DETAILED DESCRIPTION

[0024] 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.

[0025] 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.

[0026] In a preferred embodiment of the present invention, a track changing system for a plank road laying machine suitable for different track gauges is provided, and its main components include a plank road laying machine chassis 1, a drive system 2, a transition assembly 3, a side guide assembly 4, a hydraulic system 5 and a leg cross beam 6. The track changing system of the present invention widens the width of the walking wheel surface by arranging multiple walking wheels side by side, so that the applicable range of the plank road laying machine is increased to match the track spacing changes that may occur during the project construction process. In addition, the present invention can achieve the purpose of adapting to different track gauges by adjusting the connection hole position by arranging guide wheels and connecting them to the chassis through a transition assembly. On the other hand, the present invention optimizes the original point-type support legs into beam-type legs, so that they can be used for tracks of different track gauges.

[0027] It should be noted that the utility model mainly relates to a track changing system below the chassis of a 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 without any limitation thereto.

[0028] The assembly relationship and the cooperation relationship between the various components are described in detail below.

[0029] The drive system 2 is installed below the chassis 1 of the plank road laying machine and is used as a power source for the plank road laying machine to travel on the track 7. The installation and fixing form between the drive system 2 and the chassis 1 of the plank road laying machine is not limited, and bolt connection can be adopted in the embodiment of the utility model. The form of the drive system 2 is not limited, and it is based on being able to drive the plank road laying machine to travel, and can be implemented by a vehicle power system in the prior art.

[0030] In the above-mentioned drive system 2, similar to the traditional vehicle power system, its driving force ultimately acts on the axle and the running wheel 2-1. However, in the utility model, each end of each axle is coaxially mounted with multiple running wheels 2-1 arranged side by side. The multiple running wheels 2-1 are arranged side by side and closely, which can flexibly expand the wheel surface width of the running wheel 2-1, thereby adapting to different track gauges. In the above-mentioned drive system 2, the number of axles is theoretically at least two, and can also be more than one. In an embodiment of the utility model, two axles can be provided, and the number of running wheels 2-1 installed at each end of a single axle is two. In common scenarios of plank road laying machines, the common track spacing is 1.5~1.9m. Therefore, in an embodiment of the present utility model, the single wheel width of the traveling wheel 2-1 can be set to 250mm, and the wheel margins at the left and right ends of each wheel axle (that is, the maximum spacing between the outer sides of the left and right traveling wheels) is 2205mm, so that the drive system 2 can adapt to different track spacings between 1.5~1.9m, greatly improving the applicability of the plank road laying machine in construction sites with different track gauges.

[0031] In addition, the function of the transition assembly 3 and the side guide assembly 4 is to provide side guidance for the plank road laying machine. A set of track change guide mechanisms is installed on the chassis 1 of the plank road laying machine corresponding to each wheel axle. Each set of track change guide mechanisms includes two sets of transition assemblies 3 and side guide assemblies 4 installed in pairs, that is, a total of two transition assemblies 3 and two side guide assemblies 4. The two transition assemblies 3 are respectively installed on both sides of the chassis 1 of the plank road laying machine, and a side guide assembly 4 is installed under each transition assembly 3. In an embodiment of the utility model, the transition assembly 3 can be implemented by a steel member, and its shape is not limited, but it should have a mounting surface that can fit the chassis 1 of the plank road laying machine, and the installation site of the side guide assembly 4 should also be provided. In order to ensure the strength of the connection position of the transition assembly 3, the position where the transition assembly 3 is connected to the side guide assembly 4 can also be additionally provided with a stiffening rib plate for structural reinforcement.

[0032] Each side guide assembly 4 used in the present invention includes a side wheel frame 4-1 and a guide wheel 4-2, the top of the side wheel frame 4-1 is fixed on the transition assembly 3, and the guide wheel 4-2 is horizontally installed on the side wheel frame 4-1 close to the track 7. In an embodiment of the present invention, the side wheel frame 4-1 is implemented by an L-shaped steel member, the top of the vertical section of which is connected to the bottom mounting surface of the transition assembly 3, and the horizontal section is used to install the guide wheel 4-2. The wheel axle of the guide wheel 4-2 is installed vertically, so that the guide wheel 4-2 is arranged horizontally as a whole, and its wheel surface can roll against the side of the track 7. The two sides of the entire plank road laying machine chassis 1 can be guided and slid along the track 7 by four guide wheels 4-2 to prevent the overall rollover or slipping out of the track.

[0033] In addition, in the embodiment of the utility model, the track 7 can be laid by using an H-shaped steel beam, and two tracks 7 can be laid side by side in the forest according to the required track gauge before construction, as the basis for the sliding of the plank road laying machine. Therefore, the wheel surface of the guide wheel 4-2 can also fit the side of the web of the H-shaped steel beam.

