Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a detachable assembly trolley base adjustment device. Background Technology

[0002] In the precast beam yard, the trolleys used for transporting and assembling precast beams require precise underframe adjustment. The separate assembly trolley underframe adjustment device can ensure that the underframe remains stable and level under different working conditions, such as when the trolley is loaded with precast beams of different weights or when it is traveling on tracks with different slopes, thus ensuring the safe and accurate transportation and assembly of precast beams.

[0003] In the existing technology, some of the separate assembly trolley chassis adjustment devices achieve precise adjustment through hydraulic or mechanical transmission. The device consists of multiple independently controllable adjustment units, each equipped with a hydraulic cylinder or screw mechanism. When it is necessary to adjust the height, level, or angle of the chassis, the control system issues a command to drive the corresponding adjustment unit to act.

[0004] However, in actual use, when the length of the base frame cannot be adjusted as a whole, during the assembly of the trolley, different construction needs may require adjustments in other complex ways, such as replacing parts of different lengths or making multiple local adjustments. This increases the difficulty and time cost of assembly. In response to the above problems, a separate assembly trolley base frame adjustment device is proposed. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a detachable assembly trolley base adjustment device, including a mounting shell 1. The inner wall of the mounting shell 1 has been finely processed to reduce frictional resistance during component movement. At the same time, the surface of the mounting shell 1 has undergone anti-corrosion treatment, such as electrostatic spraying of anti-corrosion paint, to improve its corrosion resistance under different working environments. An adjustment mechanism is fixedly connected inside the mounting shell 1. Adjustment plates 12 are fixedly connected to the left and right sides of the adjustment mechanism. The function of the adjustment plates 12 is to transmit the movement of the adjustment mechanism to the support slider 15 to realize the adjustment of the trolley base. To ensure the flexibility and accuracy of adjustment, the surface of the adjustment plate 12 has been flattened. Fixed rods 13 are fixedly connected to the front and rear sides of the top of the adjustment plate 12. The surface of the fixed rods 13 has been quenched and tempered to improve its wear resistance and deformation resistance. Tension springs 14 are sleeved on the outside of the fixed rods 13. The function of the tension springs 14 is to provide buffering and reset when the support slider 15 moves, so as to ensure the smoothness of the adjustment process. The support slider 15 is slidably connected to the outside of the fixed rods 13. The support slider 15 is cuboid in shape, and its size is designed according to the size of the fixed rods 13 and the adjustment plate 12. A hydraulic cylinder 19 is fixedly connected to the top of the support slider 15.

[0035] The working pressure of hydraulic cylinder 19 is provided by a hydraulic pump station, which can generate a large thrust for adjusting the height of the trolley base. A clamping mechanism is fixedly connected to the top of the support slider 15. The clamping mechanism includes a motor 21. The power of the motor 21 is selected according to the actual working requirements of the clamping mechanism. The motor 21 can adapt to different working environments. The outer bottom end of the motor 21 is fixedly connected to the top of the support slider 15. A drive shaft 22 is fixedly connected to the drive end of the motor 21. The surface of the drive shaft 22 has been ground to ensure its connection accuracy with the coupling and drive plate 23. The drive plate 23 is fixedly connected to the outside of the drive shaft 22. Its size is determined according to the movement range of the follower plate 24 and the clamping force requirements. The drive plate 23 is rotatably connected to both its front and rear sides. The follower plate 24 is elongated, and its length and width are designed according to the dimensions of the drive plate 23 and the sliding plate 26. A fixed shaft 25 is fixedly connected to the top of the follower plate 24, and a sliding plate 26 is fixedly connected to the outside of the fixed shaft 25. The sliding plate 26 is made of high-strength steel plate and is rectangular. Its dimensions are designed according to the dimensions of the fixed shaft 25 and the clamping plate 27. A clamping plate 27 is fixedly connected to the top of the sliding plate 26. The shape of the clamping plate 27 is designed according to the shape and dimensions of the trolley base frame, which can tightly clamp the trolley base frame and ensure its stability during the adjustment process.

