Description

Technical Field

[0002] At present, the rail welding trolley is a device that can realize vertical welding, transverse welding, horizontal welding and other welding positions. It moves and positions on the track. The track is a mechanism installed on the corresponding workpiece for the welding trolley to move and position. The route, stability and position of the trolley are directly related to the track.

[0003] In the related art, welding of the circumferential seams of large cylinders is also often carried out using a welding trolley. The operation method is usually to install the track of the welding trolley on the outer periphery of the large cylinder, and the track is installed close to the circumferential seam to be welded. Since the length of a single track is limited, multiple tracks need to be spliced, and the spliced ​​tracks are arranged in a circle along the weld of the large cylinder.

[0004] When multiple tracks are enclosed in a ring, the length of the ring track is fixed. Due to the material of the large cylinder itself and other reasons, its weld usually needs to be preheated and post-heated before welding. The preheating and post-heating temperatures will reach 100 or even 200°C, and the welding trolley will also heat the large cylinder during the welding process. As the temperature rises, the large cylinder will expand and deform due to heat. However, since the length of the ring track is fixed, the expanded large cylinder will squeeze the ring track, causing the ring track to deform, or even squeeze and damage the ring track, which will affect the movement of the welding trolley, causing the welding trolley to deviate from the weld, affecting the welding quality. Summary of the invention

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] An embodiment of the present application provides a track for a welding trolley, which can solve the technical problem in the related technology that the expansion of a large cylinder will squeeze the circular track, causing the circular track to deform, or even squeeze and damage the circular track, thereby affecting the movement of the welding trolley, causing the welding trolley to deviate from the weld, and affecting the welding quality.

[0032] See also Figures 1 to 3 As shown, a track for a welding trolley provided in an embodiment of the present application may include: a cylinder track 1; a connecting piece 2, wherein the connecting piece 2 is provided with a long hole 21, and the connecting piece 2 is connected to the cylinder track 1 by a first bolt penetrated through the long hole 21, so that the cylinder track 1 and the connecting piece 2 together form an annular track 3, and the long hole 21 extends along the extension direction of the annular track 3, and the annular track 3 is used to be surrounded by the annular seam of a large cylinder 4, and the first bolt can be respectively penetrated through the cylinder track 1 and the connecting piece 2, at this time, the cylinder track 1 is relatively fixed with the first bolt, and the first bolt slides along the long hole 21, that is, the first bolt drives the cylinder track 1 to slide relative to the connecting piece 2, thereby changing the overall length of the connection between the cylinder track 1 and the connecting piece 2, that is, changing the circumference of the annular track 3.

[0033] In the embodiment of the present application, the cylinder track 1 is connected by a connecting piece 2, and a long hole 21 is opened in the connecting piece 2. When the first bolt is respectively penetrated through the long holes 21 of the cylinder track 1 and the connecting piece 2, the cylinder track 1 and the connecting piece 2 can form a circular track 3 together. Preferably, the cylinder track 1 can include multiple segmented splicing sections, and the splicing sections can be detachably connected to each other, so that the cylinder track 1 can adapt to large cylinders 4 of more sizes after being connected to the connecting piece 2. Since the circular track 3 is surrounded by the annular seam of the large cylinder 4, when the large cylinder 4 expands due to heat, the circular track 3 will also change with the expansion of the large cylinder 4. Since the long hole 21 is opened in the connecting piece 2, preferably, the long hole 21 can be a waist-round hole. The cylinder track 1 and the connecting piece 2 can increase the overall circumference of the annular track 3 by sliding the first bolt in the long hole 21, that is, at this time, the diameter of the annular track 3 changes with the expansion of the large cylinder 4, so that the annular track 3 is not easily damaged or deformed even if the circumference changes, and the extension direction of the connecting piece 2 in the waist hole can be regarded as the length direction. At this time, the length of the waist hole can be 2 cm and the width is 0.5 cm, so that the first bolt can only slide along the length direction after being passed through the waist hole, which solves the technical problem in the related technology that the annular track 3 will be squeezed by the expansion of the large cylinder 4, thereby causing the annular track 3 to deform and affect the welding quality of the welding carriage 5.

[0034] In some optional embodiments, the welding trolley track includes multiple sections of the barrel track 1, and two adjacent sections of the barrel track 1 are connected by the connecting piece 2, that is, the barrel track 1 can be set to one section or to multiple sections. When the barrel track 1 is set to one section, the connecting piece 2 connects the head and tail ends of one section of the barrel track 1. When the barrel track 1 is set to multiple sections, the connecting piece 2 connects two adjacent sections of the barrel track 1. In the embodiment of the present application, the barrel track 1 is provided with multiple sections; the connecting piece 2 is also provided with a fixing hole 22, and the fixing hole 22 and the long hole 21 are spaced apart along the extension direction of the connecting piece 2, and one of the two adjacent sections of the barrel track 1 is connected to the barrel track 1. The connecting piece 2 is fixed by a second bolt, and the second bolt is inserted into the fixing hole 22. The other section of the cylinder track 1 is connected to the connecting piece 2 by the first bolt inserted into the long hole 21. That is, at this time, one of the two adjacent sections of the cylinder track 1 is fixed to the connecting piece 2 through the fixing hole 22, and the connecting piece 2 and the section of the cylinder track 1 are relatively fixed, and the other section of the cylinder track 1 is slidably fixed with the connecting piece 2 through the long hole 21. This setting method can make the cylinder track 1 and the connecting piece 2 slide relative to each other. The connecting piece 2 only slides relative to the cylinder track 1 on one side, and the other side is relatively fixed, so that when the circumference of the annular track 3 changes, its overall shape is better controlled and not easy to deform. Preferably, the number of sections of the cylinder track 1 can be determined according to the material of the large cylinder 4 itself and other reasons. In actual work, when the staff finds that the large cylinder 4 itself expands greatly after heating, multiple sections of the cylinder track 1 can be set so that they can be connected with multiple sections of connecting pieces 2, so that the overall circumference of the annular track 3 can have a larger range of variation.

