Description

Technical Field

[0001] This invention relates to the field of track slab production technology, and in particular to a track slab production line. Background Technology

[0002] An embedded sleeve is a tubular component pre-embedded during the production of track slabs, typically used to install track slab fastening systems. Before the track slab is cast, the embedded sleeve must be precisely installed into the designated position in the track slab mold to ensure a tight fit between the embedded sleeve and the track slab during casting and to meet the connection accuracy requirements in subsequent construction.

[0003] In traditional track slab production, pre-embedded sleeves are typically manufactured in advance and then installed into the track slab mold after forming. The various stages of pre-embedded sleeve production and installation are independent of each other, lacking coordination between the different production equipment used for pre-embedded sleeves and between these equipment and the track slab production equipment. This results in cumbersome material handling and low production efficiency. Furthermore, the installation of pre-embedded sleeves is currently usually done manually, which is labor-intensive, and the installation accuracy is significantly affected by manual operation, leading to large installation quality errors and inconsistent track slab production quality. Summary of the Invention

[0004] The main objective of this invention is to propose a production line for track slabs, which aims to solve the technical problems of low production efficiency, high labor intensity, and unstable production quality of track slabs in the prior art.

The pre-embedded sleeve processing device includes a sleeve feeding mechanism, a spiral reinforcement forming mechanism, a cutting mechanism, a twisting mechanism, a first clamping mechanism, a second clamping mechanism, a first conveyor belt, and a second conveyor belt. The sleeve feeding mechanism, the cutting mechanism, and the twisting mechanism are sequentially and alternately arranged on the first conveyor belt. The first clamping mechanism is located between the spiral reinforcement forming mechanism and the twisting mechanism, and the second clamping mechanism is located between the first conveyor belt and the second conveyor belt. The sleeve feeding mechanism is used to feed sleeves onto the first conveyor belt. The cutting mechanism is used to cut the outer wall of the sleeve to form threads. The spiral reinforcement forming mechanism is used to process the reinforcing bars into spiral reinforcements. The first clamping mechanism is used to clamp the spiral reinforcements and convey them to the twisting mechanism. The twisting mechanism is used to... The spiral rib is screwed into the thread of the sleeve so that the spiral rib is sleeved on the outside of the sleeve. The second clamping mechanism is used to clamp the sleeve with the spiral rib and place it on the second conveyor belt. The second clamping mechanism can also fit a fixing sleeve on the spiral rib to form the embedded sleeve. The embedded sleeve installation device includes a frame, a moving mechanism and a third clamping mechanism. A casting space is formed in the frame.

[0007] In one embodiment, the spiral forming mechanism includes a winding drum, a straightening assembly, a hydraulic cutting device, a bending assembly, and a feeding drive arranged sequentially at intervals. The feeding drive is used to sequentially convey the reinforcing bars wound by the winding drum to the straightening assembly, the hydraulic cutting device, and the bending assembly. The straightening assembly includes multiple rollers arranged in two rows at intervals, forming a straightening channel between the two rows of rollers for the reinforcing bars to pass through. The two rows of rollers can respectively roll the upper and lower sides of the reinforcing bars to straighten them. The hydraulic cutting device is used to cut the reinforcing bars into segments, and the bending assembly is used to bend the segments into the spiral reinforcement.

[0008] In one embodiment, the bending assembly includes a bending roller, a pressure block, and a servo slide. The pressure block is spaced apart from the bending roller and can swing toward or away from the bending roller. The servo slide is connected to the rotating shaft of the bending roller and can drive the bending roller to rotate and slide along its axial direction.

[0009] In one embodiment, the twisting mechanism includes a bracket, a first lifting rod, a mounting component, a lifting motor, and a twisting motor. The bracket is supported on the first conveyor belt and has a twisting channel through which the first conveyor belt passes. The lifting motor is mounted on the bracket, and its movable end is connected to one end of the first lifting rod, enabling the lifting motor to lift the first lifting rod. The twisting motor is located at the other end of the first lifting rod, and its output shaft is connected to the mounting component. The mounting component can mount the spiral rib, and the twisting motor can drive the mounting component to rotate.

[0010] In one embodiment, the moving mechanism includes a truss, a tilting assembly, and a lifting assembly. A first guide rail extending longitudinally is provided on the frame.

