With the increase of the mining depth and the dynamic expansion of the working face, the track network needs to be continuously extended and laid. However, when laying tracks at present, the transportation and laying of the track are usually carried out manually. Due to the large size and weight of the track, the manual operation efficiency is low. The handling of the track requires multiple workers to cooperate synchronously. Moreover, the manual handling of heavy tracks is prone to accidents such as muscle strain and slipping and bruising, which is not conducive to improving the construction efficiency of track laying.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] Embodiment 1 This embodiment relates to a track-laying device, aiming to facilitate the improvement of the track-laying efficiency by optimizing the structure of the track-laying device.

[0028] In terms of the overall structure, as Figures 1 to 6 shown, the track-laying device of this embodiment is used for laying the track of a rack rail vehicle, and includes a first flatbed truck 1 and a second flatbed truck 2 connected to the first flatbed truck 1. Loading mechanisms 3 are provided on both the first flatbed truck 1 and the second flatbed truck 2, and the loading mechanisms 3 are used for loading the track.

[0029] Among them, a rotary and luffing mechanism 4, a first telescopic mechanism 5 and a clamping mechanism 6 are provided on the first flatbed truck 1. The rotary and luffing mechanism 4 is arranged at one end of the first flatbed truck 1 away from the second flatbed truck 2 to be able to drive the first telescopic mechanism 5 to rotate and luff. The first telescopic mechanism 5 is connected between the rotary and luffing mechanism 4 and the clamping mechanism 6 to be able to drive the clamping mechanism 6 to approach or move away from the rotary and luffing mechanism 4. The clamping mechanism 6 is used for clamping the track on the loading mechanism 3.

[0030] With the above settings, in the track-laying device of this embodiment, through the settings of the first flatbed truck 1 and the second flatbed truck 2, it is convenient to move in the roadway. Through the setting of the loading mechanism 3, it is convenient to load the track. Through the cooperation of the rotary and luffing mechanism 4 and the first telescopic mechanism 5, the position of the clamping mechanism 6 can be moved. Through the setting of the clamping mechanism 6, the track can be constrained on the clamping mechanism 6. Through the cooperation of the rotary and luffing mechanism 4, the first telescopic mechanism 5 and the clamping mechanism 6, after the track is constrained on the clamping mechanism 6, it can be moved to a predetermined laying position, and after the construction personnel align it, the track can be assembled at the predetermined laying position, avoiding manual handling, improving the efficiency of track handling, and facilitating the improvement of the track-laying efficiency.

[0031] Specifically, in this embodiment, as an exemplary structure, in combination with Figures 1 to 3 shown, in order to better move the position of the clamping mechanism 6, the first telescopic mechanism 5 of the track-laying device in this embodiment includes a fixed arm 501, a telescopic arm 502 and a first telescopic unit 503.

[0032] Among them, the fixed arm 501 is arranged on the rotary and luffing mechanism 4, the telescopic arm 502 is slidably arranged on the fixed arm 501, and both ends of the first telescopic unit 503 are respectively hinged on the fixed arm 501 and the telescopic arm 502 to drive the telescopic arm 502 to approach or move away from the fixed arm 501. Through the settings of the fixed arm 501, the telescopic arm 502 and the first telescopic unit 503, the telescopic arm 502 can be driven by the first telescopic unit 503 to move away from or close to the fixed arm 501, thus facilitating the movement of the position of the clamping mechanism 6. The structure is simple and helps with the design and implementation.

[0033] It is worth mentioning that in order to better ensure the structural strength of the fixed arm 501, the telescopic arm 502 is sleeved on the end of the fixed arm 501, and the telescopic arm 502 is located in the inner layer. A reinforcing plate is provided between the fixed arm 501 and the telescopic arm 502. The reinforcing plate is arranged on the fixed arm 501 to ensure the structural strength of the fixed arm 501 when the telescopic arm 502 slides on the fixed arm 501, which is beneficial to the design and implementation. Of course, the first telescopic mechanism 5 in this embodiment can also directly adopt a boom with a multi-stage telescopic structure in the prior art, and only need to assemble the fixed end of the boom on the slewing and luffing mechanism 4.

