Description

Technical Field

[0001] This utility model relates to the field of aluminum coil manufacturing technology, and in particular to an aluminum coil temperature measuring device suitable for stacker cranes. Background Technology

[0002] Aluminum coils that have passed through cold rolling mills, hot rolling mills, annealing furnaces, and finishing equipment need to be transported by stacker cranes to high-bay warehouses for storage, or, depending on subsequent processes, the aluminum coils can be retrieved from the warehouse by stacker cranes and then transported to the appropriate processing equipment. Figure 1 As shown in the picture, the aluminum coil is placed on the saddle of the stacker crane. There are protective frames on both sides of the saddle to prevent the aluminum coil from rolling.

[0003] On the one hand, the aluminum coils coming off the equipment have different temperatures when they enter the warehouse due to different processes. Coils with different temperatures are stored in different locations in the high-bay warehouse. Coils with high temperatures need to be placed in the strong cooling zone of the warehouse for rapid cooling, while aluminum coils with low temperatures need to be placed in the regular cooling zone of the warehouse for natural cooling.

[0004] On the other hand, the temperature requirements for aluminum coils stored in the warehouse vary depending on the subsequent processes, which in turn affects their storage time. For example, in the preceding processes, the temperature of aluminum coils coming off the hot rolling mill and annealing furnace is 300-350℃, while in the subsequent processes, the temperature requirement for the cold rolling mill and finishing equipment is below 80℃.

[0005] Therefore, it is clear that temperature control is necessary when aluminum coils are stored and removed from the warehouse. In daily production, aluminum coils coming off the machine require manual temperature measurement, which is then reported to warehouse management personnel. Based on the temperature, the management personnel store the coils. Sometimes, after temperature measurement, the coils are stored in order, resulting in them waiting outside the warehouse for extended periods. During this waiting period, the temperature may drop, making it impossible to determine the correct storage temperature. Consequently, it becomes impossible to allocate storage locations and calculate cooling times based on the entry temperature, leading to inefficient storage and circulation of aluminum coils in the high-bay warehouse.

[0006] When the aluminum coils are shipped out, a stacker crane needs to retrieve them from the warehouse, and then the temperature of the coils needs to be measured manually. Only when the temperature is below 80℃ can they be transferred to the equipment for rolling. If the temperature does not meet the requirements, they need to be returned to the warehouse for cooling, resulting in additional labor and equipment costs. Summary of the Invention

[0007] To address the problem of low efficiency in aluminum coil outbound and inbound operations due to the difficulty of manual real-time temperature measurement, this invention provides an aluminum coil temperature measuring device suitable for stacker cranes. By installing the temperature measuring device on the stacker crane, the temperature can be measured in real time when the stacker crane picks up and puts in aluminum coils, thereby enabling more rational allocation of aluminum coil storage locations and calculation of storage time, while also preventing invalid outbound aluminum coils.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A temperature measuring device for aluminum coils suitable for stacker cranes is installed on a protective frame on one side of the stacker crane. It includes a fixed bracket, a swing arm, a temperature detector, and an electronic cylinder. The fixed bracket is detachably mounted below the protective frame for easy installation of the entire temperature measuring device. The swing arm is rotatably connected to the upper part of the fixed bracket. The swing arm is bent into a sickle shape, passes around the protective frame, and extends vertically upwards. The temperature detector is mounted at the upper end of the swing arm. The electronic cylinder, used to drive the swing arm to swing, is hinged between the fixed bracket and the swing arm. The electronic cylinder is arranged below the swing arm.

[0009] Furthermore, the fixed bracket includes a horizontal bar and a vertical bar. The length direction of the horizontal bar is consistent with the length direction of the protective frame. The horizontal bar is bolted to the bottom of the protective frame. The vertical bar is set below the middle of the horizontal bar. The vertical bars are arranged at an angle. The cross section of the horizontal bar and the vertical bar after being connected and combined is "T" shaped.

