In the present embodiment, the first power unit 241 is a hydraulic double-stage jack. Next, when the movable element 242 is disposed, in order to enable the first power portion 241 to drive the movable element 242 to move, when the first movable element 240 is disposed, a connection structure for connecting the movable element 242 and a movable end of the first power portion 241 may be further disposed, so that the power of the first power portion 241 is transmitted to the movable element 242 through the connection structure. In addition, in the process of connecting the movable element 242 to the hub, in order to improve the connection stability between the movable element 242 and the hub, the first movable element 240 may further include a connecting member for connecting the movable element 242 to the hub, where the connecting member is used to increase the contact area at the connection position with the movable element 242 and increase the contact area at the connection position with the hub, so as to improve the connection stability. In order to reduce the maintenance requirement, at least two pressing claws 251 can adopt the same structure and are made of high-strength materials, and a rubber protective layer is arranged at the contact part of the pressing claws 251 and the tire.
The working principle of the tire remover 200 is as follows:
the tire detacher 200 includes a base frame 210, a gantry 220, a platen assembly 230, a first movable assembly 240, and a second movable assembly 250. Wherein, the gantry 220 is connected with the underframe 210; the platen assembly 230 is coupled to the chassis 210; the first movable assembly 240 comprises a first power portion 241 and a movable member 242, the first power portion 241 is connected with the gantry 220, and the movable member 242 is in transmission connection with the first power portion 241; the second movable assembly 250 includes at least two pressing claws 251; at least two pressing claws 251 are used for abutting against the outer tire of the tire positioned on the pressing plate assembly 230, and the movable piece 242 is used for connecting with the hub of the tire; first power portion 241 is used to drive moving element 242 and the hub connected to moving element 242 to move relative to the tire casing, so that the tire casing is separated from the hub.
In this arrangement, when the at least two pressing claws 251 abut against the outer tire of the tire located on the pressure plate assembly 230 and the movable element 242 is connected to the hub located on the tire, the movable element 242 and the hub connected to the movable element 242 are driven by the first power portion 241 to move relative to the outer tire, and at this time, the outer tire is kept in contact with the pressure plate assembly 230 by the at least two pressing claws 251, so that the outer tire can move relative to the hub, and the outer tire can be separated from the hub.
Therefore, the tire remover 200 can rapidly separate the outer tire of the tire from the hub through the cooperation of the first movable assembly 240 and the second movable assembly 250, and can reduce the labor intensity of workers in the separation process and improve the operation efficiency.
Further, in the present embodiment, the second movable assembly 250 further includes a pressing beam 252 and a second power portion 253; the body of the second power part 253 is connected with the pressure beam 252, the movable end of the second power part 253 is connected with the portal frame 220, and at least two pressure claws 251 are connected with the pressure beam 252; second power unit 253 the second power unit 253 is used for driving the pressing beam 252 and at least two pressing claws 251 to move towards the direction close to the platen assembly 230 or away from the platen assembly 230. That is, the second power portion 253 can drive the pressing claw 251 to move, so that the pressing claw 251 moves towards the direction close to the pressure plate assembly 230 and abuts against the outer tire of the tire on the pressure plate assembly 230, so that in the process of separating the outer tire from the hub, the outer tire of the tire and the pressure plate assembly 230 can be kept in the abutting state, and the outer tire and the hub can be prevented from moving synchronously when the first power portion 241 drives the moving member 242 and the hub connected with the moving member 242 to separate the hub from the outer tire. The pressing beam 252 can transmit the power of the second power portion 253 to all the pressing claws 251 at the same time, thereby ensuring the stress balance between the contact surfaces of the tire casings contacting the plurality of pressing claws 251.
In the present embodiment, at least two pressing claws 251 are slidably connected to the pressing beam 252 in the axial direction of the pressing beam 252. The interval between the pressing claws 251 is adjusted by sliding the pressing claws 251 relative to the pressing beam 252, so that the pressing claws 251 can be brought into contact with the outer tires of tires having different diameters, and the application range of the tire changer 200 can be increased. In this embodiment, an arrangement manner is adopted in which two pressing claws 251 are provided, and a connection point of the pressing beam 252 and the second power portion 253 is located between the two pressing claws 251.
Further, referring to fig. 1-4, fig. 4 shows the structure of the roller and the slide way in the embodiment of the present invention, in this embodiment, when the second power portion 253 drives the pressing beam 252 to move, in order to enable the pressing claw 251 to abut against the outer tire of the tire when placing the tire, or to cancel the abutting action on the outer tire after the outer tire is separated from the hub to remove the outer tire, it is necessary to guide the pressing beam 252 to move in a direction close to or away from the platen assembly 230. Therefore, the gantry 220 includes a cross bar 221 and two support bars 222, one ends of the two support bars 222 are both connected with the bottom frame 210, and the other ends of the two support bars 222 are respectively connected with two ends of the cross bar 221; the two ends of the pressing beam 252 are movably connected with the two support rods 222, so that the pressing beam 252 is guided to move by the movable connection between the pressing beam 252 and the support rods 222.
In the tire remover 200, the support bar 222 of the gantry 220 is perpendicular to the bottom frame 210 during the tire removing process. That is, the movable connection between the pressing beam 252 and the supporting rod 222 can guide the movement of the pressing beam 252 in a direction perpendicular to the bottom frame 210.
