Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline dredging, in particular to a dredging device that reduces vibration force during dredging of blocked pipes. Background Art

[0002] Dredging pipelines are an important part of filling construction. When pipelines transport medium such as clay, it is easy to produce balled clay, which will grow bigger and bigger until it blocks the pipeline. In particular, the longer the pipeline is used, the easier it is to cause the pipe wall to be blocked, resulting in cracks, leaks and even bursts, which greatly increases the transportation loss. However, dredging mud pipelines involve underwater pipelines with narrow space, and manual direct entry into dredging mud pipelines for cleaning is prone to safety accidents.

[0003] The existing dredging pipe unblocking devices can move in the pipe, but no shock-absorbing components are provided to reduce the vibration and recoil generated by the drill bit during the unblocking process, which can easily cause the walking mechanism of the unblocking device to shake, reduce the stability of the device, and easily cause the drill bit to be unable to rotate stably for unblocking during operation, thereby reducing the destructive force and reducing the unblocking efficiency. In addition, the drill bit of the existing unblocking device cannot be adjusted with multiple degrees of freedom, which is inconvenient for unblocking blockages at different positions in the pipe. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model aims to propose a dredging device that reduces the vibration force during the dredging of pipe blockages. The dredging device solves the problem that the vibration and recoil generated by the drill bit during the dredging process cannot be alleviated, which easily leads to the dredging device and the dredging pipe wall not fitting together, and the drill bit cannot be adjusted at multiple angles.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A dredging device for reducing vibration force in dredging pipe blockage, comprising a shell, a traveling mechanism, a shock absorbing assembly and a dredging assembly, wherein one end of the shell is connected to the dredging assembly for multi-degree-of-freedom dredging; the traveling mechanism is installed on the end of the shell away from the dredging assembly, and multiple groups of the traveling mechanisms are evenly distributed in the circumferential direction of the shell; a shock absorbing assembly is arranged between the traveling mechanism and the shell to reduce the vibration force and recoil force generated by the drill bit on the traveling mechanism when the drill bit is working;

[0007] The shock absorbing assembly includes a sliding rod, a sliding table and a spring shock absorbing rod. Both ends of the multiple sliding rods are installed on the shell. The sliding table can be slidably mounted on the multiple sliding rods. One end of the spring shock absorbing rod is connected to the walking mechanism, and the other end is connected to the sliding table. The vibration force and recoil force generated by the walking mechanism are transmitted to the sliding table through the spring shock absorbing rod, so that the sliding table slides on the multiple sliding rods.

[0008] Furthermore, the plurality of slide rods are evenly distributed in the circumferential direction of the shell; the slide table is a hollow structure, and the inner wall of the slide table abuts against the shell.

[0009] Furthermore, each group of the walking mechanism includes a crawler track and an adjusting support rod, and both sides of the crawler track are connected to the shell through two adjusting support rods respectively; and both sides of the crawler track are connected to the slide through one spring damping rod respectively.

[0010] Furthermore, one end of the spring damping rod connected to the crawler track is located between two adjustment support rods installed on the same side of the crawler track.

[0011] Furthermore, both ends of the adjusting support rod are fixedly connected to the track and the shell by bolts respectively.

[0012] Furthermore, a motor for driving the drill bit to rotate is provided inside the drill bit, and a drill cutter is provided at the front end of the drill bit.

[0013] Furthermore, the dredging assembly includes a mechanical arm, a drill bit and a turntable, one end of the mechanical arm is connected to the drill bit, and the base of the other end of the mechanical arm is installed on the turntable, and the turntable is rotatably installed on the shell.

[0015] Furthermore, the number of the walking mechanisms is three groups.

[0016] Furthermore, gears for driving the crawler to move and a power source for driving the gears to rotate are installed inside the crawler.

[0017] Compared with the prior art, the dredging device for reducing vibration force in dredging pipe blockage and dredging described in the utility model has the following advantages:

[0018] (1) Compared with the prior art, the dredging device for reducing vibration force during dredging of dredged pipes described in the utility model can move freely in the dredging pipes and can be adjusted according to the different diameters of the pipes to be dredged to meet the specifications of pipelines carried by different dredging vessels; when the dredging device moves to a specified position in the dredging pipe and stops to wait for the drill bit to dredge, the vibration force and recoil force generated can be transmitted to the walking mechanism, and the reaction force generated by the walking mechanism can be transmitted to the shock absorbing component.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] like Figures 1 to 5 As shown, a dredging device for reducing vibration force in dredging pipe blockage and dredging includes a housing 1, a traveling mechanism 2, a shock absorbing assembly 3, a mechanical arm 4, a drill 5 and a turntable 6. One end of the housing 1 is connected to the mechanical arm 4 through the turntable 6, and the mechanical arm 4 is connected to the drill 5; the traveling mechanism 2 is installed on the end of the housing 1 away from the mechanical arm 4, and multiple groups of the traveling mechanisms 2 are evenly distributed in the circumferential direction of the housing 1; a shock absorbing assembly for reducing the vibration force and recoil force generated by the drill bit on the traveling mechanism 2 when working is arranged between the traveling mechanism 2 and the housing 1. When the recoil force generated by the drill bit 5 during dredging is transmitted to the traveling mechanism 2, the reaction force generated by the traveling mechanism 2 is transmitted to the shock absorbing assembly 3, and the shock absorbing assembly 3 reciprocates on the housing 1 to achieve the effect of buffering and shock reduction.

