Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a hoisting device for hoisting and installing a gate used in water conservancy and flood control projects. Background Art

[0002] In water conservancy and flood control projects, gates are control facilities used to close and open water discharge channels. By controlling the valve plate to lift and lower, the valve is opened and closed to intercept water flow, control water level, regulate flow, and discharge sediment and floating objects. They are an important part of water conservancy and flood control buildings. According to the appearance of the gate, they can be divided into six types: plane gates, arc gates, miter gates, arch gates, ball gates and cylinder gates. Among them, plane gates are usually rectangular plates made of steel or cast iron, with two rollers installed on each side. During the installation process, people use a crane to lift the gate to the top of the gate. A beam is installed above the gate to keep the gate upright, pass through the square groove on the beam and then insert it into the slide groove on the inner wall of the gate. The rollers slide in the slide groove to support the lifting and lowering of the gate.

[0003] During the current gate hoisting process, since the gate is directly hoisted upright and has poor stability, it is easy to shake and difficult to insert directly into the beam. Therefore, people usually use four ropes to suspend four corner rollers to hoist the gate horizontally and stably. The crane moves the gate to the beam, and the gate is obstructed by the side wall of the beam and placed tilted in the beam. The staff on the beam removes the two ropes on the front side, and when the crane hoists it again, it uses the two ropes on the back side to lift the gate upright, and then cooperates with manual support to make the gate pass smoothly through the square groove on the beam.

[0004] The existing gate hoisting and installation process requires two hoisting operations, one horizontal hoisting and the other vertical hoisting. The state switching of the two hoisting operations depends on manual operation on the beam. Since the gate is too heavy and it is not stable to be placed at an angle on the beam, manual operation has the problems of slow hoisting speed and low safety, and the gate cannot be continuously flipped and hoisted. In addition, manual support is relied on to keep the gate connected to the square groove, and automatic centering cannot be achieved. It should be noted that the gate is in an unstable hanging state at this time. If it swings left and right, it will directly cause an engineering accident and threaten the personal safety of the staff. Utility Model Content

The number of support blocks is four, and they are symmetrically distributed at the four corners inside the rectangular frame.

The two rope winding rollers in the same group are installed on the same rotating shaft.

[0015] A method for using a hoisting and installation lifting device for a gate in a water conservancy flood control project includes the following steps:

[0016] S1: The electric push rod extends to push the support block out of the second through groove, and the gate to be installed is placed into the rectangular frame. The four corners of the bottom of the gate are inserted into the square grooves, and the inner walls of the square grooves are used to position the placement of the gate to ensure that the gate is at the middle of the rectangular frame at this time.

[0017] S2: The clamping motor drives the clamping screw rod to rotate. The clamping screw rod rotates in the threaded groove to drive the movable column to extend out of the first through groove, so that the movable column clamps the middle parts of the left and right side walls of the gate.

[0018] S3: The traction rope is sleeved on the four rollers on both sides of the gate, the first lifting rope and the second lifting rope are hung on the hook, the crane is started, and the cantilever drives the rectangular frame and the gate to move to the cross beam through the hook.

[0019] S4: The mounting seat is placed on the front and back side walls of the cross beam. The mounting motor is started to drive the mounting screw rod to rotate. The mounting screw rod drives the clamping plate to move towards one side of the mounting seat through the screw hole, and the inner wall of the cross beam is squeezed by the clamping plate to temporarily install the rectangular frame on the cross beam.

[0020] S5: The electric push rod retracts and pulls the support block back into the second through slot, and the drive motor at the front side of the drive seat rotates, driving the rope winding roller to rotate through the rotating shaft, so that the traction rope at the front side of the gate is retracted, and the drive motor at the rear side of the drive seat is reversed, so that the traction rope at the rear side of the gate is extended, and the gate is pulled by the pulling force of the traction rope at the front side to drive the clamping block to rotate relative to the movable column, so that the gate is flipped around the axis of the movable column to an upright state;

[0021] S6: Two laser distance measuring sensors emit laser beams downward to detect the position of the slot above the beam. If the data measured by the two laser distance measuring sensors are one long and one short, it means that one laser beam passes through the square slot. At this time, the gate in the upright state is not aligned with the square slot.

