Description

Technical Field

[0001] This application relates to the field of hoisting equipment technology, and more specifically, to obstacle-crossing hoisting devices. Background Technology

[0002] Global trends such as energy transition, resource demand, and infrastructure upgrades have created a rigid demand for large-scale, high-efficiency, and extreme-condition operations. Heavy equipment, as a crucial pillar of the industrial sector, is an essential prerequisite for industrialized and intelligent production lines to overcome technological barriers and achieve economies of scale and industrial upgrading. Therefore, in an increasing number of key industrial sectors, such as lithium batteries, photovoltaics, wind power, aerospace, shipbuilding, and petrochemicals, the application of heavy equipment is an inevitable choice for their development.

[0003] Due to their large size and weight, heavy equipment is very expensive, with unit prices often reaching millions, tens of millions, or even hundreds of millions of RMB. In addition, the energy consumption, maintenance, spare parts, and labor costs during the operation of heavy equipment are also enormous. Over the entire life cycle, the accumulated operating and maintenance costs are likely to exceed the initial purchase cost. Therefore, heavy equipment has indisputably become the core asset of manufacturing enterprises.

[0004] After heavy equipment is put into use, its maintenance and repair are absolute prerequisites for preventing catastrophic accidents and ensuring the safety of personnel and assets. Maximizing equipment uptime ensures production continuity and the company's core revenue streams, and is also key to extending equipment life, optimizing total life cycle costs, and maintaining the company's long-term competitiveness.

[0005] The maintenance and repair of heavy equipment often inevitably requires its handling. Due to its large size and heavy weight, the handling of heavy equipment has always presented many technical challenges. For example, traditional handling equipment cannot adapt to the complex obstacle environment of the factory (embankments, steps, ditches, etc.). Utility Model Content

[0006] The purpose of this application is to provide an obstacle-crossing hoisting device that can overcome obstacles and improve environmental adaptability.

[0007] To achieve the above objectives, this utility model provides an obstacle-crossing hoisting device, comprising: A load-bearing beam, on which a hoisting assembly is provided; At least four telescopic support columns, each having a support end and a movable end at its two ends, the support end of which is connected to the load-bearing beam, and the at least four telescopic support columns are distributed at intervals along the length of the load-bearing beam. A movable component is provided at the mobile end, and the telescopic support column and the load-bearing beam move through the movable component, thereby driving the hoisting component to move; When one of the telescopic support columns needs to overcome an obstacle, the other telescopic support columns rise to increase the height of the telescopic support column that needs to overcome the obstacle, so that the height of the moving component on the telescopic support column that needs to overcome the obstacle exceeds the obstacle. Then, the moving component moves to drive the telescopic support column that needs to overcome the obstacle to overcome the obstacle.

[0008] In an optional embodiment, the telescopic support column includes a first support member and a second support member, the first support member and the second support member being slidably telescopically coupled, the support end being disposed on the first support member at one end away from the second support member, and the movable end being disposed on the second support member at one end away from the first support member.

[0009] In an optional embodiment, the first support member and the second support member are respectively provided with locking through holes for mounting pins.

[0010] In an optional embodiment, the second support member is sleeved outside the first support member, and the first support member and the second support member slide and extend in cooperation.

[0011] In an optional embodiment, the second support member is provided with a pry seat, the pry seat is provided with a hinge plate and a pry arm, one end of the hinge plate is hinged to the pry seat, and the other end is hinged to the pry arm. The pry arm is used to pry the first support member out of the second support member, thereby extending the telescopic support column.

[0012] In an optional embodiment, the support end of the telescopic support column is provided with a mounting shell, which is fitted onto the load-bearing beam.

[0013] In an optional embodiment, a lateral support column is also included, which is used to support the side of the load-bearing beam. One end of the lateral support column is hinged to the mounting shell, and the other end is supported on the ground by a balance wheel. A fixing bolt for locking the tilt angle of the lateral support column is provided between the lateral support column and the mounting shell.

[0014] In an alternative embodiment, the mounting housing can slide and lock on the load-bearing beam.

