The application scenario of the suspension platform provided by the present invention is first described with reference to fig. 1. As shown in fig. 1, the suspension platform comprises a suspension bracket assembly 100 and a hanging basket 200, the suspension bracket assembly 100 is disposed on the top of the building 001, and the hanging basket 200 is suspended on the suspension bracket assembly 100 and can carry workers or goods to lift and lower along the elevation of the building 001.

In order to avoid the suspension platform from overloading to cause danger, the embodiment of the present invention provides a suspension platform that can include an overload detection device. As shown in fig. 2, 3 and 4, the overload detecting device 201 is disposed on the basket 200. The overload detecting device 201 includes an elastic element 212, an overload detecting element 215, and a first detected element 214. The elastic member 212 can bear the weight of the basket 200 and is elastically deformed. When the elastic element 212 is elastically deformed, the overload detecting element 215 can move relative to the first detected element 214 along with the elastic deformation of the elastic element 212, and the first detected element 214 is disposed on a moving path of the overload detecting element 215, that is, a distance between the first detected element 214 and the overload detecting element 215 varies along with the amount of the elastic deformation of the elastic element 212.

As the weight of the worker or the goods loaded in the gondola 200 increases, the amount of elastic deformation of the elastic member 212 gradually increases, and the overload detecting member 215 moves accordingly with a gradually decreasing interval from the first detected member 214. When the weight of the worker or the cargo loaded in the basket 200 exceeds the rated load of the suspended platform, for example, when the weight of the basket 200 exceeds 25% of the rated load, the overload detecting element 215 can detect the first detected element 214, and then the overload detecting element 215 sends a signal to the electric control system of the suspended platform, and the electric control system receives the signal, controls the lifting motor of the suspended platform to stop running, and can activate the alarm device to give an alarm. Like this, can accurately detect when the personnel or the goods weight that suspend platform carried in midair surpass rated load and suspend the platform and overload to can in time warn the staff and suspend the platform in midair and overload, avoid causing because of overloading and suspend the platform and take place danger.

The alarm device may be a buzzer, an audible and visual alarm, and the like, and is not limited specifically herein.

As shown in fig. 1 and 2, the gondola 200 comprises an end cradle 203 and the suspended platform further comprises a lift motor 209. End hangers 203 are installed at both ends of the basket 200, and a lifting motor 209 is installed on the end hangers 203 for lifting the basket 200. Specifically, the upper end of the working steel wire rope 020 is fixed on the suspension bracket assembly 100, and when the suspension platform operates, the friction force between the lifting motor 209 and the working steel wire rope 020 can drive the hanging basket 200 to ascend or descend along the vertical surface of the building 001. The lifting motor 209 may be an asynchronous motor, a synchronous motor, a stepping motor, a servo motor, etc., and the specific type and model may be selected according to the requirement, which is not specifically limited herein.

The lift motor 209 may be slidably connected to the end hanger 203 such that the lift motor 209 is capable of moving in a vertical direction relative to the end hanger 203 and the lift motor 209 is not capable of moving in a horizontal direction relative to the end hanger 203.

In one embodiment, as shown in fig. 5, the end hanger 203 may be provided with a fixing hole 216, and a bolt 217 passes through the fixing hole 216 to connect the lifting motor 209 to the end hanger 203. It should be noted that the size of the fixing hole 216 is larger than the size of the bolt 217, so that the bolt 217 can slide up and down in the fixing hole 216 in the vertical direction, thereby enabling the lift motor 209 to move in the vertical direction with respect to the end hanger 203.

In another embodiment, a slide rail with two closed ends may be disposed on the contact surface of the end hanger 203 and the lifting motor 209 along the vertical direction, a slide block is mounted in the slide rail, and the slide block is mounted on the lifting motor 209, so that the motor 209 can also slide in the vertical direction relative to the end hanger 203.

As shown in fig. 4, one end of the elastic member 212 is connected to the end hanger 203, and the other end of the elastic member 212 is connected to the lifting motor 209, in which case the lifting motor 209 slides with respect to the end hanger 203, and the basket 200 and the lifting motor 209 can apply force to the elastic member 212 at both ends of the elastic member 212, respectively, to elastically deform the elastic member 212. Thus, the elastic element 212 can be elastically deformed differently according to the weight of the basket 200, so that the overload of the basket 200 can be accurately detected in time.

