Description

Technical Field

[0001] This disclosure relates to the field of wrist arm mounting technology, and more particularly to a wrist arm turnover device. Background Technology

[0002] The cantilever arm is an important supporting device for the overhead contact system of high-speed railways. It is fixed to the support column by insulators to secure the positioning device. The cantilever arm has a triangular structure, which includes insulators, cantilever tubes, and cantilever supports.

[0003] Traditional cantilever arm installation typically involves manually pulling ropes to hoist the individual cantilever arm components to a height, then workers climb to the anchor points on the support pillars to assemble the components. From a construction perspective, this method is cumbersome, requires numerous tools and personnel, is time-consuming, and lacks standardization. To address this, an automated cantilever arm installation device has been developed. This device allows for the pre-assembly of the cantilever arm into assemblies on the construction site, followed by on-site installation using a robotic arm. This significantly reduces installation time and accelerates the construction progress of the overhead contact system. However, because both pre-assembly and installation are completed on-site, the installation equipment requires numerous on-site steps, has a complex control system, necessitates a large number of on-site personnel, and presents significant operational challenges and safety hazards. Conversely, pre-assembling the cantilever arm components in the factory presents transportation difficulties. The cantilever arm assembly is prone to deformation during transportation due to vibration and other reasons. Once deformation occurs, it can easily become a safety hazard during subsequent use. Under the long-term vibration, temperature changes and other operating conditions of high-speed railways, the cantilever arm may bend further or even break, causing accidents with unimaginable consequences. Summary of the Invention

[0004] To address the aforementioned technical problems, this disclosure provides a wrist-arm rotation device.

[0005] This disclosure provides a wrist-arm rotation device, comprising:

[0006] Support frame;

[0007] Multiple transfer templates are used to install and fix the cantilever arm and form a cantilever arm assembly with the cantilever arm. When the cantilever arm is installed on the transfer template, the cantilever arm tube of the cantilever arm extends horizontally out of the transfer template. Multiple cantilever arm assemblies can be stacked on the support frame, and adjacent transfer templates can be plugged into each other.

[0008] The sleeper is vertically mounted on the support frame and can rotate horizontally relative to the support frame. Multiple support grooves are provided on both sides of the sleeper along the height direction. Rotating the sleeper allows the carpal tube of the carpal arm to be horizontally inserted into the support groove at the corresponding height, so that the carpal tube of the carpal arm is supported by the sleeper.

[0009] Optionally, the cantilever arm includes a flat cantilever arm and an inclined cantilever arm. Both the flat cantilever arm and the inclined cantilever arm include an insulator and a cantilever tube connected to the insulator. The insulator is fixed on the transfer template, and the cantilever tube extends horizontally out of the transfer template. The cantilever tubes of the flat cantilever arm and the inclined cantilever arm are gradually moved closer together along the direction of extending out of the transfer template.

[0010] The sleeper is located in the space between the carpal tube of the flat carpal arm and the carpal tube of the oblique carpal arm. The carpal tube of the flat carpal arm and the carpal tube of the oblique carpal arm are respectively supported in the support grooves located on both sides of the sleeper.

[0011] Optionally, the support frame includes a base frame and two base frames. The two base frames are located at both ends of the base frame along the length direction, and the two base frames have different heights so that multiple cantilever assemblies can be divided into two groups and placed on the two base frames respectively, and the two groups of cantilever assemblies are arranged alternately and staggered along the height direction.

[0012] Optionally, there are two sleepers, which are arranged sequentially on the base frame along the width direction to support the cantilever tubes of the cantilever assembly placed on the two base frames.

[0013] Optionally, the support grooves on the two sleepers are arranged one-to-one along the height direction of the sleepers. The arm tubes of the multiple arm assemblies arranged sequentially along the height direction in each group are respectively supported on the support grooves spaced apart along the height direction, and the arm tubes of the two groups of arm assemblies are respectively supported on the support grooves at different height positions.

