Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment, and particularly to a hoisting equipment for column members. Background Art

[0002] With the rapid development of intelligent transportation systems and urban security systems, road monitoring columns, as key infrastructure for carrying equipment such as cameras, signal lights, and environmental monitoring, their installation quality directly affects traffic management and public safety. The traditional manual installation method of columns is limited by height and weight, with problems such as low efficiency and high safety risks. The application of mechanized hoisting technology has become the mainstream solution in the industry.

[0003] In the prior art, an automobile crane (such as a 25-ton crane) is usually used in combination with a nylon sling (tensile strength ≥ 10t) for double-hanging-point balanced hoisting. However, due to the asymmetric structure of the column member, it is impossible to accurately find the overall center of gravity of the column during hoisting to make it vertical for workers to align the screw holes and fix the column. During installation, workers need to additionally pull the adjustment rope to make it in a basically vertical state, but it still cannot reach a precise state, is very easy to shake, and is very dangerous.

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

[0005] Based on this, in view of the problem that the existing hoisting equipment cannot automatically adjust the hoisting position to make the column reach a preset state, it is necessary to provide a hoisting equipment for column members.

[0006] The above object is achieved by the following technical solutions: A hoisting equipment for column members, comprising: A hoisting main body; A hanging unit, two groups of hanging units are provided, and the two groups of hanging units are arranged in parallel at intervals. The hanging unit is used for hoisting the hoisting main body; A linkage mechanism, the linkage mechanism connects the two groups of hanging units; During the hoisting process of the hoisting main body, the two groups of hanging units drive the linkage mechanism to work due to the force difference. The linkage mechanism drives the hanging unit with a larger force to be fixed, and the hanging unit with a smaller force slides along the hoisting main body until the hoisting main body reaches a preset balanced state.

[0007] Further, it further includes a guiding component, the guiding component includes a guiding rope, the hanging unit includes a hollow hook sleeve and a hook shaft core, the hoisting main body includes a cross bar and a vertical bar, 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, the hook shaft core is rotatably nested in the hollow hook sleeve, the guiding rope is arranged to extend in the axial direction of the cross bar, and the guiding rope is connected to the hollow hook sleeves and the hook shaft cores of two groups of the hanging units; during hoisting, the linkage mechanism drives the hollow hook sleeve of the hanging unit with a greater force to be locked with the guiding rope, and the linkage mechanism drives the hollow hook sleeve of the hanging unit with a smaller force to remain in an unlocked state with the guiding rope, and the hollow hook sleeve of the hanging unit with a smaller force can slide along the cross bar to adjust the position of the hanging point.

[0008] Further, the linkage mechanism includes a hydraulic control device and a locking unit. When the forces on the two groups of hanging units are different, the hydraulic control device on the hanging unit with a greater force drives the locking unit to work, so that the hollow hook sleeve is locked with the guiding rope; the hydraulic control device on the hanging unit with a smaller force does not drive the locking unit to work, so that the hollow hook sleeve remains in an unlocked state with the guiding rope.

[0009] Further, 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 further includes a first oil pipe and a second oil pipe, and the first oil chambers on two groups of hanging units are connected through the first oil pipe; when the forces on the two groups of hook shaft cores are different, the hydraulic cylinder sleeve and the hydraulic cylinder shaft of the hanging unit with a greater force slide relative to each other, so that the pressure in the first oil chamber of the hanging unit decreases, and the oil in the first oil chamber of the hanging unit with a smaller force is squeezed into the first oil chamber of the hanging unit with a greater force through the first oil pipe, and the locking unit of the hanging unit with a smaller force keeps the hollow hook sleeve in an unlocked state with the guiding rope; at the same time, the area of the second oil chamber of the hanging unit with a greater force decreases, and the oil in the second oil chamber is squeezed into the locking unit, and the hanging unit with a greater force drives the locking unit to lock the hollow hook sleeve with the guiding rope.

[0010] Furthermore, the locking unit includes a rope locking device and a rope locking bracket. The rope locking device is fixedly connected to the hollow hook sleeve. The rope locking device is communicated with the second oil pipe. The rope locking bracket is rotatably connected to the hollow hook sleeve. The hydraulic cylinder sleeve of the hanging unit with a greater force slides relative to the hydraulic cylinder shaft. The oil in the second oil chamber is squeezed into the rope locking device through the second oil pipe. The rope locking device drives the rope locking bracket to lock the guiding rope to the hollow hook sleeve.

