Description

Technical Field

[0001] The present invention relates to the technical field of coal mine transportation safety, and particularly to a safety device for preventing pinching during uncoupling and coupling. Background Art

[0002] At present, flatbed trucks are commonly used in coal mine transportation and railway material transportation. In particular, the connecting pins of the three-ring chains of mine cars have the disadvantages of difficult coupling and uncoupling, long time consumption, and relatively large overall weight when loaded, resulting in unsafe coupling and uncoupling. Especially when parking on a slope with heavy loads, the time for uncoupling is relatively long. Workers on site uncouple and couple by hand, which is prone to hurting people when the vehicle returns, seriously threatening the lives of miners.

[0003] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following combines the drawings to describe in detail the specific embodiments of the present invention, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0018] Unless otherwise clearly stated, throughout the specification and claims, the term "comprising" or its variations such as "comprises" or "including" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0019] As Figures 1 to 3 shown, Figure 1 is a front view structural schematic diagram of the hook detaching and attaching anti-pinch safety device according to an embodiment of the present invention; Figure 2 is a top view structural schematic diagram of the hook detaching and attaching anti-pinch safety device according to an embodiment of the present invention; Figure 3 is a connecting structure schematic diagram of the connecting rod part of the hook detaching and attaching anti-pinch safety device according to an embodiment of the present invention.

[0020] A hook detaching and attaching anti-pinch safety device according to a preferred embodiment of the present invention is applied to a flatbed truck. The hook detaching and attaching anti-pinch safety device includes a connecting rod 1. A left protection block 2 is welded to the left end of the connecting rod 1. A left connecting part 3 is welded to the center of the left side of the left protection block 2. The left connecting part 3 is connected to a left block head connecting part 5 through a left adjusting pin shaft 4. The left block head connecting part 5 is welded to a left block head 6. A right protection block 7 is welded to the right end of the connecting rod 1. A right connecting part 8 is welded to the center of the right side of the right protection block 7. The right connecting part 8 is connected to a right block head connecting part 10 through a right adjusting pin shaft 9.

[0021] As Figure 4 shown, Figure 4 FIG. is a schematic structural view of the right block head of the hook detaching and attaching anti-pinch safety device according to an embodiment of the present invention. The right block head connecting part 10 is welded to the right block head 11.

[0022] In an embodiment of the present invention, the left protection block 2 and the right protection block 7 have the same structural dimensions and are both U-shaped structures. Their function is to prevent the flatbed truck from hurting people when the left block head 6 and the right block head 11 at both ends of the connecting rod 1 are hooking or unhooking the flatbed trucks, playing a role of blocking and isolating.

[0023] In an embodiment of the present invention, the upper and lower connecting blocks on the left connecting part 3 and the upper and lower connecting plates on the left block head connecting part 5 are staggered and are movably connected through the left adjusting pin shaft 4, and the upper and lower connecting blocks on the right connecting part 8 and the upper and lower connecting plates on the right block head connecting part 10 are staggered and are movably connected through the right adjusting pin shaft 9. Their function is to ensure the smooth movement of the flatbed truck during turning and other movements.

[0024] In practical applications, the working process of the hook detaching and attaching anti-pinch safety device of the present invention is as follows: When using the hook detaching and attaching anti-pinch safety device in this solution, hold the connecting rod 1 by hand. At this time, during the process of hooking and unhooking the left block head 6 at one end of the connecting rod 1 with the flatbed truck and hooking and unhooking the right block head 11 at the other end of the connecting rod 1 with the flatbed truck, since the left protection block 2 and the right protection block 7 are respectively provided at both ends of the connecting rod 1 and correspond to the left block head 6 and the right block head 11, they play a role of blocking and isolating during the hooking and unhooking process, ensuring the distance between the flatbed truck and the human hand. Thus, the problem that on-site workers unhook the hook by hand and are easily hurt by the returning vehicle, which seriously threatens the lives of miners, is solved. At the same time, the processing cost is low in terms of processing difficulty.

[0025] The processing requirements of this design are very low. This product can be processed in any way, with low cost and even capable of self-welding. It fully meets the requirements of the coal mining industry and can also be applied to the hook unhooking operation in other industries. In terms of the usage environment of the design, this device can be used in harsh environments without considering precision and manufacturing strength. Manufacturing methods such as casting, forging, turning, and welding are adopted, ignoring a series of harsh environments such as coal dust and dust impact, and even ignoring wear. Moreover, it is convenient to carry, can be replaced, and has a high reliability factor.

[0026] In summary, the hook unhooking anti-pinch safety device of the present invention has the following beneficial effects:

[0027] 1. In terms of the usage environment of the design, this device can be used in harsh environments without considering precision and manufacturing strength.
