Description

Technical Field

[0001] This utility model relates to the field of installation tool technology, specifically a special tool for installing TSI probes. Background Technology

[0002] The working space where TSI probes are installed is usually quite small. When using a traditional wrench to tighten the nuts, the limited range of motion necessitates repeated adjustments of the wrench position and gradual tightening at small angles, which is inconvenient. Furthermore, the nuts should not be tightened too much during the installation of TSI probes. It is best to leave them within a certain number of turns to balance the installation's stability with component protection. This prevents damage to insulation, changes in clearance, or damage to the threads caused by excessive tightening, thus ensuring the long-term stability of the measurement system.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6The TSI probe installation tool provided by this utility model includes: a handle 1 and a housing 2 installed on one side of the outer wall of the handle 1. It also includes: an active shaft 3 and a driven shaft 4 rotatably installed on both ends of the inner wall of the housing 2. Two transmission components 5 are installed on the outer wall of the active shaft 3, and the active shaft 3 is connected to the driven shaft 4 through the two transmission components 5. A drive gear 6 is fixed on the outer wall of the driven shaft 4, and a cam 8 is installed on one end of the active shaft 3. A pressing component 9 is installed on one side of the outer wall of the housing 2, and a pressing counter 10 is installed on one side of the outer wall of the housing 2. L-shaped rods 11 are installed on both the upper and lower outer walls of one end of the housing 2, and a ball 12 is installed on one end of the L-shaped rod 11. A rotating ring 13 is provided at one end of the housing 2, and the inner wall of the rotating ring 13 is a regular hexagonal structure. Multiple equally spaced toothed grooves 14 are opened on the outer wall of the rotating ring 13, and annular grooves 15 are opened at both ends of the outer wall of the rotating ring 13. The ball 12 is placed in the annular groove 15, and the ball 12 and the inner wall of the annular groove 15 form a sliding fit.

[0021] It should be noted here that: handle 1 provides a gripping fulcrum for the operator, and housing 2 serves as the mounting carrier for internal components. Its compact structure allows it to be easily inserted into narrow spaces where TSI probes are installed (such as turbine cylinder gaps, equipment interlayers, etc.), solving the problem of limited space in traditional wrenches.

[0022] The drive shaft 3 and the driven shaft 4 are connected by two transmission components 5. When the drive shaft 3 is rotated, the power is transmitted to the driven shaft 4 through the transmission components 5, which drives the drive gear 6 on the driven shaft 4 to rotate synchronously.

[0023] The drive gear 6 meshes with the tooth groove 14 on the outer wall of the rotating ring 13. Therefore, when the drive gear 6 rotates, it will drive the rotating ring 13 to rotate. Since the inner wall of the rotating ring 13 is a regular hexagonal structure, it can be tightly fitted on the outside of the mounting nut of the TSI probe. Thus, the nut can be directly turned by rotating the rotating ring 13, realizing continuous turning in a narrow space (without repeatedly adjusting the tool position).

[0024] The ball 12 at the end of the L-shaped rod 11 on the housing 2 is embedded in the annular groove 15 of the rotating ring 13. The ball 12 and the annular groove 15 are in sliding fit, which provides radial support for the rotating ring 13 to ensure its stable rotation, and does not hinder the circumferential movement of the rotating ring 13.

[0025] The cam 8 at one end of the drive shaft 3 rotates synchronously with the drive shaft 3. When the cam 8 rotates, it pushes the pressing component 9, causing the pressing component 9 to reciprocate. This causes the pressing counter 10 to be pressed once per cycle, thereby realizing real-time counting of the number of rotations of the nut and meeting the requirement of the TSI probe that "the number of nut tightening turns must be controlled within a certain range".

[0026] In a preferred embodiment, the transmission assembly 5 includes a drive gear 501 mounted on the outer wall of the drive shaft 3, a driven gear 502 mounted on the outer wall of the driven shaft 4, and a toothed belt 503 that drives the drive gear 501 and the driven gear 502.

[0027] It should be noted here that: the drive gear 501 is fixed to the outer wall of the drive shaft 3 and rotates synchronously with the rotation of the drive shaft 3. Its teeth mesh with the inner tooth groove of the toothed belt 503, transmitting the rotational power to the toothed belt.

[0028] Since the toothed belt 503 is a tensile toothed belt with high tensile strength, it will not deform due to tension under the driving force of the drive gear 501, and can maintain the stability of tooth profile accuracy and transmission length, ensuring that power is efficiently transmitted to the driven gear 502.

[0029] Driven gear 502 is fixed to the outer wall of driven shaft 4. Its teeth mesh with the tooth groove on the other side of toothed belt 503. It receives the power transmitted by toothed belt 503 and rotates synchronously with toothed belt 503, thereby driving driven shaft 4 to rotate.

[0030] In a preferred embodiment, the pressing assembly 9 includes a mounting plate 901, a movable rod 902 movably inserted into the outer wall of one side of the mounting plate 901, a spring 903 sleeved on the outside of the movable rod 902, and a pressing block 904 installed at one end of the movable rod 902; one end of the movable rod 902 contacts the outer wall of the cam 8.

