Description

Technical Field

[0001] The invention relates to the technical field of road construction compaction equipment, in particular to highway roadbed compaction equipment and a working method used for road construction. Background Art

[0002] During the road construction process, it is necessary to lay the roadbed on the ground. The roadbed needs to be compacted. The compaction device is used to move back and forth, and the roadbed soil is deformed under pressure under the compaction of heavy objects, so as to compact and strengthen the roadbed, ensure the bearing capacity and stability of the road, and prevent potholes and bumps on the road surface. In the process of roadbed compaction, uniform speed movement is usually adopted to ensure that each roadbed position is compacted with the same pressure and for the same time, so that the compaction degree of each part of the roadbed is consistent.

[0003] However, the prior art uses a plum blossom-shaped compacting device to impact the roadbed. The outer side of the plum blossom-shaped compacting device is irregular, and the rotation of the plum blossom-shaped compacting device will form a hollow position with the roadbed. During rotation, a portion of the roadbed cannot be compacted. The roadbed of the roller compacting device can be compacted, but the roller uses gravity for compaction, and its impact force is insufficient. Due to these two problems, during the compaction process, it cannot be guaranteed that the roadbed is punched at a certain frequency without omissions in the moving distance, which affects the uniformity of the roadbed compaction. Summary of the invention

[0004] The present invention provides a highway roadbed compaction equipment and a working method for road construction, which overcomes the shortcomings described in the background technology.

[0005] The technical solution adopted by the present invention to solve its technical problem is: A highway roadbed compaction equipment for road construction, comprising a rolling mechanism, a compaction vehicle, a baffle, a roller, and a head, wherein the roller is arranged at the lower end of the compaction vehicle, and the compaction vehicle and the head are connected in an integrated manner, a seat is arranged at the upper end of the compaction vehicle, both sides of the rolling mechanism are arranged at the lower end of the head, and the baffle is engaged with the lower end of the head, and there is a gap between the baffle and the outer side of the rolling mechanism, the roller is controlled to rotate and move on the seat of the compaction vehicle, and the roller and the rolling mechanism are moved on the roadbed under the gravity of the head, so as to push the rolling mechanism to compact the roadbed under its own gravity; The rolling mechanism is provided with an arc plate, a rolling structure, a spring, a connecting shaft, and a supporting mechanism. Two supporting mechanisms are provided, which are fixed at the lower end of the vehicle head and symmetrically arranged at the outer end of the connecting shaft. Six spring annular arrays are distributed on the outside of the connecting shaft. The spring is arranged and connected to the inner side of the rolling structure, and the connecting shaft is driven to rotate by the spring, so that the rolling structure elastically rotates around the connecting shaft. The connecting shaft passes through the middle rolling structure, and the outer ends of the left and right sides of the connecting shaft are arranged in the supporting mechanism. When the outer side of the rolling structure rolls on the roadbed surface, the rolling structure will rotate and be blocked by the arc plate fixed on the outer side of the connecting shaft, so that the rolling structure exerts a punching force on the roadbed under the resistance of the arc plate.

[0006] A better technical solution: the connecting shaft is provided with a bearing ring and a metal rod, and the spring is arranged on the outside of the bearing ring. When the rolling structure rotates, the connected spring is driven to rotate, and the bearing ring is driven to rotate outside the metal rod through the spring. The metal rod passes through the middle of the rolling structure, and the left and right outer ends of the metal rod are fixedly arranged in the middle of the supporting mechanism. The arc plate is arranged at the lower right end of the metal rod, and is squeezed and matched with the arc plate when the rolling structure rotates.

[0007] A better technical solution: the rolling structure is provided with a rubber ring, a rolling tube, a force-bearing structure, and a gravity block. The metal rod penetrates and rotates inside the gravity block. The rubber ring is arranged on the outside of the gravity block and fits on the inner side of the middle of the rolling tube. The force-bearing structure is arranged on the left and right sides of the rolling tube. When the rolling tube moves on the roadbed, the six force-bearing structures rotate and extrude the arc plate at the outer end of the metal rod. After being blocked by the arc plate, the force-bearing structure reversely extrude the roadbed surface.

