Abstract
Description
Technical Field
[0001] This utility model relates to the field of scraping equipment technology, and in particular to a floating multi-stage electric cylinder scraping device, and a scraping trolley using the floating multi-stage electric cylinder scraping device. Background Technology
[0002] In the metallurgical industry, materials falling under conveyor belts due to vibration are usually recovered and cleaned up manually by shoveling. However, for safety reasons, cleaning personnel cannot work under the equipment while the conveyor belt is running, resulting in a large accumulation of material under the conveyor belt that cannot be cleared in time. When the equipment is shut down for a short time, the task of cleaning up the material on site is heavy. In addition, the manual shoveling method is inefficient, and each cleaning requires a lot of personnel.
[0003] In addition, due to the narrow space under the conveyor belt, even if cleaning personnel enter under the equipment, they cannot completely remove the fallen materials with shovels. Moreover, the on-site working environment is extremely harsh. It is necessary to minimize the working time of personnel under the conveyor belt to prevent accidents caused by falling materials. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a floating multi-stage electric cylinder scraping device that can achieve efficient and automated material cleaning and reduce the workload of manual labor.
[0005] The present invention adopts the following technical solution:
[0006] This utility model provides a floating multi-stage electric cylinder scraping device, including a multi-stage telescopic electric cylinder, a fixed plate, a baffle, and a scraper. The multi-stage telescopic electric cylinder is horizontally arranged and vertically connected to the fixed plate through its telescopic end. The baffle is arranged on the side of the fixed plate away from the multi-stage telescopic electric cylinder and is parallel to the fixed plate. A gap is reserved between the baffle and the fixed plate. The scraper is arranged in the gap between the baffle and the fixed plate and can move freely up and down in the vertical direction.
[0007] Preferably, the multi-stage telescopic electric cylinder is a three-stage telescopic electric cylinder.
[0008] Preferably, the horizontal longitudinal lengths of the fixed plate and the baffle are equal, the horizontal longitudinal length of the scraper is 10mm shorter than that of the fixed plate, and the thickness of the scraper is 1mm smaller than the distance between the baffle and the fixed plate.
[0009] Preferably, the scraper has a U-shaped groove extending vertically in the middle position, and a guide rod is vertically connected in the gap between the baffle and the fixed plate, and the guide rod passes through the U-shaped groove.
[0010] This utility model also provides a scraping cart, including a car body, a lifting frame, and a floating multi-stage electric cylinder scraping device as described in any one of the above. The lifting frame is movably mounted at the head end of the car body. The multi-stage telescopic electric cylinder on the floating multi-stage electric cylinder scraping device is fixedly connected to the lifting frame through a fixed end, and both the lifting frame and the multi-stage telescopic electric cylinder are connected to the control system signal of the car body.
[0011] Preferably, two floating multi-stage electric cylinder scraping devices are symmetrically arranged on the lifting frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] When using the floating multi-stage electric cylinder scraping device of this utility model, the fixed end of the multi-stage telescopic electric cylinder needs to be installed on a lifting vehicle with lifting function so that the lifting vehicle can be used to lift the entire device.
[0014] When using the floating multi-stage electric cylinder scraping device of this utility model for formal material cleaning operations, the device is first raised to a certain height by a lifting vehicle, and then the multi-stage telescopic electric cylinder is extended outward to the correct position. Then, the lifting vehicle drives the device to continue to descend. During the descent, the scraper first contacts the ground and moves upward within the gap as the device continues to descend. After the device descends to the correct position, the bottom of the scraper is completely in contact with the ground, while the baffle and the fixed plate are still a certain distance from the ground. After that, controlling the retraction of the multi-stage telescopic electric cylinder will drive the scraper to scrape the material on the ground, achieving efficient and automated material cleaning and reducing the workload of manual labor.
[0015] Meanwhile, the floating multi-stage electric cylinder scraping device of this utility model, due to the floating setting of the scraper plate, can always automatically keep in contact with the ground without being affected by the ground height, and scrape the material cleanly; and even if the ground is uneven or the material pile is uneven, the scraper plate will automatically float up and down, so that no reaction force is transmitted to the multi-stage telescopic electric cylinder, and the service life of the multi-stage telescopic electric cylinder is not affected.
[0016] The scraper cart of this utility model naturally possesses the aforementioned beneficial effects due to the adoption of the above-mentioned floating multi-stage electric cylinder scraper device, which will not be elaborated further here. Attached Figure Description

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.
[0024] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 mechanical connection or an electrical 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 utility model according to the specific circumstances.
[0026] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0027] See Figure 1 This embodiment provides a floating multi-stage electric cylinder scraping device, including a multi-stage telescopic electric cylinder 1, a fixed plate 2, a baffle 3, and a scraper 4. The multi-stage telescopic electric cylinder 1 is horizontally arranged and vertically connected to the fixed plate 2 through its telescopic end. The baffle 3 is arranged on the side of the fixed plate 2 away from the multi-stage telescopic electric cylinder 1 and is parallel to the fixed plate 2. A gap is reserved between the baffle 3 and the fixed plate 2. The scraper 4 is arranged in the gap between the baffle 3 and the fixed plate 2 and can be freely raised and lowered in the vertical direction.
