Description

Technical Field

[0001] The invention belongs to the technical field of bolt loosening detection, and in particular relates to a device and method for quickly detecting bolt loosening of a transmission tower. Background Art

[0002] Transmission towers are composed of several frames and are used to transmit electricity. The frames are generally fixed by bolts. Loose bolts will seriously affect the safety of power transmission and even cause the tower to collapse in serious cases. There are two main ways to detect bolt loosening: shaking detection and spacing detection. The shaking detection directly shakes the bolts. When the bolts are loose, a gap is generated between the bolt head and the frame. If the bolt head shakes, it means that the bolt is loose. The spacing detection measures the distance between the nut and the bolt head. When the bolt is loose, the nut moves along the bolt to the side away from the bolt head. If the distance between the nut and the bolt head increases, it means that the bolt is loose. Although the shaking detection is fast, it is affected by factors such as the thickness of the tower frame, which makes it difficult for some bolts to shake after they are loose, and the reliability is insufficient. Although the results of the spacing detection are more reliable, the bolts and nuts need to be clamped and loosened frequently, resulting in a slow speed and insufficient efficiency.

[0003] When in use, the existing transmission tower bolt loosening detection device generally only has a shaking detection method or a spacing detection method. It is difficult to balance speed and reliability when using only one detection method to detect bolt loosening. Switching one detection method requires switching another detection device, resulting in insufficient applicability. In addition, traditional detection devices usually use distance sensors, torque sensors and other components that require electricity to maintain operation to detect bolt loosening. It is difficult to detect in the case of insufficient power or power outages, and the reliability is insufficient. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a transmission tower bolt loosening rapid detection device and method, which can first quickly perform shaking detection on the bolts through a shaking clamping mechanism, and can further perform spacing detection on the bolts through a spacing clamping mechanism and a spacing prompting mechanism, so that the two detection methods are combined to balance speed and reliability, and improve the efficiency of bolt loosening detection.

[0020] The method for using the transmission tower bolt loosening rapid detection device is applicable to the above-mentioned transmission tower bolt loosening rapid detection device. The specific method of use is as follows:

[0021] S1: First, adjust the distance between the first clamping plate and the second clamping plate by rotating the double-headed positive and negative threaded screw, so that the spacing between the first clamping plate and the second clamping plate matches the head size of the bolt, and adjust the distance between the third clamping plate and the second mounting plate by rotating the movable handle, so that the spacing between the third clamping plate and the second mounting plate is equal to the distance between the unloosened bolt and the nut. At this time, adjust the height position of the first slider by rotating the vertical lead screw, so that when the lifting plate abuts against the second slider, the pointer is away from one end of the second slider, the scale on the second scale line in the horizontal direction and the appropriate scale on the third scale line in the vertical direction are located in the same horizontal plane;

[0022] S2: Perform shaking detection, move the first clamping plate and the second clamping plate towards the direction close to the bolt head, so that the first clamping plate and the second clamping plate clamp the bolt head, shake the first clamping plate and the second clamping plate, if the first clamping plate and the second clamping plate drive the bolt head to shake, a gap will appear between the bolt head and the tower, indicating that the bolt is loose;

[0023] S3: If the bolt head does not shake, perform a spacing test, move the second mounting plate upward so that the lower end of the bolt head fits against the top of the second mounting plate, turn the movable handle, and the movable handle drives the third clamping plate to move downward through the connecting rod and the lifting block, so that the third clamping plate and the second mounting plate clamp the nut and the bolt. In this process, the lifting block drives the second slider to slide downward through the lifting plate to cause a displacement in the vertical direction, and the second slider drives the end of the pointer away from the second slider to rotate synchronously upward along the second scale line to cause angular displacement. If the end of the pointer away from the second slider does not rotate to the scale on the second scale line in the horizontal direction, the distance between the nut and the bolt head increases to indicate that the bolt is loose, otherwise the bolt is not loose.

