[0002] The transformer is the core equipment of the power system, which provides stable voltage conversion and ensures the normal operation of electrical equipment, lighting equipment, communication base station, medical equipment, etc. However, in the rugged terrain and road impassable mountain environment, the installation of the transformer faces great difficulties. Due to the rugged mountain road, the transport vehicle cannot reach directly, and the equipment needs to be carried on the shoulder by the workers. When the existing transformer is carried uphill, due to the large weight of the transformer, it cannot be moved for a long time by the workers carrying, and the cooperation of multiple workers carrying is difficult due to the rugged mountain road, the carrying efficiency is poor, and the transformer is unevenly stressed when carrying, which is prone to side turning and produces safety hazards. SUMMARY

[0003] In order to overcome the shortcomings that the workers carrying efficiency is low due to the large weight of the transformer and the rugged mountain road, and the transformer is prone to side turning when carrying and produces safety hazards, the present application provides a high-strength support for transformer field installation.

[0010] More preferably, it further comprises a limiting assembly, which comprises a threaded rod, a screw ring and a connecting cylinder; the threaded rod is connected to the underside of all the mounting beams; one screw ring is connected to each end of the threaded rod; one connecting cylinder is rotatably connected to each screw ring; and the end of the connecting cylinder away from the screw ring is fixedly connected to a pressing block.

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention. Example 1

[0029] like Figures 1-7 As shown, a high-strength support for on-site installation of a transformer includes two mounting beams 1;

[0030] It also includes connecting block 2, beam 3, round clamp 4, each mounting beam 1 lower side is slidably connected with two connecting blocks 2, each mounting beam 1 is provided with at least four limiting grooves 11, each connecting block 2 is inserted with one limiting plug 21, limiting plug 21 and limiting groove 11 are matched in size, left and right two connecting blocks 2 are rotatably connected with one beam 3, the both ends of beam 3 are inserted with one arc beam 31, arc beam 31 is a quarter of a circle, front and rear two arc beams 31 are commonly connected with one round clamp 4, mounting beam 1, connecting block 2, beam 3, arc beam 31 and round clamp 4 are made of high-strength alloy steel, to ensure that the support bears strength, and ensure that the transformer is installed stably.

[0031] The edge of the limiting plug 21 insertion end is provided with an inclined angle, which facilitates the insertion of the limiting plug 21 into the limiting groove 11.

[0032] The connecting block 2 is L-shaped, which limits the rotation angle of the beam 3 to ninety degrees, avoiding the need for workers to frequently adjust the rotation angle of the beam 3.

[0033] The surface of the beam 3 in contact with the ground is smooth, reducing the friction of the support moving on the ground in the form of a sled.

[0034] It also includes a square clamp 101, and a square clamp 101 is installed at the connection between the beam 3 and each arc beam 31, to increase the connection stability of the beam 3 and the arc beam 31.

[0035] The use steps of the high-strength support for transformer field installation are as follows:

[0036] The initial state of the support is shown in Figure 2 When the transformer needs to be transported, the beam 3 of the support is turned down by ninety degrees from the side away from the connecting block 2, so that the support changes into the sled state shown in Figure 3 At this time, the arc beam 31 on the beam 3 faces upwards, then the worker pulls out the limiting plug 21, and pulls the two connecting blocks 2 away from each other until the connecting block 2 moves to the edge of the mounting beam 1, the worker reinserts the limiting plug 21 into the corresponding limiting groove 11 of the mounting beam 1, then the worker installs the transformer on the mounting beam 1 of the support and fixes it through bolts and other connecting pieces, then the worker binds the rope on the support and the transformer, and pulls the sled-shaped support to drive the transformer to move towards the power pole in the mountain.

