Description

Technical Field

[0001] This invention relates to the field of power construction equipment technology, specifically a device for disassembling and assembling the standard section pin shaft of a ground-mounted pole. Background Technology

[0002] Ground-mounted gantry cranes, as a type of tower-building lifting equipment for ultra-high voltage transmission lines, have been widely used in the construction of power grid towers. Standard sections, as an important component of the metal structure of ground-mounted gantry cranes, are mainly connected by the cooperation of fishplates and pins. The disassembly and assembly of the pins often rely on manual hammering, which has the disadvantages of high labor intensity, high risk (working at heights), and high noise. It is also easy to cause deformation of the pins and fishplates, which brings inconvenience to maintenance.

[0003] During construction, the ground-mounted poles need to be moved frequently, and the pins need to be disassembled and assembled very frequently. Traditional manual disassembly and assembly methods can no longer meet the requirements for safe construction. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a device for disassembling and assembling standard section pins of a ground-mounted pole. This device replaces the traditional manual hammering method, reducing on-site labor intensity and improving the efficiency of pole pin disassembly and assembly.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A device for disassembling and assembling a standard section pin of a ground-mounted climbing pole, comprising a main frame fitted onto the outside of the climbing frame of the climbing pole;

[0007] The main frame includes a lifting crossbeam and a fixed frame body that is detachably and fixedly connected to the climbing frame. The fixed frame body includes a first fixed beam, and a second fixed beam extending to the same side is provided at both ends of the first fixed beam. The lifting crossbeam is slidably arranged between the two second fixed beams, and the clearance notch of the lifting crossbeam and the climbing frame is located on the same side.

[0008] A first driving component for driving the lifting beam to slide up and down is provided between the lifting beam and the fixed frame.

[0009] The main frame is equipped with a disassembly and assembly assembly for disassembling and assembling the pin.

[0010] The assembly and disassembly assembly includes an installation process shaft, a disassembly process shaft, and a second hydraulic cylinder fixedly mounted on the main frame. A shaft support is provided on the inner side of the main frame below the piston rod of the second hydraulic cylinder, and when the pin is placed on the shaft support, the pin is coaxial with the piston rod of the second hydraulic cylinder.

[0011] Both the installation process shaft and the disassembly process shaft are equipped with a connection structure at one end that cooperates with the piston rod of the second oil cylinder.

[0012] Furthermore, a positioning hole is provided at the other end of the installation process shaft, a support block is provided at the suspended end of the shaft support, and the support block is fixedly connected to the shaft support in a detachable manner. An arc-shaped groove is provided on the upper side of the support block, and the arc-shaped groove is coaxial with the positioning hole.

[0013] Furthermore, the other end of the installation process shaft is provided with a clearance slot that extends radially through the installation process shaft.

[0014] Furthermore, the shaft support is slidably connected to the main frame, and an elastic element is provided between the shaft support and the main frame to prevent the shaft support from approaching the main frame. Limiting posts are provided on both the installation process shaft and the disassembly process shaft. The shaft support is provided with a sliding groove that cooperates with the limiting post. When the second oil cylinder is in the retracted state, the limiting post abuts against the end of the sliding groove near the second oil cylinder, and the suspended end of the shaft support disengages from the column of the support rod.

[0015] Furthermore, a guide post is provided between the shaft support and the main frame. One end of the guide post is fixedly connected to the main frame by a threaded connection, and the other end of the guide post passes through a support plate fixedly installed on the shaft support. A spring is sleeved on the guide post between the main frame and the support plate.

[0016] Furthermore, the axle support is provided with two support plates.

[0017] Furthermore, the end of the guide post facing the main frame passes through the through hole of the second hydraulic cylinder connecting flange and is threadedly connected to the main frame. The guide post is provided with a fixing nut for tightening the connecting flange.

[0018] Furthermore, the guide post is provided with a flat opening.

[0019] Furthermore, guide plates are respectively provided on both sides of the lifting beam on the second fixed beam, and guide blocks are provided on the inner side of the guide plates. The guide blocks, guide plates and the second fixed beam together form a guide groove. End plates are respectively provided at both ends of the lifting beam, and the two ends of the end plates are respectively inserted into the guide groove and cooperate with the guide groove to achieve the guiding function.

