Abstract
Description
Technical Field
[0001] This application relates to the technical field of lifting equipment, and in particular to an ultra-high speed low vacuum tube beam handling device. Background Technology
[0002] Ultra-high speed low vacuum tube beams are an important component of ultra-high speed low vacuum pipelines. Ultra-high speed low vacuum tube beams are made of concrete. After casting, gantry cranes are usually used as handling equipment to move the ultra-high speed low vacuum tube beams to other areas for storage so that the casting station can continue casting the next ultra-high speed low vacuum tube beam.
[0003] Because of the large weight of the ultra-high speed low vacuum tube beam, lifting the ultra-high speed low vacuum tube beam by the gantry crane increases the overall weight of the gantry crane, thereby increasing the kinetic energy of the gantry crane when it moves. Although the traveling wheels of the gantry crane are equipped with brakes that can stop the traveling wheels, in windy weather, it is difficult to stop the gantry crane with large kinetic energy by relying solely on the brakes. Therefore, it is necessary to add a windproof braking device to the gantry crane. For example, Chinese Patent No. CN218665054U discloses an automatic windproof rail clamping device for gantry cranes, which can drive the clamping block to clamp onto the rail through an electric hydraulic push rod to enhance the braking capability of the gantry crane.
[0004] In the above scheme, although the braking capacity of the gantry crane is enhanced, the clamping blocks will directly clamp onto the rail. When the wind is strong, the sudden braking caused by the rail clamping force can easily cause the gantry crane with high kinetic energy to collapse. Summary of the Invention
[0005] In order to enhance the braking capability of the gantry crane without increasing the risk of collapse, this application provides an ultra-high speed low vacuum tube beam handling device.
[0006] This application provides an ultra-high-speed, low-vacuum tube beam handling device, which adopts the following technical solution:
[0007] An ultra-high-speed, low-vacuum tube beam handling device includes:
[0008] Gantry crane main body;
[0009] The traveling wheels are connected to the main body of the gantry crane and are used to move on the track. The traveling wheels are equipped with brakes to stop the traveling wheels.
[0010] The brake plate is slidably mounted on the main body of the gantry crane. Two symmetrical force-enhancing grooves are provided on the brake plate. The two force-enhancing grooves are arranged along the length of the track and are inclined relative to the track.
[0011] The braking mechanism has the same number as the force-increasing slide grooves, and corresponds one-to-one with the force-increasing slide grooves. The braking mechanism includes a friction component and a resistance component.
[0012] The friction assembly includes a brake slider and a brake block. The brake slider is slidably disposed in the force-increasing groove, and the starting position of the brake slider is located at the end of the force-increasing groove away from the track. The brake slider is connected to the brake block, and the brake block is used to elastically press against the track.
[0013] Multiple sets of resistance components are provided along the extension direction of the force-enhancing slide. The resistance components are set in the braking groove opened on the bottom of the force-enhancing slide. The resistance components include a resistance plate and a resistance part. The middle part of the resistance plate is rotatably connected to the groove wall of the braking groove. One end of the resistance plate extends into the force-enhancing slide. The resistance part is located on the side of the resistance plate near the end of the force-enhancing slide away from the track. The resistance part is set in the resistance groove opened on the groove wall of the braking groove. The resistance part is used to apply a blocking force to the resistance plate. From the end of the force-enhancing slide away from the track to the end of the force-enhancing slide near the track, the blocking force that can be applied by multiple resistance parts increases progressively.
[0014] The linkage mechanism is connected to the brake and the brake plate respectively. The linkage mechanism is used to drive the brake plate to slide towards the track when the brake stops the traveling wheel, so that the brake block abuts against the track.
[0015] Optionally, the resistance part includes a resistance block and a resistance spring. The resistance block is slidably disposed in the resistance groove, and the resistance spring is connected between the resistance block and the bottom of the resistance groove. The resistance spring is used to apply a blocking force to the resistance plate when the resistance plate pushes the resistance block. From the end of the force-increasing slide away from the track to the end of the force-increasing slide close to the track, the elastic coefficients of the multiple resistance springs increase one by one.
[0016] Optionally, the brake slider is connected to a brake box, and an elastic block is provided inside the brake box. The brake block slides through the brake box, and both sides of the elastic block are connected to the brake box and the brake block, respectively. The elastic block is used to drive the brake block to elastically press against the track.