[0008] A better technical solution: the load-bearing structure is provided with a load-bearing plate, a rolling strip, and a load-bearing rod. The load-bearing plate is arranged on the inner side of the rolling strip, and the load-bearing rod is fixed in the middle position of the load-bearing plate. When the load-bearing rod is blocked by the arc plate, the load-bearing plate is elastically bent toward the gap between the rolling strips, and the load-bearing rod is pressed against the roadbed. When the load-bearing structure rotates, the six load-bearing rods intermittently press against the roadbed during rotation.

[0009] A better technical solution: the force-bearing rods are arranged on the left and right sides of the rolling tube and distributed in a circular array, and the outer end of the spring is arranged on the inner side of the rolling strip. When the rolling strip rolls on the roadbed, the rolling generated by the movement of the rolling strip drives the spring to rotate outside the connecting shaft, and when the rolling is blocked, the force-bearing rods are squeezed out from the gap between the rolling strips and impact the roadbed.

[0010] A better technical solution: the support mechanism is provided with a connecting plate, a guide plate, a limiting hole, a metal sheet, and a rubber block. The outer end of the connecting shaft is fixedly arranged in the connecting plate inside the connecting plate, the rubber block is arranged between the connecting plate and the guide plate, and the metal sheet is arranged between the guide plate and the connecting plate. The roller moves and causes the front of the vehicle to push the connecting shaft in the middle of the limiting hole to be compacted on the roadbed.

[0011] A better technical solution: the metal sheet and the connecting plate are inclined at 40 degrees. When the connecting plate drives the connecting shaft to compact the roadbed, the resistance of the roadbed to the connecting shaft acts in the opposite direction to the connecting plate, and squeezes the connecting plate toward the guide plate connected to the metal sheet.

[0012] A preferred technical solution: the guide plate is provided with a movable plate, a support plate, a rubber plate, and a hinge rod. The hinge rod is arranged on the side of the lower end of the support plate. When the connecting plate moves upward, it is blocked by the rubber block and causes the connecting plate to squeeze the movable plate at the position of the metal sheet. After being squeezed by the connecting plate, the movable plate rotates counterclockwise around the hinge rod as the center and supports the connecting plate under the elasticity of the rubber plate.

[0013] Working methods of highway subgrade compaction equipment used in road construction: S1: First, the roller is controlled to move at the compacting vehicle position, so that the rolling mechanism connected to the lower end of the vehicle head and the roller move horizontally, and the roadbed is compacted under the weight of the rolling mechanism itself.

[0014] S2: When the rolling mechanism contacts the roadbed for compaction, the rolling structure rolls clockwise under the gravity of the gravity block and rolls the roadbed, wherein when the rolling structure rolls, the force-bearing rods in the force-bearing structure rotate along with the rolling under the connection with the rolling strips.

[0015] S3: After the load-bearing rod rotates, it reaches the outer side of the arc plate and is blocked by the arc plate during rotation. Since the arc plate is fixed by a metal rod, it blocks the load-bearing rod from driving the load-bearing plate to squeeze out from the gap between the rolling strips. At this time, the six load-bearing structures block the load-bearing structures at the arc plate position while rolling and strengthen the downward impact force on the roadbed.

[0016] S4: The load-bearing structure is connected by springs when intermittently punching the roadbed, and rotates with the point of the bearing ring on the outside of the metal rod as the support point, so that the load-bearing structure rolls while driving the rolling tube to rotate, and the roadbed is rolled by the gravity of the gravity block. In this process, the gravity block elastically squeezes the rubber ring and drives the metal rod and the bearing ring to jump intermittently, and drives the force of the load-bearing structure on the roadbed to perform intermittent impacts through the connection of the spring.

[0017] S5: Secondly, when the roadbed is stamped between the load-bearing structures, the metal rod connected at the center is fixed at the position of the limiting hole in the connecting plate. The fluctuation caused by the stamping of the roadbed causes the connecting plate to squeeze the metal sheet upward, and the movable plate drives the connecting plate to rotate upward with the hinge rod as the center. At the same time, the elasticity of the rubber plate causes the movable plate to generate a downward rotation force, and the downward rotation force of the movable plate forms an elastic downward pressing at the inclined position above the connecting plate.

