Description

Technical Field

[0001] The utility model belongs to the technical field of mounting and hanging devices, in particular to a large pin shaft galvanized mounting and hanging device. Background Art

[0002] Hydraulic supports are important equipment used in mining projects to control pressure in coal mining faces. Many structural components in this equipment are connected and fixed using pins of different specifications. Some pins can have a diameter of up to Φ100mm and a length greater than 600mm. The total weight is approximately 30kg, and the largest can exceed 50kg. See the schematic diagram of the pin structure for details. Figure 1 Due to the harsh operating environment in mines, the pin surface needs to be galvanized to improve its corrosion resistance and extend its service life.

[0003] The company previously had a large galvanizing line for galvanizing parts such as the pins of hydraulic support products. However, at the start of galvanizing, the pins had to be manually moved from the loading frame to the bottom of the galvanizing pole bar in the hanging area. After installing the tooling (screws and hooks), they were lifted and hung on the galvanizing pole bar before being hoisted by a crane for the various galvanizing steps. After the galvanizing was completed, the pins had to be manually removed from the pole bar, the tooling removed, and then moved to the loading frame. This installation and removal process was extremely labor-intensive and labor-intensive for the operators, resulting in low production efficiency, making it difficult to maintain production schedules, and failing to meet production needs.

[0004] The manual installation and disassembly method for pin galvanizing has the following shortcomings:

[0005] (1) The operator's labor intensity is high and the labor cost is high.

[0006] (2) Production efficiency is low and production nodes are difficult to guarantee.

[0007] (3) There are great hidden safety risks in production, and operators are prone to accidents such as being injured during transportation, loading and unloading.

[0008] (4) The loading and unloading process can easily cause the pins to collide, reducing the quality of the pin galvanizing. Utility Model Content

[0030] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0031] In the description, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance. It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, removable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms based on specific circumstances.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Based on the current production scale, on-site conditions and cost factors, measures are taken from three aspects. The main technical design plan is divided into three parts, as follows:

[0035] like Figure 2-3 As shown, a large pin shaft galvanized hanging device includes a pin shaft flipping mechanism, which is arranged in the hanging area below the galvanized pole bar. The pin shaft flipping mechanism includes a bracket frame assembly 1, a right-angle plate 4 with through holes on two right-angled sides, and a hydraulic push assembly 5. A rotating shaft 7 is connected above the bracket frame assembly 1, and the rotating shaft 7 is rotatably connected to the long support plate 2 and the short bottom plate 3. The long support plate 2 and the short bottom plate 3 are rotatably connected to the rotating shaft 7 through hinges spaced apart from each other. The long support plate 2 and the short bottom plate 3 are provided with through holes near the rotating shaft 7. After the long support plate 2 and the short bottom plate 3 are rotated to a vertical state, bolts are used to pass through the through holes to fix the right-angle plate 4 to the long support plate 2 and the short bottom plate 3 to achieve angle locking of the long support plate 2 and the short bottom plate 3.

[0036] The support frame assembly 1 is rotatably connected to the hydraulic push assembly 5, and the push rod of the hydraulic push assembly 5 is rotatably connected to the bottom side of the long support plate 2. The hydraulic push assembly 5 is composed of a gear pump, an oil tank, a directional valve and a jack, and its function is achieved through the telescopic action of the jack.

[0037] An electric hoist and an electromagnetic chuck are installed above the long support plate 2, and the electromagnetic chuck is used to place the pin shaft flat on the long support plate 2. This solves the problem of manually transporting the pin shaft from the loading frame to the bottom of the galvanized pole bar in the hanging area, and manually moving it back to the loading frame after plating.

[0038] A pin flipping mechanism is installed in the hanging area below the galvanized pole bar, and the pin is mechanically operated to turn from the "flat" state of the electromagnetic suction cup to the "upright" state, which facilitates the installation of the hanging screw in the galvanized process hole 6.

[0039] The long backboard 2 is provided with a side panel 1, the surface of the side panel 1 is perpendicular to the rotating shaft 7, and the side panel 1 is provided with a step notch. The step notch cooperates with the bracket frame assembly 1 to realize that the long backboard 2 is horizontally fixed above the bracket frame assembly 1. The short bottom plate 3 is provided with a side panel 2, the surface of the side panel 2 is perpendicular to the rotating shaft 7, and the side panel 2 is provided with a step notch. The step notch cooperates with the bracket frame assembly 1 to realize that the short bottom plate 3 is horizontally fixed above the bracket frame assembly 1.

