[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Example 1: Figures 1 to 6 The shown set of adjustable roller beam detection tooling for belt conveyors includes a plurality of connecting rods 1 fixedly connected together. The number of connecting rods 1 can be set according to the standard spatial length designed for the roller beam 6. In this embodiment, there are 2 connecting rods 1, wherein the connecting rods 1 are seamless steel pipes, which have the advantages of high strength and light weight. Adjacent connecting rods 1 are fixedly connected by double-headed connecting nuts 11, which have the advantages of firm connection and easy installation. The outer ends of the two outermost connecting rods 1 are respectively connected with shaft rods 2, wherein the outer ends of the two shaft rods 2 are provided with slots 21, the shaft rod 2 extends into the connecting rod 1 or the connecting rod 1 extends into the shaft rod 2, the two are telescopically connected, and the connection length is freely adjusted, and the telescopic connection of the two is fixedly connected through a fastening device, that is, the connecting rod 1 and the shaft rod 2 are first connected to the two ends of the fastening device respectively, and then the connection length of the shaft rod 2 and the connecting rod 1 is adjusted according to the designed standard length, and the fastening device is tightened. At this time, the connecting rod 1 and the shaft rod 2 are fixedly connected together, and finally the connected detector is connected to the roller beam 6, that is, the slots 21 of the shaft rod 2 are hung in the slots at both ends of the roller beam 6, so that it can be detected whether the spatial length of the measured roller beam 6 meets the standard. If the slots 21 at both ends can be snapped into the slots at the corresponding ends of the roller beam 6, it means that the spatial length of the measured roller beam 6 meets the standard length, otherwise it does not meet the standard.

[0026] The detector can select a corresponding number of connecting rods 1 according to the standard length of the roller beam 6 to be tested and fixedly connect them together, and can be telescopically connected to the connecting rod 1 through the shaft rod 2, adjust the shaft rod 2 and the connecting rod 1 to the accurate standard length, and then use the fastening device to fix the shaft rod 2 and the connecting rod 1. The detector with adjustable length can detect roller beams 6 of various spatial lengths, and has the beneficial effects of wide detection range, easy use, high measurement accuracy and detection efficiency.

[0027] Embodiment 2: Based on the embodiment 1, an optimal design is performed, and an extension rod 3 is further provided between the connecting rod 1 and the shaft rod 2. The extension rod 3 is also a seamless steel pipe, wherein the two ends of the extension rod 3 are respectively selected to be telescopically connected or threaded, that is, one end of the extension rod 3 is fixedly connected to the shaft head 22 by a thread, and the other end is telescopically connected to the connecting rod 1 and fixed by a fastening device, or one end of the extension rod 3 is fixedly connected to the connecting rod 1 by a thread, and the other end is telescopically connected to the shaft rod 2 and fixed by a fastening device. The fastening device is selected to be a locking device 4, which is a conventional standard accessory, and its working principle is to achieve clamping through an internal fastening mechanism, and the clamping force can be adjusted as needed. When in use, after adjusting the connection length of the telescopic connection of the extension rod 3, tighten the locking device 4, and the parts connected at both ends of the locking device 4 can be fixed together. In addition, if the detector does not need to add an extension rod 3 when it is actually used, the locking device 4 directly fixes the connecting rod 1 with the adjusted connection length to the shaft rod 2. The provision of the extension rod 3 can further increase the length adjustment range of the locker 4, and can be adapted to the spatial length test of more models of roller beams 6.

[0028] Embodiment 3: Based on the embodiment 1, a preferred design is made, in which a shaft head 22 is fixed to the outer end of the shaft rod 2, the shaft rod 2 and the shaft head 22 are integrally connected, and a roller disc 5 is sleeved on the shaft body, and the diameter of the shaft head 22 is larger than the diameter of the shaft rod 2 and the inner diameter of the roller disc 5, thereby limiting the roller disc 5 from falling out from the shaft head 22 end. The slot 21 is set on the shaft head 22, and the corresponding roller will be installed on the measured roller beam 6, and the diameter of the roller disc 5 is the same as the roller diameter of the roller, and the distance between the outer end face of the roller disc 5 and the slot 21 is the same as the distance between the end face of the roller of the roller and the corresponding flat square groove. By installing the roller disc 5 on the shaft rod 2 and the diameter of the installed roller disc 5 and the distance between the roller disc 5 and the slot 21 are consistent with the corresponding roller, the situation where the roller is installed on the roller beam 6 can be fully simulated, and whether there is interference between adjacent rollers installed on the roller beam 6 can be detected, and whether the roller beam 6 meets the standard can be further detected, thereby improving the accuracy of the detection result.

[0029] Furthermore, a plurality of grooves 51 are provided on the inner annular surface of the roller 5, and a clamping block 23 having the same number and opposite position as the grooves 51 is provided on the outer end of the shaft 2. The clamping block 23 can pass through the groove 51, and the distance between the clamping block 23 and the inner side surface of the shaft head 22 is the same as the thickness of the roller 5. During installation, the roller 5 is first passed through the inner end of the shaft 2, and then the position of the groove 51 and the clamping block 23 are aligned, the roller 5 is passed through the clamping block 23, and then the roller 5 is rotated, and the roller 5 is clamped between the clamping block 23 and the shaft head 22.

[0030] Preferably, the number of the grooves 51 is 2, and the number of the clamping blocks 23 is also 2, so that the roller disc 5 can be stably clamped and the roller disc 5 can pass through the clamping blocks 23 easily.

[0031] Furthermore, the diameter of the shaft head 22 is the same as the shaft diameter of the roller to be installed on the roller beam 6, and the size and structure of the slot 21 are also consistent with the flat square slot of the corresponding roller. The detector produced by this design can further increase the authenticity of the simulated roller installed on the roller beam 6 and improve the accuracy of the test. And in actual use, it is only necessary to select the corresponding shaft rod 2 according to the shaft diameter of the roller installed on the roller beam 6 to be tested, and then adjust the detector to the corresponding standard length by setting the number of connecting rods 1 and extension rods 3 and the connection length according to the standard spatial length of the roller beam 6 to be tested. It can adapt to rollers of different shaft diameters and different lengths, thereby realizing the spatial length detection of different roller beams 6.

[0032] The above embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
