Description

Technical Field

[0001] The utility model relates to the technical field of flash welding machines, in particular to an embedded control platform, a welding machine head thereof and a rail flash welding machine. Background Art

[0002] As an important component in railway lines, turnouts play a crucial role in railway transportation safety. Since the major speed increase of railways in the 1990s, seamless track technology has been widely adopted in China's railways. Among them, flash welding and gas pressure welding technologies are mainly used for the welding of main line rails. Due to structural and material limitations of railway turnouts, the connection between various components and the connection with the main line still adopt thermite welding or fishplate bolt connection methods. The quality of thermite welding is unstable, the joint strength is low, and defects such as pores and slag inclusions are likely to occur, seriously affecting the service life of turnouts. Currently, it has become one of the weakest links in line quality and operation safety.

[0003] Flash welding is one of the most stable and widely used rail welding technologies. Its principle is to use resistance heating to melt the metal at the end of the joint, and then connect the two rails into a whole by applying pressure for upsetting. For example, a suspended rail flash welding and induction heat treatment integrated machine disclosed in CN116551137A includes a welding device and an induction heat treatment machine. The welding device includes a static frame clamping mechanism, a moving frame clamping mechanism, a pressure maintaining and burr removing mechanism, a burr removing knife assembly and a upsetting guiding shaft mechanism. The moving frame clamping mechanism and the static frame clamping mechanism are hoisted and suspended through a suspension mechanism. The A central axis of the moving frame clamping mechanism and the B central axis of the static frame clamping mechanism are disconnected from each other, and an induction heat treatment machine is arranged between them. The upsetting guiding shaft mechanism passing through the static frame clamping mechanism and the moving frame clamping mechanism is arranged below the induction heat treatment machine. The heat treatment normalizing coil of the induction heat treatment machine is located at the lower ends of the static frame clamping mechanism and the moving frame clamping mechanism and envelopes the circumference of the rail to be welded.

[0004] Judging from the drawings of the above-mentioned suspended rail flash welding and induction heat treatment integrated machine, operation consoles are respectively arranged on the top sides of the static frame clamping mechanism and the moving frame clamping mechanism. During operation, it is necessary to run back and forth between the two operation consoles, which is not convenient for operation. Summary of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the purpose of the present utility model is to provide an embedded control platform, a welding machine head thereof and a rail flash welding machine, so as to solve the problem in the prior art that the installation positions of the two operation consoles require the staff to run back and forth during operation, which is not convenient for operation.

[0006] To achieve the above object, the first aspect of the present utility model adopts the following technical solution: An embedded control platform, comprising two control consoles, both of which are installed on the outer shell of the same clamping mechanism and embedded therein, and the operation surfaces of the control consoles are directly connected to the outside of the outer shell.

[0007] The second aspect of the present utility model adopts the following technical solution: A welding machine head, comprising an embedded control platform as described in the first aspect of the present utility model.

[0008] The third aspect of the present utility model adopts the following technical solution: A rail flash welding machine, comprising a welding machine head as described in the second aspect of the present utility model.

[0009] Compared with the prior art, the present utility model has the following beneficial effects:

[0010] 1. In this embedded control platform, two control consoles are installed on the outer shell of the same clamping mechanism and embedded therein, and the operation surfaces of the control consoles are directly connected to the outside of the outer shell. Then, only one operator is required to stand on one side of the outer shell to directly operate the two control consoles, which is more convenient for operation and does not require the operator to run back and forth.

[0011] 2. Both control consoles are embedded in the outer shell, and the outer shell provides a certain degree of protection for the control consoles, making it difficult for the control consoles to be accidentally operated by people walking back and forth. Moreover, the outer shell is directly used as the installation support for the control consoles, eliminating the need for an additional support frame for installation, thus reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 is a schematic structural diagram of an embodiment of the present utility model Figure 1 ;

[0013] Figure 2 is a schematic structural diagram of an embodiment of the present utility model Figure 2 .

