Description

Technical Field

[0001] The utility model relates to the technical field of sensor disassembly and assembly, and more specifically, to a quick disassembly and assembly device for a portable pressure sensor. Background Art

[0002] When installing a pressure sensor in a hydropower plant, the pressure sensor is usually installed at the end of multiple pressure pipes. The multiple pressure pipes are connected by threads, and the pressure sensor is also connected to the end pressure pipe by threads. Moreover, waterproof treatment is required for each pipeline thread connection. When disassembling and assembling the pressure sensor, turning the pressure sensor often drives the multiple pressure pipes at the bottom to rotate synchronously. When disassembling the pressure sensor, the connections between the multiple pressure pipes at the bottom are prone to looseness, resulting in damage and failure of the waterproof seal and causing pipeline leakage. When installing the sensor, the multiple pressure pipes at the bottom are prone to be twisted and deformed due to lack of fixation. Therefore, during disassembly and assembly, usually one maintenance worker uses a wrench to fix the lower pressure pipe, and another maintenance worker uses another wrench to disassemble and assemble the pressure sensor, and the disassembly and assembly process is rather inconvenient.

[0028] The following provides a detailed description of the present utility model.

[0029] As Figures 1 - 5 shown:

[0030] A quick disassembly and assembly device for a portable pressure sensor, comprising a holding member 103, a clamping and fixing member 106 connected to one end of the holding member 103, a rotating member 105 disposed on the same side as the clamping and fixing member 106 and above the clamping and fixing member 106, and a rotation driving mechanism 107 installed on the holding member 103 and used to control the rotation of the rotating member 105 around the axis of the pressure pipe 101; the rotating member 105 and the clamping and fixing member 106 are coaxially arranged.

[0031] When in use, first, the clamping and fixing member 106 is sleeved on the outside of the pressure pipe 101 to make it engage and cooperate with the pressure pipe 101; then, the rotating member 105 is sleeved on the outside of the threaded portion of the pressure sensor 102 and connected to the rotation driving mechanism 107; then, the rotation driving mechanism 107 is used to control the rotating member 105 to rotate around the axis of the pressure pipe 101, thereby driving the pressure sensor 102 to rotate. Due to the setting of the clamping and fixing member 106, when the pressure sensor 102 rotates, the pressure pipe 101 will remain stationary and will not follow, thus realizing the disassembly and assembly of the pressure sensor 102.

[0032] Compared with the prior art, only one maintenance personnel is required for disassembly and assembly; during the disassembly and assembly process, the maintenance personnel do not need to exert force to twist the pressure sensor 102, which saves time and effort, greatly improves work efficiency, and the disassembly and assembly are simple and convenient.

[0033] In some possible implementation manners, a connecting member 104 is further provided at the end of the holding member 103;

[0034] The connecting member 104 includes a connecting body 104a detachably connected to the clamping and fixing member 106, and a sliding cooperation portion 104b installed on the side of the connecting body 104a away from the holding member 103 and slidably cooperating with the rotating member 105;

[0035] The sliding cooperation portion 104b is used for the installation of the rotating member 105 and to realize the sliding cooperation between the holding member 103 and the rotating member 105. The connecting body 104a is used to realize the detachable connection with the clamping and fixing member 106, thereby realizing the disassembly and assembly of pressure pipes 101 and pressure sensors 102 of different sizes.

[0036] In some possible implementation manners, the sliding cooperation portion 104b includes a mounting portion connected to the connecting body 104a and having an arc-shaped groove provided on the side away from the holding member 103; the rotating member 105 is installed in the arc-shaped groove and slidably cooperates with the mounting portion;

[0037] The rotating member 105 is rotatably installed in the arc-shaped groove; under the drive of the rotation drive mechanism 107, the rotating member 105 rotates around the axis of the pressure pipe 101.

[0038] In some possible embodiments, the rotation drive mechanism 107 includes a bevel gear disc 105c connected to the rotating member 105 and in the shape of a circular ring, a bevel gear 107c meshing with the bevel gear disc 105c, and a drive motor 107a installed in the holding member 103 and coaxially connected to the bevel gear 107c.

