Description

Technical Field

[0001] This application relates to the field of coal transport trolleys, and more specifically, to a mobile coal conveying and unloading trolley. Background Technology

[0002] As a short-distance transportation tool in coal mines, the safety performance of mobile coal conveying trolleys directly affects the efficiency and fullness of coal resource transfer. The challenge in remotely controlling mobile coal conveying and unloading trolleys lies in the communication design during movement. One approach is a sliding line or reel-type communication cable design. With a sliding line design, the communication information carrier is transmitted via a sliding line; with a communication cable, the communication information carrier is transmitted via a communication cable. Due to the long communication distance, the communication cable is usually wound and unwound using a cable reel or tank chain. Another approach is a wireless carrier communication design. Wireless carrier communication typically uses a 400-470MHz carrier module loaded with RS485 communication information carriers for communication.

[0003] Currently, the coal transport trolleys that travel along the track are mainly composed of a base frame, track wheels, and a carriage. Some also have a lifting and tilting unloading mechanism. However, after the trolleys have been used multiple times, either the carriage or the moving base frame will malfunction and become damaged. Replacing the entire trolley is not only costly, but the lifting and tilting unloading mechanism is not stable enough and poses a risk of the trolley tipping over. Utility Model Content

Detailed Implementation

[0033] 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 some embodiments of this application, and not all embodiments.

[0034] Please see Figures 1-4 This application provides a mobile coal conveying and unloading trolley, including a moving component 100 and an unloading component 200.

[0035] Please see Figure 1 and 2 The moving component 100 includes a frame 110, a rotating rod 120, a track wheel 130, and a first servo motor 140. The rotating rod 120 is rotatably mounted on the bottom of the frame 110, the track wheel 130 is mounted on the end of the rotating rod 120, and the first servo motor 140 is mounted on the bottom of the frame 110 and is connected to the rotating rod 120 for transmission.

[0036] The frame 110 has a fixing plate 111 at the bottom, through which the rotating rod 120 rotates. The fixing plate 111 is used to cooperate with the bearing to rotate and install the rotating rod 120, and to support the stable rotation of the rotating rod 120.

[0037] Specifically, a gear chamber 150 is provided at the bottom of the frame 110. The gear chamber 150 contains a driving gear 151 and a driven gear 152. The driving gear 151 is fixedly connected to the output end of the first servo motor 140, and the driven gear 152 is fixedly sleeved on the rotating rod 120. By setting the driving gear 151 and the driven gear 152, when the first servo motor 140 is turned on, the first servo motor 140 drives the driving gear 151 to rotate. The driving gear 151 meshes and drives the driven gear 152 to rotate. The driven gear 152 drives the rotating rod 120 to rotate, thus realizing the transmission connection.

[0038] Please see Figure 1 , 23 and 4, the unloading assembly 200 includes an adjusting component 210, a connecting plate 220, a carriage 230, an unloading cylinder 240, an unloading impeller 250, a second servo motor 260, and a controller 280. The adjusting component 210 is disposed inside the frame 110, the connecting plate 220 is disposed on the top of the adjusting component 210, the carriage 230 is installed on the connecting plate 220, the unloading cylinder 240 is fixedly inserted through the carriage 230, the unloading impeller 250 is rotatably disposed inside the unloading cylinder 240, the second servo motor 260 is installed on the outside of the unloading cylinder 240 and is drivenly connected to the unloading impeller 250, and the controller 280 is installed on the outside of the frame 110.

[0039] It should be noted that the controller 280 can be a common Siemens SMART 200 PLC, controlling the first servo motor 140 and the second servo motor 260 of the unloading trolley. The unloading impeller 250 uses an ABB ACS-550 frequency converter for speed regulation. The position sensor uses a YW-630 IC card reader with RS485 communication to read and write IC cards spaced one meter apart to determine the position information of the unloading trolley. The wireless communication relay AB433L is connected to the SMART 200 PLC Ethernet port. The specific combination can be adjusted and selected according to the actual situation and installed in some empty spaces on the frame 110. The specific wiring connection and principle are well known to those in the field and will not be described in detail here.

