Description

Technical Field

[0001] This invention relates to the field of mining transport vehicle technology, specifically an explosion-proof diesel engine trackless rubber-tired vehicle. Background Technology

[0002] In coal mine underground auxiliary transportation systems, the surface environment of mine roadways is complex, often accompanied by undulating slopes, muddy water accumulation, and uneven road surfaces. When ordinary vehicles travel on inclined roads, the vehicle body will tilt, causing the center of gravity of the vehicle to shift. The cargo is prone to sliding on the inclined carriage, which exacerbates the uneven distribution of load. If the center of gravity shift is too large, it will not only increase the difficulty of steering and braking, but may even cause rollover accidents in severe cases, threatening the safety of people and machines. Explosion-proof diesel engine trackless rubber-tired vehicles are widely used because of their flexibility and efficiency.

[0003] In the existing technology, some rubber-tired vehicles are equipped with adjustable leveling suspension or automatic cab controllers. However, these systems usually require modification of the vehicle chassis or the entire frame, which involves significant structural changes and high costs. The leveling mechanism is mostly a rigid lifting mechanism with a slow response speed, making it difficult to adapt to the frequently changing slopes underground. It fails to effectively solve the problem of cargo slippage and vehicle center of gravity imbalance caused by the large tilt of the cargo platform with the vehicle body. Therefore, there is a need for a device that can independently and flexibly adjust the angle of the cargo platforms on both sides without changing the cab, power system, and main chassis structure, so as to actively maintain the lateral balance and load stability of the vehicle body in real time. Summary of the Invention

[0004] The purpose of this invention is to provide an explosion-proof diesel engine trackless rubber-tired vehicle to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an explosion-proof diesel engine trackless rubber-tired vehicle, comprising a front end, a body, detection elements, a controller, a pair of cargo plates, and a pair of control components. The body is connected to the front end via a traction component. A driver's cab is provided on one side of the front end. The pair of cargo plates are symmetrically arranged, with the sides of the two cargo plates close to each other rotatably connected to the body. The two control components are connected between each cargo plate and the body. The pair of cargo plates are used to load goods, and the two cargo plates are rotatably connected to the middle of the body. The control components adjust the angle of the cargo plates. When the vehicle is traveling on an inclined road, the control components use the cargo plates to adjust the height of the lower side and lower the height of the higher side, so that the vehicle remains balanced and the center of gravity remains stable.

[0006] Each of the aforementioned control components includes at least two sets of adjustment sections and a power section. The detection element, controller, and power section are electrically connected. Each set of adjustment sections includes a pair of lower inclined slides, a pair of upper straight slides, and a spindle. The pair of lower inclined slides are connected to the vehicle body, and the pair of upper straight slides are connected to the cargo plate. Each upper straight slide is equipped with an upper slider, and each lower inclined slide is equipped with a lower slider. The spindle is connected to the two upper sliders and the two lower sliders. The power section is connected to the spindle in each set of adjustment sections.

[0007] Furthermore, each of the upper straight slide blocks has a convex-shaped groove at its bottom, and the upper part of each of the lower inclined slide blocks is an inclined surface. The inclined surface of the lower inclined slide block also has a convex-shaped groove. The upper slide block is slidably connected to the convex-shaped groove of the upper straight slide block through a convex-shaped locking block, and the lower slide block is slidably connected to the convex-shaped groove of the lower inclined slide block through a convex-shaped locking block.

[0008] Furthermore, a pair of lower sliders are symmetrically arranged at both ends of the spindle, and the pair of lower sliders are rotatably connected to the spindle. A pair of upper sliders are symmetrically arranged in the middle section of the spindle, and the pair of upper sliders are also rotatably connected to the spindle. The power unit is connected to the center of symmetry of the spindle. Since there is an angle between the lower inclined slide and the upper straight slide, and the cargo plate deflects around the axis, the upper straight slide also forms an angle with the vehicle body after the cargo plate deflects and moves. The upper and lower sliders are hinged through the spindle. When the power unit drives the spindle to move, the upper and lower sliders are passively adjusted in angle during sliding, so that the convex locking block remains in the convex sliding groove. The angle between the cargo plate and the vehicle body is adjusted with the movement of the spindle.

