Description

Technical Field

[0001] This utility model relates to the field of gate rod pin insertion and retraction in hydropower stations, and in particular to a shaft shifting mechanism and pin insertion and retraction device. Background Technology

[0002] Most double-curvature arch dam hydropower stations have flood discharge deep-hole emergency gate slots designed as inclined gate slots. In order to meet the requirements for lowering the gate, the gantry crane will be connected to the gate through tie rods for operation. Multiple tie rods are required to complete the lowering operation when the gate is lowered. The tie rods are connected together by pins.

[0003] The dam top gantry crane comes with a set of tie rod shifting device when it leaves the factory. However, during use, it is necessary to adjust the pin position multiple times to align the holes. In addition, the pin bearing load position cannot be moved and the pin insertion and removal mechanism cannot be moved, which makes the pin insertion and removal work inefficient. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is: how to quickly align the pins and improve the efficiency of pin insertion and retraction.

[0005] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a shifting axis mechanism, including a vertical alignment component, the vertical alignment component including a base frame, a lifting frame provided on the upper part of the base frame, and a platform provided on the upper part of the lifting frame; and a horizontal alignment component, the horizontal alignment component including a bearing frame slidably disposed on the platform, the bearing frame having at least two bearing positions arranged side by side, the sliding direction of the bearing frame being consistent with the arrangement direction of the bearing positions.

[0006] In a preferred embodiment of the shifting mechanism of this utility model: the lifting frame includes a scissor frame disposed on the base frame, a first driving member is hinged to the scissor frame, the end of the first driving member away from the scissor frame is hinged to the base frame, and the upper end of the scissor frame is connected to the platform.

[0007] In a preferred embodiment of the axis shifting mechanism of this utility model: the lateral alignment component further includes a first sliding frame fixedly disposed on the platform, the bearing frame includes a first support frame slidably disposed on the first sliding frame, a bearing plate is fixedly disposed on the first support frame, and the bearing station is an arc-shaped groove disposed on the bearing plate.

[0008] In a preferred embodiment of the axis shifting mechanism of this utility model: the lateral alignment component further includes a second driving member, one end of which is mounted on the first support frame and the other end of which is mounted on the platform.

[0009] In a preferred embodiment of the shifting axis mechanism of this utility model: a pad is provided on the inner wall of the bearing station, and the pad is an arc-shaped plate adapted to the shape of the bearing station.

[0010] In a preferred embodiment of the axis shifting mechanism of this utility model: the pad is installed in the bearing station by means of bolt detachment.

[0011] In a preferred embodiment of the shifting mechanism of this utility model, it further includes a hydraulic pump station mounted on the base frame, wherein the first driving member and the second driving member are both oil cylinders connected to the hydraulic pump station.

[0012] In a preferred embodiment of the axis-shifting mechanism of this utility model, the vertical alignment component further includes a moving wheel disposed at the lower part of the base frame.

[0013] The beneficial effects of this utility model are as follows: By adjusting the height of the platform and the lateral position of the support frame, the pin hole and the support station are aligned, making the alignment operation simpler and more efficient, thereby improving the efficiency of pin insertion and removal; at the same time, the support frame has at least two support stations. After one pin is inserted and removed, the support frame is moved laterally so that the next support station and the pin hole of the tie rod are aligned, and the pin insertion and removal of the next tie rod section can be carried out, further improving the pin insertion and removal efficiency.

[0014] To address the problem of low alignment efficiency caused by the inability of the pin insertion / retraction mechanism to move in existing technologies, this application proposes a pin insertion / retraction device, including the aforementioned pin shifting mechanism, and further including a push-pull assembly. The push-pull assembly includes a second sliding frame fixedly mounted on a platform, a second support frame slidably mounted on the second sliding frame, an electro-hydraulic push rod mounted on the second support frame, a connector mounted on the electro-hydraulic push rod, and a third driving component mounted on the second support frame. The end of the third driving component away from the second support frame is mounted on the platform, and the third driving component is a hydraulic cylinder.

[0015] In a preferred embodiment of the pin insertion and withdrawal device of this utility model, a connecting component is further included, the connecting component including a connecting plate disposed on the base frame, and a positioning pin is inserted through the connecting plate.

[0016] The beneficial effects of this utility model are as follows: since the push-pull assembly is movably set on the platform, the position of the push-pull assembly can be easily adjusted, thereby improving the hole alignment efficiency between the push-pull assembly and the pull rod pin hole, and improving the pin insertion and retraction efficiency.

[0026] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0027] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0028] Example 1, referring to Figure 1-2 This embodiment provides a tilting mechanism, including:

[0029] The vertical alignment component 1 includes a base frame 11, a lifting frame 12 is provided on the upper part of the base frame 11, and a platform 13 is provided on the upper part of the lifting frame 12.

