Description

Technical Field

[0001] The present invention belongs to the technical field of ground protection, and particularly relates to a ground protection device for vehicle access channels in air-supported membranes. Background Art

[0002] The air-supported membrane yard enclosure is a new type of enclosed structure that has emerged in recent years. It is a new type of building structure form for the deepening of air-supported membrane buildings in the environmental protection enclosure of industrial yards. A closed space is made of membrane materials, anchored, and after inflation, with an appropriate steel cable system, it becomes a closed coal storage and transportation building that can resist wind, rain, and snow. In the industrial yard enclosure structure, since the air-supported membrane coal yard relies on the air pressure difference inside and outside to support the entire air-supported membrane structure, it does not require a load-bearing structure, has no flexural, torsional, and compressive members, is light in weight, has lower requirements for the foundation and base, and at the same time has the advantages of low cost, short construction period, environmental protection performance, more favorable air-supported membrane structure compared to steel structures, and can implement super-large spans. Currently, a large number of enterprises such as power plants, coking plants, steel plants, coal mines, port terminals, etc. are adopting air-supported membrane structures for enclosure.

[0003] The vehicle access channel, as a part of the air-supported membrane, is a dedicated channel for transportation vehicles, operation machinery, maintenance vehicles, etc. to enter and exit. The ramps inside the channel and outside the entrance and exit are all (reinforced) concrete floors. In air-supported membrane enclosed yards such as coal yards, ore yards, sand and gravel yards, and coking material yards, heavy crawler machinery (such as large excavators, coal pushers, crawler cranes, etc.) will enter and exit for operation. Since the machinery is all heavy equipment, when entering and exiting the vehicle access channel, it will cause irreversible damage to the ground inside the channel ramp, affecting its use. The air-supported membrane belongs to a positive pressure-supported space system. When the ground at the bottom of the channel door is damaged, the air-supported membrane will also have pressure loss, affecting the overall safety.

[0004] In practical applications, a special material rubber is installed on the side of the crawler that is stressed by means of pasting and bonding. There is a professional term called "rubberized crawler". With it, the crawler machinery can reduce the damage to the ground of the air-supported membrane vehicle access channel, and at the same time greatly reduce the noise. However, installing rubber on the crawler belt seems simple, but in fact, it has very high requirements, especially for the material of this rubber. Considering aspects such as the convenience of production use in industrial yards, the rubber replacement frequency, and economy, this method is not economically practical.

[0005] Every time a vehicle enters and exits, measures such as laying (rubber sheets, plywood, steel plates, etc.) on the ramp and the internal ground of the vehicle access channel are taken as ground protection measures. However, each time it requires the cooperation of multiple personnel for laying, tidying up, and cleaning, and sometimes it also requires the deployment of machinery for transportation to complete, which is very inconvenient. Summary of the Invention

[0006] The object of the present invention is to provide a ground protection device for vehicle access channels in air-supported membranes, which has a simple structure and a reasonable design, in order to solve the above problems.

[0007] The present invention achieves the above object through the following technical solutions:

[0008] A ground protection device for vehicle access channels in air-supported membranes, comprising a metal protection plate disposed at the ground position of the air-supported membrane vehicle access channel. A support column body is disposed below the metal protection plate, and the bottom of the metal protection plate is connected to the top of the support column body. The number of the support column bodies is several groups, and several groups of the support column bodies are divided into two columns in a column form. The length direction of the column is the access direction of the channel, and the two columns of the support column bodies support the metal protection plate.

[0009] As a further optimized scheme of the present invention, the metal protection plate is welded to the support column body, and the metal protection plate and the support column body are disposed inside the concrete.

[0010] As a further optimized scheme of the present invention, the support column body is a movable support column, and the distance between the two columns of the support column bodies is adjustable.

[0011] As a further optimized scheme of the present invention, the support column body includes a movable support base. An embedded ground groove is provided under the ground of the air-supported membrane vehicle access channel. Each of the support bases in the two columns of the support column bodies moves closer to or away from each other in the embedded ground groove. The support column body further includes a support plate member, and the support plate member contacts the bottom surface of the metal protection plate to support the metal protection plate.

