Description

Technical Field

[0001] This invention relates to the technical field of electromechanical installation, and more particularly to a positioning and measuring device for electromechanical installation construction. Background Technology

[0002] Mechanical and electrical installation is a comprehensive engineering field that encompasses multiple professional sectors, including the installation of mechanical equipment, electrical systems, piping systems, and automated control systems in industrial and civil buildings. Its core function is to build a mechanical and electrical system with functions such as power, control, and transmission for buildings or industrial facilities. Fire pumps are essentially specialized power machinery and equipment, and their installation involves positioning and leveling the pump body, foundation pouring, and pipe connection. Pipe connection belongs to the water supply and drainage / fire protection piping subsystem. Water pipes are installed at the port of the fire pump. The fire pump and water pipes are usually connected by flanges or clamps. The core of the connection is to first position, then fine-tune, and finally fix.

[0003] The current method of connecting water pipes to fire pumps presents the following problems: The existing installation process requires two workers to cooperate. One worker needs to hold the water pipe for an extended period to align it with the fire pump's port before the other worker can connect them. This operation is complex and poses safety hazards. Furthermore, the water pipe connecting the fire pump is heavy, making alignment difficult. Therefore, a positioning and measuring device is designed to ensure alignment between the fire pump port and the water pipe's center, while also securing the pipe to be installed. This allows workers to easily and quickly install the water pipe to the fire pump, simplifying the entire process and reducing workload and difficulty. Moreover, this device can position and secure pipes of any diameter. Summary of the Invention

[0004] In view of the problems of complex operation and safety risks in the manual positioning and installation of fire pumps and water pipes in existing technologies, a positioning and measuring device for electromechanical installation construction is proposed.

[0005] This application provides a positioning and measuring device for electromechanical installation construction. Its purpose is to: by setting up an installation unit, the fixing component in the installation unit can quickly and accurately position the center of the fire pump port. At this time, the center of the moving cylinder is the center of the fire pump port. After positioning is completed, the entire device can be fixed inside the fire pump port. The water pipe to be installed is placed on the moving cylinder, and the fixing component quickly positions the water pipe to be installed and aligns and fixes it with the fire pump. The operator only needs to connect the two with flanges or clamps. The whole operation is simple, fast and easy.

[0006] The technical solution of the present invention is as follows: a positioning and measuring device for electromechanical installation construction, comprising a fixed cylinder, a connecting cylinder fixedly installed on the side wall of the fixed cylinder, and an installation unit disposed at the upper end of the fixed cylinder, wherein the installation unit includes a positioning component disposed between the fixed cylinder and the connecting cylinder; The positioning component includes a mounting plate disposed on the end of the fixed cylinder away from the connecting cylinder, a mounting groove formed on the upper end of the mounting plate, a moving cylinder slidably disposed on the outer wall of the connecting cylinder, a circular disc disposed on the outer wall of one end of the moving cylinder, a plurality of positioning rods one respectively hinged to the mounting groove, a plurality of positioning rods two respectively hinged to the outer wall of the circular disc, the ends of the plurality of positioning rods one away from the mounting groove are respectively hinged to the corresponding positioning rods two, and a driving assembly is installed between the fixed cylinder and the connecting cylinder; The drive assembly includes a telescopic cylinder disposed inside the fixed cylinder. A second transmission element is installed between the telescopic cylinder and the moving cylinder. The first positioning rod and the second positioning rod extend outward to fix the fixed cylinder inside the pipe wall of the fire pump. The moving cylinder can slide horizontally on the outer wall of the connecting cylinder.

[0007] Furthermore, the second transmission element includes a sliding groove on the outer wall of the moving cylinder, an intermediate plate slidably disposed on the inner wall of the moving cylinder, multiple driving plates disposed on the side wall of the intermediate plate, and a synchronization ring disposed between the outer walls of the multiple driving plates. The multiple driving plates slide inside the corresponding sliding groove, and a spring is installed between the synchronization ring and the circular disc.

[0008] Furthermore, the spring component includes a high-strength leaf spring disposed between the synchronizing ring and the circular disc, and a pull rod disposed on the telescopic end of the telescopic cylinder. The end of the pull rod away from the telescopic cylinder is fixedly connected to the side wall of the intermediate plate. The high-strength leaf spring only begins to deform when the intermediate plate is subjected to a large tensile force.

