DETAILED DESCRIPTION

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0053] The embodiments of the present application will be described below in connection with Figures 1 to 15 , description of the boom trolley and working machine according to the embodiments of the present application.

[0054] According to an embodiment of the present application, on one hand, a boom trolley is provided, as shown in Figures 10 to 15 , the boom trolley comprises a trolley head module 1, a trolley tail module 2, and an upper trolley bracket 4.

[0055] Specifically, as shown in Figure 1As shown, the trolley head module 1 is an essential component of the boom trolley and includes a first frame 101, a first running device 102, and a first connecting assembly 11. The first running device 102 is connected to the first frame 101, and the first connecting assembly 11 is arranged on one side of the first frame 101. The trolley head module 1 also includes a head mounting plate 103, which can be installed with other functional components and serves as a fixing platform for related electrical components, related switch panels, and various tow hook connection parts.

[0056] like Figure 2 As shown, the trolley tail module 2 is an essential component of the boom trolley and includes a second frame 201, a second running device 202, and a second connecting assembly 12. The second running device 202 is connected to the second frame 201, and the second connecting assembly 12 is arranged on one side of the second frame 201. The first connecting assembly 11 and the second connecting assembly 12 match to enable the trolley head module 1 to be connected to the trolley tail module 2. In addition, the trolley tail module 2 also includes a tail mounting plate 203, on which other functional components such as a bumper, a taillight mounting panel, and a sign can be installed. It should be noted that the running device is a mature product in the relevant technology, so its specific structure will not be repeated here.

[0057] The upper bracket 4 is an essential component of the boom trolley, used to lift the boom and serve as the boom support part. The upper bracket 4 is coupled to the upper bracket 4 by welding the connecting bracket on the crane boom. Figure 10 As shown, the second frame 201 can be connected to the first frame 101 to form a frame body 5 , and the upper bracket 4 is arranged on the frame body 5 .

[0058] With such an arrangement, the trolley head module 1, the trolley tail module 2 and the upper bracket 4 can be quickly assembled to form a traveling trolley, which can move with the entire machine and support the crane boom without the need to disassemble the boom, saving time and effort and being simple to operate. The split modular design facilitates transportation and maintenance, thereby reducing costs.

[0059] Furthermore, in some embodiments of the present invention, the boom trolley further includes at least one trolley mid-module 3. It should be noted that the number of trolley mid-modules 3 can be determined based on actual design requirements, and boom trolleys with different axle numbers, such as two, three, or four axles, can be constructed to suit usage scenarios with different weight requirements. This solves the problem that the same crane needs to be equipped with multiple boom trolleys with different axle numbers due to differences in terrain and roads in different regions, and that cranes of different tonnages cannot use the same boom trolley due to different weight differences.

[0060] like Figure 3As shown, the middle module 3 of the trolley includes a third trolley frame 301 and a third walking device 302 connected with the third trolley frame 301. It should be noted that the walking device is a mature product in the related art, and thus its specific structure is not described herein. The middle module 3 of the trolley is an optional component of the boom trolley, and different numbers of combinations form boom trolleys with different numbers of shafts. If the middle module 3 of the trolley is not selected, for example, as shown in Figure 10 , a two-shaft boom trolley is formed.

[0061] As shown in Figure 3 , the first end 3011 of the third trolley frame 301 is provided with a second connecting assembly 12, and the second end 3012 of the third trolley frame 301 is provided with a first connecting assembly 11, so that the trolley head module 1, one or more middle modules 3 of the trolley, and the trolley tail module 2 can be sequentially connected through the cooperation of the first connecting assembly 11 and the second connecting assembly 12 to form a trolley frame body 5 including the first trolley frame 101, one or more third trolley frames 301, and the second trolley frame 201.

[0062] For example, as shown in Figure 13 , the boom trolley is composed of the trolley head module 1, one middle module 3 of the trolley, and the trolley tail module 2 to form a three-shaft boom trolley, wherein the first trolley frame 101, the third trolley frame 301, and the second trolley frame 201 are sequentially connected through the cooperation of the first connecting assembly 11 and the second connecting assembly 12 to form the trolley frame body 5.

[0063] If the middle module 3 of the trolley is increased to two, a four-shaft boom trolley is formed by the trolley head module 1, two middle modules 3 of the trolley, and the trolley tail module 2, wherein the first trolley frame 101, the two third trolley frames 301, and the second trolley frame 201 are sequentially connected through the cooperation of the first connecting assembly 11 and the second connecting assembly 12 to form the trolley frame body 5. Similarly, a five-shaft boom trolley, a six-shaft boom trolley, and the like can be constructed.

