Description

Technical Field

[0001] This utility model belongs to the technical field of gantry crane auxiliary equipment, specifically relating to a gantry crane traveling trolley rerailing device. Background Technology

[0002] To ensure efficient production operations at the wharf and facilitate the smooth berthing and unberthing of incoming vessels, the gantry crane requires frequent relocation and parking based on site conditions. After years of intensive use and weathering, the gantry crane's travel rails at the wharf have experienced varying degrees of settlement, resulting in inconsistent rail heights and significantly increasing the risk of derailment of the traveling trolley during crane relocations. In the past two years, there have been multiple incidents of trolley derailment during gantry crane relocations, which have not only impacted production operations but also created significant safety hazards.

[0003] Therefore, a gantry crane traveling trolley rerailing device is needed to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a gantry crane traveling trolley rerailing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gantry crane traveling trolley rerailing device includes guide rails, pins, and guide plates. Two guide rails are provided, which are detachably installed on the bottom of the guide plate and are symmetrically distributed. Both sides of the guide plate have slots with small pull plates inserted into them, which can be pulled out.

[0007] It should be noted in the solution that the bottom of the guide plate is fixed with a protrusion, and the guide rail is provided with a slot that fits the protrusion.

[0008] It is worth noting that the guide rail and the guide plate are provided with relatively aligned insertion holes, and the pins are properly fitted into the insertion holes.

[0009] It should be further noted that there are two of the aforementioned pins.

[0010] Preferably, the front of a single guide rail has multiple sockets.

[0011] Preferably, the guide plate has a groove on its side and the groove is located in the middle of the socket on the guide plate.

[0012] Compared with the prior art, the gantry crane traveling trolley rerailing device provided by this utility model has at least the following beneficial effects:

[0013] Two inclined guide rails are placed on either side of the travel track, with the leading edge of the guide rails pointing towards the derailment trolley. The front of the guide rails is then fixed to the top of the two guide rails using pins. The other two holes on the front of the guide rails are used to fine-tune the distance between the two guide rails (i.e., the width of the track). The small pull plates on the sides of the guide plate (one on each side) can be pulled out, and then a forklift can be used to lift it to a certain height to facilitate the installation of the guide rails on both sides. When the gantry crane's travel trolley encounters derailment, thanks to the stable support of the trolley column, it can effectively approach and fit tightly against the edge of the travel track. If the gantry crane travels towards the rerailer and reaches the leading edge of the inclined rail, as the travel trolley continues to advance along the ramp, under the combined force of the inclined rail and the trolley column, the travel wheels gradually rise and automatically converge towards the center axis of the track. This dynamic adjustment ensures that when the travel wheels reach the key intersection point of the long guide plate, they can align with and pass through the opening of the guide plate. The gantry crane continues to advance along the planned route. At this point, the left wheel flange (or right flange, depending on the actual orientation) is pressed against the left edge of the long guide plate, forming a stable guiding contact. Conversely, the right wheel flange (or left flange) maintains slight friction with the left edge of the short guide plate (right or left flange), working together to precisely control the gantry crane's re-railing path until it successfully reaches the front of the rear guide plate. Finally, under the smooth guidance of the rear guide plate, the traveling wheels safely and smoothly decrease in height via the sliding track, returning to the original traveling track. The entire re-railing process is smooth and efficient. The guide plate's two-centimeter depth is precisely the depth of the traveling wheels. This design ensures that the traveling wheels fit tightly when passing through the guide plate, with the main force concentrated on the wheel core. The edges of the traveling wheels play a guiding role, sliding precisely along the guide plate's contour to help the wheel core maintain the correct trajectory. This allows the gantry crane's own traveling function to restore the derailed trolley to its original position if it deviates from the track during travel. Attached Figure Description

