Description

[01] The present invention relates to an outrigger assembly comprising an outrigger frame and an outrigger beam movable in a horizontal extension direction relative to the outrigger frame between a retracted position and an extended position. The outrigger beam is positioned inside the outrigger frame in the retracted position and extends from the outrigger frame in the extended position. The outrigger beams have proximal and distal ends relative to the outrigger frame in an extended position of the outrigger beams. The outrigger assembly further includes an outrigger support coupled to the distal end of the outrigger beam for supporting the outrigger assembly at the support position of the outrigger support on the support surface in the extended position of the outrigger beam. The invention further relates to any vehicle, such as a mobile crane, provided with such an outrigger assembly having horizontally extendable outrigger beams.

[02] Mobile cranes and other vehicles having outrigger assemblies are generally known. Outrigger beams extend from the outrigger frame and vehicle, and the outrigger supports are lowered onto the ground where heavy loads are handled. The extended outrigger beams give the mobile crane greater stability and can handle higher loads as the width of the extended outrigger assembly is increased. The width of the extended outrigger assembly is determined by the length of the outrigger beam, which is limited by the width of the vehicle in which the outrigger beam is accommodated in its stowed position. Current vehicles with outrigger assemblies, particularly mobile cranes, have reached a limit on the maximum width of the extended outrigger assembly that can be reached. However, further increases in width will increase stability or the maximum load or load moment (load at a particular radius) that can be accommodated.

detailed description

[26] Figure 2 shows the mobile crane in position for operating the crane portion; The outrigger beams 200 of the outrigger assembly 10 extend from an outrigger frame 100 that is part of the mobile crane, and the outrigger supports 300 are placed in support positions on a support surface S, which is the road surface. can be any other generally horizontal plane. The outrigger supports in the extended position provide stability to the crane for handling heavy loads. FIG. 3 shows outrigger assembly 10 in greater detail according to the present invention with outrigger beam 200 in an extended position and outrigger support 300 in a support position supporting the outrigger beam on support surface S. As shown in FIG.

[27] Figures 4A-4D illustrate the transition from the retracted position P4 of Figure 4A, where the outrigger beams are positioned within the outrigger frame 100, to the extended position P1 of Figure 4D, where the outrigger beams are fully extended from the outrigger frame. , shows the four stages for providing the outrigger beam 200. FIG. 4B and 4C show the intermediate position of outrigger beam 200 as it moves along horizontal extension direction E relative to outrigger frame 100 to the extended position of FIG. 4D. The outrigger beams are movable by operating outrigger beam actuators 150,160.

[28] The outrigger frame 100 includes a movable cam 400 that is moved into a recess 211 provided in the upper surface of the outrigger beam in the fully extended position P1 shown in Figure 4D. The cam is rotatable about axis of rotation 410 and can be rotated into and out of recess 211 by cam actuator 450 in the illustrated embodiment, but can be moved into and out of recess in any other suitable manner. can also Cam actuator 450 is a pneumatically controlled actuation cylinder in the illustrated embodiment, but may be any other suitable actuator such as, for example, a hydraulic, manually, or electrically controlled actuation cylinder. On its bottom side, the outrigger beam is connected to the outrigger frame via slider elements 500 . A slider element, in the form of a slider rod in the illustrated embodiment, has first and second ends 501 , 502 . The first end 501 of the slider element is retained in the slot by the projection of the slider element extending into the elongated slot 250 in the bottom region of the outrigger beam 200 . A protrusion at the first end 501 of the slider element can slide along the slot between the first slot end 251 and the second slot end 252 . FIG. 4D, in the extended position of the outrigger beams, shows the protrusions on the slider element first end 501 cooperating with the first slot end 251 . A protrusion at the second end 502 of the slider element 500 cooperates with a first stop 111 at the bottom region of the outrigger frame 100 .

[29] The outrigger support 300 is in the support position SP in the extended position P1 of the outrigger beam in FIG. 4D. In the support position, the outrigger support footplate 310 is lowered onto the support surface S by operating the outrigger support actuation cylinder 320 . 4A-4C show the foot plate 310 of the outrigger support 300 in the raised position, which moves the outrigger beams in and out between the retracted position P4 of FIG. 4A and the extended position P1 of FIG. 4D. enable The outrigger support 300 is connected to the distal end 202 of the outrigger beam 200 while the outrigger beam is connected to the outrigger frame 100 at its proximal end 201 . A proximal end 201 and a distal end 202 of the outrigger beams are defined with respect to the outrigger frame. In the extended position, distal end 202 of outrigger beam 200 is positioned away from the outrigger frame, while proximal end 201 is positioned closer to the outrigger frame. Proximal and distal are each intended to denote an end zone and not an extreme end.

