Description

Adjustable pipe support frame

technical field

The utility model relates to the technical field of pipeline support, in particular to an adjustable pipeline support frame.

Background technique

Many overhead pipelines in existing pipeline projects, such as water supply pipelines, heating pipelines, oil pipelines, etc., do not have a support frame. or displacement. Since the installation environment varies greatly during on-site installation, if the pipe support is not adjustable, the pipe may not be used due to slight changes in the ground or pipe position, resulting in failure of the pipe support installed and unable to play a supporting role. So the adjustable pipe support came into being.

The existing adjustable pipeline support frame can refer to the Chinese patent application number 201320866934.4, which discloses an adjustable pipeline support, which is composed of a chassis, a lower screw, a screw sleeve, an upper screw and a tray, and the upper end of the lower screw and the upper The lower ends of the screw rods are connected and mutually prepared by screw sleeves, and the parts in contact with each other are threaded, and can simultaneously raise or lower their respective support heights by screwing out or screwing in from the screw sleeves. In order to facilitate operation and height adjustment, the screw rods There is a transmission hole that can apply external force in the middle of the sleeve. The lower end of the lower screw is welded to the chassis. There is a fixing hole on the chassis for positioning and fixing. The upper end of the upper screw is welded to the tray, and the tray is prepared with the pipe it supports. . The utility model adjusts the support height of the lower screw rod and the upper screw rod by rotating the screw sleeve, so as to realize the adjustable performance of the supporting pipe.

But because the screw sleeve and the upper and lower screw rods are threaded, the direction of its lifting is all determined by the precision of the thread. When there is a problem with thread accuracy, the upper and lower screw rods and the screw sleeves are inclined, resulting in the adjustable pipeline support lifting direction not being vertical. After supporting the pipeline, the inclined pallet cannot support the pipeline well due to the weight of the pipeline.

Utility model content

The purpose of the utility model is to provide an adjustable pipe support frame with guiding function.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions:

An adjustable pipe support frame includes a bracket, a screw connected to the bracket in a sliding manner and a tray fixed on the top of the screw, the bracket includes a base and a guide tube fixed to the base, the screw is sleeved in the guide tube and The guide pipe is slidingly connected, the lead screw is threadedly connected with a drive sleeve, and the other end of the guide pipe fixedly connected to the base abuts against the drive sleeve.

By adopting the above scheme, the driving sleeve is rotated, and the rotary motion of the driving sleeve is converted into the linear motion of the screw itself through the threaded screw, so that the screw moves up and down along the guide tube. When the screw goes up and down through the drive sleeve, the screw stays in the guide tube except for the part that slips out of the guide tube, and the part of the screw that stays in the guide tube slides along the inner wall of the guide tube to prevent the screw from tilting up and down. The tube acts as a guide. And because the tray can only lift and not rotate relative to the guide tube, even if the pipeline has been supported on the supporting plate, the pallet that can only be lifted can still lift the pipeline and adjust the height of the pipeline through screw transmission. And some adjustable pipe support frames that the tray rotates relative to the lead screw, the support frame must be adjusted before the pipeline can be erected.

By adopting the above scheme, when the upper surface of the tray abuts against the outer wall of the pipe, and the tangent plane is tangent to the outer wall of the pipe, the tray exerts two identical radial forces from both sides of the lower part of the pipe, the two radial forces and the gravity of the pipe itself The balance of the three forces makes the pipe securely placed on the pallet. Moreover, the V-shaped tray can support pipes of different specifications, which improves the adaptability of the adjustable pipe support frame.

Preferably, the edges on both sides of the tray extend downward to form reinforcing ribs.

By adopting the above scheme, the reinforcing rib prevents the middle part of the V-shaped tray from being broken due to the overweight of the pipe, thereby strengthening the strength of the tray and prolonging the life of the tray.

Preferably, the base includes a cross-shaped square tube and a column fixed to the end of the square tube.

