Description
Technical Field
[0001] The invention belongs to the technical field of shield tunnel slag treatment construction, and in particular relates to a shield slag transport vehicle for short-distance transportation. Background Art
[0002] When tunneling, the shield machine uses the friction between the cutter head and the soil to crush the soil in front of the tunnel and realize the tunnel excavation process. In order to reuse the shield slag mud, the newly excavated mud is usually temporarily piled in the slag pit, and then the mud is transported out of the slag pit for mud treatment. In order to ensure that the mud can be transported out conveniently and quickly, the mud extraction equipment is usually installed in a fixed position on one side of the slag pit, so the mud needs to be rushed from other positions in the slag pit to the installation position of the mud extraction equipment for easy loading and transportation. Since excavators and other equipment cannot directly turn over the shield mud inside the slag pit, an operating platform needs to be set up for the slag turning equipment to operate, and the shield mud has strong fluidity and needs to be turned over multiple times.
[0003] However, the above method requires the use of an excavator to repeatedly flip the mud from other locations to the designated location, and the amount of each transfer is relatively small, resulting in a large number of repeated construction operations, low efficiency, high fuel costs for mechanical equipment, and serious environmental pollution. Therefore, in order to avoid the above problems, it is necessary to develop a transport vehicle for transporting slag in the slag pit, and use the transport vehicle to transfer the mud from one end of the slag pit to the other end over a short distance, thereby reducing the repetitive work of multiple flips of the excavator and improving the efficiency of mud transportation. Summary of the invention
[0004] The purpose of the present invention is to propose a shield slag transport vehicle for short-distance transportation, which is used to be installed on an operating platform inside a slag pool to transport mud; at that time, the excavator only needs to load the mud onto the slag transport vehicle at the end, and the vehicle automatically transports the mud to a designated position for unloading according to the installed track, and can realize functions such as autonomous selection of the transport vehicle's parking position and automatic unloading of the mud, thereby avoiding multiple reverse transportation of the excavator, thereby improving the transportation efficiency of the shield slag and reducing the overall construction cost investment.
[0005] To achieve the above object, the present invention provides the following technical solutions: A shield-bored slag transport vehicle for short-distance transportation, the shield-bored slag transport vehicle having a trolley frame; the trolley frame is formed by connecting two main longitudinal beams and four enclosure steel plates installed between the main longitudinal beams, and presents an inverted trapezoidal structure, and the inner cavity of the inverted trapezoidal structure trolley frame constitutes the loading space of the transport vehicle; when the enclosure steel plates are connected, the bottom of the inverted trapezoid is not completely closed, leaving a gap of 500mm, so that the slag slurry can flow out of the gap; a traveling leg is arranged below the end of the main longitudinal beam, and the traveling wheel is arranged on the traveling leg to support the transport vehicle to move forward and backward; shield-bored slag transport vehicle The vehicle is also provided with a lifting and unloading supporting device; the lifting and unloading supporting device has a control blade in the shape of a "human"; the control blade is located in the loading space of the transport vehicle; the control blade is connected to one end of the wire rope; the other end of the wire rope is connected to the hydraulic jack; the wire rope is wound on the pulley block, and the pulley block is used to change the force direction of the wire rope, so that the control blade moves up and down, so that the gap at the bottom of the transport vehicle is closed by the up and down movement of the control blade, and the unloading operation of the slag mud is completed; the loading space of the transport vehicle is also provided with a lifting and unloading supporting device; the lifting and unloading supporting device has a control blade in the shape of a "human"; the control blade is located in the loading space of the transport vehicle; the control blade is connected to one end of the wire rope; the other end of the wire rope is connected to the hydraulic jack; the wire rope is wound on the pulley block, and the force direction of the wire rope is changed by the pulley block, so that the control blade moves up and down, so that the gap at the bottom of the transport vehicle is closed by the up and down movement of the control blade, and the unloading operation of the slag mud is completed; Isolation steel plate columns are provided; the isolation steel plate columns divide the loading space of the transport vehicle into two parts connected at the bottom, ensuring that the mud in the transport vehicle can be stored in a warehouse, and play a role in supporting the vertical force of the pulley block on the transverse and longitudinal beams, wherein the isolation steel plate in the middle part divides the control blade into two pieces, and the control blade is disconnected here to avoid the control blade being too long and causing difficulty in lifting; a driving device is installed on the traveling leg; there are two driving devices; the wheels of the driving device are installed at the bottom of the traveling leg, a signal processor is installed on the driving device, and a movable A detachable signal blocker; the detachable signal blocker comprises a touch sensor and a blocking piece. When the transport vehicle is running, the touch sensor on the driving device and the blocking piece on the detachable blocker have a "collision" effect. The signal processor is used to process the "collision" signal, and an instruction is issued to stop the driving device of the transport vehicle, so as to realize the docking command of the transport vehicle. The signal is used to issue a control instruction to the hydraulic jack, so that the jack starts working, drives the control blade to lift upward, and leaks out of the gap at the bottom of the transport vehicle, so as to realize the automatic unloading process of the slag mud from the gap. The shield-bored muck transport vehicle is also provided with an operating platform.
