Description

Technical Field

[0001] The present invention relates to the technical field of rubber vulcanization equipment, and in particular to an umbrella-type vulcanization equipment for a rubber sealing layer used in a gas storage chamber and an application method thereof. Background Art

[0002] Compressed air energy storage projects often utilize underground chambers for gas storage. Therefore, these chambers must be properly sealed. Currently, rubber seals are commonly used to seal underground chambers. However, the large inner diameter of underground chambers necessitates the use of multiple rubber seals. Furthermore, gaps exist between adjacent rubber seals (both longitudinal and circumferential), requiring vulcanization to achieve a seal.

[0003] Considering the high temperature (nearly 200°C) and high pressure (no less than 1 MPa) required for rubber vulcanization, as well as the required time to complete the vulcanization process, conventional manual scaffolding and handheld vulcanizing equipment present significant challenges, including high construction difficulty, low efficiency, and a high risk factor. Currently, manual scaffolding is rarely used in the vulcanization of rubber seals for gas storage chambers.

[0004] Furthermore, during chamber construction, most of the chamber entrance must be sealed, often leaving only a 1.2m diameter artificial passage. This means that when vulcanizing the rubber sealant, the vulcanizing equipment must be disassembled, transported through the artificial passage, and then reassembled inside the chamber. This disassembly and assembly process is cumbersome, time-consuming, and labor-intensive.

[0005] In summary, it is necessary to develop an umbrella-type vulcanizing equipment and application method for rubber sealing layers for gas storage chambers to solve the problems existing in the existing technology of using manual scaffolding and handheld vulcanizing equipment, as well as the problem that the existing vulcanizing equipment needs to be disassembled and assembled when passing through artificial channels.

[0025] In a second aspect, the present invention provides an application method of the umbrella-type vulcanizing equipment, comprising:

[0026] Step S1: Before preparing for the vulcanization operation, the first support frame and the second support frame in the umbrella vulcanization equipment are removed, and the driving member is started to sequentially link the sprocket, the chain and the sliding sleeve to perform a retraction action, and the sliding sleeve links the first tightening and retracting connecting rod and the second tightening and retracting connecting rod to retract the vulcanization assembly and the tightening adjustment assembly; the umbrella vulcanization mechanism in the retracted state is transported to the gas storage chamber via a transport trolley, and the first support frame and the second support frame are sequentially installed on both ends of the main beam.

[0034] (1) The present invention provides an umbrella-type vulcanizing device for rubber sealing layers for gas storage chambers, which can not only solve the problems of high construction difficulty, low construction efficiency and high construction risk factor in the prior art using manual scaffolding and handheld vulcanizing equipment, but also solve the problem that the prior vulcanizing equipment needs to be disassembled and assembled when passing through an artificial passage. Specifically, before preparing for the vulcanization operation, a tightening and retracting drive assembly is used to drive the vulcanizing assembly to be retracted along the main beam, and the umbrella-type vulcanizing mechanism in the retracted state is transported and moved to the target operation point in the gas storage chamber through an artificial passage; during the vulcanization operation, the tightening and retracting drive assembly is first used to drive the vulcanizing assembly to be stretched and tightened, and then the hot melt mold in the vulcanizing assembly is used to complete the rubber vulcanization operation. Therefore, the present invention can complete the rubber vulcanization sealing operation for the gas storage chamber without the need for manual scaffolding and handheld vulcanizing equipment, which can not only ensure the quality of rubber vulcanization, but also shorten the construction period and reduce construction risks. In addition, the present invention utilizes a tightening and retracting drive assembly to retract the curing assembly, facilitating the transport of the retracted umbrella-type curing mechanism into the gas storage chamber via a manual passage, eliminating the need for disassembly and assembly of the umbrella-type curing mechanism. Furthermore, the umbrella-type curing equipment employed in the present invention is lightweight, compact when retracted, and easy to use.

[0035] (2) The present invention provides an application method of an umbrella-type vulcanizing device for a rubber sealing layer for a gas storage chamber. The vulcanizing operation can be performed by remote control, which greatly improves the construction efficiency and safety. In addition, before preparing for the vulcanizing operation, only the first support frame and the second support frame need to be disassembled and assembled, which has the advantage of being easy to use. If the first tightening cylinder and the second tightening cylinder experience pressure relief during the vulcanizing operation, the first hydraulic accumulator will promptly replenish the pressure for the first tightening cylinder, and the second hydraulic accumulator will promptly replenish the pressure for the second tightening cylinder, thereby ensuring that the vulcanizing operation is successfully completed.

The rotary drive component 4 is fixed to the main beam 1 through a connecting frame. Before preparing for the vulcanization operation, the vulcanization assembly 3 is driven to be retracted along the main beam 1 by tightening and retracting the drive assembly 2, so that the umbrella-type vulcanization mechanism in the retracted state can be transported to the gas storage chamber through an artificial channel without disassembling and assembling the umbrella-type vulcanization mechanism.

[0044] The vulcanization assembly 3 also includes a first telescopic sleeve structure 3.2 and a first tightening assembly (not shown in the figure); the first telescopic sleeve structure 3.2 includes a first sleeve 3.2.1 and a second sleeve 3.2.2 which are coaxially slidably arranged, and an annular gap is reserved between the two; one end of the first tightening assembly is hinged to the end of the first sleeve 3.2.1 away from the second sleeve 3.2.2, and the other end is hinged to the end of the second sleeve 3.2.2 away from the first sleeve 3.2.1; the hot melt mold 3.1 is arranged on the end of the first sleeve 3.2.1 away from the second sleeve 3.2.2; the end of the second sleeve 3.2.2 away from the first sleeve 3.2.1 is the first connecting end, which is hinged to the main beam 1.

[0045] The first tightening assembly includes a first tightening cylinder, the fixed end of which is hinged to the second sleeve 3.2.2, and the operating end of which is hinged to the first sleeve 3.2.1. A stroke sensor (not shown) is provided in the first tightening cylinder to facilitate real-time monitoring and adjustment of the telescopic length of the first telescopic sleeve structure 3.2, so as to accurately achieve the first tightening cylinder and the first sleeve 3.2.1 to drive the hot melt mold 3.1 to the rubber gap to be vulcanized.

(Note: During vulcanization, after the ends of the mold body 3.1.1 have cooled, the rubber in contact with them is in a semi-cooked state, and only when the next overlapping vulcanization process is performed with the raw rubber can the vulcanization be successful. If the ends of the mold body 3.1.1 are not cooled, the rubber in contact with the ends of the mold body 3.1.1 is completely cooked, and a gap will appear in the overlapping area during the next vulcanization process with the raw rubber.)
