Description

Technical Field

[0001] The present invention relates to the technical field of dam construction machinery, and in particular to a remotely controlled crawler traction slope rolling equipment and a construction method thereof. Background Art

[0002] The rolling of the slope cushion material and the slope stabilizing mortar of the concrete face rockfill dam is a key link in the construction of pumped storage power stations, and the construction quality directly affects the construction quality of the reservoir impervious panel. Currently, the commonly used rolling equipment includes road rollers and vehicle-mounted rolling tractors. Single road rollers are mostly used for rolling on the ground or at small slopes. The vehicle body drives the rolling wheel to roll, and it has good effects in terms of steering and rolling, but it is not suitable for slopes with larger gradients; the commonly used equipment on slopes is slope rolling equipment. The tractor is above the slope, and the winch drives the traction rope, and the traction rope pulls the roller upward. For the tractor of the slope rolling equipment, the rolling direction cannot be guaranteed, it is easy to deviate, and it is not easy to control the steering of the roller. In the case of high face rockfill dams, the entire construction process is more difficult to control, and situations such as slipping are likely to occur, which will greatly affect the construction quality and construction safety of the slope cushion material rolling.

[0003] In view of the above problems, a remotely controlled crawler equipment traction slope rolling construction technology is proposed, which effectively solves the disadvantages of the traditional slope roller such as the rolling direction cannot be guaranteed, it is easy to deviate, the time is long, and the stability of the construction process is difficult to control. At the same time, by setting pulleys and adjustable support platforms, precise adjustment control of the traction angle is realized, greatly improving the construction efficiency and ensuring the rolling quality. Summary of the Invention

[0004] In view of the technical problem that the rolling direction of the existing slope rolling equipment cannot be guaranteed during operation, it is easy to deviate, and it is not easy to control the steering of the roller, the present invention adopts the following technical solutions:

[0005] A construction method of a remotely controlled crawler traction slope rolling equipment, comprising the following steps:

[0006] S1. Investigate and check the terrain, geology and structures of the construction site, prepare construction materials and equipment, and then conduct on-site surveys and layout of the construction site;

[0007] S2. After the initial leveling of the slope surface, loosen the soil with a soil loosening machine, then spread the filler, and manually repair the positions with large undulations, and control the amplitude of protrusions and depressions within +5CM to -8CM;

[0008] S3. After the cushion slope is trimmed, atomize and sprinkle water to moisten the areas that need to be rolled. After 4 hours of drying, use a remote-controlled crawler-towed slope rolling equipment for rolling. Only vibrate when going uphill and do not vibrate when going downhill. Use the offset method or the lapping method. There should be an overlap between the two consecutive rolls, and the roll marks should overlap by 5 - 10 cm. During the rolling process, control the speed of the roller within 1.5 km / h and keep the speed uniform.

[0009] S4. After the cushion material slope is rolled qualified, carry out the construction of mortar slope protection. Keep the paving thickness of the mortar within 5 cm - 8 cm. Wait until the mortar is close to the initial setting time and then use the lapping method to statically roll twice.

[0010] In a preferred solution, the remote-controlled crawler-towed slope rolling equipment includes a crawler drive machine placed on the top platform of the dam body. The driving direction of the crawler drive machine is parallel to the extension direction of the dam slope, and there is a main support plate reserved at the top of the crawler drive machine that cannot rotate and is consistent with the vehicle body extension direction. One end of the upper surface of the main support plate near the head of the vehicle is provided with a cab that can rotate horizontally; a rotation support platform with an overall long strip structure is rotatably connected to the upper surface of the main support plate near the middle. The upper surface of the rotation support platform is detachably and fixedly connected with a main tower frame and a counterweight drive frame combined into a V-shaped structure with an upward opening; one side of the main support plate close to the dam slope is hinged with a support platform, and hook seats are fixed at both corners of the upper surface of the support platform far from the main support plate. One end of the main tower frame away from the counterweight drive frame extends obliquely above the middle of the horizontally placed support platform, and anti-detachment rope wheels are arranged near the four corners of the end of the main tower frame away from the counterweight drive frame. Winch mechanisms are arranged near both sides of the top of the counterweight drive frame. The winch mechanism includes a drive winch arranged near the top of the side surface of the counterweight drive frame. A multi-strand steel wire rope I is wound around the circumferential outer wall of the drive winch, and one end of the steel wire rope I away from the drive winch bypasses the two anti-detachment rope wheels on its side and is fixed to the hook seat below it; by setting the drive winch in cooperation with the support platform, after rolling one section of the dam slope, the rolling equipment can be dragged onto the support platform, and after moving forward a certain distance as a whole, it can be lowered again for staggered rolling.

