Description

Technical Field

[0001] The invention belongs to the field of logistics systems, and in particular relates to a rail breaking gate mechanism and a fire protection system thereof. Background Art

[0002] The hospital rail logistics delivery system uses intelligent rail trolleys to transport medicines, samples, instruments, documents and other items to the required wards, operating rooms and departments through rails, changing the traditional way of manually loading items with trolleys and taking elevators to the required floors before pushing the trolleys to various departments for distribution. The tracks and the trolleys traveling on the tracks must pass through doors or windows on the walls. At present, there are two types of rail logistics rail break fire prevention mechanisms: one is that the power unit controls the rail flip device to disengage to avoid the closing action of fire doors and fire windows. The other is that the power unit controls the translation device for blocking. When users use the above two structures, due to the large amplitude of the rail breaking action, the vehicle may slide out along the break after the rail breaks, and the trolley or cargo may fall and be damaged or even injure pedestrians, posing a serious safety hazard; in order to prevent the above accidents, the existing technology also needs to add additional measures to fix the vehicle on the track, such as chain fixation, which is actually troublesome to use.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of the embodiments of the present invention based on its overall structure.

[0025] Reference Figures 1 to 4 The present invention discloses a rail breaking gate mechanism, comprising: a mounting seat 21, a lever 22, a transmission mechanism, a release mechanism and a partition 23. After the lever 22 moves, the release mechanism is triggered by the transmission mechanism to open, and the components connected to the release mechanism are released. Figure 2 As shown, the mounting seat 21 is a bearing body, and the mounting seat 21 is a planar structure. A groove is provided in the middle of the mounting seat 21 for clamping and installing other components. The raised positions on both sides of the groove are convenient for setting pins, pin shafts and other structures, which is convenient for installation. The lever 22 is located outside the mounting seat 21, and the lever 22 can be an integrated L-shape or assembled from two straight rods; accordingly, a bearing seat is provided on the mounting seat 21 to facilitate fixing the rod.

[0026] The transmission mechanism includes a first connecting rod 31, a lever 34, a first column 51 and a first spring 41. One end of the first connecting rod 31 is hinged to the lever 22, and the other end is hinged to the lever 34. The other end of the lever 34 is suspended. The first column 51 is fixed to the mounting seat 21. The upper end of the first column 51 is hinged to the lever 34 and limits the swing direction of the lever 34. The first spring 41 gives the lever 34 a tendency to move away from the release mechanism. Figures 2 to 4 As shown, the position where the first connecting rod 31 connects to the lever 34 is a U-shaped structure, and the first connecting rod 31 clamps one end of the lever 34. The lever 34 is arc-shaped. Depending on the different hinges between the lever 34 and the first column 51, the lever 34 can be optionally a lever that saves effort (the suspension end of the lever 34 is closer to the hinge) or a lever that transmits large-scale movement (the suspension end of the lever 34 is farther from the hinge). It can be seen in the figure that there is a gap in the middle of the first column 51, and the lever 34 passes through the middle position of the first column 51. One end of the lever 22 is set on the moving path of the window or door.

[0027] In one embodiment, the first spring 41 is a tension spring and is disposed between the first connecting rod 31 and the mounting seat 21. When the lever 22 moves, it overcomes the elastic force of the first spring 41 to raise and lower the end of the lever 34. In another embodiment, a torsion spring can be directly disposed at the hinge between the lever 34 and the first column 51, which can also play the role of applying pre-pressure.

[0028] The release mechanism includes a second column 52, a second link 32, a third link 33, a second spring 42 and a third spring 43. The third link 33 is provided with a clip for clamping the partition 23. The second spring 42 and the third spring 43 push the second link 32 and the third link 33 respectively, so that the second link 32 and the third link 33 enter an interlocking state; that is, the second link 32 has a tendency to approach the third link 33, and the third link 33 has a tendency to move away from the second link 32. When the suspended end of the lever 34 presses the second link 32, the second link 32 avoids the moving path of the third link 33, destroying the interlocking state between the second link 32 and the third link 33, so that the clip of the third link 33 moves and the partition 23 rises and falls.

[0029] As an improvement of the above scheme, the third connecting rod 33 is a U-shaped rod, the U-shaped opening of the third connecting rod 33 serves as a clip, the upper side arm of the third connecting rod 33 is hinged to the upper side of the second column 52, the third spring 43 gives the third connecting rod 33 a tendency to tilt upward, the end of the second connecting rod 32 is hinged to the lower side of the second column 52, the outer side of the second connecting rod 32 is provided with a stepped shaft shoulder, the second spring 42 gives the second connecting rod 32 a tendency to tilt upward, and the second connecting rod 3 2 can temporarily block the lower end of the third link 33 to prevent the left side of the third link 33 from tilting up. The suspended end of the lever 34 is located on the upper side of the second link 32. When the suspended end of the lever 34 moves downward, it presses the second link 32, and the stepped shoulder of the second link 32 is separated from the lower end of the second link 32. After the third link 33 is released, it tilts up and the U-shaped opening faces downward, and the partition 23 is separated from the U-shaped opening (the original state is that the upper side of the partition 23 is stuck in the U-shaped opening by gravity).

