Description

Technical Field

[0001] The present invention relates to the technical field of anchor cable transportation, and particularly relates to a coal mine anchor cable transportation device. Background Art

[0002] A coal mine anchor cable transport vehicle is a device for transporting anchor cables in a mine roadway. Since the mine roadway is relatively narrow, the anchor cables need to be bent to adapt to the narrow mine roadway.

[0003] However, during the bending process of the anchor cable, stress concentration will occur at the bending part. Due to vibrations during transportation, the stress at the bending part will show an irregular distribution, resulting in stress shear at the bending part of the anchor cable. During long-term transportation, the anchor cable is in a vibrating environment for a long time, which easily causes damage to the bending part of the anchor cable. Especially when there are large pits or bumps on the road surface, large vibrations will occur. When large vibrations occur, the stress at the bending part of the anchor cable will surge, resulting in an increase in the stress shear strength, thereby making the bending part of the anchor cable more easily damaged. Summary of the Invention

[0004] The purpose of the present invention is to provide a coal mine anchor cable transportation device to solve the technical problem in the prior art that when there are large pits or bumps on the road surface, large vibrations will occur. When large vibrations occur, the stress at the bending part of the anchor cable will surge, resulting in an increase in the stress shear strength, thereby making the bending part of the anchor cable more easily damaged.

The elastic protrusions are arranged in a hexagonal honeycomb shape with a central depression, and air bags are symmetrically embedded at positions on both sides of the anchor cables on the elastic protrusions; A dynamic response assembly, which includes a pressure chamber and a counterweight. The counterweight is elastically arranged in the pressure chamber along the direction of inertial movement. The counterweight divides the pressure chamber into two sealed spaces, and any one of the sealed spaces is communicated with the two air bags; When large amplitudes occur, the instantaneous stress of the bent part of the cable anchor suddenly increases. Under the action of inertia, the counterweight slides along the pressure chamber, adjusting the air pressure compression in any enclosed space to inflate and deform the two airbags to the limit expansion state, so as to actively envelope and contact the cable anchor to form a three-dimensional stress dissipation channel.

[0006] Preferably, the support plate further includes elastic blocks, which are arranged in the gaps between adjacent contact plates and fixedly connected to the contact plates to form an alternating stress dispersion structure.

[0007] Preferably, weight shells are arranged in an array on the support shell, support arms are symmetrically arranged on the weight shells, and the support arms are connected to the contact plates through connecting rings.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0020] As Figures 1-10 shown, a coal mine anchor cable transportation device includes: A vehicle body 1, on the top of which there are symmetrically arranged U-shaped tracks 2 with a horizontal central axis, and the U-shaped tracks 2 are used to constrain a plurality of anchor cables to be arranged in a U-shaped bent shape; A dynamic support assembly, which includes an arc-shaped support shell 3 and an arc-shaped support plate 4 located at the bent part of the U-shaped track 2 and having a continuous curvature. The support plates 4 are arranged in a gap array along the width direction of the support shell 3. The support plate 4 includes contact plates 41 arranged at intervals, and the contact plates 41 are connected to the support shell 3 through connecting rings 11; An elastic protrusion 5, which is fixedly arranged on the contact surface of the contact plate 41 in contact with the anchor cable. The elastic protrusion 5 is arranged in a hexagonal honeycomb shape with a central depression, and airbags 51 are symmetrically embedded on both sides of the anchor cable on the elastic protrusion 5; A dynamic response assembly, which includes a pressure chamber 8 and a counterweight block 7. The counterweight block 7 is elastically arranged in the pressure chamber 8 along the direction of inertial movement. The counterweight block 7 divides the pressure chamber 8 into two closed spaces, and any one of the closed spaces is communicated with the two airbags 51; When a large amplitude occurs, the instantaneous stress at the bent part of the anchor cable suddenly increases. The counterweight block 7 slides along the pressure chamber 8 under the action of inertia, adjusts the air pressure compression of any one of the closed spaces, and makes the two airbags 51 inflate and deform to reach the limit expansion state, so as to actively envelope and contact the anchor cable to form a three-dimensional stress dissipation channel.

[0021] Specifically, the anchor cables are fixedly arranged in a U-shaped bent shape between the U-shaped tracks 2, thereby reducing the storage space of the anchor cables. The anchor cables are transported by the driving wheels at the bottom of the vehicle body 1, which is convenient for the transportation of the anchor cables in narrow coal mine roadways.

