[0034] This utility model provides a gantry crane maintenance platform, which solves the problems in related technologies where using aerial work platforms to maintain the hoist and track of a gantry crane is inconvenient, occupies equipment for a long time, and is costly.

[0035] See Figure 1 and Figure 2The diagram shows a gantry crane maintenance platform provided in this embodiment of the present invention. It may include: a first track beam 1, which has multiple first brackets 2. The first brackets 2 can be H-beams or box-beam structures. The multiple first brackets 2 are spaced apart along the extension direction of the first track beam 1 and are used to fix to multiple steel columns 7. The multiple first brackets 2 are supported by the first track beam 1. In this embodiment, the rebar processing area can be located on the ground, and multiple steel columns 7 are provided within the rebar processing area. Each steel column 7 can be fixed with one first bracket 2. Preferably, each first bracket 2 is at the same height from the ground, and the first track beam 1 can be fixed to the first brackets 2 away from the ground. One side; maintenance platform 3, the maintenance platform 3 includes a platform 31, the bottom of the platform 31 is provided with a sliding component 32, the sliding component 32 is slidably installed on the first track beam 1, that is, the platform 31 can slide along the extension direction of the first track beam 1, the maintenance personnel stand in the platform 31 at this time, and carry out maintenance on the track on which the gantry crane 5 runs as the platform 31 slides; and at least one traction rod 4, one end of the at least one traction rod 4 is detachably connected to the platform 31, the other end of the traction rod 4 is used to detachably connect to the gantry crane 5, the two ends of the traction rod 4 are respectively connected to the gantry crane 5 and the platform 31, when the gantry crane 5 runs on the track on the steel column 7, it can pull the platform 31 through the traction rod 4.

[0036] See Figure 2 As shown, in some optional embodiments, two traction rods 4 are provided, which are respectively set on opposite sides of the gantry crane 5. The two traction rods 4 make it easier to pull the platform 31. Each traction rod 4 has a connecting part 41 at both ends. One connecting part 41 of each traction rod 4 is hinged to the first traction base 311 of the platform 31, and the other connecting part 41 is hinged to the second traction base 312 fixed on one side of the gantry crane 5. During the process of the gantry crane 5 pulling the traction rod 4 and the traction rod 4 pulling the platform 31, the part of the connecting part 41 that connects the first traction base 311 and the second traction base 312 is set to be hinged, which makes the movement of the traction rod 4 more flexible and less prone to breakage.

[0037] See Figure 4 and Figure 5As shown, in some optional embodiments, the traction rod 4 includes a connecting pipe 42 and two adjusting rods 43. The connecting pipe 42 is a hollow structure, and the two adjusting rods 43 are coaxially inserted at both ends of the connecting pipe 42. The adjusting rods 43 are threadedly engaged with the connecting pipe 42, that is, the surface of the adjusting rods 43 and the inside of the connecting pipe 42 can be provided with threads. The length of the adjusting rods 43 extending out of the connecting pipe 42 is adjusted by screwing them in the connecting pipe 42, that is, the length of the entire traction rod 4 is adjusted. Preferably, nuts can be fixed at both ends of the connecting pipe 42. In this case, the adjusting rods 43 with threads on their surfaces are engaged with the nuts. The connecting part 41 includes a connecting ear plate 411. The connecting ear plate 411 is fixed with the adjusting rods 43. The connecting ear plate 411 can be provided with through holes. The first traction base 311 and the second traction base 312 are also provided with through holes to engage with it. The bolts and nuts passing through the through holes achieve hinged connection and also facilitate the removal of the adjusting rods 43 from the gantry crane 5 and the platform 31.

[0038] In some optional embodiments, the first track beam 1 has a first track, and the sliding assembly 32 includes two sets of moving parts 321 spaced apart at the bottom of the platform 31 along the extension direction of the first track beam 1. Each set of moving parts 321 includes two rollers 3211 and an axle 3212 connecting the two rollers 3211. The axle 3212 is connected to the platform 31. The axis of the rollers 3211 is perpendicular to the first track, and the rollers 3211 are adapted to roll on the first track. That is, the platform 31 slides on the first track beam 1 by the cooperation of the rollers 3211 and the first track, so that the rollers 3211 roll along the first track to change the position of the platform 31 in the first track beam 1. In some other embodiments, the platform 31 can also slide in the first track beam 1 by setting a groove in the first track beam 1, and setting a slider at the bottom of the platform 31 that cooperates with the groove.

