DETAILED DESCRIPTION
[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0025] Reference Figure 1 and Figure 2As shown, the utility model discloses a stacker guide device, comprising a support 10 and a guide mechanism.
[0026] The support 10 is used to connect the guide mechanism and the stacker; specifically, the support 10 is connected to the crossbeam of the stacker. A guide rail 11 is provided on one side of the support 10; preferably, the guide rail 11 is provided at the bottom of the support 10.
[0027] Preferably, two guide mechanisms are provided on the same support 10, and the two guide mechanisms are respectively arranged on both sides perpendicular to the extension direction of the guide rail 11 to ensure stability during the guiding process; at the same time, the installation space is sufficient and easy to install and maintain. The guide mechanism includes a guide wheel assembly 20, a mounting seat 30 and two sets of elastic components 40.
[0028] The guide wheel assembly 20 includes a guide wheel shaft 21 and a guide wheel 22. The guide wheel shaft 21 is connected to the mounting seat 30. The guide wheel 22 is connected to the guide wheel shaft 21 and can rotate. The specific rotation connection between the guide wheel 22 and the guide wheel shaft 21 can be set according to actual needs, such as setting a bearing, etc. Preferably, the axial direction of the guide wheel shaft 21 is perpendicular to the extension direction of the guide rail 11.
[0029] Two groups of elastic components 40 are respectively arranged on both sides of the radial direction of the guide wheel shaft 21, and each group of elastic components 40 includes two elastic units 41, and the two elastic units 41 are arranged in sequence along the axial direction of the guide wheel shaft 21; wherein, the mounting seat 30 is elastically connected to the support 10 through the elastic unit 41, so that the wheel surface of the guide wheel 22 abuts against the guide rail 11. The elastic unit 41 is a prior art, and those skilled in the art can set it according to actual needs, which will not be repeated. When each group of elastic components 40 is provided with only one elastic unit 41, it is difficult to cope with the force of rollover and the like; when each group of elastic components 40 is provided with three or more elastic units 41, the number of elastic units 41 is large, the installation is cumbersome, the weight of the device is increased, and the operating energy consumption is increased. When the elastic component 40 is only provided on one side of the radial direction of the guide wheel shaft 21, the effect is relatively poor. This structure can not only ensure that the wheel surface of the guide wheel 22 abuts against the guide rail 11 to achieve guidance under normal circumstances, but also effectively alleviate the lateral force on the guide wheel 22 and the guide rail 11 during actual use, avoid excessive squeezing between the guide wheel 22 and the guide rail 11, and reduce the shearing of bolts or the fracture of the ground rail welding during the operation of the stacker. At the same time, it can also reduce the wear rate of the guide wheel 22 and extend its service life. It effectively reduces the workload of the staff for maintenance and the production and maintenance costs.
[0030] The stacker guide device described in the utility model can not only achieve guidance by setting a guide mechanism, but also effectively alleviate the lateral force on the guide wheel 22 and the guide rail 11 during actual use, avoid excessive squeezing between the guide wheel 22 and the guide rail 11, and reduce the situation of bolt shearing or ground rail welding fracture during the operation of the stacker. At the same time, it can also reduce the wear rate of the guide wheel 22 and extend its service life. It effectively reduces the workload of the staff for maintenance and the production and maintenance costs. It is particularly suitable for use in stackers with a height of more than 25m and a cargo load of more than 1.5t.
[0031] Reference Figure 3 As shown, in the stacker guide device of the utility model, in some embodiments, the elastic unit 41 includes a mounting shaft 411 and a spring 412. The mounting shaft 411 is axially movable and connected to the mounting seat 30. The mounting shaft 411 is located at one end of the mounting seat 30 away from the support 10 and is provided with an abutment portion 4111. The spring 412 is sleeved on the mounting shaft 411, and one end of the spring 412 abuts against the abutment portion 4111, and the other end of the spring 412 abuts against the mounting seat 30. Compared with the case where the spring 412 is arranged on the side of the mounting shaft 411 away from the support 10 away from the mounting seat 30, the elastic unit 41 of this structure can be well adapted to the guide rail 11, effectively alleviate the lateral force on the guide wheel 22 and the guide rail 11 during actual use, avoid excessive extrusion between the guide wheel 22 and the guide rail 11, and reduce the situation of bolt shearing or ground rail welding fracture during the operation of the stacker. At the same time, it can also reduce the wear rate of the guide wheel 22 and extend its service life; effectively reduce the workload of the staff for maintenance, and facilitate maintenance by the staff. It should be noted that those skilled in the art can adjust the specifications of the spring 412 and the mounting shaft 411 according to the actual stacker height and load requirements. Preferably, the spring 412 is configured as a rectangular spring, which has the advantages of small size, good elasticity, high hardness, high rigidity, and long service life. It does not have very high requirements on the mounting surface and has a simple processing technology.
