Description

Technical Field

[0001] This invention relates to the field of emergency rescue technology, and more specifically, to a bulldozing device and method for rapidly establishing rescue channels. Background Technology

[0002] Frequent natural disasters cause severe casualties and enormous economic losses. Emergency rescue is a crucial measure to safeguard people's lives and property, maintain social stability, and promote post-disaster recovery and reconstruction after a natural disaster.

[0003] In the critical moments of emergency rescue, disaster areas often face communication and road disruptions. Road closures prevent rescue vehicles and equipment, such as cranes, fire trucks, and ambulances, from reaching the affected areas. Urgently needed relief supplies, such as food, medicine, and tents, cannot be delivered in a timely manner, severely impacting the basic living conditions and medical treatment of the affected people. Furthermore, road damage increases the difficulty and risk for rescuers to enter the disaster area on foot. Rescue workers not only have to carry heavy equipment but also overcome harsh terrain conditions, which undoubtedly reduces the efficiency of the rescue efforts.

[0004] Currently, when establishing rescue channels in disaster areas, multi-functional emergency rescue vehicles are used to push out the rescue channels. However, when the loaders integrated on these multi-functional emergency rescue vehicles are removing road obstacles (such as mud and rock mixtures and soil), they often need to be moved after the bucket is full. This process requires adjusting the vehicle's posture and the position of the bucket, which makes it impossible to further improve the efficiency of obstacle removal. Summary of the Invention

[0010] As a further optimization of the present invention, the extrusion assembly includes a screw conveyor assembly movably connected to the inner wall of the first bucket body, a speed changer and a protective cover detachably connected to one side wall of the second bucket body, and a motor connected to the speed changer. The speed changer and the motor are both located within the coverage area of ​​the protective cover. The output end of the speed changer is connected to the screw conveyor assembly, and the output end of the motor is connected to the input end of the speed changer. A discharge chute is provided on the other side wall of the second bucket body, and the discharge chute communicates with the internal space of the second bucket body.

[0011] As a further optimization of the present invention, the interception component includes a filter plate connected to the second opening of the bucket body and an interception plate fixedly connected to the spiral conveying component, wherein the interception plate is distributed perpendicularly to the spiral conveying component.

[0012] As a further optimization of the present invention, the anti-blocking component includes a pusher plate slidably connected to the interceptor plate, a screw movably connected to the interceptor plate, a second motor fixedly installed on the interceptor plate, a first gear fixedly connected to the output end of the second motor, and a second gear fixedly connected to the screw. The pusher plate is threadedly connected to the screw, and the first gear meshes with the second gear.

[0013] As a further optimization of the present invention, the hydraulic boom assembly three includes a fixed bogie fixedly mounted on the vehicle body, a movable bogie movably connected to the fixed bogie, two sets of hydraulic cylinders four mounted on the vehicle body, a boom two movably connected to the movable bogie, a hydraulic cylinder five connected between the boom two and the movable bogie, a boom three movably connected to the boom two, a hydraulic cylinder six connected between the boom two and the boom three, and a hydraulic cylinder seven connected between the boom three and the bucket.

The extrusion assembly discharges the obstacles that have been filtered by the interception assembly into the assembled bucket assembly through the set channel to the area on the side of the travel path. The anti-blocking assembly sweeps the obstacles filtered on the interception assembly to the area on the side of the travel path. Step 4: When an obstacle with a volume exceeding the set threshold appears on the current travel path, the obstacle is broken, lifted, or excavated by an excavation mechanism.

[0016] The beneficial effects of this invention are as follows: This invention adopts an integrated design of a continuous bulldozing mechanism, an excavation mechanism, and a vehicle body to advance the rescue road along a set movement path. During the advancement process, the continuous bulldozing mechanism quickly removes obstacles on the path. This process does not require frequent adjustments to the position of the bulldozer bucket. Furthermore, the removed obstacles, such as soil, can be formed into mud strips of appropriate density under the action of the extrusion component and cover the obstacles on the corresponding sides of the rescue road. This can effectively cover and adhere to the side obstacles, thereby improving the stability of the rescue road and effectively blocking or mitigating the continued movement of side obstacles onto the rescue road.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed merely to enable those skilled in the art to better understand and implement the subject matter described herein. Furthermore, features described in some examples may be combined in other examples.

