Description

Technical Field

[0001] The invention relates to the technical field of roughening construction in construction, in particular to a roughening device for prefabricated components. Background Art

[0002] In the prior art, the hollow slab beam double-sided walking type roughening device is mainly used. Figure 1 As shown, it includes a traveling frame, an adjusting frame and a haircutting machine. A plurality of traveling wheels driven by a driving motor to rotate synchronously are installed at the bottom of the traveling frame. A guide frame is installed on the traveling frame and a second guide rail is arranged on the guide frame. Two adjusting frames are respectively arranged on both sides of the traveling frame and are respectively driven by transverse hydraulic cylinders to adjust according to the second guide rail. A movable plate is installed on the adjusting frame. The movable plate is driven by a longitudinal hydraulic cylinder to be longitudinally adjusted along the first guide rail. A mounting plate with an adjustable plate surface angle is movably arranged on the movable plate. The haircutting machine is fixed on the mounting plate, and limiting wheels for limiting the travel direction of the equipment are fixed on both sides of the mounting plate located on opposite sides of the haircutting machine.

[0003] Specifically, refer to the attached Figure 1 As shown, the chiseling device in the prior art has the following problems:

[0004] 1. This technology has high requirements on the top of the hollow slab, such as no outward ribs on the top of the hollow slab, the top of the hollow slab is wide, the cross-section flatness and levelness of the top of the hollow slab are high, etc. And the trolley must be placed parallel to the hollow slab.

[0005] 2. Using a hydraulic system as an adjusting device requires a complete set of hydraulic systems, which will cause hydraulic oil pollution.

[0006] 3. After finishing the roughening of a hollow slab, it is necessary to use a lifting device to move the trolley to other hollow slabs, which is rather cumbersome.

[0007] 4. It does not have the function of single-sided roughening. Summary of the invention

[0008] The purpose of the present invention is to provide a roughening device for prefabricated components which has low requirements on supporting equipment and the like, can realize angle adjustment, and can spray water during construction.

[0009] To achieve the above objectives, the present invention is implemented through the following technical means.

[0010] A roughening device for prefabricated components, comprising:

[0011] A walking unit, wherein a first track for the walking unit to walk is provided at the bottom of the walking unit;

[0012] A connecting frame is arranged along the width direction of the walking unit and across the walking unit, and a lifting unit is connected below the connecting frame;

[0013] A transmission assembly, wherein the transmission assembly is linked with the lifting unit, and when the lifting unit drives the haircutting machine to rise and fall, the transmission unit drives the haircutting machine to approach or move away from the prefabricated component;

[0014] Telescopic cylinders for the haircutting machine are respectively arranged along the lifting unit and the connecting frame. The telescopic cylinders are used for air supply to the haircutting machine. The telescopic cylinders are extended and retracted as the lifting unit rises and falls and the haircutting machine moves away from or close to the prefabricated component.

[0015] In this technical solution, the connecting frame is arranged across the width direction of the walking unit, so as not to affect the independent walking of the walking unit, and provides a basis for the movement of the entire large equipment of the haircutting machine, that is, it can be achieved through the movement of the walking unit, thereby saving the track setting in one direction.

[0016] In the technical solution, the transmission components are linked to achieve movement in two directions at the same time, that is, it can kill two birds with one stone. Combined with the walking unit, it can meet the adjustment in three directions, so that the hair cutting machine can have displacement in three directions in three-dimensional space.

[0017] In the technical solution, a telescopic cylinder is used for air supply, and fewer pipelines are set up. At the same time, the telescopic cylinder can be extended and retracted accordingly with the adjustment of the haircutting machine, so that the pipeline setting is variable, avoiding the occurrence of problems such as line entanglement.

[0018] As a further improvement of the present invention, the connecting frame extends downward to form a second track perpendicular to the connecting frame, and the lifting unit is lifted and lowered along the second track.

[0019] In the technical solution, a second track is arranged below the connecting frame. At this time, the second track is a lifting track, and the lifting is located below the traveling unit. When lifting, there will be no conflict with the traveling unit and the connecting frame, thereby improving efficiency.

[0020] As a further improvement of the present invention, the connecting frame is provided with a third track toward the length direction of the walking unit, and the adjustment unit on the third track is linked with the lifting unit on the second track to achieve simultaneous adjustment of two directions of the haircutting machine.

[0021] In the present technical solution, a third track is arranged on the connecting frame in the length direction of the traveling unit. At this time, the three tracks are perpendicular to each other, thereby realizing the control of three angles. At the same time, since the traveling unit is generally an existing operating equipment, in order to avoid affecting it, the two rear tracks are linked so as not to affect the operation of the existing equipment.

[0022] As a further improvement of the present invention, the lifting unit is a movable leg arranged in the second track, and the movable leg moves along the telescopic axis along the third track at the bottom of the walking unit.

