Description

Technical Field

[0001] This utility model relates to the field of material lifting technology, specifically a material lifting device for building decoration. Background Technology

[0002] Building decoration refers to activities such as chiseling walls, floors, moving windows, demolishing or altering load-bearing or non-load-bearing structures, adding room partition structures, improving the appearance of a house, and decorating the interior layout. In the early stages of building decoration construction, building materials often need to be moved and installed manually, which not only increases the labor intensity of workers, but also results in low work efficiency and certain safety hazards.

[0003] Utility model patent CN219567448U discloses a material lifting device for building decoration, comprising: a main lifting unit, which includes a support base and a support frame fixedly installed on one end of the upper side wall of the support base; the upper inner wall of the support frame and the upper side wall of the support base are rotatably connected to two sets of symmetrically positioned threaded columns, both of which are arranged to penetrate the support frame upwards; and a material clamping unit, which includes a lifting plate fixedly connected to a connecting plate and a power box fixedly installed at the center of the lower side wall of the lifting plate; the inner walls of both ends of the power box are rotatably connected to a bidirectional screw rod, and a second motor fixedly installed at one end of the power box and fixedly connected to one end of the bidirectional screw rod; and symmetrically positioned moving blocks are threadedly connected to the bidirectional screw rod.

[0004] In the above technical solution, materials are stacked on the lifting plate, and the output shaft of the second motor drives the bidirectional lead screw to rotate. The moving block connected to it then drives the clamping arm to clamp the decorative material from both sides. The piston rod of the hydraulic cylinder is extended, and the pressure plate fixedly connected to it presses and holds the decorative material from above, which can effectively limit the material on the lifting plate in both horizontal and vertical directions. However, after the material is stacked, when the material needs to be conveyed to different positions on the same horizontal plane, the horizontal conveying position cannot be flexibly adjusted to facilitate the user's handling. In addition, the material lifting device is not convenient for coordinating material conveying in multiple directions to reduce the impact of overall handling and movement. Utility Model Content

[0005] The purpose of this utility model is to provide a material lifting device for building decoration, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A material lifting device for building decoration includes a fixed base and a column slidably connected to the top of the fixed base. The column is equipped with a material lifting and conveying component. A trapezoidal groove is formed on the upper surface of the fixed base. A hydraulic cylinder is provided at the right end of the fixed base. A counterweight base is provided below the fixed base. A rotating column is provided at the bottom of the column. A rotating seat is provided below the rotating column. A trapezoidal block is provided at the bottom of the rotating seat corresponding to the trapezoidal groove. The piston rod of the hydraulic cylinder extends to the inner wall of the trapezoidal groove and is connected to the side wall of the trapezoidal block. A rotating groove is formed at the top of the rotating seat corresponding to the rotating column. A T-shaped groove is formed in the middle of the top of the column. Limiting grooves are formed on both sides of the T-shaped groove at the top of the column. A top plate is provided above the top of the column. A motor is provided on the upper surface of the top plate. The output shaft of the motor passes through the top plate and extends into the T-shaped groove. A screw is coaxially connected to the end of the output shaft.

[0008] The transport assembly includes a lifting plate and a pallet connected to the upper surface of the lifting plate. A T-shaped block is provided on one side of the lifting plate at a position corresponding to the T-slot. A second screw hole is provided on the T-block at a position corresponding to the screw. A reinforcing plate is also provided on one side of the lifting plate. Limiting posts are provided on the reinforcing plate at positions corresponding to the limiting slots.

[0009] Furthermore, the tray has symmetrical slots near the port, a baffle is provided between the two slots, and a handle groove is provided on the baffle near the top.

[0010] In this invention, the width of the outer wall of the baffle is matched with the width of the inner wall of the slot, and the handle slot provides a point of leverage, making it convenient for the baffle to be inserted, installed, or removed. The baffle installation protects the materials being transported in the pallet, reducing the risk of them rolling off the pallet during lifting or lowering and causing injury to those below.

[0011] Specifically, the T-shaped block and the lifting plate are integrally formed, the width of the outer wall of the T-shaped block is adapted to the width of the inner wall of the T-shaped groove, the screw is threadedly connected to the second screw hole, the limiting post and the reinforcing plate are integrally formed, and the reinforcing plate is welded and fixed to the lifting plate, and the limiting post is slidably inserted into the limiting groove.

[0012] In this invention, the T-shaped block and the T-shaped slot are inserted and matched to realize the lifting plate moving up and down in the column. The reinforcing plate is equipped with a limiting post and is inserted and matched with the corresponding limiting slot to increase the stability of the lifting plate moving up and down.