[0034] More specifically, the first telescopic unit 503 can be, for example, a hydraulic cylinder. The cylinder block of the hydraulic cylinder is fixedly installed on the fixed arm 501, and the piston rod of the hydraulic cylinder is fixedly installed on the telescopic arm 502. In order to better protect the first telescopic unit 503, a protective frame is provided on the first telescopic unit 503. Through the setting of the protective frame, it helps to protect the first telescopic unit 503 and avoid the first telescopic unit 503 being damaged during the movement of the first telescopic mechanism 5, improving the service life of the device and being beneficial to the design and implementation.

[0035] In addition, it should be noted that in order to increase the working range of the first telescopic mechanism 5, the first telescopic unit 503 and the telescopic arm 502 can be further installed on the telescopic arm 502. By increasing the number of the telescopic arm 502 and the first telescopic unit 503, the length of the first telescopic mechanism 5 is increased, thereby increasing the working range of the first telescopic mechanism 5.

[0036] In order to better improve the working range of the track-laying device, as shown in Figures 1 to 3 the slewing and luffing mechanism 4 in this embodiment includes a slewing part 401 and a luffing part 402.

[0037] Among them, the slewing part 401 includes a support frame 4011 arranged on the first flatbed truck 1 and a slewing unit 4012 arranged on the support frame 4011. In this embodiment, the slewing unit 4012 can be, for example, a slewing bearing. The slewing bearing in this embodiment can adopt the slewing bearing commonly used by those skilled in the current technical field.

[0038] The boom section 402 includes a support column 4021 provided on the slewing unit 4012 and a pitching adjustment unit 4022 provided on the slewing unit 4012.

Through the arrangement of the slewing section 401 and the boom section 402, it is convenient to realize the slewing and pitching angle adjustment of the first telescopic mechanism 5, making the slewing section 401 include a support frame 4011 and a slewing unit 4012, facilitating the arrangement of the slewing unit 4012, and having a simple structure. The boom section 402 includes a support column 4021 and a pitching adjustment unit 4022, which improves the structural strength of the boom section 402, facilitates the adjustment of the working range of the first telescopic mechanism 5, and is beneficial for design and implementation.

[0039] For the convenience of the construction of the track-laying device, as shown in combination with Figure 1 、 Figure 3 and Figure 4 shown, a second telescopic mechanism 7 is further provided on the first flatbed truck 1 in this embodiment. The second telescopic mechanism 7 includes a fixed frame 701 and a second telescopic unit 702.

[0040] Among them, the support frame 4011 of the slewing and luffing mechanism 4 is slidably provided on the fixed frame 701. The two ends of the second telescopic unit 702 are respectively connected to the fixed frame 701 and the support frame 4011 to drive the support frame 4011 to approach or move away from the fixed frame 701. In this embodiment, the second telescopic unit 702 can be, for example, a hydraulic cylinder. In order to facilitate control, a control valve can also be provided on the hydraulic cylinder to facilitate the control of the telescopic movement of the second telescopic unit 702. Through the arrangement of the second telescopic mechanism 7, the positions of the slewing and luffing mechanism 4, the first telescopic mechanism 5, and the clamping mechanism 6 can be extended and moved outward from the side of the first flatbed truck 1, which helps to expand the movement range of the clamping mechanism 6, helps to better move the track-laying to the laying position, and is beneficial for design and implementation.

[0041] In addition, before introducing the clamping mechanism 6 in this embodiment, it is necessary to briefly introduce the structure of the track-laying. The track-laying generally includes two parallel tracks and a connecting rod provided between the two tracks, or a toothed track parallel to the two tracks is provided in the middle of the track-laying. When the clamping mechanism 6 in this embodiment clamps the track-laying, it clamps on the connecting rod or the toothed track.

[0042] Specifically, as shown in combination with Figures 1 to 3As shown in the figure, the clamping mechanism 6 in this embodiment includes a connecting plate 601, a first clamping plate 602, a second clamping plate 603, and a movable pin 604. Among them, the connecting plate 601 is rotatably arranged on the first telescopic mechanism 5. The first clamping plate 602 and the second clamping plate 603 are respectively arranged on opposite sides of the connecting plate 601. The movable pin 604 is operably inserted below the first clamping plate 602 and the second clamping plate 603 to restrain the track panel on the clamping mechanism 6. The clamping mechanism 6 includes a connecting plate 601, a first clamping plate 602, a second clamping plate 603, and a movable pin 604, with a simple structure, convenient for assembly, and helpful for design and implementation.