[0012] In this solution, an embedded ground groove is provided, and the support column body is disposed in the embedded ground groove. The support column body is a movable support column, which includes a movable support base. The movable form includes, but is not limited to, a linear movement form constituted by any mechanical structure, and a linear movement form driven by electrical components such as a telescopic cylinder or an electric telescopic rod. In essence, the movement of the two columns of the support column bodies can be that the two columns of the whole support column bodies move closer to or away from each other. Through this method, the present embodiment can well cope with the passage of vehicles with different crawler wheelbases.

[0013] As a further optimized scheme of the present invention, the metal protection plate includes at least two support areas, and a connection area is provided between the two support areas.

[0014] In this solution, it is feasible to use the metal protection plate as a whole plate, or it can also be separated into a composition manner of two support areas and one connection area. The support column body moves horizontally (width direction) below the support area.

[0015] As a further optimized solution of the present invention, the support column body further includes a telescopic rod member, the telescopic rod member is arranged on the upper end surface of the support base, a rotating support is rotatably connected to the telescopic end of the telescopic rod member, the support plate member is connected to the rotating support, the device includes a control device, the control device controls the telescopic rod member to extend or contract, and the control device is connected to the movable support base to control the movement of the support base.

[0016] In this solution, the control device can be selected to use a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Microcontroller Unit), which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size and can be placed inside the instrument, but it has a small storage capacity, simple input and output interfaces, and low power consumption. In this embodiment, the model of the single-chip microcomputer is not required; and it should also be noted that the above-mentioned telescopic rod member can also be selected from a hydraulic telescopic rod system component, a pneumatic telescopic rod system component, an electric control telescopic rod system component, and other forms of telescopic components, without special requirements, as long as it can meet the telescopic movement.

[0017] As a further optimized solution of the present invention, the support base is further connected with a rotating device, the rotating device is connected with the telescopic rod member, the bottom of the metal protection plate is connected with a slideway, the opening of the slideway is located at the bottom, the support plate member is inserted into the slideway and slides along the slideway, the two columns of support column bodies approach or move away from each other, a rotating area is arranged in the slideway, when the support plate member moves to the rotating area, the rotating device drives the telescopic rod member to act, and the telescopic rod members in the support column bodies shorten or extend in sequence to tilt the metal protection plate.

[0018] In this solution, the rotating device can also be selected in the form of integral rotation driven by a driving motor, or other driving forms of electrical components can be selected. In this embodiment, usually, when the support base moves horizontally along the chute, the two columns of support column bodies approach or move away from each other. When it is located in the rotating area, the telescopic rod body, the rotating support and the support plate member can be driven to rotate by the rotating device. At this time, the support area of the metal protection plate is in a tiltable state, and the control device can control the telescopic rod members to extend and contract to tilt the support area of the metal protection plate, which is convenient for cleaning the channel area; and it should be emphasized that when the structure in this embodiment is in use, since the rotation of the rotating support is affected by the slideway when the support base moves horizontally and cannot rotate, the stability during support is further improved. When the rotating support is driven to rotate by the rotating device by a certain angle, its rotation can tilt the metal protection plate, and the whole structure is relatively stable.

[0019] As a further optimized solution of the present invention, an inner plate member is arranged in the embedded ground groove. Connection holes are formed on the surface of the inner plate member. The telescopic member is located in the connection holes. A cumulative groove is fixedly connected to the end of the inner plate member. The cumulative groove is located at the lower side position after the metal protection plate is inclined.

