Description

Technical Field

[0001] This application relates to the field of construction equipment, and in particular to an electric hammering device for compaction hammers. Background Technology

[0002] A compaction apparatus is a specialized instrument used for foundation filling projects in water conservancy projects such as dams, highways, railways, civil aviation airports, municipal engineering, and civil buildings. It measures the relationship between the moisture content and dry density of soil under standard compaction work, thereby determining the optimum moisture content and corresponding maximum dry density of the soil sample.

[0003] The indoor compaction test procedure is as follows: A sample with a certain moisture content is placed into a compaction mold in two or three layers. Each layer is compacted with a compaction hammer to a certain number of blows. The compaction work done on each layer is the product of the hammer weight, the hammer drop distance, and the number of blows. After the soil layers are compacted to the full volume of the mold, the moisture content and wet density of the compacted soil are measured, and the dry density is calculated. Five or more soil samples with different moisture contents are compacted using the same method, and the moisture content and dry density of each sample can be obtained. These data points are plotted with moisture content as the x-axis and dry density as the y-axis. The curve connecting these points is the curve that reflects the compaction characteristics of the soil, called the compaction curve.

[0004] Regarding the aforementioned technologies, the inventors believe that during the testing process, the compaction hammer needs to be raised and lowered once to compact the material. Often, a single test requires a large number of compactions, making the operation complex and cumbersome for the operator. Summary of the Invention

[0005] To improve the ease of operation for test personnel, facilitate rapid test operation, and enhance overall test efficiency, this application provides an electric hammering device for compaction.

[0006] This application provides an electric compaction hammer device, which adopts the following technical solution:

[0007] An electric compaction hammer device includes a vertically arranged material bucket, with a compaction hammer vertically arranged above the material bucket. The device is characterized by: a first conveyor belt vertically arranged on one side of the material bucket; a second conveyor belt vertically arranged opposite the first conveyor belt on the side of the material bucket away from the first conveyor belt; the second conveyor belt vertically arranged; a clamping structure provided on the first conveyor belt; the clamping structure can clamp the compaction hammer, causing the compaction hammer to rise via the first conveyor belt; the clamping structure includes opposing clamping plates, each clamping plate including an arc-shaped plate; the two opposing arc-shaped plates are hinged at their ends near the first conveyor belt, and the arc-shaped plates and the compaction hammer are opposite each other; a locking block is fixedly connected to the inner side of the arc-shaped plate; a locking groove is formed on the compaction hammer relative to the locking block; when the two arc-shaped plates move towards each other, the locking block extends into the locking groove; an abutment portion is fixedly connected to the end of the arc-shaped plate near the first conveyor belt; and the two opposing abutment portions are connected between each other. A horizontally arranged elastic element is provided. A support part is fixedly connected to the side of the arc-shaped plate away from the abutment part. An opening structure is provided on the upper part of the second conveyor belt relative to the clamping structure. The opening structure includes a vertically arranged support rod on the upper part of the second conveyor belt near the material bucket. An opening plate is sleeved on the top of the support rod. Second inclined walls are opened on both sides of the opening plate along the width direction. The second inclined walls are gradually inclined towards the relatively close side along the height direction from top to bottom. The bottom end of the opening plate along the width direction is the same as the gap between the two opposing support parts. The opening structure can disengage the compaction hammer from the clamping structure. A preparation plate is provided on the lower part of the side of the first conveyor belt near the material bucket. Two preparation plates are arranged opposite each other. A first inclined wall is opened on the side of the two preparation plates near the abutment part. The two first inclined walls are gradually inclined towards the relatively opposite side along the height direction from top to bottom. The distance between the inner walls of the bottom ends of the two first inclined walls is the same as the distance between the outer walls of the two opposing abutment parts.

