Description

Technical Field

[0001] This utility model relates to the field of construction machinery accessories technology, and in particular to an automatic drilling dustproof lifting bracket for electric hammers. Background Technology

[0002] In home renovation and construction, electric hammers are frequently used for drilling, especially during ceiling installation or other roof work. Workers often need to use ladders or other supports to reach the required height. During this process, workers constantly hold the electric hammer, which is heavy and makes manual operation very strenuous. Furthermore, the drilling process generates a large amount of dust and debris, creating a harsh working environment where workers are likely to inhale the dust. To address these issues, Chinese Utility Model Patent Publication No. CN206550967U discloses a dustproof telescopic support for electric hammer drilling. This support uses a foot pedal to operate a lever end, which, through leverage, allows the electric hammer to drill. However, this support is not convenient for quickly and accurately locating the drilling position for automatic drilling, resulting in wasted time. Additionally, the lifting mechanism is inconvenient to operate during raising and lowering, thus reducing work efficiency. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides an automatic dustproof lifting bracket for electric hammer drilling, which aims to solve the problems of harsh environment during electric hammer construction, great harm to human body, and the need for the bracket to quickly adjust its height and automatically drill holes as the construction height changes.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic dustproof lifting bracket for electric hammer drilling, comprising an automatic dustproof switch system and a bracket lifting system. The automatic dustproof switch system is connected to the bracket lifting system at its lower part. The automatic dustproof switch system includes an electric hammer sleeve and a dust guide pipe welded to one side of the sleeve. The electric hammer sleeve is used to collect dust and discharge it through the dust guide pipe. A jacking pin is installed at the connection between the dust guide pipe and the electric hammer sleeve using a collar that can move up and down. The collar is welded to the dust guide pipe, and the jacking pin is installed on the collar. When the electric hammer bracket is raised to the drilling position, the jacking pin presses down on the top of the concrete to act as a switch. The jacking pin is equipped with a spring and a switch pin. The spring is fitted into the switch pin and inserted into the jacking pin to act as an automatic clutch. A switch pin plate is installed on the lower side of the switch pin, which controls the electric hammer switch. A sliding electric hammer support is provided on the dust guide pipe, which supports the electric hammer. A support fixing pin is installed on the side of the sliding electric hammer support to facilitate fixing the electric hammer and make it stable during operation.

[0005] The electric hammer sleeve is provided with a dust guide port at the welding point between it and the dust guide pipe, which is used to discharge dust during electric hammer drilling operations.

[0006] The upper part of the electric hammer sleeve is equipped with a rubber dust cover, which is fixedly installed with an inner retaining spring to collect dust. The lower part of the electric hammer sleeve is equipped with a sealing rubber ring to prevent dust from flying away.

[0007] The support lifting system consists of a main support rod, dust guide pipe two, dust guide pipe three, dust guide pipe four, lifting arm one, and lifting arm two. Dust guide pipe four is located at the bottom and can be sequentially fitted into dust guide pipe three and dust guide pipe two. A collar is provided at the bottom of dust guide pipe four, which is connected to the main support rod, allowing dust guide pipe four to move up and down. Dust guide pipe two is welded to the upper part of lifting arm one, and dust guide pipe three is welded to the upper part of lifting arm two. A collar is welded to the lower part of lifting arm two and connected to lifting arm two through the collar. A collar is welded to the lower part of lifting arm two and connected to dust guide pipe four through the collar. Dust guide pipe two and dust guide pipe three are raised and lowered by lifting arm one and lifting arm two. A dust outlet is provided at the lower end of dust guide pipe four for discharging dust collected during construction.

[0008] The dust guide tube is welded to a ratchet bracket. The ratchet bracket is equipped with a ratchet, a ratchet shaft, a crank, and a lifting switch. The crank drives the ratchet to rotate the ratchet shaft, and the lifting switch can control the raising and lowering.

[0009] A movable pulley is installed on the collar connecting the dust guide pipe four and the lifting arm two, and a movable pulley two is welded and installed on the dust guide pipe three.

[0010] The lifting arm is provided with a wire rope fixing hole. After the wire rope is fixed, it passes through the movable pulley one and the movable pulley two and is fixed on the ratchet shaft. Switch the lifting switch on the ratchet bracket to the rising mode. Crank the handle to wind the wire rope around the ratchet shaft. Under the action of pulleys one and two, the lifting arm one rises first, thus raising the dust guide tube two. The dust guide tube two is then pulled out of the dust guide tube three. When the dust guide tube two reaches its maximum height, the lifting arm two, under the action of the wire rope, raises the dust guide tube three, which is then pulled out of the dust guide tube four. Adjust the height according to the construction requirements. After finishing work, switch the lifting switch on the ratchet bracket to the lowering mode. Crank the handle to release the wire rope from the ratchet shaft. Under the action of pulleys one and two, the lifting arm one lowers, thus lowering the dust guide tube two and retracting it into the dust guide tube three. When the dust guide tube two is fully retracted into the dust guide tube three, the lifting arm two, under the action of the wire rope, lowers, raising the dust guide tube three and retracting it into the dust guide tube four.

