Abstract
Description
Technical Field
[0001] This application relates to the field of hoisting technology, and more specifically, to a hoisting and installation mechanism and method for road sign poles. Background Technology
[0002] Traffic sign poles are a crucial part of traffic facilities and form part of the traffic signal system. They are used to manage traffic and indicate driving routes to ensure smooth and safe roads. Because traffic sign poles are long and straight, a crane is needed to lift them to the installation position and erect them in the installation location during the installation process.
[0003] The prior art publication CN114906735A provides a road sign pole hoisting and installation mechanism for highway construction. This mechanism uses a first clamping structure to clamp and fix the bottom of the sign pole, and a second clamping structure to clamp the other end of the sign pole. An extension structure and a lifting structure then vertically suspend the sign pole above the mounting hole, allowing it to assemble with the reserved section of the road. However, during use, the bottom of the sign pole needs to be moved between the first clamping structures for clamping. After clamping one end, the sign pole is placed at an angle to the ground, which may cause wear on the other end, especially when using a sign pole structure that is wider at the bottom and narrower at the top. This could even cause bending near the top, resulting in irreparable damage. Furthermore, during the hoisting of the angled sign pole to a vertical position, after the extension structure extends to determine the clamping position at the top of the sign pole and lifts it, the movement trajectory of the clamping position at the top of the sign pole is greater than a quarter-circle arc, making the coordination and control between the extension structure and the lifting structure during the lifting process quite complex. Summary of the Invention
[0004] This application provides a road sign pole hoisting and installation mechanism and method, which solves the technical problem in the prior art that placing the sign pole at an angle to the ground will cause wear or even bending at the other end of the sign pole, and achieves the technical effect of supporting the sign pole to keep it in a horizontal state.
[0005] This application provides a road sign pole hoisting and installation mechanism, including a base, a clamping mechanism on the base, a supporting mechanism on one side of the base, and an adjusting part slidably connected to one side of the base. The supporting part is slidably provided in the adjusting part, and a lifting part is provided on the adjusting part and the supporting part.
[0006] The supporting part includes a sleeve that is slidably connected to the adjusting part, and one end of the sleeve is slidably provided with a supporting plate for supporting the sign pole;

A first wedge block is fixedly connected to one side of the sliding plate, and the first wedge block slides and presses against a second wedge block fixed in the adjusting part.
[0008] The sleeve in the support section is driven to slide through the adjustment section, and the first wedge block and the second wedge block slide against each other to drive the first wedge block to slide along the height direction of the sleeve, thereby completing the lifting and lowering movement of the support plate to support one end of the sign post.
[0009] By adopting the above technical solution and setting up a support mechanism, after the clamping mechanism clamps one end of the sign pole, it can support the outside of the sign pole, so that the sign pole remains horizontal, thereby preventing the sign pole from tilting or rotating.

The motor drives the lead screw to rotate, causing the two first threaded sleeves to move towards each other, thereby driving the two supporting parts to move closer to each other, and no additional locking structure is required.
[0012] Optionally, a top cover is fixedly connected to the top of the sleeve, and a sliding rod is slidably provided inside the sleeve. One end of the sliding rod extends through the top cover to the outside and is fixedly connected to a support plate for supporting the sign post.
[0013] The slide plate is fixedly sleeved on the outside of the slide rod. The slide plate is slidably connected to the sleeve.

Two fixed rods are symmetrically fixedly connected to one side of the groove. A second wedge block is fixedly connected to the top of the fixed rod. The first wedge block and the second wedge block slide and abut against each other.
[0014] By adopting the above technical solution, when the sleeves in the two supporting parts move closer to each other, the sleeves drive the first wedge block and the second wedge block on them to slide and press against each other, pushing the first wedge block to slide upward along the sleeve, thereby driving the slide plate, slide rod and supporting plate to rise and move until the supporting plate contacts the bottom of the sign pole to achieve support, maintain the horizontal state of the sign pole and prevent the sign pole from tilting or rotating.