[0015] In an optional embodiment, the moving component includes a rolling seat and a roller, the rolling seat being rotatably connected to the moving end, and after the rolling seat rotates relative to the moving end to the desired angle, the moving end and the rolling seat are locked by a flange. The rolling seat is provided with at least two rollers.

[0016] In an optional embodiment, a first elastic element is provided between the rolling seat and the moving end.

[0017] In an optional embodiment, the roller is equipped with a braking element.

[0018] In an optional embodiment, a connecting component is further included, wherein the connecting component is disposed between two adjacent movable components, one end of the connecting component is hinged to the rolling seat of one of the movable components, and the other end of the connecting component is hinged to the rolling seat of another adjacent movable component.

[0019] In an optional embodiment, one end of the load-bearing beam is provided with a first extension component and the other end is provided with a second extension component. When the number of load-bearing beams is at least two, the first extension component of one load-bearing beam cooperates with the second extension component of another adjacent load-bearing beam to connect the two adjacent load-bearing beams.

[0020] The obstacle-crossing lifting device provided in this application is equipped with at least four telescopic support columns. When one of the telescopic support columns encounters an obstacle protruding from the ground, the remaining telescopic support columns rise, increasing the height of the telescopic support column that needs to cross the obstacle. This raises the height of the moving component on the telescopic support column above the obstacle, and then the moving component moves to drive the obstacle-crossing lifting device over the obstacle. By sequentially controlling the extension, movement, and retraction of different telescopic support columns, the four telescopic support columns can successively cross obstacles protruding from the ground, effectively overcoming the problem that traditional handling equipment cannot adapt to complex obstacle environments in factories.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

They are used only for the convenience of describing this application and for 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. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] Embodiments of this application provide an obstacle-crossing hoisting device, including a load-bearing beam 100, a telescopic support column 200, and a moving component 300.

[0029] A lifting assembly 700 is provided on the load-bearing beam 100. The lifting assembly 700 is used for lifting equipment or other entities. For example, the lifting assembly 700 is configured as an electric hoist or a manual hoist, etc.

[0030] The number of telescopic support columns 200 should be at least four.

[0031] For example, the telescopic support column 200 is set vertically or slightly inclined in the vertical direction, with the slight inclination angle being, for example, 1°-5°.

[0032] The telescopic support column 200 has a support end 230 and a moving end 240 at its two ends. The support end 230 of the telescopic support column 200 is connected to the load-bearing beam 100, and at least four telescopic support columns 200 are distributed sequentially at intervals along the length of the load-bearing beam 100. The telescopic support columns 200 can be set at equal intervals or at unequal intervals.

[0033] For example, in this embodiment, four telescopic support columns 200 are provided. In other embodiments, five telescopic support columns 200 are provided. Of course, in other embodiments, other numbers of telescopic support columns 200 may be provided, such as six, seven, or eight.

[0034] For example, the telescopic support column 200 includes, but is not limited to, a hydraulic telescopic mechanism, a pneumatic telescopic mechanism, an electric actuator telescopic mechanism, a threaded screw telescopic mechanism, or a linear motor.

[0035] The mobile terminal 240 is equipped with a moving component 300. The telescopic support column 200 and the load-bearing beam 100 move through the moving component 300, thereby driving the hoisting component 700 to move.

[0036] When one of the telescopic support columns 200 needs to overcome an obstacle, the other telescopic support columns 200 rise to increase the height of the telescopic support column 200 that needs to overcome the obstacle, so that the height of the moving component 300 on the telescopic support column 200 that needs to overcome the obstacle exceeds the obstacle. Then, the moving component 300 moves to drive the telescopic support column 200 that needs to overcome the obstacle to overcome the obstacle.

