Therefore, it has repeated use. However, in reality, in order to improve the stability of the pole, some poles will set the diameter of the pole to gradually increase from top to bottom, which results in a certain gap between some pole clamps and the poles after clamping, resulting in the risk of the pole clamp falling loose during use.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] See also Figure 1-9, a pole clamp with a stable clamping force provided by an embodiment of the present invention comprises: a detachably connected first ear plate 1 and a second ear plate 2, a positioning sleeve 3, a locking mechanism 5, and two clamp units 4 arranged in parallel up and down, the positioning sleeve 3 is fixedly connected to the second ear plate 2, each clamp unit 4 comprises a clamp steel belt 42 and a rotating shaft 41 rotatably connected to the positioning sleeve 3, one end of the clamp steel belt 42 is fixedly connected to the first ear plate 1, and the other end is wound and connected to the corresponding rotating shaft 41; the locking mechanism 5 is used to drive the two rotating shafts 41 to rotate respectively so that the two clamp steel belts 42 can clamp the pole in turn. It should be noted that a plurality of anti-skid patterns are provided on the contact surface between the two clamp steel belts 42 and the pole, and the length direction of the anti-skid patterns is parallel to the length direction of the pole. By increasing the friction resistance between the two clamp steel belts 42 and the pole, the circumferential movement of the entire device relative to the pole can be effectively prevented, thereby improving the stability.

[0021] It should be noted that a support sleeve for inserting the end of the first electric telescopic rod is fixedly connected to the bottom of the first ear plate 1. Based on this, after the staff puts the two clamping steel belts 42 on the pole at the bottom of the pole, the first ear plate 1 is installed and connected with the second ear plate 2, and after it is pushed from the bottom of the pole to the preset position by the first electric telescopic rod, the electric wrench is sent to the preset position by the second electric telescopic rod and the locking mechanism 5 is operated to drive the two rotating shafts 41 to rotate respectively so that the two clamping steel belts 42 can hold the pole in turn. At this point, the entire operation process does not require the staff to climb the pole and then use tools to drive the two clamping steel belts 42 to hold the pole in turn, which greatly improves the safety of the staff's working environment and reduces the difficulty of the staff's work.

[0022] Specifically, after the first ear plate 1 and the second ear plate 2 are fixedly connected, the two rotating shafts 41 are driven to rotate through the provided locking mechanism 5 to reel in the corresponding clamping steel belts 42, and after the two rotating shafts 41 are rotated to a certain extent, the clamping steel belt 42 located at the bottom can first clamp the pole, and then only the rotating shaft 41 located at the top is driven to continue rotating so that the clamping steel belt 42 located at the top can clamp the pole, so that the elasticity of the two clamping steel belts 42 arranged in parallel up and down can adapt to the slope of different pole surfaces, thereby reducing the gap between the clamping steel belt 42 and the sloped pole, and at the same time, the two clamping steel belts 42 can clamp different diameter parts on the same pole in turn to increase the contact area between the clamping steel belt 42 and the pole, so as to better clamp the pole, thereby reducing the risk of the entire device falling off the pole, and it can be installed at different heights on the pole with a diameter that gradually increases from top to bottom, and has high practicality. Meanwhile, during the entire operation, only the two rotating shafts 41 need to be rotated to respectively enable the two clamping steel belts 42 to respectively clamp parts of different diameters on the same pole, which is simple and convenient to operate. Moreover, the entire device is also suitable for clamping cylindrical poles, further improving the practicality of the entire device.

