Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting platform equipment technology, and in particular to a hoisting hook platform for construction engineering. Background Technology
[0002] Lifting hook platforms for construction engineering are essential equipment for material handling and personnel operations in construction. Their structural design must balance safety, applicability, and ease of operation. The platform uses a rectangular frame with fixed curvature hooks, guardrails around the frame, and casters or fixed supports at the bottom. The hook mechanism often uses a single-axis anti-detachment baffle to prevent detachment. The platform's leveling relies on simple screws or shims, and the platform surface uses checkered steel plates to improve slip resistance. With the development of industrialized construction, the demand for lifting prefabricated components has increased. The platform needs to be adaptable to different specifications of lifting tools and complex working environments. Its mechanical structure needs further optimization in terms of load distribution, rapid leveling, and ease of access to meet the actual needs of efficient construction and safe operation.
[0003] A search revealed Chinese Patent Publication No. CN218714961U, which discloses an adjustable-spacing integrated hoisting platform. The platform includes a main platform, embedded parts pre-embedded in the concrete inner cylinder wall, and multiple load-bearing beams erected below the main platform. Each load-bearing beam comprises a main beam and two secondary beams, distributed at both ends of the main beam and movable along its length to adjust its length. Support legs are provided at the outer ends of the secondary beams. Hangers are installed on the embedded parts, and load-bearing pins are provided on the hangers. Hooks matching the load-bearing pins are formed at the outer ends of the support legs. This adjustable-spacing integrated hoisting platform can be adjusted to meet the construction needs of concrete inner cylinder structures of different specifications. The platform is highly versatile, eliminating the need for large-scale cutting and welding on-site, ensuring safety while improving construction efficiency. However, in actual use, the railings above the platform make it inconvenient for personnel to move goods, thus affecting efficiency. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a hoisting hook platform for construction engineering, which aims to improve the problem of inconvenience for personnel to move goods due to the railings above the platform in the existing technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hoisting hook platform for construction engineering, comprising a platform plate, with railing plates fixedly connected to the top left and right sides of the platform plate, a double door mechanism provided on the top front side of the platform plate, the double door mechanism being a double door for facilitating personnel entry and exit, an adjustment mechanism provided on the top of each of the two railing plates, the adjustment mechanism being for adapting to platforms of different sizes, a rotating component provided on the rear side of the platform plate, and a limit component provided on the top of the platform plate;
[0006] The double-door mechanism includes a U-shaped plate. The bottom of the U-shaped plate is fixedly connected to the top front side of the platform plate. A hollow block is fixedly connected to the rear top of the U-shaped plate. Hollow sliding plates are slidably connected to the left and right sides of the inner wall of the hollow block. Limiting rods are slidably connected to the front left and right sides of the hollow sliding plates. Safety doors are fixedly connected to the front ends of the two limiting rods on the left and right sides. Compression springs are fixedly connected to the rear left and right sides of the safety doors. Closing components are provided on the opposite sides of the two safety doors. A driving component is provided on the rear side of the U-shaped plate.
[0007] The above technical solution works as follows: When personnel need to enter or exit the platform, the servo motor in the drive assembly is activated, which drives the gear to rotate. The meshing relationship between the gear and the rack causes the hollow sliding plates on both sides to move relative to or away from each other, thereby moving the safety door together. When the inclined groove above the safety door begins to contact the inclined surface above the U-shaped plate, the safety door is pushed by the compression spring and locked onto the U-shaped plate by the inclined groove and the inclined surface, thus completing the closing operation. To open, the servo motor is simply driven in reverse to reset the safety door and open it, thus achieving synchronous opening and closing of the safety door and avoiding the risk of center of gravity shift when opening a single door.
[0008] As a further description of the above technical solution:
[0009] The adjustment mechanism includes multiple fixing rings, the bottoms of which are fixedly connected to the front and rear sides of the top of the two railing plates respectively. A steel cable is fixedly connected to the outer wall of the fixing ring. A connecting rod is provided on the top of the platform plate. T-shaped blocks are slidably connected to the front and rear sides of the outer wall of the connecting rod. Rotating perforated plates are rotatably connected to the left and right sides of the T-shaped blocks. The inner wall of the rotating perforated plates is engaged with the outer wall of the top of the steel cable. Connecting hanging rings are fixedly connected to the left and right sides of the top of the two T-shaped blocks. A fixing component is provided on the outer wall of the T-shaped blocks.
[0010] Through the above technical solution: when the size of the hoisted platform plate 1 is the same, the T-blocks on both sides can be moved to the position above the connecting rod. Then, the fixing bolts are passed through the corresponding limit holes and fixed through the fixing components, thereby fixing the adjusted length. The hoisting equipment hooks above the connecting ring, thereby hoisting the adjusted T-blocks and connecting rods. The rotation of the perforated plate above the T-blocks allows the T-blocks to better adapt to platform plates of different sizes. Driven by the fixing ring and steel cable, the entire platform plate can be hoisted, thus enabling the hoisting of platform plates of different sizes.
