Description

Technical Field

[0001] This invention relates to the field of road construction, and more particularly to a construction equipment for road construction. Background Technology

[0002] Highway guardrails are primarily designed to effectively cushion and absorb shocks from vehicles during accidents, reducing injuries to occupants. They typically consist of posts and guardrail panels. Posts are driven into the ground using a pile driver, and the guardrail panels are then installed manually. Chinese patent application number CN202011134996.7 describes a highway guardrail installation device and its usage method. This device replaces manual labor by moving the guardrail to the connection point between the guardrail and the posts. Workers only need to fix the connection, significantly reducing manpower. The device includes torsion springs and angle adjustment mechanisms to fine-tune the front-to-back and vertical distances between the guardrail and the posts. However, this device cannot install guardrail panels on curves, which are often the most difficult areas, requiring three to four workers to bend and install the panels simultaneously. During this bending process, there is a risk of the guardrail slipping from workers' hands, potentially causing injury and posing a threat to their safety.

[0003] Meanwhile, during the bending process of the guardrail, the posts are easily bent by the guardrail, resulting in the installation angle of the posts not conforming to specifications, reducing the buffering and shock absorption effect of the guardrail. Secondly, the device cannot be adapted to the installation of guardrails of different lengths, resulting in poor adaptability. It is limited to the installation of guardrails of specified dimensions, which greatly reduces the adaptability of the device to guardrail installation. At the same time, the device is not convenient and occupies a large area, which means that it needs to be installed in road sections with high traffic volume, affecting the normal operation of traffic. Summary of the Invention

[0004] To overcome the shortcomings of existing devices that cannot install guardrails on curves, which can easily injure workers when the guardrails are bent, and whose posts can easily be tilted by the guardrails, affecting their cushioning and shock absorption effects, and which existing devices cannot be adapted to guardrails of different lengths, this invention provides a construction equipment for road construction.

[0007] Furthermore, preferably, the bending assembly includes a second connecting rod, a first pulley, an electric rotating rod, a second connecting plate, a first connecting rod, and a third connecting plate; the electric rotating rod is fixedly connected to the upper side of the slide plate; the second connecting plate is rotatably connected to the upper side of the slide plate; the end of the second connecting plate away from the slide plate is fixedly connected to an adjacent limiting block; a first connecting rod that reduces the backward tilt of the post during the bending process of the guardrail is rotatably connected to the left side of the second connecting plate; the middle part of the first connecting rod is rotatably connected to the rear side of the slide plate; the end of the first connecting rod away from the second connecting plate is rotatably connected to the third connecting plate; the upper side of the third connecting plate is fixedly connected to an adjacent limiting block; the second connecting rod is fixedly connected to the lower side of the third connecting plate; the end of the second connecting rod away from the third connecting plate is movably connected to the slide plate; and several first pulleys that reduce the friction between the slide plate and the concrete road surface are rotatably connected to the lower side of the slide plate.

[0008] Furthermore, it is particularly preferred that the connecting assembly includes a steel rope, a lock, and a top rod; a steel rope to prevent the column from tilting is wound around the outer surface of the electric rotating rod; a lock is fixed to the end of the steel rope away from the electric rotating rod; the steel rope is wound in an S-shape around all the stops; and a top rod is connected to the rear side of the fixing plate by a spring.

[0009] Furthermore, it is particularly preferred that the limiting block is configured in an arc shape that fits into the grooves on the front and rear sides of the guardrail.

[0010] Furthermore, it is particularly preferred that the lower side of the first connecting plate is serrated.

[0011] In addition, it is particularly preferred that the system also includes a cleaning system, which includes a cleaning block, an inclined plate, a second pulley, and a compaction wheel; a cleaning block for cleaning the mud on the side of the cement road is fixed to the right side of the sliding plate; an inclined plate for guiding the mud to move up and down is fixed to the right side of the cleaning block; several second pulleys are rotatably connected to the front of the cleaning block; and several compaction wheels for compacting the mud are rotatably connected to the lower side of the cleaning block.

