Description

An anti-shock full-section adjustable self-balancing mine support device

technical field

The invention relates to the technical field of coal mine underground or tunnel support, in particular to an anti-shock full-section adjustable self-balancing mine support device.

Background technique

At present, metal support technology has been widely used in tunnel support of mine roadways, railways and various underground projects at home and abroad. With the maturation of roadway metal support technology, the application in mine roadway or tunnel support is becoming more and more important. There are many types of traditional support devices. Through the application of different types of support devices in engineering, it is found that the existing support devices have poor overall structural stability and uneven force during the support process. Due to the deviatoric stress of the surrounding rock, it is easy to cause damage under the extrusion of the surrounding rock deformation, and it is difficult to apply a relatively uniform supporting force to the rock mass around the entire section of the roadway. Excessive force on the local structure will easily lead to the reduction of the overall structural support strength and the main disadvantages such as ineffective support.

For example, the utility model patent (CN201982126U) discloses a portal roadway support bracket, which can support the roadway that encounters a special geological structure zone or mine pressure concentrated appearance. For example, the utility model patent (CN201826852U) discloses a coal-rock roadway Shock abdication and energy-absorbing support device can improve the impact resistance of the support device. For example, the invention patent (CN102182478A) discloses a mine-used rapid wave dissipation and energy consumption buffer device, which reduces the damage of impact load to equipment and staff .

In summary, the traditional support device has the following disadvantages:

1. It is difficult to apply a relatively uniform support force to the surrounding rock during the support process, and its own structural adjustment ability is poor. The deformation of the roadway surrounding rock has a greater impact on the support structure, and the support structure is easily deformed due to excessive local load. The overall support structure is unstable and damaged or fails;

2. In the prior art, metal bracket support is a passive support method, and it is difficult to obtain ideal support effects, especially for impact mine roadways. During the roadway support process, under the influence of strong mine pressure, it is affected by impact dynamic Due to the impact of load, it often occurs that the support device cannot adapt to the severe deformation of the surrounding rock well, and is easily subjected to local deformation and extrusion loads of the surrounding rock, resulting in excessive local stress on the structure, which leads to the overall stability of the support being easily reduced, and deformation and failure occur. Can not give full play to its supporting performance;

On-site construction must adapt the support structure to the deformation of the surrounding rock, strengthen the coupling relationship between the support structure and the surrounding rock, and give full play to the overall supporting force of the support structure while limiting the deformation of the surrounding rock, otherwise it is not conducive to the bearing structure of the surrounding rock The formation and adjustment of the surrounding rock will easily lead to the reduction of the self-supporting capacity of the surrounding rock, resulting in excessive convergence deformation of the roadway.

The outer side member Ⅰ3 includes: two left and right symmetrical curved curved plates Ⅰ3-1, the upper end of the curved curved plate Ⅰ3-1 is attached to the upper side of the end of the arch part Ⅰ2, and the outer side member Ⅱ4 includes: left and right Two symmetrical arc-shaped curved plates II4-1, the lower end of the arc-shaped curved plate II4-1 is attached to the lower side of the end of the arch II5, and the lower end of the arc-shaped curved plate I3-1 is connected to the arc-shaped curved plate II4-1 The upper end of the upper end is superimposed on the left and right, and the outer side of the lower end of the curved curved plate I3-1 and the upper end of the curved curved plate II4-1 are also sleeved with a clamp 1;

In this embodiment, the clamp 1 provided not only ensures that the overall support device has a certain initial support force, but also ensures that the support device has the ability to be retractable when the surrounding rock is deformed and squeezed too much during the support process. , the hydraulic shock-isolation and force-transmitting elastic member 6 cooperates with the retractability of the support device, and adjusts and controls the overall retractability through the tightness of the clamp 1. A schematic example is used to illustrate: use the nut on the clamp 1 to twist Adjust the initial supporting force of the support device to the surrounding rock by adjusting the tightening torque, and cooperate with the hydraulic shock-isolation and force-transmitting elastic member 6 to jointly bear the load and homogenize the force, so as to ensure that all parts interact and carry the load together during the support of the surrounding rock, and improve the load-bearing capacity of the supporting device;