As shown in fig. 4, the overload detecting apparatus 201 further includes an elastic member fixing bracket 211 and a connecting member 213. The elastic member fixing bracket 211 is fixedly connected to the end hanger 203 by welding or bolting. The overload detecting element 215 is fixedly connected to the elastic element fixing bracket 211, and one end of the connecting member 213 is connected to the lifting motor 209, and the other end is connected to the first detected element 214. The connection 213 and the elastic member fixing bracket 211 press the elastic member 212 so that the basket 200 applies a vertically downward pressure to the elastic member 212 through the end hanger 203 and the elastic member fixing bracket 211, and the lift motor 209 applies a vertically upward pressure to the elastic member 212 through the connection 213 to elastically deform the elastic member 212. The elastic element 212 may be an elastic element such as a compression spring, a torsion spring, a belleville spring, or rubber, and is not limited herein.

Specifically, when the weight carried by the basket 200 is lower than the rated load, the end hanger 203 and the elastic element fixing bracket 211 exert a small pressure on the elastic element 212, in which case the elastic deformation amount of the elastic element 212 is small, and the distance between the overload detecting element 215 connected to the elastic element fixing bracket 211 and the first detected element 214 connected to the connecting member 213 is large, so that the overload detecting element 215 cannot detect the first detected element 214. As the weight carried by the hanging basket 200 increases, the pressure applied by the end portion hanger 203 and the elastic element fixing bracket 211 to the elastic element 212 gradually increases, the elastic deformation amount of the elastic element 212 also increases, the distance between the overload detecting element 215 connected to the elastic element fixing bracket 211 and the first detected element 214 connected to the connecting part 213 becomes smaller and smaller, and further, when the weight carried by the hanging basket 200 exceeds the rated load, the distance between the overload detecting element 215 and the first detected element 214 is shortened to the extent that the overload detecting element 215 can detect the first detected element 214, so that the alarm can be given in time and the operation of the hanging platform can be stopped when the hanging platform is overloaded.

As shown in fig. 4, in an embodiment, the elastic element 212 may be a compression spring, the connecting element 213 may be a bolt, the elastic element fixing support 211 is a cylinder structure with an opening at one end and an opening at the bottom surface of the other end, the cylinder structure may buckle the compression spring, and a screw of the bolt penetrates through the compression spring and is connected to the lifting motor 209 through the opening of the cylinder structure, so that the opening bottom surface of the cylinder structure and a nut of the bolt can squeeze the compression spring, the elastic element fixing support 211 with the cylinder structure can limit a movement range of the compression spring when the compression spring is elastically deformed, and is convenient to detach and mount, and can facilitate adjustment and maintenance of the overload detection apparatus 201.

In another embodiment, the elastic member 212 may be a tension spring. In this case, one end of the tension spring is fixedly connected to the bottom of the lift motor 209 and the other end is fixedly connected to the elastic member fixing bracket 211, so that the basket 200 applies a vertically downward tension to the tension spring through the end hanger 203 and the elastic member fixing bracket 211, and the lift motor 209 applies a vertically upward tension to the tension spring, so that the tension spring is elastically deformed, that is, the length of the tension spring is elongated. The larger the weight of the hanging basket 200 carrying the articles is, the longer the tension spring is pulled, the closer the distance between the overload detecting element 215 connected to the elastic element fixing bracket 211 and the first detected element 214 connected to the connecting part 213 is, and further when the weight of the hanging basket 200 carrying the articles exceeds the rated load, the overload detecting element 215 can detect the first detected element 214, alarm in time and stop the operation of the suspended platform.

The overload detecting element 215 may be a contact sensor, such as a micro switch or a pressure sensitive switch, and when the weight of the articles carried by the gondola 200 exceeds the rated load, the first detected element 214 will contact the contact sensor, so as to trigger the contact sensor, and the contact sensor will send a signal to the electric control system of the suspension platform, so that the electric control system controls the lifting motor 209 to stop running, and starts the alarm device to give an alarm; alternatively, the overload detecting element 215 may be a proximity sensor, such as a capacitive proximity sensor or an inductive proximity sensor, when the weight of the articles carried by the basket 200 exceeds the rated load, the first detected element 214 will be in the detection range of the proximity sensor, and trigger the proximity sensor, and the proximity sensor will send a signal to the electronic control system of the suspended platform, so that the electronic control system controls the lifting motor 209 to stop running, and starts the alarm device to give an alarm.

