[0033] In some embodiments of the application, a throwing device is provided, which can realize the synchronous release of the main laying component and its laying auxiliary component.

[0034] In some embodiments, the main laying component is an anchor body, and the laying auxiliary component is an anchor claw connected to the anchor body.

[0035] In some embodiments, the throwing device comprises:

[0036] The support body 100 constitutes the support frame of the whole throwing device, which bears and supports the whole throwing device.

[0037] The guide portion 134 and the clamping portion 143 are formed in the inside of the support body 100.

[0038] The driving device is fixed on the support body 100 and comprises:

[0039] The release element 200 is used to connect with the main body of the laying device and has a locking position and an unlocking position.

[0040] The driving element 300 drives the release element 200 to act to release the main laying component and switches the release element 200 between the locking position and the unlocking position.

[0041] The driving element 300 is connected with the release element 200, and the driving element 300 drives the release element 200 to act when the driving element 300 acts, and the release element 200 is separated from the release element 200 by the action of the release element 200, so as to release the main laying component.

[0042] Meanwhile, the release element 200 also has a locking position and an unlocking position, which are mainly used for locking or unlocking the transmission element 400 in contact therewith.

[0043] The transmission element 400 is movably arranged in the guide portion 134 and abuts against the side wall of the release element 200.

[0044] The guide portion 134 arranged in the support body 100 can guide the moving route of the transmission element 400, so that the transmission element 400 moves along the set route, thereby ensuring the contact between the transmission element 400 and the release element 200.

[0045] When the release element 200 is driven by the driven element 300, it can switch between the locking position and the unlocking position. When it switches to the locking position, the transmission element 400 is locked, and when it switches to the unlocking position, the locking effect of the transmission element 400 is released.

[0046] The locking member 500 is rotatably connected to the support body 100 and arranged in the clamping portion 143 at one end and abuts against the limit portion through the transmission element 400 at the other end.

[0047] The transmission element 400 is used to realize the unlocking or locking of the locking member 500.

[0048] When the transmission element 400 contacts the locking member 500, the locking member 500 is abutted against the limit portion through the transmission element 400, and the end of the locking member 500 in the clamping portion 143 and carrying the auxiliary element cannot be separated from the clamping portion 143.

[0049] When the transmission element 400 no longer abuts against the end of the locking member 500, the limit of the locking member 500 is eliminated, and the other end of the locking member 500 is driven to rotate to separate from the auxiliary element under the gravity of the auxiliary element, thereby releasing the auxiliary element.

[0050] In some embodiments of the present application, the release element 200 is a release rod, the transmission element 400 is a transmission rod, the contact end of the transmission element 400 with the locking member 500 is an arc-shaped curved surface 410, and the locking member 500 is provided with an arc-shaped groove 510 matched with the arc-shaped curved surface 410.

[0051] When the release element 200 is in the locking position, the arc-shaped curved surface 410 of the transmission element 400 is clamped into the arc-shaped groove 510. Through the matched structure of the arc-shaped curved surface 410 and the arc-shaped groove 510, not only can the two be locked firmly, but also the transmission element 400 and the release element 200 can be separated conveniently.

[0052] Specifically, when the release element 200 is in the locking position, the release element 200 abuts against the transmission element 400 to limit the transmission element 400, and the transmission element 400 abuts against the locking component 500 to limit the locking component 500 so that the locking component 500 can bear and fix the laying auxiliary element supported thereon.

[0053] When the release element 200 is in the unlocking position, the cooperation position of the transmission element 400 and the release element 200 changes, the transmission element 400 moves away from the locking component 500 and releases the limitation of the locking component 500, and the locking component 500 rotates to be separated from the clamping portion 143 and the laying auxiliary element.

[0054] The unloading device in the embodiment is provided with the driving element 300 and the release element 200 cooperating with the driving element 300, the release element 200 is driven to act by the driving element 300, the release element 200 is separated from the main laying component connected thereto, and the release of the main laying component is realized.