[30] In the extended position of the outrigger beam 200 of FIG. Supports the weight of a vehicle, such as some mobile cranes, and its loads and load moments. The outrigger support 300 exerts a first vertical force Fv1 acting upwardly at a first location L1 on the distal end 202 of the outrigger beam. The outrigger frame is supported on the outrigger beams via cams 400 inserted in the first recesses 211, the cams 400 exerting a second normal force downward at a second position L2 on the outrigger beams. Causes Fv2. The second location L2 is separated from the first location L1 toward the proximal end of the outrigger beam by a first horizontal distance Dh1. In the illustrated embodiment, the second position L2 is near the extreme end of the proximal end of the outrigger beam. In practice, the force may be distributed over zones, but can be considered acting on a single location on the frame, and is so shown in the figures. First and second vertical forces Fv1, Fv2 separated by a first horizontal distance Dh1 cause a first torque to act on the outrigger beam.

[31] The first torque is balanced by a second torque determined by the interaction of the outrigger frame and the outrigger beams via cam 400 and slider element 500 . A cam 400 coupled to the outrigger frame 100 and inserted into the first recess 211 induces a first horizontal force Fh1 acting outwardly at a third position L3 on the outrigger beam. In practice, the second and third positions are the same or nearly the same, because both the second vertical force Fv2 and the first horizontal force Fh1 are caused by cams 400 acting on the outrigger beams. . In general, the second and third positions L2, L3 need not be the same. The slider element 500 is inserted into the slot 250 and by virtue of the protrusion at its first end 501 cooperating with the first slot end 251 , the outrigger beam is positioned next to the first slot end 251 . It causes a second horizontal force Fh2 acting inward at the upper fourth position L4. A horizontal force is defined as outward or inward with respect to the outrigger frame, with an outward direction directed away from the outrigger frame and an inward direction directed toward the inside of the outrigger frame. A second horizontal force Fh2 can be exerted by the slider element because its second end 502 cooperates with the first stop 111 on the outrigger frame 100 . The fourth location L4 is spaced downwardly from the third location L3 by a first vertical distance Dv1. First and second horizontal forces Fh1, Fh2 separated by a first vertical distance Dv1 cause a second torque to act on the outrigger beam. The slider element 500 also induces a slight downward vertical force component acting on the outrigger beams due to the practical implementation of the illustrated embodiment. The same may be the case when applying the first horizontal force. However, these forces are substantially horizontal. A substantially horizontal force component acts to induce a second torque.

[32] Figure 1 shows a prior art outrigger assembly with an outrigger beam 200 in an extended position from an outrigger frame 100 and an outrigger support 300 in a support position on a support surface. In prior art outrigger assemblies, a torque caused by normal forces FvA and FvB acting on positions LA and LB, respectively, balances another torque caused by vertical forces FvC and FvD acting on positions LB and LC, respectively. Positions La and LB are separated by a horizontal distance DhA, and positions LB and LC are separated by a horizontal distance DhB. The torque due to the vertical forces FvA, FvB and the horizontal distance DhA is comparable to the first torque due to the first and second vertical forces Fv1, Fv2 and the first horizontal distance Dh1 in the outrigger assembly according to the invention, and the vertical force FvC , FvD and the horizontal distance DhB are replaced by first and second horizontal forces Fh1, Fh2 and a second torque due to the first vertical distance Dv1. Prior art outrigger assemblies require a significant length of the outrigger beam to remain inserted inside the outrigger frame to allow torque due to vertical forces FvC and FvD and horizontal distance DhB; This is not required by the outrigger assembly according to the present invention.

[33] FIGS. 5A-5C show from the retracted position P4 of FIG. 5A, where the outrigger beams are positioned within the outrigger frame 100, to the first half of FIG. 5C, where the outrigger beams partially extend from the outrigger frame. Three stages are shown for providing the outrigger beam 200 to the extended position P2. A first semi-extended position P2 is between the retracted position P4 and the extended position P1 of FIG. 4D. 5B shows the intermediate position of outrigger beam 200 as it moves along horizontal extension direction E relative to outrigger frame 100 to the first semi-extended position of FIG. 5C.

