Abstract
Description
Technical Field
[0001] This invention belongs to the field of municipal road construction technology, specifically relating to a curbstone paving equipment. Background Technology
[0002] With the development of urban construction, the requirements for municipal pavements are becoming increasingly stringent. Sidewalks, squares, and other areas typically require large areas to be paved with smooth paving stones and curbs. Currently, the laying of paving stones and curbs is generally done manually or using a combination of machinery and manual labor. The combined manual and mechanical method involves using a crane to lift the bricks with ropes, then manually controlling the drop point before unloading the bricks, and finally compacting them. This method is time-consuming and labor-intensive, the laying effect depends heavily on the skill level of the workers, and requires a large workforce, thus increasing the laying cost.
[0003] The prior art, publication number CN113737617B, discloses an integrated flatbed truck and method for short-distance loading and unloading of curb stones. The integrated flatbed truck for short-distance loading and unloading of curb stones includes a vehicle body, tracks, a transmission device, a moving device, and an unloading device. Tracks are rolled on the vehicle body, and a moving device is rotatably connected to the bottom of the vehicle body. The moving device is connected to the tracks through the transmission device. The movement of the moving device drives the transmission of the tracks. An unloading device is provided on the left side of the vehicle body. The flatbed truck is used as a power source to unload curb stones while moving, realizing the direct and precise positioning and unloading of curb stones one by one into the excavation trench.
[0004] Publication No. CN111188247A discloses a road curbstone installation device, including a traveling support plate, traveling wheels, a limiting mechanism, a fixed plate, a sliding plate, a sliding spring, a spring support plate, and a pushing mechanism. The traveling support plate has traveling wheels symmetrically installed on its bottom. The limiting mechanism is installed on the top left end of the traveling support plate. The fixed plate is connected to the top of the traveling support plate. A sliding groove is provided laterally on the top right end of the traveling support plate. The sliding groove of the traveling support plate is connected to the sliding plate by a sliding fit. The right side of the sliding plate is connected to the spring support plate by a sliding spring. The spring support plate is installed on the top right end of the traveling support plate. The pushing mechanism is installed on the top rear end of the traveling support plate.
[0005] Both of the technical solutions described in the above two publicly available documents can complete the output of curb stones one by one, but neither can guarantee the spacing between the curb stones after they are placed on the ground. The gap width between the curb stones is 5mm, and the above existing technologies cannot precisely control the 5mm spacing. In addition, the curb stones need to be neatly arranged on the vehicle and aligned in a row for stable output. Using the above equipment may reduce the burden in the curb stone installation stage, but it increases the workload in the construction preparation stage, and the overall work efficiency is not improved much. Summary of the Invention
[0006] This invention addresses the problem that existing curbstone installation equipment struggles to precisely control the installation spacing of curbstones, and requires the curbstones to be arranged neatly when loaded, resulting in a large workload during the construction preparation phase.
[0007] The present invention provides the following technical solution: a curbstone laying equipment, including a chassis, on which a curbstone storage platform, a curbstone conveying line, a curbstone arrangement mechanism and a curbstone output device are mounted;
[0008] The curbstone storage platform includes a lateral pushing component, a longitudinal pushing component, and a support platform consisting of several ball bearing arrays. One side of the support platform is used as a loading port, and the other side is connected to the curbstone conveyor line. A positioning part is provided on the side connected to the curbstone conveyor line. The lateral pushing component and the longitudinal pushing component are used to push the curbstone to slide on the support platform. After the curbstone is against the positioning part, it is pushed onto the curbstone conveyor line in a parallel posture with the positioning part.
[0009] The curbstone conveyor line is used to transport curbstones in a fixed position to the curbstone output device;
[0010] The curbstone arrangement mechanism is installed on the curbstone conveyor line to arrange n curbstones that have arrived at the curbstone output device at a specified interval, where n is an integer ≥ 2;
[0011] The curbstone output device extends outward from the side of the chassis in the direction of travel, so that its outlet can be aligned with the curbstone installation groove. The curbstone output device outputs n curbstones arranged by the curbstone arrangement mechanism into the curbstone installation groove, based on the paved curbstone.
