Guiding mechanism and crane

Abstract

This application relates to a guiding mechanism and a crane. The guiding mechanism includes at least two sets of guiding units, which are respectively located on both sides of a slide rail. Each guiding unit includes a mounting member, a guiding member, and an elastic member. The mounting member is used to connect with the traveling mechanism of an electric hoist. The guiding member is disposed on the mounting member and is rotatable along a vertical axis. The elastic member is disposed between the guiding member and the mounting member and is used to press the guiding member towards the slide rail, so that the guiding member abuts against the slide rail. The two sets of guiding members in the two sets of guiding units can prevent the electric hoist traveling mechanism from moving in a second direction. By using the elastic member to ensure that the guiding members on both sides always abut against the slide rail, the position and distance of the electric hoist traveling mechanism relative to the slide rail are kept fixed, preventing the traveling mechanism from deviating along the second direction on the slide rail, thereby avoiding scraping or detachment of the electric hoist traveling mechanism from the slide rail.

Description

Technical Field

[0001] This application relates to the field of lifting equipment technology, and in particular to guiding mechanisms and cranes. Background Technology

[0002] An electric hoist crane is a type of lifting machinery that performs cyclical, intermittent movements. One work cycle includes: the lifting device raising the item from its location, moving it horizontally to a designated low point and lowering it, then reversing the movement to return the lifting device to its original position for the next cycle. Electric hoists are characterized by their small size, light weight, simple operation, and ease of use, and are used in industrial and mining enterprises, warehouses, docks, and other similar locations.

[0003] In related technologies, the horizontal movement of an electric hoist is achieved by the sliding of a traveling trolley on a slide rail. Specifically, the traveling trolley typically includes a sliding plate, wheels mounted on the sliding plate that slide on both sides of an I-shaped slide rail, and a drive motor mounted on the sliding plate that drives the wheels to rotate. The drive motor drives the wheels to rotate, causing the traveling trolley to move the electric hoist horizontally on the I-shaped slide rail.

[0004] However, in the aforementioned traveling trolley, the wheels experience a "grinding" phenomenon when moving, meaning that the wheels scrape against the I-shaped guide rail, causing wear on the wheels. At the same time, the wheels also shift, greatly reducing the stability of the traveling trolley. Summary of the Invention

[0005] Therefore, it is necessary to provide a guiding mechanism and a crane to address the problem that the wheels gnaw on the guide rails during travel, causing wear and misalignment of the wheels and greatly reducing the stability of the traveling trolley.

[0006] The first direction of this application provides a guiding mechanism, which is disposed on the traveling mechanism of an electric hoist. The traveling mechanism of the electric hoist is movably connected to a slide rail and can travel relative to the slide rail in a first direction. The guiding mechanism is used to guide the travel of the electric hoist traveling mechanism. The guiding mechanism includes at least two sets of guiding units, which are respectively located on both sides of the slide rail. Each set of guiding units includes a mounting member, a guiding member, and an elastic member. The mounting member is connected to the electric hoist traveling mechanism. The guiding member is disposed on the side of the mounting member facing the slide rail. The guiding member can rotate around a vertical axis and can follow the electric hoist traveling mechanism to move relative to the slide rail in the first direction. The elastic member is disposed between the guiding member and the mounting member. The elastic member provides the guiding member with an elastic force in a second direction, so that the guiding member abuts against the slide rail. The second direction, the first direction, and the vertical axis are all perpendicular to each other.

[0007] In one embodiment, the mounting member includes a first side plate and a second side plate disposed opposite to each other, both of which are provided with receiving grooves. The guide member includes a guide portion and a shaft portion, the shaft portion passing through the receiving groove, the guide portion being located between the first side plate and the second side plate, and being rotatably disposed on the shaft portion.

[0008] In one embodiment, the guide mechanism further includes a fixing member disposed in a receiving groove, and the shaft portion having a through hole through which at least a portion of the fixing member passes, allowing the shaft portion to move in a second direction.

[0009] In one embodiment, the elastic element is sleeved on the fixing element, with one end of the elastic element abutting against the wall of the receiving groove and the other end abutting against the shaft portion.

[0010] In one embodiment, the guide mechanism further includes a limiting member disposed on the shaft portion to prevent one end of the shaft portion from moving toward the slide rail.

[0011] A second aspect of this application provides a crane including a slide rail, an electric hoist traveling mechanism, and a guide mechanism as described in any of the above embodiments. The guide mechanism is disposed between the electric hoist traveling mechanism and the slide rail to prevent the electric hoist traveling mechanism from moving in a second direction.

