Description

Technical Field

[0001] The present invention relates to a locking device, and particularly to a locking device for parallel train carriages. Background Art

[0002] In the existing train transportation system during operation, the train undergoes the processes of deceleration, stopping, passenger boarding and alighting, and acceleration at each stop, which seriously reduces the overall operation efficiency.

[0003] In order to improve the operation efficiency of the train, various methods have been proposed.

[0004] Chinese patent application publications CN118770295A and CN118770304A disclose trains that can run in parallel on two lines and exchange movable carriages. When exchanging the movable carriages, the parallel carriages need to be strictly synchronized, so it is necessary to lock the carriages of the two parallel trains. Summary of the Invention

[0005] The object of the present invention is to provide a carriage locking device for a double - line parallel train.

[0006] The technical solution of the present invention is to construct a locking device for parallel train carriages, which includes an active component and a passive component. The active component and the passive component are respectively arranged on two carriages; the active component includes a pull rod, a mounting seat and a pull rod driving device. A clamping block is arranged at the first end of the pull rod, the second end of the pull rod is rotatably connected to the mounting seat, the clamping block and the pull rod are distributed in a T - shape, the pull rod driving device is connected to and drives the pull rod to rotate, and the rotation plane of the pull rod is a horizontal plane;

[0007] The passive component includes a C - shaped groove, a positioning component and a limiting component. The positioning component is connected to the inside of the C - shaped groove. The notch of the C - shaped groove is horizontally arranged, and the cross - section of the notch is T - shaped, which cooperates with the clamping block and the first end of the pull rod;

[0008] The limiting component includes a sensor and its control circuit. The control circuit is connected to the positioning component and triggers the positioning component to fix the clamping block in the C - shaped groove when the clamping block moves to a predetermined position.

[0009] In one embodiment, the positioning component includes a first positioning module. The first positioning module includes a positioning pin that can be inserted into the C - shaped groove. A return spring is sleeved on the positioning pin, and the return spring is located outside the C - shaped groove. It also includes a traction device, and the traction device is connected to the end of the positioning pin far from the C - shaped groove;

[0010] A positioning hole that cooperates with the positioning pin is arranged on the clamping block;

[0011] The predetermined position of the clamping block is the position where the positioning hole is aligned with the positioning pin.

[0012] The sensor described above is an optoelectronic sensor, which is installed in the C-shaped groove and is triggered when the clamping block reaches a predetermined position.

[0013] The limiting component further includes a lifting stop block and a lifting control module. The lifting control module is connected to the control circuit. The lifting stop block can be inserted into the C-shaped groove. The sensor is a pressure sensor, which is installed on or connected to the lifting stop block. The position of the lifting stop block is: in the state where the lifting stop block is inserted into the C-shaped groove, when the clamping block moves to the predetermined position, the clamping block contacts the lifting stop block and triggers the pressure sensor.

[0014] The traction device described above is an electromagnetic or electric or hydraulic or pneumatic driving device.

[0015] The clamping block is a cylinder, and chamfers or fillets are provided at the edges of the upper and lower bottom surfaces of the cylinder, or chamfers or fillets are provided at the end of the positioning pin inserted into the C-shaped groove, or chamfers or fillets are provided at the end of the positioning hole.

[0018] In one of the embodiments, the positioning component further includes a second positioning module, which has the same structure as the first positioning module and is symmetrically arranged above and below the C-shaped groove with respect to the first positioning module.

[0019] Advantages and beneficial effects of the present invention: The active component and the passive component in the present invention are respectively arranged on the carriages of two trains in the same direction. When train one equipped with the active component catches up with train two equipped with the passive component, train one extends the second end of the pull rod, so that the clamping block slides into the C-shaped groove of train two from the rear end. The positioning component locks the clamping block in the C-shaped groove to complete the connection of the two trains and enables the two trains to run strictly synchronously. After the positioning component cancels the locking with the clamping block, either train one accelerates or train two decelerates, which can make the clamping block slide out from the front end of the C-shaped groove to complete the separation of the two trains. The structure of the present invention is simple, stable and reliable. Description of the Drawings

[0033] Embodiment 1

[0034] As Figure 1 shown, the locking device M of the parallel train carriages of the present invention is disposed on the carriages a and b running in the same direction in parallel. The carriages a and b in the figure are being locked by the locking device M of the parallel train carriages.

[0035] As Figures 2 - 6 ​As shown, the locking device M of the parallel train carriages includes an active component 1 and a passive component 2, and the active component 1 and the passive component 2 are respectively arranged on two carriages a and b.

[0036] The active component 1 includes a pull rod 11, a mounting seat 12 and a pull rod driving device 13.

[0037] The passive component 2 includes a C-shaped groove 21, a positioning component 22 and a limiting component. The positioning component 22 is connected to the inside of the C-shaped groove 21, the notch of the C-shaped groove 21 is horizontally arranged, and the cross section of the notch (see Figure 6 21 in the figure) is T-shaped and is matched with the clamping block 14 and the first end of the pull rod 11, that is, the T shape formed by the first end of the pull rod 11 and the clamping block 14 can be slidably matched with the cross-sectional T shape of the notch.

[0038] As Figure 6 shown, the positioning component includes a first positioning module. The first positioning module includes a positioning pin 221 that can be inserted into and penetrate through the C-shaped groove 21. A return spring 222 is sleeved on the positioning pin 221, and the return spring 222 is located outside the C-shaped groove 21.

