Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a chassis structure for a work machinery and the work machinery itself. Background Technology

[0002] With the development of engineering technology, engineering operations have placed higher demands on construction machinery. For example, in recent years, with the continuous increase in borehole diameter, drilling operations have placed higher demands on rotary drilling rigs. This requires that the width of the tracked chassis of tracked rotary drilling rigs be increased to provide a larger longitudinal support span. Similarly, other construction machinery also faces the same requirements for their chassis structures, necessitating a wider chassis during construction to ensure the stability of the machinery.

[0003] While existing technologies can increase chassis width, this leads to an increase in the size and weight of the machinery, increasing transportation difficulties. Furthermore, existing telescopic chassis structures often fail to meet the required structural strength requirements for the machinery. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a chassis structure for a work machinery and the work machinery itself.

[0005] On one hand, the present invention provides a chassis structure for a work machinery, comprising:

[0015] A pair of second connecting seats are mounted on the second traveling mechanism. Each second connecting seat has a second through hole for the second extension to pass through. The second connecting seat is detachably connected to the second extension section.

[0016] According to the present invention, the first telescopic mechanism is a first telescopic cylinder, and the second telescopic mechanism is a second telescopic cylinder.

[0017] The first telescopic hydraulic cylinder has one end connected to the main frame and the other end detachably connected to the first traveling mechanism. The second telescopic hydraulic cylinder has one end connected to the main frame and the other end detachably connected to the second traveling mechanism.

[0018] According to a chassis structure for a work machinery provided by the present invention, limiting buckles are provided at intervals on the side walls of the first extension and the second extension. Limiting holes are provided on the first extension section, the second extension section, the first connecting seat, and the second connecting seat. Each limiting buckle can move with the first extension and the second extension section in the first through hole, the second through hole, the first through hole, or the second through hole, and can be pulled out from the limiting hole to achieve limiting.

[0019] According to the present invention, in a chassis structure for a work machinery, the first extension section and the first connecting seat, and the second extension section and the second connecting seat are connected by pins.

[0044] The following is combined Figures 1 to 4 This invention describes a chassis structure for a work machinery and the work machinery itself, as provided in an embodiment of the invention. It should be understood that the following description is merely an illustrative embodiment of the invention and does not constitute any particular limitation on the invention.

[0045] On one hand, embodiments of the present invention provide a chassis structure for a work machinery, such as Figure 1 As shown, the chassis structure of this work machinery includes:

[0046] The main frame 100 has an extension on which an internal accommodating chamber is formed;

[0047] The extension section has a through hole for the extension to pass through and move;

[0048] The traveling mechanism is detachably connected to the extension section.

[0049] The telescopic mechanism is detachably installed in the receiving cavity, with one end of the telescopic mechanism detachably connected to the main frame 100 and the other end passing through the extension section and detachably connected to the traveling mechanism.

[0050] For example, in one embodiment of the invention, the shape and size of the through hole in the extension section are adapted to the shape and size of the extension, so that the extension section can provide support to the extension while increasing the width of the chassis, and the extension can move through the through hole of the extension section.

[0051] In this chassis structure of the work machinery, the telescopic mechanism is housed within the receiving cavity of the extension section. One end of the telescopic mechanism is connected to the main frame 100, and the other end is connected to the traveling mechanism. This allows for flexible adjustment of the width of the chassis structure to meet different operational needs and significantly improves the working stability of the work machinery. Simultaneously, the chassis structure allows for the disassembly of the extension section and the shortening of the telescopic mechanism to reduce the chassis volume, facilitating transportation. Furthermore, the extension section in this chassis structure can telescopically move within the through-hole of the extension section under the drive of the telescopic mechanism, increasing the support strength of the extension section and further enhancing the support strength of the chassis structure.

[0052] In one embodiment of the invention, the edges of the main frame 100 form a pair of first extensions 101 and a pair of second extensions 102 that extend in opposite directions to each other, and the telescopic mechanism includes a first telescopic mechanism and a second telescopic mechanism.

