Abstract
The utility model relates to a self-adaptive caliber riding wheel for a pipeline. The self-adaptive caliber riding wheel for the pipeline comprises a base, side links, connecting rods and a casing pipe, wherein lower ends of two side links are respectively hinged with two sides of the base; the top of one side link is respectively hinged with the top of one connecting rod; lower ends of the two connecting rods are hinged with the same expansion link; a steel tube is fixed in the middle of the base; holes are formed on the steel tube and the expansion link; the expansion link is sleeved in the steel tube; and a plug passes through the holes on the steel tube and the expansion link so as to fix the expansion link. The self-adaptive caliber riding wheel for the pipeline is simple in structure, convenient in adjustment and suitable for the pipelines with different calibers; the use ratio of the self-adaptive caliber riding wheel for the pipeline is increased; and the construction cost is lowered.
Description
Technical field
The utility model relates to a kind of self adaptation caliber pipeline support roller.
Background technology
At present; Used pipeline support roller in the pipeline rehabilitation engineering only adapts to the pipeline of single specification, if the pipeline of multiple different size is arranged in the construction; Need in engineering construction, make multiple different pipeline support roller according to different calibers; Take substantial contribution, make pipeline support roller service efficiency low, the pipeline support roller deposit occupied ground.
Summary of the invention
It is a kind of simple in structure that the purpose of the utility model is to provide, and can adapt to the self adaptation caliber pipeline support roller of different tube diameters pipeline.
The technical scheme of the utility model is:
Self adaptation caliber pipeline support roller comprises base, side link, connecting rod and sleeve pipe, and casing pipe sleeve is on connecting rod; The lower end of two side links is articulated and connected with the both sides of base respectively, and the top of the top of a side link and a connecting rod is articulated and connected, and the lower end of two connecting rods and same expansion link are articulated and connected; Steel pipe is fixed in the middle of the base; Have the hole on steel pipe and the expansion link, expansion link is enclosed within the steel pipe, and the hole that latch passes steel pipe and expansion link is expansion link fixedly.
Concrete, side link is connected with bearing pin with base.
Concrete, side link is connected with bearing pin with connecting rod.
Concrete, connecting rod is connected with bearing pin with expansion link.
During work, base fixes on the ground, and pipeline is placed on the sleeve pipe of self adaptation caliber pipeline support roller; Expansion link can move up and down and utilize latch to fix; Drivening rod and side link are opened outward or are interior tight, make the utility model can adapt to the pipeline of different tube diameters, promote pipeline; Sleeve pipe rolls, and makes things convenient for pipeline to advance.
The utility model is simple in structure, and is easy to adjust, can adapt to the pipeline of different tube diameters, and range of use is wide, and Occupation coefficient is high, has reduced construction cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 base, 2 side links, 3 connecting rods, 4 sleeve pipes, 5 steel pipes, 6 expansion links
7 latches, 8 bearing pins.
The specific embodiment
Self adaptation caliber pipeline support roller; Comprise base 1, side link 2, connecting rod 3 and sleeve pipe 4; The lower end of two side links 2 is articulated and connected with bearing pin 8 with the both sides of base 1 respectively, and the top of the top of side link 2 and connecting rod 3 is articulated and connected with bearing pin 8, and the lower end of two connecting rods 3 and same expansion link 6 usefulness bearing pins 8 are articulated and connected; Steel pipe 5 is fixed in the middle of the base 1; Have the hole on steel pipe 5 and the expansion link 6, the part of expansion link 6 is enclosed within the steel pipe 5, and the hole that latch 8 passes steel pipe 5 and expansion link 6 is expansion link 6 fixedly.
Should be noted that at last: above embodiment only in order to the explanation the utility model technical scheme but not to its restriction; Although with reference to preferred embodiment the utility model has been carried out detailed explanation, the those of ordinary skill in affiliated field is to be understood that: still can make amendment to the specific embodiment of the utility model perhaps is equal to replacement to the part technical characterictic; And not breaking away from the spirit of the utility model technical scheme, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
