Description

Technical Field

[0001] The utility model relates to the field of railway rail welding, in particular to a rain and snow proof and heat preservation tunnel for the roller path line of a rail welding base. Background Art

[0002] After the long railway rail is welded at the rail welding base, the welded joint needs to be heat-treated and then taken out of the warehouse. According to the heat treatment principle and Article 7.10.4 of the enterprise standard Q / CR 707-2019 "Fixed Rail Flash Welding" of China National Railway Group Co., Ltd.: After heat treatment, when the surface temperature of any part of the joint is higher than 200 °C, it should not be in contact with water or ice and snow.

[0003] At present, the main methods used in rail welding bases across the country are: one is to add houses, and the other is to start the secondary air injection emergency plan to ensure that the weld temperature does not come into contact with water or ice and snow when it is higher than 200 °C on rainy and snowy days. The first method has high costs and is restricted by the site. For example, in some rail welding bases, the heat treatment station is directly connected to the aging table, and houses cannot be added; the second method requires an extended operation time when using secondary air injection, which affects production efficiency. Both have certain drawbacks. Content of the Utility Model

[0004] In view of the above problems, the utility model discloses a rain and snow proof and heat preservation tunnel for the roller path line of a rail welding base, which can effectively ensure the normal operation of the roller path and extend the service life of the roller path.

[0005] The rain and snow proof and heat preservation tunnel for the roller path line of the utility model is erected on the roller path line and includes a fixed frame, a fixed side rain and snow proof baffle, and a movable side rain and snow proof baffle.

[0006] The fixed frame is arranged on the bracket of the roller path line along the length direction of the roller path line, the top surface is a horizontal plane, and both sides are supported on the ground by columns. Heating wires are laid on the bottom surface below the fixed frame.

[0007] The fixed frame includes a bottom plate and columns; among them, the bottom plate is a rectangular plate, the front and back length direction is along the roller path line direction, and an opening part is provided on the bottom plate corresponding to the position of the rollers on the roller path line; the bottom plate is laid on the bracket of the roller path line, and the opening part on the bottom plate avoids the rollers on the roller path line; at the same time, support positions are designed at equal intervals along the roller path line direction, and two columns are arranged at each support position, and the tops of the two columns are respectively fixed to the left and right sides of the bottom surface of the bottom plate by bolts.

[0008] The fixed side rain and snow proof baffle is perpendicular to the top surface of the fixed frame, and the bottom edge is fixedly connected to one long side of the fixed frame.

[0009] A positioning plate arranged obliquely is designed at the top edge of the fixed side rain and snow proof baffle, so that the included angle between the positioning plate and the bottom plate is n degrees; the positioning plate is located outside the roller path line in the transverse position of the roller path line and does not block the rails conveyed on the roller path line.

[0010] The movable side rain and snow shielding baffle has a movable side top plate and a movable side side plate; the movable side side plate is perpendicular to the top surface of the fixed frame, and the bottom edge is hinged to a support seat designed at the other long side of the fixed frame through a joint; and the hinge shaft is coaxially connected to the output shaft of the driving motor, and the driving motor is connected to the hinge shaft between the joint and the support seat located in the middle; one side edge of the top plate is fixedly connected to the top edge of the side plate, and the opposite side edge is connected to the top edge of the fixed side rain and snow shielding baffle.

[0011] Furthermore, the movable side top plate is a V-shaped structure composed of plane A and plane B, with the tip facing upward, and the included angles between both planes and the horizontal plane are both n degrees; wherein, a baffle extending outward is designed at the outer side edge of plane A of the movable side top plate to shield the gap formed by the connection between plane A and the side edge of the positioning plate; the outer side edge of plane B is connected and fixedly connected to the top edge of the movable side side plate; the outer side edge of plane A is connected to the other side edge of the positioning plate.

[0012] Furthermore, the joints at the bottom edge of the movable side side plate are designed at equal intervals along the roller path line and are respectively hinged to the support seats designed at equal intervals at the other long side of the fixed frame.