[0020] like Figures 1 to 9 As shown, a bulldozing device for rapidly establishing rescue channels includes: Vehicle body 1; The continuous bulldozing mechanism 2 includes a hydraulic boom assembly 1 mounted on the vehicle body 1, a modular bucket assembly movably connected to the hydraulic boom assembly 1, a hydraulic boom assembly 2 connected between the hydraulic boom assembly 1 and the modular bucket assembly, an extrusion assembly and an interception assembly mounted on the modular bucket assembly, and an anti-blocking assembly mounted on the interception assembly. The hydraulic boom assembly 1 is used to drive the modular bucket assembly to rotate around the movable connection between the hydraulic boom assembly 1 and the vehicle body 1 by a set angle. The hydraulic boom assembly 2 is used to drive the modular bucket assembly to rotate around its movable connection with the hydraulic boom assembly 1 by a set angle. The extrusion assembly is used to expel obstacles entering the modular bucket assembly from a set channel. The excavating mechanism 3 includes a hydraulic boom assembly 3 mounted on the vehicle body 1 and a bucket 308 mounted on the hydraulic boom assembly 3.

[0021] A limiting support mechanism 4 is installed on the vehicle body 1. The limiting support mechanism 4 includes several fixed limiting frames 401 fixedly installed on the vehicle body 1, a movable support frame 402 slidably installed on the fixed limiting frames 401, and a hydraulic cylinder 8 connected between the fixed limiting frames 401 and the movable support frame 402. The hydraulic cylinder 8 is used to drive the movable support frame 402 to move along the length direction of the fixed limiting frames 401.

[0022] It should be noted that the method of quickly establishing a rescue passage using the bulldozing device described above includes the following steps: Step 1: The vehicle body 1 carries the continuous bulldozing mechanism 2 and the excavating mechanism 3 to the starting point of the set travel path. Step 2: Control the bottom surface of the assembled bucket assembly to fit the road surface through hydraulic boom assembly 1 and hydraulic boom assembly 2, and drive the assembled bucket assembly along the set travel path through vehicle body 1. Step 3: Activate the extrusion and anti-blocking components. The extrusion component discharges obstacles filtered by the interception component into the assembled bucket assembly through a designated channel to the area on the corresponding side of the travel path. The anti-blocking component sweeps the obstacles filtered on the interception component to the area on the corresponding side of the travel path. The soil or mud-stone mixture extruded by the extrusion component has a certain viscosity and density and is extruded in a designated shape. The extruded soil or mud-stone mixture covers the remaining obstacles on the corresponding side of the road, such as soil, stones, tree debris, and other structures, forming a covering layer or flowing into the gaps of the corresponding structures to create an adhesive or covering effect. This allows for greater adhesive forces between the remaining obstacles on the side, preventing or hindering untreated obstacles from continuing to slide onto the established rescue road in subsequent processes. Step 4: When an obstacle with a volume exceeding the set threshold appears on the current travel path, the obstacle is broken, lifted, or excavated by the excavation mechanism 3. During this process, the limiting support mechanism 4 can provide auxiliary support to keep the vehicle body 1 stable.

[0023] In an optional embodiment of the invention, such as Figure 1 , Figure 2 and Figure 7 As shown, the hydraulic boom assembly includes two booms 201 movably connected to the vehicle body 1 and a hydraulic cylinder 202 connected between the booms 201 and the vehicle body 1. The two booms 201 are symmetrically distributed on the vehicle body 1, and the two ends of the hydraulic cylinder 202 are movably connected to the vehicle body 1 and the booms 201, respectively.

[0024] It should be noted that when adjusting the position of the assembled bucket assembly, the boom 201 can be rotated around the connection point with the vehicle body 1 in a set direction and at a set angle by the hydraulic cylinder 202. During this rotation, the assembled bucket assembly can move on the arc-shaped movement path set outside the vehicle body 1, so that the assembled bucket assembly can contact the ground or move to a set height position.

[0025] In an optional embodiment of the invention, such as Figure 1 , Figures 5 to 8 As shown, the modular bucket assembly includes a bucket body 208, a bucket body 209 movably connected to the bucket body 208, and a hydraulic cylinder 210 connected between the bucket body 208 and the bucket body 209. The hydraulic cylinder 210 is used to drive the bucket body 209 to rotate around the movably connected point with the bucket body 208 by a set angle. The bucket body 208 is movably connected to the other end of the boom 201.

