Description

Technical Field

[0001] The utility model relates to a docking device, in particular to a vertical docking device for a rail trolley suitable for vertical lifting of a medical logistics trolley. Background Art

[0002] The existing medical logistics rail trolley is also called a rail-type logistics transmission system (hereinafter referred to as the system). Under the control of a computer, the cargo trolley is controlled to transport items on a dedicated track, and the various departments of the hospital are connected through a sending and receiving workstation and a transportation track. The computer-controlled track changer controls the cargo trolley to switch to different tracks, thereby realizing a system in which the cargo trolley can transfer items between various departments.

[0003] At present, the medical logistics rail trolley system basically adopts a track of about 20 cm, and the motor carried by the trolley itself provides the carrying power throughout the whole process. It can carry 50 kg in the horizontal direction along the set horizontal track. In the vertical shaft, a rack is installed on the track, and the trolley motor is used to drive the climbing. Due to the limitation of the climbing ability of the trolley motor, the system's trolley can only carry about 15 kg in the vertical direction, and it cannot provide higher performance, which seriously drags down the entire system. The carrying capacity cannot meet the current hospital requirements. Specifically, due to the influence of the track width and the volume of the trolley, as well as the limited volume of the trolley motor, the motor driving capacity is close to the upper limit, and the purpose of increasing the trolley's carrying capacity cannot be achieved directly by increasing the motor driving force.

[0004] If the purpose is to increase the carrying capacity of the entire system, the size of the track can be changed, the structure of the trolley can be modified, and a larger motor can be used to increase the carrying capacity of the system. However, this will also increase the size and weight of the trolley, and the cost of the track and trolley will also increase. At the same time, the hospital will need to provide a larger space to install the rail trolley logistics system. Therefore, this method is not suitable for improving the vertical carrying capacity of the trolley in the existing technology. It is urgent to design a device that solves the vertical carrying capacity of the rail trolley without increasing the cost and system structure too much. Utility Model Content

[0005] The purpose of the utility model is to provide a rail trolley vertical docking device which improves the carrying capacity in a vertical shaft by transferring a logistics trolley to a lifting structure and using the lifting structure to carry the logistics trolley, thereby breaking through the overall carrying capacity of the system.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a vertical docking device for a rail trolley, the innovation of which is that it includes a lifting motor, a lifting car, a switch and a pulling assembly, and a vertical track arranged in the hoistway.

[0007] The shaft has a plurality of shaft openings arranged in layers along its height direction, and each shaft opening corresponds to and is adjacent to an external horizontal track arranged in layers, and the horizontal track is used to carry the horizontal sliding of the medical logistics trolley.

[0008] The lifting car is slidably matched with the vertical track in the hoistway, and the lifting motor is installed on the lifting car to drive the lifting car to slide up and down along the vertical track.

[0009] The interior of the lifting car is provided with a pulling assembly, and the pulling assembly includes a linear module and a traction motor, and the track switch is installed on a slider of the linear module.

[0010] When the medical logistics trolley on any horizontal track needs to climb or descend, the lifting car slides along the vertical track under the drive of the lifting motor and stops at the docking position with the medical logistics trolley. The traction motor drives the linear module to make the diverter move linearly through the slider and fit with the corresponding horizontal track. The medical logistics trolley enters the lifting car along the diverter. The diverter is then separated from the horizontal track under the action of the pulling assembly, and the lifting car carries the medical logistics trolley to the target position.

[0011] In the above technical solution, the diverter includes a diverter seat, a conversion rail, a transition rail and a track change drive unit. A transition rail is provided on one side of the diverter seat, and two transition rails are provided on the other side. Both ends of the conversion rail are slidably matched with the diverter seat, and the conversion rail is driven by the track change drive unit to slide along the diverter seat, so that the conversion rail is docked with a different transition rail on the other side of the diverter seat.

[0012] In the above technical solution, the track change drive unit includes a motor, a transmission gear and a transmission rack. The motor is installed at the bottom of the conversion rail, and the transmission gear is arranged on the power output shaft of the motor. The transmission rack is fixed on the conversion rail seat, and the transmission gear is meshed with the transmission rack.

[0013] In the above technical solution, conversion sliders are provided at the bottoms of both ends of the conversion rail, and the conversion sliders are slidably matched with the slide grooves of the conversion rail seat.