[0011] Furthermore, the guiding assembly further includes a fixing frame, a wire stranding housing, and a tensioning unit. The fixing frame is fixedly connected to the vertical rod. The wire stranding housing is fixedly connected to the fixing frame. The wire stranding housing is used to prevent the tensioning unit from detaching from the vertical rod. The tensioning unit is used to ensure that the guiding rope is always in a tensioned state.

[0012] Furthermore, the tensioning unit further includes a wire stranding wheel, a gear, a control handle, and a ratchet locking piece. A transmission gear is arranged on the control handle. The gear meshes with the transmission gear. The ratchet locking piece abuts against the transmission gear. The gear is coaxially and fixedly connected to the wire stranding wheel. One end of the guiding rope is connected to the wire stranding wheel. The control handle drives the wire stranding wheel to rotate to tighten the guiding rope through the meshing of the gear and the transmission gear. The ratchet locking piece only allows the transmission gear to rotate in one direction.

[0013] Furthermore, the tensioning unit further includes a locking fixing piece and a tension spring. The locking fixing piece is fixedly connected to the ratchet locking piece. One end of the tension spring is connected to the locking fixing piece, and the other end is connected to the wire stranding housing. The elastic force of the tension spring makes the locking fixing piece always tend to be close to the lower end of the wire stranding housing, so that the ratchet locking piece always abuts against the transmission gear. Through the meshing of the gear and the transmission gear, the wire stranding wheel is only allowed to rotate in one direction.

[0014] Furthermore, the tensioning unit further includes a tensioning frame. The tensioning frame is coaxially arranged with the cross bar. The tensioning frame can slide and adjust its position along the axis direction of the cross bar. The tensioning frame is connected to the other end of the guiding rope and is used to tension the guiding rope.

[0015] Furthermore, a cushion block is arranged on the hollow hook sleeve. The cushion block is used to reduce the friction generated between the hollow hook sleeve and the cross bar during sliding.

[0016] The beneficial effects of the present invention are: The present invention provides a hoisting device for a column member, which includes a hoisting main body, two groups of hanging units arranged in parallel at intervals, and a linkage mechanism. During the hoisting process of the hoisting main body by the hanging units, when there is a force difference between the two groups of hanging units due to the offset of the center of gravity of the column, the linkage mechanism automatically drives the hanging unit with a larger force to be fixed, and the hanging unit with a smaller force slides along the hoisting main body to adjust its position until the hoisting main body reaches a preset vertical balance state. The present invention realizes the automatic adjustment of the hoisting main body during the hoisting process, significantly improves the installation accuracy and safety, and is applicable to the hoisting operation of asymmetric members such as road monitoring columns.

[0022] Next, refer to Figures 1 to 11 Describe the hoisting equipment for the column member provided by the embodiment of the present invention.

[0023] As Figures 1 to 3As shown, the hoisting device for the column member provided by the embodiment of the present invention is particularly suitable for hoisting the column member. Of course, it can also be used for hoisting treatment under other operating conditions under appropriate circumstances.

[0024] Specifically, the hoisting device for the column member includes a hoisting main body 100. The hoisting main body 100, as the hoisting object, includes a cross bar 102 and a vertical bar 101. The cross section of the cross bar 102 and the vertical bar 101 in the radial direction is a regular shape, and the cross bar 102 and the vertical bar 101 are fixedly connected at a right angle. The diameter of the cross bar 102 gradually increases along its own axis towards the direction close to the vertical bar 101, and the diameter of the vertical bar 101 gradually increases along its own axis towards the direction away from the cross bar 102. Before starting hoisting, both the vertical bar 101 and the cross bar 102 are in the initial state of being in contact with the ground. At this time, the center of gravity of the hoisting main body 100 is at the connection of the two and closer to the position of the vertical bar 101 with a larger diameter. Therefore, if the center of gravity of the hoisting main body 100 cannot be accurately found during hoisting, the hoisting work will be prone to tilting and shaking, making the installation unable to reach the precise state.

