Description

Technical Field

[0001] The utility model relates to the field of sledges for laying natural gas pipelines, in particular to a natural gas pipeline welding composite sledge. Background Art

[0002] The sled itself is a means of transportation often used in areas near the polar regions. It can be generally regarded as a large skateboard. The skateboard is pulled by animals. The skateboard has a large contact area with the snow and low resistance, so it is easy and convenient to transport supplies or drive to distant places. For example, the sled in the dog sled is a representative of the sled.

[0003] Natural gas pipelines are usually buried underground. After wiring, sections of pipelines are welded together to form a pipeline network. Sledges are often used for natural gas pipeline wiring. In actual use, the sledge area is generally not small, with several layers of natural gas pipelines stacked on it. Then it is towed by an excavator and moves along the pre-dug pipe trench on the ground. When it reaches a wiring location, a section of pipeline is placed in the pipe trench and then continues to move forward. This cleverly saves a lot of effort. However, the size of the sledge is generally fixed, and the number of pipelines that can be carried at one time is also limited. Excessive sledges will cause danger. The scale of the natural gas buried pipeline project and the number of pre-buried pipelines determine how many batches the pipelines should be pulled in. The area for natural gas pipeline wiring is very large, and the distance from the wiring node to the starting point is generally very far, which will increase unnecessary labor and power costs. Generally, natural gas pipeline construction companies do not prepare many different sledges. When the project volume is large and the sledge's carrying capacity is relatively small, they will fall into a dilemma. For this purpose, a natural gas pipeline welding composite sledge is provided. Utility Model Content

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the utility model is that the size of the commonly used natural gas pipeline wiring sledge is fixed and the carrying capacity for the pipeline is also limited, so it cannot be well adapted to pipeline construction on a wider scale.

[0006] 2. Technical Solution

[0007] In order to solve the above technical problems, the technical solution provided by the present invention is: a natural gas pipeline welding composite sled, comprising a base, one end of the base is connected to a bracket, and the bracket is connected to a ring.

[0008] An expansion platform is connected to both sides of the base, and the inner groove contour of the expansion platform is consistent with the outer contour of the base. A drive shaft is rotatably connected in the base, and a motor that cooperates with the drive shaft is connected in the base. The drive shaft is arranged at both ends of the motor, and a pulley 1 is connected to the drive shaft. A screw sleeve is rotatably connected on both sides of the base, and one end of the screw sleeve is connected to a pulley 2. A transmission belt is commonly connected between the pulley 1 and the pulley 2, and a screw is connected in the screw sleeve. A limit plate is connected at one end of the screw, and the end of the screw away from the limit plate is connected to the expansion platform.

[0009] Furthermore, a bottom plate is connected to the top of the base, and a plurality of dampers are connected between the base and the bottom plate. The dampers are first used to support the bottom plate, and also serve as buffering devices to provide a buffering effect on the base for the bottom plate supporting the natural gas pipeline, thereby providing protection for components such as the motor in the base.

[0010] Furthermore, the bottom plate and the top surface of the expansion platform are both connected with a frosted layer, which increases the friction resistance and improves the stability of the natural gas pipeline placed on the bottom plate and the expansion platform as much as possible.

[0011] Furthermore, the bottom of the expansion platform is connected with a plurality of plug rods, which provide support effect and enhance the load-bearing function of the expansion platform. The bottom of the base is connected with a plurality of storage grooves that cooperate with the slots. The storage grooves leave a certain space under the base to provide a recovery position for the plug rods. The plug rods and the bottom of the base are both connected with arc surfaces. The arc surface design of the bottom of the plug rod makes the plug rod look like a semi-cylinder as a whole. The arc surface setting of the bottom of the base is mainly reflected in the bottom surface between each storage groove, and the arc-shaped boss protrudes downward. On the one hand, such a design can reduce the resistance of the sled when moving on the ground, and on the other hand, it can avoid the soil on the ground from being scraped up and accumulated under the sled, which has a negative impact on the movement effect.

[0012] 3. Beneficial Effects

[0013] The advantage of the present invention over the prior art is that the device divides the sled into a base part and an expansion part on the basis of the traditional single-structure sled, and expansion platforms are respectively added on both sides of the base part as the main body. The expansion platforms can be retracted and extended through relevant components, so that different widths can be selected to a certain extent, and it can be suitable for pipeline construction with a wider range of engineering scales.

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] Example 1

[0022] Combined with attachment Figure 1-4 In order to solve the above technical problems, the technical solution provided by the utility model is: a natural gas pipeline welded composite sled, comprising a base 1, one end of the base 1 is connected to a bracket 14, the bracket 14 is connected to a ring 15, the bottom plate 3 and the top surface of the expansion platform 2 are both connected to a frosted layer 13, by increasing the friction resistance, the natural gas pipeline placed on the bottom plate 3 and the expansion platform 2 is as stable as possible, the top of the base 1 is connected to the bottom plate 3, a plurality of dampers 4 are connected between the base 1 and the bottom plate 3, the damper 4 is first used to support the bottom plate 3, and also as a buffer device, it has a buffering effect on the base 1 for the bottom plate 3 carrying the natural gas pipeline, and provides protection for the motor 5 and other components in the base 1.