[0011] The cam is an angularly oriented frame, the cam being arranged on a track with the roller ... There are two direction-changing fixed pulleys symmetrical about the center line of the fine-tuning slider, a U-shaped bracket is fixed to the upper surface of the counterweight driving frame near the oblique lower part of the variable diameter rope winding roller, and a groove-type slide rail with an upward opening is fixed to the top of the U-shaped bracket, the groove bottom of the groove-type slide rail is located at both ends and an electric push rod is fixed, and the ends of the extension rods of the two electric push rods are respectively fixed with arc-shaped symmetrical convex adjustment sliders, and the top of the convex adjustment slider is reserved with a strip-shaped toggle baffle rod, and the middle of the strip-shaped toggle baffle rod is opened with a soft steel wire Wear-resistant perforations adapted to the rope diameter; the two soft steel wire ropes are respectively fastened to the two symmetrical positions of the roller frame of the roller; when the device is pulling the roller frame on the slope upward to roll, once the rolling track is skewed due to uneven road surface, it is only necessary to control the extension rod of one of the electric push rods to change, at this time, the retraction length of the soft steel wire rope on the side can be lengthened, and then the roller begins to slowly correct to one side, thereby ensuring that the overall up and down movement maintains a straight line for rolling.

[0012] In a preferred solution, the soft steel wire rope is wound around at least once when passing through the direction-changing fixed pulley, which can prevent the soft steel wire rope from being unhooked when passing through the direction-changing fixed pulley.

[0013] In a preferred solution, spherical grooves are formed on the outer wall of the fine-tuning slider near both ends, and balls are embedded in the spherical grooves; a sink groove is formed on one end of the fine-tuning slider, and an electric slide rail 2 is fixed to the bottom of the groove of the V-shaped slide rail near one end of the sink groove, and the top of the extension rod of the electric slide rail 2 is fixed to the bottom of the sink groove; parts bent to both sides are provided on the lower frame of the main tower near the two soft steel wire ropes, so that the two soft steel wire ropes can be moved to one side when in use to correct the skewed path change to the greatest extent.

[0014] In a preferred embodiment, the reverse self-locking drive mechanism includes a motor frame fixed to the side of the counterweight drive frame, and a main drive motor is fixed to the side of the motor frame away from the counterweight drive frame. The top of the output shaft of the main drive motor is fixed with a worm through a coupling; both ends of the variable-diameter wire rope roller are reserved with roller heads, and a worm gear meshing with the worm is sleeved and fixed on the roller head near the worm end. The drive mechanism composed of the worm gear and the worm can not only pull the soft steel wire rope labor-savingly, but also prevent the soft steel wire rope from automatically rotating in the reverse direction due to accidental power failure, thereby preventing the road roller pulled on the half mountainside from suddenly sliding down, playing a protective role for the device and the construction workers below.

[0015] In a preferred embodiment, bearing frames are arranged near the four corners at the top of the main tower frame, and two horizontal and parallel long shaft rods are rotatably connected to the four bearing frames. The four anti-derailment rope wheels are respectively arranged at both ends of the two long shaft rods; and the upper long shaft rod is shorter than the lower long shaft rod; thus, when the steel wire ropes on both sides extend in different directions, the turning angle can be reduced, ensuring that the ropes will not derail or fall into the groove during slow pulling; ensuring that the loaded support platform can be lifted normally.

[0016] In a preferred embodiment, uneven anti-slip protrusions are reserved on the upper surface of the support platform, and a hook I is fixed at one end of each steel wire rope I away from the drive winch; the size of the hook I is adapted to the hook seat on the support platform; ensuring that the equipment carrying the road roller frame and the road roller is lifted and then advanced to roll the next area.

[0017] In a preferred embodiment, two rotatable articulated hanging blocks are arranged on one side of the road roller frame close to the crawler drive machine, and a hook II adapted to the articulated hanging blocks is arranged at the end of each of the two soft steel wire ropes; mounting planes for fixing the carrier frame are formed near the middle on both sides of the counterweight drive frame; the device can be quickly docked and installed during use.

