Description

Technical Field

[0001] The utility model relates to the technical field of tractor expansion platforms, in particular to a calibration tool for a sliding roller structure in a tractor expansion platform. Background Art

[0002] Aircraft cargo box lift truck is a vehicle used at airport aprons to load and unload containerized cargo in aircraft cargo holds. In order to improve the cargo transportation efficiency and loading capacity of the lift truck, an expansion platform needs to be designed.

[0003] In order to facilitate the adjustment of the position of the goods on the expansion platform, the expansion platform needs to be designed with a lifting structure. Figure 1 The existing lifting structure support includes a support frame 01, a support block 02 is welded at the bottom end of the support frame 01, a support inclined groove 021 is opened on the support block 02, and a plurality of mounting holes are opened on the side wall of the support inclined groove 021.

[0004] During the installation process, the entire support frame 01 is installed in conjunction with the support wheels installed on the expansion platform through the support chute 021. When lifting, the side walls of the support chute 021 will collide with the support wheels. In order to ensure that the goods remain stable when adjusting their positions, the support frame 01 needs to remain stable when lifting. Therefore, when manufacturing the support frame 01, it is necessary to ensure that the four support chute 021 dimensions are accurate and aligned. If the installation dimension error of one of the support chute 021 is large, the surface of the support frame 01 will be uneven when the entire support frame 01 is lifted, and there is a possibility of tipping over when the goods are moved.

[0005] When the staff are welding the support blocks, each staff member has a different welding method, resulting in different installation errors of the support bevels on each support frame. During inspection, the staff is required to install the support frame on the expansion platform and run it. Only through the running data can it be determined whether the installation dimensions of the support bevels are consistent. If the installation dimension error is large, the support frame needs to be disassembled and the installation dimension of the support block needs to be recalibrated. This prolongs the debugging time of the support frame and reduces the production efficiency of the expansion platform. Utility Model Content

[0006] In order to improve the debugging efficiency of the support frame, the present application provides a calibration tool for a sliding roller structure in a tractor expansion platform.

[0007] The present application provides a calibration tool for the sliding roller structure in the tractor expansion platform using the following technical solutions:

[0008] A calibration tool for a sliding roller structure in a tractor expansion platform comprises a calibration square tube and a calibration plate. The calibration plates are connected to both ends of the calibration square tube. The two calibration plates are arranged opposite to each other, and each calibration plate is provided with a plurality of calibration holes.

[0009] By adopting the above technical solution, when checking the support chute, the staff will fit the verification plate to the side wall of the support chute and push the verification square tube. If the verification square tube can smoothly enter the support chute, it means that the installation dimensions of the two support blocks at one end of the length direction of the support frame are consistent; if the verification square tube cannot smoothly enter the support chute, it means that the installation dimensions of the support blocks are inconsistent and need to be recalibrated. The staff uses the verification square tube and the verification plate to verify whether the dimensions of the two support chute are aligned. In this way, there is no need to install the support frame on the expansion platform for debugging, which omits the installation steps during the debugging of the support frame, shortens the debugging time of the support frame, and improves the debugging efficiency of the support frame, so as to improve the production efficiency of the expansion platform.

[0010] Optionally, a positioning groove matching the shape of the calibration square tube is formed on the calibration plate, and the calibration square tube is connected to the positioning groove.

[0011] By adopting the above technical solution, the positioning groove is used to limit the position of the calibration square tube on the calibration plate, and also limits the installation direction of the calibration plate, thereby improving the calibration accuracy of the calibration tool.

[0012] Optionally, a positioning side plate is provided on the verification plate, and the positioning side plate includes a limiting plate and a guide plate, the limiting plate is connected to the side wall of the verification plate, one end of the guide plate is connected to the limiting plate, the guide plate is inclined, and the two positioning side plates are arranged opposite to each other, from the limiting plate to the guide plate as a reference direction, the distance between the two positioning side plates gradually increases, and when verifying the support frame, the two support blocks are located between the two limiting plates.

[0013] By adopting the above technical solution, when checking the support chute, the staff often cannot make the check square tube flush with the width direction of the support frame, which will increase the check error of the check tool. During the check, the staff uses two guide plates to guide the check plate to smoothly fit the side wall of the support chute, and uses the limiting plate to limit the length direction of the check square tube, ensuring that during the check of the support chute, the check square tube is aligned with the width direction of the support frame, thereby reducing the check error of the check tool as much as possible.

