Description
Technical Field
[0001] The utility model relates to the technical field of equipment for supporting application in building construction, in particular to a device for grooving walls. Background Art
[0002] In building construction and interior decoration, sometimes in order to install pipeline, water pipe, gas pipe, etc., an electric wall grooving machine is used to perform grooving operations on corresponding positions of the wall. The general structure of the existing electric wall grooving machine includes a motor and a grooving cutting blade. During operation, the operator holds the handle of the motor, and the motor drives the cutting blade to rotate to perform grooving operations on the corresponding position of the wall in the horizontal or vertical direction.
[0003] Although the existing electric wall grooving machine meets the grooving work requirements of the wall to a certain extent, due to structural limitations, there are still the following technical problems to be solved urgently. First: Since the operator needs to hold the device throughout the operation, affected by its own gravity and the vibration force during grooving, it will bring inconvenience to the operator after a long time and increase the labor intensity of the operator accordingly. Second: The rotating shaft of the motor only has one cutting blade. When grooving, it is necessary to groove on the upper and lower or left and right sides respectively to meet the requirements (after grooving left and right or up and down, use other tools to pry open the wall between the two grooves, etc.). The above operation mode has relatively low work efficiency and is not conducive to improving work efficiency. If two cutting blades are installed on the rotating shaft of the motor, then due to cutting the wall left and right or up and down simultaneously, the force exerted by the operator's hand on the wall needs to be greater and the vibration force to be overcome is also greater, which will bring more inconvenience to the operator's operation and greater work intensity. In summary, it is particularly necessary to provide a wall grooving device that can bring convenience to the operator and improve work efficiency. Summary of the Utility Model
[0004] In order to overcome the disadvantages of the existing electric wall grooving machine due to structural limitations as described in the background, the utility model provides a device for grooving walls based on the electric wall grooving machine body. Two sets of cutting blades are installed on the rotating shaft of the electric wall grooving machine. The operator does not need to hold the handle of the motor for operation. Through hand pushing and power switch control, grooving operations can be performed on the wall left and right or up and down, thus bringing convenience to the operator and improving work efficiency accordingly.

A fixing rod 8 is respectively horizontally welded to the outside of the bearing sleeves of the front and rear sets of linear bearings; there are two sets of detection mechanisms 5. Each set includes a housing 51 and a power switch ASN. Sheet-shaped rectangular magnets 52 are adhesively bonded to the outside perimeter of the housing 51. The housing of the power switch ASN is adhesively bonded to the upper end inside the housing 51. The two sets of detection mechanisms are respectively attracted to the support plate 4 on both sides of the lower end of the motor housing through the magnets 52; the power switch S1, the power supply module E1, and the prompt circuit 6 are installed on the circuit board inside the component box 9, and the component box 9 is installed outside the middle of the front end of the vehicle body 3.
[0016] Figure 1 、 2, as shown in FIGS. 2 and 3, the rear end of the cutting blade 105 of the electric wall slotting machine body is located at the outer rear sides of the support plate 4 and the vehicle body 3. The power switch ASN is a push-button normally closed micro power switch. The buttons of the power switches ASN of the two sets of detection mechanisms respectively contact both sides of the lower end of the housing of the motor 101, and the internal contacts of the power switch ASN are open. The prompting circuit includes a resistor R1, a triode Q1 and a buzzer B1 connected by circuit board wiring. One end of the resistor R1 is connected to the base of the triode Q1, and the collector of the triode Q1 is connected to the negative power input terminal of the buzzer B1.

