Detailed Description

The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It is to be understood that the description herein is only intended to illustrate and explain embodiments of the present invention, and is not intended to limit embodiments of the present invention.

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

In the embodiments of the present invention, unless otherwise specified, the use of directional terms such as "upper, lower, top, bottom" and "upper" are generally used with respect to the orientation shown in the drawings or the positional relationship of the components with respect to each other in the vertical, vertical or gravitational direction.

The invention will be described in detail below with reference to the accompanying drawings in conjunction with exemplary embodiments.

As shown in fig. 1 to 4, a first exemplary embodiment of the present invention provides a modularized chassis, which can be applied to different types of walking mechanical devices with walking function, such as rescue mechanical devices, engineering mechanical devices, etc. with walking function, and has the advantages of flexibility and strong versatility.

The modular chassis mainly comprises a chassis support structure 1 and a chassis base structure 2, wherein the chassis support structure 1 is used for supporting a functional operation structure (such as a cab and the like) in the walking mechanical equipment, and the chassis base structure 2 is used for fixing the chassis support structure 1. To ensure the operational reliability of the equipment, the high level bearing capacity of the modular chassis is not left, and under the condition that the chassis supporting structure 1 and the chassis base structure 2 can be disassembled for transportation, the specific assembling mode of how to set the chassis supporting structure and the chassis base structure needs to be considered in a focused manner, so that the adverse effect of the chassis modular design on the chassis bearing capacity is reduced as much as possible. However, at present, most of the known chassis with the modular design feature cannot well take the load-bearing capacity of the chassis into consideration, and for this reason, by setting the modular chassis of the present exemplary embodiment to have a completely new form and assembly manner, the problem of the load-bearing capacity reduction of the existing modular chassis can be effectively overcome, and related contents will be described in detail below.

Specifically, the chassis supporting structure 1 is arranged to extend vertically, and the shape and structure thereof are not limited, and can be designed and adjusted according to the specific shape and structure of the functional operation structure. The chassis base structure 2 comprises a plurality of base splicing pieces 21, the two or more base splicing pieces 21 are all available, and the plurality of base splicing pieces 21 are sequentially detachably spliced around the circumferential wall of the supporting structure of the chassis supporting structure 1 and jointly surround to define a base sleeving cavity.

In the modular chassis formed by assembling, the base splicing pieces 21 are spliced in the above manner and fixed by the self structures of the base splicing pieces 21 and/or other detachable connecting pieces additionally arranged, the chassis supporting structure 1 is detachably sleeved in the base sleeving cavity, and the self structures of the chassis supporting structure 1 and the self structures of the base splicing pieces 21 are respectively matched and/or other detachable connecting pieces additionally arranged are fixed with the chassis base structure 2.

When the modular chassis needs to be disassembled, the detachable connecting structures arranged among the module parts are disassembled to release the fixed state, so that the modular chassis can be disassembled into the chassis supporting structure 1 and the plurality of base splicing pieces 21 at least. Therefore, the modularized chassis is disassembled into a plurality of parts with small volume and light weight, and can be conveniently reassembled after being transported.

Therefore, each module part of the modular chassis has the characteristic of light weight, the transferring difficulty can be greatly reduced, and the transferring efficiency can be obviously improved. The matching mode of the chassis supporting structure 1 and the plurality of base splicing pieces 21 is beneficial to reducing the number of connecting pieces arranged between the module parts, the dismounting process can be reduced, and the dismounting efficiency is obviously improved. Under the condition that the disassembly, assembly and transfer efficiency are obviously improved, great contribution can be provided for rescue activities needing to be carried out in seconds, or the preparation time of some engineering mechanical equipment before operation can be shortened. In addition, mechanical property tests prove that the chassis assembly mode of the exemplary embodiment can still ensure that the whole bearing capacity of the chassis is kept at a higher level, and does not cause adverse effects on the whole working performance and safety performance of the chassis, so that the chassis assembly mode has a wide application prospect.

The specific mechanical property test data are as follows:

the mechanical property test mainly tests the stress condition of the modular chassis under three limit working conditions of front supporting ground, rear supporting ground and left supporting ground. As can be seen from the above table, the maximum stress of the modular chassis under the three limit conditions is less than the design target stress threshold, so that the modular chassis meets the performance requirements.

