The rail normalizing system includes induction normalizing equipment and large equipment such as cooling equipment, control equipment, power equipment, etc. The equipment is large in number, large in size and heavy in weight.

[0004] In order to facilitate the overall transportation of the rail on-site normalizing operation system for on-site operations at different on-site operation points, the rail on-site normalizing operation system is constructed as a container-type structure as a whole.

[0078] The present invention is more fully described below with reference to the accompanying drawings in which exemplary embodiments of the present invention are illustrated. However, the present invention may be implemented in different forms and should not be construed as being limited to the embodiments given herein. The above embodiments are given to make the disclosure herein comprehensive and complete, so that the understanding of the scope of protection of the present invention is more comprehensive and accurate.

[0079] Terms such as “comprise” and “include” indicate that in addition to the components directly and explicitly stated in the specification and claims, the technical solution of the present invention does not exclude the situation where it has other components that are not directly or explicitly stated.

[0080] Terms such as “first” and “second” do not indicate the order of units or components in terms of time, space, size, etc., but are merely used to distinguish between units or components.

[0081] For the convenience of explanation, Figures 1 to 17 The x-direction, y-direction and z-direction are defined in the text, wherein the height direction of the rail working vehicle / rail on-site normalizing system is defined as the z-direction, and the direction of the axle of the corresponding wheelset of the rail working vehicle / the width direction of the rail on-site normalizing system is defined as the y-direction. The x-direction is perpendicular to the y-direction and the z-direction, and is roughly along the direction of the track on which the wheels of the rail working vehicle travel / along the length of the rail on-site normalizing system. For the convenience of clear description, the positive direction of the x-direction is pointed to the rear / end of the rail working vehicle, that is, to the on-site operation point of the rail on-site normalizing system, and the positive direction of the y-direction is pointed to the right side of the rail working vehicle. And, in the following description of the attached Figures 1 to 17 In the description, the directional terms such as "front / head" and "rear / tail" are defined relative to the x direction, the directional terms such as "left" and "right" are defined relative to the y direction, and the directional terms such as "up" and "down" are defined relative to the z direction. It should be understood that the definitions of these directions are used for the description and clarification of relative positions, which may change accordingly according to the changes in the orientation of the rail working vehicle / rail field normalizing system, etc.

[0082] The following combination Figures 1 to 9 The rail working vehicle 20 and the rail field working assembly 1000 of one embodiment of the present invention are described as an example. The rail working vehicle 20 can travel along the track, and can be used to carry one or more rail field working systems 10 to the site for offline operation or online operation; wherein online operation and offline operation are two operation modes mainly defined for the placement of rails. The operation of placing rails on both sides of the line is called offline operation, and the operation of the rails themselves being pressed under the wheels of the rail working vehicle 20 is called online operation.

[0083] like Figure 1 and Figure 2As shown, the rail working vehicle 20 can be implemented in the form of a rail flat car, wherein the frame 21 serves as the main body of the rail working vehicle 20, and its upper surface is formed with a roughly flat surface for carrying the rail field working system 10, so it can also be called a "rail flat car". The dimensions of the rail working vehicle 20 in the x-direction and the y-direction can be designed according to the size and / or number of the rail field working systems 10 it carries. The rail working vehicle 20 also includes a wheelset, and the frame 21 is supported by the wheelset; generally, the wheelset has an axle 233 and wheels 231 respectively arranged at the left and right ends of the axle 233, and the wheelset can travel on the rails through the two wheels 231.

[0084] like Figure 1 and Figure 2 As shown, the rail working vehicle 20 also includes an electric transmission assembly corresponding to the wheel pair, and a traction motor 221 that outputs power to the electric transmission assembly. The traction motor 221 can be fixedly mounted on the crossbeam of the vehicle frame 21. Through the traction motor 221 and the electric transmission assembly, the wheels 231 can be driven to move on the rails, thereby enabling the rail working vehicle 20 to move independently.

[0085] The applicant has noticed that currently existing rail working vehicles 20 are generally equipped with a dedicated diesel engine to directly drive the corresponding hydraulic pump to output power so as to drive the rail working vehicle to travel, and the rail field normalizing operation system 10 carried by the rail working vehicle 20 is usually also equipped with a corresponding generator set for field operation. The traction motor 221 of an embodiment of the present invention is configured to obtain the power required to drive the rail working vehicle 20 to travel independently in the following manner: when carrying the rail field operation system 10, the traction motor 221 is detachably electrically connected to the generator set 12 in the rail field operation system 10 carried by the rail working vehicle 20, so that the traction motor 221 is mainly or entirely provided with power by the generator set 12. In this way, the generator set 12 of the rail field operation system 10 that needs to be carried, and even the corresponding diesel engine, etc. can be shared by the rail field operation system 10 and the rail operation vehicle 20, and there is no need to specially set a diesel engine, etc. on the rail operation vehicle 20 in a traditional way to drive the hydraulic pump and other output power to drive it to move; compared with the prior art, for example, a dedicated diesel engine is set for the rail operation vehicle to directly drive the corresponding hydraulic pump to output power to drive the rail operation vehicle to move, the rail operation vehicle 20 of the embodiment of the present invention does not need to be equipped with a diesel engine, etc., even if a traction motor 221 and an electric transmission component are set on the rail operation vehicle 20, it can still be implemented at a relatively low cost, which is easy to be accepted by users, and has a simple structure, a small installation space, and can achieve electric drive.

