Description

Technical Field

[0001] The invention relates to the technical field of electric power construction, and in particular to an electric power construction work vehicle capable of changing the direction of equipment. Background Art

[0002] As the development direction of power transmission engineering technology, the focus is on studying ultra-high voltage (above 1 million volts) AC transmission and DC transmission technology to form a larger power network. The final application of electricity is inseparable from the vast transmission grid and various power facilities required by the grid. Therefore, in power engineering, the construction and inspection and maintenance of power equipment are also important parts of ensuring stable power transmission.

[0003] The infrastructure of the power system mainly includes power stations, substations and various types of transmission lines. The transmission circuit is mainly composed of cables and frames supporting cables. The transmission lines mainly include high-voltage transmission lines and distribution lines. Among them, the purpose of the distribution line is to transmit electric energy from the substation to the user, which is the last link in the power system.

[0004] For example, the basic power equipment of the distribution line cannot be separated from equipment such as utility poles and support frames. During the actual construction or maintenance work, it is necessary to straighten the utility poles or reinstall new utility poles and support frames and other power equipment in the corresponding positions when replacing them. At this time, the lifting equipment on the power construction work vehicle can be used to lift the power equipment first, and then move it to the designated position and lower it. However, it should be noted that during the actual installation process, it is necessary to ensure the accuracy of the position of the power equipment to ensure accurate installation. At this time, it is necessary to position and support the bottom of the power equipment. For example, use the clamping assembly (such as a forklift structure) provided on the power construction work vehicle to position the bottom of the power equipment, thereby facilitating the precise installation of the power equipment.

[0005] Since most of the existing electric poles are cylindrical cement pole structures, they only need to be buried in the designated position during actual installation. Therefore, the above-mentioned equipment can quickly and effectively install electric poles and other mechanical equipment such as support frames that only need to be buried. However, for some special locations, in order to increase the service life of electric poles or support frames, steel structures will also be used. Such structures cannot be directly buried in the soil, and pile foundations need to be cast in advance, and then they are installed on the pile foundations through structures such as bolts. Therefore, in the actual use of the electric construction work vehicle, the orientation of the installed electric equipment also needs to be considered to ensure that the electric equipment can accurately fit the pre-buried bolts. Therefore, based on the above-mentioned electric construction work vehicle, After the work vehicle uses the clamping assembly to fix the bottom of the facility, it is necessary to adjust the actual position and posture of the power construction work vehicle to adjust the actual angle of the installation facility. If there are other buildings or objects blocking the actual work site, or in order to effectively carry the replacement power equipment, the overall size of the power construction work vehicle is relatively large, it is not easy to adjust the posture of the power construction work vehicle, and then in the actual installation process, it will increase the difficulty of construction. If the clamping assembly is cancelled to fix the bottom of the facility, the danger of the installation process is increased, and the installation operation time is also increased, affecting the construction and maintenance efficiency of the distribution line, especially for power emergency repair construction, affecting the emergency repair speed. Summary of the invention

[0006] In order to enable the entire electric construction work vehicle to solve the orientation problem of the installed electric equipment, thereby eliminating the need to adjust the posture of the electric construction work vehicle, saving operation time and improving efficiency, the present application provides an electric construction work vehicle that can change the orientation of the equipment.

[0040] The following is combined with Figure 1-17 This application is described in further detail.

[0041] The embodiment of the present application discloses an electric power construction vehicle with a changeable equipment orientation, including an electric power construction vehicle 1, a cargo box 11 is provided on the electric power construction vehicle 1, a dispatching assembly 2, a clamping assembly 3 and an accessory box 4 are installed on the electric power construction vehicle 1 (the accessory box 4 is used to place common electric power construction tools), the dispatching assembly 2 includes a boom 21 and a lifting driver 22, a hook assembly 23 is provided at the end of the boom 21, the boom 21 is rotatably installed on the electric power construction vehicle 1, and the lifting driver 22 is arranged between the electric power construction vehicle 1 and the electric power construction vehicle 1, and is used to drive the boom 21 for lifting operations (wherein the lifting driver 22 includes a rotating driving structure for driving the boom 21 to rotate horizontally, a swinging driving structure for driving the boom 21 to swing up and down, a telescopic driving system for driving the boom 21 to telescope, and a cable winding mechanism for driving the hook assembly 23 to rise and fall, etc., and the above-mentioned equipment are all commonly used driving equipment for dispatching assemblies in the prior art, such as hydraulic cylinders, hydraulic systems and winches, etc., so this embodiment will not be explained in detail);

[0042] The clamping assembly 3 includes a driving frame 31 and a clamping jaw assembly 32. The clamping jaw assembly 32 includes a clamping seat 321 and a clamping arm 322. The clamping seat 321 can be flipped on the electric power construction work vehicle 1 through the driving frame 31, that is, the clamping jaw assembly 32 can be flipped up and down along the horizontal axis. The clamping arm 322 is arranged in two groups. The two groups of clamping arms 322 are movably mounted on the clamping seat 321, and the two groups of clamping arms 322 make a translational movement on the clamping seat 321 to move closer to or away from each other.

