Technical Field

[0001] The present invention relates to the field of railway engineering, and in particular to a replacement construction method for a telescopic adjuster. Background Art

[0002] As the line operates for longer, the damage to the tracks within the range of the telescopic device and telescopic adjuster gradually increases, and the vertical stiffness of some telescopic devices is too strong, and the transition between the stiffness of the telescopic device and the front and rear tracks is uneven, resulting in problems such as train jumping, poor track geometry, and frequent damage to components during line operation. When maintenance and repair cannot meet the line operation requirements, the telescopic adjuster needs to be replaced.

[0003] The existing construction method for replacing telescopic adjusters requires a large amount of construction work, and existing operating lines can only be constructed during the window period. The window period is limited, the construction workload is large, and the construction period is tight, making it difficult to ensure the construction progress and the normal operation of the line. Summary of the Invention

[0004] The main purpose of the present invention is to provide a replacement construction method for a telescopic adjuster, which can solve the problem that the existing replacement construction method for the telescopic adjuster has a large construction workload during skylight time and is difficult to ensure normal operation of the line during the day.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a replacement construction method for a telescopic adjuster is provided, comprising: sawing the rails at both ends of the original telescopic device and the original telescopic adjuster; removing the original telescopic adjuster and the sleepers; detachably connecting the new telescopic adjuster sleepers and temporary rails to form an integral track, and then laying the integral track on the line; removing the original telescopic device and replacing it with a new telescopic device; pre-installing the new telescopic adjuster and the pad, and after the installation is completed, laying the entire track on the line; and performing line fine-tuning.

[0006] Furthermore, the step of sawing the rails at both ends of the original telescopic device and the original telescopic adjuster includes: before sawing the rails at both ends of the original telescopic device and the original telescopic adjuster, you can choose whether to remove the sleepers at both ends of the original telescopic device and replace them with temporary sleepers according to actual needs; when replacing the sleepers of the new adjuster, it is necessary to remove the temporary sleepers while removing the rails and sleepers within the range of the original telescopic adjuster.

[0007] Furthermore, the step of detachably connecting the replaced regulator sleepers and the temporary rails to form an integral track includes: connecting the replaced regulator sleepers and the temporary rails with temporary fasteners to form an integral track.

[0008] Furthermore, the entire track is laid using a one-time lifting method.

[0009] Furthermore, the replacement construction method of the telescopic adjuster also includes: after the entire track is laid on the line, the joints between the temporary rails and the original rails remaining on the line are connected and fixed using splints.

[0010] Furthermore, the steps of removing the original telescopic device and replacing it with a new one include: sawing the welded steel ballast plate and steel sleeper of the bridge connected to the original telescopic device; removing the original telescopic device; laying the new telescopic device rails at the location of the original telescopic device; and closely and fixedly connecting the sleepers on both sides of the new telescopic device ballast plate to the steel ballast plate welded on the bridge.

[0011] Furthermore, the new expansion adjuster is pre-installed with the iron pad, and after the installation is completed, the steps of laying it on the line include: removing the temporary rails before laying, and welding the joints between the new expansion adjuster and the original line rails after laying is completed.

[0012] Furthermore, the step of installing the remaining longitudinal beams of the new telescopic device includes: connecting the movable steel sleepers and the fixed sleepers to the longitudinal beams through the iron buckle system.

[0013] Furthermore, the replacement construction method of the telescopic adjuster also includes: after the remaining longitudinal beams of the new telescopic device are installed, tightening the bolts at each connection.

[0015] By applying the technical solution of the present invention, when replacing the adjuster, the rails at both ends of the original telescopic device and the original telescopic adjuster are first sawed, and then the original telescopic adjuster and sleeper are removed. Before replacing the new telescopic adjuster sleeper, the new telescopic adjuster sleeper and temporary rail are pre-installed so that the new telescopic adjuster sleeper and temporary rail form an integral track row, and then the assembled integral track row is laid on the line, the original telescopic device is removed, and the new telescopic device is laid at the corresponding position. The new telescopic adjuster and the pad are pre-installed. After the installation is completed, the entire track row is laid to the corresponding position of the line, and finally the line is fine-tuned. During the replacement process, the new telescopic adjuster sleeper and temporary rail can be pre-installed before laying at non-window time, and the new telescopic adjuster and the pad can also be pre-installed before laying at non-window time. In this way, the entire track row can be directly laid directly during the window time, which can speed up the construction progress, thereby ensuring that the replacement task is successfully completed within the limited construction time and does not affect the normal operation of the line.

