Description

Technical Field

[0001] This utility model relates to the technical field of hazard removal equipment for tunnel faces, specifically to a combined excavator bucket device. Background Technology

[0002] After blasting at the tunnel face, dangerous structures such as boulders and loose rocks may exist on the face and excavation section. To avoid safety hazards to construction personnel and equipment, hazard removal is necessary before the blasted debris is removed. Currently, hazard removal mainly includes manual or mechanical methods. Mechanical hazard removal first uses a conventional bucket to sweep away loose rocks from the face and excavation section. However, due to the unevenness of the face and excavation section, conventional bucket structures can only remove relatively obvious boulders or loose rocks. Some loose rocks and other dangerous structures cannot be effectively cleared and may be at the critical point of falling. If touched during subsequent construction, they could fall and cause a safety accident. To ensure the safety of construction personnel and equipment, after the initial hazard removal using a conventional bucket, a second hazard removal is required at the working face using a hook structure. To ensure the adequacy of the second hazard removal, two hooks with opposite bending directions need to be used to perform hazard removal operations in different directions during the second hazard removal process.

[0003] Therefore, in the existing technology for hazard removal at the tunnel face and excavation section, it is necessary to first use the bucket for hazard removal, then replace the bucket with a hook for secondary hazard removal. This secondary hazard removal requires replacing the hook with two different types of hooks with different bending directions. After the secondary hazard removal, the hook is replaced with a conventional bucket, and finally, the bucket is used to excavate and load the crushed stone onto trucks. Therefore, using the existing bucket structure requires a considerable amount of time to replace the bucket body and hooks, severely impacting construction efficiency. Furthermore, currently only one of the bucket body or hook can be connected to the bucket; the remaining components must be stored separately when not in use, requiring a separate storage space, which occupies construction space and is inconvenient to access. Utility Model Content

[0004] The present invention aims to provide a combined excavator bucket device to solve the problem of low efficiency in the prior art during blasting and hazard removal at the tunnel face.

[0005] To solve the above problems, the present invention adopts the following technical solution: a combined bucket device, including a bucket body and a plurality of bucket teeth fixedly connected to the end of the bucket body, and a hazard removal part connected to the back of the bucket body, the hazard removal part being bent and rotatably connected to the bucket body.

[0006] The principles and beneficial effects of this application are as follows: In this application, multiple bucket teeth are fixedly connected to the end of the bucket body. These multiple bucket teeth are spaced apart along a straight line, enabling the bucket body and the bucket teeth to be used for primary hazard removal and subsequent excavation and loading of crushed stone. In addition, a curved hazard removal section is connected to the back of the bucket body. Under normal conditions, the hazard removal section will not interfere with the use of the bucket body and the multiple bucket teeth. When secondary hazard removal is required, simply rotate the bucket body to rotate the hazard removal section on the back of the bucket body to a usable angle. At this time, the bucket body and the hazard removal section can be directly used as a secondary hazard removal machine. At the same time, the hazard removal section in this application is rotatably connected to the bucket body. After the hazard removal section completes secondary hazard removal in one direction, it can be rotated to reverse the curvature of the hazard removal section. At this time, the bucket body and the hazard removal section can complete secondary hazard removal in another direction.

[0007] Therefore, by adopting the technical solution of this application, when carrying out hazard removal in one direction during primary and secondary hazard removal, it is not necessary to replace structures such as hooks after completing the primary hazard removal as in the prior art. Simply rotating and adjusting the angle of the bucket body allows the hazard removal section on the back of the bucket body to be rotated to a usable state, avoiding the time wasted when replacing usable parts and effectively improving hazard removal efficiency. In addition, the curved hazard removal section in this application is rotatably connected to the bucket body. Therefore, during secondary hazard removal, the hazard removal section can first complete secondary hazard removal in one direction. Then, by rotating the hazard removal section, the bending direction of the hazard removal section can be changed, and the hazard removal section can be used to complete the hazard removal operation in the second direction of the secondary hazard removal. There is no need to set up and replace the hook structure separately, which not only reduces costs but also improves hazard removal efficiency. After the entire secondary hazard removal, simply rotating the bucket body to a normal usable state is sufficient to complete subsequent operations. The operation is very simple and efficient.

[0008] In addition, since the hazard removal unit is directly rotatably mounted on the bucket body in this application, only the hazard removal unit needs to be rotated during use. Therefore, the technical solution in this application does not require a separate storage place for the bucket body or hook as in the prior art, which effectively saves the already limited space in the tunnel and reduces the cost and time of transportation when replacing different parts.

