Description

Technical Field

[0001] This invention relates to the field of pile hole construction technology, and specifically to a pile hole soil cleaning device. Background Technology

[0002] Construction projects often involve drilling. Taking ground drilling as an example, after the preparation work for drilling is completed, a casing is installed. The casing serves as a reference to fix the position of the pile hole, protect the ground at the hole opening, prevent ground water from flowing in, and guide the drilling direction.

[0003] After the casing is installed, drilling is carried out, and the soil removal is usually done by drilling equipment. However, for small-diameter pile holes, due to economic and site limitations, the soil removal is difficult to complete with mechanical equipment. But if the soil removal is not completed, subsequent work such as the pre-embedding of the reinforcing cage cannot be carried out.

[0004] Therefore, the existing technology uses manual soil removal, but manual operation has the following drawbacks: 1. The construction efficiency is slow and it is time-consuming and labor-intensive; 2. The soil removal depth is limited, and as the soil removal depth increases, the operation difficulty also increases, and the soil removal efficiency also decreases. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the soil cleaning operation of small-diameter pile holes relies on manual labor. The purpose is to provide a pile hole soil cleaning operation device to solve the above-mentioned problem.

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

[0007] A device for cleaning soil from pile holes, comprising:

[0008] The working rod has a cleaning end with spiral blades at its lower end and a driving end at its upper end.

[0009] A drive module, which is connected to the working rod and is used to drive the working rod to lift, lower, or rotate; and

[0010] An auxiliary module, which is connected to the drive module and is used to suspend the drive module above the pile hole.

[0011] In one possible design, the drive module includes a housing, a first drive unit, and a second drive unit;

[0012] The housing is provided with working holes adapted to the working rod and partitions located inside the housing. Correspondingly, the working rod passes through the working holes, and the first drive unit and the second drive unit are respectively arranged on the upper and lower sides of the partition.

[0013] The first drive unit is used to drive the working rod to reciprocate up and down, and the second drive unit is used to drive the working rod to rotate. The first drive unit and the second drive unit work alternately.

[0014] In one possible design, the first drive unit includes a first driver, a turntable, and a drive structure;

[0015] The first driver is installed inside the housing, and the output end of the first driver is connected to the turntable and used to drive the turntable to rotate.

[0016] The turntable is circumferentially aligned with the working rod and is equipped with a drive structure. Several drive structures are provided and are evenly spaced along the circumference of the turntable. Correspondingly, the working rod is equipped with a lifting groove adapted to the drive structure.

[0017] The drive structure includes an inner groove on the turntable, a rotating shaft set in the inner groove, and a drive rod rotatably set on the rotating shaft by a torsion spring. The inner groove is constructed as a one-way through groove that runs through the axial direction of the turntable and has an inner wall along the circumference of the turntable. The upper and lower ends of the drive rod abut against the inner wall of the inner groove, respectively.

[0018] When the working rod rotates, the drive rod rotates out of the inner groove under the action of the working rod. Correspondingly, the lifting groove has an inclined surface set along the circumference of the working rod.

[0019] In one possible design, the second drive unit includes a second driver, a worm gear, a worm wheel, and a control unit;

[0020] The second drive is located inside the housing. The output end of the second drive is connected to the worm gear, which is connected to the worm wheel. The worm wheel is sleeved on the working rod. The control component is located on the partition and is used to control the connection between the worm wheel and the working rod.

[0021] Correspondingly, when the worm gear is connected to the working rod, the second drive unit drives the working rod to rotate, and the control component acts as a transmission key.

[0022] In one possible design, the control components include a control ring and a telescopic rod;

[0023] The control ring is parallel to the worm gear and has an annular surface parallel to the worm gear. A guide rod is provided on the annular surface and passed through the partition. The control ring has an inner circumferential surface that is sleeved on the working rod. The inner circumferential surface of the control ring has a concave annular groove and a rotating ring that is rotatably set on the annular groove. The inner circumferential surface of the rotating ring has a transmission rod that extends along the axial direction of the working rod.

