Abstract
The utility model discloses a vehicle pressing pillar toppling prevention device for a coal mine drilling rig. The vehicle pressing pillar toppling prevention device for the coal mine drilling rig comprises a chain connection tray and safety ropes which are connected on the chain connection tray. The chain connection tray is provided with a central hole, and the periphery of the chain connection tray is provided with four through holes in a symmetry mode. Each of the through holes is connected with one end of one safety rope, and the other end of each of the safety ropes is connected with a safety lock buckle. The vehicle pressing pillar toppling prevention device for the coal mine drilling rig is simple in structure, convenient to carry, and easy to operate and firm in fixation when connected with a vehicle pressing pillar of the drilling rig. Besides, the vehicle pressing pillar toppling prevention device not only can guarantee construction safety but also meets standards of drilling construction.
Description
Technical field
The utility model belongs to a kind of auxiliary device in the machinery, is specifically related to a kind of coal mine drilling machine post tilting prevention device of delaying unloading.
Background technique
Under the coal mine during drilling machine construction, must use four posts of delaying unloading such as hydraulic monomer to be retractable to the underworkings top board pushes down rig, the about 50kg of post weight because a rig is delayed unloading, if rig occurs loosening in work progress and topples over, very easily injure the workmen by a crashing object, so before drilling machine construction, must use rope that the rig post of delaying unloading is connected with back anchor pole or anchor cable, the unlikely workmen of injuring by a crashing object when toppling over to guarantee delaying unloading rig post is loosening.The multiplex rope made of hemp in existing down-hole is connected the rig post of delaying unloading with back anchor pole or anchor cable, but this attended operation is loaded down with trivial details, and it is not firm to fix, and can not guarantee safety fully, does not meet again the standard of drilling operation.
The model utility content
The technical problems to be solved in the utility model provides a kind of safe coal mine drilling machine easy to use, firm post tilting prevention device of delaying unloading.
For solving the problems of the technologies described above, a kind of coal mine drilling machine of the present utility model post tilting prevention device of delaying unloading, comprise the link pallet and be connected to the safety rope that links on the pallet, it is characterized in that: the link pallet is provided with center hole, be arranged with four through holes around the link pallet, through hole is connected with an end of safety rope, and the other end of safety rope is connected with the insurance snap close.
For making safety rope and linking pallet and more firmly be connected, the bending two ends of safety rope forms sealing ring, and the sealing ring of safety rope one end is connected with through hole, the sealing ring of the safety rope the other end with insure snap close and be connected.
Above-mentioned safety rope is preferably high strength fibre rope or wire rope.
Compared with prior art, the beneficial effect that the utlity model has is:
1, the utility model is made of link pallet and four safety ropes, and is simple in structure, be easy to carry, with rig delay unloading operate when post is connected simple and easy.
2, the utility model is reasonable in design, is fixed on the back anchor pole by center hole, symmetrically arranged four safety rope uniform stresseds, and fixation can guarantee safety, meets again the standard of drilling operation.
3, the utility model fabricating cost is cheap, is easy to promote.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the delay unloading structural representation of post tilting prevention device of a kind of coal mine drilling machine of the utility model.
Embodiment
As shown in Figure 1, a kind of coal mine drilling machine post tilting prevention device of delaying unloading, comprise link pallet 1 and be connected to the safety rope 4 that links on the pallet 1, link pallet 1 is provided with center hole 2, be arranged with four through holes 3 around the link pallet 1, through hole 3 is connected with an end of safety rope 4, and the other end of safety rope 4 is connected with insurance snap close 6.The bending two ends of safety rope 4 forms sealing ring 5, and the sealing ring 5 of safety rope 4 one ends is connected with through hole 3, and the sealing ring 5 of safety rope 4 the other ends is connected with insurance snap close 6.
During use, the utility model is fixed on back anchor pole or the anchor cable by center hole 2 with anchor nut or anchor cable lock, safety rope 4 and rig delayed unloading that post twines and tension after, buckle with insurance snap close 6 respectively again, post is loosening can firmly to be tacked the post of delaying unloading when toppling over when rig is delayed unloading, guaranteeing that it is unlikely to topple over injures the workmen by a crashing object, and both firm safety meets again the standard of drilling operation.
