Description

TECHNICAL FIELD

[0001] The present application relates to the field of carriage cleaning equipment, in particular to a lifting device for cleaning and collecting residual materials in a carriage, and to a cleaning and collecting device for residual materials in a carriage. BACKGROUND

[0002] In the production process, enterprises such as ports, power plants and mining and smelting will purchase a large amount of blocky or powdery mineral resources as production raw materials, such as coal. In bulk procurement, such bulk materials are mainly transported by trains or heavy trucks. During transportation, due to moisture and vibration, the bulk materials will generally adhere tightly to the carriage. After unloading, a part of the materials cannot be unloaded completely and will adhere to the bottom or side wall of the carriage to form residues, which need to be cleaned. Some cleaning devices in the prior art are provided with a negative pressure mechanism on the cleaning box or rack, a bottom brush mechanism for cleaning the bottom of the carriage, and two side cleaning mechanisms for simultaneously cleaning the two inner walls of the carriage. The following technical problems exist:

[0003] Firstly, the safety performance of the cleaning device in the prior art is not high. The cleaning box is lowered into the carriage by a crane through a winch for cleaning, and the cleaning box is lifted after cleaning is completed. The winch connects the cleaning box through a steel wire rope, and the cleaning box is lifted and lowered simultaneously. However, the steel wire rope connection shakes greatly, the cleaning difficulty is increased, and the safety reliability is not high.

[0004] Secondly, the overall adjustment freedom of the cleaning device in the prior art is single. The cleaning device can only be lifted and lowered by the winch, and the transmission time is long.

[0005] Thirdly, in the cleaning device in the prior art, the crane drives the cleaning box to move in the carriage for cleaning. There are two problems in the operation. Firstly, when the residual material has a large bonding strength, the cleaning box will be displaced immediately due to the obstruction of the residual material (because it is a flexible lifting), which causes an "avoidance" effect, so that the cleaning is not complete and the cleaning effect is poor. Secondly, when the residual material is large and has a great bonding strength, the cleaning box is blocked by the large residual material and cannot move, but the crane still drags the cleaning box to move, which will damage the equipment, and even cause a serious safety accident.

Detailed Implementation

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 9 As shown, this invention provides a lifting device for collecting and cleaning scrap materials from a vehicle compartment. It drives a cleaning box 9 to rise and fall above the vehicle compartment. The device includes two lifting mechanisms 1 and a hanging mechanism 2 connected between the two lifting mechanisms 1. It also includes multiple mounting seats 6, each with multiple mounting holes and matching mounting components. Both lifting mechanisms 1 are fixed to an external mobile frame 8 via the mounting seats 6 and mounting components to form a parking area for the vehicle compartment below the two lifting mechanisms 1. The hanging mechanism 2 is fixedly connected to the top of the cleaning box 9. The two lifting mechanisms 1 simultaneously drive the hanging mechanism 2 to descend, lowering the cleaning box 9 into the vehicle compartment below for cleaning. The specific implementation principle is as follows:

[0037] Taking a train carriage as an example, first, the first carriage (such as...) Figure 8 , Figure 9 As shown in Figure A), the device stops below the two lifting mechanisms 1. At this time, the hanging mechanism 2, along with the cleaning box 9, is in the raised state (as shown in Figure A). Figure 6 , Figure 8 (As shown in the diagram). Then, both lifting mechanisms 1 simultaneously drive the hanging mechanism 2 to descend, causing the cleaning box 9 to also descend and finally be placed in the lower compartment for cleaning (as shown in the diagram). Figure 7 , Figure 9(As shown in the diagram). In this embodiment, the mobile frame 8 has a moving function, enabling it to move the cleaning box 9 within the carriage for cleaning. After cleaning is completed, the two lifting mechanisms 1 simultaneously drive the hanging mechanism 2 to rise, causing the cleaning box 9 to also rise from within the carriage. Then the train continues to move, moving the second carriage to a position below the two lifting mechanisms 1; or the train does not move, the mobile frame 8 moves to the second carriage, and then the two lifting mechanisms 1 again simultaneously drive the hanging mechanism 2 to descend, causing the cleaning box 9 to descend again and finally fall into the carriage below for cleaning, thus repeating the cycle. That is, the lifting device for cleaning and collecting leftover materials in the carriage of the present invention is completely different from the previous overhead crane technology. Instead, a lifting mechanism 1 is set on both sides of the cleaning box 9, and then the lifting mechanism 1 drives the hanging mechanism 2 between them to raise and lower the cleaning box 9. This solves the problems of long lifting stroke, long force transmission time, and large lifting sway caused by the winch lifting method, so that the cleaning box 9 can be quickly and smoothly placed in the carriage for cleaning, making the cleaning operation faster, the cleaning effect better, and the safety greatly improved.

