Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic hoist auxiliary devices, and more specifically to an installation auxiliary device for a hydraulic hoist. Background Art

[0002] For a long time, radial gates have been widely used in water conservancy and hydropower projects. With the development and progress of the economy, the construction of reservoirs and power stations, radial gates have been more widely used due to their good force-bearing performance and working characteristics that are not restricted by water flow conditions. The driving force of radial gates is generally provided by the matching hydraulic hoist.

[0003] The existing hydraulic gate hoist is used in conjunction with a sluice gate, so the overall weight of the hydraulic gate hoist is relatively large. During installation, a pin rod is required to connect the piston rod of the hydraulic gate hoist with the transmission structure of the gate. However, the hydraulic gate hoist is heavy and inconvenient to lift, which makes the pin rod difficult to install. In view of this, we propose an installation auxiliary device for the hydraulic gate hoist. Utility Model Content

[0020] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] This embodiment provides an auxiliary installation device for a hydraulic hoist. Figure 1, including a central axis 1, a swing arm 1 2 and a swing arm 2 3. The central axis 1 can be connected to a handle for rotational drive, wherein the swing arm 1 2 is fixedly connected to the middle part of the central axis 1 perpendicular to the axis of the central axis 1. When the central axis 1 rotates, the swing arm 1 2 will rotate synchronously with the central axis 1, and the end of the swing arm 2 3 is sleeved and rotatably installed on the outside of the central axis 1. When the central axis 1 rotates, the swing arm 2 3 remains stationary relative to the central axis 1 and will not rotate with the central axis 1. Moreover, the swing arm 2 3 is arranged parallel to the swing arm 1 2, and the rotation of the swing arm 1 2 is relative to the swing arm 2 3. The rotation of the swing arm 1 2 and the swing arm 2 3 makes the end away from the central axis 1 approach or move away from each other. When in use, the end of the rocker arm 2 3 away from the central axis 1 is slidably installed with a positioning rod 4, and the positioning rod 4 can be reversely inserted into the hole of the mounting pin 7 of the sluice transmission member 8. At this time, the end of the swing arm 2 away from the central axis 1 is installed with a mounting seat 5 for connecting the hydraulic cylinder 6. When the swing arm 1 2 rotates, the hydraulic cylinder 6 can be driven to approach the sluice transmission member 8 until the holes of the mounting pin 7 of the sluice transmission member 8 and the hydraulic cylinder 6 are aligned, which is convenient for installing the pin 7.

[0022] Furthermore, a motor can be installed at the end of the middle axis 1, and the motor frame of the motor is installed on the vertical side wall of the rocker arm 2 3 close to the middle axis 1. When the motor is working, it can drive the rocker arm 1 2 to rotate automatically, and a motor with a shaft lock can be used to position it when it rotates into place, ensuring that the positions of the rocker arm 1 2 and the rocker arm 2 3 remain unchanged during the installation of the pin rod 7, making it more convenient to install the pin rod 7 smoothly.

[0023] Reference Figure 2 A side frame is fixedly arranged parallel to the side wall of the rocker arm 2 3, and a Y-shaped design is adopted between the rocker arm 2 3 and the side frame, so that an installation gap can be formed near one end of the middle axis 1. At this time, the swing arm 1 2 is installed between the rocker arm 2 3 and the side frame, and the side frame is rotatably connected to the middle axis 1. When the middle axis 1 rotates, the middle axis 1 can be stably supported to ensure that the rotation of the swing arm 1 2 relative to the rocker arm 2 3 is more stable. Bearings are respectively installed at the connecting positions of the rocker arm 2 3, the side frame and the middle axis 1, so as to improve the rotation stability during long-term use.

