Description

Technical Field

[0001] This application relates to the technical field of heating devices for rail welding machines, and in particular to a heating device for a multi-functional rail welding machine. Background Technology

[0002] Traditional rail welding machines are limited by their structure, making them unsuitable for welding rails at turnout locations or in narrow areas. Therefore, welding machines capable of narrow clamping have emerged in the industry. By placing the rail clamping component at the bottom of the welding machine and narrowing its structure, it can be inserted into the turnout location of the track to clamp the rail.

[0003] Heating devices are used to heat the joint ends of two rails to the required welding temperature during rail welding. However, due to adjustments in the structure of existing multi-functional rail welding machines, traditional heating devices can no longer meet the heating needs of these machines when welding rails at track switches or in narrow areas. Therefore, designing a heating device that can adapt to the new multi-functional rail welding machine is particularly important. Utility Model Content

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. The described embodiments are merely possible technical implementations of this utility model, but are not limited thereto. Those skilled in the art can certainly combine the embodiments of this utility model to obtain other embodiments without creative effort, which are also within the protection scope of this utility model.

[0031] This application discloses a heating device for a multi-functional rail welding machine. (Refer to...) Figure 1 and Figure 2The system includes a swaying frame 1, a horizontal drive mechanism 2, a heating module 3, and a vertical drive mechanism 4. The swaying frame 1 is horizontally slidably mounted on the rail welding machine base. The horizontal drive mechanism 2 is connected to the swaying frame 1 and can drive the swaying frame 1 to move horizontally. The heating module 3 is vertically slidably mounted on the swaying frame and is used to heat the rail. The heating module 3 is horizontally fixed relative to the swaying frame 1. The vertical drive mechanism 4 is horizontally slidably mounted on the rail welding machine base and is used to drive the heating module 3 to move vertically. This structure allows the heating module 3 to be flexibly adjusted in both horizontal and vertical directions. The heating module 3 includes a first heating plate 31, a second heating plate 32, and a splitting mechanism 5 for driving the first heating plate 31 and the second heating plate 32 to slide in a direction that moves closer or further apart from each other. A heating area 33 for the rail to pass through is formed between the first heating plate 31 and the second heating plate 32. The splitting mechanism 5 brings the first heating plate 31 and the second heating plate 32 closer together, so that the rail is located in the heating area 33 formed by the first heating plate 31 and the second heating plate 32, so that the heating device can adapt to and meet the rail heating needs of existing multi-functional rail welding machines at different welding positions.

[0032] Reference Figure 3 Specifically, the horizontal drive mechanism 2 includes a first sleeve 21, a second sleeve 22, a first guide rod 23, a second guide rod 24, and a power assembly 25. The first sleeve 21 and the second sleeve 22 are fixedly mounted on the rail welding machine. The first guide rod 23 slides through the first sleeve 21 and is fixedly connected to the fire-swinging frame 1. The second guide rod 24 slides through the second sleeve 22 and is also fixedly connected to the fire-swinging frame 1. The first guide rod 23 and the second guide rod 24 are parallel in length and symmetrically arranged on both sides of the fire-swinging frame 1. The first guide rod 23 and the second guide rod 24 are fixedly connected to the fire-swinging frame 1 by bolts, facilitating installation and disassembly.

