Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel plate temporary road paving technology, and in particular to a starting device. Background Technology
[0002] In water conservancy projects, in order to facilitate the entry of construction machinery and equipment such as dump trucks and excavators into the construction site, steel plates are often laid on the soil with low strength to form prefabricated temporary passages to facilitate the passage of construction machinery.
[0003] Due to river dredging or cleanup of polluted sediment at the construction site, and after the construction of cofferdams and the drainage area, the soil is mostly silty, with high water content and low strength. Because silty foundations are prone to significant settlement under load, the paving steel plates easily sink into them, rendering them unusable for passage. Furthermore, the repeated compression of the steel plates into the silt makes them increasingly difficult to retrieve after construction.
[0004] Common paving steel plates used for temporary roads are 3m×1.5m×6mm in size and weigh up to 212kg. When the steel plate gets stuck in the silt, a closed space is formed between the bottom of the steel plate and the silt. Lifting the steel plate will generate negative pressure, which increases the resistance to lifting the steel plate. The current operation is basically to lift the steel plate manually or dig it out with an excavator. Manual lifting is labor-intensive and difficult to operate, while digging out the steel plate with an excavator may damage the steel plate, and may also cause difficulties in moving the excavator, or even get stuck in the silt and become trapped.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0006] The technical problem to be solved by this utility model is: how to separate the sticky parts.
[0007] This utility model solves the above-mentioned technical problems through the following technical means:
[0008] This utility model claims a starting device, including an opening and closing assembly and a driving assembly. The opening and closing assembly is located between a first component and a second component, and the first component and the second component are respectively in contact with the two sides of the opening of the opening and closing assembly. The driving assembly is configured to drive the opening of the opening and closing assembly to produce an opening or closing action.
[0009] Preferably, the opening and closing assembly includes at least two plates and a pivot unit, wherein the at least two plates are connected at their ends by the pivot unit, and the pivot forms an angle to constitute the opening of the opening and closing assembly.
[0010] Preferably, the rotating shaft unit includes a bushing and a core, with at least two plates having their wide edges rolled up to form a rolled edge, the rolled edge having an annular structure, a bushing being disposed inside the rolled edge, the axis of the bushing being parallel to the wide edge, and a core being coaxially disposed inside the bushing.
[0011] Preferably, a limiting unit is provided on the plate at the edge of the first component or the second component, and the limiting unit abuts against the edge of the first component or the second component to limit the horizontal degree of freedom of the first component or the second component.
[0012] Preferably, the drive assembly includes a filling bag, a pipe, and a power source. The filling bag is arranged at the opening of the opening and closing assembly. The air port of the filling bag is connected to one end of the pipe, and the other end of the pipe is connected to the power source.
[0013] Preferably, the limiting unit includes a positioning plate, which is detachably connected to the plate surface on the side away from the shaft core.
[0014] Preferably, the positioning plate has an L-shaped cross-section, with the plate surface away from the shaft core passing through the first through hole, the horizontal plate of the positioning plate passing through the corresponding second through hole, the bolt passing through the first and second through holes, the bolt being connected to the nut, and the vertical plate of the positioning plate engaging with the edge of the first or second component.
[0015] Preferably, at least two plates are staggered and arranged above and below the filling bag.
[0016] Preferably, a rubber skeleton is provided inside the filling bag.
[0017] Preferably, the power source is an air compressor.
[0018] The advantages of this utility model are:
[0019] 1. By setting up a driving component, the opening and closing component can be driven to produce an opening or closing action. That is to say, when the opening and closing component has at least two states, in the first state, when closed, the opening and closing component is relatively thin, making it easy to place inside the two bonded parts; in the second state, the opening and closing component switches to the open state, and then the first and second parts respectively contact and engage with the two sides of the opening of the opening and closing component, which can quickly separate the two bonded or tightly attached parts.
[0020] Second, furthermore, the opening and closing assembly uses at least two plates connected at the ends by a pivot unit. First, the end connection ensures less positional interference between the two plates during the closing process. Second, for the same opening angle, the lever arm of the plate rotation is longer, thus the opening range is larger, which means that the distance between the first and second components is greater.
[0021] Third, the design of forming a rolled edge by rolling up the wide edges of the two plates in one piece not only ensures the thinness of the plates but also increases the support strength. A bushing is set inside the rolled edge, and a shaft core is set coaxially inside the bushing. It can be imagined that when the opening and closing components are closed, at least two plates are laid flat to form a flat plate, which ensures the thinness when closed and also prevents them from interfering with each other when opening.