[0018] By adopting the above technical solution, the signpost can be hoisted and lifted through the combination of the extension structure and the lifting structure. The through groove facilitates installation when the signpost is hoisted to a vertical position.
[0019] Optionally, adjusting rods are slidably connected to both sides of the base, and both adjusting rods are fixedly connected to the mounting plate in the adjusting part;
[0020] The adjusting rod is slidably connected inside the base, and a third spring is fixed between the adjusting rod and the base. Magnets and electromagnets with magnetic repulsion are respectively embedded inside the adjusting rod and the base. By adjusting the magnetic induction intensity of the electromagnet, the sliding distance of the adjusting rod is changed, so that the support plate moves to one end of the marker rod.
[0021] By adopting the above technical solution and setting an adjustment rod, the position of the supporting mechanism can be easily adjusted, thereby supporting different positions on the outer bottom of the sign post. Through the combination of magnets and electromagnets, the adjustment rod can automatically adjust the moving distance.
[0022] Based on the above technical solution, an infrared emitting module and an infrared receiving module are respectively provided at corresponding positions on one end of the extension structure and the adjustment part. The electromagnet responds to the received signal of the infrared receiving module and controls the increment of the magnetic induction intensity of the electromagnet so that the continued outward movement distance of the adjustment rod does not exceed the current movement distance.
[0023] By adopting the above technical solution, through the cooperation of the infrared transmitting module and the infrared receiving module, the adjustment rod is identified and the adjustment part is slid to the middle of the sign post. The change in the magnitude of the current supplied to the electromagnet is controlled to change the magnetic induction intensity of the electromagnet, so that the continued outward movement distance of the adjustment rod does not exceed the current movement distance, ensuring that the sliding distance of the adjustment part will not exceed the length of the sign post under any circumstances.

[0025] By adopting the above technical solution, the fourth wedge block can be squeezed when the third wedge block moves, thereby causing the fourth wedge block and the mounting rod to move downwards.
[0026] Optionally, a collar is fixedly connected to the bottom end of the mounting rod, and multiple support legs are fixedly connected to the outside of the collar, with a base plate fixedly connected to one end of each support leg.
[0027] By adopting the above technical solution, the support leg and the base plate can be lowered and moved by the lowering and moving of the mounting rod until the base plate contacts the ground, thereby increasing the overall stability and support performance of the support mechanism.
[0028] An installation method for a road sign pole hoisting and installation mechanism includes the following steps:
[0029] a. Fix the middle part of the sign pole with a clamping hoop, and use the lifting and extension structure to horizontally hoist the sign pole between the two clamping plates;
[0030] b. Rotate the threaded rod to move the two clamping plates closer to each other until they fit together, and then fit and fix the end of the sign pole that will be connected to the ground to achieve clamping of one end of the sign pole.
[0031] c. Control the sliding of the adjusting rod to adjust the position of the mounting plate in the adjusting part, so that the supporting plate in the supporting part slides to the outside of the clamping hoop to support the other end of the sign post;
[0032] d. Start the adjustment unit, drive the two sleeves in the support unit to slide closer to each other, and under the sliding and pressing cooperation of the first wedge block and the second wedge block, push the first wedge block and the slide plate to slide along the height direction of the sleeve, thereby pushing the support plate to rise up to support the other end of the sign pole;
[0033] e. The adjusting unit simultaneously drives the third wedge block to squeeze the fourth wedge block, moving the mounting rod downwards until the base plate contacts the ground;

[0035] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0036] 1. By setting up a support mechanism, the clamping mechanism can clamp one end of the sign pole, and the support mechanism can support the bottom of the sign pole, so that the sign pole remains horizontal and will not rotate or tip over, thereby preventing safety accidents.
