For closed ground torch, when the torch is operated, the personnel in the windproof wall is forbidden to enter, and the operating personnel can only check the operation states of the pilot lamp and the burner outside the windproof wall through the observation hole on the windproof wall, but can not enter the inner side of the windproof wall to maintain the pilot lamp. The contents of a pilot lamp that typically require maintenance include: 1) adjustment or replacement of ignition electrodes, 2) adjustment of air doors of ejectors, and 3) replacement of ignition high-voltage cables.

Aiming at the defect that a pilot lamp of a ground torch in the prior art cannot be maintained on line during the operation of the torch, the utility model provides a pilot lamp assembly. As shown in fig. 1 to 7, the pilot lamp assembly according to the present utility model includes a burner 100, a mixing gas pipe 110, an ejector 120, a guide pipe 130, a sliding member 140, and a push-pull member. A first end of the mixing gas pipe 110 is connected to the burner tip 100. The eductor 120 is connected to the second end of the mixing gas tube 110. The first end of the guide tube 130 is connected to the burner tip 100. The guide tube 130 is used to accommodate an ignition device. The length direction of the guide tube 130 is consistent with the length direction of the gas mixture tube 110. One end of the sliding member 140 may be connected to one or both of the mixing gas pipe 110 and the guide pipe 130. The other end of the sliding member 140 is adapted to be connected to a guide rail 190 in the wind-proof wall 170 of the enclosed floor torch and is slidably guided to be fitted to the guide rail 190 along the extending direction of the guide rail 190. The sliding guide fit is understood here to be similar to the fit between a linear guide and a slider. One end of the push-pull member is detachably connected to at least one of the mixing gas pipe 110, the ejector 120, and the guide pipe 130. The other end of the push-pull member is adapted to extend outside the wind-resistant wall 170 for applying a force to the slide member 140 in the extending direction of the guide rail 190 in operation.

The pilot lamp assembly can be constructed into a high-temperature resistant stainless steel structure, and meets the use requirement of a torch in a high-temperature environment. The tolerance temperature of the pilot lamp assembly can be not lower than 600 ℃ so as to meet the use requirement of the ground torch in a high-temperature environment, and the reliability and the service life of the pilot lamp assembly are greatly improved. When the anti-wind lamp assembly is used, the guide rail 190 is arranged in the anti-wind wall 170, and an operator can push or pull down the anti-wind wall 170 along the extending direction of the guide rail 190, so that the anti-wind lamp assembly can move into the anti-wind wall 170 or move out of the anti-wind wall 170, and further the anti-wind lamp assembly can be maintained.

The pilot lamp assembly may be understood to include a pilot lamp body and a mounting accessory. The pilot lamp body may include a burner 100, a gas mixing pipe 110, a guide pipe 130, and an injector 120. The mounting accessory may include a push-pull member.

According to the pilot lamp assembly of the present utility model, by detachably coupling the push-pull member to at least one of the mixing gas pipe 110, the injector 120 and the guide pipe 130, in the case that the slide member 140 is coupled to the guide rail 190, by operating the push-pull member to move along the guide rail 190, the structures of the injector 120, the mixing gas pipe 110, the guide pipe 130 and the burner 100 can be protruded outside the wind-proof wall 170, so that the pilot lamp assembly can be maintained on-line, and safety is greatly improved since there is no need to enter the wind-proof wall 170.

By adopting the pilot lamp assembly and matching the guide rail 190 in the wind-proof wall 170, even if an operator does not need to enter a high-temperature and high-risk area in the wind-proof wall 170 during the operation of the enclosed ground torch, the pilot lamp assembly can be integrally moved along the extending direction of the guide rail 190 and pass through the mounting hole 171 reserved on the wind-proof wall 170, so that the pilot lamp assembly is partially or completely extracted out of the wind-proof wall 170, and the corresponding part of the pilot lamp assembly can be maintained. After the maintenance operation of the pilot lamp assembly is completed, the pilot lamp assembly is also installed to the guide rail 190 and moved in the extending direction of the guide rail 190 by operating outside the wind-proof wall 170. Therefore, by adopting the scheme, the assembly, the disassembly, the assembly and the maintenance of the pilot lamp assembly are very convenient during the operation of the torch system; the safe and reliable operation of the pilot lamp assembly is ensured, and the reliability of the whole operation of the closed ground torch is greatly improved.