[0011] As a further description of the above technical solution:
[0012] The rotating assembly includes a rotating plate, the bottom of the outer wall of the rotating plate is rotatably connected to the rear side of the platform plate, and a limiting block is fixedly connected to the rear end of each adjacent side of the two railing plates. A locking post is slidably connected to the inner wall of the limiting block, and the bottom of the outer wall of the two locking posts is respectively locked to the top left and right sides of the rotating plate.
[0013] The above technical solution allows for the following: when the platform is hoisted to the required height, the locking column can be pulled out, allowing it to engage with the rotating plate. The rotating plate is then rotated to contact the corresponding floor, making it easier to remove oversized items from above the platform.
[0014] As a further description of the above technical solution:
[0015] The limiting component includes multiple limiting holes, the outer walls of which are formed on the top of the platform plate, and the inner walls of which are threaded with threaded hooks. A cross-shaped reinforcing plate is fixedly connected to the bottom of the platform plate.
[0016] The above technical solution involves threading the threaded hooks into the corresponding limiting holes to limit the connection rope of the fixed equipment, and improving the structural strength of the platform plate 1 by adding a cross-shaped reinforcing plate.
[0017] As a further description of the above technical solution:
[0018] The closing assembly includes two inclined grooves, the outer walls of which are respectively opened on opposite sides of the two hollow sliding plates, and inclined surfaces are opened on the left and right sides of the inner wall of the U-shaped plate.
[0019] The above technical solution, with its inclined groove and inclined surface, allows the safety door to better engage above the U-shaped plate when closed.
[0020] As a further description of the above technical solution:
[0021] The drive assembly includes a servo motor. The front side of the servo motor is fixedly connected to the middle of the rear side of the hollow block. The output end of the servo motor passes through the rear side of the hollow block and is fixedly connected to a gear. The upper and lower sides of the outer wall of the gear are meshed with racks. The two racks are fixedly connected to the outer walls of the corresponding hollow slide plates on opposite sides.
[0022] Through the above technical solution: the start of the servo motor will drive the gear to rotate, and under the action of the meshing relationship between the gear and the rack, the racks on both sides will drive the corresponding hollow slides to move relative to or away from each other.
[0023] As a further description of the above technical solution:
[0024] The fixing component includes multiple limiting holes, the outer walls of which are respectively opened on the left and right sides of the outer walls of the two T-shaped blocks. The inner walls of the limiting holes are provided with fixing bolts, the outer walls of which penetrate the inner walls of the connecting rod and engage with the inner walls of the corresponding limiting holes.
[0025] The above technical solution involves threading the threaded hooks into the corresponding limiting holes to limit the connection rope of the fixed equipment.
[0026] As a further description of the above technical solution:
[0027] A limiting strip is fixedly connected to the middle of the rear side of the inner wall of the hollow block, and the left and right sides of the outer wall of the limiting strip are respectively slidably connected to the rear side of the corresponding hollow slide plate.
[0028] The above technical solution utilizes limiting strips to enable the hollow sliding plates on both sides to move more smoothly and stably.
[0029] This utility model has the following beneficial effects:
[0030] 1. In this utility model, by starting the servo motor in the drive assembly, the gear is driven to rotate, causing the hollow slide plate to move, and then the safety door is moved. When the inclined groove of the safety door contacts the inclined surface of the U-shaped plate, the safety door is locked above the U-shaped plate under the push of the compression spring, completing the closing of the door. The reverse drive of the servo motor causes the safety door to reset, thereby achieving synchronous opening and closing and avoiding the risk of center of gravity shift.
[0031] 2. In this utility model, by moving the T-shaped block above the connecting rod, the adjusted length is fixed on the limiting hole using fixing bolts. The hook of the hoisting equipment is used above the connecting ring to lift the adjusted T-shaped block and connecting rod. The perforated plate is rotated to make the T-shaped block adapt to platform plates of different sizes. Under the action of the fixing ring and steel cable, the platform plate is lifted, thereby realizing the hoisting of platform plates of different sizes. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0041] Reference Figure 1 , Figure 4 and Figure 6This utility model provides an embodiment of a hoisting hook platform for construction engineering, including a platform plate 1, which is the basic structure of the entire hoisting platform. Guardrail plates 4 are fixedly connected to the top left and right sides of the platform plate 1, improving the protection of the platform's sides.