[0018] In a preferred embodiment, parallel fixed pipe frames are respectively fixed at the long sides on both sides of the rotating turntable. Telescopic rods are fixed in both fixed pipe frames. The extension rods of the two telescopic rods all face away from the main tower frame. The same counterweight block is fixed at the same end of the extension rods of the two telescopic rods, and a horizontally extending T-shaped slide rail beam is fixed on one side of the counterweight block close to the counterweight drive frame; a guiding sliding frame adapted to the cross-sectional shape of the T-shaped slide rail beam is fixed on the upper surface of the rotating turntable; by arranging the counterweight block, when the support platform is bearing and running, the counterweight block can be extended in the reverse direction to ensure the balance of both sides of the vehicle body and avoid tipping due to excessive weight on the side close to the slope.

[0019] The beneficial effects of the present invention are:

[0020] 1. By setting up a driving winch in conjunction with the supporting platform, the roller can be dragged to the supporting platform after one slope of the dam body is rolled, and then lowered again after the whole body moves forward for a certain distance for staggered rolling.

[0021] 2. By setting the variable diameter rope roller and the bar-shaped toggle lever for adjusting the winding position of the soft steel wire rope, when the device is pulling the roller frame on the slope upward to roll, if the rolling track is skewed due to uneven road surface, it is only necessary to control the extension rod of one of the electric push rods to change. At this time, the retraction length of the soft steel wire rope on that side can be lengthened, and then the roller begins to slowly correct to one side, thereby ensuring that the overall up and down movement maintains a straight line for rolling.

[0022] 3. The drive mechanism composed of a worm gear and a worm can not only pull the soft steel wire rope with less effort, but also prevent the soft steel wire rope from automatically rotating in the opposite direction due to an accidental power failure, thereby preventing the roller pulled on the hillside from suddenly sliding down, thus protecting the device and the construction workers below.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] Please refer to Figure 1 , a construction method of a remote-controlled crawler traction slope rolling equipment, including the following steps:

[0036] S1. Investigate and check the terrain, geology and structure conditions of the construction site, prepare construction materials and equipment, and then conduct on-site survey and layout of the construction site;

[0037] S2. After the slope is initially leveled, loosen the soil with a soil loosening machine, then spread the filler, and manually repair the positions with large undulations, and control the amplitude of protrusions and depressions within +5CM to -8CM;

[0038] S3. After the cushion slope is trimmed, atomize and sprinkle water on the places to be rolled, and after 4 hours of drying, use the remote-controlled crawler traction slope rolling equipment to roll. Only vibrate when going uphill and do not vibrate when going downhill. Use the stagger method or the lap method. There should be an overlap between the front and rear two rolls, and the rolling marks should overlap by 5-10CM. During the rolling process, control the speed of the roller within 1.5 km / h and keep the speed uniform;

[0039] S4. After the cushion layer material slope is rolled and qualified, the mortar slope protection construction is carried out. The paving thickness of the mortar is kept within 5CM - 8CM. When the mortar is close to the initial setting time, it is statically rolled twice by the lapping method.

[0040] Refer to Figures 2 to 10 , the remote-controlled crawler traction slope rolling equipment includes a crawler drive 17 placed on the top platform of the dam body 1. The driving direction of the crawler drive 17 is parallel to the slope extension direction of the dam body 1. And a main support plate 15 that cannot rotate and is consistent with the vehicle body extension direction is reserved at the top of the crawler drive 17. A cab 16 that can rotate horizontally is arranged at one end of the upper surface of the main support plate 15 close to the vehicle head; a rotating support platform 19 with an overall long strip structure is rotatably connected to the upper surface of the main support plate 15 close to the middle. The upper surface of the rotating support platform 19 is detachably and fixedly connected with a main tower frame 6 and a counterweight drive frame 11 that are combined into an upward-opening V-shaped structure; a support platform 4 is hinged to one side of the main support plate 15 close to the slope of the dam body 1. And hook seats are fixed at both corners of the upper surface of the support platform 4 away from the main support plate 15. One end of the main tower frame 6 away from the counterweight drive frame 11 extends obliquely above the middle of the support platform 4 in a horizontal state. And anti-detachment rope wheels 7 are arranged at the four corners of one end of the main tower frame 6 away from the counterweight drive frame 11. Winch mechanisms are arranged near both sides of the top of the counterweight drive frame 11. The winch mechanism includes a drive winch 21 arranged on the side of the counterweight drive frame 11 close to the top. A multi-strand steel wire rope 5 is wound around the circumferential outer wall of the drive winch 21. And one end of the steel wire rope 5 away from the drive winch 21 bypasses the two anti-detachment rope wheels 7 on the same side and is fixed to the hook seat below it;

[0041] Specifically, through the cooperation of the drive winch 21 and the support platform 4, after rolling one section of the slope of the dam body 1, the rolling equipment is dragged onto the support platform 4. After moving forward a certain distance as a whole, it is lowered again for staggered rolling.

