A fully steel attached lifting scaffold

Abstract

The present invention discloses an all-steel attached lifting scaffold, including a scaffold body, a cargo elevator, a wall-attached guide seat and a wall-attached hanging seat. The scaffold body includes two main frames and three sub-frames arranged between the two main frames. The cargo elevator is located between the two scaffold bodies. The present invention relates to the technical field of scaffolds. In the all-steel attached lifting scaffold, when the cargo elevator is arranged between two groups of scaffolds, a protective device is used at the joint of the two groups of scaffolds. During the lifting process, if the scaffold falls, the cooperation between the movable plate and the connecting rod can play an anti-falling effect and improve the overall safety. The base of the wall-attached guide seat uses 12, 10, and 6 mm thick steel plates to prefabricate the bottom plate, front plate, left and right side plates, and upper and lower cover plates. Through optimized combination, the mortise and tenon method is used to assemble and weld them into one, so that the production error in the production process is reduced to the lowest, and the structural strength is more stable and firm than traditional assembly welding.

It is mainly used in exterior walls, interior decoration or places with high floor heights that cannot be directly constructed. It is mainly for construction workers to work up and down or maintain the outer safety net and install components at high altitude. It is usually made of bamboo, wood, steel pipes or synthetic materials. Early attached lifting scaffolding used a fixed vertical frame, horizontal supporting trusses and steel pipe fasteners to assemble the frame on site. The attached support was installed on the wall, the upper hook of the electric hoist was hung on the attached support, and the lower hook lifted the frame. The electric hoist was powered on to lift the frame. Because of its simple structure and easy use, it has been promoted and applied in the construction industry.

[0036] The longitudinal members of the scaffolding, such as the steel scaffolding board 104 and the horizontal truss 106, are directly connected to both sides of the inner and outer uprights. The section lengths of the steel scaffolding board 104 and the horizontal truss 106 are in a modulus with the machine span.

A spring 14 is fixedly connected to the inside of one side of the connecting plate 7, and the bottom end of the spring 14 is fixedly connected to the top of the movable plate 8. The above-mentioned connecting rod 9, movable plate 8, connecting plate 7, sliding rod 10 and slide plate 11 correspond to each other up and down in the outer frame 5 and the shell 6 respectively, and at least two groups are set.

[0038] In the present invention, Z-shaped struts 103 are fixedly connected to the inside of the main frame 101 and the sub-frame 102, and scaffolding boards 104 are connected between the Z-shaped struts 103 on the main frame 101 and the sub-frame 102, and protective meshes 105 are connected to the fronts between the main frame 101 and the sub-frame 102 and between the two sub-frames 102, and horizontal trusses 106 are connected between the main frame 101 and the sub-frame 102, between the two sub-frames 102 and below the scaffolding boards 104.

[0040] In the present invention, the top and bottom of both sides of the two main frames 101 are connected with a hanger 109, and an electric hoist 110 is arranged between the two hangers 109. The hanger 109 is an important component of the lifting system of the attached lifting scaffold, and is a load-bearing structural component for fixing the upper and lower hanging points of the electric hoist 110. Ordinary general hangers are divided into upper and lower two different structures. Considering that their functions are the same, they are set as universal parts to avoid the need to set corresponding components for different upper, lower and left and right installation directions, thereby fundamentally reducing the workload of equipment storage management and production maintenance.

[0041] In the present invention, the backs of the two main frames 101 are connected to guide rails 111, and a cross bar 112 is fixedly connected between the two sides of the inner wall of the guide rail 111, the top of the back of the guide rail 111 is connected to a pull-up seat plate 113, and the inside of the pull-up seat plate 113 is rotatably connected to an adjusting rod 114, and the bottom of the adjusting rod 114 is rotatably connected to a pull-down seat plate 115.

[0042] On the structural surface of the installation layer of the top wall-attached guide seat 3, two M12 expansion bolts are used to fix the lower seat plate 115 made of Q235B steel. On the anti-falling ladder rod on the guide rail 111, an upper seat plate 113 made of the same material is installed. One end of the seat plate presses against the front of the guide rail 111, and the other end presses against the anti-falling ladder rod to form a hoop. A pull rod with adjustable length is installed between the upper and lower seat plates. The two ends are fastened to the seat plates with M16 bolts. The pull rod is composed of a 50×3 square tube and a Ø30 left-right hand thread bolt. The transverse spacing is not greater than 6 meters, and the corner spacing is not greater than 2 meters.

[0043] In the present invention, the wall-attached guide seat 3 includes a base 31. Both the front and rear of the inner wall of one side of the base 31 are rotatably connected with a guide wheel group 32, and the guide wheel group 32 is slidably connected with one side of the guide rail 111.

[0044] For the base 31 of the wall-attached guide seat 3, prefabricated bottom plates, front plates, left and right side plates, and upper and lower cover plates made of steel plates with thicknesses of 12, 10, and 6 mm are selected. Through optimized combination and assembled and welded together in a tenon-mortise manner, the manufacturing error during the production process is reduced to the lowest level, and the structural strength is more stable and firm than traditional assembled welding.

[0045] In the present invention, a right-hand thread long rod 33 is rotatably connected to the top of the base 31, and a left-right hand thread adjusting bolt 34 is threadedly connected inside the right-hand thread long rod 33. The top of the surface of the left-right hand thread adjusting bolt 34 is threadedly connected with a left-hand thread short rod 35.

[0046] In the present invention, a connecting block 36 is arranged inside the base 31. An anti-falling block 37 is rotatably connected inside the connecting block 36, and a movable pendulum 38 is fixedly connected to the front of the anti-falling block 37.

[0047] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0048] During use, when it is necessary to remove the scaffolding main body 1 above the freight elevator 2, the crane hoists the scaffolding main body 1 upward. During the upward movement of the outer shell 6, the movable plate 8 will flip downward under the block of the connecting rod 9. If it suddenly falls, the movable plate 8 will be located above the connecting rod 9 to prevent the outer shell 6 from continuing to descend, playing a certain protective role. When one of the scaffolding main bodies 1 descends rapidly, the cross bar 112 on its guide rail 111 will drive the anti-falling block 37 and the movable pendulum 38 to rotate. When the speed is too fast, the anti-falling block 37 will get stuck between the cross bars 112 to prevent the scaffolding main body 1 from continuing to descend.

[0049] It should be noted that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
