Description
Technical field
The utility model relates to material transfer equipment, relates in particular to the waggon that is used for the anti-overload suspender of coming off automatically of telescopic belt waggon and has the anti-overload suspender that comes off automatically.
Background technology
As a kind of open type material transfer equipment, the telescopic belt waggon is because the material scope of its conveying is wide, can carry three grades of concrete material even more senior concrete material, therefore for improving construction quality, production efficiency and manufacturing schedule, in many heavy construction projects, all adopt this equipment, particularly particularly outstanding in the middle of the Dam Construction of power station.For the material that reduces blanking place of telescopic belt waggon disperses, generally all be lifted with the long tail pipe of 3～5m at its jib blanking end, under the effect of this tail pipe, can realize the concentrated accumulation of material.But, excessive or fixed point convey materials is piled up too high when tail pipe is stopped up when the convey materials particle, continue feeding if fail in time to find, then can cause a large amount of materials to concentrate is deposited on tail pipe even the jib, can cause boom system because of the excessive gross distortion of load like this, even serious construction safety accident take place in the jib that fractures.
The patent No. is that the utility model patent of ZL200820059972.8 discloses a kind of automatic dropping device that a machine hangs stake that is used for, and this device generally is used for weight-lifting equipment.Earlier weight is winched to assigned address during use, by the seizing wire of operating personal tractive automatic dropping device, movable iron bolt is drawn back again, thereby make weight break away from automatic dropping device, finish the operation of breaking off relations with automatic dropping device.This shows, the external force that needs this device realizes separating of weight and suspension hook, inconvenient operation, simultaneously it and be unwell to the tail pipe of lifting telescopic belt waggon, because when the tail pipe of finding the telescopic belt waggon stops up, the tail pipe that hangs is more and more heavier, wants this moment to realize that by pullling seizing wire the disengaging of tail pipe is very difficult.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, but automatic release weight when a kind of the overload is provided, reliability height, simple in structure, the anti-overload suspender that comes off automatically being convenient to make, and tail pipe stops up and can break away from and remove the waggon with the anti-overload suspender that comes off automatically that the mass transport circuit stops up voluntarily after overweight.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of anti-overload suspender that comes off automatically comprises the U-shaped button with a pair of pin-and-hole, all is equiped with a latch with axial elastic force in each pin-and-hole of described U-shaped button, and two latches compress butt joint mutually, and are provided with the separation targeting port in joint.
Described separation targeting port is made of two set chamfering or roundings in latch butt end.
Described latch comprises sleeve, bearing pin and compression spring, described sleeve one end sealing, other end opening, the open end of sleeve dock with pin-and-hole and be fixed in U-shaped to be buckled, described bearing pin and compression spring are installed in the sleeve, and compression spring is supported between sleeve closed end and the bearing pin.
Described sleeve comprises hollow sleeve and spiro cap, and described hollow sleeve one end and U-shaped button join, and the other end is provided with screw thread, described spiro cap one end sealing, and the other end is threaded with hollow sleeve.
A kind of waggon with the anti-overload suspender that comes off automatically comprises and carries jib and tail pipe, be equiped with on the described conveying jib as claim in each described anti-overload suspender that comes off automatically, tail pipe is lifted on the described anti-overload suspender that comes off automatically.
Be connected with safety rope between described conveying jib and the tail pipe.
Compared with prior art, advantage of the present utility model is: the anti-overload suspender that comes off automatically of the present utility model is by a pair of latch carrying weight that compresses butt joint mutually, joint at two latches is provided with the separation targeting port simultaneously, when the weight weight of being hung exceeds the suspender load-carrying capacity, suspender on the weight pushes two latches in separating the targeting port place, promote latch to overcome self axial elastic force and bounce back, thereby make suspender break away from the suspender constraint, finish automatic release to the overload weight, do not need manual operation in the process from overloading to breaking away from, finish fully automatically, the reliability height, and this anti-overload hanger structure that comes off automatically is simple, is convenient to make.Latch is made of sleeve, bearing pin and compression spring, its middle sleeve is formed by being threaded by hollow sleeve and spiro cap, the rotary nut cover can regulating sleeve length, thereby change the predetermincd tension of compression spring, therefore can make the anti-overload suspender comformability that comes off automatically stronger according to the predetermincd tension of carrying operating mode to come regulating spring.In the waggon with the anti-overload suspender that comes off automatically of the present utility model, after stopping up, tail pipe can increase along with its weight of increase of material, when exceeding the suspender load-carrying capacity, suspender automatic release tail pipe, make tail pipe break away from the mass transport circuit, material is skipped tail pipe and is directly sent, thereby guarantees the unobstructed of mass transport circuit, avoids long-time obstruction of mass transport circuit and the initiation other accident; But carry attachment security rope between jib and the tail pipe, after tail pipe and suspender disengaging, under the pining down of safety rope, can not injure peripheral equipment and staff, safety improves.
