Description

Technical Field

[0001] This utility model relates to the technical field of grab bucket maintenance experimental system, specifically to a grab bucket maintenance workstation simulation device. Background Technology

[0002] In the waste incineration industry, grab buckets are core production tools for bulk material loading and unloading, and their maintenance and overhaul directly affect production continuity. During grab bucket maintenance, the positioning of the grab bucket structure is crucial to ensure the stability and safety of the maintenance work.

[0003] When conducting maintenance experiments, placing the grab bucket structure directly on the maintenance platform is not conducive to the maintenance of a single bucket or opening and closing mechanism. It requires the cooperation of a support and positioning structure, but there are the following problems: different grab buckets have different opening degrees when not in operation, and the support position of the fixed support and positioning structure is difficult to meet the support requirements, which poses a significant safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a grab bucket maintenance station simulation device with a reasonable structural configuration and safe and reliable use, to solve the problem of poor support stability for grab bucket structures with different opening degrees, to simulate the real maintenance state, and to ensure the support stability and safety when maintaining a single bucket or opening and closing mechanism.

[0005] The technical solution of this utility model is: A grab bucket maintenance station simulation device includes a maintenance platform and an adjustable support and positioning structure. The key technical features are: the adjustable support and positioning structure includes two fixed seats (left and right) fixed to the upper surface of the maintenance platform; an X-axis horizontal transmission screw supported between the two fixed seats; a left and right threaded sleeve symmetrically arranged on the X-axis horizontal transmission screw; a left movable seat connected to the left threaded sleeve; a right movable seat connected to the right threaded sleeve; a guide mechanism connecting the left and right movable seats; a front positioning assembly located on the front sides of the left and right movable seats; and a rear positioning assembly located on the rear sides of the left and right movable seats. The X-axis horizontal transmission screw is equipped with corresponding left and right threaded sleeves. The threaded sections of the threaded sleeve have opposite turns. The left and right moving seats are symmetrically arranged above the maintenance platform. They are respectively composed of a U-shaped seat body and an upper support body located in the middle of the U-shaped bottom of the U-shaped seat body. The top surface of the upper support body is a stepped surface and the middle vertical surface of the stepped surface is an inclined guide surface. The front positioning assembly and the rear positioning assembly respectively include a vertical plate, a Y-direction horizontal screw threaded to the upper part of the vertical plate, a handle located at one end of the Y-direction horizontal screw, a locking nut located on the Y-direction horizontal screw, and a positioning plate located at the other end of the Y-direction horizontal screw. The vertical plate is connected and fixed to the outer surface of the side wall of the U-shaped seat body. The positioning plates of the front positioning assembly and the rear positioning assembly are arranged opposite to each other.

[0006] The aforementioned grab bucket maintenance station simulation device includes a guiding mechanism comprising a horizontal guide rod fixed to the end face of the left moving seat and a linear bearing disposed in the right moving seat and cooperating with the horizontal guide rod. The horizontal guide rod is parallel to the X-direction horizontal transmission screw, and there are two horizontal guide rods symmetrically arranged on both sides of the X-direction horizontal transmission screw.

[0007] In the above-mentioned grab bucket maintenance station simulation device, the front positioning components of the left and right moving seats share a positioning plate, namely the front positioning plate, and the rear positioning components of the left and right moving seats share a positioning plate, namely the rear positioning plate. The front and rear positioning plates are parallel to each other and perpendicular to the Y-direction horizontal screw.

[0008] The above-mentioned grab bucket maintenance station simulation device has a removable buffer pad layer on the upper surface of the side wall of the U-shaped seat.

[0009] In the aforementioned grab bucket maintenance station simulation device, one of the fixed bases is equipped with a motor reducer connected to one end of the X-direction horizontal transmission screw.

[0010] The beneficial effects of this utility model are: 1. The left and right side walls of the central hinge box of the grab bucket structure are supported by the upper supports of the left and right moving seats. The two buckets of the grab bucket structure are supported by the U-shaped seat side walls of the left and right moving seats, and are positioned using front and rear positioning components. After positioning, the opening and closing mechanism of the grab bucket structure can be deactivated, facilitating maintenance operations such as replacement or online maintenance. Individual buckets can also be replaced, ensuring support stability and safety during maintenance.

[0011] 2. The left and right moving seats can adjust their spacing according to the width of the central hinge box of the grab bucket structure to ensure effective support for the left and right side walls of the hinge box. At the same time, by adjusting the spacing of the front and rear positioning components, effective positioning of grab bucket structures with different opening degrees can be ensured. It has a wide range of adaptability and is conducive to the maintenance simulation of different grab bucket structures. Attached Figure Description
