In the actual operation process, over-winding and over-release accidents, inclined tunnel mine car decoupling, stall and other accidents will inevitably occur. Many steel belt energy absorption equipment on the market do not have the ability to load gradually, which leads to poor braking effect, so it needs to be improved. Summary of the invention

The present application provides a steel belt type energy absorption buffer brake device in inclined lane transportation, which adopts the following technical scheme: the steel belt type energy absorption buffer brake device in inclined lane transportation comprises a shell, a coiled steel belt, an inclined plane driving member, a dynamic pressure unit, a fixed pressure unit, a traction member and a connecting member; the coiled steel belt is installed inside the shell, the inclined plane driving member is horizontally slidably installed in the shell, and the inclined plane driving member is located below the coiled steel belt, the dynamic pressure unit is vertically slidably installed inside the shell, and the fixed pressure unit is fixedly installed inside the shell; part of the coiled steel belt passes through the gap between the dynamic pressure unit and the fixed pressure unit, the movable end of the coiled steel belt is connected to the traction member, the inclined plane driving member is connected to the traction member through the connecting member, and an inclined surface is arranged on the inclined plane driving member, and when the traction member moves away from the shell, the inclined surface gradually lifts the dynamic pressure unit, and the dynamic pressure unit cooperates with the fixed pressure unit to squeeze part of the coiled steel belt to a bent state. By adopting the above technical solution, when the traction member is moved by force, the coiled steel belt connected thereto and the inclined plane driving member move together. When the inclined plane driving member moves, the inclined plane pushes the dynamic pressure unit to move upward to cooperate with the fixed pressure unit to squeeze part of the coiled steel belt, so that the coiled steel belt is bent and deformed. The deformation process of the coiled steel belt is the process of generating braking force. The braking force increases from small to large and then reaches the maximum value, realizing the gradual loading of the braking force. The coiled steel belt is installed in the shell after coiling and forming, so as to achieve the effect of saving space. Due to the coiling and forming of the coiled steel belt, the steel belt can be set to be very long, so that the braking force is continuously output. Optionally, the dynamic pressure unit is a dynamic pressure roller, and the two ends of the dynamic pressure roller are rotatably installed on the inner wall of the shell. The shell is provided with a vertical slide groove adapted to the end of the dynamic pressure roller. The dynamic pressure roller is arranged horizontally and perpendicular to the movement direction of the inclined plane driving member. By adopting the above technical solution, the vertical slide groove provides a stable lifting track for the dynamic pressure roller, and also plays a role of limiting and blocking the dynamic pressure roller, and the structural design is simple, which is easy to install and disassemble; the dynamic pressure roller is generally a cylindrical structure, and the contact area between the dynamic pressure roller and the lower surface of the coiled steel belt is relatively small. In the process of the coiled steel belt moving and absorbing energy, the friction loss between the dynamic pressure roller and the coiled steel belt is relatively small, which significantly extends the service life of the coiled steel belt. Optionally, the fixed pressure unit is two fixed pressure rollers, both ends of which are installed on the inner wall of the shell, and the fixed pressure rollers are provided with two and are arranged at intervals on the same horizontal plane, and the dynamic pressure roller is located between the two fixed pressure rollers, and the fixed pressure roller is parallel to the dynamic pressure roller.By adopting the above technical scheme, two fixed pressure rollers cooperate with a dynamic pressure roller to better squeeze the local coiled steel belt and deform it into a bent state, making the braking smoother; the fixed pressure roller is generally a cylindrical structure, and the contact area between the fixed pressure roller and the upper surface of the coiled steel belt is relatively small. In the process of the coiled steel belt absorbing energy during movement, the friction loss between the fixed pressure roller and the coiled steel belt is relatively small, which significantly extends the service life of the coiled steel belt. Optionally, the inclined plane driving member includes a sliding block, a traction rod and a core rod, the inclined plane is arranged on the sliding block, a traction groove is arranged in the sliding block, the traction rod includes a rod portion and a protrusion, one end of the rod portion is connected to the connecting member, and the protrusion is arranged at the end of the rod portion away from the connecting member; the inner side wall of the traction groove is provided with a pit, and the surface of the pit and the protrusion are provided with mutually fitting oblique surfaces, the width of the traction groove is equal to the sum of the diameter of the core rod and the diameter of the rod portion, and the end of the core rod