The tilting assembly can move relative to the truss along the second guide rail, and the tilting assembly can drive the lifting assembly to rotate relative to the truss. The lifting assembly can drive the third clamping mechanism to move vertically relative to the truss.

[0011] In one embodiment, the flipping assembly includes a fixed plate, a flipping plate, and a flipping drive member. The edge of the flipping plate is hinged to the edge of the fixed plate. The flipping drive member can drive the flipping plate to rotate relative to the fixed plate. The side of the fixed plate opposite to the flipping plate is slidably connected to the second guide rail. The side of the flipping plate opposite to the fixed plate is movably connected to the lifting assembly.

[0012] In one embodiment, a snap-fit ​​block is installed on the side of the flip plate opposite to the fixed plate. The lifting assembly includes a second lifting rod and a lifting drive component.

[0014] In one embodiment, the clamping member includes a connecting plate, a clamping drive, and a plurality of clamping claws. The connecting plate is connected to the movable end of the telescopic rod. The plurality of clamping claws are all disposed on the side of the connecting plate away from the telescopic rod, and the plurality of clamping claws are spaced apart.

[0030] In traditional track slab production, pre-embedded sleeves are typically manufactured in advance and then installed into the track slab mold after forming. The various stages of pre-embedded sleeve production and installation are independent of each other, lacking coordination between the different production equipment used for pre-embedded sleeves and between these equipment and the track slab production equipment. This results in cumbersome material handling and low production efficiency. Furthermore, the installation of pre-embedded sleeves is currently usually done manually, which is labor-intensive, and the installation accuracy is significantly affected by manual operation, leading to large installation quality errors and inconsistent track slab production quality.

[0031] This invention proposes a track slab production line, including a casting platform 10, a pre-embedded sleeve processing device 20, and a pre-embedded sleeve installation device 30. The casting platform 10 is provided with a transversely extending slide rail 11, on which a track slab mold 12 is slidably connected. The pre-embedded sleeve processing device 20 includes a sleeve feeding mechanism 21, a spiral rib forming mechanism 22, a cutting mechanism, a twisting mechanism 23, a first clamping mechanism 24, a second clamping mechanism 25, a first conveyor belt 26, and a second conveyor belt 27. The sleeve feeding mechanism 21... A cutting mechanism and a twisting mechanism 23 are sequentially and alternately arranged on the first conveyor belt 26. A first clamping mechanism 24 is arranged between the spiral reinforcement forming mechanism 22 and the twisting mechanism 23. A second clamping mechanism 25 is arranged between the first conveyor belt 26 and the second conveyor belt 27. A sleeve feeding mechanism 21 is used to feed sleeves onto the first conveyor belt 26. A cutting mechanism is used to cut the outer wall of the sleeve to form threads. A spiral reinforcement forming mechanism 22 is used to process the steel bars into spiral reinforcements. A first clamping mechanism 24 is used to clamp the spiral reinforcements and convey them to the twisting mechanism 25. The screwing mechanism 23 is used to screw the spiral reinforcement into the thread of the sleeve so that the spiral reinforcement is sleeved on the outside of the sleeve. The second clamping mechanism 25 is used to clamp the sleeve with the spiral reinforcement and place it on the second conveyor belt 27. The second clamping mechanism 25 can also install a fixing sleeve on the spiral reinforcement to form a pre-embedded sleeve. The pre-embedded sleeve installation device 30 includes a frame 31, a moving mechanism 32 and a third clamping mechanism 33. A casting space is formed in the frame 31. The track plate mold 12 can slide along the slide rail 11 to the casting space. Inside, the second conveyor belt 27 is located on one side of the pouring space along the longitudinal direction. The moving mechanism 32 is movably installed on the frame 31. The third clamping mechanism 33 is connected to the moving mechanism 32, and the third clamping mechanism 33 can move between the pouring platform 10 and the second conveyor belt 27 under the drive of the moving mechanism 32. When the third clamping mechanism 33 is above the second conveyor belt 27, it can clamp the embedded sleeve, and when it moves to the pouring platform 10, it can release the embedded sleeve to install the embedded sleeve in the track plate mold 12.

