Description

Technical Field

[0001] This utility model relates to the technical field of ship repair and construction operation platforms, and in particular to a ship repair and construction operation platform. Background Technology

[0002] In the process of shipbuilding and repair, it is usually necessary to work at height. In existing technology, this is usually achieved by using a construction work platform.

[0003] A search revealed a utility model patent with publication number CN220410852U, which discloses a ship repair and construction operation platform. This platform, belonging to the field of operation platform technology, includes self-locking casters, a base, a liftable and extendable ship repair and construction operation platform, and a positioning component. The liftable and extendable platform facilitates the raising and lowering of the main operation platform and the extended operation platform, meeting the needs of construction operations at different heights. A second protective rail slides within the first protective rail, ensuring that when the extended operation platform is extended, both the first and second protective rails still protect the entire platform, guaranteeing operational safety. The self-locking casters facilitate movement of the platform, and the positioning component helps to fix its position, thus better ensuring the stability of the operation platform.

[0004] The ship repair and construction operation platform in the aforementioned patent can be fixed by positioning components during use. However, when fixing the operation platform, it can only be supported on both sides near the base, resulting in a relatively small support range and insufficient stability. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a ship repair and construction operation platform that can effectively expand the support range of the work platform, make the support of the work platform more stable, and improve the stability. Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ship repair and construction operation platform, comprising a base, a support assembly, and an adjustment mechanism. Four sets of self-locking casters are fixedly installed at the bottom of the base, and a liftable and expandable ship repair and construction operation platform is provided at the top of the base. The support assembly includes four sets of sleeves, which are rotatably fitted onto four sets of guide columns within the liftable and expandable ship repair and construction operation platform. The bottom ends of the sleeves and support arms are in contact with the top of the base. Support arms are integrally fixedly connected to the outer walls of each of the four sets of sleeves, and threaded support columns are screwed onto the support arms. A sleeve seat is fixedly connected to the top of the threaded support column, and two sets of handles are symmetrically fixedly connected to the sleeve seat. A support is fixedly connected to the bottom of the threaded support column, and the support arm… A groove is provided on the side of the bottom away from the sleeve, and the groove is located directly above the support. The depth of the groove is slightly greater than the thickness of the support. The adjustment mechanism includes a transmission rod for adjusting the support position of the support. Extension plates are integrally connected to both ends of the base. Support plates are fixedly connected to the top of both sets of extension plates. The transmission rod is rotatably mounted on the two sets of support plates. A handwheel is fixedly connected to the right end of the transmission rod. Worm shaft sections are integrally provided on both sides of the outer wall of the transmission rod. Four sets of rotating shafts are symmetrically rotatably connected to the top of the base. Worm wheels are fixedly connected to the top of the four sets of rotating shafts, and the four sets of worm wheels mesh with the two sides of the two sets of worm shaft sections respectively. A driving gear is fixedly sleeved on each of the four sets of rotating shafts. A driven gear is fixedly sleeved on each of the four sets of sleeves. The driven gear meshes with the driving gear.

[0007] Preferably, two sets of right-angled trapezoidal positioning blocks are fixedly connected symmetrically on both the left and right sides of the top of the base.

[0008] Preferably, the top of the base is symmetrically fixedly connected with two sets of support plates, and the transmission rod is rotatably mounted on the two sets of support plates.

[0009] Preferably, the bottom ends of all four sets of supports are fixedly connected with anti-slip rubber pads, and the thickness of the anti-slip rubber pads and supports is the same as the depth of the settling trough.

[0010] Preferably, an anti-slip handle sleeve is fixedly fitted on the outer wall of the handle.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When using it, when fixing the work platform, the operator can rotate the transmission rod by handwheel to rotate the four sets of worm gear shafts to the four corners of the base. Then, by holding the handle and rotating the threaded support column, the threaded support column pushes the support to move downward, so that the support can be supported with the ground. Thus, the four sets of supports are supported around the four corners of the base, which can effectively expand the support range of the work platform, make the support of the work platform more stable, and improve stability.

