Description

Technical Field

[0001] This utility model relates to the field of suspended platform detection technology, and in particular to a device for detecting broken ropes inside a suspended platform. Background Technology

[0002] A suspended platform is a type of suspended aerial work platform for personnel. It is typically a platform suspended from the upper part of a building by steel wire ropes along the building's facade, and moves up and down by a motor. Suspended platforms are characterized by strong adaptability to construction, large working height, small footprint, high construction efficiency, convenient erection, and labor savings.

[0003] As a critical component of suspended platforms, wire ropes experience wear and tear due to frequent entanglement during use. To ensure safety, manufacturers typically conduct regular inspections during the after-sales phase and replace them promptly when wear reaches a certain level to prevent wire rope breakage accidents. However, some users, in an effort to save costs, fail to adhere to these regular replacement requirements, significantly increasing the risk of wire rope breakage. Once a wire rope breaks, the suspended platform will lose balance and tilt. Faced with this sudden situation, workers often panic and are unable to quickly stop the platform's ascent or descent, further exacerbating the danger. If measures are not taken promptly, the situation could even lead to the platform overturning, posing a serious threat to the personnel inside.

[0004] Therefore, a rope breakage detection device inside the suspended basket is needed to solve the above problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the above-mentioned rope breakage detection device inside the suspended basket, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a rope breakage detection device inside a suspended platform, which is used to solve the problem that "once the wire rope breaks, the suspended platform will lose balance and tilt. Faced with this sudden situation, the staff often panic and are unable to stop the platform from rising or falling quickly, which further exacerbates the danger. If measures are not taken in time, the situation may even lead to the platform overturning, posing a serious threat to the staff inside."

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rope breakage detection device inside a suspended basket, comprising:

[0009] The main unit includes a suspended basket frame and two wedge-shaped joints. An installation plate is fixedly connected to the suspended basket frame. A steel wire rope is provided at the upper end of each wedge-shaped joint, and a No. 1 pin is provided at the lower end of each wedge-shaped joint. A weight-limiting mechanism is fixedly installed on each suspended basket frame.

[0010] A rope breakage detection mechanism includes a balance plate and a limit switch. The balance plate is rotatably connected to two No. 1 pins. A fixing hole is provided at the center of the balance plate, and a No. 2 pin is rotatably connected in the fixing hole. An upper pull rod is rotatably sleeved on the No. 2 pin. The other end of the upper pull rod is fixedly connected to a weight limiting mechanism. Two detection plates are symmetrically fixedly connected to the upper end of the balance plate.

[0011] As a preferred embodiment of the suspended basket rope breakage detection device of the present invention, the balance plate has two symmetrical connecting holes, and the two No. 1 pins are rotatably connected in the connecting holes.

[0012] As a preferred embodiment of the suspended basket rope breakage detection device of the present invention, wherein: one end of each of the plurality of No. 1 pins is provided with a shaft hole, and a No. 1 snap ring is provided in each of the shaft holes.

[0013] As a preferred embodiment of the suspended basket rope breakage detection device of the present invention, wherein: a limiting hole is provided at one end of the second pin, and a second retaining spring is provided in the limiting hole.

[0014] In a preferred embodiment of the suspended basket rope breakage detection device of this utility model, the limit switch is fixedly installed with the mounting plate, and the trigger head of the limit switch is disposed between the two detection plates.

[0015] In a preferred embodiment of the suspended basket rope breakage detection device of the present invention, a rotating shaft is fixedly connected to the inner sidewall of each of the two wedge-shaped joints, and the wire rope is rotatably sleeved on the rotating shaft.

[0016] The beneficial effects of this utility model are:

[0017] Under normal conditions, the detection plate and limit switch are not in contact due to the action of the wire rope. If one end of the wire rope breaks, the balance plate will lose its balance, causing one end to tilt and thus the detection plate will come into contact with the limit switch. The limit switch will then activate and send a signal to quickly stop the winch motor, thereby quickly stopping the hoisting process. This solves the problem of workers being unable to quickly stop the hoisting process due to panic, allowing workers inside the hoisting to leave and thus protecting them. Attached Figure Description

[0026] Reference Figure 1-Figure 2As one embodiment of this utility model, a rope breakage detection device inside a suspended basket is provided, comprising:

[0027] The main unit 100 includes a suspended basket frame 101 and two wedge joints 103. An installation plate 102 is fixedly connected to the suspended basket frame 101. A wire rope 104 is provided at the upper end of each wedge joint 103, and a first pin 106 is provided at the lower end of each wedge joint 103. A weight-limiting mechanism 105 is fixedly installed on each suspended basket frame 101.

[0028] The rope breakage detection mechanism 200 includes a balance plate 201 and a limit switch 205. The balance plate 201 is rotatably connected to two first pins 106. A fixing hole is opened at the center of the balance plate 201. A second pin 203 is rotatably connected in the fixing hole. An upper pull rod 202 is rotatably sleeved on the second pin 203. The other end of the upper pull rod 202 is fixedly connected to the weight limiting mechanism 105. Two detection plates 204 are symmetrically fixedly connected to the upper end of the balance plate 201.

[0029] Under normal conditions, the detection plate 204 and the limit switch 205 are not in contact due to the action of the wire rope 104. If one end of the wire rope 104 breaks, the balance plate 201 will lose its balance, causing one end to tilt, thus bringing the detection plate 204 into contact with the limit switch 205. The limit switch 205 will then activate and send a signal to quickly stop the winch motor, thereby quickly stopping the hoisting action. This solves the problem that workers cannot quickly stop the hoisting action due to panic, allowing the workers inside the hoisting to leave and thus protecting them.

[0030] The balance plate 201 has two symmetrical connecting holes, and the two No. 1 pins 106 are rotatably connected in the connecting holes, so that the balance plate 201 and the No. 1 pins 106 are rotatably connected.

[0031] Each of the multiple No. 1 pins 106 has a shaft hole at one end, and a No. 1 snap ring 1061 is provided in each shaft hole. The No. 1 snap ring 1061 plays a limiting role in the No. 1 pin 106.

[0032] One end of the second pin 203 has a limiting hole, and a second retaining ring 2031 is installed in the limiting hole. The second retaining ring 2031 plays a limiting role for the second pin 203.

[0033] The limit switch 205 is fixedly installed on the mounting plate 102. The trigger head of the limit switch 205 is located between the two detection plates 204. When the detection plate 204 is tilted, it will come into contact with the trigger head of the limit switch 205.

[0034] The inner walls of the two wedge joints 103 are fixedly connected with rotating shafts, and the wire rope 104 is rotatably sleeved on the rotating shafts, thereby driving the wedge joints 103 to deflect.

[0035] Working principle: Under normal conditions, the detection plate 204 and the limit switch 205 are not in contact due to the action of the wire rope 104. If one end of the wire rope 104 breaks, the balance plate 201 will lose its balance, causing one end to tilt, thus bringing the detection plate 204 into contact with the limit switch 205. The limit switch 205 will then activate and send a signal to quickly stop the winch motor, thereby quickly stopping the hoisting action. This solves the problem of workers being unable to quickly stop the hoisting action due to panic, allowing workers inside the hoisting to leave and thus protecting them. Furthermore, after replacing the broken wire rope 104, the balance plate 201 returns to its balanced state, the limit switch 205 resets, and the restriction is released. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
