Description

Technical Field

[0001] The present invention relates to the technical field of loaders, in particular to a smelting furnace quick-change loading structure and a loader. Background Art

[0002] In road construction, particularly high-grade highways, loaders are used for operations such as excavation and filling in roadbeds, and for collecting and loading asphalt and cement concrete materials at material fields. They can also push soil, level the ground, and tow other machinery. Currently, the working mechanism of a loader typically consists of a linkage, a quick-change bracket, and a bucket, which are then articulated and connected to the loader vehicle. The bucket is connected to the movable end of the quick-change bracket, while the linkage is connected to the vehicle at one end and to the movable end of the quick-change bracket at the other. The linkage rotates the bucket through the movable end of the quick-change bracket to unload the material.

[0003] When loading the smelting furnace in a smelting plant, the loader cannot drive the bucket to extend into the root of the smelting furnace due to limitations such as the small smelting furnace feed port, the large space inside the furnace, and the high temperature. This is because, on the one hand, the hydraulic quick-change structure cannot adapt to the high temperature environment of the smelting furnace. The high temperature inside the furnace will damage the hydraulic structure, and the connecting rod mechanism can only be outside the smelting furnace feed port; at the same time, the connecting rod mechanism has a large movable space, which is also inconvenient to enter the smaller smelting furnace feed port. Therefore, the existing loader bucket can only reach the smelting furnace feed port and cannot unload materials deep into the smelting furnace, seriously affecting operating efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a quick-change loading structure and loader for a smelting furnace, which can realize the delivery of a bucket to different depth positions of the smelting furnace for unloading.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions: In the first aspect, a quick-change loading structure for a smelting furnace is provided, comprising a quick-change telescopic frame and a bucket, wherein the rear end of the quick-change telescopic frame is provided with a quick-change hanging plate, which is fixedly connected to the movable end of the quick-change bracket through the quick-change hanging plate, and the front end of the quick-change telescopic frame is hinged to the bucket; the rear side of the bucket is also provided with a pull rod ear plate, which is provided with an oblong hole, and the quick-change telescopic frame is provided with a slide rail, in which a slide rod is slidingly arranged, and the rear end of the slide rod is connected to the rear end of the quick-change telescopic frame by a telescopic oil cylinder, and the pull rod ear plate is hinged to the front end of the slide rod through the oblong hole.

[0006] As a further implementation method, the pull rod ear plate is arranged in the middle position of the rear side of the bucket, and bucket ear plates are further provided on the bucket on both sides of the pull rod ear plate.

[0015] The beneficial effects of the present invention are as follows: 1. The present invention adds a quick-change telescopic bracket of a set length between the bucket assembly and the quick-change bracket, allowing the loader to drive the bucket into the loading port of the smelting furnace through the quick-change telescopic bracket. The front end of the quick-change telescopic bracket can be extended into the loading port to send the bucket deep into the smelting furnace.

[0022] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0023] like Figure 4 As shown, the bucket of the existing loader 4 is connected to the movable end of the quick-change bracket, specifically through a quick-change hanging plate. One end of the connecting rod mechanism is connected to the vehicle, and the other end is connected to the movable end of the quick-change bracket. The connecting rod mechanism drives the bucket to rotate and unload materials through the movable end of the quick-change bracket. However, when the existing loader 4 is used to load materials into the smelting furnace at a smelting plant, the loader 4 cannot drive the bucket to extend into the root of the smelting furnace 5 due to limitations such as the small feed port of the smelting furnace 5, the large space inside the furnace, and the high temperature. This is because, on the one hand, the hydraulic quick-change structure cannot adapt to the high temperature environment inside the smelting furnace 5, and the high temperature inside the furnace will damage the hydraulic structure, and the connecting rod mechanism can only be outside the feed port of the smelting furnace; at the same time, the connecting rod mechanism has a large vertical movable space, which is also inconvenient to enter the smaller feed port of the smelting furnace. Therefore, the bucket of the existing loader can only be sent to the feeding port of the smelting furnace and cannot further unload materials into the deep part of the smelting furnace, seriously affecting the working efficiency.

