Description

Technical Field

[0001] The invention relates to the technical field of construction machinery, and in particular to a traffic construction excavation device. Background Art

[0002] In the field of transportation infrastructure construction, construction excavation is an extremely critical and frequent work content. Traditional excavators have functional limitations and can only perform front shovel or backhoe operations. However, actual construction sites often need to flexibly switch excavation methods according to different work scenarios. Changing the excavation method requires changing the excavation equipment, which reduces the excavation efficiency. To improve this problem, a two-way bucket came into being. It can meet the project's needs for different excavation methods to a certain extent and improve work efficiency.

[0003] However, the existing two-way bucket will also have many problems that affect its efficiency during operation. For example, when there is water accumulation in the foundation pit, the excavation equipment will inevitably dig out the water together with the materials while digging the materials. For the overall excavation operation, digging out the water not only increases the load of the excavation equipment and consumes more energy, but the operation of digging out the water itself has no practical significance, but takes up a lot of operation time, which greatly reduces the overall operation efficiency. At the same time, the rock and soil materials in the foundation pit containing water have high viscosity and are easy to adhere to and stick to the inner wall of the bucket. As the operation continues, the residual material continues to accumulate, which will not only increase the dead weight of the bucket and increase the energy consumption of the excavation equipment, but also gradually reduce the effective volume of the bucket, reduce the single excavation volume, and thus affect the overall excavation efficiency.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0032] like Figures 1 to 9As shown, the embodiment of the present invention provides a traffic construction excavation device, including a bidirectional bucket, a partition 103 and an adjustment mechanism. The bidirectional bucket is arranged to rotate around its own axis. The rotation axis of the bidirectional bucket is set as the first axis, and the extension direction of the first axis is Figure 2 In the X direction of the figure, the partition 103 is slidably arranged in the bidirectional bucket along a first direction, the first direction is perpendicular to the extension direction of the first axis, the first direction is a straight direction or a bending direction around the first axis, and the partition 103 is slidably connected to the inner wall of the bidirectional bucket, and a first through groove 104 penetrating the partition 103 along the first direction is opened on the partition 103, and the partition 103 divides the interior of the bidirectional bucket into two parts connected by the first through groove 104; the adjustment mechanism includes a baffle, a push assembly and an auxiliary assembly, and the baffle is provided with two, two Baffles are arranged on the partition 103 and are respectively located on both sides of the partition 103 in the first direction, and a spacing is provided between the two baffles and the partition 103 respectively and both can approach the partition 103 and abut against the partition 103. When the baffles abut against the partition 103, the first through groove 104 can be blocked; the pushing assembly is used to control the distance between the baffle and the partition 103 when the bidirectional bucket is excavating; the auxiliary assembly is arranged on the partition 103, and is used to prompt the baffle to further approach the partition 103 when the baffle approaches the partition 103.

[0033] After the two-way bucket excavates materials with high viscosity, the materials are easily attached to the inner wall of the two-way bucket. Through the coordinated setting of the partition 103 and the two-way bucket, when the two-way bucket is unloading, the partition 103 is located above the materials. The partition 103 can move downward under its own gravity in the two-way bucket and scrape off the residual materials on the inner wall of the two-way bucket. During the next excavation, the capacity of the two-way bucket is still at the maximum state, thereby improving the excavation efficiency. A first through groove 104 is provided on the partition 103. When the two-way bucket excavates materials, water entering the two-way bucket will be discharged from the two-way bucket through the first through groove 104, thereby reducing the load of the two-way bucket and improving the excavation efficiency. A baffle is provided. After the two-way bucket has excavated the materials, one of the baffles will be located between the materials and the baffle 103 and below the materials. The baffle abuts against the baffle 103 under the action of the gravity of the materials, and the first through groove 104 is blocked. When the two-way bucket moves the materials, the materials inside will not leak out, thereby ensuring the excavation efficiency.

