Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of industrial fans, and particularly relates to an industrial fan convenient to move. Background Technique
[0002] Industrial fans are widely used in industrial plants, logistics warehouses, waiting rooms, exhibition halls, stadiums, shopping malls and other large spaces. As a common industrial machine for space ventilation and personnel cooling, industrial fans can most efficiently drive a large amount of air movement, generate ultra-large air volume, form a moving and circulating air flow field in the space, and can effectively regulate the air circulation problem in the industrial production workshop.
[0003] Since industrial fans are large in volume and heavy in weight, universal wheels are usually arranged at the bottom of industrial fans for easy movement. However, industrial fans are heavy in weight and have large vibrations during operation. The contact area between the universal wheels and the ground is small, so the pressure on the ground is large. Long-term fixed positions are likely to cause depressions on the ground. At the same time, the universal wheels are likely to be damaged due to bearing the weight of the fan for a long time. However, without universal wheels, industrial fans are not easy to move. Therefore, an industrial fan convenient to move is needed to retract the universal wheels when the industrial fan is working to avoid ground depression and damage to the universal wheels, and to extend the universal wheels when movement is required to facilitate the movement of the industrial fan.

[0029] Hereinafter, the present disclosure will be described in detail with reference to the drawings and in combination with the embodiments.
[0030] Refer to Figures 1-7As shown in the figure, a kind of industrial fan convenient to move of the utility model includes a base 1, a handle 2 fixedly arranged on the base, an oil pressure mechanism 3 fixedly arranged on the base, a first chute 4 fixedly arranged on the base, a first bracket 8 slidably arranged on the first chute, a blowing mechanism 5 fixedly arranged on the first bracket, a moving mechanism 6 fixedly arranged on the base and the first bracket, and an electric control mechanism 7 fixedly arranged on the base; The moving mechanism includes telescopic components 61 symmetrically and fixedly arranged on the base and the first bracket, a bottom plate 62 fixedly arranged on the telescopic components, and a plurality of rotating components 63 fixedly arranged on the bottom plate; The handle is used to push and pull the industrial fan to facilitate movement; The oil pressure mechanism is used to lift the first bracket and lower the moving mechanism; The blowing mechanism is used to blow air; The moving mechanism can be retracted when the industrial fan is working to avoid ground depression and damage to the moving mechanism, and the moving mechanism can be extended when it is necessary to move, facilitating the movement of the industrial fan; The electric control mechanism is used to control the reset valve and the blowing mechanism to work; The first bracket can slide along the first chute.
[0031] Specifically, the telescopic component includes second chutes 611 symmetrically penetrating through the first bracket, first rotating shafts 612 slidably arranged on the second chutes, second rotating shafts 613 symmetrically fixedly arranged on the base, second brackets 614 symmetrically arranged on the bottom plate, first connecting rods 615 rotatably sleeved on the first rotating shafts and rotatably sleeved on the second rotating shafts and rotatably penetrating through the second brackets, and third chutes 616 fixedly arranged on the bottom plate; The second bracket is slidably arranged on the third chute; The first rotating shaft can slide along the second chute, and the second chute limits the first rotating shaft; The second bracket can slide on the third chute, and the third chute limits the second bracket; In the initial state, the two first connecting rods on the same side form an obtuse angle. When the first bracket moves upward, it drives one end of the first rotating shaft to move upward. Since the second rotating shaft is fixedly arranged on the base and the first connecting rod is sleeved on the first rotating shaft and the second rotating shaft, the first rotating shaft will slide on the second chute and gradually approach, thereby driving the first connecting rod to rotate around the second rotating shaft. The included angle between the two first connecting rods on the same side decreases, and then it drives the second bracket to slide on the third chute and gradually approach. Since the first connecting rod is a connecting rod with a fixed length, when rotating, it will push the bottom plate downward and extend out of the base, that is, lift the base, so that the base is separated from the ground contact, and the universal wheel is in contact with the base. At this time, the industrial fan can be easily moved.
[0032] Specifically, the rotating component includes a first installation groove 631 fixedly arranged on the bottom plate, a third bracket 632 rotatably arranged on the first installation groove, and a roller 633 rotatably penetrating through the third bracket; The third bracket can rotate on the first installation groove, thereby driving the roller to rotate to realize movement in any direction.
