Description

Technical Field

[0001] This invention relates to the field of flood discharge tunnel construction equipment technology, specifically to a steep slope material supply system. Background Technology

[0002] A spillway is a water discharge structure used to release excess water from a reservoir to ensure the safety of the dam. For inclined spillways, materials such as concrete need to be transported along the slope during construction.

[0003] Existing technologies have developed transport vehicles suitable for slope transportation. These vehicles can be divided into two types: one is an automated transport vehicle with a drive unit, control unit, and other functional units. Automated transport vehicles can achieve automated operation, but the economic cost of using them is relatively high; the other is a simpler transport vehicle with a simpler structure. The simpler transport vehicle is moved by external equipment such as a winch, thereby completing the material transportation.

[0004] When receiving materials at the end of a slope, such as pouring concrete into the vehicle, the concrete and other materials may fall outside the vehicle. This not only pollutes the construction environment and wastes materials, but also affects the use of the vehicle, especially simpler vehicles with more external equipment. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that materials fall outside when the transport vehicle receives materials. The purpose is to provide a steep slope feeding system to solve the above-mentioned problem.

[0006] This invention is achieved through the following technical solution:

[0007] A steep slope feeding system includes:

[0008] A transport vehicle, set up on a ramp, is used to travel back and forth along the ramp and transport materials;

[0009] A winch, located at the top of the ramp and connected to the transport vehicle by a traction rope, is used to drive the transport vehicle back and forth along the ramp.

[0010] A steering module, located at the top of the ramp, is used to steer the traction rope so that the winch is positioned outside the ramp extension; and

[0011] The shielding module is installed on the steering module and has a storage station that is housed on the steering module and a shielding station that extends outside the steering module.

[0012] In one possible design, the shielding module includes a shielding plate, a transmission unit, and a control unit;

[0013] The baffle is slidably mounted on the top cover of the steering module and connected to the top cover by a return spring, and there are multiple baffles;

[0014] The transmission unit is installed in the steering module and connects the baffle and the drive shaft of the steering module. Accordingly, the transmission unit is used to determine whether the drive shaft of the steering module transmits power to the baffle.

[0015] The control unit is mounted on the steering module and is used to monitor the distance between the vehicle and the steering module. Accordingly, when the control unit detects that the distance between the vehicle and the steering module is less than a preset value, the transmission unit connects to the drive shaft of the steering module and transmits power to the shield, so that the shield slides out of the steering module.

[0016] In one possible design, the transmission unit includes a transmission disc, an intermediate frame, and a control cylinder;

[0017] The top surface of the transmission disc is connected to the baffle plate through an arc-shaped groove, and the side of the transmission disc is connected to the intermediate frame through an intermediate gear.

[0018] The top of the intermediate frame meshes with the intermediate gear, and the bottom of the intermediate frame is connected to the control cylinder via the outwardly protruding first slider;

[0019] The control cylinder is mounted on the drive shaft, and a control groove is provided on the outer periphery of the control cylinder. Correspondingly, the first slider is slidably mounted in the control groove. A driver is provided outside the control cylinder to control its lifting and lowering along the drive shaft, so that the first slider slides to different positions in the control groove to control whether the drive shaft of the steering module transmits power to the baffle.

[0020] Correspondingly, the top of the drive shaft is connected to the drive disc, and the intermediate frame is fitted onto the drive shaft.

[0021] In one possible design, the control groove includes an upper annular groove, a transition groove, and a lower locking groove that are connected in sequence. The upper annular groove is annular, the transition groove has at least two and is evenly distributed around the circumference of the control cylinder, and the inner wall of the lower locking groove is used to abut against the first slider.

[0022] In one possible design, the controller includes a telescopic rod and a lifting spring, with the telescopic rod electrically connected to the control unit.

[0023] In one possible design, the telescopic rod is set at the upper end of the control cylinder and located inside the intermediate frame. A ring platform is provided on the drive shaft above the telescopic rod. Correspondingly, the upper end of the telescopic rod is mounted on the bottom surface of the ring platform, and the lower end of the telescopic rod is connected to the control cylinder.

[0024] The lifting spring is located at the lower end of the control cylinder, and transition rings are connected to both ends of the lifting spring. Correspondingly, the two ends of the lifting spring are connected to the control cylinder and the steering wheel of the steering module through the transition rings.

