Description

TECHNICAL FIELD

[0001] The present application relates to a clamping device, in particular to a heavy pole erecting and dismounting device. BACKGROUND

[0002] After the wooden poles are eliminated, most of the existing power poles are made of concrete materials, and in some cases where the strength requirement is high, even steel bars, steel cages and concrete materials are used. However, regardless of the material used, the erection and recovery of heavy power poles during the construction stage is a big problem.

[0003] In the traditional power pole erection stage, most of the power poles are lifted by cranes and hoists, and then placed in the designated position by manual guidance, and then fixed by earthwork and concrete. However, this fixing method requires the use of a crane, and in cities or some old urban areas, there is no place to install a crane, and the crane cannot enter, so it is difficult to move and place the pole. Therefore, how to move and erect the pole in a small space is a difficult problem in the industry.

[0004] In the existing structure, a walkable carrier is used, and a clamp capable of clamping the power pole is arranged on the carrier to clamp the power pole, so that the carrier can drive the power pole to move to the designated position and perform the pole erection action at the designated position. However, in this process, the clamp not only clamps the power pole, but also fixes and drives the power pole to move horizontally for a period of time. The power pole causes a large load on the entire clamp and the matching position of the clamp and the carrier. The stability of the clamping end is more tested during the turning and horizontal movement. Once the structural strength of the clamping end is not enough, the clamping end will be deformed or twisted during the clamping process.

[0005] Therefore, the present application aims to provide a heavy pole erecting and dismounting device capable of bidirectionally strengthening the clamping end of the power pole and the strength of the position between the clamping end and the carrier, so as to stably support the power pole during the translation and turning of the clamp clamping the power pole, avoid damaging the power pole, and ensure the stability of the clamp. SUMMARY

[0006] The present application provides a heavy pole erecting and dismounting device, which can effectively solve the above problems.

[0007] The present application is implemented as follows:

[0008] A heavy pole erecting and dismounting device, comprising:

[0009] An installation structure, comprising a mounting plate fixed on a carrier, a receiving cylinder welded in the middle of the front surface of the mounting plate, corner plates fixed on both sides of the mounting plate, and a locking member located at the opening of the back surface of the mounting plate;

[0010] A clamping structure, comprising a linkage member inserted into the receiving cylinder, a bottom support frame welded at the end of the linkage member away from the receiving cylinder, two upper clamping members hinged on the bottom support frame, a clamping cylinder hinged at one end on the upper clamping member and at the other end on the bottom support frame, and the end of the linkage member inserted into the receiving cylinder is threadedly connected with the locking member, and the locking member is tightly attached to the back surface of the mounting plate after being rotated;

[0011] The bottom support frame has a support frame welded on the outer wall of the linkage member, side mounting frames located on both sides of the support frame and used for mounting the upper clamping members and the clamping cylinder, a first supporting plate located inside the two side mounting frames, and two groups of lower clamping members fixed on the first supporting plate, wherein the two lower clamping members correspond to the two upper clamping members.

[0012] A reversing structure, comprising a reversing cylinder hinged on the corner plate, ear plates fixed on the output end of the reversing cylinder, and rotating plates hinged on the two ear plates, wherein the rotating plates are sleeved and clamped on the outer side of the linkage member.

[0013] As a further improvement, the bottom support frame further comprises a support rod embedded between the two side mounting frames, wherein the support rod is attached to the bottom of the support frame and presses on the bottom of the linkage member.

[0014] As a further improvement, the support frame comprises a first connecting plate welded between the two side mounting frames, a second connecting plate downwardly connected to one side of the first supporting plate, wherein the second connecting plate is welded on the top of the support rod, a wedge-shaped opening is formed in the middle of the second connecting plate, the linkage member penetrates through the wedge-shaped opening and is welded on the support rod.

[0015] As a further improvement, the linkage member has a threaded portion threadedly matched with the locking member, a clamping portion connected with the threaded portion and clamped with the rotating plate, an inner matching shaft connected with the clamping portion, an outer matching shaft sleeved on the outer part of the inner matching shaft and welded with the second connecting plate and the support rod, and a locking pin penetrating through the inner matching shaft and the outer matching shaft.

