Description

Technical Field

[0001] The invention relates to the technical field of angle steel tower installation, in particular to a whole-section assembled angle steel tower docking and positioning device. Background Art

[0002] Angle steel towers are also called power line towers, and power line towers are tower-shaped buildings used for power transmission. Their structural characteristics are that all types of towers are space truss structures, and the rods are mainly composed of single equilateral angle steel or combined angle steel. At present, when building power line towers, multiple rods are usually fixed and installed into multiple whole sections of assembled angle steel towers, and then various angle steel towers are transported to outdoor construction sites for on-site installation. When installing large power line towers, the base of the power line tower is usually fixed and installed on the foundation first, and then the multiple sections of assembled tower sections are lifted one by one by external lifting equipment to the installation location, and finally fixed and installed by manually operating bolt tools.

[0003] At present, strong winds are often encountered in on-site construction environments. For example, when installing on some high mountains, the strong wind will cause the entire angle steel tower hoisted to a high place to shake all the time or even rotate a certain angle around the hoisting position, resulting in misalignment between the hoisted tower section and the fixed tower section. Therefore, it is necessary to repeatedly adjust the angle of the hoisted tower section. This process is time-consuming and labor-intensive, and the installation efficiency is relatively low.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1-14 The embodiment of the present invention provides a whole-section assembled angle steel tower docking and positioning device, comprising a first docking beam 1 and a second docking beam 2, wherein a positioning column 3 is fixedly connected to the second docking beam 2; a first docking assembly 4 is arranged at the center between the first docking beam 1 and the second docking beam 2, wherein the first docking assembly 4 comprises a positioning sleeve 41 fixedly connected to the first docking beam 1, a sliding sleeve 42 vertically slidably connected in the positioning sleeve 41, and a docking sleeve 43 spirally connected in the sliding sleeve 42; a second docking assembly is respectively arranged at the four docking angles between the first docking beam 1 and the second docking beam 2, and each second docking assembly is arranged at the center between the first docking beam 1 and the second docking beam 2. The docking assembly includes an arc-shaped slot 5 arranged on the first docking beam 1 and an arc-shaped plug 15 arranged on the second docking beam 2; the process of the second docking beam 2 moving downward relative to the first docking beam 1 includes the following strokes in sequence: the first stroke drives the positioning column 3 to be inserted into the docking sleeve 43 and locked with the docking sleeve 43; the second stroke drives the positioning column 3 and the docking sleeve 43 to spirally descend relative to the sliding sleeve 42 to rotate the second docking beam 2, so that the arc-shaped plug 15 docks with the arc-shaped slot 5; the third stroke drives the positioning column 3, the docking sleeve 43 and the sliding sleeve 42 to descend, so that the arc-shaped plug 15 is inserted into the arc-shaped slot 5. Among them, a spiral groove 6 is opened on the inner wall of the sliding sleeve 42, and a sliding block 7 located in the spiral groove 6 is fixedly connected to the outer wall of the docking sleeve 43, wherein the number of turns of the spiral groove 6 is preferably one-sixth of a turn; as a preferred embodiment of the present invention, a protrusion is fixedly connected to the outer wall of the sliding sleeve 42, and a vertical sliding groove for vertical sliding of the protrusion is opened on the inner wall of the positioning sleeve 41, so that the sliding sleeve 42 can only move vertically linearly relative to the positioning sleeve 41; wherein a first compression spring is provided between the docking sleeve 43 and the sliding sleeve 42, which is sleeved on the inner wall of the docking sleeve 43, and one end of the first compression spring is fixedly connected to the inner wall of the bottom end of the sliding sleeve 42, and the other end is fixedly connected to the outer wall of the docking sleeve 43, and the process of the first compression spring restoring elastic deformation is used to drive the docking sleeve 43 to move upward relative to the sliding sleeve 42. It should be further explained that the first docking beam 1 is fixedly connected to the top of one of the angle steel tower sections, and the second docking beam 2 is fixedly connected to the bottom of the other angle steel tower section. The installation and docking process is to dock the bottom of the angle steel tower section corresponding to the second docking beam 2 to the top of the angle steel tower section corresponding to the first docking beam 1. When the lifting equipment lifts the angle steel tower section corresponding to the second docking beam 2 and drives the second docking beam 2 to be located above the first docking beam 1, the second docking beam 2 and the first docking beam 1 are connected as shown in FIG. Figure 2 As shown in FIG. 1 , it is a rotationally misaligned position relationship, and during the lifting process, the second docking beam 2 and the first docking beam 1 are rotated and misaligned in advance to the same position as shown in FIG. Figure 2The dislocation direction shown is so that the second docking beam 2 hoisted in the air can rotate and align in only one direction when docked with the first docking beam 1. Threaded holes are provided on both the first docking beam 1 and the second docking beam 2, and the threaded holes on the first docking beam 1 and the threaded holes on the second docking beam 2 are in a one-to-one correspondence, so that subsequent staff can insert fixing bolts into the corresponding threaded holes to fix the angle steel tower section of the first docking beam 1 with the angle steel tower section of the second docking beam 2. After the second beam frame that is rotationally dislocated with the first docking beam 1 is inserted into the docking sleeve 43, the cooperation between the docking sleeve 43 and the positioning column 3 can achieve a centering positioning installation effect, so that there will be no displacement deviation in the front, back, left, and right directions between the positioned and installed second docking beam 2 and the first docking beam 1.