Specifically, one side of the curved section I2-1 is fixedly connected to the rib plate I2-2, and the rib plate I2-2 is flexibly connected to the rib plate II3-2 through the hydraulic shock-isolation force-transmitting elastic member 6, and the rib plate II3-2 is fixedly connected to On one side of the arc-shaped curved plate Ⅰ3-1, the side of the curved section Ⅱ5-1 is fixedly connected with the rib plate Ⅲ5-3, and the rib plate Ⅲ5-3 moves with the rib plate Ⅳ4-3 through the hydraulic shock-isolation force-transmitting elastic member 6 connection, the rib plate IV4-3 is fixedly connected to one side of the curved curved plate II4-1, the side of the curved curved plate I3-1 is also fixedly connected to the rib plate V3-4, and one side of the curved curved plate II4-1 The ribs Ⅵ4-5 are fixedly connected to the side, and the ribs Ⅵ3-4 and the ribs Ⅵ4-5 are flexibly connected through the hydraulic shock-isolation and force-transmitting elastic member 6;

The hydraulic vibration isolation force transmission elastic member 6 buffers and transmits the active force. In this embodiment, the hydraulic vibration isolation force transmission elastic component 6 includes: a hydraulic shock absorber and an elastic element, as shown in Figures 3 and 4, the hydraulic vibration isolation The shock absorber is a well-known technology in the art. The elastic element is preferably a compression spring with high strength and high elasticity, and the elastic element is sleeved on the outside of the hydraulic shock absorber. Schematic illustration: In Fig. 3, the elastic element One set of moment arms fits with rib plate III5-3; the other set of moment arms fits with rib plate IV4-3;

The effect of force is mutual. The setting of the hydraulic shock-isolation force-transmission elastic member 6 realizes two-way support and force transmission, which can withstand deformation, buffer the deformation load of the external surrounding rock, and can also withstand the impact of dynamic load;

Specifically, when the arched part I2 and the arched part II5 bear the force in the vertical direction, the arched part I2 and the arched part II5 move toward each other, and the two ends of the arched part I2 and the arched part II5 are both facing the air. The force is exerted by the hydraulic shock-isolation force-transmitting elastic member 6 in the cavity, so that the hydraulic shock-isolation transmission between ribs I2-2 and rib II3-2, and between ribs III5-3 and rib IV4-3 The force elastic member 6 shrinks;

When the outer side member I3 and the outer side member II4 bear the force in the vertical direction, the outer side member I3 and the outer side member II4 move toward each other, and the two ends of the outer side member I3 and the outer side member II4 Apply the force to the hydraulic shock-isolation force-transmitting elastic member 6 in the cavity, so that the hydraulic shock-isolation force-transmitting elastic member 6 between the rib plate V3-4 and the rib plate VI4-5 shrinks;

When the outer skirt member I3 and the outer skirt member II4 bear the force in the horizontal direction, the outer skirt member I3 and the outer skirt member II4 both move toward the cavity, and the middle parts of the outer skirt member I3 and the outer skirt member II4 both move toward the cavity. Applying this force to the hydraulic shock-isolating force-transmitting elastic member 6 in the cavity also makes the hydraulic isolation between the ribs I2-2 and II3-2, and between the ribs III5-3 and Shock transmission force elastic member 6 shrinks;

Of course, ribs I2-2, ribs II3-2, ribs III5-3, ribs IV4-3, ribs V3-4, and ribs VI4-5 are all pre-processed with concave notches and mounting holes I2- 3. Installing round hole Ⅱ3-3, installing round hole Ⅲ3-5, installing round hole Ⅳ4-2, installing round hole Ⅴ4-4, installing round hole Ⅵ5-4, hydraulic vibration isolation force transmission elastic member 6 and each rib The installation and connection are all fastened by the installation pin 7, which is convenient for disassembly and assembly, and is conducive to the installation and recycling of the support device;

