Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction, and in particular relates to a secondary lining trolley concrete longitudinal vibrating device. Background Art

[0002] When concrete is mixed with a concrete mixer and poured into a component, air bubbles must be removed and tamped to compact the concrete and eliminate honeycombing and other surface defects. This increases its strength and ensures the quality of the concrete component. This process of removing air bubbles and tamping the concrete is called concrete vibration.

[0003] The secondary tunnel lining is a ring of concrete lining built inside the primary support, generally serving as a safety reserve. The secondary lining of the arch wall typically utilizes a full-section, integral steel formwork lining trolley, transported by a concrete mixer truck, poured with pumped concrete, and compacted with a vibrator. The head formwork is either steel or wooden. During tunnel concrete pouring, a vibrator is required to vibrate the newly poured concrete. The vibrator used in tunnel secondary lining construction is typically an attached vibrator, consisting of a fixture and the attached vibrator body, which is secured to the formwork via the fixture.

[0004] The vibrating rods currently used in the secondary lining trolleys are inserted at a single point and cannot be moved, and the vibration range is small. The current concrete vibrating rods are ordinary vertically inserted vibrating rods, which can only be vibrated at a fixed point, with a limited vibration range and cannot achieve multi-angle vibration. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a longitudinal vibrating device for concrete on a second lining trolley. Through the longitudinal movement of the vibrating rod, the functions of exhaust and slurry lifting are realized, so that the concrete molding surface is smoother, and the problem that the current ordinary vertically inserted vibrating rod can only vibrate at a fixed point and has a limited vibration range is solved, thereby enhancing the density of the longitudinal pouring of the top concrete.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A secondary lining trolley concrete longitudinal vibration device comprises a longitudinal pouring trolley, a longitudinal vibrating rod longitudinal movement trolley is installed on the top of the longitudinal pouring trolley, the longitudinal vibrating rod longitudinal movement trolley moves on the longitudinal pouring trolley through a sliding track, and a vibrating rod is installed above the longitudinal vibrating rod longitudinal movement trolley; a blocking template is provided on the top of the secondary lining trolley, and a guide hole is opened in the blocking template, and the vibrating rod is longitudinally inserted into the blocking template through the guide hole for vibration.

[0008] Specifically, the vibrating rod is provided with front and rear lifting fulcrums, the front lifting fulcrum is arranged on the left end of the longitudinal pouring trolley, and the rear lifting fulcrum is arranged on the longitudinal vibrating rod longitudinal movement trolley.

[0009] Specifically, a sliding roller is provided on the front lifting fulcrum, and the sliding roller is slidably connected to the vibrating rod;

[0010] Specifically, the rear lifting fulcrum is detachably connected to the vibrating rod.

[0011] Specifically, the longitudinal vibrator longitudinal movement trolley is installed with a driving motor to drive the longitudinal vibrator longitudinal movement trolley to move on the sliding track.

[0012] The utility model has the following advantages:

[0013] The utility model provides a longitudinal vibrating device for concrete of a secondary lining trolley. Conventional vertical insertion vibrators can only vibrate at a fixed point and have a limited vibration range. The longitudinal insertion vibrator of the utility model can be dynamically moved longitudinally for vibration. The concrete of the entire longitudinal length of the top arch of the trolley can be vibrated without dead angles. The quality of the vibrated concrete is uniform and dense. The longitudinal movement of the vibrating rod can realize the functions of exhausting and raising slurry, making the concrete molding surface smoother. BRIEF DESCRIPTION OF THE DRAWINGS