[0023] In this technical solution, the movable leg is raised and lowered along the second track, and the second track is unchanged. The height can be adjusted in conjunction with the movable leg. For example, the movable leg is located in the second track at a certain length, and the movable leg moves downward to form the length of the movable leg plus the second track. At this time, the entire length is relatively long, but the haircutting machine is located at the lowest point. Further, a telescopic shaft is added, and two movable legs can be set at this time to make them move horizontally along the telescopic shaft, that is, the two movable legs are close to or away from each other, and the distance between the two haircutting machines is adjusted.

[0024] As a further improvement of the present invention, a frame structure is provided in the walking unit, a transmission rack is provided in the frame structure, a trolley with gear wheels is provided on the transmission rack, and the gear rotates along the transmission rack to realize the movement of the trolley.

[0025] In this technical solution, a trolley is set to drive the vehicle. When the power of the gear is insufficient, the power can be increased to drive the horizontal movement. Compared with other structures, the movement of the trolley is easier to control and realize, especially within the frame, and it does not affect other equipment, saving space.

[0026] As a further improvement of the present invention, the second track is connected to the trolley, the lifting unit is a gear transmission assembly, and the gear transmission assembly is meshed with the gear.

[0027] In the technical solution, meshing is utilized, and during the meshing process, the direction of force can be adjusted and driven at the same time, so that one power can be used to drive the movement adjustment in two directions, thus saving power and achieving multi-directional driving at the same time.

[0028] As a further improvement of the present invention, it also includes an angle adjustment unit, which drives the hair cutting machine to rotate along the second track to adjust the working angle of the hair cutting machine.

[0029] In the present technical solution, the rotation of the second track is utilized. At this time, the second track can be made of channel steel, and the second track itself has a certain groove structure, which can limit the rotation range of the chiseling machine. Combined with various limit positions located at the upper and lower parts of the chiseling machine, the entire angle range can be accurately adjusted.

[0030] As a further improvement of the present invention, the angle adjustment unit is arranged on the haircutting machine along the second track and passes through the second track.

[0031] In the technical solution, the angle adjustment unit passes through the second track, so that the staff can directly manually control the adjustment of the roughening angle and further fine-tune it, etc., which has higher accuracy for structures such as rounded corners.

[0032] As a further improvement of the present invention, it further comprises a spray unit, which is arranged above the haircutting machine and close to the second track.

[0033] In the technical solution, a spray unit is provided, and a second track is provided, so that it can be raised and lowered along the second track and is located above the haircutting machine. Therefore, it can always be near the haircutting machine, fixed on the haircutting machine, and move accordingly.

[0034] As a further improvement of the present invention, the spray unit is connected to a water source via a bellows.

[0035] In the present technical solution, a bellows is used as the water pipe, which can avoid entanglement of the pipeline, etc. The bellows is relatively strong and can meet the water flow of a certain water pressure, thus saving the installation space of the components in the haircutting machine and avoiding line entanglement, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0049] Example 1

[0050] Refer to the attached Figure 1-10 As shown, a roughening device for prefabricated components in this embodiment includes:

[0051] A walking unit 20, wherein a first track 1 for the walking unit 20 to walk is provided at the bottom of the walking unit 20;

[0052] A connecting frame is provided along the width direction of the walking unit 20 and across the walking unit, and a lifting unit 16 is connected to the bottom of the connecting frame;

[0053] A transmission assembly, wherein the transmission assembly is linked with the lifting unit 16. When the lifting unit drives the haircutting machine 10 to rise and fall, the transmission unit drives the haircutting machine 10 to move closer to or away from the prefabricated component 200;

[0054] Telescopic cylinders for the roughing machine 10 are respectively arranged along the lifting unit 16 and the connecting frame. The telescopic cylinders are used for air supply to the roughing machine 10. The telescopic cylinders are extended and retracted as the lifting unit 16 is raised and lowered and the roughing machine 10 moves away from or close to the prefabricated component.

[0055] In this embodiment, the connecting frame is arranged across the width direction of the walking unit, so as not to affect the independent walking of the walking unit, and provides a basis for the movement of the entire large equipment of the haircutting machine, that is, it can be achieved through the movement of the walking unit, thereby saving the track setting in one direction.

[0056] In this embodiment, the transmission components are linked to achieve movement in two directions at the same time, that is, it can kill two birds with one stone. Combined with the walking unit, it can meet the adjustment in three directions, so that the haircutting machine can have displacement in three directions in three-dimensional space.

[0057] In this embodiment, a telescopic cylinder is used for air supply, and fewer pipelines are required. At the same time, the telescopic cylinder can be extended and retracted accordingly with the adjustment of the haircutting machine, so that the pipeline setting is variable, thereby avoiding problems such as line entanglement.

[0058] Example 2

[0059] In this embodiment, the connection relationship of each structure is mainly introduced.

[0060] As shown in the accompanying drawings, the connecting frame extends downward to form a second track 18 perpendicular to the connecting frame, and the lifting unit 16 is lifted and lowered along the second track 18 .

