Description

Technical Field

[0001] The utility model relates to the technical field of chain conveyors, in particular to a protection mechanism applied to the end of a chain conveyor. Background Art

[0002] Chain conveyor is a conveyor that utilizes chains to pull and carry materials, or slats installed on the chains, metal mesh belts and rollers to carry materials. It can be divided into chain type, chain plate type, chain mesh type and slat type, etc. It is often combined with other conveyors, lifting devices, etc. to form production lines with various functions.

[0003] When the existing chain conveyor is in use, there are generally no protective measures at both ends of the chain conveyor. Since the use environment is mostly inside a workshop, there will be people or materials moving back and forth for transportation, which makes the two ends susceptible to collision with objects, causing the conveyor belt to deform or be damaged, thus affecting the use of the chain conveyor. For this reason, we propose a protective mechanism applied to the end of the chain conveyor to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a protective mechanism applied to the end of a chain conveyor.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A protective mechanism applied to the end of a chain conveyor, comprising a conveyor frame, a mounting frame fixedly connected to the top surface of the conveyor frame, and a chain conveyor body installed inside the mounting frame, an end head protective cover abutting the inner side of the mounting frame, and a mounting plate fixedly connected to the top inner wall of the end head protective cover, the outer side of the end head protective cover is hinged to one end of a hinged rod, and the other end of the hinged rod is hinged to a connecting slider, and the connecting slider is slidably connected to the protective outer plate.

[0007] Preferably, a slide groove compatible with the connecting slider is opened on the inner side of the protective outer plate, and the inner wall of the slide groove is welded to one end of the buffer spring, and the other end of the buffer spring is welded to the surface of the connecting slider. The buffer spring can buffer the collision of the protective outer plate through its own elastic force.

[0008] Preferably, the cross-section of the end protective cover is set to be U-shaped, and the surface width of the end protective cover is the same as the spacing between the two groups of mounting frames. By making the surface width of the end protective cover the same as the spacing between the two groups of mounting frames, the installation of the end protective cover can be facilitated.

[0009] Preferably, the top surface of the end protective cover is fixedly connected with a fixed block, and the interior of the fixed block is slidably connected with a connecting rod, and one end of the connecting rod is fixedly connected with an adjusting clamp, which can facilitate the clamping and limiting function of the end protective cover.

[0010] Preferably, a circular hole adapted to the connecting rod is opened inside the fixed block, and the other end of the connecting rod is fixedly connected to a limiting plate. The surface dimensions of the adjusting splint and the limiting plate are larger than the circular hole opened inside the fixed block. The connecting rod can be conveniently moved in the circular hole through the circular hole opened inside the fixed block.

[0011] Preferably, a limiting bolt is threadedly inserted into the top surface of the fixing block, and one end of the limiting bolt inserted into the fixing block abuts against a connecting rod, and the connecting rod can be limited by the limiting bolt.

[0012] Preferably, an anti-skid rubber pad is glued to the inner side of the adjustment splint, and a plurality of groups of anti-skid rubber strips are arranged at equal distances on the inner side of the anti-skid rubber pad, and the friction force on the surface of the anti-skid rubber pad can be increased by the plurality of groups of anti-skid rubber strips.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The device can protect both ends by placing the end protection covers at both ends of the chain conveyor body. At the same time, through the elastic force of the buffer spring itself, when the protective outer plate is collided, the connecting slider can slide along the inside of the protective outer plate, which can effectively buffer the collision force and further improve the overall protection effect of the end protection cover.

[0015] 2. The device can move the connecting rod inside the fixed block by pulling the adjusting clamp. When the two sets of adjusting clamps are engaged with the outside of the mounting frame, the limiting bolts can be turned to make them contact with the surface of the connecting rod, thereby facilitating the limiting of the connecting rod. At the same time, the friction between the inner side of the adjusting clamp and the mounting frame can be increased by the anti-slip rubber pad and the anti-slip rubber strip, thereby facilitating the clamping stability of the adjusting clamp.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A protective mechanism applied to the end of a chain conveyor includes a conveyor frame 1, a mounting frame 2 is fixedly connected to the top surface of the conveyor frame 1, and a chain conveyor body 3 is installed inside the mounting frame 2, an end protection cover 4 is abutted on the inner side of the mounting frame 2, and a mounting plate 5 is installed on the top inner wall of the end protection cover 4 by bolts, the mounting plate 5 is installed by bolts, and can be disassembled and installed according to different usage requirements, the outer side of the end protection cover 4 is hinged to one end of a hinged rod 6, and the other end of the hinged rod 6 is hinged to a connecting slider 7, the connecting slider 7 is slidably connected to a protective outer plate 8, and the protective outer plate 8 can increase the protective effect of the end protection cover 4.

