Description

Jacking device for multifunctional sand sleeper slope compensation construction Technical Field The utility model relates to the technical field of jacking devices, in particular to a jacking device for multifunctional sand sleeper slope compensation construction. Background With the increasing importance of the national environmental protection, the new technology of the dam construction by filling the sand pillow underwater and filling the stone blocks on the sand pillow gradually replaces the traditional stone throwing masonry method, the new technology accelerates the construction progress and saves the investment, and in the course of course improvement, the sand pillow needs to be delivered into the water by using a lifting device on a ship. The existing jacking platform of the jacking device is in a fully-opened mode, once workers mistakenly enter the jacking platform during jacking operation, the workers are very easy to fall down and slide down to the sea due to unstable gravity centers, and life safety is influenced. For this reason, we propose a multi-functional sand pillow mends slope construction's jacking device and solve above-mentioned drawback. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provides a jacking device for multifunctional sand sleeper slope compensation construction. The lifting device for the multifunctional sand pillow slope compensation construction comprises a lifting platform, wherein an electric cylinder is fixed on the lower surface of the lifting platform through a hinge piece, fixing columns are arranged on one side of the electric cylinder, a mounting seat is fixed on the upper surface of the lifting platform, a plurality of mounting seats are arranged, a light projector is fixed on the upper surface of one mounting seat, a light receiver matched with the light projector is arranged on the upper surface of the other mounting seat, a broadcasting device is arranged on the upper surfaces of the light projector and the light receiver, a buzzer is arranged on the side surfaces of the light projector and the light receiver, a controller is arranged on the side surface of the lifting platform, and a wireless transmission module is arranged inside the controller. Preferably, an angle sensor is arranged on the side surface of the jacking platform, a weighing sensor is welded on the lower surface of the electric cylinder and the lower surface of the fixing column, and the angle sensor and the weighing sensor are connected with a controller through wires. Preferably, the upper surface of the jacking platform is a smooth surface. Preferably, the lower surface of the weighing sensor is welded with a fixed lifting lug.
