Description
Technical Field
The utility model relates to a colliery is advanced to protect group, especially a colliery is advanced to protect group with stabbing leg ware.
Background
Need the canopy frame to strut in the tunnelling tunnel in the colliery, need protect the group in advance when the canopy frame, stab the in-process of canopy leg at colliery manpower canopy frame, the canopy leg easily receives external force to influence to take place to incline and causes the injury to the human body, and work efficiency is low, and danger coefficient is big.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem and provides a colliery is advanced to protect group with stabbing leg ware, improves the security.
The utility model provides a technical scheme that its technical problem adopted is:
a leg poking device for a coal mine advanced side protection comprises a supporting rod, wherein one end of the supporting rod is fixedly connected with an arc-shaped first clamping support, a first sleeve is sleeved on the supporting rod, one end, far away from the first clamping support, of the first sleeve is fixedly connected with a second clamping support, and the first sleeve at one end of the second clamping support is provided with a radial adjusting bolt; the second sleeve is sleeved on the first sleeve and fixedly connected with a third clamping support, and the second sleeve is provided with an adjusting bolt; one side that the second card held in the palm is equipped with tangential first otic placode, and first otic placode and second card hold in the palm the setting that staggers, and one side that the third card held in the palm is equipped with tangential second otic placode, and second otic placode and third card hold in the palm the setting that staggers.
Adopt above-mentioned technical scheme the utility model discloses compare with prior art, beneficial effect is:
simple structure, with low costs, convenient operation, factor of safety is higher, avoids manpower in the past to erect the canopy and stabs the leg in-process and cause the injury to operating personnel, ensures operation safety.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure, a support rod 1; a first card holder 2; a first sleeve 3; a first ear plate 4; a second card holder 5; a second sleeve 6; a third card holder 7; a second ear plate 8; the bolt 9 is adjusted.
Detailed Description
The present invention will be further described in detail with reference to the accompanying drawings and examples.
Referring to fig. 1, the embodiment is a leg poking device for a coal mine leading edge protection, which is composed of a support rod 1, a first sleeve 3, a second sleeve 6 and the like. The support rod 1 is a round tube, and the circumferential surface of one end of the support rod 1 is welded with an arc-shaped first clamping support 2. First sleeve pipe 3 suit is on bracing piece 1, and first sleeve pipe 3 keeps away from the first card and holds in the palm curved second card of 2 one ends and hold in the palm 5, and the first sleeve pipe 3 welding tangential first otic placode 4 of 5 one sides are held in the palm to the second card, and the setting of staggering of second card support 5 and first otic placode 4. One end of the second clamping support 5 of the first sleeve 3 is provided with two radial adjusting bolts 9. The second sleeve 6 is sleeved on the first sleeve 3, the length of the second sleeve 6 is smaller than that of the first sleeve 3, the circumferential surface of the second sleeve 6 is welded with an arc-shaped third clamping support 7, the second sleeve 6 on one side of the third clamping support 7 is welded with a tangential second ear plate 8, the third clamping support 7 and the second ear plate 8 are arranged in a staggered mode, and the second sleeve 6 is provided with two radial adjusting bolts 9. The first card support 2, the second card support 5 and the third card support 7 are arranged in the same line when in use.
The utility model discloses utilize the card to hold in the palm to fix on two rack shed legs behind the heading face, bracing piece 1 can stretch out and draw back for first sleeve 3 and second sleeve 6, and first sleeve 3 and second sleeve 6 are according to the distance adjustment between the shed leg, and first card holds in the palm 2, second card and holds in the palm 5 and the third card and hold in the palm the distance between 7 and to adjust, and the adjustment back is fastened through adjusting bolt 9, holds in the palm the fixed support shed leg that newly erects of head with the card to realize protecting group in advance. The anchor rod is installed in the connecting hole of first otic placode 4 and second otic placode 8, prevents to stab the leg ware and drops, makes to stab the leg ware fixed firm, increases stability, increases the security.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all structural equivalents made by using the contents of the specification and drawings are included in the scope of the present invention.
