Technical Field

[0001] The utility model relates to a steel plate storage device for port and wharf construction, in particular to a steel plate storage device for port and wharf construction applied in the technical field of wharf construction equipment. Background Art

[0002] During the construction of ports and terminals, a large number of steel plates are often needed for ground paving, retaining wall construction and other projects. Steel plates are usually large in size and heavy in weight. Manual handling and stacking are not only time-consuming and labor-intensive, but also pose certain safety hazards. Therefore, how to achieve efficient and safe storage and use of steel plates has become an urgent problem to be solved in port and terminal construction.

[0003] Chinese invention patent CN102836930B discloses a steel plate stacker, which realizes automatic stacking of steel plates through multiple split slider mechanisms and cylinder drive. The design adopts a split structure, which reduces the processing difficulty, reduces the cost, and improves the overall technical level of the steel coil flattening production line. However, the design is mainly aimed at the steel coil flattening production line, and lacks pertinence and adaptability for port terminal construction sites. The port terminal construction environment is complex, and the steel plate specifications are diverse, so a steel plate storage device specifically for port construction is needed.

[0004] Chinese invention patent CN111362005B discloses a new type of automatic adjustment device for the production, storage and arrangement of high-strength steel plates. Through the transmission mechanism such as the driving wheel and the driven wheel in conjunction with the spring, the automatic adjustment and arrangement of the stacking height of the steel plates is realized. This design has the advantages of automatic height adjustment and automatic arrangement, and reduces manual operation. However, this design adopts multi-stage transmission and has a relatively complex structure, which is suitable for fixed production workshops. For the port terminal construction site, a steel plate storage device with a simple structure and easy to move is needed.

[0005] The above design realizes automatic stacking and height adjustment of steel plates through mechanical transmission, which solves the problem of steel plate storage to a certain extent, but there are still certain limitations, such as complex structure, poor applicability, low mobility, etc. Port terminal construction requires a steel plate storage device designed specifically for its construction characteristics and environmental requirements to achieve efficient storage and retrieval of steel plates and reduce labor costs and safety hazards.

[0007] In order to solve the above problems, the utility model provides a steel plate storage device for port terminal construction, including a base, a column fixedly connected to the top end of the base, a buffer groove is opened in the column, a counterweight box is slidably connected in the buffer groove, a first storage box and a second storage box are fixedly connected to the outer end of the column, a first lifting plate and a second lifting plate are slidably connected in the first storage box and the second storage box respectively, the tops of the first lifting plate and the second lifting plate are both contacted with steel plates, a steel rope is provided between the column and the bottom end of the counterweight box, and one end of the steel rope away from the counterweight box passes between the first storage box and the first lifting plate, and the other end passes between the second storage box and the second lifting plate, and both ends of the steel rope extend to the outside of the first storage box and the second storage box.

[0008] As a further improvement of the present application, a first pulley is provided between the top end of the column, the bottom end of the counterweight box, the bottom end of the first lifting plate, the bottom end of the second lifting plate and the steel rope, and the first pulley is rotatably connected to the corresponding column, counterweight box, first lifting plate, second lifting plate and steel rope respectively.

[0011] As another improvement of the present application, the top end of the adjusting screw is fixedly connected to the steel rope, the outer end of the adjusting screw is threadedly connected to an adjusting nut, and the adjusting nut is abutted against the bottom end of the adjusting plate.

[0012] As another improvement supplement to the present application, a counterweight chamber is provided in the counterweight box, the counterweight chamber is filled with water, a water inlet pipe is fixedly connected to the top end of the counterweight box, a drainage pipe is fixedly connected to the bottom end of the counterweight box, brackets are fixedly connected to both ends of the first pulley shaft, and a plurality of ribs are fixedly connected to the inner wall of the column near one end of the counterweight box.

[0018] 3. Height adjustment: By adjusting the nut to change the effective length of the steel rope, the lower limit of the lifting plate can be flexibly adjusted to meet the storage needs of different heights. The adjustment operation is simple and convenient, which improves the applicability of the device.

[0019] 4. Balanced placement: The symmetrical arrangement of the first and second storage boxes and the lifting plate ensures that the steel plate is balanced when placed, with the top flat and not prone to tilting or collapsing. At the same time, the balanced gravity transfer also makes the lifting of the counterweight box more stable and controllable.

