Example (b):
referring to fig. 1 to 7, a self-resetting type displacement device designed for an automatic vehicle-based transponder according to a preferred embodiment of the present invention includes a base plate 1, a counterweight mounting plate 2, a rotating element 3 and a rotating driving element 4. Wherein, base plate 1 is fixed in the below of rail 6, and rotating assembly 3 rotates and connects on base plate 1, and it can realize rotary motion under the drive of rotary drive subassembly 4, and then realizes the switching of operating condition and fold condition.
In a working state (namely an initial state), the rotating assembly 3 is driven by the rotating driving assembly 4 to rotate, so that the carrying assembly 5 rotates to a position between two steel rails 6 from the bottoms of the steel rails 6, namely the signal transponder 503 extends into a certain distance above the ground of the overhaul trench, and therefore guarantee is provided for accurate warehousing and parking of the fully-automatic running vehicle, and accurate parking of the fully-automatic running vehicle in a vehicle base is realized; under fold condition, set up in the central point that carries on subassembly 5 of 3 tip of rotating assembly is kept away from the maintenance trench and puts to this normal work that realizes overhauing the trench ensures that maintenance operation personnel and automatic maintenance robot can be current smoothly at the maintenance trench.
In particular, the base plate 1 in the preferred embodiment is a plate-like structure that is disposed at the bottom of the rails 6 for providing support for the placement of other components of the indexing device. In the preferred embodiment, the base plate 1 is fixed to the bottom of the rail 6 by two fasteners 101 respectively disposed on two lateral sides of the rail 6, and the fasteners 101 are in an "L" shape, one end of each fastener is fixed to the base plate 1, and the other end of each fastener is fastened to the bottom of the rail 6. Through the arrangement, the base plate 1 can be arranged, and the interference to a track running area after the base plate 1 is arranged can be avoided.
Further, other components of the displacement device in the preferred embodiment are disposed below the base plate 1, wherein a rotating member 102 is disposed on the bottom surface of the base plate 1 near one end of the manhole corresponding to the rotating assembly 3 for rotatably connecting the end of the rotating assembly 3. In actual implementation, the rotating member 102 is a hinged member as shown in fig. 4; it is obvious, however, that the above-mentioned rotating member 102 may be replaced by other configurations in the prior art according to actual needs, as long as the rotation control of the end of the rotating assembly 3 is satisfied.
Meanwhile, in a preferred embodiment, the rotating assembly 3 includes a first rotating lever 301 and a second rotating lever 302, and one end of the first rotating lever 301 is connected to the rotating member 102, so that a driving process of rotating around the end portion can be realized under the rotation of the rotating member 102. Accordingly, one end of the second rotating rod 302 is fixedly connected to one side of the first rotating rod 301, and can rotate synchronously with the first rotating rod 301.
In practical arrangement, the second rotating lever 302 is made to be in a horizontal state when the rotating assembly 3 is in the folded state, and is made to be in a vertical state when the rotating assembly 3 is in operation, i.e. the rotating assembly 3 is rotated by 90 ° when being converted from the folded state to the operating state. Obviously, the setting angle can be adjusted according to actual needs, which can be determined according to specific situations.
Further, a guide 303 is provided on the second rotating lever 302 along the length direction thereof, and a slider 304 is provided corresponding to the guide 303, the slider 304 being fitted on the guide 303 and being reciprocally slidable along the axis of the guide 303. In practical arrangement, the combination of the sliding member 304 and the guiding member 303 may be a combination of a sliding block and a sliding rail, as shown in fig. 1, or a combination of a guide groove and a sliding pin, which may also be preferable according to practical situations.