[0037] Assuming four telescopic support columns 200 are installed, and these four telescopic support columns 200 are sequentially designated as the first column, second column, third column, and fourth column along the length of the load-bearing beam 100, and assuming the obstacle-crossing hoisting device needs to move along a first direction (the direction from the fourth column to the first column), when the first column encounters an obstacle protruding from the ground, the operator controls the extension of the second, third, and fourth columns, thereby raising the first column, the load-bearing beam 100, the hoisting assembly 700, and the equipment hoisted by the hoisting assembly 700. When the height of the moving component 300 on the first column exceeds the height of the obstacle, the obstacle-crossing hoisting device moves along the first direction via the moving components 300 on the second, third, and fourth columns, allowing the first column and its moving component 300 to cross the obstacle. The operator then controls the retraction of the second, third, and fourth columns, and the height of the first column... As the height decreases, the movable component 300 on the first support column contacts the ground. At this point, the second, third, and fourth support columns need to cross the obstacle in sequence. When controlling the second support column to cross the obstacle, the operator controls the first, third, and fourth support columns to extend, raising the second support column, the load-bearing beam 100, the hoisting component 700, and the equipment hoisted by the hoisting component 700. When the height of the movable component 300 on the second support column exceeds the obstacle, the obstacle-crossing hoisting device moves along the first direction through the movable components 300 on the first, third, and fourth support columns, so that the second support column and the movable component 300 on the second support column cross the obstacle. The operator controls the first, third, and fourth support columns to shorten, lowering the height of the second support column, and the movable component 300 on the second support column contacts the ground, thus completing the obstacle crossing of the second support column. By repeating the above-described process, the obstacle crossing of the third and fourth support columns can also be completed.

[0038] If the obstacle encountered is a trench, there is no need to extend the four telescopic support columns 200. The four telescopic support columns 200 can be moved directly by the moving component 300 to pass over the trench in sequence.

[0039] During the above operation, the width of obstacles protruding from the ground and trench-like obstacles along the first direction is less than the minimum distance between two adjacent telescopic support columns 200. If the width of the obstacle along the first direction is greater than the distance between two adjacent telescopic support columns 200, the following embodiments will provide solutions such as extending the length of the load-bearing beam 100 and adjusting the distance between two adjacent telescopic support columns 200, so that the minimum distance between two adjacent telescopic support columns 200 is greater than the width of the obstacle.

[0040] like Figure 1As shown, in one embodiment, the telescopic support column 200 includes a first support member 210 and a second support member 220. The first support member 210 and the second support member 220 are slidably telescopically coupled. The support end 230 is disposed on the first support member 210 at one end away from the second support member 220, and the movable end 240 is disposed on the second support member 220 at one end away from the first support member 210.

[0041] The sliding and telescopic movement of the first support member 210 relative to the second support member 220 can be controlled by a telescopic component, which includes, but is not limited to, a hydraulic telescopic mechanism, a pneumatic telescopic mechanism, an electric push rod telescopic mechanism, a threaded screw telescopic mechanism, or a linear motor.

[0042] like Figure 1 As shown, in one embodiment, the first support member 210 and the second support member 220 are respectively provided with locking through holes 250 for mounting pins.

[0043] A pin is installed in the locking through hole 250 on the first support member 210 and the second support member 220 to lock the first support member 210 and the second support member 220. This keeps the length of the telescopic support column 200 stable during hoisting and improves reliability. When the telescopic support needs to be extended or shortened, the pin can be removed from the locking through hole 250 to unlock the first support member 210 and the second support member 220.

[0044] For example, the first support member 210 has multiple locking through holes 250, and the multiple locking through holes 250 are sequentially distributed along the length direction of the first support member 210; the second support member 220 has multiple locking through holes 250, and the multiple locking through holes 250 are sequentially distributed along the length direction of the second support member 220. The multiple locking through holes 250 on the first support member 210 and the second support member 220 allow the first support member 210 and the second support member 220 to be extended and retracted to different positions and then locked.

[0045] like Figure 1 As shown, in one embodiment, the second support member 220 is sleeved outside the first support member 210, and the first support member 210 and the second support member 220 slide and extend in cooperation.

