Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a multi-functional hoisting device for building construction. Background Technology
[0002] In the construction process, hoisting is a crucial step, requiring the transport of various building materials, such as boards, pipes, and reinforcing bars, to designated locations. Existing hoisting equipment often has a relatively fixed design, unable to flexibly adapt to building materials of different shapes, sizes, and weights. For example, for non-standard sized boards or long pipes, conventional hoisting equipment struggles to find suitable lifting points, hindering safe and efficient hoisting operations and limiting its application in diverse construction scenarios. Many traditional hoisting devices employ simple methods for securing materials during transport, lacking effective cushioning and anti-sway designs. This makes hoisted materials prone to swaying, tilting, or even falling, seriously threatening the safety of personnel and the normal operation of equipment on construction sites. Therefore, we have introduced a multi-functional hoisting device for construction. Utility Model Content
[0003] The main objective of this invention is to provide a multi-functional hoisting device for building construction, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A multi-functional hoisting device for building construction includes a support plate. Lockable movable wheels are fixedly connected to the four lower corners of the support plate. An upper plate is fixedly connected to the upper left and upper right parts of the support plate. A drive device is fixedly connected to the right end of the upper plate. An elongated groove is opened in the middle of the upper end of the support plate. Two handle grooves are opened in the middle of the left and right ends of the support plate. A load-bearing device is fixedly connected to the lower end of the drive device.
[0006] The driving device includes a drive motor whose output end passes through the upper plate and is fixedly connected to a take-up and release rod. Limiting circular plates are fixedly connected to the left and right sides of the outer surface of the take-up and release rod. A steel lock rope is wound around the middle of the outer surface of the drive motor. A connecting shaft block is fixedly connected to the other end of the steel lock rope. A lifting plate is fixedly connected to the lower end of the connecting shaft block. Limiting rods are inserted through the upper left and upper right sides of the lifting plate. Buffer damping springs are sleeved on the lower parts of the outer surfaces of the two limiting rods. The drive motor is fixedly connected to the middle of the right side of the upper plate.
[0007] Preferably, the bearing device includes four mounting rods, the lower ends of the four mounting rods are fixedly connected to a bearing frame, the upper front part and the upper rear part of the bearing frame are fixedly connected to auxiliary components, the upper front part and the upper rear part of the bearing frame are both provided with arc-shaped grooves, and the four mounting rods are respectively inserted and connected around the lower end of the lifting plate.
[0008] By adopting the above technical solution, four mounting rods are evenly distributed and connected to the lifting plate and the load-bearing frame, ensuring that the load-bearing frame can stably follow the movement of the lifting plate, so that the load-bearing device can maintain balance during the lifting process, improving the stability of the overall structure and enabling it to withstand larger weights of building materials.
[0009] Preferably, the auxiliary component includes an arc-shaped plate, with fixing ropes fixedly connected to the upper perimeter of the arc-shaped plate, an anti-slip layer fixedly connected to the inner wall of the arc-shaped plate, and the arc-shaped plate fixedly connected to the upper front end of the support frame.
[0010] By adopting the above technical solution, the arc-shaped structure of the arc plate matches the shape of cylindrical materials such as pipes and steel bars, which can better fit and support these materials. The fixing rope can further bind and fix the materials to prevent them from slipping due to shaking during hoisting, thus improving the safety of the materials during hoisting.
[0011] Preferably, the arc-shaped plate has an arc-shaped structure, and the arc-shaped plate and the arc-shaped groove have the same longitudinal horizontal height.
[0012] By adopting the above technical solution, the arc plate and the arc groove are at the same height, which can form a continuous and stable support surface when placing materials such as pipes and steel bars, avoiding the tilting or instability of materials in the front and back directions. This design further enhances the load-bearing effect on cylindrical materials, making them more stable during hoisting and reducing safety hazards caused by material shaking.
[0013] Preferably, the structure of the auxiliary component on the front side is the same as that of the auxiliary component on the rear side and they are symmetrically distributed front to back.
[0014] By adopting the above technical solution, the identical auxiliary components symmetrically distributed at the front and rear ensure that the pipes, steel bars and other materials are supported evenly at both ends of the load-bearing frame, avoiding the displacement or falling of materials during hoisting due to uneven force distribution. This symmetrical structure helps maintain the balance of the entire load-bearing device during hoisting, improving the stability and safety of the device.