[0037] When the support and the transformer move to the power pole, the worker moves the support and the transformer obliquely between the two wires, and then adjusts the support to Figure 5As shown, the two cross beams 3 and the two poles are parallel to each other, and the two poles are located between the two cross beams 3. Then, the workers climb the poles, install a manual hoist for lifting the transformer on the poles, connect the lifting rope of the manual hoist with the transformer, operate the manual hoist to lift the transformer upward, and then stop the lifting. The workers on the ground rotate the cross beams 3 upward, and the two cross beams 3 return to the initial state, i.e., the two arc-shaped beams 31 of the two cross beams 3 are opposite to each other. At this time, the two poles are located in the enclosure formed by the cross beams 3 and the arc-shaped beams 31. Then, the workers pull out the limiting blocks 21, unlock the connecting blocks 2 and the installation beams 1, and push the two cross beams 3 to be close to each other, so that the arc-shaped beams 31 of the two cross beams 3 are in contact with each other, as shown in Figure 2 and Figure 6 As shown, the two cross beams 3 and the two poles are parallel to each other, and the two poles are located between the two cross beams 3. Then, the workers climb the poles, install a manual hoist for lifting the transformer on the poles, connect the lifting rope of the manual hoist with the transformer, operate the manual hoist to lift the transformer upward, and then stop the lifting. The workers on the ground rotate the cross beams 3 upward, and the two cross beams 3 return to the initial state, i.e., the two arc-shaped beams 31 of the two cross beams 3 are opposite to each other. At this time, the two poles are located in the enclosure formed by the cross beams 3 and the arc-shaped beams 31. Then, the workers pull out the limiting blocks 21, unlock the connecting blocks 2 and the installation beams 1, and push the two cross beams 3 to be close to each other, so that the arc-shaped beams 31 of the two cross beams 3 are in contact with each other, as shown in Figure 1 As shown, the two cross beams 3 and the two poles are parallel to each other, and the two poles are located between the two cross beams 3. Then, the workers climb the poles, install a manual hoist for lifting the transformer on the poles, connect the lifting rope of the manual hoist with the transformer, operate the manual hoist to lift the transformer upward, and then stop the lifting. The workers on the ground rotate the cross beams 3 upward, and the two cross beams 3 return to the initial state, i.e., the two arc-shaped beams 31 of the two cross beams 3 are opposite to each other. At this time, the two poles are located in the enclosure formed by the cross beams 3 and the arc-shaped beams 31. Then, the workers pull out the limiting blocks 21, unlock the connecting blocks 2 and the installation beams 1, and push the two cross beams 3 to be close to each other, so that the arc-shaped beams 31 of the two cross beams 3 are in contact with each other, as shown in

[0038] When the support is installed on the poles, the workers pull the arc-shaped beams 31 to increase the overall length of the cross beams 3, so as to adapt to the spacing between different poles (usually, the spacing between two adjacent poles is 2.2-2.5 m, and in the initial state, as shown in Figure 2 the overall length of the cross beams 3 and the arc-shaped beams 31 is 2 m).

[0039] The following describes the installation process of the transformer in the scenario where the poles are located on a slope:

[0040] When the support transports the transformer on the slope, the arc-shaped beams 31 are directed to the direction of travel. At this time, the support and the transformer are moved to the poles, and the support is in the state shown in Figure 7 The direction of travel is perpendicular to the connecting line of the centers of the two poles. Then, the manual hoist installed on the poles lifts the support off the ground, and then the support is rotated by 90 degrees (at this time, the cross beams 3 and the arc-shaped beams 31 are in the initial state, and the overall length is less than the spacing between the two poles). After the support is transversely arranged between the two poles, the arc-shaped beams 31 are pulled out of the cross beams 3, so that the overall length of the cross beams 3 and the arc-shaped beams 31 is longer than the spacing between the two poles, as shown in Figure 5As shown, two electric poles are located between the cross beams 3 and the arc-shaped beams 31 on both sides, then the two cross beams 3 are turned up to the installation state, the connecting blocks 2 are unlocked, the two cross beams 3 are pushed to be close to each other to form a closed enclosure, the connecting blocks 2 are locked again, finally the support is lifted to the installation position through the manual hoist, a circular clamp 4 is installed at the corresponding position below the arc-shaped beam 31 on each electric pole, and the circular clamp 4 is connected with the arc-shaped beam 31, and the installation of the transformer is completed.

