Description

Technical Field

[0001] This invention relates to the field of heating pipeline technology, specifically to a pipe sleeper tool and its auxiliary installation equipment for laying heating pipelines on the ground. Background Technology

[0002] Heating pipelines are pipes that transport hot water or steam. They deliver the heat energy produced by boilers in power plants and other factories to buildings through heat media such as steam and hot water to meet the needs of production and daily life. Existing heating pipelines are divided into above-ground and underground laying according to their laying method. Among them, above-ground laying includes high-support, medium-support, ground-support and ground-level laying. Ground-level laying requires the use of pipe supports to elevate the pipeline to maintain a certain distance from the ground for drainage.

[0003] For example, application number 202120343918.1, "A pipe sleeper for municipal drainage pipes", includes a left pipe sleeper and a right pipe sleeper. The left and right pipe sleepers are detachably connected by a set pin, forming a circular space. An inner pipe is placed in the circular space. A positioning component is detachably installed between two adjacent pipe sleepers. The positioning component includes a mounting plate, an outer plate, a fixed shaft, an inner plate, and a roller. The mounting plate is located outside the connection between the two pipe sleepers. The two outer plates are respectively fixed to the front and rear surfaces of the mounting plate. The inner plate is located inside the outer plate. A fixed shaft is set between the inner plate and the outer plate along their length direction. The roller is rotatably sleeved on the fixed shaft.

[0004] For example, application number 202023031956.8, "A Novel Underground Pipeline Pillow Structure," includes an upper pipe pillow and a lower pipe pillow. The upper middle part of the upper pipe pillow and the lower middle part of the lower pipe pillow are both arc-shaped opening structures. A snap-fit ​​connector is provided on the top of the upper pipe pillow, and a snap-fit ​​groove is provided on the bottom of the lower pipe pillow. Half-position snap-fit ​​grooves are provided on the right side of both the upper and lower pipe pillows. The two half-position snap-fit ​​grooves can be combined to form a complete snap-fit ​​groove. Half-position snap-fit ​​heads are provided on the left side of both the upper and lower pipe pillows. The two half-position snap-fit ​​heads can be combined to form a complete snap-fit ​​connector. The side of the half-position snap-fit ​​head is provided with a concave-convex interlocking structure, and the inner side of the half-position snap-fit ​​groove is a pre-destruction opening structure.

[0005] Although the pipe sleeper structure design in the existing patents is reasonable, there is currently no equipment specifically for the installation or assembly of pipe sleepers. When using them, the pipe sleepers still need to be installed on the pipes manually, which increases labor costs, makes the installation process time-consuming and labor-intensive, and results in low installation efficiency. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes a pipe sleeper fixture and its auxiliary installation equipment for laying heating pipelines on the ground.

[0007] The technical problem to be solved by this invention is achieved by the following technical solution:

[0008] A pipe sleeper fixture for laying heating pipelines on the ground includes a first pipe sleeper and a second pipe sleeper with symmetrical structure. The first pipe sleeper and the second pipe sleeper are fitted together to form a pipe sleeper with an inner circle and an outer square structure. The mating surfaces of the first pipe sleeper and the second pipe sleeper are provided with locking screw holes of appropriate size and combined positioning components.

[0009] As a further improvement of the present invention, both the No. 1 tube pillow and the No. 2 tube pillow are in the form of square plate structures.

[0010] As a further improvement of the present invention, a fixing groove with a semi-circular structure is provided on the mating surface of the first tube pillow and the second tube pillow.

[0011] As a further improvement of the present invention, the combined positioning component includes a positioning groove disposed on the mating surface of the first tube pillow and located in front of the locking screw hole and on the mating surface of the second tube pillow and located behind the locking screw hole, and a positioning strip disposed on the mating surface of the first tube pillow and located behind the locking screw hole and on the mating surface of the second tube pillow and located in front of the locking screw hole, wherein the positioning groove and the positioning strip are mutually adapted and engaged.

[0012] A pipe sleeper auxiliary installation device for ground laying of heating pipelines is used to install a pipe sleeper tool for ground laying of heating pipelines. It includes two movable frames symmetrically distributed on the left and right, two connecting frame plates connected to the top of the two movable frames, and four auxiliary installation components horizontally slidably installed on the bottom of the two connecting frame plates in the left and right direction. The four auxiliary installation components are symmetrically distributed on the left and right and have lifting functions.