[0024] The telescopic rod is installed on the partition, and the working end of the telescopic rod is connected to the annular surface of the control ring;

[0025] Correspondingly, the worm gear is provided with a concave first rotating groove, the working rod is provided with a concave second rotating groove, and the transmission rod is slidably mounted on the second rotating groove;

[0026] Accordingly, the telescopic rod is used to drive the control ring to rise and fall relative to the worm gear, so that the transmission rod can be inserted into or disengaged from the first rotating slot.

[0027] In one possible design, the control ring is also provided with a third driver and a transmission gear. The output end of the third driver passes through the control ring and is connected to the transmission gear. The transmission gear is rotatably disposed in the control ring and meshes with the outer circumference of the moving ring.

[0028] Correspondingly, the outer periphery of the moving ring is provided with tooth surfaces adapted to the transmission gear;

[0029] Accordingly, the third driver is used to drive the rotating ring to align the first rotating groove with the second rotating groove.

[0030] In one possible design, an additional rod is detachably connected to the upper end of the working rod, which is used to increase the depth to which the working rod enters the pile hole.

[0031] In one possible design, the auxiliary module is selected as an auxiliary frame or an auxiliary vehicle. Both the auxiliary frame and the auxiliary vehicle are equipped with additional modules for lifting and lowering the drive module. Accordingly, when the working rod rotates under the drive of the drive module, the additional module drives the working rod and the drive module to lift and lower synchronously so that the spiral blades are inserted into the soil.

[0032] In one possible design, the auxiliary frame includes two opposing frames and several connecting rods for connecting the two frames;

[0033] A chute with open ends is formed between the two frames, and a connecting rod connects the frames and seals one end of the chute; correspondingly, the drive module is slidably mounted on the frame;

[0034] The additional module is mounted on the frame and can be suspended above the pile hole. The additional module includes a base plate, a fourth driver, a rotating wheel, and a slider. The base plate is fixed on the frame, the fourth driver is mounted on the base plate, the output end of the fourth driver is connected to the rotating wheel, the rotating wheel is mounted on the base plate and connected to the slider via a connecting rod, and the slider is mounted on the base plate and detachably connected to the drive module.

[0035] In one possible design, the auxiliary vehicle is equipped with an auxiliary unit and a robotic arm. The auxiliary unit controls the movement of the robotic arm, which is connected to a drive module. Accordingly, the robotic arm serves as an additional module.

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

[0037] The aforementioned pile hole cleaning device replaces manual labor, making construction faster and more efficient, accelerating construction time, saving construction period, and reducing the workload of workers, effectively solving the problems of time-consuming and labor-intensive manual labor. By increasing the length of the working rod, or by adding an auxiliary rod, the cleaning depth can be increased, without worrying that excessive cleaning will slow down construction efficiency.

Therefore, they should not be construed as limiting the scope of protection of this invention.

[0053] like Figures 1-8 As shown, a pile hole cleaning device includes:

[0054] The working rod 1 has a cleaning end with a spiral blade 101 at its lower end and a driving end at its upper end.

[0055] Drive module 2, which is connected to the working rod 1 and is used to drive the working rod 1 to lift or rotate; and

[0056] An auxiliary module is connected to the drive module 2 and is used to suspend the drive module 2 above the pile hole.

[0057] The soil removal operation for pile holes can be divided into two parts, with the pile hole as the boundary. The first part is the soil removal operation in and above the pile hole, which involves digging out the soil inside the pile hole using tools. The second part is the soil removal operation after the soil removal operation, which involves removing the soil attached to the tools. By repeating the soil removal and soil removal operations, the soil removal operation for the pile hole can be achieved.

[0058] In the described pile hole cleaning device, the soil removal operation is mainly completed through the cooperation of the working rod 1 and the drive module 2. Specifically: after the pile hole cleaning device is erected above the pile hole, the drive module 2 drives the working rod 1 to descend until the spiral blade 101 abuts against the soil inside the pile hole; the drive module 2 then drives the working rod 1 to rotate, and the auxiliary module drives the working rod 1 and drive module 2 to descend as a whole, causing the spiral blade 101 to move down and cut into the soil. In other words, the soil is divided into a part above the spiral blade 101 and a part below the spiral blade 101. The drive module 2 then drives the working rod 1 to rise until the spiral blade 101 and the soil on it move out of the pile hole. Thus, the soil removal operation is completed.

