Abstract

A movable single-point crane capable of rotating slung load comprises a travel mechanism capable of sliding along a guide rail, a hanger connected with the travel mechanism through a hanging plate, a hanging frame arranged below the hanger rotatably relative to the hanger, and an automatic rope guiding winch and a pulley arranged in the hanger, wherein the steel rope of the automatic rope guiding winch is connected with a heavy object to the hosted through the pulley; the pulley is arranged on the side section of the hanger; and a lock mechanism is further arranged between the hanger and the hanging frame. The utility model has the advantages that the hanging point is arranged on the side edge of the arranged and at least can horizontally rotate by 180 DEG so as to ensure that the hanging point can reach edges on both sides of the slide rail when the crane moves, thus enlarging the movement range of operation.

Description

Rotatable Mobile Single Point Hanging Crane

(1) technical field

The utility model relates to a kind of Mobile Single Point Hanging Crane.

(2) background technology

The present Mobile Single Point Hanging Crane that uses, suspension centre is located at the center of equipment, this design causes when loop wheel machine moves to the slide rail edge, because the width limitations of loop wheel machine self, suspension centre but can not arrive the edge, thereby but the coverage area of suspension centre when having limited loop wheel machine work brings some inconvenience to use.

(3) summary of the invention

In order to solve existing Mobile Single Point Hanging Crane because the suspension centre that the center caused that suspension centre is located at equipment can not move to the deficiency at slide rail edge, the utility model provides a kind of rotatable Mobile Single Point Hanging Crane, its suspension centre is arranged on the side of equipment, but and suspension centre level 180 degree rotations at least, thereby suspension centre can arrive the slide rail edge when guaranteeing that loop wheel machine moves, but the coverage area when having enlarged work.

The utility model adopts following technical scheme:

Rotatable Mobile Single Point Hanging Crane, comprising can be along the traveling gear of guide rail slip, and suspension bracket is connected with traveling gear by boatswain chair; Suspension bracket below be equipped with can with suspension bracket hanging box in relative rotation, rope arranging automatically winch, pulley are installed in the described hanging box, the steel cable of rope arranging automatically winch is walked around pulley and is connected hoisting heavy, pulley is arranged on the hanging box sidepiece; Between described suspension bracket and the described hanging box catch gear is installed also.

Further, a described hanging box and a center shaft are affixed, and described center shaft is connected with bearing seat on the suspension bracket by bearing.

Further again, described catch gear is an active grab.

Further, described active grab has four, is installed in respectively on four jiaos of hanging box.

Principle of work of the present utility model is: when the needs jenny, unclamp the catch gear on four jiaos, rotate hanging box and make suspension centre turn to towards the position of moving direction, lock catch gear again; Reverse when mobile when needs, in like manner, unclamp the catch gear on four jiaos, rotate hanging box and make suspension centre turn to reciprocal position, lock catch gear again.

The beneficial effects of the utility model are: suspension centre is arranged on the side of equipment, but and suspension centre level 180 degree rotation at least, thereby suspension centre all can arrive the edge of two wood side-guides when guaranteeing that loop wheel machine moves, but the coverage area when having enlarged work.

(5) specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Referring to accompanying drawing: rotatable Mobile Single Point Hanging Crane, comprise the traveling gear 1 that can slide along guide rail, suspension bracket 2 is connected with traveling gear 1 by boatswain chair 3; Suspension bracket 2 belows be equipped with can with suspension bracket 2 hanging box 4 in relative rotation, rope arranging automatically winch 5, pulley 6 are installed in the described hanging box 4, the steel cable 7 of rope arranging automatically winch 5 is walked around pulley 6 and is connected hoisting heavies, pulley 6 is arranged on hanging box 4 sidepieces; Between described suspension bracket 2 and the described hanging box 4 catch gear 7 is installed also, described catch gear 7 is an active grab, and described active grab has four, is installed in respectively on four jiaos of hanging box 4.

A described hanging box 4 and a center shaft 8 are affixed, and described center shaft 8 connects the outer ring of a bearing 9, and described suspension bracket is by the inner ring of bearing seat 10 connection bearings 9, thereby hanging box 4 can be rotated relative to suspension bracket 2; Center shaft 8 upper ends are provided with screw thread, and nut 11 revolves thereon in case anti-avulsion falls.

As Fig. 5, shown in Figure 6, the active grab that the utility model adopted is commercially available gauge member, comprise base 12, be hinged on spanner 13 on the base 12, with the spanner 13 pivotally attached collars 14, the collar 14 cooperates with fastener 15.

Principle of work of the present utility model is: when the needs jenny, unclamp the active grab on four jiaos, rotate hanging box and make suspension centre turn to towards the position of moving direction, lock active grab again; Reverse when mobile when needs, in like manner, unclamp the active grab on four jiaos, rotate hanging box and make suspension centre turn to reciprocal position, lock active grab again.

The described content of this specification sheets embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