[0017] Optionally, the brake plate has two pressure relief grooves, which correspond one-to-one with the pressure amplification grooves and are located at the end of the pressure amplification groove closest to the track. The pressure relief grooves are connected to the pressure amplification grooves and are inclined relative to the track. The end of the pressure relief groove closest to the pressure amplification groove is the part of the pressure relief groove closest to the track. The vertical distance between the end of the pressure relief groove furthest from the pressure amplification groove and the track is less than the vertical distance between the end of the pressure amplification groove furthest from the pressure relief groove and the track.
[0018] Optionally, a connecting rod is connected between the brake slider and the brake box, a stabilizing support rod is connected to the connecting rod, and a stabilizing slider is connected to the stabilizing support rod. The stabilizing slider is slidably disposed in a stabilizing groove opened on the brake plate.
[0019] Optionally, counterweight baffles are connected to both sides of the end of the resistance plate that extends into the force-enhancing chute.
[0020] Optionally, the linkage mechanism includes a first link, a connecting seat, and a second link. One end of the first link is hinged to the brake plate, and the other end is hinged to the connecting seat. The connecting seat is hinged to one end of the second link, and the other end of the second link is hinged to the brake link of the brake. When the brake link of the brake stops the traveling wheel, the brake link of the brake can drive the brake plate to slide towards the track via the second link and the first link.
[0021] Optionally, the braking mechanism further includes a reset assembly, which includes a reset rack, a reset gear, and a reset coil spring. The reset rack is disposed within the force-increasing groove and the force-reducing groove, and is arranged along the extending direction of the force-increasing groove and the force-reducing groove. The reset gear is rotatably connected to the brake slider and meshes with the reset rack. The reset coil spring is disposed between the reset gear and the brake slider, and is used to drive the reset gear to rotate so that the brake slider can automatically return to the starting position.
[0022] Optionally, when the two brake plates are slid to their furthest positions, a gap is left between the brake block and the track when the brake slider slides to the position closest to the track in the force-enhancing groove.
[0023] Optionally, a wear-resistant liner may be detachably connected to the side of the brake block away from the elastic block.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] This application discloses an ultra-high-speed, low-vacuum tube beam handling device, comprising a gantry crane body, traveling wheels, brake plates, a braking mechanism, and a linkage mechanism. The brakes mounted on the traveling wheels drive the brake plates to slide when the traveling wheels are braked, allowing the wear-resistant lining plates on the brake blocks to abut against the track. Under the frictional force between the track and the wear-resistant lining plates, the brake slider slides along the force-increasing groove. On one hand, the brake slider drives the brake blocks to increase the frictional force between the wear-resistant lining plates and the track; on the other hand, the brake slider collidees with multiple resistance plates. Resistance springs apply a blocking force to the brake slider through the resistance blocks and resistance plates. The blocking force applied by the multiple resistance plates to the brake slider increases progressively. Under the action of multiple blocking forces, the brake slider can apply multiple intermittent braking forces to the gantry crane body, with the first intermittent braking force being the smallest. This makes the gantry crane body less susceptible to rapid braking force at the initial braking stage, and as the intermittent braking force gradually increases, the gantry crane body can easily and quickly stop. This enhances the braking capacity of the gantry crane body while reducing the risk of collapse. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0035] This application discloses an ultra-high-speed, low-vacuum tubular beam handling device. (Refer to...) Figure 1 A high-speed, low-vacuum tube beam handling device includes a gantry crane body 1, traveling wheels 2, brake plates 3, braking mechanism 4, and linkage mechanism 7.
[0036] The main body of the gantry crane 1 is used to lift ultra-high speed low vacuum tube beams.
[0037] Reference Figure 1 and Figure 2The traveling wheels 2 are connected to the gantry crane body 1 and are used to move on the tracks. In this embodiment, there are two sets of traveling wheels 2 and two tracks. The two sets of traveling wheels 2 are rolled on the two tracks in a one-to-one correspondence. Each set of traveling wheels 2 has two wheels. The traveling wheels 2 are rotatably connected to the gantry crane body 1. A brake 21 is provided on the traveling wheels 2 to stop the traveling wheels 2.