[0040] An arc plate 1 is provided on the lower side of the long backboard 2, which connects the long backboard 2 with the side plate 1, and an arc plate 2 is provided on the lower side of the short bottom plate 3, which connects the short bottom plate 3 with the side plate 2.

[0041] The setting of the side plates and the arc plates can provide safety protection for the operator and prevent the operator from stepping on air and falling when the flipping mechanism is working.

[0042] The number of hydraulic pushing components 5 is 2.

[0043] like Figure 4-6 As shown, the bracket frame assembly 1 includes 5 vertical rods, 3 vertical rods are provided on one side of the short base plate 3, and a horizontal short rod 1 is connected between the vertical rods, 2 vertical rods are provided on one side of the long back plate 2, and a horizontal long rod 1 is connected between the vertical rods, a horizontal short rod 2 is connected between the vertical rods on the short base plate 3 side and the long back plate 2 side, the bottom ends of the vertical rods on the long back plate 2 side are connected to the horizontal long rod 2, the horizontal long rod 2 is vertically connected to 3 horizontal long rods 3, and a horizontal short rod 3 is connected between the horizontal long rods 3, the bottom ends of the vertical rods on the short base plate 3 side are respectively connected to a horizontal long rod 3, a horizontal short rod 4 is connected between the horizontal short rod 3 and the horizontal long rod 2, the hydraulic pushing assembly 5 is rotatably connected to the horizontal short rod 4, and the bracket frame assembly 1 is used to connect and fix the short base plate 3 and the long back plate 2 to ensure that the two can be stably supported and rotate around the axis.

[0044] During galvanizing, use the electric hoist and suction cup to lift the pin and place it flat on the long support plate 2 of the pin flipping mechanism. Turn the pin flipping mechanism to stand the pin upright on the short base plate 3 (note that the end with the galvanizing process hole 6 is facing upwards). Screw on the mounting screw at the galvanizing process hole 6, then hang one end of the hook on the mounting screw and the other end on the galvanized pole bar to complete the mounting of the pin. For disassembly after galvanizing, perform the opposite operation.

[0045] In this embodiment, by raising the operating platform (i.e., the plane provided by the horizontal state of the long back plate and the short bottom plate of the pin shaft flipping mechanism) by 300 mm, the hook can be directly hung on the galvanized pole bar, and lifted by the production line crane and placed into the plating tank. At the same time, the problem of the pin shaft touching the bottom after entering the tank is avoided, which solves the physically demanding operation of manually lifting the pin shaft and hanging it on the pole bar after it is installed on the tooling.

[0046] The working principle is as follows: the long support plate 2 is used to place the pin shaft flat when hanging, and can rotate 90 degrees around the rotation axis 7. When not in use, the long support plate 2 is in a horizontal state. Figure 4 When working, first stand the long support plate 2 upright and fix it with the short bottom plate 3 to form an "L" shape structure, then return the long support plate 2 to the horizontal state to place the pin horizontally. Figure 5 When the "L" shaped structure rotates 90° around the axis 7, the lifting pin is rotated to the "upright" state. Figure 6 .

[0047] The short base plate 3 is used to support the bottom surface of the pin when it is upright and can rotate 90° around the rotation axis 7. When not in use, the short base plate 3 is always in a horizontal position. When in use, it is first fixed to the long support plate 2 in an "L" shape. Then, the short base plate 3 rotates with the long support plate 2 to an upright position. After the pin is placed on the long support plate 2, the "L" shape rotates 90° around the rotation axis 7 until the short base plate 3 is horizontal, and then it can support the pin to stand upright on the short base plate 3.

[0048] The utility model solves the problem of time-consuming and labor-intensive manual operation, improves safety and reliability, effectively reduces potential safety hazards, and can also reduce collisions and deformations caused during transportation, thereby improving product quality.

[0049] The pin shaft flipping mechanism is a mechanical device specially designed for turning the pin shaft from "flat" to "upright", including a long support plate 2, a short base plate 3, a bracket frame assembly 1 and a hydraulic pushing assembly 5. The hydraulic pushing assembly 5 pushes the long support plate 2 and the short base plate 3 to rotate, thereby achieving the purpose of uprighting the pin shaft.

[0050] The above description is only a specific embodiment of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions have been made with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and such modifications or replacements do not deviate from the essence of the corresponding technical solutions within the scope of the technical solutions of the embodiments, and they should all be covered by the scope of protection of the claims.