[0032] Specifically, when the lifting equipment drives the second docking beam 2 to move downward relative to the first docking beam 1, the positioning column 3 will first be inserted into the docking sleeve 43, and the positioning column 3 and the docking sleeve 43 will be locked. At this point, the second docking beam 2 and the docking sleeve 43 are locked. After that, when the second docking beam 2 continues to move downward relative to the first docking beam 1, the positioning column 3 and the docking sleeve 43 fixedly connected to the second docking beam 2 are driven in a spiral descending manner to make the bottom of the second docking beam 2 relatively close to the top of the first docking beam 1. Finally, when the second docking beam 2 continues to move downward relative to the first docking beam 1, at this time, the positioning column 3 and the docking sleeve 43 fixedly connected to the second docking beam 2 The positioning column 3, the docking sleeve 43 and the sliding sleeve 42 will move downward synchronously, and in this process, the arc-shaped plug block 15 can not only be inserted into the arc-shaped slot 5 and move down a certain distance along the arc-shaped slot 5 until the bottom of the second docking beam 2 abuts against the top of the first docking beam 1; the above process can drive the second docking beam 2 to rotate to align with the first docking beam 1 during the process of moving downward relative to the first docking beam 1. At the same time, the process is simple to operate and there is no need to repeatedly adjust the position between the second docking beam 2 and the first docking beam 1, which is convenient for subsequent staff to fix the second docking beam 2 and the first docking beam 1 with fixing bolts, thereby improving the installation efficiency to a certain extent.

[0033] Among them, a first locking member 8 is provided in the docking sleeve 43, and the first locking member 8 includes a plurality of annularly distributed locking strips 81 and an elastic locking pin 82 arranged on the locking strips 81. Each locking strip 81 is radially slidably connected in the docking sleeve 43, and a plug-in cavity for inserting the docking block 10 of the positioning column 3 is formed between each locking strip 81. At least one clamping spring 83 is commonly sleeved on each locking strip 81, and the process of the clamping spring 83 restoring the elastic deformation drives each locking strip 81 to slide and close radially; at least one second locking member 9 is provided between the sliding sleeve 42 and the docking sleeve 43, and the second locking member 9 includes a first wedge block 91 radially slidably connected to the sliding sleeve 42, and a first locking rod 92 for locking the docking sleeve 43 is fixedly connected to the first wedge block 91, and a first spring 94 is provided on the sleeve of the locking rod, and a first spring 94 is provided on the docking sleeve 43. There is a first locking hole 93 for inserting the first locking rod 92; in the first stroke, when the positioning column 3 is driven to insert into the docking sleeve 43, the docking block 10 of the positioning column 3 abuts against each locking strip 81 to make the locking strip 81 slide radially apart, and the positioning column 3 abuts against the first wedge block 91 to make each first locking rod 92 disengage from the corresponding first locking hole 93, and then the positioning column 3 presses the docking sleeve 43 to drive the sliding block 7 to move downward along the spiral groove 6 to make the docking sleeve 43 rotate relative to the positioning column 3, until the elastic locking pin 82 is inserted into the insertion hole on the docking block 10 of the positioning column 3 to lock the positioning column 3 relative to the docking sleeve 43; in the second stroke, the positioning column 3 locked on the docking sleeve 43 presses the docking sleeve 43 to drive it to continue to move downward along the spiral groove 6 through the sliding block 7 to make the second docking beam 2 rotate to the arc plug block 15 to dock with the arc slot 5.In the preferred state, the positioning column 3 abuts against the inclined surface of the first wedge block 91 to make the protruding portion of the second locking member 9 unlocked need to be chamfered; wherein the locking strip 81 includes an L-shaped sliding rod radially slidably connected in the docking sleeve 43, and the upper end of the sliding rod is fixedly connected to an arc-shaped guide block, and the lower surface of the bottom of each arc-shaped guide block, the vertical section of the sliding rod and the horizontal section of the sliding rod form an insertion cavity that is snap-fitted with the docking block 10, wherein the lower surface of the bottom of each arc-shaped guide block abuts against the upper surface of the docking block 10 of the positioning column 3, and the lower surface of the docking block 10 of the positioning column 3 abuts against the horizontal section of the sliding rod. At this point, when the bottom of the positioning column 3 abuts against the inclined surface of the first wedge block 91, each locking strip 81 will slide radially along the docking sleeve 43 to move away from the center of the docking sleeve 43. When the docking block 10 is located in the insertion cavity, each The locking bar 81 slides together and locks the docking block 10 under the drive of the clamp spring 83, thereby limiting the upward and downward movement of the positioning column 3 fixedly connected to the second docking beam 2; it should be further explained that each elastic locking pin 82 includes a protruding block fixedly connected to the corresponding locking bar 81, a receiving cavity is provided in the protruding block, a locking head is radially slidably connected in the receiving cavity, and an ejection spring (not shown in the figure) for ejecting the locking head is provided in the receiving cavity, and the insertion end of the locking head includes a horizontal flat section and a chamfered arc edge, so that when the docking sleeve 43 is rotated relative to the positioning column 3 until the locking head is aligned with the socket on the docking block 10 provided on the positioning column 3, the relative rotation between the positioning column 3 fixedly connected to the second docking beam 2 and the docking sleeve 43 can be limited, and this process can make the positioning column 3 and the docking sleeve 43 relatively locked.

