The present invention mainly dismantles the punctured wheels from the vehicle body to repair them when the wheels of a large vehicle are flat, and then, as a separator of the present invention, the tires and wheels of the dismantled wheels can be easily and quickly separated. In particular, the present invention relates to a tire wheel separator of a wheel, and in particular, the present invention is configured to retract the piston in which the wheel of the wheel is installed (the piston moves into the cylinder) and pulls the wheel and prevents the tire from both sides of the wheel. The purpose is to move the initial position of the inner surface of the tire to be attached to and loosen so that separation of the wheel and tire can be easily performed.

The present invention will be described in more detail. One side of the lower frame with wheels freely moves and installs an annular injector with cylinders having forward and backward movement means by pneumatic and hydraulic pressure on both supports. Several stopper pieces which block the side wall of the wall extend a certain angle, and a support plate of two sections is installed between each of the stopper pieces, and the insertion base is elastically installed therein, but the installation diameter of these stopper pipes is It is configured to be smaller than the diameter of the annular pressure port and protrudes longer than the stopper piece so that each insertion stopper can dig into the enlarged part formed at both sides of the wheel and the back part of the binding ring to push the inner end of the tire. Make sure

In addition, on the other side of the lower frame, an oil tank and a debris were installed to supply the hydraulic pressure and pneumatic to the inside and the rear of the cylinder. The hydraulic and pneumatic supply and recovery operation is carried out by a four-way valve and a booster valve. It is configured to carry out the pneumatic supply system, so that the piston of the cylinder can be moved forward and backward, and on the lower frame there is a lifting plate body and a roller for elevating the wheel.

Therefore, the flat wheel is placed on the roller of the lifting plate body, and then the manual steering wheel is rotated to raise the wheel to the proper position, that is, the height of the center hole of the wheel at the position of the center of the fitting of the piston tip. The piston, supplied with pneumatic pressure in the back of the cylinder with a piece of 4-way valve, starts the forward operation (the piston exits the cylinder), so that as soon as the engagement port of the piston tip enters the center hole of the wheel, The four-way valve is operated to the neutral position to stop the piston's forward operation, and then the wheel is firmly fixed to the end of the piston by means of engaging the circular binding plate to the coupling hole. 4-way valve operation of the piston is rotated in the opposite direction than when the battery is charged so that the hydraulic pressure is injected into the front of the cylinder Causes a stone wheel is hameuroseo to the reverse operation moves toward the annular apgu.

As such, when the tire side wall of the wheel, which is attached to the front end of the piston that is driven backward by the hydraulic injection operation of the four-way valve, touches the end of the insertion plate that protrudes further forward than the stopping stone of the annular pressure port, the tire itself is slightly damaged by the hydraulic pressure. In addition, the insertion stopper itself is intended to dig into the enlarged portions formed on both sides of the wheel or the back side of the binding ring while compressing the spring, and the hydraulic force at this time is simply the air compression force of the compressor by the four-way valve operation. Only a large amount of pressure does not work enough to push the side wall of the tire.

Therefore, when the tire side wall of the wheel is in close contact with the insertion stopper plate, operate the 4-way valve to the neutral position, and then operate the booster valve so that the booster supplies hydraulic pressure to the inside of the front of the cylinder at an increased pressure. The wheel is pulled at a higher pressure. Accordingly, the insertion stopper and the stopper block restrain the tire sidewall with a high pressure, so that the inner contact surface of one side wall of the tire can slide on the outer peripheral surface of the wheel. It is configured to dig into the enlarged part of the wheel or the back part of the binding ring and push the end of the four tire contact surfaces so that the inner contact surface is slipped and loosened so that the tire sidewall is pushed forcibly as in the prior art. When the pressured side wall enters inward, the pressure is shown by the arrow shown in FIG. It acts as an axle and prevents the internal surface from being damaged by pushing the outer surface of the wheel, which can be easily and quickly separated from the tire without reducing the service life of the tire. I would have to.

In general, when a wheel with a tube is punctured, it is necessary to remove the wheel fitted to the tire to repair the tube. The tire's inner surface of the wheel is firmly attached to the outer circumference of the wheel. The tire inner surface melts due to the friction heat generated when the tire rubs against the ground during weight and running, so the separation work is very difficult and difficult.

Therefore, in order to impact the tire so that the inner surface attached to the outer circumferential surface of the wheel falls, the impact of the side wall of the tire using a hammer, a pickaxe or an iron rod is applied to the enlarged portion of the wheel and the backside of the picking ring or the iron rod. Inserting the pointed end and performing the same operation as the lever action, such artificial work was a slow time to separate the tires and wheels, especially the use of a lot of force.