The downward-sloping plate guides the soil on the lower side toward the extrusion wheel, and the extrusion wheel compacts the soil, improving the device's fixation effect on the column. The pressure sensor detects excessive or insufficient pressure and triggers an alarm, which then notifies the workers that the column has tilted significantly, prompting them to take timely action to ensure the continued use of the guardrail. By passing the locking rod through the threaded holes on the upper left and lower left sides of the guardrail, the bolts are prevented from slipping and loosening during the bending of the guardrail, thus ensuring the buffering effect of the guardrail in the later stage.

Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention. Example

[0019] like Figures 3-5 As shown, a construction device for road construction includes a column 1, a guardrail 2, a fixing plate 4, and a sliding plate 5; two columns 1 are provided, and a guardrail 2 is installed on the front side of both columns 1; a fixing plate 4 is provided on the front side of the column 1 on the left; a sliding plate 5 is provided on the front side of the guardrail 2, and the sliding plate 5 is located to the right of the fixing plate 4. It also includes a fixing component, a bending component, a limiting block 3, and a connecting component; the fixing component is installed on the fixing plate 4; the bending component is installed on the sliding plate 5; the bending component is equipped with three limiting blocks 3; the fixing component is equipped with two more limiting blocks 3; the bending component is connected to the connecting component; the bending component drives the limiting blocks 3 to bend the guardrail 2, reducing the workload of workers installing the guardrail, preventing workers from being accidentally injured when the guardrail 2 bounces back, and ensuring the safety of workers. At the same time, the connecting component is used to adjust the distance between the two posts 1, thereby adapting to guardrails 2 of different lengths and improving the adaptability of the device.

[0020] The fixing assembly includes a stop bar 103 and a first connecting plate 105; at least two stop bars 103 are fixedly connected to the upper left side of the fixing plate 4; such as Figure 2As shown, a first connecting plate 105 is fixedly connected to the lower rear part of the fixed plate 4; the height of the first connecting plate 105 is always consistent with the height of the cement road surface. The first connecting plate 105 restricts the rotation of the fixed plate 4 when it is under force, preventing the fixed plate 4 from tilting or deflecting when the limit block 3 bends the guardrail 2, thus reducing the failure rate of the device.

[0021] The bending assembly includes a second connecting rod 101, a first pulley 104, an electric rotating rod 106, a second connecting plate 107, a first connecting rod 108, and a third connecting plate 109. The electric rotating rod 106 is fixedly connected to the upper right side of the slide plate 5. The second connecting plate 107 is rotatably connected to the upper rear side of the slide plate 5. The end of the second connecting plate 107 away from the slide plate 5 is fixedly connected to an adjacent limiting block 3. The lower left side of the second connecting plate 107 is rotatably connected to the first connecting rod 108. The middle part of the first connecting rod 108 is rotatably connected to the rear side of the slide plate 5. The end of the first connecting rod 108 away from the second connecting plate 107 is rotatably connected to the third connecting plate 109. The upper side of the third connecting plate 109 is fixedly connected to an adjacent limiting block 3. The lower side of the third connecting plate 109 is fixedly connected to the second connecting rod 101. The end of the second connecting rod 101 away from the third connecting plate 109 is movably connected to the slide plate 5. Several first pulleys 104 are rotatably connected to the lower side of the slide plate 5.

[0022] The connecting assembly includes a steel rope 201, a locking buckle 202, and a top rod 203; the steel rope 201 is wound around the outer surface of the electric rotating rod 106; the locking buckle 202 is fixedly connected to the end of the steel rope 201 away from the electric rotating rod 106; as Figure 4 As shown, the steel rope 201 is wound in an S-shape around all the retaining bars 103; the back of the fixing plate 4 is connected to the top rod 203 by a spring; by winding the steel rope 201 in an S-shape around the retaining bars 103, the force direction of the column 1 when bending the guardrail 2 is changed, thereby preventing the column 1 from being squeezed backward by the guardrail 2 and ensuring that the installed column 1 meets industrial requirements.

