Description

Technical Field

[0001] This utility model relates to the field of fixed tooling technology, specifically to a rainproof shipping fixing device for a marine crane base column. Background Technology

[0002] Crane support columns refer to the supporting structure of a crane, typically composed of cylindrical columns. The design and function of the support columns vary depending on the type of crane.

[0003] Marine cranes are widely used on ships. After being manufactured by the factory, they need to be packaged and transported to the shipyard. During the ship's outfitting, the cranes are assembled. The crane's base column is shipped separately. The transportation of the crane and the waiting time for ship outfitting can be quite long. The crane's structure includes the load-bearing structure of the marine crane, such as the base column, tower, and boom. The base column is a cylindrical hollow structure. If rainy weather occurs during the long waiting time, rainwater can easily enter the base column. Once rainwater enters, it will have a significant impact on subsequent installation and use.

[0004] Nowadays, marine crane base columns are shipped separately. To protect the flange surface and interior of the base column, a wooden umbrella-shaped device is placed on the upper part of the base column, and a rainproof cloth is placed on top of it before shipping.

[0005] The crane column is shipped via open-air transport. Since the column has a hollow structure, a wooden umbrella-like device is required on the upper part of the column and covered with a tarpaulin to protect the internal structure from rain and snow and to protect the machined flange surface. However, this wooden umbrella-like device is simply placed on the column without any securing mechanism. It offers limited protection for the machined flange surface, and in strong winds, heavy rain, or other extreme weather conditions, the wooden umbrella-like device is easily damaged, providing no protection whatsoever for the column.

[0006] In view of the above, it is necessary to propose a rainproof shipping fixing device for marine crane base columns to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to solve the above-mentioned technical problems and provide a rainproof shipping fixing device for a marine crane base column.

The circular protective plate is fitted onto the flange surface, and a clamping bracket is provided on the upper side of the circular protective plate. The umbrella-shaped frame is based on the clamping bracket and forms a frame with the center protruding upward at the upper end of the crane base column. The umbrella-shaped frame has several diagonal bracing structures distributed radially in all directions. The center end of the diagonal bracing structure is connected to the center of the umbrella-shaped frame, and the edge end is connected to the edge of the upper end face of the base column, so that the umbrella-shaped frame forms a structure that is high in the center and low around the edges. The rainproof cloth is covered on the umbrella-shaped frame.

[0009] Furthermore, the circular protective plate is a ring-shaped or disc-shaped plate made of nylon material with a certain thickness.

[0010] Furthermore, the clamping bracket has a cross-shaped cross skeleton, and the ends of the clamping bracket overlap the circular protective plate. The flange hole on the flange surface, the circular protective plate and the clamping bracket are provided with fixing bolts. The ends of the clamping bracket are provided with waist holes for the fixing bolts to pass through.

[0011] Furthermore, the umbrella-shaped frame includes a central column, the lower end of which is fixedly positioned at the center of the compression support frame, and the central end of the diagonal brace structure is connected to the upper end of the central column.

[0012] Furthermore, the inclined support structure is a wooden umbrella rib, with the central end of the wooden umbrella rib hinged to the central column and the edge end overlapping the circular protective plate or the clamping bracket.

[0013] Furthermore, the diagonal bracing structure is arranged in several groups around the central column. Each group of diagonal bracing structures includes a winding part, a steel wire rope, and a hook part. The winding part is fixedly installed on the surface of the central column, and a steel wire rope is wound inside the winding part. An elastic element that applies tension to the steel wire rope is provided inside the winding part. The hook part is located at the end of the steel wire rope. The steel wire rope is pulled out from the winding part and hung on the edge of the flange surface through the hook part to form a diagonal steel wire.

[0014] Furthermore, the top of the central column is provided with a bundling device for guiding the wire ropes of each set of diagonal bracing structures. The bundling device includes a bundling disk, and the axial direction of the bundling disk is provided with a turning hole corresponding to the number of wire ropes. The winding part is located below the bundling disk, and the wire ropes are arranged to pass upward around the turning hole.

[0015] Furthermore, it also includes a tensioning device that simultaneously tensions all the wire ropes, the tensioning device including a fixing device that fixes all the wire ropes on the bundle disc, and an axial drive device that drives the bundle disc to move axially.

[0016] Furthermore, the fixing device includes a positioning ring disposed on the edge of the cluster disk, the positioning ring being fixedly sleeved on the edge of the cluster disk so that the wire rope passes around the upper edge of the fixing sleeve; it also includes a positioning disc that cooperates with the positioning ring, the lower side of the positioning disc having a first annular groove with an opening facing downwards, the positioning disc being axially moved and positioned relative to the cluster disk so that the first annular groove and the positioning ring clamp and position the wire rope.

[0017] Furthermore, the clustering device also includes a central sleeve, on which a clustering disk is disposed. The central sleeve is slidably mounted on a central column.

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0027] Example 1:

[0028] Currently, marine crane base columns are shipped separately, with only a simple wooden umbrella-shaped tarpaulin placed on the flange surface to protect the interior and flange. The base columns cannot be left exposed to the elements for extended periods, and electrical components inside the column cannot be shipped directly from within the column. This utility model proposes a rainproof shipping and securing device for marine crane base columns. Figure 1 As shown, the flange face 1 on the upper end of the base column 2 forms an installation plane, and also includes a circular protective plate 3 that mates with the flange face 1. The circular protective plate 3 is fitted onto the flange face 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 face 1, preventing damage to the flange face 1 during subsequent installation of this device.

[0029] Specifically, it also includes a clamping bracket 4, an umbrella-shaped frame, and a rainproof cloth (not shown in the figure). The clamping bracket 4 is installed 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 with the center protruding upward at the upper end of the crane base column 2. As an improvement, in this embodiment, the clamping bracket 4 can connect and fix the umbrella-shaped frame, the circular protective plate 3, and the flange surface 1. Specifically, the clamping bracket 4 is a cross-shaped frame, and the ends of the clamping bracket 4 overlap the circular protective plate 3. Figure 1As shown, in this embodiment, a cross-shaped clamping bracket 4 is made of C-shaped channel steel. Its four ends can overlap the flange face 1 and are fixed using fixing bolts 7. Specifically, fixing bolts 7 are provided through the flange holes on the flange face 1, the circular protective plate 3, and the clamping bracket 4. Each end of the clamping bracket 4 has a waist hole 8 for the fixing bolts 7 to pass through. The clamping bracket 4 can firmly position the umbrella-shaped frame and the circular protective plate 3 on the base column 2, providing a support and fixing platform for the umbrella-shaped frame; thus, it can be used for a long time with good fixing effect.

[0030] like Figure 1 As shown, the umbrella-shaped frame has several diagonal bracing structures 6 distributed radially in all directions. The central end of each diagonal bracing structure 6 is connected to the center of the umbrella-shaped frame, and the edge end is connected to the upper edge of the base column 2, making the umbrella-shaped frame high in the center and low around the edges. The rainproof cloth is placed on the umbrella-shaped frame. Specifically, the umbrella-shaped frame includes a central column 9, the lower end of which is fixedly located at the center of the clamping support frame, and the central end of each diagonal bracing structure 6 is connected to the upper end of the central column 9. The diagonal bracing structure 6 is a wooden umbrella rib 10, the central end of which is hinged to the central column 9, and the edge end overlaps the circular protective plate 3 or the clamping bracket 4. The rainproof cloth is placed on the umbrella-shaped frame and the edges are tied tightly, effectively protecting the interior of the base column 2. Therefore, after using this device, the base column 2 can be placed outdoors for a long time and transported. When conditions permit, the electrical installation components inside the base column 2 can be pre-installed before shipment, which can greatly save manpower and space costs.

[0031] Example 2:

[0032] The difference between this embodiment and the previous embodiment is that, Figure 2-6As shown, the diagonal bracing structure 6 is arranged in several groups around the central column 9. Each group of diagonal bracing structure 6 includes a winding part 11, a steel wire rope 12, and a hook part 13. The winding part 11 is fixedly installed on the surface of the central column 9. Since multiple groups of winding parts 11 need to be arranged circumferentially on the surface of the central column 9, in order to have sufficient arrangement space, in this embodiment, all winding parts 11 are arranged on the outer wall of a cylindrical disk with an enlarged diameter, thereby increasing the arrangement space and facilitating the arrangement of all winding parts 11 around the central column 9. Furthermore, a steel wire rope 12 is wound inside the winding part 11, and the winding part 11 is provided with a steel wire rope hook 13. The wire rope 12 is tensioned by an elastic element. The hook portion 13 is located at the end of the wire rope 12. The elastic element can be a coil spring. A winding frame that rotates around an axis is provided inside the winding portion 11. A coil spring with preloaded elastic stress is provided between the winding frame and the rotating axis. Thus, the elasticity of the coil spring can be used to wind the wire rope 12 into the winding portion 11. When the wire rope 12 is pulled out for use, the elasticity of the coil spring can be applied, thereby making the wire rope 12 even tighter. In use, the wire rope 12 is pulled out from the winding portion 11 and hooked onto the edge of the flange surface 1 through the hook portion 13 to form a diagonal tension wire. Figure 2 , 3 As shown in Figure 4, several steel wire ropes 12 are pulled out one by one and hung in the bottom of the flange hole through the hook part 13, thereby forming an umbrella-shaped skeleton body 5.

