Description

Technical Field

[0001] The invention belongs to the field of geological disaster management, and specifically relates to a conveying structure for geological disaster management. Background Art

[0002] Geological disasters refer to events that damage human life, property and living environment due to natural or human factors. Geological disasters mainly include collapse (i.e. dangerous rock mass), landslides, debris flows, karst ground collapse and ground fissures. Especially in mountainous areas, due to the special geological structure and geographical environment, the frequency of geological disasters is relatively high. After a geological disaster occurs, the speed of delivery of disaster relief materials (including but not limited to food, drinking water, construction materials, etc.) largely determines the rescue effect, and how to quickly establish a delivery channel is the difficulty of geological disaster management.

[0003] Based on this, a simple and convenient conveying structure is needed for the transportation of materials after geological disasters. Summary of the invention

[0004] In order to solve the problem that materials are difficult to transport when geological disasters occur, the present invention provides a conveying structure for geological disaster management. A conveying structure with a simple structure and convenient operation is designed by using the principle of a zipline structure, so as to facilitate the transportation of materials after a geological disaster occurs, thereby improving the rescue effect.

[0005] In order to solve the technical problem, the technical solution adopted by the present invention is:

[0006] A conveying structure for geological disaster control, characterized in that it includes a column, a base is arranged below the column, and at least three supporting fixings are also arranged on the column above the base. The base and / or the supporting fixings are used to stabilize the column on the ground. A driving motor is fixedly installed on the upper end of the column, and a rotating shaft is also installed on the column. The driving motor drives the rotating shaft to rotate through a belt. A conveying wheel is sleeved on the rotating shaft, and a slide rope is sleeved on the outer periphery of the conveying wheel. The other side of the slide rope is sleeved on the conveying wheel of another conveying structure for geological disaster control with the same structure, and a material box is installed on the slide rope.

[0007] In some embodiments, the support fixing member includes a pin seat arranged at the periphery of the column, the pin seat is sleeved with a pin, a support arm is rotatably connected to the pin, and a soil nail is arranged at one end of the support arm away from the pin. In the specific implementation process, each support fixing member is evenly distributed at the periphery of the column.

[0008] In some embodiments, a blind hole is opened at the top of the column, at least two bearings are installed in the blind hole, and the rotating shaft is fixedly installed in the bearings in the blind hole; a reinforcing shell is arranged around the top area of ​​the column.

[0009] In some embodiments, a limiting portion for setting the sling sleeve on the conveying wheel is detachably mounted on the top of the column through a support member.

[0010] In some embodiments, the limiting portion includes a main body, which has an installation cavity, in which a sliding block capable of sliding in the installation cavity is installed, a horizontally arranged through hole is opened on the side of the main body facing the conveying wheel, the sliding block has an inclined surface, an extrusion block is sleeved in the through hole, and the extrusion block has an inclined surface that matches the inclined surface of the sliding block on the side facing the sliding block, and when the sliding block moves upward in the installation cavity, it drives the extrusion block away from the main body and thus extrude the rope wrapped around the conveying wheel; the lower end of the sliding block is connected to an L-shaped rotating rod, the rotating rod is hinged to the main body, one end of the rotating rod is connected to the lower end of the sliding block, the middle area of ​​the rotating rod is hinged to the main body, the other end of the rotating rod is connected to a lifting arm, and the upper end of the lifting arm is rotatably connected to a roller shaft supported under the rope; the upper end of the sliding block is installed with a reset piece made of an elastic element.

[0011] Wherein, the body comprises an arc-shaped outer body and an end cover, the end cover and the outer body form a mounting cavity, and the through hole is provided on the end cover.

