Description

Technical Field

[0001] This utility model belongs to the field of industrial hoisting equipment technology, specifically relating to a retractable hoisting mechanism for a large filter cylinder. Background Technology

[0002] Large filter cartridges are primarily used for water purification, removing impurities, harmful substances, or pollutants from water through physical, biological, or chemical methods. Their applications include industrial wastewater treatment, drinking water purification, and aquarium circulation systems. In industrial production, large filter cartridges are widely used for the filtration and purification of gases or liquids. Traditional methods for hoisting large filter cartridges have several drawbacks: firstly, hoisting mechanisms are mostly fixed structures, occupying a large space and making them inconvenient to store when not in use, thus affecting the utilization of space in the production area; secondly, existing hoisting mechanisms are not sufficiently stable in securing the filter cartridges during hoisting, easily leading to shaking or even detachment during transport, posing safety hazards; furthermore, some hoisting mechanisms are complex to operate, requiring multiple people to complete the hoisting task, reducing work efficiency. Therefore, we propose a foldable hoisting mechanism for large filter cartridges. Utility Model Content

[0003] The purpose of this invention is to provide a retractable hoisting mechanism for large filter cartridges to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a retractable hoisting mechanism for a large filter cartridge, comprising a base plate, a column fixedly mounted on the top of the base plate, a sleeve shaft rotatably mounted on the top of the column, a support arm fixedly connected to one side of the sleeve shaft, an adjusting arm rotatably connected to the end of the support arm, a fixing plate fixedly connected above one end of the adjusting arm, a motor fixedly mounted above the fixing plate, a main wheel rotatably mounted on the outer surface of the fixing plate, one side of the main wheel being fixedly connected to the output end of the motor, a steel wire rope wound around the surface of the main wheel, a guide wheel rotatably mounted on one side of the adjusting arm, one side of the steel wire rope being wound around the upper surface of the guide wheel, and a clamping mechanism being provided at the lower end.

[0005] Preferably, the clamping mechanism is provided with a first connecting rod and a second connecting rod. The ends of the first connecting rod and the second connecting rod are rotatably connected by hooks. The bottom ends of the first connecting rod and the second connecting rod are respectively symmetrically rotatably connected to connecting rods. The connecting rods are rotatably connected to each other in a cross manner. A clamping plate is fixedly connected to one side of the bottom of each connecting rod.

Screws are rotatably threaded through the four corners of the surface of the fixing blocks, and a support plate is rotatably installed at the bottom end of the screws.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1.

[0014] 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.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a stackable hoisting mechanism for a large filter cartridge, including a base plate 1, a column 2 fixedly installed on the top of the base plate 1, a sleeve shaft 3 rotatably installed on the top of the column 2, a support arm 4 fixedly connected to one side of the sleeve shaft 3, an adjusting arm 5 rotatably connected to the end of the support arm 4, a fixing plate 6 fixedly connected above one end of the adjusting arm 5, a motor 7 fixedly installed above the fixing plate 6, a main wheel 8 rotatably installed on the outer surface of the fixing plate 6, a side of the main wheel 8 fixedly connected to the output end of the motor 7, a steel wire rope 10 wound around the surface of the main wheel 8, a guide wheel 9 rotatably installed on the side of one end of the adjusting arm 5, a side of the steel wire rope 10 wound around the upper surface of the guide wheel 9, and a clamping mechanism 11 provided at the lower end.

[0016] Specifically, the clamping mechanism 11 is provided with a first connecting rod 1101 and a second connecting rod 1102. The ends of the first connecting rod 1101 and the second connecting rod 1102 are rotatably connected by a hook 1103. The bottom ends of the first connecting rod 1101 and the second connecting rod 1102 are respectively symmetrically rotatably connected to connecting rods 1104. The connecting rods 1104 are rotatably connected to each other in a cross manner. A clamping plate 1105 is fixedly connected to one side of the bottom of the connecting rod 1104.

[0017] Specifically, a limiting rod 1108 is rotatably installed on one side of the first connecting rod 1101, a limiting hook 1110 is connected to the bottom end of the limiting rod 1108, a gripping rod 1109 is connected to the top of the limiting rod 1108, and a limiting shaft 1111 is installed on one side of the connecting rod 1104.

[0018] Specifically, a protective pad 1106 is connected to one side of the clamping plate 1105, and a handle 1107 is fixedly installed on one side of the connecting rod 1104.

[0019] Specifically, a limiting groove 14 is formed on one side of the surface of the column 2, and a tripod 12 is fixedly installed on one side of the bottom of the support arm 4. A pulley 13 is rotatably installed on the bottom of the tripod 12, and the pulley 13 is limited and slidably connected to the inside of the limiting groove 14.

[0020] Specifically, fixing blocks 15 are symmetrically installed on both sides of the bottom of the base plate 1, and movable wheels 16 are installed at the bottom of the fixing blocks 15. Screw rods 17 are threaded through the four corners of the surface of the fixing blocks 15, and support plates 18 are rotatably installed at the bottom of the screw rods 17.

[0021] In this embodiment, the device is moved to a suitable position, and then the adjusting arm 5 is unfolded. The motor 7 drives the main wheel 8 to rotate, thereby releasing the wire rope 10. The wire rope 10 drives the clamping plates 1105 on both sides of the clamping mechanism 11 to descend to both sides of the filter cylinder. According to the outer diameter of the filter cylinder, the handle 1109 is rotated to separate the limiting hook 1110 below the limiting rod 1108 from the limiting shaft 1111. At this time, the two sets of connecting rods 1104 will lose their limiting function. When the motor 7 drives the wire rope 10 and the clamping mechanism 11 to rise, the connecting rods 1104 will automatically drive the clamping plates 1105 on both sides to clamp and fix the sides of the filter cylinder. The operator can hold the handle 1107 to move the adjusting arm 5, which can lift and transport the filter cylinder to the designated installation position. The installation of the movable wheel 16 increases the overall flexibility of the device, making it easy to move the position as needed. The rotating screw 17 drives the support plate 18 to move downward, which can provide support and stability to the base plate 1. When the support arm 4 rotates, it will drive the pulley 13 to move in a ring inside the limiting groove 14 through the tripod 12, which reduces the friction of the support arm 4 during rotation.
