Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering vehicle lock application technology, and in particular to a double-hook interlocking locking structure for the cargo bin of a mining engineering vehicle. Background Technology
[0002] As core equipment for mining and material transportation, the locking structure of the cargo bucket of a mining engineering vehicle directly affects the safety and operational efficiency of the transportation process. The cargo bucket locking structure must withstand the vibrations, bumps, and impact loads of materials under the complex conditions of mining terrain over long periods, thus requiring extremely high stability, reliability, and ease of operation. Currently, there are many types of cargo bucket locking devices for mining engineering vehicles on the market, but their core functions all revolve around the rapid locking and reliable securing of the cargo bucket to the tailgate, making them one of the key components ensuring the normal operation of the mining engineering vehicle.
[0003] Existing locking structures for mine engineering vehicle cargo buckets generally suffer from design flaws. Most adopt a single locking hook or a simple buckle design, resulting in a single locking point and concentrated stress. Under long-term vibration and impact, problems such as hook deformation and buckle loosening are prone to occur. In severe cases, the tailgate may even open unexpectedly, causing material to fall and posing significant hazards to traffic safety. At the same time, traditional locking structures often rely on manual operation or simple mechanical transmission, making the locking and unlocking process cumbersome and inefficient. This makes it difficult to meet the high-frequency loading and unloading and rapid turnover requirements of mining operations, thus restricting the overall construction progress. Therefore, this utility model proposes a double-hook interlocking locking structure for mine engineering vehicle cargo buckets. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a double-hook interlocking locking structure for the cargo bucket of a mining engineering vehicle, so as to improve the locking stability and ease of operation, and ensure the transportation safety and operational efficiency of the mining engineering vehicle.
[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a double-hook interlocking mining engineering vehicle cargo bucket locking structure is provided, including a mounting seat installed on the cargo bucket and a fixed seat installed on the tail door. A locking mechanism is installed inside the mounting seat, and a driving mechanism is installed at the rear of the mounting seat. The driving mechanism is connected to the locking mechanism so as to drive the opening and closing of the locking mechanism. The surface of the fixed base is welded with a connecting lock, and the end face of the connecting lock is mutually locked to the locking mechanism, so as to realize the quick locking and opening between the cargo box and the tail door through the locking connection between the locking mechanism and the connecting lock.
[0006] The present invention is further configured such that: the mounting base is in the form of a U-shape, and its two ends are respectively provided with extensions for mounting on the cargo hopper.
[0007] Through the above technical solution, the U-shaped mounting base can provide a stable installation space for the locking mechanism and the drive mechanism. The extensions at both ends can be firmly connected to the cargo bucket with fasteners such as bolts, ensuring that the mounting base will not shift during the movement of the mining vehicle, thus laying the foundation for the stability of the overall locking structure.
[0008] The present invention is further configured such that: the locking mechanism includes two guide rods installed on the side walls of the mounting base near the end face; the outer walls of the two guide rods are symmetrically sleeved and slidably connected with adjusting blocks near the middle position; the rear wall of the adjusting block is connected to the driving mechanism; stress springs are installed on opposite sides of the two adjusting blocks; locking blocks are bolted to the front walls of the two adjusting blocks; limit blocks are fixedly connected to the end faces of the two locking blocks; and the locking blocks are locked to the end faces of the connecting locks.
[0009] Through the above technical solution, the guide rod provides guidance for the adjusting block, ensuring that the adjusting block can only slide along the axial direction of the guide rod and avoid deviation; the drive mechanism can drive the adjusting block to move synchronously, thereby driving the locking block and the limit block to achieve opening and closing action; the stress spring is in a compressed state in the locked state, and its elastic force can act on the adjusting block, so that the locking block and the connecting locking parts are tightly fitted, enhancing the reliability of locking and preventing the locking from loosening due to vibration.
[0010] The present invention is further configured such that the four stress springs are arranged in two groups, and the stress springs are respectively sleeved on the outer walls of the two guide rods, while the end faces of the two groups of stress springs are respectively pressed against the inner walls of the two sides of the mounting base.
[0011] By using the above technical solution, the stress springs are divided into two groups and sleeved on the outer wall of the guide rod, which can make the force on both sides of the adjusting block uniform and avoid jamming when the adjusting block slides. The end face of the stress spring is pressed against the inner wall of the mounting base, which can form a stable elastic support. When the drive mechanism releases the constraint on the adjusting block, the stress spring can quickly push the adjusting block to reset, realize the rapid closing of the locking structure, and improve the operating efficiency.
[0012] The present invention is further configured such that: the driving mechanism includes a drive motor bolted to the center of the rear part of the mounting base, the output shaft of the drive motor passes through the rear wall of the mounting base, and a protrusion is fixedly connected to its end face, the outer wall of the protrusion is smoothly attached to the corresponding wall of the adjusting block on both sides.
