Description

TECHNICAL FIELD

[0001] The present application relates to a track reinforcement vehicle, in particular to an induction heating system of a track reinforcement vehicle and a reversing method thereof, for track heating of the track reinforcement vehicle before paint spraying. BACKGROUND

[0002] The track reinforcement vehicle is a high-end railway maintenance engineering vehicle specially used for preventive repair and reinforcement of railway tracks. Its core technology is based on laser cladding technology, which melts a layer of extremely hard, wear-resistant and corrosion-resistant alloy on the track surface through preheating and laser cladding.

[0003] The track reinforcement vehicle needs to heat the track before paint spraying, which has two effects: 1. Improve the adhesion of the paint on the track. The paint has a certain fluidity when it is sprayed out, which will flow to both sides of the track, causing the track tread to be too thin and affecting the reinforcement effect. Heating the track to a certain temperature before spraying can make the paint evaporate enough solution instantly when sprayed onto the track surface, thereby inhibiting its fluidity and ensuring the sufficient thickness of the paint. 2. A certain high temperature track reduces the energy of the laser heating the track to raise the temperature, thereby improving the utilization rate of laser energy.

[0004] The track reinforcement vehicle drives on the track while working, and when heating the track, the heating surface and the heated surface must maintain a certain distance. If the distance is too close, the heating surface and the track surface may be damaged, and if the distance is too far, the desired heating effect cannot be achieved. Therefore, the application published as CN117842116A discloses a self-adaptive positioning mechanism of a track reinforcement vehicle traveling along the track, which includes a longitudinal cylinder, a transverse cylinder, a bottom plate, an accessory mounting plate and a positioning wheel device, for ensuring that the distance between the heating head mechanism mounted on the accessory mounting plate and the track remains unchanged.

[0005] Traffic tracks are usually designed as double tracks. When the track reinforcement vehicle completes the work on one side of the track, the heating head mechanism needs to be moved and reversed to transfer to the other side of the parallel track for continuous work. The actions to be completed include translation of the heating head mechanism, 180° turning, and at the same time, maintaining a certain distance from the opposite track. Due to the large size and heavy weight of the entire heating head mechanism, the entire reversing process cannot be efficiently and accurately completed by manpower alone. SUMMARY

[0012] The preferred technical scheme adopted by the present application to solve the above technical problems is that the translation mechanism comprises a supporting frame, a lifting lead screw and a lifting bottom plate to constitute the lifting device.

DETAILED DESCRIPTION

[0022] To make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0023] As Figure 1 and Figure 9 The track reinforcement vehicle induction heating system 100 provided by the present embodiment is installed on the track reinforcement vehicle as a whole, and includes an induction heating host 10, two groups of symmetrically arranged adaptive positioning wheel mechanisms 20, a heating head mechanism 30, a translation mechanism mounting bracket 40, and a translation mechanism 50.

[0024] The two groups of adaptive positioning wheel mechanisms 20 are arranged on parallel two-side tracks r, wherein the left adaptive positioning wheel mechanism 20a is arranged on the left track r1, and the right adaptive positioning wheel mechanism 20b is arranged on the right track r2. For the structure of the adaptive positioning wheel mechanism 20, the connection relationship with the track, the working principle, etc., refer to the invention patent application text with the application publication number CN117842116A, which will not be repeated here.

[0025] The heating head mechanism 30 includes a heating head 31, and the heating head mechanism 30 is installed on the heating head mechanism mounting plate 21 of any one group of adaptive positioning wheel mechanisms 20, for keeping the working distance L between the heating head 31 and the surface of the track r.

[0026] Specifically, as Figure 2As shown, the longitudinal section of the heating head 31 is in inverted L shape to cover the upper surface and inner surface of the track. The working distance L between the inner surface (heating surface j1) of the heating head 31 and the outer surface (heated surface j2) of the track r should be kept at 8mm≤L≤10mm. If the distance is too close, the heating surface and the heated surface j2 can be damaged, and if the distance is too far, the desired heating effect cannot be achieved. The self-adaptive positioning wheel mechanism 20 keeps the distance to the track r unchanged in the vertical and horizontal directions when the track reinforcement vehicle moves, thereby ensuring that the working distance between the heating surface j1 of the heating head 31 and the heated surface j2 of the track remains relatively constant.

