Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a vertical transportation device. BACKGROUND

[0002] In the construction process, the transportation and hoisting of scattered materials such as masonry and mortar mainly rely on manual horizontal transfer of bucket carts and vertical hoisting of small hoppers. Small hoppers are usually welded from steel plates and have limited capacity, with small single hoisting capacity.

[0003] Due to the large demand for materials at the construction site, workers often overload the materials beyond the edge of the hopper to reduce the number of hoisting times. This overloading behavior easily leads to material scattering during hoisting and poses a risk of falling objects from a high altitude. Since the loading capacity is entirely determined by the experience of workers, it further exacerbates the safety hazards. In the horizontal transportation link, the hand-push bucket cart needs to be manually loaded and unloaded, and the transfer efficiency is low due to site conditions, especially in high-rise building construction, where materials need to be transferred multiple times to reach the work surface. SUMMARY

[0004] Therefore, the present application provides a vertical transportation device to solve the problem of poor hoisting efficiency in the prior art.

[0005] The present application provides a vertical transportation device, comprising:

[0006] a frame, the frame comprising a three-sided frame and a ground frame;

[0007] an in-out material assembly, the first in-out material assembly comprising a door leaf and a ramp, the door leaf being arranged on one side of the in-out material port of the frame and connected with the frame; the ramp being arranged below the first in-out material assembly and connected with the ground frame, the ramp rotating around the connection line between the ramp and the frame to form a blocking surface with the door leaf on one side of the frame.

[0008] Beneficial effects: The frame structure formed by the three-sided frame and the ground frame provides a stable support foundation for the vertical transportation device, ensuring the integrity and safety of the device during transportation. The design of the in-out material assembly includes a door leaf and a ramp, the door leaf is used to close the in-out material port to prevent accidental falling of materials during transportation, and the rotatable design of the ramp enables it to cooperate with the door leaf to form a blocking surface, effectively preventing materials from sliding out and improving the safety and convenience of loading and unloading materials. The rotation function of the ramp also enables the device to conveniently load and unload materials, enhancing the versatility and flexibility of the device.

[0009] In an alternative embodiment, the top of the frame is provided with an ear.

[0010] Beneficial effects: The ear enables the device to be quickly hoisted and moved by cranes, hoists and other equipment, reducing the difficulty and time cost of manual handling.

[0011] In an alternative embodiment, the door leaf is provided as two leaves and is connected to the frame by hinges, and a latch is provided on the door leaf for securing it.

[0012] Beneficial effects: The door leaf is provided as two leaves and is connected to the frame by hinges, and a latch is provided on the door leaf for securing it. This double-door structure makes the opening and closing of the material inlet and outlet more flexible, allowing the selection of opening a single leaf or double leaves according to actual needs, adapting to the loading and unloading needs of different sizes of materials. The setting of the latch further enhances the fixing effect of the door leaf, preventing accidental opening of the door leaf due to vibration or external force during transportation, ensuring the stability of the materials. The hinge connection method makes the opening and closing operation of the door leaf more smooth, reduces wear and tear, and prolongs the service life.

[0013] In an alternative embodiment, steel plates are covered on the three side frames and the ground frame of the frame, and the steel plates are fixed to the frame by welding.

[0014] Beneficial effects: By covering steel plates on the three side frames and the ground frame of the frame, the strength and durability of the device are enhanced. The welding of the steel plates to the frame ensures the stability of the structure, which can withstand a large impact force and load, suitable for the transportation of heavy materials. The covering of the steel plates also prevents the frame from rusting or corroding due to long-term exposure to harsh environments, prolonging the service life of the device.

[0015] In an alternative embodiment, lifting lugs are provided on the four corners of the frame, and the lifting lugs are welded to the frame.

[0016] Beneficial effects: The lifting lugs are provided on the four corners of the frame and are welded to the frame, the stress is more uniform during lifting, avoiding deformation or damage of the frame due to uneven stress. The welding connection method further enhances the bonding strength of the lifting lugs and the frame, ensuring stability under high load or frequent lifting conditions.

[0017] In an alternative embodiment, the length of the ramp is greater than the reserved height of the side of the frame.

[0018] Beneficial effects: By setting the length of the ramp to be greater than the reserved height of the side of the frame, the inclination angle of the material during loading and unloading is reduced, the safety of the operation is improved, and it is ensured that the ramp can fully extend to the ground or the loading and unloading platform, forming a smooth transition, facilitating the entry and exit of materials or equipment.

[0019] In an alternative embodiment, the surface of the ramp is provided with anti-skid lines, and the anti-skid lines are distributed along the length direction of the ramp.

[0020] Beneficial effects: The anti-slip texture on the surface of the ramp enhances its anti-slip performance, preventing materials or personnel from slipping due to wetness or incline during operation. The design of the anti-slip texture distributed along the length further enhances friction, ensuring smooth material movement and reducing the risk of accidental slippage.

