Abstract

(57) [Summary] [Purpose] To suppress the swinging of the fork in the cargo handling equipment of a forklift truck and to prevent the generation of noise. [Structure] A forklift truck cargo handling device is provided with a spring member 5 that presses the lower side of the fork 3 toward the finger bar 2 so as to separate the upper side of the fork 3 from the finger bar 2. 3 is supported by a spring member 5 to suppress the swinging of the fork 3 and prevent the generation of noise.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention suppresses the swinging of the fork at the engagement part between the finger bar and the fork. The present invention relates to a cargo handling device for forklift trucks that has been improved so that it can be used more efficiently.

0002

[Conventional technology]

Conventionally, a cargo handling device for a forklift truck has a vehicle body, as shown in FIGS. 5 and 6. A vertically long lift bracket 1 is placed on each of the left and right masts installed in front of the The finger bars 2 are attached to the left and right lift brackets 1 via the lever 4 so that they can move up and down. are constructed above and below, respectively, and a fork 3 is engaged with this finger bar 2. . In this engaging portion, the fork 3 slides left and right along the finger bar 2. It is interlocked so that it can be moved.

0003

[Problem that the idea aims to solve]

Conventional forklift truck cargo handling equipment consists of finger bars and forks. Since the engaging part of the fork is loosely fitted, the fork may swing due to vibrations of the vehicle body while driving. It collides with the finger bar and generates noise. The present invention aims to solve these problems.

0004

[Means to solve the problem]

In order to solve the above problem, the present invention provides a spring member on the fork. The fork is pressed forward or backward of the finger bar. This suppresses vibration and prevents noise generation.

【Example】

Fig. 1 shows a first embodiment of a cargo handling device for a forklift truck according to the present invention. , will be explained using FIG. In a cargo handling device similar to the conventional one, the vertical position of the fork 3 near the upper part of the engagement part with the lower finger bar 2 on the rear surface of the part, so as to protrude left and right. Pins 6 are fixed to each other, and a wire-shaped spring member 5 is attached to each pin 6. is provided. This spring member 5 has a central portion pivoted to a pin 6 and one end The lower finger bar 2 is in elastic contact with the rear surface of the finger bar 2, and the other end is in elastic contact with the rear surface of the vertical part of the fork 3. The pivot point to the pin 6 is used as a fulcrum, and the rear surface of the lower finger bar 2 is By bending and elastically contacting the rear surface of the vertical part of the fork 3, the lower finger The upper side of the fork 3 is pressed forward against the bar 2, and the lower side of the fork 3 is pushed backward. It is designed so that it is pressed against the

[0006] Next, a second embodiment will be explained using FIGS. 3 and 4. Same cargo handling equipment as before at the rear surface of the vertical part of the fork 3, above the engaging part with the lower finger bar 2. A pin 8 is fixed nearby via a block 7, and a plate-shaped plate is placed between the pin 8 and the fork 3. A spring member 5 is supported. This spring member 5 is located below. It is bent in the direction away from arc 3, and then bent in the opposite direction at the end. The end is brought into elastic contact with the rear surface of the lower finger bar 2. Also, the other end has a shaft. 9 is attached in the width direction, and a plate cam 10 is attached to one end of this shaft 9 in the orthogonal direction. This plate cam 10 is supported by a hexagonal bolt head-shaped protrusion 11. . Then, by rotating the protrusion 11 of this plate cam 10 with a spanner or the like, the plate cam 1 0 and separates the other end of the spring member 5, the spring member 5 Using the contact part of the pin 8 as a fulcrum, it comes into elastic contact with the rear surface of the lower finger bar 2. As a result, the upper side of the fork 3 is pressed forward against the lower finger bar 2. , the lower side of the fork 3 is pressed rearward.

[0007] Note that the spring member 5 can easily release the action of pressing the fork 3. After releasing it, move the fork 3 to the left along the finger bar 2 as before. Can be slid to the right.

[0008]

[Effect of the idea] As detailed above, the present invention is applied to a cargo handling device for a forklift truck. A spring member with one end elastically contacting the fork and the other end elastically contacting the finger bar. By providing the fork with a spring member on the finger bar, the fork can be loosened through the spring member. It is highly supported. As a result, when vibration occurs in the vehicle body, it is possible to suppress the rocking of the fork, and the It is possible to prevent collision with the cover and the generation of noise.