The bottom of the U-shaped plate 201 is fixedly connected to the top front side of the platform plate 1. A hollow block 202 is fixedly connected to the rear top of the U-shaped plate 201. Hollow slide plates 203 are slidably connected to the left and right sides of the inner wall of the hollow block 202. Limit rods 204 are slidably connected to the front left and right sides of the hollow slide plates 203. Safety doors 205 are fixedly connected to the front ends of the two limit rods 204 on the left and right sides. Compression springs 208 are fixedly connected to the rear left and right sides of the safety doors 205. Closing components 206 are provided on the opposite sides of the two safety doors 205. A drive component 207 is provided on the rear side of the U-shaped plate 201. Rotation assembly Component 5 includes a rotating plate 501, the bottom of the outer wall of the rotating plate 501 being rotatably connected to the rear side of the platform plate 1. Each of the two adjacent rear ends of the two railing plates 4 is fixedly connected to a limiting block 502. The inner wall of the limiting block 502 is slidably connected to a locking post 503. The bottom of the outer wall of the two locking posts 503 respectively engages with the top left and right sides of the rotating plate 501. Pulling out the locking posts 503 allows them to engage with the rotating plate 501. Then, rotating the rotating plate 501 allows it to contact the corresponding floor, thus facilitating the removal of oversized items from above the platform plate 1. The limiting component 6 includes multiple limiting holes 601. The outer wall of 601 is opened on the top of the platform plate 1. The inner walls of multiple limiting holes 601 are threaded with threaded hooks 602. When moving large equipment, the threaded hooks 602 can be threaded into the limiting holes 601 at the corresponding positions to better limit the connection rope of the fixed equipment. The bottom of the platform plate 1 is fixedly connected with a cross reinforcement plate 603, which can improve the sturdiness of the platform plate 1. The closing component 206 includes two inclined grooves 2061. The outer walls of the two inclined grooves 2061 are respectively opened on the opposite side of the two hollow sliding plates 203. Inclined surfaces 2062 are opened on the left and right sides of the inner wall of the U-shaped plate 201.Under the action of the inclined groove 2061 and the inclined surface 2062, the safety door 205 is better engaged with the U-shaped plate 201. The drive component 207 includes a servo motor 2071. The front side of the servo motor 2071 is fixedly connected to the middle of the rear side of the hollow block 202. The output end of the servo motor 2071 passes through the rear side of the hollow block 202 and is fixedly connected to a gear 2072. The upper and lower sides of the outer wall of the gear 2072 are meshed with racks 2073. The opposite sides of the two racks 2073 are fixedly connected to the outer wall of the corresponding hollow slide plate 203. The servo motor 2071 can drive the gear 2072, thereby causing the racks 2073 to move, thereby realizing the linkage of the safety door 205.
[0042] Specifically, when using the platform, platform plate 1 serves as the basic structure of the entire hoisting platform, while the side railings 4 enhance the protection of the platform's sides. When the platform is hoisted to the required height, the locking column 503 can be pulled out, engaging with the rotating plate 501. The rotating plate 501 is then rotated to contact the corresponding floor, facilitating the removal of oversized items from above platform plate 1. When moving large equipment, threaded hooks 602 can be threaded into the corresponding limiting holes 601 to better limit the connection ropes securing the equipment. When personnel need to enter or exit platform plate 1, the servo motor 2071 in the drive assembly 207 is activated, which in turn drives the gear 2072 to rotate. The meshing relationship between gear 2072 and rack 2073 causes the hollow sliding plates 203 on both sides to move relative to or away from each other, thereby driving the safety door 205 to move together. When the inclined groove 2061 above the safety door 205 begins to contact the inclined surface 2062 above the U-shaped plate 201, the compression spring 208 pushes the safety door 205 to engage with the U-shaped plate 201 under the action of the inclined groove 2061 and the inclined surface 2062, thus completing the closing operation. To open, simply reverse the drive of the servo motor 2071 to reset the safety door 205 and open it, thereby achieving synchronous opening and closing of the safety door 205 and avoiding the risk of center of gravity shift when opening a single door.
