Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a mobile building construction unloading platform. Background Technology

[0002] Currently, safety accidents are frequent in my country's construction industry, and various safety hazards are difficult to completely eliminate. Especially with the increase in high-rise buildings, the use of unloading platforms during the frame construction phase, before the installation of external construction elevators, is very common. Most current unloading platforms are cantilevered fixed platforms, which, after installation, must remain suspended on the outside of the building's scaffolding. They are fixed using steel cantilever and wire rope diagonal bracing. Workers must walk from inside the building to these cantilevered fixed platforms, resulting in prolonged exposure to dangerous areas on the outside. Furthermore, the connection between the platform and the building floors is difficult to close, significantly increasing safety hazards. Therefore, finding a new type of construction unloading platform has become a requirement of the construction industry. Utility Model Content

[0003] In order to solve the above-mentioned technical problems in the prior art, the present invention provides a mobile construction material unloading platform.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] This utility model provides a movable construction material unloading platform, including a material platform body, a cantilever support assembly, a guide rail, and a movable support assembly. The movable support assembly is disposed on the material platform body and includes a drive mechanism and at least one gear. The drive mechanism drives the gear to rotate. The guide rail is disposed on the cantilever support assembly and has a rack that meshes with the gear. The material platform body moves along the guide rail.

[0006] The movable construction material unloading platform provided by this utility model allows the material platform to be moved along the guide rail by manual operation of the drive mechanism, thereby moving the material platform to the horizontal plane of the building floor for unloading operations. This eliminates the need for manual labor to walk outside the building to carry out the work, greatly improving the safety of construction operations.

[0007] Based on the above technical solution, the present invention can also be improved in the following ways:

[0008] Furthermore, the drive mechanism includes a hand crank arm, an inner drive shaft, and an outer drive shaft. The outer drive shaft is sleeved on the inner drive shaft, and a bearing is provided between the inner drive shaft and the outer drive shaft. The outer drive shaft is connected to the hand crank arm, and the inner drive shaft is connected to the gear.

[0009] The beneficial effect of adopting the above-mentioned further technical solution is that the material table body can be moved along the guide rail by manually shaking the hand crank arm.

[0010] Furthermore, the material platform body is a box structure, the material platform body includes a side wall, and the side wall is provided with a groove for accommodating and fixing the hand crank arm.

[0011] The beneficial effects of adopting the above-mentioned further technical solution are as follows: when the material platform does not need to be moved or needs to be fixed in position, the hand crank arm is stored and fixed in the material groove, which plays a locking and limiting role, restricts the rotation of the hand crank arm, fixes the material platform body, and does not occupy the space of the material platform box, which facilitates the loading and unloading of materials; when the material platform needs to be moved, the hand crank arm is pulled out from the groove, and the material platform box can be moved by rotating the hand crank arm. When the material platform box is moved to the required position, the hand crank arm is pushed back into the groove.

[0012] Furthermore, a clamp is provided in the groove for fixing the hand crank arm.

[0013] The beneficial effect of adopting the above-mentioned further technical solution is that the clamp realizes the locking and fixing of the hand crank arm, and prevents the hand crank arm from coming out of the groove and causing the material platform box to move.

[0014] Furthermore, the drive mechanism also includes a hand grip, which is located at the end of the hand crank arm away from the external drive shaft, and the hand grip is connected to the hand crank arm via a pin.

[0015] The beneficial effects of adopting the above-mentioned further technical solution are as follows: by setting a hand grip, it is convenient to manually operate the drive mechanism. At the same time, the hand grip is connected to the end pin of the hand rocker arm, which makes it convenient for the hand rocker arm to be stored and fixed in the groove.

[0016] Furthermore, the movable support assembly includes a driving gear, a driven gear, and a second driven gear that mesh in sequence, and also includes a load-bearing traveling gear. The second driven gear and the load-bearing traveling gear are connected by a second bearing. The driving gear is connected to the inner drive shaft, and the load-bearing traveling gear moves along the rack.