In an alternative or preferred embodiment, the modular chassis further comprises a plurality of bridging fixing structures, and any two adjacent base splices 21 are detachably connected across the fixing structures by the bridging fixing structures. In other words, in the present embodiment, the fixing of any two adjacent base splices 21 is realized by the additionally provided detachable bridging fixing structure. When the chassis base structure 2 is disassembled, a plurality of bridging fixing structures need to be disassembled first, and then the plurality of spliced base splicing pieces 21 can be disassembled.

Referring to fig. 1 and 2, the bridging fixing structure may include a bridging plate 3 and a plurality of through fixing members, the bridging plate 3 spans and overlaps two adjacent base splices 21 on two splice end walls located on the same vertical side, and the bridging plate 3 and the overlapped splice end walls are detachably through-fixed in the vertical direction by the through fixing members. For example, the bridging plate 3 is formed with a plurality of bridging plate fixing holes that run through vertically, a plurality of end wall fixing holes that run through vertically are formed on two splicing member end walls overlapped by the bridging plate 3, the plurality of bridging plate fixing holes and the plurality of end wall fixing holes are arranged along vertical one-to-one alignment, the penetrating fixing member may be a bolt or a screw, etc., and it is through penetrating corresponding bridging plate fixing holes and end wall fixing holes that run through vertically to realize the fixed connection of two adjacent base splicing members 21 and bridging plate 3.

In an alternative or preferred embodiment, the modular chassis comprises a vertical limiting structure for limiting the vertical relative displacement of the chassis supporting structure 1 and the chassis base structure 2, which can enhance the sleeving firmness of the chassis supporting structure 1 and the chassis base structure 2 sleeved with each other, and prevent the chassis supporting structure 1 and the chassis base structure 2 from vertically shaking due to strong shock generated in the operation process of the walking mechanical equipment. Of course, to ensure that the chassis support structure 1 and the chassis base structure 2 can be detached, the vertical stop structure should also be detachable from the modular chassis. It should be noted that the vertical limiting structure may be configured to be processed and produced independently of the chassis supporting structure 1 and the chassis base structure 2, or may be configured to be a self-structure of the chassis supporting structure 1 and the chassis base structure 2.

For example, the vertical restraining structure may be a restraining clip 4 that is manufactured separately from the chassis support structure 1 and the chassis base structure 2. At this moment, the supporting structure peripheral wall of chassis supporting structure 1 is formed with two peripheral wall convex parts 12 (for example, annular upper annular convex part 13 and lower annular convex part 14) arranged along vertical interval, chassis base structure 2 cup joints between two peripheral wall convex parts 12, the ground mat can be dismantled to spacing clamp 4 and establish between peripheral wall convex part 12 and chassis base structure 2 and overlap in chassis supporting structure 1, thereby press from both sides chassis supporting structure 1 and chassis base structure 2 along vertical clamp, avoid chassis supporting structure 1 and chassis base structure 2 to rock along vertical in the operation process because of there being vertical fit clearance. From another angle, under the condition that sets up spacing clamp 4, must keep certain vertical fit clearance between chassis bearing structure 1 and the chassis base structure 2, the dismouting degree of difficulty that the existence in fit clearance can reduce chassis bearing structure 1 and chassis base structure 2 reduces the two direct contact wearing and tearing, both improves dismouting efficiency, can delay wearing and tearing again.

The stopper clips 4 may be provided only between the peripheral wall protrusion 12 located above and the upper end wall of the chassis base structure 2, only between the peripheral wall protrusion 12 located below and the lower end wall of the chassis base structure 2, or both.

Further, in order to facilitate the detachment and installation of the limit clamp 4, the limit clamp 4 may be configured to be sequentially detachably spliced around the circumferential wall of the support structure by a plurality of clamp splicing sections 41, for example, by two or more clamp splicing sections 41. When two adjacent band splicing sections 41 are spliced, the band splicing sections 41 can be fixed by the self-structure of the band splicing sections 41 and/or other detachable connecting pieces additionally arranged.

In an alternative or preferred embodiment, the modular chassis comprises a circumferential limiting structure for limiting relative displacement of the chassis support structure 1 and the chassis base structure 2 sleeved with each other along the circumferential direction, so that it can be ensured that the chassis support structure 1 and the chassis base structure 2 do not generate relative displacement along the circumferential direction, or only allow relative displacement along the circumferential direction within a short range, so as to further enhance the sleeving stability of the chassis support structure 1 and the chassis base structure 2.

