Abstract

The utility model relates to a hydraulic cleaner, and the crossbeam is fixed on the existing wall or the wall column. The crossbeam is provided with a roadster, and a grab bucket is arranged on the roadster through a lifting arm. The roadster is driven by an oil cylinder or an oil motor to move to left or right for a certain distance on the crossbeam above the midpoint of an orbit, and the grab bucket is connected with the lifting arm by the hinge form. The utility model has the advantages of simple structure and high stability and is suitable for using on the well and under the well. The time for cleaning the sticky bottom of the tram is matched with the tipper ability, and the utility model has the linked function of the three machines. The residual coal after the mine car with normal sticky bottom is cleaned is lower than 1.6% of the dead weight of the carriage, so the effect is good.

Description

Fixed crossbeam type hydraulic cleaner for tram
The utility model is by the 37 page of disclosed that class descaling machine development of in 1982 the tenth first phases of China's " coal science and technology " magazine.
In order to clear up the bonding residue in the mine car railway carriage in transportation coal and other mineral process, the mine car cleaning equipment is absolutely necessary.In known hydraulic punch machine, crossbeam is installed on the portal frame, can be under the driving of oil cylinder in vertical direction along the portal frame up-and-down movement, and its basic component of portal frame is connected with the basis, ground with holding-down bolt.Sport car is contained on the crossbeam, can be along the length direction sway of crossbeam.The grab bucket of two and half wooden dipper shapes is directly installed on the sport car.Grab bucket is closed up with the slide block connecting rod method of synchronization under the promotion of oil cylinder, digs 1 shovel and needs 40~50 seconds, and general 3 shovels just can dig clearly at the bottom of the car.This hydraulic punch machine stability is poor, be installed in shaft station chamber and ground car dumper shed and use the basis of easy and miscellaneous equipment to produce interference, and cleaning effect is undesirable.In addition, slide block connecting rod synchronizer gear structure more complicated, setting accuracy requires high, and friction drag is big.
Task of the present utility model is a kind of upper and lower use of well, reliable working performance, hydraulic punch machine that cleaning effect is good of being suitable for of design.
Task of the present utility model is resolved by following mode.With the beam design posture of embarking on journey, connect with threaded anchor rod and directly to be fixed on the cave wall of shaft station, shown in Figure 2.Or be fastened on the wall column of car dumper shed ferro-concrete shown in Figure 1.Crossbeam is parallel with the tramroad face and keep certain distance, becomes solid space perpendicular with track.Sport car (3) is housed on the crossbeam (2), grab bucket (4) is installed on the sport car (3) by lifting arm (1), and sport car (3) is driven by oil cylinder or oil motor and is connected on the lifting arm (1) with the hinge form in the certain distance that moves right left on the crossbeam above the track mid point, grab bucket (4).In order to improve cleaning effect, again to the grab bucket oad and have related parameter to make new design drawing 3 to shown in Figure 5.When grab bucket volume and grab bucket end and railway carriage make a slip of the tongue the machine gap definite after, under the certain setting height(from bottom) influence of crossbeam, the main scraper plate (2) of grab bucket contacts the influence that arc wheel profile partly directly is subjected to the inner surface contour line of mine car length direction vertical cross-section with the railway carriage inwall.20~30% of the general assembly Capacity Selection mine car railway carriage total volume of grab bucket, more rational.Therefore main scraper plate (2) contacts arc wheel profile partly and should get that a part of curve that radius of curvature is tending towards minimum by following elliptic equation curve with the railway carriage inwall.Elliptic equation is: X 2+ y 2COS 2α=(B 2)/4 (elliptical center is on origin of coordinate) are wherein: B---be the width of mine car inner chamber
α---half of two main scraper plate angles when closing up for grab bucket.It is proper between α gets 50~55.The both sides of grab bucket are made of side plate (1), pair scraper plate (3), pair scraper plate (4).Side plate (1), a pair scraper plate (4) are surface plate, and paying and scraping (3) is arc.Pay scraper plate (3) front end the CD section, pay the elliptic curve of their projections on mine car length direction vertical cross-section of DE section of scraper plate (4) corresponding to main scraper plate outline line C ' D ', D ' E ' section.C ' G, D ' H, the projection on vertical cross-section of E ' T straight line, its line segment spacing are chosen by (B)/6~(B)/5, (B)/7~(B)/6, (B)/19~(B)/14 respectively.In addition, also the synchronizer gear of grab bucket has been done improvement.Adopt the four-bar mechanism of compositions such as a pair of crank, connecting rod, fork to realize.Its synchronizer gear as shown in Figure 6.When grab bucket cylinder piston rod (3) elongation, the fork on the left side (1) inhour swing certain angle, (fork (6) cw that 2) La Dong rotation rotating disks (4) clockwise rotate on the right of promoting by connecting rod (5) again when corresponding angle rotation rotating disk (4) rotates is also swung corresponding angle by connecting rod, grab bucket just can be closed up simultaneously, when grab bucket oil cylinder piston bar shortens inward, the swing of fork (1) cw, promote connecting rod (2); rotation rotating disk (4) inhour is rotated, by the corresponding angle of connecting rod (5) pulling fork (6) inhour swing, grab bucket is opened simultaneously.
Compare with known hydraulic punch machine, this machine good stability, simple in structure, dependable performance adapts to the upper and lower use of well, can be directly installed on the manufacturing line and the supporting use of the electronic tipper of standard, and the sticking time end of its cleaning mine car and tipper ability are complementary.The function that also has three machines (car puller, tipper, descaling machine) interlock simultaneously.Be convenient to centralized control, simple to operate.The residual coal in mine car cleaning back at the normal sticking end accounts for below 1.6% of railway carriage gross deadweight, and is respond well.
An embodiment of the present utility model has been described in the accompanying drawing.
Fig. 1: the utility model is installed in the ground scheme drawing.
Fig. 2: scheme drawing under the utility model mounting shaft.
Fig. 3: grab bucket lateral plan.
Fig. 4: grab bucket front view.
Fig. 5: the appearance profile line scheme drawing of the main scraper plate of grabbing bucket.
Fig. 6: crank rocking beam synchronizator composition.
Fig. 7 to Figure 10 is trusk cleaner grab bucket operating mode scheme drawing.
Described the descaling machine that is used for residue in the cleaning mine car among Fig. 2, its work partly crossbeam (2) is fixed on the cave wall in parking lot, down-hole, connects with threaded anchor rod.The rocking arm (2) that grab bucket (4) are housed is contained on the sport car (3), can be along vertical and horizontal motion, and prime power (5), electric cabinet (6) connect by cable and oil pipe line and operate portions.
Fig. 7 to Figure 10 has described the operating mode scheme drawing of the grab bucket of descaling machine described in Fig. 2.After mine car puts in place,, can realize all processes of automatic cleaning mine car by the electrical controller and the hydraulic actuator of this machine.Be that sport car is back to the mine car top, after the interior certain position of mine car was stretched in the grab bucket of half open configuration, grab bucket was opened and railway carriage two end in contact fully, mine car automatic compensation good position, and grab bucket is inserted shown in the mine car base map 7 along the railway carriage two ends.Grab bucket to close up then residue is cleaned out, shown in Figure 8.Lifting arm drives the grab bucket lifting and leaves the certain distance of railway carriage mouth, and is shown in Figure 9.Sport car is pushed to the unloading point top, opens grab bucket residue is discharged into.Shown in Figure 10.
