Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete forming vibration, in particular to an efficient and energy-saving concrete forming vibration device. BACKGROUND

[0002] Concrete forming vibration is a key process for making concrete mixture compact by mechanical vibration. The core is to overcome the internal friction and cohesion of concrete by using vibration energy. The friction between concrete particles is reduced by vibration wave, and the particles are in a liquefied flow state. The particles are rearranged under the action of gravity, filling the voids to reduce the internal voids of concrete and improve the strength, durability and surface flatness of concrete.

[0003] For example, the improved concrete vibrating device for building construction disclosed in CN112160604B adds a mechanical vibrating device to replace the traditional manual concrete vibrating device. This ensures the consistency of the vibrating position during vibration. However, the transmission mode of the gear driving the vibrating rod up and down only allows the vibrating rod to vibrate the concrete once per revolution of the motor, resulting in a low vibration frequency. Moreover, the directions of the external forces applied by multiple vibrating rods to the concrete are different, and there is a possibility of mutual cancellation of the vibrating forces. SUMMARY

[0004] To solve the problems in the prior art, the present application provides an efficient and energy-saving concrete forming vibration device.

[0005] The technical scheme adopted by the present application to solve the technical problems is: an efficient and energy-saving concrete forming vibration device, comprising a circular box, a plurality of vibrating assemblies for vibrating concrete are arranged on the outer wall of the circular box, a driving assembly for providing power is arranged at the upper end of the circular box, and a linkage assembly connecting the vibrating assemblies is arranged on the lower surface of the circular box.

[0006] The vibrating assembly comprises a fixed box fixedly connected to the outer wall of the circular box, a fixed block fixedly connected to the inner wall of the fixed box, a plug hole formed in the interior of the fixed block, a plug rod inserted into the plug hole, a fixed ring fixedly sleeved on the surface of the plug rod, a spring clamped in the interior of the fixed box and sleeved on the surface of the plug rod, a clamping groove formed in the lower surface of the plug rod, a plurality of semicircular strips fixedly connected in the interior of the clamping groove, a swing hole formed in the bottom of the fixed box, a semicircular block clamped at the upper end of the swing hole, a vibrating rod fixedly sleeved in the interior of the semicircular block, and a plurality of grooves formed in the upper surface of the vibrating rod.

[0007] Specifically, the upper end of the vibrating rod is inserted into the clamping groove, and the grooves are matched with the semicircular strips.

[0008] Specific, the end surface of the insertion rod near the round box is provided with an arc surface.

[0009] Specific, the driving assembly includes a clamping plate, the clamping plate is clamped on the inner wall of the upper end of the round box, the upper surface of the clamping plate is fixedly connected with a motor, the output end of the motor is fixedly connected with a cam, the side wall of the cam is provided with a notch, and the outer wall of the round box is provided with an opening.

[0010] Specific, the opening corresponds to the fixed box, and the opening and the outer circular side wall of the clamping plate are clamped with each other.

[0011] Specific, the linkage assembly includes four support plates, the support plates are fixedly connected to the outer wall of the round box, the two sides of the support plates are fixedly connected to the outer wall of the fixed box, the bottom center of the round box is fixedly connected with a rotating seat, the rotating seat is clamped with a rotating block inside, the lower end of the rotating block is fixedly connected with a cylinder, and the lower end of the outer wall of the cylinder is fixedly connected with four steel wires.

[0012] Specific, one end of the four steel wires is fixedly connected to the surface of the vibrating rod, and the four steel wires are of the same length.

[0013] The beneficial effects of the application are as follows:

[0014] (1) The high-efficiency energy-saving concrete forming vibration device improves the vibration frequency through the linkage design of the driving assembly and the vibrating assembly. The continuous rotation of the cam in the driving assembly can push the insertion rod multiple times through the arc surface, and the spring is reset quickly, so that the vibrating rod can complete more vibration actions in unit time, effectively solving the problem of low vibration frequency of the traditional gear transmission device, and greatly improving the concrete compaction efficiency.

