Problems solved by technology

[0005] But the device of the patent CN102974252A has the following disadvantages: (1) The hydraulic pressure and the spring damping connection can absorb shocks in principle, but if the vibration frequencies of the two are the same or when they reach the intersection point, the amplitudes of the two will be superimposed instead, and then the vibration will be aggravated ; (2) The mechanical connection of the shock absorption system is complicated, and the pins or screws are prone to fall off, the reliability is not strong, and the maintenance is inconvenient; (3) There are no other protective measures

Embodiment 1

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] see figure 1 , 2 , a shock-absorbing electric car for liquid explosives room transfer of the present invention, as can be seen from the figure: the equipment consists of a car body 1, an axle 2, a shock-absorbing system 3, a drive system 4, a control system 5, Power supply system 6, braking system 7, wheel set 8, incubator 9 etc. are made up of parts, and the rated load of present embodiment electric car is 60kg, is used for the workshop transshipment of ammonium azide nitrate.

[0032] see image 3 , the axle 2 and the vehicle body 1 are connected through a shock absorbing system 3; the shock absorbing system 3 includes a shock absorbing spring 17 and a guide column 18, and the type of the shock absorbing system shock absorbing spring is cold coil compression Spring, the material is 60Si2MnA, type C; the impact sensitivity of ammoniu...

Embodiment 2

[0039] The rated load of the electric vehicle of this embodiment is 60kg, which is used for the transfer of nitroglycerin in the workshop.

[0040] see image 3 , the axle 2 and the vehicle body 1 are connected through a shock absorbing system 3; the shock absorbing system 3 includes a shock absorbing spring 17 and a guide column 18, and the type of the shock absorbing system shock absorbing spring is cold coil compression Spring, the material is 60Si2MnA, type C; the impact sensitivity of nitroglycerin liquid explosive is 1, and the rated load is 60kg. According to the functional relationship between the resonant frequency of the shock-absorbing electric vehicle, the sensitivity of liquid explosive and the weight of liquid explosive f(HZ)=0.57x-32y The resonant frequency is calculated to be 2HZ. According to the spring selection formula, the diameter of the spring steel wire is d=25mm, the middle diameter of the spring is D=140mm, and the number of turns is 8.

Abstract

The invention discloses a shock-absorption electric vehicle for transferring liquid-state explosives between workshops. The shock-absorption electric vehicle comprises the parts of a vehicle body 1, avehicle axle 2, a shock-absorption system 3, a driving system 4, a control system 5, a power supply system 6, a braking system 7, a wheel set 8, a thermal container 9 and the like. The shock-absorption system 3 adopts a shock-absorption spring 17 and a guiding column 18, the resonant frequency of the vehicle is calculated through the deadweight capacity and the sensitivity of the explosives, andfurther a model needed by the spring is determined; and multiple protection measures are taken, and an explosion-proof electric machine, reliable grounding, the thermal container, an anti-collision wheel, electroconductive rubber and the like are included, explosive-proof treatment is conducted on an electric control part, and therefore the electric control part can be suitable for transferring the liquid explosives. According to the shock-absorption electric vehicle for transferring the liquid-state explosives between the workshops, the structure is simple, maintenance is simple and convenient, vibration is controllable, and the shock-absorption electric vehicle can adapt to different deadweight capacities and different sensitivity requirements of the liquid explosives by adjusting the model of the spring.

Description

technical field [0001] The invention belongs to the field of electric vehicle manufacturing, and relates to a shock-absorbing electric vehicle, in particular to a shock-absorbing electric vehicle suitable for short-distance transfer in a liquid explosive workshop. Background technique [0002] Liquid explosives such as nitroglycerin, ammonium azide nitrate, etc. are widely used in the explosives industry, but due to their high sensitivity and explosive power, they bring great difficulties to the transfer work. At present, the commonly used liquid explosive transfer methods in my country include pipeline transportation and manual transportation. Among them, the pipeline transportation is suitable for factory production with large demand, and requires operations such as insensitivity, and the cost is relatively high; manual transportation is due to People are in direct contact with liquid explosive barrels, and are affected by factors such as weather and road surfaces, and are ...