[0012] Furthermore, the longitudinal pushing assembly includes a conveyor chain and a spring pusher. The conveyor chain is installed between the rows of balls and below the ball support plane. The spring pusher is installed on a link of the conveyor chain and extends from the ball support plane. The thrust required for the spring pusher to flex is greater than the resistance when the curb moves on the support platform. Driven by the conveyor chain, the spring pusher pushes the curb. When the curb reaches the end point and is obstructed, the spring pusher flexes and resets from the bottom surface of the curb.
[0013] The lateral pushing assembly includes a first screw mechanism and a first push plate, the first push plate pushing the curb stone under the drive of the first screw mechanism;
[0014] The longitudinal pushing component is divided into a forward pushing part and a backward pushing part. The forward pushing part is used to push the entire row of curb stones in the direction of the feeding port into the working range of the transverse pushing component. The backward pushing part can only push a single curb stone. The transverse pushing component pushes the entire row of curb stones to the backward pushing part. The positioning part is used to limit the pushed curb stones. The backward pushing part pushes the curb stones one by one onto the curb stone conveyor line.
[0015] Furthermore, the curbstone conveyor line includes a curbstone shifting mechanism, bidirectional rollers, and a conveyor roller. Several bidirectional rollers are coaxially mounted and arranged in a line along the conveying direction. Rollers with rotation directions perpendicular to the rollers are evenly arranged on the circumference of the roller body. The coaxial bidirectional rollers are driven to rotate synchronously by their respective shafts, and the rollers rotate freely on the roller body. The bidirectional rollers form a first bidirectional conveyor line and a second bidirectional conveyor line. The first bidirectional conveyor line is connected to the support platform, and the conveyor roller is located between the first bidirectional conveyor line and the second bidirectional conveyor line. Only one curbstone is allowed to pass through the first bidirectional conveyor line, the second bidirectional conveyor line, and the conveyor roller. The curbstone shifting mechanism is used to shift the curbstones on the first bidirectional conveyor line to the second bidirectional conveyor line via the conveyor roller.
[0016] Furthermore, the curbstone output device includes a pushing mechanism, a transition platform, a release mechanism, a limiting plate, a frame, and a curbstone positioning ruler. The transition platform is aligned with the second bidirectional conveyor line and consists of rollers, with the conveying direction perpendicular to the second bidirectional conveyor line. The frame is installed at the cantilevered end of the transition platform, and the gap between the frame and the transition platform serves as the curbstone output port. The limiting plate is installed on the frame and extends into the transition platform, and the limiting plate is aligned with the spacing of the curbstones arranged by the curbstone arrangement mechanism. The release mechanism is installed on the frame and is used to close or open the curbstone output port. The pushing mechanism is installed on the side of the second bidirectional conveyor line and is used to push the curbstones on the second bidirectional conveyor line to the curbstone output port. The curbstone positioning ruler is installed below the curbstone output port and is aligned with the limiting plate. The curbstone positioning ruler includes two perpendicular ruler plates. The thickness of the first ruler plate is equal to the curbstone paving spacing, and the second ruler plate is used to fit against the side of the curbstone to determine its paving line.
[0017] Furthermore, the release mechanism includes a gate, a trigger slide plate, a movable pulley, and a pull rope; the gate and the trigger slide plate are parallel and slidably inserted into the frame, the top surface of the gate is flush with the support surface of the transition platform, and the trigger slide plate is located above the gate; the movable pulley is installed on the trigger slide plate, one end of the pull rope is connected to the frame, and the other end passes around the movable pulley and connects to the gate; when the gate closes the curb stone outlet, the trigger slide plate closes 1 / 2 of the curb stone outlet; the gate is connected to a reset spring.
