Since it is a simple structure assembled to a movable carriage, it is possible to obtain a drum remover for a vehicle that is low in cost and excellent in usability.

For example, the angle adjustment means during use can adjust the angle by about 25 ° as will be described later. Therefore, even a vehicle brake drum whose outer diameter of the trunk portion is different between the front and rear can be easily received horizontally. it can. In other words, when the vehicle brake drum is received by a horizontal member with no inclination from the beginning, the vehicle brake drum has problems such as tilting and impact when contacting the trunk on the short diameter side. It will be resolved.
Moreover, since the drum receiving arm which receives a vehicle brake drum consists of two parallel arm members which can be opened and closed, a vehicle brake drum can be easily rotated in the received state. That is, it is possible to easily check the lower side of the drum or the entire drum by turning it.
Further, since the vehicle brake drum is received in such a manner that it is simply sandwiched between two openable and closable parallel arm members of the drum receiving arm, there is no particular need for fine positioning and the drum can be easily replaced. . In particular, when removing the drum, one end of the vehicle brake drum can be hooked (received) on the drum stopper and pulled out in this state, so that it can be easily removed. That is, good workability can be obtained.

  Further, when both the angle adjusting means of the drum receiving arm and the raising / lowering means are of a manual type, the cost is not greatly increased, and the cost of the entire apparatus can be further reduced.

1 to 4 show an example of a vehicle drum remover according to the present invention.
In the figure, reference numeral 100 denotes an entire vehicle drum remover. In this vehicle drum remover 100, 200 is a drum receiving arm that receives a vehicle brake drum, 300 is a drum stopper that supports one end of the vehicle brake drum, and 400 is a slider clamp (attached to the other end of the vehicle brake drum). Hook), 400a is a long hole shaped clamp hole through which the bolt shaft on the vehicle brake drum side of the slider clamp 400 is passed, 500 is an angle adjusting means for the drum receiving arm 200, and 600 is for adjusting the height of the drum receiving arm 200. The lifting and lowering means 700 is a movable carriage.

  The cart 700 can be used with general existing products, and there are movable tools (moving wheels) 720 such as casters at the four corners on the bottom side of the table base portion (rectangular base plate) 710 serving as a receiving base. -Is attached. Preferably, among these moving tools 720..., The moving tools 720 and 720 (FIGS. 1 and 3) on the rear side of the carriage (the left side in FIG. 1, the opposite side is hereinafter referred to as the front side of the carriage). In this case, it is preferable to use a member incorporating lock members 721 and 721 such as a rotation stop lever. Thereby, since it can stop that a trolley | bogie moves carelessly at the time of a lock | rock, high safety | security is acquired. Further, on the rear side of the table base portion, a handshake stand 730 for movement made of, for example, a pipe material such as a generally inverted U-shape is provided. When the carriage is moving or when a certain stop state is secured, it may be pulled or pressed.

As described above, the drum receiving arm 200 is installed on the table base portion 710 of the carriage 700 via the angle adjusting means 500 and the lifting / lowering means 600.
As shown in FIGS. 1 and 4, the drum receiving arm 200 includes two openable and parallel arm members 210 and 210 such as a hollow steel material. As shown in FIG. It is supported in such a manner that it is sandwiched between recesses formed between the members of the book.

  The two parallel arm members 210 and 210 of the drum receiving arm 200 are cylinders fixed to one end side (rear side of the carriage) of each parallel arm member 210 and 210 with respect to a drum receiving base member 220 such as a hollow steel material. Slide members 230 and 230 such as a mold are slidably fitted and attached. Accordingly, the distance between the parallel arm members 210 and 210 can be adjusted by moving both slide members 230 and 230. That is, the interval between the arm members can be opened and closed. Thereby, it can respond to the magnitude | size (outside diameter) of the vehicle brake drum to handle. The means that can be opened and closed between the parallel arm members is not limited to the above structure as long as it can slide. For example, a guide groove or the like may be provided in the longitudinal direction of the drum receiving base member 220, and a fitting portion with a flange provided on one end side of the parallel arm members 210 and 210 may be slidably fitted and attached.