[0053] Each of the first extensions 101 has a first receiving chamber 103, and a first telescopic mechanism is detachably installed in each of the first receiving chambers 103. Each of the second extensions 102 has a second receiving chamber, and a second telescopic mechanism is detachably installed in each of the second receiving chambers.

[0054] For example, such as Figure 1 As shown, in the chassis structure of this work machinery, the edges of the main frame 100 form a pair of first extensions 101 and a pair of second extensions 102 that extend in opposite directions. Each first extension 101 has a first receiving chamber 103, and a first telescopic mechanism is detachably installed in each first receiving chamber 103. One end of the first telescopic mechanism is connected to the main frame 100, and the other end is connected to the traveling mechanism.

[0055] Each of the second extensions 102 has a second receiving chamber, and a second telescopic mechanism is detachably installed in each of the second receiving chambers. One end of the second telescopic mechanism is connected to the main frame 100, and the other end is connected to the running gear.

[0056] The extension section has a through hole for the extension to pass through and move, and the extension section is detachably connected to the traveling mechanism.

[0057] In one embodiment of the present invention, the extension section includes a first extension section 201 and a second extension section 202. Each first extension 101 is provided with a first extension section 201, and each first extension section 201 has a first through hole 203 for each first extension 101 to pass through and move. Each second extension 102 is provided with a second extension section 202, and each second extension section 202 has a second through hole 204 for each second extension 102 to pass through and move.

[0058] Specifically, such as Figure 1 As shown, in the chassis structure of this work machinery, the edges of the main frame 100 form a pair of first extensions 101 and a pair of second extensions 102 that extend in opposite directions. Each first extension 101 has a first receiving chamber 103, and a first telescopic mechanism is detachably installed in each first receiving chamber 103. One end of the first telescopic mechanism is detachably connected to the main frame 100, and the other end is detachably connected to the traveling mechanism.

[0059] Each of the second extensions 102 has a second receiving chamber, and a second telescopic mechanism is detachably installed in each of the second receiving chambers. One end of the second telescopic mechanism is connected to the main frame 100, and the other end is connected to the running gear.

[0060] The extension section includes a first extension section 201 and a second extension section 202. Each first extension 101 is provided with a corresponding first extension section 201, and each first extension section 201 has a first through hole 203 for the first extension 101 to pass through and move. Similarly, each second extension 102 is provided with a corresponding second extension section 202, and each second extension section 202 has a second through hole 204 for the second extension 102 to pass through and move. Each first extension section 201 and each second extension section 202 are detachably connected to the traveling mechanism.

[0061] For example, the chassis structure of this operating machinery is a tracked chassis structure for rotary drilling rigs. Figures 2 to 4 As shown, the three states of the tracked chassis structure are schematically represented, namely the first state, the second state, and the third state.

[0062] Among them, the first state is as follows Figure 2 The image shows the state of the tracked chassis structure at its maximum width, that is, the state when the tracked chassis structure can provide the maximum longitudinal support span for the rotary drilling rig.

[0063] Among them, the second state is as follows Figure 3 The image shows the tracked chassis structure at its intermediate width value. The intermediate width value here refers to any desired width value within the range of the maximum and minimum width values.

[0064] Among them, the third state is as follows Figure 4 The image shows the tracked chassis structure at its minimum width, meaning that the tracked chassis structure can retract to its minimum volume limit position.

[0065] When the tracked chassis structure is in its first state, the traveling mechanism moves to its outermost position under the drive of the first and second telescopic mechanisms, respectively, so that the width of the tracked chassis structure reaches its maximum value. At this time, the tracked chassis structure can provide the maximum longitudinal support span for the rotary drilling rig, enabling the rotary drilling rig to drive special large piles.

[0066] When the tracked chassis structure is in the second state, the traveling mechanism moves outward to the desired position under the drive of the first and second telescopic mechanisms. At this time, the tracked chassis structure can provide the longitudinal support span required for the rotary drilling rig to operate, and the rotary drilling rig can drive conventional piles.

