Description

Technical Field

[0001] The invention relates to mechanical equipment, in particular to a device for supporting a pipeline. Background Art

[0002] During the construction process, our company needs to build a complete drainage system. When building the drainage system, it is usually necessary to consider factors such as the settlement and deformation of the foundation pit. Therefore, it is very important to establish a flexible and anti-deformation drainage system, which is of great significance to ensure the construction progress and quality of the project. When building flexible pipes, our company encountered some technical difficulties. For example, when the pipe is processed by groove machines, cutting machines, pipe cutters and other machines, workers usually use several steel pipes or steel bars to weld a simple bracket and place it on the other end of the processing machine to support the rotation of the pipe. Due to the limitations of the performance of traditional processing machinery, the flatness of the pipe mouth, the depth uniformity of the threaded mouth and the accuracy requirements cannot be guaranteed during the processing. The traditional simple rotating support device is greatly affected by human factors during the pipe processing process. When the pipe is placed on the support device, the center of the pipe will deviate due to the unsatisfactory support accuracy on both sides. The horizontal condition of the pipe and the precise center position are important indicators affecting the processing of the pipe, which often leads to the failure of the pipe processing and the need for secondary rework, which greatly increases the labor cost, reduces work efficiency, and wastes materials.

[0025] The automatic centering method of the pipeline comprises the following steps:

[0026] (a) initial state;

[0027] A return spring is sleeved on the outside of the support column, one end of the return spring abuts against a fixed connecting rod fixed to the bottom of the support column, and the other end abuts against a linkage connecting rod movably arranged on the support column. Under the elastic force of the return spring, the linkage connecting rod abuts against a limit ring fixed to the support column and located at the upper end of the linkage connecting rod;

[0028] A horizontally placed support platform is fixed on the top of the support column, and the support platform is connected to a clamping member, the clamping member includes two clamping plates, the clamping plate is provided with two ends respectively hinged on the width direction of the support platform, the central axis of the hinge axis formed at the hinge of the clamping plate and the support platform is perpendicular to the central axis of the support column, the opening direction formed between the two clamping plates is upward, and the distance between the two clamping plates gradually decreases from top to bottom along the vertical direction, the extension direction of the connecting rod and the extension direction of the fixed connecting rod are arranged along the diameter direction of the support column, and the extension direction of the connecting rod is parallel to the extension direction of the fixed connecting rod, two intermediate connecting rods are provided and are respectively hinged on the two ends in the length direction of the connecting rod, two rocking arms are provided and are respectively hinged on the two ends in the length direction of the fixed connecting rod, the other end of the intermediate connecting rod is hinged at the middle position of a rocking arm, the center of the lower end surface of the clamping plate is hinged to one end of the supporting connecting rod, and the other end of the supporting connecting rod is hinged to the other end in the length direction of the rocking arm;

[0029] At this time, the angle formed between the two clamping plates is the smallest;

[0030] (ii) load-bearing status;

[0031] The pipe is placed in the clamping area between the two clamping plates. Due to the outer wall of the pipe and its own weight, the pipe will move toward the lowest point of the clamping area along the guiding direction of the clamping plates, and the two ends of the pipe will abut against the two clamping plates. Under the gravity of the pipe, the clamping plates transmit pressure to the supporting connecting rod, and the supporting connecting rod pushes the rocker to deflect counterclockwise downward around the hinge between the rocker and the fixed connecting rod. The traction of the rocker will cause the connecting rod to move toward the fixed connecting rod, and the interval between the connecting rod and the fixed connecting rod will become smaller, causing the return spring to elastically contract. At this time, the return spring is in an energy storage state.

[0032] (iii) Reset state;

[0033] When the pipe is taken out, the reset spring will restore the interval between the connecting link and the fixed link to its initial state. At this time, the connecting link pulls the rocker arm to deflect upward clockwise around the hinge between the rocker arm and the fixed link. The rocker arm transmits the force to the supporting link, which pushes the clamping plate to retract toward the center.