[0030] The lateral alignment component 2 includes a support frame 21 that is slidably mounted on the platform 13. The support frame 21 is specifically positioned near the edge of the platform 13 so that when the tie rod pin is inserted or retracted, the support station 22 is positioned close to the tie rod. At least two support stations 22 are arranged side by side on the support frame 21, and the sliding direction of the support frame 21 is consistent with the arrangement direction of the support stations 22.

[0031] The shifting mechanism delivers the pin 9 that needs to be inserted into the tie rod 8 to the pin hole of the tie rod 8, or removes the pin 9 that needs to be removed from the tie rod 8. The pin 9 that needs to be inserted into or removed from the tie rod 8 is specifically placed on the bearing station 22. This improves the alignment speed between the bearing station 22 and the pin hole of the tie rod 8, thereby improving the insertion and removal efficiency of the pin 9. In actual use, one end of the bearing station 22 is close to the pin hole of the tie rod 8. The lifting frame 12 adjusts the height position of the platform 13 so that the bearing station 22 is aligned with the tie rod 8 at the same height. The pin holes are aligned by sliding the support frame 21 on the platform 13 to adjust the lateral position of the support station 22, so that the support station 22 is aligned with the pin hole of the tie rod 8 in the horizontal direction, thereby realizing the alignment of the support station 22 and the pin hole of the tie rod 8; at the same time, since the support frame 21 has at least two support stations 22, it can support at least two pins 9 at a time. After one pin 9 is inserted and removed, the support frame 21 is moved laterally so that the next support station 22 is aligned with the pin hole of the tie rod 8, and the pin insertion and removal of the next section of the tie rod 8 can be carried out.

[0032] Because the tie rod 8 is relatively large, it is cumbersome to align the pin hole with the bearing station 22 by adjusting the position of the tie rod 8 in the traditional way, and multiple adjustments of the tie rod 8 are required to align the hole. This application aligns the pin hole with the bearing station 22 by adjusting the height of the platform 13 and the lateral position of the bearing frame 21. The hole alignment operation is simpler and more efficient, thereby improving the efficiency of pin insertion and retraction. At the same time, the bearing frame 21 has at least two bearing stations 22. After one pin 9 is inserted and retracted, the bearing frame 21 is moved laterally to align the next bearing station 22 with the pin hole of the tie rod 8, so that the pin insertion and retraction of the next section of the tie rod 8 can be carried out, further improving the efficiency of pin insertion and retraction.

[0033] Preferred, refer to Figure 1 and Figure 3 The lifting frame 12 includes a scissor frame 121 mounted on the base frame 11. A first driving member 122 is hinged to the scissor frame 121. The end of the first driving member 122 away from the scissor frame 121 is hinged to the base frame 11. The upper end of the scissor frame 121 is connected to the platform 13.

[0034] The first driving component 122 drives the scissor frame 121 to rise and fall, thereby driving the platform 13 to rise and fall. The scissor frame 121 is specifically installed as follows: the lower end of the scissor frame 121 is hinged to the base frame 11 on one side, and the other side is slidably mounted on the base frame 11; similarly, the upper end of the scissor frame 121 is hinged to the bottom of the platform 13 on one side, and the other side is slidably mounted on the bottom of the platform 13.

[0035] Example 2, refer to Figure 2 and Figure 4 The lateral alignment component 2 also includes a first sliding frame 23 fixedly mounted on the platform 13. The support frame 21 includes a first support frame 211 slidably mounted on the first sliding frame 23. A support plate 212 is fixedly mounted on the first support frame 211. The support station 22 is an arc-shaped groove mounted on the support plate 212.

[0036] Because the pin 9 of the tie rod 8 is large in size and weight, in actual design, the first sliding frame 23 is designed as two, and the two sides of the bearing frame 21 are slidably connected to the two first sliding frames 23 respectively, so as to provide good support for the bearing frame 21 and the bearing plate 212.

[0037] When the pin 9 of the tie rod 8 is inserted or retracted, one side of the platform 13 is close to the tie rod 8, and the bearing plate 212 is set on the side of the platform 13 close to the tie rod 8. In order to make the bearing plate 212 close to the tie rod 8 when the pin 9 is inserted or retracted, the outer end of the bearing plate 212 is flush with the edge of the platform 13 or the outer end of the bearing plate 212 extends out of the platform 13.

[0038] Preferred, refer to Figure 2 The lateral alignment component 2 also includes a second drive member 24, one end of which is mounted on the first support frame 211 and the other end of which is mounted on the platform 13.

[0039] Since the pin 9 of the tie rod 8 is large in size and weight, in order to ensure sufficient driving force, two second driving components 24 are also set, and the two second driving components 24 are symmetrically arranged on both sides of the support frame 21.

