Abstract
本实用新型的张拉自锁防滑锚具，包括设在锚索上的金属网、钢带、托盘、锚具外套、夹片、活塞杆和油缸，锚具外套下端部开有环行凹槽；所述油缸上设有与其连为一体的法兰，法兰上设有铰座，铰座通过销钉铰接，有与锚具外套的环行凹槽相嵌的钩子。与现有技术相比，能防止锚索承载后期锚具滑移，实现锚索锚具的定点锁紧，适用于煤矿巷道、隧道、硐室的锚索支护。其结构简单，操作安全可靠，使用方便，具有广泛的实用性。
The tension self-locking anti-skid anchor of the present utility model includes a metal mesh, a steel belt, a tray, an anchor coat, a clip, a piston rod and an oil cylinder arranged on the anchor cable, and the lower end of the anchor coat is provided with a circular groove; The oil cylinder is provided with a flange connected with it as a whole, and the flange is provided with a hinge seat, which is hinged by a pin and has a hook embedded in the annular groove of the anchor coat. Compared with the prior art, it can prevent the anchor cable from slipping in the later stage of anchorage, realize fixed-point locking of the anchor cable anchorage, and is suitable for anchor cable support in coal mine roadways, tunnels, and chambers. The utility model has the advantages of simple structure, safe and reliable operation, convenient use and wide practicability.
Description
Technical field
The utility model relates to stretch-draw self-locking skidproof ground tackle, is particularly useful for the single hole cable bolting of coal mine roadway, tunnel, chamber.
Technical background
Coal mine roadway, Rail Highway tunnel, chamber support adopt the supporting of anchor rete cord in a large number at present.A large amount of engineering practices show that when country rock was soft, the unsuitable stretch-draw of anchor cable ground tackle was tight.In addition, influenced by human factor, the anchor cable ground tackle does not have stretch-draw tight in many cases, causes anchor cable in the later stage load bearing process, the ground tackle sliding phenomenon often occurs.
The utility model content
According to the problem that prior art exists, the purpose of this utility model provides a kind of simple in structure, safe and reliable, easy to use, effective stretch-draw self-locking skidproof ground tackle.
For achieving the above object, stretch-draw self-locking skidproof ground tackle of the present utility model comprises the wire lath, steel band, pallet, ground tackle overcoat, intermediate plate, piston rod and the oil cylinder that are located on the anchor cable, and described ground tackle overcoat bottom has annular recess; Described oil cylinder is provided with the flange that is connected as a single entity with it, and flange is provided with free bearing, and free bearing is hinged with and the annular recess of the ground tackle overcoat hook of embedding mutually by pin.
Described free bearing and the hook that is located on the flange can be three, also can be four; Described flange and oil cylinder are welded as a whole; Described free bearing is welded on the flange.
The beneficial effects of the utility model are:
1, be difficult for tensioning in the first stretch-draw of the weak anchor cable of rock mass, the initial stage anchor cable lockset of perhaps constructing does not have under the situation of tensioning, can prevent anchor cable carrying later stage ground tackle slippage problem;
2, in the unsuitable tensioning of anchor cable construction initial stage, and the anchor cable carrying later stage prevents under the situation of ground tackle slippage again, can realize the fixed point locking of anchor cable ground tackle, both protected original supporting the supporting initial stage not by artificial destruction, prevent supporting carrying later stage yield failure again.
Description of drawings
Fig. 1 is the utility model stretch-draw self-locking skidproof ground tackle structure A-A sectional view.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1-anchor cable, 2-country rock, 3-wire lath, 4-steel band, 5-pallet, 6-ground tackle overcoat, 7-intermediate plate, 8-hook, 9-piston rod, 10-pin, 11-free bearing, 12-flange, 13-oil cylinder.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Fig. 1 is shown in Figure 2, stretch-draw self-locking skidproof ground tackle of the present utility model, the anchor cable 1 that passes country rock 2 is provided with wire lath 3, wire lath 3 has steel band 4, steel band 4 has pallet 5, pallet 5 has ground tackle overcoat 6, and the middle part of ground tackle overcoat 6 is provided with wedge shape intermediate plate 7, and the bottom of ground tackle overcoat 6 has annular recess; Ground tackle overcoat 6 has oil cylinder 13, and the piston rod 9 of oil cylinder 13 is set on the anchor cable 1.Oil cylinder 13 is provided with the flange 12 that is welded as a whole with it, is welded with 11, three free bearings 11 of three free bearings on the flange 12 and is hinged with hook 8 by pin 10, the annular recess embedding mutually of hook 8 and ground tackle overcoat 6.
The course of work: at first start oil cylinder 13, promote ground tackle overcoat 6 by piston rod 9 and compress pallet 5, adjust piston rod 9 positions, the hook 8 that is located on the flange 12 is embedded in the groove of ground tackle overcoat 6 bottoms, by piston rod 9 pushing wedge shape intermediate plates 7, implement stretch-draw then, wait to reach set numerical value after, stop stretch-draw, promptly finish support work the country rock top board.
