DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0053] Combine the following Figures 1 to 15 , describing the boom trolley and operating machinery of an embodiment of the present invention.

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

[0055] Specifically, if Figure 1As shown, the trolley head module 1 is an essential component of the boom trolley, which 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, as a fixing platform for related electrical parts, related switch panels, and various towing hook connection parts.

[0056] like Figure 2 As shown, the trolley tail module 2 is an essential component of the boom trolley, which includes a second frame 201, a second running device 202 and a second connecting assembly 12, wherein 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. Among them, the first connecting assembly 11 and the second connecting assembly 12 match so that the trolley head module 1 can 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, a sign, etc. can be installed. It should be noted that the running device is a mature product in the relevant technology, so its specific structure, etc. will not be repeated here.

[0057] The upper bracket 4 is an essential component of the boom trolley, used to lift the boom, as the boom support part, and is coupled to the upper bracket 4 by welding a connecting support on the crane boom. Fig.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 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 travel with the whole machine and support the crane boom without disassembling the boom, saving time and effort and being simple to operate. The split modular design is convenient for transportation and maintenance, thereby reducing costs.

[0059] Furthermore, in some embodiments of the present invention, the boom trolley further includes at least one trolley middle module 3. It should be noted that the number of the trolley middle modules 3 can be specifically determined according to actual design requirements, and boom trolleys with different axle numbers such as two axles, three axles, and four axles can be constructed to be suitable for use scenarios with different weight requirements, so as to solve 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 trolley middle module 3 includes a third frame 301 and a third walking device 302, and the third walking device 302 is connected to the third frame 301. It should be noted that the walking device is a mature product in the relevant technology, so its specific structure is not repeated here. Among them, the trolley middle module 3 is an optional component of the boom trolley. Through the combination of different quantities, the boom trolley with different axle numbers is formed. If the trolley middle module 3 is not selected, such as Fig.10 As shown, a two-axis boom trolley is formed.

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

[0062] For example, Fig.13 As shown, the boom trolley is composed of a trolley head module 1, a trolley middle module 3 and a trolley tail module 2 to form a three-axis boom trolley, wherein a first frame 101, a third frame 301 and a second frame 201 are connected in sequence through a first connecting component 11 and a second connecting component 12 to form a frame body 5.

[0063] If the number of middle modules 3 of the trolley increases to two, the trolley head module 1, the two middle modules 3 of the trolley and the trolley tail module 2 form a four-axis boom trolley, wherein the first frame 101, the two third frames 301 and the second frame 201 are sequentially connected through the first connecting assembly 11 and the second connecting assembly 12 to form a frame body 5. By analogy, a five-axis boom trolley, a six-axis boom trolley and the like can be constructed respectively.

[0064] Such arrangement, with a split modular design, can form boom trolleys with different numbers of axles by combining the trolley head module 1, the trolley tail module 2 and different numbers of trolley middle modules 3. Such arrangements can be freely combined according to the weight requirements of the cranes, thereby satisfying the use requirements of the same crane in different regions, as well as the use requirements of different tonnage cranes to share a same boom trolley, thus realizing multi-scenario application, greatly improving the versatility and flexibility of the boom trolley, reducing the types and quantity of the boom trolleys, reducing manufacturing costs, and facilitating transportation and maintenance.

[0065] In other embodiments of the present invention, the boom trolley further includes at least one intermediate connecting frame 6. It is understandable that the number of the intermediate connecting frames 6 can be specifically determined according to actual design requirements. The intermediate connecting frame 6 is an optional component of the boom trolley. Compared with the middle module 3 of the trolley, the running device part is reduced. By combining different numbers, the length and wheelbase of the trolley can be changed to form boom trolleys with different wheelbases, which can meet the application scenarios with minimum wheelbase requirements.

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

[0067] For example, Fig.11 As shown, the boom trolley is composed of a trolley head module 1, a trolley tail module 2 and an intermediate connecting frame 6 to form a two-axle extended boom trolley, which can be used on narrow and sharp roads. Among them, the first frame 101, an intermediate connecting frame 6 and the second frame 201 are connected in sequence through the first connecting component 11 and the second connecting component 12 to form a frame body 5.

[0068] Or, if Fig.12 As shown, the boom trolley is composed of a trolley head module 1, a trolley tail module 2 and two intermediate connecting frames 6 to form a two-axle super-long boom trolley, which can be used in areas with minimum wheelbase requirements. Among them, the first frame 101, the two intermediate connecting frames 6 and the second frame 201 are connected in sequence through the first connecting component 11 and the second connecting component 12 to form a frame body 5.

[0069] In this way, by combining different numbers of intermediate connecting frames 6, they are placed between the trolley head module 1 and the trolley tail module 2 according to actual usage requirements, so that the wheelbase of the boom trolley can be adjusted to meet application scenarios with different wheelbase requirements, such as meeting the flexibility requirements when making sharp turns in the road or meeting the minimum wheelbase requirements in different areas, further expanding the application scope of the boom trolley and improving the versatility and applicability of the boom trolley.

[0070] In some other embodiments of the present invention, the boom 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 frame 301 and a third walking device 302, and the third walking device 302 is connected to the third frame 301.

