The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
Referring to fig. 1 to 10, an embodiment of the present invention provides an electric pole anti-collision device, which includes a force transmission cylinder 100, a clasping assembly 200 connected to an inner side of the force transmission cylinder 100 and adapted to clasp an electric pole, and a force unloading cylinder 300 connected to an outer side of the force transmission cylinder 100 and adapted to bear collision impact.
The force transmission barrel 100 is of a cylindrical structure with a through upper part and a through lower part, an annular fixing position 101 is arranged on the outer side wall of the force transmission barrel, and a plurality of groups of upper hinge positions 102 and lower hinge positions 103 which are distributed along the circumferential direction and are in one-to-one correspondence are arranged on the inner side wall of the force transmission barrel. The upper hinge joint 102 and the lower hinge joint 103 have the same structure and are arranged vertically and symmetrically and are used for connecting the clasping component 200; each lower hinge point 103 is located directly below its corresponding upper hinge point 102.

The upper connecting rod group 201 and the lower connecting rod group 202 have the same structure and are arranged in a vertically symmetrical manner, and both can adopt a multi-group connecting rod structure.
The upper clasping blocks 203 correspond to the lower clasping blocks 204 one by one, tensioning pieces 205 are further connected between each upper clasping block 203 and the corresponding lower clasping block 204, the tensioning pieces 205 can be stretched and pressed on the outer side wall of the electric pole, and a first interlayer space K-1 is formed between the force transmission cylinder 100 and the outer side wall of the electric pole.
After each upper clasping block 203 and the corresponding lower clasping block 204 are tightened by the tightening piece 205, the vertical distance between the upper clasping block 203 and the lower clasping block 204 is greater than the vertical distance between the upper hinge 102 and the lower hinge 103, so that the upper connecting rod set 201 and the lower connecting rod set 202 of each set of clasping assembly 200 can be in a splayed shape to stably press and support the outer side wall of the electric pole, and the periphery of the electric pole is clasped by each clasping block, thereby realizing the fixation of the whole device on the electric pole.
Force-releasing cylinder 300 is located on the periphery of force-transmitting cylinder 100 and comprises a support layer 301 connected to annular fixing position 101 and a buffer layer 302 arranged on the outer layer of support layer 301. The support layer 301 plays a role of a bracket and is used for installing and fixing the buffer layer 302; the cushioning layer 302 is made of an elastic material (such as rubber) and serves as a cushion pad and can protect the outside.
When foreign objects impact on the force-removing cylinder 300, the buffer layer 302 can be elastically deformed, so that the buffer effect can be achieved, and damage to the electric pole is reduced.
Further, the force-discharging cylinder 300 is connected to the annular fixing station 101 through the rotating assembly 400, and can perform a relative horizontal rotating motion.
The rotating assembly 400 comprises a rotating ring 401 which is sleeved on the annular fixing position 101 and can rotate relatively, and a plurality of connecting pieces 402 which are uniformly distributed and fixed on the outer edge of the rotating ring 401 along the circumferential direction; the end of each connecting piece 402 is attached to the inner side wall of the supporting layer 301 by the first connecting piece 403, so that a second interlayer space K-2 exists between the inner side wall of the supporting layer 301 and the outer side wall of the force transmission cylinder 100.
The rotating ring 401 is of an annular structure with a cross section matched with the annular fixing position 101, and the first connecting piece 403 can be a bolt to realize detachable connection between the connecting piece 402 and the supporting layer 301.
The connecting piece 402 includes a deformation section 402a, and a first connecting end 402b and a second connecting end 402c respectively located at two ends of the deformation section 402 a. The first connecting end 402b is fixed to the inner side wall of the support layer 301 by a first connector 403, and the second connecting end 402c is fixed to the outer edge of the rotating ring 401 by a second connector 404. The deformation section 402a is a bent plate structure, which can be deformed laterally; the first end 402b is located below the second end 402c and is further away from the force transfer cylinder 100 than the second end 402 c. The whole connecting sheet 402 can be made of a steel plate with low carbon content, has elastic deformation capacity and strong toughness, and is convenient for bearing adaptive deformation after impact and recovery after force unloading.
When a foreign object impacts on the force-releasing cylinder 300, on one hand, the buffer layer 302 can perform a buffering function because of elastic deformation; on the other hand, the connecting piece 402 can also be deformed in a lateral direction, so that a part of impact can be buffered; in addition, because the force-discharging cylinder 300 is rotatably connected to the annular fixed position 101 through the rotating assembly 400 and can rotate, a part of impact force can be avoided, and when the impact direction of a foreign object is not right opposite to the axis of the force-discharging cylinder 300, the force-discharging cylinder 300 can discharge force through self rotation, change the impact direction of the impacting object, and resolve the impact force.