[0039] Furthermore, an installation cavity with an opening is provided in the holding member 103. The drive motor 107a is installed in the installation cavity, and the opening is closed by an end cover 103a. The setting of the end cover 103a enables the maintenance and replacement of the drive motor 107a. A transmission rod 107b connected to the output shaft of the drive motor 107a passes through the holding member 103 and is coaxially connected to the bevel gear 107c, driving the bevel gear 107c to rotate, so that the bevel gear disc 105c rotates around the axis of the pressure pipe 101, driving the rotating member 105 to rotate, and realizing the disassembly and assembly of the pressure sensor 102; during disassembly and installation, the rotation direction of the bevel gear 107c is opposite, and the axial direction of the transmission rod 107b is perpendicular to the axial direction of the pressure pipe 101.

[0040] In some possible embodiments, as Figure 2 , Figure 4 shown, the rotating member 105 is in the shape of a disc and is adapted to the arc-shaped groove; the rotating member 105 includes two sets of identical structures and engaging blocks that cooperate with each other inside to form a clamping groove 105d; the two sets of engaging blocks are installed on the bevel gear disc 105c;

[0041] The two sets of engaging blocks include a first engaging block 105a and a second engaging block 105b that are identical in structure and in the shape of a semi-circle. Among them, the first engaging block 105a is located in the arc-shaped groove; the mutually approaching sides of the first engaging block 105a and the second engaging block 105b cooperate to form the clamping groove 105d;

[0042] Preferably, the formed clamping groove 105d is a regular hexagon and is adapted to the outer contour of the screwed part on the outside of the pressure sensor 102;

[0043] During disassembly and assembly, different rotating members 105 can be selected for cooperation according to the outer contour shape of the screwed part of the pressure sensor 102;

[0044] As Figure 3 shown, an opening groove 106d is provided on the clamping and fixing member 106, and the clamping groove 105d is coaxially arranged with the bevel gear disc 105c; the opening groove 106d is clamped on the outside of the pressure pipe 101 and the two are in interference fit.

[0045] In some possible embodiments, such as Figure 2 shown, the sliding fit portion 104b further includes an arc rod 104c that slidably fits with the mounting portion and whose center is on the axis of the arc groove, and an auxiliary positioning block 104d that is connected to the end of the arc rod 104c and whose inner side is arc-shaped; the inner side of the auxiliary positioning block 104d and the bottom surface of the arc groove are on the same circumference;

[0046] The arc rod 104c can slide circumferentially around the smooth groove; the arc rod 104c is arranged inside the mounting portion and penetrates through the mounting portion at both ends. The arc rod 104c slidably fits with the mounting portion, and auxiliary positioning blocks 104d are respectively arranged at both ends of the arc rod 104c. The arc groove and the two groups of auxiliary positioning blocks 104d will cooperate to form an arc chamber, and the first clamping block 105a will be located inside the arc chamber;

[0047] such as Figure 2 shown, the length of the arc formed by the projection of the inner side of the arc groove and the auxiliary positioning block 104d is A, and the circumference of the outer circle of the rotating member 105 is B, with the setting of A > 0.5B; this will enable the two groups of auxiliary positioning blocks 104d to also be sleeved on the outside of the second clamping block 105b, making the connection between the two groups of clamping blocks and the mounting portion more stable; through the sliding fit between the arc rod 104c and the mounting portion, the disassembly of the two groups of clamping blocks is realized;

[0048] In some possible embodiments, in order to guide the sliding direction of the rotating member 105 with respect to the mounting portion; such as Figure 4 shown, a chute 105e coaxial with it is arranged on the outer side surface of the rotating member 105, and sliders that slidably fit with the chute 105e are respectively arranged on the inner side surface of the auxiliary positioning block 104d and the bottom surface of the arc groove; the chute 105e is a T-shaped groove or a dovetail groove, and the slider is the chute 105e to prevent falling off during the disassembly and assembly process;

[0049] The chute 105e can be arranged in multiple groups; semi-circular grooves are arranged on the outer side surfaces of the first clamping block 105a and the second clamping block 105b, and the two groups of grooves will communicate to form the chute 105e.