[0014] Optionally, the sleeper and the base frame are connected by a rotating component, the lower end of which is embedded in the base frame, and the upper end of which is detachably connected to the sleeper.

[0015] Multiple bolts are detachably inserted between the sleeper and the base frame, with the bolts respectively located on both sides of the rotating component.

[0016] Optionally, the base frame is provided with multiple first through holes, and the transfer template is provided with multiple second through holes. The first through holes and the second through holes correspond one to one, and bolts are inserted into the first through holes and the second through holes to connect the base frame and the transfer template.

[0017] And / or, locking elements are provided on both sides of the base frame, which are used to lock the base frame to the transport vehicle;

[0018] And / or, the base frame is equipped with multiple lifting components to enable the lifting of the cantilever rotation device.

[0019] Optionally, the transfer template includes a mounting base and a wrist arm clamping device disposed on the mounting base, the wrist arm clamping device being used to clamp the wrist arm;

[0020] The mounting base has multiple vertically arranged plug-in parts around its perimeter. The plug-in parts protrude vertically from the upper surface of the mounting base at a predetermined height. The upper end of the plug-in part forms a first plug-in part, and the lower end of the plug-in part extends downward to the bottom of the mounting base, forming a second plug-in part. The first plug-in part of one transfer template is adapted to be plugged into and cooperate with the second plug-in part of another transfer template.

[0021] Optionally, the wrist arm clamping device is provided in two sets. The two sets of wrist arm clamping devices are used to clamp the wrist arm tube of the flat wrist arm and the wrist arm tube of the inclined wrist arm, respectively. The two sets of wrist arm clamping devices are rotatably connected to the mounting base through the connecting shaft, so that the wrist arm clamping device can rotate on the mounting base around the connecting shaft.

[0022] The mounting base has mounting holes for mounting the connecting shaft. One of the mounting holes is an elongated hole, so that the mounting position of the connecting shaft in the elongated hole is adjustable.

[0023] Optionally, the bottom of each of the two wrist arm gripping devices is provided with rollers so that the rollers can roll on the mounting base when the wrist arm gripping device rotates around the connecting shaft.

[0024] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0025] The cantilever arm turnover device provided in this disclosure first assembles the cantilever arm and the transfer template to form a cantilever arm assembly. Multiple cantilever arm assemblies can be assembled in the factory first. Then, multiple cantilever arm assemblies are stacked on the support frame of the cantilever arm turnover device, and the transfer templates of adjacent cantilever arm assemblies are interlocked to ensure the stability of the stacked cantilever arm assemblies. Then, by rotating the sleepers set vertically on the support frame, the cantilever arm tubes that extend horizontally from the transfer template are horizontally inserted into the support grooves at the corresponding height. The sleepers support the cantilever arm tubes of multiple cantilever arm assemblies, thereby achieving the stable placement of multiple cantilever arm assemblies on the cantilever arm turnover device. Then, the multiple cantilever arm assemblies and the cantilever arm turnover device as a whole are transported, realizing the efficient transportation of cantilever arm assemblies. This solves the problem in the prior art that it is difficult to efficiently transport cantilever arms from the factory to the construction site. In addition, the sleepers provided in this disclosure can provide effective support for the cantilever arm and prevent deformation of the cantilever arm due to vibration during transportation. Therefore, this disclosure not only saves manpower by enabling the assembly of the cantilever arm directly in the factory, but also ensures that the shape of the cantilever arm will not change during transportation, thereby reducing both labor costs and transportation losses, and ultimately achieving the goal of improving economic efficiency.

