[0002] In the production process of the steel-reinforced plastic composite pipe straight pipe production line, the extruder slides on the steel rail through the guide rollers on the steel rail.

[0003] However, in actual operation, due to insufficient rigidity of the extruder body, resonance inevitably occurs in the motor, reducer, and screw during extrusion. Furthermore, the adjustable support rail guide rollers of the extruder use a free-line surface contact method with the rails without an effective locking device, causing the extruder to vibrate. As the operating conditions continue, the vibration source will increase with the running time, resulting in uncontrollable vibration amplitude. This leads to production line shutdowns, wasted raw materials, and a sharp increase in material and labor costs. Utility Model Content

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] refer to Figure 1-8 A guide rail clamping device for a plastic extruder is provided, located between the extruder base 1 and the steel rail 2. Multiple guide rail clamping devices can be symmetrically arranged between the extruder base 1 and the steel rail 2 to improve the uniformity of clamping force, thereby enhancing the stability of the extruder. The guide rail clamping device includes a clamping structure 3, a support base 4, and a connecting structure 5. The clamping structure 3 is directly clamped onto the steel rail 2, forming a rigid clamping fixation with the steel rail 2, providing a fixed reference for the device. The support base 4 is fixed on the side of the extruder base 1 near the steel rail 2, and can bear the load of the extruder base 1. The connecting structure 5 is located between the clamping structure 3 and the support base 4, connecting the clamping structure 3 and the support base 4 to achieve a stable force transmission path between the two.

[0019] In some embodiments, the clamping structure 3 includes a first clamping block 31, a second clamping block 32, two clamping grooves 33, and a clamping assembly. The first clamping block 31 is the basic bearing block of the clamping structure 3, located on the side of the rail 2 near the extruder base 1, with its top abutting against the connecting structure 5 to transmit the force between the clamping structure 3 and the support base 4. The second clamping block 32 cooperates with the first clamping block 31 to form a clamping structure, located on the side of the rail 2 away from the extruder base 1, and secures the rail 2 by clamping it relative to the first clamping block 31. Both the first clamping block 31 and the second clamping block 32 can be forged from 45# steel. After heat treatment, sufficient rigidity and wear resistance are ensured. Two clamping grooves 33 are respectively set on the side surfaces of the first clamping block 31 and the second clamping block 32, which are close to each other. After the two clamping grooves 33 are joined together, they form a receiving space that matches the rail 2. The rail 2 is placed between the two clamping grooves 33, which can increase the contact area between the first clamping block 31, the second clamping block 32 and the rail 2, avoid the concentrated clamping force that causes damage to the surface of the rail 2, and prevent the clamping structure 3 from sliding along the length of the rail 2. The clamping assembly is set between the first clamping block 31 and the second clamping block 32. By actively applying force, the two clamping blocks are brought closer to the rail 2 to achieve clamping and fixation.

[0020] In some embodiments, the clamping assembly includes two first through holes 34, two first threaded holes 35, and two clamping screws 36. The two first through holes 34 are symmetrically arranged and pass through the second clamping block 32 to ensure that the clamping screws 36 can pass through smoothly. The two first threaded holes 35 correspond one-to-one with the two first through holes 34, and the first threaded holes 35 pass through the first clamping block 31. Their inner diameter and thread specifications are matched with the clamping screws 36 to form a screwed engagement with the clamping screws 36. The two clamping screws 36 are clamping force actuators. The clamping screws 36 can be hexagonal screws. One end of the clamping screw 36 passes through the first through hole 34, and the other end is screwed into the first threaded hole 35.

[0021] When the clamping screw 36 is tightened, the first clamping block 31 and the second clamping block 32 approach each other under the action of the thread thrust until the inner walls of the two clamping grooves 33 are tightly fitted with the rail 2, thus achieving clamping; loosening the clamping screw 36 can release the clamping, allowing the extruder to slide on the rail 2.

[0022] In some embodiments, the clamping assembly further includes a positioning groove 37, which is located on the side of the first clamping block 31 away from the extruder base 1. The groove size matches the outer dimensions of the second clamping block 32, and the second clamping block 32 is placed exactly in the positioning groove 37. This can increase the contact area between the first clamping block 31 and the second clamping block 32, and at the same time restrict the vertical movement of the second clamping block 32, thereby ensuring the stable clamping of the clamping structure 3 on the rail 2.

[0023] In some embodiments, the support base 4 includes two fixed base plates 41 and a support plate 42. The two fixed base plates 41 are the connecting carriers between the support base 4 and the extruder base 1. The two fixed base plates 41 are symmetrically arranged on the side of the extruder base 1 near the rail 2. The fixed base plates 41 can be square plates, and their shape and size can match the channel steel on the side of the extruder base 1. They can be fixed in the channel steel by welding. The support plate 42 is the mounting carrier of the connecting structure 5. The support plate 42 is fixed on the side of the two fixed base plates 41 near the rail 2. The support plate 42 is provided with the connecting structure 5 to realize the fixed connection between the support base 4 and the clamping structure 3.

[0024] In some embodiments, the support base 4 further includes two reinforcing plates 43. The fixed base plate 41, the support plate 42, and the reinforcing plates 43 can all be made of Q235 steel plate. The two reinforcing plates 43 are respectively disposed between the two fixed base plates 41 and the support plate 42 and can be welded and fixed. The reinforcing plates 43 can adopt a right-angled triangular structure. Through the stability characteristics of the triangle, the overall rigidity of the support base 4 is improved, the vibration resistance of the support base 4 is enhanced, and the vibration of the extruder operation is prevented from causing the connection between the support plate 42 and the fixed base plate 41 to loosen or break.