[0067] When the tracked chassis structure is in the third state, the first extension section 201 and the second extension section 202 are first disassembled, and then the first telescopic mechanism and the second telescopic mechanism are respectively connected to the walking mechanism. Driven by the first telescopic mechanism and the second telescopic mechanism, the walking mechanism moves inward to the limit position so that the tracked chassis structure is retracted to the smallest volume state for convenient transportation.

[0068] In one embodiment of the present invention, the walking mechanism includes a first walking mechanism 301 and a second walking mechanism 302. The first walking mechanism 301 is arranged laterally relative to the first extension 101. The second walking mechanism 302 is arranged laterally relative to the second extension 102.

[0069] For example, such as Figure 1 As shown, in the chassis structure of this work machinery, the edges of the main frame 100 form a pair of first extensions 101 and a pair of second extensions 102 extending in opposite directions. The traveling mechanism includes a first traveling mechanism 301 and a second traveling mechanism 302. Each first extension 101 has a first receiving chamber 103, and a first telescopic mechanism is detachably installed in each first receiving chamber 103. One end of the first telescopic mechanism is detachably connected to the main frame 100, and the other end is detachably connected to the first traveling mechanism 301. The first traveling mechanism 301 is arranged laterally relative to the first extensions 101.

[0070] Each second extension 102 has a second receiving chamber, and a second telescopic mechanism is detachably installed in each second receiving chamber. One end of the second telescopic mechanism is connected to the main frame 100, and the other end is connected to the second traveling mechanism 302. The second traveling mechanism 302 is arranged laterally relative to the second extension 102.

[0071] The extension section includes a first extension section 201 and a second extension section 202. Each first extension 101 is provided with a corresponding first extension section 201, and each first extension section 201 has a first through hole 203 for the first extension 101 to pass through and move. Similarly, each second extension 102 is provided with a corresponding second extension section 202, and each second extension section 202 has a second through hole 204 for the second extension 102 to pass through and move. Each first extension section 201 is detachably connected to the first traveling mechanism 301, and each second extension section 202 is detachably connected to the second traveling mechanism 302.

[0072] For example, in one embodiment of the present invention, the telescopic mechanism can be a telescopic hydraulic cylinder. The first telescopic mechanism is a first telescopic hydraulic cylinder 401, and the second telescopic mechanism is a second telescopic hydraulic cylinder. One end of the first telescopic hydraulic cylinder 401 is connected to the main frame 100, and the other end is detachably connected to the first traveling mechanism 301. One end of the second telescopic hydraulic cylinder is connected to the main frame 100, and the other end is detachably connected to the second traveling mechanism 302.

[0073] It should be noted that the above embodiments are merely illustrative examples of the present invention and do not constitute any limitation on the present invention. Specific structural types of telescopic mechanisms include, but are not limited to, telescopic hydraulic cylinders.

[0074] Meanwhile, the descriptions of "first," "second," etc., in all embodiments of the present invention are used only to distinguish between different components or different states, and are not limited by any order.

[0075] In one embodiment of the present invention, a pair of first connecting seats 501 are installed on the first walking mechanism 301. The first connecting seat 501 is provided with a first through hole for the first extension 101 to pass through. The first connecting seat 501 is detachably connected to the first extension section 201.

[0076] A pair of second connecting seats 502 are installed on the second walking mechanism 302. The second connecting seats 502 are provided with second through holes 503 for the second extension 102 to pass through. The second connecting seats 502 are detachably connected to the second extension section 202.

[0077] Specifically, if Figure 1 As shown, in the chassis structure of this work machinery, the edges of the main frame 100 form a pair of first extensions 101 and a pair of second extensions 102 extending in opposite directions. The traveling mechanism includes a first traveling mechanism 301 and a second traveling mechanism 302. A pair of first connecting seats 501 are mounted on the first traveling mechanism 301, and each first connecting seat 501 has a first through hole for the first extension 101 to pass through. A pair of second connecting seats 502 are mounted on the second traveling mechanism 302, and each second connecting seat 502 has a second through hole 503 for the second extension 102 to pass through.