[0015] (2) The high-efficiency energy-saving concrete forming vibration device realizes efficient energy utilization and vibration force concentration through the synergistic effect of the vibrating assembly and the linkage assembly. The groove at the upper end of the vibrating rod matches the semicircular strip in the insertion rod slot, and the elastic potential energy of the spring is reset, reducing the energy loss in the power transmission process. The steel wires of the linkage assembly cooperate with the rotating seat, so that multiple vibrating rods maintain the consistency of the stress direction during movement, avoiding the phenomenon that the vibration forces in the traditional device offset each other, improving the energy utilization rate and achieving the energy-saving effect.

[0016] (3) The high-efficiency energy-saving concrete forming vibration device, through the swing design of the vibrating rod and the cooperation of multiple components, improves the uniformity and coverage of vibration. The vibrating rod rotates in the swing hole through the semicircular block, and in combination with the linear motion of the inserting rod and the elastic deformation of the spring, can produce a certain angle of swing in the vibration process, expand the vibration range, and at the same time, multiple vibration components are distributed along the circumference of the circular box, cooperate with the synchronous action of the linkage assembly, can cover the concrete area in all directions, effectively eliminate the vibration blind area of the mold corners or steel dense area.

[0017] (4) The high-efficiency energy-saving concrete forming vibration device has stable structure and strong adaptability. The supporting plate rigidly connects the fixed box and the circular box, enhances the overall structural strength of the device, can adapt to high-strength vibration operation, and the detachable cooperation of the vibrating rod and the inserting rod facilitates the replacement of vibrating rods with different lengths or diameters according to the construction requirements, and improves the adaptability of the device to different concrete components.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application will be further described below in conjunction with specific embodiments.

[0028] Please refer to Figures 1 to 7 The present application provides the following technical solutions:

[0029] Embodiment one: an efficient and energy-saving concrete forming vibration device, comprising a round box 1, a plurality of vibration assemblies 2 for vibrating concrete are arranged on the outer wall of the round box 1, a driving assembly 3 for providing power is arranged at the upper end of the round box 1, and a linkage assembly 4 connected with the vibration assemblies 2 is arranged on the lower surface of the round box 1.

[0030] The vibration assembly 2 comprises a fixed box 21 fixedly connected to the outer wall of the round box 1, a fixed block 22 fixedly connected to the inner wall of the fixed box 21, an insertion hole 23 formed in the interior of the fixed block 22, an insertion rod 24 inserted into the insertion hole 23, a fixed ring 25 fixedly sleeved on the surface of the insertion rod 24, a spring 26 clamped in the fixed box 21 and sleeved on the surface of the insertion rod 24, a clamping groove 27 formed in the lower surface of the insertion rod 24, a plurality of semicircular strips 28 fixedly connected to the interior of the clamping groove 27, a swing hole 29 formed in the bottom of the fixed box 21, a semicircular block 210 clamped at the upper end of the swing hole 29, a vibration rod 211 fixedly sleeved in the interior of the semicircular block 210, and a plurality of grooves 212 formed in the upper surface of the vibration rod 211.

[0031] The upper end of the vibration rod 211 is inserted into the clamping groove 27, the grooves 212 are matched with the semicircular strips 28, the semicircular strips 28 are embedded in the grooves 212, and the vibration rod 211 is caused to shake up and down by the semicircular strips 28 extruding the grooves 212.

[0032] An arc surface 213 is formed on the surface of one end of the insertion rod 24 close to the round box 1, the length of the arc surface 213 is designed to match the arc length of the protruding part of the cam 33, the protruding part of the cam 33 can be contacted with the arc surface 213 twice every rotation, the two sides of the protruding part are respectively contacted, the spring 26 is quickly reset, the vibration frequency of the vibration rod 211 reaches twice the rotation speed of the motor, and the work efficiency is significantly improved.

