Description

Technical Field

[0001] This utility model relates to a lifting support fixture, and more particularly to a lifting support fixture for an auxiliary material cart. Background Technology

[0002] In tobacco processing production lines, storage bins play a crucial role. As an important piece of equipment, they are responsible for storing raw materials such as tobacco leaves, stems, and shredded tobacco, playing an indispensable role in ensuring balanced production, moistening tobacco leaves, and uniform moisture content. Currently, most common storage bin equipment adopts a side-chain transmission structure. The entire storage bin is mainly composed of components such as a feeding cart, frame, rollers, side-chain belt, feeding rollers, cleaning rollers, and a transmission device.

[0003] Driven by a reducer, the material spreading trolley, supported by its wheels, moves in a step-by-step motion along the track above the storage tank, evenly distributing the material transported by the reciprocating concrete placing machine in a pile-like manner within the tank's interior space. This ensures proper material storage and the smooth operation of subsequent processes. However, because the spreading trolley needs to reciprocate on the track for extended periods, its wheels inevitably face numerous malfunctions. Prolonged friction and mechanical movement make the wheels prone to wear, affecting not only their normal rolling but also potentially reducing operational accuracy. Furthermore, wheel slippage is also a frequent occurrence, threatening the overall operational stability of the spreading trolley. Additionally, bearings, as critical components for wheel operation, are also susceptible to damage under long-term load operation, further impacting the normal functioning of the wheels.

[0004] In light of the aforementioned malfunction of the traveling wheels, to ensure the normal operation of the material laying vehicle and, consequently, the stable operation of the entire storage tank system, it is necessary to regularly maintain and replace the traveling wheels of the material laying vehicle. During maintenance and replacement, due to the special installation position of the traveling wheels and their relationship with the rails, the material laying vehicle must be lifted so that the entire traveling wheel is higher than the storage tank rails in order to smoothly carry out the relevant maintenance work.

[0005] The material laying trolley itself measures 13800mm x 3404mm, a massive size that results in significant weight. More importantly, the trolley was not designed with a dedicated jack support. This means that during maintenance, workers must use pry bars and other tools to lift the trolley before carrying out the necessary work. This method has several drawbacks. First, the maintenance process requires multiple workers, consuming considerable manpower and creating difficulties in coordination, potentially leading to inconsistencies and reduced efficiency. Second, the storage tank's dimensions are 27803mm x 3925mm x 4058mm, meaning maintenance workers are typically working at heights. Using pry bars to lift the trolley poses a significant safety hazard, potentially causing accidents and seriously endangering worker safety. Utility Model Content

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Embodiments of this utility model: such as Figure 1 As shown, a lifting support fixture for an auxiliary material cart includes a support frame, which includes a fixed clamping plate 1, a movable clamping plate 2, and a support plate 3. A connecting top plate 4 is fixedly provided at the top of the fixed clamping plate 1. The top of the movable clamping plate 2 is rotatably connected to the connecting top plate 4. The lower end of the movable clamping plate 2 is connected to the lower end of the fixed clamping plate 1 through a connector. The support plate 3 is connected to the fixed clamping plate 1 through a transition bracket. A handle 15 is fixedly provided at the top of the connecting top plate 4.

[0020] In use, the fixed clamp 1 is fitted against the inner wall of the track, the bottom surface of the connecting top plate 4 is fitted against the top surface of the track, the movable clamp 2 is flipped to fit against the outer wall of the track, and then the movable clamp 2 is connected to the fixed clamp 1 with the connector to fix the entire fixture on the track. The transition bracket serves to avoid the inner structure of the track. Then the jack is placed on the support plate 3 and the jack is used to lift one side of the auxiliary material cart. Only one worker is needed to complete the maintenance of the auxiliary material cart.

[0021] In this embodiment, the fixed clamping plate 1, the movable clamping plate 2, the transition bracket, the support plate 3, and the connecting top plate 4 are preferably made of high-quality steel plate with a thickness of 8mm. Of course, steel plates of other thicknesses can also be selected according to actual needs.

[0022] Specifically, the transition support includes a horizontal transition plate 5 and a vertical transition plate 6. One end of the horizontal transition plate 5 is fixedly connected to the fixed clamping plate 1, and the other end of the horizontal transition plate 5 is fixedly connected to the top of the vertical transition plate 6. One end of the support plate 3 is fixedly connected to the bottom of the vertical transition plate 6.

