Description

Technical Field

[0001] The utility model relates to the technical field of barreled material pouring, in particular to a double-headed locking pin shaft. Background Art

[0002] In the factory, a barrel tipping truck is usually used to grab and pour round barrels. The barrel edge dimensions of general standard round barrels are basically similar. However, the barrels used in some specific industries are very different from the standard barrels. After the eagle head of the barrel tipping truck grabs a special barrel, it cannot be locked and fixed. During the working process, dangerous situations such as barrel dropping may occur, which even threatens the personal safety of the operator. Therefore, a double-headed locking pin shaft is proposed to solve the above problems. Content of the Utility Model

[0004] To achieve the above object, the utility model provides the following technical solution: A double-headed locking pin shaft, including an outer shell plate, and a round barrel grabbing structure is arranged inside the outer shell plate.

[0005] The round barrel grabbing structure includes an upper eagle head rotatably installed inside the outer shell plate, a pin shaft fixedly installed inside the outer shell plate, a lower eagle head rotatably installed outside the pin shaft and penetrating to its left side, a double-joint connecting rod rotatably installed on the surface of the upper eagle head, a return spring movably installed on the right sides of the upper eagle head and the lower eagle head, two locking holes penetrating to its back are opened on the surface of the outer shell plate, a locking plug is movably installed inside the locking holes, an installation base is arranged at the bottom of the outer shell plate, and a plurality of installation bolts penetrating to the inside of the outer shell plate are threadedly installed at the bottom of the installation base.

[0006] Further, the inside of the outer shell plate is a hollow structure, and the outside of the upper eagle head is in the shape of an eagle head.

[0007] Further, the pin shaft is located near the lower left corner of the outer shell plate, and the lower eagle head is located at the bottom of the upper eagle head.

[0008] Further, the double-joint connecting rod is rotatably installed on the surface of the lower eagle head, and the double-joint connecting rod is located at one end near the bottom of the lower eagle head.

[0009] Further, the return spring is located on the right side of the double-joint connecting rod.

[0010] Further, the two locking holes are distributed obliquely upward at two points on the surface of the outer shell plate, and the diameter of the second half of the locking plug is smaller than the diameter of its first half.

[0011] Further, the installation base and the outer shell plate are fixedly connected by a plurality of installation bolts.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0013] For this double-headed locking pin shaft, the device can be controlled to work by connecting it to the tipping cart through the mounting base. When the first layer of limit is applied to the upper eagle beak, the upper eagle beak and the lower eagle beak cooperate to grab a standard barrel for tipping. When the second layer of limit is applied to the upper eagle beak, the upper eagle beak and the lower eagle beak cooperate to grab a special barrel type for tipping. This device can freely adjust to grab special barrels and standard barrels, thus achieving the effect of firm grasping and locking. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , a double-headed locking pin shaft in this embodiment includes an outer shell plate 1. The inside of the outer shell plate 1 is a hollow structure, and a round barrel grasping structure is provided inside the outer shell plate 1.

[0020] The round barrel grasping structure includes an upper eagle beak 2 rotatably installed inside the outer shell plate 1. The outside of the upper eagle beak 2 is in the shape of an eagle beak. A pin shaft 101 is fixedly installed inside the outer shell plate 1. The pin shaft 101 is located near the lower left corner of the outer shell plate 1. A lower eagle beak 3 is rotatably installed outside the pin shaft 101 and penetrates to its left side. The lower eagle beak 3 is located at the bottom of the upper eagle beak 2. The lower eagle beak 3 is supported by the pin shaft 101 to rotate at the bottom of the upper eagle beak 2.

[0021] The surface of the upper cusp 2 is rotatably installed with a double-jointed connecting rod 4. The double-jointed connecting rod 4 is rotatably installed on the surface of the lower cusp 3. The upper cusp 2 and the lower cusp 3 are connected by the installed double-jointed connecting rod 4. At this time, when the upper cusp 2 rotates, it can drive the lower cusp 3 to rotate synchronously through the double-jointed connecting rod 4. One end of the double-jointed connecting rod 4 is located near the bottom of the lower cusp 3. A return spring 5 is movably installed on the right side of the upper cusp 2 and the lower cusp 3. The return spring 5 is located on the right side of the double-jointed connecting rod 4. By installing the return spring 5, the upper cusp 2 and the lower cusp 3 can be pulled back to their original positions. Two locking holes 6 penetrating through to the back of the outer shell plate 1 are opened on the surface of the outer shell plate 1. The two locking holes 6 are distributed obliquely upward at two points on the surface of the outer shell plate 1. A locking pin 7 is movably installed inside the locking hole 6. The diameter of the second half of the locking pin 7 is smaller than that of its first half. Inserting the locking pin 7 into the two locking holes 6 respectively can limit different positions of the upper cusp 2. An installation base 8 is provided at the bottom of the outer shell plate 1. A plurality of installation bolts 9 penetrating through to the inside of the outer shell plate 1 are threadedly installed at the bottom of the installation base 8. The installation base 8 and the outer shell plate 1 are fixedly connected by the plurality of installation bolts 9.

[0022] The working principle of the above embodiment is as follows:

[0023] During use, connect the installation base 8 with the inverted barrel truck to control the device to work. Insert the locking pin 7 into the two locking holes 6 respectively to limit different positions of the upper cusp 2. When the first layer of limit is applied to the upper cusp 2, the upper cusp 2 and the lower cusp 3 cooperate to grab the standard barrel for dumping. When the second layer of limit is applied to the upper cusp 2, the upper cusp 2 and the lower cusp 3 cooperate to grab the special barrel type for dumping. After dumping, the barrel is separated from the upper cusp 2 and the lower cusp 3. At this time, affected by the pulling force of the return spring 5, the upper cusp 2 and the lower cusp 3 can automatically return to their original positions.