[0023] It also includes an electric slider 102 and a drive unit 110; the electric slider 102 is slidably connected to the upper right side of the fixed plate 4; the upper side of the electric slider 102 is fixedly connected to the adjacent limiting block 3; the limiting block 3 is fixed to the left end of the guardrail 2 by the electric slider 102 sliding back and forth; the drive unit 110 is fixedly connected to the upper left side of the slide plate 5, and the drive unit 110 is an electric push rod; the output end of the drive unit 110 is rotatably connected to the second connecting rod 101.

[0024] The limiting block 3 is set to be an arc shape that fits into the grooves on the front and rear sides of the guardrail 2. During the bending process of the guardrail 2, the limiting block 3 that fits into the grooves of the guardrail 2 prevents the guardrail 2 from undergoing irregular deformation, avoids deformation damage to the guardrail 2, and ensures the normal use of the guardrail 2.

[0025] like Figure 2As shown, the lower side of the first connecting plate 105 is serrated. The serrated first connecting plate 105 makes it easier for workers to disassemble and fix the plate 4 on the soil, thus improving the ease of use of the device.

[0026] The specific work involved in installing the railing is as follows: Since the posts 1 are usually driven into the soil on both sides of the road, and the cement road surface is generally higher than the soil road surface, this structure is used to manually place the fixing plate 4 between the post 1 and the cement road surface. At this time, the left side of the fixing plate 4 is compressed by the top rod 203, so that the top rod 203 abuts against the post 1, while the lower front part of the fixing plate 4 contacts the cement road surface, thus locking the fixing plate 4 between the post 1 and the cement road surface. Then, the electric slider 102 drives the limiting block 3 to move backward, thereby fixing the left end of the guardrail 2. At this time, the left end of the guardrail 2 is manually fixed with end bolts, as follows. Figure 3As shown, the skateboard 5 is placed manually on the cement road surface, and the lower front part of the skateboard 5 is inserted into the side of the cement road surface. At this time, the drive component 110 drives the second connecting rod 101 to move backward. With a reference from left to right, this drives the third connecting plate 109 to rotate clockwise, which in turn drives the limiting block 3 on the third connecting plate 109 to rotate clockwise. When the limiting block 3 contacts the rear side of the guardrail 2, the drive component 110 stops. It should be noted that the third connecting plate 109 is initially placed with its upper end facing down to facilitate manual assembly of the skateboard 5 onto the cement road surface. As the limiting block 3 on the third connecting plate 109 continuously moves towards the rear side of the guardrail 2, with a reference from top to bottom... The first connecting rod 108 rotates counterclockwise, causing its left end to move towards the rear of the guardrail 2 and its right end to move towards the front of the guardrail 2. When the right end of the first connecting rod 108 moves, it drives the limiting block 3 located on the second connecting plate 107 to move towards the front of the guardrail 2. This causes the limiting blocks 3 of the second connecting plate 107 and the third connecting plate 109 to cooperate in clamping the front and rear of the guardrail 2. At this time, the electric drive slide plate 5 moves along the side of the concrete road via the first pulley 104, thereby causing the limiting blocks 3 to bend the guardrail 2. The limiting blocks 3, which fit into the grooves of the guardrail 2, bend the guardrail 2. To prevent abnormal deformation of guardrail 2 during bending and avoid damage, ensuring its normal use, the limiting block 3 on the third connecting plate 109 is used to reduce the backward compressive force of guardrail 2 during bending. This reduces the pressure of guardrail 2 on the left-side post 1, ensuring that the tilt angle of post 1 after installation of guardrail 2 meets specifications and guarantees the buffering effect of guardrail 2 against impacts. Furthermore, to better prevent post 1 from tilting, before the sliding plate 5 is in operation, the locking buckle 202 is manually locked to the left-side post 1, and the steel rope 201 is wound in an S-shape around the stop bar 103. When the sliding plate 