[0019] The beneficial effects of this utility model are:
[0020] This utility model provides a steel receiving trolley device for a cooling bed, comprising a crossbeam, a trolley, a trolley roller mechanism, and a chain drive assembly. The trolley is movably mounted on the top bearing surface of the crossbeam along its length. At least one roller groove extending along the length of the crossbeam is provided on each of the two sides of the crossbeam. At least one trolley roller mechanism is mounted on each of the two sides of the trolley. The trolley roller mechanism includes a roller mounting plate and at least one roller.

[0032] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0033] like Figures 1-7As shown, one embodiment of the present invention provides a steel receiving trolley device for a cooling bed, including a crossbeam 1, a trolley 2, a trolley roller mechanism 201 and a chain drive assembly. The trolley 2 is movably mounted on the top bearing surface of the crossbeam 1 along the length direction of the crossbeam 1. At least one roller groove 101 extending along the length direction of the crossbeam 1 is respectively provided on the two sides of the crossbeam 1.
[0034] At least one trolley roller mechanism 201 is installed on each of the two sides of the trolley 2. The trolley roller mechanism 201 includes a roller mounting plate 207 and at least one roller 208. The roller mounting plate 207 is fixed to the side of the trolley 2 and extends to one side of the crossbeam 1. The roller 208 is installed on the side of the roller mounting plate 207 facing the crossbeam 1, and the roller 208 rolls in contact with the roller groove 101.
[0035] The chain drive assembly is used to drive the trolley 2 to move back and forth along the length of the crossbeam 1.
[0036] In this embodiment, when the steel receiving trolley device on the cooling bed is working, the chain drive assembly drives the trolley 2 to move along the length of the crossbeam 1, and the rollers 208 in the trolley roller mechanism 201 on the side of the trolley 2 roll along the roller grooves 101 on the side of the crossbeam 1. Since the roller mounting plates 207 limit the trolley 2 from both sides of the crossbeam 1, and the rollers 208 are embedded in the roller grooves 101 on the side of the crossbeam 1, it is ensured that the trolley 2 will not tilt when moving, thus ensuring the stability of the trolley 2 during movement. Compared with using cards attached to the side of the crossbeam 1 to ensure the stability of the trolley 2 during movement, this embodiment has at least the following advantages: First, it can effectively prevent the trolley 2 from tilting, ensuring that the trolley 2 runs smoothly and will not collide with other parts of the cooling bed due to tilting, resulting in steel shifting and falling off. Second, the trolley roller mechanism 201 has a long service life.
[0037] As can be seen, in this embodiment, the trolley roller mechanism 201 is used to replace the previous card, thereby extending the service life of the trolley 2, effectively preventing the trolley 2 from tilting, and ensuring the smooth operation of the trolley 2.
[0038] It should be noted that the crossbeam 1 is installed on the main crossbeam of the cooling bed unloading device to support the weight of the trolley 2 and the conveying bar. As part of the transmission system, it plays a load-bearing role and ensures the overall stability of the trolley 2.
[0039] As a specific example, such as Figure 2 and Figure 3As shown, the trolley 2 includes two parallel main boards, namely a first main board 202 and a second main board 203. Two connecting plates 205 are fixedly installed between the first main board 202 and the second main board 203, respectively located on the left and right sides of the main boards. Each connecting plate 205 has at least one mounting hole. Furthermore, multiple fixing plates 204 are fixedly installed between the first main board 202 and the second main board 203. The fixing plates 204 are located between the two connecting plates 205 and are arranged along the length of the main boards. The fixing plates 204 serve to connect the first main board 202 and the second main board 203, thereby improving the structural strength of the trolley 2.
[0040] Preferred, such as Figure 4 and Figure 5 As shown, the top of the roller mounting plate 207 has multiple countersunk holes 210. The first main plate 202 and the second main plate 203 of the trolley 2 have multiple bolt holes 206 corresponding to the countersunk holes 210. A wheel axle is fixedly installed at the bottom of the roller mounting plate 207 by a fixing pin 209. The wheel axle is perpendicular to the roller mounting plate 207. A bearing is installed on the wheel axle. The roller 208 and the outer ring of the bearing are connected.
[0041] It should be noted that the roller mounting plate 207 is fixedly mounted to the trolley 2 with bolts. Specifically, the roller mounting plate 207 is attached to the main plate of the trolley 2, with the countersunk hole 210 on the roller mounting plate 207 aligned with the bolt hole 206 on the main plate. Then, the countersunk bolt is passed through the countersunk hole 210 at the top of the roller mounting plate 207 and tightened until it is screwed into the bolt hole 206 on the main plate. This facilitates the subsequent disassembly of the trolley 2 and the trolley roller mechanism 201, making it easier to maintain and replace the trolley roller mechanism 201.
