Description

Technical Field

[0001] The utility model relates to the technical field of construction devices, and more specifically to a convenient movable cantilever operating platform. Background Art

[0002] Cantilever operating platforms are temporary operating platforms or operating frames often set up at construction sites for various masonry, decoration and painting operations. Generally speaking, they can be used to carry materials and perform various operations within a certain construction period. Mobile cantilever operating platforms are mostly used for outdoor decoration projects, especially for painting and paving the outside of corridors. For example, the painting of the exterior of the corridors in schools. When dealing with new types of painting and paving inside and outside the floors, it is usually necessary to use external cranes to raise the position of construction workers or build scaffolding, or use hanging ropes. Workers working on the hanging ropes are often called "Spider-Man". One of the above two construction methods is more expensive, and the other is more risky.

[0003] For this reason, there is a cantilever mobile platform. With an independent cantilever platform, construction workers can directly construct on the platform, which is safer and more convenient. For example, a movable cantilever operating platform disclosed in Chinese patent number CN218091924U. However, in actual use, it is necessary to inspect the device before use, check and clarify the overall and local vertical deviations of the scaffolding, and pay special attention to the verticality of the corners and fractures of the scaffolding. However, the combined frame welded together as a whole can only bear its own gravity and the gravity of the material it carries by relying on the welding points between the base, the upper steel frame and the support part. The supports between the two are not only prone to abnormal situations, but also difficult to detect abnormal verticality in time. At the same time, the materials needed by the construction workers are mostly placed in the upper steel frame. When the construction workers are performing operations such as painting that require multiple material collection, they need to bend over frequently, which is very easy to damage the construction workers' bodies and also reduces work efficiency. In view of this, we propose a convenient movable cantilever operating platform. Utility Model Content

[0027] See also Figure 1-3 The utility model provides a technical solution: a convenient movable cantilever operating platform, the main part of which is composed of an upper steel frame 1, a support part 2 and a base 3. The upper steel frame 1 is a rectangular parallelepiped structure welded from steel materials, and the side of the rectangular parallelepiped structure forms a guardrail of the upper steel frame, the height of the guardrail is about 1000mm, and the bottom width is 800mm. The upper end surface is an open setting, and the bottom surface is paved with wooden boards or steel plates, and personnel can perform construction work on the wall in the upper steel frame 1.

[0028] like Figure 2 As shown, the base 3 is a metal plate structure or a rectangular structure formed by welding metal frames.

[0029] like Figure 1and Figure 2 As shown, three fixed ladders 21 are welded on one side of the base 3, and the fixed ladders 21 facilitate construction workers to climb up and enter the upper steel frame 1. The top of the fixed ladder 21 is welded to the upper steel frame 1, and there are more contact surfaces between the three fixed ladders 21 and the base 3 and the upper steel frame 1, which can ensure that the upper steel frame 1 is supported more stably. An obliquely placed support rod 22 is welded between the three fixed ladders 21, as shown in FIG. Figure 2 As shown, the tops of the two support rods 22 are welded to the upper end of the middle fixed ladder to form an isosceles triangle structure, connecting the three fixed ladders 21 into an integral structure to improve the stability of the device. An inclined rod 23 is also welded to the outside of the fixed ladder 21, and the other end of the inclined rod 23 is welded to the bottom of the upper steel frame 1. The inclined rod 23 is in an inclined state, and can form a triangular support between the bottom end of the upper steel frame 1 and the fixed ladder 21, ensuring the stability between the upper steel frame 1 and the fixed ladder.

[0030] In this embodiment, the fixed ladder 21, the support rod 22 and the inclined rod 23 constitute the support part 2, and the support part 2 is located between the upper steel frame 1 and the base 3, and the support part 2 is vertically arranged. The top of the support part 2 is welded to the upper steel frame 1, and the bottom is welded to the base 3, forming a "Z"-shaped structure with the upper steel frame 1 and the base 3.

[0031] The base 3 is located at the bottom of the entire device, serving as the bearing part and counterweight part of the entire device. A connecting rod 31 is welded on one side of the base 3 that is symmetrical to the fixed ladder 21, and the top of the connecting rod 31 is welded to the top of the upper steel frame 1. A right triangle structure is formed between the connecting rod 31, the upper steel frame 1, the fixed ladder and the base 3, which can ensure the stability of the upper steel frame 1.

