Description

Technical Field

[0001] This invention relates to the field of construction hoisting equipment technology, and in particular to a hoisting device for construction engineering. Background Technology

[0002] In construction, it is often necessary to hoist and transport materials such as pipes, cement, sand, gravel, and bricks to higher locations to reach the required height for installation by construction workers. Hoisting and lifting devices are typically used to efficiently and labor-savingly lift materials.

[0003] A search revealed a Chinese invention patent, CN118270671B, disclosing a safe hoisting and unloading device for construction engineering, relating to the field of construction hoisting equipment technology. The device includes a base, a rotating shaft sleeve, and a V-shaped load-bearing frame. A vertical support bracket is welded to the top of the base, and a rotating shaft sleeve is rotatably mounted through the center of the vertical support bracket. A brake disc is welded to the bottom of the rotating shaft sleeve. Two arc-shaped brake plates, horizontally sliding and repositioned by tension springs, are symmetrically installed inside the vertical support bracket. A U-shaped drive frame, sliding vertically up and down, is slidably mounted on the vertical support bracket. Two connecting rods symmetrically rotatably connect the horizontal side plates of the U-shaped drive frame to the two arc-shaped brake plates. Through the power transmission of a push rod and the two arc-shaped brake plates, the V-shaped load-bearing frame can convert its own swing inertial impact force into a clamping friction force that brakes its main body. This eliminates the need for an additional clamping drive motor for the auxiliary braking mechanism, contributing to overall weight reduction and cost reduction.

[0004] Existing fixed tower cranes are unable to meet the differentiated height requirements of different floors and complex structures. Conventional boom rotation mechanisms have blind spots and low positioning accuracy, which affects the efficiency of positioning complex structural components. Heavy prefabricated components require repeated adjustments to the center of gravity, and manual pushing is inefficient and poses safety hazards.

[0005] Therefore, the existing hoisting equipment used in construction projects cannot meet the needs of actual use, so there is an urgent need for improved technology to solve the above problems. Summary of the Invention

[0019] The present invention has the following beneficial effects:

[0020] 1. This invention utilizes a lifting structure mounted on a base plate. During use, a lifting drive structure and a steering structure are installed and positioned. The horizontal height of the hoisting structure is adjusted by the extension and retraction of the telescopic column. The lifting drive structure on the base plate drives and adjusts the elevation of the telescopic column during use. The self-locking performance between the worm gear and worm ensures the device remains stably at any adjustable height, preventing sudden drops due to unexpected forces. Simultaneously, the height adjustment function adapts to different construction scenarios, such as hoisting low-rise components and transferring materials to high-rise buildings, significantly improving the device's adaptability to different working heights. The steering structure on the lifting structure allows for horizontal rotation of the connecting structure during use, adjusting the horizontal angle of the hoisting structure and expanding the hoisting range from a "point" to a "fan-shaped area," covering a larger horizontal working radius, reducing the frequency of overall equipment movement, and improving adaptability to complex construction sites. The connecting structure on the steering structure allows for the installation and placement of the telescopic drive structure and the telescopic structure. The counterweight ensures stable placement of the device during hoisting, thus improving the device's stability during hoisting.

[0021] 2. This invention utilizes a telescopic drive structure mounted on the connecting structure to adjust the sliding direction and distance of the telescopic structure during use, thereby expanding the horizontal working area for hoisting. This allows it to adapt to the hoisting needs of materials of different sizes, such as long steel bars and large precast slabs, avoiding hoisting limitations caused by excessively long or wide materials. It enhances the device's adaptability to diverse construction materials. The telescopic structure on the connecting structure allows for the installation and placement of the moving structure during use, and the moving direction and distance of the moving structure are precisely adjusted and controlled via the moving adjustment gear. The moving structure on the telescopic structure also allows for the installation and placement of the moving drive structure and the winding structure, and the relative position of the hoisting structure is adjusted by the rotation of the moving gear. The fixed structure on the frame stabilizes the moving structure at the lower end of the inner cavity of the telescopic frame during use. The extension and retraction of the springs prevent displacement of the moving structure due to vibration or stress during hoisting operations. The springs also reduce hard friction between structures, extending the equipment's lifespan and enhancing overall stability. The moving drive structure on the moving structure drives the rotation of the moving gears, enabling left and right movement of the structure. This allows for precise positioning of the hoisting structure directly above the material, reducing manual adjustment time and avoiding secondary operations due to positioning deviations, significantly improving hoisting efficiency. The winding structure on the moving structure allows for fine-tuning of the hoisting structure's height through the rotation of the winding rollers. The smoothness of the winding gear and winding toothed belt drive prevents jamming or sudden drops during cable winding, ensuring controllability during the hoisting process. Precise height adjustment adapts to the height requirements of different stages such as material lifting, transfer, and placement, improving the accuracy of hoisting operations.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] Please see Figure 1-7As shown, this embodiment is a hoisting device for construction engineering, including a base plate 1.