[0042] For example, such as Figure 1 As shown, two trolley roller mechanisms 201 are installed on the outer sides of both the first main board 202 and the second main board 203, for a total of four trolley roller mechanisms 201. These two trolley roller mechanisms 201 are arranged along the moving direction of the trolley 2. This ensures that the trolley 2 moves more stably on the crossbeam 1, preventing it from tipping over. Of course, the number of trolley roller mechanisms 201 on each main board can be reasonably set according to the actual situation.
[0043] In the past, chain drive assemblies relied solely on tensioning devices, i.e., tensioners, to adjust the tension of chain 4 in order to prevent chain 4 from being too loose or too tight and affecting the transmission effect. However, tensioners cannot precisely adjust the tension of chain 4.
[0044] In this embodiment, as Figure 1As shown, the chain drive assembly includes a drive sprocket 5, a driven sprocket 6, and a chain 4. The drive sprocket 5 is rotatably mounted on the left end of the crossbeam 1, and the driven sprocket 6 is rotatably mounted on the right end of the crossbeam 1. The chain 4 is not a loop-shaped closed chain, but a long strip-shaped chain 4. The chain 4 is wound between the drive sprocket 5 and the driven sprocket 6, and one end of the chain 4 is connected to the connecting plate 205 on the left side of the trolley 2 through an adjusting screw assembly 3. The other end of the chain 4 is connected to the connecting plate 205 on the right side of the trolley 2 through an adjusting screw assembly 3. The adjusting screw assembly 3 is used to adjust the tension of the chain 4.
[0045] Specifically, the adjusting screw assembly 3, such as Figure 6 As shown, it includes a screw 303, a pin block 301, and at least one nut 304. Figure 7 This diagram shows the connection relationship between the chain 4, the adjusting screw assembly 3, and the connecting plate 205. As can be seen from the diagram, the pin block 301 has a pin hole 302, through which the pin block 301 is hinged to the pin of the chain 4. The end of the screw 303 passes through the mounting hole on the connecting plate 205. Two nuts 304 are provided, screwed onto the end of the screw 303, and located on the left and right sides of the connecting plate 205 respectively.
[0046] When fine-tuning the tension of chain 4, first turn... Figure 7 The nut 304 located on the right side of the connecting plate 205 is moved a certain distance to the right, so that the nut 304 on the right side of the connecting plate 205 is no longer tightly attached to the connecting plate 205. Then, the nut 304 located on the left side of the connecting plate 205 is tightened, so that the screw 303 moves a certain distance to the left. The operator observes the tension of the chain 4 at this time. If the tension is appropriate, the nut 304 located on the right side of the connecting plate 205 is tightened, so that the nut 304 on the right side of the connecting plate 205 is tightly attached to the connecting plate 205.
[0047] Therefore, the tension of the chain 4 can be finely adjusted using the adjusting screw assembly 3. Moreover, since the adjusting screw assembly 3 can be disassembled at any time, installation and disassembly are more convenient and quick, and maintenance of the chain 4 is also easier.
[0048] In a preferred embodiment, to prevent the chain 4 from running unstablely and deviating from the predetermined track, this embodiment solves the problem from the following two aspects: First, a chain guide groove 10 extending along the length direction of the crossbeam 1 is provided on the upper surface of the crossbeam 1. The chain 4 is always within the chain guide groove 10, which can ensure to a certain extent that the chain 4 always runs along the predetermined track and prevent the chain 4 from deviating or jumping.
[0049] Second, two vertical plates are fixedly installed on the lower surface of the crossbeam 1, and a chain guide wheel 9 is rotatably installed on each vertical plate. The chain 4 is connected to the two chain guide wheels 9. The chain guide wheels 9 help the chain 4 run on a specific path, prevent the chain 4 from deviating from the predetermined track, help maintain the straight running of the chain 4, and reduce the twisting and swaying of the chain 4.
[0050] It is evident that by employing the two methods described above, it is possible to effectively prevent chain 4 from deviating from the predetermined track, help maintain the straight-line operation of chain 4, and reduce the twisting and swaying of chain 4.
[0051] In addition, multiple beam bases 8 are installed on the lower surface of the beam 1 to support it. The beam bases 8 and the beam 1 together form a stable structural system, improving the overall seismic performance of the structure.
[0052] Furthermore, it should be noted that in this embodiment, the trolley roller mechanism 201 bears the trolley 2 and its load, distributing the weight evenly across each roller 208, ensuring stable and reliable operation of the trolley 2. Alternatively, the trolley 2 can act on the crossbeam 1, with the trolley roller mechanism 201 not bearing any load. Both methods have their advantages, which will not be elaborated upon here.