Especially for a special modular chassis for rotary mechanical equipment, the arrangement of the circumferential limit structure is more important. Since in a swing type machine, the functional work structure thereof is rotatable in the circumferential direction with respect to the modular chassis, when the functional work structure is rotated for work, the risk of displacement of the chassis support structure 1 as a whole in the circumferential direction with respect to the chassis base structure 2 is greater, and the instability of the work of the machine is higher. For this reason, in the modular chassis dedicated to the rotary type mechanical apparatus, the circumferential direction restricting structure should be further formed as a circumferential direction fixing structure, ensuring that the chassis support structure 1 and the chassis base structure 2 are always kept fixed to each other in the circumferential direction in the assembled state, and even in the case where relative displacement in the circumferential direction is generated in a short range, it should be avoided.

The following description will be made by exemplifying specific arrangements of the circumferential direction limiting structure in the modular chassis having a certain versatility and the circumferential direction fixing structure in the modular chassis dedicated to the rotary type mechanical apparatus.

Firstly, in a modular chassis with a certain versatility, the circumferential stop structure may comprise a positioning pin 5. At this time, the circumferential wall protrusion 12 of the chassis supporting structure 1 is formed with a protrusion positioning hole that penetrates vertically (for example, the upper annular protrusion 13 is formed with a plurality of protrusion positioning holes that are sequentially arranged at intervals along the circumferential direction), the chassis base structure 2 is formed with an end wall positioning hole along the vertical end wall (for example, the upper end wall of each base splice 21 is formed with at least one end wall positioning hole that penetrates vertically), the protrusion positioning hole and the end wall positioning hole are arranged along the vertical alignment, the protrusion positioning hole and the end wall positioning hole are detachably connected through the positioning pin 5, and the chassis supporting structure 1 and the chassis base structure 2 can be fixed to each other along the circumferential direction. When a plurality of boss positioning holes and a plurality of end wall positioning holes are vertically arranged in one-to-one alignment, a corresponding number of positioning pins 5 should be provided.

Further, when being equipped with aforementioned spacing clamp 4 (especially the spacing clamp 4 that forms through the concatenation of a plurality of clamp splice sections 41), also can utilize locating pin 5 to wear to connect fixed spacing clamp 4 to simplify the dismouting mode on modularization chassis, improve dismouting efficiency. Specifically, the limiting clamp 4 may be formed with a clamp positioning hole that runs through vertically, and at this time, the boss positioning hole, the clamp positioning hole, and the end wall positioning hole are arranged along vertical alignment, detachably passing the boss positioning hole, the clamp positioning hole, and the end wall positioning hole through the positioning pin shaft 5, and the chassis support structure 1, the chassis base structure 2, and the limiting clamp 4 may be fixed simultaneously in the circumferential direction. Similarly, when there are a plurality of boss locating holes and a plurality of end wall locating holes arranged in a vertical, one-to-one alignment, there should also be a corresponding number of collar locating holes.

In a modular chassis dedicated to rotary mechanical equipment, the chassis support structure 1 may be a rotary bearing 11, and the rotary bearing 11 includes an outer bearing sleeve and an inner bearing sleeve which is sleeved on the outer bearing sleeve and can perform rotary motion in the outer bearing sleeve. At this time, the plurality of base splicing members 21 are detachably spliced in a closed loop along the horizontal direction and jointly encircle to define the base sleeving cavity, the supporting outer sleeve is detachably sleeved in the base sleeving cavity, and the supporting inner sleeve is used for being fixed with a functional operation structure in the rotary mechanical equipment so as to synchronously rotate along with the functional operation structure. In addition, a circumferential securing structure is used to secure the support outer sleeve and the plurality of base splices 21 to each other in the circumferential direction of the support outer sleeve.

When the outer sleeve peripheral wall bearing the outer sleeve is provided with the aforementioned two peripheral wall protrusions 12, the aforementioned peripheral fixing manner in the embodiment of circumferentially fixing the chassis support structure 1 and the chassis base structure 2, or circumferentially fixing the chassis support structure 1, the chassis base structure 2 and the limit clip 4 by the positioning pin 5 is also applicable to the modular chassis dedicated to the rotary type mechanical apparatus, and therefore, the description will not be repeated here.