[0027] As shown in Figure 1 and Figure 9 , the induction heating host 10 is installed on the floor g of the carriage of the track reinforcement vehicle, and the heating head 31 is connected to the heating head 31 through a flexible cable p to supply power to the heating head 31.

[0028] The translation mechanism mounting frame 40 is hung on the underside of the floor g of the track reinforcement vehicle, and the translation mechanism 50 is arranged on the translation mechanism mounting frame 40 and can translate left and right on the translation mechanism mounting frame 40. The length of the translation mechanism mounting frame 40 at least spans two self-adaptive positioning wheel mechanisms 20, and the translation mechanism 50 can transfer the heating head mechanism 30 from one set of self-adaptive positioning wheel mechanisms 20 to another set of self-adaptive positioning wheel mechanisms 20 through the translation mechanism mounting frame 40, and the heating head 31 can be turned 180° for maintaining the working distance L between the heating head 31 and the surface of the track r.

[0029] A quick connection device is provided between the translation mechanism 50 and the heating head mechanism 30 to connect the heating head mechanism 30 to the translation mechanism 50. A lifting device is provided on the translation mechanism 50 to adjust the height position of the heating head mechanism 30. A rotation device is provided on the heating head mechanism 30 to enable the heating head 31 to be turned 180°.

[0030] Specifically, first, the rotation device of the heating head mechanism 30 is described. As shown in Figures 2 to 4 , the heating head mechanism 30 includes a connecting plate 32 and a rotating sliding table 33 in addition to the heating head 31 to constitute the rotation device. The connecting plate 32 is fixed with the heating head mechanism mounting plate 21 to mount the heating head mechanism 30 on the self-adaptive positioning wheel mechanism 20. The rotating sliding table 33 is fixed with the heating head 31. The rotating sliding table 33 is rotatably mounted on the underside of the connecting plate 32, and the rotating sliding table 33 is rotated 180° relative to the connecting plate 32 to cause the heating head 31 to be turned 180°.

[0031] In the embodiment, the connecting plate 32 has a rotating hole x1, the upper side of the rotating slide 33 is provided with a rotating disc x2, the rotating disc x2 of the rotating slide 33 is rotatably arranged at the lower side of the rotating hole x1, the heating head 31 is fixed at the lower side of the rotating slide 33, so that when the rotating slide 33 rotates 180° relative to the connecting plate 32, the heating head 31 is turned 180°.

[0032] Next, the quick connecting device between the translation mechanism 50 and the heating head mechanism 30 is described. As shown in Figure 3 、 Figure 6 and Figure 8 , the front side and the rear side of the connecting plate 32 of the heating head mechanism 30 are each provided with a hook 34. The hook 34 is downwardly directed and arranged at the end of a horizontally extending hook arm 34a.

[0033] As shown in Figure 5 , the front side and the rear side of the translation mechanism 50 are each provided with a quick clamp 51, and the quick clamp 51 and the hook 34 constitute the quick connecting device. The quick clamp 51 includes a handle 52 and a hook ring 53. The handle 52 is turned in a first direction to unlock the hook ring 53, and the hook ring 53 can hook the hook 34. The handle 52 is turned in the opposite direction of the first direction to lock the hook ring 53, and the hook 34 is locked on the hook ring 53.