[0021] In one optional embodiment, a rotating shaft is provided at the connection between the ramp and the ground frame. The two ends of the rotating shaft are connected to the ground frame through bearings, and a limiting block is provided on the rotating shaft to limit the rotation angle of the ramp.

[0022] Beneficial effects: The rotating shaft ensures the reliability of the ramp's rotation, and the limiting block ensures that the ramp can block the material when loading is complete, and guides the material in and out of the frame during the loading process.

[0023] In one alternative embodiment, a reinforcing rib is provided between the steel plate and the frame. The reinforcing rib is a strip steel plate that is welded to both the frame and the steel plate.

[0024] Beneficial effects: The addition of reinforcing ribs between the steel plates and the frame further enhances the load-bearing capacity and stability of the device. The reinforcing ribs are made of strip steel plates and welded to the frame and steel plates, forming a robust support structure that effectively distributes load pressure and prevents deformation or cracking of the steel plates.

[0025] In one alternative implementation, anti-slip pads are provided at the four bottom corners of the frame.

[0026] Beneficial effects: Anti-slip pads at the four corners of the frame bottom improve the stability and safety of the device during placement. These pads effectively increase friction between the frame and the ground, preventing the device from sliding or shifting due to external forces or vibrations during transportation or loading / unloading.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

Therefore, they should not be construed as limitations on this invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] During construction, the transportation and hoisting of loose materials such as masonry and mortar mainly rely on two methods: manual horizontal transfer using wheelbarrows and vertical hoisting using small hoppers. Small hoppers are typically welded from steel plates, with a simple structure and limited capacity, resulting in a small lifting capacity per trip, which is insufficient to meet the high-strength material requirements of the construction site. However, due to the high material consumption at the work site, workers often pile materials beyond the edge of the hopper to reduce the number of hoisting trips and improve efficiency, leading to overloading. This not only increases the load on the hopper but also makes it easy for materials to scatter during hoisting due to instability or swaying, thus posing a risk of falling objects from heights.

[0036] In horizontal transport, wheelbarrows are the primary means of transfer, requiring manual loading, unloading, and pushing, resulting in low efficiency and high labor intensity. Limited by factors such as narrow construction sites, uneven roads, or temporary obstacles, the efficiency of wheelbarrow transport is further reduced, especially in high-rise building construction, where the problem is more pronounced. Materials must undergo multiple transfers from the ground storage area to the work surface: first horizontally transported by wheelbarrow to the hoisting point, then vertically lifted using small hoppers, and finally manually transferred again to the construction location.

[0037] The following is combined Figure 1 The following describes embodiments of the present invention.

[0038] According to an embodiment of the present invention, a vertical transport device is provided, comprising:

[0039] Frame 1, which includes three side frames and a ground frame;

[0040] The first infeed / outfeed assembly 2 includes a door 21 and a ramp 22. The door 21 is located on one side of the infeed / outfeed port of the frame 1 and is connected to the frame 1. The ramp 22 is located below the first infeed / outfeed assembly 2 and is connected to the ground frame. The ramp 22 rotates about the line connecting the ramp 22 and the frame 1 as an axis, and cooperates with the door 21 to form a blocking surface on one side of the frame 1.

[0041] The frame structure 1, consisting of three side frames and a ground frame, provides a stable support foundation for the vertical transport device, ensuring its integrity and safety during transport. The inlet / outlet assembly 2 includes a door 21 and a ramp 22. The door 21 closes the inlet / outlet to prevent materials from accidentally falling during transport, while the rotatable design of the ramp 22 allows it to cooperate with the door 21 to form a blocking surface, effectively preventing materials from slipping out and improving the safety and convenience of loading and unloading. The rotatable function of the ramp 22 also facilitates material entry and exit, enhancing the device's versatility and flexibility.

[0042] The material feeding / discharging assembly 2 is located on the open side of the frame 1, including a door leaf 21 and a ramp 22. The door leaf 21 preferably has a two-leaf opening structure, hinged to the side frame 1 via heavy-duty hinges, with a hinge pivot diameter of not less than 20mm. Each door leaf 21 has a latch mechanism in the middle, which can be a manual latch or an automatic spring latch, with a locking depth of not less than 50mm. The ramp 22 is connected to the front edge of the ground frame via a rotating shaft, with self-lubricating bearings at both ends of the rotating shaft, preferably with an outer diameter of 50-80mm. The tilt angle of the ramp 220 can be adjusted within the range of 0°-45°. When rotated to a vertical position, its back surface forms a continuous blocking plane with the inner surface of the door leaf 210.

[0043] In some embodiments, combined with Figure 1As shown, the top of frame 1 is equipped with lifting lugs. These lugs allow the device to be quickly lifted and moved using cranes, gantry cranes, or other equipment, reducing the difficulty and time cost of manual handling. Each lifting lug is connected to frame 1 via a continuous circumferential weld, with a weld height of not less than 6mm. Optionally, the lifting lugs can be configured as detachable structures, connected to frame 1 via high-strength bolts.

