Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment, in particular to a hoisting equipment for a column component. Background Art

[0002] With the rapid development of intelligent transportation systems and urban security systems, road monitoring poles, as critical infrastructure supporting cameras, traffic lights, environmental monitoring equipment, and other equipment, have a significant impact on traffic management and public safety. Traditional manual pole installation methods, limited by height and weight, present low efficiency and high safety risks. The application of mechanized hoisting technology has become the mainstream solution in the industry.

[0003] In the existing technology, a mobile crane (such as a 25-ton crane) is usually used in conjunction with a nylon sling (tensile strength ≥ 10t) for double-point balanced lifting. However, due to the asymmetrical structure of the column components, it is impossible to accurately find the overall center of gravity of the column during lifting to make it vertical so that workers can align the screw holes to fix the column. During installation, workers are required to additionally pull the adjustment rope to keep it in a basically vertical state, but it still cannot achieve an accurate state, and it is very easy to shake, which is also very dangerous.

[0004] The information disclosed in the background technology section of the present invention is only intended to deepen the understanding of the general background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Summary of the Invention

[0005] Based on this, it is necessary to provide a hoisting device for column components to address the problem that current hoisting equipment cannot automatically adjust the hoisting position so that the column reaches a preset state.

[0006] The above purpose is achieved through the following technical solutions:

[0009] Hanging units, the hanging units are provided in two groups, the two groups of hanging units are arranged in parallel and spaced apart, and the hanging units are used to hang the hanging body;

[0010] A linkage mechanism connecting the two groups of suspension units;

[0011] During the hoisting process of the hoisting body, the two groups of the hanging units drive the linkage mechanism to work due to the force difference. The linkage mechanism drives the hanging units with greater force to be fixed, and the hanging units with less force to slide along the hoisting body until the hoisting body reaches a preset balance state.

[0012] Furthermore, it also includes a guide assembly, which includes a guide rope, and the hanging unit includes a hollow hook sleeve and a hook shaft core, and the hanging body includes a cross bar and a vertical bar, and the cross bar and the vertical bar are fixedly connected at a vertical angle, the hollow hook sleeve is slidably connected to the cross bar, and the hook shaft core can be rotatably nested in the hollow hook sleeve, and the guide rope is extended in the axial direction of the cross bar, and the guide rope is connected to the hollow hook sleeves and the hook shaft core of the two groups of hanging units; during the lifting process, the linkage mechanism drives the hollow hook sleeve of the hanging unit with greater force to lock with the guide rope, and the linkage mechanism drives the hollow hook sleeve of the hanging unit with less force to remain in an unlocked state with the guide rope, and the hollow hook sleeve of the hanging unit with less force can slide along the cross bar to adjust the position of the hanging point.

[0013] Furthermore, the linkage mechanism includes a hydraulic control device and a locking unit. When the two groups of hanging units are subjected to different forces, the hydraulic control device on the hanging unit subjected to greater force drives the locking unit to work, so that the hollow hook sleeve and the guide rope are locked; the hydraulic control device on the hanging unit subjected to less force does not drive the locking unit to work, so that the hollow hook sleeve and the guide rope remain unlocked.

[0014] Furthermore, the hydraulic control device includes a hydraulic cylinder shaft and a hydraulic cylinder sleeve, the hydraulic cylinder sleeve is slidably connected to the hydraulic cylinder shaft, and the hydraulic cylinder shaft is fixedly connected to the hook shaft core; a first oil chamber is formed between the inner wall of the hydraulic cylinder sleeve and the inner wall of the hydraulic cylinder shaft, and a second oil chamber is formed between the inner wall of the hydraulic cylinder sleeve and the outer wall of the hydraulic cylinder shaft; the hydraulic control device also includes a first oil pipe and a second oil pipe, and the first oil chambers on the two groups of the hanging units are connected by the first oil pipe; when the two groups of the hook shaft cores are subjected to different forces, the hydraulic cylinder sleeve of the hanging unit subjected to the larger force is connected to the hydraulic chamber The relative sliding of the cylinder shaft reduces the pressure in the first oil chamber of the hanging unit, and the oil in the first oil chamber of the hanging unit with less force is squeezed into the first oil chamber of the hanging unit with greater force through the first oil pipe. The locking unit of the hanging unit with less force keeps the hollow hook sleeve and the guide rope unlocked; at the same time, the area of ​​the second oil chamber of the hanging unit with greater force is reduced, and the oil in the second oil chamber is squeezed into the locking unit. The hanging unit with greater force drives the locking unit to lock the hollow hook sleeve and the guide rope.

