Description

Technical Field

[0001] The utility model is applicable to the technical field of hanging ladders, in particular to a hanging ladder for building scaffolds. Background Art

[0002] At present, scaffolding refers to various supports set up at the construction site for workers to operate and solve vertical and horizontal transportation. In order to facilitate workers to walk and climb, hanging ladders are usually required.

[0003] However, when a construction scaffolding is used for hanging, a corresponding hanging mechanism is provided on its side. In order to ensure that the hanging mechanism and the scaffolding are in sufficient contact and fixation, the hanging mechanism cannot be quickly and conveniently adjusted for the suitability of scaffolding steel bars of different thicknesses during the process. This not only causes the operator to have too many steps to adjust the hanging mechanism, but also easily leads to insufficient contact stability between the hanging mechanism and the scaffolding steel bars, thus affecting the stability of the hanging ladder. Therefore, we propose a hanging ladder for construction scaffolding. Utility Model Content

[0004] The main purpose of the utility model is to provide a hanging ladder for building scaffolding, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A hanging ladder for building scaffolding, comprising a fixing plate, and a footrest is transversely fixedly installed between the inner sides of two sets of fixing plates;

[0007] A connecting plate is fixedly installed on the top side of each fixed plate, a rotating rod is rotatably installed between the sides of the two groups of connecting plates, fixed sleeves are fixedly sleeved on the outer side surfaces of both ends of the rotating rod, and a transmission frame is fixedly installed on the outer side surface of each fixed sleeve;

[0008] A bidirectional screw rod is rotatably installed on the inner side of each transmission frame through a bearing, and a transmission sleeve is movably sleeved on the outer end surfaces of each bidirectional screw rod through a threaded sleeve, a connecting rod is fixedly installed on the outer bottom surface of each transmission sleeve, and the connecting rod is slidably installed inside the bottom end of the transmission frame, a fitting arc plate is fixedly installed on the bottom surface of each connecting rod, and the top of the fitting arc plate is slidably fitted on the bottom surface of the transmission frame, and an anti-slip friction pad is fixedly bonded to the side surface of each fitting arc plate.

[0009] By adopting the above technical scheme, through the rotational transmission action of the bidirectional screw on the transmission sleeve and the rotational transmission action of the rotating rod, after the scaffolding steel bars for suspension are placed between the two groups of fitting arc plates, the fitting arc plates can be fitted and clamped from the outside according to the thickness of the scaffolding steel bars, thereby improving the applicability of the entire hanging ladder and the stability of the hanging ladder.

[0010] As an optional solution of the technical solution of the present application, a servo motor is fixedly installed on the inner side of each transmission frame, and the side edges of the servo motor transmission shaft are fixedly connected to the outer top end surface of the bidirectional screw rod through a coupling.

[0011] By adopting the above technical solution, the corresponding power source is provided for the rotation of the bidirectional screw rod through the structural function of the servo motor.

[0012] As an optional solution to the technical solution of the present application, rotating plates are fixedly installed on the outer side surfaces of both ends of the rotating rod, and the rotating plates are movably fitted to the outer side of the connecting plate. A movable plate is fixedly installed on the outer top surface of each rotating plate, and a limiting baffle is fixedly installed on the outer side surface of each connecting plate.

[0013] By adopting the above technical solution, the transmission rationality of the entire device is ensured by the limiting action of the limiting baffle on the moving plate.

[0014] As an optional solution of the technical solution of the present application, a limiting groove is provided at the middle end of the bottom of each transmission frame, and the connecting rod is slidably installed inside the limiting groove.

