Description

Technical Field

[0001] The utility model relates to the technical field of supporting equipment, in particular to an adjustable supporting tool for placing a tower body. Background Art

[0002] Quay cranes, also known as port cranes or quay cranes, are heavy machinery designed for loading and unloading cargo at seaports, river ports, or inland terminals. They play a vital role in the logistics chain, transferring cargo from ships to land-based transport vehicles and vice versa.

[0003] The crane tower is one of the main components of the wharf crane. The box-type shell of the crane tower needs to be painted during processing and manufacturing.

[0004] During spray painting operations, we often encounter situations where we need to use wooden blocks to elevate the tower shell to facilitate spray painting. In existing technology, during the crane production process at a manufacturing center, when tower bodies of varying specifications are brought into the paint room for spray painting, on-site construction workers typically find existing wooden blocks and place them under the tower backplate to elevate the tower for easier painting. However, due to the wide size of the wooden blocks, a large area where the backplate and the blocks come into contact is not exposed to paint.

[0005] In view of the above, it is necessary to propose an adjustable support tooling for tower placement to solve the above problems. Utility Model Content

[0025] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0026] Example 1

[0027] An adjustable support tool for tower placement, such as Figure 1-3 As shown, at least two sets of supporting tools 1 are provided at the bottom of the back plate of the tower shell 25, such as Figure 1 As shown, each set of supporting fixtures 1 is provided with at least two supporting structures 2, such as Figure 2As shown, in this embodiment, three groups of support structures 2 are set as an example. The support structure 2 is set on the sliding control structure 3, and the support structure 2 moves along its length direction on the sliding control structure 3 to adjust its position. It can be understood that by padding the bottom of the tower shell 25 with multiple groups of support tooling 1 and raising its bottom support, it is convenient to spray the bottom, and by improving the support structure 2 from a whole piece of wood to a block, the area blocked by the spraying can be reduced.

[0028] Specifically, the sliding control structure 3 in this embodiment includes a threaded rod 4, such as Figure 2 、 3 As shown, a support structure 2 is provided on the threaded section of the threaded rod 4. The support structure 2 includes a movable pad 5 and a positioning nut 6. The movable pad 5 can be made of nylon material in actual use, so as to reduce weight while obtaining a certain degree of softness in support. A through hole 7 is provided on the movable pad 5 for the threaded rod 4 to pass through. A certain number of movable pads 5 made of nylon are inserted into the threaded rod 4. In order to fix their positions, positioning nuts 6 are respectively provided on both sides of the movable pad 5 and screwed to the threaded rod 4. Limit baffles 8 are provided at both ends of the threaded rod 4. They are assembled onto the threaded rods on both sides in the order of bolt-moving pad 5-bolt, and then the limit baffles 8 are welded to both ends to prevent the bolts and nylon pads from falling off.

[0029] During the tower body spraying operation, the operator can adjust the movable pad 5 to the appropriate position according to the actual length of the tower body back plate, and then tighten the M36 positioning nuts 6 on both sides of the pad to fix the position of the nylon pad. Finally, the tower body is hoisted and placed on the adjusted tooling. Figure 1 After the tower body is hoisted after the spraying operation is completed, the positioning bolts can be screwed to both sides to restore the movable pad 5 to its active state. When the next tower body needs to be sprayed, it can be adjusted again to achieve the purpose of improving production efficiency and safety.

[0030] Example 2:

[0031] In the aforementioned embodiment, after spraying is completed, when it is necessary to spray the area blocked by the movable pad 5, it is necessary to first use a lifting equipment to lift the tower shell 25, suspend it, and provide safe support so that there is enough operating space underneath it. Then, the adjustment of each supporting structure 2 requires loosening the positioning nuts 6 on both sides, and then making room for the previous supporting area before spraying the blocked area. The operation is relatively cumbersome.

[0032] As an improvement, Figure 4 、 5As shown, the sliding control structure 3 includes a base plate 9, a screw drive unit 10, and a sliding track 11. In this embodiment, the support structure 2 is integrated on the base plate 9, and the screw drive unit 10 and the sliding track 11 are arranged parallel to the length direction of the base plate 9, that is, Figure 4 In the X-axis direction shown in FIG. 1 , the sliding track 11 is arranged along the X-axis, and the support structure 2 is slidingly arranged on the sliding track 11, so that the support structure 2 can be slidably adjusted in the X-axis direction. Figure 5 As shown, the support structure 2 includes a sliding block 15, which is composed of a slide plate 26 and a slider 27. The sliding rails 11 are arranged in parallel with each other. The slide plate 26 is arranged across the two sets of sliding rails 11 so that the slide plate 26 can be more stable. Correspondingly, two sliders 27 are provided at the bottom of the slide plate 26, corresponding to the two sliding rails 11 respectively, so that the slide plate 26 can move freely on the sliding rail 11; a screw block 16 connected to the threaded rod 4 is provided on one side of the sliding block 15. Specifically, the screw block 16 is fixedly connected to one end of the slide plate 26 for being screwed to the threaded rod 4, and its inner wall forms an internal thread structure;

[0033] Specifically, the support structure 2 is screwed to the screw drive unit 10, and the screw drive unit 10 controls the mirror-image movement of the two support structures 2 on the sliding track 11. In this embodiment, the screw drive unit 10 can directly control the support structures 2 on both sides to move their positions, so in actual use, after one spraying is completed, the screw drive unit 10 moves the two support structures 2 in a mirror-image manner by one position, exposing the originally obscured parts to facilitate subsequent supplementary spraying. In this embodiment, there is no need to use lifting equipment to lift the tower shell 25 into the air, which also avoids workers from operating at the bottom of the tower body for a long time, thereby improving safety. In addition, the support tooling 1 in this embodiment can always maintain support for the tower body, so there is no need to occupy a crane.