[0046] The second support member 220 is provided with a pry seat 260, and the pry seat 260 is provided with a hinge plate 280 and a pry arm 270. One end of the hinge plate 280 is hinged to the pry seat 260, and the other end is hinged to the pry arm 270. The pry arm 270 is used to pry the first support member 210 out of the second support member 220, thereby extending the telescopic support column 200.

[0047] During use, if the telescopic support column 200 needs to be extended, first install the hinge plate 280 onto the pry seat 260, then install the pry arm 270 onto the hinge plate 280. Install a pin on the first support member 210 near the locking through hole 250 of the pry arm 270, and then install the pry arm 270 onto the pin. Remove the locking pins on the first support member 210 and the second support member 220, thus unlocking the first support member 210 and the second support member 220. After the operator pries the first support member 210 to extend the second support member 220 using the pry arm 270, the telescopic support column 200 will extend to the required length. Then, install the pin into the locking through hole 250 of the first support member 210 and the second support member 220 to lock the first support member 210 and the second support member 220.

[0048] If it is necessary to shorten the telescopic support column 200, first assemble the hinge plate 280 and the pry arm 270 onto the pry seat 260; install a pin on the first support member 210 near the locking through hole 250 of the pry arm 270, and install the pry arm 270 onto the pin. Remove the locking pins on the first support member 210 and the second support member 220, and the first support member 210 and the second support member 220 are unlocked; the operator uses the pry arm 270 to pry the first support member 210, causing the first support member 210 to slowly sink into the second support member 220. After the telescopic support column 200 is shortened to the required length, install the pin into the locking through hole 250 of the first support member 210 and the second support member 220 to lock the first support member 210 and the second support member 220.

[0049] like Figure 1 As shown, in one embodiment, the support end 230 of the telescopic support column 200 is provided with a mounting shell 110, which is sleeved on the load-bearing beam 100. Exemplarily, the mounting shell 110 and the load-bearing beam 100 are detachably connected by bolts. The support end 230 is provided with a square connecting column and a locking bolt for connecting the load-bearing beam 100. One end of the square connecting column is provided on the support end 230, and the other end is connected to the locking bolt. The load-bearing beam 100 is provided with a square mating hole. The square connecting column and the locking bolt are installed into the square mating hole of the load-bearing beam 100, and a nut is installed on the locking bolt, thereby fixing the telescopic support column 200 to the load-bearing beam 100. The square connecting column prevents the telescopic support column 200 from rotating around the circumference of the locking bolt.

[0050] However, in another embodiment, the mounting shell 110 is slidably engaged with the load-bearing beam 100 so that the position of the telescopic support column 200 on the load-bearing beam 100 is adjustable, thereby adjusting the distance between adjacent telescopic support columns 200 and improving the obstacle-crossing capability of the obstacle-crossing hoisting device.

[0051] like Figure 1As shown, in one embodiment, the obstacle-crossing hoisting device further includes a lateral support column 600, which is used to support the side of the load-bearing beam 100. One end of the lateral support column 600 is hinged to the mounting shell 110, and the other end is supported on the ground by a balance wheel. A fixing bolt 620 for locking the tilt angle of the lateral support column 600 is provided between the lateral support column 600 and the mounting shell 110.

[0052] like Figure 4 As shown, exemplarily, a hinge seat 610 is provided on the mounting housing 110, and a lateral support column 600 is hinged to the mounting housing 110 by a pin. The lateral support column 600 is configured as a telescopic structure and its length is locked by bolts.

[0053] For example, the hinge seat 610 is provided with a locking pin hole, and a fixing bolt 620 is provided at the locking pin hole of the hinge seat 610. After the angle of the lateral support column 600 is adjusted, its angle is locked by the fixing bolt 620.

[0054] The hinged seat 610 allows the lateral support column 600 to adjust the angle of the tilt support, thereby further ensuring the stability and reliability of the obstacle-crossing hoisting device during operation, while flexibly adapting to different handling scenarios and handling needs.

[0055] like Figure 1 As shown, in one embodiment, the moving component 300 includes a rolling seat 310 and a roller 320, with the rolling seat 310 rotatably connected to the moving end 240.