[0008] By adopting the above technical solution, the clamping structure moves upward along the side of the first conveyor belt closest to the material bucket, clamping the hammer and causing it to move upward. When the hammer reaches the position of the opening structure, the opening structure opens the clamping structure, causing the clamping structure and the hammer to disengage, allowing the hammer to fall. The first conveyor belt continues to move the clamping structure, achieving cyclical operation. This improves the ease of operation for test personnel, facilitates rapid test operation, and increases overall test efficiency. Furthermore, by inserting the locking block on the arc-shaped plate into the slot, the arc-shaped plate moves towards the relatively closer side. Thus, the clamping block drives the hammer to move upward, and after the clamping plate moves to the position of the opening structure, the opening structure disengages the clamping block inside the slot, causing the hammer to fall. Through the sliding contact between the abutment part and the preparation plate, the preparation plate guides the abutment part to move towards the relatively closer side, thereby driving the arc-shaped part to move towards the relatively opposite direction, opening the clamping plate, thus facilitating the clamping and fixing of the hammer. When the clamping plate moves upward with the first conveyor belt, the clamping plate and the opening plate come into contact with each other. Guided by the second inclined wall, the side of the clamping plate closest to the second inclined wall moves towards the relatively opposite direction, thus opening the clamping plate.

[0009] Optionally, a base plate is horizontally arranged on the second conveyor belt relative to the clamping structure. Two base plates are arranged opposite each other and are slidably connected to the second conveyor belt. The upper surface of the base plate and the lower surface of the support are opposite each other. A top plate is also arranged above the base plate. Two top plates are arranged opposite each other and are slidably connected to the second conveyor belt. A space is left between the top plate and the base plate for placing the clamping structure. A lower guide plate is vertically arranged on the side of the second conveyor belt near the material bucket. Two lower guide plates are arranged opposite each other, and the sidewalls of the two lower guide plates that are close to each other gradually move towards each other along the height direction from bottom to top. The two bottom guide plates are tilted towards each other, with openings at their top ends. The size of these openings is the same as the width of the two bottom plates when they come into contact. This allows the two bottom plates to slide out from the top ends of the bottom guide plates and slide between the two opposing bottom guide plates. When the bottom plates are at the bottom of the second conveyor belt, they are in a relatively separated state. At this time, the support part of the clamping plate can enter between the bottom plate and the top plate from the gap between the two opposing bottom plates. As the bottom plates move with the second conveyor belt, they are guided by the bottom guide plates to move towards each other in a relatively close direction, thereby bringing the two bottom plates together and supporting the support part through the bottom plates.

[0010] By adopting the above technical solution, when the base plate is located at the bottom of the second conveyor belt, there is a gap between the two opposing base plates for the clamping plate to extend into. The end of the clamping plate near the second conveyor belt extends into the gap between the two opposing base plates. When it is located between the base plate and the top plate, the lower guide plate guides the base plate, thereby moving the two base plates toward a relatively closer direction. The base plate supports the end of the clamping plate away from the first conveyor belt, reducing the situation where the clamping plate is only supported at one end and tilts.

[0011] Optionally, a first groove is provided on the opposite side of the top wall of the abutting portion of the clamping plate, and a first roller is rotatably connected inside the first groove. The first roller abuts against the preparatory plate and is in relative rolling connection with it.

[0012] By adopting the above technical solution, the first roller, which rotates inside the first groove, rolls at the position where the first roller is in contact with the preparation plate, thereby reducing friction between the clamping plate and the preparation plate and reducing frictional wear on the clamping plate.

[0013] Optionally, the support rod is slidably connected to the opening plate, a screw is vertically mounted on the support rod, a driving component for driving the screw to rotate is mounted at the bottom end of the screw, and the screw is threadedly connected to the opening plate.

[0014] By adopting the above technical solution, the screw is driven to rotate by the driving component, and the screw can move the opening plate up and down to adjust the height of the opening plate, thereby adjusting the height of the compaction hammer according to different requirements.

[0015] Optionally, a first slide is provided on the upper part of the second conveyor belt near the material bin. A top block is fixedly connected to the top plate relative to the position of the first slide, and a bottom block is fixedly connected to the bottom plate. The top block and the bottom block are staggered. The first slide gradually tilts towards the opposite side from low to high. The top block can move towards the opposite side under the guidance of the first slide. A second slide is also provided on the side of the second conveyor belt away from the material bin. The second slide gradually tilts towards the opposite side from high to low. The second slide is opposite to the top block. A third slide is provided on the side of the second conveyor belt away from the material bin. The third slide gradually tilts towards the closer side from high to low. The top of the third slide is opposite to the bottom block on the bottom plate when they are opposite to each other, so that the bottom block can move towards the closer side and abut against the top block through the guidance of the third slide.

