Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of shield tunnel muck treatment construction, and particularly relates to a hydraulic control automatic separation device for muck of a transport vehicle. Background Technique
[0002] The shield tunneling method is a commonly used construction method for subway tunnel construction at present. During shield tunneling, muck slurry is inevitably generated. When carrying out the process of shield slurry pressure filtration treatment and transportation, the traditional method generally uses an excavator to directly turn over, or combines the size of the muck pond and the fluidity of the slurry, and uses a rail transport vehicle to transport the shield slurry, avoiding the problems of repeated construction, low efficiency, high fuel cost, etc. caused by the multiple turnovers of the excavator.
[0003] However, when using the above method, due to the generally small volume of the slurry transport trolley under the condition of a short distance, and its high transfer efficiency requirement, the traditional muck transport vehicle generally uses a tipping bucket to lift and unload soil or uses a crane to unload soil. The unloading process has problems such as cumbersome steps, slow work efficiency, and high additional costs, which has a great impact on the entire muck slurry transfer construction process. Therefore, how to improve the unloading efficiency of the muck transport vehicle and reduce the unloading construction steps are the problems that need to be solved and optimized at present. Content of the Utility Model
[0004] The purpose of the utility model is to provide a hydraulic control automatic separation device for muck of a transport vehicle, which is used to be installed on the muck transport vehicle to realize automatic separation and unloading of shield slurry. By using a hydraulic device to lift the slurry flow rate control blade in the muck transport vehicle and adjusting the gap between the control blade and the inner wall of the muck vehicle, the slurry unloading rate is adjusted, so as to improve the construction efficiency of shield slurry transfer and reduce the construction cost.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A hydraulic control automatic separation device for muck of a transport vehicle, the transport vehicle muck automatic separation device has two hydraulic jacks installed at the end of the muck vehicle; the telescopic direction of the hydraulic jacks is arranged downward, and the hydraulic jacks are fixed with bolt-fastened steel plates; a piston cross bar is arranged at the top of the piston rods of the two hydraulic jacks, and the hydraulic jacks are connected with the control blade through steel wires and fixed pulleys, forming a structure in which the control blade moves synchronously with the telescopic movement of the hydraulic jacks; the transport vehicle muck automatic separation device is also provided with an auxiliary fixing mechanism; the auxiliary fixing mechanism has a longitudinal beam for placing the fixed pulley therein; both ends of the longitudinal beam are fixed on the muck vehicle, and the middle part thereof is connected with the cross beam. Each cross beam is fixed by two of the I-shaped steel columns, and an isolation steel plate is arranged in the middle of the muck vehicle to serve as a cross beam column, dividing the control blade into two independently lifted parts, avoiding the difficulty in lifting caused by the overlong control blade.
[0007] The described control blade is welded into an "angle shape" by two steel plates and reinforced by welding with one steel plate. A hole is reserved at the top corner of the control blade for connecting the control blade with the steel wire rope, enabling the up and down movement of the control blade through the contraction of the steel wire rope.
[0008] The described longitudinal beam is welded by two long steel plates.
[0009] A hydraulic control transport vehicle muck automatic separation device proposed by the present utility model adopts the above technical solutions and has the following beneficial effects:
[0010] Firstly, the soil unloading process is simple and the soil unloading rate can be controlled: after the muck truck runs to the soil unloading position, only by controlling the hydraulic switch, the movement of the control blade can be realized through the hydraulic jack, realizing the automatic falling of the muck slurry. At the same time, the moving distance of the control blade can be independently selected to control the falling rate of the slurry, realizing fast, continuous and stable soil unloading operations and improving the soil unloading efficiency.
[0011] Secondly, the structure is simple and the installation is convenient: except for the hydraulic jack, the device is of a pure mechanical structure. The raw materials of each structure are common construction materials on site, and the basic components of the device can be formed through simple processing. The structural composition unit is simple, the failure rate is low, and the maintenance is convenient.
[0012] Thirdly, it is environmentally friendly, energy-saving and has strong applicability: adopting advanced hydraulic transmission technology and a force transmission device composed of a steel wire rope + pulley combination, it avoids the energy consumption of traditional high-power tipping soil unloading and hoisting soil unloading, effectively reducing energy consumption and emissions, and can adjust the device size by itself, and can adapt to and be installed on various muck truck structures.

[0019] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.