[0038] Reference Figure 2 and Figure 3 The brake plate 3 is slidably mounted on the gantry crane body 1. Two symmetrical force-enhancing grooves 31 are formed on the bottom surface of the brake plate 3. These two grooves 31 are arranged along the length of the track and are inclined relative to the track. In this embodiment, two sets of brake plates 3 are provided, each corresponding to one set of traveling wheels 2. Each set of brake plates 3 has two plates, located between the two traveling wheels 2. The two brake plates 3 are symmetrically arranged relative to the track, and the force-enhancing grooves 31 on the two brake plates 3 are also symmetrically arranged relative to the track. The sliding direction of the two brake plates 3 is either towards each other or away from each other.
[0039] Reference Figure 4 The number of braking mechanisms 4 is the same as the number of force-increasing grooves 31, and they correspond one-to-one. The braking mechanism 4 includes a friction component 5 and a resistance component 6.
[0040] Reference Figure 4 and Figure 5 The friction assembly 5 includes a brake slider 51 and a brake block 52. The brake slider 51 is slidably disposed in the force-increasing groove 31, and the starting position of the brake slider 51 is located at the end of the force-increasing groove 31 away from the track. The brake slider 51 is connected to the brake block 52, which is used to elastically press against the track. When the brake slider 51 slides close to the track, the brake slider 51 can gradually increase the positive pressure applied by the brake block 52 to the track.
[0041] Reference Figure 4 Multiple sets of resistance components 6 are provided along the extension direction of the force-enhancing slide groove 31. The resistance components 6 are located in the braking groove 32 opened on the bottom of the force-enhancing slide groove 31. The resistance components 6 include a resistance plate 61 and a resistance part 62.
[0042] Reference Figure 6 The middle part of the resistance plate 61 is rotatably connected to the groove wall of the brake groove 32. One end of the resistance plate 61 extends into the force-enhancing slide groove 31. The resistance plate 61 can be completely located in the brake groove 32 by rotation. The resistance plate 61 can be kept vertically in normal conditions.
[0043] Reference Figure 5 and Figure 6The resistance section 62 is located on the side of the resistance plate 61 near the end of the force-enhancing slide 31 away from the track. The resistance section 62 is set in the resistance groove 33 opened on the groove wall of the brake groove 32. The resistance section 62 is used to apply a blocking force to the resistance plate 61. The blocking force applied by the resistance section 62 can be transmitted to the brake slider 51 through the resistance plate 61 to form a braking force on the gantry crane body 1. From the end of the force-enhancing slide 31 away from the track to the end of the force-enhancing slide 31 near the track, the blocking force that can be applied by multiple resistance sections 62 increases one by one.
[0044] Reference Figure 2 and Figure 5 The linkage mechanism 7 is connected to the brake 21 and the brake plate 3 respectively. The linkage mechanism 7 is used to drive the brake plate 3 to slide towards the track when the brake 21 stops the traveling wheel 2, so that the brake block 52 abuts against the track. In this embodiment, there are four linkage mechanisms 7, which correspond one-to-one with the four brakes 21. Each linkage mechanism 7 is connected to the corresponding brake 21 and the two brake plates 3 close to the corresponding brake 21. The two brakes 21 in the same group can jointly drive the two corresponding brake plates 3 to slide.
[0045] In use, when it is necessary to brake the traveling wheel 2, the brake 21 is activated to stop the traveling wheel 2. The brake 21 can drive the two brake plates 3 to slide towards the rail through the linkage mechanism 7, so that the brake block 52 can elastically abut against the rail. After the brake block 52 abuts against the rail, the rail applies friction to the brake block 52, making it difficult for the brake block 52 to move relative to the rail. At this time, the gantry crane body 1 with high kinetic energy is difficult to stop on the rail under the wind. The gantry crane body 1 can carry the stopped traveling wheel 2 and the brake plate 3 to slide on the rail. Since the brake block 52 is difficult to move relative to the rail, the brake slider 51 can tilt and slide towards the rail in the force-increasing groove 31. During the sliding process of the brake slider 51, the normal pressure of the brake block 52 on the rail continuously increases, which also continuously increases the friction between the brake block 52 and the rail, making it increasingly difficult for the brake block 52 to slide relative to the rail.
