Description

Technical Field

[0001] This invention relates to the field of power operation technology, specifically to a mechanical claw for climbing power angle steel towers. Background Technology

[0002] Angle steel towers are an indispensable part of power transmission infrastructure. They are used to erect high-voltage transmission lines at a height of approximately 50 meters, effectively preventing ground objects from obstructing or interfering with the lines, and increasing the distance between the lines and the ground, thus enhancing the safety of personnel on the ground. Due to their height and the often slanted and narrow angle steel used to construct the towers, securing certain work equipment is difficult. Therefore, externally constructed work platforms are needed to hold the equipment or allow personnel to stand and work.

[0003] Patent application CN116279878A discloses a climbing work platform that uses two clamping devices to alternately grip and control the entire device to climb upwards. Similar structures are shown in patents CN216067470U and CN115229482A. In existing clamping mechanisms, the grippers are typically hinged to the platform, and their ends are connected to a servo motor and a lead screw for transmission. The servo motor drives the lead screw, causing the end of the gripper to move forward or backward. The gripper rotates around its hinged position with the platform, opening or closing to clamp or release the angle steel.

[0004] Although the above-mentioned technical solutions can meet the requirements for clamping angle steel, the angle steel in power towers is usually quite dense, especially the angle steel near the top of the power tower; and the existing climbing equipment requires a large fan-shaped space for the claws during operation, which means that the claws are prone to spatial interference with the surrounding angle steel, which is not conducive to the claws completing the opening action. Summary of the Invention

[0005] The purpose of this invention is to provide a mechanical claw for climbing power angle steel towers, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mechanical claw for climbing power angle steel towers, comprising a base, a clamping mechanism, and a pressing mechanism, wherein both the clamping mechanism and the pressing mechanism are disposed on the base, the clamping mechanism comprising two claws arranged in a mirror-symmetrical manner; a sliding rod extending vertically is provided at one end of each claw facing the base, and two first sliding grooves are symmetrically arranged on the plane of the base, the two first sliding grooves being "V" shaped and opening inward, one end of the sliding rod extending into the first sliding groove and slidingly engaging with the first sliding groove; a first driving assembly for driving the sliding rod to reciprocate along the first sliding groove is also provided on the base; The base is provided with a limiting guide rod corresponding to the gripper, the limiting guide rod extends vertically, and the gripper is provided with a sliding hole that slides with the limiting guide rod; The clamping mechanism includes a clamping block that is slidably disposed on a base in the front-back direction, and a second driving component for driving the clamping block to move is also disposed on the base.

[0007] Preferably, the first driving component is a linear driving module fixed on a base. The base is provided with a linkage member that can slide back and forth. The linkage member is provided with a second sliding groove that extends laterally. The other end of the sliding rod extends into the second sliding groove and slides in cooperation with the second sliding groove. The driving end of the linear driving module is connected to the linkage member.

[0008] Preferably, the upper and lower ends of the slide bar are respectively provided with an upper bearing and a lower bearing, the lower bearing is used to slide with the first slide groove, and the upper bearing is used to slide with the second slide groove.

[0009] Preferably, a rotating seat is rotatably provided on the outer side of the limiting guide rod, and a through hole for the gripper to pass through is provided on the rotating seat.

[0010] Preferably, bearing wheels are respectively provided on the rotating seat on the left and right sides of the through hole, and the circumferential surface of the bearing wheels is in close contact with the gripper.

[0011] Preferably, wear-resistant blocks are provided on the left and right sides of the upper and lower edges of the inlet and outlet ends of the through hole, respectively.

[0012] Preferably, the second drive component is a linear drive module fixed on the base, and the drive end of the linear drive module is connected to the clamping block.

[0013] Preferably, the rear side of the clamping block is further provided with a rearwardly extending guide strip, and the base is further provided with a guide member that slides in cooperation with the guide strip.

[0014] Preferably, the front side of the clamping block is provided with a V-shaped groove with a groove angle of 90 degrees.