[0033] Reference Figure 1 and Figure 3The power assembly 25 includes a transmission rod 251, a first gear 252, a second gear 253, and a motor 254. The transmission rod 251 is rotatably mounted on the rail welding machine. The first gear 252 and the second gear 253 are respectively located at both ends of the transmission rod 251 and are coaxially fixedly connected to it. The side walls of the first guide rod 23 and the second guide rod 24 are provided with toothed grooves. The side walls of the first sleeve 21 and the second sleeve 22 are both provided with notches. The first gear 252 is located at the notch of the first sleeve 21 and meshes with the toothed groove on the first guide rod 23. The second gear 253 is located at the notch of the second sleeve 22 and meshes with the toothed groove on the second guide rod 24. The motor 254 is fixedly mounted on the rail welding machine. A transmission gear 255 is coaxially fixedly mounted on the output shaft of the motor 254, and the transmission gear 255 meshes with the first gear 252. Motor 254 drives transmission gear 255 to rotate, and transmission gear 255 drives first gear 252 to rotate. First gear 252 meshes with the tooth groove on first guide rod 23, causing first guide rod 23 to slide in first sleeve 21. At the same time, first gear 252 drives second gear 253 to rotate through transmission rod 251. Second gear 253 meshes with the tooth groove on second guide rod 24, causing second guide rod 24 to slide in second sleeve 22. This achieves synchronous movement of first guide rod 23 and second guide rod 24, thereby precisely controlling the stroke on both sides of the fire-swinging frame 1 and the horizontal position of the fire-swinging frame 1, ensuring the stability of the fire-swinging frame 1 during movement.

[0034] Reference Figure 1 and Figure 2 Specifically, the longitudinal drive mechanism 4 includes a lifting block 41, an adjusting screw 42, and a handle 43. The lifting block 41 is slidably mounted on the fire-spreading frame 1 in the vertical direction. The adjusting screw 42 is rotatably mounted on the fire-spreading frame 1 and threadedly engaged with the lifting block 41. The handle 43 is rotatably mounted on the fire-spreading frame 1 and drives the adjusting screw 42 to rotate via gear transmission. The heating module 3 is mounted on the lifting block 41. When the operator rotates the handle 43, the handle 43 drives the adjusting screw 42 to rotate. Since the adjusting screw 42 is threadedly engaged with the lifting block 41, the rotation of the adjusting screw 42 causes the lifting block 41 to slide vertically on the fire-spreading frame 1, thereby moving the heating module 3 vertically and adjusting the height of the heating module 3.

[0035] In addition, other methods can be used as the horizontal drive mechanism 2 that drives the fire stand 1 to move horizontally in the horizontal direction, and the longitudinal drive mechanism 4 that drives the heating module 3 to move vertically in the vertical direction. For example, pneumatic cylinders, hydraulic cylinders, electric push rods, motor 254 with gear and rack transmission, motor 254 with screw transmission, etc.

[0036] Reference Figure 1 and Figure 2Both the first heating plate 31 and the second heating plate 32 are embedded with gas pipes 34, which are used to connect to gas delivery equipment. Several gas outlets (not shown in the figure) are opened on the end faces of the first heating plate 31 and the second heating plate 32 that are close to each other. After the rails are joined, the longitudinal drive mechanism 4 drives the heating module 3 to slide down as a whole, so that the rails are positioned between the first heating plate 31 and the second heating plate 32. The separating and joining mechanism 5 brings the first heating plate 31 and the second heating plate 32 closer together, so that the rails are located within the heating area 33 formed by the first heating plate 31 and the second heating plate 32. Gas is delivered into the gas pipes 34 through the gas delivery equipment. When the gas is delivered to the gas outlet through the gas pipes 34, it is ignited at the gas outlet, achieving comprehensive heating of the rail welding position and improving the heating effect of the rails.

[0037] Reference Figure 1 and Figure 2 The first heating plate 31 and the second heating plate 32 are also embedded with water-cooled pipes 35 and air-cooled pipes 36. The water-cooled pipes 35 connect to cooling water delivery equipment, and the air-cooled pipes 36 connect to cold air delivery equipment. At the ends of the first heating plate 31 and the second heating plate 32 that are close to each other, there are several cooling water outlets connected to the water-cooled pipes 35 and cold air outlets connected to the air-cooled pipes 36 (not shown in the figure). The cooling water delivery equipment can be a water tank and a water pump, and the cold air delivery equipment can be an air compressor. The water-cooled pipes 35 can deliver cooling water to the cooling water outlets for water-cooling cooling of the weld joint; the air-cooled pipes 36 can deliver cold air to the cold air outlets for air-cooling cooling of the weld joint. Thus, according to construction needs, a suitable cooling method can be selected, achieving comprehensive and efficient cooling of the rail weld joint and ensuring welding quality.