[0034] The bidirectional bucket includes a top plate 100, a bottom plate 101 and two side plates 102. The top plate 100 and the bottom plate 101 are arranged in parallel, and a distance is provided between the top plate 100 and the bottom plate 101. The two side plates 102 are respectively located on both sides of the partition plate 103 in the extension direction of the first axis, and each side plate 102 is respectively connected to the top plate 100 and the bottom plate 101. The partition plate 103 is respectively slidably connected to the top plate 100, the bottom plate 101 and the two side plates 102. When the bidirectional bucket excavates materials, the materials push the partition plate 103 to slide in the bidirectional bucket.

[0035] In this embodiment, each baffle includes a rotating shaft 106 and two movable plates 105. The rotating shaft 106 is located on one side of the partition 103 in the first direction, and the axial extension direction of the rotating shaft 106 is consistent with the extension direction of the first axis. One side of the two movable plates 105 is rotatably connected to the rotating shaft 106 respectively, and the two movable plates 105 are movably arranged on the partition 103 away from the side of the rotating shaft 106. The rotating shaft 106 can approach and move away from the partition 103 under the action of the pushing assembly; when the rotating shaft 106 moves relative to the partition 103, the movable plate 105 slides on the partition 103 along the second direction, and the second direction is perpendicular to the extension direction of the first axis; the two sides of each movable plate 105 arranged along the axial extension direction of the rotating shaft 106 are respectively slidably connected to the side plate 102, thereby reducing the probability of materials entering the two-way bucket being stuck between the partition 103 and the movable plate 105, so that the movable plate 105 can better contact with the partition 103 and the first through groove 104 can be better blocked. When the two-way bucket is not digging, an angle is formed between the two movable plates 105 and the partition 103 under the action of the pushing assembly. The two sides of the partition 103 in the two-way bucket can be connected through the first through groove 104, and the water on one side of the partition 103 in the two-way bucket can flow to the other side of the partition 103 through the first through groove 104. Only when the movable plate 105 is subjected to the force in the direction of approaching the partition 103 to overcome the action of the pushing assembly on the movable plate 105, the angle between the two movable plates 105 and the partition 103 will be reduced.

[0036] In this embodiment, the push assembly includes a first spring 110 and two sliding columns 111. A cavity 112 is provided inside the partition 103. The first spring 110 is arranged in the cavity 112, and the first spring 110 is extended and retracted along the third direction. The third direction, the second direction and the extension direction of the first axis are perpendicular to each other. The second direction is Figure 2 The Y direction in the third direction is Figure 2Z direction in the middle; two sliding posts 111 are slidably arranged in the cavity 112 along the third direction, and the two sliding posts 111 are located on both sides of the first spring 110 in the third direction, and one end of the two sliding posts 111 away from the first spring 110 passes through the partition 103 and is slidably connected to the partition 103, and each sliding post 111 can abut against two movable plates 105 in a baffle. When the two-way bucket is not excavating, each slide post 111 is in contact with a rotating shaft 106, and the four movable plates 105 in the two baffles are symmetrical about the partition 103, and the first spring 110 is in a compressed state; when the two-way bucket is excavating, the material will impact the two movable plates 105 on one side of the partition 103. The more the material is accumulated, the greater the force on the two movable plates 105 will be, and the greater the force of the two movable plates 105 on the corresponding slide posts 111 through the rotating shaft 106 will be, and the slide posts 111 will eventually retract into the partition 103, and the first through slots 104 will be blocked by two of the movable plates 105. The impact force of the flowing water on the two movable plates 105 is limited, the slide posts 111 will not completely slide into the partition 103, and the water will also flow out to the two-way bucket through the first through slots 104.

