cantilevered operating platform, including

[0009] Counterweight frame;

[0010] The top rod is telescopically mounted on the top of the counterweight frame, and the top of the top rod is equipped with rollers;

[0011] The pulleys are located at the bottom of the counterweight frame to support the counterweight frame and to facilitate its movement.

[0012] The operating frame is laterally telescopic and mounted on the side of the counterweight frame;

[0013] The operating frame includes two support rods and four connecting rods;

[0014] The four connecting rods are arranged in two rows, and the connecting rods in the same row are connected by support rods;

[0015] All connecting rods can be telescopically connected to the side of the counterweight frame;

[0016] The lower row of connecting rods is equipped with an operating platform and a folding step on the operating platform.

[0017] As a further improvement of the present invention, a first sling is provided on the connecting rod in the upper row, and the first sling is fixedly connected to the folding step; and when the connecting rod extends and the first sling is pulled, the folding step unfolds.

[0018] As a further improvement of the present invention

[0019] The number of steps is two, namely a high-order step and a low-order step;

[0020] The folding steps have high-level horizontal plates, high-level vertical plates, low-level horizontal plates, and low-level vertical plates.

[0021] The higher-order horizontal plate and the higher-order vertical plate are fixedly connected and form a 90-degree outward convex angle.

[0022] The higher-order longitudinal plate and the lower-order transverse plate are fixedly connected and form a 90-degree concave angle.

[0023] The low-order horizontal plate and the low-order vertical plate are hinged together;

[0024] The lower-level longitudinal plate is also hinged to the connecting rod or operating platform on the other side corresponding to the lower-level transverse plate; the first sling is fixedly connected to the side of the higher-level transverse plate away from the higher-level longitudinal plate at one end of the folding step.

[0025] As a further improvement of the present invention, the counterweight frame is provided with a fixed pulley, and the lower horizontal plate is fixedly connected with a second sling. The other end of the second sling also passes around the fixed pulley and is fixedly connected to one side of the higher horizontal plate corresponding to the higher vertical plate. The second sling, together with the first sling, keeps the higher horizontal plate and the lower horizontal plate horizontally set.

[0026] As a further improvement of the present invention, a telescopic rod is also provided at the end of the connecting rod in the upper row away from the counterweight frame, and a driving component for driving the telescopic rod to extend and retract is also provided on the connecting rod; one end of the first sling is fixedly connected to the high-level horizontal plate, and the other end is fixedly connected to the telescopic rod.

[0027] As a further improvement of the present invention, the driving component is sleeved on the connecting rod and drives the telescopic rod to extend and retract by rotating it; the telescopic rod and the driving component are threadedly connected, and the telescopic rod is driven to extend and retract by the threaded engagement.

[0028] The beneficial effects of the present invention

[0029] 1. The counterweight frame can be tightened against the top of the floor by extending and retracting the top rod, and supported by the ground by pulleys. The rollers on the top rod and the pulleys at the bottom can be easily moved to another operating position while being tightened.

[0030] 2. Folding steps are also installed on the operating platform. When unfolded, these steps form footrests, allowing staff to elevate themselves and operate from higher positions. The folding and stowing of the steps allows the operating platform to be positioned lower, providing sufficient space between the platform and the cantilever for staff to pass through. Once staff reach the platform, the steps can be unfolded, allowing them to stand on them and operate the equipment, thus overcoming height limitations and making it easier for users to reach the operating platform.

[0031] 3. The connecting rod is telescopic, allowing the operating platform to be extended and retracted, thus enabling operation on protruding parts of the building's exterior. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0038] Reference Figure 1-4 As shown, a mobile cantilevered operating platform includes...

[0039] Counterweight frame 1;

[0040] The top rod 2 is telescopically mounted on the top of the counterweight frame 1, and the top of the top rod 2 is equipped with a roller 21;

[0041] Pulley 3 is located at the bottom of counterweight frame 1 to support counterweight frame 1 and to facilitate the movement of counterweight frame 1;

[0042] The operating frame 4 is laterally telescopically mounted on the side of the counterweight frame 1;

[0043] The operating frame 4 includes two support rods and four connecting rods 41;

[0044] The four connecting rods 41 are arranged in two rows, and the connecting rods 41 in the same row are connected by support rods;

[0045] All connecting rods 41 can be telescopically connected to the side of the counterweight frame 1;

[0046] The lower row of connecting rods 41 is provided with an operating platform 42 and a folding step 5 on the operating platform 42.

