Description

Technical Field

[0001] This utility model relates to the technical field of construction lifting platforms, specifically a construction lifting platform for a steel platform inside a power plant chimney. Background Technology

[0002] Power plant chimneys typically consist of a steel inner cylinder for exhausting flue gas within a concrete shell. The steel inner cylinder is much thinner and longer than the outer shell, making it prone to swaying even with the outer shell providing wind protection. Therefore, for chimneys with steel inner cylinders, a series of steel platforms, including suspended platforms and anti-sway platforms, must be installed inside the chimney. To facilitate construction on the steel platforms, corresponding construction lifting platforms are often used.

[0003] However, current steel platform construction lifting platforms inside power plant chimneys are often used as lifting devices due to the limited space inside the chimney. When lifting construction materials or supplies, the weight of the materials or supplies may cause the lifting device to tip over, which can easily lead to construction accidents. In order to address the above problems, a new steel platform construction lifting platform for power plant chimneys is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a construction lifting platform for a steel platform inside a power plant chimney, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A construction lifting platform for a steel platform inside a power plant chimney includes a column. A base is fixedly connected to the bottom of the column. Two base plates are symmetrically fixedly connected to the side wall of the base. Support rods are symmetrically rotatably connected to the side wall of the column via pins. Supports are hinged to the bottom ends of the support rods. The base, base plates, and supports are fixedly connected to the steel platform inside the chimney by bolts. A support plate is fixedly installed on the top of the column. An installation plate is provided on the top of the support plate. A rotating arm is fixedly connected to the top of the installation plate. A take-up roller is provided on one side of the top of the installation plate. A first motor for driving the take-up roller to rotate is installed on the take-up roller. A traction rope is wound around the take-up roller. A steering pulley is rotatably connected to the end of the rotating arm. The traction rope passes around the steering pulley and has a hook installed at the end of the traction rope.

[0007] As a further embodiment of this utility model: the included angle between the base plate and the adjacent support rod is 90°, and the included angle between the base plates and the support rods is 90°.

[0008] As a further embodiment of this utility model: a slewing bearing is provided between the support plate and the mounting plate. The fixed end of the slewing bearing is fixedly connected to the support plate by bolts, and the rotating end of the slewing bearing is fixedly connected to the mounting plate by bolts. A second motor is fixedly installed at the bottom of the support plate. A gear is fixedly installed inside the slewing bearing through the support plate at the output end of the second motor. The gear meshes with the internal teeth of the rotating end of the slewing bearing.

[0009] As a further improvement of this utility model, a rotating handle is fixedly installed at the end of the support plate.

[0010] As a further improvement of this utility model, reinforcing plates are uniformly fixedly installed between the bottom of the support plate and the column.

[0011] As a further improvement of this utility model: a connecting bracket is fixedly installed at the bottom end of the rotary arm, and a guide sleeve is fixedly connected to the end of the connecting bracket, with the guide sleeve fitted onto the traction rope.

[0012] As a further embodiment of this utility model: multiple guide components are uniformly and fixedly installed on the top of the rotary arm. The guide components include two L-shaped supports, which are fixedly installed on the rotary arm. Two guide wheels are symmetrically rotatably connected inside the L-shaped supports, and the traction rope passes between the two guide wheels.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When lifting materials, the symmetrically fixed base plates on both sides of the base increase the support of the base, and the support rods support and pull the column, which greatly improves the stability of the device.

