Description

[0001] The invention relates to the technical field of shock absorption of municipal engineering equipment, in particular to a shock absorption device for municipal construction engineering equipment. Background Art

[0002] Municipal engineering construction is a complex system engineering, which requires the cooperation of professional technicians from all aspects and a large number of engineering equipment. In the process of municipal construction, a large number of engineering equipment will often vibrate during their own operation or collision with other objects. Continuous vibration can easily cause the loosening and aggravated wear of equipment parts, affecting the service life of the equipment. At this time, it is necessary to install a shock absorbing device to reduce the shock. However, the shock absorbing devices currently used have some shortcomings, as follows:

[0003] The shock absorbing devices currently used are generally composed of springs or dampers. Dampers are installed on engineering equipment to reduce shock. However, the shock absorption effect is poor if only springs and dampers are used for shock absorption, and the kinetic energy absorption effect is not good. The engineering equipment still needs to vibrate at a certain frequency before the vibration can be eliminated.

[0010] Preferably, a sliding connector is fixedly mounted on the bottom end of the connecting column, a resistor is fixedly mounted on the inner wall of the supporting seat, and the sliding connector is slidingly electrically connected to the resistor in the inner cavity of the supporting seat.

[0011] Preferably, the cross-sections of the upper portion of the support seat and the connecting column are square.

[0012] The present invention has the following beneficial effects:

[0013] 1. By setting up nine groups of receiving plates and limit devices, the arrangement of each receiving plate can be changed to adapt to different equipment, and can provide good support for the corners of the equipment to prevent the equipment from tipping over during use. The shock-absorbing spring is one of the shock-absorbing methods. When the shock-absorbing spring cannot meet the shock-absorbing requirements, the support seat and the connecting column are energized by the power supply, and then the current is transmitted to the electrorheological fluid in the vertical rubber sleeve and the connecting rubber sleeve. Under the action of the current, the viscosity of the electrorheological fluid increases. On the one hand, the shock absorption of the engineering equipment is achieved by the energized electrorheological fluid, and the vibration kinetic energy of the engineering equipment is absorbed, thereby enhancing the shock absorption effect of the device. On the other hand, the blocking property of the shock-absorbing spring is achieved by the electrorheological fluid, and the deformation degree of the shock-absorbing spring is reduced, thereby enhancing its shock absorption effect.

[0014] 2. By setting the connecting tube and the fixed support box, the connecting rubber sleeve is connected to the connecting tube, and under the connection of the electrorheological fluid, the shock absorption and energy absorption effect of the electrorheological fluid in the vertical direction is enhanced, and its support effect is strengthened to improve the overall stability of the device. In addition, by setting the solenoid valve and the square connecting rubber tube, support is formed on the side of the connecting rubber sleeve, and the kinetic energy of the lateral vibration of the engineering equipment is absorbed, further eliminating the vibration of the engineering equipment, and as the current increases, the electrorheological fluid gradually shows the characteristics of a solid, and then forms a support on the side of the connecting rubber sleeve, further improving the overall structural property of the device and enhancing the stability of the equipment.

[0015] 3. By setting the sliding connector, when the engineering equipment vibrates, the connecting column is driven up and down by the receiving plate, and the connecting column drives the sliding connector to move up and down inside the support seat, thereby changing the current in the circuit, thereby changing the viscosity of the electrorheological fluid. However, when the vibration is too large, the current becomes larger, increasing the viscosity of the electrorheological fluid, quickly eliminating the vibration of the engineering equipment, maintaining the stability of the engineering equipment, and according to the characteristics of the electrorheological fluid, reducing the vibration and collision of the shock absorbing device, thereby increasing the service life of the equipment.