[0020] As a further optimized solution of the present invention, a movable push plate is arranged on the surface of the inner plate member. The push plate scrapes the surface of the inner plate member. The push plate includes at least two groups of first push seats and at least two groups of second push seats. The second push seats slide in the first push seats. A spring assembly is arranged between one end of the second push seat and the inner wall of the first push seat. And the sliding direction of the second push seat is perpendicular to the moving direction of the push plate. One ends of the two groups of second push seats are in contact with each other. A protective housing is fixedly connected to the outer surface of the telescopic member. The cross section of the protective housing is quadrilateral. The connecting lines of two opposite corners of the quadrilateral of the protective housing are respectively the moving direction of the push plate and the direction perpendicular to the moving direction of the push plate. The contact position of the two groups of second push seats corresponds to the connecting lines of the two opposite corners of the protective housing. The direction of the connecting lines of the two opposite corners is the moving direction of the push plate.

[0021] In this solution, when the push plate moves past the protective housing, since the second push seat can retract into the first push seat, the end face of the second push seat can cooperate with the side wall of the protective housing to move, so as to facilitate the push plate to clean the entire surface of the inner plate member.

[0022] As a further optimized solution of the present invention, a clamping column is fixedly connected to the outer surface of the telescopic member. A driving groove is formed in the inner wall of the protective housing. The clamping column is inserted into the driving groove and slides. The driving groove drives the protective housing to move up and down.

[0023] In this solution, when the rotating device drives the telescopic member and the rotating support to move, the protective housing is driven by the clamping column in cooperation with the driving groove, so that the entire protective housing moves down, so as to clean the dust on the surface of the protective housing. The actual height of the protective housing can cover the lower end face of the slideway to the upper end face of the inner plate member under normal conditions.

[0024] The beneficial effects of the present invention are as follows: By setting the metal protection plate and the supporting column body at its bottom, the supporting strength of the entire channel area is enhanced; the supporting column body can be set as a fixed type, welded to the metal protection plate and used after pouring concrete, or it can be set as a movable type, so that the supporting column body can be adjusted according to the distance between the crawler shafts of the vehicles passing through the channel as needed, thereby adjusting the distance between two rows of supporting column bodies, making the use of the device more flexible; and, by setting the rotatable rotating support and the support plate member, on the basis of providing a stable supporting force, the supporting area inside the metal protection plate can be tilted and rotated, so as to facilitate cleaning the surface of the metal protection plate after the vehicle passes; the whole device has a simple structure, is easy to operate, is flexible in use, and is convenient for protecting the ground of the air film vehicle to enter and exit the channel.

It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as a limitation on the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0039] Embodiment 1

[0040] As Figure 1 shown, a ground protection device for vehicle access channels of air film includes a metal protection plate 1 arranged at the ground position of the air film vehicle access channel. A support column 2 is arranged below the metal protection plate 1. The bottom of the metal protection plate 1 is connected to the top of the support column 2. The number of the support columns 2 is several groups. The several groups of support columns 2 are divided into two columns in the form of columns. The length direction of the column is the access direction of the channel. The two columns of support columns 2 support the metal protection plate 1.

[0041] It should be noted that the metal protection plate 1 includes but is not limited to steel plates / iron plates / alloy plates / reinforced mesh sheets, etc. In actual design, considering the economy of the protection device, the inner edge distance A between the vehicle passage ramp and the ground protection device is designed according to the minimum track center distance of the heavy crawler equipment entering and leaving the air film bin; the outer edge distance B between the vehicle passage ramp and the ground protection device is not less than the maximum track center distance of the heavy crawler equipment entering and leaving the air film bin, and is not greater than the maximum track outer edge distance of the entering and leaving equipment at most; the upper embedded plate (steel plate / iron plate / alloy plate / reinforced mesh, etc.) of this protection device can be composed of one or more pieces. The specific specifications and models of the embedded plate are designed according to the overpressure equipment parameters, and the minimum width of the embedded plate is not less than 1 / 2 of the track width of the largest equipment.

[0042] Furthermore, the metal protection plate 1 is welded to the support column 2, and the metal protection plate 1 and the support column 2 are arranged inside the concrete.