[0034] According to the automatic centering method of the pipeline described in the claim, it is characterized in that a limit ring with an annular structure and located above the connecting rod is fixedly provided on the support column, and the limit ring is used to limit the upward movement of the connecting rod; a threaded rod is fixed on the connecting rod and the threaded rod extends upward and passes through the fixed connecting rod, and the threaded rod is matched with nuts a and b, nut a is located at the lower end of the fixed connecting rod, and nut b is located at the upper end of the fixed connecting rod.

[0045] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention and facilitating its implementation.

[0046] like Figure 1-4As shown, an adaptive pipe support device includes a support member 100, a clamping member 300 installed on the upper end of the support member 100 and used to support the pipe, and a connecting rod member 200 installed between the clamping member 300 and the support member 100 to adjust the opening angle of the clamping member 300; the adaptive pipe support device also includes a base 400 arranged at the bottom of the support member 100 and used to support the support member 100.

[0047] like Figure 1 As shown, when the pipeline support device provided by the present invention supports a small-diameter pipeline, the clamping member 300 adaptively adjusts the opening angle and makes the opening angle of the clamping member 300 smaller. After the pipeline is clamped, the central axis of the pipeline and the angle bisector of the clamping member 300 are located on the same vertical plane; Figure 2 As shown, when the pipe support device provided by the present invention supports a large-diameter pipe, the clamping member 300 adaptively adjusts the opening angle and makes the opening angle of the clamping member 300 larger. After the pipe is clamped, the central axis of the pipe and the angular bisector of the clamping member 300 are located on the same vertical plane. Through analysis, it can be seen that the pipe support device provided by the present invention can not only adaptively adjust the opening angle to adapt to pipes of different diameters, but also make the central axis of the pipe and the angular bisector of the clamping member 300 always located on the same vertical plane. During the processing and cutting of the pipe, the horizontality of the pipe and whether the center is accurately positioned are important factors affecting the processing. The pipe support device provided by the present invention provides a guarantee for the subsequent accurate and efficient processing of the pipe.

[0048] More specifically, Figure 1-4As shown, the support member 100 includes a vertically arranged support column 120, a horizontally placed support platform 110 is fixed on the top of the support column 120, and the clamping member 300 includes two clamping plates 310, and the clamping plates 310 are provided with two ends respectively hinged to the support platform 110 in the width direction, and the central axis of the hinge axis formed by the hinge between the clamping plates 310 and the support platform 110 is perpendicular to the central axis of the support column 120. The opening formed between the two clamping plates 310 is oriented upward and the distance between the two clamping plates 310 gradually decreases from top to bottom in the vertical direction. The connecting rod component 200 includes a supporting connecting rod 210, a rocking arm 220, an intermediate connecting rod 230, a connecting rod 240, a fixed connecting rod 250, and a return spring 260. The connecting rod 240 is slidably sleeved on the supporting column 120 and can slide along the central axis direction of the supporting column 120. The fixed connecting rod 250 is fixed to the bottom of the supporting column 120. The extending direction of the connecting rod 240 and the extending direction of the fixed connecting rod 250 are arranged along the diameter direction of the supporting column 120, and the extending direction of the connecting rod 240 is parallel to the diameter direction of the supporting column 120. The extension direction of the fixed link 250 is parallel, the return spring 260 is sleeved on the support column 120 and one end of the return spring 260 is against the fixed link 250, and the other end is against the connecting link 240, there are two intermediate links 230 and they are respectively hinged at the two ends of the length direction of the connecting link 240, there are two rocker arms 220 and they are respectively hinged at the two ends of the length direction of the fixed link 250, the other end of the intermediate link 230 is hinged to the middle position of a rocker arm 220, the center of the lower end surface of the clamping plate 310 is hinged to one end of the supporting link 210, and the other end of the supporting link 210 is hinged to the other end of the rocker arm 220 in the length direction.

[0049] When the pipe is placed in the clamping area between the clamping members 300, due to the outer wall of the pipe and its own weight, the pipe will move toward the lowest point of the clamping area along the guiding direction of the clamping plate 310, and the two ends of the pipe will abut against the two clamping plates 310; under the gravity of the pipe, the force is transmitted to the connecting rod member 200, and the pressure is transmitted from the clamping plate 310 to the supporting connecting rod 210, and the supporting connecting rod 210 pushes the rocking rod 220 to deflect counterclockwise downward around the hinge between the rocking rod 220 and the fixed connecting rod 250. The traction of the rocking rod 220 will cause the connecting rod 240 to move toward the fixed connecting rod 250. The interval between the connecting link 240 and the fixed link 250 becomes smaller and causes the return spring 260 to elastically contract. At this time, the return spring 260 is in an energy storage state; when the pipe is taken out, under the action of the return spring 260, the interval between the connecting link 240 and the fixed link 250 will be restored to the initial state, that is, the interval becomes larger. At this time, the connecting link 240 pulls the rocker 220 to deflect upward clockwise around the hinge between the rocker 220 and the fixed link 250, and the rocker 220 transmits the force to the supporting link 210. At this time, the supporting link 210 pushes the clamping plate 310 to retract toward the center.

[0050] Through the analysis of the above technical solutions, it can be known that the pipe support device provided by the present invention has pipes of the same diameter, but pipes of different materials and densities will result in different pipe weights. For example, pipe a and pipe b have the same diameter, but the mass of pipe a is less than the mass of pipe b, and the pressure exerted by pipe a on the clamping plate 310 is smaller than the pressure exerted by pipe b on the clamping plate 310. When pipe a is supported and clamped, the interval between the linkage rod 240 and the fixed rod 250 is D1, and when pipe b is supported and clamped, the interval between the linkage rod 240 and the fixed rod 250 is D2. The interval is D2, D1>D2, when pipe a is supported and clamped, the angle between the two clamping plates 310 is γ, and when pipe b is supported and clamped, the angle between the two clamping plates 310 is β, at this time β>γ, at this time, the height of pipe b in the vertical direction will be reduced relative to the height of pipe a in the vertical direction, and it can also ensure that the central axes of pipes a and pipes b are located on the bisector of the angle formed by the two clamping plates 310; the reduction in the height of the center of gravity of pipe b in the vertical direction can lower the center of gravity of the entire equipment, which is very helpful for improving the balance of the entire equipment.

[0051] More perfectly, a limiting ring having an annular structure and located above the linkage rod 240 is fixedly provided on the support column 120, and the limiting ring is used to limit the upward movement of the linkage rod 240 to avoid the opening between the two clamping plates 310 being too small, making it inconvenient to insert the pipe.

[0052] When the pipeline is successfully placed, one end of the pipeline is pulled to the processing machine for cutting and other processing. Vibration will occur when the end face of the pipeline is processed. The vibration at this time will be transmitted by the pipeline and transmitted to this equipment. Due to the influence of the vibration, this equipment will vibrate, thereby affecting the processing accuracy of the pipeline. For this reason, the present invention is also designed with a positioning and locking mechanism.

[0053] More specifically, a threaded rod is fixed on the connecting rod 240 and the threaded rod extends upward and passes through the fixed connecting rod 250. The threaded rod is matched with nuts a and b. Nut a is located at the lower end of the fixed connecting rod 250, and nut b is located at the upper end of the fixed connecting rod 250. At the construction site, the processing of pipelines is usually the same batch, that is, the pipeline sizes and specifications are the same. When the first pipeline is placed on the pipeline support device provided by the present invention, after the position is determined, the thread a and the nut b can be rotated to fix the position of the connecting rod 240, so that the distance between the connecting rod 240 and the fixed connecting rod 250 becomes a constant, so that the pipeline can obtain a more stable and reliable support environment during the processing.