[0086] It should be understood that the above-mentioned "sharing" is made by the applicant after comprehensive consideration of the application characteristics of the rail field operation system 10 that does not need to use electricity to perform field operations when it is carried, and the rail operation vehicle 20 does not need to be driven by electricity to move when the rail field operation system 10 performs field operations. Therefore, it can meet the application requirements of the rail operation vehicle 20 and the rail field operation system 10 at the same time. Even if the generator set 12 is "shared", it will not cause the power demand contradiction between the rail operation vehicle 20 and the rail field operation system 10. The power of the traction motor 221 is also easy to be guaranteed, which is easy to meet the characteristics of the high-power drive requirements of rail transit transportation, and is basically not limited by the cruising range (for example, if a power battery module is used to power the traction motor 221, the cruising range and power are difficult to meet the requirements of the rail field operation system 10 with a large carrying weight). Moreover, the detachable electrical connection between the traction motor 221 and the generator set 12 in the rail field operation system 10 is also very easy to achieve, for example, it can be achieved by a simple plug-in operation between the corresponding cable interface ends; compared to the ground, if a diesel engine is used to output power through a hydraulic pump to drive the rail operation vehicle, the connection between the diesel engine and mechanical transmission components such as the hydraulic pump is very difficult.

[0087] In one embodiment, if Figure 2 As shown, the electric transmission assembly may include a transmission shaft 223 and a coupling 225, wherein the coupling 225 may be a universal coupling (e.g., a cross universal coupling), the transmission shaft 223 is located directly above the axle 233 and crosses the axle 233 in a "cross" shape, one end of the transmission shaft 223 may be rigidly connected to the output end flange of the traction motor 221, the other end of the transmission shaft 223 is connected to one end of the universal coupling 225, and the other end of the universal coupling 225 is connected to the input end of an axle gearbox 227 installed on the axle, the universal coupling 225 works together with the axle gearbox 227, and the power transmitted by the transmission shaft 223 can be output to the axle 233 in the corresponding wheel set; thereby, the traction motor 221 can drive the axle 233 to rotate, thereby driving the wheels to rotate.

[0088] In another alternative embodiment, Figure 6 As shown, there are two universal couplings 225, namely universal couplings 225a and 225b, which can be connected by a shaft; of course, the universal couplings 225a and 225b can also be regarded as a universal coupling with two universal free connection ends, so that it is necessary to set the following Figure 2The transmission shaft 223 in the transmission shaft 223. The first universal coupling 225a is connected to the output end of the traction motor 221 (for example, by bolts), and the second universal coupling 225b is connected to the axle gearbox 227 (for example, by bolts). In this way, the universal free connection at both ends can avoid damage to the axle gearbox 227 caused by motor vibration, motor jump or axial deflection, which is beneficial to protecting the traction motor 221 and the gearbox 227.

[0089] Continue as Figure 2 As shown, in one embodiment, an electric transmission assembly and a traction motor 221 are correspondingly provided for each set of wheelsets. Taking two sets of wheelsets as an example, the front and rear sets of wheelsets are respectively provided with a transmission shaft 223, a universal coupling 225, an axle gear box 227 and a traction motor 221, so that the wheelsets can be driven respectively. It will be understood that the number of wheelsets can be increased as needed, and the transmission shaft 223, the universal coupling 225, the axle gear box 227 and the traction motor 221 etc. provided corresponding to the wheels can also be increased accordingly.

[0090] Continue as Figure 2 As shown, in one embodiment, the electric transmission assembly (e.g., transmission shaft 223, universal coupling 225, axle gear box 227) and traction motor 221 correspondingly provided for the first set of wheelsets and the electric transmission assembly (e.g., transmission shaft 223, universal coupling 225, axle gear box 227) and traction motor 221 correspondingly provided for the second set of wheelsets can be arranged substantially symmetrically along a center line 2331, and the center line 2331 is parallel to the direction of the axle 233 of the wheelsets, that is, parallel to the y direction, and can be located in the middle of the two transmission shafts 223. In this way, it is conducive to achieving a reasonable layout and a stable center of gravity.

[0091] Continue as Figure 1 and Figure 2 As shown, in one embodiment, a plurality of locking components 212 are provided on the frame 21 of the rail working vehicle 20, and the locking components 212 are used to detachably install and lock the rail field working system 10 on the frame 21, so that the rail field working system 10 can be conveniently disassembled and assembled on the frame 21, for example, the rail field working system 10 can be hoisted onto the rail working vehicle 20 using equipment such as a large crane, and then aligned and locked for installation, otherwise it can be conveniently removed from the frame 21. It should be noted that when disassembling and assembling the rail field working system 10 on the rail working vehicle 20, for example, electrical connection or electrical disconnection operations between the traction motor 221 and the generator set 12 can also be conveniently performed at the same time; and there is no need to perform a coupling operation between the transmission systems (the coupling operation is usually very complicated).

[0092] The rail working vehicle 20 of the above embodiment can be used to carry any type of rail field working system 10 with a generator set by providing a locking assembly 212 and a corresponding traction motor 221 and an electric transmission assembly, and can also be used to carry different rail field working systems 10 of the same type, that is, the rail working vehicle 20 can carry multiple rail field working systems 10 respectively, greatly improving its versatility. In one embodiment, the rail field working system 10 carried by the rail working vehicle 20 can be a box-type rail normalizing treatment system, which has a container-structured cabin 11, which is convenient for overall transportation like a container. The box-type rail normalizing treatment system can be used to complete the on-site normalizing heat treatment operation for the rail, thereby improving the toughness and other properties of the welded joints of the rail to meet the corresponding standard requirements. It should be understood that the specific type, structure, etc. of the rail field operation system 10 carried by the rail operation vehicle 20 in the above embodiment is not restrictive. In other embodiments, the rail field operation system 10 can also be a rail welding field operation system, a rail grinding field operation system, a welding flaw detection field operation system, etc.

