Description

Technical Field

[0001] This utility model belongs to the field of machining technology, and in particular relates to a safe removal and unloading device for welded pins. Background Technology

[0002] Construction machinery refers to the general term for mechanical equipment used in fields such as engineering construction, land resource development, agricultural, forestry and water conservancy construction, transportation construction, and municipal engineering construction to complete various engineering operations in a mechanized manner. It is a core tool for achieving efficient, precise, and large-scale construction in the engineering construction field, significantly improving the efficiency, quality, and safety of engineering construction by replacing or assisting manual labor.

[0003] Construction machinery includes excavators, cranes, etc. At the boom hinge of excavators, cranes, etc., there are pin-shaft welded components used for joint folding and load-bearing. The pin-shaft welded components are made by welding a pin and a welding plate. After welding, the large pin and welding plate assembly is quite heavy, requiring tools for unloading and handling.

[0004] There are currently two handling solutions:

[0005] 1. Manual clamping solution: Requires at least 2 people to operate together. The large weight of the pin results in insufficient clamping force, which can easily lead to the pin falling due to operational errors, causing damage to the workpiece and injury to personnel.

[0006] 2. Electromagnetic adsorption solution: The annular protrusion at the weld of the large pin shaft reduces the effective adsorption area of ​​the electromagnet, and the adsorption force cannot overcome its own weight. It is prone to demagnetization and failure at high temperatures, and there is a risk of falling. Utility Model Content

[0007] The purpose of this invention is to address the aforementioned technical problems by providing a safe unloading device for welded pins, which achieves the effect of safely and reliably unloading materials.

[0008] In view of this, the present invention provides a safe removal and unloading device for welded pins, comprising:

[0009] A sliding shaft, wherein a hook is fixedly connected to the middle of the sliding shaft by a locking structure;

[0010] The pallet has two plates, which are respectively located on both sides of the hook. The upper part of the pallet is slidably mounted on the sliding shaft, and the lower ends of the two pallets are respectively used to support the lower ends of the welding plate. The pallets are fixed to the sliding shaft by a first fastening structure.

[0011] In this technical solution, after the pin and the welding plate are welded, the pin welded part needs to be removed and moved away. The left support plate can be fixed to the sliding shaft through the first fastening structure, and the lower end of the left support plate can be extended to the lower end of the welding plate. At this time, the right support plate is not fastened to the sliding shaft, but is slidably set on the sliding shaft and away from the left support plate. The right support plate can be pushed closer to the left support plate until the lower end of the right support plate also extends to the lower end of the welding plate. Then, the right support plate is fixed through the first fastening structure. Then, the safety hoist can be hoisted onto the hook to remove the pin welded part and move away. This unloading device can safely and reliably unload materials.

[0012] Furthermore, the end of the support plate facing the pin is the holding end, and the end of the holding end facing the pin is arc-shaped. The arc-shaped surface of the holding end is used to abut against the outer periphery of the pin.

[0013] Furthermore, the tray is L-shaped.

[0014] In this technical solution, the ends of the two support plates are arc-shaped, which can form a state of holding the outer periphery of the pin. In this way, the support plates drag the welding plate below the welding plate and the ends hold the outer periphery of the pin, which can make the clamping state of the pin welded parts more stable, safe and reliable.

[0015] Furthermore, the first fastening structure includes:

[0016] The first fastening hole is formed on the support plate and is perpendicular to and connected to the hole through which the sliding shaft passes on the support plate;

[0017] The first bolt is threadedly connected to the first fastening hole and its end can abut against the outer periphery of the sliding shaft.

[0018] Furthermore, the locking structure includes:

[0019] A locking hole is provided on the hook, and the locking hole is perpendicular to and communicates with the hole through which the sliding shaft passes on the hook;

[0020] A locking bolt, wherein the locking bolt is threadedly connected to a locking hole and its end can abut against the outer periphery of the sliding shaft.

[0021] Furthermore, a limiting structure is provided on the sliding shaft to prevent the tray from sliding off the sliding shaft.

[0022] Furthermore, the limiting structure includes limiting pins disposed at both ends of the sliding shaft.

[0023] In this technical solution, the limiting pin can be fixed to the sliding shaft by passing through it and being welded or riveted to it.

[0024] Furthermore, the holding end of the tray can be detachably replaced via a replacement structure.

[0025] In this technical solution, when the diameter of the pin is too large or too small and there is a large difference between it and the arc-shaped surface of the holding end of the universal pallet, it is necessary to replace the holding end with an arc-shaped surface that matches the outer circumference of the pin, so as to ensure the safety and reliability of the packaging clamping.

[0026] Furthermore, the replacement structure includes:

[0027] The holding end has a connection notch that matches the head of the tray, and the connection notch extends outward to form a positioning pin.

[0028] A positioning hole is provided on the head of the tray, and the positioning hole is matched with a positioning pin.

[0029] The second fastening structure is used to keep the holding end fixed to the tray head.

[0030] Furthermore, the second fastening structure includes:

[0031] The second fastening hole is located on the side end of the pallet head;

[0032] The second bolt passes through the holding end and is threaded into the second fastening hole.

[0033] The beneficial effects of this utility model are:

[0034] 1. After the pin and the welding plate are welded, the pin welded part needs to be removed and moved away. The left support plate can be fixed to the sliding shaft through the first fastening structure, and the lower end of the left support plate can be extended to the lower end of the welding plate. At this time, the right support plate is not fastened to the sliding shaft, but is slidably set on the sliding shaft and away from the left support plate. The right support plate can be pushed closer to the left support plate until the lower end of the right support plate also extends to the lower end of the welding plate. Then, the right support plate is fixed through the first fastening structure. Then, the safety hoist can be hoisted onto the hook to remove the pin welded part and move away. This unloading device can safely and reliably unload materials.

[0035] 2. The ends of the two support plates are rounded, which can form a state of holding the outer circumference of the pin. In this way, the support plates drag the welding plate below the welding plate and the ends hold the outer circumference of the pin, which can make the clamping state of the pin welded parts more stable, safe and reliable.

[0036] 3. The limiting pin can be fixed to the sliding shaft by passing through it and by welding or riveting.

[0037] 4. When the diameter of the pin is too large or too small and there is a large difference between it and the arc-shaped surface of the holding end of the universal pallet, it is necessary to replace the holding end with an arc-shaped surface that matches the outer circumference of the pin to ensure the safety and reliability of the packaging clamping.

[0051] Sliding shaft 1, with a hook 2 fixedly connected in the middle by a locking structure 4;

[0052] There are two support plates 3, which are respectively located on both sides of the hook 2. The upper end of the support plate 3 is slidably mounted on the sliding shaft 1, and the lower ends of the two support plates 3 are respectively used to support the lower ends of the welding plate 12. The support plates 3 and the sliding shaft 1 are fixed by the first fastening structure 5.

[0053] After the pin 11 and the welding plate 12 are welded, the welded pin 11 needs to be removed and moved away. The left support plate 3 can be fixed to the sliding shaft 1 through the first fastening structure 5, and the lower end of the left support plate 3 can be extended to the lower end of the welding plate 12. At this time, the right support plate 3 is not fastened to the sliding shaft 1, but is slidably set on the sliding shaft 1 and away from the left support plate 3.