[0054] More perfect, the upper end surface of the clamping plate 310 is provided with a guide groove arranged along its length direction, and the clamping plate 310 is also movably connected with a moving plate 320, which matches the guide groove and can slide along the guide direction of the guide groove, and the upper end surface of the moving plate 320 is provided with a plurality of ball grooves arranged at equal intervals along the length direction of the moving plate 320, and a limited ball is slidably matched in the ball groove. When the pipe is placed in the clamping area between the two clamping plates 310, the moving plate 320 is pushed and the limited ball is abutted against the outer wall of the pipe, and the limited ball can provide limited support for the pipe.

[0055] Another embodiment of the present invention.

[0056] The lower end surface of the clamping plate 310 is provided with a guide groove 330 extending along the length direction thereof, a sliding plate is slidably arranged in the guide groove 330, the lower end surface of the sliding plate is hinged to one end of the support link 210, and the other end of the support link 210 is hinged to the other end of the rocker 220 in the length direction, and a screw for fixing the sliding plate and the clamping plate 310 is also installed on the sliding plate, the above-mentioned support column 120 is a telescopic rod and the telescopic rod is composed of a telescopic section a and a telescopic section b, the telescopic section a is sleeved in the telescopic section b and the telescopic section a can slide along the length direction of the telescopic section b, and a locking member for locking the position of the telescopic section a and the telescopic section b is arranged between the telescopic section a and the telescopic section b. (The locking member is a conventional technology in the prior art, and will not be described in detail in the present invention. It only needs to be realized when the telescopic section a extends or contracts along the telescopic section b, to lock the position between the telescopic section a and the telescopic section b, and will not be described in detail in the present invention).

[0057] The significance of this embodiment lies in that by adjusting the height of the support column 120 and making the sliding plate adaptively adjusted, after the position adjustment is completed, the height of the support column 120 is locked with a locking component, and the position of the sliding plate is locked with a screw, so that the pipe support device provided by the present invention can adapt to pipe supports with a larger size range and a larger weight range, thereby improving adaptability.

[0058] The automatic centering method of the pipeline comprises the following steps:

[0059] (a) initial state;

[0060] The outer sleeve of the support column 120 is provided with a return spring 260, one end of the return spring 260 abuts against the fixed link 250 fixed to the bottom of the support column 120, and the other end abuts against the linkage link 240 movably provided on the support column 120. Under the elastic force of the return spring 260, the linkage link 240 abuts against the limit ring fixed to the support column 120 and located at the upper end of the linkage link 240;

[0061] A horizontally placed support platform 110 is fixed on the top of the support column 120, and the support platform 110 is connected to a clamping member 300, which includes two clamping plates 310. The clamping plates 310 are provided with two ends respectively hinged to the width direction of the support platform 110. The central axis of the hinge axis formed by the hinge between the clamping plates 310 and the support platform 110 is perpendicular to the central axis of the support column 120. The opening formed between the two clamping plates 310 faces upward and the distance between the two clamping plates 310 gradually decreases from top to bottom along the vertical direction. The extension direction of the linkage link 240 and the extension direction of the fixed link 250 are arranged along the diameter direction of the support column 120 and the extension direction of the linkage link 240 is parallel to the extension direction of the fixed link 250. Two intermediate links 230 are provided and are respectively hinged at the two ends of the length direction of the linkage link 240. Two rockers 220 are provided and are respectively hinged at the two ends of the length direction of the fixed link 250. The other end of the intermediate link 230 is hinged to the middle position of a rocker 220. The center of the lower end surface of the clamping plate 310 is hinged to one end of the support link 210, and the other end of the support link 210 is hinged to the other end of the rocker 220 in the length direction.