The present invention was devised to eliminate all the defects of the prior art, and it is the first operation of the tire's inner surface which is melted on the outer circumferential surface of the wheel by pulling the tire and wheel separation operation as a cylinder operated by hydraulic pressure and pneumatic pressure. I slide it in a position and am complete. The purpose of the present invention will be described in detail with reference to the accompanying drawings so that the separation can be performed very easily and thus the separation can be performed much more easily, thereby allowing the puncture or the tube to be repaired quickly. As follows.

1 to 3 is a configuration of the whole perspective view showing the configuration of the separator of the present invention and the cross-sectional view showing the operating state, the front of the bottom of the lower frame (1) is attached to the wheel (2) for easy installation. On the one side (upper right side) of the lower frame, both support angles (3) and (3 ') are erected and the rear side of the annular pressure port (5) formed with a sturdy reinforcement framework (4) formed at the upper end thereof. And the cylinder 7 in which the piston 6 which drives a mole was installed was installed horizontally.

In the front end of the annular pressure port (5), the stopper piece (8) having punched through hole (8 ') protrudes at an isometric angle, and the outer peripheral surface toward the concave inlet (8 ") formed between each of the stopper pieces (8). Each pair of support plates 9 protrude from each other, and a stop plate 10 for insertion is attached to an upper end thereof so as to be elastically supported by the springs 12 on the protrusions 11 protruding from the outer circumferential surface rear side of the recessed part 8 ". The stopper plate 10 for insertion was elastically installed as the tungsten rod 13, and the installation angle of the stopper plate 10 for its insertion was about 45 degrees and was installed in an inwardly inclined state toward the front of the annular pressure port 5. In addition, the installation state of the insertion blocking plate 10 is the state under the initial state (before operation) is at least not larger than the installation inner diameter of the stopping stone piece 8 and larger than the outer diameter of the wheel (W) The stopper plate for insertion 10 starts the crimping operation and starts digging into the back portion of the outer diameter of W (W). The inner diameter of the distal end of the insertion stop plate 10 is reduced while the tire T is in contact with the outer circumferential surface of the wheel W until the pressure is almost reached by the compression reaction force of the compressed tire T. It is configured to apply a compressive force to the end surface of the internal contact (T ') side of the.

In addition, the piston tip of the cylinder (7) installed in a fixed state on the center of the reinforcement skeleton (4) of the annular pressure inlet (5) fixed to the upper support angle (3) (3 '), the front of the reinforcement bone diameter (4) Protruding to the side of the disc (6 ') and the rectangular coupling sphere (6 ") is formed, this rectangular coupling sphere (6") is to be coupled to the rectangular hole (14') of the circular binding plate (14), The circular binding plate 14 is provided with a stopper 15 and two handle bars 16 and 16 '.

On the other side of the lower rail (1) (left side of the drawing), four operation rods 17 are provided with an operation control device 18, and the operation control device 18 is an oil tank 19 and a booster device 20. And a hydraulic circulation valve unit 21 and a hydraulic pressure regulating valve 22, four-way valves 23 and booster valves 24 for operating hydraulic and pneumatic supply operations are provided therein. It is installed on the upper surface of), and the driving force to operate these is by the compressed air pressure of the compressor (Compressor) and also by the operation of the four-way valve 23 and the booster valve 24 to operate the hydraulic and pneumatic The system line is configured, and the hydraulic and pneumatic system line configuration and operation description will be described later.

On the upper surface of the lower frame 1 configured as described above, a lifting plate body 25 and a roller 26, 26 'for lifting and lowering the tire T are installed, and the lifting plate body 25 has a rear support angle at both sides thereof. (3) It is installed in the state of being guided between the (3 '), the support protrusion (25') protruding on both sides of the rear portion, the shaft bar 28, the chain guide roller 27 is bonded freely rotatable The elevating operation of the elevating plate body 25 is a rotational operation of the handle 30 of the handle shaft 30 'extending long in the small chain device 29 fixed to the rear surface of the annular pressure port 5. One end of the chain 31 inserted into the chain origin device 29 is hooked to the lower side of the chain guide roller 27, so that the back side of the annular pressure port 5 is formed. The fixed end 32 is fixedly connected to the lower side, and the other end of the chain 31 is drawn out of the chain guide roller 27 to be in the free end state. To do that.