[0020] 5. Buffer design: A buffer groove is set inside the column, and the counterweight box slides inside it, which can effectively buffer the impact during starting and stopping, making the device run more smoothly. Various rotating parts such as pulleys are also equipped with brackets to improve the stability and reliability of the device.

[0021] 6. Save space; the storage box adopts a lifting design and can be lowered to the lowest position when not in use, saving site space. The counterweight in the counterweight box can also be flexibly adjusted by filling and draining water without taking up extra space.

[0022] 7. Easy to move: The counterweight box is filled with water, using the water source near the dock, and there is no need to carry additional counterweights. Drain the water after use to reduce the weight of the device, making it easier to move and transport.

[0023] 8. Economical and practical; the device has a simple structure, low manufacturing and maintenance costs, and saves external power by utilizing the principle of gravity balance. It is economical and practical. For busy dock construction sites, it can significantly improve the efficiency of steel plate storage and retrieval and reduce labor costs.

[0034] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figure 1-Figure 8 Shown.

[0037] A steel plate storage device for port terminal construction includes a base 1, a column 2 is fixedly connected to the top of the base 1, a buffer groove 3 is opened in the column 2, a counterweight box 4 is slidably connected in the buffer groove 3, a first storage box 5 and a second storage box 6 are fixedly connected to the outer end of the column 2, a first lifting plate 7 and a second lifting plate 8 are respectively slidably connected in the first storage box 5 and the second storage box 6, the tops of the first lifting plate 7 and the second lifting plate 8 are both contacted with steel plates, a steel rope 9 is provided between the column 2 and the bottom end of the counterweight box 4, and one end of the steel rope 9 away from the counterweight box 4 passes between the first storage box 5 and the first lifting plate 7, and the other end passes between the second storage box 6 and the second lifting plate 8, and both ends of the steel rope 9 extend to the outside of the first storage box 5 and the second storage box 6.

[0038] The base 1 is a rectangular plate structure used to support the entire device. The column 2 is vertically fixed at the top center of the base 1 and adopts a hollow rectangular tubular structure. The material can be stainless steel or other high-strength, corrosion-resistant metal materials. A through buffer groove 3 is opened inside the column 2. The cross-sectional dimension of the buffer groove 3 is slightly larger than the cross-sectional dimension of the counterweight box 4, so that the counterweight box 4 can slide freely in the buffer groove 3.

[0039] The counterweight box 4 is a hollow rectangular box, and a counterweight chamber 15 is provided inside, and water or other liquids can be injected as counterweights. The counterweight box 4 is slidably connected in the buffer tank 3, and the weight of the steel plate can be balanced by adjusting the amount of liquid in the counterweight box 4.

[0040] The first storage box 5 and the second storage box 6 are symmetrically fixed on the outer surface of the column 2 and are distributed on the left and right. The storage box adopts a rectangular box structure, and the internal space is used to store steel plates. The first lifting plate 7 and the second lifting plate 8 are slidably connected in the first storage box 5 and the second storage box 6, respectively, for placing the steel plates to be stored. The top surface of the lifting plate is flush with the top surface of the storage box, which is convenient for placing the steel plates.

[0041] One end of the steel rope 9 is connected to the top of the column 2, and the other end is connected to the bottom of the counterweight box 4. After being led out from the top of the column 2, the steel rope 9 is divided into two strands, which respectively pass through the gap between the first storage box 5 and the first lifting plate 7, and the gap between the second storage box 6 and the second lifting plate 8, and finally the two ends extend to the outside of the storage box. The steel rope 9 can be made of a high-strength and flexible material, such as a steel wire rope or a nylon rope.

[0042] When in use, first inject a proper amount of water into the counterweight box 4, so that the counterweight box 4 sinks to the bottom of the column 2. At this time, under the pulling action of the steel rope 9, the first lifting plate 7 and the second lifting plate 8 rise to the highest position, flush with the top surface of the storage box. Then the steel plates to be stored are placed alternately on the first lifting plate 7 and the second lifting plate 8. As the weight of the steel plates increases, the counterweight box 4 is lifted, driving the lifting plate to descend, and the steel plates are automatically stored. When taking the steel plates, as the weight of the steel plates decreases, the counterweight box 4 sinks and the lifting plate rises, so that the steel plates are automatically raised to a suitable position for easy access.