[0015] Preferably, the rear side of the clamping block is further provided with a rearwardly extending guide rod, and the base is provided with a guide hole that slides with the guide rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when the action of the gripper changes from clamping the angle steel to releasing the angle steel, compared with the traditional gripper that unfolds directly and is of the same size, the space required for the unfolding of this gripper is greatly reduced. While not hindering the gripper's clamping function, it reduces the space occupied by the gripper's movement and reduces the possibility of interference between the gripper and the external angle steel tower structure.

[0017] 2. In this invention, the end of the gripper is provided with a barb structure, which facilitates abutting against the back of the angle steel. When the gripper moves from back to front along the rear sliding groove section, the gripper makes an approximately translational movement. With the oblique translational posture, the two grippers are controlled to move closer or further apart from each other, avoiding interference between the barb at the end of the gripper and the angle steel to be clamped, thereby improving the tightness of the gripper holding the angle steel.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] 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.

[0022] like Figures 1 to 9 As shown, a mechanical claw for climbing power angle steel towers includes a base 1. The base 1 is used to install a clamping mechanism 2. At the same time, the base 1 serves as a transition connection seat to be fixedly connected to external working equipment. The base 1 is provided with mounting holes for connecting external working equipment. The mounting holes are usually located on the upper surface of the base 1 so as to facilitate the use of fasteners (bolts, etc.) to fix the base to the corresponding working equipment.

[0023] It also includes a clamping mechanism 2 and a pressing mechanism 3; both the clamping mechanism 2 and the pressing mechanism 3 are mounted on the base 1; the clamping mechanism 2 is used to clamp the inner side of the angle steel tower block, and the pressing mechanism 3 is used to press against the outer side of the angle steel tower block. The two work together to achieve the purpose of pressing against and clamping the angle steel.

[0024] The clamping mechanism 2 includes two grippers 21 arranged in a mirror-symmetrical manner; one end of each gripper 21 facing the base 1 is provided with a slide rod 24 extending in the vertical direction; two first slide grooves 15 are symmetrically arranged on the plane of the base 1, the two first slide grooves 15 are V-shaped and their openings face inward (with the opposite side of the two first slide grooves 15 as the inner side); one end of the slide rod 24 extends into the first slide groove 15 and slides in cooperation with the first slide groove 15; the base 1 is also provided with a first driving component for driving the slide rod 24 to reciprocate along the first slide groove 15.

[0025] The base 1 is provided with vertically extending limiting guide rods 45 on both sides. The limiting guide rods 45 are symmetrically arranged and correspond one-to-one with the grippers 21. The grippers 21 are provided with sliding holes 27 that slide in cooperation with the limiting guide rods 45.

[0026] The clamping mechanism 3 includes a clamping block 31 that is slidably disposed on the base 1 in the front-back direction, and the base 1 is also provided with a second driving component for driving the clamping block 31 to move.

[0027] In one specific embodiment, the base 1 includes an upper plate 11, a lower plate 12, and a connecting plate 13, wherein the upper plate 11 and the lower plate 12 are arranged parallel to each other, and the connecting plate 13 is used to transitionally connect the upper plate 11 and the lower plate 12. Specifically, the connecting plate 13 extends vertically, and its top end is fixedly connected to the rear edge of the upper plate 11; its bottom end is fixedly connected to the rear edge of the lower plate 12. A cavity 14 is formed between the upper plate 11 and the lower plate 12 for mounting the clamping mechanism 2 and the pressing mechanism 3. Because the clamping mechanism 2 operates within the cavity 14 between the upper plate 11 and the lower plate 12, it will not affect the external working equipment fixed on the upper surface of the base 1, allowing the upper surface of the base 1 to be used for placing the working equipment of the power tower or for standing workers.