Preferably, a limiting member 305 is disposed on an end of the first rotating lever 301 or the second rotating lever 302 close to the base plate 1, and correspondingly, a blocking member 306 is disposed on a bottom of the base plate 1, so that the limiting member 305 just matches and abuts against the blocking member 306 after the first rotating lever 301 rotates from the folded state to the position. For example, in the preferred embodiment shown in fig. 2, the limiting member 305 and the blocking member 306 are respectively of a plate-like structure extending horizontally, the limiting member 305 is of a plate-like structure extending longitudinally along the steel rail 6, and the blocking member 306 is of a plate-like structure extending transversely along the steel rail 6, which are abutted and matched just after the rotating assembly 3 is rotated in place, so as to avoid over-rotation of the rotating assembly 3 and ensure that the transponder 503 on the carrying assembly 5 can be rotated in place accurately. Obviously, in practical arrangement, another blocking member may be disposed on the bottom surface of the other end of the base plate 1 for limiting the blocking when the rotating assembly 3 is retracted.
Further preferably, when the blocking member 306 is actually disposed, one end of the blocking member 306 abutting against the limiting member 305 may be set as an elastic end, so that the contact between the blocking member 306 and the limiting member 305 may be buffered to some extent. For example, the blocking member 306 is configured as a spring damper to ensure that the rotating assembly 3 can be effectively damped after rotating to the proper position, thereby avoiding over-rotation of the rotating assembly 3. Of course, it is understood that the spring damper and the blocking member 306 may be provided at the same time, and the blocking member provided when the corresponding rotating assembly 3 is retracted may be provided in the above-described damping manner.
In addition, in practical application, a sensing assembly can be provided for the working state and/or the folding state of the rotating assembly 3 to display whether the rotating assembly 3 is rotated or retracted. And preferably, the alarm components are arranged corresponding to the sensing components, once the sensing components do not move in place, the alarm can be given through the corresponding alarm components, and then the maintainers can perform corresponding control and adjustment operation.
Specifically, in a preferred embodiment, a pressure sensor is disposed at the bottom of the substrate 1 with respect to the limiting member 305, so that after the rotating assembly 3 rotates to the right position, the limiting member 305 may abut against the pressure sensor, and whether the rotating assembly 3 rotates to the right position is determined by the state of the pressure sensor. Meanwhile, another pressure sensor may be disposed below the substrate 1 with respect to the connecting rod 501 of the rotating assembly 3 or the carrying assembly 5, so that after the rotating assembly 3 is retracted to the proper position, the rotating assembly 3 or the connecting rod 501 may correspondingly abut against the pressure sensor, and it is determined whether the rotating assembly 3 is retracted to the proper position.
Obviously, the above sensing assembly can be implemented in other forms according to the actual design and application requirements, for example, in another preferred embodiment, optical sensors are respectively disposed on the rotating assembly 3 and the substrate 1, and one of the optical sensors emits sensing light, and the other optical sensor receives the sensing light, so as to determine whether the rotating assembly is rotated in place. Similarly, a similar optical sensor may be provided corresponding to the retraction of the rotating assembly 3, so as to determine whether the folded state is in place.
Further, referring to fig. 1 to 5, in the preferred embodiment, a rotation driving assembly 4 is further disposed corresponding to the rotation assembly 3, and is mainly used for the rotation driving and the rotation retracting of the rotation assembly 3. The drive component comprises a counterweight 401 and a drive rope 402, and a counterweight mounting plate 2 is arranged corresponding to the drive component, the plate surface of the counterweight mounting plate 2 is arranged vertically, and the plate surface of the counterweight mounting plate 2 is preferably perpendicular to the longitudinal direction of the steel rail 6, namely the plate surface of the steel rail 6 extends in the transverse direction of the steel rail 6.
Further specifically, the top of the counterweight mounting plate 2 is fixed on the bottom surface of the base plate 1, and at least two pulleys are provided on a side thereof close to the rotating assembly 3 for matching the operation of the driving rope 402. In the preferred embodiment, the number of the pulleys is 3, that is, the first pulley 201, the second pulley 202, the third pulley 203, the second pulley 202 and the third pulley 203 are arranged at one end of the counterweight mounting plate 2, the first pulley 201 is arranged at the other end of the counterweight mounting plate 2, then one end of the driving rope 402 is matched with the counterweight 401, the other end of the driving rope is wound around the bottom of the second pulley 202 after being wound above the first pulley 201, and is matched and connected on the sliding member 304 after being wound above the third pulley 203.