[0046] When the brake slider 51 slides, it will collide with the resistance plate 61 one by one. During the process of the brake slider 51 colliding with the resistance plate 61, the resistance part 62 can transmit the blocking force to the brake slider 51 through the resistance plate 61. The blocking force applied to the brake slider 51 can form a braking force on the gantry crane body 1. Since the blocking force is a short-term collision force, the blocking force can apply a point braking force to the gantry crane body 1.
[0047] As the resistance force of the resistance section 62 increases gradually, the resistance force that the brake slider 51 initially experiences when it collides with the resistance plate 61 is the smallest. This allows the braking force applied by the brake slider 51 to the gantry crane body 1 to increase gradually. As a result, the gantry crane body 1 is less likely to be subjected to a large braking force when it has a large initial kinetic energy. This makes it less likely that the gantry crane body 1 will collapse due to the rapid braking force in the initial braking stage.
[0048] As the resistance force received by the brake slider 51 increases, the kinetic energy of the gantry crane body 1 gradually decreases. The subsequent larger resistance force received by the brake slider 51 can quickly brake the gantry crane body 1, thereby reducing the braking distance of the gantry crane body 1.
[0049] As the resistance force received by the brake slider 51 gradually increases, the friction between the brake block 52 and the track also gradually increases. Thus, when the brake slider 51 receives a large resistance force, the friction between the brake block 52 and the track can keep the brake slider 51 stationary relative to the track, allowing the brake slider 51 to stably apply intermittent braking force to the gantry crane body 1.
[0050] Based on the above analysis, when the brake 21 stops the traveling wheel 2, the brake slider 51 can slide tilted towards the track in the force-enhancing groove 31. Under the blocking force applied by the resistance plate 61 and the resistance part 62, the brake slider 51 can apply intermittent braking force to the gantry crane body 1 multiple times, and the intermittent braking force can increase gradually. This allows the braking force on the gantry crane body 1 to gradually increase in the form of intermittent braking, thereby enhancing the braking ability of the gantry crane body 1 on the one hand, and making it less likely to increase the risk of the gantry crane body 1 collapsing on the other hand.
[0051] Specifically, refer to Figure 6 The resistance section 62 includes a resistance block 621 and a resistance spring 622.
[0052] Reference Figure 5 and Figure 6 The resistance block 621 is slidably disposed in the resistance groove 33, and the resistance spring 622 is fixed between the resistance block 621 and the bottom of the resistance groove 33. The resistance spring 622 is used to apply a blocking force to the resistance plate 61 when the resistance plate 61 pushes the resistance block 621. From the end of the force-increasing groove 31 away from the track to the end of the force-increasing groove 31 close to the track, the elastic coefficients of the multiple resistance springs 622 increase one by one, so that the further the brake slider 51 is from the starting position, the greater the collision reaction force it receives when colliding with the resistance plate 61.
[0053] When the resistance plate 61 rotates under the push of the brake slider 51, the end of the resistance plate 61 can drive the resistance block 621 to slide into the resistance groove 33, and cause the resistance spring 622 to accumulate elastic force. The elastic force accumulated by the resistance spring 622 can form a blocking force on the brake slider 51 through the resistance block 621 and the resistance plate 61. Since the elastic force of the resistance spring 622 can gradually increase with the sliding stroke of the brake slider 51, the brake slider 51 and the resistance plate 61 are not easily damaged when they first collide. By setting the elastic coefficient of the resistance spring 622 to increase one by one, the blocking force transmitted by the resistance plate 61 can be increased one by one.
[0054] Reference Figure 6 In order to keep the resistance plate 61 vertical under normal conditions, counterweight baffles 611 are fixedly connected to both sides of the end of the resistance plate 61 that extends into the force-enhancing groove 31.
[0055] Under the gravity of the counterweight baffle 611, the resistance plate 61 can remain vertical without external force, so as to ensure that the resistance plate 61 can stably block the brake slider 51; the counterweight baffle 611 enhances the mechanical strength of the collision part of the resistance plate 61, making the resistance plate 61 less likely to be damaged by collision.
