Detailed Description

Referring to fig. 1-3, the utility model provides a technical scheme that a convenient movable overhanging operation platform is provided, wherein a main body part consists of an upper steel frame 1, a supporting part 2 and a base 3. The upper steel frame 1 is a cuboid structure formed by welding steel, the side surface of the cuboid structure forms a guardrail of the upper steel frame, the height of the guardrail is about 1000mm, and the width of the bottom surface is 800mm. The upper end face of the steel frame is provided with an opening, a wood board or a steel plate is paved on the bottom face of the steel frame, and workers can perform construction operation on the wall face in the upper steel frame 1.

As shown in fig. 2, the base 3 has a metal plate structure or a rectangular structure formed by welding a metal frame.

As shown in fig. 1 and 2, three fixed ladders 21 are welded on one side of the base 3, and the fixed ladders 21 facilitate the constructor to ascend into the upper steel frame 1. The top of fixed cat ladder 21 is in the same place with upper portion steelframe 1 welding, has more contact surfaces between three fixed cat ladder 21 and base 3 and the upper portion steelframe 1, can guarantee to support more stably to upper portion steelframe 1. The supporting rods 22 placed at oblique angles are welded between the three fixed ladders 21, as shown in fig. 2, the tops of the two supporting rods 22 are welded with the upper ends of the middle fixed ladders to form an isosceles triangle structure, the three fixed ladders 21 are connected into an integral structure, and the stability of the device is improved. The outer side of the fixed ladder 21 is also welded with an inclined rod 23, and the other end of the inclined rod 23 is welded with 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, so that stability between the upper steel frame 1 and the fixed ladder is ensured.

In this embodiment, the fixed ladder 21, the support bar 22 and the diagonal bar 23 constitute a support portion 2, the support portion 2 is located between the upper steel frame 1 and the base 3, and the support portion 2 is vertically disposed. The top of the supporting part 2 is welded with the upper steel frame 1, the bottom is welded with the base 3, and a Z-shaped structure is formed between the supporting part and the upper steel frame 1 and the base 3.

The base 3 is located at the very bottom of the whole device and serves as a carrying part and a counterweight part of the whole device. The connecting rod 31 is welded on one side of the base 3 symmetrical to the fixed ladder 21, the top of the connecting rod 31 is welded with the top of the upper steel frame 1, and a right triangle structure is formed among the connecting rod 31, the upper steel frame 1, the fixed ladder and the base 3, so that the stability of the upper steel frame 1 can be ensured.

The weight box 4 is placed on one side of the base 3 far away from the supporting part 2, as shown in fig. 1, the specific connection relation between the weight box 4 and the base 3 is not limited, the weight box can be welded with the base 3, the weight box can also be directly placed on the base 3, the upper end of the weight box 4 is of an opening structure, and materials with relatively large weight such as cement, sand or stone turning heads can be placed in the weight box. The weight box 4 plays a role of a counterweight, and when a person climbs the upper steel frame 1, the weight box 4 is used for balancing the weight of the human body. The weight of the human body and the weight of the weight box 4 can be offset from each other with the support 2 as a fulcrum. In principle, the farther the weight box 4 is from the support 2, the better.

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 external eave of the corridor is subjected to construction operation, a worker can climb on the upper steel frame 1, and putty powder or partial cement and the like are placed in the upper steel frame 1 together, so that the construction operation can be performed.

When the construction operation is performed on the corridor outer eave (such as the work of painting putty, coating cement and the like), since the putty powder, the cement and other materials and tools are directly placed on the bottom plate in the upper steel frame 1, when the construction operation is performed, personnel need to bend down to take the materials and the like, and the problem of inconvenient construction can be caused, therefore, in a further embodiment, referring to fig. 1 and 3, one side or two sides of the upper steel frame 1 are rotationally connected with the supporting plate 13 (one side is taken as an example in the figure), the bottom end of the supporting plate 13 is rotationally connected with the supporting connecting rod 11, the supporting connecting rod 11 is formed by connecting two short rods, and one ends of the two short rods are connected together through the rotating shaft 12. A baffle is fixedly arranged on the upper side of the end part of one short rod, and the end part of the baffle extends out of the short rod. One end of one of the short rods is rotatably connected with the supporting plate 13, and one end of the other short rod is rotatably connected with the side wall of the upper steel frame 1. When the two short rods directly form a straight line, the baffle plate limits the two short rods, so that the two short rods are kept on the same straight line, and the supporting plate 13 is in a horizontal state, as shown in fig. 3 and 4. When the junction of the two stubs is rotated upward, the baffle follows the stubs to rotate upward so that the two stubs fold together, as shown in fig. 5. The support plate 13 is in a downwardly inclined state in which the support plate 13 shields one side wall of the upper steel frame 1.

When the floor corridor is subjected to operations such as painting and the like, a worker can pull the edge of the supporting plate 13, so that the supporting plate 13 rotates from the inner side of the upper steel frame 1 to a position (namely, a horizontal state) vertical to the side wall of the upper steel frame 1, and an external platform is formed. At the same time, the support plate 13 rotates to drive the support link 11 to move and spread the support link 11 until the support link 11 is fully spread. Under the expansion state, the support connecting rod 11 supports the bottom end of the support plate 13, and constructors can place a brushing tool on the top end of the support plate 13, so that the constructors are prevented from bending frequently, and the constructors are convenient to take materials.

In actual construction, if the supporting plate 13 is simply configured as a flat plate structure, there is a risk that the brushing tool or putty powder falls down, and therefore, in order to improve the safety of use, a U-shaped frame 14 is further provided on the outer side of the supporting plate 13. As shown in fig. 4-6. The open side of the U-shaped frame 14 is rotatably connected with the top of the upper steel frame 1, and the two are connected together through a hinge. The U-shaped frame 14 is rotatable on the upper steel frame 1. While one end of the supporting link 11 is rotatably connected with the U-shaped frame 14 and the other end is rotatably connected with the upper steel frame 1 (the constitution of the supporting link 11 is the same as that described above, i.e., one end of one short rod is rotatably connected with the U-shaped frame and one end of the other short rod is rotatably connected with the upper steel frame 1). The U-shaped frame 14 can also be rotated to a horizontal position. And the inner side of the U-shaped frame 14 is provided with a rear chute in which a supporting plate 13 is slidably arranged. When the U-shaped frame 14 rotates, the support plate 13 can synchronously rotate along with the U-shaped frame 14. As shown in fig. 4-5, the supporting plate 13 is located inside the U-shaped frame 14, the edge of the U-shaped frame 14 protrudes upwards to form a protruding portion, and the protruding portion is located at the edge of the supporting plate 13 and has a certain shielding and limiting effect on tools placed on the supporting plate 13, so that the tools are prevented from sliding down along the upper side face of the supporting plate 13, and safety is higher.

The support plate 13 can also be used by sliding out from the U-shaped frame 14, and as shown in fig. 6, the support plate 13 can slide to the side right above the upper steel frame 1, and the position of the support plate 13 can be adjusted during construction. The support plate 13 can be selectively pulled out by different constructors. In the construction work of a person, since a space for the person to stand is relatively small, the support plate 13 can be pulled out, and a painting tool can be placed on the support plate 13. In the construction of two persons, the support plate 13 may not be pulled out because the space required for two persons to stand on the upper steel frame is relatively large.

Although an example of the present invention has been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