[0015] Furthermore, the locking unit includes a rope lock and a rope lock bracket, the rope lock is fixedly connected to the hollow hook sleeve, the rope lock is communicated with the second oil pipe, and the rope lock bracket is rotatably connected to the hollow hook sleeve; the hydraulic cylinder sleeve and the hydraulic cylinder shaft of the hanging unit that is subjected to greater force slide relative to each other, and the oil in the second oil chamber is squeezed to the rope lock through the second oil pipe, and the rope lock drives the rope lock bracket to lock the guide rope and the hollow hook sleeve.

[0016] Furthermore, the guide assembly also includes a fixing frame, a stranded wire housing and a tensioning unit. The fixing frame is fixedly connected to the vertical rod, the stranded wire housing is fixedly connected to the fixing frame, the stranded wire housing is used to limit the tensioning unit from being separated from the vertical rod, and the tensioning unit is used to ensure that the guide rope is always in a tensioned state.

[0017] Furthermore, the tensioning unit also includes a winding wheel, a gear, a control handle and a ratchet locking plate. The control handle is provided with a transmission gear, the gear is engaged with the transmission gear, the ratchet locking plate abuts the transmission gear, the gear is coaxially fixedly connected to the winding wheel, and one end of the guide rope is connected to the winding wheel; the control handle drives the winding wheel to rotate to tighten the guide rope through the engagement of the gear and the transmission gear, and the ratchet locking plate only allows the transmission gear to rotate in one direction.

[0018] Furthermore, the tensioning unit also includes a locking fixing plate and a tension spring, the locking fixing plate and the ratchet locking plate are fixedly connected, one end of the tension spring is connected to the locking fixing plate, and the other end is connected to the stranded wire housing; the elastic force of the tension spring makes the locking fixing plate always tend to be close to the lower end of the stranded wire housing, so that the ratchet locking plate is always in contact with the transmission gear, and through the engagement of the gear and the transmission gear, the stranded wire wheel is only allowed to rotate in one direction.

[0019] Furthermore, the tensioning unit also includes a tensioning frame, which is coaxially arranged with the cross bar and can slide along the axial direction of the cross bar to adjust its position. The tensioning frame is connected to the other end of the guide rope for tensioning the guide rope.

[0020] Furthermore, a pad is provided on the hollow hook sleeve, and the pad is used to reduce the friction between the hollow hook sleeve and the cross bar when sliding.

During the hoisting process of the hanging units on the hoisting body, when a force difference occurs between the two sets of hanging units due to the offset of the column's center of gravity, the linkage mechanism automatically drives the hanging unit with the greater force to be fixed, while the hanging unit with the lesser force slides along the hoisting body to adjust its position until the hoisting body reaches a preset vertical equilibrium state. The present invention achieves automatic adjustment of the hoisting body during the hoisting process, significantly improving installation accuracy and safety, and is suitable for hoisting operations of asymmetric components such as road monitoring columns.

Therefore, they should not be construed as limitations on the present invention.

[0041] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0042] Refer to the following Figures 1 to 11 The hoisting equipment for column components provided by an embodiment of the present invention is described.

[0043] like Figures 1 to 3 As shown, the hoisting equipment for column components provided by the embodiment of the present invention is particularly suitable for hoisting column components. Of course, it can also be used for hoisting processing under other working conditions under appropriate circumstances.

[0044] Specifically, the hoisting equipment of the column component includes a hoisting body 100. As a hoisting object, the hoisting body 100 includes a cross bar 102 and a vertical bar 101. The cross bar 102 and the vertical bar 101 have regular cross-sections in the radial direction, and the cross bar 102 and the vertical bar 101 are fixedly connected at a vertical angle. The diameter of the cross bar 102 gradually increases along its own axis in the direction close to the vertical bar 101, and the diameter of the vertical bar 101 gradually increases along its own axis in the direction away from the cross bar 102. Before the hoisting begins, the vertical bar 101 and the cross bar 102 are both in an initial state of being in contact with the ground. At this time, the center of gravity of the hoisting body 100 is at the connection between the two and is closer to the position of the vertical bar 101 with a larger diameter. Therefore, if the center of gravity of the hoisting body 100 cannot be accurately found during the hoisting, the hoisting work will easily tilt and shake, making it impossible to achieve a precise installation state.

