A back-tilting-preventing device for a dynamic compactor and the dynamic compactor

Abstract

This application discloses an anti-tilting device for a dynamic compaction machine and the dynamic compaction machine itself, relating to the field of dynamic compaction equipment. The anti-tilting device includes a ball joint seat, a support body, and a safety contact edge assembly. The support body is hinged to the ball joint seat, allowing the support body to swing within a certain range of a predetermined horizontal distance, preventing direct rigid collisions between the support body and obstacles on the ground. When the support body contacts an obstacle, as the dynamic compaction machine moves, if the support body exceeds the allowable swing range, the support body will contact the safety contact edge of the safety contact edge assembly, causing the safety contact edge to generate a sensing signal. This signal can be used for audible and visual alarms or to alert personnel to get off the machine and check the situation via the main control system of the dynamic compaction machine, preventing excessive contact between the support body and obstacles and thus avoiding collisions. The dynamic compaction machine of this application includes a dynamic compaction machine body and an anti-tilting device.

Description

Technical Field

[0001] This application relates to the field of dynamic compaction equipment, and more particularly to an anti-tilting device for a dynamic compaction machine and a dynamic compaction machine. Background Technology

[0002] During the operation of a dynamic compaction machine, after compacting one hammer pit, the hammer needs to be moved to the next hammer position. During this process, the dynamic compaction machine will rotate or move. Due to the poor road conditions at the construction site, if the operator is not careful during the relocation, the lower part of the anti-tilt device often hits ground stakes, protruding stones, etc., causing damage. Although current anti-tilt devices typically use telescopic cylinders for extension and retraction support, and can avoid collisions with obstacles by raising the cylinder during movement or rotation, in reality, the operator may need to perform hundreds of movement or rotation operations during the operation. The operator may easily overlook the fact that the telescopic cylinder is not fully raised or not fully extended before moving or rotating. Even when the telescopic cylinder is fully raised, the anti-tilt device is still not very high, and there is still a risk of collision with obstacles. Therefore, regardless of whether the anti-tilt device is fully raised, it may come into contact with obstacles. Thus, the effective solution to this problem is to find ways to avoid damage after contact with obstacles.

[0003] On the other hand, during the construction process, the dynamic compaction machine continuously raises and releases the hammer. When the hammer is suddenly released from a certain height, it loses the balance of the front weight, causing the counterweight end (rear end) of the machine to shake violently downwards. This shaking is even more pronounced when operating with high-energy hammers. Therefore, how to solve the problem of obvious shaking is also an urgent issue to be addressed. Utility Model Content

[0004] This application provides an anti-tilting device for a dynamic compaction machine and a dynamic compaction machine, which can prevent the anti-tilting device from rigidly colliding with obstacles.

[0005] In a first aspect, this application provides an anti-tilting device for a dynamic compaction machine, including a ball joint seat, a support body, and a safety contact edge assembly. The first end of the support body is hinged to the ball joint seat, and the second end is used to support the dynamic compaction machine. The safety contact edge assembly includes a connecting rod, a frame, and a safety contact edge. The two ends of the connecting rod are respectively hinged to the ball joint seat and the frame, and the frame is located on the horizontal side of the support body. The safety contact edge is disposed on the side of the frame facing the support body, and extends along the circumference of the support body. The safety contact edge has a predetermined horizontal distance from the support body.

[0006] Preferably, the support body includes a first ball head, a telescopic member, a second ball head, and a foot plate connected in sequence; the first ball head is hinged to the ball socket of the ball joint seat, the second ball head is hinged to the foot plate, and the foot plate is used to support the dynamic compaction machine.

[0007] Preferably, the telescopic component is configured as a telescopic hydraulic cylinder or an electric push rod.

[0008] Preferably, the safety contact edge and the support body have the predetermined horizontal distance in the horizontal direction, and the predetermined horizontal distance ranges from 2cm to 8cm.

[0009] Preferably, there are multiple safety contact edge components, which are arranged circumferentially around the support body.

