Description

Technical Field

[0001] The utility model belongs to the technical field of municipal emergency equipment, in particular to a municipal drainage vehicle. Background Art

[0002] In the field of municipal management and emergency rescue in modern cities, an effective drainage system is an important factor in ensuring urban safety and reducing the impact of natural disasters. However, with the accelerated development of urbanization, municipal emergency rescue drainage faces various challenges, such as the aging of drainage systems, the frequent occurrence of extreme weather, the increase in urban waterlogging points, and the slow response speed of traditional drainage equipment. These difficulties make it difficult for urban drainage systems to deal with large amounts of accumulated water in a timely and effective manner when extreme weather such as rainstorms and floods occurs, thus causing serious waterlogging disasters, bringing great inconvenience to the lives of citizens, and even causing property and life losses. In the face of such disasters, an efficient and flexible solution is urgently needed. The municipal drainage vehicle came into being. It carries a drainage pump for mobility, can quickly respond to waterlogging situations, and achieve efficient drainage.

[0003] At present, the drainage vehicles on the market are mainly divided into electric pump drainage vehicles and hydraulically driven drainage vehicles. The electric pump is powered by the mother vehicle and is manually carried to the waterlogging point for drainage. The electric pump that can be carried manually generally has a small displacement and is driven by a high-voltage permanent magnet motor, which poses a risk of leakage. The hydraulically driven drainage vehicle is powered by the mother vehicle to drive the sub-vehicle to carry the water pump into the waterlogging point, and the water pump is driven by the hydraulic pump to perform drainage operations. Due to the long continuous operation time of emergency drainage, the heat dissipation effect of the hydraulically driven drainage vehicle is poor, and the long-term working stability is insufficient. The hydraulically driven drainage pump is large in size, heavy in weight, and inconvenient to replace. The hydraulic pump models of the drainage vehicles on the market are currently single, and it is impossible to quickly switch between large flow and high lift according to drainage requirements. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the heat dissipation effect of the hydraulic system of the hydraulically driven drainage vehicle is poor, and the water pump is configured in a single manner and is inconvenient to replace.

[0005] In order to solve the above technical problems, the specific technical solutions of the utility model are as follows:

[0006] A municipal drainage vehicle comprises a crawler chassis 1, a swing frame 2, a swing cylinder 3, a rocker arm 4, a guide rail 5, a lifting support 6, a lifting cylinder 7, a radiator 8, a lifting frame 9, a fastener strap 10, a drainage pump assembly 11, a hydraulic system 12, and a control box 13;

[0007] A lifting support 6 is arranged above the crawler chassis 1; the pipelines and control box 13 of the hydraulic system 12 are arranged above the crawler chassis 1; the radiator 8 is installed at the front end of the crawler chassis 1; two parallel vertical guide rails 5 are arranged above the crawler chassis 1;

[0008] One end of the lifting cylinder 7 is connected to the lifting support 6, and the other end is connected to the lifting frame 9;

[0009] The lifting frame 9 is a U-shaped structure, with slider structures provided on both sides thereof, and the slider structures are slidably matched with the corresponding guide rails 5;

[0010] The swing frame 2 is an L-shaped structure, and a fastener strap 10 is provided at its upper end. The drainage pump assembly 11 is placed on the swing frame 2 and fixed by the fastener strap 10. The swing frame 2 is hinged to the lifting frame 9 as a whole by a pin shaft.

[0011] A rocker arm is arranged on the side of the swing frame 2; one end of the swing cylinder 3 is hinged to the rocker arm, and the other end is hinged to the lifting frame 9.

[0012] The crawler chassis includes left and right crawlers and a crossbeam in between.

[0013] The interior of the radiator is a hollow cavity structure, and heat dissipation fins are arranged on the outside of the cavity.

[0014] Among them, two pin shafts are protruding from both sides above the swing frame and are respectively hinged to the corresponding lifting frame slider structure.

[0015] The utility model has the following advantages: the hydraulic system is cooled by water flow through the radiator at the front end, which greatly improves the heat dissipation efficiency and improves the stability of the drainage system operation; compared with the current municipal drainage vehicles, the drainage pump body is more adaptable and the water pump can be flexibly replaced according to drainage needs, thereby improving rescue efficiency.

DETAILED DESCRIPTION

[0022] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-Figure 5 As shown, the municipal drainage vehicle provided in this embodiment includes a crawler chassis 1, a swing frame 2, a swing cylinder 3, a rocker arm 4, a guide rail 5, a lifting support 6, a lifting cylinder 7, a radiator 8, a lifting frame 9, a tie-down strap 10, a drainage pump assembly 11, a hydraulic system 12, and a control box 13.

[0024] in:

[0025] The crawler chassis 1 is used to install the guide rail 5, the lifting support 6, the radiator 7, the hydraulic system 12 and the controller 13;

[0026] The swing frame 2 is hinged on the slider of the lifting frame 9 and connected to the lifting frame 9 through the swing cylinder 3;

[0027] The rocker arm 4 is fixed to the left side of the swing frame 2 and connected to the piston rod of the swing cylinder 3;

[0028] The guide rail 5 is located on the two crawler beams of the crawler chassis 1 and cooperates with the slider of the lifting frame 9;

[0029] A radiator 8 is fixed to the front end of the crawler chassis 1;

[0030] The lifting frame 9 is connected to the crawler chassis 1 through the lifting support 6 and the lifting cylinder 7, and the sliders on both sides of the lifting frame 9 are located inside the guide rail 5;

[0031] The end of the tie-down strap 10 is fixed on the pin above the swing frame 2;

[0032] The drainage pump assembly 11 is placed at the bottom of the L-shaped bottom of the swing frame 2 and is fixed inside the swing frame 2 by the fastener strap 10;

[0033] A hydraulic system 12, located on the crawler chassis 1, is used to connect various components;

[0034] The control box 13 is located at the left rear of the crawler chassis 1 and is used for installing various control components.

[0035] The connection relationship between the above components is:

[0036] The guide rail 5, the lifting support 6, the radiator 8, the hydraulic system 12 and the control box 13 are all arranged on the crawler chassis 1. The swing frame 2 is hinged inside the lifting frame 9. The tie-down strap 10 is located above the swing frame 2. The drainage pump assembly 11 is located inside the swing frame 2.

[0037] The specific working process of the municipal drainage vehicle of this embodiment is as follows:

[0038] When drainage is required, first select a suitable drainage pump assembly according to the drainage requirements and place it on the swing frame, and fix it with a tie-down strap. Then connect the external hydraulic pipeline to the control box of the drainage vehicle, control the track to move, move the drainage pump assembly to the waterlogging point, operate the swing cylinder to retract, swing the drainage pump assembly to a position perpendicular to the water surface, operate the lifting cylinder to lower the drainage pump assembly to the water suction height, and finally control the hydraulic motor of the drainage pump assembly to achieve drainage. The return oil of the hydraulic motor flows back to the hydraulic oil tank through the internal cavity channel of the radiator. When absorbing water, the front end or bottom of the drainage vehicle is completely submerged in water, and the heat of the hydraulic system is carried away by the water suction flow through the radiator fins, thereby achieving the effect of water cooling of the hydraulic system.