[0009] Furthermore, the power unit includes a pair of hydraulic cylinders and a hydraulic system. The pair of hydraulic cylinders are connected to the hydraulic system via pipelines. The cylinder body of each hydraulic cylinder is rotatably connected to the vehicle body via a support, and the piston of each hydraulic cylinder is connected to the center of the spindle. When the vehicle body tilts during driving, the level detector detects the tilt state of the vehicle body. The level detector transmits the tilt signal of the vehicle body to the controller through a circuit. The controller is connected to the hydraulic system circuit. The controller uses the tilt signal of the vehicle body to drive the hydraulic system to operate. The hydraulic pump in the hydraulic system starts, and the solenoid valve of the hydraulic circuit opens and closes according to the signal, thereby pumping hydraulic oil into the hydraulic cylinder and controlling the movement of the hydraulic cylinder. Hydraulic oil is added to the hydraulic cylinder tilted to the lower side of the hydraulic system. The piston of the hydraulic cylinder pushes outward, and the piston pushes the spindle to move. The spindle drives the lower slide block to slide along the inclined surface of the lower slide block. The height of the spindle increases with the increase of the lower slide block. The cylinder body of the hydraulic cylinder adjusts its angle on the vehicle body accordingly with the movement of the spindle. The upper slide block moves synchronously with the increase of the spindle. The upper straight slide block is lifted, and the cargo plate tilted to the lower side of the vehicle body is correspondingly raised. The hydraulic system draws hydraulic oil from the hydraulic cylinder on the higher side, causing the piston of the hydraulic cylinder to retract inward. The spindle drives the lower slider to slide downward along the slope of the lower inclined slide block. The upper slider moves synchronously as the spindle lowers, and the upper straight slide block descends, correspondingly lowering the height of the cargo plate on the higher side of the vehicle. Using the vehicle tilt signal, the hydraulic cylinder drives the cargo plate to deflect, adjusting the tilt angle of the cargo plate relative to the vehicle body, raising the lower side. After the vehicle body is leveled, the level detector detects that the vehicle body is balanced. The controller converts the signal fed back by the level detector into a signal to stop the hydraulic system, and the hydraulic pump stops running, thereby adjusting the balance of the vehicle body and the stability of the center of gravity.

[0010] Furthermore, the power unit includes a winding device, a movable pulley, a fixed pulley, a pulley seat, and a pulley cable. The movable pulley is installed at the center of symmetry of the spindle. The winding device and the pulley seat are installed on the vehicle body. The fixed pulley is rotatably installed on the pulley seat. One end of the pulley cable is connected to the pulley seat. The pulley cable passes around the movable pulley and the fixed pulley in sequence. The other end of the pulley cable is connected to the winding device.

[0011] Furthermore, the power unit also includes a servo motor, a drive gear, a synchronous shaft, and a driven gear. The servo motor is mounted on the vehicle body, the drive gear is connected to the motor shaft of the servo motor, the synchronous shaft is connected between a pair of winding devices, and the driven gear is mounted on the synchronous shaft. The drive gear and the driven gear are meshed together. When the vehicle body tilts during driving, the servo motor on the lower side is energized, driving the drive gear to rotate. The drive gear, through the driven gear, drives the synchronous shaft to rotate, which in turn drives the winding devices. The winding devices, depending on the direction of rotation of the synchronous shaft, either wind up or unwind the pulley cable.

[0012] Furthermore, the winding device includes a winding drum, a threaded sleeve, and a splined shaft. The splined shaft is rotatably connected to the winding device. A splined groove is formed in the middle of the winding drum, which is slidably mounted on the splined shaft via the splined groove. The threaded sleeve is fixedly connected to the winding device. A threaded ring is provided on the side of the winding drum near the threaded sleeve, and the threaded ring is helically connected to the threaded sleeve. A synchronous shaft drives the splined shaft to rotate, which in turn drives the winding drum to rotate. Simultaneously, the winding drum rotates, causing the threaded ring to rotate. As the threaded ring rotates, the threaded sleeve remains stationary, allowing the threaded ring to move while rotating. This causes the winding drum to move axially along the splined shaft, evenly winding the pulley cable onto the winding drum.

