Description

Technical Field

[0001] This utility model relates to the field of power load technology, specifically to power-specific loads. Background Technology

[0002] With the continuous expansion of various power engineering and other basic construction projects, the quality of civil engineering works needs to be inspected by professionals. This requires the use of corresponding mobile loads for power engineering testing. However, existing mobile loads for power engineering have certain drawbacks, such as poor mobility, inability to move in all directions, and poor stability after movement. As a result, the mobile load may move during operation, increasing the difficulty of the operator's work and reducing the usability of the mobile load. Patent documents have now been issued to improve this.

[0003] Chinese patent CN210222150U discloses a mobile load for power engineering. The mobile load includes: a housing and a movable slot, the top of which is fixed to the bottom of the housing; a walking structure disposed on the top of the inner wall of the movable slot, the walking structure including a rotating plate, the top of which is rotatably connected to the top of the inner wall of the movable slot; and a buffer slot, the top of which is fixed to the bottom of the rotating plate, with a buffer plate slidably connected between the two sides of the inner wall of the buffer slot. The mobile load for power engineering provided by this invention is simple to operate and convenient to use. Four support legs and four stable anti-slip pads provide stable support for the equipment, preventing movement during operation due to the presence of wheels. The retraction and extension of the support legs effectively solves the problem of stable support, further facilitating operation by staff.

[0004] Although the aforementioned patent uses multiple support legs to support the shell and prevent it from moving arbitrarily, it requires manual operation of multiple support legs to move them downwards to support the ground. The overall weight of the shell is relatively heavy, and manual operation is time-consuming and laborious. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dedicated power load, which solves the problems of needing to manually drive multiple support legs to move them downwards to support the ground, resulting in a heavy overall weight of the casing and time-consuming and laborious manual operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dedicated power load, comprising a load housing, a control panel mounted on the top of the load housing, several power input interfaces on one side of the load housing, pulleys fixedly connected to all four sides of the bottom of the load housing, a fixed frame fixedly connected to the rear of the load housing, a motor fixedly connected to the top of the inner cavity of the fixed frame, a threaded rod fixedly connected to the output shaft of the motor via a coupling, one end of the threaded rod being fixedly connected to the bottom of the inner cavity of the fixed frame via a bearing, a threaded sleeve being threadedly connected to the surface of the threaded rod, a sliding groove being provided at the front of the inner cavity of the fixed frame, a slider being slidably connected to the threaded sleeve inside the sliding groove, connecting frames fixedly connected to both sides of the threaded sleeve, strip grooves being provided on both sides of the front and rear of the load housing, sliding plates being slidably connected to the inside of the strip grooves via sliders, one side of the connecting frame being fixedly connected to the rear sliding plate, and a support plate being fixedly connected between the opposite sides of the front and rear sliding plates.

[0007] Preferably, a rectangular groove is provided at the bottom of the support plate, and a movable plate is slidably connected inside the rectangular groove.

[0008] Preferably, the front and rear parts of the rectangular groove cavity are provided with limiting grooves, and the interior of the limiting grooves is slidably connected to the moving plate by a slider.

[0009] Preferably, a spring is fixedly connected between one side of the inner cavity of the rectangular groove and one side of the movable plate.

[0010] Preferably, a trapezoidal plate is fixedly connected to the top of the movable plate, and a movable groove adapted to the trapezoidal plate is provided on the top of the support plate.

[0011] Preferably, inclined blocks adapted to the trapezoidal plate are fixedly connected to both sides of the bottom of the load housing.

[0012] Beneficial effects

[0013] This utility model provides a dedicated power load. Compared with existing technologies, it has the following advantages:

[0014] (1) This utility model controls the motor to drive the threaded rod to rotate, the threaded rod will drive the threaded sleeve to move downward, the threaded sleeve will drive the two connecting frames to move downward, and the connecting frames will drive the support plate to move downward through the sliding plate, so that the support plate contacts the ground and supports the load shell. It can automatically support the load shell without manual operation, which is more time-saving and labor-saving.