[0010] Preferably, the length direction of both the skeleton and the safety contact edge is configured to support the circumference of the body.

[0011] Preferably, the safety contacts of the multiple safety contact components form a ring structure surrounding the support body.

[0012] Preferably, an elastic element is connected between two circumferentially adjacent safety contact edge assemblies, and the two ends of the elastic element are respectively connected to the skeleton of the safety contact edge assembly.

[0013] Secondly, this application provides a dynamic compaction machine, including a dynamic compaction machine body and an anti-tilting device; the ball joint seat of the anti-tilting device is connected to the dynamic compaction machine body.

[0014] Preferably, the dynamic compaction machine also includes a telescopic mechanism, the first end of which is connected to the body of the dynamic compaction machine, and the ball joint seat of the anti-tilting device is connected to the second end of the telescopic mechanism. The telescopic direction of the telescopic mechanism is configured to be the length direction of the body of the dynamic compaction machine.

[0015] The anti-tilting device and dynamic compaction machine of this application have at least the following beneficial effects: The ball joint seat of this application is connected to the dynamic compaction machine. The support body is used to support the dynamic compaction machine and prevent it from tilting backward. The support body is hinged to the ball joint seat, which allows the support body to swing within a certain range of predetermined horizontal distance. This prevents the support body from directly colliding with obstacles on the ground. When the support body comes into contact with an obstacle, as the vehicle body of the dynamic compaction machine moves, the support body exceeds the allowable swing range. The support body will then come into contact with the safety contact edge of the safety contact edge component, causing the safety contact edge to generate a sensing signal. The sensing signal can be used to trigger an audible and visual alarm or to alert the operator to get off the vehicle and check the situation through the main control system of the dynamic compaction machine, thus preventing the support body from having excessive contact with the obstacle and causing a collision.

For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0019] like Figure 1 As shown, this embodiment discloses an anti-tilting device for a dynamic compaction machine and a dynamic compaction machine. The anti-tilting device of this embodiment can be used on a dynamic compaction machine to prevent the dynamic compaction machine from tipping over.

[0020] like Figure 1 As shown, the anti-tilt device 10 includes a ball joint seat 110, a support body 120, and at least one safety contact edge assembly 130, as detailed below: like Figure 2 As shown, the ball joint seat 110 can be directly or indirectly fixed to the dynamic compaction machine. The ball joint seat 110 is provided with a ball socket hole 110a, which is used to connect with the upper ball joint of the support body 120.

[0021] like Figure 3 As shown, the upper end of the support body 120 is provided with a circular first ball head 121, which is located in the ball socket 110a. When the support body 120 is not subjected to external force, the support body 120 hangs down naturally. When the support body 120 comes into contact with an obstacle, the support body 120 can swing in a certain range in the horizontal direction due to the cooperation of the first ball head 121 and the ball socket 110a. The lower end of the support body 120 is used to support the ground to prevent the dynamic compaction machine from tipping over.

[0022] like Figure 4As shown in (A), in this embodiment, the support body 120 includes a first ball head 121, a telescopic member 122, a second ball head 123, and a foot plate 124. The first ball head 121 is fixedly connected to the upper end of the telescopic member 122, and the second ball head 123 is fixedly connected to the lower end of the telescopic member 122. The telescopic member 122 hangs freely without external force. The second ball head 123 is ball-jointed to the foot plate 124. The lower surface of the foot plate 124 is configured as the second end of the support body 120. The foot plate 124 supports the ground, thereby achieving stable support for the dynamic compaction machine. In this embodiment, the telescopic member 122 is configured as a telescopic cylinder or an electric push rod, preferably a telescopic cylinder.

[0023] like Figure 4 As shown in (B), the safety contact edge assembly 130 can generate a corresponding sensing signal after the swing amplitude of the support body 120 exceeds a predetermined range, so as to warn the operator to get off the vehicle to check the abnormal working condition.