[0038] Furthermore, in a preferred embodiment, the lifting mechanism 1 includes a fixed frame 11, within which a sliding frame 12 that can slide up and down and a vertically arranged drive cylinder 13 are provided. The drive cylinder 13 drives the sliding frame 12 to rise and fall within the fixed frame 11. The sliding frame 12 also includes a synchronization component 15 and a sliding carriage 14 that can slide up and down. The carriage 14 is fixedly connected to the hanger mechanism 2. The synchronization component 15 is connected to the carriage 14 to synchronize the movement of the carriage 14 within the sliding frame 12 when the sliding frame 12 rises and falls within the fixed frame 11. The frame structure of the fixed frame 11 and the sliding frame 12 ensures structural stability and high strength, effectively guaranteeing the implementation of the lifting mechanism. Meanwhile, this invention features a two-stage, two-section lifting mechanism, which allows for a large lifting stroke and reduces the overall height, making it extremely convenient for the installation and use of the sweeping box 9, which has a certain height. It also reduces the stroke of the drive cylinder 13. In this embodiment, the drive cylinder 13 is a hydraulic cylinder, which drives itself for 1.2 meters, and the lifting mechanism 1 can lift the sweeping box 9 2.4 meters. More importantly, the two-stage lifting mechanism, through the synchronization component 15, enables simultaneous lifting at both stages. This further shortens the lifting time. In this embodiment, the hydraulic cylinder drives itself for 1.2 meters, and the lifting mechanism 1 can lift the sweeping box 9 2.4 meters, doubling the operating speed and greatly improving work efficiency. Secondly, it further reduces the complexity of the structure and lowers manufacturing and maintenance costs.

[0039] Further, in the preferred embodiment, the fixed frame 11 comprises two vertically arranged first slide rail rods 111, and the bottom of the sliding frame 12 is provided with a first sliding block 121 which is in sliding fit with the first slide rail rod 111 and is limitingly installed between the two first slide rail rods 111 for enabling the sliding frame 12 to slide up and down. Figure 2 As shown in FIG. 4, the driving cylinder 13 is retracted downward, and the sliding frame 12 is pulled to retract downward along the first slide rail rod 111, thereby realizing the descending and enabling the fixed frame 11 and the sliding frame 12 to be folded together. Figure 3 As shown in FIG. 4, the driving cylinder 13 is retracted downward, and the sliding frame 12 is pulled to retract downward along the first slide rail rod 111, thereby realizing the descending and enabling the fixed frame 11 and the sliding frame 12 to be folded together.

[0040] Further, in the preferred embodiment, the sliding frame 12 comprises two vertically arranged second slide rail rods 122, and the two sides of the sliding carriage 14 are provided with a second sliding block 141 which is in sliding fit with the second slide rail rod 122 and is limitingly installed between the two second slide rail rods 122 for enabling the sliding carriage 14 to slide up and down. The two vertically arranged first slide rail rods 111 constitute the two side frames of the fixed frame 11, and the two vertically arranged second slide rail rods 122 constitute the two side frames of the sliding frame 12, which reduces the manufacturing cost and makes the structure simple and stable.

[0041] Further, in the preferred embodiment, the bottom of the two second slide rail rods 122 is connected through a connecting plate 123, and the top is connected through a top plate 124. The synchronous assembly 15 comprises a chain 151 and a sprocket 152 which are engaged with each other. The sprocket 152 is rotatably fixed to the top plate 124 through a mounting piece. The vertically arranged chain 151 is fixed at one end to the connecting plate 123 and is fixedly connected at the other end to the sliding carriage 14 after being wound around the sprocket 152, for enabling the sliding carriage 14 to be pulled to rise synchronously by the chain 151 when the sliding frame 12 rises.

