Detailed Description
In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the embodiments of the present invention are combined to carry out clear and complete descriptions on the technical solution in the embodiments of the present invention, and obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. Based on the embodiment of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 5, the embodiment of the present invention discloses a track joint structure of a monorail crane, which comprises a front track 1, a rear track 2, a connecting lug 3, a plug board connecting lug 4, a lug 5, a plug board 6, a connecting hanging plate 7, a buffer structure 8, a pin shaft 9, and an arch-shaped hanging ring (not shown).
Preceding track 1 links up with back track 2 end to end, and two connect the lug 3 and set up relatively and weld the top surface at preceding track 1, and picture peg connection lug 4 welds the top surface at back track 2, and picture peg connection lug 4 inserts between two connection lugs 3.
The pin shaft 9 penetrates through the two connecting lifting lugs 3 and the inserting plate connecting lifting lug 4, the inserting plate connecting lifting lug 4 is rotatably connected with the two connecting lifting lugs 3 through the pin shaft 9, two ends of the pin shaft 9 are fixedly connected with two ends of the arched lifting ring respectively, and the arched lifting ring is used for hanging a rail.
The inserting plate 6 is fixedly connected to the bottom of the front rail 1, the connecting hanging plate 7 is fixedly connected to the bottom of the rear rail 2, a clamping groove structure corresponding to the inserting plate 6 is arranged on the connecting hanging plate 7, the inserting plate 6 is clamped into a clamping groove of the connecting hanging plate 7 to form a locking structure, the lower portions of the front rail 1 and the rear rail 2 are connected together, and stability of a joint of the monorail crane is improved.
When the installation is carried out, the front track 1 and the rear track 3 are butted end to end, and the inserting plate connecting lifting lugs 4 are inserted between the two connecting lifting lugs 3 to ensure that the pin shaft holes are concentric; then the inserting plate 6 is clamped into the clamping groove of the connecting hanging plate 7 to be locked; after locking, the disc spring is arranged between the two sides of the inserting plate connecting lifting lug 4 and the two connecting lifting lugs 3 and is fixed by a pin shaft 9 penetrating through the connecting lifting lugs 3, the inserting plate connecting lifting lug 4 and the disc spring.
The working principle is as follows: under the conditions such as heavy load, heavy grade, complicated operating mode, because track installation error, there is the declination between preceding track 1 and the back track 2, the maximum value is 1, this makes also no longer parallel between pull rod and the track, consequently the pull rod will produce a yawing force to the track through the drive division, this yawing force will produce a plurality of moments of torsion to the track with the thrust that the below track transmitted, the track left and right rocking when making single track hang the operation, when drive power is very big, can cause the track to become invalid even. The utility model discloses design buffer structure 8 between lug 3 is connected in picture peg 4's both sides and two, play the buffer protection, increase lifting surface area, reduce the effect of impact, when the relative dislocation of track emergence behind the present, the pull rod can not produce the rigidity collision of picture peg connection lug 4 and connection lug 3 immediately to orbital lateral force, rocks about the track is relative around making and has been alleviated to a certain extent, has avoided the track atress unreasonable and lead to track inefficacy. Under the working conditions that the load is larger and the gradient is larger, the required driving force is larger, and at the moment, the number of disc springs of the buffer structure 8 can be properly increased so as to improve the strength of the rail joint. The disc spring at the joint of the rail is inspected and replaced regularly, and the disc spring can be replaced when damaged.