[0015] By adopting the above technical solution, the transmission rationality of the entire device is ensured by the guiding and limiting effect of the limiting groove on the connecting rod.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application is a hanging ladder for building scaffolding. By sleeve-connecting a transmission sleeve on both sides of a bidirectional screw rod and combining the rotational transmission action of the bidirectional screw rod on the transmission sleeve, the transmission sleeves on both sides of the bidirectional screw rod can be synchronously moved toward or relative to each other. Subsequently, under the transmission action of the connecting rod, the fitting arc plates on both sides of the bottom of the transmission frame can be driven to move horizontally toward or relative to each other synchronously. After the scaffolding steel bars for hanging are placed between the two groups of fitting arc plates, the fitting arc plates can be fitted and clamped from the outside according to the thickness of the scaffolding steel bars, thereby improving the applicability of the entire hanging ladder and improving the stability of the hanging ladder.

[0018] 2. The technical solution of the present application is a hanging ladder for building scaffolding, in which a transmission frame and a fitting arc plate are rotatably installed on the outside of a rotating rod by a rotating rod, and under the transmission action of the rotating plate, the limiting baffle plate performs a limiting treatment on the movable plate, thereby ensuring that the transmission frame and the fitting arc plate can be rotated and folded for convenient storage. At the same time, when the hanging ladder is hung for use, the rotating rod will not rotate excessively, thereby ensuring the safety of the hanging ladder in hanging use.

DETAILED DESCRIPTION

[0023] like Figure 1-3 As shown, the utility model provides a technical solution: a hanging ladder for building scaffolding, each fixed plate 1 is fixedly installed with a connecting plate 2 on the top side, a rotating rod 21 is rotatably installed between the sides of two groups of connecting plates 2, and the outer end surfaces of the rotating rod 21 are fixedly sleeved with fixed sleeves 25, and the outer surface of each fixed sleeve 25 is fixedly installed with a transmission frame 26.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), rotating plates 22 are fixedly installed on the outer side surfaces of both ends of the rotating rod 21, and the rotating plates 22 are movably fitted to the outer side of the connecting plate 2, and a movable plate 23 is fixedly installed on the outer top surface of each rotating plate 22, and a limit baffle 24 is fixedly installed on the outer side surface of each connecting plate 2.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a servo motor is fixedly installed on the inner side of each transmission frame 26, and the side edges of the servo motor transmission shaft are fixedly connected to the outer top surface of the bidirectional screw rod 3 through a coupling.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a bidirectional screw rod 3 is rotatably installed on the inner side of each transmission frame 26 through a bearing, and a transmission sleeve 31 is movably sleeved on the outer end surfaces of each bidirectional screw rod 3 through a threaded sleeve, and a connecting rod 32 is fixedly installed on the outer bottom surface of each transmission sleeve 31, and the connecting rod 32 is slidably installed inside the bottom end of the transmission frame 26, and a fitting arc plate 27 is fixedly installed on the bottom surface of each connecting rod 32, and the top of the fitting arc plate 27 is slidably fitted to the bottom surface of the transmission frame 26, and an anti-slip friction pad 4 is fixedly bonded to the side surface of each fitting arc plate 27.

[0028] During operation, when the hanging ladder composed of the fixed plate 1 and the pedal rod 11 needs to be hung for use, the transmission frame 26 is pulled outward to rotate it from a side parallel to the pedal rod 11. After the pedal rod 11 is in a vertical state, the pedal rod 11 to be hung is placed between the two sets of fitting arc plates 27, and the servo motor is turned on through an external hollow control switch to make it run and drive the bidirectional screw rod 3 to rotate accordingly. Combined with the guiding and limiting effect of the limit groove 33 on the connecting rod 32, the bidirectional screw rod 3 is After the rotation occurs, the transmission sleeves 31 on both sides of the outside can move horizontally toward each other synchronously, and then under the transmission action of the connecting rod 32, the fitting arc plates 27 located on the outside of the scaffolding steel bars can move toward each other and fit against the outside of the steel bars, thereby actuating and fixing the hanging steel bars. The hanging ladder is then hung outside the scaffolding for climbing use. Under the actuating and limiting action of the limit baffle 24 on the actuating plate 23, the hanging ladder will not rotate relative to the transmission frame 26 at will, thereby affecting the stability of climbing use.