[0017] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the transmission is carried out by a gear set, and the movement direction of the material platform box can be changed by changing the rotation direction of the hand crank arm; at the same time, the setting of the labor-saving gear set greatly reduces the manpower required to move the material platform box, and no electricity is required. Under the premise of ensuring functionality, the mechanism is simplified, the number of parts is reduced, and the failure rate is reduced, making it suitable for use in harsh environments such as construction sites.

[0018] Furthermore, it also includes at least one fixed support assembly, which includes a fixed support arm and a load-bearing traveling gear.

[0019] The beneficial effect of adopting the above-mentioned further technical solution is that by setting a fixed support assembly, the tilting and falling of the material platform box can be prevented.

[0020] Furthermore, the movable support assembly and / or fixed support assembly are equipped with an electronic scale, a position sensor, an audible and visual alarm device, and a wireless transmission element.

[0021] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: by setting up electronic scales, position sensors, audible and visual alarm devices, and wireless transmission elements, the location information, usage status, and mass of the stacked materials of the material platform can be obtained in real time. If the design load is exceeded, the audible and visual alarm devices will alert the operators, and the information will be transmitted to the designated system through the wireless transmission elements, thus achieving the effect of intelligent application.

[0022] Furthermore, a protective plate is provided on the outside of the material platform body, one end of which is connected to the material platform body and the other end is attached to the guide rail.

[0023] The beneficial effects of adopting the above-mentioned further technical solution are as follows: by setting a protective plate on the outside of the material platform body, the protective plate can move together with the material platform body along the guide rail, serving as a construction passage. When the material platform body is located outside the building, the protective plate can serve as a planar enclosure and a walking passage to prevent personnel and materials from falling.

[0024] Furthermore, the cantilever support assembly includes a plurality of first support beams spaced apart and a plurality of second support beams spaced apart, wherein the first support beams and the second support beams are orthogonally arranged.

[0025] The beneficial effect of adopting the above-mentioned further technical solutions is to improve the support strength.

[0026] Compared with the prior art, the present invention has the following technical effects:

[0027] The mobile construction material unloading platform provided by this utility model can move the material platform along the guide rail through a manually operated drive mechanism, thereby moving the material platform to the horizontal surface of the building floor for unloading operations. This eliminates the need for manual labor to walk to the outside of the building to carry out the work, greatly improving the safety of construction operations.

[0028] When the material platform body does not need to be moved or its position needs to be fixed, the hand crank arm can be pushed into the groove to store and fix it, thus playing a locking and limiting role. This restricts the rotation of the hand crank arm and fixes the drive gear without occupying the space of the material platform box, making it convenient for loading and unloading materials. When the material platform needs to be moved, the hand crank arm can be pulled out of the groove and rotated to move the material platform box. When the material platform box is moved to the required position, the hand crank arm can be pushed into the groove again.

[0029] The transmission is achieved by a gear set, and the hand crank can rotate in different directions. By changing the rotation direction of the hand crank, the movement direction of the material platform body can be changed, thereby enabling the material platform body to move in different directions along the guide rail, and thus move the material platform body closer to or away from the building.

[0030] A rack is installed on the guide rail, which meshes with the load-bearing traveling gear to push the material platform body to move on the guide rail. This method can ensure that the material platform body moves smoothly in the length direction of the guide rail. At the same time, the meshing and locking method can play a certain role in fixing the position of the material platform body and preventing the box structure from shaking in all directions.