Referring to fig. 1, 4, 5 and 7, the pilot lamp assembly further includes an ignition extension rod 150. The ignition extension rod 150 may be provided with at least one. The ignition extension rod 150 is detachably connected to the second end of the guide tube 130. The ignition extension rod 150 connected to the guide tube 130 is used to connect an ignition device, i.e., one of the at least one ignition extension rod 150 is used to directly connect to the guide tube 130, and the ignition extension rod 150 directly connected to the guide tube 130 mounts the ignition device. Each of the at least one ignition extension rod 150 is connected in turn to each of the ignition extension rods 150. At least one of the ignition extension bars 150 constitutes a push-pull member, in other words, a combination of all of the ignition extension bars 150 in the at least one ignition extension bar 150 constitutes a push-pull member that can be held by an operator to apply a force to enable movement of the pilot lamp body.

With continued reference to fig. 1, 4, 5 and 7, in the illustrated embodiment, two ignition extension rods 150 are provided, and the two ignition extension rods 150 are connected in sequence along the rod length direction of the ignition extension rod 150. An ignition device is mounted on one of the ignition extension rods 150. After the ignition extension bar 150 and the ignition device are assembled, the assembly of the ignition extension bar 150 and the ignition device is assembled to the guide tube 130 together, and the ignition device is assembled into the guide tube 130, and the guide tube 130 positions and guides the ignition device. Wherein, after the ignition device is mounted on the ignition extension rod 150, one end of the ignition device, which is far away from the ignition extension rod 150, is provided with an ignition electrode; after the ignition device is fitted into the guide tube 130, the ignition electrode of the ignition device is brought close to the burner 100 so as to ignite the mixed gas outputted from the burner 100.

Referring to fig. 1-3, 5 and 7, for example, the ejector 120 has a mixing chamber 122 inside. The mixing chamber 122 is used for mixing the fuel gas and the air. The ejector 120 is provided with an air inlet 121a, an air inlet 121b and an air outlet 121c communicating with the mixing air chamber 122. The air inlet 121a and the air outlet 121c are located at both ends of the ejector 120 in the longitudinal direction, respectively. The length direction of the ejector 120 is parallel to the length direction of the mixing gas pipe 110. The gas outlet 121c is connected to a second end of the gas mixture pipe 110 for outputting a mixed gas of air and fuel gas to the gas mixture pipe 110, and the mixed gas is supplied to the burner 100 via a guide of the gas mixture pipe 110. The air intake 121b is located at a side of the ejector 120. The air inlet 121b is provided with an air door movable in the longitudinal direction of the ejector 120. The moving damper is used for adjusting the covered area of the air inlet 121b, that is, by moving the damper along the length direction of the ejector 120, the cross-sectional area of the air inlet 121b for air circulation can be adjusted, so that the air inlet speed is adjusted, and the flame size can be adjusted.

With continued reference to fig. 1-3, 5 and 7, the pilot lamp assembly further includes an air inlet tube 160. The intake pipe 160 is provided with at least one. The intake pipe 160 is detachably connected to the intake port 121a. And, each air inlet pipe 160 is located at one side of the ejector 120 away from the mixed air pipe 110 along the length direction of the ejector 120, and is sequentially arranged along the length direction of the ejector 120. For example, two air intake pipes 160 are provided, one of the two air intake pipes 160 is directly detachably connected to the air intake port 121a, and two adjacent air intake pipes 160 are detachably connected. At least one of the air inlet pipes 160 constitutes a push-pull member, i.e., a combination in which all of the air inlet pipes 160 of the at least one air inlet pipe 160 are connected in sequence may be used as the push-pull member. After each of the intake pipes 160 is connected in sequence and with the intake port 121a of the ejector 120, the intake pipe 160 furthest from the ejector 120 is used to connect the fuel gas pipe. In the illustrated embodiment, two air intake pipes 160 are provided.

With continued reference to fig. 1-3, 5 and 7, to facilitate adjustment of the position of the damper, the damper may have an operating portion 125 for adjustment. The pilot lamp assembly may also include an adjustment lever 126. The adjustment lever 126 is provided with at least one. The adjustment lever 126 is detachably connected to the operation portion 125. At least one of the adjustment bars 126 is disposed in sequence along the bar length direction of the adjustment bar 126, i.e., at least one of the adjustment bars 126 is connected in sequence along the bar length direction of the adjustment bar 126.