[0034] In the embodiment, as shown in Figures 6 to 8 , the handle 52 is turned downward to unlock the hook ring 53, at this time, the hook ring 53 can be pulled upward and outward, and then hooked on the hook 34 inward and downward. Subsequently, the handle 52 is turned upward to lock the hook ring 53, so that the hook ring 53 is in a vertically downward position, and the hook 34 is locked on the hook ring 53, at this time, the heating head mechanism 30 is connected to the translation mechanism 50 As shown in Figure 3 and Figure 4 , the left and right sides of the connecting plate 32 are provided with a positioning pin d1 and a first bolt hole d2, and the heating head mechanism mounting plate 21 is provided with a pin hole d3 and a second bolt hole d4. The positioning pin d1 penetrates the pin hole d3, and the bolt d5 penetrates the first bolt hole d2 and the second bolt hole d4, so as to mount and fix the connecting plate 32 with the heating head mechanism mounting plate 21, that is, to fix the heating head mechanism 30 to the self-adaptive positioning wheel mechanism 20.

[0035] In other embodiments, the heating head mechanism 30 and the adaptive positioning wheel mechanism 20 can also adopt other detachable fixing modes, for example, only bolt screwing fixation, or lock catch structure fixation, etc. In the embodiment, the two are first positioned by the positioning pin d1 and the pin hole d3, and then fastened by the bolt d5, which not only can ensure that the heating head mechanism 30 with a larger weight is reliably and stably fixed to the adaptive positioning wheel mechanism 20, and is not easy to shake during the process of driving and working, causing the distance between the heating surface j1 and the heated surface j2 to change, but also is more convenient and efficient during assembly.

[0036] Next, the lifting device of the translation mechanism 50 is described. As shown in Figures 5 to 7 , the translation mechanism 50 includes a support frame 54, a lifting lead screw 55, and a lifting bottom plate 56 to constitute the lifting device. The support frame 54 is a rectangular frame structure, and the lifting bottom plate 56 is arranged below the support frame 54 and is connected to the bottom frame 54a of the support frame 54 through the lifting lead screw 55.

[0037] The top frame 54b of the support frame 54 is sleeved on the horizontal rail 41 of the translation mechanism mounting rack 40 to connect the translation mechanism mounting rack 40 and can translate left and right along the horizontal rail 41 of the translation mechanism mounting rack 40. The quick connection device is arranged on the lifting bottom plate 56, and in the embodiment, two quick clamps 51 are arranged at the front and rear ends of the lifting bottom plate 56, respectively.

[0038] The lifting lead screw 55 is rotated to make the lifting bottom plate 56 rise or fall relative to the support frame 54 to adjust the height position of the heating head mechanism 30. Specifically, in the embodiment, the top end of the lifting lead screw 55 is arranged in the form of a lifting turntable 55a and is fixed on the upper side of the bottom frame 54a of the support frame 54. The lower end of the lifting lead screw 55 is connected to the lifting bottom plate 56, so that rotating the lifting turntable 55a can make the lifting bottom plate 56 rise or fall relative to the bottom frame 54a of the support frame 54. The design of the lifting turntable 55a can facilitate grasping and twisting.

[0039] Further, a pair of vertical rails 57 is arranged between the lifting bottom plate 56 and the support frame 54, the lower end of the pair of vertical rails 57 is fixed on the lifting bottom plate 56, is sleeved on the bottom frame 54a of the support frame 54, and the lifting lead screw 55 is located between the pair of vertical rails 57. The lifting lead screw 55 is rotated to make the lifting bottom plate 56 rise or fall along the vertical rails 57, thereby playing a guiding role while ensuring the stability of the lifting bottom plate 56 rising or falling, which is particularly important when the lifting bottom plate 56 is connected and bears the weight of the heating head mechanism 30.

[0040] As shown in Figure 1 and Figure 9As shown, the translation mechanism mounting frame 40 includes two left and right connecting frames 42 and a horizontal rail 41 spanning between the two connecting frames 42. The connecting frames 42 are used to connect the track reinforcement vehicle, in this embodiment, the connecting frames 42 are suspended on the underside of the floor g of the track reinforcement vehicle. The translation mechanism 50 is suspended on the horizontal rail 41 and can translate left and right along the horizontal rail 41.