[0024] like Figure 5 As shown, the safety contact edge assembly 130 includes a connecting rod 131, a frame 132, and a safety contact edge 133; the upper end of the connecting rod 131 is hinged to the outer wall of the ball joint seat 110, and the lower end of the connecting rod 131 is hinged to the horizontal outer wall of the frame 132; along the horizontal direction (i.e., the radial direction when the telescopic member 122 hangs naturally), the frame 132 is located on one side of the telescopic member 122; the safety contact edge 133 is disposed on the horizontal inner wall of the frame 132, and the horizontal inner wall of the frame 132 is configured as a side wall of the frame 132 facing the telescopic member 122 along the horizontal direction, wherein the safety contact edge 133 and the telescopic member 122 have a predetermined horizontal distance H in the horizontal direction, such as... Figure 4 As shown in (A), the predetermined horizontal distance H ranges from 2cm to 8cm, for example, 3cm or 5cm. Due to the existence of the predetermined horizontal distance H, the entire support body 120 can swing to a certain extent in the horizontal direction. When the swing amplitude exceeds the range of the predetermined horizontal distance H, the outer wall of the telescopic member 122 will contact and press the safety contact edge 133. Since the safety contact edge 133 is a pressure-sensitive element (see the prior art for safety contact edge), it will generate a sensing signal after being pressed. This sensing signal can then be used to warn the operator or as a locking signal to lock related walking or turning movements. Furthermore, the safety contact edge 133 extends a certain length along the circumference of the support body 120. Since the safety contact edge 133 extends along the direction surrounding the support body 120, the swing of the support body 120 can be monitored from multiple angles.

[0025] like Figure 6As shown, in some preferred embodiments, there are multiple safety contact edge components 130. This embodiment illustrates four. The multiple safety contact edge components 130 are arranged around the support body 120 along the circumferential direction. Specifically, the skeleton 132 and safety contact edge 133 of the multiple safety contact edge components 130 extend along the circumferential direction of the support body 120. The end faces of the skeleton 132 of two adjacent safety contact edge components 130 are in contact with each other, and the end faces of the safety contact edge 133 of two adjacent safety contact edge components 130 are in contact with each other.

[0026] like Figure 6 As shown, by setting multiple safety contact edge components 130 around the support body 120, the swing of the support body 120 can be monitored from 360 degrees without blind spots, and the swing monitoring can be carried out after the support body 120 comes into contact with obstacles at various angles.

[0027] like Figure 6 As shown, the length direction of the skeleton 132 is configured to support the circumference of the body 120, and its overall shape is arc-shaped. The length direction of the safety contact 133 is configured to support the circumference of the body 120, and its overall shape is arc-shaped. Since both the skeleton 132 and the safety contact 133 are arc-shaped and have the same length, the skeleton 132 and the safety contact 133 of the multiple safety contact assemblies 130 can surround the support body 120.

[0028] like Figure 6 As shown, furthermore, the safety contacts 133 of the multiple safety contact components 130 sequentially contact each other in the circumferential direction, forming a ring structure surrounding the support body 120. This ring structure is a complete circle and is coaxial with the support body 120 in its naturally drooping state. The ring structure formed by the multiple safety contacts 133 allows for comprehensive monitoring of the swaying of the support body 120. It should be noted that, as... Figure 3 As shown, when the telescopic member 122 of the support body 120 touches the safety contact edge 133, the contact distance L between the first ball head 121 and the end face of the ball socket hole 110a is greater than 0. Therefore, the first ball head 121 and the telescopic member 122 can continue to swing and squeeze the safety contact edge 133 to avoid the first ball head 121 and the telescopic member 122 getting stuck.

[0029] In this embodiment, preferably, such as Figure 5 As shown, the frame 132 is provided with a clamping groove 132a, and the safety contact edge 133 is provided with a clamping part 1331. The clamping part 1331 is clamped and connected within the clamping groove 132a, thereby making the frame 132 and the safety contact edge 133 stably connected together. In some other embodiments, the frame 132 and the safety contact edge 133 can also be connected by adhesive bonding.