[0061] In this embodiment, a second track is set below the connecting frame. At this time, the second track is a lifting track, and the lifting is located below the walking unit. When lifting, there will be no conflict with the walking unit and the connecting frame, thereby improving efficiency.

[0062] The connecting frame is provided with a third track in the length direction of the walking unit 20, and the adjustment unit on the third track is linked with the lifting unit 16 on the second track 18 to achieve simultaneous adjustment of two directions of the hair cutting machine.

[0063] In this embodiment, a third track is set on the connecting frame toward the length direction of the walking unit. At this time, the three tracks are perpendicular to each other, thereby realizing the control of three angles. At the same time, since the walking unit is generally an existing running equipment, in order to avoid affecting it, the rear two tracks are linked so as not to affect the operation of the existing equipment.

[0064] Furthermore, the lifting unit 16 is a movable leg 14 disposed in the second track 18 , and the movable leg 14 moves along the telescopic shaft 50 at the bottom of the walking unit 20 along the third track.

[0065] In this embodiment, the movable leg is raised and lowered along the second track, and the second track is unchanged, and the height can be adjusted in conjunction with the movable leg. For example, the movable leg is located in the second track at a certain length, and the movable leg moves downward to form the length of the movable leg plus the second track. At this time, the entire length is relatively long, but the haircutting machine is located at the lowest point. Further, a telescopic shaft is added, and two movable legs can be set at this time to make them move horizontally along the telescopic shaft, that is, the two movable legs are close to or away from each other, and the distance between the two haircutting machines is adjusted.

[0066] Specifically, a frame structure is provided in the walking unit 20 , a transmission rack 21 is provided in the frame structure, a trolley 6 with gear wheels is provided on the transmission rack 21 , and the gear rotates along the transmission rack 21 to realize the movement of the trolley 6 .

[0067] In this embodiment, a trolley is provided to drive the vehicle. When the power of the gear is insufficient, the power can be increased to drive the horizontal movement. Compared with other structures, the movement of the trolley is easier to control and realize, especially within the frame, and it does not affect other equipment, thus saving space.

[0068] As shown in the accompanying drawings, the second track 18 is connected to the trolley 6, and the lifting unit 16 is a gear transmission assembly, and the gear transmission assembly is engaged with the gear.

[0069] In this embodiment, meshing is utilized, and during the meshing process, the direction of force can be adjusted and driven at the same time, so that one power can be used to drive the movement adjustment in two directions, thus saving power and achieving multi-directional driving at the same time.

[0070] In order to achieve the roughening of curved corners, etc., an angle adjustment unit 30 is also included. The angle adjustment unit 30 drives the roughening machine to rotate along the second track 18 to adjust the working angle of the roughening machine 10.

[0071] In this embodiment, the rotation of the second rail is utilized. At this time, the second rail can be made of channel steel, and the second rail itself has a certain groove structure, which can limit the rotation range of the chiseling machine. Combined with various limit positions located at the upper and lower parts of the chiseling machine, the entire angle range can be accurately adjusted.

[0072] Specifically, along the second track 18 , the angle adjustment unit 30 is disposed on the haircutting machine 10 and passes through the second track 18 .

[0073] In this embodiment, the angle adjustment unit passes through the second track, so that the staff can directly manually control the adjustment of the roughening angle and further fine-tune it, etc., which has higher accuracy for structures such as rounded corners.

[0074] Furthermore, it also includes a spray unit 40 , which is arranged above the haircutting machine 10 and close to the second track 18 .

[0075] In this embodiment, a spray unit is provided, and a second track is provided, so that it can be raised and lowered along the second track and is located above the haircutting machine. Therefore, it can always be near the haircutting machine, fixed on the haircutting machine, and move accordingly.

[0076] Furthermore, the spray unit 40 is connected to a water source via a bellows.

[0077] In this embodiment, a bellows is used as the water pipe, which can avoid entanglement of the pipeline, etc. The bellows is relatively strong and can meet the water flow of a certain water pressure, saving the installation space of the components in the haircutting machine and avoiding line entanglement, etc.

[0078] Example 3

[0079] In this embodiment, the movement process in the Y-axis direction such as lifting and lowering is mainly described.

[0080] See attached Figure 1 and 4 As shown, a roughening device for prefabricated components in this embodiment includes:

[0081] Hair cutting machine 10,

[0082] A walking unit 20, wherein the walking unit 20 at least forms a clearance space 100, and the haircutting machine 10 is lifted and lowered in the Y-axis direction during operation along the height direction of the walking unit 20;

[0083] Specifically, a track for fixing the haircutting machine is provided on the walking unit 20, and the haircutting machine moves up and down along the track of the haircutting machine in order to prepare for the later stage.

[0084] In this embodiment, due to the addition of a spray unit, spraying can be achieved during the roughening process, that is, water mist can be sprayed during the work, reducing the harm of dust to the environment and the operator, and making the use safer. Specifically, a shower or a spray device can be selected as the spray unit, and then connected to a water source near the work site to achieve the effect of spraying while working.

