Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe hot rolling equipment, in particular to a mandrel cooling dialing and supporting device. Background Art

[0002] At present, in the production process of seamless steel pipes, after the rough pipe is rolled on the pipe rolling mill, it enters the rod stripping machine to remove the core rod. After the core rod is removed from the rough pipe, it enters the cooling pool for cooling. The existing set of material dispensing and supporting mechanisms is to fix multiple material dispensing hooks and supporting hooks on two sets of material dispensing shafts respectively. Each set of material dispensing shafts is composed of three shafts, and the shafts are connected with sleeve bevel keys. The two sets of material dispensing shafts are fixed on the pool mounting plate through multiple double-hole bearing seats at the same time. The double-hole bearing seat fixing bolts are connected into one from the bottom of the bearing seat and the upper cover. A cylinder drives a set of material dispensing shafts to rotate, and the core rod is transferred from the roller to the supporting hook. The other two cylinders drive another set of material dispensing shafts to rotate and transfer the core rod on the supporting hook into the cooling water pool for cooling. During daily use, the core rod with a larger outer diameter is pushed from the material-pushing hook into the supporting hook with a large impact force, which often causes the supporting hook to wear, become loose, or break, and the connecting bolts of the double-hole bearing seat become loose and damaged. The entire set of material-pushing and supporting mechanism needs to be disassembled and replaced, which is inconvenient for maintenance. The site urgently needs a set of simple structure, easy maintenance, stable and reliable dial-in and supporting hook device. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and to provide a core rod cooling dial-in and supporting device which has a simple structure, is easy to install and maintain, and can effectively save troubleshooting time.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A core rod cooling device includes a loading mechanism and a taking mechanism, wherein:

[0006] The feeding mechanism comprises a feeding arm assembly, a feeding shaft, a single-hole bearing seat and a feeding drive assembly; the feeding shaft extends along a first direction and is mounted on a water pool mounting plate through a single-hole bearing seat, the feeding arm assembly comprises a plurality of feeding arms fixed to the feeding shaft at intervals along the first direction, and the feeding arm extends along a second direction, the feeding arm assembly has a first station and a second station, when the feeding arm assembly is in the first station, it is used to receive the core rod transferred by the material taking mechanism, and when the feeding arm assembly is in the second station, it is used to transport the received core rod into the water pool; the output end of the feeding drive assembly is connected to the feeding shaft, and when it is in action, it drives the feeding shaft to rotate, so as to drive the feeding arm assembly to switch between the first station and the second station;

[0007] The feeding mechanism includes a feeding arm assembly and a feeding drive assembly; the feeding arm assembly includes a plurality of feeding arms spaced apart along a first direction, one end of each feeding arm being sleeved on a feeding shaft, and each feeding arm being relatively fixed, and the other end of each feeding arm being away from the feeding arm; the feeding arm assembly has a first station and a second station; when the feeding arm assembly is in the first station, it is used to pick up a core rod; when the feeding arm assembly is in the second station, it is used to transfer the core rod to the feeding arm assembly by its own gravity through rolling; the output end of the feeding drive assembly is connected to the feeding arm assembly to drive the feeding arm assembly to switch between the first station and the second station. Through this arrangement, the feeding hooks and support hooks on the original two sets of feeding shafts are reduced to one set of feeding shafts, the overall structure is simple, and the feeding shaft can be installed on the sink mounting plate through a single-hole bearing seat, which is convenient to install and maintain, can effectively save troubleshooting time, and improve production efficiency.

[0008] Furthermore, the feeding drive assembly includes a feeding cylinder and a swing arm; the output end of the feeding cylinder is connected to the first end of the swing arm, and the second end of the swing arm is connected to the feeding shaft to realize the rotation of the feeding shaft. With this arrangement, the feeding cylinder drives the swing arm to swing, thereby driving the feeding shaft to rotate, so that the feeding arm fixedly connected to the feeding shaft switches between the first and second positions, and realizes receiving the mandrel transferred by the material removal mechanism and transporting the received mandrel into the water tank.

[0009] Furthermore, there are two sets of feeding drive assemblies, one at each end of the feeding shaft. By providing two sets of feeding drive assemblies, one at each end of the feeding shaft, the load-bearing capacity of the feeding shaft and feeding arm can be guaranteed, deformation of the feeding shaft can be prevented, and each feeding arm can be kept at the same height.

[0010] Furthermore, the invention further comprises a first cylinder support, wherein two first cylinder supports are respectively located at the two ends of the feeding shaft, and the feeding cylinder is correspondingly mounted on the first cylinder support. Through this arrangement, the installation stability of the first cylinder can be improved.

[0011] Furthermore, the fetching arm assembly further includes a connecting rod; the connecting rod extends along the first direction, and each of the fetching arms is connected to the connecting rod to achieve relative fixation between the fetching arms.