[0043] Furthermore, track assemblies 33 are provided on the upper and lower sides of each group of clamping seats 321, that is, the track assemblies 33 cooperate with the clamping arms 322 to form two groups on the left and right, and each group of clamping arms 322 includes two upper and lower groups, for a total of four groups of tracks 333 (the track assemblies 33 mentioned in this embodiment are at least two in the upper and lower directions, and three, four or even more groups can also be provided). The track assembly 33 includes a track frame 331 and a track 333. The track frame 331 is provided with multiple groups of track wheels 332, and the track 333 is mounted outside the track wheels 332. A clamping working surface is formed on the side close to the track 333 on the two groups of clamping arms 322, and one group of track wheels 332 is a driving wheel for driving the track assembly 33 to move. In this embodiment, the four track assemblies 33 are independently controlled and can be freely adjusted according to actual usage conditions. As for the drive control of the track assembly 33, it is an existing solution for controlling track products in the prior art. Therefore, this embodiment will not be explained in detail.

[0044] It should be noted that the technology of the clamping jaw assembly 32 can refer to the mechanical clamping jaw structure, and it only needs to be able to control the two groups of clamping arms 322 to move closer or farther away from each other. Simply, the two groups of clamping arms 322 can be slidably installed on the clamping base 321, and clamping drivers (such as hydraulic cylinders) are provided on the clamping base 321 to drive the two groups of clamping arms 322 to move horizontally, so as to realize the clamping control of the clamping arms 322. At the same time, the method described in the appendix of the specification of the present invention can also be adopted. Figure 6 As shown in the figure, two parallel connecting rods can be used to connect the clamp arm 322 and the clamp seat 321 to form a parallelogram structure, and a rotation driver (such as a motor) is provided to drive one of the connecting rods to swing. By driving one of the connecting rods to swing, the clamp arm 322 can be driven to produce translational motion. This scheme is a commonly used connection and drive scheme in mechanical clamps, and will not be explained in detail in this embodiment.

[0045] By adopting the above technical solution, in actual use, the electric power construction work vehicle 1 can be used to carry many electric power construction tools, and the cargo box 11 can be used to transport and load some of the facilities to be installed 5. For example, one or more electric poles can be placed in the cargo box 11 for transportation (this embodiment is mainly explained with the transportation and installation of electric poles. Therefore, the facilities to be installed 5 proposed in this embodiment refer to electric poles unless otherwise specified). After the facilities to be installed 5 are transported to the corresponding place, the posture of the electric power construction work vehicle 1 is adjusted to fix it near the construction and installation site, and then the electric pole can be lifted with the help of the transportation component 2. At this time, referring to the attached figure of the specification, the two sets of clamping arms 322 can be controlled to approach each other to align the electric poles. The bottom end of the pole is clamped, and at the same time, the top of the pole is grasped and lifted with the help of the transportation component 2, and the pole is gradually verticalized by cooperating with the flip control of the clamping claw component 32. For cement poles that can be directly buried in the pit, after adjusting the posture of the pole, the clamping claw component 32 directly releases the pole and then lowers it. However, for some steel poles that cannot be directly pre-buried and need to be installed on the installation pile foundation 51 or other types of facilities to be installed 5 (such as equipment brackets and small distribution boxes, etc.), in the actual installation process, it is necessary to make specific adjustments to the bottom position of the installation facility 5, which involves fine adjustments such as swinging, moving and rotating the installation facility 5. The technical solution provided in this embodiment is adopted, and reference is made to the attached manual. Figure 8 When the clamping working surfaces of the upper and lower crawlers 333 on each set of clamping arms 322 move synchronously in opposite directions (the left and right crawler assemblies 33 need to be synchronized, that is, the clamping working surfaces of the left and right crawler assemblies 333 are relatively adapted in the same direction), the facility 5 to be installed can be driven to swing. When the clamping working surfaces of the crawler assemblies 33 on the left and right crawler arms 322 move synchronously in the same direction (because the two sets of crawler assemblies 33 are symmetrically arranged, when the clamping working surfaces move in the same direction, the two sets of crawlers 333 actually rotate in opposite directions, and vice versa), when clamping the facility 5 to be installed, refer to the attached manual. Figure 7 , can drive the installation 5 to move horizontally, and then adjust the bottom movement of the installation 5, and when the clamping working surfaces of the left and right crawler assemblies 33 move in the opposite direction, refer to the attached manual Figure 7 , which can drive the facility to be installed 5 to rotate, so that the facility to be installed 5 with the installation hole can be accurately connected with the bolt structure on the installation pile foundation 51 during installation, thereby improving the installation efficiency and reducing the construction difficulty, especially for power emergency repair construction, which can further reduce the construction time and improve the emergency repair speed. The power construction work vehicle 1 provided in this embodiment has diverse functions, simple operation, high practicality, and can adapt to more construction scenarios.

