Description

Technical Field

[0001] This invention relates to the field of construction lifting equipment technology, specifically to a type of lifting equipment used in construction engineering. Background Technology

[0002] Building materials are the various materials used in construction projects. There are many types of building materials, broadly categorized as: inorganic materials, including metallic materials (ferrous and non-ferrous metals) and non-metallic materials, such as natural stone, calcined clay products, cement, concrete, and silicate products. However, these building materials are typically heavy, making them difficult to move manually or with equipment.

[0003] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. Common double-girder bridge cranes are used on construction sites to effectively lift building materials. However, existing double-girder bridge cranes have unstable structures, require high power, and the steel cables are prone to rolling when lifting building materials, which can easily lead to deviation and pose a significant danger. Furthermore, the existing hooks are mostly fixed in direction, making it difficult to achieve self-rotation. The position of the building materials needs to be adjusted before they can be lifted. When the building materials are at a high position, workers cannot reach them, and it is difficult to adjust the hook angle, making it inconvenient to use. Therefore, it is necessary to propose a lifting device for construction engineering and its working method. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a lifting device for construction engineering and its working method, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lifting device for construction engineering, comprising a crossbeam plate, main supports inclinedly arranged on the four sides of the lower side of the crossbeam plate, two base plates located below the main supports, a sliding groove provided on the lower side of the crossbeam plate, and multiple auxiliary support feet inclinedly arranged between the upper sides of the two base plates and the crossbeam plate, each auxiliary support foot being located on both sides of the main supports, a winding roller mounted on the upper side of one of the base plates, a winding motor mounted on one side of the winding roller, and a slidably adjustable hanging device provided on the lower side of the crossbeam plate. A first driven roller is installed on one side of the lower side of the crossbeam plate. The first driven roller is horizontally positioned on one side of the suspension device. A take-up roller winds up a steel rope. A second driven roller is rotatably connected to the middle of the suspension device. The steel rope is pulled from the first driven roller to the second driven roller in the middle of the suspension device. A hook is fixedly installed at the end of the steel rope. The hook hangs below the suspension device. Multiple auxiliary support feet are inclined between the crossbeam plate and the base plate to enhance the stability of the crossbeam plate. The steel rope is wound up by the take-up roller, and the steel rope is connected to the first driven roller and the second driven roller respectively. In this way, the friction is small when the take-up roller winds up, and the winding and lifting efficiency is high.

[0006] A further improvement is made to the hanging device, which includes a connecting slider, a screw, a drive motor, a limiting rod, a connecting frame, and an I-beam rotating shaft. The connecting slider is slidably mounted on a groove, and the screw and limiting rod are horizontally installed inside the groove, passing through the connecting slider. The screw is rotatably connected to the crossbeam plate and threadedly connected to the connecting slider. The drive motor is installed on one side of the crossbeam plate and connected to the screw shaft. The connecting frame is an integral structure with the connecting slider and is located below the connecting slider. The I-beam rotating shaft is rotatably mounted below the connecting frame. The rotation of the screw can drive the connecting slider to move left and right. The screw transmission has high precision and a more stable transmission effect. The bottom of the connecting slider has an integral connecting frame, which can move left and right. Therefore, the building objects hung by the hook can be moved left and right, making it flexible and convenient to use.

[0007] A further improvement is made: two electric push rods are vertically mounted on the lower side of the I-shaped rotating shaft. The telescopic ends of the electric push rods are connected to a perforated plate. Several triangular clamping pieces arranged in a circular array are interspersed in the middle of the perforated plate. The top of each triangular clamping piece is hinged to the lower side of the connecting frame. The outer edge of each triangular clamping piece is narrower at the top and wider at the bottom. The outer edge of each triangular clamping piece is close to the perforated part in the middle of the perforated plate. The inner edge of each triangular clamping piece is fitted with anti-slip rubber. When the electric push rod extends downward, the inner circular perforation can push each triangular clamping piece to tighten towards the steel rope when the perforated plate moves downward, so that the anti-slip rubber of each triangular clamping piece can hold the steel rope tightly, improving its stability.

[0008] A further improvement is that the steel rope, after being pulled by the second driven roller, passes through the H-shaped rotating shaft and the middle of the hollow plate respectively. The steel rope is located between each of the triangular clamping plates. The second driven roller has the same structure as the first driven roller, and the first driven roller has a limiting groove in the middle. The limiting groove is recessed inward to effectively prevent the steel rope from running off track.

[0009] A further improvement is that an external gear is fitted around the bottom outer ring of the I-shaped rotating shaft, a rotary motor is installed on one side of the connecting frame, the shaft of the rotary motor is connected to a rotary gear, and the rotary gear meshes with the external gear for transmission.