[0023] The locking mechanism 5 includes an operating rod 51, two threaded sleeves 52 and a clamping assembly 53. The operating rod 51 is rotatably connected to the positioning sleeve 3. The rotating shaft 41 located at the top is fixedly connected to the operating rod 51, and the rotating shaft 41 located at the bottom is rotatably connected to the operating rod 51. The two threaded sleeves 52 are slidably connected to the rotating shafts 41 in a one-to-one correspondence, and each threaded sleeve 52 is threadedly connected to the positioning sleeve 3. The clamping assembly 53 is assembled so that the two rotating shafts 41 are driven to have a clamping position and a separation position of the two rotating shafts 41 during the rotation of the operating rod 51 relative to the positioning sleeve 3. The rotation strokes of the operating rod 51 relative to the positioning sleeve 3 are as follows: the first stroke drives the two rotating shafts 41 to rotate synchronously and the corresponding threaded sleeves 52 to move upward spirally relative to the second ear plate 2 until the two rotating shafts 41 are switched from the clamping position to the separation position, and at the same time, each clamping steel belt 42 is wound on the corresponding rotating shaft 41 until the clamping steel belt 42 at the bottom clamps the pole; the second stroke only drives the rotating shaft 41 at the top to continue to rotate so that the corresponding threaded sleeve 52 continues to move upward spirally relative to the positioning sleeve 3, and at the same time drives the clamping steel belt 42 at the top to be wound on the corresponding rotating shaft 41 until it clamps the pole. Among them, it should be noted that a raised track is fixedly connected to the circumferential side surface of each rotating shaft 41, and a limiting groove for vertically sliding along the raised track is opened on the inner wall of the threaded sleeve 52 corresponding to the two rotating shafts 41. At this time, when the two threaded sleeves 52 and the positioning sleeve 3 are threadedly rotated, each threaded sleeve 52 can not only drive the corresponding rotating shaft 41 to rotate relative to the positioning sleeve 3, but also each threaded sleeve 52 will slide vertically relative to the corresponding rotating shaft 41. At this time, when the corresponding clamping steel belt 42 is clamping the parts of different diameters of the pole, the threads between each threaded sleeve 52 and the positioning sleeve 3 are matched to limit the rotation of the corresponding rotating shaft 41 relative to the positioning sleeve 3, so that the two clamping steel belts 42 can be maintained in the clamping state of clamping the parts of different diameters of the pole.

[0024] Specifically, when the staff drives the operating rod 51 to rotate relative to the positioning sleeve 3, the two rotating shafts 41 are located at the clamping position with the cooperation of the clamping assembly 53, and the two rotating shafts 41 can rotate synchronously with the operating rod 51, and the two threaded sleeves 52 will rotate along the direction of the threaded tightening of the positioning sleeve 3 until the lower clamping steel belt 42 is in the thicker part of the pole, and the lower threaded sleeve 52 will prevent the corresponding rotating shaft 41 from rotating relative to the positioning sleeve 3 so that the corresponding clamping steel belt 42 is always maintained in the thicker part of the pole. When the operating rod 51 is driven to rotate, the two The rotating shaft 41 will switch from the clamping position to the separation position, and then when the operating rod 51 continues to rotate, only the rotating shaft 41 located at the top will rotate with the operating rod 51 to make the threaded sleeve 52 continue to rotate along the direction of tightening the thread of the positioning sleeve 3 until the corresponding clamping steel belt 42 is clamped on the thinner part of the pole; the entire operation process only needs to drive the operating rod 51 to rotate along the direction of tightening the thread of the two threaded sleeves 52 and the positioning sleeve 3, which is simple to operate and does not need to operate the two rotating shafts 41 separately. This reduces the operating time of the staff to a certain extent and reduces the work intensity of the staff.