[0040] Preferred, refer to Figure 2 and Figure 4 The inner wall of the bearing station 22 is provided with a pad 213, which is an arc-shaped plate adapted to the shape of the bearing station 22; the pad 213 is installed in the bearing station 22 by bolt detachment.

[0041] Because the pin of the tie rod 8 is large in size and weight, the inner wall of the bearing station 22 is easily damaged. By setting a pad 213, the inner wall of the bearing station 22 is protected and the damage is reduced. The pad 213 is installed by bolt removal, which makes it easy to replace when damaged.

[0042] Preferred, refer to Figure 1 The shifting mechanism also includes a hydraulic pump station 3 mounted on the base frame 11, and the first drive component 122 and the second drive component 24 are both oil cylinders connected to the hydraulic pump station 3.

[0043] Because the overall structure of the equipment is large and requires a large driving force, both the first driving component 122 and the second driving component 24 are hydraulic cylinders.

[0044] Preferred, refer to Figure 1 The vertical alignment component 1 also includes a movable wheel 14 disposed at the lower part of the base frame 11.

[0045] The lower part of the base frame 11 is equipped with casters 14 to facilitate the overall movement of the equipment.

[0046] Example 3, referring to Figure 5-8 A pin insertion and withdrawal device includes an upper shaft shifting mechanism, and further includes,

[0047] The push-pull assembly 4 includes a second sliding frame 41 fixedly mounted on the platform 13, a second support frame 42 slidably mounted on the second sliding frame 41, an electro-hydraulic push rod 43 mounted on the second support frame 42, a connector 44 mounted on the electro-hydraulic push rod 43, and a third driving component 45 mounted on the second support frame 42. The end of the third driving component 45 away from the second support frame 42 is mounted on the platform 13, and the third driving component 45 is a hydraulic cylinder.

[0048] After the bearing station 22 and the pin hole of the pull rod 8 are aligned, the push-pull assembly 4 is used to connect the pin 9 of the pull rod 8. The pin 9 is pushed into the pin hole of the pull rod 8 or pulled out of the pull rod 8 to realize the insertion and retraction of the pull rod pin. Specifically, the position of the bearing station 22 is adjusted so that it is aligned with the pin hole of the pull rod 8. When the pin 9 is inserted, the electro-hydraulic actuator 43 starts to extend, driving the connector 44 to move closer to the pin 9 on the bearing station 22, and finally causing the connector 44 to extend into the center hole at the end of the pin 9. The electro-hydraulic actuator 43 continues to extend, pushing the pin 9 into the pin hole of the pull rod 8; when the pin 9 retracts, the electro-hydraulic actuator 43 starts to extend, driving the connector 44 to move closer to the pin 9 on the pull rod 8, and finally causing the connector 44 to extend into the center hole at the end of the pin 9. Then the electro-hydraulic actuator 43 retracts, pulling the pin 9 out of the pull rod 8 to the bearing station 22; wherein, the connector 44 and the electro-hydraulic actuator 43 are detachably connected, and the connector 44 is specifically connected to the center hole at the end of the pin 9 by a threaded connection.

[0049] Specifically, the height difference between the centerline of the connector 44 and the arc bottom of the bearing station 22 is the same as the radius of the pin 9, so that when the bearing station 22 and the pin hole of the pull rod 8 are aligned in the height direction, the connector 44 is also aligned with the pin hole of the pull rod 8 in the height direction. The lateral position of the second support frame 42 is adjusted by the third drive component 45, thereby adjusting the lateral position of the electro-hydraulic push rod 43 and the connector 44, so that the connector 44 is aligned with the pin hole of the pull rod 8 in the horizontal direction, thereby realizing the alignment of the connector 44 and the pin hole of the pull rod 8. Since the push-pull assembly 4 is movably set on the platform 13, the position of the push-pull assembly 4 can be easily adjusted, thereby improving the alignment efficiency of the push-pull assembly 4 and the pin hole of the pull rod 8, and improving the pin insertion and retraction efficiency.

[0050] In actual use, vision cameras are installed on both the base frame 11 and the second support frame 42, which are used in conjunction with hydraulic drive for automatic positioning.

[0051] Preferred, refer to Figure 5 and Figure 7 The pin insertion and withdrawal device also includes a connecting component 5, which includes a connecting plate 51 disposed on the base frame 11, and a positioning pin 52 is disposed on the connecting plate 51.

[0052] When the pin is inserted or removed from the tie rod 8, the tie rod is usually fixed by the locking beam 7. The connecting plate 51 is used to connect the entire device to the locking beam 7 during the pin insertion or removal operation to ensure the device is fixed in position and to ensure the stability of the operation. The connecting plate 51 is specifically connected to the locking beam 7 by the positioning pin 52. Of course, both the connecting plate 51 and the locking beam 7 have corresponding pin holes.

[0053] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
