A bridge construction crane that generates electricity and can transport small objects

Abstract

The invention relates to a bridge construction crane using electricity for power generation and being capable of conveying small objects. The bridge construction crane includes a plurality of support arms, wherein a fixing bottom board is fixedly connected to the right lower end of each support arm. A metal shell is fixedly connected to the upper ends of the support arms, wherein an electricity engine is fixedly installed in the metal shell. Steel ropes are slidingly connected to the lower end of the metal shell, wherein a hook and a movable container are fixedly connected to the lower ends of the steel ropes. Observation platforms are fixedly installed on the left side of the upper surface of the metal shell. A supporting frame is fixedly connected to the center of the metal shell. A fixing steel rope is rotatably connected to the upper end of the supporting frame. Fixed guardrails are fixedly installed on two sides of the upper surface of the metal shell. Fixed connection plates are fixedly connected to the upper ends of the fixed guardrails. An operation room is fixedly installed on the upper end of the metal shell. The bridge construction crane increases turnover speed and transportation speed of transportation tools, ensures that goods are complete, and improves freight quality.

Description

technical field [0001] The invention relates to the field of road and bridge cranes, in particular to a bridge construction crane which adopts electric power generation and can transport small objects. Background technique [0002] The bridge crane is a lifting device that is placed horizontally over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall cement columns or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane is laid along the The rails on the elevated sides on both sides run longitudinally, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. However, the current bridge construction cranes have the following defects: 1. The bridge cranes used in the past are Diesel engine, diesel engine has high noise and vibration, high manufacturing cost, high requirements on fuel quality, and high weight. The fuel injection device o...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a bridge construction crane that adopts electric power generation and can transport small objects, which can solve the problems of the existing cranes that the diesel engine has high noise, large vibration, high manufacturing cost, and emission pollution. The electric motor of the present invention Zero emission, no exhaust gas discharge during use, no pollution to the environment, the energy utilization rate of the electric motor is high, because a single electric energy is used, the engine, transmission, fuel tank, cooling and exhaust system are omitted, so the structure is relatively simple, The noise is small, and the crane can be charged during the low peak of electricity consumption, which can stabilize the peak-valley difference of the power grid and make full use of the power generation equipment. The lower end of the bridge crane is equipped with a mobile container. The mobile container is replaced by mechanical loading and unloading, which can save labor. , can reduce loading and unloading operations, shorten loading and unloading time, improve transportation efficiency, and speed up the turnover speed and delivery speed of transportation tools, ensure that the goods are in good condition, improve the quality of freight transportation, reduce cargo damage and poor cargo, and can transport some small items