5 is in operation, the electric rotating rod 106 moves the steel rope 201... During continuous placement, the column remains taut. At this time, the steel cable 201 applies a forward pulling force to the column 1, which counteracts the backward squeezing force exerted on the column 1 by the deformation of the guardrail 2. This prevents the column 1 from tilting due to the pressure from the guardrail 2. Simultaneously, the steel cable 201, wound in an S-shape around the stop bar 103, distributes the pulling force of the column 1 to the left and right sides, preventing the fixing plate 4 from being subjected to backward squeezing force by the steel cable 201, ensuring the normal operation of the device. Because the fixing plate 4 is subjected to a leftward pulling force under the taut state of the steel cable 201, viewed from above, the fixing plate 4 has a tendency to tilt and rotate to the left. To prevent the fixing plate 4 from shifting or rotating, as... Figure 2As shown, when the fixing plate 4 is placed manually, the first connecting plate 105 is inserted into the soil. The first connecting plate 105, fixed to the soil and the side of the cement road, restricts the deflection of the fixing plate 4, thus ensuring the normal operation of the device. Simultaneously, the serrated first connecting plate 105 makes it easier for workers to disassemble the fixing plate 4 on the soil, improving the device's usability. Through the above operations, the limiting block 3 on the third connecting plate 109 cooperates with the steel rope 201 to prevent the column 1 from tilting during the installation of the guardrail 2, ensuring the guardrail 2's buffering capacity. When the sliding plate 5 moves the limiting block 3 to the right side of the column 1, the bending of the guardrail 2 is completed. Only the right end of the guardrail 2 needs to be fixed manually with bolts, greatly improving the bending efficiency of the guardrail 2 and preventing accidental injury to workers during bending, ensuring worker safety. Furthermore, due to... Different specifications of guardrail 2 have different lengths. To improve the adaptability of the device, the electric rotating rod 106 is used to rewind and release the steel rope 201 to adapt to guardrail 2 of different lengths. This allows the sliding plate 5 to move in coordination with the steel rope 201 when installing guardrail 2 of different lengths, thus enabling the sliding plate 5 to adapt to the installation of guardrail 2 of different lengths. After the guardrail 2 is installed, the locking buckle 202 is released manually, and the drive component 110 is controlled to retract. The limit block 3 releases its clamp on the guardrail 2. The first connecting plate 105 is pulled out of the soil manually. Then, the fixing plate 4 and the sliding plate 5 are removed from the cement road surface to complete the disassembly of the device. When the worker needs to install the next guardrail 2, the locking buckle 202 is released, the second connecting rod 101 is driven to retract, and the third connecting plate 109 is returned to the initial position. The fixing plate 4 and the first connecting plate 105 are moved to the next post 1, and the above operation is repeated. Example

[0027] Based on Example 1, such as Figures 6-8 As shown, it also includes a cleaning system, which includes a cleaning block 301, an inclined plate 302, a second pulley 303, and a pressing wheel 304. The cleaning block 301 is fixed to the right side of the slide plate 5. The inclined plate 302 is fixed to the right side of the cleaning block 301. At least two second pulleys 303 are rotatably connected to the front side of the cleaning block 301. At least three pressing wheels 304 are rotatably connected to the lower side of the cleaning block 301. Based on a top-down view, the cleaning block 301 removes and cleans the soil during the movement of the first pulley 104 to the right, preventing the device from being jammed by soil and gravel, reducing the failure rate of the device. The cleaning block 301 guides the cleaned soil to the upper and lower sides, preventing soil from accumulating on the upper and lower sides of the inclined plate 302 and hindering the normal operation of the device. The pressing wheel 304 compacts the relatively loose soil during the movement, and the compacted soil enhances the fixing effect on the column 1, preventing the column 1 from tilting under force and ensuring that the installation angle of the column 1 meets the requirements.

