Description

TECHNICAL FIELD

[0001] The present application belongs to the field of concrete steam curing equipment, and more particularly to a steam curing frame and steam curing bottom plate supporting rod pulling-out equipment. BACKGROUND

[0002] In the existing autoclaved aerated concrete block and board flat steaming process production line, the placement of the autoclaved aerated concrete autoclaving frame or autoclaving bottom plate selectively uses vertical autoclave or flat autoclave according to the shape of the blank. When flat autoclave is used, multiple steam curing frames or steam curing bottom plates need to be stacked, so positioning and supporting need to be performed between the upper and lower steam curing frames or steam curing bottom plates during stacking, and the rod needs to be pulled out after steam curing to complete disassembly. Figure 6 and 7 As shown, the supporting rod is a rod-shaped structure, and the upper and lower ends each have a larger diameter boss. When the steam curing frame or steam curing bottom plate is stacked, the supporting rod is inserted into the through hole of the lower steam curing frame or steam curing bottom plate, so that the lower surface of the lower end boss abuts against the upper surface of the through hole. Then, the through hole of the upper steam curing frame or steam curing bottom plate is sleeved on the upper end of the supporting rod, so that the lower surface of the through hole of the upper steam curing frame or steam curing bottom plate abuts against the upper surface of the upper end boss, achieving the support and separation of the multiple layers of steam curing frames or steam curing bottom plates.

[0003] In the conventional equipment, the supporting rod is generally clamped by a cylinder or other clamping device during pulling out. Since the supporting rod is theoretically arranged in the height direction, the clamping device is generally adjusted to correspond to the height direction. However, in actual operation, it is found that due to the fact that the structure of the supporting rod itself cannot be completely uniform, movement and deviation occur during production, and the steam curing frame or steam curing bottom plate deforms, etc., the center axis of the supporting rod clamped by the clamping jaw and the center axis of the hole into which the supporting rod is inserted often do not coincide during clamping of the supporting rod, resulting in the phenomenon that the supporting rod is difficult to pull out.

[0004] As the applicant once applied for the patent literature with the Chinese patent application number CN202210421224.4 and the publication date of September 2, 2022, a steam curing bottom plate supporting rod dismounting equipment is disclosed, which relates to the technical field of autoclaved aerated concrete block production. The invention comprises a horizontal moving mechanism movably installed on a left-right symmetrical arrangement of a ground beam assembly, a vertical moving mechanism is provided on the inner side of the horizontal moving mechanism, a clamping mechanism is symmetrically provided on the inner side of the vertical moving mechanism through an extension mechanism, a rotary drive mechanism is provided at the tail end of the clamping mechanism to drive the clamping mechanism and the supporting rod clamped thereon to realize various movements in space to meet the dismounting requirements of the supporting rods at various positions on the steam curing bottom plate; the clamping mechanism comprises a clamping seat, a guide rod is provided on the outer side of the clamping seat, a clamping plate I and a clamping plate II are coaxially sleeved thereon, and a pressing mechanism I and a pressing mechanism II are symmetrically provided on the outer sides of the two, respectively, the two can be pressed simultaneously or individually to dynamically adapt to the offset of the supporting rod, and precise grabbing and placing can be realized.

[0005] The scheme is to dismount the supporting rod by clamping the supporting rod. However, as mentioned earlier, the center axis of the supporting rod clamped by the clamping jaw and the center axis of the hole into which the supporting rod is inserted do not coincide, resulting in the phenomenon that the supporting rod is difficult to pull out.

[0042] Embodiment 1

[0043] A kind of steaming frame and steaming bottom plate support rod pulling-out equipment, for the steaming frame and steaming bottom plate after completing steaming, the support rod on it is pulled out, realize the disassembly work to the steaming frame and steaming bottom plate stacked together, specific structure and technical effect are described in detail as follows.

[0044] As Figure 1 The support rod pulling-out equipment includes ground beam 1, horizontally moving mechanism 2 is movably installed on ground beam 1, lifting device 3 is provided on horizontally moving mechanism 2, and pull rod device 4 is provided on lifting device 3.

[0045] In the embodiment, horizontal sliding rails are formed on the upper surface of ground beam 1 along the length direction thereof, the lower end of horizontally moving mechanism 2 is provided with a sliding block, the sliding block is matched and installed in the horizontal sliding rails, and power driving mechanism is connected to horizontally moving mechanism 2 to drive horizontally moving mechanism 2 to move along the horizontal sliding rails.

[0046] Lifting device 3 adopts a screw rod lifting mechanism, the screw rod is driven to rotate by a motor, the support frame 5 of pull rod device 4 is fixedly connected to a screw rod nut, and the lifting of pull rod device 4 is realized by cooperating with a guide mechanism. The guide mechanism structure of the embodiment is as follows: a support is mounted on horizontally moving mechanism 2, the support is provided with a vertical sliding rail extending in the height direction, and the support frame 5 of pull rod device 4 is provided with a sliding block matched and installed in the vertical sliding rail.

[0047] As Figure 2 And Figure 3 Pull rod device 4 includes support frame 5, linear module 6, convolution driving mechanism and clamping jaw assembly 12.

[0048] The straight line module 6 is installed on the support frame 5. The rotary driving mechanism comprises a cylinder seat 7, a rotary cylinder 8, a shaft coupling 9, a rotary shaft 10 and a rotary shaft mounting seat 11. The cylinder seat 7 is installed on the straight line module 6, and the rotary cylinder 8 and the rotary shaft mounting seat 11 are installed on both sides of the cylinder seat 7 respectively. The rotary shaft mounting seat 11 is a hollow structure, both ends of which are provided with two bearings, and the rotary shaft 10 is inserted into the hole of the rotary shaft mounting seat 11 and connected with the two bearings. One end of the rotary shaft 10 is connected with the rotary cylinder 8 through the shaft coupling 9, and the other end is fixedly connected with a jaw fixing seat 14 of a jaw assembly 12, so that the jaw assembly 12 can be driven to rotate through the rotation of the rotary cylinder 8.