[0043] Reference Figure 2 , Figure 3 and Figure 5The adjusting mechanism 3 includes multiple fixing rings 301, the bottoms of which are fixedly connected to the front and rear sides of the top of the two railing plates 4. Steel cables 302 are fixedly connected to the outer walls of the fixing rings 301. The fixing rings 301 and steel cables 302 allow the entire platform plate 1 to be lifted. A connecting rod 303 is provided at the top of the platform plate 1. T-shaped blocks 304 are slidably connected to the front and rear sides of the outer walls of the connecting rod 303. The T-shaped blocks 304 on both sides are moved to a position above the connecting rod 303. Then, through the fixing assembly 307, fixing bolts 3072 are passed through the corresponding limiting holes 3071 and fixed, thus completing the length fixation after adjustment. Rotating perforated plates 305 are rotatably connected to the left and right sides of the T-shaped blocks 304. The inner wall of the rotating perforated plates 305 engages with the outer wall of the top of the steel cables 302. 5. The rotation above the T-block 304 allows the T-block 304 to better adapt to platform plates 1 of different sizes. Connecting rings 306 are fixedly connected to the top left and right sides of the two T-blocks 304. The hook of the hoisting equipment is above the connecting rings 306, thereby hoisting the adjusted T-block 304 and connecting rod 303. The outer wall of the T-block 304 is provided with a fixing component 307. The fixing component 307 includes multiple limiting holes 3071. The outer walls of the multiple limiting holes 3071 are respectively opened on the left and right sides of the outer walls of the two T-blocks 304. The inner wall of the limiting hole 3071 is provided with a fixing bolt 3072. The outer wall of the fixing bolt 3072 penetrates the inner wall of the connecting rod 303 and engages with the inner wall of the corresponding limiting hole 3071. The fixing bolt 3072 is passed through the corresponding limiting hole 3071 and fixed, thereby completing the fixation of the adjusted length.
[0044] Specifically, when the platform panels 1 being hoisted are of the same size, the T-blocks 304 on both sides can be moved to a position above the connecting rod 303. Then, the fixing bolts 3072 are passed through the corresponding limiting holes 3071 and fixed through the fixing assembly 307, thereby fixing the adjusted length. The hoisting equipment hooks above the connecting ring 306, thereby hoisting the adjusted T-blocks 304 and connecting rod 303. The rotating perforated plate 305 above the T-blocks 304 allows the T-blocks 304 to better adapt to platform panels 1 of different sizes. Driven by the fixing ring 301 and the steel cable 302, the entire platform panel 1 can be hoisted, thus enabling the hoisting of platform panels 1 of different sizes.
[0045] Reference Figure 4 A limiting strip 7 is fixedly connected to the middle of the rear side of the inner wall of the hollow block 202. The left and right sides of the outer wall of the limiting strip 7 are slidably connected to the rear side of the corresponding hollow slide plate 203. When the hollow block 202 moves, it will move above the limiting strip 7. Under the restriction of the limiting strip 7, the entire hollow block 202 and the structure above it will move horizontally in a predetermined direction when moving.
[0046] Specifically, when the hollow block 202 moves, it will move above the limit bar 7. Under the restriction of the limit bar 7, the entire hollow block 202 and the structure above it will move horizontally in a predetermined direction, ensuring that the entire safety door 205 can move smoothly.
[0047] Working principle: First, when using this platform, the platform plate 1 serves as the basic structure of the entire hoisting platform, while the side railings 4 enhance the protection of the platform's sides. When the platform is hoisted to the required height, the locking column 503 can be pulled out, allowing it to engage with the rotating plate 501. The rotating plate 501 is then rotated to contact the corresponding floor, facilitating the removal of oversized items from above the platform plate 1. When moving large equipment, the threaded hooks 602 can be threaded into the corresponding limiting holes 601 to better limit the connection ropes securing the equipment. When personnel need to enter or exit the platform plate 1, simply activate the servo motor 2071 in the drive assembly 207, which in turn drives the gear 2072. The rotation, and the meshing relationship between the gear 2072 and the rack 2073, causes the hollow sliding plates 203 on both sides to move relative to or away from each other, thereby driving the safety door 205 to move together. When the inclined groove 2061 above the safety door 205 and the inclined surface 2062 above the U-shaped plate 201 begin to contact, under the push of the compression spring 208, the safety door 205 is locked above the U-shaped plate 201 by the action of the inclined groove 2061 and the inclined surface 2062, thus completing the closing operation. When opening, it is only necessary to reverse drive the servo motor 2071 to reset the safety door 205 and then open it, thereby realizing the synchronous opening and closing of the safety door 205 and avoiding the risk of center of gravity shift when opening a single door.
[0048] Furthermore, by adjusting the mechanism 3, when the size of the hoisted platform plates 1 is the same, the T-blocks 304 on both sides can be moved to a position above the connecting rod 303. Then, by using the fixing component 307, the fixing bolts 3072 are passed through the corresponding limiting holes 3071 and fixed, thereby completing the length fixation after adjustment. The hoisting equipment hooks above the connecting ring 306, thereby hoisting the adjusted T-blocks 304 and connecting rod 303. The rotation of the perforated plate 305 above the T-blocks 304 allows the T-blocks 304 to better adapt to platform plates 1 of different sizes. Driven by the fixing ring 301 and the steel cable 302, the entire platform plate 1 can be hoisted, thus enabling the hoisting of platform plates 1 of different sizes.
[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