[0046] In the above embodiment, the driving frame 31 includes a transverse guide rail 311, a transverse frame 312, a lifting frame 313 and a turning frame 314. The transverse guide rail 311 is fixedly installed on the electric construction work vehicle 1, the transverse frame 312 is laterally slidably installed on the transverse guide rail 311, and a transverse drive such as a hydraulic cylinder is arranged between the transverse guide rail 311 and the transverse frame 312 for driving the transverse movement of the transverse frame 312, and the lifting frame 313 is vertically slidably installed on the transverse frame 312, and a lifting drive such as a hydraulic cylinder is arranged between the lifting frame 313 and the transverse frame 312 for driving the lifting frame 313 to move vertically. Hydraulic cylinder, the flip frame 314 is rotatably installed on the lifting frame 313, and a flip driver (such as a rotatably connected flip driving hydraulic cylinder) for driving the flip frame 314 to flip is arranged between the flip frame 314 and the lifting frame 313, and the clamp seat 321 is fixedly installed on the flip frame 314. In addition to being able to adjust the installation facility 5 with the help of the crawler assembly 33, after the electric construction work vehicle 1 stops, the driving frame 31 can drive the clamp assembly 32 to generate lateral movement, lifting and flipping and other movements, thereby further improving the diversity of driving the installation facility 5 and increasing the functionality of the equipment.

[0047] It should be noted that, in addition to assisting the installation of new utility poles, the above-mentioned equipment can also straighten tilted collapsed utility poles, and has strong functionality. At the same time, in addition to cylindrical utility poles, the facilities to be installed 5 also include some non-cylindrical polygonal column structures, such as multi-cornered columns, multi-cornered frames, and rectangular distribution boxes. Such polygonal facilities to be installed 5 have edge structures, and the fewer the edges, the sharper the edge structures. Although the equipment itself will provide rounded or chamfered structures at the edges, the above-mentioned implementation method is prone to slipping when facing the edges of such facilities to be installed 5, and unlike the cylindrical structure, the outer wall position of the polygonal facilities to be installed 5 will change when rotating. Therefore, in order to make the crawler 333 better adapt and fit the edges of the facilities to be installed 5 and drive them effectively, the present embodiment also provides the following technical solutions. For details, refer to the attached manual. Fig. 9 An elastic frame 34 is provided on the track frame 331, and an auxiliary wheel 341 is provided at the position of the elastic frame 34 corresponding to the clamping working surface. The auxiliary wheel 341 rolls and fits with the inner wall of the track 333 to form an auxiliary support for the track 333, and one end of the elastic frame 34 corresponding to the auxiliary wheel 341 has an elastic force approaching the clamping working surface of the track assembly 33, so that the position of the track 333 corresponding to the clamping working surface can have an inwardly concave elastic force. When clamping the facility 5 to be installed, it can be concave according to the situation to increase the fitting effect with the facility 5 to be installed, and improve the clamping stability and operating stability.

[0048] The two ends of the balancing frame 342 are rotatably mounted on the auxiliary wheels 341, thereby increasing the support range of the auxiliary wheels 341 and improving the support effect of the auxiliary wheels 341 on the auxiliary wheels 341.

[0049] Furthermore, in the process of the crawler 333 clamping working surface moving to drive the installation 5 to be installed to move or rotate, if the crawler 333 is only a plane structure, when facing the edge of the installation 5, the actual contact is relatively small, and when the crawler 333 moves, the carrying capacity of the installation 5 to be installed is also weakened, affecting the adjustment efficiency. For this reason, refer to the attached manual. Fig.10 The present embodiment also provides the following technical solution: the surface of the crawler 333 is provided with an elastic support structure 35, the elastic support structure 35 includes an inner nest 351 and a slide post 352, the inner nest 351 is embedded and installed in the crawler 333, the slide post 352 is slidably installed in the inner nest 351, and a first elastic member 353 is provided between the slide post 352 and the inner nest 351, the first elastic member 353 provides an outward elastic force (such as a spring) to the inner nest 351, and a contact protection member 36 is installed on the outside of the slide post 352, so that it can be in contact with the facility to be installed 5 When the crawler 333 moves on the surface of the facility 5 to be installed, it can better adapt to the shape of the surface of the facility 5 to be installed. For example, when the track 333 encounters the edge of the facility 5 to be installed, the sliding column 352 closest to the edge of the facility 5 to be installed is compressed, but the remaining parts are affected by the shape of the facility 5 to be installed, and some parts will not be compressed and will contact the two side parts of the edge of the facility 5 to be installed in the form of a convexity. Then, when the crawler 333 moves, the sliding columns 352 on both sides of the edge of the facility 5 to be installed can generate a certain thrust for the facility 5 to be installed, thereby improving the driving effect of the facility 5 to be installed.

