Description

Technical Field

[0001] This invention belongs to the field of belt conveyor equipment, and specifically relates to an adjustable sidewall structure, a vertical shaft slag removal device, and a sidewall adjustment method. Background Technology

[0002] With the acceleration of urbanization, the depth and scale of urban underground space development and mineral resource extraction continue to expand, and the construction depth and cross-sectional dimensions of shafts are also gradually increasing, resulting in a significant increase in the amount of excavated soil during shaft excavation. The efficiency of excavated soil transportation directly determines the progress of shaft excavation. Therefore, ensuring the continuity and stability of excavated soil transportation during shaft excavation has become a key point in shaft construction.

[0003] Currently, the mainstream excavation equipment for vertical shaft excavation projects falls into two main categories: The first is the grab crane, which, during operation, delves deep into the shaft to grab excavated soil and lifts it directly to the surface for unloading. This type of equipment has a simple structure and low initial investment cost, but its lifting efficiency decreases significantly with increasing shaft depth, making it only suitable for shallow shafts, small cross-sections, and construction scenarios with relatively small amounts of excavated soil. The second category is ordinary belt conveyor equipment. Belt conveyor equipment relies on a continuously running belt to transport excavated soil. Due to its high conveying efficiency and strong continuity, it has become a common choice for transporting excavated soil in medium to deep shafts. However, during vertical shaft transport, excavated soil can spill outwards from the edges of the belt during transportation, severely affecting the efficiency of excavated soil transport.

[0004] Currently, although there are improved technologies that add corrugated sidewall structures to belt conveyors to shield the excavated soil, their effectiveness in practical applications is limited. This is because the belt speed affects the movement of the excavated soil; the faster the belt runs, the greater the kinetic energy gained by the soil, and the greater the probability and range of splashing and scattering to both sides of the belt. These corrugated sidewall structures often only adjust their own length extending into the shaft, allowing for selection of whether to shield the edges of the belt conveyor, but they struggle to meet the sidewall height requirements of the belt conveyor at different operating speeds. Therefore, there is an urgent need for an adjustable sidewall structure, a shaft excavation device, and a sidewall adjustment method that can solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing an adjustable retaining wall structure, a vertical shaft slag removal device, and a retaining wall adjustment method, aiming to solve the problem that current retaining wall structures cannot meet the varying retaining wall height requirements of the transportation device under different operating conditions. To achieve the above objective, this invention provides the following technical solution: In the first aspect, the present invention provides an adjustable edge structure: An adjustable sidewall structure includes a control system and two sidewall units. Each sidewall unit provides sidewall protection for a transport device. Each sidewall unit includes several adjustable sidewall components and several elastic connection structures. The adjustable sidewall components are arranged sequentially along their length. Each adjustable sidewall component includes a housing, a corrugated sidewall belt, and a lifting mechanism. The corrugated sidewall belt is movably fitted within the housing, with its top extending upwards beyond the housing. The lifting mechanism drives the corrugated sidewall belt to rise and fall. Every two adjacent corrugated sidewall belts are connected by elastic connection structures. The control system is electrically connected to each lifting mechanism and is used to independently or collaboratively control each lifting mechanism to achieve real-time adjustment of the vertical height of each corrugated sidewall belt.

[0006] Furthermore, the corrugated sidewall belt includes a sidewall portion and a bottom liner portion; the bottom liner portion is located below the sidewall portion and is perpendicular to the sidewall portion.

[0007] Furthermore, the lifting mechanism includes at least one lifting component; the lifting component includes a drive motor, a lifting rod, a first compression spring, and a pressure plate; the drive motor is located in the lower part of the housing; the housing has an accommodating space inside, and the output shaft of the drive motor passes through the accommodating space; the lower end of the lifting rod is drivenly connected to the output shaft of the drive motor, and the upper end is fixedly connected to the pressure plate; the pressure plate is fixedly located below the bottom liner; the first compression spring is sleeved on the outer peripheral wall of the lifting rod, and its upper end is connected to the bottom surface of the pressure plate.

