Description

Technical Field

[0001] The present application relates to the technical field of road construction, and in particular to a device for breaking the original road. Background Art

[0002] With the development of the economy, the mileage of highways in our country has been continuously reaching new highs. After long-term use, various damages will occur to some highways. In order to provide people with a good travel environment, the damaged highways need to be repaired.

[0003] Before maintenance, the damaged highway needs to be broken first. The existing breaking generally uses two breaking vehicles to break the road surface. First, a breaking vehicle is used to perform preliminary breaking on the road surface. After the first breaking vehicle finishes breaking, the second breaking vehicle is started to perform secondary breaking on the road surface.

[0004] Regarding the above related technology, the inventor believes that during breaking, it is necessary to wait for the first breaking vehicle to finish breaking the ground before starting the second breaking vehicle for breaking treatment, resulting in a low breaking efficiency. Summary of the Invention

[0005] In order to improve the road breaking efficiency, the present application provides a device for breaking the original road.

[0006] The device for breaking the original road provided by the present application adopts the following technical solutions:

[0007] A device for breaking the original road, a first breaking mechanism, the first breaking mechanism is arranged on the vehicle body, and the first breaking mechanism is used for performing preliminary breaking on the road.

[0008] A second breaking mechanism, the second breaking mechanism is arranged on the vehicle body, the second breaking mechanism is located on one side of the first breaking mechanism, and the second breaking mechanism is used for performing secondary breaking on the road.

[0009] A breaking driving mechanism, the breaking driving mechanism is installed on the vehicle body, and the breaking driving mechanism is used to drive the first breaking mechanism and the second breaking mechanism to break the road.

[0010] By adopting the above technical solutions, when it is necessary to break the road, the breaking driving mechanism is started. The breaking driving mechanism drives the first breaking mechanism and the second breaking mechanism to start simultaneously. The first breaking mechanism and the second breaking mechanism break the road simultaneously. During the movement of the vehicle body, the first breaking mechanism first performs preliminary breaking on the road, causing cracks on the road surface. As the vehicle body moves, the second breaking mechanism re-breaks at the position where the first breaking mechanism originally broke, causing the crushed stones to fall off the ground. It is not necessary to use the first breaking mechanism to finish breaking the road first and then use the second breaking mechanism for breaking, thus improving the road breaking efficiency.

[0011] Optionally, the first crushing mechanism includes a mounting frame and a crushing hammer. The mounting frame is on the vehicle body. A chute penetrating through the upper and lower sides is formed on the mounting frame, and the crushing hammer is slidably arranged on the chute.

[0012] By adopting the above technical solution, when it is necessary to drive the first crushing mechanism to crush the road surface, the crushing hammer is slid on the mounting frame. When the crushing hammer slides to the bottom end and contacts the ground, the crushing hammer can crush the ground.

[0013] The chute is formed on the mounting frame, and the chute can limit the sliding position of the crushing hammer, reducing the risk of incorrect crushing position of the crushing hammer and making the use of the crushing hammer more stable.

[0014] Optionally, the second crushing mechanism includes a connecting frame and a plurality of crushing columns. A sliding groove for the vertical sliding of the crushing columns is formed on the connecting frame.

[0015] By adopting the above technical solution, when it is necessary to drive the first crushing mechanism to crush the road surface, the crushing columns are slid on the connecting frame. When the crushing columns slide to the bottom end and contact the ground, the crushing columns can crush the ground. The plurality of crushing columns crush the ground simultaneously, improving the efficiency of ground crushing. The sliding groove on the connecting frame can limit the sliding position of the crushing columns, reducing the risk of incorrect crushing position of the crushing columns and making the use of the crushing columns more stable.

[0016] Optionally, the crushing driving mechanism includes a crushing driving member, a first towing rope and a first towing wheel. The crushing driving member is arranged between the first crushing mechanism and the second crushing mechanism. The first towing wheel is rotatably arranged on the vehicle body. The height of the first towing wheel is higher than that of the crushing hammer. The first towing rope bypasses the first towing wheel. One end of the first towing rope is connected to the output shaft of the crushing driving member, and the other end of the first towing rope is connected to the crushing hammer.