[0042] Refer to Figures 2 - 10 , a retractable winch mechanism is also arranged on the upper surface of the counterweight drive frame 11 close to the middle. And the retractable winch mechanism includes two parallel and vertical bearing frames 29 fixed on both sides of the counterweight drive frame 11. The same variable-diameter winch roller 10 is rotatably connected between the two bearing frames 29. The diameters of both ends of the variable-diameter winch roller 10 are equal and smaller than the diameter of the middle part. And a reverse self-locking drive mechanism is arranged at one end of one side of the counterweight drive frame 11 close to the variable-diameter winch roller 10. Soft steel wire ropes 28 are wound around the circumferential outer wall of the variable-diameter winch roller 10 close to both ends. And the two soft steel wire ropes 28 away from the variable-diameter winch roller 10 are fixed to the same roller frame 3 of the road roller. The size of the roller frame 3 of the road roller is smaller than the distance between the two hook seats. And a road roller drum 2 is arranged in the middle of the roller frame 3 of the road roller;

[0043] A V-shaped slide rail 18 with an opening upward is welded on the upper surface of the lower frame in the middle of the main tower 6, and a fine-tuning slider 23 is slidably connected in the slide groove of the V-shaped slide rail 18, and an axial rod frame 2301 is fixed to the upper surface of the fine-tuning slider 23 near both ends, and two direction-changing fixed pulleys symmetrical about the center line of the fine-tuning slider 23 are rotatably connected between the two axial rod frames 2301, and a U-shaped bracket 8 is fixed to the upper surface of the counterweight driving frame 11 near the oblique lower side of the variable diameter rope winding roller 10, and a groove-type slide rail 9 with an opening upward is fixed to the top of the U-shaped bracket 8, and an electric push rod 30 is fixed to the bottom of the groove-type slide rail 9 at both ends, and the ends of the extension rods of the two electric push rods 30 are respectively fixed with arc-shaped symmetrical convex adjustment sliders 27, and the top of the convex adjustment slider 27 is reserved with a strip-shaped toggle stopper, and the middle of the strip-shaped toggle stopper is provided with a wear-resistant perforation matched with the diameter of the soft steel wire rope 28;

[0044] Two soft steel wire ropes 28 are respectively fastened to two symmetrical positions of the roller frame 3 of the roller;

[0045] Specifically, when the device is pulling the roller frame 3 on the slope upward for rolling, once the rolling track becomes skewed due to uneven road surface, it is only necessary to control the extension rod of one of the electric push rods 30 to change, so that the retraction length of the soft steel wire rope 28 on the side can be lengthened, and then the roller 2 begins to slowly correct to one side, thereby ensuring that the overall up and down movement maintains a straight line for rolling.

[0046] Reference Figure 5 The soft steel wire rope 28 is wound around at least one circle when passing through the direction-changing fixed pulley, which can prevent the soft steel wire rope 28 from being unhooked when passing through the direction-changing fixed pulley.

[0047] Reference Figure 4 and Figure 10 The outer wall of the fine-tuning slider 23 is provided with spherical grooves near both ends, and balls are embedded in the spherical grooves. A sink groove is provided at one end of the fine-tuning slider 23, and an electric slide rail 2 is fixed to the bottom of the groove of the V-shaped slide rail 18 near the end of the sink groove, and the top of the extension rod of the electric slide rail 2 is fixed to the bottom of the sink groove; the lower frame of the main tower 6 is provided with parts bent to both sides near the two soft steel wire ropes 28. When in use, the two soft steel wire ropes 28 can be moved to one side as a whole to correct the skewed path change to the greatest extent.

