Description

Technical Field

[0001] This application relates to the field of heat pipe installation technology, and in particular to a heat pipe structure for urban roads and its construction method. Background Technology

[0002] With the continuous development of the social economy and the increasing improvement of people's living standards, my country's urban construction and centralized heating industry are also booming. As a pressure pipeline for transporting hot water and steam, heating pipelines play an important role in urban construction.

[0003] Regarding the aforementioned technologies, the inventors discovered that during the construction of heating pipelines, it is necessary to first excavate underground to lay the heating pipelines, and then position and install the pipelines within the pipelines. However, due to the loose geology in the water-rich areas of alluvial plains, unstable positioning occurs when installing the positioned pipelines, making it difficult to position the heating pipelines and thus greatly delaying the construction progress. Summary of the Invention

[0004] To improve the stability of heating pipeline positioning in areas with loose soil, this application provides a heating pipeline structure for urban roads and its construction method.

[0005] Firstly, this application provides a heating pipeline structure for urban roads, employing the following technical solution:

[0006] A heating pipe structure for urban roads includes a support frame and a heating pipe. The support frame is used for installation in an underground tunnel, and the heating pipe passes through the support frame. A fixing rod is also provided on the side wall of the support frame. The fixing rod is fixed to the support frame by being set in the soil. A plurality of reinforcing blocks are provided on the outer side wall of the fixing rod, and the reinforcing blocks are spirally distributed along the axis of the fixing rod.

[0007] By adopting the above technical solution, when installing a heating pipeline, personnel install the support frame in the corresponding pit, then fill the sides of the pit with soil to bury the fixing rods in the soil, thus fixing the support frame. After fixing, the pipeline is inserted and installed on the mounting frame to achieve the positioning and installation of the heating pipeline. After positioning, the remaining soil is filled into the pit to level it. The setting of the support frame and fixing rods can fix the support frame by burying the fixing rods in the soil, thereby reducing the probability of the support frame shifting or shaking during the installation of the heating pipeline, thus effectively reducing the probability of unstable positioning when positioning the heating pipeline.

[0008] Preferably, the fixing rod is slidably connected to the support frame, one end of the fixing rod can extend out of the support frame, and the support frame is provided with a driving assembly, which is used to drive the fixing rod to slide along its own axis.

[0009] By adopting the above technical solution and setting a sliding connection between the fixed rod and the support frame, the driving component can drive the fixed rod to slide and insert it into the soil, thereby fixing the support frame. This changes the original method of fixing the fixed rod by burying it in the soil to fixing it by inserting it into the soil, thus reducing the amount of soil excavated when digging the tunnel. It also eliminates the step of pre-burying the fixed rod in the soil, thereby increasing construction efficiency.

[0010] Preferably, the drive assembly includes a drive frame and a pusher. The outer wall of the drive frame is threadedly connected to the inner wall of the support frame. The drive frame is connected to one end of the fixed rod. The pusher is used to push the drive frame to slide. The fixed rod has an insertion thread on one end extending out of the support frame for inserting itself into the inner wall of the pipe pit.

[0011] By adopting the above technical solution and specifically configuring the drive component, the pusher can push the drive frame to slide, thereby causing the drive frame to slide relative to the support frame and rotate simultaneously, so that the fixing rod can be inserted into the soil. This reduces the resistance of inserting the fixing rod into the soil, thereby reducing the difficulty of inserting the fixing rod into the soil and facilitating the operation of relevant personnel.

[0012] Preferably, the pushing member includes a driving gear and a driving rack. The driving gear is rotatably connected to the support frame, and the driving rack meshes with the driving gear. One end of the driving rack near the fixed rod is connected to the driving frame. The support frame is also provided with a rotating frame, which is used to drive the driving gear to rotate. One end of the rotating frame extends out of the support frame.