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

[0072] For example, Fig.14 As shown, the boom trolley is composed of a trolley head module 1, a trolley tail module 2, a trolley middle module 3 and an intermediate connecting frame 6 to form a three-axis extended boom trolley, wherein a first frame 101, a third frame 301, an intermediate connecting frame 6 and a second frame 201 are connected in sequence through a first connecting component 11 and a second connecting component 12 to form a frame body 5.

[0073] Or, if Fig.15 As shown, the boom trolley is composed of a trolley head module 1, a trolley tail module 2, a trolley middle module 3 and two intermediate connecting frames 6 to form a three-axis extra-long boom trolley, wherein a first frame 101, an intermediate connecting frame 6, a third frame 301, another intermediate connecting frame 6 and a second frame 201 are connected in sequence through a first connecting component 11 and a second connecting component 12 to form a frame body 5.

[0074] In this way, by combining different numbers of trolley middle modules 3 and intermediate connecting frames 6, they are placed between the trolley head module 1 and the trolley tail module 2 according to actual usage requirements, thereby realizing a combination of different numbers of axles and different trolley wheelbases, further expanding the application scenarios of the boom trolley and improving the versatility and flexibility of the boom trolley.

[0075] In some embodiments of the present invention, the boom trolley has a first direction X. In this embodiment, the first direction X is the width direction of the boom trolley. Specifically, the boom trolley further includes a plurality of first hinged members 7, such as Fig.10 As shown, the first hinge 7 extends along the first direction X, and the first connection component 11 and the second connection component 12 are hingedly connected via the first hinge 7. It should be noted that the number of the first hinges 7 can be specifically determined according to actual design requirements.

[0076] For example, Figures 10 to 12As shown, in the two-axle arm 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 first direction X through the first hinge 7.

[0077] For example, Figures 13 to 15 As shown, in a 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 hinged in the first direction X through a first hinge 7. For another example, in a four-axis boom trolley, two third frames 301 are hinged in the first direction X through a first hinge 7.

[0078] With such arrangement, each frame unit in the frame body 5, such as the first frame 101, the second frame 201, the third frame 301 and the middle connecting frame 6, is hingedly connected to each other in the first direction X through the first hinge 7, so that it can rotate around the X-axis, thereby increasing the flexibility and adaptability of the frame body 5. Furthermore, in actual application, the frame body 5 can adapt to various complex road conditions such as uneven road surfaces. By allowing the frame units to rotate relative to each other, the frame body 5 can better adapt to these changes and improve the driving stability and comfort.

[0079] Specifically, in some embodiments of the present invention, Figure 6 As shown, the first hinged member 7 includes a first hinged shaft 701 and a pair of first stoppers 702. Specifically, as Fig.10 As shown, the first hinge axis 701 extends along the first direction X. Figure 6 As shown, a pair of first stoppers 702 are respectively disposed at two ends of the first hinge shaft 701. Specifically, the first stopper 702 and the first hinge shaft 701 can be connected by a bolt assembly to facilitate installation and disassembly.

[0080] like Figures 1 to 4 As shown, in each frame unit in 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 first direction X, 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 first direction X, as Figure 8 As shown, at the connection of the two frame units, the first axial hole 9 and the second axial hole 1001 are aligned, and then the first hinge shaft 701 passes through the first axial hole 9 and the second axial hole 1001, and then the first stopper 702 is respectively installed at both ends of the first hinge shaft 701, so as to rotatably connect the two frame units.

[0081] With such arrangement, the first hinge shaft 701 and a pair of first stops 702 cooperate with each other to achieve a rotational connection between adjacent frame units, and the first stops 702 can also effectively prevent the first hinge 7 from falling off the frame body 5, so that the frame body 5 is reliably connected, thereby 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 with the first direction X. In this embodiment, the second direction Z is the height direction of the boom trolley, and the second direction Z is perpendicular to the first direction X. Specifically, the boom trolley further includes a plurality of second hinges 8, the second hinges 8 extend along the second direction Z, and the first connecting assembly 11 and the second connecting assembly 12 are hingedly connected through the second hinges 8. It should be noted that the number of the second hinges 8 can be specifically determined according to actual design requirements.

[0083] For example, Figures 10 to 12 As shown, in the two-axle arm 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-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 hinged in the second direction Z through a second hinge 8. For another example, in a four-axis boom trolley, two third frames 301 are hinged in the second direction Z through a second hinge 8.

[0085] With such arrangement, each frame unit in the frame body 5, such as the first frame 101, the second frame 201, the third frame 301 and the middle connecting frame 6, is hingedly connected to each other in the second direction Z through the second hinge 8, so that the frame body 5 can rotate around the Z axis, so that the frame body 5 can be more flexible when turning. By adjusting the relative angles between the frame units, the frame body 5 can better adapt to the curvature change when turning, thereby improving the controllability and stability of the vehicle.