[0035] The lifting structure 2 includes a limiting structure 21 fixedly connected to the middle of the upper end face of the base plate 1. A telescopic column 22 is slidably connected to the inner cavity of the limiting structure 21. A threaded groove 23 is opened in the middle of the lower end face of the telescopic column 22, and the threaded groove 23 penetrates the upper end face of the telescopic column 22. The limiting structure 21 includes a telescopic frame 211 fixedly connected to the middle of the upper end face of the base plate 1. A limiting plate 212 is fixedly connected to the lower part of the inner cavity of the telescopic frame 211. The telescopic column 22 is slidably connected to the inner cavity of the telescopic frame 211. A steering structure 4 is fixedly connected to the upper end face of the telescopic column 22. Through the lifting structure 2 on the base plate 1, the lifting drive structure 3 and the steering structure 4 are installed and placed, and the horizontal height of the hoisting structure is adjusted by the extension and retraction of the telescopic column 22.

[0036] Furthermore, the lifting drive structure 3 includes a worm gear 31 rotatably connected to the middle of the lower end face of the telescopic frame 211. A worm 32 is rotatably connected to one side of the worm gear 31 within the inner cavity of the telescopic frame 211. A lifting motor 33 is fixedly connected to the upper end face of the base plate 1, located on one side of the limiting structure 21. The rotating shaft of the front end face of the worm 32 passes through the telescopic frame 211 and is fixedly connected to the output end of the lifting motor 33. A threaded rod 34 is fixedly connected to the middle of the upper end face of the worm gear 31. The threaded rod 34 is threadedly connected to the inner cavity of the threaded groove 23. The limiting plate 2... Located above the worm gear 31, the worm gear 31 meshes with the worm 32. Through the lifting drive structure 3 on the base plate 1, the lifting of the telescopic column 22 is driven and adjusted during use. Furthermore, the self-locking performance between the worm gear 31 and the worm 32 allows the device to be stably maintained at any adjustable height, avoiding sudden drops due to accidental force. At the same time, the height adjustment function can adapt to the hoisting height requirements of different construction scenarios, such as hoisting low-rise components and transferring high-rise materials, greatly improving the adaptability of the device to different working heights.

[0037] Furthermore, the steering structure 4 includes a lower support plate 41 fixedly connected to the middle of the upper end face of the telescopic column 22. The outer edge of the upper end face of the lower support plate 41 is provided with an annular toothed groove 42. The upper end face of the lower support plate 41 is rotatably connected to an upper support plate 43 via a rotating shaft. The lower end face of the upper support plate 43 is symmetrically fixedly connected to a steering drive structure 44 with the rotating shaft as the center line. The steering drive structure 44 includes steering motors 441 symmetrically fixedly connected to the lower end face of the upper support plate 43. The output ends of the two steering motors 441 are fixedly connected to steering gears 442. The outer surface teeth of the steering gears 442 mesh with the annular toothed groove 42. The upper end face of the upper support plate 43 is fixedly connected to a connecting structure 5. Through the steering structure 4 on the lifting structure 2, the connecting structure 5 can be horizontally rotated during use. Then, by rotating, the horizontal angle of the hoisting structure 12 can be adjusted, so that the hoisting range can be expanded from a "point" to a "fan-shaped area", covering a larger horizontal working radius, reducing the frequency of overall equipment movement, and improving the adaptability to complex construction sites.