  On the other hand, near one end of the two parallel arm members 210, 210 of the drum receiving arm 200 (the front side of the carriage), drum stoppers 300, 300 that support one end side of the vehicle brake drum (the inner part when the vehicle is mounted). Is attached. As shown in FIG. 1 and FIG. 2, this consists of a disk-shaped stopper piece. In addition, this is not limited to a disk-shaped thing, A rectangular thing, the plate body and the rod-shaped body of the shape which protrude at least on the upper surface side of the parallel arm members 210 and 210 may be sufficient.

Here, in the case of a vehicle brake drum to be handled, as shown in FIG. 12, the outer diameter of the normal body portion (Da portion in the drawing) is different between the front and the rear, and the weight is unbalanced accordingly. For this reason, the presence of the drum stoppers 300 and 300 has a simple structure, but is extremely important. That is, when the vehicle brake drum is removed from the vehicle, the vehicle brake drum is temporarily received by the drum receiving arm 200, and in this state, one end side of the vehicle brake drum is supported by the drum stoppers 300, 300, and temporarily fixed (temporarily fixed). Because it can be.
At this time, if the right side of the drum receiving arm 200 in FIG. 12 is slightly lowered and tilted, the vehicle brake drum is strongly brought into close contact with the drum stoppers 300 and 300 by its own weight, so that stable support can be obtained. That is, high safety is ensured. In addition, since the inclination at this time can be freely adjusted by the angle adjusting means 500, if the inclination angle is set to an angle that can eliminate the front-rear outer diameter difference in the body portion Da of the vehicle brake drum D, the vehicle brake In a state where the drum D is received, the drum D can be supported horizontally (horizontal with respect to the axis of the parallel arm members 210 and 210).

  Further, the two parallel arm members 210 and 210 of the drum receiving arm 200 include standing plate pieces 410 and 410 that are attached to the other one end side of the vehicle brake drum (a portion that becomes the outside when the vehicle is mounted). Slider clamps 400 and 400 are slidably attached. The shape of the standing plate piece 410 is not particularly limited. For example, as shown in FIG. 2, the standing plate piece 410 may have an arc shape that is open to the outside of the drum receiving arm 200. An engagement hole (not shown) is provided at the base end of the standing plate piece 410, and is slidably fitted to the parallel arm member 210 side through this. Here, the reason why it is slidable is that the thickness of the trunk portion (Da portion in the drawing) varies depending on the size of the vehicle brake drum to be handled, but this is easily accommodated.

Further, the standing plate piece 410 is provided with a clamp hole 400a having a long hole shape through which a bolt shaft (Db portion in FIG. 12) on the vehicle brake drum side is passed.
Specifically, it is an arc-shaped slot corresponding to the arc-shaped member. Here, the arc-shaped elongated hole is formed, for example, as shown on the right side (solid line display portion) in FIG. 13, of the projecting portion Dd at the center of the drum and other adjacent bolts among the many bolt shafts Db. This is because interference with the axis Db can be avoided. Here, as shown on the left side of FIG. 13 (broken line display portion), when the standing plate piece 410 ′ is a linear member and its clamp hole 400a ′ is also a linear slider clamp 400 ′, Interference with the projecting portion Dd and other adjacent bolt shaft Db is unavoidable, and there is a possibility that the intended clamp cannot be performed.
Note that, as described above, the temporary fixing state is realized only by receiving the vehicle brake drum between the two parallel arm members 210 and 210 of the drum receiving arm 200. After passing the bolt shaft Db on the vehicle brake drum side through the clamp hole 400a, an existing fixing nut (the nut removed from the drum, Dc in FIG. 12) is tightened on the bolt shaft Db. At this time, if there are two slider clamps 400, 400, more stable fixation can be obtained, but it is also possible to cope with one.

