Description

Technical Field

[0001] The utility model relates to the technical field of building pipe pile manufacturing equipment, in particular to a pipe pile cover mold follower mold cleaning machine. Background Art

[0002] The pipe pile mold is a petal-type structure with upper and lower parts, including a bottom mold and a cover mold. After the pipe pile is formed and taken out, a lot of concrete lumps will remain on the mold edges of the bottom mold and the cover mold. In order not to affect the closed assembly of the cover mold and the bottom mold when they are used next time, the mold edges of the two need to be cleaned, with the mold edge of the cover mold facing down and the mold edge of the bottom mold facing up. Therefore, the structures of the mold edge cleaning equipment of the two are different; moreover, the early automated removal of concrete lumps on the mold edge was to use a round wire brush for strong brushing, but it was later discovered that the thickness of the mold edge would become thinner due to continuous wear of the wire brush, and the outer diameter of the manufactured pipe pile became smaller and smaller, which seriously affected the service life of the mold. At present, the automated cleaning equipment mainly uses a pressure wheel to crush the concrete lumps, and then combines it with a cleaning device to remove them, which can extend the service life of the mold.

[0003] However, the existing cover mold pressure wheel type mold cleaning machine still has defects, such as the "Pipe Pile or Pole Cover Mold Tongue Cleaning and Oiling Device" disclosed in Chinese Patent Publication No. CN210633821U. The defects are mainly reflected in: First, because the cover mold will inevitably deviate left and right during transportation, the pressure wheels are densely arranged, which increases the manufacturing cost and use cost of the equipment; Second, the pressure wheel is a combination of lifting and spring pressure, and the movable parts related to lifting are located below the pressure wheel. Therefore, its movable surface is prone to adhere to falling dust, or dust accumulates in the spring chamber, which will cause the lifting movement of the pressure wheel to malfunction; Third, the soil blocks crushed by the pressure wheel cannot be collected and cleaned after falling, causing great inconvenience to users. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to solve the problem that the existing pipe pile cover and mold cleaning machine has high equipment manufacturing cost and high use and maintenance cost due to the structural defects of the pressure wheel assembly, a pipe pile cover and mold cleaning machine is provided.

[0005] The utility model solves the technical problem by adopting the following technical solution: a pipe pile cover mold follower mold cleaning machine, comprising a frame, with the cover mold movement direction as the front, and a left side transverse moving component and a right side transverse moving component symmetrically arranged on the frame;

[0006] The left side lateral movement assembly and the right side lateral movement assembly are driven by a driving cylinder and are arranged on the support beam of the frame in a left-right sliding manner. The left side lateral movement assembly and the right side lateral movement assembly move toward each other when the mold cleaning stops, and move away from each other when the mold cleaning starts.

[0007] The left and right transverse moving assemblies respectively include a slide, a positioning wheel mounting plate, a positioning wheel, a pressure wheel mounting plate and a pressure wheel, the axes of the positioning wheel and the pressure wheel are horizontal in the left and right directions, the slide is designed to slide on the support beam and is connected to the movable end of the drive cylinder, the positioning wheel mounting plate is mounted on the slide, the positioning wheel is rotatably arranged on the positioning wheel mounting plate, the pressure wheel mounting plate is driven by a swing device to rotate in the form of up and down swinging and is arranged on the slide, the pressure wheel is rotatably arranged on the pressure wheel mounting plate, and the positioning wheel is located on the inner side of the pressure wheel;

[0008] When the left side transverse moving assembly and the right side transverse moving assembly start to move away from each other for clearing the mold, that is, when the left side transverse moving assembly moves to the left and the right side transverse moving assembly moves to the right, the outer side wall of the positioning wheel abuts against the inner wall of the cover mold close to the mold edge for positioning, and then the raised pressure wheel presses against the mold edge and crushes the concrete lumps on the mold edge.

[0009] Specifically, the mold cleaning machine has an electronic control device, which includes a position sensor for identifying the position of the cover mold. The electronic control device controls the movement of the driving cylinder and the swinging device according to the signal of the position sensor.

[0010] Specifically, the mold cleaning machine of the present invention is used on the conveyor line of the cover mold. Although there are rollers on the conveyor line at the front and rear sides of the mold cleaning machine, in order to ensure the mold cleaning effect and facilitate the installation of the mold cleaning machine, the front and rear ends of the frame are respectively provided with front rollers and rear rollers supporting the cover mold, and the left side lateral movement assembly and the right side lateral movement assembly are located between the front rollers and the rear rollers.

[0011] Specifically, since there is a working process of positioning first and then starting the pressure wheel when starting work, in order to ensure that the mold edge at the front end of the cover mold can be cleaned, the positioning wheel mounting plate has two positioning wheels arranged in front and back, and each positioning wheel has a pressure wheel on the outside.