[0024] Example 1 In a typical embodiment of the present invention, referring to Figure 1-Figure 3As shown, a quick-change loading structure for a smelting furnace includes a quick-change telescopic frame 2 and a bucket. The rear end of the quick-change telescopic frame 2 is provided with a quick-change hanging plate 2-4, which is fixedly connected to the movable end of the quick-change bracket through the quick-change hanging plate 2-4, and the front end of the quick-change telescopic frame 2 is hinged to the bucket; the rear side of the bucket is also provided with a pull rod ear plate 1-2, and the pull rod ear plate 1-2 is provided with an oblong hole. The quick-change telescopic frame 2 is provided with a slide rail, and a slide rod 2-2 is slidingly arranged in the slide rail. The rear end of the slide rod 2-2 is connected to the rear end of the quick-change telescopic frame 2 through a telescopic oil cylinder 3, and the pull rod ear plate 1-2 is hinged to the front end of the slide rod 2-2 through the oblong hole.

[0025] In this embodiment, a quick-change telescopic frame 2 of a set length is added between the bucket assembly 1 and the quick-change bracket, so that the loader can drive the bucket into the loading port of the smelting furnace 5 through the quick-change telescopic frame 2. The front end of the quick-change telescopic frame 2 can be extended into the feeding port of the smelting furnace to send the bucket to the depth of the smelting furnace 5. By changing the length of the quick-change telescopic frame, the bucket can be sent to different depths of the smelting furnace 5 for unloading.

[0026] like Figure 2 As shown, the bucket assembly 1 includes a bucket, and a bucket ear plate 1-1 and a tie rod ear plate 1-2 are provided on the rear side of the bucket, wherein the tie rod ear plate 1-2 is provided in one group and is located in the middle position of the rear side of the bucket; two groups of bucket ear plates 1-1 are provided and are located on both sides of the tie rod ear plate 1-2, an oblong hole is provided on the tie rod ear plate 1-2, and a hinge hole is provided on the bucket ear plate 1-1.

[0027] like Figure 3 As shown, the main body of the quick-change telescopic frame 2 is a slide 2-3, which is a long plate-like structure with a rectangular shape. Boom plates 2-1 are provided on both sides of the front end of the slide 2-3. The front end of the boom plate 2-1 extends out of the front end of the slide 2-3 and is provided with a hinge hole. The boom plate 2-1 is docked with the hinge hole of the bucket ear plate 1-1 and a pin is installed to realize the hinge connection between the bucket and the front end of the slide 2-3.

[0028] like Figure 3 As shown, two groups of limit plates 2-5 are provided in the middle position of the top of the slide 2-3. The two groups of limit plates 2-5 are vertically welded to the slide 2-3, and the limit plates 2-5 extend along the length direction of the slide 2-3, that is, the limit plates 2-5 are in the same direction as the length direction of the slide 2-3. A slide rail for the slide rod 2-2 to slide is formed between the two groups of limit plates 2-5. The slide rod 2-2 can slide along the length direction of the slide 2-3 between the two groups of limit plates 2-5, and the front end of the slide rod 2-2 can extend out of the front end of the slide 2-3.

[0029] Furthermore, a connecting portion is provided at the front end of the slide rod 2-2, and the connecting portion can be set as two sets of connecting arms. The distance between the two sets of connecting arms is greater than the thickness of the pull rod ear plate 1-2. A through hole is provided on the connecting arm. The two sets of connecting arms extend to both sides of the pull rod ear plate 1-2 and utilize the pin shaft to cooperate with the through hole and the oblong hole to realize the movable connection between the pull rod ear plate 1-2 and the front end of the slide rod 2-2.

[0030] The quick-change telescopic frame 2 of this embodiment is hinged to the bucket ear plate 1-1 and the pull rod ear plate 1-2 on the rear side of the bucket through the boom plate 2-1 and the front end of the slide rod 2-2. When the slide rod 2-2 extends forward in the slide rail formed by the two sets of limit plates 2-5, it can drive the bucket to flip over and realize unloading.