[0035] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0036] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0037] like Figure 1 and Figure 2As shown, this disclosure provides a cantilever arm turnover device, including: a support frame 1, which in this embodiment is a frame structure to reduce its own weight and facilitate forklift transportation to a designated location; multiple transfer templates 2, which are used to install and fix the cantilever arm 5 and form a cantilever arm assembly with the cantilever arm 5. When the cantilever arm 5 is installed on the transfer template 2, the cantilever arm tube of the cantilever arm 5 extends horizontally out of the transfer template 2; multiple cantilever arm assemblies can be stacked on the support frame 1, and adjacent transfer templates 2 are interlocked with each other. Through the setting of the support frame 1, this disclosure allows multiple transfer templates 2 assembled with cantilever arms 5 to be stacked, and adjacent transfer templates 2 can be interlocked with each other, thereby ensuring the stability of multiple cantilever arm assemblies stacked on the support frame 1, ultimately forming an integrated cantilever arm turnover device for transport from the factory to the construction site.

[0038] Specifically, the cantilever arm 5 typically includes a cantilever tube and a ceramic rod connected to one end of the cantilever tube. The cantilever tube is usually quite long. The ceramic rod of the cantilever arm 5 is fixed to the transfer template 2, and the end of the cantilever tube away from the ceramic rod extends out of the transfer template 2, forming a cantilever structure. Due to the above-mentioned structure of the cantilever arm 5, the cantilever tube is prone to deformation due to vibration during transportation, thereby affecting the quality and accuracy of the cantilever arm 5.

[0039] Based on this, the wrist arm turnover device of this embodiment further includes a sleeper 3. The sleeper 3 is vertically arranged on the support frame 1 and can rotate horizontally relative to the support frame 1. Multiple support grooves 31 are respectively provided on both sides of the sleeper 3 along the height direction. The height of the support grooves 31 is adapted to the diameter of the wrist arm tube, that is, the height of the support grooves 31 is slightly larger than the diameter of the wrist arm tube. The dimensions of the support grooves 31 on both sides are also adapted to the shape of the wrist arm tube at this position, so that the wrist arm tube can be smoothly inserted into the support grooves 31, thereby supporting the wrist arm tube using the sleeper 3. Furthermore, the height of the support grooves 31 should not be too large to avoid the problem of the wrist arm tube coming out of the support grooves 31 when subjected to large vibrations. Rotating the sleeper 3 allows the wrist arm tube of the wrist arm 5 to be horizontally inserted into the support groove 31 of the corresponding height, so that the wrist arm tube is supported by the sleeper 3. Specifically, before the transfer template 2 is installed, the sleeper 3 is set along the length of the support frame 1, or the sleeper 3 is removed from the support frame 1 so that the setting of the sleeper 3 does not affect the stacking of the transfer template 2 on the support frame 1. After the transfer template 2 is installed, the sleeper 3 is rotated to be set along the width of the support frame 1, or the sleeper 3 is installed on the support frame 1 and rotated to be set along the width of the support frame 1 so that the sleeper 3 provides further support for the cantilever tube of the cantilever arm 5 and avoids deformation of the cantilever tube of the cantilever arm 5 due to vibration during transportation.

[0040] Specifically, regarding the installation relationship between the cantilever arm 5 and the sleeper 3, such as Figure 1 and Figure 5 As shown, the cantilever arm 5 includes a flat cantilever arm 51 and an inclined cantilever arm 52. Both the flat cantilever arm 51 and the inclined cantilever arm 52 include an insulator and a cantilever tube connected to the insulator. The insulator is fixed on the transfer template 2, and the cantilever tube extends horizontally out of the transfer template 2. The cantilever tubes of the flat cantilever arm 51 and the inclined cantilever arm 52 are gradually moved closer together along the direction of extending out of the transfer template 2. The sleeper 3 is located in the angled space formed between the cantilever tubes of the flat cantilever arm 51 and the inclined cantilever arm 52. The cantilever tubes of the flat cantilever arm 51 and the inclined cantilever arm 52 are respectively supported in the support grooves 31 located on both sides of the sleeper 3. Through the constraint between the cantilever tube and the sleeper 3, the cantilever tube on the transfer template 2 can be supported by the sleeper 3. Thus, the transfer template 2 supports one end of the cantilever arm 5, and the sleeper 3 supports the other end of the cantilever arm 5, so that the cantilever arm 5 on the support frame 1 is stably supported and the cantilever tube is prevented from deforming. Furthermore, since the sleeper 3 is located within the angled space formed between the arm tube of the flat arm 51 and the arm tube of the inclined arm 52, when the sleeper 3 is rotated so that the arm tubes of the flat arm 51 and the inclined arm 52 are respectively supported in the support grooves 31 located on both sides of the sleeper 3, the sleeper 3 is fixed to the support frame 1. Since the arm tubes of the flat arm 51 and the arm tubes of the inclined arm 52 restrain each other, even if vibration occurs during transportation, the arm tubes will not fall out of the support grooves 31.

