The specific embodiment

Below by some embodiment the utility model is described in detail.But the multitude of different ways that the utility model can be defined by the claims and cover is implemented.This description taken in conjunction accompanying drawing carries out, and identical in the accompanying drawings parts are represented with identical label.

Below, introduce according to lifting appliance of the present utility model with reference to Fig. 1-5.

With reference to Fig. 1 and 2, comprise arm assembly 40, hook assembly 50 and column 80 according to lifting appliance 100 of the present utility model, the arm assembly is articulated in the top of column 80.As shown in Figure 1, hook assembly 50 is designed to be able to pivot between level attitude I and vertical position II with respect to arm assembly 40.

As illustrated in fig. 1 and 2, arm assembly 40 can be provided with stop part 44, and the Position Design of stop part 44 becomes backstop hook assembly 50 when hook assembly 50 is positioned at level attitude I.

In addition, in order to realize that hook assembly 50 can pivot with respect to arm assembly 40 between level attitude I and vertical position II, hook assembly 50 is provided with turnover bracket 51, turnover bracket 51 is articulated in arm assembly 40, and the line at the position that articulates and the center of the pulley 43 in arm assembly 40 heads is with respect to the angled α of perpendicular (as shown in Figure 2), preferably, angle [alpha] is 45 degree.When suspension hook rises to when contacting with the suspension hook turnover bracket, because the installation site and the angled α of telescopic boom head pulley center 43 lines of suspension hook turnover bracket 51, can draw by mechanical analysis, because suspension hook turnover bracket biasing, when continuing the pulling hoist rope, hook assembly 50 is past to sideway swivel with respect to the center of pulley 43 around the turnover bracket installation shaft with turnover bracket 51, when moving to stop motion when contacting, at this moment lock hoisting rope 70 and will make hook assembly 50 be in I place, flip horizontal position with baffle plate 44.Preferably, this moment, the medial surface of turnover bracket 51 contacted with the arm head end, reduce the stressed of turnover bracket installation shaft, and whole hook assembly was more steady in the process of moving.

Because the upset of this suspension hook plays lift by steel rope and drives, and is simple in structure and effective, fixes when suspension hook is in horizontal positioned I in addition, can guarantee bigger cargo space.

Be appreciated that and suitably carry out modification as required, for example, turnover bracket 51 of the present utility model can be installed with respect to the center vertical line mirror image of pulley 43, thereby hook assembly 50 inwardly can be turned over to level structure of the present utility model.

Outside upset as shown in Figure 1 realizes contacting with head end when turnover bracket 51 turns up to level attitude in the structure of horizontal location suspension hook.Be appreciated that if adopt the modification structures of above-mentioned mirror-image arrangement, contact with the end face of head end offside when then turning in the turnover bracket 51 to level attitude.

In addition, in order to prevent the damage of steel rope 70, steel rope 70 be arranged to from elevator assembly 10 extend and pass arm assembly 40 the inner space and via after pulley 43 in arm assembly 40 heads and the pulley 52 on the hook assembly in being fixed in arm assembly 40.Steel rope 70 is arranged in the arrangement space that whole loop wheel machine had both been saved in the arm the inside, can prevent steel rope scratch, wearing and tearing again, has improved the safety in utilization of steel rope.The profile of whole loop wheel machine is also more attractive in appearance in addition.

Further, the inner space of arm assembly 40 is provided with cylinder 45 at the end place near elevator assembly 10, and is provided with roller 46 at the end place near hook assembly 50.Thereby, steel rope 70 from elevator assembly 10 extend, via after pulley 43 in cylinder 45, roller 46, arm assembly 40 heads and the pulley 52 on the hook assembly in being fixed in arm assembly 40, help the easy motion of steel rope.

In addition, in order to save arrangement space, and avoid steel rope 70 and suspension hook and suspension hook turnover bracket 51 not to bump again and damage steel rope, the inboard welding of the head of arm assembly 40 is provided with adapter plate 41, and an end of steel rope 70 is fixed in adapter plate.And, to interfere in order to prevent steel rope and arm, the inboard of the head of arm assembly 40 can be welded and is provided with guide plate 42, and the pulley 52 of steel rope 70 from the hook assembly upwards is directed to adapter plate 41 and is fixed in adapter plate 41 in the end along guide plate 42.

The main body of arm assembly 40 can be set to a telescopic arms, and is flexible to regulate the length of arm assembly 40 by the driving realization of oil cylinder.

As shown in Figure 6, show a kind of according to the vehicle with lifting appliance of the present utility model.As shown in the figure, this vehicle has a cargo hold shelter at the rear portion.Preferably, lifting appliance is arranged at the tailstock place of vehicle.Lifting appliance has front leg strut and the rear support leg that is used to support the arm assembly, when lifting appliance is in running order, front leg strut is the H type, and foreleg comprises: a foreleg structure and an end are connected in the vertical oil cylinder of foreleg structure, thereby front leg strut is supported in map by vertical oil cylinder.When lifting appliance is in running order, rear support leg is the X type, back leg comprises: back leg structure and the cross cylinder and the vertical oil cylinder that are connected in back leg, wherein, the purpose of cross cylinder is to open with the formation X-shaped for rear support leg extends from the vehicle both sides, and the effect of vertical oil cylinder is for rear support leg is supported on the ground.

In sum, according to lifting appliance of the present utility model and the vehicle with this lifting appliance, it has following characteristics: 1. lifting appliance is arranged at the rear of vehicle, and hoist rope is hidden in the arm the inside, save the space, make that structure is compact more, profile is more attractive in appearance.The steel wire loop assembly is arranged in arm head inside, has avoided the damage of steel rope.The arm head design has the suspension hook switching mechanism, and purpose is to make car load suspension hook under motoring condition be in horizontality, avoids bumping with shelter, and can reduce the height of car load.The front leg strut of lifting appliance is the H type, is made of vertical oil cylinder, and rear support leg is the X type, thereby strengthens departure angle, is formed, thereby can more effectively be supported device for hoisting by leg structure, cross cylinder, vertical oil cylinder.

Therefore, although the utility model is illustrated with reference to accompanying drawing and preferred embodiment, obviously, for a person skilled in the art, under the prerequisite that does not deviate from spirit and scope of the present utility model, can make various changes and variation to the utility model.Various change of the present utility model, the content that changes by appending claims and equivalent thereof contain.