[0035] In some optional embodiments, see Figure 3As shown, the cylinder track 1 is provided with a plurality of first weight-reducing holes 11, and the first weight-reducing holes 11 are spaced apart from the first bolts and the second bolts, and the plurality of first weight-reducing holes 11 are arranged along the extension direction of the cylinder track 1. In actual work, in order to facilitate the movement of the welding trolley 5 on the annular track 3, the annular track 3 is usually made of steel or other materials with high rigidity. The plurality of first weight-reducing holes 11 are provided in the cylinder track 1, which can reduce the weight of the cylinder track 1 and reduce the rigidity of the cylinder track 1, making it easier to bend and surround the outer periphery of the large cylinder 4. In the embodiment of the present application, the first bolt and the second bolt are fixed on the cylinder rail 1. When the connecting plate 2 needs to be connected to the cylinder rail 1, it is only necessary to insert the first bolt and the second bolt into the fixing hole 22 and the long hole 21 respectively, and then tighten them with bolts. In some other embodiments, multiple holes for inserting the first bolt and the second bolt can be opened on the cylinder rail 1. At this time, the first weight-reducing hole 11 and the first bolt and the second bolt are spaced apart, so that the first weight-reducing hole 11 does not affect the connection between the cylinder rail 1 and the connecting plate 2.

[0036] Preferably, the connecting piece 2 is provided with a plurality of second weight-reducing holes 23, and the second weight-reducing holes 23 are arranged at intervals from the fixing holes 22 and the long holes 21, and the second weight-reducing holes 23 are arranged along the extension direction of the connecting piece 2, that is, at this time, a plurality of first weight-reducing holes 11 and second weight-reducing holes 23 are respectively provided in the connecting piece 2 and the cylinder rail 1, so that the connecting piece 2 can also be easily bent on the outer periphery of the large cylinder 4.

[0037] In some optional embodiments, see Figure 4 As shown, the connecting plate 2 is provided with a plurality of groups of the long holes 21, and the plurality of groups of the long holes 21 are arranged at intervals along the extension direction of the connecting plate 2, that is, a plurality of groups of the long holes 21 are arranged in the connecting plate 2 along the extension direction of the connecting plate 2 and connected with the first bolt, so as to enhance the stability of the connection between the connecting plate 2 and the cylinder rail 1.

[0038] Preferably, a plurality of fixing holes 22 are provided, a connecting line of the plurality of fixing holes 22 is perpendicular to the extension direction of the connecting piece 2, and the plurality of fixing holes 22 are symmetrically arranged on both sides of the second weight-reducing hole 23; a connecting line between the plurality of long holes 21 in each group of the long holes 21 is perpendicular to the extension direction of the connecting piece 2, and the plurality of long holes 21 in each group of the long holes 21 are symmetrically arranged on both sides of the second weight-reducing hole 23, and the extension direction of the connecting piece 2 can be regarded as the length direction. At this time, a plurality of fixing holes 22 and long holes 21 are provided in the width direction of the connecting piece 2, and the annular track 3 is It is more stably installed on the outer periphery of the large cylinder 4 and can be set to have a wider width so that the contact surface between the annular track 3 and the large cylinder 4 is larger. While multiple fixing holes 22 and long holes 21 are set on the connecting plate 2, the cylinder track 1 is also provided with first bolts and second bolts corresponding to the positions and numbers of the fixing holes 22 and the long holes 21, or holes through which the first bolts and the second bolts can be passed. Multiple fixing holes 22 and long holes 21 are set in the width direction of the connecting plate 2, which can make the connection between the annular track 3 and the large cylinder 4 more stable and strengthen the connection relationship between the cylinder track 1 and the connecting plate 2.

[0039] In some optional embodiments, the barrel track 1 is installed with a magnetic device, and the barrel track 1 can be fixed to the large barrel 4 by opening a plurality of bolt holes on the barrel track 1 so that the barrel track 1 is bolted to the large barrel 4. In the embodiment of the present application, the barrel track 1 is fixed to the large barrel 4 by magnetic attraction, and installing a magnetic device on the barrel track 1 can facilitate fixing the barrel track 1 to the large barrel 4 and removing the barrel track 1 from the large barrel 4.

[0040] Preferably, the magnetic device includes a plurality of switch magnets 12, and the plurality of switch magnets 12 are arranged at intervals along the extension direction of the cylinder track 1, that is, the switch magnets 12 can be used to facilitate the staff to control the force between the magnet and the large cylinder 4. When the cylinder track 1 needs to be removed from the large cylinder 4, the magnetism of the switch magnet 12 is turned off, and the cylinder track 1 is easier to be removed from the large cylinder 4. Preferably, the switch magnets 12 can be detachably mounted on the cylinder track 1, and the switch magnets 12 are arranged to be detachably mounted on the cylinder track 1 to facilitate the overall storage of the cylinder track 1. The cylinder track 1 is connected to the large cylinder 4 through a plurality of switch magnets 12. When the large cylinder 4 expands, the annular track 3 is also easier to change with the large cylinder 4. When the large cylinder 4 retracts during subsequent cooling, the cylinder track 1 is magnetically connected to the large cylinder 4, and the annular track 3 can also retract with the large cylinder 4. When retracting, the first bolt still slides in the long hole 21. Preferably, a switch magnet 12 may also be mounted on the connecting piece 2 .