[0022] S7: The clamping motor drives the clamping screw to rotate, driving the movable column on one side to extend and the movable column on the other side to retract, and the gate is pushed to move left and right while being clamped by the clamping blocks on both sides, and the gate is fine-tuned laterally until the data detected by the two laser distance measuring sensors are the distance from themselves to the bottom surface of the beam. At this time, the gate is aligned with the square slot;

[0023] S8: Loosen the clamping mechanism on one side and rotate with the two drive motors so that the rope winding rollers are in the rope releasing state. The traction rope is extended to suspend the gate and move it downward until the gate is inserted into the square groove. After the roller moves to the square groove position, remove the traction rope from the roller, so that the gate can be lowered by the roller and inserted into the gate to complete the installation.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] 1. The hoisting equipment for hoisting and installing the gate of this water conservancy and flood control project is set up with a flipping drive mechanism. The rectangular frame is suspended by the first hoisting rope to maintain the horizontal and stable hoisting of the gate. The gate is suspended under the driving seat by the traction rope. The front driving motor rotates, and the rope winding roller is driven to rotate through the rotating shaft to shrink the traction rope on the front side of the gate. The rear driving motor is reversed to extend the traction rope on the rear side of the gate. The gate is pulled around the axis of the movable column to the vertical state by the pulling force of the front traction rope, realizing the automatic switching function of the horizontal hoisting and vertical hoisting state of the gate, and the two hoisting methods are carried out continuously without manual secondary suspension.

[0026] 2. The gate hoisting and installation lifting equipment used in this water conservancy and flood control project, by setting up a supporting mechanism and a clamping mechanism, four support blocks support the gate in a rectangular frame, and the inner wall of the square groove limits the gate and the rectangular frame. On the basis of the gate being centered, the clamping motor drives the movable column to extend from the first through groove, and the clamping blocks clamp the two sides of the gate. On the one hand, it can ensure that the gate is flipped around the axis of the movable column in the rectangular frame. After flipping, the gate is still aligned with the rectangular frame, which is convenient for the subsequent insertion of the square groove of the crossbeam. On the other hand, the stability of the gate is maintained during the lifting of the rectangular frame.

[0027] 3. The gate hoisting and installation lifting equipment used in this water conservancy and flood control project is installed by setting a mounting seat and a clamping plate. The rectangular frame is installed on the beam through a hoist. The side wall of the beam is inserted into the inner side of the mounting seat. The mounting motor drives the mounting screw to rotate. The mounting screw drives the clamping plate to move toward one side of the mounting seat through the screw hole. The clamping plate is used to squeeze the inner wall of the beam so that the rectangular frame is temporarily installed on the beam. The subsequent flipping and installation of the gate are positioned to achieve the effect of keeping the clamping point relatively still before the gate is flipped, ensuring stable flipping of the gate.

