The trestle triangle support device adjustable in angle is convenient in construction, simple to operate, and capable of building the trestles on the dam facings different in slope by means of the triangle support of the same model number.
Description
Technical field
The utility model relates to a kind of trestle A-frame device of trestle A-frame device, particularly a kind of adjustable angle.
Background technology
In the Hydroelectric Project Construction, high slope, mountain, dam site position is steep, has inconvenient traffic, and for construction needs such as the personnel that guarantee the dam construction phase pass through, material conveyings, at the dam facing higher slice of dam construction bridge is set according to different functional requirements.
For the trestle construction, generally according to the trestle A-frame of dam facing ratio of slope processing corresponding size, to dam bodys such as high dome dams, its dam facing ratio of slope changes greatly conventional method, often needs to process the A-frame of different size.
Summary of the invention
Technical problem to be solved in the utility model be can be on the dam facing of different ratios of slope Bian set up the trestle A-frame device of the adjustable angle of trestle with the A-frame of same model.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of trestle A-frame device of adjustable angle, comprise adjusted part, lower regulating part, A-frame, the first joint angle of described adjusted part and A-frame is flexibly connected; Described lower regulating part is provided with positioning strip, and positioning strip is provided with locating hole, and the second joint angle of A-frame is provided with linkage, and linkage is corresponding with locating hole, can be fixedly connected with.
Described linkage comprises the bolt rod that is arranged on the second joint angle, and an end of bolt rod is fixedly connected with the second joint angle, and the other end can insert locating hole.
Described bolt rod is screw rod, and the bolt rod other end can insert behind the locating hole fastening by nut.
Described bolt rod is the L-type lead screw, and the L-type lead screw can be inserted locating hole, and of L-type lead screw is fastening with electric welding.
Described adjusted part, lower regulating part, A-frame are by channel-section steel or angle steel or steel plate or reinforcing bar machine-shaping.
The trestle A-frame device of the adjustable angle that the utility model provides, first the adjusted part is fixed on the dam during use, again angle one activity of A-frame is fixed on the adjusted part, the rear below of lower regulating part being fixed in the adjusted part, because lower regulating part rectangular is provided with a plurality of holes, can be according to the different postures adjusting A-frame in the corresponding hole that connects of the linkage on the A-frame angle two of the ratio of slope on dam, thereby the one side that so just can keep tripod is the trestle face that the guaranteed level of level, the trestle A-frame device of adjustable angle, for setting up trestle with the A-frame of same model, Bian on the dam facing of different ratios of slope provides technical support, that a kind of construction is simple, the trestle A-frame of being convenient to set up.
