[0057] The specific embodiments of the present application will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0058] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0059] In the embodiments of the present application, the orientation words such as “up, down, top, bottom” are generally used for the directions shown in the drawings or the positional relationship between the components in the vertical, perpendicular or gravity direction, unless otherwise specified.

[0060] The present application will be described in detail below with reference to the drawings and in combination with exemplary embodiments.

[0061] Reference Signs List Figures 1 to 7The first exemplary embodiment of the present application provides a track laying system 10, which is suitable for laying operation of different types of tracks, and especially suitable for heavy track laying operation. For example, the track laying system 10 is suitable for laying operation of relatively small tracks such as excavator tracks, and also suitable for heavy track laying operation of heavy construction equipment such as pile drivers, trenchers, etc. The track laying system 10 mainly comprises a support structure, a conveying traction mechanism 103 and a gantry crane traction mechanism 104.

[0062] Specifically, the support structure comprises a feeding support table 101 and a laying support plate 102. The feeding support table 101 is used for feeding the track 20 in roll shape. After feeding from the outside, the track 20 in roll shape is placed on the feeding support table 101 to prepare for laying (i.e. spreading and wrapping). The laying support plate 102 is used for spreading and wrapping the track 20 on the plate. The feeding support table 101 is arranged at one end of the laying support plate 102 along the length direction of the plate, so that the track 20 in roll shape on the feeding support table 101 is easily pulled to the laying support plate 102 by the conveying traction mechanism 103. The support structure as a whole can be installed on the workshop foundation to provide stable support, and the track can be fed close to the ground at this time. Especially for heavy track laying operation, it can reduce the feeding difficulty, shorten the feeding time and improve the safety.

[0063] The conveying traction mechanism 103 is arranged along the length direction of the plate in cooperation with the laying support plate 102. By connecting the conveying traction mechanism 103 with one end of the track 20 in roll shape on the feeding support table 101, and then forming a conveying action along the length direction of the plate by the conveying traction mechanism 103, the track 20 can be gradually pulled to spread on the laying support plate 102. After the track 20 is completely spread, the track frame 30 is moved from the outside to be placed on the spread track 20, and then the track wrapping process can be performed by the gantry crane traction mechanism 104.

[0064] After adjusting the relative position of the spread track 20 and the track frame 30 placed thereon, the gantry crane traction mechanism 104 can hoist and pull the end of the track 20, so that the end of the track 20 is wrapped on the track frame 30, thereby wrapping the track 20. After wrapping, the two ends of the track 20 are connected and fixed, and the assembly of the track 20 and the track frame 30 is completed.

[0065] It should be noted that after the relative positions of the spreaded track 20 and the track frame 30 on which the track 20 is placed are adjusted, if the track frame 30 is very close to one end of the track 20, at this time the gantry crane traction mechanism 104 hoists and pulls the other end of the track 20, and the other end is wrapped on the track frame 30 until the two ends of the track 20 are close enough to be connected to each other, which is a single-end wrapping method. In another case, if the track frame 30 is spaced apart from the two ends of the track 20 (for example, the track frame 30 is placed at the middle of the track 20), at this time the gantry crane traction mechanism 104 hoists and pulls the two ends of the track 20 respectively, so as to wrap the two ends on the track frame 30 respectively until the two ends of the track 20 are close enough to be connected to each other, which is a two-end wrapping method. In practice, the specific wrapping method can be selected according to the actual working conditions, and the present exemplary embodiment does not limit this.

[0066] When the track wrapping system 10 adopting the present exemplary embodiment is used to wrap the track, the conveying and traction mechanism 103 can provide a large traction force to smoothly spread the track 20, and the conveying and traction method has the characteristics of high stability, which can stably support the track 20. In addition, the gantry crane traction mechanism 104 can provide a large traction force to smoothly wrap the track 20, and the whole mechanism is supported by the ground, the center of gravity is stable, and the shaking during hoisting and traction is small, which can greatly reduce the risk of track breakage and mechanism damage. Especially in heavy track wrapping operations, through the stable cooperation of the conveying and traction mechanism 103 and the gantry crane traction mechanism 104, the wrapping difficulty can be greatly reduced, the manpower can be saved, and the wrapping efficiency, operation quality and operation safety can be greatly improved.

