Lifting device and tipping apparatus

Abstract

The application discloses a lifting device and a tipping device, and the lifting device comprises a beam frame, a lifting frame, a lifting mechanism and a side moving mechanism. Since the side moving mechanism and the moving support are directly arranged in the mounting frame, the internal space of the lifting frame is maximally utilized, and the thickness of the whole lifting frame is reduced. Since the winch assembly is arranged in the beam frame, when the lifting device is subjected to the impact of the scattered materials coming from the bottom direction of the lifting device in the turning and unloading working condition, the protection effect of the structure is very obvious, and the scattered materials are prevented from entering the above components and causing damage.

Description

Technical Field

[0001] This application relates to the field of railway transport tippler technology, and in particular to a tippler device with a lifting mechanism. Background Technology

[0002] A tippler unloading system is a large-scale automated unloading system used in power plants, ports, metallurgy, coal, and coking plants. It is a device that unloads bulk materials loaded in open railway wagons. The tippler is used to clamp and pull in heavy wagons before tipping them over for unloading. It is a crucial piece of equipment for transferring materials to material yards or combustion zones, and is an important single unit component of the tippler unloading system. Currently, common centralized bulk material handling methods are as follows:

[0003] 1. Transportation is carried out by open wagons. The wagon's cargo box and single-section frame platform are integrated as a whole, allowing bulk materials to be directly loaded into the open cargo box from top to bottom.

[0004] 2. Container transport involves securing containers filled with bulk materials to a single carriage platform of a train, which then moves the containers for transport.

[0005] 3. Transport by combination of container and open wagon, that is, the container is hoisted into the open wagon compartment for transfer.

[0006] The containers mentioned above can be lifted by a hoisting mechanism. Conventional spreader side-shifting mechanisms and devices are located outside the spreader's own structure, occupying a large amount of height space. Furthermore, components such as the side-shifting cylinders are exposed on the outside, making them unsuitable for use in environments with direct impact from loose materials. Utility Model Content

[0007] This application proposes a lifting device and tipping equipment that can reduce the overall height of the lifting equipment and the lateral shifting system. It has a compact structure, occupies little space, and has a significant impact protection effect on bulk materials.

[0008] This application discloses a lifting device, comprising:

[0009] Beam frame;

[0010] Hangers, including mounting frames;

[0011] The lifting mechanism includes a winch assembly disposed within the beam frame and a movable support slidably disposed within the mounting frame; the winch assembly is driven to the movable support and is used to drive the movable support to move up and down along a first direction;

[0012] The lateral shifting mechanism includes a lateral shifting drive member disposed on the mounting frame. The lateral shifting drive member is connected to the movable bracket and the mounting frame respectively, and is used to drive the mounting frame and the movable bracket to slide relative to each other along a second direction.

[0013] In some embodiments, the beam frame has a first chamber for accommodating the hoisting assembly; the mounting frame has a second chamber for accommodating the movable support and the lateral movement mechanism; and the hanger is capable of docking with the beam frame to connect the first chamber and the second chamber.

[0014] In some embodiments, the beam frame has a receiving groove on the side facing the hanger for accommodating the hanger, and the lifting device further includes a locking component for locking the hanger in the receiving groove.

[0015] In some embodiments, the locking component includes:

[0016] A locking element is rotatably mounted on the beam frame, and one end is used to dock with the hanger;

[0017] A locking drive is driven to the locking member, and the locking drive is used to drive the locking member to rotate and dock with the hanger.

[0018] In some embodiments, the mounting frame has two movable supports arranged side by side; the hoisting device further includes movable pulleys rotatably mounted on the movable supports, the movable pulleys being respectively arranged near the four corners of the mounting frame, and the winch mechanism including ropes wound around the movable pulleys.

[0019] In some embodiments, the lifting device further includes a frame for mounting the beam, the beam being slidably connected to the frame, and the lifting device further includes a spacing adjustment mechanism for adjusting the spacing between two adjacent beams.

[0020] In some embodiments, the lifting mechanism further includes a drive shaft connecting two adjacent beams, and each of the hoisting mechanisms is connected to the drive shaft and shares a common drive source.

[0021] This application also proposes a tipping device, including the aforementioned lifting device.