[0093] In one embodiment, if Figure 6 Shown and Figure 7 As shown, the locking assembly 212 may include a twist lock 2121, a twist lock nut 2122, a gasket 2123, and a cotter pin 2124; through the twist lock 2121, the twist lock nut 2122, the gasket 2123, the cotter pin 2124, and the boss 2125 with a groove, the locking assembly 212 may detachably lock the cabin 11 of the rail field operation system 10 on the frame 21 of the rail operation vehicle 20. For example, as Figure 6(b), the boss 2125 can be fixed on the frame 21 (for example, fixed on the frame 21 by welding), the turn lock 2121 includes a head and a rod portion having a smaller radial dimension relative to the head, the rod portion of the turn lock 2121 sequentially passes through the boss 2125 (the boss 2125 can be provided with a corresponding through hole), the cabin 11, the frame 21 (the frame 21 can be provided with a corresponding through hole), the gasket 2123 and the turn lock nut 2122, and the turn lock nut 2122 is threadedly fastened to the turn lock 2121 The lower end of the rod; after the turn lock 2121 is rotated by a predetermined angle (for example, 90°), the head of the turn lock 2121 can be at least partially seated in the groove 2126 of the boss 2125 and restricted from rotation by the groove 2126. When locked, the turn lock nut 2122 is threadedly fastened to the lower end of the rod of the turn lock 2121, and the cotter pin 2124 passes through the through hole on the lower end of the rod of the turn lock 2121 to prevent the turn lock nut 2122 from loosening the thread. The gasket 2123 can be placed between the turn lock nut 2122 and the frame 21. During the locking and installation process of the locking assembly 212 of the above embodiment, the rotary lock 2121 is rotated 90° so that the rotary lock 2121 falls into or seats in the groove 2126 of the boss 2125, thereby effectively preventing the rotary lock 2121 from rotating due to, for example, long-term vibration or external force during use; further, the rotary lock nut 2122 is tightened and the cotter pin 2124 is installed, so that the cabin 11 can be conveniently locked on the frame 21. Therefore, the locking assembly 212 of the above embodiment is convenient to operate and has good locking reliability.

[0094] Specifically, when the cabin 11 of the rail field operation system 10 needs to be locked and installed on the rail operation vehicle 20, the upper end of the rotary lock 2121 is lifted and rotated 90 degrees, and then the rotary lock 2121 is pressed on the bottom step on the inner side of the box corner 118 of the cabin 11, and at the same time, the rotary lock 2121 falls into the groove of the grooved boss 2125, and the rotary lock nut 2122 is further tightened, and then the cotter pin 2124 is installed to prevent the thread from loosening; after multiple locking assemblies 212 complete such operations, the operation of locking the cabin 11 on the rail operation vehicle 20 is completed; when the cabin 11 needs to be removed from the rail operation vehicle 20, the cotter pin 2124 can be removed in sequence, the rotary lock nut 2122 can be loosened, the rotary lock 2122 can be lifted, and then rotated 90 degrees in the opposite direction. At this time, the rotary lock 2122 is parallel to the bottom opening of the box corner 118 of the cabin 11, so that the removal operation can be easily achieved. The entire locking installation and removal process is simple and easy to operate.

[0095] Continue as Figures 1 to 4 As shown, in one embodiment, each wheel of the corresponding wheel pair is also provided with a corresponding brake assembly 235 , and the brake assembly 235 can be implemented by a pneumatic brake cylinder, etc., and the power required by the pneumatic brake cylinder, such as an air compressor, can also be provided by the generator set 12 .

[0096] It should be noted that the traction motor 221 can adapt to external force and reverse at a low speed. In this way, the gear shifting design of the axle gearbox 227 required for the hydraulic transmission or hydrodynamic transmission when coupled can be avoided, that is, the axle gearbox 227 can be further designed as an axle gearbox without a gear shifting mechanism or without a gear shifting mechanism; the gearbox without a gear shifting mechanism can also avoid the safety risk of the hydraulic motor being reversed and damaged when the hydraulic transmission or hydrodynamic transmission forgets to shift to neutral.

[0097] As a comparative explanation of the understanding of the above embodiments, in the case where the traditional hydraulic drive is to drive the axle gearbox to transmit power to the axle and wheels for operation through a hydraulic motor (for example, driven by a dedicated diesel engine), the internal structure of the hydraulic motor limits the motor from rotating in the opposite direction under the action of external force. Therefore, if the coupling drag is sent and reversed, the hydraulic motor is easily damaged. Therefore, in the prior art, if it is coupled and dragged, it is necessary to disengage the hydraulic motor and the axle gearbox, that is, to perform a neutral operation, so that the motor will not passively reverse when the wheels and axles rotate. The prior art neutral operation further requires the existing axle gearbox to have a shifting mechanism (such as a torque converter), and its structure becomes very complicated, and the shifting mechanism is prone to failure. Once the disengagement fails, the hydraulic motor will be driven to reverse and damaged.

[0098] The axle gearbox 227 without a shifting mechanism can specifically but is not limited to adopting a two-stage intersecting shaft gear transmission, for example, the first stage is a cylindrical gear pair and the second stage is a spiral bevel gear pair; the axle gearbox 227 can illustratively include a box body, a gear pair, a bearing pair, a sealing system, a lubrication system, etc.

