Description

Technical Field

[0001] The utility model relates to the technical field of assembled equipment for water conservancy projects, in particular to a fast assembled exposed-top arc-shaped steel gate. Background Art

[0002] Arc steel gates are widely used in water conservancy and hydropower projects. They have the characteristics of simple structure, small height and thickness of the required gate piers, no gate slots that affect the dynamics of water flow, small opening and closing force, and easy operation. Arc gates are gates with a partially curved surface of a cylinder as the water retaining surface. According to the depth of the water level above the gate top, they are divided into exposed top type and submerged hole type. When the reservoir water level does not exceed the gate top, it is called an exposed top type arc gate; when the reservoir water level is higher than the gate top, it is called a submerged hole type arc gate.

[0003] The existing curved steel gate is generally opened and closed by moving the gate up and down in the track groove of the dam body. After long-term use, sediment accumulation in the track groove is inevitable, which will inevitably affect the opening and closing of the curved steel gate to a certain extent.

[0004] After searching, the Chinese patent with publication number CN209277128U discloses an arc-shaped steel gate. The hydraulic rod of the hydraulic cylinder of the utility model contracts, driving the free end of the gate to rotate, so that the gate is opened, and then the hydraulic rod of the hydraulic cylinder extends, driving the free end of the gate to rotate, so that the gate is closed. The gate is easy to open and close, and the gate does not need to be opened and closed with the help of a track groove, avoiding the situation that the gate cannot be opened or closed due to too much sediment in the track groove.

[0005] However, when the above-mentioned arc-shaped steel gate is actually used, the assembly process is relatively complicated when assembling and connecting the steel gate to the dam body. At the same time, there are more bolt connections and more steps required, which affect the efficiency of assembly. At the same time, during the maintenance process, if damage occurs, the efficiency of repair and replacement is relatively slow, which affects subsequent use. Utility Model Content

[0006] The purpose of the utility model is to provide a quick-assembled exposed-top arc-shaped steel gate in order to solve the above-mentioned problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fast-assembly exposed-top arc-shaped steel gate, comprising a load-bearing column, wherein an assembly mechanism is arranged on the left side of the load-bearing column;

[0008] The assembly mechanism includes multiple first support arms, multiple first support arms have buffer gaskets movably connected at one end, multiple buffer gaskets have bolts movably connected inside, multiple buffer gaskets have second support arms movably connected on the left side, multiple first support arms and second support arms have maintenance guardrails fixedly connected on the front sides, multiple second support arms have fixedly connected on the left sides with fixed connecting plates, multiple second support arms have two load-bearing cross plates fixedly connected inside, two load-bearing cross plates have two fixed blocks fixedly connected on the outside, multiple fixed blocks have two arc-shaped slot plates fixedly connected on the outside, two arc-shaped slot plates have first arc-shaped gates movably connected on the outside, and one side of the two first arc-shaped gates is provided with a first card slot.

[0009] As a further solution of the utility model: a second arc gate is movably connected inside the two arc slot plates, and two second clamping grooves are arranged on the outer side of the second arc gate, and the two second clamping grooves are symmetrically distributed on both sides of the second arc gate.

[0010] As a further solution of the utility model: two support hinges are fixedly connected to the right side of the load-bearing column, and two rotating shafts are movably connected inside the two support hinges.

[0011] As a further solution of the utility model: the outer sides of the plurality of rotating shafts are fixedly connected with pressure blocks, and the inner sides of the two supporting hinges are movably connected with conical push blocks.

[0012] As a further solution of the utility model: both sides of the inside of the two conical push blocks are movably connected with clamping blocks, and the outer sides of the plurality of clamping blocks are fixedly connected with push rings.

[0013] As a further solution of the utility model: a plurality of bayonet holes are arranged on the outer sides of the two support hinges, and the plurality of bayonet holes are symmetrically distributed on the upper and lower sides of the two support hinges.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. By setting an assembly mechanism, multiple first support arms and second support arms are connected by multiple bolts. At the same time, multiple bolts are used to make the connection between the first support arms and the second support arms more stable and less likely to loosen. Then, the two first card slots and the two second card slots enable the two first arc gates and the second arc gates to be quickly connected to the two arc slot plates, which is convenient for subsequent connection and fixation;

[0017] 2. By setting the support hinge, rotating shaft, pressure block, conical push block, clamping block, push ring and bayonet, the two pressure blocks are pushed and squeezed by the conical push block and rotated to the outside of the support hinge through the two rotating shafts. Multiple clamping blocks can be engaged with the bayonet, so that the conical push block can be quickly fixed. The two pressure blocks are opened outward for preliminary limiting, which is more stable during the subsequent connection process. BRIEF DESCRIPTION OF THE DRAWINGS