[0018] Compared with the prior art, this technical solution has the following advantages: In the present invention, the roller is controlled to rotate and push the rolling mechanism to move when the compacting vehicle is in position, wherein the baffle plate can block and clean the road foundation stone rolled up by the rolling mechanism, and then when the rolling structure compacts the road surface, the rolling structure rotates counterclockwise, so that the rolling structure rotates around the bearing ring under the elastic connection of the spring, and is blocked by the arc plate fixed on the outside of the metal rod during rotation. At this time, the front of the vehicle supports the rolling mechanism at the lower end, so the six force-bearing structures of the rolling structure are pressed by the arc plate in turn under the rotation and the downward punching force is enhanced. Under the moving rotation, the rolling structure and the arc plate are blocked and coordinated, so that the present invention has the interval impact effect of the plum blossom-shaped compacting device, and the circular rolling structure prevents the plum blossom-shaped compacting device from generating a hollow position, thereby achieving the effect of increasing the continuous punching in the process of stable compaction of the roadbed.

[0019] The rubber plate in the present invention generates elastic force downward to support the upward blocking force of the connecting plate, and forms lateral elastic support, so that the metal rod has a lateral elastic effect, which can buffer the uneven roadbed when the resistance is too large. In addition, the support mechanism in the present invention can also block the intermittent movement of the rolling structure to a certain extent, thereby enhancing the elastic rolling effect of the rolling structure when rolling under elasticity.

[0031] like Figures 1 to 6 As shown, the present invention proposes a highway roadbed compaction equipment for road construction, including a rolling mechanism 1, a compaction vehicle 2, a baffle 3, a roller 4, and a head 5, wherein the roller 4 is arranged at the lower end of the compaction vehicle 2, and the compaction vehicle 2 and the head 5 are integrally connected, a seat is arranged at the upper end of the compaction vehicle 2, both sides of the rolling mechanism 1 are arranged at the lower end of the head 5, and the baffle 3 is engaged at the lower end of the head 5, and there is a gap between the baffle 3 and the outer side of the rolling mechanism 1, the roller 4 is controlled to rotate and move on the seat of the compaction vehicle 2, and the roller 4 and the rolling mechanism 1 are moved on the roadbed under the gravity of the head 5, so as to push the rolling mechanism 1 to compact the roadbed under its own gravity; The rolling mechanism 1 is provided with an arc plate 11, a rolling structure 12, a spring 13, a connecting shaft 14, and a supporting mechanism 15. Two supporting mechanisms 15 are provided and are fixed to the lower end of the vehicle head 5 and symmetrically arranged at the outer end of the connecting shaft 14. Six springs 13 are distributed in a circular array on the outer side of the connecting shaft 14. The spring 13 is arranged and connected to the inner side of the rolling structure 12, and the connecting shaft 14 is driven to rotate by the spring 13, so that the rolling structure 12 elastically rotates around the connecting shaft 14. The connecting shaft 14 passes through the middle rolling structure 12, and the outer ends of the left and right sides of the connecting shaft 14 are arranged in the supporting mechanism 15. When the outer side of the rolling structure 12 rolls on the roadbed surface, the rolling structure 12 will rotate and be blocked by the arc plate 11 fixed to the outer side of the connecting shaft 14, so that the rolling structure 12 exerts a punching force on the roadbed under the resistance of the arc plate 11.

[0032] Among them, the connecting shaft 14 is provided with a bearing ring 141 and a metal rod 142, and the spring 13 is arranged on the outside of the bearing ring 141. When the rolling structure 12 rotates, the connected spring 13 is driven to rotate, and the bearing ring 141 is driven to rotate outside the metal rod 142 through the spring 13. The metal rod 142 passes through the middle of the rolling structure 12, and the left and right outer ends of the metal rod 142 are fixedly arranged in the middle of the supporting mechanism 15. The arc plate 11 is arranged at the lower right end of the metal rod 142, and is squeezed and matched with the arc plate 11 when the rolling structure 12 rotates.

[0033] Among them, the rolling structure 12 is provided with a rubber ring 121, a rolling tube 122, a force-bearing structure 123, and a gravity block 124. The metal rod 142 penetrates and rotates inside the gravity block 124. The rubber ring 121 is arranged on the outside of the gravity block 124 and fits on the middle inner side of the rolling tube 122. The force-bearing structure 123 is arranged on the left and right sides of the rolling tube 122. When the rolling tube 122 moves on the roadbed, the six force-bearing structures 123 rotate to extrude the arc plate 11 at the outer end of the metal rod 142. After being blocked by the arc plate 11, the force-bearing structure 123 reversely extrude the roadbed surface.

