DETAILED DESCRIPTION

[0040] The present application will be further described in detail below in combination with all the drawings.

[0041] Embodiment one

[0042] The present application discloses a movable attached concrete vibrator, referring to Figure 1 , including track 1, workbench 2 and vibrating rod 3. The vibrating rod 3 is arranged on the workbench 2, and the workbench 2 reciprocates along the length direction of the track 1 to vibrate the concrete.

[0043] With reference to Figure 1 , the track 1 is provided with two parallel tracks, and two sliding blocks 11 are arranged on each track 1 and reciprocate along the length direction of the track 1. A hydraulic rod 12 is vertically arranged above the sliding block 11, and the upper end of the hydraulic rod 12 is fixedly connected with the lower surface of the workbench 2. The four sliding blocks 11 are respectively located at the four corners of the workbench 2. The hydraulic rod 12 moves up and down to drive the workbench 2 to move up and down, thereby adjusting the depth of the vibrating rod 3 inserted into the concrete, so as to vibrate the concrete at different depths and ensure the vibrating effect.

[0044] With reference to Figure 1 , a plurality of bidirectional screws 21 are rotatably connected to the workbench 2, the bidirectional screws 21 are sequentially fixedly connected end to end, and all the bidirectional screws 21 are coaxial and fixedly connected. The axis direction of the bidirectional screw 21 is perpendicular to the length direction of the track 1. Two moving seats 22 are installed on each bidirectional screw 21, and one vibrating rod 3 is connected to each moving seat 22. When the bidirectional screw 21 rotates, the two moving seats 22 move towards or away from each other. The bidirectional screw 21 rotates to drive the vibrating rod 3 to move, thereby adjusting the position of the vibrating rod 3 to increase the vibrating range of the vibrating rod 3 and ensure the vibrating effect.

[0045] With reference to Figure 1 and Figure 2 , a fixed table 8 is fixedly connected to the moving seat 22, a fixed seat 5 is rotatably connected to the fixed table 8, a fixed ball 51 is rotatably connected to the center of the fixed seat 5, and the diameter of the fixed ball 51 is greater than the height of the fixed seat 5. A fixed groove 81 for accommodating the fixed seat 5 is formed in the fixed table 8, and the bottom of the fixed groove 81 is open to the position opposite to the fixed ball 51. A fixed hole 511 penetrating the center of the ball is formed in the center of the fixed ball 51, and a clamping mechanism is arranged in the fixed hole 511. The vibrating rod 3 is arranged in the fixed hole 511, the clamping mechanism clamps the vibrating rod 3, and the lower end of the vibrating rod 3 penetrates out of the bottom of the fixed groove 81.

[0046] With reference to Figure 1 and Figure 2 , the fixed seat 5 clamps the vibrating rod 3 through the fixed ball 51, and the fixed ball 51 can rotate on the fixed seat 5, so that the vibrating rod 3 is inclined on the fixed seat 5, and the axis of the vibrating rod 3 intersects with the center line of the fixed seat 5. When the fixed seat 5 rotates around its center line, the vibrating rod 3 synchronously rotates around the center line of the fixed seat 5, and at this time, the lower end of the vibrating rod 3 makes a circular motion in the concrete, thereby further increasing the vibrating range of the vibrating rod 3.

[0047] With reference to Figure 1 and Figure 2The fixed base 5 is provided with a fixed motor 82, and the output shaft of the fixed motor 82 is connected with a fixed gear 83. The outer wall of the fixed base 5 is provided with a gear groove which is engaged with the fixed gear 83. When the fixed motor 82 is started, the fixed gear 83 is engaged with the gear groove to drive the fixed base 5 to rotate.

[0048] With reference to Figure 1 and Figure 2 The moving base 22 is fixed with a clamping base 6 which is located below the fixed base 8. The clamping base 6 is provided with a circular clamping groove 61, and a cylindrical clamping block 4 is rotatably connected in the clamping groove 61. The upper surface of the clamping block 4 is fixedly connected with the fixed base 5 through a connecting rod 43. The bottom of the clamping base 6 is provided with an avoiding hole which is communicated with the clamping groove 61 and has a smaller diameter than the clamping groove 61.