[0041] In this embodiment, the support frame 1 includes a base frame 11 and two base frames 12. The two base frames 12 are located at both ends of the base frame 11 along its length, and the two base frames 12 have different heights, so that multiple cantilever arm assemblies can be divided into two groups and placed on the two base frames 12 in a staggered manner. The two groups of cantilever arm assemblies are arranged alternately in a staggered manner along the height direction. By adjusting the height of the two base frames 12 to make them different, the cantilever arms 5 can be placed in a staggered manner, allowing more cantilever arms 5 to be transported in a limited transport space.

[0042] Specifically, there are two sleepers 3. These two sleepers 3 are sequentially arranged on the base frame 11 along its width direction to support the cantilever tubes of the cantilever assembly placed on the two base frames 12. The two sleepers 3 support the cantilever arms 5 on both sides. During installation, the sleepers 3 are initially placed along the length direction of the base frame 11. When the cantilever arms 5 are stacked, the sleepers 3 are always placed in the gaps between the multiple cantilever arms 5, ensuring that they do not contact any part of the cantilever arms 5. After all the cantilever arms 5 are installed, the workers rotate the sleepers 3 from their length direction to their width direction, so that each cantilever arm 5 can be placed in the support groove 31 of the sleeper 3, preventing deformation of the cantilever arm 5 during transportation.

[0043] Furthermore, the support grooves 31 on the two sleepers 3 are correspondingly arranged one-to-one along the height direction of the sleepers 3. The arm tubes of multiple arm assemblies arranged sequentially along the height direction in each group are respectively supported on the support grooves 31 spaced apart along the height direction, and the arm tubes of the two groups of arm assemblies are respectively supported on the support grooves 31 at different height positions. For example... Figure 2 As shown, in this embodiment, the two sleepers 3 are identical in shape, and the support grooves 31 on the two sleepers 3 correspond one-to-one along the height direction of the sleepers 3. Since the bracket arms 5 placed at both ends of the base frame 11 are staggered, the height of each bracket arm 5 is not exactly the same. In order to ensure that each bracket arm 5 is supported, multiple support grooves 31 are provided on both sides of the sleeper 3. The number of support grooves 31 is greater than the number of bracket arms 5, so that regardless of the height of the bracket arm 5, it can be supported by the appropriate support grooves 31. In other embodiments, the position of the support grooves 31 can also be determined according to the spacing between the upper and lower stacked bracket arms 5. This arrangement will not have redundant support grooves 31 and can adapt to the size and shape of certain bracket arms 5.

[0044] In this embodiment, the sleeper 3 and the base frame 11 are connected by a rotating member 4, such as... Figure 3 As shown, the lower end of the rotating part 4 is embedded in the base frame 11, and the upper end of the rotating part 4 is detachably connected to the sleeper 3. Through the connection of the rotating part 4, the sleeper 3 can rotate around the rotating part 4 so that the sleeper 3 is placed in the gap between the arms 5, or after rotation, the support groove 31 supports the arms 5.

