Embodiment Construction

[0032] As shown in the figure, the ductile iron pipe lining equipment is composed of a rotating platform trolley 1, a heating gun 3 and a cloth trolley 2, wherein the rotating platform trolley consists of a frame 101 and a walking wheel set under the frame 101 102 and a plurality of supporting wheel sets 103 arranged on the vehicle frame 101 top. The heating torch 3 is arranged at the position below the vehicle frame 101 corresponding to the support wheel set 103 for preheating the ductile iron pipe 4 . The cloth trolley 2 is arranged on both sides of the vehicle frame 101 respectively. One side of the vehicle frame 101 is provided with a retaining wheel 104 for limiting the axial displacement of the ductile iron pipe 4 . The walking wheel set 102 is composed of a driving wheel set 102a and a passive wheel set 102b. The rotating shaft of the driving wheel set 102a is connected with the output shaft of the motor 105 placed on the vehicle frame 101 through a transmission mechan...

Abstract

The invention relates to lining coating equipment for a ductile cast iron pipe. The lining coating equipment comprises a rotary platform trolley and is characterized in that the rotary platform trolley is composed of a frame, a walking wheel set arranged below the frame and multiple riding wheel sets arranged above the frame, a heating fire gun used for preheating the ductile cast iron pipe is arranged at the position, corresponding to the riding wheel sets, below the frame, and material distributing trolleys are arranged on the two sides of the frame respectively. The lining coating equipment for the ductile cast iron pipe solves the problem that existing lining coating equipment has the defects that a lining is prone to disengagement, production efficiency is low, and the applicability is low; meanwhile, the machining forming time of the lining is shortened, and production efficiency is improved.

Description

technical field [0001] The invention relates to lining equipment for ductile iron pipes. Background technique [0002] Ductile iron pipes are used for water transmission, and the formation of the inner lining usually requires lining equipment, but the existing lining equipment has the following problems: [0003] 1. Since the lining principle of the existing lining equipment is to make the inner lining adhere to the inner wall of the pipe by centrifugal rotation, it is actually a two-layer structure, and the different elongation rates of cement and other lining materials will cause separation. That is to say, it will fall off, and the falling inner lining will pollute the water quality on the one hand, and will block equipment such as metering devices on the other hand. [0004] 2. It takes a long time to form the lining layer and the production efficiency is low. [0005] 3. One lining equipment can usually only work on one ductile iron pipe, and the production efficiency...