[0024] Reference Figure 3 The rocker arm 2 3 includes a main body 31. The main body 31 adopts a plate-like structure and is provided with a through hole at one end away from the central axis 1. A sliding sleeve 32 is fixedly installed at the end of the main body 31 away from the central axis 1. The sliding sleeve 32 is installed through the through hole and fixed, and an installation space can be formed at the lower end of the main body 31. When in use, a positioning rod 4 is slidably installed in the sliding sleeve 32. The positioning rod 4 is first reversely inserted into the hole for installing the pin rod 7 of the sluice transmission member 8. When the pin rod 7 is positively installed in the pin rod 7 installation hole of the sluice transmission member 8, the pin rod 7 can push out the positioning rod 4, and no subsequent disassembly is required. The position of the positioning rod 4 can also be used to intuitively judge whether the pin rod 7 is installed in place between the sluice transmission member 8, and the installation operation is more convenient.

[0025] Reference Figure 4 A sliding cavity 33 is provided on the inner side of the sliding sleeve 32, and a limiting ring 9 is installed in the middle of the positioning rod 4. The positioning rod 4 slides freely through the sliding sleeve 32, and the limiting ring 9 is slidably set in the sliding cavity 33 and cannot be detached. At this time, during use, the positioning rod 4 will be limited in the sliding sleeve 32 and will not be completely detached, thereby preventing the pin rod 7 from pushing the positioning rod 4 out of the mounting hole of the sluice transmission member 8 and causing it to fall and be lost.

[0026] Reference Figure 4 A through hole is opened in the middle of the sliding sleeve 32, and the sliding cavity 33 is arranged in the middle of the through hole, wherein the inner diameter of the through hole is equal to the outer diameter of the positioning rod 4. At the same time, the inner diameter of the sliding cavity 33 is larger than the outer diameter of the positioning rod 4, which can ensure that the positioning rod 4 can slide smoothly in the sliding sleeve 32, and the limiting ring 9 is protruding from the circumferential side wall of the positioning rod 4, and the limiting ring 9 is in sliding contact with the inner wall of the sliding cavity 33, which can ensure that the contact area between the positioning rod 4 and the sliding sleeve 32 is large, and when the sliding and insertion of the sluice transmission member 8 is subjected to extrusion force, the horizontal stability of the positioning rod 4 can be ensured.

[0027] Reference Figure 3 The mounting base 5 includes a connecting frame 51, and the connecting frame 51 is connected to the swing arm 2 at one end thereof. When the hydraulic cylinder 6 is connected, a strap 52 is installed on the side wall of the connecting frame 51, and only one end of the strap 52 is fixedly installed on the connecting frame 51. The strap 52 can be passed around the hydraulic cylinder 6 and tightened. When the swing arm 2 rotates, the rocker arm 2 3 is installed at the position of the water gate transmission member 8 through the positioning rod 4. When the swing arm 2 is close to the rocker arm 2 3, the hydraulic cylinder 6 can be close to the water gate transmission member 8. The mounting hole of the water gate transmission member 8 can be aligned with the mounting hole on the piston rod of the hydraulic cylinder 6 by rotating the swing arm 2 and the rocker arm 2 3 as a whole, so that the connection is convenient to use.

[0028] Reference Figure 3 The connecting frame 51 is rotatably connected to the end of the swing arm 2. A round hole is opened at the end of the swing arm 2 and the connecting rod 51 is rotatably inserted into the round hole, so that the connecting rod 51 can rotate relative to the swing arm 2, thereby preventing the strap 52 from being twisted and loosened or broken when the swing arm 2 and the rocker arm 2 3 are rotated as a whole. In addition, a socket with a middle hole is installed at the end of the connecting frame 51. When the strap 52 is installed, the end of the strap 52 can be inserted into the middle hole of the socket. At the same time, a clamping piece is installed at the position of the socket at the middle hole. The clamping piece adopts a bolt, which can be tightened to press the strap 52. Similarly, the clamping piece can also adopt other components or structures that can fix the strap 52 and the socket, such as a triangular wedge block. As long as the effect of detachably fixing the strap 52 can be achieved, other replacement structures can also be used, which will not be repeated here.