[0043] Among them, the space enclosed by the connecting plate 601, the first clamping plate 602, and the second clamping plate 603 is used to accommodate the connecting rod or toothed rail of the track panel. After the track panel enters this space, the movable pin 604 is inserted below the first clamping plate 602 and the second clamping plate 603. For better stable clamping, the number of movable pins 604 is two, and through holes are provided at the ends of the movable pins 604. When the movable pins 604 are inserted on the first clamping plate 602 and the second clamping plate 603, limit pins can be inserted into the through holes on the protruding ends to prevent the movable pins 604 from coming out during the lifting process.

[0044] To better ensure the use of the movable pin 604, the clamping mechanism 6 in this embodiment further includes a flexible connecting piece. One end of the flexible connecting piece is connected to the first clamping plate 602 or the second clamping plate 603, and the other end of the flexible connecting piece is connected to the movable pin 604 to restrain the movable pin 604 on the first clamping plate 602 or the second clamping plate 603. Through the setting of the flexible connecting piece, after the movable pin 604 detaches from the first clamping plate 602 and the second clamping plate 603, it helps to restrain the movable pin 604 on the clamping mechanism 6, avoid the loss of the movable pin 604, and is beneficial to design and implementation. In this embodiment, the flexible connecting piece can be, for example, a chain, a strip, etc.

[0045] In addition, to better carry the track panel, as shown in combination with Figure 1 and Figure 6 the carrying mechanism 3 in this embodiment includes multiple pairs of carrying units 301 spaced on the first flatbed truck 1 and the second flatbed truck 2. A carrying rod 302 is provided on each pair of carrying units 301. The track panel is placed on the carrying rods 302 of adjacent pairs of carrying units 301. Multiple carrying rods 302 are arranged vertically on each pair of carrying units 301. Through the carrying rods 302 arranged vertically, it is convenient for the stacked arrangement of the track panels, which is beneficial for transporting the track panels. Through the setting of the carrying rods 302 and the carrying units 301, it helps the track panels to be stacked better on the carrying mechanism 3, which is beneficial to design and implementation.

[0046] Specifically, as shown in combination with Figure 1 and Figure 5As shown in the figure, the bearing unit 301 includes a first bearing member 3011, a second bearing member 3012, and a limiting member 3013. The bottom of the first bearing member 3011 is disposed on the first flatbed truck 1 or the second flatbed truck 2, and the top of the first bearing member 3011 is hinged to the bottom of the second bearing member 3012.

[0047] Among them, a first stop groove 3014 and a second stop groove 3015 are provided on the first bearing member 3011. The second stop groove 3015 is disposed below the first stop groove 3014. The outer walls on the same side of the first bearing member 3011 and the second bearing member 3012 respectively extend outward to form a first boss 3016 and a second boss 3017. A first through hole is provided on the first boss 3016, and a second through hole is provided on the second boss 3017. When the bottom of the limiting member 3013 is located in the first stop groove 3014, the top of the limiting member 3013 passes through the first through hole and the second through hole to restrict the rotation of the second bearing member 3012 relative to the first bearing member 3011. When the bottom of the limiting member 3013 is located in the second stop groove 3015, the top of the limiting member 3013 disengages from the second through hole, and the second bearing member 3012 can rotate around the hinge joint of the second bearing member 3012 and the first bearing member 3011. Through the hinge connection between the first bearing member 3011 and the second bearing frame, it is convenient to load and unload the track panel located below the bearing mechanism 3. Through the arrangement of the limiting member 3013, the stop groove, and the through hole, it is convenient to ensure the stability of the bearing mechanism 3 during transportation, and it is convenient to operate and beneficial to the design and implementation.

[0048] The track panel laying device of this embodiment is convenient for transporting the track panel to the laying position, and through the cooperation of the rotary swing mechanism 4, the first telescopic mechanism 5, the second telescopic mechanism 7, and the clamping mechanism, the track panel is hoisted from the bearing mechanism 3 to the laying position. After being aligned by the construction personnel, the track panel is paved at the predetermined paving position, effectively improving the transportation efficiency and paving efficiency of the track panel, thereby being beneficial to improving the construction efficiency of track panel laying.

[0049] Embodiment Two This embodiment relates to a construction method of a track panel laying device, which is applied to the track panel laying device in Embodiment One. Combining Figure 6 and Figure 7 as shown in the figure, it includes the following steps: Step S1: Load the track panel on the first flatbed truck 1 and the second flatbed truck 2 and stack it on the bearing mechanism 3.

