Description

Technical Field

[0001] The invention belongs to the technical field of excavation equipment, and in particular relates to an integrated bucket wheel trench excavation equipment and application thereof. Background Art

[0002] In water network and swamp areas, oil and gas pipelines, water pipelines and other projects that require trenching often use excavators. However, due to the low bearing capacity of the foundation in the water network area, it is difficult to form the trench and large equipment is difficult to enter. Conventional equipment often sinks into the stratum, making it difficult to construct. Currently, the existing construction mainly adopts the following two methods: one is to use a specially made amphibious excavator with widened tracks to appropriately reduce the ground pressure ratio and adapt to a certain degree of soft strata, but in areas with low foundation bearing capacity, there is still a risk of equipment sinking, and large pipelines are difficult to transport and difficult to implement; the second is to adopt auxiliary measures such as foundation replacement, precipitation, diversion, drying, and laying of steel plates, but this method is greatly affected by weather factors, and the project volume is large, the cost is high, and the construction period is long. Summary of the invention

[0003] In order to solve the deficiencies of the prior art, the present invention provides an integrated bucket wheel trench excavation equipment and its application. In the present invention, the screw propulsion vehicle realizes the driving and material transportation functions of heavy equipment in soft strata, and provides power for the trench excavation device. The trench excavation device is located at the rear of the screw propulsion vehicle, and the bucket wheel device is used to cut the slag and transport it to the ground to achieve the designed depth and width of the trench.

[0004] The technical solution provided by the present invention is as follows:

[0008] A pipe clamping mechanism disposed on a side of the bucket wheel away from the work vehicle;

[0009] And an adjusting mechanism for synchronously adjusting the height of the bucket wheel and the pipe clamping mechanism.

[0010] In the above technical solution:

[0011] The spiral propulsion chassis is a hollow spiral structure. As the walking chassis of the work vehicle, it has a large carrying capacity and can carry the work vehicle to realize forward, backward, left turn, right turn and other actions;

[0012] The bucket wheel is driven by hydraulic or fuel to rotate and perform trenching operations;

[0013] The pipe clamping mechanism is used to connect the laid pipes;

[0014] The adjusting mechanism can be used to adjust the bucket wheel up and down to meet the needs of trenching at different depths and speeds.

[0015] Specifically, the working vehicle has a screw propulsion chassis and a hydraulic power assembly. The screw propulsion chassis has two hollow screw propellers, and the hydraulic power assembly drives the two screw propellers to rotate respectively.

[0016] Specifically, the bucket wheel includes:

[0017] Fixed hydraulic motor;

[0018] An inner shaft fixedly connected to the output shaft of the hydraulic motor;

[0019] An outer wheel fixedly connected to the inner shaft via a plurality of radial supports;

[0020] And a plurality of buckets are fixedly arranged around the outer wheel.

[0021] Based on the above technical solution, during the movement of the working vehicle, the bucket wheel is rotated by hydraulic or fuel drive, so that the bucket digs during the rotation, removes mud and rocks, and thus forms a trench.

[0022] Further:

[0023] Each of the buckets is driven by the hydraulic motor to rotate to form a circular coverage area;

[0024] The covered area is coaxial with the rotating shaft of the hydraulic motor;

[0025] The projections of the rotating shaft of the hydraulic motor and the axis of the working vehicle on a horizontal plane are horizontal or collinear.

[0026] Furthermore: the bucket wheel also includes a hood covering each of the buckets located at the top, and a slag channel is provided on the top of the hood, one end of the slag channel is a slag discharge port, which extends toward the covered area, and the other end of the slag channel is a slag port, which faces the side of the bucket wheel.

[0027] Based on the above technical solution, the bucket wheel is a rotationally symmetrical mechanism, the bucket is a trenching actuator responsible for digging the slag, the radial support ensures the trenching size, and the inner shaft drives the bucket to rotate within a certain speed range to ensure that the excavated slag can be discharged smoothly from the slag port. The slag is discharged to one side of the work vehicle without affecting the forward and backward movement of the work vehicle.

[0028] Specifically, the tube clamping mechanism is a hydraulic tube clamping mechanism.

[0029] Specifically, the adjustment mechanism includes a retractable hydraulic cylinder obliquely arranged at the rear of the work vehicle, the retractable portion of the retractable hydraulic cylinder is fixedly provided with a seat body, the seat body is fixedly connected to the bucket wheel, and the bucket wheel is fixedly connected to the pipe clamping mechanism.

[0030] Based on the above technical solution, the bucket wheel can be driven to rise and fall based on the extension and retraction of the hydraulic cylinder, thereby adjusting the working height.

[0031] Furthermore, the projections of the axis of the telescopic hydraulic cylinder and the axis of the working vehicle on the horizontal plane are collinear.

[0032] The present invention also provides the application of the integrated bucket wheel pipe trench excavation equipment for excavating pipe trenches on water networks or swamp areas.

[0033] Specifically, the pipe trench is used for laying pipelines.

[0034] The beneficial effects of the present invention are as follows:
