[0031] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are for the purpose of explanation only, and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0032] As shown in the drawings, Figure 1 The signal triggering device 1 according to the embodiments of the present disclosure comprises a substrate 11, a triggering plate 12, an elastic member 13 and a position sensing assembly 14, the triggering plate 12 is slidingly arranged on the substrate 11, the elastic member 13 is arranged between the triggering plate 12 and the substrate 11, the elastic member 13 ensures that the distance between the triggering plate 12 and the substrate 11 is not less than a first distance, and the position sensing assembly 14 is arranged on the substrate 11, the position sensing assembly 14 is used to output a triggering signal when the distance between the triggering plate 12 and the substrate 11 is not greater than a second distance, wherein the second distance is less than the first distance.

[0033] It can be understood that when an external object touches the triggering plate 12 and moves the triggering plate 12 in the direction from the triggering plate 12 to the substrate 11, the distance between the triggering plate 12 and the substrate 11 is constantly reduced, and under the action of the elastic member 13, the triggering plate 12 can always abut against the external object, and when the distance between the triggering plate 12 and the substrate 11 is not greater than the second distance, the position sensing assembly 14 outputs a triggering signal, thereby achieving accurate detection of the position of the external object; moreover, due to the arrangement of the elastic member 13, when the external object moves away from the triggering plate 12, the triggering plate 12 can be accurately reset to the initial position, thereby ensuring the accuracy of the signal triggering device 1 when detecting the position of the external object again.

[0034] Therefore, when the signal triggering device 1 is applied to the gate 4 lifting system, the stable abutment of the triggering plate 12 and the gate 4 and the accurate resetting of the triggering plate 12 can be utilized to achieve accurate detection of the position of the gate 4, thereby ensuring the accurate positioning of the grab beam 2 and improving the success rate of the grab beam 2 in grabbing the gate 4.

[0035] It should be noted that the substrate 11 is used to support the triggering plate 12, the elastic member 13, the position sensing assembly 14 and other components, and the specific type of the substrate 11 can be set according to actual needs, which is not limited, for example, the substrate 11 can be a strip-shaped plate structure.

[0036] The trigger plate 12 is used to follow the object such as the gate 4, so as to realize the detection of the position of the object such as the gate 4 by the detection of the position sensing assembly 14. The specific type of the trigger plate 12 can be set according to actual needs, which is not limited. For example, the trigger plate 12 can be a strip-shaped plate structure.

[0037] The substrate 11 and the trigger plate 12 can be arranged in parallel, and the sliding direction of the trigger plate 12 on the substrate 11 is in the thickness direction of the substrate 11.

[0038] The elastic member 13 is used to exert a force on the trigger plate 12 away from the substrate 11. When the distance between the object such as the gate 4 and the substrate 11 deviates, the elastic force of the elastic member 13 can ensure the stable abutment of the trigger plate 12 and the object such as the gate 4, thereby compensating for the distance deviation between the object such as the gate 4 and the substrate 11. At the same time, the elastic force of the elastic member 13 can also avoid the collision of the object such as the gate 4 to the substrate 11, the position sensing assembly 14 and other components, thereby ensuring the safety and stability of the signal triggering device 1. The specific type of the elastic member 13 can be set according to actual needs, which is not limited. For example, the elastic member 13 can be a coil spring.

[0039] The specific values of the first distance and the second distance can be set according to actual needs, which is not limited.

[0040] The position sensing assembly 14 is used to output a trigger signal when the distance between the trigger plate 12 and the substrate 11 is not greater than the second distance. The specific type of the position sensing assembly 14 can be set according to actual needs, which is not limited.

[0041] As shown in FIG. 1, Figure 1 In some embodiments, the position sensing assembly 14 includes a linkage rod 141 and a position sensor 142. The linkage rod 141 is arranged on the trigger plate 12, and one end of the linkage rod 141 away from the trigger plate 12 penetrates to the side of the substrate 11 away from the trigger plate 12. The position sensor 142 is arranged on the side of the substrate 11 away from the trigger plate 12. The position sensor 142 is used to sense the one end of the linkage rod 141 away from the trigger plate 12 when the distance between the trigger plate 12 and the substrate 11 is not greater than the second distance, and output a trigger signal.

[0042] Understandably, when an external object touches the trigger plate 12 and causes it to move along the direction from the trigger plate 12 to the substrate 11, the distance between the trigger plate 12 and the substrate 11 continuously decreases, and the linkage rod 141 moves closer to the position sensor 142 as the trigger plate 12 moves. At the same time, under the action of the elastic element 13, the trigger plate 12 can always be in contact with the external object. When the distance between the trigger plate 12 and the substrate 11 is not greater than the second distance, the position sensor 142 senses the end of the linkage rod 141 that is away from the trigger plate 12 and outputs a trigger signal, thereby achieving accurate detection of the position of the external object. Moreover, due to the setting of the elastic element 13, when the external object moves away from the trigger plate 12, the trigger plate 12 and the linkage rod 141 can accurately reset to the initial position, thereby ensuring the accuracy of the signal triggering device 1 when detecting the position of the external object again.

