Description

Technical Field

[0001] This invention relates to the field of transportation technology, and more specifically to a building material conveying device. Background Technology

[0002] During the construction of high-rise buildings, the transportation of building materials mainly relies on tower cranes. When transporting building materials, they need to be tied up first and then hoisted to the designated location. After the main frame of the high-rise building is completed, construction workers can also use freight elevators to transport building materials at the same time.

[0003] After the main framework of a high-rise building is completed, building materials can be transported using tower cranes to hoist them to a cargo transfer platform, and then moved to designated floors via freight elevators or manually. However, freight elevators only have one car, and when multiple construction teams are working simultaneously, the demand often exceeds the supply. Furthermore, multiple construction teams often work on different floors simultaneously; for example, teams on higher floors might be setting up formwork or building walls, while teams on lower floors might be laying pipes or painting walls. This results in different material requirements for teams on different floors. When using freight elevators, one team must complete the cargo transfer before another can use it. Therefore, after building materials are transferred to the building framework transfer platform by tower crane, workers often need to use other means to move them to other floors where materials are needed. This results in low material transfer efficiency and significant physical exertion for workers, requiring improvement.

[0004] Based on the above background, the inventors designed a building material conveying device to solve at least one of the above problems, and hereby file this application. Summary of the Invention

[0005] The purpose of this application is to provide a building material conveying device that can solve the current problem that after the tower crane lifts the building materials to the transfer platform, the building materials can only be transported by queuing for the freight elevator or by manual handling.

[0006] To address the above problems, this application provides the following technical solution:

[0007] This application provides a building material conveying device, including a first lifting frame and a second lifting frame that can be raised and lowered vertically, and a plurality of lifting trays fixed on the first lifting frame and the second lifting frame;

[0008] The first and second lifting frames are arranged side by side in parallel, and the single lifting height of both the first and second lifting frames is equal to the height of a single floor.

[0009] Several lifting trays are evenly distributed on one side of the first lifting frame and the second lifting frame, and the vertical spacing between adjacent lifting trays is the same as the height of a single floor.

[0010] It also includes at least one hopper assembly for placing on the lifting pallet and transporting materials, and at least one set of shifting assemblies located between the first lifting frame and the second lifting frame for driving the hopper assembly to rotate and shift.

[0011] The hopper assembly is sleeved on the reversing assembly and slidably connected to it vertically;

[0012] When the first and second lifting frames are in the raised or lowered state, the orthographic projection of the hopper assembly only overlaps with the lifting tray on the first or second lifting frame.

[0013] Optionally, the hopper assembly includes a hopper tray and a hopper body, as well as a locking assembly;

[0014] The hopper body is mounted on the hopper tray and slidably connected thereto, with the two ends of the locking assembly connected to the hopper tray and the hopper body, respectively.

[0015] The hopper tray is provided with a lifting through hole whose shape is adapted to the shifting component. The hopper tray is fitted onto the shifting component through the lifting through hole and is slidably connected to it.

[0016] Optionally, the hopper assembly further includes a straight slide rail that extends radially along the switching assembly.

[0017] Optionally, the transposition assembly includes a drive motor and a vertically arranged transposition rod;

[0018] The shift rod is connected to the output shaft of the drive motor, and the hopper assembly is mounted on the shift rod;

[0019] The lifting tray has a notch, and the shifting rod is located inside the notch.

[0020] Optionally, the cross-sectional shape of the transposition rod is any one of ellipse, oval, or polygon with edges.

[0021] Optionally, the lifting tray is also provided with an arc-shaped transposition rail;

[0022] The orthographic projections of the centers of the arcs on the first and second lifting frames where the transposition rails are located coincide.

[0023] The hopper assembly is rotatably connected to the lifting tray via a shifting arc rail.

[0024] Optionally, the shape of the transposition arc track is semi-circular;

[0025] When the lifting trays on the first and second lifting frames are at the same height, the two semi-circular interchangeable arc rails can form a circular track.

