Description
Technical field
The present invention relates to mechanical equipment technical field, specially a kind of hydraulic lifting gate type portal gantry.
Background technology
Important lifting equipment of the gantry crane as port and pier, is mainly engaged in the handling operation of break bulk cargo, frequently Frequency of use, higher operating rate propose very high requirement to the steel construction part of crane.The door frame of gantry crane Be top rotating part weight, lift heavy support mechanism, but also want receiving mechanism brake load and wind load, working environment and Load condition is complicated, and to ensure that crane runs well, door frame must have enough intensity, and have larger rigidity.It is existing The girder construction of gantry crane mostly formed for multilayer steel plates, dead load is big, and component production and installment work are complicated, consumption Take a large amount of man power and material, and gantry crane is in use, be susceptible to the feelings of main beam deformation after being used for a long time Condition, poor safety performance, service life is relatively low, seriously affects the operating efficiency of crane.Therefore we make this improvement, propose A kind of hydraulic lifting gate type portal gantry.
Invention content
The purpose of the present invention is to provide a kind of hydraulic lifting gate type portal gantry, to solve to carry in above-mentioned background technology The problem of going out.
To achieve the above object, the present invention provides following technical solution：A kind of hydraulic lifting gate type portal gantry, including Girder, Bailey bracket strengthen steel plate and U-type groove steel, and the first connecting plate, the first connecting plate underface are equipped at the top of the girder The second connecting plate is corresponding with, Bailey bracket, girder bottom both ends are installed between second connecting plate and the first connecting plate Stent is respectively fixed with, the stent both sides are symmetrically connected with supporting leg, and the supporting leg side is equipped with interior U-type groove steel, and supporting leg is another Side is equipped with outer U-type groove steel, is fixed with reinforcement steel plate between the outer U-type groove steel and interior U-type groove steel, the cantilever tip is equipped with Fixed plate, the second connecting plate bottom offer with the corresponding mounting groove of fixed plate, be provided with cunning between the mounting groove Slot is equipped with hydraulic elevating platform in the sliding slot, and the stent bottom end is connected with bottom end rail, is fixed among the bottom end rail Crane travel mechanism.
Preferably, it is connected between the fixed plate and mounting groove by trip bolt.
Preferably, it is fixedly connected by welding between the reinforcement steel plate and outer U-type groove steel and interior U-type groove steel.
Preferably, the stent is an integral molding structure with fixed plate.
Preferably, the stent and supporting leg are trapezoidal shape structure.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the present invention is by the first connecting plate and the second connecting plate of setting, and girder is by the first connecting plate and the second connecting plate Outer framework is formed, and Bailey bracket is installed between the first connecting plate and the second connecting plate, both instead of the main beam structure of conventional cumbersome, Frame deformation is also avoided simultaneously, is prolonged the service life.
2nd, the present invention is by the stent and supporting leg of setting, and general supporting leg is flower holder structure, load bearing effect difference and itself compared with Weight, stability is not high, this kind of door frame forms trapezoidal shape stent, and interior U-type groove steel and outer U-type groove steel quality by trapezoidal shape supporting leg It is relatively light, stable connection.
3rd, for the present invention by the bottom end rail and mounting groove of setting, bottom end rail is load-bearing basic part, is fitted with crane fortune Row mechanism makes door machine orbiting, and fixed plate is connected in mounting groove by trip bolt, and handling are convenient.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work Embodiment shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of hydraulic lifting gate type portal gantry, including master Beam 1, Bailey bracket 3 strengthen steel plate 7 and U-type groove steel 10, and 1 top of girder is equipped with the first connecting plate 2, first connecting plate 2 Underface is corresponding with the second connecting plate 6, and Bailey bracket 3, the master are equipped between 6 and first connecting plate 2 of the second connecting plate 1 bottom both ends of beam are respectively fixed with stent 15, and 15 both sides of stent are symmetrically connected with supporting leg 9, and 9 side of supporting leg is equipped with interior U-type groove steel 8, and 9 opposite side of supporting leg is equipped with outer U-type groove steel 10, is fixed with and adds between the outer U-type groove steel 10 and interior U-type groove steel 8 Strong steel plate 7,15 top of stent are equipped with fixed plate 14, and 6 bottom of the second connecting plate offers corresponding with fixed plate 14 Mounting groove 12, be provided with sliding slot 5 between the mounting groove 12, hydraulic elevating platform 4, the branch be installed in the sliding slot 5 15 bottom end of frame is connected with bottom end rail 16, and crane travel mechanism 11 is fixed among the bottom end rail 16.
It is connected by trip bolt 13 between fixed plate 14 and mounting groove 12, is dismounted convenient for door frame；Strengthen steel plate 7 and outer U It is fixedly connected by welding between type groove steel 10 and interior U-type groove steel 8；Stent 15 is an integral molding structure with fixed plate 14；Stent 15 and supporting leg 9 be trapezoidal shape structure so that door frame overall stability is strong, forms larger rigidity.
Operation principle：The present invention is used as 1 frame of girder, and first by the first connecting plate 2 and the second connecting plate 6 of setting Bailey bracket 3 between 2 and second connecting plate 6 of connecting plate is installed, both instead of 1 structure of the girder of conventional cumbersome, is also avoided simultaneously Frame deformation prolongs the service life, and bottom end rail 16 is load-bearing basic part, is fitted with crane travel mechanism 11, makes door machine edge Track is run, and fixed plate 14 is connected in mounting groove 12 by trip bolt 13, and handling are convenient, made by hydraulic elevating platform 4 For the machine lifting mechanism, running and small, traditional supporting leg 9 is shaken when lifting as flower holder structure, load bearing effect is poor and itself is heavier, Stability is not high, this kind of door frame forms trapezoidal shape stent 15, and interior U-type groove steel 8 and outer U-type groove steel 10 by trapezoidal shape supporting leg 9 Lighter weight, load are strong.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace And modification, the scope of the present invention is defined by the appended.