[0059] It is worth noting that the distance the auxiliary module drives downward should be confirmed according to the actual working conditions to ensure that the soil removed by the pile hole cleaning device each time does not exceed the weight limit, so as to improve the service life of the pile hole cleaning device.

[0060] The soil removal operation is completed using an auxiliary module. After the helical blade 101 and the soil on it are moved outside the pile hole, the auxiliary module moves the soil out of the pile hole's projection range. Then, the soil on the helical blade 101 is removed manually and / or with tools. Finally, the helical blade 101 is moved back above the pile hole to facilitate the next soil removal operation.

[0061] The operation of the pile hole cleaning device will be further explained below in conjunction with the structure of each functional module:

[0062] In one possible implementation, the drive module 2 includes a housing 201, a first drive unit 202, and a second drive unit 203;

[0063] The housing 201 is provided with a working hole adapted to the working rod 1 and a partition located inside the housing 201. Correspondingly, the working rod 1 passes through the working hole, and the first drive unit 202 and the second drive unit 203 are respectively arranged on the upper and lower sides of the partition.

[0064] The first drive unit 202 is used to drive the working rod 1 to reciprocate up and down, and the second drive unit 203 is used to drive the working rod 1 to rotate, and the first drive unit 202 and the second drive unit 203 work alternately.

[0065] Based on the above design, the housing 201 provides installation space to integrate the first drive unit 202 and the second drive unit 203, so that the drive module 2 can output two movements, lifting and rotating, to the working rod 1. The first drive unit 202 and the second drive unit 203 work alternately to avoid the two drive units driving the working rod 1 to move at the same time, thereby protecting the drive module 2.

[0066] Meanwhile, the first drive unit 202 and the second drive unit 203 are separated by a partition to avoid mutual interference. In addition, the housing 201 can be constructed in any suitable structure, and the present invention does not impose any restrictions on this.

[0067] For the first drive unit 202, optionally, as Figure 3 As shown, the first drive unit 202 includes a first driver 204, a turntable 205, and a drive structure;

[0068] The first driver 204 is disposed inside the housing 201. The output end of the first driver 204 is connected to the turntable 205 and is used to drive the turntable 205 to rotate.

[0069] The turntable 205 is circumferentially aligned with the working rod 1 and is equipped with a drive structure. The drive structure has several units that are equally spaced along the circumference of the turntable 205. Correspondingly, the working rod 1 is equipped with a lifting groove 102 adapted to the drive structure.

[0070] The drive structure includes an inner groove on the turntable 205, a rotating shaft 206 disposed in the inner groove, and a drive rod 207 rotatably disposed on the rotating shaft 206 by a torsion spring. The inner groove is constructed as a one-way through groove that runs through the axial direction of the turntable 205 and has an inner wall along the circumference of the turntable 205. The upper and lower ends of the drive rod 207 respectively abut against the inner wall of the inner groove.

[0071] When the working rod 1 rotates, the drive rod 207 rotates out of the inner groove under the drive of the working rod 1. Correspondingly, the lifting groove 102 has an inclined surface arranged along the circumference of the working rod 1.

[0072] Based on the above design, the power of the first driver 204 is transmitted to the drive structure via the turntable 205. The drive structure is connected to the working rod 1 and drives the working rod 1 to rise and fall. In the drive structure, at least one drive rod 207 is inserted into the lifting groove 102 on the working rod 1. The drive rod 207 rotates with the turntable 205 and drives the working rod 1 to rise and fall.

[0073] Accordingly, several lifting slots 102 are provided and are equally spaced along the axial direction of the working rod 1 to facilitate the first drive unit 202 to drive the entire working rod 1 to rise and fall. The height of each lifting slot 102 is greater than the height of the drive rod 207, so that the drive rod 207 can be more easily inserted into the lifting slot 102. Therefore, when the working rod 1 rises, one of the drive rods 207 is inserted into one of the lifting slots 102, the drive rod 207 abuts against the upper wall of the lifting slot 102 and drives the working rod 1 to rise; when the working rod 1 falls, one of the drive rods 207 is inserted into one of the lifting slots 102, the drive rod 207 abuts against the upper wall of the lifting slot 102 and controls the speed of the falling working rod 1.