[0045] Therefore, the hoisting equipment of the column component also includes a hanging unit 200 and a linkage mechanism. The hanging unit 200 is used to hoist the crossbar 102 and the vertical bar 101, and is provided in two groups. The two groups of hanging units 200 are arranged in parallel and spaced apart. Both groups of hanging units 200 are slidably arranged on the crossbar 102, and the two groups of hanging units 200 are connected by a linkage mechanism. Specifically, in the initial state, the vertical bar 101 and the crossbar 102 lie flat on the ground. The crossbar 102 is hoisted by the hanging unit 200. Since the crossbar 102 and the vertical bar 101 are fixedly connected, the vertical bar 101 is also hoisted, thereby achieving overall hoisting. Since the initial position of the hanging unit 200 on the horizontal bar 102 before hoisting is not accurate, and the center of gravity of the hoisting body 100 is at the connection between the two and closer to the vertical bar 101, the hanging unit 200 close to the vertical bar 101 is subject to a greater gravity of the hoisting body 100, and the hanging unit 200 far from the vertical bar 101 is subject to a smaller gravity of the hoisting body 100. After hoisting, the hoisting body 100 is tilted as a whole: the horizontal bar 102 tilts upward, and the vertical bar 101 tilts to the left, that is, Figure 1The linkage mechanism then controls the suspension unit 200 with the greater force applied to it, immobilizing it. The other suspension unit 200 then slides along the axis of the horizontal bar 102 toward the vertical bar 101, gradually achieving force equilibrium with the fixed suspension unit 200. During this process, the vertical bar 101 gradually becomes perpendicular to the ground, while the horizontal bar 102 gradually becomes parallel to the ground, and the suspension body 100 gradually reaches the predetermined suspension state.

[0046] In one embodiment, the hoisting device of the column component also includes a guide assembly. The guide assembly includes a guide rope 420, which is extended in the axial direction of the crossbar 102. The hanging unit 200 includes a hollow hook sleeve 201, a hook shaft core 202 and a lifting rope, and the hook shaft core 202 can be rotatably nested in the hollow hook sleeve 201. One end of the lifting rope of the two sets of hanging units 200 is connected to the hook on the lifting equipment for providing power, and the lifting rope acts on the hook shaft core 202 and the hollow hook sleeve 201 to lift the crossbar 102 and the vertical rod 101. The hollow hook sleeve 201 is slidably connected to the crossbar 102, and the hollow hook sleeve 201 can slide along the axial direction of the crossbar 102. In addition, notches are provided on the hollow hook sleeve 201 and the hook shaft core 202. The length of the notch on the hollow hook sleeve 201 extends along the circumferential direction of the hollow hook sleeve 201, and the length of the notch on the hook shaft core 202 extends along the circumferential direction of the hook shaft core 202. The guide rope 420 passes through the notches on the hollow hook sleeve 201 and the hook shaft core 202 at the same time.

[0047] Furthermore, when the vertical rod 101 and the horizontal rod 102 are gradually lifted off the ground from a lying state, in order to prevent the hollow hook sleeve 201 from sliding on the horizontal rod 102 and causing a lifting failure, the hook shaft core 202 will rotate relative to the hollow hook sleeve 201 at the initial stage of lifting, and the guide rope 420 passes through the hollow hook sleeve 201 and the hook shaft core 202 through the slot. Therefore, when the hook shaft core 202 and the hollow hook sleeve 201 rotate relative to each other, the lower end of the slot on one side of the hook shaft core 202 and the upper end of the slot on one side of the hollow hook sleeve 201 cooperate with each other to clamp the guide rope 420, thereby fixing the hollow hook sleeve 201 on the guide rope 420, ensuring that the vertical rod 101 and the horizontal rod 102 are lifted smoothly.

[0048] In one embodiment, the linkage mechanism includes a hydraulic control device and a locking unit, and both sets of suspension units 200 are provided with the hydraulic control device and the locking unit. Specifically, when the horizontal bar 102 and the vertical bar 101 are gradually lifted off the ground from a flat position, the hydraulic control device will drive the locking unit on the suspension unit 200 with greater force to lock the guide rope 420 and the hollow hook sleeve 201 due to the force difference between the two sets of suspension units 200. At the same time, during the process of gradually lifting the horizontal bar 102 and the vertical bar 101 from a flat position, the notch of the hook shaft core 202 on the suspension unit 200 with greater force and the notch of the hollow hook sleeve 201 will clamp the guide rope 420, further ensuring that the hollow hook sleeve 201 of the suspension unit 200 remains fixed to the guide rope 420, preventing the hollow hook sleeve 201 from sliding along the axial direction of the horizontal bar 102. During this process, the hydraulic control device of the hanging unit 200, which is subjected to less force, will not drive the locking unit to lock the guide rope 420 and the hollow hook sleeve 201 due to the smaller force. The guide rope 420 is only clamped by the slots of the hook shaft core 202 and the slots of the hollow hook sleeve 201 to prevent the hollow hook sleeve 201 from sliding along the axial direction of the cross bar 102.