Then, the connecting rods 34 and 34 'are attached to the inner surface of the roller sections 33 and 33' which are in contact with the rollers 26 and 26 'in a downward state, and are formed on the upper surface of the other side of the lower frame 1. A fixed linkage 35 (35 ') is formed, and the upper and lower pairs of links (36, 36') are connected between the electrical linkage 34 (34 ') and the fixed linkage (35) (35'). The elevating plate body 25 when the chain 31, which is rolled up or down on the chain device 29 by the rotation operation of the handle 30 and raises or lowers the chain guide roller 27, is connected to ) And the rollers 26 and 26 ', the upper and lower pairs of links 36 and 36' maintain horizontality, so the lifting operation is smoothly performed as a horizontal state.

In addition, the front frame of the lower frame (1) is provided with a guide 38, which can be raised and lowered by rolling the tire (T) by the hinge 38 coupling.

The state of use of the present invention configured as described above will be described in more detail by combining the operation configuration of the hydraulic and pneumatic system diagrams of FIGS. 6 and 7 as follows.

First, as shown in FIG. 1, the piston 6 installed in the cylinder 7 is fully retracted and then lowered as a means for rolling up the flat wheel using the guide foot 37 installed in an inclined state. When the wheels are raised on the rollers 26 and 26 ', the wheels are placed above the lower frame 1 in a stable state by the two rollers 26 and 26', and then the operator lifts the handle 30. When the clockwise rotation operation is performed, the chain drive device 29 operates to wind up the chain 31, so that the chain 31 is wound up into the chain drive device 29 and lifts up the chain guide roller 27. And the lifting plate body 25 which comprises the shaft bar 28 in an integrated state is raised, and at this time, the connecting rod 34 (33) (33 ') welded to the front end of the lifting plate body 25 ( 34 ') is connected between the upper and lower pairs of links 36 and 36' extending in an adhesive state. Therefore, even if the elevating plate 25 itself receives the biased upward force, the elevating operation is performed in a horizontal state by the inter-links 36 and 36 ', and the elevating plate body 25 has both support angles (3). ) The horizontal movement state becomes smoother because it is sandwiched between (3 ').

At this time, the free end of the chain 31 wound up by the chain device 29 is in a state where the chain 31 rolled up to the chain guide roller 27 rolls down while being stretched down, and the handle 30 When the rotation operation of the chain is stopped, the chain 31 itself is locked by the internal locking device of the chain priming device 29, so that the lifting plate body 25 is not naturally lowered by loads such as wheels.

By moving the wheel up and down in this manner, the center hole W 'of the wheel W is positioned at the center position of the annular pressure port 5, that is, at the position where the rectangular coupling hole 6 "of the tip of the piston 6 is inserted. When it reaches, it stops the operation of raising the handle 30. As shown in the phantom line part of FIG. 2 which advances the piston 6, the rectangular coupling hole 6 "passes through the center hole W 'and the disc 6 'is in contact with the wheel W. At this time, the forward movement of the piston 6 is operated by the four-way valve 23, and only the pneumatic pressure of the compressor COMF is supplied into the rear of the cylinder 7. It consists of the operation, and the pneumatic and hydraulic supply and circulation system at this time is described as a schematic diagram of FIG.

First, the compressed air pressure of the compressor (COMF) separately installed through the four-way valve 23 and the booster valve 24, the respective devices of the operation control device 18, that is, the oil tank 19, the booster device 20, First, the connection configuration of each hose, which is a system path for supplying the hydraulic circulation valve device 21 and the cylinder 7, and also the connection configuration of the hydraulic hose, first, the pneumatic hose (a) connected to the compressor (COMF) is a four-way valve. (23) and the inlet (23a) (24a) of the booster valve 24 in series, and the hose (b) connected to the other inlet and outlet (23b) of the four-way valve 23 is connected to the cylinder (7) It is connected to the communication port (7 ') connected to the rear inside, and further connected to the upper communication port (21') of the hydraulic circulation valve device 21 by connecting another hose (b ') on the hose (b) give.

In addition, the hose (C) connected to the other inlet and outlet 23C of the four-way valve 23 is connected to the constant communication port (19 ') of the oil tank 19 in series, the outlet of the four-way valve (23) 23d is configured to discharge the air to the outside, the inlet 23a, inlet and outlet 23b (23c) and outlet 23d by the left and right rotation operation of the operation lever 23 'of the four-way valve 23. ) Can be relatively open or closed.