The number of the overload detection devices 201 is not particularly limited. For example, the suspension platform may include 2 overload detecting devices 201 respectively installed at the middle portions of both ends of the gondola 200; for another example, it is feasible that the suspended platform may include 4 overload detecting devices 201, which are respectively installed at four corners of the hanging basket 200.

As shown in fig. 1 and 2, in some embodiments of the present invention, the suspension platform may further include a limit detection device 202 and a second detected element 030. As shown in fig. 6, the limit detector 202 is provided on the basket 200, for example, the limit detector 202 may be mounted on the end hanger 203. Thus, the limit detector 202 can move along with the basket 200 when the basket 200 is lifted along the facade of the building 001. The second detected element 030 is arranged on the moving path of the limit detecting device 202, so that the second detected element 030 can be detected when the limit detecting device 202 moves to the second detected element 030, then the limit detecting device 202 can send a signal to the electronic control system of the suspended platform, and the electronic control system can control the lifting motor 209 to stop operating after receiving the signal, thereby stopping the upward movement of the hanging basket 200.

As shown in fig. 7, the limit detection device 202 includes a first limit detection element 221 and a second limit detection element 222. The first limit detecting element 221 and the second limit detecting element 222 move along with the hanging basket 200, and the second detected element 030 is disposed on a moving path of the first limit detecting element 221 and the second limit detecting element 222, so that the first limit detecting element 221 and the second limit detecting element 222 can respectively detect the second detected element 030 during the process that the limit detecting device 202 moves along with the hanging basket 200. When the first limit detecting element 221 or the second limit detecting element 222 detects the second detected element 030, the first limit detecting element 221 or the second limit detecting element 222 can send a signal to an electric control system of the suspension platform, and the electric control system can control the lifting motor 209 to stop running after receiving the signal, so that the hanging basket 200 stops moving. Thus, the moving range of the gondola 200 can be restricted, preventing the danger of the gondola 200 rising too high.

When the limit detection device 202 moves to the second detected element 030, the first limit detection element 221 can detect the second detected element 030 before the second limit detection element 222. Thus, when the first limit detecting element 221 detects the second detected element 030, a signal can be sent to the electronic control system to stop the lifting of the hanging basket 200, and when the first limit detecting element 221 fails, the second limit detecting element 222 can detect the second detected element 030 to send a signal to the electronic control system to stop the movement of the hanging basket 200, so that double protection can be realized, and the hanging basket 200 can still be automatically controlled to stop moving when the first limit detecting element 221 fails.

When the first limit detection element 221 detects that the second detected element 030 sends a signal to the electronic control system to stop the lifting of the basket 200, the first limit detection element 221 is effective, and at this time, the basket 200 can be lowered although the basket cannot be lifted; when the second limit detection element 222 detects that the second detected element 030 sends a signal to the electronic control system to stop the movement of the hanging basket 200, it is described that the first limit detection element 221 fails, the first limit detection element 221 is likely to fail, the hanging basket 200 cannot ascend or descend at the moment, the worker needs to overhaul the first limit detection element 221, and the hanging basket 200 can continue to operate after the failure is eliminated.

Specifically, as shown in fig. 1, the second detected element 030 may be installed on the working wire 020 above the basket 200 near the hanging bracket assembly 100. As shown in fig. 6 and 7, the limit detection device 202 is mounted on the end hanger 203 adjacent to the lift motor 209. The basket 200 ascends along the working wire rope 020 through the friction force between the lifting motor 209 and the working wire rope 020, and the limit detection device 202 moves close to the working wire rope 020, so that when the limit detection device 202 moves to the installation position of the second detected element 030, the first limit detection element 221 can detect the second detected element 030 before the second limit detection element 222, and a signal is transmitted to the electronic control system to stop the lifting of the basket 200. When the first limit detecting element 221 fails, the second limit detecting element 222 can detect the second detected element 030, and transmits a signal to the electronic control system to stop the lifting of the basket 200.

In one embodiment, the position limit detection device 202 further comprises a support arm 223. As shown in fig. 7, the bottom of the support arm 223 is connected to the basket 200, and in particular, the bottom of the support arm 223 may be connected to the end hanger 203 by a bolt, which facilitates the installation and removal of the limit detector 202. The first limit detecting element 221 and the second limit detecting element 222 are mounted on the top of the supporting arm 223, and in particular, the top of the supporting arm 223 may be provided with a mounting seat for mounting the first limit detecting element 221 and the second limit detecting element 222.