[0032] Furthermore, in some embodiments of the stacker guide device of the utility model, the end of the installation shaft 411 away from the abutment portion 4111 can be detachably connected to the support 10. By detachably connecting the installation shaft 411 and the support 10, it is convenient for the staff to assemble and repair, and the workload of the staff is effectively reduced. A specific detachable method can be set according to actual needs, such as threaded connection, clamping, etc.
[0033] Further, see Figure 2 and Figure 3As shown, in the stacker guide device described in the utility model, in some embodiments, the elastic unit 41 also includes a latch component 413 and a mounting nut 414; the mounting shaft 411 is threadedly connected to the support 10; the mounting shaft 411 is located at the end of the support 10 away from the mounting seat 30 and is provided with a latch hole 4112, the latch component 413 is inserted into the latch hole 4112, the mounting nut 414 is connected to the mounting shaft 411, and the mounting nut 414 is arranged between the latch component 413 and the support 10. Through this structure, on the one hand, it is effective to ensure firm assembly and avoid the occurrence of loosening and falling off during use; on the other hand, it is convenient for the staff to carry out maintenance and reduce their workload. Preferably, the latch is set as a cotter pin.
[0034] Reference Figure 4 As shown, in the stacker guide device of the utility model, in some embodiments, an oil guide channel 211 is provided on the guide wheel shaft 21, and the oil guide channel 211 is connected to the guide wheel 22. The oil guide channel 211 is provided to facilitate the injection of lubricating oil into the guide wheel 22 through the oil guide channel 211, so that the guide wheel 22 can rotate more smoothly. At the same time, the guide wheel shaft 21 is also formed into a hollow structure, which reduces weight and improves bending resistance.
[0035] Further, see Figure 4 As shown, in some embodiments of the stacker guide device described in the utility model, the guide wheel 22 is set as a roller bearing, and a cylindrical roller 222 is provided between the inner ring 223 and the outer ring 221 of the roller bearing, and an oil guide hole 2231 is opened on the side wall of the inner ring 223, and the oil guide hole 2231 is connected to the cylindrical roller 222 and the oil guide channel 211 respectively. The guide wheel 22 is set as a roller cylindrical roller bearing, which can withstand a larger radial load. The roller cylindrical roller bearing belongs to the prior art, and those skilled in the art can set its specific specifications according to actual needs, and will not be repeated.
[0036] Reference Figure 4 As shown, in the stacker guide device of the utility model, in some embodiments, two locking nuts 212 are sequentially sleeved on the end of the guide wheel shaft 21 located at the mounting seat 30 away from the guide wheel 22. The two locking nuts 212 can effectively prevent the guide wheel shaft 21 from loosening and the guide wheel 22 from falling during use.
[0037] Reference Figure 5 As shown, the stacker guide device of the utility model, in some embodiments, further includes a brush component 51, the brush component 51 is connected to the support 10, and the bristles of the brush component 51 abut against the guide rail 11. The brush component 51 can clean the guide rail 11 during the operation of the stacker.
[0038] Reference Figure 3As shown, in some embodiments of the stacker guide device of the utility model, a gasket 31 is provided between the mounting seat 30 and the support 10. By providing the gasket 31, the gasket 31 can be adjusted according to the size of the actual guide rail 11 during actual use, so that the device can adapt to the commonly used model of the guide rail 11; in addition, the requirements for the mounting surface between the mounting seat 30 and the support 10 are also reduced, the processing technology is simple, and the production cost is low.
[0039] The utility model discloses a stacker, comprising the stacker guide device described in any one of the above embodiments. Since the stacker of the utility model comprises the stacker guide device described in the above embodiments, the stacker also has all the beneficial effects, which will not be described in detail.
[0040] Working principle:
[0041] When the stacker runs along the guide rail 11, the mounting shaft 411 cooperates with the spring 412 to ensure that the wheel surface of the guide wheel 22 abuts against the guide rail 11. When a large lateral force is caused between the guide wheel 22 and the guide rail 11 due to reasons such as unevenness of the side of the guide rail 11 and deformation of the crossbeam of the stacker, the lateral force is relieved under the cooperation of the mounting seat 30, the spring 412 and the mounting shaft 411, etc., to avoid excessive squeezing between the guide wheel 22 and the guide rail 11, thereby reducing the situation of bolt shearing or fracture of the ground rail welding during the operation of the stacker.
[0042] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