[0034] Among them, at least one third locking member 11 is provided between the positioning sleeve 41 and the sliding sleeve 42, and the third locking member 11 includes a locking portion radially slidably connected to the positioning sleeve 41 and a second elastic member 112 arranged between the locking portion and the positioning sleeve 41, and the locking portion includes a slope section 111 and a horizontal section 113, and the second elastic member 112 restores the elastic deformation stroke to drive the locking portion to slide radially so that the horizontal section 113 abuts against the bottom of the sliding sleeve 42. Among them, it should be noted that the second elastic member 112 includes a sliding rod and a second spring, and the sliding rod is radially slidably connected to the positioning sleeve 41, one end of the sliding rod is fixedly connected to the horizontal section 113 of the locking portion, and the second spring is sleeved on the sliding rod, and one end of the second spring is fixedly connected to the sliding rod, and the other end is fixedly connected to the positioning sleeve 41.

[0035] Among them, a trigger rod 12 is vertically slidably connected inside the positioning column 3, and a first elastic member 13 is provided between the trigger rod 12 and the positioning column 3. The trigger rod 12 is fixedly connected to each arc-shaped plug block 15 via a connecting rod 14; in the first stroke, each arc-shaped plug block 15 abuts against the first docking beam 1 to drive the trigger rod 12 to move vertically upward relative to the positioning column 3; in the second stroke, the positioning column 3 moves downward relative to the trigger rod 12 until the arc-shaped plug block 15 docks with the arc-shaped slot 5; in the third stroke, the first elastic member 13 restores the elastic deformation stroke to make the trigger rod 12 move downward, thereby forcing the trigger rod 12 to abut against the inclined surface section 111 to make the locking part slide radially until the horizontal section 113 is separated from the sliding sleeve 42. The first elastic member 13 can be an elastic telescopic rod, and one end of the elastic telescopic rod is fixedly connected to the trigger rod 12, and the other end is fixedly connected to the positioning column 3. When the elastic telescopic rod drives the trigger rod 12 to move down to the maximum stroke relative to the positioning column 3, the elastic telescopic rod is still in a compressed state, and the elastic force of the first elastic member 13 to restore the elastic deformation is preferably greater than the elastic force of the second elastic member 112 to restore the elastic deformation. At this point, the process of the first elastic member 13 restoring the elastic deformation can overcome the elastic force of the second elastic member 11 to restore the elastic deformation, thereby driving the trigger rod 12 to unlock the third locking member 11.