[0031] It should be noted here that when the cam 8 rotates with the drive shaft 3, the protruding part of the cam 8 will push the movable rod 902 to move towards the push-type counter 10, so that the push block 904 presses the counter.

[0032] When the protruding part of the cam 8 rotates past the movable rod 902, the spring 903, due to the elastic force generated by the pressure, will push the movable rod 902 to reset, waiting for the cam 8 to push again, forming a reciprocating motion to achieve periodic counting.

[0033] In a preferred embodiment, a rotating handle 7 is mounted on one end of the drive shaft 3, and the outer wall of the rotating handle 7 is provided with anti-slip texture.

[0034] It should be noted here that this facilitates the rotation of the drive shaft 3.

[0035] In a preferred embodiment, the drive gear 6 meshes with the tooth groove 14 on the outer wall of the rotating ring 13, and the ratio of the number of teeth of the drive gear 6 to the number of tooth grooves 14 is 1:3.

[0036] It should be noted here that: the drive gear 6 meshes with the tooth groove 14 of the rotating ring 13. When the drive gear 6 rotates, it drives the rotating ring 13 to rotate through the inter-tooth meshing.

[0037] Since the ratio of the number of teeth of the drive gear 6 to the number of tooth grooves 14 is 1:3, the rotating ring 13 rotates once for every 3 rotations of the drive gear 6. This speed reduction transmission design can achieve fine tightening of the nut at small angles, and at the same time, it is convenient to calculate the number of rotations of the rotating ring 13, and thus obtain the number of rotations of the nut.

[0038] Working principle: This tool solves the operational challenge of installing TSI probe nuts in confined spaces through a coordinated design of mechanical transmission, spatial adaptation, and turn counting, while simultaneously achieving precise control over the number of turns. The specific principle is as follows:

[0039] Space adaptation and grip basics

[0040] Handle 1 provides the operator with a stable grip fulcrum, making it easy to apply rotational force;

[0041] The housing 2 serves as the mounting carrier for internal components and features a compact design that allows it to easily reach into narrow spaces where TSI probes are installed, such as turbine cylinder gaps and equipment interlayers, avoiding the problem of traditional wrenches being too large to operate.

[0042] Power transmission and nut tightening

[0043] The operator can rotate the handle 7 at one end of the drive shaft 3 to prevent slippage by turning the anti-slip texture on the outer wall of the handle, thereby driving the drive shaft 3 to rotate.

[0044] The drive shaft 3 transmits power to the driven shaft 4 through two transmission components 5. The drive gear 501 rotates with the drive shaft 3 and transmits power to the toothed belt 503 through meshing with it.

[0045] The toothed belt 503 is a tensile toothed belt with strong resistance to deformation, ensuring stable power transmission to the driven gear 502;

[0046] After receiving power, the driven gear 502 drives the driven shaft 4 to rotate synchronously;

[0047] The drive gear 6 on the driven shaft 4 rotates with the shaft and drives the rotating ring 13 to rotate by meshing with the tooth groove 14 on the outer wall of the rotating ring 13.

[0048] The inner wall of the rotating ring 13 is a regular hexagonal structure, which can be tightly fitted onto the outside of the mounting nut of the TSI probe. Therefore, its rotation can directly turn the nut, enabling continuous operation in a narrow space without repeatedly adjusting the tool position.

[0049] The ball 12 at the end of the L-shaped rod 11 on the housing 2 is embedded in the annular groove 15 of the rotating ring 13, which provides radial support for the rotating ring 13 without hindering its circumferential rotation, thus ensuring the stability of the twisting.

[0050] lap count and precise control

[0051] When the drive shaft 3 rotates, the cam 8 at one end of it rotates synchronously;

[0052] The protruding part of the cam 8 pushes the movable rod 902 of the pressing assembly 9, and the movable rod 902 moves axially along the mounting plate 901, driving the pressing block 904 to press the pressing counter 10 on the housing 2;

[0053] After the cam 8 protrusion rotates past the movable rod 902, the elastic force of the spring 903 pushes the movable rod 902 to return to its original position, waiting for the next press, forming a periodic reciprocating motion;

[0054] Each time the push-type counter 10 is pressed, it records one rotation of the drive shaft 3, thus enabling real-time monitoring of the number of turns the nut has made.

[0055] Reduction transmission and precision operation

[0056] The ratio of the number of teeth in the tooth groove 14 of the drive gear 6 to that of the rotating ring 13 is 1:3. That is, when the drive gear 6 rotates 3 times, the rotating ring 13 rotates only 1 time. The inner wall of the rotating ring 13 is a regular hexagonal structure and is fitted on the outside of the nut. Therefore, when the rotating ring 13 rotates 1 time, it drives the nut to rotate 1 time synchronously.

[0057] This deceleration design enables precise tightening of the nut at small angles, meeting the requirements of the TSI probe that "the nut should not be too tight and the number of turns should be controlled," while also reducing the difficulty of operation in confined spaces.

[0058] Through the synergistic effect of the above structures, the tool can efficiently tighten the nut in a confined space, and precisely control the number of turns, balancing installation stability and component protection, thus ensuring the long-term stability of the TSI probe measurement system.

[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