[0014] In the above technical solution, a plurality of guide blocks are provided at the end of the diverter, and each guide block is used to be inserted into a slot at the end of the corresponding horizontal rail, so that the diverter can be accurately positioned and docked with the corresponding horizontal rail.

[0015] In the above technical solution, a fire door with a double-opening structure is provided at each well opening of the well.

[0016] The positive effect of the utility model is that after adopting the vertical direction docking device of the rail trolley of the utility model, since the utility model includes a lifting motor, a lifting car, a rail switch and a pulling assembly, and a vertical track arranged in the hoistway,

[0017] The shaft has a plurality of shaft openings arranged in layers along its height direction, and each shaft opening corresponds to and is adjacent to an external horizontal track arranged in layers, and the horizontal track is used to carry the horizontal sliding of the medical logistics trolley.

[0018] The lifting car is slidably matched with the vertical track in the hoistway, and the lifting motor is installed on the lifting car to drive the lifting car to slide up and down along the vertical track.

[0019] The interior of the lifting car is provided with a pulling assembly, and the pulling assembly includes a linear module and a traction motor, and the track switch is installed on a slider of the linear module.

[0020] Specifically, each floor of the hospital is provided with a horizontal track, and the horizontal track of each floor is connected to the well opening set on the corresponding floor of the well. When the medical logistics trolley on the horizontal track of any floor needs to climb or descend, the lifting car slides along the vertical track under the drive of the lifting motor and stops at the docking position with the medical logistics trolley. The traction motor drives the linear module to make the diverter move linearly through the slider and fit with the corresponding horizontal track. The medical logistics trolley enters the lifting car along the diverter. The diverter is then separated from the horizontal track under the action of the pulling component, and the lifting car brings the medical logistics trolley to the target position (floor).

[0021] The utility model sets a lifting structure in the shaft, and the track switch in the lifting car can be docked with the external horizontal track. In this way, the medical logistics trolley is only responsible for traveling horizontally along the horizontal track, and the lifting structure carries the trolley up and down in the vertical direction, replacing the technical solution in the prior art that the trolley itself directly runs up and down along the track, greatly improving the vertical carrying capacity of the rail trolley, eliminating the bottleneck of the rail trolley transportation, and making the carrying capacity of the entire rail trolley system exceed 50 kilograms. At the same time, it solves the transportation requirements of hospital items, reduces the labor transportation cost, and improves work efficiency. At the same time, it avoids overloading of the trolley, greatly improves the service life of the trolley, and saves the high maintenance cost of the logistics system.

[0027] like Figure 1 , 2 , 3, and 4, a vertical docking device for a rail trolley includes a lifting motor 2, a lifting car 3, a track switch 4, a pulling assembly 5, and a vertical track 1 arranged in a hoistway.

[0028] The shaft has a plurality of shaft openings arranged in layers along its height direction, and each shaft opening corresponds to and is adjacent to an external horizontal track arranged in layers, and the horizontal track is used to carry the horizontal sliding of the medical logistics trolley.

[0029] The lifting car 3 is slidably matched with the vertical track 1 in the hoistway, and the lifting motor 2 is installed on the lifting car 3 to drive the lifting car 3 to slide up and down along the vertical track 1.

[0030] The interior of the lifting car 3 is provided with a pulling assembly 5, and the pulling assembly 5 includes a linear module 51 and a traction motor 52. The diverter 4 is installed on a slider of the linear module 51.

[0031] When the medical logistics trolley on any horizontal track needs to climb or descend, the lifting car 3 slides along the vertical track 1 under the drive of the lifting motor 2 and stops at the docking position with the medical logistics trolley. The traction motor 52 drives the linear module 51 to make the diverter 4 move linearly through the slider and fit with the corresponding horizontal track. The medical logistics trolley enters the lifting car 3 along the diverter 4. The diverter 4 is then separated from the horizontal track under the action of the pulling assembly 5, and the lifting car 3 carries the medical logistics trolley to the target position.