[0067] Referring to Figures 1 to 3 , the gantry crane traction mechanism 104 can include a gantry crane 1041, a lifting tool 1043 and two walking tracks 1044. Specifically, the gantry crane 1041 includes a main beam, a lifting device 1042 and two leg assemblies, the main beam is arranged along the width direction of the wrapping support plate 102, the lifting device 1042 is arranged on the main beam, and the two leg assemblies are respectively connected to the two ends of the main beam.

[0068] In addition, the two walking tracks 1044 are respectively arranged on the two sides of the wrapping support plate 102 along the width direction, and the two leg assemblies respectively form walking cooperation with the two walking tracks 1044, so that the whole gantry crane 1041 can walk along the length direction of the wrapping support plate 102. For example, the leg assembly can include a leg body, a roller 1045 arranged at the bottom of the leg body and a walking driving device 1046, the roller 1045 is supported on the corresponding walking track 1044, and the roller 1045 is driven to rotate by the walking driving device 1046, so as to make the roller 1045 roll and walk on the corresponding walking track 1044, thereby driving the whole gantry crane 1041 to walk.

[0069] Further, the lifting device 1042 is connected with the lifting tool 1043, and the lifting tool 1043 can be lifted by the lifting device 1042. For example, the lifting device 1042 can be an electric hoist, and the lifting tool 1043 can be a chain lifting tool.

[0070] Through the above arrangement of the embodiment, the lifting tool 1043 can be connected with the end of the track 20, and the lifting tool 1043 can be lifted by the lifting device 1042 to gradually lift the end of the track 20. When the lifting tool 1043 is at a proper height, the gantry crane 1041 can be moved along the length direction of the laying support plate 102 (i.e., in the direction of approaching the feeding support table 101) to pull the end of the track 20 to be wrapped on the track frame 30. Figure 7

[0071] Further, the walking tracks 1044 can be arranged to match the full length of the laying support plate 102, and the gantry crane 1041 can be arranged to walk along the two walking tracks 1044 to reciprocate in the full length of the laying support plate 102. In this way, when the length of the laying support plate 102 matches the total length of the track 20, the gantry crane 1041 can be walked to the position that the lifting tool 1043 is directly above any end of the track 20, so that the two ends of the track 20 can be respectively pulled in the reverse direction to wrap the track 20, i.e., the two-end wrapping method is adopted.

[0072] Compared with the single-end wrapping method, when the two-end wrapping method is adopted (for example, the track frame 30 is placed at the middle of the track 20), the length of the track segment between the end of the track frame 30 and the adjacent end of the track 20 that can be lifted is relatively short, and the weight of the track segment is relatively light. Especially in the heavy track wrapping condition, the pulling pressure of the lifting tool 1043 can be effectively reduced, and the lifting tool 1043 and the lifting device 1042 can be effectively prevented from being torn, so that the safety operation can be ensured and the reliability can be improved.

[0073] In another case, the feeding of the track 20 in the form of a roll can be realized by the gantry crane pulling mechanism 104. Specifically, one end of the walking track 1044 can be extended to the side area of the feeding support table 101, and both the walking tracks 1044 are arranged in this way. At this time, the gantry crane 1041 can be walked along the two walking tracks 1044 to the position that the lifting tool 1043 is directly above the feeding support table 101, so that the track 20 in the form of a roll can be lifted into the feeding support table 101 by lifting the lifting tool 1043 by the lifting device 1042 when the lifting tool 1043 is directly above the feeding support table 101. In this way, the track laying system 10 can sequentially perform the feeding, laying and wrapping of the track 20, and the degree of automation is high, which greatly improves the production efficiency.​

[0074] With reference to Figure 1 , Figure 2 and Figure 5 , the conveying traction mechanism 103 can adopt a conveying chain traction mechanism, which includes a traction fixed pin 1036 and a conveying chain 1033 used to form a conveying action, the conveying chain 1033 being provided with a chain traction connecting hole 1033a, which needs to be close to the feeding support table 101 before the crawler 20 is laid out. Corresponding to the chain traction connecting hole 1033a, the end of the crawler 20 is provided with a crawler traction connecting hole.

