Abstract
The utility model discloses a clamping cable for a rock burst preventing support, and particularly belongs to the field of underground coal mine roadway supporting devices. The clamping cable comprises an upper clamping plate, a lower clamping plate and a bolt. Grooves with corresponding notches are formed in middles of the upper clamping plate and the lower clamping plate, and the corresponding edges of the upper clamping plate and the lower clamping plate are firmly connected through the bolt. The clamping cable can be tightly attached to the rock burst preventing support, so that strength is effectively improved, and the stress capability of the clamping cable is improved.
Description
[technical field]
The utility model relates to coal mine down-hole tunnel support apparatus field, especially relates to a kind of card cable that is applied to protecting against shock and presses support.
[background technology]
Known, card cable is to be applied in protecting against shock to press the connection keeper in support, when application, in order to improve the slip resistance of support, often requires card cable to have the force intensity of being subject to large, safety and stability and robust characteristic; Yet, because most card cable is all directly to be bent and form by steel plate, it has the problems such as intensity is low, mutability in application, the U-shaped steel of two joints being connected by card cable is in application process during relative sliding, its frictional force is less, easily make the U-shaped steel of two joints produce relative slippage, this not only has influence on the safety and stability of support, and the pressure bearing when support is when larger, card cable is also prone to distortion, thereby directly have influence on protecting against shock, press the supporting capacity of support, and then directly have influence on construction safety.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of protecting against shock and press card cable for support, described card cable can with protecting against shock press support to fit tightly, thereby effectively increased intensity, improved the stress-bearing capability of card cable.
For achieving the above object, the utility model adopts following technical scheme:
A card cable for support is pressed on protecting against shock ground, and described card cable wrap is containing upper clamp, lower clamp and bolt; Described upper clamp and the middle part of lower clamp are provided with the groove that notch is corresponding, and upper clamp and edge corresponding to lower clamp are by the firm connection of bolt.
Card cable for support is pressed on described protecting against shock ground, and the groove of described upper clamp is made as flat U-lag, and the groove of described lower clamp is made as dovetail groove.
Card cable for support is pressed on described protecting against shock ground, and the groove of described lower clamp is made as corresponding protecting against shock presses the dovetail groove of contoured cradle.
Card cable for support is pressed on described protecting against shock ground, and described upper clamp is that Q345A steel is made.
Card cable for support is pressed on described protecting against shock ground, and described lower clamp is that ZG310-570 steel is made.
Card cable for support is pressed on described protecting against shock ground, and described bolt and corresponding supporting nut are made by Q345A steel.
Owing to adopting technical scheme as above, the utlity model has following beneficial effect:
Protecting against shock described in the utility model ground presses support not only simple in structure with card cable, be easy to install, and after installation with protecting against shock press support laminating closely, sturdy and durable, effectively reached increase intensity, promote stress-bearing capability, prevent the object of distortion.
[accompanying drawing explanation]
Fig. 1 is schematic diagram of the present utility model.
In figure: 1, upper clamp; 2, lower clamp; 3, bolt; 4, nut.
[specific embodiment]
By the following examples, can explain in more detail the present invention, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
Card cable for support is pressed on protecting against shock described in 1 ground by reference to the accompanying drawings, and described card cable wrap is containing upper clamp 1, the lower clamp 2 of being made by ZG310-570 steel and the bolt 3 made by Q345A steel, described upper clamp 1 and the middle part of lower clamp 2 are provided with the groove that notch is corresponding, the groove of upper clamp 1 is made as flat U-lag, the groove of lower clamp 2 be made as with protecting against shock press the contoured cradle corresponding dovetail groove that coincide, and upper clamp 1 is connected by bolt 3 at the edge of correspondence mutually with lower clamp 2, thereby by with protecting against shock press the lower clamp 2 of the corresponding laminating of contoured cradle to reach enhancing support intensity, improve the object of card cable stress-bearing capability, simultaneously, this has also guaranteed that bolt 3 only can bear longitudinal pulling force when support force, and do not bear horizontal shearing force, strengthened the resistance to tension of bolt 3, played the effect that prevents the distortion of card cable, for strengthening bonding strength, can adopt by Q345A steel and make bolt 3 and supporting nut 4 corresponding to bolt 3.
Implement protecting against shock described in the utility model and press support to use while blocking cable, first by protecting against shock press in support corresponding link correspondence together, then described card cable correspondence is pressed together on to the junction of support, then by bolt 3 and nut 4, upper clamp 1 and lower clamp 2 is tightened together and completed attended operation.
The utility model does not describe part in detail for prior art, therefore the utility model is not described in detail.