[0024] The technical effects achieved by the present invention are:

[0025] The present invention adopts the design of a shaking clamping mechanism, which can first quickly perform shaking detection on the bolt. When the detection starts, the bolt head is first clamped by the first clamping plate and the second clamping plate and shaken. If the bolt head shakes, the bolt is loose, thereby compensating for the deficiency of the spacing detection in detection speed and improving the efficiency of bolt loosening detection.

[0026] The present invention adopts the design of a spacing clamping mechanism and a spacing prompting mechanism, which can further perform spacing detection on the bolts. If the bolt head does not shake during the shaking detection, the movable handle is rotated to make the third clamping plate move downward close to the nut, and the pointer rotates clockwise along the second scale line under the drive of the lifting plate, and the displacement of the third clamping plate in the vertical direction is magnified and displayed as the angular displacement of the pointer. When the third clamping plate and the second mounting plate clamp the nut and the bolt, if the pointer does not rotate to the scale on the second scale line in the horizontal direction, it indicates that the bolt is loose, otherwise the bolt is not loose, thereby making up for the lack of reliability of the shaking detection and improving the efficiency of bolt loosening detection.

[0027] The present invention adopts the design of a shaking type clamping mechanism, a spacing type clamping mechanism and a spacing type prompting mechanism. The shaking type clamping mechanism, the spacing type clamping mechanism and the spacing type prompting mechanism do not require electricity to maintain their operation, thereby avoiding the situation where it is difficult to detect the looseness of the bolts through components that require electricity to maintain their operation in the case of insufficient power or power outage, thereby improving the reliability of bolt detection.

[0042] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0043] Example 1

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, it is the first embodiment of the present invention, which provides a transmission tower bolt loosening rapid detection device and method, including a first mounting plate 10, the bottom of the first mounting plate 10 is fixedly connected to a second mounting plate 11; a shaking clamping mechanism 20, the shaking clamping mechanism 20 is slidably mounted on the second mounting plate 11, and is used to clamp the bolt head in the horizontal direction; a spacing clamping mechanism 30, the spacing clamping mechanism 30 is slidably mounted on the first mounting plate 10, and is used to clamp the bolt and nut in the vertical direction; a spacing prompting mechanism 40, the spacing prompting mechanism 40 is rotatably mounted on one side of the spacing clamping mechanism 30, and is used to enlarge and display the sliding distance of the spacing clamping mechanism 30.

[0045] It should be noted that when detecting bolt looseness, the bolt is inserted into the inside of the two frames, and the bolt head is located below the frame. A gasket and two nuts are arranged on the top of the frame from bottom to top, and the nuts are threadedly connected to the bolts.

[0046] When the present invention is in use, the bolt head is placed in the shaking clamping mechanism 20, and the bolt is subjected to shaking detection by shaking the shaking clamping mechanism 20. If the bolt head shakes, it indicates that a gap appears between the bolt head and the tower frame, thereby prompting that the bolt is loose. Otherwise, a spacing detection is performed. After the spacing clamping mechanism 30 is actuated, it clamps the nut and the bolt together with the second mounting plate 11 to measure the distance between the nut and the bolt head. The spacing prompting mechanism 40 prompts whether the current spacing between the nut and the bolt head is greater than the spacing between the nut and the bolt head when not loose. If greater, it indicates that the nut moves toward the side away from the bolt head, indicating that the bolt is loose. Otherwise, the bolt is not loose. Thus, the shaking detection is combined with the spacing detection, and the efficiency of bolt loosening detection is improved. The shaking clamping mechanism 20, the spacing clamping mechanism 30 and the spacing prompting mechanism 40 do not require electricity to maintain operation, thereby improving the reliability of bolt detection.

[0047] Example 2

[0048] Reference Figures 1 to 9 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0049] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the rocking clamping mechanism 20 includes a double-headed forward and reverse threaded screw 201 rotatably connected to the upper end of the second mounting plate 11, one end of the double-headed forward and reverse threaded screw 201 is threadedly connected to a first clamping plate 202, and the other end of the double-headed forward and reverse threaded screw 201 is threadedly connected to a second clamping plate 203, the first clamping plate 202 and the second clamping plate 203 have opposite thread rotation directions, and the first clamping plate 202 and the second clamping plate 203 are both slidably connected to the second mounting plate 11.