[0032] A counterweight box 4 is placed on one side of the base 3 away from the support portion 2. Figure 1 As shown, the specific connection relationship between the counterweight box 4 and the base 3 is not limited. It can be welded to the base 3 or placed directly on the base 3. The upper end of the counterweight box 4 is an open structure, and heavy materials such as cement, sand or stone can be placed in the counterweight box. The counterweight box 4 plays the role of counterweight. When a person climbs onto the upper steel frame 1, the counterweight box 4 is used to balance the weight of the human body. The weight of the human body and the gravity of the counterweight box 4 can offset each other with the support part 2 as the fulcrum. In principle, the farther the counterweight box 4 is from the support part 2, the better.

[0033] An opening is left at the position where the upper steel frame 1 is opposite to the fixed ladder 21, so that the staff can enter the upper steel frame 1. When the corridor eaves are being constructed, the staff can climb onto the upper steel frame 1, putty powder or part of cement is placed in the upper steel frame 1, and the construction work can be carried out.

[0034] When the exterior of the corridor is under construction (such as painting putty, applying cement, etc.), since materials and tools such as putty powder or cement are directly placed on the bottom plate in the upper steel frame 1, during the construction, personnel need to bend down to take materials, etc., which will cause inconvenience in construction. Therefore, in a further embodiment, reference is made to Figure 1 and Figure 3 One side or both sides of the upper steel frame 1 are rotatably connected to a support plate 13 (one side is taken as an example in the figure), and the bottom end of the support plate 13 is rotatably connected to a support connecting rod 11. The support connecting rod 11 is formed by two short rods, and one end of the two short rods are connected together by a rotating shaft 12. A baffle is fixedly installed on the upper side of the end of one of the short rods, and the end of the baffle extends from the short rod. One end of one of the short rods is rotatably connected to the support plate 13, and one end of the other short rod is rotatably connected to the side wall of the upper steel frame 1. When the two short rods directly form a straight line, the baffle limits the two short rods so that the two short rods remain in the same straight line, and the support plate 13 is in a horizontal state. Figure 3 Shown and Figure 4 When the connection of the two short rods rotates upward, the baffle rotates upward along with the short rods, so that the two short rods are folded together, as shown in FIG. Figure 5 The support plate 13 is in a downwardly inclined state, in which the support plate 13 can shield a side wall of the upper steel frame 1 .

[0035] When painting inside and outside the corridor, the staff can pull the edge of the support plate 13 to rotate the support plate 13 from the inside of the upper steel frame 1 to a position perpendicular to the side wall of the upper steel frame 1 (i.e., horizontal state), forming an external platform. At the same time, the rotation of the support plate 13 drives the support link 11 to move and spread the support link 11 until the support link 11 is fully unfolded. In the unfolded state, the support link 11 supports the bottom end of the support plate 13, and the construction personnel can place the painting tools on the top of the support plate 13, thereby avoiding the construction personnel from bending over frequently and facilitating the construction personnel to carry out material collection operations.

[0036] In actual construction, if the support plate 13 is simply set as a flat plate structure, there is a risk of brush tools or putty powder falling on it. Therefore, in order to improve the safety of use, a U-shaped frame 14 is also provided on the outer side of the support plate 13. Figure 4-Figure 6As shown. The open side of the U-shaped frame 14 is rotatably connected to the top of the upper steel frame 1, and the two are connected together by a hinge. The U-shaped frame 14 can rotate on the upper steel frame 1. One end of the support link 11 is rotatably connected to the U-shaped frame 14, and the other end is rotatably connected to the upper steel frame 1 (the component structure of the support link 11 is the same as above, that is, one end of a short rod is rotatably connected to the U-shaped frame, and one end of the other short rod is rotatably connected to the upper steel frame 1). The U-shaped frame 14 can also be rotated to a horizontal state. A rear slide groove is provided on the inner side of the U-shaped frame 14, and a support plate 13 is slidably installed in the slide groove. When the U-shaped frame 14 rotates, the support plate 13 can rotate synchronously with the U-shaped frame 14. As shown Figure 4-Figure 5 As shown, the support plate 13 is located inside the U-shaped frame 14, and the edge of the U-shaped frame 14 protrudes upward to form a raised portion. The raised portion is located at the edge of the support plate 13, which has a certain shielding and limiting effect on the tools placed on the support plate 13, preventing the tools from sliding along the upper side of the support plate 13, and providing higher safety.

[0037] The support plate 13 can also be slid out of the U-shaped frame 14 for use. Figure 6 As shown, the support plate 13 can slide to the side just above the upper steel frame 1. During construction, the position of the support plate 13 can be adjusted. The support plate 13 can be selectively pulled out according to the number of construction workers. When one person is working, since the space for one person to stand is relatively small, the support plate 13 can be pulled out and the painting tools can be placed on the support plate 13. When two people are working, since the space required for two people to stand on the upper steel frame is relatively large, the support plate 13 can be left unpulled.

[0038] Although examples of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