[0009] Furthermore, the installation unit also includes a fixing component for positioning and fixing the water pipe to be installed. The fixing component includes a bearing ring disposed on the outer wall of the moving cylinder, multiple bearing blocks disposed on the outer wall of the bearing ring, multiple sliding grooves II formed on the outer wall of the moving cylinder, a movable plate slidably disposed on the inner wall of the moving cylinder, and multiple mounting seats disposed on the outer wall of the movable plate. The multiple mounting seats are slidably installed inside the corresponding sliding grooves II. A limit component is installed between the mounting seat and the movable plate, and a connecting rod is disposed between the movable plate and the intermediate plate.

[0010] Furthermore, the limiting assembly includes a limiting rod one hinged to the bearing block and a limiting rod two hinged to the mounting base. The end of the limiting rod one away from the bearing block is hinged to the limiting rod two. An adjusting element is installed on the limiting rod one.

[0011] Furthermore, the adjusting element includes a shaft disposed on the outer wall of the limiting rod, and an adjusting wheel disposed on the outer wall of the shaft. The adjusting wheel contacts the inner wall of the pipe to be installed, ensuring that the pipe to be installed can move and adjust freely in the horizontal direction.

[0012] Furthermore, the positioning rod one, positioning rod two, limiting rod one, and limiting rod two are all made of steel with high hardness. The hinge point of the positioning rod one and the positioning rod two is fitted with a rubber ring to reduce rigid contact. A rubber ring is also fitted on the outer wall of the adjusting wheel.

[0013] Furthermore, a moving vehicle is installed on the side wall of both the fixed cylinder and the moving cylinder. In the initial state, the moving vehicle can drive the entire device to move horizontally along the inside of the pipe.

[0014] Furthermore, a pressure sensor is fixedly installed on the telescopic end of the telescopic cylinder.

[0015] The beneficial effects of this invention are: By setting up positioning components, workers place the fixed cylinder area inside the fire pump port, while the moving cylinder is located outside the port. Activating the telescopic cylinder causes positioning rod one and positioning rod two to expand outwards. Because they are hinged together, their hinge point expands outwards at equal distances. As the hinge point contacts and presses against the inner wall of the port, it drives the fixed cylinder to move synchronously. When the hinge point is completely pressed against the inner wall, the center of the fixed cylinder and the center of the port are on the same horizontal line, thus completing the positioning of the port center and simultaneously fixing the entire device at the fire pump port.

[0016] By setting fixed components, after the positioning component completes the positioning of the port center and the device is fixed, the worker roughly aligns the pipe to be installed with the port and places the moving cylinder on the inner wall of the pipe to be installed. During the continued movement of the telescopic cylinder, due to the limiting of the center plate by positioning rod one and positioning rod two, the pulling force of the telescopic cylinder can only act on the intermediate plate and the strong leaf spring. The intermediate plate and the moving cylinder move relative to each other. During the movement, the fixed rod two is pulled, causing the fixed rod two and the fixed rod one to also move outward. During the movement, they come into contact with and press against the pipe to be installed, thereby quickly positioning and fixing the water pipe to be installed. At the same time, because the rotating wheel squeezes against the inner wall of the pipe, the worker can also adjust the horizontal position of the pipe to make the pipe and the port fit tightly together, which is convenient for subsequent connection and installation.

[0017] By setting positioning rods and fixing rods to position and fix the fire pump and water pipe respectively, this device can be used for pipes and fire pump ports of any diameter, effectively improving the applicability of the device. By setting pressure sensors, the resistance encountered when the telescopic cylinder retracts can be obtained in real time, thereby accurately determining whether the positioning rods and fixing rods have been fixed and positioned, effectively improving the flexibility of the device. At the same time, mobile carts are set at both ends. After the pipeline installation is completed and the device is reset, the mobile carts come into contact with the pipeline and can move the device inside the pipeline and remove the device.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Example 1, referring to Figures 1-4The first embodiment of the present invention provides a positioning and measuring device for electromechanical installation construction, including a fixed cylinder 1, a connecting cylinder 2 fixedly installed on the side wall of the fixed cylinder 1, and an installation unit installed on the upper end of the fixed cylinder 1. The installation unit includes a positioning component installed between the fixed cylinder 1 and the connecting cylinder 2.

[0022] The positioning component includes a mounting plate 101 fixedly mounted on the end of the fixed cylinder 1 away from the connecting cylinder 2, a mounting groove formed on the upper end of the mounting plate 101, a moving cylinder 102 slidably mounted on the outer wall of the connecting cylinder 2, a circular disc 103 fixedly mounted on the outer wall of one end of the moving cylinder 102, a plurality of positioning rods 104 respectively hinged to the mounting groove, a plurality of positioning rods 105 respectively hinged to the outer wall of the circular disc 103, the ends of the plurality of positioning rods 104 away from the mounting groove are respectively hinged to the corresponding positioning rods 105, and a drive assembly is installed between the fixed cylinder 1 and the connecting cylinder 2.

