Abstract
The invention belongs to mining equipment technology fields, provide a kind of lift bottom method of hydraulic support, it include: to be connected to one end of two lifting equipments on the top beam of bracing hydraulic support of the hydraulic support the right and left for being located at the bottom to be lifted, the other end is then connect with the pedestal of the hydraulic support at the bottom to be lifted；Fall the top beam of the hydraulic support at the bottom to be lifted；Start the lifting equipment, completes to lift work to the pedestal of the hydraulic support at the bottom to be lifted.It is lift bottom provided by the invention method safety, reliable.
Description
Technical field
The present invention relates to mining equipment technology fields, and in particular to a kind of lift bottom method of hydraulic support.
Background technique
Currently, hydraulic support is the main support apparatus of underground coal mine fully-mechanized mining working.Due to most underground coal mine geology
Complicated condition, bottom plate are mostly the mud stone or argillaceous sandstone of soft easy argillization, and leading to hydraulic support, pedestal is easily pricked in use
Bottom, i.e. hydraulic support foundation fall into seat earth, cause during coal mining, and hydraulic support needs are tried to stop people from fighting each other when moving forward, it is desirable to
Pedestal must be lifted before moving frame, can guarantee smoothly to move frame.At present still without preferably lifting bottom method, so that needing
When moving frame, phenomena such as leading to passage oil cylinder, connector damage in trying to stop people from fighting each other by force is frequently appeared in.
Summary of the invention
For the defects in the prior art, the object of the present invention is to provide a kind of lift bottom methods of hydraulic support, so that lift
Bottom is safer, more reliable, with reduce tradition lift bottom during because try to stop people from fighting each other by force to passage oil cylinder, connector etc. damage can
It can property.
To achieve the goals above, the present invention provides a kind of lift bottom method of hydraulic support, the hydraulic support at bottom to be lifted
There are a bracing hydraulic support in two sides, the lift bottom method of the hydraulic support the following steps are included:
One end of two lifting equipments is connected to the bracing hydraulic support the right and left for being located at the bottom to be lifted
On the top beam of hydraulic support, the other end is then connect with the pedestal of the hydraulic support at the bottom to be lifted；
Fall the top beam of the hydraulic support at the bottom to be lifted；
Start the lifting equipment, completes to lift work to the pedestal of the hydraulic support at the bottom to be lifted.
Further, the lifting equipment is jack.
Further, the lifting equipment is also possible to hoist crane.
Beneficial effects of the present invention: a kind of lift bottom method of hydraulic support provided by the invention makes full use of hydraulic jack
The power on top realizes lifting for the pedestal of hydraulic support, safe and reliable, and also significantly reduces tradition lift bottom in the process because strong
Capable a possibility that being damaged to passage oil cylinder, connector etc. of trying to stop people from fighting each other.
Detailed description of the invention
It, below will be to specific in order to illustrate more clearly of the specific embodiment of the invention or technical solution in the prior art

As shown in Figure 1, a kind of lift bottom method of hydraulic support provided in this embodiment, on a left side for bottom hydraulic support 1 to be lifted
There is a bracing hydraulic support 2 on right both sides, the lift bottom method of the hydraulic support the following steps are included:
One end of two lifting equipments 3 is connected to the branch for being located at 1 the right and left of hydraulic support at the bottom to be lifted
On the top beam 4 for supportting hydraulic support, it is preferable that be connected on the connection pin shaft 6 of top beam 4, in order to connect.The other end then with it is described
The pedestal 5 of the hydraulic support 1 at bottom to be lifted connects, it is preferable that the other end is connected to the base bridge 8 of pedestal 5 by round-link chain 7
On, so lift bottom is also convenient for convenient for connection；
The top beam 4 for falling the hydraulic support 1 at the bottom to be lifted, so that the pedestal 5 of the hydraulic support 1 at the bottom to be lifted will not
The pressure transmitted from top beam 4 due to pedestal 5 lifts is born, in order to the lift of the pedestal 5 of the hydraulic support 1 at the bottom to be lifted
It rises；
Start the lifting equipment 3, completes to lift work to the pedestal 5 of the hydraulic support 1 at the bottom to be lifted.
Preferably, the lifting equipment 3 is jack, is also possible to the scalable lifting of hoist crane or other forms
Equipment.