[0034] Since the plank road laying machine of the utility model needs to adapt to construction scenarios with different track spacings, each set of track change guide mechanisms should ensure that the spacing between the guide wheels 4-2 on both sides can be adjusted by changing the relative installation positions between the plank road laying machine chassis 1, the transition assembly 3 and the side wheel frame 4-1. It should be noted that the relative installation position adjustment here can be achieved by changing the installation spacing of the left and right transition assemblies 3 on the plank road laying machine chassis 1, or by changing the installation spacing of the side wheel frames 4-1 on both sides on the transition assembly 3, and theoretically both can achieve the corresponding functions.

[0035] In the embodiment of the utility model, the need to adjust the spacing between the guide wheels 4-2 on both sides is achieved by changing the installation spacing of the side wheel frames 4-1 on both sides on the transition assembly 3. Specifically, a plurality of different bolt holes 3-1 are opened on the transition assembly 3, and the side wheel frames 4-1 cooperate with the bolt holes 3-1 through bolts, so that the spacing between the guide wheels 4-2 on both sides can be adjusted by changing the fixed bolt holes 3-1, so as to adapt to different track gauges.

[0036] The hydraulic system 5 is installed on the chassis 1 of the plank road laying machine. The hydraulic system 5 can adopt any hydraulic drive mechanism in the prior art, such as a hydraulic drive rod, as long as it can output the displacement of up and down lifting. The installation form between the hydraulic system 5 and the chassis 1 of the plank road laying machine is not limited. In the embodiment of the utility model, the hydraulic system 5 can be connected to the chassis 1 of the plank road laying machine by bolts to facilitate disassembly and maintenance. In addition, the function of the hydraulic system 5 is to drive the two leg beams 6 for positioning and supporting on the track 7. The two leg beams 6 are respectively arranged horizontally below the laying machine chassis 1, one of which is located at the front end of the plank road laying machine along the travel direction, and the other leg beam 6 is located at the rear end of the plank road laying machine along the travel direction. The two leg beams 6 are independently driven by the hydraulic system 5 to lift and lower, and the lifting range of the two leg beams 6 should ensure that they can switch between the supporting state and the suspended state on the track 7.

[0037] In the embodiment of the utility model, in order to better realize the switching between the supporting state and the suspended state of the leg beam 6, the leg beam 6 is optimized and 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 middle. Under the design of this three-section structure, when the two side beam sections are supported on the top surface of the two side tracks 7 respectively, the protruding portion of the middle beam section extends downward into the space between the two side tracks 7, thereby preventing the leg beam 6 from slipping in the direction perpendicular to the track 7, thereby improving the safety of the plank road laying machine. In order to ensure that the track change system can cover the track gauge range of 1.5~1.9m, the length of the two side beam sections also needs to be reasonably optimized to ensure that the leg beam 6 will not interfere with the track 7 during the up and down lifting process, which will cause it to fail to work. Therefore, the form of the leg beam 6 can ensure that the length of the thinner position at the two ends covers the track gauge of 1.5~1.9m, and the thickened position in the middle can ensure the accuracy of the leg support position and realize the anti-slip function.

[0038] It should also be noted that the number of hydraulic systems 5 can be adjusted as needed, as long as it can meet the lifting and lowering drive of the two leg beams 6. In the embodiment of the utility model, if a hydraulic system 5 in the form of a hydraulic rod or the like is used, since the ends of the two leg beams 6 need to achieve synchronous lifting control, four hydraulic systems 5 can be set, and the two ends of each leg beam 6 are respectively lifted and lowered by a hydraulic system 5. Of course, in other embodiments, if a set of hydraulic systems 5 has multiple displacement output ends, it is not necessary to set four independent hydraulic systems 5.

[0039] In actual construction, after the variable pitch system of the plank road laying machine is assembled, the side guide assembly (4) can be moved to the track (7) by hoisting without installing the side guide assembly (4), and then the side guide assembly (4) can be installed, so that the chassis of the plank road laying machine can be fixed on the track. If the track spacing at some special positions changes, the guide wheel can be adjusted according to the track spacing to adapt to the track, without the need to return the entire equipment to the factory for adjustment.

[0040] In summary, the utility model increases the number of running wheels 2-1 to increase the area of ​​the running wheels, and can adapt to tracks of different track gauges without changing the drive system. In addition, the guide wheels can be adapted to different track gauges by adjusting the connection hole positions of the guide wheels. At the same time, the outriggers are improved by using a special shape of the outrigger crossbeam, so that tracks of different spacings can be adapted without replacing the crossbeam. The track changing system can be used to replace the traditional chassis of various plank road laying machines, so that the plank road laying machines have higher track gauge adjustable performance.

[0041] The embodiment described above 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. For example, in addition to bolt connection between various components, pins or other connection methods that are easy to disassemble can also be used. In addition to using bolt holes 3-1 at different positions to adjust the spacing between guide wheels, the transition component 3 can also use other connection methods such as oblong holes that are easy to adjust. In addition to using two side-by-side walking wheels to increase the width of the walking wheel surface, the drive system 2 can also use crawlers, a single large walking wheel, etc. to increase the wheel surface width. Therefore, all technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