[0008] Furthermore, the lifting mechanism also includes several sets of return springs; the several sets of return springs are arranged at equal intervals along the length of the corrugated sidewall belt; each set of return springs includes two second compression springs symmetrically arranged on the left and right sides of the lifting rod; the upper end of the second compression spring is connected to the bottom surface of the pressure plate, and the lower end is connected to the bottom surface of the housing.

[0009] Furthermore, each lifting mechanism has two or more lifting components; the lifting components are parallel to each other and equally spaced.

[0010] Furthermore, the elastic connection structure is a flexible leak-proof pocket; the flexible leak-proof pocket includes a flexible connecting strap and a flexible bottom pocket connected to the lower end of the flexible connecting strap; the left and right ends of the flexible connecting strap are connected to the edge portions of two adjacent corrugated edge belts; the two ends of the flexible bottom pocket are respectively connected to the bottom lining portions of two adjacent corrugated edge belts.

[0011] Furthermore, the height adjustment range of the corrugated sidewall belt is between 30mm and 45mm.

[0012] Secondly, employing the aforementioned adjustable sidewall structure, the present invention also provides a vertical shaft slag removal device: A vertical shaft slag removal device includes at least a conveying device; the conveying device includes at least a conveyor belt and two baffles symmetrically arranged on the left and right sides of the conveyor belt; two side-blocking units are symmetrically arranged on the left and right sides of the baffles, and the housing is fixed to the outer side of the corresponding baffle; in each flexible leak-proof pocket, the rear side of the flexible bottom pocket is fixedly connected to the outer wall of the baffle, and the left and right sides of the flexible bottom pocket are respectively connected to two adjacent bottom lining parts; the control system is also electrically connected to the conveyor belt and is used to adjust the side-blocking height of the corrugated side-blocking belt in real time according to the transportation situation of the conveyor belt.

[0013] Thirdly, in addition to employing the aforementioned vertical shaft slag removal device, this invention also provides a method for adjusting the retaining wall: A method for adjusting the edge guard includes the following steps: S1: Divide the conveying device into several adjustment zones along its conveying direction; wherein the range of each adjustment zone corresponds one-to-one with the range of each adjustable sidewall component. S2: Preset sampling period and collect slag transport parameters in real time during each sampling period; wherein, the slag transport parameters include at least the slag transport speed of the conveyor belt; S3: Based on the slag transportation parameters, determine the slag retaining edge range of each adjustment zone in the current sampling period; then, based on the slag retaining edge range, generate the target retaining edge height signal for the corresponding adjustment zone. S4: Output the target sidewall height signal of each adjustment zone to the control system; cause the control system to drive the lifting mechanism located in the corresponding adjustment zone to adjust the corrugated sidewall belt of that zone to the target sidewall height.

[0014] Furthermore, in step S2, the slag transport parameters also include the slag and soil accumulation morphology parameters of each adjustment zone.

[0015] The beneficial effects of this invention are: 1. This invention divides the side-blocking unit into multiple independent adjustable side-blocking components and connects them in series using an elastic connection structure. This decomposes the side-blocking structure into multiple individually adjustable parts, which can be flexibly adjusted according to the real-time operation of each position of the conveying device during operation, effectively improving the overall side-blocking effect.

[0016] 2. By setting a first compression spring and a second compression spring group, the present invention provides effective elastic support for the corrugated sidewall belt, further improving the overall rigidity and reliability of the adjustable sidewall structure and ensuring its lifting stability.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the present invention is not limited to the following embodiments.

[0025] Example 1: See attached Figure 1 .

[0026] In a first aspect, this embodiment provides an adjustable sidewall structure, including a control system and two sidewall units; the sidewall units are used to provide sidewalls for a transport device; each sidewall unit includes several adjustable sidewall components and several elastic connection structures; each adjustable sidewall component is arranged sequentially along its own length; each adjustable sidewall component includes a housing 1, a corrugated sidewall belt 2, and a lifting mechanism 3; the corrugated sidewall belt 2 is movably fitted into the housing 1, and the top of the corrugated sidewall belt 2 extends upward beyond the housing 1; the lifting mechanism 3 is used to drive the corrugated sidewall belt 2 to rise and fall; every two adjacent corrugated sidewall belts 2 are connected by an elastic connection structure; the control system is electrically connected to each lifting mechanism 3, and is used to independently or collaboratively control each lifting mechanism 3 to achieve real-time adjustment of the vertical height of each corrugated sidewall belt 2.

