The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0022] See also Figures 1 to 6 The utility model preferably provides a technical solution: an anti-fall climbing device for elevator shaft construction, comprising: two brackets 1, and transmission components respectively arranged on the opposite sides of the two brackets 1, and the transmission components can move in the X and Y directions; it also includes a climbing platform component arranged on the two sets of transmission components, when the transmission component runs in the Y direction, it is used to drive the climbing platform component to rise and fall; and a locking structure arranged on the climbing platform component, when the transmission component runs in the X direction, it is used to drive the locking structure to act on the two brackets 1 and lock the climbing platform component after it is raised and lowered.

[0023] The utility model, such as Figure 1 , 2As shown in , 3, the transmission assembly can move in the X and Y directions. When it moves in the Y direction, it can drive the climbing platform assembly arranged thereon to move up and down to meet the lifting and lowering needs of workers in the elevator shaft. When it moves in the X direction, it can act on the locking structure, and the locking structure can lock the climbing platform assembly after lifting, so as to ensure the stability of the climbing platform assembly after lifting, thereby reducing the risk of the climbing platform assembly falling.

[0024] The structural characteristics of the climbing platform assembly can provide safety protection for construction workers when the transmission assembly moves in the Y direction.

[0025] In this process, the transmission assembly moves in two directions. When it moves in the Y direction, it can drive the climbing platform assembly to rise and fall, thereby meeting the lifting and falling needs of the workers during construction. When it moves in the X direction and acts on the locking structure, the locking structure can lock the climbing platform assembly after lifting and falling, reducing the risk of the climbing platform assembly falling. At the same time, through the structural characteristics of the climbing platform assembly, the safety protection of the construction personnel is further realized, thereby improving the safety and stability of the workers' construction.

[0026] Furthermore, each group of transmission components includes two first slide grooves opened on the bracket 1, and a first transmission plate 2 which is transversely installed inside the two first slide grooves and can move longitudinally; it also includes a second slide groove opened on the first transmission plate 2, and a second transmission plate 3 which can slide transversely is arranged inside the second slide groove, and the climbing platform assembly is arranged on the second transmission plate 3 where the two groups of transmission components are located; two first transmission wheels 17 and two drive motors 12 are respectively arranged at both ends of the bracket 1, and a drive wheel 13 fixed at the output end of each drive motor 12; two second transmission wheels 14 are also rotatably installed at both ends of the first transmission plate 2; it also includes a transmission rope 16 which is sleeved on the first transmission wheel 17, the drive wheel 13, and the second transmission wheel 14, and the transmission rope 16 passes through the through groove opened on the second transmission plate 3 and is fixedly connected to the second transmission plate 3.

[0027] Here, the first transmission plate 2 is transversely mounted on the two brackets 1 and can slide longitudinally inside the first slide groove where the bracket 1 is located, and the second transmission plate 3 is arranged on the first transmission plate 2 and can slide transversely inside the second slide groove where the first transmission plate 2 is located, so that the second transmission plate 3 can move in the X and Y directions, and the movement can be as follows Figure 1 , 4 As shown, the transmission rope 16 is sleeved on the first transmission wheel 17, the driving wheel 13, and the second transmission wheel 14 and fixed to the second transmission plate 3. Therefore, by adjusting the rotation direction of the two driving wheels 13, the switching process of the movement direction of the climbing platform assembly can be achieved, such as Figure 4As shown, when the two driving wheels 13 are rotated in opposite directions, the first transmission plate 2 is moved in the Y direction by the action of the transmission rope 16, so that the second transmission plate 3 on the first transmission plate 2 and the climbing platform assembly on the second transmission plate 3 are raised or lowered;

[0028] When the two driving wheels 13 run in the same direction, the first transmission plate 2 remains stationary, and the second transmission plate 3 on the first transmission plate 2 can move in the X direction on the first transmission plate 2, thereby driving the locking structure to act on the bracket 1. Figure 4 As shown, when the two driving wheels 13 are deflected counterclockwise, the second transmission plate 3 can move to the right on the first transmission plate 2 to enable the climbing platform assembly to achieve the locking process of the lifting position. Similarly, when the two driving wheels 13 run clockwise, the second transmission plate 3 can move to the left on the first transmission plate 2 to achieve the unlocking process of the climbing platform assembly.

[0029] Furthermore, the climbing platform assembly includes a lifting platform 4, which is fixedly mounted on the top of the second transmission plate 3 where the two groups of transmission assemblies are located, and a guardrail 5 arranged on the upper surface of the lifting platform 4, and also includes a baffle assembly arranged on the upper surface of the lifting platform 4, and the baffle assembly and the guardrail 5 together constitute a rectangular enclosure structure.