[0062] At this time, the angle formed between the two clamping plates 310 is the smallest;

[0063] (ii) load-bearing status;

[0064] The pipe is placed in the clamping area between the two clamping plates 310. Due to the outer wall of the pipe and its own weight, the pipe will move toward the lowest point of the clamping area along the guiding direction of the clamping plates 310, and the two ends of the pipe will abut against the two clamping plates 310. Under the gravity of the pipe, the clamping plates 310 transmit pressure to the supporting link 210, and the supporting link 210 pushes the rocking arm 220 to deflect counterclockwise downward around the hinge between the rocking arm 220 and the fixed link 250. The traction of the rocking arm 220 will cause the linkage link 240 to move toward the fixed link 250, and the interval between the linkage link 240 and the fixed link 250 will become smaller, causing the return spring 260 to elastically contract. At this time, the return spring 260 is in an energy storage state.

[0065] (iii) Reset state;

[0066] After the pipe is taken out, under the action of the return spring 260, the interval between the connecting link 240 and the fixed link 250 will be restored to the initial state. At this time, the connecting link 240 pulls the rocker arm 220 to deflect upward clockwise around the hinge between the rocker arm 220 and the fixed link 250, and the rocker arm 220 transmits the force to the supporting link 210. At this time, the supporting link 210 pushes the clamping plate 310 to retract toward the center.

[0067] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.

2. A method for automatically centering a pipeline using an adaptive pipeline support device according to claim 1, comprising the steps of: (a) initial state; A return spring (260) is sleeved on the outside of the support column (120), one end of the return spring (260) abuts against a fixed connecting rod (250) fixed to the bottom of the support column (120), and the other end abuts against a connecting rod (240) movably arranged on the support column (120); under the elastic force of the return spring (260), the connecting rod (240) abuts against a limiting ring fixed to the support column (120) and located at the upper end of the connecting rod (240); A horizontally placed support platform (110) is fixed on the top of the support column (120), the support platform (110) is connected to a clamping member (300), the clamping member (300) comprises two clamping plates (310), the clamping plates (310) are provided with two ends respectively hinged to the support platform (110) in the width direction, the central axis of the hinge axis formed by the clamping plates (310) and the support platform (110) is perpendicular to the central axis of the support column (120), The opening formed between the two clamping plates (310) faces upward and the distance between the two clamping plates (310) gradually decreases from top to bottom along the vertical direction. The extension direction of the linkage rod (240) and the extension direction of the fixed rod (250) are arranged along the diameter direction of the support column (120) and the extension direction of the linkage rod (240) is parallel to the extension direction of the fixed rod (250). Two intermediate rods (230) are provided and are respectively hinged to the two ends of the linkage rod (240) in the length direction. Two rocking rods (220) are provided and are respectively hinged to the two ends of the fixed rod (250) in the length direction. The other end of the intermediate rod (230) is hinged to the middle position of a rocking rod (220). The center of the lower end surface of the clamping plate (310) is hinged to one end of the support rod (210), and the other end of the support rod (210) is hinged to the other end of the rocking rod (220) in the length direction. At this time, the angle formed between the two clamping plates (310) is the smallest; (ii) load-bearing status; The pipe is placed in the clamping area between the two clamping plates (310). Due to the outer wall of the pipe and its own weight, the pipe moves along the guiding direction of the clamping plates (310) toward the lowest point of the clamping area, and the two ends of the pipe abut against the two clamping plates. Under the gravity of the pipe, the clamping plates (310) transmit pressure to the supporting connecting rod (210), and the supporting connecting rod (210) pushes the rocking rod (220) to deflect counterclockwise downward around the hinge between the rocking rod (220) and the fixed connecting rod (250). The traction of the rocking rod (220) causes the connecting rod (240) to move toward the fixed connecting rod (250), and the interval between the connecting rod (240) and the fixed connecting rod (250) becomes smaller, causing the return spring (260) to elastically contract. At this time, the return spring (260) is in an energy storage state. (iii) Reset state; When the pipe is taken out, the interval between the connecting link (240) and the fixed link (250) is restored to the initial state under the action of the return spring (260). At this time, the connecting link (240) pulls the rocker (220) to deflect upward clockwise around the hinge between the rocker (220) and the fixed link (250). The rocker (220) transmits the force to the supporting link (210). At this time, the supporting link (210) pushes the clamping plate (310) to retract toward the center.
