Description

Technical Field

[0001] The present invention relates to engineering construction equipment, in particular to a fire protection pipeline installation device for building construction. Background Art

[0002] Firefighting pipes are specialized piping materials used to transport firefighting water or media. They are pressure-resistant, corrosion-resistant, and heat-resistant, and are typically painted red. Primary materials include ductile iron, galvanized steel, stainless steel, alloys, composites, and plastics. Installing firefighting pipes is a critical step in ensuring building fire safety, involving numerous specialized processes such as cutting, connecting, forming, securing, and testing.

[0003] Among them, when connecting fire-fighting pipes, the mainstream connection method is to splice two sections of fire-fighting pipes and fix them with threads or clamps.

DETAILED DESCRIPTION

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0047] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0048] The present invention relates to a fire protection pipe installation device for building construction, which is an auxiliary installation device suitable for assisting the installation of two unconnected fire protection pipes, thereby improving the installation efficiency of the fire protection pipes. Of course, the device is not limited to fire protection pipes, and is also applicable to the auxiliary splicing of other large pipes.

[0049] The present invention will be further described in detail below with reference to the accompanying drawings.

[0050] Figure 1 The figure schematically shows a fire protection pipe installation device for building construction according to an embodiment of the present invention. Figure 1 As shown, the building fire protection pipe installation device includes a base 3, a first clamping component 1, a second clamping component 2 and a positioning component 4.

[0051] The base 3 primarily serves a supporting function. To facilitate movement, in this embodiment, a pulley system is provided at the bottom of the base 3, allowing the operator to move the entire device to a desired location. Furthermore, a guide rail 31 is provided on the base 3, which provides sliding engagement for the first and second clamping assemblies 1 and 2. The first and second clamping assemblies 1 and 2 are primarily used for clamping and transporting pipes (in this embodiment, firefighting pipes). The first and second clamping assemblies 1 and 2, respectively, are used to clamp the first and second pipes 1a and 1b. The structures of the first and second clamping assemblies 1 and 2 are identical, and the first clamping assembly 1 will be used as an example.

[0052] Specifically, such as Figure 2 As shown, the first clamping assembly 1 comprises a clamping base 11 and at least two clamping jaws 12. The two clamping jaws 12 are spaced apart on the clamping base 11 to facilitate smooth gripping of the first pipe 1a. The clamping base 11 can be in the form of a sliding plate, with a slider or slide groove structure at its bottom that can slide with the guide rail 31. The clamping jaws 12 are primarily pneumatically actuated and comprise a first cylinder 121, a support plate 122, a first claw hand 123, and a first connecting rod 124. The first cylinder 121 can be fixedly mounted on the clamping base 11. Specifically, the first cylinder 121 is an electric cylinder. The support plate 122 is connected to the first cylinder 121 by welding or riveting, with holes reserved to prevent interference with the output of the first cylinder 121. Two first claw hands 123 can be provided, mirror-symmetrically arranged on the support plate 122. The first claw hands 123 are rotatably mounted on the support plate 122, which can be achieved through a hole-shaft structure, leaving both ends of the first claw hand 123 free. The first connecting rod 124 is rotatably connected to a free end of the first claw hand 123. The first connecting rod 124 is driven by the first cylinder 121 to drive the two first claw hands 123 to rotate and realize a clamping action, so as to clamp the first pipe 1a.

[0053] Optional, such as Figure 2As shown, a cross bracket 125 is provided on the output end of the first cylinder 121. The two ends of the cross bracket 125 are rotatably connected to the two first connecting rods 124, respectively, so that a single first cylinder 121 can control the rotation of the two first claw hands 123. Furthermore, a positioning block 1251 is provided on the cross bracket 125. The positioning block 1251 can adopt a slider structure. The support plate 122 is provided with a positioning groove 1221. The positioning groove 1221 is a smooth linear slide structure. The positioning block 1251 slides in the positioning groove 1221 to guide the cross bracket 125 to move unidirectionally on the support plate 122, so that the first cylinder 121 drives the first claw hands 123 more smoothly.

