DETAILED DESCRIPTION

[0029] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed below. The technical features in each embodiment of the utility model can be combined accordingly without conflicting with each other.

[0030] In the description of the present utility model, it is necessary to understand that when an element is considered to be "connected" to another element, it can be directly connected to another element or indirectly connected, that is, there are intermediate elements. On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0031] like Figure 1 As shown, in a preferred embodiment of the utility model, a plank road laying machine slope adaptation system is provided, which can be installed at the bottom of the plank road laying machine with an I-beam track as the driving track 1. On the one hand, it can improve the climbing ability of the plank road laying machine during the walking process, and on the other hand, it can achieve leveling on the slope driving track, so that the working state can adapt to a larger slope. The components of the plank road laying machine slope adaptation system include a chassis assembly 2, a running wheel 3, a guide wheel assembly 4, and a dual-motor four-wheel drive system. The specific structure and assembly working method of each component are described in detail below.

[0032] like Figure 2 As shown, in the slope adaptation system of the plank road laying machine of the utility model, the chassis assembly 2 is the main part, and the remaining components can be installed on the chassis assembly 2. The chassis assembly 2 includes a chassis assembly weldment 21, a slewing bearing connector 22, a front support leg 23, a rear support leg 24, a front support leg cross beam 25 and a rear support leg cross beam 26.

[0033] It should be noted that the utility model mainly relates to the slope adaptation system below the chassis of the plank road laying machine. The upper structure of the plank road laying machine is not limited and can be designed with reference to the plank road laying machine in the prior art, and no limitation is imposed on this. Other structures of the plank road laying machine above the chassis, such as a hoisting mechanism, a balancing weight, a cockpit, etc., can be installed on the chassis assembly weldment 21. In an embodiment of the utility model, the chassis assembly weldment 21 is a steel mounting frame, which is welded by steel beams, steel plates or other steel materials. A slewing bearing connector 22 can be provided on the top of the chassis assembly weldment 21, and other structures of the plank road laying machine are assembled through the slewing bearing connector 22. The specific form of the slewing bearing connector 22 can refer to the mechanical structure of a traditional plank road laying machine.

[0034] Two front and rear axles are installed at the bottom of the chassis assembly weldment 21, and the two ends of each axle are respectively equipped with running wheels 3. The running wheels 3 are the wheels required for the entire plank road laying machine to move. The running wheels 3 installed at a single end of each axle can be one or more. In theory, a single running wheel 3 can realize the movement of the plank road laying machine. However, if the need to adapt to different track gauges of running tracks 1 is taken into consideration, it is also possible to consider arranging two or more running wheels 3 coaxially assembled side by side at a single end of each axle, thereby expanding the width of the wheel surface. In addition, in the utility model, in order to increase the friction between the steel wheel and the track as much as possible, the running wheels 3 can be steel wheels, and rubber with anti-skid patterns can be applied on the outside. In addition, the running wheels 3 on the front and rear axles are driven to rotate by a dual-motor four-wheel drive system, and the running wheels 3 installed at both ends of each axle can roll along the upper flanges of two parallel I-beam tracks. Therefore, the friction between the walking wheel 3 and the track is improved by improving the wheel body form of steel wheel + rubber. At the same time, by adopting a dual drive motor, that is, a four-wheel drive drive mode, the plank road laying machine can greatly improve its climbing ability during walking after installing the slope adaptation system, so that the walking state can adapt to a larger slope.

[0035] It should be noted that the dual-motor four-wheel drive system used in the present invention has a variety of achievable forms in the prior art, and in theory any prior art solution can be used. In an embodiment of the present invention, the dual-motor four-wheel drive system includes an electric vehicle drive axle assembly 5 and a drive motor 6. The electric vehicle drive axle assembly 5 is provided with two front and rear ones, each of which is equipped with an independent drive motor 6 to realize dual-motor four-wheel drive of the front and rear walking wheels 3. The power supply of the drive motor 6 can come from its own battery, or it can be supplied by other mains electricity or power generation equipment, and there is no restriction on this. However, considering the special environment of plank road paving operations in the mountains and forests, it is preferred to consider using batteries to provide power.