[0038] Reference Figure 1 and Figure 2 The splitting and joining mechanism 5 includes a housing 51, a first slider 52, a second slider 53, and a transmission assembly 54. The housing 51 is fixedly mounted on the lifting block 41 by bolts. The first slider 52 and the second slider 53 are slidably mounted inside the housing 51. A guide rod is fixedly mounted inside the housing 51 along the length direction of the housing 51. The first slider 52 and the second slider 53 are both slidably mounted on the guide rod. A connection port is opened at the bottom of the housing 51. The first slider 52 and the second slider 53 are both located at the connection port. A first mounting plate 521 is fixedly mounted on the first slider 52, and a second mounting plate 531 is fixedly mounted on the second slider 53. The first mounting plate 521 is fixedly connected to the first heating plate 31 by bolts, and the second mounting plate 531 is fixedly connected to the second heating plate 32 by bolts.

[0039] Reference Figure 2The transmission assembly 54 includes a connecting rod 541, a first connecting rod 542, a second connecting rod 543, and a push-pull rod 544. The connecting rod 541 is rotatably disposed within the housing 51 and located between the first slider 52 and the second slider 53. One end of the first connecting rod 542 is hinged to the first slider 52, and the other end is hinged to the connecting rod 541. One end of the second connecting rod 543 is hinged to the second slider 53, and the other end is hinged to the connecting rod 541. The push-pull rod 544 slidably passes through the housing 51 and is fixedly connected to the first slider 52. When the push-pull rod 544 is pulled or pushed, it causes the first slider 52 to slide within the housing 51. The first slider 52 drives the connecting rod 541 to rotate via the first connecting rod 542, and the connecting rod 541 then drives the second slider 53 to slide via the second connecting rod 543, thereby enabling the first heating plate 31 and the second heating plate 32 to slide in directions that bring them closer together or further apart. In addition, a push-pull rod 544 is also fixedly installed on the second slider 53. The push-pull rod 544 on the second slider 53 is also slidably inserted through the housing 51. The push-pull rod 544 on the first slider 52 or the second slider 53 can drive the first slider 52 and the second slider 53 to slide synchronously in the direction of approaching or moving away from each other, which is convenient for the operator to operate.

[0040] Reference Figure 4 A locking block 511 is fixedly installed on the housing 51. A push-pull rod 544 slides through the locking block 511. A locking rod 5441 is fixedly installed on the side wall of the push-pull rod 544. The side wall of the locking block 511 has an L-shaped slot 5111 for the locking rod 5441 to engage. When the first heating plate 31 and the second heating plate 32 move to the appropriate position and are in contact with each other, the locking rod 5441 is located in the slot 5111. By rotating the pull rod, the pull rod can be slidably locked, preventing the first heating plate 31 and the second heating plate 32 from moving relative to each other during the heating process, which would affect the heating quality of the rail.

[0041] In addition, other power sources can be used as the disengagement mechanism 5 for driving the first heating plate 31 and the second heating plate 32 to slide. For example, a two-way cylinder drive, a two-way screw drive with motor 254, or a motor 254 drive with gear and rack, etc., are all acceptable as long as they can drive the first heating plate 31 and the second heating plate 32 to slide.

[0042] The implementation principle of a heating device for a multi-functional rail welding machine according to an embodiment of this application is as follows: The horizontal drive mechanism 2 drives the swing frame 1 to move horizontally, and the longitudinal drive mechanism 4 drives the heating module 3 to move vertically on the swing frame 1. The splitting and joining mechanism 5 makes the first heating plate 31 and the second heating plate 32 move closer to each other, so that the rail is located in the heating area 33 formed by the first heating plate 31 and the second heating plate 32. Thus, the position of the heating module 3 can be adjusted so that the heating device can adapt to and meet the rail heating needs of existing multi-functional rail welding machines at different welding positions.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
