Description

Technical Field

[0001] The utility model belongs to the technical field related to rail production, in particular to a rail mounting device for rail welding. Background Art

[0002] Nowadays, with the rapid development of high-speed railways, the demand for long rails is increasing, and higher requirements are placed on the efficiency of rail welding plants. Most of the super-long rails used in high-speed railways and urban rail seamless lines are welded and constructed through rail welding bases. Therefore, it is necessary to load short rails into welding equipment through rail loading devices for welding. However, it still has the following disadvantages in actual use:

[0003] The upper rail of the rail is directly operated by the crane. During the operation of the crane, the movement range is large, and the rail can only be roughly placed on the welding equipment, which is easy to cause the rail to be skewed. It is necessary to perform secondary alignment on the welding equipment. However, a certain length of rail is prone to skew. After the secondary clamping, the inclination is still large, causing the weld to be skewed, affecting the welding accuracy of the rail, and it is not convenient to align when putting the rail on;

[0004] When the rails are being put on the track, they are grabbed by a crane. During the grabbing process, the crane can only perform two actions: lowering and grabbing. The rails require additional conveying equipment to transport the ends to the welding position of the welding equipment. During the transportation process of the additional conveying equipment, a limiting structure is required to prevent the rails from deviating. The process of putting the rails on the track is relatively complicated. Utility Model Content

[0005] The utility model aims to provide a rail-mounting device for rail welding, which solves the problems of inconvenience in aligning the rails to the welding position when the rails are directly grabbed by a crane and a relatively complicated process for preventing deviation when conveying the rails, by arranging supporting channel steel, double-headed electric push rods, connecting strips and fixing plates.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a rail-mounting device for rail welding, comprising a supporting channel steel, a double-headed electric push rod, a connecting strip and a fixing plate, wherein connecting blocks are fixed at the two short sides of the tops of the two supporting channel steels, and a double-headed electric push rod is fixed on one side of the tops of the two supporting channel steels close to each other, the double-headed electric push rod is arranged between the two supporting channel steels, a connecting strip is arranged above each of the supporting channel steels, and a fixing plate is arranged above the two connecting strips. When working, a structure that drives and restricts the movement of the rails is connected thereto through the supporting channel steel, and the two connecting blocks are driven to approach and move away from each other through the double-headed electric push rod, so that the two supporting channel steels clamp the rails or are ready to clamp the rails, the lifting electric push rod is connected to the bottom of the lifting electric push rod through the connecting strip, and the connecting strip is hung on an external supporting device through the fixing plate.

[0008] Furthermore, a fixing bar is fixed on the side away from each other in the support channel steel, and a plurality of inner rotating rollers are rotatably connected on the sides of the two fixing bars close to each other. The circumferential sides of adjacent inner rotating rollers are movably connected with a transmission belt, and the support channel steel rotatably connects the inner rotating rollers therein through the fixing bar.

[0009] Furthermore, an external motor is fixed on one side of the two fixed bars away from each other, a driving shaft is fixed on the output end of the external motor, the driving shaft is inserted through the fixed bar, and the end of the driving shaft away from the external motor is fixed to an inner rotating roller. The inner rotating roller is driven to rotate by the driving shaft driven by the external motor, and then all the inner rotating rollers in the same supporting channel steel rotate together under the drive of the transmission belt.

[0010] Furthermore, a rotating shaft is fixed to one end of all the inner rotating rollers away from the fixed bar, and the rotating shaft is inserted into the side of the supporting channel steel away from the fixed bar. A roller is fixed to one end of all the rotating shafts away from the supporting channel steel, and the inner rotating rollers are connected to the rollers via the rotating shafts, and the rails are supported thereon via the rollers.

[0011] Furthermore, lifting electric push rods are fixed at the two short sides at the bottom of the connecting strip, the telescopic ends of the lifting electric push rods are facing downward, and the telescopic ends of the lifting electric push rods at the bottom of the same connecting strip are respectively fixed to the tops of the two connecting blocks at the top of the same supporting channel steel, and a T-shaped slider is fixed in the middle of the tops of the two connecting strips. The connecting strip drives the connecting blocks to rise and fall through the lifting electric push rods, thereby driving the supporting channel steel to rise and fall.

