Description

Technical Field

[0001] This utility model relates to the field of building drilling machinery technology, and in particular to a liftable high-altitude electric hammer support. Background Technology

[0002] A hammer drill is a power tool primarily used for drilling, grooving, and breaking materials such as concrete, brick, and stone. A height-adjustable hammer drill stand is an auxiliary device specifically designed for high-altitude drilling operations. Through a lifting mechanism and stable support structure, it allows the hammer drill to operate at different heights, thereby improving work efficiency and safety. The height-adjustable hammer drill stand is used to quickly adjust the hammer's position according to different working height requirements.

[0003] A search revealed Chinese Patent Publication No. CN213828831U, which discloses an electric hammer support bracket. The bracket includes a main body and a lifting mechanism. The lifting mechanism comprises a first sleeve, a first telescopic tube, and a drive assembly. The drive assembly includes a first pull rope, a first winding wheel, and a steering wheel. Rotating the first winding wheel causes the first telescopic tube to move up and down within the first sleeve. A limit mechanism is provided on the first winding wheel, comprising a limit gear and a limit post. This lifting mechanism controls the raising and lowering of the electric hammer support bracket, fixing the electric hammer to the bracket body. The lifting mechanism then controls the drilling operation, achieving precise control of the drilling process.

[0004] In the aforementioned utility model, the electric hammer bracket is an integrated design. If a component of the integrated bracket is damaged, the repair may require disassembling the entire bracket, which is a complex and costly process, and is also inconvenient for transportation and storage. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a liftable high-altitude electric hammer support, which aims to improve the integrated design of the electric hammer support. Once a component of the integrated support is damaged, the repair may require disassembling the entire support, which is complicated and costly, and also inconvenient for transportation and storage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A liftable aerial work hammer bracket includes a support base one, a support base two disposed on the upper surface of the support base one, a pull plate slidably connected inside the support base one, a pull block fixedly connected to the outer wall of the pull plate, the outer wall of the pull block slidably connected inside the support base one, one end of a support column slidably connected inside the pull block, a spring slidably connected to the outer wall of the support column, one end of the spring fixedly connected to the lower surface of the pull block, the other ends of the support column and the spring both fixedly connected inside the support base one, a first rotating shaft rotatably connected inside the pull block, a rotating rod fixedly connected to the outer wall of the first rotating shaft, the outer wall of the rotating rod rotatably connected inside the support base one and the support base two, a second rotating shaft rotatably connected inside the rotating rod, a locking block fixedly connected to the outer wall of the second rotating shaft, the outer wall of the locking block slidably connected inside the support base two, and a lifting assembly disposed inside the support base two.

[0009] The connection between support one and support two allows for quick use of the electric hammer bracket. Pulling the pull plate causes the pull block to slide. The support column provides limiting support for the pull block, ensuring stable sliding. The sliding of the pull block also compresses the spring. The pull block supports the first rotating shaft, causing the rotating rod to rotate through the first rotating shaft, which in turn causes the locking block to slide through the second rotating shaft. By engaging or disengaging the locking block from support two, support one and support two can be fixed or disassembled.

[0010] As a further description of the above technical solution:

[0011] The lifting assembly includes a rocker arm, the outer wall of which is rotatably connected to the interior of a second support. A first bevel gear is fixedly connected to the outer wall of the rocker arm, and the outer wall of the first bevel gear is rotatably connected to the interior of the second support.

A threaded rod is fixedly connected to the interior of the second bevel gear, and the outer wall of the threaded rod is rotatably connected to the interior of the second support. A telescopic column is threadedly connected to the outer wall of the threaded rod, and the outer wall of the telescopic column is slidably connected to the interior of the second support. An insert block is fixedly connected to the lower surface of the second support, and the outer wall of the insert block is slidably connected to the interior of a first support. A sliding seat is fixedly connected to the lower surface of the first support.

[0012] Through the above technical solution:

[0013] The rocker arm's fixing action on the first bevel gear allows it to rotate simultaneously with the rocker arm's rotation. The meshing action between the first and second bevel gears allows the second bevel gear to rotate synchronously. The fixing action of the second bevel gear on the threaded rod allows the threaded rod to rotate synchronously with the rotation of the second bevel gear. The threaded action between the threaded rod and the telescopic column allows the telescopic column to slide synchronously inside the second support. The fixing action of the second support on the insert block limits the position of the insert block on both the first and second supports, making the docking of the first and second supports more stable.

[0014] As a further description of the above technical solution:

[0015] A support frame is fixedly connected to the upper surface of the telescopic column, and a rotating block is rotatably connected inside the support frame.

[0016] Through the above technical solution:

[0017] The telescopic column serves to fix the support frame, allowing the support frame to slide synchronously with the telescopic column. The support frame also supports the rotating block, enabling the rotating block to rotate stably.