[0013] By adopting the above technical solution, when the drive frame needs to be pushed, the relevant personnel rotate the rotating frame, which drives the drive gear to rotate, thereby causing the drive rack meshing with the drive gear to slide, and then the drive rack drives the drive frame to slide. The arrangement of the pusher and the rotating frame allows the relevant personnel to drive the drive gear in the support frame to rotate by rotating the mounting frame, thereby causing the drive rack to drive the drive frame to slide, thus facilitating the operation of the relevant personnel.

[0014] Preferably, each of the reinforcing blocks is slidably connected to the fixing rod, the bottom end of each of the reinforcing blocks is located inside the fixing rod, and a return spring is sleeved on the upper part of the reinforcing block. The two ends of the return spring are respectively connected to the inner wall of the fixing rod and the reinforcing block. A sliding component for sliding each of the reinforcing blocks is also provided inside the fixing rod.

[0015] By adopting the above technical solution, the arrangement of the reinforcing block and the return spring ensures that during the insertion of the fixing rod into the soil, the elastic force of the return spring pushes the reinforcing block into the fixing rod, thereby reducing the resistance when the fixing rod is inserted into the soil and facilitating the insertion of the fixing rod. At the same time, compared to the case where the reinforcing block is fixedly connected to the fixing rod, resulting in gaps in the soil during the insertion of the fixing rod, the arrangement of the reinforcing block being located inside the fixing rod during rotation effectively ensures that only gaps remain in the soil for the fixing rod to be filled, thereby increasing the tightness of the contact between the soil and the side wall of the fixing rod.

[0016] Preferably, the sliding assembly includes a rotating rod and a plurality of pushing cams. The rotating rod is located inside the fixed rod and is rotatably connected to the fixed rod. Each pushing cam corresponds to a reinforcing block. One end of each reinforcing block located inside the fixed rod abuts against the side wall of the corresponding pushing cam. Each pushing cam is sleeved on the fixed rod, and the pushing stroke of each pushing cam is different.

[0017] By adopting the above technical solution, when the fixed rod is inserted into the soil, the rotating rod rotates, thereby causing each pushing cam to rotate. This causes the reinforcing block to slide against the outer wall of the pushing cam, allowing the reinforcing block to slide out of the fixed rod and into the soil, thus reinforcing the connection between the fixed rod and the soil. The sliding component allows the rotating rod to drive each pushing cam to rotate, so that each reinforcing block can be pushed by the corresponding pushing cam, thus sliding out of the fixed rod and into the soil, increasing the firmness of the connection between the fixed rod and the soil. At the same time, the different pushing strokes of the pushing cams result in different sliding amounts for each reinforcing block, further increasing the firmness of the connection between the fixed rod and the soil.

[0018] Preferably, the drive frame is further provided with a rotating assembly, which includes a rotating sleeve and a pushing frame. The rotating sleeve is located inside the fixed rod and connected to the rotating rod. The rotating sleeve is threadedly connected to the fixed rod. A return spring is provided at one end of the rotating sleeve near the rotating rod for resetting the rotating sleeve. The pushing frame is slidably connected to the drive frame. One end of the pushing frame near the fixed rod passes through the drive frame and extends into the fixed rod, and can abut against the rotating sleeve during sliding. The other end of the pushing frame is rotatably connected to the drive rack.

[0019] By adopting the above technical solution, when the drive rack drives the pusher to slide, the pusher slides relative to the drive frame and pushes the rotating sleeve to slide. At this time, the return spring is compressed. Since the rotating sleeve is threadedly connected to the fixed rod, the rotating sleeve rotates simultaneously, causing the rotating rod to rotate, which in turn causes the pusher cam to rotate. Due to the presence of the return spring, the contact point between the pusher cam and the reinforcing block is located on its own base circle radius. At this time, the reinforcing block retracts into the fixed rod. After the rotating rod has completed its displacement, the pusher pushes the drive frame to move, and simultaneously drives... The moving frame rotates, causing the fixed rod to slide and rotate, and then insert into the soil. When the fixed rod is fully inserted into the soil, the drive gear reverses, and the pusher moves to the right. Under the elastic force of the return spring, the rotating sleeve returns to its initial position. At this time, the reinforcing block is pushed by the pusher cam, extends out of the fixed rod, and is inserted into the soil. The design of the rotating component allows relevant personnel to insert the fixed rod and reinforcing block into the soil simply by controlling the drive gear, thus facilitating the operation of relevant personnel and improving construction efficiency.

[0020] Preferably, the support frame is further provided with a locking assembly, which includes a locking block and a stop spring. The locking block is slidably connected to the support frame, and the stop spring is used to reset the locking block. The locking block is inserted into the drive frame for locking by the fixed frame, and a guide surface is provided on the side of the locking block near the drive frame.

[0021] By adopting the above technical solution and setting the locking component, when the drive frame moves to the designated position, the drive frame abuts against the guide surface on the locking block, thereby pushing the locking block to slide away from the drive frame. When the drive frame moves to the designated position, the locking block is inserted into the drive frame to lock the drive frame, reducing the probability of the drive frame being displaced due to accidents.

[0022] Preferably, the support frame is also provided with a number of abutment piles, which are located on both sides of the heat pipe. The abutment piles abut against the side wall of the heat pipe to position the heat pipe.

[0023] By adopting the above technical solution, the setting of the contact piles can make the contact piles abut against the side wall of the heating pipe to position the heating pipe, thereby improving the positioning accuracy of the heating pipe and reducing the probability of deformation of the heating pipe.

[0024] Secondly, this application provides a construction method for a heating pipeline structure for urban roads, which adopts the following technical solution:

[0025] A construction method for a heating pipeline structure in urban roads includes the following steps:

[0026] Pipe pit excavation: Digging a pit in the ground for the heating pipeline to be buried;

[0027] Place the support frame: As needed, place the support frame in the dug pipe pit;

[0028] Fixed support frame: The support frame is fixed to the soil inside the pipe pit sidewall by fixing rods;

[0029] Pipe installation: The pipe is threaded through the support frame and positioned on the support frame by the abutment piles;

[0030] Backfilling the pit: Fill the excavated soil into the pipe pit to complete the construction.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The installation of the support frame and fixing rod can fix the support frame by burying the fixing rod in the soil, thereby reducing the probability of the support frame shifting or shaking during the installation of the heating pipe, and thus effectively reducing the probability of unstable positioning when positioning the heating pipe.

[0033] 2. The specific settings of the drive components enable the pusher to slide the drive frame, thereby causing the drive frame to slide relative to the support frame and rotate simultaneously, so that the fixing rod can be inserted into the soil. This reduces the resistance of inserting the fixing rod into the soil, thereby reducing the difficulty of inserting the fixing rod into the soil and facilitating the operation of relevant personnel.

[0034] 3. The sliding component is designed so that the rotating rod can drive each pushing cam to rotate, thereby allowing each reinforcing block to be pushed by the corresponding pushing cam, thus sliding out of the fixed rod and inserting it into the soil, increasing the firmness of the connection between the fixed rod and the soil. At the same time, the different pushing stroke settings of the pushing cams make the sliding amount of each reinforcing block different, thereby further increasing the firmness of the connection between the fixed rod and the soil.

Detailed Implementation

[0043] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0044] Example 1:

[0045] This application discloses a structure for a heat pipe 2 in an urban road. (Refer to...) Figure 1The structure of the urban road heating pipeline 2 includes a support frame 1 and a heating pipeline 2. The support frame 1 is used for installation in an underground tunnel, and a through-hole 11 is opened on the support frame 1 for the heating pipeline 2 to pass through. The heating pipeline 2 passes through the through-hole 11. A fixing rod 3 is also provided on the support frame 1. One end of the fixing rod 3 is fixedly connected to the side wall of the support frame 1. The fixing rod 3 fixes the support frame 1 by being set in the soil. Several reinforcing blocks 4 are provided on the outer side wall of the fixing rod 3, and the reinforcing blocks 4 are spirally distributed along the axis of the fixing rod 3.