[0012] In one embodiment, the electric hoist traveling mechanism includes a first support member, a second support member, a moving member, and a driving member. The first support member and the second support member are arranged opposite to each other. There are two sets of moving members, which are respectively arranged on the first support member and the second support member. The driving member is arranged on the first support member or the second support member and is connected to one of the moving members. The driving member is used to drive the moving member to rotate.

[0013] In one embodiment, the electric hoist traveling mechanism further includes a transmission component, which includes a first gear, a second gear, and a third gear. The moving component includes a first pulley and a second pulley. The first pulley is coaxially arranged with the first gear, and the second pulley is coaxially arranged with the second gear. The output end of the driving component is connected to the third gear, and the two sides of the third gear mesh with the first gear and the second gear, respectively.

[0014] In one embodiment, the electric hoist traveling mechanism further includes a connector connected between the first support member and the second support member, and configured to adjust the distance between the first support member and the second support member when the connector is rotated.

[0015] In one embodiment, the slide rail includes a traveling surface and a guide surface connected to the traveling surface, the traveling surface and the guide surface being perpendicular to each other, the moving member being able to travel relative to the traveling surface in a first direction, and the guide member being able to follow the moving member moving relative to the guide surface in the first direction.

[0016] In the aforementioned guiding mechanism, the rotation of the guide member can be converted into movement along the first direction following the electric hoist traveling mechanism. At the same time, the elastic member provides an elastic force to the guide member in the second direction, so that the guide members on both sides always abut against the slide rail. This keeps the position and distance of the electric hoist traveling mechanism relative to the slide rail fixed, preventing the traveling mechanism from deviating along the second direction on the slide rail and avoiding scraping or detachment between the electric hoist traveling mechanism and the slide rail. This effectively improves the service life and driving stability of the electric hoist traveling mechanism. Attached Figure Description

Detailed Implementation

[0022] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0023] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0027] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0028] refer to Figure 1 As shown, one embodiment of this application provides a crane. This crane is used in industries such as construction, workshops, and transportation, and can perform operations such as lifting, loading, unloading, transferring, and installing goods. The crane includes a slide rail 1, an electric hoist traveling mechanism 2, a guide mechanism, and an electric hoist body (not shown in the figure). The traveling mechanism 2 is disposed on the slide rail 1 and can move along the slide rail 1 in a first direction. The guide mechanism is disposed between the traveling mechanism 2 and the slide rail 1. The guide mechanism can follow the traveling mechanism 2 as it moves relative to the slide rail in the first direction and can prevent the traveling mechanism 2 from deviating in a second direction, thereby guiding the movement of the traveling mechanism 2 in the first direction. The electric hoist body is disposed on the traveling mechanism 2 and is used to perform lifting operations.

[0029] The slide rail 1 includes a web 11, a first wing 12, and a second wing. The first wing 12 and the second wing are respectively perpendicularly disposed on both sides of the web 11. The slide rail 1 is of the I-beam type and extends along a first direction. The side of the first wing 12 closest to the second wing is the traveling surface 121, and the side perpendicularly connected to the traveling surface 121 is the guide surface 122.

[0030] refer to Figure 2 As shown, the walking mechanism 2 includes a first support member 21, a second support member 22, a moving member 23, and a driving member 24. The first support member 21 and the second support member 22 are arranged opposite to each other, and a channel is formed between the first support member 21 and the second support member 22, with the slide rail 1 placed in the channel. Two sets of moving members 23 are provided, with the two sets of moving members 23 respectively disposed on the first support member 21 and the second support member 22. The driving member 24 is disposed on the first support member 21 or the second support member 22 and connected to one of the sets of moving members 23. The driving member 24 is used to drive the moving member 23 to rotate. In the embodiment disclosed in this application, the driving member 24 is disposed on the side of the first support member 21 away from the second support member 22, and the driving member 24 is a motor.

[0031] The moving component 23 includes a first pulley 231 and a second pulley 232. The first pulley 231 and the second pulley 232 are spaced apart along a first direction, and the central axes of the first pulley 231 and the second pulley 232 are parallel to a second direction. The outer circumferential surfaces of the first pulley 231 and the second pulley 232 are disposed on the traveling surface 121. The driving component 24 can drive the first pulley 231 and the second pulley 232 to rotate, and this rotation can drive the entire traveling mechanism 2 to move along the first direction on the traveling surface 121.

