Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A locking device 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 13.
As shown in fig. 1 to 10, according to the locking device 100 of the embodiment of the present invention, the locking device 100 is used in a rail transit system, for example, the rail transit system may be a subway system, a light rail system, and the like, and other components of the rail transit system, such as a train, are well known to those skilled in the art and will not be described in detail herein.
Specifically, the rail transit system includes a ground base 200 and a switch beam 500, the switch beam 500 being movable relative to the ground base 200, one of the switch beam 500 and the ground base 200 being a first load bearing member and the other being a second load bearing member. The ground foundation 200 may be a ground member disposed on the ground, or may be a fixed beam 600 engaged with the switch beam 500.
As shown in fig. 1-5 and 7-10, the locking device 100 is used for implementing position locking on a turnout beam 500 and comprises: a locking head 20 and a lock holder 10, the locking head 20 being adapted to be arranged on a first carrier, the lock holder 10 being adapted to be arranged on a second carrier and being switchable between a locked state and an unlocked state. It can be understood that when the lock head 20 is disposed on the ground base 200, the lock seat 10 is disposed on the switch beam 500 and is switchable between the locking state and the unlocking state; when the lock head 20 is installed on the switch beam 500, the lock seat 10 is installed on the ground base 200 and is switchable between the locking state and the unlocking state, however, it should be understood that the present invention is not limited thereto, and the lock head 20 may also be installed on the trolley 400 fixedly connected to the switch beam 500, and at this time, the lock seat 10 is installed on the ground base 200 and is switchable between the locking state and the unlocking state.
When the lock holder 10 assumes the locked state, the lock holder 10 performs position locking on the lock head 20 reaching a predetermined position (the position where the lock head 20 is located as shown in fig. 2, 5, 8 and 10) to restrict the relative movement of the first bearing member and the second bearing member, and when the lock holder 10 assumes the unlocked state, the lock holder 10 cannot perform position locking on the lock head 20 reaching the predetermined position. It should be noted that the "predetermined position" described herein refers to a position where the lock cylinder 20 can be locked by the lock base 10.
When the lock head 20 moves towards the predetermined position, referring to fig. 1, 4, 7 and 9, the lock head 20 can directly apply force to the lock base 10 to drive the lock base 10 to switch from the locked state to the unlocked state, that is, in the process that the lock head 20 moves towards the predetermined position, once the lock head 20 contacts with the lock base 10, the lock head 20 can directly apply force to the lock base 10 to drive the lock base 10 to switch from the locked state to the unlocked state; when the lock cylinder 20 moves from the predetermined position to a direction away from the predetermined position (as shown in fig. 2, 5, 8 and 10), the lock cylinder 20 cannot drive the lock seat 10 to switch from the locked state to the unlocked state, i.e., once the lock cylinder 20 reaches the predetermined position, the lock cylinder 20 cannot drive the lock seat 10 to switch from the locked state to the unlocked state even if the lock cylinder 20 has a movement tendency and directly applies force to the lock seat 10, but limited by other factors.
Specifically, when the switch beam 500 is switched to the target position, the lock head 20 moves relative to the lock base 10 due to the relative movement between the switch beam 500 and the ground foundation 200, when the lock head 20 contacts the lock base 10, the lock head 20 can directly apply force to the lock base 10 to drive the lock base 10 to switch from the locking state to the unlocking state, when the switch beam 500 is switched to the target position (i.e., the switch beam 500 and the fixed beam 600 can be engaged), the lock head 20 reaches the predetermined position, and simultaneously, the lock base 10 is switched to the locking state to lock the position of the lock head 20 reaching the predetermined position.
Therefore, when the turnout beam 500 is switched in place, the locking device 100 completes the locking action of the turnout beam 500, compared with the related art, the locking device 100 does not need to wait for the turnout beam 500 to be switched in place and then perform the locking action, so that the switching action period of the turnout beam 500 is shortened, the overall efficiency of the turnout beam 500 in operation is improved, and compared with the related art, the locking device 100 does not need to adopt a driving motor and the like to realize locking, so that the manufacturing cost of the locking device 100 and the operation cost of a rail transit system are reduced.
In addition, since the lock cylinder 20 reaching the predetermined position cannot drive the lock base 10 to switch from the locking state to the unlocking state, it is indicated that the lock cylinder 20 having reached the predetermined position cannot actively leave the predetermined position any more, so that the reliability of the locking device 100 in assuming the locking state can be improved, and the locking reliability of the lock cylinder 20 reaching the predetermined position can be ensured.
According to the locking device 100 of the embodiment of the invention, in the switching process of the turnout beam 500, the lock head 20 moves towards the preset position, the lock head 20 can directly apply force to the lock base 10 to drive the lock base 10 to be switched from the locking state to the unlocking state, therefore, when the turnout beam 500 is switched in place, the locking device 100 completes the locking action of the turnout beam 500, the locking time is eliminated, the switching action period time of the turnout beam 500 is shortened, the overall efficiency of the turnout beam 500 in operation is improved, meanwhile, the locking is avoided being realized by adopting a driving motor and the like, and the manufacturing cost of the locking device 100 and the operation cost of a rail transit system are reduced.
