Description
Technical Field
[0001] The invention relates to the technical field of transformer installation, and in particular to a counterweight body of a transformer installation vehicle. Background Art
[0002] Existing current transformers require regular maintenance such as inspection and replacement, with inspections being performed at least once a year, during which they often need to be replaced.
[0003] The current transformer of the high-voltage cabinet is heavy, and the space inside the high-voltage cabinet is small. It is time-consuming and laborious to manually lift the current transformer in the cabinet for installation. Therefore, in reality, maintenance personnel generally use an installation vehicle to assist in the installation of the current transformer. The existing installation vehicle includes a vehicle body and a cantilever installed on the front side of the vehicle body; the front end of the cantilever is used to lift the current transformer to be installed. Due to the heavy weight of the current transformer, in order to prevent the installation vehicle from tipping forward under the gravity of the current transformer, there are two existing installation vehicles. The first solution is as shown in the application number C Patent N2013101564276 installs a heavy counterweight at the bottom of the vehicle body. Although this solution is simple, the counterweight is heavy, which increases the cost on the one hand and is inconvenient to carry up and down on the other hand; the second solution, such as patent application number CN2022101182181, extends the front end of the trolley to below the front end of the cantilever. Although this approach can prevent the installation vehicle from tipping forward, the front end of the trolley is too forward and the front end of the trolley is easy to hit the high-voltage cabinet, that is, the front end of the cantilever cannot extend into the high-voltage cabinet. Summary of the invention
[0004] In order to solve the above-mentioned shortcomings of the existing transformer installation vehicle, the present invention provides a transformer installation vehicle counterweight body, which reduces the weight of the counterweight block and prevents the installation vehicle from tipping forward.
[0005] To achieve the above object, the present invention adopts the following technical solution: A counterweight body for a transformer installation vehicle comprises a vehicle frame, rollers and support columns, wherein the rollers are mounted at the front and rear ends of the vehicle frame, the support columns are vertically mounted on the upper side of the vehicle frame, a mounting position for mounting a cantilever is arranged on the front side of the support column, the distance that the front end of the vehicle frame protrudes forward from the support column is smaller than the distance that the cantilever protrudes forward from the support column, the vehicle body further comprises a lever and a counterweight body, the end of the lever is mounted on the support column and extends back to the cantilever, the distance that the lever protrudes backward from the support column is larger than the distance that the cantilever protrudes forward from the support column, and the counterweight body is arranged at one end of the lever away from the support column and can slide along the lever.

[0011] Furthermore, the counterweight body also includes a rubber pad installed at the lower end of the telescopic body.
[0012] Through the above arrangement, the rubber pad plays a buffering role, reduces the impact force when the lower end of the telescopic body contacts the ground, and prevents the vehicle body from tipping over due to large vibration.

[0028] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.
[0029] like Figures 1 to 4 As shown, a counterweight body of a transformer installation vehicle includes a frame 3, rollers 4 and support columns 5, the rollers 4 are installed at the front and rear ends of the frame 3, the support columns 5 are vertically installed on the upper side of the frame 3, and a mounting position for installing a cantilever 6 is arranged on the front side of the support column 5. The distance that the front end of the frame 3 protrudes forward from the support column 5 is less than the distance that the cantilever 6 protrudes forward from the support column. The body also includes a lever 7 and a counterweight body 8. The end of the lever 7 is installed on the support column 5 and extends back to the cantilever 6. The distance that the lever 7 protrudes backward from the support column is greater than the distance that the cantilever protrudes forward from the support column. The counterweight body 8 is arranged at one end of the lever 7 away from the support column 5 and can slide along the lever.
[0030] Through the above arrangement, firstly, the length of the protruding support column 5 at the front end of the frame 3 is small, so as to prevent the front end of the frame 3 from hitting the high-voltage cabinet when being pushed forward, so that the front end of the cantilever 6 can be extended into the high-voltage cabinet, so as to facilitate the installation of the transformer 200; secondly, by utilizing the principle of the lever 7, the counterweight 8 can prevent the vehicle body from tipping forward with a lighter weight; thirdly, it can adapt to transformers 200 of different weights.
