Description

Technical Field

[0001] This utility model relates to the field of natural gas protection, and in particular to a natural gas supply protection frame. Background Technology

[0002] With the acceleration of urbanization and the continuous development of industry, natural gas, as a clean and efficient energy source, has been widely used in urban gas supply systems and industrial applications. As an important facility for transporting natural gas, the safety of natural gas pipelines is of paramount importance. However, natural gas pipelines may be affected by a variety of factors during operation, such as topographic changes, ground subsidence, external impacts, and temperature changes. These factors may cause pipeline deformation, leakage, or even rupture, thereby leading to safety accidents.

[0003] Traditional protective frames typically employ fixed support structures, making them difficult to adapt to complex terrains. They are also prone to gas leakage inside pipelines when subjected to external impacts, affecting their safe operation. Therefore, those skilled in the art have provided a natural gas supply protective frame to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a natural gas supply protective frame. This frame utilizes a rotating cylinder to drive a worm gear, which in turn drives a worm wheel. The worm wheel, in turn, drives a transmission rod on one side. This transmission rod, via a transmission wheel and belt, drives another transmission rod on the other side. These two transmission rods then drive two threaded posts at their lower ends, causing the support block to move downwards. By controlling two lifting mechanisms, the front or rear end of the device can be independently raised or lowered. This bidirectional adjustment capability allows the device to adapt to different terrains and tilt when needed. The worm gear transmission has a self-locking characteristic, automatically locking itself when lifting stops to prevent the device from descending due to gravity. Two threaded pins secure two limiting blocks to the lower end of the groove, preventing the support block from falling and increasing the device's stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a natural gas supply protective frame, including a base, a top seat on the upper surface of the base, a lifting structure at the lower center of the base near the front and rear, and a buffer structure inside both the base and the top seat;

[0006] The lifting structure includes a groove, a cylinder, a worm, a worm wheel, two transmission rods, a transmission belt, a support block, two threaded columns, two limiting grooves, two limiting blocks, two threaded pins, and two transmission wheels. The groove is located at the lower center of the base. The cylinder passes through one side of the base and extends into the groove. The worm is located at the center of the other side of the cylinder. The worm wheel is located at the center of the front end face of the worm. The two transmission rods are rotatably connected to the upper end face of the groove on both sides. The transmission rod located at the upper end of the worm wheel passes through the upper end face of the worm wheel and extends to the lower end face of the worm wheel. The two transmission wheels are fixedly sleeved on the lower outer side walls of the two transmission rods. The transmission belt is fixedly sleeved on the outside of the two transmission wheels.

[0007] The support block is located at the center of the inner wall of the groove. The two threaded columns are fixedly connected to the center of the lower end face of the two transmission rods, and the two threaded columns pass through the center of the upper end face of the support block to the inside of the support block. The two limiting grooves are located at the lower center of the two sides of the support block. The two limiting blocks are located inside the two limiting grooves. The two threaded pins are respectively set at the lower end of the two limiting blocks, and the two threaded pins pass through the two limiting blocks to the upper end of the two limiting blocks. The ends of the two threaded pins are respectively threaded to the lower end face of the base.

[0008] The above technical solution involves rotating a cylinder to drive a worm gear, which in turn drives a worm wheel. The worm wheel then drives a transmission rod on one side, which in turn drives another transmission rod on the other side via a transmission wheel and belt. These two transmission rods then drive two threaded pins at the bottom, causing the support block to move downwards. By controlling the two lifting mechanisms, the front or rear end of the device can be independently raised or lowered. This bidirectional adjustment capability allows the device to adapt to different terrains and tilt when needed. The worm gear transmission has a self-locking characteristic, automatically locking itself when lifting stops to prevent the device from descending due to gravity. Two threaded pins secure two limit blocks to the lower end of the groove, preventing the support block from falling and increasing the stability of the device.

[0009] Furthermore, the buffer structure includes two honeycomb blocks, a first rubber semi-circle, and a second rubber semi-circle. The two honeycomb blocks are located at the lower center of the base and the upper center of the top seat, respectively. The first rubber semi-circle is fixedly connected to the lower end face of the upper honeycomb block, and the second rubber semi-circle is fixedly connected to the upper end face of the lower honeycomb block.

[0010] The above technical solution uses two honeycomb blocks to prevent damage to the internal pipes when the device is impacted from the outside. Two rubber semi-circular sleeves are placed on the outside of the pipes to further buffer the external impact and seal the pipes to prevent gas leakage.