[0025] Therefore, the hoisting device for the column member further includes a hanging unit 200 and a linkage mechanism. The hanging unit 200 is used to hoist the cross bar 102 and the vertical bar 101, and is set in two groups. The two groups of hanging units 200 are arranged in parallel at intervals. The two groups of hanging units 200 are both slidably arranged on the cross bar 102, and the two groups of hanging units 200 are connected through a linkage mechanism. Specifically, in the initial state, the vertical bar 101 and the cross bar 102 lie flat on the ground. The cross bar 102 is hoisted by the hanging unit 200. Since the cross bar 102 and the vertical bar 101 are fixedly connected, the vertical bar 101 is also hoisted accordingly, thus realizing the overall hoisting. Since the initial position of the hanging unit 200 on the cross bar 102 is not accurately placed before hoisting, and the center of gravity of the hoisting main body 100 is at the connection of the two and closer to the position of the vertical bar 101, the hanging unit 200 closer to the vertical bar 101 is subjected to a greater gravity of the hoisting main body 100, and the hanging unit 200 farther from the vertical bar 101 is subjected to a smaller gravity of the hoisting main body 100. After the hoisting main body 100 is hoisted, the whole is in an inclined state: the cross bar 102 is tilted upward, and the vertical bar 101 is tilted to the left, that is Figure 1 in the up and down and left and right directions in. Then, when there is a difference in the forces on the two groups of hanging units 200, the linkage mechanism controls the hanging unit 200 with a greater force to remain stationary, and the other group of hanging units 200 slides along the axis of the cross bar 102 towards the direction close to the vertical bar 101 to adjust the position, and gradually reaches a force balance with the fixed hanging unit 200. During this process, the vertical bar 101 gradually becomes perpendicular to the ground, the cross bar 102 gradually becomes parallel to the ground, and the hoisting main body 100 gradually reaches the predetermined hoisting state.

[0026] In one embodiment, the hoisting device of the column member further includes a guiding assembly. The guiding assembly includes a guiding rope 420 which is arranged to extend in the axial direction of the cross bar 102. The hanging unit 200 includes a hollow hook sleeve 201, a hook shaft core 202 and a hoisting rope. The hook shaft core 202 is rotatably nested within the hollow hook sleeve 201. One end of the hoisting ropes of two groups of the hanging units 200 is connected to the hook on the hoisting device for providing power. The hoisting ropes act on the hook shaft core 202 and the hollow hook sleeve 201, and then lift the cross bar 102 and the vertical bar 101. The hollow hook sleeve 201 is slidably connected to the cross bar 102 and can slide along the axial direction of the cross bar 102. In addition, notches are provided on both 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 guiding rope 420 passes through the notches on both the hollow hook sleeve 201 and the hook shaft core 202 at the same time.

[0027] Further, when gradually lifting the vertical bar 101 and the cross bar 102 from the lying state off the ground, to prevent the hollow hook sleeve 201 from sliding on the cross bar 102 and causing the hoisting to fail, the hook shaft core 202 will rotate relative to the hollow hook sleeve 201 at the initial stage of hoisting. Since the guiding rope 420 passes through the notches on both the hollow hook sleeve 201 and the hook shaft core 202, when the hook shaft core 202 rotates relative to the hollow hook sleeve 201, the lower end of the notch on one side of the hook shaft core 202 cooperates with the upper end of the notch on one side of the hollow hook sleeve 201 to clamp the guiding rope 420, thereby fixing the hollow hook sleeve 201 on the guiding rope 420 and ensuring the smooth hoisting of the vertical bar 101 and the cross bar 102.

[0028] In one embodiment, the linkage mechanism includes a hydraulic control device and a locking unit. Hydraulic control devices and locking units are provided on both sets of hanging units 200. Specifically, when the cross bar 102 and the vertical bar 101 are gradually lifted off the ground from the lying state, due to the force difference between the two sets of hanging units 200, the hydraulic control device will drive the locking unit on the hanging unit 200 with a greater force to lock the guide rope 420 and the hollow hook sleeve 201. At the same time, during the process of gradually lifting the cross bar 102 and the vertical bar 101 off the ground from the lying state, the notch of the hook axle core 202 on the hanging unit 200 with a 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 hanging unit 200 is fixed to the guide rope 420 and preventing the hollow hook sleeve 201 from sliding along the axial direction of the cross bar 102. During this process, the hydraulic control device of the hanging unit 200 with a smaller force will not drive the locking unit to lock the guide rope 420 and the hollow hook sleeve 201, and only clamps the guide rope 420 through the notch of the hook axle core 202 and the notch of the hollow hook sleeve 201 to prevent the hollow hook sleeve 201 from sliding along the axial direction of the cross bar 102.