[0031] The cantilever 6 can be horizontally mounted on the mounting position on the front side of the support column 5, and the cantilever 6 extends in the front-rear direction. Figure 1 The front and rear directions of the vehicle body are indicated in the figure. The front end of the frame 3 and the counterweight 8 can prevent the vehicle body from tipping forward. The counterweight 8 and the lever 7 mainly offset the forward moment of the mutual inductor 200 backward to prevent the vehicle body from tipping forward. In the present application, the distance L1 of the front end of the frame 3 protruding forward from the support column 5 is less than or equal to the distance L2 of the cantilever 6 protruding forward from the support column 5. Specifically, the ratio of the distance L1 of the front end of the frame 3 protruding forward from the support column 5 to the distance L2 of the cantilever 6 protruding forward from the support column 5 is less than or equal to 1 / 2, so as to prevent the vehicle body from tipping forward when moving forward. The lever 7 is mounted horizontally on the upper end of the support column 5, and the lever 7 extends backward. Specifically, the ratio of the distance L2 of the cantilever 6 protruding forward from the support column 5 to the distance L3 of the lever 7 protruding backward from the support column 5 is less than or equal to 1 / 2. In reality, the mass of a transformer 200 is about 17 kg. When the counterweight 8 is set at the rear end of the lever 7, the weight of the counterweight 8 is less than half of the weight of the transformer 200, which reduces the weight of the counterweight 8 and facilitates the up and down transportation of the vehicle body. As an implementation method, a handrail can be installed at the rear end of the lever 7 to facilitate maintenance personnel to push and pull the vehicle body at the rear side of the vehicle body. The counterweight body 8 of the present application exerts a backward torque on the support column 5 and balances the forward torque of the mutual inductor 200 on the support column 5; when the counterweight body 8 slides backward along the lever 7, a mutual inductor 200 with a heavier weight can be placed at the front end of the cantilever 6, and when the counterweight body 8 slides forward along the lever 7, a mutual inductor 200 with a lighter weight can be placed at the front end of the cantilever 6.
[0032] As an implementation method, the distance L4 that the frame 3 protrudes backward from the support column 5 is smaller than the distance L3 that the lever 7 protrudes backward from the support column. The counterweight body 8 includes a sliding sleeve 81 and a telescopic body 82. The sliding sleeve 81 is slidably connected to the lever 7. The upper end of the telescopic body 82 is connected to the sliding sleeve 81, and the lower end of the telescopic body 82 can be raised and lowered.
[0033] Through the above arrangement, first, the weight of the vehicle body is further reduced; second, the rear end of the vehicle body is prevented from colliding with the feet of the maintenance personnel; third, the lower end of the telescopic body 82 is prevented from colliding with the feet of the maintenance personnel; and fourth, after the mutual inductor 200 is separated from the cantilever 6, the vehicle body can be prevented from tipping backwards.
[0034] Specifically, when the maintenance personnel push the vehicle body toward the high-voltage cabinet, the telescopic body 82 contracts and the height of the lower end of the telescopic body 82 is raised to prevent the maintenance personnel's feet from touching the telescopic body 82. After the front end of the cantilever 6 is extended into the high-voltage cabinet, the telescopic body 82 is extended and the lower end of the telescopic body 82 is close to the ground. In the present application, the distance between the lower end of the telescopic body 82 and the ground is less than or equal to 3 cm. After the maintenance personnel enter the high-voltage cabinet and install the transformer 200 in the high-voltage cabinet, the transformer 200 is separated from the cantilever 6. At this time, without the gravity of the transformer 200, the vehicle body tilts backward under the gravity of the counterweight 8, and the lower end of the telescopic body 82 immediately touches the ground to prevent the vehicle body from tipping backward.
