During middle hoister in large tonnage auxiliary suspension status, auxiliary generally adopts three-point fix, is front frame location, medium-height trestle location, after poppet location respectively.Three locating points will realize the full degree of freedom constraint of auxiliary, ensure reliable, stable being fixed on crane arm of auxiliary.
Front frame is near crane arm head side, and be mainly used in realizing auxiliary and rotate, front frame need provide auxiliary first half section a supporting plane in addition, guarantees to rotate to pivot and auxiliary transportation steady.The main bearing support that medium-height trestle supports as auxiliary, the auxiliary center of gravity posterior segment of general design, Main Function be at auxiliary in front frame rotary course, provide one support and climbing platform, coordinate with front frame auxiliary to reclaim and pulled out, and final fixing auxiliary and hoisting crane side.After poppet is arranged on auxiliary rear end, guarantees to coordinate with medium-height trestle when Main Function is two joint auxiliary independent suspension, realizes the full degree of freedom constraint of two joint auxiliarys, during motoring condition, for reinforcing auxiliary constraint.When auxiliary tail end is too near crane arm afterbody, cannot realize by fixing the mode realizing two joint auxiliarys fixing, two joint auxiliary abutment joints, must leave joint one segment distance to arrange after poppet, after poppet version in the past cannot meet user demand.
First this after poppet adopts bolt inhibiting device, utilizes the bolt be fixed on two joint auxiliarys to hold out against after poppet, limits when auxiliary reclaims and exceedes appointment rigging position, avoids auxiliary to reclaim and impacts.Secondly for guaranteeing that after poppet support comprehensively can save auxiliary bearing surface with two and contact, this support Design become can local rotated versions, utilize bolt to control the anglec of rotation, and then realize support roller and two and save auxiliary bearing surface full face contact, two hidden danger saving the variation of auxiliary self hanging position when avoiding independent suspension.Finally in rotatable support, installed axis pin base, this axis pin base utilizes a set of assembling bolt can realize self rotatable adjustment equally, and retrain for realizing the axle of wearing of vertical direction between two joint auxiliarys and after poppet, reliability is higher.
Crane arm: for hoisting heavy, can realize luffing by oil cylinder and stretch, one be formed by two pieces of bent plate butt welding, and cross section is the structure of similar rectangle.During off working state, be the level of state along vehicle body direction placement.
Auxiliary: for increasing the sling height of hoisting crane and the arm support framing member of amplitude, be suspended on crane arm side during off working state, needs during work to rotate pull-out around any and dock with crane arm to use.
Support: be fixedly mounted on crane arm side (being generally right side), play the degree of freedom zero constraint between auxiliary and crane arm and supporting role during auxiliary suspension status, play auxiliary assembling effect when auxiliary is in running order.

Auxiliary is divided into two kinds of mounting forms: one is that two joint auxiliary folded states are articulated in side simultaneously, and when another kind is a joint auxiliary pull-out operation, two joint auxiliarys are suspended on separately hoisting crane side.
Be illustrated in fig. 1 shown below, be crane subsidiary arm suspension status, suspension gear is generally made up of three supports, and wherein the effect of front frame has two: one to be for supporting, retraining a joint auxiliary; Another effect is the centre of gration serving as auxiliary rotation first, realizes major and minor arm arm head axis hole docking (the O position see Fig. 2).
The effect of medium-height trestle mainly contains two: the first, during suspension status, for supporting and constraint one, two joint auxiliary, guarantees stability when one or two joint auxiliarys hang; The second, when using auxiliary recovery auxiliary, open on two joint brackets of folded state, two joint support platforms are provided to assist auxiliary and front frame to assemble, need to use auxiliary, during pull-out auxiliary, provide support smooth the docking (being illustrated in fig. 2 shown below) that platform assists auxiliary and crane arm O position axis hole.
After poppet is used for fixing auxiliary afterbody, generally has two kinds of fixed forms: one is by fixing (see Fig. 3 after poppet I) with two joints saving arm afterbody, and two is in the position near two joint arm afterbody certain distances, wears axle fix with support cooperation.The Main Function of after poppet is the reliability for increasing integral hanging, and guarantees that two joint auxiliary independent suspensions are on crane arm
Time stability and regain one joint auxiliary time failure-free docking property.
After poppet, according to position during fixing auxiliary, is divided into two kinds of fixed forms: one is fix at two joint auxiliary afterbodys, and shown in See Figure 4, two is fix, shown in See Figure 5 in the position near two joint auxiliary afterbody certain distances.
Mount the car hosit mounting mode that state I is relatively little tonnage in Fig. 4, save auxiliary arm tail joint by support and two and wear axle and retrain to realize auxiliary and fix.When hoisting crane tonnage is relatively large, after auxiliary weight increases relatively, as shown in Figure 4, because after poppet only constrains two joint auxiliary afterbody sides, therefore the fixed position of two joint auxiliarys can be caused to drop because of self gravitation after pull-out one joint auxiliary, and then when causing a joint auxiliary to reclaim with two save the hinged difficulty of auxiliary, even cannot realizing one, two, to save auxiliarys hinged.Mounting state shown in Fig. 5 then there will not be above-mentioned phenomenon, but the mounting mode shown in Fig. 5 can be steeved because of crane arm, causes two joint auxiliarys in crane arm direction generation shift in position to a certain degree.
Because two joint auxiliarys are certainly as box, and then fixed pin shaft that is rear in causing, support can only insert in the horizontal direction.The bearing pin of horizontal direction cannot retrain the degree of freedom of two joint auxiliary horizontal directions, therefore when two joint auxiliarys are in independent mounting state, two joint auxiliarys can occur locally mobile relative to after poppet along wearing direction of principal axis, and then are difficult to when causing a joint auxiliary to reclaim complete hinged fixing with two joint auxiliarys.In addition due to after poppet and two, to save gap between auxiliary relatively little, and inhibiting device is difficult to arrange, arranges even if complete space, clashes into the distortion also easily causing two joint auxiliary cylindrical shells for a long time.During current recovery auxiliary, be all manually control auxiliary to reclaim position, two joint auxiliary Chang Huiyu after poppets collide in this process.