[0085] In this embodiment, the walking unit is provided with a clearance space, and a large vehicle can be placed in the clearance space for loading, etc., and thus, unlike other gate-shaped chiseling machines that are directly placed on the top of the prefabricated component, the chiseling machine of this technical solution is carried by a large vehicle and is not affected by the upper end surface of the prefabricated component (the upper end surface of some prefabricated components is uneven and even has external ribs). Furthermore, the prefabricated components on the same production line do not need to be replaced by a crane, and the end beam can be moved horizontally by the track on the large vehicle, and the prefabricated components on different production lines can be chiseled without the need for a crane.

[0086] In this embodiment, a large vehicle can be placed in the clearance space 100 without being affected by the upper end surface of the prefabricated component (the upper end surface of some prefabricated components is uneven and even has external ribs), so the usable space is relatively large, which expands the scope of application.

[0087] Furthermore, a telescopic channel steel and a reinforcing iron plate 12 are also provided on the walking unit 20. At this time, the telescopic channel steel is mainly used as a support seat for the haircutting machine, so that the haircutting machine can move up and down in the haircutting track and play a role in left and right positioning. Because the haircutting machine has a large vibration amplitude during operation and needs to control the distance from the end face of the hollow plate, the reinforcing iron plate 12 provided on the side of the walking unit 20 is used to reinforce the haircutting machine track, reduce the stress it bears in the left and right directions, and improve the restraint force on the haircutting machine and the telescopic channel steel.

[0088] An angle adjustment unit 30, the hair cutting machine 10 is rotatably arranged on the walking unit 20 through the angle adjustment unit 30, and the angle between the hair cutting machine 10 and the walking unit 20 is controlled by the angle adjustment unit 30;

[0089] The spray unit 40 is arranged on the haircutting machine 10. The spray unit 40 is connected to a water source through a spring tube. When the haircutting machine 10 is working, the spray unit 40 is connected to the water source to achieve dust removal during haircutting.

[0090] Refer to the attached Figure 1 As shown, it also includes a telescopic shaft 50, on which a first driving unit 51 is fixed. The first driving unit 51 is used to drive the haircutting machine 10 to rise and fall along the walking unit 20 in the Y-axis direction.

[0091] In this embodiment, a telescopic shaft is added, and then the telescopic shaft is extended and retracted to adjust the distance between the haircutting machine and the construction position. When the distance changes, there is no need to disassemble or assemble, and the telescopic shaft is directly lengthened or shortened to push the haircutting machine far away or close to achieve construction. The first driving unit is set here to save more space. In order to achieve multiple simultaneous operations, there are two haircutting machines 10, and the two haircutting machines 10 are respectively set on both sides of the telescopic shaft 50 through the walking unit 20.

[0092] In this embodiment, two symmetrical roughening machines and walking units are provided, so that roughening construction can be carried out at two locations at the same time. At the same time, in conjunction with the telescopic shaft, when the distances between two boards to be roughened are different, the distance between the two roughening machines is adjusted through the telescopic shaft to cooperate with the roughening construction of boards with different distances.

[0093] Specifically, the first driving unit 51 is implemented by a motor, and the motor supplies gas through a gas tank at the bottom, and the gas tank is connected by a second telescopic tube.

[0094] Refer to the attached Figure 1 As shown, the first driving unit 51 is a lifting motor, and the output shafts at both ends of the lifting motor are respectively connected to steel wire ropes 52, which are wound around the telescopic shaft and connected to the haircutting machine. When in use, the driving motor drives the steel wire rope 52 to expand and contract, thereby driving the haircutting machine 10 to rise or fall along the Y axis.

[0095] Specifically, the output shaft is connected to a drum 53 provided on the travel unit 20, and a steel wire rope 52 is provided on the drum 53, and the steel wire rope 52 is connected to the haircutting machine 10. Furthermore, a coupling 17 is added, which enhances the torsion resistance of the transmission shaft by dividing the entire rotating shaft into sections, and is easy to disassemble and repair.

[0096] In this embodiment, a lifting motor is used to tighten and secure the wire rope through the forward and reverse rotation of the motor, thereby achieving control over the lifting of the haircutting machine. One motor can also be used to control two groups of haircutting machines at the same time, which is low cost and high efficiency.

[0097] Specifically, refer to the attached Figure 4-5 As shown, the walking unit 20 is a frame unit, on which a fixed leg 13 and a movable leg 14 that moves along the Y axis relative to the frame unit are fixed, and the movable leg 14 is connected to the telescopic shaft 50 and the haircutting machine 10 respectively.

[0098] In this embodiment, in order to cooperate with the movement of the telescopic shaft, a movable leg is provided, that is, the entire frame unit is relatively stationary. If the distance between the two chiseling machines needs to be shortened, it is only necessary to adjust the telescopic shaft, and then the movable leg cooperates with the telescopic shaft to realize the telescopic movement.