[0064] In this way, the modular design is adopted, and different numbers of shafts of the boom trolley can be formed by combining the trolley head module 1, the trolley tail module 2, and different numbers of middle modules 3 of the trolley, so that the boom trolley can be freely combined according to the weight requirements of the crane, the use requirements of the same crane for different regions, and the use requirements of different tonnage cranes for a type of boom trolley, thereby achieving multi-scene application, greatly improving the versatility and flexibility of the boom trolley, reducing the types and numbers of the boom trolley, reducing the manufacturing cost, and facilitating transportation and maintenance.

[0065] In some embodiments of the present application, the arm support trolley further comprises at least one intermediate connecting frame 6. It is understood that the number of intermediate connecting frames 6 can be determined according to actual design requirements. The intermediate connecting frame 6 is an optional component of the arm support trolley. Compared with the middle trolley module 3, the intermediate connecting frame 6 reduces the walking device part. By combining different numbers, the length and wheelbase of the trolley can be changed, and the arm support trolley with different wheelbases can be formed to meet the application scenarios with minimum wheelbase requirements.

[0066] Specifically, as shown in Figure 4 the first connecting end 601 of the intermediate connecting frame 6 is provided with the second connecting assembly 12, and the second connecting end 602 of the intermediate connecting frame 6 is provided with the first connecting assembly 11, so that the trolley head module 1, one or more intermediate connecting frames 6, and the trolley tail module 2 can be connected in sequence through the cooperation of the first connecting assembly 11 and the second connecting assembly 12 to form the trolley frame main body 5 including the first trolley frame 101, one or more intermediate connecting frames 6, and the second trolley frame 201.

[0067] For example, as shown in Figure 11 the arm support trolley is composed of the trolley head module 1, the trolley tail module 2, and one intermediate connecting frame 6 to form a two-axle extended arm support trolley, which can be applied to narrow and sharp curved roads. Among them, the first trolley frame 101, one intermediate connecting frame 6, and the second trolley frame 201 are connected in sequence through the cooperation of the first connecting assembly 11 and the second connecting assembly 12 to form the trolley frame main body 5.

[0068] Alternatively, as shown in Figure 12 the arm support trolley is composed of the trolley head module 1, the trolley tail module 2, and two intermediate connecting frames 6 to form a two-axle super-long arm support trolley, which can be applied to areas with minimum wheelbase requirements. Among them, the first trolley frame 101, two intermediate connecting frames 6, and the second trolley frame 201 are connected in sequence through the cooperation of the first connecting assembly 11 and the second connecting assembly 12 to form the trolley frame main body 5.

[0069] In this way, by combining different numbers of intermediate connecting frames 6, the wheelbase of the arm support trolley can be adjusted according to actual use requirements placed between the trolley head module 1 and the trolley tail module 2, so as to meet the flexibility requirements of road sharp curves or meet the minimum wheelbase requirements of different areas, further expanding the application range of the arm support trolley and improving the versatility and applicability of the arm support trolley.

[0070] In some embodiments of the present application, the arm support trolley further comprises at least one trolley middle module 3 and at least one intermediate connecting frame 6. The trolley middle module 3 comprises a third trolley frame 301 and a third walking device 302, and the third walking device 302 is connected with the third trolley frame 301.

[0071] Among them, as shown in Figure 3As shown, the first end 3011 of the third frame 301 is provided with the second connecting assembly 12, the second end 3012 of the third frame 301 is provided with the first connecting assembly 11, and as shown in Figure 4 As shown, the first connecting end 601 of the intermediate connecting frame 6 is provided with the second connecting assembly 12, and the second connecting end 602 of the intermediate connecting frame 6 is provided with the first connecting assembly 11, so that the trolley head module 1, one or more trolley middle modules 3, one or more intermediate connecting frames 6, and the trolley tail module 2 can be connected in sequence through the cooperation of the first connecting assembly 11 and the second connecting assembly 12 to form the frame body 5 including the first frame 101, one or more third frames 301, one or more intermediate connecting frames 6, and the second frame 201.

[0072] For example, as shown in Figure 14 As shown, the arm support trolley is composed of a trolley head module 1, a trolley tail module 2, one trolley middle module 3, and one intermediate connecting frame 6 to form a three-axis long arm support trolley, wherein the first frame 101, one third frame 301, one intermediate connecting frame 6, and the second frame 201 are connected in sequence through the cooperation of the first connecting assembly 11 and the second connecting assembly 12 to form the frame body 5.