[0046] Reference Figure 1 The support frame 1 is also provided with a number of abutment piles 5. Preferably, the number of abutment piles 5 is set to two. The two abutment piles 5 are located at both ends of the support frame 1 along its own width direction. One end of each abutment pile 5 extends into the support frame 1 and abuts against the outer wall of the heat pipe 2 to position the heat pipe 2. Each abutment pile 5 is fixedly connected to the support frame 1 by welding.

[0047] Reference Figure 1 The number of fixing rods 3 is set to eight, with four fixing rods 3 in each group. Each group of fixing rods 3 is located on both sides of the support frame 1 along its width. Two fixing rods 3 in each group are located at the top of the support frame 1 and at both ends of the support frame 1 along its length, respectively. The remaining two fixing rods 3 in each group are located at the bottom of the support frame 1 and at both ends of the support frame 1 along its length, respectively. One end of each fixing rod 3 is fixedly connected to the side wall of the support frame 1 by welding, and the reinforcing block 4 on each fixing rod 3 is fixedly connected to the corresponding fixing rod 3 by welding.

[0048] The implementation principle of the heating pipeline 2 structure for urban roads in Embodiment 1 of this application is as follows: In use, a pipe pit for burying the heating pipeline 2 is first dug in the ground. Then, the support frame 1 is placed in the pre-dug pipe pit. After placement, some soil is filled into the pipe pit at the position of the fixing rod 3 to bury the fixing rod 3 in the soil, thereby fixing the support frame 1. After fixing, the heating pipeline 2 is then passed through the through-groove 11 to complete the positioning of the heating pipeline 2. After all positioning is completed, the pipe pit is filled to complete the construction.

[0049] Embodiment 1 of this application also discloses a construction method for a heating pipeline 2 structure in an urban road, including the following steps:

[0050] S1. Pipe pit excavation: Excavate a pipe pit in the ground for the placement and installation of the heating pipe 2.

[0051] S2. Place the support frame 1: Based on the actual construction positioning requirements, determine the required number of support frames 1 and the pre-installation location, and place the support frame 1 in the excavated pipe pit.

[0052] S3, Fixed support frame 1: The support frame 1 is fixed to the soil inside the side wall of the pipe pit by the fixing rod 3;

[0053] S4. Installing pipes: Pass the heating pipe 2 through the through groove 11 onto the support frame 1, and position it on the support frame 1 through the abutment pile 5;

[0054] S5. Filling the Pit: Fill the excavated soil into the pipe pit and fill the pipe pit completely to complete the construction.

[0055] Example 2:

[0056] The difference between Embodiment 2 and Embodiment 1 in this application is that: (Refer to...) Figure 2 and Figure 3 Each fixed rod 3 is slidably connected to the support frame 1. The support frame 1 has a sliding groove 12 for the fixed rod 3 to slide in, and the sliding direction of the fixed rod 3 is set to the width direction of the support frame 1. One end of each fixed rod 3 can extend outside the support frame 1. The support frame 1 is also provided with eight drive mechanisms 6, and each drive mechanism 6 corresponds to a fixed rod 3.

[0057] Reference Figure 3 and Figure 4 Each drive mechanism 6 includes a drive assembly 61, a sliding assembly 62, and a rotating assembly 63. The drive assembly 61 includes a drive frame 611 and a pusher 612. The pusher 612 includes a drive gear 6121 and a drive rack 6122. The drive gear 6121 is rotatably connected to the support frame 1 via a pin. An extension gear 6123 is also provided below the drive gear 6121. The extension gear 6123 is rotatably connected to the support frame 1 via a pin, and the extension gear 6123 meshes with the drive gear 6121.

[0058] Reference Figure 2 and Figure 3 The support frame 1 is also equipped with four rotating frames 7. Two extended gears 6123 located on the same side of the support frame 1 at the top or bottom are coaxially arranged and fixedly connected to one end of the corresponding rotating frame 7 by bolts. Each rotating frame 7 is rotatably connected to the support frame 1 through a bearing, and the other end of each rotating frame 7 extends out of the support frame 1 for the user to rotate. Each drive gear 6121 meshes with a corresponding drive rack 6122, and each drive rack 6122 is slidably connected to the support frame 1. The sliding direction of each drive rack 6122 is set to the width direction of the support frame 1.

