Description

Technical Field

[0001] This utility model relates to the field of bolt tightening force testing technology, and in particular to an auxiliary tool for testing the bolt tightening force of wind power generation equipment. Background Technology

[0002] Wind power generation equipment is usually located at high altitudes and in harsh natural environments. As a key component connecting various parts, bolts may gradually loosen or even fall off if the tightening force is insufficient, under the action of external forces such as strong winds and vibrations. This could lead to the loss of connection of important components such as blades and cause serious safety accidents. Therefore, it is necessary for staff to test the tightening force of bolts. A common tool for testing tightening force is a torque wrench, which can determine whether the bolt has become loose by measuring the torque again, and thus infer whether the bolt tightening force has changed.

[0003] Currently, existing torque wrenches mainly consist of a handle and a wrench head. When not in use, the wrench head is always exposed. Therefore, when workers move the torque wrench in narrow passages or in poor lighting conditions, the wrench head is prone to accidentally hitting hard objects, causing it to chip, deform, or crack. This affects the accuracy of its fit with bolts and nuts, thus affecting the accuracy of the test data. To address this issue, we propose an auxiliary tool for testing the bolt tightening force of wind power generation equipment. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary tool for detecting the bolt tightening force of wind power generation equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary tool for testing the bolt tightening force of wind power generation equipment includes a handle, a wrench head connected to the end of the handle, and a protective cover covering the outside of the wrench head. Limiting rods are symmetrically inserted inside the protective cover, and the longitudinal section of the limiting rods is set as a T-shaped structure. A display screen is provided on the side of the handle.

[0007] Preferably, a set of limiting rods is symmetrically inserted with limiting posts inside, and the ends of the limiting posts are connected by a pull plate. The protective cover has evenly spaced positioning grooves that are adapted to the limiting posts on its side, and a protective ring is sleeved on the outside of the limiting rod.

[0008] Preferably, a slot is provided at the center of one set of limiting rods, and a connecting spring is vertically connected to the inner wall of the slot, the other end of the connecting spring being connected to the pull plate.

[0009] Preferably, the protective cover has a rubber sleeve bonded to its side, and the rubber sleeve has a U-shaped structure.

[0010] Preferably, the rubber sleeve has uniformly spaced receiving grooves inside, and the inner walls of the receiving grooves are all connected to rotating rollers via bearings.

[0011] Preferably, threaded rods are connected to the sides of the limiting rods that are close to each other, and the handle has a threaded groove inside that is adapted to the threaded rod.

[0012] Preferably, the outer side of the handle is covered with an anti-slip sleeve, and the outer wall of the anti-slip sleeve is evenly distributed with anti-slip particles.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device is equipped with a protective cover and a limiting rod. During use, the protective cover and the limiting rod work together to meet the rotation requirements of the protective cover. While not affecting the normal use of the wrench head, it can also surround and protect the outside of the wrench head when it is not in use, so as to prevent the wrench head from colliding with hard objects and being damaged, thereby effectively ensuring the service life of the wrench head.

[0015] 2. This device is equipped with a rubber sleeve and a rotating roller. During use, the rubber sleeve and the rotating roller work together to reduce the external force on the end of the protective cover, thereby protecting the protective cover and ensuring its protective effect on the wrench head.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 An auxiliary tool for testing the bolt tightening force of wind power generation equipment includes a handle 1, a wrench head 2 connected to the end of the handle 1, and a protective cover 3 covering the outside of the wrench head 2. Limiting rods 4 are symmetrically inserted inside the protective cover 3, and the longitudinal section of the limiting rods 4 is set as a T-shaped structure. A display screen 12 is provided on the side of the handle 1. The display screen 12 can display the tested bolt tightening force data. It is used in conjunction with the wrench head 2 and the handle 1. The testing principle is not described in detail here.

[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a set of limiting rods 4 has symmetrically inserted limiting posts 6 inside, and the ends of the limiting posts 6 are connected by the pull plate 5. The protective cover 3 has evenly opened positioning grooves 13 that are adapted to the limiting posts 6 on its side. The limiting rods 4 are fitted with protective rings 8 on their outer sides. During use, the protective rings 8 can maintain the height of the box when the pull plate 5 is not under tension, thereby protecting the pull plate 5. Through the cooperation of the limiting posts 6 and the pull plate 5, the protective cover 3 can be easily fixed when rotated to a suitable angle, so as to effectively prevent the protective cover 3 from easily shifting during the protection process, thus effectively improving the protection effect of this device on the wrench head 2.

[0024] Furthermore, refer to Figure 4 It can be seen that a slot is provided at the center of one of the limiting rods 4, and a connecting spring 7 is vertically connected to the inner wall of the slot. The other end of the connecting spring 7 is connected to the pull plate 5. During use, the elasticity of the connecting spring 7 itself can effectively ensure the tightness of the limiting post 6 when it is inserted into the positioning slot 13 inside the protective cover 3.

[0025] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the protective cover 3 has a rubber sleeve 10 glued to its side, and the rubber sleeve 10 is designed with a U-shaped structure. During use, the rubber sleeve 10 with the U-shaped structure can cover and protect the end of the protective cover 3. The rubber sleeve 10 is made of rubber, which can absorb the external force on the protective cover 3 to ensure the service life of the protective cover 3.

[0026] Furthermore, refer to Figure 1 and Figure 3It can be seen that the rubber sleeve 10 has uniformly opened receiving grooves inside, and the inner wall of the receiving grooves is connected to the rotating rollers 11 through bearings. When the end of the protective cover 3 is subjected to external force, the external force can first come into contact with each group of rotating rollers 11 to drive the rotation of each group of rotating rollers 11, thereby converting sliding friction into rolling friction to achieve further protection of the end of the protective cover 3.

[0027] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the limiting rods 4 are connected to threaded rods 9 on their respective sides. The handle 1 has a threaded groove that matches the threaded rod 9. During use, by cooperating with the threaded rod 9 and the threaded groove, the operator can rotate the limiting rod 4 to drive the threaded rod 9 to rotate at the same time, thereby removing the two sets of limiting rods 4 from the side of the handle 1 and the inside of the protective cover 3, which makes it easier for the operator to replace the damaged protective cover 3.

[0028] Furthermore, refer to Figure 1 It can be seen that the outer side of the handle 1 is covered with an anti-slip sleeve 14, and the outer wall of the anti-slip sleeve 14 is evenly distributed with anti-slip particles. The anti-slip sleeve 14 is made of rubber. During use, the reliability of the device when holding the handle 1 can be guaranteed by the cooperation between the anti-slip sleeve 14 and the anti-slip particles.

[0029] Working Principle: In use, the operator can lift the pull plate 5, which will cause the limiting post 6 to be pulled out from the positioning groove 13 inside the protective cover 3. Then, the operator can rotate the protective cover 3 so that it no longer covers the outside of the wrench head 2. When the protective cover 3 is rotated to a suitable angle, the operator can stop pulling the pull plate 5, so that the limiting post 6 can be re-embedded into the other two sets of positioning grooves 13 inside the protective cover 3 to achieve the same limiting effect. Then, the operator can insert the wrench head 2 into the bolt that needs to be tested on the wind power generation equipment. By rotating the bolt, the test data can be displayed on the display screen 12. After use, the operator can pull the pull plate 5 again to rotate the protective cover 3 again, so that it covers and protects the end of the wrench head 2 again, ensuring the safety of the wrench head 2 when it is not in use. The above is the complete working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