[0028] 4. The gate hoisting and installation lifting equipment of this water conservancy and flood control project is installed by setting a laser distance measuring sensor. After the clamping block clamps the gate, the laser distance measuring sensors are on the left and right sides of the gate. The two laser distance measuring sensors emit laser beams downward to detect the position of the upper groove of the beam. If the data detected by the two laser distance measuring sensors are the distance from themselves to the bottom of the beam, the gate and the square groove are aligned at this time. If the data measured by the two laser distance measuring sensors are one long and one short, it means that a laser beam passes through the square groove. At this time, the gate in the upright state is not aligned with the square groove, and then the clamping motor drives the clamping screw to rotate, driving one side of the movable column to extend and the other side of the movable column to retract. While clamping the clamping blocks on both sides, the gate is pushed to move left and right, and the gate is fine-tuned laterally to achieve automatic adjustment of the gate and square groove alignment to ensure that the gate passes through the beam smoothly. The clamping mechanism is used to clamp the gate for stable hoisting, assist the gate in flipping, and adjust the gate and the square groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] like Figures 1 to 7As shown, the hoisting equipment for hoisting and installing the gate of the water conservancy and flood control project in this embodiment includes a crane 1, a cantilever 2 installed on the top of the crane 1, a wire rope 3 installed on the cantilever 2, and a hook 4 suspended at the bottom of the wire rope 3. A first hoisting rope 5 is suspended on the hook 4. A rectangular frame 6 is connected to the bottom of the first hoisting rope 5. A power supply, line, communication and control module supporting the normal operation of various electrical equipment are installed on one side of the rectangular frame 6. A gate 7 is arranged inside the rectangular frame 6. The width of the inner wall of the rectangular frame 6 is larger than the width of the gate 7, so that the gate 7 can move left and right in the rectangular frame 6. The gate 7 is adjusted to be centered with the square groove. The left and right sides of the rectangular frame 6 are A first through slot 13 is provided in the middle of each side wall, and a clamping mechanism 8 is installed in the first through slot 13. The clamping mechanism 8 is used to clamp the gate 7 for stable hoisting, to assist the gate 7 in flipping, and to adjust the gate 7 to be aligned with the square slot. A second through slot 14 is provided on the left and right side walls of the rectangular frame 6 in front and behind the first through slot 13. A supporting mechanism 9 is installed in the second through slot 14 to support the gate 7 in the middle of the rectangular frame 6. A traction rope 10 is sleeved on the left and right sides of the gate 7, and a flip driving mechanism 11 is connected to the top of the traction rope 10. A second lifting rope 12 is suspended between the top of the flip driving mechanism 11 and the hook 4;

[0041] The flip driving mechanism 11 includes a driving seat 111, a groove 112 is provided inside the driving seat 111, a rope winding roller 113 is arranged inside the groove 112, a rotating shaft 114 is provided in the middle of the rope winding roller 113, a driving bearing 115 is connected between one end of the rotating shaft 114 and the driving seat 111, the rotating shaft 114 is rotatably connected to the driving seat 111 through the driving bearing 115, two rope winding rollers 113 are installed on the rotating shaft 114, which are respectively used to wind two traction ropes 10 connected to the front side of the gate 7, and a driving motor 116 is connected to the other end of the rotating shaft 114, and the shaft end of the driving motor 116 is connected to the rotating shaft 114. The driving motor 116 is essentially a motor with a forward and reverse circuit. The rope winding roller 113 is controlled by forward and reverse rotation to pull the traction rope 10 to reel in. A guide roller 117 is embedded in the bottom of the driving seat 111. Since the traction rope 10 extending out of the driving seat 111 is partially bent, the guide roller 117 is used to support the traction rope 10 to prevent the traction rope 10 from rubbing against the driving seat 111 and causing wear. Fixed blocks 118 are connected to the four corners of the top of the driving seat 111. The fixed blocks 118 have holes for connecting the traction rope 10. The power supply, lines and communication modules required for the normal operation of the driving motor 116 are installed on the top of the driving seat 111.