[0056] Reference Figure 5 In order to enable the brake block 52 to be elastically pressed onto the track, the brake slider 51 is connected to the brake box 53. The brake box 53 is provided with an elastic block 54. The brake block 52 slides through the brake box 53. The two sides of the elastic block 54 are fixedly connected to the brake box 53 and the brake block 52 respectively. The elastic block 54 is used to drive the brake block 52 to elastically press onto the track.
[0057] When the brake slider 51 tilts and slides toward the track, the brake slider 51 can drive the brake box 53 to move, so that the brake box 53 moves toward the track. Since the brake block 52 has already abutted against the track, the brake box 53 can compress the elastic block 54 to increase the elastic force applied by the elastic block 54 to the brake block 52, thereby increasing the normal pressure between the brake block 52 and the track.
[0058] Reference Figure 5 In order to extend the service life of the brake block 52, a wear-resistant liner 521 is detachably connected to the side of the brake block 52 away from the elastic block 54. In this embodiment, the wear-resistant liner 521 and the brake block 52 are detachably connected by countersunk bolts. By setting the wear-resistant liner 521 which can be easily replaced, the brake block 52 is less prone to wear, thereby extending the service life of the brake block 52.
[0059] Reference Figure 5In order to improve the ability of the brake block 52 to withstand the reaction force of the track, a connecting rod 55 is fixedly connected between the brake slider 51 and the brake box 53. A stabilizing support rod 56 is fixedly connected to the connecting rod 55. The stabilizing support rod 56 is inclined relative to the connecting rod 55. A stabilizing slider 57 is fixedly connected to the stabilizing support rod 56. The stabilizing slider 57 is slidably disposed in the stabilizing groove 34 opened on the brake plate 3. The stabilizing slider 57 can slide synchronously with the brake slider 51.
[0060] As the brake block 52 continuously increases the positive pressure on the track, the stabilizing support rod 56, with the stabilizing slider 57 as the support point, can apply a supporting force to the brake block 52, thereby improving the ability of the brake block 52 to withstand the track reaction force. When the stabilizing slider 57 and the brake slider 51 slide synchronously, the brake block 52 is not easy to rotate, so that the brake block 52 can stably abut against the track.
[0061] Reference Figure 4 and Figure 5 When the brake slider 51 slides to the end of the force-enhancing groove 31 closest to the track, and the gantry crane body 1 has not yet stopped, the brake block 52 will slide relative to the track with the brake plate 3. Since the positive pressure applied by the brake block 52 to the track is at its maximum at this time, the whole formed by the brake block 52 and the brake slider 51 is easily damaged.
[0062] Reference Figure 3 and Figure 5 To ensure that the brake block 52 is not easily damaged in the above-described state and can still apply braking force, the brake plate 3 has two pressure relief grooves 35. The pressure relief grooves 35 correspond one-to-one with the force amplification grooves 31, and are located at the end of the force amplification groove 31 closest to the track. The pressure relief grooves 35 and force amplification grooves 31 are connected, allowing the brake slider 51 to slide from the force amplification groove 31 into the pressure relief groove 35, and vice versa. The pressure relief grooves 35 are inclined relative to the track. The end of the pressure relief groove 35 closest to the force amplification groove 31 is the part of the pressure relief groove 35 closest to the track, and the vertical distance between the end of the pressure relief groove 35 furthest from the force amplification groove 31 and the track is less than the vertical distance between the end of the force amplification groove 31 furthest from the pressure relief groove 35 and the track.
[0063] When the brake slider 51 slides from the force-increasing groove 31 into the force-relieving groove 35, the brake slider 51 will tilt and slide away from the track, so that the normal pressure of the brake block 52 on the track can be reduced, thereby reducing the friction between the brake block 52 and the track. When the brake slider 51 slides to the end of the force-increasing groove 31 closest to the track, and the gantry crane body 1 has not yet stopped, the brake block 52 can slide relative to the track after the friction is reduced. On the one hand, the brake block 52 can continue to apply braking force to the gantry crane body 1 with sliding friction. On the other hand, after the friction between the brake block 52 and the track is reduced, the brake block 52 is not easily damaged.
