Description

Technical Field

[0001] The invention relates to the technical field of fixing tooling, in particular to a rainproof shipping fixing device for a base column of a marine crane. Background Art

[0002] Crane foundation refers to the supporting structure of the crane, usually composed of cylindrical columns. Depending on the type, the design and function of the foundation vary.

[0003] Marine cranes are widely used on ships. After being manufactured by the manufacturer, the marine cranes need to be packaged and transported to the shipyard. The cranes will be assembled when the ship is outfitted. The crane base columns are shipped separately, and it takes a long time to transport the cranes and wait for the ship to be outfitted. The structure of the crane includes the load-bearing structure of the marine crane, including the base column, tower body, boom, etc. The base column is a cylindrical hollow structure. During the long waiting time, if it encounters rainy weather, rainwater is easy to enter the inside of the base column. Once rainwater enters, it will have a greater impact on the subsequent installation and use.

[0004] Nowadays, the base columns of marine cranes are all delivered separately. In order to protect the flange surface and the interior of the base column, a wooden umbrella rib device is placed on the top of the base column, and it is covered with a rainproof cloth before delivery.

[0005] The crane base column is shipped in the open air. The base column is a hollow structure. In order to protect the inside of the base column from rain and snow erosion and to protect the machine flange surface, a wooden umbrella-shaped device needs to be placed on the upper part of the base column and covered with a rainproof cloth. However, the wooden umbrella-shaped device is simply placed on the base column without a fixing device. The protection of the machine flange surface is limited, and in special weather with strong winds and heavy rains, the wooden umbrella-shaped device is very easy to be damaged, and the protection of the base column is completely lost.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Embodiment 1: Existing ship crane base columns are all shipped separately, and only a wooden umbrella rib cover rain cloth is simply placed on the flange surface of the base column to protect the inside of the base column and the flange surface. The base column cannot be placed in the open air for a long time, and the electrical installation parts in the base column cannot be installed in the base column for shipment. The present invention provides a rainproof shipping fixing device 18 for a ship crane base column 2, such as Figure 1 As shown, the flange surface 1 on the upper end surface of the base column 2 forms a mounting plane, and also includes a circular protective plate 3 matched with the flange surface 1. The circular protective plate 3 is fitted on the flange surface 1. Specifically, the circular protective plate 3 is a ring-shaped or disc-shaped plate made of nylon material with a certain thickness. The circular protective plate 3 can protect the flange surface 1, and in the subsequent installation of the device, the flange surface 1 can be prevented from being damaged.

[0022] Specifically, it also includes a clamping bracket 4, an umbrella-shaped frame, and a rainproof cloth (not shown in the figure). A clamping bracket 4 is arranged on the upper side of the circular protective plate 3. The umbrella-shaped frame is based on the clamping bracket 4 and forms a frame body with a central upward protrusion at the upper end of the crane base column 2. As an improvement, in this embodiment, the umbrella-shaped frame, the circular protective plate 3 and the flange surface 1 can be connected and fixed by the clamping bracket 4. Specifically, the clamping bracket 4 is a cross-shaped cross frame body, and the ends of the clamping bracket 4 are overlapped on the circular protective plate 3, such as Figure 1As shown, in this embodiment, a cross-shaped clamping bracket 4 is made of C-shaped channel steel, and its four ends can be overlapped on the flange surface 1 and fixed with fixing bolts 7. Specifically, fixing bolts 7 are provided through the flange holes on the flange surface 1, the circular protection plate 3 and the clamping bracket 4, and waist holes 8 for the fixing bolts 7 to pass through are provided at the ends of the clamping bracket 4. The clamping bracket 4 can firmly position the umbrella-shaped frame and the circular protection plate 3 on the base column 2, and provide a supporting and fixing platform for the umbrella-shaped frame; thus, it can be used for a long time with a good fixing effect.