Further, in order to enable the support rod 222 to guide the pressing beam 252 to move in a direction perpendicular to the bottom frame 210 when the pressing beam 252 is movably connected to the support rod 222, the second movable assembly 250 further includes two sliding ways 254, two rollers 255, and two mounting seats 256; the two mounting seats 256 are respectively connected with two ends of the pressing beam 252, the two mounting seats 256 are connected with the two rollers 255 in a one-to-one correspondence manner, the two slide ways 254 are respectively connected with the two support rods 222 and arranged along the extending direction of the support rods 222 in a sliding manner, and the two rollers 255 are matched with the two slide ways 254 in a one-to-one correspondence manner in a rolling manner.
Thus, with the above-described structure, the pressure beam 252 and the support rod 222 can be in rolling engagement with each other, so that the friction coefficient between the pressure beam 252 and the support rod 222 can be reduced, and the movement direction of the pressure beam 252 can be restricted.
In addition, when the mounting seats 256 are provided, in order to ensure that the rollers 255 connected to the pressing beams 252 can be engaged with the sliding ways 254 connected to the supporting rods 222 in a rolling manner, the rollers 255 at both ends of the pressing beams 252 can be ensured to be engaged with the corresponding sliding ways 254 by adjusting the relative positions of the mounting seats 256 on the pressing beams 252. When the rollers 255 and the slide ways 254 are provided, in order to prevent the rollers 255 from being disengaged from the slide ways 254, the contact surfaces of the rollers 255 at the two ends of the pressing beam 252 and the corresponding slide ways 254 are both V-shaped, so as to play roles of preventing falling and limiting.
Further, the second movable assembly 250 further includes at least two springs 257, two ends of the at least two springs 257 are respectively connected to the pressing beam 252 and the cross bar 221, and the at least two springs 257 are distributed on two sides of the second power portion 253. The at least two springs 257 are used for applying an external force to the pressing beam 252, so that the pressing beam 252 has a tendency to move away from the bottom frame 210, and thus when the action of the second power portion 253 is eliminated, the pressing beam 252 can return to a position away from the bottom frame 210 under the action of the at least two springs 257.
Referring to fig. 1 to 5, fig. 5 shows structures of a sliding block and a sliding rail in an embodiment of the present invention, in the embodiment, the bottom chassis 210 includes a frame body 211, two sliding rails 212 and two sliding blocks 213, the two sliding rails 212 are connected to the frame body 211, the two sliding blocks 213 are respectively in sliding fit with the two sliding rails 212, and a fitting surface of the sliding block 213 and the sliding rail 212 is a V shape; the other ends of the two support rods 222 of the gantry 220 are respectively connected with the two ends of the cross bar 221; one ends of the two support rods 222, which are connected with the bottom frame 210, are respectively and rotatably connected with the two sliding blocks 213; the two ends of the support rods 222, which are used for being connected with the bottom frame 210, and the two sliding blocks 213 are respectively provided with a limiting hole 202, and the limiting holes 202 are used for being matched with the limiting pins 203 so as to limit the rotation of the support rods 222 relative to the sliding blocks 213. Through the arrangement mode, the tire remover 200 can be folded, namely when the ends of the two support rods 222, which are used for being connected with the bottom frame 210, and the limiting holes 202 on the two sliding blocks 213 are both disengaged from the limiting pin 203, the effect of limiting the rotation of the support rods 222 relative to the sliding blocks 213 disappears, at the moment, the support rods 222 rotate relative to the sliding blocks 213 through external force, and then the support rods 222 can be driven to rotate towards the direction close to the bottom frame 210, so that the tire remover 200 can be folded.
It should be noted that, when the slide rails 212 are provided, the length of the slide rails 212 is the same as the width or length direction of the bottom chassis 210, so that when the tire remover 200 is folded, the sliders 213 slide relative to the corresponding slide rails 212 through an external force, and the rotation positions of the support rods 222 and the sliders 213 can be relatively located at the ends of the slide rails 212, so that when the tire remover is folded, the folded portal frame 220 is located above the bottom chassis 210, which is beneficial to reducing the volume of the folded tire remover 200.
Further, in this embodiment, four engaging lugs 214 are disposed on the frame body 211, each engaging lug 214 is disposed with an installation hole 215 engaged with the limit pin 203, two sides of the two slide rails 212 are disposed with the engaging lugs 214, and the axes of the installation holes 215 of the four engaging lugs 214 coincide with each other. Namely, the sliding of the sliding block 213 relative to the sliding rail 212 can be limited by the engaging lug 214, that is, the position of the sliding block 213 is limited while the rotation of the supporting rod 222 relative to the sliding block 213 is limited, so as to ensure that the position of the sliding block 213 relative to the sliding block 213 and the angle of the supporting rod 222 relative to the sliding block 213 do not change during the operation of the tire remover 200. It should be noted that, during the operation of the tire remover 200, the engaging lug 214 may be relatively located at the middle position of the sliding rail 212 for improving the stability of the use.
Further, referring to fig. 1-6, fig. 6 shows a structure of a platen assembly in an embodiment of the present invention, in this embodiment, the platen assembly 230 is used to cooperate with a tire to position the tire to be disassembled, so as to facilitate the subsequent abutment of the first movable assembly 240 and the second movable assembly 250 with the tire.