It is additionally stated that in a modular chassis intended for rotary-type machines, the limit clip 4 is, when the aforementioned limit clip 4 is provided, sleeved on the peripheral wall of the outer sleeve supporting the outer sleeve. Further, when the limit clip 4 is formed by splicing a plurality of clip splicing sections 41, the plurality of clip splicing sections 41 are sequentially detachably spliced around the outer sleeve peripheral wall.

In an alternative or preferred embodiment, the chassis base structure 2 is formed with a pin stopping structure located axially inward of the end wall positioning hole, and during the process of inserting the positioning pin 5, when the axially inner end of the positioning pin 5 is inserted to abut against the pin stopping structure, the positioning pin is known to be inserted in place, and the installation personnel can be reminded. For example, the pin stopping structure may be a splice stopping rib 23 formed inside the base splice 21, and after the insertion of the positioning pin 5 is completed, the axial lower end of the positioning pin 5 abuts against the corresponding splice stopping rib 23.

In an alternative or preferred embodiment, only one limit clip 4 is provided in the modular chassis, which further simplifies the assembly and disassembly process. Specifically, the lower end wall of the chassis base structure 2 abuts against the circumferential wall protrusion 12 located below (for example, the lower end wall of each base splicing member 21 abuts against the lower annular protrusion 14), and the limiting clamp 4 is disposed between the upper end wall of the chassis base structure 2 and the circumferential wall protrusion 12 located above (for example, the upper annular protrusion 13 and the upper end wall of each base splicing member 21 are vertically spaced apart, and the limiting clamp 4 is disposed in the matching gap above).

In order to enhance the connection stability between the lower end wall of the chassis base structure 2 and the peripheral wall protrusion 12 located below, a protrusion clamping groove with an upward notch may be formed in the peripheral wall protrusion 12 located below, and meanwhile, the lower end wall of the chassis base structure 2 is formed with a base clamping portion 22 matched with the protrusion clamping groove at a position close to the base socket cavity (for example, the lower end wall of each base splice 21 is formed with the base clamping portion 22 at a position close to the base socket cavity). Through the mutual buckle of bellying joint groove and base joint portion 22, can prevent effectively that chassis base structure 2's lower part from along transversely deviating chassis bearing structure 1.

Further, from the viewpoint of facilitating the mounting and dismounting, a guide mounting and dismounting structure may be formed at the fitting structure of the boss catching groove and the base catching portion 22. Specifically, the outer side surface of the boss catching groove may be disposed to be inclined outward with respect to the bottom surface, and the outline of the base catching portion 22 is correspondingly disposed to be matched with the outline of the boss catching groove. So set up, no matter be in the equipment or dismantle the in-process, the slope lateral surface in bellying joint groove can both play the guide effect, is favorable to reducing the dismouting degree of difficulty, improves dismouting efficiency.

By way of example, referring to fig. 3, the boss catching groove is provided as a wedge-shaped groove, an inner side surface of the wedge-shaped groove is formed as a vertical surface of the wedge-shaped groove, and an outer side surface thereof is formed as an inclined surface of the wedge-shaped groove, and the base catching portion 22 is correspondingly provided to have a wedge shape matching the wedge-shaped groove, that is, an outer wall surface of the base catching portion 22 is in abutting contact with an inner wall surface of the wedge-shaped groove. When the chassis supporting structure 1 and the chassis base structure 2 are disassembled and assembled, the inclined surface of the wedge-shaped groove plays a role in guiding disassembly and assembly.

In an optional or preferred embodiment, for taking into account factors such as lightweight transportation and dismouting efficiency simultaneously, the base splicer 21 quantity in the modularization chassis only sets up two, and these two base splicers 21 form respectively into the base left side splice and the base right side splice of splicing along the left and right sides direction of modularization chassis. So set up, not only can reduce the quantity of adapting unit such as base splice 21 and bridging fixed knot structure, still can directly form stable in structure, the strong left side walking connecting portion of bearing capacity and right side walking connecting portion respectively on base left side splice and base right side splice to left side running gear and the right side running gear (for example wheel, track etc.) that are arranged in connecting the walking mechanical equipment and carry out the drive walking function.

A second exemplary embodiment of the present invention provides a walking machine, which includes the above-mentioned modular chassis, for example, the modular chassis may be a modular chassis with a strong versatility, or a modular chassis dedicated to a rotary machine, or the like. Obviously, the walking mechanism device of the present exemplary embodiment has all the technical effects brought by the above-mentioned modular chassis, and therefore, the detailed description thereof is omitted here.
