Abstract

The utility model discloses an upper-lower split type body frame of a heading machine, which belongs to the field of coal mine roadway heading equipment, and comprises a lower body frame and an upper seat body, wherein the upper seat body is of an approximately rectangular irregular plate structure; the upper seat body is detachably connected above the lower body frame; the split type body frame is detachably connected to a travelling mechanism of the heading machine. The upper and lower split type body frame structure of the heading machine provided by the utility model is different from the traditional integrally welded type body frame, and the body frame can be disassembled for up and down assembly, so that the defect that the body frame cannot go down a well due to the limitation of the height and the size is avoided. The upper and lower split type body frame is simple in structure assembly, high in reliability and wider in applicable coal mine wellhead size range.

Description

Upper and lower split type body frame of heading machine

Technical Field

The utility model relates to the field of coal mine roadway tunneling equipment, in particular to an upper-lower split type body frame of a tunneling machine.

Background

At present, the development machine is widely applied to various coal mine excavation, and the whole machine mainly comprises a cutting part, a shovel plate part, a body part, a walking part and the like, and all the parts can be disassembled, transported and then assembled for use after being put into a well. The main body frame is usually the largest undetachable structural member of the whole machine, and the situation that the well cannot be normally lowered due to the limitation of the height and the size of the wellhead can occur. An improvement is to divide the body frame into a front body frame and a rear body frame, but this structure does not change the height of the body frame. Therefore, the problem that the large height of the body frame of the heading machine cannot be suitable for a small-size wellhead of a coal mine is very critical.

Disclosure of Invention

The utility model aims to solve the problem that a body frame is too large in height and cannot be suitable for a small-size wellhead of a coal mine, and provides an upper-lower split type body frame of a heading machine.

The technical problems to be solved by the utility model can be implemented by the following technical proposal.

An upper-lower split type body frame of a heading machine comprises a lower body frame and an upper seat body, wherein the upper seat body is of an irregularly-shaped plate structure; the upper seat body is detachably connected above the lower body frame; the split type body frame is detachably connected to a travelling mechanism of the heading machine.

In the above technical solution, preferably the lower body frame is provided with at least one positioning pin hole and at least one threaded hole; the upper seat body is provided with at least one second positioning pin hole and at least one countersunk hole.

In the above technical scheme, preferably, the lower body frame and the upper seat body are assembled and accurately limited through the locating pin.

In the above technical solution, preferably, the lower body frame and the upper base are fastened and connected by an embedded screw.

In the above technical solution, preferably, a groove is provided at the rear portion of the lower body frame, and a spigot is provided at the rear portion of the upper seat body to match with the groove.

The utility model has the following advantages: the upper and lower split type body frame structure of the heading machine is different from the traditional integrally welded type body frame, and the body frame can be disassembled for up and down assembly, so that the defect that the body frame cannot go down a well due to the limitation of the height and the size is avoided. The upper and lower split type body frame is simple in structure assembly, high in reliability and wider in applicable coal mine wellhead size range.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

The utility model discloses an upper-lower split type body frame of a heading machine, which is suitable for the field of coal mine tunnel heading equipment.

In the description of this patent, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the patent and simplify the description, and do not indicate or imply that the devices or elements being referred to must have a particular orientation, be configured and operated in a particular orientation, and are therefore not to be construed as limiting the patent.

In the description of this patent, it should be noted that, unless explicitly stated and limited otherwise, the terms "mounted," "connected," and "disposed" are to be construed broadly, and may be fixedly connected, disposed, detachably connected, disposed, or integrally connected, disposed, for example. The specific meaning of the terms in this patent will be understood by those of ordinary skill in the art as the case may be.

As shown in fig. 1 to 7, the upper and lower split body frame of the tunneling machine consists of a lower body frame 1, an upper seat body 2, a positioning pin 3 and a screw 4. The rear spigot of the upper seat body 2 is in contact fit with the rear groove of the lower body frame 1 to carry out front and rear limiting, and the upper seat body 2 is precisely assembled above the rear of the lower body frame 1 through a locating pin 3 and is connected and fastened through a screw 4. The machining of lower body frame rear portion recess and last pedestal rear portion tang, screw hole and other cooperation sizes all uses the junction surface and the location pinhole of lower body frame and last pedestal as the benchmark to improve assembly precision and structural reliability. The split type body frame is detachably connected to a travelling mechanism of the heading machine.

After the lower body frame 1 and the upper seat body 2 are respectively put down in the well, the lower body frame 1 is assembled on the travelling mechanism through key grooves and bolts according to the traditional assembly mode, and then the upper seat body 2 is assembled on the lower body frame 1. The rear spigot 2-3 of the upper seat body 2 is in contact fit with the rear groove 1-3 of the lower body frame 1 for front and rear limiting, and the upper seat body 2 is precisely assembled above the rear of the lower body frame 1 through the locating pin 3 and is connected and fastened through the screw 4.

The foregoing is merely a preferred embodiment of the present utility model and it should be noted that variations and substitutions will now be apparent to those skilled in the art without departing from the principles of the present utility model, which are also considered to be within the scope of the utility model.