Referring to fig. 2, the operation portion 125 of the damper may be a rod structure. The length direction of the rod structure may be identical to the length direction of the ejector 120.

Referring to fig. 2 and 3, for another example, the ejector 120 may include a housing 121. The outer contour of the housing 121 is cylindrical. The interior of the housing 121 forms a mixing chamber 122. The outer surface of the housing 121 is provided with an air inlet 121a, an air inlet 121b and an air outlet 121c. The damper may be configured as a sleeve 124. The sleeve 124 is movably sleeved outside the housing 121 in the axial direction of the housing 121. The axial direction of the housing 121 is parallel to the axial direction of the sleeve 124. In the present utility model, the sleeve 124 may be slidably coupled to the housing 121 in the axial direction of the housing 121. The air intake amount of the air inlet 121b can be adjusted by pushing and pulling the adjusting lever 126. The housing 121 may be configured as a venturi tube, using a venturi effect, so that air is automatically introduced from the air intake port 121 b.

In other embodiments of the utility model, sleeve 124 may also be threadably coupled to housing 121. When the sleeve 124 rotates relative to the housing 121, the sleeve 124 moves in the axial direction of the housing 121, thereby adjusting the intake air quantity of the intake vent 121 b. Because the sleeve 124 is connected with the shell 121 in a threaded connection manner, the axial position of the sleeve 124 along the shell 121 can be limited when the position of the sleeve 124 is not required to be adjusted, and the position of the sleeve 124 can be adjusted by rotating the sleeve 124 when the position of the sleeve 124 is required to be adjusted, so that the adjustment of the position of the sleeve 124 is simpler and more reliable.

Further, in the embodiment in which the sleeve 124 and the housing 121 are screwed, the adjusting rods 126 connected in series in sequence may also constitute the push-pull member described above. For example, two adjusting rods 126 are provided, one of the two adjusting rods 126 is used to directly connect to the operating portion 125, and the two adjusting rods 126 are sequentially connected in the rod length direction of the adjusting rod 126. After the two adjustment levers 126 are connected to the operation unit 125, the adjustment levers 126 can be used as push-pull members. The adjusting lever 126 farthest from the operation part 125 can conveniently move the pilot lamp body from the high temperature region inside the wind-proof wall 170 to the non-high temperature region outside the wind-proof wall 170, and can move the pilot lamp body from the high temperature region outside the wind-proof wall 170 to the high temperature region inside the wind-proof wall 170.

With continued reference to fig. 2 and 3, further, the air inlets 121b may be disposed at intervals along the circumferential direction of the housing 121, so that air may simultaneously enter the mixing chamber 122 from the circumferential side of the housing 121, thereby improving air inlet efficiency and simultaneously facilitating sufficient mixing of air and fuel gas.

Referring to fig. 1, 5 and 7, in the illustrated embodiment, a sliding member 140 may be connected to a middle portion of the mixing tube 110. Compared with the sliding member 140 arranged at one end of the mixing gas pipe 110, which is closer to the burner 100, the sliding member 140 is arranged in the middle of the mixing gas pipe 110, so that after the pilot lamp body moves in place on the guide rail 190, the burner 100 is prevented from being too close to the guide rail 190, and the flame of the burner 100 is prevented from being influenced by the guide rail 190; at the same time, it also helps to reduce the length dimension of the guide rail 190. It is more advantageous to maintain the balance of the weight of the pilot lamp body on both sides of the sliding member 140 than to dispose the sliding member 140 at an end of the mixing gas pipe 110 closer to the ejector 120. If the sliding member 140 is disposed at the end of the gas mixing tube 110 closer to the injector 120, and the center of gravity of the pilot lamp body may be closer to the burner 100, then when the pilot lamp body is mounted on the guide rail 190, an operator needs to hold the end of the pilot lamp body away from the center of gravity for assembly operation, which is relatively laborious, so that the operation is not so flexible and convenient.