[0028] Specifically, in this embodiment, the first slide groove 15 is disposed on the upper surface of the lower plate 12. Since the first slide groove 15 has a "V"-shaped structure, it forms two segments sequentially from back to front: a rear slide groove segment 151 and a front slide groove segment 152. The junction of the rear slide groove segment 151 and the front slide groove segment 152 is rounded to improve the smoothness of the slide rod 24 when sliding at the junction of the rear slide groove segment 151 and the front slide groove segment 152.

[0029] Preferably, the first driving component is a linear drive module fixed on the base 1, such as any of a hydraulic cylinder, pneumatic cylinder, or lead screw motor. The base 1 is provided with a sliding linkage 23, which has a second sliding groove 25 extending laterally. The other end of the sliding rod 24 extends into the second sliding groove 25 and slides within it. The main body of the linear drive module is fixed to the base 1, and the driving end of the linear drive module is connected to the linkage 23.

[0030] Taking the hydraulic cylinder as an example of a linear drive module: the hydraulic cylinder is fixed on the connecting plate 13, the drive arm of the hydraulic cylinder passes through the connecting plate 13 and extends into the cavity 14, and the drive arm of the hydraulic cylinder is fixedly connected to the linkage 23 by bolts.

[0031] Taking a cylinder as an example in the linear drive module: the cylinder is fixed on the connecting plate 13, the drive arm of the cylinder passes through the connecting plate 13 and extends into the cavity 14, and the drive arm of the cylinder is fixedly connected to the linkage 23 by bolts.

[0032] Taking a lead screw motor as an example of a linear drive module: the corresponding drive motor inside the lead screw motor is fixed on the connecting plate 13, the corresponding lead screw inside the lead screw motor passes through the connecting plate 13 and extends into the cavity 14, and the linkage 23 is connected to the lead screw through the lead screw slider.

[0033] Specifically, in this embodiment, the linkage 23 is slidably disposed on the lower side of the upper plate 11. The lower side of the upper plate 11 is provided with two linear guide rails that extend forward and backward and are parallel to each other. The top of the linkage 23 is provided with a slider corresponding to the linear guide rail, and the slider is slidably connected to the corresponding linear guide rail.

[0034] The linkage 23 is driven to move back and forth by the linear drive module. As the linkage 23 moves back and forth, it also moves the slide rod 24 back and forth. The slide rod 24 moves along the first slide groove 15 with the gripper. Since the first slide groove 15 has a "V" shaped structure, the slide rod 24 will move laterally during its back and forth movement. Therefore, the second slide groove 25 extends laterally and slides with the other end of the slide rod 24 to accommodate the lateral movement of the slide rod 24.

[0035] Furthermore, the upper and lower ends of the slide rod 24 are respectively provided with an upper bearing 26 and a lower bearing 28. The lower bearing is used to slide with the first slide groove 15, and the upper bearing 26 is used to slide with the second slide groove 25. The upper bearing 26 and the lower bearing 28 help the slide rod 24 to slide better with the first slide groove 15 and the second slide groove 25, thereby reducing sliding friction.

[0036] Furthermore, to stabilize the connection between the upper plate 11 and the lower plate 12 and enhance the stability and load-bearing capacity of the overall frame of the base 1, a support plate 19 is provided between the upper plate 11 and the lower plate 12. The support plate 19 is located on the side away from the connecting plate 13, that is, on the front side of the upper plate 11 and the lower plate 12. Specifically, the support plate 19 extends vertically, with its top end fixedly connected to the front edge of the upper plate 11 and its bottom end fixedly connected to the front edge of the lower plate 12.

[0037] In one specific embodiment, a support base 18 for fixing and installing the limiting guide rod 45 is provided between the upper plate 11 and the lower plate 12. Two limiting guide rods 45 and two corresponding support bases 18 are provided, each corresponding to a gripper 21. The two support bases 18 are located on the left and right sides of the upper plate 11 (or lower plate 12), respectively. The top end of the support base 18 is fixedly connected to the upper plate 11 by bolts, and the bottom end of the support base 18 is fixedly connected to the lower plate 12 by bolts. The upper and lower ends of the limiting guide rod 45 are fixedly connected to the corresponding support base 18.

