Description

Technical Field

[0001] This invention relates to the technical field of lateral safety warning devices for beam-moving machines, specifically a lateral safety warning device for beam-moving machines. Background Technology

[0002] A beam mover is a large piece of machinery used to move large concrete beams. It is commonly used in engineering fields such as bridge construction. It usually has a large working range and a high lifting capacity, and can accurately move prefabricated beams to designated locations on the construction site. However, due to the large size and heavy weight of the beams, the beam mover requires extremely precise control during operation. Any slight deviation may lead to serious safety accidents, especially when moving the beams laterally. Because the lateral stability of the beams is relatively poor, they are easily affected by various factors and may sway or deviate, posing a huge safety threat to the surrounding construction personnel and equipment.

[0003] A lateral safety warning device for a beam-moving machine, patent publication number CN221645585U, includes four sets of support frames mounted on the beam-moving machine. These four sets of support frames are positioned at the four corners of the beam-moving machine, and each set of support frames is equipped with a warning component. The warning component includes: a warning pole mounted on the support frame; and a traffic cone suspended from the end of the warning pole near the edge of the beam-moving machine. The four sets of warning poles and traffic cones form a rectangular working area for the beam-moving machine. This application improves the installation efficiency of the warning device by fixing the four sets of support frames to the four corners of the beam-moving machine, fixing the warning poles to the support frames, and suspending the traffic cones from the end of the warning poles near the edge of the beam-moving machine. The four sets of warning poles and traffic cones are located at the four corners of the beam-moving machine. Furthermore, when the beam-moving machine moves, the warning poles and traffic cones also move with the beam-moving machine, thus improving the installation efficiency of the warning device on the beam-moving machine.

[0004] However, the aforementioned lateral safety warning device for the beam-moving machine can only warn and protect the equipment when it is stationary. When the equipment is running at a slow speed, if the surrounding personnel are not careful, when the equipment moves close to them, it is very likely to cause danger due to being too close to the equipment, which may lead to an accident and cause casualties. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a lateral safety warning device for beam-moving machines, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lateral safety warning device for a beam-moving machine, comprising a beam-moving machine base, a caster wheel fixed to the bottom surface of the beam-moving machine base, an electric push rod provided to the bottom surface of the beam-moving machine base, a friction plate fixed to the bottom surface of the electric push rod, a friction block fixed to the bottom surface of the friction plate, an alarm device provided to the bottom surface of the beam-moving machine base for providing warnings when the beam-moving machine base is in motion, an auxiliary device provided on the side of the beam-moving machine base for providing range warnings when the beam-moving machine base is stationary, and a protective device provided on the side wall of the beam-moving machine base for protection when in motion;

[0007] The alarm device includes a sliding block, a short rod, a fixed plate, a rotating rod, an alarm device, a hinge plate, a transmission rod, and a warning plate. The side wall of the friction plate is provided with a sliding groove. The sliding block is slidably connected to the inner wall of the sliding groove. The short rod is fixedly connected to the side of the sliding block away from the friction plate. When the friction plate moves up and down, it drives the sliding block to slide, and the sliding block drives the short rod to move.

[0008] According to the above technical solution, the fixed plate is fixedly connected to the bottom surface of the beam moving machine base, the rotating rod is rotatably connected to the inner wall of the fixed plate, the end of the short rod away from the sliding block passes through one end of the rotating rod and is rotatably connected at the point of penetration, the alarm device is fixedly connected to the front of the fixed plate, and the hinge plate is slidably connected to the front of the fixed plate. When the short rod moves, it drives the rotating rod to rotate, which in turn squeezes the alarm device to sound an alarm.