[0013] It should be noted that a locking block is provided at the bottom of the top plate corresponding to the T-slot. The locking block is inserted into the top of the column. The motor is fixedly connected to the top plate by screws. The top plate is fixedly connected to the column by screws. The output shaft of the motor is welded and fixed to the screw rod. The bottom of the screw rod is inserted into the bottom of the column and rotated.

[0014] In this invention, a locking block is fitted on the top plate to enable quick and easy installation of the top plate and the column. A control switch is fitted on the outer wall of the motor and is electrically connected to an external power source via a wire. When the control switch is activated, the output shaft of the motor rotates. When the output shaft rotates in the forward direction, it drives the screw to rotate in the forward direction, thereby lifting the lifting plate. When the output shaft rotates in the reverse direction, it drives the screw to rotate in the reverse direction, thereby lowering the lifting plate. This ensures the stability of material lifting or lowering. Furthermore, the bottom of the screw is inserted into and rotates with the bottom of the column to ensure the stability of the screw rotation.

[0015] Furthermore, the top of the rotating column is welded and fixed to the bottom of the column, and a handle is provided on the outer wall of the column near the bottom. The outer diameter of the rotating column is adapted to the inner diameter of the rotating groove. A first screw hole communicating with the inside of the rotating groove is opened on the outer wall of the rotating seat, and a fixing bolt is provided in the first screw hole.

[0016] In this invention, the handle provides a point of force, which pushes the handle to achieve rotational engagement between the rotating column with the upright column and the rotating groove on the rotating seat. The fixing bolt is threadedly connected to the first screw hole, and the end of the fixing bolt is closely fitted to the rotating column. Under the action of friction, the fixing bolt fixes the position of the rotating column after rotation, thereby achieving adjustment and fixation of the rotation direction of the lifting plate on the horizontal plane.

[0017] Secondly, the bottom of the top rotating seat of the trapezoidal block is welded and fixed, and the width of the outer wall of the trapezoidal block is adapted to the width of the inner wall of the trapezoidal groove.

[0018] In this invention, the trapezoidal block and the trapezoidal groove slide together, enabling the column with the transport component to move laterally on the horizontal plane, thus coordinating the material transport at the same horizontal position and facilitating the user to obtain the materials on the pallet.

[0019] It is worth noting that the hydraulic cylinder is fixedly connected to the fixed base by screws, and the end of the piston rod of the hydraulic cylinder is fixedly connected to the side wall of the trapezoidal block by bolts.

[0020] In this invention, the working principle of the hydraulic cylinder is to convert hydraulic energy into mechanical energy. The hydraulic cylinder includes components such as cylinder barrel, piston, piston rod, and seals. The cylinder barrel, cylinder head, piston, and other components together form a closed oil chamber. The hydraulic cylinder controls the movement of the piston by compressing the oil in the low-pressure chamber of the cylinder barrel and slowly releasing it through the throttle orifice. When hydraulic oil enters the cylinder barrel from one side, it pushes the piston to move to the other side, and then outputs mechanical energy through the piston rod, thereby pushing the trapezoidal block to move horizontally in the trapezoidal groove.

[0021] Furthermore, the bottom of the fixed base is fixedly connected to the counterweight base by bolts, the width of the outer wall of the counterweight base is greater than the width of the outer wall of the fixed base, and several support feet are provided on the lower surface of the counterweight base near the four edges.

[0022] In this invention, the counterweight base increases the stability of the fixed base and the bottom of the column in contact with the ground, lowers the overall center of gravity, and reduces the impact of top-heavy and overall tipping when transporting goods in the pallet. The tops of multiple support legs are welded and fixed to the bottom of the fixed base to support the entire device.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. This utility model lowers the overall center of gravity by setting a fixed seat for the counterweight base. The rotating seat with the column slides with the trapezoidal block and the trapezoidal groove on the fixed seat. The hydraulic cylinder provides the power for the horizontal movement of the rotating seat. A motor with a screw is installed on the top of the column. The screw rotates in the T-slot and is threadedly connected to the second screw hole on the lifting plate. The rotation of the screw drives the lifting plate to move up and down in the column. The top of the lifting plate is fitted with a tray, and with the help of a baffle, the material stored in the tray is intercepted and protected to prevent the material from falling during lifting or lowering.

