Description

Technical Field

[0001] This invention relates to the field of vehicle floor technology, specifically to a vehicle floor structure that facilitates automatic unloading. Background Technology

[0002] Dump trucks are widely used in mining, large and medium-sized civil engineering projects, and national infrastructure construction, and have become the mainstay of engineering vehicles. The structure of a dump truck includes a main frame, a subframe, and a dump body. The subframe is mounted on the main frame to reduce the impact on the main frame when the dump body falls back onto it after unloading. The rear end of the dump body's floor structure is rotatably mounted on the rear end of the subframe.

[0003] Traditional dump trucks are commonly rear-tipping or side-tipping models. When transporting bulk goods (such as construction waste and industrial waste), the uneven particle size of the material loaded inside the truck bed can easily create a "bridging effect" under gravity, hindering the overall flow and making it difficult to unload and discharge the material. At the same time, if the vehicle's hydraulic system experiences insufficient pressure or electrical failure, the cargo box is prone to accidental falling, posing a significant danger. To address these issues, we propose a vehicle floor structure that facilitates automatic unloading. Summary of the Invention

The coordinated design of the cylindrical block and the anti-detachment block ensures stability and safety during the striking process.

[0020] 3. The coordinated operation of the transmission mechanism and the ratchet assembly enables automated control and safety protection of the unloading process. When the telescopic rod slides in the transmission cavity, the locking and releasing of the ratchet assembly can be precisely controlled by the switching component and the insertion and cooperation of the left top block and the right top rod, thereby preventing the cargo box from falling accidentally during unloading and ensuring the safety of the operators.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Both ends of the hinge shaft 5 are fixedly connected to ratchet assembly 15. The ratchet assembly 15 is movably disposed in the transmission cavity 10. The transmission cavity 10 is hollow and disposed in the main frame 1. The ratchet assembly 15 is fixedly connected to one end of the telescopic rod 13. The telescopic rod 13 is slidably sleeved on the guide seat 12. The guide seat 12 is fixedly installed in the transmission cavity 10. The other end of the telescopic rod 13 is fixedly connected to the transmission mechanism 11. A spring 14 is provided between the guide seat 12 and the transmission mechanism 11. The spring 14 is movably sleeved on the outside of the telescopic rod 13.

[0035] Example 2

[0036] Reference Figure 1-8 This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, the lifting assembly 6 includes a support shaft 61, a mounting base 62, a hydraulic cylinder 63, a transmission base 64, and a transmission shaft 65. The two ends of the support shaft 61 are rotatably connected to the two side walls of the main frame 1, the middle part of the support shaft 61 is fixedly connected to the mounting base 62, one end of the mounting base 62 is fixedly connected to one end of the hydraulic cylinder 63, the other end of the hydraulic cylinder 63 is fixedly connected to the transmission base 64, the transmission base 64 is hinged to the middle part of the transmission shaft 65, and the two ends of the transmission shaft 65 are fixedly connected to the two side walls of the tilting frame 2.

[0037] Furthermore, the drive shaft 65 is located between the rotating shaft 8 and the hinge shaft 5, and the support shaft 61 is located on the side away from the hinge shaft 5.

[0038] The lifting assembly 6 drives the tilting frame 2 to achieve the automatic tilting and unloading function of the bottom plate. When the hydraulic cylinder 63 is started, the linkage between the transmission seat 64 and the transmission shaft 65 can smoothly push the tilting frame 2 to rotate around the hinge shaft 5, thereby tilting the bottom plate 3 and realizing the automatic and smooth discharge of materials.

[0039] Specifically, the striking components 9 are evenly distributed along the length of the rotating shaft 8. The striking components 9 include a cam 91, a groove 92, a spring 93, an anti-detachment block 94, and a cylindrical block 95. One side of the cam 91 is fixedly connected to the rotating shaft 8, and the other side of the cam 91 has a groove 92. One end of the spring 93 is fixedly connected to the inner wall of one end of the groove 92, and the other end of the spring 93 is fixedly connected to one end of the anti-detachment block 94. The anti-detachment block 94 is slidably sleeved in the groove 92, and the other end of the anti-detachment block 94 is fixedly connected to the cylindrical block 95.

[0040] Furthermore, the cylindrical block 95 is slidably fitted into the opening of the groove 92, the outer diameter of the cylindrical block 95 is smaller than the outer diameter of the anti-detachment block 94, and the extension length of the cylindrical block 95 is greater than the shortest distance between the outer surface of the cam 91 and the outer wall of the base plate 3.

