Technical field
The utility model relates to a kind of drag-line durable test stand, and is particularly a kind of for the eccentric mechanism on the drag-line durable test stand.
Background technology
Be used at present the eccentric mechanism on the drag-line durable test stand, usually done reciprocating linear motion by electrical control air cylinder driven drag-line, when needs are tested the drag-line of different model, need to reset different parameters, in order to the movement travel of control cylinder, and then to reach test objective, operation is trouble, efficient is lower, and whole electrical control equipment cost is higher, has increased undoubtedly experimentation cost.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, provides a kind of for the eccentric mechanism on the drag-line durable test stand, and simple in structure, manufacturing cost is lower, and is easy to operate.
For achieving the above object, the technical solution of the utility model has provided a kind of for the eccentric mechanism on the drag-line durable test stand, comprise bracing frame, the round turntable that rotates and be connected by the first rotating shaft with described bracing frame, be opened in a plurality of mounting holes on the described rotating disk, one end has the driving stem of Plug Division, the slide block that is fixedly connected with the other end of described driving stem, be arranged at the guide rail on the described bracing frame, the drag-line erecting frame that is fixedly connected with described slide block, described Plug Division can be inserted in the described mounting hole, a plurality of described mounting holes all depart from described the first rotating shaft, described slide block is arranged on the described guide rail slidably, and a plurality of described mounting holes are along the radial distribution of described rotating disk.
As preferably, be provided with approach switch on the described slide block, be provided with guide frame on the described bracing frame, offer gathering sill on the described guide frame, described approach switch is arranged in the described gathering sill slidably.
As preferably, the glide direction of described slide block parallels with the length direction of described gathering sill.
As preferably, the direction of axis line of the glide direction of described slide block and described the first rotating shaft is perpendicular.
As preferably, also comprise the driving mechanism that drives described dial rotation.
Advantage of the present utility model and beneficial effect are: by upwards offer the mounting hole of a plurality of Plug Divisions for driving stem is installed in the footpath of round turntable, when needs are tested the drag-line of different model, only the Plug Division need to be inserted in the corresponding mounting hole and get final product, operate more convenient, and device structure is simple, and manufacturing cost is lower.
Description of drawings
Fig. 1 is the utility model synoptic diagram.
Among the figure: 1, bracing frame; 2, rotating disk; 3, the first rotating shaft; 4, mounting hole; 5, Plug Division; 6, driving stem; 7, slide block; 8, guide rail; 9, drag-line erecting frame; 10, approach switch; 11, guide frame; 12, gathering sill.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of for the eccentric mechanism on the drag-line durable test stand, comprise bracing frame 1, the round turntable 2 that rotates and be connected by the first rotating shaft 3 with described bracing frame 1, be opened in a plurality of mounting holes 4 on the described rotating disk 2, one end has the driving stem 6 of Plug Division 5, the slide block 7 that is fixedly connected with the other end of described driving stem 6, be arranged at the guide rail 8 on the described bracing frame 1, the drag-line erecting frame 9 that is fixedly connected with described slide block 7, described Plug Division 5 can be inserted in the described mounting hole 4, a plurality of described mounting holes 4 all depart from described the first rotating shaft 3, described slide block 7 is arranged on the described guide rail 8 slidably, and a plurality of described mounting holes 4 are along the radial distribution of described rotating disk 2.
As shown in Figure 1, be provided with approach switch 10 on the described slide block 7, be provided with guide frame 11 on the described bracing frame 1, offer gathering sill 12 on the described guide frame 11, described approach switch 10 is arranged in the described gathering sill 12 slidably.
As shown in Figure 1, the glide direction of described slide block 7 parallels with the length direction of described gathering sill 12.
As shown in Figure 1, the direction of axis line of the glide direction of described slide block 7 and described the first rotating shaft 3 is perpendicular.
Without diagram, the eccentric mechanism that is used on the drag-line durable test stand also comprises the driving mechanism that rotates be used to driving described rotating disk 2, and described driving mechanism comprises motor and reductor.
Motion process: drive rotating disk 2 by motor and reductor and rotate around the first rotating shaft 3, and the center of rotation of the first rotating shaft 3 is departed from the Plug Division 5 on the driving stem 6, be equivalent to eccentric wheel, so that driving stem 6 does reciprocating linear motion, do reciprocating linear motion along guide rail 8 by driving stem 6 band movable sliders 7, and then drive drag-line erecting frame 9 does reciprocating linear motion, namely spurring drag-line does reciprocating linear motion, thereby reach test objective, when needs are tested the drag-line of different model, corresponding mounting hole 4 interior getting final product are inserted in Plug Division 5, operate more convenient.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