By adopting the above scheme, since the square pipe is in the shape of a cross, four uprights are fixedly connected to the base, and the adjustable pipe support frame is stood on the ground through the uprights. The stability of the adjustable pipe support pipe depends on the length of the vertical line from the center point to the connecting line of the two uprights, and four uprights are more stable than three uprights. At the same time, it is also easier to install.

Preferably, the upright column has a through hole and is slidably connected with a stud, the stud runs through the through hole and is threadedly connected with two nuts, the nuts are in contact with the upper and lower surfaces of the base respectively, and the end of the stud away from the tray is fixedly connected with a foot .

By adopting the above-mentioned solution, the nuts are used to adjust the relative position of the stud and the column support, so that the adjustable pipe support frame can adapt to different ground environments and ensure the stability of the adjustable pipe support frame.

Preferably, a disk is fixedly connected to the center of the base, and a reinforcement frame is provided between the base and the guide tube, one end of the reinforcement frame is fixedly connected to the base, and the other end is fixedly connected to the guide tube.

By adopting the above scheme, the disk strengthens the strength of the base, and the reinforcing frame strengthens the strength between the guide tube and the reinforcing paper, which ensures the strength of the bracket, disperses the gravity transmitted from the pipeline, and ensures that the bracket will not be damaged by the excessive pressure of the pipeline. Heavy and falling apart.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail. Wherein the same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "bottom" and "top "Face", "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.

An adjustable pipe support frame includes a bracket 1, a lead screw 3 slidingly connected with the support 1, and a tray 4 fixedly connected to the top of the lead screw 3. The bracket 1 is used to carry other components of the adjustable pipeline support frame; the lead screw 3 is slidably connected to the bracket 1 to complete the lifting of the tray 4; the tray 4 is used to carry the pipeline.

The support 1 includes a base 11 and a guide tube 12 welded together with the base 11, the base 11 is set up horizontally, and the guide tube 12 is set up vertically. The lead screw 3 is sleeved in the guide tube 12 and slidably connected with the guide tube 12 , and can slide out from the upper end of the guide tube 12 . The lead screw 3 is threadedly connected with a driving sleeve 2 , and the driving sleeve 2 abuts against the upper end of the guide pipe 12 . Rotate the drive sleeve 2, and convert the rotary motion of the drive sleeve 2 into the linear motion of the lead screw 3 itself through the threaded lead screw 3. When the lead screw 3 rises, the drive sleeve 2 touches the guide tube 12, and the screw thread on the inner wall of the drive sleeve 2 is turned to push the lead screw 3 up a little; Pull down a little bit, and at the same time, under the influence of gravity, the driving sleeve 2 still abuts against the guide tube 12 . Leading screw 3 just does the reciprocating motion of lifting along guide tube 12 like this. When the lead screw 3 is raised and lowered by the drive sleeve 2, the lead screw 3 stays in the guide tube 12 except for the part that slides out of the guide tube 12, and the part of the lead screw 3 left in the guide tube 12 moves along the inner wall of the guide tube 12. slip. And the outer surface of this part of the leading screw 3 is fitted to the inner wall of the guide pipe 12, and the clearance fit between the two, so that the clearance between the two is extremely small and can be neglected. Therefore, there is no gap for the leading screw 3 to tilt, which prevents the leading screw 3 from tilting up and down, and ensures the repeated motion of the leading screw vertically lifting along the guide tube, so that the guide tube 12 plays a guiding role.

And because pallet 4 can only lift and can not rotate relative to guide tube 12, even if pipeline has been supported on the supporting plate like this, by screw drive, pallet 4 that can only lift can still lift pipeline to adjust the height of pipeline. And some adjustable pipeline support frames that the tray 4 rotates relative to the leading screw 3 must adjust the support frame before the pipeline can be erected.