Referring to FIG. 3, the eductor 120 may further include a gas nozzle 123. The gas nozzle 123 is disposed inside the mixing chamber 122. An inlet of the gas nozzle 123 is connected to the gas inlet 121a. The outlet of the gas nozzle 123 is directed toward the gas outlet 121c. The provision of the gas nozzle 123 allows the fuel gas to more reliably enter the gas mixture pipe 110, thereby helping to prevent the fuel gas from leaking from the air intake port 121 b. For example, the outlet of the gas nozzle 123 may be closer to the burner 100 than the inlet 121 b.

Referring to fig. 5 and 7, in the festive lantern assembly of the present utility model, the connection between the adjusting lever 126 and the operating part 125 and the connection between the adjacent adjusting levers 126 may be screw connection. The connection between the air inlet pipe 160 and the ejector 120 and the connection between the adjacent air inlet pipes 160 may use a screw connection or a flange connection. The connection between the ignition extension rod 150 and the guide tube 130 and the connection between the adjacent ignition extension rods 150 may be screw connection.

Referring to fig. 1-7, the present utility model also provides a closed floor torch that may include a windbreak wall 170, a torch barrel 180, a burner (not shown), a guide rail 190, and a pilot lamp assembly according to the above. The wind-proof wall 170 is provided with a mounting hole 171 at a side thereof. The mounting holes 171 are respectively connected to the inside and outside of the wind-proof wall 170. The flare barrel 180 is located inside the windbreak wall 170. The flare barrel 180 may be arranged concentric with the wind wall 170 with a burner disposed in the middle of the circular area enclosed by the flare barrel 180. The guide rail 190 is disposed to the inside of the windbreak wall 170 and below the flare barrel 180. One end of the guide rail 190 is disposed corresponding to the mounting hole 171 and may be connected to the wind-proof wall 170. The other end of the rail 190 may be connected to the lower portion of the flare barrel 180. The slide member 140 of the pilot lamp assembly is movably connected to the guide rail 190 in the extending direction of the guide rail 190. When the pilot lamp assembly is connected to the guide rail 190, the burner 100 of the pilot lamp assembly is closer to the burner so as to timely ignite the combustible off-gas discharged from the burner when the burner 100 is in a normal combustion state. The movement of the pilot lamp assembly from the mounting hole 171 in the extending direction of the guide rail 190 may be allowed when the pilot lamp assembly is moved in the extending direction of the guide rail 190 by the slide member 140.

According to the enclosed floor torch of the present utility model, by providing the guide rail 190 between the torch barrel 180 inside the wind-proof wall 170 and the inner wall of the wind-proof wall 170 and connecting the pilot lamp assembly to the guide rail 190 through the sliding member 140, the pilot lamp body is moved in and out from the mounting hole 171 of the wind-proof wall 170 by operating the push-pull member of the pilot lamp assembly, thereby facilitating the maintenance operation of the pilot lamp assembly.

Referring to fig. 5-7, for example, the rail 190 may include a first rail section 191. The first rail section 191 is inclined to the height direction of the wind-proof wall 170. The first rail section 191 has first and second ends spaced apart along the extending direction of the rail 190. The first end of the first rail section 191 is higher than the second end of the first rail section 191, and the second end of the first rail section 191 is closer to the mounting hole 171 than the first end of the first rail section 191. When an operator operates at the mounting hole 171 outside the wind-proof wall 170, the pilot lamp body can be moved from the first end of the first guide rail section 191 to the second end of the first guide rail section 191 by pulling any one of the ignition extension bar 150, the adjustment bar 126, and the air inlet pipe 160 of the pilot lamp assembly, so that part or all of the pilot lamp body is moved outside the wind-proof wall 170. Similarly, by pushing any one of the ignition extension bar 150, the adjustment bar 126, and the air inlet pipe 160 of the pilot lamp assembly, the pilot lamp body can be moved from the second end of the first guide rail section 191 to the first end of the first guide rail section 191 until the slide member 140 is moved to the first end of the pilot lamp body.

