Claims (2)

The invention relates to the field of cranes, mainly to control cabins of gantry cranes. The cab of a goat crane, containing a frame with panels and glazing, fastening elements to the crane support, and an entrance platform with a fence 1, is known. A disadvantage of this design of a goat crane control cabin is the layer of the eight-sided frame structure and panels stand, swivel control panel and the seat of the machinist. a large coherence of shading posts in the frame, unsatisfactory side-view conditions j of a fixed platform, which require, due to this, its constant intensive rotation in both directions in accordance with the need for a steady wide view of the lifting and lowering zones and horizontal movement in mutually perpendicular directions of the cargo cart with cargo along the crane bridge and movement of the crane itself along the rails of the crane track. Due to the specific shape of each face, the review in the vertical plane is unsatisfactory, especially in the lower zone due to shading by the floor and the platform. Because of the constancy of the position of the platform axis with the machinist relative to the crane supporting structures, the space behind these structures is a dead zone, inaccessible to observation. These disadvantages reduce the convenience of the driver and the performance of the crane. It is also difficult to enter such a cabin and its equipment with various equipment and devices (heaters, indicators, switchboards, cabinets, wall lights, etc.) that are necessary for a gantry crane. The purpose of the invention is to simplify the design of the cab and increase the convenience of the machine. it is fixed on the crane support and is made as a part of a circle with the center on the vertical axis, and the fencing contains separate sliding circular sections from which it is internally fixed to the entrance on the platform, and outside - on the cabin, and every year it is provided with a position lock. In addition, the cabin can be equipped with a rotation drive around a vertical axis with control inside the cabin. fla FIG. 1 shows a control cabin mounted on a rigid support of the gantry edge Hia (side view); in fig. 2 - the same, in a perspective view; in fig. 3 - the same, in plan, in the position along the rail tracks of the crane (across the flute structure); in fig. 4 - the same, in iDiaHc, in a position beneath the flap to the rail tracks of a crane; in fig. 5 - the same in plan, in position across the rail tracks of the crane and along the span of the crane; in fig. 6 - the same, in plan, two extreme positions of the cabin, providing full all-round visibility through the front and side glazing; in fig. 7 is a schematic diagram of the installation of the cabin and fences; in fig. 8 — node I in FIG. 7; in fig. 9 is a diagram of a cab suspension on a vertical axis with a cornering drive.,. The control cabin 1 is mounted on a rigid support 2 of the gantry crane (Fig. 1) with the ability to observe the movement of the cargo carriage 3 along the span 4, the movement of the undercarriage 5 but the rail track 6, as well as the vertical movement of the lifting device 7. Cabi1 and 1 has a frame 8 with panels 9 and a glazing 10 (Fig. 2). On the vertical edge 11 of the frame, the upper and lower krtnshteins 12 and 13 are mounted, working in pairs with the corresponding brackets 14 and 15 of the rigid support 2, mounted coaxially on the vertical axis 16, which is the axis of rotation of the cab 1 (Fig. 3). The entrance to the cabin is made from the entrance gate 17, the safety of which is provided by the fence 18, consists of two mutually sliding circular inner sections - 19 and outer 20 (Fig. 7). The inner section 19 is fixed to the entrance area, and the outer section 20 is suspended with racks 21 to cab bracket 22, forming an awning shape 23 with free passage under it (Fig. 2). Both sections and the platform 17 are made crooked with the center on the axis 16 (Fig. 3, 4, 5). Cab 1 is arranged in horizontal form by rotating around axis 16 and can occupy various positions, including along the track 6 and across the span 4 (Fig. 3), at an angle to the directions of movement of the undercarriage 5 and the trolley 3 (Fig. 4) and along the span 4 transversely to the track 6 (Fig. 5), with y: Ke within the angle of rotation / 3 90 ° (Fig. 6) free visibility is ensured through the glazing 10 of the entire crane working area by 360 °, including visibility along the crane path and along the path and cargo carriage within the span, and the console departures. In any working position, the cabin can be fixed by the latch 24 (Fig. 8). The axis of rotation 16 can be kinematically connected with the brackets P and 13 of the cab — one side, and with the drive 25 (FIG. 9) on the other, with the transmission of torque for steering, saber from the driver’s workplace. The gantry crane cab operates in the following manner. Installed on a rigid support 2 cabin 1 orientation and side of the production of works or movement of the crane. With a large variety of working movements, the crane, the trolley, and the lifting device all move during their working cycles along their trajectories in certain working areas that should be accessible: they are easy to see. Depending on the prevailing direction of movement of the cargo and the crane, as well as on the direction of the cargo flow of loading, unloading, feeding or storing cargo, the cabin; by turning on the J6 axis, be most favorably oriented to the zone of greatest danger, or more intensive traffic, which reduces driver fatigue, shortens the time of the working cycle and increases the productivity of work when cracking and usability on it. In addition, all normally inaccessible areas (in the area of the rear console, behind a rigid support to the like) are easily observed when there is a tight turn of the cab. In any position of the cabin, the convenience and safety of the entrance to it, as well as being at the entrance platform, is preserved, since the cabin fences constantly shield the closed area of two concentric sections. The latch 24 presses the movement of the cab, and the actuator 25 controls the rotation from the cab, from the working place of the vehicle. Claim 1. Cabin control goat crane, containing a frame with panels and glazing, fastening elements to the crane support and entrance platform with a fence, characterized in that, in order to simplify the design and enhance the usability of the machinist, the fastening elements contain at least At least two pairs of brackets mounted respectively on the crane support and outside on the vertical edge of the cabin frame and articulated in pairs in a vertical axis, the entrance platform is fixed on the crane support 96 and is part of a circle centered on the said vertical axis; and the enclosure comprises mutually sliding circular sections, of which is internally fixed at the entrance platform, and external - at the cabin, the latter being provided with a position lock. 2. The cabin according to claim 1, characterized in that it is provided with a rotational drive around a vertical axis with control inside the cabin.