Through the arrangement, the counterweight 401 can pull the driving rope 402 to move under the action of self weight, and then the unlocking rotating assembly 3 is driven to a working state from a folding state. Obviously. In actual installation, the driving rope 402 can be driven to rotate only by connecting one end of the driving rope to the end of the second rotating rod 302, so that the sliding member 304 can be regarded as a connecting member fixed to the end of the guiding member 303. Although the above arrangement can satisfy the actual driving requirement, the length of the driving rope 402 is long, and the driving stroke of the counterweight 401 is also long. Therefore, it is also preferable to attach the end of the drive cord 402 to the movable slider 304 when actually setting up.
Further, the retracting member in the preferred embodiment is disposed at the bottom of the end of the base plate 1 facing away from the rotator 102 for retracting the rotating assembly 3 from the working state. In practice, the retraction member may be provided in different forms, depending on the design requirements.
For example, in a preferred embodiment, the retracting means includes a servo motor 403, a retracting wheel 404, and a retracting rope 405, as shown in fig. 2, one end of the retracting rope 405 is connected to the back of the first rotating lever 301, and the other end thereof is connected to the retracting wheel 404. Meanwhile, the retracting wheel 404 is coaxially matched with the output shaft of the servo motor 403, the retracting rope 405 can be wound back on the retracting wheel 404 through the work of the servo motor 403, further, the retracting of the rotating assembly 3 is realized, and after the rotating assembly 3 is retracted in place, the rotating assembly 3 can be kept in a folded state only by locking the servo motor 403. Once the servo motor 403 is unlocked, the rotating assembly 3 can be rapidly extended by the counterweight 401, and thus self-reset.
Obviously, the retraction member may be provided in other forms than the above, for example, in another preferred embodiment, the retraction member is provided in the form of a telescopic cylinder, one end of which is hinged to the bottom of the base plate 1, and the end of the output shaft thereof is hinged to the back of the first rotating rod 301, and the retraction of the rotating assembly 3 can be achieved by the retraction of the output shaft. It is clear that when the retraction member is provided in the above-described manner, it may also essentially function as a drive member, i.e. by extension of the output shaft, to switch the rotation assembly 3 from the folded state to the operative state.
Further, a mounting unit 5 for mounting the transponder 503 is provided on the rotating unit 3. In a preferred embodiment, the carrying assembly 5 comprises a connecting rod 501 and a mounting seat 502, one end of the connecting rod 501 is connected to the first rotating rod 301, the end of the other end is provided with the mounting seat 502, and the signal transponder 503 is arranged on the mounting seat 502. Preferably, when the rotating assembly 3 is rotated to the position, the connecting rod 501 is just in the horizontal state, and the mounting seat 502 supports the signal transponder 503 at the middle position of the two rails 6 (the top surface of the signal transponder 503 is lower than the rail surface height of the two rails 6 by a certain distance, usually 120mm), and the top surface of the signal transponder 503 is horizontally arranged. Accordingly, when the rotating assembly 3 is in the folded state, the connecting rod 501 is preferably in the vertical state, and the top surface of the transponder 503 is in the vertical state, as shown in fig. 7.
The preferred embodiment of the self-resetting indexing device is shown in its operative configuration in figure 2 and in its collapsed configuration in figure 7. The working process is as follows:
when the displacement device needs to be switched from the folded state to the working state, the rotating assembly 3 can be driven by the counterweight 401 to realize self-resetting and rotate to the working state only by releasing the locking of the servo motor 403. After the device is stretched out in place, whether the device is stretched out in place or not can be judged through the corresponding sensing assembly on the displacement device.
On the contrary, when the position changing device needs to be switched from the working state to the folding state, only the servo motor 403 needs to be controlled to work, the retracting rope 405 is retracted to the retracting wheel 404, at the moment, the second rotating rod 302 rotates to pull the driving rope 402, so that the counterweight 401 is lifted by a certain height under the driving of the driving rope 402 until the corresponding sensing component on the position changing device judges that the device is retracted to the place, and then the servo motor 403 is locked, and the position changing device can be locked in the folding state.