[0078] Each first extension 101 has a first receiving chamber 103, and a first telescopic mechanism is detachably installed in each first receiving chamber 103. One end of the first telescopic mechanism is detachably connected to the main frame 100, and the other end is detachably connected to the first traveling mechanism 301. The first traveling mechanism 301 is arranged laterally relative to the first extension 101.

[0079] Each second extension 102 has a second receiving chamber, and a second telescopic mechanism is detachably installed in each second receiving chamber. One end of the second telescopic mechanism is detachably connected to the main frame 100, and the other end is connected to the second traveling mechanism 302. The second traveling mechanism 302 is arranged laterally relative to the second extension 102.

[0080] The extension section includes a first extension section 201 and a second extension section 202. Each first extension 101 is provided with a corresponding first extension section 201, and each first extension section 201 has a first through hole 203 for the first extension 101 to pass through and move. Similarly, each second extension 102 is provided with a corresponding second extension section 202, and each second extension section 202 has a second through hole 204 for the second extension 102 to pass through and move. Each first extension section 201 is detachably connected to the first traveling mechanism 301, and each second extension section 202 is detachably connected to the second traveling mechanism 302.

[0081] It should be noted that the specific shapes and dimensions of the first through hole 203, the second through hole 204, the first through hole, and the second through hole 503 are adapted to the shapes and dimensions of their corresponding first extensions 101 and second extensions 102, so that the first extension section 201, the second extension section 202, the first connecting seat 501, and the second connecting seat 502 can support the first extensions 101 and the second extensions 102. Simultaneously, the first extensions 101 and the second extensions 102 can move and pass through the first through hole 203, the second through hole 204, the first through hole, and the second through hole 503.

[0082] For example, in one embodiment of the present invention, the first extension section 201 and the first connecting seat 501, and the second extension section 202 and the second connecting seat 502 are connected by a pin 801.

[0083] Or, such as Figure 1 As shown, in one embodiment of the present invention, the top ends of the first extension section 201 and the first connecting seat 501, and the second extension section 202 and the second connecting seat 502 are connected by a pin 801. Furthermore, the side edges of the mounting surfaces of the first extension section 201 and the first connecting seat 501, and the second extension section 202 and the second connecting seat 502 are connected by a plurality of screws 802.

[0084] As described in the above embodiments, in this work machinery chassis structure, the top ends of the first extension section 201 and the first connecting seat 501, and the second extension section 202 and the second connecting seat 502, are connected by pins 801. Furthermore, the side edges of the mounting surfaces of the first extension section 201 and the first connecting seat 501, and the second extension section 202 and the second connecting seat 502, are connected by multiple screws 802. This effectively solves the problem of high stress at the connection points of the first extension section 201 and the first connecting seat 501, and the second extension section 202 and the second connecting seat 502, thereby effectively protecting the first extension section 201, the second extension section 202, the first connecting seat 501, and the second connecting seat 502. This extends the service life of the work machinery chassis structure.

[0085] In one embodiment of the present invention, limiting buckles are provided at intervals on the sidewalls of the first extension 101 and the second extension 102. Limiting holes are provided on the first extension section 201, the second extension section 202, the first connecting seat 501, and the second connecting seat 502. Each limiting buckle can move with the first extension 101 and the second extension 102 within the first through hole 203, the second through hole 204, the first through hole, or the second through hole 503, and can be pulled out from the limiting hole to achieve limiting.

[0086] For example, such as Figures 1 to 4 As shown, in the chassis structure of this work machinery, the edges of the main frame 100 form a pair of first extensions 101 and a pair of second extensions 102 extending in opposite directions. The traveling mechanism includes a first traveling mechanism 301 and a second traveling mechanism 302.

One end of the first telescopic mechanism is detachably connected to the main frame 100, and the other end is detachably connected to the first traveling mechanism 301. The first traveling mechanism 301 is arranged laterally relative to the first extension 101.

One end of the second telescopic mechanism is detachably connected to the main frame 100, and the other end is connected to the second traveling mechanism 302.