[0049] As shown in Figure 4 and Figure 5 , the jaw assembly 12 comprises the jaw fixing seat 14, a clamping mechanism, an upper insertion plate 21 and a lower insertion plate 22. The upper insertion plate 21 and the lower insertion plate 22 are installed on both end faces of the jaw fixing seat 14 respectively, and a long groove with a diameter matched with the shape of the support rod is formed on the upper insertion plate 21, the diameter of which is greater than that of the support rod 13 and smaller than that of the boss, and a recess with a diameter matched with the shape of the support rod is also formed on the lower insertion plate 22. Meanwhile, the end of the long groove of the upper insertion plate 21 is provided with a spring piece 23.

[0050] The clamping mechanism comprises a left clamping plate 15, a right clamping plate 16, a guide rod 17, a guide sleeve 18, a left cylinder 19 and a right cylinder 20. The guide rod 17 is fixedly installed on the jaw fixing seat 14 and perpendicular to the length direction of the long groove, and two guide sleeves 18 are sleeved on each guide rod 17, and the left clamping plate 15 and the right clamping plate 16 are fixedly connected with one guide sleeve 18 respectively. The left cylinder 19 and the right cylinder 20 are fixedly installed on the jaw fixing seat 14 and control the left clamping plate 15 and the right clamping plate 16 to move along the guide rod 17 respectively, so as to realize the clamping and opening of the two clamping plates. In this embodiment, in order to facilitate the clamping of the left clamping plate 15 and the right clamping plate 16 on the support rod 13, an arc-shaped groove with a diameter matched with the shape of the support rod 13 is formed on the inner side of the left clamping plate 15 and the right clamping plate 16.

[0051] As shown in Figure 7The working process of the support rod pulling-out device is shown as follows: when the rod pulling-out operation is needed, the rod pulling-out device 4 is brought to the required position by the horizontal moving mechanism 2 and the lifting device 3, and then the linear module 6 moves forward to drive the jaw assembly to move forward, so that the long slot and the groove on the upper and lower insertion plates 21 and 22 of the jaw assembly are clamped into the support rod 13. Next, the lifting device 3 is lifted upward to push the convex table of the support rod 13 from the lower surface of the upper insertion plate 21, so as to pull out the support rod 13 from the hole of the steaming frame and the steaming bottom plate. Since the support rod 13 has a certain space for movement at this time, the central axis of the support rod 13 can be aligned with the central axis of the inserted through hole when the support rod 13 is pulled out, so as to ensure that the support rod 13 is smoothly pulled out, and the support rod 13 is clamped by the clamping mechanism after being pulled out to prevent the support rod from falling off.

[0052] Next, the linear module 6 retreats to reset the jaw assembly 12 to move backward, and then the rotary cylinder 8 rotates by 90 degrees to drive the jaw assembly 12 to rotate, and finally drives the support rod 13 to rotate by 90 degrees, so that the support rod 13 is rotated from the original vertical state to the horizontal state. Then the lifting device 3 is lifted to the appropriate height to place the support rod 13 on the hooks arranged horizontally on the outer surface of the steaming bottom plate or the steaming frame, so as to facilitate the reuse of the support rod 13.

[0053] It is worth mentioning that in the traditional clamping mechanism, two same type cylinders are symmetrically arranged to control one clamping plate respectively. However, in the actual operation process, it is difficult to ensure that the strokes of the two cylinders can be accurately synchronized, which leads to the fact that when the clamping plates controlled by the two cylinders clamp the support rod 13, the position of the support rod 13 often deviates from the center position between the two cylinders and cannot be guaranteed to be at the same position every time. If the limit stroke of the two cylinders is fixed at a certain position to avoid this problem, it will also lead to the decrease of the clamping force of the clamping plate on the support rod 13. Moreover, since the movement of the support rod 13 and the operation of placing the support rod 13 into the hooks arranged horizontally on the outer surface of the steaming bottom plate or the steaming frame are controlled by the center position of the support rod 13 between the two cylinders, it is difficult to accurately place the support rod 13 into the specified position every time in the subsequent operation of the device, thereby affecting the normal operation of the entire production work.

[0054] In view of the above problems, the left cylinder 19 and the right cylinder 20 are improved in the embodiment, and the corresponding control method is matched. Specifically, the left cylinder 19 and the right cylinder 20 are arranged as cylinders with a certain difference in thrust, and during operation, the cylinder with larger thrust is first controlled to move to a specified position, and then the cylinder with smaller thrust works to tightly press the support rod 13 against the clamping plate connected with the cylinder with larger thrust. Since the cylinder moved later has smaller thrust, it can be ensured that the cylinder with larger thrust does not change the stroke on the basis of tightly pressing the support rod 13 to achieve the purpose of clamping the support rod 13, so that the support rod 13 is kept at the center position between the two cylinders.

[0055] In summary, the support rod pulling-out device for the steam curing frame and the steam curing bottom plate in the embodiment ingeniously utilizes the boss structure arranged on the support rod 13 for supporting the steam curing bottom plate or the steam curing frame, and adaptively improves the structure of the clamping device, so that the problem of difficult pulling-out of the support rod is effectively solved.

[0056] The examples described in the present application are only used to describe the preferred embodiments of the present application, and do not limit the concept and scope of the present application. Without departing from the design idea of the present application, various modifications and improvements of the technical solutions of the present application made by the engineers and technicians in the field shall fall within the protection scope of the present application.
