Description

Technical Field

[0001] The invention relates to a ground preparation facility in water conservancy construction, in particular to a ground surface tamping device for water conservancy construction. Background Art

[0002] Surface treatment is an essential part of most engineering construction processes. Its purpose mainly involves two aspects. One is to provide a solid soil foundation for construction, improve the bearing capacity of the ground, enable the ground to bear heavier loads, and avoid risks such as settlement and collapse that may occur in later buildings. The other is to provide convenience for construction and facilitate the construction operations of engineering equipment and staff.

[0003] During the construction of water conservancy projects, surface tamping is also an indispensable link. The corresponding carrier of water conservancy projects is water flow. If the ground is not handled properly, problems such as settlement and collapse are very likely to occur, especially in the channel part of the water conservancy project. If the surface in the channel is not compact, the channel will be eroded by water flow in the later stage, resulting in channel collapse, soil erosion and other problems. For channels with channel plates, it is even more necessary to effectively handle the surface. If the bottom and slope of the channel are not handled properly, when the channel plate is laid later, whether it is a prefabricated channel plate or a cast channel plate, the ground is not compact enough and the support for the channel plate will be lacking, and the channel will be damaged in subsequent use.

[0004] The surface tamping equipment currently used in water conservancy projects is still the same equipment used in other engineering construction operations. However, water conservancy projects are different from other projects. For example, in the channel construction described above, there are inclined slopes on both sides of the channel, which makes tamping difficult. It is difficult to achieve the desired effect using existing general equipment. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a ground surface tamping device for water conservancy construction, which adopts a structure in which multiple tamping plates cooperate with each other. The angles of the tamping plates are adjusted by brackets to achieve the effect of synchronously tamping slopes at different angles.

[0006] The present invention adopts the following technical solutions: A ground tamping device for water conservancy construction comprises a plurality of tamping plates, which are supported, connected and limited by brackets, and the tamping plates are driven by the brackets to adjust their angles and change their positions; a hydraulic tamping part is also provided on the tamping plates, and the hydraulic tamping part acts on one of the tamping plates, while the remaining tamping plates tamping the ground surface in a follow-up manner through the brackets.

[0007] Furthermore, the ramming plates are provided with three pieces, the middle ramming plate is supported on the ground, and the other two ramming plates are respectively arranged on both sides of the middle ramming plate; the bracket includes a fixed rod and several groups of hydraulic telescopic rods, a guide plate is also provided on the upper part of the ramming plate, the side ramming plates and the guide plates are connected by the fixed rod, and the ramming plates, guide plates and fixed rods are provided with multiple groups of hydraulic telescopic rods, which support and adjust various parts; the lifting and lowering of the guide plate is controlled by the hydraulic telescopic rod, and the guide plate drives the top of the fixed rod to move up and down to adjust the opening of the ramming plates on both sides, and the angle adjustment of the ramming plates on both sides is controlled and adjusted by the hydraulic telescopic rod.

[0008] Furthermore, the guide plate and the middle ramming plate are supported and connected by a hydraulic telescopic rod, the middle ramming plate and the outer ramming plates are supported and connected by a hydraulic telescopic rod, and a hydraulic telescopic rod is provided between the center of the fixed rod and the middle ramming plate; two hinge points are provided on the side ramming plates, corresponding to the fixed rod and the hydraulic telescopic rod respectively, and the two hinge points are spaced a distance apart.

[0009] The hydraulic tamping part is arranged at the upper center of the middle tamping plate, and the hydraulic tamping part is arranged vertically; a horizontal strip-shaped slot hole is arranged at the center of the guide plate. When the guide plate is lowered to below the top of the hydraulic tamping part, the hydraulic tamping part passes through the slot hole on the guide plate, and the slot hole allows the hydraulic tamping part to move left and right inside it.

[0010] The hydraulic tamping part includes a frame, a hydraulic telescopic rod, a rammer, and an auxiliary rammer plate. The auxiliary rammer plate is arranged at the bottom of the frame, the hydraulic telescopic rod and the rammer are arranged inside the frame, the hydraulic telescopic rod is arranged at the center of the top of the frame, and the rammer is arranged at the bottom of the hydraulic telescopic rod; the bottom of the auxiliary rammer plate is fixedly connected to the top of the center of the middle rammer plate; a hydraulic system is also arranged above the middle rammer plate, and the hydraulic system controls each hydraulic telescopic rod.