[0042] As shown in FIG. 4, the driving cylinder 13 is retracted downward, and the sliding frame 12 is pulled to retract downward along the first slide rail rod 111, thereby realizing the descending and enabling the fixed frame 11 and the sliding frame 12 to be folded together. Figure 2 As shown in FIG. 4, the driving cylinder 13 is retracted downward, and the sliding frame 12 is pulled to retract downward along the first slide rail rod 111, thereby realizing the descending and enabling the fixed frame 11 and the sliding frame 12 to be folded together. Figure 3As shown, when the driving cylinder 13 is retracted downward, the sliding frame 12 is pulled to retract along the first sliding rail 111 downward, at this time, the horizontal position of the sprocket 152 on the top of the sliding frame 12 will inevitably also drop, and the slide frame 14 will also drop synchronously under the action of its own gravity because it is no longer pulled upward by the chain 151. In this embodiment, two sprockets 152 and two parallel chains 151 are provided, and the pulling effect is better. This structure design is simple and compact, greatly reducing the manufacturing and maintenance costs and saving equipment space. Second, the synchronization effect is good, the lifting stroke is short, the transmission time is short, the cleaning operation is fast, and the work efficiency is improved.

[0043] Further, in the preferred embodiment, the upper and lower ends of the fixed frame 11 are respectively provided with upper and lower limit switches 112 and 113, and the upper and lower limit switches 112 and 113 are in communication connection with the driving cylinder 13 for controlling the driving stroke of the driving cylinder 13. For example, when the upper limit switch 112 senses that the sliding frame 12 has risen to the position, the driving cylinder 13 stops driving upward.

[0044] Further, in the preferred embodiment, the cleaning box 9 is provided with a self-adaptive positioning mounting mechanism 5 for mounting on the side wall of the carriage after the cleaning box 9 falls down, the hanger mechanism 2 flexibly hoists the cleaning box 9 on the hanger mechanism 2 through the lifting rope, and a plurality of push rods 22 are arranged on the hanger mechanism 2 around the cleaning box 9 for pushing the cleaning box 9 to move when the hanger mechanism 2 moves horizontally, and the push rod 22 is arranged on the pressure sensor alarm 23 for real-time monitoring of the pushing force and alarming when the preset value is reached.

[0045] Due to a little error in different car widths, the adaptive positioning and hanging mechanism 5 can make the cleaning box 9 adapt to the width of the car and successfully hang on the car, ensuring that the cleaning box 9 is always in the middle of the car, thereby ensuring excellent cleaning effect. In order to ensure adaptive position adjustment, the cleaning box 9 is flexibly hoisted on the hanging bracket mechanism 2 by a lifting rope. However, flexible hoisting may also cause the problem in the prior art described in the third point in the background technology. Therefore, the present application further provides a plurality of push rods 22 around the cleaning box 9. When the hanging bracket mechanism 2 moves horizontally, the push rods 22 push the cleaning box 9 to move together, rather than pulling the cleaning box 9 to move by the lifting rope. The push rods 22 push the cleaning box 9 to move, which is a hard contact, can better transmit force and save time. And the push rods 22 are arranged on the pressure sensing alarm 23. When the cleaning box 9 encounters general strength of residual material obstacles, the plurality of push rods 22 will push the cleaning box 9 to continue to move forward, so that the cleaning is thorough and the cleaning effect is good; when the cleaning box 9 is blocked by a large piece of residual material and the pressure sensing alarm 23 detects that the pushing force of the push rod 22 reaches a preset value, the pressure sensing alarm 23 sends an alarm, and the moving rack 8 stops driving the cleaning box 9 to move, effectively protecting the equipment and improving the work safety.

[0046] Further, in the preferred embodiment, a plurality of lifting ring rods 21 are arranged on the hanging bracket mechanism 2 for fixing the lifting rope. One end of the lifting ring rod 21 fixed to the hanging bracket mechanism 2 is provided with a threaded portion for fine adjustment of the hoisting height of the cleaning box 9 by rotating. In this embodiment, the lifting ring rod 21 is screwed on the hanging bracket mechanism 2 and fixed by a nut. By adjusting the screwing length of the lifting ring rod 21, the hoisting height of the cleaning box 9 can be fine adjusted.

[0047] As shown in Figure 6 , Figure 7 , Figure 8 , Figure 9 On the basis of the above disclosed technical features and technical embodiments, the present application further provides a car residual material cleaning and collecting device, comprising a moving rack 8 and a cleaning box 9. The cleaning box 9 is installed on the moving rack 8 by the lifting device for cleaning and collecting car residual material according to any one of the above. The cleaning lifting is stable, the cleaning operation is fast, the cleaning effect is good, and the safety is greatly improved.

[0048] Although the present application has been disclosed with reference to the preferred embodiments, it is not intended to limit the present application. Any person skilled in the art, without departing from the technical scope of the present application, can make many possible changes and modifications to the disclosed technical content of the present application, or modify equivalent embodiments of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments without departing from the technical content of the present application, according to the technical essence of the present application, shall fall within the scope of protection of the present application.