[0059] Reference Figure 3 and Figure 4The rotating assembly 63 includes a rotating sleeve 631 and a pushing frame 632. The pushing frame 632 includes a pushing plate 6321, a pushing rod 6322, and four pushing rods 6323. One end of the pushing rod 6322 is fixedly connected to the pushing plate 6321 by welding and is coaxially arranged with the pushing plate 6321. The side of each pushing plate 6321 away from the driving rack 6122 is fixedly connected to one end of the pushing rod 6323 by welding. The pushing rods 6323 are arranged at equal angles around the circumference of the pushing plate 6321. The end of each pushing rod 6323 away from the pushing plate 6321 is inserted into the driving frame 611 and is slidably connected to the driving frame 611. Each pushing rod 6323 is fitted with a buffer spring 633, which is located inside the driving frame 611 and abuts against both the pushing rod 6323 and the inner wall of the driving frame 611. Each drive rack 6122 is rotatably connected to the corresponding push plate 6321 via a bearing at one end near the corresponding fixed rod 3.

[0060] Reference Figure 3 , Figure 4 and Figure 5 Each drive frame 611 is cylindrical, and the outer wall of each drive frame 611 is threadedly connected to the inner wall of the sliding groove 12. Preferably, the thread pitch between the drive frame 611 and the inner wall of the sliding groove 12 is set to be relatively large to facilitate the rotation of the drive frame 611 along the thread. The contact surfaces between the drive frame 611 and the inner wall of the sliding groove 12 are all set to be smooth surfaces. Each drive frame 611 is fixedly connected to the corresponding fixed rod 3 near one end of the drive frame 611 by welding. The other end of the fixed rod 3 is set as a pointed end, and the pointed end is provided with an insertion thread 33 for inserting itself into the inner side wall of the pipe pit. The insertion thread 33 is integrally formed and fixedly connected to the fixed rod 3.

[0061] Reference Figure 3 and Figure 4 The end of the push rod 6322 away from the push plate 6321 extends in a direction away from the push plate 6321 and passes through the drive frame 611 to reach the fixed rod 3. Both the drive frame 611 and the fixed rod 3 are slidably connected to the push rod 6322. The rotating sleeve 631 is located inside the fixed rod 3 and at the end of the fixed rod 3 near the drive frame 611. One end of the push rod 6322 abuts against the end of the rotating sleeve 631 near the drive frame 611.

[0062] Reference Figure 3 , Figure 4 and Figure 6The rotating sleeve 631 is slidably connected to the fixed rod 3. The fixed rod 3 has a first sliding groove 31 for the rotating sleeve 631 to slide in, and the sliding direction of the rotating sleeve 631 is along the axis of the fixed rod 3. The outer wall of each rotating sleeve 631 is threadedly connected to the inner wall of the corresponding first sliding groove 31. When the rotating sleeve 631 slides along its own axis, it rotates with the fixed rod 3. A return spring 64 is provided on the side of each rotating sleeve 631 away from the push rod 6322. The return spring 64 is located within the first sliding groove 31, and its two ends abut against one side wall of the rotating sleeve 631 and the inner wall of the fixed rod 3, respectively.

[0063] Reference Figure 3 , Figure 5 and Figure 6 Each reinforcing block 4 is slidably connected to a corresponding fixing rod 3. The fixing rod 3 has several second sliding grooves 32 for the corresponding reinforcing block 4 to slide in, and the reinforcing block 4 is located within the second sliding grooves 32. The sliding direction of the reinforcing block 4 is perpendicular to the axis of the fixing rod 3, and each reinforcing block 4 has the same length. One end of each reinforcing block 4 facing out of the corresponding second sliding groove 32 is set as a pointed tip, and the diameter of the bottom end of each reinforcing block 4 is larger than the diameter of the rest. A return spring 65 is also fitted onto the reinforcing block 4. One end of the return spring 65 near the axis of the fixing rod 3 abuts against the top wall of the bottom end of the reinforcing block 4, and the other end of the return spring 65 abuts against the inner wall of the second sliding groove 32.

