Description

Technical Field

[0001] The utility model relates to the technical field of maintenance devices, in particular to a quay crane wire rope support hoop maintenance platform. Background Art

[0002] A quay crane (i.e., shore container crane) is a port mechanical equipment used for loading and unloading container ships at container terminals. It mainly relies on its own trolley to transfer containers from the cargo ship to the shore or from the shore to the cargo ship to realize the loading and unloading of containers. The trolley is divided into a self-propelled trolley and a towed trolley. Among them, the towed trolley uses a wire rope to pull the trolley to realize the straight-line back-and-forth movement of the trolley.

[0003] The existing quay crane uses a plurality of support hoops to support the wire rope when using the wire rope to pull the trolley, so as to reduce the wear of the wire rope. The support hoop is composed of a roller, a plastic roller sleeved on the roller, and end covers and bearings detachably installed at both ends of the roller. Since the hardness of the plastic roller is lower than that of the wire rope, and the wire rope runs under the action of the drum (also called a reel), the running track of the wire rope on the support hoop is wider (it moves axially on the support hoop when releasing or winding up). After a period of use, the support hoop will be worn and damaged, and needs to be replaced and repaired from time to time.

[0004] A quay crane contains several support hoops. For example, some quay cranes contain 18 large support hoops and 36 small support hoops. The rollers on each support hoop may wear to different degrees during use. When replacing and repairing them, it may be necessary to replace several support hoops of different specifications. It is inconvenient to carry and transfer several support hoops of different specifications, and the cost of replacing the support hoops as a whole is relatively high. Utility Model Content

[0026] In a typical implementation of the present invention, Figure 1 As shown, a quay crane wire rope support hoop maintenance platform is proposed, comprising: a base 1, on which a first storage bracket 3, a second storage bracket 4, a support hoop assembly fixing frame 5, a limit frame group and a push mechanism 8 are fixedly installed, wherein the first storage bracket 3 is fixedly arranged at a corner of the upper surface of the base 1 for placing a small-sized roller (i.e., a roller on a small support hoop); the second storage bracket 4 is fixedly arranged at a corner of the upper surface of the base 1, and the second storage bracket 4 is on the same side as the first storage bracket 3, for placing a large-sized roller (i.e., a roller on a large support hoop);

[0027] The support hoop assembly fixing frame 5 is fixedly set at a corner of the upper surface of the base 1 and is close to the second storage bracket 4. It is mainly used to accommodate the vertically placed support hoop during the support hoop assembly process and limit the support hoop as a whole; the pushing mechanism 8 is fixedly set at a corner of the upper surface of the base 1, and the pushing mechanism 8 is on the same side as the support hoop assembly fixing frame 5, and the limiting frame group is located between the pushing mechanism 8 and the support hoop assembly fixing frame 5. The damaged support hoop can be placed between the pushing mechanism 8 and the limiting frame group. The limiting frame group limits the position of the support hoop, and the pushing mechanism 8 is used to push the roller to separate the roller from the roller.

[0028] A plurality of legs 2 are fixedly provided at the bottom of the base 1 to support the base 1 through the legs 2, so that the fork arm of a forklift can be inserted into the bottom of the base 1 to transfer the maintenance platform as a whole through the forklift.

[0029] The first storage bracket 3 includes a first bracket body 31, which is a frame structure to reduce the overall weight. A plurality of support rod groups 32 are fixedly provided on both sides of the first bracket body 31. Each support rod group 32 includes two L-shaped support rods on the same side and at the same height. The two L-shaped support rods are used to support and limit the small rollers, so that the first storage bracket 3 can be used to store a plurality of small rollers.

[0030] The second storage bracket 4 includes a second bracket body 41, which is a rectangular frame structure. A plurality of limiting columns 42 are vertically fixed on the top of the second bracket body 41. The plurality of limiting columns 42 are arranged at intervals along the circumference of the second bracket body 41. Four adjacent limiting columns 42 arranged at four corners are used to limit a large roller, so that the second storage bracket 3 can be used to store a plurality of large rollers.

[0031] The support hoop assembly fixing frame 5 includes a first support seat 51 and a second support seat 52. The first support seat 51 and the second support seat 52 are both circular ring structures. The outer diameter of the first support seat 51 is smaller than the inner diameter of the second support seat 52. The thickness of the first support seat 51 is smaller than the thickness of the second support seat 52. The first support seat 51 and the second support seat 52 are coaxially arranged and both are fixedly installed on the base 1. The upper surfaces of the first support seat 51 and the second support seat 52 are provided with a plurality of bolt holes along the circumferential direction thereof for the detachable installation of the blocking rod 53.