[0035] As an implementation method, the telescopic body 82 includes a sleeve 821, a sliding rod 822 and a locking mechanism 823. The upper end of the sleeve 821 is fixedly connected to the sliding sleeve 81, the upper end of the sliding rod 822 is slidably connected in the sleeve 821, the lower end of the sliding rod 822 protrudes from the lower end of the sleeve 821, and the locking mechanism 823 locks the sliding rod 822 in the sleeve 821.
[0036] As an implementation method, when the telescopic body 82 is contracted to its shortest length, the distance from the lower end of the telescopic body 82 to the ground is greater than or equal to 50 centimeters, and when the telescopic body 82 is extended to its longest length, the distance from the lower end of the telescopic body 82 to the ground is less than or equal to 5 centimeters.
[0037] Through the above arrangement, after the telescopic body 82 is retracted, when the maintenance personnel push the vehicle body to walk, their feet are not likely to collide with the telescopic body 82; after the telescopic body 82 is extended, the distance between the telescopic body 82 and the ground is short, which can prevent the vehicle body from tipping backwards.
[0038] As an implementation method, a long hole 824 extending vertically is provided on the sleeve 821, and the locking mechanism 823 includes a stud 8231, a pressure plate 8232 and a handwheel 8233. The stud 8231 passes through the long hole 824 and is threadedly connected to the sliding rod 822. The pressure plate 8232 is threadedly connected to the stud 8231 and is pressed against the outside of the sleeve 821. The handwheel 8233 is fixedly connected to the outer end of the stud 8231.
[0039] Through the above arrangement, the tightness of the locking mechanism can be adjusted by turning the hand wheel.
[0040] The handwheel 8233 of the present application facilitates the rotation of the stud 8231. After the handwheel 8233 is tightened, the pressure plate 8232 is pressed against the outer wall of the sleeve 821, and the sliding rod 822 is locked in the sleeve 821 under the action of friction; after the handwheel 8233 is loosened, the stud 8231 rotates outward, driving the pressure plate 8232 to loosen the outer wall of the sleeve 821. At this time, the sliding rod 822 can slide up and down to adjust the length of the telescopic body 82.
[0041] As an implementation method, the counterweight body 8 further includes a rubber pad 83 installed at the lower end of the telescopic body 82 .
[0042] Through the above arrangement, the rubber pad 83 plays a buffering role, reducing the impact force when the lower end of the telescopic body 82 contacts the ground, and preventing the vehicle body from tipping over due to large vibration.
[0043] As an implementation method, the vehicle body further includes an inclined support rod 10 , the lower end of the support rod 10 is mounted on the support column 5 , and the upper end of the support rod 10 is mounted on an end of the lever 7 close to the support column 5 .
[0044] Through the above arrangement, the support rod 10 supports the lever 7 and improves the strength of the lever 7.
[0045] As an implementation method, the roller 4 is configured as a universal wheel, and the universal wheel disposed at the rear end of the frame 3 has a braking function.
[0046] Through the above arrangement, the frame 3 can be prevented from sliding on the ground when the maintenance personnel install the mutual inductor 200, thereby improving the safety of the operation.
[0047] As an implementation method, the frame 3 includes a front leg 31 and two rear legs 32. The front leg 31 extends in the front-to-back direction, and the two rear legs 32 are forked and arranged at the rear end of the front leg 31. A roller 4 is arranged at the front end of the front leg 31 and the rear end of the rear leg 32.
[0048] Through the above arrangement, the structure of the frame 3 is simplified, and while the weight of the frame 3 is reduced, the three rollers 4 are arranged in a triangle to ensure the stability of the frame 3.
[0049] As an implementation method, both the front legs and the rear legs are square tube structures.
[0050] Through the above arrangement, the frame weight is made lighter.
[0051] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