[0012] Furthermore, the fixed plate is provided with mounting holes in a rectangular array vertically therethrough, a sliding plate is fixed to the bottom of the fixed plate along the transverse center line, T-shaped slots are symmetrically provided at the bottom of the sliding plate, and the two T-shaped sliders are respectively slidably connected in the two T-shaped slots to determine the movement range of the two supporting channel steels when working.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that it is not convenient to align the rail with the welding position when the rail is directly grabbed by a crane by the crane. When the two connecting blocks driven by the same double-headed electric push rod are close to each other, the two supporting channel steels are driven to be close to each other. When the supporting channel steels are close to each other, the rollers connected by the rotating shaft of the two supporting channel steels are driven to enter the groove of the rail until the double-headed electric push rod drives the two connecting blocks to abut against the two ends of the double-headed electric push rod, the T-shaped sliding block just abuts against the T-shaped groove, the roller enters the groove of the rail, pushes and restricts the position of the rail, so that the center of the end of the rail and the welding position are on the same vertical plane, and the welding position can be aligned only by lifting, so that the rail can be directly restricted to the appropriate welding position when the rail is on the rail, and it is more convenient to align the rail with the welding position.

[0015] The utility model solves the problem of a relatively complicated process of preventing the rails from running off when conveying them by arranging supporting channel steel, double-headed electric push rods, connecting strips and fixing plates. During the rising process of the supporting channel steel, the rails are driven to rise. When the rails rise to the welding position aligned with the rail welding equipment, the external motor is started to drive the driving shaft to rotate, which drives the inner rotating roller to rotate. When the inner rotating roller rotates, the rotating shaft is driven to rotate. The rotating shaft rotates, which drives the rollers to rotate. When the rollers rotate, the rails between the rollers are driven to move to the welding equipment, and the ends are moved to the welding position to prepare for welding. This simplifies the process of preventing the rails from running off when conveying them. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiments

[0026] See also Figure 1-6 The utility model is a rail-mounted device for rail welding, comprising a supporting channel steel 1, a double-headed electric push rod 2, a connecting strip 3 and a fixed plate 4. Connecting blocks 201 are fixed at the two short sides of the tops of the two supporting channel steels 1. The supporting channel steel 1 rotatably connects the inner rotating roller 102 therein. A double-headed electric push rod 2 is fixed on one side of the tops of the two supporting channel steels 1 that are close to each other. The double-headed electric push rod 2 is arranged between the two supporting channel steels 1. The connecting blocks 201 are driven to approach and move away from each other by the double-headed electric push rod 2, so as to drive the rollers 107 to approach each other. A connecting strip 3 is arranged above each supporting channel steel 1, and the T-shaped slider 301 on the connecting strip 3 is slidably connected to the sliding plate 402 at the bottom of the fixed plate 4, so that the supporting channel steel 1 is hung at the bottom of the fixed plate 4. A fixing plate 4 is arranged above the two connecting strips 3. The fixing plate 4 is installed together with external equipment to provide support for the supporting channel steel 1, the double-headed electric push rod 2 and the connecting strip 3.

[0027] Specifically, a fixing bar 101 is fixed on the side away from each other in the support channel steel 1, and a plurality of inner rotating rollers 102 are rotatably connected on the sides of the two fixing bars 101 that are close to each other. The peripheral sides of adjacent inner rotating rollers 102 are movably connected with a transmission belt 103. The support channel steel 1 connects the inner rotating rollers 102 inside the support channel steel 1 through the fixing bar 101, and transmits the power of the external motor 104 to each inner rotating roller 102 through the transmission belt 103.

[0028] Furthermore, an external motor 104 is fixed to one side of the two fixed bars 101 away from each other, and a driving shaft 105 is fixed to the output end of the external motor 104. The driving shaft 105 is inserted through the fixed bar 101, and one end of the driving shaft 105 away from the external motor 104 is fixed to an inner roller 102. The external motor 104 controls the driving shaft 105 to rotate, thereby driving the inner roller 102 to rotate. When the inner roller 102 rotates, the rotating shaft 106 is driven to rotate.