[0009] Preferably, as an improvement, the number of hazard removal parts is one or more. When the number of hazard removal parts is more than one, the multiple hazard removal parts are spaced apart along multiple bucket tooth arrangement directions.

[0010] In this solution, one or more hazard removal sections are installed on the bucket body according to the actual size of the bucket body and the actual needs of hazard removal, so as to achieve a better hazard removal effect. When there are multiple hazard removal sections, they are spaced apart along the arrangement direction of multiple bucket teeth so that when the bucket body rotates and moves, it can drive multiple hazard removal sections to rotate or move smoothly, thereby completing the hazard removal operation quickly and efficiently.

[0011] Preferably, as an improvement, the hazard removal part includes a hazard removal hook.

[0012] In this design, the hazard removal section is a hook-shaped structure that allows the bucket body to easily drive the hazard removal hook into the gaps between the suspended rocks to complete the hazard removal action.

[0013] Preferably, as an improvement, the back of the bucket body is fixedly connected to a mounting part, and the hazard removal part is rotatably connected to the mounting part.

[0014] In this design, the mounting part is fixedly connected to the back of the bucket body, and the hazard removal part is rotatably connected to the mounting part. Compared with the method of directly rotatably installing the hazard removal part onto the trenching body, the installation of the hazard removal part is more convenient in this design.

[0015] Preferably, as an improvement, the mounting part includes a mounting base and a rotating base that are fixedly connected to each other, and the hazard removal hook is rotatably connected to the rotating base; the end of the mounting base away from the bucket body protrudes from the end of the rotating base away from the bucket body, the side of the mounting base is provided with bolt holes, and the hazard removal hook is provided with through holes that are directly opposite the bolt holes.

[0016] Preferably, as an improvement, the hazard removal hook is integrally formed with a cylindrical seat, the outer wall of the cylindrical seat is tangent to the side wall of the part of the mounting seat that protrudes from the rotating seat, and the through hole is located on the cylindrical seat.

[0017] In this design, the mounting part consists of a mounting base and a rotating base that are fixed to each other. The thickness of the mounting base is greater than that of the rotating base, so that the end of the mounting base protrudes beyond the end of the rotating base. A cylindrical base is integrally formed on the hazard removal hook. The outer wall of the cylindrical base is tangent to the side wall of the mounting base that protrudes beyond the length of the rotating base, so that the hazard removal hook can fit against the side wall of the mounting base no matter what angle it rotates to. In this embodiment, bolt holes are provided on the side of the mounting base, and through holes are provided on the cylindrical base that are directly opposite the bolt holes. After inserting the bolts into the bolt holes and through holes, and locking the nuts on the bolts, the hazard removal hook can be stably fixed to the trenching body. The structure is simple, the connection is convenient, and the connection is stable.

[0018] Preferably, as an improvement, the bolt holes and through holes are arranged along the multiple bucket teeth arrangement direction, and the two ends of the through holes are provided with nut holes with a diameter larger than the through holes.

[0019] In this solution, bolt holes and through holes are arranged along the direction of multiple bucket teeth, and nut holes with a diameter larger than the through holes are set at both ends of the through holes. The nut holes are coaxial with the through holes. When the nuts in the prior art are threaded to the screw, the nuts are located in the nut holes, which can prevent the nuts from being loosened by collisions when the hazard removal part completes the secondary hazard removal, and improve the stability of the hazard removal part installation and connection.

[0020] Preferably, as an improvement, the mounting base is provided with a receiving hole with a diameter larger than that of the bolt hole, the receiving hole being coaxially arranged with the bolt hole and located on the side of the mounting base away from the rotating seat.

[0021] In this solution, when the bolt passes through the bolt hole and the through hole and is fixed to the nut in the prior art, the head of the bolt is located in the receiving hole, which avoids the bolt head being deformed and damaged by the impact of gravel or other objects when the hazard removal part completes the hazard removal operation, and effectively ensures that the bolt stably fixes the hazard removal part.

[0022] Preferably, as an improvement, the rotating seat has a rotating hole and a connecting hole arranged coaxially, the diameter of the rotating hole is larger than the diameter of the connecting hole, and the rotating hole is located between the connecting hole and the bucket body; a limit pin is fixedly connected to the cylindrical seat, the limit pin includes a small diameter section and a large diameter section, the small diameter section is rotatably engaged with the connecting hole, the large diameter section is rotatably engaged with the rotating hole, and the cylindrical seat is provided with a threaded fixing hole fixedly connected to the small diameter section.

