Description
Technical field
The utility model belongs to weight-lifting equipment manufacturing technology field, is specifically related to a kind of walking bottom girder, particularly relates to a kind of low clearance walking bottom girder.
Background technology
Walking bottom girder designed is in the prior art generally regular rectangular beam structures, due to rectangular beam structures entirety linearly structure, after its two ends install traveling gear additional, at least 0.8m is increased to bottom girder, therefore certain influence is caused to the working space of weight-lifting equipment, the general employing with walking bottom girder of its support beam of existing weight-lifting equipment is welded to connect on the other hand, and be welded to connect must specialty welding technician install on the spot, operation requirements is higher.
Summary of the invention
For solving problems of the prior art, the application provides a kind of low clearance walking bottom girder that can solve prior art.
Technical solution adopted in the utility model is as follows: a kind of low clearance walking bottom girder, include girder, the support beam connection structure that upper surface, girder two ends is arranged and the walking connection structure being arranged at lower surface, girder two ends, the overall rectangle steel structure for being welded of described girder, concave configuration is provided with in the middle of described girder, its overall formation two ends are high, middle recessed curved structure, wherein corresponding with the concave surface of girder concave configuration girder lower surface forms bulge-structure, described support beam connection structure includes the butt flange that is arranged at its upper surface and the brace panel for strengthening, described walking connection structure includes and is arranged at two the pin sheets of girder with the left and right sides, one end, and the interspersed bearing pins be fixed between two pin sheets.
Described butt flange is rectangular shaped rim structure, and is equidistantly evenly provided with butt hole on its border structure.
Described butt hole is provided with at least 4 in the every bar rectangular edges of butt flange.
The beneficial effect that this programme embodies is: be middle concave configuration by main beam design, can ensure that girder downside and ground are more close after the installed rows walking apparatus of girder two ends, 2m is can reach according to its recessed amplitude of distinct device model, therefore the working space of weight-lifting equipment has greatly been saved, winch can be made less merit is done when hoisting heavy, therefore greatly saved energy consumption, and made lifting space more abundant; The brace panel be surrounded on around support beam connection structure is added when support beam connection structure is connected with girder on the other hand, that connection between support beam connection structure and girder is more firm, wherein support beam connection structure upper end is designed to the butt flange that can carry out screw docking, each rectangular edges of butt flange arranges at least 4 butt holes, thus solve the problem of support beam connection inconvenience, common employee can be realized can install support beam, reduce the degree-of-difficulty factor of installation; Walking connection structure adopts the unitized construction of pin sheet and bearing pin, makes the installation of running gear and disassembles convenient.Total the utility model has easy for installation, that operational space is sufficient advantage.
Accompanying drawing explanation
Fig. 1 is integral structure front elevation of the present utility model.
Fig. 2 is integral structure birds-eye view of the present utility model.
Fig. 3 is integral structure left view of the present utility model.
In figure: 1, girder 2, support beam connection structure 3, connection structure 4, concave configuration 5, bulge-structure 6, butt flange 7, brace panel 8, pin sheet 9, bearing pin 10, butt hole.
Detailed description of the invention
According to embodiment, scheme of the present utility model is described further below.
Embodiment 1: as shown in Fig. 1-3, a kind of low clearance walking bottom girder, include girder 1, the support beam connection structure 2 that upper surface, girder 1 two ends is arranged and the walking connection structure 3 being arranged at lower surface, girder 1 two ends, the described rectangle steel structure of girder 1 entirety for being welded, concave configuration 4 is provided with in the middle of described girder 1, its overall formation two ends are high, middle recessed curved structure, wherein corresponding with the concave surface of girder 1 concave configuration 4 girder 1 lower surface forms bulge-structure 5, described support beam connection structure 2 includes the butt flange 6 that is arranged at its upper surface and the brace panel 7 for strengthening, described walking connection structure 3 includes and is arranged at two the pin sheets 8 of girder 1 with the left and right sides, one end, and the interspersed bearing pins 9 be fixed between two pin sheets 8.
Described butt flange 6 is rectangular shaped rim structure, and is equidistantly evenly provided with butt hole 10 on its border structure.
Described butt hole 10 is provided with 5 in the every bar rectangular edges of butt flange 6.
The utility model is in use: first need to install additional support beam and top end rail, and end positions installs running gear additional bottom girder, when support beam is installed, the butt flange of the plain flange of the lower end of support beam with support beam connection structure is docked, and use screw that two butt flanges are carried out contraposition to fix; Running gear is installed on bearing pin and is fixed; Girder downside after installation and ground distance less, thus enough lifting spaces can be ensured when weight lifts by crane; The support beam connection structure that this programme adopts is flange connection, and more traditional welding process saves time more, less manpower, and adopts bearing pin to be connect to the connection of running gear, makes it install and disassembles convenient.Wherein in butt flange every bar rectangular edges, being provided with 5 butt holes makes the connection between butt flange more firm.
Total the utility model has advantage that is easy for installation, lifting space foot.