[0027] As can be seen from the above structure, the two side-guard units are used to clamp the transport device within them, thereby performing side-guarding operations on the transport device. Each side-guard unit consists of multiple adjustable side-guard components arranged sequentially along its own length and several elastic connection structures that flexibly connect two adjacent adjustable side-guard components, forming an integral side-guard structure extending along the length direction. Specifically, the corrugated side-guard belt 2 is installed inside the housing 1 and can be driven by the lifting mechanism 3 to adjust its height, thereby changing the side-guarding height range of the corrugated side-guard belt 2.

[0028] In practical applications, two sidewall units can be placed on the left and right sides of the conveying device to shield the left and right edges of the device. Under the control of the control system, the sidewall requirements of the conveying device under different transportation conditions can be met. When the height of two or more adjacent corrugated sidewall belts 2 changes, the elastic connection structure connected to them can be stretched or compressed accordingly. Through its own deformation, it can always fill the gaps between adjacent corrugated sidewall belts 2, so that the sidewall unit as a whole forms a continuous, seamless, and height-variable flexible sidewall belt structure.

[0029] In addition, the two side-blocking units are also controlled independently or collaboratively using a control system. The control system can employ an existing PLC controller, connected to each of the lifting mechanisms 3 of the two side-blocking units, to independently control each lifting mechanism 3. This regulates the lifting height of the corrugated side-blocking belt 2 and adjusts its height in real time according to the changing transport conditions of the target device, such as the conveyor, to adapt to the required slag-blocking height under different operating conditions. This invention, by disassembling the side-blocking structure into multiple individually adjustable parts, allows the control device to flexibly adjust the height of the corrugated side-blocking belt 2 at different positions based on the real-time operating conditions of the conveyor, effectively improving the overall side-blocking effect.

[0030] Example 2: See attached Figures 1-3 Based on Embodiment 1, the corrugated sidewall belt 2 includes a sidewall portion 21 and a bottom liner portion 22; the bottom liner portion 22 is located below the sidewall portion 21 and is perpendicular to the sidewall portion 21.

[0031] As can be seen from the above structure, the baffle portion 21 is usually made of wear-resistant and impact-resistant rubber or polymer composite material. Its cross-section is continuously corrugated, which has deformation capability and can effectively block objects splashed outward from the target device. The bottom liner portion 22 is located at the bottom of the baffle portion 21 and is vertically connected to the baffle portion 21, forming an L-shaped cross-section. The core function of the bottom liner portion 22 is to provide a stable and reliable support and force application plane for the lifting mechanism 3, ensuring that the lifting force can be applied evenly and vertically to the entire baffle belt, and avoiding skewing or jamming during the lifting process.

[0032] The lifting mechanism 3 includes at least one lifting component; the lifting component includes a drive motor 31, a lifting rod 32, a first compression spring 33, and a pressure plate 34; the drive motor 31 is located at the lower part of the housing 1; the housing 1 has an internal accommodating space, and the output shaft of the drive motor 31 passes through the accommodating space; the lower end of the lifting rod 32 is drivenly connected to the output shaft of the drive motor 31, and the upper end is fixedly connected to the pressure plate 34; the pressure plate 34 is fixedly located below the bottom liner 22; the first compression spring 33 is sleeved on the outer peripheral wall of the lifting rod 32, and its upper end is connected to the bottom surface of the pressure plate 34.

[0033] As can be seen from the above structure, the drive motor 31 serves as the power source to drive the lifting rod 32 to move linearly up and down within the accommodating space. Specifically, the drive motor 31 can be an existing linear motor. A pressure plate 34 is fixedly connected to the top of the lifting rod 32, and the pressure plate 34 is fixedly connected to the bottom liner 22. Therefore, when the drive motor 31 drives the lifting rod 32 to rise and fall, the corrugated side belt 2 will be driven to rise and fall synchronously, while the first compression spring 33 plays a buffering and protective role.