[0012] In some embodiments, the outer body is provided with a through hole for steel bars or anchor cables to pass through, one side of the through hole matches the inner diameter of the groove of the conveying wheel, and the width of the through hole matches the depth of the groove of the conveying wheel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When the present invention uses two conveying structures for geological disaster management with the same structure to transport materials, the rotation directions of the driving motors on the two conveying structures for geological disaster management with the same structure are the same, so that the two driving motors are used to synchronously drive the rotating shaft to rotate and synchronously drive the conveying wheel to rotate, and then the static friction between the conveying wheel and the zipline is used to drive the zipline to rotate, and finally drive the material box to reciprocate on the conveying wheels on the two conveying structures, thereby realizing the transportation of materials. The present invention uses two conveying structures for geological disaster management with the same structure to jointly form a temporary zipline conveying structure for material transportation, which can be used to transport rescue materials after a geological disaster occurs, and the structure itself is relatively simple and easy to operate, which is particularly suitable for geological disaster management in mountainous areas. At the same time, the present invention can selectively install two conveying structures for geological disaster management with the same structure at the same height or at different heights according to the actual situation on site, so that both plane transportation and material transportation along the slope can be carried out.

[0015] During use, the limit part of the present invention increases the weight of the material in the material box, so that the downward inclination angle of the slide cable increases, so that it contacts the roller shaft and gradually squeezes the roller shaft. When the roller shaft moves downward, it drives the lifting arm to move downward, and then drives the rotating rod pin shaft to rotate. When the rotating rod rotates, it drives the sliding block to move upward. When the sliding block moves upward, it drives the squeezing block to move toward the conveying wheel to squeeze the slide cable, thereby increasing the static friction between the slide cable and the conveying wheel. On the one hand, it prevents the relative sliding between the slide cable and the conveying wheel due to the increase of the weight of the material box and the lack of static friction between the guide slide cable and the conveying wheel, which makes it impossible to convey the material box. On the other hand, since the squeezing block can increase the static friction between the slide cable and the conveying wheel, it can also appropriately reduce the vibration of the slide cable on the conveying wheel.

[0016] When the conveying wheel is not equipped with a sliding cable, the steel bar (or anchor cable) used for construction is inserted into the conveying wheel and passed through the insertion hole. When the conveying wheel rotates, the friction between the steel bar and the conveying wheel can drive the steel bar to move, thereby achieving the traction and dragging of the steel bar (or anchor cable). That is to say, the conveying structure of the present invention can not only use the material box on the sliding cable to transport materials, but also traction the steel bar (or anchor cable), reducing the labor intensity of the staff during the treatment process.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the scope of protection of the present invention.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In conjunction with the accompanying drawings, the conveying structure for geological disaster control of the present invention includes a column 1, a base 101 is arranged below the column 1, and at least three supporting fixings 3 are also arranged on the column 1 above the base 101. The base 101 and / or the supporting fixings 3 are used to stabilize the column 1 on the ground. A driving motor 5 is fixedly installed on the upper end of the column 1, and a rotating shaft 51 is also installed on the column 1. The driving motor 5 drives the rotating shaft 51 to rotate through a belt 54. A conveying wheel 55 is sleeved on the rotating shaft 51, and a sliding rope 8 is sleeved on the outer periphery of the conveying wheel 55. The other side of the sliding rope 8 is sleeved on the conveying wheel 55 of another conveying structure for geological disaster control with the same structure, and a material box 2 is installed on the sliding rope 8.

[0025] In the specific implementation process, in order to facilitate the transportation of the material box 2, a roller 201 is provided at the bottom of the material box 2. In some implementations, a support rod 204 is provided in the middle of the material box 2, and a clamping block 202 is sleeved on the sling 8. A hook 203 that is compatible with the support rod 204 is installed at the lower end of the clamping block 202, so that the entire material box 2 is hung on the hook by using the support rod 204. When it is necessary to take out materials from the material box 2, the material box 2 can be turned over to take out the materials. In some embodiments, the material box 2 is equipped with an opening and closing door, which is used to facilitate the placement and removal of materials. Therefore, in the actual process of conveying materials, the staff can make a choice according to the specific situation of the materials.

[0026] The present invention utilizes two conveying structures for geological disaster management with the same structure to jointly form a temporary zipline conveying structure for material transportation. After a geological disaster occurs, the conveying structure can be used to transport rescue materials. The structure itself is relatively simple and easy to operate, and is particularly suitable for geological disaster management in mountainous areas. At the same time, the present invention can selectively install two conveying structures for geological disaster management with the same structure at the same height or at different heights according to the actual situation on site, so that both plane transportation and material transportation along the slope can be achieved.

