The following detailed description of embodiments of the invention refers to the accompanying drawings.

First embodiment

Referring to fig. 1, the anchoring mechanism 100 of the present embodiment is applied to an engineering machine, and has both automatic anchoring and manual anchoring functions, so that the manual anchoring process is more labor-saving, and the manual anchoring is performed independently, thereby ensuring the smooth operation of the anchoring process.

The anchoring mechanism 100 of the present embodiment includes an anchoring frame 110, a linear actuator 120, a pulley 130, a movable member 140, a lifting rope 150, an anchor 160, a controller (not shown), a first detecting member 170, a second detecting member 180, and an auxiliary assembly 190.

The linear driving element 120 and the movable element 140 are respectively disposed on the anchor frame 110, and the movable element 140 can move relative to the anchor frame 110 under the action of an external force when manually anchored. The pulley 130 is rotatably provided at an output end of the linear actuator 120 and is capable of rotating relative to the linear actuator 120. The hoist rope 150 is spanned over the pulley 130, and one end of the hoist rope 150 is connected to the movable member 140 and the other end is connected to the anchor 160 to suspend the anchor 160 in a vertical plane in a natural state.

In the anchoring mechanism 100 of the present embodiment, when the anchor mechanism is automatically anchored, the movable element 140 is fixed relative to the anchor frame 110, and when the output end of the linear driving element 120 moves vertically downward, the pulley 130 is driven to move vertically downward, the lifting rope 150 generates a margin and moves to one side of the anchor 160 under the action of the gravity of the anchor 160, so as to realize the vertical downward movement until the anchor mechanism is inserted into the anchoring pit to complete the automatic anchoring, and in this process, the lifting rope 150 drives the pulley 130 to rotate counterclockwise. When the anchoring needs to be released, the output end of the linear driving member 120 moves vertically upwards to drive the pulley 130 to move vertically upwards and pull the lifting rope 150, so as to drive the anchoring member 160 to move vertically upwards until the anchoring is released from the anchoring pit, and the lifting rope 150 drives the pulley 130 to rotate clockwise in the process.

During manual anchoring, linear drive 120 remains stopped and an operator applies force to moveable member 140 to move moveable member 140 relative to anchor frame 110. When moveable member 140 moves in a first direction under the action of an external force and releases lifting rope 150, anchor 160 moves vertically downward until it is inserted into the anchoring pit to complete manual anchoring, and in the process, lifting rope 150 drives pulley 130 to rotate counterclockwise. When the movable member 140 moves in the second reverse direction under the action of the external force and pulls the lifting rope 150, the lifting rope 150 pulls the anchor 160 to move vertically upward until the anchor is withdrawn from the anchoring pit, and the manual release of the anchor is completed, in this process, the lifting rope 150 drives the pulley 130 to rotate clockwise.

It can be seen that, in the anchoring mechanism 100 provided in this embodiment, during the manual anchoring process, the pulley 130 plays a certain supporting role for the anchor 160, and is driven by the lifting rope 150 to rotate, so as to reduce the friction force. In addition, the linear driving element 120 does not work in the whole process of manual anchoring, and the output end of the linear driving element does not perform telescopic action, so that the contraction resistance of the output end of the linear driving element 120 does not need to be overcome in the process of manual anchoring, and the labor intensity is further reduced.

Referring to fig. 1 and 2, the anchor frame 110 is provided with a guide rail 111 extending in a vertical direction, and an output end of the linear driving member 120 is slidably engaged with the guide rail 111 to perform a positioning function in an automatic anchoring process. In this embodiment, the linear driving element 120 is an electric push rod, and the pulley 130 is disposed at an end of the electric push rod away from the body thereof through a rotating shaft. The lifting rope 150 is a steel wire rope, and in other embodiments, other flexible materials may be used.

The movable member 140 includes a rotation disc 141 and a rotation handle 143 connected to the rotation disc 141, the rotation disc 141 is rotatably disposed on the anchor frame 110, one end of the lifting rope 150 is wound on the rotation disc 141, and the rotation handle 143 is used for driving the rotation disc 141 to rotate under the action of an external force so as to retract and release the lifting rope 150.

In the process of automatic anchoring and automatic release of anchoring, the rotating handle 143 is relatively fixed to the anchoring frame 110 by a locking structure provided on the anchoring frame 110, that is, in the process of automatic anchoring and automatic release of anchoring, the winding and unwinding of the hanging rope 150 does not occur on the turntable 141. In the manual anchoring and manual anchoring releasing processes, the locking structure releases the locking of the rotating handle 143, and an operator applies acting force to the rotating handle 143, so that the rotating disc 141 is driven to rotate forwards or backwards, the lifting rope 150 is retracted, and the anchoring member 160 is lifted or lowered in the vertical direction.

