[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figs. 1 to 4 A weight-limiting safety device for construction includes a weight-limiting block 1, a locking block 2, a telescopic cylinder 3, a positioning component 4, and a pressure sensor 5. The locking block 2 is located above the weight-limiting block 1, and there is a gap between the weight-limiting block 1 and the locking block 2 for the suspended platform wire rope 6 to pass through. The pressure sensor 5 is located on the weight-limiting block 1. When the suspended platform wire rope 6 comes into contact with the pressure sensor 5, the pressure sensor 5 can sense and monitor the pressure of the suspended platform wire rope 6 on the pressure sensor 5 in real time, thereby determining the corresponding tension of the suspended platform wire rope 6, i.e., the weight of the load being lifted by the suspended platform. The telescopic cylinder 3 is located on the weight-limiting block 1, and its telescopic end is connected to the locking block 2. It can drive the locking block 2 to move towards the weight-limiting block 1, thereby clamping and locking the suspended platform wire rope 6. The positioning component 4 is located on the weight-limiting block 1 and connected to the locking block 2, and can limit the relative movement between the weight-limiting block 1 and the locking block 2.

[0026] This device, by installing a pressure sensor 5 on the weight-limiting block 1, can monitor the pressure of the suspended platform wire rope 6 on the pressure sensor 5 in real time, thereby determining the corresponding tension of the suspended platform wire rope 6 (the relationship between the tension of the suspended platform wire rope and the pressure of the suspended platform wire rope on the pressure sensor can be obtained in advance through loading experiments), i.e., the weight of the load being lifted by the suspended platform. This allows operators to be aware of the specific situation in a timely manner and choose whether to continue lifting to avoid overloading, effectively reducing the occurrence of safety accidents. By installing a telescopic cylinder 3, when the lifting weight exceeds the limit, the telescopic cylinder 3 can drive the locking block 2 to move towards the weight-limiting block 1, thereby clamping and fixing the suspended platform wire rope 6 with the weight-limiting block 1, thus stopping the movement of the suspended platform wire rope 6. By installing a positioning component 4, movement between the weight-limiting block 1 and the locking block 2 can be further prevented, further enhancing the safety of construction.

[0027] Specifically, the weight limiting block 1 is further provided with support rods, and the locking block 2 is slidingly installed on the support rods. In the embodiment, the number of the support rods is two, and the two support rods are respectively arranged at the two ends of one side of the weight limiting block 1. By arranging the support rods, the locking block 2 can be effectively supported. In this way, when the telescopic cylinder 3 pulls the locking block 2, the locking block 2 moves in a specified direction under the limiting of the support rods, effectively ensuring that the locking block 2 cooperates with the weight limiting block 1 to clamp and fix the wire rope 6 of the hanging basket.

[0028] Specifically, the weight limiting block 1 is further provided with support rods, and the locking block 2 is slidingly installed on the support rods. In the embodiment, the number of the support rods is two, and the two support rods are respectively arranged at the two ends of one side of the weight limiting block 1. By arranging the support rods, the locking block 2 can be effectively supported. In this way, when the telescopic cylinder 3 pulls the locking block 2, the locking block 2 moves in a specified direction under the limiting of the support rods, effectively ensuring that the locking block 2 cooperates with the weight limiting block 1 to clamp and fix the wire rope 6 of the hanging basket.

[0029] Specifically, the positioning assembly 4 comprises a sliding rail 41, a pull rod 42 and a pair of positioning blocks 43. The sliding rail 41 is arranged on the weight limiting block 1, the pull rod 42 is installed on the locking block 2 and connected with the sliding rail 41, and the pair of positioning blocks 43 are slidingly installed at the two ends of the sliding rail 41. In addition, the weight limiting block 1 is provided with two slide openings 11, and the pair of positioning blocks 43 are respectively provided with sliding shafts 44 extending into the two slide openings 11. In this way, when the locking block 2 needs to be pulled to move towards the positioning blocks 43 to be locked, at this time, the telescopic cylinder 3 pulls the locking block 2 to move, and at the same time, the pull rod 42 pushes the sliding rail 41 to move. Under the limiting of the slide openings 11 and the sliding shafts 44, the pair of positioning blocks 43 abut against each other to realize positioning.

[0030] Specifically, the slide openings 11 are in an inverted eight-shaped type. In this way, when the locking block 2 moves towards the weight limiting block 1, the pair of positioning blocks 43 can abut against each other; and when the locking block 2 moves away from the weight limiting block 1, the pair of positioning blocks 43 can be separated from each other.

[0031] Specifically, the length of the sliding rail 41 is the same as the length of the weight limiting block 1. In this way, the pair of positioning blocks 43 have sufficient sliding stroke. Of course, in the present application, the length of the sliding rail 41 can also be less than the length of the weight limiting block 1 according to actual conditions and specific requirements, which is not limited herein.

[0032] Specifically, one of the positioning blocks 43 is provided with a positioning groove 45, and the other positioning block 43 is provided with a positioning tooth 46, and the positioning tooth 46 is connected with the positioning groove 45. In this way, when the two positioning blocks 43 abut against each other, the positioning groove 45 and the positioning tooth 46 can be connected at this time, so that the movement between the weight limiting block 1 and the locking block 2 can be further avoided, and the safety of construction is further enhanced.

[0033] Specifically, the pressure sensor 5 is provided with a wireless communication module, and the monitoring signal can be fed back to an external controller through the wireless communication module, and the external controller controls whether the telescopic cylinder 3 needs to lock the hanging basket steel wire rope 6 according to the signal of whether overweight. Specifically, the wireless communication module can be a Bluetooth module, a WIFI module, a GPRS module, etc., which is not limited here.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application.