[0016] By adopting the above technical solution, when the end of the clamping plate near the second conveyor belt extends into the space between the top plate and the bottom plate through the gap between the two opposite bottom plates, and the lower guide plate drives the two opposite bottom plates to move in a relatively close direction, thereby supporting the clamping plate through the bottom plates, and when the top block moves to the position of the second slide, the first slide drives the opposite top block to move in a relatively opposite direction, which facilitates the removal of the clamping plate, and the second slide guides the top block so that the two opposite top blocks move in a relatively close direction and abut against the opposite top plates, and the third slide moves the opposite bottom plates in a relatively opposite direction, so that the bottom plates are in an unfolded state at the bottom end of the second conveyor belt.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. The clamping structure moves upward along the side of the first conveyor belt closest to the material bucket, clamping the hammer and causing it to move upward. When the hammer reaches the position of the opening structure, the opening structure opens the clamping structure, causing the clamping structure and the hammer to disengage, allowing the hammer to fall. The first conveyor belt continues to move the clamping structure, achieving cyclical operation. This improves the ease of operation for test personnel, facilitates rapid test operation, and enhances overall test efficiency.

[0019] 2. When the base plate is located at the bottom of the second conveyor belt, there is a gap between the two opposing base plates for the clamping plate to extend into. The end of the clamping plate closest to the second conveyor belt extends into the gap between the two opposing base plates. When it is located between the base plate and the top plate, the base plate is guided by the lower guide plate, thereby moving the two base plates toward a relatively closer direction. The base plate supports the end of the clamping plate away from the first conveyor belt, reducing the situation where the clamping plate is only supported at one end and tilts.

[0020] 3. When the clamping plate extends into the space between the top plate and the bottom plate through the gap between the two opposite bottom plates, it is driven by the lower guide plate to move the two opposite bottom plates toward a relatively closer direction, thereby supporting the clamping plate through the bottom plates. When the top block moves to the position of the second slide, it is driven by the first slide to move the opposite top block toward a relatively opposite direction, which facilitates the removal of the clamping plate. The second slide guides the top block, causing the two opposite top blocks to move toward a relatively closer direction and abut against the opposite top plates. The third slide moves the opposite bottom plates toward a relatively opposite direction, so that the bottom plates are in an unfolded state at the bottom end of the second conveyor belt.

[0029] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0030] This application discloses an electric compaction hammer device. (Refer to...) Figure 1 , Figure 2An electric compaction hammer device includes a material bin 1, a bottom support structure 2 at the bottom of the material bin 1, a first conveyor belt 3 and a second conveyor belt 4 on both sides of the material bin 1, respectively. A clamping structure 31 is provided on the first conveyor belt 3, and a compaction hammer 5 is vertically arranged between the first conveyor belt 3 and the second conveyor belt 4. The clamping structure 31 can clamp the compaction hammer 5, and the first conveyor belt 3 drives the clamping structure 31 to move upward, so that the clamping structure 31 drives the compaction hammer 5 to move upward. An opening structure 41 is provided on the upper part of the second conveyor belt 4 relative to the clamping structure 31. The opening structure 41 can open the clamping structure 31 to facilitate the disengagement of the compaction hammer 5 from the clamping structure 31.

[0031] The bottom support structure 2 includes horizontally arranged horizontal plates 21, one above the other, and vertically arranged vertical plates 22 between the opposing horizontal plates 21. The vertical plates 22 are fixedly connected to the horizontal plates 21. The length direction of the entire structure is along the line connecting the opposing first conveyor belt 3 and second conveyor belt 4, and the surface of the vertical plates 22 is arranged along the length direction. The material bucket 1 is placed on the upper horizontal plate 21, and the outer diameter of the material bucket 1 is the same as the outer diameter of the horizontal plate 21.