[0047] In this design, the counterweight frame 1 is secured to the top of the floor via the top rod 2 and supported by pulleys 3. Ideally, the pulleys 3 should have a self-locking function or a locking mechanism, allowing the counterweight frame 1 to lock when it reaches a designated position, preventing further movement. When movement is needed, the pulleys 3 can be unlocked, allowing the counterweight frame 1 to be pushed, simultaneously moving the operating frame 4. The top rod 2 can be threaded into the counterweight frame 1. During adjustment, rotating the top rod 2 extends it to secure it against the floor ceiling. The rollers 21 on the top rod 2 engage with the ceiling for easier movement.

[0048] In this design, a folding step 5 is also installed on the operating platform 42. When unfolded, the folding step 5 forms a footrest, allowing staff to elevate themselves and operate from higher positions. The folding and stowing of the folding step 5 allows the operating platform 42 to be positioned lower, providing sufficient space between the platform and the cantilever for staff to pass through. After reaching the operating platform 42, the folding step 5 can be unfolded, allowing staff to stand on the step to operate, thus overcoming height limitations and making it easier for users to reach the operating platform 42.

[0049] The counterweight frame 1 in this design can be installed using a telescopic structure (as shown in the figure), providing lifting capabilities. The telescopic structure allows for longitudinal extension and retraction of the counterweight frame 1, and it is secured with bolts. Additionally, it can also include diagonal braces, which also employ a telescopic structure. These braces support the connecting rod 41, maintaining its strength and thus enhancing the strength of the operating platform 42. The diagonal braces can also be hinged to the connecting rod 41, allowing for relative rotation.

[0050] The operating frame 4, as shown in the figure, requires at least four connecting rods 41 and two support rods. All four connecting rods 41 are telescopically connected to the operating frame 4, meaning that the connecting rods 41 extend and retract laterally on the counterweight frame 1. The four connecting rods 41 can form two rows, upper and lower, and a barrier can be connected between the upper and lower rows to provide protection.

[0051] During use, after entering the operating platform 42, staff can work at higher positions using the folding steps 5. After completing the operation, staff can move to another workstation with the assistance of another staff member, thus avoiding the need to enter and exit and reducing the safety hazard of collisions.

[0052] The extension and retraction of the connecting rod 41 allows the operating platform 42 to move, thereby meeting more usage needs, such as operating on more prominent positions on the exterior of the building.

[0053] In a further configuration, a first sling 6 is provided on the connecting rod 41 in the upper row, which is fixedly connected to the folding step 5; and when the connecting rod 41 extends and the first sling 6 is pulled, the folding step 5 unfolds.

[0054] When the first sling 6 extends or retracts the connecting rod 41, and the upper connecting rod 41 extends to a greater extent than the lower connecting rod 41, the first sling 6 can pull the folding step 5, causing the folding step 5 to move upward and outward, thus unfolding the folding step 5. After unfolding, the folding step 5 can be stepped on by the staff. This solution can unfold the step while adjusting the connecting rod 41 as needed, allowing the staff to be elevated.

[0055] Specifically, the number of steps is two, namely a high-order step and a low-order step;

[0056] The folding step 5 has a high-level horizontal plate 51, a high-level vertical plate 52, a low-level horizontal plate 53, and a low-level vertical plate 54.

[0057] The higher-order horizontal plate 51 and the higher-order vertical plate 52 are fixedly connected and form a 90-degree outward convex angle.

[0058] The higher-order vertical plate 52 and the lower-order horizontal plate 53 are fixedly connected and form a 90-degree concave angle.

[0059] The low-order horizontal plate 53 and the low-order vertical plate 54 are hinged together.

[0060] The lower-level longitudinal plate 54 is also hinged to the connecting rod 41 or the operating platform 42 on the other side corresponding to the lower-level transverse plate 53; the first sling 6 is fixedly connected to one end of the folding step 5 on the side of the higher-level transverse plate 51 away from the higher-level longitudinal plate 52.