[0020] As Figures 1 to 5 shown, a hydraulic control transport vehicle muck automatic separation device is used to be installed on a shield muck transport trolley to realize the function of rapid automatic unloading of muck slurry. The transport vehicle muck automatic separation device consists of a hydraulic jack 1 installed at the end of the transport vehicle, a muck flow rate control vane 9 installed inside the muck truck, and devices such as a steel wire rope 5 and a fixed pulley 6 connecting the hydraulic jack 1 and the control vane 9.
[0021] The hydraulic jack includes components such as a hydraulic jack cylinder 1, a fixed steel plate 2, a piston rod 3, a piston crossbar 4, a hydraulic pump 7, and a hydraulic oil pipe 8. During installation, first fix the bottoms of the two hydraulic jack cylinders 1 on the outside of the end of the muck truck, arrange the telescopic direction downward, and fix the cylinders with the fixed steel plate 2. Connect the piston crossbar 4 to the tops of the two piston rods 3 to ensure that it can move synchronously with the piston rod. And install the hydraulic pump 7 beside it, and connect the hydraulic pump and the hydraulic jack cylinder with the hydraulic oil pipe 8 to provide power for it to perform telescopic jacking operations.
[0022] The muck flow rate control vane is an important component for controlling the automatic separation of slurry, mainly composed of a control vane 9, a steel wire rope 5 connecting the hydraulic jack and the control vane, a fixed pulley 6, and an installation auxiliary fixing structure, etc. During installation, first install an isolation steel plate 11 at the middle position inside the muck truck, which mainly divides the control vane into two pieces to avoid difficulties in lifting during the control vane process. Secondly, install I-beam columns 10 on both its left and right sides, and install a cross beam 12 on them to form the main stress structure for lifting the control vane. Then install a fixed longitudinal beam 13 on the cross beam. The longitudinal beam 13 is composed of two long steel plates and a channel steel cover. The two long steel plates are arranged longitudinally, with both ends leaning against the end of the muck truck and the middle leaning against the cross beam, and are welded and fixed; the two steel plates are spaced a certain distance horizontally to ensure that a fixed pulley 6 can be installed in the middle. The fixed pulley is installed and fixed by drilling holes at the designed position on the longitudinal beam. One end of the steel wire rope 5 is connected to the control vane, and after the steel wire rope passes around the fixed pulley, it is connected to the piston cross bar, so that the piston movement of the hydraulic jack drives the steel wire rope to change the direction of force through the fixed pulley and makes the control vane move up and down, thereby realizing the automatic separation of shield slurry. Finally, to prevent the slurry from invading the inside of the longitudinal beam during slurry loading and causing the steel wire rope to be blocked, a channel steel cover is installed above the longitudinal beam to buckle the two steel plates, isolating the path for the slurry to enter the inside of the longitudinal beam and preventing the steel wire rope from being contaminated and reducing its service life.
[0023] When the hydraulic control muck automatic separation device of this embodiment is in use, during the process of loading shield slurry, the hydraulic jack is closed, and the piston rod 3 is in a contracted state. At this time, due to its own gravity, the control vane 9 will fall and lean against the inner wall of the muck truck. At the same time, the slurry loaded into the muck truck will also firmly press the control vane 9 due to gravity, making the control vane contact the inner wall of the muck truck more tightly and preventing slurry leakage during transportation. After the muck truck is loaded and transported to the soil unloading position, at this time, since the control vane has been firmly pressed at the bottom by the slurry and the slurry cannot be separated independently, the hydraulic jack is started at this time to make the piston rod 3 perform an elongation operation. The steel wire rope is driven to move downward through the piston cross bar. After the steel wire rope changes direction through the fixed pulley, it drives the control vane to move slowly upward. At this time, a gap will slowly appear between the control vane and the inner wall of the muck truck, and the slurry will fall downward automatically under the action of gravity through the gap, realizing the automatic soil unloading process. During the soil unloading process, the elongation distance of the piston rod of the hydraulic jack can be controlled, and then the gap between the control vane and the inner wall of the muck truck can be adjusted, so that the rate of automatic soil unloading of the slurry can be controlled, effectively improving the transfer efficiency of shield slurry. At the same time, by adjusting the gap between the control vane and the inner wall of the muck truck, it is also applicable to other types of muck. When the muck particle size is larger, just adjust the gap between the control vane and the inner wall of the muck truck to be larger, greatly enhancing the practicability of the entire device.
[0024] 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.