[0011] The two sides of the middle tamping plate are respectively provided with clamping grooves, and the inner sides of the tamping plates at the two sides are provided with clamping plates corresponding to the clamping grooves.

[0012] Furthermore, a pull rod is provided on the auxiliary tamping plate of the hydraulic tamping part, and a square ring-shaped pressure plate is provided above the guide plate. The center of the pressure plate corresponds to the hydraulic tamping part, and the four sides of the pressure plate are supported to the upper part of the guide plate. The pull rod connects the pressure plate, and a locking member for locking and releasing the pull rod is also provided on the pressure plate.

[0013] The pressure plate is provided with a through hole corresponding to the pull rod, and the pull rod and the through hole are provided with corresponding groups; the locking piece includes a hydraulic telescopic rod and a wedge block, one side of the through hole is provided with an inclined groove corresponding to the wedge block, and the wedge block is inserted into the inclined groove. When the wedge block is inserted into the inclined groove, one side of the wedge block fits with the pull rod; an L-shaped bracket is provided at a position corresponding to the inclined groove on the pressure plate, the hydraulic telescopic rod is provided at the lower part of the bracket, and the bottom of the hydraulic telescopic rod is connected to the upper part of the wedge block; an inverted T-shaped guide rod is provided at the bottom of the hydraulic telescopic rod, and a slide groove corresponding to the guide rod is provided on the wedge block. When the wedge block is inserted into the inclined groove under the action of the hydraulic telescopic rod, its lateral sliding is achieved by the cooperation of the slide groove and the guide rod.

[0014] The present invention adopts the above technical solution to achieve the following beneficial effects: 1. The tamping plate of this device can be adjusted in angle and position. When it is used in the construction of water conservancy projects, the tamping plate can be adjusted according to the construction channel so that the tamping plate corresponds to the bottom surface and slope surface of the channel respectively, and then the synchronous surface tamping operation is performed; 2. The fixed rod and the fixed pull rod structure can reduce the impact damage to the hydraulic telescopic rod caused by the rammer during the tamping operation in actual use. The rammer of the hydraulic tamping part has a large impact force during the working process. If the hydraulic telescopic rod is used to bear the impact, the practical life of the hydraulic telescopic rod will be shortened. The setting of the fixed rod and the pull rod structure greatly reduces the risk. The hydraulic telescopic rod is more responsible for the functions of angle adjustment and limit, which guarantees the service life to a certain extent. 3. The overall support structure of the device can be flexibly adjusted during use, that is, the side tamping plates can be adjusted, and the middle tamping plates can be raised. The walking effect can be achieved by controlling the support and fall of multiple tamping plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described below in conjunction with embodiments. The embodiments are only one or more manifestations of the present invention. In practical applications, improvements known to those skilled in the art made on the basis of the technical solutions described in the present invention should all fall within the scope of protection claimed by the present invention. Example

[0023] like Figure 1-Figure 4 A ground surface tamping equipment for water conservancy construction is shown, which includes three tamping plates 1, namely a main tamping plate 101 and two side tamping plates 102. A guide plate 2 is provided above the main tamping plate 101, a hydraulic tamping part 3 is provided at the center of the upper part of the main tamping plate 101, and a slot hole 201 corresponding to the hydraulic tamping part 3 is provided at the center of the guide plate 2. When the guide plate 2 is lifted and lowered and moved left and right, the hydraulic tamping part 3 corresponds to the slot hole 201.

[0024] The main tamping plate 101 , the side tamping plate 102 and the guide plate 2 are integrally connected and fixed by a bracket 4 , and the movement and adjustment of each part are realized by the bracket 4 .