[0013] Furthermore, heat preservation layers are laid on the inner wall surfaces of the movable side rain and snow shielding baffle and the fixed side rain and snow shielding baffle.

[0014] Furthermore, induction lights are installed at equal intervals along the long direction on the outer walls of the movable side rain and snow shielding baffle and the fixed side rain and snow shielding baffle.

[0015] Thus, by controlling the driving motor, the movable side rain and snow shielding baffle can be driven to rotate and open around the hinge shaft. At this time, the steel rail on the roller path line is exposed, and hoisting operations can be carried out. On the contrary, by controlling the driving motor to reverse, the movable baffle is driven to rotate reversely around the hinge shaft. After it is connected to the top plate of the fixed side baffle, a tunnel that is closed in the overall circumference is formed, which can prevent the high-temperature steel rail weld from contacting rain and snow.

[0030] The anti-rain, snow and heat preservation tunnel for the roller table line in the rail welding base of the utility model is erected on the roller table line and shields both sides and the upper part of the roller table line. It includes a fixing frame 1, a fixed side anti-rain and snow baffle 2, a movable side anti-rain and snow baffle 3, a heat preservation layer 4, an induction lamp 5, a driving mechanism 6 and a heating wire, as Figure 1 , Figure 2 shown.

[0031] The fixing frame 1 includes a bottom plate 101 and support columns 102. Among them, the bottom plate 101 is a rectangular plate with a length of 7 m, and the long direction is set along the direction of the roller table line 7. And openings are provided on the bottom plate 101 corresponding to the positions of the rollers on the roller table line 7.

[0032] The bottom plate 101 of the above structure is laid on the support of the roller table line and is fixedly connected to the support of the roller table line through bolts; when laying, the bottom plate 101 avoids the rollers on the roller table line 7 through the designed openings on it, so that the rollers can pass through the openings and be located above the bottom plate 101. At the same time, support positions are designed at equal intervals along the direction of the roller table line 7, and two support columns 102 are arranged at each support position. The tops of the two support columns 102 are respectively fixed to the left and right sides of the bottom surface of the bottom plate 101 through bolts, and the bottoms are arranged on the ground. Thus, the bottom plate 101 is supported by the track line 8 and the support columns 102 together.

[0033] The fixed-side rain and snow baffle 2 includes a fixed-side side plate 201 and a positioning plate 202. The fixed-side side plate 201 is a rectangular plate with the same length as the bottom plate 101, is perpendicular to the bottom plate 101, is installed on one side of the bottom plate 101, and its lower long side is connected and welded to the side edge of the bottom plate 101. Its height should be greater than the height of the rail top conveyed by the roller path line 7. The positioning plate 202 is located at the top of the fixed-side side plate 201 and is set at an angle of n degrees with the bottom plate, where n is 30 to 45 degrees, and is used for docking and positioning with the movable-side rain and snow baffle 3. The length of the positioning plate 202 is equal to the length of the fixed-side side plate 201. One long side is the connecting side and is connected to the top edge of the fixed-side side plate 201, and the opposite long side is the positioning side for cooperating with the positioning side in the movable-side rain and snow baffle 2. The position of this positioning side in the transverse direction of the roller path line is outside the roller path line and does not block the rails conveyed on the roller path line. Heat preservation layers 4 are laid on the inner wall surfaces of the above-mentioned fixed-side side plate 201 and positioning plate 202.