[0022] Furthermore, during the bending process of the cable anchor, stress concentration occurs at the bending part. Due to vibrations during transportation, the stress at the bending part will show an irregular distribution, resulting in stress shear at the bending part of the cable anchor. During long-term transportation, the cable anchor is in a vibrating environment for a long time, which easily causes damage to the bending part of the cable anchor. By providing the arc-shaped support shell 3 and arc-shaped support plate 4 with continuous curvature, the arc-shaped support plates 4 arranged in an array support the bending part of the cable anchor at the corresponding position, thereby dispersing the stress support for the bending part of the cable anchor, reducing the irregular stress distribution at the bending part of the cable anchor, thereby reducing the stress shear at the bending part of the cable anchor, and thus avoiding damage to the cable anchor during transportation due to being in a vibrating environment for a long time.

[0023] Furthermore, since the support plate 4 is composed of multiple contact plates 41 arranged with gaps, the bending part of the cable anchor at the corresponding position is supported dispersedly by the multiple contact plates 41, thereby forming an overall support for the bending part of the cable anchor macroscopically through continuous and dispersed rigid point supports for the bending part of the cable anchor. This can effectively avoid rigidly supporting the entire bending part, resulting in the entire bending part and the support part always being in contact and unable to transfer stress. When sudden irregular vibrations occur, if stress surges at a certain point and stress transfer cannot occur, it is easy for that point to be damaged. Through continuous and dispersed rigid point supports, stress is further evenly dispersed, further improving the support effect.

[0024] Furthermore, the contact plate 41 and the support shell 3 are connected by a connecting ring 11. During transportation, when sudden irregular vibrations occur, since the contact plate 41 and the support shell 3 are connected by the connecting ring 11, the contact plate 41 has a high degree of freedom of movement. Therefore, when sudden irregular vibrations occur, the contact plate 41 can make adaptive dynamic micro-angle adjustments, thereby better supporting the bending part of the cable anchor at the corresponding position and being able to better disperse stress adaptively according to the stress distribution, further improving the support and protection effect on the bending part of the cable anchor.

[0025] Furthermore, by providing elastic protrusions 5 on the contact surface between the contact plate 41 and the cable anchor, when the cable anchors are arranged in a U-shaped bent shape and fixed between the U-shaped tracks 2, the bending part of the cable anchor squeezes the elastic protrusions 5 to cause elastic deformation, thereby converting the rigid support of the contact plate 41 into the elastic support of the elastic protrusions 5, thereby providing prestress for the bending part of the cable anchor at the corresponding position. By providing the prestress, part of the stress at the bending part of the cable anchor can be offset, thereby weakening the stress shear generated by vibrations during transportation. At the same time, the elastic protrusions 5 can absorb the vibrations generated during transportation, effectively avoiding resonance damage to the bending part of the cable anchor, and further improving the support and protection effect on the bending part of the cable anchor.

[0026] Furthermore, by arranging the elastic protrusions 5 in a hexagonal honeycomb shape with a central depression, when supporting the bent part of the cable anchor, part of the bent part of the cable anchor sinks into the central depression of the elastic protrusions 5 and squeezes the elastic protrusions 5, thereby changing the linear support for the bent part of the cable anchor into a surface support, increasing the support area, and further improving the support effect.

[0027] Furthermore, during the transportation of the cable anchor, due to the rough road conditions of the transportation environment, when there are large pits or bumps on the road surface, the vehicle body 1 will vibrate greatly. When there is a large vibration, the stress of the bent part of the cable anchor will surge, resulting in an increase in the stress shear strength, making the bent part of the cable anchor more prone to damage. Therefore, when there is a large shock, the counterweight 7 moves along the pressure chamber 8 in the pressure chamber 8 due to inertia, and under the action of the first springs symmetrically arranged on both sides of the counterweight 7, it moves back and forth in the pressure chamber 8. When there is a large vibration, the counterweight 7 moves along the pressure chamber 8 to the farthest distance from the counterweight 7 and squeezes the first springs. At the same time, the air pressure in the sealed space where the first springs are located is compressed, thereby squeezing the gas in this sealed space into the two air bags 51, so that the two air bags 51 are inflated and deformed to reach the limit expansion state, to actively envelope and contact the cable anchor, to form a three-dimensional stress dissipation channel, and cooperate with the deformation absorption function of the honeycomb structure to achieve multi-stage dissipation of impact energy, thus effectively avoiding the stress surge of the bent part of the cable anchor when there is a large vibration, resulting in an increase in the stress shear strength and making the bent part of the cable anchor more prone to damage, and using the vibration inertia to drive the counterweight 7, without external energy, can achieve timely response, thereby realizing dynamic response to vibration changes, effectively improving the support effect on the bent part of the cable anchor during transportation, and effectively improving the transportation stability of the transportation device.

