Description
Technical Field
The utility model relates to a detection device, especially a cement grouting quality detection device behind non-excavation pipe worker.
Background
After the horizontal directional drilling pipe laying power pipeline is subjected to reaming construction, a reaming borehole with the diameter 1.2-1.6 times of the diameter of the pipeline is formed underground. When the annular volume is large, after the pipeline is pulled back, if the outside annular space between the borehole and the pipeline is not filled and consolidated in time, hidden troubles may be generated on the structure and strength of the underground pipeline, and the structure and stability of the buildings or roads which cover the earth surface. In order to avoid hidden danger of settlement on underground pipelines and surface buildings, after grouting operation is completed after trenchless construction, the consolidation quality of the outer annular space of the pipe is tested, qualitative and quantitative evaluation is carried out on the shape and the structure of the pipe, the grouting in place condition, the annular consolidation condition, the consolidation quality and the like, the service life of the power pipeline is ensured and prolonged, and the long-term serviceability and the laying benefit of the pipeline are improved, so that the method has extremely important significance. At present, the detection gel is coated on a position to be detected and is carried out by using a detection probe, but no grouting quality detection equipment exists in the laid pipeline at home. The detection is performed manually, and the operation is very difficult to perform manually when the detection is performed in a narrow pipeline or a pipeline in a severe environment, so that an apparatus is urgently needed to complete the detection.

Detailed Description
A cement slip casting quality detection device behind non-excavation pipeline worker in picture includes base 1, motor 2, test probe 3, its characterized in that: the gel detection device is characterized in that a motor is arranged on a base, a detection gel storage cabin 4 is arranged on the base, a rotating shaft of the motor is connected with a cam driving shaft 5, four driving cams 6 are arranged on the cam driving shaft, each driving cam corresponds to one connecting rod group 7, one connecting rod group is connected with a detection gel suction pump 8, one connecting rod group is connected with one detection probe 3, the other two connecting rod groups are connected with probe protection covers 9, the detection probes are located in the probe protection covers, an outlet of a hose 10 is arranged in each probe protection cover, an inlet of the hose is connected with the detection gel suction pump, and the detection gel suction pump is connected with the detection gel storage cabin 4 through a one-way valve 11. The connecting rod group is a door-shaped frame, two sides of the connecting rod group are provided with straight rods 12, the straight rods are positioned in connecting rod sleeves 13 on the base, limiting springs 14 are sleeved on the straight rods, and cross rods 15 of the connecting rod group are opposite to the driving cams. The probe protection cover is composed of an upper part and a lower part, and the middle parts are connected by a spring 16.
In practical operation, the detection device of the utility model is installed on an inner diameter detection crawler 20, and then the detection device is dragged by a traction rope or moves in a pipeline by a self-walking crawling device, when the detection device moves to a position to be detected, a motor rotates, two groups of connecting rods for connecting a probe protection cover are jacked by a cam, pushed up to the highest position by the probe protection cover and contacted with the pipe wall, and the probe protection cover can be ensured to be close to the detected pipe wall due to the existence of a spring; at the moment, the connecting rod group connected with the detection gel suction pump is pushed by the cam, the suction piston is pushed forwards, and the detection gel in the detection gel suction pump cabin is injected into the probe protective cover, so that the tube wall in the range of the probe protective cover is coated with the detection gel; the subsequent suction piston is pulled back. Under the action of the one-way valve and the one-way valve in the hose, the detection gel in the detection gel storage cabin is sucked into the detection gel suction pump cabin for the next detection; finally, a group of connecting rods at the bottom of the detection probe are pushed to the highest by the cam and are in contact with the pipe wall, and monitoring is started and kept for 3 seconds; detecting the probe withdrawal; the probe cover is retracted. This is the end of a cycle.
By adjusting the shape of each cam and the rotating speed of the motor, the detection probe, the probe protective cover and the suction piston of the detection gel suction pump can be controlled to move in sequence.
