Abstract
The utility model discloses a self-lock chain stop device without the participation of brake force, which comprises an anchor chain channel and an anchor chain clamp, wherein the anchor chain channel is composed of a front slope, a middle channel and a back slope, two sides of the middle channel are respectively provided with anchor chain clamps, the anchor chain clamp is composed of a support arm and a hydraulic system while the hydraulic system is composed of a hydraulic cylinder and a movable arm, the fixed end of the support arm is hinged with the middle channel, the clamp end of the support arm is provided with a horizontal pin, the hydraulic cylinder is fixed on the middle channel, the movable arm of the hydraulic cylinder is connected with the support arm, and when the horizontal pins of the two clamp ends are contacted, the two support arms are cornered with the central line of 40-50 degrees. The self-lock chain stop device can accurately calculate the angle of the support arm to realize self-lock effect, and the angle of the support arm is designed according to the self-lock angle, the support arm can avoid horizontal support force that the hydraulic cylinder can avoid brake force to complete chain stop via self locking.
Description
Technical field
The utility model relates to the boats and ships accessory equipment field of berthing, and more particularly, relates to a kind of self-locking type chain stopper.
Background technology
Chain stopper is to be used for clamping anchor chain in the process of laying the mooring anchor chain, is fixed near the ship aft anchor cable entry bridge.Traditional chain stopper mostly is cutting knife type and pin formula chain stopper, needs the external world to provide bigger braking force just can finish the task of clamping anchor chain.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of self-locking type chain stopper that braking force participates in that need not is provided.
The utility model self-locking type chain stopper is achieved by following technical proposals, comprises anchor chain passage and anchor chain anchor clamps, and described anchor chain passage is connected to form by front end ramp, centre gangway and ramp, rear end; The centre gangway both sides are provided with the anchor chain anchor clamps respectively; Described anchor chain anchor clamps are made up of hold-down arm and hydraulic efficiency pressure system, and hydraulic efficiency pressure system is made up of hydraulic actuating cylinder and movable arm; Hold-down arm fixed end and centre gangway are hinged, and hold-down arm bare terminal end is provided with lateral pin, and hydraulic actuating cylinder is fixed in centre gangway, and movable arm is connected with hold-down arm, and two hold-down arms become 40 °-55 ° with line of centers when two bare terminal lateral pins contact.
The utility model is by meticulous calculating can reach the effect of self-locking to the angle of hold-down arm.According to the angle from locking angle design hold-down arm, hold-down arm can not need horizontal support power like this, and promptly hydraulic actuating cylinder can not participate in braking force, just can finish the only effect of chain by self-locking.The utility model is easy to operate, safe, reliable.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the anchor chain passage is connected to form by front end ramp 1, centre gangway 2 and ramp, rear end 3, and wherein the width of centre gangway is greater than front end ramp and ramp, rear end; The centre gangway both sides are provided with the anchor chain anchor clamps respectively; The anchor chain anchor clamps are made up of hold-down arm 4 and hydraulic efficiency pressure system, and hydraulic efficiency pressure system is made up of hydraulic actuating cylinder 5 and movable arm 6; Hold-down arm fixed end and centre gangway base are hinged, hold-down arm bare terminal 7 ends are provided with lateral pin, bare terminal 7 is used to step up the termination of anchor vertical chain ring, 7 places establish lateral pin at bare terminal, width between two arms of two lateral pins contact back is slightly larger than the section width of anchor chain, guarantees that the anchor vertical chain ring can be not bad by folder, and hydraulic actuating cylinder 5 is fixed in centre gangway, movable arm 6 is connected with hold-down arm 4, and two hold-down arms became 40 °-55 ° when two lateral pins contacted with line of centers.Bare terminal and lateral pin formed radian and the horizontal ring radian of anchor chain after closure adapt.
Owing to have clump weight on the anchor chain, the clump weight size is big (every about 8 tons), and it can be as anchor chain that works unsettled walking, and it is pasting deck plane, and the ship stern must be designed to the circular arc passage, so this channels designs is aslope.The about 1600mm of this gangway width, the bottom can be done in the arc-shaped.Utilize two rotating hold-down arms to withstand and brake at the horizontal ring of need glancing impact with anchor chain, hold-down arm bare terminal termination radian and anchor chain serobila (serobila is made of several interconnective vesica piscises) cross section adapts.The angle of hold-down arm is from the locking angle, this hold-down arm can not need horizontal support power, be that hydraulic actuating cylinder can not participate in braking force, but because the making of anchor chain and support arm head not necessarily can be symmetrical fully, the path of motion of anchor chain not unalterable, so fully by being difficult to accomplish from locking under the mode of operation, therefore, for the sake of security, install lateral pin additional in the termination of stepping up the anchor vertical chain ring, for expendable weight, this lateral pin adopts high strength steel.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineering staff make the technical solution of the utility model in this area various distortion and improvement all should belong to protection domain of the present utility model.
Claims (2)
1. a self-locking type chain stopper comprises anchor chain passage and anchor chain anchor clamps, it is characterized in that, described anchor chain passage is connected to form by front end ramp, centre gangway and ramp, rear end; The centre gangway both sides are provided with the anchor chain anchor clamps respectively; Described anchor chain anchor clamps are made up of hold-down arm and hydraulic efficiency pressure system, and hydraulic efficiency pressure system is made up of hydraulic actuating cylinder and movable arm; Hold-down arm fixed end and centre gangway are hinged, and hold-down arm bare terminal end is provided with lateral pin, and hydraulic actuating cylinder is fixed in centre gangway, and movable arm is connected with hold-down arm, and two hold-down arms become 40 °-55 ° with line of centers when two bare terminal lateral pins contact.
2. self-locking type chain stopper according to claim 1 is characterized in that, described bare terminal and lateral pin formed radian and the horizontal ring radian of anchor chain after closure adapt.