[0032] The end of the blocking rod 53 is provided with an external thread, and can be vertically inserted and fixed on the first support seat 51 and the second support seat 52 by means of a threaded connection, so that the position of the roller is limited by the blocking rod 53, which facilitates the assembly of the roller and the installation of the bearing and the end cover at the end position of the support hoop. The first support seat 51 and its matching blocking rod 53 are used to limit the position of the small support hoop, and the second support seat 52 and its matching blocking rod 53 are used to limit the position of the large support hoop.

[0033] The inner diameters of the first support seat 51 and the second support seat 52 respectively match the outer diameters of the end covers at the ends of the support hoop of corresponding specifications, so as to facilitate limiting the position of the roller. Similarly, the diameter of the space enclosed by the baffle rods 53 on the first support seat 51 and the second support seat 52 matches the outer diameter of the roller on the corresponding support hoop.

[0034] It should be noted that during the assembly process, the blocking rod 53 is not installed on the first support seat 51 and the second support seat 52 at the same time, and the length of the blocking rod 53 on the first support seat 51 is different from the length of the blocking rod 53 on the second support seat 52.

[0035] The limit frame group includes a first limit frame 6 and a second limit frame 7 which are vertically arranged. The first limit frame 6 and the second limit frame 7 are arranged in sequence. The first limit frame 6 and the second limit frame 7 are both U-shaped frame structures with a vacant middle. The size of the first limit frame 6 is smaller than that of the second limit frame 7. The first limit frame 6 is used to limit the position of one end of the roller on the small support hoop, and the second limit frame 7 is used to limit the position of one end of the roller on the large support hoop. The first limit frame 6 is close to the support hoop assembly fixing frame 5, and the second limit frame 7 is close to the pushing mechanism 8.

[0036] The pushing mechanism 8 includes a column 81, which is fixed on the base 1. Two mounting holes 83 are vertically spaced apart on the column 81. The mounting hole 83 passes through the column 81. The two mounting holes 83 have different heights, and the two mounting holes 83 correspond to the middle gap of a limit frame respectively. Specifically, the two mounting holes 83 are coaxially arranged with the first limit frame 6 and the second limit frame 7 respectively. A push rod 82 is detachably installed in the mounting hole 83. A handle is fixed on one end of the push rod 82 away from the limit frame group. The push rod 82 can be used to push the roller of the support hoop. During the pushing process, the limit frame group is used to limit the position of the roller on the support hoop, so that the roller is separated from the corresponding roller to facilitate the replacement of the roller.

[0037] In this embodiment, the mounting hole 83 is a threaded hole structure, and the push rod 82 is a screw structure with an external thread. The push rod 82 is driven by rotating the push rod 82. In other embodiments, the mounting hole 83 can also be a through hole structure, and the push rod 82 is a rod-shaped structure with a smooth surface. The movement of the push rod 82 is controlled by directly pushing the push rod 82. The specific structure of the push rod 82 and the mounting hole 83 can be selected according to actual needs, and no excessive restrictions are made here.

[0038] The specific working principle is:

[0039] Use a forklift to move the maintenance platform as a whole to the quay crane to be maintained, and remove the damaged support hoop from the quay crane;

[0040] Remove the end caps and bearings at both ends of the removed support hoop, and place the roller and roller shaft to be replaced as a whole between the limit frame group and the push mechanism 8. When the support hoop is a large-sized support hoop, it is placed between the second limit frame 7 and the push mechanism 8. When it is a small-sized support hoop, it is placed between the first limit frame 6 and the push mechanism 8. The first limit frame 6 / second limit frame 7 is used to contact the end of the roller away from the push mechanism 8 to drive the push rod 82, and the push rod 82 is used to push the roller shaft, thereby realizing the separation of the roller and the roller shaft.

[0041] First, install the bearing and end cover at one end of the roller, and place the entire roller on the corresponding first support seat 51 / second support seat 52. Use the stop rod 53 to limit the position. Select the corresponding roller according to the size of the support hoop. Assemble the selected roller to the roller, then install the bearing and end cover at the other end, and reinstall the assembled support hoop on the quay crane.

[0042] The use of the maintenance platform enables the rollers of the support hoop to be quickly replaced on site, which facilitates the maintenance of the support hoop. There is no need to replace all the rollers, bearings, end covers, etc., which reduces maintenance costs. In addition, the maintenance platform can hold several rollers of different sizes to meet the maintenance needs of several support hoop of different specifications. It has strong overall adaptability and is convenient for the overall transfer of several rollers of different specifications.

[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