[0013] Furthermore, both ends of the synchronous shaft are connected to a spline shaft, and one end of the pulley cable passes through the winding machine and is wound around the winding drum. When the winding drum winds the pulley cable, the pulley cable drives the movable pulley to move. The movable pulley slides along the inclined surface of the lower sliding block along with the spindle, and the upper sliding block moves synchronously as the spindle rises. The upper straight sliding block is lifted, and the cargo plate tilted to the lower side of the vehicle body is correspondingly raised. When the winding drum unwinds the pulley cable, the weight of the cargo plate is transmitted downwards through the upper straight sliding block and the upper sliding block to the lower sliding block. After the pulley cable becomes slack, the lower sliding block immediately slides downwards along the inclined surface of the lower sliding block. The longer the unwound pulley cable, the more the upper straight sliding block descends, and the cargo plate on the higher side of the vehicle body is correspondingly lowered.

[0014] The pressure generated after the cargo is loaded onto the cargo platform is transmitted to the spindle. Through the setting of the movable pulley, half of the pressure is transmitted to the winding drum via the pulley cable, which reduces the working load of the servo motor, makes the adjustment of the cargo platform more flexible, enhances the stability when adjusting the vehicle body, and maintains the stability of the vehicle body's center of gravity.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By rotating the cargo platform to the vehicle body and setting adjustment components on each side, the angle of the cargo platform on both sides can be independently adjusted. When the vehicle is driving on an inclined road, the power unit can independently drive the lower side spindle to rise along the slope to raise the cargo platform, or drive the higher side spindle to descend along the slope to lower the cargo platform. The lever compensation counteracts the body roll angle, keeping the vehicle's center of gravity in a stable range. This greatly improves the vehicle's anti-rollover ability under complex road conditions and enhances driving stability.

[0016] 2. The servo motor drives the winding device, and the combination of movable and fixed pulleys drives the transmission. Part of the weight of the cargo plate and the cargo is converted into rope tension through the movable pulley, so that the motor only needs to bear about half of the effective load. This significantly reduces the output torque requirement of the power components, making the angle adjustment action more convenient and flexible, and avoiding the leakage risks of the hydraulic system.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-6 As shown, Embodiment 1 of the present invention: an explosion-proof diesel engine trackless rubber-tired vehicle includes a front end 1, a body 3, detection elements, a controller, a pair of cargo plates 4, and a pair of control components 5. The body 3 is connected to the front end 1 via a traction member. A driver's cab 2 is provided on one side of the front end 1. The pair of cargo plates 4 are symmetrically arranged, and the side of the two cargo plates 4 that is close to each other is rotatably connected to the body 3. The two control components 5 are connected between each cargo plate 4 and the body 3. The pair of cargo plates 4 are used to load goods. The two cargo plates 4 are rotatably connected to the middle of the body 3. The control components 5 adjust the angle of the cargo plates 4. When the body 3 is traveling on an inclined road, the control components 5 use the cargo plates 4 to adjust the height of the lower side and the height of the higher side, so that the body 3 remains balanced and the center of gravity remains stable.

[0021] Each control component 5 includes at least two sets of adjustment sections and power sections, a detection element, a controller, and a power section circuit connection. The detection element is a level detector. Each set of adjustment sections includes a pair of downward inclined slides 16, a pair of upward straight slides 17, and a spindle 20. The pair of downward inclined slides 16 are connected to the vehicle body 3, and the pair of upward straight slides 17 are connected to the cargo plate 4. Each upward straight slide 17 is equipped with an upper slider 18, and each downward inclined slide 16 is equipped with a downward slider 19. The spindle 20 is connected to the two upper sliders 18 and the two downward sliders 19. The power section is connected to the spindle 20 in each set of adjustment sections. Each upward straight slide 17 has a convex-shaped groove at its bottom, and the upper part of each downward inclined slide 16 is an inclined surface. The inclined surface of the downward inclined slide 16 also has a convex-shaped groove. The upper slider 18 slides with the convex-shaped groove of the upward straight slide 17 through a convex-shaped locking block, and the lower slider 19 slides with the convex-shaped groove of the downward inclined slide 16 through a convex-shaped locking block. A pair of lower sliders 19 are symmetrically arranged at both ends of the spindle 20 and are rotatably connected to the spindle 20. A pair of upper sliders 18 are symmetrically arranged in the middle section of the spindle 20 and are also rotatably connected to the spindle 20. The power unit is connected to the center of symmetry of the spindle 20.

