Abstract

The utility model discloses a movable cantilever crane which comprises a base, a column which is vertically fixed above the base, a cable drum, a cantilever, an electric chain hoist and a movable trolley arranged under the base. The movable trolley comprises a trolley frame, a plurality of pairs of universal wheels arranged at the bottom of the trolley frame, a handrail fixed at the upper end of the trolley frame and a belt break universal wheel arranged at one end of the trolley frame, the base is fixed in the middle of the trolley frame, the plurality of the pairs of the universal wheels and the upper side of the belt break universal wheel are hinged with the trolley frame respectively, the lower side of the universal wheel is supported on the ground to from a plurality of support points for stabilizing the crane. The movable cantilever crane can move and rotate in all directions, the shifting is convenient, the crane is convenient, rapid and efficient to use, the work range is wide, and the utilization ratio is improved apparently.

Description

Portable jib crane

Technical field

The utility model relates to a kind of small-sized boom crane, and especially a kind of movably boom crane belongs to the weight-lifting equipment technical field.

Background technology

The electric chain hoist that cantilever derrick generally includes the cantilever that is installed in ground column, an end and is fixed on the column upper end, slidably be connected with cantilever and electrical control part etc., cantilever derrick is with its simple in structure, easy to use being widely used, and its shortcoming is that the work area is less.Because column fixes on the ground, it is the circumference of radius to the column center that the operating range of cantilever derrick also just is fixed on the electric chain hoist lifting center that is positioned at the cantilever distal-most end relatively, when the needs lifting exceeded the weight of above-mentioned circumference range, existing cantilever derrick can't be realized lifting.

Summary of the invention

The purpose of this utility model provides that a kind of simple in structure, range of use is wide, the portable jib crane of convenient and efficient.

The utility model is achieved by the following technical programs:

A kind of portable jib crane, comprise base, be vertically fixed on the column of base upside, be fixed on the cable drum of column middle part one side, one end and the cantilever of column upper end captive joint and the electric chain hoist that slidably is connected with the cantilever downside, also comprise the travelling car that is arranged on the base below, described travelling car comprises vehicle frame, be arranged on the several to cardan wheel of bottom of frame, be fixed on handrail and the band brake cardan wheel that is arranged on vehicle frame one end on vehicle frame one end, described base is fixed on the vehicle frame middle part, several hinged with vehicle frame respectively to cardan wheel and band brake cardan wheel upside, the cardan wheel downside supports on the ground, consists of a plurality of strong points of stablizing hoisting crane.

The utility model is set up travelling car below common cantilever derrick base, when operating range need to be adjusted, can promote travelling car, the utility model is transported to required work-yard, but the utility model all-around mobile and rotation, displacement is convenient, and is easy to use efficient, operating range is wide, has significantly improved degree of utilization.

Advantage and disadvantage of the present utility model will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiment only provide as an example with reference to accompanying drawing.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with the embodiment of accompanying drawing and miniature movable type boom crane, the utility model is described in further detail.

Present embodiment comprises base 1, be vertically fixed on the column 2 of base 1 top, be weldingly fixed on the cable drum 3 in left side, column 2 middle parts, cantilever 4 that left end is captiveed joint with column 2 upper ends and can be along the electric chain hoist 5 of 4 times Slideslips of cantilever, cable drum 3 can be rolled up payout, guarantees long distance power supply.Prepare the weight limitor that hoists on the electric chain hoist 5, guarantee the safety and stability of hoisting crane.Base 1 below is provided with travelling car 6, travelling car 6 comprises vehicle frame 61, be arranged at least two pairs of bottom, vehicle frame 61 two ends totally 4 cardan wheels 62, by a plurality of band brake cardan wheels 64 that are bolted to the handrail 63 of vehicle frame 61 afterbody upsides and are arranged on vehicle frame one end, base 1 is fixed on vehicle frame 61 middle parts by binding bolt, when the needs long distance transportation, base 1 can be removed, be convenient to transportation.4 cardan wheels 62 and band brake cardan wheel 64 support the utility model on the ground, and cardan wheel 62 can 360 ° of rotations, and band brake cardan wheel 64 is used for turning to of vehicle frame 61.Band brake cardan wheel 64 comprises brake holder 642 and the braking cardan wheel 643 that connecting panel 641 that right-hand member and vehicle frame 61 afterbodys are welded and fixed, upper end and connecting panel 641 are hinged, braking cardan wheel 643 is arranged in the brake holder 642, hinged by bearing pin and brake holder 642, brake holder 642 outer ends are provided with resilient pedal 644.During braking, pin is stepped on resilient pedal 644, and resilient pedal 644 inboards are resisted against on braking cardan wheel 643 outer rims, and braking cardan wheel 643 obtains braking, it is mobile that travelling car 6 stops, and the inertia after avoiding the utility model of large quality to stop moves the potential safety hazard of bringing.

In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
