Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automatic track flipping, in particular to a novel automatic track flipping device. Background Art
[0002] The rail trolley logistics system is usually used in hospitals, libraries or other places where items need to be transported frequently. The system is mainly composed of advanced computers with corresponding control software, electric automatic walking trolleys, and the use of CAN communication technology, photoelectric positioning technology and mechanical transmission technology to implement on-track transportation of items. Small rails are used to connect the transportation points. Since the connecting rails pass through various buildings, in order to prevent the connection between various fire partitions from being cut off when a fire occurs, fire blocking is necessary. Therefore, it is very necessary to develop the automatic rail flipping device to cooperate with the corresponding fire blocking equipment for fire blocking.
[0003] The existing track automatic flipping device has the following defects:
[0004] At present, the turning method of the rail trolley logistics system adopts the turning method of mechanical rack and gear positioning, which has the following main disadvantages: (1) It is difficult to control the clearance between the mechanical rack and gear. Since the transmission track is very long, thermal expansion and contraction will occur during normal use. The thermal expansion and contraction of the connecting tracks on both sides will increase or reduce the distance between the turning track and the fixed side track on the turning device, causing the mechanical rack and gear of the turning device to swell or disengage. Because the rail logistics system is a system used 24 hours a day, changes in the operating environment temperature are inevitable. When the operating environment temperature of the track gradually rises, the track stretches, causing the gear and rack to swell, making the turning device unable to turn and affecting the action of the fire blocking equipment. When the operating environment temperature of the track gradually drops, the track shrinks. The gear and rack are decoupled or semi-decoupled. At this time, the track cannot maintain a flat connection, which will cause the moving trolley to fall or get stuck; (2) The turning section of the track of the track turner cannot be accurately positioned up and down or left and right because it is not docked with the fixed tracks on both sides, causing the track to be unable to align and produce a vertical height difference. The track height difference will damage the track trolley's running structure. When the track cannot be aligned left and right, the trolley will get stuck when traveling, damaging the trolley structure, increasing the daily maintenance workload of the track trolley, and bringing a lot of maintenance costs to users; (3) When the mechanical rack of the track turner is too tight, the push-pull electromagnet stroke cannot disengage the mechanical rack from the gear, causing the turning section of the track to be unable to move, making it impossible for the fire blocking equipment to be effectively blocked. For this reason, a solution is needed. Utility Model Content

[0011] Preferably, a track turning-in-place trigger switch is provided at one end of the shaft-end fixed track close to the turning section track.
[0012] Preferably, a track reset trigger switch is provided at one end of the locking section track close to the flip section track.
[0013] (III) Beneficial effects
[0014] The utility model provides a new type of track automatic flipping device, which has the following beneficial effects:
[0015] (1) The utility model adopts double-sided guide rails and a fixed slide slot telescopic mechanism. The guide rails and the slide slots are accurately fixed. The high rigidity of the guide rails effectively ensures that the connection between the flipping section and the connecting rails on both sides is smooth and accurate without left and right shaking, thereby ensuring that the electric trolley travels quickly and smoothly, reducing the structural damage caused by the step difference at the track connection when the electric trolley passes through the existing track turner, reducing maintenance costs and improving transportation efficiency.
[0016] (2) The utility model adopts an electric push rod to drive the guide rail to slide to separate the connection between the track turning section and the track. The simple guide rail stroke control improves the track turning efficiency, thereby ensuring the action of the fire blocking equipment and avoiding the expansion of fire losses caused by the failure of the track to turn over.
[0017] (3) The utility model adopts a double-sided guide rail structure in which the turning section track and the two side tracks penetrate each other, which can easily adjust the distance between the turning section and the two side tracks. The expansion and contraction of the track caused by thermal expansion and contraction of the track will not cause the track to shake in the horizontal direction and left and right directions. The travel of the guide rail ensures that the track can be aligned up and down and left and right when it is stretched, avoiding the temperature change of the track use environment. The turning section will not produce a step difference up and down and left and right, which affects the travel of the track trolley. The installation and debugging are convenient and simple, saving construction, installation and debugging time. BRIEF DESCRIPTION OF THE DRAWINGS