[0014] Optionally, a side wall surface of the calibration plate away from the calibration square tube is coated with an anti-rust coating.

[0015] By adopting the above technical solution, the side wall of the calibration plate away from the calibration square tube is the calibration reference side wall. With long-term use, the surface of the side wall is prone to rust, which will increase the calibration error of the calibration tool. The staff uses anti-rust coating to protect the side wall, reducing the possibility of rust on the calibration plate and ensuring that the calibration tool maintains calibration accuracy for a long time.

[0016] Optionally, a reinforcing rib plate is connected inside the calibration square tube.

[0017] By adopting the above technical solution, the inside of the calibration square tube is hollow, and there is a possibility of deformation in the middle of the length direction of the calibration square tube, which will affect the calibration accuracy of the calibration tool. The staff improved the structural strength of the calibration square tube by reinforcing the rib plate, reduced the possibility of deformation of the calibration square tube, and further ensured the calibration accuracy of the calibration tool.

[0018] Optionally, a positioning bar is connected to the side wall of the verification square tube away from the verification plate, and the positioning bar is parallel to the length direction of the verification square tube.

[0019] By adopting the above technical solution, the positioning bar is used to limit the position of the verification plate in the supporting inclined slot, and is used to assist in verifying whether the mounting hole in the supporting inclined slot is aligned with the verification hole.

[0020] Optionally, an operating frame is connected to the calibration square tube, and the operating frame includes a support rod, a grip rod and a push rod, two of the support rods are connected on the side wall of the calibration square tube, the grip rod and the push rod are both connected between the two support rods, and the push rod is located between the grip rod and the calibration square tube.

[0021] By adopting the above technical solution, when checking the support bevel, the staff holds the grip to operate the verification tool to align the support block, and then pushes the push rod to make the verification tool smoothly enter the verification bevel, thereby improving the controllability of the verification tool. The push rod is used to assist the staff in applying force to the verification tool.

[0022] Optionally, the four corners of the calibration square tube are rounded.

[0023] By adopting the above technical solution, the four corners of the calibration square tube are rounded, which is used to reduce the stress concentration of the calibration square tube and the possibility of damage to the calibration square tube, and enables the calibration square tube to enter the supporting inclined groove more smoothly.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When checking the support chute, the staff will fit the verification plate to the side wall of the support chute and push the verification square tube. If the verification square tube can smoothly enter the support chute, it means that the installation dimensions of the two support blocks at one end of the length direction of the support frame are consistent; if the verification square tube cannot smoothly enter the support chute, it means that the installation dimensions of the support blocks are inconsistent and need to be recalibrated. The staff used the verification square tube and the verification plate to verify whether the dimensions of the two support chute were aligned. In this way, there is no need to install the support frame on the expansion platform for debugging, which omits the installation steps during the debugging of the support frame, shortens the debugging time of the support frame, and improves the debugging efficiency of the support frame, so as to improve the production efficiency of the expansion platform.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 2-4 This application is described in further detail.

[0032] The present application embodiment discloses a calibration tool for a sliding roller structure in a tractor expansion platform. Figure 2 The calibration tool for the sliding roller structure in the tractor expansion platform includes a calibration square tube 1 and a calibration plate 2. The calibration square tube 1 is hollow, and the four corners of the calibration square tube 1 are rounded. The rounded corners of the calibration square tube 1 are used to facilitate the calibration square tube 1 to smoothly enter the support inclined groove 021. A reinforcing rib plate 11 is welded inside the calibration square tube 1, and the reinforcing rib plate 11 is used to improve the structural strength of the calibration square tube 1.

[0033] Reference Figure 2 An operating frame 3 is provided on the side wall of the calibration square tube 1, and the operating frame 3 includes a support rod 31, a grip rod 32 and a push rod 33. Two support rods 31 are connected on the side wall of the calibration square tube 1 by bolts, and the grip rod 32 and the push rod 33 are fixedly connected between the two support rods 31. The grip rod 32 and the push rod 33 are parallel to the calibration square tube 1, and the push rod 33 is located between the grip rod 32 and the calibration square tube 1. A rubber pad is sleeved on the grip rod 32.

