Lifting platform of construction vehicle

Abstract

The invention provides a lifting platform of a construction vehicle, which comprises a lifting platform and a platform lifting device, and is characterized in that: the lifting platform has two stages of expansion plates, namely first-stage expansion plates and second-stage expansion plates; the first-stage expansion plates are positioned on two sides of the lifting platform and are hinged on the lifting platform, and overturning oil cylinders are arranged below the first-stage expansion plates and the lifting platform; the second-stage expansion plates are expansion plates with a draw type structure and are arranged in the first-stage expansion plates, namely the second-stage expansion plates are inserted into the first-stage expansion plates; and expansion cylinders are arranged between the first expansion plates and the second expansion plates. The lifting platform has the advantages of increasing the operation, activity and working space of construction operators, improving working safety conditions and environments, allowing constructors to work alternately at a high altitude, effectively reducing auxiliary work load, auxiliary work time and auxiliary workers and improving operation safety and production efficiency and is applicable to various construction vehicles for coal mine continuous mining, continuous excavation and comprehensive digging.

Description

technical field The invention relates to coal mine underground excavation equipment, which is suitable for large, medium and small coal mines, and is a lifting platform for the construction vehicle of the roof bolt and anchor cable construction machinery required for continuous mining, continuous excavation, and fully mechanized excavation construction of various roadways. Background technique At present, the main methods of roadway excavation in various coal mines are continuous mining, continuous excavation, and fully mechanized excavation. Body drilling rig or crawler-type liftable roof bolt and anchor cable construction drilling rig, such as the disclosed crawler-type liftable roof bolt and anchor cable construction drilling rig in Chinese Patent No. 200720102731. Type traveling mechanism, advance support; the traveling mechanism is driven by a hydraulic motor, and the drilling rig platform is installed on the frame of the traveling mechanism; A hydraulic cylinder-type ...

AI Technical Summary

Problems solved by technology

Most of the drilling rig platforms of the existing construction vehicles are fixed platforms on the crawler-type traveling mechanism, or movable small platforms that can be raised and lowered with the hydraulic drilling rig. For the construction drilling rig mentioned above, the operation and activity work space of the construction operators is small, the working safety conditions and environment are poor, and the safety factor is low. Due to the large number of drilling holes and the large number of construction personnel, the construction personnel cannot work alternately at high altitudes, resulting in operational efficiency. Low