The outlet 24b of the booster valve 24 is connected to the pneumatic inlet 20 'at the rear of the booster device 20 as one hose d, and two hydraulic inlets are provided at the front side of the booster device 20. 20 "and the hydraulic discharge port 20" 'are formed, the hydraulic suction port 20 "is connected in series with the hydraulic communication port 19" and the hydraulic hose A of the oil tank 19, On the hydraulic hose (A), a hydraulic hose (A ') for supplying and recovering hydraulic pressure to the hydraulic side circulation port (21 ") of the hydraulic circulation valve device 21 is connected, and also the hydraulic pressure down of the hydraulic circulation valve device (21). The hydraulic hose D 'connected to the circulation port 21 "' connects the hydraulic discharge port 20" 'of the booster device 20 with the hydraulic communication port 7 "communicating with the front interior of the cylinder 7. The hydraulic inlet 22 'side of the hydraulic pressure regulating valve 22 is connected to the hydraulic hose D, and the hydraulic outlet 22 is connected to the hydraulic hose D. Jumyeo connected to the bus (A '), it was also has installed the pressure cage 40, the hydraulic pressure control valve 22.

In addition, the internal configuration of the hydraulic circulation valve device 21, the pressure is elastically installed by the spring 42 on the bottom of the rubber material pressing plate 41 which is pressed by the pneumatic pressure flowing into the upper communication port (21 '). The spring 43 is supported by the cylinder 43 and the operating cylinder 45 for opening and closing the ball valve 44 by the pressure cylinder 43.

Here, the ball valve 44 for opening or closing the hydraulic axial circulation port 21 "and the hydraulic downward circulation port 21" 'of the hydraulic circulation valve device 21 in a communication state is small and large as shown in the example of the system diagram. Instead of having two ball valves 44, only one of them may be configured to a size that allows a large amount of hydraulic pressure to be circulated at high speed.

As described above, the operation process for engaging the wheels W of the wheels by advancing the piston 6 as described above, and connecting the operation lever 23 'of the four-way valve 23 as shown in FIG. When operated to the left side as in the solid line portion, the inlet port 23a and the inlet port 23b are in communication with each other, and on the contrary, the inlet port 23c and the outlet port 23b on the other side are in communication with each other.

Therefore, the extruded air supplied from the operating compressor is supplied to the four-way valve 23 and the booster valve 24 through the hose a, but the booster valve 24 is closed in a state where no pressing operation is performed. Since the pneumatic pressure is supplied to the inlet port 23a of the four-way valve 23, the pneumatic pressure is supplied to the hydraulic circulation valve unit 21 through the hoses b and b 'as shown in the solid arrow direction. It is supplied to the upper portion of the upper portion and the rear of the cylinder (7), wherein the pneumatic pressure flowing into the upper portion of the hydraulic circulation valve device 21 presses the rubber pressing plate (41) while the operation between the pressing section (43) ( 45 maintains the state in which the ball valve 44 is operated in the open state while the springs 42 and 46 are elastic, and the pneumatic pressure continuously supplied by the continuous operation of the compressor is inside the rear of the cylinder 7. To the piston (6) to advance the operation, When the hydraulic pressure existing inside the cylinder (7) in the front is discharged to the hydraulic communication port (7 ") of the front side, the hydraulic circulation valve device constituting an open hydraulic passage along the hydraulic hose (D) (D ') The piston 6 itself is circulated back to the oil tank 19 through the hydraulic hose A 'connected to the hydraulic axial circulation port 21 "as the hydraulic down circulation port 21"' of 21). Since the forward operation is performed while the hydraulic pressure is discharged by the supplied pneumatic pressure, the rectangular coupling hole 6 "of the piston 6 can pass through the center hole W 'of the wheel W of the upwardly adjusted wheel. By operating the four-way valve 23 to the neutral position at the moment when the disc 6 'of the piston 6 contacts the outer surface of the center hole W' of the wheel W, the supply state of the pneumatic pressure is stopped. Since 6 can be stopped at a desired position, a rectangular texture is formed in the rectangular hole 14 'of the circular binding plate 14 as shown in FIG. While holding the handle bar 16 or 16 'at the same time as inserting the sphere 6 ", the stationary coupler 6" and the rectangular hole 14' are displaced and fixed while being offset. As the hooks 15 are caught by the fittings 6 ", their joining operations are easy.