[0023] By combining the hook carried by the excavator with the ring 15 on the base 1, the excavator drives the sled carrying the pipeline to move. The base 1 is composed of a frame structure at the bottom and a bottom plate 3 at the top. The bottom plate 3 serves as the top surface of the base 1 and is used to directly carry the pipeline. Since the sled is composite and multifunctional, many electronic control components and transmission components are set in the frame of the base 1. Therefore, multiple dampers 4 are installed under the bottom plate 3 to buffer the pipeline pressure and protect the components in the frame from serious damage. In this specification and the drawings, the dampers 4 are divided into two groups. One group is arranged at the edge of the bottom plate 3, mainly for support, and the other group is arranged near the motor 5, mainly for protecting the motor 5. When the device is used in practice, it can be reasonably designed according to objective requirements.

[0024] Example 2

[0025] Combined with attachment Figure 1-5 , the base 1 is connected with an expansion platform 2 on both sides, the inner groove contour of the expansion platform 2 is consistent with the outer contour of the base 1, the base 1 is rotatably connected with a drive shaft 6, the base 1 is connected with a motor 5 that cooperates with the drive shaft 6, the drive shaft 6 is located at both ends of the motor 5, and a pulley 7 is connected to the drive shaft 6. The base 1 is rotatably connected with a screw sleeve 10 on both sides, one end of the screw sleeve 10 is connected with a pulley 2 9, and a transmission belt 8 is commonly connected between the pulley 1 7 and the pulley 2 9, a screw 11 is connected in the screw sleeve 10, one end of the screw 11 is connected with a limit plate 12, and the end of the screw 11 away from the limit plate 12 is connected to the expansion platform 2, and the bottom of the expansion platform 2 The connection is provided with multiple insertion rods 16, which provide support effect and enhance the load-bearing function for the expansion platform 2. A plurality of storage grooves 17 that cooperate with the slots are connected at the bottom of the base 1. The storage grooves 17 leave a certain space under the base 1 to provide a recovery position for the insertion rods 16. The insertion rods 16 and the bottom of the base 1 are both connected with an arc surface 18. The arc surface 18 at the bottom of the insertion rod 16 makes the insertion rod 16 look like a semi-cylinder as a whole. The arc surface 18 at the bottom of the base 1 is mainly reflected in the bottom surface between each storage groove 17, and the arc-shaped boss protrudes downward. On the one hand, such a design can reduce the resistance of the sled to move on the ground, and on the other hand, it can avoid the soil on the ground from being scraped up and accumulated under the sled, which has a negative impact on the movement effect.

[0026] The motor 5 is operated to drive the drive shaft 6 to rotate, and under the action of the belt transmission mechanism composed of pulley 1 7, pulley 2 9 and transmission belt 8, the screw sleeve 10 also rotates. The above components are specifically distributed as follows: the motor 5 is placed at the center position of the base 1 as much as possible. It is a motor 5 with two-way output. The drive shaft 6 is connected to the power output ends on both sides of the motor 5. It can also be understood that the two drive shafts 6 are respectively connected to the two ends of the motor 5 in opposite directions, and then the pulley 1 7 is as close as possible to the end of the drive shaft 6, so that a relatively ample movement space can be left for the subsequent screw 11. The screw sleeve 10 is connected in a rotating state on the base 1 on one side of the drive shaft 6. The two screw sleeves 10 in the base 1 are respectively geometrically centered with the motor 5. The center is symmetrically arranged, and there is a screw 11 in the screw sleeve 10. The outer end of the screw 11 is connected to the outermost inner wall of the expansion platform 2. There are two expansion platforms 2, which are respectively sleeved on both sides of the base 1. Due to this positional relationship, when the screw sleeve 10 rotates, the screw 11 will not rotate, but can only move, showing a telescopic effect on one side of the base 1, thereby realizing the retraction and position adjustment of the expansion platform 2 on one side of the base 1. The expansion platform 2 and the bottom plate 3 on the base 1 are connected to form a platform for carrying pipes. Therefore, when the expansion platform 2 extends outward, it cannot extend too far outward, resulting in a gap between the base 1 and the expansion platform 2, affecting the convenient use of the sled when arranging the pipe. This is provided by the limiting plate 12 on the inner end of the screw 11.

[0027] During the specific implementation of the present invention, when the sled is used for transporting and wiring natural gas pipelines, the width of the bearing surface of the sled can be adjusted according to the number of bearing pipelines required to reasonably place more natural gas pipelines. The screw sleeves 10 on both sides of the base 1 are rotated by the motor 5 and the belt drive. The start and stop of the motor 5 and the regulating mechanism are realized by setting relevant buttons and a control box. The specific electrical connection, electric control program and wiring belong to the well-known existing technology, so they are not shown here. The specific design situation, as long as it does not affect the normal operation of the device, Just install it properly. After the screw sleeve 10 rotates, the screw 11 in the screw sleeve 10 moves in and out of the base 1, thereby driving the expansion platforms 2 on both sides of the base 1 to move outward or inward. In this way, the width of the sled carrying platform changes, making it more suitable for changing construction requirements and scenarios. After the adjustment is completed, put the pipeline on it. Finally, like using a general sled equipment, use an excavator or other vehicle tool, hang the hook of the traction rope on the ring 15 of the base 1, drag the sled carrying the natural gas pipeline, move it along the ground pipe groove, lay out the wires reasonably, and weld it.

[0028] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