[0064] Reference Figure 3 , Figure 5 and Figure 6 Each sliding component 62 includes a rotating rod 621 and several pushing cams 622. Each pushing cam 622 corresponds to a reinforcing block 4. The rotating rod 621 is located inside the fixed rod 3 and is coaxially arranged with the fixed rod 3. The end of the rotating rod 621 near the drive frame 611 is fixedly connected to the rotating sleeve 631. Each pushing cam 622 is fixedly sleeved on the rotating rod 621. The base circle radius of each pushing cam 622 is the same, and the stroke of each pushing cam 622 is different. Preferably, the stroke of the pushing cam 622 gradually increases along the axial direction of the rotating rod 621 and towards the tip of the corresponding fixed rod 3. In the initial state, the rotation center of each pushing cam 622 reaches its farthest end wall and abuts against one end of the corresponding reinforcing block 4. At this time, the return spring 65 is in a compressed state, the return spring 64 is in its initial state, and applies elastic force to the rotating sleeve 631.

[0065] Reference Figure 3 , Figure 4 and Figure 6When the relevant personnel rotate the rotating frame 7, the rotation of the rotating frame 7 drives the extension gear 6123 to rotate, causing the drive gear 6121, which meshes with the extension gear 6123, to rotate. This, in turn, causes the drive rack 6122 to slide, thereby achieving the sliding of the push frame 632. When the push frame 632 slides, the buffer spring 633 is compressed to reduce the probability of collision between the push frame 632 and the drive frame 611. At the same time, when the push frame 632 slides, one end of the push rod 6322 extending into the fixed rod 3 abuts against the rotating sleeve 631, thereby pushing the rotating sleeve 631 to slide.

[0066] Reference Figure 3 , Figure 5 and Figure 6 Simultaneously, since the rotating sleeve 631 is threadedly connected to the inner wall of the first sliding groove 31, the rotating sleeve 631 rotates, thereby driving the rotating rod 621 to rotate, causing the pushing cam 622 to rotate. This causes the pushing cam 622 and the corresponding reinforcing block 4 to rotate to the base circle radius, so that the reinforcing block 4 slides and retracts into the fixed rod 3 under the elastic force of the return spring 65. When the rotating frame 7 continues to rotate in the same direction, the pushing frame 632 pushes the drive frame 611 to slide, and at the same time, the drive frame 611 rotates, causing the fixed rod 3 to be inserted into the soil.

[0067] Reference Figure 3 , Figure 5 and Figure 6 The support frame 1 is also equipped with locking components 66. Preferably, there are multiple locking components 66, with each fixing rod 3 corresponding to two locking components 66, located on the upper and lower sides of the corresponding fixing rod 3, respectively. Each locking component 66 includes a locking block 661, a locking rod 662, and a stop spring 663. The locking block 661 is embedded in the support frame 1 and slidably connected to the support frame 1. The sliding direction of the locking block 661 is perpendicular to the axis of the fixing rod 3. One end of the locking block 661 extends out of the inner wall of the support frame 1 and into the sliding groove 12. Each locking block 661 has an arc-shaped guide surface on the side wall near the drive frame 611.

[0068] Reference Figure 3 , Figure 5 and Figure 6Each locking block 661 has its end away from the fixing rod 3 fixedly connected to one end of the locking rod 662 by welding. The locking rod 662 is slidably connected to the support frame 1. A retaining spring 663 is sleeved on the corresponding locking rod 662. One end of the retaining spring 663 abuts against the end of the locking block 661 near the locking rod 662, and the other end of the retaining spring abuts against the inner wall of the support frame 1. The cross-sectional area of ​​the locking block 661 near the locking rod 662 is larger than the area of ​​the rest to reduce the probability of the locking block 661 slipping out. Each drive frame 611 has two locking grooves 6111 corresponding to the locking blocks 661 on its side wall. The locking blocks 661 are locked by being inserted into the locking grooves 6111.