[0043] Among them, the support column 2 is selected as a threaded steel bar in this embodiment, which is the lower embedded part; the top elevation of the embedded part is not lower than the ground elevation of the vehicle passage and the ramp surface elevation, and the bottom elevation of the embedded plate shall not be higher than the ground elevation of the vehicle passage and the ramp surface elevation. The steel plate / iron plate / alloy plate / reinforcement mesh is used as the upper compression contact surface of the protection device and is welded to the embedded threaded steel bars in advance to form a ground protection device. The size of the protection device is designed according to the track wheelbase and track width of the heavy crawler machinery inside the air film. It is tied to the reinforcement mesh of the vehicle passage ground and ramp in advance, and can form an integral whole during the later concrete pouring, which is beneficial to maintaining stability when the protection device is compressed and can also improve the service life; the size and form of the lower (threaded) steel bar embedded parts are designed according to the design standards of the internal and external ramps and the ground hardening structure of the vehicle passage. There are no less than 2 embedded (threaded) steel bars at the lower part of each embedded part, and the shape, quantity, and size of the lower embedded (threaded) steel bars are determined according to the situation.

[0044] Embodiment 2

[0045] As Figures 1 to 7 shown, a ground protection device for vehicle access channels in an air film includes a metal protection plate 1 arranged at the ground position of the vehicle access channel in the air film. A support column 2 is arranged below the metal protection plate 1. The bottom of the metal protection plate 1 is connected to the top of the support column 2. The number of the support columns 2 is several groups, and several groups of the support columns 2 are divided into two columns in a column form. The length direction of the column is the access direction of the channel, and the two columns of the support columns 2 support the metal protection plate 1.

[0046] In this embodiment, the support column 2 is a movable support column, and the distance between the two columns of the support columns 2 is adjustable.

[0047] Furthermore, the support column 2 includes a movable support base 21. An embedded ground groove is arranged under the ground of the vehicle access channel in the air film. The support bases 21 of each column in the two columns of support columns 2 move closer to or away from each other in the embedded ground groove; the support column 2 further includes a support plate member 24, and the support plate member 24 contacts the bottom surface of the metal protection plate 1 to support the metal protection plate 1.

[0048] It should be noted that in this embodiment, an embedded ground groove is provided, and the support column 2 is arranged in the embedded ground groove. The support column 2 is a movable support column, which includes a movable support base 21. The movable form includes, but is not limited to, any linear movement form constituted by a mechanical structure and the linear movement form driven by electrical components such as a telescopic cylinder or an electric telescopic rod. Essentially, the movement of the two columns of support columns 2 can be that the two columns of the whole support columns 2 move closer to or away from each other. Through this method, this embodiment can well cope with the passage of vehicles with different track wheelbases.

[0049] Further, the metal protection plate 1 includes a support area 11, and there are at least two groups of the support areas 11, and a connection area 12 is arranged between the two groups of the support areas 11.

[0050] In this solution, it is feasible to use the metal protection plate 1 as a whole plate, or it can also be separated into a structure composed of two groups of support areas 11 and one group of connection areas 12. The support column 2 moves horizontally (in the width direction) below the support area 11; the connection area 12 is an area that does not provide a large supporting force, and its structure can be selected in any way.

[0051] Embodiment 3

[0052] As Figures 1 to 7 shown, a ground protection device for a vehicle access passage of an air film includes a metal protection plate 1 arranged at the ground position of the air film vehicle access passage. A support column 2 is arranged below the metal protection plate 1. The bottom of the metal protection plate 1 is connected to the top of the support column 2. The number of the support columns 2 is several groups, and several groups of the support columns 2 are divided into two columns in a column form. The length direction of the column is the access direction of the passage, and the two columns of the support columns 2 support the metal protection plate 1.

[0053] In this embodiment, the support column 2 is a movable support column, and the distance between the two columns of the support columns 2 is adjustable. And, in this embodiment, the metal protection plate 1 is preferably made of a steel mesh structure, which is beneficial to the dust and mud blocks on the surface of the crawler to fall off and prevent the inside of the air film from being polluted.

