Description

Technical Field

[0001] The utility model belongs to the technical field of hoists and relates to a mounting frame for a small hoist. Background Technique

[0002] The sluice hoist is used in various water supply and drainage, water conservancy and hydropower projects to control the lifting of various cast iron gates and steel gates to achieve opening and closing. It includes a screw hoist, which has a very simple structure and is relatively easy to install. It is widely used in the sluices of channels and the gate opening and closing of diversion hubs.

[0003] A small hoist is generally used to drive a small gate to lift. When installing a screw hoist, it needs to be fixed to the mounting plate embedded in the cement through bolts. After the hoist is installed, it cannot swing or move. The position of the hoist must be installed directly above the connection part of the gate to connect the bottom of the screw to the gate, which requires high installation accuracy and great installation difficulty.

[0004] Based on this, we designed a mounting frame for a small hoist. Summary of the Utility Model

[0005] The purpose of the utility model is to address the above problems in the existing technology and propose a mounting frame for a small hoist. The technical problem to be solved by this device is: how to reduce the installation difficulty of the hoist and facilitate the installation for the operator.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A mounting frame for a small hoist includes a buried plate. A round hole is provided in the middle of the buried plate, and a ring is fixed above the round hole. Two symmetrically distributed first fixed shafts are fixed on the outer side of the ring. A first swing frame is arranged on the outer side of the ring, and two symmetrically distributed first rotation holes are provided on both sides of the first swing frame. The first swing frame is rotationally connected to the first fixed shaft through the first rotation holes. Two symmetrically distributed columns are fixed on the first swing frame, and the columns are distributed at intervals from the first rotation holes. A second fixed shaft is fixed on the columns. A second swing frame is arranged above the first swing frame, and two symmetrically distributed second rotation holes are provided on both sides of the second swing frame. The second swing frame is rotationally connected to the second fixed shaft through the second rotation holes. A plurality of connecting pieces for connecting the base of the hoist are arranged above the second swing frame.

[0008] A flange is provided at the edge of the buried plate, and a plurality of stabilizing rods are provided at the bottom of the buried plate.

[0009] With the above structure, when the buried plate is buried in the cement, the flange and the stabilizing rods can improve the connection stability between the buried plate and the cement, so that the hoist remains stable during long-term use.

[0010] Two symmetrically distributed support blocks are fixed on the embedded plate, and two first gaskets are fixed at the upper ends of the support blocks. The first gaskets are located below the column. A number of second gaskets are fixed on the first swing frame, and the second gaskets are located below the second swing frame.

[0011] With the above structure, during use, the first gasket can limit the tilting angle of the first swing frame, and the second gasket can limit the tilting angle of the second swing frame, preventing the tilting angle of the second swing frame from being too large, which may cause the hoist to jam during use.

[0012] A number of circumferentially evenly distributed fixing columns are fixed on the second swing frame. One end of the connecting piece is rotatably connected to the fixing column, and the other end of the connecting piece is provided with a mounting hole.

[0013] With the above structure, when installing the hoist, the base of the hoist can be connected to the mounting holes at the corresponding positions by bolts, and the connecting piece can rotate freely, so that the distance between the mounting holes can be adjusted. Therefore, hoists of different sizes can be installed, expanding the applicable range of the mounting frame.

[0014] A number of circumferentially evenly distributed support members are fixed on the second swing frame. The upper surface of the support member is flush with the upper surface of the connecting piece, and the support member and the connecting piece are distributed alternately.

[0015] With the above structure, after installing the hoist, the support member and the connecting piece can jointly provide support force for the hoist, improving the stability of the hoist and preventing the connecting piece from being damaged.

[0016] Compared with the prior art, the mounting frame of this small hoist has the following advantages:

[0017] 1. Through the embedded plate, the first swing frame, the second swing frame and the connecting piece, the hoist can still swing slightly after installation. When there is a small offset between the hoist and the gate position, the hoist can still be installed and used, reducing the installation accuracy requirements between the hoist and the gate, reducing the installation difficulty, and facilitating the operator to install.

[0018] 2. Through the connecting piece and the fixing column, the connecting piece can rotate along the fixing column, thereby adjusting the distance between each mounting hole, and hoists of different sizes can be installed, expanding the applicable range of the mounting frame.

[0019] 3. Through the first gasket and the second gasket, the tilting angles of the second swing frame and the first swing frame are limited, preventing the tilting angle of the hoist from being too large during installation, which may cause the tilting angle between the screw rod and the gate to be too large during use and cause the device to jam.