[0011] The upper part of the dust guide tube is welded with a collar, which is connected to the main support rod, allowing the dust guide tube to move up and down. A pressure handle lever arm is connected to the collar, and the pressure handle lever arm is connected to the pressure handle through a shaft pin. When the electric hammer needs to perform drilling operations, the pressure handle is used to drive the pressure handle lever arm, causing the dust guide tube to move up and down, thus providing power for the electric hammer to perform drilling operations.

[0012] The main support rod is equipped with a handrail to facilitate manual stabilization of the electric hammer drilling bracket during operation, and a bottom corner is provided at the lower end to prevent the electric hammer bracket from slipping.

[0013] The dust guide pipe is equipped with a dust guide hose. In addition to the support lifting system, the dustproof automatic switch system can be used in conjunction with other drilling supports.

[0014] The present invention has the following beneficial effects: In the present invention, the dustproof automatic switch system can quickly locate the drilling position of the electric hammer and quickly and automatically drill continuously. The dust collected during construction will not form dust, which changes the harsh construction environment. The height of the electric hammer support can be conveniently adjusted through the support lifting system, so that the workers can operate it easily and freely during construction without having to adjust the support when changing positions, thus saving time and improving construction efficiency.

[0026] The technical solutions of the embodiments 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.

[0027] like Figure 1 and Figure 2 As shown, the first embodiment of this utility model provides an automatic electric hammer drilling dustproof lifting bracket, which includes an automatic dustproof switch system 1 and a bracket lifting system 2. The lower part of the automatic dustproof switch system 1 is connected to the bracket lifting system 2, forming the main body of this utility model. The automatic dustproof switch system 1 includes an electric hammer sleeve 3 and a dust guide pipe 4 welded to one side of the sleeve. A dust guide port 15 is provided at the welding point between the electric hammer sleeve 3 and the dust guide pipe 4 for discharging dust during electric hammer drilling operations. The electric hammer sleeve is used to collect dust and discharge it through the dust guide pipe 4. At the connection between the dust guide pipe 4 and the electric hammer sleeve 3, a jacking pin 6 is installed, which can move up and down, using a collar 5. The collar is welded to the dust guide pipe, and the jacking pin 6 is installed on the collar. When the electric hammer support is raised to the drilling position, the jacking pin 6 pushes against the top of the concrete, acting as a pressure switch. The jacking pin 6 is equipped with a spring 7 and a switch pin 8. The spring 7 is fitted into the switch pin 8 and inserted into the jacking pin 6, which acts as an automatic clutch. A switch pin plate 9 is installed on the lower side of the switch pin, which controls the electric hammer switch. A sliding electric hammer support 10 is provided on the dust guide pipe 4, which supports the electric hammer. A support fixing pin 11 is installed on the side of the sliding electric hammer support 10 to facilitate fixing the electric hammer and make it stable during operation.

[0028] The upper part of the electric hammer sleeve 3 is provided with a rubber dust cover 12, which is fixedly installed with an inner retaining spring 13 to collect dust. The lower part of the electric hammer sleeve 3 is provided with a sealing rubber ring 14 to prevent dust from flying away.

[0029] like Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 The support lifting system consists of a main support rod 16, a second dust guide pipe 17, a third dust guide pipe 18, a fourth dust guide pipe 19, a first lifting arm 20, and a second lifting arm 21. The fourth dust guide pipe 19 is located at the bottom and can be sequentially fitted with the third dust guide pipe 18 and the second dust guide pipe 17. The lower part of the fourth dust guide pipe 19 is provided with a collar 5, which is connected to the main support rod 16, allowing the fourth dust guide pipe 19 to move up and down. The second dust guide pipe 17 is welded to the upper part of the first lifting arm 20. Dust guide pipe 3 18 is welded to the upper part of lifting arm 2 21. A collar 5 is welded to the lower part of lifting arm 1 20 and connected to lifting arm 2 21 through collar 5. A collar 5 is welded to the lower part of lifting arm 2 21 and connected to dust guide pipe 4 19 through collar 5. Dust guide pipe 2 17 and dust guide pipe 3 18 are raised and lowered by lifting arm 1 20 and lifting arm 2 21. Dust guide pipe 4 19 has a dust outlet 36 at the lower end for discharging dust collected during construction.

[0030] like Figure 2 and Figure 5 As shown, a ratchet bracket 22 is welded and fixed on the dust guide tube 19. The ratchet bracket 22 is equipped with a ratchet 23, a ratchet shaft 24, a crank 25, and a lifting switch 26. The crank 25 drives the ratchet 23 to rotate the ratchet shaft 24, and the lifting switch 26 can control the raising and lowering.

