Description

Technical Field

[0001] This application belongs to the technical field of power supply cables for gantry cranes, specifically an auxiliary walking system suitable for low-voltage large machinery in ports. Background Technology

[0002] With the development of the port industry, the use of large loading and unloading equipment is becoming increasingly widespread, and the normal power supply of gantry crane cables has become an important guarantee for the efficient operation of the terminal. At present, the low-voltage gantry crane head cables in the industry are usually fixed with chains, which often result in kinking and wear of the head cables during movement; or fixed steering devices are used to fix the head cables, which makes it impossible to efficiently replace the gantry crane junction box when the gantry crane moves a long distance.

[0003] Some docks have already attempted to develop new cable turning devices, but problems such as low disassembly and assembly efficiency and inflexible turning have resulted in less than ideal results.

[0004] For example, Chinese patent CN220182592U discloses a power supply cable reversing device for a gantry crane, including a fixed base. The fixed base includes a base plate, a base, a pressure plate seat, and a pressure cover. The surface of the base plate is provided with multiple bolt mounting holes. The base is fixedly connected to the base plate. The pressure plate seat is bolted to the base. The pressure plate seat and the base are constructed with a receiving groove for accommodating the cable. A rubber sheet is sleeved inside the receiving groove. The pressure cover is bolted to the top of the pressure plate seat. A rotating component is also connected between the pressure cover and the pressure plate seat.

[0005] This technical solution also fails to solve the problem of low disassembly and assembly efficiency, making it impossible to efficiently replace the gantry crane's electrical junction box when the gantry crane travels long distances.

[0006] Chinese patent CN110255377A discloses a guiding and protective device for the easily bent portion of a mobile gantry crane's power supply cable, belonging to the technical field of water conservancy and hydropower construction equipment. The aforementioned guiding and protective device for the easily bent portion of the mobile gantry crane's power supply cable includes an anchoring device, a guiding device, and a protective device. This invention uses an anchoring device to lift the power supply cable off the ground, preventing damage from friction with the ground; a guiding device to guide the power supply cable when it changes direction, preventing bending or coiling, eliminating collisions and friction between the cable and surrounding equipment, and requiring no manual assistance, reducing worker workload and eliminating safety hazards; and a protective device to effectively protect the cable and also to fix and limit its movement, preventing cable joint breakage.

[0007] This technical solution also fails to solve the problem of low disassembly and assembly efficiency, making it impossible to efficiently replace the gantry crane's electrical junction box when the gantry crane travels long distances. Utility Model Content

[0016] Preferably, the connecting post is located on the end of the limiting post near the cable trough, and the limiting component is located on the end of the base away from the cable trough. Along the arrangement direction of the limiting posts, the limiting post away from the cable trough is located between its corresponding connecting pipe and the limiting component.

[0017] Preferably, the limiting member includes a tube and a column. The tube is fixedly connected to the end of the base away from the cable groove. The axis of the tube extends vertically. One end of the column along its length is provided with a plug-in end. The column is plugged into the tube through the plug-in end. At this time, the other end of the column along its length protrudes from the top of the base and is used to limit the second column from disengaging along the axis of the first column.

[0018] Preferably, the other end of the column along its length is connected to the base by an iron chain, with one end of the iron chain welded to the base and the other end welded to one end of the column.

[0019] Preferably, the rotating assembly includes a movable plate, a limiting post located on one side of the movable plate, and a first sidewall and a second sidewall on the other side of the movable plate. The second sidewall is an arc-shaped wall. The plane of the first sidewall is parallel to the axis of the first column. One end of the second sidewall is connected to one end of the first sidewall, and the other end extends towards the cable trough. There are two fixing parts, which are respectively installed on the first sidewall and the second sidewall. The ends of the two fixing parts are flush with the ends of the first sidewall and the second sidewall, respectively. The thickness of the movable plate is less than the diameter of the connecting post.

[0020] Preferably, the fixing part is a fixing sleeve, which includes a first half and a second half. The first half and the second half have the same structure. The first half includes an arc-shaped part and a connecting part connected to both ends of the arc-shaped part. The arc-shaped part has a semi-circular structure. The two first halves are respectively connected to the first side wall and the second side wall through the arc-shaped part. The first half and the second half form a fixing hole that matches the cable through the arc-shaped part. The connecting part of the first half and the connecting part of the second half are connected by bolts.

[0021] Preferably, the base includes a first plate, a second plate, and multiple reinforcing plates. The first plate is arranged horizontally, and the second plate is arranged vertically and connected to the surface of the first plate. The reinforcing plates are right-angled trapezoidal structures.

