Abstract
A mine mechanical face digger bucket-opening mechanism relates to mine diggers, and solves the problems that the prior art has complicated structure and inconvenient motor no-load vehicle test. The bucket-opening mechanism comprises a motor, a reel, a support, a small gear, a flange and a bearing; the motor is connected with the support through the flange; the small gear is fixed onto a spline shaft of the motor; the bearing is arranged between the spline shaft and a supporting part; the reel is fixed onto the support; and the small gear driven by the motor meshes with a large gear ring of the reel to drive the reel to rotate. The mine mechanical face digger bucket-opening mechanism is characterized in that a connection sleeve is additionally arranged between the motor and the flange; the bearing is installed inside the connection sleeve; and the bearing is a self-lubricating bearing.
Description
Technical field
The utility model belongs to the mining machinery class, the positive shovel excavator of particularly a kind of large-scale mine machinery.
Background technology
The exploitation scale of China's opencut enlarges gradually at present, in order to satisfy the needs of ten-million-ton scale mine construction, the demand of the positive shovel excavator of large-scale mine machinery increases gradually, is the important component of excavator and open bucket mechanism, and the reasonability of its structure directly has influence on the operating efficiency of excavator.Opening bucket mechanism is that the assurance excavator cuts out sluice gate when adopting dress, opens sluice gate when unloading.Manufacture and design and install open comparatively easily the bucket mechanism be the target that people pursue always.The positive shovel excavator of original machinery is opened bucket mechanism as shown in Figure 3, and it is made up of motor 1, reel 2, support 3, pinion 4, flange 5, bearing 6 and bearing cover 8.Motor 1 by Bolt Connection to flange 5, flange 5 is welded on the support 3, pinion 4 is fixed on the splined shaft of motor 1, reel 2 is fixed on the support 3, the driven by motor pinion rotation, mesh in the bull gear of pinion and reel, drive reel and rotate, reel realizes that by the folding and unfolding wire rope bucket of opening of excavator moves.Bucket mechanism structure more complicated left by the excavator of prior art, the Installation and Debugging inconvenience, particularly open bucket mechanism before use, the necessary unloaded test run of motor, when the empty load of motor test run, need with parts such as support, reel and pinion by flange all with ability test run after motor connects, time-consuming, require great effort inefficiency.
Summary of the invention
The purpose of this utility model is intended to overcome the shortcoming of prior art, and a kind of simple in structure, manufacturing and easy for installation is provided, and can finish out the positive shovel excavator of mine equipment of bucket empty load of motor test run simultaneously easily and open bucket mechanism.
The utility model is achieved in that
The positive shovel excavator of a kind of mine equipment is opened bucket mechanism, comprise: motor, reel, support, pinion, flange, bearing, motor connects with support by flange, pinion is fixed on the splined shaft of motor, be provided with bearing between splined shaft and the supporting member, reel is fixed on the support, the driven by motor pinion, engagement in the bull gear of pinion and reel, the drive reel rotates, it is characterized in that: set up adapter sleeve between described motor and the flange, bearing is installed in the adapter sleeve, described bearing is a kind of self-lubricating bearing.
Described motor and adapter sleeve are by Bolt Connection, and described flange connects with support by bolt with adapter sleeve.
The utility model compared with the prior art owing to set up adapter sleeve between motor and the flange, and adapter sleeve by Bolt Connection to support, made things convenient for dismounting; Simultaneously, owing in the adapter sleeve self-lubricating bearing has been installed, removed the bearing-lubricating device of original complexity from, remove parts such as bearing (ball) cover, not only simplified the structure, made things convenient for Installation and Debugging, and when the empty load of motor test run, the adapter sleeve that only needs to be equipped with self-lubricating bearing to motor, just can be finished unloaded test run with Bolt Connection, has improved operating efficiency.
Description of drawings
Fig. 1 is the schematic diagram that the positive shovel excavator of mine equipment is opened bucket mechanism;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the schematic diagram that the positive shovel excavator of original mine equipment is opened bucket mechanism;
Fig. 4 is the left view of Fig. 3.
The specific embodiment
Below in conjunction with description of drawings the utility model specific embodiment.
As shown in Figure 1, 2, the positive shovel excavator of a kind of mine equipment is opened bucket mechanism, and motor 1 passes through Bolt Connection with adapter sleeve 7, and to support 3, more original welded construction has made things convenient for dismounting by Bolt Connection for flange 5 and adapter sleeve 7.Pinion 4 is positioned at by bolt on the splined shaft of motor 1, and self-lubricating bearing 6 is installed in the adapter sleeve 7.Motor 1 drives pinion 4 and rotates, and pinion 4 and the interior engagement of the bull gear of reel 2 drive reel 2 and rotate, and reel is realized the motion that struggles against of opening of excavator by the folding and unfolding wire rope.
Described bearing 6 is selected self-lubricating bearing for use, has removed the bearing lubrication structure of original complexity from, has not promptly had bearing (ball) cover 8 parts such as grade, and is simple in structure, makes and install very convenient.When motor 1 unloaded test run, only self-lubricating bearing 6 need be installed in the adapter sleeve 7, with bolt adapter sleeve 7 is connected on the motor 1 and just can finishes unloaded test run.