[0017] By adopting the above technical solution, when the crushing driving member is started, the output shaft of the crushing driving member pulls the first towing rope downward. Since the other end of the first towing rope is arranged on the crushing hammer and the height of the first towing wheel is higher than that of the crushing hammer, the first towing rope pulls the crushing hammer upward. At this time, the crushing hammer hovers in the air. Then, the output shaft of the crushing driving member resets and moves upward. At this time, the crushing hammer moves downward to the ground under the action of its own gravity and thus hits the ground to crush the ground.

[0018] Optionally, a second traction wheel is provided on the vehicle body. The second traction wheel is disposed between the crushing driving member and the crushing column. The height of the second traction wheel is higher than that of the crushing column. A second traction rope is provided on the output shaft of the crushing driving member. The second traction rope bypasses the second traction wheel, and one end of the second traction rope away from the crushing driving member is connected to the crushing column.

[0019] By adopting the above technical solution, by providing the second traction wheel and the second traction rope, when the crushing driving member drives the crushing hammer to move upward, under the action of the second traction wheel, the second traction rope drives the crushing column to move upward. When the output shaft of the crushing driving member resets, the crushing column moves towards the ground under the action of its own gravity, so as to hit the ground and crush the ground.

[0020] Optionally, a synchronization component is provided between adjacent crushing columns. The synchronization component includes a third traction wheel and a third traction rope. The third traction wheel is rotatably disposed between adjacent crushing columns. One end of the third traction rope is connected to one crushing column, and the other end of the third traction rope is connected to another crushing column.

[0021] By adopting the above technical solution, by providing a synchronization component between adjacent crushing columns, when one of the crushing columns hovers in the air, the other crushing column hits the ground. Multiple crushing columns do not hit the ground at the same time, so that the crushing columns reciprocally crush the ground, improving the crushing efficiency of the crushing columns.

[0022] Optionally, a guiding surface is provided at the bottom end of the crushing hammer. The guiding surface is gradually narrowed and inclined from the side wall of the crushing hammer to the bottom end of the crushing hammer.

[0023] By adopting the above technical solution, by providing the guiding surface, and the guiding surface is gradually narrowed and inclined from the side wall of the crushing hammer to the bottom end of the crushing hammer, the contact area between the bottom end of the crushing hammer and the ground is reduced, thereby increasing the impact force of the crushing hammer on the ground and improving the crushing efficiency of the crushing hammer.

[0024] Optionally, the crushing hammer includes a connecting portion and a crushing portion. The crushing portion is disposed at the bottom end of the connecting portion. A plugging portion is provided on one side of the crushing portion close to the connecting portion. The connecting portion is provided with a plugging groove for the plugging portion to be inserted. A connecting groove is provided on the groove wall of the plugging groove of the connecting portion. A fixing block is slidably disposed in the connecting groove. A locking groove opposite to the connecting groove is provided on the side wall of the plugging portion. A spring is provided between the fixing block and the bottom of the connecting groove. The spring presses the fixing block partially into the connecting groove.

[0025] By adopting the above technical solution, since the bottom end of the breaker impacts and breaks the ground for a long time, the bottom end of the breaker is prone to damage. Moreover, the breaker itself is relatively large in size, and replacement requires a large amount of cost and is not convenient for replacement. This solution sets a connecting part and a breaking part. The breaking part breaks the ground. When the breaking part is damaged, the fixing block is slid into the connecting groove. At this time, the fixing block does not limit the locking groove, and the breaking part can be detached from the connecting part. A new breaking part can be installed on the connecting part, and only the breaking part needs to be replaced, saving a large amount of cost.

[0026] Optionally, a connecting rod is provided at one end of the fixing block away from the spring. A connecting hole for the connecting rod to pass through is formed in the groove wall of the connecting groove of the connecting part, and the connecting rod penetrates to the outer side wall of the connecting part.

[0027] By adopting the above technical solution, when the breaker needs to be replaced, the connecting rod is pulled in a direction away from the locking groove. The connecting rod drives the fixing block to completely slide into the connecting groove. At this time, the fixing block does not restrict the breaking part, and the breaking part can be detached from the connecting part, facilitating the disassembly of the breaking part.