away from the traction rod is fixedly installed on the shell; when the dynamic pressure unit moves to the highest position, the traction rod can be separated from the traction groove. By adopting the above technical solution, when the traction rod moves with the traction member, the sliding block moves with the traction rod in the early stage because the protrusion engages with the inclined surface of the pit and the core rod abuts the traction rod; when the dynamic pressure unit moves to the highest position, the traction rod slides to a position where it cannot contact the core rod, and then the traction rod can be separated from the traction groove, and the traction member automatically unhooks after braking, and the structure is simple and practical. Optionally, two spaced and horizontally arranged slide rails are provided on the inner bottom wall of the shell, and the slide rails are parallel to the movement direction of the traction member, and a slide groove matching the slide rails is provided at the bottom of the sliding block. By adopting the above technical solution, the slide rails and the slide grooves slide and cooperate, which improves the stability of the sliding block when it slides inside the shell, which is conducive to the inclined surface of the sliding block driving the dynamic pressure unit to rise stably, and the above structural design is simple, which is convenient for installation and later maintenance. Optionally, the top surface of the sliding block is set as a plane, and the plane is used to support the bottom of the dynamic pressure unit. By adopting the above technical solution, when the dynamic pressure unit is driven to the highest position by the inclined plane, the bottom of the dynamic pressure unit contacts the above plane. Due to the bending and the coiled steel belt in the energy absorption process, a large downward pressure is exerted on the dynamic pressure unit. If there is no above plane, this downward pressure will generate a horizontal force driving the sliding block to move in the opposite direction under the action of the inclined plane. Therefore, the above plane can effectively prevent the sliding block from resetting in the opposite direction, and the whole structure is more stable and firm, and has higher safety. Optionally, an arc-shaped groove is provided on the plane, and the maximum depth of the arc-shaped groove is 2 cm. By adopting the above technical solution, the arc-shaped groove can make the dynamic pressure unit more stable on the plane, thereby keeping the coiled steel belt in a bent state, and achieving better braking effect. Optionally, it also includes a limiting roller fixedly installed inside the shell, and the connection between the traction member and the coiled steel belt is on the same horizontal plane as the bottom of the limiting roller.By adopting the above technical solution, the limiting roller can keep the section of the coiled steel belt adjacent to the traction member in a horizontal state, which is conducive to the traction member to stably drive the coiled steel belt to move, and the safety is higher. Optionally, the traction member is a U-shaped shackle, and the U-shaped shackle is provided with a clamping plate for clamping the movable end of the coiled steel belt, and the clamping plate is attached to the lower surface of the coiled steel belt. By adopting the above technical solution, the U-shaped shackle is a common accessory, easy to purchase, low cost, small in size and large in load-bearing weight, and the contact area between the clamping plate and the movable end of the coiled steel belt is relatively large, so that the connection between the movable end of the coiled steel belt and the U-shaped shackle is more secure. Optionally, the connecting member is a wire rope or a lifting belt. By adopting the above technical solution, the wire rope or the lifting belt has high tensile strength, fatigue resistance and impact toughness, good softness, suitable for traction and pulling, and is a common accessory, easy to purchase, and low in cost. In summary, the present application includes at least one of the following beneficial technical effects: 1. When the traction member is moved by force, the coiled steel belt and the inclined driving member connected thereto move together. When the inclined driving member moves, the inclined surface pushes the dynamic pressure unit to move upward to cooperate with the fixed pressure unit to squeeze part of the coiled steel belt, so that the coiled steel belt is bent and deformed. The deformation process of the coiled steel belt is the process of generating braking force. The braking force changes from small to large and then reaches the maximum value, realizing the gradual loading of the braking force. The coiled steel belt is installed in the shell after coiling and forming, achieving the effect of saving space. The coiled steel belt can be set to be very long due to the coiling and forming, so that the braking force is continuously output. 2. When the traction rod moves with the traction member, in the early stage, because the protrusion is engaged with the pit inclined surface and the core rod abuts the traction rod, the sliding block moves with the traction rod; when the dynamic pressure unit moves to the highest position, the traction rod slides to a position where it cannot contact the core rod, and then the traction rod can be separated from the traction groove, and the traction member automatically unhooks after braking, with a simple and practical structure.

