Description

Technical Field

[0001] The utility model relates to the technical field of rail welding auxiliary equipment, in particular to a welding fire prevention device. Background Art

[0002] The domestic railway industry is rapidly developing. With increasing freight volume, the cycle between major and medium-sized repairs and rail replacements is shrinking, while routine maintenance and rail replacements are becoming more frequent, resulting in an increasingly demanding task of rail welding. Among these, pneumatic rail welding, a newly emerging automated rail welding method, has gained widespread recognition and adoption across domestic railway units due to its integrated preheating, welding, and normalizing operation. During the pneumatic rail welding process, a fireproof plate is inserted into the welding torch's heating stroke to prevent damage to the welder during the heating of the rails.

[0003] In the prior art, since the original fireproof board requires the operator's hands to reach within the range of the torch heating when installing and removing it, if an error occurs during the operation, causing the torch heating part to move mechanically, it is very easy to cause injury to the operator. Utility Model Content

[0004] The utility model provides a welding fire prevention device, which is used to enable an operator to operate the welding fire prevention device by operating a gripping rod.

[0005] The utility model provides a welding fire prevention device, comprising:

[0006] First fireproof board;

[0007] two second fireproof panels, the two second fireproof panels being movably disposed on both sides of the first fireproof panel; and

[0008] Two holding rods, the two holding rods being connected to the two second fireproof boards respectively;

[0009] The holding rod is configured to drive the second fireproof board to switch between the first position and the second position, and the two second fireproof boards can cooperate with the first fireproof board to clamp on the surface of the rail when they are in the first position.

[0010] In some embodiments, the two second fire prevention panels are rotatably disposed on both sides of the first fire prevention panel.

[0011] In some embodiments, the first fire prevention board and the second fire prevention board are staggered in the thickness direction.

[0012] In some embodiments, the two second fire prevention panels are rotatably connected to the first fire prevention panel via rivets.

[0013] In some embodiments, the first fire protection board has a first clamping surface, and the second fire protection board has a connected second clamping surface and a third clamping surface. When the two second fire protection boards are in the first position and cooperate with the first fire protection board to clamp the rail, the first clamping surface abuts the upper surface of the rail, the second clamping surface abuts the side surface of the rail, and the third clamping surface abuts the lower surface of the rail.

[0014] In some embodiments, the two second fire prevention boards are both provided with a limiting surface, and the two limiting surfaces are configured to limit the two second fire prevention boards to be in the first position when they abut against each other.

[0015] In some embodiments, the holding rod includes a first connecting rod and a second connecting rod, the two ends of the first connecting rod are respectively connected to the second connecting rod and the second fireproof plate, and the extension direction of the first connecting rod is perpendicular to the extension direction of the second connecting rod.

[0016] In some embodiments, the first connecting rod is configured such that, when the second fire protection plate is in the first position, the extension direction of the first connecting rod is parallel to the vertical direction, and the end faces of the two second connecting rods away from the first connecting rod are in opposite directions.

[0017] In some embodiments, the first connecting rod is configured such that, when the second fire protection panel is in the first position, the extension direction of the first connecting rod is parallel to the horizontal direction, and the end faces of the two second connecting rods away from the first connecting rod are oriented in the same direction.

[0018] In some embodiments, the first fire protection board is provided with a handle.

[0019] This application provides a welding fire prevention device, which has at least the following beneficial effects compared with the prior art:

[0020] The embodiment of the present application provides a gripping rod connected to the second fireproof plate, so that the operator can adjust the position of the second fireproof plate by holding the gripping rod. Since the position of the operator's gripping rod is far away from the second fireproof plate, compared with the prior art that requires the operator to extend his hand into the range of the torch heating to install and remove the fireproof plate, it can ensure that the operator can operate the welding fireproof device outside the heating range, thereby ensuring the safety of the operator. At the same time, by providing the first fireproof plate and two second fireproof plates, a relatively closed fireproof area can be formed during the welding process, effectively blocking the splashing of high-temperature substances such as sparks and slag, thereby protecting the welding machine of the pneumatic rail welding vehicle.

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] In this application, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0033] In addition, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may or may not be the same in type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0034] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.

[0035] Please also refer to Figure 1 and Figure 2 The embodiment of the present application provides a welding fire prevention device 1, comprising a first fire prevention plate 11, two second fire prevention plates 12, and two gripping rods 13. The two second fire prevention plates 12 are movably disposed on either side of the first fire prevention plate 11, and the two gripping rods 13 are connected to the two second fire prevention plates 12. The gripping rods 13 are configured to drive the second fire prevention plates 12 to switch between a first position and a second position, and when the two second fire prevention plates 12 are in the first position, they can cooperate with the first fire prevention plate 11 to clamp onto the surface of the rail.