[0034] The lifting mechanism 3 also includes several sets of return springs; the sets of return springs are arranged at equal intervals along the length of the corrugated side belt 2; each set of return springs includes two second compression springs 35 symmetrically arranged on the left and right sides of the lifting rod 32; the upper end of the second compression spring 35 is connected to the bottom surface of the pressure plate 34, and the lower end is connected to the inner bottom surface of the housing 1.

[0035] As can be seen from the above structure, a return spring assembly is provided to further provide elastic support to the corrugated sidewall belt 2. The return spring assembly includes two second compression springs 35, which can indirectly support the corrugated sidewall belt 2 from the left and right sides respectively, providing a stable balancing force and ensuring stable support. Furthermore, when the corrugated sidewall belt 2 descends, the second compression springs 35 are further compressed, storing elastic potential energy. When the corrugated sidewall belt 2 rises, the lifting force of the lifting rod 32, together with the second compression springs 35, accelerates the upward speed.

[0036] Each lifting mechanism 3 has two or more lifting components; the lifting components are parallel to each other and equally spaced.

[0037] As can be seen from the above structure, such as Figure 1 As shown, each lifting mechanism 3 includes two lifting components, which are arranged parallel to each other along the length of the housing 1. The spacing between the two lifting components can be adjusted according to requirements. During operation, by synchronously driving the lifting components in the lifting mechanism 3 to lift and lower, the uniformity of the force on the corresponding corrugated sidewall belt 2 can be further ensured, so that it remains horizontal and stable during the lifting process, thereby ensuring the reliable sidewall effect.

[0038] Example 3: See attached Figures 1-3 Based on Embodiment 2, the elastic connection structure is a flexible leak-proof pocket 4; the flexible leak-proof pocket 4 includes a flexible connecting strap 41 and a flexible bottom pocket 42 connected to the lower end of the flexible connecting strap 41; the left and right ends of the flexible connecting strap 41 are connected to the edge portions 21 of two adjacent corrugated edge belts 2; the two ends of the flexible bottom pocket 42 are respectively connected to the bottom lining portions 22 of two adjacent corrugated edge belts 2.

[0039] As can be seen from the above structure, the flexible leak-proof pocket 4 includes a flexible connecting strip 41 that simultaneously connects two adjacent side guards 21 laterally and a flexible bottom pocket 42 connected to the lower end of the flexible connecting strip 41. The flexible bottom pocket 42 can fill the bottom gap between the two adjacent corrugated side guards 2, preventing items on the target device from leaking outward between the two adjacent adjustable side guards.

[0040] When the heights of two adjacent corrugated side guard belts 2 are the same, the flexible leak-proof pocket 4 is in the initial folded state. When the heights of two adjacent corrugated side guard belts 2 are not the same, the flexible leak-proof pocket 4 can undergo elastic deformation along the length or width direction as the height changes, providing elastic buffering without affecting the side guarding effect of each adjustable side guard component.

[0041] The height adjustment range of the corrugated sidewall belt 2 is between 30mm and 45mm.

[0042] As can be seen from the above structure, the upper and lower limits of the lifting of the corrugated sidewall belt 2 can be adjusted according to the actual sidewall requirements. Specifically, setting the lifting stroke between 30mm and 45mm is beneficial to ensuring the rigidity, response speed and service life of the overall structure.

[0043] Example 4: See attached Figures 1-3 Secondly, this embodiment provides a vertical shaft slag removal device, applied to the adjustable sidewall structure described in any of Embodiments 2 to 3.

[0044] The vertical shaft slag removal device includes at least a conveying device; the conveying device includes at least a conveyor belt 5 and two baffles 6 symmetrically arranged on the left and right sides of the conveyor belt 5; two side-blocking units are symmetrically arranged on the left and right sides of the baffles 6, and the housing 1 is fixed to the outside of the corresponding baffle 6; in each flexible leak-proof pocket 4, the rear side of the flexible bottom pocket 42 is fixed to the outer wall of the baffle 6, and the left and right sides of the flexible bottom pocket 42 are respectively connected to two adjacent bottom lining parts 22; the control system is also electrically connected to the conveyor belt 5 and is used to adjust the side-blocking height of the corrugated side-blocking belt 2 in real time according to the transportation situation of the conveyor belt 5.

