Description

Technical Field

[0001] This utility model is a construction safety platform for building engineering, belonging to the field of building engineering. Background Technology

[0002] In construction engineering, a safe construction platform is a key facility for ensuring the safety and efficiency of high-altitude operations. Rotary lifting equipment, as an important type, allows for flexible adjustment of the hook position to meet material lifting needs through the coordinated operation of the boom and trolley. The boom adopts an I-beam structure design, with rollers on the trolley overlapping the horizontal section at the lower end of the boom. The position of the trolley is adjusted by the rolling of the rollers along this horizontal section. However, in actual operation, after the trolley lifts the building material, the reaction force generated by the material acts directly on the contact area between the rollers and the boom, causing wear and tear due to repeated stress. This wear not only shortens the service life of the boom but also reduces the overall safety of the equipment as the boom thins, creating potential hazards for high-altitude operations. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a safe construction platform for building engineering to solve the problems mentioned in the background technology. This utility model can protect the boom and improve the overall safety.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a construction safety platform, comprising a column, a boom rotatably mounted on the upper end of the column, the boom having an "I"-shaped cross-section, a drive component for driving the boom to rotate mounted on the upper end of the column, a U-shaped frame on the lower side of the boom, multiple evenly arranged rollers mounted on two parallel sides of the U-shaped frame, multiple end-to-end guard plates on two parallel inner sides of the boom, the guard plates having a "U"-shaped structure, the horizontal portion of the lower end of the guard plate fitting against the upper surface of the horizontal portion of the lower end of the boom, the rollers rolling in contact with the horizontal portion of the lower end of the guard plate, the guard plate being connected to the boom via a connector, and a lifting component mounted at the bottom of the U-shaped frame.

[0005] Furthermore, the driving component includes a first motor, and two ear plates arranged vertically and fixedly connected to the column are sleeved on the upper end of the column. The first motor is installed on the lower surface of the upper ear plate. A column body is provided on the side of the column away from the first motor. One end of the boom is fixedly connected to the column body. The column body is rotatably installed between the two ear plates. A large sprocket is installed on the upper end of the column body. The output shaft of the first motor extends to the upper side of the upper ear plate and is equipped with a small sprocket. The small sprocket is connected to the large sprocket through a chain.

[0006] Furthermore, the upper side of the boom is provided with an inclined pull arm, one end of which is installed on the upper end of the column, and the end of the pull arm away from the column is connected and fixed to the end of the boom away from the column. Multiple reinforcing ribs are installed at equal intervals on the upper surface of the boom, and the upper ends of the reinforcing ribs are connected and fixed to the pull arm.

[0007] Furthermore, the connector includes screws, and the upper horizontal part of the guard plate is evenly provided with a plurality of lower small holes, and the upper horizontal part of the boom is provided with a plurality of upper small holes aligned with the lower small holes. Screws are inserted into the channel formed by the lower small holes and the upper small holes, and one end of the screw extends to the upper side of the boom and is threaded with a nut.

[0008] Furthermore, a horizontal strip is provided on the lower side of the horizontal part at the upper end of the guard plate. The horizontal strip is connected and fixed to the guard plate. Multiple round holes aligned with the lower small holes are evenly opened on the upper surface of the horizontal strip. Multiple connecting ribs are installed at equal intervals on the upper surface of the horizontal strip. The connecting ribs and round holes are arranged alternately. The screw passes through the round holes, the lower small holes and the upper small holes. There is a gap between the horizontal strip and the horizontal part at the upper end of the guard plate.

[0009] Furthermore, the vertical portion of the guard plate has an elongated oval opening, which is arranged along the length of the guard plate.

[0010] Furthermore, the lifting device includes a frame, with the frame mounted at the bottom of the U-shaped frame. A rope reel is rotatably mounted on one side of the frame, with a steel wire rope wound on the rope reel and a hook suspended from the steel wire rope. A worm wheel is mounted on one end of the rope reel, and a worm gear meshing with the worm wheel is provided on the lower side of the worm wheel. A second motor is mounted on the frame, and the output shaft of the second motor is connected to one end of the worm gear by bolts.

[0011] Furthermore, a base plate is installed at the bottom of the column, and multiple fixing holes are evenly opened on the upper surface of the base plate. Multiple triangular ribs are installed in a ring at equal intervals on the upper surface of the base plate, and the triangular ribs are connected and fixed to the column.

[0012] The beneficial effects of this utility model are:

[0013] 1. Multiple U-shaped guard plates are installed on the inner side of the boom, with their lower horizontal parts fitting against the lower horizontal part of the boom. This allows the rollers to roll and contact the guard plates, isolating the boom from the rollers and preventing the material reaction force from acting directly on the boom. The guard plates can independently bear wear, extending the service life of the boom. Because the boom is prevented from being worn thin, the overall safety is improved.

[0014] 2. Multiple end-to-end guard plates facilitate the replacement of worn guard plates, while unworn guard plates do not need to be replaced. At the same time, when replacing guard plates, the U-shaped frame can be moved to other areas, so that the guard plates can be replaced without separating the U-shaped frame and the boom.

[0015] 3. When using screws and nuts to restrict the relative position of the guard plate and the boom, make sure one end of the screw passes through the channel formed by the round hole, the lower small hole and the upper small hole before screwing on the nut. This facilitates the assembly and disassembly of the guard plate and the boom. At the same time, under the combined action of the horizontal strip and the connecting rib, there is a gap between the screw head and the horizontal part of the upper end of the guard plate. When the screw and nut cannot be separated smoothly, the screw can be cut off by using the gap between the horizontal strip and the horizontal part of the upper end of the guard plate.