[0014] The reference numerals in the accompanying drawings of the specification include: control console 1, outer shell 2, mounting hole 3, signal integration module 4, clamping oil cylinder 5. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following further details the present utility model through specific embodiments:

[0016] Since the installation positions of the two control consoles 1 in the existing rail flash welding machine are relatively far apart, the operator needs to run back and forth between the two control consoles 1 during operation, which is not convenient for operation. To solve this problem, as Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides an embedded control platform, which includes two consoles 1. Both of the two consoles 1 are installed on the outer shell 2 of the same clamping mechanism and embedded in the outer shell 2, and the operating surfaces of the consoles 1 are directly connected to the outside of the outer shell 2.

[0017] In this embedded control platform, two consoles 1 are installed on the outer shell 2 of the same clamping mechanism and embedded in the outer shell 2, and the operating surfaces of the consoles 1 are directly connected to the outside of the outer shell 2. Then, only one staff member needs to stand on one side outside the outer shell 2 to directly operate the two consoles 1, which is more convenient and does not require the staff to run back and forth. The two consoles 1 are both embedded in the outer shell 2, and the outer shell 2 plays a certain protective role for the consoles 1, so that the consoles 1 are not easily misoperated by people walking back and forth. Moreover, the outer shell 2 is directly used as the installation support for the consoles 1, and there is no need to provide an additional support frame to install and support the consoles 1, thus reducing the cost.

[0018] To better understand this solution, the installation method of the console 1 and others will be further optimized below.

[0019] As Figure 2 shown, according to another embodiment of the present utility model, in the embedded control platform, the outer shell 2 includes a first outer shell section arranged in the vertical direction and a second outer shell section arranged obliquely. The lower end of the second outer shell section is connected to the upper end of the first outer shell section, and the two consoles 1 are arranged in a one-to-one correspondence on the first outer shell section and the second outer shell section.

[0020] The two consoles 1 are reasonably arranged at different positions on the outer shell 2 to avoid interference in the installation between the two consoles 1, which is beneficial for the staff to operate on the two consoles 1.

[0021] As Figure 2 shown, according to another embodiment of the present utility model, in the embedded control platform, each console 1 is provided with an installation hole 3 opened on the outer shell 2. The console 1 is arranged inside the outer shell 2, and the operation buttons on the console 1 all extend into the corresponding installation holes 3.

[0022] During installation: Place the console 1 inside the outer shell 2. Since the area of the console 1 is larger than the cross-sectional area of the installation hole 3, the console 1 cannot pass through the installation hole 3 to the outside of the outer shell 2, but the operation buttons on the console 1 are all inserted into the installation holes 3. Then, use screws, other existing locking structures or clamping structures, etc. to stably connect the console 1 inside the outer shell 2 for embedded installation of the console 1. The outer shell 2 plays a certain protective role for the console 1, and the staff can quickly operate the operation buttons on the console 1 by inserting their fingers into the installation holes 3, reducing the misoperation of the console 1.

[0023] As Figure 2As shown, according to another embodiment of the present utility model, the embedded control platform further includes a signal integration module 4 connected to both control consoles 1. The signal integration module 4 is disposed within the housing and is connected to the side of any one of the control consoles 1 facing the interior of the housing 2.

[0024] In this embodiment:

[0025] The signal integration module 4 is installed within the housing for protection and is directly connected to any one of the control consoles 1 for reasonable layout, facilitating the disassembly and assembly of the signal integration module 4 together with the control console 1 during the disassembly and assembly of the control console 1, which is relatively convenient.

[0026] Among them, the signal integration module 4 is specifically connected to the engine, hydraulic system, cooling system, hanger system, rail alignment system, and welding system in the rail flash butt welder. Workers can operate on the two control consoles 1, and the signal integration module 4 is used for signal transmission and conversion, thereby controlling the start and stop of the engine, hydraulic system, cooling system, hanger system, rail alignment system, and welding system, etc. The operation is convenient; the engine, hydraulic system, cooling system, hanger system, rail alignment system, and welding system are all existing structures in the rail flash butt welder.