[0032] The traveling mechanism 2 also includes a transmission component 25. The transmission component 25 transmits the power of the drive component 24 to the first pulley 231 and the second pulley 232, thereby driving the first pulley 231 and the second pulley 232 to rotate. The transmission component 25 includes a first gear 251, a second gear 252, and a third gear 253. More specifically, a first fixed shaft and a second fixed shaft are provided on one side of the first support component 21. Bearings are provided on both the first and second fixed shafts. The first pulley 231 is sleeved on the first fixed shaft via the bearings, and the first gear 251 is fixedly sleeved on the first pulley 231. The second pulley 232 is sleeved on the second fixed shaft via the bearings, and the second gear 252 is fixedly sleeved on the second pulley 232. The output end of the drive component 24 extends through the first support component 21 into the channel. The third gear 253 is disposed at the output end of the drive component 24 and is located between the first gear 251 and the second gear 252. The two sides of the third gear 253 mesh with the first gear 251 and the second gear 252, respectively.

[0033] When the drive unit 24 is started, the third gear 253 rotates and transmits the driving force of the drive unit 24 to the first gear 251 and the second gear 252, so that the first gear 251 and the second gear 252 rotate. At the same time, the first gear 251 drives the first pulley 231 to rotate, and the second gear 252 drives the second pulley 232 to rotate. The movement of the walking mechanism 2 along the first direction is realized by the rotation of the first pulley 231 and the second pulley 232.

[0034] The traveling mechanism 2 also includes a connecting member 26. The connecting member 26 connects the first support member 21 and the second support member 22. It also adjusts the distance between the first support member 21 and the second support member 22. Rotating the connecting member 26 allows the first support member 21 and the second support member 22 to move away from or closer to each other, accommodating different widths of the slide rail 1 and different sizes of the electric hoist body. After prolonged use of the traveling mechanism 2 or the guiding mechanism, the moving part 23, the transmission part 25, and the guiding mechanism may wear out and require replacement. In this case, screwing on the connecting member 26 allows the first support member 21 and the second support member 22 to move away from each other, thus moving the traveling mechanism 2 and the guiding mechanism away from the slide rail 1. This facilitates component replacement without disassembling the entire traveling mechanism 2 and the guiding mechanism, making maintenance easier.

[0035] In some embodiments, the connector 26 may be a bolt.

[0036] The guiding mechanism includes at least two sets of guiding units 3. In the embodiment disclosed in this application, four sets of guiding units 3 are provided, two sets on each side of the slide rail 1. Two sets of guiding units 3 are spaced apart along the first direction on the first support member 21 and are respectively located on both sides of the moving member 23; the other two sets of guiding units 3 are spaced apart along the first direction on the second support member 22 and are respectively located on both sides of the moving member 23. By placing the guiding units 3 on both sides of the slide rail 1, which extends along the first direction, the guiding units 3 will move relative to the slide rail 1 along the first direction. Thus, the guiding units 3 can guide the walking mechanism 2, ensuring that the walking mechanism 2 always moves along the first direction without any deviation along the second direction. The four sets of guiding units 3 have the same structure and function. One set of guiding units 3 will be described in detail below, while the others will not be described in detail.

[0037] refer to Figure 3 As shown, the guide unit 3 includes a mounting member 31, a guide member 32, and an elastic member 33. The mounting member 31 is used to connect the first support member 21 or the second support member 22; the guide member 32 is disposed on the mounting member 31 and can rotate along the vertical axis, with the second direction, the first direction, and the vertical axis being mutually perpendicular; the elastic member 33 is disposed between the guide member 32 and the mounting member 31, and provides the guide member 32 with an elastic force in the second direction, so that the guide member 32 abuts against the guide surface 122 of the slide rail 1. Specifically, the guide member 32 follows the traveling mechanism and moves relative to the guide surface 122 in the first direction, while rotating along the vertical axis.

[0038] The two sets of guide members 32 in the two sets of guide units 3 always move along the first direction on the guide surface 122. By having the guide members 32 always abut against the guide surface 122, the position and distance between the traveling mechanism 2 and the slide rail 1 are kept fixed, which can prevent the traveling mechanism 2 from deviating along the second direction on the slide rail 1, so that the traveling mechanism 2 always travels along the first direction, thereby avoiding the traveling mechanism 2 from scraping against or separating from the slide rail 1, effectively improving the service life and driving stability of the electric hoist traveling mechanism 2.

[0039] In other embodiments, the guide 32 may also abut against the side of the web 11, and the guide 32 may move along the side of the web 11 in a first aspect and may rotate about a vertical axis.