[0027] When using two conveying structures with identical structures for geological disaster control to transport materials, the driving motors on the two conveying structures with identical structures for geological disaster control have the same rotation direction, so that the two driving motors are used to synchronously drive the rotating shaft to rotate, and then synchronously drive the conveying wheels to rotate, and then use the static friction between the conveying wheels and the slide rope to drive the slide rope to rotate, and finally drive the material box to reciprocate on the conveying wheels on the two conveying structures, thereby realizing the transportation of materials.

[0028] In the specific implementation process, the support fixture 3 and the base 101 can be set according to actual conditions. For example, at the beginning of the rescue, when relatively light materials such as food and water need to be transported first, the support fixture 3 can be directly used to support the entire conveying structure. As the material preparation becomes more and more complete, when relatively heavy materials need to be prepared for construction, the base 101 or the base 101 and the support fixture 3 are used together to support the entire conveying structure to improve the stability of the entire conveying structure when transporting relatively heavy materials.

[0029] Among them, a number of through holes are opened on the base 101, an anchoring platform is cast on the ground, and embedded screws are implanted in the anchoring platform. The embedded screws pass through the through holes on the base 101 and are locked by locking nuts, thereby locking the base 101 on the anchoring platform, thereby ensuring the stability of the entire conveying structure.

[0030] During the specific implementation process, a driving pulley 52 is installed on the output shaft of the driving motor 5, and a driven pulley 53 is installed on the periphery of the rotating shaft 51. When the driving motor 5 drives the driving pulley 52 to rotate, the driving pulley 52 drives the driven pulley 53 to rotate through the belt 54, thereby driving the rotating shaft 51 to rotate.

[0031] In some embodiments, the support fixing member 3 includes a pin seat 301 disposed on the periphery of the column 1, a pin 302 is sleeved on the pin seat 301, a support arm 303 is rotatably connected to the pin 302, and a soil nail 304 is provided at one end of the support arm 303 away from the pin 302. In the specific implementation process, each support fixing member 3 is evenly distributed on the periphery of the column 1. That is, the soil nail 304 is inserted into the rock and soil body for fixing.

[0032] In some embodiments, a blind hole is provided at the top of the column 1, at least two bearings are installed in the blind hole, and the rotating shaft 5 is fixedly installed in the bearings in the blind hole. In the specific implementation process, since the blind hole will reduce the structural strength of the top area of ​​the column, a reinforcing shell 4 can be provided on the periphery of the top area of ​​the column 1 to strengthen the top area of ​​the column 1.

[0033] Among them, as a preferred mode of the present invention, the drive motor 5 is installed in the reinforced housing 4, and the drive motor is protected by the reinforced housing 4. In the specific implementation process, the upper and lower ends of the reinforced housing 4 corresponding to the position of the drive motor 5 are both opened, which is convenient for the installation of the driving pulley and the belt on the one hand, and for the heat dissipation of the drive motor on the other hand.

[0034] In some embodiments, a limiting portion 7 for sleeve-mounting the sliding cable 8 on the conveying wheel 55 is detachably mounted on the top of the column 1 through a supporting member 6 , that is, the supporting member 6 serves to install the limiting portion 7 .

[0035] In some embodiments, the limiting portion 7 includes a body, the body has an installation cavity 73, a sliding block 74 capable of sliding in the installation cavity is installed in the installation cavity, a horizontally arranged through hole is opened on the side of the body facing the conveying wheel 55, the sliding block 74 has an inclined surface, an extrusion block 75 is sleeved in the through hole, and the extrusion block 75 has an inclined surface that matches the inclined surface of the sliding block 74 on the side facing the sliding block 74, and the sliding block 74 drives the extrusion block 75 away from the inclined surface when moving upward in the installation cavity The main body then squeezes and wraps the slide rope 8 on the conveying wheel 55; the lower end of the sliding block 74 is connected to an L-shaped rotating rod 76, and the rotating rod 76 is hinged on the main body, one end of the rotating rod 76 is connected to the lower end of the sliding block 74, and the middle area of ​​the rotating rod 76 is hinged on the main body, and the other end of the rotating rod 76 is connected to a lifting arm 77, and the upper end of the lifting arm 77 is rotatably connected to a roller shaft 78 supported under the slide rope 8; the upper end of the sliding block 74 is installed with a reset member 79 made of an elastic element.