[0043] It should be noted that the arrangement between the linkage 141 and the substrate 11 can be set according to actual needs and there are no restrictions. For example, the substrate 11 is provided with a sliding sleeve, and the linkage 141 slides through the sliding sleeve.

[0044] The axial direction of the linkage 141 can be located in the thickness direction of the substrate 11, that is, the central axis of the linkage 141 is perpendicular to the substrate 11 and the trigger plate 12 respectively. When the elastic element 13 is a helical spring, the helical spring is sleeved on the linkage 141, and the central axis of the helical spring coincides with the central axis of the linkage 141.

[0045] The position sensor 142 is used to detect the position of the end of the linkage 141 away from the trigger plate 12 and output a trigger signal. The specific type of the position sensor 142 can be set according to actual needs and there is no limitation on it.

[0046] like Figure 1 As shown, in some embodiments, the position sensor 142 includes a magnet 1421 and a magnetic proximity switch 1422. The magnet 1421 is disposed at the end of the linkage 141 away from the trigger plate 12, and the magnetic proximity switch 1422 is disposed on the side of the substrate 11 away from the trigger plate 12. The magnetic proximity switch 1422 and the magnet 1421 are disposed opposite to each other. When the distance between the trigger plate 12 and the substrate 11 is not greater than a second distance, the magnetic proximity switch 1422 senses the magnet 1421 and outputs a trigger signal.

[0047] It can be understood that when the external object touches the trigger plate 12 and moves the trigger plate 12 in the direction from the trigger plate 12 to the base plate 11, the distance between the trigger plate 12 and the base plate 11 is continuously reduced, and the magnet 1421 continuously approaches the magnetic proximity switch 1422 with the movement of the trigger plate 12, and under the action of the elastic member 13, the trigger plate 12 can always abut against the external object, when the distance between the trigger plate 12 and the base plate 11 is not greater than the second distance, the magnetic proximity switch 1422 senses the magnetic field of the magnet 1421 and outputs a trigger signal, thereby realizing accurate detection of the position of the external object; and due to the arrangement of the elastic member 13, when the external object moves away from the trigger plate 12, the trigger plate 12 and the magnet 1421 can be accurately reset to the initial position, thereby ensuring the accuracy of the signal triggering device 1 when detecting the position of the external object again.

[0048] Wherein, through the cooperation of the magnet 1421 and the magnetic proximity switch 1422, not only the accurate detection of the position of the external object by the signal triggering device 1 is ensured, but also the collision contact between components is avoided, thereby effectively prolonging the service life of the signal triggering device 1 and improving the stability of the signal triggering device 1.

[0049] It should be noted that the specific type of the magnet 1421 can be set according to actual needs, which is not limited, for example, the magnet 1421 can be a T-shaped structure, and the magnetic pole direction of the magnet 1421 is in the axial direction of the linkage rod 141.

[0050] The magnetic proximity switch 1422 is a kind of proximity switch, which detects the position change of a magnetic object by using electromagnetic principle, and converts non-electric quantity or electromagnetic quantity into desired electric signal, so as to achieve the purpose of control. The specific type of the magnetic proximity switch 1422 can be set according to actual needs, which is not limited, for example, the magnetic proximity switch 1422 can include a NOT gate, an inverter, a chip, etc.

[0051] As shown in FIG. 1, Figure 1 As shown in FIG. 1,

[0052] It can be understood that through the arrangement of the magnetic proximity switch 1422, the magnetic field generated by the magnet 1421 can be avoided to affect the action of the linkage rod 141, the trigger plate 12 and other components, so as to enable the magnetic proximity switch 1422 to stably detect the position of the linkage rod 141 by using the magnet 1421 while ensuring the stable action of the trigger plate 12, thereby ensuring the accurate detection of the position of the external object by the signal triggering device 1.

[0053] It should be noted that the specific type of the magnetic shielding component 1423 can be set according to actual needs, and there are no restrictions on it. For example, the material of the magnetic shielding component 1423 can be silicon steel, etc.

[0054] like Figure 1 As shown, in some embodiments, the signal triggering device 1 further includes a first end plate 15 and a second end plate 16. The first end plate 15 is disposed on the side of the substrate 11 near the trigger plate 12, and a first groove 151 is provided on the first end plate 15. The second end plate 16 is disposed on the side of the substrate 11 near the trigger plate 12, and a second groove 161 is provided on the second end plate 16. A receiving space is formed between the first end plate 15 and the second end plate 16. The trigger plate 12 is located in the receiving space, and one end of the trigger plate 12 is slidably disposed in the first groove 151, while the other end of the trigger plate 12 away from the first groove 151 is slidably disposed in the second groove 161.

