Is set to such a width that the column main body 20 can be erected on the side of the vehicle 2 in a state where the wheel 3 is placed on the tread plate portion 14. However, as the tread plate portion 14, any configuration can be adopted as long as it has a height and strength rigidity with which the wheel 3 can ride. Moreover, the planar shape of the tread portion 14 can be arbitrarily set such as a polygonal shape other than a rectangular shape, a semicircular shape, or a semielliptical shape.

  In order to fix and vertically support the column main body 20 on the tread plate portion 14 of the column base 10, four bolt holes 15 are formed on the left and right portions of the tread plate portion 14 at the substantially central portion in the front-rear direction of the base main body 11. A pair of attachment portions 16 provided in a penetrating manner in the thickness direction are formed corresponding to the corner portions.

  The mounting portion 16 can be provided at an arbitrary position on the tread plate portion 14, but on the side where the wheel 3 is placed on the tread plate portion 14, the mounting portion 16 is lateral to the mounting portion of the wheel 3 in the tread plate portion 14. Will be provided. In the present embodiment, the mounting portion 16 is integrally formed with the tread plate portion 14. However, when the tread plate portion 14 is configured to be thin, the wheel 3 is provided in order to ensure a sufficient length of the bolt hole 15. A plate member having a height that can be ridden is welded and fixed to the tread plate portion 14, or a nut member having a height that can be ridden by the wheel 3 is welded and fixed corresponding to the bolt hole 15. It can also be configured to ensure a sufficient length.

  The protruding portion 13 is formed in a substantially right triangle shape from an inclined wall portion 13a inclined downward in the forward direction and a vertical wall portion 13b extending downward from the rear end portion of the inclined wall portion 13a. The front edge portion of the inclined wall portion 13a is connected to the rear edge portion of the tread plate portion 14, and the base body 11 is formed of a press-formed product obtained by press-forming the protruding portion 13 on a flat metal plate. The lower surface of the protruding portion 13 is opened, and the reinforcing rib 12 is welded and fixed inside the protruding portion 13 with a space in the left-right direction. The protruding portion 13 and the reinforcing rib 12 constitute a wheel stopper 17. The number of the reinforcing ribs 12 can be arbitrarily set, but it is preferable to provide two or more reinforcing ribs 12 so as to close at least the left and right ends of the protruding portion 13. In addition, although the lower surface of the protrusion part 13 was opened, the lower wall part extended ahead from the lower end part of the vertical wall part 13b is provided, and the front edge part of this lower wall part is welded to the front edge part of the inclined wall part 13a. For example, the protruding portion 13 can be formed in a triangular shape in side view having three sides. If comprised in this way, the strength rigidity of the wheel stopper part 17 can be improved. Moreover, although the protrusion part 13 was formed in the right-angled triangle shape in side view, if it is a structure which can prevent reliably rotation of the wheel 3 in a parking state, in the side view, triangle shape other than a right-angled triangle, etc. It can be formed in a trapezoidal shape such as a trapezoidal shape, a rectangular shape such as a rectangle or a square, a semicircular shape or a semielliptical shape.

It is configured to be portable. However, this handle 18 can adopt another shape or can be omitted.

  In the vehicular master rope support device 1, the base body 11 is formed of a press-formed product made of a flat metal plate, so that the manufacturing cost of the support base 10 can be reduced. Alternatively, the tread plate portion 14 and the wheel stopper portion 17 may be configured as separate members, and both may be configured integrally or detachably by bolts or welding.

  The column main body 20 includes an upper pipe 21 and a lower pipe 22 that are telescopically and detachably fitted, a bolt member 23 and a nut member 24 that fix the upper pipe 21 to a desired extension position with respect to the lower pipe 22, A pair of front and rear side eyebolts 25 as a parent fixing portion provided in a plurality of sets at intervals in the vertical direction above the upper pipe 21, an upper eyebolt 26 fixed to the upper end portion of the upper pipe 21, and a lower pipe 22 And a fixing plate 27 provided at the lower end. In addition, the support | pillar main body 20 can also be comprised with one pipe member, and can also be comprised with three or more pipe members fitted so that expansion-contraction is possible.

  The upper pipe 21 and the lower pipe 22 are made of a metal pipe member such as stainless steel or carbon steel having strength and rigidity capable of supporting the weight when the worker W falls. As long as the upper pipe 21 and the lower pipe 22 can be fitted without play, the thickness and outer diameter thereof can be set as appropriate.

  A plurality of pairs of front and rear height adjustment holes 21a are formed at regular intervals in the height direction at the lower portion of the upper pipe 21, and a pair of front and rear connection holes 22a are formed at the upper portion of the lower pipe 22. The height adjustment hole 21a of the desired height of the upper pipe 21 is communicated with the connection hole 22a of 22 and the bolt member 23 is inserted over the connection hole 22a and the height adjustment hole 21a. The upper pipe 21 can be fixed to a desired extension position with respect to the lower pipe 22 by fastening the nut member 24 to the portion.

  In addition, the arrangement | positioning pitch and number of the up-down direction of the height adjustment hole 21a can be arbitrarily set according to the height etc. of the loading platform 4 of the vehicle 2 to apply. Further, the arrangement pitch and the number of the side eyebolts 25 in the vertical direction can be arbitrarily set. Further, the upper eyebolt 26 can be omitted, and the front or rear side eyebolt 25 can also be omitted.

  A metal fixing plate 27 is fixed by welding to the lower end portion of the lower pipe 22, and a portion of the fixing plate 27 that protrudes outward from the lower pipe 22 corresponds to the four bolt holes 15 of the mounting portion 16. Four bolt insertion holes 27a are formed. The lower pipe 22 has a pair of mounting portions 16 by superimposing the fixing plate 27 on the mounting portion 16, inserting bolt members 28 into the bolt insertion holes 27 a, and fastening the bolt members 28 to the bolt holes 15. Are fixed to the column base 10 so that the position can be switched.