[0023] like Figure 1 As shown, the umbrella-shaped frame is radially distributed with a plurality of diagonal bracing structures 6, the central end of the diagonal bracing structure 6 is connected to the center of the umbrella-shaped frame, and the edge end is connected to the edge of the upper end surface of the base column 2, so that the umbrella-shaped frame forms a structure with a high center and low surroundings, and the rainproof cloth cover is arranged on the umbrella-shaped frame. Specifically, the umbrella-shaped frame includes a central column 9, the lower end of the central column 9 is fixedly arranged at the central position of the clamping support frame, and the central end of the diagonal bracing structure 6 is connected to the upper end of the central column 9. The diagonal bracing structure 6 is a wooden rib 10, the central end of the wooden rib 10 is hinged on the central column 9, and the edge end is overlapped on the circular protective plate 3 or the clamping support 4. The rainproof cloth cover is on the umbrella-shaped frame and the edge is tied tightly. After the rainproof cloth is covered, the inside of the base column 2 can be effectively protected. Therefore, after using this device, the base column 2 can be placed and transported in the open air for a long time. If conditions permit, the electrical installation parts in the base column 2 can be pre-installed in place before shipment, which can greatly save manpower and space costs.

[0024] Embodiment 2: The difference between this embodiment and the above-mentioned embodiment is that Figure 2-6As shown, the diagonal brace structure 6 is provided with several groups around the central column 9, and each group of diagonal brace structures 6 includes a reeling portion 11, a steel wire rope 12, and a hook portion 13. The reeling portion 11 is fixedly arranged on the surface of the central column 9. Since multiple groups of reeling portions 11 need to be arranged circumferentially on the surface of the central column 9, in order to have sufficient layout space, in this embodiment, all the reeling portions 11 are arranged on the outer wall of the cylindrical disk with an enlarged diameter, so that the layout space can be increased, which is convenient for all the reeling portions 11 to be arranged around; further, a steel wire rope 12 is wound in the reeling portion 11, and a pair of steel wire ropes 12 are arranged in the reeling portion 11. The elastic member that applies tension to the wire rope 12, the hook portion 13 is arranged at the end of the wire rope 12, the elastic member can be a coil spring, a coil frame that rotates around the axis is arranged in the coiling portion 11, and a coil spring with preloaded elastic stress is arranged between the coiling frame and the rotating shaft, so that the wire rope 12 can be wound in the coiling portion 11 by using the elasticity of the coil spring. When the wire rope 12 is pulled out for use, the elasticity of the coil spring can also be loaded, and then the wire rope 12 is tightened by using the elasticity. When in use, the wire rope 12 is pulled out from the coiling portion 11 and hung on the edge of the flange surface 1 through the hook portion 13 to form an oblique steel wire. Figure 2 , 3 As shown in FIG. 4 , a plurality of steel wire ropes 12 are pulled out one by one and hung in the bottom of the hole of the flange through the hook portion 13 , thereby forming an umbrella-shaped frame body 5 .

[0025] In order to pull out the steel wire ropes 12 in the middle and west, a bundling device 14 is provided on the top of the central column 9 to guide the steel wire ropes 12 of each group of diagonal bracing structures 6. The bundling device 14 includes a bundling disk 15. The axial direction of the bundling disk 15 is provided with turning holes 16 corresponding to the number of steel wire ropes 12. The reeling part 11 is arranged below the bundling disk 15, and the steel wire ropes 12 are arranged to bypass the turning holes 16 upward. Figure 5 As shown, after the steel wire rope 12 passes through the turning hole 16 , it is tightened to form a downward turn, and the center end of the steel wire rope 12 can be pulled out from near the center column 9 using the turning hole 16 .

[0026] Since the tensioning force of the steel wire rope 12 is insufficient when the elastic member is in use, there is a possibility that the steel wire rope 12 will be dented after being covered with the rainproof cloth. In order to tighten the steel wire rope 12 and achieve a better rainwater diversion effect, as an improvement, a tensioning device 17 is provided to simultaneously tension all the steel wire ropes 12. When all the steel wire ropes 12 are pulled out, their center ends and edge ends are fixed, and then the steel wire ropes 12 are simultaneously tightened by the tensioning device 17. The tensioning device 17 includes a fixing device 18 that fixes all the steel wire ropes 12 on the clustering disk 15, and also includes an axial driving device 19 that drives the clustering disk 15 to move axially. It can be understood that, if Figure 4 As shown, all the steel wire ropes 12 can be tightened simultaneously by moving the clustering disc 15 upward.

