Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically a tensioning structure for the adjusting seat of a crusher movable jaw. Background Technology

[0002] Jaw crushers are key crushing equipment in basic industries such as mining, building materials, transportation, and water conservancy and hydropower. Their reliability and ease of maintenance significantly impact the overall efficiency of the production line. This equipment crushes materials through the periodic squeezing motion of a movable jaw plate and a fixed jaw plate. During this process, the movable jaw plate and its supporting component, the movable jaw adjusting seat, must withstand continuous high-intensity impacts and vibrations. The movable jaw adjusting seat is typically fixed to the inside of the crusher frame using tie rods and bolts; the stability of this connection directly affects the normal operation of the crusher.

[0003] However, in actual working conditions, due to the enormous crushing force and repeated impact characteristics, the bolted components traditionally used to secure the adjusting seat are prone to loosening, and may even break at stress concentration points. These bolts often have irregular designs, making replacement extremely cumbersome once damaged: typically, the movable jaw plate must be fixed first, related components such as the elbow plate must be disassembled, and then the adjusting seat must be moved to a specific position before disassembly and reassembly can proceed. This maintenance process is not only time-consuming and labor-intensive, but also poses certain safety risks when operating in confined spaces, and extends equipment downtime. Therefore, improving the ease of maintenance of the adjusting seat's securing components while continuously optimizing structural reliability has become a technical problem that needs to be solved in this field. Utility Model Content

[0004] The present invention aims to solve the above problems and thus provide a fastening structure for the adjusting seat of the moving jaw of a crusher that is easy to replace and maintain.

[0005] The technical solution adopted by this utility model to solve the aforementioned problem is: A fastening structure for a moving jaw adjustment seat of a crusher includes a crusher frame and a moving jaw adjustment seat disposed inside the frame. A lifting seat is provided above the moving jaw adjustment seat inside the frame. A fastening hole is provided on one side of the frame. A lifting slide groove is provided on the top surface of the moving jaw adjustment seat and a fastening slide groove is provided on the side surface of the moving jaw adjustment seat. A first bolt is installed on the lifting slide groove and a second bolt is installed on the fastening slide groove. Both the first bolt and the second bolt include a locking block, a pull rod, and a locking nut. The pull rod and the locking block are detachably connected. The first bolt has a locking block installed inside the lifting slide groove and can slide relative to the movable jaw adjustment seat. The other end of its pull rod passes through the lifting seat and is locked by a locking nut. The second bolt has a locking block installed inside the tensioning groove, which can slide relative to the movable jaw adjustment seat. The other end of its pull rod passes through the tensioning hole and is fitted with a locking nut.

[0006] Furthermore, the locking block has a threaded hole in the center, and the pull rod is threadedly connected to the locking block; this facilitates the assembly and disassembly of the pull rod and the locking block.

[0007] Furthermore, at least the second bolt's locking block is also provided with a hand handle on its side, which extends along the tensioning groove and has its other end outside the groove; this provides the operator with a convenient gripping and force application point, making it easier to operate when installing or adjusting the locking block's position in the groove and reducing the difficulty of adjustment.

[0008] Furthermore, the handheld lever is T-shaped, with its vertical outer end connected to the locking block, and the length of its horizontal section is greater than the width of the pull-fixing groove; this prevents the handheld lever from sliding completely into the groove, making it easier for the operator to position and apply force.

[0009] Furthermore, the hand lever and locking block are detachably connected, allowing the hand lever itself to be replaced as an independent component. If the hand lever is damaged during operation, it can be repaired or replaced separately without replacing the entire locking block assembly, increasing structural flexibility and ease of maintenance.

[0010] Furthermore, both the hoisting chute and the tensioning chute are T-shaped grooves, with the locking block located inside the countersunk head of the T-shaped groove. Its width is equal to the width of the countersunk head of the T-shaped groove, and its height is less than the height of the countersunk head of the T-shaped groove. This allows the locking block to slide smoothly within the groove without easily coming out. At the same time, the T-shaped groove structure can better withstand forces from all directions, which helps to improve the stability and reliability of the connection.

[0011] Furthermore, two hoisting slides and two tie slides are symmetrically arranged on the surface of the movable jaw adjustment seat, and at least one first bolt or one second bolt is installed in each hoisting slide and tie slide to improve the stability of the overall structure.

[0012] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are: This invention employs a detachable locking block and pull rod combination, utilizing the lifting and securing grooves on the movable jaw adjusting seat to allow the bolt locking block to slide within the grooves. When bolt replacement or maintenance is required, there is no need to disassemble the movable jaw plate, the elbow plate, or the entire adjusting seat, thus simplifying the operation process, reducing maintenance difficulty and downtime, and improving maintenance convenience and work efficiency.