[0021] The beneficial effects of this invention are:

[0022] This application provides a device for installing and removing standard section pins on a ground-mounted pole. The device is fixed to the pole's climbing frame and uses hydraulic components to push the pin, thus enabling the installation and removal of the pin. This device replaces the traditional manual hammering method, reducing labor intensity and noise pollution for on-site workers. It also protects the pin and the fishplate on the standard section, avoiding deformation caused by traditional hammering. Furthermore, compared to traditional manual hammering, this device reduces the number of personnel required for installing and removing the standard section connecting pins; only one person is needed, resulting in high efficiency, low workload, and convenient and quick pin installation or removal.

[0047] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0048] Example 1

[0049] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0050] like Figure 5 As shown, the mast includes a column 11 formed by sequentially connecting standard sections 112. A climbing frame 12 is fitted onto the lower end of the column 11. The climbing frame 12 includes a drive frame (not shown) and a base frame. The drive frame is located above the lower frame and is slidably connected to the base frame. A lifting cylinder for driving the drive frame to move up and down is provided between the drive frame and the base frame. A clearance notch 121 is provided at the lower end of the base frame to allow the standard sections 112 to enter and exit.

[0051] When installing the pole, the first standard section 112 is put into the climbing frame 12 through the avoiding gap 121, and the first standard section 112 is connected with the driving frame, and then the driving oil cylinder is actuated to lift up the driving frame and the first standard section 112. Then the second standard section 112 is put into the climbing frame 12, and the first standard section 112 and the second standard section 112 are connected as a whole through the pin shaft 111. Then the whole formed by the first standard section 112 and the second standard section 112 is connected with the driving frame, and is lifted up through the driving oil cylinder. The above operation is repeated to realize the installation of the pole. The dismounting process is the same, and is not described here.

[0052] As shown in Figure 1 , Figure 3 , Figure 6 and Figure 8 , a dismounting device for the pin shaft 111 of the standard section 112 of the floor pole comprises a main frame 21 which is sleeved outside the climbing frame 12, and the main frame 21 is fixedly connected with the bottom frame of the climbing frame 12 in a detachable manner.

[0053] The main frame 21 comprises a fixed frame body which is fixedly connected with the bottom frame of the climbing frame 12 in a detachable manner. The fixed frame body comprises a first fixed beam 211 which is located at the rear side of the climbing frame 12 and extends in the transverse direction, and the two ends of the first fixed beam 211 are respectively provided with a second fixed beam 212 which extends forwardly and perpendicularly to the first fixed beam 211, and the rear end of the second fixed beam 212 is fixedly connected with the first fixed beam 211, and the first fixed beam 211 and the second fixed beam 212 jointly form a U-shaped structure with the opening facing the front side, and the climbing frame 12 is located in the U-shaped structure.

[0054] As a specific embodiment, as shown in Figure 5 , the left and right sides of the bottom frame of the climbing frame 12 are respectively provided with two first mounting seats 122, as shown in Figure 6 , the front and rear ends of the lower side of the second fixed beam 212 are respectively provided with a second mounting seat 2121, and the first mounting seat 122 and the second mounting seat 2121 correspond to each other. The first mounting seat 122 is fixedly connected with the corresponding second mounting seat 2121 through a bolt assembly.

[0055] Further, the two second fixed beams 212 are respectively fixedly connected with the first fixed beam 211 in a detachable manner. As a specific embodiment, as shown in Figure 8As shown, the two ends of the first fixed beam 211 are respectively fixedly provided with first flange plates 2111 by welding. The rear end of the inner side (the side facing the climbing frame 12 is the inner side) of the second fixed beam 212 is fixedly provided with a second flange plate 2122 by welding. The second flange plate 2122 on the left side is fixedly connected with the first flange plate 2111 on the left side through a bolt assembly. The second flange plate 2122 on the right side is fixedly connected with the first flange plate 2111 on the right side through a bolt assembly.