[0034] Specifically, the screw drive unit 10 includes two threaded rods 4. In this embodiment, the two threaded rods 4 are coaxially arranged and rotatably connected to the base plate 9. The two threaded rods 4 form semi-axial screws. The screw drive unit 10 also includes a drive box 28, which is arranged in the middle of the base plate 9. One end of the semi-axial screw is rotatably connected and extends into the drive box 28 to be provided with a bevel gear, and the other end is rotatably connected to the vertical plate 29 at the end of the base plate 9, thereby forming a rotational connection. Specifically, the two threaded rods 4 are each provided with a first screw near one end. A bevel gear 12 and a second bevel gear 13 are provided. The driving part also includes a driving bevel gear 14. The axial direction of the driving bevel gear 14 is set along the Y axis and is perpendicular to the two threaded rods 4, so that the driving bevel gear 14 is engaged with the first bevel gear 12 and the second bevel gear 13. The shaft of the driving bevel gear 14 is passed through the driving box 28 to set a handle (a motor drive can also be provided as power). The first bevel gear 12 and the second bevel gear 13 are rotated in opposite directions by rotating the handle, so that the screw block 16 engaged with the threaded rod 4 is moved in a mirror image.

[0035] Furthermore, the support structure 2 includes a fixed support member 17 fixedly mounted on the sliding block 15, and a lifting support member 18 mounted on the fixed support member 17 and capable of controlled lifting and lowering movement. A roller 19 is provided on one side of the fixed support member 17. When the lifting support member 18 is in a retracted position, the roller 19 rolls against the back plate. When the lifting support member 18 is in an extended position, the lifting support member 18 supports the back plate, disengaging the roller 19 from the back plate. In this embodiment, the lifting support member 18 is telescopically lifted and lowered within the fixed support member 17. A fixed side bracket 23 is provided axially extending from the fixed support member 17, and the roller 19 is rotatably connected to the fixed side bracket 23.

[0036] In actual use, when it is necessary to support the tower shell 25, the lifting support member 18 is raised to protrude from the upper end of the fixed support member 17, so that the top of the lifting support member 18 lifts the tower shell 25; when the spraying is completed and the supporting part needs to be sprayed, the synchronous lifting structure simultaneously controls the two lifting support members 18 to fall and retract into the fixed support member 17. At this time, the tower shell 25 falls on the roller 19, so that the support tooling 1 forms a rolling contact with the tower shell 25, as shown in FIG. Figure 4 、 5As shown, the upper part of the fixed support member 17 extends outward along the X-axis direction to form a fixed side bracket 23, and a roller 19 is rotatably set between the fixed side brackets 23 on both sides, so that the axial direction of the roller 19 is set along the Y-axis direction. Therefore, when the support structure 2 moves along the X-axis direction, the roller 19 can be used to form a rolling contact with the bottom of the back plate, and the roller 19 is long, which can better disperse the pressure. The rolling contact formed by the roller 19 and the bottom of the back plate can also make it easier for the screw drive unit 10 to control the moving position of the two support structures 2. When it moves into place, the lifting support is raised again, and the lifting support is used to support the tower shell 25 to form a stable support.

[0037] Specifically, such as Figure 5 As shown, the lifting support member 18 on the same supporting tooling 1 is controlled by a synchronous lifting structure 20. The synchronous lifting structure includes a spline shaft 21 that is axially rotated on the base, and the two ends of the spline shaft 21 are respectively rotatably connected to the vertical plates 29 at both ends. The rotation of the spline shaft 21 forms a driving control for the lifting support member 18. The spline shaft 21 is set through each fixed support member 17. A spline sleeve gear 22 is rotatably provided in the fixed support member 17. The inner wall of the spline sleeve gear 22 forms a spline sleeve that is slidably connected to the spline shaft 21, and the surface of the spline sleeve gear 22 forms a worm 32; thereby, the rotational torque of the spline shaft 21 can be transmitted to the fixed support member 17 through the worm 32. The spline sleeve gear 22 is slidably mounted on the spline shaft 21, and the spline sleeve gear 22 is used to drive the lifting support member 18 to move up and down; specifically, a driving screw 30 is arranged inside the fixed support member 17 along the Z-axis direction, and the driving screw 30 is rotatably arranged inside the fixed support member 17. A turbine is provided at the lower part of the driving screw 30, and the turbine is engaged with the worm 32. The screw on the upper part of the driving worm 32 is engaged with the lifting support member 18. The rotation of the fixed support member 17 inside the lifting support member 18 is restricted, so when the driving screw 30 rotates, the lifting support member 18 can be controlled to move up and down.

[0038] Example 3:

[0039] As an improvement to the second embodiment, a rotating side bracket 24 is rotatably provided on the fixed support member 17. Figure 6 、 7As shown, the roller 19 is rotatably connected to the rotating side bracket 24. In the second embodiment, the axial direction of the roller 19 is fixed along the Y-axis direction, which is not conducive to the movement control of the supporting tool 1 as a whole at the bottom of the tower shell 25 along the Y-axis direction. In this embodiment, a Y-axis track can be set at the bottom of the bottom plate 9 so that the supporting tool 1 as a whole can move along the Y-axis. Therefore, during the movement along the Y-axis, the axial direction of the roller needs to be adjusted to the X-axis direction. In this embodiment, the fixed side bracket 23 is changed to a rotating side bracket 24 that can rotate around the fixed support member 17. When the rotating side bracket 24 rotates, the roller can have the ability of universal adjustment, thereby facilitating the overall movement position of the supporting tool 1.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