[0010] Furthermore, a rotating plate is rotatably mounted on the crossbar. The rotating plate has a cross-section shaped like a "[". The swing arm is mounted on the rotating plate to facilitate rotation. The swing arm includes a sickle-shaped section bent into a sickle shape and a straight pipe section. One end of the sickle section is fixedly connected to the rotating plate, and the other end is fixedly connected to the straight pipe section. The straight pipe section and the sickle section are arranged vertically. The sickle section is designed to ensure that the swing arm avoids the protective frame, preventing the protective frame from interfering with the rotation of the swing arm.

[0011] Furthermore, the sickle segment includes two parallel curved plates spaced apart, with a reinforcing plate positioned between the two curved plates. The reinforcing plate is bent into an arc shape. The reinforcing plate improves the structural strength of the entire sickle segment.

[0012] Furthermore, a sensor support plate is provided at the upper end of the straight pipe section, and the temperature detector is bolted to the sensor support plate. The temperature detector is a contact temperature sensor, which facilitates direct contact with the aluminum coil for temperature measurement.

[0013] Furthermore, the lower end of the vertical rod is hinged to the electronic cylinder, and the telescopic end of the electronic cylinder is hinged upwards to the sickle section. This achieves the installation of the electronic cylinder.

[0014] Furthermore, an upper limit plate is provided on the upper side of the vertical rod, and an upper limit seat is provided on the sickle section. The upper limit seat abuts against the upper limit plate and restricts the swing arm from swinging downward. A lower limit seat is provided on the lower side of the vertical rod, and a lower limit frame is provided on the rotating plate. The lower limit frame abuts against the lower limit seat and restricts the swing arm from swinging upward.

[0015] The beneficial effects of this utility model through the above technical solution are: This invention is installed on a stacker crane. When the stacker crane picks up and places aluminum coils, it controls the swing arm to swing via an electronic cylinder. The swing arm drives a temperature detector to swing and contact the aluminum coil, thereby measuring the real-time temperature of the aluminum coil. This provides real-time temperature parameters for rationally allocating storage locations and calculating storage time for the aluminum coils. Furthermore, temperature is measured before outbound shipment, and shipment is only allowed if the conditions are met, avoiding ineffective outbound shipments, optimizing equipment operating efficiency, and saving equipment operating costs.

Detailed Implementation

[0025] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: like Figures 2-8As shown, an aluminum coil temperature measuring device suitable for a stacker crane is installed on a protective frame 102 on one side of the stacker crane 1. The temperature measuring device can move with the stacker crane 1, so that the temperature can be measured during the process of aluminum coil leaving and entering the warehouse.

[0026] The aluminum coil temperature measuring device includes a fixed bracket 2, a swing arm 3, a temperature detector 4, and an electronic cylinder 5. The fixed bracket 2 includes a horizontal bar 21 and a vertical bar 22. The horizontal bar 21 is a square tube structure, and its length direction is consistent with the length direction of the protective frame 102. The vertical bar 22 is set below the middle of the horizontal bar 21. The vertical bar 22 is also a square tube structure and is arranged at an angle. After the horizontal bar 21 and the vertical bar 22 are connected and combined, the cross section is "T" shaped.

[0027] The fixed bracket 2 is detachably installed below the protective frame 102. Specifically, the crossbar 21 is bolted to the bottom of the protective frame 102. Three lower mounting plates 6 are evenly welded above the crossbar 21, and three upper mounting plates 7 are evenly welded below the protective frame 102. The upper mounting plates 7 and lower mounting plates 6 correspond one-to-one. The cross section of the upper mounting plate 7 is "T". After the upper mounting plates 7 and lower mounting plates 6 are attached and fixed with bolts, the crossbar 21 can be installed below the protective frame 102.

[0028] A swing arm 3 is rotatably connected to the upper part of the fixed bracket 2. The swing arm 3 is bent into a sickle shape, passes around the protective frame 102, and extends vertically upward. The swing arm 3 includes a sickle-shaped section 31 and a straight pipe section 32. The other end of the sickle section 31 is connected and fixed to the straight pipe section 32. The straight pipe section 32 and the sickle section 31 are arranged vertically. Here, the sickle section 31 includes two parallel curved plates arranged at intervals. A reinforcing plate 8 is provided between the two curved plates. The reinforcing plate 8 is bent into an arc shape, which improves the structural strength of the sickle section 31.

