Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grouting pumps, in particular to a grouting pump with an injection pipe fixing guide structure. Background Art
[0002] A grouting pump is a mechanical device specifically designed to transport various slurry materials. It is widely used in construction, mining, tunneling, and geological engineering, where it is primarily used to reinforce soil or rock structures, fill voids, and prevent groundwater infiltration. This device works by generating pressure through hydraulic or electric drive, delivering a pre-prepared slurry (typically a mixture of cement, water, sand, and other additives) to a designated location.
[0003] When a building foundation needs to be reinforced, a common practice is to first drill a hole at a predetermined location and then insert a grouting pipe into the hole for grouting. When the grouting pipe is inserted into the hole and grouting begins, the slurry enters the gap between the strata under high pressure through the grouting pipe. During this process, the grouting pipe will experience a certain degree of vibration. This vibration is mainly caused by the fluidity of the slurry and the injection pressure. The unstable vibration of the grouting pipe will make the injection of the slurry difficult, resulting in the slurry failing to fully fill the predetermined space, forming cavities or unreinforced areas, which will directly affect the overall effect of the foundation reinforcement. How to invent a grouting pump with a fixed guide structure for the grouting pipe to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0023] Reference Figure 3-Figure 5 The fixed guide assembly includes a stabilizing sleeve 14 and a guide tube 15. The side wall of the stabilizing sleeve 14 is provided with a plurality of cylindrical holes equidistantly arranged around the circumference. A fixing pin 20 is slidably connected inside the cylindrical hole. The end of the guide tube 15 is fixedly connected to a tapered tube 16, the end of the tapered tube 16 is fixedly connected to a threaded tube 17, the end of the threaded tube 17 is fixedly connected to a locking tube 18, and the end of the locking tube 18 is fixedly connected to a sealing tube 19; one end of the fixing pin 20 is tapered and the other end is arc-shaped. The inner side wall of the stabilizing sleeve 14 is engaged with the threaded tube 17 through a first thread; the locking A plurality of semicircular grooves 23 are provided on the tube 18, and the plurality of semicircular grooves 23 are arranged corresponding to the positions of the plurality of sliding beads 12; the stabilizing sleeve 14 is inserted into the hole, and the locking tube 18 is driven to rotate by rotating the locking tube 10, and the guide tube 15 and the tapered tube 16 are pushed deeper into the hole through the engagement of the threaded tube 17 with the stabilizing sleeve 14, and the tapered tube 16 squeezes the plurality of fixing pins 20, so that the fixing pins 20 squeeze the hole wall in the building foundation, thereby fixing the stabilizing sleeve 14, so that the injection pipe is more stably fixed in the building foundation, and the problem of unstable grouting effect caused by vibration during grouting is prevented.
[0024] The working principle of the grouting pump with a grouting tube fixing guide structure is as follows: the locking sleeve 11 is pushed toward the spiral lock nut 9, so that the sliding ball 12 loses the obstruction of the inclined platform 22, and the locking tube 18 is inserted into the locking tube 10.

In the process of the inclined surface on the tapered tube 16 pushing into the hole, multiple fixing pins 20 are squeezed to extend outward from the stabilizing sleeve 14. The tapered ends of the fixing pins 20 are squeezed by the hole wall in the building foundation to fix the stabilizing sleeve 14; by pushing the locking sleeve 11 toward the direction of the spiral lock nut 9, the sliding ball 12 loses the limit of the locking sleeve 11 and slides out of the semicircular groove 23 under the action of the thrust, thereby completing the separation of the locking tube 10 and the locking tube 18.
[0025] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