[0025] 2. This utility model sets a fixing bolt that is threadedly connected to the first screw hole, and the end of the fixing bolt is in contact with the rotating column. Under the action of friction, the position of the rotating column is fixed, thereby realizing the rotation position of the column on the horizontal plane. This enables the pallet to transport materials in multiple directions. With the reinforcement plate with the limit column, the stability of the lifting plate and the column sliding up and down is increased. Attached Figure Description

The piston rod end of the hydraulic cylinder 2 is fixedly connected to the side wall of the trapezoidal block 31 by bolts.

[0041] In this utility model, the working principle of the hydraulic cylinder 2 is to convert hydraulic energy into mechanical energy. The hydraulic cylinder 2 includes components such as cylinder barrel, piston, piston rod and seals. The cylinder barrel, cylinder head, piston and other components together form a closed oil chamber. The hydraulic cylinder 2 compresses the oil in the low-pressure chamber of the cylinder barrel and slowly releases it through the throttle orifice, thereby controlling the movement of the piston. When the hydraulic oil enters the cylinder barrel from one side, it pushes the piston to move to the other side, and then outputs mechanical energy through the piston rod, thereby pushing the trapezoidal block 31 to move horizontally in the trapezoidal groove 10.

[0042] Furthermore, a counterweight base 11 is provided below the fixed base 1. The bottom of the fixed base 1 and the counterweight base 11 are fixedly connected by bolts.

The tops of multiple support legs 110 are welded and fixed to the bottom of the fixed seat 1 to support the entire device.

[0044] Specifically, a rotating column 40 is provided at the bottom of the column 4, and a rotating seat 3 is provided below the rotating column 40. A trapezoidal block 31 is provided at the bottom of the rotating seat 3 corresponding to the trapezoidal groove 10. The top of the trapezoidal block 31 is welded and fixed to the bottom of the rotating seat 3. The width of the outer wall of the trapezoidal block 31 is adapted to the width of the inner wall of the trapezoidal groove 10.

[0045] In this utility model, the trapezoidal block 31 and the trapezoidal groove 10 slide together, so that the column 4 with the transport component 5 can move laterally on the horizontal plane, and material transport can be carried out at the same horizontal position, making it convenient for users to obtain the materials on the pallet 51.

[0046] It should be noted that the piston rod of the hydraulic cylinder 2 extends to the inner wall of the trapezoidal groove 10 and is connected to the side wall of the trapezoidal block 31. A rotating groove 30 is provided at the top of the rotating seat 3 corresponding to the rotating column 40. The top of the rotating column 40 is welded and fixed to the bottom of the column 4. A handle 41 is also provided on the outer wall of the column 4 near the bottom. The outer diameter of the rotating column 40 is adapted to the inner diameter of the rotating groove 30. A first screw hole 32 communicating with the inside of the rotating groove 30 is provided on the outer wall of the rotating seat 3. A fixing bolt 320 is provided in the first screw hole 32.

[0047] In this utility model, the handle 41 provides a point of force to push the handle 41 to achieve rotational engagement between the rotating column 40 with the column 4 and the rotating groove 30 on the rotating seat 3. The fixing bolt 320 is threadedly connected to the first screw hole 32. The end of the fixing bolt 320 is closely attached to the rotating column 40, and under the action of friction, the fixing bolt 320 fixes the position of the rotating column 40 after rotation, thereby realizing the adjustment and fixation of the rotation direction of the lifting plate 50 on the horizontal plane.

[0048] Furthermore, a T-slot 42 is provided at the middle of the top of the column 4, and limit slots 43 are provided on both sides of the top of the column 4 at the T-slot 42. A top plate 44 is provided above the top of the column 4, and a motor 45 is provided on the upper surface of the top plate 44. The output shaft of the motor 45 passes through the top plate 44 and extends into the T-slot 42, and a screw 450 is coaxially connected to the end of the output shaft. A locking block is provided at the bottom of the top plate 44 corresponding to the T-slot 42. The locking block is inserted into the top of the column 4. The motor 45 is fixedly connected to the top plate 44 by screws, and the top plate 44 is fixedly connected to the column 4 by screws. The output shaft of the motor 45 is welded and fixed to the screw 450, and the bottom of the screw 450 is inserted into the bottom of the column 4 and rotated.

[0049] In this invention, a locking block is fitted on the top plate 44 to enable quick and easy installation of the top plate 44 and the column 4. A control switch is fitted on the outer wall of the motor 45, and the control switch is electrically connected to an external power source via a wire. When the control switch is activated, the output shaft of the motor 45 rotates. When the output shaft rotates in the forward direction, it drives the screw 450 to rotate in the forward direction, thereby lifting the lifting plate 50. When the output shaft rotates in the reverse direction, it drives the screw 450 to rotate in the reverse direction, thereby lowering the lifting plate 50. This ensures the stability of material lifting or lowering. The bottom of the screw 450 is inserted into and rotates with the bottom of the column 4, ensuring the stability of the screw 450's rotation.

