Description

An easy-to-fix workbench

Technical field

The utility model relates to the technical field of workbench, specifically a workbench that is easy to fix.

Background technique

Due to the complex terrain during power maintenance, the commonly used maintenance method is to erect steel pipe scaffolding for maintenance work. However, this method is not only time-consuming and labor-intensive, but also involves great safety risks. At power construction sites, especially during power emergency repairs, It is often necessary to perform bench work, drilling, grinding and other processes on power equipment parts, which are inseparable from traditional tools such as bench drills and bench drills.

Currently constructed substations basically have no maintenance rooms and are not equipped with maintenance platforms. Therefore, processes such as benchwork, drilling, and grinding cannot be carried out. Large-scale lift forklifts or cranes must be used to transport from the operation room to the substation, which is extremely inconvenient. The above situation seriously affects Efficiency of electrical emergency repairs.

In the prior art, patent number CN211664685U discloses an electric power maintenance workbench, which includes a base. A scissor lift is symmetrically fixed on the top of the base, and a support platform is fixed on the top of the scissor lift. The support There are support frames fixed at equal distances on the top of the platform. The height of the inspection platform can be adjusted conveniently by setting up a scissor lift to facilitate maintenance. By setting the support frames, the support frames are fixedly connected with screws. Multiple sets of support frames can be used in pairs. The fixed connection between them realizes the adjustment of the height of the electrical maintenance workbench, which facilitates the adjustment of the height of the maintenance workbench and can meet different use needs. The electric hoist can lift the hanging basket through the wire rope, and the hanging basket can lift some Maintenance tools and electrical parts are lifted and transported to facilitate maintenance operations. The personal safety of maintenance personnel can be ensured by setting up protective fences.

Although this technical solution can adjust the height of the inspection platform and meet different usage needs, the above technical solution only fixes the moving wheel through the foot brake on the moving wheel when in use. During the maintenance process, when the workbench When the overall vibration occurs, it is easy to cause the foot brake to become loose, causing the workbench to shift, which will affect the electrical maintenance work of the staff.

Please refer to Figure 1-5. A workbench that is easy to fix includes an inspection platform 1. The bottom of the inspection platform 1 is fixed with symmetrically arranged moving wheels. The bottom of the inspection platform 1 is provided with an installation cavity 2. The inspection platform 1 The bottom of the mounting base 3 is located on both sides of the mounting cavity 2, and two sets of symmetrically arranged mounting bases 3 are fixedly installed. An extrusion cam 4 is rotated inside the mounting base 3, and a motor is fixedly installed at the corresponding position between the outer wall of the mounting base 3 and the end of the extrusion cam 4. 5.

The utility model proposes an easy-to-fix workbench. When in use, workers can conduct electrical maintenance or emergency repairs through the maintenance bench 1. The main structure in this technical solution is consistent with an electric power maintenance workbench disclosed in the patent number CN211664685U. The main structure of the frame is similar. In this technical solution, when the user needs to board the inspection platform 1 to perform electrical work, the user can move the inspection platform 1 to the designated working position through the moving wheels, and then the user can drive There are two motors 5 located at the bottom of the inspection platform 1. The two motors 5 can be adjusted to a synchronous forward or reverse rotation frequency during the pre-debugging process. When the motors 5 are started, they can drive the two mounting bases 3. The extrusion cam 4 rotates. When the extrusion cam 4 is in a horizontal state, it can be stored in the installation cavity 2 at the bottom of the maintenance platform 1. When the extrusion cam 4 rotates under the drive of the motor 5, it can simultaneously rotate to the vertical position. state to support the inspection platform 1, or it can be rotated to the oppositely arranged "eight" shape to support the inspection platform 1. When the two extrusion cams 4 maintain the support state of the inspection platform 1, the bottom of the inspection platform 1 can be moved The separation of the wheels from the ground can avoid the impact of the loosening of the movable wheels caused by vibrations during operation of the inspection platform 1 on the maintenance walking, making the entire inspection platform 1 stay more stable in the working position.

Further, as shown in Figure 2, the bottom of the maintenance platform 1 is provided with a pad 6 below the two extrusion cams 4. The upper end surface of the pad 6 is movably connected to the outer wall of the extrusion cam 4. The arrangement of the pad 6 Further enhancing the friction between the extrusion cam 4 and the ground when maintaining the support state of the inspection platform 1 can further prevent the inspection platform 1 from being displaced during use.

Further, as shown in Figures 3 and 4, a plurality of chute 7 is provided on the outer wall of the extrusion cam 4. A sliding rod 9 is slidably installed inside the chute 7, and a connecting block 10 is fixedly installed on the outer wall of the sliding rod 9. The lower end of the connecting block 10 is hingedly arranged at a position corresponding to the upper end surface of the backing plate 6. When in use, the sliding rod 9 and the connecting block 10 serve as a connection between the extrusion cam 4 and the backing plate 6, so that the upper surface of the backing plate 6 It is always in contact with the outer wall of the extrusion cam 4, so that when the extrusion cam 4 rotates, its outer wall can always remain in contact with the upper surface of the pad 6, so that the extrusion cam 4 can be in contact with the upper surface of the pad 6. produce relative sliding.

Further, as shown in Figure 5, rolling rings 11 are installed at both ends of the sliding rod 9. The arrangement of the rolling rings 11 can convert the sliding friction between the outer wall of the end of the sliding rod 9 and the inner wall of the chute 7 into rolling friction. , thereby making the slide rod 9 slide more flexibly inside the chute 7 .

Further, as shown in Figure 2, a plurality of anti-slip strips 8 are fixedly connected to the bottom surface of the pad 6. The anti-slip strips 8 are elastically arranged. The arrangement of the anti-slip strips 8 can increase the friction between the bottom of the pad 6 and the ground. In turn, the backing plate 6 supports the inspection platform 1 more stably when in contact with the ground.

Further, as shown in Figure 3, a plurality of the chute 7 is evenly distributed on the outer wall of the extrusion cam 4. The chute 7 and the sliding rod 9 and connecting block 10 slidably installed inside the chute 7 are located between the chute 7 and the pad. The plates 6 are evenly distributed so that the upper surface of the backing plate 6 receives uniform force everywhere when the extrusion cam 4 rotates.

Further, as shown in Figure 2, two sets of mounting seats 3 are located at both ends of the bottom surface of the maintenance platform 1, and the extrusion cams 4 in the mounting seats 3 are respectively located at both ends of the maintenance platform 1, so that they can be in a supporting state. At this time, the maintenance platform 1 is supported more stably.

Obviously, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. An exhaustive list of all implementations is neither necessary nor possible. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall be included in the protection scope of the claims of the present utility model.
