[0024] Example 1
[0025] like Figure 1-3 As shown, this embodiment discloses an electric stopping device for elevator traction rope skipping, including a clamping plate assembly and an electric stopping switch. The clamping plate assembly includes a first clamping plate 200 and a second clamping plate 210 arranged in parallel and opposite to each other, and the elevator traction wheel 100 is located between the first clamping plate 200 and the second clamping plate 210. The first clamping plate 200 and the second clamping plate 210 are both provided with bearings, and the central axis of the traction wheel 100 is respectively installed in the bearings on the first clamping plate 200 and the second clamping plate 210. A plurality of annular rope grooves 110 are opened on the outer circumference of the traction wheel 100, and a plurality of traction ropes 120 are respectively installed in the plurality of rope grooves 110.
[0026] In this embodiment, the electrical stop switch includes a first switch 300 and a second switch 400, which are respectively mounted on the outer end surfaces of the first clamping plate 200 and the second clamping plate 210; the first switch 300 and the second switch 400 are connected in series to the safety circuit of the elevator, and when the traction rope 120 is separated from the rope groove 110 of the traction wheel 100, it touches the first switch 300 or the second switch 400, thereby disconnecting the elevator safety circuit, and then controlling the traction wheel 100 to stop rotating.
[0027] Specifically, the first switch 300 includes a first switch body 310 and a first contact 320, and the second switch 400 includes a second switch body and a second contact. The first switch body 310 is mounted on the outer end surface of the first clamping plate 200 and is connected in series to the safety circuit of the elevator through a circuit. The first contact 320 extends from the first switch body 310 toward the traction sheave 100, and its end is close to the wheel surface on one side of the traction sheave 100. The second switch body is mounted on the outer end surface of the second clamping plate 210 and is connected in series to the safety circuit of the elevator through a circuit. The second contact extends from the second switch body toward the traction sheave 100, and its end is close to the wheel surface on the other side of the traction sheave 100. After the traction rope 120 jumps out of the rope groove 110 of the traction sheave 100, it will touch the first contact 320 or the second contact, and the first switch 300 or the second switch 400 will switch from the closed state to the open state, thereby disconnecting the elevator safety circuit, and then controlling the traction sheave 100 to stop rotating.
[0028] like Figure 1As shown, the electric stop switch further includes a first mounting plate 330 and a second mounting plate. The first mounting plate 330 is fixedly mounted on the outer end surface of the first clamping plate 200, and its lower end downwardly exceeds the bottom end of the first clamping plate 200. The first switch 300 is fixedly mounted on the lower end of the first mounting plate 330. The second mounting plate is fixedly mounted on the outer end surface of the second clamping plate 210, and its lower end downwardly exceeds the bottom end of the second clamping plate 210. The second switch 400 is fixedly mounted on the lower end of the second mounting plate. The first switch 300 and the second switch 400 are symmetrically arranged along the traction sheave 100.
[0029] Optionally, in order to ensure that the traction rope 120 can touch the first switch 300 and the second switch 400 after jumping out of the rope groove 110, the distance between the first switch 300, the second switch 400 and the traction sheave 100 should be set within 3-10 mm. In this embodiment, the end of the first contact 320 of the first switch 300 and the end of the second contact of the second switch 400 are both 5 mm away from the traction sheave 100.
[0030] like Figure 1 , 3 As shown, in this embodiment, the elevator traction rope skipping electrical stopping device further includes a radial limiting assembly, which includes a rope blocking rod 500, both ends of which are respectively mounted on the first clamping plate 200 and the second clamping plate 210 through mounting holes on the first clamping plate 200 and the second clamping plate 210, and the rope blocking rod 500 is perpendicular to the first clamping plate 200 and the second clamping plate 210. Specifically, a plurality of rope blocking rods 500 are provided, and the plurality of rope blocking rods 500 are distributed on both sides of the traction sheave 100 in the radial direction, so as to prevent the traction rope 120 from escaping from the rope groove 110 along the radial direction of the traction sheave 100.
[0031] When the elevator car or counterweight is at the bottom, or the elevator is used for a long time and the rope groove 110 is worn, the traction rope 120 may be separated from the rope groove 110 of the traction sheave 100. After the traction rope 120 is separated from the rope groove 110 of the traction sheave 100, the traction rope 120 will overlap the bearing. If no electrical stop switch is provided, the traction sheave 100 will continue to rotate, which may cause the guide wheel and the bearing to deform, or even cause the traction rope 120 to completely separate from the guide wheel.
[0032] The first switch 300 and the second switch 400 of this embodiment can timely detect that the traction rope 120 is separated from the rope groove 110 of the traction sheave 100, thereby controlling the traction sheave 100 to stop rotating, thereby avoiding a more serious situation.
[0033] The first clamping plate 200 and the second clamping plate 210 on both sides of the elevator traction rope skipping electrical arresting device in this embodiment can ensure that the traction rope 120 cannot move along the axial direction of the traction sheave 100 after it is separated from the rope groove 110 of the traction sheave 100. In addition, rope blocking rods 500 are provided on both sides of the radial direction of the traction sheave 100, and the rope blocking rods 500 can effectively prevent the traction rope 120 from being separated from the rope groove 110 along the radial direction of the traction sheave 100. And the first switch 300 and the second switch 400 on both sides can timely control the traction sheave 100 to stop rotating after monitoring that the traction rope 120 is separated from the rope groove 110 of the traction sheave 100, thereby effectively avoiding major safety accidents.
[0034] The elevator traction rope skipping electrical stopping device in this embodiment combines the traction rope anti-jumping device with the electrical stopping switch, thereby improving the safety factor of the elevator operation and providing dual protection for the elevator.
[0035] Example 2
[0036] This embodiment discloses a safety elevator, including a car, a traction sheave 100, a traction rope 120, and also includes the elevator traction rope skipping electrical stopping device in Example 1. The traction sheave 100 is rotatably mounted on a first clamping plate 200 and a second clamping plate 210 through a bearing, and the traction rope 120 is installed in a rope groove 110 of the traction sheave 100, and its end is connected to the car.
[0037] In this embodiment, the traction sheave 100 rotates to drive the traction rope 120 to move, thereby driving the car to move up and down in the floor. The first switch 300 and the second switch 400 are respectively provided on both sides of the axial direction of the traction sheave 100. The first switch 300 and the second switch 400 are used to monitor the traction rope 120 after it is separated from the rope groove 110 of the traction sheave 100 and control the elevator safety circuit to be disconnected, thereby controlling the elevator to stop moving, thereby improving the safety performance of the elevator. The rope blocking rods 500 on both sides of the radial direction of the traction sheave 100 can effectively prevent the traction rope 120 from being separated from the rope groove 110 along the radial direction of the traction sheave 100.
[0038] The safety elevator in this embodiment can effectively prevent the traction rope 120 from being separated from the rope groove 110 of the traction sheave 100, thereby ensuring the running stability of the elevator. Even if the traction rope 120 is separated from the rope groove 110 of the traction sheave 100, the first clamping plate 200 and the second clamping plate 210 on the axial side and the rope blocking rod 500 on the radial side can effectively limit the position of the traction rope 120, ensuring that the traction sheave 100 and the traction rope 120 will not be completely separated. Moreover, when the traction rope 120 touches the first switch 300 or the second switch 400, the elevator safety circuit will be disconnected and the elevator will stop running, thereby effectively avoiding the wear of the bearing and the traction rope 120 and the damage of other components.
[0039] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
