Description

Technical Field

[0001] This utility model relates to the field of assistive device technology, specifically to an assistive device for unloading large rolls. Background Technology

[0002] With the continuous development of society, forklifts are increasingly used for loading and unloading goods in factories, warehouses and other locations. However, when encountering large rolls of goods, forklifts cannot lift them from the bottom. It is necessary to use ropes to pass through the inside of the large roll, then tie a knot at the top of the rope or add an auxiliary structure to the rope, and finally use the forklift to insert and lift it. These methods are quite troublesome, and the forklift's insert plate is tilted, so the rope may slip during transportation, which can damage the large roll. At the same time, slippage also poses a certain danger to the workers nearby. Therefore, a large roll unloading assistance device is needed. Utility Model Content

[0003] The purpose of this invention is to provide a large roll unloading assistance device to solve the problems mentioned in the background.

[0004] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution: a large roll unloading assist device, including a positioning block, an insertion hole in the middle of the positioning block, a through hole in the upper middle of the positioning block, and a groove in the inner wall of the through hole. A pressing column is slidably inserted into the through hole, and a limiting ring block is fixedly connected to the middle of the pressing column. The limiting ring block is placed in the groove, and a spring is provided between the lower end face of the limiting ring block and the lower inner wall of the groove. The spring is sleeved on the lower outside of the pressing column. At the same time, a rubber pad is provided at the bottom of the pressing column. A support frame is provided above the positioning block, and a pin is provided above the support frame. An eccentric pressing column is fixedly connected to the middle of the pin, and a toggle rod is provided on the side of the eccentric pressing column.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 As shown, this utility model provides a large roll unloading assistance device, including a positioning block 1, an insertion hole 2 in the middle of the positioning block 1, a through hole 101 in the upper middle of the positioning block 1, and a groove 102 in the middle of the inner wall of the through hole 101. A pressing column 3 is inserted into the through hole 101 and slidably connected. A limiting ring block 4 is fixedly connected to the middle of the pressing column 3. The limiting ring block 4 is placed in the groove 102. A spring 5 is provided between the lower end face of the limiting ring block 4 and the lower inner wall of the groove 102. The spring 5 is sleeved on the lower outside of the pressing column 3. At the same time, a rubber pad 6 is provided at the bottom of the pressing column 3. A support frame 10 is provided above the positioning block 1. A pin 7 is provided above the support frame 10. An eccentric pressing column 8 is fixedly connected to the middle of the pin 7. A toggle rod 9 is provided on the side of the eccentric pressing column 8.

[0024] In this embodiment, the through hole 101 communicates with the insertion hole 2 below, and the clamping post 3 extends through the top of the positioning block 1, while the protruding end of the clamping post 3 is placed between the support frames 10.

[0025] Furthermore, the lower end of the limiting ring block 4 is fixedly connected to the top of the spring 5, and the bottom of the spring 5 is fixedly connected to the inner wall below the ring groove 102.

[0026] Furthermore, an arc-shaped groove 301 is provided above the clamping column 3, and the arc-shaped groove 301 is pressed into the lower side of the eccentric clamping column 8.

[0027] Furthermore, the rubber pad 6 is placed below the through hole 101, and the bottom of the rubber pad 6 is flush with the bottom of the through hole 101.

[0028] A clamping column 3 is inserted into the through hole 101 above the positioning block 1. A spring 5 is provided between the limiting ring block 4 in the middle of the clamping column 3 and the ring groove 102 in the positioning block 1. The spring 5 restricts the clamping column 3 in the through hole 101. At the same time, the spring 5 can reset the clamping column 3. An eccentric pressing column 8 and a toggle rod 9 are provided above the positioning block 1. When the toggle rod 9 is pressed down to a horizontal state, the eccentric pressing column 8 presses the clamping column 3 down.

[0029] In this embodiment, the forklift's insert plate is inserted into the insertion hole 2, and the bottom of the rubber pad 6 presses against the upper surface of the forklift's insert plate.

[0030] The rubber pad 6 located below the clamping column 3 will press against the forklift's insert plate, thus increasing the friction between the positioning block 1 and the insert plate.

[0031] In this embodiment, a hanger 11 is provided at the lower center of the positioning block 1, and a support column 12 is provided between the lower parts of the hanger 11.

[0032] Furthermore, the middle of the support column 12 is fitted with a hook assembly 13 above it.

[0033] After the hook assembly 13 is installed below the positioning block 1, the hook assembly 13 will hook onto the rope that passes through the inside of the large coil, so that the large coil can be lifted by a forklift.

[0034] Working principle:

[0035] A through hole 101 is provided above the middle of the positioning block 1, and a groove 102 is provided inside the through hole 101. A clamping pin 3, a limiting ring block 4, and a rubber pad 6 are inserted into the through hole 101. The limiting ring block 4 is placed inside the groove 102. At the same time, a spring 5 is provided between the lower end face of the limiting ring block 4 and the lower inner wall of the groove 102. The spring 5 fixes the limiting ring block 4, the clamping pin 3, and the rubber pad 6 in the through hole 101. An eccentric pressure pin 8 is provided between the support frames 10 provided above the positioning block 1, and a pin 7 is inserted into the eccentric position of the eccentric pressure pin 8, so that the eccentric pressure pin 8 can rotate with the pin 7. The side is provided with a lever 9. When the forklift plate is inserted into the insertion hole 2 in the middle of the positioning block 1, the upper and lower planes of the insertion plate are aligned with the upper and lower planes inside the insertion hole 2. At this time, the lever 9 is pressed to a horizontal state, so that the protruding part of the eccentric pressure column 8 after rotation presses into the arc-shaped groove 301 at the top of the pressure column 3, and the pressure column 3 is pressed into the insertion hole 2. In this way, the rubber pad 6 will be firmly pressed on the upper plane of the forklift plate, thereby increasing the friction between the rubber pad 6 and the insertion and removal of the forklift, preventing the positioning block 1 from slipping off the plate. Then, the hook assembly 13 provided below the positioning block 1 is used to hook it above the rope passing through the large coil.

[0036] In addition, when it is necessary to remove the positioning block 1, the lever 9 is raised to a vertical position, so that the eccentric pressure column 8 rotates and the protruding part is disengaged from the top of the pressure column 3. At the same time, the spring 5 lifts the pressure column 3 upward, so that the rubber pad 6 is disengaged from the forklift's insert plate.
