DETAILED DESCRIPTION

[0024] The content of the present invention will be described below with reference to specific embodiments.

[0025] Figure 1 is a schematic diagram of the structure of the detection stand of the present invention, Figure 2 This is the front view of the detection stand of the present invention. Figure 3 This is a left view of the detection stand of the present invention, as shown in Figure 1-3 As shown, the detection bench of the present invention includes: a frame structure 1, an auxiliary mechanism 2 fixed on the frame structure 1, a transfer mechanism 3 rotatably connected to the frame structure 1, and a support structure 4 fixed on the transfer mechanism 3.

[0026] The indexing mechanism 3 includes: a fixed seat 31 installed on the frame structure 1, an indexing wheel 32 rotatably connected to the fixed seat 31, a connecting rod 33 fixedly connected to the indexing wheel 32, and a reinforcement sleeve 34 fixed on the outer wall of the connecting rod 33 and located at an end away from the indexing wheel 32. Figure 6 The internal structure diagram of the indexing wheel is shown in Figure 2. Figure 1 and Figure 6 As shown, the fixing seat 31 includes two side plates 312 , and a first shaft 311 is fixed between the side plates 312 .

[0027] The indexing wheel 32 includes: a fixed wheel 321 detachably connected to the first shaft 311 , and a rotating wheel 322 detachably connected to the fixed wheel 321 . The rotating wheel 322 is located outside the fixed wheel 321 , and the outer wall of the rotating wheel 322 is connected to the connecting rod 33 .

[0028] In order to adapt to the multi-angle rollover detection, the device is provided with a transfer mechanism 3 to help flip the cab shell, and a support structure is provided to determine the connection point with the cab shell to support the cab shell. The frame structure 1 is used to support and transport the entire cab shell, and the auxiliary mechanism 2 is used to place the detection device. The specific principle of the device is as follows:

[0029] Place the cab shell on the support structure 4, stabilize the flipping point of the cab, and then use the front suspension assembly to stabilize the flipping axis of the cab shell, that is, the bottom position of the front end of the cab shell. Place the detection device on the auxiliary mechanism 2, and use the self-test device to send signals and data to the outside of the cab shell. Workers can directly receive and analyze the signals and data transmitted to the outside without drilling into the cab shell. After completing the detection of one angle, to change the angle detection, you only need to adjust the position of the index wheel 32 so that the rotating wheel 322 rotates to the appropriate detection position. During this process, the flipping point of the support structure 4 and the cab shell remains unchanged. The detection device then transmits the data and signals at this angle and compares them with the standard indicators.

[0030] This device uses a single connecting rod to locate the flipping point. Compared with the traditional support stand, this setting is very adaptable, and the interference caused by the rigid vibration under the mechanical connection is less. In the case of excluding manual detection, it is more conducive to the data intelligent detection of the flipping cab. While it is easy to turn, because the flipping structure occupies a small area, it is suitable for various types of cab bodies, especially on existing wide-head vehicles that need to replace specific sizes of support flipping devices. Since this device lacks a fixed flipping point and the original flipping axis form, this device is still universal for wide-head vehicle models and sizes.

[0031] Two layers are arranged inside the indexing wheel 32, so that the indexing wheel 32 can be installed on the first shaft 311, the inner layer is kept fixed, and the outer layer is rotated to control the indexing. This arrangement is more flexible and improves the rigidity of the inner fixed shaft, making the support and flipping of the connecting rod 33 more stable. The reinforcement sleeve 34 is also used to improve the rigidity of the rear half of the connecting rod 33 and expand the connection surface with the support structure 4 to ensure the stability of the support.

[0032] The outer wall of the first shaft 311 is provided with a plurality of indexing teeth 3111, and the inner wall of the fixed wheel 321 is provided with indexing grooves 3211 having the same number as the indexing teeth 3111, and the indexing grooves 3211 are matched with the indexing teeth 3111. When installing, the fixed wheel 321 can be inserted into the indexing teeth 3111 and the indexing grooves 3211, and this tooth-groove matching connection mode is not only stable but also easy to disassemble.

