Description
Technical Field
The invention relates to the field of rescue equipment of a gearless traction type elevator, in particular to an emergency control device integrating opening, closing and traction of an elevator.
Background
When the traction type elevator is in use, the situation of failure and shutdown is difficult to avoid, after the failure occurs, the operation needs to be carried out from the outside of an elevator shaft, and the leveling is realized by opening a brake of a traction machine, so that passengers can be released. However, when the mass on the car side and the mass on the counterweight side approach balance, there is a case where the car cannot move upward or downward even if the hoisting machine brake is opened. At the moment, the balance of two sides needs to be broken by adopting a certain mode, and the elevator car is driven to move by applying an acting force from the outside. In the current industry field, the modes for realizing the two functions are mainly divided into a mechanical mode and an electrical mode, and one of common failure reasons of the elevator is circuit interruption, so that the mechanical mode is more favored by the industry compared with the electrical rescue equipment which relies on an additional power supply and control to realize rescue operation.
The problem is that the two steps of releasing the band-type brake and pulling the cage to move in the existing rescue equipment are separated from the operation equipment, and the operation is difficult for a single person. In addition, in the process of controlling the movement of the car after the band-type brake is released, the system resistance and the mass of the car and the counterweight on two sides can be changed, and the car is out of control and accelerated. If the rescue workers cannot timely contact the contracting brake and switch the contracting brake into the contracting state, the lift car is out of control and rapidly ascends or descends, and passengers in the lift car are in danger of life.

Two transmission modules are successively arranged on the movement stroke of the handle 2 and are respectively in transmission connection with the contracting brake opening and closing switch and the car traction device, so that two different control operations can be carried out through one handle, the contracting brake does not need to be released on one device firstly, and then the car is driven to move on the other device, and the control flexibility and the response time are improved. Meanwhile, the release of the band-type brake is arranged on the first stroke 21 which is passed by the handle firstly, so that the situation that the sequence of releasing the band-type brake firstly and then pulling the lift car is not reversed and staggered is ensured.
As an embodiment, the device further comprises a one-way transmission device, and the handle 2 is in transmission connection with the second displacement conversion device 12 through the one-way transmission device.
In one embodiment, the one-way transmission device is a one-way bearing, and the handle 2 and the second displacement device 12 are in transmission connection through the one-way bearing.
In one embodiment, the one-way transmission device is a ratchet wheel, and the handle 2 and the second displacement transmission device 12 are connected through the ratchet wheel.
Because the second displacement conversion device 12 is in transmission connection with the handle 2 through the one-way transmission device, when the handle 2 reciprocates in the second stroke 22, the second displacement conversion device 12 only receives the movement of the handle 2 in one direction and converts the displacement of the handle 2, and when the handle 2 reversely moves, because the one-way transmission device does not transmit the movement, the second displacement conversion device 12 does not transmit the reverse movement, thereby ensuring the accumulation of the displacement.
Referring to fig. 1, as an embodiment, the device further includes a reset device 3, the reset device 3 is in transmission connection with the handle 2, and is used for automatically moving the handle 2 back to the initial position in a natural state.

As an example, a damping stroke is further included, which is provided between the first stroke 21 and the second stroke 22.
A buffer stroke is arranged between the first stroke 21 and the second stroke 22, so that a certain vacant interval is formed in the rotation process of the handle 2, and the problem that the handle is difficult to control and even breaks down due to the fact that the handle 2 controls the band-type brake and the traction device simultaneously due to errors in the installation structure is avoided.
Referring to fig. 1-3, as an embodiment, the device further includes a first cam 41 and a second cam 42; the axes of the first cam 41 and the second cam 42 are coincided with the fixed points around when the handle 2 rotates, and both the first cam 41 and the second cam 42 are in transmission connection with the handle 2; when the handle 2 is located at the first stroke 21, the first cam 41 pushes the brake on-off switch to move, and when the handle 2 is located at the second stroke 22, the second cam 42 pushes the car traction device to move.
As shown in fig. 1 to 3, when the handle is rotated, the handle is in the first stroke 21, the first cam 41 compresses the first displacement conversion device 11, and transmits the motion to the brake on-off switch through the first displacement conversion device 11, so that the brake is released. As the handle continues to rotate into the second stroke 22, the second cam 42 compresses the second translation device 12 and transfers that motion to car traction device motion through the second translation device 12. The handle 2 then reciprocates within the second stroke 22, and because the handle 2 is in driving connection with the second displacement transformation device 12 through the one-way transmission device, the motion of the handle 2 when returning is not transmitted to the second displacement transformation device 12, so that the car can be pulled to move through the repeated swinging of the handle 2.
Referring to fig. 4-6, as an embodiment, the second stroke 22 is provided with a branch at the connection with the first stroke 21, the first shift converter 11 is provided at two sides of the branch, the stroke is divided into an ascending stroke 221 and a descending stroke 222, the handle 2 draws the car to ascend when swinging within the ascending stroke 221, and the handle 2 draws the car to descend when swinging within the descending stroke 222.
Sometimes the car stops closer to the upper exit and sometimes stops closer to the lower exit. In the traction process, the control of the ascending or descending of the lift car is selected according to the actual situation of the lift car, so that the lift car can be moved to a proper position more quickly, and the rescue time is shortened.
Referring to fig. 4-6, as an embodiment, the ball joint further includes a ball pivot 6 and a limiting plate 5; the handle 2 is movably connected with the ball head rotating shaft 6 and moves by taking the ball head rotating shaft 6 as a fulcrum; the limiting plate 5 is provided with a Y-shaped stroke clamping groove 51, the handle 2 penetrates through the limiting plate 5 to move in the stroke clamping groove 51, the lower end of the Y shape is a first stroke 21, and the upper end of the Y shape is forked into an upward stroke 221 and a downward stroke 222 respectively.
The handle 2 takes the ball head rotating shaft 6 as a rotating fulcrum, can move transversely except for longitudinal movement, has larger moving space, and can realize various different operations. The movement track is limited by combining the stroke clamping groove 51, and effective control on the opening, closing and traction of the band-type brake can be guaranteed.
When the handle 2 moves in the stroke slot 51, the handle can only move towards the side due to the limit relationship of the stroke slot 51, so that the transverse displacement is generated, and the first displacement conversion device 11 is extruded, so that the internal contracting brake is released. The handle 2 moves continuously, enters an ascending stroke 221 or a descending stroke 222 at the bifurcation as required, reciprocates in the stroke, transmits the motion to the second displacement conversion device 12 through the one-way transmission device, accumulates displacement and realizes traction on the car.