[0040] Mounting member 31 includes a first side plate 311 and a second side plate 312. The first side plate 311 and the second side plate 312 are arranged opposite each other in the vertical direction and each is provided with a receiving groove 313. An opening 314 is formed between the first side plate 311 and the second side plate 312. Guide member 32 includes a guide portion 321 and a shaft portion 322. The shaft portion 322 passes through the receiving groove 313 and the opening 314. The guide portion 321 is accommodated in the opening 314 and is rotatably mounted on the shaft portion 322. The outer circumferential surface of the guide portion 321 abuts against the guide surface 122. The guide portion 321 can rotate vertically. When the traveling mechanism 2 moves in the first direction, the rotation of the guide portion 321 is converted into movement on the guide surface 122 following the traveling mechanism 2 in the first direction.

[0041] Mounting component 31 also includes mounting part 315. Mounting part 315 is connected between the first support member 21 / second support member 22 and the first side plate 311 and the second side plate 312, and is used to mount the guide mechanism to the traveling mechanism 2.

[0042] The mounting part 315 is provided with welding holes 316 for reinforcing the connection between the guide mechanism and the traveling mechanism 2.

[0043] The mounting section 315 is also provided with mounting holes 317 for installing safety ropes to prevent the crane from falling from a height and injuring people.

[0044] Combination Figure 3 , Figure 4 As shown, the guide mechanism also includes a fixing member 34. There are two fixing members 34: one is disposed at the connection between the first side plate 311 and the mounting part 315, and the other is disposed at the connection between the second side plate 312 and the mounting part 315. The fixing member 34 is used to fix the first side plate 311 and the second side plate 312 to the mounting part 315. Further, the positional relationship, connection relationship and function relationship of the first side plate 311 and the second side plate 312 with other components are basically the same. Taking the first side plate 311 as an example, the fixing member 34 passes through the mounting part 315 and the first side plate 311, and is at least partially accommodated in the receiving groove 313. The portion of the shaft part 322 located in the receiving groove 313 is provided with a through hole 323. The fixing member 34 passes through the through hole 323, so that the shaft part 322 can move in the second direction.

[0045] Furthermore, the fixing member 34 includes a limiting part, a sliding rod part, and a threaded part. The limiting part, the sliding rod part, and the threaded part are connected in sequence. The limiting part is located on the side of the mounting part 315 away from the first side plate 311, the sliding rod part is located in the receiving groove 313, and the shaft part 322 is movable in the second direction. A threaded hole is provided at the end of the receiving groove 313 away from the mounting part 315. After the fixing member 34 passes through the fixing part and the first side plate 311, it is threadedly connected to the threaded hole through the threaded part to fix the fixing member 34.

[0046] The elastic element 33 is sleeved on the fixing element 34. One end of the elastic element 33 abuts against the wall of the receiving groove 313, and the other end abuts against the shaft portion 322. The elastic element 33 releases its elastic force to compress the shaft portion 322. The compression of the shaft portion 322 by the elastic element 33 causes the guide wheel to move along the side close to the guide surface 122, and the outer circumferential surface of the guide wheel always abuts against the guide surface during the movement. When the driving element 24 is activated, the pulley moves on the traveling surface 121. Under the action of the guide wheel always abutting against the guide surface 122, the pulley can always move in the first direction, avoiding the pulley from deviating in the second direction.

[0047] A stop is provided at one end of the shaft portion 322, and the stop is in contact with the side of the first side plate 311 away from the second side plate 312. The guiding mechanism also includes a locking member 35, which can be a nut. The locking member 35 is screwed into the shaft portion 322 and is in contact with the side of the second side plate 312 away from the first side plate 311. The guiding mechanism also includes a limiting member 36. A limiting hole is provided at the end of the shaft portion 322 near the locking member 35, and the limiting member 36 passes through the limiting hole to prevent the locking member 35 from loosening. In addition, during the operation of the crane, the traveling track it uses is formed by connecting several slide rails 1 end to end. At the position where two adjacent slide rails 1 are joined, the locking member 35 and the limiting member 36 can prevent one end of the shaft portion 322 from moving towards the slide rail 1. Specifically, the heights of the first slide rail 1 and the second slide rail 1 are misaligned. When the guide wheel moves to the position where the two slide rails 1 are joined, the locking member 35 and the limiting member 36 can keep the compressive force of the springs in the first side plate 311 and the second side plate 312 stable and synchronized, thereby maintaining the stability of both ends of the shaft 322 and avoiding the problem of the guide wheel being biased due to the single-end force on one end of the shaft 322. This can effectively overcome the problem of the height misalignment at the joint of the slide rails 1 and ensure the stable operation of the guide wheel and the pulley.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