[0016] As a further improvement, the rotating plate has two first and second arc-shaped plates with opposite extension directions, a flat hole matched with the clamping portion, and a flat position on the outer side of the clamping portion corresponding to the inner recess of the flat hole, wherein the first and second arc-shaped plates are respectively hinged with the two ear plates.

[0017] As a further improvement, the side mounting frame comprises a side mounting seat connected with the first connecting plate and the second connecting plate, a first hinging seat and a second hinging seat arranged in the side mounting seat and connected with the upper clamping member, and a lower supporting plate arranged from the side mounting seat and extending away from the mounting plate, the lower supporting plate being arranged above the lower clamping member.

[0018] As a further improvement, the upper clamping member comprises a swing seat hinged with the clamping cylinder through a shaft sleeve, two swing plates of the swing seat being hinged on both sides of the second hinging seat, and a second supporting plate being locked at the bottom of the second hinging seat.

[0019] As a further improvement, the second supporting plate comprises a U-shaped seat connected with the swing seat, a plurality of clamping blocks locked in the U-shaped seat, and a counterweight shaft welded on one side of the U-shaped seat and fixedly welded with an end extension of the swing seat, the lower clamping member being identical in structure with the clamping blocks and the counterweight shaft.

[0020] As a further improvement, the clamping blocks are rubber pads, and the surface of the rubber pads is provided with a plurality of friction lines.

[0021] As a further improvement, a plurality of metal meshes are inserted into the interior of the clamping blocks, and the metal meshes in the upper clamping blocks and the lower clamping blocks are staggered.

[0022] The present application has the following advantages:

[0023] When the clamped power pole is moved to a position where the power pole is to be erected, the power pole also needs to be horizontally moved by a distance, and the pressure bearing capacity of the clamping position is required to be higher. The present application arranges two groups of lower clamping members on the same first supporting plate, and arranges two groups of upper clamping members above the same first supporting plate. The two clamping points are ensured, and the two pressure bearing points at the bottom are concentrated on the same plate. The pressure bearing and force unloading of the same plate can improve the stress load of the whole device. Even if two power poles are clamped at the same time, the device can be stably supported. Therefore, the horizontal single-point pressure bearing and the longitudinal double-point clamping are ensured, and the transportation and erection of the power pole are promoted.

[0024] After the weight of the power pole is entirely borne by the first supporting plate, although the surface support is more effective than the single-point support, the force is indirectly concentrated on the bottom support frame, and the whole bottom support frame suffers from great stress. Therefore, the present application further welds a linkage member to the bottom support frame, and extends the linkage member to the mounting plate. Since the mounting plate is directly fixed on the carrier, the pressure of the whole bottom support frame is dispersed to the carrier, and the carrier bears the pressure of a single power pole or double power poles. Therefore, in the case of surface stress, the concentrated stress damage to the bottom support frame can be avoided.

[0025] Although the bottom support frame can guide the force to the carrier through the linkage, if the position of the bottom support frame in contact with the linkage is weak, the bottom support frame will directly deform, resulting in shaking during clamping or overturning of the vertical pole, so the present application sets a support rod on the inner side of the linkage, which can first connect and fix the support frame in the bottom support frame through the support rod, improve the strength of the support frame, and then weld the end of the linkage to the support rod, improve the contact area of the bottom support frame and the linkage, and the force transmission area is larger when unloading, thereby better sharing the pressure on the bottom support frame, making the contact position of the bottom support frame and the linkage less likely to deform.

[0026] Since the support frame needs to give way to the linkage and the upper clamping piece, but at the same time the support frame itself needs to maintain a certain strength, the support frame is divided into a first connecting plate and a second connecting plate in the present application, the second connecting plate is inclined to avoid the upward turning action of the upper clamping piece, and a wedge-shaped opening is formed on the second connecting plate to give way to the linkage, thereby ensuring maximum strength while not hindering the action of other structures.