[0022] Because there is an angle between the lower inclined slide block 16 and the upper straight slide block 17, and the cargo plate 4 deflects around the axis, after the cargo plate 4 deflects and moves, the upper straight slide block 17 also forms an angle with the vehicle body 3. The upper slide block 18 and the lower slide block 19 are hinged by the spindle 20. When the power unit drives the spindle 20 to move, the upper slide block 18 and the lower slide block 19 are passively adjusted in angle during sliding, so that the convex locking block is kept sliding in the convex groove. The angle between the cargo plate 4 and the vehicle body 3 is adjusted with the movement of the spindle 20.

[0023] The power unit includes a pair of hydraulic cylinders and a hydraulic system. The pair of hydraulic cylinders are connected to the hydraulic system through pipelines. The cylinder body of each hydraulic cylinder is rotatably connected to the vehicle body 3 through a support. The piston of each hydraulic cylinder is connected to the center of the spindle 20. When the vehicle body 3 tilts during driving, the level detector detects the tilt state of the vehicle body. The level detector transmits the tilt signal of the vehicle body to the controller through the circuit. The controller is connected to the hydraulic system circuit. The controller uses the tilt signal of the vehicle body to drive the hydraulic system to operate. The hydraulic pump in the hydraulic system starts, and the solenoid valve of the hydraulic circuit opens and closes according to the signal. Then, the hydraulic oil is pumped into the hydraulic cylinder to control the movement of the hydraulic cylinder. The hydraulic cylinder tilted to the lower side is filled with hydraulic oil, and the piston of the hydraulic cylinder pushes outward. The piston pushes the spindle 20 to move. The spindle 20 drives the lower slide block 19 to slide along the inclined surface of the lower inclined slide block 16. The height of the spindle 20 increases with the increase of the lower slide block 19. The cylinder body of the hydraulic cylinder adjusts the angle of the body body 3 accordingly with the movement of the spindle 20. The upper slide block 18 moves synchronously with the increase of the spindle 20. The upper straight slide block 17 is lifted, and the cargo plate 4 tilted to the lower side of the body body 3 is correspondingly raised. The hydraulic system draws hydraulic oil from the hydraulic cylinder on the higher side, causing the piston of the hydraulic cylinder to retract inward. The spindle 20 drives the lower slider 19 to slide downward along the slope of the lower inclined slide 16. The upper slider 18 moves synchronously as the spindle 20 lowers, and the upper straight slide 17 descends. The cargo plate 4 on the higher side of the vehicle body 3 is lowered accordingly. The hydraulic cylinder is controlled by the tilt signal of the vehicle body 3 to deflect the cargo plate 4, adjusting the tilt angle of the cargo plate 4 relative to the vehicle body 3, raising the lower side. After the vehicle body is leveled, the level detector detects that the vehicle body is balanced. The controller converts the signal fed back by the level detector into a signal to stop the hydraulic system. The hydraulic pump stops running, thereby adjusting the balance and stability of the center of gravity of the vehicle body 3.