[0040] The adjusting component 210 includes a bidirectional lead screw 211 and a moving block 212. The bidirectional lead screw 211 is rotatably mounted inside the frame 110, and the moving block 212 is threadedly connected to the bidirectional lead screw 211. The connecting plate 220 is fixedly connected to the moving block 212. By setting the bidirectional lead screw 211 and the moving block 212, the operator rotates the bidirectional lead screw 211, which drives the moving block 212 to move through the thread transmission principle. The moving block 212 then drives the connecting plate 220 to move.

[0041] Specifically, a guide block 112 is provided on the top of the frame 110, and the connecting plate 220 is slidably connected to the guide block 112. The guide block 112 is T-shaped. By setting the T-shaped guide block 112, the connecting plate 220 is supported to slide stably in a straight line.

[0042] Specifically, the connecting plate 220 has a sliding groove 221, which is adapted to the guide block 112. By setting the sliding groove 221 and the T-shaped guide block 112 to slide together, the connecting plate 220 is restricted from rotating and the connecting plate 220 is restricted from flipping up.

[0043] In one specific implementation, a handwheel 213 is fixedly sleeved on the bidirectional lead screw 211, and a scale line is provided on the top of the frame 110 corresponding to the end of the connecting plate 220. By providing the handwheel 213, it is convenient to rotate the handwheel 213 to drive the bidirectional lead screw 211 to rotate, which is convenient for personnel to operate.

[0044] In this embodiment, a threaded post 231 is provided at the bottom of the carriage 230. The threaded post 231 passes through the connecting plate 220 and is threaded with a nut. By providing the threaded post 231, when assembling the carriage 230, the threaded post 231 is passed through the hole on the connecting plate 220 and then tightened with a nut.

[0045] In this embodiment, a reinforcing rib 232 is provided on the outside of the carriage 230, and the carriage 230 is in the shape of an inverted trapezoid. By providing the reinforcing rib 232, it is beneficial to strengthen the structural strength of the carriage 230.

[0046] It should be noted that the inner wall of the unloading cylinder 240 is arranged at an inclination, and the inclination of the inner wall of the unloading cylinder 240 is directed towards the unloading cylinder 240. By setting the inner wall of the unloading cylinder 240 to be inclined towards the unloading cylinder 240, it is beneficial for the coal to fall out of the unloading cylinder 240. Furthermore, the design of multiple blades on the unloading impeller 250 inside the unloading cylinder 240 allows it to block the coal when it is not rotating, and only when it is rotating will it drive the coal to be unloaded.

[0047] The working principle of this mobile coal conveying and unloading trolley is as follows: When the first servo motor 140 is turned on, it drives the drive gear 151 to rotate. The drive gear 151 meshes with and drives the driven gear 152 to rotate. The driven gear 152 drives the rotating rod 120 to rotate, and the rotating rod 120 drives the track wheel 130 to move. When it moves to the unloading position, the second servo motor 260 is started to drive the unloading cylinder 240 to rotate, so that the coal is evenly unloaded from the bottom unloading cylinder 240. This process is stable and safe. Furthermore, for multiple... For trolleys damaged in different locations, the threaded post 231 can be passed through the hole on the connecting plate 220 by assembling the carriage 230, and then tightened with a nut for assembly and use, which greatly saves costs. At the same time, turning the handwheel 213 drives the double-sided lead screw 211 to rotate. The double-sided lead screw 211 drives the moving block 212 to move through the thread transmission principle. The moving block 212 drives the connecting plate 220 to adjust the distance between the two connecting plates 220, which can adapt to the assembly and use of carriages 230 of various specifications and sizes, greatly improving practicality.

[0048] It should be noted that the specific models and specifications of the first servo motor 140, the second servo motor 260, and the controller 280 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0049] The power supply and operating principle of the first servo motor 140, the second servo motor 260, and the controller 280 are clear to those skilled in the art and will not be described in detail here.

[0050] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