With continued reference to fig. 5-7, further, the rail 190 can further include a second rail segment 192. A first end of the second rail segment 192 is connected to a first end of the first rail segment 191. The second end of the second rail segment 192 is further from the first rail segment 191 than the first end of the second rail segment 192, and the second end of the second rail segment 192 is not higher than the first end of the second rail segment 192. By providing the second guide rail segment 192, the end of the second guide rail segment 192 away from the first guide rail segment 191 is not higher than the first end of the second guide rail segment 192, so that after the sliding member 140 moves from the first guide rail segment 191 to the second guide rail segment 192, the sliding member 140 is ensured to reliably stay in the second guide rail segment 192, and the whole of the festive lantern assembly cannot slide downwards along the extending direction of the first guide rail segment 191 due to the dead weight of the festive lantern assembly. That is, the second rail segment 192 helps the pilot lamp assembly to be reliably and stably supported, thereby enabling the pilot lamp assembly to reside in the second rail segment 192.

Referring to fig. 7, for example, the second rail segment 192 may be perpendicular to the height of the windbreak wall 170. That is, the direction of extension of the second rail segment 192 may be in a horizontal direction to facilitate positioning the burner 100 of the pilot lamp assembly located at the second rail segment 192 at a height that enables accurate alignment of the burner 100 with the burner when the second rail segment 192 resides.

Referring to fig. 5-7, in order to prevent sliding member 140 from sliding off the end of second rail segment 192 during movement of sliding member 140 from first rail segment 191 to second rail segment 192, rail 190 may further include a stop member 193. The stop member 193 is disposed at a second end of the second guide rail segment 192, i.e., the stop member 193 is located at an end of the second guide rail segment 192 remote from the first guide rail segment 191. Also, the stopper member 193 is provided corresponding to the slide member 140 connected to the guide rail 190. The stop member 193 serves to limit the disengagement of the slide member 140 from the second end of the second rail segment 192.

With continued reference to fig. 5-7, in the illustrated embodiment, the stop member 193 is configured as a stop pin. The sliding member 140 located at the second rail section 192 continues to move away from the first rail section 191 by abutment and blocking of the stop pin.

Referring to FIG. 6, by way of example, the flare barrel 180 may be connected to an upper portion of the first rail section 191. And the distance of the flare barrel 180 from the first end of the first guide rail section 191 is greater than the distance of the flare barrel 180 from the second end of the first guide rail section 191.

Referring to fig. 1 and 4, in the illustrated embodiment, the sliding member 140 includes a hanger bar 142 and a hook 141. One end of the boom 142 is connected to the mixing gas pipe 110. The other end of the boom 142 is connected to a hanger 141 for hooking to the rail 190. The specific configuration of the hooks 141 is set according to the configuration of the guide rail 190.

Referring to fig. 5 to 7, for example, the guide rail 190 is constructed of H-shaped steel having first plate bodies parallel to each other and a second plate body connected between the two first plate bodies. When the H-section steel is made into the guide rail 190, one end of the H-section steel with a certain length is bent, the bending axis is perpendicular to the second plate body and parallel to the first plate body, and an included angle formed at the bending position is an obtuse angle. The included angle formed at the bending position, namely the included angle between the first guide rail section 191 and the second guide rail section 192. The angle at which the guide rail 190 is bent is arranged downward when the guide rail is installed. Accordingly, the hanger 141 may be configured as a U-shaped portion 141a and a hooking portion 141b formed to extend from both end portions of the U-shaped portion 141a toward each other. The two hanging parts 141b are arranged at intervals, and the intervals of the two hanging parts 141b are used for accommodating the second plate body. The two hanging parts 141b are used for being lapped on the upper surface of the lower one of the two first plate bodies. The U-shaped portion 141a is provided in the opening space for accommodating the lower one of the two first plates. Briefly, the illustrated hanger 141 provides a T-shaped receiving opening through which an inverted T-shaped structure on the rail 190 can be moved. The T-shaped structure is formed by a second plate body and the lower one of the two first plate bodies. As will be appreciated by those skilled in the art, as a variant of the guide rail 190, the guide rail 190 may also be constructed as a steel structure having a T-shaped cross section.

With continued reference to fig. 5-7, rail 190 may be made of i-steel, such as high temperature stainless steel, or other materials. One end of the I-steel is welded and fixed with the barrel body of the torch barrel 180, and the other end is fixed with the inner wall of the windproof wall 170. After the I-steel is installed in place, one end is high and the other end is low. A small flat area is formed at the higher end of the i-beam by bending to eliminate the sliding force along the rail 190 after the pilot lamp assembly is in place. The higher end of the rail 190 is provided with a stop pin to prevent the pilot lamp assembly from falling off the end of the rail 190 when installed.