[0043] Through the cooperation of the counterweight box 4 and the steel rope 9, the automatic storage of the steel plate is realized by utilizing the principle of gravity balance. When placing the steel plate, the counterweight box 4 is lifted, driving the lifting plate to descend; when taking the steel plate, the counterweight box 4 sinks, driving the lifting plate to ascend. No manual handling is required, saving time and effort.

[0044] A buffer groove 3 is provided in the column 2 to make the lifting and lowering of the counterweight box 4 more stable and reduce the start-stop impact. The counterweight in the counterweight box 4 can be flexibly adjusted, and the counterweight can be changed by filling and draining water to accurately balance the weight of the steel plate, making the storage process more controllable.

[0045] The first storage box 5 and the second storage box 6 are arranged symmetrically, and the first lifting plate 7 and the second lifting plate 8 are provided correspondingly. The steel plates are placed alternately and the force is evenly applied, which ensures the stability of the storage process and prevents the steel plates from tilting or sliding.

[0046] The storage box adopts a lifting design, and the lifting plate can sink to the bottom of the storage box when not in use, which takes up little space. The counterweight box 4 is placed inside the column 2, which does not take up extra space, and the entire device has a compact structure.

[0047] The device has a simple structure and its working principle is easy to understand. Placing and taking out the steel plate only requires manual movement of the steel plate onto the lifting plate or taking it off the lifting plate. The process is simple and convenient without complicated operations.

[0048] The device can be applied to steel plates of various specifications and sizes, and can match steel plates of different weights by adjusting the counterweight in the counterweight box 4. At the same time, the size of the storage box and the lifting plate can be flexibly adjusted according to actual needs to adapt to different storage capacities.

[0049] In addition to water, other liquid media, such as oil, sand, etc., can be used in the counterweight box 4, which can be selected according to actual conditions. Block or granular solid materials can also be used as counterweights, but a suitable loading and unloading mechanism needs to be set up, and the column 2 can be designed as a multi-section splicing structure to facilitate the transportation and installation of the device. The cross-sectional shape of the column 2 can also be optimized according to actual conditions, such as changing to a round tube, an octagonal tube, etc., to improve the force-bearing performance of the column 2, and the number of storage boxes and lifting plates can be increased according to actual needs to improve the storage efficiency. For example, three or four storage boxes are set, and three or four lifting plates are correspondingly set. The steel plates can be placed on each lifting plate in turn for cyclic storage. A guide mechanism, such as a guide rod or a guide rail, can be set between the lifting plate and the storage box to make the lifting of the lifting plate more stable and controllable, and prevent the lifting plate from tilting or getting stuck during operation.

[0050] The second implementation method:

[0051] Figure 1-Figure 8 Shown.

[0052] A first pulley 10 is provided between the top end of the column 2, the bottom end of the counterweight box 4, the bottom end of the first lifting plate 7, the bottom end of the second lifting plate 8 and the steel rope 9, and the first pulley 10 is rotatably connected to the corresponding column 2, counterweight box 4, first lifting plate 7, second lifting plate 8 and steel rope 9 respectively.

[0053] The first storage box 5 and the second storage box 6 are both rotatably connected to the second pulley 11 at one end away from the column 2 , and the outer ends of the second pulley 11 are both slidably connected to the steel rope 9 .

[0054] An adjustment plate 12 is fixedly connected to one end of the first storage box 5 and the second storage box 6 away from the column 2. A through hole is formed in the adjustment plate 12, and an adjustment screw 13 is slidably connected in the through hole.

[0055] The top end of the adjusting screw 13 is fixedly connected to the steel rope 9 , and the outer end of the adjusting screw 13 is threadedly connected to an adjusting nut 14 , and the adjusting nut 14 abuts against the bottom end of the adjusting plate 12 .

[0056] A counterweight chamber 15 is provided in the counterweight box 4, and the counterweight chamber 15 is filled with water. A water inlet pipe is fixedly connected to the top end of the counterweight box 4, and a drain pipe is fixedly connected to the bottom end of the counterweight box 4.

[0057] Both ends of the rotating shaft of the first pulley 10 are fixedly connected with brackets, and one end of the inner wall of the column 2 close to the counterweight box 4 is fixedly connected with a plurality of ribs.

[0058] The first storage box 5 and the second storage box 6 both have through grooves for accommodating the steel rope 9 at positions corresponding to the steel rope 9, and brackets are also fixedly connected to both ends of the rotating shaft of the second pulley 11.

