Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, specifically to a sewage treatment fine screen motor reducer hoisting device. Background Technology

[0002] In the process of wastewater treatment, due to the high content of impurities in the wastewater, it is necessary to treat the wastewater to a certain extent before it enters the wastewater treatment system in order to protect subsequent treatment equipment, improve treatment efficiency, and ensure water quality safety. Common existing treatment equipment includes coarse screens, fine screens, and primary sedimentation tanks.

[0003] There are various models of fine screens. Taking the internal flow fine screen as an example, it is rectangular in shape and driven by a motor reducer. The motor reducer is located high up. In actual use, if there are many impurities in the influent, the fine screen is prone to overload operation. This can easily damage the bearings of the motor reducer drive shaft. Therefore, in actual production, it is necessary to disassemble the motor reducer and replace the damaged bearings.

[0004] The common maintenance method currently is to erect scaffolding. Scaffolding is erected on both sides of the fine grid, with crossbeams supporting the middle. Manual hoists are hung on the crossbeams to disassemble and assemble the motor reducer, thereby enabling the maintenance of the bearings. However, the scaffolding is time-consuming and labor-intensive, causing inconvenience to the maintenance work. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the prior art by providing a hoisting device for a fine screen motor reducer in wastewater treatment, thereby facilitating the disassembly and assembly of the motor reducer during maintenance of the drive shaft bearings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sewage treatment fine screen motor reducer hoisting device, based on an internal flow fine screen, including a hoisting frame, the hoisting frame being rotatably installed above the top of the internal flow fine screen motor reducer side, a hanging rod being provided above the hoisting frame, a manual hoist being hung on the hanging rod, the rear side of the hanging rod being fixedly connected to one end of a cable, the other end of the cable being fixedly connected to the top of the internal flow fine screen away from the motor reducer side, and the vertical projection of the hanging rod being located outside the internal flow fine screen motor reducer side.

[0007] Furthermore, the lifting frame includes a mounting base and a rotating rod, with the rotating rod rotatably connected to the mounting base; two mounting bases are provided, respectively located on both sides above the top of the inner inlet fine screen motor reducer. Each mounting base includes a mounting plate, which is fixedly connected to the top of the inner inlet fine screen. A sleeve is fixedly connected to the mounting plate, and both ends of the rotating rod are respectively rotatably connected to the sleeve for limiting.

[0008] Furthermore, ribs are provided between the two sides of the sleeve and the mounting plate.

[0009] Furthermore, the rotating rod is provided with first pin holes at both ends, and second pin holes are provided on the sleeves on both sides respectively. The first pin holes and the second pin holes cooperate to install and fix the pins.

[0010] Furthermore, the lifting frame includes support rods, which are fixedly connected to rotating rods. There are two support rods, and a hanging rod is fixedly connected between the two support rods. The two support rods, the hanging rod, and the rotating rod between the two support rods are trapezoidal in space.

[0011] Furthermore, there are two cables. One end of each cable is fixedly connected to both sides of the hanging rod, and the other end of the cable is fixedly connected to the top of the inner flow fine grid away from the motor reducer. The hanging rod, the two cables, and the line connecting the two cables at the fixed point above the inner flow fine grid form a trapezoid in space.

[0012] Furthermore, a limiting support block is provided on the rotating rod. When the hoisting device is in the unfolded state, the limiting support block is in contact with the outer side wall of the top of the inner flow fine grid motor reducer.

[0013] Furthermore, when the lifting device is in the folded state, the lifting frame and the cable are placed flat above the top of the inner inlet fine grid.

[0014] The beneficial effects of this utility model are: the utility model has a simple structure and is safe to use; during use, it can effectively avoid the traditional scaffolding dismantling and assembly operations, making it more convenient to use; and after use, it can be folded and placed on top of the fine grid, making it more aesthetically pleasing and convenient for actual production use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0024] Embodiments of this utility model:

[0025] like Figure 1-6 As shown, the lifting device 2 of this utility model is based on the inlet fine screen 1 of a sewage treatment plant. It includes a lifting frame 21, which is arranged above the top of the inlet fine screen 1 on one side of the motor reducer 11. The lifting frame 21 includes a mounting base 23. There are two mounting bases 23, which are located on both sides of the top of the inlet fine screen 1 on the side of the motor reducer 11. The mounting base 23 includes a mounting plate 231, which is fixedly connected to the top of the inlet fine screen 1. A sleeve 232 is provided on the mounting plate 231. Reinforcing ribs 233 are provided between the two sides of the sleeve 232 and the mounting plate 231. A solid rotating rod 211 is rotatably installed through the sleeve 232 in the mounting bases 23 on both sides. The rotating rod 211 has a first pin hole 2111 on both sides and a second pin hole 2321 on the sleeves 232 on both sides. The first pin hole 2111 and the second pin hole 2321 cooperate with each other and are connected to the positioning pin 234.

[0026] A support rod 212 is fixedly connected to the rotating rod 211. There are two support rods 212. A hanging rod 213 is fixedly connected between the upper sides of the two support rods 212. A hand chain hoist is hung on the hanging rod 213. The hand chain hoist cooperates with the motor reducer 11. The two support rods 212, the hanging rod 213 and the rotating rod 211 between the two support rods 212 are arranged in a trapezoidal shape. A cable 22 is connected to the rear of each side of the hanging rod 213. The other ends of the two cables 22 are fixed to the top of the inner flow fine screen 1 on the side away from the motor reducer 11. The two cables 22, the hanging rod 213 and the line connecting the two cables 22 also form a trapezoidal shape in space.

[0027] A limiting support block 24 is provided on the rotating rod 211. Multiple limiting support blocks 24 can be provided. When the lifting frame 21 is in the unfolded state, the limiting block is in contact with the outer side wall above the motor reducer 11 of the inner flow fine screen 1. When the lifting frame 21 is in the folded state, the lifting frame 21 and the cable 22 are placed flat above the inner flow fine screen 1.

[0028] The principle of this utility model is as follows:

[0029] When using this utility model, if it is necessary to disassemble the motor reducer 11, on-site maintenance personnel can use an engineering ladder or similar means to erect the lifting frame 21, then install the positioning pin 234 and hang a manual hoist to lift the motor reducer 11, which facilitates the maintenance of the transmission shaft bearing. After use, the positioning pin 234 can be removed, and the lifting frame 21 can be placed flat on top of the fine grid, which is both aesthetically pleasing and does not affect its use.

[0030] Furthermore, by setting the cable 22 and the limiting support block 24 in this utility model, the safety of use is further guaranteed (the cable 22 bears the main force, and the limiting support block 24 can play a further protective role when the cable 22 breaks accidentally), which facilitates safe use on site, ensures the personal safety of operators, avoids traditional scaffolding operations, and is more convenient for use on the production site.