The first and second limit detection elements 221 and 222 may be touch sensors, such as micro switches, roller type travel switches, or proximity sensors, such as capacitive proximity switches or inductive proximity switches.

Specifically, the first limit detection element 221 and the second limit detection element 222 may be both contact sensors or both proximity sensors; alternatively, one of the first limit detecting element 221 and the second limit detecting element 222 may be a touch sensor, and the other may be a proximity sensor.

In the first case: the first limit detecting element 221 and the second limit detecting element 222 are both touch sensors. The first limit detecting element 221 and the second limit detecting element 222 may be the same type of touch sensor, and in this case, the distance between the installation position of the first limit detecting element 221 and the second detected element 030 is smaller than the distance between the installation position of the second limit detecting element 222 and the second detected element 030, so that it can be ensured that the first limit detecting element 221 detects the second detected element 030 before the second limit detecting element 222. Alternatively, the first limit detecting element 221 and the second limit detecting element 222 may be different touch sensors, for example, as shown in fig. 7, the first limit detecting element 221 may be a roller type travel switch, the second limit detecting element 222 may be a micro switch, and a distance between a roller of the roller type travel switch and the second detected element 030 is smaller than a distance between a trigger point of the micro switch and the second detected element 030. In this way, it can be ensured that the first limit detecting element 221 detects the second detected element 030 before the second limit detecting element 222, and since the swing arm of the roller type travel switch can swing along with the rolling of the roller, it can be ensured that the second limit detecting element 222 is triggered when the roller type travel switch fails, and the structure of the limit detecting device 202 is not damaged.

In the second case: the first limit detection element 221 and the second limit detection element 222 are both proximity sensors. In this case, the detection range of the first limit detection element 221 may be larger than that of the second limit detection element 222, which can ensure that the first limit detection element 221 detects the second detected element 030 before the second limit detection element 222, and since a proximity sensor is used, it is not necessary to contact the second detected element 030, so that the second limit detection element 222 can be triggered when the first limit detection element 221 fails without damaging the structure of the limit detection device 202.

In a third case: the first limit detecting element 221 is a touch sensor, and the second limit detecting element 222 is a proximity sensor. In this case, when the first limit detecting element 221 contacts the second detected element 030, the distance between the second limit detecting element 222 and the second detected element 030 is greater than the detection range of the second limit detecting element 222, so that it can be ensured that the first limit detecting element 221 detects the second detected element 030 earlier than the second limit detecting element 222.

In a fourth case: the first limit detecting element 221 is a proximity sensor, and the second limit detecting element 222 is a touch sensor. In this case, when the first limit detecting element 221 detects the second detected element 030, the second limit detecting element 222 does not contact the second detected element 030 yet, so that it can be ensured that the first limit detecting element 221 detects the second detected element 030 before the second limit detecting element 222, and the second limit detecting element 222 can be triggered when the first limit detecting element 221 fails without damaging the structure of the limit detecting device 202.

The number of the limit detection devices 202 is not particularly limited, and may be 1 or more. For example, the suspension platform may include 1 limit detection device 202, which may be disposed on an end hanger 203 at any one end of the two ends of the basket 200; alternatively, the suspension platform may comprise 2 limit detection devices 202 symmetrically arranged on the end hangers 203 at both ends of the basket 200, which is all feasible.

As shown in fig. 8, the suspension bracket assembly 100 includes a front bracket 102, a cross member 101, a rear bracket 105, and a support beam 104. The cross member 101 has one end fixed to an upper end of the front bracket 102 and the other end fixed to an upper end of the rear bracket 105, and the front bracket 102 and the rear bracket 105 can be used to support the upper cross member 101.

As shown in fig. 1, the gondola 200 is connected to the beam 101 at one end adjacent to the facade of the building 001 by means of working cables 020. The beam 101 is subjected to a tensile force applied by the basket 200, and in order to prevent the beam 101 from deforming due to a force, which may cause the front bracket 102 and the rear bracket 105 to displace, which may cause a risk of destabilization of the suspension platform structure, a support beam 104 may be provided on the suspension bracket assembly 100. As shown in fig. 8, the two ends of the support beam 104 are respectively connected to the front bracket 102 and the rear bracket 105, so that the distance between the front bracket 102 and the rear bracket 105 can be controlled, the front bracket 102 and the rear bracket 105 can be prevented from being displaced, and the strength and stability of the suspension bracket assembly 100 can be improved.