[0012] Furthermore, the retrieving drive assembly includes a retrieving cylinder; the output end of the retrieving cylinder is connected to the end of at least one retrieving arm away from the loading shaft to drive the retrieving arm assembly to switch between the first and second workstations. With this arrangement, the retrieving cylinder drives the retrieving shaft, resulting in a simple structure and low cost.

[0013] Furthermore, the system includes a second cylinder support located in the middle of the connecting rod. The pick-up cylinder is mounted on the second cylinder support and connected to the pick-up arm located in the middle of the connecting rod. This arrangement connects the pick-up cylinder to the middle pick-up arm, reducing the number of pick-up cylinders used and reducing costs. It also enables the pick-up arm assembly to maintain balance during operation, preventing the mandrel from slipping.

[0014] Furthermore, the connecting rod is a hollow steel pipe. This arrangement can reduce the weight of the connecting rod and reduce the load on the material taking cylinder.

[0015] Furthermore, the loading arm and the taking arm are alternately arranged along the axial direction of the loading shaft. Through this arrangement, the loading arm and the taking arm will not affect each other when working.

[0016] Furthermore, the feeding shaft is one or multiple feeding shafts connected by a coupling. With this arrangement, the feeding shaft is one or multiple feeding shafts connected by a coupling, and under the impact of a core rod with a larger outer diameter, there will be no misalignment, and the feeding arm will not be uneven, causing the core rod to tilt after entering the water tank, and other problems will not occur.

[0017] The utility model has the following advantages over the prior art:

Its overall structure is simple. The feeding hooks and supporting hooks on the original two sets of feeding shafts are reduced to one set of feeding shafts. Only one set of feeding shafts is needed to realize the functions of feeding and discharging at the same time. Moreover, the feeding shaft in the present invention only needs a single-hole bearing seat to be installed on the water tank mounting plate. Compared with the double-hole bearing seat in the prior art, the single-hole bearing seat of the present application is easy to install and maintain, which can effectively save troubleshooting time and improve production efficiency.

[0019] 2. The feeding shaft in the present invention is one or multiple shafts connected by a coupling. Compared with the prior art in which the shafts are connected by a sleeve bevel key, the coupling has high stability. When a core rod with a larger outer diameter falls off the feeding arm, each feeding shaft is relatively fixed by the coupling, which is not easy to be misaligned, and the feeding arm is not easy to be uneven, causing the core rod to tilt after entering the water pool.

[0029] Example:

[0030] like Figures 1 to 4As shown, the utility model provides a core rod cooling dial-in and supporting device, including a feeding mechanism 1 and a picking mechanism 2, wherein: the feeding mechanism includes a feeding arm assembly, a feeding shaft 101, a single-hole bearing seat 102 and a feeding drive assembly; the feeding shaft 101 extends along a first direction X and is mounted on a pool mounting plate 3 through a single-hole bearing seat 102, the feeding arm assembly includes a plurality of feeding arms 103 fixed to the feeding shaft 101 at intervals along the first direction, and the feeding arm 103 extends along a second direction The loading arm assembly has a first station and a second station. When the loading arm assembly is in the first station, it is used to receive the core rod transferred by the picking arm 201 of the picking mechanism 2. When the loading arm assembly is in the second station, it is used to transport the received core rod into the water pool 4. The output end of the loading drive assembly is connected to the loading shaft 101. When it is in action, it drives the loading shaft 101 to rotate, thereby driving the loading arm 103 to rotate around the loading shaft, so as to realize the switching of the loading arm assembly between the first station and the second station.

[0031] The retrieving mechanism 2 includes a retrieving arm assembly and a retrieving drive assembly. The retrieving arm assembly includes a plurality of retrieving arms 201 spaced apart along a first direction. One end of each retrieving arm 201 is sleeved on the loading shaft 101, and each retrieving arm 201 is relatively fixed to each other. The other end of each retrieving arm 201 is away from the loading arm 103. The retrieving arm assembly has a first station and a second station. When the retrieving arm assembly is in the first station, it is used to pick up the mandrel on the roller 6. When the retrieving arm assembly is in the second station, it is used to transfer the mandrel to the loading arm assembly by its own gravity. The output end of the retrieving drive assembly is connected to the retrieving arm assembly to drive the retrieving arm assembly to switch between the first station and the second station. The retrieving arm 201 is only sleeved on the loading shaft 101. The rotation of the loading shaft 101 does not drive the retrieving arm 201 to move. The retrieving arm 201 is driven by the retrieving drive assembly, and each retrieving arm 201 moves synchronously. The loading arms 103 and the retrieving arms 201 are arranged alternately along the axis of the loading shaft 101. This arrangement prevents the loading arms 103 and the retrieving arms 201 from interfering with each other during operation. In this embodiment, the feeding hooks and support hooks on the original two sets of feeding shafts are reduced to a single set of feeding shafts, resulting in a simple overall structure. The feeding shaft 101 can be mounted on the tank mounting plate via a single-hole bearing seat 102, making installation and maintenance easy, effectively reducing troubleshooting time and improving production efficiency.

