Embodiment Construction
[0026] Such as figure 1 Among them, a drive cylinder 9 is symmetrically installed on both sides of the pump body through the support plate, and the drive cylinder 9 is connected with the plunger 6 through the yoke 23. The two ends of the drive cylinder 9 are provided with proximity switches 5, 12, and the two ends of the pump body are respectively There is a suction and discharge device, and the left suction and discharge chamber end cover 17 is installed by fixing bolts 16 on the outside of the suction and discharge device on the left, and ball valves 18 and 15 are arranged in it; the right suction and discharge chamber is installed on the outside of the suction and discharge device on the right by fixing bolts 26 The end cover 27 is provided with ball valves 19 and 30 therein.
[0027] Such as figure 2 Among them, observation covers 25 and 14 are installed on one side of the ball valves 19 and 30, and pin shafts are arranged on them to limit the position of the ball valves...

The invention discloses a shield tail grouting pump relating to a sludge pump. A drive oil cylinder is connected with a plunger piston in the pump body, and both ends of the pump body are provided with suction devices. Automatic open-close ball valves are arranged in the suction devices to serve as suction valves; each stroke of the plunger piston in the pump body can carry out sludge sucking and grouting, thereby realizing continuous grouting; the plunger piston is provided with an automatic lubricating device so that the abrasion of the plunger piston can be reduced. Aiming at the process characteristics that shield tail slurry is easy to solidify and the pump head and the pipelines need cleaning when a shield machine halts for a long time, the invention designs by taking the pump body of shield tail grouting pump and a slurry storing slot as a whole, so a slurry inlet flow passage is very short and is not easy to block. The end cover of the suction chamber cleaned after the pump body is detached is lighter than 4kg, thereby facilitating the cleaning operation. The performance parameters of the invention completely meet the demands of the shield grouting process of the corresponding specification through an actual shield tail slurry injection experiment, and the production cost is reduced through adopting the design, and the price of the shield tail grouting pump is less 1 / 3 of the prices of like products in the market.
Description
technical field [0001] The invention relates to a mud pump, in particular to a shield tail grouting pump in shield construction. Background technique [0002] Chinese patent "200910045387.1" discloses a shield tunnel synchronous grouting pump. The main working parts and principle of this patented product are to use the telescopic material extraction of the material extraction cylinder, and then use the pressure cylinder in the material extraction cylinder to press the slurry. In principle, the main seals of the product described in this patent are set in the slurry, and the seals are easily stuck and worn by the particles in the slurry; since the seals of the feeding cylinder and the pressing cylinder are all in the silo, After the internal parts or seals are damaged, it is inconvenient to replace and maintain; after use, there is always slurry in the silo, and it is difficult to clean the inner cavity. Contents of the invention [0003] The technical problem to be solved...
