Description

Technical Field

[0001] The present invention relates to the technical field of road construction equipment, and more particularly, to a top displacement device and method for a movable guardrail on an expressway. Background Art

[0002] The movable guardrail in the median strip of an expressway is generally a combined strengthened movable guardrail (hereinafter referred to as the movable guardrail). When a sudden emergency occurs and one side of the expressway is interrupted and a lane change is required, the movable guardrail needs to be removed.

[0003] However, there are some problems in the process of removing the movable guardrail. One is that the movable guardrail itself is deformed or displaced, resulting in the column in the energy-absorbing bracket being stuck in the sleeve and unable to be pulled out. The other is that due to long-term exposure to wind, rain, and sunlight, the hexagonal head bolts are rusted and worn, making it difficult to twist with conventional wrench tools, resulting in the wheeled bracket supporting the movable guardrail being unable to touch the ground, and the movable guardrail cannot be pushed by four universal wheels.

[0004] If the removal time is too long, it will increase the safety risk of the operators exposed in the construction area, and it is not conducive to rapid lane change, increasing the congestion time of the expressway. At present, many median openings on expressways use combined strengthened movable guardrails, and inevitably face the problems existing in the disassembly with conventional tools.

[0043] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0044] As Figure 1-6 shown, a top displacement device for a movable guardrail on an expressway includes: an underframe 1, a movable part 2 installed on the underframe 1, a lifting frame 3 fixed on the underframe 1, two control handles 4 symmetrically fixed on the lifting frame 3, a lifting mechanism 5 installed on the underframe 1 and the lifting frame 3, two L-shaped support rods 6 arranged on the lifting mechanism 5, a limiting part 7 arranged on the two L-shaped support rods 6, a lifting piece 8 installed on the lifting mechanism 5, and a fixing part 9 arranged on the lifting piece, wherein

[0045] The movable part 2 is adapted to cooperate with the two control handles to assist the underframe 1 in position adjustment;

[0046] The lifting mechanism 5 is adapted to control the two L-shaped support rods 6 to move vertically;

[0047] The limiting part 7 is adapted to limit the position of the top of the lifted movable guardrail;

[0048] The lifting piece 8 is adapted to lift the middle column of the movable guardrail;

[0049] The fixing part 9 is adapted to complete the connection between the lifting piece 8 and the column.

[0050] Optionally, the lifting member 8 includes a mounting rod 10 fixed to the two L-shaped support rods 6, a self-locking winch 11 fixed to the bottom of the mounting rod 10, a rotating handle 12 installed on the self-locking winch 11, a steel wire rope 13 wound and rolled up on the self-locking winch 11, a positioning rod 14 fixed between the two L-shaped support rods 6, a support rod 15 rotatably connected to the positioning rod 14, two auxiliary pulleys 16 rotatably installed at both ends of the support rod 15 and corresponding to the steel wire rope 13, and a supporting member 17 arranged at the bottom of the support rod 15 and the two L-shaped support rods 6. When in use, it can be pre-installed by a lifting machine. The structure 5 controls the two L-shaped support rods 6 to rise and exceed the height of the movable guardrail. Then, the working part 2 controls the base frame 1 to move to the bottom of the movable guardrail. At this time, the end of the wire rope 13 connected to the fixing part 9 can be passed through the two auxiliary pulleys 16 and placed in the pillar to be taken out of the movable guardrail, and connected to the pillar through the fixing part 9. At this time, the staff turns the handle 12 to control the self-locking winch 11 to reel in the wire rope 13, and then pull the pillar out of the movable guardrail, which can effectively solve the problem of difficulty in pulling out the sleeve column and greatly improve the efficiency of pulling out the pillar to ensure the efficiency of dismantling and diversion of the movable guardrail. , the staff can control the height adjustment of the two L-shaped support rods 6 to exceed the height of the movable guardrail in advance through the lifting mechanism 5, and then the staff can control the base frame 1 to move to the bottom of the movable guardrail with the cooperation of the moving part 2, and place the lifting part 8 on the pillar to be removed on the movable guardrail. At this time, through the cooperation of the lifting part 8 and the fixing part 9, the pillar can be lifted out of the movable guardrail, thereby, taking out multiple pillars in the movable guardrail in turn, and the connection between the movable guardrail and the ground can be contacted; then, the base frame 1 is taken out from the movable guardrail, and the two L-shaped support rods 6 can be moved down to the extreme position under the control of the lifting mechanism 5, so as to facilitate the base frame 1 and The two L-shaped support rods 6 can be extended into the bottom of the movable guardrail. At this time, the staff can control the lifting mechanism 5 to drive the two L-shaped support rods 6 to rise to lift the movable guardrail. When multiple devices are working at the same time, the movable guardrail can be smoothly lifted up without adjusting the wheel bracket on the movable guardrail, which is convenient for the movable guardrail to leave the ground and cooperate with the moving part 2 to quickly move and adjust the movable part; and when the movable guardrail is lifted and contacts the limiting part 7, the set limiting part 7 can effectively limit the movement of the movable guardrail, thereby ensuring the stability of the movable guardrail after being lifted up, and it is not easy to tilt or fall, which effectively improves the stability and safety of the movable guardrail when moving;The device is inexpensive and saves operating costs. Compared with the transformation of the movable guardrail in use, the production cost of this device is relatively low, effectively saving operating costs. At the same time, the device has strong functionality and can solve the disassembly difficulties. It can effectively solve the two major difficulties that the sleeve column is difficult to pull out and the universal wheel 40 cannot touch the ground, resulting in the immobility of the movable guardrail. It greatly simplifies the disassembly process of the movable guardrail, saves disassembly time, and improves the efficiency of lane change. During the disassembly operation of the movable guardrail, it only takes 25 minutes for 2 workers to use the new jacking and moving device to complete the disassembly of 1 movable guardrail, saving about 30 minutes compared with the conventional disassembly method and saving more than 2 workers.