[0059] When no steel plate is placed on the top of the first lifting plate 7 and the second lifting plate 8, the bottom end of the counterweight box 4 contacts the bottom end of the column 2. At this time, the top ends of the first lifting plate 7 and the second lifting plate 8 are flush with the top ends of the first storage box 5 and the second storage box 6.

[0060] A first pulley 10 is provided at the connection between the top of the column 2, the bottom of the counterweight box 4, the bottom of the first lifting plate 7, the bottom of the second lifting plate 8 and the steel rope 9. The first pulley 10 adopts a bearing structure and is rotatably connected to the column 2, the counterweight box 4, the first lifting plate 7 and the second lifting plate 8 through a rotating shaft. The steel rope 9 passes around the first pulley 10 and matches with the rolling groove of the pulley. The first pulley 10 can be made of stainless steel or engineering plastics, which has good wear resistance and self-lubrication.

[0061] The first storage box 5 and the second storage box 6 are both rotatably connected to the ends away from the pillar 2. The second pulley 11 also adopts a bearing structure and is rotatably connected to the storage box through a rotating shaft. The steel rope 9 passes around the second pulley 11 and matches the outer circumference of the pulley. The second pulley 11 plays the role of guiding and tensioning the steel rope 9.

[0062] An adjustment plate 12 is also fixedly connected to the end of the first storage box 5 and the second storage box 6 away from the column 2. A through hole is provided on the adjustment plate 12, and an adjustment screw 13 is slidably connected in the through hole. The top of the adjustment screw 13 is fixedly connected to the steel rope 9, and the outer side of the screw is threadedly connected to an adjustment nut 14. By rotating the adjustment nut 14, the adjustment screw 13 can be moved up and down in the through hole, thereby adjusting the tension of the steel rope 9 and the lower limit position of the lifting plate. When the adjustment nut 14 rotates upward, the adjustment screw 13 rises, the steel rope 9 is tightened, and the lower limit position of the lifting plate is raised; conversely, when the adjustment nut 14 rotates downward, the adjustment screw 13 descends, the steel rope 9 is loosened, and the lower limit position of the lifting plate is lowered.

[0063] The counterweight box 4 is provided with a counterweight chamber 15, which is filled with water, and the counterweight force is provided by the gravity of the water. A water inlet pipe is fixedly connected to the top of the counterweight box 4 for injecting water into the counterweight chamber 15; a drain pipe is fixedly connected to the bottom of the counterweight box 4 for draining the water in the counterweight chamber 15. By controlling the water inlet pipe and the drain pipe, the volume of water in the counterweight chamber 15 can be adjusted, thereby adjusting the weight of the counterweight box 4 to match the weight of the steel plate to be stored.

[0064] Both ends of the rotating shaft of the first pulley 10 are fixedly connected with brackets, which are fixedly connected to the column 2, the counterweight box 4, the first lifting plate 7 and the second lifting plate 8, and play the role of supporting and fixing the pulley. A plurality of ribs are fixedly connected to one end of the inner wall of the column 2 close to the counterweight box 4, and the ribs are evenly distributed along the axial direction of the column 2. The ribs play the role of strengthening the strength and rigidity of the column 2, and preventing the column 2 from being deformed under the action of the counterweight box 4.

[0065] A through slot for accommodating the steel rope 9 is provided at a position where the first storage box 5 and the second storage box 6 are tangent to the steel rope 9. The width and depth of the through slot are slightly larger than the diameter of the steel rope 9, so that the steel rope 9 can slide freely in the through slot without interfering with the storage box. The two ends of the rotating shaft of the second pulley 11 are also fixedly connected with brackets, which are fixedly connected to the storage box to support and fix the pulley.

[0066] When no steel plate is placed on the top of the first lifting plate 7 and the second lifting plate 8, the counterweight box 4 descends under the action of gravity until the bottom of the counterweight box 4 contacts the bottom of the column 2. At this time, under the pulling action of the steel rope 9, the first lifting plate 7 and the second lifting plate 8 rise to the highest position, and the top of the lifting plate is flush with the top of the first storage box 5 and the second storage box 6. This is the initial state of the device, which is convenient for placing steel plates.