[0018] As a further description of the above technical solution:

[0019] The rotating block is fixedly connected to a threaded column inside, and the outer wall of the threaded column is rotatably connected to the inside of the support frame.

[0027] The support frame is rotatably connected to a first fixed shaft, the outer wall of the first fixed shaft is fixedly connected to a first connecting rod, and the inner side of the first connecting rod is rotatably connected to a second fixed shaft.

[0028] Through the above technical solution:

[0029] The support frame provides support for the first fixed shaft, enabling the first connecting rod to rotate stably. The first connecting rod, by fixing the second fixed shaft, allows the second fixed shaft to rotate.

[0030] As a further description of the above technical solution:

[0031] A second connecting rod is fixedly connected to the outer wall of the second fixed shaft, and the inside of the second connecting rod is fixedly connected to the outer wall of the third fixed shaft.

[0032] Through the above technical solution:

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides a liftable high-altitude work electric hammer support, including a support 1, a support 2 on the upper surface of the support 1, a pull plate 3 slidably connected inside the support 1, a pull block 4 fixedly connected to the outer wall of the pull plate 3, the outer wall of the pull block 4 slidably connected to the inside of the support 1, one end of a support column 5 slidably connected inside the pull block 4, a spring 6 slidably connected to the outer wall of the support column 5, one end of the spring 6 fixedly connected to the lower surface of the pull block 4, the other ends of the support column 5 and the spring 6 both fixedly connected to the inside of the support 1, a first rotating shaft 7 rotatably connected inside the pull block 4, a rotating rod 8 fixedly connected to the outer wall of the first rotating shaft 7, the outer wall of the rotating rod 8 rotatably connected to the inside of the support 1 and the support 2, a second rotating shaft 9 rotatably connected inside the rotating rod 8, a locking block 10 fixedly connected to the outer wall of the second rotating shaft 9, the outer wall of the locking block 10 slidably connected to the inside of the support 2, and a lifting assembly 12 is provided inside the support 2.

[0050] Specifically, the electric hammer bracket can be assembled and used by splicing support 1 and support 2. Support 1 supports the pull plate 3, and the pull plate 3 fixes the pull block 4. Pulling the pull plate 3 allows the pull block 4 to slide inside support 1. The support column 5 is fixed inside support 1 and limits the sliding of the pull block 4. The spring 6 is set between the pull block 4 and support 1 and will be squeezed due to the sliding of the pull block 4. The first rotating shaft 7 connects the pull block 4 and the rotating rod 8, allowing the rotating rod 8 to rotate through the sliding of the first rotating shaft 7. The second rotating shaft 9 connects the rotating rod 8 and the locking block 10, allowing the locking block 10 to slide. When the locking block 10 is retracted, support 1 and support 2 can be spliced ​​and aligned. Releasing the pull on the pull block 4 allows the spring 6 to push the pull block 4 to slide in the opposite direction, thereby locking the locking block 10 into support 2, limiting and fixing support 1 and support 2.

[0051] Reference Figure 1 , Figure 3 and Figure 4 The lifting assembly 12 includes a rocker arm 1201. The outer wall of the rocker arm 1201 is rotatably connected to the inside of the second support 2. A first bevel gear 1202 is fixedly connected to the outer wall of the rocker arm 1201. The outer wall of the first bevel gear 1202 is rotatably connected to the inside of the second support 2. A second bevel gear 1203 is meshed with the tooth end of the first bevel gear 1202. The outer wall of the second bevel gear 1203 is rotatably connected to the inside of the second support 2. A threaded rod 1204 is fixedly connected to the inside of the second bevel gear 1203. The outer wall of the threaded rod 1204 is rotatably connected to the inside of the second support 2. A telescopic column 1205 is threadedly connected to the outer wall of the threaded rod 1204. The outer wall of the telescopic column 1205 is slidably connected to the inside of the second support 2. An insert block 11 is fixedly connected to the lower surface of the second support 2. The outer wall of the insert block 11 is slidably connected to the inside of the first support 1. A sliding seat 13 is fixedly connected to the lower surface of the first support 1.

[0052] Specifically, support 2 supports rocker arm 1201, and rocker arm 1201 fixes first bevel gear 1202. By rotating rocker arm 1201, first bevel gear 1202 can rotate stably inside support 2. First bevel gear 1202 meshes with second bevel gear 1203. First bevel gear 1202 fixes threaded rod 1204, so threaded rod 1204 rotates synchronously with second bevel gear 1203. Threaded rod 1204 is threaded together, allowing threaded rod 1204 to slide against the inner wall of support 2. The height of the electric hammer can be flexibly adjusted by adjusting the height of threaded rod 1204. Support 2 fixes insert block 11. When insert block 11 is inserted into support 1, it limits the position of support 1 and support 2. Sliding seat 13 fixes support 1. The universal wheel on sliding seat 13 can flexibly adjust the position of electric hammer.