[0011] Furthermore, a protective box is provided on one side of the base, and protective blocks are provided on both sides of the top seat and the other side of the base;

[0012] The above technical solution uses protective blocks to buffer external impacts, preventing surface deformation of the device from affecting internal pipes. It also works in conjunction with two honeycomb blocks to further improve the buffering effect. The protective box protects the two cylinders, preventing external impacts from causing them to rotate and affecting the operation of the device, thus improving the safety of the device.

[0013] Furthermore, the connection between the front and rear ends of the base and the top seat is provided with buckles on both sides near the center;

[0014] By using the above technical solution to fix the base and top seat with buckles, accidental loosening or detachment can be prevented, ensuring a firm and reliable connection and improving the safety of the overall structure.

[0015] Furthermore, the worm and the worm wheel mesh with each other;

[0016] The above technical solution improves the overall operational stability of the device by enabling the worm to drive the worm wheel to rotate through the meshing between the worm and the worm wheel.

[0017] Furthermore, a hinge is provided between one side and the top surface of the protective box;

[0018] The above technical solution allows the protective box to be opened and the two internal cylinders to rotate normally, improving the ease of operation.

[0019] This utility model has the following beneficial effects:

[0020] In this invention, the natural gas supply protective frame rotates by rotating a cylinder to drive a worm gear, which in turn drives a worm wheel. The worm wheel then drives a transmission rod on one side to rotate, which in turn drives another transmission rod on the other side via a transmission wheel and belt. The two transmission rods drive two threaded pins at the lower end to rotate, thereby moving the support block downwards. By controlling the two lifting structures, the front or rear end of the device can be independently raised or lowered. The bidirectional adjustment capability allows the device to adapt to different terrains and tilt when needed. The worm gear transmission has a self-locking characteristic, automatically locking itself when lifting stops to prevent the device from descending due to gravity. Two threaded pins fix two limiting blocks to the lower end of the groove to prevent the support block from falling and increase the stability of the device.

[0021] In this invention, two honeycomb blocks are used to prevent damage to the internal pipes when the device is impacted from the outside. Two rubber semi-circular sleeves are placed on the outside of the pipes to further buffer the external impacts and seal the pipes to prevent gas leakage.

[0022] In this invention, the protective block buffers external impacts, preventing surface deformation of the device from affecting internal pipes. It also works in conjunction with two honeycomb blocks to further enhance the buffering effect. The protective box protects the two cylinders, preventing external impacts from causing them to rotate and affecting the operation of the device, thus improving the safety of the device.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4 One embodiment of this utility model is a natural gas supply protective frame, including a base 1, a top seat 2 on the upper surface of the base 1, a lifting structure 7 at the lower center of the base 1 near the front and rear, and a buffer structure 8 inside both the base 1 and the top seat 2.

[0031] like Figure 2 , 3As shown in Figure 4, the lifting structure 7 includes a groove 701, a cylinder 702, a worm gear 703, a worm wheel 704, two transmission rods 705, a transmission belt 706, a support block 707, two threaded columns 708, two limiting grooves 709, two limiting blocks 710, two threaded pins 711, and two transmission wheels 712. The groove 701 is located at the lower center of the interior of the base 1. The cylinder 702 passes through one side of the base 1 and extends into the groove 701. The worm gear 703 is located at the center of the other side of the cylinder 702. The worm wheel 704 is located at the center of the front end face of the worm gear 703. The two transmission rods 705 are rotatably connected to each other. At the center of the upper end face of the groove 701, near both sides, the transmission rod 705 located at the upper end of the worm wheel 704 passes through the upper end face of the worm wheel 704 and extends to the lower end face of the worm wheel 704. Two transmission wheels 712 are respectively fixedly sleeved on the lower outer side wall of the two transmission rods 705. The transmission belt 706 is fixedly sleeved on the outside of the two transmission wheels 712. By rotating the cylinder 702, the worm 703 is driven to rotate. The worm 703 drives the worm wheel 704 to rotate. The worm wheel 704 drives the transmission rod 705 on one side to rotate. The transmission rod 705 drives the transmission rod 705 on the other side to rotate through the transmission wheel 712 and the transmission belt 706.