[0018] Furthermore, the curbstone arrangement mechanism includes a first limiting component, a second limiting component, ... an m-th limiting component. The m limiting components are equidistantly distributed along the conveying direction of the second bidirectional conveyor line, with the spacing equal to the length of a single curbstone, and m equal to the number of curbstones arranged in a single operation.
[0019] Each of the m limiting components includes a swing frame and a linear push rod. The swing frame includes a baffle and a pry bar that are fixedly connected at an angle. The apex of the swing frame is hinged to the support member. The baffle is on top and can be rotated into the second bidirectional conveyor line above. The pry bar is on the bottom and has an elongated hole. The linear push rod is slidably inserted into the transverse guide hole, and the pin at its end is slidably fitted into the elongated hole of the pry bar.
[0020] The swing arm of the first limiting component is connected to a spring, which pushes the swing arm to make the pry bar vertical, and the pin of the linear push rod is located in the middle of the elongated hole.
[0021] The second limiting component and the m-th limiting component have the same structure, and also include a locking hook. The bottom end of the locking hook is hinged to the supporting member. A tension spring is connected to the locking hook. The tension spring pulls the locking hook to rotate toward the swing frame so that the hook body hooks onto the baffle of the swing frame. A torsion spring is connected to the swing frame. The torsion spring pushes the swing frame to maintain an upward springing tendency. The linear push rod of the first limiting component is used to trigger the locking hook of the second limiting component. The linear push rod of the second limiting component is used to trigger the locking hook of the third limiting component, and so on. The linear push rod of the (m-1)-th limiting component is used to trigger the locking hook of the m-th limiting component.
[0022] The thickness of the baffle is equal to the paving spacing of the curbstones. After the first curbstone pushes the swing frame of the first limiting component to rotate until the baffle is upright, the swing frame of the second limiting component is unlocked and the swing frame pops up. After the second curbstone pushes the swing frame of the second limiting component to rotate until the baffle is upright, the swing frame of the third limiting component is unlocked and the swing frame pops up, and so on.
[0023] It also includes a limit component reset mechanism, which includes a comb frame. The crossbar of the comb frame is slidably mounted in the transverse guide hole, and the vertical bar corresponds one-to-one with the swing frame of the second limit component to the m-th limit component. When the comb frame moves laterally, it pushes the swing frame to reset.
[0024] Furthermore, the spacing between the limit plates on the frame is adjustable; the limit plates are slidably installed in the guide groove of the frame, and several limit plates are connected to the same variable lead screw. The first limit plate is helically engaged with the first segment of the screw, the second limit plate is helically engaged with the second segment of the screw, the third limit plate is helically engaged with the third segment of the screw, and so on. The lead of the second segment is twice that of the first segment, the lead of the third segment is three times that of the first segment, and so on.
[0025] The spacing between the limiting components changes synchronously with the limiting plate; the first limiting component is fixed, the second limiting component is installed on the first limiting plate, the third limiting component is installed on the second limiting plate, and so on, with the m-th limiting component installed on the (m-1)-th limiting plate;
[0026] The linear push rod of the limiting component includes a first inner tube and a first outer tube that are inserted into each other. A first locking sleeve is connected between the first inner tube and the first outer tube. When the first locking sleeve is loosened, the first inner tube can be freely extended from the first outer tube. When the first locking sleeve is tightened, the first inner tube is fixed.
[0027] The crossbar between the two vertical bars on the comb frame includes a second inner tube and a second outer tube that are inserted into each other. A second locking sleeve is connected between the second inner tube and the second outer tube. When the second locking sleeve is loosened, the second inner tube can be freely extended from the second outer tube. When the second locking sleeve is tightened, the second inner tube is fixed.
[0028] Furthermore, the transverse guide hole of the crossbar of the comb frame can slide vertically, the limiting plate is provided with a slot, and the vertical bar of the comb frame is connected with a hook. After the comb frame falls, the hook is engaged in the slot, unlocking the second locking sleeve. The crossbar of the comb frame extends or shortens as the limiting plate moves. After the comb frame is lifted, the hook separates from the slot.