[0028] Optionally, a guard plate is provided on the vehicle body, and the guard plate surrounds the lower sides of the breaker and the breaking column.

[0029] By adopting the above technical solution, when the breaker and the breaking column break the ground, it will cause the crushed stones to fly, resulting in the crushed stones hitting passers-by and causing danger. This solution sets a guard plate to surround the lower sides of the breaker and the breaking column, reducing the risk of the crushed stones flying. On the other hand, it can reduce the risk of dust flying and polluting the environment.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. A road breaking device improves the efficiency of road breaking by setting a first breaking mechanism, a second breaking mechanism and a breaking driving mechanism, and the breaking driving mechanism can drive the first breaking mechanism and the second breaking mechanism to break the ground simultaneously.

[0032] 2. A road breaking device is convenient for the use of the first breaking mechanism and the second breaking mechanism by setting a breaking driving part, a second traction wheel and a second traction rope, and the breaking driving part can drive the first breaking mechanism and the second breaking mechanism to break the ground simultaneously.

[0033] 3. A road breaking device improves the breaking efficiency of the breaking column by setting a synchronization component to make the breaking column reciprocally break the ground. Description of the Drawings

Detailed implementation manners

[0041] The following Figure 1-6 further elaborates on this application in detail.

[0042] The embodiment of this application discloses an original road breaking device.

[0043] Referring to Figure 1 , the original road breaking device includes a vehicle body 1, a first breaking mechanism 2, a second breaking mechanism 3 and a breaking driving mechanism 4. The first breaking mechanism 2, the second breaking mechanism 3 and the breaking driving mechanism 4 are all installed on the vehicle body 1. The vehicle body 1 can drive the first breaking mechanism 2, the second breaking mechanism 3 and the breaking driving mechanism 4 to move forward along the length direction of the road. The ground can be preliminarily broken by the first breaking mechanism 2, the ground can be broken for the second time by the second breaking mechanism 3, and the first breaking mechanism 2 and the second breaking mechanism 3 can be driven by the breaking driving mechanism 4 to break the ground simultaneously, improving the breaking efficiency of the road.

[0044] Referring to Figure 2 and Figure 3 , the first crushing mechanism 2 includes a mounting frame 21 and a crushing hammer 22. The mounting frame 21 is installed at the tail of the vehicle body 1 by bolts. A chute 211 is provided on the side of the mounting frame 21 away from the vehicle body 1. The chute 211 is provided at the upper and lower ends of the mounting frame 21. Slide rails 2111 are installed on both opposite sides of the mounting frame 21 in the chute 211. The crushing hammer 22 is slidably connected between the two slide rails 2111.

[0045] Referring to Figure 4 , the crushing hammer 22 includes a connecting portion 221 and a crushing portion 222. The crushing portion is installed at the bottom of the connecting portion 221. A plugging portion 2221 is provided on one side of the crushing portion 222 close to the connecting portion 221. The plugging portion 2221 and the crushing portion 222 are integrally formed. A plugging groove 2211 for inserting the crushing portion 222 is vertically provided on one side of the connecting portion 221 close to the crushing portion 222. A fixing assembly 5 is provided between the connecting portion 221 and the crushing portion 222. The crushing portion 222 is detachably connected to the connecting portion 221 through the fixing assembly 5. When the crushing portion 222 is damaged, the crushing portion 222 can be removed and replaced, thus saving a large amount of costs.

[0046] The fixing assembly 5 includes a fixing block 51, a spring 52 and a connecting rod 53. A connecting groove 22111 is vertically provided on the side wall of the plugging groove 2211 of the connecting portion 221. The fixing block 51 is slidably inserted into the connecting groove 22111. The spring 52 is provided between the fixing block 51 and the bottom of the connecting groove 22111. The spring 52 presses a part of the fixing block 51 out of the notch of the connecting groove 22111. A locking groove 22211 opposite to the notch of the connecting groove 22111 is vertically provided on the side wall of the plugging portion 2221. The fixing block 51 is pressed into the locking groove 22211 under the extrusion of the spring 52. When a part of the fixing block 51 slides into the locking groove 22211, the fixing block 51 limits the plugging portion 2221, so that the plugging portion 2221 cannot be disengaged from the plugging groove 2211, thereby locking the crushing portion 222.

