Abstract
Description
Technical Field
[0001] This disclosure relates to the field of torque wrench application technology, and more specifically, to a safety fixture for a hydraulic torque wrench. Background Technology
[0002] During regular maintenance of wind turbine units, a hydraulic torque wrench is required to check the torque of the bolts on the entire unit. If the bolts do not rotate under the specified torque value, the torque is considered to be qualified.
[0003] Currently, during operation, it is necessary to hold the torque wrench by hand, but this is very dangerous and can easily trap and injure the hand. In addition, a fulcrum needs to be selected during the operation, and if the fulcrum is faulty, there is also a risk of trapping the hand. Utility Model Content
[0004] The purpose of this disclosure is to provide a safety fixture for a hydraulic torque wrench that can solve the above-mentioned technical problems.
[0005] To achieve the above objectives, this disclosure provides a safety fixture for a hydraulic torque wrench, comprising: a mounting component; a hand-held component disposed on the mounting component; and a connecting component disposed on the mounting component for detachable connection with the hydraulic torque wrench.
[0006] Optionally, the connector includes a fixing part and a limiting part, the limiting part being used to engage with the hydraulic torque wrench, and the fixing part being used to securely connect with the hydraulic torque wrench.
[0007] Optionally, the fixing part is configured as a screw extending beyond the mounting member, the screw being used for threaded connection with the first threaded hole provided on the hydraulic torque wrench.
[0008] Optionally, the mounting component is constructed as a mounting rod, which has a second threaded hole. The screw is threadedly connected to the second threaded hole, with one end extending out of the mounting rod to be connected to the hydraulic torque wrench, and the other end located outside the mounting rod and connected to a knob.
[0009] Optionally, the limiting part is configured as a limiting pin disposed on the side of the fixing part, the limiting pin being used to engage with a plurality of limiting holes disposed circumferentially on the hydraulic torque wrench.

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0025] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the corresponding component in the direction of gravity when in use, while "inner" and "outer" refer to the inner and outer positions relative to the outline of the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.
[0026] This disclosure provides a safety fixture for a hydraulic torque wrench, comprising: a mounting part 2; a handheld part 3 disposed on the mounting part 2; and a connecting part 4 disposed on the mounting part 2 for detachable connection with the hydraulic torque wrench 1, the hydraulic torque wrench 1 being a professional bolt tightening tool that uses hydraulic power to provide high torque output for bolt installation and removal.
[0027] Through the above technical solution, the mounting component 2 is detachably connected to the hydraulic torque wrench 1 via the connector 4. It can be installed when needed and removed when not needed, reducing the space occupied by the hydraulic torque wrench 1 without hindering its normal use. The mounting component 2 is equipped with a handheld component 3. When using the hydraulic torque wrench 1 to perform torque testing, the operator can hold the handheld component 3 to fix the hydraulic torque wrench 1, without having to directly contact the hydraulic torque wrench 1 with bare hands, thus avoiding hand injury.
[0028] As an optional implementation method, such as Figure 2-3 As shown, the connector 4 includes a fixing part 41 and a limiting part 42. The limiting part 42 is used to engage with the hydraulic torque wrench 1, and the fixing part 41 is used to fasten the connection with the hydraulic torque wrench 1. The safety fixture is limited by the limiting part 42 and fastened by the fixing part 41, thereby connecting the installation work with the hydraulic torque wrench 1.
[0029] Optionally, such as Figure 2 and Figure 4 As shown, the fixing part 41 is constructed as a screw extending beyond the mounting part 2. The screw is used to thread into the first threaded hole 8 provided on the hydraulic torque wrench 1. The safety tool is installed on the hydraulic torque wrench 1 by threading the screw into the first threaded hole 8. The hydraulic torque wrench 1 itself is provided with the first threaded hole 8, which is used during the production or assembly of the hydraulic torque wrench 1. This disclosure utilizes the first threaded hole 8 provided on the hydraulic torque wrench 1 to install the safety tool without modifying the hydraulic torque wrench 1. The first threaded hole 8 is located on the opposite side of the working head of the hydraulic torque wrench 1, that is, on the upper surface of the hydraulic torque wrench 1 in the use state, which is convenient for the operator to hold. Of course, if some models of hydraulic torque wrench 1 do not have the first threaded hole 8, then it needs to be made separately.
[0030] Among them, such as Figure 2-3 As shown, the mounting component 2 is constructed as a mounting rod, which has a second threaded hole 7. A screw is threadedly connected to the second threaded hole 7, with one end extending beyond the mounting rod to connect to the hydraulic torque wrench 1. The other end is located outside the mounting rod and connected to a knob 5. By rotating the knob 5, the screw rotates and thus connects to the first threaded hole 8, without needing to rotate the handpiece 3 or the mounting component 2. The limiting part 42 can be used to limit the screw before rotating the knob 5, preventing the mounting component 2 from being unable to rotate due to the presence of the limiting part 42. In other embodiments, the screw can also be fixedly connected to the mounting component 2. During installation, rotating the mounting component 2 connects the screw to the first threaded hole 8. In this case, the limiting part 42 can be set to a telescopic type, extending and limiting the screw after the fixing part 41 is fixed.
[0031] Optionally, such as Figure 2 and Figure 4 As shown, the limiting part 42 is constructed as a limiting pin provided on the side of the fixing part 41. The limiting pin is used to insert into multiple limiting holes 9 arranged in a ring on the hydraulic torque wrench 1. For example, the limiting holes 9 are arranged around the outside of the first threaded hole 8. The mounting part 2 is positioned by inserting the limiting pin into the limiting holes 9. Multiple limiting holes 9 are provided in a ring, so the position and angle of the handpiece 3 can be adjusted for easier gripping. The hydraulic torque wrench 1 itself is provided with limiting holes 9, which have the same function as the first threaded hole 8. If some models of hydraulic torque wrench 1 do not have limiting holes 9, then they need to be made separately.
[0032] The mounting component 2 is provided with a mounting hole 6. The limit pin is detachably connected to the mounting hole 6, which facilitates the replacement of the limit pin and the adjustment of the position of the limit pin. The limit pin can be directly inserted into the mounting hole 6, or the mounting hole 6 can be set as a bolt hole. One end of the limit pin is provided with an external thread to be threadedly connected to the mounting hole 6.
[0033] Optionally, such as Figure 3 As shown, a plurality of mounting holes 6 are provided around the fixing part 41. Limiting pins can be selectively connected to the mounting holes 6. The number of limiting pins is less than or equal to the number of mounting holes 6. The number of limiting pins and the installation position can be selected, so that even if a mounting hole 6 is damaged, it can still be used normally. For example, in this disclosure, there are two limiting pins.
[0034] As an optional implementation method, such as Figure 1 As shown, the handheld part 3 is connected to the end of the mounting part 2 away from the hydraulic torque wrench 1, so that there is a certain distance between the handheld part 3 and the hydraulic torque wrench 1, leaving a gripping space, while avoiding contact between the operator's hand and the hydraulic torque wrench 1.
[0035] As an optional implementation method, such as Figure 1-2As shown, the handheld component 3 is set perpendicular to the mounting component 2, which facilitates the installation of the mounting component 2 and the gripping of the handheld component 3.
[0036] As an optional implementation method, such as Figure 2 As shown, the handheld part 3 is provided with anti-slip texture 10, such as stripes or mesh patterns. The anti-slip texture 10 can enhance the friction between the hand and the handheld part 3 and prevent slippage.
[0037] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
[0038] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0039] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