[0025] In one possible design, the side of the ring platform has an extended additional beam that extends below the intermediate gear and is used to mount the intermediate gear.

[0026] In one possible design, the shielding plate includes a base plate and a sub-plate. The base plate is slidably disposed on the top cover of the steering module and is connected to the transmission unit via a second slider. The sub-plate is provided with at least one and is slidably disposed on the base plate.

[0027] In one possible design, the second slider is provided with a limiter, which includes a first plate, a second plate, a third plate, and a limit shaft;

[0028] The first plate is connected to the second slider and is provided with a first limiting groove. The second plate is mounted on the steering module, and at least one end of the second plate is provided with a second limiting groove. The third plate is connected to the shield and is slidably mounted on the second slider. The limiting shaft is connected to the third plate, and one end of the limiting shaft is rotatably connected to the third plate via a torsion spring. The other end of the limiting shaft is provided with a first limiting wheel adapted to the first limiting groove and a second limiting wheel adapted to the second limiting groove.

[0029] Accordingly, when the second slider slides along the first direction, the first plate moves until the first limiting wheel is inserted into the first limiting groove, so that the third plate and the limiting shaft move accordingly, and the second limiting wheel disengages from the second limiting groove; when the second slider slides along the second direction, the first plate, the third plate, and the limiting shaft all move accordingly until the second limiting wheel is inserted into the second limiting groove, the limiting shaft rotates and drives the first limiting wheel to disengage from the first limiting groove;

[0030] Correspondingly, the first direction and the second direction are opposite to each other.

[0031] In one possible design, the steering module includes a housing, a rangefinder, steering wheels, and a drive shaft;

[0032] The housing includes an opening for the traction rope to enter and exit, and a top cover for installing the shielding module;

[0033] The rangefinder is installed at the opening of the container and faces the transport vehicle, and the rangefinder is electrically connected to the shielding module;

[0034] The steering wheel is mounted inside the housing and rotates via a drive shaft, and is used to change the direction of the traction rope.

[0035] The upper end of the drive shaft extends toward the top cover and connects to the shielding module.

[0036] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0037] On the one hand, a steering module is installed to change the direction of the traction rope, allowing the winch to be positioned on the outside of the ramp extension. When the transport vehicle is parked at the top of the ramp, the transport vehicle and the winch are staggered. The relatively small size of the steering module effectively shortens the distance between the transport vehicle and the transport equipment. On the other hand, a shielding module is installed to shield and protect the surrounding area in case of material falling, thus preventing pollution of the construction environment.

[0060] Example:

[0061] like Figures 1-15 As shown, a steep slope feeding system includes:

[0062] The transport vehicle 100 is set on the ramp and is used to travel back and forth along the ramp and transport materials.

[0063] A winch 200 is installed at the top of the ramp and connected to a transport vehicle 100 by a traction rope, used to drive the transport vehicle 100 back and forth along the ramp.

[0064] Steering module 300, located at the top of the ramp, is used to steering the traction rope so that the winch 200 is positioned outside the ramp extension; and

[0065] The shielding module 400 is mounted on the steering module 300 and has a storage station on the steering module 300 and a shielding station extending outside the steering module 300.

[0066] In the steep slope feeding system, the winch 200 is connected to the transport vehicle 100 via a traction rope. The power of the winch 200 is transmitted to the transport vehicle 100 via the traction rope, thereby driving the transport vehicle 100 to move up and down the slope. If the winch 200 is located on the extension line of the top of the slope, when the transport vehicle 100 is parked at the top of the slope, the transport vehicle 100 and the winch 200 are on the same straight line. When transport vehicles or other transport equipment pour materials into the transport vehicle 100, the winch 200 increases the distance between the transport vehicle 100 and the transport equipment, making it more difficult to pour materials in and increasing the likelihood of materials falling out of the transport vehicle 100.

[0067] To address this, the steep slope material supply system incorporates a steering module 300. This module changes the direction of the traction rope, allowing the winch 200 to be positioned on the outer side of the slope extension. When the transport vehicle 100 is parked at the top of the slope, the transport vehicle 100 and the winch 200 are staggered. The relatively small size of the steering module 300 effectively shortens the distance between the transport vehicle 100 and the transport equipment. Furthermore, a shielding module 400 is included. Even if materials fall, the shielding module 400 provides protection to the surrounding area, preventing pollution of the construction environment.

