Description

A kind of method of loading, unloading and storing bulk cement and device

The invention belongs to a kind of dress, transport, unload, store up, with the method and the device of bulk cement.

Bulk cement uses from the building site of dispatching from the factory, through adorn, transport, unload, store up, with five links, wherein " fortune " is key.China mainly is that this method shortcoming is many, mainly is that the special vehicle price is expensive, the traffic cost height with special-purpose pneumatic unloading type bulk cement tanker shipping bulk cement at present; Compressed-air power consumption is big when unloading, and unloads unclean sometimes; The idle running carriage return can not utilize, and sheet pot resettlement in building site is inconvenient or the like.

Domestic for this reason had many departments and producer to release the way of using self discharging type container shipping bulk cement in recent years, for example patent 90213573.2 and 91200912.8 these two kinds of methods can adopt general wagon shipping bulk cement, but because freight container is heavier after filling cement, as if the difficulty of unloading without Special Hoisting Equipment; Again because the freight container volume is little, thus building site cement deposit problem solve bad, too high or the like the problem of center of gravity when transporting in addition in addition.

The objective of the invention is: a kind of ordinary flat Freight Transport that adopts is provided, avoids the idle running loss again, the transportation safety cost is low, unload conveniently, and solve building site storage and building site and used problem, when dry measure used in former times changes the building site, the method and the device of the use bulk cement that equipment is easy to move.

The object of the present invention is achieved like this: its device mainly comprises quantitative machine in bulk and multi-functional self-unloading storehouse.Quantitative machine in bulk is contained in the bulk cement bottom of the reservior of cement mill or transhipment station, and multi-functional self-unloading storehouse stands on the building site.When the building site needs cement, only need the several flexible pouch of ordinary flat lorry band directly under continous way volume quantitative machine in bulk, after the building site is transported in pack (seeing Fig. 1 without fork truck) on the wagon box flat board, utilize the lifting in multi-functional self-unloading storehouse and the flexible bagged cement of the handle of falling the bagging apparatus to be discharged to (see figure 2) in the self-unloading storehouse, quantitatively draw off by the quantitative gate of self-unloading storehouse feed opening again during use.When move in empty self-unloading storehouse, do not need crane, only can finish the loading, unloading turner and do with a chain block.

Further specify below in conjunction with accompanying drawing.

Continous way volume quantitative machine in bulk is installed on the discharging opening of silo funnel [2], and the hood-shaped commentaries on classics lock [3] of its cylinder stretches in the funnel [2].The end face of impeller [4] and circumference are blanking dish [5] (see figure 1) under the impeller [4] by hood-shaped commentaries on classics lock [3] the cover position of cylinder.Change the feeding mouth that has two symmetries on the lock [3], each feeding mouth all links up to periphery (side) from the end face that changes lock [3] always.Blanking dish [5] is gone up symmetry and is had two fan-shaped discharge ports, the symmetrical plane that changes the feeding mouth on the lock [3] becomes mutual plumbness to be connected on the vertical main shaft [8] with the symmetrical plane of blanking Pan Shangxieliaokou, quantitatively during discharging, motor horizontally rotates with blanking dish [5] simultaneously by deceleration system drive shaft [8] and commentaries on classics lock [3], impeller [4] keeps transfixion, cement does not unload enter the space of impeller [4] from the feeding mouth that changes lock [3] after immediately, must wait until discharge port on the blanking dish [5] forward to this space to timing, cement just unloads from this space, thereby when impeller [4] circumference encloses uniform space invariance, cement unload what promptly be proportional to the corner of main shaft [5], also be proportional to the corner of motor.Impulse deviser has been installed on motor shaft, continuous pulsing signal in discharging, when impulse singla when quantity given in advance equates, electric-control system sends control signal makes quantitative machine in bulk stop discharging.The center compartment of ordinary flat lorry [6] line of centers of the loading spout of the quantitative machine in bulk of centering [7] just in time during pack, the cement that is unloaded by quantitative machine in bulk directly is discharged in the flexible pouch that is placed on diverse location on the compartment flat board by universal telescopic spouting [72].

