Embodiment 1

[0028] In order to solve the technical problem of the above-mentioned transportation difficulties, the present invention figure 2 As shown, the traditional integral support arm base is cut into two sections up and down along the ray direction of the fulcrum of rotation; or cut into more than three sections along the ray direction of the fulcrum of rotation to form multiple smaller parts, each smaller part It is transported by one vehicle to solve the problems of overweight, overwidth and overheight during transportation. In order to facilitate on-site assembly, the cut surface of each component is equipped with a connecting plate, and the connecting plate is provided with a number of connecting holes for connection. When the components arrive at the construction site, bolts pass through the connecting holes to connect each component. Assembles into an arm base.

Embodiment 2

[0034] When the arc gate is particularly large, multiple sets of arms are required to support the door leaf, and the corresponding arm bases are also particularly large. Figure 4 Shown is a schematic diagram of a three-arm arc gate formed by adopting the technical solution of the present invention. Figure 4 The partially enlarged part in is a schematic diagram of the three-arm detachable arm base of the present invention. Figure 5 yes Figure 4 Schematic breakdown of the structure.

[0035] Depend on Figure 4 and Figure 5 It can be seen that the three-arm detachable arm base is composed of an upper section 1 of the arm base and a lower section 2 of the arm base, and is located between the upper section 1 of the arm base and the lower section 2 of the arm base. The middle section 14 of the support arm base is assembled, and the upper section, the middle section and the lower section of the support arm base are all box-shaped structures, and the two box-shaped structure...

Embodiment 3

[0039] When cutting the base of the arm, it is not necessary to take the form of equal division. It is also possible to cut the support arm base into sections of different sizes according to the specific conditions of the project. Such as Figure 6 as shown, Figure 6 is a three-arm detachable arm base, Figure 6 Cutting line 16 in will cut the base of the arm into two parts of unequal size. The upper section 1 of the support arm base is smaller than the lower section 2 of the support arm base, and the upper section 1 of the support arm base is only connected with one group of support arms; while the lower section 2 of the support arm base is connected with two groups of support arms. In order to improve the strength of the lower section 2 of the support arm base, a Y-shaped middle web 15 can be added in the lower section 2 of the support arm base, and two front end plates 11 are welded at different angles to cooperate with the door leaves of the arc gate.

Abstract

The invention discloses a method for solving the transportation difficulty problem of a huge support arm base and the detachable support arm base. A traditional integral support arm base is sectioned into two sections or more than two sections of small parts in the radial direction of a rotating fulcrum, and each small part is transported by one vehicle; the section cutting plane of each small part is provided with an inter-section end face connecting plate, and when the parts are transported to a construction site, all the parts are connected together to be assembled into the support arm base by enabling bolts to penetrate through connecting holes. According to the method, by sectioning the integral support arm base into the small parts, the transportation weight can be reduced, the size of the parts is decreased, and the technical problem that the traditional integral support arm base is difficult to transport is solved. On the site, the bolts are adopted for fixed connection without needing welding, and therefore stress generated in welding can be reduced. All the parts are provided with operation holes, and therefore the assembly difficulty of the bolts can be reduced. A symmetrical structure is beneficial for transmitting force and reducing deformation of the support arm base and also beneficial for uniform force transmitting of the bolts.

Description

technical field [0001] The invention relates to a method for solving the transportation difficulty of a super large support arm base and a detachable support arm base, which belong to the technical field of arc door manufacturing in hydropower engineering. Background technique [0002] The traditional arm base is usually an integral type, which does not restrict engineering for gates with conventional orifice sizes or areas with superior transportation conditions. Generally speaking, there are many problems in the transportation process of the integral super large arm base. For example, in the Dadu River Zhentouba Class I hydropower station project in Sichuan, the size of the working arc door of the flood discharge gate is 8m×16m (width×height), and the size of the arm base is 4.73m×1.7m×3.72m (length×width× High), this super-large arm base exceeds the weight of road transportation in remote areas of Sichuan, Yunnan and Tibet, and its dimensions far exceed the height and wi...