[0074] Meanwhile, since the working rod 1 also rotates under the action of the second drive unit 203, in the drive structure, the drive rod 207 is rotatably mounted on the rotating shaft 206 via a torsion spring, allowing the drive rod 207 to rotate. The inner groove extends axially along the turntable 205, and the lifting groove 102 has an inclined surface arranged circumferentially along the working rod 1. The former provides rotation space for the drive rod 207 (i.e., the drive rod 207 can rotate outside the turntable 205), while the latter uses the rotation of the working rod 1 as power to drive the drive rod 207 to rotate. Based on this, when the working rod 1 rotates, the drive rod 207 can rotate along the inclined surface of the lifting groove 102 to avoid obstructing the rotation of the working rod 1. When the working rod 1 stops rotating, and when the lifting groove 102 is directly opposite the turntable 205, the drive rod 207 resets under the action of the torsion spring and inserts into the lifting groove 102.

[0075] In addition, the upper and lower ends of the drive rod 207 abut against the inner wall of the groove to reduce unexpected disturbances to the drive rod 207 during transmission and improve transmission efficiency.

[0076] For the second drive unit 203, optionally, as Figures 3-6 As shown, the second drive unit 203 includes a second driver, a worm gear 208, a worm wheel 209, and a control unit 210;

[0077] The second driver is installed inside the housing 201. The output end of the second driver is connected to the worm 208. The worm 208 is connected to the worm wheel 209. The worm wheel 209 is sleeved on the working rod 1. The control component 210 is installed on the partition and is used to control the connection between the worm wheel 209 and the working rod 1.

[0078] Accordingly, when the worm gear 209 is connected to the working rod 1, the second drive unit 203 drives the working rod 1 to rotate, and the control element 210 is used as a transmission key.

[0079] Based on the above design, a worm gear structure is used to transmit power and change the direction of the force to drive the working rod 1 to rotate. Simultaneously, a control unit 210 controls the connection relationship. When the control unit 210 connects the worm gear 209 and the working rod 1, the power of the second drive can be transmitted to the working rod 1 to make it rotate. At this time, the drive rod 207 in the first drive unit 202 will rotate outside the turntable 205. Conversely, when the control unit 210 disconnects the worm gear 209 from the working rod 1, the power of the second drive cannot be transmitted to the working rod 1, meaning the working rod 1 will rise and fall under the drive of the first drive unit 202. In this case, the working rod 1 should rotate in advance until its lifting slot 102 is directly opposite the turntable 205, and then the control unit 210 disconnects the connection.

[0080] Optionally, such as Figures 3-6 As shown, the control component 210 includes a control ring 211 and a telescopic rod 212;

[0081] The control ring 211 is parallel to the worm gear 209 and has an annular surface parallel to the worm gear 209. A guide rod 213 passing through the partition is provided on the annular surface. The control ring 211 has an inner circumferential surface that is sleeved on the working rod 1. The inner circumferential surface of the control ring 211 is provided with a concave annular groove and a rotating ring 214 rotatably disposed on the annular groove. A transmission rod 215 extending along the axial direction of the working rod 1 is provided on the inner circumferential surface of the rotating ring 214.

[0082] The telescopic rod 212 is installed on the partition, and the working end of the telescopic rod 212 is connected to the annular surface of the control ring 211;

[0083] Correspondingly, the worm gear 209 is provided with a concave first rotating groove 216, the working rod 1 is provided with a concave second rotating groove 103, and the transmission rod 215 is slidably disposed on the second rotating groove 103;

[0084] Accordingly, the telescopic rod 212 is used to drive the control ring 211 to rise and fall relative to the worm gear 209, so that the transmission rod 215 can be inserted into or disengaged from the first rotating slot 216.

[0085] Based on the above design, the telescopic rod 212 drives the control ring 211 to rise and fall. When the control ring 211 approaches the worm gear 209, the transmission rod 215 slides along the second rotating groove 103 and inserts into the first rotating groove 216, thus connecting the worm gear 209 with the working rod 1. At this time, the control component 210 acts as a transmission key. Conversely, when the control ring 211 moves away from the worm gear 209, the transmission rod 215 slides along the second rotating groove 103 and disengages from the first rotating groove 216, thus releasing the connection between the worm gear 209 and the working rod 1.

