The specific embodiment
First core of the present utility model is for providing a kind of jib, and this jib structure is simple, compact, and it is little to take up room.Second core of the present utility model is for providing a kind of aloft work vehicle that comprises above-mentioned jib.
In order to make those skilled in the art understand the technical solution of the utility model better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 2 and Fig. 3, the perspective view of the connecting device in the jib that the mounting structure scheme drawing of the jib that Fig. 2 provides for the utility model, Fig. 3 provide for the utility model.
In a kind of specific embodiment, the jib that the utility model provides comprises arm 1, No. two arms 2 and is used to support the bearing set 3 of No. two arms 2; One end of an arm 1 is connected on the vehicle frame usually, and its other end and No. two arms 2 are hinged; No. two arms 2 are articulated in the sidepiece of an arm 1; Bearing set 3 is suspended in the side of an arm 1, and it is provided with the carrying surface that is used to support No. two arms 2.
The side away from vertical section on the carrying surface can be provided with block, to prevent the landing from the carrying surface of No. two arms 2.
The jib that the utility model provides is suspended in bearing set 3 on the side of an arm 1, and this bearing set 3 is provided with the carrying surface of No. two arms 2 of supporting.
Because No. two arms 2 are articulated in the sidepiece of an arm 1, when off working state, No. two arms 2 are that fulcrum lands downwards with the hinge-point, finally are pressed on the carrying surface of bearing set 3.
Bearing set 3 is arranged on the side of an arm 1, because No. two arms 2 of distance are nearer, only need make bearing set 3 suspend a segment distance from the side of an arm 1, can realize supporting the function of No. two arms 2, the structure that this has simplified bearing set 3 makes the structure of whole jib become compact more simultaneously; And bearing set 3 is arranged on the side of an arm 1, this bearing set 3 does not take the space on vehicle frame surface, thereby can save the space on vehicle frame surface, and then whole jib occupation space is reduced.
Can be on the side of an arm 1 and on the bearing set 3 through hole match being set respectively, by tie bolt 4 is plugged in the above-mentioned through hole, realize being connected of bearing set 3 and an arm 1; Also can on the side of an arm 1 and bearing set 3 one among both, through hole be set, on another person screw rod be set, realize being connected of bearing set 3 and an arm 1 by screwing nut.Two row's tie bolts 4 can be set.It is simple in structure that tie bolt 4 is set, and connects firm.
The spacing of each adjacent tie bolt 4 can be set to equate, like this in fitting process, can select the concrete connecting portion of arm 1 and bearing set 3 as required, to realize the adjusting of relative position between the two.Because the distribution straight line of tie bolt 4 can when an arm 1 is in horizontal positioned, can realize that the upper-lower position of bearing set 3 is regulated perpendicular to the axis of an arm 1.
Please further with reference to figure 4, Fig. 4 is the structural representation of another angle of the connecting device in the jib shown in Figure 3.
Can be provided with on the bearing set 3 and regulate bolt 31, the axis of regulating bolt 31 can be parallel to the axis of an arm 1; Can be provided with on No. two arms 2 and regulate the baffle plate 21 that bolt 31 matches, baffle plate 21 can be perpendicular to the axis of No. two arms 2.
As herein describedly vertically comprise approximately perpendicular situation.
When No. two arms 2 are pressed on the bearing set 3, adjusting bolt 31 can be transferred to and touch the position of keeping out plate 21, under vehicle running state, can prevent that No. two arms 2 from end float misalignments taking place like this.
Can be provided with buffering stand 32 on the carrying surface of bearing set 3, this buffering stand 32 can be for having certain thickness rectangular body, the block that limits No. two arms 2 can be set on it, this block can be parallel to the axis of No. two arms 2, be arranged on the two ends of rectangular body, to prevent that No. two arms 2 are from cushioning landing on the support 32.This block can be wholely set with buffering stand 32, also can the split setting, then by connection modes such as bolts, be connected on the buffering stand 32.This buffering stand 32 can be made by the rubber-like material, also can be formed by stacking by rigid material.When No. two arms 2 landed in carrying surface, this buffering stand 32 can reduce the impulsive force of 2 pairs of bearing sets 3 of No. two arms, and then can play buffer action.
Can between the carrying surface of buffering stand 32 and bearing set 3, spring 33 be set.When buffering stand 32 is set to rectangular body, can four springs be set at four jiaos of places of rectangular body, the size of the impulsive force the when number of spring can land according to No. two arms 2 is adjusted.Spring is set realizes buffer action better No. two arms 2.
The utility model also provides a kind of aloft work vehicle, comprise vehicle body and with vehicle body bonded assembly jib, this jib is above-described jib.Because this aloft work vehicle comprises above-described jib, its also corresponding technique effect with the above jib, the technical characterictic of these other parts of aloft work vehicle sees also prior art, does not repeat them here.
This aloft work vehicle can be elevating fire truck.
This aloft work vehicle can also be aerial platform.
Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