[0012] Specifically, the left side transverse moving assembly and the right side transverse moving assembly respectively have two or more sets of pressure wheels, pressure wheel mounting plates and swing driving devices.

[0013] Specifically, the swing driving device includes a swing driving cylinder and a return spring, and the swing driving cylinder drives the pressure wheel mounting plate to swing upward or drives the pressure wheel mounting plate to swing downward.

[0014] Specifically, in order to improve the stability and rigidity of the left and right transverse moving assemblies during movement, a stabilizing beam is further provided on the frame, and the upper sliding portion of the slide is slidably arranged on the support beam, and the lower sliding portion is slidably arranged on the stabilizing beam.

[0015] Specifically, in order to better cope with the left and right deviations of the transported cover mold, the left lateral movement assembly and the right lateral movement assembly are respectively driven by a driving cylinder, and the two driving cylinders exert equal forces on the left and right movements of the left lateral movement assembly and the forces on the right and left movements of the right lateral movement assembly.

[0016] The beneficial effects of the present invention are as follows: the pipe pile cover formwork follower mold cleaning machine provided by the present invention crushes the concrete lumps on the mold edges on both sides of the cover formwork by arranging left and right side transverse moving components; the pressing wheel moves transversely with the positioning wheel, and the positioning wheel is positioned by using the inner wall of the cover formwork, without intensively arranging too many pressing wheels, thereby reducing the manufacturing and use costs of the equipment; combined with the structure of the pressing wheel swinging and lifting, a spacious dust collecting and cleaning space is formed under the pressing wheel, making equipment maintenance more convenient.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments.

[0027] In the description of the present invention, in terms of direction, the direction of movement of the cover mold is the front and longitudinal direction, the horizontal direction perpendicular to the direction of movement of the cover mold is the left and right direction and the lateral direction, and the vertical direction perpendicular to the direction of movement of the cover mold is the up and down direction; in the definition of "inside" and "outside", the central axis of the mold cleaning machine in the front and back direction is the innermost side, and the vertical plane containing the central axis is the dividing line between the left and right.

[0028] As attached Figure 1 and 2 A pipe pile cover mold follower type mold cleaning machine is provided with a frame 1, with the movement direction of the cover mold 20 as the front, and a left side lateral movement component 2 and a right side lateral movement component 3 are provided on the frame 1 in a left-right symmetrical form. The left side lateral movement component 2 is used to clean the left side of the cover mold 20, and the right side lateral movement component 3 is used to clean the right side of the cover mold 20. The front and rear ends of the frame 1 are respectively provided with a front roller 11 and a rear roller 12 supporting the cover mold 20. The left side lateral movement component 2 and the right side lateral movement component 3 are located between the front roller 11 and the rear roller 12. When the mold cleaning machine is installed on the conveyor line of the cover mold 20, the front roller 11 and the rear roller 12 are flush with the bearing surfaces of other rollers on the conveyor line, and the structures of the front roller 11 and the rear roller 12 are the same. Figure 7 The structure of the front roller 11 is shown schematically.

[0029] The left side lateral movement assembly 2 and the right side lateral movement assembly 3 are driven by the driving cylinder 4 to slide left and right on the support beam 1-1 of the frame 1. Figure 6 The diagram shows the driving state of the driving cylinder 4. The left side transverse moving assembly 2 and the right side transverse moving assembly 3 move toward each other when the mold cleaning stops and move away from each other when the mold cleaning starts. The states of stopping mold cleaning and starting mold cleaning are shown in the attached diagram. Figure 3 and attached Figure 2The left side transverse moving assembly 2 and the right side transverse moving assembly 3 are respectively driven by a driving cylinder 4.

[0030] The left side transverse moving assembly 2 and the right side transverse moving assembly 3 respectively include a slide 5, a positioning wheel mounting plate 6, a positioning wheel 7, a pressure wheel mounting plate 8 and a pressure wheel 9, as shown in the attached drawings. Figure 4 As shown, the axis of the positioning wheel 7 and the axis of the pressure wheel 9 are horizontal left and right, the slide 5 is designed to slide on the support beam 1-1 and is connected to the movable end of the drive cylinder 4, the fixed end of the drive cylinder 4 is fixed on the frame 1, the positioning wheel mounting plate 6 is installed on the slide 5, the positioning wheel 7 is rollingly set on the positioning wheel mounting plate 6, the pressure wheel mounting plate 8 is driven by the driving swing device 10 to rotate in the form of up and down swinging on the slide 5, the pressure wheel 9 is rollingly set on the pressure wheel mounting plate 8, and the positioning wheel 7 is located on the inner side of the pressure wheel 9.

