Description

Technical Field

[0001] This invention relates to the field of construction technology for duplex elevators, and in particular to a method, device, computer equipment, and storage medium for controlling the length of telescopic beams in duplex elevators. Background Technology

[0002] When using a duplex elevator, the position of the telescopic beam needs to be adjusted to accommodate different floors, involving the extension and retraction of the beam. Traditionally, a pull rope connected to a microswitch is used to detect and limit the beam's travel. However, in practice, significant impact forces occur at the end of extension and retraction. If the moving end of the beam touches a worker, it can cause serious personal injury. Furthermore, due to the complex operating environment, the pull rope may snag on foreign objects during extension. Consequently, if the microswitch is triggered before the beam reaches the preset length, lowering the beam at this point poses a risk of the equipment falling, potentially leading to accidents and property damage. Summary of the Invention

[0003] The purpose of this invention is to provide a method, device, computer equipment, and storage medium for controlling the length of a telescopic beam in a multi-level elevator, so as to alleviate the technical problem of safety hazards in telescopic beam length control.

[0006] Determine the preset length value at the location of the telescopic beam;

[0007] Control the extension of the telescopic beam when the actual length of the telescopic beam is less than the preset length value;

[0008] When the actual length of the telescopic beam is greater than or equal to the preset length value, obtain whether there is a signal in the support below the telescopic beam;

[0009] If there is a support under the telescopic beam, a normal working status signal will be generated.

[0010] If there is no support under the telescopic beam, an abnormal working status signal will be generated.

[0011] In conjunction with the first aspect, the present invention provides a first possible implementation of the first aspect, wherein the step of controlling the elongation of the telescopic beam includes:

[0012] To determine whether there are obstacles along the extension path of the telescopic beam;

[0013] If there are no obstacles in the extension path, the telescopic beam will be controlled to extend to the preset length value.

[0014] If there is an obstacle on the extension path, obtain the distance between the telescopic beam and the obstacle;

[0015] When the distance between the telescopic beam and the obstacle is greater than a threshold, the telescopic beam is controlled to reduce its extension speed.

[0016] When the distance between the telescopic beam and the obstacle is less than or equal to the threshold and greater than zero, the telescopic beam is controlled to decelerate at a preset deceleration until it stops extending.

[0017] When the telescopic beam touches the obstacle, the telescopic beam will immediately stop extending or retracting.

[0018] In conjunction with the first possible implementation of the first aspect, the present invention provides a second possible implementation of the first aspect, wherein when the distance between the telescopic beam and the obstacle remains constant for a preset time and the telescopic beam continues to extend or retract for a preset time, a distance sensor fault signal is generated, and the telescopic beam is controlled to stop extending or retracting.

[0020] When there is a support under the telescopic beam, determine whether the telescopic beam is supported by the support.

[0021] If the telescopic beam is supported by the support structure, then the telescopic beam is prohibited from extending or retracting.

[0023] With a support structure under the telescopic beam, measure the overlap dimension of the telescopic beam and the support structure on the vertical projection plane.

[0024] If the overlapping dimension is smaller than the preset support surface dimension, the telescopic beam will continue to extend.

[0025] If the overlapping dimension is greater than or equal to the preset support surface dimension, the telescopic beam will stop extending.

[0026] Secondly, the telescopic beam length control device provided by the present invention includes:

[0027] Telescopic beam detection device, used to detect the actual location and length of telescopic beams;

[0028] Support detection device, used to detect whether there is a support under the telescopic beam;

[0037] The embodiments of this invention bring the following beneficial effects: When controlling the length of the telescopic beam, a preset length value at the location of the telescopic beam can be determined based on its position, and its extension and retraction can be controlled in combination with the actual length of the telescopic beam. It can also detect whether there are supports under the telescopic beam, thereby generating corresponding working status signals. This can remind workers or coordinate the operation of the telescopic beam hoisting equipment, avoiding the release of the beam without support, and improving equipment safety.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0044] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figure 1 As shown, the method for controlling the length of a telescopic beam in a multi-level elevator provided by this embodiment of the invention includes the following steps:

[0046] Step S0001: Obtain the location and actual length of the telescopic beam. In step S0001, the location of the telescopic beam can be detected by an encoder mounted on the motor that drives the telescopic beam to change position, or by an external photoelectric or ultrasonic position sensor. The actual length of the telescopic beam can be obtained by converting the test value of a distance sensor installed on the telescopic beam, or by calculating it according to a corresponding ratio using an external camera to capture images.

