[0002] Bucket wheel machine, also known as bucket wheel stacker and reclaimer, is a modern industrial bulk material continuous loading and unloading high-efficiency equipment. It has been widely used in bulk material storage yards such as ports, docks, metallurgy, cement, steel mills, coking plants, coal storage plants, power plants, etc. The operation of bucket wheel stacker and reclaimer has a strong regularity and is easy to realize automation. The control methods include manual, semi-automatic and automatic. Bucket wheel stacker and reclaimer is divided into two types according to the structure: boom type and bridge type. Some equipment only has one function of reclaiming, called bucket wheel reclaimer. The boom type bucket wheel stacker and reclaimer consists of more than 20 parts such as bucket wheel running mechanism, slewing mechanism, belt conveyor, tail car, pitch, water spray dust removal, wind and lightning protection grounding, counterweight, door seat, etc. When the bucket wheel machine is overhauled, it needs to be hoisted on the overhaul platform for overhaul. However, the current bucket wheel machine overhaul platform has some shortcomings, such as:

[0028] like Figure 1 and Figure 2As shown, a bucket wheel excavator maintenance platform disclosed in the utility model includes:

[0029] The platform body 1 is a rectangular parallelepiped frame structure, and a protective structure is provided at the bottom and four sides thereof;

[0030] There are at least two support rods 2, which are respectively connected to one side of the top of the platform body 1 and are symmetrically arranged;

[0031] A lower clamping plate 3, wherein the lower clamping plate 3 is fixedly connected to the support rod 2, and the support rod 2 passes through the lower clamping plate 3;

[0032] An upper clamping plate 4, wherein the upper clamping plate 4 is arranged parallel to the lower clamping plate 3, and the upper clamping plate 4 is fixedly connected to the top end of the support rod 2;

[0033] The clamping assembly 5 includes at least two groups of clamping assemblies 5. The clamping assembly 5 includes two clamping seats 51. The two clamping seats 51 are symmetrically arranged between the upper clamping plate 4 and the lower clamping plate 3. The two clamping seats 51 are rotatably connected to the brake roller assembly 52.

[0034] A driving mechanism 6 is connected to each group of clamping components 5 to drive the two clamping seats 51 to move closer to or away from each other.

[0035] The platform body 1 can be improved by using an existing maintenance platform, and a support rod 2 of a suitable size is selected and welded to one side of the top of the platform body 1. At least two support rods 2 are provided. According to the length of different maintenance platforms, a corresponding number of support rods 2 are provided to ensure the support strength;

[0036] The upper clamping plate 4 and the lower clamping plate 3 are welded to the top end of the support rod 2 to form a U-shaped structure with the support rod 2. The two clamping seats 51 of each clamping assembly 5 are symmetrically arranged between the upper clamping plate 4 and the lower clamping plate 3. The two clamping seats 51 are arranged on one side close to each other with a groove, and the groove is used to connect the brake roller assembly 52. ​​The brake roller assembly 52 consists of a roller and a brake part. The brake part can control the roller so that the roller can roll or be fixed.

[0037] The driving mechanism 6 includes a stud 61, which is arranged between the upper clamping plate 4 and the lower clamping plate 3, and the stud 61 is rotatably connected to the upper clamping plate 4 and the lower clamping plate 3. Nuts 62 are sleeved on both ends of the stud 61. The two nuts 62 correspondingly fix the two clamping seats 51. A guide rod 63 is arranged between the two nuts 62. The guide rod 63 passes through the nuts 62 and is fixedly connected to the upper clamping plate 4 / lower clamping plate 3. A transmission assembly 64 is arranged between the two studs 61.

[0038] The two ends of the above-mentioned stud 61 are rotatably connected to the upper clamp plate 4 and the lower clamp plate 3. The two nuts 62 are respectively arranged on the threads in two directions of the stud 61, and the nuts 62 are limited by the guide rod 63. When the stud 61 rotates, the nuts 62 can only move along the stud 61 instead of rotating therewith, thereby making the two nuts 62 approach or move away from each other, thereby realizing the adjustment of the distance between the two clamping seats 51 to adapt to the fixation of different positions of the bucket wheel excavator.

[0039] The transmission assembly 64 includes two transmission wheels 641, and the two studs 61 both pass through the upper clamping plate 4. The two studs 61 are coaxially fixedly connected to one end of the studs 61 passing through the upper clamping plate 4. A transmission belt 642 is wound around the two transmission wheels 641, and a driving motor 643 is coaxially fixedly connected to the top of one of the studs 61, and the driving motor 643 is fixedly connected to the upper clamping plate 4.

[0040] The arrangement of the transmission wheel 641 and the transmission belt 642 can ensure that the two studs 61 rotate at the same speed at the same time, ensure the consistency of the clamping degrees of the two clamping assemblies 5, and further ensure the stability of the fixation.

[0041] The transmission wheel 641 is a sprocket, and the transmission belt 642 is a chain.

[0042] The transmission wheel 641 and the transmission belt 642 are arranged as a sprocket chain structure, so that the transmission is more stable.

[0043] An annular sliding groove 53 is formed in the middle of the circumference of the braking roller assembly 52 .

[0044] By setting the annular groove 53 on the roller assembly, the cross section of which is a right-angle U-shaped structure, it can adapt to the fixed position of the pipeline on the bucket wheel excavator, especially the square pipe. By setting the width of the U-shaped structure to match the width of the square pipe, it can be fixed on the square pipe. At the same time, it can slide along the pipeline through the braking roller assembly 52, and the maintenance personnel can move on the maintenance platform to change the maintenance position.

[0045] The above specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0046] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0047] The above is a relatively specific and detailed description of the utility model through general description and specific embodiments. It should be pointed out that, without departing from the concept of the utility model, it is obvious that several variations and improvements can be made to these specific embodiments, which all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application shall be based on the attached claims.
