Description

Technical Field

[0001] This utility model relates to a gas holder cable collection device. Background Technology

[0002] As a core piece of equipment for storing and distributing coal gas, the gas holder plays a crucial role in balancing and regulating the energy systems of metallurgical, chemical, and other enterprises. The gas holder is cylindrical or prismatic in appearance, consisting of a base plate, columns, side plates, a top, and a conduit. Internally, it houses a piston that can move up and down. Coal gas enters from the bottom of the holder and is stored in the space formed by the base plate, side plates, and piston plate. The continuous up-and-down movement of the piston controls the flow of gas, thus requiring stable and safe long-term movement. On one hand, with the continuous development of sensors and detection instruments, the gas holder piston needs to be equipped with instruments to detect its position, speed, tilt, drift, torsion, and a fixed carbon monoxide detector, allowing operators to monitor its real-time status. On the other hand, as production capacity expands, newly built gas holders are becoming increasingly larger, resulting in a greater distance between the piston plate and the top plate. The above two factors have led to a gradual increase in cable length and diameter. Even when using flexible cables, it was found during the actual commissioning phase that it was impossible to guarantee that the cable would enter the take-up reel completely as intended. If it could not enter the take-up reel completely, the cable would easily be pulled off when the piston descends, which is very detrimental to maintenance and safety.

[0003] Chinese patent CN204416794U proposes a cable winding device that can effectively prevent cables from tangling and knotting. The device includes an inner cone, an outer cylinder, a cylinder bottom, and a base. The inner cylinder is located inside the outer cylinder. The upper part of the outer cylinder is trumpet-shaped, and the lower part is cylindrical. The upper part of the inner cone is conical, and the lower part is cylindrical. When the gas holder rises, the cable falling into the winding device is neatly coiled according to the diameter of the inner cone. When the gas holder descends, the cable is pulled upwards in an orderly manner under the guidance of the inner cone. While this patent does prevent cables from tangling and knotting, in actual operation, due to the inherent rigidity of the cable and its length of tens to hundreds of meters, its swing amplitude is also significant. Furthermore, the height of the winding device is insufficient, sometimes preventing the cable from entering the device as designed.

[0004] Chinese patent CN221026980U discloses a flexible cable collector for a gas holder, comprising a support, a cable guide ring, a cable guide tube, and a collection cylinder. The support is fixedly connected to the top surface of a piston. The cable guide ring, cable guide tube, and collection cylinder are coaxially arranged. The cable guide ring and collection cylinder are respectively fixedly connected to the support. The collection cylinder is located below the cable guide ring and has an upward-opening collection cavity. The collection cavity is inverted conical in shape. The cable guide tube is disposed inside the collection cavity and is fixedly connected to the bottom end of the collection cylinder. However, due to the long length and certain rigidity of the cable, verticality cannot be guaranteed, and the cable may fail to enter the guide ring due to significant swaying. Utility Model Content

[0020] When the scissor lift is in a stretched state, it should not be stretched beyond its own limit. In other words, the scissor lift should have a certain margin of extension to ensure that it is not under stress and will not break.

[0021] To achieve the above objectives, the gas holder of this utility model includes the aforementioned gas holder cable collection device.

[0022] This utility model employs a telescopic device that can extend and retract in the vertical direction as the piston moves up and down.

[0033] Example

[0034] Figures 1 to 4 This is a schematic diagram of the cable collection device for a large-capacity single-section gas holder in this embodiment. Due to the large capacity of the gas holder, the distance from the piston plate to the top plate is greater, and the cable is relatively thick and has a certain degree of rigidity. The gas holder cable collection device includes a telescopic device 1, a cable gathering device 2, and a conductor ring 3. The upper end of the telescopic device 1 is fixed to the vent platform on the top plate of the gas holder, and the lower end is fixed to the upper edge of the cable gathering device. The cable gathering device 2 is fixed at the center of the piston. The conductor ring 3 is set on the telescopic device 2, with one set approximately every 5m. The inner diameter of the conductor ring should be more than 1.5 times the outer diameter of the cable to allow the cable to slide (pass through) smoothly within it.

[0035] The telescopic device 1 consists of an upper connecting frame 101, a lower connecting frame 102, and a scissor lift frame; the upper connecting frame 101 is located at the upper part of the scissor lift frame and is used to connect the scissor lift frame and the cabinet top vent platform; the lower connecting frame 102 is located at the lower part of the scissor lift frame and is used to connect the scissor lift frame and the cable management device 2.

[0036] The upper connecting frame 101 can be made of metal strips, angle steel, or strip steel plates, etc. Two slides are provided inside corresponding to the two hinge points at the upper end of the scissor lift. The scissor lift is connected to the upper crossbar through the slider 105. During the up and down movement of the piston, the connection point of the upper connecting frame 102 of the scissor lift can slide in the slide through the slider 105.

[0037] The lower connecting frame 102 is provided with a slide rail inside. The scissor lift and the lower crossbar 102 are connected by a slider 105. During the up and down movement of the piston, the connection point of the lower connecting frame 102 of the scissor lift can slide in the slide rail 105 through the slider.

[0038] The scissor lift 3 consists of several strip plates 103, bolts, and nuts 104. Each pair of strip plates is arranged in an X-shape, with movable bolts and nuts at the intersection of the X shapes. The lower two ends of the upper X shape are connected to the upper two ends of the next X shape, with movable bolts and nuts at the connection points. When the piston is at its lowest point, the scissor lift is in a stretched state; when the piston reaches its highest position, the scissor lift is in a retracted state.

[0039] The aforementioned cable management device 2 consists of an inner conical cylinder 201, an outer cylinder 202, a flared mouth 203, and a support 204. The inner conical cylinder 201 is placed at the center of the outer cylinder 202. The top of the outer cylinder 202 needs to be ground into a rounded corner, and the cylinder needs to be ground to a smooth surface, free from welding slag and burrs.

[0040] The aforementioned conductor ring 3, several conductor rings are set on the scissor lift 1, and the cable is laid vertically from the top vent platform of the cabinet to the center of the piston. During laying, it needs to pass through the conductor ring to ensure that the cable is received into the cable collection device during the cable reeling process.

[0041] When the scissor lift is in a stretched state, it should not be stretched beyond its own limit. In other words, the scissor lift should have a certain margin of extension to ensure that it is not under stress and will not break.