[0041] The striking component 9 is designed to drive the rotating shaft 8 to rotate via the dual output shaft motor 7, which in turn causes the cylindrical block 95 on the cam 91 to periodically strike the base plate. This effectively solves the problem of unloading difficulties caused by the "bridging effect" when transporting bulk goods in traditional dump trucks. It effectively breaks the bridging structure between materials, promotes the flow of materials, and further improves unloading efficiency. The cooperative design of the cylindrical block 95 and the anti-detachment block 94 ensures stability and safety during the striking process and prevents the cylindrical block 95 from falling off.

[0042] Specifically, the transmission mechanism 11 includes a drive gear 111, a switching component 112, a rack 113, a right push rod 114, and a left push block 115. The drive gear 111 is fixedly sleeved on both ends of the support shaft 61. The bottom of the drive gear 111 is meshed with the rack 113. The rack 113 is slidably disposed in the switching component 112. One end of the switching component 112 is fixedly connected to one end of the telescopic rod 13.

[0043] Furthermore, a left top block 115 is fixedly connected to the inner wall of the bottom of the transmission cavity 10 away from the hinge shaft 5, a right top rod 114 is fixedly connected to the inner wall of the bottom of the guide seat 12 away from the hinge shaft 5, and a limiting ring 131 is fixedly sleeved on the side of the telescopic rod 13 away from the switching component 112. One end of the limiting ring 131 is fixedly connected to one end of the second spring 132, and the other end of the second spring 132 is fixedly connected to the ratchet assembly 15. The second spring 132 is movably sleeved outside the telescopic end of the telescopic rod 13.

[0044] After unloading is completed, the piston rod of the hydraulic cylinder 63 extends a certain distance, causing the support shaft 61 to rotate counterclockwise by a certain angle. The support shaft 61 drives the fixed drive gear 111 to rotate, and the drive gear 111 drives the meshing rack 113 to move. The rack 113 then drives the movable housing 1121 of the switching assembly 112 to move towards the right push rod 114. The right push rod 114 is inserted into the movable housing 1121 through the right port 1126. The top of the right push rod 114 abuts against the bottom side of the movable rod 1127, through a lever. The principle is that the locking block 1120 fixed to the movable rod 1127 disengages from the locking block 1123 on one side. Under the elastic force of the return spring 1124, the rack 113 retracts into the movable housing 1121, thereby disengaging the rack 113 from the engagement of the drive gear 111 and disengaging the rack 113 from the limit position. Then, under the elastic force of the spring 14, the movable housing 1121 moves towards the left top block 115, and at the same time, the fixed telescopic rod 13 moves to the left. The telescopic rod 13 causes the pawl 151 fixed at the end to disengage from the engagement of the ratchet 152.

[0045] Furthermore, the switching assembly 112 includes a movable housing 1121, a guide groove 1122, a locking block 1123, a return spring 1124, a left port 1125, a right port 1126, a movable rod 1127, a clamping spring 1128, a cylindrical pin 1129, and a locking block 1120. The movable housing 1121 is slidably disposed within the transmission cavity 10. The inner walls on both sides of the movable housing 1121 are respectively provided with recessed guide grooves 1122, which slidably engage with the outer walls on both sides of the rack 113. The bottom ends of both ends of the rack 113 are respectively fixedly connected to the locking blocks 1123, which are movably disposed within the movable housing 1121. Furthermore, the top of the snap-fit ​​block 1123 is fixedly connected to one end of the return spring 1124, and the other end of the return spring 1124 is fixedly connected to the top inner wall of the movable housing 1121. One side of the snap-fit ​​block 1123 is snap-fitted with a snap-fit ​​block 1120. The end of the snap-fit ​​block 1120 away from the snap-fit ​​block 1123 is fixedly connected to the movable rod 1127. The top of the movable rod 1127 is rotatably sleeved with a cylindrical pin 1129. The cylindrical pin 1129 is fixedly installed inside the movable housing 1121. One end of the top of the movable rod 1127 is fixedly connected to one end of the clamping spring 1128, and the other end of the clamping spring 1128 is fixedly connected to the inner wall of one side of the movable housing 1121.

[0046] Furthermore, a left through-hole 1125 is provided through the bottom of one end of the movable housing 1121, and the left through-hole 1125 is inserted into the left top block 115. A right through-hole 1126 is provided through the bottom of the other end of the movable housing 1121, and the right through-hole 1126 is inserted into the right top rod 114. The left top block 115 has a right trapezoidal structure.

[0047] Specifically, the ratchet assembly 15 includes a pawl 151 and a ratchet 152. The ratchet 152 is fixedly sleeved on both ends of the hinge shaft 5. One side of the ratchet 152 is engaged with the pawl 151. The pawl 151 is fixedly connected to the end of the telescopic rod 13.