[0056] After the rolling seat 310 rotates relative to the moving end 240 to the required angle, the moving end 240 and the rolling seat 310 are locked by the flange.

[0057] For example, such as Figure 1 and Figure 3 As shown, a first flange 340 is provided on the movable end 240, and a second flange 350 is provided on the fixed seat. A rotating shaft for rotatably connecting the movable end 240 is provided on the second flange 350. The rotating shaft is rotatably engaged with the movable end 240. The first flange 340 and the second flange 350 are detachably connected by bolts.

[0058] The rolling seat 310 is provided with at least two rollers 320. Exemplarily, the rolling seat 310 is provided with two rollers 320; in another embodiment, the rolling seat 310 is provided with four rollers 320. In other embodiments, the number of rollers 320 may also be other than five, six, or ten.

[0059] For example, the roller 320 is configured as a single wheel; in another embodiment, the roller 320 is configured as an obstacle-crossing wheel, which has three wheels arranged in a triangular pattern.

[0060] In one embodiment, for example, a brake is provided on the roller 320, which is used to lock the roller 320 in the rotation direction so as to stop the roller 320.

[0061] like Figure 1 As shown, in one embodiment, a first elastic element 330 is provided between the rolling seat 310 and the moving end 240. The first elastic element 330 is used to buffer vibration and improve the stability of the obstacle-crossing hoisting device.

[0062] For example, elastic elements include, but are not limited to, helical springs, wave springs, disc springs, leaf springs, steel leaf springs, rubber springs, air springs, etc.

[0063] like Figure 1 As shown, in one embodiment, the obstacle-crossing hoisting device further includes a connecting component 400, which is provided between two adjacent moving components 300. One end of the connecting component 400 is hinged to the rolling seat 310 of one moving component 300, and the other end of the connecting component 400 is hinged to the rolling seat 310 of another adjacent moving component 300.

[0064] For example, the connecting assembly 400 includes a plate, a first hinge shaft and a second hinge shaft. The first hinge shaft is fixedly disposed at one end of the plate, and the second hinge shaft is fixedly disposed at the other end of the plate. The first hinge shaft of the connecting assembly 400 is hinged to the rolling seat 310 of one of the moving assemblies 300, and the second hinge shaft of the connecting assembly 400 is hinged to the rolling seat 310 of the adjacent moving assembly 300.

[0065] For example, the first hinge shaft and the second hinge shaft are fixedly mounted on the plate by means of welding, snap-fitting, bolting, or integral molding.

[0066] In this application, the upper ends of two adjacent telescopic support columns 200 are connected by a load-bearing beam 100 and a mounting shell 110 to reduce the swaying of the upper ends of the telescopic support columns 200. The lower ends of two adjacent telescopic support columns 200 are connected by a rolling seat 310 and a connecting assembly 400 to reduce the swaying of the lower ends of the telescopic support columns 200, thereby improving the stability of the obstacle-crossing hoisting device of this application. Furthermore, during hoisting, the plate of the connecting assembly 400 can also hold tools and other items, improving convenience.

[0067] like Figure 1 and Figure 2As shown, in one embodiment, a first extension component 500 is provided at one end of the load-bearing beam 100 and a second extension component 510 is provided at the other end. When the number of load-bearing beams 100 is at least two, the first extension component 500 of one load-bearing beam 100 cooperates with the second extension component 510 of another adjacent load-bearing beam 100 to connect the two adjacent load-bearing beams 100.

[0068] For example, such as Figure 1 As shown, the first expansion component 500 is configured as a square mounting hole, and the second expansion component 510 is configured as a square column. Bolt holes are provided on the load-bearing beam 100 near the square mounting hole, and bolts are installed into these bolt holes to lock the square column within the square mounting hole. In another embodiment, the second expansion component 510 is configured as a square mounting hole, the first expansion component 500 is configured as a square column, and bolt holes are provided on the load-bearing beam 100 near the square mounting hole. Bolts are installed into these bolt holes to lock the square column within the square mounting hole.

[0069] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