[0037] In this embodiment, each movable plate 105 is provided with a second through slot 113, and the number of the first through slot 104 and the second through slot 113 is provided in plurality, and the size of the first through slot 104 is larger than the size of the second through slot 113; when a spacing is provided between the movable plate 105 and the partition plate 103, the first through slot 104 can be communicated with the second through slot 113, and when the movable plate 105 abuts against the partition plate 103, the second through slot 113 and the first through slot 104 are alternately arranged in the extension direction of the first axis, and the first through slot 104 is arranged on the partition plate 103 and the second through slot 113 ... The more the number of second through grooves 113 on the movable plate 105 is, the smaller its own size is, the less material can pass through, and the more material is left in the two-way bucket, which indirectly improves the working efficiency of the two-way bucket. At the same time, since the first through groove 104 is larger than the second through groove 113, the small part of small material that can pass through the second through groove 113 can also better pass through the first through groove 104; when the baffle plate approaches the partition 103, the large amount of impurities between the baffle plate and the partition 103 cause the material to be lost from the first through groove 104 in large quantities.

[0038] In this embodiment, two groups of sliders 114 are fixedly installed on both sides of the partition 103 in the extension direction of the first axis, and the number of sliders 114 in each group of sliders 114 is multiple. The multiple sliders 114 in each group of sliders 114 are arranged along the second direction on the partition 103, and a spacing is provided between two adjacent sliders 114 in the same group of sliders 114. The inner wall of the bidirectional bucket is provided with multiple slide grooves 115, and the multiple slide grooves 115 are arranged on the two side plates 102. The number of slide grooves 115 on each side plate 102 is consistent with the number of a group of sliders 114, and each slider 114 is slidably arranged in a slide groove 115 along the first direction.

[0039] There are two auxiliary components, each of which includes a rotating shaft 120 and two adjustment components. The rotating shaft 120 passes through the partition 103 and one slider 114 in each slider group 114 along the extension direction of the first axis and is rotatably connected to the partition 103 and the corresponding slider 114 respectively. The rotating shaft 120 can slide along the second direction on the slider 114 and the partition 103, and the rotating shaft 120 located in the slider 114 can roll in the slide groove 115; the rotating shaft 120 is located on the side of the movable plate 105 away from the rotating shaft 106 in the second direction; each adjustment component includes a guide block 121, a belt 122 and a transmission part, and the partition 103 is provided with A first groove 123, the first groove 123 passes through the partition 103 along the third direction, two guide blocks 121 are provided, and the two guide blocks 121 are both slidably set in the first groove 123 along the second direction, the rotating shaft 120 passes through the first groove 123, and the two guide blocks 121 are located on both sides of the rotating shaft 120 in the third direction, and the two guide blocks 121 are respectively located on one side of the rotating shaft 120 close to the middle of the partition 103 in the second direction, and each guide block 121 is rotatably connected to a movable plate 105 in a baffle; the belt 122 is wound around the rotating shaft 120, and the two ends of the belt 122 are respectively fixedly connected to the two guide blocks 121.

[0040] The transmission part is arranged on the partition 103, and is used to make the rotating shaft 120 roll in the slide groove 115 after the guide block 121 moves away from the middle of the partition 103 along the second direction. Two adjustment components are located on both sides of the movable plate 105 in the extension direction of the first axis. When the adjustment components adjust the movable plate 105, the force on the movable plate 105 is more balanced. When the guide block 121 moves in the second direction away from the middle of the partition 103, it means that the two-way bucket encounters resistance from the material during excavation, and it also means that there is material in the two-way bucket. After the impact of the material in the two-way bucket on the movable plate 105 is reduced, the movable plate 105 can still continue to approach the partition 103, and finally the first through groove 104 is closed to ensure that the material will not leak out, and at the same time, the water in the two-way bucket is reduced.