[0030] like Figure 6 As shown, in this preferred embodiment, at least one elastic element 140 is connected between two circumferentially adjacent safety contact edge assemblies 130. The elastic element 140 is configured as a spring. Specifically, the first end of the elastic element 140 is connected to the outside of the skeleton 132 of one safety contact edge assembly 130, and the second end of the elastic element 140 is connected to the outside of the skeleton 132 of the other safety contact edge assembly 130. After the telescopic member 122 of the support body 120 compresses the safety contact edge 133 and the skeleton 132, the corresponding elastic element 140 will be stretched, and the annular structure formed by the multiple safety contact edges 133 will open appropriately, which can prevent the safety contact edges 133 from being excessively compressed and damaged. When the telescopic member 122 of the support body 120 disengages from the safety contact edge 133, the annular structure formed by the multiple safety contact edges 133 will reset and close together under the action of the elastic element 140.

[0031] The anti-tilt device in this embodiment works on the following principle: like Figure 4 As shown, during the movement of the dynamic compaction machine, if the support body 120 comes into contact with an obstacle on the ground, the first ball head 121 of the support body 120 will rotate around the upper ball joint seat 110 accordingly. As the dynamic compaction machine moves, the support body 120 swings horizontally relative to the dynamic compaction machine. If the dynamic compaction machine continues to move after the swing amplitude of the support body 120 exceeds the predetermined range, the telescopic member 122 of the support body 120 will contact and press the safety contact edge 133. The safety contact edge 133 generates a sensing signal, which can be used to alarm, prompt, or lock the corresponding action of the dynamic compaction machine to avoid the support body 120 from being damaged by collision.

[0032] like Figure 7 and Figure 8 As shown, this embodiment also discloses a dynamic compaction machine, which includes a machine body 20 and an anti-tilting device 10; the ball joint seat 110 of the anti-tilting device 10 is connected to the machine body 20. The machine body 20 of this embodiment refers to the prior art and includes a vehicle body, a main system, a support arm, a lifting device, a hammer, etc. The ball joint seat 110 of the anti-tilting device is connected to the vehicle body; the safety contact edge 133 is electrically connected to the main system. The dynamic compaction machine of this embodiment has strong stability. Before the anti-tilting device 10 contacts an obstacle and undergoes a rigid collision, it can generate a sensing signal and send it to the main system, which can then prompt the operator or lock the corresponding action.

[0033] like Figure 8As shown in the preferred embodiment, the dynamic compaction machine further includes a telescopic mechanism 30. The anti-tilting device 10 is connected to the rear end of the dynamic compaction machine's body via the telescopic mechanism 30. One end of the telescopic mechanism 30 is connected to the body, and the ball joint seat 110 of the anti-tilting device is connected to the second end of the telescopic mechanism 30. The telescopic direction of the telescopic mechanism 30 is configured to be along the length of the body. When support is needed, the telescopic mechanism 30 moves the anti-tilting device away from the body, increasing the distance between the support point and the machine's rotation center. This results in a smaller impact torque from the sudden release of the same weight of hammer on the support body 120, significantly extending its service life and making the entire machine more stable.

[0034] like Figure 8 As shown, in some preferred embodiments, the telescopic mechanism 30 includes an outer frame beam 310, an inner frame beam 320, and a drive cylinder 330. The outer frame beam 310 is fixedly mounted on the vehicle body or rotating platform of the dynamic compaction machine. The inner frame beam 320 is slidably mounted inside the outer frame beam 310, with the sliding direction consistent with the length direction of the vehicle body. The two ends of the drive cylinder 330 are respectively hinged to the outer frame beam 310 and the inner frame beam 320, and the telescopic direction of the drive cylinder 330 is consistent with the length direction of the vehicle body. The ball joint seat 110 of the anti-tilt device is connected to the end of the inner frame beam 320. When the inner frame beam 320 slides relative to the outer frame beam 310 in the length direction of the vehicle body, the anti-tilt device slides together with the inner frame beam 320.

[0035] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