[0041] Preferably, in this embodiment, the induction heating host 10 is a super-audio frequency induction heating host, which is installed on the floor g inside the car of the track reinforcement vehicle and connected to the heating head 31 through a flexible cable p. The super-audio frequency induction heating host can heat the track r to the required temperature in a short enough time, thereby ensuring the high efficiency of the surface preheating treatment of the track r and laying a solid foundation for the subsequent spraying. The connection through the flexible cable p can ensure that the heating head mechanism 30 is not hindered during reversing and smoothly translates and turns.

[0042] In addition, as shown in Figures 1 to 3 , Figure 9 The heating head mechanism 30 also includes a transformer 35. The induction heating host 10 is connected to the transformer 35 through the flexible cable p, and the transformer 35 is connected to the heating head 31. The transformer 35 steps down the rated voltage of the induction heating host 10 to a safe voltage, which is at least less than 24V, to supply the heating head 31.

[0043] The present application does not necessarily use a transformer 35. The transformer 35 is used in this embodiment to step down the voltage and increase the current, making the preheating treatment process safer. The rated power of the super-audio frequency induction heating host is 60kW. If the transformer is not selected, based on the power loss, the heating head 31 cannot efficiently exert the power of 60KW, and it is not safe for the carrier to carry high voltage. The use of the transformer 35 not only compensates for the voltage drop of the flexible cable p, but also reduces the output voltage of the heating head 31 to below 24V, ensuring the safety of the workers (especially when reversing the heating head mechanism 30).

[0044] The following describes the reversing method of the induction heating system of the track reinforcement vehicle provided by the present application, which further dynamically and concretely explains the technical advantages of the induction heating system of the track reinforcement vehicle in reversing.

[0045] As shown in Figure 1 Suppose that in the initial state, the heating head mechanism 30 is fixedly connected to the heating head mechanism mounting plate 21 of the right adaptive positioning wheel mechanism 20b, and the work on the right track r2 has been completed, and it is necessary to reverse the heating head mechanism 30 to the heating head mechanism mounting plate 21 of the left adaptive positioning wheel mechanism 20a. It specifically includes the following steps: Step 1: Move the translation mechanism 50 above the heating head mechanism 30.

[0046] Step 2: Turn the lifting device to lower the translation mechanism 50 and make it fit with the heating head mechanism 30.

[0047] Step 2 further comprises the following steps: Step 2-1: Turn the lifting screw 55 to lower the lifting base plate 56 of the translation mechanism 50 and make the lower surface of the lifting base plate 56 fit with the upper surface of the connecting plate 32 of the heating head mechanism 30.

[0048] Step 3: Connect the heating head mechanism 30 to the translation mechanism 50 through the quick connection device.

[0049] Step 3 further comprises the following steps: Step 3-1: Turn the handle 52 downward to unlock the hanging ring 53.

[0050] Step 3-2: Pull the hanging ring 53 outward and upward, and hook it inward and downward to the hook 34.

[0051] Step 3-3: Turn the handle 52 upward to lock the hanging ring 53, and the hook 34 is locked on the hanging ring 53, and the heating head mechanism 30 is connected to the translation mechanism 50.

[0052] Step 4: Disconnect the heating head mechanism 30 from the same side adaptive positioning wheel mechanism 20 (in this embodiment, the right adaptive positioning wheel mechanism 20b).

[0053] Step 4 further comprises the following steps: Step 4-1: Loosen the bolt d5 between the connecting plate 32 and the heating head mechanism mounting plate 21 to disconnect the heating head mechanism 30 from the same side adaptive positioning wheel mechanism 20 (in this embodiment, the right adaptive positioning wheel mechanism 20b).

[0054] Step 5: Turn the lifting device to lift the heating head mechanism 30 with the translation mechanism 50.

[0055] Step 5 further comprises the following steps: Step 5-1: Turn the lifting screw 55 to lift the lifting base plate 56 of the translation mechanism 50 to lift the heating head mechanism 30 with the translation mechanism 50.

