Detailed description of the invention
The embodiment that can connect the hoisting crane drop in beam changing interchangeable drop in beam fast of the present invention, just like shown in Fig. 1 ~ Fig. 5, is described in detail to the embodiment of the present invention below in conjunction with accompanying drawing:
Fixing drop in beam 1 comprises the first connecting panel 11 set gradually from top to bottom, second connecting panel 12 and the 3rd connecting panel 13, the lock 21 of quick manual blocking device 2 is pierced into fixing drop in beam 1 from lower end, when lock head passes the second connecting panel 12, adopt and be threaded onto lower rotation on lock 28 successively, upper rotation 25, the axial limiting mechanism that packing ring 24 and lock nut 23 form is by lock axial limiting and rotation is assemblied on drop in beam, concrete mode is set with lower rotation 28 successively, upper rotation 25, packing ring 24 and lock nut 23, screw in lock nut 23, force rotation 25 and lock to be connected by key 29 and with lower rotation 28 conical surface press-fit, and make lower rotation width be pressed between the shaft shoulder of lock and lower rotation width by the second connecting panel 12, now adopting position-limitting pin 210 to penetrate the pin-and-hole that lock and lock nut 23 are disposed radially, fixedly to make it not turn round on lock nut loosening, the shaft shoulder place that lock 21 stretches out the first connecting panel 11 is provided with locating plate 22, lock radially offers the hole for wearing horizontal pin 212, lock end is connected with taper locking block 213, taper locking block 213 for bottom surface be oval pyramidal structure.As shown in Figure 3, in the manner described above quick manual blocking device is rotatably installed on four limits of fixing drop in beam.Relevant position on interchangeable drop in beam I 3 is as shown in Figure 4 and Figure 5 offered the taper locking block 213 for installing quick manual blocking device and is made it have the waist shaped hole 31 separating lock-bit and locking position when rotated, the major diameter that minor face aperture is less than the major diameter of taper locking block 213, the lateral opening footpath of length of waist shaped hole 31 is greater than taper locking block 213 of waist shaped hole 31, the minor face aperture of waist shaped hole 31 is greater than the minor axis diameter of taper locking block 213.
In the present invention, the embodiment of hoisting crane is just like shown in Fig. 2 ~ Fig. 5, is described in detail to the embodiment of the present invention below in conjunction with accompanying drawing:
First the jack up unit 8 of fixing drop in beam by steel rope and assembly pulley composition is linked into an integrated entity with the above-mentioned fixing drop in beam 1 being equipped with quick manual blocking device 2, jack up unit 8 can realize the lifting of fixing drop in beam 1, be provided with below interchangeable drop in beam I and hang thing device 6 for what lift material, when needing according to the difference of lifting object the drop in beam changing different size specification, need fixing drop in beam 1 to be connected fast with corresponding interchangeable drop in beam, be illustrated in figure 2 in this hoisting crane and fix drop in beam 1 and carry out being connected the using state figure used with interchangeable drop in beam I 3.The taper locking block 213 of the lock end of the quick manual blocking device be assemblied on fixing drop in beam 1 guiding is pierced in the corresponding waist shaped hole 31 that interchangeable drop in beam I 3 is offered, by lock 21 90-degree rotation, make the minor face aperture of waist shaped hole 31 and the longer axis parallel of taper locking block 213 bottom surface ellipse, now because the aperture of the minor face of waist shaped hole 31 is less than the major diameter of taper locking block 213, block is formed to taper locking block 213, thus make taper locking block 213 locking can not depart from interchangeable drop in beam I 3, locating dowel pin 211 is adopted to penetrate the corresponding knock hole that the first connecting panel 11 of tapped bore and the fixing drop in beam 1 that locating plate 22 is offered is offered, both positions fixing, horizontal pin 212 is penetrated in lock 21, between the horizontal pin 212 that locating plate 22 is clamped on and the lock shaft shoulder, prevent lock 21 from turning round in motion process and cause taper locking block 213 to be deviate from from the corresponding waist shaped hole 31 of interchangeable drop in beam I 3.
During the interchangeable drop in beam needing replacing specification different when lifting object structural change, only need unclamp horizontal pin 212 and locating dowel pin 211, by lock 21 90-degree rotation, make the minor axis of taper locking block 213 parallel with the long limit of waist shaped hole 31, now because the lateral opening footpath of length of waist shaped hole 31 is greater than the diameter of taper locking block 213 major axis, waist shaped hole 31 minor face aperture is greater than the minor axis diameter of taper locking block 213, therefore taper locking block 213 is in the solution lock-bit freeing in and out waist shaped hole 31, taper locking block 213 can be deviate from from waist shaped hole 31, make fixing drop in beam 1 and the disengagement of interchangeable drop in beam I.
Fig. 6 ~ Figure 7 shows that the embodiment of the present invention two and the structural representation implementing three, different unlike the size of interchangeable drop in beam II 4 to be locked and interchangeable drop in beam III 5 from above-described embodiment, adopt the drop in beam in the present invention the interchangeable drop in beam of fixing drop in beam with other required size specification can be connected rapidly.
Axial limiting mechanism in above-described embodiment can also adopt bearing, realizes the axial limiting of lock and assembles with the rotation of link span.
Adopt in the above-described embodiments locating dowel pin is threaded onto tapped bore on locating plate and link span the first connecting panel on corresponding knock hole be in locking position to maintain lock, locating plate can not also be adopted in other embodiments, and on lock, radially offer through hole, and the knock hole adopting L shape bearing pin to be threaded onto relevant position on the through hole of the radial direction that lock is offered and the first connecting panel realizes.
Locating dowel pin is threaded fixing with adopting between locating plate and the first connecting panel in the above-described embodiments, pin can also be adopted to lock in other embodiments fixing.
The bottom surface of taper locking block is oval in the above-described embodiments, and its bottom surface can also be oblong in other embodiments.
