Description

Technical Field

[0001] This invention relates to a remote control box for a paver and a paver, belonging to the field of paver equipment. Background Technology

[0002] A paver is a construction equipment mainly used for paving various materials for the base and surface layers of roads. It spreads asphalt and concrete materials evenly on the road surface and pre-compacts and shapes them to a certain extent to form the asphalt or concrete base or surface layer.

[0003] The performance of a paver's leveling system directly determines the smoothness of the paved road surface. Existing pavers are multi-person collaborative road construction machines, and their leveling systems mostly employ a separate design with a leveling controller and a remote control box. The leveling controller is used for automatic leveling, while the remote control box is used for manual leveling. The remote control box is generally installed on the left or right end plates of the screed for convenient close-range control by the operator from both sides of the screed; it is also called a side control box or side control device. This separate design has the following disadvantages: (1) The complex connection and numerous components of the split automatic leveling system not only increase the preparation time before construction, but also cause downtime due to connection problems during construction, resulting in low overall construction efficiency. (2) Each paver needs to be equipped with two leveling controllers and two remote control boxes, which increases the equipment cost. If a fault occurs, the cost of repair or replacement is also relatively high. Summary of the Invention

Detailed Implementation

[0018] The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or apparatuses. The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Example 1

[0019] This embodiment provides a remote control box for a paver, such as... Figure 1 As shown, the remote control box includes: remote control box body 1, frequency conversion leveling control module and bracket 2.

[0020] The remote control box body 1 is a button box. In addition to the control buttons configured in a normal paver remote control box, its surface is also equipped with two sets of leveling control buttons, which are used to control the leveling sensors on both sides of the paver.

[0021] The leveling control buttons on the remote control box body 1 are connected to the frequency conversion leveling control module and the paver's vehicle controller signals via the CAN bus.

[0022] The remote control box in this embodiment integrates the functions of the remote control box and leveling controller of a traditional paver into one unit. Operators only need to operate the remote control box provided by this invention to complete all the operations of the remote control box and leveling controller of a common paver, which greatly improves the convenience of use.

[0023] In practical applications, the integrated remote control box provided in this embodiment is installed on both sides of the ironing board, and the bracket of the integrated remote control box is fixedly installed on the ironing board. The operator can control the leveling of both sides at the same time using the remote control box on one side.

[0024] The bracket 2 is the core connecting component of the entire remote control box, responsible for connecting various functional modules. The frequency conversion leveling control module is located inside the bracket 2, which further simplifies the structure of the remote control box and improves the system integration.

[0025] The bracket 2 is equipped with a socket assembly 4 for accessing the bus. The leveling sensor of the paver is connected to the frequency conversion leveling control module and the paver's vehicle controller through the socket assembly 4.

[0026] like Figure 2 As shown, in some embodiments, the leveling sensor includes a height leveling device and a cross slope leveling device; correspondingly, the socket assembly 4 on the bracket of the single-sided remote control box includes a first socket for connecting the height leveling device and a second socket for connecting the cross slope leveling device.

[0027] It should be noted that both remote control boxes can be connected to the slope leveling instrument, but the slope leveling instrument can only be connected to one remote control box. That is, if one remote control box is selected to connect to the slope leveling instrument, the other remote control box cannot be selected to connect to the slope leveling instrument at the same time.

[0028] In some specific embodiments, the height leveling instrument is an ultrasonic slipper or corner sensor. However, since the ultrasonic slipper or corner sensor can only be recognized and used by the remote control box on one side, an ultrasonic slipper or corner sensor is installed on each side of the paver screed and connected to the remote control boxes on the left and right sides respectively.

[0029] This design ensures the specialization of the sensors, avoids interference between different sensors, and improves leveling accuracy.

[0030] In some embodiments, the two sets of leveling control buttons on the remote control box body 1 each include four illuminated buttons: manual / automatic switch button, leveling up button, leveling down button, and zeroing button.

[0031] Specifically, the manual / automatic switch button is used to select between manual leveling mode and automatic leveling mode. For example, the button light indicates that it is in automatic leveling mode, while the button light is off indicates that it is in manual leveling mode.

[0032] When the manual / automatic switch is in manual leveling mode, the leveling up button adjusts the leveling cylinder upwards, while the leveling down button adjusts it downwards. When the manual / automatic switch is in automatic leveling mode, the leveling up button increases the automatic leveling reference value, while the leveling down button decreases it. The flashing frequency of the indicator lights for the leveling up and leveling down buttons matches the driving frequency of the corresponding solenoid valves.

[0033] The zeroing button is used to set the current measurement value of the leveling sensor as the reference value, or to zero out both the measurement value and the reference value of the leveling sensor.

[0034] As an example, a long press of the zeroing button is configured to zero the leveling sensor's measured value and reference value, while a short press of the zeroing button is configured to set the leveling sensor's current measured value as the reference value.

[0035] In some embodiments, the bracket is also provided with an emergency stop switch 3 and a warning light 7.

[0036] The integrated remote control box for pavers provided in this embodiment, through its modular design and built-in frequency conversion leveling control module, not only improves the ease of operation but also reduces leveling costs, enhances the adaptability and versatility of the equipment, and has broad application prospects. Example 2

[0037] Based on Embodiment 1, this embodiment provides a remote control box for a paver that includes a display module.

[0038] like Figure 1 and Figure 3 As shown, the display module includes a display 5 and a setting key 6; the display module is installed on one side of the remote control box body 1.

[0039] In this embodiment, the display module is fixedly connected to one side of the remote control box body 1 via a connecting shaft. The two are connected together as a whole to the bus and are connected to the frequency conversion leveling control module and the paver's vehicle controller signal.

[0040] The display 5 is configured to set the allowed sensor types and integrated leveling sensitivity according to the selection signal of the setting key 6, as well as to turn the integrated leveling function on or off.

[0041] As an example, Figure 4 The main page of display 5 on the left remote control box is shown. After turning the page on the main page of display 5 using the F6 key, you can enter the integrated leveling settings page. On this page, you can choose to enable or disable the integrated leveling function. If the integrated leveling function is enabled, you can further set the type of leveling sensor connected to the left remote control box. You can switch the options using the F8 key: "No sensor selected", "Digital corner sensor", "Ultrasonic slipper ground mode", "Ultrasonic slipper alignment mode", and "Digital cross slope sensor". You can also set the integrated leveling sensitivity, which is adjustable from 1 to 10 levels. Example 3

[0042] This embodiment, also based on Embodiment 1, provides a remote control box for a paver that includes a display module. However, unlike Embodiment 2, in this embodiment, the display module is mounted on one side of the remote control box body 1 via a detachable connector. The two are detachable and each is connected to a bus. For this purpose, corresponding display sockets and button sockets are provided on the bracket 2, so that the display module and the remote control box body 1 are connected to the bus respectively, and both are independently connected to the frequency conversion leveling control module and the paver's vehicle controller signal.