[0099] In one embodiment, the traction motor 221 may be a motor that can be reversed by external force and has a stepless speed change function, such as a variable frequency DC or AC motor.

[0100] In one embodiment, a leaf spring can be arranged between the frame 21 of the rail working vehicle 20 and the bogie, and the leaf spring can be used as a shock absorbing mechanism. Generally, the axle box of a railway bogie is relatively large, and a group of springs (for example, composed of 2 springs) can be arranged and positioned on the axle box through a more complex structure; however, the two-axle structure bogie corresponding to one embodiment of the present invention has a relatively small axle box, and there is not enough space to arrange the two springs, and the springs are easily eccentric and the strength is not enough. Taking these factors into consideration, the leaf spring selected in this embodiment can be better applied to the two-axle structure bogie structure with a small axle box and a small installation space, and the leaf spring has a sufficiently large strength.

[0101] Continue as Figures 1 to 4As shown, the head end and the tail end of the frame 21 are respectively provided with different types of couplers 25a and couplers 25b. In this way, when, for example, the generator set 12 fails and causes the rail working vehicle 20 to lose power and be unable to evacuate the scene, the couplers can enable the rail working vehicle 20 to add a vehicle coupling function, so that a rescue rail vehicle can be used to couple the rail working vehicle 20 through the coupler 25a or 25b and tow the rail working vehicle 20 away from the scene.

[0102] In one embodiment, if Figure 7 and Fig. 9 As shown, the hook 25b at one end close to the on-site operation point is set as a towing hook 25b with a relatively low height and no unhooking device, for example, the upper end surface of the towing hook 25b is lower than the height of the bottom frame of the cabin 11. In this way, when the crane 16 transports the induction normalizing device 30, the towing hook 25b will not collide with the induction normalizing device 30, and the towing hook 25b will not interfere with or affect the transport operation.

[0103] Continue as Figures 1 to 4 As shown, the rail working vehicle 20 may be provided with a driving light 216 and / or a clearance light 219. For example, the driving light 216 is provided on the front end face and the rear end face of the vehicle frame 11, and a plurality of clearance lights 219 are provided on the side of the vehicle frame 11. The driving light 216 improves the driving condition of the rail working vehicle 20, for example, in a tunnel, and the clearance light 219 can provide safety tips for on-site workers when the rail working vehicle 20 is driving at a low speed.

[0104] Continue as Figures 1 to 4 As shown, the rail working vehicle 20 further includes a cab 24, which is fixedly arranged at the head or tail of the frame 21, for example, arranged at the head. The cab 24 can be formed by being surrounded by a corresponding shell, and an operating table 2147 can be arranged inside the cab 21. To facilitate the operation and control of the operator, the operating table 2147 can be provided with a running push rod 2141, a brake push rod 2142, a display component 2143 (such as a display screen), a speed meter 2144, a wind pressure meter 2145, etc.

[0105] When driving the rail working vehicle 20 to carry the rail field working system 10 to the site or leave the site, the operator performs operation control on the operating console 2147 of the cab 24, for example, operating the operation push rod 2141 to advance or retreat to the site working point at a low speed, and pushing the brake push rod 2142 to stop the rail working vehicle 20 at the site working point. Then, the rail field working system 10 can be operated to prepare and operate the site work, such as normalizing treatment after rail welding; after completing the site work, the operator can pull back the brake push rod 2142 to cancel the brake, and drive the operation push rod 2141 to advance or retreat at a low speed to the next site working point.

[0106] In one embodiment, in order to overcome the problem that the cab 24 installed at one end cannot conveniently observe the road conditions at the other end (for example, the operator in the cab 24 at the head cannot observe the road conditions at the tail end due to being blocked by the huge rail field operation system 10 carried by it), an image sensor 27 (for example, a camera) is arranged at the tail of the frame 21 of the rail operation vehicle 20, and the image sensor 27 is coupled to the display component 2143 of the cab 24. When the rail operation vehicle 20 runs toward the tail direction of the frame 21 (for example, the positive direction of the x direction), the image sensor 27 collects image information of the road conditions ahead in real time, and the image collected by the image sensor 27 is transmitted to the display component 2143 for display; in this way, the operator in the cab 24 can observe the information of the road conditions ahead in real time through the image sensor 27, ensure the driving safety of the operation vehicle, and realize two-way driving without turning around, which not only improves the driving flexibility of the rail operation vehicle 20, but also helps to improve the operation efficiency.

[0107] It should be understood that the image sensor 27 is disposed at an end opposite to the cab 24 . For example, when the cab 24 is fixedly disposed on the rear end of the frame 21 , the image sensor 27 may be disposed at the head end of the frame 21 .

[0108] The following is further combined Figures 7 to 17 The rail field normalizing system 10 and the rail field normalizing assembly 1000 according to an embodiment of the present invention are described in detail by way of example. Figures 7 to 9 In the illustrated embodiment, the rail field operation assembly 1000 includes the rail operation vehicle 20 of any of the above embodiments, and also includes the rail field normalizing operation system 10 carried by the rail operation vehicle 20. The rail field operation assembly 1000 can provide power to the rail field normalizing operation system 10 and the rail operation vehicle 20 through a set of generator sets 12, so that it can not only provide power to the rail operation vehicle 20 through the generator set 12 when carrying the rail field normalizing operation system 10 to drive it to move on the rails, thereby realizing self-propelled walking, but also can provide the rail field normalizing operation system 10 with the generator set 12 during field operations. The electric energy required for field operations is very suitable for online or offline field operations.