[0023] Further, see Figure 2 and Figure 3 It can be known that a sliding groove compatible with the connecting slider 7 is opened on the inner side of the protective outer plate 8, and the inner wall of the sliding groove is welded to one end of the buffer spring 9, and the other end of the buffer spring 9 is welded to the surface of the connecting slider 7. Through the sliding groove opened on the inner side of the protective outer plate 8, the connecting slider 7 can be easily moved in the sliding groove, which plays the role of limiting the connection of the protective outer plate 8.

[0024] Further, see Figure 1 and Figure 2 It can be seen that the cross-section of the end protection cover 4 is set to be U-shaped, and the surface width of the end protection cover 4 is the same as the spacing between the two sets of mounting frames 2. By setting the cross-section of the end protection cover 4 to be U-shaped, it can facilitate the protection of the end of the chain conveyor body 3.

[0025] Further, see Figure 3 and Figure 4It can be known that the top surface of the end protective cover 4 is fixedly connected with a fixed block 10, and the interior of the fixed block 10 is slidably connected with a connecting rod 11, and one end of the connecting rod 11 is fixedly connected with an adjusting clamp 12. The sliding connection between the fixed block 10 and the connecting rod 11 can facilitate the adjustment of the adjusting clamp 12, thereby facilitating the disassembly and installation of the end protective cover 4.

[0026] Further, see Figure 2 and Figure 4 It can be known that a circular hole adapted to the connecting rod 11 is opened inside the fixed block 10, and the other end of the connecting rod 11 is fixedly connected to a limiting plate 13. The surface dimensions of the adjusting splint 12 and the limiting plate 13 are larger than the size of the circular hole opened inside the fixed block 10. The limiting plate 13 can facilitate the limiting of the connecting rod 11.

[0027] Further, see Figure 2 and Figure 4 It can be known that a limiting bolt 14 is threadedly inserted into the top surface of the fixing block 10, and one end of the limiting bolt 14 inserted inside the fixing block 10 abuts against the connecting rod 11. The limiting bolt 14 abuts against the surface of the connecting rod 11, which facilitates the function of limiting the connecting rod 11.

[0028] Further, see Figure 3 and Figure 4 It can be known that an anti-skid rubber pad 15 is glued to the inner side of the adjusting splint 12, and a plurality of groups of anti-skid rubber strips 16 are arranged at equal distances on the inner side of the anti-skid rubber pad 15. The anti-skid rubber pad 15 and the anti-skid rubber strips 16 can increase the friction between the adjusting splint 12 and the mounting frame 2, thereby improving the clamping stability of the adjusting splint 12.

[0029] Working principle: When the utility model is in use, when the conveyor frame 1 is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 , by engaging the end head protection cover 4 at the two ends of the chain conveyor body 3 and rotating the limit bolt 14, the limit bolt 14 can be moved away from the surface of the connecting rod 11. At this time, pulling the adjusting clamp plate 12 can make the adjusting clamp plate 12 drive the connecting rod 11 to slide inside the fixing block 10. When the two sets of adjusting clamp plates 12 drive the anti-skid rubber pads 15 and the anti-skid rubber strips 16 to conflict with the outer side of the mounting frame 2, the limit bolt 14 can be rotated to make the limit bolt 14 conflict with the surface of the connecting rod 11, so that the end head protection cover 4 can be limited at the two ends of the chain conveyor body 3, so that the end head protection cover 4 can be protected, and when the protective outer plate 8 is collided, the protective outer plate 8 can drive the connecting slider 7 to slide inside the protective outer plate 8. At this time, the elastic force of the buffer spring 9 itself can play a role in facilitating buffering and protecting the end head protection cover 4;

[0030] The above is the entire working principle of the utility model.