[0009] According to the above technical solution, a support rod is fixed to the other end of the rotating rod. The outer wall of the support rod is in contact with the bottom surface of the hinge plate. The bottom end of the transmission rod is hinged to the upper surface of the hinge plate. A crossbar is fixed to the front of the beam-moving machine base. The crossbar passes through the warning plate and is rotatably connected at the point of penetration. The upper end of the transmission rod is fixedly connected to the bottom surface of the warning plate. When the rotating rod rotates and no longer supports the hinge plate, the hinge plate slides downward under gravity, causing the warning plate to rotate.

[0010] According to the above technical solution, the auxiliary device includes an extension rod, a first hinge rod, a second hinge rod, a traffic cone, a guardrail, a counterweight, and a rotating block. The extension rod passes through the base of the beam-moving machine and is slidably connected at the penetration point. When the warning plate rotates, it pushes the extension rod to slide.

[0011] According to the above technical solution, the upper end of the first hinge rod is hinged to the side wall of the beam-moving machine base, the upper end of the second hinge rod is hinged to the end of the extension rod away from the beam-moving machine base, and the bottom end of the second hinge rod is hinged to the bottom end of the first hinge rod. When the extension rod slides, it drives the first hinge rod and the second hinge rod to rotate.

[0012] According to the above technical solution, the upper end of the traffic cone is hinged to the hinge joint of the first hinge rod and the second hinge rod. The guardrail is rotatably connected to the side wall of the beam-moving machine base. A rotating block is fixed to the side wall of the guardrail. The counterweight is fixedly connected to the right end of the guardrail. The rotating block is fixedly connected to the side wall of the guardrail. When the first hinge rod and the second hinge rod rotate, they drive the traffic cone to move up and down.

[0013] According to the above technical solution, the protective device includes a protective plate, a connecting rod, a pressing rod, a limiting plate, a limiting block, and a spring. The protective plate passes through the base of the beam-moving machine and is slidably connected at the penetration point. When the guardrail rotates, it pushes the protective plate to slide upward.

[0014] According to the above technical solution, the connecting rod is fixedly connected to the upper surface of the beam-moving machine base, the side wall of the clamping rod is provided with a groove, the bottom surface of the clamping rod is hinged to the end of the connecting rod away from the beam-moving machine base, the limiting plate is rotatably connected to the inner wall of the groove, and the limiting plate moves when the protective plate slides upward.

[0015] According to the above technical solution, the side wall of the beam moving machine base is provided with a sliding groove, the limiting block is slidably connected to the inner wall of the sliding groove, the bottom end of the spring is fixedly connected to the upper surface of the limiting block, and the top end of the spring is fixedly connected to the bottom surface of the limiting plate. When the limiting plate moves, it drives the limiting block to slide and stretches the spring at the same time.

[0016] This invention provides a lateral safety warning device for a beam-moving machine. It has the following beneficial effects:

[0017] 1. This invention includes an alarm device. When the device moves, it works in conjunction with a sliding block, a short rod, and a fixed plate to rotate a rotating rod. Pressing the switch on the alarm device activates a timely alarm during operation, alerting nearby personnel to move away promptly and preventing casualties in the event of an accident. This solves the problem that existing warning devices can only provide warnings in a very small area. Simultaneously with the alarm, a hinged plate and a transmission rod rotate a warning plate, exposing warning signs on it. This provides multi-sensory warnings to those nearby, further enhancing the warning effect and allowing them to quickly recognize danger and evacuate. This addresses the problem that a single alarm device cannot effectively convey information.

[0018] 2. This invention includes an auxiliary device that, in conjunction with the extension rod, the first hinge rod, and the second hinge rod, moves the traffic cones. When the equipment is stationary, the traffic cones are used to demarcate the area, thus avoiding the need for workers to manually move the traffic cones, reducing the time spent measuring the site, improving work efficiency, and solving the problem of workers having to repeatedly measure and demarcate the site before parking the equipment in the required position. Simultaneously, when stationary, the device works with a counterweight to rotate the guardrails, blocking access in front of and behind the equipment, preventing personnel and objects from entering the dangerous area of ​​the beam-moving machine. This solves the problem of personnel or objects easily entering dangerous areas and causing accidents, reducing the accident rate and ensuring the safety of personnel and equipment.