[0047] Step S0002: Determine the preset length value at the location of the telescopic beam. In step S0002, the preset length value can be set according to the hoistway or the structural components supporting the telescopic beam. In other words, when the telescopic beam is hoisted to change its floor position, the space corresponding to each floor position may differ. Therefore, the maximum elongation dimension of the telescopic beam at different height positions can be preset as the preset length value. Alternatively, the minimum elongation dimension of the telescopic beam can be used as the preset length value based on the position of the components supporting the telescopic beam at each height position, provided that the support can stably support the telescopic beam.

[0048] Step S0003: When the actual length of the telescopic beam is less than the preset length value, control the telescopic beam to extend, so that the actual length of the telescopic beam can gradually approach the preset length value until the preset requirement is met.

[0049] Step S0004: When the actual length of the telescopic beam is greater than or equal to a preset length value, obtain a signal indicating the presence or absence of a support beneath the telescopic beam. Detecting the presence or absence of a support signal provides a basis for determining whether the telescopic beam can be safely released, thus preventing accidents and property damage caused by blindly releasing the telescopic beam without support. The presence or absence of a support signal can be detected using photoelectric sensors, electromagnetic sensors, or ultrasonic sensors. The main technical means lies in detecting whether there is a support below the supported position at the movable end of the support beam, and whether the supporting surface of the support relative to the supported position is sufficiently large as a basis for judgment. It should be noted that if the sensor detects an object below the supported position at the movable end of the support beam, but the surface area of ​​the object relative to the supported position is smaller than a preset area, it can still be determined that there is no support, thus avoiding the impact of an excessively small supporting surface on the stability of the telescopic beam.

[0050] Step S0005: If there is a support under the telescopic beam, a normal working status signal is generated; wherein, the normal working status signal can be used as a control condition for the sound and light generating device. When the normal working status signal is generated, the sound and light generating device is controlled to emit a corresponding colored light or voice prompt indicating that the working status is normal. Alternatively, the normal working status signal can be used as a prerequisite for the equipment to continue to operate.

[0051] Step S0006: If there is no support under the telescopic beam, an abnormal working status signal will be generated. When an abnormal working status signal is generated, the equipment can be further controlled to stop running, and the sound and light generating device can be controlled to issue a warning signal to prompt the staff to conduct a manual inspection. This can prevent the telescopic beam from falling when it is released without support under it.

[0052] like Figure 2 As shown, in this embodiment of the invention, step S003 may include the following sub-steps:

[0053] Sub-step S301: Determine whether there are obstacles on the extension path of the telescopic beam;

[0054] In sub-step S302, if there are no obstacles on the extension path, the telescopic beam is controlled to extend to the preset length value. During this process, the telescopic beam will not collide with the human body or other foreign objects.

[0055] In sub-step S303, if there is an obstacle on the extension path, the distance between the telescopic beam and the obstacle is obtained.

[0056] In sub-step S304, when the distance between the telescopic beam and the obstacle is greater than a threshold, the telescopic beam is controlled to reduce its extension speed, thereby avoiding sudden stops when it is near the obstacle, and thus reducing the impact force when the telescopic beam stops extending.

[0057] In sub-step S305, when the distance between the telescopic beam and the obstacle is less than or equal to a threshold and greater than zero, the telescopic beam is controlled to decelerate at a preset deceleration until it stops extending. By controlling the telescopic beam to decelerate at a certain deceleration, the operation is more stable than the telescopic beam stopping abruptly, and the impact force is reduced.

[0058] In sub-step S306, when the telescopic beam touches the obstacle, the telescopic beam is controlled to immediately stop extending or retracting. In sub-step S306, if an object or person capable of effective movement suddenly appears in the telescopic beam's extension trajectory and collides with it during the beam's extension process, the telescopic beam can be controlled to stop immediately upon initial contact, thereby avoiding scratches and impact accidents.

[0059] like Figure 1 and Figure 2 As shown, the following sub-steps can be added to steps S001 and S003:

[0060] If the distance between the telescopic beam and the obstacle remains constant within a preset time, and the telescopic beam continuously extends or retracts within the preset time, a distance sensor fault signal is generated, and the telescopic beam is controlled to stop extending or retracting. This can be understood as follows: when the telescopic beam's drive (actuator) is in an extension or retraction drive state, if the acquired distance between the telescopic beam and the obstacle does not change accordingly, it is highly likely that the distance sensor is faulty. Therefore, a distance sensor fault signal is generated at this time, and the telescopic beam can be controlled to stop extending or retracting. The next step can also be to control an audio-visual generator based on the distance sensor fault signal to remind personnel to check the equipment.