[0038] Furthermore, the connecting structure 5 includes a connecting frame 51 fixedly connected to the upper end face of the upper support plate 43. A counterweight 52 is fixedly connected to one side of the connecting frame 51. A connecting groove 53 is provided on the lower end face of the inner cavity of the connecting frame 51 away from the counterweight 52. A telescopic drive structure 6 is provided on the upper end face of the counterweight 52 and the side away from the connecting frame 51. A connecting groove is provided on the upper end face of the counterweight 52 to match the counterweight 52. A telescopic structure 7 is slidably connected to the inner cavity of the counterweight 52. Through the connecting structure 5 on the steering structure 4, the telescopic drive structure 6 and the telescopic structure 7 are installed and placed during use. Thus, the device can be stably placed during hoisting by the counterweight 52, thereby improving the stability of the device during hoisting.

[0039] Furthermore, the telescopic drive structure 6 includes a rotating frame 62 fixedly connected to the upper end face of the counterweight 52 located on one side of the connecting groove. A telescopic gear 61 is rotatably connected to the inner cavity of the rotating frame 62. A telescopic motor 63 is fixedly connected to the upper end face of the counterweight 52 located on one side of the rotating frame 62. The rotating shaft of the front end face of the telescopic gear 61 passes through the rotating frame 62 and is fixedly connected to the output end of the telescopic motor 63. Through the telescopic drive structure 6 on the connecting structure 5, the sliding direction and sliding distance of the telescopic structure 7 can be driven and adjusted during use, thereby expanding the horizontal working area for hoisting. Therefore, it can adapt to the hoisting needs of materials of different sizes, such as long steel bars and large precast slabs, avoiding the problem of hoisting restrictions caused by materials that are too long or too wide, and enhancing the adaptability of the device to diverse construction materials.

[0040] Furthermore, the telescopic structure 7 includes a second telescopic frame 71 slidably connected to the inner cavity of the connecting frame 51. The upper end face of the second telescopic frame 71 is evenly provided with telescopic adjustment grooves 72 that match the telescopic gears 61. The lower end face of the inner cavity of the second telescopic frame 71 is symmetrically and evenly provided with moving adjustment grooves 73. The lower end face of the second telescopic frame 71 is provided with a moving groove 74 located between the two moving adjustment grooves 73. The lower end face of the inner cavity of the second telescopic frame 71 is slidably connected to a moving structure 8. Through the telescopic structure 7 on the connecting structure 5, the moving structure 8 is installed and placed during use, and then the moving direction and moving distance of the moving structure 8 are precisely adjusted and controlled through the moving adjustment grooves 73.

[0041] Furthermore, the movable structure 8 includes a lower sliding plate 81 slidably connected to the middle of the lower end face of the inner cavity of the telescopic frame 71. A movable frame 82 is fixedly connected to the upper end face of the lower sliding plate 81. Movable gears 83 that match the movable adjustment grooves 73 are symmetrically rotatably connected to the front and rear end faces of the movable frame 82. An upper sliding plate 84 is fixedly connected to the upper end face of the movable frame 82. Through the movable structure 8 on the telescopic structure 7, the movable drive structure 10 and the winding structure 11 are installed and placed during use. Then, the relative position of the hoisting structure 12 is adjusted by the rotation of the movable gears 83.

[0042] Furthermore, the fixed structure 9 includes a telescopic sleeve 91 symmetrically fixedly connected to the middle of the upper end face of the upper sliding plate 84. A spring 92 is fixedly connected to the lower end face of the inner cavity of the telescopic sleeve 91, and a telescopic inner rod 93 is fixedly connected to the upper end face of the spring 92. The telescopic inner rod 93 is slidably connected to the inner cavity of the telescopic sleeve 91, and a fixed plate 94 is fixedly connected to the upper end face of the inner cavity of the telescopic frame 71. Through the fixed structure 9 on the moving structure 8, the moving structure 8 is stably placed on the lower end face of the inner cavity of the telescopic frame 71 during use. In addition, the extension and retraction of the spring 92 prevents the moving structure 8 from displacing due to vibration or force during hoisting operations. The buffering effect of the spring 92 reduces the hard friction between structures, extends the service life of the equipment, and further enhances the overall stability of the device.