[0048] Hydraulic cylinder 63 retracts, causing the tilting frame 2 to rotate in the opposite direction around the hinge shaft 5, and the base plate 3 gradually returns to a horizontal state. During the reverse rotation of the tilting frame 2, the left top block 115 is inserted into the left passage 1125. The inclined surface of the left top block 115 abuts against the bottom wall of the locking block 1123 and the rack 113, causing the rack 113 to gradually rise. After the top surface of the left top block 115 and the bottom surface of the rack 113 slide into contact, the locking block 1120 re-engages with the bottom wall of the locking block 1123, keeping the position of the rack 113 fixed, which facilitates subsequent re-meshing with the drive gear 111. At the same time, when the drive gear 111 rotates clockwise, it can still drive the rack 113 to move to the left. And when the base plate 3 gradually returns to a horizontal state, the ratchet 152 and the pawl 151 are always in a disengaged state.

[0049] The working principle and process are as follows: A carriage is fixedly welded onto the base plate 3. When unloading is required, the hydraulic cylinder 63 of the lifting assembly 6 operates, and the piston rod of the hydraulic cylinder 63 extends, pushing the transmission seat 64 to move. The transmission seat 64 and the transmission shaft 65 are hinged. Since the two ends of the transmission shaft 65 are respectively fixedly connected to the two side walls of the tilting frame 2, the tilting frame 2 is driven to rotate around the hinge shaft 5, and the base plate 3 tilts accordingly, realizing automatic unloading of materials. During the rotation of the tilting frame 2 around the hinge shaft 5, the ratchet 152 at both ends of the hinge shaft 5 rotates accordingly. At the same time, the support shaft 61 is fixedly connected to the mounting seat 62. When the hydraulic cylinder 63 extends and operates... The support shaft 61 rotates counterclockwise, which in turn drives the fixed drive gear 111 to rotate. The drive gear 111 drives the meshing rack 113 to move. The rack 113 drives the movable housing 112 to move toward the ratchet assembly 15. Under the action of the elastic force of the telescopic rod 13 and the linear movement of the telescopic rod 13, the pawl 151, which was in a disengaged state, engages with the ratchet 152. Under the action of the elastic force of the spring 132, the pawl 151 always engages with the ratchet 152, ensuring that the ratchet assembly 15 is in a locked state, preventing the cargo box from falling accidentally during unloading and ensuring operational safety.Simultaneously, the dual-output shaft motor 7 starts, driving the rotating shaft 8 to rotate. The cam 91 on the rotating shaft 8 rotates accordingly. When the cylindrical block 95 on the cam 91 rotates to contact the outer wall of the base plate 3, the cylindrical block 95 strikes the base plate 3 under the push of the cam 91. When the cylindrical block 95 on the cam 91 rotates away from the outer wall of the base plate 3, it stops striking the base plate 3. This repeated striking work effectively breaks the bridging structure between materials, promotes material flow, and improves unloading efficiency. After unloading is completed, the piston rod of the hydraulic cylinder 63 extends a certain distance, driving the support shaft 61 to rotate counterclockwise again. When the support shaft 61 moves by a certain angle, it drives the fixed drive gear 111 to rotate. The drive gear 111 drives the meshing rack 113 to move. The rack 113 then drives the movable housing 1121 of the switching assembly 112 to move towards the right push rod 114. The right push rod 114 is inserted into the movable housing 1121 through the right port 1126. The top of the right push rod 114 abuts against the bottom side of the movable rod 1127. Through the lever principle, the locking block 1120 fixed to the movable rod 1127 disengages from the locking block 1123 on one side. Under the elastic force of the return spring 1124, the rack... 113 retracts into the movable housing 1121, thereby disengaging the rack 113 from the drive gear 111 and releasing the rack 113 from its limit position. Then, under the elastic force of the spring 3 14, the movable housing 1121 moves towards the left top block 115, simultaneously moving the fixed telescopic rod 13 to the left. The telescopic rod 13 causes the pawl 151 fixed at its end to disengage from the ratchet 152. Then, the hydraulic cylinder 63 retracts, causing the tilting frame 2 to rotate in the opposite direction around the hinge axis 5, and the base plate 3 gradually returns to a horizontal state. During the reverse rotation of the tilting frame 2, the left top block 115 inserts into the left passage. Inside the opening 1125, the inclined surface of the left top block 115 abuts against the bottom wall of the locking block 1123 and the rack 113, causing the rack 113 to gradually rise. After the top surface of the left top block 115 and the bottom surface of the rack 113 slide into contact, the locking block 1120 re-engages with the bottom wall of the locking block 1123, keeping the rack 113 in a fixed position for easy re-engagement with the drive gear 111. Simultaneously, when the drive gear 111 rotates clockwise, it can still drive the rack 113 to move to the left. Furthermore, as the base plate 3 gradually returns to a horizontal state, the ratchet 152 and the pawl 151 remain disengaged.