[0027] As Figure 2 shown, according to another embodiment of the present utility model, the welding machine head includes an embedded control platform as described in any one of the above embodiments, having the advantages of the embedded control platform and also being able to make the structure on the welding machine head more concise.

[0028] As Figure 2 shown, according to another embodiment of the present utility model, the welding machine head further includes a clamping oil cylinder 5. The clamping oil cylinder 5 is externally disposed on the top of the rail flash butt welder head. This reduces the space occupied by the clamping oil cylinder 5 within the rail flash butt welder head, is beneficial for having a larger maintenance activity space when the rail flash butt welder head fails, and is also beneficial for the maintenance of the clamping oil cylinder 5.

[0029] Among them, the clamping oil cylinder 5 is connected to the corresponding two static frame wedge clamps or two moving frame wedge clamps through transmission parts. The two static frame wedge clamps or two moving frame wedge clamps are rotatably connected to each other through a central shaft. The piston rod of the clamping oil cylinder 5 is connected to the central shaft. The transmission parts include a hinge seat connecting rod. One end of the hinge seat connecting rod is rotatably connected to the fixed oil cylinder housing of the clamping oil cylinder 5, and the other end is rotatably connected to the large arm ear on the corresponding static frame wedge clamp or the large arm ear on the moving frame wedge clamp.

[0030] When the piston rod of the clamping oil cylinder 5 moves downward, it drives the hinge seat connecting rod to swing inward, and the two static frame wedge-shaped clamps or the two moving frame wedge-shaped clamps rotate around the central axis, and the two static frame wedge-shaped clamps or the two moving frame wedge-shaped clamps open; when the piston rod of the clamping oil cylinder 5 moves upward, it drives the hinge seat connecting rod to swing outward, and the two static frame wedge-shaped clamps or the two moving frame wedge-shaped clamps rotate in the reverse direction around the central axis, and the two static frame wedge-shaped clamps or the two moving frame wedge-shaped clamps clamp.

[0031] The clamping oil cylinder 5 here corresponds to the first clamping cylinder block or the second clamping cylinder block in CN117961244A and the moving frame clamping oil cylinder 5 or the static frame clamping oil cylinder 5 in CN116551137A, and they are all installed inside the welding machine head. In comparison, the installation position of the clamping oil cylinder 5 in this solution is more convenient for its maintenance.

[0032] According to another embodiment of the present invention, the welding machine head further includes a moving frame wedge-shaped clamp and a static frame wedge-shaped clamp. A rail lifting mechanism is provided on the wedge-shaped clamping parts of the moving frame wedge-shaped clamp and the static frame wedge-shaped clamp. The rail lifting mechanism includes a lifting top block and a jacking assembly. Among them, at least part of the lifting top block is slidably arranged above the outer side of the wedge-shaped clamping part in the vertical direction and is used to abut against the inner top of the rail; the jacking assembly is arranged on the wedge-shaped clamping part and is connected to the lifting top block for driving the lifting top block to move between a preset first position and a second position.

[0033] During the process of clamping the rail by the wedge-shaped clamping part of this rail lifting mechanism, at the beginning, the lifting top block is placed at the preset first position, and then the jacking assembly is used to drive the lifting top block to move upward. The top of the lifting top block abuts against the inner top of the rail to lift the rail to the preset second position. The rail is accurately clamped by the wedge-shaped clamping part at the preset second position, reducing the adjustment time during the alignment of the rail; this rail lifting mechanism is installed in cooperation with the wedge-shaped clamping part, and during the process of clamping the rail, it can quickly and automatically align without additional auxiliary tools or manual touch for alignment, reducing safety problems; this rail lifting mechanism is installed in cooperation with the wedge-shaped clamping part, and during the process of clamping the rail, it reduces the inconvenience of operation and the large labor intensity, improving the production efficiency.