[0022] The hoisting device in this application includes a beam frame, a hanger, a lifting mechanism, and a lateral shifting mechanism. Since the lateral shifting mechanism and the moving support are directly arranged inside the installation frame, the internal space of the hanger is utilized to the maximum extent, reducing the overall thickness of the hanger. Since the hoisting assembly is arranged inside the beam frame, the structure has a significant protective effect when facing the impact of loose material coming from the bottom of the hoist during the overturning and unloading operation, preventing loose material from entering the above-mentioned components and causing damage.

[0027] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] The solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments in this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0030] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0031] In this application, all directional indicators such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationships and movement of the components in a specific posture as shown in the attached figures. If the specific posture changes, the directional indicators will also change accordingly.

[0032] This application discloses a lifting device, referring to... Figures 1 to 4The hoisting device includes: a beam frame 10; a hanger 20, including a mounting frame 21; a lifting mechanism, including a winch assembly 40 disposed in the beam frame 10 and a movable support 23 slidably disposed in the mounting frame 21; the winch assembly 40 is used to drive the movable support 441 to move up and down along a first direction; and a lateral movement mechanism 30, including a lateral movement drive member 31 disposed in the mounting frame 21, the lateral movement drive member 31 being connected to the movable support 23 and the mounting frame 411 respectively, and used to drive the mounting frame 21 and the movable support 23 to slide relative to each other along a second direction.

[0033] In this embodiment, since the lateral shifting mechanism 30 and the moving bracket 23 are directly arranged inside the mounting frame 21, the internal space of the hanger is utilized to the maximum extent, reducing the thickness of the entire hanger. Since the hoisting assembly 40 is arranged inside the beam frame 10, the protective effect of this structure is very obvious when facing the impact of loose material coming from the bottom of the hanger during the overturning and unloading operation, preventing loose material from entering the above-mentioned components and causing damage.

[0034] In some embodiments, refer to Figures 1 to 4 The beam frame 10 has a first chamber 111 for accommodating the hoisting assembly 40; the mounting frame 21 has a second chamber 211 for accommodating the movable support and the lateral shifting mechanism 30. The hanger 20 can dock with the beam frame 10, so that the first chamber 111 and the second chamber 211 are connected. In this embodiment, the beam frame 10 is provided with a shell 11, and the shell 11 has a first chamber 111 inside. The shell 11 has a first clearance hole that communicates with the first chamber 111; the mounting frame 21 has a second clearance hole that communicates with the second chamber 211; the first clearance hole and the second clearance hole are used for ropes to pass through. The hanger 20 can dock with the beam frame 10, so that the first clearance hole and the second clearance hole are connected. The first chamber 111 and the second chamber 211 form a connected chamber. When the lifting device lifts the container, the lifting frame 20 is connected to the shell 11, and the two form a complete cavity inside each other. The entire lifting mechanism is housed in this cavity and isolated from the outside. During unloading, loose material will not enter the lifting mechanism to avoid damage.

[0035] It is worth noting that the aforementioned locking component can be located in the housing 11, and the lateral displacement component can also be located in the second chamber 211 to prevent loose material from entering and causing contamination and motion interference. The aforementioned motion interference can lead to jamming and mechanical damage to the moving parts. Specifically, it prevents loose material from entering the gap between the push rod and the cylinder of the lateral displacement drive 31, and prevents loose material from sticking to the pulleys and ropes, or getting stuck between the pulleys and ropes, thus avoiding mechanical damage, chemical corrosion, and structural damage.

[0036] In some embodiments, refer to Figures 1 to 4The beam frame also has a receiving groove 12 on the side facing the receiving platform, which is used to connect with the hanger 20. In this embodiment, the hanger 20 can be accommodated in the receiving groove 12 and is limited by the receiving groove 12, so the hanger 20 will not swing in the receiving groove 12. The hanger 20 can be configured as a rectangular frame structure, and a rectangular notch can be selected for the receiving groove 12. When the container is overturned, the hanger 20 is also limited by the receiving groove 12, and will not overturn.

