Description

An eight pulley rack

technical field

The utility model relates to a loading frame of a container crane, in particular to a loading frame with eight pulleys.

Background technique

The upper frame is an important part connecting the spreader and the trolley. The conventional upper frame generally uses an electric eight-rope upper frame. Because the upper frame has eight wire rope connection points and the moving parts are driven by an electric push rod, it is called an electric eight-rope upper frame. The electric eight-rope loading rack is based on the various functions of the ordinary racking, and the horizontal movement function of the spreader and the container is added, so that the container can be freely adjusted within a certain range without the operation of the trolley of the crane. The spatial location provides fast and convenient conditions for drivers to accurately load and unload containers. In addition, the anti-sway function is added to the electric eight-rope loading rack, which effectively prevents the rack from swaying in any direction during the operation process, creating conditions for the driver to load and unload containers smoothly and quickly.

But there is following defective again in above-mentioned electric eight-rope upper shelf simultaneously:

1. Because the anti-sway force of the electric eight-rope upper frame is too large, the wheel of the crane is particularly damaged;

2. The electric push rod pushes the connecting plate to slide on the sliding seat, so the friction reducing block/roller of the connecting plate is particularly damaged.

Detailed ways

The technical scheme of the utility model is further described below in conjunction with the accompanying drawings and embodiments.

Please refer to FIG. 1 to FIG. 8 , the eight-pulley upper frame provided by the utility model includes the upper frame body 100 , the above is part of the prior art, and will not be repeated here. The difference from the prior art is:

Preferably, the upper rack body 100 is provided with a pulley mechanism 1, a push rod translation mechanism 2 and a gear anti-sway mechanism 3, the upper rack body 100 is lifted by the pulley mechanism 1, and the upper rack body 100 and the crane are driven by the push rod translation mechanism 2. The translation of the tool 101 reduces the shaking of the rack body 100 through the gear anti-shake mechanism 3 .

Preferably, the pulley mechanism 1 includes: four sets of pulleys 11 are provided, wherein two sets of pulleys 11 are respectively connected to the upper and lower sides of the upper frame body 100 in the longitudinal direction (ie, the direction of the cart), and the other two sets Pulley 11 is respectively connected on the left and right sides of upper frame body 100 width direction (ie dolly direction). As shown in Fig. 2 and Fig. 3, when the upper frame body 100 is lifted to the highest point, the angle of the wire rope 12 on the pulley 11 is smaller, which generates a larger lateral component force and reduces the shaking of the upper frame body 100 during lifting.

Preferably, the push rod translation mechanism 2 includes: a traverse push rod 51 and a longitudinal push rod 52, the traverse push rod 51 is arranged at the middle position of the upper frame body 100, and the two sides of the traverse push rod 51 are respectively arranged A vertical push rod 52, wherein the thrust used by the lateral push rod 51 is set to 13T to realize the translation of the upper frame body 100 and the spreader 101 in the left and right direction (ie, the running direction of the cart) ± 300mm, and the vertical movement on both sides The push rods 52 all adopt a thrust setting of 6.5T, and when the longitudinal push rods 52 on both sides expand and contract at the same time, they are used to realize the translation of the upper body 100 and the spreader 101 in the front and rear direction (ie, the running direction of the trolley) ±300mm; When the side longitudinal push rods 52 expand and contract in opposite directions, the rotation between the upper frame body 100 and the spreader 101 can be realized.

Preferably, both the lateral push rod 51 and the vertical push rod 52 include: an electric push rod 511, a push rod rotary support 512 and a rotary shaft 513, and the bottom end of the electric push rod 511 is connected to the push rod for rotation through the rotary shaft 513. Encoders are also installed on the support 512 and the electric push rod 511 to realize the judgment of the moving positions of the rack body 100 and the spreader 101 and to control the moving direction of the rack body 100 and the spreader 101 .

Preferably, the gear anti-sway mechanism 3 is provided with two, which are respectively connected to the corresponding pulleys 11 located on the left and right sides of the upper frame body 100 in the width direction. Each gear anti-sway mechanism 3 includes: two sets of phase Engaged anti-sway gear set. Every group of anti-sway gear sets all comprises: connection gear 61,62, and anti-sway gear 63,64 connected with it, connection gear 61,62 is connected with the pulley 11 of corresponding left and right sides, anti-sway gear 63 and Another set of corresponding anti-sway gears 64 is engaged. When the rack body 100 is normally lifted and lowered, the connecting gears 61, 62 rotate together with the correspondingly connected pulleys 11; There is sliding friction between the wire rope 12 and the rope groove of the pulley 11, and the friction force can make the rack body 100 stop shaking quickly.