[0026] It should be noted that, as mentioned above, when the assembled bucket assembly is in contact with the ground or has a set gap with the ground, it mainly controls the bottom of bucket body 209 to contact the ground or move to the height of the set gap with the ground. At this time, bucket body 209 and bucket body 208 are assembled into a complete bucket. After passing through the interception component, the soil or mud-stone mixture enters between bucket body 208 and bucket body 209, and under the continuous extrusion force of the extrusion component, it is extruded from the corresponding extrusion channel on bucket body 209. The extruded soil or mud-stone mixture is then laid out in a shaped manner on the ground. On the obstacles on the corresponding side of the rescue road, a stable covering layer is formed or gaps are filled to form an adhesive effect. When it is necessary to clear the space between bucket body 209 and bucket body 208, the hydraulic cylinder 3210 can drive bucket body 209 to rotate around the movable connection with bucket body 208, so that bucket body 209 and bucket body 208 switch from the contact state to the funnel shape with bottom leakage, so that the soil or mud-stone mixture accumulated at the bottom junction of bucket body 209 and bucket body 208 can be automatically removed or cleaned by manual / manual auxiliary equipment.

[0027] In an optional embodiment of the invention, such as Figure 1 , Figure 2 and Figure 7As shown, the hydraulic boom assembly 2 includes a connecting frame 1 203 and a connecting frame 3 205 movably connected to the boom 1 201, a connecting frame 204 connected between the connecting frame 1 203 and the vehicle body 1, a connecting frame 4 206 connected between the connecting frame 3 205 and the bucket body 1 208, and a hydraulic cylinder 207 connected between the connecting frame 1 203 and the connecting frame 3 205. The two ends of the connecting frame 204 are movably connected to the vehicle body 1 and the connecting frame 1 203, respectively. The two ends of the hydraulic cylinder 207 are movably connected to the connecting frame 1 203 and the connecting frame 3 205, respectively. The other end of the connecting frame 4 206 is movably connected to the bucket body 1 208.

[0028] It should be noted that, as mentioned above, when adjusting the rotation of the bucket body 208 around the movable connection with the boom 201 to change the angle at which the bucket body 209 contacts the ground or coincides with / cuts into the horizontal plane at a set height, the hydraulic cylinder 207 can drive the connecting frame 305 to rotate around the movable connection with the boom 201. When the connecting frame 305 rotates, the connecting frame 406 can rotate synchronously. When the connecting frame 406 follows the rotation of the connecting frame 305, its other end can drive the bucket body 208 to rotate around the movable connection with the boom 201.

[0029] In an optional embodiment of the invention, such as Figure 5 and Figure 6 As shown, the extrusion assembly includes a screw conveyor assembly 211 movably connected to the inner wall of bucket body one 208, a speed changer 212 and a protective cover 214 detachably connected to one side wall of bucket body two 209, and a motor one 213 connected to the speed changer 212. The speed changer 212 and the motor one 213 are both located within the coverage area of ​​the protective cover 214. The output end of the speed changer 212 is connected to the screw conveyor assembly 211, and the output end of the motor one 213 is connected to the input end of the speed changer 212. A discharge chute 215 is provided on the other side wall of bucket body two 209, and the discharge chute 215 communicates with the internal space of bucket body two 209.

[0030] It should be noted that, as mentioned above, when the soil or mud-stone mixture enters the area between bucket 1 208 and bucket 2 209, motor 1 213 drives the screw conveyor assembly 211 to rotate through speed changer 212. When the screw conveyor assembly 211 rotates, the soil or mud-stone mixture entering between bucket 1 208 and bucket 2 209 can be directionally discharged to the area distributed in the discharge chute 215. Under the action of extrusion pressure, it is continuously discharged from the discharge chute 215. During this process, the soil or mud-stone mixture can be stirred, so that the density and distribution uniformity of the finally discharged soil or mud-stone mixture can be higher than the initial loose state. The formed soil or mud-stone mixture covers the corresponding obstacles or enters the gaps between the obstacles in a set shape to form an adhesive effect.

[0031] In an optional embodiment of the invention, such as Figure 5 As shown, a detachable extension channel is installed at the discharge chute 215. The structure of the extension channel can be adaptively designed according to the current distribution of obstacles on the side of the road. The internal space of the extension channel is connected to the discharge chute 215. The squeezed-out soil or mud-rock mixture is discharged to the corresponding location through the discharge chute 215 and the extension channel. The discharge chute 215 faces the disaster area, such as the location of a mudslide collapse. If there is still a possibility that the obstacles in the area between the rescue road and the collapse site may continue to slide, the stability of the rescue road can be effectively improved in the subsequent process by forming an interception line composed of soil or mud-rock mixture with a certain interception capacity and the original obstacles on the corresponding side of the rescue road.

[0032] In an optional embodiment of the invention, such as Figure 5 and Figure 9 As shown, the interception assembly includes a filter plate 216 connected to the opening of the bucket body 209 and an interception plate 217 fixedly connected to the spiral conveying assembly 211. The interception plate 217 is perpendicular to the spiral conveying assembly 211.