[0041] In this embodiment, the transmission part includes a rotating ring 124, two gears 125, a rack plate 126, a second spring 127 and a third spring 128. The rotating ring 124 is located in the first groove 123, the rotating ring 124 is sleeved on the rotating shaft 120, and the rotating ring 124 is rotatably connected to the rotating shaft 120. The two gears 125 are rotatably arranged in the first groove 123, and there is a spacing between the two gears 125. The two gears 125 are located between the two guide blocks 121. The two guide blocks 121 have teeth on one side close to each other. Each guide block 121 has a plurality of teeth. 1 can mesh with a closest gear 125; when the two baffles are not subjected to external pressure, the two rack plates 126 are not meshed with the corresponding gear 125, and at this time, the teeth on the guide block 121 are located on the side of the gear 125 close to the middle of the partition 103 in the second direction. When there is only water in the two-way bucket or the movable plate 105 is not enough to push the guide block 121 to slide, the rotating shaft 120 will not contact the side plate 102, the rotating shaft 120 will not rotate, the first through groove 104 will not be closed, and the water in the two-way bucket will be discharged and will not be dug out. The rack plate 126 is slidably disposed between the two gears 125 along the second direction, and the rack plate 126 is respectively meshed with the two gears 125, the second spring 127 and the third spring 128 are both extended and retracted along the second direction, and the second spring 127 is located between the swivel 124 and the rack plate 126, and the two ends of the second spring 127 are respectively connected to the swivel 124 and the rack plate 126; one end of the third spring 128 is connected to a side of the rack plate 126 away from the second spring 127, and the other end of the third spring 128 is connected to the partition 103.

[0042] In this embodiment, the slider 114 through which the rotating shaft 120 passes is provided with a second groove 129 on one side close to the middle of the partition 103 in the second direction, and a rubber wheel 130 is sleeved on the rotating shaft 120, and the rubber wheel 130 is fixedly connected to the rotating shaft 120, and the rubber wheel 130 is located in the second groove 129. When the bidirectional bucket is not performing excavation operations, the rotating shaft 120 is farthest from the middle of the partition 103 under the action of the second spring 127 and the first spring 110, and the rubber wheel 130 is in contact with the side plate 103. 02 is not in contact; when the shaft 120 approaches the middle of the partition 103 along the second direction, the rubber wheel 130 can be connected with the side plate 102 in a rolling manner. When the shaft 120 approaches the middle of the partition 103, the rubber wheel 130 will be subjected to an extrusion force after contacting the side plate 102 in the slide groove 115, and the friction between the rubber wheel 130 and the side plate 102 will increase. When the partition 103 slides along the first direction, the rubber wheel 130 can better roll on the side plate 102 and drive the shaft 120 to rotate.

[0043] A fourth spring 132 is fixedly installed on one side of each guide block 121 away from the middle of the partition 103 in the second direction. The fourth spring 132 is located in the second groove 129. The fourth spring 132 is retracted along the second direction, and one end of the fourth spring 132 away from the guide block 121 is fixedly installed on the partition 103. The fourth spring 132 can cause the guide block 121 to slide toward the middle of the partition 103.

[0044] In this embodiment, an auxiliary wheel 131 is sleeved on the rotating shaft 120, the auxiliary wheel 131 is fixedly connected to the rotating shaft 120, and the belt 122 is wound around the auxiliary wheel 131. The diameter of the auxiliary wheel 131 is larger than the diameter of the rotating shaft 120, which can increase the contact area with the belt 122, and can better drive the belt 122 to move when the rotating shaft 120 rotates.

[0045] In this embodiment, a covering layer is provided on the partition 103, which separates the first groove 123 from the outside of the partition 103. The covering layer can be made of flexible fabric with ductility. The covering layer is connected to the guide block 121. When the guide block 121 slides on the partition 103, it can pull the covering layer to extend. The covering layer can prevent the material in the bidirectional bucket from entering the first groove 123 and affecting the transmission of the internal structure, and does not affect the sliding of the guide block 121 on the partition 103.