Auxiliary assembly 190 is movably disposed on anchor frame 110, the other end of lifting rope 150 is connected to anchor 160 through auxiliary assembly 190, auxiliary assembly 190 is used to suspend anchor 160 in conjunction with lifting rope 150, i.e., auxiliary assembly 190 acts in conjunction with suspending anchor 160 to further reduce the labor intensity of manual anchoring and manual disarming processes.

Auxiliary component 190 includes pivot 191 and bending member 193, pivot 191 is rotationally disposed on anchor frame 110, bending member 193 includes first branch section 1931 and second branch section 1933, the one end of first branch section 1931 is connected and is connected anchor 160 jointly with the one end of second branch section 1933 at the contained angle, the one end that second branch section 1933 was kept away from to first branch section 1931 is connected with pivot 191, the one end that first branch section 1931 was kept away from to second branch section 1933 is connected with the other end of lifting rope 150.

In a natural state where the anchor 160 is in a suspended state, the first branch 1931 forms an angle with the vertical direction, that is, a resultant force of a supporting force of the rotating shaft 191 to the first branch 1931 and a pulling force of the lifting rope 150 to the second branch 1933 is balanced with a gravity of the anchor 160. Thus, during rotation of the stem 143 to retract the hoist rope 150, the operator overcomes the force which is only a component of the weight of the anchor 160.

In this embodiment, the number of the bending members 193 in the auxiliary assembly 190 is two, one end of the first branch 1931 of each of the two bending members 193, which is far away from the second branch 1933, is fixed on the rotating shaft 191, the second branch 1933 of one of the two bending members 193 is connected with the lifting rope 150, and the two bending members 193 are connected with the two anchors 160. Therefore, the auxiliary assembly 190 can simultaneously realize synchronous anchoring of the plurality of anchors 160, so that the energy consumption is reduced while the anchoring effect of the engineering machine is improved. In other embodiments, the number of the bending members 193 can be adjusted according to the actual application conditions.

The first detecting member 170 and the second detecting member 180 are respectively disposed on the anchor frame 110, and the controller is respectively connected to the linear driving member 120, the first detecting member 170, and the second detecting member 180. It can be understood that the controller may be a control host of the construction machine, or may be an independent control module in the mechanism.

The first detector 170 is used to send a first detection signal to the controller when the anchor 160 is aligned with the anchor pit in the vertical direction. When the controller receives the first detection signal, it determines that the anchoring can be performed at this time, and thus controls the linear driving member 120 to output vertically downward, so as to drive the pulley 130 to move vertically downward, i.e. enter into the automatic anchoring process. When the anchoring needs to be automatically released, the controller receives an input command from a user, and then controls the linear driving member 120 to drive the pulley 130 to move vertically upward.

The second detector 180 is used to send a second detection signal to the controller when the anchor 160 is moved to a preset position in the vertical direction. By presetting, when the anchor 160 is moved in the vertical direction to a preset position, complete anchoring is achieved. Therefore, when the controller receives the second detection signal, the controller controls the linear driving unit 120 to stop, and the automatic anchoring process is completed.

The anchoring mechanism 100 provided by the embodiment has the functions of automatic anchoring and manual anchoring, can realize automatic alignment through the first detection piece 170, and realizes anchoring in-place monitoring through the second detection piece 180, thereby improving the intelligence of the anchoring process of the engineering machinery. In addition, the auxiliary assembly 190, the movable element 140, the pulley 130 and the lifting rope 150 cooperate to greatly reduce the labor intensity in the manual anchoring process, and the manual anchoring process can be normally performed without overcoming the expansion resistance of the linear driving element 120 under the condition of failure of the linear driving element 120 and the like.

This anchoring mechanism 100 has the function of automatic anchoring and manual anchoring concurrently to can realize automatic alignment through first detection piece 170, realize the monitoring of anchoring in place through second detection piece 180, promote the intellectuality of engineering machine's anchoring process. In addition, the auxiliary assembly 190, the movable element 140, the pulley 130 and the lifting rope 150 cooperate to greatly reduce the labor intensity in the manual anchoring process, and the manual anchoring process can be normally performed without overcoming the expansion resistance of the linear driving element 120 under the condition of failure of the linear driving element 120 and the like.

Therefore, the crane provided by the embodiment saves more labor in the manual anchoring process, and ensures the smooth proceeding of the anchoring process because the manual anchoring is carried out independently.