[0023] The fixed clamping plate 1 is set vertically, and the transverse transition plate 5 is perpendicular to the fixed clamping plate 1. The transverse transition plate 5 is welded and fixed to the upper middle part of the fixed clamping plate 1. To improve structural strength, the transverse transition plate 5 is connected to the fixed clamping plate 1 by two second diagonal braces 8. The lower end of the second diagonal brace 8 is welded and fixed to the end of the transverse transition plate 5 away from the fixed clamping plate 1, and the other end of the second diagonal brace 8 is welded and fixed to the top of the fixed clamping plate 1. The second diagonal braces 8 effectively prevent the transverse transition plate 5 from bending and deforming.

[0024] The fixed clamp 1 and the movable clamp 2 are the same size, and the height of both is greater than the height of the track. The width of the connecting top plate 4 is equal to the width of the track.

[0025] The top surface of the vertical transition plate 6 is welded and fixed to the end of the horizontal transition plate 5 away from the fixed clamping plate 1. The vertical transition plate 6 is perpendicular to the horizontal transition plate 5, that is, the vertical transition plate 6 is parallel to the fixed clamping plate 1. The horizontal transition plate 5 serves to avoid other structures inside the track in the horizontal direction, such as the side beams of the storage tank. The vertical transition plate 6 is used to allow the jack to be placed under the auxiliary material cart. Since the jack has a certain height, if the vertical transition plate 6 is not installed, the distance between the support plate 3 and the bottom of the auxiliary material cart will be too small to place the jack.

[0026] The support plate 3 is horizontally positioned, with one end welded and fixed to the lower end of the vertical transition plate 6. The support plate 3 is perpendicular to the vertical transition plate 6. Similarly, to improve the strength of the support plate 3, it is also connected to the vertical transition plate 6 by two first diagonal braces 7. One end of each first diagonal brace 7 is welded and fixed to the end of the support plate 3 away from the vertical transition plate 6, and the other end is welded and fixed to the upper end of the vertical transition plate 6.

[0027] The two first diagonal tie rods 7 not only improve the structural strength of the support plate 3, but also limit the jack and prevent it from accidentally slipping off the support plate 3. In order to prevent the jack from slipping off, this embodiment also fixes a baffle 14 at the end of the support plate 3 away from the vertical transition plate 6.

[0028] Furthermore, the connecting top plate 4 is perpendicular to the fixed clamping plate 1, and two first mounting tubes 9 are fixedly provided at the end of the connecting top plate 4 away from the fixed clamping plate 1. A second mounting tube 10 is fixedly provided at the upper end of the movable clamping plate 2. The second mounting tube 10 is located between the two first mounting tubes 9, and the second mounting tube 10 and the two first mounting tubes 9 are connected by a rotating shaft.

[0029] The lower end of the fixed clamping plate 1 has two opening slots 11. The connecting parts include threaded rods 12 and locking nuts 13. The lower end of the movable clamping plate 2 is provided with two rotating shafts. Threaded rods 12 are rotatably connected to the two rotating shafts respectively. The positions of the two threaded rods 12 are opposite to the positions of the two opening slots 11. Locking nuts 13 are threadedly connected to the two threaded rods 12 respectively.

[0030] The working principle of this utility model is as follows: When in use, the operator moves this tooling between the two tracks of the auxiliary material cart. First, the movable clamp 2 is flipped to a horizontal state. Then, the tooling is placed on the track so that the inner side wall of the fixed clamp 1 is in contact with the track and the connecting top plate 4 is in contact with the top surface of the track. Then, the movable clamp 2 is flipped so that it is in contact with the outer side wall of the track. Since the height of the fixed clamp 1 and the movable clamp 2 is greater than the height of the track, when the connecting top plate 4 is in contact with the top surface of the track, the bottom surfaces of the fixed clamp 1 and the movable clamp 2 are lower than the bottom surface of the track.

[0031] At this point, you can hold the handle 15 and move the entire tooling to the position where the auxiliary material cart needs to be lifted. Then rotate the two threaded rods 12 so that the two threaded rods 12 are respectively inserted into the two open slots 11 at the bottom of the fixed clamping plate 1. Tighten the two locking nuts 13, and the fixed clamping plate 1 and the movable clamping plate 2 clamp the track. At this point, the tooling is effectively fixed on the track.

[0032] Place the jack on the support plate 3. The jack has first diagonal tie rods 7 on both sides, a baffle 14 on the front, and a vertical transition plate 6 on the rear, so there's no need to worry about the jack slipping off the support plate 3. Use the jack to lift the side of the auxiliary material cart that needs maintenance, and the workers can begin the maintenance work.

[0033] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
