Description

Technical Field

[0001] The invention relates to the field of lifting scaffolds, in particular to a lifting scaffold suitable for inclined building surfaces. Background Art

[0002] The attached lifting scaffolding equipment is a new type of scaffolding technology that has developed rapidly at the beginning of this century and has an important impact on the progress of my country's construction technology. It changes high-altitude operations into low-altitude operations and aerial operations into internal operations of the frame. It has significant low-carbon, high-tech content, and is more economical, safer, and more convenient.

[0003] An attached lifting scaffolding refers to an external scaffolding that is erected at a certain height and attached to an engineering structure, relying on its own lifting equipment and devices, and can climb or descend layer by layer with the engineering structure, and has anti-overturning and anti-falling devices; the attached lifting scaffolding is mainly composed of an attached lifting scaffolding frame structure, a wall-mounted support base, an anti-overturning device, an anti-falling device, a lifting mechanism and a control device.

[0004] The existing lifting scaffolding support part generally includes a vertically arranged load-bearing plate and a protective plate, which are fixed to the guide rails and driven to rise or fall by the guide rails.

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1 As shown, combined Figure 2 and Figure 3 The lifting scaffolding suitable for inclined building surfaces of the present invention includes a guide rail, a gear 1, a wall-mounted support mechanism 4, a bracket 5 and a hinge 6.

[0029] The guide rail includes a load-bearing beam 21 and a movable beam 25 which are hinged to each other. The load-bearing beam 21 is slidably connected or rollingly connected to the wall-mounted support mechanism 4. The bracket 5 includes a telescopic rod 50, a protective plate 51 and a plurality of load-bearing plates 52. The two ends of the plurality of load-bearing plates 52 are respectively vertically fixed to the protective plate 51 and the movable beam 25. The two ends of the telescopic rod 50 are respectively hinged to the protective plate 51 and the load-bearing beam 21. In this way, the telescopic rod 50 is extended to drive the movable beam 25 to rotate around the load-bearing beam 21, so that the protective plate 51 can be adjusted to the vertical direction and the load-bearing plate 52 can be adjusted to the horizontal state, which is convenient for construction workers to stand and operate. Specifically, as Figure 8 As shown, the telescopic rod 50 includes a first screw rod 501, a second screw rod 502 and a wire drum 503. One end of the first screw rod 501 and the second screw rod 502 are respectively hinged to the protective plate 51 or the load-bearing beam 21, and the other end extends into the wire drum 503 and is threadedly connected thereto. The first screw rod 501 and the second screw rod 502 are wound in opposite directions. In this way, by rotating the wire drum 503, the first screw rod 501 and the second screw rod 502 can be driven to move toward or away from each other, thereby achieving a telescopic effect. In order to facilitate the rotation of the wire drum 503, the telescopic rod 50 also includes a cross bar 504, which is vertically arranged on the surface of the wire drum 503.

[0030] The telescopic rod 50 can be directly hinged to the protective plate 51. As another embodiment, the bracket 5 further includes a top plate 53 and a movable protective plate 54, one end of the top plate 53 is vertically fixed to the movable protective plate 54, and the other end is hinged to the load-bearing beam 21, the movable protective plate 54 is hinged to the protective plate 51, and the telescopic rod 50 is hinged to the top plate 53 and the load-bearing beam 21, respectively. In this way, the telescopic rod 50 is subjected to more stable force.

[0031] The hinge 6 serves as a hinge connection between the load-bearing beam 21 and the movable beam 25 or between the movable protective plate 54 and the protective plate 51. Figure 4 As shown, it includes two connecting tubes 61, two connecting pieces 62 and two bolts 63. Through holes are respectively arranged on the side faces of the heads of the two connecting tubes 61. The two connecting pieces 62 are respectively arranged on both sides of the heads of the two connecting tubes 61. Through holes are respectively arranged on the heads and tails of the connecting pieces 62. The two bolts 63 respectively pass through the two connecting pieces 62 and the two connecting tubes 61 and fasten the two together. The two connecting tubes 61 are respectively fixedly connected to the load-bearing beam 21 and the movable beam 25. Specifically, the two connecting tubes 61 are respectively fixedly connected to the movable protective plate 54 and the protective plate 51, playing the role of hinge connection between the two.

[0032] In order to drive the guide rail to move on the inclined building surface, a gear 1 is also included, such as Figure 5 The guide rail includes a linear rack 31 and an I-shaped channel steel 32. A linear groove 33 is formed on the surface of the I-shaped channel steel 32. The linear rack 31 is embedded in the linear groove 33 and fixed to the I-shaped channel steel 32. The gear 1 is meshed with the linear rack 31 and is rotatably connected to the load-bearing beam 21. The load-bearing beam 21 is arranged parallel to the linear rack 31 and is slidably or rollingly connected to the I-shaped channel steel 32. The wall-mounted support mechanism 4 includes a wall-mounted seat 41, which is slidably or rollingly connected to the I-shaped channel steel 32. Specifically, the I-shaped channel steel 32 can be formed by welding two channel steels and a strip of steel plate, or it can be formed in one piece.

[0033] Specifically, the specific connection method between the load-bearing beam 21 and the I-shaped channel steel 32 is as follows: Figure 6 The guide rail includes a first limit block 22, and the first limit block 22 includes a slip ring 221. A limit groove 221 is arranged on the surface of the first limit block 22. The two protruding side edges of the I-shaped channel steel 32 are respectively embedded in the limit groove 221. The slip ring 221 is arranged in the limit groove 221 and is arranged opposite to the protruding side edges of the I-shaped channel steel 32. The first limit block 22 is fixed to the load-bearing beam 21. In this way, the limit groove 221 can prevent the load-bearing beam 21 and the I-shaped channel steel 32 from moving in the opposite direction, and the slip ring 221 can prevent the load-bearing beam 21 and the I-shaped channel steel 32 from moving in the left and right directions, and play a role in guiding and reducing friction. In order to reduce the movement friction between the load-bearing beam 21 and the I-shaped channel steel 32 during the relative lifting process, as Figure 3As shown, the main beam 2 includes at least two sets of guide wheels 23 , which are respectively arranged on both sides of the load-bearing beam 21 and rotatably connected thereto, and are rollingly connected to the surface of the I-shaped channel steel 32 .

[0034] Specifically, the wall mount 41 is connected to the I-shaped channel steel 32 in the following manner: Figure 7 The wall-mounted support mechanism 4 includes two groups of rollers 44 and two arc-shaped sliders 43. The arc-shaped sliders 43 and rollers 44 are respectively arranged on the upper and lower surfaces of the two protruding side edges of the I-shaped channel steel 32. The arc-shaped sliders 43 are fixed to the wall-mounted seat 41, and the rollers 44 are rotatably connected to the wall-mounted seat 41. In this way, when the I-shaped channel steel 32 and the wall-mounted seat 41 move relative to each other and cause bumps, the arc-shaped sliders 43 and rollers 44 can play a role in reducing friction.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
