  However, in the prior art, in addition to the work of replacing the hub nut and the long nut member with respect to all the plurality of hub bolts in attaching the vehicle lifting tool to the wheel, the plate member with respect to the vehicle outer end of each long nut member is provided. Fixing work with fixing screws is required, and it takes time and labor to mount the lifting device for the vehicle. Moreover, when the vehicle lifting tool is removed, the same man-hours and time as those at the time of attachment are required, and the attaching / detaching operation of the vehicle lifting tool becomes very troublesome.

  In addition, since the number of hub bolts and the like differ depending on the vehicle type, it is necessary to prepare a long nut member and a plate member corresponding to the number of hub bolts, which increases the cost because of the number of parts. It becomes a factor.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a vehicle lifting tool capable of reducing the number of parts, reducing the cost, and performing the attaching / detaching operation with respect to the wheel very easily. It is to provide.

  In order to achieve the above object, in the present invention, as a vehicle lifting tool, it is screwed instead of a hub nut that is screwed to a single hub bolt among a plurality of hub bolts that attach a vehicle wheel to an axle hub, A tubular body having a hub bolt extension extending outwardly of the vehicle and a winding portion inserted from the vehicle outer side onto the outer peripheral surface of the hub bolt extension and capable of winding the cable-like body of the crane device at the vehicle outer end. A projecting piece integrally projecting radially outward from the outer peripheral surface of the cylindrical body and having a contact piece abutting against the wheel and the tire at an inner side end of the vehicle, and a vehicle of the hub bolt extension body And a restraining member attached to the outer end portion and restraining the cylindrical body from the vehicle outer end side.

  Further, it is preferable that the abutting piece is supported with respect to the protruding piece so as to be able to advance and retract outward in the radial direction of the cylindrical body in accordance with the diameter of the wheel and the tire.

  The contact piece is preferably provided with an elastic material that makes the contact piece elastically contact the wheel and the tire.

  Moreover, it is preferable that the restraining member is provided with a holding part that holds the cord-like body wound around the winding part from the outside of the winding part.

  Furthermore, it is preferable that the projecting piece is provided with a guide portion that guides the cord-like body that is wound around the winding portion and extends upward so as to extend upward at a position spaced outward from the vehicle.

  In short, in short, the hub bolt extension body is screwed instead of the hub nut screwed to the single hub bolt, and the projecting piece abutting piece projecting radially outward from the outer peripheral surface of the cylindrical body, The vehicle lifting tool is attached to the wheel by restraining the cylindrical body from the vehicle outer end side with the restraining member in a state of being in contact with the wheel and the tire. For this reason, when attaching the vehicle lifting tool to the wheel, the replacement work of the hub nut and the long nut member for all the plurality of hub bolts and the fixing work of the plate member to the vehicle outer end of each long nut member by the fixing screw are performed. It becomes unnecessary, and it is only necessary to attach the vehicle lifting tool to the single hub bolt. As a result, the number of man-hours for attaching the vehicle lifting tool is greatly reduced, and the time is greatly reduced.When removing the vehicle lifting tool, the man-hours and time are greatly reduced as in the case of attachment. Thus, the vehicle lifting tool can be attached and detached very easily.

  Furthermore, since the vehicle lifting tool can be attached only to a single hub bolt regardless of the number of hub bolts, it is not necessary to prepare a plate member according to the number of hub bolts separately. Costs can be reduced by reducing the number of parts.

  In addition, when the rope-like body of the crane device is wound around the winding portion of the outer end portion of the cylinder body and lifted, a force pressing the contact piece against the wheel and the tire acts on the projecting piece. For this reason, a force to move away from the vehicle body acts on the cable-like body, and the distance to the cable-like body on the outer side of the vehicle body is sufficient due to the extension amount of the hub bolt extension to the vehicle outer side. It is ensured and damage to the vehicle body due to contact with the cord-like body can be suppressed.

  In addition, the abutment piece is supported with respect to the projecting piece so as to be movable forward and backward in the radial direction of the cylinder according to the diameter of the wheel and the tire, so that the abutment piece can be reliably secured to the wheel and the tire according to the diameter. It can be made to contact.