[0026] Optionally, it also includes a lifting drive assembly for driving the first and second lifting frames to move vertically;

[0027] The lifting drive assembly includes a lifting cylinder, a lifting piston, and a lifting drive rod. The lifting piston is located inside the lifting cylinder, and the lifting drive rod is vertically arranged with its bottom end fixedly connected to the lifting piston and its top end extending out of the lifting cylinder.

[0028] The bottoms of the first and second lifting frames are fixed to the top of the lifting drive rod.

[0029] Optionally, it also includes several partitioned platforms with the same height as the transfer platform;

[0030] The first and second lifting frames are installed through the partition platform and slidably connected to it;

[0031] The transposition component is set throughout the partition platform and can rotate freely, or a set of transposition components is set on each partition platform.

[0032] Optionally, the first lifting frame includes at least two vertically arranged first support rods;

[0033] The second lifting frame includes at least two vertically arranged second support rods;

[0034] Several lifting trays are fixed to the first lifting rod and the second lifting rod.

[0035] The beneficial effects of this invention are:

[0036] This application, by setting up a first lifting frame, a second lifting frame, a switching component, a hopper component, and a lifting pallet that work together, allows materials to be transported layer by layer, either upwards or downwards, after being placed in the hopper component, until the materials are transported to the designated floor. The core of this application lies in the ability to set up two or more hopper components. With the coordinated operation of these components, synchronous material feeding can be achieved. That is, while some hopper components continuously ascend to deliver materials, others continuously descend to deliver materials. When multiple construction teams simultaneously require different building materials, the material transport needs of multiple floors can be solved simultaneously, effectively addressing the problem of traditional building material transport methods that require queuing for freight elevators or relying on manual handling.

[0049] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0051] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "have," "install," "connect," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0053] like Figures 1 to 10 As shown, this embodiment provides a building material conveying device, including a first lifting frame 1 and a second lifting frame 2 that can be lifted vertically, and a plurality of lifting trays 3 fixed on the first lifting frame 1 and the second lifting frame 2;

[0054] The first lifting frame 1 and the second lifting frame 2 are arranged side by side in parallel, and the single lifting height of the first lifting frame 1 and the second lifting frame 2 is the same as the height of a single floor.

[0055] Several lifting trays 3 are evenly distributed on one side opposite to the first lifting frame 1 and the second lifting frame 2, and the vertical spacing between adjacent lifting trays 3 is the same as the height of a single floor.

[0056] It also includes at least one hopper assembly 4 for placing on the lifting pallet 3 and transporting materials, and at least one set of shifting components 5 located between the first lifting frame 1 and the second lifting frame 2 for driving the hopper assembly 4 to rotate and shift.

[0057] The hopper assembly 4 is mounted on the reversing assembly and is slidably connected to it vertically;

[0058] When the first lifting frame 1 and the second lifting frame 2 are in the lifting or lowering state, the orthographic projection of the hopper assembly 4 only overlaps with the lifting tray 3 on the first lifting frame 1 or the second lifting frame 2.

