Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a lifting device and its limiting device. Background Technology

[0002] Overhead cranes, also known as gantry cranes, are characterized by their ability to vertically lift or horizontally move heavy objects suspended from hooks or other lifting devices within a given space. An overhead crane consists of a hoisting mechanism and trolley / trolley traveling mechanisms. Through the coordinated operation of these mechanisms, heavy objects can be lifted and moved within a defined cubic space, and they are commonly found in factory buildings.

[0003] Rail sweepers are commonly used to scan markings on the crane tracks to determine the crane's location. To secure the rail sweepers, they are often connected and welded to the crane body using connectors. However, due to varying factory dimensions, different connectors are required to fix the rail sweepers. These connectors lack universality, and in actual installation, human factors significantly influence the process, making it difficult to find suitable installation points. If the installation point height does not meet design requirements, the rail sweeper may deviate from its intended position, affecting subsequent identification of markings on the track and causing numerous inconveniences for later construction.

[0004] Therefore, how to ensure that the track sweeper is installed in the preset position to identify the markings on the track is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] In the description of this utility model, it should be understood that the terms "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position 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 of this utility model.

[0049] The purpose of this utility model is to provide a lifting device and its limiting device, which can ensure that the rail sweeper 100 is installed in a preset position to identify the markings on the rail 200.

[0050] It should be noted that in this embodiment, the X direction in the attached figure is defined as the first direction, and the Y direction is defined as the second direction. The first direction and the second direction are perpendicular to each other.

[0051] Please see Figures 1 to 7 To achieve the above objectives, this utility model provides a limiting device for installing a rail sweeper 100 onto the body of a lifting equipment to scan and identify markings on the rail 200, including a first mounting plate 300, a mounting assembly 400, a first positioning component, a connecting component 600, and a second positioning component 700.

[0052] The first mounting plate 300 is detachably connected to the lifting equipment body. The lifting equipment body can be provided with a mounting position for mounting the first mounting plate 300, and a first threaded hole is opened in the mounting position. The first mounting plate 300 is provided with a through hole or a second threaded hole corresponding to the first threaded hole. There are at least two through holes or second threaded holes, which are spaced apart. A screw passes through the through hole or the second threaded hole and is screwed into the first threaded hole for mounting and fixing the first mounting plate 300.

[0053] The mounting component 400 is connected to the first mounting plate 300 and can move relative to the first mounting plate 300 along a first direction, preferably a vertical direction. By moving the mounting component 400 along the first direction, the height of the mounting component 400 can be adjusted.

[0054] The first positioning element is connected to the mounting assembly 400 so that the moved mounting assembly 400 is fixed relative to the first mounting plate 300. When the mounting assembly 400 needs to be adjusted, the first positioning element is removed or loosened, and the mounting assembly 400 is moved manually or with the help of external force. Then the first positioning element is installed or tightened to ensure that the position of the adjusted mounting assembly 400 is relatively fixed.

[0055] The connector 600 is connected to the track sweeper 100 and the mounting assembly 400, and the connector 600 can move relative to the mounting assembly 400 in a second direction, preferably a horizontal direction, and can move closer to or further away from the track 200 when moving in the second direction. By moving the connector 600 in the second direction, the track sweeper 100 can be moved accordingly to change the distance between the track sweeper 100 and the track 200.

[0056] The second positioning member 700 is used to fix the connector 600 to the mounting assembly 400 to ensure that the connector 600, after being positioned, can be fixed relative to the mounting assembly 400, thereby fixing the rail sweeper 100 relative to the mounting assembly 400.

[0057] The first mounting plate 300 is detachably connected to the lifting equipment body. The position of the mounting component 400 connected to the first mounting plate 300 is adjusted in the first direction, and the position of the connector 600 connected to the mounting component 400 is adjusted in the second direction. Then, the first positioning component and the second positioning component 700 are fixed so that the rail sweeper 100 connected to the connector 600 can move to a preset height and maintain a preset distance from the rail 200. This setting can ensure that the rail sweeper 100 is installed in a preset position to identify the markings on the rail 200.

[0058] It should be noted that there is no specific order between adjusting the position of the mounting component 400 relative to the first mounting plate 300 in the first direction and adjusting the position of the connector 600 relative to the mounting component 400 in the second direction. Adjustments in both directions can be made according to actual needs.

[0059] In this embodiment, the first mounting plate 300 is provided with a first oblong hole 310, and the first oblong hole 310 extends along a first direction and is relatively long. The mounting assembly 400 includes a second mounting plate 410 and a third mounting plate 420. The second mounting plate 410 includes a first plate body 411 and a second plate body 412 that are connected and angled together. The first plate body 411 is movably connected to the first oblong hole 310. The third mounting plate 420 is connected to the second plate body 412, and the bottom of the third mounting plate 420 is provided with a first mounting hole 421 for connecting the connector 600.

[0060] It is understandable that the length of the first oblong hole 310 in the first direction can determine the maximum distance that the second mounting plate 410 can move relative to the first mounting plate 300. By making the first oblong hole 310 longer, the adjustment range of the second mounting plate 410 in the first direction is increased. By setting the first plate 411 and the second plate 412 at an angle, the third mounting plate 420 connected to the second plate 412 and the first mounting plate 300 connected to the first plate 411 are set at an angle, so as to provide more space for the subsequent connection of the connector 600 and the third mounting plate 420.