[0031] When the left side lateral moving assembly 2 and the right side lateral moving assembly 3 start to move away from each other during the mold cleaning, that is, when the left side lateral moving assembly 2 moves to the left and the right side lateral moving assembly 3 moves to the right, the outer wall of the positioning wheel 7 abuts against the inner wall of the cover mold 20 near the mold edge for positioning, and then the raised pressing wheel 9 presses against the mold edge and crushes the concrete lumps on the mold edge, as shown in FIG. Figure 5 shown.

[0032] The two driving cylinders 4 exert equal forces on the left and right movements of the left lateral movement component 2 and the right and left movements of the right lateral movement component 3. In this way, even if the cover mold 20 has a certain amount of left and right offset, the left lateral movement component 2 and the right lateral movement component 3 can be positioned at the left and right mold edges after movement.

[0033] The mold cleaning machine has an electronic control device, which includes a position sensor for identifying the position of the cover mold 20. The electronic control device controls the movement of the driving cylinder 4 and the swinging device 10 according to the signal of the position sensor.

[0034] The positioning wheel mounting plate 6 is provided with two positioning wheels 7 arranged front and back, and each positioning wheel 7 has a pressure wheel 9 on the outside. Figure 4 It is shown that two groups of pressure wheels 9 are provided on the outside of the front positioning wheel 7, and one group of pressure wheels 9 is provided on the outside of the rear positioning wheel 7, that is, the left side transverse movement component 2 and the right side transverse movement component 3 respectively have three sets of pressure wheels 9, pressure wheel mounting plates 8 and driving swing devices 10, each pressure wheel mounting plate 8 is installed with a pressure wheel 9 or a group of pressure wheels 9, each pressure wheel mounting plate 8 is driven by a driving swing device 10, two or more coaxial pressure wheels 9 are a group of pressure wheels 9, and the spacing structure between each pressure wheel 9 in a group of pressure wheels 9 is more conducive to crushing concrete lumps.

[0035] As attached Figure 1As shown, the swing driving device 10 includes a swing driving cylinder 10-1 and a return spring 10-2. The swing driving cylinder 10-1 drives the pressure wheel mounting plate 8 to swing up or down. Figure 1 The middle return spring 10 - 2 is a tension spring, one end of which is positioned on the extended end of the pressure wheel mounting plate 8 passing the rotation center, and the other end is positioned on the slide 5 .

[0036] Still see attached Figure 6 As shown, a stabilizing beam 1-2 is also provided on the frame 1, the upper sliding portion of the slide 1 is set on the supporting beam 1-1, and the lower sliding portion is set on the stabilizing beam 1-2. The sliding between the slide 1 and the supporting beam 1-1 is achieved by a number of distributed bearings, and the sliding between the slide 1 and the stabilizing beam 1-2 is achieved by an oil-containing wear-resistant bushing.

[0037] The simple working process of this utility model is:

[0038] When the front end of the cover mold 20 moves forward to the rear positioning wheel 7, the position sensor of the electronic control device sends a signal to the electronic control device to drive the driving cylinder 4 to drive the left side transverse moving component 2 to move to the left and the right side transverse moving component 3 to move to the right, so that the positioning wheel 7 on the component abuts against the inner wall of the cover mold close to the mold edge. The electronic control device then controls the driving swing device 10 to move, the driving swing cylinder 10-1 is released, and the return spring 10-2 pulls the pressure wheel mounting plate 8 to make the pressure wheel 9 rise and press toward the mold edge. The driving swing cylinder 10-1 and The return spring 10-2 can also be repositioned. The pressure wheel 9 is raised by the swing cylinder 10-1, and the pressure wheel 9 is lowered by the return spring 10-2. When the rear end of the cover mold 20 moves out of the pressure wheel 9, the position sensor sends a signal to make the electronic control device drive the drive cylinder 4 to drive the left side transverse movement component 2 to move to the right and the right side transverse movement component 3 to move to the left, and the two components are close to each other. At the same time, the electronic control device controls the swing device 10 to move to make the pressure wheel 9 lower and wait for the next cover mold 20 to be processed.

[0039] The form in which the positioning wheel mounting plate 6 is installed on the slide 5 can be a fixed installation (when processing one type of cover mold), or a height-adjustable installation, or the positioning wheel mounting plate 6 can be driven by another swing device to be installed on the slide 5 in a lifting manner, rising when positioning is required and lowering when positioning is not required (processing different types of cover molds, different specifications or different square pipe pile cover molds and round pipe pile cover molds). The outer edge of the outer side wall of the positioning wheel 7 is suitably set to a shape similar to the inner wall of the cover mold 20.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