[0047] Referring to Figure 4, the connecting rod 53 is threadedly connected to one end of the fixed block 51 close to the spring 52. A connecting hole 22112 for the sliding of the connecting rod 53 is vertically opened on the groove wall of the connecting groove 22111 of the connecting portion 221. The connecting hole 22112 penetrates to the outer side wall of the connecting portion 221. The connecting rod 53 slides out to the outside through the connecting hole 22112. A connecting block 531 is coaxially arranged at one end of the connecting rod 53 away from the fixed block. The connecting block 531 abuts against the outer side wall of the connecting portion 221. The connecting portion 221 can limit the fixed block 51, so that the fixed block 51 will not completely come out of the connecting groove 22111 under the extrusion of the spring 52. On the other hand, when the breaker 22 needs to be unlocked, the connecting block 531 can be held by hand, and the connecting block 531 is moved to the side away from the connecting portion 221. The connecting block 531 drives the fixed block 51 to slide into the connecting groove 22111, and the fixed block 51 does not limit the inserting portion 2221, which facilitates the replacement of the breaking portion 222.

[0048] An inclined surface 511 is arranged on the side of the fixed block 51 away from the spring 52. The inclined surface 511 is inclined towards the inserting direction of the inserting portion 2221. When the inserting portion 2221 is inserted into the inserting groove 2211, the guiding surface 2222 abuts against the inserting portion 2221. Since the connecting groove 22111 limits the fixed block 51, the fixed block 51 can only slide into the connecting groove 22111. At this time, the fixed block 51 is extruded by the spring 52 and is in a compressed state. When the locking groove 22211 of the inserting portion 2221 slides to be opposite to the connecting groove 22111, the spring 52 presses a part of the fixed block 51 into the locking groove 22211, which does not require manual operation and facilitates the replacement of the breaking portion 222.

[0049] Preferably, in this embodiment, two sets of fixing components 5 are preferably provided. The two sets of fixing components 5 are respectively arranged on both sides of the inserting groove 2211. By providing two sets of fixing components 5, the two fixed blocks 51 can bear the weight of the breaking portion 222 at the same time, making the fixing of the breaking portion 222 more stable. And when one set of fixing components 5 is damaged, the other set of fixing components 5 can still fix the breaking portion 222.

[0050] Refer to Figure 4 , a guiding surface 2222 is arranged at one end of the breaking portion 222 away from the connecting portion 221. The guiding surface 2222 is gradually narrowed and inclined from the outer peripheral wall of the breaking portion 222 to the bottom wall of the breaking portion 222. By providing the guiding surface 2222, and the guiding surface 2222 is gradually narrowed and inclined from the side wall of the breaker 22 to the bottom end of the breaker 22, the contact area between the bottom end of the breaker 22 and the ground is reduced, thereby increasing the impact force of the breaker 22 on the ground and improving the breaking efficiency of the breaker 22.

[0051] Refer to Figure 2 and Figure 5, the second crushing mechanism 3 includes a connecting frame 31 and crushing columns 32. The connecting frame 31 is installed on the side of the mounting frame 21 away from the vehicle head by bolts. On the side of the connecting frame 31 away from the vehicle body 1, three sliding grooves 311 are vertically opened, and the sliding grooves 311 penetrate to the end of the connecting frame 31 close to the vehicle body 1. There are three crushing columns 32, and the three crushing columns 32 are slidably inserted into their respective corresponding sliding grooves 311. The crushing column 32 in the middle weighs more than the other two crushing columns 32.

[0052] Refer to Figure 2 , the crushing driving mechanism 4 includes a crushing driving member 41, a first traction wheel 42, a first traction rope 43, a second traction wheel 44 and a second traction rope 45. A placing frame 6 is provided between the mounting frame 21 and the connecting frame 31 by bolts. A placing groove 61 is opened on the placing frame 6, and the crushing driving member 41 is installed in the placing groove 61 by bolts. The crushing driving member 41 is located between the mounting frame 21 and the connecting frame 31. In this embodiment, the crushing driving member 41 is preferably set as an oil cylinder.