[0061] The third mounting plate 420 has a second oblong hole 422 at its top, and the second oblong hole 422 extends along the first direction; the first plate 411 has a first fixing hole 4111, and the second plate 412 has a second fixing hole 4121; the first positioning member includes a first connecting member passing through the first fixing hole 4111 and the first oblong hole 310, and a second connecting member 510 passing through the second fixing hole 4121 and the second oblong hole 422, so that the first mounting plate 300, the second mounting plate 410 and the third mounting plate 420 can move relative to each other along the first direction.

[0062] It is understandable that the first oblong hole 310 enables the second mounting plate 410 to have a large adjustment range in the first direction. The top of the third mounting plate 420 is provided with a second oblong hole 422, and the second oblong hole 422 extends along the first direction, enabling the third mounting plate 420 to move relative to the second mounting plate 410 in the first direction. The first mounting plate 300, the second mounting plate 410 and the third mounting plate 420 can move relative to each other in the first direction, and the sum of the displacements of the second mounting plate 410 and the third mounting plate 420 is the displacement of the connector 600 connected to the third mounting plate 420.

[0063] The first fixing hole 4111 and the second fixing hole 4121 are provided to facilitate the relative movement of the first mounting plate 300, the second mounting plate 410 and the third mounting plate 420, and their fixation by the first connector and the second connector 510. When the first connector and the second connector 510 are bolts, the corresponding nuts only need to be loosened to allow the bolts to slide inside the first waist-shaped hole 310 and the second waist-shaped hole 422, so that the position adjustment process does not require disassembly and improves the efficiency of adjusting the position of the connector 600.

[0064] There are two second waist-shaped holes 422, and the two second waist-shaped holes 422 are spaced apart in the first direction. The second connector 510 and the second waist-shaped holes 422 correspond one to one to restrict the relative rotation of the second plate 412 and the third mounting plate 420, and at the same time improve the stability of the connection between the second mounting plate 410 and the third mounting plate 420.

[0065] The length of a single second oblong hole 422 in the first direction is 0.2 to 0.4 times the length of the first oblong hole 310 in the first direction. When the height of the connector 600 needs to be adjusted within a large range, it can be fixed by moving the first connector relative to the first oblong hole 310. When the height of the connector 600 only needs to be adjusted within a small range, it can be fixed by moving the second connector 510 relative to the second oblong hole 422, thereby further improving the efficiency of adjusting the height of the connector 600.

[0066] In this embodiment, the connector 600 includes a third plate 610 and a fourth plate 620 that are connected and angled together. The third plate 610 is used to fix the rail sweeper 100. The fourth plate 620 is connected to the end of the third plate 610 that is away from the rail sweeper 100. A fixing member 630 is provided on the side of the fourth plate 620 that is away from the third plate 610. The fixing member 630 extends along the second direction and can pass through the first mounting hole 421.

[0067] In some embodiments, the fixing member 630 is specifically a screw; the second positioning member 700 includes a first nut 710 and a second nut 720 sleeved on the fixing member 630. The first nut 710 and the second nut 720 can respectively abut against the two sides of the third mounting plate 420 in the first direction to adjust the distance between the rail sweeper 100 and the third mounting plate 420. When it is necessary to adjust the horizontal position of the rail sweeper 100, first loosen the first nut 710 and the second nut 720, then move the fixing member 630 and tighten it again with the first nut 710 and the second nut 720. By using the distance between the third mounting plate 420 and the center line A of the track 200 in the second direction as a fixed value, the distance between the center line of the rail sweeper 100 and the center line of the track 200 can be obtained.

[0068] Furthermore, considering that the track sweeper 100 is fixedly connected to the third plate 610, and that the third plate 610 and the fourth plate 620 are an integral structure, the distance between the track sweeper 100 and the center line of the track 200 can be obtained by subtracting the distance L between the fourth plate 620 and the center line A of the track 200 in the second direction.

[0069] Preferably, the first plate 411 and the third plate 610 are parallel to each other, the second plate 412 and the fourth plate 620 are parallel to each other, a first reinforcing rib is provided between the first plate 411 and the second plate 412, and a second reinforcing rib is provided between the third plate 610 and the fourth plate 620.

[0070] The first plate 411 and the second plate 412 are perpendicular to each other, and the third plate 610 and the fourth plate 620 are perpendicular to each other. A first reinforcing rib is provided between the first plate 411 and the second plate 412, and a second reinforcing rib is provided between the third plate 610 and the fourth plate 620 to enhance the structural strength of the second mounting plate 410 and the connector 600. Thickening treatment can also be carried out at the connection between the first plate 411 and the second plate 412, and at the connection between the third plate 610 and the fourth plate 620, which can also achieve the effect of strengthening the structural strength.

[0071] In addition, a lifting device is also included, which includes the aforementioned limiting device and has the same beneficial effects as the aforementioned limiting device, which will not be described in detail here.

[0072] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0073] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0074] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