[0037] 2. By setting an adjustment rod, the position of the supporting mechanism can be easily adjusted, so that the supporting mechanism can support sign poles of different lengths, ensuring that the sign poles remain horizontal, and making it easier for workers to adjust the clamp to the other end of the sign pole for fixation.
[0038] 3. By setting a third wedge block and a fourth wedge block, the third wedge block is used to squeeze the fourth wedge block, thereby lowering and moving the support leg and the base plate until the base plate contacts the ground, which facilitates the increase of the overall stability and support performance of the support mechanism.

Detailed Implementation
[0050] The present application will be further described in detail below with reference to the accompanying drawings.
[0051] Reference Figure 1 , Figure 2 and Figure 5 This application discloses a road sign pole hoisting and installation mechanism, including a base 1, a clamping mechanism 2 for clamping and fixing the sign pole, and a supporting mechanism 3 for supporting the sign pole. A column 22 is fixedly connected to the other side of the top of the base 1. An extension structure 24 for adjusting the position of the sign pole is rotatably connected to the top of the column 22. A lifting structure 23 is installed between the extension structure 24 and the column 22. A lifting structure 25 for lifting the sign pole is connected to the top of the extension structure 24. A clamping hoop 26 for locking the sign pole is fixedly connected to the output end of the lifting structure 25 via a rope. A through groove 28 is provided on one side of the top of the base 1. The length and width of the through groove 28 are both greater than the diameter of the circle formed by the two clamping plates 205. Universal wheels 27 are connected to the four corners of the bottom of the base 1. The supporting mechanism 3 includes an adjusting part 301, a supporting part 302, and a lifting part 303, and is specifically designed as follows:
[0052] The adjustment part 301 includes a mounting plate 3011, which is connected to one side of the base 1. The top of the mounting plate 3011 has a slot 3012. Bearings are provided through the front and back of the mounting plate 3011. A lead screw 3013 is provided in the slot 3012 and located in the bearing. Two first threaded sleeves 3014 are symmetrically sleeved on the outside of the lead screw 3013.
[0053] The support part 302 includes a sleeve 3021 fixedly connected to the top of the first threaded sleeve 3014. The top of the sleeve 3021 has a cavity. The top of the sleeve 3021 is fixedly connected to an annular top cover 3022. The top of the top cover 3022 is slidably connected to a slide rod 3023 located in the cavity. The top of the slide rod 3023 is fixedly connected to a support plate 3024 for supporting the sign pole.
[0054] The lifting part 303 includes a sliding plate 3032 fixedly sleeved on the outside of the sliding rod 3023 and located in the cavity. The sliding plate 3032 is slidably connected to the sleeve 3021. A first spring 3033 is fixedly connected to the top of the sliding plate 3032. The end of the first spring 3033 away from the sliding plate 3032 is fixedly connected to the bottom of the top cover 3022. The first spring 3033 is sleeved on the outside of the sliding rod 3023. A square groove 3031 is opened through one side of the top of the sleeve 3021. A support rod 3034 is fixedly connected to one side of the sliding plate 3032. A first wedge block 3035 is fixedly connected to one end of the support rod 3034. Two fixing rods 3036 are symmetrically fixedly connected to one side inside the groove 3012. A second wedge block 3037 is fixedly connected to the top of the fixing rod 3036.
[0055] When the workers hoist the signpost, the middle part of the signpost is clamped and fixed by the clamping hoist 26. The lifting structure 25 and the extension structure 24 are used to horizontally hoist the signpost into the clamping mechanism 2 to clamp and fix the bottom end that will be connected to the ground. Then, the screw 3013 is rotated to drive the two first threaded sleeves 3014 to move towards each other, which in turn drives the sleeves 3021 in the two supporting parts 302 to move closer to each other. The sleeves 3021 drive the first wedge block 3035 and the second wedge block 3037 on them to slide against each other. The pressure pushes the first wedge block 3035 upward along the square groove 3031 on the sleeve 3021, thereby driving the slide plate 3032, slide rod 3023, and support plate 3024 to rise until the support plate 3024 contacts the bottom of the sign post to support it, keeping the sign post horizontal and preventing it from tilting or rotating. Then, the clamping hoop 26 is connected to the end of the sign post away from the ground, and the sign post is lifted from a horizontal state to a vertical state for installation through the lifting structure 23, extension structure 24, and lifting structure 25. That is, the clamping mechanism 2 can clamp one end of the sign post, and the support mechanism 3 can support the bottom of the sign post, thereby ensuring that the sign post remains horizontal.
