Description

Technical Field

[0001] The utility model relates to the field of water conservancy project construction, in particular to an automatic vibrating and tamping slipform device for water conservancy projects. Background Art

[0002] Vibratory slipforms are a type of equipment used in concrete construction, usually for pouring cement components in large-scale water conservancy projects, such as dams and sluice gates. Their main function is to make the concrete more compact in the mold through vibration and oscillation during the concrete pouring process, thereby improving its strength and durability. Existing devices generally require operators to manually adjust their positions during use, and continuously adjust their contact state with the cement surface during the vibratory treatment. The operation intensity is high, and the specific operation requires a lot of manpower costs.

[0003] Therefore, a kind of automatic vibrating and tamping slipform device of hydraulic engineering is now developed in view of the above problems. Utility Model Content

[0006] Preferably, the lifting mechanism includes a connecting frame, the connecting frame is installed in the middle of the lifting seat by bolts, the lower part of the connecting frame is connected to a cylindrical cam, the sliding shaft is connected to a connecting column, and the connecting column is in contact with the top of the cylindrical cam.

[0007] Preferably, an adjustment mechanism is also included, the adjustment mechanism includes a connecting piece, the connecting piece is connected to the right side of the upper part of the vibrator, a limiting column is slidably connected to the connecting piece, the limiting column is clamped with the sliding shaft, and a reset spring is connected between the limiting column and the connecting piece.

[0008] Preferably, the lower sides of the left and right parts of the base are each provided with four moving wheels.

[0009] Preferably, the sliding shaft is an L-shaped structure.

[0010] Preferably, the cylindrical cam is in a structural state where the front side is low and the rear side is high.

[0011] By adopting the above technical solution, the utility model has the following advantages:

[0012] 1. The utility model guides the movement of the connecting column through the cylindrical cam, so that the vibrator can achieve the effect of intermittent reciprocating vibration when vibrating the cement surface after pouring, avoiding the vibrator vibrating the cement all the time, which affects the molding of the cement surface itself. At the same time, manual control by the operator is no longer required, and the operation is simpler.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0019] Example 1

[0020] An automatic vibrating and tamping slipform device for water conservancy projects, such as Figure 1 and Figure 2 As shown, it includes a base 1, and the lower sides of the left and right parts of the base 1 are each provided with four moving wheels. A first servo motor 2 is installed on the upper left side of the base 1, and the output shaft of the first servo motor 2 is set downward. A screw rod 4 is connected to the output shaft of the first servo motor 2. Guide seats 3 are installed on the left and right side walls inside the base 1. The screw rod 4 is rotatably connected to the guide seat 3 on the left side. A lifting seat 5 is slidably arranged between the guide seats 3, and the lifting seat 5 is threadedly connected to the screw rod 4. A second servo motor 6 is installed on the upper middle side of the lifting seat 5, and the output shaft of the second servo motor 6 is set downward. A sliding shaft 7 is slidably arranged on the output shaft of the second servo motor 6, and the sliding shaft 7 is an L-shaped structure. A vibrator 8 is slidably arranged on the front of the sliding shaft 7, and a lifting mechanism 9 for driving the vibrator 8 to reciprocate up and down is arranged on the lifting seat 5.

[0021] like Figure 1-Figure 3 As shown, the lifting mechanism 9 includes a connecting frame 91, and the connecting frame 91 is installed in the middle of the lifting seat 5 by bolts. The lower part of the connecting frame 91 is connected to a cylindrical cam 92, and the cylindrical cam 92 is in a structural state with a low front side and a high rear side. A connecting column 93 is connected to the sliding shaft 7, and the connecting column 93 is in contact with the top of the cylindrical cam 92.

[0022] It should be noted that when vibrating the slipform of the poured water conservancy ditch, the present device can be used to assist the operator in the work. First, the base 1 is moved to the position where the slipform needs to be vibrated, and then the output shaft of the first servo motor 2 is controlled to rotate, so that the screw rod 4 rotates to drive the lifting seat 5 to slide downward along the guide seat 3, so that the vibrator 8 can contact the cement surface, and then the first servo motor 2 is turned off, and then the second servo motor 6 and the vibrator 8 are started. The rotation of the output shaft of the second servo motor 6 will drive the sliding shaft 7 to rotate, so that the vibrator 8 moves in a circle along the cement surface, and vibrates the cement during the circular motion. The bubbles inside the cement are shaken out by the tamping treatment. At the same time, the rotation of the sliding shaft 7 will drive the connecting column 93 to rotate synchronously during this process, so that the connecting column 93 moves along the upper side of the cylindrical cam 92. When the connecting column 93 moves to the upper rear side of the cylindrical cam 92, the sliding shaft 7 will be lifted upward, so that the vibrator 8 is away from the cement surface. Then, when the connecting column 93 moves to the upper front side of the cylindrical cam 92 again, the sliding shaft 7 will move downward, so that the vibrator 8 contacts the cement surface again, achieving the effect of intermittent reciprocating tamping treatment, avoiding the vibrator 8 from tamping the cement all the time, which affects the molding of the cement surface itself.

[0023] Example 2

[0024] On the basis of Example 1, Figure 1-Figure 3As shown, it also includes an adjustment mechanism 10, which includes a connecting piece 101. The connecting piece 101 is connected to the upper right side of the vibrator 8. A limiting column 102 is slidably connected to the connecting piece 101. The limiting column 102 is clamped with the sliding shaft 7, and a reset spring 103 is connected between the limiting column 102 and the connecting piece 101.

[0025] It should be noted that when the cement surface is vibrated, the position of the vibrator 8 can be adjusted as the vibrating time continues to increase, thereby changing the vibration radius and continuously reducing the vibration range to achieve a targeted vibration effect. In specific operations, it is only necessary to pull the limit column 102 to the right so that the limit column 102 is no longer engaged with the sliding shaft 7, and then adjust the position of the vibrator 8 by sliding. After the adjustment is completed, release the limit column 102. Under the action of the reset spring 103, the limit column 102 will slide to the left and reset, and engage with the sliding shaft 7 again to complete the locking limit of the vibrator 8.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