[0013] As a further improvement of the present invention, each of the four auxiliary installation components includes a connecting rod that is horizontally slidably installed at the bottom of the connecting frame plate in the left-right direction, and a support frame disposed at the bottom of the connecting rod. The support frame is composed of an upper frame rod, a lower frame rod, and a connecting frame rod located on the front and rear side walls of the upper frame rod and the lower frame rod, which are symmetrically distributed vertically. The upper frame rod is connected to the connecting rod.

[0014] As a further improvement of the present invention, the upper part of the lower frame rod is provided with placement grooves distributed in the left and right direction, the relatively inner end of the lower frame rod is provided with a clamping port communicating with the placement groove, and the relatively outer side of the support frame is provided with an installation cylinder and an installation push plate communicating with the placement groove.

[0015] As a further improvement of the present invention, the connecting rod is hollow inside and is provided with an electric telescopic rod, which is connected to the lower frame rod.

[0016] As a further improvement of the present invention, the bottom of the connecting frame plate is provided with a guide slide rail arranged in the left-right direction and a guide slide block provided on the guide slide rail, and the top of the connecting rod is fixedly connected to the guide slide block.

[0017] As a further improvement of the present invention, the guide slide is provided with a locking screw that abuts against the end face of the guide slide rail.

[0018] The beneficial effects of this invention are:

[0019] This invention, through the use of a movable frame, auxiliary installation components mounted on the movable frame, a support frame with clamping ports and capable of loading pipe supports, and an installation push plate, allows for the pre-clamping of the pipe before the pipe is secured by the pipe support instead of the clamping ports, thus completing the pre-assembly of the pipe support. Subsequently, operators only need to tighten the locking screws. Compared with existing technologies, this invention significantly reduces labor costs, saves time and effort during installation, and improves installation efficiency. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figures 1 to 3 As shown, a pipe sleeper fixture for laying heating pipelines on the ground includes a first pipe sleeper component 1 and a second pipe sleeper component 2. The first tube pillow component 1 and the second tube pillow component 2 are symmetrically distributed on the left and right sides and are both square plate-shaped structures. The first tube pillow component 1 and the second tube pillow component 2 can be fitted together to form a tube pillow with an inner circle and an outer square structure. The middle of the right side fitting surface of the first tube pillow component 1 and the middle of the left side fitting surface of the second tube pillow component 2 are respectively provided with a semi-circular fixing groove 4. The upper and lower ends of the right side fitting surface of the first tube pillow component 1 and the upper and lower ends of the left side fitting surface of the second tube pillow component 2 are respectively provided with horizontally distributed locking screw holes 3. The locking screw hole 3 at the upper end of the right side fitting surface of the first tube pillow component 1 corresponds to the locking screw hole 3 at the upper end of the left side fitting surface of the second tube pillow component 2. The locking screw hole 3 at the lower end of the right side fitting surface of the first tube pillow component 1 corresponds to the locking screw hole 3 at the lower end of the left side fitting surface of the second tube pillow component 2. The right side mating surface of the first tube pillow component 1 and the left side mating surface of the second tube pillow component 2 are also provided with combined positioning components. Specifically, the combined positioning components include positioning slots 5 and positioning strips 6. The positioning slots 5 and positioning strips 6 are sized to fit together and can be matched and engaged. The positioning slots 5 are correspondingly located on the right side mating surface of the first tube pillow component 1 and in front of the locking screw hole 3, and on the left side mating surface of the second tube pillow component 2 and behind the locking screw hole 3. The positioning strips 6 are correspondingly located on the right side mating surface of the first tube pillow component 1 and behind the locking screw hole 3, and on the left side mating surface of the second tube pillow component 2 and in front of the locking screw hole 3.

[0030] The positioning slot 5 and the positioning strip 6 are matched and connected for positioning, so that the first tube pillow 1 and the second tube pillow 2 can be pre-positioned and assembled, and ensure that the pre-assembled first tube pillow 1 and the second tube pillow 2 will not easily loosen, making it convenient for the subsequent locking screws to be screwed into the locking screw holes 3.

[0031] A pipe sleeper auxiliary installation device for ground laying of heating pipelines, such as Figures 4 to 6 As shown, a pipe sleeper fixture for installing a heating pipeline on the ground includes a movable frame and auxiliary installation components mounted on the movable frame.

