Abstract
The utility model discloses a hydraulic loading and unloading mechanism for a pit barring carrier. The hydraulic loading and unloading mechanism comprises a vehicle frame, a hydraulic oil cylinder and a rocker arm; the hydraulic oil cylinder is hinged with a hydraulic oil cylinder support fixed on the vehicle frame; a piston rod of the hydraulic oil cylinder is hinged with one end of the rocker arm; the other end of the rocker arm is fixedly connected with one end of a lifting arm; the connection part of the other end of the rocker arm and one end of the lifting arm is hinged with a rocker arm support which is fixed on the vehicle frame; and the other end of the lifting arm is hinged with a hoisting device. The hydraulic loading and unloading mechanism has the characteristics of compact structure, strong hoisting capacity, convenience in operation and using and the like.
Description
Technical field
The utility model relates to a kind of hydraulic loading-unloading machinery, especially a kind of vehicle-mounted hydraulic loading-unloading machinery.
Background technology
Under mine, using a large amount of hydraulic supports,, often need carry out the carrying and installation of hydraulic support,, can't adopt lifting appliance to load and unload because the tunnel is narrow below the mine along with the progressively expansion of coal mine excavation scope.
The utility model content
Characteristics such as the technical matters that the utility model will solve provides a kind of hydraulic loading-unloading mechanism of pit barring transport trolley, and it has compact conformation, and crane capacity is strong, and is easy for operation.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: it comprises vehicle frame, and it also comprises hydraulic ram in addition; Hydraulic ram is twisted together with the hydraulic ram bearing that is fixed on the vehicle frame; It also comprises rocking arm, and an end of the piston rod of hydraulic ram and rocking arm is twisted together, and the other end of rocking arm is captiveed joint with an end of lift arm; Its junction is twisted together with the rocker arm support that is fixed on the vehicle frame, and the other end and the lifting appliance of lift arm are twisted together.
The utility model further improves and is:
Said lifting appliance comprise chain sling and with chain sling bonded assembly suspension hook;
Said lifting appliance can also be the suspension rod of band suspension hook.
Adopt the beneficial effect that technique scheme produced to be: adopt hydraulic ram as takeoff output, moment is big, and crane capacity is strong, and it also has compact conformation in addition, and is easy to operate, reliable operation, advantage such as fault rate is low.
Description of drawings
Fig. 1 is the structural representation of the utility model;
In the accompanying drawings: 1, vehicle frame; 2, rocker arm support; 3, lift arm; 4, rocking arm; 5, suspension hook; 6, hydraulic ram; 8, hydraulic ram bearing; 9, chain sling.
The specific embodiment
Can be known that by embodiment shown in Figure 1 it comprises vehicle frame 1, it also comprises hydraulic ram 6 in addition; Hydraulic ram 6 is twisted together with the hydraulic ram bearing 8 that is fixed on the vehicle frame 1; It also comprises Rocker arm 4, and an end of the piston rod of hydraulic ram 6 and Rocker arm 4 is twisted together, and the other end of Rocker arm 4 is captiveed joint with an end of lift arm 3; Its junction is twisted together with the rocker arm support 2 that is fixed on the vehicle frame 1, and the other end and the lifting appliance of lift arm 3 are twisted together; Lifting appliance comprise chain sling 9 and with chain sling 9 connecting shackles 5.
Principle of work:
The operation multiway valve, hydraulic ram big chamber oil-feed, piston rod is protruding, and promotion rocking arm and lift arm rotate counterclockwise simultaneously suspension hook are upwards promoted together with pit barring; The operation multiway valve makes the oil-feed of hydraulic ram loculus, and the piston rod withdrawal clockwise rotates rocking arm and lift arm simultaneously suspension hook is descended, and pit barring is put on the ground.