[0061] By fixing the angles as described above, the high-order horizontal plate 51, high-order vertical plate 52, and low-order horizontal plate 53 can maintain a Z-shaped structure with right angles at the corners, forming a stable tread surface. The high-order horizontal plate 51 is suspended by the first suspension cable 6, and the horizontality of the tread surface can be controlled by the extension of the connecting rod 41. Simultaneously, the two ends of the low-order vertical plate 54 serve as supports, keeping the high-order horizontal plate 51 and low-order horizontal plate 53 in a stable horizontal state, preventing them from collapsing under pressure. Since the hinge between the low-order horizontal plate 53 and low-order vertical plate 54 in this design does not have an angle limit, and the low-order vertical plate 54 is also hinged to the connecting rod 41 or the operating platform 42, it can be folded, allowing the height of the tread surface to be raised or lowered. The first suspension cable 6 is located on the side of the high-order horizontal plate 51 furthest from the high-order vertical plate 52, i.e., the outermost side, allowing for better support of the high-order horizontal plate 51. This is equivalent to the first suspension cable 6 and the lower longitudinal plate 54 supporting both sides of the step, resulting in better stability.

[0062] In a further preferred embodiment, the counterweight frame 1 is provided with a fixed pulley 8, and a second sling 7 is fixedly connected to one side of the lower-level horizontal plate 53 corresponding to the lower-level vertical plate 54. The other end of the second sling 7 is also fixedly connected to one side of the higher-level horizontal plate 51 corresponding to the higher-level vertical plate 52 after passing over the fixed pulley 8. The second sling 7, together with the first sling 6, keeps the higher-level horizontal plate 51 and the lower-level horizontal plate 53 horizontally positioned.

[0063] As shown in the figure, in this solution, the second suspension cable 7 can assist in suspending the high-level and low-level sections, keeping the high-level horizontal plate 51 and the low-level horizontal plate 53 horizontal, making stepping safer. As the folding state of the low-level vertical plate 54 changes, the high-level horizontal plate 51 and the low-level horizontal plate 53 can move outward and upward. At this time, the second suspension cable 7 can maintain the suspension function while allowing the high-level horizontal plate 51 and the low-level horizontal plate 53 to move outward and upward (the length of the two sections of the second suspension cable 7 can be changed through the fixed pulley 8 to adapt to the movement of the high-level horizontal plate 51 and the low-level horizontal plate 53). Of course, since the length of the second suspension cable 7 is fixed, there is also an upper limit to this movement function.

[0064] Furthermore, the second sling 7 can form a guardrail for users to hold onto, increasing safety during operation.

[0065] To facilitate operation by staff on the operating platform 42, a telescopic rod 91 is also provided at the end of the connecting rod 41 in the upper row away from the counterweight frame 1. The connecting rod 41 is also provided with a driving component 92 for driving the telescopic rod 91 to extend and retract. One end of the first sling 6 is fixedly connected to the high-level horizontal plate 51, and the other end is fixedly connected to the telescopic rod 91.

[0066] When implemented, this solution allows workers to easily enter the operating platform 42, and then extend the telescopic rod 91 via the drive component 92. This allows the first lifting cable 6, in conjunction with the second lifting cable 7, to adjust the positions of the high-level horizontal plate 51 and the low-level horizontal plate 53, facilitating elevation adjustments for workers to meet different needs. It also makes it easier for workers to operate on the operating platform 42.

[0067] In practical applications, the following settings can be used:

[0068] The driving component 92 is sleeved on the connecting rod 41 and engages with the telescopic rod 91 by rotation, thereby driving the telescopic rod 91 to extend or retract; the telescopic rod 91 and the driving component 92 are threadedly connected, and the telescopic rod 91 is driven to extend or retract through the threaded engagement.

[0069] In this design, the drive component 92 is used to rotate the telescopic rod 91. The telescopic rod 91 is driven by the threaded engagement after rotation. The two connecting rods 41 in the upper row are coaxially connected to the telescopic rod 91, which allows the telescopic rod 91 to be in the telescopic state. It is driven by the drive component 92 on one of the connecting rods 41. When the drive component 92 rotates, the telescopic rod 91 can be extended through the threaded engagement. A bearing can be installed between the drive component 92 and the connecting rod 41 to make the rotation smoother.

[0070] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
