Abstract
The utility model provides an adjustable lifting device, and mainly solves the problems that the distance between a spray pipe and a chassis of conventional road maintenance equipment is fixed, without adjustment, so that normal operation on a non-planar pavement is not carried out, and a conventional lifting device is fixed, without adjustment, so that the conventional lifting device cannot be suitable for various vehicle models of different chassis heights. The adjustable lifting device is characterized in that a plurality of connection holes are formed in a lifting bar, meanwhile, a positioning hole is formed in a pull rod, the lifting bar is connected with the pull rod through a pin shaft, so that the original fixed connection manner is changed into a multi-stage adjustable connection manner, the capability of the road maintenance equipment adapting to different pavement to operate is improved greatly, and the adjustable lifting device adopting the connection manner is low in cost, has a simple structure, and is high in reliability.
Description
Technical field
The utility model provides a kind of adjustable lifting appliance, is mainly used in controlling the height of spray line.
Background technology
At present, highway maintenance equipment is when carrying out operation, especially truck spreader is when carrying out operation, may run into the situation of the on-plane surface operations such as road surface inclination, and distance between spray line and the chassis of existing highway maintenance equipment is fixed and cannot regulate, therefore, under above-mentioned condition of work, possibly cannot normally work, thereby affect programming, when serious, also may cause the damage of spray line.
Meanwhile, existing highway is maintained equipment due to vehicle difference, and chassis height is also not quite similar, and the lifting appliance of spray line is fixing nonadjustable form, therefore for different vehicles, need process the lifting appliance of multiple different model, has greatly improved cost.
Summary of the invention
The utility model provides a kind of adjustable lifting appliance, the distance mainly having solved between existing highway maintenance of equipment spray line and chassis is fixed, cannot regulate, thereby cause on on-plane surface road surface cannot normal operation problem and existing lifting appliance fixing non-adjustable, cannot be applicable to the problem of the vehicle of multiple different chassis heights.
Concrete technical solution of the present utility model is as follows:
This is adjustable, and lifting appliance comprises cylinder, and the cylinder rod of cylinder is fixedly connected with pull bar, and pull bar outside is set with lifting arm, and pull bar overlaps with lifting arm central axis; On lifting arm, be provided with at least two each and every one for regulating the connecting hole of collapsing length, on pull bar, be provided with one with the suitable locating hole of connecting hole, between lifting arm and pull bar, by bearing pin, pass locating hole and connecting hole is located by connecting, spray line is fixedly connected with lifting arm.
Above-mentioned connecting hole is three to seven.
Above-mentioned lifting arm outside is set with sleeve pipe, and sleeve pipe one end is fixedly connected with cylinder baffle, and sleeve pipe overlaps with pull bar central axis; Described sleeve pipe other end port should make bearing pin carry out when lifting arm is connected with pull bar carrying out at sleeve pipe outward.
The utility model has the advantage of:
This is adjustable lifting appliance is owing to being provided with multistage connecting hole on lifting arm, on pull bar, be provided with again locating hole simultaneously, and connect by bearing pin, make the original mode that is fixedly connected with become multistage adjustable connected mode, greatly improved the ability that highway maintenance equipment adapts to the operation of different road surfaces, and which cost is low, simple in structure, reliability is high.
This is adjustable, and lifting appliance can also adapt to the vehicle of various different chassis heights, uses very easy.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Accompanying drawing is detailed as follows:
1-cylinder; 2-cylinder rod; 3-pull bar; 4-lifting arm; 5-connecting hole; 6-locating hole; 7-bearing pin; 8-spray line; 9-sleeve pipe.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, as shown in Figure 1:
This is adjustable, and lifting appliance comprises cylinder, and the cylinder rod of cylinder is fixedly connected with pull bar, and pull bar outside is set with lifting arm, and pull bar overlaps with lifting arm central axis; On lifting arm, be provided with at least two each and every one for regulating the connecting hole of collapsing length, the quantity of connecting hole determines according to real work situation, general connecting hole suggestion is set to three to seven; On pull bar, be provided with one with the suitable locating hole of connecting hole, between lifting arm and pull bar, by bearing pin, pass locating hole and connecting hole is located by connecting, spray line is fixedly connected with lifting arm.
Lifting arm outside is set with sleeve pipe, and sleeve pipe, for the protection of pull bar and lifting arm, avoids it directly to cause serious wear, sleeve pipe one end to be fixedly connected with cylinder baffle with extraneous contact, and sleeve pipe overlaps with pull bar central axis; Sleeve pipe other end port should make bearing pin carry out when lifting arm is connected with pull bar carrying out at sleeve pipe outward, and this set-up mode has been avoided also need on sleeve pipe, punching, thus the problem that causes precision, cost to improve.
During use: first set bearing pin position according to the chassis of differing heights, control the lifting of lifting arm during work by cylinder.
