Description
Technical Field
[0001] The utility model relates to the technical field of high pier construction safety equipment, in particular to a high pier construction safety device for crossing a highway ramp. Background Technique
[0002] When constructing a highway, after the high pier is constructed, it needs to be inspected and processed. The traditional processing method uses a lift to drive the safety protection frame to move, and the staff stands inside the frame to inspect the high pier. In actual operation, the safety protection mechanism of the staff is generally a safety belt sleeved outside the guardrail. Since the guardrails are connected by vertical rods, the moving range of the staff is limited at this time. And when inspecting the parts on both sides of the guardrail, when the detected parts on both sides are few, for the convenience of the staff, they often do not move the lift left and right, and handle it by standing on tiptoe and leaning forward. At this time, the center of gravity of the safety frame shifts, which easily causes damage to the frame and the lifting mechanism. Therefore, a high pier construction safety device for crossing a highway ramp is proposed for the above problems. Content of the Utility Model
[0003] The purpose of the utility model is to provide a high pier construction safety device for crossing a highway ramp to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] As an optional scheme of a high pier construction safety device for crossing a highway ramp described in the utility model, wherein: a high pier construction safety device for crossing a highway ramp includes a protective guardrail and a base assembly,
[0006] The protective guardrail is fixedly connected above the base assembly;
[0007] The base assembly includes a bottom frame, a guide rod and a first lock. The top of the bottom frame is fixedly connected with a protective guardrail. A plurality of groups of horizontally arranged guide rods are embedded on the surface of the bottom frame. A first lock is arranged outside the guide rod. A connecting belt is fixedly connected to the surface of the first lock, and the other end of the connecting belt is fixedly connected with a second lock;
[0008] One side inside the bottom frame is fixedly connected with a motor. The end of the main shaft of the motor is fixedly connected with a threaded rod. The other end of the threaded rod is rotatably connected with the bottom frame. A counterweight block is spirally connected to the outside of the threaded rod;
[0009] A support plate is further arranged below the motor. A plurality of groups of connecting rods are slidably connected inside the support plate. The bottom of the connecting rod is fixedly connected with a connecting frame. A pressure sensor is fixedly connected above the connecting frame. A longitudinally arranged rotating shaft is also fixedly connected inside the connecting frame.
[0010] During the construction of expressways, after the construction of high piers is completed, it is necessary to inspect and process them. In the traditional processing method, a lift is used to drive the safety protection frame to move, and the staff stands inside the frame to inspect the high piers. In actual operation, the safety protection mechanism of the staff is generally to put on a safety belt outside the guardrail. Since the guardrails are connected by vertical rods, the movement range of the staff is limited at this time. And when inspecting the parts on both sides of the guardrail, when the number of detected parts on both sides is small, for the convenience of the staff, they often do not let the lift move left and right, and handle it by standing on tiptoe and leaning forward. At this time, the center of gravity of the safety frame shifts, which is likely to cause damage to the frame and the lifting mechanism. And when this device is in use, it is externally powered. The first buckle is sleeved outside the guide rod, and the second buckle is fixed on the staff. At this time, when the staff moves, it will drive the first buckle to move outside the guide rod. At this time, the movement range of the staff can be guaranteed, which is convenient for inspecting and processing high piers. When working, when the staff stands on one side inside the guardrail, the center of gravity shifts. When the difference in the numerical values of the pressure sensors on both sides exceeds the set threshold, at this time, the external controller controls the motor to drive the counterweight to rotate, and the counterweight drives the support plate to move. At this time, the adjustment of the center of gravity can be realized to ensure that the equipment is not easily damaged.
[0011] As an alternative scheme of a safety device for high pier construction across expressway ramps described in the present utility model, wherein: a spring is arranged outside the connecting rod, one end of the spring is fixedly connected to the connecting rod, and the bottom of the connecting rod is fixedly connected to the support plate.
[0012] As an alternative scheme of a safety device for high pier construction across expressway ramps described in the present utility model, wherein: the connecting rods are arranged in multiple groups, and the connecting rods are arranged in a T shape.
[0013] As an alternative scheme of a safety device for high pier construction across expressway ramps described in the present utility model, wherein: the front and rear sides of the counterweight are in contact with the bottom frame and are slidably arranged.
[0014] As an alternative scheme of a safety device for high pier construction across expressway ramps described in the present utility model, wherein: the number of the support plates is two groups, and the support plates are distributed front and back about the center of the bottom frame.
[0015] The rotating shaft below the connecting frame is connected to the lifting mechanism, and pressure sensors are arranged above the connecting frame. When the staff stands in the center of the bottom frame, the pressure sensors on both sides are evenly stressed. When the staff stands on one side of the bottom frame and leans outwards, at this time, the difference in the numerical values of the pressure sensors on both sides is too large, and the center of gravity is adjusted through the external controller to ensure the long-term use of the equipment.
[0016] Compared with the prior art, the beneficial effects of the present utility model are:
[0017] When the utility model is in use, the first buckle is sleeved outside the guide rod, and the second buckle is fixed on the staff. At this time, when the staff moves, it will drive the first buckle to move outside the guide rod, so as to ensure the moving range of the staff and facilitate the inspection and treatment of high piers.
[0018] During work, when the staff stands on one side inside the guardrail, the center of gravity shifts. When the difference in the values of the pressure sensors on both sides exceeds the set threshold, at this time, the external controller controls the motor to drive the counterweight to rotate, and the counterweight drives the support plate to move, so as to adjust the center of gravity and ensure that the equipment is not easily damaged.