Preferably, the annular fixing portion 101 includes an annular step surface 101a and an annular groove bottom surface 101b, which are connected to each other to form an inner side wall of the annular fixing portion 101.
The step surface 101a and the groove bottom surface 101b are respectively provided with an annular rolling track 101c, and the rotating ring 401 is provided with a corresponding matching track 401 a. When the rotating ring 401 is embedded into the annular fixing portion 101, the matching track 401a and the rolling track 101c can form an annular ball track Z in a surrounding manner, and a plurality of steel balls 405 are arranged in the ball track Z, so that the rotating lubrication degree of the rotating ring 401 in the annular fixing portion 101 is improved, the friction is reduced, and the impact is better solved through the rotation of the rotating ring 401.
Further, the rotating assembly 400 further includes a plurality of limiting insertion plates 406 fixed to the outer sidewall of the force transmission cylinder 100. The other side of the rotating ring 401 relative to the direction of the step surface 101a is also provided with an annular slot 401b corresponding to the limiting insert plate 406, and the tail end of each limiting insert plate 406 is inserted into the annular slot 401b to limit the relative rotation of the rotating ring 401 and further guide the relative rotation.
Further, the force-discharging cylinder 300 is rotatably connected to the force-transmitting cylinder 100 through a pair of rotating assemblies 400, and the force-transmitting cylinder 100 is provided with a corresponding pair of annular fixing locations 101. Each rotating assembly 400 is arranged on the corresponding annular fixing position 101, and the rotating ring 401 of each group of rotating assemblies 400 is fixedly connected with the inner side wall of the supporting layer 301 through a plurality of connecting pieces 402 distributed on the circumference of the rotating ring. The stability of the connection of the force-releasing cylinder 300 to the force-transmitting cylinder 100 is improved.
Further, the upper link set 201 and the lower link set 202 are symmetrically disposed, and both of them respectively include a pair of links parallel to each other and arranged up and down. Of course, the upper linkage 201 (or the lower linkage 202) may further include 2 pairs of links arranged in parallel and up and down, so as to improve the strength and pressure-bearing capacity of the structure.
One end of each connecting rod in the upper connecting rod group 201 is hinged with the upper hinge position 102, and the other end is hinged with the upper enclasping block 203.
One end of each link in the lower linkage 202 is hinged to the lower hinge point 103, and the other end is hinged to the lower hugging block 204.
Preferably, the upper hinge 102 and the lower hinge 103 may be vertical strip-shaped grooves on the inner sidewall of the force-transmitting cylinder 100, and the outer ends of the respective connecting rods can be embedded into the strip-shaped grooves and are hinged by a rotating shaft. In addition, the upper holding block 203 and the lower holding block 204 are also provided with vertical strip-shaped grooves corresponding to the inner ends of the connecting rods, and the inner ends of the connecting rods can be embedded into the strip-shaped grooves and are hinged through rotating shafts.
Further, the tension member 205 has elasticity and can be elongated and restored by tension, and a strong metal tension spring, an elastic rubber rope, or the like can be used.
Further, in another embodiment, a vertically through first channel 203a is arranged inside the upper holding block 203, and a first caulking groove 203b is arranged at one end of the first channel 203a far away from the lower holding block 204; the inner diameter of the first caulking groove 203b is larger than that of the first passage 203 a.
The lower holding block 204 and the upper holding block 203 are the same in structure and are symmetrically arranged. Correspondingly, a vertically through second channel 204a is arranged in the lower clasping block 204, and a second caulking groove 204b is arranged at one end of the second channel 204a far away from the upper clasping block 203; the inner diameter of the second caulking groove 204b is larger than the inner diameter of the second passage 204 a.
The tension member 205 includes an elastic cable 205a capable of passing through the first and second passages 203a and 204a, a first locking member 205b capable of being fitted into the first fitting groove 203b, and a second locking member 205c capable of being fitted into the second fitting groove 204 b. The inner diameters of the first passage 203a and the second passage 204a are not smaller than the cross-sectional outer diameter of the elastic cord 205 a.
The first locking piece 205b and the second locking piece 205c are symmetrically arranged and have the same structure, and both of the first locking piece 205b and the second locking piece 205c comprise a lantern ring S-1 and a plurality of latch teeth S-2 which are distributed on the outer end face of the lantern ring S-1 along the circumferential direction and extend outwards vertically. The outer diameter of the collar S-1 is fitted to the inner diameter of the first caulking groove 203b or the second caulking groove 204 b.
The interior of the lantern ring S-1 is provided with a through hole S-11 which is through up and down, and the inner diameter of the through hole S-11 is larger than the outer diameter of the cross section of the elastic pull rope 205 a. The tail end of each latch S-2 forms a tip and slantwise folds towards the axis direction of the lantern ring S-1, and the tips together enclose a bayonet K with the inner diameter not larger than the outer diameter of the elastic inhaul cable 205 a.
