Example 1
The utility model provides a high tension transmission line overhauls conveyor, is including being provided with transmission line 1 of high tension line conductor spacer 2, still includes braced frame 3, braced frame 3 cup joints in transmission line 1's the outside and can move on transmission line 1, braced frame 3 sets up two, and connects through connecting rod 4 between two braced frame 3, braced frame 3's interval can be adjusted and fixed through connecting rod 4, braced frame 3's below is provided with and steps on face 7, step on face 7 and weave cloth for the multilayer that possesses high bearing capacity. Firstly, the distance between the supporting frames 3 is adjusted to the maximum distance, then the tread surface 7 under the supporting frames 3 is unfolded (see fig. 5), and the multi-layer woven cloth bears the weight far exceeding the weight of the worker, so that the worker can be provided with a standing platform which is soft but far more stable than standing on a high-voltage wire.
The braced frame 3 still is connected with safety rope buckle 6, safety rope buckle 6 symmetry sets up two, and fixes respectively on upper left bracing piece 37 and upper right bracing piece 34. Safety rope buckle 6 is the indispensable structure of high altitude construction always, at first support frame 3's safety rope buckle 6 can articulate the tool bag, provide the transportation effect, in addition in for fixed with support frame 3 installation before, also need use safety rope buckle 6 to fix support frame 3 on transmission line 1, guarantee can not drop, and after fixed support frame 3, can fix the safety rope buckle 6 cooperation use on one's body of staff, secondly when 3 need remove under the carriage, can carry out manpower through the mode of hanging the rope on safety rope buckle 6 and drag etc. be very convenient.
The supporting frame 3 comprises a bottom supporting rod 39, a left lower supporting rod 38 and a right lower supporting rod 31 are connected to the two sides of the bottom supporting rod 39 in a rotating mode through a pin shaft, a left upper supporting rod 37 is connected to one end, far away from the bottom supporting rod 39, of the left lower supporting rod 38 in a rotating mode through a connecting seat 32, a right upper supporting rod 34 is connected to one end, far away from the bottom supporting rod 39, of the right lower supporting rod 31 in a rotating mode through the connecting seat 32, the left upper supporting rod 37 and the right upper supporting rod 34 are connected with the two ends of a push rod 35 in a rotating mode through the pin shaft respectively, the push rod 35 is divided into two sections and can be fixedly connected together. Because the device takes 6 high-voltage transmission lines 1 as an example, the hexagonal structure is most reliable and has strong activity, the device can be fixed only by fixing the mandril 35, and the rotation condition can not occur.
The ejector rod 35 comprises a first rod 353 and a second rod 351, the first rod 353 is connected with the left upper supporting rod 37, the second rod 351 is connected with the right upper supporting rod 34, hooks in opposite directions are arranged on the first rod 353 and the second rod 351 and can be connected together in a hanging mode, external threads are arranged on the outer walls of the first rod 353 and the second rod 351, and a fixing sleeve 352 with internal threads is sleeved and connected and can move at the external threads, so that the first rod 353 and the second rod 351 can be fixed.

Wherein the rotating sleeve 36 contacts the uppermost transmission line 1 and can keep the support frame 3 in sliding friction therewith. The friction force is reduced, so that the supporting frame 3 can slide on the power transmission line 1 more conveniently, the movable rotating sleeve 33 is used for keeping sliding friction with the middle power transmission line 1, the friction force is reduced in an auxiliary mode, the physical force of workers can be reduced in one step, and the conveying process is smoother.
The top including braced frame 3 is connected with fixed knot 5 through the round pin axle rotation, fixed knot 5 includes the couple portion 51 with braced frame 3 lug connection, be provided with screw thread section 52 on the couple portion 51, the lock catch 54 that the cooperation was used has been cup jointed on couple portion 51, lock catch 54 can move on couple portion 51, just the outside of lock catch 54 is provided with nut 53, nut 53 uses with screw thread section 52 cooperation, is used for fixing lock catch 54. The design of the fixing buckle 54 is that after the design of the rotating sleeve 36 is taken into consideration, the friction force of the supporting frame 3 is reduced, so that the constant distance between the two supporting frames 3 cannot be maintained, and therefore improvement is needed, the designed fixing buckle 5 can be directly fixed on the power transmission line 1, the supporting frame 3 is completely fixed, and cannot slide, the structure at the moment can become more stable, and a worker can feel more attentive when standing on the treading surface 7.
The fixing buckles 5 (shown in fig. 4) are respectively arranged on the left upper supporting rod 37 and the right upper supporting rod 34, and are arranged on the side far away from the safety rope buckle 6. The safety rope buckle 6 is far away from the ground, so that the safety rope buckle and the ground cannot interfere with each other to cause accidents such as knotting or incapability of rotating, and the like, and the mode with better stability is selected for high-altitude operation, so that physical power is not wasted on useless things as far as possible.
Connecting rod 4 passes through two braced frame 3 of connecting seat 32 connection, and connecting rod 4 sets up two, connecting rod 4 includes the connection piece 41 fixed with connecting seat 32, connection piece 41 rotates respectively and connects first connecting rod 42 and second connecting rod 44, the one end that connection piece 41 was kept away from to first connecting rod 42 and the one end that connection piece 41 was kept away from to second connecting rod 44 are connected through the round pin axle rotation, and first connecting rod 42 and second connecting rod 44 all are provided with the external screw thread to cup jointed connecting rod fixing sleeve 43, connecting rod fixing sleeve 43 can remove and fixed first connecting rod 42 and second connecting rod 44 make it unable rotation in external screw thread department. This structure can guarantee that two braced frame 3 are in the furthest distance to trampling face 7 at this moment reaches the maximum distance, thereby is expanded and is set level, and trampling face 7 at this moment can be more stable, and connecting rod 4 can guarantee that the device is after expanding, even do not fix through fixed knot 5, also can guarantee the constant distance between two braced frame 3, thereby accomplishes whole task, and can maintain this kind of state and remove. Two switched states of the link 4 can be understood with reference to the state switching of fig. 6 and 7.
As shown in fig. 1, which is the best working condition, the worker stands on the treading surface 7 and the two ends are the supporting frames 3, the push rod 35 can be used as the handrail, and the transmission line 1 and the transmission line can complete the rectangular frame to protect the worker, as shown in fig. 2, when the fixing buckle 5 works, the push rod 35 can be unfolded to facilitate the worker to come in and go out, without drilling or turning over the push rod 35, while fig. 3 is the conventional shape of the device, which can be pulled to move, and can hang tool bags and the like on the safety rope buckle 6, or other workers can pull the tool bags and the like to move through the rope.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or additions or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also included in the scope of the present invention.