[0024] Embodiment 2 of the present invention: A power unit different from that in Embodiment 1 is provided. The difference is that this embodiment uses a set of movable pulleys 21 instead of a hydraulic cylinder to reduce the output force of the power unit when adjusting the cargo plate 4, making the adjustment of the cargo plate 4 more flexible and enhancing the stability when adjusting the vehicle body 3. Specifically, the power unit includes a winder 11, a movable pulley 21, a fixed pulley 22, a pulley seat 23, and a pulley cable 24. The movable pulley 21 is mounted at the center of symmetry of the spindle 20. The winder 11 and the pulley seat 23 are mounted on the vehicle body 3. The fixed pulley 22 is rotatably mounted on the pulley seat 23. One end of the pulley cable 24 is connected to the pulley seat 23, and the pulley cable 24 passes sequentially around the movable pulley 21 and the fixed pulley 22. The other end of the pulley cable 24 is connected to the winder 11. The power unit also includes a servo motor 7, a drive gear 8, a synchronous shaft 9, and a driven gear 10. The servo motor 7 is mounted on the vehicle body 3. The drive gear 8 is connected to the motor shaft of the servo motor 7. The synchronous shaft 9 is connected between a pair of winders 11. The driven gear 10 is mounted on the synchronous shaft 9, and the drive gear 8 and the driven gear 10 are meshed together. When the vehicle body 3 tilts during driving, the servo motor 7 on the lower side is powered on and drives the drive gear 8 to rotate. The drive gear 8 drives the synchronous shaft 9 to rotate through the driven gear 10. The synchronous shaft 9 drives the winder 11 to work. The winder 11 winds up or releases the pulley cable 24 according to the direction of rotation of the synchronous shaft 9.

[0025] The winding device 11 houses a winding drum 12, a threaded sleeve 14, and a splined shaft 15. The splined shaft 15 is rotatably connected to the winding device 11. The winding drum 12 has a splined groove in its middle, and it is slidably mounted on the splined shaft 15 through the splined groove. The threaded sleeve 14 is fixedly connected to the winding device 11. A threaded ring 13 is provided on the side of the winding drum 12 near the threaded sleeve 14, and the threaded ring 13 is helically connected to the threaded sleeve 14. Both ends of the synchronous shaft 9 are connected to the splined shaft 15. One end of the pulley cable 24 passes through the winding device 11 and is wound around the winding drum 12. Synchronous shaft 9 drives spline shaft 15 to rotate. During the rotation of spline shaft 15, take-up drum 12 is driven to rotate. While rotating, take-up drum 12 drives threaded ring 13 to rotate. When threaded ring 13 rotates, threaded sleeve 14 remains stationary, so that threaded ring 13 rotates and moves at the same time. Take-up drum 12 then moves along the axial direction of spline shaft 15, so that pulley cable 24 is evenly wound onto take-up drum 12.

[0026] When the winding drum 12 winds up the pulley cable 24, the pulley cable 24 drives the movable pulley 21 to move. The movable pulley 21 slides along the inclined surface of the lower sliding block 16 with the spindle 20. The upper sliding block 18 moves synchronously with the rise of the spindle 20, and the upper straight sliding block 17 is lifted. The cargo plate 4, which is tilted to the lower side of the vehicle body 3, is correspondingly raised. When the winding drum 12 unwinds the pulley cable 24, the weight of the cargo plate 4 is transmitted downward through the upper straight sliding block 17 and the upper sliding block 18 to the lower sliding block 19. After the pulley cable 24 becomes slack, the lower sliding block 19 slides downward along the inclined surface of the lower sliding block 16. The longer the unwound pulley cable 24 is, the more the upper straight sliding block 17 descends, and the cargo plate 4 on the higher side of the vehicle body 3 is correspondingly lowered.

[0027] The pressure generated after the cargo is loaded on the cargo platform 4 is transmitted to the spindle 20. Through the setting of the movable pulley 21, half of the pressure is transmitted to the winding drum 12 through the pulley cable 24, which reduces the working load of the servo motor 7, making the adjustment of the cargo platform 4 more flexible, enhancing the stability when adjusting the vehicle body 3, and maintaining the stability of the center of gravity of the vehicle body 3.

[0028] The working principle of the present invention is as follows: a pair of cargo plates 4 are used to load goods. The two cargo plates 4 are rotatably connected to the middle of the vehicle body 3. The control component 5 adjusts the angle of the cargo plates 4. When the vehicle body 3 is traveling on an inclined road, the control component 5 uses the cargo plates 4 to adjust the height of the low side and the height of the high side, so that the vehicle body 3 remains balanced and the center of gravity remains stable.