[0055] When the release element 200 acts, it also switches between the locking position and the unlocking position, when the release element 200 is in the unlocking position, the transmission element 400 in contact with the release element 200 is separated from the locking component 500, the locking component 500 is separated from the clamping portion 143, the release of the laying auxiliary element is realized, and the release of the main laying component and the laying auxiliary element is realized by the driving element 300, the release element 200 and the locking component 500 are simultaneously driven to act, and the synchronous release of the main laying component and the laying auxiliary element is realized, and the release efficiency is improved.

[0056] When the release is performed, the power consumption is only the power required during the period when the release element 200 is driven by the driving element 300 to rotate from the locking position to the unlocking position, compared with the existing electromagnetic adsorption release mechanism, the driving element 300 does not need to be continuously powered, and the power consumption is small.

[0057] In some embodiments of the present application, the release element 200 includes a body portion 210 and a protruding portion 220 formed on the body portion 210.

[0058] When the release element 200 is in the locking position, the transmission element 400 abuts against the protruding portion 220;

[0059] When the release element 200 is in the unlocking position, the transmission element 400 abuts against the body portion 210.

[0060] When the release element 200 is driven to act, the position of the release element 200 changes, and the contact position of the release element 200 and the transmission element also changes.

[0061] When the transmission member 400 and the protruding part 220 are in contact and fit, the protruding part 220 of the protruding body part 210 can abut against the transmission member 400 to limit the transmission member 400, and the transmission member 400 can abut against the locking part 500 to limit the locking part 500. At this time, the main dispensing part is connected with the releasing element 200, and the releasing element 200 is connected with the support body 100 through the driving element 300, and the main dispensing part is supported by the support body 100.

[0062] The dispensing auxiliary part is supported by the locking part 500 which is locked and limited at both ends.

[0063] When the releasing element 200 is switched to the unlocking position, the transmission member 400 abuts against the body part 210. When the contact position of the transmission member 400 and the releasing element 200 is shifted from the protruding part 220 to the body part 210, the transmission member 400 moves along the moving direction of the guide part 134, i.e. moves towards the body part 210. When the transmission member 400 moves towards the body part 210, the transmission member 400 moves away from the locking part 500, and the locking part 500 is separated from the transmission member 400. The locking part 500 is released from the limiting, and the locking part 500 rotates to be separated from the dispensing auxiliary part.

[0064] The cross-sectional shape of the body part 210 can be square, circular or polygonal, etc. The protruding part 220 is connected to the side wall of the body part 210. In order to facilitate the smooth sliding of the transmission member 400 between the protruding part 220 and the body part 210, the protruding part 220 and the body part 210 are smoothly connected, and the outer side surface of the protruding part 220 is a smooth curved surface.

[0065] In some embodiments of the present application, the protruding part 220 is a semicircular arc, and the body part 210 is a rectangle.

[0066] In some embodiments of the present application, the driving element 300 is a rotating driving mechanism for driving the releasing element 200 to rotate, and the protruding part 220 is a protrusion arranged in the circumferential direction of the body part 210.

[0067] The rotating driving mechanism can be a rotating motor, and the protruding part 220 and the body part 210 are smoothly connected.

[0068] When the releasing element 200 rotates in the circumferential direction, the contact position of the transmission member 400 and the releasing element 200 is switched between the protruding part 220 and the body part 210.

[0069] When the releasing element 200 rotates to the position where the protruding part 220 and the transmission member 400 are in contact, the transmission member 400 is locked, and the locking part 500 is locked by the transmission member 400.

[0070] When the release element 200 rotates to contact the body part 210 and the transmission part 400, the transmission part 400 is unlocked, and the locking part 500 is unlocked.

[0071] A threaded part 230 is arranged at the bottom of the release element 200 and is threadedly connected with the main distribution part.

[0072] The threaded part 230 is arranged with threads on the main distribution part to achieve the threaded connection of the release element 200 and the main distribution part.

[0073] A rotation limiting part 110 is arranged on the bracket body 100 and cooperates with the main distribution part to limit the linear movement of the main distribution part.

[0074] The rotation limiting part 110 is a linear limiting groove or a linear limiting protrusion, which is used to cooperate with the main distribution part, and correspondingly, a linear limiting protrusion or a linear limiting groove can be arranged on the main distribution part to cooperate with the linear limiting groove or the linear limiting protrusion.