[0032] like Figure 3As shown, the feeding drive assembly includes a feeding cylinder 104 and a swing arm 105; the output end of the feeding cylinder 104 is connected to the first end of the swing arm 105, and the second end of the swing arm 105 is fixedly connected to the feeding shaft 101. The feeding cylinder 104 pushes the swing arm 105 to swing, thereby driving the feeding shaft 101 to rotate so that the feeding arm fixedly connected to the feeding shaft switches between the first station and the second station, thereby receiving the mandrel transferred by the material removal arm 201 and transporting the received mandrel into the water tank. Specifically, the feeding drive assembly also includes a first cylinder support 106, and the feeding cylinder 104 is fixedly mounted on the first cylinder support 106 via a pin 7. Through this arrangement, the installation stability of the first cylinder 104 can be improved.

[0033] Preferably, there are two sets of feeding drive assemblies, one at each end of the feeding shaft 101. Specifically, first cylinder supports 106 are provided at corresponding positions at each end of the feeding shaft 101. The feeding cylinder 104 is mounted via the first cylinder supports 106, and the output end of the feeding cylinder 104 is connected to the feeding arms 103 at each end of the feeding shaft 101 via swing arms 105. By providing two sets of feeding drive assemblies, one at each end of the feeding shaft, the load-bearing capacity of the feeding shaft and feeding arms can be guaranteed, deformation of the feeding shaft 101 under load can be prevented, and each feeding arm 103 can be kept at the same height.

[0034] In this embodiment, the retrieving arm assembly further includes a connecting rod 202 extending in a first direction. The connecting rod 202 connects the retrieving arms 201 to each other, thereby securing the retrieving arms 201 relative to each other. Driven by the retrieving cylinder, the retrieving arms 201 operate synchronously. Preferably, the connecting rod 202 is a hollow steel tube. This configuration reduces the weight of the connecting rod and the load-bearing capacity of the retrieving cylinder.

[0035] like Figure 4 As shown, the retrieving drive assembly includes a retrieving cylinder 203; the output end of the retrieving cylinder 203 is connected to the end of at least one retrieving arm 201 away from the loading shaft 101, thereby driving the retrieving arm assembly to switch between the first and second workstations. This arrangement utilizes the retrieving cylinder 203 to drive the retrieving arm 201, resulting in a simple structure and low cost.

[0036] It also includes a second cylinder support 204, which is located in the middle of the connecting rod 202. The feeding cylinder 203 is installed on the second cylinder support 204 through the pin 7 and is connected to the feeding arm 201 located in the middle of the connecting rod 202. Through this arrangement, the feeding cylinder 203 is connected to the feeding arm 201 in the middle, which reduces the number of feeding cylinders 203 used and reduces costs. At the same time, it can keep the feeding arm assembly balanced during the working process and prevent the core rod from slipping. The feeding arm located in the middle of the connecting rod is provided with a fixing ring 205 at its bottom, which is connected to the output end of the feeding cylinder 203 through the fixing ring 205.

[0037] In this embodiment, the feeding shaft 101 is one or multiple feeding shafts connected by a coupling 5. In the prior art, the feeding shafts are connected by a sleeve key, which has weak connection stability. When a mandrel with a larger outer diameter falls from the take-up arm to the feeding arm, the feeding shafts connected by the sleeve key are impacted and misaligned, causing the feeding arm to become uneven and causing the mandrel to tilt after entering the water tank. In this embodiment, the feeding shaft 101 is one or three feeding shafts, which are tightly connected by a coupling 5. Even under the impact of a mandrel with a larger outer diameter, the feeding shafts will not become misaligned, and will not cause the feeding arm to become uneven and cause the mandrel to tilt after entering the water tank.

[0038] When working:

[0039] The retrieving cylinder in the retrieving mechanism actuates, driving the retrieving arm to rotate around the loading shaft, removing the mandrel from the roller conveyor. The retrieving cylinder in the loading mechanism actuates, driving the loading shaft to rotate, thereby rotating the loading arm connected to the loading shaft, positioning the loading arm in the first position, ready to receive the mandrel transferred by the retrieving arm. The retrieving cylinder continues to actuate, causing the mandrel to roll down to the loading arm under its own gravity. After receiving the mandrel, the loading cylinder of the loading mechanism continues to actuate, causing the loading arm to rotate, thereby transferring the mandrel received by the loading arm into the water tank. The utility model is characterized in that a set of loading shafts simultaneously realizes the functions of material discharging and discharging, resulting in a simple structure and easy maintenance.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
