[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.
[0021] As shown in the figure, the present utility model discloses a lifting part set for a grid structure laying machine, which includes an upper pressing frame 1. One end of the upper pressing frame 1 is connected to the upper ends of two first guide wheel mounting plates 3 through a connecting pin 2. In this way, the upper pressing frame 1 can rotate relative to the first guide wheel mounting plate 3.
[0022] One first guide wheel 4 is installed between two first guide wheel mounting plates 3. Specifically, the first guide wheel 4 is installed on a first guide wheel mounting shaft 5. Both ends of the first guide wheel mounting shaft 5 are respectively installed on the first guide wheel mounting plates 3. The bottom of the first guide wheel mounting plate 3 is installed on one side of the top of a first support block 6. Two second guide wheel mounting plates 7 are also installed on the top of the first support block 6. One first guide wheel 4 is installed between the two second guide wheel mounting plates 7.
[0023] The present utility model is mainly used for the two-end support during the laying of large molds. This structure is different from the conventional center frame. The conventional center frame cannot move forward and backward and can only be fixed at a certain position. However, the present utility model is mainly fixed at both ends of the headstock and the tailstock to maintain the equipment stability and reliability during the laying of the mold. It moves forward and backward within a certain stroke through the lower lifting speed reducer. After moving to the corresponding position, the brake block is locked. At this time, the mold starts to be laid. The support plate 10 is connected to the ram. The design of the first guide wheel enables the adjustment of the shaft diameters at both ends of the mold within a certain range, which can increase the laying range of the mold. The lifting cover plate mainly presses the ram to prevent it from moving in any direction. The upper pressing frame 1 at the upper end is for the convenience of mold clamping. It can be flexibly opened and locked after installation to ensure its normal operation.
[0024] Two guide wheels are installed with a limit block one 8 at the top of the mounting plate two 7. A limit groove 81 is provided in the middle of the outer side of the limit block one 8. The lower end of the support block one 6 is installed on the ram 9. The upper end of the ram 9 passes through the support plate 10. The lower ends of both ends of the support plate 10 are connected to the slider 11. The sliders 11 are respectively connected to the guide rails 12. The lower ends of the guide rails 12 are installed on the guide rail mounting plate 13. The guide rail mounting plate 13 is installed on the support frame 14. The support frame 14 is installed on the rear plate 16 of the tailstock 15. Before placing the shaft, first open the upper pressing frame 1, then place the shaft, and then rotate the upper pressing frame 1 to cover the shaft. The lower end of the shaft is located on the two guide wheels one 4.
[0025] The slider 11 can move along the guide rail 12, driving the upper pressing frame 1, the guide wheel mounting plate one 3 and the support block one 6 to move, facilitating the holding of the shaft.
[0026] In an embodiment of the present utility model, a rotating shaft 17 is provided in the middle of the other end of the upper pressing frame 1. The top of the rotating shaft is connected to the upper pressing frame 1 through a connecting pin. The diameter of the rotating shaft 17 is smaller than the width of the limit groove 81. A nut 18 is installed at the lower end of the rotating shaft 17. Here, the rotating shaft 17 is rotated to the limit groove 81, and then the nut 18 is used to lock the rotating shaft 17 to prevent the rotating shaft 17 from shaking.
[0027] In an embodiment of the present utility model, the support frame 14 includes two support bottom plates 141, a support front plate 142 and a support rear plate 143. The two support bottom plates 141 connect the support front plate 142 and the support rear plate 143. The guide rail mounting plate 13 is respectively installed on the support bottom plates 141. The support rear plate 143 is installed on the rear plate 16 of the tailstock. The design of the support frame 14 enables it to be installed on the side of the tailstock and does not need to be installed on the ground, greatly reducing the floor area and at the same time reducing the equipment size.
[0028] In an embodiment of the present utility model, a lifting cover plate 23 is provided at the front end of the support plate 10. A lower fixing plate is provided at the lower side of the rear end of the support plate 10. A flange 24 is installed at the lower parts of the lifting cover plate 23 and the lower fixing plate. Bearing mounting plates are installed on both sides of the flange 24. A rack is provided at the bottom of the ram 9. A lifting reduction gear 25 engaged with the lower end of the rack is provided. Teeth are provided on the outer surface of the lifting reduction gear 25. The lifting reduction gear 25 is connected to the drive shaft 26. The two ends of the drive shaft 26 are respectively connected to the hand wheels 27. The two sides of the drive shaft 26 are installed on bearings, and the bearings are installed on the bearing mounting plates. The ram 9 can only vertically lift relative to the support plate 10. Manually rotate the hand wheel 27 to drive the drive shaft 26 to rotate, and finally drive the lifting reduction gear 25 to rotate. The top of the lifting reduction gear 25 changes, similar to the design of a cam, thereby driving the ram 9 to lift and lower.
[0029] In an embodiment of the present utility model, the length of the support rear plate 143 is greater than that of the support front plate 142. A groove 1411 is provided at the front end of the support bottom plate 141, and the handwheel 27 is located outside the support bottom plate 141.
[0030] In an embodiment of the present utility model, locking plates 19 are installed at the rear ends of the two guide rails 12. The locking plates 19 are locked by a locking handle 28. By means of the locking handle 28, the position of the locking plates 19 can be adjusted. A brake connection plate 20 is installed between the two locking plates 19. Two limit screws 21 are installed on the guide rail mounting plate 13. The slider 11 is located between the two limit screws 21, and the limit screws 21 are located outside both ends of the guide rail 12.
[0031] In an embodiment of the present utility model, a second guide wheel mounting hole 101 is installed at the middle of the upper end of the upper pressing frame 1. The second guide wheel 22 is installed at the second guide wheel mounting hole 101. The tops of the two first guide wheels 4 are flush. The second guide wheel 22 is located above the two first guide wheels 4. The connecting line of the axes of the first guide wheel 22 and the second guide wheel 22 is an isosceles triangle. The first guide wheel 4 is used to limit the top of the shaft.
[0032] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
