Integral hydraulic elevating road pile

Abstract

The invention relates to the technical field of elevating road piles and in particular relates to an integral hydraulic elevating road pile. The integral hydraulic elevating road pile comprises an external cylinder fixed underground. Over the external cylinder is provided a ground panel aligned to the construction ground; an internal cylinder accommodating an elevating road pile elevating cylinder is disposed in the external cylinder; the lower end of the elevating cylinder is connected with the upper end of a piston rod of a hydraulic cylinder; the lower end of the hydraulic cylinder is installed on a pedestal hydraulic pipeline module; the pedestal hydraulic pipeline module is further provided with a gear pump mechanism; the upper part of the gear pump mechanism is connected with a power output shaft of a motor via a coupler; the lower part of the gear pump mechanism is communicated with a hydraulic oil pipeline formed in the pedestal hydraulic pipeline module; a balance retaining vale is disposed in the hydraulic oil pipeline; one end of the hydraulic oil pipeline is communicated with a hydraulic cylinder communicated with one end of the gear pump mechanism. The integral hydraulic elevating road pile employs a modularized structure, thereby possessing convenient assembling and construction; and the hydraulic elevating road pile is integrally designed, thereby possessing great sealing property and prolonged service life.

Description

technical field [0001] The invention relates to the technical field of lifting road piles, in particular to an integrated hydraulic lifting road pile. Background technique [0002] Under the existing technology, hydraulic lifting road piles are more and more widely used in parking lots, schools, government offices, and even parking spaces along the road. There are hydraulic road piles. The hydraulic lifting road piles are easy to control and beautiful in appearance. While acting as a barrier, it can also ensure the order and full utilization of the operating site. [0003] The structure of the current hydraulic lifting road pile is generally to drive the hydraulic pump to control the hydraulic cylinder through the motor, so that the piston rod of the hydraulic cylinder is stretched out and retracted, thereby driving the lifting cylinder up and down to realize the lifting and landing of the road pile, but the current Hydraulic lifting bollards have the following disadvantage...

AI Technical Summary

Problems solved by technology

[0004] 1. The product structure is complex, the assembly process between parts is cumbersome, and the construction is very inconvenient

[0005] 2. The lifting cylinder, hydraulic cylinder, motor, and hydraulic pump are located in different housings, and the overall structure is poor, which is not convenient for transportation and installation

[0006] 3. The product has poor sealing performance and is prone to water seepage, resulting in reduced service life of the product

[0007] 4. The power supply needs to be external, and the use in remote areas is limited
