Description

Technical Field

[0001] This utility model relates to the field of carriage alignment technology, and in particular to a carriage alignment device with a telescopic support mechanism. Background Technology

[0002] With the rapid development of the logistics and transportation industry, detachable trucks are widely used in container transportation, emergency material allocation, and other fields due to their advantages of flexible loading and unloading and rapid transfer. These trucks typically have hydraulic or mechanical support legs at the four corners of the cargo box, which are raised and lowered to separate or assemble the cargo box from the chassis frame. Before assembling the cargo box and the truck frame, they need to be aligned. After the docking process is completed, a straightening device is needed to adjust the position of the cargo box. During the straightening process, the straightening device is subjected to significant pressure, which can easily cause it to shake and affect the accuracy of the straightening.

[0003] A positioning and correction buffer device for a detachable vehicle is disclosed in Chinese patent document CN222062125U. This positioning and correction buffer device for a detachable vehicle includes a fixing device for positioning and fastening the frame in the front-rear direction between the lower frame and the upper frame, an upper and lower positioning device, and / or a left and right correction buffer device. The upper and lower positioning device includes an upper positioning frame and a lower positioning frame. The lower positioning frame includes a bottom reinforcing plate of the lower frame and two bent plates. The upper positioning frame and the two bent plates are connected by a pin and positioned and fixed in the pin hole. The left and right correction buffer device includes an upper slide and a lower slide. The lower rolling element of the upper slide is rotatably connected to the upper inclined plate and the side inclined plate of the lower slide. The inner inclined plate and the lower inclined plate of the upper slide are rotatably connected to the upper rolling element of the lower slide. In this utility model device, the purpose of precise positioning and buffer positioning during the fixing, positioning and left and right correction processes is achieved by fixing device, upper and lower positioning device and left and right correction buffer device respectively. However, the buffer of this positioning correction buffer device for detachable vehicles relies on itself, which requires a high degree of firmness of the installation part.

[0004] To address the shortcomings of the existing technology, providing a carriage correction device with a telescopic support mechanism is a problem worthy of research. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the correction device being subjected to large pressure during the correction process, which makes it prone to shaking and affects the accuracy of correction. It provides a carriage correction device with a telescopic support mechanism, which achieves the technical effect of auxiliary support for the correction device.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A carriage correction device with telescopic support mechanism includes a frame and a carriage assembled and connected to the frame, as well as two correction mechanisms on each of the left and right sides of the frame, and an auxiliary support mechanism at the bottom of the correction mechanism.

[0008] The auxiliary support mechanism includes a hydraulic telescopic cylinder fixedly connected to the bottom of the correction mechanism;

[0009] When the hydraulic telescopic cylinder is extended, its bottom height is equal to the bottom height of the transport vehicle's wheels. By setting the hydraulic telescopic cylinder at the bottom of the correction mechanism, when loading and docking the cargo compartment, the hydraulic telescopic cylinder is extended and supported on the ground, which can play a certain auxiliary support role for the correction mechanism, help bear the large force generated during the correction of the cargo compartment, improve the stability of the correction mechanism, and improve the correction accuracy of the correction mechanism.

[0010] The hydraulic telescopic cylinder has two control buttons on its side. By setting two control buttons on the hydraulic telescopic cylinder, the extension and retraction of each hydraulic telescopic cylinder can be controlled individually, so that it can support on uneven road surfaces. At the same time, the four hydraulic telescopic cylinders are connected to a PLC controller, which can control them synchronously and provide rapid support on flat road surfaces.

[0011] The correction mechanism includes a correction frame fixedly connected to the vehicle frame and correction wheels rotatably connected to the bottom of the vehicle body;

[0012] The positions and numbers of the correction frames and correction wheels correspond one-to-one. The inner side of the top of the correction frame is a slope. By setting the correction frames and correction wheels on the frame and the carriage respectively, when the carriage is docked and installed, the correction wheels first contact the correction frames, and under the action of the slope, they correct the left and right deviations, so that the two are accurately docked.