[0022] Compared with the prior art, the beneficial effects of this application are:

[0023] 1. The first columnar component and the second columnar component of this application are connected by a plug-in method, which not only allows the rotating component to swing on the top of the base and provides protection for the cable when the gantry cable turns, but also allows the rotating component to disengage along the axial direction of the first columnar component after the limiting component is removed, which is convenient for disassembly and highly efficient. It can efficiently replace the gantry electrical box when the gantry is traveling a long distance.

[0024] 2. The limiting component of this application adopts the cooperation of a tube and a column. The installation is completed by inserting the column into the tube. During disassembly, it is only necessary to pull the column along the axial direction of the tube to release the limiting of the rotating component, which has high disassembly efficiency.

[0025] 3. In this application, the movable plate is provided with a first side wall and a second side wall. The fixing part on the first side wall can guide the cable to enter in a direction perpendicular to the cable groove, and the fixing part on the second side wall can guide the cable to be placed in the cable groove. The arc-shaped part of the second side wall between the two fixing parts can effectively prevent the cable from twisting and deforming significantly when turning.

[0026] 4. The height of the second plate in this application is greater than the height of the guardrail of the cable trough, so as to prevent the cable from being severely rubbed against the guardrail of the cable trough and worn when the cable is running. At the same time, this application also extends the rotating component so that the end of the rotating component near the cable trough extends to the top of the cable trough, so that the cable can be positioned in the middle of the cable trough.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] Example 1

[0039] refer to Figures 1-8 An auxiliary walking system for low-pressure large machinery in ports includes a base 1 and a rotating assembly 2. The base 1 is installed on one side of an external cable trough 3. A first columnar member 11 is provided on the base 1, and a second columnar member 21 is provided on the rotating assembly 2. The first columnar member 11 or the second columnar member 21 is provided with a through hole 112 for inserting and connecting the first columnar member 11 and the second columnar member 21, so that the rotating assembly 2 can swing on the top of the base 1.

[0040] The base 1 is also provided with a limiting member 12, which is detachably connected to the base 1. The limiting member 12 is used to restrict the second columnar member 21 from disengaging along the axial direction of the first columnar member 11.

[0041] The rotating assembly 2 is provided with multiple fixing parts 22 for fixing the cable, and the multiple fixing parts 22 are used to guide the cable to be placed on the cable groove 3.

[0042] It should be noted that the presence of a through hole 112 on the first columnar member 11 or the second columnar member 21 means that when the first columnar member 11 has a through hole 112, the second columnar member 21 can be inserted into the through hole 112 of the first columnar member 11. Similarly, when the second columnar member 21 has a through hole 112, the first columnar member 11 can be inserted into the through hole 112 of the second columnar member 21. However, regardless of whether the through hole 112 is located on the first columnar member 11 or the second columnar member 21, the movable component is the second columnar member 21, which is the rotating assembly 2.

[0043] In this embodiment, regarding installation, the operator first installs the base 1 on one side of the cable trough 3 according to the position of the cable trough 3. The specific installation method can be by fixing with bolts, etc. During installation, the axis of the first column 11 on the base 1 should be as perpendicular as possible to the length direction of the cable trough 3. Then, the rotating component 2 is installed on the first column 11. The rotating component 2 is limited by the limiting component 12 to restrict the second column 21 from detaching along the axial direction of the first column 11.

[0044] After all supporting components are installed, the cable is mounted on the rotating assembly 2 via the fixing part 22. The swinging motion of the rotating assembly 2 protects the gantry cable when it turns, and allows for efficient replacement of the gantry electrical box when the gantry moves a long distance. Simply remove the limiting part 12, and the rotating assembly 2 can be detached along the axis of the first column 11, which is convenient and quick. It should also be noted that for replacing the gantry electrical box, the base 1 needs to be installed beforehand using the above method. After removing the rotating assembly 2, it can be moved along with the cable to the target electrical box, and then the rotating assembly 2 can be installed on the base 1 using the above method.

[0045] In this embodiment, the first cylindrical member 11 includes a connecting pipe 111, a through hole 112 located on the connecting pipe 111, the connecting pipe 111 is fixedly connected to the top of the base 1 and is tangent to the plane of the top of the base 1, and the second cylindrical member 21 is inserted into the connecting pipe 111.

[0046] Specifically, the first cylindrical member 11 adopts a connecting tube 111, that is, the second cylindrical member 21 has a part that matches the through hole 112. The second cylindrical member 21 is inserted into the connecting tube 111, and the second cylindrical member 21 can swing around the axis of the connecting tube 111.