[0036] In addition, in addition to the improvement of the running wheel 3, the present invention also optimizes the chassis assembly 2 and the guide wheel assembly 4, so that the plank road laying machine can be self-leveled on a driving track with a slope, so that the working state can adapt to a larger slope. Specifically, there are four groups of guide wheel assemblies 4, wherein a group of guide wheel assemblies 4 are respectively installed on both sides of the chassis assembly 2 where the front wheel axle and the rear wheel axle are located. Among them, the two groups of guide wheel assemblies 4 installed on both sides of the chassis assembly 2 where the front wheel axle is located are used to guide the position of the front wheel, and the two groups of guide wheel assemblies 4 installed on both sides of the chassis assembly 2 where the rear wheel axle is located are used to guide the position of the rear wheel. Each group of guide wheel assemblies 4 includes a side wheel frame 41 and a guide wheel 42, the side wheel frame 41 is installed on the chassis assembly 2, and the guide wheel 42 is horizontally installed on the side wheel frame 41. From the side view direction, the side wheel frame 41 in the embodiment of the present utility model is located in front of the center of the running wheel 3. Moreover, the guide wheel 42 needs to be installed on the side wheel frame 41 on the side of the I-beam track on which the plank road laying machine travels, so that the wheel surface of the guide wheel 26 can roll against the side of the I-beam track to form a guiding effect. Since the I-beam track in the utility model has upper and lower flange plates and a web plate, the guide wheels 42 corresponding to the two sides of each wheel axle will respectively roll against the outer walls of the web plates of the two parallel I-beam tracks during actual operation.

[0037] In addition, considering that the plank road laying machine has a large deadweight, it is difficult for it to rely on its own braking to stop on a track with a large slope. Therefore, in the chassis assembly 2 of the utility model, two groups of support leg beams are set under the chassis assembly weldment 21 to switch different working states. The specific implementation mechanism includes a front support leg 23, a rear support leg 24, a front support leg beam 25 and a rear support leg beam 26. Specifically, the front support leg beam 25 is horizontally arranged at the front end of the front wheel axle and the two ends of the beam are lifted and lowered by a pair of front support legs 23, while the rear support leg beam 26 is horizontally arranged at the rear end of the rear wheel axle and the two ends of the beam are lifted and lowered by a pair of rear support leg beams 26. It should be noted that the front end and the rear end here are described relative to the travel direction of the plank road laying machine. In the overall layout, the two wheel axles are located in the area between the front support leg beam 25 and the rear support leg beam 26.

[0038] It should be noted that the front support leg 23 and the rear support leg 24 can theoretically control the lifting and lowering of the front and rear support leg beams, and any existing technical solution can be used. In the embodiment of the utility model, the front support leg 23 and the rear support leg 24 both use hydraulically driven jacking mechanisms, and there are four jacking mechanisms in total. The output displacement push rods in the two jacking mechanisms are respectively connected to the two ends of the front support leg beam 25, and the output displacement push rods in the other two jacking mechanisms are respectively connected to the two ends of the rear support leg beam 26. The main bodies of the four jacking mechanisms can be installed on the chassis assembly weldment 21. Of course, it can be understood that in addition to the jacking mechanism, the entire system should also be equipped with hydraulic pipelines, control circuits, etc. required for cooperating with the hydraulic drive. These belong to the existing technology and will not be repeated.

[0039] In the embodiment of the utility model, in actual work, the front support leg 23 is arranged on the front side of the front bogie of the plank road laying machine, and the rear support leg 24 is arranged on the rear side of the rear bogie of the plank road laying machine. The front support leg 23 and the rear support leg 24 are controlled by hydraulic pipelines so that their top rods are suspended downward, which are used for parking the plank road laying machine in the working state and leveling the plank road laying machine after parking. The front support leg crossbeam 25 and the rear support leg crossbeam 26 are respectively arranged under the top rods of the front support leg 23 and the rear support leg 24, and are connected to the top rods, so that the support leg crossbeams can realize multi-gauge parking when the support legs are parked. With the cooperation of the front support leg 23 and the rear support leg 24, the plank road laying machine equipped with the slope adaptation system of the utility model can switch between the walking state and the parked working state:

[0040] like Figure 3 As shown, when in the walking state, it adopts dual-motor four-wheel drive, steel wheels coated with rubber, and anti-skid patterns to improve climbing ability and adapt to the slope changes during plank road construction;

[0041] And as Figure 4 As shown, in the parked working state, the plank road laying machine needs to be in a horizontal state, that is, the running wheels are suspended in the air and parked and leveled by the supporting legs.