[0050] It is worth noting that the transport component 5 includes a lifting plate 50 and a tray 51 connected to the upper surface of the lifting plate 50. A T-shaped block 500 is provided on one side of the lifting plate 50 at a position corresponding to the T-slot 42. A second screw hole 501 is provided on the T-shaped block 500 at a position corresponding to the screw 450. The T-shaped block 500 and the lifting plate 50 are integrally formed. The width of the outer wall of the T-shaped block 500 is adapted to the width of the inner wall of the T-slot 42. The screw 450 is threadedly connected to the second screw hole 501. The limiting post 503 and the reinforcing plate 502 are integrally formed. The reinforcing plate 502 is welded and fixed to the lifting plate 50. The limiting post 503 is slidably inserted into the limiting slot 43.

[0051] In this utility model, the T-shaped block 500 is inserted into the T-shaped groove 42 to enable the lifting plate 50 to move up and down in the column 4. The reinforcing plate 502 is fitted with the limiting post 503 and is inserted into the corresponding limiting groove 43 to increase the stability of the lifting plate 50 moving up and down.

[0052] Furthermore, a reinforcing plate 502 is provided on one side of the lifting plate 50, and a limiting post 503 is provided on the reinforcing plate 502 at the corresponding position of the limiting groove 43.

[0053] Secondly, the tray 51 has symmetrical slots 510 near the port, and a baffle 511 is provided between the two slots 510. A handle groove 512 is provided on the baffle 511 near the top.

[0054] In this utility model, the width of the outer wall of the baffle 511 is adapted to the width of the inner wall of the slot 510, and the handle slot 512 provides a force point to facilitate the insertion and installation or removal of the baffle 511. The installation of the baffle 511 protects the materials transported in the pallet 51 and reduces the risk of materials rolling off the pallet 51 during lifting or lowering, thus preventing damage to those below.

[0055] In this embodiment, when the building decoration material lifting device is in use, firstly, the counterweight base 11 with support feet 110 is combined and fixed with the fixed seat 1 with trapezoidal groove 10, and the hydraulic cylinder 2 is fixed on the side wall of the fixed seat 1. The rotating seat 3 with rotating groove 30 is slidably inserted into the trapezoidal groove 10 through the trapezoidal block 31. The piston rod of the hydraulic cylinder 2 is combined and fixed with the trapezoidal block 31. Then, the column 4 with motor 45 is rotatably connected to the rotating groove 30 through the rotating column 40. The lifting plate 50 with tray 51 is inserted into the T-shaped groove 42 through the T-shaped block 500.

[0056] The entire device is moved to the location where the decoration materials need to be transported. When the lifting plate 50 is at the bottom of the column 4, the materials are placed in the tray 51 in sequence, and the baffle 511 is inserted into the slot 510 to protect the stored materials. Then the motor 45 is connected to the external power supply and the control switch is started, so that the output shaft of the motor 45 can rotate. When the output shaft rotates in the forward direction, it drives the screw 450 to rotate in the forward direction, thereby realizing the lifting plate 50 to move and the materials in the tray 51 are lifted to the height where the materials need to be picked up.

[0057] When the corresponding height is adjusted, and the material needs to be moved on the horizontal plane, the hydraulic cylinder 2 compresses the oil in the low-pressure chamber of the cylinder and slowly releases it through the throttle orifice to control the movement of the piston. When the hydraulic oil enters the cylinder from one side, it pushes the piston to move to the other side, and then outputs mechanical energy through the piston rod, which in turn pushes the trapezoidal block 31 to move horizontally in the trapezoidal groove 10, thus realizing the movement on the horizontal plane.

[0058] When the corresponding height is adjusted, and materials need to be supplied in different directions, the column 4 rotates on the rotating seat 3 through the rotating column 40 with the help of the handle 41. After rotation, the fixing bolt 320 is threadedly connected to the first screw hole 32. The end of the fixing bolt 320 is attached to the outer wall of the rotating column 40 and the position of the rotating column 40 is fixed under the action of friction, thereby realizing the material supply component 5 to rotate in different directions on the horizontal plane.

[0059] When materials at a height need to be lowered to the ground, the corresponding materials are placed in the tray 51, the control switch is activated, the output shaft of the motor 45 rotates in the reverse direction, driving the screw 450 to rotate in the reverse direction, thereby realizing the lowering and movement of the lifting plate 50, and thus realizing the lowering and lowering of the materials.
