Specific embodiments

[0022] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0023] As Figure 1 and Figure 2 shown, in an embodiment of the present invention, a rotatable insert type vibrating device for the arch top of a tunnel lining includes a cylinder body 1, a vibrator and a rotary power member; a movable plate 5, a threaded rod 6 and a rotating rod 7 are arranged in the cylinder body 1, the movable plate 5 is slidably installed inside the cylinder body 1, the threaded rod 6 is rotatably installed in the cylinder body 1 and forms a screw pair transmission with the movable plate 5, the rotating rod 7 is rotatably installed in the cylinder body 1 and is slidably connected with the rotating ring 12 on the movable plate 5; the rotary power member is installed on the cylinder body 1, the driving shaft of the rotary power member is in transmission connection with the threaded rod 6 through the intermittent transmission assembly 13, and the threaded rod 6 is driven by the rotary power member to rotate intermittently, the driving shaft of the rotary power member is in transmission connection with the rotating rod 7 through the transmission member I, and the rotating rod 7 is driven by the rotary power member to rotate; the vibrator includes a cylinder block 8 and a vibrating rod 9, the cylinder block 8 is rotatably installed on the movable plate 5, the vibrating rod 9 is installed at the vibrating end of the cylinder block 8, and the cylinder block 8 is in transmission connection with the rotating ring 12 through the transmission member II, and the cylinder block 8 is driven to rotate by the rotating rod 7;

[0024] When the present invention is in use, construction workers can move the cylinder body 1, place the cylinder body 1 on the lining steel bar support, and adjust the vibrating position by moving the cylinder body 1;

[0025] When performing vibration processing, the rotary power component is started. Through the rotation of the rotary power component and the transmission of the intermittent transmission component 13, the threaded rod 6 is driven to rotate periodically and intermittently. When the threaded rod 6 rotates, the movable plate 5 is driven to move, driving the vibrator to move, and adjusting the vibration position of the vibrating rod 9 in the concrete. When the threaded rod 6 stops rotating, the vibrating rod 9 vibrates the concrete at this time, removing the air bubbles in the concrete and improving the density of the concrete, thus replacing manual adjustment of the insertion depth of the vibrating rod 9 and maintaining the vibration state, reducing the labor intensity of construction workers;

[0026] At the same time, when the rotary power component rotates, the rotating rod 7 can be synchronously driven to rotate, and then the rotating ring 12 and the cylinder body 8 of the vibrator are driven to rotate, so that the vibrating rod 9 rotates in the concrete during the vibration process, increasing the vibration range and further improving the vibration efficiency;

[0027] The rotary power component is preferably a power motor 2. In the present invention, only one set of power motor 2 is selected to cooperate with the transmission components, improving the utilization efficiency of the power motor 2.

[0028] As Figure 3 shown, in the embodiment of the present invention, the intermittent transmission component 13 includes an incomplete gear I 1301 and an incomplete gear II 1302. The incomplete gear I 1301 is coaxially installed on the output shaft of the rotary power component, and the incomplete gear II 1302 is coaxially installed on the threaded rod 6. The smooth surface side of the incomplete gear I 1301 is slidably connected in the groove provided on the smooth surface side of the incomplete gear II 1302. The end faces of the incomplete gear I 1301 and the incomplete gear II 1302 are respectively provided with a positioning post 1303 and a positioning rod 1304 for positioning and cooperation. The incomplete gear II 1302 is driven to rotate intermittently by the incomplete gear I 1301. The incomplete gear I 1301 is driven by the power motor 2 to always maintain uniform rotation. When the smooth surface of the incomplete gear I 1301 is slidably connected to the groove of the incomplete gear II 1302, the incomplete gear II 1302 is limited by the groove and remains fixed at this time. At the same time, when the positioning post 1303 on the incomplete gear I 1301 contacts the positioning rod 1304 on the incomplete gear II 1302, the positioning rod 1304 and the incomplete gear II 1302 are driven to rotate by the positioning post 1303 pressing the positioning rod 1304. At this time, the smooth surface of the incomplete gear I 1301 is separated from the groove of the incomplete gear II 1302, and the tooth surface of the incomplete gear I 1301 is in contact with and meshes with the tooth surface of the incomplete gear II 1302. At this time, the incomplete gear II 1302 is driven to rotate by the incomplete gear I 1301, that is, the threaded rod 6 is driven to rotate;