[0045] To provide further support for the sleeper 3 and the base frame 11, multiple bolts are detachably inserted between the sleeper 3 and the base frame 11, with the bolts respectively located on both sides of the rotating component 4. Multiple bolt holes are provided on the base frame 11. Before the sleeper 3 rotates, when it is positioned along the length of the base frame 11, the sleeper 3 is connected to the base frame 11 by bolts to fix the sleeper 3 in this position. Then, the cantilever arms 5 are stacked and installed. After the cantilever arms 5 are placed, the bolts are removed. Then, the sleeper 3 is rotated along the width of the base frame 11. After the support groove 31 can support the cantilever arms 5, the sleeper 3 is then fixed to the base frame 11 by bolts.

[0046] Specifically, the connection between the base frame 12 and the transfer template 2 is achieved by having multiple first through holes 121 on the base frame 12 and multiple second through holes 211 on the transfer template 2. The first through holes 121 and second through holes 211 correspond one-to-one, and bolts are inserted into the first through holes 121 and second through holes 211 to connect the base frame 12 and the transfer template 2. When the transfer template 2 needs to be installed, the bottommost template is fixed to the base frame 12 with bolts, and the other transfer templates 2 are connected to the bottommost transfer template 2 to achieve a stacked arrangement.

[0047] In this embodiment, the cantilever arm turnover device also includes two locking members 13, which are respectively disposed on both sides of the base frame 11. The locking members 13 are used to lock the base frame 11 to the transport vehicle. After the cantilever arm 5 is fully installed, the base frame 11, the base frame 12 and the transfer template 2 are transported as a whole to the transport vehicle by a forklift, and the base frame 11 and the transport vehicle are locked by the locking members 13. Then the transportation begins to complete the process from the factory to the construction site.

[0048] Furthermore, in this embodiment, the base frame 11 is also equipped with multiple lifting components 14 to achieve the lifting of the cantilever arm turnover device. The lifting components 14 can be lifting eye bolts or lifting eye bolts that are integrally formed with the base frame 11. In this embodiment, the base can be lifted to a designated position through the cooperation of the lifting components 14 and the lifting device, thereby realizing subsequent installation.

[0049] In addition, a cushioning element is attached to the surface of the support groove 31. The cushioning element prevents damage to the wrist arm 5 caused by contact with the sleeper 3 when it is positioned in the support groove 31, thus avoiding any impact on its performance. In this embodiment, the cushioning element can be made of silicone or fabric.

[0050] In this embodiment, as Figures 4 to 6 As shown, the transfer template 2 includes a mounting base 21 and a wrist arm clamping device 22 disposed on the mounting base 21. The wrist arm clamping device 22 is used to clamp the wrist arm 5. A plurality of vertically arranged plug-in members 23 are provided at the periphery of the mounting base 21. The plug-in members 23 protrude vertically from the upper surface of the mounting base 21 at a predetermined height. The upper end of the plug-in member 23 forms a first plug-in part 231, and the lower end of the plug-in member 23 extends downward to the lower part of the mounting base 21. The lower end of the plug-in member 23 forms a second plug-in part 232. The first plug-in part 231 of one transfer template 2 is adapted to be plugged into and cooperate with the second plug-in part 232 of another transfer template 2.

[0051] Specifically, connector 23 includes a first insertion part 231 and a second insertion part 232. The first insertion part 231 is a sleeve, and the second insertion part 232 is a connecting rod. The upper end of the sleeve has a first through hole for inserting a locking pin, and the lower end of the connecting rod has a second through hole for inserting a locking pin. In this embodiment, the sleeve is a hollow structure. After the connecting rod is inserted into the sleeve, the first and second through holes will align, and then the locking pin is inserted to fix the position of the sleeve and the connecting rod. In addition, in this embodiment, the sleeve and the connecting rod are not limited to being fixed by a locking pin; they can also be fixed by bolts. The bolts pass through the first and second through holes, and then are fixed by nuts, thereby fixing the position of the mounting rod and the sleeve. The specific choice can be made according to the actual working conditions.

