Description

Technical Field

[0001] The utility model relates to the technical field of shield segments, and more specifically, to a vibrating structure for the casting of shield segments. Background Technique

[0002] Shield segments are the main assembled components in shield construction. They are the innermost barrier of the tunnel, bearing the functions of resisting soil pressure, groundwater pressure and some special loads. Shield segments are permanent lining structures, and the casting in the production process of shield segments is particularly important.

[0003] When the vibrating structure for shield segment casting is in use, concrete is conveyed into the mold through the feed pipe and then solidifies in the mold. At this time, the drive motor on the surface of the mold is started to drive the vibrating rod to vibrate the concrete, ensuring uniform vibration inside the concrete, so as to quickly complete the casting work of shield segments.

[0004] In the actual use process of the existing device, since the traditional vibrating structure is attached to the surface of the mold and can only effectively vibrate the concrete on the surface layer of the mold, the efficiency of discharging air bubbles at the bottom is low, which affects the quality of the segments. Therefore, a vibrating structure for shield segment casting is proposed now. Content of the Utility Model

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present utility model are as follows:

[0019] (1) In this solution, two groups of driving motors drive the cam to rotate. Through the mutual cooperation of the cam, connecting plate, and vibrating rod, the vibrating rod penetrates deep into the concrete inside the hole groove to perform effective vibrating operations, avoiding the limitation of traditional vibrating structures that only vibrate the concrete on the surface of the mold. Thus, the vibrating rod can more effectively stimulate the bottom bubbles, improve the discharge efficiency of the bubbles. At the same time, the telescopic rod and spring can adjust and buffer the moving trajectory and force of the vibrating rod to a certain extent, thereby reducing the impact on the mold and concrete during the vibrating process, improving the stability of the vibrating process and the adaptability to different concrete flow states, so as to improve the quality of the shield segment.

[0020] (2) In this solution, the insertion rod is separated from the insertion hole by moving the pulling plate to release the locking of the upper mold and the lower mold. The cylinder drives the upper mold to separate from the lower mold to take out the formed shield segment. Conversely, the upper mold and the lower mold are made to abut against each other, and then the lower mold and the upper mold can be locked by using the insertion rod and the insertion hole to ensure that the mold maintains a stable and precise docking state during subsequent use, avoiding problems such as dislocation and slurry leakage.

[0033] Embodiment 1

[0034] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , this is the first embodiment of the present utility model. This embodiment provides a vibrating structure for shield segment pouring, including a support frame 1 and a support rod 101. The lower surface of the support frame 1 is fixedly connected with the support rod 101. A support plate 102 is fixedly connected between the support rods 101. The upper surface of the support plate 102 is fixedly connected with a lower mold 103. The outer surface of the lower mold 103 is movably connected with an upper mold 104. A vibrating assembly 2 is arranged on the outer surface of the upper mold 104.

[0035] Specifically, the vibrating assembly 2 includes two side plates 201 fixedly installed on the upper surface of the upper mold 104. A driving motor 202 is fixedly connected to the side surfaces of the two side plates 201. A cam 203 is fixedly connected to the output shaft end of the driving motor 202. A connecting plate 204 is abutted against the outer surface of the cam 203. Two vibrating rods 205 are fixedly connected to the lower surface of the connecting plate 204. A vibrating rod 206 is fixedly connected to one end of the vibrating rod 205. Four through holes 207 are formed in the upper mold 104. The vibrating rod 206 is slidably connected to the inside of the through hole 207. Two telescopic rods 208 are fixedly connected between the upper mold 104 and the connecting plate 204. A spring 209 is sleeved on the outer surface of the telescopic rod 208.

[0036] Further, start the two driving motors 202 to drive the cam 203 to rotate. When the cam 203 rotates, it will drive the connecting plate 204 in contact with its surface to move up and down reciprocally. When the connecting plate 204 moves, it will drive the vibrating rod 205 to move up and down. When the vibrating rod 205 moves up and down, it will drive the vibrating rod 206 to move in the preset through hole 207, so that the vibrating rod 206 penetrates into the concrete inside the through hole 207 to perform effective vibrating operations, avoiding the limitation that the traditional vibrating structure only vibrates the concrete on the surface layer of the mold, so that the vibrating rod 206 can more effectively stimulate the bottom bubbles and improve the discharge efficiency of the bubbles, thereby improving the quality of the shield segment. At the same time, when the connecting plate 204 moves, it will drive the telescopic rod 208 and the spring 209 to move, so as to adjust and buffer the movement track and force of the vibrating rod 206 to a certain extent.