[0034] In the present invention, the roller 4 is controlled to rotate and push the rolling mechanism 1 to move at the position of the compacting vehicle 2, wherein the baffle plate 3 can block and clean the road foundation stone rolled up by the rolling mechanism 1, and then when the rolling structure 12 compacts the road surface, the rolling structure 12 rotates counterclockwise, so that the rolling structure 12 rotates around the bearing ring 141 as the center under the elastic connection of the spring 13, and is blocked by the arc plate 11 fixed on the outside of the metal rod 142 during the rotation. At this time, the head 5 supports the rolling mechanism 1 at the lower end, so that the rolling structure 12 is driven by the rotation. The six force-bearing structures 123 are sequentially supported by the arc plate 11 presses against and enhances the downward punching force, and at the same time drives the rolling tube 122 to squeeze the rubber ring 121, so as to form a compression space for the gravity block 124 in the rolling tube 122, and the blocking force of the arc plate 11 on the force-bearing structure 123 is transmitted to the gravity block 124 through the metal rod 142, so as to realize the change of the load-bearing capacity of the gravity block 124. The change of the load-bearing capacity causes the downward pressure to change, and then the gravity block 124 follows the rotation of the force-bearing structure 123 to change the downward rolling force, so as to realize the effect of uniformly enhancing the punching pressure and prevent the poor effect of direct gravity rolling.

[0035] When the force-bearing structure 123 in the present invention begins to contact the arc plate 11, the position of the force-bearing structure 123 begins to contact the roadbed, and the rolling structure 12 cooperates with the arc plate 11 during movement and rotation, so that the present invention has the interval impact effect of the plum blossom-shaped compacting device, and the circular rolling structure 12 prevents the plum blossom-shaped compacting device from generating a hollow position, thereby achieving the effect of increasing continuous stamping in the process of stable compaction of the roadbed.

[0036] Among them, the load-bearing structure 123 is provided with a load-bearing plate 1231, a rolling strip 1232, and a load-bearing rod 1233. The load-bearing plate 1231 is arranged on the inner side of the rolling strip 1232, and the load-bearing rod 1233 is fixed in the middle position of the load-bearing plate 1231. When the load-bearing rod 1233 is blocked by the arc plate 11, the load-bearing plate 1231 is elastically bent toward the gap between the rolling strips 1232, and the load-bearing rod 1233 is pressed against the roadbed. Under the rotation of the load-bearing structure 123, the six load-bearing rods 1233 intermittently press against the roadbed during rotation.

[0037] In addition, the force-bearing rod 1233 is arranged on the left and right sides of the rolling tube 122 and distributed in a circular array. The outer end of the spring 13 is arranged on the inner side of the rolling strip 1232. When the rolling strip 1232 rolls on the roadbed, the rolling generated by the movement of the rolling strip 1232 drives the spring 13 to rotate outside the connecting shaft 14, and after the rolling is blocked, the force-bearing rod 1233 is squeezed out from the gap between the rolling strips 1232 and impacts the roadbed.

[0038] In the present invention, the position where the load-bearing structure 123 is blocked by the curved plate 11 when rotating is outside the load-bearing rod 1233. After being blocked by the curved plate 11, the load-bearing plate 1231 is driven to bend outward and squeezed out from the gap between the rolling strips 1232 to act on the roadbed surface. Under the continuous rotation of the load-bearing structure 123, the six load-bearing structures 123 are in intermittent contact with the fixed curved plate 11, thereby realizing a continuous change in the impact pressure on the roadbed.

[0039] Among them, the supporting mechanism 15 is provided with a connecting plate 151, a guide plate 152, a limiting hole 153, a metal sheet 154, and a rubber block 155. The outer end of the connecting shaft 14 is fixedly arranged in the connecting plate 151 inside the connecting plate 151. The rubber block 155 is arranged between the connecting plate 151 and the guide plate 152. The metal sheet 154 is arranged between the guide plate 152 and the connecting plate 151. The roller 4 moves and enables the front of the vehicle 5 to push the connecting shaft 14 in the middle of the limiting hole 153 to be compacted on the roadbed.