[0086] Meanwhile, the guide rod 213 passes through the partition plate. The guide rod 213 and the partition plate work together to guide the lifting and lowering direction of the control ring 211, ensuring that the control ring 211 lifts and lowers synchronously as a whole.

[0087] It is worth noting that when the worm gear 209 is connected to the working rod 1 through the control component 210, that is, when the working rod 1 can rotate, the control ring 211 will remain relatively stationary, while the moving ring 214 and the transmission rod 215 rotate synchronously while transmitting the force, so as to avoid other parts of the control component 210 from preventing the rotation of the working rod 1.

[0088] Preferably, such as Figure 3 and Figure 4 As shown, the worm gear 209 is disposed above the partition (i.e., the second drive unit 203 is disposed above the partition, and the first drive unit 202 is disposed below the partition), and the partition is provided with a bracket 219 for supporting the worm gear 209. The worm gear 209 is suspended above the partition to reduce the contact area between the worm gear 209 and the partition, and a contact surface with a low coefficient of friction is provided between the bracket 219 and the worm gear 209 to reduce the wear of the worm gear 209 during rotation.

[0089] Correspondingly, the control component 210 can be positioned above the partition and offset from the bracket 219, or the control component 210 can be positioned below the partition. The former helps to shorten the distance between the control component 210 and the worm gear 209, but the local structure is too complex. The latter structure is simpler, but the distance between the control component 210 and the worm gear 209 increases, and the dimensions of the control component 210, such as the length of the transmission rod 215 and the lifting height of the telescopic rod 212, will also increase to a certain extent.

[0090] Optionally, such as Figure 6 As shown, the control ring 211 is also provided with a third driver 217 and a transmission gear 218. The output end of the third driver 217 passes through the control ring 211 and is connected to the transmission gear 218. The transmission gear 218 is rotatably disposed in the control ring 211 and meshes with the outer periphery of the moving ring 214.

[0091] Correspondingly, the outer periphery of the moving ring 214 is provided with tooth surfaces adapted to the transmission gear 218;

[0092] Accordingly, the third driver 217 is used to drive the rotating ring 214 to rotate so that the first rotating groove 216 is aligned with the second rotating groove 103.

[0093] Based on the above design, when the pile hole cleaning device experiences unexpected disturbance, the working rod 1 rotates, causing the first rotating groove 216 and the second rotating groove 103 to misalign. In this case, the transmission rod 215 cannot be inserted into the first rotating groove 216. To address this, the control ring 211 is equipped with a third driver 217 and a transmission gear 218. The third driver 217 drives the transmission gear 218 to rotate, which in turn drives the rotating ring 214 to rotate. Since the rotating ring 214 is always inserted into the second rotating groove 103, the working rod 1 rotates until the first rotating groove 216 and the second rotating groove 103 are aligned.

[0094] As is easily understood, the housing 201 is equipped with a sensor for detecting whether the first rotating groove 216 and the second rotating groove 103 are aligned. The sensor is electrically connected to the third driver 217. Before the working rod 1 rotates, the sensor detects whether the first rotating groove 216 and the second rotating groove 103 are aligned, thereby determining whether the third driver 217 is started.

[0095] It is easy to understand that the control component 210 has at least one transmission rod 215, and generally, it is preferred to have multiple transmission rods 215. Correspondingly, the worm gear 209 has multiple first rotating grooves 216, and the working rod 1 has multiple second rotating grooves 103, and the transmission rod 215, the first rotating grooves 216 and the second rotating grooves 103 are arranged in a one-to-one correspondence.

[0096] For working lever 1, such as Figure 7 As shown, it is provided with a plurality of lifting grooves 102 arranged at equal intervals along the axial direction, and at least one second rotating groove 103 extending and penetrating along the axial direction. Correspondingly, the lifting grooves 102 and the second rotating grooves 103 are staggered from each other.

[0097] Furthermore, preferably, an additional rod is detachably connected to the upper end of the working rod 1. The additional rod is used to increase the depth to which the working rod 1 enters the pile hole. Based on this, the additional rod is also the working rod 1 without the helical blade 101, and the two are connected by any suitable existing detachable connection method. It is easy to understand that if the pile hole depth is too deep, multiple additional rods can be set, and adjacent additional rods can also be detached and connected to ensure the completion of the soil clearing operation.