[0039] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Although the description of this utility model will be presented in conjunction with preferred embodiments, this does not mean that the features of this utility model are limited to this embodiment. On the contrary, the purpose of describing the utility model in conjunction with the embodiments is to cover other options or modifications that may be derived based on the claims of this utility model. To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0040] See Figure 1-6 A movable construction material unloading platform includes a platform body 1, a cantilever support assembly 2, a guide rail 3, a movable support assembly 4, and a fixed support assembly 15. The movable support assembly 4 is mounted on the platform body 1 and includes a drive mechanism and a gear set. The drive mechanism drives the gear set to rotate. Specifically, the drive mechanism includes a hand crank arm 5, an inner drive shaft 6, an outer drive shaft 7, and a handle 10. The outer drive shaft 7 is sleeved on the inner drive shaft 6, and a bearing 8 is provided between the inner drive shaft 6 and the outer drive shaft 7. The outer drive shaft 7 is connected to the hand crank arm 5, and the inner drive shaft 6 is connected to the gear. The handle 10 is located at the end of the hand crank arm 5 away from the outer drive shaft 7. The handle 10 is connected to the end of the hand crank arm 5 via a pin 14, and the handle 10 can rotate around the end of the hand crank arm 5; the gear set includes a driving gear 11, a driven gear 12, and a driven gear 4 meshing in sequence, and also includes a load-bearing traveling gear 13. The driven gear 12 is connected to the material platform body 1 via a connecting bearing seat 22. The driven gear 4 and the load-bearing traveling gear 13 are connected via a bearing 21. The inner drive shaft 6 is connected to the driving gear 11. The inner drive shaft 6 drives the driving gear 11 to rotate. The driving gear 11 drives the driven gear 12 to rotate. The driven gear 12 drives the driven gear 4 to rotate. The driven gear 4 drives the load-bearing traveling gear 13 to rotate, thereby realizing the movement of the material platform body 1;

[0041] The drive gear 11 and driven gear 12 adopt a large gear ratio design. On the one hand, it is to save effort when driven manually, and on the other hand, it is to meet the positional accuracy requirements when locking, so as to achieve fine adjustment of the position of the material platform body 1. That is, the material platform body 1 moves a small distance when the drive gear 11 rotates one revolution, so as to ensure that the deviation between the actual position of the material platform body 1 and the required position when locking is not too large.

[0042] The cantilever support assembly 2 is made of I-beams and includes several spaced-apart first support beams 16 and several spaced-apart second support beams 17. Each first support beam 16 and each second support beam 17 is orthogonally arranged and connected and fixed by welding or bolting to form a stable and secure cantilever support assembly 2. The top of each first support beam 16 is equipped with a baffle and a rubber buffer pad to reduce the impact of the material platform body 1 on the first support beam 16. The guide rail 3 is mounted on the first support beam 16 and is U-shaped. The material platform body 1 is shaped with a rack 20 at the bottom for easy fixing and movement. The guide rail 3 is equipped with a rack 20 that meshes with the load-bearing traveling gear 13, allowing the material platform body 1 to move along the guide rail 3. By drilling holes in the upper flange of the I-beam and drilling and tapping holes in the bottom of the guide rail 3, the guide rail 3 and the I-beam are connected by bolts or rivets, increasing the overall rigidity, avoiding the adverse effects of welding on the stress of the I-beam, and ensuring the load-bearing capacity. When the guide rail 3 or the I-beam is damaged, the undamaged parts can be disassembled and reused, reducing wear and tear.

[0043] The material platform body 1 is a box-shaped structure, including a side wall. A groove 9 is provided on the side wall for accommodating and fixing the hand crank arm 5. A clamp 19, which is a spring-loaded clamp, is provided within the groove 9 to fix the hand crank arm 5. A second groove is provided at the end of the hand crank arm 5 near the pin 14 for storing the handle 10. During use, when the material platform body 1 does not need to be moved, or when the material platform body 1 is moved to a position where it needs to be fixed, the handle 10 is manually released, and under gravity, it falls into and is stored in the second groove. Then, the hand crank arm 5 is manually pushed, causing the outer drive shaft 7 to move relative to the inner drive shaft 6 towards the groove 9, so that the hand crank arm 5 is embedded in the groove 9 and fixed by the clamp 19. When it is necessary to move the material platform body 1, the manual person pulls the handle 10 out of the second groove, grips the handle 10, and pulls the hand crank arm 5 out of the groove 9. The manual person rotates the hand crank arm 5, which drives the drive gear 11, the driven gear 12, and the load-bearing traveling gear 13 to rotate. The load-bearing traveling gear 13 moves on the rack 20, thus moving the material platform body 1. When the material platform body 1 has moved to the required position, the hand crank arm 5 is pushed back into the groove 9. The hand crank arm 5 can rotate in two directions, which enables the load-bearing traveling gear 13 to move in two directions on the rack 20, thereby moving the material platform body 1 closer to or away from the building.