[0027] Specifically, the fixing device 18 includes a positioning ring 20 arranged on the edge of the clustering disk 15, and the positioning ring 20 is fixedly sleeved on the edge of the clustering disk 15, so that the wire rope 12 is arranged around the upper edge of the fixing sleeve. After the wire rope 12 passes through the turning hole 16 and continues to move upward for a distance, it passes around the positioning ring 20 and then turns downward, so that the wire rope 12 is wound around the positioning ring 20. When the positioning ring 20 is clamped, the clamping and positioning of the wire rope 12 can be achieved; it also includes a positioning disk 21 that cooperates with the positioning ring 20, such as Figure 6 As shown, the lower side of the positioning disk 21 is provided with a first annular groove 22 with an opening facing downward. The positioning disk 21 is axially moved and positioned relative to the clustering disk 15. The positioning disk 21 is configured to be movable up and down. When the wire rope 12 is pulled out, the positioning disk 21 should be located at the upper position. After all the wire ropes 12 are pulled, the positioning disk 21 is moved downward. At this time, the concave first annular groove 22 can be clamped on the upper side of the surrounding wire ropes 12, and the corresponding positioning ring 20 side is clamped on the lower side of the wire rope 12, so that the first annular groove 22 and the positioning ring 20 form a clamping positioning for the wire rope 12. Furthermore, in this embodiment, a driving nut 31 is provided for driving the positioning disk 21 to move downward. An external thread 30 is provided at the upper end of the center sleeve 23, and the driving nut 31 is threadedly connected to the external thread 30. When the driving nut 31 is rotated, it can move up and down. A second annular groove 32 is provided on the outer wall of the driving nut 31, and a slip ring 33 is provided on the inner ring of the positioning disk 21. The slip ring 33 is rotatably arranged in the second annular groove 32, so the positioning disk 21 can be pressed by rotating the driving nut 31, thereby fixing the center end of the wire rope 12.

[0028] Furthermore, the bundling device 14 also includes a center sleeve 23, the bundling disk 15 is arranged on the center sleeve 23, the center sleeve 23 is slidably sleeved on the center column 9, the axial drive device 19 includes a center screw 24, the center screw 24 is coaxially rotatably connected to the top of the center column 9, a sliding sleeve portion 25 is formed on the lower side of the inner wall of the center sleeve 23, and an internal thread portion 26 is formed on the upper side, an axial groove 27 is provided on the surface of the center column 9, the sliding sleeve portion 25 is provided with a sliding key 28 matching the axial groove 27, the internal thread portion 26 is screwed on the center screw 24, and a mushroom top cover 29 is provided on the upper end of the center screw 24. Since the bunching device 14 is slidably mounted on the center column 9 through the center sleeve 23, the steel wire rope 12 can be further tightened when the bunching device 14 moves upward. To drive its movement, the center screw 24 is rotated, and the center screw 24 is meshed with the internal threaded portion 26, and the sliding key 28 and the axial groove 27 on the lower side of the inner wall limit the rotation of the bunching device 14. When the center screw 24 rotates, the bunching device 14 can be driven to move up and down. It can be understood that the use steps are to first pull the steel wire rope 12, then position the center end of the steel wire rope 12 through the fixing device 18, and then rotate the center screw 24 to control the bunching device 14 to move upward to tighten the steel wire rope 12. Further, in this embodiment, a mushroom top cover 29 is provided, and its top is a smooth surface to prevent sharp objects from piercing the rainproof cloth. In order to drive the center screw 24 to rotate, a plurality of screw holes 34 are provided on it, and an F wrench or the like can be inserted therein to control the rotation of the center screw 24.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
