Problems solved by technology

[0003] The shortcomings of this loading and unloading system are: (1) When the wheel-rail adhesion coefficient is very low, it is easy to cause the wheels of the electric trolley to lock up and slip, and the brakes are out of control, so that the positioning accuracy cannot meet the requirements; (2) Interference factors such as strong wind It will cause the container to sway excessively; (3) Influencing factors such as the stability of the network control system, the control accuracy of frequency conversion speed regulation, the working efficiency of the brake mechanism, and the setting of control parameters will also cause positioning errors
Once these situations occur, it will bring difficulties in box alignment and drop-off. At present, the existing fixed wedge design for guiding drop-off boxes cannot meet the requirements of all-weather automated docks

Embodiment Construction

[0026] Further illustrate the present invention below in conjunction with accompanying drawing.

[0027] Press the following parts to Figure 1-Figure 5 Those skilled in the art can successfully implement the connection in the manner shown.

[0028] The extended bottom plate 3 adopts 45×45×5mm angle steel welded into a square frame of 800×400mm, and the upper surface is covered with 800×400×10mm steel plate as the plane of the extended bottom plate. 200×75×9mm channel steel is welded into two triangular support frames 11 with a side length of 300×400×500, which are supported under the plane of the extended bottom plate 3. When in use, the bottom of the extended bottom plate 3 can be connected to the electric trolley 1 through the triangular support frame 11 , and the expansion base plate 3 is fixed around the electric trolley 1 by bolts 12,

Abstract

A container locating apparatus for unloading a container on automatized dock is composed of extended base plate, electric push rod, wedge block with rubber pad, drive connection rod consisting of long and short rods, and the washer-type force sensor arranged in said rubber pad.

Description

technical field [0001] The invention belongs to the technical field of electromechanical integration, and in particular relates to a container drop-off positioning device which can be used in an automatic container wharf. Background technique [0002] Relevant scientific research projects: R&D and application of core technologies for efficient and intelligent three-dimensional loading and unloading container terminals (Shanghai Science and Technology Commission major project 06DZ11202). Cooperating with Shanghai Zhenhua Port Machinery Group Co., Ltd. to develop an economical and efficient automated container terminal and yard system, one of the difficulties encountered is the high-precision positioning problem caused by the high-speed operation of the trolley. Since the automated terminal needs to achieve high efficiency, all-weather, and unmanned operation, any failure in any link will affect the entire system. In order to meet the requirements of high-speed operation and ...