[0025] Among them, the clamping assembly 53 includes a sliding portion 532, a docking portion 534 and a first elastic member 531. The sliding portion 532 is coaxially and vertically slidably connected to the operating rod 51, and a plurality of first wedge blocks 533 are fixedly connected in a circular array on the sliding portion 532; the docking portion 534 is coaxially and fixedly connected to the rotating shaft 41 located below, and a plurality of wedge grooves 535 are provided on the docking portion 534, which are clamped and matched with each first wedge block 533 one by one; the first elastic member 531, the process of restoring its elastic deformation is used to drive each first wedge block 533 to be inserted into each wedge groove 535 so that the two rotating shafts 41 can switch from the separation position to the clamping position. Specifically, when the two rotating shafts 41 are located in the clamping position, the first wedge blocks 533 fixedly connected on the sliding part 532 are clamped in the wedge grooves 535 opened on the docking part 534, and the friction resistance between the inclined surfaces of the first wedge blocks 533 and the inclined surfaces of the wedge grooves 535 is a set threshold value. When the clamping steel belt 42 located below clamps the pole and continues to drive the operating rod 51 to rotate, when the force brought by the rotation of the operating rod 51 exceeds the friction resistance of the threshold value set between the inclined surfaces of the first wedge blocks 533 and the inclined surfaces of the wedge grooves 535, the two rotating shafts 41 will switch from the clamping position to the separation position. It should also be noted that a vertical groove is provided on the operating rod 51, and a protrusion located in the vertical groove is fixedly connected to the sliding part 532. Therefore, when the operating rod 51 rotates relative to the positioning sleeve 3, the sliding part 532 will rotate with the operating rod 51, and the two rotating shafts 41 engaged with each first wedge block 533 and each wedge groove 535 will rotate synchronously; and when the two rotating shafts 41 are switched from the engaging position to the working position, the sliding part 532 will not only rotate synchronously with the operating rod 51, but also slide vertically along the operating rod 51. The first elastic member 531 is a first spring, one end of which is fixedly connected to the sliding part 532, and the other end of which is fixedly connected to the inner wall of the positioning sleeve 3.

[0026] Among them, the first threaded portion 6 is fixedly connected to the inner wall of the positioning sleeve 3, and the second threaded portion 7 is fixedly connected to the outer wall of the sliding portion 532. In the process of switching the two rotating shafts 41 from the clamping position to the separation position, the sliding portion 532 can move up relative to the operating rod 51 until the second threaded portion 7 is threadedly engaged with the first threaded portion 6 to maintain the two rotating shafts 41 in the separation position. Among them, it should be noted that the first threaded portion 6 can be a first thread with four thread turns of a quarter turn, and the starting height of each first thread is the same, which is conducive to the second threaded portion 7 and the first threaded portion 6 being threadedly engaged with the first threaded portion 6 within a certain range of rotation. The second threaded portion 7 can be a second thread with a number of preferably 2-3 turns. It should be further noted that when each first wedge block 533 is about to disengage from each wedge groove 535, the second threaded portion 7 will be threadedly engaged with the first threaded portion 6.

[0027] Specifically, during the rotation of the operating rod 51 relative to the positioning sleeve 3, the two rotating shafts 41 at the clamping position will be first caused to rotate synchronously until the clamping steel belt 42 at the bottom clamps the thicker part of the pole, and then during the continuous rotation, each wedge block will be separated from each wedge groove 535 to switch the two rotating shafts 41 from the clamping position to the separation position, and during the switching of the two rotating shafts 41 from the clamping position to the separation position, the second threaded portion 7 will be threadedly engaged with the first threaded portion 6 to keep the two rotating shafts 41 at the separation position, so that the rotating shaft 41 at the top can drive the corresponding clamp to clamp the thinner part of the pole. The whole process can switch the two rotating shafts 41 from the clamping position to the separation position, so that the two clamping steel belts 42 can clamp the thicker part and the thinner part of the pole in turn.

[0028] Specifically, when it is necessary to operate the entire device to be disassembled, it is only necessary to reversely drive the operating rod 51. At this point, the first process is that the second threaded portion 7 is threadedly separated from the first threaded portion 6. In the second process, the elastic force of the first elastic member 531 to restore the deformation drives each wedge block to be inserted into each wedge groove 535 so that the two rotating shafts 41 are switched from the separation position to the clamping position. The third process is to continue to reversely drive the operating rod 51 so that the two rotating shafts 41 release the corresponding clamping steel belts 42 so that the two clamping steel belts 42 loosen the pole. Finally, the first ear plate 1 and the second ear plate 2 are disassembled to achieve the effect of being able to disassemble the entire device from the pole.