[0029] Furthermore, a rotating shaft 106 is fixed to one end of all the inner rotating rollers 102 away from the fixed bar 101. The rotating shaft 106 is inserted into the side of the supporting channel steel 1 away from the fixed bar 101. A roller 107 is fixed to one end of all the rotating shafts 106 away from the supporting channel steel 1. When the rotating shaft 106 is driven to rotate by the inner rotating roller 102, the roller 107 is driven to rotate. When the roller 107 rotates, the conveyor rail moves to the welding equipment.

[0030] The operation process of this embodiment is as follows: during operation, when the supporting channel steel 1 drops to the point where the roller 107 is flush with the depression of the rail on the ground, the double-headed electric push rod 2 is started, and the double-headed electric push rod 2 drives the two connecting blocks 201 to approach each other. When the two connecting blocks 201 driven by the same double-headed electric push rod 2 approach each other, the two supporting channel steels 1 are driven to approach each other. When the supporting channel steels 1 approach each other, the roller 107 connected by the rotating shaft 106 is driven to enter the groove of the rail, until the double-headed electric push rod 2 drives the two connecting blocks 201 to abut against the two ends of the double-headed electric push rod 2, the T-shaped slider 301 just abuts against the T-shaped groove 403, and the roller 107 enters the groove of the rail, pushing and restricting the position of the rail so that the center of the rail end and the welding position are on the same vertical plane, and the welding position can be aligned by simply lifting. Specific embodiments

[0031] See also Figure 1 , 4 , 5, 6, on the basis of the specific embodiment 1, the two short sides at the bottom of the connecting bar 3 are fixed with lifting electric push rods 302, the telescopic ends of the lifting electric push rods 302 are facing downward, and the telescopic ends of the lifting electric push rods 302 at the bottom of the same connecting bar 3 are respectively fixed to the tops of the two connecting blocks 201 at the top of the same supporting channel steel 1, and a T-shaped slider 301 is fixed in the middle of the tops of the two connecting bars 3. The connecting bar 3 drives the connecting block 201 to rise and fall through the lifting electric push rods 302, thereby driving the supporting channel steel 1 to rise and fall.

[0032] Specifically, the fixed plate 4 is provided with mounting holes 401 in a rectangular array and vertically penetrate therethrough. A sliding plate 402 is fixed to the bottom of the fixed plate 4 along the horizontal center line. T-slots 403 are symmetrically provided at the bottom of the sliding plate 402. Two T-slot sliders 301 are respectively slidably connected in the two T-slots 403. The fixed plate 4 is movably connected to mounting bolts through the mounting holes 401. The mounting bolts are inserted into the mounting holes 401 on the fixed plate 4 and then screwed into the external supporting device. When working, the fixed plate 4 is installed on the external supporting device and slidably connected to the T-slot 403 on the sliding plate 402 through the T-slot slider 301. When working, the connecting bar 3 is hung under the fixed plate 4.

[0033] The operation process of this embodiment is as follows: when working, first insert the mounting bolts into the mounting holes 401 on the fixing plate 4, and then screw them into the external supporting device (the center of the external supporting device is aligned with the welding position of the rail to ensure that the rail is directly transported to the welding position after being put on the rail). When working, the fixing plate 4 is installed on the external supporting device, and the rail is pre-placed between the rollers 107 on the rotating shaft 106 connected by the driving shaft 105 between the two supporting channel steels 1, and then the two lifting electric push rods 302 at the bottom of the connecting bar 3 are started to drive the connecting block 201 to drive the supporting channel steel 1 to descend, and the double-headed electric push rods After the driving roller 107 enters the groove of the rail and limits the position, the lifting electric push rod 302 is started to drive the support channel steel 1 to rise. During the rising process of the support channel steel 1, the rail is driven to rise. When the rail rises to the welding position aligned with the rail welding equipment, the external motor 104 is started to drive the driving shaft 105 to rotate, driving the inner rotating roller 102 to rotate. When the inner rotating roller 102 rotates, the rotating shaft 106 is driven to rotate. Through the rotation of the rotating shaft 106, the roller 107 is driven to rotate. When the roller 107 rotates, the rail between the rollers 107 is driven to move to the welding equipment, and the end moves to the welding position to prepare for welding.