[0050] Furthermore, the contact protection member 36 as the intermediate structure between the installation 5 and the slide column 352 can be a flexible structure or an elastic structure, which can provide a certain buffer to protect the surface of the installation 5. Therefore, the contact protection member 36 can be a point contact member 361, and one point contact member 361 corresponds to a group of elastic support structures 35. The point contact member 361 is fixedly installed on the slide column 352. Fig.11 The point contact members 361 are distributed in a rectangular array on the track assembly 33, thereby improving the adaptation effect of the elastic support structure 35 and providing more adaptability space.

[0051] In addition, refer to the instructions attached Fig.12 The contact protection member 36 can also be a strip contact member 362, which is vertically distributed on the track 333, and multiple strip contact members 362 are evenly distributed on the track 333. One strip contact member 362 corresponds to multiple elastic support structures 35, and multiple elastic support structures 35 are arranged along the length direction of the strip contact member 362, that is, multiple sliding columns 352 are fixedly connected to one strip contact member 362, thereby improving the support strength of the strip contact member 362 and improving the support effect.

[0052] It should be noted that when the above embodiment is adopted, if the equipment needs to swing and adjust the multi-faceted installation facility 5, refer to the attached manual. Fig.13 If the edge of the facility 5 to be installed is relatively sharp, when the crawler 333 moves relative to the facility 5 to be installed and causes the facility 5 to swing, the facility 5 to be installed will swing with the contact protection member 36 on the crawler 333. At this time, if a simple point contact member 361 or strip contact member 362 structure is used, a large friction is easily formed between the swing of the facility 5 to be installed and the contact protection member 36, which is easy to cause damage to the protective paint layer on the surface of the facility 5 to be installed. Therefore, this embodiment also provides the following technical solutions, specifically, refer to the attached manual Figures 14 to 17The contact protection member 36 is a rope-type contact member 363, and the rope-type contact members 363 are provided in plurality, and the plurality of rope-type contact members 363 are evenly distributed on the crawler 333, and the rope-type contact members 363 are vertically provided on the crawler 333, and one rope-type contact member 363 corresponds to two sets of elastic support structures 35, wherein the rope-type contact member 363 corresponds to the crawler 333 and the inner nest 351 in the elastic support structure 35 at one end of the other set of crawlers 333 on the clamping arm 322 where the crawler 333 is located, and is fixedly installed in the crawler 333, and a guide member 37 is fixedly installed at the position of the other end of the crawler 333 corresponding to the rope-type contact member 363, and the inner nest 351 at the corresponding guide member 37 is vertically slidably installed in the guide member 37, and a second elastic member 371 (such as a spring) is provided in the guide member 37 for providing a vertical elastic force to the inner nest 351 in the guide member 37, and the two ends of the rope-type contact member 363 are respectively fixedly connected to the two sliding posts 352;

[0053] It should be noted that, in the two corresponding contact protection members 36 in the upper and lower track assemblies 33, the inner nest 351 at one end close to each other is relatively fixed to the track 333. For example, the inner nest 351 at the bottom end of the rope contact member 363 located at the top is fixedly connected to the group of tracks 333, and the inner nest 351 at the top end of the rope contact member 363 located at the bottom is fixedly connected to the group of tracks 333. The other ends of both can produce vertical sliding. Therefore, in actual use, when the track 333 initially contacts the inclined facility 5 to be installed, if the rope contact member 363 contacts the edge of the facility 5 to be installed, the rope contact member 363 will be squeezed and produce a twisted configuration adapted to the inclined edge of the facility 5 to be installed. Please refer to the attached manual for details. Fig.17 The rope contact piece 363 produces a certain degree of twisting, and its movable end can be pulled and moved to adapt to the edge of the facility to be installed 5. Therefore, when the deflection of the facility to be installed 5 is subsequently adjusted, the rope contact piece 363 can produce adaptive recovery or continue to twist deformation, reducing the relative displacement and friction loss with the surface of the facility to be installed 5, and further improving the safety and practicality of the equipment.

[0054] It should be noted that the above three solutions of the contact protection member 36 can be used in combination with each other and are not limited to being used alone.
