Description

Technical Field

[0001] The utility model belongs to the technical field of sling devices, and specifically relates to an aerial cross turntable. Background Art

[0002] The electric power-assisted lifting device is mainly used in conjunction with the track. For example, Chinese patent CN220513057U discloses an electric power-assisted lifting device. When it is used, the lifting belt is fixed on the track, and the lifting bag is installed through the lifting hole. The user is fixed on the lifting bag, and the caregiver controls the lifting and lowering movements of the user through the control handle to achieve power-assisted operation. In the prior art, the track mainly includes structures such as circular track and straight track. After the electric power-assisted lifting device is connected to the track, it can only move along the direction set by the track, resulting in a strong limitation on the range of movement of the electric power-assisted lifting device; in addition, there is no detection and feedback on the movement of the electric power-assisted lifting device, making it difficult to achieve refined control. Utility Model Content

[0003] The utility model aims to provide an aerial cross turntable to solve the technical problems existing in the prior art.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0025] Example

[0026] like Figures 1 to 7 As shown, this embodiment provides an aerial cross turntable, including a mounting plate, a shell is fixedly provided at the lower part of the mounting plate, a plurality of connecting holes are provided at the upper part of the mounting plate, and the aerial cross turntable is fixedly mounted on other supporting components through the mounting plate.

[0027] The outer shell adopts an arc-shaped outer shell structure, a transition plate is arranged at the bottom of the outer shell, the interior of the outer shell is hollow, a rotating drive mechanism is arranged inside the outer shell, the rotating drive mechanism is connected to the transition plate, the transition plate is driven to rotate by the rotating drive mechanism, the transition plate is connected to a ceiling rail, and the ceiling rail moves with the transition plate.

[0028] In this embodiment, the rotary drive mechanism includes a rotary motor, a first synchronous wheel arranged on the output shaft of the rotary motor, a second synchronous wheel connected to the first synchronous wheel through a synchronous belt, a rotating shaft connected to the second synchronous wheel, and a transition plate connected to the rotating shaft; when the rotary motor is in operation, the rotary motor drives the first synchronous wheel to rotate, the first synchronous wheel drives the second synchronous wheel to rotate through the synchronous belt, the second synchronous wheel drives the rotating shaft to rotate, and thus drives the transition plate to rotate through the rotating shaft.

[0029] The transition plate drives the ceiling rail to rotate. In this embodiment, the aerial cross turntable is used in combination with the cross track. The cross track includes a longitudinal track and a transverse track. A space is reserved in the middle of the longitudinal track and the transverse track. The ceiling rail is located in the reserved space. The ceiling rail is controlled by a rotating drive mechanism to achieve 0° and 90° rotation, so as to control the connection between the ceiling rail and the transverse track or the longitudinal track of the cross track. Among them, the 0° and 90° rotation refers to the rotation angle of the ceiling rail based on the longitudinal or transverse direction. For example, when the ceiling rail is connected to the transverse track of the cross track, the ceiling rail is rotated by 0°, and when the ceiling rail is connected to the longitudinal track of the cross track, the ceiling rail is rotated by 90°.

[0030] The rotation drive mechanism controls the rotation of the overhead rail. On this basis, this embodiment is also provided with a limit and detection mechanism for confirming the rotation status and controlling it. Specifically, the limit and detection mechanism includes a support plate arranged in the housing and connected to the mounting plate, limit blocks symmetrically arranged on both sides of the support plate, and two detection photoelectric devices arranged on the support plate; the support plate has a through hole in the middle, and the rotating shaft passes through the through hole. A stopper that moves with the transition plate is arranged on the transition plate. The stopper is located between the two limit blocks and is used in conjunction with the limit blocks. The positions of the two limit blocks correspond to the positions of the turntable rotating 0° and 90° respectively. When rotating to the corresponding limit block, the limit block abuts against the stopper to achieve the limit. The detection photoelectric includes a 90° detection photoelectric located on one side and used to confirm the position of the turntable, and a 0° detection photoelectric located on the other side and used to confirm the position of the turntable. It should be noted that the 0° detection photoelectric and the 90° detection photoelectric are installed through a bracket, and the structure and working principle of the 0° detection photoelectric and the 90° detection photoelectric are the same. They are named separately here for the convenience of distinction. The position of the aerial cross turntable is confirmed by the 90° detection photoelectric or the 0° detection photoelectric to determine whether the aerial cross turntable has been rotated into place.

[0031] The ceiling rail is used to connect with the transverse track or the longitudinal track of the cross track. In order to facilitate control, a detection switch, an RFID chip and a switch detection induction bracket are arranged on the ceiling rail in this embodiment.

[0032] There are two switch detection induction brackets located at the bottom of the ceiling rail, one of which is located on the right side of the front end of the ceiling rail, and the other is located on the left side of the rear end of the ceiling rail. The function of the switch detection induction bracket is to determine whether the equipment (hanger) has entered the ceiling rail. When the equipment is outside the aerial cross turntable, the equipment moves along the horizontal or longitudinal track of the cross track. When approaching the aerial cross turntable, the detection switch detects the presence of the induction bracket to confirm whether the track on which the equipment is moving is connected to the ceiling rail of the aerial cross turntable, thereby confirming whether the equipment can enter the aerial cross turntable. When the switch detection induction bracket is detected, it means that the track on which the equipment is moving is connected to the ceiling rail of the aerial cross turntable. At this time, the equipment can enter the aerial cross turntable normally.

[0033] After the equipment enters the aerial cross turntable, when the equipment is located inside the aerial cross turntable, the equipment moves on the ceiling rail. When the equipment moves to the detection switch position, the detection switch is triggered (which can be controlled by telescopic pole). At this time, the aerial cross turntable can rotate, control the rotation motor to start, control the ceiling rail to rotate, and change the connection structure between the ceiling rail and the cross track. If the ceiling rail is connected to the horizontal track of the cross track, it is changed to the longitudinal track connection of the ceiling rail and the cross track; if the ceiling rail is connected to the longitudinal track of the cross track, it is changed to the horizontal track connection of the ceiling rail and the cross track.

[0034] The RFID chip is mainly used to determine the location of the device. In this embodiment, the RFID chip is located in the middle of the overhead rail. When the device moves to the location of the RFID chip, the current location of the device is confirmed by sensing the RFID chip.

[0035] The external cross track and the control of the electrical components inside the aerial cross turntable are installed together in an external separate control box, which does not occupy the space inside the turntable, so as to reduce the volume of the turntable.

[0036] The above is the preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements without departing from the design principle and technical solution of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