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Please see Figure 1-2This utility model provides a gantry crane traveling trolley rerailing device, including guide rails 1, pins 2, and guide plates 3. Two guide rails 1 are provided, detachably installed at the bottom of the guide plate 3, and symmetrically distributed. Both sides of the guide plate 3 have slots with small pull plates 4 inserted into them, which can be pulled out. This gantry crane rerailing device is a detachable type, consisting of one guide plate 3, two guide rails 1 (left and right), two pins 2, and two small pull plates 4 (e.g., ...). Figure 1 Therefore, when installing the rerailing device, place two inclined guide rails 1 on both sides of the traveling track, with the leading edge of the guide rail pointing towards the derailment trolley. Then, fix the front of the guide rail 1 to the top of the two guide rails 1 using pins 2 (e.g., Figure 1 The small pull plates 4 (one on each side) on the side of the guide plate 3 can be pulled out, and then lifted to a certain height using a forklift to facilitate the installation of the guide rails on both sides. When the gantry crane's traveling trolley derails, thanks to the stable support of the trolley column, it can effectively approach and adhere to the edge of the traveling track. If the gantry crane travels towards the rerailer and reaches the inner inclined rail at the front edge, as the traveling trolley continues to advance along the slope, under the guidance of the inclination of the inclined rail and the combined force of the trolley column, the traveling wheels gradually rise and automatically converge towards the central axis of the track. This dynamic adjustment ensures that when the traveling wheels reach the key intersection point of the long guide plate, they can align with and pass through the opening of the guide plate 3. The gantry crane continues to advance along the planned route. At this time, the left wheel flange (or the right side, depending on the actual orientation) adheres tightly to the left edge of the long guide plate, forming a stable guiding contact; while the opposite right wheel flange (or left side) maintains slight friction with the left edge of the right (or left) short guide plate, working together to precisely control the rerailing path of the gantry crane until it successfully reaches the front of the rear guide plate. Finally, guided smoothly by the rear guide plate, the traveling wheelset safely and smoothly descends through the sliding track, returning to its original traveling track. The entire re-railing process is smooth and efficient. The guide plate's two-centimeter depth is precisely the depth of the traveling wheels. This design ensures that the traveling wheels fit tightly when passing through the guide plate, with the main force concentrated on the wheel core. The edges of the traveling wheels act as guides, sliding precisely along the contour of the guide plate 3, assisting the wheel core in maintaining the correct trajectory.

[0020] Further as Figure 2 As shown, it is worth noting that the bottom of the guide plate 3 is fixed with a protrusion 6, and the guide rail 1 is provided with a slot 7 that fits the protrusion 6. In actual operation, the guide rail 1 is conveniently installed on the bottom of the guide plate 3 by inserting the protrusion 6 into the slot 7.

[0021] Further as Figure 1 and Figure 2As shown, it is worth noting that the guide rail 1 and the guide plate 3 are both provided with relatively aligned insertion holes 5, and the pins 2 are properly inserted into the insertion holes 5. There are two pins 2. In use, the guide plate 3 and the guide rail 1 are connected by inserting the pins 2 into the insertion holes 5.

[0022] Further as Figure 1 As shown, it is worth noting that the front of a single guide rail 1 has multiple sockets 5; the other sockets 5 on the front of the guide rail 1 are used to fine-tune the distance between the two guide rails 1, that is, the width of the rail.

[0023] Further as Figure 1 As shown, it is worth noting that the guide plate 3 has a groove on its side and the groove is located in the middle of the socket on the guide plate 3; in actual operation, the small pull plate 4 can be easily removed through the groove, which is convenient for operation.

[0024] This solution involves the following steps: First, observe the track environment where the derailment trolley is located, and select a relatively flat location close to the derailment point. When installing the rerailing device, place two inclined guide rails 1 on both sides of the traveling track, with the leading edge of the guide rails pointing towards the derailment trolley. Then, fix the front of the guide rails 1 above the two guide rails 1 using pins 2. The small pull plates 4 (one on each side) on the side of the guide plate 3 can be pulled out, and then lifted to a certain height using a forklift to facilitate the installation of the guide rails on both sides. When the gantry crane's traveling trolley encounters derailment, thanks to the stable support of the trolley column, it can effectively approach and adhere to the edge of the traveling track. If the gantry crane moves towards the rerailing device and reaches the inner inclined rail at the leading edge, as the traveling trolley continues to advance along the slope, under the guidance of the combined force of the inclined rail and the trolley column, the traveling wheels gradually rise and automatically converge towards the center axis of the track. This dynamic adjustment ensures that when the traveling wheels reach the key intersection point of the long guide plate, they can align with and pass through the opening of the guide plate 3. The gantry crane continues along the planned route. At this point, the left wheel flange (or right flange, depending on the actual location) is in close contact with the left edge of the long guide plate, forming a stable guiding contact. Meanwhile, the opposite right wheel flange (or left flange) maintains slight friction with the left edge of the short guide plate on the right (or left) side. Working together, they precisely control the gantry crane's double-track path until it successfully reaches the front of the rear guide plate. Finally, guided smoothly by the rear guide plate, the traveling wheelset safely and smoothly lowers its height through the sliding track, returning to its original traveling track.