[0019] 3. This invention is equipped with a protective device. When the equipment is transporting the crossbeam, an auxiliary device pushes the protective plate up to block the crossbeam from the front and rear of the equipment, preventing the crossbeam from rolling off during transport and causing injury or death to surrounding personnel or damage to property, thus solving the problem of round crossbeams easily rolling off during transport. At the same time as the protective plate is raised, the connecting rod, limiting plate, limiting block and spring drive the clamping rod to rotate, pressing the crossbeam from above, thereby further improving the stability of the crossbeam on the equipment. This prevents the equipment from encountering rough ground when transporting the crossbeam, which would cause large shaking and shake off the crossbeam loaded on the equipment, thus solving the problem of accidents caused by rough ground during equipment operation.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-9 One embodiment of the present invention is: a lateral safety warning device for a beam-moving machine, including a beam-moving machine base 1, a caster wheel 2 fixed on the bottom surface of the beam-moving machine base 1, an electric push rod 3 provided on the bottom surface of the beam-moving machine base 1, a friction plate 4 fixed on the bottom surface of the electric push rod 3, and a friction block fixed on the bottom surface of the friction plate 4. The electric push rod 3 is remotely controlled to drive the friction plate 4 to descend, and the descent of the friction plate 4 causes the friction block to move downward as well, so that the friction block touches the ground, increasing the friction between the equipment and the ground. An alarm device is provided on the bottom surface of the beam-moving machine base 1 to provide a warning when the beam-moving machine base 1 is in motion.

[0032] The alarm device includes a sliding block 51, a short rod 52, a fixed plate 53, a rotating rod 54, an alarm device 55, a hinge plate 56, a transmission rod 57, and a warning plate 58. A groove is provided on the side wall of the friction plate 4. The sliding block 51 is slidably connected to the inner wall of the groove. When the friction plate 4 moves up and down, it drives the sliding block 51 to move up and down as well. The short rod 52 is fixedly connected to the side of the sliding block 51 away from the friction plate 4. While the sliding block 51 moves up and down, it also drives the short rod 52 to move back and forth. The fixed plate 53 is fixedly connected to the bottom surface of the beam-moving machine base 1. The rotating rod 54 is rotatably connected to the inner wall of the fixed plate 53. The back-and-forth movement of the short rod 52 drives the rotating rod 54 to rotate. One end of the short rod 52, away from the sliding block 51, passes through one end of the rotating rod 54, and the point of penetration is rotatably connected. The alarm device 55 is fixedly connected to the front of the fixed plate 53. When the rotating rod 54 rotates to the alarm device 55, it pushes the button above the alarm device 55, causing the alarm device 55 to sound an alarm and alert surrounding personnel that the vehicle is in motion. The hinge plate 56 is slidably connected to the front of the fixed plate 53. The other end of the rotating rod 54 is fixed with a support rod, the outer wall of which is in contact with the bottom surface of the hinge plate 56. When the long end of the rotating rod 54 rotates downward, the hinge plate 56 is no longer supported by the rotating rod 54 and moves downward under its own weight. The transmission rod 57... The bottom end is hinged to the upper surface of the hinge plate 56. When the hinge plate 56 moves downward, it drives the end of the transmission rod 57 that is hinged to the hinge plate 56 to move downward. A crossbar is fixed on the front of the beam-moving machine base 1. The crossbar passes through the warning plate 58 and is rotatably connected at the point of penetration. The upper end of the transmission rod 57 is fixedly connected to the bottom surface of the warning plate 58. When the hinge point of the transmission rod 57 and the hinge plate 56 moves downward, it drives the transmission rod 57 to rotate. When the transmission rod 57 rotates, it pulls the warning plate 58 to rotate around the crossbar, exposing the warning sign. The alarm device moves in conjunction with the sliding block 51, the short rod 52 and the fixed plate 53 to drive the rotating rod 54 to rotate. Pressing the alarm device 55... The switch on the surface allows the device to issue an alarm in a timely manner while in operation, thereby reminding people in the surrounding area to stay away in time and avoid casualties in the event of an accident. This solves the problem that existing warning devices can only provide warnings in a very small area. While the alarm device 55 issues an alarm, it works in conjunction with the hinge plate 56 and the transmission rod 57 to rotate the warning plate 58, causing the warning signs on the warning plate 58 to be exposed. This provides a multi-sensory warning to people in the surrounding area, further enhancing the warning effect and allowing people in the surrounding area to realize the danger more quickly and evacuate. This solves the problem that a single alarm device 55 cannot effectively convey information.