[0025] The bracket 4 includes a fixed rod 401 and a plurality of hydraulic telescopic rods 402. A first hydraulic telescopic rod 402a is provided between the guide plate 2 and the main ramming plate 101. The top and bottom of the first hydraulic telescopic rod 402a are respectively hinged at the center of the guide plate 2 and the main ramming plate 101; the top of the fixed rod 401 is hinged to the guide plate 2, and the bottom of the fixed rod 401 is hinged to the side ramming plate 102. A second hydraulic telescopic rod 402b is provided between the main ramming plate 101 and the side ramming plate 102. Both ends of the second hydraulic telescopic rod 402b are respectively hinged to the main ramming plate 101 and the side ramming plate 102. Two hinge points are provided on the side ramming plate 102, which correspond to the fixed rod 401 and the second hydraulic telescopic rod 402b respectively. The first hydraulic telescopic rod 401a and the second hydraulic telescopic rod 402b are hinged to the main ramming plate 101. the hinge points of the two fixed rods 401 and the guide plate 2 are arranged on both sides of the hinge point of the first hydraulic telescopic rod 401a and the guide plate 2.

[0026] A third hydraulic telescopic rod 402 c is further provided in the bracket 4 . One end of the third hydraulic telescopic rod 402 c is hinged to the center of the fixed rod 401 , and the other end is hinged to the main tamping plate 101 .

[0027] The hydraulic tamping part 3 includes a frame 301, a hydraulic telescopic rod 302 of the tamping part, a rammer 303, and an auxiliary tamping plate 304. The auxiliary tamping plate 304 is arranged at the bottom of the frame 301, the hydraulic telescopic rod 302 of the tamping part and the rammer 303 are arranged inside the frame 301, the hydraulic telescopic rod 302 of the tamping part is arranged at the center of the top of the frame 301, and the rammer 303 is arranged at the bottom of the hydraulic telescopic rod 302 of the tamping part; the bottom of the auxiliary tamping plate 304 is fixedly connected to the top of the center of the main tamping plate 101; a hydraulic system 5 is also arranged above the main tamping plate 101, and the hydraulic system 5 controls each hydraulic telescopic rod.

[0028] The main tamping plate 101 is provided with clamping grooves 103 on both sides thereof, and the inner side of the side tamping plate 102 is provided with clamping plates 104 corresponding to the clamping grooves 103 .

[0029] When the present embodiment is in use, the fixed rod 401 in the bracket and the hydraulic telescopic rods 402 connect and drive the main tamping plate 101, the side tamping plates 102 and the guide plate 2. The lifting and lowering of the first hydraulic telescopic rod 401a drives the guide plate 2 to lift and lower. The lifting and lowering of the guide plate 2 will drive the inclination angle of the fixed rod 401 to change. The change in the inclination of the fixed rod 401 brings about a change in the opening of the two side plates 102. In actual use, it can be used for rivers of different widths. The extension and retraction of the second hydraulic telescopic rod 402b will adjust the angle of the side tamping plate 102. The length of the fixed rod 401 is a fixed structure. Therefore, the angle of the side tamping plate 102 can be adjusted by combining the changes of the low hydraulic telescopic rod 402b and the third hydraulic telescopic rod 402c.

[0030] After the side tamping plate 102 is supported on the slope of the river channel, after the length of each hydraulic telescopic rod 402 is fixed, the hydraulic tamping part 3 is started, and the hydraulic telescopic rod 302 of the tamping part lifts the tamping hammer 303 and hits it downward, giving the auxiliary tamping plate 304 a downward hammering, and then drives the main tamping plate 101 to tamp the surface. At the same time, the downward tamping force of the main tamping plate 101 is transmitted to the side tamping plate 102 through the bracket 4, so that the side tamping plate 102 also tamps the slope of the channel. When the opening of the side tamping plate 102 is greater than the width of the main tamping plate 101, the area covered by the main tamping plate 101 on the channel ground is limited. At this time, it is necessary to control the hydraulic telescopic rod 402 to lift and move the main tamping plate for further tamping, and finally achieve the effect of completely covering the entire channel.

[0031] The above is the workflow for compaction operation on the channel. In addition, the device can also be used to level the ground. Through the cooperation of the fixed rod 401 in the bracket 4 and the hydraulic telescopic rods 402, the side tamping plate 102 can be horizontally attached to the side of the main tamping plate 101. At this time, the clamping plate 104 on the side tamping plate 102 is inserted into the clamping groove 103 on the side of the main tamping plate 101. The main tamping plate 101 and the side tamping plate 102 form a flat plane, and the compaction operation of the level ground is realized through the operation of the hydraulic tamping part 3.