[0033] The anti-blocking assembly includes a pusher plate 218 slidably connected to the interceptor plate 217, a screw 219 movably connected to the interceptor plate 217, a second motor 220 fixedly installed on the interceptor plate 217, a first gear 221 fixedly connected to the output end of the second motor 220, and a second gear 222 fixedly connected to the screw 219. The pusher plate 218 is threadedly connected to the screw 219, and the first gear 221 meshes with the second gear 222.

[0034] It should be noted that, as mentioned above, to prevent obstruction during the extrusion process, the soil or mud-stone mixture will pass through the filter plate 216 before entering the area between hopper 1 208 and hopper 2 209. Obstacles exceeding the filtration diameter of the filter plate 216 will be intercepted on the surface of the filter plate 216 and swept away from the filter plate 216 to the corresponding side area by the reciprocating sweeping action of the pusher plate 218. The movement of the pusher plate 218 is powered by the motor 220. When the motor 220 is working, it drives the gear 1 221 to rotate. When the gear 1 221 rotates, it drives the meshing gear 222 to rotate. 2. Rotation can drive the screw 219 to rotate synchronously. When the screw 219 rotates, it can drive the pusher plate 218, which is threaded to it, to move along the length of the hydraulic cylinder 210. This allows it to reciprocate along the surface of the filter plate 216. During the movement, obstacles blocking the surface of the filter plate 216 are removed from the filter plate 216, so that the standard soil or mud-stone mixture can continuously enter between the bucket body 1 208 and the bucket body 209. This allows the vehicle body 1 to maintain stable movement. Compared with the previous method of moving and transferring obstacles by bucket, this method can effectively improve the speed of the road construction process.

[0035] In an optional embodiment of the invention, such as Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, the hydraulic boom assembly includes a fixed bogie 301 fixedly mounted on the vehicle body 1, a movable bogie 302 movably connected to the fixed bogie 301, two sets of hydraulic cylinders 303 mounted on the vehicle body 1, a boom 304 movably connected to the movable bogie 302, a hydraulic cylinder 305 connected between the boom 304 and the movable bogie 302, a boom 306 movably connected to the boom 304, and a hydraulic cylinder 306 connecting the boom 304 and the boom 302. Hydraulic cylinder 6 307 between 6, hydraulic cylinder 7 309 connected between boom 3 306 and bucket 308, the output ends of two sets of hydraulic cylinder 4 303 are movably connected to the movable bogie 302, the two ends of hydraulic cylinder 5 305 are movably connected to the movable bogie 302 and boom 2 304 respectively, the two ends of hydraulic cylinder 6 307 are movably connected to boom 2 304 and boom 3 306 respectively, and the two ends of hydraulic cylinder 7 309 are movably connected to boom 3 306 and bucket 308 respectively.

[0036] It should be noted that, as mentioned above, when encountering large objects such as rocks or trees during the journey, hydraulic cylinder 303 can be used to drive the movable bogie 302 to rotate around the movable connection point with the fixed bogie 301, so that the working range of the bucket 308 can be adjusted to the position of the corresponding obstacle. Then, hydraulic cylinders 305, 307, and 309 can coordinate to adjust the posture and movement of the boom 304, boom 306, and bucket 308, so that the bucket 308 can perform crushing, shoveling, digging, and hoisting operations on the corresponding trees and rocks, thereby clearing the corresponding obstacles.

[0037] The above description of this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.

10. A bulldozing method for rapidly establishing a rescue passage, characterized in that, The bulldozing device for rapid establishment of rescue channels as described in any one of claims 1-9 includes the following steps: Step 1: The vehicle body (1) carries the continuous bulldozing mechanism (2) and the excavating mechanism (3) to the starting point of the set travel path; Step 2: Control the bottom surface of the assembled bucket assembly to fit the road surface through hydraulic boom assembly 1 and hydraulic boom assembly 2, and drive the assembled bucket assembly along the set travel path through the vehicle body (1). Step 3: Activate the extrusion assembly and the anti-blocking assembly. The extrusion assembly discharges the obstacles that have been filtered by the interception assembly into the assembled bucket assembly through the set channel to the area on the side of the travel path. The anti-blocking assembly sweeps the obstacles filtered on the interception assembly to the area on the side of the travel path. Step 4: When an obstacle with a volume exceeding the set threshold appears on the current travel path, the obstacle is broken, lifted, or excavated by the excavation mechanism (3).