[0033] In this embodiment, during operation: When the device moves, the electric push rod 3, controlled remotely, drives the friction plate 4 to rise. The rising friction plate 4 also moves the friction block upwards. As the friction plate 4 moves upwards, it also drives the sliding block 51 upwards. As the sliding block 51 moves upwards, it drives the short rod 52 upwards. When the short rod 52 moves upwards, it drives the long end of the rotating rod 54 downwards. When the rotating rod 54 rotates to the alarm device 55, it pushes the button above the alarm device 55, causing the alarm device 55 to sound an alarm, alerting surrounding personnel that the vehicle is moving. When the long end of the rotating rod 54 rotates downwards, the hinge plate 56 is no longer supported by the rotating rod 54 and moves downwards under its own weight. As the hinge plate 56 moves downwards, it drives the end of the transmission rod 57 that is hinged to the hinge plate 56 downwards. The end of the transmission rod 57 away from the hinge plate 56 remains unchanged in the vertical direction. Therefore, when the transmission rod... When the hinge joint between rod 57 and hinge plate 56 moves downward, transmission rod 57 also rotates. When transmission rod 57 rotates, it pulls warning plate 58 to rotate around the crossbar, exposing the warning sign. When the equipment is stationary, the friction plate 4 is driven to descend by controlling electric push rod 3. The descent of friction plate 4 causes friction block to move downward as well, so that friction block touches the ground, increasing the friction between the equipment and the ground. When friction plate 4 moves downward, it drives sliding block 51 to move downward as well. The short rod 52 fixed to the side wall of sliding block 51 passes through the short end of rotating rod 54, and rotating rod 54 is rotatably connected to the inner wall of fixed plate 53. Therefore, when sliding block 51 moves downward, the long end of rotating rod 54 moves upward. When the long end of rotating rod 54 moves upward, it pushes hinge plate 56 to move upward as well. Hinge plate 56 drives transmission rod 57 to rotate, and transmission rod 57 drives warning plate 58 to rotate, retracting the warning sign.