[0013] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope. Example

[0014] Please see Figures 1-4This utility model discloses a ship repair and construction operation platform, comprising a base 1, four sets of sleeves 4, and a transmission rod 13. Four sets of self-locking casters 2 are fixedly installed at the bottom of the base 1. A liftable and expandable ship repair and construction operation platform 3 is provided at the top of the base 1. The four sets of sleeves 4 are rotatably mounted on four sets of guide columns within the liftable and expandable ship repair and construction operation platform 3. The bottom ends of the sleeves 4 and the support arms 5 are in contact with the top of the base 1. Support arms 5 are integrally and fixedly connected to the outer walls of each of the four sets of sleeves 4. 5. A threaded support column 6 is screwed on the top of the threaded support column 6. A sleeve 7 is fixedly connected to the top of the threaded support column 6. Two sets of screw handles 8 are symmetrically fixedly connected to the sleeve 7. A support 9 is fixedly connected to the bottom of the threaded support column 6. A groove 10 is opened on the side of the bottom of the support arm 5 away from the sleeve 4. The groove 10 is directly above the support 9, and the depth of the groove 10 is slightly greater than the thickness of the support 9. Extension plates 11 are integrally connected to both ends of the base 1. Support plates 12 are fixedly connected to the top of both sets of extension plates 11. The transmission rod 13 is rotatably mounted on both ends. On the support plate 12, a handwheel 14 is fixedly connected to the right end of the transmission rod 13. Worm shaft sections 15 are integrally formed on both sides of the outer wall of the transmission rod 13. Four sets of rotating shafts 16 are symmetrically rotatably connected to the top of the base 1. Worm wheels 17 are fixedly connected to the top of each of the four sets of rotating shafts 16, and the four sets of worm wheels 17 mesh with the sides of two sets of worm shaft sections 15 respectively. A driving gear 18 is fixedly sleeved on each of the four sets of rotating shafts 16, and a driven gear 19 is fixedly sleeved on each of the four sets of sleeves 4. The driven gear 19 meshes with the driving gear 18. When in use, to fix the work platform, the operator can rotate the transmission rod 13 by turning the handwheel 14, which will rotate the four sets of worm shaft segments 15 to the four corners of the base 1. Then, by holding the handle 8, the operator can rotate the threaded support column 6, which will push the support 9 downward, so that the support 9 can be supported with the ground. This will allow the four sets of support 9 to be supported around the four corners of the base 1, which can effectively expand the support range of the work platform, make the support of the work platform more stable, and improve the stability.

[0015] Two sets of right-angled trapezoidal positioning blocks 23 are symmetrically fixed to the left and right sides of the top of the base 1. When the support arm 5 is rotated outward, the right-angled trapezoidal positioning blocks 23 can be used to position the support arm 5. During the rotation, when the outer side of the support arm 5 abuts against the inner inclined surface of the right-angled trapezoidal positioning block 23, the support arm 5 can no longer rotate, thus positioning the support arm 5. At this time, the support arm 5 moves to the corner of the base 1, so that the support arm 5 and the support 9 are fully extended to reach the maximum support range, which makes it easy to rotate the support arm 5 to the maximum extended position.

[0016] Two sets of support plates 20 are fixedly connected symmetrically to the top of the base 1. The transmission rod 13 is rotatably mounted on the two sets of support plates 20. By setting the support plates 20, the transmission rod 13 can be supported, so that the middle part of the transmission rod 13 will not sag, and the transmission rod 13 will be effectively prevented from bending.

[0017] The bottom of each of the four sets of supports 9 is fixedly connected with an anti-slip pad 21, and the thickness of the anti-slip pad 21 and the support 9 is the same as the depth of the sink 10. By setting the anti-slip pad 21, the support 9 can avoid slipping when supporting the ground, making the support more stable.

[0018] An anti-slip handle sleeve 22 is fixedly fitted on the outer wall of the handle 8; by setting the anti-slip handle sleeve 22, the hand is prevented from slipping when the handle 8 is gripped and the threaded support column 6 is rotated.

[0019] This utility model discloses a ship repair and construction operation platform. Its working principle is as follows: Initially, the support 9 and anti-slip pad 21 are in the settling tank 10, and the support arm 5 is folded up on the base 1. The outer edge of the support arm 5 is parallel to the front and rear ends of the base 1. After the operation platform is pushed to the appropriate position, it is fixed. During fixing, the transmission rod 13 is rotated by the handwheel 14. The transmission rod 13 drives the rotating shaft 16 to rotate through the meshing of the worm shaft section 15 and the worm wheel 17. The rotating shaft 16 drives the sleeve 4 to rotate outward through the meshing of the driving gear 18 and the driven gear 19. This, in turn, causes the sleeve 4 to drive the support arm 5 to rotate outward. The outer edge of the support arm 5 then abuts against the right-angled trapezoidal positioning block 2. When the inner slope is 3, the transmission rod 13 can no longer rotate. The meshing of the worm shaft section 15 and the worm wheel 17 has a self-locking effect, preventing the support arm 5 from rotating in the reverse direction. This fixes the support arm 5 in place. Then, by holding the handle 8, the threaded support column 6 is rotated, causing the threaded support column 6 to push the support 9 down until the support 9 is supported on the ground. The four sets of supports 9 are supported next to the corner of the base 1, thus supporting and fixing the work platform. When the work platform does not need to be fixed, the threaded support column 6 is rotated by the handle 8, causing the threaded support column 6 to lift the support 9 and put it into the sink 10. Then, the transmission rod 13 is rotated in the reverse direction by the handwheel 14, causing the support arm 5 to be retracted onto the base 1.

[0020] The ship repair and construction operation platform of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the beneficial effect can be implemented. The self-locking universal wheel 2 and the liftable and expandable ship repair and construction operation platform 3 in this utility model are both referenced from a ship repair and construction operation platform with patent publication number CN220410852U. They belong to the prior art that has been disclosed. The specific structure and working principle have been described in detail in the published patent. This application only references its function and does not make any changes to the structure. Therefore, it will not be described in detail here.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