[0069] Reference Figure 3 , Figure 5 and Figure 6 When the drive frame 611 slides to the end of the sliding groove 12, the drive frame 611 abuts against the arc-shaped guide surface on the locking block 661, thereby pushing the locking block 661 to slide away from the drive frame 611. At this time, the abutment spring 663 is compressed. When the locking groove 6111 on the drive frame 611 corresponds to the locking block 661, the locking block 661 slides under the elastic force of the abutment spring 663 and is inserted into the corresponding locking groove 6111 to lock the drive frame 611.

[0070] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 After locking, the rotating frame 7 is reversed, causing the drive gear 6121 to reverse, which in turn causes the drive rack 6122 to slide away from the drive frame 611. This causes the pusher 632 to move away from the drive frame 611, and the push rod 6322 to slide away from the rotating sleeve 631. At this time, under the elastic force of the return spring 64, the rotating sleeve 631 is displaced towards the drive frame 611 and simultaneously reverses, causing the point where the pusher cam 622 abuts against the corresponding reinforcing block 4 to change from the base circle radius to the position where the rotation center reaches its farthest end wall. This causes the reinforcing block 4 to slide outward from the fixed rod 3 and be inserted into the soil for reinforcement.

[0071] The implementation principle of the heating pipe 2 structure for urban roads in Embodiment 2 of this application is as follows: During use, when relevant personnel rotate the rotating frame 7, the rotating frame 7 drives the driving rack 6122 to slide through the extension gear 6123 and the driving gear 6121, thereby realizing the sliding of the push frame 632. When the push frame 632 slides, the buffer spring 633 is compressed to reduce the probability of collision between the push frame 632 and the driving frame 611.

[0072] Simultaneously, during the sliding of the pusher 632, one end of the push rod 6322 extending into the fixed rod 3 abuts against the rotating sleeve 631, thereby pushing the rotating sleeve 631 to slide. Simultaneously, the rotating sleeve 631 rotates, causing the rotating rod 621 to rotate, which in turn causes the pusher cam 622 to rotate. This causes the pusher cam 622 and the corresponding reinforcing block 4 to rotate to the base circle radius, allowing the reinforcing block 4 to slide and retract into the fixed rod 3 under the elastic force of the return spring 65. When the rotating frame 7 continues to rotate in the same direction, the pusher 632 pushes the drive frame 611 to slide, and simultaneously, the drive frame 611 rotates, causing the fixed rod 3 to be inserted into the soil.

[0073] When the drive frame 611 slides to the end of the sliding groove 12 under the action of the push frame 632, the end of the drive frame 611 away from the push frame 632 abuts against the arc-shaped guide surface on the locking block 661, thereby pushing the locking block 661 to slide away from the drive frame 611. At this time, the abutment spring 663 is compressed. When the locking groove 6111 on the drive frame 611 corresponds to the locking block 661, the locking block 661 slides under the elastic force of the abutment spring 663 and is inserted into the corresponding locking groove 6111 to lock the drive frame 611.

[0074] After locking, the relevant personnel reverse the rotating frame 7, causing the drive gear 6121 to reverse, which causes the drive rack 6122 to slide away from the drive frame 611. This causes the pusher 632 to move away from the drive frame 611, and the push rod 6322 to slide away from the rotating sleeve 631. At this time, under the elastic force of the return spring 64, the rotating sleeve 631 is displaced towards the drive frame 611 and simultaneously reverses, causing the point where the pusher cam 622 abuts against the corresponding reinforcing block 4 to change from the base circle radius to the position where the rotation center reaches its farthest end wall. This causes the reinforcing block 4 to slide outward from the fixing rod 3 and be inserted into the soil for reinforcement, thus completing the fixing of the bearing frame 1.

