Abstract
The utility model discloses a novel arm support for a blending material stacking machine; a main beam of the arm support is divided into a main beam front section, a main beam middle section and a main beam rear section, wherein the main beam rear section comprises a counterweight block, a hinged support and an oil cylinder support device, the hinged support and the oil cylinder support device are arranged at the lower part of the main beam rear section, the depth of the beam of the main beam rear section is higher than that of the main beam front section and the main beam middle section, meanwhile, a door-shaped upright pole, a draw bar and a steel wire digging rope device are arranged on the main beam rear section, one end of a handrail is connected with the door-shaped upright pole, and the other end of the handrail is connected with the main beam which is close to the counterweight block; one end of the steel wire digging rope device is connected with the door-shaped upright pole, and the other end of the steel wire digging rope device is connected with the main beam at the most front end of the arm support. The novel arm support for the blending material stacking machine has good rigidity and low process cost and can save materials.
Description
Technical field
The utility model belongs to bulk material heap taking equipment technical field, is specially a kind of novel jib that is applied to the mixed-windrowed locomotive in stock ground.
Background technology
Mixed-windrowed locomotive is a kind of ground such as large-scale bulk goods harbour, thermal powerplant, large-scale earthwork, steel mill, cement mill that are applied to, and carries out the heavy wares with homocline of storing up of materials such as coal, coke, ore, salt.Generally about 200 tons, wherein the weight of jib is more than 20 ton to the weight of mixed-windrowed locomotive complete machine, and framing member accounts for major part in entire equipment, and framing member is generally steel and is welded, and the visible material cost occupies very big proportion in the mixed-windrowed locomotive total cost.
The length of the jib of mixed-windrowed locomotive generally is 20 ~ 40 meters, and in use jib should satisfy rigidity requirement, needs version reasonable in design for this reason.On the other hand, jib is in the top of whole mixing machine, if the weight of jib can alleviate, then other component weight of mixing windrow also can alleviate.The jib structure of traditional design is divided into two sections, and the height that jib is two sections is identical, passes through Bolt Connection between the two-piece boom.Pull rod device is arranged on jib, play the effect that jib is strengthened.The Heavy Weight of this jib, the material that expends is many.Since the jib Heavy Weight, the limited length that jib allows, and the length of its permission generally is no more than 30 meters.When if the angle of jib pitching is bigger, the hopper that pull bar and trailer may occur is interfered, and influences the use of machine.
The utility model content
The technical matters that the utility model solved is to provide a kind of mixed-windrowed locomotive novel jib, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solved adopts following technical scheme to realize:
The novel jib of a kind of mixed-windrowed locomotive, jib girder are divided into three sections: girder leading portion, girder stage casing and girder back segment.Wherein, the girder back segment comprises clump weight, hinged-support and oil cylinder bracing or strutting arrangement, and hinged-support is positioned at pars infrasegmentalis behind the girder and links to each other with A font gate seat on the stocker in the bottom, is the fulcrum of whole jib, and the weight major part of jib is born by hinged-support; The oil cylinder bracing or strutting arrangement of pars infrasegmentalis connects the pitching that the pitching oil cylinder is realized jib behind the girder, thereby bigger power is also born in arm support oil cylinder support place.
These two strong point installation sites are nearer, so in order to guarantee girder intensity here, the deck-molding of the girder of this section designs than higher.A type vertical rod is installed on this section girder simultaneously; One pull bar and steel wire tow line device also are set, and railing one end links to each other with the vertical rod of door type, and an other end links to each other with girder near weight box; Steel wire tow line device one end links to each other with the vertical rod of door type, and an other end and jib girder foremost link to each other.
In the utility model, the monolithic devices vertical rod that the vertical rod of door type can be formed in one also can be used two middle compound type vertical rods of forming through the pull bar ways of connecting of vertical hold-down arms.
In the utility model, the girder stage casing of jib girder and girder leading portion mainly play the effect of back-up belt machine, and this two sections stressed little is so the girder height of jib can be littler than girder back segment height value in the time of design-calculated.
Beneficial effect:The utility model is satisfying under the prerequisite of in-use performance, has alleviated the weight of jib.The counterweight that the jib of new structure form needs is in light weight, because the weight saving of jib, other the weight of parts of complete machine can correspondingly alleviate, but saving in material, and it is low to cut down finished cost, and improves it and makes economy.And the length of the jib of new structure form permission jib can be longer, and the pull bar of jib can partly not interfered with the trailer hopper in the jib pitching.
Description of drawings
Fig. 1 is the scheme drawing of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
In the preferred embodiment referring to the novel jib of a kind of mixed-windrowed locomotive of Fig. 1, the jib girder is divided into 6 three sections of girder leading portion 9, girder stage casing 8 and girder back segments, and girder back segment 6 is highly higher than girder leading portion 9 and girder stage casing 8.
Main beam rear end 6 bottoms at present embodiment are provided with two bearings, and the hinged-support 11 that is respectively bottom connection A font gate seat is connected the oil cylinder bracing or strutting arrangement 10 of pitching oil cylinder with the bottom; A type bearing is arranged at main beam rear end 6 tops, and this type bearing is made up of left hold-down arm 3, right hold-down arm 5 and lateral connecting rod 4, and right hold-down arm 5 side bypass are crossed the delivery position place that steel wire tow line device 7 is connected to girder leading portion 9 and girder stage casing 8; Left side hold-down arm 3 side bypass are crossed digonal link 2 and are connected to main beam rear end 6, simultaneously, also are provided with a clump weight 1 at the end of main beam rear end 6.
More than show and described the advantage of groundwork, principal character and the utility model of the utility model.The technical personnel of the industry should be understood; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model protection defined by the appended claims and their equivalents defined