[0037] Furthermore, the hoisting mechanism also includes a locking assembly, which includes: a locking member 51, rotatably mounted on the beam frame, with one end for docking with the hanger 20; and a locking drive member 52, remotely connected to the locking member 51, which drives the locking member 51 to rotate and dock with the hanger 20. In this embodiment, the locking member 51 can be located in the area of ​​the beam frame 10 near the aforementioned receiving groove 12. When the locking member 51 rotates, one end can pass through the beam frame and enter the aforementioned receiving groove 12 to dock with the hanger 20 and lock the hanger 20. The locking drive member 52 can optionally be a hydraulic cylinder located in the beam frame 10, with one end of the hydraulic cylinder hinged to the beam frame 10 and the other end hinged to the end of the locking member 51 away from the hanger 20. It is worth noting that when locking the hanger 20, the locking member 51 can clamp the hanger 20 together with the inner top surface of the receiving groove 12. The hydraulic cylinder drives the locking component 51 to swing, and can also swing the locking component 51 back into the beam frame 10 to unlock it. The locking component allows the hanger 20 to be completely fixed in the receiving groove 12 without the need for continuous operation of the lifting component. In addition, in this embodiment, a pair of locking components can be provided, specifically, they can be respectively set on both sides of the receiving groove 12, making the locking state more stable, and the frame will be locked in both forward and reverse rotation.

[0038] In some embodiments, refer to Figures 1 to 4 Two movable supports 23 are arranged side-by-side along a third direction on the mounting frame 21. The lifting device also includes movable pulleys 41 rotatably mounted on the movable supports 441. The movable pulleys 41 are respectively located near the four corners of the mounting frame 21 to ensure that the lifting frame 20 is subjected to balanced force and remains basically horizontal when lifting the container. In this embodiment, the winch mechanism is connected to the movable supports 23 via a rope. One end of the rope is fixed to the winch mechanism, and the other end passes through and wraps around the movable pulley before being fixedly connected to the movable support 23. The winch mechanism can lift the lifting frame by winding the rope.

[0039] In some embodiments, refer to Figures 1 to 4The lifting device also includes a frame for mounting the beam frame 10, with the beam frame 10 slidably connected to the frame and sliding in a third direction. The lifting device also includes a spacing adjustment mechanism for adjusting the distance between adjacent beam frames 10. In this embodiment, multiple lifting mechanisms can be installed in the frame, which can be used to lift containers in multiple carriages, further improving the turning efficiency. The beam frame 10 can be slidably connected to the frame body. Specifically, a T-slot or dovetail groove can be provided on either the beam frame 10 or the frame body, or a slider with a T-slot or dovetail groove can be provided, with a corresponding guide rail adapted to the T-slot or dovetail groove on the other component. Alternatively, a T-slot guide rail can be provided on one component, and a slot can be provided on the other component, with a guide wheel on the slot, allowing the guide wheel to roll in contact with the T-slot guide rail.

[0040] The spacing adjustment mechanism can be achieved by driving two adjacent beams 10 with a hydraulic cylinder or an electric cylinder. Alternatively, a rack and pinion mechanism or a linear motor can be used. The adjustable spacing is suitable for carriages of different lengths.

[0041] Furthermore, the lifting mechanism also includes a drive shaft connecting two adjacent beam frames 10. Each hoisting mechanism is connected to the drive shaft and shares a common drive source. To ensure that multiple hoisting mechanisms can synchronously drive and lift multiple sets of lifting frames, drive wheels 42 can be rotatably installed in the same area of ​​each beam frame 10 arranged side by side. The drive wheels 42 are connected by the same drive shaft and can be slidably connected to the drive shaft so that when the hoisting mechanism adjusts the spacing, the drive wheels 42 can slide along the drive wheels without jamming. The first motor can be installed on a beam frame 10 located at one end and driven by the drive shaft. To prevent loose material from adhering to the drive shaft, a corrugated pipe or telescopic pipe can be sleeved on the drive shaft, with both ends of the corrugated pipe or telescopic pipe respectively installed on two adjacent housings 11. The aforementioned drive wheels 42 and the first motor can be considered as the aforementioned hoisting mechanism. The first motor is the aforementioned drive source.

[0042] This application also proposes a tipping device, referring to... Figures 1 to 4 The tipping equipment includes the aforementioned lifting device. The lifting device is located in the frame. After the lifting device lifts and secures the container, it can tip over along with the frame to dump the bulk materials.

[0043] The above are only some or preferred embodiments of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