[0022] IV. The drive component is preferably a filling bag. An air source inflates or deflates the filling bag through a pipe, driving the opening and closing component to open or close. This design has two advantages over other drive components on the market: First, after deflation, the filling bag contracts and sinks into the closed opening and closing component, maximizing the thinness of the component when closed, making it ideal for separating two tightly fitted parts. Second, the frequency and extent of inflation and deflation of the filling bag are controllable, and even when inflated, it provides excellent support for the supported component, preventing damage or tipping and impact caused by rapid opening or closing.
[0023] V. In reality, it is impossible to ensure that the opening and closing degree of each opening and closing component is uniform in actual operation. This means that when the first or second component is separated, it will slip due to gravity. Therefore, a limiting unit is provided on the plate at the edge of the first or second component. The limiting unit abuts against the edge of the first or second component to restrict the horizontal degree of freedom of the first or second component. In actual work, the slippage along the length of the first or second component is more obvious. Therefore, in combination with the actual situation, the limiting unit is more often arranged symmetrically, abutting against the two short sides of the first or second component to achieve a clamping effect and restrict the slippage of the first or second component along the length.
[0024] VI. Furthermore, the limiting unit is detachably connected to the plate surface. First, this ensures that local damage can be repaired. Second, when the first or second component is an irregularly shaped part, the angle can be adjusted according to the actual shape, so that the positioning plate fits the surface of the first or second component better.
[0025] 7. Furthermore, at least two plates are staggered above and below the filling bag, so that the force is more evenly distributed and the separation stability is higher during the opening or closing process. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] Example 1
[0035] See Figure 1 This embodiment claims protection for a starting device for separating a first component and a second component. The first component is generally a rigid sheet material, and the second component is mostly an adhesive soft layer. The sheet material is usually embedded in the adhesive soft layer, and the first component is located above the second component. The device includes an opening and closing assembly 1 and a driving assembly 2. The opening and closing assembly 1 is located between the first component and the second component, and the first component and the second component are respectively in contact with each other on both sides of the opening of the opening and closing assembly 1. The driving assembly 2 is configured to drive the opening of the opening and closing assembly 1 to produce an opening or closing action.
[0036] See Figures 1 to 3Furthermore, the opening and closing assembly 1 includes at least two plates 10 and a pivot unit 11. The pivot unit 11 includes a bushing 110 and a core 111. The wide edges of the at least two plates 10 are rolled up to form a rolled edge, which has a ring-shaped structure. The bushing 110 is disposed inside the rolled edge, and the axis of the bushing 110 is parallel to the wide edge. The core 111 is coaxially disposed inside the bushing 110. The at least two plates 10 are connected at their ends by the pivot unit 11, and the connection forms an angle to form the opening of the opening and closing assembly 1. The rolled edge is formed by rolling up the wide edges of the two plates 10. The one-piece design not only ensures the thinness of the plates 10 but also increases the support strength. The bushing 110 is disposed inside the rolled edge, and the core 111 is coaxially disposed inside the bushing 110. It is conceivable that when the opening and closing assembly 1 is closed, the at least two plates 10 are laid flat to form a plate, which ensures the thinness when closed and also prevents mutual interference when they are opened.
[0037] It is worth noting that the shaft core 111 needs to be strong enough to withstand the rotation and load of at least two plates 10 during use; in addition, the bushing 110 reduces the friction between the shaft core 111 and at least two plates 10, while keeping the shaft core in a stable position and preventing the at least two plates 10 from loosening due to vibration or wear during use.
[0038] The opening and closing assembly 1 uses at least two plates 10 connected at the ends by a pivot unit 11. First, the end connection ensures that there is less positional interference between the two plates 10 during the closing process. Second, at the same opening angle, the lever arm of the plate 10 is longer, so the opening range is larger, which means that the distance between the first component and the second component is greater.
[0039] Furthermore, the drive assembly 2 includes a filling bag 20, a pipe 21, and a power source 22. The filling bag 20 is arranged at the opening of the opening and closing assembly 1, and at least two plates 10 are staggered above and below the filling bag 20. In this way, the force is more evenly distributed and the separation stability is higher during the opening or closing process. A rubber skeleton is set inside the filling bag 20. The air port of the filling bag 20 is connected to one end of the pipe 21, and the other end of the pipe 21 is connected to the power source 22. The pipe 21 is preferably a ventilation hose, and the power source 22 is preferably an air compressor with a large flow rate and... It can operate continuously and stably supply air to multiple filling bags 20. The drive component 2 is preferably a filling bag 20. Air is inflated or deflated into the filling bag 20 via a power source 22 and a pipe 21, driving the opening and closing component 1 to open or close. This design has two advantages over other drive components on the market: First, after deflation, the filling bag 20 contracts and sinks into the closed opening and closing component 1, maximizing the thinness of the component 1 when closed, making it ideal for separating two tightly fitted parts. Second, the frequency and degree of inflation and deflation of the filling bag 20 are controllable, and even when inflated, it provides excellent support for the supported parts, preventing damage or tipping and impact caused by rapid opening or closing.
