Abstract
The utility model discloses an uncoupling rigging of a crane. The utility model comprises a weight-bearing movable pin which is arranged on the top of a cage type bearing structure to support a lifting part (A) according to the requirement of the variable of lifting height; the bottom of a lifting part (B) whose top is hung on the crane is provided with a left-right symmetric connection-rod type gripping hook. The utility model has the advantages that no horizontal component force is generated when a load is unhooked in an impending situation so the load can be kept stable; the crane can be protected from being damaged by the impact of counter force; the functions of automatic hooking and unhooking are provided; the utility model can be applied to the operation occasions that the load needs to be lifted up and release to impact a force bearing object, particularly a matching equipment for the dynamic test of the bearing capacity of the pile foundation in the foundation detection technology of construction.
Description
The utility model relates to the supporting load of weight-lifting equipment and tangles part or device (B66C).
Along with the continuous development of engineering up-to-date technology, the running condition of weight-lifting equipment load hook is also corresponding to be changed to some extent.For example, lift by crane a load,, impact the load thing on the relevant position, below its unsettled release.This operation, the olecranon hook that utilizes general weight-lifting equipment to be equipped with, more shallow as hook, case accident often meets accident, darker as hook, then be difficult to load is discharged, discharge as forcing, will produce very big horizontal component of force and counter-force and impact, unstability when load is fallen, and easy damaged weight-lifting equipment.For addressing this problem, the method of prior art is: design static cage type load larrying member, place on ground or the bearing table, the top of cage type load larrying member is provided with to hold to mount and puts, other establishes a load and tangles part, with hoisting crane olecranon hook load is tangled part and winch to certain altitude, hang on to hold to mount and put, force again load is discharged.This method because load tangles the form that the olecranon hook is not broken away from the hook design of part, still has the generation of horizontal component of force.In addition, owing to can not give to manipulate and bring inconvenience automatically with load hook and unhook.
The purpose of this utility model is to design a kind of lifting trip mechanism, and its anhydrous power of dividing equally when the unsettled unhook of load is produced, and has the function of automatic hitch and unhook, and makes the do not broken off relations damage of counter-force of weight-lifting equipment.
For achieving the above object, the utility model proposes such design plan: establish static cage type load larrying member, place on ground or the bearing table, this structural top is established a supporting removable pin and a key seat; The cage heart is established a lifting subassembly, and this lifting subassembly comprises lifting member first and lifting member second, and the lifting member first is hung on the removable pin, and lifting member second is hung on the weight-lifting equipment, and symmetrical two link-type clip hooks are established in the bottom.Shake out removable pin, lifting subassembly descends with hoisting hook, and clip hook and load bump against the back automatic hitch; Removable pin automatically resets; After lifting subassembly was promoted to desired height, the first lifting member hung on the removable pin; The weight-lifting equipment unloading is also loosened lifting member second, and the link-type clip hook is implemented automatically-unhooked action, discharges load.
Embodiment is described in detail as follows with reference to accompanying drawing:
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Accompanying drawing 2 is that the A of accompanying drawing 1 is to enlarged diagram.
Static cage type load larrying member (1), a supporting removable pin (2) and a key seat (23) (24) established at its top, cage heart place establishes a lifting subassembly, this lifting subassembly comprises: the lifting member first--lattice lifting member (3) is long annular, be provided with a plurality of arc lattice shelves (17), with the height of control load lifting; Lifting member second--lattice lifting member (7) is not established symmetrical two steel ropes, and each is connected its upper end with last moved cross beam (6), and each is connected steel rope peripheral hardware orienting sleeve (16) lower end with following moved cross beam (10); If a balanced body (9), its upper end is established one and is hung pin (8), is hung on the bottom of lattice lifting member (3), and its center is a through hole, makes the criss-cross pivot bush unit with following moved cross beam (10); Establish two link-type clip hooks of symmetry about following moved cross beam (10), its composition comprises: connecting rod (12) upper end and (a 11) running-fit of going up that is located at down moved cross beam (10) two ends, lower shaft (14) running-fit that lower end and clip hook (13) upper end is set, the last arc portion of two clip hooks (13) respectively establishes a through hole, with hook axle (15) running-fit that is located at balanced body (9) lower end.Last moved cross beam (6) also is provided with beam pin (5) and suspension member (4), and whole lifting subassembly is suspended on the weight-lifting equipment.
Key seat (23) (24) at the above is provided with semicircle open form pin-and-hole, cooperates with removable pin (2), and key seat is also established an axis hole on (23), and fixing little axle (22) passes the set through hole of removable pin (2) one ends and this axis hole running-fit; Removable pin is also established a screw, and screw axial line and removable pin axle center line form angle α, and other establishes a turning handle (20), and its end that is shaped on screw thread cooperates with this screw; Also be provided with one at the turning handle other end and hold the soft rope of power (20), force in soft rope, then shake out removable pin, unclamp soft rope, then removable pin resets.Between removable pin (2) and key seat (23), establish a retracing spring (25), help removable pin to reset.
The anhydrous power of dividing equally produced when the utility model can make the unsettled unhook of load thing in operation; the load thing falls steadily, accurate positioning, and the damage that can protect weight-lifting equipment not impacted by counter-force; therefore the function that also has automatic hitch and unhook is manipulated very convenient.
The utility model is applicable in the site operation process, needs load lifting and release, and the operation occasion of impacting the load thing is specially adapted in the building operation ground detection technique corollary apparatus of bearing capacity of pile foundation dynamic test.