[0050] Among them, in this step S1, the track panel is directly loaded on the bearing mechanism 3 after being assembled and produced at the processing site, or after being assembled and produced at the processing site, it is placed in the storage area, and the track panel in the storage area is stacked on the bearing mechanism 3 through a hoisting device.

[0051] Step S2: Dock the track laying device at the predetermined laying position.

[0052] Among them, in this step S2, generally speaking, the predetermined laying position is the end of the track in the roadway. Usually, the first flatbed truck 1 or the second flatbed truck 2 can be driven by a power device to make the track laying device travel on the track. After the track laying device travels to the end of the track, the track laying device is docked to prepare for the laying of the track.

[0053] Step S3: Adjust the rotary luffing mechanism 4 and the first telescopic mechanism 5 to move the clamping mechanism 6 above the track to be laid and restrain the track on the clamping mechanism 6.

[0054] Among them, in this step S3, when adjusting the rotary luffing mechanism 4 and the first telescopic mechanism 5, first, the rotary luffing mechanism 4 rotates to the state where the clamping mechanism 6 faces the bearing mechanism 3, and then the first telescopic mechanism 5 extends to move the clamping mechanism 6 above the track to be laid, and the track is assembled on the clamping mechanism 6 so that the track can be restrained on the clamping mechanism 6 and thus move together with the clamping mechanism 6.

[0055] Step S4: Adjust the rotary luffing mechanism 4 and the first telescopic mechanism 5 to move the track to the predetermined laying position.

[0056] Among them, in this step S4, when adjusting the rotary luffing mechanism 4 and the first telescopic mechanism 5, first, the first telescopic mechanism 5 is retracted by a part, then the rotary luffing mechanism 4 rotates to the state where the clamping mechanism 6 faces the predetermined laying position, then the first telescopic mechanism 5 extends to move the clamping mechanism 6 above the predetermined laying position, and the rotary luffing mechanism 4 luffs to lower the clamping mechanism 6 so that the track approaches the predetermined laying position.

[0057] Step S5: Align the track to be laid with the laid track and install it at the predetermined laying position after alignment.

[0058] Among them, in this step S5, after the track moves to the predetermined laying position, the construction personnel align the track to be laid with the laid track. After the construction personnel align the track, the clamping mechanism 6 is released from the track, so as to carry out the subsequent track assembly and laying work.

[0059] Step S6: Repeat the above operations until all the tracks on the first flatbed truck 1 and the second flatbed truck 2 are laid.

[0060] Among them, in this step S6, first, the tracks on the first flatbed truck 1 are laid one by one, and then the tracks on the second flatbed truck 2 are laid until all the tracks on the first flatbed truck 1 and the second flatbed truck 2 are laid.

[0061] In addition, it is worth mentioning that in combinationFigure 6 As shown, in order to carry more track panels during a single run, two track panel laying devices can be connected and used together. The first flatbed truck 1 of the rear track panel laying device is connected to the second flatbed truck 2 of the front track panel laying device. During use, the slewing and luffing mechanism 4, the first telescopic mechanism 5, and the clamping mechanism 6 of the front track panel laying device cooperate to complete the movement and laying of the track panel. The slewing and luffing mechanism 4, the first telescopic mechanism 5, and the clamping mechanism 6 of the rear track panel laying device move the track panel onto the first flatbed truck 1 or the second flatbed truck 2 of the front track panel laying device. On this basis, the number of track panel laying devices can be continuously increased. Except for the track panel laying device at the predetermined laying position, the remaining subsequent track panel laying devices are all used to move the track panel onto the track panel laying device in front of it, so that multiple track panels can be transported to the predetermined laying position during a single run.

[0062] For the construction method of the track panel laying device in this embodiment, the track panel laying device in Embodiment 1 is adopted, which is convenient for transporting the track panel to the laying position. Through the cooperation of the slewing and luffing mechanism 4, the first telescopic mechanism 5, the second telescopic mechanism 7, and the clamping mechanism, the track panel is hoisted from the bearing mechanism 3 to the laying position. After being aligned by the construction personnel, the track panel is paved at the predetermined paving position, effectively improving the transportation efficiency and paving efficiency of the track panel, and thus being beneficial to improving the construction efficiency of track panel laying.

[0063] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
