Abstract
The utility model discloses a hydraulic support. The hydraulic support comprises top beams, bases and jack stand columns, wherein an inverted-frustum-shaped column cap is arranged on the lower surface of each top beam, a spherical column shoe is arranged in each base, the jack stand columns are connected to the spherical column shoes, an adjusting rod is connected between each jack stand column and a corresponding inverted-frustum-shaped column cap, a pressure alarm device is arranged on the upper surface of each top beam, and each pressure alarm device is formed by connection of a power supply, a buzzer and a pressure sensor through a wire. The hydraulic support has the advantages of being low in manufacturing cost, economical, practical, convenient to transport, install and dismantle, well adaptable to roadway deformation, high in supporting strength, good in roadway reinforcing and supporting effect, and capable of achieving automatic alarm for prompt when pressure almost reaches the limit of the pressure which can be borne by the support so that workers can deal with the problem in time.
Description
Technical field
The utility model relates to mechanical equipment technical field, relates in particular to a kind of hydraulic support.
Background technology
The daily mine pressure of bump mine is large, and roadway deformation is serious, when bump occurs, often tunnel is produced to considerable damage, cause crush, base plate is heaved etc., harm staff safety, destruction work equipment, bring about great losses.At present, the monomer supporting that home and abroad colliery is used mostly is hydraulic prop, and monomer hydraulic bracket is all used the piston type know-why like this, and when support runs into working resistance, oil cylinder may produce elastic expansion.When the pressure born when hydraulic prop reaches the pressure limit that support bears, easily cause the cylinder body spalling, cause tunnel to collapse and personnel casualty accidents.
The utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides the hydraulic support of a kind of dual support, automatic alarm.
The technical scheme that the utility model adopts is: a kind of hydraulic support, comprise back timber, base and jack column, be provided with inversed taper platform shape cap below back timber, be provided with spherical post footwear in base, be connected with the jack column on spherical post footwear, be connected with adjusting rod between jack column and inversed taper platform shape cap, above described back timber, be provided with pressure warning unit, described pressure warning unit is that power supply, buzzer and pressure sensor wire are connected.
As preferably, described hydraulic support comprises that left and right sub-stent connects by connecting rod.
Compared with prior art, the beneficial effects of the utility model are: cost is low, economical and practical, the transportation assembling and disassembling is convenient, for the roadway deformation strong adaptability, supporting intensity is large, supporting effect is strengthened in tunnel good, can carry out the automatic alarm prompting when pressure reaches the pressure limit that it bears soon, the staff can process in time.
The accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structure chart of the present utility model.
The specific embodiment
In order more clearly to understand the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further illustrated.
A kind of hydraulic support as shown in Figure 1, comprise a left side, parting support on the right side connects by connecting rod 7, sub-stent comprises back timber 1, base 3 and jack column 21, 22, be provided with inversed taper platform shape cap 5 below back timber, be provided with spherical post footwear 6 in base 3, be connected with jack column 21 on spherical post footwear 6, 22, be connected with adjusting rod 4 between jack column 21 and inversed taper platform shape cap 5, be provided with pressure warning unit 8 above described back timber 1, described pressure warning unit 8 is power supply, buzzer is connected with the pressure sensor wire, when reaching the pressure limit that it bears soon, pressure can carry out the automatic alarm prompting, the staff can process in time, described hydraulic support comprises a left side, parting support on the right side connects by connecting rod, increase supporting intensity.
The above is only better embodiment of the present utility model, and the equivalence of doing according to the described structure of the utility model patent claim, feature and principle therefore all changes or modifies, and is included in the utility model patent claim.