[0029] In the present invention, the specification of the incomplete gear I 1301 is larger than that of the incomplete gear II 1302, so that within a certain period, the time when the incomplete gear II 1302 is stationary is longer than its rotation time, ensuring that the vibrating rod 9 can vibrate stably in the concrete layer at the same depth for a period of time;

[0030] Of course, in actual design, other components with intermittent transmission capabilities can also be selected, such as a Maltese wheel intermittent transmission structure, etc.

[0031] As Figure 2 shown, in the embodiment of the present invention, the movable plate 5 is slidably connected to the inner wall of the cylinder 1. A sliding groove for slidably connecting the movable plate 5 is provided on the inner wall of the cylinder 1. By setting the sliding groove, the stability of the movable plate 5 during sliding is improved;

[0032] At the same time, an internally threaded tube 501 for drivingly connecting the threaded rod 6 is fixedly installed on the movable plate 5. When the threaded rod 6 is driven to rotate by the incomplete gear II 1302, the movable plate 5 is driven to move through the transmission of the internally threaded tube 501.

[0033] As Figure 4 and Figure 5 shown, in the embodiment of the present invention, the rotating ring 12 is rotatably connected to the installation hole provided on the movable plate 5, and when the rotating ring 12 rotates, it does not disengage from the movable plate 5. A plurality of connecting grooves 1201 are arranged on the inner wall of the rotating ring 12 in a direction parallel to the axis. The plurality of connecting grooves 1201 are slidably connected to a plurality of fixing strips 701 correspondingly arranged on the outer wall of the rotating rod 7. In the present invention, when the movable plate 5 moves, the corresponding rotating ring 12 slides in a direction parallel to the axis of the rotating rod 7, and at the same time, the rotating rod 7 can drive the rotating ring 12 to rotate coaxially;

[0034] Among them, as Figure 2 shown, the transmission member I and the transmission member II are respectively the first transmission belt 10 and the second transmission belt 11. When the power motor 2 starts to rotate, through the transmission of the first transmission belt 10, the rotating rod 7 and the rotating ring 12 connected to the rotating rod 7 are driven to rotate, and then through the transmission of the second transmission belt 11, the cylinder body 8 of the vibrator is driven to rotate, thereby driving the vibrating rod 9 to rotate;

[0035] Of course, the transmission member I and the transmission member II can also use other components with transmission capabilities, such as a transmission chain, etc. In the present invention, the bearings used for the rotational connection of the components are set as the defaults of those skilled in the art, and the present invention does not describe them in detail.

[0036] As Figure 1As shown in the figure, in the embodiment of the present invention, a guiding cylinder 4 is provided on one end face of the cylinder body 1 different from the side where the rotational power member is installed. The vibrating rod 9 passes through the guiding cylinder 4 and extends out of the cylinder body 1, and the swinging range of the vibrating rod 9 is limited by the guiding cylinder 4.

[0037] As Figure 1 shown in the figure, in the embodiment of the present invention, multiple groups of handles 3 are provided on the outer side of the cylinder body 1, and construction workers can assist in carrying the cylinder body 1 by holding the handles 3.

[0038] In summary, in the present invention, the rotational power member rotates, and cooperates with the intermittent transmission assembly 13 to drive the threaded rod 6 to rotate periodically and intermittently, and intermittently adjusts the vibrating position of the vibrating rod 9 in the concrete. When the threaded rod 6 stops rotating, at this time, the vibrating rod 9 vibrates the concrete to remove the air bubbles in the concrete and improve the density of the concrete, thereby replacing manual adjustment of the insertion depth of the vibrating rod 9 and maintaining the vibrating state, reducing the labor intensity of construction workers. At the same time, the rotational power member can synchronously drive the rotating rod 7 to rotate, and further drive the cylinder body 8 of the vibrator to rotate, so that the vibrating rod 9 rotates in the concrete during the vibration process, improving the vibration range and vibration efficiency.

[0039] The above has described the preferred embodiments of the present invention in detail, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