[0039] See Figure 6As shown, preferably, the bottom of the platform 31 is provided with at least two mounting seats 322 at intervals. The axle 3212 passes through the two mounting seats 322 and can be fixed to the mounting seats 322. The bottom of the mounting seat 322 is provided with a limiting groove, and part of the roller 3211 is located in the limiting groove, that is, part of the roller 3211 can extend beyond the bottom surface of the mounting frame. Preferably, four rollers 3211 are provided. Two rollers 3211 arranged perpendicular to the extension direction of the first track beam 1 are connected by the axle 3212. Two first track beams 1 can be provided, and the two first track beams 1 are arranged in parallel. The first track beam 1 can be close to the steel column 7. The side view is considered as the first side, and the side away from the steel column 7 is considered as the second side. The first track beam 1 on both the first and second sides is provided with two rollers 3211. The two rollers 3211 on the same side can be located in the limiting groove of the same mounting seat 322. Both first track beams 1 can be H-beams or box beams. The first track beam 1 is provided with at least two limiting plates 12. The two limiting plates 12 are adapted to abut against the opposite sides of the two mounting seats 322 respectively. The limiting plates 12 can contact the mounting seats 322 or be spaced apart from the mounting seats 322. The limiting plates 12 can protect the platform 31 from the rollers 3211 from sliding off the first track beam 1 during the sliding process of the first track beam 1.

[0040] See Figure 3 As shown, in some optional embodiments, the platform 31 includes a platform 33, which is disposed on opposite sides of the sliding component 32 along with the first track beam 1. Preferably, a platform panel 36 can be added on the side of the platform 33 away from the sliding component 32 to further increase the safety of the platform 31. In some embodiments, the first traction base 311 can be disposed on the upper surface of the mounting base 322, in which case the surfaces of the platform 33 and the platform panel 36 are provided with perforations through which the first traction base 311 can pass. A fixed guardrail 34, comprising multiple crisscrossing fixed bars, is provided to protect the safety of maintenance personnel during maintenance. A lifting guardrail 35 is installed on the side of the platform 33 closest to the steel column 7. Since the guardrail on the side closest to the steel column 7 is a lifting guardrail 35, it can be lowered when the platform 31 encounters a structure on the steel column 7 that obstructs its movement, thus preventing obstruction. Both the fixed guardrail 34 and the lifting guardrail 35 have a certain height to protect the safety of maintenance personnel. The fixed guardrail 34 and the lifting guardrail 35 are located on opposite sides of the platform 33. In some other embodiments, guardrails may also be installed on the other two sides of the platform 33.

[0041] In some optional embodiments, the lifting guardrail 35 includes: a lifting railing and a sensing device disposed on one side of the lifting railing. The sensing device is installed on the side of the lifting railing away from the platform 33. In this embodiment, the sensing device is set as a light sensor. When the sensing device senses a change in the brightness of the light, it automatically raises and lowers. During the raising and lowering process of the lifting railing, the height of the raising and lowering is limited, that is, when the lifting railing is lowered to the lowest point, it also has a height that can protect maintenance personnel. In some other embodiments, the lifting guardrail 35 can also be set as manually adjustable. When encountering a structure set on the steel column 7 that obstructs the operation of the maintenance platform 3, the height of the lifting guardrail 35 can be manually lowered to allow smooth passage.

[0042] Preferably, the gantry crane maintenance platform further includes: stiffening plate 6, which is disposed at the first bracket 2 for fixing to the steel column 7. Multiple stiffening plates 6 can be disposed at the positions where the first bracket 2 and the steel column 7 are subjected to relatively concentrated forces, in order to increase the stress strength of the first bracket 2.

[0043] This utility model embodiment also provides a gantry crane maintenance system, which may include: at least two rows of steel columns 7, each row of steel columns 7 is provided with a second track beam 71, the second track beam 71 extends along the extension direction of the first track beam 1, in some optional embodiments, the lower part of the second track beam 71 may also be provided with multiple second brackets 73 for supporting the second track beam 71, each second bracket 73 is fixed to the steel column 7, so that the fixation between the second track beam 71 and the steel column 7 is more secure, the second bracket 73 is preferably H-beam or box beam; gantry crane 5, the gantry crane 5 spans across at least two rows of steel columns 7, the gantry crane 5 is slidably installed on the second track beam 71, that is, multiple rows of steel columns 7 are set in the steel bar processing yard, the gantry crane 5 spans across the second track beam 71 of two adjacent rows of steel columns 7, the bottom of the second track beam 71 may be provided with second brackets 73 for support; first track beam 1 The first track beam 1 is located below the second track beam 71. The first track beam 1 is provided with a plurality of first brackets 2, which are spaced apart along the extension direction of the first track beam 1. Each first bracket 2 is fixed to a single steel column 7 of each row of steel columns 7, and the plurality of first brackets 2 are supported on the first track beam 1. The maintenance platform 3 includes a platform 31, and a sliding component 32 is provided at the bottom of the platform 31. The sliding component 32 is slidably installed on the first track beam 1. The maintenance platform 3 includes at least one traction rod 4, one end of which is detachably connected to the platform 31, and the other end of which is detachably connected to the gantry crane 5. In this embodiment, except for the gantry crane 5, the steel columns 7, and the second track beam 71 provided on the steel columns 7, its structure is the same as the gantry crane maintenance platform described above, and will not be described again here.