[0040] In addition, the metal sheet 154 and the connecting plate 151 are inclined at 40°. When the connecting plate 151 drives the connecting shaft 14 to compact the roadbed, the resistance of the roadbed to the connecting shaft 14 acts in the opposite direction to the connecting plate 151, and causes the connecting plate 151 to be squeezed toward the guide plate 152 connected to the metal sheet 154.

[0041] Among them, the guide plate 152 is provided with a movable plate 1521, a support plate 1522, a rubber plate 1523, and a hinge rod 1524. The hinge rod 1524 is arranged on the lower end side of the support plate 1522. When the connecting plate 151 moves upward, it is blocked by the rubber block 155 and causes the connecting plate 151 to squeeze the movable plate 1521 at the position of the metal sheet 154. After being squeezed by the connecting plate 151, the movable plate 1521 rotates counterclockwise around the hinge rod 1524 as the center, and supports the connecting plate 151 under the elasticity of the rubber plate 1523.

[0042] The position of the limiting hole 153 in the connecting plate 151 of the present invention is fixed to the outer end of the metal rod 142, and the guide plate 152 vertically supports the connecting plate 151 through the metal sheet 154. When the rolling structure 12 rolls over an uneven roadbed, its resistance is relatively large and is transmitted to the connecting plate 151 through the metal rod 142. Then, under the elastic support of the rubber block 155, the upper right end of the connecting plate 151 presses the guide plate 152 upward and drives the movable plate 1521 to rotate with the hinge rod 1524. At this time, the rubber plate 1523 generates an elastic force downward to support the upward blocking force of the connecting plate 151, and forms a lateral elastic support, so that the metal rod 142 has a lateral elastic effect, which can buffer the uneven roadbed when the resistance is too large. In addition, the support mechanism 15 of the present invention also blocks the intermittent activities of the rolling structure 12 to a certain extent, and enhances the elastic rolling effect of the rolling structure 12 when rolling under elasticity.

[0043] Working methods of highway subgrade compaction equipment used in road construction: S1: First, the roller 4 is controlled to move at the position of the compacting vehicle 2, so that the rolling mechanism 1 connected to the lower end of the vehicle head 5 and the roller 4 move horizontally, and the roadbed is compacted under the weight of the rolling mechanism 1 itself.

[0044] S2: When the rolling mechanism 1 contacts the roadbed for compaction, under the gravity of the gravity block 124, the rolling structure 12 rolls clockwise and rolls the roadbed, wherein when the rolling structure 12 rolls, the force rod 1233 in the force structure 123 rotates along with the rolling under the connection with the rolling strip 1232.

[0045] S3: After the load-bearing rod 1233 rotates, it reaches the outer position of the arc plate 11 and is blocked by the arc plate 11 during the rotation. Since the arc plate 11 is fixed by the metal rod 142, it blocks the load-bearing rod 1233 from driving the load-bearing plate 1231 to be squeezed outward from the gap of the rolling strip 1232. At this time, the six load-bearing structures 123 block the load-bearing structure 123 at the position of the arc plate 11 while rolling and strengthen the downward impact force on the roadbed.

[0046] S4: The force-bearing structure 123 is connected by the spring 13 when intermittently punching the roadbed, and rotates with the point of the bearing ring 141 on the outside of the metal rod 142 as the support point, so that the force-bearing structure 123 rolls while driving the rolling tube 122 to rotate, and the roadbed is rolled by the gravity of the gravity block 124. During this process, the gravity block 124 elastically squeezes the rubber ring 121 and drives the metal rod 142 and the bearing ring 141 to jump intermittently, and drives the force of the force-bearing structure 123 on the roadbed to perform intermittent impacts through the connection of the spring 13.

[0047] S5: Secondly, when the load-bearing structure 123 is stamped at intervals on the roadbed, the metal rod 142 connected at its center is fixed at the position of the limiting hole 153 in the connecting plate 151. The fluctuation caused by the stamping of the roadbed causes the connecting plate 151 to squeeze the metal sheet 154 upward, and causes the movable plate 1521 to drive the connecting plate 151 to rotate upward with the hinge rod 1524 as the center. At the same time, under the elasticity of the rubber plate 1523, the movable plate 1521 generates a downward rotation force, and the downward rotation force of the movable plate 1521 forms an elastic downward pressing at the inclined position above the connecting plate 151.