[0032] Reference Figure 1 , Figure 3 The first conveyor belt 3, located near the material bin 1, moves in an upward direction, as does the second conveyor belt 4, also located near the material bin 1. The first and second conveyor belts rotate at the same speed. An emergency stop button is located on one side of the first conveyor belt 3, allowing for quick stopping of the first conveyor belt 3 and ensuring safe construction.

[0033] The compaction hammer 5 includes a clamping part 51 located at the top and a striking part 52 located below the clamping part 51. The clamping part 51 and the striking part 52 are coaxially arranged and fixedly connected, and the outer diameter of the clamping part 51 is larger than the outer diameter of the striking part 52. The top wall of the material barrel 1 has a vertical opening, allowing material to be placed into the material barrel 1 through the opening. The top opening of the material barrel 1 has the same outer diameter as the striking part 52, allowing the striking part 52 to extend into the material barrel 1. The lower side wall of the material barrel 1 has a horizontal vent hole 11, through which the gas inside the material barrel 1 can be discharged after the striking part 52 is inserted into the material barrel 1, facilitating the insertion of the striking part 52.

[0034] The clamping structure 31 includes clamping plates 311 arranged opposite to each other. The clamping plates 311 include arc plates 3111. The arc plates 3111 are arc-shaped structures, and the center of the arc of the arc plate 3111 is coaxial with the center of the clamping part 51. The two opposing arc plates 3111 are hinged to each other at one end near the first conveyor belt 3.

[0035] An abutment portion 3112 is fixedly connected to the side of the arc-shaped plate 3111 near the first conveyor belt 3. The end of the abutment portion 3112 near the first conveyor belt 3 is horizontally slidably connected to the first conveyor belt 3. A first spring 312 is horizontally arranged between the opposing abutment portions 3112, and the first spring 312 is fixedly connected to the abutment portion 3112. A support portion 3113 is fixedly connected to the side of the arc-shaped plate 3111 away from the abutment portion 3112. When the first spring 312 is in a free state, there is a distance between the two opposing abutment portions 3112, and the distance between the two opposing support portions 3113 can pass through the position of the vertical plate 22, thereby abutting against the surface of the second conveyor belt 4.

[0036] A locking block 3114 is fixedly connected to the inner wall of the arc plate 3111. The clamping part 51 of the hammer 5 has a slot 53 relative to the locking block 3114. When the locking block 3114 is located outside the slot 53, the arc plate 3111 moves in a relatively closer direction, so that the locking block 3114 is inserted into the slot 53. A spring plate 531 is horizontally arranged inside the slot 53. A second spring 532 is horizontally arranged on the side of the spring plate 531 away from the locking block 3114. One end of the second spring 532 is fixedly connected to the spring plate 531, and the other end of the second spring 532 is fixedly connected to the hammer 5.

[0037] Reference Figure 2 , Figure 3 A preparation plate 32 is vertically arranged on the lower part of the side of the first conveyor belt 3 near the material barrel 1. Two preparation plates 32 are arranged opposite each other, and a first inclined wall 321 is opened on the side of the two preparation plates 32 that are facing away from each other. The first inclined wall 321 is gradually inclined towards the opposite direction along the height direction from top to bottom. The preparation plate 32 is fixedly connected to the frame of the first conveyor belt 3.

[0038] The tops of the two opposing preparatory plates 32 are spaced apart, and the distance between the inner sidewalls of the bottom ends of the two preparatory plates 32 is the same as the distance between the outer sidewalls of the two opposing abutment portions 3112. This allows the first conveyor belt 3 to move the clamping plate 311 to the bottom end of the preparatory plate 32, so that the two opposing abutment portions 3112 can be moved toward a relatively closer direction by the guide of the preparatory plate 32, thereby moving the arc plate 3111 toward a relatively opposite direction and opening the clamping plate 311.