[0099] In this embodiment, the telescopic steel plate 11 constitutes a movable leg 14, and a fixed leg 13 is arranged above the movable leg 14. In actual use, the corresponding position is adjusted by the telescopic steel plate 11. Specifically, the end of the steel wire 52 is connected to the movable leg 14, and when the telescopic shaft 50 is tightened or extended, the steel wire 52 shortens or extends. At this time, the fixed leg 13 is fixed, and the steel wire 52 approaches or moves away from the drum 53, driving the movable leg 14 to approach or move away from the drum, and then the movable leg 14 is connected to the fixed haircutting machine to approach or move away from the drum 53, realizing its movement on the Y axis.

[0100] In this embodiment, the movement in the Y-axis direction can also be controlled manually, as follows:

[0101] See attached Figure 6 As shown, a haircutting machine 10 is provided on the walking unit 20, and a crank 54 is provided on the inner side of the walking unit 20. The crank 54 is connected with an upper sprocket 55 and a lower sprocket 56 that penetrate through the walking unit 20. The coupling 17 penetrates the walking unit 20 and the roller 53 in the walking unit 20. The crank 54 drives the sprocket to rotate, and then drives the roller 53 to rotate, thereby lifting the movable leg 14 to realize the entire rise.

[0102] Furthermore, the width of the roughening area of ​​the hollow plate produced can be set in the range of 300mm-1000mm, and the roughening area of ​​the 7-head roughening machine is 240mm. After completing the roughening of an area, the height needs to be adjusted, so the roughening trolley needs to have a mechanism that can adjust the height of the roughening machine.

[0103] The main core structure of the height adjustment mechanism of the chiseling machine is the height adjustment screw. The turntable drives the lower sprocket, which drives the upper sprocket through the chain, drives the bevel gear, and finally drives the height adjustment screw to adjust the height. The maximum width of the hollow plate chiseling in our factory is 1000mm, the chiseling machine needs to move 760mm, and the maximum drop between the hollow plate base and the ash truck track is 70mm.

[0104] After calculation, the two 10# channel steels lifted together with the haircutting machine on one side are about 0.9m each, totaling 18kg, the total weight of the outer iron plate is about 9kg, the total weight of the four running wheels is about 10kg, plus the weight of the haircutting machine is 90kg, the lifting weight is about 130kg, and the total weight on both sides is 260kg. The upper sprocket is Φ150, the lower sprocket is Φ30, the medium and large sprocket is Φ150, and the small and medium sprockets are Φ30, so the transmission ratio is , then the force required by the worker is about 96N, and it takes 96N of force to adjust the hair cutting machine. The handle needs to be turned 29 times to adjust the haircutting machine once.

[0105] Example 4

[0106] In this embodiment, the motion realization of the Z axis and the X axis is mainly introduced.

[0107] First, there is movement along the Z axis.

[0108] See attached Figure 2 As shown, it also includes a first track 1, and the chiseling machine 10 realizes the Z-axis movement through the first track 1.

[0109] In this embodiment, in order to realize the roughening construction of the Z axis, a first track 1 is laid, and then its movement is realized through the first track. Specifically, the existing construction equipment can be arranged to move along the first track, such as a ash truck equipment, and the roughening equipment is mounted on the ash truck, and the movement of the ash truck is used to realize the control of the movement.

[0110] Specifically, there are several first rails 1 , and the bottoms of the several first rails 1 are connected and supported by connecting steel plates 2 .

[0111] Further, see Attachment Figure 2 As shown, it also includes a main beam 8, the walking unit 20 is fixedly connected to the main beam 8, and end beams 5 are respectively provided at both ends of the main beam 8. The end beams 5 move along the first track 1 to drive the haircutting machine 10 to realize Z-axis movement.

[0112] Furthermore, a load-bearing steel beam 4 is provided between the end beam 5 and the first track 1, which, on the one hand, enables movement in all directions for connection, and on the other hand, can ensure the connection of the bottom chiseling machine 10. At this time, the ash truck is carried on the first track, and the main beam at the end of the ash truck can drive the entire walking unit 20 to move forward and backward through the movement of the ash truck, thereby realizing the movement of the Z axis.

[0113] In this embodiment, the control of the Z-axis direction is divided from the Y-axis through the end beam, and each has a corresponding support unit, so that the movements are independent of each other and the movement modes do not interfere with each other, thereby improving efficiency.

[0114] Second, there is the movement along the X axis.

[0115] Further, see Attachment Figure 7-8 As shown, the main beam 8 is a trough structure, and a second driving unit for driving the movable leg 14 to move in the X-axis is arranged in the trough structure.

[0116] Specifically, the groove structure is a dovetail groove structure. The dovetail groove is a mechanical structure with a groove shape of ∠. Its function is usually to make mechanical relative motion with high motion accuracy and stability. The dovetail groove is often used in conjunction with a trapezoidal guide rail to play a guiding and supporting role. It is often used on the slide of a machine tool.

