Technical Field
[0001] The utility model relates to the technical field of grouting equipment, in particular to a fixed gun head for PC grouting. Background Art
[0002] During the construction process, there are often a large number of PC grouting operations, and these PC grouting operations often require workers to use a grouting machine and a handheld grouting gun head to operate.
[0003] After searching, the Chinese patent with publication number CN220058882U discloses a manually controlled sleeve grouting machine gun head, including a button, a reset spring, a force transmission rod, a movable baffle, a fixed baffle and a grouting machine gun head body; the fixed baffle is fixedly arranged in the grouting machine gun head body, and a first through hole is formed on the fixed baffle; the reset spring is installed on the top of the grouting machine gun head body, and the button is installed on the top of the reset spring. One end of the force transmission rod passes through the top of the grouting machine gun head body and the reset spring and is fixedly connected to the button, so that the other end of the force transmission rod can be elastically arranged in the grouting machine gun head body and connected to the movable baffle; a second through hole is formed on the movable baffle, and the movable baffle is movably fitted on the fixed baffle, and the first through hole and the second through hole coincide or partially coincide or are staggered.
[0004] Based on the above search and combined with existing technology findings;
[0005] Although the above patent can improve the grouting quality to a certain extent, it is easy to cause leakage during grouting in shallow grouting ports. In addition, under the action of large grouting pressure, the grouting gun head is likely to fall off, thereby affecting subsequent use. Therefore, there are certain limitations. Utility Model Content
[0006] In order to solve the above technical problems, the utility model proposes a fixed gun head for PC grouting. The use of this device can prevent leakage during the grouting process, and at the same time prevent excessive pressure during the grouting process, which causes the grouting gun head to be pushed out of the grouting hole and cause unknown effects.
[0007] The technical solution to achieve the purpose of the utility model is: a fixed gun head for PC grouting, including a grouting gun head, a plurality of mounting blocks fixedly installed on the outer peripheral wall of the grouting gun head, a support ring fixedly installed between the plurality of mounting blocks, and also including a fixing component.
[0008] The fixing assembly includes a plurality of fan-shaped semicircular pieces rotatably mounted on a support ring.
[0009] Preferably, a pair of fan-shaped semicircular pieces 2 are fixedly installed between each two adjacent fan-shaped semicircular pieces 1, each fan-shaped semicircular piece 2 is rotatably installed on the support ring, and a pair of coil springs are fixedly installed between the interior of each fan-shaped semicircular piece 1 and the fan-shaped semicircular piece 2 and the support ring.
[0010] Preferably, a sliding groove 1 and a sliding groove 2 are respectively provided on the sector-shaped semicircular piece 1 and the sector-shaped semicircular piece 2, and sliding blocks are slidably installed inside the sliding groove 1 and the sliding groove 2.
[0011] Preferably, connecting rings are fixedly installed inside the plurality of sliding blocks, and rubber adjusting rings are fixedly installed between the plurality of connecting rings.
[0012] Preferably, an electric telescopic rod is fixedly mounted on the inner side wall of the sliding groove 1, and the telescopic end of the electric telescopic rod is fixedly connected to the sliding block.
[0013] Compared with the prior art, the present invention has the following significant advantages:
[0014] First, the utility model provides a support ring on the grouting gun head to provide support for the fixed component, and utilizes the rotatably installed fan-shaped semicircular piece 1 and fan-shaped semicircular piece 2 to fit on the surface of the grouting gun head when not in use. When grouting operation is in progress, under the action of the electric telescopic rod, the provided sliding block moves with the rubber adjusting ring. When the rubber adjusting ring moves, it gradually loosens the restraint on the fan-shaped semicircular piece 1 and fan-shaped semicircular piece 2. Under the action of the coil spring, the fan-shaped semicircular piece 1 and fan-shaped semicircular piece 2 are opened and stuck in the grouting port, thereby preventing leakage during the grouting process. It can also provide support for the grouting gun head to prevent excessive pressure during the grouting process, which causes the grouting gun head to be pushed out and affects use.
[0015] Secondly: The utility model is small in size and light in weight, safe and reliable, and can be used to modify the existing grouting gun head. It can prevent leakage of grouting holes and spraying of the gun head during the grouting process. At the same time, it can also reduce the labor intensity of workers to a certain extent. It is suitable for different working environments and can be put away after use and wait for the next use.
[0016] The search patent solves the problem that although the grouting quality can be improved to a certain extent, leakage is prone to occur during grouting in shallow grouting openings. In addition, under the action of large grouting pressure, the grouting gun head is prone to fall off, thus affecting subsequent use. BRIEF DESCRIPTION OF THE DRAWINGS