The drum receiving arm 200 configured as described above incorporates the angle adjusting means 500 between the elevating means 600 for adjusting the height thereof.
The configuration of the angle adjusting unit 500 is not particularly limited, but in this example, it is configured as shown in FIGS. 1, 4, and 8 to 11. That is, one end side (elevating side) of the elevating link member 510 made of a hollow steel material is provided on one end side on the slider clamp side of the parallel arm members 210 and 210 of the drum receiving arm 200, specifically, on the drum receiving base member 220. These are fixed through an L-shaped angle member 520.
On the other hand, the other end side of the lifting / lowering link member 510 is a lift table 610 side that forms the top plate side of the lifting / lowering means 600 and is pivotally attached to a portion closer to the front side of the carriage by a shaft attachment tool 530. The lifting link member 510 is configured to move up and down on the side fixed to the angle member 520 around the shaft attachment 530.

  The drum receiving arm 200, that is, a parallel arm, is opened and closed between a portion where the angle member 520 is fixed to the drum receiving base member 220 side and a portion closer to the rear side of the carriage on the lift table 610 side of the elevating means 600. A pantograph type jack mechanism 550 for adjusting the inclination angle of the members 210 and 210 is assembled.

The pantograph-type jack mechanism 550 can be used with existing products or modified products. In this example, the four link arms 551a... Two assembled pantograph sets 551 and 551 are used.
A rod-like male screw shaft for opening / closing of a jack mechanism is inserted between both connecting portions (built-in female screw members, not shown) of the pantograph sets 551 and 551 facing in the width direction of the carriage. A rotary handle 553 is attached to one end side of the opening / closing male screw shaft 552. By rotating the rotary handle 553, for example, the pantograph sets 551 and 551 in the closed state shown in FIGS. The pantograph sets 551 and 551 in the open state shown in FIG. Of course, if the rotary handle 553 is turned in the opposite direction, the opened pantograph sets 551 and 551 can be closed.

  Both connecting portions of the pantograph sets 551 and 551 facing the carriage in the vertical direction are pivotally attached to the drum receiving base member 220 side and the lift table 610 side of the elevating means 600 via shaft attachments 554 and 554. As shown in FIG. 11, gear mechanisms 555 and 555 including gears fixed to the end portions of the link arms 551a... Are incorporated in the mounting portions of the shaft fasteners 554 and 554, respectively. When the gears between the adjacent pantograph sets 551 and 551 mesh with each other, the diamond shape can be maintained. That is, unless the rotary handle 553 is rotated, the state at that time can be stably maintained.

The angle adjustment by the angle adjustment means 500 configured in this way is not particularly limited, but is about 25 ° with respect to the horizontal reference as shown in FIG.
As described above, the outer diameter of the vehicle brake drum is different between the front and rear sides of the vehicle brake drum, and the weight is also unbalanced. Therefore, when the vehicle brake drum is replaced, it is preferable that the drum receiving arm 200 is slightly inclined. It is easy to do and safe. Therefore, it can be said that the angle adjustment range as described above is sufficient. Here, in particular, if the inclination angle is set to an angle that eliminates the difference between the front and rear outer diameters of the vehicle brake drum body, the vehicle brake drum can be supported substantially horizontally. As a result, for example, when it is received by a horizontal member with no inclination from the beginning, the vehicle brake drum may have problems such as tilting and impact when contacting the trunk on the short diameter side, but this problem has been solved. Is done. That is, high safety is obtained.

  As shown in FIGS. 1 and 5 to 6, the lifting / lowering means 600 for adjusting the height of the drum receiving arm 200 on which the angle adjusting means 500 is mounted has two link arms 621 assembled in an X shape. , 621, two sets of X-type link mechanisms 620, 620 are provided on a table base portion 710 of the carriage. Here, the two sets means that the two sets are provided at two locations near the left and right edges in the front-rear direction of the carriage 700. It is also possible to cope with one set.