[0052] Furthermore, the wrist arm clamping device 22 is provided in two sets. The two sets of wrist arm clamping devices 22 are used to clamp the wrist arm tube of the flat wrist arm 51 and the wrist arm tube of the inclined wrist arm 52, respectively. The two sets of wrist arm clamping devices 22 are rotatably connected to the mounting base 21 through the connecting shaft 24, so that the wrist arm clamping device 22 can rotate around the connecting shaft 24 on the mounting base 21. The mounting base 21 is provided with mounting holes 212 for mounting the connecting shaft 24. One of the two mounting holes 212 is an elongated hole, so that the mounting position of the connecting shaft 24 in the elongated hole is adjustable.

[0053] Two sets of wrist and arm clamping devices 22 are rotatably connected to the mounting base 21 via connecting shafts 24, so that the wrist and arm clamping devices 22 can rotate around the connecting shafts 24 on the mounting base 21. During use, the two sets of wrist and arm clamping devices 22 rotate around the connecting shafts 24 to form different angles between them to adapt to different wrist and arm shapes.

[0054] During use, not only do the angles of the inclined arm 52 and the flat arm 51 need to be adjusted, but the distance between the inclined arm 52 and the flat arm 51 also needs to be adjusted adaptively. Therefore, mounting holes 212 for mounting the connecting shaft 24 are provided on the mounting base 21. One of the two mounting holes 212 is an elongated hole so that the mounting position of the connecting shaft 24 in the elongated hole is adjustable. Specifically, in this embodiment, the mounting hole 212 for connecting the flat arm 51 is a round hole, and the mounting hole 212 for connecting the inclined arm 52 is an elongated hole. The connecting shaft 24 set in the elongated hole can move along the length of the elongated hole to adjust the distance between the inclined arm 52 and the flat arm 51. Of course, the mounting hole 212 for connecting the flat arm 51 can also be set as an elongated hole to adjust the distance between the flat arm 51 and the inclined arm 52. In other embodiments, both mounting holes 212 can be set as elongated holes to achieve a wider range of adjustment.

[0055] By using the connecting shaft 24 and the elongated hole in this embodiment, the relative angle and relative spacing of the two cantilever arms 5 can be adjusted, so that the cantilever arm transfer template 2 can adapt to different cantilever arm angles and shapes, thereby improving the adaptability and versatility of the cantilever arm transfer template 2. Furthermore, the cantilever arm transfer template 2 is not only suitable for cantilever arm assembly on the construction site, but also for cantilever arm assembly in the factory, playing a supporting role for the cantilever arm 5 and facilitating the transfer of the cantilever arm 5. This allows the cantilever arm 5 to be transferred from the factory to the construction site for installation after assembly, reducing the number of on-site construction personnel, improving the safety of on-site construction, and simplifying the structure of the cantilever arm installation equipment for on-site construction, thus improving the efficiency of cantilever arm installation.

[0056] To reduce friction between the wrist arm gripping device 22 and the mounting base 21 when the wrist arm gripping device 22 rotates around the connecting shaft 24, rollers are provided at the bottom of each of the two wrist arm gripping devices 22, so that the rollers can roll on the mounting base 21 when the wrist arm gripping device 22 rotates around the connecting shaft 24. Specifically, multiple rollers can be provided in this embodiment to maintain the stability of the wrist arm gripping device 22 during movement. Moreover, to further reduce friction, lubricating oil can be applied to the outer surface of the rollers.

[0057] The cantilever arm turnover device provided in this disclosure first stacks the cantilever arm assembly, consisting of the transfer template 2 and the cantilever arm 5, and then installs the bottom cantilever arm assembly onto the base frame 12. The base frame 11 is then locked to the transport vehicle. This solves the problem in the prior art where the cantilever arm 5 is difficult to transport from the factory to the construction site. Furthermore, the sleepers 3 provided in this disclosure provide further support for the cantilever arm 5, preventing deformation due to vibration during transportation. Therefore, this disclosure not only saves manpower by allowing direct installation in the factory but also ensures that the shape of the cantilever arm 5 does not change during transportation, reducing both labor costs and transportation losses, ultimately achieving the goal of improving economic efficiency.
