Description

Technical Field

[0001] The utility model relates to the field of storage equipment, in particular to a supporting fork device. Background Art

[0002] The plate fork device (also called a supporting fork device or a fork tooth device) in the Chinese utility model patent CN114633254A "An automatic disassembly and assembly device for a container lock button and a disassembly and assembly system composed thereof" cannot cover the entire warehouse area due to the limitation of the design space, which easily wastes the storage space. Usually, the plate fork is installed on a carrier mechanism (usually a trolley) with a multi-stage lifting mechanism. The multi-stage lifting mechanism has a minimum installation height. In addition, due to the height limitation of the equipment, when the plate fork is installed at the bottom of the multi-stage lifting mechanism, the top space will be wasted, and when it is installed at the top, the bottom space will be wasted. Therefore, a structure is needed to solve this problem and ensure the utilization of space. In addition, when used in port storage equipment, the working environment is relatively harsh, with high temperature, high humidity and high salt fog. The supporting fork device needs to be sun-resistant, moisture-resistant, rust-resistant, etc. Utility Model Content

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] See also Figure 1-3 , the figure shows that the fork device of the utility model includes:

[0032] A pair of fork tines 1, each with an opening along its length at the right end. A fixed shaft 2 matching the opening is provided at the work site. The fork tines 1 are inserted into the fixed shaft 2 by the movement of the trolley to restrict their movement in the height direction. In this embodiment, the fixed shaft 2 includes two sets, one at a high position and the other at a low position.

[0033] A longitudinally arranged supporting connecting member 3, which is in the shape of an elongated strip, has its right side fixedly connected to the left end of a pair of fork tines 1, and its left side can be slidably installed up and down on the left side of a trolley (not shown in the figure), and the front and rear ends of the supporting connecting member 3 protrude from the front and rear sides of the trolley, and a working slider 3-1 and a locking slider 3-2 are provided on the left side of the front end portion of the supporting connecting member 3, and the working slider 3-1 and the locking slider 3-2 are provided on the upper and lower sides and the left sides are both inclined surfaces inclined toward the lower left direction; further, the left ends of the pair of fork tines 1 are fork tine connecting parts 1-1 of an integrated structure and are fixedly connected to the supporting connecting member 3 through the fork tine connecting parts 1-1; further, the supporting connecting member 3 is a split structure provided at the front and rear;

[0034] In this embodiment, the trolley is provided with a lifting mechanism (not shown in the figure), and the supporting connecting member 3 can be slidably mounted on a lifting component (not shown in the figure) at the top of the lifting mechanism. Furthermore, it also includes a mounting seat 4, which is fixedly mounted on the trolley or the lifting component at the top of the trolley's lifting mechanism through the mounting seat 4;

[0035] An adjusting mechanism 5 is installed on the upper part of the front side of the trolley on the same side as the working slide 3-1. The adjusting mechanism 5 includes:

[0036] A bottom plate 5-1,

[0037] A slide rail 5-2 fixedly mounted laterally on the base plate 5-1;

[0038] A support block 5-3 is mounted on the slide rail 5-2 so as to slide left and right. The right side of the support block 5-3 is an inclined surface structure that matches the left side of the working slider 3-1 and a locking slider 3-2. The support block 5-3 can move rightward to the bottom of the working slider 3-1 and lift the working slider 3-1, thereby enabling the support block 5-3 to lift the fork tine 1;

[0039] A push plate 5-4 is provided on the top of the support block 5-3 and is not located at the left or right end thereof; further, the push plate 5-4 is a vertically arranged plate; further, the push plate 5-4 and the support block 5-3 are an integral structure;

[0040] A spring rod 5-6 is placed horizontally and fixedly mounted on the trolley at its left end via a first fixing block 5-5. A push plate 5-4 is provided with an opening and slidably passes through the spring rod 5-6. A spring 5-7 is fitted on the spring rod 5-6 between the first fixing block 5-5 and the push plate 5-4. When the support block 5-3 is used to support the bottom of the working slider 3-1, the spring 5-7 presses against the push plate 5-4.