  More specifically, the one set of X-type link mechanisms 620 includes a shaft attachment 622, 622 on each end side of the two link arms 621, 621, which is the rear side of the carriage 700. Are attached to the rear side of the table base portion 710 of the carriage 700 and the bottom surface of the rear side of the lift table 610.

  Further, of the two link arms 621 and 621 constituting the pair of X-type link mechanisms 620, each rotating wheel (roller) 623 is provided on each end side (free end side) which is the front side of the carriage 700. , 623 are attached to the bottom surface of the lift table 610 and the upper surface side of the table base portion 710 of the carriage 700. In other words, the two link arms 621 and 621 can be opened and closed with the pivoting portion 624 at the substantially central portion thereof as the center. By opening and closing, the height of the lift table 610 can be adjusted. Although the adjustment height h is not particularly limited, the height from the floor surface of a vehicle maintenance site or the like to the lower end of the vehicle brake drum is about 500 to 800 mm, so that about 500 mm is sufficient.

A hydraulic jack 625 that opens and closes the two sets of X-type link mechanisms 620 and 620 is attached to the bottom surface side of the table base 710 of the carriage 700. The elevating rod 625a is fixed to a connecting member 626 that is passed between the X-type link mechanisms 620 and 620.
As shown in FIG. 5, the foot pedal 627 that raises and lowers the lifting rod 625 a is linked to the plunger portion 628 side of the hydraulic jack 625 so that the foot pedal 627 a can be stepped. Specifically, the pedal rod 627a is pivotally attached to the elevating drive member 628b that is elastically biased by the return spring 628a of the plunger portion 628 while the tip end is pivotally attached to the plunger portion 628 side. It is pivotally attached to the link arm 628c. Reference numeral 628d denotes a guide shaft to which a return spring 628a is attached and which serves as an elevating guide for the elevating drive member 628b.

Accordingly, when the foot pedal 627 is depressed, the lifting drive member 628b is pushed down against the return panel 628a and the hydraulic jack 625 is driven, so that oil is supplied to the built-in cylinder and the lifting rod 625a is lifted. To do. If the stepping is relaxed, the foot pedal 627 is returned by the return panel 628a.
By lifting the lifting rod 625a, the lift table 610 can be easily and quickly raised to the appropriate height.

The lowering of the lifted rod 625a may be performed by opening the jack opening / closing valve (built-in valve, not shown) of the hydraulic jack 625 by the lowering lever 629. As shown in FIGS. 5 and 7, the lowering lever 629 is linked to a drive portion (rotating shaft) 629 d of a jack on / off valve through link rods 629 a, 629 b, and 629 c.
By operating the lowering lever 629 by this linkage mechanism, the link rod 629a is rotated as shown in FIG. 5, and the jack opening / closing valve drive portion 629d is rotated in either direction by the advancement / retraction of the link rod 629b. The jack opening / closing valve is opened, and the lifting rod 625a of the hydraulic jack 625 is lowered. When the drive unit 629d of the jack on / off valve is turned in the reverse direction by the reverse operation, the jack on / off valve is closed. In addition, 629e shown in FIG. 7 is a return panel for automatically returning the lowering lever 629.

  In order to remove the vehicle brake drum from the target vehicle with the vehicle drum remover 100 of the present invention configured as described above, first, the vehicle is advanced below the vehicle brake drum of the target vehicle lifted up. At this time, normally, as shown in FIG. 1, the lifting means 600 is closed and the drum receiving arm 200 is closed. Further, the drum receiving arm 200 may be kept horizontal by the angle adjusting means 500. If the user gets used to it, the approximate height of the vehicle brake drum is estimated, the height of the drum receiving arm 200 is set to a certain level, and the drum receiving arm 200 is moved by the angle adjusting means 500 to the broken line in FIG. As shown in FIG. 4, the right side in the figure may be lowered with a certain degree of inclination.