[0034] Reference Figure 3The check plate 2 is a rectangular plate, and one check plate 2 is provided at both ends of the length direction of the check square tube 1. A positioning groove 21 matching the shape of the check square tube 1 is provided on the surface of the check plate 2, and the check square tube 1 is welded in the positioning groove 21. The positioning groove 21 is used to limit the installation direction of the check plate 2. A plurality of check holes 22 are provided on the surface of the check plate 2. Two are taken as an example in this embodiment, and the check square tube 1 is located between the two check holes 22.

[0035] Reference Figure 2 , a positioning side plate 4 is provided on the check plate 2, and the positioning side plate 4 includes a limiting plate 41 and a guide plate 42. The limiting plate 41 is connected to the side of the check plate 2 by bolts, and one end of the guide plate 42 is fixedly connected to one end of the limiting plate 41. The guide plate 42 is arranged obliquely, and the two positioning side plates 4 are arranged opposite to each other. With the limiting plate 41 to the guide plate 42 as the reference direction, the distance between the two positioning side plates 4 gradually increases. The limiting plate 41 is used to limit the length direction of the check square tube 1, and the guide plate 42 is used to assist in guiding the support block 02 to enter between the two limiting plates 41.

[0036] Reference Figure 4 When checking the support block 02, the staff holds the grip 32 and moves the checking tool so that the two support blocks 02 are located between the two positioning side plates 4, and the side wall of the checking plate 2 fits the side wall of the supporting inclined groove 021. Then, the push rod 33 is pushed, and while the checking plate 2 moves, the limiting plate 41 fits the side wall of the support block 02 until the checking square tube 1 enters the supporting inclined groove 021. If the supporting and checking square tube 1 enters the two supporting inclined grooves 021 at the same time, it means that the installation dimensions of the two support blocks 02 are consistent. If the checking square tube 1 cannot enter the two supporting inclined grooves 021 at the same time, it means that the installation dimensions of the two support blocks 02 are inconsistent, and the support blocks 02 need to be recalibrated.

[0037] Reference Figure 2 In order to better calibrate the mounting holes in the support inclined groove 021, a positioning bar 12 is fixedly connected to the side wall of the calibration square tube 1 away from the calibration plate 2, and the positioning bar 12 is parallel to the length direction of the positioning square tube.

[0038] When the calibration square tube 1 enters the supporting inclined groove 021, the positioning strip 12 contacts the edge of the supporting inclined groove 021. At this time, the calibration hole 22 is observed. At this time, a latch can be inserted into the calibration hole 22 to check whether the latch can enter the mounting hole, so as to determine whether the mounting hole position is accurate.

[0039] Reference Figure 2 and Figure 4In order to ensure that the calibration tool can maintain the calibration accuracy for a long time, the side wall surface of the calibration plate 2 away from the calibration square tube 1 is coated with an anti-rust coating. The anti-rust coating in this embodiment is a polytetrafluoroethylene coating. The polytetrafluoroethylene coating can reduce the possibility of rust on the calibration plate 2 and reduce the friction of the side wall of the calibration plate 2, so that the calibration plate 2 moves more smoothly in the supporting inclined groove 021.

[0040] The implementation principle of a calibration tool for a sliding roller structure in a tractor expansion platform according to an embodiment of the present application is as follows: when calibrating the support block 02, the staff holds the grip 32 to make the calibration plate 2 fit the side wall of the support inclined groove 021, and uses the limiting plate 41 to calibrate the length direction of the calibration square tube 1, and then pushes the push rod 33 to move the calibration plate 2. If the calibration square tube 1 successfully enters the support inclined groove 021, it indicates that the installation dimensions of the two support blocks 02 are consistent, until the positioning bar 12 contacts the edge of the support inclined groove 021. At this time, a pin is inserted into the calibration hole 22 to check whether the pin can be inserted into the installation hole to check whether the position of the installation hole is accurate; if the calibration square tube 1 cannot smoothly enter the support inclined groove 021, it indicates that the installation dimensions of the two support blocks 02 are inconsistent and need to be re-debugged.

[0041] The staff used the verification square tube 1 and the verification plate 2 to verify whether the sizes of the two supporting bevel grooves 021 were aligned. In this way, there was no need to install the support frame 01 on the expansion platform for debugging, which omitted the installation steps during the debugging of the support frame 01, shortened the debugging time of the support frame 01, and improved the debugging efficiency of the support frame 01, thereby improving the production efficiency of the expansion platform.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