[0054] Further, the support column 2 includes a movable support base 21. There is a pre-buried ground groove under the ground of the air film vehicle access passage. The support bases 21 of each column in the two columns of the support columns 2 move closer to or away from each other in the pre-buried ground groove; the support column 2 further includes a support plate member 24, and the support plate member 24 contacts the bottom surface of the metal protection plate 1 to support the metal protection plate 1.

[0055] It should be noted that, in this embodiment, a pre-buried ground groove is provided, and the support column 2 is arranged in the pre-buried ground groove. The support column 2 is a movable support column, which includes a movable support base 21. The movable form includes, but is not limited to, a linear movement form composed of any mechanical structure, and a linear movement form driven by electrical components such as a telescopic cylinder or an electric telescopic rod. Essentially, the movement of the two columns of the support columns 2 can be that the two columns of the whole support columns 2 move closer to or away from each other. Through this method, this embodiment can well cope with the passage of vehicles with different crawler wheelbases.

[0056] Furthermore, the metal protection plate 1 includes a support area 11, and there are at least two groups of the support areas 11, and a connection area 12 is arranged between the two groups of the support areas 11.

[0057] In this solution, it is feasible to use the metal protection plate 1 as a whole plate, or it can also be separated into a structure composed of two groups of support areas 11 and one group of connection areas 12. The support column 2 moves horizontally (in the width direction) below the support area 11.

[0058] The support column 2 further includes a telescopic rod member 22. The telescopic rod member 22 is arranged on the upper end surface of the support base 21. The telescopic end of the telescopic rod member 22 is rotatably connected to a rotating support 23. The support plate member 24 is connected to the rotating support 23. This device includes a control device. The control device controls the telescopic rod member 22 to extend or contract, and the control device is connected to the movable support base 21 to control the movement of the support base 21.

[0059] In this solution, the control device can be selected to use a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Microcontroller Unit), which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a miniature computer. Compared with the general-purpose microprocessor applied in a personal computer, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size and can be placed inside the instrument, but its storage capacity is small, the input and output interfaces are simple, and the function consumption is low. In this embodiment, the model of the single-chip microcomputer is not required; and it should also be noted that the above-mentioned telescopic rod member 22 can also be selected from a hydraulic telescopic rod system component, a pneumatic telescopic rod system component, an electric control telescopic rod system component, and other forms of telescopic components, without special requirements, as long as it can meet the telescopic movement.

[0060] Furthermore, the support base 21 is also connected to a rotating device. The rotating device is connected to the telescopic rod member 22. The bottom of the metal protection plate 1 is connected to a slideway 13. The opening of the slideway 13 is located at the bottom. The support plate member 24 is inserted into the slideway 13 and slides along the slideway 13. The two columns of the support columns 2 approach or move away from each other. A rotating area 14 is arranged in the slideway 13. When the support plate member 24 moves to the rotating area 14, the rotating device drives the telescopic rod member 22 to act, and the telescopic rod members 22 in the support columns 2 shorten or extend in sequence to tilt the metal protection plate 1.

[0061] It should be noted that the rotating device can also be selected in the form of integral rotation driven by a driving motor, or other driving forms of electrical components can be selected. In this embodiment, under normal conditions, when the support base 21 moves horizontally along the chute 13, the two rows of support columns 2 approach or move away from each other. When they are located in the rotation area 14, the telescopic rod 22, the rotating support 23, and the support plate 24 can be driven to rotate by the rotating device. At this time, the support area 11 of the metal protection plate 1 is in an inclined state. By controlling the telescopic rods 22 to expand and contract by the control device, the support area 11 of the metal protection plate 1 can be inclined, which is convenient for cleaning the channel area. Moreover, it should be emphasized that when the structure in this embodiment is in use, since the rotation of the rotating support 23 is affected by the slideway 13 when the support base 21 moves horizontally and cannot rotate, the stability during support is further improved. When the rotating support 23 is driven to rotate 90° by the rotating device, its rotation can incline the metal protection plate 1, and the whole structure is relatively stable.