[0019] The rotating shaft below the connecting frame is connected to the lifting mechanism, and pressure sensors are arranged above the connecting frame. When the staff stands in the center of the bottom frame, the pressure sensors on both sides are evenly stressed. When the staff stands on one side of the bottom frame and leans outwards, at this time, the difference in the values of the pressure sensors on both sides is too large, and the center of gravity is adjusted through the external controller to ensure the long-term use of the equipment.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Example 1
[0027] Please refer to Figure 1 、 Figure 2 and Figure 3 , the present utility model provides a technical solution:
[0028] A high pier construction safety device for crossing a high-speed ramp, comprising a protective guardrail 1 and a base assembly 2,
[0029] The above-mentioned protective guardrail 1 is fixedly connected above the base assembly 2;
[0030] The above-mentioned base assembly 2 includes a bottom frame 201, a guide rod 202 and a first lock 203. The top of the bottom frame 201 is fixedly connected with a protective guardrail 1. A plurality of horizontally arranged guide rods 202 are embedded on the surface of the bottom frame 201. A first lock 203 is arranged outside the guide rod 202. A connecting belt 204 is fixedly connected to the surface of the first lock 203. The other end of the connecting belt 204 is fixedly connected with a second lock 205;
[0031] A motor 206 is fixedly connected to one side inside the bottom frame 201. The end of the main shaft of the motor 206 is fixedly connected with a threaded rod 207. The other end of the threaded rod 207 is rotatably connected with the bottom frame 201. A counterweight 208 is spirally connected to the outside of the threaded rod 207;
[0032] A support plate 209 is further arranged below the motor 206. A plurality of connecting rods 210 are slidably connected inside the support plate 209. The bottom of the connecting rod 210 is fixedly connected with a connecting frame 213. A pressure sensor 212 is fixedly connected above the connecting frame 213. A longitudinally arranged rotating shaft 214 is also fixedly connected inside the connecting frame 213.
[0033] During the construction of expressways, after the construction of high piers, they need to be inspected and processed. In the traditional processing method, a lift is used to drive the safety protection frame to move, and the staff stands inside the frame to inspect the high piers. In actual operation, the safety protection mechanism of the staff is generally to put on a safety belt outside the guardrail. Since the guardrails are connected by vertical rods, the moving range of the staff is limited at this time. And when inspecting the parts on both sides of the guardrail, when the number of detected parts on both sides is small, for the convenience of the staff, they often do not let the lift move left and right, and handle it by standing on tiptoe and leaning forward. At this time, the center of gravity of the safety frame shifts, which is likely to cause damage to the frame and the lifting mechanism. When this device is in use, it is externally powered. The first lock 203 is sleeved outside the guide rod 202, and the second lock 205 is fixed on the staff. At this time, when the staff moves, it will drive the first lock 203 to move outside the guide rod 202. At this time, the moving range of the staff can be guaranteed, which is convenient for inspecting and processing high piers. When working, when the staff stands on one side inside the guardrail, the center of gravity shifts. When the values of the pressure sensors 212 on both sides differ by more than the set threshold, at this time, the external controller controls the motor 206 to drive the counterweight 208 to rotate, and the counterweight 208 drives the support plate 209 to move. At this time, the adjustment of the center of gravity can be realized to ensure that the equipment is not easily damaged;
[0034] In this embodiment, the controller is installed on the surface of the lifting equipment. And this device is provided with three groups of guide rods 202, and three people can work safely at a time. And when moving, its first lock 203 can move along with the staff. At this time, it is convenient for the staff to work. And once the vertical difference between the pressure sensors 212 on both sides is large, it means that the staff are concentrated on one side, or the staff make dangerous actions such as leaning forward. The center of gravity of the equipment shifts, and it is easy to have problems such as the equipment tilting and falling. At this time, through the position adjustment of the counterweight 208, the stability of the device can be guaranteed to ensure the safety of the staff during work.
[0035] Embodiment 2
[0036] This embodiment is an improvement on Embodiment 1. Please refer to Figure 4 , specifically, a spring 211 is arranged outside the connecting rod 210, one end of the spring 211 is fixedly connected to the connecting rod 210, and the bottom of the connecting rod 210 is fixedly connected to the support plate 209.
[0037] The connecting rod 210 is arranged in multiple groups, and the connecting rod 210 is arranged in a T shape.
[0038] The front and rear sides and the bottom of the counterweight 208 are in contact with the bottom frame 201 and are slidably arranged.
[0039] The number of the above-mentioned support plates 209 is two groups, and the support plates 209 are distributed front and back with respect to the center of the bottom frame 201.
[0040] The rotating shaft 214 below the connecting frame 213 is connected to the lifting mechanism, and the pressure sensor 212 is arranged above the connecting frame 213. When the staff stands in the center of the bottom frame 201, the pressure sensors 212 on both sides are evenly stressed. When the staff stands on one side of the bottom frame 201 and leans outwards, at this time, the values of the pressure sensors 212 on both sides differ greatly. The external controller is used to adjust the center of gravity to ensure the long-term use of the equipment.
[0041] In this embodiment, there is a certain gap between the connecting rod 210 and the support plate 209. When the staff stands on one side of the bottom frame 201, it can detect the pressure through the pressure sensor 212 on this side, while the force on the pressure sensor 212 on the other side becomes smaller, which helps to detect the center of gravity deviation through the pressure sensors 212 on both sides. A spring 211 is arranged outside the connecting rod 210. In the normal state, it stably presses the bottom frame 201 to press the pressure sensor 212 to ensure the stability of the support plate 209. The connecting rod 210 is arranged in a T shape to prevent the connecting rod 210 from detaching from the support plate 209, and the support plate 209 is located below the counterweight 208, which will not affect the contraction action of the lifting mechanism.
[0042] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
[0043] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