[0036] The working process of the limiter of the present invention is as follows: with the increase of the weight of the material in the material box, the downward tilt angle of the slide cable increases, so that it contacts the roller shaft and gradually squeezes the roller shaft. When the roller shaft moves downward, it drives the lifting arm to move downward, and then drives the rotating rod pin shaft to rotate. When the rotating rod rotates, it drives the sliding block to move upward. When the sliding block moves upward, it drives the squeezing block to move toward the conveying wheel to squeeze the slide cable, thereby increasing the static friction between the slide cable and the conveying wheel. On the one hand, it prevents the slide cable and the conveying wheel from sliding relative to each other due to the increase of the weight of the material box and the lack of static friction between the guide slide cable and the conveying wheel, and the problem of being unable to convey the material box. On the other hand, since the squeezing block can increase the static friction between the slide cable and the conveying wheel, it can also appropriately reduce the vibration of the slide cable on the conveying wheel. When the weight of the material box is reduced (or unloaded), the downward pulling force on the slide cable is reduced, so that the slide cable and the roller shaft are separated from each other, and the sliding block is driven downward under the reset action of the reset member, so that the squeezing block retracts into the body, and the lifting arm moves upward to reset.

[0037] In the specific implementation process, a limiting boss is arranged on the periphery of the extrusion block, and a limiting cylinder is arranged on the body corresponding to the position of the through hole. The size of the limiting boss is larger than that of the limiting cylinder. A reset spring is sleeved between the limiting boss and the side wall of the body. Under the action of the reset spring, the extrusion block can be driven to retract into the body, so that the extrusion block and the anchor cable on the conveying wheel are separated from each other. The limit position of the extrusion block can be limited by the cooperation between the limiting boss and the limiting cylinder, and the limiting cylinder also provides a accommodating cavity for the spring.

[0038] The main body includes an arc-shaped outer body 71, and the outer body 71 is equipped with an end cover 72. The end cover 72 and the outer body 71 form a mounting cavity 73. The through hole is opened on the end cover 72, that is, the extrusion block 75 passes through the end cover 72 and is used to contact the slide rope 8 on the conveying wheel 55.

[0039] In some embodiments, the outer body 71 is provided with a through hole 710 for the steel bar 9 or the anchor cable to pass through, one side of the through hole 710 matches the inner diameter of the groove of the conveying wheel 55, and the width of the through hole 710 matches the depth of the groove of the conveying wheel 55. In the specific implementation process, when the slip rope 8 is not installed on the conveying wheel 55, the steel bar (or anchor cable) used for construction is inserted into the conveying wheel 55 and passes through the through hole 710. When the conveying wheel 55 rotates, the friction between the steel bar 9 and the conveying wheel 55 can drive the steel bar 55 to move, thereby achieving the traction and dragging of the steel bar 9 (or anchor cable). That is to say, the conveying structure of the present invention can not only use the material box 2 on the slip rope 8 to convey materials, but also traction the steel bar 9 (or anchor cable), reducing the labor intensity of the staff during the treatment process.

[0040] In the specific implementation process, in order to reduce the wear on the insertion hole 710 and improve the static friction between the inserted steel bar 9, a wear-resistant and anti-skid layer is arranged around the insertion hole 710.

[0041] Among them, since the insertion hole 710 on the outer body 71 is opened on one side of the conveying wheel 55, the position of the installation cavity 73 should be staggered with the position of the insertion hole 71, and at the same time, the size of the extrusion block 75 is maximized to increase the static friction between the extrusion block 75 and the slide cable 8. In the specific implementation process, the extrusion block 75 is set in an arc shape so that it can contact the slide cable 8 more. The side of the extrusion block 75 facing the slide cable is arranged with a wear-resistant and anti-skid layer to reduce the wear on the slide cable 8 and increase the static friction between the slide cable 8.

[0042] In the specific implementation process, the wear-resistant and anti-skid layer can be made of rubber.
