Description

Technical Field

[0001] The present application relates to the technical field of road construction machinery, and particularly relates to an automatic translation and rotation device for a driver's seat and a paver. Background Art

[0002] A paver is a key device for road construction, mainly composed of a control system, a traveling system, a material feeding system, a material distributing system, and a compaction system. The comfort of the control system is a performance index that users pay more attention to during the use of the paver. Specifically, the convenience of adjusting the operator's seat is related to the user experience of the product. Improving the convenience of product use can reduce the labor intensity of the operator. Therefore, the convenience of adjusting the seat position of the paver plays a crucial role in the operator's experience and is responsible for presenting the comfort of the entire control system of the paver.

[0003] Currently, in order to facilitate the operation on the left and right sides, the seat adjustment device of pavers in the industry generally adopts a technical solution of setting a seat position on each of the left and right sides, and manual adjustment of the seat position is required. This method is not only inconvenient to operate, but also has problems such as poor stability and poor comfort. With the development of modern society, automation and intelligence are the general goals pursued by current industrial products. There is an urgent need for a new technical solution to improve the comfort and operation convenience of the driver's seat of the paver. Summary of the Invention

[0004] Objective: In order to overcome the deficiencies in the prior art, the present invention provides an automatic translation and rotation device for a driver's seat and a paver, which improves the convenience of adjusting the driver's seat of the paver, enhances the comfort of the seat, and reduces the labor intensity of the operator.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0006] In a first aspect, the present invention provides an automatic translation and rotation device for a driver's seat, including a frame, a seat, a translation mechanism, and a rotation mechanism; The translation mechanism is installed inside the frame and includes a first driving device for slidably installing the seat on the frame and causing the seat to perform a translation movement under the drive of the first driving device; The rotation mechanism is installed inside the translation mechanism and is rotatably connected to the bottom of the seat, and includes a second driving device for causing the seat to perform a rotation movement under the drive of the second driving device.

[0007] The first driving device and the second driving device can respectively achieve precise positioning of the translation position and rotation angle of the seat, and can preset the seat position and orientation in different modes. When performing specific operations, one-key control can be performed to simply and quickly adjust the seat to a suitable state.

[0008] In some embodiments, the translation mechanism further includes a base, a first slide rail assembly, and a second slide rail assembly; A rack is provided at the bottom of the frame, and the first slide rail assembly and the second slide rail assembly are installed on the frame in parallel on both sides of the rack; The first slide rail assembly includes a first slide rail and a first slider, and the first slider is nested and slidably installed on the first slide rail; the second slide rail assembly includes a second slide rail and a second slider, and the second slider is nested and slidably installed on the second slide rail; Both ends of the base are respectively installed on the first slider and the second slider.

[0009] The first slide rail assembly and the second slide rail assembly not only provide a supporting force to the base, but also ensure the smooth sliding of the base, thereby enabling the seat to move relative to the frame in a translational manner.

[0010] In some embodiments, the first driving device is installed on the base, and a gear is connected to the output end thereof, and the gear meshes with the rack on the frame.

[0011] The gear meshes with the rack. Since the rack is fixed, the gear rotates and rolls along the rack under the drive of the first driving device, pushing the entire base to move; the first slide rail assembly and the second slide rail assembly are arranged in parallel on both sides of the rack to ensure that the movement path of the base is a straight line.

[0012] In some embodiments, V-shaped grooves are formed on both sides of the first slide rail for limiting the first slider.

[0013] In some embodiments, V-shaped grooves are formed on both sides of the second slide rail for limiting the second slider.

[0014] In some embodiments, it is characterized in that one or more first slide rails are provided.

[0015] In some embodiments, one or more second slide rails are provided.

[0016] In some embodiments, ball bearings are built into both the first slider and the second slider to improve the sliding smoothness.

[0017] In some embodiments, the rotation mechanism further includes a slewing bearing, the outer ring of the slewing bearing is installed on the base, and a mounting seat is installed on the inner ring; A turbine is built into the slewing bearing, and the turbine is fixedly connected to the inner ring of the slewing bearing; A worm is built into the second driving device, the worm is connected to the output end of the second driving device, and meshes with the turbine.

[0018] The output end of the second driving device is connected to a worm, and the worm meshes with a turbine inside the slewing bearing. The worm rotates under the drive of the second driving device to drive the turbine to rotate. Since the turbine is fixedly connected to the inner ring of the slewing bearing, the rotation of the inner ring can be realized, and then the seat can be driven to rotate. The worm and gear structure can achieve a large reduction ratio and provide a large torque; moreover, the rotation of the turbine cannot drive the worm to rotate, which has a certain reverse self-locking property and ensures the stability of rotation.

[0019] In some embodiments, a flange structure is provided on the base, and the seat is flange-connected to the base through a mounting seat.

[0020] In some embodiments, the first driving device is a hydraulic motor or an electric motor, and the second driving device is a hydraulic motor or an electric motor.

[0021] In a second aspect, the present invention provides a paver equipped with the automatic translation and rotation device for the driver's seat as described in the first aspect.

[0022] After the paver is equipped with this automatic translation and rotation device for the driver's seat, the convenience of seat adjustment can be improved, and the working efficiency of the paver can be significantly increased.

[0023] Beneficial effects:

[0024] 1. The automatic translation and rotation device for the driver's seat provided by the present invention can not only translate automatically but also rotate automatically. It not only improves the convenience and comfort of operating the system device but also enhances the control experience of the paver product, which promotes the popularization and promotion of the product and has good economic and social benefits;

[0025] 2. This device integrates the slide rail movement, the rack and pinion movement, and the worm and gear movement, which improves the compactness and reliability of the structure; the driving device is selected from a hydraulic motor or an electric motor, which can be flexibly selected according to the use scenario;

[0026] 3. This device can also be applied to the automatic movement of the mobile platform of other industrial products and has good popularization and application value. Description of the drawings
