Description

Technical Field

[0001] The utility model relates to a hanging and unloading structure, in particular to an automatic hanging and unloading structure for a hook based on gravity, belonging to the technical field of hooks. Background Art

[0002] Hooks are usually installed on cranes, and their main function is to connect the crane wire rope with the object being lifted. Hooks play an important role in the process of transporting goods. Different from traditional manpower handling of goods, using a crane with a hook can easily transport the goods to the required location. With the improvement of productivity, logistics is relatively developed, and the volume of cargo transportation is large, so the use of cranes and hooks is more frequent. Now, when using hooks, manpower is usually used to assist in unloading the hooks.

[0003] Generally, when using the hook, the cargo is first hung on the rope, and then the cargo is lifted up by the crane, and then the cargo is transported to the required location, and then the crane lowers the cargo. During the lowering process, the rope connected to the cargo will still be hanging on the hook. At this time, the worker needs to take the rope off the hook. However, in this process, a worker needs to be arranged separately to wait at the cargo unloading point. Moreover, when taking the rope, if the cargo is high or the unloading location is more dangerous, the worker will be in danger of taking the rope, which may cause a safety accident.

[0004] Therefore, there is an urgent need to improve the gravity-based automatic hooking and unloading structure to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a gravity-based automatic hook hanging and unloading structure, wherein the two ends of the deflection rod are respectively connected to a hook body and a counterweight box. After the goods are hung on the hook body, the deflection rod will be in a vertical state. When the goods are unloaded, the deflection rod will be no longer disturbed by external forces, and the upper end of the deflection rod will deflect toward the position of the center of gravity of the counterweight box, and the lower end of the deflection rod will deflect to a position away from the center of gravity of the counterweight box. The rope on the goods will fall off the hook body, and then before hanging new goods, it is only necessary to manually move the counterweight box. In this process, the deflection rod is deflected by gravity to achieve unhooking the rope on the upper end of the goods, thereby avoiding safety accidents caused by unloading goods. In some locations with higher risk factors, it is possible to save workers from manually unhooking the cargo ropes, thereby reducing hidden dangers and ensuring safety.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include: a gravity-based hook automatic hanging and unloading structure, including a main frame, a deflection rod is rotatably connected to the main frame, one end of the deflection rod is threadedly connected to the hook body, the other end of the deflection rod is fixedly connected to a counterweight box, and the center of gravity of the counterweight box is far away from the center of gravity of the deflection rod;

[0007] A U-shaped plate is fixedly connected to the main frame, and a square hole is opened on the U-shaped plate. A clamping assembly for clamping the deflection rod is provided on the side wall of the counterweight box close to the U-shaped plate. Two arc-shaped groove plates are fixedly connected in the main frame, and limiting rods are fixedly connected to the side walls on both sides of the deflection rod, and the ends of the two limiting rods away from the deflection rod are respectively slidably connected to the two arc-shaped groove plates.

[0011] Preferably, the clamping assembly includes a grooved block, two sliding blocks, a spring plate and two telescopic springs, the side wall of the grooved block on one side is fixedly connected to the side wall of the counterweight box on one side, the two sliding blocks are respectively slidably connected to the side walls on both sides of the grooved block, the spring plate is fixedly connected in the grooved block, and the two telescopic springs are respectively fixedly connected to the side walls on both sides of the spring plate.

[0015] 1. The two ends of the deflection rod are respectively connected to the hook body and the counterweight box. After the goods are hung on the hook body, the deflection rod will be in a vertical state. When the goods are unloaded, the deflection rod will no longer be disturbed by external force. The upper end of the deflection rod will deflect toward the position of the center of gravity of the counterweight box, and the lower end of the deflection rod will deflect to a position away from the center of gravity of the counterweight box. The rope on the goods will fall off the hook body, and then before hanging new goods, you only need to manually move the counterweight box. In this process, the deflection rod is deflected by gravity to unhook the rope on the upper end of the goods, avoiding safety accidents caused by unloading goods. In some locations with higher risk factors, workers can be saved from manually unhooking the cargo ropes, reducing hidden dangers and ensuring safety.

[0016] 2. The clamping state between the clamping assembly and the square hole makes the deflection rod and the hook body in an inclined state in the initial state, which is more conducive to hanging the rope on the cargo. At the same time, it also ensures that the deflection rod will not be deflected by the influence of the counterweight box in the initial state, and the method of realizing the clamping state between the clamping assembly and the square hole is simple. It only needs to manually move the counterweight box, which is simple to operate, saving time and effort. The rope on the cargo will fall off the hook, and then before hanging new cargo, you only need to manually move the counterweight box. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] like Figure 1-Figure 8 As shown, the gravity-based hook automatic hanging and unloading structure provided in this embodiment includes a main frame 1, a deflection rod 2 is rotatably connected to the main frame 1, one end of the deflection rod 2 is threadedly connected to a hook body 3, and the other end of the deflection rod 2 is fixedly connected to a counterweight box 4, and the center of gravity of the counterweight box 4 is far away from the center of gravity of the deflection rod 2. The counterweight box 4 is located at the upper end of the deflection rod 2. When the deflection rod 2 is in a vertical state, without external interference, the upper end of the deflection rod 2 will deflect toward the position of the center of gravity of the counterweight box 4, and the lower end of the deflection rod 2 will deflect to a position away from the center of gravity of the counterweight box 4. A plurality of counterweight blocks 20 are movably connected in the counterweight box 4, and the number of the counterweight blocks 20 determines the weight of the counterweight box 4. The quantity of the counterweight 20 can be selected according to actual needs. A groove 21 is provided on the side wall of one side of the counterweight 20. The groove 21 is convenient for manual taking. The upper end surface of the counterweight box 4 is hinged with a baffle 22, and the lower end surface of the counterweight box 4 is fixedly connected with a threaded fixing block 23. The threaded fixing block 23 is threadedly connected with a threaded pin 24. One end of the baffle 22 is movably connected with the threaded pin 24. After the counterweight 20 is installed into the counterweight box 4, the baffle 22 is lowered, and the threaded pin 24 is used to pass through the baffle 22, and then it is threadedly connected to the threaded fixing block 23. At this time, the baffle 22 can fix several counterweights 20 in the counterweight box 4 so that they will not fall off from the counterweight box 4.