[0055] It is understandable that the first end plate 15 and the second end plate 16 are used to provide stable support for the trigger plate 12, and the first slide groove 151 and the second slide groove 161 are used to enable the trigger plate 12 to slide stably on the base plate 11, thereby ensuring that the position sensor 142 can accurately detect the position of the linkage rod 141.

[0056] The elastic element 13 ensures that the trigger plate 12 can always abut against the end of the first groove 151 away from the substrate 11 and the end of the second groove 161 away from the substrate 11 when no external force is applied. This ensures that the signal triggering device 1 can accurately detect the position of the external object by using the movement of the trigger plate 12 and the external object.

[0057] It should be noted that the specific types of the first end plate 15 and the second end plate 16 can be set according to actual needs, and there is no restriction on this. For example, the first end plate 15 and the second end plate 16 are plate structures, and the first end plate 15 and the second end plate 16 are respectively arranged parallel to the connecting rod 141.

[0058] The first end plate 15 and the second end plate 16 can both be vertically mounted on the base plate 11. The first end plate 15 and the second end plate 16 have the same structure and are symmetrically distributed along the central axis of the linkage 141.

[0059] The specific type of the first sliding groove 151 and the second sliding groove 161 can be set according to actual needs, and no limitation is made thereto. For example, a first guide rail is arranged on the groove wall of the first sliding groove 151, a second guide rail is arranged on the groove wall of the second sliding groove 161, a first rail groove is arranged at one end of the trigger plate 12, a second rail groove is arranged at the other end of the trigger plate 12, the first guide rail is slidingly arranged in the first rail groove, and the second guide rail is slidingly arranged in the second rail groove, so as to achieve the sliding arrangement of the trigger plate 12 on the first end plate 15 and the second end plate 16.

[0060] The size of the first sliding groove 151 and the second sliding groove 161 is set to be able to meet the movement of the trigger plate 12 relative to the base plate 11, that is, the length of the first sliding groove 151 and the second sliding groove 161 should be greater than the difference between the first distance and the second distance.

[0061] As shown in FIG. 1, Figure 1 In some embodiments, the signal triggering device 1 further comprises an axial limiting assembly 17, which comprises a limiting pin 171 and a plurality of limiting blocks 172. The plurality of limiting blocks 172 are arranged on the first end plate 15 and / or the second end plate 16, respectively, and a limiting groove 173 is formed between the plurality of limiting blocks 172. The limiting pin 171 is arranged on the trigger plate 12 and located in the limiting groove 173.

[0062] It can be understood that, since the limiting pin 171 is limited in the limiting groove 173, the problem of damage to the signal triggering device 1 caused by the excessive movement of the linkage rod 141 and the trigger plate 12 in the direction from the trigger plate 12 to the base plate 11 is avoided, and the problem of the signal triggering device 1 being unable to detect the position of the external object caused by the excessive movement of the linkage rod 141 and the trigger plate 12 in the direction from the base plate 11 to the trigger plate 12 is also avoided. Therefore, through the cooperation of the limiting pin 171 and the limiting groove 173, the accurate detection of the external object by the signal triggering device 1 is ensured.

[0063] It should be noted that the number and arrangement position of the limiting blocks 172 can be set according to actual needs, and no limitation is made thereto. For example, the limiting blocks 172 can be two, which are arranged on the first end plate 15 or the second end plate 16, and a limiting groove 173 is formed between the two limiting blocks 172. The limiting blocks 172 can be four, of which two limiting blocks 172 are arranged on the first end plate 15 and form a first limiting groove, and the other two limiting blocks 172 are arranged on the second end plate 16 and form a second limiting groove. A first limiting pin and a second limiting pin are arranged on the trigger plate 12, the first limiting pin is arranged in the first limiting groove, and the second limiting pin is arranged in the second limiting groove.

[0064] The specific type of the limiting groove 173 can be set according to actual needs and there is no restriction. The size of the limiting groove 173 should be able to meet the movement of the linkage rod 141 relative to the base plate 11, that is, the length of the limiting groove 173 should be greater than the difference between the first distance and the second distance.

[0065] like Figure 1 As shown, in some embodiments, the signal triggering device 1 further includes a radial limiting component 18, which includes a limiting sleeve 181. The limiting sleeve 181 is disposed on the substrate 11 and is slidably sleeved on the connecting rod 141.

[0066] It is understandable that, since the limiting sleeve 181 is slidably sleeved on the connecting rod 141, it avoids radial offset when the connecting rod 141 moves in the direction from the trigger plate 12 to the base plate 11 or in the direction from the base plate 11 to the trigger plate 12, thereby ensuring the stable movement of the connecting rod 141 and thus ensuring the accurate detection of external objects by the signal triggering device 1.