[0029] The first inner tube has a 90° circumferential notch. A pin connected to the first locking sleeve extends into the notch. The end of the first inner tube is provided with two support ears. The first locking sleeve has a 180° travel for loosening and tightening. The limiting plate is provided with a corresponding slot for the support ears. The slot has a through groove that allows the support ears to pass laterally. When the first locking sleeve is loosened and rotated, the pin first passes through the notch and then pushes the edge of the notch to make the first inner tube rotate. The first inner tube rotates 90° and the support ears are engaged in the slot. The linear push rod extends or shortens as the limiting plate moves. When the first locking sleeve is tightened and rotated, the pin first passes through the notch and then pushes the edge of the notch to make the first inner tube rotate. The first inner tube rotates 90° and the support ears are aligned with the through groove of the slot. After the length of the linear push rod is fixed, it can pass through the slot to trigger the locking hook.
[0030] Furthermore, the jacking mechanism includes a second push plate and a cylinder. The cylinder barrel is fixed on the chassis, and the push plate is mounted on the cylinder rod. The cylinder pushes the push plate out to push the curb stone.
[0031] Furthermore, the running chassis is a tracked vehicle chassis.
[0032] Compared with the prior art, the advantages of the present invention are:
[0033] This invention provides a curbstone paving equipment, in which a chassis carries a curbstone storage platform, a curbstone conveyor line, a curbstone arrangement mechanism, and a curbstone output device, moving along the curbstone paving route. The curbstone storage platform can store multiple curbstones at a time for continuous paving. When placing curbstones on the curbstone storage platform, it is not necessary to precisely adjust the posture of the curbstones. When the curbstone storage platform outputs curbstones to the curbstone conveyor line, it can automatically adjust the curbstones to a uniform posture, saving preparation time.
[0034] The curbstone conveyor line delivers one curbstone at a time, continuously and stably supplying curbstones to the curbstone output device. At the end of the curbstone conveyor line, the curbstone arranging mechanism can arrange the curbstones sequentially at a specified interval, which is the curbstone paving spacing. After the arrangement is completed, the curbstones are pushed into the curbstone output device, and then the curbstone output device releases the entire row of curbstones into the curbstone installation trench at once.

[0057] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0058] like Figure 1 , Figure 2 The image shows a curbstone paving equipment, including a tracked chassis 1. Tracked chassis offer advantages such as high load-bearing capacity, minimal impact from road surface unevenness, and stable travel path. The chassis 1 is equipped with a curbstone storage platform 6, a curbstone conveyor line 4, a curbstone arrangement mechanism 7, and a curbstone output device 5. Specifically, the curbstone storage platform 6 is located at one end of the chassis 1 in the direction of travel, facilitating the loading and unloading of curbstones, allowing for the loading of curbstones at any time during the paving process. The curbstone conveyor line 4 and the curbstone arrangement mechanism 7 are located on the side of the chassis 1 in the direction of travel, meaning the curbstone output device 5 is parallel to the curbstone installation groove.
[0059] like Figure 2 As shown: The curbstone storage platform 6 includes a lateral pushing component 6.2, a longitudinal pushing component, and a support platform 6.1 consisting of several ball bearing arrays. The curbstones are supported by the ball bearings and can slide and rotate freely, facilitating attitude adjustment and position movement. One side of the support platform 6.1 serves as a loading port, and the other side is connected to the curbstone conveyor line 4. The loading port is located at the edge of the traveling chassis 1. A positioning part 6.5 is provided on the side connected to the curbstone conveyor line 4. The positioning part 6.5 is a retaining wall parallel to the curbstone installation groove. The lateral pushing component 6.2 and the longitudinal pushing component are used to push the curbstones to slide on the support platform 6.1. After the curbstones come into contact with the positioning part 6.5, they are pushed onto the curbstone conveyor line 4 in an attitude parallel to the positioning part 6.5.
