Description

Technical Field

[0001] The utility model relates to the technical field of interior decoration of construction projects, in particular to a lifting device for interior decoration of construction projects. Background Art

[0002] Interior decoration includes room design, renovation, furniture arrangement, and various minor decorative touches. It focuses on the interior of a building, encompassing both the design and construction phase and ongoing decoration after moving in. Furthermore, the concept of "light renovation, heavy decoration" should be gradually established. During renovation, lifting equipment is often required when lifting goods from the ground to the interior.

[0003] The portable hoist with patent number CN201012883Y is equipped with a power box as a base, and an assembly bracket part on the upper part; the main body of the assembly bracket part is a vertical pole, which is inserted into the hole of the power box base and placed on the floor near the window or balcony indoors, with the top against the ceiling and equipped with a torsion device. The vertical pole becomes a rotating arm, and heavy objects on the ground are lifted to the interior of a high-rise building through steel cables, pulleys, and hooks.

[0004] However, research has shown that existing single-column indoor hoists still have the following defects:

[0005] When the existing single-column indoor hoist is lifting goods, the sleeve will rotate due to the wind blowing on the goods. The rotation of the sleeve will cause the goods to swing more violently, which may cause the goods to fall and accidentally injure others. Therefore, the staff needs to hold the sleeve to prevent the sleeve from rotating when lifting the goods. However, holding the sleeve for a long time will increase the work intensity of the staff. At the same time, since the single-column indoor hoist relies on the friction between the top and the roof and the friction between the bottom and the ground to fix it, when the weight of the goods is too heavy, it may cause the single-column indoor hoist to fall off, and then cause the goods to fall. Therefore, it is necessary to optimize the lifting device for interior decoration of construction projects through technological innovation and design optimization. Utility Model Content

[0006] When an existing single-column indoor hoist is lifting goods, the sleeve will rotate due to the wind blowing on the goods. The rotation of the sleeve will cause the goods to swing more violently, which may cause the goods to fall and accidentally injure others. Therefore, the staff needs to grab the sleeve to prevent the sleeve from rotating when lifting the goods. However, holding the sleeve for a long time will increase the work intensity of the staff. At the same time, since the single-column indoor hoist is fixed by the friction between the top and the roof and the bottom and the ground, when the weight of the goods is too heavy, it may cause the single-column indoor hoist to fall off, and then cause the goods to fall. In order to solve the above problems, the embodiment of the present application provides a lifting device for interior decoration of construction projects, in which a limit column is driven upward by a spring, and the top of the limit column can be inserted into the limit hole to facilitate the limiting of the sleeve and the fixing ring to prevent the sleeve from rotating, thereby ensuring the stability of the goods when the goods are raised. The movable plate can be driven to move by rotating the screw rod, and the guide column is convenient for guiding the movable plate. The movable plate will press against the eaves to support the top of the lifting device body to prevent the lifting device body from falling off the wall, thereby improving the stability of the top of the lifting device body.

[0010] A sleeve, the sleeve being sleeved on the top of the lifting device body, and a fixing ring being fixed on the lifting device body at the bottom of the sleeve;

[0011] A limiting mechanism, located on the sleeve and the fixing ring, for limiting the sleeve and the fixing ring;

[0012] A rectangular block is fixed on the top of the lifting device body, and a reinforcement mechanism is provided on the rectangular block for reinforcing the lifting device body with the help of the eaves.

[0013] In one possible implementation, the limiting mechanism includes a lower fixed plate fixed on a fixing ring, two rectangular plates are fixed to the bottom of the lower fixed plate, a connecting plate is fixed to the bottom of the two rectangular plates, a limiting column passes through the connecting plate, the top of the limiting column passes through the lower fixed plate, a circular plate is fixed on the limiting column between the lower fixed plate and the connecting plate, and a spring is sleeved on the outside of the limiting column between the circular plate and the connecting plate. When the spring is in a compressed state, it will drive the limiting column to move upward through the circular plate.

[0014] In one possible implementation, an upper fixing plate is fixed on the sleeve, and a limiting hole is provided on the upper fixing plate. The top end of the limiting column can be inserted into the limiting hole to facilitate limiting the sleeve and the fixing ring, prevent the sleeve from rotating, and ensure the stability of the goods when the goods are raised.

The protrusion can enter the slot, and the limiting column is rotated. The limiting column drives the circular plate to rotate, and the circular plate will drive the protrusion to rotate. The protrusion will enter the inside of Cao Yu, thereby limiting the circular plate and then limiting the limiting column, preventing the limiting column from being inserted into the limiting hole in the upper fixed plate, thereby facilitating the free rotation of the sleeve.

[0017] In one possible implementation, the reinforcement mechanism includes a screw rod and a guide column passing through a rectangular block, a movable plate is provided at the same end of the screw rod and the guide column, and a rotating block is fixed at the other end of the screw rod, and the rotating block is provided with anti-slip grooves.