[0023] The drive assembly includes a telescopic cylinder 201 fixedly installed inside the fixed cylinder 1. A second transmission element is installed between the telescopic cylinder 201 and the moving cylinder 102. Positioning rod 104 and positioning rod 105 fix the fixed cylinder 1 to the pipe wall of the fire pump by extending outward. The moving cylinder 102 can slide horizontally on the outer wall of the connecting cylinder 2.

[0024] Specifically, the positioning component functions as follows: by extending outwards at equal intervals with multiple positioning rods 104 and 105, when their hinge points come into contact with the inner wall of the fire pump port, the center of the connecting cylinder 2 and the center of the fire pump are at the same position. As the multiple positioning rods 104 and 105 extend outwards, they fix the entire device inside the port, facilitating subsequent positioning and installation. By setting a second transmission element, this device can complete the positioning alignment and fixing between the fire pump port and the pipeline by setting a telescopic cylinder 201, thereby enabling workers to quickly install and fix the water pipe and the fire pump port.

[0025] The second transmission element includes a sliding groove 202 formed on the outer wall of the moving cylinder 102, an intermediate plate 203 slidably mounted on the inner wall of the moving cylinder 102, multiple driving plates 204 fixedly mounted on the side wall of the intermediate plate 203, and a synchronization ring 205 fixedly mounted between the outer walls of the multiple driving plates 204. All driving plates 204 slide within their respective sliding grooves 202. A spring is installed between the synchronization ring 205 and the circular disc 103. The spring includes a high-strength leaf spring 206 fixedly mounted between the synchronization ring 205 and the circular disc 103, and a pull rod 207 fixedly mounted on the telescopic end of the telescopic cylinder 201. The end of the pull rod 207 away from the telescopic cylinder 201 is fixedly connected to the side wall of the intermediate plate 203. The high-strength leaf spring 206 only begins to deform when the intermediate plate 203 is subjected to a large tensile force.

[0026] Specifically, the second transmission element is the second state of this device. The first state is as follows: when the telescopic cylinder 201 retracts, it generates a pulling force on the intermediate plate 203. The intermediate plate 203 transmits this force to the synchronous ring 205 through the driving plate 204. At this time, the moving cylinder 102 can slide freely in the horizontal direction. Therefore, after the synchronous ring 205 is pulled, it will drive the entire moving cylinder 102 to move in the horizontal direction. When the moving cylinder 102 moves, it drives the circular disk 103 on its outer wall to move in the direction of the pulling force, thereby driving one end of the positioning rod 105 to move synchronously. During the movement of the positioning rod 105, the hinge point between the positioning rod 105 and the positioning rod 104 rotates, and during the rotation... During the movement, the hinge point of both expands outward. As the positioning rod 104 and positioning rod 105 move, the hinge point of both is pressed tightly against the inner wall of the fire pump port. During the pressing process, the following changes occur: As the hinge point of both is pressed tightly, the positioning rods (i.e., positioning rod 104 and positioning rod 105, hereinafter collectively referred to as positioning rods) expand outward (similar to an umbrella), causing the fixed cylinder 1 to move until the hinge point is pressed tightly. At this time, multiple positioning rods fix the fixed cylinder 1 at the fire pump port, and the center of the fixed cylinder 1 is at the same position as the center of the port. Therefore, the positioning of the center of the fire pump port is completed.

[0027] When the hinge of the positioning rod is in close contact with the inner wall of the port, the telescopic cylinder 201 continues to move, and is in the second state. The second state is: after the hinge point is in close contact, the positioning rod limits the circular disk 103 in the horizontal direction. Therefore, the tension generated by the telescopic cylinder 201 on the intermediate plate 203 directly acts on the strong leaf spring 206, causing the strong leaf spring 206 to deform. At the same time, the synchronizing ring 205 and the moving cylinder 102 move relative to each other, which causes the synchronizing ring 205 to slide horizontally inside the sliding groove 202, thereby triggering the subsequent installation unit.

[0028] The second transmission element cooperates with the spring component, enabling the telescopic cylinder 201 to control the clamping component and the fixing component in stages. This allows the clamping component to fix the entire device while simultaneously fixing the entire device at the port of the fire pump, and the fixing component to fix the pipe to be installed on the outer wall of the moving cylinder 102, as well as to quickly position the center of the pipe to be installed.