Referring to fig. 1-7, a rail mounted pilot lamp assembly may be made of a high temperature stainless steel material. The burner 100 may be a burner 100 with a shield as shown, which is advantageous for stabilizing the flame and preventing the flame from extinguishing due to the wind. The air inlet 121a of the ejector 120 may be connected to a fuel pipe outside the windbreak wall 170 through a plurality of air inlet pipes 160. The operating portion 125 of the sleeve 124 may be coupled to a plurality of adjustment bars 126 extending beyond the wall 170 so that the damper may be adjusted outside the wall 170. The guide tube 130 may be welded to one or both of the gas mixture tube 110 and the windshield of the burner 100. The ignition device may be serially connected to the ignition extension rod 150 prior to insertion of the ignition device within the guide tube 130. The ignition device may be implemented using the structure of CN 216667746U. The end of one end of the guide tube 130 is adjacent to the burner 100 and the end of the other end may be connected in series with the ignition extension bar 150 until the end of the ignition extension bar 150 furthest from the guide tube 130 can extend beyond the windbreak wall 170. The ignition extension bar 150 extending outside the windbreak wall 170 is connected to an ignition cable located outside the windbreak wall 170. The sliding member 140 is welded to the mixing pipe 110 and may be hung on the guide rail 190. When the pilot lamp assembly is hung on the guide rail 190 through the sliding member 140, the pilot lamp assembly can conveniently move along the guide rail 190, which is beneficial to quick disassembly and assembly of the pilot lamp assembly. The size of the mounting holes 171 in the windbreak wall 170 may be adapted to the outer dimensions of the pilot lamp assembly so that the pilot lamp assembly may pass through.

Referring to fig. 5 and 7, the enclosed floor torch may further include an ignition cable (not shown) and a fuel gas pipe (not shown). The ignition cable is connected to an ignition extension rod 150 remote from the guide tube 130. One end of the fuel gas pipe is detachably connected to the intake pipe 160 remote from the ejector 120. The other end of the fuel gas pipe is used for being connected to a gas source. The ignition cable and the fuel gas pipe may be constructed in a structure commonly used in the art.

Referring to fig. 7, the adjusting lever 126, the ignition extension lever 150, and the intake pipe 160 are provided in two, respectively. The disassembly process of the pilot lamp assembly is as follows: in the (a) state, the pilot lamp assembly is in a mounted position on the rail 190, at which time the ignition cable may be removed from the ignition extension pole 150. In the state of (b), the outermost regulating rod 126, the air inlet pipe 160 and the ignition extension rod 150 of the pilot lamp assembly are completely removed out of the wind-proof wall 170, and the outermost regulating rod 126, the air inlet pipe 160 and the ignition extension rod 150 are removed. In the state (c), the pilot lamp is continuously pulled outward along the extending direction of the guide rail 190, so that the rest of the adjusting rod 126, the air inlet pipe 160 and the ignition extension rod 150 are completely moved out of the wind-proof wall 170, and the rest of the adjusting rod 126, the air inlet pipe 160 and the ignition extension rod 150 are removed. In the state (d), the pilot lamp body can be continuously pulled outwards, so that the pilot lamp body is positioned at a maintainable position, and the pilot lamp body can be completely pulled out of the windproof wall 170 when necessary.

With continued reference to fig. 7, the pilot lamp assembly is accessible to an operator outside of the windbreak wall 170 when disassembly for maintenance is required. The first step is to disconnect the pilot lamp assembly from the fuel gas pipe outside the windbreak wall 170, to pull out the pilot lamp assembly, to remove the first ignition extension rod 150, the first adjusting rod 126 and the first air inlet pipe 160, and to pull out the rest of the pilot lamp assembly along the guide rail 190 until the second ignition extension rod 150, the adjusting rod 126 and the air inlet pipe 160 are completely outside the windbreak wall 170. In the second step, the second adjusting rod 126, the ignition extension rod 150 and the air inlet pipe 160 are removed, and then the rest of the pilot lamp assembly can be integrally and externally pulled out again along the guide rail 190 until the part to be maintained is located outside the wind-proof wall 170, so that the pilot lamp body can be safely maintained.

Referring again to fig. 7, after maintenance of the pilot lamp body is completed, the disassembly steps described above may be reversed to install the pilot lamp (12) in place.