In addition, the locking head 20 reaching the preset position cannot drive the lock seat 10 to be switched from the locking state to the unlocking state, so that the reliability of the locking device 100 in the locking state can be improved, the reliability and effectiveness of locking the turnout beam 500 reaching the target position are ensured, the reliability of the train passing through the turnout beam 500 is further ensured, and the driving safety is improved.
In some embodiments of the present invention, the locking device 100 further comprises an unlocking device for driving the lock base 10 to switch from the locking state to the unlocking state. It should be noted that the unlocking device has signal transmission with the control system of the rail transit system, and after the train leaves the turnout beam 500, the control system can drive the lock base 10 to switch from the locking state to the unlocking state through the unlocking device, thereby realizing intelligent unlocking of the locking device 100 and being beneficial to improving the switching efficiency of the rail transit system. For example, the unlocking means may be an electromagnet 5 described below as shown in fig. 3 to 5, a stopper 8 described below as shown in fig. 9 and 10, or the like. Of course, the present application is not limited thereto, and the lock base 10 may be manually (i.e. manually) driven to switch from the locking state to the unlocking state, for example, in case of unlocking requirement or in case of emergency, emergency unlocking of the locking device 100 may be manually achieved.
In some embodiments of the present invention, referring to fig. 1 to 8, the lock base 10 includes a moving member 1 and a reset member 2, the moving member 1 is movable between a locking position and an unlocking position relative to the second bearing member, when the moving member 1 moves to the locking position, the lock base 10 is switched to the locking state, when the moving member 1 moves to the unlocking position, the reset member 2 is used for applying a force to the moving member 1 to push the moving member 1 to be always located at the locking position, that is, when the moving member 1 is not subjected to a force opposite to a force applied by the reset member 2, the moving member 1 is located at the locking position, wherein when the lock head 20 moves toward the predetermined position, the lock head 20 can apply a force to the moving member 1 to move the moving member 1 from the locking position to the unlocking position against a pushing force of the reset member 2.
Therefore, the lock head 20 drives the lock seat 10 to be switched from the locking state to the unlocking state, and meanwhile, after the lock head 20 reaches the preset position, the lock head 20 does not apply force to the moving member 1 any more, so that the moving member 1 is pushed back to the locking position under the action of the reset member 2, and the lock seat 10 is switched to the locking state again to lock the lock head 20. For example, the restoring member 2 may be a spring, a butterfly spring, or the like.
In some alternative embodiments of the present invention, as shown in fig. 6, the moving member 1 has a bevel portion 11, that is, the bevel portion 11 is directly formed on the moving member 1, the bevel portion 11 is disposed obliquely to the moving direction of the moving member 1, and when the lock head 20 moves toward the predetermined position, the lock head 20 can move along the bevel portion 11 to directly push the moving member 1 to move from the locking position to the unlocking position. Therefore, the locking head 20 can directly push the moving member 1 to move from the locking position to the unlocking position. Of course, the invention is not limited to this, and in other embodiments, the moving member 1 may be connected to a connecting member having the inclined surface portion 11, so that the inclined surface portion 11 is attached to the outside of the moving member 1.
Optionally, as shown in fig. 3, a slide rail 6 is disposed on the lock base 10, the moving member 1 is slidably disposed on the slide rail 6, an extending direction of the slide rail 6 is perpendicular or substantially perpendicular to a moving direction of the lock head 20, for example, as shown in fig. 3, a cross section of the slide rail 6 cut along a vertical plane passing through the F2 direction is formed into a convex shape, and a sliding slot adapted to the shape of the slide rail 6 is disposed on the moving member 1, so that a contact area between the moving member 1 and the slide rail 6 in the F2 direction is increased, when the lock head 20 reaches a predetermined position, a locking effect of the moving member 1 on the lock head 20 is improved, and when a train passes through the switch beam 500, vibration in the width direction of the switch beam 500 is reduced, so as to. The F2 direction is the width direction of the switch beam 500, and the F1 direction is the direction perpendicular to the F2 direction.
It should be noted that, when tapered end 20 extrudees moving member 1 and promotes moving member 1 and move on slide rail 6, the inclination of inclined plane portion 11 is rationally set up to the accessible, guarantees that moving member 1 is greater than the frictional force between moving member 1 and lock seat 10 and the elasticity sum of piece 2 that resets along the power of F1 direction to guarantee that tapered end 20 can promote moving member 1, for example, as shown in FIG. 6, the contained angle between inclined plane portion 11 and the F2 direction is alpha, alpha satisfies: alpha is more than or equal to 15 degrees and less than or equal to 30 degrees.