The predetermined position is the position where the positioning hole 141 is aligned with the positioning pin 221, and at this time, the positioning pin 221 can be inserted into the positioning hole 141. The photoelectric sensor 23 is preferably an opposed infrared sensor, and its transmitting end and receiving end are respectively arranged on the upper surface and the lower surface of the C-shaped groove 21. When the clamping block 14 moves to the predetermined position, it just blocks the infrared ray and triggers the sensor. As Figure 5 shown in the figure.

[0041] Embodiment 2

[0042] Different from Embodiment 1, in this embodiment, the positioning component 22 is as Figure 7As shown in the figure, it includes an upper positioning module 25 and a lower positioning module 26. The upper positioning module 25 is arranged above the C-shaped groove 21 and includes a positioning pin 221 passing through the upper part of the C-shaped groove 21. A return spring 222 is sleeved on the upper part of the positioning pin 221. The return spring 222 is located outside the C-shaped groove 21. It also includes a traction device 223, and the traction device 223 is connected to the upper end of the positioning pin 221. The lower positioning module 26 has the same structure as the upper positioning module 25 and is symmetrically arranged below the C-shaped groove 21.

[0043] In the foregoing embodiment, a positioning hole 141 matching the positioning pin 221 is provided on the clamping block 14. That is, when the clamping block 14 moves to the positioning component 22 in the C-shaped groove 21, the traction device 223 and the return spring 222 cooperate to drive the positioning pin 221 to insert into the positioning hole 141 to complete the locking of the clamping block 14 and the pull rod 11 with the C-shaped groove 21. The traction device 223 and the return spring 222 cooperate to drive the positioning pin 221 to withdraw from the positioning hole 141 to release the locking of the clamping block 14 and the pull rod 11 with the C-shaped groove 21. In Embodiment 1, the positioning pin 221 passes through the positioning hole 141 for locking. In this Embodiment 2, two positioning pins 221 are inserted into the positioning hole 141 from the upper and lower directions respectively for locking.

[0044] The clamping block 14 is preferably a cylinder. If automatic locking of the clamping block 14 with the C-shaped groove 21 is to be achieved or the positioning pin 221 is to be more easily inserted into the positioning hole 141, chamfers or rounded edges can be provided at the ends of the positioning pin 221 and the positioning hole 141.

[0045] The traction device 223 is preferably an electromagnetic adsorption device, an electric push rod, or a hydraulic or pneumatic drive device.

[0046] Embodiment 3

[0047] Different from Embodiment 1, as Figure 8 shown in the figure, the pull rod driving device 13 in this embodiment is a hydraulic cylinder, and the telescopic rod of the hydraulic cylinder is rotatably connected to the middle area of the pull rod 11. It can also be a cylinder or other driving devices with telescopic rods.

[0048] Embodiment 4

[0049] As Figure 9As shown, different from the foregoing embodiments, the limit component of this embodiment includes a pressure sensor and its control circuit, a lifting stop block 24, and a lifting control module. The lifting control module is connected to the control circuit. The lifting stop block 24 can be inserted into the C-shaped groove 21. The position of the lifting stop block 24 is such that when the lifting stop block 24 is inserted into the C-shaped groove and the latch 14 moves to a predetermined position, the latch 14 contacts the lifting stop block 24. When the latch 14 is in the predetermined position, the positioning pin 221 can be inserted into the positioning hole 141. The pressure sensor is provided on the lifting stop block 24 and is located on the contact surface with the latch 14 of the lifting stop block 24. The contact between the latch 14 and the lifting stop block 24 not only triggers the pressure sensor, but after the control circuit receives the signal from the pressure sensor, it issues an instruction to insert the positioning pin 221 into the positioning hole 141. The lifting stop block 24 can also prevent the latch 14 from moving forward further, so that the two maintain relative position stability during the process of inserting the positioning pin 221 into the positioning hole 141. At least before unlocking, the lifting stop block 24 should be controlled by the lifting control module to retract to allow the latch 14 to smoothly slide out of the C-shaped groove 21.

[0050] The operating principle and process of the embodiment are as Figure 10 shown. The train one T1 equipped with the active component catches up with the train two T2 equipped with the passive component running in the same direction. When the corresponding carriages are approaching, the end of the pull rod on the train one with the latch extends out of the mounting seat, so that the latch enters the C-shaped groove from the rear end of the C-shaped groove of the train two. The latch continues to move forward to the positioning device, and the positioning pin of the positioning device is inserted into the positioning hole of the latch to complete the locking. The two trains should adjust their speeds so that the train one adjusts its speed before locking so that the speeds of the two trains are equal when the latch reaches the positioning device, and also maintain the same speed of the train one and the train two after locking. After the passengers on the trains have exchanged, the positioning pin is withdrawn from the positioning hole, and the train (train one) equipped with the pull rod accelerates. The latch slides along the C-shaped groove and slides out from the front end of the C-shaped groove. After the latch slides out, the pull rod and the latch are retracted into the mounting seat to complete the entire transfer process.

[0051] The locking device M for parallel train carriages of the present invention is applicable to parallel trains with strictly parallel tracks, and the installation quantity can be determined according to the required strength and / or other factors.

[0052] The embodiments described in the present invention are merely descriptions of the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various variations and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the protection scope of the present invention.