[0048] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.

After the rolling is blocked, the force-bearing rods (1233) are squeezed out from the gaps between the rolling strips (1232) and impact the roadbed.

6. A highway subgrade compaction equipment for road construction according to claim 1, characterized in that: The support mechanism (15) is provided with a connecting plate (151), a guide plate (152), a limiting hole (153), a metal sheet (154), and a rubber block (155); the outer end of the connecting shaft (14) is fixedly arranged in the connecting plate (151) inside the connecting plate (151); the rubber block (155) is arranged between the connecting plate (151) and the guide plate (152); the metal sheet (154) is arranged between the guide plate (152) and the connecting plate (151); the roller (4) moves and causes the vehicle head (5) to push the connecting shaft (14) in the middle of the limiting hole (153) to be compacted on the roadbed.

7. A highway subgrade compaction equipment for road construction according to claim 6, characterized in that: The metal sheet (154) and the connecting plate (151) are inclined at 40 degrees. When the connecting plate (151) drives the connecting shaft (14) to compact the roadbed, the resistance of the roadbed to the connecting shaft (14) acts in the opposite direction on the connecting plate (151), causing the connecting plate (151) to be pressed toward the guide plate (152) connected to the metal sheet (154).

8. The highway subgrade compaction equipment for road construction according to claim 6, characterized in that: The guide plate (152) is provided with a movable plate (1521), a support plate (1522), a rubber plate (1523), and a hinge rod (1524); the hinge rod (1524) is arranged on the side surface of the lower end of the support plate (1522); when the connecting plate (151) moves upward, it is blocked by the rubber block (155) and causes the connecting plate (151) to press the movable plate (1521) at the position of the metal sheet (154); after being pressed by the connecting plate (151), the movable plate (1521) rotates counterclockwise around the hinge rod (1524) and supports the connecting plate (151) under the elasticity of the rubber plate (1523); Working methods of highway subgrade compaction equipment used in road construction: S1: First, the roller (4) is controlled to move at the position of the compacting vehicle (2), so that the rolling mechanism (1) connected to the lower end of the vehicle head (5) and the roller (4) move horizontally, and the roadbed is compacted under the weight of the rolling mechanism (1); S2: When the rolling mechanism (1) contacts the roadbed for compaction, under the gravity of the gravity block (124), the rolling structure (12) rolls clockwise and rolls the roadbed, wherein when the rolling structure (12) rolls, the force rod (1233) in the force structure (123) rotates along with the rolling under the connection with the rolling strip (1232); S3: After the force-bearing rod (1233) rotates, it reaches the outer side of the arc plate (11) and is blocked by the arc plate (11) during the rotation. Since the arc plate (11) is fixed by the metal rod (142), it blocks the force-bearing rod (1233) from driving the force-bearing plate (1231) to be squeezed outward from the gap between the rolling strips (1232). At this time, the six force-bearing structures (123) block the force-bearing structures (123) at the position of the arc plate (11) while rolling and strengthen the downward impact force on the roadbed. S4: The force-bearing structure (123) is connected by a spring (13) when intermittently punching the roadbed, and rotates with the point of the bearing ring (141) outside the metal rod (142) as a support point, so that the force-bearing structure (123) rolls and drives the rolling tube (122) to rotate, and rolls the roadbed through the gravity of the gravity block (124). During this process, the gravity block (124) elastically squeezes the rubber ring (121) and drives the metal rod (142) and the bearing ring (141) to jump intermittently, and drives the force of the force-bearing structure (123) acting on the roadbed to perform intermittent impact through the connection of the spring (13); S5: Secondly, when the load-bearing structure (123) is punched at intervals on the roadbed, the metal rod (142) connected at its center is fixed at the position of the limiting hole (153) in the connecting plate (151). The fluctuation caused by the punching of the roadbed causes the connecting plate (151) to press the metal sheet (154) upward, and causes the movable plate (1521) to drive the connecting plate (151) to rotate upward around the hinge rod (1524). At the same time, under the elasticity of the rubber plate (1523), the movable plate (1521) generates a downward rotation force, and the downward rotation force of the movable plate (1521) forms an elastic downward pressing force at the inclined position above the connecting plate (151).
