[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] As mentioned above, in the prior art, both ends of the rotating shaft are generally supported by bearings, and the ends of the rotating shaft are then connected to the rotating shaft driving source. The rotating shaft is driven by the rotating shaft driving source to rotate relative to the bearings. For long-term fixed structures, the rotating shaft supported by bearings is stable; however, in some usage scenarios, the rotating shaft needs to be disassembled frequently, for example: the conveyor belt of a self-unloading ship is put into the warehouse, and the rotating shaft needs to be reinstalled each time it is used. The rotating shaft supported by bearings needs to use upper and lower sleeves during installation, which requires relatively high installation precision. For this reason, the inventor of the present invention wants to redesign a rotating shaft tooling that does not require the use of bearings and sleeves and can be directly assembled to the rotating shaft bracket for use.

[0027] In order to solve the above problems, the utility model discloses a belt shaft tooling. When in use, the main body of the shaft is inserted into the central hole of the belt, the two ends of the shaft are placed on the shaft bracket, and a shaft driving source is arranged at one end of the shaft to drive the shaft to rotate;

[0028] Reference Figure 1 and Figure 2 As shown, the belt shaft tooling includes: a shaft body 1, a sleeve 2 and an adapter block 3, wherein: the shaft body 1 is a rod-shaped structure, the sleeve 2 is sleeved outside the shaft body 1, both ends of the shaft body 1 pass through the sleeve 2 and protrude from the sleeve 2, one end of the shaft body 1 protruding from the sleeve 2 is connected to the shaft drive source, and the shaft drive source drives the shaft body 1 to rotate relative to the sleeve 2, the adapter block 3 is arranged outside the sleeve 2, and the adapter block 3 can be clamped It is connected to the base slot of the shaft bracket to realize quick assembly of the shaft tooling and the shaft bracket, thereby realizing the fixation of the sleeve 2. When the shaft driving source drives the shaft body 1 to rotate, the sleeve 2 can support and fix the shaft body 1 and does not rotate with the shaft body 1. The shaft body 1 is passed through the center hole of the belt, so that the belt can be easier to enter the warehouse. Compared with the method of supporting the shaft with bearings, the utility model uses the sleeve 2 to support the shaft, which is faster to install and does not require precise assembly and matching, saving time and effort.

[0029] Specifically, in this embodiment, in order to enable the shaft body 1 to rotate relative to the sleeve 2, it is necessary to set a clearance fit between the sleeve 2 and the shaft body 1 so that the sleeve 2 can limit the shaft body 1 without affecting the rotation of the shaft body 1. In actual use, a clearance of 2 to 3 mm is generally reserved between the sleeve 2 and the shaft body 1, and lubricating oil is coated between the sleeve 2 and the shaft body 1 to reduce the rotational friction between the sleeve 2 and the shaft body 1, so that the rotation of the shaft body 1 is smoother.

[0030] Reference Figure 3As shown, in the present embodiment, the adapter block 3 is welded to the outside of the sleeve 2, which can ensure the stability of the connection between the adapter block 3 and the sleeve 2. In other implementations, the adapter block 3 can also be fixed to the outside of the sleeve 2 in other ways, for example: a clamping structure is provided between the adapter block 3 and the sleeve 2, or the adapter block 3 and the sleeve 2 are integrally formed. A variety of connection methods can be adopted according to actual usage requirements. These connection methods are all existing technologies and are not limited here one by one.

[0031] Specifically, in this embodiment, the adapter block 3 is provided to include a bottom plate support block 31 connected to the sleeve 2 and a bottom plate 32 connected to the base slot. The bottom plate 32 is welded on the bottom plate support block 31. The bottom plate 32 can be inserted into the base slot and connected to the shaft bracket. Generally, in order to ensure the stability of the connection between the bottom plate 32 and the base slot, a protruding contour portion is provided on the bottom plate 32, and the contour portion cooperates with the base slot.

[0032] The rotating shaft of the utility model is inserted into the center hole of the belt when it is actually used. The shape of the rotating shaft body 1 is set according to the shape of the center hole of the belt. For example, in this embodiment, the center hole of the belt is a square hole. Then, in this embodiment, referring to Figure 4 As shown, the shaft body 1 is provided to include: a square shaft 11 located in the middle and round steels 12 arranged on both sides of the square shaft 11, the square shaft 11 is matched with the center hole of the belt, the round steel 12 is connected with the shaft driving source and is driven to rotate by the shaft driving source, and the sleeve 2 described in this embodiment is provided with a transfer block 3, in order to match the shaft bracket, therefore, the sleeve 2 is sleeved outside the round steel 12.

[0033] Specifically, the square shaft 11 is a hollow shaft made by splicing four rectangular plates end to end. In order to further enhance the supporting strength of the square shaft 11, a reinforcing elbow plate 13 is also provided in the square shaft 11. The number of reinforcing elbow plates 13 is determined according to the actual length of the square shaft 11. When only one reinforcing elbow plate 13 is provided, the reinforcing elbow plate 13 is provided at the center position of the square shaft 11. When multiple reinforcing elbow plates 13 are provided, the multiple reinforcing elbow plates 13 are distributed in the square shaft 11 at equal intervals along the axial direction.

[0034] Specifically, in other embodiments, when the central hole of the belt is a circular hole, the rotating shaft body 1 can be correspondingly set to be a circular shaft.

[0035] In this embodiment, in order to enhance the strength of the rotating shaft body 1, the round steel 12 is partially embedded in the square shaft 11 to ensure that there is a large overlap between the round steel 12 and the square shaft 11, and then the round steel 12 is partially welded to the direction shaft to ensure the stability of the connection.

[0036] Reference Figure 1 and Figure 2 As shown, baffles 4 are also provided at both ends of the square shaft 11. The baffles 4 are provided between the square shaft 11 and the round steel 12. The baffles 4 protrude from the square shaft 11 in the radial direction. The purpose of providing the baffles 4 is to limit the position of the belt roll and prevent the belt roll from shifting.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