[0017] Figure 1 , 2As shown in FIGS. 2 and 3, the present utility model is based on the electric wall slotting machine body 1 and has two cutting blades 105. After turning on the power switch of the electric wall slotting machine body 1, the rotating shaft of the electric wall slotting machine body 1 can drive the cutting blades to rotate, and the two cutting blades 105 can simultaneously perform slotting operations on the wall in the horizontal or vertical direction; specifically, when the staff loosens the nuts 106 fixing the two cutting blades 105 respectively, the distances between the two cutting blades 105 on the rotating shaft can be adjusted respectively. After adjustment, the nuts are fixed, and subsequent relatively wide or relatively narrow slotting operations can be performed on the wall. When the staff loosens the nut 106 of the bolt 102 at the rear end of the motor, the motor can be adjusted up or down to move up or down along the guide groove 71 of the fixing plate 7, or the cutting blade 105 can be adjusted from the horizontal state to the vertical state. After adjustment in place, the nut 106 is tightened. When the cutting blades 105 are horizontally distributed, horizontal slotting operations can be performed on the wall. When the cutting blades 105 are vertically and horizontally distributed, vertical and horizontal slotting operations can be performed on the wall. After the AC 220V power supply enters the power module E1, the DC 24V power supply output from the 3rd and 4th pins of the power module E1 enters the power input terminals of the power switch S1 and the prompting circuit. The staff pushes the vehicle body 3 close to the wall with both hands (the rear ends of the two cutting blades 105 contact the wall), and moving left or right along the front of the wall can perform slotting and cutting operations on the wall (before initial slotting, push the vehicle body backward with both hands so that the two cutting blades 105 can perform slotting on the wall). Before the equipment horizontally cuts the wall, after the staff toggles the handle of the power switch S1 to the left or right, the 1st and 2nd pins and the 3rd and 4th pins or the 5th and 6th pins of the power switch S1 are respectively connected. In this way, the positive and negative or negative and positive two ends of the input terminals of the electric push rod M1 will be powered on. After the positive and negative or negative and positive two ends of the power input terminals of the electric push rod M1 are powered on, its push rod drives the electric wall slotting machine body 1 through the support plate to move up or down through the linear bearing 2, so that horizontal slotting can be conveniently performed on the wall at different heights (turn off the power switch after in place). Before the equipment vertically cuts the wall, after the staff toggles the handle of the power switch S1 to the left or right, the 1st and 2nd pins and the 3rd and 4th pins or the 5th and 6th pins of the power switch S1 are respectively connected. In this way, the positive and negative or negative and positive two ends of the input terminals of the electric push rod M1 will be powered on. After the positive and negative or negative and positive two ends of the power input terminals of the electric push rod M1 are powered on, its push rod drives the electric wall slotting machine body 1 through the support plate to move up or down through the linear bearing 2, so that vertical and horizontal slotting can be conveniently performed on the wall at different heights (turn off the power switch after in place). Through the above, the present new type can perform left - right or up - down slotting operations on the wall through the control of the power switch, which brings convenience to the staff and correspondingly improves the work efficiency; it should be noted that when the present application performs horizontal slotting and vertical slotting, for the wall with a height lower than the lower dead - point position of the electric push rod, no slotting is performed, and generally, the slotting of indoor walls will not be too low, so it does not affect the use and the application prospect of the present application is good.
[0018] Figure 1, 2 As shown in FIGS. 2 and 3, before the horizontal and vertical cutting of the present application, by adjusting the positions of the two sets of detection mechanisms 5 suction-engaged on the support plate, the two sets of detection mechanisms 5 are respectively located on both sides of the motor housing, and the buttons of the power switches ASN respectively contact both sides of the lower end of the motor housing (before the horizontal slotting, the housings of the two sets of detection mechanisms 5 are horizontally suction-engaged and distributed, and the buttons of the two power switches ASN respectively contact both sides of the lower end of the motor housing; before the vertical slotting, the housings of the two sets of detection mechanisms 5 are vertically suction-engaged and distributed, and the buttons of the two power switches ASN respectively contact both sides of the lower end of the motor housing). During operation, when the motor is firmly fixed, its lower end will not move left or right. The buttons of the two power switches ASN contact both sides of the lower end of the motor housing, and the internal contacts of the two power switches ASN are open. In this way, the 12V power supply does not enter the base of the triode Q1, and the buzzer B1 will not be powered on and sound, indicating that the motor has no displacement. When the nut 106 of the fixing bolt 102 becomes loose for various reasons, the lower end of the motor moves left or right. In this case, the right or left side of the lower end of the motor will separate from the button of the power switch ASN at the right or left end, and then the internal contact of one of the corresponding power switches ASN will close. The 12V power supply will enter the base of the triode Q1 through the corresponding power switch ASN and the resistor R1 for current limiting and voltage reduction. The triode Q1 conducts, and the collector outputs a low level and enters the negative power input terminal of the buzzer B1. The buzzer B1 is powered on and sounds to prompt the staff that the motor is loose and needs to be fixed, ensuring the stable and reliable operation of the equipment. The power supply module A1 is a finished product of an AC 220V to DC 24V switching power supply module of model LRS-450-24V, with a power of 3KW (having two power input terminals and two power output terminals); the working voltage of the motor of the electric wall slotting machine body is AC 220V and the power is 3KW; the electric push rod M1 is a finished product of a reciprocating electric telescopic rod with a power of 300W of model BST-YF-LBST-YF-; the resistance value of the resistor R1 is 10K; the triode Q1 is an NPN-type triode of model 9013; the buzzer B1 is a finished product of an active buzzer of model SFM-27DC3-24V.