[0032] like Figure 4 As shown, in order to adapt to docking with horizontal rails at different positions and meet the scheduling requirements within the system, the diverter 4 includes a diverter seat 41, a conversion rail 42, a transition rail 43 and a track change drive unit 44. A transition rail 43 is provided on one side of the diverter seat 41, and two transition rails 43 are provided on the other side. Both ends of the conversion rail 42 are slidably matched with the diverter seat 41, and the conversion rail 42 is driven by the track change drive unit 44 to slide along the diverter seat 41, so that the conversion rail 42 docks with a different transition rail 43 on the other side of the diverter seat 41.

[0033] like Figure 4 As shown, in order to enable the conversion rail to be accurately docked with the different transition rails on one side of the conversion rail seat, the track change drive unit 44 includes a motor 441, a transmission gear 442 and a transmission rack 443. The motor 441 is installed at the bottom of the conversion rail 42, and the transmission gear 442 is arranged on the power output shaft of the motor 441. The transmission rack 443 is fixed on the conversion rail seat 41, and the transmission gear 442 is meshed with the transmission rack 443.

[0034] like Figure 4 As shown, in order to ensure smooth sliding of the conversion rail and prevent jamming, conversion sliders 421 are provided at the bottom of both ends of the conversion rail 42, and the conversion sliders 421 are slidably matched with the slide grooves of the conversion rail seat 41.

[0035] like Figure 2 As shown, in order to achieve accurate docking of the diverter with the external horizontal track, a plurality of guide blocks 6 are provided at the end of the diverter 4, and each guide block 6 is used to be inserted into a slot at the end of the corresponding horizontal track, so that the diverter 4 can be accurately positioned and docked with the corresponding horizontal track.

[0036] like Figure 2 As shown, in order to prevent misoperation and protect the rail trolley, each well opening of the well is provided with a fire door 7 of a split structure. Only when the trolley drives to the corresponding well opening, a corresponding notification will be sent to the system to show that there is a task of the trolley entering the lifting car. After the system receives the trolley request, when the lifting car stops at the docking position with the trolley, the fire door of this floor will be opened to facilitate the docking of the switch with the external horizontal track under the action of the pulling assembly.

[0037] The working process of this utility model: Figure 1 As shown in the figure, each floor of the hospital is equipped with a horizontal track, and the horizontal track of each floor is connected to the well opening set on the corresponding floor of the well. When the medical logistics trolley on the horizontal track of any floor needs to climb or descend to a different floor,

[0038] The medical logistics trolley 8 drives to the corresponding shaft entrance in advance and notifies the system that there is a trolley entering the lifting car 3 task. The system receives the trolley's request to join the lifting car task. The lifting car 3 slides along the vertical track 1 driven by the lifting motor 2 and stops at the docking position with the medical logistics trolley. Only then will the fire door 7 on this floor be opened.

[0039] The traction motor 52 drives the linear module 51 to make the diverter 4 move linearly through the slider and fit with the corresponding horizontal track 9, eliminating the distance between the horizontal track 9 and the transition rail 43 of the diverter 4, and inserting the guide block 6 set at the end of the diverter 4 into the slot at the end of the horizontal track 9, so that the diverter 4 can be accurately positioned and docked with the external horizontal track 9 after translation.

[0040] The medical logistics trolley 8 enters the lifting car 3 along the diverter 4, and the diverter 4 is separated from the horizontal track under the action of the pulling component 5, and the fire door 7 of this floor is closed again. The lifting car 3 carries the medical logistics trolley to the target position (floor) under the action of the lifting motor 2.

[0041] When the elevator car 3 reaches the target floor, the system will be notified again that a trolley has exited the elevator car task. The exit steps are opposite to the entry steps, so no further details will be given.

[0042] The utility model sets a lifting structure in the shaft, and the track switch in the lifting car can be docked with the external horizontal track. In this way, the medical logistics trolley is only responsible for traveling horizontally along the horizontal track, and the lifting structure carries the trolley up and down in the vertical direction, replacing the technical solution in the prior art that the trolley itself directly runs up and down along the track, greatly improving the vertical carrying capacity of the rail trolley, eliminating the bottleneck of the rail trolley transportation, and making the carrying capacity of the entire rail trolley system exceed 50 kilograms. At the same time, it solves the transportation requirements of hospital items, reduces the labor transportation cost, and improves work efficiency. At the same time, it avoids overloading of the trolley, greatly improves the service life of the trolley, and saves the high maintenance cost of the logistics system.

[0043] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