[0086] Specifically, in some embodiments of the present invention, Figure 7 As shown, the second hinged member 8 includes a second hinged shaft 801 and a pair of second stoppers 802. Specifically, as Fig.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 disposed 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 in 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 Fig. 9 As shown, at the connection of the two frame units, the first axial hole 9 and the second axial hole 1001 are aligned, and then the second hinge shaft 801 passes through the first axial hole 9 and the second axial hole 1001, and then the second stoppers 802 are respectively installed at both ends of the second hinge shaft 801, so as to rotatably connect the two frame units.

[0088] With such arrangement, 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, and the second stops 802 can also effectively prevent the second hinge 8 from falling off the frame body 5, so that the frame body 5 is reliably connected, thereby improving the stability and safety of the connection.

[0089] In some embodiments of the present invention, the boom trolley has a third direction Y intersecting 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 Fig.10 As shown, the 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 the like.

[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 way, 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] Further, in some embodiments of the present invention, the connecting bracket 502 includes a reinforcing member 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 two ends of the cross beams 5021 are respectively connected to a pair of side beams 501 , for example, by welding.

[0094] The reinforcement member 5022 is disposed between a pair of cross beams 5021. For example, the reinforcement member 5022 may be designed in an X-shaped structure. In the third direction Y, the reinforcement member 5022 is respectively connected to the pair of cross beams 5021, such as by welding, and in the first direction X, the reinforcement member 5022 is respectively connected to the pair of side beams 501, such as by welding.

[0095] With such arrangement, the reinforcement 5022 and the pair of cross beams 5021 cooperate with each other to form a stable connection with the pair of side beams 501, thereby greatly enhancing the overall structural strength of the frame body 5, thereby enabling the boom trolley to reliably support the boom.

[0096] In some embodiments of the present invention, Figure 5 As shown, the vehicle bracket 4 includes a support frame 401, a connecting base 402, and a support seat 403. Specifically, as Figure 5 As shown, the support frame 401 includes a top plate 4012 and a plurality of support columns 4011, the plurality of support columns 4011 are mounted on the lower surface of the top plate 4012, and the plurality of support columns 4011 are spaced apart along the circumference of the top plate 4012 to form an overall support frame. A first reinforcing rib 4013 and a pair of second reinforcing ribs 4014 are connected between two adjacent support columns 4011, forming a structure similar to the connecting bracket 502, further improving the overall stability of the support frame 401 to ensure reliable support of the arm frame.

[0097] The connecting base 402 is disposed on one side of the support frame 401 close to the frame body 5, and the connecting base 402 is connected to the frame body 5. Specifically, there are multiple connecting bases 402, which are respectively installed at the lower ends of multiple support columns 4011. The connecting base 402 and the frame body 5 are respectively provided with multiple mounting holes, and the connecting base 402 can be fixed to the frame body 5 by inserting a bolt assembly. It can be understood that, see Figures 10 to 15 As shown, in the third direction Y, the installation position of the on-board bracket 4 can be specifically determined according to actual design requirements.

[0098] The support seat 403 is arranged on a side of the support frame 401 away from the vehicle frame body 5, and the support seat 403 is used to connect the arm. Specifically, there are multiple support seats 403, which are respectively installed on the upper surface of the top plate 4012, and the multiple support seats 403 are distributed at intervals along the circumference of the top plate 4012, for example, arranged at each corner position of the top plate 4012. The support seat 403 has an opening 4031, and a connecting support is correspondingly arranged on the arm. The connecting support is inserted into the opening 4031, and the arm is connected to the support seat 403 by inserting a bolt assembly.

[0099] With such arrangement, the support frame 401, the connecting base 402 and the support seat 403 cooperate with each other to form a stable support structure, which can reliably bear the weight of the arm and various forces generated, thereby ensuring the stability and safety of the trolley.

[0100] In summary, the embodiment of the present invention provides a boom trolley, including a trolley head module 1, a trolley tail module 2, a trolley middle module 3, a vehicle bracket 4, an intermediate connecting frame 6, a first hinge 7, and a second hinge 8, etc., realizing a split design. By freely combining and assembling the above modules in different quantities according to actual use requirements, various types of boom trolleys with different numbers of axles and different wheelbases can be constructed, including but not limited to Figures 10 to 15 The two-axis and three-axis boom trolley combination examples shown can also form more extended examples such as four-axis trolley combination and five-axis trolley combination. It is easy to install and has strong feasibility. It can adapt to the use requirements of the same crane with different weight limits, and can also adapt to the use requirements of different weight differences of cranes of different tonnages, while increasing the flexibility and practicality of the trolley.

[0101] According to an embodiment of the present invention, on the other hand, a working machine is also provided. It can be understood that the working machine includes but is not limited to a crane, an excavator, etc. Specifically, a crane is taken as an example to illustrate this embodiment. The working machine includes a boom trolley as in the above-mentioned embodiments. With such a configuration, the trolley head module, the trolley tail module and the upper vehicle bracket can be quickly assembled to form a walking trolley, which can travel with the whole machine to support the crane boom without disassembling the boom, saving time and effort, and being simple to operate. In addition, the split modular design is adopted, which is convenient for transportation and maintenance, and reduces costs. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the above-mentioned boom trolley, so it will not be repeated here.

[0102] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