[0068] It is worth noting that any suitable existing functional module can be installed near the steering module 300 to meet the corresponding construction requirements, while the shielding module 400, when unfolded, increases in size, covering the towing rope, functional modules, etc., and providing protection. Correspondingly, the shielding module 400 can also remain in the unfolded state, providing space for the installation of additional functional modules and expanding the uses of the shielding module 400.

[0069] In one possible implementation, the shielding module 400 includes a shielding plate 1, a transmission unit 2, and a control unit;

[0070] The baffle plate 1 is slidably mounted on the top cover of the steering module 300 and connected to the top cover by a return spring, and multiple baffle plates 1 are provided;

[0071] The transmission unit 2 is installed in the steering module 300 and connects the baffle plate 1 and the drive shaft 504 of the steering module 300. Accordingly, the transmission unit 2 is used to determine whether the drive shaft 504 of the steering module 300 transmits power to the baffle plate 1.

[0072] The control unit is mounted on the steering module 300 and is used to monitor the distance between the vehicle 100 and the steering module 300. Accordingly, when the control unit detects that the distance between the vehicle 100 and the steering module 300 is less than a preset value, the transmission unit 2 is connected to the drive shaft 504 of the steering module 300 and transmits power to the baffle plate 1 so that the baffle plate 1 slides out of the steering module 300.

[0073] Based on the above design, the steering module 300 includes a steering wheel 503. The traction rope passes around the steering wheel 503 to achieve steering. The steering wheel 503 rotates synchronously as the winch 200 winds up and unwinds the traction rope. In the shielding module 400, the control unit and the shielding unit are connected to the steering wheel 503 via a drive shaft 504. The rotation of the steering wheel 503 then powers the sliding of the shielding plate 1, reducing the number of drive devices in the shielding module 400, resulting in a simpler structure and better economic efficiency.

[0074] After the baffle 1 is moved outward by the rotation of the steering wheel 503, the return spring (any suitable existing model of spring can be selected) provides elastic force and is used to reset the baffle 1, thereby realizing the reciprocating sliding of the baffle 1 in the top cover, and thus realizing the expansion and contraction of the baffle module 400. Based on the reset of the baffle 1, the return spring can be installed in any suitable position, and the present invention does not impose any restrictions on this.

[0075] Furthermore, multiple shielding plates 1 are provided to increase the shielding range and area of ​​the shielding module 400.

[0076] The transmission unit 2 and the control unit cooperate with each other. Under normal circumstances, the transmission unit 2 does not transmit power, so that the shielding module 400 is in the retracted state. When the control unit detects that the distance between the carrier vehicle 100 and the steering module 300 is less than a preset value, the transmission unit 2 connects to the drive shaft 504 of the steering module 300 and transmits power to the shielding plate 1, so that the shielding plate 1 slides out of the steering module 300 and the shielding module 400 is in the unfolded state.

[0077] It is worth noting that if the baffle 1 needs to extend outside the top cover for an extended period of time, the staff can choose any suitable existing snap-fit ​​component and use the snap-fit ​​component to hold the baffle 1 in place, thereby overcoming the elastic force of the return spring.

[0078] It is easy to understand that the control unit can be any suitable existing model, with a wide range of choices, which can better adapt to the corresponding working environment.

[0079] Optionally, such as Figures 4-9 As shown, the transmission unit 2 includes a transmission disc 201, an intermediate frame 202, and a control cylinder 203;

[0080] The top surface of the transmission disc 201 is connected to the baffle plate 1 through the arc-shaped slide groove 204, and the side of the transmission disc 201 is connected to the intermediate frame 202 through the intermediate gear 205.

[0081] The top of the intermediate frame 202 meshes with the intermediate gear 205, and the bottom of the intermediate frame 202 is connected to the control cylinder 203 through the protruding first slider 206;

[0082] The control cylinder 203 is mounted on the drive shaft 504. A control groove is provided on the outer periphery of the control cylinder 203. Correspondingly, the first slider 206 is slidably mounted in the control groove. The control cylinder 203 is provided with a driver 3 for controlling its lifting and lowering along the drive shaft 504, so that the first slider 206 slides to different positions in the control groove to control whether the drive shaft 504 of the steering module 300 transmits power to the baffle plate 1.