[0033] In use, first, the upper end of the vibrating rod 211 is inserted into the clamping groove 27 of the insertion rod 24, and the groove 212 on the surface of the vibrating rod 211 is completely matched with the semicircular strip 28 in the clamping groove 27. When the insertion rod 24 moves under the push of the cam 33, the semicircular strip 28 is embedded in the groove 212, and the vibrating rod 211 is brought up and down by the extrusion of the semicircular strip 28 in the groove 212, ensuring that the linear motion of the insertion rod 24 is efficiently converted into the movement of the vibrating rod 211. At the same time, since the vibrating rod 211 is clamped in the swing hole 29 of the fixed box 21 by the semicircular block 210, when the insertion rod 24 moves with the vibrating rod 211, the semicircular block 210 can rotate slightly in the swing hole 29, so that the vibrating rod 211 produces a swing angle of ±5°. The swing is achieved through the gap between the groove 212 and the semicircular strip 28, which does not affect the transmission of the longitudinal vibrating force and can expand the vibrating range and improve the fluidity of the concrete particles.

[0034] In the technical scheme of the embodiment, the driving assembly 3 comprises a clamping plate 31 clamped on the inner wall of the upper end of the circular box 1, a motor 32 fixedly connected to the center of the upper surface of the clamping plate 31, a cam 33 fixedly connected to the output end of the motor 32, and an opening 35 formed in the outer wall of the circular box 1.

[0035] The opening 35 corresponds to the fixed box 21, and the opening 35 and the outer circular sidewall of the clamping plate 31 are clamped with each other, so that the insertion rod 24 in the fixed box 21 can contact the cam 33 in the circular box 1 through the opening 35.

[0036] In use, the device is placed above the concrete mold to be vibrated, and the motor 32 in the driving assembly 3 is started. The output end of the motor 32 drives the cam 33 to rotate around the axis. When the protruding part of the cam 33 rotates to contact the arc surface 213 of the insertion rod 24, the cam 33 exerts an outward pushing force on the arc surface 213, pushing the insertion rod 24 to move away from the circular box 1 along the insertion hole 23 of the fixed block 22. The output end of the motor 32 is rigidly connected to the cam 33, and the angle of the notch 34 of the cam 33 is 60°-90°. When the notch 34 rotates to the position opposite to the insertion rod 24, the cam 33 is disengaged from the insertion rod 24. At this time, the spring 26 drives the insertion rod 24 to reset, completing a vibration cycle.

[0037] In the technical scheme of the embodiment, the linkage assembly 4 comprises four support plates 41 fixedly connected to the outer wall of the circular box 1, the outer wall of the fixed box 21, a rotating seat 42 fixedly connected to the bottom center of the circular box 1, a rotating block 43 clamped in the rotating seat 42, a cylinder 44 fixedly connected to the lower end of the rotating block 43, and four steel cables 45 fixedly connected to the lower end outer wall of the cylinder 44.

[0038] One end of the four steel ropes 45 is fixedly connected to the surface of the vibrating rod 211, and the four steel ropes 45 have the same length and pull the vibrating rod 211 to swing synchronously.

[0039] In use, the four support plates 41 in the linkage assembly 4 are connected to the adjacent fixed boxes 21 and the round box 1 respectively, forming a triangular stable structure, which enhances the anti-deformation ability of the fixed boxes 21 during the vibrating process. The rotating seat 42 at the bottom of the round box 1 is gap-fitted with the rotating block 43 with a gap of 0.5-1mm, ensuring that the rotating block 43 can rotate flexibly. The cylinder 44 at the lower end of the rotating block 43 is connected to the four steel ropes 45, and the other ends of the steel ropes 45 are fixed to the middle positions of the four vibrating rods 211, and the lengths of the steel ropes 45 are the same with an error of ≤1mm. When a vibrating rod 211 moves downward, it pulls the cylinder 44 to tilt in this direction through the steel rope 45, and the cylinder 44 drives the rotating block 43 to rotate in the rotating seat 42, thereby pulling the remaining vibrating rods 211 to move downward synchronously through the other steel ropes 45. Similarly, when the vibrating rod 211 moves upward, the pulling force of the steel rope 45 disappears, and the vibrating rod 211 moves upward synchronously under the action of the spring 26. This structure ensures that the displacement amount and movement direction of the four vibrating rods 211 are consistent, avoids force cancellation, and improves the utilization rate of vibrating energy.

[0040] The above shows and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