[0062] Furthermore, as Figures 7 to 12 shown, an inner plate member 3 is arranged in the embedded ground groove. Connecting holes 5 are formed on the surface of the inner plate member 3. The telescopic rod 22 is located in the connecting holes 5. The end of the inner plate member 3 is fixedly connected with an accumulation groove 15. The accumulation groove 15 is located at the lower side position after the metal protection plate 1 is inclined. When the metal protection plate 1 is inclined, the garbage on its surface can fall into the accumulation groove 15, which is convenient for cleaning the surface stains and dust. A corresponding cleaning device can be separately arranged for the accumulation groove 15 to facilitate the centralized treatment of dust and mud blocks.

[0063] Furthermore, a movable push plate 6 is arranged on the surface of the inner plate member 3. The push plate 6 scrapes the surface of the inner plate member 3. The push plate 6 includes at least two groups of first push seats 61 and at least two groups of second push seats 62. The second push seats 62 slide in the first push seats 61. A spring assembly is arranged between one end of the second push seat 62 and the inner wall of the first push seat 61, and the sliding direction of the second push seat 62 is perpendicular to the moving direction of the push plate 6. One ends of the two groups of second push seats 62 are in contact. A protective housing 4 is fixedly connected to the outer surface of the telescopic rod 22. The cross section of the protective housing 4 is quadrilateral. The connecting lines of the two diagonals of the quadrilateral of the protective housing 4 are respectively the moving direction of the push plate 6 and the direction perpendicular to the moving direction of the push plate 6. The contact positions of the two groups of second push seats 62 correspond to the connecting lines of the two diagonals of the protective housing 4, and the direction of the connecting lines of the two diagonals is the moving direction of the push plate 6.

[0064] It should be noted that when the push plate 6 moves past the protective housing 4, since the second push seat 62 can be retracted into the first push seat 61, the end face of the second push seat 62 can move in cooperation with the side wall of the protective housing 4, so as to facilitate the push plate 6 to clean the surface of the entire built-in plate member 3; the movable manner of the push plate 6 can be driven by a telescopic device or can be the cooperation of other moving components, and it only needs to complete linear movement without other special requirements.

[0065] Further, a clamping column 41 is fixedly connected to the outer surface of the telescopic rod member 22, a driving groove 42 is formed in the inner wall of the protective housing 4, the clamping column 41 is inserted into the driving groove 42 and slides therein, and the driving groove 42 drives the protective housing 4 to move up and down.

[0066] It should be noted that in actual use, when the rotating device drives the telescopic rod member 22 and the rotating support 23 to move, the protective housing 4 is driven by the clamping column 41 in cooperation with the driving groove 42, so that the entire protective housing 4 moves downward, thereby cleaning the dust on the surface of the protective housing 4. The actual height of the protective housing 4 can cover the lower end face of the slideway 13 to the upper end face of the built-in plate member 3 in the normal state (only one implementation manner is shown in the figure).

[0067] It should be noted that for this ground protection device for vehicle access channels of air film, in use, the present application enhances the support strength of the entire channel area by setting the metal protection plate 1 and the support column body 2 at its bottom; the support column body 2 can be set as a fixed type, welded to the metal protection plate 1 and used with concrete pouring, or can be set as a movable type, so that the support column body 2 can adjust the distance between two rows of support column bodies 2 based on the distance between the crawler axles of the vehicles passing through the channel as needed, making the use of the device more flexible; and by setting the rotatable rotating support 23 and the support plate member 24, on the basis of providing a stable support force, the support area 11 in the metal protection plate 1 can be tilted and rotated, so as to facilitate cleaning the surface of the metal protection plate 1 after the vehicle passes; the entire device has a simple structure, convenient operation, flexible use, and is convenient for the ground protection of vehicle access channels of air film.

[0068] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as a limitation on the scope of the invention patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