[0019] In one possible implementation, when the protrusion is located inside the slot, the top end of the limit column is located between the upper fixed plate and the lower fixed plate. At this time, the limit column does not control the upper fixed plate, and the sleeve can rotate freely, making it easier to rotate the goods into the room.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solution of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] This embodiment introduces a specific structure of a lifting device for interior decoration of construction engineering. Figure 1-Figure 4 As shown, a lifting device for interior decoration of construction engineering comprises:

[0030] The hoisting device body 1 is a single-column indoor hoist;

[0031] The sleeve 3 is sleeved on the top of the lifting device body 1, and a fixing ring 2 is fixed on the lifting device body 1 at the bottom of the sleeve 3;

[0032] The limiting mechanism is located on the sleeve 3 and the fixing ring 2 and is used to limit the sleeve 3 and the fixing ring 2;

[0033] The rectangular block 4 is fixed on the top of the lifting device body 1. The rectangular block 4 is provided with a reinforcement mechanism that can reinforce the lifting device body 1 with the help of the eaves.

[0034] When the single-column indoor hoist currently on the market is lifting goods, the sleeve 3 will rotate due to the wind blowing on the goods. The rotation of the sleeve 3 will cause the goods to swing more violently, which may cause the goods to fall and accidentally injure others. Therefore, the staff is required to hold the sleeve 3 to prevent the sleeve 3 from rotating when lifting the goods. However, holding the sleeve 3 for a long time will increase the work intensity of the staff.

[0035] The limiting mechanism includes a lower fixed plate 9 fixed on the fixing ring 2, two rectangular plates 10 are fixed at the bottom of the lower fixed plate 9, a connecting plate 12 is fixed at the bottom of the two rectangular plates 10, a limiting column 13 passes through the connecting plate 12, the top of the limiting column 13 passes through the lower fixed plate 9, a circular plate 16 is fixed on the limiting column 13 between the lower fixed plate 9 and the connecting plate 12, and a spring 19 is sleeved on the outside of the limiting column 13 between the circular plate 16 and the connecting plate 12. When the spring 19 is in a compressed state, it will drive the limiting column 13 to move upward through the circular plate 16.

[0036] An upper fixing plate 15 is fixed on the sleeve 3, and a limiting hole 14 is provided on the upper fixing plate 15. The top end of the limiting column 13 can be inserted into the limiting hole 14, which is convenient for limiting the sleeve 3 and the fixing ring 2, preventing the sleeve 3 from rotating, and ensuring the stability of the goods when the goods are raised.

[0037] The limiting column 13 can slide on the connecting plate 12 and the lower fixed plate 9. A pulling block 11 is fixed to the bottom end of the limiting column 13. The pulling block 11 is provided with anti-slip grooves to facilitate pulling the limiting column 13 through the pulling block 11.

[0038] A protrusion 17 is fixed on the circular plate 16, and a notch 18 is provided on the facing surfaces of the two rectangular plates 10. The protrusion 17 can enter the notch 18, and the limiting column 13 is rotated. The limiting column 13 drives the circular plate 16 to rotate, and the circular plate 16 will drive the protrusion 17 to rotate. The protrusion 17 will enter the inside of Cao Yu, thereby limiting the circular plate 16, and then limiting the limiting column 13, preventing the limiting column 13 from being inserted into the limiting hole 14 in the upper fixed plate 15, so as to facilitate the free rotation of the sleeve 3.

[0039] When the protrusion 17 is located inside the notch 18, the top end of the limiting column 13 is located between the upper fixing plate 15 and the lower fixing plate 9. At this time, the limiting column 13 does not control the upper fixing plate 15, and the sleeve 3 can rotate freely, making it easy to rotate the goods into the room.

[0040] Since the single-column indoor hoist relies on the friction between the top and the roof and the bottom and the ground to fix it, when the weight of the goods is too heavy, it may cause the single-column indoor hoist to fall off, and then cause the goods to fall.

[0041] The reinforcement mechanism includes a screw rod 7 and a guide column 6 passing through the rectangular block 4. A movable plate 5 is provided at the same end of the screw rod 7 and the guide column 6. A rotating block 8 is fixed to the other end of the screw rod 7. The rotating block 8 is provided with anti-slip grooves. The movable plate 5 can be driven to move by rotating the screw rod 7, and the guide column 6 facilitates guiding the movable plate 5.

[0042] The screw rod 7 is threadedly connected to the rectangular block 4, the guide column 6 is slidingly connected to the rectangular block 4, the screw rod 7 is rotatably connected to the movable plate 5, and the guide column 6 is fixedly connected to the movable plate 5, so that the screw rod 7 drives the movable plate 5 to move, so that the movable plate 5 rests against the eaves, supports the top of the lifting device body 1, and prevents the lifting device body 1 from falling off the wall.

[0043] The staff first installs the lifting device body 1 and rotates the screw rod 7. The screw rod 7 drives the movable plate 5 to move. The movable plate 5 will rest against the eaves. At this time, the limit column 13 is rotated. The limit column 13 drives the circular plate 16 to rotate. The circular plate 16 drives the protrusion 17 to move out of the slot 18. At this time, under the action of the spring 19, the limit column 13 will be inserted into the limit hole 14 inside the upper fixed plate 15. At this time, the lifting device body 1 is controlled to lift the goods. When the goods are lifted to an appropriate height, the lifting device body 1 is closed, the limit column 13 is pulled down and rotated. The limit column 13 drives the circular plate 16 to rotate, and the circular plate 16 will drive the protrusion 17 to rotate, and the protrusion 17 will enter the inside of Cao Yu, thereby limiting the circular plate 16, and then limiting the limit column 13, preventing the limit column 13 from being inserted into the limit hole 14 in the upper fixed plate 15, so that the sleeve 3 can rotate freely and move the goods indoors.

[0044] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