[0053] Reference Figure 1 , Figure 2 and Figure 5 A support frame 17 is fixedly connected to the upper surface of the telescopic column 1205. A rotating block 18 is rotatably connected inside the support frame 17. A threaded column 19 is fixedly connected inside the rotating block 18. The outer wall of the threaded column 19 is rotatably connected to the inside of the support frame 17. A threaded block 20 is threadedly connected to the outer wall of the threaded column 19. A third fixed shaft 14 is rotatably connected inside the threaded block 20. A first fixed shaft 21 is rotatably connected inside the support frame 17. A first connecting rod 22 is fixedly connected to the outer wall of the first fixed shaft 21. A second fixed shaft 23 is rotatably connected inside the first connecting rod 22. A second connecting rod 24 is fixedly connected to the outer wall of the second fixed shaft 23. The inner wall of the second connecting rod 24 is fixedly connected to the outer wall of the third fixed shaft 14. A connecting shaft 15 is fixedly connected inside the second connecting rod 24. A clamping block 16 is rotatably connected to the outer wall of the connecting shaft 15.

[0054] Specifically, the support frame 17 is fixed to the upper surface of the telescopic column 1205 to support the rotating block 18. The rotating block 18 fixes the threaded column 19. Rotation of the rotating block 18 allows the threaded column 19 to rotate stably inside the support frame 17. The threaded column 19 and the threaded block 20 are threadedly connected, allowing the threaded block 20 to slide synchronously with the rotation of the threaded column 19. The third fixed shaft 14 connects the threaded block 20 and the second connecting rod 24, allowing the second connecting rod 24 to rotate synchronously through the rotation of the third fixed shaft 14. 23 serves to connect the second connecting rod 24 and the first connecting rod 22. The first fixed shaft 21 rotates inside the support frame 17 to support and fix the first connecting rod 22, thereby making the first connecting rod 22 rotate stably. The connecting shaft 15 serves to connect the second connecting rod 24 and the clamping block 16, allowing the clamping blocks 16 on both sides to slide simultaneously. By adjusting the distance between the clamping blocks 16 on both sides, the electric hammer can be clamped and fixed. Since there are fixed structures on both sides, the electric hammer can be clamped and fixed on both sides, ensuring the stability of the electric hammer during the drilling process.

[0055] Working principle: When the bracket is needed, support 1 and support 2 are spliced ​​together. Pulling the pull plate 3 causes the pull block 4 to slide. The pull block 4 will slide through the support column 5 and compress the spring 6 during the sliding process. When the pull block 4 slides, it will drive the rotating rod 8 to rotate through the first rotating shaft 7. When the rotating rod 8 rotates, it will pull the locking block 10 to slide through the second rotating shaft 9. At this time, support 1 and support 2 can be aligned. Insert the insertion block 11 into the inside of support 1. Release the pull plate 3. The spring 6 will push the locking block 10 in the opposite direction to lock it into the inside of support 2, thus fixing support 1 and support 2. This achieves the effect of quick assembly and disassembly of support 1 and support 2 in different scenarios, which is convenient for individual maintenance and replacement and convenient for transportation.

[0056] For the hammer drill to be fixed in place, rotating the rotating block 18 causes the threaded column 19 to rotate. When the threaded column 19 rotates, it causes the threaded block 20 to slide. The threaded block 20 then drives the second connecting rod 24 to rotate via the third fixed shaft 14. The second connecting rod 24 then drives the first connecting rod 22 to rotate via the second fixed shaft 23. Simultaneously, the rotation of the second connecting rod 24 causes the connecting shaft 15 and the clamping block 16 to slide, adjusting the distance between the two clamping blocks 16 to clamp and fix the hammer drill on both sides, thus facilitating its fixation and ensuring stability during drilling. The sliding seat 13 can be used to support the hammer drill. The frame can rotate and move in all directions. Rotating the rocker arm 1201 drives the first bevel gear 1202 to rotate, and the second bevel gear 1203 drives the threaded rod 1204 to rotate through the first bevel gear 1202. In turn, the rotation of the threaded rod 1204 drives the telescopic column 1205 to slide, which flexibly adjusts the height of the electric hammer to meet different drilling height requirements. This bracket not only facilitates the quick assembly and disassembly of support 1 and support 2 in different scenarios, but also facilitates individual maintenance and replacement and transportation. It also facilitates the fixing of the electric hammer and ensures the stability during the drilling process.

[0057] 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.