[0051] Optionally, the supporting member 17 includes a supporting rod 18 hinged to the bottom of the support rod 15, a control rod 19 rotatably connected to the other end of the supporting rod 18, two limit blocks 20 and two positioning blocks 21 respectively fixed to the bottoms of the two L-shaped support rods 6, two guide rods 22 respectively fixed between the two limit blocks 20 and the two positioning blocks 21, two control sleeves 23 respectively movably sleeved on the two guide rods 22 and fixedly connected to both ends of the control rod 19, two positioning screws 24 respectively threadedly connected to the two control sleeves 23, and two positioning grooves 25 respectively opened on the two guide rods 22. In use, the support rod 15 can be rotated to make the support rod 15 inclined, thereby raising the auxiliary pulley 16 at one end of the support rod 15. At this time, driven by the support rod 15, the supporting rod 18 drives the control rod 19 to move, so that the two control sleeves 23 respectively move along the two guide rods 22. When the two control sleeves 23 reach the limit positions of movement and respectively abut against the two positioning blocks 21, rotate the two positioning screws 24 to control the two positioning screws 24 to be respectively inserted into the two positioning grooves 25, thereby restricting the movement of the two control sleeves 23 on the two guide rods 22 to ensure the stability of the support of the supporting rod 18 on the support rod 15, facilitating the lifting assistance of the inclined support rod 15 and ensuring the smooth removal of the upper column of the movable guardrail with a relatively high height.

[0052] Optionally, the fixing member 9 includes a pull ring 26 connected to the steel wire rope 13, a fixing column 27 fixed to the pull ring 26, a protrusion 28 fixed to one end of the fixing column 27, a movable groove 29 provided on the fixing column 27, a fixing rod 30 movably installed in the movable groove 29, one end of which is fixedly connected to the fixing rod 30, and the other end passes through the movable groove 29 and extends to the outside of the fixing column 27. A toggle block 31, one end of which is fixedly connected to the inner wall of the movable groove 29 and the other end of which is fixedly connected to the fixing rod 30. When it is necessary to pull out the column in the movable guardrail energy absorption bracket, the staff can hold the fixing column 27 and control the fixing rod 30 to move in the movable groove 29 by pressing the toggle block 31, compressing and resetting. The spring 32 allows the fixing rod 30 to completely slide into the movable groove 29. At this time, the staff extends the fixing column 27 into the column and allows the protrusion 28 to be stuck in a fixing groove on the inner wall of the column. At this time, the control of the toggle block 31 is released, and the fixing rod 30 is reset under the elastic force of the reset spring 32, so that one end of the fixing rod 30 can be stuck in another fixing groove on the inner wall of the column, so as to conveniently and quickly complete the connection between the fixing column 27 and the column and ensure the stability of the connection with the column, so that when the self-locking winch 11 reels the wire rope 13, the column can be driven to move up; and after the column is lifted off the energy absorbing bracket, the staff only needs to press the toggle block 31 to drive the fixing rod 30 out of the fixing groove, and then the fixing column 27 can be taken out of the column to pick up and place the next column.