[0039] The top of the preparation plate 32 is in the same position as the slot 53 when the hammer 5 is inside the material barrel 1. When the clamping plate 311 is disengaged from the top of the preparation plate 32, the first spring 312 pushes the two opposing abutment parts 3112 to move in opposite directions, thereby driving the opposing arc plate 3111 to move in a relatively close direction, extending the clamping block 3114 into the slot 53. Then, the first conveyor belt 3 drives the clamping plate 311 to move upward, driving the hammer 5 to move upward.

[0040] A first groove 313 is formed on the opposite side of the top wall of the abutment portion 3112. A first roller 314 is rotatably connected to the interior of the abutment portion 3112 relative to the first groove 313. The axis of the first roller 314 is arranged along the length direction, and the first roller 314 is opposite to the preparation plate 32. Therefore, when the abutment portion 3112 abuts against the preparation plate 32, the first roller 314 can abut against the preparation plate 32 and roll relative to it.

[0041] Reference Figure 4 , Figure 5 A base plate 42 is horizontally arranged on the second conveyor belt 4. Two base plates 42 are arranged opposite each other and are horizontally slidably connected to the second conveyor belt 4. The upper surface of the base plate 42 and the lower surface of the support part 3113 are opposite each other.

[0042] The second conveyor belt 4 has a top plate 43 horizontally arranged above the bottom plate 42 on the side near the material barrel 1. Two top plates 43 are arranged opposite each other, and the two bottom plates 42 and the second conveyor belt 4 are horizontally slidably connected. There is a gap between the opposite top plate 43 and bottom plate 42, and the gap is the same height as the support part 3113, so that the support part 3113 can extend between the top plate 43 and the bottom plate 42 and rest on the top of the bottom plate 42.

[0043] The second conveyor belt 4 has a vertically arranged lower guide plate 44 on the side near the material bin 1. Two lower guide plates 44 are arranged opposite each other, and the side walls of the two lower guide plates 44 that are close to each other are gradually inclined towards each other from bottom to top. The top of the two lower guide plates 44 are open, and the size of the opening is the same as the width of the two bottom plates 42 after they abut, so that the two bottom plates 42 can slide out from the top of the lower guide plates 44.

[0044] The base plate 42 slides between two opposing lower guide plates 44, and when the base plate 42 is located at the bottom end of the second conveyor belt 4, it is in a relatively separated state. At this time, the support portion 3113 of the clamping plate 311 can enter between the base plate 42 and the top plate 43 from the gap between the two opposing base plates 42. When the base plate 42 moves with the second conveyor belt 4, the two base plates 42 are guided by the lower guide plates 44 to move towards a relatively closer direction, thereby bringing the two base plates 42 into contact with each other. The base plates 42 support the support portion 3113, thereby facilitating the support of the clamping plate 311.

[0045] The opening structure 41 includes a support rod 411 vertically arranged on the upper part of the second conveyor belt 4 near the material barrel 1. An opening plate 412 is sleeved on the top of the support rod 411. Second inclined walls 4121 are opened on both sides of the opening plate 412 along the width direction. The second inclined walls 4121 are gradually inclined towards the relatively close side along the height direction from top to bottom. The bottom end of the opening plate 412 is the same as the gap between the two opposing support parts 3113 along the width direction, so that the inner wall of the two opposing support parts 3113 can abut against the outer wall of the opening plate 412 and slide relative to each other.

[0046] The second inclined wall 4121 of the opening plate 412 causes the opposite support part 3113 to open in a relatively opposite direction. The top wall of the opening plate 412 can cause the opposite support part 3113 to open, thereby disengaging the locking block 3114 from the inside of the locking groove 53, thereby disengaging the compacting hammer 5 from the clamping plate 311, so that the compacting hammer 5 falls into the inside of the material barrel 1 and hammers the material inside the material barrel 1.

[0047] The opening plate 412 and the support rod 411 are slidably connected. A rotating motor 413 is fixedly connected to the support rod 411. A screw 414 is vertically arranged on the support rod 411 relative to the opening plate 412. The screw 414 is threadedly connected to the opening plate 412. The bottom end of the screw 414 is coaxially fixedly connected to the motor shaft of the rotating motor 413.