[0029] It should be noted that the structure of the hook axle core 202 is not a complete circular structure, but a nearly complete semi-circular structure. Therefore, as Figure 11 shown, the radial dimension of the opening part of the hook axle core 202 is smaller than the diameter of the hollow hook sleeve 201. After the vertical bar 101 and the cross bar 102 are lifted and separated from the ground, the hook axle core 202 rotates reversely to reset, so that the notch on one side of the hook axle core 202 and the notch on one side of the hollow hook sleeve 201 no longer clamp the guide rope 420. At this time, due to the smaller radial dimension of the opening part of the hook axle core 202, during the reverse rotation and reset process of the hook axle core 202, the hook axle core 202 gradually returns to the correct position, and the hook axle core 202 inside the hollow hook sleeve 201 closely adheres to the inner wall of the hollow hook sleeve 201. Also, because the radial dimension of the opening part of the hook axle core 202 is smaller than the diameter of the hollow hook sleeve 201, a tight frictional contact is formed between the hollow hook sleeve 201 and the hook axle core 202 to reach a fixed state, and then the hoisting of the cross bar 102 and the vertical bar 101 is realized.

[0030] After the cross bar 102 and the vertical bar 101 are lifted off the ground, the hook axles 202 of the two sets of hanging units 200 rotate in the reverse direction to reset and unlock the guiding rope 420. At this time, the position of the hanging unit 200 with a greater force remains unchanged, and the force is also the same. Therefore, the hydraulic control device on the hanging unit 200 with a greater force still drives its locking unit to lock the guiding rope 420, so that the hollow hook sleeve 201 is fixedly connected to the guiding rope 420, preventing the hollow hook sleeve 201 from sliding along the axial direction of the cross bar 102. After the cross bar 102 and the vertical bar 101 are lifted off the ground, the hydraulic control device on the hanging unit 200 with a smaller force still does not drive the locking unit to lock the hollow hook sleeve 201 and the guiding rope 420 due to the smaller force. At this time, the notch on one side of the hook axle 202 and the notch on one side of the hollow hook sleeve 201 on the hanging unit 200 with a smaller force no longer clamp the guiding rope 420. Therefore, the hollow hook sleeve 201 can slide along the guiding rope 420 under the action of the hoisting rope. Therefore, the hollow hook sleeve 201 on the hanging unit 200 with a smaller force can slide along the axis of the cross bar 102 and in the direction close to the vertical bar 101, adjusting the position of the hollow hook sleeve 201 on the cross bar 102, so that the hanging unit 200 with a smaller force gradually reaches a force balance with the hanging unit 200 with a greater force, and further enabling the cross bar 102 and the vertical bar 101 to gradually reach a predetermined hoisting state.

[0031] 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 axle 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 further 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 communicated with the first oil port 311, and the second oil pipe 322 is communicated with the second oil port 312.

[0032] In one embodiment, the locking unit includes a rope locking device 305 and a rope locking bracket 306. The rope locking device 305 is fixedly connected to the hollow hook sleeve 201. The second oil chamber 332 is connected to the rope locking device 305 through the second oil pipe 322, and the first oil chambers 331 on the two sets of hanging units 200 are connected through the first oil pipe 321.

[0033] Specifically, during the hoisting process, the hoisting rope is connected to the hydraulic cylinder sleeve 302, and acts on the hollow hook sleeve 201 and the hook axle 202 through the hydraulic cylinder sleeve 302, thereby realizing the hoisting operation. When the forces on the two hook axles 202 are different, the hydraulic cylinder sleeve 302 on the hanging unit 200 with a greater force slides upward, that is Figure 7In the up-and-down direction, a displacement relative to the hydraulic cylinder shaft 301 is generated, causing the pressure in the first oil chamber 331 of the hanging unit 200 with a greater force to decrease. Then, due to the pressure difference, the oil in the first oil chamber 331 of the hanging unit 200 with a smaller force is squeezed through the first oil pipe 321 into the first oil chamber 331 of the hanging unit 200 with a greater force; on the other hand, the area of the second oil chamber 332 of the hanging unit 200 with a greater force will decrease due to the relative sliding of the hydraulic cylinder sleeve 302 and the hydraulic cylinder shaft 301, causing the oil in the second oil chamber 332 of the hanging unit 200 with a greater force to be squeezed into the rope locking device 305 through the second oil pipe 322. Then, the rope locking device 305 drives the rope locking bracket 306 to rotate under the push of the oil to squeeze the guide rope 420, thereby locking the guide rope 420 with the hollow hook sleeve 201. During this process, the area of the second oil chamber 332 of the hanging unit 200 with a smaller force does not decrease, resulting in the oil in the second oil chamber 332 of the hanging unit 200 with a smaller force being unable to flow into the rope locking device 305, so that the rope locking bracket 306 does not squeeze the guide rope 420, enabling the guide rope 420 and the hollow hook sleeve 201 not to be locked, so that the hollow hook sleeve 201 can slide along the axial direction of the cross bar 102.