[0073] Alternatively, as shown in Figure 15 As shown, the arm support trolley is composed of a trolley head module 1, a trolley tail module 2, one trolley middle module 3, and two intermediate connecting frames 6 to form a three-axis long arm support trolley, wherein the first frame 101, one third frame 301, one intermediate connecting frame 6, and the second frame 201 are connected in sequence through the cooperation of the first connecting assembly 11 and the second connecting assembly 12 to form the frame body 5.

[0074] In this way, by combining different numbers of trolley middle modules 3 and intermediate connecting frames 6, and placing them between the trolley head module 1 and the trolley tail module 2 according to actual use requirements, different combinations of different numbers of axes and different trolley wheelbase can be achieved, further expanding the application scenarios of the arm support trolley and improving the versatility and flexibility of the arm support trolley.

[0075] In some embodiments of the present application, the arm support trolley has a first direction X, which is the width direction of the arm support trolley in this embodiment. Specifically, the arm support trolley further includes a plurality of first hinged members 7, as shown in Figure 10 As shown, the first hinged members 7 extend along the first direction X, and the first connecting assembly 11 and the second connecting assembly 12 are hinged through the first hinged members 7. It should be noted that the number of first hinged members 7 can be determined according to actual design requirements.

[0076] For example, as shown in Figures 10 to 12As shown in the figure, in the two-axis boom trolley, the first frame 101 and the second frame 201, the first frame 101 and the intermediate connecting frame 6, the second frame 201 and the intermediate connecting frame 6, and the two intermediate connecting frames 6 are hingedly connected in the first direction X by the first hinge 7.

[0077] For another example, as shown in the figure, Figures 13 to 15 in the three-axis boom trolley, the first frame 101 and the third frame 301, the second frame 201 and the third frame 301, and the third frame 301 and the intermediate connecting frame 6 are hingedly connected in the first direction X by the first hinge 7. For yet another example, in the four-axis boom trolley, the two third frames 301 are hingedly connected in the first direction X by the first hinge 7.

[0078] In this way, each frame body in the frame main body 5, such as the first frame 101, the second frame 201, the third frame 301, and the intermediate connecting frame 6, is hingedly connected to each other in the first direction X by the first hinge 7, so as to rotate around the X axis, thereby increasing the flexibility and adaptability of the frame main body 5, and further in actual application, the frame main body 5 can adapt to various complex road conditions such as road surface ups and downs, and by allowing the relative rotation between the frame bodies, the frame main body 5 can better adapt to these changes, thereby improving the stability and comfort of driving.

[0079] Specifically, in some embodiments of the present application, as shown in the figure, Figure 6 the first hinge 7 comprises a first hinge shaft 701 and a pair of first stop pieces 702. Specifically, as shown in the figure, Figure 10 the first hinge shaft 701 extends along the first direction X. As shown in the figure, Figure 6 the pair of first stop pieces 702 are respectively arranged at the two ends of the first hinge shaft 701. Specifically, the first stop piece 702 and the first hinge shaft 701 can be connected by a bolt assembly, which is convenient for installation and disassembly.

[0080] As shown in the figure, Figures 1 to 4 in the frame main body 5, each frame body such as the first frame 101, the second frame 201, the third frame 301, and the intermediate connecting frame 6 is provided with a first shaft hole 9 and a hinge plate 10 corresponding to each other along the first direction X, and the hinge plate 10 is provided with a second shaft hole 1001 opposite to the first shaft hole 9. When installing, as shown in the figure, Figure 8 at the connection between the two frame bodies, the first shaft hole 9 and the second shaft hole 1001 are aligned, the first hinge shaft 701 is then penetrated through the first shaft hole 9 and the second shaft hole 1001, and then the first stop piece 702 is installed at the two ends of the first hinge shaft 701, so as to rotationally connect the two frame bodies.

[0081] With such a configuration, the first hinge shaft 701 and the pair of first stops 702 cooperate with each other to achieve a rotational connection between adjacent frame units. In addition, the first stops 702 can also effectively prevent the first hinge 7 from falling off the frame body 5, thereby ensuring a reliable connection of the frame body 5 and improving the stability and safety of the connection.

[0082] In some embodiments of the present invention, the boom trolley has a second direction Z intersecting the first direction X. In this embodiment, the second direction Z is the height direction of the boom trolley and is perpendicular to the first direction X. Specifically, the boom trolley further includes a plurality of second hinges 8 extending along the second direction Z. The first connecting assembly 11 and the second connecting assembly 12 are articulated via the second hinges 8. It should be noted that the number of second hinges 8 can be determined based on actual design requirements.

[0083] For example, Figures 10 to 12 As shown, in the two-axle boom trolley, the first frame 101 and the second frame 201, the first frame 101 and the middle connecting frame 6, the second frame 201 and the middle connecting frame 6, and the two middle connecting frames 6 are hinged in the second direction Z through the second hinge 8.