[0053] Optionally, the lifting mechanism 5 includes a manual oil pump 33 installed on the base frame 1, a pedal handle 34 installed on the manual oil pump 33, a gear plate 35 rotatably installed on the telescopic end of the manual oil pump 33, an assembly frame 36 movably connected to the lifting frame 3 through a plurality of rollers, a lifting chain 37 fixedly connected to the assembly frame 36 at one end and meshing with the gear plate 35 at the other end and fixedly connected to the manual oil pump 33;

[0054] The two L-shaped support rods 6 are symmetrically fixed on the assembly frame 36. When the staff moves the base frame 1 and parts of the two L-shaped support rods 6 under the movable guardrail through the moving member 2 and steps on the foot-operated handle 34 to control the telescopic end of the manual oil pump 33 to drive the gear disk 35 to move upward, the lifting chain 37 is meshed and driven. Then, the end of the lifting chain 37 connected to the assembly frame 36 moves upward, driving the assembly frame 36 to move upward to control the two L-shaped support rods 6 to abut against and drive the movable guardrail to move upward away from the ground. At this time, several workers push the lifting frame 3, and with the cooperation of the moving member 2, the movable guardrail can be conveniently moved randomly and placed at different positions on the highway, thereby effectively improving the moving and diversion efficiency of the movable guardrail, shortening the emergency diversion time, reducing the safety risk of the diversion operation, and providing a strong time guarantee for restoring the normal traffic on the highway.

[0055] Optionally, the limiting member 7 includes an H-shaped limiting frame 38 fixed on the lifting frame 3 and corresponding to the two L-shaped support rods 6, and several limiting cone blocks 39 equally spaced and fixed on the lower surface of the H-shaped limiting frame 38. When the lifting mechanism 5 controls the two L-shaped support rods 6 to move upward and lift the movable guardrail, as the movable guardrail moves upward, the corrugated steel guardrail plate on the movable guardrail abuts against the H-shaped limiting frame 38 to complete the clamping of the movable guardrail, and the upper end of the corrugated steel guardrail plate is stuck between several limiting cone blocks 39, thereby effectively preventing the movable guardrail from tipping over when being controlled to move, ensuring the stability of the movable guardrail during movement, and ensuring the safety of the movable guardrail during position adjustment.

[0056] Optionally, the moving member 2 includes two universal wheels 40 and two walking wheels 41 symmetrically installed on the base frame 1. The two universal wheels 40 are arranged at one end of the base frame 1 close to the lifting frame 3. By providing the two universal wheels 40 and the two walking wheels 41, the base frame 1 can be supported, thereby facilitating the movement of the base frame 1 on the ground. During the operation of the universal wheels 40, it is convenient for the staff to control the base frame 1 to turn when moving, and thus it is convenient for the movable guardrail lifted off the ground to move and divert quickly.

[0057] Optionally, friction pads 42 are fixedly connected to the upper surfaces of the two L-shaped support rods 6. The two friction pads 42 are made of rubber material. When the two L-shaped support rods 6 are controlled to rise by the lifting mechanism 5 and the two L-shaped support rods 6 come into contact with the bottom of the movable guardrail, through the two friction pads 42 provided, and since the friction pads 42 are made of rubber material, the friction between the movable guardrail and the two L-shaped support rods 6 can be effectively increased, thereby improving the stability of the two L-shaped support rods 6 when lifting the movable ring, and avoiding the direct contact between the movable guardrail and the two L-shaped support rods 6, causing wear of the two L-shaped support rods 6.

[0058] Optionally, two scale grooves 43 corresponding to the assembly frame 36 are symmetrically formed on the lifting frame 3. When the staff steps on the foot pedal handle 34 to control the operation of the lifting mechanism 5, the staff can observe the two scale grooves 43 to understand the rising position of the assembly frame 36. Furthermore, when multiple devices are used simultaneously, the rising heights of the L-shaped support rods 6 on each device can be ensured to be consistent, thereby ensuring the stability of the lifted movable guardrail.