[0044] The fixed support assembly 15 is provided in five sets, and the five sets of fixed support assemblies 15 have the same structure. Taking any one of the sets as an example, the fixed support assembly 15 includes a fixed support arm 23 and a load-bearing traveling gear 24. The fixed support arm 23 is connected to the material platform body 1, and the fixed support arm 23 and the load-bearing traveling gear 24 are connected by a bearing 3. The material platform body 1 moves, thereby driving the load-bearing traveling gear 24 to move on the rack 20.

[0045] The movable support assembly 4 and the fixed support assembly 15 are equipped with electronic scales, position sensors, audible and visual alarm devices, and wireless transmission components. The electronic scales accurately measure the weight of the stacked materials, transmitting the data to a data center via IoT technology. After setting a load limit, the actual material weight is compared, and an alarm is triggered if the limit is exceeded. A protective plate 18 is provided on the exterior of the material platform body 1, positioned between the material platform body 1 and the building. One end of the protective plate 18 is connected to the material platform body 1, and the other end rests on the guide rail 3. This protective plate 18 serves as a planar enclosure and a walking passage, effectively preventing personnel and materials from falling. It can also move with the material platform body 1. The protective plate 18 is made of steel.

[0046] During use, after the cantilever support assembly 2, guide rail 3, and material platform body 1 are assembled on the ground, they are hoisted to the floor of the building. The first support beam 16 of the cantilever support assembly 2 is fixed by the pre-embedded steel reinforcement ring in the building. One end of the steel wire rope is tied to the lifting lug 25 of the cantilever support assembly 2, and the other end is tied to the pre-embedded lifting ring in the building. When materials are transported out of the building, the workers pull the hand crank arm 5 out of the groove 9 on the side wall of the material platform box, rotate the hand crank arm 5 to drive the drive gear 11, the drive gear 11 and the driven gear 12 rotate, the driven gear 12 drives the load-bearing traveling gear 13 to rotate, and the load-bearing traveling gear 13 drives the material platform body 1 to move along the guide rail 3. When the material platform body 1 moves to the outside of the building and is in place, if it is necessary to fix the position of the material platform body 1, the hand crank arm 5 is rotated to the position corresponding to the groove 9 on the side wall, and the hand crank arm 5 is pushed into the groove 9 to lock and fix the drive gear 11, thereby ensuring that the material platform body 1 no longer moves.

[0047] When transporting materials, if the material is to be transported into a building, the workers first move the material platform 1 to the outside of the building, lower the protective plate 18, and then enter the material platform 1 through the protective plate 18 to work. Vertical transportation equipment such as tower cranes will lift the material into the material platform 1. Afterwards, the workers will move the material platform 1 into the building to unload the material. If the material needs to be transported out of the building, the workers will move the material platform 1 into the building. After the workers move the material into the material platform 1, they will operate the hand crank 5 to move the material platform 1 to the outside of the building for hoisting operations.

[0048] This mobile construction material unloading platform greatly reduces the time workers are exposed to dangerous high-altitude work areas, significantly improving safety. At the same time, through electronic weighing components, position sensors, and wireless transmission components, it can collect key information data of the material box at any time, facilitating control by the operating unit and personnel and reducing safety hazards.

[0049] When staff are off duty and the platform is not in use, or in case of sudden severe weather, the platform body 1 can be moved into the building and the hand crank arm 5 can be locked according to the operating procedure. This can effectively reduce the windward side and prevent accidents such as tilting or overturning of the platform body 1, greatly improving safety.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
