Description

Technical Field

[0001] The utility model belongs to the technical field of cast iron pipe production, and mainly relates to a device for automatically packing and putting ductile iron pipes into a health pool. Background Art

[0002] Ductile iron pipe is a pipe made of ductile iron material. Through a specific casting process, the graphite inside the pipe is distributed in a spherical shape. Ductile iron pipe has high strength, good toughness and plasticity, and its comprehensive mechanical properties are close to those of steel. Due to the spherical distribution of graphite inside, ductile iron pipe has good corrosion resistance, smooth pipe wall, low water flow resistance, which is conducive to fluid transportation. It is widely used in water supply, gas and industrial pipeline systems.

[0003] In the production of ductile iron pipes, after the inner walls of small-diameter pipes are coated with cement, they need to be placed in a curing tank for curing to ensure the proper solidification of the cement. This operation is currently performed manually by hanging two steel ropes under the overhead crane hoist at the axial ends of a row of pipes. During the lifting process, pipes can easily fall off, and even fall and injure personnel and equipment. Furthermore, during the lifting process, adjacent pipes can collide with each other due to shaking, causing cement to fall, resulting in low-quality ductile iron pipes. Utility Model Content

The overhead crane pulls up the steel cable, and the fixed seat moves up to pull up the cast iron pipe, and the cast iron pipe is clamped into the corresponding placement groove. The two clamping groove walls clamp the cast iron pipe to prevent the cast iron pipes from colliding with each other during lifting and causing the cement inside the pipe to fall off, so as to solve the problem of low quality of the cast iron pipe due to the falling off of the cement inside the pipe, and save the step of manually hanging the rope, thereby reducing the labor intensity of employees.

[0008] Furthermore, the fixed seat includes a placement seat section, a connecting plate section and a sliding plate section that are connected to each other and distributed from bottom to top. The placement groove is located on the placement seat section, and a limit plate is provided on the outer side of the placement groove relative to the hanging plate to prevent the cast iron pipe from slipping out of the placement groove during lifting.

[0009] Beneficial effect: The limit plate can prevent the cast iron pipe from sliding out of the outer side of the placement groove during lifting, thereby ensuring the stability of the cast iron pipe during lifting and solving the problem of the cast iron pipe falling.

[0010] Furthermore, a sliding cavity extending in the left and right directions is provided in the hanging plate, and a support plate is provided in the middle of the sliding cavity to divide the sliding cavity into two chambers.

[0013] Furthermore, there are four steel cables, and the lengths of the four steel cables are kept consistent at all times. The hanging plate is provided with four hanging holes distributed in a rectangular shape for connecting the steel cables and the hanging plate.

[0014] Beneficial effect: The lengths of the four steel cables are always kept consistent, and the four lifting holes are distributed in a rectangular shape on the hanging plate, which improves the stability of the device during lifting.

[0015] Furthermore, the connecting plate section is provided with a plurality of weight-reducing long holes arranged at intervals.

[0016] Beneficial effects: The connecting plate section is provided with a plurality of weight-reducing long holes arranged at intervals, which reduces the weight of the device, saves materials and facilitates installation and lifting.

[0017] Furthermore, the linear drive component is a hydraulic cylinder, and the piston rod end of the hydraulic cylinder is connected to the sliding plate segment.

[0018] Beneficial Effects: The hydraulic cylinder can provide greater force than electrical or pneumatic systems, facilitating the driving of the fixed seat.

[0019] Furthermore, the hydraulic cylinder and the overhead crane are both connected to a controller.

[0020] Beneficial effects: The controller controls the actions of the hydraulic cylinder and the overhead crane, eliminating the need for manual control of the hydraulic cylinder and the overhead crane, saving manpower, improving the degree of automation of the device, and improving work efficiency.

The left fixed base 1 and the right fixed base 2 have identical structures and are symmetrically arranged on the left and right sides of the hanging plate 3. In this embodiment, the left fixed base 1 is used as an example for detailed description. In this embodiment, for ease of description, the length direction of the hanging plate 3 is defined as the left-right direction, the width direction as the front-to-back direction, and the height direction as the up-down direction.

[0031] like Figure 1 and Figure 3 As shown, the left fixed seat 1 includes a placement seat section 9, a connecting plate section 8, and a sliding plate section 7 that are interconnected and distributed from bottom to top. The placement seat section 9 is provided with six placement slots 11 that are evenly spaced in the front-to-back direction. The placement slots 11 extend in the left-right direction. The placement slot 11 has two parallel and vertically arranged side walls, two clamping slot walls that are inclined in opposite directions and have a set angle in the inclined direction. The clamping slot walls correspond to the side walls one-to-one and are connected to the bottom of the corresponding side walls. The distance between the two side walls is greater than the diameter of the cast iron pipe. The cast iron pipe is placed on the clamping slot walls to facilitate clamping the cast iron pipe. A limit plate 12 is provided on the outside of the placement slot 11 relative to the hanging plate 3 to prevent the cast iron pipe from sliding out of the placement slot 11 when the cast iron pipe is hoisted. The connecting plate section 8 connects the placement seat section 9 and the sliding plate section 7. The connecting plate section 8 is provided with five weight-reducing long holes 10 arranged at equal intervals in the left and right directions. The setting of the weight-reducing long holes 10 can reduce the weight of the device, save materials and facilitate installation and lifting.

[0032] like Figure 1 and Figure 2As shown, a sliding cavity extending in the left-right direction is provided within the hanging plate 3. A support plate 6 is provided in the middle of the sliding cavity, dividing the sliding cavity into two chambers. Sliding plate segments 7 are located in corresponding chambers. Two linear drive members spaced apart in the front-to-back direction are connected to either side of the support plate 6. In this embodiment, the linear drive members are hydraulic cylinders 5, the piston rod ends of which are connected to the sliding plate segments 7. The hydraulic cylinders 5 drive the sliding plate segments 7 to slide within the corresponding chambers. In other embodiments, the linear drive members may also be electric push rods, the output ends of which are connected to the sliding plate segments 7.

[0033] like Figure 1 and Figure 2 As shown, the hanging plate 3 is provided with four rectangularly distributed lifting holes 4. Steel cables are connected between the lifting holes 4 and the overhead crane for lifting the device.