DETAILED DESCRIPTION

[0005] The following is combined with Figure 1-5 The present application is further described in detail. The present application embodiment discloses a steel belt type energy absorbing buffer brake device in inclined lane transportation. Figure 1 and Figure 2 The steel belt type energy absorption buffer brake device in the inclined lane transportation includes a shell 1, a coiled steel belt 2, an inclined plane driving member 3, a dynamic pressure unit 4, a constant pressure unit 5, a traction member 6 and a connecting member 7. The coiled steel belt 2 is installed inside the shell 1, the inclined plane driving member 3 is horizontally slidably installed inside the shell 1, and the inclined plane driving member 3 is located below the coiled steel belt 2, the dynamic pressure unit 4 is vertically slidably installed inside the shell 1, and the constant pressure unit 5 is fixedly installed inside the shell 1; part of the coiled steel belt 2 passes through the gap between the dynamic pressure unit 4 and the constant pressure unit 5, the movable end of the coiled steel belt 2 is connected to the traction member 6, the inclined plane driving member 3 is connected to the traction member 6 through the connecting member 7, and an inclined surface 311 is provided on the inclined plane driving member 3, and the inclination angle and length of the inclined surface 311 are adjusted according to actual needs. When the traction member 6 moves away from the shell 1, the inclined surface 311 gradually lifts the dynamic pressure unit 4, and the dynamic pressure unit 4 cooperates with the constant pressure unit 5 to squeeze part of the coiled steel belt 2 to a bent state. The dynamic pressure unit 4 is a dynamic pressure roller, which is made of 45# steel. Both ends of the dynamic pressure roller are rotatably mounted on the inner wall of the housing 1. The housing 1 is provided with a vertical slide 11 that matches the end of the dynamic pressure roller. The dynamic pressure roller is arranged horizontally and perpendicular to the movement direction of the inclined driving member 3. The vertical slide 11 provides a stable lifting trajectory for the dynamic pressure roller, and also plays a role of limiting and blocking the dynamic pressure roller. The structure design is simple and easy to install and disassemble; the dynamic pressure roller is generally a cylindrical structure, and the contact area between the dynamic pressure roller and the lower surface of the coiled steel belt 2 is relatively small. In the process of the coiled steel belt 2 moving and absorbing energy, the friction loss between the dynamic pressure roller and the coiled steel belt 2 is relatively small, which significantly extends the service life of the coiled steel belt 2. The fixed pressure unit 5 is two fixed pressure rollers, which are made of 45# steel. Both ends of the fixed pressure roller are installed on the inner wall of the housing 1. Two fixed pressure rollers are provided and are arranged at intervals on the same horizontal plane. The dynamic pressure roller is located between the two fixed pressure rollers, and the fixed pressure roller is parallel to the dynamic pressure roller. Two fixed pressure rollers and one dynamic pressure roller can better squeeze the local coiled steel belt 2 and deform it into a curved state, making the braking more stable; the fixed pressure roller is generally a cylindrical structure, and the contact area between the fixed pressure roller and the upper surface of the coiled steel belt 2 is relatively small. During the process of the coiled steel belt 2 moving and absorbing energy, the friction loss between the fixed pressure roller and the coiled steel belt 2 is relatively small, which significantly extends the service life of the coiled steel belt 2. Figure 3 and Figure 4The inclined plane driving member 3 includes a sliding block 31, a traction rod 32 and a core rod 33. The inclined plane 311 is arranged on the sliding block 31. A traction groove 312 is arranged in the sliding block 31. The traction rod 32 includes a rod portion and a protrusion. One end of the rod portion is connected to the connecting member 7, and the protrusion is arranged at the end of the rod portion away from the connecting member 7; a pit is arranged on the inner side wall of the traction groove 312, and mutually fitting occlusal slopes are arranged in the pit and on the surface of the protrusion. The inclination angle of the occlusal slope is 30°. The width of the traction groove 312 is equal to the sum of the diameter of the core rod 33 and the diameter of the rod portion. The end of the core rod 33 away from the traction rod 32 is welded and installed on the shell 1; when the dynamic pressure unit 4 moves to the highest position, the traction rod 32 can be separated from the traction groove 312. When the traction rod 