[0042] In addition, since the top rods of the front and rear support legs are suspended downward for leveling, there is a height difference between the front and rear running wheels, the guide wheels and the top surface of the track. It is necessary to design the height difference between the guide wheels and the bottom surface of the running wheels, the height of the web of the running track, etc. The calculation diagram of the slope adaptation system of the plank road laying machine is as follows: Figure 5 As shown, the center line of the running wheel and the rear edge line of the guide wheel are set to coincide with each other in the vertical projection plane during design. The size parameters of the components in the total chassis assembly 2, the running wheel 3 and the guide wheel assembly 4 of the slope adaptation system need to meet the following three constraints:

[0043] L2≥L1×i

[0044] H>(L3+d×i)cosα

[0045] H>L3

[0046] Wherein, i=tanα, L3=L2+h, i is the slope of the track, α is the slope angle of the track, L1 is the center distance between the front and rear wheel axles, H is the web height of the I-beam track, L2 is the vertical distance from the upper surface of the guide wheel 42 to the bottom surface of the running wheel 3, L3 is the vertical distance from the lower surface of the guide wheel 42 to the bottom surface of the running wheel 3, and h is the thickness of the guide wheel 42.

[0047] In order to better understand the technical effect that can be achieved by the above parameter design of the present invention, the following is demonstrated by a specific example calculation. In this example, L1=1900mm, h=60mm, d=340mm, L2=153mm, L3=213mm are used, and the minimum value of H is calculated to be 240mm, so the driving track selected in the example is H300×200×14×14 steel beam. Finally, the slope adaptation system of the plank road laying machine in this example can adapt to the design slope of 0-8%. In actual work, the plank road laying machine can move forward and climb the slope by starting the drive motor; after the plank road laying machine arrives at the work site, press the parking button to brake; start the automatic leveling button, and use the front support leg and the rear support leg top rod to lift up and level the chassis assembly, and make the walking wheel and the driving track separate in the height direction. After the leveling is completed, the support leg oil cylinder solenoid valve is closed by electrical control.

[0048] In addition, in the embodiment of the utility model, in order to better realize the switching between the supporting state and the suspended state of the two supporting leg beams, the front supporting leg beam 25 and the rear supporting leg beam 26 can be designed as a three-section structure, and the middle beam section has a protruding portion relative to the two side beam sections, and the overall shape is similar to a spindle with small ends and thick in the middle. Under the design of this three-section structure, when the two side beam sections are respectively supported on the top surface of the two side running tracks 1, the protruding portion of the middle beam section extends downward into the space between the two side running tracks 1, thereby preventing the supporting leg beams from slipping in the direction perpendicular to the running tracks 1, thereby improving the safety of the plank road laying machine. It should also be noted that the length of the two side beam sections also needs to be reasonably optimized according to the track spacing to ensure that the beams will not interfere with the tracks during the up and down lifting process, resulting in failure to work.

[0049] In addition, the connection method between the components in the utility model is theoretically not limited, as long as it can meet the corresponding strength requirements and actuation matching relationships. For example, the support leg and the support leg crossbeam can be connected by bolts or welding, the running wheel and the axle of the tram drive axle assembly can be connected by bolts, the side wheel frame and the bogie can be connected by bolts, and the guide wheel can be connected to the side wheel frame by fixing screws.

[0050] In the embodiment of the utility model, the side wheel frame 41 is an L-shaped steel member, which is welded by a vertical end and a horizontal section. The top of the vertical section is fixed to the chassis assembly weldment 21 by bolts, and the horizontal section is equipped with a guide wheel 42. In addition, the guide wheel 42 is preferably detachably connected to the side wheel frame 41 by fixing screws to facilitate maintenance and replacement. Similarly, the front support leg 23 and the front support leg cross beam 25, and the rear support leg 24 and the rear support leg cross beam 26 are preferably connected by bolts.

[0051] The above-described embodiment is only a preferred solution of the utility model, but it is not intended to limit the utility model. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