[0029] During use, the operator places the fixed cylinder 1 inside the port of the fire pump, while the moving cylinder 102 is located outside the port. At this time, the telescopic cylinder 201 is activated. The telescopic end of the telescopic cylinder 201 generates a pulling force on the intermediate plate 203 via the pull rod 207. The intermediate plate 203 transmits this pulling force to the moving cylinder 102 via the driving plate 204 and the synchronizing ring 205. The moving cylinder 102 can then slide freely in the horizontal direction. Therefore, when the moving cylinder 102 is subjected to tension, it moves horizontally and synchronously drives the circular disc 103 on the outer wall to move. During the movement of disc 103, one end of positioning rod 105 moves horizontally in sync, causing the hinge point between positioning rod 104 and positioning rod 105 to deflect. As positioning rod 105 moves, the hinge point continues to expand outward at equal distances. During the expansion of the hinge point, the position of fixed cylinder 1 changes. When the hinge point is in close contact with the inner wall of the fire pump port, the fixed cylinder 1 is firmly fixed inside the fire pump pipe wall by the positioning rod. At the same time, the center of fixed cylinder 1 coincides with the center of the fire pump port, thus completing the positioning of the port center.

[0030] When the hinge points come into contact, the second state is triggered. As the telescopic cylinder 201 continues to retract, the horizontal movement of the moving cylinder 102 is limited by the positioning rod. Therefore, the tension on the synchronizing ring 205 directly acts on the strong leaf spring 206, causing the strong leaf spring 206 to deform. During the deformation, the synchronizing ring 205 and the moving cylinder 102 move relative to each other. The synchronizing ring 205 moves relative to each other inside the sliding groove 202, thereby triggering the subsequent fixing components.

[0031] Example 2, refer to Figures 5-8This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the installation unit further includes a fixing component, which is used to position and fix the water pipe to be installed. The fixing component includes a bearing ring 301 fixedly installed on the outer wall of the moving cylinder 102, a plurality of bearing blocks 302 fixedly installed on the outer wall of the bearing ring 301, a plurality of sliding grooves 303 formed on the outer wall of the moving cylinder 102, a movable plate 304 slidably installed on the inner wall of the moving cylinder 102, a plurality of mounting seats 305 fixedly installed on the outer wall of the movable plate 304, and the plurality of mounting seats 305 are all slidably installed inside the corresponding sliding grooves 303. A limit component is installed between the mounting seat 305 and the movable plate 304, and a connecting rod 306 is fixedly installed between the movable plate 304 and the intermediate plate 203. The limiting assembly includes a first limiting rod 401 hinged to the support block 302 and a second limiting rod 402 hinged to the mounting base 305. The end of the first limiting rod 401 away from the support block 302 is hinged to the second limiting rod 402. An adjusting element is installed on the first limiting rod 401. The adjusting element includes a shaft 403 fixedly installed on the outer wall of the first limiting rod 401 and an adjusting wheel 404 rotatably installed on the outer wall of the shaft 403. The adjusting wheel 404 contacts the inner wall of the pipe to be installed, ensuring that the pipe to be installed can move and adjust freely in the horizontal direction.

[0032] Positioning rod 104, positioning rod 2 105, limiting rod 1 401 and limiting rod 2 402 are all made of high-hardness steel. The hinge point of positioning rod 104 and positioning rod 2 105 is fitted with a rubber ring to reduce rigid contact. A rubber ring is also fitted on the outer wall of adjusting wheel 404.

[0033] Specifically, the positioning component is used to position and vertically fix the pipe to be installed. After the positioning component completes the center positioning of the fire pump port, the operator can place the pipe to be installed on one side of the port, with the moving cylinder 102 located inside the pipe. At this time, the telescopic cylinder 201 continues to move, driving the intermediate plate 203 to move horizontally relative to the moving cylinder 102. During the movement, the connecting rod 306 pulls the moving plate 304 to move synchronously. During the movement of the moving plate 304, the mounting base 305 pulls one end of the limiting rod 402 to move synchronously. At this time, the movement trajectory and principle of limit rod 1 401 and limit rod 2 402 are the same as those of the positioning rod. When the adjusting wheel 404 at the hinge point of the two contacts and squeezes the inside of the pipe, limit rod 2 402 limits the movement of the moving plate 304 and prevents it from moving. At this time, the limit rod fixes the pipe to be installed, and the pipe and the port of the fire pump are at the same horizontal position. The staff can push the pipe so that the pipe can move horizontally under the action of the adjusting wheel 404, thereby ensuring that after the pipe is positioned, the side wall of the pipe and the side wall of the port of the fire pump are tightly attached to each other.