[0038] In this embodiment, as Figure 5As shown, the gripper 21 comprises a gripper arm 211 and a gripper head 212, extending from back to front. The gripper arm 211 gradually bends and extends outward from back to front (with the side opposite to each other of the two grippers 21 as the inner side), and the gripper head 212 gradually bends and extends inward from back to front (with the side opposite to each other of the two grippers 21 as the inner side). A barb 213 is provided at the end of the gripper head 212, which is used to hook the inner edge of the angle iron. The sliding hole 27 is preferably provided on the gripper arm 211, and when the sliding rod 24 is located in the rear sliding groove section 151, the extension direction of the sliding hole 27 is parallel to the extension direction of the rear sliding groove section 151. The purpose of this design is to make the gripper 21 move approximately in a translational motion as it moves from back to front along the rear slide section 151 (i.e., the slide bar 24 moves from back to front along the rear slide section 151). By moving in an oblique translational manner, the two grippers 21 are controlled to move closer or further apart, avoiding interference between the barb 213 at the end of the gripper 21 and the angle steel to be clamped. Specifically, it avoids interference between the barb 213 and the angle steel during the opening or closing of the gripper 21, making it easier for the gripper 21 to mechanically engage with the angle steel. When the gripper 21 moves from back to front in the corresponding front slide section 152 within the first slide groove 15 (i.e., the slide rod 24 moves from back to front along the front slide section 152), under the guiding action of the front slide section 152 and the limiting and guiding action of the limiting guide rod 45, the gripper 21 performs an outward flipping action, causing the barbed ends (gripper heads 212) of the two grippers 21 to move away from each other, forming an unfolding action of the gripper heads 212; on the other hand, the gripper arms 211 of the grippers 21 move closer to each other, forming a retracting action of the gripper arms 211. Since the gripper heads 212 and gripper arms 211 are an integral unit, the two gripper heads 212 will also move closer to each other and retract to a certain extent while unfolding (e.g., ...). Figures 10 to 13 , Figures 14 to 17 (As shown). In this way, when the action of gripper 21 changes from clamping the angle steel to releasing the angle steel, compared with the traditional gripper that unfolds directly and is of the same size, the space required for the unfolding of this gripper 21 is greatly reduced. While not hindering the clamping function of gripper 21, the space occupied by the movement of gripper 21 is reduced, and the possibility of interference between gripper 21 and the external angle steel tower structure is reduced.

[0039] When the gripper 21 moves from front to back along the rear slide section 151, the gripper 21 reverses the above-mentioned movement action, and the gripper 21 changes from the unfolded state back to the clamped state.

[0040] Furthermore, such as Figure 7 and Figure 8As shown, a rotating seat 4 is rotatably mounted on the outer side of the limiting guide rod 45, and a through hole 41 for the gripper 21 to pass through is provided on the rotating seat 4. Specifically, bearing seats 44 are respectively provided at the upper and lower ends of the limiting guide rod 45, and the limiting guide rod 45 is rotatably connected to the rotating seat 4 through the bearing seats 44. Achieving rotational engagement between workpieces through bearing seats is a conventional existing technology, and the specific arrangement will not be described in detail.

[0041] The rotating seat 4 provides stable guidance and support for the movement of the gripper 21. The rotating seat 4 is rotatable relative to the limiting guide rod 45 to accommodate the rotational deflection of the gripper 21 during displacement.

[0042] Furthermore, bearing wheels 42 are respectively provided on the rotating seat 4 on the left and right sides of the through hole 41. The axis of the bearing wheels 42 extends vertically, and the circumferential surface of the bearing wheels 42 is in close contact with the corresponding gripper arm 211 inside the gripper 21. The bearing wheels 42 on both sides of the through hole 41 can help the gripper 21 slide more smoothly in the rotating seat 4, reduce the sliding friction between the gripper 21 and the inner wall of the through hole 41, and extend the service life.