[0013] The correction mechanism also includes a second telescopic cylinder fixedly connected to the middle of the correction frame. The output end of the second telescopic cylinder faces upward. By setting the second telescopic cylinder in the middle of the correction frame, when docking the carriages, the second telescopic cylinder is raised to a certain height so that it cooperates with the inclined surface at the top of the correction frame to form a larger correction inclined surface, further expanding the correction range and avoiding the situation where the carriage deviation is too large to be corrected.

[0014] The correction mechanism also includes a limiting frame rotatably connected to the top of the correction frame, a limiting block disposed above the limiting frame, a locking block rotatably connected to the limiting block, a threaded knob threadedly connected to the locking block, and a locking frame disposed at the bottom of the carriage.

[0015] The bottom of the locking frame has a slot, the shape of which is adapted to the shape of the locking block.

[0016] A limiting angle iron is fixedly connected to the front side of the top of the frame. The included angle of the limiting angle iron is rounded. By setting the limiting angle iron, the front and rear positions of the carriages can be adjusted when they are docked.

[0017] Positive and beneficial effects:

[0018] 1. The carriage correction device with telescopic support mechanism, by setting a hydraulic telescopic cylinder at the bottom of the correction mechanism, extends the hydraulic telescopic cylinder to support it on the ground when loading and docking the carriage, which can play a certain auxiliary support role for the correction mechanism, help to bear the large force generated during the carriage correction process, improve the stability of the correction mechanism, and improve the correction accuracy of the correction mechanism.

[0019] 2. The carriage alignment device with telescopic support mechanism sets alignment frames and alignment wheels on the frame and carriage respectively. When the carriage is installed, the alignment wheels first contact the alignment frames and then perform left and right alignment under the action of the inclined plane, so that the two are accurately aligned.

[0020] 3. The car body alignment device with telescopic support mechanism, by setting a locking component on the outside of the alignment frame, after the docking of the car frame and the car body is completed, the limiting block and the locking block are lifted up, and the locking block is inserted into the locking frame from the slot. The locking block is then rotated 90 degrees to fix it in the locking frame. At the same time, the limiting frame is rotated to make the locking block enter the groove of the limiting frame to complete the angle limitation. Finally, the threaded knob is rotated to further lock the locking block, thereby realizing the locking engagement between the locking block and the locking frame, so that the car frame and the car body are assembled and fixedly connected, improving the stability of the car body during transportation.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0031] like Figures 1 to 8 As shown, a carriage correction device with a telescopic support mechanism includes a frame 1 and a carriage 2 assembled and connected to the frame 1. The device is characterized in that it further includes two correction mechanisms on each of the left and right sides of the frame 1, and an auxiliary support mechanism at the bottom of the correction mechanism.

[0032] like Figures 1 to 3 As shown, the auxiliary support mechanism includes a hydraulic telescopic cylinder 3 that is fixedly connected to the bottom of the correction mechanism;

[0033] When the hydraulic telescopic cylinder 3 is extended, its bottom height is equal to the bottom height of the transport vehicle's wheels. By setting the hydraulic telescopic cylinder 3 at the bottom of the correction mechanism, when loading and docking the cargo box, the hydraulic telescopic cylinder 3 is extended and supported on the ground, which can play a certain auxiliary support role for the correction mechanism, help bear the large force generated during the correction of the cargo box, improve the stability of the correction mechanism, improve the correction accuracy of the correction mechanism, and at the same time avoid the correction mechanism from loosening and falling off due to long-term bearing of large forces. In addition, the hydraulic telescopic cylinder 3 can extend and extend independently, and provide adaptive support according to the flatness of the road surface, adapting to uneven road surfaces.

[0034] Furthermore, the hydraulic telescopic cylinder 3 is replaced with an electric telescopic cylinder, which is smaller in size and easier to install and maintain.