[0032] Please see Figure 1 and Figure 2 , Figure 1 The left and right directions in the middle are the horizontal directions. Figure 1 The front-to-back direction in the middle is the longitudinal direction. Figure 1The vertical direction is the up-down direction. The pre-embedded sleeve processing device 20 is used to process and form pre-embedded sleeves. Specifically, the sleeve feeding mechanism 21 provides sleeves to the first conveyor belt 26. The first conveyor belt 26 transmits the sleeves to the cutting mechanism. The cutting mechanism cuts the outer wall of the sleeve to form threads on the outer wall of the sleeve. Then, the first conveyor belt 26 transmits the threaded sleeve to the screwing mechanism 23. At the same time, the spiral reinforcement forming mechanism 22 is used to process the steel bars into spiral reinforcements. The first clamping mechanism 24 clamps the formed spiral reinforcements and provides them to the screwing mechanism 23. The screwing mechanism 23 screws the spiral reinforcements into the threads of the sleeve, so that the spiral reinforcements are sleeved on the outside of the sleeve. The second clamping mechanism 25 can clamp and place the sleeve with spiral ribs on the first conveyor belt 26 onto the second conveyor belt 27. The second clamping mechanism 25 can also clamp the fixed cylinder and fit the fixed cylinder around the sleeve with spiral ribs on the second conveyor belt 27, so that the fixed cylinder, spiral ribs and sleeve are fitted from the outside to the inside to form a pre-embedded sleeve. The pre-embedded sleeve installation device 30 is used to install the pre-embedded sleeve into the track plate mold 12. Specifically, the moving mechanism 32 is installed on the frame 31, and the third clamping mechanism 33 is connected to the frame 31 through the moving mechanism 32. The moving mechanism 32 can drive the third clamping mechanism 33 to move between the pouring platform 10 and the second conveyor belt 27. The third clamping mechanism 33 can clamp or release the pre-embedded sleeve. When the moving mechanism 32 moves the third clamping mechanism 33 above the second conveyor belt 27, the third clamping mechanism 33 can clamp the pre-embedded sleeve placed above the second conveyor belt 27. Then, the moving mechanism 32 moves the third clamping mechanism 33 above the track slab mold 12, aligning the pre-embedded sleeve held by the third clamping mechanism 33 with the positioning pin on the track slab mold 12, so that the pre-embedded sleeve is installed in the track slab mold 12. After installation, the third clamping mechanism 33 releases the pre-embedded sleeve. The track slab mold 12 is slidably connected to the slide rail 11, and multiple track slab molds 12 can be installed on the slide rail 11. When producing a track slab, a track slab mold 12 is slid along the slide rail 11 into the pouring space, and then the pre-embedded sleeve is installed in the track slab mold 12 through the pre-embedded sleeve installation device 30. Finally, concrete is poured into the track slab mold 12, so that the pre-embedded sleeve is embedded in the concrete, forming the track slab. After the casting of one track slab mold 12 is completed, the track slab mold 12 can be moved along the slide rail 11 to the outside of the casting space, and then the next track slab mold 12 can be moved into the casting space to produce the next track slab.

[0033] The track slab production line proposed in this invention integrates a pre-embedded sleeve processing device 20, a pre-embedded sleeve installation device 30, and a casting platform 10 into one unit, achieving integrated and automated production from pre-embedded sleeve processing and installation within the track slab mold 12 to track slab casting. The pre-embedded sleeve processing device 20 can process spiral reinforcement, cut the sleeve, fit the spiral reinforcement onto the sleeve, and fit the fixing cylinder onto the spiral reinforcement, achieving automated processing of the pre-embedded sleeve and ensuring its forming quality. The pre-embedded sleeve installation device 30 can precisely install the pre-embedded sleeve into the track slab mold 12, achieving automated installation and ensuring installation quality. The pre-embedded sleeve processing device 20 and the pre-embedded sleeve installation device 30 work together to effectively improve the production and installation efficiency of the pre-embedded sleeves. By slidably installing the track slab mold 12 on the pouring platform 10, after pouring one track slab mold 12, the track slab mold 12 can be slid out of the pouring space via the slide rail 11, so as to quickly install and pour the pre-embedded sleeve of the next track slab mold 12, realize the assembly line production of track slabs, facilitate the large-scale continuous production of track slabs, effectively improve the automation level and production efficiency of track slab production, reduce the intensity of manual labor, and improve the consistency and stability of track slab production quality.