[0109] In one embodiment, if Figures 7 to 15As shown, the rail field normalizing system 10 has a cabin 11 of a roughly box-like structure, for example, a container-like structure, so that it is convenient to carry the whole as a container. The cabin 11 can be formed by welding steel, and it has a large internal space for arranging various equipment required for completing the field normalizing operation. The chassis of the cabin 11 is used to carry these equipment, and it has a certain strength and rigidity, and can be specifically welded by profiles and steel plates. In order to facilitate the overall detachable installation and locking of the rail field normalizing system 10 on the frame 21, a plurality of container-type box corners 118 are welded on the cabin 11 corresponding to each locking assembly 212 on the frame 21.

[0110] The cabin 11 may be provided with Fig.14 The compartment 119 shown can roughly divide the interior of the cabin into an equipment room relatively far from the on-site operation point (e.g., the interior space near the front end) and an operation room relatively close to the on-site operation point (e.g., the interior space near the rear end). According to specific needs, more compartments can be set inside to divide the cabin 11 into more relatively independent spaces.

[0111] See also Figures 11 to 14 The cabin 11 is provided with a lighting window, for example, a lighting window 1131 (such as a lighting window 1131) provided on the side of the cabin 11 Fig.11 As shown), a lighting window 1132 (as shown) provided on the door 119 at the rear end of the cabin 11 Fig.13 As shown), a lighting window 1133 (as shown) provided on the interval 119 of the cabin 11 Fig.14 The cabin 11 may also be provided with a plurality of passage doors for workers to enter and exit, for example, one or more passage doors 1141 (such as Fig.11 As shown, a passage hatch 1142 (as shown in FIG. Fig.12 As shown in FIG. 1 , in order to facilitate access to the cab 24 from the cabin 11, a passage door 1143 (i.e., a passage door, such as Fig.14 The cabin 11 may also be provided with a plurality of shutters for facilitating ventilation, for example, shutters 1151 (such as Fig.11 As shown, the shutter 1152 (as shown in FIG. Fig.12 As shown, the shutter 1153 (as shown in FIG. 1 ) provided on the interval 119 of the cabin 11 Fig.14 as shown).

[0112] Continue as Figure 7 As shown, various equipment required for completing on-site normalizing heat treatment can be arranged in the cabin 11 (such as Figure 7The size of the cabin 11 can be designed according to the specific size of the rail vehicle 20, the number and size of the equipment it accommodates, etc.

[0113] Among them, the induction normalizing treatment device 30 performs electromagnetic induction heating on the welding head of the rail through an electromagnetic coil to achieve normalizing treatment. Therefore, the generator set 12 is required to generate electricity on site to provide the electricity required for induction heating. Of course, the generator set 12 can also provide the electricity required for the operation of other devices or equipment in the cabin 11 (such as the hydraulic pump station 17, etc.). Specifically, the generator set 12 can be a diesel generator set, so a corresponding diesel engine can be configured accordingly. Corresponding to the cooling needs of the generator set 12 and other equipment, a corresponding cooling unit 15 can also be configured accordingly, which is used to achieve cooling and heat dissipation of the running generator set 12, induction coil, etc.

[0114] Among them, the crane 16 is used to carry the induction normalizing treatment device 30. For example, when starting the on-site normalizing treatment, the crane 16 lifts the induction normalizing treatment device 30 in the cabin 11 to the rails outside the cabin 11, and even accurately lifts it to the position of the welding joint to be heat treated; after the normalizing treatment is completed, the induction normalizing treatment device 30 can be lifted back into the cabin 11.

[0115] The hydraulic pipeline of the hydraulic pump station 17 can be connected to the hydraulic pipeline of the induction normalizing device 30, so as to provide the required hydraulic pressure for at least the internal components (such as the coil opening and closing and translation device) of the induction normalizing device 30. It will be understood that the hydraulic pump station 17 can also provide hydraulic pressure for other hydraulically driven equipment (such as cylinders) such as the crane 16 and the main hatch opening and closing device 117 in the rail field normalizing operation system 10.

[0116] The normalizing management system 18 is used to manage the heat treatment process of the induction normalizing treatment device 30 and store corresponding normalizing treatment data, which can be implemented by a computer device with a human-computer interaction interface.

[0117] The air spray device 19 is used to spray air on the surface of the weld joint after normalizing the weld joint, so as to restore the surface hardness of the weld joint. As an example, the air spray device 19 is provided with an air compressor or the like to generate compressed air, and the compressed air is quickly sprayed on the surface of the weld joint of the rail 90 through a plurality of air spray nozzles (not shown in the figure) provided on the induction coil assembly 37.

[0118] Among them, a cooling fan can also be set at the front end of the rail field normalizing operation system 10. For example, the cooling fan can be a cooling fan on a diesel engine or a cooling fan of a chiller. The cooling fan can take away a large amount of heat generated in the direction of the induction normalizing treatment device 30, or even the heat generated inside the rail field normalizing operation system 10 in another direction in the form of airflow (for example, the airflow flows from the tail end to the front end), that is, the air inlet corresponds to the main cabin door 116, and the air outlet corresponds to the front end of the rail field normalizing operation system 10. Therefore, overheating caused by electromagnetic induction heating at the on-site operation point can be avoided. Specifically, the airflow can flow through the operation room, the shutter 1153 of the interval 119, the equipment room and the shutter 1152 in sequence, and can also take away a large amount of heat generated in the generator set 12 in the equipment room, which is conducive to improving the on-site operation environment.

