Abstract
The utility model relates to a light tyre type portal crane, which adopts four groups of cylindrical reel drums having bound steel cables to finish the lifting and operating of the cargo; the lifting space protection of the cargo can be realized by the mode of traction of a pulley and a steel wire that are supported on the pulley spindle; the anti-overthrow protecting of the crane is realized by adopting a mounting fork protecting and supporting mode when the tyre is leaked gas. The utility model can be used in a container yard for finishing the loading and pile working of the shipping container, and can also be used for loading and unloading operation to the long and big goods in the large sized enterprise. The utility model has simple structure, convenient operation and flexible motion.
Description
Affiliated technical field
The utility model relates to a kind of rubber tired gantry crane tool equipment, especially can be at the light tyre formula transfer crane equipment of stockyard handling freight container.
Background technology
Along with the development of Chinese national economy and with the increase of international association, China's freight container traffic amount development is very fast.Since 1998, China's harbour container loading and unloading capacity increases more than 30% every year on average, and the development of freight container traffic has promoted the development of container handling transportation device.At present, the known rubber tired crane tool equipment of finishing container handling, carrying in the stockyard has tyred container door type crane, container face crane, container fork lift, container straddle carrier etc.The rubber tired crane tool has the motor-driven flexible characteristic of operation.Tyred container door type crane is mainly used in container handling, the stacking operation in stockyard, and container face crane, container fork lift are mainly used in the carrying and the pile of freight container, and container straddle carrier has been taken into account the lifting and the carrying of freight container.But above-mentioned rubber tired crane tool equipment price is very high, surplus in the of 300 ten thousand yuan at least, and surplus in the of 600 ten thousand yuan at most.And the common stockyard of annual handling capacity more than 1000TEU just needs to be equipped with the container facility more than 2, causes customer investment huge, the operating cost height.
The purpose of this utility model is to provide that a nested structure is simple, cost is low, easy to operate, a kind of light tyre formula transfer crane that has rubber tired crane maneuverability characteristics simultaneously.
Summary of the invention
The utility model provides a kind of light tyre formula transfer crane (being called for short four winding drum field bridge), adopted the lightness design on this light tyre formula transfer crane structure, cost only is 1/3～1/4 of other rubber tired crane tool equipment, and has the motor-driven flexible characteristic of rubber tired crane tool operation.
The scheme that its technical matters that solves the utility model adopts is: on general design, adopt 4 groups of reel lay winding wire ropes, rely on the forward and backward folding and unfolding steel rope of reel to realize hoisting and moving of goods, reel and relative drive systems are not placed on the running trolley, and be placed on the door frame underbeam, the running trolley quality of lifting object is reduced greatly; Adopt steel wire traction to touch the travel switch mode and realize the goods position limitation protection that hoists; The anti-protection of toppling of hoisting crane behind the employing fork protection support realization tire flat.
Effect of the present utility model is that when keeping the motor-driven flexible characteristic of rubber tired crane tool operation, application lightness designing technique reduces equipment manufacturing cost significantly, saves construction investment.
Use the light tyre formula transfer crane (four winding drum field bridge) that the utility model provides, can be used for loading and unloading and pile work that container depot is finished freight container, also can be used for large enterprise, part carries out loading and unloading operation to growing up.

The specific embodiment
Among Fig. 1, door frame (3) is installed on the tire support system (8), and cart operation actuating device (1) tire on the drive wheels support system is finished the cart operation; Running trolley (5) uses steel rope to hang container spreader (4), and rely on hoist-trolley travelling system driving device (2) drives steel cable winding system (7), finish freight container hoist and along the operation on the trolley travelling direction; Chaufeur is finished the entire job process in the driver's cab operation.
Among Fig. 2, electrical motor (9) drives retarder (11), by two plunging joints (12), drives two and overlaps reel (14) rotation that is supported on the bearing seat (13), finishes the drawing-in motion of steel rope.Whole actuating device relies on the switching of drg (10) to realize starting, the braking of system.
The utility model will hoist-wheeling mechanism is integrated, and is placed on simultaneously on the doorframe crossbeam, reduced the weight of running trolley effectively, reduced equipment manufacturing cost simultaneously in design.
Among Fig. 3, container spreader (4) is when rising to certain position, bump against steel wire after, walk around pulley (15) and drive travel switch (18) action, realize hoisting spacing purpose.Pulley is connected on the link span (17) by sheave shaft (16), is fixed on portal-framed structure; Container spreader drops to spacing when following, and the spacing steel wire of clump weight (19) pulling is got back to level attitude.
Among Fig. 4, crotch (23) uses flange to be connected with portal-framed structure, by cart operation actuating device (1) tire on the drive wheels assembly (20), realizes the cart operation of complete machine; Guardrail (21) is used to protect tire assembly etc. not damaged by outside other object collision; (22) are supported in the fork protection is the particular design of this light tyre formula transfer crane, if can at first land behind the unexpected tire flat, prevents that complete machine from toppling.