[0053] The first traction wheel 42 is rotatably installed on the mounting frame 21 through a rotating shaft. The first traction wheel 42 is located above the connecting portion 221. The first traction rope 43 bypasses the first traction wheel 42. One end of the first traction rope 43 is connected to the crushing driving member 41, and the other end of the first traction rope 43 is connected to the connecting portion 221. When the output shaft of the crushing driving member 41 slides downward, the output shaft of the crushing driving member 41 drives the first traction rope 43 to move downward. Since the first traction wheel 42 is located above the connecting portion 221, the first traction rope 43 drives the connecting portion 221 to move upward. At this time, the connecting portion 221 is in a suspended state. When the output shaft of the crushing driving member 41 resets and slides upward, under the influence of its own gravity, the connecting portion 221 automatically falls downward, so as to fall to the ground and crush the ground.

[0054] Refer to Figure 2 , the second traction wheel 44 is rotatably installed on the connecting frame 31 through a rotating shaft. The second traction wheel 44 is located above the crushing column 32. The second traction rope 45 bypasses the second traction wheel 44. One end of the second traction rope 45 is connected to the crushing driving member 41, and the other end of the first traction rope 43 is connected to one of the crushing columns 32 in the middle. When the output shaft of the crushing driving member 41 slides downward, the output shaft of the crushing driving member 41 drives the second traction rope 45 to move downward. Since the second traction wheel 44 is located above the crushing column 32, the second traction rope 45 drives the crushing column 32 to move upward. At this time, the crushing column 32 is in a suspended state. When the output shaft of the crushing driving member 41 resets and slides upward, under the influence of its own gravity, the crushing column 32 automatically falls downward, so as to fall to the ground and crush the ground.

[0055] The crushing driving member 41 can drive the crushing hammer 22 and the crushing column 32 to operate simultaneously, facilitating the operation of the crushing hammer 22 and the crushing column 32. When the vehicle body 1 moves, the crushing hammer 22 first crushes the ground. After the crushing is completed, the vehicle body 1 continues to move. At this time, the crushing column 32 is located at the position where the ground was crushed by the crushing hammer 22 before, and the crushing column 32 performs secondary crushing on the ground that has been crushed before, facilitating the crushing of the ground.

[0056] Referring to Figure 2 , it further includes a synchronization component 7. There are multiple groups of synchronization components 7, and the synchronization components 7 are arranged between adjacent crushing columns 32. The synchronization component 7 includes a third traction wheel 71 and a third traction rope 72. The third traction wheel 71 is rotatably connected to the connecting frame 31 through a rotating shaft. The third traction rope 72 bypasses the third traction wheel 71. One end of the third traction wheel 71 is connected to one crushing column 32, and the other end of the third traction wheel 71 is connected to another crushing column 32.

[0057] When one of the middle crushing columns 32 hovers in mid-air, the other two crushing columns 32 fall to the ground. The three crushing columns 32 do not fall to the ground simultaneously, enabling the crushing columns 32 to reciprocally crush the ground, improving the crushing efficiency of the crushing columns 32.

[0058] Referring to Figure 6 , a surrounding plate 8 is provided at the bottom of the mounting frame 21, the connecting frame 31, and the placement frame 6 through bolts. The surrounding plate 8 surrounds the lower sides of the crushing hammer 22 and the crushing column 32. When the crushing hammer 22 and the crushing column 32 crush the ground and cause the crushed stones to fly, the surrounding plate 8 shields the crushed stones, reducing the risk of the crushed stones flying. On the other hand, it can reduce the risk of dust flying and polluting the environment.

[0059] The implementation principle of an original road crushing device in an embodiment of the present application is as follows: When the road needs to be crushed, the crushing driving member 41 is started, and the output shaft of the crushing driving member 41 retracts, thereby pulling the crushing hammer 22 and a crushing column 32 upward. At this time, the crushing hammer 22 and a crushing column 32 are in a suspended state, and the two crushing columns 32 on both sides fall to the ground to crush the ground. The output shaft of the crushing driving member 41 moves upward, and the crushing hammer 22 and the crushing column 32 naturally fall to the ground under the influence of gravity to crush the ground. At this time, the other two crushing columns 32 are lifted into a suspended state, and this process is repeated to crush the ground, improving the crushing efficiency of the ground.

[0060] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. 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.