[0117] In this embodiment, the movement of the movable legs has two functions: one is to adjust the distance between the two chiseling machines, which is equivalent to adjusting the X-axis displacement; the other is to enable the chiseling machine to chisel in the X direction along the X-axis direction, killing two birds with one stone.

[0118] Further, in order to ensure the relative transmission of the X-axis, refer to the attached Figure 1-3 As shown, a transmission rack 21 is provided in the trough structure, a gear 19 matching the transmission rack 21 is provided on the transmission rack 21, a trolley 6 is provided in front of the gear 19, and the trolley 6 drives the movable leg 14 to move along the X-axis. Specifically, the trolley moves along the third track to realize the movement of the X-axis, and the third track at this time is perpendicular to the first track.

[0119] In this embodiment, a gap is opened at the bottom of the trough body by utilizing the mutual cooperation of the gear rack, and then the trolley is connected to the movable leg along the gap. When the transmission rack and the gear move, the trolley is pushed, driving the movable leg and the haircutting machine on the movable leg to move.

[0120] In order to prevent the movable leg 14 from being unable to move continuously after reaching the highest point, a leg motor is also included. The leg motor is arranged under the track and is used to drive the gear 19 to move continuously, thereby achieving continuous roughening of the X-axis.

[0121] Specifically, refer to the attached Figure 7-8 As shown, based on Example 2, specifically, a crank 54, an upper sprocket 55 and a lower sprocket 56 are provided on the side, and a rack structure meshing with the gear 19 is provided on the upper sprocket 55 or the roller 53, and then when the upper sprocket 55 or the roller 53 rotates, the gear 19 is driven to rotate, so that the entire walking unit moves along the transmission rack 21. If a symmetrical walking unit is set at this time, the two haircutting machines 10 are close to or away from each other, realizing their movement along the X-axis direction. Furthermore, a brake rack 22 is also provided to realize the braking of the haircutting machine 10 when it moves along the X-axis direction.

[0122] In this embodiment, due to the use of a telescopic shaft, when the drum drives the movable leg to move upward, causing the walking unit to move in the X-axis direction, the telescopic shaft is shortened to match the change in length of the wire rope in the horizontal X-axis direction.

[0123] Specifically, the width of the hollow slab to be roughened is between 830mm and 1250mm, and the roughening machine needs to be adjusted between 800mm and 1250mm. When one leg is fixed, the other leg needs to move at least 450mm. Considering the length of the track slider and the travel of the roughening machine when it is fully released, the single-side track needs to be designed to be at least 700mm long and 850mm long. Figure 7-8As shown, the width of the haircutting machine is adjusted by gears and racks. The operating system is moved to the bottom by chain drive. The haircutting width can be adjusted by turning the handle to drive the lower sprocket, the upper sprocket, and finally the coaxial gear. At the same time, the slider is fixed by the rack. The slider is usually locked under the action of the counterweight. When it needs to be moved, the handle can be lifted and the adjustment handle can be turned to adjust it. There is a 10# channel steel between the rack and the dovetail groove, which is used to bear the entire weight of the haircutting machine and the legs.

[0124] Finally, this embodiment describes how to perform angle adjustment.

[0125] Refer to the attached Figure 5 As shown, the angle adjustment unit 30 includes a screw, and both ends of the haircutting machine 10 are rotatably connected to the walking unit 20 through a rotating shaft. The screw 31 is fixed to the haircutting machine 10. When external force acts on the screw 31, the haircutting machine 10 rotates along the rotating shaft on the walking unit.

[0126] In this embodiment, a screw is used. When an external force acts on the screw, the hair cutting machine rotates, thereby adjusting the angle and achieving hair cutting at different angles, thereby expanding the application range of the entire hair cutting machine equipment.

[0127] Specifically, refer to the attached Figure 9-10 As shown, it provides a working schematic diagram of the angle adjustment unit 30;

[0128] Furthermore, the angle adjustment unit 30 includes a rotating shaft 32, and the haircutting machine 10 is fixed in the channel steel on the walking unit 20. At the same time, a stopper 33 and a rubber pad 34 are set in the channel steel, and then the haircutting machine 10 rotates in the channel steel along the rotating shaft to achieve angle adjustment of the haircutting machine.

[0129] After the rotating shaft 32 is connected to the 10# channel steel (i.e., the walking unit), the chiseling machine can be pressed on the surface of the hollow plate to be chiseled by tightening the movable legs on the chiseling machine to achieve self-adjustment. The chiseling machine can adjust the angle by ±15°. The iron plate with rubber pads on the upper surface is used to restrict the backward range of the chiseling machine, and the iron plate with rubber pads on the lower surface is used to prevent the chiseling machine from tilting forward.

[0130] Example 5

[0131] In this embodiment, the description is mainly made in conjunction with the product.

[0132] Specifically, in this embodiment, there is mainly provided an automatic chiseling machine which can be carried on a ash transport vehicle, operated by one person, uses an electric motor to adjust the height, width and narrowness of the chiseling machine, can adjust the chiseling angle, and is accompanied by water mist spraying during operation to reduce dust pollution.

