Problems solved by technology

[0002] Sewage tanks for sewage discharge need to be set up underground in mines. Sewage tanks are excavated and processed by common crawler-type slotting machines. Usually, the width of the sections that need to be excavated underground is different, and then sewage tanks of different widths need to be excavated. The current crawler-type slotting The machine cannot adjust the slotting width, and when excavating underground, it is difficult to determine the porosity of the ground, and the use of existing excavation equipment is prone to safety hazards of landslides;

Embodiment 1

[0031] see Figure 1-5 , an adjustable construction device for digging underground mines, including a chain 1 and a scraper 2. In the prior art, the chain 1 is a fixed chain on a crawler belt, and the scraper 2 is arranged on the outer periphery of the chain 1 and is evenly distributed. In this embodiment, the two adjacent hinges on the chain 1 are all fixedly connected with the positioning plate 12 and the adjusting plate 13 through the movable connecting frame 11, and the positioning plate 12 and the adjusting plate 13 are distributed alternately; One side is fixedly provided with a rotary fixed shaft 121, the number of the scraper 2 is two and one end is connected with the rotary fixed shaft 121 in rotation, the side of the adjustment plate 13 away from the chain 1 is provided with a slider 131, one of the sliders 131 The sides are respectively connected to one side of the two scrapers 2 by two connecting rods 1311. When the slider 131 slides toward the direction of the pos...

Embodiment 2

[0033] see Image 6The difference from Example 1 is that a blade 4 is provided through one side of the scraper 2, and the blade 4 and the scraper 2 are vertically distributed. There are obstacles such as cement and gravel in the interior, which will not only increase the slotting resistance and reduce the service life, but also seriously affect the balance of the entire slotting equipment. By setting the blade plate 4 on the working surface of the scraper 2; the blade plate The blade edge on 4 faces the direction of movement of the scraper 2, which is convenient to squeeze into and cut obstacles, and reduce the resistance of digging; preferably, the rotary fixed shaft 121 is provided with an insertion rod 1211, and the axis of the insertion rod 1211 and The angle bisectors of the two scrapers 2 coincide and are elastically slidably connected to the rotary fixed shaft 121, and a tension spring can be sleeved on the insertion rod 1211. The plate 4 and the scraper 2 are rotation...

Abstract

The invention discloses an adjustable construction device for mining underground grooving. The adjustable construction device comprises a chain and scraping plates. According to the device, the two adjacent hinged positions of the chain are fixedly connected with positioning plates and adjusting plates through movable connecting frames, the positioning plates are rotationally connected with the two scraping plates, the adjusting plates are provided with sliding blocks and connecting rods for adjusting the included angles of the two scraping plates, the sliding blocks slide back and forth to control the included angles of the two scraping plates, when the included angles are decreased, the width of a sewage tank is small, and when the included angles are increased, the width of the sewage tank is large; and an adjusting flexible shaft is arranged on the periphery of the chain, is of a closed-loop structure and is connected with the sliding blocks, a groove-shaped frame is arranged on one side of one adjusting plate, an adjusting sleeve is arranged in the groove-shaped frame, the adjusting sleeve is elastically connected with the local position of the adjusting flexible shaft throughan extrusion spring, movement of the adjusting flexible shaft relative to the chain can be controlled by rotating the adjusting sleeve, then movement of the sliding blocks can be controlled, and therefore the grooving width adjusting function is achieved.

Description

technical field [0001] The invention relates to the technical field of underground trenching in mines, in particular to an adjustable construction device for underground trenching in mines. Background technique [0002] Sewage tanks for sewage discharge need to be set up underground in mines. Sewage tanks are excavated and processed by common crawler-type slotting machines. Usually, the width of the sections that need to be excavated underground is different, and then sewage tanks of different widths need to be excavated. The current crawler-type slotting The machine cannot adjust the slotting width, and when excavating underground, it is difficult to determine the porosity of the ground, and the use of existing excavation equipment is prone to safety hazards of landslides; [0003] For this reason, there is an urgent need for a slotting construction device that can adjust the slotting width and avoid the hidden danger of landslides. Contents of the invention [0004] The...