[0119] The exhaust gas purification device 13 is arranged corresponding to the exhaust port of the diesel engine, and has the exhaust gas purification function, which is particularly helpful to improve the on-site working environment in, for example, a tunnel. Further, optionally, a silencer component such as a silencer cotton or a silencer that helps to reduce noise can be installed in the cavity of the exhaust pipe of the diesel engine to further improve the on-site working environment, protect the health of operators, and reduce noise pollution.

[0120] Continue as Figure 7 As shown, the induction normalizing treatment device 30, the crane 16, the hydraulic pump station 17, etc. are arranged in the working room, and the generator set 12 (including, for example, a diesel engine), the electrical control cabinet 14, the cooling unit 15, the normalizing management system 18, the air injection device 19, the cooling fan, the exhaust gas purification device 13, the silencer component, etc. are arranged in the equipment room.

[0121] Continue as Fig.10 As shown, the generator set 12 may be a diesel generator set, which includes a diesel engine 121, a generator 123, and an integrated base 129 with an inner cavity (i.e., a common base), wherein the base 129 is shared by the diesel engine 121 and the generator 123 and provides a common installation reference for them, and the inner cavity of the base 129 is used to hold the fuel of the diesel engine 121, that is, the diesel tank of the diesel engine 121 is realized through the base 129, so that the structural layout of the generator set 12 is more compact and very suitable for equipment rooms with small spaces. Specifically, elastic shock-absorbing pads 125 are respectively arranged between the diesel engine 121, the generator 123 and the base 129.

[0122] Specifically, a work lighting lamp 1101 can be provided at the rear end of the cabin 11, which is arranged at one end of the cabin 11 close to the on-site work point (such as the tail end), and can be used to provide lighting during on-site operations to improve working conditions such as in tunnels.

[0123] Specifically, a main hatch 116, i.e., a rear hatch, is provided at the rear end of the cabin 11. An opening and closing device 117 for driving the main hatch 116 to move may be provided corresponding to the main hatch 116. The opening and closing device 117 may be driven to move by the hydraulic pressure provided by the hydraulic pump station 17. The upper end of the main hatch 116 is hinged to the cabin 11; when the main hatch 116 is opened, the opening and closing device 117 may push the main hatch 116 to rotate around its upper end, thereby opening the main hatch 116, thereby facilitating the crane 16 to carry the induction normalizing treatment device 30; otherwise, the main hatch 116 may be closed.

[0124] In order to facilitate the control of the transportation of the induction normalizing treatment device 30, a corresponding auxiliary control panel 109 can be set at the lower part of at least one side of the outer side of the cabin 11 corresponding to the working room. The auxiliary control panel 109 can be provided with corresponding function buttons, which may correspond to buttons for controlling certain operations of the crane 16, buttons for controlling certain operations of the opening and closing device 117, etc. By operating the auxiliary control panel 109, the operator outside can also conveniently control the opening and closing device 117 to control the opening or closing of the main cabin door 116, and can also conveniently control certain operations of the crane 16, and even conveniently control the working lighting 1101.

[0125] In one embodiment, the main door 116 of the cabin 11 is located at the end of the operation room, and when the rail operation vehicle 20 stops to prepare for on-site operation, it can be conveniently opened or closed by the opening and closing device 117. The opening and closing device 117 is used to drive the main door 116 to move (for example, "open" or "close"); after the main door 116 is opened, the crane 16 can lift and move the induction normalizing device 30, so as to conveniently and accurately move the induction normalizing device 30 from the cabin 11 to the on-site operation point (for example, the work station aligned with the welding joint); after the normalizing treatment is completed, the crane 16 can lift and move the induction normalizing device 30, so as to move the induction normalizing device 30 from the on-site operation point to the cabin 11, and then close the main door 116.

[0126] In one embodiment, if Fig.15As shown, the opening and closing device 117 mainly includes a hydraulic cylinder 1171, a connecting rod 1172, a guide rod 1173, and an outer end 1174 of a piston rod 1175 corresponding to the hydraulic cylinder 1171 (i.e., the outer end 1174 of the piston rod 1175); wherein, the guide rod 1173, for example, can be fixed on the side wall of the cabin body 11 basically horizontally, for example, the guide rod 1173 is fixed on the side wall of the cabin body 11 basically horizontally, and the hydraulic cylinder 1171 is also basically arranged parallel to the guide rod 1173; the cylinder body of the hydraulic cylinder 1171 can be hinged to the guide rod 1173, so that the cylinder body is supported, and when the piston rod 1175 moves in the direction of the guide rod 1173, the cylinder body is allowed to rotate slightly relative to the guide rod 1173, so as to avoid excessive wear of the piston and / or deformation of the cylinder body and the piston rod 1175. The two ends of the connecting rod 1172 are respectively hinged on the outer end 1174 and the main cabin door 116. The outer end 1174 of the piston rod 1175 of the hydraulic cylinder 1171 has a guide block or is realized by a guide block. The guide block is sleeved on the guide rod 1173 and can slide back and forth along the guide rod 1173 in the horizontal direction. Specifically, the guide block can be split relative to the piston rod 1175, for example, fixed to the outer end 1174 by a detachable bolt connection, and the guide block relative to the piston rod 1175 can be fixed to the outer end 1174 by a detachable bolt connection. The piston rod 1175 can be an integrated type; when the hydraulic cylinder 1171 drives the piston rod 1175 to move, the outer end 1174 slides horizontally on the guide rod 1173, so that the piston rod 1175 of the hydraulic cylinder 1171 can maintain horizontal telescopic movement, and then the outer end 1174 transmits the force of the hydraulic cylinder 1171 to the main door 116 through the connecting rod 1172, which can conveniently complete the opening and closing of the main door 116 of the cabin body 11. For example, when the hydraulic cylinder 1171 pushes the outer end 1174 of the piston rod 1175 to the position as shown in FIG. Fig.15 When in the rearmost position shown, the main door 116 can be fully opened, which is very convenient for the crane 16 to operate; and the hydraulic cylinder 1171 can control the outer end 1174 of the piston rod 1175 to remain in this position so as to continuously keep the main door 116 in a fully open state.