[0015] Preferably, the upper and lower ends of the two limiting rods are fixedly connected to the upper and lower walls of the support plate, respectively, and the two limiting rods are symmetrically distributed from left to right.
[0016] By adopting the above technical solution, the steel lock rope is located in the long groove, which can avoid interference and entanglement with other components during the winding and unwinding process, and ensure the smooth winding and unwinding of the steel lock rope.
[0017] Preferably, the left end of the take-up and release rod is movably connected to the middle of the left wall of the upper plate via a bearing, and the steel lock rope is located in the long groove.
[0018] By adopting the above technical solution, the steel lock rope is located in the long groove, which can avoid interference and entanglement with other components during the winding and unwinding process, and ensure the smooth winding and unwinding of the steel lock rope.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. In this utility model, the supporting frame can directly place small building materials, and its relatively flexible structure can better support non-standard sized materials. At the same time, the arc plate and arc groove on the supporting frame can provide a suitable placement and support method for long pipes and other materials, find a stable lifting point, and thus meet the hoisting needs of different materials in diverse building construction scenarios. This greatly improves the adaptability of the device to various building materials. The device can fix pipes of different diameters and steel bars of different specifications by adjusting the fixing rope, avoiding the problem of being unable to hoist due to differences in material specifications, and broadening its application scope in building construction.
[0021] 2. In this utility model, the design of the drive device, through the cooperation of the limiting rod and the lifting plate, provides precise guidance for the lifting process. The upper left and right parts of the lifting plate are respectively inserted on the symmetrically distributed limiting rods, so that the lifting plate can only move up and down in the vertical direction, effectively avoiding possible swaying and deviation during the lifting process. At the same time, the buffer damping spring sleeved on the lower part of the outer surface of the limiting rod can absorb and buffer the impact force when the lifting plate descends and return to its original shape when it rises, further reducing the vibration of the entire device during the lifting process, ensuring the stability of the bearing device and the carried items during the lifting process, and greatly reducing the risk of damage to materials caused by swaying. The mounting rods of the bearing device firmly connect the bearing frame and the lifting plate. The four mounting rods are evenly distributed to ensure the balance of the bearing frame during the lifting process and prevent tilting due to uneven force. In addition, the longitudinal horizontal height of the arc plate and the arc groove are the same, and the auxiliary component structures on the front and rear sides are the same and symmetrically distributed. This symmetrical structure makes the placement of pipe and steel bar items on the bearing frame more stable, further enhancing the overall stability during hoisting.
[0022] 3. In this utility model, the limiting circular plate in the drive device is fixed on the left and right sides of the outer surface of the take-up and release rod. When the take-up and release rod rotates to take up and release the steel lock rope, it can effectively limit the range of left and right movement of the steel lock rope, preventing the steel lock rope from slipping or deviating from the take-up and release rod during the take-up and release process. This design greatly improves the stability and reliability of the steel lock rope take-up and release, avoids safety accidents such as material falling due to steel lock rope failure, and ensures the life safety of construction site personnel and the normal operation of equipment. The auxiliary component of the bearing device increases the friction with pipes and steel bars through the anti-slip layer on the inner wall of the arc plate to prevent the items from slipping. At the same time, the fixing ropes around the upper part of the arc plate are used to tie and fix the items, further ensuring that the materials will not fall due to shaking or tilting during the hoisting process, providing a more reliable safety guarantee for the construction site and effectively reducing safety risks.

[0032] Please see Figure 1-5 This utility model provides a technical solution:
[0033] A multi-functional hoisting device for building construction includes a support plate 1. Lockable movable wheels 2 are fixedly connected to the four corners of the lower end of the support plate 1. An upper plate 3 is fixedly connected to the upper left and upper right parts of the support plate 1. A drive device 4 is fixedly connected to the right end of the upper plate 3. A long groove 5 is opened in the middle of the upper end of the support plate 1. Two handle grooves 7 are opened in the middle of the left and right ends of the support plate 1. A load-bearing device 6 is fixedly connected to the lower end of the drive device 4.
