Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, and in particular to a waste grab bucket moving device and a waste storage pit. Background Technology

[0002] The garbage grab is a key piece of equipment for transferring garbage from the garbage pit to the incinerator feed inlet. After the garbage is collected, it is unloaded into the garbage pit. The garbage grab can reach into various parts of the garbage pit, grab the garbage and put it into the incinerator to ensure a continuous and stable supply of garbage to the incinerator.

[0003] Currently, waste storage pits in waste incineration power plants are equipped with at least several waste grab buckets. Each grab bucket consists of a main body (with an oil tank at the bottom) and grab jaws. Some are operational, while others serve as backups. When an operational grab bucket malfunctions and needs replacement, it is moved to the hoisting opening for repair. However, placing the grab bucket at the hoisting opening occupies the hoisting space for subsequent backup grab buckets. This means that when replacing a grab bucket, the original malfunctioning grab bucket must be moved out, and then the backup grab bucket moved into the hoisting opening. However, there are no specialized transfer tools for grab buckets at the hoisting opening. Ordinary transfer tools cannot adequately support the oil tank and grab jaws, making transfer difficult. This forces workers to frequently enter the waste pit to perform operations, making the work extremely inconvenient and posing significant safety hazards in the confined space. Utility Model Content

[0038] This utility model provides a garbage grab bucket moving device and a garbage storage pit to solve the technical problem of inconvenience in transferring garbage grab buckets after a malfunctioning grab bucket is moved to the lifting port in the prior art.

[0039] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0040] Please see Figures 1 to 5 The present invention provides a garbage grab bucket moving device, comprising:

[0041] Bottom platform 1, with pulley 12 installed at the bottom of bottom platform 1, pulley 12 for sliding bottom platform 1;

[0042] Support platform 2 is installed on bottom platform 1. Support platform 2 and bottom platform 1 form a ring of steps 3. Steps 3 are used to support the tip of the grab of the garbage crane grab bucket. Support platform 2 is provided with placement hole 210. Placement hole 210 is used for the oil tank drain nut of garbage crane grab bucket to enter and exit.

[0043] When the garbage grab needs to be transferred, the oil tank of the garbage grab is supported on the support platform 2, and the oil drain nut of the oil tank is placed in the placement hole 210. The tip of the grab is supported on the step 3. That is, the entire garbage grab is supported on the garbage grab moving device in an open posture. Then the user can transfer the garbage grab through the pulley 12.

[0044] As can be seen from the above application process, the oil tank of the garbage grab is supported on the support platform 2, and the support platform 2 is specially designed with a placement hole 210 for the oil drain nut of the oil tank, so that the oil tank and the main body on it can be placed stably. Since there is a ring of steps 3 between the support platform and the bottom platform, the steps 3 can support the tip of the grab of the garbage grab, so that the tip of the grab is located inside the edge of the bottom platform 1, preventing the tip of the grab from protruding outside the garbage grab moving device and dragging on the ground. This would hinder the transfer of the garbage grab and easily damage the garbage grab.

[0045] Compared with the prior art, the advantages of this embodiment are as follows: First, it can provide good support for the garbage grab bucket. The support platform 2 provides support for the oil tank and main body of the garbage grab bucket, and the design of the step 3 allows the bottom platform 1 to provide support for the tip of the grab bucket, thus providing excellent support conditions for the garbage grab bucket in the entire garbage grab bucket moving device; Second, it can facilitate the transfer of the garbage grab bucket. The garbage grab bucket is supported by the support platform 2 and the bottom platform 1, and sliding is achieved with the help of the pulley 12, making the transfer convenient.

