Embodiment Construction

[0035] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0036] An embodiment of the front probe frame for temporary support of the present invention is as Figure 1~Figure 3 As shown, it is a "two-wing type" curved front probe frame, including a main support frame 10, an auxiliary support frame 20 and a front probe frame support structure. The front probe frame support structure includes an upright column 41 connected to the lower part of the support beam on the top surface of the roadway, It also includes a diagonal brace 42 connected between the upright column 41 and the support beam on the top surface of the roadway. The entire front probe frame is mainly welded by steel pipes, the material cost is low, and the manufacture is convenient.

[0037]It is defined that the front probe frame has a depth direction consistent with the extension direction of the roadway and a transverse direction consistent with t...

Abstract

The invention relates to a forward exploring frame used for temporary supporting and a temporary supporting device using the forward exploring frame. According to the forward exploring frame used for temporary supporting, the forward exploring frame is defined to have a depth direction consistent with the extending direction of a roadway and a transverse direction consistent with the width direction of the section of the roadway during use; two or more roadway top face supporting beams are arranged on the forward exploring frame in the depth direction and / or two or more roadway top face supporting beams are arranged on the forward exploring frame in the transverse direction; and the forward exploring frame further comprises forward exploring frame supporting structures connected with at least two roadway top face supporting beams at the same time. The two or more roadway top face supporting beams can be supported at the same time through the forward exploring frame supporting structures, compared with the form of a forward exploring beam or a single hydraulic prop in the prior art, at least half of the workload can be reduced, and the work efficiency is better improved.

Description

technical field [0001] The invention relates to a front probe frame for temporary support and a temporary support device using the front probe frame. Background technique [0002] The roadway section of coal mine rock roadway is a straight wall and semi-circular arch, and the permanent support method is "anchor mesh + anchor cable" support. After the blasting operation, the exposed roadway needs to be permanently supported. Before permanent support, in order to prevent empty During the jacking operation, the rock collapse of the roof endangers the personal safety of the workers, and reliable temporary support is required to protect the workers. Although the existing hydraulic support can play a good supporting effect, it is expensive, poor in mobility, and limited in application. [0003] At present, the temporary support is generally the front beam support. For example, the authorized announcement number is the background technology part of the Chinese patent CN2656637Y. ...