[0050] It should be noted that both ends of the double-ended forward and reverse threaded screw 201 are provided with threads with opposite rotation directions, and one end of the double-ended forward and reverse threaded screw 201 is fixedly connected to a knob, so that the user can rotate the double-ended forward and reverse threaded screw 201 through the knob.

[0051] According to the above structure, when it is necessary to perform a shaking detection on the bolt head, the double-headed positive and negative threaded screw 201 is rotated to make the first clamping plate 202 and the second clamping plate 203 slide inward or outward along the second mounting plate 11, thereby adjusting the distance between the first clamping plate 202 and the second clamping plate 203, which is convenient for clamping bolt heads of different sizes and improving applicability. The bolt head is driven to shake by rotating the first clamping plate 202 and the second clamping plate 203. If the bolt head shakes, it indicates that there is a gap between the bolt head and the frame, and the bolt is loose, thereby facilitating a shaking detection of the bolt head.

[0052] like Figure 4 As shown, guide rods 204 are slidably disposed inside the first clamping plate 202 and the second clamping plate 203 , and the guide rods 204 are fixedly connected to the second mounting plate 11 .

[0053] It should be noted that there are two guide rods 204 , and the axis of the guide rod 204 is parallel to the axis of the double-headed positive and negative thread screw 201 .

[0054] According to the above structure, the guide rod 204 is slidably connected to the first clamping plate 202, so that the sliding process of the first clamping plate 202 along the second mounting plate 11 is more stable, and the guide rod 204 is slidably connected to the second clamping plate 203, so that the sliding process of the second clamping plate 203 along the second mounting plate 11 is more stable.

[0055] like Figure 4 As shown, a first scale line 205 is provided at one end of the second mounting plate 11 , and the first scale line 205 is parallel to the axis of the double-headed positive and negative threaded screw 201 .

[0056] It should be noted that the first scale line 205 is disposed at the opening of the first clamping plate 202 and the second clamping plate 203 .

[0057] According to the above structure, when it is necessary to adjust the distance between the first clamp plate 202 and the second clamp plate 203 to adapt to bolt heads of different sizes, the first scale line 205 facilitates the user to observe the changes in the distance between the first clamp plate 202 and the second clamp plate 203 during the adjustment process, thereby facilitating the adjustment of the distance between the first clamp plate 202 and the second clamp plate 203.

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the spacing clamping mechanism 30 includes a lifting block 301 slidably mounted on the first mounting plate 10, one side of the lifting block 301 is fixedly connected to a third clamping plate 302, the other side of the lifting block 301 is fixedly connected to a connecting rod 303, the lower end of the connecting rod 303 is slidably connected to a movable handle 304, and the movable handle 304 is rotatably mounted on the first mounting plate 10.

[0059] It should be noted that a slide rail is installed between the spacing clamping mechanism 30 and the first mounting plate 10, the third clamping plate 302 is located on one side of the first mounting plate 10, and the connecting rod 303 is located on the other side of the first mounting plate 10. A slot is provided at one end of the third clamping plate 302 away from the first mounting plate 10, and the inner diameter of the slot is larger than the diameter of the bolt and smaller than the outer diameter of the nut. A first sliding column is fixedly connected to the bottom of the connecting rod 303, and a first sliding hole is provided at one end of the movable handle 304 close to the connecting rod 303. The first sliding column and the first sliding hole are slidably matched, and the first sliding column and the first sliding hole are rotatably matched.

[0060] According to the above structure, when performing spacing detection, it is necessary to clamp the nuts and bolts, and rotate the movable handle 304 so that the movable handle 304 drives the connecting rod 303 to move downward, and the connecting rod 303 drives the third clamping plate 302 to move downward through the lifting block 301, thereby reducing the distance between the third clamping plate 302 and the second mounting plate 11. During this process, the bottom of the third clamping plate 302 gradually approaches the top of the nut, so that the nuts and bolts are clamped by the third clamping plate 302 and the second mounting plate 11, which is convenient for spacing detection.