[0056] The front side of the two second fixed beams 212 is provided with a lifting cross beam 213, and the lifting cross beam 213 and the avoiding gap 121 of the climbing frame 12 are located on the same side. The lifting cross beam 213 and the fixed frame body jointly form a square closed loop structure, and the climbing frame 12 is located in the closed loop structure. The two ends of the lifting cross beam 213 are respectively slidably connected with the fixed frame body. The lifting cross beam 213 can slide up and down relative to the fixed frame body. The lifting cross beam 213 and the fixed frame body are provided with a first driving component for driving the lifting cross beam 213 to slide up and down relative to the fixed frame body.

[0057] As a specific embodiment, the lifting cross beam 213 and the fixed frame body are provided with two first driving components, and the two first driving components are respectively located at the two ends of the lifting cross beam 213. In this way, the first driving component is located on both sides of the avoiding gap 121 of the climbing frame 12, thereby avoiding the avoiding gap 121 and avoiding interference between the standard section 112 and the first driving component when the standard section 112 enters or exits the climbing frame 12.

[0058] As shown, Figure 8 The front end of the second fixed beam 212 is provided with guide plates 2123 on the front and rear sides of the lifting cross beam 213. The guide plates 2123 are fixedly connected with the second fixed beam 212 by welding. The inner side (the side opposite to the two guide plates 2123 is the inner side) of the guide plate 2123 is provided with a guide block 2124 extending in the vertical direction. The guide block 2124, the guide plate 2123 and the second fixed beam 212 jointly form a guide groove with an opening facing the inner side (the side opposite to the two guide plates 2123 is the inner side). The two ends of the lifting cross beam 213 are respectively provided with end plates 2131. The front and rear ends of the end plate 2131 are respectively inserted into the guide groove and cooperated with the guide groove to realize the guiding effect. The end plate 2131 is fixedly connected with the lifting cross beam 213 by welding.

[0059] The front end of the second fixed beam 212 is fixedly provided with an mounting plate 2125 between the two guide plates 2123. The first driving component is a first hydraulic cylinder 22. The cylinder body of the first hydraulic cylinder 22 is fixedly provided with the lower side of the mounting plate 2125. The rod end of the piston rod of the first hydraulic cylinder 22 passes through the mounting plate 2125 and is fixedly connected to the lifting beam 213.

[0060] In one specific embodiment, the mounting plate 2125 is located below the guide plate 2123, and the front and rear ends of the mounting plate 2125 are fixedly connected to the lower end of the guide plate by welding. The end of the mounting plate 2125 facing the second fixed beam 212 is fixedly connected to the second fixed beam 212 by welding.

[0061] The main frame 21 is provided with a disassembly and assembly assembly 23 for disassembling and assembling the pins 111. The number of the disassembly and assembly assemblies 23 is the same as the number of pins 111 used to connect two adjacent standard sections 112, and their positions correspond one-to-one.

[0062] As one specific implementation method, such as Figure 3 and Figure 4 As shown, in this embodiment, two adjacent standard sections 112 are connected by eight pins 111, that is, the vertical beams of two adjacent standard sections 112 are connected by two mutually perpendicular pins 111. Correspondingly, as... Figure 6 and Figure 8 As shown, the first fixed beam 211, the second fixed beam 212 and the lifting beam 213 of the main frame 21 are each provided with a disassembly and assembly assembly 23.

[0063] like Figure 6 , Figure 7 and Figure 10 As shown, the disassembly and assembly assembly 23 includes a second hydraulic cylinder 231. The cylinder body of the second hydraulic cylinder 231 is detachably and fixedly connected to the main frame 21, and the piston rod of the second hydraulic cylinder 231 can extend into the interior of the main frame 21. A shaft support 232 is detachably and fixedly mounted on the main frame 21 below the piston rod of the second hydraulic cylinder 231. When the pin 111 is placed on the shaft support 232, the pin 111 is coaxial with the piston rod of the second hydraulic cylinder 231. For example, the shaft support 232 has a right-angled cross-section and is made of angle steel.