  Next, an example of a method for using the vehicular master rope support device 1 will be described. However, it is also possible to install the master rope support device 1 for a vehicle by a procedure other than the usage method described below.

  As shown in FIG. 1, a pair of front and rear vehicle master rope support devices 1 corresponding to the front and rear wheels 3 on the left or right side of the vehicle 2 are installed, The hook F1 provided at both ends of the rope C is hooked, and the master rope C is stretched between the upper parts of the two rope support devices 1 with the hook F1, or the front or rear side of the vehicle 2 on the left or right side. The master rope support device 1 for a vehicle is installed corresponding to the wheel 3, and the master rope C is stretched between the upper portion of the master rope support device 1 for the vehicle and the vehicle body 5. As shown in FIG. 1, when carrying out loading and unloading work, a safety band S connected to the belt B of the worker W is provided with a hook F2 provided at the free end of the safety band S. Therefore, even if the worker W falls from the loading platform 4 by being hooked on the master rope C, the safety of the worker W is ensured.

  More specifically, when the vehicle main rope support device 1 is installed in correspondence with the wheels 3, the support base 10 is first moved to the right or left side of the vehicle 2 on which the main rope C is stretched, and When the vehicle 2 is parked on the hill, the positional relationship between the support base 10 and the wheel 3 is such that the tread plate portion 14 is located on the rear side of the wheel 3 on which the vehicle master rope support device 1 is installed. The support base 10 is installed so that the wheel 3 is closer to the wheel 3 and the side portion protrudes to the side than the vehicle 2. When the vehicle 2 is parked on the downhill, the support base 10 is disposed on the front side of the wheel 3 on which the vehicle master rope support device 1 is installed. The support base 10 is installed so that it is on the side of the wheel 3 and the side portion protrudes to the side of the vehicle 2.

  Next, the column main body 20 is erected and fixed to the attachment portion 16 on the side protruding from the vehicle 2 of the pair of attachment portions 16 by the bolt member 28. And the position of the parent rope support device 1 for vehicles is finely adjusted so that the space | interval of the support | pillar main body 20 and the vehicle body 5 may become as small as possible.

  Next, when parking on the uphill, the vehicle 2 is moved backward until the wheel 3 comes into contact with the wheel stopper 17, the tread plate portion 14 is held between the wheel 3 and the ground G, and the vehicle is parked on the downhill. In this case, the vehicle 2 is moved forward until the wheel 3 comes into contact with the wheel stopper 17, the tread plate portion 14 is sandwiched between the wheel 3 and the ground G, and the master rope support device 1 for the vehicle on the side of the wheel 3. Will be fixedly installed.

  After the vehicle master rope support device 1 is fixedly installed in this way, the extension length of the upper pipe 21 of the column body 20 is adjusted according to the height of the loading platform 4, and the upper pipe 21 is connected to the lower pipe 22 with the bolt member 23. Thus, the main rope C is stretched between the pair of vehicle main rope support devices 1 or between the vehicle main rope support device 1 and the vehicle body 5. When parking and working on a flat ground G having almost no slope, either the above-mentioned method of parking on an uphill or the case of parking on a downhill is adopted. The support device 1 is fixedly installed on the ground G.

  In this vehicular master rope support device 1, similarly to the conventional vehicular master rope support device, loading and unloading are performed in a state where the safety belt S of the worker W is hooked on the stretched master rope C by the hook F <b> 2. By performing such operations, it is possible to ensure the safety of the operator W when the vehicle falls from the loading platform 4. In addition, it is possible to reliably fix the tread plate portion 14 to the ground G by using the weight of the vehicle body, and the backlash of the column main body 20 is significantly less than that of the vehicle main rope support device described in Patent Document 1. Thus, the safety of the worker at the time of falling can be further improved. In addition, since the height H of the wheel stopper 17 provided on the tread 14 is set to a height at which the wheel 3 cannot get over, when the vehicle is loaded on the slope or unloaded, It can prevent rotation and improve work safety. Furthermore, with a simple configuration in which a pair of left and right mounting portions 16 each consisting of four bolt holes 15 are provided, even when the master rope C is stretched on the left side of the vehicle 2 or when the master rope C is stretched on the right side, Whether the wheel stopper 17 is arranged on the front side of the wheel 3 or the wheel stopper 17 is arranged on the rear side of the wheel 3, the number of parts can be increased by changing the mounting position of the column main body 20. The vehicle master rope support device 1 can be easily fixed and installed on the ground G.

  9A and 9B, in place of the fixing plate 27, an inverted U-shaped metal fixture 30 is welded and fixed to the lower end portion of the lower pipe 22, and a wheel stopper portion is provided. It is also possible to fix the fixture 30 on both sides of the bolt 17 with the bolt members 31 and to fix the column main body 20 upright on both sides of the wheel stopper 17.

  Further, as in the vehicle master rope support device 1B shown in FIG. 10, a fixing hook 32 that can be engaged with the upper portion of the side tilt 6 of the vehicle 2 is provided in the middle of the upper pipe 21 in the height direction. It is also a preferred embodiment to be provided so as to be rotatable through the member 33. In this vehicular master rope support device 1, when the vehicular master rope support device 1 is installed corresponding to the wheel 3, the fixing hook 32 is engaged with the upper part of the side tilt 6 of the vehicle 2, thereby Even when a large lateral load is applied to the column main body 20 due to a fall of W or the like, the load can be received by the vehicle body 5 via the fixing hook 32. The problem that the main body 20 falls can be effectively prevented.

  The embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and it goes without saying that the configuration can be changed without departing from the gist of the present invention.