32 moves with the traction member 6, the sliding block 31 moves with the traction rod 32 in the early stage because the protrusion engages with the inclined surface of the pit and the core rod 33 abuts against the traction rod 32; when the dynamic pressure unit 4 moves to the highest position, the traction rod 32 slides to a position where it cannot contact the core rod 33, and then the traction rod 32 can be separated from the traction groove 312, and the traction member 6 automatically unhooks after braking. The structure is simple and practical. Two spaced and horizontally arranged slide rails 12 are provided on the inner bottom wall of the shell 1. The slide rails 12 are parallel to the movement direction of the traction member 6, and a slide groove matching the slide rails 12 is provided at the bottom of the sliding block 31. The sliding cooperation between the slide rails 12 and the slide groove improves the stability of the sliding block 31 when it slides inside the shell 1, which is beneficial for the inclined surface 311 of the sliding block 31 to drive the dynamic pressure unit 4 to rise stably, and the above-mentioned structure is simple in design, which is convenient for installation and subsequent maintenance. Figure 2 and Figure 5, the top surface of the sliding block 31 is set as a plane 313, and the plane 313 is used to support the bottom of the dynamic pressure unit 4. When the dynamic pressure unit 4 is driven to the highest position by the inclined surface 311, the bottom of the dynamic pressure unit 4 contacts the above-mentioned plane 313. Due to the bending and the coiled steel belt 2 in the energy absorption process, it has a large downward pressure on the dynamic pressure unit 4. If there is no above-mentioned plane 313, this downward pressure will produce a horizontal force that drives the sliding block 31 to move in the opposite direction under the action of the inclined surface 311. Therefore, the above-mentioned plane 313 can effectively prevent the sliding block 31 from resetting in the opposite direction, and the whole structure is more stable and firm, and the safety is higher. An arc groove 314 is set on the plane 313, and the maximum depth of the arc groove 314 is 2 cm. The arc groove 314 can make the dynamic pressure unit 4 more stable on the plane 313, so that the coiled steel belt 2 can always maintain a bent state, and the braking effect is better. It also includes a limiting roller 8 fixedly installed inside the housing 1, and the connection between the traction member 6 and the coiled steel belt 2 is on the same horizontal plane as the bottom of the limiting roller 8. The limiting roller 8 can keep the section of the coiled steel belt 2 adjacent to the traction member 6 in a horizontal state, which is conducive to the traction member 6 to stably drive the coiled steel belt 2 to move, and is safer. The traction member 6 is a U-shaped shackle, and the U-shaped shackle is provided with a clamping plate 61 for clamping the movable end of the coiled steel belt 2, and the clamping plate 61 is attached to the lower surface of the coiled steel belt 2. The U-shaped shackle is a commonly used accessory, easy to purchase, low cost, small in size and large in load-bearing weight. The contact area between the clamping plate 61 and the movable end of the coiled steel belt 2 is relatively large, and the connection between the movable end of the coiled steel belt 2 and the U-shaped shackle is more secure. The connecting member 7 is a steel wire rope or a lifting belt. The steel wire rope or the lifting belt has high tensile strength, fatigue resistance and impact toughness, good softness, suitable for traction and pulling, and is a commonly used accessory, easy to purchase, and low in cost. The implementation principle of the steel belt type energy absorption buffer brake device in the inclined lane transportation of the embodiment of the present application is: when the traction member 6 is forced to move, the coiled steel belt 2 and the inclined plane driving member 3 connected thereto move together. When the inclined plane driving member 3 moves, the inclined plane 311 pushes the dynamic pressure unit 4 to move upward to cooperate with the fixed pressure unit 5 to squeeze part of the coiled steel belt 2, so that the coiled steel belt 2 is bent and deformed. The deformation process of the coiled steel belt 2 is the process of generating the braking force. The braking force changes from small to large and then reaches the maximum value, realizing the gradual loading of the braking force. The coiled steel belt 2 is installed in the shell 1 after coiling and forming, so as to achieve the effect of saving space. The coiled steel belt 2 can be set to be very long due to the coiling and forming, so that the braking force is continuously output. The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