[0048] By rotating the motor 413, the screw 414 is driven to rotate, which in turn drives the opening plate 412 to move along the height direction, thereby adjusting the height position of the opening plate 412, so that the falling height of the hammer 5 can be adjusted according to different conditions.

[0049] A top block 431 is fixedly connected to the side of the top plate 43 closest to the material bin 1, and a bottom block 421 is fixedly connected to the side of the bottom plate 42 closest to the material bin 1. When the two opposite top plates 43 abut against each other and the two opposite bottom plates 42 abut against each other, the top block 431 and the bottom block 421 are staggered along the height direction. The length of the top block 431 along the length direction is greater than the length of the bottom block 421 along the length direction, and the distance between the two opposite top blocks 431 is greater than the distance between the two opposite bottom blocks 421.

[0050] The opening plate 412 is fixedly connected to a first slide rail 45 on the side near the second conveyor belt 4. Two first slide rails 45 are arranged opposite each other, and the two first slide rails 45 gradually tilt towards the opposite direction along the height direction from low to high. The bottom end of the first slide rail 45 is opposite to the top block 431, so that when the top block 431 moves upward with the top plate 43, the top block 431 can move towards the opposite direction under the guidance of the first slide rail 45, exposing the support part 3113, so that the clamping plate 311 can be moved out from between the top plate 43 and the bottom plate 42.

[0051] The distance between the opposite sides of the two first slide rails 45 is smaller than the distance between the two bottom blocks 421 when the two bottom plates 42 are in contact with each other, so that the bottom blocks 421 can slide out from the outside of the first slide rails 45.

[0052] Reference Figure 2 , Figure 6 An adjusting plate 46 is vertically installed on the side of the second conveyor belt 4 opposite to the first conveyor belt 3. (Refer to...) Figure 6 , Figure 7 The adjustment plate 46 is fixedly connected to the second slide rail 47 on the side near the second conveyor belt 4. Two second slide rails 47 are arranged opposite each other. There is a gap between the second slide rail 47 and the adjustment plate 46. The length of the gap is the same as the length of the top block 431. The second slide rail 47 is gradually inclined towards the opposite direction along the height direction from top to bottom. The top of the second slide rail 47 is opposite to the top block 431 of the two top plates 43 when they are opposite to each other, so that the top block 431 can move and unfold in the opposite direction through the guide of the second slide rail 47.

[0053] A third slide 48 is provided above the second slide 47. The third slide 48 is fixedly connected to the adjusting plate 46, and the third slide 48 is gradually inclined towards the relatively closer direction along the height direction from top to bottom. The top of the third slide 48 is opposite to the bottom block 421 on the base plate 42 when they are facing away from each other, so that the bottom block 421 can move towards the relatively closer direction and abut against the third slide 48. The distance between the outer sides of the two third slides 48 is greater than the distance between the outer sides of the two second slides 47.

[0054] The implementation principle of the electric hammer device for compaction in this application embodiment is as follows: the clamping plate 311 is moved by the first conveyor belt 3, and when the abutting part 3112 of the clamping plate 311 slides against the preparation plate 32, the two opposing abutting parts 3112 move in opposite directions. When the abutting part 3112 and the preparation plate 32 are separated, the first spring 312 pushes the opposing abutting part 3112 to move in opposite directions, and drives the opposing arc plate 3111 to move in a relatively close direction, thereby extending the locking block 3114 into the slot 53, so that the first conveyor belt 3 can drive the clamping plate 311 to move, thereby driving the hammer 5 to move upward.

[0055] When the support part 3113 on the clamping plate 311 is located at the bottom end of the second conveyor belt 4, it enters between the bottom plate 42 and the top plate 43 through the gap between the opposite bottom plates 42, and can drive the two opposite bottom plates 42 to move towards a relatively close direction through the guide plate, thereby supporting the support part 3113 through the bottom plates 42.

[0056] When the clamping plate 311 moves to the position of the opening plate 412, the support part 3113 and the opening plate 412 slide against each other, and then the opposing support part 3113 opens in the opposite direction, disengaging the locking block 3114 from the inside of the locking groove 53, and then the hammer 5 falls down.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