[0042] Specifically, connection blocks 61 are connected to the four corner positions of the upper surface of the rectangular frame 6. The connection blocks 61 are provided with openings at the top for connecting the first lifting rope 5. The top of the rectangular frame 6 is connected to the first lifting rope 5 through the connection blocks 61. Mounting seats 62 are connected to the edges of the front and rear side walls of the rectangular frame 6. A clamping plate 63 is provided at the bottom of the mounting seat 62. A clamping block 64 is connected to the top of the clamping plate 63. A clamping groove 65 is formed at the bottom of the mounting seat 62. The clamping block 64 is integrally connected to the clamping plate 63. The cross-sections of the clamping block 64 and the clamping groove 65 are both T-shaped. The clamping block 64 is clamped inside the clamping groove 65 and slides. A screw hole 66 is formed through the clamping plate 63. A mounting screw 67 is disposed through the screw hole 66. The outer diameter of the mounting screw 67 is adapted to the inner diameter of the screw hole 66. A mounting bearing 68 is connected between the mounting screw 67 and the mounting seat 62. One end of the mounting screw 67 passes through the mounting seat 62 through the mounting bearing 68 and is connected to a mounting motor 69. The mounting motor 69 is essentially a motor with a forward and reverse circuit. One end of the mounting screw 67 is rotatably connected to the mounting seat 62 through the mounting bearing 68. The other end of the mounting screw 67 passes through the clamping plate 63 through the screw hole 66. The mounting screw 67 is threadedly connected to the clamping plate 63 through the screw hole 66. The mounting motor 69 drives the mounting screw 67 to rotate, and the mounting screw 67 drives the clamping plate 63 to move toward one side of the mounting seat 62 through the screw hole 66.

[0043] Further, the mounting seat 62 is integrally connected to the rectangular frame 6. The mounting seat 62 and the clamping plate 63 form an inverted U shape. The distance between the mounting seats 62 on the front and rear sides of the rectangular frame 6 matches the width dimension of the cross beam of the gate 7. When the rectangular frame 6 is placed on the cross beam, the inner walls of the mounting seats 62 on the front and rear sides are close to the outer side walls of the cross beam. The mounting seat 62 and the clamping plate 63 are respectively located on the front and rear sides of the side wall of the cross beam of the gate 7. The clamping plate 63 is slidably connected to the mounting seat 62 through the clamping block 64. By moving the clamping plate 63 toward one side of the mounting seat 62, the clamping plate 63 presses the inner walls of the front and rear sides of the cross beam, so that the rectangular frame 6 is temporarily installed on the cross beam, positioning the subsequent flipping and installation of the gate 7.

[0044] Furthermore, the clamping mechanism 8 includes a movable column 81, one side of the movable column 81 is connected to a clamping block 82, a rubber pad is laid on the side of the clamping block 82 away from the movable column 81, which is used to increase the friction between the clamping block 82 and the gate 7 and enhance the clamping effect of the clamping block 82, and a threaded groove 84 is provided on the other side of the movable column 81, and a laser ranging sensor 83 is installed at the bottom of the side of the movable column 81 close to the clamping block 82. The actual model of the laser ranging sensor 83 is selected according to the actual size of the movable column 81 and the ranging range. The laser beam emission direction of the laser ranging sensor 83 is downward, and the laser ranging sensor 83 is electrically connected to the control module installed on one side of the rectangular frame 6 through the circuit. There are two laser ranging sensors 83, which are symmetrically distributed on both sides of the gate 7 after the clamping mechanism 8 clamps the gate 7, and the spacing between the light beams emitted by the two laser ranging sensors 83 is the same as the beam spacing. The width of the upper groove corresponds to that of the upper groove. Only after the gate 7 is aligned with the square groove, the data detected by the two laser ranging sensors 83 are the distance from themselves to the bottom surface of the beam. A clamping screw 85 is arranged inside the threaded groove 84. The outer diameter of the clamping screw 85 is matched with the inner diameter of the threaded groove 84. A fixing frame 86 is arranged on the side of the clamping screw 85 away from the movable column 81. The fixing frame 86 is used to support the installation of the clamping screw 85. A clamping bearing 87 is installed between the clamping screw 85 and the fixing frame 86. One end of the clamping screw 85 passes through the fixing frame 86 and is connected to a clamping motor 88. The clamping motor 88 is installed on the side wall of the fixing frame 86. The clamping screw 85 is driven to rotate by the clamping motor 88. The clamping screw 85 rotates in the threaded groove 84 to drive the movable column 81 to extend from the first through groove 13, so that the movable column 81 drives the clamping block 82 to clamp in the middle of the left and right side walls of the gate 7.