[0041] According to the above steps, the present application has the following effects:

[0042] For the installation of transformers in mountainous areas, transportation vehicles cannot be used for transportation, and workers can only carry the transformers by hand. In this case, the support is transformed into a sled shape to carry the transformer for transportation, which is convenient for workers to transport the transformer and carry the support. Workers do not need to carry the transformer by hand, which improves the transportation efficiency and reduces the safety hidden danger. In addition, the support is used for installing the transformer, which is also used for transporting the transformer, without the need to use additional transportation devices, thereby reducing the cost. Moreover, the transformer and the support are installed at the same time, which optimizes the installation steps.

[0043] When the support is installed on the electric pole, the spacing between electric poles of different specifications is different, and the cross beams 3 and the arc-shaped beams 31 are arranged in a plug-in form. For the actual installation spacing of the electric poles, the arc-shaped beams 31 can be pulled out from the cross beams 3, and the overall length of the cross beams 3 and the arc-shaped beams 31 can be adjusted on site to adapt to the installation spacing between different electric poles. The adaptability is high, and the support can be adjusted flexibly according to the actual situation, and the practicality is strong.

[0044] When the electric pole is located on a slope, the support transports the transformer on the slope with the arc-shaped beam 31 facing the direction of travel. At this time, the support moves on the slope in the length direction, which has good support stability. After the support moves to the electric pole, the support needs to be turned to adapt to the arrangement direction of the two electric poles for installation, such as Figure 5 As shown, the arrangement direction of the cross beams 3 and the two electric poles is parallel. During this process, the placement form of the support on the slope changes from the length direction of the cross beams 3 and the arc-shaped beams 31 to the width direction, and the support force bearing surface on the slope changes, which leads to the decrease of the support stability of the support on the slope, and the support is prone to side overturning on the slope. Therefore, when the support and the transformer are installed on the slope, the cross beams 3 and the arc-shaped beams 31 with an initial length shorter than the spacing between the two electric poles are moved between the two electric poles, the support is lifted off the ground through the manual hoist, the manual hoist is kept stable, and then the turning operation is performed. Avoiding that the support surface changes from the length direction of the cross beams 3 and the arc-shaped beams 31 to the width direction when the support is turned on the ground supported by the cross beams 3 and the arc-shaped beams 31, which leads to the instability of the support on the slope and the side overturning of the support, and causes installation hidden dangers.

[0045] Additional technical effects of the present application are as follows:

[0046] As shown in Figure 1 and Figure 6 After the bracket is installed in place, a square clamp 101 can be installed at the connection between the cross beam 3 and the arc-shaped beam 31 to reinforce the connection between the cross beam 3 and the arc-shaped beam 31 and improve stability. Example 2

[0047] Based on example 1, as shown in Figures 8-10 It also includes a pad 5 and a connecting pin 6; two pads 5 are connected to each circular clamp 4, and the pad 5 is a semicircular arc plate with an arc of 180°; one connecting pin 6 is connected to each arc-shaped beam 31; the connecting pin 6 is composed of a connecting column 61, a ball pin 62, and a limiting pin 63; the ball pin 62 and the limiting pin 63 are screwed through a screw rod and the connecting column 61; the ball pin 62 is connected to the arc-shaped beam 31, and the screw rod of the limiting pin 63 is screwed to the transverse edge 51 of the pad 5, and the transverse edge 51 is provided with a threaded hole.

[0048] It also includes a limiting assembly, which includes a threaded rod 7, a screw ring 8, and a connecting cylinder 9; the lower side of all the mounting beams 1 is commonly connected to a threaded rod 7; one screw ring 8 is connected to each end of the threaded rod 7; one connecting cylinder 9 is rotatably connected to each screw ring 8; an extrusion block 91 is fixedly connected to the end of the connecting cylinder 9 away from the screw ring 8.

[0049] The inner arc surface of the pad 5 is provided with a rubber pad to increase the friction between the pad and the pole and improve stability.

[0050] The extrusion block 91 is arc-shaped and made of hard rubber, which can adapt to the outer surface of the pole, improve the stability of the limiting, and has a good service life.

[0051] The side of the extrusion block 91 facing the pole is provided with rough texture to increase the friction between the extrusion block and the pole and improve stability.

