To solve this problem, we can design a detachable and convenient transportation device, which can conveniently, accurately and quickly carry out the vertical lifting and horizontal movement of the cable cover. The vertical lifting height and width can be adjusted to adapt to different specifications of cables. Cover plate.
Separate manual hydraulic jacks are widely used in lifting, supporting, jacking, pushing, pulling, squeezing and other forms of operations, not only can reduce the work intensity of construction workers, but also facilitate transportation and carrying. A separate manual hydraulic jack is used as the mechanical power part of the device to separate the working pump from the jack. The jack has simple structure, light weight, convenient loading and unloading, low operating force and high speed. According to actual application requirements, considering that the instantaneous stress during the lifting process exceeds the actual weight of the cover plate, the lifting tonnage is designed to be 5t.
The device has a total weight of 40 kg and is divided into four parts. The lifting rod with an area of 0.5 square meters is divided into three sections, each with a length of 0.9 meters and a total length of 2.7 meters. The horizontal rod is made of epoxy glass fiber reinforced plastic round pipe, the pipe diameter is 80mm, and the wall thickness is 3mm. The connection part of the horizontal rod is reinforced by male and female coupling nuts. The number of horizontal rod cross-sections is selected according to actual construction needs to meet the hoisting, transportation and storage requirements of different width cable covers.