[0084] For example, Figures 13 to 15 As shown, in a three-axle boom trolley, the first frame 101 and the third frame 301, the second frame 201 and the third frame 301, and the third frame 301 and the intermediate connecting frame 6 are articulated in the second direction Z via a second articulated member 8. For another example, in a four-axle boom trolley, the two third frames 301 are articulated in the second direction Z via a second articulated member 8.

[0085] With this arrangement, the individual frame units in the frame body 5, such as the first frame 101, the second frame 201, the third frame 301, and the intermediate connecting frame 6, are hingedly connected to each other in the second direction Z via the second hinge 8, thereby being rotatable about the Z axis. This allows the frame body 5 to be more flexible when turning. By adjusting the relative angles between the individual frame units, the frame body 5 can better adapt to changes in curvature during turns, thereby improving the vehicle's controllability and stability.

[0086] Specifically, in some embodiments of the present invention, Figure 7 As shown, the second hinge member 8 includes a second hinge shaft 801 and a pair of second stoppers 802. Specifically, as Figure 10 As shown, the second hinge axis 801 extends along the second direction Z. Figure 7 As shown, a pair of second stoppers 802 are respectively provided at both ends of the second hinge shaft 801. Specifically, the second stopper 802 and the second hinge shaft 801 can be connected by a bolt assembly to facilitate installation and disassembly.

[0087] like Figures 1 to 4 As shown, in each frame unit of the frame body 5, such as the first frame 101, the second frame 201, the third frame 301 and the middle connecting frame 6, along the second direction Z, two adjacent connecting ends are respectively provided with a first shaft hole 9 and a hinge plate 10, and the hinge plate 10 is provided with a second shaft hole 1001 opposite to the first shaft hole 9. During installation, along the second direction Z, as shown Figure 9 As shown, at the connection of the two frame units, the first axis hole 9 and the second axis hole 1001 are aligned, and then the second hinge shaft 801 is passed through the first axis hole 9 and the second axis hole 1001, and then the second stoppers 802 are respectively installed at both ends of the second hinge shaft 801, so as to rotate and connect the two frame units.

[0088] With such a configuration, the second hinge shaft 801 and a pair of second stops 802 cooperate with each other to achieve a rotational connection between adjacent frame units. In addition, the second stops 802 can also effectively prevent the second hinge 8 from falling off the frame body 5, thereby ensuring a reliable connection of the frame body 5 and improving the stability and safety of the connection.

[0089] In some embodiments of the present invention, the boom trolley has a third direction Y that intersects the first direction X and the second direction Z in pairs. In this embodiment, the third direction Y is the length direction of the boom trolley, and the first direction X, the second direction Z and the third direction Y are perpendicular to each other.

[0090] Specifically, if Figure 10 As shown, the vehicle frame body 5 includes a pair of side beams 501 and at least two connecting brackets 502. The pair of side beams 501 are spaced apart along a first direction X, wherein the side beams 501 extend along a third direction Y. A plurality of connecting brackets 502 are spaced apart along the third direction Y, and the connecting brackets 502 are connected between the pair of side beams 501. The connecting brackets 502 can be fixed to the pair of side beams 501 by welding, bolting, or other methods.

[0091] Specifically, see Figures 10 to 15 As shown, the frame body 5 is formed by freely combining the first frame 101, the second frame 201, the third frame 301 and the middle connecting frame 6. Figures 1 to 4 As shown, the first frame 101 , the second frame 201 , the third frame 301 and the middle connecting frame 6 each include a pair of side beams 501 and a connecting bracket 502 .

[0092] In this arrangement, the side beams 501 and the connecting brackets 502 cooperate with each other to form a support frame for the trolley, providing a stable and reliable support structure, so that the frame body 5 has sufficient rigidity and stability to withstand various forces and vibrations during driving, thereby enhancing the stability and safety of the boom trolley.

[0093] Furthermore, in some embodiments of the present invention, the connecting bracket 502 includes a reinforcement 5022 and a pair of crossbeams 5021. Taking one of the frame units such as the middle connecting frame 6 as an example to illustrate this embodiment, Figure 4 As shown, a pair of cross beams 5021 are spaced apart along the third direction Y. The cross beams 5021 extend along the first direction X, and both ends of the cross beams 5021 are respectively connected to the pair of side beams 501 , for example, by welding.

[0094] The reinforcement 5022 is disposed between the pair of cross beams 5021. For example, the reinforcement 5022 may be designed in an X-shaped structure.