[0046] In this embodiment, the traffic construction excavation device also includes a frame 200 and two hydraulic cylinders 201. The bidirectional bucket is rotatably arranged on the frame 200. The two hydraulic cylinders 201 are located on both sides of the first axis in the first direction, and the two ends of the two hydraulic cylinders 201 are respectively rotatably connected to the bidirectional bucket and the frame 200. The top plate 100 is rotatably arranged on the frame 200 around the first axis. One end of the two hydraulic cylinders 201 is rotatably arranged on the top plate 100, and when one of the hydraulic cylinders 201 is extended, the other hydraulic cylinder 201 contracts. The two hydraulic cylinders 201 work together to rotate the bidirectional bucket on the frame 200, making it more convenient for the bidirectional bucket to excavate.

[0047] The working principle of a traffic construction excavation device provided in the above embodiment is:

[0048] First, extend the frame 200 into the foundation pit, and choose forward excavation or reverse excavation according to actual conditions. When the two-way bucket excavates a mixture of material and water, the material and water will push the partition 103 to move in the two-way bucket along the first direction, and the material will be intercepted by the partition 103 on one side of the two-way bucket, and the water will flow to the other side of the partition 103 through the second through groove 113 and the first through groove 104. The two movable plates 105 in contact with the material will be thrust to slide in the opposite direction on the partition 103 along the second direction, and the rotating shaft 106 between the two movable plates 105 will approach the partition 103 and push the sliding column 111 to slide in the cavity 112 along the third direction, and the first spring 110 is compressed again.

[0049] When the rotating shaft 106 in a baffle approaches the partition 103, the rotating shaft 106 will push the two movable plates 105 rotatably connected thereto to slide on the partition 103 along the second direction. Taking one of the movable plates 105 as an example, the movable plate 105 will push the guide block 121 connected thereto to slide in the second groove 129. When the guide block 121 slides, the fourth spring 132 will be compressed. At the same time, the guide block 121 will mesh with the corresponding gear 125. When the guide block 121 meshes with the gear 125, the gear 125 will be driven to rotate. The rotation of the gear 125 drives the rack plate 126 to approach the middle part of the partition 103 along the second direction; when the rack plate 126 moves, it will compress the third spring 128 and stretch the second spring 127. After the second spring 127 is stretched, it will apply a pulling force to the swivel 124. The swivel 124 drives the rotating shaft 120 to move in the direction close to the rack plate 126, and the rotating shaft 120 drives the rubber wheel 130 thereon to contact the side plate 102 in the two-way bucket.

[0050] When excavation continues, the partition 103 will continue to slide along the first direction in the two-way bucket. At this time, the sliding of the partition 103 will cause the rubber wheel 130 to roll on the side plate 102. The rolling of the rubber wheel 130 will drive the rotating shaft 120 to rotate. The rotation of the rotating shaft 120 drives the auxiliary wheel 131 to rotate. The rotation of the auxiliary wheel 131 pulls the guide block 121 on the partition 103 along the second direction away from the middle of the partition 103 through the belt 122, further promoting the sliding of the guide block 121; as the excavated material increases, the partition 103 moves to the extreme position in the two-way bucket. At this time, the movable plate 105 is completely in contact with the partition 103, and the first through groove 104 is also closed. In the process of the two-way bucket moving out of the foundation pit, the material in the two-way bucket will not leak out from the first through groove 104. When unloading, the partition 103 slides downward in the two-way bucket due to its own gravity, and the partition 103 scrapes off the residual material on the inner wall of the two-way bucket.

[0051] When the auxiliary wheel 131 pulls the belt 122, the rotating shaft 106 away from the material moves in the direction away from the partition 103 under the action of the sliding column 111 and the first spring 110. The rotating shaft 106 pulls the corresponding guide block 121 to slide toward the middle of the partition 103 through the movable plate 105. At the same time, the guide block 121 will pull the belt 122 to slide, and the belt 122 wrapped around the auxiliary wheel 131 is always in a taut state.

[0052] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