[0029] During installation, a rotating plate 9 is rotatably mounted on the crossbar 21. Specifically, roller bearings 10 are symmetrically arranged on both sides of the crossbar 21, and the rotating plate 9 is welded between the two roller bearings 10. The rotating plate 9 has a cross-section in the shape of "[", and its two ends correspond to the roller bearings 10 respectively. The ends of the rotating plate 9 are welded and fixed to the outer rings of the roller bearings 10. The swing arm 3 is mounted on the rotating plate 9, and one end of the sickle section 31 of the swing arm 3 is connected and fixed to the rotating plate 9. Since the rotating plate 9 can rotate, the swing arm 3 can rotate together with it.

[0030] A temperature sensor 4 is installed at the upper end of the swing arm 3. During installation, a sensor support plate 11 is installed at the upper end of the straight pipe section 32, and the temperature sensor 4 is bolted to the sensor support plate 11. The temperature sensor 4 is a contact temperature sensor. The temperature sensor 4 is in direct contact with the aluminum coil to measure the temperature.

[0031] To drive the swing arm 3 to rotate and swing, an electronic cylinder 5 is hinged between the fixed bracket 2 and the swing arm 3. The electronic cylinder 5 is arranged below the swing arm 3, that is, the swing arm 3 and the electronic cylinder 5 are arranged vertically. During installation, the electronic cylinder 5 is hinged to the lower end of the vertical rod 22. Specifically, two bearing seats 12 are spaced apart at the lower end of the vertical rod 22. The cylinder of the electronic cylinder 5 is arranged between the two bearing seats 12. A lower hinge shaft 13 is inserted into each bearing seat 12. One end of the lower hinge shaft 13 is connected and fixed to the electronic cylinder 5. In this way, the electronic cylinder 5 can swing relative to the vertical rod 22.

[0032] The telescopic end of the electronic cylinder 5 is hinged upwards to the sickle section 31. Specifically, the telescopic end of the electronic cylinder 5 extends upwards between the two curved plates. An upper hinge shaft 14 is inserted between the two curved plates and the telescopic end of the electronic cylinder 5, so that the operation of the electronic cylinder 5 can drive the swing arm 3 to swing. The swing arm 3 swings at different amplitudes, which can drive the temperature detector 4 to adapt to the temperature measurement of aluminum coils of different diameters.

[0033] The principle of this invention is as follows: When aluminum coils are stored, the stacker crane 1 picks up the aluminum coil and places it on the saddle 101. At this time, the electronic cylinder 5 extends, driving the swing arm 3 to swing and the temperature detector 4 to approach the aluminum coil until it contacts it. The temperature detector 4 then feeds back a temperature signal, thus determining the real-time temperature of the aluminum coil. This provides temperature parameters for allocating the storage location of the aluminum coil and calculating the storage time. After the measurement is completed, the electronic cylinder 5 retracts, driving the swing arm 3 and the temperature detector 4 to reset. Similarly, the real-time temperature of the aluminum coil can also be measured and fed back during outbound storage, providing a basis for determining whether the aluminum coil meets the outbound conditions.

[0034] In order to optimize the product structure and limit the swing range of the swing arm 3, an upper limit plate 15 is provided on the upper side of the vertical rod 22, and an upper limit seat 16 made of rubber is provided on the sickle section 31. When the upper limit seat 16 presses down against the upper limit plate 15, the swing arm 3 can be restricted from swinging downward.

[0035] Meanwhile, a lower limit seat 17 is provided on the lower side of the vertical rod 22. The lower limit seat 17 has the same structure as the upper limit seat 16. A lower limit frame 18 is provided on the rotating plate 9, and the rotating plate 9 can drive the lower limit frame 18 to swing together. The lower limit frame 18 includes two side rods 181 bent into an "L" shape and a limiting rod 182 connecting the two side rods 181. One end of the side rod 181 passes downward over the horizontal rod 21 and is connected and fixed to the limiting rod 182. When the rotating plate 9 swings upward, the limiting rod 182 will swing downward. When the limiting rod 182 in the lower limit frame 18 presses down against the lower limit seat 17, the upward swing of the swing arm 3 can be restricted.

[0036] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