[0034] In one embodiment, the sleeve feeding mechanism 21 includes a hopper 211 and a feeding trough 212. The hopper 211 is gradually tapered from top to bottom, and a feed port is provided at the bottom of the hopper 211. The feeding trough 212 is connected between the feed port and the first conveyor belt 26, and the bottom of the feeding trough 212 is inclined downward from the feed port to the first conveyor belt 26.

[0035] Please see Figure 5 The hopper 211 is used for stacking sleeves. The hopper 211 is gradually tapered from top to bottom, allowing the sleeves stacked in the hopper 211 to gradually slide towards the bottom feed port under the action of gravity and enter the feed trough 212. The inclined setting of the feed trough 212 allows the sleeves to slide along the feed trough 212 towards the first conveyor belt 26 under the action of gravity after exiting the feed port, ensuring smooth sliding of the sleeves. By changing the inclination angle of the feed trough 212, the sliding speed of the sleeves can be adjusted so that the feeding speed of the sleeves matches the conveying speed of the first conveyor belt 26, ensuring stable and smooth feeding of the sleeves.

[0036] In one embodiment, the spiral forming mechanism includes a winding drum 221, a straightening assembly 222, a hydraulic cutting device, a bending assembly 223, and a feeding drive unit arranged sequentially at intervals. The feeding drive unit is used to sequentially convey the reinforcing bars wound by the winding drum 221 to the straightening assembly 222, the hydraulic cutting device, and the bending assembly 223. The straightening assembly 222 includes multiple rollers 2221, which are arranged in two rows at intervals. A straightening channel for the reinforcing bars to pass through is formed between the two rows of rollers 2221. The two rows of rollers 2221 can respectively roll the upper and lower sides of the reinforcing bars to straighten them. The hydraulic cutting device is used to cut the reinforcing bars into segments, and the bending assembly 223 is used to bend the segments into spiral bars.

[0037] Please see Figure 4 The reinforcing bars are housed on the take-up drum 221. The feeding drive unit conveys the reinforcing bars to the straightening assembly 222, which straightens the reinforcing bars. The straightening assembly 222 uses two rows of rollers 2221 that rotate synchronously in opposite directions to provide multi-point support and compression for the reinforcing bars. This gradually eliminates the bending stress caused by the take-up drum 221 winding the reinforcing bars, allowing them to exit the straightening channel in a straightened state and eliminating the bending deformation that occurs when the reinforcing bars are housed on the take-up drum 221. The straightened reinforcing bars are then conveyed to the bending assembly 223 under the drive of the feeding drive unit. The ends of the reinforcing bars enter the bending assembly 223, while the middle part of the reinforcing bars passes through the hydraulic cutting device. The hydraulic cutting device cuts the continuous reinforcing bars into segments of a preset length. The bending assembly 223 bends the reinforcing bar segments at a preset bending angle to form spiral reinforcement. Through the coordinated operation of the straightening component 222, the hydraulic cutting device, the bending component 223, and the feeding drive, the spiral rib processing is automated and continuous, from the winding of the winding drum 221 to the straightening of the straightening component 222, the cutting of the hydraulic cutting device, and the bending of the bending component 223, effectively improving production efficiency.

[0038] In one embodiment, the bending assembly 223 includes a bending roller 2231, a pressure block 2232, and a servo slide. The pressure block 2232 is spaced apart from the bending roller 2231 and can swing toward or away from the bending roller 2231. The servo slide is connected to the rotating shaft of the bending roller 2231 and can drive the bending roller 2231 to rotate and slide along its axial direction.

[0039] Furthermore, the pressure block 2232 is oscillatingly positioned within the bending assembly 223. After the reinforcing bar enters the bending assembly 223, the pressure block 2232 can oscillate towards the bending roller 2231 to press the reinforcing bar tightly between the pressure block 2232 and the bending roller, causing the reinforcing bar to bend at a preset angle. Simultaneously, the servo slide drives the bending roller 2231 to slide axially, causing the reinforcing bar to bend and axially displace simultaneously, forming a spiral reinforcement. By changing the oscillation direction of the pressure block 2232, the distance between the pressure block 2232 and the bending roller 2231 is changed, thereby adjusting the bending angle of the reinforcing bar to meet the production needs of spiral reinforcement of different sizes.