[0015] (2) The utility model makes contact with the downward movement of the support plate, and the trapezoidal plate on the support plate no longer contacts the inclined block. Through the action of the spring, the spring pushes the moving plate to move outward, so that the moving plate extends out of the rectangular groove, increasing the support area of ​​the support plate and improving the stability of the load shell support.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-5This utility model provides a technical solution: a dedicated power load, including a load housing 1, a control panel 2 mounted on the top of the load housing 1, several power input interfaces 3 on one side of the load housing 1, pulleys 4 fixedly connected to all four sides of the bottom of the load housing 1, a fixing frame 5 fixedly connected to the rear of the load housing 1, a motor 6 fixedly connected to the top of the inner cavity of the fixing frame 5, the motor 6 being a servo motor electrically connected to a battery inside the load housing 1 and controlled by a control switch, and a threaded rod 7 fixedly connected to the output shaft of the motor 6 via a coupling. One end is fixedly connected to the bottom of the inner cavity of the fixed frame 5 via a bearing. A threaded sleeve 8 is threadedly connected to the surface of the threaded rod 7. A sliding groove 9 is provided at the front of the inner cavity of the fixed frame 5. The inside of the sliding groove 9 is slidably connected to the threaded sleeve 8 via a slider. A connecting frame 10 is fixedly connected to both sides of the threaded sleeve 8. A strip groove 11 is provided on both sides of the front and rear of the load housing 1. A sliding plate 12 is slidably connected to the inside of the strip groove 11 via a slider. One side of the connecting frame 10 is fixedly connected to the rear sliding plate 12. A support plate 13 is fixedly connected between the opposite sides of the two sliding plates 12.

[0024] Furthermore, in order to facilitate increasing the support area of ​​the support plate 13, a rectangular groove 14 is provided at the bottom of the support plate 13. A movable plate 15 is slidably connected inside the rectangular groove 14. Limiting grooves 16 are provided at the front and rear of the inner cavity of the rectangular groove 14. The inside of the limiting groove 16 is slidably connected to the movable plate 15 through a slider.

[0025] Furthermore, in order to facilitate the resetting of the movable plate 15, a spring 17 is fixedly connected between one side of the inner cavity of the rectangular groove 14 and one side of the movable plate 15. A trapezoidal plate 19 is fixedly connected to the top of the movable plate 15. A movable groove 18 adapted to the trapezoidal plate 19 is opened on the top of the support plate 13. Inclined blocks 20 adapted to the trapezoidal plate 19 are fixedly connected to both sides of the bottom of the load housing 1.

[0026] In use, the load is pushed to the designated position by multiple pulleys 4, and then the motor 6 is controlled to drive the threaded rod 7 to rotate. The threaded rod 7 will drive the threaded sleeve 8 to move downward. The threaded sleeve 8 will drive the sliding plate 12 to move downward through the two connecting brackets 10, so that the sliding plates 12 on both sides drive the support plate 13 to move downward. The support plate 13 contacts the ground downward, and the two support plates 13 will support the load housing 1, so that the multiple pulleys 4 are away from the ground, and support and stabilize the load housing 1.

[0027] As the two support plates 13 move downward, the trapezoidal plate 19 on the support plate 13 moves downward synchronously. After the trapezoidal plate 19 moves away from the inclined block 20, it is pushed by the force of the spring 17 to extend the moving plate 15 out of the rectangular groove 14, so that the two moving plates 15 extend to both sides and increase the support area of ​​the support plate 13.

[0028] When it is necessary to move the load housing 1, the motor 6 drives the threaded rod 7 to rotate in the opposite direction. The threaded rod 7 will drive the two support plates 13 to move upward through the threaded sleeve 8 and the connecting frame 10, so that the two support plates 13 return to their original position and the multiple pulleys 4 contact the ground. The upward movement of the support plates 13 will drive the trapezoidal plate 19 to move upward. The inclined surface of the inclined block 20 will push the inclined surface of the trapezoidal plate 19, pushing the trapezoidal plate 19 to move towards the middle and return to its original position. The trapezoidal plate 19 will drive the moving plate 15 to move into the rectangular groove 14 and return to its original position, thereby driving the load housing 1 to move through the multiple pulleys 4.