[0034] The remaining structure is the same as that in Example 1.

[0035] Example 3, referring to Figure 1 This is the third embodiment of the present invention, which differs from the second embodiment in that: a moving trolley (not shown in the figure) is installed on the side wall of both the fixed cylinder 1 and the moving cylinder 102. In the initial state, the moving trolley can drive the entire device to move horizontally along the inside of the pipe. A pressure sensor (not shown in the figure) is fixedly installed on the telescopic end of the telescopic cylinder 201.

[0036] Specifically, the mobile cart is used to move the device inside the pipeline. In the initial state, the wheels of the mobile cart can contact the inner wall of the pipeline. When the positioning rod and the limiting rod are in the outward expansion state, the mobile cart is in the air. Therefore, the mobile cart will not affect the normal operation of the device. When the device has completed its work, the entire device is inside the pipeline. At this time, the staff can control the mobile cart to move the device horizontally inside the pipeline to the pipeline port through the controller (not shown in the figure), which is convenient for the staff to retrieve it.

[0037] The pressure sensor at the upper end of the telescopic cylinder 201 is used to monitor the resistance encountered when its telescopic end retracts in real time. If the telescopic cylinder 201 encounters resistance during the retraction process (meaning that the hinge point of the limit rod is in close contact with the inner wall of the pipe and the telescopic cylinder 201 cannot continue to retract normally), the controller will close the telescopic cylinder 201 to prevent the device from being damaged or deformed due to excessive tension, thus protecting the device and the pipeline.

[0038] The remaining structure is the same as that in Example 2.

[0039] Based on embodiments 1-3, the working principle of the present invention is as follows: The operator places the fixed cylinder 1 inside the port of the fire pump, while the moving cylinder 102 is located outside the port. At this time, the telescopic cylinder 201 is activated. The telescopic end of the telescopic cylinder 201 generates a pulling force on the intermediate plate 203 via the pull rod 207. The intermediate plate 203 transmits this pulling force to the moving cylinder 102 via the driving plate 204 and the synchronizing ring 205. At this time, the moving cylinder 102 can slide freely in the horizontal direction. Therefore, when the moving cylinder 102 is subjected to a pulling force, it moves horizontally and drives the circular disc 103 on the outer wall. During synchronous movement, the circular disk 103 drives one end of the positioning rod 105 to move horizontally, causing the hinge point between the positioning rod 104 and the positioning rod 105 to deflect. As the positioning rod 105 moves, the connected hinge point continuously expands outward at equal distances. During the expansion of the hinge point, the position of the fixed cylinder 1 changes. When the hinge point is in close contact with the inner wall of the fire pump port, the fixed cylinder 1 is firmly fixed inside the fire pump pipe wall by the positioning rod. At the same time, the center of the fixed cylinder 1 coincides with the center of the fire pump port, thus completing the positioning of the port center.

[0040] When the hinge points come into contact, the second state is triggered, and the telescopic cylinder 201 continues to retract. At this time, because the horizontal movement of the moving cylinder 102 is limited by the positioning rod, the tension on the synchronizing ring 205 directly acts on the strong leaf spring 206, causing the strong leaf spring 206 to deform. The telescopic cylinder 201 continues to move, driving the intermediate plate 203 to move horizontally relative to the moving cylinder 102. During this movement, the connecting rod 306 pulls the moving plate 304 to move synchronously. During the movement of the moving plate 304, the mounting base 305 pulls one end of the limiting rod 402 to move synchronously. At this time, the limiting rod... The movement trajectory and principle of limit rod 401 and limit rod 402 are the same as those of the positioning rod. When the adjusting wheel 404 at the hinge point of the two contacts and squeezes the inside of the pipe, the limit rod 402 limits the movement of the moving plate 304 and prevents it from moving. At this time, the limit rod fixes the pipe to be installed. At this time, the pipe and the port of the fire pump are at the same horizontal position. The workers can push the pipe so that it can move horizontally under the action of the adjusting wheel 404. This ensures that after the pipe is positioned, the side wall of the pipe and the side wall of the fire pump port are tightly attached to each other. After they are tightly attached, the workers can make flange connections or clamp connections between the two.

[0041] After installation, the telescopic cylinder 201 is reset. At this time, both the positioning rod and the limit rod are reset. After the reset, the wheels of the moving vehicle are in contact with the inner wall of the pipe. The moving vehicle is then activated, causing it to move the entire device inside the pipe. After moving to the pipe end, the operation is repeated to position and fix the next section of the pipe, thereby achieving direct and rapid positioning and installation of the pipe.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