Therefore, for the elastic cable 205a passing through the through hole S-11, when the direction of the pulling force applied to the elastic cable 205a is opposite to the extending direction of the latch S-2, the tip of the latch S-2 can partially press into the outer skin of the elastic cable 205a, and the locking function of the barb is realized, and the elastic cable 205a is prevented from being separated from the latch S-2. On the contrary, when the direction of the pulling force applied to the elastic cable 205a is the same as the extending direction of the latch S-2, the elastic cable 205a can smoothly slide in the through hole S-11, and the latch S-2 does not have a locking function of the "barb". Therefore, when the end of the elastic cable 205a needs to be threaded into the first locking member 205b or the second locking member 205c, the threading direction needs to be the same as the protruding direction of the latch S-2 of the first locking member 205b or the second locking member 205 c. The elastic cord 205a in the present embodiment is preferably an elastic rubber cord having high strength.
In the invention, after the upper clasping block 203 and the corresponding lower clasping block 204 are tightened by the tightening piece 205, the first locking piece 205b is embedded into the first embedding groove 203b, and the extending direction of the latch S-2 is upward; the second locking piece 205c is inserted into the second slot 204b, and the extending direction of the latch S-2 is downward; both ends of the elastic cable 205a are respectively exposed out of the first locking piece 205b and the second locking piece 205c, and a section between the first locking piece 205b and the second locking piece 205c is in a stretched state.
When a foreign object impacts on the force-unloading cylinder 300 along a certain direction, the electric pole anti-collision device of the invention has four times of buffering or force-unloading processes:
firstly, the buffer layer 302 can perform a buffering function because of elastic deformation;
secondly, the connecting piece 402 can be deformed in a lateral direction, and a part of impact can be buffered (the connecting piece 402 near the impact direction can be laterally extruded; the connecting piece 402 far away from the impact direction can be laterally stretched; the connecting piece 402 in the middle area has corresponding deformation or a self rotation adapting process);
thirdly, as the force unloading cylinder 300 is rotatably connected to the annular fixing position 101 through the rotating assembly 400 and can rotate, the force unloading cylinder 300 can unload force through rotation of itself, change the impact direction of an impacting object and change the impact force;
fourth, the force-releasing cylinder 300 and the force-transmitting cylinder 100 are eccentric (move horizontally in the direction of impact) relative to the pole under the impact of foreign objects. The opening of the upper link group 201 and the lower link group 202 corresponding to the vicinity of the impact direction is larger, and the corresponding tension member 205 is elongated, and the width of the first interlayer space K-1 at the corresponding position is reduced; the upper connecting rod set 201 and the lower connecting rod set 202 far away from the impact direction have smaller openings due to the shortening of the tension piece 205, the width of the first interlayer space K-1 at the corresponding position is increased, and the corresponding holding block still presses the surface of the electric pole in a adaptability manner; the intermediate band clasping assembly 200 has a corresponding mouth opening size and horizontal offset process. The eccentricity of the force-releasing cylinder 300 and the force-transmitting cylinder 100 relative to the electric pole is based on the opening change of the upper linkage 201 and the lower linkage 202 and the elastic tension of the elastic cable 205a, so that the excellent buffering effect can be achieved.
Further, the upper clasping block 203 is provided with a first slit 203c communicated to the first channel 203a, and the width of the first slit 203c corresponds to the outer diameter of the elastic cable 205a and is smaller than the inner diameter of the first channel 203 a. Meanwhile, the lower hugging block 204 is provided with a second slit 204c communicated to the second channel 204a, and the width of the second slit 204c corresponds to the outer diameter of the elastic cable 205a and is smaller than the inner diameter of the second channel 204 a. Therefore, the installation and fixation of the tension piece 205 between the lower enclasping block 204 and the upper enclasping block 203 are facilitated, and the specific installation steps are as follows:
firstly, the upper end of the elastic cable 205a penetrates out of the bottom of the first locking piece 205b, and the penetrating direction of the upper end of the elastic cable 205a is consistent with the extending direction of the latch S-2 of the first locking piece 205 b;
secondly, stretching the lower end of the elastic cable 205a, embedding the middle section of the elastic cable 205a into the first channel 203a and the second channel 204a from the first slit 203c and the second slit 204c respectively, and releasing the first locking member 205b, so that the first locking member 205b is embedded into the first embedding groove 203 b;
thirdly, the lower end of the elastic cable 205a penetrates out of the top of the second locking piece 205c, and the penetrating direction of the lower end of the elastic cable 205a is consistent with the extending direction of the latch S-2 of the second locking piece 205 c; then, the second locking piece 205c is released, so that the second locking piece 205c is fitted into the second fitting groove 204 b.
The tension member 205 can be quickly and conveniently installed through the above process.