[0028] With a view from right to left as a reference, the inclined plate 302 gradually tilts downward from front to back. The downward tilting inclined plate 302 guides the soil on the lower side toward the extrusion wheel 304. In conjunction with the extrusion wheel 304 compacting the soil, the device improves the fixing effect on the column 1.

[0029] The specific work of cleaning up the soil is as follows: Because the skateboard 5 moves along the side of the cement road, the first pulley 104 is easily jammed by mud and gravel, causing the device to malfunction. To avoid this, when the skateboard 5 is running, it drives the cleaning block 301 to move synchronously. The right side of the cleaning block 301 is used to remove and clean the mud on the side of the cement road. At the same time, the inclined plate 302 guides the cleaned mud to the upper and lower sides, preventing the mud from being discharged only from the upper or lower side of the inclined plate 302, which would cause the mud to accumulate and affect the operation of the device. Furthermore, the downward-sloping inclined plate 302 guides the mud on the lower side to the extrusion wheel 304. With the extrusion wheel 304 compacting the mud, the device's fixation effect on the column 1 is improved. The mud on the upper side of the inclined plate 302 is discharged normally, ensuring the normal operation of the device. Example

[0030] Based on Example 2, such as Figure 9 and Figure 10 As shown, it also includes a buffer detection system, which includes a rubber block 401 and a pressure sensor 402; the rubber block 401 is fixedly attached to the rear side of the cleaning block 301; the pressure sensor 402 is fixedly attached inside the rubber block 401; the pressure sensor 402 measures the magnitude of the squeezing force on the rubber block 401 when the column 1 tilts, thereby detecting the tilt state of the column 1.

[0031] The specific steps of buffer detection are as follows: Since the angle between post 1 and the cement road surface is between 70 and 80 degrees after installation, the maximum buffering effect and seismic resistance of guardrail 2 are ensured. When the right end of guardrail 2 is installed on post 1 with bolts, post 1 tilts forward due to the force of the guardrail 2's rebound. To ensure that the tilt angle of guardrail 2 meets the specifications, rubber block 401 is inserted into post 1 and the side of the cement road. Rubber block 401 buffers and protects post 1, preventing post 1 from being directly pulled tilted by guardrail 2. At this time, rubber block 401 deforms under force, which transmits the squeezing force of post 1 to pressure sensor 402. When the tilt angle of post 1 meets the specifications, pressure sensor 402 does not react. When the tilt angle of post 1 is too large, the squeezing force of post 1 on rubber block 401 exceeds the pressure range detected by pressure sensor 402. Therefore, pressure sensor 402 will alarm when it detects excessive pressure. Pressure sensor 402 will also alarm when it detects insufficient pressure, reminding workers to deal with the situation in time and ensure the continued use of guardrail 2. Example

[0032] Based on Examples 1 and 2, such as Figure 1 , Figure 2 and Figure 11 As shown, it also includes locking rods 501; at least two locking rods 501 are fixed to the rear sides of the two limit blocks 3 located above the fixing plate 4; several threaded holes 2001 are opened on the left and right sides of the guardrail 2; during the bending process of the guardrail 2, the left end of the guardrail 2 is fixed to the post 1 by bolts, and the bolts are prone to stripping and loosening due to the pressure during the bending process of the guardrail 2, which greatly reduces the buffering and shock absorption effect of the guardrail 2 in the later stage. In order to prevent this phenomenon, when the electric slider 102 drives the limit When the left end of the guardrail 2 is fixed by the positioning block 3, the locking rod 501 passes through the threaded holes 2001 in the upper left and lower left parts of the guardrail 2, and cooperates with the right end of the guardrail 2 that is fixed on the column 1 to lock onto the column 1. At this time, the guardrail 2 is bent. After the right end of the guardrail 2 is fixed by bolts, the worker fixes the bolts through the threaded holes 2001 in the middle left part of the guardrail 2. This avoids the bolts from slipping and loosening during the bending of the guardrail 2, and ensures the buffering effect of the guardrail 2 in the later stage.
