Embodiment 2

[0054] The difference between Embodiment 2 and Embodiment 1 is that the expansion mechanism includes a left screw rod 12 hinged inside the handle of the left pincer arm 11 and a right screw rod 14 hinged inside the handle of the right pincer arm 25. The left screw rod It is connected with the right screw rod through the threaded sleeve 13, and the threaded sleeve is provided with a through hole, which is convenient for the insertion of the plunger. Turning the plunger clockwise drives the handles of the two clamp arms to move inward, and the distance between the rectangular clips decreases. Turn it counterclockwise The plunger drives the handles of the two clamp arms to move to the outside, and the distance between the two rectangular clips 22 increases to tighten the connecting column.

Abstract

The invention discloses a push-open type convenient-to-operate dam bag gap maintenance device which comprises an inner bottom seat and a connection column arranged on the inner bottom seat; the connection column is sleeved with a pressing plate; a fastener for pressing the pressing plate is arranged on the connection column; a clamping operating mechanism is arranged in the connection column and comprises a left forceps arm and a right forceps arm which are hinged; and rectangular clamping pieces clamped into a through hole in the connection column are arranged at the upper parts of the left forceps arm and the right forceps arm. The push-open type convenient-to-operate dam bag gap maintenance device saves labor and time and is low in maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of rubber dam engineering and construction, and in particular relates to a dam bag gap maintenance device of an expandable type and easy to operate. Background technique [0002] The rubber dam project is a new type of water-retaining structure. Because of its novel structure, obvious economic benefits, and convenient management, it is widely used in many fields such as flood control, water-retaining irrigation, urban and rural water supply, hydropower generation, and beautification of the environment. The rubber dam bag is the main body of the project operation. Due to its thin-walled flexible structure, the operation may encounter strong impact, friction, beating of the flood, collision of floating objects downstream on the dam bag, sharp objects piercing, cutting and other damages. After the rubber dam bag is damaged, there are mainly two kinds of cracks: one is the longitudinal crack, which is smaller; t...