[0044] Furthermore, lifting lugs are installed at the four corners of frame 1 and welded to frame 1. By placing the lifting lugs at the four corners of frame 1 and welding them to frame 1, the force is distributed more evenly during hoisting, preventing deformation or damage to frame 1 caused by uneven force distribution. The welding connection further enhances the bonding strength between the lifting lugs and frame 1, ensuring stability even under high loads or frequent hoisting.

[0045] In some embodiments, combined with Figure 1 As shown, the door leaf 21 consists of two leaves connected to the frame 1 via hinges. Each door leaf 21 has a latch for securing it. This double-door-leaf structure allows for more flexible opening and closing of the inlet and outlet, enabling the selection of either single or double leaf opening to accommodate the loading and unloading needs of materials of different sizes. The latches further enhance the securing effect of the door leaf 21, preventing accidental opening due to vibration or external force during transportation and ensuring the stability of the materials. The hinged connection makes the opening and closing of the door leaf 21 smoother, reduces wear, and extends its service life.

[0046] In some embodiments, steel plates are covered on the three side frames and the ground frame of frame 1, and the steel plates are fixed to frame 1 by welding. Covering the three side frames and the ground frame of frame 1 with steel plates enhances the strength and durability of the device. The welding fixing method of the steel plates to frame 1 ensures the stability of the structure, enabling it to withstand greater impact forces and loads, making it suitable for transporting heavy materials. The steel plate covering also prevents frame 1 from rusting or corroding due to long-term exposure to harsh environments, extending the service life of the device.

[0047] Furthermore, reinforcing ribs are provided between the steel plate and frame 1. These reinforcing ribs are strip-shaped steel plates, welded to both frame 1 and the steel plate. The addition of these reinforcing ribs between the steel plate and frame 1 further enhances the load-bearing capacity and stability of the device. The use of strip-shaped steel plates and their welded connection to frame 1 and the steel plate forms a robust support structure that effectively distributes load pressure and prevents deformation or cracking of the steel plate.

[0048] In some embodiments, the length of the ramp 22 is greater than the reserved height on the side of the frame 1. By setting the length of the ramp 22 to be greater than the reserved height on the side of the frame 1, the tilt angle of materials during loading and unloading is reduced, the safety of operation is improved, and it is ensured that the ramp 22 can extend fully to the ground or loading and unloading platform to form a smooth transition, facilitating the entry and exit of materials or equipment.

[0049] Specifically, the surface of the ramp 22 is provided with anti-slip textures, which are distributed along the length of the ramp 22. The anti-slip textures on the surface of the ramp 22 improve its anti-slip performance, preventing materials or personnel from slipping due to wetness or incline during operation. The design of the anti-slip textures being distributed along the length further enhances friction, ensuring smooth material movement and reducing the risk of accidental slippage.

[0050] Furthermore, a rotating shaft is provided at the connection between the ramp 22 and the ground frame. The two ends of the rotating shaft are connected to the ground frame through bearings, and a limiting block is provided on the rotating shaft to limit the rotation angle of the ramp 22. The rotating shaft ensures the reliability of the rotation of the ramp 22, and the limiting block ensures that the ramp 22 can act as a barrier when the loading is completed, and guides the material in and out of the frame 1 during the loading process.

[0051] In some embodiments, anti-slip pads are provided at the four bottom corners of the frame 1. Providing anti-slip pads at the four bottom corners of the frame 1 improves the stability and safety of the device during placement. The anti-slip pads effectively increase the friction between the frame 1 and the ground, preventing the device from sliding or shifting due to external forces or vibrations during transportation or loading / unloading.

[0052] The working process of the vertical transportation device of the present invention is as follows: When material loading and unloading operations are required, firstly, release the latch on the door 21 and open both doors 21 outward to the maximum opening; then, the operator pulls the handle on the ramp 22, causing the ramp 22 to rotate downward around the rotation axis to the working position. At this time, the lower end of the ramp 22 contacts the loading and unloading platform or the ground to form a continuous slope; the material smoothly enters the frame 1 along the ramp 22 by forklift, conveyor belt or manual means. When the loading reaches the preset position, the ramp 22 is rotated upward to reset to a vertical state, so that its back is flush with the inner surface of the door 21 to form a complete blocking surface; close the door 21 and insert the latch to complete the locking. At this time, the hoisting equipment lifts the entire device to the target position through the lifting lugs; after reaching the destination, repeat the above opening process, and the material can slide out along the ramp 22 or be unloaded by the mechanical device. Throughout the transportation process, the steel plate cladding and reinforcing ribs of frame 1 effectively resist external impacts, the anti-slip mats ensure the stability of the equipment, and the anti-slip texture guarantees the safety of personnel during loading and unloading. This workflow achieves closed-loop management of the entire process of material loading, unloading, transportation, and storage, significantly improving operational safety and efficiency.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
