Description

Technical Field

[0001] The invention relates to a vibrating device for cement concrete pavement construction, belonging to the technical field of engineering machinery. Background Art

[0002] The vibrating rod is one of the indispensable equipment to ensure the quality of the project during the pouring of cement concrete pavement. The working principle of the vibrating rod is that it is equipped with an eccentric vibration system inside, which rotates at high speed under the drive of an electric motor or compressed air, generating unbalanced centrifugal force, driving the rod head to make high-frequency and low-amplitude circular vibrations. At present, when pouring a road surface of a certain width, since the vibration frequency and amplitude of a vibrating rod are limited, the construction unit generally fixes multiple vibrating rods side by side on a rack with the same width as the poured road surface, and compacts the entire road surface at the same time to improve the density of cement concrete in the entire road surface width and improve work efficiency. However, the price of the vibrating rod is relatively high, and the construction cost is very high if multiple vibrating rods are purchased at a time. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a vibrating frame with a simple structure and capable of reducing the construction cost of cement concrete pavement.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] The vibrating frame includes a slurry lifting pipe, on which a vibrating rod driven by a motor is radially penetrated, and a vibrating pipe parallel to the vibrating rod is fixedly arranged on the slurry lifting pipe, the end of the vibrating pipe is fixedly connected to a vibration transmission rod, a connecting sleeve is fixedly arranged on the vibration transmission rod at a position corresponding to the vibrating rod, a connecting nut is fixedly arranged on the end of the vibrating rod, and the connecting sleeve is connected to the connecting nut through a connecting bolt.

[0006] A further improvement of the present invention is that a fixed block with a circular arc surface is fixedly arranged in the slurry lifting pipe hole, a clamping plate with a circular arc surface is arranged above the fixed block, a vibrating rod is clamped between the circular arc surface of the fixed block and the clamping plate, and a clamping bolt that passes through the clamping plate and can clamp the vibrating rod is screwed on the fixed block.

[0007] A further improvement of the present invention is that connecting pins are fixedly arranged in the slurry lifting pipe holes on both sides of the vibrating rod, the connecting pins are penetrated in the holes of the hinged plate, and the holes of the hinged plate are clearance-matched with the connecting pins.

[0008] A further improvement of the present invention is that a downwardly bent limiting guide hook is fixedly provided on the end of the vibrating pipe.

[0009] A further improvement of the present invention is that a hinged connecting plate is fixedly arranged above the hinged plate, and a vibration-damping suspension spring is fixedly arranged on the hinged connecting plate.

[0010] A further improvement of the present invention is that a slurry retaining plate for preventing slurry from entering the vibrating rod and the slurry lifting pipe is hung on one side of the hinged plate.

[0011] A further improvement of the present invention is that baffles are respectively arranged in the slurry lifting pipe holes on both sides of the fixing block to prevent mud from entering the slurry lifting pipe cavity.

[0012] A further improvement of the present invention is that an anti-loosening gasket is arranged on the clamping bolt.

[0013] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is:

[0014] The present invention transmits the high-frequency and low-amplitude vibration of a vibrating rod to a vibrating pipe on the side through a slurry lifting pipe and a vibration transmission rod connected thereto, so that the vibrating pipe and the vibrating rod vibrate at the same frequency, thereby expanding the vibration range of a single vibrating rod; by providing the vibrating pipe, the vibration density is increased; in addition, by replacing adjacent vibrating rods with vibrating pipes, the number of vibrating rods purchased can be reduced, thereby reducing construction costs.

[0015] A fixing block and a pressing plate are fixedly arranged in the slurry lifting pipe hole to clamp the vibrating rod in the vibrating pipe between the fixing block and the pressing plate, so that the vibrating rod can be easily replaced when it is damaged.

[0016] The vibrating rod is fixed on the slurry lifting pipe, and a vibrating pipe is also provided on the slurry lifting pipe. The vibrating rod and the vibrating pipe are also connected by a vibration transmission rod, so that the high-frequency vibration of the vibrating rod can be transmitted to the vibrating pipe, which vibrates the cement concrete pavement synchronously with the vibrating rod to increase the density of the pavement.

[0017] When the slurry lifting pipe vibrates synchronously with the vibrating rod, it keeps hitting the road surface, causing the mud to float out of the road surface, playing the role of lifting the slurry and helping to improve the smoothness of the road surface.

[0018] Connecting pins are arranged on both sides of the vibrating rod, so that the hinged plate and the slurry lifting pipe can rotate relative to each other. When the hinged plate pulls the slurry lifting pipe upward, the vibrating rod is rotated to a vertical state and recovered, which can save space and facilitate the relocation of the project.

[0019] A downward-bent limit guide hook is also provided at the end of the vibrating pipe. At the beginning of the project, when the slurry lifting pipe moves downward, the limit guide hook can touch the ground first, guiding the vibrating pipe and the vibrating rod to tilt. Moreover, the vibrating rod will maintain a certain distance from the ground during work, which can not only ensure that the vibrating rod is not damaged, but also ensure that the cement concrete in the lower layer of the road surface is vibrated and compacted.

[0020] A vibration-damping suspension spring is arranged on the articulated connection plate, and the slurry lifting pipe is connected to other devices through the vibration-damping suspension spring to cooperate with other devices, and can also reduce the influence of the vibration of the vibrating rod on other devices.

[0021] A slurry baffle is mounted on one side of the hinged plate to prevent mud from entering the vibrating rod and causing damage to the vibrating rod. It can also prevent mud from entering the slurry lifting pipe, increasing the weight of the slurry lifting pipe and weakening the vibration of the vibrating pipe.

[0022] The baffle inside the slurry lifting pipe hole also prevents mud from entering the slurry lifting pipe, increases the weight of the slurry lifting pipe, and weakens the vibration of the vibrating pipe.

[0023] An anti-loosening gasket is arranged on the clamping bolt to prevent the clamping bolt from loosening or falling off, thereby causing the vibrating rod to loosen and weakening the vibration effect of the vibrating tube. BRIEF DESCRIPTION OF THE DRAWINGS