  Further, by providing the contact piece with an elastic material, the contact piece can be elastically contacted with the wheel and the tire, and damage to the wheel and the tire due to the contact of the contact piece can be surely prevented. .

  In addition, by providing the restraining member with a holding part that holds the cord-like body wound around the winding part from the outside of the winding part, the holding-like part can surely shake the cord-like body during lifting. It is possible to prevent the vehicle body from being damaged due to contact with the cord-like body.

Furthermore, by providing the projecting piece with a guide portion that guides the cord-like body wound around the winding portion so as to extend upward at a position spaced outward from the vehicle, the projecting piece is provided above the winding portion. The extending cord-like body is guided at a separated position on the outer side of the vehicle, and the vehicle body can be reliably prevented from being damaged by the contact with the cord-like body.

The vehicle lifting tool 1 is formed of a steel material. A5 is a tire mounted on the wheel A1.

  The hub bolt extension body 2 is formed in a cylindrical shape, and an internal thread portion 21 is formed on the inner peripheral surface thereof, and an external thread portion 22 is formed on the outer peripheral surface thereof. The hub bolt extension body 2 has a vehicle inner end portion of the female screw portion 21 with respect to the single hub bolt A4 instead of a hub nut (not shown) screwed to the single hub bolt A4 when the vehicle lifting tool 1 is attached. It is screwed and extends outward of the vehicle. A7 is a hub nut screwed to the other hub bolt A4.

  The cylindrical body 3 is formed in a substantially cylindrical shape, and the inner peripheral surface 30 is inserted in a loosely fitted state with respect to the outer peripheral surface of the hub bolt extension body 2 so as to be movable in the axial direction of the hub bolt extension body 2. In addition, a flange 31 is integrally provided at the vehicle outer end of the cylindrical body 3. Furthermore, the winding part 32 which can wind the wire W as a cable-like body of the crane apparatus which is not shown in figure is provided in the vehicle outer side edge part (vehicle inner side rather than the collar part 31) of the cylinder 3. As shown in FIG. Only one turn of the tip of the wire W is wound around the winding portion 32. The cord-like body is not limited to the wire W, and may be a cord-like body such as a chain or a rope.

  The projecting piece 4 is integrally formed in a substantially rectangular plate shape radially outward from a vehicle inner end to a vehicle outer end adjacent to the winding portion 32 at a single circumferential position of the cylindrical body 3. Is projected. A contact piece 41 that is opposed to the wheel A1 and the tire A5 is integrally provided at the vehicle inner end of the protruding piece 4. The vehicle inner side surface of the contact piece 41 is a contact surface 42 that contacts the wheel A1 and the tire A5. In this case, the protruding piece 4 is formed in a substantially T-shaped cross section together with the abutting piece 41.

  The restraining member 5 is formed in a hexagonal nut shape, and has an internal thread portion 51 on the inner peripheral surface that is screwed into the external thread portion 22 of the hub bolt extension 2. Then, the restraining member 5 is configured such that the female threaded portion 51 is connected to the male threaded portion 22 of the hub bolt extension 2 in the state where the abutting surface 42 of the abutting piece 41 is in contact with the wheel A1 and the tire A5. It is restrained by tightening from the outer end side. Further, the restraining member 5 is provided with a pair of holding portions 52 that hold the wire W wound around the winding portion 32 from the outside of the winding portion 32. Each holding part 52 is formed of a rod-like body whose base end is rotatably supported around an axis orthogonal to the axis of the hub bolt extension 2 at a position 180 degrees out of phase on the outer peripheral surface of the restraining member 5. Each of the holding portions 52 is supported by the base end of each of the holding portions 52 when the wire W is rotated from the outside of the winding portion 32 to the holding position (position shown in FIG. 1). Inadvertent rotation from the holding position is restricted. In this case, the restraining member 5 rotates substantially horizontally around the axis to the holding position in the state where the contact surface 42 of the contact piece 41 is in contact with the wheel A1 and the tire A5. Thus, the wire W is advanced from the front-rear direction of the winding portion 32 to a position where it can be held, and is pressed against the vehicle outer end of the cylindrical body 3.

