Embodiment Construction

[0010] A cantilever-type front probe beam device, characterized in that it includes a fixed splint, a locking bolt, a nut, an I-beam top beam, a front probe beam, pins, a fixing hole and an adjustment hole, and two clamping slots for the fixed splint The lower edge of the I-beam top beam is fixed on the I-beam top beam by locking bolts and nuts. The front probe beam passes through the inner groove of the fixed splint, and passes through the adjustment hole on the front probe beam and the fixing hole on the fixed splint. Cooperate, and fix the probe beam through pins.

[0011] Uniform adjustment holes are arranged on the probe beam of the present invention.

[0012] The working principle of the present invention is as follows: the present invention utilizes the groove of the fixed splint to be stuck on the lower edge of the top beam bracket, and is firmly fixed on the top beam by locking bolts, and the front probe beam is fixed on the I-beam top beam to fix the splint device 1...

Abstract

The invention discloses a suspension girder type forepoling bar device. The suspension girder type forepoling bar device is characterized by comprising fixing clamping plates, locking bolts, nuts, anI-shaped steel top beam, a forepoling bar, pins, fixing holes and adjusting holes, wherein clamping grooves of the two fixing clamping plates are clamped to the lower edge of the I-shaped steel top beam, and are fixed on the I-shaped steel top beam through the locking bolts and the nuts; and the forepoling bar penetrates through the inner grooves of the fixing clamping plates and is matched with the fixing holes in the fixing clamping plates through the adjusting holes in the front probe beam, and the forepoling bar is fixed through the pins. The suspension girder type forepoling bar has the characteristics of being safe and reliable in performance, convenient and rapid to install, capable of automatically adjusting the front, rear, left and right positions during mounting, suitable for advanced exploration temporary supporting during tunneling of a shed supporting roadway, and capable of being repeatedly used.

Description

technical field [0001] The invention relates to the field of temporary support for mine roadway excavation, in particular to a suspension beam type front probe beam device. Background technique [0002] During the tunneling of the mine trellis tunnel, it is necessary to add a temporary support device for the front probe beam. In production, the steel pipe or channel steel is often bound on the I-beam top beam for the front probe support. The operation is cumbersome, the key is that the safety factor is small, it is inconvenient to use, and the materials used for binding cannot be reused for a long time, which is unsafe and economical, and a lot of manpower and material resources are wasted. Contents of the invention [0003] The present invention just provides a kind of cantilever type front probe beam device. [0004] The technical solution of the present invention is: a cantilever-type front probe beam device, which is characterized in that it includes a fixed splint, a...