[0059] In this embodiment, when two construction teams have a need to transport building materials, the construction team at the lower position requests to transport the lower building materials upwards, while the construction team at the higher position requests to transport the upper building materials downwards. Figures 1 to 10 To illustrate, in the initial state, the two hopper assemblies 4 are placed on the lifting trays 3 of the first lifting frame 1 and the second lifting frame 2, respectively, as shown in the example below. Figure 1 As shown, after the material is placed onto the hopper assemblies 4 of the two lifting pallets 3, the lifting drive assembly 6 corresponding to the first lifting frame 1 is activated, causing the first lifting frame 1 to move upward one floor. The hopper assemblies 4 on the lifting pallet 3 of the first lifting frame 1 can move upward along with the lifting pallet 3 on the first lifting frame 1, while the hopper assemblies 4 on the lifting pallet 3 of the second lifting frame 2 remain in their original positions. The state at this time is as follows. Figure 4 As shown, the switching component 5 then drives the hopper component 4 to rotate 180°, causing both hopper components 4 to rotate 180° as well. The positions of the two hopper components 4 after the position change are as follows. Figure 5 As shown, subsequently, the first lifting frame 1 resets, and the hopper assembly 4 on the lifting tray 3 of the first lifting frame 1 descends synchronously by one floor height, while the height of the hopper assembly 4 on the lifting tray 3 of the second lifting frame 2 remains unchanged. The state at this time is as follows: Figure 7 As shown, through the rising action of the first lifting frame 1, the 180° rotation of the switching component 5, and the resetting action of the first lifting frame 1, the two hopper components 4 can respectively climb up one floor and descend one floor. At this time, if the building materials have not yet reached the corresponding floor, according to... Figure 8 As for Figure 10 As shown, by performing the rising action of the second lifting frame 2, the rotation action of the switching component 5 by 180°, and the reset action of the second lifting frame 2, the two hopper components 4 can be raised to one floor again.

[0060] Therefore, this embodiment, by setting up a first lifting frame 1, a second lifting frame 2, a switching component 5, a hopper component 4, and a lifting tray 3 that cooperate with each other, allows materials to be transported layer by layer after being placed in the hopper component 4, either by raising or lowering the floor until the material is transported to the designated floor. The core of this application is that it can set up two or more hopper components 4, and with the cooperation of the above components, synchronous material feeding can be achieved. That is, while some hopper components 4 are continuously raising the floor to feed materials, some hopper components 4 are continuously lowering the floor to feed materials. When multiple construction teams need different building materials at the same time, the material transportation needs of multiple floors can be solved simultaneously, thereby effectively solving the problem that traditional building material transportation can only queue for freight elevators or rely on manual handling.

[0061] In this embodiment, as Figure 2 and Figure 3As shown, the hopper assembly 4 includes a hopper tray 41, a hopper body 42, and a locking assembly 43;

[0062] The hopper body 42 is mounted on the hopper tray 41 and slidably connected thereto, and the two ends of the locking assembly 43 are respectively connected to the hopper tray 41 and the hopper body 42;

[0063] The hopper tray 41 is provided with a lifting through hole 411 whose shape is adapted to the shifting component 5. The hopper tray 41 is fitted onto the shifting component 5 through the lifting through hole 411 and is slidably connected to it.

[0064] The hopper assembly 4, by setting up a hopper tray 41, a hopper body 42, and a locking assembly 43, ensures that the hopper assembly 4 will not detach from the lifting tray 3 during the material conveying process. After the material is transported to the designated location, the locking assembly 43 is opened, and the hopper body 42 is pulled out from the hopper tray 41 to obtain building materials or to place building materials onto the hopper tray 41.

[0065] The locking assembly 43 in this embodiment is an existing mechanical component, which will not be described in detail here.

[0066] In this embodiment, the hopper body 42 is also provided with a handle on the side away from the switching component 5, which facilitates the pulling of the hopper body 42.

[0067] In this embodiment, the hopper assembly 4 also includes a straight slide rail 44, which extends radially along the shifting assembly 5. By setting the straight slide rail 44, the frictional resistance of the hopper body 42 being pulled out from the hopper tray 41 can be reduced, making it easier for construction personnel to operate.

[0068] In this embodiment, the transposition component 5 includes a drive motor 51 and a vertically arranged transposition rod 52;

[0069] The shift rod 52 is connected to the output shaft of the drive motor 51, and the hopper assembly 4 is mounted on the shift rod 52.

[0070] The lifting tray 3 is provided with a notch 32, and the shifting rod 52 is located in the notch 32 to avoid interference between the shifting rod 52 and the lifting tray 3 when rotating.

[0071] In this embodiment, the notch 32 is semi-circular in shape. Since the notches 32 of the two lifting trays 3 of equal height are arranged opposite each other, the two notches 32 can form a circular through hole, and the shifting rod 52 is located in the through hole formed by the two notches 32.

