Description

Technical Field

[0001] The utility model relates to the technical field of logistics transmission equipment, in particular to a hospital logistics transmission system. Background Art

[0002] Various daily medical supplies in hospitals need to be delivered quickly. Traditional manual delivery of medical supplies is time-consuming and laborious. Automated logistics transmission systems are increasingly used in hospitals. Hospital logistics transmission systems include horizontal transmission between the same floors and vertical transmission between different floors.

[0003] During the vertical transmission process, a transmission elevator shaft needs to be set up between floors. A frame and tracks are set up in the elevator shaft. The logistics boxes containing medical supplies are transferred to the car and moved up and down along the track driven by the elevator.

[0004] For example, Chinese utility model patent publication number CN 210635585 U discloses a vertical lifting device for placing multiple transmission boxes, in which a motor drives a car and a counterweight block to move up and down through a drive chain and a steel wire rope. Chinese utility model patent publication number CN207404407U discloses a logistics system for hospitals, in which a lifting device includes a motor, a drive chain, and a drive shaft arranged at the top of the elevator shaft, and a driven sprocket arranged at the bottom of the elevator shaft, and the car is driven to move up and down through a drive chain.

[0005] Both solutions require that some parts of the lifting device, such as the counterweight and drive chain, be placed on the side of the car. Since most hospitals are built without a reserved elevator shaft for the hospital logistics system, the floor needs to be modified, and the hospital floor space is very valuable. The existing vertical lifting device of the hospital logistics system cannot further reduce the occupied area. Utility Model Content

[0006] The problem to be solved by the utility model is to provide a hospital logistics transmission system and a vertical transmission device thereof which can save the occupied area as much as possible.

[0007] In order to solve the above-mentioned technical problems, the utility model provides a vertical transmission device of a hospital logistics transmission system, which is used to transport logistics boxes up and down between different floors, and includes a car for placing logistics boxes and capable of moving up and down in a shaft; a lifting device connected to the car to provide power for the up and down movement of the car; a track installed in the shaft to provide a channel for the up and down movement of the car; the lifting device includes a cable for connecting the car and the lifting device, a winding roller for winding the cable, a winding roller driving device for driving the winding roller to rotate, and a rope arrangement mechanism.

[0008] By adopting the above technical solution, the motor, wire rope, winding roller and other lifting equipment can be set on the top of the car. There is no need to set a counterweight on the side of the car in the hoistway, and there is no need to leave space for the counterweight, which can save the hospital's usable area.

[0009] As a further improvement, the rope arrangement mechanism includes a frame and a reciprocating mechanism installed on the frame, the reciprocating mechanism is connected to a moving seat, the reciprocating mechanism drives the moving seat to reciprocate in a direction parallel to the winding roller, and a rope guiding device is installed on the moving seat.

[0010] Since the vertical transmission device of the hospital logistics transmission system is not used for personnel riding, but only for the transmission of medical supplies, the transmission speed is much faster than other vertical transmission devices such as passenger and freight elevators. The rope is retracted and released very quickly, resulting in a large swing amplitude of the rope, which easily causes chaos in the reeling of the rope.

[0011] In order to solve the above problems, the utility model has made further improvements. The rope guiding device includes a guide wheel installed on a movable seat. The axial direction of the guide wheel is perpendicular to the axial direction of the winding roller. The guide wheel is arranged in front of the rope guiding device. At least three guide wheels are arranged.

[0012] By adopting the above technical solution, a guide wheel is provided which is perpendicular to the axial direction of the winding roller. The position of the rope can be constrained by the guide wheel before the rope enters the rope outlet wheel, so that the rope will not swing violently when running at high speed.

[0013] As a further improvement, the guide wheels are located on both sides of the cable and are arranged in a staggered manner.

[0014] As a further improvement, a guide groove is provided on the guide wheel.

[0015] As a further improvement, the movable seat comprises a mounting plate, a rotating shaft is mounted on the mounting plate, and a guide wheel is mounted on the rotating shaft.

[0016] Since the vibration generated by the high-speed running cable easily affects the stability of the moving seat, in order to solve this problem, the utility model has made further improvements. At least one guide hole is set at each end of the moving seat, and at least two guide columns are installed on the frame, and the guide columns pass through the guide holes. Both ends of the moving seat are restricted by the guide columns, which can make the movement of the moving seat more stable and less vibrating.

[0017] As a further improvement, the cable guiding device comprises a rope output wheel mounted on the movable seat, and the axial direction of the rope output wheel is parallel to the axial direction of the winding roller.

[0018] As a further improvement, the winding roller is provided with a spiral limiting groove. By providing the limiting groove, the winding position of the cable on the winding roller can be well regulated, and the cable will be wound onto the winding roller strictly according to the position of the limiting groove.

[0019] The utility model also relates to a hospital logistics transmission system, comprising a horizontal transmission device and a vertical transmission device, wherein the horizontal transmission device is used to transmit logistics boxes on the same floor, and the vertical transmission device is used to transmit logistics boxes on different floors, and the vertical transmission device is the vertical transmission device of the above-mentioned hospital logistics transmission system.

[0020] After adopting such a structure, the vertical transmission device of the hospital logistics transmission system of the utility model sets the lifting equipment such as the motor, wire rope, winding roller, etc. on the top of the car, and there is no need to set a counterweight block on the side of the car in the hoistway, and there is no need to leave space for the counterweight block, which can save the use area of ​​the hospital. The vertical transmission device of the utility model ensures the stability of the cable winding when all components are running at high speed, and prevents the cable from swinging in a large amplitude and causing chaos in the cable winding.

[0021] In order to solve the above problems, the utility model has made further improvements. The rope guiding device includes a guide wheel installed on a movable seat, the axial direction of the rope output wheel is parallel to the axial direction of the winding roller, the axial direction of the guide wheel is perpendicular to the axial direction of the winding roller, and the guide wheel is arranged in front of the rope guiding device. At least three guide wheels are arranged.

[0022] By adopting the above technical solution, in addition to setting a rope outlet wheel in the same direction as the winding roller, a guide wheel is also set which is perpendicular to the winding roller and the rope outlet wheel. The position of the rope can be constrained by the guide wheel before the rope enters the rope outlet wheel, so that the rope will not swing violently when running at high speed.

[0039] like Figure 1 and Figure 2As shown, the vertical transmission device of the hospital logistics transmission system of the utility model is used to transport logistics boxes up and down between different floors, including a car 1 for placing logistics boxes 2 and capable of moving up and down in a shaft 3; a lifting device connected to the car 1 to provide power for the up and down movement of the car 1; a track installed in the shaft 3 to provide a channel for the up and down movement of the car; the lifting device includes a cable 4 for connecting the car 1 and the lifting device, a winding roller 5 for winding the cable 4, a winding roller driving device driving motor 6 for driving the winding roller 5 to rotate, and a rope arrangement mechanism 7, and the cable 4 is generally a steel wire rope.

[0040] By adopting the above technical solution, the driving motor 6, the cable 4, the winding roller 5 and other lifting equipment can be set on the top of the car. There is no need to set a counterweight on the side of the car in the hoistway 3, and there is no need to reserve space for the counterweight, which can save the hospital's usable area.
