Abstract

The utility model discloses a transverse moving device of a crane, which adopts the following structure: each horizontal landing leg assembly of the crane is provided with a lower roller set and an upper roller set, the lower roller set is arranged inside the rear end of a horizontal moving leg, and the upper roller set is arranged on the front end of a horizontally fixed sleeve leg; the upper roller set and the lower roller set have the same structure and are both connected with a framework through screw threads by pressing bolts, the pressing bolts are connected with a pressing board in a sleeved way, the pressing board is adhered to a bearing bush which is adhered to a rolling rod, the rolling rod is positioned in the framework, and the bearing bush is fixed on the framework through bolts; the rolling rod of the lower roller set can roll on the inner surface of a lower frame of the horizontally fixed sleeve leg; and the rolling rod of the upper roller set can roll on the upper surface of an upper frame of the horizontal moving leg. When the crane cannot be driven to working objects, vertical landing legs are put up, the horizontal landing legs are stretched under operation, and the crane is led to slide on the horizontal landing legs through the upper roller set and the lower roller set, thus leading the crane to move transversely to a working surface and implement the hoisting operation. The transverse moving device of the crane has simple structure, reasonable design and strong practicability.

Description

The crane horizontal mobile device

Technical field

A kind of additional device of crane, particularly a kind of crane horizontal mobile device.

Background technology

Crane is before operation, because a lot of reasons such as road is narrow or operation place (road surface, building) undesirable, crane occurring can't be near hanging object under the situation that normal turn is travelled, thereby affects the work adversely through regular meeting.Meet this situation or the row construction again of trimming place, perhaps use large tonnage crane instead and lift article at a distance, cause the waste of recruitment unit like this.

Summary of the invention

The purpose of this utility model is to provide a kind of crane horizontal mobile device.Crane horizontal mobile device of the present utility model can make the crane car body move by the axletree direction of crane horizontal mobile device along crane.

The purpose of this utility model can realize.The utility model is that the crane to prior art improves and is achieved.The crane horizontal mobile device is characterised in that: roller groups on a following roller groups and all is being housed on each horizontal support legs assembly of crane.Following roller groups is contained in the inside of horizontal anomalous movement leg rear end, last roller groups be contained in horizontal fixed cover leg front end above.Following roller groups is threaded with framework by push bolt, push bolt and pressing plate socket, pressing plate and bearing shell are fitted, bearing shell and roller are fitted, roller places framework, have the roller groove on the lower frame of horizontal anomalous movement leg, roller is fitted by the inside face of roller groove and horizontal fixed cover leg lower frame, and bearing shell is formed by being bolted on the framework.Last roller groups is threaded with framework by push bolt, push bolt and pressing plate socket, pressing plate and bearing shell are fitted, bearing shell and roller are fitted, roller places framework, have the roller groove on the horizontal fixed cover leg front end upper ledge, roller is fitted by the upper surface of roller groove and horizontal anomalous movement leg upper ledge, and bearing shell is formed by being bolted on the framework.The roller of following roller groups has a straight-line rolling track on the inside face of horizontal fixed cover leg lower frame.The roller of last roller groups has a straight-line rolling track on the upper surface of horizontal anomalous movement leg upper ledge.

Crane horizontal mobile device of the present utility model is simple in structure, reasonable in design, practical.It has solved crane when opening less than the scope of operation, relies on vertical leg and horizontal support legs that crane is moved laterally to the problem that the scope of operation can lift.

The specific embodiment

Referring to Fig. 1, Fig. 2.Crane horizontal mobile device of the present utility model is the improvement to existing crane.On four horizontal support legs assemblies of crane 1, all adorn a following roller groups 3 and a last roller groups 5 on each horizontal support legs assembly.Full car is equipped with four following roller bearings 3 and four altogether and goes up 5 groups of roller groups.Following roller groups 3 is identical with the structure of last roller groups 5, only is that installation is different with the position that cooperates.With the right side is example, referring to Fig. 3, Fig. 5.Following roller groups 3 is welded on the inside of right horizontal anomalous movement leg 7 rear ends, last roller groups 5 be welded on right horizontal fixed cover leg 10 front ends above.Referring to Fig. 4, Fig. 5, Fig. 6.Following roller groups 3 is threaded with framework 12 by push bolt 11, push bolt 11 and pressing plate 13 sockets, pressing plate 13 is fitted with bearing shell 14, bearing shell 14 is fitted with roller 15, roller 15 places framework 12, have roller groove a on the lower frame of right horizontal anomalous movement leg 7, roller 15 is fitted by the inside face of roller groove a and right horizontal fixed cover leg 10 lower frames, and bearing shell 14 is fixed on the framework 12 by bolt 16 to be formed.Following roller groups 3 is welded in the lower frame of right horizontal anomalous movement leg 7.Last roller groups 5 is threaded with framework 12 by push bolt 11, push bolt 11 and pressing plate 13 sockets, pressing plate 13 is fitted with bearing shell 14, bearing shell 14 is fitted with roller 15, roller 15 places framework 12, have roller groove b on the right horizontal fixed cover leg 10 front end upper ledges, roller 15 is fitted by the upper ledge surface of roller groove b and right horizontal anomalous movement leg 7 upper ledges, and bearing shell 14 is fixed on the framework 12 by bolt 16 to be formed.The roller 15 of following roller groups 3 can roll on the inside face of right horizontal fixed cover leg 10 lower frames.The roller 15 of last roller groups 5 can roll on the upper surface of right horizontal anomalous movement leg 7 upper ledges.

Referring to Fig. 1, Fig. 4, Fig. 7 and Fig. 8.Before the crane operation, meet narrow, the non-removable obstacle of road, muddy unequal reason, cause crane then crane to be reached the place of the most close operation thing near by the operation thing time, and with vehicle body vertically towards hanging object, park.At this moment, move joystick 2, make ACTUATOR 9 work; Push bolt 11 is tightened, roller 15 and rolling surface are fitted, handle the work of crane side travel.Step is as follows: 1. left horizontal anomalous movement leg 17 is stretched out fully, right horizontal anomalous movement supporting leg 7 is regained fully; 2. both sides are all

vertical leg

6,8 are put down, and make crane wheel 4 built on stilts; 3. simultaneously left horizontal anomalous movement supporting leg 17 is regained, right horizontal anomalous movement supporting leg 7 is stretched out, crane 1 is moved to left to the limit on left and right movable supporting

legs

17,7 by the rolling of upper and lower roller groups 5,3.4. both sides are all

vertical leg

6,8 are packed up, and make crane wheel 4 support ground; 5. carry out 1. repeatedly, 2., 3., 4. four kinds of operations, can to hanging object, carry out lifting operation with crane is traversing.

After the crane side travel finishes, push bolt 11 is all unclamped.Push bolt uses during only for the crane side travel.

The utility model comprises that employing changes material between movable leg and fixed cover leg, strengthens the design of wear resistance between the movable part.