[0015] 2. In this utility model, when the traction rope is being lifted, it is pulled and reciprocates. The traction rope moves under the guidance of two guide wheels of the guide assembly between the take-up roller and the steering pulley. In the vertical direction, it is limited by the guide sleeve fixedly connected to the end of the connecting bracket, which reduces the risk of the traction rope disengaging from the steering pulley and increases the stability of the traction rope during use.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] Please see Figures 1-4 In this embodiment of the utility model, a construction lifting platform for a steel platform inside a power plant chimney includes a column 1. A base 2 is fixedly connected to the bottom of the column 1. Two base plates 3 are symmetrically fixedly connected to the side walls of the base 2. Support rods 4 are symmetrically rotatably connected to the side walls of the column 1 via pins. A support 5 is hinged to the bottom end of the support rod 4. The base 2, base plates 3, and support 5 are fixedly connected to the steel platform inside the chimney by bolts. A support plate 6 is fixedly installed on the top of the column 1. An installation plate 8 is provided on the top of the support plate 6. A rotating arm 9 is fixedly connected to the top of the installation plate 8. A take-up roller 10 is provided on one side of the top of the installation plate 8. A first motor 11 for driving the take-up roller 10 to rotate is installed on the take-up roller 10. A traction rope 14 is wound around the take-up roller 10. A steering pulley 19 is rotatably connected to the end of the rotating arm 9. The traction rope 14 passes around the steering pulley 19. A hook 15 is installed at the end of the traction rope 14. The hook 15 is a hook to prevent falling off. A remote control for remote control is provided outside the device.

[0023] In use, the device is placed in the lifting position of the steel platform inside the chimney. The base 2 and the base plate 3 are fixed to the internal steel platform with bolts. At the same time, the support rod 4 is rotatably connected to the side wall of the column 1 through a pin. The support 5 rotatably connected to the end of the support rod 4 is fixedly installed on the steel platform inside the chimney with bolts. After the material to be lifted is hung on the hook 15, the output end of the first motor 11 drives the winding roller 10 to rotate. The winding roller 10 winds up the traction rope 14, lifting the material hung on the hook 15 to the internal steel platform. When lifting the material, the base plates 3 symmetrically fixed to both sides of the base 2 increase the support of the base 2, and the support rod 4 supports and pulls the column 1, which greatly improves the stability of the device.

[0024] The angle between the base plate 3 and the adjacent support rod 4 is 90°, and the angle between the base plates 3 and the support rods 4 is also 90°. By distributing the support rods 4 and the base plate 3 relatively evenly, the support for the column 1 is made more stable, increasing the stability of the device during use.

[0025] A slewing bearing 7 is provided between the support plate 6 and the mounting plate 8. The fixed end of the slewing bearing 7 is fixedly connected to the support plate 6 by bolts, and the rotating end of the slewing bearing 7 is fixedly connected to the mounting plate 8 by bolts. A second motor 13 is fixedly installed at the bottom of the support plate 6. The second motor 13 is a motor with a brake. The output end of the second motor 13 passes through the support plate 6 and a gear 20 is fixedly installed inside the slewing bearing 7. The gear 20 meshes with the internal teeth of the rotating end of the slewing bearing 7. In use, the output end of the second motor 13 drives the gear 20 to rotate, and the rotating gear 20 drives the rotating end of the slewing bearing 7 to rotate. The rotating end then drives the slewing arm 9 to rotate through the mounting plate 8, thereby turning the material hoisted onto the steel platform inside the chimney.

[0026] A rotating handle 12 is fixedly installed at the end of the support plate 6. After the second motor 13 is de-braked, the mounting plate 8 can be easily rotated by rotating the handle 12, thereby rotating the rotary arm 9 on the mounting plate 8.

[0027] A reinforcing plate is evenly fixed between the bottom of the support plate 6 and the column 1, thereby increasing the strength of the support plate 6.

[0028] A connecting bracket 16 is fixedly installed at the bottom end of the rotary arm 9. A guide sleeve 17 is fixedly connected to the end of the connecting bracket 16. The guide sleeve 17 is fitted onto the traction rope 14. Multiple guide components 18 are evenly fixedly installed on the top of the rotary arm 9. The guide component 18 includes two L-shaped supports 21. The L-shaped supports 21 are fixedly installed on the rotary arm 9. Two guide wheels 22 are symmetrically rotatably connected inside the L-shaped supports 21. The traction rope 14 passes between the two guide wheels 22. When the traction rope 14 is lifted, it is pulled and reciprocates. The traction rope 14 moves between the take-up roller 10 and the steering pulley 19 under the guidance of the two guide wheels 22 of the guide component 18. In the vertical direction, it is limited by the guide sleeve 17 fixedly connected to the end of the connecting bracket 16, which reduces the risk of the traction rope 14 disengaging from the steering pulley 19 and increases the stability of the traction rope 14 during use.