[0023] In this design, after the rotating seat and mounting base are fixed to the bucket body, the rotating hole is located between the connecting hole and the bucket body. At this time, the large-diameter section of the limiting pin is confined within the rotating hole, and the small-diameter section passes through the connecting hole and is threadedly fixed to the threaded fixing hole on the cylindrical seat. On the one hand, the rotating seat and the bucket body fit together and are fixed, so that the rotating hole is in a sealed state. The large-diameter section is located within the rotating hole and can be well protected, ensuring that the hazard removal part can be rotated and adjusted stably. On the other hand, since the diameter of the connecting hole is smaller than the diameter of the rotating hole, the corresponding diameter of the large-diameter section is also larger than the diameter of the connecting hole. Therefore, during use, the connecting hole can play an axial limiting role for the large-diameter section, so that the hazard removal part can be stably connected to the rotating seat. Combined with the bolt structure connected on the mounting base, the hazard removal part can be more stably connected to the bucket body, ensuring that the hazard removal part can stably complete the secondary hazard removal operation.

[0024] Preferably, as an improvement, the cylindrical base has a welding hole that communicates with the threaded fixing hole.

[0025] Since the small-diameter section and the cylindrical seat are fixedly connected by a threaded fixing hole, the small-diameter section may loosen after prolonged use, causing the hazard removal hook to loosen and affecting the stability of the secondary hazard removal by the hazard removal hook. In this solution, a welding hole is opened on the cylindrical seat, which communicates with the threaded fixing hole. After the small-diameter section is fixed to the threaded fixing hole, the welding hole is used to weld the small-diameter section to the cylindrical seat, thereby improving the stability of the connection between the small-diameter section and the cylindrical seat.

[0033] Example 1 This embodiment is as shown in the attached figure. Figure 1 As shown: A combined bucket device includes a bucket body 1 and multiple bucket teeth 2 fixedly connected to the open end of the bucket body 1 by screws. The multiple bucket teeth 2 are arranged at intervals in a straight line along the width direction of the bucket body 1. Figure 2 In this embodiment, a hazard removal section is connected to the back of the bucket body 1. The hazard removal section is curved and rotatably connected to the bucket body 1. Figure 3In this embodiment, the hazard removal part is a curved hazard removal hook 3. To facilitate the installation and connection of the hazard removal hook 3, a mounting part is fixedly connected to the back of the bucket body 1, and the hazard removal part is rotatably connected to the mounting part. In addition, the number of hazard removal hooks 3 can be one or more. When the number of hazard removal hooks 3 is multiple, the multiple hazard removal hooks 3 are spaced apart along the arrangement direction of the multiple bucket teeth 2. Figure 2 The diagram shows a scenario where two hazard-removing hooks 3 are installed.

[0034] Specifically, in combination Figure 2 and Figure 3 In this embodiment, the mounting part includes a mounting base 4 and a rotating base 5 that are fixedly connected by an integral molding method. The mounting base 4 and the rotating base 5 have an arc-shaped surface on the side facing the bucket body 1 that fits against the outer side of the back of the bucket body 1. In this embodiment, the mounting base 4 and the rotating base 5 are fixedly connected to the bucket body 1 by welding. In other embodiments other than this embodiment, the mounting base 4 and the rotating base 5 can be fixed to the bucket body 1 by screws or other fixing methods, which will not be described in detail here.

[0035] Combination Figure 2 , Figure 3 and Figure 4 The end of the mounting base 4 furthest from the bucket body 1 protrudes beyond the end of the rotating base 5 furthest from the bucket body 1, making the thickness of the mounting base 4 greater than the thickness of the rotating base 5. The end of the hazard-removing hook 3 is integrally formed with a cylindrical base 6, combined with... Figure 5 The outer wall of the cylindrical base 6 is tangent to the side wall of the part of the mounting base 4 that protrudes from the rotating base 5. The side wall of the mounting base 4 has bolt holes 401. The cylindrical base 6 has through holes 601 that are directly opposite to the bolt holes 401. The bolt holes 401 and through holes 601 are arranged along the direction of the arrangement of multiple bucket teeth 2. Nut holes 602 with a diameter larger than the through holes 601 are opened at both ends of the through holes 601. The nut holes 602 are coaxial with the through holes 601. At the same time, the side wall of the mounting base 4 has a receiving hole 402 with a diameter larger than the bolt holes 401. The receiving hole 402 is coaxial with the bolt holes 401. When the bolt 7 in the prior art is connected to the bolt holes 401 and the through holes 601 and then fixedly connected to the nut 8, the head of the bolt 7 is located in the receiving hole 402, and the nut 8 is located in one of the nut holes 602.