[0041] A ball lock card 5-8 fixedly connected to the trolley, and a clamping piece 5-9 matching the ball lock card 5-8 is provided at the left end of the support block 5-3. When the trolley causes the support block 5-3 to move downward, its left side slides along the left side of the locking slider 3-2, forcing it to slide leftward along the slide rail 5-2, and the clamping piece 5-9 can be used to lock it. At this time, the spring 5-7 is in a compressed state; and

[0042] A first reset slider 5-10 is provided on the front side of the support block 5-3, and the left side of the first reset slider 5-10 is an inclined surface structure inclined to the lower left. A second reset slider 5-11 is provided at the work site and the installation height is higher than the first reset slider 5-10. The right side of the second reset slider 5-11 is provided with an inclined surface structure matching the left side of the first reset slider 5-10. When the support block 5-3 is locked to the bead lock card 5-8 by the clamping member 5-9, the movement of the trolley causes the support block 5-3 to move upward. During the movement, the clamping member 5-9 of the support block 5-3 is forced to disengage from the bead lock card 5-8 and unlock through the action of the matching inclined surfaces of the first reset slider 5-10 and the second reset slider 5-11. At this time, the spring 5-7 pushes the push plate 5-4 and thereby drives the support block 5-3 to reset.

[0043] Furthermore, the left end of the spring rod 5-6 is connected to a hydraulic buffer 6, and the hydraulic buffer 6 is fixedly mounted on the trolley through a second fixing block 6-1.

[0044] The process of adjusting the tine 1 from the bottom of the mounting base 4 (not shown in the trolley in this embodiment) to the top of the trolley is as follows:

[0045] (1) The trolley moves to insert the opening at the right end of the fork tine 1 into the corresponding fixed shaft 2;

[0046] (2) The trolley moves the mounting seat 4 downward. At this time, due to the restriction of the fixed shaft 2, the fork tine 1 moves upward relative to the mounting seat 4;

[0047] (3) The right end of the support block 5-3 first contacts the working slider 3-1 and forces the support block 5-3 to slide to the left through the inclined surface and compresses the spring 5-7. The mounting seat 4 continues to descend until the support block 5-3 is separated from the working slider 3-1;

[0048] (4) The spring 5-7 pushes the push plate 5-4 so that the support block 5-3 returns to the right and supports the working slide 3-1, thus completing the position adjustment of the fork teeth 1.

[0049] The process of adjusting the fork tine 1 from the top of the mounting base 4 (where the support block 5-3 supports the working slide 3-1) to the bottom of the trolley is as follows:

[0050] (1) The trolley moves to insert the opening at the right end of the fork tine 1 into the corresponding fixed shaft 2;

[0051] (2) The trolley moves the mounting seat 4 downward. At this time, due to the restriction of the fixed shaft 2, the fork tine 1 moves upward relative to the mounting seat 4;

[0052] (3) The left end of the support block 5-3 contacts the locking slider 3-2 and forces the support block 5-3 to slide to the left through the inclined surface and compresses the spring 5-7. The mounting seat 4 continues to descend until the clamp 5-9 is locked into the ball lock 5-8;

[0053] (4) The trolley moves the mounting seat 4 upward, and the fork tine 1 moves upward relative to the mounting seat 4. When the support block 5-3 is higher than the working slider 3-1, the first reset slider 5-10 begins to contact the second reset slider 5-11 and uses the contacting inclined surfaces to force the clamping member 5-9 to disengage the bead lock clamp 5-8 and release the lock. The spring 5-7 pushes the push plate 5-4 and then drives the support block 5-3 to reset.

[0054] (5) The trolley moves the mounting seat 4 upward until the supporting connector 3 and the fork tine 1 slide to the bottom of the mounting seat 4.

[0055] The fork support device of the utility model can adjust the installation position of the fork teeth 1, ensure the utilization of space, adapt to harsh working environments, use a fully mechanical structure, and have the effect of resisting high temperature, high humidity and high salt spray. At the same time, in order to save costs and increase the reliability of the mechanism, no power mechanism can be added, and only the original power system can be borrowed.

[0056] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and should be defined by the claims.
