Description
Technical Field
The utility model belongs to the technical field of colliery hydraulic support, concretely relates to two post support formula dysmorphism back timber hydraulic support.
Background
At present, special supports such as a crossheading forepoling, a supporting hydraulic support and the like are generally adopted for temporary support of a coal mine dynamic pressure roadway, and although the effect of reinforcing support is achieved, the following problems exist: the special support for temporary support at present is a flat top beam structure, and although the support area is large, the outer anchor heads of all anchor rods (cables) in the support range of the flat top beam cannot be avoided, the outer anchor heads are extruded to easily cause the support failure of the anchor rods (cables), the support strength is reduced, and dynamic pressure roadway deformation is aggravated.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a two post support formula dysmorphism back timber hydraulic support, when solving current dynamic pressure tunnel temporary support and strut with special type support, there is the problem that can crowd bad stock (cable).
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a two post supporting type dysmorphism back timber hydraulic support, includes the base, be provided with the stand of two liftable on the base, the top of stand is provided with flat back timber, the top of flat back timber is provided with a plurality of supporting beam.
As an optimized technical scheme of the utility model, be provided with two pneumatic cylinders, two on the base the stand is provided with respectively on the drive end of two pneumatic cylinders.
As a preferred technical solution of the present invention, the supporting beams are two in number and arranged in parallel.
As an optimized technical scheme of the utility model, a supporting beam passes through the bolt fastening on the flat top beam.
As a preferred technical solution of the present invention, two of the supporting beams are transversely or longitudinally arranged on the flat top beam.
The utility model has the advantages that: to the problem that present temporary support exists with flat back timber special type support, the utility model provides a two post support formula dysmorphism back timber hydraulic support, this kind of support not only can temporary support dynamic pressure tunnel, and its superiority is present moreover: the outer anchor head of the anchor rod (cable) can be protected when the top plate is supported, the anchor rod (cable) is ensured to be effectively supported, and the temporary strengthening supporting effect of the dynamic pressure roadway is improved.

Detailed Description
As shown in fig. 1, the utility model discloses a two-column support formula dysmorphism back timber hydraulic support, including base 1 for support whole device.
Referring to fig. 2, two lifting columns 2 are arranged on the base 1, and a flat top beam 3 is arranged at the top of each column 2. The upright posts are used for supporting the flat top beam 3, and the height of the upright posts can be adjusted to adjust the position of the flat top beam 3.
Referring to fig. 3, a plurality of support beams 4 are provided on the top of the flat top beam 3.
Referring to FIG. 4, the height of the support beam 4 is 30mm to 500mm. The working state of the two-column supporting type special-shaped top beam hydraulic support is shown in figure 4, the support is supported in a dynamic pressure roadway, the outer anchor head of the anchor rod (cable) is positioned in a non-supporting space between a plurality of supporting beams 4 or a non-supporting space between two adjacent unit supports, the height of the supporting beam is not lower than that of the outer anchor head of the anchor rod (cable), and the outer anchor head of the anchor rod (cable) of the top plate is not damaged when the two-column supporting type special-shaped top beam hydraulic support supports the top plate.
During the dynamic pressure display period of a dynamic pressure roadway, a two-column supporting type special-shaped top beam hydraulic support is adopted to support a top plate, a supporting beam 4 of the support is arranged between two adjacent rows of anchor rods (cables), then the upright columns 2 are lifted, the supporting beam 4 is ensured to act on the top plate, and the initial supporting force of the upright columns 2 reaches the design requirement. After the roadway is pressed, the upright posts 2 are lowered, and then the two-post supporting type special-shaped top beam hydraulic support is moved to other positions.
Combine fig. 2 in the utility model discloses an among two post supporting type dysmorphism back timber hydraulic support, be provided with two pneumatic cylinders 5 on the base 1, two stands 2 set up respectively on the drive end of two pneumatic cylinders 5, can adjust stand 2 height through drive pneumatic cylinder 5, and then realize supporting beam 4's altitude mixture control.
In addition, the upright post 2 can also be directly supported by a jack.
Referring to fig. 4, in the two-column supporting type hydraulic prop of the present invention, the supporting beams 4 are two in number and arranged in parallel.
The utility model discloses a when two post support formula dysmorphism back timber hydraulic support strutted, stock (cable) were located two supporting beam 4 between, can accomplish the strutting to the roof on the one hand, and on the other hand can not the pressure loss stock (cable).
With reference to fig. 2, the utility model discloses an among two post supporting type dysmorphism back timber hydraulic support, a supporting beam 4 passes through bolt 6 to be fixed on flat back timber 4, and it is comparatively convenient to assemble.
Combine figure 4 in the utility model discloses an among two post support formula dysmorphism back timber hydraulic support, two support beam 4 are horizontal or longitudinal arrangement on flat back timber 3, can adjust according to the in bank arrangement mode of stock (cable) and select to adapt to different operating mode requirements.
Therefore, compared with the prior art, the utility model discloses a two post support formula dysmorphism back timber hydraulic support to the problem that exists with flat back timber special type support at present temporary support, the utility model provides a two post support formula dysmorphism back timber hydraulic support, this kind of support not only can temporary support the dynamic pressure tunnel, and its superior appearance is present moreover: the outer anchor head of the anchor rod (cable) can be protected when the top plate is supported, the support effect of the anchor rod (cable) is ensured, and the temporary strengthening support effect of the dynamic pressure roadway is improved.