[0054] And, as Figure 3 As shown, both the first clamping assembly 1 and the second clamping assembly 2 are provided with a first drive device 5, specifically a servo motor. The first drive device 5 can be disposed on a clamping base 11, between two clamping jaws 12. It can be seen that the first pipe 1a and the second pipe 1b are clamped by the clamping jaws 12, and then the first drive device 5 is used to drive the first clamping assembly 1 and the second clamping assembly 2 so that the first pipe 1a and the second pipe 1b move toward each other and abut against each other. Specifically, a rack 52 structure is provided on the side of the guide rail 31. A rotating shaft extends from the output end of the first drive device 5, and a gear 51 is provided on the rotating shaft. The gear 51 can mesh with the rack 52. When the first drive device 5 is activated, the gear 51 can rotate on the rack 52 to drive the first clamping assembly 1 to move.

[0055] like Figure 4 As shown, the positioning assembly 4 can be fixedly mounted on the guide rail 31 to further guide the alignment and smooth docking of the first pipe 1a and the second pipe 1b. There are two sets of positioning assemblies 4, which are arranged in a mirror-symmetrical manner. Specifically, the positioning assembly 4 includes a first sleeve 41, a second sleeve 42, a fixing frame 43, a disassembly rod 44, a second connecting rod 45, and a third cylinder 46. The first sleeve 41 and the second sleeve 42 can be disassembled and assembled with each other. When the first sleeve 41 and the second sleeve 42 are combined, they can form a complete trumpet-shaped cylindrical structure. When the clamping jaws 12 clamp the first pipe 1a and the second pipe 1b and move, if the axis of the first pipe 1a and the second pipe 1b deviates significantly, the first pipe 1a and the second pipe 1b will abut against the inner wall of the first sleeve 41 and / or the second sleeve 42, so that the abutting ends of the first pipe 1a and the second pipe 1b can be corrected and the ends of the first pipe 1a and the second pipe 1b can be smoothly aligned.

[0056] The shape of the fixing frame 43 is not limited. It is mainly used to support other components. The fixing frame 43 can be fixedly set on the guide rail 31, which is beneficial to improving the alignment of the first sleeve 41, the second sleeve 42 and the clamping claw 12. The disassembling rod 44 adopts a cross-rotating rod structure, which is rotatably set on the fixing frame 43. One end of the disassembling rod 44 is connected to the bottom of the first sleeve 41 and the second sleeve 42 respectively, so that when the disassembling rod 44 cross-rotates, it can drive the first sleeve 41 and the second sleeve 42 to move closer or separate. The number of second connecting rods 45 can be two. The second connecting rod 45 is rotatably connected to the other end of the disassembling rod 44, which is beneficial to improving the stability of the disassembling rod 44 when rotating. The third cylinder 46 is specifically an electric cylinder. The third cylinder 46 is fixed on the fixing frame 43 and is located on the lower side of the disassembling rod 44. The output end of the third cylinder 46 is rotatably connected to the second connecting rod 45.

[0057] As can be seen, when the third cylinder 46 outputs power, the second connecting rod 45 drives the disassembly rod 44 to complete a cross-rotation motion, causing the first sleeve 41 and the second sleeve 42 to move closer to and away from each other, thereby completing the disassembly process between the first and second pipes 1a, 1b. After the first and second pipes 1a, 1b are connected or before entering the positioning assembly 4, the first and second sleeves 41, 42 are in a disassembled and open state.

[0058] Further, such as Figure 5 As shown, in order to improve the accuracy of the engagement of the first sleeve 41 and the second sleeve 42, a positioning hole 411 is provided in the first sleeve 41, and a positioning column 421 is provided in the second sleeve 42. The positioning column 421 is adapted to the size of the positioning hole 411, and when the first sleeve 41 and the second sleeve 42 are engaged, the positioning column 421 can be inserted into the positioning hole 411 to guide the first sleeve 41 and the second sleeve 42 to form a complete cylinder to avoid deviation.

[0059] In addition, if Figure 6 、 Figure 7 As shown, a lifting frame 32 is provided on the base 3. The lifting frame 32 can adopt a hydraulic lifting frame 32 or a gear chain drive or belt drive lifting structure. In this embodiment, the lifting frame 32 is a vertical lifting structure, wherein the lifting frame 32 has a movable lifting platform 33, and part of the structure of the lifting platform 33 extends to the upper side of the guide rail 31. The lifting platform 33 is provided with a fixed clamping hand 34, which is located between the first clamping component 1 and the second clamping component 2, and is used to clamp the first pipe 1a and the second pipe 1b that are connected to each other. In actual use, the fixed clamping hand 34 can be located between the two positioning components 4 after being lowered by the lifting frame 32.