[0064] As a specific embodiment, the open end of the cylinder body of the second oil cylinder 231 is provided with a connecting flange 2311, and the connecting flange 2311 is fixedly connected to the inner side of the main frame 21 (the side close to the climbing frame 12 is the inner side). The blind end of the cylinder body of the second oil cylinder 231 extends through the main frame 21 to the outer side of the main frame 21, and the main frame 21 is provided with an avoiding hole for accommodating the cylinder body of the second oil cylinder 231. Taking the dismounting assembly 23 mounted on the lifting beam 213 as an example, the connecting flange 2311 is fixedly arranged on the inner side of the lifting beam 213 (the side close to the climbing frame 12 is the inner side), and the lifting beam 213 is provided with an avoiding hole for accommodating the cylinder body of the second oil cylinder 231, which penetrates the lifting beam 213 in the front-rear direction. The mounting structure of the dismounting assembly 23 arranged on the first fixed beam 211 and the second fixed beam 212 is the same, and will not be described here.

[0065] The dismounting assembly 23 further comprises a mounting process shaft 233 and a dismounting process shaft 234. The dismounting process shaft 234 is in the shape of a stepped shaft, comprising a first shaft segment and a second shaft segment, and the diameter of the first shaft segment is greater than that of the second shaft segment. One end of the mounting process shaft 233 and the end with larger diameter of the dismounting process shaft are both provided with a connecting structure matched with the piston rod of the second oil cylinder 231.

[0066] As a specific embodiment, as shown in Figure 13 and Figure 20 The connecting structure comprises a plug-in hole for accommodating the rod end of the piston rod of the second oil cylinder 231 and a clamping screw 235 for clamping the piston rod of the second oil cylinder 231, and the mounting process shaft 233 and the dismounting process shaft are both provided with a threaded hole matched with the clamping screw 235.

[0067] For ease of understanding, the insertion hole on the mounting process shaft 233 is defined as the first insertion hole 2331, and the threaded hole on the mounting process shaft 233 is defined as the first threaded hole 2332. The insertion hole on the disassembly process shaft 234 is defined as the second insertion hole 2341, and the threaded hole on the disassembly process shaft 234 is defined as the second threaded hole 2342. Specifically, one end face of the mounting process shaft 233 has a first insertion hole 2331 for accommodating the piston rod end of the second hydraulic cylinder 231, and the side wall of the first insertion hole 2331 has a first threaded hole 2332 that mates with the set screw 235. The end face of the disassembly process shaft 234, with its larger diameter, has a second insertion hole 2341 for accommodating the piston rod end of the second hydraulic cylinder 231, and the side wall of the second insertion hole 2341 has a second threaded hole 2342 that mates with the set screw 235.

[0068] Furthermore, in order to accommodate pins 111 of different diameters, such as Figure 10 and Figure 11 As shown, a positioning hole 2333 for accommodating the end of the pin 111 is provided on the end face of the other end of the mounting process shaft 233. A support block 236 is provided on the suspended end of the shaft support 232, and the support block 236 is fixedly connected to the shaft support 232 in a detachable manner. An arc-shaped groove that mates with the pin 111 is provided on the upper side of the support block 236, and the arc-shaped groove is coaxial with the positioning hole 2333.

[0069] In this way, when the diameter of the pin 111 changes, it is only necessary to replace the corresponding mounting process shaft 233 and support block 236 to ensure that the pin 111 is coaxial with the piston rod of the second oil cylinder 231 and coaxial with the pin hole on the rod.

[0070] In one specific embodiment, a screw 2361 is fixedly provided on the lower side of the support block 236 in this embodiment, and the lower end of the screw 2361 extends through the shaft support 232 to the lower part of the shaft support 232. A locking nut 2362 is provided on the screw 2361 below the shaft support 232, and under the locking action of the locking nut 2362, the support block 236 is pressed against the shaft support 232, thereby realizing the connection and fixation between the support block 236 and the shaft support 232.

[0071] Furthermore, since cotter pins need to be inserted into both ends of the pin 111 after it is inserted into the pin hole on the rod, for ease of operation, as follows: Figure 10 The other end of the installation process shaft 233 is provided with a relief groove 2334 that runs radially through the installation process shaft 233.