[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] like Figure 1 As shown, the present invention provides a construction method for replacing a telescopic adjuster, comprising: sawing the rails at both ends of the original telescopic device and the original telescopic adjuster; removing the original telescopic adjuster and the sleeper; detachably connecting the new telescopic adjuster sleeper and the temporary rail to form an integral track, and then laying the integral track on the line; removing the original telescopic device and replacing it with a new telescopic device; pre-installing the new telescopic adjuster and the pad, and after the installation is completed, laying the entire track on the line; and performing line fine-tuning.

[0022] In this embodiment, the specific steps of the construction method for replacing the telescopic adjuster are as follows: first, the rails at both ends of the original telescopic device and the original telescopic adjuster are sawed, and then the original telescopic adjuster and sleepers are removed. Before replacing the new telescopic adjuster sleepers, the new telescopic adjuster sleepers and temporary rails are pre-installed so that the new sleepers and temporary rails form an integral track row, and then the assembled integral track row is laid on the line, the original telescopic device is removed, and the new telescopic device is laid at the corresponding position, and the new telescopic adjuster and the pad are pre-installed. After the installation is completed, the entire track row is laid to the corresponding position of the line, and finally the line is fine-tuned. In the above replacement process, the new telescopic adjuster sleepers and temporary rails can be pre-installed before laying during non-window time, and the new telescopic adjuster and the pad can also be pre-installed before laying during non-window time. In this way, the entire track row can be directly laid during the window time, which can speed up the construction progress, thereby ensuring that the replacement task is successfully completed within the limited construction time and does not affect the normal operation of the line.

[0023] The adjuster replacement method of the embodiment of the present application disconnects the integrated structure formed by the original telescopic device and the telescopic adjuster by sawing the rails and using temporary rails to temporarily replace the telescopic adjuster, so that the integrated replacement process of the telescopic device and the telescopic adjuster can be decomposed into independent units that do not affect each other for construction. The process is reasonably split, the construction time required for a single process is shortened, and the work arrangement is more reasonable. The replacement of the telescopic device and the telescopic adjuster can be arranged to be operated at different skylight times, which can save construction time, make full use of discontinuous skylight times, ensure the smooth completion of the replacement, and maximize the normal operation of the line.

[0024] like Figure 2 As shown, in one embodiment of the present invention, the step of sawing the rails at both ends of the original telescopic device and the original telescopic adjuster includes: before sawing the rails at both ends of the original telescopic device and the original telescopic adjuster, you can choose whether to remove the sleepers at both ends of the original telescopic device and replace them with temporary sleepers according to actual needs; when replacing the sleepers of the new telescopic adjuster, it is necessary to remove the temporary sleepers while removing the rails and sleepers within the range of the original telescopic adjuster.

[0025] In this embodiment, before sawing the rails at both ends of the original telescopic device and the original telescopic adjuster, the staff can choose whether to remove the sleepers at both ends of the original telescopic device and replace them with temporary sleepers according to actual needs. If the construction environment is relatively good and the construction volume is small, the staff can complete the replacement without affecting normal traffic, and there is no need to remove the sleepers at both ends of the original telescopic device and replace them with temporary sleepers. When the construction environment is relatively harsh, such as encountering heavy snow or heavy rain, the staff cannot complete the replacement within the skylight time. In order not to affect normal traffic, it is necessary to remove the sleepers at both ends of the original telescopic device and replace them with new telescopic adjuster sleepers. When replacing the new telescopic adjuster sleepers later, it is necessary to remove the rails and sleepers within the range of the original telescopic adjuster and also remove the temporary sleepers.

[0026] In one embodiment of the present invention, the step of detachably connecting the new telescopic adjuster sleeper and the temporary rail to form an integral track comprises: connecting the new telescopic adjuster sleeper and the temporary rail with temporary fasteners to form an integral track.

[0027] In this embodiment, the new telescopic adjuster sleepers and the temporary rails are connected by temporary fasteners. The new telescopic adjuster sleepers, temporary fasteners and temporary rails can form an integral track, which is convenient for subsequent laying and installation. Moreover, the connection process of the replacement sleepers and the temporary rails can be carried out during non-window time and does not occupy window time, thereby ensuring that the staff can successfully complete the replacement task within a limited construction time.

[0028] In one embodiment of the present invention, the entire track is laid by a one-time hoisting method.

[0029] In this embodiment, the entire track is laid using a one-time hoisting method, which can save manpower and reduce construction difficulty, and can also improve replacement efficiency and ensure that the replacement can be completed within the construction period.

[0030] In one embodiment of the present invention, the construction method for replacing the telescopic adjuster further includes: after the entire track is laid on the line, the joints between the temporary rails and the original rails remaining on the line are connected and fixed using splints.

[0031] In this embodiment, the joints between the temporary rails and the original rails remaining on the line are connected and fixed with splints to ensure the normal operation of the line without affecting traffic. In addition, this splint fixing method is convenient for assembly and disassembly and can achieve longitudinal and transverse positioning.