[0047] Furthermore, the second columnar member 21 includes a limiting post 211 and a connecting post 212. The limiting post 211 is fixedly connected to the side of the rotating assembly 2 away from the fixed part 22. One end of the connecting post 212 along its length direction is connected to one end of the limiting post 211 along its length direction. The axes of the connecting post 212 and the limiting post 211 coincide. The connecting post 212 matches the through hole 112. When the connecting post 212 is inserted into the connecting tube 111, the end face of the limiting post 211 is in contact with the end face of the connecting tube 111.

[0048] In practical use, the rotating assembly 2 is inserted into the connecting tube 111 via the connecting post 212. The function of the limiting post 211 is to limit the insertion depth of the connecting post 212. That is, when the connecting post 212 is inserted into the connecting tube 111, the limiting post 211 will fit against the end face of the connecting tube 111. The purpose of the limiting member 12 is to limit the movement of the second columnar member 21 along the axial direction of the first columnar member 11. Therefore, after the connecting post 212 and the connecting tube 111 are inserted, one end of the limiting post 211 is limited by contacting the end face of the connecting tube 111, while the other end is limited by the limiting member 12. Under the combined action of the connecting tube 111 and the limiting member 12, the connecting post 212 is prevented from disengaging from the connecting tube 111.

[0049] In this embodiment, there are two connecting pipes 111, which are arranged at intervals on the top of the base 1. The axes of the two connecting pipes 111 coincide. The number of limiting posts 211 matches the number of connecting pipes 111, and the positions of the limiting posts 211 and the connecting pipes 111 match. Each limiting post 211 is connected to a connecting post 212, and the two connecting posts 212 are respectively inserted into the corresponding connecting pipes 111.

[0050] Specifically, the two connecting pipes 111 paired with the two connecting posts 212 can distribute the weight of the rotating component 2 more evenly, making the rotating component 2 more stable. In other embodiments, more connecting pipes 111 can be used, but under the premise of meeting stability, the number of connecting pipes 111 should be as few as possible, as more will increase the installation difficulty of the rotating component 2.

[0051] In a preferred embodiment, for the use of two or more connecting pipes 111, only one limiting member 12 is required. Limiting only one limiting post 211 is sufficient to prevent the rotating assembly 2 from disengaging along the axial direction of the connecting pipe 111.

[0052] Preferably, the connecting post 212 is located on the end of the limiting post 211 near the cable trough 3, and the limiting member 12 is located on the end of the base 1 away from the cable trough 3. Along the arrangement direction of the limiting posts 211, the limiting post 211 away from the cable trough 3 is located between the corresponding connecting pipe 111 and the limiting member 12.

[0053] In practical use, to facilitate installation and disassembly by operators, the connecting post 212 is positioned at the end of the limiting post 211 near the cable trough 3. Therefore, the rotating assembly 2 is installed by aligning the connecting post 212 and the connecting pipe 111, and then pushing the rotating assembly 2 towards the cable trough 3 to connect the connecting post 212 and the connecting pipe 111. Similarly, during disassembly, after removing the limiting part 12, the rotating assembly 2 can be removed by pushing or pulling it away from the cable trough 3. The directions mentioned above, "towards the cable trough 3" and "away from the cable trough 3," refer to the axial direction of the connecting pipe 111.

[0054] In this embodiment, the limiting member 12 includes a tube 121 and a column 122. The tube 121 is fixedly connected to the end of the base 1 away from the cable groove 3. The axis of the tube 121 extends in the vertical direction. One end of the column 122 along its length direction is provided with a plug-in end 123. The column 122 is plugged into the tube 121 through the plug-in end 123. At this time, the other end of the column 122 along its length direction protrudes from the top of the base 1 and is used to limit the second column 21 from disengaging along the axial direction of the first column 11.

[0055] In use, the column 122 is inserted into the tube 121 from above through its plug end 123. The column 122 prevents the connecting column 212 from disengaging from the connecting tube 111. The column 122 is mainly positioned on the tube 121 by its own weight. When disassembling, the column 122 can be pulled out along the axis of the tube 121. This method not only has a limiting effect, but also makes disassembly and assembly very efficient.

[0056] Furthermore, the other end of the column 122 along its length is connected to the base 1 by an iron chain (not shown in the figure), one end of the iron chain is welded to the base 1, and the other end is welded to one end of the column 122.

[0057] In a specific implementation, by setting an iron chain, the column 122 and the base 1 can be integrated into one unit, avoiding the problem of the column 122 being lost after disassembly. Furthermore, by setting an iron chain, the disassembly efficiency can be further improved. Specifically, the column 122 can be pulled out by pulling the iron chain upward in the axial direction of the tube 121.