[0127] The opening and closing device 117 of the above embodiment can be arranged on the side wall of the cabin 11, which is compact and small in size. In addition, the opening and closing device 117 has a simple overall structure and a reasonable installation position, so it occupies a small space and basically does not affect the working space of the crane 16.

[0128] In one embodiment, if Fig.17 As shown, in order to better meet the on-line or off-line on-site rail normalizing operations of railway lines under different environmental conditions, the crane 16 provided in the operation room can be specifically selected as a single-arm crane, and the front end of the arm of the single-arm crane 16 is connected to the rotatable hanger 361 (as shown in FIG. 1 ) of the induction normalizing treatment device 30 through a flexible chain (not shown in the figure). Fig.18 As shown in FIG. 1 , the induction normalizing device 30 can be hoisted by the corresponding oil cylinder of the crane 16. When the single-arm crane 16 hoists the induction normalizing device 30 with a single arm, it has better applicability than, for example, a double-arm design. This is because, when the normalizing operation object is a non-linear rail, for example, the height inconsistency between the left and right rails at the bend will cause the rail field operation assembly 1000 on the rail to tilt, and the z direction shown in the figure will not coincide with the gravity direction. When the crane lifts the induction normalizing treatment device 30, the flexible chain will not produce a certain angle with the z direction in the gravity direction. If the spacing between the booms of the double-arm crane is too small, the angle will cause the flexible chain for lifting the induction normalizing treatment device 30 to interfere with and collide with one of the two booms of the crane, which is very unfavorable for the retraction and extension of the induction normalizing treatment device 30, and is also not conducive to the precise alignment of the induction normalizing treatment device 30 relative to the welding joint station, and will also shorten the service life of the flexible chain; and if the spacing between the two arms is too large, it will also limit the range of movement of the double-arm crane in the y direction within the main cabin door 116. Therefore, the single-arm crane 16 occupies less space in the y direction, and its arm has a larger swing range in the main cabin door 116, and the operating range of the crane 16 is also larger; moreover, the single-arm crane 16 can be better suited for on-site operations of rails at curves, which not only increases the operating range, but also improves the flexibility and convenience of on-site operations, further enhancing the adaptability of the on-site normalizing operation system of the rails to different operating environments.

[0129] In one embodiment, continue as Fig.17As shown, the single-arm crane 16 can further be selectively a single-arm crane 16 with variable length, telescopic and slewing functions. The single-arm crane 16 includes a slewing device 163, a variable length cylinder 161, a telescopic cylinder 162, a basic arm 164, a telescopic arm 165, a column 166, a base 167, etc. The base 167 is fixed on the sliding plate 112; the rotating device 163 has a hydraulic turbine, which can drive the column 166 to rotate within a predetermined angle range in the xy plane through gear transmission; the column 166 is the main load-bearing structure, and the side surface of its lower end has a gear surface for engaging with the pinion of the rotating device 163; one end of the variable-length cylinder 161 is hinged to the lower end of the column 166, and the other end (corresponding to the piston end) is hinged to the basic arm 164 through a piston rod, so that a movable triangular structure is formed between the column 166, the basic arm 164 and the variable-length cylinder 161, and the lifting amplitude change function can be realized through the piston action of the variable-length cylinder 161; the telescopic arm 165 is telescopic relative to the basic arm 164 in its length direction, specifically, it is driven by the telescopic cylinder 162 arranged in its length direction to extend or retract relative to the fixed arm 164, therefore, the telescopic arm 165 and the basic arm 164 together form a telescopic arm body. The front end of the telescopic arm 165 is connected to the rotatable hanger 361 (such as Fig.18 shown).

[0130] Specifically, when performing the normalizing operation, the luffing cylinder 161 of the single-arm crane 16 extends to lift the induction normalizing device 30 away from the bottom plate of the cabin 11, the telescopic cylinder 162 of the single-arm crane 16 extends, and the telescopic arm 165 extends, thereby extending the induction normalizing device 30 out of the cabin 11, and then the luffing cylinder 161 is retracted to lower the induction normalizing device 30 until the induction normalizing device 30 reaches the corresponding rail joint normalizing station; conversely, the single-arm crane 16 can move the induction normalizing device 30 from the normalizing station to the bottom plate of the cabin 11. In the above operation process, the slewing device 163 can be used to slew the lifted induction normalizing device 30 as needed.