[0045] Furthermore, the movable column 81 is in the shape of a rectangular column, and the width of the movable column 81 is matched with the width of the inner wall of the first through groove 13. The movable column 81 is slidably connected to the first through groove 13. The clamping block 82 is in the shape of a cylinder with a T-shaped longitudinal section. The clamping block 82 is rotatably connected to the movable column 81 via a bearing. When the clamping block 82 clamps the gate 7, it relies on the friction with the side wall of the gate 7 to remain relatively still with the gate 7. When the traction rope 10 pulls the gate 7 to flip, the gate 7 drives the clamping block 82 to rotate relative to the movable column 81 via the bearing, and the two clamping blocks 82 are respectively in contact with the left and right side walls of the gate 7.

[0046] Furthermore, the fixing bracket 86 is in a U shape and is fixedly welded to the outer side wall of the rectangular frame 6. One end of the clamping screw rod 85 is rotatably connected to the fixing bracket 86 through a clamping bearing 87, and the other end of the clamping screw rod 85 is threadedly connected to the movable column 81 through a thread groove 84. By rotating the clamping screw rod 85 in the thread groove 84, the movable column 81 is driven to extend from the first through groove 13. Among them, two clamping motors 88 are synchronously driven through an encoder. When the extending lengths of the movable columns 81 on both inner side walls of the rectangular frame 6 are the same, they are used to clamp the gate 7. When one movable column 81 extends and the other movable column 81 retracts, while clamping with the clamping blocks 82 on both sides, the gate 7 is pushed to move left and right.

[0047] Furthermore, the support mechanism 9 includes a support block 91. A square groove 92 is provided on the upper surface of the support block 91, and the square groove 92 is on the side of the upper surface of the support block 91 close to the gate 7. One side of the fixed block 118 close to the second through groove 14 is connected with an electric push rod 93. The electric push rod 93 is installed on the side wall of the rectangular frame 6. The actual model of the electric push rod 93 is selected according to the actual size of the support block 91. The support block 91 is in an L shape, and the number of support blocks 91 is four, and they are symmetrically distributed at the four inner corners of the rectangular frame 6. The support block 91 is sleeved on the four corners of the bottom of the gate 7 through the square groove 92. By using the four support blocks 91 to support the four corners of the gate 7, the gate 7 is placed in the rectangular frame 6, and the telescopic strokes of the four electric push rods 93 are controlled to be the same, ensuring that the gate 7 is placed centered in the rectangular frame 6. The support block 91 is connected to the telescopic end of the electric push rod 93, and the extension and retraction of the support plate are realized by the telescopic movement of the electric push rod 93, avoiding blocking the flipping of the gate 7.

[0048] Furthermore, the bottom of the second lifting rope 12 is connected to the fixed block 118, and the top of the second lifting rope 12 is suspended on the hook 4. During the process of adjusting the horizontal centering of the gate 7, the gate 7 moves horizontally in the rectangular frame 6 and pulls the driving seat 111 to move horizontally through the traction rope 10. By suspending the driving seat 111 on the hook 4 through the second lifting rope 12, the second lifting rope 12 can be tilted to balance the traction rope 10, avoiding the situation that the traction ropes 10 on both sides of the gate 7 are tilted too much and the gate 7 is tilted. The bottom of the traction rope 10 is sleeved on the rollers on the left and right sides of the gate 7. The bottom of the traction rope 10 is in a ring shape and can be directly sleeved on the central axis of the roller. The top of the traction rope 10 is wound around the rope winding rollers 113. The number of rope winding rollers 113 is four, and two of them are in a group and are arranged symmetrically front and back in the groove 112. The two rope winding rollers 113 in the same group are both installed on the same rotating shaft 114.

[0049] A usage method of a hoisting and installation lifting device for a gate in a water conservancy flood control project includes the following steps:
