[0002] Suspension conveyor is a commonly used continuous conveying equipment, which is widely used to continuously convey various finished goods and bulk materials in containers or bags in factories. It can also be used to convey workpieces between processes in the assembly lines of various industrial departments, complete various processes, and realize the comprehensive mechanization of conveying and process operations. Suspension conveyors can be arranged arbitrarily in three-dimensional space, and the line can go up and down and turn in space. The layout is flexible and occupies a small area.

[0003] At present, the current suspension conveyor will encounter the following problems and challenges during use:

[0004] 1. Due to long-term friction and the impact of materials, the chain may be worn or even broken. When the chain breaks accidentally while moving on a slope, the chain, trolley and sling will move backwards, affecting the conveying effect and safety.

[0005] 2. The hook is a key component for fixing materials on the chain. The hook may fail during use, causing the material to fall off or fall, leading to safety problems and production delays.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0010] The mobile trolley is equipped with multiple suspension shafts arranged at equal intervals, and pairs of hooks are installed under the main body of the suspension shaft. A first connecting rod and a second connecting rod are installed between the pairs of hooks, and the facing inner ends of the first connecting rod and the second connecting rod are hinged by a locking pin shaft.

[0011] Furthermore, the multiple rotating shafts are arranged at equal intervals, and the axes of the rotating shafts are arranged in a horizontal direction.

[0012] Furthermore, the backstop plate is composed of a rotating portion, a straight plate portion and an arc portion.

[0013] Furthermore, the rotating part is sleeved on the rotating shaft.

[0014] Furthermore, the straight plate portion is fixedly connected to one side of the main body of the rotating portion along the horizontal direction.

[0015] Furthermore, the arc portion is fixedly connected to the lower part of the main body of the rotating portion.

[0016] Furthermore, the arc portion is arranged toward the traveling direction of the catenary, and the shape of the arc portion is adapted to the shape of the roller of the wheel set.

[0017] Furthermore, the facing outer ends of the first connecting rod and the second connecting rod are hingedly connected to the hook via a support.

[0018] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0019] The wheel set in the utility model can push the arc portion of the anti-recoil plate to swing along the rotating shaft during normal travel. When the catenary breaks and the wheel set moves in the reverse direction, the straight plate portion plays a role in limiting rotation, restricting the wheel set, the catenary and the mobile trolley from moving in the reverse direction, thus playing a role in anti-recoil protection.

[0020] The locking pin in the utility model can connect the first connecting rod and the second connecting rod together, limit the opening and closing of the hook, and firmly hang the workpiece on the hook to prevent the material from loosening, thereby playing a protective function and avoiding the problem of the material falling off or falling.

DETAILED DESCRIPTION

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0028] like Figure 1-Figure 4 As shown together, the utility model provides a hanging conveyor protection device, including a catenary track 1, a wheel set 2 is installed on the catenary track 1, the wheel set 2 is installed in a wheel frame 3, the main body of the wheel frame 3 passes through a catenary 13 below and is connected to a moving trolley 4, and the catenary 13 drives the wheel set 2 to move along the catenary track 1 through the wheel frame 3.

[0029] The catenary track 1 is an H-shaped steel track or an I-shaped steel track, and a plurality of rotating shafts 5 are provided on the web of the steel track, and the rotating shafts 5 are arranged near the upper wing plate of the steel track. The plurality of rotating shafts 5 are arranged at equal intervals, and the axis of the rotating shafts 5 is arranged in a horizontal direction.

[0030] The two ends of the rotating shaft 5 are respectively provided with anti-recognition plates 6 rotatably connected thereto. The anti-recognition plates 6 are distributed on both sides of the steel rail web. The anti-recognition plates 6 can swing along the rotating shaft 5 at a certain angle, and the swinging direction is the same as the traveling direction of the catenary 13.

[0031] The stop plate 6 is composed of a rotating part 601 , a straight plate part 602 and an arcuate part 603 . The rotating part 601 is sleeved on the rotating shaft 5 . The straight plate part 602 is fixedly connected to one side of the main body of the rotating part 601 along the horizontal direction. The arcuate part 603 is fixedly connected to the lower part of the main body of the rotating part 601 .

[0032] The arc portion 603 is arranged toward the traveling direction of the catenary 13, and the shape of the arc portion 603 is adapted to the roller shape of the wheel set 2. The wheel set 2 can push the arc portion 603 to swing along the rotating shaft 5 during normal travel. When the wheel set 2 travels in the reverse direction, the straight plate portion 602 plays a role in limiting the rotation and restricting the wheel set 2 from traveling in the reverse direction.

[0033] A plurality of suspension shafts 7 arranged at equal intervals are installed on the mobile vehicle 4 , and hooks 8 arranged in pairs are installed below the main bodies of the suspension shafts 7 .

[0034] A first connecting rod 9 and a second connecting rod 10 are installed between the paired hooks 8. The facing outer ends of the first connecting rod 9 and the second connecting rod 10 are hingedly connected to the hooks 8 via a support 11, and the facing inner ends of the first connecting rod 9 and the second connecting rod 10 are hingedly connected via a locking pin 12.