[0033] To allow the steel wire ropes 12 in the central and western sections to be pulled out in a concentrated manner, a bundling device 14 is provided at the top of the central column 9 to guide the steel wire ropes 12 of each set of diagonal bracing structures 6. The bundling device 14 includes a bundling disc 15, which has axially arranged turning holes 16 corresponding to the number of steel wire ropes 12. The winding section 11 is located below the bundling disc 15, and the steel wire ropes 12 are wound upwards around the turning holes 16. Figure 5 As shown, after the wire rope 12 passes through the turning hole 16, it can be tightened to form a downward turn. The center end of the wire rope 12 can be pulled out from near the center post 9 using the turning hole 16.

[0034] Because the tension of the steel wire rope 12 is insufficient when using it close to the elastic element, there is a chance that the steel wire rope 12 will be dented after being covered by a rainproof cloth. To improve the tautness of the steel wire rope 12 and enhance its rainwater drainage effect, a tensioning device 17 is provided to simultaneously tension all the steel wire ropes 12. After all the steel wire ropes 12 are pulled out, their center and edge ends are fixed, and then the tensioning device 17 simultaneously tightens the steel wire ropes 12. The tensioning device 17 includes a fixing device 18 that fixes all the steel wire ropes 12 to the bundle disc 15, and an axial drive device 19 that drives the bundle disc 15 to move axially. It is understood that, as... Figure 4 As shown, moving the cluster plate 15 upwards will simultaneously tighten all the steel wire ropes 12.

[0035] Specifically, the fixing device 18 includes a positioning ring 20 disposed on the edge of the cluster disk 15. The positioning ring 20 is fixedly sleeved on the edge of the cluster disk 15, allowing the wire rope 12 to pass around the upper edge of the fixing sleeve. After the wire rope 12 passes through the turning hole 16 and continues upward for a certain distance, it passes around the positioning ring 20 and then turns downward, so that the wire rope 12 is wrapped around the positioning ring 20. When the positioning ring 20 is clamped, the wire rope 12 can be clamped and positioned. 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 the opening facing downward. The positioning disk 21 moves axially and is positioned relative to the bundle disk 15. The positioning disk 21 is set to be able to move up and down. When the wire rope 12 is pulled out, the positioning disk 21 should be in the upper position. After all the wire ropes 12 are pulled out, the positioning disk 21 is moved down. At this time, the concave first annular groove 22 can be locked on the upper side of the surrounding wire ropes 12, while the corresponding positioning ring 20 is locked on the lower side of the wire rope 12, so that the first annular groove 22 and the positioning ring 20 clamp and position the wire rope 12. Furthermore, this embodiment also includes a drive nut 31 that drives the positioning disc 21 to move downward. An external thread 30 is provided at the upper end of the central sleeve 23, and the drive nut 31 is screwed to the external thread 30. When the drive nut 31 rotates, it can move up and down. The outer wall of the drive nut 31 is provided with a second annular groove 32, and a slip ring 33 is provided in the inner ring of the positioning disc 21. The slip ring 33 is rotatably set in the second annular groove 32. Therefore, the rotation of the drive nut 31 can press the positioning disc 21, thereby fixing the center end of the wire rope 12.

[0036] Furthermore, the clustering device 14 also includes a central sleeve 23, with a clustering disk 15 disposed on the central sleeve 23. The central sleeve 23 is slidably sleeved on the central column 9. The axial drive device 19 includes a central screw 24, which is coaxially rotatably connected to the top of the central column 9. The lower side of the inner wall of the central sleeve 23 forms a sliding sleeve portion 25, and the upper side forms an internal thread portion 26. The surface of the central column 9 is provided with an axial groove 27. The sliding sleeve portion 25 is provided with a sliding key 28 that cooperates with the axial groove 27. The internal thread portion 26 is screwed onto the central screw 24. The upper end of the central screw 24 is provided with a mushroom-shaped cap 29. Since the clustering device 14 is slidably mounted on the central column 9 via the central sleeve 23, the steel wire rope 12 can be further tightened when the clustering device 14 moves upward. To drive its movement, the central screw 24 is rotated, and the central screw 24 engages with the internal thread 26. The sliding key 28 on the lower side of the inner wall and the axial groove 27 limit the rotation of the clustering device 14. When the central screw 24 rotates, the clustering device 14 can be driven to move up and down. It can be understood that the usage steps are to first pull the steel wire rope 12, then position the central end of the steel wire rope 12 through the fixing device 18, and then rotate the central screw 24 to control the clustering device 14 to move upward and tighten the steel wire rope 12. Furthermore, this embodiment is provided with a mushroom-shaped top cover 29, the top of which has a smooth surface to prevent sharp objects from piercing the rainproof cloth. In order to drive the central screw 24 to rotate, multiple turning holes 34 are provided through it, and an F-wrench or the like can be inserted into them to control the rotation of the central screw 24.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