[0049] It is worth noting that the structure of the hook shaft core 202 is not a completely circular structure, but a nearly complete semicircular structure. Figure 11 As shown in FIG5 , the radial dimension of the opening of hook shaft core 202 is less than the diameter of hollow hook cover 201. After vertical rod 101 and cross bar 102 are lifted and separated from the ground, hook shaft core 202 rotates in the opposite direction to reset, thereby makes the notch on a side on the hook shaft core 202 and the notch on a side of hollow hook cover 201 no longer clamp guide rope 420. At this moment, because the radial dimension of the opening of hook shaft core 202 is less, in the process of hook shaft core 202 rotating in the opposite direction to reset, hook shaft core 202 is gradually corrected, and the hook shaft core 202 of its hollow hook cover 201 inside is also close to hollow hook cover 201 inwalls.Again because the radial dimension of the opening of hook shaft core 202 is less than the diameter of hollow hook cover 201, so hollow hook cover 201 and hook shaft core 202 form close friction contact and reach fixed state, realize the hoisting of cross bar 102 and vertical rod 101 then.

[0050] After the horizontal bar 102 and vertical bar 101 are lifted off the ground, the hook shafts 202 of the two sets of hanging units 200 rotate in the opposite direction to reset and unlock the guide rope 420. At this time, since the position of the hanging unit 200 subjected to greater force remains unchanged, the force also remains unchanged. Therefore, the hydraulic control device on the hanging unit 200 subjected to greater force still drives its locking unit to lock the guide rope 420, so that the hollow hook sleeve 201 is fixedly connected to the guide rope 420, preventing the hollow hook sleeve 201 from sliding along the axial direction of the horizontal bar 102. When the horizontal bar 102 and the vertical bar 101 are lifted off the ground, the hydraulic control device on the hanging unit 200 with less stress still does not drive the locking unit to lock the hollow hook sleeve 201 with the guide rope 420 due to the less stress. At this time, the notch on one side of the hook shaft core 202 on the hanging unit 200 with less stress and the notch on one side of the hollow hook sleeve 201 no longer clamp the guide rope 420, so the hollow hook sleeve 201 can slide along the guide rope 420 under the action of the lifting rope. Therefore, the hollow hook sleeve 201 on the hanging unit 200 with less stress can slide along the axis direction of the horizontal bar 102 and toward the vertical bar 101, adjusting the position of the hollow hook sleeve 201 on the horizontal bar 102, so that the hanging unit 200 with less stress gradually reaches a force balance with the hanging unit 200 with greater stress, and then the horizontal bar 102 and the vertical bar 101 gradually reach a predetermined lifting state.

[0051] In one embodiment, the hydraulic control device includes a hydraulic cylinder shaft 301 and a hydraulic cylinder sleeve 302. The hydraulic cylinder sleeve 302 is slidably connected to the hydraulic cylinder shaft 301, and the hydraulic cylinder shaft 301 is fixedly connected to the hook shaft core 202. A first oil chamber 331 is formed between the inner wall of the hydraulic cylinder sleeve 302 and the inner wall of the hydraulic cylinder shaft 301, and a second oil chamber 332 is formed between the inner wall of the hydraulic cylinder sleeve 302 and the outer wall of the hydraulic cylinder shaft 301. In addition, the hydraulic control device also includes a first oil pipe 321 and a second oil pipe 322. The hydraulic cylinder sleeve 302 is provided with a first oil port 311 and a second oil port 312. The first oil pipe 321 is connected to the first oil port 311, and the second oil pipe 322 is connected to the second oil port 312.

[0052] In one embodiment, the locking unit includes a rope lock 305 and a rope lock bracket 306. The rope lock 305 is fixedly connected to the hollow hook sleeve 201. The second oil chamber 332 is connected to the rope lock 305 via a second oil pipe 322, and the first oil chambers 331 on the two sets of hanging units 200 are connected via a first oil pipe 321.

