Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, in particular to a valve seat hopper fixing frame for cranes. Background Art

[0002] Cranes are lifting equipment used in many aspects such as modern building construction. There are many types of cranes. According to the lifting properties, they can be divided into mobile cranes, tower cranes, and mast cranes. Among them, the more convenient to use are vehicle-mounted cranes. When the crane is hoisting and transporting the bucket, in order to prevent the bucket with the valve seat from shaking, the bucket is limited by installing a fixed frame to ensure the stability of the bucket during the hoisting process. Although the stability of the bucket hoisting process can be ensured, the fixed frame is installed in a fixed manner, which makes it inconvenient to adjust the fixed frame, resulting in a smaller scope of application of the device.

[0003] After searching, the Chinese patent document (authorization announcement number CN216190472U) shows that this utility model relates to the technical field of crane auxiliary equipment and discloses a fixed frame for cranes, including a base and a body, the body is fixedly arranged on the upper surface of the base, the outer wall of the base is provided with a first annular plate rotatably arranged through a bearing, a second annular plate fixedly sleeved with the base is arranged below the first annular plate, a supporting mechanism is fixedly arranged on the right side of the lower surface of the first annular plate, a limiting mechanism is fixedly arranged on the left side of the upper surface of the first annular plate, and a plurality of slots are opened around the upper surface of the second annular plate. Although this patent can ensure the stability of the hopper hoisting process, the fixed frame adopts a fixed installation method and can also be on the side of the crane, which is not convenient for adjustment, resulting in a small scope of application of the device.

The technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail. However, where appropriate, the technologies, methods and equipment should be regarded as part of the specification, and the proportions of the devices in the drawings are for reference only and may be adjusted to a certain extent according to actual usage.

[0026] Examples, such as Figures 1 to 4 As shown, two symmetrical installation boxes 9 are installed on the side of the gantry 2, and the inner side of the installation box 9 is fixedly connected with a guide rod 15. The gantry 2 can be used with the winch 33 to form a crane. The design of the guide rod 15 can ensure the directional movement of the installation frame 10, and the outer periphery of the guide rod 15 is slidably connected with the installation frame 10 that is connected to the installation box 9, and a reset spring 17 is installed between the side of the installation frame 10 and the inner bottom wall of the installation box 9. The reset spring 17 can drive the installation frame 10 to reset and make the installation frame 10 have a certain adjustment ability. The vertical inner side of the installation frame 10 is rotatably connected with a screw rod 13 for auxiliary adjustment, and the side of the installation frame 10 is installed with a screw rod 13 that provides adjustment power for the screw rod 13. The stepper motor 11 and the screw rod 13 are of two-stage design, which can drive the two adjusting rods 18 to move toward each other, and the outer periphery of the screw rod 13 is threadedly connected to two adjusting rods 18 that are slidably connected to the inner wall of the mounting frame 10, and a rectangular movable plate 12 is welded at one end of the adjusting rod 18, and a plurality of positioning rods 14 are welded on the opposite sides of the two movable plates 12. A hopper body 7 with a valve seat is hoisted at the bottom end of the adjusting component 3. The hopper body 7 has an existing device valve seat, which can facilitate the unloading operation, and the outer periphery of the hopper body 7 is welded with a limit plate 8 with a positioning hole, and the design of the positioning hole is compatible with the positioning rod 14. The hopper body 7 may shake during the adjustment conversion, but it does not affect the normal use of the device.

[0027] A through-type mounting groove is provided at the bottom end of the base 1, and a plurality of moving wheels 16 for facilitating the movement of the gantry 2 are installed on the inner side of the mounting groove. An auxiliary plate 4 is fixedly connected to the side of the mounting box 9, and a scraper 5 for auxiliary cleaning is installed at the bottom end of the auxiliary plate 4. The design of the scraper 5 and the cleaning brush 6 can clean the moving path of the base 1, effectively preventing the gantry 2 from shaking when moving, and the number of the scraper 5 and the cleaning brush 6 is determined according to actual conditions, and a cleaning brush 6 is installed on the side of the scraper 5.

[0028] The adjustment component 3 includes an adjustment slot provided at the top of the gantry 2, a slide bar 31 installed on the inner side of the adjustment slot, and a slider 32 installed on the outer periphery of the slide bar 31. The top of the slider 32 is fixedly connected with a mounting plate 34, and a winch 33 is installed at the bottom end of the slider 32, and the rope end of the winch 33 is connected to the hopper body 7. The top of the mounting plate 34 is installed with a fixed end of a driving motor 35, and the driving end of the driving motor 35 is connected with a gear 36. By starting the driving motor 35, the gear 36 is driven to rotate, and the rotation of the gear 36 cooperates with the linkage plate 37, so that the slider 32 moves along the extension direction of the slide bar 31, thereby achieving the adjustment effect. The top of the gantry 2 is installed with a linkage plate 37 meshing with the gear 36.

[0029] The winch 33, the drive motor 35 and the stepper motor 11 are all conventional instruments. Their working principles, sizes and models are irrelevant to the functions of the present application, so they will not be described in detail. They are all controlled by a remote control switch. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices. Therefore, the present invention will no longer explain the control method and circuit connection in detail, and the proportions of the drawings are for reference only and can be adjusted to a certain extent according to actual usage.

[0030] How it works

[0031] The valve seat hopper fixing frame for the crane is used. When in use, the driving motor 35 is started according to actual cleaning to drive the gear 36 to rotate. The rotation of the gear 36 drives the slider 32 to adjust along the extension direction of the slide bar 31. The adjustment of the slider 32 drives the winch 33 to adjust. After the adjustment is completed, the winch 33 is started to release the rope to connect with the hopper body 7. After the connection is completed, the winch 33 is started to drive the hopper body 7 to rise to a certain height. The stepping motor 11 is started to drive the screw rod 13 to rotate. The rotation of the screw rod 13 drives the movable plates 12 on the sides of the two adjusting rods 18 to move toward each other, so that the positioning rod 14 can be embedded in the positioning hole on the side of the limit plate 8. After the positioning is completed, the gantry 2 can move.