[0075] When the release element 200 rotates, the main distribution part threadedly connected with the release element 200 moves linearly in a spiral manner, and the main distribution part is limited to move linearly in the up-down direction by the structure of the rotation limiting part 110. Thus, when the driving element 300 rotates, the release element 200 is driven to rotate to drive the main distribution part to move up and down, and then the main distribution part is separated from the release element 200 to be released.

[0076] When the release element 200 rotates, the position of the contact with the transmission part 400 is changed, and the part in contact with the transmission part 400 is changed from the protruding part 220 to the body part 210, thereby achieving the unlocking of the locking part 500 and the release of the distribution auxiliary part.

[0077] In some embodiments of the present application, the driving element 300 is a linear driving mechanism for driving the release element 200 to move linearly, and the protruding part 220 is arranged along the axial direction of the body part 210 and is smoothly connected with the body part 210.

[0078] When the release element 200 moves linearly, the transmission part 400 switches the position between the protruding part 220 and the body part 210.

[0079] The linear driving mechanism is a linear motor, which is connected with the release element 200 and drives the release element 200 to move up and down along the axial direction.

[0080] When the locking part 500 is in the locking position, the protruding part 220 above the locking part 500 abuts against the transmission part 400, and when the releasing element 200 moves upward, the protruding part 220 is driven to move upward, so that the transmission part 400 contacts the body part 210, at this time, the locking part 500 is unlocked, and at the same time, when the releasing element 200 moves upward, it is also separated from the main laying part with which it is inserted and matched, so as to realize the separation from the main laying part.

[0106] The rotation of the release element 200 relative to the guide bracket 130 is realized by the first bearing 810 and the second bearing 820.

[0107] In some embodiments of the present application, the connecting bracket 140 is internally formed with:

[0108] A first cavity 144 with one side opening, which is in communication with the guide part 134;

[0109] And a second cavity 145, in which the locking part 500 is arranged.

[0110] The transmission part 400 extends through the guide part 134 into the first cavity 144 and extends from the first cavity 144 into the second cavity 145 and abuts against the locking part 500 in the second cavity 145.

[0111] In some embodiments of the present application, the release mechanism further comprises an elastic element 600 arranged in the first cavity 144 and the guide part 134, one end abutting against the wall of the first cavity 144 opposite to the opening, and the other end abutting against the abutting protrusion 420 of the transmission part 400.

[0112] When the transmission part 400 is in the locking position, the elastic element 600 is compressed between the abutting protrusion and the wall of the first cavity 144 and elastically deforms.

[0113] When the transmission part 400 is in the unlocking position, the transmission part 400 moves away from the locking part 500, the elastic element 600 recovers the deformation and applies a reverse elastic force to the transmission part 400, so that the transmission part 400 quickly separates from the locking part 500.

[0116] After the transmission member 400 releases the limiting of the locking part 500, the locking part 500 rotates under the action of the laying auxiliary part and is separated from the clamping part 143.

[0117] In some embodiments of the present application, a fixed bracket 160 is fixedly connected below the connecting bracket 140, and an arc-shaped clamping part 143 is formed on the fixed bracket 160 to clamp and limit the main laying part to avoid shaking of the main laying part during laying, thereby affecting the laying effect.

[0118] In some embodiments of the present application, a through hole 161 is symmetrically arranged on the fixed bracket 160.

[0120] When the release element 200 is in the locking position, one end of the carrying rope is connected to the fixed bracket 160, and the other end is hung on the locking part 500 through the lifting ring, and both ends are fixed, so that the carrying section formed between the two through holes 161 can carry the laying auxiliary part.

[0121] When the release element 200 is in the unlocking position, the lifting ring is separated from the locking part 500, at this time, the carrying rope passes out of the through hole 161 and slides downward, so that the carrying section between the two through holes 161 no longer carries the laying auxiliary part, and the force applied to the laying auxiliary part is eliminated, so that the laying auxiliary part is released and opened, and the laying is completed.