[0067] By arranging the first pulley 10 at the top end of the column 2, the bottom end of the counterweight box 4, the bottom end of the first lifting plate 7 and the bottom end of the second lifting plate 8, the connection between the steel rope 9 and the column 2, the counterweight box 4 and the lifting plate can rotate flexibly, which greatly reduces the friction resistance between the steel rope 9 and the connecting parts, so that the steel rope 9 can more smoothly pull the counterweight box 4 and the lifting plate up and down, thereby improving the transmission efficiency of the device.

[0068] The second pulley 11 disposed at one end of the first storage box 5 and the second storage box 6 away from the column 2 can play a good guiding role. When the steel rope 9 passes around the second pulley 11, it can ensure that the steel rope 9 always maintains a proper angle with the storage box, preventing the steel rope 9 from interfering with or separating from the storage box, making the tension state of the steel rope 9 more stable, and improving the transmission effect of the steel rope 9.

[0069] By arranging the adjustment plate 12, the adjustment screw 13 and the adjustment nut 14 on the first storage box 5 and the second storage box 6, the tension of the steel rope 9 and the lower limit position of the lifting plate can be easily adjusted. When it is necessary to adapt to steel plates of different weights, the tension of the steel rope 9 and the position of the lifting plate can be quickly adjusted by rotating the adjustment nut 14, so that the device can flexibly adapt to different storage needs, thereby improving the practicality of the device.

[0070] The counterweight box 4 is provided with a counterweight chamber 15. The weight of the counterweight box 4 can be precisely controlled by filling or draining water in the counterweight chamber 15. The adjustability of the weight of the counterweight box 4 enables it to match steel plates of different weights, ensuring the stability and controllability of the steel plate storage process. At the same time, water is convenient to use as a counterweight medium, low in cost, and also convenient for the movement and transportation of the counterweight box 4.

[0071] By arranging brackets at both ends of the rotating shaft of the first pulley 10 and the second pulley 11, and reliably connecting with the column 2, the counterweight box 4, the first lifting plate 7, the second lifting plate 8 and the storage box, the stability of the pulley is improved, ensuring that the pulley will not loosen or fall off during long-term use. At the same time, ribs are arranged on the inner wall of the column 2 to further improve the strength and rigidity of the column 2, so that it can reliably support and guide the counterweight box 4, ensuring the overall structural strength of the device.

[0072] The third implementation method:

[0073] Figure 1-Figure 8 Shown.

[0074] A working method of a steel plate storage device for port wharf construction, the device is placed on a suitable horizontal ground, ensuring that the base 1 is stable and the column 2 is vertical. When starting, water is first injected into the counterweight chamber 15 in the counterweight box 4, and the amount of water injected into the counterweight chamber 15 is adjusted according to the weight of the steel plate to be stored, so that the weight of the counterweight box 4 is roughly equivalent to the weight of the steel plate. The injected water can be drawn from a water source near the wharf by a water pump and transported to the counterweight chamber 15 through a water inlet pipe.

[0075] When the counterweight chamber 15 is filled with water, under the action of gravity, the counterweight box 4 slides downward along the buffer groove 3 in the column 2 until the bottom end of the counterweight box 4 contacts the top end of the base 1. At the same time, the counterweight box 4 pulls the first lifting plate 7 and the second lifting plate 8 upward through the steel rope 9. The steel rope 9 first passes around the first pulley 10 at the bottom of the first lifting plate 7 and the second lifting plate 8, then moves upward, passes around the first pulley 10 at the top end of the column 2, and finally passes around the first pulley 10 at the bottom end of the counterweight box 4 to form a closed loop. While the steel rope 9 drives the lifting plate to rise, it also passes through the second pulley 11 on the outside of the first storage box 5 and the second storage box 6 to maintain good contact between the steel rope 9 and the storage box.

[0076] The first lifting plate 7 and the second lifting plate 8 rise until their top ends are flush with the top ends of the first storage box 5 and the second storage box 6. At this time, the lifting plate reaches the highest position, ready for the placement of the steel plate. The rising height of the lifting plate can be controlled by adjusting the length of the steel rope 9. An adjusting plate 12 is provided at the end of the first storage box 5 and the second storage box 6 away from the column 2. The adjusting plate 12 is provided with a through hole, and an adjusting screw 13 passes through the through hole. The top end of the adjusting screw 13 is connected to the steel rope 9, and the bottom end extends out of the adjusting plate 12 and is connected to the adjusting nut 14. By rotating the adjusting nut 14, the position of the adjusting screw 13 in the through hole can be adjusted, thereby adjusting the effective length of the steel rope 9.

