Description
Technical Field
[0001] The utility model belongs to the technical field of thermal pipeline construction, in particular to a pipeline protection device used for horizontal directional drilling construction of thermal pipelines. Background Art
[0002] The heat pipe network is also called the heat pipe. It is a heat pipe that runs from the boiler room, direct-fired room, heating center, etc., from the heat source to the heat entrance of the building. When laying the heat pipe, a horizontal directional drill is used. The horizontal directional drill is a construction machine that lays a variety of underground public facilities (pipelines, cables, etc.) without excavating the surface of the ground. It is widely used in the laying of flexible pipelines for water supply, electricity, telecommunications, natural gas, coal gas, oil, etc.
[0003] During the construction process of horizontal directional drilling technology, a directional hole expansion and dragging method is adopted. The hole is first expanded by horizontal directional drilling, and then the thermal pipe is passed through the expanded hole by dragging. When the thermal pipe passes through the expanded hole, there is a huge friction force at the contact point between the thermal pipe and the inner wall of the expanded hole. When the thermal pipe is directly dragged, it is easy to cause the anti-corrosion layer of the outer wall of the thermal pipe to be damaged, thereby affecting the service life of the thermal pipe; in addition, since the part of the thermal pipe that does not enter the expanded hole has a large range of movement, when one end of the thermal pipe is dragged through the expanded hole, the part of the thermal pipe outside the expanded hole lacks limit and is easy to swing, thereby causing the defect that the thermal pipe is easily damaged.
[0004] Based on this, there is an urgent need to design a pipeline protection device for horizontal directional drilling construction of thermal pipelines, so as to prevent the anti-corrosion coating on the outer wall of the thermal pipeline from being damaged during the horizontal directional drilling construction process, and at the same time, limit the range of movement of the thermal pipeline. Utility Model Content
[0005] The technical scheme of the utility model is: a pipeline protection device for horizontal directional drilling construction of a thermal pipeline, comprising a base, a mounting frame, a roller one, a sliding frame, a roller two and an adjustment component, the mounting frame is movably installed in the base, no less than two rollers one are horizontally arranged in parallel on the mounting frame, the sliding frames are symmetrically slidably installed on the mounting frame, no less than two rollers two are longitudinally arranged in parallel on the two sliding frames facing each other, and an adjustment component for adjusting the distance between the two sliding frames to adapt to thermal pipelines with different diameters is arranged between the base and the mounting frame.
[0006] Furthermore, the adjustment assembly includes a connecting block, a bidirectional threaded rod, a worm wheel and a worm. The lower parts of the two sliding frames are threadedly connected to the bidirectional threaded rod through the connecting block. One end of the bidirectional threaded rod is connected to the worm wheel. The edge of the side wall of the base is provided with a worm that meshes with the worm wheel.
[0007] Furthermore, it also includes a hydraulic cylinder. Hydraulic cylinders for driving the mounting frame to adjust the height are installed on both symmetrical sides of the base, and the movable end of the hydraulic cylinder piston rod is connected to the mounting frame.
[0008] Furthermore, it also includes a pulley and a T-shaped connecting frame. The other two sides of the base are symmetrically rotatably connected with the T-shaped connecting frame. A pulley is installed at one end of the T-shaped connecting frame away from the base. When the T-shaped connecting frame is perpendicular to the bottom of the base, the base moves through the pulley.
[0009] Furthermore, it also includes a clamping sleeve and a T-shaped clamping rod. The T-shaped clamping rod is installed on the side wall of the T-shaped connecting frame that rotates toward the side wall of the base. The T-shaped clamping rod is clamped and matched with the clamping sleeve arranged on the side wall of the base.
[0010] Furthermore, a limiting frame for limiting the position of the T-shaped connecting frame is slidably connected to the inner cavity at the lower part of the base.
[0011] Furthermore, ground spikes are evenly spaced at the bottom of the base.
[0012] The beneficial effects are as follows: the rolling friction between the thermal pipe and the horizontal roller 1 on the base and the longitudinal roller 2 on the sliding frame greatly reduces the friction coefficient between the thermal pipe and the expanded hole, thereby preventing the anti-corrosion layer on the outer wall of the thermal pipe from being damaged when the outer wall of the thermal pipe is dragged into the expanded hole, providing protection for the anti-corrosion layer on the outer wall of the thermal pipe, and extending the service life of the thermal pipe; the worm drives the bidirectional threaded rod to rotate through the worm gear, so that the sliding frame can approach or move away in the opposite direction according to the diameter of the thermal pipe, thereby realizing the function of limiting thermal pipes of different diameters.

DETAILED DESCRIPTION
[0018] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.
[0019] Embodiment: A pipeline protection device for horizontal directional drilling construction of a thermal pipeline, such as Figure 1 and Figure 2 As shown, it includes a base 1, a mounting frame 2, a roller 1 21, a sliding frame 3, a roller 2 31 and an adjusting component. The mounting frame 2 is movably installed in the base 1. No less than two rollers 1 21 are horizontally arranged in parallel on the mounting frame 2. When the thermal pipe is pulled, the thermal pipe rolls and rubs against the surface of the roller 1 21 to reduce friction resistance. A rectangular slide groove is symmetrically provided on the top of the mounting frame 2. The sliding frame 3 is slidably installed in the rectangular slide groove. No less than two rollers 2 31 are longitudinally arranged in parallel on the two sliding frames 3 facing each other. An adjusting component for adjusting the distance between the two sliding frames 3 to adapt to thermal pipes of different diameters is arranged between the base 1 and the mounting frame 2. The distance between the two sliding frames 3 is adjusted by the adjusting component to limit the thermal pipe. The setting of the roller 2 31 ensures that the thermal pipe can be pulled to prevent the thermal pipe from being unable to move after being limited by the sliding frame 31.