[0030] Here, the rectangular enclosure structure formed by the baffle assembly and the guardrail 5 can be as follows: Figure 6 As shown, this design ensures the safety of construction workers during lifting and lowering, and through the structural characteristics of the baffle assembly, it can be used as an electromagnetic door structure. During the lifting and lowering process of the lifting platform 4, the electromagnetic door remains closed to reduce the risk of workers falling from the lifting platform 4. When the lifting platform 4 moves horizontally, that is, when the locking structure is triggered, the electromagnetic door is powered off and is in an open state, as shown in FIG. Figure 1 , 5 As shown, it is convenient for workers to enter and exit the elevator entrance and carry out construction operations.

[0031] Furthermore, the baffle assembly includes a slide rail 6 fixed on the lifting platform 4, with fixed plates respectively provided at both ends of the slide rail 6, and two movable plates 7 arranged inside the slide rail 6 and capable of limited sliding, and the fixed plate and the movable plate 7 constitute one side wall of the rectangular enclosure structure; it also includes an electromagnetic structure arranged between the two movable plates 7, when the transmission assembly drives the climbing platform assembly to rise and fall, the electromagnetic structure is energized so that the two movable plates 7 fit tightly together, and when the transmission assembly drives the locking structure to act on the two brackets 1, the electromagnetic structure is de-energized so that the two movable plates 7 open.

[0032] Here, the fixed plates at both ends of the slide rail 6 and the movable plates 7 inside the slide rail 6 can together constitute the side walls of the rectangular enclosure structure, and cooperate with the electromagnetic structure set on the opposite surfaces of the two movable plates 7 to form the above-mentioned electromagnetic door body. The closing and opening process of the electromagnetic door body is further realized by turning on and off the power of the electromagnetic structure.

[0033] Furthermore, the electromagnetic structure includes a first electromagnetic sheet 8 and a second electromagnetic sheet. The first electromagnetic sheet 8 and the second electromagnetic sheet are respectively arranged on opposite sides of the two movable plates 7 and are magnetically attracted to each other.

[0034] Since the first electromagnetic sheet 8 and the second electromagnetic sheet are magnetically attracted to each other, Figure 6 As shown, when the first electromagnetic plate 8 and the second electromagnetic plate are powered on and off, the two movable plates 7 can be opened and closed, and the power on and off of the two sides are triggered by the locking structure.

[0035] Furthermore, handles 15 are fixed to the two movable plates 7 on one side close to the guardrail 5. Figure 6 As shown, the opening of the two movable panels 7 is facilitated.

[0036] Furthermore, two groups of locking structures are provided, each group of locking structures includes a plug-in frame 9 and a plug-in column 18, and the plug-in frame 9 and the plug-in column 18 are respectively arranged on both sides of the lifting platform 4; and a first socket slot 10 and a second socket slot 11 are respectively opened on the side wall of the bracket 1, and the plug-in frame 9 and the plug-in column 18 are respectively adapted to be plugged in with the first socket slot 10 and the second socket slot 11; and also include pressure-sensitive switches respectively arranged at the ends of the plug-in frame 9 and the plug-in column 18, and when the plug-in frame 9 and the plug-in column 18 are respectively plugged in with the first socket slot 10 and the second socket slot 11, the pressure-sensitive switch is triggered to cut off the power to the electromagnetic structure.

[0037] Since the plug-in frame 9 and the plug-in column 18 are fixed on both sides of the lifting platform 4, the lifting platform 4 moves in the X direction through the transmission assembly, that is, Figure 4 When moving left and right as shown, the plug-in frame 9 and the plug-in column 18 can be respectively plugged into and disengaged from the first plug-in slot 10 and the second plug-in slot 11 on the bracket 1, thereby realizing the locking and unlocking process after the lifting platform 4 is lifted;

[0038] Since the ends of the plug-in frame 9 and the plug-in column 18 are respectively provided with pressure-sensitive switches, when the plug-in frame 9 and the plug-in column 18 are respectively inserted into (disengaged from) the first jack slot 10 and the second jack slot 11, the electromagnetic structure is powered off (powered on), and the power-off state is as follows: Figure 1 , 4 As shown in , 5, when the pressure-sensitive switch is triggered, the single-chip microcomputer inside the device receives a signal to drive the first electromagnetic plate 8 and the second electromagnetic plate to cut off power, so that when the lifting platform 4 is in a locked state, the two movable plates 7 are in an open state, which is convenient for workers to enter and exit the elevator.
