Description

Technical Field

[0001] The utility model belongs to the technical field of shield tunnel slag processing construction, and in particular relates to an automatic start-stop control device for a rail slag transport vehicle. Background Art

[0002] The mud generated during shield tunneling construction is inevitable, and it is usually temporarily piled in a slag pit. When the shield slag is subsequently transferred and processed, the mud needs to be moved from one end of the slag pit to the other end for easy loading and transportation. To ensure a smooth flipping process, an operating platform is built with steel, and tracks are built on the operating platform. A slag truck is installed, and the slag truck is used to quickly transfer the mud, avoiding the problems of low construction efficiency and high fuel and power costs caused by multiple flips of the excavator.

[0003] Due to the limited space on the operating platform, the short transfer distance of the muck transport truck and the high efficiency of soil unloading, the start and stop of the trolley need to be controlled at all times, and the parking position accuracy is required to be high. It is difficult to ensure the accuracy of the parking position of the trolley by manual control, and long-term operation is prone to fatigue and cause unnecessary accidents. Therefore, how to improve the parking accuracy of the muck transport truck and realize automatic start and stop to free up the control personnel is a problem that needs to be solved and optimized at present. Utility Model Content

[0004] The utility model aims to propose an automatic start-stop control device for a rail muck transport vehicle, which is used to be installed on the muck transport vehicle to realize the automatic start-stop of the vehicle at a precise position. By installing a touch-type sensor system and a detachable blocking mechanism, the drive system program is adjusted so that the sensor is braked and started within a specified time after being hit, thereby realizing the automatic start-stop function of the muck vehicle, and the installation position of the detachable blocking mechanism can be independently selected to change the parking position of the transport vehicle, thereby improving the shield mud transfer construction efficiency and reducing personnel operation costs.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An automatic start-stop control device for an orbital muck transport vehicle. The automatic start-stop control device has a touch sensing system installed on the trolley and a detachable blocking mechanism installed on the traveling track. The touch sensing system has touch plates and signal receivers installed at both ends of the transport vehicle. The detachable blocking mechanism consists of a blocking plate, an upper fixed steel plate, a lower fixed steel plate, and bolts. The upper fixed steel plate is placed on the traveling track, and the lower fixed steel plate is placed under the operation platform. A blocking plate for "colliding" with the touch plate is welded on the outer side of the upper fixed steel plate. The signal receiver is used to transmit the received "collision" information to the information processor for further processing to control the automatic start and stop of the orbital muck transport vehicle. Using the short signal generated by the collision between the touch plate and the blocking plate, the movement of the trolley is controlled, and by adjusting the position of the obstacle, the trolley can start and stop at a precise position.

[0007] The traveling track is installed on the operation platform.

[0008] An automatic start-stop control device for an orbital muck transport vehicle proposed by the present utility model, adopting the above technical solutions, has the following beneficial effects:

[0009] First, the parking position can be accurately controlled: Before operation, the detachable obstacle is fixed at the position to be docked. During the operation of the trolley, the touch plate touches the blocking plate automatically, thereby transmitting a signal to make the drive system stop the trolley within a short distance. The docking position is accurate, avoiding the problems of too many transfer times caused by premature docking and collision and derailment accidents caused by too late docking.

[0010] Second, reduce manual input and the docking position can be determined independently: Through the automatic docking and starting of the trolley, it avoids the need for manual operation at any time, reduces the personnel input, and at the same time ensures the stable operation. At the same time, due to the detachable nature of the blocking plate, the installation position of the blocking plate can be adjusted at any time, and the docking position of the trolley can be selected independently without affecting other operations on the operation platform.

Detailed implementation mode

[0015] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0016] As Figures 1 to 3 An automatic start-stop control device for a track muck transport vehicle as shown is used to be installed on a shield muck transport trolley and its track to realize the automatic start-stop function of the muck transport vehicle. The automatic start-stop device of the transport vehicle consists of a touch sensing system installed on the outer side of the end of the transport vehicle and a detachable blocking mechanism installed on the forward track.

[0017] The touch sensing system includes devices such as a touch piece 1, a signal receiver 2, a signal transmission line 4, a signal processor 5, and a drive system 6. During installation, first connect the touch piece 1 and the signal receiver 2 together and connect them as a whole to the fixed steel plate 3, and fix them together on the outer sides of both ends of the transport vehicle, and make the touch piece extend out of the fixed steel plate for easy collision with the blocking piece. The signal processor 5 is installed on the drive system 6 of the transport vehicle and transmits signals with the signal receiver 2 through the signal transmission line 4, processes the received signals, and issues control instructions within a short time, so that the drive system 6 brakes the wheels 7 of the transport vehicle, causing the transport vehicle to have a frictional effect with the track steel plate 8 to ensure braking within a short distance and complete the docking operation at a precise position.

[0018] The detachable blocking mechanism is an important component for controlling the transport vehicle to stop at a designated position, and includes an upper fixed steel plate 10, a lower fixed steel plate 9, bolts 11, a blocking piece 12 and other devices. During installation, the size of the upper and lower fixed steel plates is first determined according to the size of the working platform, and holes are reserved at the corresponding positions for easy later fixation; secondly, the upper and lower fixed steel plates are placed on the upper and lower sides of the working platform respectively, and the bolts 11 are passed through the reserved holes, and the bolts are tightened to clamp the upper and lower fixed steel plates firmly on the working platform, thereby fixing the upper fixed steel plate 10 on the track working platform where the transport vehicle is moving. Finally, a blocking piece 12 is welded near the end position of the upper fixed steel plate 10 and at the position corresponding to the touch piece 1. The blocking piece is made of steel plate so that the blocking piece and the touch piece are on the same straight line, ensuring that the touch piece can "collide" with the blocking piece during the operation of the transport vehicle, thereby transmitting the docking information. At the same time, due to its detachable design, the installation position of the detachable blocking mechanism can be adjusted at any time according to the mud distribution in the slag pit and the operation conditions of the excavator on the operating platform, so that the transport vehicle can be docked at the designated location.

[0019] When the automatic start-stop control device of a rail muck transport vehicle of this embodiment is used, before the shield mud is transported, a detachable blocking mechanism is first installed at the position of loading and unloading the mud, and the parking position during loading and unloading is determined. Then the touch sensor system is installed on the transport vehicle, and during installation, it is ensured that the touch piece 1 and the blocking piece 12 are in a straight line, and can collide and transmit signals. The control code is implanted in the signal processor 5 and the drive system 6. When the touch piece 1 and the blocking piece 12 "collide", the signal receiver 2 senses the touch signal and transmits the signal to the signal processor 5. After receiving the signal, the signal processor 5 triggers the control code and issues a transport vehicle parking instruction. After receiving the parking instruction, the drive system responds in a very short time, quickly reduces the speed of the drive system, increases the friction between the wheel 7 and the rail steel plate 8, and controls the vehicle to dock. The entire process from "collision" to docking is extremely short, and all the above work can be completed within 0.5s, and the docking accuracy can reach millimeter level. At the same time, a control code can be implanted in the drive system in advance. The command of the control code is to automatically start the transport vehicle after receiving the "collision" signal and wait for the transport vehicle to stop after a specified time, and move in the opposite direction until the touch piece 1 touches the blocking piece 12 on the other side and then stops, thereby realizing the automatic round-trip operation and automatic start-stop function of the transport vehicle. The stop time interval can be determined comprehensively according to the site conditions, the unloading rate of the slag mud, the loading rate, etc., and the stop time can be adjusted at any time according to the site construction conditions, which improves the applicability and practicality of the whole device.

[0020] The above disclosure is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