[0013] Through the above technical solution, the drive motor provides the power source for the opening and closing of the locking structure. It is installed at the center of the rear of the mounting base, which can ensure that the output shaft is subjected to balanced force. When the drive motor drives the protrusion to rotate, the smooth outer wall of the protrusion will generate a lateral thrust on the two adjustment blocks. Due to the eccentric setting of the protrusion, during the rotation, it can push the adjustment blocks to separate to both sides along the guide rod or cause the adjustment blocks to close towards each other under the action of the stress spring, thereby realizing the opening and closing of the locking mechanism. The structure is simple and the transmission is efficient.
[0014] The present invention is further configured such that: the connecting lock is configured in an L-shape, and the end face of the connecting lock extends between the two lock blocks and is locked to the two lock blocks.
[0015] Through the above technical solution, one end of the L-shaped connecting lock is welded to the fixed base, and the other end can be precisely extended between the two lock blocks. Its structural design can complement the locking mechanism, ensuring that the lock blocks can clamp and lock the connecting lock from both sides, forming a double-hook interlocking effect. Compared with a single hook, the locking stability is greatly improved, effectively preventing the connecting lock from falling off.
[0016] The present invention is further configured such that: the end face of the connecting lock is symmetrically provided with lock grooves on both sides, and is locked to two lock blocks through the lock grooves, and is adapted to the limiting block.
[0017] Through the above technical solution, the lock groove on the end face of the connecting lock is adapted to the shape of the lock block. When locked, the lock block is inserted into the lock groove, which can limit the axial and radial displacement of the connecting lock. The limiting block fits tightly with the inner wall of the lock groove, further enhancing the firmness of the lock and forming a double limiting, which prevents the connecting lock and the lock block from sliding relative to each other when the mining vehicle is traveling on bumpy roads, ensuring that the locking structure is always in a stable state.
[0018] The beneficial effects of this utility model are as follows: 1. The double-hook interlocking locking structure for the cargo bin of a mining engineering vehicle proposed in this utility model forms an interlocking structure through the double locking blocks of the locking mechanism and the locking groove of the connecting lock. Combined with the elastic force of the stress spring, the locking stability is greatly improved, effectively solving the problem of easy loosening and disengagement of the traditional single locking hook, and ensuring the safety of the mining engineering vehicle during transportation. 2. The double-hook interlocking locking structure for the cargo bin of a mining engineering vehicle proposed in this utility model uses a drive motor to drive the convex transmission, thereby realizing the rapid opening and closing of the locking mechanism. It is convenient and efficient to operate and can meet the needs of high-frequency loading and unloading operations of mining engineering vehicles. At the same time, the overall structure is compact, easy to install and maintain, and highly applicable. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0022] like Figures 1-6 As shown, a double-hook interlocking locking structure for the cargo bin of a mining engineering vehicle includes a mounting base 1 installed on the cargo bin and a fixing base 2 installed on the tailgate. The mounting base 1 has an overall U-shaped structure, and its two ends are respectively provided with extensions for installation on the cargo bin. The U-shaped mounting base 1 can provide a stable installation space for the locking mechanism 3 and the drive mechanism 4. The extensions at both ends can be firmly connected to the cargo bin by fasteners such as bolts, ensuring that the mounting base 1 will not be displaced during the movement of the mining engineering vehicle, thus laying the foundation for the stability of the overall locking structure.
[0023] like Figure 5 and Figure 6As shown, a locking mechanism 3 is installed inside the mounting base 1. The locking mechanism 3 includes two guide rods 31 installed on the two side walls of the mounting base 1 near the end face. Adjusting blocks 32 are symmetrically slidably connected to the outer walls of the two guide rods 31 near the middle. The rear wall of the adjusting block 32 is connected to the drive mechanism 4. Stress springs 33 are installed on opposite sides of the two adjusting blocks 32. Locking blocks 34 are bolted to the front walls of the two adjusting blocks 32. Limiting blocks 35 are fixedly connected to the end faces of the two locking blocks 34. Position block 35 is locked to the end face of connecting lock 5. Guide rod 31 provides guidance for adjusting block 32, ensuring that adjusting block 32 can only slide along the axial direction of guide rod 31 and avoid deviation. Drive mechanism 4 can drive adjusting block 32 to move synchronously, thereby driving locking block 34 and limiting block 35 to achieve opening and closing action. Stress spring 33 is in a compressed state in the locked state, and its elastic force can act on adjusting block 32, so that locking block 34 and connecting lock 5 are tightly fitted, enhancing the reliability of locking and preventing locking loosening due to vibration. Four stress springs 33 are arranged in two groups, and each stress spring 33 is sleeved on the outer wall of the two guide rods 31. At the same time, the end faces of the two groups of stress springs 33 are pressed against the inner walls of the two sides of the mounting base 1. By dividing the stress springs 33 into two groups and sleeved on the outer walls of the guide rods 31, the force on both sides of the adjusting block 32 can be evenly distributed, avoiding jamming when the adjusting block 32 slides. The end faces of the stress springs 33 pressing against the inner wall of the mounting base 1 can form a stable elastic support. When the drive mechanism 4 releases the constraint on the adjusting block 32, the stress springs 33 can quickly push the adjusting block 32 to reset, realizing the rapid closing of the locking structure and improving the operating efficiency.