[0133] The principles in this embodiment are:

[0134] The main beam 8 of the haircutting machine 10 is fixed on two walking end beams, and the walking end beams can make the equipment move freely left and right on the track of the ash transport vehicle. One end of the main beam 8 is a fixed arm, and the fixed arm can adjust the up and down of the haircutting machine through a sprocket, and the other end is a movable arm, and the track of the movable leg is connected to the main beam, that is to say, the movable leg is movable on the main beam. Not only can the haircutting machine be adjusted up and down, but also the left and right of the haircutting machine can be adjusted by the motor and the slide rail to control the haircutting distance between the two haircutting machines. The shell of the haircutting machine can rotate freely with the haircutting machine within a certain angle, so as to adjust the angle of the haircutting machine to adapt to the hollow plate arms of different angles. In addition, a spray system is installed above the haircutting machine to spray water mist while working to reduce the harm of dust to the environment and operators.

[0135] The core solution in this embodiment is:

[0136] This is an automatic haircutting device, comprising a haircutting machine angle adjustment mechanism, a height adjustment structure, a width adjustment mechanism, a walking mechanism, and a spraying system. In this embodiment, a walking end beam is included, which can be translated on the ash transport vehicle.

[0137] The advantages of adopting the above structure are:

[0138] 1. All actions of the roughening equipment can be controlled by remote control. In theory, only one person is needed to complete the roughening work of prefabricated components.

[0139] Specifically, the control of multiple directions is integrated into a remote controller, and the up and down, front and back, left and right movements of the entire haircutting machine can be controlled by pressing buttons.

[0140] 2. The roughening equipment is carried by a ash transport vehicle. Compared with most roughening vehicles on the market that run on prefabricated components, this product is not affected by the external extension bars on the upper part of the prefabricated components. When it is necessary to cross the line horizontally or replace the prefabricated components longitudinally, no lifting equipment is required.

[0141] Specifically, the motion trajectory of the ash truck forms the motion trajectory of the track, thereby facilitating the Z-axis motion thereof.

[0142] 3. The roughening machine has an angle adjustment function. The roughening angle can be adjusted by the screw, and the non-vertical sides of the prefabricated components can also be roughened.

[0143] Furthermore, compared with other technologies, the screw adjustment technology requires a certain amount of manual adjustment, but it is low-cost and more applicable to the special structure of the chiseling machine, and can achieve chiseling in an inclined position when chiseling the X-axis.

[0144] 4. Equipped with a spray system, it can reduce dust generated during the chiseling process and protect the working environment and the health of operators.

[0145] Furthermore, by adopting a spiral pipeline, on the one hand, the spray system can be far away from the water source to achieve spray dust removal at a remote location. At the same time, the spray system is arranged above the haircutting machine, so that water can be sprayed from top to bottom to remove dust.

[0146] 5. Each roughening machine can extend a longer rubber wheel to make the roughening head leave the surface of the prefabricated component, thus achieving single-sided roughening.

[0147] In use:

[0148] 1. All the actions of the chiseling equipment including the ash transporter are controlled by a remote control. Theoretically, only one person is needed to operate it, and the operation is labor-saving.

[0149] 2. It is carried by a ash truck and is not affected by the extended reinforcement on the top of the prefabricated component. No lifting equipment is required to replace the prefabricated component.

[0150] 3. It has its own spraying device, which can be used to spray to reduce dust during work.

[0151] 4. The chiseling machine can adjust the angle to adapt to the sides of prefabricated components at different angles.

[0152] 5. A retractable air / water path consisting of a hard tube is realized.

[0153] In the present invention, the transformation of the chiseling machine wheel is also carried out, which is specifically as follows:

[0154] The original chiseling machine had only one wheel and poor stability, so four wheels needed to be welded on the outer shell to enhance its stability and enable the chiseling head to better fit the surface of the component. The wheelbase of the two wheels on one side is 240mm to prevent the chiseling machine from becoming unbalanced when the wheels are outside the beam when the chiseling machine moves to the edge of the beam.

[0155] In this embodiment, after the above solution principle is adopted, the following problems still exist:

[0156] 1) After the up and down control of the hair cutting machine is driven by a sprocket or roller, due to the heavy weight of the hair cutting machine (a single weight is 75KG), the chain and roller speed are relatively large, resulting in the hair cutting machine rising slowly, affecting the hair cutting efficiency.

[0157] 2) The stability of long-distance mechanical transmission is poor, and the continuous use of the chiseling equipment cannot be guaranteed. The operator's energy and physical strength are limited, and the intensity of long-term work is still high.

[0158] 4) The rigidity of 14# channel steel is still insufficient, and the chiseling machine moves in the track with large friction, which affects the up and down movement of the chiseling machine.

[0159] In view of the above three problems, the roughening scheme in this embodiment is improved again:

[0160] 1) Abandoning the manual mechanical transmission, changing to electrical-mechanical transmission, and adopting remote control. That is, fully automatic electrical control, remote control is enough.