[0025] In some embodiments, the connecting structure 5 includes a connecting screw 51, a connector 52, and a connecting nut 53. The connecting screw 51 is fixed to the top of the first clamping block 31 and can be welded or integrally formed. Its axis is perpendicular to the top surface of the first clamping block 31, providing an assembly reference for the connector 52. The connector 52 is sleeved on the connecting screw 51 and is fixedly connected to the support plate 42. The connector 52 can transfer the load of the support plate 42 to the connecting screw 51 and then to the first clamping block 31. The connecting nut 53 is screwed into the connecting screw 51 and pressed onto the top surface of the connector 52. By tightening the connecting nut 53, the connector 52 can be locked onto the connecting screw 51, thereby achieving a fixed connection between the connecting structure 5 and the support plate 42. There can be two connecting nuts 53. The double nuts can improve the connection stability between the connecting screw 51 and the connector 52, thereby improving the vibration resistance.

[0026] In some embodiments, the connecting structure 5 further includes a second through hole 54, two third through holes 55, two second threaded holes 56, and two locking screws 57. The second through hole 54 penetrates the middle of the connector 52, and its inner diameter is slightly larger than the outer diameter of the connecting screw 51. For example, if the outer diameter of the connecting screw is 24 mm, the diameter of the second through hole is 25 mm, which facilitates the insertion and engagement of the connector 52 and the connecting screw 51. The two third through holes 55 symmetrically penetrate both ends of the connector 52, providing an installation channel for the locking screws 57. The two second threaded holes 56 penetrate the support plate 42 and are coaxially arranged with the two third through holes 55. Their thread specifications match those of the locking screws 57. One end of the locking screw 57 passes through the third through hole 55, and the other end is screwed into the second threaded hole 56. By tightening the locking screws 57, the connector 52 and the support plate 42 can be firmly fixed to prevent relative displacement due to vibration.

[0027] In some embodiments, the connecting structure 5 further includes a screw sleeve 58 and a clearance hole 59. The screw sleeve 58 is located in the middle of the connector 52. The connector 52 and the screw sleeve 58 can be integrally formed from 45# steel. The screw sleeve 58 has a second through hole 54 through it. The screw sleeve 58 can increase the contact area between the connector 52 and the connecting screw 51, thereby enhancing the stability of the fit between the connector 52 and the connecting screw 51. The clearance hole 59 penetrates the support plate 42 on the side away from the fixed base plate 41, and the screw sleeve 58 is located in the clearance hole 59. The screw sleeve 58 is exactly placed in the clearance hole 59. The clearance hole 59 can be a U-shaped hole. The clearance hole 59 can provide room for the screw sleeve 58 to move, which is convenient for fine-tuning the position of the connector 52 during installation, and ensures that the third through hole 55 and the second threaded hole 56 are accurately aligned.

[0028] The specific working principle is as follows: By welding, two fixed base plates 41 are symmetrically fixed in a suitable position on the channel steel near the rail 2 on the side of the extruder base 1, so as to achieve a fixed connection between the support base 4 and the extruder base 1.

[0029] Clean the impurities and oil stains from the surfaces of the extruder base 1 and the rail 2 to ensure the installation surfaces are clean; place the first clamping block 31 on the side of the rail 2 closest to the extruder base 1, so that one side of the rail 2 is embedded in the clamping groove 33 of the first clamping block 31; at the same time, pass the connecting screw 51 at the top of the first clamping block 31 through the clearance hole 59; put the connecting piece 52 with the screw sleeve 58 on it onto the connecting screw 51 through the second through hole 54, and make the screw sleeve 58 extend into the clearance hole 59 of the support plate 42. 9. Adjust the position of the connector 52 so that the third through holes 55 at both ends of the connector 52 are aligned with the second threaded holes 56 on the support plate 42. Pass the locking screw 57 through the third through hole 55 and screw it into the second threaded hole 56 to achieve a firm connection between the connector 52 and the support plate 42. Finally, screw the connecting nut 53 into the connecting screw 51 and tighten the connecting nut 53 so that the connecting nut 53 is pressed onto the connector 52 to prevent the connector 52 from sliding along the connecting screw 51.

[0030] Then, the second clamping block 32 is placed into the positioning groove 37 of the first clamping block 31, so that the other side of the rail 2 is embedded in the clamping groove 33 of the second clamping block 32; finally, the clamping screw 36 is passed through the first through hole 34 and screwed into the first threaded hole 35, and the clamping screw 36 is pre-tightened so that the first clamping block 31 and the second clamping block 32 firmly clamp the rail 2 through the clamping groove 33. At this time, the clamping structure 3 and the rail 2 form a fixed connection that cannot slide relative to each other.

[0031] When the extruder is running, the vibrations generated by components such as the motor, reducer, and screw are transmitted to the support base 4 through the extruder base 1. The support base 4, through the triangular stabilizing structure formed by the reinforcing plate 43, disperses the vibrations to the fixed base plate 41 and the support plate 42, avoiding local stress concentration. Subsequently, the vibrations are transmitted to the connecting structure 5 through the support plate 42. The connecting structure 5, through the double locking of the locking screw 57 and the connecting nut 53, transmits the vibrations to the clamping structure 3. Since the clamping structure 3 is firmly clamped to the rail 2 by the clamping screw 36, the vibrations are ultimately absorbed by the rail 2, effectively suppressing the vibration of the extruder and preventing the vibration amplitude from increasing with the length of the running time, thus ensuring the continuous and stable operation of the production line.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
