[0022] The utility model is described in detail below in conjunction with the accompanying drawings.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Example 1

[0025] like Figure 1-3 The safety belt hanging device for an H-beam shown includes a safety belt 2 for construction workers to wear, and a hanging device 1 is provided on the safety belt 2, through which the construction workers can hang with the H-beam, and a control device 14 is also provided on the hanging device 1 for the construction workers to operate conveniently, so that the construction workers can control the opening and closing of the hanging device 1 through the control device 14 to achieve connection with the H-beam;

[0026] Furthermore, the suspension device 1 includes a telescopic rod 12, the upper end of which is connected to a clamping device 11 that can be opened and closed, and a control device 14 is connected to the clamping device 11 to control the opening and closing of the clamping device 11, so that construction workers can first connect the clamping device 11 to the H-shaped steel through the telescopic rod 12 and the operating device 14 at a low place, which is convenient for subsequent use.

[0027] As mentioned above, the clamping device 11 includes a first clamping claw 111, and the first clamping claw 111 is fixedly connected to one end of the telescopic rod 12, and the clamping device 11 also includes a second clamping claw 113;

[0028] Furthermore, the second clamping claw 113 is hinged to the first clamping claw 111, and the second clamping claw 113 can rotate around the hinge. When the first clamping claw 111 does not rotate and the second clamping claw 113 rotates, the clamping device 11 can be opened and closed, such as Figure 2 shown.

[0029] As mentioned above, a first connection 1111 is provided on the inner side of the first clamping claw 111, and a second connection 1132 is also provided on the inner side of the second clamping claw 113, and a spring member 112 is provided between the first clamping claw 111 and the second clamping claw 113, one end of the spring member 112 is connected to the first connection 1111, and the other end of the spring member 112 is connected to the second connection 1132. In this way, when the second clamping claw 113 is opened, since the first clamping claw 111 remains stationary, the spring member 112 is stretched at this time, until the clamping device 11 is connected to the H-shaped steel, the spring member 112 retracts to drive the second clamping claw 113 to reset, thereby ensuring the connection stability between the clamping device 11 and the H-shaped steel, as shown in FIG. Figure 2 shown.

[0030] As mentioned above, the second clamping claw 113 is provided with a connecting ring 1131, and the second clamping claw 113 is connected to the control device 14 through the connecting ring 1131, so that the construction personnel can directly control the opening and closing of the second clamping claw 113 through the control device 14. Figure 2 As shown;

[0031] Furthermore, a hook 13 is provided on the first clamping claw 111, and the hook 13 is connected to a speed differential anti-fall device 3, and the speed differential anti-fall device 3 is connected to the safety belt 2 through a safety rope 4, and the safety of the device is improved by the speed differential anti-fall device 3.

[0033] Example 2

[0034] This embodiment 2 is a method for using the safety belt suspension device in embodiment 1, and the specific method is as follows:

[0035] When the operator needs to wear a safety belt to climb, the safety belt 2 is first fixed on the operator, and the safety belt 2 is fixed to the clamping device 11 through the safety rope 4 and the speed difference anti-fall device 3. Then, the operator continuously extends the telescopic rod 12, and the clamping device 11 is continuously raised, and the safety rope 4 is pulled out from the speed difference anti-fall device 3 until the clamping device 11 can reach the H-shaped steel beam of the steel structure. After that, the operator holds the bottom of the telescopic rod 12 with one hand, and pulls the control device 14 with the other hand to move. The control device 14 pulls the clamping rod of the clamping device 11 to move, open and close the clamping device 11, and hangs the clamping device 11 on the H-shaped steel beam of the steel structure. Finally, the operator wears the safety belt 2 and starts to climb.

[0036] When the climbing operation is completed, the operator puts on the safety belt 2 and returns to the ground, then holds the bottom of the telescopic rod 12 with one hand and pulls the operating device 14 with the other hand to move, and the operating device 14 is used to pull the clamping device 11 to open and close, and the clamping device 11 can be removed from the safety belt hanging rod or the safety belt hanging ring of the working platform. The safety belt 2 is pre-installed before the climbing operation and then removed after landing, and the safety belt is always hung high and used low during the whole process.