[0036] The adjustment mechanism includes a mounting spring 2. The elastic coefficient of the mounting spring 2 is precisely calculated to provide appropriate elastic force according to the adjustment requirements, ensuring the smoothness and accuracy of the adjustment. The mounting spring 2 is located inside the mounting shell 1. Multiple limiting blocks 3 are slidably connected inside the mounting shell 1. The function of the limiting blocks 3 is to limit the movement range of the adjustment plate 12, ensuring that the adjustment process is carried out within a safe and reliable range. A docking plate 4 is fixedly connected to the outside of the limiting blocks 3. The function of the docking plate 4 is to transmit the movement of the limiting blocks 3 to the adjustment plate 12, thereby realizing the synchronous movement of the adjustment plate 12. The docking plate 4 is fixedly connected to the outside of two adjustment plates 12 on the adjacent side. Clamping components are fixedly connected to the four corners of the outside of the mounting shell 1. The clamping components include mounting brackets 5. The dimensions of the mounting brackets 5 are designed according to the installation requirements of the rotating clamping plate 7. The mounting bracket 5 is fixedly connected to the four corners of the outer side of the mounting shell 1. The mounting bracket 5 is fixedly connected to the inner side of the connecting shaft 6. The surface of the connecting shaft 6 is ground to ensure that the rotating clamp 7 can rotate flexibly on it. The external side of the connecting shaft 6 is rotatably connected to the rotating clamp 7. The function of the rotating clamp 7 is to achieve the clamping and loosening operation of the trolley base frame by rotating. One end of the rotating clamp 7 is fixedly connected to the telescopic rod 8. The telescopic rod 8 is composed of an inner rod and an outer tube. The inner rod can freely extend and retract within the outer tube. The external side of the telescopic rod 8 is fitted with a return spring 9. The function of the return spring 9 is to provide the return elastic force after the rotating clamp 7 rotates, so that the rotating clamp 7 can return to the initial position. The other end of the rotating clamp 7 is fixedly connected to the clamp rod 10. The function of the clamp rod 10 is to clamp the trolley base frame when the rotating clamp 7 rotates to the appropriate position, so as to ensure the stability of the trolley base frame during the adjustment process.

[0037] Reference Figures 3 to 5The front and rear sides of the connecting plate 4 are provided with slots 11. The outer side of the locking rod 10 is locked with the outer side of the slot 11, and the locking rod 10 is precisely embedded in the slot 11. The mechanical locking ensures that the adjusting plate 12 remains fixed after adjustment. The front and rear sides of the adjusting plate 12 are slidably connected with sliding locking rods 16. One end of the sliding locking rod 16 is machined with external threads for fixing with the limiting plate 17; the other end is hemispherical to facilitate insertion into the locking hole of the supporting slider 15. The sliding locking rod 16 and the adjusting plate 12 are slidably connected through a linear bearing to ensure that they can move flexibly during adjustment while maintaining good guidance. The outer side of the sliding locking rod 16 is fixedly connected to the limiting plate 17. The limiting plate 17 is fastened to the threaded end of the sliding locking rod 16 with a nut to prevent the sliding locking rod 16 from coming out of the adjusting plate 12. A fixing spring 18 is sleeved on the outer side of the adjusting plate 12. When the position of the support slider 15 needs to be adjusted, the external force overcomes the spring force and causes the sliding rod 16 to retract, releasing the clamping state. The outside of the sliding rod 16 is clamped to the outside of the support slider 15. Hydraulic cylinders 19 are fixedly connected to the top front and rear sides of the support slider 15. The working pressure of the hydraulic cylinders 19 is provided by the hydraulic pump station, which can accurately control the lifting and lowering of the fixed platform 20. The outside of the support slider 15 is slidably connected to the top of the adjustment plate 12. The drive end of the hydraulic cylinder 19 is fixedly connected to the fixed platform 20. The surface of the fixed platform 20 is milled to ensure that the motor 21 remains horizontal after installation, avoiding unstable operation due to tilting. The bottom of the fixed platform 20 is fixedly connected to the top of the motor 21. One end of the spring 2 is fixedly connected to the outside of the right limit block 3, and the other end of the spring 2 is fixedly connected to the outside of the left limit block 3.

[0038] Working principle: When adjusting the overall length, by pressing the rotating plates 7 on the front and rear sides of the outer side of the mounting shell 1, the rotating plates 7 can squeeze the return spring 9, which in turn can cause the rotating plates 7 to drive the locking rod 10 to separate from the locking groove 11 on the outside of the docking plate 4. Then, by pressing the adjusting plate 12, the adjusting plate 12 can drive the docking plate 4 to squeeze the mounting spring 2 inside the mounting shell 1. When the appropriate position is reached, by releasing the rotating plates 7, the telescopic rod 8 rebounds, which allows the rotating plates 7 to lock into the locking groove 11 on the outside of the docking plate 4 through the locking rod 10, thereby adjusting the overall length.

[0039] When adjusting the support slider 15, by pulling the sliding lever 16, the sliding lever 16 is pressed against the fixed spring 18 through the limiting plate 17, thereby separating the outside of the sliding lever 16 from the support slider 15. By pulling the support slider 15, the support slider 15 can press against the tension spring 14. When the support slider 15 is adjusted to a suitable position, by releasing the sliding lever 16, the fixed spring 18 rebounds, thereby locking the sliding lever 16 and the support slider 15 together.

[0040] By starting the motor 21, the motor 21 drives the drive shaft 22 to rotate, which in turn drives the drive plate 23 to rotate. The drive plate 23 then drives the follower plate 24 to rotate, which in turn drives the follower plate 24 to rotate via the fixed shaft 25. This allows the follower plate 24 to slide the sliding plate 26 outside the fixed platform 20, thereby enabling the two clamping plates 27 to clamp and fix the items to be inspected.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