[0028] Furthermore, since the counterweight 7 divides the pressure chamber 8 into two sealed spaces, and any one of the sealed spaces is communicated with two air bags 51, when the internal air pressure of one of the sealed spaces is compressed, the other sealed space will be in a negative pressure state due to the increase in volume, and will draw out the gas in the air bag 51. Therefore, a square transition tube is provided for communication between the air bag 51 and the two sealed spaces. An activity plate is arranged inside it, and second springs are arranged on both sides of the activity plate. The activity plate divides the square transition tube into two cavities, and the two cavities are respectively communicated with the two sealed spaces through the first connecting pipes. A Y-shaped pipe communicated with the two air bags 51 is arranged on the side wall of the tube at the position of the activity plate. When the internal air pressure of one of the sealed spaces is compressed, the gas in this sealed space enters the cavity on the corresponding side in the square transition tube through the corresponding first connecting pipe, while the other sealed space is in a negative pressure state due to the increase in volume and draws the gas in the other cavity into this sealed space. At this time, the activity plate moves and compresses the second spring, connecting the air inlet of the Y-shaped pipe with the cavity on the inflation side and blocking the orifice between the cavity on the air extraction side and the connecting pipe, so that the gas can smoothly enter the air bag 51.

[0029] As a further embodiment provided by the present invention, the support plate 4 further includes an elastic block 42, which is arranged in the gap between two adjacent contact plates 41 and is fixedly connected with the contact plates 41 to form an alternating stress dispersion structure.

[0030] Specifically, by connecting the elastic block 42 in the gap between two adjacent contact plates 41, and arranging the rigid contact plates 41 and the elastic blocks 42 alternately, a dynamic stress dispersion structure is formed by using a staggered layout, which can be dynamically adjusted along with the stress change of the bending part of the anchor cable, and can restrict the dynamic adjustment of the contact plates 41 to avoid irregular adjustment of the contact plates 41, so as to better support the bending part of the anchor cable and further improve the support effect and the stability of the support.

[0031] As a further embodiment provided by the present invention, counterweight shells 6 are arranged in an array on the support shell 3, support arms 9 are symmetrically arranged on the counterweight shells 6, and the support arms 9 are connected with the contact plates 41 through connecting rings 11.

[0032] Specifically, the pressure chamber 8 is arranged in the counterweight shell 6, and the square transition tube is fixedly arranged on the outer wall of the counterweight shell 6.

[0033] As a further embodiment provided by the present invention, a piston 10 is elastically arranged in the support arm 9. The piston 10 is a double-layer piston plate structure, and a damping hole is arranged on one of the piston plates.

[0034] Specifically, when transporting the anchor cable on a relatively flat road section, the vibration amplitude is small. The piston 10 elastically arranged inside the support arm 9 is connected to the contact plate 41 through the connecting ring 11. The friction damping generated by the sliding of the piston 10 inside the support arm 9 and the action of the third spring are used for vibration reduction, thereby further weakening the influence of low-frequency vibration on the bent part of the anchor cable, further improving the stability of the anchor cable transportation, and ensuring that the anchor cable is not easily damaged during the transportation process.

[0035] As a further embodiment provided by the present invention, a partition is fixedly arranged inside the support arm 9, and the partition divides the inside of the support arm 9 into two sealed cavities.

[0036] Specifically, the two piston plates of the piston 10 are respectively located on both sides of the partition, and the sealed cavity where the piston plate provided with the damping holes is located is filled with a shear thickening fluid. By dividing the inside of the support arm 9 into two sealed cavities through the partition and making the two piston plates of the piston 10 be respectively located on both sides of the partition, when small-amplitude vibration occurs, the two piston plates move synchronously in the corresponding sealed cavities through the connecting rod. When the piston plate provided with the damping holes moves in the sealed cavity at the corresponding position, the gas moves back and forth on both sides of the piston plate in the corresponding sealed cavity through the damping holes. Thus, by restricting the fluid exchange rate, the piston damping holes allow the fluid to flow slowly, cooperate with the third spring to absorb energy, and further reduce the vibration of the contact plate 41, thereby further improving the stability of the contact plate 41 in supporting the bent part of the anchor cable.