[34] The outrigger support 300 is in a support position SP in a first semi-extended position P2 shown in FIG. The rotatable cam is further rotated such that it is inserted into a second recess 212 provided in the upper surface of the outrigger beam 200 in the first semi-extended position. On its bottom side, the outrigger beam is connected to the outrigger frame, also via slider elements 500 . The first end 501 of the slider element is retained in the slot by the projection of the slider element extending into the elongated slot 250 in the bottom region of the outrigger beam 200 . FIG. 5C of the first semi-extended position of the outrigger beam shows that the protrusions on the slider element first end 501 cooperate with the first slot end 251 . A projection at the second end 502 of the slider element 500 cooperates with a second stop 112 at the bottom region of the outrigger frame 100 .

[35] In the first half-extended position of the outrigger beams of FIG. 5C, the outrigger supports 300 support the outrigger beams and the outrigger frame. The outrigger support 300 exerts a third vertical force Fv3 acting upwardly at a first position L1 on the distal end 202 of the outrigger beam. The outrigger frame is supported on the outrigger beams via cams 400, which are also now inserted in the second recesses 212, the cams 400 downwardly extending at a fifth position L5 on the outrigger beams. causing a fourth vertical force Fv4 to act. A fifth position L5 is a second horizontal distance Dh2 from the first position L1 toward the proximal end 201 of the outrigger beam. The second horizontal distance Dh2 is shorter than the first horizontal distance Dh1, and the fifth position L5 is at a horizontal position between the first position L1 and the second position L2. Third and fourth vertical forces Fv3, Fv4 separated by a second horizontal distance Dh2 cause a third torque to act on the outrigger beams.

[36] The third torque balances the fourth torque, which is also determined by the interaction of the outrigger frame and the outrigger beams via cams 400 and slider elements 500 . A cam 400 connected to the outrigger frame 100 and inserted into the second recess 212 induces a third horizontal force Fh3 acting outwardly at a sixth position L6 on the outrigger beam. The fifth and sixth positions L5, L6 are the same or substantially the same because both the fourth vertical force Fv4 and the third horizontal force Fh3 are caused by cams 400 acting on the outrigger beams. In general, the fifth and sixth positions L5, L6 need not be the same. The slider element 500 is inserted into the slot 250 and by virtue of the protrusion at its first end 501 cooperating with the first slot end 251 , the outrigger beam is positioned next to the first slot end 251 . It causes a fourth horizontal force Fh4 acting inwardly at the upper seventh position L7. In practice, the fourth and seventh positions L4, L7 are the same position in the illustrated embodiment. A fourth horizontal force Fh4 can be induced by the slider element because its second end 502 cooperates with the second stop 112 on the outrigger frame 100 . The seventh position L7 is separated from the sixth position L6 in a downward direction by a second vertical distance Dv2. The first and second vertical distances Dv1, Dv2 are the same in the illustrated embodiment. Third and fourth horizontal forces Fh3, Fh4 separated by a second vertical distance Dv2 cause a fourth torque to act on the outrigger beams. Again, there may be a vertical force component in addition to the horizontal force as described for the extended position P1. It is essentially a horizontal force component that acts to induce a fourth torque.

[37] FIGS. 6A and 6B show from the retracted position P4 of FIG. 6A, where the outrigger beams are positioned in the outrigger frame 100, to the second half of FIG. Two stages are shown for providing the outrigger beam 200 to the extended position P3. Intermediate positions are not shown. In the second semi-extended position of FIG. 6B, the outrigger beams 200 are not extended as far from the outrigger frame 100 as in the first semi-extended position of FIG. 5C.

[38] The outrigger support 300 is in a support position SP in a second semi-extended position P3 shown in FIG. The outrigger support 300 exerts a fifth vertical force Fv5 acting upwardly at a first position L1 on the distal end 202 of the outrigger beam. The outrigger frame, in the second semi-extended position P3, is directly supported on the outrigger beam at an eighth position L8 and exerts a sixth vertical force Fv6 acting downwardly at an eighth position L8 on the outrigger beam. An eighth position L8 is spaced from the first position L1 toward the proximal end 201 of the outrigger beam by a third horizontal distance Dh3. The third horizontal distance Dh3 is shorter than the first horizontal distance Dh1, and the eighth position L8 is at a horizontal position between the first position L1 and the second position L2. In the illustrated embodiment, the third horizontal distance Dh3 is also shorter than the second horizontal distance Dh2, and the eighth position L8 is located at a horizontal position between the first position L1 and the fifth position L5. be. Fifth and sixth vertical forces Fv5, Fv6 separated by a third horizontal distance Dh3 cause a fifth torque to act on the outrigger beams.