[0075] When the crawler 20 is laid out, one end of the rolled crawler 20 on the feeding support table 101 is first pulled into the adjacent end of the rolling support plate 102, so that the crawler traction connecting hole on the end of the crawler 20 is aligned with the chain traction connecting hole 1033a on the conveying chain 1033, and then the traction fixed pin 1036 is used to pass through and fix the chain traction connecting hole 1033a and the crawler traction connecting hole, so as to fix the end of the crawler 20 on the conveying chain 1033. At this time, the conveying action is formed through the conveying chain 1033, so that the crawler 20 can be gradually pulled out to the rolling support plate 102 until it is completely laid out.

[0076] It can be seen that the way of fixing the conveying chain 1033 and the end of the crawler 20 in this embodiment reasonably utilizes the structure characteristics of easy hole finding of the conveying chain 1033 and the crawler 20, which is a pin hole passing mode convenient for operation, and is conducive to reducing the manufacturing and use cost of the crawler rolling system 10, saving manpower and improving the rolling operation efficiency.

[0077] Further, the conveying chain traction mechanism can include a tightness adjusting device for adjusting the tightness of the conveying chain 1033, so as to prevent the conveying chain 1033 from loosening, falling off or overloading, thereby preventing safety accidents and improving the reliability of the conveying traction mode.

[0078] With reference to Figure 1 , Figure 2 and Figure 5The conveying chain traction mechanism can include a conveying chain mounting table 1031, two sprockets 1032, and a conveying power assembly. Specifically, the conveying chain mounting table 1031 is arranged along the length direction of the laying support plate 102, the two sprockets 1032 are respectively arranged at the two ends of the conveying chain mounting table 1031 along the length direction, the conveying power assembly is used to drive one of the sprockets 1032 to rotate, the conveying chain 1033 is a closed loop chain around the two sprockets 1032, and the conveying chain 1033 is engaged with the two sprockets 1032. When the conveying power assembly drives one of the sprockets 1032 to rotate, the conveying chain 1033 can be driven to form a conveying action, and the other sprocket 1032 can follow the conveying action of the conveying chain 1033 to form rotation. More specifically, the conveying power assembly can include a conveying driving device 1034 and a transmission chain 1035, and the transmission chain 1035, the conveying driving device 1034, and one of the sprockets 1032 together constitute a chain transmission mechanism, so that the power of the conveying driving device 1034 can be transmitted to the sprocket 1032.

[0079] In addition, the top of the conveying chain mounting table 1031 is connected with the laying support plate 102, in order not to affect the support of the laying support plate 102 on the track 20, and at the same time meet the requirement that the conveying chain 1033 can pull the track 20 to spread on the laying support plate 102, a chain groove can be formed in the laying support plate 102, so that the upper segment of the closed loop chain (i.e., the conveying chain 1033) is exposed. In this structure, when the track 20 is supported on the laying support plate 102, the upper segment of the conveying chain 1033 can fix the track 20, for example, through the chain traction connecting hole 1033a mentioned above, so as to pull the track 20 to spread on the laying support plate 102.

[0080] The conveying chain traction mechanism in the embodiment has the advantages of compact cooperation with the laying support plate 102, simple structure, stable support of the track 20, and traction of the track 20 to spread, and the like.

[0081] With reference to Figures 1 to 5 In addition, the track laying system 10 can further be provided with a support rotating mechanism 105 arranged on the feeding support table 101. The support rotating mechanism 105 can keep the winding part of the track 20 in place during the spreading of the track 20, that is, the winding part of the track 20 can be gradually released and spread to the laying support plate 102, and the position of the winding part can be stable, so that the winding part does not fall out of the feeding support table 101 and affect the normal laying operation or cause a safety accident.

[0082] As an example, the supporting rotating mechanism 105 can include a supporting rotating shaft 1052 and two supporting rotating frames 1051. The two supporting rotating frames 1051 are arranged in parallel and spaced apart on the feeding supporting table 101, and the top surfaces of the two supporting rotating frames 1051 are respectively formed with two arc-shaped supporting grooves. In addition, the supporting rotating shaft 1052 is a detachable rotating shaft. Before the crawler belt spreading operation, the supporting rotating shaft 1052 can be inserted through the winding center hole of the roll-shaped crawler belt 20, and then the supporting rotating shaft 1052 is overlapped on the two arc-shaped supporting grooves, so that the roll-shaped crawler belt 20 is located between the two supporting rotating frames 1051. During the crawler belt spreading operation, the supporting rotating shaft 1052 is rotatably overlapped on the two arc-shaped supporting grooves, which ensures that the winding part of the crawler belt 20 is stably released to the winding supporting plate 102 and keeps rotating in place, effectively preventing the winding part from falling out of the feeding supporting table 101.