[0033] Specifically, the blowing mechanism includes a frame body 51 provided on the first bracket, protective nets 52 symmetrically and fixedly provided on the frame body, a fourth bracket 53 fixedly provided on the frame body, a motor 54 fixedly provided on the fourth bracket, and a plurality of fan blades 55 fixedly provided on the motor; the motor is controlled by an electric control box.
[0034] Specifically, the electric control mechanism includes an electric control box 71 fixedly provided on the base, and a plurality of buttons 72 fixedly provided on the electric control box; the electric control box can control the motor and the reset valve; the buttons are used to set the rotation speed of the motor and the opening and closing of the reset valve.
[0035] Specifically, the oil pressure mechanism includes a first oil cylinder 31 fixedly provided on the base, a fifth bracket 32 fixedly provided on the base, a handle 33 rotatably sleeved on the first oil cylinder and rotatably sleeved on the fifth bracket, a fuel tank 34 fixedly provided on the base, a plurality of second oil cylinders 35 fixedly provided on the base, a first pipeline 36 with one end fixedly provided on the fuel tank and the other end fixedly provided on the first oil cylinder, a second pipeline 37 with one end fixedly provided on the second oil cylinder and the other end fixedly provided on the first oil cylinder, and a sealing component 38 fixedly provided on the first pipeline and the second pipeline; the diameter of the second oil cylinder is several times that of the first oil cylinder. Based on Pascal's principle, since the diameter of the second oil cylinder is several times that of the first oil cylinder, a small force applied to the first oil cylinder and a long movement distance can cause a large force to be generated in the second oil cylinder and a short movement distance, achieving the effect of labor saving; the diameter of the end of the first pipeline connected to the first oil cylinder is slightly larger; the diameter of the end of the second pipeline connected to the second oil cylinder is slightly larger; during use, taking Figure 3 ... as an example, rotate the handle counterclockwise and press it down. Since a sealing component is provided at the end of the first pipeline close to the first oil cylinder, the hydraulic oil in the first oil cylinder is squeezed and enters the second oil cylinder through the second pipeline. At this time, the reset valve is closed, and the second oil cylinder lifts the first bracket, that is, the first bracket moves upward a certain distance on the first chute. Rotate the handle clockwise. At this time, the sealing component in the second pipeline is closed, and the hydraulic oil in the second oil cylinder cannot be discharged, realizing the self-locking function. And the sealing component in the first pipeline is opened, and the hydraulic oil in the fuel tank can be sucked into the first oil cylinder. Rotate the handle repeatedly to fully extend the moving component out of the base, and the industrial fan can be moved. After moving in place, the reset valve is opened through the electric control mechanism, the hydraulic oil in the second oil cylinder can be discharged into the fuel tank, and the first bracket can move downward along the first chute to reset, thereby driving the moving mechanism to reset.
[0036] Specifically, the sealing assembly includes a first spring 381 fixedly arranged on the first pipeline, a first sealing ball 382 fixedly arranged at one end of the first spring, a second spring 383 fixedly arranged on the second pipeline, a second sealing ball 384 fixedly arranged at one end of the second spring, a third pipeline 385 fixedly arranged on the second oil cylinder, and a reset valve 386 fixedly arranged on the third pipeline; the first spring is a tension spring; the second spring is a tension spring; only a part of the surface of the first sealing ball contacts the first pipeline; only a part of the surface of the second sealing ball contacts the second pipeline; the contact area between the first sealing ball and the first pipeline is a small arc; taking Figure 3 as an example, when the handle is rotated clockwise and the oil in the fuel tank enters the first oil cylinder through the first pipeline, the hydraulic oil can push open the first sealing ball, and the hydraulic oil enters the first oil cylinder. When the handle is rotated counterclockwise, the hydraulic oil presses the first sealing ball, making the first sealing ball fit more tightly against the first pipeline, sealing the first pipeline. The hydraulic oil can only enter the second pipeline to push up the second sealing ball and enter the second oil cylinder. When the reset valve is opened, the hydraulic oil in the second oil cylinder can be discharged from the second oil cylinder into the fuel tank, and the second oil cylinder loses pressure to realize the reset of the first bracket and the moving mechanism.