[0034] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, an auxiliary device is provided on the side of the beam-moving machine base 1 to provide a range warning when the beam-moving machine base 1 is stationary. The auxiliary device includes an extension rod 61, a first hinge rod 62, a second hinge rod 63, a traffic cone 64, a guardrail 65, a counterweight 66, and a rotating block 67. The extension rod 61 passes through the beam-moving machine base 1 and is slidably connected at the penetration point. When the warning plate 58 rotates, it pushes the extension rod 61 to extend away from the beam-moving machine base 1 along the inclined surface of the extension rod 61. The upper end of the first hinge rod 62 is hinged to the side wall of the beam-moving machine base 1, and the upper end of the second hinge rod 63 is hinged to the extension rod 61 away from the beam-moving machine base 1. One end of seat 1, the bottom end of hinge rod 63 and the bottom end of hinge rod 62 are hinged together. The upper end of traffic cone 64 is hinged to the hinge point of hinge rod 62 and hinge rod 63. When extension rod 61 is no longer pushed by warning plate 58, hinge rod 62 and hinge rod 63 are no longer pushed by extension rod 61. At the same time, the traffic cone 64 moves downward to the ground due to its own weight, marking a warning area around the equipment. When extension rod 61 extends, it drives hinge rod 62 and hinge rod 63 to rotate, lifting traffic cone 64 to prevent it from being dragged on the ground and damaged when the equipment is moved. Guardrail 65 is rotatably connected to the base of beam moving machine. A rotating block 67 is fixed to the side wall of guardrail 65. When extension rod 61 retracts, it moves to rotating block 67, pushing rotating block 67 to rotate around the central axis through which guardrail 65 and beam-moving machine base 1 pass. Rotating block 67 drives guardrail 65 to rotate, then rotates from vertical to horizontal, intercepting the equipment from the front and rear. Counterweight block 66 is fixedly connected to the right end of guardrail 65, and rotating block 67 is fixedly connected to the side wall of guardrail 65. When extension rod 61 does not push rotating block 67, guardrail 65 rotates from horizontal to vertical under the gravity of counterweight block 66, preparing for subsequent beam handling. This auxiliary device works in conjunction with extension rod 61, first hinge rod 62, and second... The hinge rod 63 moves the traffic cone 64, which divides the area when the equipment is stationary, thus avoiding the need for workers to manually move the traffic cones 64, reducing the time workers spend measuring the site, improving work efficiency, and solving the problem of workers having to repeatedly measure and divide the area before parking the equipment in the required position. While stationary, the hinge rod 63, in conjunction with the counterweight 66, rotates the guardrail 65, blocking access in front of and behind the equipment, thus preventing personnel and objects from entering the dangerous area of ​​the beam-moving machine. This solves the problem of personnel or objects easily entering dangerous areas and causing accidents, reducing the accident rate and ensuring the safety of personnel and equipment.

[0035] The side wall of the beam-moving machine base 1 is equipped with a protective device for protection during operation. The protective device includes a protective plate 71, a connecting rod 72, a clamping rod 73, a limiting plate 74, a limiting block 75, and a spring 76. The protective plate 71 penetrates the beam-moving machine base 1 and is slidably connected at the penetration point. When the equipment is in motion, the guardrail 65 rotates from horizontal to vertical. When the guardrail 65 rotates to the position of the protective plate 71, it pushes the protective plate 71 upward to slide upward, thus raising the protective plate 71 and intercepting the crossbeams at the front and rear of the equipment. The connecting rod 72 is fixedly connected to the upper surface of the beam-moving machine base 1. The side wall of the clamping rod 73 has a groove, and the bottom surface of the clamping rod 73 is hinged to the end of the connecting rod 72 away from the base 1 of the beam mover. When the protective plate 71 is raised, it pushes the clamping rod 73 to rotate around the hinge point between the connecting rod 72 and the clamping rod 73, further pressing the placed crossbeam. The limiting plate 74 is rotatably connected to the inner wall of the groove. When the hinge point of the clamping rod 73 rotates, it drives the limiting plate 74 to move upward. The side wall of the beam mover base 1 has a sliding groove, and the limiting block 75 is slidably connected to the inner wall of the sliding groove. The bottom end of the spring 76 is fixedly connected to the upper part of the limiting block 75. On the surface, the top of spring 76 is fixedly connected to the bottom surface of limiting plate 74. When limiting plate 74 moves upward, it stretches spring 76. When the equipment is stationary, guardrail 65 rotates from vertical to horizontal, and guard plate 71 slides downward to reset under gravity. Limit plate 74 moves downward under the elastic force of spring 76. When limiting plate 74 moves downward, it drives clamping rod 73 to rotate and reset. When the equipment moves the crossbeam, this protective device, in conjunction with auxiliary devices, pushes guard plate 71 to rise, blocking the crossbeam in front of and behind the equipment to prevent the crossbeam from rolling down during transport and causing injury to surrounding personnel. This design prevents injuries or damage to items, thus avoiding safety accidents caused by circular crossbeams rolling and falling during transport. Simultaneously with the raising of the protective plate 71, the connecting rod 72, limiting plate 74, limiting block 75, and spring 76 drive the clamping rod 73 to rotate, clamping the crossbeam from above. This further enhances the stability of the crossbeam on the equipment, preventing significant shaking and the crossbeam from falling off the equipment when encountering uneven ground during transport. This solves the problem of accidents caused by uneven ground affecting the equipment during operation.