[0083] Correspondingly, the top of the drive shaft 504 is connected to the drive disc 201, and the intermediate frame 202 is sleeved on the drive shaft 504.

[0084] Based on the above design, the transmission disk 201 is connected to the baffle plate 1 via the first slider 206, and the arc-shaped sliding groove 204 pushes the first slider 206 and the baffle plate 1 to slide outward. The side of the transmission disk 201 is provided with an external gear ring, which meshes with the intermediate frame 202 via the intermediate gear 205. Correspondingly, the intermediate frame 202 is provided with a matching internal gear ring.

[0085] The control cylinder 203 controls whether the drive shaft 504 transmits power to the baffle plate 1 via the control groove. Specifically: Figure 7 As shown, the control groove includes an upper annular groove 207, a transition groove 208 and a lower locking groove 209 connected in sequence. The upper annular groove 207 is annular, the transition groove 208 has at least two and is evenly distributed in the circumference of the control cylinder 203, and the inner wall of the lower locking groove 209 is used to abut against the first slider 206.

[0086] When the control cylinder 203 is connected to the first slider 206 through the upper annular groove 207, the drive shaft 504 and the control cylinder 203 rotate synchronously, and the first slider 206 slides along the upper annular groove 207. That is, the upper annular groove 207 cannot abut against the first slider 206 and form a mechanical limit, thus preventing the intermediate frame 202 from moving. Conversely, when the control cylinder 203 moves upward, the first slider 206 slides out of the upper annular groove 207 and slides into the lower slot 209 through the transition groove 208. If the drive shaft 504 and the control cylinder 203 rotate counterclockwise synchronously, the inner wall of the lower slot 209 abuts against the first slider 206 and slides, driving the first slider 206 and the intermediate frame 202 to rotate synchronously through mechanical limit, thereby driving the transmission disc 201 to rotate, and finally realizing the outward sliding of the baffle plate 1. Conversely, when the drive shaft 504 and the control cylinder 203 rotate clockwise synchronously, the first slider 206 slides along the lower slot 209 into the transition slot 208 and returns to the upper annular slot 207. The control cylinder 203 moves down synchronously, thereby cutting off the mechanical limit between the lower slot 209 and the first slider 206, and the drive shaft 504 will not transmit power to the baffle plate 1.

[0087] It is worth noting that the rotating disk is connected to the drive shaft 504 via bearings so that the two can move independently.

[0088] It is easy to understand that, based on the internal gear ring, the intermediate frame 202 can be constructed into any suitable structure, with diverse structures to better adapt to different operational requirements.

[0089] In addition, the inner circumference of the control cylinder 203 is provided with an inner groove structure, such as Figure 8 As shown, the inner groove includes an inner transition groove 210 and an inner locking groove 211. The upper and lower ends of the inner transition groove 210 are respectively connected to an inner locking groove 211, and the connection between the inner transition groove 210 and the inner locking groove 211 is located in the middle of the inner locking groove 211. Correspondingly, the drive shaft 504 is provided with an inner slider adapted to the inner groove. Based on this, when the control cylinder 203 is connected to the first slider 206 through the upper annular groove 207 or the lower slot 209, the inner circumference of the control cylinder 203 is connected to the inner slider of the transmission shaft 504 through the inner slot 211. The inner slider slides along the inner slot 211 and abuts against the side wall of the inner slot 211, so that the transmission shaft 504 and the control cylinder 203 rotate synchronously. When the control cylinder 203 moves up and down, the outer circumference of the control cylinder 203 is connected to the first slider 206 through the transition groove 208, and at the same time, the inner circumference of the control cylinder 203 is connected to the inner slider through the inner transition groove 210, thereby realizing the switching of the position of the control cylinder 203. Accordingly, the transition groove 208 and the inner transition groove 210 are located in the same position, so that the first slider 206 and the inner slider slide synchronously along the axial direction of the control cylinder 203.