[0033] The outer wall of the fixed wheel 321 is provided with a plurality of positioning holes 3212, and the rotating wheel 322 is provided with a plurality of pin holes 3221. There is at least one pair of corresponding positions between the positioning holes 3212 and the pin holes 3221, and a pin shaft 35 is matched between the corresponding positioning holes 3212 and the pin holes 3221. Figure 6 In order to show another pair of corresponding holes, a pin shaft 35 is omitted and not shown. The position is fixed by the pin shaft 35, which is not only convenient for disassembly, but also can control the angle of rotation by the correspondence between different pin holes 3221 and positioning holes 3212. Since the detection only needs to select a few points for data detection, it is not necessary to detect the entire curved surface. Therefore, this setting here has met the detection requirements.

[0034] The pin holes 3221 and the positioning holes 3212 are all distributed in a circular array in the same semicircle. In this way, the angle required for the matching detection can be set, unnecessary drilling can be reduced, and the structural rigidity can be effectively improved, and the rotation stability of the rotating wheel 322 can be improved.

[0035] Figure 5 This is an enlarged view of the supporting structure, such as Figure 5 As shown, the support structure 4 is installed on the outside of the reinforcement sleeve 34, including: a connecting plate 41 detachably connected to the connecting rod 33, a support platform 42 fixed on the top of the connecting plate 41, a positioning rod 43 is fixed below the support platform 42, and the other end of the positioning rod 43 is installed on the reinforcement sleeve 34. The support structure 4 is mainly used to determine the point support, that is, the flipping point. The connecting plate 41 plays the role of connecting the support structure 4 and the connecting rod 33, and the support platform 42 is connected and fixed to the inner wall of the cab shell, and the fixing method can be bolt connection. The positioning rod 43 plays the role of supporting and positioning the support platform 42. When in use, since the area of ​​the support platform 42 is very small compared to the area of ​​the cab shell, it can be regarded as a point. When connecting, only a single bolt is used to fix it to determine the positional relationship between the support platform 42 and the shell.

[0036] Figure 7 for Figure 6 A partial view A, such as Figure 7 As shown, the indexing groove 3211 is a square groove, and the indexing teeth 3111 are round teeth. This arrangement ensures that the indexing teeth 3111 will not fill the indexing groove 3211, which is convenient for installation.

[0037] Figure 4 FIG. 1 is a top view of the detection stand of the present invention, as shown in FIG. Figure 1-4As shown, the rack structure 1 of the present invention comprises: a first rack 11, a plurality of columns 13 fixed on the top of the first rack 11, and a second rack 12 fixed on the top of the columns 13. A first base 121 and a second base 122 are fixed on the top of the second rack 12. A vertical pole 1211 is vertically fixed on the top of the first base 121, and the fixing seat 31 is installed on the top of the vertical pole 1211.

[0038] When in use, wheels can be installed at the bottom of the first frame 11 for easy transportation. The uprights 13 are used to raise the height of the frame structure to prevent the cab shell from touching the bottom. The second frame 12 is used to fix the transfer mechanism 3 and the auxiliary mechanism 2.

[0039] A support rod 1221 is fixed on the top of the second base 122, and the other end of the support rod 1221 is fixed to the vertical rod 1211. A plurality of ribs 111 are also provided on the first frame 11, and the other end of the ribs 111 is fixed to the side of the vertical column 13. The support rod 1221 and the ribs 111 are provided to strengthen the support and improve the structural stability.

[0040] The auxiliary mechanism 2 includes: a bottom frame 21 vertically and symmetrically fixed on both sides of the second frame 12, a pair of side frames 22 symmetrically fixed on the top of the bottom frame 21, and a crossbeam 23 connecting the side frames 22. A positioning rod 221 is provided on one side of the side frame 22, and a detector 2211 is fixed on the other end of the positioning rod 221. The bottom frame 21 is used for support, and the side frames 22 and the crossbeam 23 are used to place the detection device.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