[0058] In this embodiment, the rotating assembly 2 includes a movable plate 23, a limiting post 211 located on one side of the movable plate 23, and a first sidewall 231 and a second sidewall 232 provided on the other side of the movable plate 23. The second sidewall 232 is an arc-shaped wall. The plane of the first sidewall 231 is parallel to the axis of the first column 11. One end of the second sidewall 232 is connected to one end of the first sidewall 231, and the other end extends toward the cable groove 3. There are two fixing parts 22, which are respectively installed on the first sidewall 231 and the second sidewall 232. The ends of the two fixing parts 22 are flush with the ends of the first sidewall 231 and the second sidewall 232, respectively. The thickness of the movable plate 23 is less than the diameter of the connecting post 212.

[0059] The limiting post 211 is set on one side of the surface of the movable plate 23, and the thickness of the movable plate 23 is less than that of the connecting post 212. This can improve the flexibility of the movable plate 23. It is fixedly connected to the top of the base 1 with the connecting pipe 111, and the connecting pipe 111 is tangent to the plane of the top of the base 1. This can give the movable plate 23 the maximum space to swing, so the movable plate 23 can swing in a range greater than 180 degrees.

[0060] Meanwhile, two fixing parts 22 are respectively connected to the first side wall 231 and the second side wall 232. The fixing part 22 on the first side wall 231 is used to guide the cable to enter in a direction perpendicular to the cable groove 3, while the fixing part 22 on the second side wall 232 is used to guide the cable to make an arc turn and be placed in the cable groove 3. When the cable turns, the two fixing parts 22, together with the second side wall 232, can prevent the cable from twisting. And the ends of the two fixing parts 22 are flush with the ends of the first side wall 231 and the second side wall 232, respectively, which can prevent the sharp corner of the movable plate 23 from contacting the cable and causing wear.

[0061] In this embodiment, the fixing part 22 is a fixing sleeve, which includes a first half 221 and a second half 222. The first half 221 and the second half 222 have the same structure. The first half 221 includes an arc-shaped part 2211 and a connecting part 2212 connected to both ends of the arc-shaped part 2211. The arc-shaped part 2211 has a semi-circular structure. The two first halves 221 are respectively connected to the first side wall 231 and the second side wall 232 through the arc-shaped part 2211. The first half 221 and the second half 222 form a fixing hole 223 that matches the cable through the arc-shaped part 2211. The connecting part 2212 of the first half 221 and the connecting part 2212 of the second half 222 are connected by bolts.

[0062] Specifically, the fixing sleeve is existing technology in this field and is also a conventional technical means for fixing cables. Therefore, the principle and fixing method of the fixing sleeve will not be explained in detail in this embodiment. However, it should be noted that, since there are two connecting parts 2212 in the first half 221 and two connecting parts 2212 in the second half 222, when the first half 221 and the second half 222 are connected, the connecting parts 2212 are connected in a one-to-one correspondence. Each pair of connecting parts 2212 can be connected by bolts; or two of the connecting parts 2212 can be hinged and the other two can be bolted.

[0063] Preferably, the base 1 includes a first plate 13, a second plate 14, and a plurality of reinforcing plates 15. The first plate 13 is arranged horizontally, the second plate 14 is arranged vertically and connected to the surface of the first plate 13, the reinforcing plates 15 are right-angled trapezoidal structures, the plurality of reinforcing plates 15 are connected between the first plate 13 and the second plate 14 and are located on both sides of the second plate 14, the top of the reinforcing plates 15 is flush with the top of the second plate 14, the first column 11 is connected to the top of the second plate 14, the top of the reinforcing plates 15 is used to limit the swing angle of the rotating assembly 2, the first plate 13 is provided with a plurality of mounting holes 131, the plurality of mounting holes 131 are used to connect bolts and fix the first plate 13 to a ground, the height of the second plate 14 is greater than the height of the guardrail of the cable trough 3, and the end of the rotating assembly 2 near the cable trough 3 extends to the top of the cable trough 3.

[0064] Specifically, the first plate 13 and the second plate 14 are perpendicular to each other. The two right-angled sides of the right-angled trapezoidal reinforcing plate 15 can be matched with the first plate 13 and the second plate 14. Therefore, the two right-angled sides of the reinforcing plate 15 are respectively between the first plate 13 and the second plate 14 to enhance the overall stability. Moreover, the top of the reinforcing plate 15 also has a limiting function to prevent the rotating component 2 from being damaged by its own weight after swinging.

[0065] The height of the second plate 14 is greater than the height of the guardrail of the cable trough 3, which prevents the cable from being severely rubbed against the guardrail of the cable trough 3 during the machine run and thus wears out the cable. At the same time, this application also extends the rotating component 2 so that the end of the rotating component 2 near the cable trough 3 extends to the top of the cable trough 3, which can position the cable in the middle of the cable trough 3.

[0066] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of this application, and these improvements or modifications should also be considered within the scope of protection of this application.