[0061] like Figure 5 and Figure 6 As shown, the movable handle 304 is rotatably connected to the outside with a fixed handle 305 , the fixed handle 305 is fixedly connected to the first mounting plate 10 , and a spring 306 is fixedly connected between the fixed handle 305 and the movable handle 304 .

[0062] It should be noted that the movable handle 304 and the first mounting plate 10 are rotatably mounted together via the fixed handle 305 .

[0063] According to the above structure, when it is necessary to clamp the nuts and bolts, the movable handle 304 is rotated, and the end of the movable handle 304 close to the fixed handle 305 is rotated upward, so that the distance between the movable handle 304 and the fixed handle 305 is reduced. At this time, the spring 306 is compressed and the height is reduced. When it is not necessary to clamp the nuts and bolts, the movable handle 304 is no longer rotated, and the spring 306 restores its height to push the end of the movable handle 304 close to the fixed handle 305 to move downward. The movable handle 304 drives the connecting rod 303 to move upward, and the connecting rod 303 drives the third clamping plate 302 to move upward through the lifting block 301, thereby releasing the clamping of the nuts and bolts. In this process, the fixed handle 305 is convenient for the user to rotate and hold the movable handle 304 by hand, and the spring 306 facilitates the resetting of the movable handle 304.

[0064] like Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the spacing prompt mechanism 40 includes a vertical screw 401 rotatably connected to the first mounting plate 10, one end of the vertical screw 401 is sleeved with a screw anti-rotation fixing member 402, the screw anti-rotation fixing member 402 is fixedly installed on the first mounting plate 10, the external thread of the vertical screw 401 is connected with a first slider 403, the first slider 403 is slidably connected to the first mounting plate 10, one side of the first slider 403 is rotatably connected with a pointer 404, a torsion spring 405 is fixedly connected between the pointer 404 and the first slider 403, one end of the pointer 404 is slidably connected with a second slider 406, a lifting plate 407 is provided above the second slider 406, the lifting plate 407 is fixedly connected to the lifting block 301, a first scale plate 408 is provided at one end of the pointer 404 away from the second slider 406, the first scale plate 408 is fixedly connected to the first slider 403, and a second scale line 4081 is provided on the first scale plate 408 along the circumference of the rotation center of the pointer 404.

[0065] It should be noted that the screw anti-rotation fixing member 402 includes a clamping body sleeved on the upper end of the vertical screw 401, the clamping body is fixedly installed on the first mounting plate 10, one side of the clamping body is fixedly connected to a tensioning part, the interior of the tensioning part is provided with a tensioning groove, the interior of the tensioning part is penetrated by a limit screw, one side of the tensioning part is provided with a limit nut, the limit nut is threadedly connected to the limit screw, after the limit nut is rotated, the gap in the tensioning groove is reduced, so that the clamping body clamps the vertical screw 401, limits the vertical screw 401 and the first mounting plate 10, the upper end of the vertical screw 401 is fixedly connected to a turning handle, so that the user can rotate the vertical screw 401 through the turning handle, and the inner part of the first slider 403 A second slide groove 4032 is provided on the second slider 406, and a second slide bar 4061 is fixedly connected to the second slider 406. The second slide bar 4061 slidably cooperates with the second slide groove 4032, and the second slide bar 4061 cooperates with the second slide groove 4032, so that the movement of the second slider 406 along the first slider 403 is more stable. In the initial state, the end of the pointer 404 away from the second slider 406 is located below the horizontal scale on the second scale line 4081, and a second slide column is fixedly connected to the second slider 406. A second slide hole is provided on the end of the pointer 404 close to the second slider 406, and the second slide column slidably cooperates with the second slide hole, and the second slide column and the second slide hole rotatably cooperate.