[0060] The curbstone conveyor line 4 is used to convey curbstones in a fixed position to the curbstone output device 5.
[0061] The curbstone arrangement mechanism 7 is installed on the curbstone conveyor line 4 and is used to arrange n curbstones arriving at the curbstone output device 5 at a specified interval, where n is an integer ≥ 2. In this embodiment, n is 3, and the curbstone laying equipment in this embodiment lays 3 curbstones at a time.
[0062] The curbstone output device 5 extends out from the side of the traveling chassis 1 in the direction of travel, so that its outlet can be aligned with the curbstone installation groove; the curbstone output device 5 outputs the three curbstones arranged by the curbstone arrangement mechanism 7 into the curbstone installation groove based on the paved curbstone.
[0063] like Figure 3 , Figure 4 As shown: The longitudinal pushing assembly includes a conveyor chain 6.3 and a spring push rod 6.4. The conveyor chain 6.3 is installed between the ball bearing rows and below the ball bearing support plane. The conveyor chain 6.3 does not affect the sliding of the curbstone. The spring push rod 6.4 is installed on a link of the conveyor chain 6.3 and extends from the ball bearing support plane. The thrust required for the spring push rod 6.4 to flex is greater than the resistance when the curbstone moves on the support platform 6.1. Driven by the conveyor chain 6.3, the spring push rod 6.4 pushes the curbstone. When the curbstone reaches the end point and is obstructed, the spring push rod 6.4 flexes and resets from the bottom surface of the curbstone.
[0064] The lateral pushing assembly 6.2 includes a first screw mechanism and a first push plate, the first push plate pushing the curb stone under the drive of the first screw mechanism.
[0065] The longitudinal pushing component is divided into a forward pushing part and a backward pushing part. The forward pushing part is used to push the entire row of curb stones in the direction of the feeding port into the working range of the transverse pushing component 6.2. The backward pushing part can only push a single curb stone. The transverse pushing component 6.2 pushes the entire row of curb stones to the backward pushing part. The positioning part 6.5 is used to limit the pushed curb stones. The backward pushing part pushes the curb stones one by one onto the curb stone conveyor line 4.
[0066] After the curbstones are placed on the curbstone storage platform 6, their movement path is as follows: First, the entire row of curbstones is loaded onto the support platform 6.1 by mechanical equipment. Then, the forward pushing part pushes the entire row of curbstones from the loading port to the lateral pushing component 6.2. When the curbstones reach the position of the lateral pushing component 6.2 (one edge of the support platform 6.1), their movement is hindered. Due to the excessive resistance, the spring push rod 6.4 flexes and slides across the bottom surface of the curbstones, moving back to the loading port for the next push. The first screw mechanism drives the first push plate to move the entire row of curbstones towards the positioning part 6.5 (the backward pushing part). Considering that it is difficult to make the curbstones parallel to the curbstone laying route when the mechanical equipment is placed on the support platform 6.1, the first push plate continues to push the curbstones when they approach the positioning part 6.5, bringing them close to the positioning part 6.5 until they are parallel to it. Then, the backward pushing part pushes the curbstones one by one into the curbstone conveyor line 4.
[0067] like Figure 5 As shown: The curbstone conveyor line 4 includes a curbstone shifting mechanism 4.1, bidirectional rollers 4.3, and a conveyor roller 4.2. Several bidirectional rollers 4.3 are coaxially mounted and arranged in a line along the conveying direction. Rollers perpendicular to the rotation direction are evenly arranged on the circumference of the wheel body of the bidirectional rollers 4.3. The coaxial bidirectional rollers 4.3 are driven to rotate synchronously by their respective shafts, and the rollers rotate freely on the wheel body. The bidirectional rollers 4.3 form a first bidirectional conveyor line 4.4 and a second bidirectional conveyor line 4.5. The first bidirectional conveyor line 4.4 is connected to the support platform 6.1. The conveyor roller 4.2 is located between the first bidirectional conveyor line 4.4 and the second bidirectional conveyor line 4.5. Only one curbstone is allowed to pass through each of the first bidirectional conveyor line 4.4, the second bidirectional conveyor line 4.5, and the conveyor roller 4.2. The curbstone shifting mechanism 4.1 is used to shift the curbstones on the first bidirectional conveyor line 4.4 to the second bidirectional conveyor line 4.5 via the conveyor roller 4.2.