[0090] Accordingly, the controller moves the control cylinder 203 up and down, thereby controlling the connection between the first slider 206 and the control cylinder 203 (i.e., the part of the first slider 206 in the control groove). The controller includes a telescopic rod 301 and a lifting spring 302, with the telescopic rod 301 electrically connected to the control unit. Based on the above design, the telescopic rod 301 can move the control cylinder 203 up and down by extending and retracting, and its electrical connection to the control unit enables automated operation. The lifting spring 302 is also provided; when the control cylinder 203 is at its lower limit position, it bears the weight and lifts the control cylinder 203. This stops the telescopic rod 301, reducing its working time, and also prevents the first slider 206 from contacting the inner wall of the annular groove 207, reducing wear.

[0091] Optionally, such as Figure 4 and Figure 5 As shown, the telescopic rod 301 is set on the upper end of the control cylinder 203 and located inside the intermediate frame 202. The drive shaft 504 is provided with a ring platform 505 located above the telescopic rod 301. Correspondingly, the upper end of the telescopic rod 301 is installed on the bottom surface of the ring platform 505, and the lower end of the telescopic rod 301 is connected to the control cylinder 203.

[0092] The lifting spring 302 is located at the lower end of the control cylinder 203. Both ends of the lifting spring 302 are connected to transition rings 303. Correspondingly, the two ends of the lifting spring 302 are connected to the control cylinder 203 and the steering wheel 503 of the steering module 300 through the transition rings 303 respectively.

[0093] Based on the above design scheme, the drive shaft 504 provides space for the installation of the telescopic rod 301 by setting the ring platform 505. Multiple telescopic rods 301 can be set. On the one hand, they can share the weight of the control cylinder 203 and reduce the load on a single telescopic rod 301. On the other hand, the control cylinder 203 can be raised and lowered synchronously as a whole by multiple telescopic rods 301 working together, thus reducing wear.

[0094] The lifting spring 302 is prevented from rotating with the steering wheel 503 or the control cylinder 203 by the transition ring 303. Accordingly, the control cylinder 203 and the steering wheel 503 are provided with grooves that fit the transition ring 303.

[0095] In one possible implementation, an additional beam 506 extends outward from the side of the ring platform 505, extending below the intermediate gear 205 and used to mount the intermediate gear 205. Based on the above design, the additional beam 506 is provided on the ring platform 505 to provide installation space for the intermediate gear 205.

[0096] In one possible implementation, the shield 1 includes a base plate 101 and a sub-plate 102. The base plate 101 is slidably disposed on the top cover of the steering module 300, and the base plate 101 is connected to the transmission unit 2 through a second slider. The sub-plate 102 is provided with at least one and slidably disposed on the base plate 101.

[0097] Based on the above design, the shielding area of ​​the shielding plate 1 can be further expanded by setting the sub-plate 102. That is, when the sub-plate 102 slides out of the substrate 101, the shielding plate 1 achieves shielding through the substrate 101 and the sub-plate 102 together, greatly increasing the shielding area. Moreover, the sub-plate 102 can be selected to slide out or not, making it flexible in use.

[0098] Accordingly, the substrate 101 is provided with a driving device for driving the sub-board 102 to slide back and forth. The driving device can be any suitable existing device, which will not be listed here.

[0099] Optionally, such as Figure 12As shown, an embodiment of the shielding plate 1 is provided: both the base plate 101 and the sub-plate 102 are square, and there are two sub-plates 102. The base plate 101 is divided into four equal-area regions: one is a transmission area 103 with a second slider connected to the transmission disk 201; the second is a driving area 104 located diagonally opposite to the transmission area 103, where the driving device is located; and the third is two mounting areas 105 for mounting the sub-plates 102. When the shielding plate 1 slides out, the transmission area 103 remains in the top cover, while the driving area 104 and the mounting area 105 are both located outside the top cover and can be driven by the driving device to move the sub-plates 102 out of the base plate 101.

[0100] And it is easy to understand that by having multiple shields 1 work together, the shielding area of ​​the shields 1 can be greatly increased.

[0101] In one possible implementation, a limiter is provided on the second slider. Based on the above design, the limiter is used to restrict the sliding distance of the baffle 1, thereby improving the movement accuracy of the baffle 1 and ensuring that the extreme position of the baffle 1 is within the design range.