[0066] According to the above structure, when it is necessary to magnify the displacement of the nut moving toward the side away from the bolt head, before detecting the bolt, the movable handle 304 is first rotated, and the movable handle 304 drives the lifting block 301 and the third clamping plate 302 to move up and down through the connecting rod 303, so that the distance between the third clamping plate 302 and the second mounting plate 11 is equal to the distance between the nut and the bolt head when the bolt is not loose. At this time, the vertical lead screw 401 is rotated to make the first slider 403 slide up and down in the vertical direction, and the first slider 403 drives the pointer 404 and the first The scale plate 408 slides up and down, and the lifting plate 407 remains fixed at a height position under the limit of the lifting block 301. The lifting plate 407 prevents the second slider 406 from sliding upward, so that the second slider 406 drives the pointer 404 to rotate along the second scale line 4081. When the pointer 404 rotates to a horizontal state, the end of the pointer 404 away from the second slider 406 coincides with the scale on the second scale line 4081 in the horizontal direction, and the vertical lead screw 401 is limited by the lead screw anti-rotation fixing member 402, so that the first slider 403 and the first scale line 4081 are aligned. The height position of the scale plate 408 remains fixed. At this time, the scale along the horizontal direction on the second scale line 4081 indicates that the bolt is not loose. When the bolt is tested in spacing mode, the lifting block 301 drives the third clamping plate 302 to move downward while also driving the lifting plate 407 to move downward. The lifting plate 407 pushes the second slider 406 downward, so that the second slider 406 slides downward along the first slider 403. The second slider 406 drives the pointer 404 to rotate clockwise, so that the end of the pointer 404 away from the second slider 406 moves along the second scale line. Line 4081 rotates upward. If the pointer 404 does not rotate to the horizontal scale position on the second scale line 4081, it means that the current distance between the nut and the bolt head is greater than the distance between the nut and the bolt head when the bolt is not loose, and the bolt is loose. In this process, the spacing prompt mechanism 40 amplifies the displacement of the third clamping plate 302 in the vertical direction and displays it as the angular displacement of the pointer 404 sweeping across the second scale line 4081, which is convenient for the user to observe the change in the distance between the nut and the bolt head, thereby facilitating the spacing detection of the bolts.

[0067] like Figure 2 and Figure 7 As shown, a second scale plate 409 is disposed on the outer side of the first scale plate 408 , the second scale plate 409 is fixedly connected to the first mounting plate 10 , and a third scale line 4091 is disposed on the second scale plate 409 along the vertical direction.

[0068] It should be noted that the third scale line 4091 is coplanar with the second scale line 4081 .

[0069] According to the above structure, when adjusting the height position of the first scale plate 408, the scale along the horizontal direction on the second scale line 4081 is aligned with the scale at the appropriate height position of the third scale line 4091, so that the user can intuitively adjust the height position of the first scale plate 408.

[0070] like Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, a first sliding groove 4031 is provided inside the first sliding block 403 , a first sliding bar 101 is fixedly connected to the first mounting plate 10 , and the first sliding bar 101 is slidably matched with the first sliding groove 4031 .

[0071] It should be noted that the shapes of the first sliding bar 101 and the first sliding groove 4031 are both dovetail-shaped or T-shaped.

[0072] According to the above structure, the first slide bar 101 cooperates with the first slide groove 4031 , so that the first slider 403 slides along the first mounting plate 10 more stably.

[0073] In order to enable those skilled in the art to have a further understanding of the transmission tower bolt loosening rapid detection device of the present invention, the present invention also provides a method for using the transmission tower bolt loosening rapid detection device, which is applicable to the above-mentioned transmission tower bolt loosening rapid detection device, and the specific method of use is:

[0074] S1: First, the distance between the first clamping plate 202 and the second clamping plate 203 is adjusted by rotating the double-headed positive and negative threaded screw 201, so that the distance between the first clamping plate 202 and the second clamping plate 203 is adapted to the head size of the bolt, and the distance between the third clamping plate 302 and the second mounting plate 11 is adjusted by rotating the movable handle 304, so that the distance between the third clamping plate 302 and the second mounting plate 11 is equal to the distance between the unloosened bolt and nut. At this time, the height position of the first slider 403 is adjusted by rotating the vertical lead screw 401, so that when the lifting plate 407 abuts against the second slider 406, the end of the pointer 404 away from the second slider 406, the scale on the second scale line 4081 along the horizontal direction and the appropriate scale on the third scale line 4091 along the vertical direction are located in the same horizontal plane;

