Description

Manual two-way cut-off equipment

Technical Field

The utility model relates to a gate that can be used to outdoor feedwater and drainage control specifically says for a manual two-way cut-off equipment that can assemble, but the wide application is in projects such as waterworks, sewage plant, irrigation and drainage, oil, chemical industry, metallurgy, environmental protection, electric power, small reservoir weir, river.

Background

At present, in outdoor water supply and drainage engineering, a manual bidirectional interception facility is also called a gate, is a control facility for closing and opening a drainage (drainage) water channel, and is an important component of a hydraulic engineering building. Can be used for intercepting water flow, controlling water level, regulating flow, discharging silt and floating objects and the like. The existing manual bidirectional closure facility mainly comprises a door body frame, a door body, a sealing piece, a hoist, a screw nut assembly, a fixing bolt and other parts. The main material is stainless steel, and the rubber is soft and sealed.

When the gate operates, the headstock gear is rotated to drive the transmission screw to operate, so that the door body reciprocates up and down relative to the door body frame, the sealing seat surfaces of the door frame and the door body are effectively attached, and the effect of cutting off water flow is achieved. The door body frame is a supporting member of the gate and also is a running track of the gate, and is fixedly installed in the secondarily poured concrete of the gate pier and the gate bottom plate by foundation bolts.

The common manual bidirectional closure facility is a lifting gate, and a door body, a sealing surface, a shaft guide frame, a guide rail and a door frame of the manual bidirectional closure facility are installed together. The width of the door frame is the width of the water flow channel, and the height is the sum of the height of the water flow channel and the height of the gate door body. When the water-saving type drainage device works normally, the door bodies are all arranged in the channel and used for cutting off water flow. When the water flow channel does not work, the door body is upwards opened completely through the hoist and hung on the door body frame, and the door body is arranged above the channel, so that the water flow in the channel is ensured to be smooth. The existing gate installation mode cuts off an overhaul channel above a water flow channel, and the passage of maintainers is hindered. But also brings obstacles to daily traffic and inconvenience to production work.

Detailed Description

The first embodiment is as follows:

as shown in fig. 2, the utility model discloses a manual two-way cut-off equipment includes door frame, the door body 1, headstock gear 6 and screw-nut subassembly 5, and door frame divide into upper ledge 2 and underframe 3, and upper ledge 2 and underframe 3 adopt components of a whole that can function independently demountable assembly structure. The hoist 6 and the upper part of the screw-nut component 5 are arranged on the upper part of the upper frame, and the bottom of the screw-nut component 5 is detachably assembled with the door body 1.

The door body 1 is matched with the lower frame 3, and the door body 1 can slide up and down along the lower frame 3 after being installed. When the water channel is used, the lower frame 3 is fixedly arranged on the channel walls 4 at the two sides and the bottom of the water channel, and the channel walls of the water channel are of a concrete prefabricated structure. The door body 1 is hung into the lower frame 3 by using a crane to hang the hanging ring 7. When the door body 1 falls to the bottom of the lower frame 3, water flow in the ditch can be blocked. The hanging ring 7 arranged at the top of the door body 1 is also used for hanging the door body away by adopting equipment such as a crane and the like to open a ditch when closure is not needed.

For the occasion that the hoist is required to hoist or the door body needs to be lifted and closed frequently, the upper frame 2 is assembled on the upper portion of the lower frame 3 through bolts, the screw rod nut assembly 5 is assembled with the door body 1, the hoist is in transmission connection with the screw rod nut assembly 5, and an auxiliary supporting structure can be arranged during the assembly of the upper frame and the lower frame. After assembly, the upper frame, the hoist and the screw nut component are erected on the upper part of the lower frame, and the hoist can control the lifting of the door body.

When the upper frame is not assembled, the upper part of the lower frame 3 crosses the canal walls at two sides of the canal and is erected with the grating plates 8 at the upper part of the canal to form a pedestrian and maintenance passage at the upper part of the canal.

When the closure control is not needed, the door body, the upper frame, the hoist and the screw nut assembly are disassembled or not assembled, and the door body, the upper frame, the hoist and the screw nut assembly are collected to a warehouse for storage.

Example two:

the present example is further designed in that a guide rail chute guide structure is provided between the door body 1 and the lower frame 3. The upper part of the lower frame is also provided with a bracket which is used for connecting the upper frame and the lower frame and supporting and stabilizing the upper frame and the lower frame and other parts.