[0036] When the welding fire protection device 1 is in use, the two second fire protection boards 12 are roughly located on the left and right sides of the first fire protection board 11 , and the first fire protection board 11 is roughly located above the two second fire protection boards 12 .

[0037] In the embodiment of the present application, when the welding fire protection device 1 is in a non-working state, the two second fire protection plates 12 are both in the first position.

[0038] When the welding fire protection device 1 is needed to clamp the steel rail to be processed, the operator first drives the two second fire protection plates 12 from the first position to the second position by holding the two holding rods 13, so that the first fire protection plate 11 forms a clamping space between the two second fire protection plates 12, and then places the welding fire protection device 1 above the steel rail and slowly moves downward to allow the steel rail to gradually enter the clamping space until the lower surface of the first fire protection plate 11 abuts against the upper surface of the steel rail.

[0039] The operator then holds two holding rods 13 to drive the two second fireproof panels 12 from the second position to the first position, so that the first fireproof panel 11 cooperates with the two second fireproof panels 12 to be clamped on the surface of the rail, thereby achieving a fire prevention effect.

[0040] The embodiment of the present application provides a gripping rod 13 connected to the second fireproof plate 12, so that the operator can adjust the position of the second fireproof plate 12 by holding the gripping rod 13. Since the position of the operator's gripping rod 13 is far away from the second fireproof plate 12, compared with the prior art that requires the operator to extend his hand into the range of the torch heating stroke to install and remove the fireproof plate, it can ensure that the operator can operate the welding fireproof device 1 outside the heating formation range, thereby ensuring the safety of the operator. At the same time, by providing the first fireproof plate 11 and the two second fireproof plates 12, a relatively closed fireproof area can be formed during the welding process, effectively blocking the splashing of high-temperature substances such as sparks and slag, thereby protecting the welding machine of the pneumatic welding rail car.

[0041] In some embodiments, the two second fire prevention boards 12 are rotatably disposed on both sides of the first fire prevention board 11 .

[0042] The second fireproof board 12 is rotatably connected to the first fireproof board 11. When the operator holds the gripping rod 13, the operator applies a force to the gripping rod 13 to form a torque, thereby driving the second fireproof board 12 to rotate. It is understood that the farther the operator holds the gripping rod 13 from the second fireproof board 12, the less force the operator can use to drive the second fireproof board 12 to rotate, thereby reducing the difficulty of the operator driving the second fireproof board 12 and ensuring that the operator is further away from the second fireproof board 12, further ensuring the operator's safety.

[0043] In some other embodiments, the two second fire protection panels 12 can be slidably disposed on the first fire protection panel 11 .

[0044] In some embodiments, the first fire prevention board 11 and the second fire prevention board 12 are staggered in the thickness direction.

[0045] Among them, the first fireproof board 11 and the second fireproof board 12 are staggered in the thickness direction, which means that the first fireproof board 11 and the second fireproof board 12 at least partially overlap in the thickness direction, which can avoid interference between the second fireproof board 12 and the first fireproof board 11 during rotation.

[0046] In some other embodiments, the first fire prevention board 11 and the second fire prevention board 12 may not be misaligned in the thickness direction, that is, the first fire prevention board 11 and the second fire prevention board 12 may at least partially overlap in the height direction.

[0047] In some embodiments, the two second fire prevention panels 12 are rotatably connected to the first fire prevention panel 11 via rivets 14 .

[0048] The second fireproof plate 12 is rotatably connected to the first fireproof plate 11 by rivets 14, which reduces the complexity of the connection structure between the second fireproof plate 12 and the first fireproof plate 11 and reduces the manufacturing cost of the second fireproof plate 12 and the first fireproof plate 11.

[0049] In some other embodiments, the second fire protection board 12 and the first fire protection board 11 may also be connected by components such as hinges.

[0050] In some embodiments, the first fire protection board 11 has a first clamping surface 111, and the second fire protection board 12 has a connected second clamping surface 121 and a third clamping surface 122. When the two second fire protection boards 12 are in the first position and cooperate with the first fire protection board 11 to clamp the rail, the first clamping surface 111 abuts the upper surface of the rail, the second clamping surface 121 abuts the side of the rail, and the third clamping surface 122 abuts the lower surface of the rail.