[0060] Specifically, the fixed gripper 34 includes a second claw hand 341, a screw 342, and a second drive device 343. The shape of the second claw hand 341 is similar to the arc-shaped clamping structure. Similar to the first claw hand 123, the number of second claw hands 341 can be set to two, and they are arranged in a mirror-symmetrical manner with each other, and the arc-shaped structure is provided with at least two on a single side. Among them, the bottom of the second claw hand 341 adopts a movable block shape and is provided with a threaded structure. The screw 342 is rotatably set on the lifting platform 33. The screw 342 can cooperate with the threaded structure at the bottom of the second claw hand 341. Optionally, the screw 342 can adopt two threaded sections with different rotation directions to facilitate the movement and clamping of two opposing second claw hands 341. The second driving device 343 is specifically a servo motor. The second driving device 343 can be fixedly set on the lifting platform 33. The output end of the second driving device 343 is connected to the screw rod 342. When the second driving device 343 is started, it can drive the screw rod 342 to rotate, so that the second claw hand 341 completes the clamping action.

[0061] In some embodiments, a positioning slide bar (not shown) is provided at the bottom of the second claw hand 341 , which can be engaged with the hole shaft to guide the movement of the second claw hand 341 and improve stability.

[0062] Further, such as Figure 7 As shown, a second cylinder 331 is provided on the lifting platform 33, and the second cylinder 331 is specifically an electric cylinder. A limit block 332 is provided at the output end of the second cylinder 331, and a second claw hand 341 is provided with a limit groove 3411, and the extension direction of the output end of the second cylinder 331 is parallel to the movement direction of the second claw hand 341. After the second claw hand 341 completes clamping the connected pipe, the second cylinder 331 drives the limit block 332 to abut against the limit groove 3411, thereby realizing a secondary locking effect to improve the clamping effectiveness of the second claw hand 341. Furthermore, the limit block 332 has a first abutting bevel 3321, and the limit groove 3411 is provided with a second abutting bevel 3412. When the second cylinder 331 drives the limit block 332 to move, the first abutting bevel 3321 and the second abutting bevel 3412 abut with each other in surface contact and the limit block 332 is inserted into the limit groove 3411, that is, the first abutting bevel 3321 is parallel to the second abutting bevel 3412, and the first abutting bevel 3321 cooperates with the second abutting bevel 3412 to improve the abutment strength of the limit block 332.

[0063] Working principle: Figure 1As shown, the operator places the first pipe 1a and the second pipe 1b to be connected on the clamping claws 12 of the first clamping assembly 1 and the second clamping assembly 2 respectively, starts the first cylinder 121 so that the first claw hand 123 clamps the first pipe 1a and the second pipe 1b, and then starts the first driving device 5 to make the first clamping assembly 1 and the second clamping assembly 2 move toward each other along the guide rail 31, so as to drive the first pipe 1a and the second pipe 1b to move toward each other and gradually approach each other, and completes the engagement of the positioning assembly 4 before the first pipe 1a and the second pipe 1b, and then starts the third cylinder 46. At this time, the third cylinder 46 is started, and the first sleeve 41 and the second sleeve 42 are engaged under the drive of the third cylinder 46. The first pipe 1a and the second pipe 1b are gradually further aligned with the pipe ports before connection through the positioning assembly 4. The operator can connect the ports of the first pipe 1a and the second pipe 1b through the existing connection tools. After the pipe connection is completed, the positioning assembly 4 is reset, and the lifting frame 32 can be driven upward a certain distance so that the fixed clamping hand 34 is closer to the connected pipe. At this time, the second driving device 343 is started to drive the second claw hand 341 to clamp the connected pipe, and then the clamping claw 12 is released and reset. Finally, the lifting frame 32 drives the lifting platform 33 to move upward to move the connected pipe upward to the desired position, and this cycle is repeated.

[0064] In some embodiments, the first pipe 1a and the second pipe 1b can be conveyed to the clamping jaw 12 via a conveyor belt or conveying rollers to improve the degree of automation of the entire equipment.

[0065] The above description is only a preferred embodiment of the present invention. To keep the description concise, not all possible combinations of the various technical features in the above embodiment are described. This does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