[0036] Combination Figure 3 and Figure 5To ensure a stable rotatable connection between the cylindrical base 6 and the hazard-removing hook 3 and the rotating base 5, this embodiment provides a coaxially arranged rotating hole 501 and a connecting hole 502 on the rotating base 5. The diameter of the rotating hole 501 is larger than the diameter of the connecting hole 502, and the rotating hole 501 is located between the connecting hole 502 and the arcuate surface of the rotating base 5. A limiting pin 9 is fixedly connected to the cylindrical base 6. The limiting pin 9 includes an integrally formed large-diameter section 901 and a small-diameter section 902. The large-diameter section 901 rotatably engages with the rotating hole 501, and the small-diameter section 902 rotatably engages with the connecting hole 502. The outer wall of the small-diameter section 902 has an external thread. Figure 5 (The external thread is not shown in the figure). The cylindrical seat 6 has a threaded fixing hole 603 that is threadedly connected to the external thread on the small diameter section 902. One end of the small diameter section 902 passes through the connecting hole 502 and is fixedly connected by the threaded fixing hole 603. Relying on the axial limiting effect of the connecting hole 502 on the large diameter section 901, the cylindrical seat 6 can only rotate with the rotating seat 5 through the limiting pin 9 and cannot move along the axis.

[0037] The specific implementation process is as follows: In this embodiment, during normal use, the bucket body 1 and bucket teeth 2 are combined and used as a common bucket. At this time, the bucket body 1 and bucket teeth 2 can be used to complete the first hazard removal at the working face and the subsequent digging operation of blasting and breaking rocks at the working face. After the first hazard removal is completed, the bucket body 1 is driven to rotate so that the back of the bucket body 1 faces downward. At this time, the hazard removal hook 3 connected to the back of the bucket body 1 can complete the second hazard removal along the bending direction of the hazard removal hook 3.

[0038] After the hazard removal hook 3 completes the first and second hazard removal, manually tighten the nut 8 to loosen it from the bolt 7, and then remove it through the through hole 601 and the bolt hole 401. At this time, manually rotate the hazard removal hook 3 and the cylindrical seat 6 so that the hazard removal hook 3, the cylindrical seat 6 and the limiting pin 9 rotate 180° relative to the bucket body 1. The bending direction of the hazard removal hook 3 relative to the bucket body 1 is adjusted, and the through hole 601 is rotated to be coaxial with the bolt hole 401. Then, insert the bolt 7 into the bolt hole 401 and the through hole 601, and connect the nut 8 to the bolt 7 so that the cylindrical seat 6 fits and is fixed to the mounting base 4. The direction of the hazard removal hook 3 is adjusted. At this time, the bucket body 1 can be used to drive the hazard removal hook 3 to continue to complete the second hazard removal. At this time, the hazard removal direction is opposite to the previous adjustment direction of the hazard removal hook 3, which can achieve a more complete hazard removal effect. After the secondary hazard removal is completed, rotate the bucket body 1 to make the bucket teeth 2 rotate to the working state, and use the bucket to complete the operation of digging and loading crushed stone.

[0039] Example 2 The difference between Example 2 and Example 1 is as follows: Figure 6As shown, to prevent the small-diameter section 902 from loosening due to stress after a period of use, which could cause the cylindrical seat 6 and the hazard removal hook 3 to loosen and affect normal hazard removal operations, this embodiment has a groove on the side wall of the cylindrical seat 6. Figure 5 The threaded fixing hole 603 in the middle is connected to the welding hole 604. After the small diameter section 902 is threadedly fixed to the threaded fixing hole 603, the small diameter section 902 is welded to the cylindrical seat 6 in the welding hole 604, so that the small diameter section 902 is more firmly connected and fixed to the cylindrical seat 6, thereby improving the stability of the entire structure.

[0040] Example 3 The difference between Embodiment 3 and Embodiment 1 is that in Embodiment 1, there is only one bolt hole 401 and one through hole 601. In this embodiment, in order to improve the stability of the connection between the cylindrical base 6 and the mounting base 4, multiple pairs of through holes 601 and bolt holes 401 can be provided. When the cylindrical base 6 and the mounting base 4 are fixed, multiple bolts 7 can be used for fixing, thereby effectively ensuring the stability of the connection between the cylindrical base 6 and the mounting base 4, and making the hazard removal hook 3 complete the hazard removal operation more stably.
