Abstract

The utility model discloses a suspension oil cylinder, and relates to the technical field of machine manufacturing. The suspension oil cylinder comprises cylinder bodies provided with a plurality of hydraulic cylinders, oil inlet pipes of the cylinder bodies are communicated mutually, and two pistons with the opposite moving directions are arranged in the hydraulic cylinders of the cylinder bodies. One end of each cylinder body is provided with a connecting boss, and the other end of each cylinder body is provided with a groove used for being connected with the connecting boss of another cylinder body in an abutting mode. Every two cylinder bodies are fixedly connected through a connecting screw in the mode that the connecting boss of one cylinder body is inserted into the groove of the other cylinder body. The suspension oil cylinder can solve the problem that an existing oil cylinder body is prone to deformation, distortion, invalidation and damage and cannot meet the building engineering construction or longer and deeper mining working environment requirements, overcomes the defects of expanding agents and explosive used during mining and building engineering construction, and has the advantages of being safe, efficient, environmentally friendly, low in energy consumption and cost, and wide in application range.

Description

Suspension oil cylinder

Technical field

The utility model relates to machinery manufacturing technology field, especially a kind of suspension oil cylinder for building engineering construction or mining.

Background technique

Common oil hydraulic cylinder is all generally single cylinder active force, has occurred in recent years a kind of oil cylinder rod of processing multiple horizontal oil cylinders on a workpiece, and structure as depicted in figs. 1 and 2; Oil cylinder rod is inserted in the hole of having bored at rock, concrete etc. in advance, with ultrahigh-pressure hydraulic station, drive again, in order to division, abolish rock, concrete etc., in some occasions, can substitute explosive, dilatant, should be in mining, engineering construction, dismounting operation, rescue and relief work etc.; But there is the shortcoming of following four aspects in this oil cylinder rod: 1) oil cylinder rod is long, is relatively difficult to put into hole, very high to drilling quality requirement, limited greatly application; 2) due to processing difficulties, cannot be worked into the length of most of use occasion demands, be difficult to meet the needs of longer darker operating environment, in a lot of operating mode occasions, all cannot meet the demands and can not get application; 3) all pistons are all towards identical, the oil cylinder body dorsad one side of piston bears powerful pressure, but in real work, impossible straight again with the oil cylinder body working surface that the one side of piston contacts dorsad, cause oil cylinder body distortion distortion, be easy to lose efficacy and damage; 4) due to oil cylinder dorsad the one side of piston to bear powerful pressure, so oil cylinder rod must do to obtain the requirement competent at a job of thick ability, but it is the smaller the better in most of applications, to wish again that hole drill obtains; Not only cost is high for thick oil cylinder rod, and applicable surface is all the better little.

Because there are above several large shortcomings, former oil cylinder rod technology, always only in the experimental stage, cannot be applied.

Model utility content

The purpose of this utility model is to provide a kind of suspension oil cylinder, it can solve the yielding distortion of prior art oil cylinder body this suspension oil cylinder, the problem that easily lost efficacy and damage and have the requirement that is not suitable with building engineering construction or the longer darker operating environment of mining; Solve dilatant and the shortcoming of explosive in mining and building engineering construction, have safety, efficiently, environmental protection, low energy consumption, low cost, widely applicable feature.

In order to address the above problem, the technical solution adopted in the utility model is:

This suspension oil cylinder, comprises the cylinder body that is provided with multiple oil hydraulic cylinders, and described cylinder body has multiple, and the oil inlet pipe of these cylinder bodies is interconnected, and is provided with two pistons that moving direction is contrary in multiple oil hydraulic cylinders of described cylinder body.

In above technological scheme, further scheme is: described cylinder body one end is provided with connection boss, and the other end is provided with for being connected with another cylinder body described the groove that boss connects, and described connection boss and groove are provided with connecting hole; After inserting in the groove of another cylinder body by the connection boss of a cylinder body between two described cylinder bodies, with joint bolt, be fixedly connected with.

Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, the utility model is connected into a long oil cylinder rod by the shorter oil cylinder rod of more piece, it is boss that every joint rod is designed to one, one is groove, can use separately, also can be combined into according to actual needs the length that meets operating mode needs, the connection of multiple-joint oil tank rod simultaneously makes whole piece oil cylinder rod have certain swing rubbing, can easily insert in deep hole, not only improve greatly application, simultaneously not high to the quality requirement of boring yet;

2, the utility model piston by unidirectional towards change into two-way towards, oil cylinder body is suspended completely, reach long-lived order ground; Because cylinder body suspends completely, pressure all acts on piston, just can be designed to tiny oil cylinder rod simultaneously, and application is more extensive, more can greatly reduce costs.

3, the utility model and explosive and dilatant contrast, outstanding advantage is: safety, efficient, environmental protection, low energy consumption, low cost, widely applicable.

4, the utility model is having great advantage aspect alternative dilatant, at present the application such as exploitation granite, marble, jade, sandstone, green stone maximum be dilatant, dilatant is industrial chemicals after all, no matter be produce or use, all environment is had to pollution, operate also more dangerous simultaneously, main is that dilatant is article of consumption, disposable use, and user cost is high, and this technical products is reusable equipment, user cost is far below the former; Dilatant is owing to being chemical slow reaction, operation cycle is long, generally taking 1-3 days just can complete a duty cycle, and this technology only needs a few minutes just can complete a duty cycle, efficiency improves hundred times far more than, this technology can be under water, high temperature, low temperature and having in the environment of explosion risk is used, the far super dilatant of application area and explosive.