  Further, the projecting piece 4 is provided with a guide portion 43 that guides the wire W that is wound around the winding portion 32 and extends upward so as to extend upward at a position spaced outward from the vehicle. The guide portion 43 has a pair of projecting pieces 44 projecting from one of the front and rear surfaces of the projecting piece 4 with the vehicle lifting tool 1 attached, and a base end extending in the vertical direction between the projecting pieces 44. Was it supported to rotate around the axis? And a hook member 45 having a character shape. When the hook member 45 is rotated to an engagement position (position shown in FIG. 1) where the base end is pivotally supported and engaged so as to guide the wire W above the winding portion 32, the hook member 45 is engaged. Inadvertent rotation from the position is restricted.

  Next, a procedure for attaching and detaching the vehicle lifting tool 1 will be described with reference to the drawings.

  First, the case where the vehicle lifting tool 1 is attached to the wheel A1 of the vehicle A derailed from the road will be described. In this case, when attaching the vehicle lifting tool 1, the tubular body 3 is restrained by the restraining member 5 with a margin in a state where the tubular body 3 is inserted in a loosely fitted state on the outer peripheral surface of the hub bolt extension body 2. Shall.

  A hub nut (not shown) is removed from the uppermost single hub bolt A4 among the plurality of hub bolts A4 that attach the wheel A1 to the hub A3, and the removed hub nut is replaced with the single hub bolt A4. The vehicle inner end of the female screw portion 21 of the hub bolt extension body 2 is screwed.

  Next, the cylindrical body 3 is slid toward the vehicle inner side on the outer peripheral surface of the hub bolt extension body 2, and the contact surface 42 of the contact piece 41 of the projecting piece 4 is brought into contact with the wheel A1 and the tire A5. Then, the restraining member 5 screwed to the male threaded portion 22 of the hub bolt extension 2 is tightened inward of the vehicle so that the restraining member 5 is brought into contact with the outer end of the cylinder 3 and the projecting piece 4 is brought into contact. The cylinder 3 is restrained from the vehicle outer end side in a state where the contact surface 42 of the piece 41 is in contact with the wheel A1.

  Thereafter, the wire W of the crane device is wound around the winding portion 32 of the cylindrical body 3, and the pair of holding portions 52 are rotated to the holding positions (positions shown in FIG. W is held. Then, the guide part 43 of the projecting piece 4 is rotated to the engagement position (position shown in FIG. 1) and engaged so as to guide the wire W above the winding part 32. Then, the wire W is pulled up by the crane device, and the wheel A1 of the vehicle A derailed from the road is raised to the road. At this time, as shown in FIG. 2, when the pulling force F of the wire W acts on the winding portion 32 of the cylindrical body 3, a force F2 that pushes down the vehicle inner end (left end in FIG. 2) of the hub bolt extension body 2 downward. A force F1 that presses the upper end of the contact surface 42 of the contact piece 41 against the wheel A1 and the tire A5 acts.

  In this way, the hub bolt extension 2 is screwed in place of the hub nut screwed to the single hub bolt A4, and the cylinder 3 is slid to the inside and outside of the vehicle, so that the abutting piece 41 of the protruding piece 4 In a state where the contact surface 42 is in contact with the wheel A1 and the tire A5, the vehicle lifting tool 1 is attached to the wheel A1 by restraining the tubular body 3 by the restraining member 5 from the vehicle outer end side. For this reason, when attaching the vehicle lifting tool 1 to the wheel A1, it is possible to replace the hub nut and the long nut member with respect to all the plurality of hub bolts A4, or to fix the plate member to the vehicle outer end of each long nut member. No fixing work is required, and only the work of attaching the vehicle lifting tool 1 to the single hub bolt A4 is sufficient.

  On the other hand, when removing the vehicle lifting tool 1 from the wheel A1 of the vehicle A, the guide portion 43 of the projecting piece 4 is rotated from the engagement position to the release position (not shown) (clockwise in FIG. 4). At the same time, the pair of holding portions 52 are rotated to the separation positions (not shown) that separate from the outside of the winding portion 32. Then, the wire W of the crane apparatus is pulled out from the winding part 32 of the cylindrical body 3, and the wire W is wound up by the crane apparatus.