When the vehicle drum remover 100 is advanced below the vehicle brake drum in this way, the angle adjustment means 500 causes the drum receiving arm 200 to move to an appropriate angle (preferably a vehicle brake having a difference in outer diameter in the trunk portion as described above). The drum receiving arm 200 is lifted by the lifting / lowering means 600 after having an angle at which the drum is horizontally supported.
The two parallel arm members 210 and 210 of the drum receiving arm 200 are attached to and supported on the lower surface side of the vehicle brake drum D whose vehicle has been unlocked, while one end side of the vehicle brake drum D (inside when the vehicle is mounted). The drum stoppers 300 and 300 are applied to the portions) and hooked. In this state, the vehicle brake drum can be easily removed by pulling the vehicle drum remover 100 together with the carriage. As a result, the vehicle brake drum D is supported while being dropped into the drum receiving arm 200 side. Therefore, safe and quick replacement work is ensured. At this time, according to the size of the vehicle brake drum D, the two parallel arm members 210 and 210 may be appropriately slid to adjust the distance therebetween.

  In this state, since the vehicle brake drum D is only placed between the two parallel arm members 210 and 210 of the drum receiving arm 200, the vehicle brake drum can be easily rotated. Therefore, the lower side of the drum or the entire drum can be easily inspected by turning. That is, good usability can be obtained.

  Since the above state is a temporarily fixed state of the vehicle brake drum D, for example, as shown in FIG. 12, the drum receiving arm 200 is made almost horizontal by the angle adjusting means 500 as necessary. In this horizontal state, the standing plate pieces 410 and 410 of the slider clamps 400 and 400 are slid along the parallel arm members 210 and 210 on the other one end side of the vehicle brake drum D (a portion that becomes the outside when the vehicle is mounted). Let them be attached. Of course, the slider clamps 400 and 400 are retracted in advance to the left of the parallel arm members 210 and 210 in FIG.

When the slider clamps 400 and 400 are attached, the bolt shafts Db and Db on the vehicle brake drum side pass through the elongated clamp holes 400a and 400a of the standing plate pieces 410 and 410, so that the bolt shafts Db and Db The existing fixing nuts Dc and Dc are fastened to the protruding portion. Thereby, the main fixing of the vehicle brake drum D is completed.
At this time, as described above, since the standing plate piece 410 and the clamp hole 400a of the slider clamp 400 are an arc-shaped member and an arc-shaped long hole, respectively, the protruding portion Dd at the center of the drum and a number of bolt shafts Db are provided. Among these, the main fixing can be easily performed without interfering with other adjacent bolt shafts Db.

  After that, it is only necessary to transport the carriage 700 to a predetermined maintenance / rentation location with the vehicle brake drum D being permanently fixed. During transportation, the lift table 610 may be lowered to the lowest position by the lifting / lowering means 600, that is, the X-type link mechanisms 620 and 620 may be closed. As a result, the center of gravity of the vehicle brake drum D, which is a load, is lowered, and safe transportation becomes possible.

When the vehicle brake drum D is removed from the vehicle drum remover 100 at the transportation destination, the operation may be performed almost in reverse to the above operation. Further, when the vehicle brake drum D is loaded again on the vehicle vehicle drum remover 100 at this transport destination, the same operation as when the vehicle brake drum D is removed from the vehicle may be performed.
Further, when the vehicle brake drum D is attached to the axle of the vehicle, the operation may be performed almost in reverse to the above-described removal from the vehicle.

  In the above embodiment, the angle adjusting means 500 for the drum receiving arm and the elevating means 600 for adjusting the height are manually operated for the purpose of further cost reduction. The invention is not limited to this. For example, the open / close male screw shaft 552 of the angle adjusting means 500 can be driven by an electric motor such as a motor, or the pantograph jack mechanism 550 can be driven by an electric hydraulic cylinder. Further, even in the lifting and lowering means 600, the manual type hydraulic jack 628 can be replaced by an electric type, or the X-type link mechanism 620 itself can be driven by an electric hydraulic cylinder.