[0029] Please refer to Figures 1-4, this embodiment provides a mounting frame for a small hoist, including a buried plate 1. A circular hole 2 is opened at the middle position of the buried plate 1, and a circular ring 3 is fixed above the circular hole 2. Two symmetrically distributed first fixed shafts 4 are fixed on the outer side of the circular ring 3. A first swing frame 5 is arranged on the outer side of the circular ring 3, and two symmetrically distributed first rotation holes 6 are opened on both sides of the first swing frame 5. The first swing frame 5 is rotationally connected to the first fixed shaft 4 through the first rotation holes 6. Two symmetrically distributed columns 7 are fixed on the first swing frame 5, and the columns 7 are distributed at intervals from the first rotation holes 6. A second fixed shaft 8 is fixed on the columns 7. A second swing frame 9 is arranged above the first swing frame 5, and two symmetrically distributed second rotation holes 10 are opened on both sides of the second swing frame 9. The second swing frame 9 is rotationally connected to the second fixed shaft 8 through the second rotation holes 10. A plurality of connecting pieces 11 for connecting the base of the hoist are arranged above the second swing frame 9.

[0030] A flange 12 is arranged at the edge of the buried plate 1, and a plurality of stabilizing rods 13 are arranged at the bottom of the buried plate 1; when the buried plate 1 is buried in the cement, the flange 12 and the stabilizing rods 13 can improve the connection stability between the buried plate 1 and the cement, so that the hoist remains stable during long-term use.

[0031] Two symmetrically distributed support blocks 14 are fixed on the buried plate 1, and two first gaskets 15 are fixed at the upper ends of the support blocks 14, and the first gaskets 15 are located below the columns 7. A plurality of second gaskets 16 are fixed on the first swing frame 5, and the second gaskets 16 are located below the second swing frame 9; during use, the first gaskets 15 can limit the tilting angle of the first swing frame 5, and the second gaskets 16 can limit the tilting angle of the second swing frame 9, preventing the tilting angle of the second swing frame 9 from being too large and causing the hoist to jam during use.

[0032] A plurality of circumferentially evenly distributed fixing columns 17 are fixed on the second swing frame 9. One end of the connecting piece 11 is rotationally connected to the fixing column 17, and an installation hole 18 is opened at the other end of the connecting piece 11; when installing the hoist, the base of the hoist can be bolted to the installation hole 18 at the corresponding position, and the connecting piece 11 can rotate freely, so that the distance between the installation holes 18 can be adjusted. Therefore, hoists of different sizes can be installed, expanding the applicable range of the mounting frame.

[0033] A plurality of circumferentially evenly distributed support members 19 are fixed on the second swing frame 9. The upper surface of the support member 19 is flush with the upper surface of the connecting piece 11, and the support member 19 and the connecting piece 11 are distributed at intervals; after installing the hoist, the support member 19 and the connecting piece 11 can jointly provide a supporting force for the hoist, improving the stability of the hoist and preventing the connecting piece 11 from being damaged.

[0034] In this embodiment, the above fixing methods are all the most commonly used fixed connection methods in the art, such as welding, bolt connection, etc.

[0035] Working principle of the utility model:

[0036] Before use, embed the embedded plate 1 in the cement base. The stabilizing rod 13 and the flange 12 will improve the stability of the embedded plate 1. When installing the hoist, fix the bottom of the hoist to the corresponding mounting holes 18 with bolts, and keep each connecting piece 11 symmetrically distributed around the center to prevent the hoist from shaking. At this time, the connecting piece 11 and the support piece 19 jointly provide the supporting force, and at this time, the hoist is relatively fixed to the second swing frame 9. The second swing frame 9 can swing along the axis of the second fixed shaft 8. At the same time, the second swing frame 9 can also swing along the first fixed shaft 4 together with the first swing frame 5, so that the hoist can swing in any direction. The first gasket 15 and the second gasket 16 can limit the swing amplitude of the second swing frame 9 to prevent the hoist from being installed too obliquely, resulting in too large an offset angle between the screw rod and the gate and jamming during use. Under this condition, when there is a small offset between the position of the hoist and the gate, it can still be installed and used, reducing the installation accuracy requirements between the hoist and the gate, reducing the installation difficulty, and facilitating the operator to install. In addition, the connecting piece 11 can rotate freely, so that the distance between the mounting holes 18 can be adjusted, so different sizes of hoists can be installed, expanding the applicable range of the mounting frame.

[0037] The above describes the preferred embodiments of the patent in detail, but the patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the patent.