[0024] like Figure 5 As shown, a drive mechanism 4 is installed at the rear of the mounting base 1, and the drive mechanism 4 is connected to the locking mechanism 3 to drive the opening and closing of the locking mechanism 3. The drive mechanism 4 includes a drive motor 41 bolted to the center of the rear of the mounting base 1. The output shaft of the drive motor 41 passes through the rear wall of the mounting base 1, and a protrusion 42 is fixedly connected to its end face. The outer wall of the protrusion 42 is smoothly attached to the corresponding wall of the adjusting blocks 32 on both sides. The drive motor 41 provides a power source for the opening and closing of the locking structure. It is installed at the center of the rear of the mounting base 1 to ensure that the output shaft is subjected to balanced force. When the drive motor 41 drives the protrusion 42 to rotate, the smooth outer wall of the protrusion 42 will generate a lateral thrust on the adjusting blocks 32 on both sides. Due to the eccentric setting of the protrusion 42, during the rotation, it can push the adjusting blocks 32 to separate to both sides along the guide rod 31 or cause the adjusting blocks 32 to close towards each other under the action of the stress spring 33, thereby realizing the opening and closing of the locking mechanism 3. The structure is simple and the transmission is efficient.
[0025] like Figure 1 and Figure 5As shown, a connecting lock 5 is welded to the surface of the fixed base 2, and the end face of the connecting lock 5 is mutually locked to the locking mechanism 3. This allows for quick locking and unlocking between the cargo compartment and the tailgate through the locking connection between the locking mechanism 3 and the connecting lock 5. The connecting lock 5 has an overall L-shaped structure, and the end face of the connecting lock 5 extends between the two locking blocks 34 and is locked to the two locking blocks 34. One end of the L-shaped connecting lock 5 is welded to the fixed base 2, and the other end can precisely extend between the two locking blocks 34. Its structural design can complement the locking mechanism 3, ensuring that the locking blocks 34 can clamp and lock the connecting lock 5 from both sides, forming a double-hook interlocking effect. Compared with a single hook, the locking stability is greatly improved, effectively preventing the connecting lock 5 from falling off. The end face of the connecting lock 5 is symmetrically provided with locking grooves 51 on both sides, and is locked to the two locking blocks 34 through the locking grooves 51. At the same time, it is adapted to the limiting block 35. The locking grooves 51 on the end face of the connecting lock 5 are adapted to the shape of the locking blocks 34. When locked, the locking blocks 34 are inserted into the locking grooves 51, which can limit the axial and radial displacement of the connecting lock 5. The limiting block 35 is tightly fitted to the inner wall of the locking groove 51, further enhancing the firmness of the lock and forming a double limiting, which prevents the connecting lock 5 and the locking blocks 34 from sliding relative to each other when the mining vehicle is traveling on bumpy roads, ensuring that the locking structure is always in a stable state.
[0026] When this utility model is in use, if it is necessary to lock the cargo bin and the tailgate, the tailgate is closed, so that the end face of the connecting lock 5 extends between the two locking blocks 34; the drive motor 41 is started, and the drive motor 41 drives the protrusion 42 to rotate. During the rotation of the protrusion 42, the pushing force on the two adjusting blocks 32 gradually decreases. At this time, the stress spring 33 pushes the two adjusting blocks 32 to slide towards each other along the guide rod 31 under the action of the elastic force, which drives the locking block 34 and the limiting block 35 to move synchronously until the locking block 34 is inserted into the locking groove 51 of the connecting lock 5, and the limiting block 35 is tightly fitted with the inner wall of the locking groove 51, so as to lock the cargo bin and the tailgate. When it is necessary to disconnect the lock, start the drive motor 41 to reverse, the protrusion 42 rotates and generates a lateral thrust on the two side adjustment blocks 32, pushing the adjustment blocks 32 to separate to both sides along the guide rod 31, the stress spring 33 is compressed, the lock block 34 disengages from the lock groove 51, and the limit block 35 releases the constraint on the connecting lock 5, so that the tailgate can be opened for loading and unloading operations.
[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
