Since the bucket 100 and the attachment bracket 200 are fixedly coupled, the following problems are easily caused:
(1) the working bucket 100 and the connecting frame 200 vibrate together along with the vibration of the arm support 300, and because the working bucket 100 is arranged at the tail end of the arm support 300, the amplitude of the working bucket 100 when the arm support 300 is completely unfolded is possibly very large, so that the life safety and comfort of operators in the working bucket 100 are seriously influenced;

In summary, in the prior art, when the boom 300 starts or stops and the movement speed or direction is changed, the boom 300 has a certain deflection, which causes a large amplitude vibration of the working bucket 100. Such vibration may cause discomfort or panic to the operator in the working bucket 100, and may cause the operator or the object in the working bucket 100 to shift the center of gravity and fall from the working bucket 100, or even cause the arm support 300 to resonate and affect the stability of the entire vehicle.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Referring to fig. 2 to 4, fig. 2 is a side view schematically illustrating a first embodiment of the work platform 1 according to the present invention, fig. 3 is an enlarged view schematically illustrating the link frame shown in fig. 2, and fig. 4 is a cross-sectional view schematically illustrating the link frame shown in fig. 2.
In the first embodiment, the work platform 1 includes the bucket 11, the attachment frame 12, and the cushion member 13. One end of the connecting frame 12 is fixed to an arm support (not shown), and the other end of the connecting frame 12 is used for connecting the working bucket 11. The buffer 13 is disposed between the working bucket 11 and the connecting frame 12, and the buffer 13 is used for buffering the movement of the working bucket 11 relative to the connecting frame 12 in at least one direction. Hereinafter, the buffer member 13 is exemplified to absorb the shock when the bucket 11 moves in the horizontal direction with respect to the connecting frame 12.
As shown in fig. 3, the buffer 13 includes a first fixing seat 131, a second fixing seat 132, a pin 133, a first elastic damping element 134, a second elastic damping element 135, and a shifting block 136. The first fixing seat 131 and the second fixing seat 132 are respectively fixed on the working bucket 11, and one end of the shifting block 136 is fixed on the connecting frame 12. Further, one end of the first elastic damping element 134 abuts against the first fixing seat 131, the other end abuts against the shifting block 136, one end of the second elastic damping element 135 abuts against the second fixing seat 132, and the other end also abuts against the shifting block 136. The first elastic damping element 134 and the second elastic damping element 135 are arranged in the same direction, and the elastic deformation directions of the first elastic damping element 134 and the second elastic damping element 135 are arranged in the horizontal direction.
Through holes are formed in corresponding positions of the first fixed seat 131, the second fixed seat 132, the first elastic damping element 134, the second elastic damping element 135 and the shifting block 136, the pin shaft 133 sequentially penetrates through the through holes of the first fixed seat 131, the first elastic damping element 134, the shifting block 136, the second elastic damping element 135 and the second fixed seat 132, and two ends of the pin shaft 133 are finally fixed to the first fixed seat 131 and the second fixed seat 132 respectively. Here, for example, when the first elastic damping element 134 and the second elastic damping element 135 both use cylindrical helical compression springs, the through hole of the first elastic damping element 134 or the second elastic damping element 135 can be understood as a radial through hole of the spring along the elastic deformation direction thereof. The pin 133 penetrates the first elastic damping element 134 and the second elastic damping element 135, so that the acting forces generated by the first elastic damping element 134 and the second elastic damping element 135 can be always kept in the same direction. Of course, the pin 133 may also be provided as two segments, wherein one segment sequentially passes through the respective through holes of the first fixing seat 131, the first elastic damping element 134, and the shifting block 136, and the other segment sequentially passes through the respective through holes of the second fixing seat 132, the second elastic damping element 135, and the shifting block 136. The forces generated by the first and second elastic damping elements 134, 135 can always be maintained in the same direction.
In the above embodiment, the first elastic damping element 134 and the second elastic damping element 135 are both cylindrical helical compression springs, and the first elastic damping element 134 and the second elastic damping element 135 are generally selected to be of the same type. As for the selection of the first elastic damping element 134 and the second elastic damping element 135, taking a cylindrical helical compression spring as an example, the stiffness coefficient and the initial pressure of the cylindrical helical compression spring can be specifically designed according to the different loads of the working bucket 11, so as to achieve the optimal damping effect. In addition, the selection of the first elastic damping element 134 and the second elastic damping element 135 is not limited to the compression spring, and a rubber material or a resin material having an elastic coefficient may be used without being limited thereto.
In the above embodiment, when designing the position of the dial 136, the dial 136 is usually disposed at the equilibrium position of the first elastic damping element 134 and the second elastic damping element 135, which can be understood as the position where the tension or the pressure of the first elastic damping element 134 and the second elastic damping element 135 to the two ends of the dial 136 are equal. The balance position includes a position where the tension or pressure of the first elastic damping element 134 and the second elastic damping element 135 to the two ends of the shifting block 136 is zero, and at this time, the two ends of the shifting block 136 are not stressed.
As shown in fig. 3, the connecting frame 12 at least includes two sliding parts 14, the two sliding parts 14 are respectively disposed outside two ends of the first fixing seat 131 and the second fixing seat 132, that is, one sliding part 14 is disposed on one side of the first fixing seat 131 far away from the second fixing seat 132; the other sliding member 14 is disposed on a side of the second fixing seat 132 away from the first fixing seat 131. The connecting frame 12 is also provided with at least through holes corresponding to the number of the sliding parts 14. Further, the slider 14 includes a slide groove 141, a roller 142, and a main shaft 143. The sliding groove 141 is disposed on the working bucket 11 and fixed to the working bucket 11, a track formed by the sliding groove 141 is parallel to the elastic deformation direction of the first elastic damping element 134, and the roller 142 is correspondingly disposed in the track formed by the sliding groove 141, wherein the track has a certain length to facilitate the roller 142 to roll within a certain range, and the main shaft 143 sequentially penetrates through corresponding through holes and the roller 142 on the connecting frame 12, and finally the roller 142 is fixed on the connecting frame 12. The main shaft 143 is equivalent to a driving shaft of the roller 142, and is used for driving the roller 142 to roll in the track formed by the sliding groove 141.
With continued reference to fig. 3, the connecting frame 12 further includes a first stop 144 and a second stop 145. The first stopper 144 and the second stopper 145 are respectively disposed at two ends of the sliding groove 141 and spaced from the sliding groove 141 by a distance, the distance is smaller than the diameter of the roller 142, when the bucket 11 and the connecting frame 12 move relatively in the horizontal direction, generally, the roller 142 is driven by the main shaft 143 to roll only in a small range without frequently colliding with the first stopper 144 or the second stopper 145, and if the rolling range of the roller 142 is large, the first stopper 144 and the second stopper 145 can effectively limit the movement of the roller 142, so that the roller cannot be separated from the track formed by the sliding groove 141.
Referring to fig. 5, fig. 5 is an enlarged cross-sectional view of the sliding member of the connecting frame shown in fig. 3 along the direction a-a. The cross section of the sliding groove 141 is of a step structure, the cross section of the roller 142 is of a middle expansion structure, and the expansion structure of the roller 142 is matched with the step structure of the sliding groove 141. The step structure of the sliding groove 141 and the expansion structure of the roller 142 cooperate with each other to properly limit the roller 142 within the track formed by the sliding groove 141, and because the roller 142 is actually connected with the connecting frame 12, the working bucket 11 and the connecting frame 12 can be relatively fixed together through the structural cooperation between the roller 142 and the sliding groove 141. With reference to fig. 4, the rollers 142 play an intermediate connection role and further achieve slidable connection of the connecting frame 12 to the working bucket 11, and at least a part of the structure of the rollers 142 is sandwiched between the sliding grooves 141, so that the rollers can also bear the weight of the working bucket 11 and enhance the mechanical strength of the connecting frame 12.
With reference to fig. 3 and 4, the principle of the relative movement between the bucket 11 and the connecting frame 12 in the horizontal direction is illustrated as follows:
when an operator enters the working bucket 11 to work, the working bucket is stimulated to vibrate, because the sliding connection is adopted between the working bucket 11 and the connecting frame 12, the component of the acting force applied to the working bucket 11 in the horizontal direction enables the working bucket 11 and the connecting frame 12 to generate relative motion, at this time, because the buffer part 13 is also adopted between the working bucket 11 and the connecting frame 12, when the working bucket 11 is subjected to the acting force which is leftward in the horizontal direction, the working bucket 11 will move leftward in the horizontal direction relative to the connecting frame 12, at this time, the shifting block 136 will compress the second elastic damping element 135, the energy generated by the acting force will be gradually absorbed by the second elastic damping element 135, so that the speed of the working bucket 11 moving leftward in the horizontal direction relative to the connecting frame 12 will be slower and the amplitude thereof will be reduced, when the acting force applied to the working bucket 11 disappears, the second elastic damping element 135 gradually releases the energy absorbed by the second elastic damping element, so that the working bucket 11 is restored to the balance position at a slower speed, and the shock absorption effect is achieved; when the working bucket 11 is subjected to a rightward acting force in the horizontal direction, that is, the working bucket 11 moves rightward in the horizontal direction relative to the connecting frame 12, the shifting block 136 compresses the first elastic damping element 134, and energy generated by the acting force is gradually absorbed by the first elastic damping element 134, so that the rightward moving speed of the working bucket 11 relative to the connecting frame 12 in the horizontal direction is relatively slow, the amplitude of the rightward moving speed is reduced, and when the acting force applied to the working bucket 11 disappears, the first elastic damping element 134 gradually releases the energy absorbed by the working bucket 134, so that the working bucket 11 returns to the equilibrium position at a relatively slow speed, thereby achieving a shock absorption effect.
Therefore, no matter the working bucket 11 does any relative motion in the horizontal direction relative to the connecting frame 12, the buffer member 13 can play a large damping effect, namely, the maximum amplitude and the maximum vibration speed can be reduced, so that the life safety of the operator can be greatly guaranteed, and the comfort of the working environment can be improved.
It should be noted that a plurality of buffering members 13 having the same structure as described above may also be disposed along the direction parallel to the elastic deformation direction of the first elastic damping element 134, so as to further improve the damping effect, and the description thereof is omitted.
In the above embodiment, the number of the connecting frames 12 is usually two, and the two connecting frames 12 are symmetrically disposed on two opposite sides of the working bucket 11, but of course, the two connecting frames 12 may be mounted on the top or the bottom of the working bucket 11. In addition, the installation direction of the buffer 13 can be set to be parallel to the horizontal direction or parallel to the vertical direction, when the installation direction is set to be parallel to the horizontal direction, the component of the acting force generated by the oscillation source in the horizontal direction has a damping effect, and when the installation direction is set to be parallel to the vertical direction, the component of the acting force generated by the oscillation source in the vertical direction has a damping effect. Moreover, the ends of the two connecting frames 12 protruding out of the working bucket 11 are provided with hinge seats (not shown), and the hinge seats are used for being connected and fixed with the arm support 2 in a hinge manner.
Fig. 6 is a schematic top enlarged view of another embodiment of the connecting frame in the working platform embodiment of the present invention, as shown in fig. 6. In one embodiment, one end of the dial 1360 may be fixed to the bucket 110, and the first fixing base 1310 and the second fixing base 1320 may be fixed to the connecting frame 120, and the first elastic damping element 1340 and the second elastic damping element 1350 may be arranged as described above and not described herein.
The embodiment of the invention also provides an overhead working truck.
As shown in fig. 7, a schematic side view of an embodiment of the aerial lift truck of the present invention. The aerial work vehicle comprises an arm support 1003 and a working platform 1000 according to any one of the above embodiments, wherein the working platform 1000 comprises a working bucket 1001 and a connecting frame 1002, and the arm support 1003 is fixedly connected with the working bucket 1001 through the connecting frame 1002.
In the embodiment of the invention, the buffer parts (combined with fig. 3) are additionally arranged on the working bucket 1001 and the connecting frame 1002, when the working bucket 1001 moves or displaces relative to the connecting frame 1002, part of energy caused by the movement or displacement is absorbed by the buffer parts, so that the vibration is reduced, the vibration amplitude and the vibration speed between the working bucket 1001 and the arm frame 1003 can be effectively reduced, and the safety and the comfort of an operator when the operator works on the working bucket 1001 are improved.
In conclusion, the working platform and the aerial work platform vehicle have the following advantages:
(1) the amplitude of the working bucket is small under the external stimulation of the same energy;
(2) the vibration speed of the working bucket is slower when the working bucket is in a vibration balance position under the external stimulation of the same energy;
(3) the amplitude of the working bucket and the maximum vibration speed of a balance position are reduced, so that the working bucket is more stable, and the safety and the comfort of the working bucket can be improved;
(4) the maximum vibration speed of the amplitude and the balance position of the working bucket is reduced, the fatigue degree of the working bucket and the arm support can be reduced, and the fatigue damage of the connecting frame is relieved.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
