In order to achieve the above purpose, the utility model adopts the following technical means: the utility model provides an internal mixer locking device, includes locking hydro-cylinder, locking seat, locking bolt, the locking seat sets up two, and the symmetry is installed on water end limit support and drive end limit support, sets up a cavity that has the direction and is good for the groove in the locking seat, the locking hydro-cylinder sets up two, installs the one end at the locking seat cavity that corresponds respectively, the locking bolt sets up two, and the telescopic link of locking hydro-cylinder is connected to the one end of locking bolt, and the side of locking bolt is good for the direction slip setting in the cavity through the direction of installing in the direction is good for the inslot, all sets up a roller bearing in the bottom both sides of the gate seat of unloading, all installs a roller bearing cover outside two roller bearings, two locking bolts respectively with the roller bearing cover crimping of place side to it is parallel with the gate shaft of unloading.
The roller shaft and the roller shaft sleeve are symmetrically arranged on the discharging door seat, the locking seats are symmetrically arranged on the water end and the driving end side bracket, the locking bolt is driven by the locking oil cylinder and slides in the locking seats through the guide key to move in a guide manner, and the moving position is ensured to be accurate. When the locking bolt stretches to the locking position, the locking bolt contacts with the rolling shaft sleeve, the left and right 2 locking bolts simultaneously complete locking on the discharging door seat, and the locking bolt stretches in the locking seat to reach the corresponding locking and unlocking positions, so that the locking direction is parallel to the discharging door shaft.
Furthermore, the locking oil cylinder is fixed on the locking seat through an oil cylinder flange.
Furthermore, the compression joint surface of the locking bolt and the rolling shaft sleeve is set to be the same arc as the compression joint surface of the rolling shaft sleeve, and the rolling shaft sleeve is in rolling friction with the locking bolt.
The beneficial effects of the utility model reside in that: the left side and the right side are synchronously locked, and the stress is symmetrical; in the locking process, the rolling shaft sleeve and the locking bolt are in rolling friction, so that the abrasion of parts is small; the locking direction is parallel to the discharging door spindle, and the discharging door spindle cannot be extruded, so that the whole internal mixer operates more stably, the service performance of the equipment is improved, and the maintenance period of the equipment is prolonged.
Drawings
The invention is further explained below with reference to the drawings and examples.
Fig. 1 is a schematic partial cross-sectional view of the present invention;
fig. 2 is a schematic structural diagram of the prior art.
In the figure: 1. locking the oil cylinder; 2. an oil cylinder flange; 3. a water end edge support; 4. a locking seat; 5. a guide groove; 6. locking the bolt; 7. a roller; 8. a rolling shaft sleeve; 9. a discharge door shaft; 10. a discharge gate seat; 11. driving the end edge support.
Detailed Description
As shown in the prior art schematic structural diagram of fig. 2, the discharging device is fixed on the side bracket through the discharging door shaft, and the locking device is fixed on the base. The stress of the whole locking device is finally transmitted to the locking base, and because the instant impact force of the internal mixer in the working process is very large, the connected bolts are loosened and even broken; in addition, when the locking device is locked, the discharging door shaft is radially extruded greatly, so that the discharging door shaft is not stressed uniformly, and the discharging action is not smooth.
In order to solve the problems, the applicant organizes technical challenges and provides a new structural mode.
As shown in fig. 1's banbury mixer locking device, including locking hydro-cylinder 1, locking seat 4, locking bolt 6, locking seat 4 sets up two, and the symmetry is installed on water end limit support 3 and drive end limit support 11, sets up a cavity that has the strong groove 5 of direction in locking seat 4, locking hydro-cylinder 1 sets up two, installs the one end at the 4 cavities of locking seat that correspond respectively, locking bolt 6 sets up two, and locking hydro-cylinder 1's telescopic link is connected to locking bolt 6's one end, and the side of locking bolt 6 is good at the cavity in the direction slip setting through the direction of installing in the strong groove 5 of direction, and the material of feather key is tin bronze. All set up a roller bearing 7 in the bottom both sides of door seat 10 of unloading, all install a roller sleeve 8 outside two roller bearings 7, two locking bolts 6 respectively with the roller sleeve 8 crimping of place side to it is parallel with door axle 9 of unloading, the locking direction is parallel with door axle 9 of unloading, can not produce the extrusion to door axle 9 of unloading. The locking oil cylinder 1 is fixed on the locking seat 4 through an oil cylinder flange 2.