[0031] It can be understood that there are sliding grooves on the inner sides of the two groups of limiting plates 2-5, and the two side edges of the slide rod 2-2 slide in cooperation with the sliding grooves through the limiting structure. The limiting structure can be a raised structure, so that the slide rod 2-2 can slide along the length direction of the limiting plate 2-5 on the inner sides of the two groups of limiting plates.

[0032] like Figure 3 As shown, the rear ends of the two sets of limit plates 2-5 are flush with the rear ends of the slide 2-3, and the rear ends of the slide 2-3 are vertically connected to the mounting plate 2-8 along the width direction. The front side of the mounting plate 2-8 is perpendicular to the limit plates 2-5 and welded together. The rear ends of the limit plates are fixed by welding to the mounting plates 2-8, thereby improving the connection strength between the mounting plates and the slide 2-3.

[0033] The front side of the mounting plate 2-8 is provided with a hinge seat 2-6, which is located between the two sets of limit plates 2-5. The telescopic oil cylinder 3 is also provided in the two sets of limit plates 2-5, one end of which is hinged to the hinge seat 2-6 and the other end is hinged to the rear end of the slide rod 2-2. Figure 1 As shown, the extension direction of the cylinder rod of the telescopic cylinder 3 is toward the rear end, so the end of the cylinder rod of the telescopic cylinder 3 is hinged to the hinge seat 2-6. The extension of the cylinder rod can push the slide bar 2-2 to slide in the slide rail, so that the front end of the slide bar 2-2 extends out of the front end of the slide 2-3, and then drives the bucket to tip through the pull rod ear plate 1-2 to achieve unloading.

[0034] Since the slide bar 2-2 can only be extended and retracted in the limit plate 2-5, the front end of the slide bar 2-2 slides with the oblong hole of the ear plate of the pull rod 1-2, and the loading and unloading state switching of the bucket can be smoothly realized.

[0035] like Figure 3 As shown, two sets of quick-change hanging plates 2-4 are provided on one side of the mounting plate 2-8 away from the limiting plate 2-5. The quick-change hanging plates 2-4 are prior art and are used to connect with the movable end of the quick-change bracket.

[0036] To further enhance the overall structural strength of the quick-change telescopic frame 2, multiple sets of first reinforcing plates 2-7 are arranged in parallel along the length of the limit plate 2-5, between the limit plate 2-5 and the top surface of the carriage 2-3. These first reinforcing plates 2-7 are welded between the outer side of the limit plate 2-5 and the top surface of the carriage 2-3. Simultaneously, multiple sets of second reinforcing plates are welded between the mounting plate and the top surface of the carriage 2-3. The provision of these reinforcing plates enhances the overall structural strength of the quick-change telescopic frame.

[0037] The length of the sliding rod of this embodiment is greater than half the length of the quick-change telescopic frame, so that when the smelting furnace quick-change loading structure of this embodiment is installed, the loader can drive the quick-change telescopic frame to extend into the feed port of the smelting furnace 5 by at least half the length of the quick-change telescopic frame, thereby achieving the purpose of unloading the material into the depths of the smelting furnace.

[0038] In other examples, the quick-change telescopic rack 2 of different sizes can be replaced according to the depth of the smelting furnace 5 .

[0039] Example 2 In a typical embodiment of the present invention, referring to Figure 1-Figure 3 The figure shows a loader equipped with the quick-change loading structure for a smelting furnace described in Example 1. A quick-change bracket and a connecting rod mechanism are mounted on the loader. One end of the connecting rod mechanism is mounted on the vehicle, and the other end is connected to the movable end of the quick-change bracket. The rear end of the quick-change telescopic bracket is fixedly connected to the movable end of the quick-change bracket via a quick-change hanging plate, and the front end of the quick-change telescopic bracket is hinged to the bucket. By adding a quick-change telescopic bracket of a set length between the quick-change bracket and the bucket assembly 1, the quick-change telescopic bracket 2 is long and compact, and its structure is compact. It can pass through the narrow feed port and smoothly enter the smelting furnace cavity, completing unloading operations within the large internal space of the smelting furnace.

[0040] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