[0046] In some specific embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, this embodiment provides a possible implementation structure of the support platform 2, which includes a mounting base 20 and a support plate 21. The support plate 21 is provided with placement holes 210. The top of the mounting base 20 is connected and fixed to the support plate 21, and the bottom of the mounting base 20 is connected and fixed to the bottom platform 1. Along one side of the support platform 2 to one side of the bottom platform 1, the radial distance of the mounting base 20 gradually increases to form a frustum-shaped structure. The support platform 2 is used to support the oil tank of the grab bucket as the main stress point, so as to avoid the grab bucket becoming unstable after the grab flaps are removed during the maintenance of the grab bucket. The mounting base 20 structure, which is smaller at the top and larger at the bottom, can transfer the upper load to a larger range of foundation structures, providing good support for the oil tank and its main body.

[0047] The radial distance of the mounting base 20 refers to the distance from the central axis of the mounting base to the outer surface of the mounting base on a horizontal cross section.

[0048] In this embodiment, as Figure 1As shown, the mounting base 20 includes multiple support columns 200 and multiple structural reinforcing ribs 201. One end of each support column 200 is fixedly connected to the support platform 2, and the other end is fixedly connected to the bottom platform 1. The multiple support columns 200 are regularly arranged around the perimeter of the support platform 2. A gap is left between adjacent support columns 200 for users to perform maintenance operations. Structural reinforcing ribs 201 are horizontally connected between adjacent support columns 200. The multiple structural reinforcing ribs 201 are connected end to end to form a structural reinforcing ring. The support platform 2 and the bottom platform 1 are connected by the support of multiple support columns 200, forming a hollow structure. The hollow structure design facilitates maintenance of the oil tank and the bottom of the lifting claw. Furthermore, the multiple support columns 200, together with the structural reinforcing ribs 201, can strengthen the hollow structure and ensure the support strength.

[0049] The materials used for the support column 200 and the structural reinforcing rib 201 are varied, including channel steel, I-beams, H-beams, and other steel bars. Those skilled in the art can choose according to actual needs.

[0050] In some specific embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, this embodiment provides a possible cooperative structure between the supporting platform 2 and the bottom platform 1. The height difference between the upper surface of the supporting platform 2 and the upper surface of the bottom platform 1 is 1-2m. The supporting platform 2 is a frustum-shaped platform, and the bottom platform 1 is a regular hexagonal prism-shaped platform. The supporting platform 2 and the bottom platform 1 are arranged coaxially. The distance from the center of the bottom platform 1 to its edge is 2m-3m, so that the distance from the inner edge to the outer edge of the step 3 is 1-2m. The height of a single grab bar of the garbage grab bucket is about 1-2m, and the height difference is 1- The 2m height can cover the natural hanging height of the grab flap. When the grab flap is open on the ground, the horizontal dimension from the center of the garbage grab bucket to the outer edge of the grab flap is about 1-2m. The distance from the inner edge to the outer edge of the step 3 is also 1-2m, which can cover the horizontal dimension of the grab flap. Therefore, when the support platform 2 supports the oil tank and main body of the garbage grab bucket, since the height difference is also 2-3m, the grab flap can be kept hanging down naturally and supported on the bottom platform 1, avoiding the tip of the grab flap from leaving the bottom platform 1 and dragging on the ground, causing damage to the grab flap and hindering the transfer.

[0051] In this embodiment, the upper surface diameter of the supporting platform 2 is 0.85m, the lower surface diameter of the supporting platform 2 is 1.78m, the side length of the bottom platform 1 is 0.6m, the length of opposite sides is 4.6m, the diagonal distance is 5.2m, the height difference is 1.4m, and the distance between the inner edge and the outer edge of the step 3 is 1.41m.

[0052] In some specific embodiments, such as Figure 3As shown, this embodiment provides a possible implementation structure of the bottom platform 1. The bottom platform 1 includes a table board 10 and a support framework 11; the table board 10 is fixedly laid on the support framework 11, and the support framework 11 is fixedly connected to the supporting platform 2; the support framework 11 includes a plurality of support beams 110 and a plurality of support rings 111 with different diameters; the plurality of support rings 111 are coaxially arranged, and support beams 110 are fixedly connected between adjacent support rings 111. The design of the plurality of support rings 111 in cooperation with the support beams 110 enables the entire support framework 11 to be "woven" into a spider web structure, which can effectively enhance the bearing capacity of the bottom platform 1.