[0036] In this embodiment, during operation: When the equipment is in motion, the warning plate 58 rotates, pushing the extension rod 61 along its inclined surface to extend it away from the beam-moving machine base 1. As the extension rod 61 slides outward, it causes the hinge point between the extension rod 61 and the second hinge rod 63 to move. Since the second hinge rod 63 is hinged to the first hinge rod 62, and the hinge point between the first hinge rod 62 and the beam-moving machine base 1 remains unchanged relative to the beam-moving machine base 1, when the hinge point between the second hinge rod 63 and the extension rod 61 moves, both the first hinge rod 62 and the second hinge rod 63 rotate, increasing the angle between the two sets of hinge rods. This lifts the traffic cone 64, and as the extension rod 61 extends outward, it moves away from the guardrail 65. At this point, the guardrail 65 is no longer pushed by the extension rod 61, but rotates under the weight of the counterweight 66, causing the guardrail 65 to change from horizontal to vertical. When the equipment is stationary, the warning plate 58 rotates, the extension rod 61 is no longer pushed by the warning plate 58, and the traffic cone 64 falls to the ground due to its own weight. At the same time, the hinge of the first hinge rod 62 and the second hinge rod 63 rotates under the weight of the traffic cone 64, pushing the extension rod 61 to reset. When the extension rod 61 slides to the rotating block 67 of the guardrail 65, the guardrail 65 rotates under the push of the extension rod 61, changing from vertical to horizontal, and blocking the equipment in front of it.

[0037] When the equipment is in motion, the guardrail 65 rotates from horizontal to vertical. When the guardrail 65 rotates to the guard plate 71, it pushes the guard plate 71 to slide upward, causing the guard plate 71 to rise and intercept the crossbeams in front of and behind the equipment. When the guard plate 71 rises, it pushes the clamping rod 73 to rotate around the hinge between the connecting rod 72 and the clamping rod 73. The groove on the side wall of the clamping rod 73 does not coincide with the center of the hinge between the clamping rod 73 and the connecting rod 72. Therefore, when the clamping rod 73 rotates, the groove on the side wall of the clamping rod 73 also rotates around the hinge between the clamping rod 73 and the connecting rod 72, causing the limiting plate 74 to move upward. When the limiting plate 74 moves upward, it stretches the spring 76. Since the limiting plate 74 is not connected to the hinge between the clamping rod 73 and the connecting rod 72, it will also cause the limiting plate 74 to rotate around the hinge between the clamping rod 73 and the connecting rod 72. The connection point rotates, and the bottom surface of the limiting plate 74 is fixedly connected to the upper surface of the limiting block 75 via the spring 76. Therefore, when the limiting plate 74 rotates around the hinge of the pressing rod 73 and the connecting rod 72, it remains in a horizontal state due to the elastic force of the spring 76. However, the limiting plate 74 will also displace horizontally when rotating around the hinge of the pressing rod 73 and the connecting rod 72, and the limiting block 75 can only slide left and right. Therefore, when the pressing rod 73 rotates, it will drive the limiting plate 74 to move left and right. The limiting plate 74 will drive the spring 76 and the limiting block 75 to move together. When the equipment is stationary, the guardrail 65 rotates from vertical to horizontal, the guard plate 71 slides down and resets under gravity, and the limiting plate 74 moves down under the elastic force of the spring 76. When the limiting plate 74 moves down, it drives the pressing rod 73 to rotate and reset.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
