Detailed Description

It should be noted that, in the case of conflict, the embodiments and features of the embodiments in the present application may be combined with each other, and the present invention will be described in detail with reference to the accompanying drawings and the embodiments.

In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships, without particular description, based on the orientations or positional relationships shown in the drawings, merely for convenience of description and simplification of the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 5, the present embodiment provides a barrier lock apparatus including: the lock rod mechanism 3 is arranged on the left connecting plate 1, the lock cylinder mechanism 4 is arranged on the right connecting plate 2, the left connecting plate 1 is arranged on the guardrail door, and the right connecting plate 2 is arranged on the guardrail; the lock cylinder mechanism 4 comprises a key 9, a lock pressure block 10, a reinforcing sleeve pressure plate 11, a locking pin 12, a return spring 13, a reinforcing sleeve 14, an ejector pin 15, an ejector pin spring 16, a lock body cover plate 17 and a lock body 18. When personnel need operate jacking equipment, take out key 9 from jacking equipment and insert lock core mechanism and rotate key 9 and open the guardrail lock, the guardrail lock is automatic to be opened, and personnel can get into jacking equipment through the guardrail. After personnel get into jacking equipment, the key is inserted in lock core 4 of guardrail lock and can't be extracted this moment, if need operate jacking equipment operation, at first need push into lock core mechanism 4 with push rod 7, rotatory key is with the guardrail lock locking, and the guardrail door is closed this moment, just can extract the key, and personnel can operate jacking equipment operation.

The beneficial effect of this embodiment is that foretell interlocking state has guaranteed that lifting equipment is unable the operation under the lifting equipment is in the open mode at the guardrail door namely interlock is in the unblock state, has consequently avoided because personnel forget etc. factor and lead to the guardrail not close and lifting equipment is in the risk that can move, has guaranteed personnel's security.

Preferably, the locking pin 12 is hemispherical at its upper end and cylindrical at its lower end. The guardrail lock is opened and closed by means of the rotation of the key 9, and the key 9 can easily press down the locking pin 12 by means of friction because the upper end of the locking pin 12 is hemispherical. The cylindrical shape of locking round pin 12 lower extreme can block into the inslot of push rod 7, prevents push rod 7 axial motion, reachs the effect of locking, and locking round pin 12 lower extreme is cylindrical simultaneously, can restrict the axial motion of push rod 7 completely, has strengthened the intensity of guardrail lock, avoids causing the guardrail lock to open because of external force.

Preferably, one end of the return spring 13 is pressed against the hemispherical surface at the upper end of the locking pin 12, and the other end of the return spring is pressed against the upper surface of the reinforcing sleeve pressing plate 11. When the key 9 is rotated to press down the locking pin 12, the return spring 13 is also in a compressed state, and when the key 9 is rotated again, the return spring 13 pushes the locking pin 12 upwards, the lower end of the locking pin 12 is separated from the groove of the push rod 7 in a cylindrical shape, meanwhile, the ejector pin 15 is pushed back to the original position by the ejector pin spring 16, and the guardrail lock is opened.

Preferably, a stepped hole is formed in one side of the reinforcing sleeve pressing plate 11, and the upper end of the reinforcing sleeve 14 penetrates into the stepped hole in the reinforcing sleeve pressing plate 11. When the guardrail lock device is subjected to external force, the locking pin 12 can firstly impact the reinforcing sleeve 14, so that the strength of the guardrail lock is improved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