[0032] Specifically, the movable frame consists of two symmetrically distributed movable frame bodies 7 and connecting frame plates 8 connected to the top of the two movable frame bodies 7. The two movable frame bodies 7 move in the front-to-back direction. Two connecting frame plates 8 are provided, welded side by side to the top of the two movable frame bodies 7. Each movable frame body 7 consists of two frame columns with wheels on top, distributed front to back, and a reinforcing connecting rod connecting the two frame columns. Four auxiliary installation components are provided, corresponding to the two connecting frame plates 8, which are slidably installed at the bottom of the two connecting frame plates 8 in the left-to-right direction. The two auxiliary installation components at the bottom of each connecting frame plate 8 are symmetrically distributed left and right.

[0033] Furthermore, each of the four auxiliary installation components includes a connecting rod 9 that is horizontally slidable at the bottom of the connecting frame plate 8 in the left-right direction, and a support frame disposed at the bottom of the connecting rod 9.

[0034] Specifically, the bottom of the two connecting frame plates 8 is provided with four guide rails 18 arranged in the left-right direction. Four guide slide blocks 19 are slidably installed on the four guide rails 18. The top of the connecting rods 9 in the four auxiliary installation components is fixedly connected to the four guide slide blocks 19. The four guide slide blocks 19 are provided with locking screws 20 that abut against the end faces of the guide rails 18. The position of the guide slide blocks 19 is fixed by the locking screws 20. In addition, the connecting rods 9 are hollow inside. An electric telescopic rod 17 connected to the support frame is provided inside the connecting rods 9. The electric telescopic rod 17 enables the support frame to be raised and lowered vertically, thereby realizing the lifting function of the support frame.

[0035] The support frame consists of an upper frame rod 10, a lower frame rod 11, and connecting frame rods 12 located on the front and rear side walls of the upper frame rod 10 and lower frame rod 11, which are symmetrically distributed vertically. The upper frame rod 10 is fixedly connected to the bottom of the connecting rod 9, and the upper part of the lower frame rod 11 is provided with placement grooves 13 distributed in the left-right direction. The distance between the upper frame rod 10 and the lower frame rod 11 is required to be greater than the vertical height of the pipe sleeper fixture, so as to facilitate the pipe sleeper to be placed into the placement grooves 13 from the front or rear side of the support frame. The lower frame rod 11 has a clamping port 14 communicating with the placement groove 13 at its inner end. The clamping port 14 is used to clamp and lift the heating pipe. The support frame has an installation cylinder 15 and an installation push plate 16 communicating with the placement groove 13 at its outer end. The width of the installation push plate 16 is within the width range of the placement groove 13. The installation cylinder 15 is used to push the pipe pillow in the placement groove 13 toward the clamping port 14 through the installation push plate 16, thereby fixing and clamping the heating pipe while assembling the pipe pillow.

[0036] Operating principle and working principle:

[0037] In use, place the two No. 1 pipe supports 1 into the two support frames on the left side of the movable frame 7, ensuring the right sides of the two No. 1 pipe supports 1 are aligned with the right side of the support frame. Then, place the two No. 2 pipe supports 2 into the two support frames on the right side of the movable frame 7, ensuring the left sides of the two No. 2 pipe supports 2 are aligned with the left side of the support frame. Next, temporarily connect the ends of the two heating pipes and move the equipment to the connection point. Then, adjust the horizontal height of the support frame using the electric telescopic rod 17 inside the connecting rod 9, aligning the clamping ports 14 on the support frame with the heating pipes. Then, the installer pushes the connecting rod 9 from the left side of the left side of the movable frame 7 to the right, and from the left side of the right side of the movable frame 7 to the left, clamping the ends of the two heating pipes through the clamping ports 14. The pipes are clamped, and then the electric telescopic rod 17 lifts the openings of the two heating pipes upwards. Next, the installation cylinder 15 pushes the first pipe pillow 1 and the second pipe pillow 2 towards the center through the installation push plate 16, replacing the clamping port 14 to lock the openings of the two heating pipes. At the same time, the first pipe pillow 1 and the second pipe pillow 2 disengage from the placement groove 13. During the locking process, the positioning grooves 5 and positioning strips 6 on the first pipe pillow 1 and the second pipe pillow 2 engage accordingly. At this time, the first pipe pillow 1 and the second pipe pillow 2 are pre-installed into a complete pipe pillow. Under the gravity of the heating pipes, the first pipe pillow 1 and the second pipe pillow 2 contact the ground from the bottom of the placement groove 13. Then, the support frame is reset and the device is removed. The subsequent operator screws the locking screw into the locking screw hole 3 to complete the pre-installed pipe pillow assembly.
