Description

FIELD OF TECHNOLOGY

The claimed device relates to the construction of gantry cranes, in particular, to the modular construction of the gantry crane.

LEVEL OF TECHNOLOGY

An example of a modular crane design is known from the prior art (RF patent No. 2503611, 01/10/2014). The known construction of a gantry crane is a collapsible superstructure with a telpher, assembled into a single whole from several parts of a tubular, frame, I-beam or other section, each of which has elements at the ends for their connection, for example, flanges or brackets with bolts or studs; four height-adjustable support posts on rail wheels, connected in pairs at the base by a tie beam, converging to the superstructure and fastened to each other, for example, using fingers in the lugs made at the upper ends, and to the superstructure, to its projecting horizontal longitudinal flanges , with the help of clamps with bolts and nuts in any place, thus providing the opportunity to have any necessary adjustable width of the span, consisting of two parts, in order to adjust the height, overlapping or telescopically connected to each other, having appropriate fastening and fixing elements by themselves, as an option, the upper and lower welded frames of the same width with side members, cross members and braces from a bent channel, the side members of which in the overlap gap are fastened, for example, by ladders and pins, the lower frames have trolleys with wheels and fastening elements of the tie beams, and the upper frames have the aforementioned elements, with tying them together and the superstructure; crane scaffolds consisting of vertical struts of arbitrary section with nuts or fittings welded at the ends and screwed in the lower part of the screw supports with locknuts and thrust bearings, and carrying longitudinal and transverse beams fixed to them, as an option, with the help of ladders, horizontally located of arbitrary section , with crane runways mounted on transverse beams, characterized in that it contains a collapsible superstructure, anchoring of support posts to the superstructure, which allows adjusting the width of the span, height-adjustable support posts, crane scaffolding.

The disadvantage of this design is the complexity of its installation and adjustment, as well as insufficient efficiency in the formation of the required span size while maintaining the stability of the entire crane structure. Also, adjusting the span by changing the height of the overlapping or telescopic racks is not possible when using a double-girder box-section crane, which limits the possible implementation of the crane and its lifting efficiency.

ESSENCE OF THE USEFUL MODEL

To solve the technical problem in terms of creating an efficient crane design that provides simple and quick adjustment of the span and lifting height, a new gantry crane design is proposed.

The technical result consists in increasing the efficiency of the use of lifting equipment, due to the implementation of the bridge track and supports modular.

An additional effect is to expand the arsenal of technical means, in particular, gantry cranes, as well as to increase the speed and ease of adjusting the span and lifting height of the crane.

The claimed technical result is achieved due to the design of a modular gantry crane containing a span, four support legs mounted on wheel blocks, a lifting mechanism located on a cargo trolley capable of moving along a bridge track, a control cabin, characterized in that the span is formed by two beams bridge track, the wheel blocks are equipped with a movement mechanism, while two support legs are rigid, and the other two are flexible, and the support legs and the bridge track are modular and each rack contains one removable module, and each of the bridge track beams has two removable modules , while the modules are made of box section and contain fixation elements.

In one example of a crane implementation, the girders of the bridge track are box-shaped.

In another embodiment of the crane, the bridge track modules additionally contain fixation elements reinforced with fasteners.

In another embodiment of a crane, the hoisting mechanism is an electric winch.

IMPLEMENTATION OF THE USEFUL MODEL

As shown in FIG. 1, the construction of the proposed gantry crane (10) consists of two girders (101, 102), which are preferably box-section. The beams (101, 102) form a bridge path along which a means of lifting loads (108), for example, a load carriage containing an electric winch, moves. The bridge track rests on the crane track with four support legs (103, 104, 106, 107). The uprights (103, 104) are flexible, connected to each other by means of tie beams (109), and the posts (106, 107) are rigid, connected in the upper part by a portal (111) and tie beams (110, 111). Support legs (103, 104, 106, 107) are mounted on wheel blocks (105), equipped with a movement mechanism, ensuring the movement of the crane (10) around the construction site. The crane (10) is controlled through a control cabin containing the necessary controls (not shown in Fig. 1).

The main characteristics of the crane are its lifting capacity, span (distance between the rails of the crane track), lifting height. The beams (101, 102) forming the crane bridge (10) and the supports (103, 104, 106, 107) are made of modules (1011/1012, 1012/1022, 1031/1041, 1061/1071), which allow achieving different indicators the main characteristics are crane span and lifting height.

The principle of removing / installing modules is shown in FIG. 2. In a complete set of modules, the crane (10) has a span of 36 m and a lifting height of 25 m. Each support leg (103, 104, 106, 107) contains one module (1031, 1041, 1061, 1071). It should be noted that the example with paired removal of modules (1031, 1041) is an example and does not have to be done in this way. Removal of the rack modules (1031, 1041) can be done one at a time. The bridge track contains two modules (1011, 1012, 1021, 1022) on each of the beams (101, 102).

FIG. 3 shows an example of a bridge section module (1011). The removable modules of the bridge (1011/1012, 1021/1022) and supports (1031/1041, 1061/1071) are box-section and contain fixing means (21), for example, a bolt connection or flanges that secure the modules. As shown in FIG. 3, the bridge modules (1011, 1012, 1021, 1022) additionally contain, in one of the module parts, a pair of fixing elements (22) made in the form of protrusions to fix them and provide additional rigidity. Each protrusion is additionally reinforced with fasteners (23), for example, pins or bolts.

When one crane bridge module is removed, for example, (1011/1021), the span becomes 30 m, when two modules (1011/1012 and 1021/1022) are removed, the span becomes 24 m. When the crane support modules (1031, 1041, 1061, 1071), the lifting height becomes 16 m.Various characteristics when adjusting the span size and height allow the crane (10) to be operated on different construction sites, which allows more efficient use of lifting equipment and an increase in the efficiency of the site for crane installation (10).