After the forward operation of the piston 6 is posted, the wheel W is attached to the tip of the piston 6, and then the operating lever 23 'of the four-way valve 23 is moved as shown in FIG. When it is operated to the right side, the oil filled in the oil tank 19 flows into the front of the cylinder 7, and the pneumatic supply process at this time is the inlet port 23a of the four-way valve 23 and the inlet and outlet port 23c of the other side. Is in communication with each other, while the inlet and outlet 23b and the outlet 23d are in communication with each other, so that the pneumatic pressure of the compressor is through the inlet 23a of the four-way valve 23 and the inlet and outlet 23c of the other side. As the hose (C) flows into the upper portion of the oil tank 19 to discharge the hydraulic pressure to the hydraulic communication port (19 "), a part of the discharged hydraulic pressure booster device 20 through the hydraulic hose (A) It is introduced into the hydraulic suction port (20 ") of the supply through the hydraulic discharge port (20" ') is supplied to the hydraulic hose (D), and also to the hydraulic hose (A) Part of the hydraulic pressure bypassed to the connected hydraulic hose (A ') flows into the hydraulic side circulation port 21 "of the hydraulic circulation valve device 21, wherein the supply of pneumatic pressure is supplied to the upper side of the hydraulic circulation valve device 21 Pneumatic pressure is discharged to the upper communication port 21 'by the self restoring force of the rubber material pressing plate 41 and the restoring force of the springs 42 and 46, which are not in the state. It is discharged to the discharge port 23d of the valve 23, and thus the ball valve 44 is maintained in a state of closing the hydraulic side circulation port 21 ", but is introduced into the hydraulic side circulation port 21". Since the hydraulic pressure acts to open the ball valve 44, the hydraulic pressure flowing therefrom opens the ball valve 44 and simultaneously flows out to the hydraulic hose D 'through the hydraulic downward circulation port 21 "'. Join the hydraulic pressure supplied through the booster device 20 to ride the hydraulic hose (D) of the cylinder (7) As the flow into the room interior is operated to retract the piston 6.

Accordingly, since the inlet and outlet 23b of the four-way valve 23 is connected to the open state by being pushed into the rear inner side of the cylinder 7, it is discharged through the hose b, so that the retraction operation of the piston 6 is prevented. It is performed smoothly, such a retraction operation of the piston (6) proceeds at a high speed by the hydraulic pressure flowing out by the pneumatic pressure pressed into the oil tank (19), the retraction operation pressure of the piston (6) at this time is the tire (T) Since the pressure is such that the side wall of the pressure cannot be compressed, the hydraulic supply operation is performed only until the wheel itself is brought into close contact with the annular pressure port 5 side, and the subsequent operation is performed by the booster device 20. The hydraulic pressure sucked by 19 is supplied to the inside of the front of the cylinder 7 as a much increased pressure. The booster device 20 of the present invention provides a compressed air of the compressor during the pressure operation of the booster valve 24. 20) By entering the pneumatic inlet (20 ') of the hydraulic pumping piston installed therein to reveal the hydraulic pumping operation, the hydraulic pressure by the hydraulic pumping operation of the booster device 20 of this operating configuration to increase the hydraulic pressure strongly As an accompanying state, it is discharged to the hydraulic downward circulation port 20 "'.

Here, the role of the booster device 20 is only responsible for discharging the hydraulic pressure in a high pressure state by pneumatic pressure, and its specific operation configuration and action will be omitted.

Therefore, when the booster device 20 is operated by pressing operation of the booster valve 24 as shown in the example of FIG. 7, the oil pressure flowing into the hydraulic outlet 20 ′ 'is lower than the oil pressure flowing into the hydraulic circulation valve device 21. The strong hydraulic pressure ensures that the ball valve 44 closes the inflow passage of the hydraulic side circulation port 21 "to prevent the leakage of the increased hydraulic pressure, so that the enhanced hydraulic pressure of the cylinder 7 The retraction operation of the piston 6 becomes a more powerful state as the whole amount flows into the front interior.

As described above, the tire T of the wheel, which is fixed to the distal end of the piston 6 which has been retracted by the hydraulic supply action by pneumatic pressure, slightly presses the distal end of the stopping plate 10 for inserting the annular pressure port 5 into the tire ( When the side wall of T) comes into contact with the stopping stone piece 8, no further retraction operation is performed. Therefore, the booster valve 24 is pressurized at the same time to strongly increase the hydraulic pressure to the cylinder 7. By supplying, pressure is applied to the side wall of the tire T as the insertion blocking plate 10 and the blocking stone piece 8, and the tip of the insertion blocking plate 10 at this time is the wheel W as shown in FIG. Since it is installed in a state wider than the outer diameter of the binding ring (R) that is bound to one side of the coupling ring, the side wall of the binding ring (R) is contacted first and the sidewall is pushed while pushing the sidewall according to the strong retraction operation pressure of the piston (6). Digging into the back of the ring (R) and into the outer circumferential surface of the binding ring (R) It comes in contact with the state (refer to the virtual line of FIG. 4).