[0075] S2: Perform shaking detection, move the first clamping plate 202 and the second clamping plate 203 toward the direction close to the bolt head, so that the first clamping plate 202 and the second clamping plate 203 clamp the bolt head, shake the first clamping plate 202 and the second clamping plate 203, if the first clamping plate 202 and the second clamping plate 203 drive the bolt head to shake, a gap will appear between the bolt head and the tower, indicating that the bolt is loose;

[0076] S3: If the bolt head does not shake, a spacing detection is performed, the second mounting plate 11 is moved upward so that the lower end of the bolt head is fitted with the top of the second mounting plate 11, and the movable handle 304 is turned. The movable handle 304 drives the third clamping plate 302 to move downward through the connecting rod 303 and the lifting block 301, so that the third clamping plate 302 and the second mounting plate 11 clamp the nut and the bolt. In this process, the lifting block 301 drives the second slider 406 to slide downward through the lifting plate 407 to cause displacement in the vertical direction, and the second slider 406 drives the end of the pointer 404 away from the second slider 406 to rotate upward along the second scale line 4081 synchronously to cause angular displacement. If the end of the pointer 404 away from the second slider 406 does not rotate to the horizontal scale on the second scale line 4081, the distance between the nut and the bolt head increases to indicate that the bolt is loose, otherwise the bolt is not loose.

[0077] Example 3

[0078] The difference between Example 3 and Example 2 lies in the difference of the third clamping plate 302, specifically:

[0079] The notch of the third clamping plate 302 is set to be adjustable. The specific adjustment structure of the notch is a spanner structure (not shown in the figure), and the opening width can be adjusted within a certain range.

[0080] In an embodiment, when an operator detects that a bolt is loose, the detection device can be used to directly tighten it. Specifically, since a gasket is generally provided at the head of the bolt or the tail of the nut when the bolt is fixed, in actual operation, although the nut is loose, when tightening, the bolt or nut alone can be used to tighten the bolt. Specifically, the tightening method can be selected according to the type of bolt.

[0081] The method for fixing the nut is to first release the limit on the bolt head by the rocking clamping mechanism 20, adjust the notch of the third clamping plate 302 to be larger than the nut specification, rotate the movable handle 304 to make the notch reach the position corresponding to the nut, fine-tune the entire device, change the notch opening width to clamp the nut, and rotate the device in the tightening direction to tighten it.

[0082] The method for fixing the bolt by tightening is to make the swing-type clamping mechanism 20 keep locking the bolt, and then rotate the device in the tightening direction to tighten it.

[0083] Based on this, the device can not only achieve normal detection effects, but also can tighten bolts and nuts of different specifications after they are loosened, and has a wider applicability.

[0084] The working principle of the present invention is as follows: when it is necessary to detect the looseness of the bolt, firstly, a shaking detection is performed, the shaking clamping mechanism 20 is matched with the bolt head, and the shaking clamping mechanism 20 is shaken. If the shaking clamping mechanism 20 drives the bolt head to shake, the bolt is loose. If the bolt head does not shake, a spacing detection is performed. After the spacing clamping mechanism 30 is actuated, it clamps the nut and the bolt together with the second mounting plate 11. The spacing prompting mechanism 40 prompts whether the spacing between the current nut and the bolt head is greater than the spacing between the nut and the bolt head when it is not loose. If it is greater, it means that the nut is moving away. If it moves to one side away from the bolt head, it means that the bolt is loose, otherwise the bolt is not loose. In this process, the bolt is firstly quickly tested by shaking type to make up for the speed deficiency of spacing type detection. Secondly, the bolt is further tested by spacing type through the spacing type clamping mechanism 30 and the spacing type prompting mechanism 40 to make up for the reliability deficiency of shaking type detection, thereby balancing speed and reliability and improving the efficiency of bolt loosening detection. The shaking type clamping mechanism 20, the spacing type clamping mechanism 30 and the spacing type prompting mechanism 40 do not need electricity to maintain their operation, thereby improving the reliability of bolt detection.

[0085] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the present invention. A person skilled in the art should understand that the specific implementation of the present invention can be modified or replaced by equivalents, but these modifications or changes are within the scope of protection of the pending claims.