In some alternative embodiments of the present invention, as shown in fig. 6, the moving member 1 has a flat portion 12, that is, the flat portion 12 is directly formed on the moving member 1, the flat portion 12 is disposed parallel to the moving direction of the moving member 1, and when the locking head 20 reaches a predetermined position, the locking head 20 is stopped by the flat portion 12 to achieve position locking of the locking head 20. It can be understood that, after tapered end 20 reached predetermined position, moving member 1 returned to latched position under the effect of piece 2 that resets, tapered end 20 is backstop in order to realize the position locking to tapered end 20 by plane portion 12 simultaneously to be favorable to guaranteeing moving member 1 to the backstop effect of tapered end 20. Of course, the present invention is not limited to this, and in other embodiments, the moving member 1 may be connected to a connecting member having the planar portion 12, so that the planar portion 12 is attached to the outside of the moving member 1.
In some embodiments of the present invention, referring to fig. 1 and 2, the lock base 10 may include a moving member 1 and a reset member 2, the lock base 10 further includes a first fixed member 3 and a second fixed member 4 disposed opposite to each other, the moving member 1 is movable between the first fixed member 3 and the second fixed member 4, and the reset member 2 is connected between the first fixed member 3 and the moving member 1 and pushes the moving member 1 to be always in a locked position against the second fixed member 4 (refer to fig. 2).
It can be understood that, when the locking head 20 moves towards the predetermined position, the locking head 20 can apply force to the moving member 1 to move the moving member 1 from the locking position to the unlocking position against the pushing force of the reset member 2, and then when the locking head 20 reaches the predetermined position, the lock base 10 performs position locking on the locking head 20 reaching the predetermined position. Thereby, the lock cylinder 20 is facilitated to drive the lock housing 10 from the locked state to the unlocked state. And the lock seat 10 has simple structure and low production cost.
In other embodiments of the present invention, referring to fig. 7 and 8, the lock base 10 may further include two moving members 1 and two returning members 2, the two moving members 1 are disposed opposite to each other (for example, the two moving members 1 are disposed opposite to each other in the direction F1 as shown in fig. 7), and the two returning members 2 are respectively connected to a side of the two moving members 1 away from each other to push the two moving members 1 to be in the locked position where the two moving members 1 are always in mutual abutment, that is, when the two moving members 1 are not subjected to the opposite force to the force applied by the two returning members 2, the two moving members 1 are in the locked position where the two moving members 1 are in mutual abutment (refer to fig. 8).
It can be understood that, when the locking head 20 moves towards the predetermined position, the locking head 20 can apply force to the two moving members 1 to make each moving member 1 overcome the thrust of the corresponding reset member 2, so as to make the moving member 1 move from the locking position to the unlocking position, and then when the locking head 20 reaches the predetermined position, the lock base 10 performs position locking on the locking head 20 reaching the predetermined position. Thereby, the locking head 20 facilitates the locking of the lock holder 10 from the locking state to the unlocking state, and the locking and unlocking of the lock holder 10 is made reliable.
In any of the above embodiments, the lock holders 10 may be two and symmetrically disposed at two sides of the predetermined position (for example, as shown in fig. 4 and 7, the two lock holders 10 are symmetrically disposed at two sides of the predetermined position in the direction F2), and when the lock cylinder 20 moves from one of the lock holders 10 toward the other lock holder 10, the lock cylinder 20 pushes one of the lock holders 10 to move from the lock position to the unlock position to reach the predetermined position. Thus, the locking head 20 can enter the predetermined position from different directions, so that the position locking can be applied to the turnout beam 500 which is in the turnout with more than three openings and reaches the middle opening position, for example, in the example shown in fig. 4, the locking head 20 can enter the predetermined position not only from left to right, but also from right to left.
Of course, the present invention is not limited to this, and when the position locking is implemented for the turnout beam 500 reaching the side opening position in any turnout, two lock bases 10 are not needed, for example, in the example shown in fig. 1 and fig. 2, one side of the lock base 10 may be provided with a stop 9, the stop 9 may be stationary relative to the lock base 10 and may be directly fixed on the second bearing member, and when the lock head 20 reaches the predetermined position (refer to fig. 2), the lock head 20 may be stopped between the stop 9 and the moving member 1.
Preferably, the lock cylinder 20 may be formed in a cylindrical shape, so as to facilitate the lock cylinder 20 to apply force to the lock housing 10 to drive the lock housing 10 to realize the state switching. Further, the diameter of the locking head 20 may be slightly smaller than the width of the predetermined position (e.g., width L in fig. 1 and 2), so that the locking head 20 may be clearance-fitted with other components at the predetermined position, thereby improving the reliability of locking.
In some embodiments of the present invention, as shown in fig. 3-5 and 7-8, the locking device 100 may further include: and the electromagnet 5 and the resetting piece 2 are arranged between the moving piece 1 and the electromagnet 5, and when the electromagnet 5 is electrified, the electromagnet 5 attracts the moving piece 1 to compress the resetting piece 2 to move towards the electromagnet 5, so that the moving piece 1 moves from the locking position to the unlocking position.