[0043] Furthermore, the moving drive structure 10 includes a transmission rod 101 symmetrically rotatably connected to the inner cavity of the moving frame 82. A transmission gear 102 is fixedly connected to the middle of the outer surface of the transmission rod 101. A moving motor 105 is fixedly connected to one side of the middle of the lower end face of the upper sliding plate 84. A drive gear 104 is fixedly connected to the output end of the moving motor 105. A toothed belt 103 is connected between the transmission gear 102 and the drive gear 104. The rotating shafts on the front and rear end faces of the transmission rod 101 pass through the moving frame 82 and are fixedly connected to the moving gear 83. Through the moving drive structure 10 on the moving structure 8, the rotation of the moving gear 83 is driven during use, thus realizing the left and right movement of the moving structure 8. This enables the lifting structure 12 to be accurately positioned directly above the material, reducing the time cost of manual adjustment, avoiding secondary operations due to positioning deviations, and significantly improving the efficiency of lifting operations.

[0044] Furthermore, the winding structure 11 includes a winding roller 111 symmetrically rotatably connected to the inner cavity of the moving frame 82 and located within the inner cavity of the toothed belt 103. A winding gear 112 is fixedly connected to the rear part of the outer surface of the winding roller 111. A winding motor 114 is fixedly connected to the lower end face of the upper sliding plate 84 above the winding roller 111. Another winding gear 112 is fixedly connected to the output end of the winding motor 114. A winding toothed belt 113 is driven between the two winding gears 112. A winding cable is symmetrically driven to the outer surface of the winding roller 111. A lifting structure 12 is fixedly connected to the lower end of the winding cable. Through the winding structure 11 on the moving structure 8, the height of the lifting structure 12 can be finely adjusted by rotating the winding roller 111 during use, and then by rotating the winding gear 112... The smoothness of the winding toothed belt 113 transmission can avoid jamming or sudden drop when the cable is wound up, ensuring the controllability of the lifting process of the hoisting structure 12. At the same time, the precise height adjustment can adapt to the height requirements of different stages such as material lifting, transfer, and placement, improving the accuracy of hoisting operations.

[0045] Working principle: During operation, the base plate 1 is fixedly connected to the ground at a suitable position using fixing bolts.

[0046] When the conveying height needs to be adjusted, the lifting drive structure 3 is activated, causing the output end of the lifting motor 33 to rotate. This causes the worm gear 32 to rotate, which in turn causes the worm wheel 31, which meshes with the worm gear 32, to rotate. Consequently, the threaded rod 34 rotates, and the telescopic column 22 slides up and down under the limiting action of the telescopic frame 211. Therefore, the steering structure 4 and the connecting structure 5 rise and fall.

[0047] When the horizontal angle of the hoisting needs to be adjusted, the steering structure 4 is activated, causing the output end of the steering motor 441 to rotate. This causes the steering gear 442 to rotate, and since the steering gear 442 meshes with the annular tooth groove 42, it pushes the upper support plate 43, thus achieving the horizontal rotation of the connecting structure 5.

[0048] When the hoisting area needs to be adjusted, the telescopic drive structure 6 is activated, causing the output end of the telescopic motor 63 to rotate. This causes the telescopic gear 61 to rotate. At this time, because the telescopic adjustment groove 72 meshes with the telescopic gear 61, the telescopic frame 71 slides to the right, thereby increasing the horizontal hoisting area.

[0049] When adjusting the hoisting position, the moving drive structure 10 is activated, causing the output end of the moving motor 105 to rotate. This drives the gear 104 to rotate, which in turn causes the toothed belt 103 to rotate. Consequently, the transmission gear 102 rotates, further causing the transmission rod 101 to rotate. Since the moving gear 83 is fixedly connected to the transmission rod 101, the lower sliding plate 81 moves under the action of the moving gear 83 and the moving adjustment groove 73. This positions the moving structure 8 and the hoisting structure 12 above the hoisted material.

[0050] Simultaneously, due to the extension and retraction of spring 92, the fixed plate 94 and the upper end face of the inner cavity of telescopic frame 71 are in contact with each other. Therefore, through the extension and retraction of the fixed structure 9, the movable structure 8 is stably placed on the lower end face of the inner cavity of telescopic frame 71.

[0051] When hoisting is required, the winding structure 11 is activated, causing the output end of the winding motor 114 to rotate. Consequently, the winding gear 112 at the output end of the winding motor 114 rotates, which in turn causes the winding toothed belt 113 to rotate. This further causes the winding roller 111 and the winding gear 112 on the outer surface of the winding roller 111 to rotate, thereby causing the winding cable to wrap around the outer surface of the winding roller 111. This allows for adjustment of the relative height of the hoisting structure 12, and the material to be hoisted can then be hooked and hoisted using the hoisting structure 12.
