Description

Technical Field

[0001] The utility model belongs to the field of tunnel rescue, and in particular relates to a stroke collision warning device for a power head of a large-caliber horizontal rescue drill. Background Art

[0002] FS120-CZ is a large-caliber horizontal rescue drill specially designed for rapid drilling of escape passages in the event of tunnel collapse.

[0003] Because the FS120-CZ large-diameter horizontal rescue drill has no early warning and limit control during operation, and the operator cannot directly see the position of the power head and can only judge by the position of the drill rod, the two power heads are prone to collision during operation. The collision pressure reaches 35MPa, which can easily cause damage to the power head.

[0004] Therefore, we propose a large-caliber horizontal rescue drill power head stroke collision warning device to solve the above problems. Utility Model Content

[0005] Aiming at the problem that the FS120-CZ large-caliber horizontal rescue drill has no warning and limit control during operation, and the operator cannot directly see the position of the power head and can only judge by the position of the drill rod, the two power heads are prone to collision during operation, which can easily lead to damage to the power heads. The utility model provides a large-caliber horizontal rescue drill power head stroke collision warning device.

[0006] The utility model solves the technical problem by adopting a solution: a large-caliber horizontal rescue drilling rig power head travel collision warning device, comprising a rail piece, an alarm, a fixing plate and two bolts, the rail piece is horizontally provided with a strip groove, and the arc end of the rail piece is installed with a travel electric shock switch for contacting with the power head;

[0007] The bolt passes through the strip groove and is installed on the outer shell. A rolling piece is arranged on the bolt. The rolling piece contacts the track piece so that the track piece can slide laterally.

[0008] The fixing plate is welded on the rail plate and arranged close to one of the bolts, and at least one spring is installed between the fixing plate and the other bolt;

[0009] The travel contact switch is connected to the alarm.

[0010] Preferably, the rolling element comprises two washers and two nuts, the two washers are respectively located at the front and rear sides of the track piece, the two nuts are threadedly connected to the bolts, and are respectively arranged corresponding to the two washers.

[0011] Preferably, the rolling element is a groove wheel mounted on the bolt.

[0012] Preferably, there are two springs.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. During the movement of one power head on one side of the present utility model, the travel contact switch is touched, and the travel contact switch emits a signal and transmits it to the alarm. 10 cm before the two power heads of the FS120-CZ large-caliber horizontal drilling rig collide, the alarm emits an audible and visual alarm for early warning to alert the operator, thereby avoiding the collision of the two power heads during operation and playing a protective role for the power heads.

[0019] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0020] Please refer to Figures 1 - 3 , the present utility model provides a technical solution for a travel collision early warning device for the power head of a large-caliber horizontal rescue drilling rig:

[0021] Embodiment 1:

[0022] As shown in Figures 1 - 3 , it includes a rail piece 1, an alarm, a fixing piece 51 and two bolts 4. A strip-shaped groove 2 is transversely formed on the rail piece 1, and a travel contact switch 6 for contacting the power head 7 is installed at the arc end of the rail piece 1.

[0023] The bolts 4 pass through the strip-shaped groove 2 and are installed on the outer housing 8. Rolling members are provided on the bolts 4. The rolling members include two gaskets 31 and two nuts 32. The two gaskets 31 are respectively located on the front and rear sides of the rail piece 1 to limit the rail piece 1 to ensure the stability of the rail piece 1 during horizontal sliding.

[0024] The two nuts 32 are threadedly connected to the bolts 4 and are respectively arranged corresponding to the two gaskets 31. The positions of the gaskets 31 are fixed by the nuts 32 to prevent the gaskets 31 from shifting and ensure the limiting effect on the rail piece 1.

[0025] The fixing piece 51 is welded and installed on the rail piece 1 and is arranged close to one of the bolts 4. At least one spring 52 is installed between the fixing piece 51 and the other bolt 4. In this embodiment, the number of springs 52 is two. By arranging the springs 52, after the power head 7 is reset, under the action of the springs 52, the rail piece 1 is pulled to move and reset.

[0026] The travel contact switch 6 is connected to the alarm. During the movement of one side of the power head 7, the travel contact switch 6 is touched. The travel contact switch 6 emits a signal and transmits it to the alarm. 10 cm before the two power heads 7 of the FS120-CZ large-bore horizontal drill collide, the alarm emits an audible and visual alarm for early warning to alert the operator, so as to avoid the collision of the two power heads 7 during operation and protect the power heads 7.

[0027] Embodiment 2:

[0028] On the basis of Embodiment 1, the difference is as follows. The rolling element is a grooved wheel sleeved on the bolt 4.
