[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0039] Embodiment: This embodiment aims to provide a gantry crane track intersection area rapid track changing device, the main function of which is to realize single-person rapid track changing with high efficiency and low labor cost.

[0040] like Figure 1-4 As shown, the base 1 is arranged at the intersection center of the single and double tracks, and the front and rear edges of the base 1 are close to the ends of the corresponding longitudinal double tracks, and the left and right edges of the base 1 are close to the ends of the corresponding transverse single track. The surface of the base 1 is provided with through holes 4 for inserting anchor nails or bolts. The base 1 is fixed to the ground by passing the anchor nails or bolts through the through holes 4 to prevent the position of the base 1 from changing during use, effectively ensuring the stability of the device. A pair of longitudinal rail grooves 2 are provided and are located on the upper surface of the base 1. The length direction of the longitudinal rail grooves 2 is consistent with the extension direction of the double tracks, so that the longitudinal rail grooves The end of the track 2 is butted against the corresponding track end face; the transverse rail groove 3 is set individually and is also located on the upper surface of the base 1, and is staggered with the longitudinal rail groove 2. The length direction of the transverse rail groove 3 is consistent with the extension direction of the single track, so that the end of the transverse rail groove 3 is butted against the corresponding track end face, and the longitudinal rail groove 2 and the transverse rail groove 3 are both disconnected from it, so that the intersection of the longitudinal rail groove 2 and the transverse rail groove 3 is connected to each other, wherein the longitudinal rail groove 2 and the transverse rail groove 3 are both composed of a pair of groove plates welded in parallel on the base 1, and a triangular reinforcement plate 5 is welded between the outer side of the groove plate and the upper surface of the base 1.

[0041] like Figure 3-9As shown, the track changing frame includes: a movable rail 6 and a pad beam 7. The movable rail 6 is provided with a pair, and the two movable rails 6 are connected as a whole through the pad beam 7. The end of the pad beam 7 is at the intersection of the longitudinal rail groove 2 and the transverse rail groove 3. The height of the pad beam 7 is consistent with the height of the groove plate. The movable rail 6 only includes a track top plate and a half-section web plate, so that the two ends of the pad beam 7 are respectively rotatably connected to the middle of the bottom surface of the top plate of the two movable rails 6, thereby the two movable rails 6 have a steering function, so that the half-section web plate can be cyclically inserted into the longitudinal rail groove 2 and the transverse rail groove 3 by rotating the movable rail 6. Specifically, the movable rail 6 is divided into two sections. The front section only includes the track top plate and the track web plate, and does not include the track base, because the track web plate needs to be cyclically inserted between the longitudinal rail groove 2 and the transverse rail groove 3. The rear section only includes The track top plate, the lower plate surface of the track top plate of this section has a support 8 protruding downward, and the end of the pad beam 7 is rotatably mounted on the outside of the support 8. In order to meet the steering function of the movable rail 6, the track web of this section is removed to provide a rotation space for the movable rail 6, thereby avoiding interference with the pad beam 7 during the rotation of the movable rail 6. When the double track is passed, the two movable rails 6 are turned to be parallel. At this time, the track change frame is in an H shape as a whole, and then the track webs of the front sections of the two movable rails 6 are respectively inserted into the corresponding longitudinal rail groove 2. When the single track is passed, the two movable rails 6 are turned to be in the same straight line. At this time, the track change frame is in a straight line as a whole, and then the track webs of the front sections of the two movable rails 6 are respectively inserted into the corresponding transverse rail groove 3.

[0042] like Figure 4 and 7 As shown, the length of the longitudinal rail groove 2 is consistent with that of the movable rail 6, and the length of the two movable rails 6 is smaller than that of the transverse rail groove 3. When the movable rail 6 is in the transverse rail groove 3, the track change frame is in a straight line shape. An anti-interference gap is provided between the two movable rails 6 to prevent the two movable rails 6 from interfering with each other and failing to form a straight line when rotating. The gap between the two movable rails 6 is filled with a U-shaped patch 9 to ensure that the gantry crane can pass stably above the straight line-shaped track change frame.

[0043] In this embodiment, the height of the groove plate is consistent with the height of the track web of the movable rail 6. When the track web of the movable rail 6 is inserted into the corresponding longitudinal rail groove 2, the lower plate surface of the top plate of the rear section of the movable rail 6 just contacts the top of the groove plate constituting the groove, thereby ensuring that the top plate of the movable rail 6 is consistent with the height of the single and double tracks, and the lower end of the support 8 is flush with the bottom of the track web of the front section of the movable rail 6, so that the movable rail 6 in the transverse rail groove 3 is consistent with the height of the single and double tracks, thereby ensuring stable passage of the gantry crane in the track change area.

[0044] Reference Figure 4 、 Figure 5 and Figure 6By adjusting the direction of the movable rail 6 so that the length direction of the two movable rails 6 is consistent with the extension direction of the two longitudinal rail grooves 2, the track change frame as a whole is H-shaped, and the rail webs of the front sections of the two movable rails 6 are correspondingly inserted into the groove sections located on the front side of the base 1, and the rail top plates of the rear sections of the two movable rails 6 are correspondingly placed on the groove sections located on the rear side of the base 1, so that the rail top plates of the rear sections are supported by the groove plates of the rear side groove sections, and the overall length of the movable rail 6 is consistent with the length of the longitudinal rail groove 2.

[0045] Reference Figure 7 、 Figure 8 and Figure 9 The U-shaped patch block 9 is placed in the gap between the two movable rails 6 in the one-line shape, and the U-shaped mouth of the U-shaped patch block 9 is facing downward to buckle on the pad beam 7 in the gap between the two movable rails 6, thereby not affecting the stable and normal walking of the gantry crane rail wheel on the movable rail 6.

[0046] When track changing is required, only one person needs to lift the two movable rails 6 upwards through the cushion beam 7 to separate the rail webs from the corresponding groove sections, and then adjust the direction of the movable rails 6 corresponding to the longitudinal rail groove 2 or the transverse rail groove 3. After that, the cushion beam 7 is reset, and the rail webs of the two movable rails 6 are reinserted into the corresponding groove sections to complete the track changing, which improves the convenience and practicality of the track changing device, can effectively avoid labor waste, and save work costs.

[0047] The track changing device provided in this embodiment is simple and quick to operate, and can enable a single person to quickly complete the track changing operation, which is not only efficient but also does not increase labor costs.

[0048] It will be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