[0056] Step 6: Translate the translation mechanism 50 along the translation mechanism mounting frame 40 to translate the heating head mechanism 30 above the target track r on the opposite side (in this embodiment, the left track r1).

[0057] In this step 6, the translation mechanism 50 is translated along the horizontal track 41 of the translation mechanism mounting frame 40 from the right side to the left side.

[0058] Step 7: Turn the rotating device to turn the heating head 180°.

[0059] This step 7 further includes the following steps: Step 7-1: Rotate the rotating slide 33 of the heating head mechanism 30 to rotate the heating head 31 by 180°.

[0060] Step 8: Rotate the lifting device to make the translation mechanism 50 drive the heating head mechanism 30 to descend and be connected and fixed with the adaptive positioning wheel mechanism 20 on the opposite side (in this embodiment, the left adaptive positioning wheel mechanism 20a).

[0061] This step 8 further includes the following steps: Step 8-1: Rotate the lifting screw 55 to make the lifting bottom plate 56 of the translation mechanism 50 descend, so that the translation mechanism 50 drives the heating head mechanism 30 to descend.

[0062] Step 8-2: The positioning pin d1 of the connecting plate 32 of the heating head mechanism 30 penetrates the pin hole d3 of the heating head mechanism mounting plate 21 of the adaptive positioning wheel mechanism 20.

[0063] Step 8-3: Bolt d5 is passed through the first bolt hole d2 and the second bolt hole d4 to install and fix the connecting plate 32 with the heating head mechanism mounting plate 21.

[0064] Step 9: Release the quick connecting device, reset the lifting device, and move the translation mechanism 50 to the safe position of the translation mechanism mounting frame 40.

[0065] This step 9 further includes the following steps: Step 9-1: The handle 52 is rotated downward to unlock the hanging ring 53, and the hanging ring 53 is pulled upward outward to make the translation mechanism 50 and the heating head mechanism 30 disengage.

[0066] Step 9-2: Rotate the lifting screw 55 to make the lifting bottom plate 56 of the translation mechanism 50 ascend and reset.

[0067] Step 9-3: The translation mechanism 50 moves to the middle position of the horizontal rail 41 of the translation mechanism mounting frame 40.

[0068] It should be noted that, since the heating head mechanism 30 moves with the adaptive positioning wheel mechanism 20, in order to prevent the translation mechanism 50 from colliding with the heating head mechanism 30 when the translation mechanism 50 is not performing the translation operation, the translation mechanism 50 needs to stay in the middle position of the horizontal rail 41 of the translation mechanism mounting frame 40 as a safe position. Therefore, the position of each device of the induction heating system 100 of the track reinforcement vehicle after the reversing operation is completed is as shown in Figure 9 .

[0069] In summary, the induction heating system of the track reinforcement vehicle and the reversing method provided by the present application have at least the following technical advantages: 1. The induction heating main machine is connected with the heating head to realize the preheating treatment of the track surface before spraying, so as to improve the adhesion of the coating on the track and improve the utilization rate of laser energy. Further, the ultrasonic frequency induction heating main machine can heat the track to the required temperature in a short time, ensuring the high efficiency of the track surface preheating treatment.

[0070] 2. By means of the translation mechanism mounting frame, the translation mechanism, and the rotating device on the heating head mechanism, the heating head mechanism is transferred from one side of the adaptive positioning wheel mechanism to the other side of the adaptive positioning wheel mechanism, that is, the heated surface of one side of the track is changed to the heated surface of the other side of the track, so as to complete the surface preheating treatment of the double-sided track.

[0071] 3. Through the coordinated action of the quick connecting device, the lifting device, the rotating device, and the translation device, the operator can save labor, quickly and accurately complete the reversing of the heating head mechanism with certain weight and volume, and ensure that after the heating head mechanism is reversed to the target track on the other side, the heating surface of the heating head and the heated surface of the track still maintain a suitable working distance, so as to ensure the normal operation of the preheating treatment of the double-sided track surface.
