Problems solved by technology

However, because the space is restricted by objective conditions, the temporary safety protection devices installed are all simple devices. Their structural volume is very small, the temporary safety protection area provided is extremely limited, and the load they can bear is also Very small, it is difficult to meet the needs of temporary safety protection for on-site construction operations
[0005] Some roadheader manufacturers, based on the chassis of the cantilever type horizontal axis roadheader that the cutting part does not swing horizontally, have set up a temporary support top cover or shield, but this temporary safety protection device can only be used for cutting. Provide protection for support operations after the cutting drum, the top cover or shield of the temporary support cannot be retracted or rotated around the horizontal hinge axis, it is difficult to provide temporary safety protection for the permanent support construction work above and in front of the cutting drum

Embodiment 1

[0027] In this embodiment, the chassis of the cantilever-type longitudinal-axis roadheader is used as the chassis, and a telescopic shield and a rotary shield are arranged on the front and upper part of the chassis to provide a wider and longer protection range for personnel working in front of the roadheader chassis, and a higher carrying capacity. The large temporary safety protection ensures that the construction workers get reliable and safe protection for the construction work in front of the roadheader chassis. Such as figure 1 , figure 2 and image 3 Commonly shown is a cantilever type excavation and protection integrated machine, the frame body 202 is connected with the double crawler type running part 201, and the two together form a chassis. The cantilever type longitudinal axis cutting part 100 is arranged on the upper front of the chassis.

[0028] The base 306 is installed above the chassis through a carrying mechanism, which is a significant difference compar...

Embodiment 2

[0035] Such as Figure 4 As shown, this embodiment is a simplified version of Embodiment 1, which removes the swing shield 308 and the swing power device that drives the swing shield 308 to swing.

Embodiment 3

[0037] Such as Figure 5 As shown, this embodiment is another simplified version of Embodiment 1, which removes the telescopic shield 307 and the telescopic power device that drives the telescopic shield 307 to expand and contract in the longitudinal direction, and directly connects the swing shield 308 to the base through the transverse hinge shaft. Seat 306 is hinged.

Abstract

The invention discloses a cantilever type digging and protecting integrated machine. The machine comprises a chassis and a cantilever type cutting part; the base, wherein the base is arranged above the chassis through a bearing mechanism; a telescopic protective cover and / or a swinging shield, wherein the telescopic protective cover is in sliding connection with the base; a telescopic power devicethat is arranged between the base and the telescopic protective cover; the swinging shield is hinged with the telescopic protective cover through a transverse hinge shaft; and a swinging power devicethat is arranged between the swinging shield and the telescopic protective cover. For the ,cantilever type digging and protecting integrated machine, the load carried by the telescopic shield and / orthe rotary shroud is directly transmitted to the chassis via the base and the supporting mechanism, and is completely unaffected by the cantilever cutting portion. Therefore, the telescopic shroud and / or the revolving shroud can provide a wider range of protection for construction workers in front of the chassis of the roadheader. The temporary safety protection with greater carrying capacity ensures that the construction workers can be reliably and safely protected in the construction work ahead of the chassis of the roadheader.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to a cantilever type device integrating the functions of roadheading and airborne temporary support. Background technique [0002] There are two types of cantilever roadheaders: cantilever longitudinal axis roadheader and cantilever transverse axis roadheader. For a long time, the above-mentioned cantilever-type roadheader has been widely used because of its strong adaptability and other advantages. In particular, the cantilever-type longitudinal axis roadheader has been available for more than 70 years, and it is still the main technical equipment for coal mine and coal roadway construction in the world. . [0003] However, there are still many deficiencies in the cantilever roadheader at present, one of which is that when performing permanent support operations during the construction process, there is no ideal airborne temporary support equipment to provide reliable safety p...