[0056] Reference Figure 2 and Figure 3 The adjustment unit 301 further includes: a first U-shaped plate 3015 fixedly connected to the front of the mounting plate 3011, a motor 3016 installed inside the first U-shaped plate 3015, the motor 3016 being connected to an external controller and a power supply, the motor 3016 being existing technology and not described in detail here, the output end of the motor 3016 being connected to one end of the lead screw 3013 for transmission, a sliding groove 8 being provided on the inner side of the bottom of the mounting plate 3011, four sliders 9 being slidably connected in the sliding groove 8, and a connecting rod 10 being fixedly connected to the top of the sliders 9, wherein the top ends of two connecting rods 10 are fixedly connected to the bottom of two first threaded sleeves 3014.
[0057] By setting the slider 9 and the connecting rod 10, the first threaded sleeve 3014 can be limited to move.
[0058] Reference Figure 2 and Figure 3 The adjustment part 301 also specifically includes: a first anti-slip pad 3025 fixedly connected to the top of the support plate 3024 to prevent the sign pole from sliding. The top of the first anti-slip pad 3025 is provided with multiple anti-slip patterns, which can increase the protection of the support plate 3024 and extend the service life of the support plate 3024.
[0059] Reference Figure 1 and Figure 8The clamping mechanism 2 includes two symmetrically arranged fixed plates 201 fixedly connected to the top of the base 1. A circular groove is opened through the front of the fixed plate 201. A rotating ring 202 is rotatably connected in the circular groove. A threaded cylinder 203 is fixedly connected inside the rotating ring 202. A threaded rod 204 is threadedly connected inside the threaded cylinder 203. A clamping plate 205 is rotatably connected to one end of the threaded rod 204. The top of the first anti-slip pad 3025 is lower than the bottom of the clamping plate 205. A crossbar 206 that is slidably connected to the rotating ring 202 is fixedly connected to the top of the clamping plate 205 near the threaded rod 204.
[0060] Rotating the threaded rod 204 can move the clamping plate 205, causing the two clamping plates 205 to move closer to each other and fit together, thereby clamping the two clamping plates 205 to one end of the sign post and fixing the bottom end of the sign post.
[0061] Reference Figure 1 and Figure 2 The base 1 has a second U-shaped plate 4 fixedly connected to one side of the front and back. The second U-shaped plate 4 has an adjusting rod 5 that is slidably connected to the base 1. Both adjusting rods 5 are fixedly connected to the mounting plate 3011. The front of the adjusting rod 5 has multiple threaded grooves 6. The side of the second U-shaped plate 4 away from the base 1 is threaded with a screw 7 located in the threaded groove 6.
[0062] By unscrewing screw 7 to release the lock of adjusting rod 5, and then moving adjusting rod 5 to move mounting plate 3011, the entire supporting mechanism 3 can be moved. After the supporting mechanism 3 is moved to the appropriate position, screw 7 is tightened to fix the position of adjusting rod 5 and mounting plate 3011. The supporting position of supporting mechanism 3 can be adjusted, and the support mechanism 3 can be prevented from moving when supporting the other end of the sign pole.