[0064] Specifically, refer to Figure 2 The linkage mechanism 7 includes a first link 71, a connecting seat 72, and a second link 73. There are two first links 71, which correspond one-to-one with the brake plates 3. One end of the first link 71 is hinged to the brake plate 3, and the other ends of the two first links 71 are hinged to the connecting seat 72. The connecting seat 72 is slidably mounted on the gantry crane body 1. The connecting seat 72 is hinged to one end of the second link 73, and the other end of the second link 73 is hinged to the brake link of the brake 21. When the brake link of the brake 21 stops the traveling wheel 2, the brake link of the brake 21 can drive the two brake plates 3 to slide towards the track via the second link 73 and the first link 71.
[0065] When the brake linkage of brake 21 pulls the second linkage 73, the second linkage 73 can drive the included angle between the two first linkages 71 to decrease, so that both brake plates 3 can slide towards the track; when the brake linkage of brake 21 pushes the second linkage 73, the second linkage 73 can drive the included angle between the two first linkages 71 to increase, so that both brake plates 3 can slide away from the track.
[0066] Reference Figure 4 and Figure 6 In order to enable the brake slider 51 to automatically reset to the starting position, the brake mechanism 4 also includes a reset assembly 8, which includes a reset rack 81, a reset gear 82 and a reset coil spring 83.
[0067] A reset rack 81 is disposed within the force-increasing groove 31 and the force-reducing groove 35, and is positioned along the extending direction of the force-increasing groove 31 and the force-reducing groove 35. The reset rack 81 is located on the groove wall of the force-increasing groove 31 and the force-reducing groove 35 and is fixedly connected to the brake plate 3. A reset gear 82 is rotatably connected to the brake slider 51 and meshes with the reset rack 81. When the brake slider 51 slides, the reset gear 82 can rotate under the drive of the reset rack 81. A reset coil spring 83 is fixed between the reset gear 82 and the brake slider 51. The reset coil spring 83 is used to drive the reset gear 82 to rotate, so that the brake slider 51 can automatically return to the starting position.
[0068] Among them, reference Figure 6 The brake slider 51 has an annular relief groove 511 on its side wall. The reset gear 82 and the reset coil spring 83 are both located in the relief groove 511, and the meshing part of the reset rack 81 and the reset gear 82 is also located in the relief groove 511.
[0069] When the brake slider 51 slides away from the starting position, the reset gear 82 on the brake slider 51 can rotate under the drive of the reset rack 81. The rotating reset gear 82 can cause the reset coil spring 83 to accumulate elastic force. After the gantry crane body 1 stops, the brake 21 releases the braking force and allows the two brake plates 3 to slide away from the track. At this time, under the action of the elastic force accumulated by the reset coil spring 83, the reset gear 82 can reverse. The reverse reset gear 82 can drive the brake slider 51 to move back in the opposite direction under the meshing transmission of the reset rack 81, so that the brake slider 51 can automatically move back to reset.
[0070] Reference Figure 3 and Figure 5 In order to make the return and reset of the brake slider 51 less susceptible to resistance, when the two brake plates 3 slide to the farthest position, when the brake slider 51 slides to the position of the force-enhancing groove 31 closest to the track, a gap is left between the brake block 52 and the track.
[0071] When the brake 21 releases the braking force on the traveling wheel 2, the brake 21 can drive the two brake plates 3 to slide to the farthest position. At this time, a gap will be left between the brake block 52 and the track, so that there will be no friction between the brake block 52 and the track, thus making the reset of the brake slider 51 less susceptible to frictional resistance.
[0072] The implementation principle of the ultra-high speed low vacuum tube beam transport device in this application embodiment is as follows: When in use, when the brake 21 stops the traveling wheel 2, the brake 21 can drive the brake block 52 to elastically abut against the track through the linkage mechanism 7. Under the action of kinetic energy and wind force, the gantry crane body 1 carries the traveling wheel 2 and brake plate 3 to continue moving. The brake slider 51 slides in the force-increasing groove 31. The brake slider 51 drives the brake block 52 to continuously increase the friction force between it and the track. The brake slider 51 collides with multiple resistance plates 61 one by one. Under the elastic force of the resistance spring 622, the resistance plate 61 provides a blocking force to the brake slider 51, so that the brake slider 51 can provide the gantry crane body 1 with a gradually increasing point braking force. Thus, the braking capacity of the gantry crane is enhanced by the gradually increasing point braking method, and the risk of the gantry crane collapse is not easily increased.
[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
