Abstract
The present invention relates to a kind of dust absorption nozzle and promote self-locking device.Mainly solve after existing all kinds of sweeping machine dust absorption nozzle assembly relies on hydraulic jack and steel cable to promote and can not lock completely, in sweeping machine driving process, dust absorption nozzle slowly falls to affecting the normal problem travelled.The present invention is combined to form by lift cylinder, cylinder support, three hole connecting levers, connecting lever bearing, steel cable, length adjustment bar and bearing pin.Described three hole connecting levers are placed between lift cylinder and steel cable, and by hinge, described three hole connecting levers are hinged to the fixing centre of gyration by bearing pin and connecting lever bearing hole, and described connecting lever bearing upper end offers one towards the arc groove of three hole connecting levers lifting direction of rotation.Pull three hole connecting levers to upper rotary at lift cylinder, make steel cable connect bearing pin and enter arc groove and after walking around the connecting lever bearing centre of gyration, dust absorption nozzle relies on deadweight to form moment and self-locking.
Description
Art
The present invention relates to a kind of dust absorption nozzle for all kinds of sweeping machine and promote self-locking device, sweeping machine is the special-purpose vehicle for environmental sanitation cleaning, operation of keeping a public place clean.
Background technology
Dust absorption nozzle carries out the equipment that rubbish receives lifting in all kinds of sweeping machine cleaning work process.During sweeping machine cleaning work, this dust absorption nozzle drops to cleaning road surface and carries out rubbish and receive, and cleaning work terminates, and dust absorption nozzle must promote a height sweeping machine and could normally travel.The common feature of existing all kinds of sweeping machine is, dust absorption nozzle can not be locked after only relying on hydraulic jack and steel cable to promote completely, in sweeping machine driving process due to vibrations, the reason such as to leak in hydraulic system and cause dust absorption nozzle slowly to fall, affect sweeping machine normally to travel, also have and adopt special hydraulic locking, but along with the increase of sweeping machine service time, when hydraulic system starts interior leakage occurs, dust absorption nozzle whereabouts phenomenon also occurs thereupon.Therefore, sweeping machine needs a kind of dust absorption nozzle completely reliably to promote self-locking device.
Summary of the invention
In order to overcome shortcoming and the weak point of background technology, the invention provides a kind of dust absorption nozzle and promoting self-locking device, solve after existing sweeping machine dust absorption nozzle promotes and can not completely reliably lock, generation falls to affecting the problem that sweeping machine normally travels.
Technical scheme of the present invention is: a kind of dust absorption nozzle promotes self-locking device, comprise cylinder support, lift cylinder, connecting lever bearing, three hole connecting levers, steel cable, length adjustment bar and bearing pin one, bearing pin two, bearing pin three, bearing pin four and bearing pin five, lift cylinder tail end is connected with cylinder support by bearing pin one, plunger end is connected by the hole one of bearing pin two with three hole connecting levers, steel cable one end is connected by the hole three of bearing pin four with three hole connecting levers, the other end is connected with length adjustment bar, dust absorption nozzle bearing is connected with length adjustment bar by bearing pin five, the Kong Si of connecting lever bearing is connected by the hole two of bearing pin three with three hole connecting levers, it is characterized in that: described three hole connecting levers are placed between lift cylinder and steel cable, passing hole two fixedly becomes rotating central hole with the Kong Si of connecting lever bearing with bearing pin three, three hole connecting levers produce gyration and form dust absorption nozzle lifting and the slew gear declined under the promotion of lift cylinder, when dust absorption nozzle rises, the bearing pin four be connected with the hole three of three hole connecting levers enters the arc groove of connecting lever bearing, stop when arriving arc groove tail end, now dust absorption nozzle line of gravity is positioned at the left side of bearing pin three vertical center line, self-locking device is formed by the effect of dust absorption nozzle gravity torque.
The pitch of holes in the Kong Yiyu hole two of described three hole connecting levers is less than the pitch of holes in Kong Eryu hole three, and work hole when one and Kong Sanjun with hole two central point for the centre of gyration.
Arc groove center line Yi Kong tetra-center, described connecting lever bearing upper end is the centre of gyration, and the radius of gyration equals the pitch of holes in the Kong Eryu hole three of three hole connecting levers.
Arc groove fluting direction, described connecting lever bearing upper end is the direction of rotation promoted towards three hole connecting levers, and described arc groove tail end semicircle center is placed in the rear side of hole four vertical center line, and arc groove width is greater than three hole connecting levers are connected bearing pin four diameter with steel cable.
When described three connecting lever Kong tri-centers, hole arrive arc groove tail end semicircle center, connecting lever bearing upper end, the center in hole one is placed in the upside of the Kong Eryu cylinder support hole line of centres.
The present invention has following beneficial effect: this dust absorption nozzle promotes self-locking device and pulls three hole connecting levers to upper rotary at lift cylinder, steel cable connecting hole center is made to enter arc groove and after walking around the connecting lever bearing centre of gyration, even if lift cylinder decompression, dust absorption nozzle relies on self-weight self-locking, can not produce decline and drop and affect sweeping machine and normally travel.Only need when needs decline dust absorption nozzle cleaning works oil cylinder pushing three hole connecting lever to be rotated down, therefore reliable lock, be applicable to the lifting locking of all kinds of sweeping machine dust absorption nozzle.