[0067] It should be noted that the specific type of the limiting sleeve 181 can be set according to actual needs and is not limited thereto. The limiting sleeve 181 can be a sleeve structure, and the limiting sleeve 181 is set on the side of the substrate 11 near the trigger plate 12. The length of the limiting sleeve 181 should be sufficient to allow the trigger plate 12 to move relative to the substrate 11, so as to avoid obstructing the trigger plate 12.

[0068] like Figure 2 As shown in the present disclosure, an embodiment of the present disclosure also proposes a gate 4 lifting system, including a grab beam 2 and at least one signal triggering device 1 as described in the present disclosure, wherein the signal triggering device 1 is disposed at the grab end of the grab beam 2.

[0069] Understandably, when the grab beam 2 moves the signal triggering device 1 and the gate 4 touches the trigger plate 12 and moves the trigger plate 12 along the direction from the trigger plate 12 to the base plate 11, the distance between the trigger plate 12 and the base plate 11 continuously decreases. Under the action of the elastic element 13, the trigger plate 12 can always abut against the gate 4. When the distance between the trigger plate 12 and the base plate 11 is not greater than the second distance, the position sensing component 14 outputs a trigger signal, thereby achieving accurate detection of the gate 4. Moreover, due to the setting of the elastic element 13, when the grab beam 2 moves the signal triggering device 1 away from the gate 4, the trigger plate 12 can accurately reset to the initial position, thereby ensuring the accuracy of the signal triggering device 1 when detecting the position of the gate 4 again.

[0070] Therefore, by using at least one signal triggering device 1, the position of the gate 4 can be accurately detected, thereby ensuring the precise positioning of the grabbing beam 2 and improving the success rate of the grabbing beam 2 in grabbing the gate 4.

[0071] It should be noted that the grab beam 2 can include one signal triggering device 1 or multiple signal triggering devices 1, and the number of signal triggering devices 1 is not limited, and when the grab beam 2 includes multiple signal triggering devices 1, the multiple signal triggering devices 1 can be used to detect the position of the same gate 4 at the same time.

[0072] The movement control of the grab beam 2 can be realized by a controller. For example, the signal output end of the magnetic proximity switch 1422 is connected to the signal input end of the controller, and the signal output end of the controller is connected to the driving end of the grab beam 2. The controller controls the movement of the grab beam 2 and the grabbing of the gate 4 according to the trigger signal output by the magnetic proximity switch 1422.

[0073] The movement of the grab beam 2 can be realized by an external hoisting device. The specific type of the hoisting device can be set according to actual needs, and the type of the hoisting device is not limited. For example, the hoisting device can be a crane.

[0074] As shown in Figure 2 In some embodiments, the first end plate 15 of the signal triggering device 1 is provided with a first pin hole 152, the second end plate 16 of the signal triggering device 1 is provided with a second pin hole 162, the first pin hole 152 and the second pin hole 162 are oppositely arranged, and the gate 4 lifting system further includes a pin rod 3. The pin rod 3 is used to sequentially penetrate the first pin hole 152, a third pin hole 41 on the gate 4, and the second pin hole 162.

[0075] It can be understood that when the position sensing assembly 14 of the signal triggering device 1 outputs a trigger signal, the first pin hole 152, the third pin hole 41 on the gate 4, and the second pin hole 162 are in an aligned state. At this time, the pin rod 3 can sequentially pass through the first pin hole 152, the third pin hole 41 on the gate 4, and the second pin hole 162, so as to realize the grabbing of the gate 4 by the grab beam 2, and further enable the whole to realize the lifting of the gate 4 by the movement of the grab beam 2, thereby meeting the use requirement.

[0076] It should be noted that the driving of the pin rod 3 can be set according to actual needs, and the type of the driving of the pin rod 3 is not limited. For example, the driving of the pin rod 3 can be realized by a hydraulic system.

[0077] The pin rod 3 can be arranged perpendicularly to the first end plate 15 and the second end plate 16, and the pin rod 3 can be arranged in parallel to the base plate 11.

[0078] As shown in Figure 2 In some embodiments, the grab beam 2 is provided with at least one third sliding groove 21, and the first end plate 15 and the second end plate 16 are respectively connected to the groove wall of the third sliding groove 21 in a sliding manner.

[0079] It can be understood that, due to the sliding connection of the first end plate 15 and the second end plate 16 with the groove wall of the third sliding groove 21 respectively, the signal triggering device 1 can be adjusted in position on the grab beam 2, and then the grab beam 2 can grab different types of gates 4, thereby effectively improving the versatility and flexibility of the whole, and making the use more convenient.