[0035] like Figures 1 to 3As shown, two control buttons 4 are provided on the side of the hydraulic telescopic cylinder 3. By setting two control buttons 4 on the hydraulic telescopic cylinder 3, the extension and retraction of each hydraulic telescopic cylinder 3 can be controlled individually, so that it can support on uneven road surfaces. At the same time, the four hydraulic telescopic cylinders 3 are connected to the PLC controller, which can control them synchronously and provide rapid support on flat road surfaces. Example 2

[0036] like Figures 1 to 8 As shown, the correction mechanism includes a correction frame 5 fixedly connected to the frame 1, and a correction wheel 6 rotatably connected to the bottom of the carriage 2;

[0037] The positions and numbers of the straightening frame 5 and the straightening wheel 6 correspond one-to-one. The inner side of the top of the straightening frame 5 is a slope. By setting the straightening frame 5 and the straightening wheel 6 on the frame 1 and the carriage 2 respectively, when the carriage 2 is docked and installed, the straightening wheel 6 first contacts the straightening frame 5 and performs left and right correction under the action of the slope, so that the two are accurately docked.

[0038] like Figures 1 to 3 As shown, the correction mechanism also includes a second telescopic cylinder 7 fixedly connected to the middle of the correction frame 5. The output end of the second telescopic cylinder 7 faces upward. By setting the second telescopic cylinder 7 in the middle of the correction frame 5, when docking the carriages, the second telescopic cylinder 7 is raised to a certain height so that it cooperates with the inclined surface at the top of the correction frame 5 to form a larger range of correction inclined surface, further expanding the correction range and avoiding the situation where the carriage deviation is too large to be corrected. Example 3

[0039] like Figure 2 and Figure 3 As shown, the correction mechanism also includes a limiting frame 8 rotatably connected to the top of the correction frame 5, a limiting block 9 disposed above the limiting frame 8, a locking block 10 rotatably connected to the limiting block 9, a threaded knob 11 threadedly connected to the locking block 10, and a locking frame 12 disposed at the bottom of the carriage 2.

[0040] The bottom of the locking frame 12 has a slot, the shape of which matches the shape of the locking block 10. By setting a locking component on the outside of the correction frame 5, after the docking of the frame 1 and the carriage 2 is completed, the limiting block 9 and the locking block 10 are lifted up. After the locking block 10 enters the locking frame 12 from the slot, the locking block 10 is rotated 90 degrees to fix it in the locking frame 12. At the same time, the limiting frame 8 is rotated to make the locking block 10 enter the groove of the limiting frame 8 to complete the angle limitation. Finally, the threaded knob 11 is rotated to further lock the locking block 10, so that the locking block 10 and the locking frame 12 can be locked together, and the frame 1 and the carriage 2 can be assembled and fixedly connected, improving the stability of the carriage during transportation.

[0041] like Figures 6 to 8As shown, a limiting angle iron 13 is fixedly connected to the front side of the top of the frame 1. The limiting angle iron 13 has a rounded corner at the included angle. By setting the limiting angle iron 13, the front and rear positions of the carriage 2 can be adjusted when docking.

[0042] The working principle of this utility model is as follows:

[0043] S1. When loading and docking the carriages, the hydraulic telescopic cylinder 3 is extended and supported on the ground, which can play a certain auxiliary support role for the correction mechanism and help bear the large force generated during the correction of the carriages.

[0044] S2. When installing the carriage 2, the straightening wheel 6 first contacts the straightening frame 5 and performs left and right straightening under the action of the inclined plane, so that the two are accurately connected.

[0045] S3. When docking the carriages, raise the second telescopic cylinder 7 to a certain height so that it can cooperate with the inclined surface at the top of the correction frame 5 to form a larger correction inclined surface and further expand the correction range.

[0046] S4. After completing the docking of the frame 1 and the carriage 2, lift up the limiting block 9 and the locking block 10, and after the locking block 10 enters the locking frame 12 from the slot, rotate the locking block 10 ninety degrees to fix it in the locking frame 12. At the same time, rotate the limiting frame 8 to make the locking block 10 enter the groove of the limiting frame 8 to complete the angle limitation. Finally, rotate the threaded knob 11 to further lock the locking block 10, so as to realize the locking engagement between the locking block 10 and the locking frame 12.

[0047] S5 and limiting angle iron 13 adjust the front and rear positions of the carriages 2 during docking.

[0048] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