  Thereafter, the restraining member 5 is loosened toward the vehicle outer side of the male screw portion 22 of the hub bolt extension 2 to move the restraining member 5 to the vehicle outer end of the barrel 3, and the cylinder 3 on the outer peripheral surface of the hub bolt extension 2. To the vehicle outer side, the contact surface 42 of the contact piece 41 of the projecting piece 4 is sufficiently separated from the wheel A1 and the tire A5. Then, the screwing of the vehicle inner end of the female screw portion 21 of the hub bolt extension body 2 to the single hub bolt A4 is released, and the hub nut is tightened to the hub bolt A4.

  As a result, the number of man-hours for attaching the vehicle lifting tool 1 is greatly reduced, and the time is greatly reduced. When the vehicle lifting tool 1 is removed, the man-hours and time are greatly reduced as in the case of attachment. Thus, the attachment / detachment work of the vehicle lifting tool 1 can be performed very easily.

  In addition, since the vehicle lifting tool 1 is attached only to a single hub bolt A4 regardless of the number of hub bolts A4, it is not necessary to separately prepare plate members according to the number of hub bolts, etc. Cost reduction can also be achieved by reducing the number of parts of the lifting tool 1.

  Moreover, when the wire W of the crane device is wound around the winding portion 32 of the outer end portion of the cylinder 3 and lifted, the projecting piece 4 has a contact surface of the contact piece 41 against the wheel A1 and the tire A5. The force which presses the upper end part of 42 acts. For this reason, the force which tries to separate from the body A0 of the vehicle A acts on the wire W, and the extension amount of the hub bolt extension 2 to the vehicle outer side, that is, the winding portion 32 of the hub bolt extension 2 at the outer end of the vehicle. Combined with the distance, the distance to the wire W on the outer side of the vehicle body is sufficiently secured, and damage to the body A0 of the vehicle A due to contact with the wire W can be suppressed.

  Further, by providing the restraining member 5 with a holding part 52 that holds the wire W wound around the winding part 32 from the outside of the winding part 32, each of the swinging of the wire W during lifting is held. The portion 52 can be reliably suppressed, and damage to the body A0 of the vehicle A due to contact with the wire W can be prevented.

  Furthermore, the winding portion 32 is provided with a guide portion 43 that guides the wire W that is wound around the winding portion 32 so as to extend upward at a position spaced outward from the vehicle. The wire W extending further upward is guided at a separation position on the outer side of the vehicle, so that the body A0 of the vehicle A due to contact with the wire W can be reliably prevented from being damaged.

In addition, this invention is not limited to the said embodiment, The other various modifications are included. For example, in the above-described embodiment, the contact piece 41 is provided integrally with the protruding piece 4, but as shown in FIGS. 6 and 7, the contact piece 61 has a radius of the wheel A 1 with respect to the protruding piece 6. It may be slidably supported outward in the direction.
Specifically, the protruding piece 6 is constituted by a pair of protruding piece members 60, 60, and the base 62 of the contact piece 61 is slidably accommodated between the protruding piece members 60. Further, the base 62 of the contact piece 61 is provided with a plurality of holes 63, 63,... At equal intervals in the sliding direction between the protruding piece members 60, and each protruding piece. The member 60 is also provided with a single hole 64 (only one is shown in FIG. 7) facing each other. Then, the base 62 of the contact piece 61 is slid between the projecting piece members 60, and the contact piece 61 is located at a position where the contact surface 65 of the contact piece 61 contacts the wheel A1 and the tire A5. The pin member 66 is inserted into one of the hole portions 63 of the base portion 62 and the hole portion 64 of each protruding piece member 60, and the base portion 62 of the contact piece 61 slides between the protruding piece members 60. Positioning is in progress. As a result, the contact piece 61 is moved with respect to the protruding piece 6 in the radial direction outward according to the diameters of the wheel A1 and the tire A5, so that the contact piece 61 can be reliably secured according to the diameters of the wheel A1 and the tire A5. It becomes possible to make it contact | abut.

  Moreover, in the said embodiment, although the contact surface of the contact piece was directly contacted with wheel A1 and tire A5, the sheet-like elastic material may be stuck on the contact surface of the contact piece. . In this case, the contact piece can be elastically contacted with the wheel and the tire to reliably prevent the wheel and the tire from being damaged by the contact of the contact piece.