[0083] It should be noted that after the supporting rotating shaft 1052 is inserted through the winding center hole of the roll-shaped crawler belt 20, if the portal crane traction mechanism 104 can realize the feeding of the roll-shaped crawler belt 20, the lifting device 1042 can be used to drive the lifting device 1043 to lift the two ends of the supporting rotating shaft 1052, so as to synchronously drive the supporting rotating shaft 1052 and the roll-shaped crawler belt 20 to lift, thereby the supporting rotating shaft 1052 can be overlapped on the two arc-shaped supporting grooves.

[0084] To further improve the stability of the winding part of the crawler belt 20 during release, two limiting baffles 1053 can be connected to the supporting rotating shaft 1052. The two limiting baffles 1053 are arranged in parallel and spaced apart along the axial direction of the supporting rotating shaft 1052, and can respectively axially limit the axial ends of the winding part of the crawler belt 20, so as to avoid the axial displacement of the winding part during release, thereby improving the stability.

[0085] Referring to Figure 1 , Figure 2 and Figure 6 , the crawler belt winding system 10 can include a centering positioning mechanism for centering and positioning the crawler belt 20 after it is completely spread out, so that the crawler belt 20 is completely arranged along the length direction of the winding supporting plate 102, thereby correcting the crawler belt 20 before placing the crawler belt frame 30, ensuring that the relative position of the crawler belt frame 30 and the crawler belt 20 is correct after the crawler belt frame 30 is placed, and thereby facilitating the smooth execution of the subsequent crawler belt winding operation.

[0086] Specifically, the centering mechanism comprises at least one centering group 106, and when a plurality of centering groups 106 are provided, the plurality of centering groups 106 are arranged in sequence along the plate length direction of the laying support plate 102. For a single centering group 106, it comprises two lateral pressing structures, which are arranged on both sides of the laying support plate 102 along the plate width direction, and at least one of the two lateral pressing structures can form a displacement action along the plate width direction of the laying support plate 102, so that the track 20 can be centered by forming the displacement action.

[0087] For example, in the same centering group 106, one of the lateral pressing structures can be set as a fixed pressing structure 1061, and the other lateral pressing structure can be set as a movable pressing structure 1062. The movable pressing structure 1062 comprises a screw nut mechanism 1062a, a pressing driving device 1062b, a pressing frame, two pressing rails 1062e and two pressing plates 1062f. Among them, the screw nut mechanism 1062a is arranged along the plate width direction, the two pressing rails 1062e are arranged on both sides of the screw nut mechanism 1062a along the plate length direction, the pressing frame comprises a connecting rod 1062d and two sliding rods 1062c, the two sliding rods 1062c are respectively in sliding cooperation with the two pressing rails 1062e, the connecting rod 1062d connects the two sliding rods 1062c and is fixedly connected with the nut in the screw nut mechanism 1062a, the two sliding rods 1062c are respectively connected with the two pressing plates 1062f at one end close to the laying support plate 102, and the pressing driving device 1062b is used to drive the screw in the screw nut mechanism 1062a to rotate.

[0088] Based on the above setting, when the track is centered, the screw in the screw nut mechanism 1062a is driven to rotate by the pressing driving device 1062b, so that the nut in the screw nut mechanism 1062a is displaced along the screw, and the pressing frame fixed with the nut gradually approaches the edge of the track 20, and when the two pressing plates 1062f abut against the edge of the track 20, the track 20 can be pushed to displace. Until the other side edge of the track 20 is pressed against the fixed pressing structure 1061, and the track 20 stops displacing, at this time, the centering of the track 20 is completed.

[0089] The second exemplary embodiment of the present application also provides a track laying method, which is executed by using the track laying system described above, and the method comprises the following steps:

[0090] Step S1: connecting one end of the track 20 in roll shape on the feeding support table 101 with the conveying traction mechanism 103;