[0044] Preferably, the surface of the second track beam 71 is provided with conductive slide rails 72, and the end of the gantry crane 5 near the second track beam 71 is provided with an electric slider 52 that cooperates with the conductive slide rails 72. The sliding method of the gantry crane 5 on the second track beam 71 can also be other common sliding structures.

[0045] This utility model embodiment provides a gantry crane maintenance platform and maintenance system. Since the bottom of the platform 31 is equipped with rollers 3211, the rollers 3211 and the first slide rail can cooperate. The first track beam 1 extends along the direction of multiple steel columns 7. When the gantry crane 5 slides along the electric slide rail on the steel columns 7, the traction rod 4 set on the gantry crane 5 is also pulled. The other end of the traction rod 4 is connected to the platform 31, that is, connected to the maintenance platform 3. The maintenance platform 3 is pulled by the traction rod 4 and slides along the first track beam 1. Therefore, maintenance personnel can be pulled on the maintenance platform 3 to maintain the running track of the gantry crane 5. The fixed guardrail 34 and the lifting guardrail 35 can protect the safety of maintenance personnel. The limit plate 12 can further prevent the rollers 3211 from sliding off the first slide rail. The detachable traction rod 4 can facilitate maintenance personnel to maintain multiple rows of steel columns 7 in the steel bar processing yard, saving materials and reducing some installation steps.

[0046] When using the gantry crane maintenance platform and system to inspect the hoist 8 and the running track of the gantry crane 5, the specific installation process of the maintenance platform can be as follows:

[0047] First, select the specifications and materials of each component in the maintenance platform 3 according to the actual maintenance needs, and then assemble them. Based on the weight of the assembled maintenance platform 3 and the span of each row of 7 steel columns, select appropriate first track beam 1 and second track beam 71. Before installing the first track beam 1 onto the steel columns 7, the limiting plate 12 needs to be welded in advance. Then, based on the weight of the maintenance platform 3 and the first track beam 1, select appropriate first bracket 2. At a certain height below the gantry crane 5, weld the first bracket 2 to the side of the steel column 7. The steel column 7 and the first corbel 2 are subjected to concentrated stress. A certain number of stiffening plates 6 can be welded at the locations where the stress is concentrated. Then, the hoist 8 in the steel bar processing yard is used to hoist the first track beam 1 to the design position. With the assistance of maintenance personnel, the installation and fixation of the first track beam 1 is completed. After that, the hoist 8 is used again to hoist the maintenance platform 3 to the design position for temporary fixation. The maintenance platform 3 is then used to install the second traction base 312 in the gantry crane 5. Finally, the traction rod 4 is connected to the gantry crane 5 and the maintenance platform 3 respectively. When installing the maintenance platform 3, the installation steps can be as follows: first, complete the connection and fixation of the roller 3211 and the axle 3212. Then, assemble the axle 3212 and the roller 3211 to the mounting base 322 and fix the mounting base 322 to the station plate 33. Then, lay the platform panel 36 in the station plate 33. Finally, fix the guardrail 34 and the lifting guardrail 35 on the side of the station plate 33.

[0048] When using the gantry crane maintenance platform and system to inspect the hoist 8 and the running track of the gantry crane 5, the specific maintenance method may be:

[0049] First, maintenance personnel enter the maintenance platform 3. Then, the gantry crane 5 is intermittently started and stopped, causing it to move intermittently along the second track beam 71. Simultaneously, maintenance personnel perform maintenance work on the corresponding side of the hoist 8 and conductive slide rail 72 on the maintenance platform 3. After completing maintenance work on one side, the maintenance personnel leave the maintenance platform 3 and use the hoist 8 to lift it to the first track beam 1 on the other side. The traction rod 4 is then installed. After completing maintenance work on the other side, the traction rod 4 is disassembled, and the maintenance personnel leave the maintenance platform. The maintenance platform 3 is then lowered to the ground or temporarily fixed to the first track beam 1, awaiting the next maintenance operation. Maintenance personnel can enter the maintenance platform 3 either through a ladder structure installed between the steel columns 7 or by using an external ladder. Intermittent start-stop gantry crane 5 means that by intermittently starting and stopping the operation of gantry crane 5, gantry crane 5 can move intermittently in the second track beam 71 and can stop at the corresponding position of the second track beam 71, which facilitates maintenance personnel to carry out maintenance operations. In other words, the maintenance process of maintenance personnel is actually carried out section by section.