[0053] Specifically, during the hoisting process, the hoisting rope is connected to the hydraulic cylinder sleeve 302, which acts on the hollow hook sleeve 201 and the hook shaft core 202 through the hydraulic cylinder sleeve 302, thereby realizing the hoisting operation. When the two sets of hook shaft cores 202 are subjected to different forces, the hydraulic cylinder sleeve 302 on the hanging unit 200 with the larger force slides upward, that is, Figure 7The vertical displacement of the hydraulic cylinder shaft 301 causes a decrease in the pressure of the first oil chamber 331 of the suspension unit 200 subjected to greater force. Consequently, due to the pressure difference, the oil in the first oil chamber 331 of the suspension unit 200 subjected to less force is squeezed through the first oil pipe 321 into the first oil chamber 331 of the suspension unit 200 subjected to greater force. Meanwhile, the area of ​​the second oil chamber 332 of the suspension unit 200 subjected to greater force decreases due to the relative sliding between the hydraulic cylinder sleeve 302 and the hydraulic cylinder shaft 301, causing the oil in the second oil chamber 332 of the suspension unit 200 subjected to greater force to be squeezed through the second oil pipe 322 into the rope lock 305. The rope lock 305, driven by the oil, then rotates the rope lock bracket 306 to squeeze the guide rope 420, thereby locking the guide rope 420 to the hollow hook sleeve 201. During this process, the area of ​​the second oil chamber 332 on the hanging unit 200 that is subjected to less force will not decrease, resulting in the oil in the second oil chamber 332 on the hanging unit 200 that is subjected to less force being unable to flow into the rope lock 305, so that the rope lock bracket 306 does not squeeze the guide rope 420, so that the guide rope 420 and the hollow hook sleeve 201 are not locked, so that the hollow hook sleeve 201 can slide along the axial direction of the cross bar 102.

[0054] It is noteworthy that a spring 303 is further provided between the hydraulic cylinder sleeve 302 and the hydraulic cylinder shaft 301. When the hoisting body 100 reaches a preset state and the vertical rod 101 is fixed to the ground, the hoisting rope is removed and the elastic force of the spring 303 drives the hydraulic cylinder sleeve 302 to reset.

[0055] In one embodiment, the guide assembly further includes a fixing frame 401, a stranded wire housing 404, and a tensioning unit. The fixing frame 401 is fixedly mounted on the vertical rod 101, and the stranded wire housing 404 is fixedly connected to the fixing frame 401. The stranded wire housing 404 is used to prevent the tensioning unit from being separated from the lifting body 100. The tensioning unit is used to ensure that the guide rope 420 is always in a tensioned state to ensure smooth sliding of the hollow hook sleeve 201.

[0056] In one embodiment, the tensioning unit further includes a winding wheel 403, a gear 405, a control handle 402, and a ratchet locking plate 406. The control handle 402 is provided with a transmission gear 413, wherein the transmission gear 413 is meshed with the gear 405, the ratchet locking plate 406 abuts against the transmission gear 413, and the gear 405 is coaxially fixedly connected to the winding wheel 403. In addition, the tensioning unit further includes a tensioning frame 410, which is slidably connected to the cross bar 102 and is provided with a fixing ring 412. The inner wall of the tensioning frame 410 in contact with the cross bar 102 is provided with rollers 411. One end of the guide rope 420 is connected to the winding wheel 403, and the other end is connected to the tensioning frame 410 via the fixing ring 412. Specifically, the tensioning frame 410 is inserted from the end of the cross bar 102 with a smaller diameter and slides along the axis of the cross bar 102 via the rollers 411. Because its diameter is fixed, it can be stably fixed on the crossbar 102 after reaching the appropriate position. Subsequently, the operator rotates the control handle 402, and the gear 405 is engaged with the transmission gear 413 to drive the winding wheel 403 to rotate, thereby achieving the tightening of the guide rope 420.

[0057] In one embodiment, the tensioning unit further includes a locking plate 407 and a tension spring 408. The locking plate 407 is fixedly connected to the ratchet locking plate 406. One end of the tension spring 408 is connected to the locking plate 407, and the other end is connected to the strand housing 404. During the rotation of the strand wheel 403, the elastic force of the tension spring 408 causes the locking plate 407 to always tend to approach the lower end of the strand housing 404, so that the ratchet locking plate 406 remains in contact with the transmission gear 413, thereby preventing the guide rope 420 from rotating in the opposite direction and ensuring that the guide rope 420 is tensioned. Therefore, the ratchet locking plate 406 restricts the bidirectional rotation of the transmission gear 413, allowing only unidirectional rotation of the transmission gear 413. The meshing of the gear 405 and the transmission gear 413 ensures unidirectional rotation of the strand wheel 403, ensuring that the guide rope 420 is always in a tensioned state, thereby ensuring smooth sliding of the hollow hook sleeve 201.

[0058] In one embodiment, a smooth-surfaced pad 304 is provided on the inner side of the hollow hook sleeve 201 near the crossbar 102. When the hollow hook sleeve 201 slides on the crossbar 102, the pad 304 reduces friction, thereby alleviating wear and tear between the hollow hook sleeve 201 and the crossbar 102 and protecting the durability of the components.

[0059] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