[0098] In one possible implementation, the auxiliary module is selected as auxiliary frame 3 or auxiliary vehicle 4. Both auxiliary frame 3 and auxiliary vehicle 4 are equipped with additional modules for driving module 2 to lift and lower. Accordingly, when the working rod 1 rotates under the drive of the drive module 2, the additional module drives the working rod 1 and the drive module 2 to lift and lower synchronously so that the spiral blade 101 is screwed into the soil.

[0099] Based on the above design scheme, the auxiliary frame 3 can be any suitable frame structure, which is simple and lower in cost, but requires workers to perform auxiliary operations to enable the pile hole cleaning device to complete the cleaning operation. The auxiliary vehicle 4 has more comprehensive functions and helps to realize automated operation, but it is more expensive. Therefore, workers can choose according to the actual working conditions.

[0100] Furthermore, the downward movement of the auxiliary module driving rod 1 and driving module 2 during soil extraction is accomplished through an additional module. The structures of the additional modules on the auxiliary frame 3 and auxiliary vehicle 4 differ, specifically:

[0101] In one possible implementation, the auxiliary frame 3 includes two opposing frames 301 and a plurality of connecting rods 302 for connecting the two frames 301.

[0102] A sliding groove with open ends is formed between the two frames 301, and the connecting rod 302 connects the frames 301 and seals one end of the sliding groove; correspondingly, the drive module 2 is slidably mounted on the frame 301;

[0103] The additional module is mounted on the frame 301 and can be suspended above the pile hole. The additional module includes a base plate 303, a fourth driver 304, a rotating wheel 305, and a slider 306. The base plate 303 is fixed on the frame 301. The fourth driver 304 is mounted on the base plate 303. The output end of the fourth driver 304 is connected to the rotating wheel 305. The rotating wheel 305 is rotatably mounted on the base plate 303 and connected to the slider 306 through a connecting rod 307. The slider 306 is slidably mounted on the base plate 303 and is detachably connected to the drive module 2.

[0104] Based on the above design, the additional module is constructed as a slider reciprocating mechanism. Specifically, the fourth driver 304 drives the rotating wheel 305 to rotate. The rotating wheel 305 is connected via a connecting rod 307 and drives the slider 306 to reciprocate. When the slider 306 slides downwards, the working rod 1 and the driving module 2 move downwards as a whole, causing the spiral blade 101 to move downwards and cut into the soil. Conversely, when the slider 306 moves upwards, the working rod 1 and the driving module 2 move upwards and reset, simultaneously separating the two parts of the soil.

[0105] When the soil dumping operation is carried out, the workers pull the drive module 2 to move it towards the open end of the chute so that the spiral blade 101 is misaligned with the pile hole. Then the workers can remove the soil from the spiral blade 101.

[0106] Regarding the connection between slider 306 and drive module 2, slider 306 has a recessed first connecting groove, and the housing 201 of drive module 2 has a protruding retaining strip. One end of the first connecting groove is open. When the retaining strip is inserted into the connecting groove from the open end, the connection between slider 306 and drive module 2 is achieved. Conversely, when slider 306 is disengaged from drive module 2, drive module 2 can move along the chute and away from the pile hole to facilitate soil dumping operations.

[0107] Correspondingly, a second connecting groove is provided on the frame 301. When the slider 306 moves up and resets, the first connecting groove and the second connecting groove are connected so that the drive module 2 can slide along the frame 301.

[0108] In one possible implementation, the auxiliary vehicle 4 is equipped with an auxiliary unit 401 and a robotic arm 402. The auxiliary unit 401 is used to control the movement of the robotic arm 402. The robotic arm 402 is connected to the drive module 2. Accordingly, the robotic arm 402 is used as an additional module.

[0109] Based on the above design, the auxiliary unit 401 is used to realize functions such as control and power supply. The auxiliary unit 401 can be composed of any suitable existing equipment. The robotic arm 402 has multi-degree-of-freedom movement function to facilitate various movements, thereby realizing soil removal operations, soil dumping operations, etc., and realizing automated operations; it is easy to understand that the robotic arm 402 can also be any suitable existing model.

[0110] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. 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.
