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

[0053] 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 .

[0054] At least one vibration absorber 73 is arranged radially inside the cavity 725;

[0055] Vibration-absorbing elastic metal 731, the elastic metal 731 uses 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.

[0056] When the idler 7 vibrates under the action of 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 elasticity The metal 731 resonates, absorbs most of the vibration energy of the idler 7 in the resonance, and converts this...

Abstract

The invention discloses a light machine tail buffer device for a coal mine roadheader. The light machine tail buffer device comprises a base, and the two sides of the upper end of the base are fixedlyconnected with hoops correspondingly; the upper ends of the hoops are fixedly connected with I-shaped steel runways, and buffer mechanisms are mounted on the upper surfaces of the I-shaped steel runways; the input ends of the buffer mechanisms are connected with carrier roller frames, and the top ends of the carrier roller frames are fixedly connected with hanging pulleys; and steel wire ropes are wound on the hanging pulleys on the two sides correspondingly, and the common steel wire rope between the hanging pulleys on the two sides is connected with one or more carrier rollers. The haulagedifficulty is lowered, and the construction safety is guaranteed; and in a roadheader roadway, belt extending and buffer machine tail haulage are frequent, when a buffer machine tail is pulled, the roadheader and the buffer machine tail are connected through a chain or an anchor rod, the weight is large, thus the risk that the chain and the anchor rod are broken to hit and injure personnel exists,an existing light buffer machine tail can effectively improve the current situation, the construction safety is guaranteed, and the haulage difficulty is lowered.

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...
