Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.A lot of detail has been set forth so that fully understand the utility model in description below.But the utility model can be implemented to be much different from other modes described here, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
Contriver of the present utility model finds, in the connection mode of traditional girder and end wheel carrier, the friction force that the shearing force between girder and end wheel carrier only relies on the fastening effect of bolt to produce maintains.Therefore, there is the risk being born this shearing force when bolt slides lax by it.When bolt can not bear this shearing force completely, serious consequence may be produced.Therefore, existing connection mode not safe enough, the combination of existing dependence friction force needs to improve based on safety factor in other words, and this likely causes the increase of part dimension, and then improves the manufacturing cost of hoisting crane.
In the embodiment that the utility model provides, end wheel carrier is provided with outstanding ledge structure in the one side of girder, for placing girder and at least bearing the shearing force between the girder of a part and end wheel carrier, thus improves the safety connected.
Fig. 1 shows the schematic perspective view of connection structure between the girder of the hoisting crane 100 of the utility model embodiment and end wheel carrier.It should be noted that, the miscellaneous part of described hoisting crane 100, such as monkey (trolley) is well known to those skilled in the art, not shown in Figure 1.
Described hoisting crane 100 comprises girder 110 and end wheel carrier 130.Described girder 110 for setting up monkey, thus makes dolly can move along the length direction of girder 110.Described girder 110 is connected with described end wheel carrier 130, and therefore, when described end wheel carrier 130 runs along track (Fig. 1 is not shown), described girder 110 just can move along the length direction of described end wheel carrier 130 together with the dolly of erection on it.
In some embodiments, the two ends of described girder 110 are all connected with end wheel carrier, and the configuration of the end wheel carrier of the other end can be identical with described end wheel carrier 130, do not repeat them here.
Described girder 110 and described end wheel carrier 130 have a joint face separately on one end each other, and two joint faces contact with each other and connect.In some embodiments, as shown in Figure 1, two joint faces are connected by bolt 150.On the joint face of described end wheel carrier 130, be provided with the ledge structure 131 of this joint face outstanding.Described ledge structure 131 contacts with described girder 110, and bears the shearing force at least partially between described girder 110 and described end wheel carrier 130.Such as, as described in Figure 1, described girder 110 places on the upper surface of described ledge structure 131 in the bottom of the one end near described end wheel carrier 130, thus applies pressure to the upper surface of described ledge structure 131.
Fig. 2 show as shown in Figure 1 structure along the schematic cross-section in A-A direction.It should be noted that, in order to highlight the dimension scale of the parts shown in the dimension scale of the parts shown in described ledge structure 131, Fig. 2 and Fig. 1 and incomplete same.
As shown in Figure 2, the upper surface of described ledge structure 131 is vertical with gravity direction, namely keeps level.It should be noted that, mention in the utility model " on ", all refer to hoisting crane direction away from ground when assembling usage condition, so-called D score then depends on subaerial direction.Because the upper surface of described ledge structure 131 is vertical with gravity direction, the lower surface of described girder 110 near the end of described end wheel carrier 130 just can be placed on this upper surface reposefully, applies the pressure in direction consistent with gravity direction equably to it.In other embodiments, the upper surface of described ledge structure 131 can also have other to arrange, such as can be at an angle with horizontal direction, as long as the corresponding contact surface of described girder 110 can be coordinated, the upper surface of described ledge structure 131 stably can be fitted with this contact surface, ensure that described girder 110 can apply pressure to described ledge structure 131 fifty-fifty.
As shown in Figure 2, in some embodiments, described girder 110 is provided with connecting panel 111 (illustrating with point-like block diagram in Fig. 2) in the one end near described end wheel carrier 130.Described connecting panel 111 1 aspect is used for being connected by described bolt 150 with the joint face of described end wheel carrier 130, on the other hand for providing the contact surface of fitting with the upper surface of described ledge structure 131.That is, the lower surface of described connecting panel 111 is fitted with the upper surface of described ledge structure 131 and is contacted, and applies pressure to the upper surface of described end wheel carrier 131.In some embodiments, described connecting panel 111 is connected by the mode of welding with other parts of described girder 110, thus realize more firmly connecting, the upper surface be convenient to described ledge structure 131 applies pressure, the i.e. gravity at least partially of described girder 110.
In fig. 2, the width of the described ledge structure 131 illustrated is identical with the width of the lower surface of described connecting panel 111, thus make the lower surface of described connecting panel 111 be fitted on the upper surface of described ledge structure 131 completely, that is, the lower surface of described connecting panel 111 be all positioned at described ledge structure 131 upper surface on and contact with it.In other embodiments, the width of the upper surface of described ledge structure 131 also can be greater than or less than the width of the lower surface of described connecting panel 111.
In some embodiments, described end wheel carrier 130 also can be provided with perforate (not shown), for regulating described bolt 150 by this perforate.In some embodiments, described perforate is positioned on the another side relative with the joint face of described end wheel carrier 130, and position is corresponding with the position of described bolt 150.
The structure that the utility model provides, can provide more stable, safe connection.With reference to figure 2, owing to being provided with described ledge structure 131, being originally applied to the shearing force on bolt 150, being passed on described ledge structure 131 by described connecting panel 111 now.This shearing force creates a torque T to whole end wheel carrier 130