[0032] like Figure 3 As shown, in one embodiment of the present invention, the steps of removing the original telescopic device and replacing it with a new telescopic device include: sawing the welded steel ballast plate and steel sleepers of the bridge connected to the original telescopic device; removing the original telescopic device; laying the new telescopic device track at the position of the original telescopic device; and tightly and fixedly connecting the sleepers on both sides of the new telescopic device ballast plate to the steel ballast plate welded on the bridge.

[0033] In this embodiment, before installing the new telescopic device, it is necessary to first saw off the welded steel ballast plate and steel sleepers of the bridge connected to the original telescopic device, so that the original telescopic device can be disassembled. Then the track composed of the new telescopic device can be laid in the corresponding position, and finally the sleepers on both sides of the ballast plate are tightly fixed to the steel ballast plate welded on the bridge to complete the replacement of the new telescopic device, thereby ensuring the normal operation of the line.

[0034] In one embodiment of the present invention, the new expansion adjuster is pre-installed with the iron pad, and the step of laying the new expansion adjuster on the line after the installation is completed includes: removing the temporary rail before laying, and welding the joint between the new expansion adjuster and the original line rail after the laying is completed.

[0035] In this embodiment, the temporary rails are removed before laying to provide installation space for the new expansion adjuster. After the new expansion adjuster is laid, the joint between the new expansion adjuster and the original line rails is welded to complete the installation of the new expansion adjuster and ensure the normal operation of the line.

[0036] In one embodiment of the present invention, the step of installing the remaining longitudinal beams of the new telescopic device includes: connecting both the movable sleepers and the fixed sleepers to the longitudinal beams through a fastening system.

[0037] In this embodiment, the movable steel sleepers and fixed rail sleepers are connected to the longitudinal beams through a buckle system, and the movable steel sleepers can slide longitudinally along the longitudinal beams to ensure that when the displacement of the bridge and the track is inconsistent, the telescopic adjuster and the telescopic device can perform corresponding coordinated deformation, thereby ensuring the normal operation of the line and improving the stability of the line operation.

[0038] In one embodiment of the present invention, the construction method for replacing the telescopic adjuster further includes: after the remaining longitudinal beams of the new telescopic device are installed, tightening the bolts at each connection.

[0039] In this embodiment, after the remaining longitudinal beams of the new telescopic device are installed, it is necessary to tighten the bolts at each connection to reach the designed torque, and adjust the gauge, track direction, height, level and other indicators within the scope of the telescopic adjuster and the telescopic device to ensure the installation stability between the new telescopic device, the new telescopic adjuster and the longitudinal beams, which can enhance the structural strength and torsional resistance, improve the structural stability and provide greater anti-rollover ability.

[0040] In one embodiment of the present invention, the step of performing line fine-tuning includes: installing a longitudinal beam of a new telescopic device before performing line fine-tuning.

[0041] In this embodiment, if the weight of the multiple longitudinal beams included in the new telescopic device is within the bearing capacity of the crane, all the longitudinal beams can be assembled and laid together with other parts of the new telescopic device. If the weight of the multiple longitudinal beams included in the new telescopic device exceeds the bearing capacity of the crane, the bearing capacity of the crane and the construction safety are difficult to guarantee. At this time, the longitudinal beams can be installed in multiple times according to actual conditions.

[0042] In one embodiment of the present invention, the replacement construction method of the telescopic adjuster further includes: after each road is started, manual tinkering is performed first and then road maintenance is performed by a large machine.

[0043] In this embodiment, each time the track is replaced, manual work is first performed and then road maintenance is performed by a large machine. After the replacement process is completed, the line needs to be fine-tuned to ensure smooth operation of the line.

[0044] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when replacing the adjuster, the rails at both ends of the original telescopic device and the original telescopic adjuster are first sawed, and then the original telescopic adjuster and sleeper are removed. Before laying the new sleeper, the new sleeper and temporary rail are pre-installed so that the new sleeper and the temporary rail form an integral track. Then the assembled integral track is laid on the line, the original telescopic device is removed, and the new telescopic device is laid at the corresponding position. The new telescopic adjuster and the pad are pre-installed. After the installation is completed, the entire track is laid to the corresponding position of the line, and then the remaining longitudinal beams of the new telescopic device are installed. Finally, the line is fine-tuned. During the replacement process, the new sleeper and temporary rail can be pre-installed before laying in non-window time, and the new telescopic adjuster and the pad can also be pre-installed before laying in non-window time. In this way, the entire track can be laid directly during the window time, which can speed up the construction progress, thereby ensuring that the replacement task is successfully completed within the limited construction time and does not affect the normal operation of the line.
