Abstract
The utility model provides a single cylinder tyre dismantling machine, which comprises a machine frame. The utility model is characterized in that a single cylinder is arranged below the machine frame. The lower end of a piston rod of the cylinder is connected with a pressing device. Commonly, the pressing device is a horizontal pressing rod. Both sides of the pressing rod are respectively provided with a pressing block. The utility model has the advantages of simple structure, convenient operation, and long service life.
Description
Affiliated technical field
The utility model relates to a kind of tyre bead breaker, is specifically related to a kind of single-cylinder machine for dismounting tyre.
Background technology
The tire of self-propelled vehicle uses behind the certain hour because wearing and tearing need replacing.Original tire passes through the artificial unloading, because labour intensity is big, efficient is low, operating personal has just been invented a kind of twin cylinder machine for dismounting tyre, promptly in the both sides of housiung separator a cylinder is set vertically respectively, the piston rod of cylinder is provided with the pressing lever of level down in the lower end of the piston rod of cylinder.When remove a tyre, above tire, be provided with internal diameter greater than wheel hub by trim ring, give the briquetting application of force by cylinder, tire is peeled off on wheel hub, afterwards by manually can easily tire being separated with wheel hub.But above-mentioned twin cylinder machine for dismounting tyre is owing to remain the elasticity of gas and tire in the inner tube of a tyre of tire, in the process of pushing, two cylinder unbalance stress, cylinder are difficult to keep balance, thereby causes the crooked or fracture of piston rod of an end cylinder; Oil cylinder leakage of oil owing to unbalance stress, the service life of demountor is short.
Summary of the invention
The utility model has overcome the complex structure of existing twin cylinder machine for dismounting tyre existence, the shortcoming that lack service life, and a kind of single-cylinder machine for dismounting tyre is provided, and this machine for dismounting tyre is simple in structure, and is easy to operate, long service life.
The utility model discloses a kind of single-cylinder machine for dismounting tyre, described demountor comprises frame, it is characterized in that: single-cylinder is set below frame, and the piston-rod lower end of cylinder connects press device.
In the technique scheme, machine for dismounting tyre adopts single-cylinder, and is simple in structure, and the press device application of force is concentrated, and pressure is big, can satisfy the needs of the tire of the various models of dismounting.Adopt simultaneously single-cylinder avoided application of force inequality between the twin cylinder, should not keep balance, cause the generation of problems such as piston rod bending, fracture, cylinder leakage of oil, the long service life of demountor easily.
Be to realize the purpose of remove a tyre, can various press devices be set in the lower end of the piston rod of cylinder, the preferred version of press device is in the utility model: 1, described press device is for pressing platen.2, described press device is the horizontal pressing bar.
When press device was selected the horizontal pressing bar for use, the both sides of common described pressing lever were provided with briquetting respectively.Briquetting is set increases and push area, make cylinder uniform force application on tire, convenient disassembly.
Push area for ease of size adjustment according to tire, perforate in the common described briquetting, described pressing lever inserts in the described perforate.Perforate in briquetting, briquetting can be slided on pressing lever, therefore can push area according to the size adjustment of tire, to satisfy the needs of the various model tires of dismounting.
For keeping the level of briquetting, common described pressing lever is many prismatics, and described perforate correspondence is set to many prismatics.
In the utility model, single-cylinder is set on machine for dismounting tyre, demountor is simple in structure.Single-cylinder application of force in the remove a tyre process is concentrated, the application of force is big, dismantles more convenient.Single-cylinder uniform force application, the piston rod of cylinder can the bend fractures because the application of force is inhomogeneous, single-cylinder machine for dismounting tyre long service life.
Description of drawings
Fig. 1 is the structural representation of original twin cylinder machine for dismounting tyre.
Fig. 2 is a single-cylinder machine for dismounting tyre specific embodiment structural representation.
Fig. 3 is the STRUCTURE DECOMPOSITION figure that is provided with the pressing lever of briquetting.
The specific embodiment
Fig. 1 is original twin cylinder machine for dismounting tyre, and machine for dismounting tyre comprises frame (not looking out in the view), in the both sides of the crossbeam 1 of frame cylinder 2 and cylinder 3 is set respectively, and the lower end of the piston rod of cylinder 2 and cylinder 3 is provided with pressing lever 4 and pressing lever 5.Because discontinuity in the process of pushing, cylinder 2 and cylinder 3 are difficult to keep balance, cause piston rod bending, the fracture of cylinder 2 and/or cylinder 3 easily, the oil cylinder leakage of oil, and the service life of twin cylinder machine for dismounting tyre is short.
The single-cylinder machine for dismounting tyre comprises frame (not looking out in the view) as shown in Figure 2, and single-cylinder 6 is set below frame, and piston rod 7 lower ends of cylinder 6 are provided with horizontal pressing bar 8.As shown in Figure 3, the cross section of pressing lever 8 is a rectangle, and the both sides of pressing lever 8 can be provided with briquetting 9 and 10 respectively, perforate in the briquetting 9 and 10, and as perforate 11, the corresponding pressing lever 8 of perforate is set to rectangle, in the perforate that pressing lever 8 inserts in the briquetting.
In the above-mentioned specific embodiment 2, because machine for dismounting tyre is a single-cylinder, demountor is simple in structure, and the cylinder application of force is concentrated in unloading process, and pressure is big, and tire dismantling is convenient.Single-cylinder machine for dismounting tyre uniform force application, the piston rod 7 of cylinder can crooked or fractures, and cylinder can leakage of oil.
In the above-mentioned specific embodiment 2, pressing lever 8 can be replaced by by platen or other version.