[0040] In one embodiment, the twisting mechanism 23 includes a bracket, a first lifting rod, a mounting component, a lifting motor, and a twisting motor. The bracket is mounted on the first conveyor belt 26 and has a twisting channel through which the first conveyor belt 26 passes. The lifting motor is mounted on the bracket, and the movable end of the lifting motor is connected to one end of the first lifting rod. The lifting motor can drive the first lifting rod to rise and fall. The twisting motor is located at the other end of the first lifting rod, and the output shaft of the twisting motor is connected to the mounting component. The mounting component can install spiral ribs, and the twisting motor can drive the mounting component to rotate.

[0041] It should be noted that the bracket is connected to the edge of the first conveyor belt 26, so that the twisting mechanism 23 is fixedly set relative to the first conveyor belt 26, and a twisting channel is formed inside the bracket for the first conveyor belt 26 to pass through. When the first conveyor belt 26 conveys the threaded sleeve into the bracket, the mounting component clamps the spiral rib, and the lifting motor drives the first lifting rod to lower, which in turn drives the mounting component connected to the first lifting rod to lower, so that the spiral rib clamped by the mounting component contacts the sleeve. At the same time as the mounting component lowers, the twisting motor drives the mounting component to rotate, so that the spiral rib is gradually twisted into the thread, thereby putting the threaded rib on the outside of the sleeve. Through the coordinated work of the bracket, the first lifting rod, the mounting component, the lifting motor and the twisting motor, the precise twisting operation of the spiral rib is realized, ensuring that the depth and force of the twisting of the spiral rib are uniform and consistent, avoiding structural loosening or damage caused by improper twisting, effectively improving the installation accuracy of the spiral rib, and thus ensuring the forming quality of the pre-embedded sleeve.

[0042] In one embodiment, the moving mechanism 32 includes a truss 321, a tilting assembly, and a lifting assembly. A first guide rail 322 extending longitudinally is provided on the frame 31. The truss 321 is slidably connected to the first guide rail 322. A second guide rail 323 extending laterally is provided on the truss 321. The tilting assembly is slidably connected to the second guide rail 323. The lifting assembly is movably connected to the tilting assembly. A third clamping mechanism 33 is connected to the lifting assembly. The tilting assembly can move relative to the truss 321 along the second guide rail 323, and the tilting assembly can drive the lifting assembly to rotate relative to the truss 321. The lifting assembly can drive the third clamping mechanism 33 to move vertically relative to the truss 321.

[0043] Please see Figure 3 The truss 321 can slide relative to the frame 31 along the first guide rail 322, thereby driving the tilting assembly and the lifting assembly to slide longitudinally, and driving the third clamping mechanism 33 to slide longitudinally, thus realizing the longitudinal movement of the third clamping mechanism 33. The tilting assembly can slide relative to the truss 321 along the second guide rail 323, thereby driving the lifting assembly and the third clamping mechanism 33 to slide laterally, thus realizing the lateral movement of the third clamping mechanism 33. The tilting assembly can rotate relative to the truss 321, thereby driving the third clamping mechanism 33 to rotate relative to the truss 321, thus realizing the directional adjustment of the third clamping mechanism 33. The lifting assembly can drive the third clamping mechanism 33 to move vertically, thus realizing the vertical movement of the third clamping mechanism 33. Through the cooperation of the frame 31, truss 321, tilting assembly, and lifting assembly, the position and angle of the third clamping mechanism 33 can be adjusted, allowing the third clamping mechanism 33 to move between the pouring platform 10 and the second conveyor belt 27. The movement is flexible, enabling precise movement and positioning of the third clamping mechanism 33, so as to accurately clamp and release the pre-embedded sleeve.

[0044] In one embodiment, the flipping assembly includes a fixed plate, a flipping plate 324, and a flipping drive. The edge of the flipping plate 324 is hinged to the edge of the fixed plate. The flipping drive can drive the flipping plate 324 to rotate relative to the fixed plate. The side of the fixed plate away from the flipping plate 324 is slidably connected to the second guide rail 323. The side of the flipping plate 324 away from the fixed plate is movably connected to the lifting assembly.

[0045] Furthermore, the fixed plate is slidably connected to the second guide rail 323, and the fixed plate can slide along the second guide rail 323 to drive the flipping plate 324, the lifting assembly, and the third clamping mechanism 33 to move laterally together. The flipping plate 324 is hinged to the fixed plate, and the flipping drive can drive the flipping plate 324 to rotate relative to the fixed plate along the hinge axis, thereby driving the lifting assembly and the third clamping mechanism 33 to rotate, realizing the adjustment of the clamping angle and direction of the third clamping mechanism 33. It can be noted that the hinge axis between the flipping plate 324 and the fixed plate extends vertically.