[0027] The linkage in the present application has the effect of linkage with multiple structures, one is that the threaded part cooperates with the locking piece, since the locking piece is fixed and tightly attached to the back of the mounting plate, the threaded part extending to the mounting plate position can be tightened, even if the linkage turns or is stressed, the clamping structure and the mounting structure will not separate, ensuring the stability of the clamping structure while being the main transmission path for unloading, the second is that the clamping part cooperates with the reversing structure, the clamping part rotates during the rotation of the reversing structure, causing the entire clamping structure to rotate, thereby changing the instrument from a clamped moving state to a vertical pole state, and the third is that the outer cooperating shaft cooperates with the support frame, since the threaded part, the clamping part and the inner cooperating shaft are turned into a shape by one shaft, but if only the inner cooperating shaft cooperates with the support frame, the pipe diameter of the inner cooperating shaft is not enough, therefore, in order to increase the contact area, the outer cooperating shaft is sleeved on the inner cooperating shaft, and then fixed by the locking pin, thereby increasing the contact area without affecting the integrated setting of the entire linkage.

[0028] After the function of the clamping structure is realized, the telegraph pole can be smoothly transported to the installation position, and after reaching the specified position, the telegraph pole needs to be inserted into the hole that has been drilled, at which time the entire instrument needs to be turned over, since the above-mentioned unloading force transmission method is adopted for the linkage, only the linkage needs to be turned over during turning, in the present application, the rotating piece is sleeved on the linkage, and the rotating piece will directly rotate with the extension and retraction of the reversing cylinder, thereby driving the linkage and the clamping structure to rotate, and further causing the telegraph pole on the clamping structure to be turned over to a vertical state, the reversing cylinder directly drives the clamping part to rotate without contacting other structures, reducing the cooperating structure, thereby improving the adjustment accuracy.

[0029] If the clamping part is only a simple pipe structure, and the rotating piece is only a simple circular opening, they will be in a slipping state all the time, so in order to ensure the rotating effect, the application sets a flat position in the clamping part, and sets the hole position of the rotating piece as a flat hole, so that they can form a fixed effect after cooperation, and once the rotating piece rotates, the corresponding linkage of the clamping part will also rotate.

[0030] In the whole clamping process, the second supporting plate is flipped while the first supporting plate is stationary, and the position in contact with the telegraph pole cannot be rigidly set, otherwise it is easy to cause damage to the telegraph pole, so the application sets the clamping block as a rubber pad, which directly contacts the telegraph pole and is not easy to break during clamping.

[0031] However, during the actual use stage, when the telegraph pole is flipped from horizontal to vertical, the stress of one side of the clamping block will suddenly increase, and the sudden pressure will damage the rubber structure inside the clamping block, causing the fixed telegraph pole to start to shake. To this end, the application embeds a metal mesh in the inside of the clamping block, which improves the instantaneous pressure bearing capacity of the clamping block through the added metal mesh.

[0032] In fact, the reversing cylinder can change the rotating direction of the rotating piece by retracting or pushing out, but it is difficult to determine which direction the supporting plate will bear the sudden pressure, and at the same time, both supporting plates may also bear the sudden pressure at the same time. To this end, the metal meshes in the end clamping block and the lower end clamping block are arranged in a staggered manner, so that the reinforced points of the two ends are arranged in a staggered manner, forming a ring-shaped reinforcing surface arranged in a staggered manner and opposite to each other, which is more stable when fixing the circular telegraph pole.

In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0047] Referring to Figures 1-11 As shown in the drawings, a heavy vertical pole loading and unloading device comprises a mounting structure 10, the mounting structure 10 comprising a mounting plate 11 locked on a carrier, a containing cylinder 12 welded in the middle of the front face of the mounting plate 11, corner plates 13 locked on both sides of the mounting plate 11, and locking members 14 located at the openings in the back of the mounting plate 11; a clamping structure 20, the clamping structure 20 comprising a linkage 21 inserted into the containing cylinder 12, a bottom support frame 22 welded on the end of the linkage 21 away from the containing cylinder 12, two upper clamping members 23 hinged on the bottom support frame 22, a clamping cylinder 24 hinged on one end of the upper clamping member 23 and on the other end of the bottom support frame 22, the end of the linkage 21 inserted into the containing cylinder 12 being threadedly connected with the locking members 14, and the locking members 14 being turned to fit on the back of the mounting plate 11; the bottom support frame 22 having a middle opening and a support frame 221 welded on the outer wall of the linkage 21, side mounting frames 222 located on both sides of the support frame 221 and used for mounting the upper clamping members 23 and the clamping cylinder 24, first supporting plates 223 located inside the side mounting frames 222, two groups of lower clamping members 224 locked on the first supporting plates 223, and the two groups of lower clamping members 224 corresponding to the two upper clamping members 23; a reversing structure 30, the reversing structure 30 comprising a reversing cylinder 31 hinged on the corner plate 13, ear plates 32 locked on the output end of the reversing cylinder 31, and rotating plates 33 hinged on the two ear plates 32, the rotating plates 33 being sleeved and clamped on the outside of the linkage 21.