[0029] A U-shaped plate 5 is fixedly connected to the main frame 1, and a square hole 6 is opened on the U-shaped plate 5. A clamping assembly 166 for clamping the deflection rod 2 is provided on the side wall of the counterweight box 4 close to the U-shaped plate 5. Two arc-shaped slot plates 7 are fixedly connected to the main frame 1. The side walls on both sides of the deflection rod 2 are fixedly connected to limit rods 8. The ends of the two limit rods 8 away from the deflection rod 2 are respectively slidably connected to the two arc-shaped slot plates 7. The two arc plates limit the deflection angle of the deflection rod 2. The deflection rod 2 is initially In the initial state, the clamping assembly 166 is clamped and fixed with the square hole 6. After the hook body 3 hooks the cargo, it is subjected to a downward force, causing the clamping assembly 166 to come out of the square hole 6, and then the deflection rod 2 will be in a vertical state. After the hook body 3 is detached from the cargo, it is only necessary to manually move the counterweight box 4 so that the clamping assembly 166 can be clamped in the square hole 6 again. When the clamping assembly 166 is clamped in the square hole 6, it also makes it easier for the hook body 3 to hook the cargo rope.

[0030] Among them, Figure 1 as well as Figure 8 As shown, the main frame 1 includes a left support member 9, a right support member 10 and a connecting load-bearing plate 11. One end of the left support member 9 and the right support member 10 are fixedly connected to the lower end surface of the connecting load-bearing plate 11. The upper end surface of the connecting load-bearing plate 11 is fixedly connected to a connecting threaded portion 12 for fixing the main frame 1. A No. 1 rotating portion 13 is fixedly connected to the inner side wall of one end of the left support member 9 away from the connecting load-bearing plate 11. A No. 2 rotating portion 14 is fixedly connected to the inner side wall of one end of the right support member 10 away from the connecting load-bearing plate 11. The left support member 9 and the right support member 10 clamp the deflection rod 2, and the gravity borne by the deflection rod 2 will also be dispersed to be borne by the left support member 9 and the right support member 10, and then transmitted to the connecting load-bearing plate 11, and the connecting threaded portion 12 is connected to the rope connection structure of the crane.

[0031] Further, such as Figure 1 As shown, the No. 1 rotating part 13, the No. 2 rotating part 14 and the deflection rod 2 are rotatably connected with a rotating shaft 15, and the rotating shaft 15 passes through the No. 1 rotating part 13, the No. 2 rotating part 14 and the deflection rod 2, and the side walls on both sides of the deflection rod 2 are respectively in contact with the end surface of the No. 1 rotating part 13 away from the left support member 9 and the end surface of the No. 2 rotating part 14 away from the right support member 10. After the left support member 9 and the right support member 10 limit the deflection rod 2, the deflection rod 2 rotates under the action of the rotating shaft 15, and the rotating shaft 15 is located at the lower center of the deflection rod 2, so as to facilitate the use with the counterweight box 4.

[0032] Furthermore, if Figure 1 as well as Figure 7As shown, the clamping assembly 166 includes a grooved block 16, two sliding blocks 17, a spring plate 18 and two telescopic springs 19. The side wall of the grooved block 16 is fixedly connected to the side wall of the counterweight box 4. The two sliding blocks 17 are respectively slidably connected to the side walls on both sides of the grooved block 16. The spring plate 18 is fixedly connected in the grooved block 16. The two telescopic springs 19 are respectively fixedly connected to the side walls on both sides of the spring plate 18. When the clamping assembly 166 is clamped in the square hole 6, the square hole 6 will squeeze the two sliding blocks 17, and then squeeze the two telescopic springs 19. When the two sliding blocks 17 pass through the square hole 6, under the action of the telescopic springs 19, the two sliding blocks 17 return to their initial state. At this time, when the two sliding blocks 17 are stuck in the square hole 6, the counterweight box 4 is clamped.

[0033] like Figure 1-Figure 8 As shown, the principle of the gravity-based automatic hook hanging and unloading structure provided in this embodiment is as follows: when in use, a plurality of counterweight blocks 20 are respectively clamped in the counterweight box 4, and under the action of the clamping assembly 166, the counterweight box 4 is moved to clamp in the square hole 6 of the U-shaped plate 5, and then the rope on the cargo is put on the hook body 3. When the hook is dragged by the downward force, the counterweight box 4 will be separated from the clamping state with the square hole 6 until it maintains a horizontal state. At this time, the center of gravity of the counterweight box 4 and the center of gravity of the deflection rod 2 are not on the same vertical line. When unloading the cargo, after the hook body 3 loses its downward force, the upper end of the deflection rod 2 will deflect toward the position of the center of gravity of the counterweight box 4, and the lower end of the deflection rod 2 will deflect to a position away from the center of gravity of the counterweight box 4, until it deflects to a certain angle, the rope on the cargo will fall off the hook, and then before hanging new cargo, you only need to manually move the counterweight box 4 so that the clamping assembly 166 can be re-clamped in the square hole 6. When the clamping assembly 166 is clamped in the square hole 6, it also makes it easier for the hook body 3 to hang the cargo rope.

[0034] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0035] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