[0037] Furthermore, by filling the sealed cavity where the piston plate provided with the damping holes is located with a shear thickening fluid, the shear thickening fluid is a non-Newtonian liquid and has the following two functions: When in low-frequency vibration, the piston damping holes allow the fluid to flow slowly, cooperate with the third spring to absorb energy, and further reduce the vibration of the contact plate 41, thereby further improving the stability of the contact plate 41 in supporting the bent part of the anchor cable.

[0038] When in high-frequency vibration, the non-Newtonian fluid solidifies, thereby rigidly supporting the contact plate 41. At the same time, due to inertia, the counterweight 7 moves along the pressure chamber 8 in the pressure chamber 8, and under the action of the first springs symmetrically arranged on both sides of the counterweight 7, it moves back and forth in the pressure chamber 8. When there is a large-amplitude vibration, the counterweight 7 moves along the pressure chamber 8 to the farthest distance from the counterweight 7 and squeezes the first springs. At the same time, the air pressure in the sealed space where the first springs are located is compressed, so that the gas in the sealed space is squeezed into the two air bags 51, so that the two air bags 51 are inflated and deformed to reach the limit expansion state, so as to actively envelope and contact the anchor cable to form a three-dimensional stress dissipation channel, and cooperate with the deformation absorption function of the honeycomb structure to realize the multi-stage dissipation of impact energy, thereby effectively avoiding the stress surge at the bending part of the anchor cable when there is a large-amplitude vibration, resulting in an increase in the stress shear strength and making the bending part of the anchor cable more likely to be damaged. Moreover, the vibration inertia is used to drive the counterweight 7, and without external energy, timely response can be achieved, so as to realize the dynamic response to vibration changes, effectively improve the support effect on the bending part of the anchor cable during transportation, and effectively improve the transportation stability of the transportation device.

[0039] Thus, it can dynamically adjust to the vibrations under different road conditions, dynamically support the bending part of the anchor cable from multiple dimensions, effectively improve the support and protection effect of the device on the anchor cable during transportation, and is suitable for long-term transportation.

[0040] As a further embodiment provided by the present invention, a first clamping assembly for driving the anchor cable to bend along the U-shaped track 2 is slidably arranged on the U-shaped track 2.

[0041] As a further embodiment provided by the present invention, a second clamping assembly for clamping and fixing the other end of the anchor cable is arranged on the vehicle body 1.

[0042] As a further embodiment provided by the present invention, both the first clamping assembly and the second clamping assembly include a frame, and electric push rods are symmetrically arranged at the top of the frame, and a pressing plate is fixedly connected to the output end of the electric push rod.

[0043] Specifically, pass multiple cable bolts through the second clamping assembly and the second clamping assembly. First, start the electric push rod at the top of the first clamping assembly to drive the pressure plate to press one end of the cable bolt tightly. Then, start the motor to drive the gear at the output end to rotate in the gear groove opened on the U-shaped track 2, thereby driving the first clamping group to slide along the U-shaped track 2, and driving the cable bolt to move along the U-shaped track 2 through the second clamping assembly, so that the cable bolts are fixedly arranged in a U-shaped bent shape between the U-shaped tracks 2. Then, start the second clamping assembly to clamp and fix the other end of the cable bolt. When unloading, first loosen the second clamping assembly, and then drive the motor to drive the other end of the cable bolt to move reversely along the U-shaped track 2, thereby automatically unloading the cable bolt without manual unloading, saving labor, and with the limitation of the first clamping assembly and the second clamping assembly, the cable bolt will not bounce off, improving the safety of the device during unloading.

[0044] As a further embodiment provided by the present invention, arc-shaped clamping grooves are respectively opened on the pressure plate and the inner wall of the bottom of the frame, and rubber layers are fixedly arranged on the arc-shaped clamping grooves.

[0045] Specifically, the friction force with the cable bolt is further increased through the provided rubber layer, so as to fix the cable bolt more stably.

[0046] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