[0028] It should be noted that when using the floating multi-stage electric cylinder scraping device of this embodiment, the fixed end of the multi-stage telescopic electric cylinder 1 needs to be installed on a lifting vehicle with lifting function so that the lifting vehicle can be used to lift the entire device.
[0029] When using the floating multi-stage electric cylinder scraper device of this embodiment for formal material cleaning operations, the device is first raised to a certain height by a lifting vehicle, and then the multi-stage telescopic electric cylinder 1 is controlled to extend outward to the correct position. Then, the lifting vehicle drives the device to continue to descend. During the descent, the scraper 4 first contacts the ground and moves upward within the gap as the device continues to descend. After the device descends to the correct position, the bottom of the scraper 4 is completely in contact with the ground, while the baffle 3 and the fixed plate 2 are still a certain distance from the ground. After that, controlling the multi-stage telescopic electric cylinder 1 to retract will drive the scraper 4 to scrape the material on the ground, achieving efficient and automated material cleaning and reducing the workload of manual labor.
[0030] Meanwhile, the floating multi-stage electric cylinder scraping device of this embodiment, due to the floating setting of the scraper plate 4, can always automatically keep in contact with the ground without being affected by the ground height, and scrape the material cleanly; and even if the ground has height changes due to unevenness, or the material pile has height changes, the scraper plate 4 will automatically float up and down, so that it will not transmit the reaction force to the multi-stage telescopic electric cylinder 1, and will not affect the service life of the multi-stage telescopic electric cylinder 1.
[0031] Preferably, in this embodiment, the telescopic end of the multi-stage telescopic electric cylinder 1 is vertically connected to the fixed plate 2 by fasteners.
[0032] Preferably, the multi-stage telescopic electric cylinder 1 is a 3-stage telescopic electric cylinder. The telescopic ratio of the 3-stage telescopic electric cylinder is 3, which enables the floating multi-stage electric cylinder scraping device of this embodiment to drive the scraper plate 4 to perform a large-area cleaning operation with a relatively small electric cylinder installation size.
[0033] Preferably, the horizontal longitudinal lengths of the fixed plate 2 and the baffle 3 are equal, the horizontal longitudinal length of the scraper 4 is 10mm shorter than the horizontal longitudinal length of the fixed plate 2, and the thickness of the scraper 4 is 1mm smaller than the gap between the baffle 3 and the fixed plate 2, so that the scraper 4 can be accommodated in the gap between the baffle 3 and the fixed plate 2 in the horizontal longitudinal direction, preventing the material from directly contacting the scraper 4 in the horizontal longitudinal direction, and avoiding the scraper 4 from being unable to move freely in the vertical direction due to increased friction.
[0034] Preferably, in this embodiment, the horizontal longitudinal length of both the fixed plate 2 and the baffle 3 is 900mm, the distance between the baffle 3 and the fixed plate 2 is 6mm, the horizontal longitudinal length of the scraper 4 is 890mm, and the thickness of the scraper 4 is 5mm, so as to better adapt to the conveyor belt on site, and all the materials spilled under the conveyor belt can be cleaned up at the same time through one cleaning operation.
[0035] Preferably, see Figure 1 The scraper 4 has a U-shaped groove (not shown in the figure) extending vertically in the middle position. A guide rod (not shown in the figure) is vertically connected in the gap between the baffle 3 and the fixing plate 2, and the guide rod passes through the U-shaped groove.
[0036] It should be noted that the U-shaped groove combined with the guide rod can provide guidance for the lifting and lowering movement of the scraper 4, allowing the scraper 4 to rise and fall freely in the vertical direction.
[0037] This embodiment also provides a scraping vehicle, including a vehicle body, a lifting frame, and the above-mentioned floating multi-stage electric cylinder scraping device. The lifting frame is movably mounted at the head end of the vehicle body. The multi-stage telescopic electric cylinder 1 on the floating multi-stage electric cylinder scraping device is fixedly connected to the lifting frame through a fixed end, and both the lifting frame and the multi-stage telescopic electric cylinder 1 are connected to the control system signal of the vehicle body.
[0038] When using the scraper truck of this embodiment to clean up materials spilled under the conveyor belt, the vehicle's control system can simultaneously control the lifting frame and the multi-stage telescopic electric cylinder 1, thereby completing the lifting and telescopic movements of the scraper plate 4.
[0039] Preferably, two floating multi-stage electric cylinder scraping devices are symmetrically arranged on the lifting frame. During operation, the scraping vehicle controls the multi-stage telescopic electric cylinders 1 on the two floating multi-stage electric cylinder scraping devices to extend outward simultaneously. During the subsequent descent of the scraper plates 4, even if the distance between the scraper plates 4 on the two floating multi-stage electric cylinder scraping devices and the ground is inconsistent, the bottom of the two scraper plates 4 can still eventually contact the ground. Furthermore, the baffles 3 and fixed plates 2 on the two floating multi-stage electric cylinder scraping devices are still a certain distance from the ground. Thus, the material accumulated on the ground under the two conveyor belts is scraped off simultaneously by the retraction of the multi-stage telescopic electric cylinders 1, achieving efficient material cleaning operation.
[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
