Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically to a portable idler roller spacing measuring device. Background Technology

[0002] Idler assemblies are an essential component of belt conveyors, comprising the largest number of parts among their many components. They mainly consist of idlers and idler frames, supporting the conveyor belt and materials. They are crucial for ensuring the normal operation of the belt conveyor; therefore, the processing and installation quality of the idler assemblies are paramount. Idler frames are typical batch-welded structural components, and the idler spacing within the frame is a critical parameter that must be inspected. Typically, quality inspectors use measuring tapes for random checks, but this method lacks accuracy. Utility Model Content

[0003] To address the aforementioned technical problems with existing methods of measuring idler roller spacing using a measuring tape, the present invention aims to provide a portable idler roller spacing measuring device. This device employs a split structure, making it easy to carry. Furthermore, the split structure allows for telescopic adjustment, and the surface is marked with graduations. The device extends to match the idler roller spacing and then uses the graduations to obtain the spacing. The overall structure is simple, making measurement easy, convenient, and highly accurate.

[0004] To achieve the above objectives, the present invention provides a portable idler roller spacing measuring device, comprising an inner measuring rod and an outer measuring rod. The surfaces of the inner and outer measuring rods are provided with scales. The inner measuring rod is movably inserted into the outer measuring rod. The relatively distant ends of the inner and outer measuring rods are respectively provided with quick-release idler roller shaft heads. The quick-release idler roller shaft heads have the same structure as the shaft heads at the ends of the idler rollers and can be installed onto the idler roller frame. By placing the measuring device between two idler roller mounting supports on the idler roller frame, and installing the quick-release idler roller heads at the ends of the inner and outer measuring rods onto the idler roller mounting supports respectively, the inner and outer measuring rods extend and retract based on the idler roller spacing between the two idler roller mounting supports. The idler roller spacing is obtained through the scales on the surfaces of the inner and outer measuring rods.

[0005] Furthermore, both the inner and outer measuring rods are made of steel pipes.

[0006] Furthermore, the inner measuring rod and the outer measuring rod are fitted with a clearance.

[0007] Furthermore, the inner measuring rod and the outer measuring rod are provided with threaded interfaces at their relatively far ends, and one end of the quick-release roller shaft is provided with a threaded head corresponding to the threaded interface.

[0008] The portable idler roller spacing measuring device provided by this utility model adopts a split structure, which is easy to carry. Based on the split structure, it can be extended and retracted and has a scale on the surface. The idler roller spacing is obtained by extending and retracting to match the idler roller spacing and then measuring the idler roller spacing through the scale on the surface. The overall structure is simple, the measurement is simple and convenient, and the accuracy is high. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0016] The portable idler spacing measuring device provided by this utility model simulates the idler installed on the idler frame. The device has a split structure, which is easy to carry. Based on the split structure, it can be extended and retracted and has a scale on the surface. The idler spacing is obtained by extending and retracting to match the idler spacing and then using the scale on the surface. The overall structure is simple, the measurement is simple and convenient, and the accuracy is high.

[0017] See Figure 1 , Figure 2 The diagram shown is a structural schematic of a portable roller spacing measuring device 1000 provided by this utility model.

[0018] As shown in the figure, the portable idler roller spacing measuring device 1000 provided by this utility model includes three components: an inner measuring rod 100, an outer measuring rod 200, and a quick-release idler roller shaft head 300.

[0019] The inner measuring rod 100 and the outer measuring rod 200 are provided with scales on their surfaces;

[0020] The inner measuring rod 100 is movably inserted into the outer measuring rod 200. The relatively far ends of the inner measuring rod 100 and the outer measuring rod 200 are respectively provided with quick-release roller shaft heads 300. The quick-release roller shaft heads 300 have the same shaft head structure as the roller end. The quick-release roller shaft heads 300 can be installed on the roller frame 10.

[0021] In practical applications, the measuring device 1000 is positioned between two idler mounting supports 20 on the idler frame 10. The quick-release idler shaft heads 300 at the ends of the inner measuring rod 100 and the outer measuring rod 200 are respectively mounted on the idler mounting supports 20. The inner measuring rod 100 and the outer measuring rod 200 extend and retract based on the distance between the two idler mounting supports 20. The idler distance is obtained by observing the scale on the surfaces of the inner measuring rod 100 and the outer measuring rod 200. This method provides high accuracy in measuring the idler distance, ensuring consistency with the actual idler distance and effectively solving the problems existing in the prior art.

[0022] Specifically, both the inner measuring rod 100 and the outer measuring rod 200 are steel pipes. The inner measuring rod 100 and the outer measuring rod 200 are fitted with a clearance fit, which allows the inner measuring rod 100 and the outer measuring rod 200 to move relative to each other, thereby allowing for retraction.

[0023] Furthermore, the inner measuring rod 100 and the outer measuring rod 200 are provided with threaded interfaces at their relatively distant ends, and one end of the quick-release roller shaft head 300 is provided with a threaded head corresponding to the threaded interface. The inner measuring rod 100 and the outer measuring rod 200 are threadedly connected to the threaded head of the quick-release roller shaft head 300 through the threaded interface.

[0024] The other end of the quick-release idler roller head 300 is pre-made in various specifications according to the structure of the idler roller head. The thread size of the quick-release idler roller head 300 connected to the inner measuring rod 100 and the outer measuring rod 200 of different specifications remains unchanged. In this way, only one specification of inner measuring rod 100 and outer measuring rod 200 needs to be made. During measurement, the corresponding quick-release idler roller head 300 can be configured as needed. By using threaded connection, quick disassembly and installation can be achieved, which makes it easy to replace quick-release idler roller head 300 of different specifications.

[0025] The measuring device 1000 provided in this solution, such as... Figure 1 It can measure the spacing between inclined and horizontal idlers on the idler frame 10. By replacing the quick-release idler shaft head 300, it can also adapt to idlers of different specifications. The inner and outer measuring rods can be extended and retracted according to the measured spacing, and the installation spacing of the idlers can be directly measured through the size scale marked on the measuring rod.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