In the above-mentioned embodiment, since the support device is a whole, each structure interacts with each other to improve the stress state of the support, and apply a relatively uniform support resistance to the surrounding rock, and the force generated in any direction (such as surrounding The load generated by rock deformation and extrusion) can be transferred between each structure, and the external surrounding rock deformation load borne by the support device can be alleviated and evened by its own structure, and its stress state can be improved and optimized, which is easy The force of the support device tends to be balanced, and its bearing capacity is enhanced, which is conducive to the joint force of each component, coordinates with the deformation of the surrounding rock, adapts to the deformation of the surrounding rock, and stabilizes the surrounding rock;

Schematic illustration: In the above-mentioned embodiment, when the outer side member I3 and the outer side member II4 bear the force in the vertical direction, the hydraulic shock-isolation force transmission elasticity between the rib plate V3-4 and the rib plate VI4-5 Component 6 shrinks, and because the force is mutual, the hydraulic shock-isolation force-transmitting elastic component 6 also applies the force to the outer side member I3 and outer side member II4 in reverse, and the forces cancel each other out. The shrinkage and deformation between the side member Ⅰ3 and the outer side member Ⅱ4 can effectively avoid the overall damage and failure of the support device due to excessive impact dynamic load. 6 On the one hand, it can be deformed to adapt to the deformation of surrounding rocks and transmit loads; on the other hand, it can also withstand large loads, and has a certain supporting capacity to ensure the strength of the supporting structure;

The hydraulic shock-isolation and force-transmitting elastic member 6 can also transmit the force, which is beneficial to the overall uniform force, and also reduces the damage to the supporting device caused by the deformation of the surrounding rock under the influence of strong mine pressure. A schematic example: when the arch Ⅰ2 When bearing the force in the vertical direction, its two ends apply the force to the hydraulic shock-isolation force-transmitting elastic member 6 in the cavity. Since the support device is a whole, the load generated by the force passes through the support device. It is transmitted to the side and bottom of the roadway, so that the force in the vertical direction (the deformation and extrusion load of the top surrounding rock) is used to limit the convergence deformation of the side of the roadway and the surrounding rock at the bottom, reduce the loss of support resistance, and ensure that the surrounding rock in the support During the process, each component interacts and bears together, which improves the bearing capacity of the support device and is conducive to stabilizing the surrounding rock;

When the outer side member I3 bears the force in the horizontal direction, the upper end of the outer side member I3 can move along the upper end surface of the arch I2. Similarly, when the outer side member II4 bears the force in the horizontal direction, the outer The lower end of the side member II4 can move along the lower end surface of the arch II5, and can move with each other to form contraction when subjected to force. In a word, the upper and lower positions can move and transmit loads to support the top and bottom of the roadway;

Of course, in addition to the force in the X-axis and Y-axis of the support structure in this embodiment, the surrounding rock in any direction can apply force to the support structure. The X-axis and Y-axis of the supporting structure are stressed, but the supporting structure is not limited to the usage scenarios of the X-axis and Y-axis;

In summary, regardless of the force in any direction, the hydraulic shock-isolation force-transmitting elastic member 6 cooperates with the shrinkability of the support structure to ensure the support of all sections, and the hydraulic shock-isolation force-transmitting elastic member 6 counteracts the appearance of strong mine pressure The deformation load of the surrounding rock can shrink and deform at the same time to effectively avoid the overall damage and failure of the support device due to excessive impact dynamic load, and enhance the coordination ability of the structure of each part of the support device and the deformation of the surrounding rock, improving its Support performance;

It should be noted that the force in this embodiment includes at least impact dynamic load and deformation extrusion load, and of course the force may also include earthquake force, blasting force, etc.;

Considering the problem of load transfer, the edges of outer side member I3 and outer side member II4 can be widened to facilitate load transfer while ensuring shrinkability;

Considering the shrinkage problem, the initial state of the middle part of the arch part II5 is disconnected, as shown in Figure 2, the middle part of the arch part II5 can be superimposed on each other and connected together by the clamp 1, as shown in Figure 1, So that when the supporting device is contracted, the left and right sides of the arch II5 can move toward each other to facilitate the contraction of the supporting device.