[0061] Based on sub-step S005, the following step can be added: when there is a support under the telescopic beam, determine whether the telescopic beam is supported by the support; if the telescopic beam is supported by the support, then the telescopic beam is prohibited from telescopically extending or retracting.

[0062] The determination of whether the telescopic beam is supported by the support can be based on the distance between the telescopic beam and the top surface of the support, or on the pressure between the telescopic beam and the top surface of the support. In other words, when the telescopic beam is in contact with the top surface of the support (zero distance), it can be defined as the telescopic beam being supported by the support; when there is a certain pressure between the telescopic beam and the top surface of the support, it can also be defined as the telescopic beam being supported by the support; conversely, if the telescopic beam is not in contact with the top surface of the support or there is no pressure, it can be defined as the telescopic beam not being supported by the support.

[0063] In addition, based on sub-step S005, the following steps can be added: when there is a support under the telescopic beam, detect the overlap dimension of the telescopic beam and the support on the projection plane in the plumb direction; if the overlap dimension is less than the preset support surface dimension, control the telescopic beam to continue to extend; if the overlap dimension is greater than or equal to the preset support surface dimension, control the telescopic beam to stop extending.

[0064] Based on the above steps, the extension of the telescopic beam can only be stopped when the overlapping dimension of the telescopic beam and the support on the vertical projection plane is large enough, that is, when the support can provide a sufficiently large support area for the telescopic beam; otherwise, the telescopic beam is controlled to continue to extend in order to increase the relative area between the telescopic beam and the support in the vertical direction, thereby ensuring that the telescopic beam is stably supported when it is released.

[0065] like Figure 3 As shown, the telescopic beam length control device provided in this embodiment of the invention can be used to implement the control method described in the above embodiments, and therefore has the corresponding technical effects. The telescopic beam length control device includes:

[0066] The telescopic beam detection device 100 is used to detect the actual position and length of the telescopic beam. The device 100 can be an encoder installed on the motor that drives the telescopic beam to change position, and the position of the telescopic beam can be calculated by integrating the encoder data. Alternatively, externally installed photoelectric, ultrasonic, or other position sensors can be used to detect the position of the telescopic beam.

[0067] The support detection device 200 is used to detect whether there is a support under the telescopic beam. The support detection device 200 can use a distance sensor to detect whether there is a support under the telescopic beam. When there is no support, its distance test value will be greater than a preset limit value. It can also detect the pressure on the bottom surface of the telescopic beam. When a support is supporting the telescopic beam, there is pressure, which can be used as a basis for determining whether there is a support.

[0068] The controller 300, the telescopic beam detection device 100 and the support detection device 200 are respectively connected to the controller 300. The controller 300 is used to control the telescopic beam to extend and retract according to the preset length value, and to determine the working status according to whether there is a support under the telescopic beam.

[0069] In this embodiment of the invention, the telescopic beam length control device further includes: an obstacle detection device 400 connected to the controller 300;

[0070] The obstacle detection device 400 includes at least one of a contact switch, a ranging sensor, and a camera, and is mounted on the movable end of the telescopic beam. Additionally, a microswitch can be installed at the end of the telescopic beam as part of the obstacle detection device 400. When a moving object or person suddenly appears in the telescopic beam's extension path, it can be promptly identified and the telescopic beam can be stopped, thereby preventing scratches and collisions.

[0071] Furthermore, the support detection device 200 includes at least one of a photoelectric sensor, an ultrasonic sensor, and an electromagnetic sensor.

[0072] In an optional embodiment, the support detection device 200 is installed at the bottom of the movable end of the telescopic beam, or the support detection device 200 is installed on the support portion of the shaft sidewall. Preferably, the support detection device 200 can be installed on both the support portion of the shaft sidewall and the bottom of the movable end of the telescopic beam, thereby enabling bidirectional corresponding detection. Even if one fails, the other can still provide stable detection information to ensure normal operation of the equipment.

[0073] It should be noted that when the two ends of the telescopic beam are configured as movable ends and can extend and retract to both sides, a telescopic beam detection device 100, a support detection device 200, and an obstacle detection device 400 can be installed at both movable ends of the telescopic beam. The telescopic control method at both ends can still refer to the telescopic beam length control method for duplex elevators described in the above embodiment, and the telescopic movement at both ends can operate independently. If the same power source is used to drive bidirectional telescopic movement, synchronous extension can only be controlled when both ends meet the extension condition, and synchronous retraction can only be controlled when both ends meet the retraction condition.