[0048] In the embodiment, the carrier is a foldable cantilever beam vehicle, which only needs to have a foldable mechanical hand, and the mounting plate 11 is locked on the end of the mechanical hand, so that the loading and unloading device is fixed, and the rotation of the loading and unloading device is realized by itself without relying on the rotation of the carrier.

[0049] In the whole process of installing the electric pole, it is divided into two steps, horizontal clamping and vertical pole erection, first of all, the electric pole needs to be moved to the designated area through horizontal clamping, and then the pole is rotated, when the clamped electric pole is moved to the position of the erected pole, the electric pole needs to be horizontally moved for a distance, so the pressure bearing capacity of the clamping position is required to be higher, sometimes it is not only a single electric pole, but also two electric poles, for this, the two groups of lower clamping pieces 224 are arranged on the same first supporting plate 223, and two groups of upper clamping pieces 23 are arranged above the same first supporting plate 223, while ensuring two clamping points, the two pressure points at the bottom are concentrated on the same plate, and the load bearing of the whole device is improved through the pressure bearing and unloading of the same plate, even if two electric poles are clamped at the same time, they can be stably supported, so that the horizontal single-point pressure bearing and the longitudinal double-point clamping can be guaranteed, and the transportation and pole erection process are both promoted.

[0050] After the weight of the electric pole is entirely borne by the first supporting plate 223, although the surface support is more effective than the single-point support, the force is indirectly concentrated on the position of the bottom support frame 22, so that the whole bottom support frame 22 suffers from great stress, therefore, the linkage 21 is further welded to the bottom support frame 22, and the linkage 21 is extended to the mounting plate 11, since the mounting plate 11 is directly fixed on the carrier, the pressure borne by the whole bottom support frame 22 is dispersed to the carrier, so that the carrier bears the pressure of a single or double electric pole, thereby avoiding concentrated stress damage to the bottom support frame 22 in the case of surface stress.

[0051] Although the bottom support frame 22 can guide the force to the carrier through the linkage 21, if the position where the bottom support frame 22 contacts the linkage 21 is weak, the bottom support frame 22 will directly deform, resulting in shaking in the process of clamping or overturning the pole, so the contact between the bottom support frame 22 and the linkage 21 needs to be improved, therefore, the bottom support frame 22 in the embodiment further comprises a supporting rod 225 embedded between the two side mounting frames 222, the supporting rod 225 is attached to the bottom of the supporting frame 221 and presses the bottom of the linkage 21, the supporting rod 225 is arranged on the inner side of the linkage 21, first of all, the supporting rod 225 can be used to connect and fix the supporting frame 221 in the bottom support frame 22, so as to improve the strength of the supporting frame 221, then, the end of the linkage 21 is welded to the supporting rod 225, so as to improve the contact area between the bottom support frame 22 and the linkage 21, the transmission area is larger when unloading, so that the pressure borne by the bottom support frame 22 is better shared, and the contact position between the bottom support frame 22 and the linkage 21 is less likely to deform.

[0052] Since the support frame 221 needs to give way to the linkage 21 and the upper clamping piece 23, but at the same time the support frame 221 itself needs to maintain a certain strength, therefore the support frame 221 comprises a first connecting plate 2211 welded between two side mounting frames 222, the first connecting plate 2211 is connected downward to one side of the first supporting plate 223 with a second connecting plate 2212, the second connecting plate 2212 is welded on the top of the supporting rod 225, the middle part of the second connecting plate 2212 is provided with a wedge-shaped opening 2213, the linkage 21 penetrates through the wedge-shaped opening 2213 and is welded on the supporting rod 225, the support frame 221 is divided into the first connecting plate 2211 and the second connecting plate 2212, the second connecting plate 2212 is arranged obliquely to avoid the upward turning action of the upper clamping piece 23, and at the same time the wedge-shaped opening 2213 is provided on the second connecting plate 2212 to give way to the linkage 21, thereby ensuring the maximum strength while not hindering the action of other structures.