[0040] It is worth noting that the filling bag 20 is preferably an inflatable rubber bag, and the main rubber material is neoprene rubber, which has high strength, wear resistance and aging resistance. The rubber skeleton is preferably steel wire cord as the load-bearing skeleton to improve its load-bearing capacity, so that the filling bag 20 is in a deflated state before inflation and after air is absorbed, the filling bag 20 is stacked crosswise between at least two plates 10.
[0041] By setting the driving component 2, the opening and closing component 1 can be driven to open or close. That is, when the opening and closing component 1 has at least two states, in the first state, when it is closed, the opening and closing component 1 is relatively thin, which makes it easy to place inside the two bonded parts; in the second state, the opening and closing component 1 switches to the open state, and then the first and second components contact and cooperate with the two sides of the opening of the opening and closing component 1 respectively, which can quickly separate the two bonded or tightly attached parts.
[0042] Example 2
[0043] See Figures 1 to 4 Based on Embodiment 1, this embodiment has a limiting unit 12 protruding from the plate 10 located at the edge of the first component or the second component. The limiting unit 12 abuts against the edge of the first component or the second component to restrict the horizontal degree of freedom of the first component or the second component.
[0044] Furthermore, the limiting unit 12 includes a positioning plate 120, which is detachably connected to the plate surface of the plate 10 on the side away from the shaft core 111. The positioning plate 120 has an L-shaped cross-section, with the plate surface on the side away from the shaft core 111 passing through a first through hole. The horizontal plate of the positioning plate 120 passes through a corresponding second through hole. A bolt 121 passes through the first and second through holes and is connected to a nut 122. The vertical plate of the positioning plate 120 abuts against the edge of the first or second component.
[0045] The limiting unit 12 is detachably connected to the plate surface of the plate body 10. First, it ensures that local damage can be repaired; second, when the first or second part is an irregularly shaped part, the angle can be adjusted according to the actual shape so that the positioning plate 120 fits more closely to the surface of the first or second part.
[0046] In fact, it is impossible to ensure that the opening and closing degree of each opening and closing component 1 is uniform in actual operation. This means that when the first or second component is separated, it will slip due to gravity. Therefore, a limiting unit 12 is provided on the plate 10 at the edge of the first or second component. The limiting unit 12 abuts against the edge of the first or second component to limit the horizontal degree of freedom of the first or second component. In actual operation, the slippage along the length of the first or second component is more obvious. Therefore, in combination with the actual situation, the limiting unit 12 is more symmetrically arranged and abuts against the two short sides of the first or second component to achieve a clamping effect and limit the slippage of the first or second component along the length.
[0047] Example 3
[0048] This embodiment provides a practical working application scenario based on Embodiment 1 and Embodiment 2. Specifically, it involves lifting a paving steel plate that is stuck in silt using a starting device. In this case, the first component is the steel plate and the second component is the silt. In actual operation, the following steps are performed.
[0049] The starting device placement steps are as follows: When the starting device is in the closed state, insert the long side of the starting device under the steel plate. It can be fully inserted or partially inserted, depending on the specific situation of being embedded in the silt. In order to ensure that the steel plate is subjected to uniform force, it is generally arranged symmetrically along the length of the steel plate, preferably at the four corners of the steel plate. When placing it, pay attention to ensuring that the limiting unit 12 is tightly pressed against the wide edge of the steel plate. Then, considering the actual weight of the steel plate and the tightness of the steel plate embedded in the silt, add the starting device in the middle position of the steel plate.
[0050] In the step of lifting the steel plate, the power source 22, which is the air compressor, is driven to inflate the gas. The gas is then fed into the filling bag 20 through the pipe 21, causing the filling bag 20 to bulge. The starting device is then switched to the open state, which lifts the steel plate out of the silt and removes the steel plate.
[0051] See Figure 5 The starting device recovery step drives the air compressor to draw in air, the filling bag 20 retracts, and the starting device resets to the closed state.
[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