[0029] A locking member 8 is provided between the first ear plate 1 and the second ear plate 2 to detachably connect the first ear plate 1 and the second ear plate 2. The locking member 8 includes a second wedge block 81, a locking block 82 and a second elastic member 83. The second wedge block 81 is vertically slidably connected to the first ear plate 1; the locking block 82 is fixedly connected to the second ear plate 2, and a locking hole 84 is provided on the locking block 82; the second elastic member 83 is used to drive the second wedge block 81 to be inserted into the locking hole 84 during the process of restoring elasticity. A positioning member 9 is also provided between the first ear plate 1 and the second ear plate 2. The positioning member 9 includes a positioning plug 91 fixedly connected to the first ear plate 1, and a positioning slot 92 is provided on the second ear plate 2 for horizontal insertion of the positioning plug 91. The second elastic member 83 includes a sliding rod and a second spring. The sliding rod is vertically slidably connected to the first ear plate 1, and the second spring is sleeved on the sliding rod, with one end fixedly connected to the first ear plate 1 and the other end fixedly connected to the sliding rod.

[0030] Specifically, when the positioning block 91 is inserted into the positioning slot 92, the locking block 82 abuts against the inclined surface of the second wedge block 81 so that the slide bar compresses the second spring until the wedge block is aligned with the locking hole 84. At this time, the second spring recovers its elastic deformation so that the second wedge block 81 is inserted into the locking hole 84, thus completing the detachable connection between the first ear plate 1 and the second ear plate 2. The positioning block 91 and the positioning slot 92 can prevent the first ear plate 1 and the second ear plate 2 from sliding up and down.

[0031] Among them, anti-skid silicone pads are fixedly connected to the inner side walls of the first ear plate 1 and the second ear plate 2. The anti-skid silicone pads can increase the friction between the pole and the first ear plate 1 and the second ear plate 2, thereby further improving the stability of the entire device during installation.

[0032] As an operating method provided by the present invention, it is implemented based on a pole clamp with a stable clamping force, and includes the following steps: S1, sleeve the entire device on the lower section of the pole, and connect the first ear plate 1 and the second ear plate 2; S2, drive the entire device to a preset height of the pole through an external first electric telescopic rod; S3, push the electric wrench to cooperate with the operating rod 51 through an external second electric telescopic rod; S4, drive the operating rod 51 to rotate relative to the positioning sleeve 3 through the electric wrench so that the two clamp steel belts 42 clamp the pole in turn.

[0033] Specifically, a hexagonal hole is provided at the bottom of the operating rod 51. After the first electric telescopic rod is inserted into the supporting sleeve and the entire device mounted on the pole is pushed to a certain height, the operating rod 51 can be driven to rotate relative to the positioning sleeve 3 by inserting the hexagonal head of the electric wrench into the hexagonal hole through the second electric telescopic rod. At this point, the staff only needs to be on the ground to achieve the effect of clamping the entire device on the pole. In order to further facilitate the operation of the staff, the first electric telescopic rod and the second electric telescopic rod can be fixedly connected, and the electric wrench is arranged on the second electric telescopic rod. At this point, after the staff puts the entire device on the pole at the bottom of the pole and connects the first ear plate 1 with the second ear plate 2, one end of the first electric telescopic rod is inserted into the supporting sleeve and the hexagonal head of the electric wrench of the second electric telescopic rod is inserted into the hexagonal hole. Then, the first electric telescopic rod and the second electric telescopic rod are operated simultaneously to push the entire device to a preset height. Finally, the staff holds the first electric telescopic rod with one hand to maintain the entire device at the preset height, and the other hand can directly operate the cooperation between the electric wrench and the hexagonal hole to rotate the operating rod 51 relative to the positioning sleeve 3, so that the two clamping steel belts 42 can be clamped in turn at parts of different diameters of the pole.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