[0034] In this embodiment, the drive device 4 includes a drive motor 41 whose output end passes through the upper plate 3 and is fixedly connected to a take-up and release rod 43. The left and right sides of the outer surface of the take-up and release rod 43 are fixedly connected to limit plates 42. A steel lock rope 44 is wound around the middle of the outer surface of the drive motor 41. The other end of the steel lock rope 44 is fixedly connected to a connecting shaft block 47. The lower end of the connecting shaft block 47 is fixedly connected to a lifting plate 48. Limit rods 45 are inserted through the upper left and upper right sides of the lifting plate 48. Buffer damping springs 46 are sleeved on the lower part of the outer surface of the two limit rods 45. The drive motor 41 is fixedly connected to the middle of the right side of the upper plate 3. The upper and lower ends of the two limit rods 45 are fixedly connected to the upper and lower walls of the support plate 1, respectively. The two limit rods 45 are symmetrically distributed from left to right. The left end of the take-up and release rod 43 is movably connected to the middle of the left wall of the upper plate 3 through a bearing. The steel lock rope 44 is located in the long groove 5.
[0035] Through the above scheme: the drive motor 41 is fixedly connected to the middle of the right end of the upper plate 3. After starting, its output end rotates, passing through the upper plate 3 and driving the take-up and release rod 43 fixedly connected to it to rotate. The take-up and release rod 43 rotates under the drive of the drive motor 41. The steel lock rope 44 is wound around the middle of its outer surface. The take-up and release of the steel lock rope 44 is realized by forward and reverse rotation. The left end of the take-up and release rod 43 is movably connected to the middle of the left plate wall of the upper plate 3 through a bearing to ensure smooth rotation and realize the orderly take-up and release of the steel lock rope 44, thereby controlling the lifting height of the lifting plate 48 and the load. Moreover, the bearing connection reduces the friction during rotation and improves the operating efficiency of the device. The limiting circular plate 42 is fixedly connected to the left and right sides of the outer surface of the take-up and release rod 43. During the rotation of the take-up and release rod 43 to take up and release the steel lock rope 44, it restricts the range of left and right movement of the steel lock rope 44, preventing it from slipping or deviating from the take-up and release rod 43 during the process. This ensures the stability and reliability of the steel lock rope 44 during take-up and release, improving the safety of the device. The steel lock rope 44 is wound around the middle of the outer surface of the take-up and release rod 43, and its other end is fixedly connected to a connecting shaft block 47. As the take-up and release rod 43 rotates, the steel lock rope 44 is taken up and released, thereby driving the connecting shaft block 47 and the connected lifting plate 48 to move up and down. Located within the long slot 5, the lifting plate 44 avoids interference with other components. The lifting plate 48 is connected to the steel locking rope 44 via a connecting shaft block 47. Its upper left and right ends are respectively interlaced with two symmetrically distributed limiting rods 45. When the steel locking rope 44 is retracted or extended, the lifting plate 48 moves up and down along the limiting rods 45. The upper and lower ends of the limiting rods 45 are fixedly connected to the upper and lower walls of the support plate 1, respectively. The lifting plate 48, interlaced with the limiting rods 45, provides guidance for its lifting and lowering, restricting its movement to the vertical direction. A buffer damping spring 46 is sleeved on the lower part of the outer surface of the limiting rod 45. When the lifting plate 48 descends, the buffer damping spring... The damping spring 46 is compressed to absorb and buffer the impact force during the descent of the lifting plate 48. When the lifting plate 48 rises, the damping spring 46 returns to its original state. The drive device 4 uses the drive motor 41 as the power source. After the drive motor 41 starts, it drives the take-up and release rod 43 to rotate. The take-up and release rod 43 ensures the orderly take-up and release of the steel lock rope 44 through the limiting circular plate 42. The take-up and release of the steel lock rope 44 drives the connecting shaft block 47 and the lifting plate 48 to move. Under the guidance of the symmetrically distributed limiting rods 45, the lifting plate 48 rises and falls smoothly in the vertical direction. The damping spring 46 sleeved on the limiting rod 45 buffers the impact force during the lifting process.
[0036] In this embodiment, the supporting device 6 includes four mounting rods 62. The lower ends of the four mounting rods 62 are fixedly connected to a supporting frame 61. The upper front and upper rear ends of the supporting frame 61 are fixedly connected to auxiliary components 64. The upper front and upper rear ends of the supporting frame 61 are both provided with arc-shaped grooves 63. The four mounting rods 62 are respectively inserted and connected around the lower end of the lifting plate 48. The auxiliary components 64 include an arc-shaped plate 641. The upper periphery of the arc-shaped plate 641 is fixedly connected to a fixing rope 643. The inner wall of the arc-shaped plate 641 is fixedly connected to an anti-slip layer 642. The arc-shaped plate 641 is fixedly connected to the upper front end of the supporting frame 61. The arc-shaped plate 641 has an arc-shaped structure. The arc-shaped plate 641 and the arc-shaped groove 63 have the same longitudinal horizontal height. The structure of the auxiliary components 64 on the front side is the same as that on the rear side and they are symmetrically distributed front and back.