[0068] Each bidirectional roller 4.3 includes two parallel single rollers with staggered rollers to ensure smooth movement of the curbstone.
[0069] like Figure 6As shown: The curbstone output device 5 includes a pushing mechanism 5.5, a transition platform 5.3, a release mechanism 5.4, a limiting plate 5.2, a frame 5.1, and a curbstone positioning ruler 5.6; the transition platform 5.3 is aligned with the second bidirectional conveyor line 4.5, and the transition platform 5.3 is composed of rollers, with the conveying direction perpendicular to the second bidirectional conveyor line 4.5; the frame 5.1 is installed at the cantilevered end of the transition platform 5.3, and the gap between the frame 5.1 and the transition platform 5.3 serves as the curbstone output port; the limiting plate 5.2 is installed on the frame 5.1 and extends into the transition platform 5.3, and the limiting plate 5.2 is aligned with the curbstone arrangement mechanism 7 after arrangement. The curbstone spacing is aligned, and the limiting plate 5.2 is used to limit the posture of the curbstone to prevent it from tilting; the release mechanism 5.4 is installed on the frame 5.1 to close or open the curbstone output port; the pushing mechanism 5.5 is installed on the side of the second bidirectional conveyor line 4.5 to push the curbstone on the second bidirectional conveyor line 4.5 to the curbstone output port; the curbstone positioning ruler 5.6 is installed below the curbstone output port and is aligned with the limiting plate 5.2 one by one. The curbstone positioning ruler 5.6 includes two perpendicular ruler plates. The thickness of the first ruler plate is equal to the curbstone paving spacing, and the second ruler plate is used to fit against the side of the curbstone to determine its paving line.
[0070] Specifically, the jacking mechanism 5.5 includes a second push plate and a cylinder. The cylinder barrel is fixed on the traveling chassis 1, and the push plate is mounted on the cylinder rod. The cylinder pushes the push plate out to push the curb stone.
[0071] like Figure 7 , Figure 8As shown: To ensure the curbstone leaves the curbstone output device 5 in a vertical position and prevent the curbstone from tilting during output, the release mechanism 5.4 includes a gate 5.4.4, a trigger slide 5.4.2, a movable pulley 5.4.3, and a pull rope 5.4.6. The gate 5.4.4 and the trigger slide 5.4.2 are parallel and slidably inserted into the frame 5.1. The top surface of the gate 5.4.4 is flush with the support surface of the transition platform 5.3, and the trigger slide 5.4.2 is located above the gate 5.4.4. The movable pulley 5.4.3 is installed on the trigger slide 5.4.2. One end of the pull rope 5.4.6 is connected to the frame 5.1, and the other end passes around the movable pulley 5.4.3 and connects to the gate 5.4.4. When the gate 5.4.4 closes the curbstone output port, the trigger slide 5.4.6 is activated. 4.2 Close half of the curbstone outlet; after the trigger slide 5.4.2 and the gate 5.4.4 are connected by a movable pulley 5.4.3 and a pull rope 5.4.6, the stroke of the gate 5.4.4 is twice that of the trigger slide 5.4.2. When the curbstone contacts the trigger slide 5.4.2, half of it is on the transition platform 5.3 and half is on the gate 5.4.4. The curbstone continues to push the trigger slide 5.4.2, and the trigger slide 5.4.2 and the gate 5.4.4 retract simultaneously until the gate 5.4.4 is fully retracted. The curbstone instantly detaches from the curbstone outlet and falls into the curbstone installation groove. The gate 5.4.4 is connected to a return spring 5.4.5. After the curbstone detaches, the return spring 5.4.5 pushes the trigger slide 5.4.2 and the gate 5.4.4 to reset.