[0052] The operation steps of the present embodiment are as follows:

[0053] During the installation of the transformer, the bracket and the transformer are lifted off the ground, and the Figure 2As shown, after the arc-shaped beams 31 are in contact with each other, a worker installs the circular clamps 4 on the power poles on the ground, and the circular clamps 4 are located above the arc-shaped beams 31, at this time, the circular clamps 4 are not tightened, and a gap is left between the circular clamps 4 and the power poles, then two pads 5 are inserted into the gap, the transverse edges 51 of the pads 5 are in contact with the upper surfaces of the circular clamps 4, then a connecting column 61 is screwed on the ball head pin 62 on each arc-shaped beam 31, and then the limiting pin 63 on the transverse edge 51 is screwed, so that the limiting pin 63 is screwed with the other end of the connecting column 61, and a complete connecting pin 6 is formed, thereby the connecting pin 6 connects the pad 5 and the arc-shaped beam 31, and the pad 5 is connected with the connecting pin 6 through the ball head pin 62, so that the pad 5 and the connecting pin 6 can move relatively, then the worker lifts the support and the transformer to the installation height through the manual hoist, the circular clamps 4 are pushed upward by the arc-shaped beams 31, and the pads 5 are driven to move upward along the power poles (it should be noted that at this time, the circular clamps 4 are not tightened, and then the circular clamps 4 and the pads 5 can be smoothly moved upward along the power poles), after the support is moved to the installation position, the worker tightens the circular clamps 4, the circular clamps 4 extrude the pads 5 to be attached to the power poles, and a fixed state is formed, at this time, the support is hoisted on the circular clamps 4 and the pads 5 through the connecting pin 6, then the worker detects the inclination degree of the support and the ground through the level, if the support and the ground are inclined, the worker rotates the limiting pin 63, so that the length of the connecting pin 6 on the downward side is shortened, and the length of the connecting pin 6 on the other side is correspondingly lengthened, so that the lengths of the connecting pins 6 on both sides are changed, so as to adjust the support to be horizontal, then the worker rotates the screw ring 8, the connecting barrel 9 is pushed to move toward the power pole along the threaded rod 7, the extrusion block 91 is extruded on the surface of the power pole, the position of the support and the two power poles is limited, the support is fixed, and the installation of the support and the transformer is completed.

[0054] In addition, after the above step operation is completed, a circular clamp 4 can be additionally arranged below the arc-shaped beam 31 of the support, so as to support the support and ensure stability.

[0055] According to the above steps, it can be known that the support has the following effects:

[0056] When the electric pole is slightly inclined due to the influence of the slope terrain, if the support and the transformer are installed on the inclined electric pole, the weight will be concentrated on one side of the cross beam 3, which will cause the uneven force of the support, affect the stability between structures, and easily cause the problem of increasing the inclination angle of the electric pole. Therefore, during installation, the support is first lifted off the ground by the manual hoist, the workers install the circular hoop 4 and the cushion block 5 on the part of the electric pole above the arc-shaped beam 31 on the ground, connect the circular hoop 4 and the cushion block 5 with the support through the connecting pin 6, then lift the support together with the circular hoop 4 and the cushion block 5 to the installation height, tighten the circular hoop 4 to fix it on the electric pole, and then adjust the support to the horizontal position by changing the length of each connecting pin 6 and the relative movement between the cushion block 5 and the connecting pin 6 connected by the ball head pin 62, so as to avoid the problem that the support is installed on the inclined electric pole and the whole is inclined, the weight of the transformer is concentrated on one side of the cross beam 3, the force of the support is uneven, the stability between structures is affected, and the problem of increasing the inclination angle of the electric pole is easily caused. Finally, the position of the support between the two electric poles is limited by the limiting assembly to prevent the support from moving after installation due to the relative movement between the cushion block 5 and the connecting pin 6 connected by the ball head pin 62.

[0057] Although the present disclosure has been described only with respect to a limited number of embodiments, those skilled in the art who benefit from the present disclosure will understand that various other embodiments can be designed without departing from the scope of the present application. Therefore, the scope of the present application should be limited only by the appended claims.