Multi-functional self-unloading storehouse becomes 60 ° of heeling conditions to stand on the building ground, mainly is made up of microscler storehouse [1] and bracket with foldable.There has been the H-girder [74] of reusing on its top, and the upset bucket [12] that unloads flexible bagged cement is arranged at warehouse top, and the volume adjustable proportioner is equipped with in the lower end.Under the hole capital after selling all securities state, warehouse [1] can be that rotate at the center with axle [26], and when the self-unloading storehouse was supported, support then can be dismantled and be folded up for the center by axle [26].

The aforementioned vehicular transport of bulk cement of filling is behind the building site, be retracted into earlier the middle (see figure 2) of two forelegs [9] of multi-functional self-unloading bin bracket backward, the operator is climbed up the platform [19] of upper end, top, storehouse by ladder [17] and [18], operating dolly [10] and cucurbit [11] then slings flexible pouch and being put on the upset bucket [12], untie rope [13], hang up properly the ears or side handles of a utensil [14], transfer to bayonet lock [15] to make the upset of upset bucket [12] cw pour cement in the bag in the storehouse (sack is not tangled and can fall).At this moment, the flat board on upset bucket [12] left side is translated into the dust that the right covers down sack and produce when blocking bleed.After unsnatching cement, upset bucket [12] is turned down, covered top cover [16] again with rainproof protection against the tide.Ash-unloading tube [20] can be used for accepting the bulk cement that pneumatic unloading type groove tank car ships.[21] be dust collecting sleeve, [22] are clean-out covers.

Fig. 5, Fig. 6, Fig. 7 are the hole capital after selling all securities transportation of multi-functional self-unloading storehouse and the process scheme drawing of unloading.After the building site is transported in the self-unloading storehouse, upwards dig earlier gantry arm [23] (see figure 5), and install four push bolts [24], the support that makes folded state among Fig. 5 then is that the center clockwise rotates slightly so that swivel hook [25] is turned to and draws close bulkhead with axle [26], again the support left end is put on the ground, sole [27] is outwards overturn and supports on the ground and (see dotted line position among Fig. 6).Be suspended to bottle gouard moved by hands [11] on the hangers [28] of gantry arm [23] this moment, and the lifting hook of cucurbit is suspended on the hangers [29] on the warehouse, spurs cucurbit again and make gantry arm [23] hold up solid line position to Fig. 6 together with two forelegs [9].Two curb girders [34], two back legs [30], two back soles [35] and connecting rod [31], [32], [33] (referring to Fig. 3, Fig. 4) then are installed, and bearing pin [36] is plugged at the forefoot plate place, and the front and back sole levered up pads.When the operator climbs up warehouse (Fig. 6) when spurring cucurbit [11] once more, because support is upright surely motionless, the self-unloading storehouse will be that the center clockwise rotates and leaves the dull and stereotyped (see figure 7) in compartment with axle [26], when warehouse hopper walls [37] is parallel with the compartment flat board, transport trolley can drive away, and leaves the scene.Pull on and start cucurbit [11] warehouse is erected up to state shown in Figure 3, refill front cross rail [40], the lower end of ladder [17] is fixed by bolts on the pipe link [32], the fix screw of bearing support [38] [39] is unclamped (Fig. 7), making bearing support swing to position shown in Figure 3 and use screw [39] fixing again, promptly unloads and finishes in the self-unloading storehouse.The entrucking process is with last opposite, warehouse [1] is that rotate at the center with the axle [26] on the support earlier, drop to the ground in the general wagon compartment with the control of bottle gouard moved by hands, the support in self-unloading storehouse be the center dismounting with axle [26] again and foldingly upward transports with warehouse according to paying at warehouse [1] then.

Fig. 8 is that A-A analyses and observe among Fig. 3, promptly multi-functional self-unloading storehouse double locks volume adjustable proportioner constructional drawing.Anti-fan-shaped lock [41] stretches in the storehouse, and there are two dividing plates [42] and [43] that match with anti-fan-shaped lock shape the centre below anti-fan-shaped lock [41].The bottom is two tongue locks [44] and [45], when tongue lock [44] when closing, promptly and form a certain amount of volume between anti-fan-shaped lock and the dividing plate [42], rotates the size that dividing plate [42] can change this volume.Below anti-fan-shaped lock [41], there are two actionless little fan-shaped [46] and [47] that match with anti-fan-shaped lock shape to be fixed on the lock seat [50], on little fan-shaped [46], welding little hook [49] by 8 pillars [48].Left side tongue lock [44] is gone up by bearing [51] and bearing pin [52] fork [53] that is being hinged, fork [53] other end is connecting slide bar [55] by bearing pin [54], slide bar [55] can be gone up at the riser [56] that is connected with tongue lock [44] and slide, state in the drawings, because the effect of extension spring [57], slide bar [55] upper end is not hooked and can be slided by little hook [49], thereby makes tongue lock [44] be in closed condition.Middle part at fork [53] is being connected handle frame [60] by bearing pin [58] with bolt [59], when handle frame [60] is that the center is when clockwise rotating with bearing pin [61], the pulling force that fork [53] inhour is rotated drive slide bar [55] to overcome spring [57] by bolt [59] and bearing pin [58] moves downward and makes slide bar [55] throw off little hook [49], and tongue lock [44] can be opened.

Anti-fan-shaped lock [41] is that two block-shaped identical fan-shaped side plates and a watt of shape plate are formed, and end face and side symmetry have two sector notch [73] (breach and little fan-shaped [46] and [47] shape and size match).Two cross bars [63] and [64] are symmetrically welded on the fan-shaped side plate of anti-fan-shaped lock [41].Goat's horn fork [70] is state when inhour is rotated left more in the drawings, earlier make tongue lock [45] move to solid line position among the figure (promptly closing tongue lock [45]) by dotted line position among the figure by stirring the set pin [66] that is fixed on tongue lock [45] key seat [65], goat's horn fork [70] continues the inhour rotation then, collision block [74] the bump cross bar [64] on goat's horn fork the right also drives also inhour rotation of anti-fan-shaped lock [41], even two the feeding mouth breach in the left side shown in Figure 8 are closed gradually, and open gradually on the right, when two feeding mouths in the left side are closed fully, at this moment, goat's horn fork [70] also moves to left side end position, and clash into projection [62] simultaneously, make fork [53] drive slide bar [55] and glide and throw off little hook [49], tongue lock [44] by gravity is opened and drawn off the quantitative cement in the left side.Among the figure because left and right sides tongue lock and hitch gear identical (center symmetry) and cutd open corresponding part respectively, the right tongue lock [45] is to be in handle frame [67] to cut out the back state at solid line position among the figure, dotted line position on the right of tongue lock [45] should be in when normal discharging.

Goat's horn fork is fixed together by the handle (not drawing among the figure) outside axle [68] and key [69] and the lock seat [50], thereby constantly shakes handle and make goat's horn pitch [70] reciprocally swinging, then can constantly quantitatively unload the cement in delivering from godown.When needs non-quantitative continuous discharge, can when being in opening, fan-shaped lock on one side (as Fig. 8 left side) upwards spur handle frame again, and the tongue lock is opened.Need also can close the tongue lock in the resettlement of self-unloading storehouse or other by depressing handle frame.When tongue lock [45] is in Fig. 8 dotted line position, if goat's horn fork [70] clockwise rotates and depresses, because the effect of voussoir [71] can make key seat [65] be with set pin [66] to get out of the way goat's horn fork (being that key seat inwardly rotates among the figure), when goat's horn fork [70] moves to the postpone of figure meta, under the effect of key seat [65] behind torsion spring (not drawing among the figure), reset again, make set pin [66] be in the action that the state that is tangled by goat's horn fork [70] can recover front continuous and quantitative discharging.

The advantage of the inventive method is as follows:

1, ration bulk machine of the present invention can be φ 600 at the bottom of the reservior feed opening, absolute altitude only is directly to realize quantitatively pack or entrucking (without crane and fork truck) under 4 meters the storehouse in bulk, the comprehensive power consumption of ration bulk machine only is 1/3 of domestic non-quantitative bulk machine product, and the 1/10(that the investment of ration bulk machine is about the investment of measuring chute system does not include the fork truck investment).