[0072] In this embodiment, the drive motor 51 and the shift rod 52 are coaxially fixedly connected by a coupling. In some embodiments, when the shift rod 52 is driven to rotate by the drive motor 51, it can also be driven by a gear transmission pair, which will not be described in detail here.

[0073] In this embodiment, the drive motor 51 is a servo motor or a stepper motor, and the rotation amplitude is 90° each time.

[0074] In this embodiment, as Figure 2 and Figure 3 As shown, the cross-sectional shape of the shift rod 52 is elliptical. In some embodiments, the cross-sectional shape of the shift rod 52 can also be oval or polygonal with edges, such as square, regular hexagon, etc. Of course, it can also be D-shaped or have a spline groove or other structure that restricts the free rotation of the shift rod 52 and the hopper assembly 4. Further examples will not be given here.

[0075] In this embodiment, the lifting tray 3 is also provided with an arc-shaped transposition rail 31;

[0076] The center of the arc on the first lifting frame 1 and the second lifting frame 2 coincides in the orthographic projection of the arc.

[0077] The hopper assembly 4 is rotatably connected to the lifting tray 3 via the shifting arc rail 31.

[0078] By setting an arc-shaped transposition rail 31, the resistance of the hopper assembly 4 when rotating and transposing on the lifting tray 3 can be reduced.

[0079] In this embodiment, as Figure 2 and Figure 3 As shown, the transposition arc track 31 is semi-circular in shape;

[0080] When the lifting trays 3 on the first lifting frame 1 and the second lifting frame 2 are at the same height, the two semi-circular interchangeable arc rails 31 can form a circular track.

[0081] In this embodiment, a lifting drive assembly 6 is also included for driving the first lifting frame 1 and the second lifting frame 2 to move vertically.

[0082] The lifting drive assembly 6 includes a lifting cylinder 61, a lifting piston 62, and a lifting drive rod 63. The lifting piston 62 is located inside the lifting cylinder 61, and the lifting drive rod 63 is vertically arranged with its bottom end fixedly connected to the lifting piston 62 and its top end extending out of the lifting cylinder 61.

[0083] The bottom of the first lifting frame 1 and the second lifting frame 2 are fixed to the top of the lifting drive rod 63.

[0084] In this embodiment, a hydraulic pump station is also included for supplying and extracting hydraulic oil into and from the lifting cylinder 61. The hydraulically driven first lifting frame 1 and second lifting frame 2 ensure the load-bearing capacity of the hopper assembly 4.

[0085] In this embodiment, the lifting drive component 6 is a conventional lifting hydraulic rod.

[0086] In this embodiment, as Figure 1 As shown, it also includes several partitioned platforms 7 with the same height as the transfer platform;

[0087] The first lifting frame 1 and the second lifting frame 2 are installed through the partition platform 7 and are slidably connected to it;

[0088] The transposition component 5 is installed through the partition platform 7 and can rotate freely.

[0089] In some embodiments, each partition platform 7 is provided with a set of switching components 5, which makes the floor areas between the partition platforms 7 more flexible when conveying building materials. For example, when the floor between two partition platforms 7 does not need to convey building materials, the switching components 5 can be kept in the closed state. At this time, the hopper components 4 on the lifting tray 3 will only rise and fall synchronously between the two floors with the first lifting frame 1 or the second lifting frame 2, without climbing or falling layer by layer, so that the overall use of building materials can be more flexible and convenient.

[0090] In this embodiment, the first lifting frame 1 includes at least two vertically arranged first support rods 11;

[0091] The second lifting frame 2 includes at least two vertically arranged second support rods 21;

[0092] Several lifting pallets 3 are fixed on the first lifting rod and the second lifting rod. Setting two or more first support rods 11 and second support rods 21 can make the lifting pallets 3 more stable after installation.

[0093] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