[0034] The movable-side rain and snow baffle 3 includes a movable-side side plate 301 and a movable-side top plate 302. Among them, the size of the movable-side side plate 301 is the same as that of the fixed-side side plate 201, and they are symmetrically arranged left and right with respect to the fixed-side side plate 201. The movable-side top plate 302 is a V-shaped plate with two side surfaces and serves as the top main body of the entire rain and snow heat preservation tunnel. The included angle between the two side surfaces is 120°. One long side of one side surface of the movable-side top plate 302 is the connecting side and is connected and welded to the top edge of the movable-side side plate 301, and the included angle between this side surface and the bottom plate 101 is n degrees. The long side of the other side surface of the movable-side top plate 302 is the positioning side for cooperating with the positioning side of the positioning plate 202. Heat preservation layers 4 are laid on the inner wall surfaces of both the movable-side side plate 301 and the movable-side top plate 302. Combining with the heat preservation layer 4 laid on the inner wall of the fixed-side rain and snow baffle 2, it can prevent the temperature of the rail weld from dropping too fast due to the too low outdoor temperature in winter, resulting in changes in the internal structure and affecting the welding quality.

[0035] A plurality of joints 303 are designed at equal intervals along the length direction on the outer wall of the above-mentioned movable-side side plate 301, and rotating shafts with axes arranged along the length direction of the roller path line 7 are designed on each joint 303. At the same time, connecting beams 103 corresponding to the positions of each joint 303 are designed at equal intervals along the length direction at the same-side side edge of the bottom plate 101.

[0036] A connecting seat 104 is designed on the top surface of each of the above-mentioned connecting beams 103 and is respectively hinged to the rotating shafts on each joint 303 to form a rotating pair. Thus, the driving mechanism 6 can control the opening and closing movement of the movable-side rain and snow baffle 3.

[0037] The driving mechanism 6 is a driving motor. The driving motor is fixedly arranged in a motor housing installed on the side of the middle connecting beam 103, and the output shaft is coaxially connected to the outermost rotating shaft through a coupling. Thus, through the driving mechanism 6, the entire movable-side rain and snow baffle 3 can be driven to rotate around the rotating shafts connected to its joints 303.

[0038] In the present utility model, a heating wire is also laid on the bottom surface below the bottom plate 101, which can help melt snow. At the same time, induction lamps 5 are installed at equal intervals along the length direction on the outer walls of the movable side rain and snow baffle 3 and the fixed side rain and snow baffle 2, which play a role of lighting and warning during the hoisting of the rail.

[0039] For the anti-rain and snow heat preservation tunnel of the rail welding base roller path line of the present utility model, when the rail hoisting operation is not carried out, the movable side rain and snow baffle 3 is in a normally closed state. As Figure 2 shown, in this state, the outer side edge of the top plate 302 of the movable side rain and snow baffle 3 is in contact with the positioning plate 202 of the fixed side rain and snow baffle 2, and the two together form the top of the entire tunnel; further, a baffle 304 extending outward can be designed on the top surface of the movable side top plate 302 and at the outer side edge to block the gap formed between the two, so that rain and snow will not enter the tunnel interior through the gap. In the above normally closed state, it plays a role in preventing the high-temperature rail weld from contacting rain and snow. In this state, the induction lamp is in an extinguished state.

[0040] When the operation of opening the movable side rain and snow baffle 3 is carried out, the driving motor controls the rotation of the rotating shaft to make the entire movable side rain and snow baffle 3 rotate outward around the rotating shaft to the outside of the roller path line until the movable side rain and snow baffle 3 rotates to a position where there is no obstruction above the rail on the roller path line, and then the driving motor stops working. At this time, it is in a fully open state, as Figure 3 shown. When the rail hoisting operation is carried out, the movable side rain and snow baffle 3 is in an open state, and the induction lamp 5 lights up; after the rail hoisting is completed, the driving motor controls the rotating shaft to rotate in the reverse direction, and the movable side rain and snow baffle 3 returns to the normally closed state.

[0041] The anti-rain and snow heat preservation tunnel of the rail welding base roller path line of the present utility model is simple in operation, convenient in installation, and strong in practicability. It can effectively avoid the rapid cooling of the high-temperature weld after leaving the warehouse when encountering rain, snow or low-temperature bad weather, or contacting the water-containing roller, and generating harmful tissues such as martensite.