[0030] like Figure 3, which is a schematic diagram in the interlocking state. When the window (or door) is closed, the lower end of the lever 22 moves to the right, driving the right end of the first link 31 to tilt up. The lever 34 is used to transmit the power, and the right end (suspended end) of the lever 34 drops. At the same time, the second link 32 is pressed down and no longer hinders the third link 33. Then, the third link 33 moves freely under the drive of the third spring 43, and the U-shaped structure of the third link 33 naturally releases the component to let it fall. When the window (or door) is reopened, the lower end of the lever 22 moves to the left, and at this time, the right end of the first link 31 moves down, and the suspended end of the lever 34 tilts up and detaches from the third link 33; when the window (or door) is completely removed, due to the action of the first spring 41, the first link 31 will drive the lever 34 to reset, and the suspended end of the lever 34 will be reconnected to the upper side of the second link 32.

[0031] As an improvement of the above solution, a roller is provided at the suspension end of the lever 34 to reduce the friction resistance between the suspension end of the lever 34 and the second connecting rod 32, so as to make the movement smoother.

[0032] As an improvement to the above solution, in the interlocked state, the direction of the force applied by the third link 33 to the second link 32 is along the length direction of the second link 32. If the interlocked state of the second link 32 is horizontal, the force applied by the third link 33 is a horizontal force; in this case, no matter how large the force of the third link 33 is, it will not interfere with the second spring 42 (mainly the force at the hinge between the second link 32 and the second column 52). In actual production, there are processing errors, and the force of the third link 33 can be slightly offset relative to the horizontal direction. Figure 4 As shown, the lower end of the third connecting rod 33 is arranged to be flat, so as to fit the stepped shoulder of the second connecting rod 32 which is also flat.

[0033] As an improvement of the above scheme, the release mechanism also includes a third column 53, and the third column 53 is arranged on the mounting seat 21. The upper end of the third column 53 flexibly clamps the second connecting rod 32 and guides the second connecting rod 32 to rise and fall, and the upper end of the third column 53 is also a U-shaped opening. The second spring 42 is a compression spring, and the second spring 42 is sleeved on the third column 53. In one embodiment, the third column 53 can be raised and lowered relative to the mounting seat 21, and the second spring 42 supports the third column 53. When the second connecting rod 32 moves downward, the third column 53 descends. In another embodiment, the third column 53 remains stationary, and the third spring 43 directly supports the second connecting rod 32. Since the second connecting rod 32 swings around the hinge with the second column 52, the connection between the second connecting rod 32 and the third column 53 needs to be appropriately misaligned, such as Figure 4 As shown, the upper end of the third column 53 has an oblong notch.

[0034] As an improvement of the above solution, the release mechanism further includes a fourth column 54, one end of which is hinged to the second column 52, and the other end of which passes through the middle position of the second connecting rod 32. The third spring 43 is a compression spring, and the third spring 43 is sleeved on the fourth column 54. In other solutions, the third spring 43 is a torsion spring directly set at the hinge between the third connecting rod 33 and the second column 52. In a natural state, the third connecting rod 33 will deflect clockwise.

[0035] To achieve the above-mentioned purpose, the present invention further provides a fire protection system using the above-mentioned rail-breaking gate mechanism, comprising a wall 11, a track 13, a baffle 12 and a fire monitoring system, wherein the fire monitoring system is used to control the switch of the baffle 12, the baffle 12 is hinged to the wall 11 to cover the gap in the wall 11, the track 13 is installed above the gap in the wall 11, the lower side of the track 13 is groove-shaped, and the upper side is flat, and a gap is provided in the middle of the track 13 to accommodate a partition 23 (the gap is conveniently extended along the width of the track 13), and the partition 23 temporarily blocks and seals the middle groove of the track 13 after it falls, and the lever 22 is in the movable path of the baffle 12. Figure 2 and 3 As shown, the width direction of the track 13 is further reinforced by the L-shaped corner bracket and the wall 11, and a protective cover is arranged around the partition 23. In order to accelerate the descent of the partition 23, the partition 23 also applies a downward thrust through the fourth spring 44.

[0036] In the initial state, the lever 22 is vertically stationary, and the upper end of the partition 23 is clamped by the U-shaped opening of the third connecting rod 33; in the triggered state, the lever 22 is hit by the baffle 12, the third connecting rod 33 is released and the opening moves downward, and the partition 23 is lowered; when the baffle 12 is reopened, the lever 22 drives the suspended end of the lever 34 to tilt upward without pressing the second connecting rod 32. The baffle 12 mentioned here can be a window, a door, or other components. When the baffle 12 is reopened, the partition 23 is still in the state of blocking the track 13. At this time, after the partition 23 is pushed upward by the tool, the upper side of the partition 23 first enters the U-shaped opening of the third connecting rod 33, and then pushes the third connecting rod 33 open. The third connecting rod 33 swings counterclockwise and presses the second connecting rod 32 downward again, and finally gets stuck on the stepped shoulder of the second connecting rod 32 to enter the interlocking state. At this time, the lower side of the third connecting rod 33 naturally supports the upper side of the partition 23, and the partition 23 will not fall after the operator removes the external force. It should be noted that the upper and lower lengths of the U-shaped opening of the third connecting rod 33 should be reasonably adjusted to ensure that the upper side of the partition 23 can enter and exit.

[0037] As an improvement of the above scheme, the fire monitoring system includes a sensor, a door closer, a single chip microcomputer and a power supply, and the single chip microcomputer is connected to the sensor, the door closer and the power supply. The sensor and the system for monitoring the fire belong to the prior art and can be directly referred to the construction specification, which will not be described here.

[0038] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the present invention and various different selections and changes. The scope of the present invention is intended to be limited by the claims and their equivalents.