[0006] A support is added to each of the two side ends of the trolley frame, one end of which is connected to the back rib of the surrounding steel plate and the other end is connected to the driving support leg to form a triangular stable structure.
[0007] The enclosure steel plate is provided with back-ribbed channel steel to enhance the bearing capacity of the steel plate.
[0008] The operating platform includes lattice columns and rail steel plates and flat steel plates installed on the lattice columns; the operating platform is installed inside the slag pit to provide a platform for transport vehicles and excavators to operate. Two lattice columns with the same spacing and horizontal arrangement as the operating platform are used as the operating platform. The bottom is fixed with columns and diagonal braces to bear the loads generated by various operations on the operating platform. The lattice column size is 460mm×460mm, and it is composed of four 180×18 angle steels welded and connected with a welded steel web in the middle.
[0009] The track steel plate and the flattened steel plate are both installed on the operating platform. The track steel plate is installed in the middle position of the operating platform with a spacing equal to the wheel spacing of the transport vehicle. At the same time, in combination with the wheel rims of the transport vehicle, a certain gap needs to be reserved on both sides of the track steel plate to facilitate the smooth passage of the wheels of the transport vehicle on the track steel plate. Then, the flattened steel plate is fully spread outside the gap to make the flattened steel plate and the track steel plate have the same elevation, so that the excavator can move freely on the operating platform without damaging the vehicle track.
[0010] The shield-driven slag transport vehicle for short-distance transportation proposed by the present invention adopts the above technical solution and has the following beneficial effects: First, by using rail steel plates and flat steel plates, it is ensured that the transport vehicle can run on the rail steel plates on the operating platform without affecting the operation of the excavator on the operating platform, thereby realizing the joint operation of the excavator and the transport vehicle.
[0011] Secondly, by using transport vehicles, the mud in the slag pool can be quickly transferred, and a large amount of mud can be directly transported to the designated location at one time, avoiding the problems of long construction period, large fuel consumption, high environmental pollution, etc. caused by using excavators to turn over the mud multiple times. It effectively reduces energy consumption and emissions, and has environmental protection and energy-saving effects.
[0012] Third, the transport vehicle has a high degree of automation. During the operation of the transport vehicle, the contact piece automatically touches the blocking piece, thereby transmitting a signal to the drive system to stop the vehicle within a short distance, and the parking position is accurate. At the same time, the jack can be controlled to lift the control blade according to the stop signal to leak out the gap at the bottom of the transport vehicle, realizing the automatic unloading of the slag and mud in the transport vehicle.
[0013] Fourthly, the construction efficiency is high and the additional investment is reduced. The transport capacity of the transport vehicle can reach 12m³ at a time, which is a significant improvement compared to the excavator flip. In addition, the use of automatic start-stop and unloading devices avoids manual control, reduces personnel investment, and greatly improves transportation time and unloading efficiency.
[0014] Fifth, due to the detachability of the blocking device, the installation position of the blocking device can be adjusted according to the on-site construction conditions, and the parking position of the transport vehicle can be selected independently without affecting other operations on the operating platform.
[0015] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention.

DETAILED DESCRIPTION
[0017] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The various details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner, and the following embodiments and features in the embodiments can be combined with each other without conflict.
[0018] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on the present invention. In order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of actual products. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.
[0019] like Figures 1 to 8 The shield-bored muck transport vehicle shown is used for short-distance transportation, and is used to quickly transport the mud around the muck pool to a designated location, and includes a trolley frame 1, a fixed operating platform 4, a lifting and unloading supporting device 2 installed inside and on the top of the trolley frame 1, and a walking supporting device 3 installed at the end of the trolley frame 1 and above the operating platform.
[0020] Reference Figure 2 and Figure 6 The operating platform 4 is mainly composed of lattice columns 43. The lattice columns 43 are used to build the operating platform 4 in the slag pool, which is convenient for the slag transport vehicle and the excavator to operate on the operating platform; a track steel plate 41 and a flat steel plate 42 are arranged on the top surface of the operating platform 4. The track steel plate 41 is installed in the middle position of the lattice column 43 and is the travel track of the transport vehicle. The flat steel plate 42 is installed on both sides of the track steel plate 41 and leaves a certain gap with the track steel plate 41 so that the wheels of the transport vehicle can pass normally; the flat steel plate 42 should be fully paved on the lattice column 43 except the track steel plate 41 and the corresponding gap, and the installation elevation of the flat steel plate 42 should be the same as the elevation of the track steel plate 41, so as to provide a flat surface, so that the slag loading machinery (such as an excavator) can operate normally on the operating platform 4 without damaging the track steel plate 43, so that the excavator and the transport vehicle can work at the same time, and the slag transportation efficiency is improved.