[0036] The bottom of the sliding sleeve 42 is in a frustum shape that is wider at the top and narrower at the bottom, and the sliding sleeve 42 has a slot for the trigger rod 12 to pass through. Among them, it should be noted that, when the third locking member 11 is in the locked state, the horizontal section 113 of the locking part abuts against the bottom of the sliding sleeve 42, and the inclined section 111 of the locking part is located below the slot, which is convenient for the subsequent trigger rod 12 to abut against the inclined section 111 of the locking part to make the locking part radially slide relative to the positioning sleeve 41 to complete the unlocking work, and when the third locking member 11 is in the unlocked state, the second spring on the second elastic member 112 is always in a compressed state, so the elastic force of the second spring restoring the elastic deformation will drive the inclined section 111 and the truncated cone surface at the bottom of the sliding sleeve 42 to be in abutment state, and when the third locking member 11 is switched from the unlocked state to the locked state, the elastic force of the second spring restoring the elastic deformation will drive the locking part to slide radially. The cooperation between the inclined section 111 and the truncated cone surface at the bottom of the sliding sleeve 42 can drive the sliding sleeve 42 to move upward relative to the positioning sleeve 41.

[0037] The specific installation process is as follows: when the second docking beam 2 in the state of rotational misalignment with the first docking beam 1 moves downward relative to the first docking beam 1, first, each arc-shaped plug-in block 15 will first abut against the first docking beam 1 to make the trigger rod 12 fixedly connected to each arc-shaped plug-in block 15 by the connecting rod 14 move vertically upward relative to the positioning column 3, and then the docking block 10 of the positioning column 3 will abut against each arc-shaped guide block to make each locking strip 81 slide radially and separate, when the positioning column 3 abuts against the first wedge block 91 to make the first locking rod 92 disengage from the first locking hole 93, at this time, the docking block 10 on the positioning column 3 is located in the insertion cavity, because the first locking rod 92 The first locking hole 93 has been disengaged, and the docking sleeve 43 and the sliding sleeve 42 are in a relatively unlocked state. Therefore, when the second docking beam 2 continues to move downward, the docking sleeve 43 will be pressed by the positioning column 3, and the sliding block 7 and the spiral groove 6 screw will cooperate to make the docking sleeve 43 rotate relative to the sliding sleeve 42 until the locking head of the elastic locking pin 82 is inserted into the socket on the docking block 10, thereby completing the locking between the positioning column 3 and the docking sleeve 43; thereafter, the positioning column 3 in the relatively locked docking sleeve 43 continues to press the docking sleeve 43 and the sliding block 7 and the spiral groove 6 screw are engaged. The second docking beam 2 rotates relative to the first docking beam 1 until the arc-shaped plug-in block 15 is aligned with the arc-shaped slot 5, and then the trigger rod 12 is driven to move downward relative to the positioning column 3 under the elastic force of the first elastic member 13 restoring the elastic deformation, and the arc-shaped plug-in block 15 fixedly connected to the trigger rod 12 by the connecting rod 14 slides vertically along the corresponding arc-shaped slot 5, and the arrangement between the arc-shaped slot 5 and the arc-shaped plug-in block 15 can reversely restrict the second docking beam 2 and the first docking beam 1 from continuing to move downward in a spiral through the sliding block 7 and the spiral groove 6, thereby completing the alignment work between the second docking beam 2 and the first docking beam 1; In the process of the trigger rod 12 moving downward relative to the positioning column 3, the bottom of the trigger rod 12 can press the inclined section 111 of the locking part to make the locking part slide radially relative to the positioning sleeve 41 until the horizontal section 113 of the locking part is separated from the bottom of the sliding sleeve 42. At this point, the positioning column 3, the docking sleeve 43 and the sliding sleeve 42 can move downward relative to the positioning sleeve 41 at the same time until the arc-shaped plug block 15 slides to the bottom end of the corresponding arc-shaped slot 5. At the same time, the bottom of the second docking beam 2 abuts against the top of the first docking beam 1, thereby completing the positioning and installation work between the second docking beam 2 and the first docking beam 1. In summary, the installation process can make the second docking beam 2, which is lifted directly above the first docking beam 1 and rotated and misaligned by the first docking beam 1, move downward relative to the first docking beam 1, driving the second docking beam 2 to rotate so as to be aligned with the first docking beam 1 and positioned for installation. At this point, there is no need to repeatedly adjust the position of the second docking beam 2 through the lifting equipment so that it is aligned up and down with the first docking beam 1, which reduces the time for positioning and installation between the second docking beam 2 and the first docking beam 1 to a certain extent, greatly improving the installation efficiency.

[0038] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