[0034] Among them, an installation through hole is opened in the wedge-shaped clamping part in the vertical direction, the jacking assembly is arranged in the installation through hole, and sealing structures are arranged at both ends of the installation through hole.

[0035] Here, the installation through hole provides an installation channel for the jacking assembly and also guides the movement of the jacking assembly, and the sealing structure seals the installation through hole.

[0036] Based on the above solution:

[0037] The jacking assembly includes a jacking rod and a positioning screw. The jacking rod is arranged in the installation through-hole. The positioning screw is connected between the jacking rod and the lifting top block. After injecting oil into the installation through-hole, the jacking rod forms an oil cylinder to provide driving force to drive the lifting top block to move between a preset first position and a second position. The positioning screw stably connects the jacking rod and the lifting top block.

[0038] Wherein, the sealing structure arranged at the bottom end of the installation through-hole can be an oil plug, and the sealing structure arranged at the top end of the installation through-hole can be an oil seal. One end of the jacking rod connected to the positioning screw freely passes through the central hole of the oil seal, so as to form a sealed space in the installation through-hole, and then hydraulic oil can be injected.

[0039] In order to make the lifting top block and the rail have a larger contact area when they are in contact, so as to lift the rail more stably; since the top of the inner side of the rail is an arc surface, the side surface of the lifting top block for contacting the rail is an arc surface, so that the lifting top block and the rail are in sealed contact.

[0040] It should be noted that when the shape of the top of the inner side of the rail changes, the side surface of the lifting top block for contacting the rail changes adaptively to ensure that the lifting top block and the rail have a large enough contact area when they are in contact, and the rail can be lifted more stably.

[0041] Wherein, a positioning step is formed on the top side of each wedge-shaped clamping part, and the bottom side of the lifting top block abuts against the positioning step. When the lifting top block is at the preset first position, the bottom side of the lifting top block abuts against the positioning step for stable arrangement. In this embodiment, the positioning step is in an "L" shape to ensure that the lifting top block has a large enough contact surface in the positioning step and improve the positioning stability of the lifting top block.

[0042] Based on the above scheme:

[0043] A rail top reference part is fixedly arranged above the position between the two cooperating wedge-shaped clamping parts. The rail top reference part is used to abut against the rail during rail lifting for positioning.

[0044] When the rail is lifted upward to abut against the rail top reference part, the lifting top block reaches the preset second position for accurate positioning at this position. At this time, the two wedge-shaped clamping parts move towards each other to accurately clamp the rail.

[0045] Furthermore, the welding machine head further includes an oil circuit integration block, and a clamping control valve cooperating with the clamping oil cylinder and a lifting control valve cooperating with the jacking assembly are arranged on the oil circuit integration block.

[0046] The specific operation during clamping is as follows:

[0047] When lifting the rail, the oil circuit integrated block is in the low-pressure oil supply state, the clamping control valve acts, the hydraulic oil flows into the clamping cylinder, the piston rod of the clamping cylinder moves upward, drives the hinge seat connecting rod to swing outward, the two wedge-shaped clamping parts move towards each other, and the two wedge-shaped clamping parts complete the initial positioning and clamping of the rail;

[0048] Then the rear lifting control valve acts, the hydraulic oil flows into the installation through hole through the oil circuit integrated block, the jacking rod runs, drives the lifting top block to move upward through the positioning screw until the rail contacts the rail top reference part, and the rail lifting is completed;

[0049] The oil circuit integrated block is switched to the high-pressure oil supply state, the piston rod in the clamping cylinder continues to move upward under high pressure, and the two wedge-shaped clamping parts continue to move towards each other until the rail is clamped;

[0050] The rear lifting control valve acts, the hydraulic oil flows into the installation through hole through the oil circuit integrated block to drive the jacking rod to move downward, and drives the lifting top block to move downward until it abuts against the positioning step, and the clamping is completed.

[0051] In this embodiment, for other structures in the welding machine head, reference can be made to the corresponding structures in CN117961244A or CN116551137A.