[0075] Example 3:

[0076] The difference between Embodiment 2 and Embodiment 1 in this application is that: (Refer to...) Figure 7 It also includes several power supply components 8, each corresponding to a reinforcing block 4. Each power supply component 8 includes a protruding ring 81 and a power supply sleeve 82. Each protruding ring 81 is sleeved on the side wall of the corresponding reinforcing block 4 and located on the bottom end of the corresponding reinforcing block 4, and is fixedly connected to the reinforcing block 4 by welding. The top wall of the protruding ring 81 abuts against one end of the return spring 65. A power supply rod 811 is also provided on the outer side wall of the protruding ring 81. The number of power supply rods 811 is set to two, and they are distributed at equal angles along the circumference of the axis of the protruding ring 81. One end of each power supply rod 811 is fixedly connected to the outer side wall of the corresponding protruding ring 81 by welding.

[0077] Reference Figure 7 The fixed rod 3 is also equipped with several rotating sleeves 82, which are cylindrical sleeves. Each rotating sleeve 82 corresponds to a reinforcing block 4. The top of each rotating sleeve 82 is fixedly connected to the inner wall of the fixed rod 3 by welding. The inner diameter of each rotating sleeve 82 is larger than the diameter of the second sliding groove 32. Two spiral grooves 821 are also opened on the inner side wall of the rotating sleeve 82. Each rotating rod 811 is located in the corresponding spiral groove 821 and abuts against the inner wall of the corresponding spiral groove 821. The spiral groove 821 is spiral in shape.

[0078] Reference Figure 7 When the pushing cam 622 pushes the reinforcing block 4 to rotate, the reinforcing block 4 slides away from the corresponding pushing cam 622. At the same time, since the rotating rod 811 abuts against the inner wall of the spiral groove 821, the reinforcing block 4 rotates simultaneously, thereby reducing the resistance of the reinforcing block 4 inserted into the soil.

[0079] Reference Figure 7 The fixing rod 3 is also equipped with several shielding components 9, which are used to shield the soil when the fixing rod 3 is inserted into the soil, reducing the probability of soil entering the second sliding groove 32. The shielding components 9 correspond one-to-one with the reinforcing blocks 4. The shielding components 9 are located on the side of the corresponding reinforcing block 4 away from the pushing cam 622. Each shielding component 9 includes a shielding block 91, a shielding rod 92 and a shielding spring 93. Each shielding block 91 is slidably connected to the fixing rod 3. The sliding direction of the shielding block 91 is set to the axial direction of the fixing rod 3. The side of the shielding block 91 near the reinforcing block 4 is also provided with an arc-shaped guide surface.

[0080] Reference Figure 7 Each blocking block 91 has one side wall fixedly connected to the corresponding blocking rod 92. The blocking rod 92 is slidably connected to the fixing rod 3. Each blocking spring 93 is sleeved on the corresponding blocking rod 92. The two ends of each blocking spring 93 are respectively abutted against the inner wall of the fixing rod 3 and the side wall of the blocking block 91 near the blocking rod 92.

[0081] Reference Figure 7 When the reinforcing block 4 slides away from the corresponding pushing cam 622, the top of the reinforcing block 4 abuts against the arc-shaped guide surface on the blocking block 91, thereby causing the blocking block 91 to slide closer to the blocking rod 92, and thus causing the blocking block 91 to open and release the obstruction of the second sliding groove 32. After the blocking block 91 has slid completely, the reinforcing block 4 continues to slide and extends out of the second sliding groove 32.

[0082] The implementation principle of the heating pipe 2 structure for urban roads in Embodiment 3 of this application is as follows: When the pushing cam 622 pushes the reinforcing block 4 to rotate, the reinforcing block 4 slides away from the corresponding pushing cam 622. At the same time, since the rotating rod 811 abuts against the inner wall of the spiral groove 821, the reinforcing block 4 also rotates. During the sliding process of the reinforcing block 4, the top of the reinforcing block 4 abuts against the arc-shaped guide surface on the blocking block 91, thereby causing the blocking block 91 to slide towards the blocking rod 92, thereby opening the blocking block 91 and releasing the obstruction of the second sliding groove 32. After the blocking block 91 has slid completely, the reinforcing block 4 continues to slide and extends out of the second sliding groove 32, inserting into the soil for reinforcement.

[0083] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