[0050] In some possible embodiments, in order to effectively achieve the disassembly and assembly of the clamping and fixing component 106; the clamping and fixing component 106 includes a clamping plate 106b provided with an opening groove 106d and in interference fit with the pressure pipe 101, a sliding rod 106a connected to the clamping plate 106b and in sliding fit with the connecting body 104a along the axial direction of the pressure pipe, and a limiting block 106c fixedly connected to the end of the sliding rod 106a away from the clamping plate 106b; the sliding rod 106a is arranged on the side of the clamping plate 106b away from the opening of the opening groove 106d; a vertical groove 104e with a long direction parallel to the axial direction of the pressure pipe and a disassembly and assembly groove 104f communicated with one end of the vertical groove 104e are arranged on the connecting body 104a; during assembly, first, the limiting block 106c is passed through the disassembly and assembly groove 104f, and then the sliding rod 106a is located in the vertical groove 104e, and vice versa for disassembly.

[0051] Specifically, during use, the maintenance personnel first move the clamping plate 106b up and down so that the clamping plate 106b can clamp the bolt part on the outer side of the pressure pipe 101 and be in interference fit, thereby preventing the pressure pipe 101 from rotating when the pressure sensor 102 is disassembled and assembled subsequently.

[0052] Then, the first clamping block 105a is clamped at the bolt position on the outer side of the pressure sensor 102, and the second clamping block 105b is spliced with the first clamping block 105a. After the splicing is completed, the maintenance personnel push the auxiliary positioning block 104d so that the auxiliary positioning block 104d extends outwards to wrap around the second clamping block 105b. After the wrapping is completed, the second clamping block 105b is connected to the first clamping block 105a, and under the wrapping action of the auxiliary positioning block 104d, the second clamping block 105b and the first clamping block 105a will not separate, as shown in the appendix Figure 2 as shown.

[0053] When disassembling and assembling the pressure sensor 102, the driving motor 107a is started. The driving motor 107a drives the bevel gear 107c to rotate through a transmission rod 107b connected to the output shaft. The bevel gear 107c meshes with the bevel teeth, so that the bevel gear 107c drives the bevel gear disk 105c to rotate, that is, the first clamping block 105a and the second clamping block 105b rotate. During the rotation process, the disassembly and assembly work of the pressure sensor 102 can be carried out.

[0054] In summary, through the mutual cooperation of the holding member 103, the connecting member 104, the rotating member 105, the clamping and fixing member 106, and the rotation driving mechanism 107, when it is necessary to disassemble and assemble the pressure sensor 102, the pressure pipe 101 can be limited by the clamping plate 106b, so as to prevent the pressure pipe 101 from rotating along with it, resulting in loosening or deformation of the pressure pipe 101. By the forward and reverse rotation of the driving motor 107a, the pressure sensor 102 can be rotated forward and backward, so as to disassemble and assemble the pressure sensor 102. The disassembly and assembly process is simple and convenient.

[0055] In addition, for different models of the pressure sensor 102 and the pressure pipe 101, the first clamping block 105a, the second clamping block 105b and the clamping plate 106b of different models can be replaced.

[0056] The replacement process is as follows: move the clamping plate 106b down to the bottom end of the vertical groove 104e, so that the disassembly and assembly groove 104f is aligned with the limiting block 106c, and the clamping plate 106b can be separated from the connecting body 104a, thus completing the replacement.

[0057] When disassembling the two groups of clamping blocks, the maintenance personnel move the auxiliary positioning block 104d to make one group of auxiliary positioning blocks 104d fit with the installation part. At this time, the first clamping block 105a and the second clamping block 105b can be separated, and the first clamping block 105a is rotated half a circle, and the first clamping block 105a can be separated from the installation part, thus completing the disassembly of the first clamping block 105a and the second clamping block 105b. Subsequently, the first clamping block 105a and the second clamping block 105b of different models can be replaced.

[0058] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