[0020] like Figure 1 and Figure 2 As shown, the adjustment component includes a connecting block 32, a bidirectional threaded rod 4, a worm wheel 5 and a worm 51. The lower parts of the two sliding frames 3 are commonly threadedly connected with the bidirectional threaded rod 4 through the connecting block 32. One end of the bidirectional threaded rod 4 is connected to the worm wheel 5. A worm 51 meshing with the worm wheel 5 is installed on the left side wall of the base 1. The worm wheel 5 is driven to rotate by the worm wheel 51, thereby driving the bidirectional threaded rod 4 to rotate, thereby driving the two sliding frames 3 to move toward or in the opposite direction through the connecting block 32, thereby adjusting the distance between the sliding frames 3 and realizing the function of limiting the thermal pipes with different diameters.
[0021] like Figure 1 As shown, it also includes a hydraulic cylinder 6. Hydraulic cylinders 6 for driving the mounting frame 2 to adjust its height are installed on both symmetrical sides of the base 1. The movable end of the piston rod of the hydraulic cylinder 6 is connected to the mounting frame 2. The hydraulic cylinder 6 drives its piston rod to extend upward or retract downward to achieve adjustment of the height of the mounting frame 2.
[0022] like Figure 3 and Figure 4As shown, it also includes a pulley 7, a T-shaped connecting frame 70, a clamping sleeve 71, a T-shaped clamping rod 72 and a ground spike 9. The front and rear sides of the base 1 are both symmetrically provided with rectangular grooves, and the T-shaped connecting frame 70 is rotatably connected in the rectangular groove. The end of the T-shaped connecting frame 70 away from the base 1 is installed with a pulley 7. When the T-shaped connecting frame 70 is perpendicular to the bottom of the base 1, the cooperation of the pulley 7 and the T-shaped connecting frame 70 provides a supporting force for the base 1, and the base 1 is displaced by the pulley 7. When the T-shaped connecting frame 70 rotates upward into the rectangular grooves provided on the front and rear sides of the base 1, When the base 1 is in the state of being rotated, the base 1 is supported by the ground spikes 9 installed at the bottom thereof, and the ground spikes 9 can be inserted into a non-hardened horizontal surface, thereby improving the stability of the device when used on the non-hardened horizontal surface; a T-shaped clamping rod 72 is installed on the side wall of the T-shaped connecting frame 70 that rotates toward the side wall of the base 1, and the T-shaped clamping rod 72 is engaged with a clamping sleeve 71 arranged on the side wall of the base 1. After the T-shaped connecting frame 70 rotates into the rectangular groove opened on the front and rear sides of the base 1, the T-shaped clamping rod 72 approaches the clamping sleeve 71 and is engaged with the clamping sleeve 71, thereby fixing the T-shaped connecting frame 70.
[0023] like Figure 3 and Figure 4 As shown, a limiting frame 8 for limiting the position of the T-shaped connecting frame 70 is slidably connected to the inner cavity at the lower portion of the base 1, and a notch matching the rectangular groove provided on the base is provided on the limiting frame 8. When the limiting frame 8 is pulled horizontally and the notch on the limiting frame 8 is directly opposite to the rectangular groove provided on the base, the T-shaped connecting frame 70 can rotate normally. When the notch on the limiting frame 8 is away from the position of the rectangular groove provided on the base, the limiting frame 8 limits the T-shaped connecting frame 70, so that the T-shaped connecting frame 70 cannot rotate.
[0024] When in use, the worm gear 5 is driven by the worm screw 51 to rotate forward and backward, and the worm gear 5 drives the bidirectional threaded rod 4 to rotate forward and backward, thereby making the sliding frames 3 on the left and right sides approach each other or move away from each other in opposite directions, so as to adjust the distance between the sliding frames 3 on the left and right sides according to the thermal pipes with different diameters, thereby limiting the thermal pipes with different diameters. When the thermal pipe is pulled, the friction coefficient between the thermal pipe and the mounting frame 2 and the sliding frame 3 can be reduced due to the horizontal arrangement of the roller 1 21 and the longitudinal arrangement of the roller 2 31, thereby providing protection for the anti-corrosion and anti-rust spray coating on the outside of the thermal pipe; when the pulley 7 needs to be used, first pull the limiting frame 8 to the right side so that the notches on the front and rear sides of the limiting frame 8 are opposite to the rectangular grooves on the front and rear side walls of the mounting frame 2, and the T-shaped connecting frame 70 can move downward along the rectangular grooves on the mounting frame 2, and the T-shaped connecting frame 70 is rotated downward with its connection with the base 1 as the center to a state perpendicular to the bottom of the base 1 (such as Figure 4The stop frame 8 is then moved to the left and reset, so that the T-shaped connecting frame 70 is limited, thereby keeping the T-shaped connecting frame 70 perpendicular to the bottom of the base 1. At this time, the device can be easily moved to the specified position by the rolling of the pulley 7; conversely, when the pulley 7 is not needed, the stop frame 8 is pulled to the left so that the notches on the front and rear sides of the stop frame 8 are opposite to the rectangular grooves on the front and rear side walls of the mounting frame 2. At this time, the T-shaped connecting frame 70 is rotated upward with its connection with the base 1 as the center, and the T-shaped clamping rod 72 approaches the clamping sleeve 71 until the T-shaped clamping rod 72 is clamped into the clamping sleeve 71, and then the stop frame 8 is moved to the right and reset, thereby fixing the pulley 7 on the side wall of the base 1. At this time, the device is placed on the construction plane through the ground spikes 9.

The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of the present application, there will be changes in the specific implementation methods and application scope.
