Abstract
The utility model provides a tunnel monomer pillar pulls out post device of relating to tunnel appurtenance field, the device be equipped with at least two independent, nevertheless relative one side all is equipped with circular -arc sunken base, and every base all is fixed with a hydraulic pressure post that is equipped with hydraulic control system, the item terminal pair of two hydraulic pressure posts answer fixed connection with a back timber, the both sides face carried on the back mutually of back timber all be fixed with a chain at least, the bottom of these chains correspond fixed connection no. 1 be equipped with the friction fill up with the clamp of quick lock ring device, the clamp correspondence be located between the hydraulic pressure post, the device can be effectual the reduction workman the operation degree of difficulty with the security when retrieving the monomer pillar improves.
Description
[technical field]
The utility model relates to mining tunnel appurtenance field, especially relates to a kind ofly pulling out column device for what reclaim individual prop in tunnel.
[background technology]
Known, mining tunnel individual prop is a kind of small investment, instant effect, support apparatus that flexibility is large, it not only can support the use with hardwares such as metal hinge top beams, adopt for high-grade conventional mining, big gun, the end support of fully-mechanized mining working, but also can to use as a post or other temporary supporting separately; But the structure by individual prop limits, its floor pressure ratio Air holder when applying is comparatively large, and manifesting gradually therefore along with ore deposit pressure, individual prop is very easily absorbed in base plate, and sinks deeper and deeper, and finally can become an anchor stud; Now, for avoiding causing economic loss because cannot individual prop be reclaimed, usually drawing hoist will be used to pull these individual props to reclaim, but due to the rope hook rigging of winch and the hinge Suo Wenti of individual prop, the reasons such as the handle strength at such as hinge rope place or hinge Suo Li deficiency easily cause rigging Slip Hook or fly the phenomenons such as hook, thus not only add the operation easier of workman, but also individual prop can be caused to be subject to permanent lesion, even also therefore can there is the problems such as security incident.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of tunnel individual prop and pulling out column device, the operation easier that described device can effectively reduce workman and the safety improved when reclaiming individual prop.
For achieving the above object, the utility model adopts following technical scheme:
A kind of tunnel individual prop pulls out column device, and described device is at least provided with two independently, and relative one side is equipped with the base of arc-shaped depression, and each base is all fixed with the hydraulic column that is provided with hydraulic control system; The top correspondence of two described hydraulic columns is fixedly connected with same back timber; The opposing two sides of described back timber are all at least fixed with a chain, and the bottom correspondence of these chains is fixedly connected with a clip; Described clip is corresponding between hydraulic column.
Further, described base top surface center is fixed with the sleeve for firm clamping hydraulic column, and sleeve outer wall is provided with support.
Further, described chain is corresponding is cross-shaped with hydraulic column.
Further, described clip is provided with friction pad and Quick tightening device.
Further, described back timber side is fixed with four symmetrical chains.
Owing to adopting technical scheme as above, the utility model has following beneficial effect:
Tunnel described in the utility model individual prop pulls out column device and adopts hydraulic control architectures light flexibly, and not only structure is simple for it, be convenient to manufacture, and the power of recovery is large, is easy to use; Described device not only can effectively reduce operation easier and the labour intensity of workman, but also safe retrieving individual prop under the prerequisite of workman's not Misuse drawing hoist can be ensured, namely described device can reach when pulling and pulling out post effectively avoids individual prop to suffer damage, save corresponding economic loss, avoid the object that personal injury phenomenon occurs.

[detailed description of the invention]
Can explain the present invention in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
Tunnel individual prop by reference to the accompanying drawings described in 1 ~ 3 pulls out column device, described device is provided with two independently, and in opposite directions and right one side is equipped with the circular arc base 1 of depression, namely two bases 1 compactly by symmetrical sunk structure can be placed on the both sides needing the individual prop 9 extracted; Simultaneously, each base 1 is all fixed with the hydraulic column 3 that is provided with hydraulic control system 2, namely the hydraulic column 3 be fixed on two bases 1 can rely on hydraulic control system 2 to carry out corresponding synchronization telescope action, thus has carried out the operation of lift individual prop 9 with this; For ease of fixer compression leg 3, one can being fixedly installed at the end face center of base 1 for the sleeve 7 of the firm clamping hydraulic column 3 that coincide, for gaining in strength, multiple support 8 can being set uniformly at the outer wall of sleeve 7;
The top correspondence of two described hydraulic columns 3 is fixed on same back timber 4, and opposing two sides of back timber 4 are at least fixed with a chain 5, the bottom correspondence of these chains 5 is fixedly connected with the clip 6 that is provided with friction pad and Quick tightening device, and namely clip 6 firmly can be fixed on the outer wall of individual prop 9 by rubbing cushion and Quick tightening device; Described clip 6 correspondence is between hydraulic column 3, and do not contact with hydraulic column, namely hydraulic column 3 extends upwardly long band and moves back timber 4 and rise, back timber 4 is then synchronously driven by the individual prop 9 of clip 6 lock ring by chain 5, finally reaches the object that will be absorbed in individual prop 9 entirety that base plate becomes anchor stud and extract; For making the dynamics of lift process even, these chains 5 can be set to and two corresponding shapes in right-angled intersection of hydraulic column 3.
Implement tunnel described in the utility model individual prop when pulling out column device, only need will can reduce the symmetrical fixed placement of base 1 of floor pressure ratio Air holder in corresponding individual prop 9 both sides, clip 6 is tightly bound round on the outer cylinder diameter of individual prop 9 again, then just can carry out lift operation by operation hydraulic control system 2, and individual prop 9 is extracted the most at last.
The non-detailed portion of the utility model is prior art, therefore the utility model is not described in detail.