[0033] In a preferred embodiment of the utility model, the shock absorbing assembly 3 includes a slide rod 31, a slide table 32 and a spring shock absorbing rod 33, both ends of the multiple slide rods 31 are installed on the shell 1, and the multiple slide rods 31 are evenly distributed in the circumferential direction of the shell 1; the slide table 32 is a hollow structure, and the slide table 32 can be slidably mounted on the multiple slide rods 31, and the inner wall of the slide table 32 abuts against the shell 1, so that the slide table 32 slides on the multiple slide rods 31; one end of the spring shock absorbing rod 33 is connected to the walking mechanism 2, and the other end is connected to the slide table 32, the vibration force and recoil force generated by the walking mechanism 2 are transmitted to the slide table 32 through the spring shock absorbing rod 33, so that the slide table 32 slides on the multiple slide rods 31.

[0034] In actual use, when the recoil force generated by the drill bit 5 of the dredging device when working is transmitted to the walking mechanism 2 supporting the pipe wall, the walking mechanism 2 will generate a reaction force transmitted to the spring shock absorber rod 33. The stretching of the spring on the spring shock absorber rod 33 will drive the slide 32 to reciprocate on the slide rod 31, thereby releasing energy to achieve the effect of buffering and vibration reduction, thereby improving the stability of the device, reducing damage to the pipe wall, and enabling the drill bit to rotate stably for dredging.

[0035] In a preferred embodiment of the utility model, the number of the walking mechanisms 2 is three. Each group of the walking mechanisms 2 includes a crawler 21 and an adjustment support rod 22, and the crawler 21 is connected to the housing 1 via two adjustment support rods 22 on both sides; and the crawler 21 is connected to the slide 32 via one spring damping rod 33 on both sides.

[0036] One end of the spring damping rod 33 connected to the crawler 21 is located between two adjustment support rods 22 installed on the same side of the crawler 21 to better absorb the reaction force generated by the walking mechanism 2.

[0037] Both ends of the adjusting support rod 22 are fixedly connected to the track 21 and the housing 1 by bolts respectively.

[0038] The crawler belt 21 is internally provided with a gear for driving the crawler belt 21 to move, and a power source for driving the gear to rotate.

[0039] In actual use, in this embodiment, there are three groups of walking mechanisms 2. The staff manually tightens and loosens the bolts connecting the two ends of the support rod 22 with the housing 1 and the crawler 21 in advance according to the diameter of the pipe to be cleared, and changes the diameter of the fitting circle formed by the three groups of crawlers 21 to adapt to the diameter of the pipe to be cleared, so that the crawler 21 can fit tightly to the inside of the pipe. The crawler 21 is a prior art and will not be described in detail here.

[0040] In a preferred embodiment of the present utility model, one end of the mechanical arm 4 is connected to the drill bit 5 , and the base of the other end of the mechanical arm 4 is installed on the turntable 6 , and the turntable 6 is rotatably installed on the housing 1 .

[0041] The mechanical arm 4 is provided with two rotating shafts, namely a first rotating shaft 41 and a second rotating shaft 42 . The mechanical arm 4 is connected to the drill bit 5 via the second rotating shaft 42 , and the drill bit 5 can rotate around the first rotating shaft 41 and the second rotating shaft 42 .

[0042] In actual use, the turntable 6 is existing technology, and a motor is provided inside the shell, which can drive the turntable 6 to rotate, thereby driving the mechanical arm 4 to rotate in a circle, and then driving the drill bit 5 to rotate; the mechanical arm 4 and the drill bit 5 are connected through the No. 1 rotating shaft 41, so that the drill bit 5 can rotate along the No. 1 rotating shaft 41 and the No. 2 rotating shaft 42. Through the turntable 6 and the mechanical arm 4, the drill bit 5 can have multiple degrees of freedom, which is flexible and convenient.

[0043] In a preferred embodiment of the present utility model, a motor for driving the drill bit to rotate is disposed inside the drill bit 5 , and a drill cutter 51 is disposed at the front end of the drill bit 5 .

[0044] In actual use, there is a connecting rod inside the drill bit 5 which is driven to rotate by the motor. The drill bit 51 cuts the blockage by high-speed rotation, which can not only dredge the pipes blocked by stubborn sticky soil balls, but also touch some hard media such as rocks and gravel blocks attached to the clay, thereby greatly improving the dredging efficiency.

[0045] This device can not only effectively solve the blockage problem, but also minimize the secondary damage to the pipeline, which is particularly important when maintaining and servicing pipeline facilities. It not only improves work efficiency but also reduces maintenance costs.

[0046] Working principle of the dredging device to reduce the vibration force during dredging of pipe blockage:

[0047] After the staff detects the location of the pipe blockage, they first dismantle the unblocked pipe in front (because many dredging pipes are not straight, and it is obviously difficult for the dredging device to enter from the beginning), and then control the entire dredging device to enter the congested pipe to carry out dredging work. During dredging, there is no need to completely clear the congested location, as long as the drill bit opens the gap, it can be flushed open by delivering clean water later.

[0048] Before the dredging device enters the pipeline to work, the staff manually tightens the bolts connecting the two ends of the support rod 22 with the shell 1 and the track 21 in advance according to the size of the pipe to be dredged, and changes the diameter of the fitting circle formed by the three groups of tracks 21 to adapt to the diameter of the pipe to be dredged, so that the track 21 can fit tightly against the inside of the pipe, and then the track 21 drives the dredging device to start moving into the pipe.

[0049] After the dredging device reaches the blocked position, the drill bit 5 is started to work, so that the entire drill bit rotates at high speed to cut and break the soil. When the vibration and recoil generated by the drill bit 5 of the dredging device are transmitted to the crawler 21 supporting the pipe wall, a reaction force is generated and transmitted to the spring damping rod 33. The stretching of the spring on the spring damping rod 33 drives the slide 32 to reciprocate on the slide rod 31, thereby releasing energy to achieve the effect of buffering and vibration reduction. After the pipeline is dredged, you can continue to choose to continue cleaning through the walking mechanism 2 or end the work and exit the pipeline.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
