Problems solved by technology

Excavation roadways in existing coal mines are mostly constructed by fully-mechanized excavators, and the fully-mechanized excavator frequently extends the belt head-on. Due to the heavy weight of the buffer tail of the existing fully-mechanized excavator, it is difficult to pull and transport the buffer tail, which consumes a lot of man-hours, and there is a risk of broken ropes and injuries. , so we consider researching a light buffer tail to reduce the weight of the buffer tail, reduce the difficulty of pulling and transporting, improve construction efficiency, and ensure construction safety

Embodiment 1

[0034] refer to Figure 1 to Figure 2 , a light-duty tail buffer device for fully mechanized mining machines in coal mines, comprising a base 1, clamps 2 are fixedly connected to both sides of the upper end of the base 1, and an I-shaped steel runway 3 is fixedly connected to the upper end of the clamp 2, and the I-shaped A buffer mechanism 4 is installed on the upper surface of the steel runway 3 .

[0035] The buffer mechanism 4 includes a support arm 41, a limit block 42, a rotary joint 43, a connecting rod 44, a chute 45, a slide block 46, a push rod 47, a return spring 48, and a block 49. The specific connection method is as follows:

[0036] Both sides of the bottom end of the idler frame 5 are connected with a connecting rod 44 through the rotating joint 43, and the end of the connecting rod 44 away from the rotating joint 43 is rotatingly connected with a slider 46 and a push rod 47. The top of the I-beam runway 3 is provided with Chute 45, slide block 46 is slidably ...

Embodiment 2

[0052] Embodiment 2 On the basis of Embodiment 1, a vibration-absorbing member 73 is further provided. The arrangement of the vibration-absorbing member 73 can greatly increase the anti-vibration performance of the roller 7 .

[0053] At least one vibration absorber 73 is arranged radially inside the cavity 725;

[0054] The vibration damping elastic metal 731 adopts a spring, and the two sides of the elastic metal 731 are fixedly connected to the outer partition 722 and the inner partition 712 through the connecting block 732 respectively.

[0055] When the idler 7 vibrates under the action of an external force, the idler 7 drives the vibration absorber 73 to perform forced vibration. When the external force gradually increases, until the vibration frequency of the idler 7 is the same as the natural frequency of the elastic metal 731, the elastic The metal 731 resonates, absorbs most of the vibration energy of the idler 7 in the resonance, and converts this energy into heat e...

Abstract

The invention discloses a light tail buffer device for fully mechanized excavating machines in coal mines, which comprises a base, clamps are fixedly connected to both sides of the upper end of the base, the upper end of the clamps is fixedly connected to an I-steel runway, The upper surface of the I-beam runway is equipped with a buffer mechanism, the input end of the buffer mechanism is connected with a roller frame, and the top of the roller frame is fixedly connected with a suspension pulley, and the suspension pulleys on both sides Steel wire ropes are wound around them, and at least one idler roller is connected with the common steel wire rope between the hanging pulleys on both sides. The invention reduces the difficulty of pulling and transporting and ensures construction safety. In the roadway of fully mechanized excavators, the tail of the buffer machine is frequently pulled along the belt. When the tail of the buffer machine is pulled, the fully mechanized excavator is connected to the tail of the buffer machine through a chain or an anchor. It is found that the light buffer tail can effectively improve this situation, ensure construction safety, and reduce the difficulty of pulling and transporting.

Description

technical field [0001] The invention relates to the technical field of backhauling supporting facilities for fully mechanized excavators in coal mines, in particular to a light-duty tail buffer device for fully mechanized excavators in coal mines. Background technique [0002] At present, in the process of excavating coal mine roadways in my country, the most commonly used technology is the comprehensive mechanized excavation technology. This technology mainly consists of many parts, such as cantilever roadheaders, reloaders, conveyors, etc., through these parts. Cooperate with each other to complete the entire excavation activity. Excavation roadways in existing coal mines are mostly constructed by fully-mechanized excavators, and the fully-mechanized excavator frequently extends the belt head-on. Due to the heavy weight of the buffer tail of the existing fully-mechanized excavator, it is difficult to pull and transport the buffer tail, which consumes a lot of man-hours, and...