Wherein, there are inherent handles 21 on both sides of the driving sleeve 2, and the handles 21 are held with both hands. Since the handle 21 gradually shrinks away from the driving sleeve 2 to form a tapered surface, the palm and fingers can be closely attached to the handle 21 to facilitate force application. Push and pull with both hands to rotate the driving sleeve 2 to make the leading screw 3 go up and down. The handle 21 not only provides a focus point for rotating the drive sleeve 2, which facilitates the application of force, but also allows both hands to apply force together. After the pipeline is laid, it prevents the heavy pipeline from being adjusted in height without strength. In addition, the driving sleeve 2 can also be rotated by holding the grip ball 22 , and the grip ball 22 is fixedly connected to the handle 21 and the other end of the driving sleeve 2 . Grip ball 22 is far away from the center of drive cover 2, is longer with respect to handle 21 arm of force, is easy to rotate.

Moreover, a washer 5 is sandwiched between the driving sleeve 2 and the guide tube 12 , and the upper and lower surfaces of the washer 5 abut against the drive sleeve 2 and the guide tube 12 respectively. The washer 5 is made of rubber. On the one hand, it protects the surface of the guided tube 12 from being scratched by the driving sleeve 2; fatigue cracking.

Because no matter leading screw 3 ascends or descends, drive sleeve 2 all firmly arrives on the drive tube. Therefore, the abutting end of the guide tube 12 and the washer 5 extends outward to form an abutting platform 13 . The abutting platform 13 is larger in diameter and higher in strength than other parts of the guide tube 12. It is used to withstand the pressure of the drive sleeve 2 transmitted through the gasket 5. On the one hand, it disperses the pressure of the drive sleeve 2 on the guide tube 12, and protects the upper end of the guide. Fatigue cracking due to stress, on the other hand, reduces other strength requirements and diameters of the guide tube 12 .

The tray 4 is V-shaped and two tangent planes are formed on the upper surface. When the upper surface of the tray 4 abuts against the outer wall of the pipe, the tray 4 exerts two identical radial forces from both sides of the lower part of the pipe. The two radial forces and the gravity of the pipe itself are balanced by the three forces, so that the pipe can be safely prevented from falling on the tray 4. superior. Moreover, the V-shaped tray 4 can support pipes of different specifications, which improves the adaptability of the adjustable pipe support frame. Moreover, reinforcing ribs 41 are formed extending downward from both side edges of the tray 4 . The reinforcing rib 41 prevents the middle part of the V-shaped tray 4 from breaking due to the overweight of the pipeline, strengthens the strength of the tray 4, and prolongs the life of the tray 4 .

The base 11 includes a cross-shaped square tube 111 and a column 112 fixedly connected to the end of the square tube 111 . Since the square pipe 111 is in the shape of a cross, the base 11 has four legs, and a column 112 is fixedly connected to the end of each leg, and the adjustable pipe support frame is stood on the ground through the four columns 112 . The stability of the adjustable pipe support pipe depends on the length of the vertical line from the center point to the connecting line of the two columns 112 . At the same length, four legs are more stable than three. At the same time, four legs are easier to install than more legs. Four legs only need to weld a square tube 111 in the middle of a square tube 111 both sides to make it very convenient. The disc 113 affixed to the center of the base 11 affixes the four legs together, which strengthens the strength of the base 11 .

And be provided with reinforcement frame 7 between leg and guide pipe 12, reinforcement frame 7 is inclined to set, and reinforcement frame 7 one end is affixed on the leg, and the other end is affixed on the guide pipe 12. Like this, reinforcing frame 7, leg and guide tube 12 form a triangle. The reinforcing frame 7 strengthens the strength between the guide pipe 12 and the reinforcing paper, ensures the strength of the support 1, disperses the gravity transmitted from the pipeline, and ensures that the support 1 will not fall apart due to the excessive weight of the pipeline.

The upright column 112 has a through hole and is slidably connected with a stud 6 , the stud 6 runs through the through hole and is threaded with two nuts 62 , the nuts 62 abut against the upper and lower surfaces of the base 11 respectively, and the end of the stud 6 is away from the tray 4 A support foot 61 is fixedly connected. When the road surface is uneven, the nut 62 is used to adjust the relative position of the stud 6 and the support 1 of the column 112, and the foot 61 is abutted on the ground to ensure the stability of the adjustable pipe support frame, so that the adjustable pipe support frame can adapt to different ground environments.