[0077] When the steel plates need to be stored, the steel plates are placed alternately on the top of the first lifting plate 7 and the second lifting plate 8. When placing the steel plates, attention should be paid to the left and right balance, so that the gravity on the top of the first lifting plate 7 and the second lifting plate 8 is equal, to ensure that the lifting plates are balanced and the tops of the steel plates are flush. The steel plates can be hoisted into place by a crane or other lifting equipment, or they can be manually transported and stacked.

[0078] As the steel plates are continuously placed, the weight of the steel plates will be transferred to the counterweight box 4 through the lifting plate and the steel rope 9. When the weight of the steel plates exceeds the weight of the counterweight box 4, the counterweight box 4 will be pulled by the weight of the steel plates and move upward along the buffer groove 3. While the counterweight box 4 rises, the first lifting plate 7 and the second lifting plate 8 will be pulled downward by the steel rope 9, so that the steel plates are stored in the first storage box 5 and the second storage box 6. A buffer device, such as a spring or a buffer block, can be set in the storage box to reduce the impact force of the falling steel plates.

[0079] When the steel plate needs to be taken, the steel plate is taken from the first lifting plate 7 and the second lifting plate 8. As the weight of the steel plate decreases, the gravity of the counterweight box 4 exceeds the weight of the steel plate, and the counterweight box 4 will drop, while the first lifting plate 7 and the second lifting plate 8 are pulled up by the steel rope 9. The lifting plate drives the steel plate to move upward, so that the steel plate is exposed from the storage box, which is convenient for workers to take. The steel plate can be taken away by using a crane or lifting equipment, or it can be carried manually.

[0080] In actual use, the lower limit positions of the first lifting plate 7 and the second lifting plate 8 can be adjusted by adjusting the nut 14 according to the weight of the steel plate. When the effective length of the steel rope 9 is shortened, the lower limit position of the lifting plate will rise to adapt to heavier steel plates; conversely, when the effective length of the steel rope 9 is lengthened, the lower limit position of the lifting plate will fall to adapt to lighter steel plates. By adjusting the nut 14, the device can adapt to steel plates of different specifications and weights, thereby improving the applicability of the device.

[0081] The device makes full use of the principle of gravity balance, and realizes the automatic storage and use of steel plates through the interaction between the counterweight box 4 and the weight of the steel plate. When placing the steel plate, the weight of the steel plate pulls the counterweight box 4 up, drives the lifting plate down, and stores the steel plate in the storage box; when taking the steel plate, the counterweight box 4 drops, pulls the lifting plate up, and transports the steel plate to a suitable height for easy use. The whole process does not require external power, and the automatic operation of the device is realized.

[0082] Compared with traditional manual storage and lifting equipment, this device can significantly improve the efficiency of steel plate storage and retrieval. Workers only need to place the steel plates on or take them off the lifting plate, and the device can automatically complete the storage and transportation of the steel plates, eliminating the need for tedious manual handling and lifting operations, saving manpower and time costs.

[0083] The device adopts a number of safety measures to improve the reliability and safety of the device. A buffer groove 3 is set in the column 2 to make the lifting and lowering of the counterweight box 4 more stable and reduce the start-stop impact; a buffer device is set in the storage box to reduce the impact of the steel plate falling; the steel rope 9 is made of high-strength material and the force is evenly distributed through multiple pulleys, which improves the safety factor of the steel rope 9; by adjusting the nut 14, the position of the lifting plate can be accurately controlled to avoid accidents caused by excessive lifting or lowering of the lifting plate.

[0084] The device is easy to operate and easy to promote and use. The counterweight box 4 uses water as the counterweight medium. The water source is easy to obtain, and water filling and drainage are convenient, and no special counterweight material is required. By adjusting the nut 14, it can adapt to steel plates of different weights and specifications, making the application range of the device wider. The main components of the device are all universal standard parts, which are easy to manufacture and maintain, reducing the manufacturing and use costs of the device.

[0085] The device works on the principle of gravity balance, does not require additional energy input, and realizes low-carbon and environmentally friendly operation of the device. The counterweight box 4 uses water as the counterweight medium, which will not pollute the environment and can be directly discharged after use without generating waste. The device is mainly made of recyclable materials such as steel, has high recycling value, can be recycled, and conforms to the concept of energy conservation and environmental protection.

[0086] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