[0072] like Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown: The curbstone arrangement mechanism 7 includes a first limiting component 7.1, a second limiting component 7.2, and a third limiting component 7.8. The three limiting components are equidistantly distributed along the conveying direction of the second bidirectional conveyor line 4.5, and the spacing is equal to the length of a single curbstone.
[0073] All three limiting components include a swing frame and a linear push rod 7.3. The swing frame includes a baffle 7.4 and a pry bar 7.5 fixedly connected at an angle. The apex of the swing frame is hinged to the support member. The baffle 7.4 is on top and can be rotated into the second bidirectional conveyor line 4.5 above. The pry bar 7.5 is on the bottom and has an elongated hole. The linear push rod 7.3 is slidably inserted into the transverse guide hole, and the pin at its end is slidably fitted into the elongated hole of the pry bar 7.5.
[0074] The first limiting component 7.1 is located at the end of the second bidirectional conveyor line 4.5. The swing frame of the first limiting component 7.1 is connected to a spring. The spring pushes the swing frame to make the pry bar 7.5 vertical. The pin of the linear push rod 7.3 is located in the middle of the elongated hole.
[0075] The second limiting component 7.2 and the third limiting component 7.8 have the same structure and also include a locking hook 7.6. The bottom end of the locking hook 7.6 is hinged to the supporting member. A tension spring is connected to the locking hook 7.6. The tension spring pulls the locking hook 7.6 to rotate toward the swing frame so that the hook body hooks the baffle 7.4 of the swing frame. A torsion spring is connected to the swing frame. The torsion spring pushes the swing frame to maintain an upward springing tendency. In the first state, the locking hook 7.6 hooks the swing frame and the baffle 7.4 is located below the second bidirectional conveyor line 4.5. In the second state, the locking hook 7.6 releases the swing frame and the baffle 7.4 is located above the second bidirectional conveyor line 4.5. When the curbstone arrives, the baffle 7.4 is sandwiched between the two curbstones to determine the distance between the curbstones. The linear push rod 7.3 of the first limiting component 7.1 is used to trigger the locking hook 7.6 of the second limiting component 7.2. The linear push rod 7.3 of the second limiting component 7.2 is used to trigger the locking hook 7.6 of the third limiting component 7.8. That is, when the curb pushes the swing frame to rotate, the pry bar 7.5 pushes the linear push rod 7.3 to move, and the swing frame on the first limiting component is unlocked.
[0076] The thickness of the baffle 7.4 is equal to the paving spacing of the curbstones. After the first curbstone pushes the swing frame of the first limiting component 7.1 to rotate until the baffle 7.4 is erected, the swing frame of the second limiting component 7.2 is unlocked and the swing frame pops up. After the second curbstone pushes the swing frame of the second limiting component 7.2 to rotate until the baffle 7.4 is erected, the swing frame of the third limiting component 7.8 is unlocked and the swing frame pops up.
[0077] It also includes a limit component reset mechanism, which comprises a comb frame 7.7. The horizontal bar of the comb frame 7.7 is slidably mounted in the horizontal guide hole, and the vertical bar corresponds one-to-one with the swing frames of the second limit component 7.2 and the third limit component 7.8. When the comb frame 7.7 moves laterally, it pushes the swing frame to reset. When the comb frame 7.7 moves laterally, the vertical bar causes the swing frame to rotate, the baffle 7.4 presses down to push open the locking hook 7.6, so that the baffle 7.4 is engaged in the locking hook 7.6, and then the comb frame 7.7 resets. The movement of the comb frame 7.7 can be driven by an electric push rod behind a cylinder.