[0072] Further, the shaft support 232 is in sliding connection with the main frame 21, and the sliding direction of the shaft support 232 is parallel to the axis direction of the second oil cylinder 231. An elastic member is arranged between the shaft support 232 and the main frame 21 to prevent the shaft support 232 from approaching the main frame 21. Exemplarily, the elastic member is a spring 2382. Limiting posts 237 are arranged on the mounting process shaft 233 and the dismounting process shaft 234, and a sliding groove 2321 is arranged on the shaft support 232 to cooperate with the limiting posts 237. The end of the limiting post 237 extends into the sliding groove 2321. When the second oil cylinder 231 is in the retracted state, the limiting post 237 abuts against one end of the sliding groove 2321 close to the second oil cylinder 231, and under the limitation of the limiting post 237, the overhanging end of the shaft support 232 is separated from the column 11 of the guyed tower, and at this time, the spring 2382 is in the compressed state.

[0073] Further, the shaft support 232 and the main frame 21 are provided with at least two sets of guiding assemblies. As a specific embodiment, as shown in the drawings, in the embodiment, the shaft support 232 and the main frame 21 are provided with two sets of guiding assemblies, and the two sets of guiding assemblies are symmetrically arranged about the symmetry plane determined by the axis of the second oil cylinder 231. The guiding assembly comprises a guiding post 2381, one end of the guiding post 2381 is provided with external threads and is fixedly connected with the main frame 21 in a threaded connection manner, the other end of the guiding post 2381 extends to the inner side of the support plate (the side close to the column 11 is defined as the inner side) through the support plate fixedly arranged on the lower side of the shaft support 232, and the spring 2382 is sleeved on the guiding post 2381 between the main frame 21 and the support plate. Figure 7 Further, the shaft support 232 and the main frame 21 are provided with at least two sets of guiding assemblies. As a specific embodiment, as shown in the drawings, in the embodiment, the shaft support 232 and the main frame 21 are provided with two sets of guiding assemblies, and the two sets of guiding assemblies are symmetrically arranged about the symmetry plane determined by the axis of the second oil cylinder 231. The guiding assembly comprises a guiding post 2381, one end of the guiding post 2381 is provided with external threads and is fixedly connected with the main frame 21 in a threaded connection manner, the other end of the guiding post 2381 extends to the inner side of the support plate (the side close to the column 11 is defined as the inner side) through the support plate fixedly arranged on the lower side of the shaft support 232, and the spring 2382 is sleeved on the guiding post 2381 between the main frame 21 and the support plate.

[0074] Preferably, two support plates are arranged on the lower side of the shaft support 232. For the convenience of description, the support plates are defined as a first support plate 2322 and a second support plate 2323 in sequence along the extension direction of the shaft support 232, the spring 2382 is located between the main frame 21 and the first support plate 2322, and the other end of the guiding post 2381 extends to the inner side of the second support plate 2323 (the side close to the column 11 is defined as the inner side) through the first support plate 2322 and the second support plate 2323 in sequence.

[0075] Further, as shown in the drawings, Figure 12As shown, the end of the guide column 2381 towards the main frame 21 is screwed with the main frame 21 after passing through the through hole of the connecting flange 2311 of the second oil cylinder 231, and the fixed nut 2383 is arranged on the side of the guide column 2381 away from the main frame 21.

[0076] During installation, the fixed nut 2383 is tightly pressed on the connecting flange 2311 through the reverse back-up between the fixed nut 2383 and the main frame 21, so as to not only realize the fixed connection between the second oil cylinder 231 and the main frame 21, but also effectively prevent loosening. In this way, the guide column 2381 is not only a guide piece, but also a fixing piece for connecting the second oil cylinder 231 and the main frame 21, which is a dual-purpose piece, easy to install, and saves cost.

[0077] Further, in order to facilitate operation, the guide column 2381 is provided with a flat mouth 23811. Figure 12 As shown, the guide column 2381 is provided with a flat mouth 23811 near the outer thread.

[0078] Further, the overhanging end of the guide column 2381 is provided with a stop block 23812.

[0079] Illustratively, the guide column 2381 is made of a threaded bolt with a threaded end. During production, only a bolt with appropriate length is selected, and then the flat mouth 23811 is processed on the bolt rod.