[0063] In the above embodiment, after the clamping mechanism 2 clamps the bottom end of the sign post, the screw 7 needs to be manually unscrewed and the position of the adjusting rod 5 needs to be moved so that the supporting mechanism 3 can be adjusted to a suitable position. Then, the motor 3016 is started to further adjust the position of the supporting plate 3024 to support the sign post. The operation process is cumbersome and time-consuming, and the adjustment of the support position of the supporting mechanism 3 depends on the experience of the operator. When the operator is inexperienced and operates improperly, one end of the sign post may still come into contact with the ground and rub against it. In order to enable the adjusting rod 5 to achieve automatic adjustment, the adjusting rod 5 is slidably connected to both sides of the inside of the base 1, and a third spring is fixed between the adjusting rod 5 and the base 1. The adjusting rod 5 and the base 1 are respectively embedded with a magnet and an electromagnet that repel each other. By adjusting the magnetic induction intensity of the electromagnet, the sliding distance of the adjusting rod 5 is changed, so that the supporting plate 3024 moves to one end of the sign post.
[0064] After the clamping mechanism 2 clamps the bottom end of the sign post, the electromagnet is energized by the external controller and becomes magnetic. Under the action of the repulsive magnetic force, the adjusting rod 5 is driven to slide outward against the elastic force of the third spring, pushing the mounting plate 3011 to move to a suitable position to support the other end of the sign post. The current flowing into the electromagnet can be adjusted according to the length of the sign post to adjust the magnetic induction intensity of the electromagnet, so that the magnetic force between the adjusting rod 5 and the base 1 changes, thereby adjusting the sliding distance of the adjusting rod 5, so that the support plate 3024 can be better applied to support sign posts of different specifications.
[0065] Furthermore, in order to enable the adjusting rod 5 to automatically adjust the sliding distance according to the length of the marker rod, an infrared emitting module and an infrared receiving module are respectively provided at one end of the extension structure 24 and at corresponding positions on the adjusting part 301. The electromagnet responds to the received signal of the infrared receiving module and controls the magnetic induction intensity of the electromagnet to continue to increase.
[0066] After the clamping mechanism 2 clamps the bottom end of the marker pole, the electromagnet is energized by an external controller, and the current gradually increases. The pattern of current increase can be simulated using linear or logarithmic functions as needed, allowing the adjusting rod 5 to gradually slide out of the base 1. This prevents the adjusting rod 5 from suddenly sliding out due to a large instantaneous magnetic force, which could damage components or injure personnel. Since the clamping hoop 26 is fitted in the middle of the marker pole at this time, and the extension length of the extension structure 24 is about half the length of the marker pole, when the infrared receiving module receives the signal from the infrared transmitting module, it indicates that the adjusting part 301 has moved outward to a position corresponding to the extension length of the extension structure 24. At this time, it can be controlled... The adjusting rod 5 continues to move outward, and the outward movement length is close to the current movement distance. Considering that the clamping hoop 26 may not be accurately fitted into the middle position of the sign post, especially when the clamping hoop 26 is fitted and clamped on the side close to the top of the sign post, the continued outward movement of the adjusting rod 5 must be controlled within the current movement distance to ensure that the supporting plate 3024 can support the top of the sign post. Therefore, when adjusting the continued outward movement of the adjusting rod 5 by controlling the increment of the electromagnetic induction intensity, for example, the increment of the magnetic induction intensity is controlled to not exceed half of the current magnetic induction intensity value, leaving enough margin so that the sliding distance of the adjusting part 301 will not exceed the length of the sign post under any circumstances.
[0067] Reference Figure 6 and Figure 7Mounting rods 14 are slidably connected to the four corners of the bottom of mounting plate 3011. A fixing ring 15 is fixedly connected to the top of mounting rod 14. A fourth wedge block 16 is fixedly connected to the top of fixing ring 15. Two second threaded sleeves 11 are symmetrically threaded on the outside of screw rod 3013. The tops of two other connecting rods 10 are fixedly connected to the bottoms of the two second threaded sleeves 11. Limiting rods 12 are fixedly connected to both sides of the top of the second threaded sleeves 11. A third wedge block 13 is fixedly connected to one end of the limiting rod 12. A second spring 17 is fixedly connected to the bottom of fixing ring 15, which is sleeved on the outside of mounting rod 14 and fixedly connected to the top of mounting plate 3011.
