Description

  The present invention relates to a fall prevention device for preventing a cargo handling worker from falling from a cargo bed during cargo handling work on a truck bed.

  According to Articles 518 to 521 of the Industrial Safety Regulations, if there is a risk of workers falling due to a fall at a height of 2m or more, it is difficult to provide a work floor, It is said that measures must be taken to prevent workers' dangers due to the fall, such as having workers use safety belts. The truck bed is approximately 1m, but depending on the load, work may be performed standing on it. In that case, work at a height of 2m or more from the ground may occur, and of course the danger due to a crash is predicted. However, as a matter of fact, sufficient safety measures have not been taken for these operations.

  Therefore, in a truck provided with a rotating shaft on the upper end side of the eaves forming the side wall of the loading platform, and provided with a framed seat that can be rotated in the vertical direction by this rotating shaft, the truck is attached to the framed seat, A fall-preventing tool for preventing a fall from a truck bed is disclosed (see Patent Document 1). In addition, a pair of struts are erected along the side of the truck on the ground on the side of the truck. There is also a fall prevention facility for safety (see Patent Document 2).

  Utility Model Registration No. 3177898   JP 11-291863 A

  However, in the case of the above-mentioned Patent Document 1, it is possible to prevent a fall by using a frame-equipped sheet that is rotatably installed on a ridge that is erected on the side of the track. It is not available for tracks that are not. Moreover, the fall prevention equipment described in Patent Document 2 needs to install a pair of support columns on the ground on the side of the truck, and may not be installed depending on the work place.

  Therefore, the present invention has been made in view of the above-described conventional problems, and a fall prevention device capable of ensuring safety with a simple structure is provided as a risk prevention measure in accordance with the occupational safety regulations during cargo handling work on a truck bed. The purpose is to provide.

  In order to solve the above-described problems, in the present invention, a socket member attached to a predetermined position on the side of the front torii portion of the truck bed, a pillar member that can be inserted into the socket member, and the truck bed A hook member attached to the upper part of the round steel member and the pillar member, which is composed of a U-shaped socket member attached to each of the rear side surfaces and a pillar member having a plate that can be inserted into the socket member. The master rope is stretched over a detachable hook.

  With this configuration, it is possible to prevent the operator from falling by hooking the safety rope on the master rope in the truck bed, and to perform safe cargo handling work on the truck bed.

  In addition, the column member inserted into the position on both rear side surfaces of the truck bed is further provided with a length adjusting sub-column member.

  Since it is configured in this manner, it is possible to perform a safe work on the truck bed according to the height of the luggage loaded on the truck bed by adjusting the length of the sub pillar member.

  The present invention is configured as described above, and dramatically improves the safety of cargo handling workers by taking risk prevention measures in accordance with occupational safety and health regulations without reducing work efficiency in truck operation. Can do.

  In addition, work efficiency can be improved by reliably performing safety management in truck unloading work at construction and civil engineering sites.

It is a figure showing a fall prevention device in one form for carrying out the present invention. It is a figure which shows the use condition of the fall prevention apparatus of this invention. It is a figure explaining the back pillar member of the present invention. It is a figure explaining the front pillar member of this invention.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Needless to say, the present invention is not limited to the present embodiment.

  As shown in FIG. 1, the fall prevention device 1 of the present invention includes a pair of front pillar members 3 attached to a torii member 2 provided on the front side of a vehicle such as a truck, and both side surfaces on the rear side of the vehicle. It is generally composed of a pair of rear column members 4 to be mounted and a master rope 6 stretched over the front column members 3 and the rear column members 4 via hooks 5. In this configuration, the worker performs a cargo handling operation by connecting a safety belt (not shown) to the master rope 6.

  FIG. 2 shows a working state in which the fall prevention device 1 having the above-described configuration is used, and the safety belt 9 attached to the belt of the worker 8 is connected to the master rope 6 via the detachable hook 10. . In addition, by securing a work space with the floor 11 using the eaves erected on both sides of the truck bed 7, the worker 8 can work safely without falling on the truck bed 7. Is possible.

  3 and 4 are explanatory diagrams of the column member, respectively. FIG. 3 shows the rear column member 4, and FIG. 4 shows the front column member.

As shown in the figure, the front column member 3 used in the present invention is made of a cylindrical or prismatic steel material, and is attached to the upper side surface of the torii member 2 at the front of the truck bed 7.
Can be inserted, and the master rope can be stretched around the rear column member 4 to be described later by the hook member 5 provided on the upper portion. On the other hand, the rear column member 4 includes a main column member 13 made of a cylindrical or prismatic steel material and a sub column member 14 that can be inserted into the main column member, and an insertion length adjusting member (not shown). ) To enable height adjustment. A polygon plate 16 to be mounted on a socket member 15 to be described later is attached to the lower portion of the main pillar member 13, and is attached to the side surface of the truck bed 7 by welding so as to be detachable from the U-shaped socket member 15. Yes.

  Moreover, the socket member 12 is comprised from the angle 17 which consists of steel materials, and the hollow cylinder member 18, and enables it to insert the front pillar member 3 mentioned above.

  An example of the use of the fall prevention device 1 configured as described above will be described. First, in the truck bed 7, an operator first installs a floor 11 using a kite, and then a pair of torii members 2 in front of the truck. The front pillar members 3 are respectively installed. At this time, the socket members 12 are respectively attached to the upper part of the torii member 2, and the operation is completed only by inserting the front pillar member 3. Next, the rear column member 4 is attached to the socket members 16 on both sides of the rear side of the truck bed 7 and the length of the sub column member 14 is adjusted to complete the installation of the rear column member 4.

  And the installation of the fall prevention apparatus 1 is complete | finished by stretching the master rope 6 to the hook members 5 and 5 provided in the upper part of the front pillar member 3 and the back pillar member 4 in the front-back direction.

  When using the fall prevention device having the above-described configuration, the cargo handling worker connects the safety belt 9 connected to the belt to the master rope 6 movably by the detachable hook 10.

  The fall prevention device according to the present invention has been described as a device mainly used for work on a truck bed, but may be applied to various other purposes.