[0045] As can be seen from the above structure, this embodiment specifically applies the aforementioned adjustable side guard structure to a vertical shaft slag transportation scenario. Using the baffles 6 on both sides of the conveyor belt 5 as the installation base, two side guard units are respectively installed on the outer edges of the baffles 6 on both sides, and several adjustable side guard components are arranged sequentially along the transportation direction. Specifically, the housing 1 of several adjustable side guard components is fixedly installed to the baffle 6 on the same side, and the gap between two adjacent adjustable side guard components is filled by a flexible bottom pocket 42. The rear side of the flexible bottom pocket 42 is fixedly connected to the corresponding part of the outer wall of the baffle 6, and the left and right sides of the flexible bottom pocket 42 are respectively connected to two adjacent bottom lining parts 22, ensuring that the gap is completely filled. Even if the corrugated side guard belt 2 of each adjustable side guard component continuously adjusts its lifting height, this gap portion can prevent slag from attempting to splash outwards, ensuring the slag-blocking effect. The control system acquires the operating status of the conveyor belt 5 via wired or wireless means, and collects key parameters such as its slag conveying speed in real time. This data serves as the basis for adjusting the sidewall height, so that the sidewall height of each corrugated sidewall belt 2 can change in real time with the change of slag conveying speed, so as to flexibly adapt to the slag blocking requirements of the conveying device and achieve dynamic adjustment.

[0046] In addition, other slag transport parameters can be added as a basis for judging the edge protection requirements. For example, multiple image detection devices are also set at intervals along the conveying direction of the conveyor belt 5. By detecting and obtaining the slag accumulation shape in each area, the actual edge protection height requirement can be judged and dynamically adjusted according to the requirements.

[0047] Example 5: See attached Figures 1-3 Thirdly, this embodiment provides a side-blocking adjustment method, applied to the vertical shaft slag removal device as described in Embodiment 4, comprising the following steps: S1: Divide the conveying device into several adjustment zones along its conveying direction; wherein the range of each adjustment zone corresponds one-to-one with the range of each adjustable sidewall component. S2: Preset sampling period and collect slag transport parameters in real time during each sampling period; among which, slag transport parameters include at least the slag transport speed of conveyor belt 5 and the slag accumulation morphology parameters of each adjustment zone; S3: Based on the slag transportation parameters, determine the slag retaining edge range of each adjustment zone in the current sampling period; then, based on the slag retaining edge range, generate the target retaining edge height signal for the corresponding adjustment zone. S4: Output the target sidewall height signal of each adjustment zone to the control system; cause the control system to drive the lifting mechanism 3 located in the corresponding adjustment zone to adjust the corrugated sidewall belt 2 of that zone to the target sidewall height.

[0048] In step S2, the slag transportation parameters also include the slag and soil accumulation morphology parameters of each adjustment zone.

[0049] As can be seen from the above, the specific implementation method for adjusting the sidewall height of the vertical shaft slag removal device can be achieved by dividing the conveying device into zones and independently collecting the slag removal parameters of each zone. Then, based on the slag removal parameters of each zone, the target sidewall height required for the current zone is generated, and finally, the height adjustment of the corrugated sidewall belt 2 is completed by the control system.

[0050] In step S1, each adjustment zone of the conveying device corresponds to the position of an adjustable retaining member, facilitating the subsequent adjustment of the real-time slag transportation status of each zone by the control system. Step S2 sets slag transportation parameters that reflect the retaining requirements of each adjustment zone of the conveying device, such as slag transportation speed and slag accumulation morphology. Specifically, these parameters can be monitored and acquired through speed sensors, image detectors, or other existing equipment. Step S3 requires determining the target retaining height for the current cycle based on the slag transportation parameters of each adjustment zone, and finally performing the adjustment in step S4.

[0051] This invention can cyclically execute steps S2 to S4 during the operation of the vertical shaft slag removal device to achieve dynamic adjustment of the sidewall height of each adjustment zone in the conveying device, so that the sidewall height matches the real-time operation of the conveying device, and ultimately maintains the optimal overall slag-blocking effect of each adjustment zone of the conveying device under different working conditions.

[0052] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