Detailed Implementation

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

[0024] Please see Figure 1This utility model provides a technical solution: a construction safety platform for building engineering, including a column 1, a base plate installed at the bottom of the column 1, a plurality of fixing holes evenly opened on the upper surface of the base plate, and a plurality of triangular ribs installed in a ring at equal intervals on the upper surface of the base plate, the triangular ribs being connected and fixed to the column 1, the triangular ribs improving the mechanical strength of the connection between the base plate and the column 1, and installing the base plate at the required position to complete the restriction of the position of the column 1.

[0025] See Figures 1-3 A boom 9 is rotatably mounted on the upper end of the column 1. The boom 9 has an "I" shaped cross-section. Two ear plates 2 are arranged vertically and fixed to the upper end of the column 1. A first motor 4 is mounted on the lower surface of the upper ear plate 2. A column body 3 is provided on the side of the column 1 away from the first motor 4. One end of the boom 9 is fixed to the column body 3. The column body 3 is rotatably mounted between the two ear plates 2. A large sprocket 7 is mounted on the upper end of the column 3. The output shaft of the first motor 4 extends to the upper side of the upper ear plate 2 and is equipped with a small sprocket 5. The small sprocket 5 is connected to the large sprocket 7 through a chain 6. When the first motor 4 is working, it drives the boom 9 to rotate within a range of less than 360° through the transmission of the small sprocket 5, the large sprocket 7 and the chain 6.

[0026] See Figure 1 and Figure 5 The boom 9 has an inclined tie arm 8 on its upper side. One end of the tie arm 8 is installed on the upper end of the column 3. The end of the tie arm 8 away from the column 3 is connected and fixed to the end of the boom 9 away from the column 3. Multiple reinforcing ribs 10 are installed at equal intervals on the upper surface of the boom 9. The upper end of the reinforcing ribs 10 is connected and fixed to the tie arm 8. The design of the tie arm 8 and the reinforcing ribs 10 improves the bending resistance of the boom 9. The boom 9 has a U-shaped frame 11 on its lower side. Multiple evenly arranged rollers 26 are installed on two parallel sides inside the U-shaped frame 11. A frame 12 is installed at the bottom of the U-shaped frame 11. A rope reel 23 is mounted on one side, with a steel wire rope 14 wound on it. A hook 15 is suspended from the steel wire rope 14. A worm wheel 24 is installed at one end of the rope reel 23, and a worm 25 meshing with the worm wheel 24 is provided on the lower side of the worm wheel 24. A second motor 13 is installed on the frame 12. The output shaft of the second motor 13 is connected to one end of the worm 25 by bolts. When the second motor 13 is working, it drives the rope reel 23 to rotate through the transmission of the worm wheel 24 and the worm 25, so that the steel wire rope 14 is lowered or wound on the rope reel 23. At this time, the height of the hook 15 changes.

[0027] See Figures 1-5The two parallel inner sides of the boom 9 are each provided with multiple end-to-end guard plates 16. The guard plates 16 have a "U"-shaped structure. The vertical part of the guard plate 16 has an elongated oval opening 21, which is arranged along the length of the guard plate 16. The elongated oval opening 21 reduces the material cost of the guard plate 16. The horizontal part of the lower end of the guard plate 16 is in contact with the upper surface of the horizontal part of the lower end of the boom 9. The roller 26 makes rolling contact with the horizontal part of the lower end of the guard plate 16. The horizontal part of the upper end of the guard plate 16 has multiple small lower holes evenly distributed. The horizontal part of the upper end of the boom 9 has multiple small upper holes aligned with the small lower holes. Screws 18 are inserted into the channel formed by the small lower holes and the small upper holes. One end of the screw 18 extends to the upper side of the boom 9 and is threaded. With nuts 19, multiple U-shaped guard plates 16 are installed on the inner side of the boom 9, with their lower horizontal parts fitting against the lower horizontal part of the boom 9, so that the rollers 26 roll in contact with the guard plates 16, isolating the boom 9 from the rollers 26 and preventing the material reaction force from acting directly on the boom 9. The guard plates 16 can independently bear wear, extending the service life of the boom 9. Because the boom 9 is prevented from being worn thin, the overall safety is improved. Multiple guard plates 16 make it easy to replace worn guard plates 16, while unworn guard plates 16 do not need to be replaced. At the same time, when replacing guard plates 16, the U-shaped frame 11 is moved to other areas, so that the guard plates 16 can be replaced without separating the U-shaped frame 11 and the boom 9.

[0028] See Figure 1 , Figure 2 and Figure 4 A horizontal strip 20 is provided on the lower side of the horizontal part at the upper end of the guard plate 16. The horizontal strip 20 is connected and fixed to the guard plate 16. A plurality of round holes aligned with the lower small holes are evenly opened on the upper surface of the horizontal strip 20. A plurality of connecting ribs 22 are installed at equal intervals on the upper surface of the horizontal strip 20. The connecting ribs 22 and the round holes are arranged alternately. Screws 18 pass through the round holes, the lower small holes and the upper small holes. There is a gap between the horizontal strip 20 and the horizontal part at the upper end of the guard plate 16. The guard plate is restrained by fasteners formed by screws 18 and nuts 19. When the relative positions of the guard plate 16 and the boom 9 are such that one end of the screw 18 passes through the channel formed by the round hole, the lower small hole and the upper small hole, and then the nut 19 is screwed on, thus facilitating the disassembly and assembly of the guard plate 16 and the boom 9. At the same time, under the combined action of the horizontal strip 20 and the connecting rib 22, there is a gap between the head of the screw 18 and the horizontal part of the upper end of the guard plate 16. When the screw 18 and the nut 19 cannot be separated smoothly, the screw 18 can be cut off by using the gap between the horizontal strip 20 and the horizontal part of the upper end of the guard plate 16.