[0037] Through the above scheme: the support frame 61 is located at the bottom of the entire support device 6, and is connected to the lifting plate 48 through four mounting rods 62, moving with the lifting plate 48 as it rises and falls. It is used to place building materials such as boards. The auxiliary component 64 consists of an arc-shaped plate 641, an anti-slip layer 642, and a fixing rope 643. The arc-shaped plate 641 is fixed to the upper front and rear ends of the support frame 61, and has an arc-shaped structure with the same longitudinal horizontal height as the arc-shaped groove 63. It is used to support pipes and steel bars. The anti-slip layer 642 on the inner wall of the arc-shaped plate 641 increases the friction with the pipes and steel bars to prevent them from slipping. The fixing ropes 643 around the upper end of the arc-shaped plate 641 can bind and fix the pipes and steel bars. The arc-shaped groove 63 is opened at the upper front and rear of the support frame 61, and cooperates with the arc-shaped plate 641 to provide support for the pipes and steel bars. To provide a more fitting placement space and further stabilize items, the support device 6, when in operation, uses the mounting rod 62 to securely connect the support frame 61 to the lifting plate 48, allowing the support frame 61 to move with the lifting plate 48. For small building materials, the boards can be placed directly inside the support frame 61 for hoisting. For pipes and steel bars, they are placed on the arc-shaped plates 641 at the upper front and rear ends of the support frame 61. The arc-shaped plates 641 and the arc-shaped grooves 63 cooperate to provide a close fit for the items. The anti-slip layer 642 on the inner wall of the arc-shaped plates 641 increases friction and prevents items from slipping. At the same time, the items are tied and fixed using the fixing ropes 643 around the upper part of the arc-shaped plates 641. Through the coordinated work of all components, the support device 6 can safely and stably support different types of building materials, meeting the hoisting needs in construction.
[0038] It should be noted that this utility model is a multi-functional hoisting device for building construction. When this multi-functional hoisting device is working, firstly, the lockable movable wheels 2 are unlocked, the support plate 1 is pushed to the designated position, and then the lockable movable wheels 2 are locked and fixed. When small building materials need to be hoisted, they can be placed in the bearing frame 61. When pipes or steel bars are used, they are placed on the two arc-shaped plates 641 at the upper front and upper rear of the bearing frame 61 and tied with the fixing rope 643. The drive motor 41 in the drive device 4 is started, and the output end of the drive motor 41 drives the take-up and release rod 43 to rotate. Since the left and right sides of the outer surface of the take-up and release rod 43 are fixedly connected with limit plates 42, the steel lock rope 44 can be prevented from shifting left and right during the take-up and release process. As the take-up and release rod 43 rotates, the steel lock rope 44 wrapped in the middle of the outer surface of the drive motor 41 begins to take up and release. The connecting shaft block 47 connected to the other end of the steel lock rope 44 drives the lifting plate 48. The lifting device 6 and the carried items move up and down along the limiting rod 45. During the lifting process, the limiting rod 45, which is interlaced between the upper left and right sides of the lifting plate 48, plays a guiding role and enhances the stability of the lifting. The buffer damping spring 46 sleeved on the lower part of the outer surface of the two limiting rods 45 can reduce the impact during the lifting process. The four mounting rods 62 of the carrying device 6 are respectively interlaced around the lower end of the lifting plate 48. The carrying frame 61 is connected to the lifting plate 48 through the mounting rods 62 to carry the items. At the same time, the arc plate 641 has an arc structure and is at the same longitudinal horizontal height as the arc groove 63. The auxiliary components 64 on the front and rear sides have the same structure and are symmetrically distributed front and rear, further stabilizing the placement of pipe and steel bar items. The left end of the take-up and release rod 43 is movably connected to the middle of the left plate wall of the upper plate 3 through the bearing to ensure its smooth rotation. The steel lock rope 44 is located in the long groove 5 to avoid interference with other components during the movement.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