[0043] In this example, considering the friction between the upper and lower surfaces of the gripper 21 and the upper and lower inner walls of the through hole 41, wear-resistant and easily replaceable L-shaped wear-resistant blocks 43 are respectively provided on the left and right sides of the upper and lower edges of the inlet and outlet ends of the through hole 41. That is, the wear-resistant blocks 43 are located at the four corners of the inlet and outlet ends, and the wear-resistant blocks 43 protrude into the through hole 41 relative to the inner wall of the through hole 41, so that the gripper 21 can directly contact the wear-resistant blocks 43 and avoid contact with the inner wall of the through hole 41. The wear-resistant blocks 43 are fixed to the rotating seat 4 by detachable screws, which facilitates the replacement of the wear-resistant blocks 43.

[0044] The wear-resistant block 43 is preferably made of POM (polyoxymethylene) material, which has both high strength, high rigidity and good wear resistance.

[0045] Meanwhile, the support seat 18 can prevent the pressure on the upper plate 11 from being transmitted to the lower plate 12 through the limit guide rod 45, thus avoiding any impact on the limit guide rod 45 and the rotating seat 4 and ensuring the stable clamping of the gripper 21.

[0046] As one specific implementation method, such as Figures 2 to 3 and Figure 7 As shown, the second drive component is a linear drive module fixed on the base 1, such as any one of a hydraulic cylinder or a pneumatic cylinder.

[0047] Taking the linear drive module with a hydraulic cylinder as an example: the hydraulic cylinder is fixed at the bottom of the lower plate 12, and the drive arm of the hydraulic cylinder is fixedly connected to the clamping block 31 by bolts.

[0048] Taking the linear drive module with a cylinder as an example: the cylinder is fixed at the bottom of the lower plate 12, and the drive arm of the cylinder is fixedly connected to the clamping block 31 by bolts.

[0049] Furthermore, a rearwardly extending guide rod 33 is provided on the rear side of the clamping block 31. Two guide rods 33 are preferably provided, and a guide hole 110 is provided on the base 1 to slide in conjunction with the guide rod 33. The guide hole 110 is specifically provided on the support plate 19. The main function of the guide rod 33 is to provide movement guidance for the clamping block 31, ensuring that the clamping block 31 slides back and forth in a straight line, making it less prone to deflection.

[0050] Furthermore, a rearwardly extending guide strip 35 is provided on the rear side of the clamping block 31. The guide strip 35 has a rectangular cross-section and is located near the bottom end of the clamping block 31. A guide member 34 is also provided on the base 1, which slides and engages with the guide strip 35. The guide member 34 contains a rectangular channel with the same shape as the guide strip 35 and slides and engages with it. The guide strip 35 firstly serves to stabilize and guide the movement of the clamping block 31, and secondly, it enhances the overall structural stability and stress resistance of the clamping block 31.

[0051] Furthermore, wear-resistant and easily replaceable wear-resistant parts are provided on the left and right sides of the upper and lower edges of the inlet and outlet ends of the rectangular channel of the guide 34. The design of the wear-resistant parts is the same as that of the wear-resistant block 43, and their function is the same as that of the wear-resistant block 43. The specific arrangement is the same as that of the wear-resistant block 43, which will not be described in detail here.

[0052] Furthermore, the front side of the clamping block 31 is provided with a V-shaped groove with a groove angle of 90 degrees, which is used to cooperate with the outer side of the angle steel, so that the contact area between the clamping block 31 and the outer side of the angle steel is larger, generating stronger friction and improving the clamping force on the angle steel of the tower.

[0053] When this mechanical gripper clamps the angle steel of the tower, if Figure 18 As shown, the jaw 21 is used to clamp the edge of the angle steel, the barb 213 is used to hook the inner side of the angle steel, and the clamping block 31 is used to clamp the right angle of the outer side of the angle steel. The angle steel is clamped under the clamping action of the jaw 21 and the clamping block 31.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