[0032] In addition, the main tamping plate 101 and the side tamping plate 102 in the device can be reciprocated and lifted under the drive of the bracket 4. When the side tamping plates 102 on both sides are supported on the ground together, the main tamping plate 101 is raised and moved to one side to be supported on the ground by controlling the hydraulic telescopic rod 402, and then the side tamping plates 102 on both sides are lifted and moved in the same direction and supported on the ground. Figure 4 As shown, the automatic walking of the equipment is achieved by reciprocating. Example

[0033] The overall structure of this embodiment is similar to that of embodiment 1. The difference is that the driving mode of the hydraulic tamping part 3 on the guide plate 2 is changed in this embodiment. Figure 5-Figure 7 .

[0034] In Example 1, the driving of the guide plate 2 by the hydraulic tamping part 3 is achieved by tightening the hydraulic telescopic rod 402. In this embodiment, a pull rod 6 and a pressure plate 7 are added. The pressure plate 7 corresponds to the top of the guide plate 2. The pull rod 6 pulls it, and a corresponding locking member 8 is provided on the pressure plate 7, so that the pull rod 6 and the pressure plate 7 can be locked at different heights. When the guide plate 2 is raised or lowered to different heights, the driving of the guide plate 2 by the hydraulic tamping part 3 can be achieved by locking the pull rod 6 and the pressure plate 7.

[0035] The locking operation of the locking member 8 is achieved through the cooperation of the wedge block 801 and the pull rod 6. A slot hole 701 corresponding to the pull rod 6 is provided on the pressure plate 7. An inclined groove 702 corresponding to the wedge block 801 is provided on one side of the slot hole 701. The wedge block 801 is inserted into the inclined groove 702. The wedge block 801 is inserted tightly in the inclined groove 702 so that one side of it supports and presses the pull rod 6, thereby achieving the limiting between the pull rod 6 and the pressure plate 7; the bottom of the pull rod 6 is connected to the auxiliary ramming plate 304 of the hydraulic locking part 3.

[0036] The insertion and withdrawal of the wedge block 801 in the inclined groove 702 is achieved by driving the locking hydraulic telescopic rod 802. An L-shaped bracket 803 is provided on the pressure plate 7 near the inclined groove 702. An inverted T-shaped guide rod 804 is provided at the bottom of the locking hydraulic telescopic rod 802. A corresponding slide groove 805 is provided on the top of the wedge block 801. When the wedge block 801 provides sliding support for the pull rod 6 in the inclined groove 702, the slide groove 805 slides on the guide rod 804.

[0037] In this embodiment, when the hydraulic tamping part 3 performs the tamping operation, the guide plate 2 is driven by the pull rod 6 and the pressure plate 7 .

[0038] The above two embodiments are two forms of expression of the present invention, and the difference between them lies in that for the driving of the guide plate 2, the main tamping plate 101 is directly driven by the hydraulic tamping part 3, while the side tamping plate 102 is not directly connected to the hydraulic tamping part 3, and belongs to a driven tamping structure. Therefore, the tamping operation of the side tamping plate 102 is mainly achieved through the linkage of the guide plate 2 to the fixed rod 401.

[0039] In Example 1, the drive between the guide plate 2 and the hydraulic tamping part 3 is actually achieved by the first hydraulic telescopic rod 402a. The driving structure generates a large pressure on the first hydraulic telescopic rod 402a. The impact during the operation of the hydraulic tamping part 3 is transmitted to the guide plate 2 through the first hydraulic telescopic rod 402a. Multiple impacts are likely to cause damage to the telescopic rod, affecting the service life. Therefore, we added the relevant structures of the pull rod 6 and the pressure plate 7 in Example 2. The main purpose is to reduce the impact of the hydraulic tamping part 3 on the telescopic rod during the operation of the hydraulic tamping part 3. The driving effect of the hydraulic tamping part 3 on the guide plate 2 is transmitted through the pull rod 6 and the pressure plate 7. Combined with the support of the fixed rod 401 on the side tamping plate 102, the impact is transmitted more through the fixed structure, minimizing the impact on the telescopic rods of each part.
