Abstract
The utility model discloses an energy-saving double-girder crane, which has high strength and rigidity and low energy consumption. Two trolley lifting devices are parallelly arranged on a trolley track on a crane bridge main girder, a trolley traveling mechanism is arranged on a trolley rack, and a cart driving device is arranged on each end socket of the end girder of a bridge frame. The traveling crane adopts a four-girder structure comprising two box-shaped main girders and two end girders, which are connected through 8.8-grade bolts, and the original QD standard trolley with A7-grade trolley with hoist trolley is replaced. The crane is made of QPTIM 900/960/1100 QC high-strength steel plates.
Description
One, technical field
The utility model relates to a kind of energy-conservation double girder crane.
Two, background technology
At present, there is big inadequately, the not energy-conservation shortcoming of intensity, rigidity in double girder crane.
Three, summary of the invention
The purpose of this utility model is exactly that a kind of energy-conservation double girder crane that overcomes above shortcoming will be provided; Advantage: convenient transportation and installation; The import cucurbit can reach A7 rank cucurbit dolly and replace former QD standard dolly, and dolly weight alleviates greatly, under same intensity, rigidity condition, and crane structure weight saving, the complete machine power reduction reaches energy-conservation and the effect of saving material; Hoist and the operating unit reductor need not oiling, no leak, noise little, be beneficial to environmental protection; The hoisting crane height is low, and wheel load is little, can reduce the workshop cost.
A kind of energy-conservation double girder crane is characterized in that: parallel installation two cover dolly jack up units on the trolley track on the crane bridge girder, wheeling mechanism is installed on trolley frame, and a cover cart actuating device all is housed on four terminations of end carriage of crane span structure; Driving connects into four girder constructions by two box girders and two butt beams by 8.8 grade bolts, replaces former QD standard dolly with A7 rank cucurbit dolly; The hoisting crane material is the OPTIM900/960/1100QC high tensile steel plate.
Four, description of drawings
Fig. 1 is a kind of structure principle chart of energy-conservation double girder crane.
Five, the specific embodiment
Specifically introduce below in conjunction with accompanying drawing, in Fig. 1: 1 is end carriage; 2 is the box girder; 3 is the cucurbit dolly.A kind of energy-conservation double girder crane is characterized in that: parallel installation two cover dolly jack up units on the trolley track on the crane bridge girder, wheeling mechanism is installed on trolley frame, and a cover cart actuating device all is housed on four terminations of end carriage of crane span structure; Driving connects into four girder constructions by two box girders and two butt beams by 8.8 grade bolts, replaces former QD standard dolly with A7 rank cucurbit dolly; The hoisting crane material is the OPTIM900/960/1100QC high tensile steel plate.