[0029] Because there is an angle between the lower inclined slide block 16 and the upper straight slide block 17, and the cargo plate 4 deflects around the axis, after the cargo plate 4 deflects and moves, the upper straight slide block 17 also forms an angle with the vehicle body 3. The upper slide block 18 and the lower slide block 19 are hinged by the spindle 20. When the power unit drives the spindle 20 to move, the upper slide block 18 and the lower slide block 19 are passively adjusted in angle during sliding, so that the convex locking block is kept sliding in the convex groove. The angle between the cargo plate 4 and the vehicle body 3 is adjusted with the movement of the spindle 20.

[0030] When the vehicle body 3 tilts during driving, hydraulic oil is added to the hydraulic cylinder tilted to the lower side of the hydraulic system. The piston of the hydraulic cylinder pushes outward, and the piston pushes the spindle 20 to move. The spindle 20 drives the lower slide block 19 to slide along the inclined surface of the lower slide block 16. The height of the spindle 20 increases with the increase of the lower slide block 19. The cylinder body of the hydraulic cylinder on the vehicle body 3 adjusts its angle accordingly with the movement of the spindle 20. The upper slide block 18 moves synchronously with the increase of the spindle 20. The upper straight slide block 17 is lifted, and the cargo plate 4 tilted to the lower side of the vehicle body 3 is correspondingly raised. The hydraulic system draws hydraulic oil from the hydraulic cylinder on the higher side, causing the piston of the hydraulic cylinder to retract inward. The spindle 20 drives the lower slider 19 to slide downward along the slope of the lower inclined slide 16. The upper slider 18 moves synchronously as the spindle 20 lowers, and the upper straight slide 17 descends. The cargo plate 4 on the higher side of the vehicle body 3 is lowered accordingly. The hydraulic cylinder is controlled by the signal of the tilt of the vehicle body 3 to deflect the cargo plate 4, adjust the tilt angle of the cargo plate 4 relative to the vehicle body 3, raise the lower side, and adjust the balance and stability of the center of gravity of the vehicle body 3.

[0031] After replacing the hydraulic cylinder with the movable pulley 21, when the vehicle body 3 tilts during driving, the servo motor 7 on the lower side is energized and works. The servo motor 7 drives the drive gear 8 to rotate, and the drive gear 8 drives the synchronous shaft 9 to rotate through the driven gear 10. The synchronous shaft 9 drives the winding device 11 to work. The winding device 11 winds up or releases the pulley cable 24 according to the direction of rotation of the synchronous shaft 9. The synchronous shaft 9 drives the spline shaft 15 to rotate. During the rotation, the spline shaft 15 drives the winding drum 12 to rotate. While rotating, the winding drum 12 drives the threaded ring 13 to rotate. When the threaded ring 13 rotates, the threaded sleeve 14 remains stationary, so that the threaded ring 13 moves while rotating. The winding drum 12 then moves along the axial direction of the spline shaft 15, evenly winding the pulley cable 24 onto the winding drum 12.

[0032] When the winding drum 12 winds up the pulley cable 24, the pulley cable 24 drives the movable pulley 21 to move. The movable pulley 21 slides along the inclined surface of the lower sliding block 16 with the spindle 20. The upper sliding block 18 moves synchronously with the rise of the spindle 20, and the upper straight sliding block 17 is lifted. The cargo plate 4, which is tilted to the lower side of the vehicle body 3, is correspondingly raised. When the winding drum 12 unwinds the pulley cable 24, the weight of the cargo plate 4 is transmitted downward through the upper straight sliding block 17 and the upper sliding block 18 to the lower sliding block 19. After the pulley cable 24 becomes slack, the lower sliding block 19 slides downward along the inclined surface of the lower sliding block 16. The longer the unwound pulley cable 24 is, the more the upper straight sliding block 17 descends, and the cargo plate 4 on the higher side of the vehicle body 3 is correspondingly lowered.

[0033] The pressure generated after the cargo is loaded on the cargo platform 4 is transmitted to the spindle 20. Through the setting of the movable pulley 21, half of the pressure is transmitted to the winding drum 12 through the pulley cable 24, which reduces the working load of the servo motor 7, making the adjustment of the cargo platform 4 more flexible, enhancing the stability when adjusting the vehicle body 3, and maintaining the stability of the center of gravity of the vehicle body 3.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