[0032] The support block 707 is located at the center of the lower inner wall of the groove 701. Two threaded posts 708 are fixedly connected to the center of the lower end face of the two transmission rods 705, and the two threaded posts 708 pass through the center of the upper end face of the support block 707 on both sides to the interior of the support block 707. Two limiting grooves 709 are located at the lower center of the two sides of the support block 707. Two limiting blocks 710 are located inside the two limiting grooves 709. Two threaded pins 711 are respectively set at the lower end of the two limiting blocks 710, and the two threaded pins 711 pass through the two limiting blocks 710 to the upper end of the two limiting blocks 710, with the ends of the two threaded pins 711... The two transmission rods 705 are threadedly connected to the lower end face of the base 1, and drive the two threaded columns 708 at the lower end to rotate, thereby moving the support block 707 downward. By controlling the two lifting structures 7, the front or rear end of the device can be independently raised or lowered. The bidirectional adjustment capability allows the device to adapt to different terrains and tilt when needed. The worm gear 703 transmission has a self-locking characteristic and can automatically lock when the lifting stops to prevent the device from falling due to gravity. The two limit blocks 710 are fixed to the lower end of the groove 701 by two threaded nails 711 to prevent the support block 707 from falling and increase the stability of the device.

[0033] like Figure 2 and 3As shown, the buffer structure 8 includes two honeycomb blocks 801, a first rubber semi-circle 802, and a second rubber semi-circle 803. The two honeycomb blocks 801 are located at the lower center of the base 1 and the upper center of the top seat 2, respectively. The first rubber semi-circle 802 is fixedly connected to the lower end face of the upper honeycomb block 801, and the second rubber semi-circle 803 is fixedly connected to the upper end face of the lower honeycomb block 801. The two honeycomb blocks 801 prevent damage to the internal pipes when the device is impacted from the outside. The two rubber semi-circles are sleeved on the outside of the pipes to further buffer the external impacts and seal the pipes to prevent gas leakage inside the pipes.

[0034] like Figure 1 As shown, a protective box 3 is provided on one side of the base 1, and protective blocks 6 are provided on both sides of the top seat 2 and the other side of the base 1. The protective blocks 6 buffer the impacts received from the outside, preventing the surface of the device from deforming and affecting the internal pipes. At the same time, they work together with two honeycomb blocks 801 to further improve the buffering effect. The protective box 3 protects the two cylinders 702, preventing external impacts from causing the two cylinders 702 to rotate and affecting the operation of the device, thus improving the safety of the device.

[0035] The base 1 and the top seat 2 are connected at the center of both ends with buckles 4 on both sides. The buckles 4 are used to fix the base 1 and the top seat 2, which can prevent accidental loosening or falling off, ensure a firm and reliable connection, and improve the safety of the overall structure.

[0036] like Figure 3 As shown, the worm 703 and the worm wheel 704 mesh with each other. Through the meshing of the worm 703 and the worm wheel 704, the worm 703 can drive the worm wheel 704 to rotate, thereby improving the operational stability of the entire device.

[0037] like Figure 1 As shown, a hinge 5 is provided between one side and the top surface of the protective box 3. The hinge 5 allows the protective box 3 to be opened and the two internal cylinders 702 to be rotated normally, which improves the convenience of operation.

[0038] Working Principle: When using the device, first connect the base 1 and the top seat 2 via the latch 4. Then, rotate the cylinder 702 to drive the worm gear 703 to rotate. The worm gear 703 drives the worm wheel 704 to rotate, which in turn drives one side of the transmission rod 705 to rotate. The transmission rod 705, through the transmission wheel 712 and the transmission belt 706, drives the other side of the transmission rod 705 to rotate. The two transmission rods 705 drive the two threaded columns 708 at the lower end to rotate, thereby moving the support block 707 downwards. By controlling the two lifting structures 7, the front or rear end of the device can be independently raised or lowered. This bidirectional adjustment capability allows the device to adapt to different terrains and tilt when needed. The worm gear 703 transmission has a self-locking characteristic, automatically locking when lifting stops to prevent... The device descends due to gravity. Two threaded pins 711 fix two limiting blocks 710 to the lower end of the groove 701 to prevent the support block 707 from falling off and increase the stability of the device. Then, two honeycomb blocks 801 prevent damage to the internal pipes when the device is impacted from the outside. Two rubber semi-circular sleeves are placed on the outside of the pipes to further buffer the external impact and seal the pipes to prevent gas leakage. Finally, the protective block 6 buffers the impact from the outside and prevents the device surface from deforming and affecting the internal pipes. It works in conjunction with the two honeycomb blocks 801 to further improve the buffering effect. The protective box 3 protects the two cylinders 702 to prevent external impact from causing the two cylinders 702 to rotate and affect the operation of the device, thus improving the safety of the device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
