Description

Technical Field

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

[0002] In compressed air energy storage projects, underground chambers are often used for gas storage. Therefore, the underground chambers need to be well sealed. At present, the sealing methods for underground chambers include rubber sealing. However, the inner diameter of the underground chamber is very large. When rubber is used for sealing, there is a splicing gap (including longitudinal gap and circumferential gap) between two adjacent spliced ​​rubbers. The splicing gap needs to be vulcanized to achieve the sealing effect.

[0003] Considering the high temperature (nearly 200℃) and high pressure (no more than 1MPa) of rubber vulcanization, and the need to maintain a certain vulcanization time to complete the entire vulcanization process, the conventional manual scaffolding and handheld vulcanization equipment operation methods have the problems of high construction difficulty, low construction efficiency and high construction risk factor. At present, there are few cases of manual scaffolding construction in the vulcanization of rubber sealing layers for gas storage chambers.

[0004] In summary, it is necessary to develop a vulcanization device and application method for a rubber sealing layer for a gas storage chamber to solve the problems existing in the prior art using manual scaffolding and handheld vulcanization equipment. Summary of the invention

[0005] The purpose of the present invention is to provide a vulcanization device and application method for a rubber sealing layer for a gas storage chamber, which can solve the problems of great construction difficulty, low construction efficiency and high construction risk factor in the prior art using manual scaffolding and handheld vulcanization equipment.

The tilting situation occurs during the process, ensuring the smooth progress of the vulcanization operation; the vulcanization mechanism includes a hot melt mold for vulcanizing rubber; the longitudinal movement mechanism is connected to the lifting drive assembly, which is used to drive the gantry assembly to link the vulcanization mechanism along the axial direction in the gas storage chamber to the target operation point; the transverse movement drive assembly in the gantry assembly is used to assist the vulcanization equipment in finding the center, until the main beam and the center point of the gas storage chamber coincide with each other to complete the centering; during the vulcanization operation, the present invention uses the vulcanization mechanism to complete the rubber vulcanization operation.

Therefore, the present invention does not need to use manual scaffolding and handheld vulcanization equipment to complete the rubber vulcanization sealing operation for the gas storage chamber, which can not only ensure the quality of rubber vulcanization, but also shorten the construction period and reduce construction risks.

[0061] (10) The present invention adopts a combination of a gantry assembly and a longitudinal movement mechanism to coordinately realize the longitudinal movement of the vulcanization mechanism, driving the vulcanization mechanism to complete the vulcanization operation of the annular gap and the vulcanization operation of the longitudinal gap. Specifically, when the annular gap is vulcanized, the mold body is the second mold body, the heating rod is started for heating, and the electric control cabinet is started to control the rotary reducer to link each group of the vulcanization mechanism to rotate, so as to complete the vulcanization operation of the annular gap; when the longitudinal gap is vulcanized, one of the mold bodies is replaced with the first mold body, the heating rod is started for heating, and the remaining mold bodies are the second mold body, the heating rod is controlled to stop heating, the electric control cabinet is started to control the rotary reducer to link the first mold body in the vulcanization mechanism to rotate to the longitudinal gap position, the longitudinal movement cylinder is started to extend, and the longitudinal movement mechanism is driven to move along the axial direction in the gas storage chamber by linking the moving trolley and the driven trolley to complete the vulcanization operation.

[0092] See also Figure 3 The tightening assembly also includes a hydraulic accumulator (not shown in the figure); the hydraulic accumulator is connected to the tightening cylinder 1.4 through an oil circuit, so that when the tightening cylinder 1.4 is depressurized, the tightening cylinder 1.4 can be pressurized in time.

[0130] If the tensioning cylinder 1.4 is depressurized during the vulcanization operation, the hydraulic accumulator will promptly replenish the pressure of the tensioning cylinder 1.4;

[0131] At the end of the vulcanization operation, the tensioning cylinder 1.4 is controlled to release pressure, and the first sleeve 1.2 is linked to drive the hot melt mold to retract;