[0068] Reference Figure 6 and Figure 7 The bottom end of the mounting rod 14 is fixedly connected to a collar 18. Multiple L-shaped support legs 19 are fixedly connected to the outer side of the collar 18 in a circular array. One end of the support leg 19 is fixedly connected to a base plate 20. A second anti-slip pad 21 is fixedly connected to the bottom of the base plate 20.
[0069] While the lead screw 3013 rotates, it drives the two first threaded sleeves 3014 to move towards each other, and also drives the two second threaded sleeves 11 to move towards each other. During the movement, the third wedge block 13 squeezes the fourth wedge block 16, thereby lowering and moving the support leg 19 and the base plate 20 until the base plate 20 contacts the ground to support the mounting plate 3011 and further prevent the mounting plate 3011 from shifting. By setting the second anti-slip pad 21, the second anti-slip pad 21 can contact the ground, thereby increasing the friction between the second anti-slip pad 21 and the ground.
[0070] It should be noted that the extension structure 24, lifting structure 25 and jacking structure 23 are all the same as the structure of the road sign pole hoisting and installation mechanism for highway construction provided in the document with technical publication number CN114906735A, and will not be described in detail here.
[0071] The implementation principle of a road sign pole hoisting and installation mechanism according to an embodiment of this application is as follows: When installing the sign pole, the clamping hoist 26 is fitted onto the outside of the sign pole. Using the lifting structure 25 and the extension structure 24, the sign pole is horizontally hoisted between two clamping plates 205. Then, the threaded rod 204 is rotated so that the two clamping plates 205 come closer to each other and fit together, thereby clamping the two clamping plates 205 at one end of the sign pole.
[0072] Then, unscrew screw 7 and move adjusting rod 5. Moving adjusting rod 5 moves mounting plate 3011, thus moving the entire support mechanism 3. Once the support mechanism 3 is in the appropriate position, tighten screw 7 to fix the positions of adjusting rod 5 and mounting plate 3011. At this point, start motor 3016 via external controller, driving lead screw 3013 to rotate. Rotation of lead screw 3013 causes the two first threaded sleeves 3014 to move closer to each other, thus causing the two support parts 302 to also move closer to each other. When the support part 302 moves, it can drive the sliding plate 3032, the support rod 3034, and the first wedge block 3035 to move as well. The cooperation of the second wedge block 3037 and the first wedge block 3035 then drives the sliding plate 3032 to rise, which in turn drives the sliding rod 3023, the support plate 3024, and the first anti-slip pad 3025 to rise. This causes the two first anti-slip pads 3025 to come closer together and fit against each other, while also contacting the bottom of the signpost, thus supporting the bottom of the signpost.
[0073] Simultaneously, when the lead screw 3013 rotates, it can drive the two second threaded sleeves 11 to move towards each other. The movement of the second threaded sleeves 11 can drive the limit rod 12 and the third wedge block 13 to move. At this time, the third wedge block 13 moves to squeeze the fourth wedge block 16, causing the fourth wedge block 16 to move downward, driving the fixing ring 15 and the mounting rod 14 to move downward, and then driving the collar 18, the support leg 19 and the base plate 20 to move downward until the second anti-slip pad 21 contacts the ground. At this time, the motor 3016 is turned off, the clamping hoop 26 is removed and fitted onto the other end of the sign post, and then the lifting structure 23, the extension structure 24 and the lifting structure 25 are used respectively to make the sign post rotate around the rotating ring 202 as the axis, thereby lifting the sign post from a horizontal state to a vertical state for installation.