[0031] like Figure 2 A movable pulley 27 is installed on the collar 5 connecting the dust guide pipe 19 and the lifting arm 21, and a movable pulley 28 is installed on the dust guide pipe 18.

[0032] like Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the lifting arm 20 is provided with a wire rope fixing hole 29. After the wire rope 30 is fixed, it passes through the movable pulley 27 and the movable pulley 28 in sequence and is fixed on the ratchet shaft 24. When the lifting switch 26 on the ratchet bracket 22 is switched to the lifting mode, the handle 25 is cranked, causing the wire rope to wind on the ratchet shaft 24. Under the action of the movable pulleys 27 and 28, the lifting arm 20 is first lifted, thereby lifting the dust guide pipe 17. The dust guide pipe 17 is then pulled out from the dust guide pipe 18. When the dust guide pipe 17 reaches its maximum height, under the action of the wire rope, the lifting arm 21 lifts the dust guide pipe 18, which is then pulled out from the dust guide pipe 19. The height is adjusted according to the construction requirements. To adjust the height, after finishing work, switch the lifting switch 26 on the ratchet bracket 22 to the lowering mode. By cranking the handle 25, the wire rope is released from the ratchet shaft. Under the action of the first movable pulley 27 and the second movable pulley 28, the lifting arm 20 descends, thereby driving the dust guide tube 17 to descend and retract into the dust guide tube 3 18. When the dust guide tube 17 is fully retracted into the dust guide tube 3 18, the lifting arm 21 descends under the action of the wire rope. The lifting arm 21 drives the dust guide tube 3 18 to descend and retract into the dust guide tube 4 19.

[0033] like Figure 2 , Figure 4 and Figure 9 As shown, a collar 5 is welded to the upper part of the dust guide tube 19. The collar 5 is connected to the main support rod 16, allowing the dust guide tube 19 to move up and down. A pressure handle arm 31 is connected to the collar 5. The pressure handle arm 31 is connected to the pressure handle 33 through a shaft pin 32. When the electric hammer needs to perform drilling operations, the pressure handle 33 drives the pressure handle arm 31 to move the dust guide tube 19 up and down, thus providing power for the electric hammer to perform drilling operations.

[0034] like Figure 2 As shown, the main support rod 16 is equipped with a handrail 34, which makes it easy to manually stabilize the electric hammer drilling bracket during operation. The lower end is equipped with a bottom corner 37 to prevent the electric hammer bracket from slipping.

[0035] like Figure 3 As shown, in the second embodiment provided by this utility model: the dust guide pipe 4 is provided with a dust guide hose 35. In addition to the bracket lifting system 2, the dustproof automatic switch system 1 can be used in conjunction with other drilling brackets.

[0036] Working principle: When drilling holes in ceilings or high-altitude concrete using an electric hammer, first place the electric hammer on the sliding electric hammer support 10 and fix it with the support pin 11. Secure and lock it in place. Insert the automatic dustproof switch system 1 into the support lifting system 2. Then, place the electric hammer automatic drilling dustproof lifting support vertically. Hold the handrail 34 with your left hand. According to the required working height, switch the lifting switch 26 on the ratchet support 22 to the rising mode. Shake the crank 25 to make the wire rope wind around the ratchet shaft 24. Under the action of the first movable pulley 27 and the second movable pulley 28, the lifting arm 1 20 is first driven to rise, thereby driving the dust guide pipe 2 17 to rise. The dust guide pipe 2 17 is pulled out from the dust guide pipe 3 18. When the dust guide pipe 2 17 rises to the maximum height, under the action of the wire rope, the lifting arm 2 21 drives the dust guide pipe 3 18 to rise, and the dust guide pipe 3 18 is pulled out from the dust guide pipe 4 19. Adjust the height according to the required construction height. If the floor height of an ordinary building is relatively low... When the height is low, the height of the dust guide pipe 2 after it rises is sufficient to meet the construction height requirements. When encountering buildings with higher ceilings, the height can be adjusted according to the site height requirements. When adjusted to the working height, the right hand controls the pressure handle 33 up and down. The pressure handle 33 controls the pressure handle lever 31 to move the dust guide pipe 4 up and down, thereby driving the jacking pin 6 on the dust guide pipe 1. The spring 7 under the jacking pin 6 controls the switch needle 8. The switch needle 8 causes the switch needle plate 9 to press down the electric hammer switch, activating the electric hammer switch, so that the electric hammer can automatically drill holes under the operation of the worker. This utility model prevents the electric hammer from scattering dust when working at heights, creating a good construction environment. It can also quickly and automatically drill holes, improve the worker's work efficiency, and reduce the workload. The support lifting system 2 can be freely adjusted according to the construction height requirements.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