[0048] Reference Figure 4 , Figure 7 and Figure 10, the reverse self-locking drive mechanism includes a motor mount fixed to the side of the counterweight drive frame 11, and a main drive motor 31 is fixed to the side of the motor mount away from the counterweight drive frame 11. The top of the output shaft of the main drive motor 31 is fixed with a worm 25 through a coupling; both ends of the variable-diameter rope winding roller 10 are reserved with roller heads, and a worm gear 26 that meshes with the worm 25 is sleeved and fixed on the roller head near one end of the worm 25;

[0049] Specifically, the drive mechanism composed of the worm gear 26 and the worm 25 not only can pull the soft steel wire rope 28 with less effort, but also prevents the soft steel wire rope 28 from automatically rotating in the reverse direction due to accidental power failure, thereby preventing the road roller 2 pulled on the half mountainside from suddenly sliding down, playing a protective role for the device and the construction workers below.

[0050] Refer to Figure 3 and Figure 8 , bearing mounts 22 are provided near the four corners at the top of the main tower frame 6, and two horizontal and parallel long shaft rods are rotatably connected to the four bearing mounts 22. Four anti-derailment rope wheels 7 are respectively arranged at both ends of the two long shaft rods; and the upper long shaft rod is shorter than the lower long shaft rod; thus, the turning angle can be reduced when the steel wire ropes on both sides extend in opposite directions, ensuring that they will not derail or fall into the groove during slow pulling; ensuring that the loaded support platform 4 can be lifted normally.

[0051] Refer to Figure 2 and Figure 10 , anti-slip protrusions with uneven surfaces are reserved on the upper surface of the support platform 4, and a hook 501 is fixed to each end of the steel wire rope 5 away from the drive winch 21; the size of the hook 501 is adapted to the hook seat on the support platform 4; ensuring that the equipment carrying the road roller frame 3 and the road roller 2 is lifted and then advanced to roll the next area.

[0052] Refer to Figure 4 , Figure 6 and Figure 8 , two rotatable articulated hanging blocks 24 are arranged on one side of the road roller frame 3 close to the crawler drive 17, and hooks II adapted to the articulated hanging blocks 24 are arranged at the ends of the two soft steel wire ropes 28; mounting planes 1101 for fixing the carrier frame 29 are opened near the middle of both sides of the counterweight drive frame 11; the device can be quickly docked and installed during use.

[0053] Refer to Figure 3 and Figure 6, on both long sides of the rotating turntable 19, there are respectively fixed parallel fixed pipe frames. Telescopic rods 14 are fixed in both fixed pipe frames. The extension rods of the two telescopic rods 14 all face away from the main tower 6. The same counterweight 13 is fixed at the same end of the extension rods of the two telescopic rods 14. And a horizontally extending T-shaped slide rail beam 12 is fixed on the side of the counterweight 13 close to the counterweight drive frame 11; A guiding slide frame 20 with a cross-sectional shape adapted to that of the T-shaped slide rail beam 12 is fixed on the upper surface of the rotating turntable 19;

[0054] Specifically, by setting the counterweight 13, when the supporting platform 4 bears the weight and operates, the counterweight 13 can be extended in the reverse direction to ensure the balance of both sides of the vehicle body and prevent the side close to the slope from being overweight and causing rollover.

[0055] Working principle: When the device is in use, first lower the supporting platform 4 on the side of the device, and then start the main drive motor 31 on the side of the counterweight drive frame 11 to pull the two soft steel wire ropes 28 below, and then fix the second hook at the end on the two articulated hanging blocks 24 at the end of the roller frame 3 of the roller compactor. After that, the main drive motor 31 can be started continuously until the roller frame 3 and the roller 2 of the roller compactor are slowly rolled along the slope downward; After a longitudinal area is rolled, pull the roller frame 3 together with the roller 2 of the roller compactor onto the supporting platform 4, and then start the rope winding mechanism to lift the supporting platform 4 together with the roller frame 3;

[0056] At the same time, extend the counterweight 13 on the other side of the crawler drive 17 to make the counterweights on both sides almost equal. Then move the crawler drive 17 forward to the next pressing area; When the device is pulling and rolling the roller frame 3 of the roller compactor on the slope upward, once the rolling track is skewed due to uneven road surface, just control the change of the extension rod of one of the electric push rods 30. At this time, the retraction length of the soft steel wire rope 28 on the corresponding side can be made longer, and then the roller 2 can start to be corrected slowly to one side, so as to ensure that the overall up and down movement maintains a straight line rolling;

[0057] The driving mechanism composed of the worm gear 26 and the worm 25 not only can pull the soft steel wire rope 28 labor-savingly, but also prevent the soft steel wire rope 28 from automatically rotating in the reverse direction due to accidental power failure, and then prevent the roller 2 pulled on the half slope from suddenly sliding down, playing a protective role for the device and the construction personnel below.

[0058] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