[0053] As can be seen from the above, the linkage 21 plays a great role and has the effect of linkage with multiple structures, which is specifically provided as follows: the linkage 21 has a threaded part 211 threadedly matched with the locking piece 14, a clamping part 212 connected to the threaded part 211 and clamped and fixed with the rotating piece 33, an inner matching shaft 213 connected with the clamping part 212, an outer matching shaft 214 sleeved outside the inner matching shaft 213 and welded with the second connecting plate 2212 and the supporting rod 225, and a locking pin 215 penetrating through the inner matching shaft 213 and the outer matching shaft 214, which has three functions: first, the threaded part 211 is matched with the locking piece 14, since the locking piece 14 is fixed and tightly attached to the back of the mounting plate 11, the threaded part 211 extending to the position of the mounting plate 11 can be fastened, even if the linkage 21 turns or is stressed, the clamping structure 20 will not be separated from the mounting structure 10, which ensures the stability of the clamping structure 20 while being the main transmission path of unloading;

[0054] Second, the clamping part 212 is matched with the reversing structure 30, during the rotation of the reversing structure 30, the clamping part 212 is rotated to drive the whole clamping structure 20 to rotate, so that the instrument changes from the clamped and moved state to the vertical rod state;

[0055] Third, the outer matching shaft 214 is welded with the support frame 221, since the threaded part 211, the clamping part 212 and the inner matching shaft 213 are formed by turning a shaft, but if only the inner matching shaft 213 is matched with the support frame 221, the pipe diameter of the inner matching shaft 213 is not enough, therefore in order to increase the contact area, the outer matching shaft 214 is sleeved on the inner matching shaft 213 and is fixed by the locking pin 215, so that the contact area is increased while the integrated setting of the whole linkage 21 is not affected;

[0056] Through the structure design of the threaded part 211, the clamping part 212, the inner fitting shaft 213 and the outer fitting shaft 214, the head and tail of the whole linkage 21 are in series with other structures, and since the linkage 21 is basically an entire shaft, it is not easy to break when coping with stress transmission, and the torsional strength is stronger.

[0057] In order to avoid the direct friction between the threaded part 211 and the mounting plate 11, which causes the threaded part 211 to be worn, a bearing is embedded at the position of the threaded part 211 corresponding to the mounting plate 11. Through the bearing, the threaded part 211 can not only avoid being directly affected by the mounting plate 11, but also ensure the rotation accuracy of the whole linkage 21.

[0058] After the function of the clamping structure 20 is realized, the telegraph pole can be smoothly transported to the installation position. After reaching the specified position, the telegraph pole needs to be erected and inserted into the hole that has been drilled. At this time, the whole device needs to be turned over. Since the above-mentioned force transmission mode of the linkage 21 is adopted, only the linkage 21 needs to be turned over when turning over. In this embodiment, the rotating piece 33 is sleeved on the linkage 21, and the extension of the reversing cylinder 31 directly drives the rotating piece 33 to rotate, thereby driving the linkage 21 and the clamping structure 20 to rotate, and further making the telegraph pole on the clamping structure 20 be turned over to a vertical state. The reversing cylinder 31 directly drives the clamping part 212 to rotate, without the need to contact other structures, thereby reducing the matching structure and improving the adjustment accuracy.

[0059] If the clamping part 212 is only a simple circular tube structure and the rotating piece 33 is only a simple circular opening, the two will always be in a slipping state. Therefore, in order to ensure the effect of rotation, the rotating piece 33 has two first arc-shaped pieces 331 and second arc-shaped pieces 332 with opposite extension directions, a flat hole 333 matched with the clamping part 212, and a flat position 2121 on the outer side of the clamping part 212 corresponding to the inner recess of the flat hole 333. The first arc-shaped pieces 331 and the second arc-shaped pieces 332 are respectively hinged to the two ear plates 32. The present application sets the flat position 2121 in the clamping part 212, and sets the hole position of the rotating piece 33 as the flat hole 333. After the cooperation of the two, a fixed effect can be formed. Once the rotating piece 33 rotates, the corresponding linkage 21 of the clamping part 212 will also rotate.