[0053] In this embodiment, as Figure 3 shown, there are three support rings 111 with different diameters arranged concentrically. The three support rings 111 are hexagonal. Support beams 110 are connected between each hexagonal end of adjacent support rings 111. A plurality of support beams 110 converge and connect at the center of the hexagon. The support beams 110 at the connecting ends form a "rice" shaped structure, and support beams 110 are also connected between each side of adjacent support rings 111, and these support beams 110 are independent of each other.

[0054] Among them, the materials of the support beams 110 and the support rings 111 are diverse. They can be channel steels, or they can be steel bars such as I-beams and H-beams. Those skilled in the art can choose according to actual needs.

[0055] In this embodiment, as Figure 4 and Figure 5 shown, pulley members 12 are installed on the support framework 11. The pulley members 12 are regularly arranged on the periphery of the support framework 11. The pulley members 12 are located on the outermost support ring 111. The regular arrangement of the pulley members 12 can balance the distribution of the load on the bottom plate, increase the stability of the support, and facilitate movement at the same time.

[0056] Specifically, the pulley member 12 includes six driving motors and six universal wheels. Each driving motor is correspondingly传动连接 with a universal wheel. The universal wheels are fixed on the support framework 11, and the ways of the driving motor and the universal wheel are diverse. The driving motor can be directly connected to the universal wheel, or it can be传动连接 with the universal wheel by means of belt drive or gear drive. The universal wheel includes a rotatable bracket, a runner, a rotating shaft, etc. Those skilled in the art can choose the universal wheels in the prior art, and will not elaborate here too much.

[0057] In some embodiments, to improve the static support capacity of the device, six jacks are also installed on the support frame 11. The jacks are located near the casters. When the jacks are not in operation, the bottom of the jacks is located above the bottom of the pulley 12. The jacks can be mechanical or hydraulic. When the device is not moving, the mechanical jacks bear the force, which extends the service life of the wheels and enhances the stability of the grab bucket moving device.

[0058] In some embodiments, in order to increase the friction between the garbage grab bucket and the bottom platform 1, the surface of the platform 10 near the supporting platform 2 is provided with anti-slip patterns. The anti-slip patterns can be strip patterns, checkered patterns, or composite patterns. The material of the platform 10 can be stainless steel so that stainless steel patterns are laid flat on the platform.

[0059] Based on the above embodiments, a waste storage pit is provided below, comprising:

[0060] Pit body;

[0061] The garbage grabbing mechanism is located inside the pit;

[0062] The maintenance platform is located on the inner wall of the pit and has an inspection port located on the moving path of the garbage grabbing mechanism.

[0063] The garbage grab bucket mobile device is located at the maintenance access point.

[0064] When replacing a garbage grab bucket, first place the garbage grab bucket moving device at the maintenance opening. The bridge crane of the garbage grab mechanism will move the garbage grab bucket above the lifting opening, lower the garbage grab bucket onto the garbage grab bucket moving device, disconnect the wire rope and cable on the garbage grab bucket, and move the garbage grab bucket out of the lifting opening maintenance platform using the garbage grab bucket moving device. Then, use the garbage grab bucket moving device to move a spare grab bucket directly below the lifting opening, and finally connect and fix the wire rope and cable of the bridge crane to the spare grab bucket to complete the replacement.

[0065] During the replacement of the garbage grab bucket, the spare grab bucket is moved to a designated position on the unloading platform using a garbage grab bucket moving device. This improves the working environment of the spare grab bucket and reduces the frequency of workers entering the garbage pit. This makes the maintenance and upkeep of the garbage grab bucket more convenient.

[0066] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