[0037] Embodiment 2

[0038] Refer to Figure 1 、 Figure 2 、 Figure 4 And Figure 5 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, the support frame 1 and the support rod 101. The support rod 101 is fixedly connected to the lower surface of the support frame 1. A support plate 102 is fixedly connected between the support rods 101. The lower mold 103 is fixedly connected to the upper surface of the support plate 102. The upper mold 104 is movably connected to the outer surface of the lower mold 103. A mold separation and locking assembly 3 is provided between the upper mold 104 and the lower mold 103.

[0039] Specifically, the mold separation and locking assembly 3 includes two cylinders 301 fixedly installed on the lower surface of the support frame 1. The output shaft end of the cylinder 301 is fixedly connected to the upper surface of the upper mold 104. A plurality of insertion holes 302 are formed in the upper mold 104 and the lower mold 103. An insertion rod 303 is clamped in the insertion hole 302. A pull plate 304 is fixedly connected to one end of the insertion rod 303. An anti-slip sleeve is sleeved on the outer surface of the pull plate 304.

[0040] Further, move the pull plate 304 backward to drive the insertion rod 303 to separate from the corresponding insertion hole 302. In the same way, unlock the locking relationship between the remaining insertion rods 303 and the insertion holes 302 in sequence to complete the unlocking of the upper mold 104 and the lower mold 103. After the unlocking is completed, start the two cylinders 301. When the cylinders 301 move, they will drive the upper mold 104 to move upward, further separating the upper mold 104 from the lower mold 103 to form enough space to take out the formed shield segment. When the upper mold 104 is completely separated from the lower mold 103, the staff can safely take out the formed shield segment from the lower mold 103, and then start the cylinders 301 to drive the upper mold 104 and the lower mold 103 to abut against each other. Through the mutual cooperation of the insertion rod 303 and the insertion hole 302, the upper mold 104 and the lower mold 103 can be locked to ensure the stability of the mold during subsequent use.

[0041] Working principle: During use, place the device at the designated position through the support rod 101 on the lower surface of the support frame 1, and fix the whole device to the ground through the threaded holes and bolts in the mounting plate to improve the overall stability of the device. At this time, connect the concrete to the feed pipe 105, so that the concrete enters the cavity between the upper mold 104 and the lower mold 103 through the feed pipe 105. Subsequently, start the two drive motors 202 to drive the cam 203 to rotate. When the cam 203 rotates, it will drive the connecting plate 204 in contact with its surface to move up and down reciprocally. When the connecting plate 204 moves, it will drive the vibrating rod 205 to move up and down. When the vibrating rod 205 moves up and down, it will drive the vibrating rod 206 to move in the preset hole groove 207, so that the vibrating rod 206 penetrates into the concrete inside the hole groove 207 to carry out effective vibrating operations, avoiding the limitation that the traditional vibrating structure only vibrates the concrete on the surface of the mold, so that the vibrating rod 206 can more effectively stimulate the bubbles at the bottom and improve the discharge efficiency of the bubbles, thereby improving the quality of the shield segment. At the same time, when the connecting plate 204 moves, it will drive the telescopic rod 208 and the spring 209 to move, so as to adjust and buffer the moving track and force of the vibrating rod 206 to a certain extent, thereby reducing the impact on the mold and the concrete during the vibrating process, improving the stability of the vibrating process and the adaptability to different concrete flow states.

[0042] After the shield segment is formed, the worker manually holds the pull plate 304 and moves the pull plate 304 backward to drive the insertion rod 303 to separate from the corresponding insertion hole 302. In the same way, the locking relationship between the remaining insertion rods 303 and the insertion holes 302 is released in sequence to complete the unlocking of the upper mold 104 and the lower mold 103. After the unlocking is completed, two cylinders 301 are started. When the cylinders 301 move, they will drive the upper mold 104 to move upward, further separating the upper mold 104 from the lower mold 103 to form enough space to take out the formed shield segment. When the upper mold 104 is completely separated from the lower mold 103, the worker can safely take out the formed shield segment from the lower mold 103, and then start the cylinder 301 to drive the upper mold 104 and the lower mold 103 to abut against each other. Through the mutual cooperation of the insertion rod 303 and the insertion hole 302, the upper mold 104 and the lower mold 103 can be locked to ensure that the molds maintain a stable and precise docking state during subsequent use, avoiding problems such as misalignment and slurry leakage.

[0043] The above is only the preferred specific implementation mode of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