[0080] Further, as shown in Figure 13 and Figure 20 The mounting process shaft 233 is provided with a first mounting hole 2335 for accommodating the limiting column 237, and the first mounting hole 2335 penetrates the mounting process shaft 233 in the radial direction. The dismounting process shaft 234 is provided with a second mounting hole 2343 for accommodating the limiting column 237, and the second mounting hole 2343 penetrates the dismounting process shaft 234 in the radial direction. As shown in Figure 15 The upper end of the limiting column 237 is fixedly provided with an arc-shaped clamping plate 2371, and the opening of the clamping plate 2371 corresponds to an angle less than 180°. Preferably, the inner diameter of the clamping plate 2371 is equal to the outer diameter of the larger one of the mounting process shaft 233 and the dismounting process shaft.

[0081] As shown in Figure 14As shown, when the limit post 237 needs to be installed, it only needs to be inserted into the first mounting hole 2335, and then the clamping plate 2371 is clamped to the outside of the installation process shaft 233. The process of disassembling the process shaft 234 to install the limit post 237 is the same, and will not be repeated here.

[0082] During the installation of the boom, the operation process of assembling the shaft is as follows:

[0083] First, install the installation process shaft 233 on the piston rod of the second oil cylinder 231 of each disassembly assembly.

[0084] Second, as shown, Figure 9 The first oil cylinder 22 acts to lift the lifting cross beam 213, thereby avoiding the avoidance gap 121 on the climbing frame 12, ensuring that the standard section 112 can smoothly pass through the avoidance gap 121 into the climbing frame 12, avoiding collision and interference with the main frame 21.

[0085] Third, place the standard section 112 into the climbing frame 12, and then actuate the first oil cylinder 22 to move the lifting cross beam 213 downward until the lifting cross beam 213 moves to the lower limit position. At this time, the disassembly assembly 23 located on the lifting cross beam 213 is aligned with the to-be-installed pin hole on the front side of the stand 11.

[0086] Fourth, as shown, Figure 2 Place the to-be-installed pin shaft 111 on the shaft support 232, with one end of the pin shaft 111 inserted into the positioning hole 2333 of the installation process shaft 233, and the other end supported by the support block 236.

[0087] Fifth, actuate the second oil cylinder 231 to push the pin shaft 111 to move closer to the stand 11. In this process, the shaft support 232 will also move closer to the stand 11 under the elastic action of the spring 2382, until as shown, Figure 16 and Figure 17 The overhanging end of the shaft support 232 abuts against the stand 11 of the boom.

[0088] Sixth, the second oil cylinder 231 continues to act, and since the overhanging end of the shaft support 232 has abutted against the stand 11 of the boom at this time, the shaft support 232 will not continue to extend under the action of the spring 2382, but will be in a fixed state. However, the pin shaft 111 will continue to move closer to the stand 11 of the boom under the action of the second oil cylinder 231, until as shown, Figure 18 The pin shaft 111 is inserted into the pin hole, and in this process, the limit post 237 slides in the sliding groove 2321.

[0089] Seventh, install the cotter pin.

[0090] Eighth, the second cylinder 231 piston rod retraction, the process is divided into two stages. First stage, the shaft bracket 232 does not move, the installation process shaft 233 is driven by the second cylinder 231 retraction, and the limit column 237 on the installation process shaft 233 moves away from the side of the embrace pole column 11 relative to the slide groove 2321, until the limit column 237 abuts on the end of the slide groove 2321 away from the embrace pole column 11. The second stage, the second cylinder 231 piston rod continues to retract, and under the drive of the limit column 237, pull the shaft bracket 232 together to move away from the embrace pole column 11 side, when the shaft bracket 232 will gradually away from the embrace pole column 11, to avoid interference with the shaft bracket 232 when lifting the column 11, the spring 2382 is compressed, until the second cylinder 231 piston rod is completely retracted.

[0091] Through the above process description can be known, by setting the shaft bracket 232 with the form of sliding, in the installation pin shaft 111, the shaft bracket 232 of the suspended end is in the state of abutting on the embrace pole column 11, which can effectively avoid the pin shaft 111 in the process of installation fall.

[0092] The process of disassembling the pin shaft 111 is similar to the installation process, as shown in Figure 19 , only need to replace the installation process shaft 233 into disassembly process shaft 234, hereinafter will not be repeated.
