Abstract
On the basis of no changing the structure of an original single column, the utility model is formed by adding a lifting barrel structure, and with the lifting device, the specification of the original single column can be increased by two times. The utility model is suitable for occasions of underground mechanization and top plate support on mining faces and is composed of an upper lifting device which is arranged on the upper end of an active column body and a lower lifting device which is arranged on the bottom of an oil cylinder. According to the actual height of an underground working face and the height of a spare single column, the selection of the specification and the lifting device is decided, so that the reserve of single columns with various specifications and the transportation volume can be reduced, and then the use rate of single columns is increased. The utility model has the advantages of interchange ability and universality.
Description
The utility model relates to a kind of rising device of hydraulic prop.Be applicable to the occasion of down-hole mechanicalization and face roof timbering.
Existing hydraulic prop (hereinafter to be referred as single-column), though it is good with its safety, the efficient height, once investment is benefited for many years and has replaced mine timber and metal friction pillar, but there is following problem: 1, the maximum height of every kind of specification is changeless, totally 11 kinds of specifications from 0.6 meter to 2.8 meters, every kind of specification can only adapt to the face height of this specification, and in the actual mining, because mineral reserve are limited by geological conditions, the height of a work plane also often changes with the geology condition, the maximum height that a kind of specification often occurs is not enough, or surpasses the limit minuent of itself; 2, for satisfying the mining needs, certainly will cause the single-column specification deposit of work plane and the increase of round transport amount, directly influence operating efficiency; 3, few as single-column specification deposit, influence mining benefit will appear losing the ore deposit or damaging single-column by pressure.
For addressing the above problem, the utility model provides a kind of minimizing input, improves the rising device of the hydraulic prop of utilization rate and mining economic benefit.
Fig. 1 is the structural representation that rising device is housed;
Fig. 2 is the structural representation that rising device is housed down.
In conjunction with the accompanying drawings structure of the present utility model and embodiment are described below:
Referring to Fig. 1, former single-column is that the endoporus by top cover 1 directly is enclosed within on the outer garden 4a of cylinder 4 alive, is fixed as one with three elasticity garden tube pins 2.The utility model is by top cover 1, elasticity garden tube pin 2 and increase tube 3 and constitute, top cover 1 is identical with the physical dimension of former single-column top cover, along garden week with 3 elasticity garden tube pins 2 with top cover 1 and the fitting face 3a connection of increasing tube 3 of joining of endoporus cunning is in aggregates with it, increasing tube 3 adopts the welding of silicomanganese steel pipe material to make, also availablely form with material steel casting back car system, increase definite intensity of the height of tube with the maintenance single-column, unaffected being advisable of stability, now be defined as 0.2 meter, generally can be 0.2～0.3 meter.
During use, the top cover 1 of former single-column is screwed off, change this rising device, the endoporus 3b that will increase tube 3 is enclosed within on the outer garden face 4a of cylinder 4 alive, with 3 elasticity garden tube pins 2 this device is fixed on the single-column, can strengthens a specification, for improving reliability, this device can be used for 0.6 meter single-column top to 2.2 meters 9 kinds of specifications and increases, and do not influence the every performance of former single-column, can use easy installation and removal after pulling down by former specification, have and exchange and versatility, can directly exchange in the down-hole.
Referring to Fig. 2, rising device is to increase that tube 6, base 7 connect steel wires 5, base anti-extrusion ring 8 constitutes by being welded on the lower bottom base with lower arcuate surface under the utility model, base 7 is identical with former single column footing physical dimension, connect steel wire 5, base anti-extrusion ring 8 is identical with former single-column also, and the last garden anchor ring 6a that increases tube 6 is welded into a whole with the corresponding garden anchor ring 7a of base 7, increases 6 an employing silicomanganese steel pipe material, also availablely form with material steel casting back car system, it highly is 0.15～0.24 meter.
During use, breakdown connects steel wire 5, and former single column footing 7 is taken off, and changes this rising device down, base 7 is inserted in the endoporus of oil cylinder 9, at base 7, cover upper bed-plate anti-extrusion ring 8 in the respective grooves, in base 7 and oil cylinder 9 respective grooves, connect steel wire 5 on the card, promptly on former specification, increase a specification.Following rising device can repaired the worker-house installing/dismounting, has and exchanges and versatility, can be installed in 0.6 meter single-column oil cylinder bottom to 2.5 meters 10 kinds of specifications and use, and promptly recovers former specification after pulling down.
Install the whole post of rising device and install the whole post of rising device to carry out intensity respectively, stability and seal tightness test all reach ministry standard.
Advantage of the present utility model: 1, adopt this device after, improved the utilization rate of hydraulic prop. Reduce deposit and freight volume, improved operating efficiency, reduced investment, increased economic benefit; 2, because interchangeability and versatility are good, reduced labor strength; 3, simple to operation; 4, simple in structure, easy to manufacture. The utility model has the value of promoting the use of.
Claims (3)
1, a kind of rising device of hydraulic prop, it is characterized in that, by top cover (1), elasticity garden tube pin (2) and increase tube (3) and constitute, along garden week with three elasticity garden tube pins (2) with top cover (1) and be connected in aggregates with a fitting face (3a) that increases tin (3) that top cover endoporus cunning is joined.
2, by the described rising device of claim 1, it is characterized in that, also can be by increase tin (6) that are welded on the lower bottom base, base (7), connect steel wire (5) and be enclosed within base anti-extrusion ring (8) formation in the groove of base (7), the corresponding position (7a) of increasing last garden anchor ring (6a) and the base (7) of tube (6) is welded into a whole, and is provided with in the groove of base (7) to connect steel wire (5) and prepare against when being inserted in oil cylinder, and blocks mutually in the oil cylinder respective grooves.
By claim 1 or 2 described rising devices, it is characterized in that 3, the height that increases tube is 0.2～0.3 meter.