[0046] In one embodiment, a snap-fit ​​block is installed on the side of the flip plate 324 away from the fixed plate. The lifting assembly includes a second lifting rod 325 and a lifting drive component. A third guide rail extending vertically is provided on the second lifting rod 325. The snap-fit ​​block is snap-fitted with the third guide rail. A third clamping mechanism 33 is connected to the bottom end of the second lifting rod 325. The lifting drive component can drive the second lifting rod 325 to slide relative to the snap-fit ​​block.

[0047] Furthermore, a third guide rail is vertically arranged along the upper edge of the second lifting rod 325. The locking block engages with and slides with the third guide rail, allowing the lifting drive component to drive the second lifting rod 325 to slide vertically relative to the locking block. The locking design between the locking block and the third guide rail not only provides precise vertical guidance for the second lifting rod 325 but also effectively limits the displacement of the second lifting rod 325 in other directions, ensuring the stability of the embedded sleeve during vertical movement. The lifting drive component drives the second lifting rod 325 to slide relative to the locking block, enabling flexible adjustment of the height of the third clamping mechanism 33.

[0048] In one embodiment, the third clamping mechanism 33 includes a cantilever beam 331 and a plurality of clamping components 332. The cantilever beam 331 is horizontally arranged, and the plurality of clamping components 332 are spaced apart on the cantilever beam 331. Each clamping component 332 includes a telescopic rod and a clamping member. The telescopic rod extends vertically, and the fixed end of the telescopic rod is connected to the cantilever beam 331. The movable end of the telescopic rod is connected to the clamping member. The telescopic rod can extend and retract to drive the clamping member connected thereto to move vertically. The clamping member can clamp or release the pre-embedded sleeve.

[0049] Please see Figure 6 Multiple clamping components 332 are spaced apart on the cantilever beam 331. When the lifting component moves the clamping components 332 vertically, the multiple clamping components 332 can move synchronously and approach the pre-embedded sleeves simultaneously, so that multiple pre-embedded sleeves can be clamped by multiple clamping parts, thereby realizing the synchronous installation of multiple pre-embedded sleeves into the mold. Each telescopic rod extends vertically, and each telescopic rod drives the clamping parts connected to it to move vertically through telescopic movement, so that each clamping component 332 can adjust each clamping part individually. The height of the clamping part can be adjusted according to the different sizes of the pre-embedded sleeves, so that each clamping part can accurately clamp the corresponding pre-embedded sleeve. The clamping components 332 can clamp multiple pre-embedded sleeves of different sizes at the same time, effectively improving the versatility and adaptability of the mold-entry device. The lifting assembly can adjust the overall height of the clamping assembly 332 over a wide range, and each telescopic rod can make fine adjustments to the height of its corresponding clamping component. The cooperation between the lifting assembly and multiple telescopic rods can achieve multi-gradient adjustment of the clamping component's height, improving the height adjustment speed of the clamping component while ensuring adjustment accuracy.

[0050] In one embodiment, the clamping member includes a connecting plate 3321, a clamping drive member, and a plurality of clamping claws 3322. The connecting plate 3321 is connected to the movable end of the telescopic rod. The plurality of clamping claws 3322 are all disposed on the side of the connecting plate 3321 away from the telescopic rod, and the plurality of clamping claws 3322 are spaced apart. The clamping drive member can drive the plurality of clamping claws 3322 to move closer or further away from each other, so as to clamp or release the pre-embedded sleeve accordingly.

[0051] Understandably, multiple clamping jaws 3322 are spaced apart on the connecting plate 3321. The clamping drive can drive the multiple clamping jaws 3322 to move closer together to jointly clamp the pre-embedded sleeve, and the clamping drive can also drive the multiple clamping jaws 3322 to move further apart to loosen the pre-embedded sleeve. By driving the multiple clamping jaws 3322 to move, the clamping components can be automatically controlled, and the clamping force of the clamping components on the pre-embedded sleeve can be controlled to ensure that the pre-embedded sleeve is firmly clamped while avoiding damage to the pre-embedded sleeve.