[39] The fifth torque balances the sixth torque determined by the direct interaction of the outrigger frame and the outrigger beam. The outrigger frame exerts a seventh vertical force Fv7 acting downward at a ninth position L9 on the outrigger beam. Due to the limited contact area between the upper side of the outrigger beam and the outrigger frame, the eighth and ninth positions L8, L9 are actually the same or nearly the same in the illustrated embodiment. Generally, the eighth and ninth positions L8, L9 need not be the same. Additionally, the outrigger frame exerts an eighth vertical force Fv8 acting upwardly at a tenth position L10 on the outrigger beam. The tenth position L10 is separated from the eighth position L8 in a direction toward the proximal end 201 of the outrigger beam by a fourth horizontal distance Dh4. Seventh and eighth vertical forces Fv7, Fv8 separated by a fourth horizontal distance Dh4 cause a sixth torque to act on the outrigger beams. Since the sixth and seventh normal forces Fv6, Fv7 act on (approximately) the same locations L8, L9, they sum to a single normal force Fv6+Fv7. However, there are still two torques acting on the outrigger beams to balance each other.

[40] The outrigger assembly includes first and second outrigger beam actuators 150 operable to move the outrigger beam 200 and the outrigger frame 100 relative to each other and to move the slider element 500 and the outrigger beam 200 relative to each other; 160. First outrigger beam actuator 150 operates to move outrigger beam 200 along with second outrigger beam actuator 160 and slider element 500 relative to outrigger frame 100 . Second actuator 160 operates to move outrigger beam 200 relative to slider element 500 and outrigger frame 100 . In the illustrated embodiment, the first outrigger beam actuator 150 includes a first cylinder portion 151 and a first piston portion 152 movable relative to the first cylinder portion and coupled to the outrigger frame 100 . and a second outrigger beam actuator 160 is movable relative to the second cylinder portion 161 and coupled to the outrigger beam 200 A second outrigger actuation cylinder having a second piston portion 162 is provided. The first and second cylinder parts 151, 161 and the first end of the slider element are fixedly connected to each other.

[41] In the stowed position P4 shown in FIGS. 4A, 5A and 6A, the slider element 500 is in the first slider element position SE1 where the second end 502 of the slider element is held by the outrigger beam 200. be. In first slider element position SE 1 , slider element first end 501 is at second slot end 252 of slot 250 , but slider element second end 502 is at outrigger beam 200 . It is retained within the slider element recess 260 at the extreme end of the proximal end. As shown in FIG. 6B, to reach the second semi-extended position P3, the first outrigger beam actuator 150 is moved to the first position while the slider element 500 is maintained at the first slider element position SE1. One piston portion 152 is operated to extend from the first cylinder portion 151 to move and extend the outrigger beam 200 from the outrigger frame 100 . Support legs 310 of outrigger support 300 are then lowered onto support surface S by operation of support cylinders 320 to support the outrigger assembly on the support surface, ultimately reaching the position shown in FIG. 6B.

[42] To reach the first semi-extended position P2 of FIG. 5C, the second outrigger beam actuator 160 moves the second piston portion 162 to the second cylinder as shown for the intermediate position of FIG. 5B. Extension from section 161 is operated to move and extend outrigger beam 200 from outrigger frame 100 . In this operation, the slider element 500 does not move relative to the outrigger frame 100 because the first end 501 of the slider element 500 is fixedly connected to the first and second cylinder portions 151,161. First outrigger beam actuator 150 is then operated to extend first piston portion 152 from first cylinder portion 151 to further move and extend outrigger beam 200 from outrigger frame 100, FIG. 5C. reach the outrigger beam position shown in .

The operation of the first and second outrigger beam actuators 150, 160 can also overlap to reach the outrigger beam position of FIG. 4D from the outrigger beam position of FIG. 4C. This is equivalent to what was described above with respect to FIG. 5C. The second end 502 of the slider element 500 will slide over the outrigger frame 100 and eventually abut the first stop 111 on the outrigger frame. When the first and second outrigger beam actuators 150, 160 are operated to move the outrigger beams to a position corresponding to the extended position P1, the cam actuator 450 moves the cam 400 about its axis of rotation 410. It is operated to rotate to move the cam into the first recess 211 above the outrigger beam. Support legs 310 of outrigger support 300 are then lowered onto support surface S by operation of support cylinders 320 to support the outrigger assembly on the support surface, ultimately reaching the position shown in FIG. 4D.