[0102] Optionally, such as Figures 13-15 As shown, the limiter includes a first plate 401, a second plate 402, a third plate 403, and a limit shaft 404;

[0103] The first plate 401 is connected to the second slider and is provided with a first limiting groove 405. The second plate 402 is disposed on the steering module 300, and at least one end of the second plate 402 is provided with a second limiting groove 406. The third plate 403 is connected to the shielding plate 1 and is slidably disposed on the second slider. The limiting shaft 404 is connected to the third plate 403, and one end of the limiting shaft 404 is rotatably connected to the third plate 403 through a torsion spring. The other end of the limiting shaft 404 is provided with a first limiting wheel 407 adapted to the first limiting groove 405 and a second limiting wheel 408 adapted to the second limiting groove 406.

[0104] Accordingly, when the second slider slides along the first direction, the first plate 401 moves until the first limiting wheel 407 is inserted into the first limiting groove 405, so that the third plate 403 and the limiting shaft 404 move along, and the second limiting wheel 408 disengages from the second limiting groove 406; when the second slider slides along the second direction, the first plate 401, the third plate 403 and the limiting shaft 404 all move along, until the second limiting wheel 408 is inserted into the second limiting groove 406, the limiting shaft 404 rotates and drives the first limiting wheel 407 to disengage from the first limiting groove 405;

[0105] Correspondingly, the first direction and the second direction are opposite to each other.

[0106] Based on the above design, the limiting shaft 404 is rotatably connected to the third plate 403 via a torsion spring. When the second slider slides until the first plate 401 engages with the first limiting wheel 407 through the first limiting groove 405, the limiting shaft 404 is pushed by the mechanical limiting of the first limiting groove 405. The limiting shaft 404 rotates, causing the torsion spring to be compressed and deformed, so that the first plate 401 and the third plate 403 are connected and slide synchronously. Conversely, when the second slider slides and approaches the second limiting groove 406, the limiting shaft 404 has room to move and rotates under the drive of the torsion spring, so that the second limiting wheel 408 is inserted into the second limiting groove 406, the first limiting wheel 407 disengages from the first limiting groove 405, the connection between the first plate 401 and the third plate 403 is released, and the sliding of the second slider will not be transmitted to the blocking plate 1 through the limiter, so that the blocking plate 1 stays in the preset position.

[0107] It is worth noting that by adjusting the position of the limiter, the sliding distance of the baffle 1 is further limited, thereby controlling the length of the baffle 1 sliding out of the top cover and the covering area of ​​the baffle 1.

[0108] Preferably, such as Figures 13-15 As shown, both the first plate 401 and the third plate 403 have outward protrusions 409 in the portion provided in the limiting groove. The outward protrusions 409 extend between the first limiting wheel 407 and the second limiting wheel 408. Based on this, when the second slider slides, the first plate 401 or the third plate 403 abuts against the corresponding limiting wheel through the outward protrusions 409, realizing the abutment between the limiting wheel and the inner wall of the limiting groove. This, in turn, drives the limiting shaft 404 to rotate better through relative motion, allowing the corresponding limiting wheel to be better inserted into the corresponding limiting groove, and the third plate 403 to switch the connection relationship more easily.

[0109] In one possible implementation, the steering module 300 includes a housing 501, a rangefinder 502, a steering wheel 503, and a drive shaft 504;

[0110] The housing 501 includes an opening for the traction rope to enter and exit and a top cover for mounting the shielding module 400;

[0111] The rangefinder 502 is located at the opening of the housing 501 and faces the transport vehicle 100, and the rangefinder 502 is electrically connected to the shielding module 400.

[0112] The steering wheel 503 is rotatably mounted inside the housing 501 via the drive shaft 504 and is used to change the direction of the traction rope.

[0113] The upper end of the drive shaft 504 extends toward the top cover and connects to the shielding module 400.

[0114] Based on the above design, the housing 501 can be constructed into any suitable shape. The top cover of the housing 501 should be adapted and modified to facilitate the installation of the shielding plate 1. The rangefinder 502 is used to measure the distance between the transport vehicle 100 and the steering module 300, thereby controlling whether the shielding module 400 moves outward and unfolds. The rangefinder 502 can be any suitable existing model, and the present invention does not impose any restrictions on it. The outer peripheral surface of the steering wheel 503 preferably has a concave groove, and the traction rope passes around the concave groove, which helps to reduce the probability of the traction rope detaching from the steering wheel 503.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