[0060] The strength of the mounting structure is required at the outer side of the first connecting plate 2211 and the second connecting plate 2212 and the mounting position of the upper clamping part 23 and the lower clamping part 224, and the structure is fixed in the same area by the side mounting frame 222 in the embodiment, specifically: the side mounting frame 222 includes a side mounting seat 2221 connected with the first connecting plate 2211 and the second connecting plate 2212, a first hinge seat 2222 and a second hinge seat 2223 arranged in the side mounting seat 2221 and connected with the upper clamping part 23, a lower supporting plate 2224 extending from the side mounting seat 2221 away from the mounting plate 11 side, and the lower supporting plate 2224 supports above the lower clamping part 224, so whether the first connecting plate 2211 and the second connecting plate 2212 are in the process of limiting linkage 21 or the upper clamping part 23 and the lower clamping part 224 are in the process of clamping the pole, the side mounting frame 222 can be strongly supported.

[0061] The upper clamping part 23 responsible for clamping and fixing is directly mounted on the upper clamping part 23, specifically, the upper clamping part 23 includes a swing seat 233 hinged with the clamping cylinder 24 through a shaft sleeve 232, two swing plates of the swing seat 233 are hinged on both sides of the second hinge seat 2223, a second supporting plate 234 is locked at the bottom of the second hinge seat 2223, and the two supporting plates are used for clamping the pole.

[0062] The lower clamping part 224 and the clamping block 2342 and the counterweight shaft 2343 are arranged at different positions, but the structures of the two are the same, and the second supporting plate 234 is unfolded in the embodiment, which is equivalent to directly disclosing the structure of the lower clamping part 224, specifically, the second supporting plate 234 includes a U-shaped seat 2341 connected with the swing seat 233, a plurality of clamping blocks 2342 locked in the U-shaped seat 2341, a counterweight shaft 2343 welded on one side of the U-shaped seat 2341 and fixedly welded with the end extension of the swing seat 233, in the clamping process, the U-shaped seat 2341 can accommodate at most two poles, if two poles are accommodated, the poles are respectively located in the two side plates of the U-shaped seat 2341, and if only one pole is accommodated, the pole is pushed to the inside of the U-shaped seat 2341 and fixed inside as the push rod cylinder 231 pushes downward, and the design of the counterweight shaft 2343 on the outside is also to make the weight on the outside larger in the single clamping action.

[0063] The position in contact with the electric pole cannot be rigidly arranged, otherwise the electric pole is easily damaged during the whole clamping process of the first supporting plate 223 not moving and the second supporting plate 234 turning over, the clamping block 2342 is a rubber pad, directly in contact with the electric pole, not easy to break during clamping, and in order to improve the friction of clamping, the surface of the rubber pad has a plurality of friction lines 23421.

[0064] But in the actual use stage, when the electric pole is turned from horizontal to vertical, the stress of one side clamping block 2342 will suddenly increase, the sudden pressure will damage the rubber structure inside the clamping block 2342, so that the fixed electric pole begins to shake, for this, the metal mesh 23422 is embedded in the clamping block 2342, the instantaneous pressure bearing capacity of the clamping block 2342 is improved by the added metal mesh 23422.

[0065] In fact, the reversing cylinder 31 can change the rotating direction of the rotating piece 33 by retracting or pushing out, then it is difficult to judge which direction of the supporting plate bears the sudden increase of pressure, at the same time, two supporting plates may also bear the sudden change of pressure at the same time, for this, the metal mesh 23422 in the end clamping block 2342 and the lower end clamping block 2342 are arranged staggered, the reinforced points of the two ends are staggered, an annular reinforced surface is formed by the staggered arrangement, which is arranged in a spaced and opposite manner, and is more stable when fixing the circular electric pole.

[0066] The above only describes the preferred embodiments of the present application and is not used to limit the present application, for those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