[0010] A further improvement is that several ball bearings are embedded and installed on the upper surface of the I-beam rotating shaft, and are connected to the connecting frame through the ball bearings. The rotating motor drives the rotating gear to rotate, and the rotating gear meshes with the external gear on the outer ring of the I-beam rotating shaft, causing the I-beam rotating shaft to rotate. Since each triangular clamping piece is installed on the lower side of the I-beam rotating shaft, the triangular clamping pieces can be rotated and adjusted as needed when clamping the steel rope, so that the steel rope rotates to the required direction, making it simpler and more convenient to use.

[0011] It also provides a working method for a lifting device used in construction engineering and its working method:

[0012] This invention features multiple auxiliary support feet inclined between the crossbeam and the base plate to enhance the stability of the crossbeam. A steel rope extends from the take-up roller and connects sequentially to the first and second driven rollers. This design minimizes friction during take-up and increases lifting efficiency. The steel rope is positioned in a limiting groove to effectively prevent misalignment. A take-up motor drives the take-up roller to wind and unwind the steel rope, allowing the hook to move up and down below the suspension device. Because the triangular clamping plates are narrower at the top and wider at the bottom, they extend downwards via an electric push rod. As the perforated plate moves downwards, the inner circular perforations push the triangular clamping plates towards the steel rope, ensuring the anti-slip rubber of each clamping plate grips the rope tightly and improves stability. Furthermore, the rotary motor drives the rotary gear to rotate, and the rotary gear meshes with the external gear on the outer ring of the I-beam rotating shaft, causing the I-beam rotating shaft to rotate. Since each triangular clamping piece is installed on the lower side of the I-beam rotating shaft, the triangular clamping pieces can be rotated and adjusted as needed when clamping the steel rope, so that the steel rope rotates to the required direction. Moreover, the I-beam rotating shafts are connected to the connecting frame through ball bearings, which can reduce the friction of the rotating shafts. The connecting slider moves left and right through the set screw thread transmission. The screw transmission has high precision and more stable transmission effect. The integrated connecting frame on the lower side of the connecting slider can therefore move left and right, so the construction objects suspended by the hook can be moved left and right, making it flexible and convenient to use.

[0013] By adopting the above technical solution, the beneficial effects of the present invention are:

[0014] The present invention has a safe and stable structure, low power consumption, and wide applicability. Multiple auxiliary support feet are inclined between the crossbeam plate and the bottom plate to enhance the stability of the crossbeam plate. The steel rope is wound up by a winding roller, and the steel rope is connected to the first driven roller and the second driven roller respectively. In this way, the friction of the winding roller is small when winding up, and the winding and lifting efficiency is high.

[0015] The suspended device can move left and right and can effectively clamp the steel rope to prevent it from rolling, making it more stable. After clamping, it can rotate the steel rope, so that the hook can rotate actively and adjust the direction of the hook accordingly. It can also drive the suspended building materials to rotate to a certain extent. It is easy to use and has a wide range of applications. Compared with the prior art, this invention has more prominent substantive features and significant progress. Attached Figure Description