[0131] In one embodiment, continue as Fig.17As shown, considering that the rotation angle range and telescopic distance of the crane 16 are easily limited by the width of the main cabin door 116 and the length of the operation room, in order to increase the on-site normalizing operation range, a sliding mechanism 110 is further provided on the chassis of the cabin 11 for the crane 16, for example, a corresponding sliding mechanism 110 is provided on the chassis of the operation room close to the on-site operation point. The crane 16 is integrally mounted on the sliding mechanism 110, and through the movement of the sliding mechanism 110 relative to the chassis of the cabin 11 in the x direction, the boom of the crane 16 can be extended further outside the cabin 11, the column 166 is closer to the main cabin door 116, and the angle of rotation operation becomes larger, which effectively increases the on-site normalizing operation range, is more conducive to the on-site normalizing operation system of the rail in narrow spaces such as tunnels, and improves the adaptability of the on-site normalizing operation system of the rail to different operating environments; and the flexibility of the operation can be greatly improved. The sliding mechanism 110 can be implemented in the form of a sliding platform, and the crane 16 can be basically carried on the sliding platform as a whole. Specifically, the sliding mechanism 110 may include a sliding guide groove 111, a sliding plate 112, a vertical rolling bearing 113 installed on the sliding plate 112, a transverse rolling bearing 114 installed on the sliding plate 112, a sliding cylinder 115, etc. Among them, the column 166 of the single-arm crane 16 can be fixed on the sliding plate 112 by bolts; the sliding guide groove 111 is arranged in or on the bottom frame of the cabin 11 roughly along the x direction, and has a groove that is concave in the left and right directions, and the groove is surrounded by an upper groove wall, an inner groove wall and a lower groove wall on three sides; the sliding cylinder 115 is arranged in the bottom frame of the cabin 11, and its piston rod can act on one end face of the sliding plate 112. The sliding cylinder 115 can push the sliding plate 112 to move back and forth along the sliding guide groove 111 in the x direction to expand the working range; a plurality of rolling bearings are installed on the sliding plate 112, such as , four vertical rolling bearings 113 and four transverse rolling bearings 114; two of the four vertical rolling bearings 113 are respectively installed on the two side surfaces of the sliding plate 112 as a group, and the vertical rolling bearings 113 can roll along the upper groove wall or the lower groove wall of the sliding guide groove 111, and are limited by the upper groove wall and the lower groove wall of the sliding guide groove 111 in the z direction; two of the four transverse rolling bearings 114 are respectively installed on the two side surfaces of the sliding plate 112 as a group, and the transverse rolling bearings 114 can roll along the inner groove wall of the sliding guide groove 111, and are limited by the inner groove wall of the sliding guide groove 111 in the y direction.

[0132] Alternatively, if Fig.17As shown, in the front and rear directions of the sliding plate 112, the transverse rolling bearing 114 is installed close to the inner end relative to the vertical rolling bearing 113, that is, the vertical rolling bearing 113 is installed close to the outer end relative to the transverse rolling bearing 114; for example, for one side of the sliding plate 112, the two vertical rolling bearings 113 are respectively installed closer to the front and rear ends of the sliding plate 112, and the two transverse rolling bearings 114 are respectively installed closer to the middle position of the sliding plate 112; in this way, the vertical limiting function of the vertical rolling bearing 113 can be better exerted and the front and rear lever force generated when the arm of the crane 16 is extended outward can be better resisted.

[0133] When normalizing is performed, the induction normalizing device 30 is lifted off the bottom plate of the cabin 11 by the single-arm crane 16, and the sliding cylinder 115 is operated to move the sliding plate 112 to a predetermined position in the x direction and lock it. During the movement, considering the heavy weight of the lifted induction normalizing device 30 and the displacement of the center of the crane 16 and the induction normalizing device 30 in the x direction, a pair of vertical rolling bearings 113 in the direction close to the on-site operation will be pressed down on the lower groove wall of the sliding guide groove 111 and roll along the lower groove wall, and a pair of vertical rolling bearings 113 in the direction away from the on-site operation will be pressed down on the upper groove wall of the sliding guide groove 111 and roll along the upper groove wall, thereby preventing the sliding plate 112 from swinging in the xz plane during the sliding process; at the same time, the transverse rolling bearing 114 limited in the y direction by the inner groove wall of the sliding guide groove 111 The sliding plate 112 can be prevented from swinging in the xy plane (even if the sliding plate 112 carries a very heavy crane 16). Therefore, the sliding plate 112 and the crane 16 carried by it move linearly in the x direction, avoiding excessive up-and-down and / or left-and-right swings. Moreover, it can be realized by 8 bearings, which is low in cost.

[0134] It will be understood that the vertical rolling bearings 113 and the lateral rolling bearings 114 are not limited to four, and for example, six or more vertical rolling bearings 113 and lateral rolling bearings 114 may be arranged as needed.

[0135] It will be understood that the specific implementation of the sliding mechanism 110 is not limited to the above embodiment. For example, in another variant structure, the sliding plate 112 can be made into a groove with both sides folded inward to serve as a sliding guide groove, and the bearing is fixedly installed and positioned in the groove. Through the bearing, the sliding plate 112 can slide back and forth on the chassis. In another variant structure, the rolling bearing can be arranged on both sides of the chassis, but it may be necessary to install more rolling bearings to meet the working condition requirements of the crane. Accordingly, the sliding plate 112 may not be installed with bearings.

[0136] The above examples mainly illustrate the rail field normalizing system of the present invention and the rail field normalizing assembly using the rail field normalizing system. Although only some of the embodiments of the present invention are described, it should be understood by those skilled in the art that the present invention can be implemented in many other forms without departing from its subject matter and scope. Therefore, the examples and embodiments shown are regarded as illustrative rather than restrictive, and the present invention may cover various modifications and substitutions without departing from the spirit and scope of the present invention as defined in the appended claims.