[0051] In this embodiment, when the two second fire panels 12 are in the first position and cooperate with the first fire panel 11 to clamp the rail, the first clamping surface 111 fits the upper surface of the rail, the second clamping surface 121 of one second fire panel 12 fits the side of one side of the rail, and the second clamping surface 121 of the other second fire panel 12 fits the side of the other side of the rail, and the third clamping surfaces 122 of the two second fire panels 12 both fit the lower surface of the rail. It should be noted that the sum of the areas of the third clamping surfaces 122 of the two second fire panels 12 can be roughly equal to the lower surface of the rail.

[0052] In some other embodiments, the first clamping surface 111 of the first fireproof plate 11 can abut against the upper surface of the rail and a portion of the side surface connected to the upper surface.

[0053] In some embodiments, both second fire prevention panels 12 are provided with a limiting surface 123 , and the two limiting surfaces 123 are configured to limit the two second fire prevention panels 12 to be in the first position when they abut against each other.

[0054] During the process of the two second fire protection panels 12 being converted from the second position to the first position, the limiting surfaces 123 of the two second fire protection panels 12 gradually approach each other. When the limiting surfaces 123 of the two second fire protection panels 12 abut against each other, the two second fire protection panels 12 are restricted from continuing to move and are confined to the first position.

[0055] By the mutual abutment of the limiting surfaces 123 of the two second fire prevention panels 12, the accurate positioning of the two second fire prevention panels 12 at the first position can be ensured, and the limiting method is simple and reliable.

[0056] In some other embodiments, a limiter may be provided on the first fire protection board 11, and when the limiter abuts against the second fire protection board 12 during the process of the second fire protection board 12 switching from the second position to the first position, the second fire protection board 12 stops at the first position.

[0057] In some embodiments, the holding rod 13 includes a first connecting rod 131 and a second connecting rod 132, the two ends of the first connecting rod 131 are respectively connected to the second connecting rod 132 and the second fireproof board 12, and the extension direction of the first connecting rod 131 is perpendicular to the extension direction of the second connecting rod 132.

[0058] The extension direction of the second connecting rod 132 is perpendicular to the extension direction of the first connecting rod 131, which can limit the length of the first connecting rod and prevent the first connecting rod 131 from being too long, which makes it inconvenient for the operator to directly hold the first connecting rod for operation.

[0059] In some other embodiments, the angle between the extending direction of the first connecting rod 131 and the extending direction of the second connecting rod 132 may be smaller than 90°.

[0060] In some embodiments, the first connecting rod 131 is configured so that when the second fire protection board 12 is in the first position, the extension direction of the first connecting rod 131 is parallel to the vertical direction, and the end faces of the two second connecting rods 132 away from the first connecting rod 131 are in opposite directions.

[0061] When the second fire protection panels 12 are in the first position, the extension direction of the first connecting rod 131 is parallel to the vertical direction and faces upward, and the ends of the two second connecting rods 132 away from the first connecting rod 131 are horizontally separated from each other. When the two second fire protection panels 12 are in the first position and it is necessary to switch the two second fire protection panels 12 from the first position to the second position, the operator holds the second connecting rod 132 and applies a generally upward force to the two second connecting rods 132, thereby driving the two second fire protection panels 12 to switch from the first position to the second position.

[0062] In other embodiments, the first connecting rod 131 is configured so that when the second fire protection board 12 is in the first position, the extension direction of the first connecting rod 131 is parallel to the horizontal direction, and the end faces of the two second connecting rods 132 away from the first connecting rod 131 are oriented in the same direction.

[0063] When the second fire protection panels 12 are in the first position, the extension direction of the first connecting rod 131 is parallel to the horizontal direction, and the end surfaces of the two first connecting rods 131 away from the second fire protection panels 12 face opposite directions, while the end surfaces of the two second connecting rods 132 away from the first connecting rod 131 face the same direction. When the two second fire protection panels 12 are in the first position and it is necessary to switch the two second fire protection panels 12 from the first position to the second position, the operator holds the second connecting rod 132 and applies a substantially horizontal force in opposite directions to the two second connecting rods 132, thereby driving the two second fire protection panels 12 to switch from the first position to the second position.

[0064] In some embodiments, the first fire protection board 11 is provided with a handle 15 .

[0065] The first fireproof plate 11 is provided with a handle 15 to facilitate operators to carry the welding fireproof device 1 .

[0066] In some other embodiments, the operator may also hold the gripping rod 13 to carry the welding fire protection device 1 .

[0067] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