[0034] It should be noted that a spring 303 is also provided between the hydraulic cylinder sleeve 302 and the hydraulic cylinder shaft 301. When the hoisting main body 100 reaches the preset state and the vertical rod 101 is fixed to the ground, after removing the hoisting rope, the elastic force of the spring 303 will drive the hydraulic cylinder sleeve 302 to reset.

[0035] In one embodiment, the guiding assembly further includes a fixing frame 401, a stranded wire housing 404 and a tensioning unit. The fixing frame 401 is fixedly arranged 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 detaching from the hoisting main body 100, and the tensioning unit is used to ensure that the guide rope 420 is always in a tensioned state to ensure the smooth sliding of the hollow hook sleeve 201.

[0036] In one embodiment, the tensioning unit further includes a stranded wire wheel 403, a gear 405, a control handle 402, and a ratchet locking piece 406. A transmission gear 413 is provided on the control handle 402, wherein the transmission gear 413 meshes with the gear 405, the ratchet locking piece 406 abuts against the transmission gear 413, and the gear 405 is coaxially and fixedly connected to the stranded wire wheel 403. In addition, the tensioning unit further includes a tensioning frame 410. The tensioning frame 410 is slidably connected to the cross bar 102, is provided with a fixing ring 412, and rollers 411 are provided on the inner wall of the tensioning frame 410 in contact with the cross bar 102. One end of the guiding rope 420 is connected to the stranded wire wheel 403, and the other end is connected to the tensioning frame 410 through the fixing ring 412. Specifically, the tensioning frame 410 is sleeved from the thinner end of the cross bar 102 and slides along the axial direction of the cross bar 102 through the rollers 4,11. Since its diameter size is fixed, it can be stably fixed on the cross bar 102 after reaching the appropriate position. Subsequently, the operator rotates the control handle 402, and drives the stranded wire wheel 403 to rotate through the meshing transmission of the gear 405 and the transmission gear 413, thereby realizing the tightening of the guiding rope 420.

[0037] In one embodiment, the tensioning unit further includes a locking and fixing piece 407 and a tension spring 408. The locking and fixing piece 407 is fixedly connected to the ratchet locking piece 406. One end of the tension spring 408 is connected to the locking and fixing piece 407, and the other end is connected to the stranded wire housing 404. During the rotation of the stranded wire wheel 403, the elastic force of the tension spring 408 makes the locking and fixing piece 407 always tend to move closer to the lower end of the stranded wire housing 404, so that the ratchet locking piece 406 remains in contact with the transmission gear 413, thereby preventing the guiding rope 420 from rotating in the reverse direction and ensuring the tensioned state of the guiding rope 420. Therefore, the ratchet locking piece 406 restricts the bidirectional rotation of the transmission gear 413 and only allows the transmission gear 413 to rotate in one direction. Through the meshing of the gear 405 and the transmission gear 413, it is ensured that the stranded wire wheel 403 rotates in one direction to ensure that the guiding rope 420 is always in a tensioned state, thereby ensuring the smooth sliding of the hollow hook sleeve 201.

[0038] In one embodiment, a cushion block 304 is provided on the inner side of the hollow hook sleeve 201 close to the cross bar 102, and the cushion block 304 has a smooth surface. When the hollow hook sleeve 201 slides on the cross bar 102, the cushion block 304 plays a role in reducing friction, thereby reducing the frictional wear between the hollow hook sleeve 201 and the cross bar 102 and protecting the durability of the components.

[0039] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, 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, it should be considered as the scope recorded in this specification.

[0040] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
