Abstract
The utility model discloses a pin shaft connection device of an inner climbing belt of a tower crane. The pin shaft connection device comprises pin hole ear plates, pin shafts, a conversion position plate, shaft end baffle plates and pin shaft baffle plates, wherein pin shaft holes are formed in the middles of the pin hole ear plates; the two pin hole ear plates are correspondingly welded on a climbing beam; the pin shafts pass through the pin hole ear plates; one ends at the outer sides of the pin shafts are fixed on the pin hole ear plate at the outer side through the shaft end baffle plates; the cantilever ends at the inner sides of the pin shafts are connected with the conversion position plate and fixed on the conversion position plate through the pin shaft baffle plates; the conversion position plate is connected with the climbing belt; grooves are formed in two ends of each pin shaft; a shaft end baffle plate groove passing through a shaft center is formed in the shaft end at one end of each pin shaft and is fixed with each shaft end baffle plate in a matching manner through bolts; a shaft pin baffle plate groove is formed in the shaft end at the other end of each pin shaft and is fixed with each pin shaft baffle plate in the matching manner through the bolts. The shaft end baffle plates are mounted at two ends of the pin shafts, so that the function of circumferential fixation is realized. Thus, the pin shaft connection device can be conveniently assembled in a positioning manner when being assembled. The pin shafts are fixed circumferentially, so that the lateral swing of the climbing belt, which is caused by the circumferential rotation of the pin shaft, is difficult to generate. As a result, the use safety of the climbing belt is improved.
Description
Technical field
The utility model relates to a kind of pin shaft connecting apparatus, particularly climbs the pin shaft connecting apparatus of band in a kind of tower crane.
Background technology
At present, the beam that climbs of climbing tower crane is followed to climb and is with while by bearing pin, connecting, and generally there will be to install and wear axle process difficulty, and easily situation inaccurate, that affect job safety is located in appearance.
The utility model content
Technical problem to be solved in the utility model is the problem that exists for prior art, and a kind of climb beam and pin shaft connecting apparatus of climbing band that location is convenient, use safe inner climbing type hoisting crane of installing is provided.
for solving this technical matters, the utility model provides the pin shaft connecting apparatus of climbing band in a kind of tower crane, comprise the pin-and-hole otic placode, bearing pin, the conversion arm-tie, axle end baffle plate and pin shaft baffle, the middle part of described pin-and-hole otic placode is provided with pin shaft hole, two pin-and-hole otic placodes are welded on the beam that climbs relatively, described bearing pin passes the pin-and-hole otic placode, its outside one end makes and is fixed by bolts on the pin-and-hole otic placode of the outside by axle end baffle plate, its inboard cantilever end is connected with the conversion arm-tie, make and be fixed by bolts on the conversion arm-tie by pin shaft baffle, described conversion arm-tie with climb the band be connected.
Described bearing pin two ends fluting, one end axle head was provided with the axle end baffle plate groove in axle center, was used in conjunction with bolt with axle end baffle plate and fixed, and its other end is provided with the pin shaft baffle groove, is used in conjunction with bolt with pin shaft baffle and fixes.
Beneficial effect: the utility model compared with prior art,, because all there is axle end baffle plate at the bearing pin two ends, has played circumferential fixation, so the installation process location and installation is convenient; In operation process, circumferentially fixing because of bearing pin, be not prone to that bearing pin circumferentially rotates and the band side on oscillation situation of climbing that causes reaches and improves the purpose of using safety.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is pin shaft structure schematic diagram of the present utility model;
Fig. 3 is axle end baffle plate scheme of installation of the present utility model;
Fig. 4 is the view of installing and using of the present utility model.
In figure: 1 climbs band pin shaft connecting apparatus, 2 beam, 3 that climbs climbs band, 4 pin-and-hole otic placodes, 5 bearing pins, 7 and changes arm-ties, 8 axle end baffle plates, 9 pin shaft baffles, 10 axle end baffle plate grooves, 11 pin shaft baffle grooves.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is done specific descriptions.
Figure 1 shows that structural representation of the present utility model.
The utility model comprises pin-and-hole otic placode 4, bearing pin 5, conversion arm-tie 7, axle end baffle plate 8 and pin shaft baffle 9.
The middle part of described pin-and-hole otic placode 4 is provided with pin shaft hole, and two pin-and-hole otic placodes 4 are welded on the beam 2 that climbs relatively.
Figure 2 shows that pin shaft structure schematic diagram of the present utility model.
Described bearing pin 5 two ends flutings, one end axle head was provided with the axle end baffle plate groove 10 in axle center, with axle end baffle plate 8, coordinated circumferentially and fixed; Its other end is provided with pin shaft baffle groove 11, with pin shaft baffle 9, coordinates circumferentially and fixes.
Described bearing pin connection mode is cantilever design, and bearing pin 5 passes pin-and-hole otic placode 4, and its outside one end is used in conjunction with bolt by axle end baffle plate 8 and axle end baffle plate groove 10 and fixes (as shown in Figure 3); Its inboard cantilever end is connected with conversion arm-tie 7, is used in conjunction with bolt by pin shaft baffle 9 and pin shaft baffle groove 11 and fixes.
Figure 4 shows that the view of installing and using of the present utility model.
Described conversion arm-tie 7 is with 3 to be connected with climbing.
During use, bearing pin 5 passes two pin-and-hole otic placodes 4, cantilever end at bearing pin 5 hangs up conversion arm-tie 7, be provided with axle end baffle plate 8 and pin shaft baffle 9 at the two ends of bearing pin 5, behind the position of good bearing pin 5 to be determined and conversion arm-tie 7, the axle end baffle plate 8 at bearing pin 5 two ends and pin shaft baffle 9 are fixedly connected with conversion arm-tie 7 with pin-and-hole otic placode 4 respectively, thereby play the effect of the axial restraint of axle; To climb finally and be with 3 with conversion arm-tie 7, to be connected.
The utility model compared with prior art,, because all there is axle end baffle plate at the bearing pin two ends, has played circumferential fixation, so the installation process location and installation is convenient; In operation process, circumferentially fixing because of bearing pin, be not prone to that bearing pin circumferentially rotates and the band side on oscillation situation of climbing that causes reaches and improves the purpose of using safety.