[0049] With reference to Figures 1 to 3 The clamping block 4 is slidably connected with an adjusting block 42 at the center thereof. The adjusting block 42 slides along the radial direction of the clamping block 4. A horizontal oil cylinder 44 is horizontally arranged on the clamping block 4, and the output shaft of the horizontal oil cylinder 44 is connected with the adjusting block 42 to drive the adjusting block 42 to slide. The adjusting block 42 is rotatably connected with a clamping ball 41 at the center thereof. The diameter of the clamping ball 41 is larger than the height of the adjusting block 42. The bottom of the clamping block 4 is open at the position corresponding to the clamping ball 41. The clamping ball 41 is provided with a clamping hole 411 which penetrates the center of the ball. The clamping hole 411 is also provided with a clamping mechanism. The end of the vibrating rod 3 passes through the fixed ball 51, the clamping ball 41, the clamping block 4, the clamping base 6 in sequence, and finally passes out of the avoiding hole.

[0050] With reference to Figures 1 to 3 The vibrating rod 3 penetrates the fixed ball 51 and the clamping ball 41. In the normal state, the fixed ball 51 and the clamping ball 41 do not rotate and are located on the same vertical line. The fixed hole 511 and the clamping hole 411 are located on the same straight line. At this time, the axis of the vibrating rod 3 coincides with the center line of the fixed base 5. When the fixed base 5 rotates, the vibrating rod 3 rotates synchronously. When the horizontal oil cylinder 44 drives the adjusting block 42 to slide, the adjusting block 42 drives the lower end of the vibrating rod 3 to move. Since the upper end of the vibrating rod 3 is fixed by the fixed ball 51, the vibrating rod 3 gradually inclines. During the movement of the vibrating rod 3, the fixed ball 51 and the clamping ball 41 gradually incline. The center axes of the fixed hole 511 and the clamping hole 411 intersect with the center line of the fixed base 5, that is, the center axis of the vibrating rod 3 intersects with the center line of the fixed base 5. At this time, when the fixed base 5 rotates, the vibrating rod 3 rotates around the center line of the fixed base 5. The end of the vibrating rod 3 in the concrete performs circular motion, and the vibrating range is larger.

[0051] With reference to Figures 1 to 3The clamping mechanism comprises a damping rod 72 and a clamping piece 71. A plurality of damping grooves 412 are circumferentially formed in the inner walls of the clamping hole 411 and the fixing hole 511, and each of the damping grooves 412 is provided with a damping piece 73. The damping rod 72 is fixed at one end with the damping piece 73 which is slidably connected in the damping groove 412, and is fixed at the other end with the clamping piece 71 which is arc-shaped. The outer wall of the vibrating rod 3 is provided with a clamping groove 31 which cooperates with the clamping piece 71, and the clamping piece 71 is embedded in the clamping groove 31 to clamp and fix the vibrating rod 3. The width of the clamping groove 31 is greater than the width of the clamping piece 71, so as to provide a moving space for the vibrating rod 3 when the clamping ball 41 moves horizontally.

[0052] With reference to Figures 1 to 3 The damping rod 72 is a telescopic rod, and the damping rod 72 is provided with a damping spring 75. The outer wall of the damping piece 73 is circumferentially fixed with a plurality of damping springs 74, and one end of the damping spring 74 away from the damping piece 73 is fixedly connected with the damping groove 412. When the vibrating rod 3 vibrates, the damping spring 75 buffers and dampens the horizontal vibration of the vibrating rod 3, and the damping spring 74 buffers and dampens the vertical vibration of the vibrating rod 3, and the two cooperate with each other to further improve the damping effect.

[0053] The implementation principle of the movable attached concrete vibrator is that the track 1 is started, the workbench 2 moves along the length direction of the track 1 to the working position, the bidirectional screw rod 21 rotates and the horizontal oil cylinder 44 is started to adjust the position of the vibrating rod 3, the hydraulic rod 12 controls the workbench 2 to descend, and the vibrating rod 3 is inserted into the concrete to vibrate the concrete.
