Self-elevating type combined gate arrangement structure

Abstract

The invention discloses a self-elevating type combined gate arrangement structure. The self-elevating type combined gate arrangement structure comprises a gate body, a hydraulic hoist and steel embedded pieces arranged at the bottom of a gate groove; the hydraulic hoist comprises a hydraulic oil pump station, a hydraulic cylinder, a multi-stage piston rod and a pressure oil pipe; and the hydrauliccylinder penetrates through the gate body internally from top to bottom and is fixedly connected with a beam body of the gate body, the pressure oil pipe is fixedly arranged along the outer wall of the hydraulic cylinder from top to bottom and is connected with an oil inlet and an oil outlet of the hydraulic cylinder correspondingly, the multi-stage piston rod is supported on the steel embedded piece at the bottom in the elevating process of a gate, and the hydraulic oil pump station is fixed to the top of the gate body or placed on an overhaul platform. According to the self-elevating type combined gate arrangement structure, through a combined structure of the gate body and a multi-stage hydraulic cylinder, the gate can be opened and closed flexibly and freely depending on the own structure, no additional equipment needs to be adopted to assist the opening and hoisting of the gate, the opening and closing operation of the gate being affected by instability of the additional equipment is avoided, safe and reliable operation of gate equipment is realized, and safety of the gate is greatly improved.

Description

technical field [0001] The invention designs the technical field of steel gates in water conservancy and hydropower projects, in particular to an arrangement structure of a self-elevating combined gate. Background technique [0002] The steel gate is one of the important components of hydraulic structures. Its function is to close the orifice of the hydraulic structure, and to open the orifice in whole or in part as required to adjust the upstream and downstream water levels, discharge flow, and discharge. boats, removing dust or floating objects, etc. With the needs of the development of water conservancy and hydropower and the increasing level of industrial production, in recent years, the proportion of gate devices in the total construction cost of hydraulic structures has increased, generally accounting for about 10% to 30%. Therefore, the reliability of the steel gate is particularly important to the national economy and people's livelihood. [0003] In most projects,...

Problems solved by technology

Since the gate structure is located underwater, if the automatic hook-and-detach beam is used for operation, it needs to be "blindly grasped" under the condition of no vision underwater, which is very prone to inaccurate alignment and ineffective hook and detachment; if the gate is operated with a pull rod , limited by the head of the hoist or the height of the building, the tie rods are often made in the form of multi-section connections. During the lifting process, it is necessary to repeatedly lock and remove the upper tie rods and connect the lower tie rods to continue lifting operations. The operating procedure Complex, long time, inconvenient maintenance