[0078] like Figure 13 , Figure 14 As shown: The spacing between the limiting plates 5.2 on the frame 5.1 is adjustable; the limiting plates 5.2 are slidably installed in the guide groove of the frame 5.1, and several limiting plates 5.2 are connected to the same variable lead screw 8. The first limiting plate is helically engaged with the first segment of the screw 8, the second limiting plate is helically engaged with the second segment of the screw 8, and the third limiting plate is helically engaged with the third segment of the screw 8. The lead of the second segment is twice that of the first segment, and the lead of the third segment is three times that of the first segment. In this way, the spacing between the limiting plates changes proportionally to adapt to curb stones of different lengths; the screw 8 can be rotated manually or driven by a servo motor.
[0079] The spacing between the limiting components changes synchronously with the limiting plate 5.2; the first limiting component 7.1 is fixed, the second limiting component 7.2 is mounted on the first limiting plate, and the third limiting component 7.8 is mounted on the second limiting plate. It should be noted that the second limiting component 7.2 and the third limiting component 7.8 are mounted between the axes of the bidirectional roller 4.3; therefore, the limiting plate 5.2 can only move within the range of the axis spacing of the bidirectional roller 4.3.
[0080] The linear push rod 7.3 of the limiting assembly includes a first inner tube 7.3.1 and a first outer tube 7.3.2 that are inserted into each other. A first locking sleeve 7.3.3 is connected between the first inner tube 7.3.1 and the first outer tube 7.3.2. When the first locking sleeve 7.3.3 is loosened, the first inner tube 7.3.1 can be freely extended from the first outer tube 7.3.2. When the first locking sleeve 7.3.3 is tightened, the first inner tube 7.3.1 is fixed.
[0081] The crossbar between the two vertical bars on the comb frame 7.7 includes a second inner tube and a second outer tube that are inserted into each other. A second locking sleeve is connected between the second inner tube and the second outer tube. When the second locking sleeve is loosened, the second inner tube can be freely extended from the second outer tube. When the second locking sleeve is tightened, the second inner tube is fixed.
[0082] like Figure 14 , Figure 15 , Figure 16 As shown: the horizontal guide hole of the horizontal bar of the comb frame 7.7 can slide vertically. The limiting plate 5.2 is provided with a slot 5.2.1. The vertical bar of the comb frame 7.7 is connected to a hook 7.7.1. After the comb frame 7.7 falls, the hook 7.7.1 is engaged in the slot 5.2.1, unlocking the second locking sleeve. The horizontal bar of the comb frame 7.7 extends or shortens as the limiting plate 5.2 moves. After the comb frame 7.7 is lifted, the hook 7.7.1 separates from the slot 5.2.1.
[0083] The first inner tube 7.3.1 has a 90° circumferential notch 7.3.1.1. The pin 7.3.3.1 connected to the first locking sleeve 7.3.3 extends into the notch 7.3.1.1. The end of the first inner tube 7.3.1 is provided with two support ears 7.3.1.2. The first locking sleeve 7.3.3 has a 180° travel for loosening and tightening. The limiting plate 5.2 has a corresponding retainer 5.2.2, which has a through groove that allows the support ears 7.3.1.2 to pass laterally. When the first locking sleeve 7.3.3 is loosened and rotated, the pin 7.3.3.1 first passes through the notch 7.3.3. 1.1 Then push the edge of the notch to rotate the first inner tube 7.3.1. The first inner tube 7.3.1 rotates 90° and the supporting ear 7.3.1.2 is inserted into the card seat 5.2.2. The linear push rod 7.3 extends or shortens as the limiting plate 5.2 moves. When the first locking sleeve 7.3.3 is tightened and rotated, the pin 7.3.3.1 first passes through the notch 7.3.1.1 and then pushes the edge of the notch to rotate the first inner tube 7.3.1. The first inner tube 7.3.1 rotates 90° and the supporting ear 7.3.1.2 is aligned with the through groove of the card seat 5.2.2. After the length of the linear push rod 7.3 is fixed, it can pass through the card seat 5.2.2 to trigger the locking hook 7.6.