[0161] 2) The up and down control of the hair cutting machine changes the original sprocket transmission to a motor-reduction box-wire rope drum system to control the up and down of the hair cutting machine, and the braking is completed by the self-locking function of the reduction box.

[0162] 3) The width control of the chiseling equipment legs changes the original sprocket drive to motor-reduction box-gear control, cancels the original rack brake system, and the self-locking function of the reduction box acts as a brake.

[0163] 4) The second track formed by 14# channel steel is replaced by the 140-type forklift rail with higher rigidity. It has higher rigidity, better verticality, and is not easy to deform. Positioning wheels are added to the trolley to reduce the resistance caused by the friction between the telescopic section and the track.

[0164] During the test, it was found that the longer gas path led to an increase in the weight of the gas pipe, and the longer gas pipe would increase the frequency of interference and collision with other parts on the site. Therefore, after research, the gas path was re-laid on the on-site pedestal. An air port was added every 30 meters, and the gas path and the gas pipe were connected with a quick connector.

[0165] The air pipe uses a lightweight 3mm thick air pipe to reduce weight.

[0166] Chiseling equipment pipeline design:

[0167] In order to realize air supply, air circuit gate valves are installed at both ends of the chiseling machines, and the chiseling machines on both sides can be opened and closed freely, so that the equipment has the function of single-sided chiseling. Because the air circuit needs to be extended and the air pressure is relatively high, the extension amount is up to 1m. Generally, the high-pressure hose has low flexibility, and it is difficult to control its direction when it is retracted. It is easy to interfere with other equipment, and it is easy to fatigue and damage after multiple bends.

[0168] The cylinder-type telescopic pipeline solves the problems of difficult control of the direction of general high-pressure gas pipes and easy interference with equipment. It has a long service life and can achieve the purpose of use.

[0169] Since the pressure and flow of the sprinkler water circuit are low, after discussion, a spring telescopic water pipe was selected.

[0170] It is wrapped in a PVC shell on the outside to ensure that it will not interfere with other equipment during the extension and retraction process.

[0171] 1. Trial operation:

[0172] In March 21, the chiseling equipment was put into trial operation, and the following problems were found during use:

[0173] 1. The wall thickness of the air pipe is too thin, which is easy to bend when bent, resulting in poor air supply. In addition, the site components are complex and the service life is short (easy to wear)

[0174] 2. Close the main valve of the gas circuit. After the chiseling machine stops working, the air pressure in the pipeline is still high, and there are certain safety hazards in removing the air pipe.

[0175] 3. After the electrification transformation, the roughening equipment contains electrical components, and rain protection measures need to be taken.

[0176] 4. The roughening equipment is inconvenient to lift and requires the installation of lifting points.

[0177] 5. When roughening on one side, the metal positioning wheel can easily scratch the surface of the component, affecting its appearance.

[0178] At the same time, after discussion among the team members, the following issues were also discovered:

[0179] 1. There is a lack of anti-car-top-impact and safety protection facilities.

[0180] 2. The spraying effect is not ideal.

[0181] 3. The hose from the spray pipe to the water faucet can be easily hooked and broken by the movable mechanism of the roughening equipment, and its service life is short.

[0182] 2. Improvements after operation:

[0183] In response to the above problems, the design team made the following modifications to the equipment:

[0184] 1. The wall thickness of the total air supply hose is increased to 5.5mm, which not only prolongs its service life but also controls its weight and is not easy to bend and cause poor air supply.

[0185] 2. A pressure relief valve is installed on the main air line of the hair cutting machine. After the work is completed, the air supply is stopped and the pressure relief valve is opened to exhaust the residual compressed air in the equipment.

[0186] 3. A rainproof roof is installed on the chiseling machine to protect the electrical components.

[0187] 4. Lifting lugs are installed on the walking end beam to facilitate lifting.

[0188] 5. A retractable rubber positioning wheel is installed on the shell of the chiseling machine. When chiseling on one side, the rubber positioning wheel extends to prevent the metal positioning wheel from touching the surface of the component.

[0189] 6. The left and right movable legs are equipped with left and right limiters, the upper and lower movable trolleys are equipped with upper and lower limiters, and blocks are installed at the ends of the upper and lower translation tracks to prevent the trolley from falling due to the breakage of the wire rope. Anti-collision rubber blocks are installed at both ends of the walking end beams.

[0190] 7. The spray nozzle has been replaced, and the atomization dust reduction effect is better.

[0191] Replace the sprinkler hose with a stainless steel corrugated water hose that can be bent and shaped freely and, after adjustment, will not come into contact with moving parts.

[0192] 3. Final use effect:

[0193] The improved roughening equipment has been put into normal use. After timing, it takes 8 minutes to chisel a beam, while the original manual roughening took 4 hours, which greatly improves work efficiency. In order to expand the scope of application, our department has also laid air and water lines in the 2# production area, so that the 1# and 2# production areas can use automatic roughening equipment for roughening.
