Problems solved by technology

Although this kind of support structure solves the difficulty of transporting the support column, because the support method has not changed, that is, the upper and lower support top structures are still used, so this type of support does not solve the fundamental problem of the stability of the drilling rig during construction.

Embodiment Construction

[0020] Referring to FIG. 3 , the front and rear support structure of the drilling rig involved in the present invention is mainly composed of three parts: a front support 1 , a propulsion frame 2 and a rear support assembly 3 . The front support 1 is horizontally connected to the front of the propelling frame 2, and the rear support assembly 3 is connected to the rear of the propelling frame 2 horizontally and backward. The rear support assembly 3 is composed of an oil cylinder I3.1 and a rear support 3.2. Back support 3.2 links to each other with the piston rod of oil cylinder I3.1.

[0021] see Figure 4 ~7. The connection between the front support 1 and the propulsion frame 2 can be divided into two types: fixed connection and telescopic adjustment connection:

[0022] 1. The front support 1 is fixedly connected with the propulsion frame 2

[0023] The fixed connection between the front support 1 and the propulsion frame 2 can be divided into two types: end face fixed con...

Abstract

The invention relates to a drillmobile front and rear support structure which is mainly used for the front and rear support of a drillmobile when drilling in the coal mine laneway operation. The support structure comprises a propelling bracket (2), a front support (1) and a rear support component (3), wherein, the front support (1) is connected with the front part of the propelling bracket (2) horizontally and forwards, the rear support component (3) is connected with the rear part of the propelling bracket (2) horizontally and backwards, and the rear support component (3) comprises an oil cylinder I(3.1) and a rear support (3.2) which is connected with a cylinder rod of the oil cylinder I(3.1). The support structure has convenient transportation, short operation time and stable support.

Description

technical field [0001] The invention relates to a front and rear support structure of a drilling car, which is mainly used for the front and rear support of the drilling car for drilling holes in coal mine roadway operations. It belongs to the technical field of mining machinery. Background technique [0002] At present, the support structures used to fix the drilling rig during roadway operations mainly include the upper and lower supports of a single pillar and the upper and lower supports of the column that comes with the truck. The upper and lower support structure of the former single pillar is shown in Figure 1. After the drilling rig is adjusted to the construction position, the single pillar is used to support the top 4.2 of the roadway up and down to fix the drilling rig. The pillars of this support structure are about 80-90 kg each, and two people are required to carry them. And as the modern coal seam is getting higher and higher, the pillars used are just getti...