Therefore, the insertion stop plate 10 actually pushes the outer circumference of the inner surface T 'of the tire T from the side, thereby preventing damage to the inner surface caused by pushing the upper portion of the inner surface of the tire T as in the prior art. In addition, since the reinforcing iron core T ″ is internally formed on the inner circumferential surface of the tire T, the configuration for pushing the position of the reinforcing iron core T ″ prevents damage of the tire T, thereby binding the binding ring ( The relaxation action with R) can be performed more reliably, and the retraction of the tire T is continued by the retraction operation of the piston 6, which continues with the insertion stopper plate 10 which has dug into the back side of the binding ring R. The pressing action of the tire T sidewall proceeds smoothly by the stopper piece 8 that pushes the inner circumferential surface and pushes the tire T sidewall, and under the condition that the retraction operation of the piston 6 is completed. As shown in the example of FIG. 5, one side wall of the tire T At this time, the internal contact surface of the crushed one side wall is completely displaced from the normal contact position, and the internal contact surface is loosened with the outer peripheral surface of the wheel (W). The wheel W and the tire T can be separated.

After the one side wall of the tire (T) is compressed and separated as described above, the tire (T) is properly spaced from the annular pressure port (5) by operating the piston (6). ) The forward operation is performed as the left rotation operation of the four-way valve 23 described above, and after completion of the forward operation, the circular binding plate 14 is dismantled, and then the handle 30 is rotated counterclockwise to move the lifting plate. After lowering the sieve 25, the tire T is lowered to the floor, the wheels are reversed, the wheels are placed on the rollers 26 and 26 ′, and the handle 30 is moved upward to move the tactics. As in one method, when the wheel is attached to the front end of the advanced piston (6), the axle (W ') axis of the wheel (W), which has not been subjected to the electric separation operation, is in a state facing the annular pressure port (5). will be.

As described above, the separation operation of the other inner contact surface of the tire T, which is attached to the outer circumferential surface of the wheel W enlargement portion W ″, which has not been subjected to the separation operation process as described above, also retracts the piston 6 by hydraulic pressure. And then pressurized to the annular pressure port (5), and then inserted into the annular pressure port (5) by retracting the piston (6) gradually and powerfully with the increased hydraulic pressure by the hydraulic pumping operation of the booster device (10). The blocking plate 10 is inserted into the rear side of the enlarged portion W ″, and the lower inner end surface of the tire T is underneath, thus pushing the other side wall of the tire T. As described above, the side wall portion is separated from the outer peripheral surface of the enlarged portion W ″ side of the wheel W without difficulty.

As described above, since both inner contact surfaces of the compressed tire T on both side walls are loose with the outer circumferential surface of the wheel W, the operator disassembles the tire T from the separator of the present invention and uses the wheel W with little force. It can simply be separated and then a predetermined tube puncture repair can be performed.

The present invention as described above puts the flat wheel on the roller of the lifting plate body installed in the lower frame of the separator and moves upward to bind the wheel to the piston end, and then moves the piston at high speed as hydraulic pressure so that the side wall of the tire is an annular pressure port. After the contactor is in operation, the booster device is operated to retract the piston as enhanced hydraulic pressure, and the side wall of the tire is pushed to the stopper piece of the annular pressure port, the stopper piece for insertion, and the stopper plate for insertion, and the inner surface of the sidewall part is enlarged. Alternatively, the inner ring of the tire may be detached from the outer circumferential surface of the removing ring shaft, but the insertion stop plate is configured to push the end of the inner contact surface without damaging the inner contact surface as in a conventional device which exerts the pressure while applying excessive pressing pressure to the inner contact surface of the tire. Slip the surface from the outer circumference of the wheel to make it loose. By slipping on the outer circumferential surface to be in a loose state, there is an effect that can significantly extend the life of the tire, and in particular, the present invention can be miniaturized the separator itself by pulling the tire to separate it by the operation to retract the piston. It is a very practical design that can be provided to the consumer at a lower price than the device.