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-5As shown in the figure, the present invention provides a technical solution for a lifting device used in construction engineering: its structure includes a crossbeam plate 1, main supports 2 inclinedly arranged on the four sides of the lower side of the crossbeam plate 1, two base plates 3 arranged on the lower side of the main supports 2, a sliding groove 101 provided on the lower side of the crossbeam plate 1, and a plurality of auxiliary support feet 5 inclinedly arranged between the upper side of the two base plates 3 and the crossbeam plate 1, each of the auxiliary support feet 5 being respectively arranged on both sides of the main supports 2, a winding roller 6 installed on the upper side of one of the base plates 3, a winding motor 61 installed on one side of the winding roller 6, a slidably adjustable hanging device 7 provided on the lower side of the crossbeam plate 1, and a first driven roller installed on one side of the lower side of the crossbeam plate 1. The first driven roller 8 is horizontally positioned on one side of the suspension device 7. The take-up roller 6 winds up a steel rope 9. A second driven roller 81 is rotatably connected to the middle of the suspension device 7. The steel rope 9 is pulled from the first driven roller 8 to the second driven roller 81 in the middle of the suspension device 7. A hook 10 is fixedly installed at the end of the steel rope 9. The hook 10 hangs below the suspension device 7. Multiple auxiliary support feet 5 are inclined between the crossbeam plate 1 and the base plate 3 to enhance the stability of the crossbeam plate 1. The steel rope 9 is wound up by the take-up roller 6, and the steel rope 9 is connected to the first driven roller 8 and the second driven roller 81 respectively. In this way, the take-up roller 6 has low friction when winding and high winding and lifting efficiency. The suspension device 7 includes a connecting slider 71 and a screw. The system comprises a screw rod 711, a drive motor 712, a limiting rod 713, a connecting frame 72, and an I-beam rotating shaft 73. The connecting slider 71 is slidably mounted on a slide groove 101. Both the screw rod 711 and the limiting rod 713 are horizontally mounted inside the slide groove 101, passing through the connecting slider 71. The screw rod 711 is rotatably connected to the crossbeam plate 1 and threadedly connected to the connecting slider 71. The drive motor 712 is mounted on one side of the crossbeam plate 1 and shaft-connected to the screw rod 711. The connecting frame 72 is an integral structure with the connecting slider 71 and is located below the connecting slider 71. The I-beam rotating shaft 73 is rotatably mounted below the connecting frame 72. Rotation of the screw rod 711 drives the connecting slider 71 to move left and right. With high precision and more stable transmission, the connecting slider 71 has an integrated connecting frame 72 at its bottom, allowing the connecting frame 72 to move left and right. This enables the hanging construction objects from the hook 10 to shift left and right, making it flexible and convenient to use. Two electric push rods 74 are vertically mounted on the lower side of the I-beam rotating shaft 73. The telescopic ends of the electric push rods 74 are connected to a perforated plate 75. Several circularly arranged triangular clamping pieces 76 are interspersed in the center of the perforated plate 75. The top of each triangular clamping piece 76 is hinged to the lower side of the connecting frame 72. The outer edges of each triangular clamping piece 76 are narrower at the top and wider at the bottom, and the outer edges of each triangular clamping piece 76 are close to the perforated portion in the center of the perforated plate 75. Anti-slip rubber 761 is fitted to the inner edges of each triangular clamping piece 76.As the electric push rod 74 extends downwards, the inner circular hollow section of the perforated plate 75 pushes each triangular clamping piece 76 to tighten towards the steel rope 9 when it moves downwards. This allows the anti-slip rubber 761 of each triangular clamping piece 76 to grip the steel rope 9, improving its stability. The steel rope 9, after being pulled by the second driven roller 81, passes through the H-shaped rotating shaft 73 and the middle of the perforated plate 75. The steel rope 9 is positioned between each of the triangular clamping pieces 76. The second driven roller 81 has the same structure as the first driven roller 8, and the first driven roller 8 has a limiting groove 82 in the middle. The limiting groove 82 is recessed inwards to effectively prevent the steel rope 9 from shifting. An external gear 731 is fitted around the bottom outer ring of the H-shaped rotating shaft 73. The connecting frame 72... A rotary motor 721 is installed on one side, and a rotary gear 722 is connected to the shaft of the rotary motor 721. The rotary gear 722 meshes with an external gear 731 for transmission. Several ball bearings 732 are embedded in the upper surface of the H-shaped rotating shaft 73 and connected to the connecting frame 72 through the ball bearings 732. The rotary motor 721 drives the rotary gear 722 to rotate, and the rotary gear 722 meshes with the external gear 731 on the outer ring of the H-shaped rotating shaft 73, causing the H-shaped rotating shaft 73 to rotate. Since each triangular clamping piece 76 is installed on the lower side of the H-shaped rotating shaft 73, the triangular clamping pieces 76 can be rotated and adjusted as needed when clamping the steel rope 9, allowing the steel rope 9 to rotate to the required direction, making it simpler and more convenient to use.

[0025] Working Principle: This invention provides a working method for a lifting device used in construction engineering. Multiple auxiliary support feet 5 are inclined between the crossbeam plate 1 and the base plate 3 to enhance the stability of the crossbeam plate 1. A steel rope 9 extends from the winding roller 6 and is sequentially connected to the first driven roller 8 and the second driven roller 81. This reduces friction during winding and increases lifting efficiency. The steel rope 9 is positioned on the limiting groove 82 to effectively prevent displacement. The winding motor 61 drives the winding roller 6 to wind and unwind the steel rope 9, allowing the hook 10 to move up and down below the hanging device 7. Because the triangular clamping plates 76 are narrower at the top and wider at the bottom, they extend downwards via an electric push rod 74. When the perforated plate 75 moves downwards, the inner circular perforation pushes the triangular clamping plates 76 to tighten towards the steel rope 9, ensuring that the anti-slip rubber 761 of each triangular clamping plate 76 grips the steel rope tightly. The rope 9 enhances its stability, and the rotating motor 721 drives the rotating gear 722 to rotate. The rotating gear 722 meshes with the external gear 731 on the outer ring of the I-beam rotating shaft 73, causing the I-beam rotating shaft 73 to rotate. Since each triangular clamping piece 76 is installed on the lower side of the I-beam rotating shaft 73, the triangular clamping pieces 76 can be rotated and adjusted as needed when clamping the steel rope 9, so that the steel rope 9 rotates to the required direction. The I-beam rotating shaft 73 is connected to the connecting frame 72 through the ball bearings 732, which reduces the friction of the rotation of the I-beam rotating shaft 73. The connecting slider 71 moves left and right through the threaded transmission of the screw 711. The screw transmission has high precision and more stable transmission effect. The integrated connecting frame 72 on the lower side of the connecting slider 71 can therefore move left and right. Therefore, the building objects suspended by the hook 10 can move left and right, making it flexible and convenient to use.