[0021] Reference Figure 2 and Figure 4 The transport vehicle trolley frame 1 is composed of two main longitudinal beams 11, four protective steel plates 12 installed around the main longitudinal beams 11, driving legs 13 installed below the two ends of the main longitudinal beams 11, and transverse supports 14 connecting the driving legs 13 and the protective steel plates 12, which are used to strengthen the overall structural stability of the trolley frame 1; the protective steel plates 12 are provided with back-ribbed channel steel to improve their bearing capacity. When installed, the four protective steel plates 12 are inverted trapezoidal structure. When the two longitudinal protective steel plates 12 are spliced, a gap of about 500 mm is left at the bottom to facilitate the subsequent slag mud to automatically fall through the gap to realize the soil unloading function.
[0022] Reference Figure 4The transport vehicle is provided with two hydraulic jacks 21 for lifting and unloading supporting devices 2, which are installed at the end of the transport vehicle and arranged downward. The two hydraulic jacks 21 are connected at the top with a piston cross bar 22 so that they can perform synchronous reciprocating operations; a steel wire rope 23 is connected to the piston cross bar, and a pulley 24 is arranged on the top of the transport vehicle. The steel wire rope 23 passes through the pulley 24 and enters the interior of the transport vehicle to connect with the control blade 25.
[0023] Reference Figure 5 and Figure 7 A total of five pulleys 24 are arranged on the top of the transport vehicle, and the pulleys 24 are installed on the transverse and longitudinal beams 27. The wire ropes 23 are connected to the control blades 25 arranged inside the transport vehicle through the pulleys 24. The control blades 24 are in the shape of a "human" and are welded from three steel plates. The wire ropes 23 are driven by the jack 21 to change direction through the pulleys 24, so that the control blades 25 move up and down, realizing the opening and closing of the bottom gap, so that the slag mud can automatically pass through the gap under the action of gravity to unload the soil; the two ends of the transverse and longitudinal beams 27 are connected to the main longitudinal beams 27. The beam 11 is supported by an isolation steel plate column 26 in the middle. A wide steel plate is used as a support for the middle beam to separate the control blade 25 into two parts to prevent the control blade from being too long and causing difficulty in lifting. It also plays a role in isolating the internal space, but it is not completely isolated, so that the shield mud can be stored in the transport vehicle. The other two beams use two narrow steel plates as isolation steel plate columns 26, leaving a middle position to facilitate the control blade to move up and down to open and close the bottom gap, thereby realizing the function of autonomous unloading of slag mud.
[0024] Reference Figure 4 The supporting device 3 of the transport vehicle travel is installed on the transport vehicle and the operating platform, the wheel 34 is installed on the driving leg 13 of the transport vehicle, the driving device 31 is connected to the wheel 34, and can control the operation and stop of the wheel 34. A touch sensor 33 and a signal processor 32 are arranged on the driving device 31. The sensor 33 is responsible for receiving the signal and transmitting it to the signal processor 34. After receiving the signal, the signal processor 32 converts the signal into a control instruction in a very short time, controls the driving device 31 to stop the wheel 34, and realizes the automatic stop function of the transport vehicle.
[0025] Reference Figure 6The blocking device in the supporting device 3 for the traveling of the transport vehicle is installed on the operating platform 1. The upper and lower fixing steel plates 36 are clamped on the operating platform by fixing bolts 35. There are reserved holes at the corresponding positions of the upper and lower fixing steel plates 36, which are convenient for the fixing bolts 35 to pass through and fix; a blocking piece 37 is welded on the side of the fixing steel plate 36. During installation, ensure that the blocking piece 37 and the touch sensor 33 are in a straight line, and ensure that the touch sensor 33 of the transport vehicle can "collide" with the blocking piece 37 during transportation, thereby triggering the sensor 33 to transmit a signal and controlling the transport vehicle to stop running. In addition, the blocking device adopts a detachable design, and the installation position can be adjusted at any time according to the construction situation. It only needs to loosen the fixing bolts 35 and reinstall it at the designated position. It has the characteristics of strong adaptability and high transportation efficiency.
[0026] Before the shield-bored muck transport vehicle for short-distance transportation is put into operation, the track steel plate 41 and the flattened steel plate 42 are first installed on the operating platform, so that the transport vehicle and the excavator equipment can work on the operating platform, and the blocking device is installed at the muck unloading and loading position, so that the blocking piece 37 is just on the path of the touch sensor 33. After the transport vehicle is processed, the signal processor 32 is connected with the hydraulic jack 21 and the drive device 31, and a control code is implanted in advance. When the touch sensor 33 collides with the blocking piece 37 during the operation of the transport vehicle, after the signal processor 32 receives the "collision" signal, it sends instructions to the drive device 31 and the hydraulic jack 21 respectively, so that the transport vehicle stops and lifts the control blade 25, and the muck is automatically unloaded synchronously. At the same time, the transportation stop time interval is set according to the loading and unloading time, so that the transport vehicle automatically runs in the opposite direction after stopping for a certain period of time, until the touch sensor 33 and the blocking piece 37 meet at the other end, triggering the stop instruction and the control blade lifting or lowering instruction, and completing a working cycle of the muck transport vehicle.
[0027] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the present invention.
