Specific embodiment
The core of the utility model is to provide a kind of wheel rim slag-scraper, can reduce the impact generated to wheel rim.
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with attached drawing and
Explanation is described in detail to the wheel rim slag-scraper of the utility model in specific embodiment.
As shown in Fig. 2, the schematic diagram of the wheel rim slag-scraper for the utility model, the circle of lower section is wheel rim；The device
Including clamping oil cylinder 1, the lower rod cavity and upper rod cavity for clamping oil cylinder 1 are separately connected reversal valve 2, up and down shown in Fig. 2 of this paper
Direction be illustrated；By oil pump 3 to clamping 1 fuel feeding of oil cylinder, the hydraulic oil that oil pump 3 pumps changes reversal valve 2 by reversal valve 2
It changes direction, so that the piston rod for controlling clamping oil cylinder 1 such as rises or falls at the motion states.
Speed governing valve 4 is set on the oil circuit of rod cavity on the connection clamping oil cylinder 1 of reversal valve 2, speed governing valve 4 is for adjusting to clamping oil
The The hydraulic oil that cylinder 1 conveys changes the movement speed of piston rod by The hydraulic oil.
Clamping piece 5 is arranged in the piston rod bottom end for clamping oil cylinder 1, and clamping piece 5 and piston rod are relatively fixed, and the two is synchronous to be risen
Drop；The bottom of clamping piece 5 slides vertically flexible setting upper clamp 51, and upper clamp 51 can slide vertically relative to clamping piece 5, by pressing from both sides
Gripping member 5 plays guiding role to upper clamp 51；Elastic component 52 is set between upper clamp 51 and clamping piece 5, and elastic component 52 is to upper pincers
Body 51 provides downward elastic force, and upper clamp 51 is made to have the tendency that stretching out in clamping piece 5 downwards.
Pressure sensor is arranged in the bottom of upper clamp 51, and pressure sensor can be contacted with wheel rim, detection upper clamp 51 and wheel
Pressure size between rim；And speed governing valve 4 adjusts hydraulic fluid flow rate according to pressure sensor pressure signal, and flow increases with pressure
Big and reduces namely pressure gets over that big flow is smaller, the speed of piston rod and the decline of clamping piece 5 is slower.
When work, upper rod cavity oiling of the reversal valve 2 to clamping oil cylinder 1, piston rod drives clamping piece 5 to move down, and clamps
Upper clamp 51 is first contacted with wheel rim after part 5 moves down certain distance, due to being equipped with elastic component between upper clamp 51 and clamping piece 5
52, it is smaller to the impact force of wheel rim；The vertical position of upper clamp 51 remains stationary, and 5 compression elastic piece 52 of clamping piece continues to decline,
Until clamping piece 5 and upper clamp 51 contact firmly, realizes and complete to press；During clamping piece 5 continues decline, elastic component
52 suppressed range is gradually increased, and is gradually increased to the pressure of wheel rim, and the signal control of pressure sensor detection adjusts valve 4 to reduce stream
Amount, is gradually reduced the decrease speed of piston rod, until clamping piece 5 contacts stopping with upper clamp 51 firmly, whole process will not be right
Wheel rim causes to impact, and avoids generating damage.
Further, clamping piece 5 is U-shaped, and Open Side Down, and Liang Ge branch extends downward；U-shaped two points of clamping piece 5
The channel opened downward is respectively set in branch, elastic component 52 is set in channel, and elastic component 52 is to be set in 5 channel of clamping piece
Compressed spring, a part of compressed spring exposes to clamping piece 5, and upper clamp 51 is plugged in compressed spring, compressed spring
One end is contacted with clamping piece 5, and the other end is contacted with upper clamp 51, and upper clamp 5 is made to keep down the trend of stretching.
In order to clean hydraulic oil, filter is set between the oil inlet and fuel tank of oil pump 3.
Preferably, the reversal valve 2 in the utility model is three position four-way electromagnetic valve, also be can be selected other kinds of hydraulic
Valve.
On the basis of any of the above-described technical solution, the upper piston area fixed setting that oil cylinder 1 is clamped in the utility model is pushed away
Lever 6, as shown in figure 3, being located in upper rod cavity for clamping oil cylinder 1 and the mutually matched structure chart of catch bar 6, catch bar 6；It pushes
Bar 6 and the cylinder sleeve holding of clamping oil cylinder 1 are slidingly sealed, and catch bar 6 can stretch in cylinder sleeve, the length of catch bar 6 outside top
It is larger, sliding contact sealing is kept with the cylinder sleeve of clamping oil cylinder 1 always in lifting process.
Catch bar 6 opens up cavity upward, is equivalent to blind hole, and screw rod 61 is used for the cavity protruded on catch bar 6, screw rod 61 with
The inner cavity of catch bar 6 not in contact with；Screw rod 61 is moved up and down by the nut rotation realization of its cooperation, can when moving down
The bottom surface of 6 inner cavity of catch bar is contacted, pushes the piston rod of clamping oil cylinder 1 to move down, screw rod 61 does not pull when moving down
Catch bar 6, catch bar 6 are moved up by piston.
It is pushed by screw rod 61 and two kinds of drive forms of hydraulic-driven of reversal valve 2, realizes two kinds of pushing courses, clamped
The cylinder sleeve of oil cylinder 1 remains relatively fixed；In initial phase, first passes through screw rod 61 and move down pushing catch bar 6, until pressure
Until force snesor detects pressure signal, this process can be realized rapid decrease, improve processing efficiency.Later by reversal valve 2
Hydraulic drive piston bar move down, realize stablize and move down at a slow speed.
Further, the upper rod cavity and lower rod cavity that oil cylinder 1 is clamped in the utility model are respectively by independent with 2 phase of reversal valve
Repairing piping connection fuel tank, the shut-off valve 7 of setting control oil circuit on-off on repairing pipeline.When screw rod 61 drives and declines, beat
Shut-off valve 7, the upward rod cavity repairing of fuel tank are opened, the oil of lower rod cavity enters fuel tank；It is moved down by the hydraulic drive piston bar of reversal valve 2
When, close shut-off valve 7.
As shown in figure 4, being the chart at the bottom of of upper clamp 51, the bottom of upper clamp 51 is removably disposed upper fixture block 55,
The bottom of upper clamp 51 is L-shaped, and upper fixture block 55 is fixed by vertically arranged bolt 53 and the bottom surface of upper clamp 51；Upper fixture block 55
Side wall protrusion setting stud 54, stud 54 pass through upper clamp 51 side wall and fixed by nut.Upper fixture block 55 is removably
It is fixed on the bottom of upper clamp 51, can be convenient and replace different upper fixture blocks 55, the wheel rim applied to different-diameter.
When installation, aperture in 54 aligned sidewalls of stud, the side wall of the laterally inserted upper clamp 51 of upper fixture block 55, and by nut
It is fixed, then it is inserted into bolt 53 from bottom to top, upper fixture block 55 realizes more stable peace by fixing at stud 54 and 53 liang of bolt
Effect is filled, the excessive generation damage of local stress is avoided.
